Description

Technical Field

[0001] This invention belongs to the field of seeding equipment technology, specifically a mobile seeding device for crop seeds. Background Technology

[0002] In agricultural planting, sowing is a crucial step that determines crop emergence rate and final yield. Existing mobile sowing equipment typically includes a frame, a tillage mechanism, and a sowing mechanism. The frame is driven by traction machinery, the tillage mechanism is responsible for creating seed furrows in the soil, and the sowing mechanism is responsible for quantitatively dispensing seeds. However, existing sowing equipment generally suffers from a prominent problem in actual use: the feeding rate of the sowing mechanism is difficult to adjust flexibly according to actual operational needs. On the one hand, different crop seeds have significant differences in particle size and thousand-seed weight, and the same sowing mechanism often cannot adapt to the precision sowing requirements of multiple seeds. On the other hand, during operation, when the equipment's travel speed changes or soil conditions differ, the feeding rate of the seed metering device cannot be dynamically adjusted accordingly, resulting in uneven seeding rate per unit area and poor plant spacing, directly affecting crop emergence uniformity and subsequent growth. Summary of the Invention

[0003] The purpose of this invention is to provide a mobile seeding device for crops to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a mobile seeding device for crops, comprising a frame, a seeding mechanism mounted on the frame, and a tillage mechanism mounted on the front side of the frame; The seeding mechanism includes a fixed feeding ring and a storage hopper, and an opening and closing top feeding assembly is provided between the fixed feeding ring and the storage hopper; The reclamation mechanism includes a motor, a drilling assembly, and a loosening assembly. The loosening assembly is rotatably mounted on the upper side of the drilling assembly, and the motor drives the drilling assembly to rotate.

[0005] Preferably, a tow frame is hinged to the front of the top of the frame, two driving wheels are symmetrically installed on both sides of the rear of the frame, a hinge rod is hinged to the rear of the top of the frame, and a folding plate is installed at the end of the hinge rod away from the frame, the folding plate being V-shaped.

[0006] Preferably, the motor is fixedly installed on the front side of the top of the frame, the drilling assembly includes a rotating rod, the rotating rod is installed through the front side of the top of the frame, a drill bit is installed at the bottom end of the rotating rod, and bevel gears that mesh with each other are respectively installed on the output end of the motor and the outer surface of the rotating rod.

[0007] Preferably, the top of the rotating rod is open, and the rotating rod is connected to the inner cavity of the drill bit. The soil loosening component includes a rotating sleeve that rotates at the upper end of the rotating rod. A water supply pipe that is fixedly connected to a water supply pump is installed on the rotating sleeve. Several spray holes are evenly spaced through the inner cavity of the drill bit. The water supply pump sends water into the inner cavity of the drill bit through the water supply pipe and the inner cavity of the rotating rod, and sprays it out from the spray holes to the contact point between the drill bit and the soil, moistening the hard soil to be cultivated and assisting the drill bit in breaking through and cultivating the soil.

[0008] Preferably, the fixed feeding ring sleeve has a feed inlet on its top side that is aligned with the discharge port of the storage hopper, and a discharge port on its lower side. A rotating feeding ring sleeve is rotatably arranged inside the fixed feeding ring sleeve. A side motor frame is fixedly installed on the corresponding side of the fixed feeding ring sleeve, and a second motor for driving the rotating feeding ring sleeve to rotate is installed on the side motor frame.

[0009] Preferably, the rotating feeding ring includes a bushing, and two turntables are respectively provided on the outer surface of the bushing. One turntable is fixed on the outer surface of the bushing, and the other turntable rotates on the outer surface of the bushing. Both turntables have material gathering grooves on their outer surfaces.

[0010] Preferably, the bushing and the turntable rotating on its outer surface are respectively provided with a plurality of threaded holes, and the bushing and the turntable rotating on its outer surface are connected by fixing bolts.

[0011] Preferably, the outer surface of the storage hopper is welded with a plurality of support rods that are fixedly connected to the upper surface of the fixed feeding ring, and the opening and closing top material assembly includes a ring frame coaxially fixedly installed inside the feeding port of the storage hopper, a sliding rod is slidably installed inside the ring frame, and a top block is installed at the bottom end of the sliding rod.

