Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a fertilizing device for a wheat breeding spot-seeder and a use method thereof. Background Art

[0002] During the wheat sowing process, it is necessary to continuously replenish fertilizer from the upper hopper of the seeder to the lower hopper. Due to the change in the speed of the seeder, the speed of fertilizing cannot keep up with the change in the sowing speed. When the sowing speed is fast, the fertilizer replenishment cannot keep up with the fertilizer spreading, resulting in a lack of fertilizer in the lower hopper. When the sowing speed is slow, the fertilizer in the lower hopper is squeezed and overflowed. A device is needed to solve the above problems.

[0003] The patent with application number 202210787300.3 discloses a fertilizing device for a wheat breeding spot seeder and an operating method. The patent includes a frame, a rack, a double gear, a speed regulating device, and an adjusting device. The speed regulating device includes a speed regulating seat, a movable frame, a friction ring, and a conical friction wheel. The adjusting device includes a sliding sleeve, a rotating sleeve, and a flying ball. The frame has a gear shaft in the middle of the front, a No. 1 bevel gear hole on the left side of the gear shaft, an intermediate shaft hole on the right side of the gear shaft, a slide groove on the right side of the intermediate shaft hole, an upper hopper in the middle of the frame, an upper hopper hole in the left and right directions at the lower part of the upper hopper, a lower hopper on the rear side of the frame, two lower hopper holes symmetrically located on the upper part of the lower hopper, four axle holes at the lower part of the frame, a rack slider on the front side of the rack, a slot on the upper part of the rack, a No. 1 gear at the lower part of the double gear, a No. 2 gear at the upper part of the double gear, and a double gear hole in the middle of the double gear. This patent has the following deficiencies: the conveyor belt still runs in reverse during reversing, and after reversing, the conveyor belt needs to re-input the fertilizer into the lower hopper. During this process, no fertilizer is temporarily transported to the lower hopper; when the fertilizer falls from the conveyor belt into the lower hopper, it accumulates in one place and cannot be evenly dropped. Summary of the invention

[0004] The object of the present invention is to provide a fertilizing device for a wheat breeding spot-seeding device and a use method thereof, so as to solve the problems existing in the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A fertilizing device for a wheat breeding spot-seeding device comprises a frame, an upper hopper and a lower hopper are installed on the frame, an axle is provided at the bottom end of the frame, a feeding valve is installed at the discharge end of the upper hopper, the discharge end of the upper hopper is connected to the feed end of the lower hopper through a pipe chain conveyor, a flow limiting tube is sleeved on the pipe chain conveyor, the flow limiting tube is connected to the lower hopper through an electric cylinder, a first bevel gear is installed on the axle, a vertical shaft is connected to the power input shaft of the pipe chain conveyor through a sprocket structure, a second bevel gear and a plurality of shifting rods are installed on the vertical shaft, the first bevel gear is meshed with the second bevel gear, a plurality of arch breaking devices are fixed to the side of the lower hopper, the arch breaking device is provided with a plurality of vibrating rods, and one end of the vibrating rod is located on the rotation path of the shifting rod.

[0009] Furthermore, the vibration rod is made of a square rod.

[0010] Furthermore, the tube chain conveyor has two discharge ends, one of which is located above the feed end of the upper hopper and is equipped with an electric valve, and the other of which is located above the feed end of the lower hopper.

[0011] Furthermore, the flow limiting tube is sleeved on the discharge end of the tube chain conveyor located above the lower hopper. A number of strip holes are provided on the discharge end of the tube chain conveyor located above the lower hopper and on the flow limiting tube. The strip holes on the tube chain conveyor and the flow limiting tube are both facing the feed end of the lower hopper. The distance between the strip holes on the tube chain conveyor and the flow limiting tube is greater than the length of the strip holes.

[0012] Furthermore, a vertical plate is welded on the current limiting tube, one end of the electric cylinder is fixed on the lower hopper, and the other end of the electric cylinder is fixed on the vertical plate.

[0021] 3. The amount of fertilizer applied is controlled to match the sowing speed through the current limiting tube, electric cylinder and speed sensor.

[0022] 4. When the agricultural vehicle is reversing, the one-way bearing idles, the vertical shaft stops rotating, the tube chain conveyor stops running, and the electric cylinder retracts so that the current limiting tube blocks the strip hole on the tube chain conveyor, thereby stopping loading.

