Description

IMPROVED GRAIN CARRIER PBSC PCJ-PN OF INVENTION The present invention relates to carts or wagons for grains and more specifically to a grain cart having an improved Archimedean screw or propeller mechanism and hopper for better control of grain flow. and a novel impulse line assembly and latching assembly for ease of operation. The purpose of the grain carts is to improve the efficiency of harvesting equipment such as combined machines, thus shortening harvest time. While modern combined machines are fast and efficient, problems occur when transporting the grain away from the combine and out of the field. At any time that the combined machine stops to discharge, valuable cutting time is lost - up to one third of the machine's total harvesting capacity. This quickly translates into lost money. When a large combine works in a cornfield of 1.29 x 10"3 m3 / m2 (150 bus els per acre), it can harvest approximately 95.04 m3 (2,700 bushels) per hour, but if it is required to have and discharge, this potential can be cut to as little as 59.4 m3 (1,688 bushels) per hour The loss of 35.2+ m3 (1,000+ bushels) of production per hour will be multiplied to an impressive loss of 352+ 3 (10,000 bushels) in a day's work This problem of lost production is even more significant when it is full small combined machines.The loss of production of combined machines is not only the only difficulty that the farmer faces during the harvest.Big trucks are sometimes used to transport grain They often do not perform well in muddy or arduous field conditions, and in wheat fields, a truck in the field can easily cause a catastrophic fire. solution to these problems. The grain carts usually comprise a grain hopper or drawer placed on a rolling frame, in combination with helical means or mechanism for unloading the grains from the hopper. Productivity increases dramatically with the use of grain carts, because the combined ones never require stopping to unload. On the other hand, the grain of the combined hopper is discharged to the grain cart when advancing. Furthermore, a single grain cart can usually service one or more combined machines, first by unloading one, then the other, and transporting the harvested grain to a waiting truck, whenever necessary. Grain carts also handle soft or arduous fields with ease and since they are pulled behind a tractor, fire hazards are minimized.

Because they offer a combination of economy, versatility, production savings and maneuverability, grain carts have been widely accepted by farmers and are widely produced by equipment manufacturers. However, there are still problematic obstacles to overcome in the construction of a grain cart. It is the purpose of the present invention to overcome these obstacles. A problem commonly encountered by grain car operators is the difficulty in visually determining the position of the propeller mechanism. Most grain carts have propeller mechanisms that include a folding grain duct. Determine the position of the grain duct is important to avoid damage to the duct and hopper. The grain duct usually bends and unfolds a number of times a day. If the tractor operator can not determine the position of the grain duct from the driver's seat, it must jump out and into the tractor to verify the position of the duct, wasting time and risking injury. Attempts have been made to solve this problem in cars that have propellers that bend down the side of the hopper through the use of propeller position indicators, but these indicators can fail and can be difficult to see due to dust or wear. Another common problem with grain carts is that the grain conduit is projected, when in the folded transport position, beyond the back of the hopper. This creates a driving hazard, both for the tractor operator and road and road users, and increases the possibility of damaging the propeller mechanism when the car is pulled back into a building for storage or otherwise maneuvered in closed areas. The prior devices also have helical mechanisms that extend through a wall of the hopper such that there is a helix structure contained within the grain hopper. This internal helix structure can significantly deteriorate the grain separation of a hopper by preventing downward grain flow, by letting grains escape to the collector causing a high starting torque, and by reducing the depth of the collector area of the hopper. The propeller mechanism may also include hydraulic cylinders and the like that leak and contaminate the grain. The fact that these mechanisms are located inside the hopper makes routine maintenance more difficult, and in the case of a hydraulic failure of the interruption mechanism when the car is loaded, it is impossible to unload the car with the propeller. Two types of impulse systems are used in today's trucks - PTO or PTO-drive and hydraulic impellers. A problem arises if you want to change between the two, such as due to tractor failure. For example, if a grain cart was used for the last time with a PTO mechanism, to change to hydraulic pulses, the operator would need to crawl under the car to release the PTO drive mechanism of the car, from the propeller gearbox and install a hydraulic impeller. The same is true when moving from the hydraulic impeller back to PTO. This of course is very time consuming. Furthermore, some systems do not provide a type of drive system that allows the operator to easily vary the rotational speed of the propeller for unloading. On the same line, problems are often encountered when coupling carts for grains and other implements to tractors and traction vehicles. Normally, an implement would have a simple tongue hitch or fork hitch for connection to the tractor. If the implement hitch is not complementary to the tractor hitch, either the implement hitch or the tractor hitch must be removed and replaced before engaging. It is therefore an object of the present invention to provide an improved grain cart having a hopper with walls that are interleaved and formed around propeller assemblies in such a way that the hopper is devoid of an internal helix structure, providing In this way clean flow lines for grain and a deeper bottom to facilitate grain removal and cleaning.

