Description

Technical Field

[0001] This invention relates to the field of vegetable cultivation technology, specifically to a sowing and covering device for vegetable cultivation. Background Technology

[0002] In the process of vegetable cultivation, sowing is a key step that determines the subsequent growth trend. Its efficiency and quality directly affect the planting income. Traditional vegetable sowing relies heavily on manual operation. Growers need to manually dig holes, sow seeds, and then cover them with soil separately. In some cases, watering is also required. The whole process is cumbersome, time-consuming, and labor-intensive. Especially when planting on a large scale, the manual labor intensity is extremely high, the work efficiency is low, and it is difficult to meet the needs of modern agricultural production.

[0003] Patent application CN201810027082.7 discloses a sowing and covering device for vegetable cultivation, including a seed box, a water tank, a rotating disc, a covering disc, and a covering plate. This invention, by setting up a seed box and a water tank, allows for timely watering after sowing. After sowing, the rotation of the rotating disc causes the third moving groove to move the connecting column outward, thereby opening the covering plate outward. A rotating cylinder and a screw move the covering disc and rotating disc downward until they are close to the ground. Then, the rotating disc rotates in the opposite direction, and the covering plate returns to its original position under the action of the third moving groove and a spring. Simultaneously, the surrounding soil is moved inward by a scraper to cover the seeds, completing the covering process. This equipment integrates the functions of sowing, watering, and covering, reducing manual operation by workers, improving work efficiency, and is simple in structure and easy to use.

[0004] In practical applications, existing equipment often employs overly simplistic soil covering methods, leading to issues such as incomplete soil breaking and large clods of soil remaining after covering during vegetable cultivation. This negatively impacts the germination and breaking of vegetable seeds, hindering seed survival rates and impeding healthy seedling growth. Consequently, it fails to meet the demands of modern agricultural production for planting efficiency and crop quality. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sowing and soil covering device for vegetable cultivation, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sowing and soil covering device for vegetable planting, comprising an outer frame, a drive wheel rotatably connected to the outer wall of the outer frame via a bearing, a connecting column fixedly connected to the inner side of the rear of the outer frame, and a soil covering mechanism movably connected inside the outer frame.

[0007] The soil covering mechanism includes:

[0008] The outer shell has its outer wall movably connected to the outer frame. Four push rods are fixedly connected to the inner wall of the outer shell, each fixedly connected to one of the four corners of the inner wall. A sowing device is fixedly connected to the inner wall of the outer shell, and a motor is fixedly connected to the outer wall of the outer shell, providing power for the internal components. A baffle is fixedly connected to the inner wall of the front side of the outer shell, and internal components are movably connected to the inner wall of the outer shell. By setting a soil-covering mechanism, after the soil breaking and sowing processes are completed, the forward momentum of the equipment drives the bottom of the outer shell to perform soil-covering operations, covering the seeds with soil. A pre-set ground clearance at the bottom of the outer shell forms a constant soil-covering thickness control surface, ensuring that the soil layer always maintains a standard thickness, eliminating air permeability obstacles caused by excessive soil coverage, ensuring uniform spatial distribution of the planting units, laying a good foundation for subsequent vegetable growth, and improving the overall efficiency of vegetable cultivation.

[0009] According to the above technical solution, a partition is fixedly connected to the inner wall of the outer shell. The partition has a U-shaped structure. A sliding column is fixedly connected to the bottom of the partition. There are four sliding columns, which are respectively arranged on both sides of the bottom of the partition. A soil-breaking component is movably connected to the outer wall of the sliding column.

[0010] According to the above technical solution, a sliding groove is provided inside the bottom notch of the outer shell. There are two sliding grooves, which are respectively opened on both sides of the bottom notch of the outer shell. An intermediate plate is fixedly connected to the inner wall of each of the two sliding grooves. Two protruding parts are provided at the top of the two sliding grooves. These protruding parts are in contact with the surface of the soil breaking mechanism to prevent the equipment from suddenly entering the interior of the equipment when it is working. A guide plate is fixedly connected to the front side of the bottom of the outer shell. There are two guide plates, which are respectively set on both sides of the front end of the bottom notch of the outer shell. A compaction component is movably connected to the inner wall of each of the two intermediate plates.

