Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings and embodiments thereof.

Example 1

Referring to fig. 1-10, the present embodiment provides a long span balanced traction system for a stockhouse, comprising: a guide rail, a moving mechanism, and a traction rope 34; the guide rails comprise a first guide rail 11 and a second guide rail 12, and the first guide rail 11 and the second guide rail 12 can be installed in parallel after being separated from each other by a certain distance; after being installed, the two groups of guide rails have a first tail end and a second tail end in the same direction, wherein one end of the first guide rail is a first tail end 13a of the first guide rail, and the other end of the first guide rail is a second tail end 14a of the first guide rail; one end of the second guide rail is a first end 13b of the second guide rail, and the other end is a second end 14b of the second guide rail;

the moving mechanism comprises a first moving block 21 and a second moving block 28, and the first moving block 21 and the second moving block 28 are respectively in sliding fit with the first guide rail 11 and the second guide rail 12;

wherein, a first pulley 22 is arranged on the first moving block 21, and a second pulley 29 is arranged on the second moving block 28; the first pulley 22 and the second pulley 29 are respectively disposed on the first moving block 21 and the second moving block 28 near the first end 13a of the first guide rail and the first end 13b of the second guide rail;

wherein the traction rope 34 has a fixed end 35 and a traction end 36, the fixed end 35 is fixed at the first end 13b of the second guide rail;

the traction end 36 sequentially passes through the second pulley 29 and the first pulley 22 and then is led out from the first tail end 13a of the first guide rail;

after the first moving block 21 and the second moving block 28 are mounted, a functional component connecting position 56 is arranged on one side of the first moving block and the second moving block, which are close to each other.

The unbalanced traction force applied to the moving mechanism can cause the moving mechanism to move on the two guide rails at different speeds to generate skew, so that the moving mechanism is jammed or even dead in the moving process.

In the technical scheme provided by this embodiment, two sets of pulleys are arranged on the first moving block 21 and the second moving block 28, and the traction rope 34 sequentially passes through the two sets of pulleys, when the moving mechanism is pulled, only the traction end 36 of the traction rope 34 needs to be pulled, because the fixed end 35 of the traction rope 34 is fixed, when the traction end 36 is pulled, the traction rope 34 simultaneously applies traction force to the first pulley 22 and the first pulley 22, and thus the first moving block 21 and the second moving block 28 can simultaneously move on the first guide rail 11 and the second guide rail 12, so that the moving mechanism is pulled in a balanced manner.

Compared with the prior art, the traction mechanism is provided with one traction point, the central position of the moving mechanism is difficult to find for traction, and the whole moving mechanism is easy to deflect after one side edge is blocked during traction. If the pulling points are disposed on both sides of the moving mechanism and the pulling force is applied simultaneously, the difference between the magnitude of the applied force and the applied time will also cause the moving mechanism to deflect. According to the technical scheme adopted by the embodiment, two ends of the moving mechanism can move simultaneously only by applying one traction force, and the application requirement on the traction force is low.

The first guide rail 11 and the second guide rail 12 are used for being installed and fixed in a working environment and providing directional guide for the first moving block 21 and the second moving block 28. The first rail 11 comprises a first end 13a of the first rail and a second end 14a of the first rail, and the second rail comprises a first end 13b of the second rail and a second end 14b of the second rail.

The functional component connecting position 56 is used for connecting and installing a functional component, the functional component described in this embodiment may be a scraper 40 for hanging the bottom of the dung trough 60, two ends of the scraper 40 are connected with the functional component connecting position 56, when the traction end 36 of the traction rope 34 is pulled to move, the first slider and the second slider simultaneously drive the scraper 40 to move, the scraper 40 contacts with the bottom of the dung trough 60, and slides at the bottom of the dung trough 60, so as to scrape off excrement on the dung trough 60. In some embodiments, the functional connection locations may be in the form of insertion holes or slots to be inserted into the scrapers 40, or may be in the form of threaded holes to fix the scrapers 40 to the first moving block 21 and the second moving block 28 through bolts.