A further object of the invention of the Applicant is to provide propeller assemblies for a grain cart, the propeller assemblies have a door for interrupting grains and related mechanisms positioned outside the hopper, such that the door is less tending to leak and be easily serviced. Another object of the present invention is to provide an improved grain carrier having a propeller assembly positioned in a front corner of the carriage, in the form of providing the operator of the tractor with visibility of a grain conduit flange from which the operator You can easily determine the position of the duct. A further object of the invention is to provide a grain cart with a helix assembly having a grain conduit engineered such that while it is of sufficient duct length, the duct does not project beyond the back of the duct. the hopper when it is in the transport position. A still further object of the invention is to provide an optional pulse line assembly for a grain carriage, whereby the carriage can be quickly converted between PTO pulse configurations as a hydraulic pulse. A related objective is to provide an impulse line assembly whereby the rotational speed of the helix system can be varied.

Another object of the invention is to provide a combined simple tongue and fork hitch that will allow the improved grain cart and other implements to be coupled to a tractor, regardless of the type of hitch mounted on the tractor. These and other objectives and advantages are provided by the improved grain cart. The invention includes a mobile frame adapted to be pulled by a vehicle such as a tractor. The frame supports a grain hopper or drawer. The hopper has an insert front corner area formed by the walls of the hopper. A propeller assembly is provided to discharge the grain from the hopper, the propeller assemblies are located completely outside the hopper. The propeller assemblies include a manifold for receiving grain from the hopper, the manifold is placed on an outer wall portion, lower for the front corner area of the insert. Between the collector and the surface of the portion of the outer wall of the front corner area of the insert there is a door for grain interruption to control a flow of grain from the hopper to the collector. A hydraulic cylinder adjacent to the manifold is mounted outside the hopper and connected to the grain interrupter door to open and close the door. A conduit is connected to the manifold, and mounts are provided to transport grain through the conduit. In accordance with other aspects of the invention, the improved grain cart includes a grain hopper having interior surfaces and an open rectangular lid that converge to the bottom of the hopper. The hopper also has an insert front corner area formed by the hopper walls whose interior surfaces also tip downwardly from the bottom of the hopper. The propeller mounts for unloading grain from the hopper are located completely outside the hopper and are inclined approximately 50 ° to the car frame. The grain conduit includes a lower helix tube connected to the manifold at its first end and having a flange at its second end and an upper helix tube having a flange at its first end complementary to that of the lower helix tube. The propeller and flange are positioned in such a way that an operator can visually inspect the upper propeller pipe flange from the tractor seat to determine the position of upper propeller tubes in relation to the hopper. Another aspect of the invention is an impulse assembly for transporting grain through the grain conduit. The thrust assembly includes a gearbox adapted to connect to the propeller blades or pallets disposed within the conduit, and an impulse arrow of sufficient length to extend forward of the front of the hopper to engage the gearbox. The pulse arrow can be adapted with one or more sprockets and is also adapted to receive a complementary PTO coupling. A hydraulic motor having one or more sprockets aligned in an operative relation to the sprockets of the impulse shaft can be provided in such a way that the impulse shaft can be hydraulically displaced by a chain connecting the sprockets of the shaft arrow. impulse with the gearwheels of the motor or displaced by PTO. The optional hydraulic motor is mounted in an adjustable manner so that the size of the sprockets and the chain can be changed to vary the rotational speed of the blades. The collector can also be provided with a pit discharge door. Still another aspect of the invention is the latch assembly, which includes an arrow and two latching parts. A first hook part is connected to the arrow, the first hook part has a vertical portion for coupling with the arrow and a horizontal portion having a through hole. A second coupling piece is placed on and parallel to the horizontal portion of the first coupling part, such that there is a space between the second coupling part and the horizontal portion of the first coupling part, the second coupling part. it has a through hinge hole aligned with the hinge hole of the first hitch part. The novel design of the improved grain cart leads to numerous advantages. Many benefits arise from the location of the propeller mounts in a front corner area of the hopper insert. Since the propeller is placed in the corner of the car, and because the propeller flanges are visible, the operator of the car, ie the driver of the tractor, can visually inspect the flange of the upper propeller tube from the seat of the tractor , to determine the position of the propeller tube. In this way, in opposition to not being able to see the upper helix tube or based on a faulty or partially blocked position indicator, the operator can rely confidently on a visual inspection, without having to leave the tractor. This prevents damage to the upper helix system during bending and transport. The placement of the propeller assemblies in a front corner of