[0011] According to the above technical solution, the internal component includes an eccentric column II, with rotating columns II fixedly connected to both sides of the eccentric column II. An eccentric column I is fixedly connected to the side of each of the two rotating columns II away from the eccentric column II. A rotating column I is fixedly connected to the end of each of the two eccentric columns I away from the rotating column II. The ends of each of the two rotating columns I away from the eccentric column I are rotatably connected to the inner wall of the outer casing via bearings. The output end of the motor is fixedly connected to the rotating column I. By setting the internal component, the radial extrusion of the right-angle plate II and the reciprocating motion of the force plate are synchronously driven during the soil crushing stage, forming a composite crushing trajectory. This motion mode, on the one hand, prevents soil aggregates from clogging in the conveying channel, and on the other hand, applies pressure to the soil from multiple directions, providing high-quality finely crushed soil for subsequent covering operations, thereby ensuring the germination environment of seeds and improving the overall quality and efficiency of vegetable cultivation.

[0012] According to the above technical solution, a connecting plate two is provided inside the outer shell. Sliding strips are fixedly connected to both sides of the connecting plate two. The side of the two sliding strips away from the connecting plate two is movably connected to the inner wall of the outer shell. A sliding groove plate is fixedly connected to the bottom of the connecting plate two. The inner wall of the sliding groove plate is movably connected to the eccentric column two. Right angle plates one is provided on both sides of the sliding groove plate. The tops of the two right angle plates one are fixedly connected to the bottom of the connecting plate two.

[0013] According to the above technical solution, the compaction assembly includes a hydraulic rod one, the bottom of which is fixedly connected to a partition plate. A hydraulic rod two is fixedly connected to the inner wall of the intermediate plate, and a liquid flow pipe is fixedly connected to the outer wall of the hydraulic rod two. The end of the liquid flow pipe away from the hydraulic rod two is fixedly connected to the hydraulic rod one, and the outer wall of the liquid flow pipe is fixedly connected to the outer shell. By setting the compaction assembly, the soil after breaking the soil is transported along the double-sided guide path during the forward movement of the equipment. During the transport, the right-angle plate two and the force plate continuously squeeze the soil to achieve secondary refinement of soil particles, eliminate residual clumps after vibration treatment by the breaking soil assembly, and ensure that a granular covering layer is formed on the seed surface, providing a stable environment for seed germination and seedling root development, thereby optimizing the yield efficiency of vegetable planting.

[0014] According to the above technical solution, the inner wall of the sliding groove is movably connected to a right-angle plate two, the side of the right-angle plate two near the middle plate is fixedly connected to a hydraulic rod two, and both ends of the right-angle plate two near the middle plate are fixedly connected to sliding columns two, and the outer walls of the two sliding columns two are fixedly connected to the middle plate.

[0015] According to the above technical solution, the soil-breaking component includes a movable plate, the inner wall of which is movably connected to a sliding column. An arc-shaped plate is fixedly connected to the bottom end of the movable plate away from the guide plate, and an inclined plate is fixedly connected to the bottom end of the movable plate away from the arc-shaped plate. A force-bearing plate is fixedly connected to the bottom of the movable plate, and the end of the force-bearing plate away from the inclined plate is fixedly connected to the arc-shaped plate. The end of the force-bearing plate away from the arc-shaped plate is also fixedly connected to the inclined plate. By setting up the soil-breaking component, high-frequency up-and-down reciprocating soil-breaking operation of the double-entry soil plate is realized. This design reduces the forward resistance of trenching and promotes in-situ soil fragmentation through vibration effect, effectively inhibiting the formation of large-diameter soil clods in the cover layer and avoiding physical pressure on seeds during germination. This optimizes the aeration and water permeability of the seedbed, provides a homogeneous germination environment for vegetable seeds, improves germination uniformity and seedling establishment rate, and thus enhances the overall efficiency of vegetable planting operations.

[0016] According to the above technical solution, a soil-insertion plate is fixedly connected to the end of the inclined plate away from the force-bearing plate, and a protruding strip is fixedly connected to the side of the soil-insertion plate near the movable plate. The protruding strip extends from the surface of the soil-insertion plate to the surface of the force-bearing plate. The bottom of the protruding strip is inclined, and the top of the protruding strip is horizontal.

[0017] According to the above technical solution, a long strip plate is fixedly connected to the top of the movable plate, and a strip groove is opened on the outer wall of the top of the long strip plate. The outer wall of the eccentric column is movably connected to the strip groove on the top of the long strip plate.

