Detailed Description

The foregoing and other technical matters, features and effects of the present invention will be apparent from the following detailed description of the embodiments with reference to the accompanying drawings, in which reference is made to the accompanying drawings.

The embodiment provides an intelligent and accurate fertilizing and seeding machine for wheat, as shown in the attached drawings 1-9, which comprises a frame body, a storage hopper is arranged at the highest point of the frame body, the middle part of the storage hopper is divided into two parts by a separating mechanism, a fertilizer placing port is far away from a conveying hopper, the other part of the storage hopper is a seed placing port, the seed placing port can freely fall to a main conveying rod when the machine runs, the main conveying rod is a core point of the scheme, the main conveying rod is provided with a seed conveying groove for conveying seeds and a fertilizer conveying groove for conveying fertilizer (the seed conveying groove and the fertilizer conveying groove are not communicated, the stored seeds and the fertilizer are not interfered with each other, the fertilizer conveying groove is moved to the outlet end of an inlet baffle and an outlet baffle by a rotation angle, when the fertilizer conveying groove is conveyed to the outlet end of the inlet baffle and the outlet baffle, a proportional control rod can also move a filled metering groove to the position under the inlet baffle and the outlet baffle, the fertilizer in the filling metering groove automatically falls onto the fertilizer conveying groove of the main conveying rod after one end of pause, then the fertilizer and the seeds fall into the blanking mechanism after the next rotation of the main conveying rod, one group of seeds and the fertilizer fall out after the main conveying rod rotates, the quantitative control proportion effect is achieved, the quantification introduced here is described, because the machinery for planting the land belongs to large-scale machinery, the coarser the machinery is, the more practical the machinery is, the more accurate the data is, the planting is not like a scientific research experiment, the data needs to be accurate, the better effect is achieved, the research efficiency of planting instruments is improved, the smaller deviation of the data belongs to the normal phenomenon, the quantification introduced here is the quantification which must be expressed through the accurate numerical value, and the smaller deviation of the data is generated in the scheme, the invention belongs to the normal phenomenon, and the invention solves the problems that the random proportion of the fertilizing amount and the seeding amount has larger data deviation, which needs to be distinguished, a transfer case is fixed on a frame body through long rods at two sides, the structure in the transfer case is the main realization structure of the scheme, two sides of the transfer case are provided with slots for the transfer case, a main conveying rod, a proportion control rod and a poking rod to rotate, which is convenient and stable to rotate, how the three groups of rods drive to rotate in the next section can be specifically introduced, the main conveying rod aims to convey fertilizer and seeds simultaneously, the poking rod aims to prevent the main conveying rod from blocking the seeds beside the main conveying rod during rotation, the seeds are poked in one direction by rotating all the time, the framework of the poking rod is steel or aluminum alloy, the wheels of the poking rod are of a sponge or brush structure, and the first cylinder and the second cylinder are preferably made of transparent plastics, more convenient depth viewing) is another innovative point of the present invention, the proportional control rod needs to be used in comparison with the proportional comparison mechanism, which will be explained in detail in the next section, a slidable insertion rod is arranged inside the proportional control rod, the insertion rod can slide on the proportional control rod, the width of the metering slot can be adjusted during the sliding process of the insertion rod, (because the insertion rod slides on the proportional control rod, in order to prevent the insertion rod from being able to enter the proportional control rod from the slide way when the width of the metering slot is changed, we set the insertion rod as an inner rod, and then set the insertion rod as a long strip whose periphery is matched with the slide way, the outer diameter of the long strip is also the outer diameter of the proportional control rod, so that no matter how the insertion rod slides, a gap is left on the outer diameter of the middle part of the proportional control rod, and only gaps are left on two sides, but both sides are blocked by the transfer case, so the fertilizer can not reach the inside of the proportion control rod), namely, the volume of the fertilizer needing to be proportioned is finally determined, the mass of the fertilizer can be roughly calculated according to the volume of the fertilizer, the mass of the fertilizer (the density is a known quantity) is calculated by multiplying the volume by the density, how to roughly adjust the mass ratio of each group of fertilizer to the seeds is explained in the next section, a first baffle, a second baffle and an inlet-outlet baffle are introduced, the first baffle prevents the seeds from entering the seed conveying groove and being separated from the seed conveying groove in the rotating process, the transfer case, the first baffle and the inlet-outlet baffle form a cavity, the seeds and the fertilizer can not enter the cavity, the reason that the seeds can not enter the cavity is blocked by the first baffle, the reason that the fertilizer can not enter the fertilizer can be blocked by one end of the inserting rod, and the fertilizer can only enter the inlet-outlet baffle, then enters the cavity from the metering slot on the proportional control rod, which is only the situation without the insertion rod, the port can be blocked under the situation with the insertion rod, the fertilizer can not enter the cavity, the insertion rod can not be separated from the proportional control rod, the cavity is designed to facilitate one end of the insertion rod to have a movable space, the insertion rod can conveniently slide to adjust the size of the metering slot, the size of the cylinder of the main control rod is introduced, the size of the cylinder of the main control rod is approximate to twice of the size of the cylinder of the proportional control rod but does not reach twice, the width of the cylinder of the main control rod is the internal width of the transfer box, which is the reason that the main control rod can convey the fertilizer and seeds, so one side of the proportional control rod has one time of movable space, namely the reason that the insertion rod can be arranged, one of the transmission blades is driven by the output motor, the setting of transmission leaf can prevent that seed or fertilizer from piling up in one end, and output motor belongs to prior art and does not carry out the introduction one by one, because the transport position of fertilizer and seed is opposite, so two transmission leaf rotation direction are opposite.