the carriage also allows sufficient propeller length without having to extend the upper propeller tube past the rear of the carriage when in its bent position. The total carriage width is optimized as the upper helix tube is stored within the carriage floor lines. Consequently, transportation hazards are minimized. Providing the hopper with an insert front corner area makes it easy to move the propeller mounts out of the hopper and simultaneously creates a deeper hopper bottom, promoting grain flow. Because the propeller mounts are located outside the hopper, maintenance capacity is improved. Construction methods are simplified since the grain interrupter door is constructed to slide on an exterior wall panel of the hopper. Due to this construction, the door for grain interruption has less tendency to leak than conventional systems. It can also be easily serviced from outside the hopper in the event of a problem. Furthermore, since the hydraulic cylinder acting on the grain interrupter door is placed adjacent to the collector, instead of inside the hopper, grain contamination by hydraulic fluid is prevented. The hydraulic cylinder cup is also better protected against damage, such as by kinking and rusting, since the arm does not extend when the grain interruption door is closed. This differs from other systems where the hydraulic cylinder arm is in an extended extended position when the grain interrupter door is closed. Another significant advantage for the invention is that the grain flow within the hopper remains unobstructed. Since a front corner of the car is inserted to form around the external helix means, the interior of the hopper remains free of obstructions common to prior art machines. The interior of the hopper in this way is more uniform and cleaner, allowing better flow of the grains and easier cleaning of the hopper. Additional benefits are provided by the novel impulse line assembly, which assists the operator in rapidly switching between a PTO-driven propeller assembly, and a hydraulically directed propeller assembly. Instead of crawling under the hopper to connect and disengage drive mechanisms, the operator of the invention can easily switch from one drive mechanism to the other, by making simple adjustments to a pulse line assembly located forward of the hopper in the frame. of the car. Since the impulse line assembly includes a sprocket-directed arrow for hydraulic PTO operation, the only conversion changes required are to install (or remove) a chain and remove (or install) a PTO coupling. Furthermore, the rotational speed of the propeller steps can be increased or decreased by changing the size of the sprockets to minimize the time of car discharge. The universal hitch also saves time and money by eliminating hitch replacements and exchanges. A better understanding of the invention and these and other objects and advantages will be obtained from the following description taken in conjunction with the appended claims and drawings.

FIGURE 9a is a top view of the latch assembly. FIGURE 9b is a side view of the latch assembly. Now with reference to FIGURE 1, the improved grain cart of the Applicant includes a frame 10, the frame 10 is provided with an axle assembly 11 and a plurality of wheels 14 (left wheel illustrated is hidden). The frame 10 in this manner is adapted to be pulled by a vehicle, such as a tractor or heavy truck. It will be understood that although the frame 10 is illustrated to have a single-axis mechanism, it can be easily provided with a dual or multi-axis mechanism or even a motorized drive mechanism, all known in the art. A hopper or grain box 20 is supported on the frame 10 by a number of columns 15 and diagonal braces 16 to impart stability and integrity. The hopper 20 is further provided with a lower central band 21 and an upper central band 22 for added support and strength. Illustrated fixed to and extending from the front left corner of the hopper 20 is a helical assembly generally indicated by the numeral 42. While the purpose of the hopper 20 is to retain grain or other granular material loaded there, the function of the assemblies of propeller 42 is to discharge this material from hopper 20. Propeller assemblies 42 are located completely outside of hopper 20. Propeller assemblies 42 include a manifold 30 for receiving grains from hopper 20, the collector 30 is placed in an outer, lower wall portion of the hopper 20. A grain sealing gate (not shown in FIGURE 1) is provided to control a flow of grain from the hopper 20 to the collector 30. The grain sealing gate is located between the collector 30 and the surface of the exterior wall portion of the hopper 20. A first hydraulic cylinder 31 is mounted adjacent to the collector 30 and is connected to the grain interrupter door for opening and closing the door. A conduit is connected to the manifold 30 to provide an enclosure for transporting grains from the hopper 20 to a receptacle. Still with reference to FIGURE 1, the conduit preferably comprises a lower helix tube 33 connected to the manifold 30 at its first end and having a flange 39a at its second end. An upper helical tube 34 is coupled to a lower helix tube 33 by a hinge mechanism 36. The upper helical tube 34 has at its first end a flange 39b complementary to that of the lower helical tube flange 39a. The hinge mechanism 36 operates in such a manner that when deployed or unfolded, the upper propeller tube 34 bears against the upper case panel 25 of the hopper 20. The hinge mechanism 36 is preferably hydraulically controlled using the hydraulic pump. central of the tractor. A second hydraulic cylinder 48 connects the bevelled upper case panel 25 to the upper helical tube 34. At the terminal end of the upper helix tube 34 is an outlet 37 and an end cap 38. The outlet 37 and the end cap 38 function to control the flow of grain through the conduit and into the receptacle.

