[0004] The aforementioned soybean planter cannot accurately control the spacing between planting holes, resulting in sparse and uneven planting density, thus failing to maximize soybean yield. Summary of the Invention

[0005] The purpose of this invention is to provide a soybean planting device and method to solve the problem mentioned in the background art that existing planters cannot accurately control the spacing between planting holes, thus preventing the maximization of soybean yield. To achieve the above objective, this invention provides the following technical solution:

The stop is adjustablely fixedly connected to the mounting plate.

[0008] Preferably, the stop includes an upper slider and a lower slider, which are slidably connected in a strip-shaped through hole in the mounting plate, and are pressed onto the mounting plate by bolts.

[0009] Preferably, the feeding mechanism includes a first mounting frame, two first mounting frames are fixedly connected in parallel to a mounting plate, a ring is fixedly connected to the first mounting frame, two end caps are rotatably connected in the ring, a rotating sleeve is fixedly connected between the end caps, a rotating disk is fixedly connected to the rotating sleeve, a plurality of receiving grooves are evenly opened on the rotating disk, a second mounting frame is fixedly connected to the first mounting frame, a hopper is fixedly connected to the second mounting frame, and the lower end of the hopper is in contact with the ring;

[0010] The rotating sleeve is connected to the rotating shaft three via belt drive assembly two. The rotating shaft three is rotatably connected to the mounting base three. The mounting base three is fixedly connected to the bottom plate of the mounting plate. A gear two is fixedly connected to the rotating shaft three. The gear two meshes with a rack two. The rack two is fixedly connected to a rack one.

[0011] A slider is slidably connected in the receiving groove. The slider is hinged to one end of the connecting rod. The other end of the connecting rod is hinged to a nut. The nut is screwed onto a lead screw. The lead screw is rotatably connected to a rotating sleeve. The lead screw is also rotatably connected to a mounting bracket three. The mounting bracket three is fixedly connected to a mounting plate.

[0012] Preferably, the acupuncture mechanism includes a square tube, which is slidably connected to a mounting plate. A tension spring connects the square tube to the mounting plate. A limiting protrusion is also provided on the square tube. A lifting rod is fixedly connected in the square tube, and a handle is fixedly connected to the lifting rod.

[0013] The lower end of the square tube is rotatably connected to four evenly arranged soil-removing plates. The inner wall of the soil-removing plate is hinged to one end of the second connecting rod. The other end of the second connecting rod is hinged to the connecting block. A connecting rod is fixedly connected to the connecting block. The connecting rod is slidably connected to the lifting rod. A second handle is fixedly connected to the upper end of the connecting rod. A second return spring is provided between the second handle and the first handle.

[0014] Preferably, the unlocking mechanism includes guide blocks, four of which are evenly arranged on the bottom surface of the mounting plate. An L-shaped plate is slidably connected to the guide block, and a top rod is fixedly connected to the L-shaped plate. The lower end of the top rod abuts against one end of a rotating rod. The rotating rod is rotatably connected to a fourth mounting base, which is fixedly connected to the bottom surface of the mounting plate. The other end of the rotating rod is hinged to one end of a third connecting rod, and the other end of the third connecting rod is hinged to a square tube.

[0015] Preferably, the conveying pipe is connected between the circular ring and the square pipe.

[0016] A soybean cultivation method using a soybean cultivation device includes the following steps:

[0017] S1. Preparation: Pour the soybean seeds to be planted into the hopper, then rotate the screw to move the slider to the desired position in the receiving groove, then loosen the bolt, adjust the stop block to the appropriate position, and then tighten the bolt to fix it.

[0018] S2. Positioning and unloading: Grab the handle and lift the rear end of the mounting plate to make the support leg leave the ground. Then push the device forward. When the device moves forward, the wheel rotates, which drives the rotating shaft 1 that is fixed to it to rotate. The rotating shaft 1 drives the rotating shaft 2 to rotate through the belt drive assembly 1. The rotating shaft 2 causes the rack 1 to slide on the L-shaped plate through the gear 1. When the rack 1 moves to the stop, it is blocked, thus preventing the device from moving forward.

[0019] During this process, rack 2, which is fixed to rack 1, moves synchronously and drives gear 2, which meshes with it, to rotate at a certain angle. Rotating shaft 3, which is fixed to gear 2, drives rotating sleeve to rotate at a certain angle through belt drive assembly 2. Rotating sleeve drives rotating disk fixed to it to rotate, so that soybean seeds in the receiving groove at the lower end of the ring enter the square tube through the transport pipe.

[0020] S3, Hole Making, Sowing and Unlocking: Grab handle one and place the support leg on the ground. Then press down handle one to insert the soil-pulling plate at the bottom of the square tube into the ground to a certain depth. Then keep handle one still and pinch handle two upward. Handle two moves the connecting block upward through the connecting rod. The connecting block moves the soil-pulling plate open through connecting rod two to pry open the soil and let the soybean seeds in the square tube fall into the hole. Then release handle one and handle two to make them automatically reset.