In other embodiments, the functional assembly may be configured as another mechanism with a large width-direction span and requiring directional movement, such as a cargo transfer pallet or the like, which can be pulled by the large-span balanced traction system provided in this embodiment.

The pulling end 36 of the pulling rope 34 can be selectively pulled by a winch, a manual winch, or a hand, depending on the pulling objective.

Example 2

Referring to fig. 5-6, further, a strain spring 23 and a connecting block 24 are disposed on the first moving block 21;

wherein the length direction of the strain spring 23 is the same as the direction of the guide rail; one side of the strain spring 23, which is far away from the first tail end 13a of the first guide rail, is connected with the first moving block 21, and one side of the strain spring 23, which is close to the first tail end 13a of the first guide rail, is connected with the connecting block 24;

wherein the side of the connecting block 24 close to the first end 13a of the first guide rail is connected to the first pulley 22.

The embodiment is provided on the basis of embodiment 1, and by the technical scheme provided in embodiment 1, the moving mechanism can be subjected to balanced traction, and at this time, if a force applied to the traction end 36 of the traction rope 34 is suddenly increased (for example, a machine is suddenly and quickly started in a traction manner, or a pull-type is intermittently and strongly dragged), the moving speed of the first moving block 21 close to the traction end 36 of the traction rope 34 may be suddenly increased, so that the moving mechanism after being connected with the functional component is deflected, and a limit contact surface between the moving mechanism and the guide rail is twisted, so that the moving mechanism is subjected to a jerking phenomenon, and even is stuck to the guide rail.

In the technical solution provided in this embodiment, the first pulley 22 is connected to the first moving block 21 through the connecting block 24 and the strain spring 23, when the pulling force of the pulling end 36 is suddenly increased by the applied force, the strain spring 23 on the first moving block 21 is stretched, and the distance between the first pulley 22 and the first moving block 21 is lengthened, so as to compensate the deflection caused by the side of the first moving block 21 being faster than the moving speed of the second moving block 28, and avoid the jerk and the jam on the guide rail when the moving mechanism is pulled.

After the acceleration applied to the pulling end 36 is reduced, the strain spring 23 returns from the stretched state to the contracted state, and the first moving block 21 and the second moving block 28 return to the balanced movement.

Springs with different specifications can be set as the strain spring 23 according to different application scenes, and the specific critical tension of deformation of the strain spring 23 during stretching is larger than the tension required for driving the strain spring 23 to move during working, so that the strain spring 23 cannot be stretched during normal traction.

Example 3

Referring to fig. 6-10, further, the connecting block 24 further comprises an abutting rod 25 thereon, and the abutting rod 25 comprises a hinged end 251 and an abutting end 252;

the side edge of the connecting block 24 along the moving direction of the guide rail is provided with a hinge seat 241, and the hinge end 251 is in hinge fit with the hinge seat 241;

the first guide rail further comprises a limiting piece, the limiting piece is fixedly connected with the first moving block 21, the limiting piece is provided with a first limiting edge 32 and a second limiting edge 33, the first limiting edge 32 is arranged on one side close to the first tail end 13a of the first guide rail, and the second limiting edge 33 is arranged on one side close to the second tail end 14a of the first guide rail;

the abutting rod 25 passes through the space between the first limiting edge 32 and the second limiting edge 33, and the first limiting edge 32 and the second limiting edge 33 limit the abutting rod 25 to move relative to the connecting block 24 in the moving direction of the first moving block;

the distance from the limiting member to the first end 13a of the first guide rail is less than the distance from the hinge base 241 to the first end 13a of the first guide rail, so that one side of the abutting end 252 of the abutting rod 25 is inclined to point to the direction of the first end 13a of the first guide rail;

the guide rail further comprises an abutting plate 15, and the abutting plate 15 is arranged on one side close to the abutting end 252;

the abutting plate 15 has an abutting surface 151, and the abutting end 252 of the abutting rod 25 can abut against the abutting surface 151.