[0018] Compared with the prior art, the present invention provides a sowing and soil covering device for vegetable planting, which relates to mechanized agricultural machinery manufacturing technology and has the following beneficial effects:

[0019] 1. This invention enables high-frequency reciprocating soil breaking operations by setting up a soil breaking component, which reduces the forward resistance of trenching and promotes in-situ soil fragmentation through vibration effect. This effectively inhibits the formation of large-diameter soil clods in the cover layer and avoids physical pressure on seeds during germination. This optimizes the aeration and water permeability of the seedbed, provides a homogeneous germination environment for vegetable seeds, improves germination uniformity and seedling establishment rate, and thus enhances the overall efficiency of vegetable planting operations.

[0020] 2. By setting up a compaction component, the soil after breaking the soil is transported along the double-sided guide path during the forward movement of the equipment. During the transport, the right-angle plate and the force plate continuously squeeze the soil to achieve secondary refinement of soil particles, eliminate residual clumps after vibration treatment of the breaking component, and ensure that a particle covering layer is formed on the seed surface, providing a stable environment for seed germination and seedling root development, thereby optimizing the yield efficiency of vegetable planting.

[0021] 3. This invention, by setting up a soil covering mechanism, after the soil breaking and sowing processes are completed, uses the forward power of the equipment to drive the bottom of the outer shell to carry out soil covering operations, covering the seeds with soil. The preset gap between the bottom of the outer shell and the ground forms a constant soil covering thickness control surface, ensuring that the soil covering layer always maintains a standard thickness, eliminating the air permeability obstruction caused by excessive soil covering, ensuring uniform spatial distribution of planting units, laying a good foundation for subsequent vegetable growth, and improving the overall efficiency of vegetable planting.

[0022] 4. By setting internal components, the present invention synchronously drives the radial extrusion of the right-angle plate II and the reciprocating motion of the force plate during the soil crushing stage, forming a composite crushing trajectory. This motion mode prevents soil aggregates from clogging in the conveying channel on the one hand, and applies pressure to the soil from multiple directions on the other hand, providing high-quality fine soil for subsequent covering operations, thereby ensuring the germination environment of seeds and improving the overall quality and efficiency of vegetable planting.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0038] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0039] Example 1: See Figures 1-5The present invention provides a technical solution: a sowing and soil covering device for vegetable planting, including an outer frame 1, the outer wall of the outer frame 1 is rotatably connected to a drive wheel 101 via a bearing, and a soil covering mechanism 2 and a flattening component 3 are provided to ensure the integrity and flatness of the soil covering after furrow sowing. The soil covering mechanism 2 performs the initial soil covering operation, while the flattening component 3 performs the final flattening and moderate compaction of the soil covering layer through an elastic adaptive structure to form a surface soil structure that is conducive to seed germination. A connecting column 102 is fixedly connected to the inner side of the rear of the outer frame 1, and the soil covering mechanism 2 is movably connected to the inside of the outer frame 1. The outer wall of the connecting plate 103 is rotatably connected to the flattening component 3 via a bearing.

[0040] The soil covering mechanism 2 includes a housing 201, the outer wall of which is movably connected to the outer frame 1. Four push rods 203 are fixedly connected to the inner wall of the housing 201, each fixedly connected to one of the four corners of the housing 201. A seeding device 202 is fixedly connected to the inner wall of the housing 201. A motor 204 is fixedly connected to the outer wall of the housing 201. A baffle 205 is fixedly connected to the inner wall of the front side of the housing 201. An internal component 21 is movably connected to the inner wall of the housing 201. A partition 206, which has a U-shaped structure, is fixedly connected to the bottom of the partition 206. A sliding column 2 is fixedly connected to the bottom of the partition 206. 07. There are four sliding columns 207, which are respectively set on both sides of the bottom of the partition 206. The outer wall of the sliding column 207 is movably connected to the soil breaking component 23. The bottom notch of the outer shell 201 has two sliding grooves 208, which are respectively set on both sides of the bottom notch of the outer shell 201. The inner wall of each sliding groove 208 is fixedly connected to a middle plate 209. The front side of the bottom of the outer shell 201 is fixedly connected to two guide plates 2010, which are respectively set on both sides of the front end of the bottom notch of the outer shell 201. Each intermediate plate 209 has a compaction component 22 movably connected to its inner wall. When the equipment is running, the motor 204 provides power to drive the operation of the internal components 21, thereby coordinating the various parts to complete the breaking, sowing, soil refining, and covering operations. The outer shell 201 serves as the overall load-bearing frame, and its movable connection with the outer frame 1 allows for positional adjustments to suit different operating scenarios. The push rods 203 at the four corners help maintain the stability of the internal structure of the outer shell. During the breaking stage, the breaking component 23 reciprocates along the sliding column 207 under the drive of the internal components 21, realizing the breaking operation on the ground surface. The U-shaped partition 206 provides fixed support for the sliding column 207 and also provides support for the sowing device 20. The seeding process 2 provides space; after breaking the soil, the soil flows through the bottom opening of the outer shell 201, and the guide plates 2010 on both sides guide the soil to converge in the middle, preparing for subsequent covering; at the same time, the compaction component 22 supported by the middle plate 209 compacts and refines the soil passing through the sliding groove 208, eliminating large clods; the seeding device 202 sows simultaneously with the breaking operation, while the baffle 205 prevents soil from entering the equipment from the front end; finally, the refined soil covers the seeds under the propulsion of the outer shell 201, completing the covering operation. The entire process achieves integrated operation from breaking the soil, sowing, to soil refinement and covering through the orderly linkage of various components.