[0021] When the square tube moves downward, the rotating rod rotates through the connecting rod three. The rotation of the rotating rod drives the push rod that is in contact with it to move upward. The push rod drives the L-shaped plate that is fixed to it to move upward, thereby causing the rack one to disengage from the gear one. After disengagement, the rack one automatically resets under the action of the return spring one. When the square tube resets, the L-shaped plate and the rack one reset at the same time, and the device can continue to move forward.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In this invention, the hole spacing locking mechanism allows the device to automatically lock after advancing a certain distance, thereby determining the position of hole drilling and sowing, ensuring that the spacing between planted soybeans is basically consistent. At the same time, the hole spacing can also be adjusted by adjusting the position of the stop block, thereby adjusting the planting density of soybeans to the optimal condition, thereby increasing the yield.

[0024] 2. In this invention, the feeding mechanism automatically separates a certain number of soybean seeds and feeds them into the hole-drilling mechanism during the device's forward movement, ensuring that the number of soybeans sown each time is roughly the same. This eliminates the need for people to control the number of soybeans each time they sow, and the number of soybean seeds separated at one time can be controlled by rotating the screw to adjust the position of the slider. This makes the invention more versatile.

[0025] 3. In this invention, the trolley eliminates the need to lift the entire device for movement; instead, the trolley is pushed forward, reducing the burden on workers and making it easier to use. Attached Figure Description

A first gear 204 is fixedly connected to the second rotating shaft 202. The first gear 204 meshes with a first rack 205. The first rack 205 is slidably connected to an L-shaped plate 206. A return spring 207 is connected between the first rack 205 and the L-shaped plate 206. A stop block 208 is provided in the forward direction of the first rack 205. The stop block 208 is adjustablely fixedly connected to the mounting plate 101.

[0039] In this embodiment, the stop block 208 includes an upper slider 209 and a lower slider 210. The upper slider 209 and the lower slider 210 are slidably connected in the strip-shaped through hole 211 opened on the mounting plate 101. The upper slider 209 and the lower slider 210 are pressed onto the mounting plate 101 by bolts 212.

[0040] In this embodiment, the position of the stop block 208 can be adjusted in the strip-shaped through hole 211, so that the rack 205 will be blocked by the stop block 208 after moving different distances and the device will not be able to move forward. This allows the planting hole spacing to be adjusted by adjusting the position of the stop block 208.

[0041] In this embodiment, the feeding mechanism 3 includes a first mounting frame 301, two first mounting frames 301 are fixedly connected in parallel to the mounting plate 101, a ring 302 is fixedly connected to the first mounting frame 301, two end caps 303 are rotatably connected in the ring 302, a rotating sleeve 304 is fixedly connected between the end caps 303, a rotating disk 305 is fixedly connected to the rotating sleeve 304, a plurality of receiving grooves 306 are evenly opened on the rotating disk 305, a second mounting frame 307 is fixedly connected to the first mounting frame 301, a hopper 308 is fixedly connected to the second mounting frame 307, and the lower end of the hopper 308 is in contact with the ring 302;

The mounting bracket 318 is fixedly connected to the mounting plate 101.

[0044] In this embodiment, both the upper and lower ends of the ring 302 have openings for soybean seeds to pass through.

[0045] In this embodiment, the gear 312 rotates at a certain angle under the drive of the rack 313, and the rotating disk 305 connected to the gear 312 rotates at the same angle as the included angle between the two adjacent receiving grooves 306.

[0046] In this embodiment, the position of the slider 314 in the receiving groove 306 can be determined by the position of the nut 316 on the lead screw 317, and the position of the nut 316 can be adjusted by rotating the lead screw 317. The different positions of the slider 314 result in different numbers of soybean seeds that can be contained in the receiving groove 306. Thus, by rotating the lead screw 317, the number of soybean seeds contained in the receiving groove 306 can be changed, achieving different numbers of seeds sown at a time.

[0047] In this embodiment, the acupuncture mechanism 4 includes a square tube 401, which is slidably connected to the mounting plate 101. A tension spring 402 is connected between the square tube 401 and the mounting plate 101. A limiting protrusion 403 is also provided on the square tube 401. A lifting rod 404 is fixedly connected in the square tube 401, and a handle 405 is fixedly connected to the lifting rod 404.

[0048] The lower end of the square tube 401 is rotatably connected to four evenly arranged soil-removing plates 406. The inner wall of the soil-removing plate 406 is hinged to one end of the second connecting rod 407. The other end of the second connecting rod 407 is hinged to the connecting block 408.

The mounting base 4 504 is fixedly connected to the bottom surface of the mounting plate 101. The other end of the rotating rod 503 is hinged to one end of a connecting rod 3 505. The other end of the connecting rod 3 505 is hinged to a square tube 401.

[0050] In this embodiment, a manually controlled limiting mechanism can be set to keep the rack 205 disengaged from the gear 204 at all times, so that the device can move forward freely without being locked.

[0051] In this embodiment, the conveying pipe 6 is connected between the circular ring 302 and the square pipe 401.