The present embodiment is proposed based on embodiment 2, and in embodiment 2, if the traction force applied to the traction end 36 of the traction rope 34 is excessively increased, which causes the moving mechanism to be completely stuck on the track after deflection, the deflected moving mechanism is not easily restored to the state of balanced movement by the deformation of the strain spring 23.

In the present embodiment, the abutting end 252 of the abutting rod 25 hinged to the connecting block 24 is obliquely directed to the first end 13a of the first guide rail, when the strain spring 23 is stretched and the connecting block 24 moves toward the first end 13a of the first guide rail relative to the first moving block 21, the hinged end 251 of the abutting rod 25 moves toward the first end 13a of the first guide rail relative to the first moving block 21 together with the connecting block 24, and due to the restriction of the first limit edge 32, the abutting rod 25 cannot move directly toward the first end 13a of the first guide rail, but is restricted to rotate, so that the abutting end 252 of the abutting rod 25 rotates toward the second end 14a of the first guide rail and extends toward the abutting surface 151, until the abutting end 252 stops rotating after abutting against the abutting surface 151, the abutting end 252 abuts against the abutting surface 151 in the vicinity of the first moving block 21, the movement of the first pulley 22 is fixed, and the pulling of the pulling rope 34 is continued, and at this time, the pulling of the second pulley 29 in the moving direction changes the movement of the movement mechanism, and the movement of the dead-movement mechanism can be delayed. When the moving mechanism continues to move, the strain spring 23 contracts, and at the same time, the connecting block 24 drives the hinged end 251 of the abutting rod 25 to move towards the second end 14a side of the first guide rail relative to the first moving block 21, and the hinged end is blocked by the second limiting edge 33 arranged at the second end 14a of the first guide rail, so that the abutting end 252 of the abutting rod 25 rotates towards the first end 13a side of the first guide rail, and is separated from the contact with the abutting surface 151.

In some embodiments, the first limiting edge 32 and the second limiting edge 33 are corner edges formed by intersecting two edges, or a narrow surface formed by a narrow plate, or a cylinder with a smaller diameter, which can limit the movement of the abutting rod 25, and provide a rotating space for the abutting rod 25, so that the abutting rod 25 can rotate at a certain angle and can move relative to the first limiting edge 32 and the second limiting edge 33.

In this embodiment, the hinge end 251 may be configured as a shaft hole, and the hinge seat 241 is a rotating shaft, and the shaft hole and the rotating shaft are hinged to realize the rotation of the abutting rod 25.

Example 4

Referring to fig. 6 to 8, further, the abutting rods 25, the limiting members and the abutting plate 15 are two groups; and the number of the first and second electrodes,

the two groups of abutting rods 25 and the limiting pieces are symmetrically arranged on two side edges of the first moving block 21, and the two groups of abutting plates 15 are symmetrically arranged on two side edges of the guide rail.

With the technical solution provided in the present embodiment, when the strain spring 23 is stretched, the abutment rods 25 extend from both sides of the first moving block 21, respectively abut against the abutment surfaces 151, and fix the positions of the connecting block 24 and the first pulley 22 on the guide rail.

Two sets of butts pole 25 are in the relative butt in connecting block 24's both sides, guarantee that connecting block 24 can be stable fix.

Example 5

Referring to fig. 6-8, further, the abutting end 252 is provided with a locking piece 254, and the locking piece 254 includes a locking surface 255 and a connecting end 257;

wherein, a friction material 256 is laid on the locking surface 255;

the connecting end 257 is rotatably connected to the abutting rod 25, so that the locking surface 255 can abut against the abutting surface 151.

The abutting end 252 directly contacts the abutting surface 151 through a hard material, and the contact area after rotational abutment is small, and the friction force generated after contact is small, so that the fixing effect on the connection block 24 is deteriorated.