[0041] The flattening assembly 3 includes a flattening roller 303. Both ends of the flattening roller 303 are rotatably connected to rotating plates 302 via bearings. Rotating plates 301 are fixedly connected to the ends of the two rotating plates 302 away from the flattening roller 303. The two rotating plates 302 are rotatably connected to a connecting plate 103 via bearings. A connecting column 304 is fixedly connected to the end of the two rotating plates 301 away from the rotating plates 302. An elastic component 305 is rotatably connected to the outer wall of the connecting column 304 via bearings. The end of the elastic component 305 away from the connecting column 304 is rotatably connected to the connecting column 102 via a bearing. During equipment movement, the flattening roller 303 contacts the ground surface and rotates as the equipment moves forward, thus flattening the surface after the covering mechanism 2 has completed the initial covering. The soil layer is compacted and leveled. The rotating plate 2 302 can flexibly adjust its angle according to the undulation of the flattening roller 303, so that the overall height of the flattening roller 303 can be adaptively adjusted according to the flatness of the ground. The connecting column 2 304 connects the two rotating plates 1 301 and serves as the connection fulcrum of the elastic component 305. One end of the elastic component 305 is connected to the connecting column 2 304 through a bearing, and the other end is rotatably connected to the connecting column 102 on the outer frame 1. Utilizing the elastic force generated by its own elastic deformation, it always applies pressure to the rotating plates 1 301 and 2 302 to ensure that the flattening roller 303 is in contact with the ground. Even when there are undulations in the ground, it can maintain a stable rolling pressure through the expansion and contraction compensation of the elastic component and the angle adjustment of the rotating plate, ultimately achieving the leveling treatment of the topsoil layer.

[0042] Example 2: Please refer to Figures 6-11Based on Embodiment 1, the present invention provides a technical solution: To improve the soil breaking quality and soil covering effect of the equipment, an internal component 21, a compaction component 22, and a soil breaking component 23 are provided. The soil breaking component 23 is responsible for efficiently breaking the soil and initially crushing the soil. The compaction component 22 further refines the soil after breaking the soil. The internal component 21 provides power transmission and motion coordination for the former two components. The internal component 21 includes an eccentric column 214, with rotating columns 213 fixedly connected to both sides of the eccentric column 214. An eccentric column 1 is fixedly connected to the side of each rotating column 213 away from the eccentric column 214. 212, two eccentric columns 212 are fixedly connected to a rotating column 211 at the end away from the rotating column 213. The ends of both rotating columns 211 away from the eccentric column 212 are rotatably connected to the inner wall of the housing 201 via bearings. The output end of the motor 204 is fixedly connected to the rotating column 211. A connecting plate 216 is provided inside the housing 201. Sliding strips 215 are fixedly connected to both sides of the connecting plate 216. The side of each sliding strip 215 away from the connecting plate 216 is movably connected to the inner wall of the housing 201. A sliding groove plate 217 is fixedly connected to the bottom of the connecting plate 216. The inner wall of the slide plate 217 is movably connected to the eccentric column 214. Right-angle plates 218 are provided on both sides of the slide plate 217, and the tops of both right-angle plates 218 are fixedly connected to the bottom of the connecting plate 216. When the equipment is working, the motor 204 acts as a power source, and its output drives the rotating column 211 to rotate around the bearing on the inner wall of the outer casing 201. The rotating column 211 then drives the eccentric column 212, the rotating column 213, and the eccentric column 214 to rotate synchronously. Because the eccentric columns 212 and 214 are eccentric structures, they will experience periodic positional shifts during rotation. The eccentric column 214 is movably connected to the inner wall of the chute plate 217. When the eccentric column 214 rotates, its positional offset is transmitted to the connecting plate 216 through the chute plate 217. The sliding strips 215 on both sides of the connecting plate 216 are movably connected to the inner wall of the outer shell 201, which restricts the movement direction of the connecting plate 216, causing it to reciprocate linearly along the sliding strips 215 on the inner wall of the outer shell. The right-angle plate 218 fixed at the bottom of the connecting plate 216 reciprocates synchronously with the connecting plate 216, thereby applying periodic force to the compaction component or soil breaking component that cooperates with it, so as to achieve soil crushing and compaction.