[0052] A soybean cultivation method using a soybean cultivation device includes the following steps:

[0053] S1. Preparation: Pour the soybean seeds to be planted into the hopper 308, then rotate the screw 317 to move the slider 314 to the desired position in the receiving groove 306, then loosen the bolt 212, adjust the stop block 208 to the appropriate position, and then tighten the bolt 212 to fix it.

[0054] S2. Positioning and unloading: Grasp handle 405 to lift the rear end of mounting plate 101, so that support leg 105 leaves the ground, and then push the device forward. When the device moves forward, wheel 104 rotates, which drives rotating shaft 103 fixed to it to rotate. Rotating shaft 103 drives rotating shaft 202 to rotate through belt drive assembly 203. Rotating shaft 202 drives rack 205 to slide on L-shaped plate 206 through gear 204. When rack 205 moves to stop 208, it is blocked, thus preventing the device from moving forward.

[0055] During this process, rack 2 313, which is fixed to rack 1 205, moves synchronously and drives gear 2 312, which meshes with it, to rotate at a certain angle. Rotating shaft 3 310, which is fixed to gear 2 312, drives rotating sleeve 304 to rotate at a certain angle through belt drive assembly 2 309. Rotating sleeve 304 drives rotating disk 305 fixed to it to rotate, so that soybean seeds in receiving groove 306 at the lower end opening of ring 302 enter square tube 401 through transport pipe.

[0056] S3. Hole digging, sowing and unlocking: Grasp handle 1 405 and place support leg 105 on the ground. Then press down handle 1 405 to insert the soil-pulling plate 406, which is gathered at the lower end of square tube 401, into the ground to a certain depth. Then keep handle 1 405 still and pinch handle 2 410 upward. Handle 2 410 drives connecting block 408 to move upward through connecting rod 409. Connecting block 408 drives soil-pulling plate 406 to open through connecting rod 2 407 to pry open the soil and let soybean seeds in square tube 401 fall into the hole. Then release handle 1 405 and handle 2 410 to make them automatically reset.

[0057] When the square tube 401 moves downward, the connecting rod 505 causes the rotating rod 503 to rotate. The rotation of the rotating rod 503 drives the push rod 502, which is in contact with it, to move upward. The push rod 502 drives the L-shaped plate 206, which is fixed to it, to move upward, thereby causing the rack 205 to disengage from the gear 204. After disengagement, the rack 205 automatically resets under the action of the return spring 207. When the square tube 401 resets, the L-shaped plate 206 and the rack 205 reset simultaneously, at which point the device can continue to move forward.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.

5. A soybean planting device according to claim 4, characterized in that: The delivery pipe (6) is connected between the circular ring (302) and the square pipe (401).

6. A method for planting soybeans using a soybean planting device, characterized in that, Using the soybean planting apparatus as described in claim 5 includes the following steps: S1. Preparation: Pour the soybean seeds to be planted into the hopper (308), then rotate the screw (317) to move the slider (314) to the desired position in the receiving groove (306), then loosen the bolt (212), adjust the stop block (208) to the appropriate position, and then tighten the bolt (212) to fix it. S2, Positioning and Unloading: Grab handle one (405) to lift the rear end of the mounting plate (101), so that the support leg (105) leaves the ground, and then push the device forward. When the device moves forward, the wheel (104) rotates, which drives the rotating shaft one (103) fixed to it to rotate. The rotating shaft one (103) drives the rotating shaft two (202) to rotate through the belt drive assembly one (203). The rotating shaft two (202) causes the rack one (205) to slide on the L-shaped plate (206) through the gear one (204). When the rack one (205) moves to the stop (208), it is blocked, so that the device cannot continue to move forward. During this process, rack two (313) fixed to rack one (205) moves synchronously and drives gear two (312) meshing with it to rotate at a certain angle. Rotating shaft three (310) fixed to gear two (312) drives rotating sleeve (304) to rotate at a certain angle through belt drive assembly two (309). Rotating sleeve (304) drives rotating disk (305) fixed to it to rotate, so that soybean seeds in the receiving groove (306) at the lower opening of the ring (302) enter the square tube (401) through the transport pipe. S3, Hole Making, Sowing and Unlocking: Grab handle one (405) and place the support leg (105) on the ground. Then press down handle one (405) to make the soil-pulling plate (406) at the lower end of the square tube (401) insert into the ground to a certain depth. Then keep handle one (405) still and pinch handle two (410) upward. Handle two (410) drives the connecting block (408) to move upward through the connecting rod (409). The connecting block (408) drives the soil-pulling plate (406) to open through the connecting rod two (407) to pry open the soil and make the soybean seeds in the square tube (401) fall into the hole. Then release handle one (405) and handle two (410) to make them automatically reset. When the square tube (401) moves down, the rotating rod (503) is rotated through the connecting rod three (505). The rotation of the rotating rod (503) drives the push rod (502) that is in contact with it to move up. The push rod (502) drives the L-shaped plate (206) that is fixed to it to move up, thereby causing the rack one (205) to disengage from the gear one (204). After disengagement, the rack one (205) automatically resets under the action of the reset spring one (207). When the square tube (401) resets, the L-shaped plate (206) and the rack one (205) reset at the same time. At this time, the device can continue to move forward.