[0023] 5. After sowing, there may be fertilizer left in the tube chain conveyor. At this time, the circulating operation characteristics of the tube chain conveyor can be used to return the fertilizer to the upper hopper to prevent the fertilizer from getting damp in the tube chain conveyor and hardening on the material tray of the tube chain conveyor.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Embodiment 1:

[0032] like Figure 1-5 As shown, a fertilizing device for a wheat breeding spot-seeding device comprises a frame 1, an upper hopper 2 and a lower hopper 3 are installed on the frame 1, an axle 4 is provided at the bottom end of the frame 1, a feeding valve 5 is installed at the discharge end of the upper hopper 2, the discharge end of the upper hopper 2 is connected to the feed end of the lower hopper 3 through a pipe chain conveyor 24, a flow limiting tube 6 is sleeved on the pipe chain conveyor 24, the flow limiting tube 6 is connected to the lower hopper 3 through an electric cylinder 7, a first bevel gear 8 is installed on the axle 4, a vertical shaft 9 is connected to the front end bearing of the frame 1, the vertical shaft 9 is connected to the power input shaft of the pipe chain conveyor 24 through a sprocket structure 10, a second bevel gear 11 and a plurality of shifting rods 12 are installed on the vertical shaft 9, the first bevel gear 8 is meshed with the second bevel gear 11, a plurality of arch breaking devices 13 are fixed to the side of the lower hopper 3, the arch breaking device 13 is provided with a plurality of vibrating rods 14, and one end of the vibrating rod 14 is located on the rotation path of the shifting rod 12.

[0033] A one-way bearing 15 is installed at the bottom end of the vertical shaft 9, and the second bevel gear 11 is fixed on the outer ring of the one-way bearing 15. A speed sensor 16 is installed at the bottom end of the front side of the frame 1 near the vertical shaft 9, and the detection end of the speed sensor 16 faces the vertical shaft 9. A magnet 17 is fixed at a position corresponding to the speed sensor 16 on the vertical shaft 9. The speed sensor 16 is a prior art and is often used to detect the speed of gears and shafts.

[0034] The arch breaking device 13 includes a U-shaped frame 18, the U-shaped frame 18 opens toward the side of the upper hopper 2 and is welded to the upper hopper 2, one end of the vibrating rod 14 passes through the U-shaped frame 18 and is welded with a vibrating block 19, the vibrating block 19 abuts against the side of the upper hopper 2, a spring 20 is sleeved on the vibrating rod 14 between the vibrating block 19 and the U-shaped frame 18, the other end of the vibrating rod 14 is L-shaped, one end of the L-shaped vibrating rod 14 faces the vertical axis 9 and is located on the rotation path of the lever 12. Sometimes when the fertilizer is damp or has poor fluidity, it is easy to bridge in the upper hopper 2, causing it to be unable to fall. The vibrating rod 14 is moved outward by the lever 12, and the spring 20 is compressed. When the lever 12 continues to rotate and separates from the vibrating rod 14, the vibrating rod 14 is reset under the elastic force of the spring 20, and the vibrating block 19 hits the outer wall of the upper hopper 2, thereby breaking the arch of the fertilizer in the upper hopper 2 and causing it to fall.

[0035] The vibration rod 14 is made of a square rod, which can prevent the vibration rod 14 from rotating. If the vibration rod 14 rotates, one L-shaped end of the vibration rod 14 will not face the vertical axis 9, and the lever 12 will not be able to move the vibration rod 14, thereby failing to achieve the purpose of breaking the arch.

[0036] The tube chain conveyor 24 has two discharge ends, one of which is located above the feed end of the upper hopper 2 and is equipped with an electric valve 21, and the other of which is located above the feed end of the lower hopper 3. After sowing, fertilizer may remain in the tube chain conveyor 24. At this time, the circulating operation characteristics of the tube chain conveyor 24 can be used to return the fertilizer to the upper hopper 2 to prevent the fertilizer from getting damp in the tube chain conveyor 24 and hardening on the material tray of the tube chain conveyor 24.

[0037] The flow-limiting tube 6 is sleeved on the discharge end of the tube chain conveyor 24 located above the lower hopper 3. A plurality of strip holes 22 are provided on the discharge end of the tube chain conveyor 24 located above the lower hopper 3 and the flow-limiting tube 6. The strip holes 22 on the tube chain conveyor 24 and the flow-limiting tube 6 are both facing the feed end of the lower hopper 3. The distance between the strip holes 22 on the tube chain conveyor 24 and the flow-limiting tube 6 is greater than the length of the strip holes 22. When the strip holes 22 on the tube chain conveyor 24 and the flow-limiting tube 6 completely overlap, the amount of fertilizer falling is the largest. When the flow-limiting tube 6 blocks the strip holes 22 on the tube chain conveyor 24, the amount of fertilizer falling is zero. When the strip holes 22 on the tube chain conveyor 24 and the flow-limiting tube 6 partially overlap, the amount of fertilizer falling is related to the area of ​​overlap of the strip holes 22.