As shown in fig. 9-13, the present invention comprises a ratio comparison mechanism, which is a comparison mechanism before the present invention is practical, the present invention needs to empty fertilizer and seeds in a storage hopper before operation, (fertilizer and fertilizer sowing needs to spread fertilizer and spread seeds at the same time, and is not mixed sowing, the present invention provides a gap motion mechanism for seed and fertilizer sowing, which can stagger wheat and fertilizer, and extend at the tail end of the second baffle, so that the staggered group of wheat and fertilizer can only fall down to wheat, the next group can only fall down to fertilizer by ninety degrees, and there is a time to stop, during which the machine itself is walking, that is, there is a distance between the just fallen seeds and the fertilizer to fall, so the present scheme is that wheat and fertilizer are not mixed in one point for planting, distance difference exists between the seeds, but the distance between each group of seeds is not changed much, and the distance between each group of fertilizers is not changed much), the invention needs to compare before operation, we know that the proportional relation of fertilizers and seeds in life is weight proportion, and supposing that the machine needs two jin of seeds and one jin of fertilizers to be blended, we obtain the blending proportion of 2: 1, the distance from a first cylinder of seeds to the center is adjusted to be C, a second cylinder of fertilizer is adjusted to be 2C only by a proportion comparison mechanism, the mass of the seeds in the first cylinder is twice of that of the fertilizer in the second cylinder according to the lever principle, the seeds used at this time are only required to be filled in the first cylinder, namely the mass of the seeds discharged at each time (because the internal pattern of the first cylinder in the scheme is consistent with the pattern of a fertilizer conveying groove and the height is also consistent, namely the volume of the first cylinder is the volume of the seed conveying groove), the proportion rod balance is only required to add half of the weight of the seeds discharged at each time into the second metering cylinder, and the proportion rod balance only needs to observe scale lines on the second metering cylinder (because the internal pattern of the second cylinder and the pattern of the metering groove are constant), namely the height, namely the width of the splicing rod (the splicing rod is horizontally placed), the position of the inserting rod, namely the width of the metering groove, can be adjusted step by step only by twisting the threaded control rod at one side of the frame body, a side frame is introduced, the side frame is arranged at one side of the frame body and is in threaded connection with the threaded control rod, the threaded control rod can rotate inwards or outwards when the threaded control rod is twisted, the effect of controlling the inserting rod to slide is achieved, the fixing effect is achieved without twisting, the thread has a locking function (one side of the threaded control rod is provided with an anti-falling groove, one side of the inserting rod is provided with an anti-falling block, the shape of the anti-falling block is spherical, namely when the threaded control rod moves, the inserting rod is driven to move, the stopping is to drive the inserting column to stop, but the rotating of the inserting rod is not influenced), the data can be conveniently obtained from the second cylinders and then adjusted on the side frames, the inserting rod is also provided with a marking block for convenient marking, how a main conveying rod, a proportion control rod and a poke rod are linked is described, a proportion comparison mechanism is preferably made of light materials and can reduce the measurement error, the proportion control rod and the poke rod are driven to rotate through the main conveying rod, the main conveying rod and the proportion control rod are driven by a transmission mechanism capable of rotating in different directions, the transmission mechanism in different directions is formed by meshing two same gears, namely, the transmission mechanism in different directions can drive the proportion control rod to rotate in opposite directions when the main conveying rod rotates, the main conveying rod and the poke rod are driven by a transmission mechanism in the same direction, the transmission mechanism in the same direction is formed by a belt and a belt pulley, the poke rod can be driven to rotate in the same direction when the main conveying rod rotates, the main control rod is intermittently rotated (which will be described in the next section), so the proportion control rod and the poking wheel are intermittently rotated, the invention only improves the proportion of fertilizer and seeds, but not improves other parts of the sowing mechanism, if the scheme is that some instruments do not belong to normal instruments of the sowing machine, the invention is not specifically described in the specification, and does not belong to the protection range of the scheme, the invention is not used for the normal instruments (such as the tillage mechanism of the scheme), the blanking mechanism is lapped on a rod at one side of the traveling wheel in the scheme, one side of the traveling wheel is provided with a rotating shaft, the shaft is not the rod lapped by the blanking mechanism, but is rotatably arranged in the lapping rod, the scheme is provided with a conveying hopper, the conveying hopper is also arranged at a middle part in a separated way, one end is used for storing seeds and the other end is used for placing fertilizer, and the material is automatically conveyed to the storing hopper when the frame body travels, belt conveying mechanism is exactly band conveyer, but this drives through the walking wheel, and the walking wheel can drive band conveyer's bottom axle at the in-process of walking and rotate, reaches the effect that drives belt drive, and the quantity of long belt is two, and that is exactly both sides drive respectively, and band conveying mechanism belongs to prior art field so and does not carry out the introduction one by one.