A means is provided for transporting grain from the hopper 20 through the manifold 30 and propeller tubes 33, 34 and into the receptacle. As illustrated in FIGURE 1, the preferred assemblies comprise a helix blade 35 also known as a helical helix. Means such as a pallet conveyor would suffice. A gearbox (not shown in FIGURE 1) adapted to move vanes 35 acts under the manifold 30 and is connected by a universal joint to a pulse arrow 43. The impulse arrow 43 couples the gearbox which in turn Pallets 35. In FIGURE 1, the pulse arrow 43 is illustrated without a safety cover. In operation, however, a safety cover must be connected. The pulse arrow 43 runs from the gearbox to a pulse line assembly housed under the motor cover 12. The pulse line assembly is described further below. Now with reference to FIGURE 2a, the hopper 20 and the propeller assemblies 42 are illustrated in a perspective view. From this view, it is clear that the hopper 20 has an insert front corner area 50. In FIGURE 2a, the insert front corner area 50 is illustrated in the left front corner of the hopper 20. This is the preferred location for the front corner area of the insert, since most tractor operators dismount on the left side and are more comfortable looking over their left shoulder to maneuver and check the grain cart. For detailed transcription purposes, the left and right sides of the carriage are determined with reference facing the direction of travel. The front corner area of the insert 50 is formed by the walls of the hopper 20. This area can best be appreciated by comprising the construction of the hopper 20, as illustrated collectively in FIGS. 2a and 2b. The hopper 20 is constituted by a front upper case panel 23, a rear upper case panel 24 and two side top case panels 25, 26. While the side top panel 26 is oriented vertically, it is seen in FIGURE 2b that the upper side box panel 25 is of a beveled shape. The beveled nature of the upper side box panel 25 maximizes the carriage width and gives the upper propeller tube 34 a rest position when the carriage is in its transport position. The upper case panels 23-26 form a rectangular cover open to the hopper 20. Four large inclined blades 27a-d constitute the walls of the hopper 20. The inner surfaces of the sheets 27a-d are tilted converging towards the bottom of the hopper. A number of smaller lid sheets 28 are disposed at the bottom of the hopper to provide a clean, uniform hopper bottom surface. As seen further in FIGURE 2b, two slanted blades 29a, 29b, also known as helix cutting blades, define the inner surface of the insert front corner area 50. Both helix cutting blades 29a, 29b converge toward the hopper bottom. The propeller cutting blade 29 is configured to have an opening complementary to the dimensions of the grain sealing door 32. FIGURE 2a more clearly shows the propeller assemblies 42 fitted with the insert front corner area 50. The manifold 30 is welded to a lower outer wall portion of the insert front corner area 50. Two views of the manifold 30 and the lower propeller tube 33 before installation are illustrated in FIGS. 4a and 4b. In FIGURE 4a, in a top view, the manifold 30 is illustrated as provided with a door opening for sealing grain 60 and an optional opening 61 for a pit discharge door. A track assembly for pit door 65 is also illustrated. FIGURE 4b is a side view after connection of the collector 30 to the outer wall of the front corner area of insert 50. Both views show a gearbox generally indicated by reference numeral 70. A gearbox arrow 72 connects gearbox 70 to propeller vanes 35. Propeller vanes 35 move to one side of the manifold 30 as illustrated more particularly in FIGS. 5 and 6. The grain seal door 32 is located between the manifold 30 and the surface of the outer wall portion of the insert front corner area 50. The assembly of the grain sealing door 32 to the manifold 30 and the exterior wall portion of the insert front corner area 50 is more clearly illustrated in FIGURE 5. FIGURE 5 is a bottom view of the components of the manifold 30 and vanes 35 of the invention. As illustrated, there is a space for mounting grain sealing door 51 disposed between the outer wall portion of the insert front corner area 50 and the manifold 30. With reference to FIGURE 2a, the grain sealing door 32 is provided with a tongue 40 which is connected to a first hydraulic cylinder 31. The first hydraulic cylinder 31 is connected to the central hydraulic pump of the tractor and controlled from the tractor cab. The first hydraulic cylinder 31 works to open or close the grain sealing door 32 as desired, and is mounted adjacent the manifold 30 outside the hopper 20. The manifold 30 can also be provided with a pit discharge door 41 to allow the straight fall of grains from the hopper 20 through the collector 30 to a pit collection area. The lower propeller tube 33 is welded to the manifold 30 and extends approximately to the upper central band 22 of the hopper 20. The end of the lower propeller tube 33 connected to the manifold 30 is said to