[0038] When the running speed of the seed drill becomes faster, the feeding speed increases. If the discharge end of the tube chain conveyor 24 remains unchanged, part of the fertilizer will be returned to the upper hopper 2 before it can fall. Therefore, the speed of the vertical shaft 9 is detected by the speed sensor 16. When the speed increases, the overlapping area of ​​the bar holes 22 increases, and the fertilizer falls evenly from each bar hole 22 and the feeding amount increases; on the contrary, the overlapping area of ​​the bar holes 22 decreases, and the fertilizer feeding amount decreases, so that the fertilizer feeding amount matches the sowing speed.

[0039] A vertical plate 23 is welded on the current limiting tube 6 , one end of the electric cylinder 7 is fixed on the lower hopper 3 , and the other end of the electric cylinder 7 is fixed on the vertical plate 23 .

[0040] Embodiment 2:

[0041] This embodiment provides a method for using a fertilizing device for a wheat breeding spot-seeding device, and the method steps are implemented based on Example 1.

[0042] A method for using a fertilizing device for a wheat breeding spot-seeder comprises the following steps:

[0043] (1) The speed sensor 16 is electrically connected to the control system of the electric cylinder 7, the extension length of the electric cylinder 7 at different speeds is set, the frame 1 is connected to the agricultural vehicle, and the fertilizer is placed in the upper hopper 2. The electric cylinder 7 can be equipped with a PLC control system and can be programmed by PLC. The electric cylinder 7 is a prior art, which is electrically connected to the speed sensor 16, and the extension length of the electric cylinder 7 is controlled by the speed.

[0044] (2) After arriving at the operation area, the agricultural vehicle is driven to perform on-demand seeding operations. During the movement of the agricultural vehicle, the axle 4 drives the tube chain conveyor 24 to operate, and the fertilizer in the upper hopper 2 is transported to the upper part of the lower hopper 3 of the tube chain conveyor 24. The speed sensor 16 detects the speed of the vertical shaft 9, and the electric cylinder 7 extends a certain length according to the speed. The fertilizer falls from the overlapping part of the tube chain conveyor 24 and the strip hole 22 of the flow limiting tube 6 into the lower hopper 3, and at the same time, the arch breaking device 13 vibrates the upper hopper 2. The tube chain conveyor 24 above the lower hopper 3 is horizontal at the feeding end of the lower hopper 3. Since the amount of fertilizer falling from the strip holes 22 is limited, the fertilizer cannot fall completely from one strip hole 22 of the tube chain conveyor 24, but only a small part falls, and the remaining part continues to move forward and passes through each strip hole 22 in turn, so that fertilizer falls from each strip hole 22. Therefore, the fertilizer is transported from one end of the lower hopper 3 to the other end, and falls from different positions of the lower hopper 3, so as to achieve uniform fertilization, and the remaining fertilizer that has not fallen is rotated to continue fertilization.

[0045] The seed drill is usually driven by a tractor or other agricultural vehicle, and the tractor generally has a lifting function. When driving on the road, there is no need to apply fertilizer, so the front end of the frame 1 is lifted, so that the front wheel does not touch the ground, so the front axle 4 does not rotate, and the tube chain conveyor 24 is not driven to run. After arriving at the working area, the front end of the frame 1 is lowered, the front wheel touches the ground, and the seed drill can drive the tube chain conveyor 24 to load materials when moving forward.

[0046] (3) When the agricultural vehicle is reversing, the one-way bearing 15 idles, the vertical shaft 9 stops rotating, the tube chain conveyor 24 stops running, and the electric cylinder 7 retracts so that the current limiting tube 6 blocks the strip hole 22 on the tube chain conveyor 24, thereby stopping the feeding.

[0047] When the seed drill is performing sowing operations, it is sometimes necessary to reverse. At this time, there is no need to run the tube chain conveyor 24 (the tube chain conveyor 24 has the characteristic of circulating operation, and fertilization can be carried out even if it is reversed). The one-way bearing 15 can only be driven in one direction and idle in the other direction. The vertical shaft 9 does not rotate when reversing, thereby avoiding fertilization when reversing.

[0048] (4) After the on-demand seeding operation is completed, the electric cylinder 7 is controlled to retract, so that the flow-limiting tube 6 blocks the strip hole 22 on the tube chain conveyor 24 to stop feeding, the electric valve 21 is opened, and the feeding valve 5 is closed, so that the fertilizer in the tube chain conveyor 24 returns to the feeding hopper 2. Of course, it is also necessary to lift the front end of the frame 1 by a tractor to facilitate the on-demand seeding machine to go on the road.

[0049] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should all fall within the scope of protection of the present invention.

[0050] The techniques, shapes, and structural parts not described in detail in the present invention are all well-known techniques.