[0043] The compaction assembly 22 includes a hydraulic rod 221, the bottom of which is fixedly connected to a partition 206. A hydraulic rod 222 is fixedly connected to the inner wall of the intermediate plate 209. A fluid pipe 225 is fixedly connected to the outer wall of the hydraulic rod 222. The end of the fluid pipe 225 away from the hydraulic rod 222 is fixedly connected to the hydraulic rod 221. The outer wall of the fluid pipe 225 is fixedly connected to the outer shell 201. A right-angle plate 223 is movably connected to the inner wall of the sliding groove 208. The side of the right-angle plate 223 near the intermediate plate 209 is fixedly connected to the hydraulic rod 222. Sliding columns 224 are fixedly connected to both ends of the right-angle plate 223 near the intermediate plate 209. The wall is fixedly connected to the intermediate plate 209. This component realizes the function of soil compaction and refinement through hydraulic transmission and mechanical limiting. The hydraulic energy generated by the extension and retraction of the hydraulic rod 221 is transmitted to the hydraulic rod 222 through the flow pipe 225. The hydraulic rod 222 is driven by the hydraulic energy to extend and retract, thereby pushing the right-angle plate 223 to move. The sliding columns 224 on both sides of the right-angle plate 223 are used to limit the movement trajectory of the right-angle plate 223, so that it maintains a stable linear reciprocating motion. When the equipment moves and the soil after breaking the soil flows through the area, the right-angle plate 223 continuously applies a squeezing force to the soil under hydraulic drive. By repeatedly crushing the remaining soil clods, the soil is refined in a secondary manner.

[0044] The ground-breaking component 23 includes a movable plate 231. The inner wall of the movable plate 231 is movably connected to the sliding column 207. An arc-shaped plate 232 is fixedly connected to the bottom end of the movable plate 231 away from the guide plate 2010. An inclined plate 234 is fixedly connected to the bottom end of the movable plate 231 away from the arc-shaped plate 232. A force-bearing plate 233 is fixedly connected to the bottom of the movable plate 231. The end of the force-bearing plate 233 away from the inclined plate 234 is fixedly connected to the arc-shaped plate 232, and the end of the force-bearing plate 233 away from the arc-shaped plate 232 is fixedly connected to the inclined plate 234. A soil-insertion plate 235 is fixedly connected to the end of plate 234 away from the load-bearing plate 233. A protruding strip 236 is fixedly connected to the side of soil-insertion plate 235 near movable plate 231. The protruding strip 236 extends from the surface of soil-insertion plate 235 to the surface of load-bearing plate 233. The bottom of the protruding strip 236 is inclined and the top of the protruding strip 236 is horizontal. A long strip plate 237 is fixedly connected to the top of movable plate 231. A strip groove is opened on the outer wall of the top of the long strip plate 237. The outer wall of eccentric column 212 is movably connected to the strip groove on the top of long strip plate 237.

[0045] The movable plate 231 is movably connected to the sliding column 207 and can reciprocate along the sliding column 207. Driven by the internal component 21, the movable plate 231 drives the bottom components to move synchronously. The soil entry plate 235 at the end of the inclined plate 234 directly contacts the ground to complete the soil breaking operation. The raised strips 236 on the surface of the soil entry plate 235 extend from the soil entry plate to the force plate 233 and move synchronously with the soil entry plate 235 during the soil breaking process, further enhancing the cutting and breaking effect on the soil and initially breaking up large pieces of soil. The two ends of the force plate 233 are fixed to the arc plate 232 and the inclined plate 234 respectively, which strengthens the structural stability of the entire component. The arc plate 232 can guide the soil that has been turned over to flow to both sides or in a specified direction during soil breaking, avoiding soil accumulation that hinders subsequent operations and realizing the coordinated operation of soil breaking and initial soil crushing.