be at a first end, while that the end of the lower helix tube 33 adjacent the hinge 33 is defined as a second end. At this second end, the lower propeller tube 33 is provided with a flange 39a for coupling with the flange 39b of the upper propeller tube 34. When the improved bead carrier of the present invention is in the transport position or bent as shown in FIG. illustrated in FIGURE 3, the upper propeller tube flange 39b is distinctly visible by the vehicle or tractor operator. This allows the operator to quickly determine the position of the upper propeller tube 34 in relation to the hopper 20. As previously mentioned, in its bent position the upper propeller tube 34 bears against the upper bevel side panel panel 25. As a whole, the propeller assemblies 42 are tilted approximately 50 ° with respect to the frame 10. With this degree of inclination, the propeller assemblies 42 are capable of reaching discharge heights similar to conventional bead carts. Also as illustrated in FIGURE 3, the upper propeller tube 34 when supported, does not extend beyond the rear of the upper case panel 24. FIGURE 6 shows a view taken through the lower propeller tube 33. from the flange 39a to the collector 30. This view shows the spatial relationship of the flange 39a to the collector 30. This relationship allows operative coupling of the upper helix tube 34 to the lower helix tube 33, while at the same time allowing the upper propeller 34 leans against the upper case panel 25, when in the transport position. FIGURE 7 is a pulse line assembly illustration showing the components of the propeller vane drive mechanism. The pulse arrow 43 is connected to a universal joint (not shown) in the gearbox 70 (not shown in FIGURE 7). A first bearing 122a, and a locking latch collar 122c slide on the pulse arrow 43 approximately .61 m (2 ft.) From the front end of the thrust arrow 43. Two bearing flanges 121a, 123a, sandwich the first bearing 122a. Flange 121a contains a grease insert. A bearing and motor mounting plate 116 is placed on the pulse arrow 43 in front of the first bearing 122a. The first bearing 122a and the flanges 121a, 123a are bolted to the mounting plate 116 with three bolts, nuts and locking washers, such as bolt 128, locking washer 131 and nut 133. A hydraulic motor 101 is connected by four bolts to a motor mounting plate 120. The motor mounting plate 120 is then placed in front of the bearing and motor mounting plate 116 when fixed with four bolts. . A first gear 112 and a bushing 114 are assembled with two sets of screws 150. An impulse key 134 is then inserted into the keyway of the hydraulic motor shaft. Subsequently, the assembly of gear wheels (112, 114) is arranged on the output shaft of the motor. A second sprocket 111 is also assembled to a hub 113 with two sets of screws 151. A pulse key 135 is inserted into a keyway that is located approximately 20.32 cm (eight inches) from the front end of the impulse shaft 43 The gear wheel assembly of the pulse shaft (111, 113) is placed on the pulse arrow 43 and key 135 with the adjustment screws facing the front of the carriage. A front bearing assembly 140 is connected to a transverse mounting frame member 19 as illustrated particularly in FIGURE 8a. A second bearing 122b, and interlocking collar 122d and flanges 121b, 123b, are positioned against the front bearing assembly 140 with bolts, locking washers and nuts. The bearing flange 121b also contains an insert (zert) for grease. Two side plates 117, 118 connect the front bearing assembly 140 to the mounting plates 116. The left side plate 118 is slightly longer than the right side plate 117 to keep the motor 101 in line with the pulse arrow 43 The pulse arrow gear 111 can be aligned with the hydraulic motor gear 112 in view. One or more of the sprockets 111, 112 are replaceable and the hydraulic motor 101 is adjustably mounted such that the size of the sprockets 111, 112 and the chain 115 can be changed to vary the rotational speed of the blade. propeller. A chain 115 operatively connects the driving arrow gear 111 with the hydraulic motor gear 112. An anti-rotation bar 119 is connected to the two bottom holes in the mounting plate 116 between the frame channels with bolts, flat washers, lock washers and nuts. FIGURE 8a helps show the placement of the different mounts used in the placement of the impulse line components. Turning now to FIGURE 8b and a top view of the hydraulic components of the pulse line assembly, a T-connector 160a-b is threaded into each of the check valves 102. The check valve 102 ensures that paddles 35 can be operated only in your forward direction. An accessory 108a-b is installed in each T-connector 106a-b such that both elbows are directed to the front of the carriage. The male ends of the two hoses 104a-b are connected to bends 108a-b. Two O-ring connectors (not shown) are inserted in the gates in the hydraulic motor 101. The male ends of two hoses 105a-b are connected to T-connectors 106a-b and female oscillating ends then connected to the hydraulic motor 107.