In this embodiment, the lock piece 254 is rotatably connected to the abutment lever 25, and after the lock surface 255 of the lock piece 254 abuts against the abutment surface 151, the lock surface 255 of the abutment lever 25 is pushed parallel to the abutment surface 151 by the pressing of the abutment lever 25, and the contact area between the lock surface 255 and the abutment surface 151 is increased to increase the frictional force after the abutment.

The friction material 256 applied on the locking surface 255 further increases the friction force, and reduces the sliding distance between the locking surface 255 and the contact surface 151. In some embodiments, friction material 256 may be rubber, flexible plastic, or the like.

Example 6

Referring to fig. 7-8, further, the abutting rod 25 near one side of the hinged end 251 is a triggering elastic sheet 253, and the triggering elastic sheet 253 has the performance of deforming after being pressed and resetting after being deformed;

the elastic sheet push rod is fixedly connected with the connecting block 24 and comprises a contact push rod 271 and a separation push rod 272;

the contact push rod 271 is disposed on one side of the trigger elastic piece 253 close to the second end 14a of the first guide rail, and the disengagement push rod 272 is disposed on one side of the trigger elastic piece 253 close to the first end 13a of the first guide rail; moreover, the distance between the contact push rod and the separation push rod 272 in the moving direction of the first moving block is greater than the thickness of the trigger elastic sheet 253;

the contact push rod 271 and the release push rod 272 can respectively abut against the trigger spring piece 253.

When the abutting end 252 is not in contact with the abutting surface 151, the abutting end 252 needs to be spaced from the abutting surface 151 by a sufficient distance, so as to avoid that the abutting end 252 mistakenly touches the abutting surface 151 during the moving process of the abutting end 252 with an excessively small spacing distance, which causes the lock outside the connecting block 24. When the whole abutting rod 25 is made of a rigid material, the stroke of the abutting end 252 of the abutting rod 25 rotating to the abutting surface 151 is synchronous with the stroke of the connecting block 24 driving the hinged end 251 to move, if the distance between the abutting end 252 and the abutting surface 151 is too large, a long moving stroke of the connecting block 24 relative to the first moving block 21 is needed to enable the abutting end 252 to abut on the abutting surface 151, the needed time is long, and the connecting block 24 may be locked untimely.

In this embodiment, the trigger spring 253 can be squeezed by the spring push rod, so that the trigger spring 253 is bent in different directions, when the moving stroke of the connecting block 24 is not changed, the rotating stroke of the abutting end 252 is accelerated, a sufficient safety distance can be kept before the abutting end 252 contacts the abutting surface 151, and when the abutting end 252 needs to abut against the abutting surface 151, the abutting end 252 can be rapidly rotated to abut against the abutting surface 151.

Specifically, when the connecting block 24 moves towards the first end 13a of the first guide rail relative to the first moving block 21, the contact push rod 271 fixed on the connecting block 24 contacts with the trigger elastic piece 253, and when the connecting block continues to move, the contact push rod 271 abuts against the trigger elastic piece 253 to enable the trigger elastic piece 253 to be pushed to rotate, the abutting rod 25 is limited by the first limit edge 32 to move, so that the abutting rod 25 adapts to the deformation of the trigger elastic piece 253 in a mode of accelerating rotation, and the abutting end 252 accelerates to rotate towards one side of the abutting surface 151 and abuts against the abutting surface 151. And the force of the deformed spring sheet being reset always abuts the abutting end 252 against the abutting surface 151, increasing the stability of the abutment.

When the strain spring 23 contracts, the disengagement plunger 272 pushes the trigger spring 253 in the opposite direction from the direction pushed by the contact plunger 271, and the trigger spring 253 deforms toward the second end 14a of the first rail, so that the contact end 252 of the contact lever 25 rapidly rotates toward the end away from the contact surface 151, and a large safety distance is provided between the contact end 252 and the contact surface 151.