As shown in fig. 14-20, including a speed change mechanism, since many speed change mechanisms are available on the market, the speed change mechanism is described last, the core of the speed change mechanism is a speed trigger mechanism, the speed change mechanism is described in detail herein, the speed change mechanism includes a gear shifting mechanism, a speed trigger mechanism and an electric control mechanism, a transmission rod and an output wheel are fixedly arranged, the transmission rod is provided with a first gear 35, a second gear 36 and a third gear 37, the speed trigger mechanism includes a speed dial 38, an inner control dial 39, a trigger block 40 and a trigger dial 41, one side of the speed dial 38 is fixedly arranged with the speed wheel 30, the trigger block 40 can slide on the inner control dial 39 and the speed dial 38, and one side is provided with a spring return, when the speed is too high, the trigger block 40 can generate a centrifugal force far away from the center of the speed dial 38, the far distance of the trigger block 40 can be converted into a trigger signal, the trigger disc 41 is provided with two groups of pressable press rings 42, the two groups of press rings 42 can be gradually and sequentially pressed by the trigger block 40 when the trigger block 40 is far away from the center of a circle to generate an electric signal, the condition that the press rings 42 generate the electric signal is that the inner spring presses for a certain distance to generate the electric signal, once the electric signal is generated, the electric control mechanism can be controlled to stretch for one end distance, the second press ring 42 is triggered to continue to stretch for one end distance, when the walking speed of the walking wheel is reduced, the centrifugal force is smaller than the spring force to enable the trigger block 40 to move back and forth, the effect of extruding the second press ring 42 (namely, the press ring 42 on the outer ring) again to enable the electric control mechanism to stretch out for one end distance is achieved, the first press ring 42 (namely, the press ring 42 on the inner ring) is extruded again to enable the electric control mechanism to stretch out for one end distance, and the adjustment is directly carried out through the electric control mechanism, the speed trigger mechanism only generates an electric signal in the triggering process and mainly adjusts the speed trigger mechanism by an electric control mechanism, the electric control mechanism is an electric push rod, the point that the electric signal is generated to control the electric push rod is not the innovation point of the scheme, but the prior art is utilized, the scheme does not improve the point, so the scheme is not carefully introduced, the outer surface of the extending end of the electric control mechanism is sleeved on the inner arc of the middle matching rod, namely the extending end controls the extension without influencing the rotation of the middle matching rod, the middle matching rod is provided with a fourth gear 43, a fifth gear 44 and a sixth gear 45, the intermittent motion mechanism is arranged on one side of the frame body, one side of the special rotating wheel is also provided with a seventh gear 46, one side of the frame body is provided with a communicating gear 47, the communicating gear 47 rotates on the surface of the frame body, one end inside the communicating gear 47 is meshed with the seventh gear 46, one end of the outer part is meshed with the sixth gear 45, when the speed of the travelling wheel is increased and the condition that the trigger block 40 moves is reached, the trigger pressing ring 42 is extruded to enable the electric control mechanism to operate and retract the third gear 37 and the sixth gear 45 to be meshed before one step, the fifth gear 44 is meshed with the second gear 36 after the retraction, the third gear 37 and the sixth gear 45 are disengaged to achieve first-stage adjustment, when the second pressing ring 42 is pressed, the fifth gear 44 is meshed with the second gear 36 to be disengaged, the first gear 35 is meshed with the fourth gear 43 to achieve second-stage adjustment, the sixth gear 45 and the seventh gear 46 are always in a meshed state in the two processes, the first-stage adjustment and the second-stage adjustment can reduce the stopping time of the rotating gap of the main output shaft, the second-stage adjustment is shorter than the stopping time of the first-stage gap, the effect that the traveling speed of the auxiliary wheel is faster is achieved, and the rotating direction of the main conveying rod is considered in the design of the scheme, that is, the rotation direction of the main conveying rod is the same as that of the travelling wheel, the hidden belt is arranged in the hollow parts at the two sides of the auxiliary wheel, and a group of belt pulleys are arranged in the