[0012] Preferably, the top block is a cone shape that is narrower at the top and wider at the bottom, and the outer diameter of the lower side of the top block is adapted to the inner diameter of the discharge port of the storage hopper.

[0013] Preferably, the two sides of the material trough are sloped at less than 70°, and the end of the slide rod extending into the material trough through the feed inlet is provided with a ball groove, in which a ball bearing is rolled.

[0014] The beneficial effects of this invention are as follows: 1. This invention achieves precise adjustment of the seed metering device's feed rate by setting up a fixed feed ring, a rotating feed ring, and a motor-driven rotating feed ring. The material collection groove on the rotating feed ring rotates with the turntable, forming feed channels of different sizes with the inlet and outlet of the fixed feed ring, thereby precisely controlling the number of seeds fed each time. Users can flexibly adjust the single feed rate by controlling the rotation angle of the motor according to the particle size and thousand-grain weight of different crop seeds. This allows the same device to adapt to various seeds with large differences in particle size, such as corn, soybeans, wheat, and vegetables, improving the device's versatility and sowing accuracy.

[0015] 2. This invention achieves two-stage adjustment of the material collection trough volume by setting a bushing and a rotating disc on its outer surface connected by fixing bolts, with several threaded holes on each. Users can adjust the relative misalignment of the material collection troughs on the two discs by removing the fixing bolts, rotating the discs relative to each other to align the threaded holes in different positions, and then fixing them. This allows for further fine-tuning of the effective volume of the material collection trough based on the motor-driven adjustment. The two-stage adjustment mechanisms work together to make the adjustment range of the feeding amount wider and the precision higher, which can meet the requirements of more refined agronomic sowing.

[0016] 3. This invention utilizes an opening and closing top-feeding assembly, including a ring frame, a sliding rod, and a top block that is tapered at the top and narrow at the bottom. The outer diameter of the lower side of the top block matches the inner diameter of the discharge port of the storage hopper, thus controlling the opening and closing of the discharge port. When the sliding rod drives the top block upward, the top block leaves the discharge port, allowing the seeds to fall smoothly into the fixed discharge ring. When sowing needs to be stopped or the seed variety needs to be changed, the sliding rod drives the top block downward, and the outer wall of the top block fits tightly against the inner wall of the discharge port, achieving reliable sealing and preventing seed residue and mixing. Simultaneously, the ball bearings reduce the frictional resistance of the sliding rod as it moves within the material collection trough, ensuring the smoothness and reliability of the top-feeding action.

[0017] 4. This invention integrates the functions of assisted soil breaking and soil wetting by rotating a sleeve at the upper end of the rotating rod, installing a water supply pipe fixedly connected to the water supply pump on the sleeve, and opening several spray holes at equal intervals through the inner cavity of the drill bit. During the process of the drill bit rotating to break up hard soil, the water supply pump sends water through the water supply pipe into the inner cavity of the rotating rod and the drill bit, and finally sprays it precisely from the spray holes to the contact surface between the drill bit and the soil. The water quickly seeps into the soil, making the hard soil layer wet and soft, reducing the resistance of the drill bit breaking the soil. This allows the equipment to efficiently break up seed trenches that meet the requirements even on dry and compacted hard soil. At the same time, it avoids excessive wear of the drill bit caused by long-term high-load operation, extending the service life of the equipment. The soil in the seed trench that has been sprayed and moistened also provides a suitable humidity environment for seed implantation, which is conducive to improving the seed germination rate.

[0018] 5. This invention achieves automatic soil covering after reclamation by setting a hinge rod hinged to the rear side of the frame and a V-shaped clogging plate. When the equipment moves forward, the V-shaped clogging plate turns over the soil piled on both sides of the seed furrow and gathers it back into the seed furrow, completing the soil covering of the seeds after sowing. No additional manual or mechanical soil covering work is required, which simplifies the sowing process and reduces labor intensity. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, as Figures 1 to 8 As shown, this embodiment of the invention provides a mobile seeding device for crops, including a frame 1, a seeding mechanism 3 on the frame 1, and a tillage mechanism 2 on the front side of the frame 1. The seeding mechanism 3 includes a fixed feeding ring 31 and a storage hopper 32. An opening and closing top feeding component 322 is provided between the fixed feeding ring 31 and the storage hopper 32. The tillage mechanism 2 includes a motor 21, a drilling component 22 and a loosening component 23. The loosening component 23 is rotatably mounted on the upper side of the drilling component 22, and the motor 21 drives the drilling component 22 to rotate.