A front pulse arrow shield 142 and a rear pulse arrow shield (not shown) shall be placed on the pulse arrow 43 for safety purposes. A clutch cover 141 is installed on the front bearing assembly 140. The check valve assembly 102 can then be clamped by the clamp to the clutch cover 141 for added stability. When the car is in its coupled hydraulic displacement mode, the fluid flows under pressure from the tractor's central hydraulic pump through the hoses 104b, 105b and the associated tooling to operate the hydraulic motor 101. The fluid flows back to the tractor system from the hydraulic motor 101 through return hoses 104a, 105a. The carriage is switched from hydraulic displacement to PTO by removing the chain 115 and coupling a PTO arrow to the pulse arrow 43. This is achieved by loosening the four bolts located on the motor mounting plate 120, so that the motor Hydraulic 101 can be raised to provide chain 115 with clearance. After the chain 115 has been removed, the four bolts on the motor mounting plate 120 become squeezed. The PTO arrow of the tractor is then connected to the forward end of the pulse arrow 43. Hydraulic hoses 104a-b shall be connected out of the way so as not to interfere with the PTO arrow. To switch from PTO to hydraulic impulse, the previous process is inverted.

FIGURES 1, 9a and 9b show a hook 200 for use in connection with the improved grain cart described herein. The hitch 200 can be described generally as a changeable fork / tractor hitch. Up to the arrow, most of the grain carts were provided with either a single tongue or tractor hitch, hitch or fork hitch. The hitch can work as either a center-band hitch or a fork hitch. FIGURE 9a is a top view of the latch. The hitch 200 includes an arrow 201 having a bore hole 202 drilled through at one end. At the other end of the arrow 201 is located a first hook part 203 referred to as an L-shaped hook washer. The hook washer 203 has a vertical portion as a receiving hole 206 for coupling with the arrow 201 and a horizontal portion. having a through hole 207. A second coupling piece 204 referred to as a single tab, is welded on and parallel to the horizontal portion of the coupling washer 203 on the central axis of the arrow 201, such that there is a space created between the single tab 204 and the horizontal portion of the locking washer 203. The single tongue 204 is also provided with a hinge hole 208. A wear plate 205 is fixed to the bottom of the single tongue 204. The wear plate 205 is similarly provided with a hinge hole 209. The hinge holes 207-209 are aligned. If the hitch is to be used as a tractor hitch, a pin (not shown) of sufficient length is used for coupling the tractor hitch 204 alone. In other words, the pin should not be long enough to pass through the hinge hole 207. On the other hand, if the hitch is to be used as a fork hitch, a pin of sufficient length to pass through all the Joints 207-209 must be used. Instead of changing hooks, an operator simply has to choose the appropriate pin to use with the latching mechanism. In use, the tractor operator engages the traction hook of the tractor or other hitch, with the hitch 200 of the grain cart which preferably is the universal hitch. It is coupled either PTO or hydraulic displacement and the appropriate hydraulic connections are made between the tractor and the hydraulic cylinders 31, 48. The door for sealing of grain is closed 32. The grain cart is filled by a combined or other source of grains and moves in its transport position to a discharge area. There, the grain conduit is unfolded by the action of the second hydraulic cylinder 48 and hinge mechanism 36, and the grains are discharged from the hopper 20 by the propeller assemblies 42.