Example 7

Referring to fig. 5 and fig. 7 to fig. 10, further, the limiting member is a limiting sliding sleeve 31, and the limiting sliding sleeve 31 is sleeved on the abutting rod 25 and is in sliding fit with the abutting rod 25;

the limit sliding sleeve 31 is hinged to the first moving block 21, so that the limit sliding sleeve 31 can rotate relative to the first moving block 21.

One side of the contact surface of the limiting sliding sleeve 31 and the abutting rod 25, which is close to the first end 13a of the first guide rail, is a first limiting edge 32, one side of the contact surface of the limiting sliding sleeve 31 and the abutting rod 25 is a second limiting edge 33, and the first limiting edge 32 and the second limiting edge 33 which are arranged in the limiting sliding sleeve 31 limit the moving direction of the abutting rod 25, so that the abutting rod 25 can only slide along the opening direction of the limiting sliding sleeve 31.

The limit sliding sleeve 31 is hinged to the first moving block 21, and when the connecting rod 25 rotates, the limit sliding sleeve 31 can rotate along with the connecting rod 25.

Example 8

2-4, further, the guide rail is provided with a V-shaped rail surface 16;

v-shaped grooves 221 are formed in the bottoms of the first moving block 21 and the second moving block 28, and the first moving block 21 and the second moving block 28 are in sliding fit with the V-shaped track surface 16 through the V-shaped grooves 221;

the guide rail further comprises a limiting plate 17, the limiting plate 17 is arranged on one side close to the V-shaped rail surface 16, and a moving space of a first moving block 21 and a second moving block 28 is formed between the limiting plate 17 and the V-shaped rail surface 16;

The matching of the V-shaped track surface 16 and the V-shaped groove 221 makes the clearance between the contact surfaces of the first moving block 21 and the second moving block 28 and the track small, and improves the smoothness of the moving mechanism in the moving process.

In some application environments, for example, when the scraper 40 used for shoveling the bottom of the manure pit 60 is dragged, some impurities may be splashed on the guide rail in daily use, and if a planar guide rail is adopted, the impurities may be accumulated on the guide rail, so that the smoothness of the movement of the moving block on the guide rail is reduced.

In this embodiment, the V-shaped rail surface 16 is used to reduce the accumulation of the foreign objects, and even if a small amount of foreign objects adhere to the V-shaped rail surface 16, the foreign objects on the V-shaped rail surface 16 can be pushed away and fall off the inclined surface of the V-shaped rail surface 16 when the V-shaped groove 221 moves relative to the V-shaped rail surface 16.

The first moving block and the second moving block are limited through the limiting surface, the first moving block and the second moving block are prevented from being separated from the V-shaped rail surface 16, when the functional component is a scraper, the bottom of the excrement groove needs to be shoveled, if the scraper is lifted upwards, a gap is formed between the scraper and the bottom of the excrement groove, excrement cannot be scraped completely, and one side, far away from the V-shaped rail surface, of the first moving block and the second moving block is limited, so that the scraper can be prevented from being lifted.

It should be noted that the first moving block 21 in the present embodiment includes the connecting block 24, and the first moving block 21 may be restricted by the surface of the connecting block 24 higher than the surface of the first moving block 21.

wherein, the two connecting bodies are respectively connected to the functional component connecting positions 56 of the first moving block 21 and the second moving block 28; wherein the shovelling end 41 is used for contacting the bottom of the manure pit 60.

The bottom of the manure groove 60 is cleaned, the labor intensity of workers is high, the equipment acquisition cost required for cleaning the bottom of the manure groove 60 by adopting the existing modes of a conveying belt and the like is high, and the manure groove is not suitable for small and medium-scale farms.

The large-span balanced manure shoveling device for the livestock shed provided by the embodiment can be used for installing two guide rails in parallel along two sides of the discharging direction of the manure groove 60, then the guide rails are respectively arranged on the first guide rail 11 and the second guide rail 12, the first moving block 21 and the second moving block 28 penetrate through the traction rope 34, and after two connectors of the scraping plate 40 are connected with the functional component connecting positions 56 on the first moving block 21 and the second moving block 28, the first moving block 21 and the second moving block 28 are connected into a whole and move synchronously.