[0023] The frame 1 is the supporting foundation of the entire equipment. Its front end is connected to tractor or other traction machinery through the traction frame 11. The traction machinery drives the entire equipment to move in the field. The reclamation mechanism 2 is set on the front side of the frame 1 and is responsible for opening seed furrows in the soil. The sowing mechanism 3 is set on the frame 1 and is responsible for quantitatively distributing seeds into the seed furrows opened by the reclamation mechanism 2. The reclamation and sowing processes are completed in coordination during the equipment's movement, realizing integrated reclamation-sowing operations.

[0024] Example 2, as Figure 1 and Figure 2 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on the first embodiment, a traction frame 11 is hinged to the front of the top of the frame 1, two soil-collecting frames 12 are symmetrically installed on both sides of the rear of the frame 1, a hinge rod 121 is hinged to the rear of the top of the frame 1, and a collecting plate 122 is installed at the end of the hinge rod 121 away from the frame 1. The collecting plate 122 is in the shape of an "eight". The traction frame 11 is used to connect with the towing hook of tractors and other traction machinery. The hinged installation method allows the traction frame 11 to swing up and down within a certain range to adapt to the hooking height of different traction machinery. The soil-gathering frame 12 is set on both sides of the rear of the frame 1. The soil-gathering plate 122 is arranged in a figure-eight shape, with the larger opening facing forward, i.e., the direction of equipment movement, and the smaller opening facing backward. When the equipment moves in the field, after the drill bit 222 turns over the soil, the soil is pushed to both sides of the planting furrow to form a soil mound. Then the figure-eight shaped soil-gathering plate 122 gathers the soil on both sides and guides it back into the planting furrow, completing the soil covering of the seeds after sowing. The hinged design of the hinge rod 121 allows the soil-gathering plate 122 to float up and down with the terrain, maintaining good contact with the ground and ensuring the consistency of the soil covering effect.

[0025] Example 3, as Figure 2 and Figure 3 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on the first embodiment, a motor 21 is fixedly installed on the front side of the top of the frame 1. The drilling assembly 22 includes a rotating rod 221, which is installed through the front side of the top of the frame 1. A drill bit 222 is installed at the bottom of the rotating rod 221. The output end of the motor 21 and the outer surface of the rotating rod 221 are respectively equipped with meshing bevel gears 24. Motor 21 provides power for the reclamation operation of this equipment. Motor 21 is fixedly installed on the front top of the frame 1. A bevel gear 24 is installed on its output shaft. Another bevel gear 24 is installed on the outer surface of the rotating rod 221 and meshes with it. After the motor 21 starts, the power is transmitted to the rotating rod 221 through the two meshing bevel gears 24, driving the rotating rod 221 to rotate, which in turn drives the drill bit 222 at the bottom of the rotating rod 221 to rotate. During the rotation, the drill bit 222 cuts into the soil downwards, turning over the soil and forming a planting furrow. The bevel gear 24 transmission method has the advantages of compact structure, smooth transmission and strong load-bearing capacity, and is suitable for long-term reliable operation under the harsh working conditions of agricultural machinery.

[0026] Example 4, as Figure 3 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on embodiment three, the top of the rotating rod 221 is open, and the rotating rod 221 is connected to the inner cavity of the drill bit 222. The soil loosening component 23 includes a rotating sleeve 231 that rotates at the upper end of the rotating rod 221. A water supply pipe 232 fixedly connected to a water supply pump is installed on the rotating sleeve 231. A plurality of spray holes 233 are evenly spaced through the inner cavity of the drill bit 222. The water supply pump sends water through the water supply pipe 232 and the inner cavity of the rotating rod 221 into the inner cavity of the drill bit 222, and sprays it out through the spray holes 233 to the contact point between the drill bit 222 and the soil, moistening the hard soil to be cultivated and assisting the drill bit 222 in breaking and cultivating the soil. The rotating rod 221 is a hollow structure with an open top that connects to the inner cavity of the drill bit 222, forming a liquid flow channel from the top of the rotating rod 221 to the inner cavity of the drill bit 222. A rotating sleeve 231 is rotatably mounted at the upper end of the rotating rod 221. A water supply pipe 232 is fixedly connected to the rotating sleeve 231 and is connected to an external water pump. When the equipment is used for reclamation on dry, hard, compacted soil, the drill bit 222 encounters significant resistance during its rotation and cutting into the soil. This not only affects reclamation efficiency but also easily leads to excessive wear of the drill bit 222. At this time, the water pump is activated, and water is sent through the water supply pipe 232 into the rotating sleeve 231, and then flows into the inner cavity of the drill bit 222 through the inner cavity of the rotating rod 221. Finally, water is precisely sprayed from several spray holes 233 that are evenly spaced throughout the inner cavity of the drill bit 222. These spray holes 233 are evenly distributed along the circumference and axial direction of the drill bit 222, ensuring that water is evenly sprayed onto the contact surface between the drill bit 222 and the soil. The water quickly penetrates the soil, softening the originally dry and hard clods, reducing soil cohesion and frictional resistance. This allows the drill bit 222 to cut into the soil more easily during rotation, significantly improving reclamation efficiency. Simultaneously, it avoids excessive wear on the drill bit 222 caused by prolonged high-load operation, extending the equipment's service life. Furthermore, the moistened soil in the seed trench provides a suitable humidity environment for seed implantation, which is beneficial for improving seed germination rate. It is worth mentioning that the pump water source is supplied from the tractor connected to the traction frame 11. The rotating sleeve 231 and the rotating rod 221 are rotatably connected. The rotating sleeve 231 can be fixed to the frame 1 by a clamp to prevent the rotating rod 221 from rotating together with the rotating sleeve 231 when rotating.

[0027] Example 5: Figure 4 and Figure 7 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on the first embodiment, the top side of the fixed feeding ring 31 is provided with a feeding port 313 aligned with the discharge port of the storage hopper 32, the bottom side of the fixed feeding ring 31 is provided with a discharge port 314, a rotating feeding ring 323 is rotatably arranged inside the fixed feeding ring 31, a side motor frame 311 is fixedly installed on the corresponding side of the fixed feeding ring 31, and a second motor 312 for driving the rotating feeding ring 323 to rotate is installed on the side motor frame 311. The fixed feeding ring 31 is one of the core components of the sowing mechanism 3. It forms a cylindrical receiving cavity inside. The top side of the fixed feeding ring 31 has a feeding port 313, which is aligned with the discharge port at the bottom of the storage hopper 32, so that the seeds in the storage hopper 32 can fall into the fixed feeding ring 31 by gravity. The bottom side of the fixed feeding ring 31 has a discharge port 314, which is used to discharge a certain amount of seeds. The rotating feeding ring 323 is rotatably set in the internal receiving cavity of the fixed feeding ring 31. The second motor 312 is fixedly installed on one side of the fixed feeding ring 31 through the side motor frame 311. Its output shaft is connected to the rotating feeding ring 323, driving the rotating feeding ring 323 to rotate inside the fixed feeding ring 31. By controlling the rotation angle of the second motor 312, the circumferential position of the rotating feeding ring 323 relative to the fixed feeding ring 31 can be precisely adjusted, thereby adjusting the feeding amount.

[0028] Example 6, as Figure 8 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on embodiment five, the rotating feeding ring 323 includes a bushing 3231. Two turntables 3232 are respectively provided on the outer surface of the bushing 3231. One turntable 3232 is fixed on the outer surface of the bushing 3231, and the other turntable 3232 rotates on the outer surface of the bushing 3231. Both turntables 3232 have material gathering grooves 3233 on their outer surfaces. The bushing 3231 is the central rotating component of the rotating feeding ring 323, and it is connected to the output shaft of the second motor 312. Two turntables 3232 are set on the outer surface of the bushing 3231. One turntable 3232 is fixedly connected to the bushing 3231 and rotates synchronously with the bushing 3231. The other turntable 3232 is rotatably set on the outer surface of the bushing 3231 and can rotate independently relative to the bushing 3231. A material gathering groove 3233 is opened on the outer surface of the two turntables 3232. The material gathering groove 3233 is a groove structure that is recessed from the outer surface of the turntable 3232 to temporarily hold the seeds falling from the feed port 313. When the material gathering grooves 3233 on the two turntables 3232 are aligned, a large material holding space is formed. When the two turntables 3232 rotate relative to each other and the material gathering grooves 3233 are partially misaligned, the material holding space is reduced. This structure realizes the precise adjustment of the single feeding amount.