The shoveling end 41 is in contact with the bottom of the dung trough 60, and when excrement accumulated at the bottom of the dung trough needs to be cleaned, the pulling end 36 of the pulling rope 34 is pulled to move the first moving block 21 and the second moving block 28 together, so that the excrement accumulated at the bottom of the dung trough is pushed to the outlet direction to clean the dung trough.

In this embodiment, the connector can be configured as a rotating shaft 42 or a non-circular insertion block, and the functional component connection site 56 is configured as a hole-shaped structure with a corresponding shape, so that the connector is inserted into the hole during installation. Or the corresponding positions of the connecting body and the moving block are provided with fixing holes and threaded holes, and the scraper 40 is fixed in a bolt connection mode.

the return pull rope 53 has a return fixed end 54 and a return pull end 55, and the return fixed end 54 is fixed at the second end 14b of the second guide rail;

the return traction end 55 sequentially passes through the fourth pulley 52 and the third pulley 51 and then is led out from the second end 14a of the first guide rail.

The return hauling rope 53 is used for hauling the scraper 40 in the direction opposite to the discharging direction, after the scraper 40 is hauled to the position of the discharging hole through the hauling rope 34, the return hauling rope 53 is pulled again to haul the scraper 40 from the position of the discharging hole to the end far away from the discharging hole for use, after excrement is accumulated at the bottom of the excrement groove, the hauling rope 34 is pulled again to shovel the excrement to the end of the discharging hole.

Example 12

Referring to fig. 12 and 13, further, a return strain spring 57 and a return connecting block 58 are further disposed on the first moving block 21;

wherein the length direction of the return strain spring 57 is the same as the guide rail; one side of the return strain spring 57, which is far away from the second tail end 14a of the first guide rail, is connected with the return moving block, and one side of the return strain spring 57, which is close to the second tail end 14a of the first guide rail, is connected with the return connecting block 58;

The embodiment is provided on the basis of the embodiment 11, and by the technical solution provided in the embodiment 11, the scraper 40 can be subjected to balanced traction, and at this time, if a force applied to the traction end 36 of the traction rope 34 is suddenly increased (for example, a machine is suddenly and quickly started in a traction manner, or a hand is intermittently and strongly dragged in a traction manner), the moving speed of the first moving block 21 close to the traction end 36 of the traction rope 34 may be suddenly increased, so that the moving mechanism connected to the scraper 40 is deflected, and a limit contact surface between the moving mechanism and the guide rail is twisted, so that the moving mechanism is subjected to a jerking phenomenon, and even is stuck to the guide rail.

In the technical solution provided in this embodiment, the third pulley 51 is connected to the first moving block 21 through the return connection block 58 and the return strain spring 57, when the traction force of the traction end 36 is suddenly increased by the applied force, the return strain spring 57 on the first moving block 21 is stretched, and the distance between the third pulley 51 and the first moving block 21 is lengthened, so as to compensate for the deflection caused by the side of the first moving block 21 being faster than the moving speed of the second moving block 28, and avoid the jerk and the jam on the guide rail when the moving mechanism is pulled.

When the acceleration applied to the pulling end 36 is reduced, the return strain spring 57 returns from the stretched state to the contracted state, and the first moving block 21 and the second moving block 28 return to the balanced movement.

Springs with different specifications can be set as the return strain springs 57 according to different application scenes, and the critical tension of deformation of the specific return strain springs 57 during stretching is larger than the tension required for driving the return strain springs 57 to move during working, so that the return strain springs 57 cannot be stretched during normal traction.

In some embodiments, the technical solutions described in embodiments 3 to 7 may be added to the first moving block 21, and the scraper 40 is locked to fix the return connecting block 58, so as to release the locking of the moving mechanism during the continuous pulling.