[0029] Example 7, as Figure 8 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on embodiment six, the bushing 3231 and a turntable 3232 rotating on its outer surface are respectively provided with a plurality of threaded holes 3234. The bushing 3231 and the turntable 3232 rotating on its outer surface are connected by fixing bolts 3235. The bushing 3231 has several threaded holes 3234 on its outer surface and on the inner wall of the turntable 3232, which is rotatably mounted on its outer surface. These threaded holes 3234 are evenly distributed circumferentially. When it is necessary to adjust the relative angle between the two turntables 3232, the operator first loosens and removes the fixing bolts 3235, then rotates the turntables 3232 relative to each other to the target angle, so that the threaded holes 3234 on the bushing 3231 and the threaded holes 3234 on the turntables 3232 are realigned, and then the fixing bolts 3235 are tightened to lock them in place. Through this structure, the user can make precise two-stage adjustments to the relative misalignment of the material collection troughs 3233 on the two turntables 3232, thereby further fine-tuning the effective volume of the material collection troughs 3233 on the basis of the adjustment driven by the motor 312. The two-stage adjustment mechanism works together to make the adjustment range of the material feeding amount wider and more accurate.

[0030] Example 8, as Figure 4 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on the first embodiment, the outer surface of the storage hopper 32 is welded with a plurality of support rods 321 that are fixedly connected to the upper surface of the fixed feeding ring 31. The opening and closing top feeding assembly 322 includes a ring frame 3221 coaxially fixedly installed inside the feeding port of the storage hopper 32, and a sliding rod 3222 is slidably installed inside the ring frame 3221. The storage hopper 32 is fixedly supported above the fixed feeding ring 31 by several support rods 321. One end of the support rod 321 is welded to the outer surface of the storage hopper 32, and the other end is fixedly connected to the upper surface of the fixed feeding ring 31 to ensure that the storage hopper 32 remains stable during operation. The opening and closing top material assembly 322 is used to control the opening and closing of the feeding port of the storage hopper 32. The ring frame 3221 is coaxially fixedly installed on the inner side wall of the feeding port of the storage hopper 32. The sliding rod 3222 slides through the ring frame 3221 and can slide up and down in the vertical direction. The ring frame 3221 provides a guiding function for the sliding rod 3222, ensuring that the sliding rod 3222 always remains vertical during the up and down movement and will not deviate.

[0031] Example 9, as Figure 5 and Figure 6 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on embodiment eight, a top block 3223 is installed at the top of the slide bar 3222. The top block 3223 is a cone shape that is narrow at the top and wide at the bottom. The outer diameter of the lower side of the top block 3223 is adapted to the inner diameter of the discharge port of the storage hopper 32. The top block 3223 is cone-shaped, narrower at the top and wider at the bottom. The diameter of the outer wall of the bottom side of the top block 3223 matches the inner diameter of the discharge port of the storage hopper 32. When the sliding rod 3222 moves the top block 3223 upward, the top block 3223 is pulled out from the discharge port of the storage hopper 32, the discharge port is opened, and the seeds can fall from the storage hopper 32 into the fixed discharge ring 31 below under the action of gravity. When it is necessary to stop sowing or change the seed variety, the sliding rod 3222 moves the top block 3223 downward, and the top block 3223 is reinserted into the discharge port of the storage hopper 32. Since the diameter of its lower outer wall matches the inner diameter of the discharge port, the outer wall of the top block 3223 fits tightly with the inner wall of the discharge port, achieving reliable sealing. The cone-shaped structure design allows the top block 3223 to automatically center when inserted into the discharge port. Even if there is a certain installation deviation, it can be smoothly inserted and sealed by the cone surface guide.

[0032] Example 10, as follows Figure 6 and Figure 8 As shown, this embodiment of the invention provides a mobile seeding device for crops. Based on embodiment nine, the two sides of the material gathering trough 3233 are sloped at less than 70°. The end of the slide rod 3222 extending into the material gathering trough 3233 through the feed inlet 313 is provided with a ball groove 3224. A ball ball 3225 is rolled in the ball groove 3224. The side walls of the material collection trough 3233 are sloped at less than 70°. This angle design facilitates the smooth sliding of seeds into and out of the material collection trough 3233 under gravity, preventing seeds from accumulating or getting stuck at the corners of the material collection trough 3233. The lower end of the slide rod 3222 extends into the material collection trough 3233 through the feed inlet 313 on the top side of the fixed feeding ring 31. The end of the slide rod 3222 that extends into the material collection trough 3233 has a ball groove 3224. A ball bearing 3225 is rolled in the ball groove 3224. The ball bearing 3225 changes the contact between the lower end of the slide rod 3222 and the rotating feeding ring 323 from sliding friction to rolling friction, which greatly reduces frictional resistance, ensures the smoothness of the slide rod 3222 during up and down movement, and also reduces the wear of parts and extends the service life of the equipment.

[0033] Working principle: Before operating the equipment, the user first adjusts the feeding amount of the sowing mechanism 3 according to the crop variety and seed size to be sown. The adjustment is divided into two levels. The first level is motor-driven adjustment. The user controls the rotation angle of the motor 312 to drive the rotating feeding ring 323 to rotate to the target position within the fixed feeding ring 31. The second level is manual fine adjustment. The user removes the fixing bolts 3235 and rotates the two turntables 3232 relative to each other to change the effective volume of the material collection trough 3233. After the adjustment is completed, the fixing bolts 3235 are screwed back in to lock. After adjusting the feed rate, the user connects the traction frame 11 to the tractor or other traction machinery, connects the water supply pipe 232 to the external water supply pump, loads the seeds to be sown into the storage hopper 32, and starts the traction machinery to drive the equipment in the field.

[0034] During the movement of the equipment, motor 21 starts and drives the rotating rod 221 to rotate through two meshing bevel gears 24. The rotating rod 221 drives the drill bit 222 to rotate. As the drill bit 222 rotates, it cuts into the soil, turning it over and forming a seed trench. When it encounters dry and compacted hard soil, the water pump starts. Water is sent into the rotating sleeve 231 through the water supply pipe 232, and then flows into the inner cavity of the drill bit 222 through the inner cavity of the rotating rod 221. Finally, it is precisely sprayed from the spray hole 233 in the inner cavity of the drill bit 222 to the contact surface between the drill bit 222 and the soil. The water quickly seeps into the soil, making the hard soil layer wet and soft, reducing soil resistance. The drill bit 222 can efficiently cut into and turn over the hard soil, completing the seed trench reclamation. The soil in the seed trench that has been sprayed and moistened also provides a suitable humidity environment for subsequent seed implantation. While the reclamation operation is underway, the opening and closing top material assembly 322 controls the opening of the discharge port of the storage hopper 32. When the turntable 3232 rotates, it drives the upper sliding rod 3222 to drive the top block 3223 to move upward. The top block 3223 is pulled out from the discharge port of the storage hopper 32. Under the action of gravity, the seeds fall from the storage hopper 32 through the inlet 313 into the material collection groove 3233 of the rotating material collection ring 323 inside the fixed material collection ring 31. As the rotating material collection ring 323 rotates, the seeds in the material collection groove 3233 are driven to the discharge port 314 on the lower side of the fixed material collection ring 31, and are discharged from the discharge port 314 and fall into the seed trench opened by the drill bit 222. As the equipment continues to move forward, the figure-eight shaped shovel 122 on the soil shovel frame 12 at the rear of the frame 1 turns over the soil piled on both sides of the seed furrow by the drill bit 222, gathers it back into the seed furrow, and completes the soil covering of the seeds. When it is necessary to stop sowing or change the seed variety, the slide bar 3222 drives the top block 3223 to move downward. The top block 3223 is reinserted into the discharge port of the storage hopper 32. The outer wall of the top block 3223 fits tightly with the inner wall of the discharge port to achieve reliable sealing and prevent the seeds from falling further.
