Description

Technical Field

[0001] This invention relates to an agricultural machinery device, and more specifically to an adjustment mechanism for a vegetable planting robot. Background Technology

[0002] With the advancement of technology, more and more mechanized equipment is being applied to agriculture, thereby liberating labor and improving production efficiency. Large machinery and robots used for vegetable cultivation are already widely used in agricultural planting, but their application is mostly limited to large, planned fields. For small-scale vegetable cultivation, there is no need to purchase and use large machinery, which creates market demand for small planting robots. The basic functions of small planting robots include plowing, sowing, and soil removal. Specific components of each functional mechanism need to be replaced to handle different soil types, seed types, and soil cover conditions, which increases the complexity of robot use. If the functional mechanisms could be modularly disassembled and replaced as a whole, it would improve the user experience and reduce the difficulty of use. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an adjustment mechanism for a vegetable planting robot. Through the modular and detachable design of the frame and various functional mechanisms, users can easily replace modules as needed, reducing debugging difficulty and improving ease of use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a vegetable planting robot adjustment mechanism, comprising a frame and wheels disposed at the lower part of the frame for movement, wherein a plurality of operating modules for vegetable planting are arranged from front to back on the frame, the frame comprising a quick-release frame arranged sequentially from front to back, wherein a placement cavity is formed in the middle of the quick-release frame, and the operating module has a module outer frame adapted to the size of the placement cavity, wherein locking mechanisms are correspondingly provided on the quick-release frame and the module outer frame for locking and unlocking between the two; the specifications of different operating modules can be adjusted by quickly disassembling and replacing each operating module.

[0005] As an improvement, a support edge is provided on the upper periphery of the modular frame, which supports and limits the movement of the quick-assembly frame.

[0006] As an improvement, the locking mechanism includes a locking wheel mounted on the quick-release frame and a locking groove mounted on the module outer frame. The locking wheel is rotatably mounted on the quick-release frame, with its outer side extending outward from the quick-release frame to form an operating part, and its inner side extending outward from the quick-release frame to the placement cavity space to form a locking part. The locking wheel also has an unlocking notch on the side of the locking part. When the operating module is inserted into the placement cavity, the locking groove on the module outer frame corresponds to the positions of the locking part and the unlocking notch. When the locking part is rotated into the quick-release frame and the unlocking notch corresponds to the locking groove, the module outer frame is in an unlocked state. When the unlocking notch is rotated into the quick-release frame and the locking part rotates to the locking groove, the module outer frame is in a locked state.

[0007] As an improvement, the locking mechanism also includes a limit pin, which is located on the side of the operating part on the outside of the quick-release frame. When the unlocking notch rotates into the quick-release frame and is in place, a part of the unlocking notch extends out of the outside of the quick-release frame and corresponds to the limit pin. The operating limit pin abuts against the unlocking notch, thereby restricting the rotation of the locking wheel.

[0008] As an improvement, the locking wheels are positioned symmetrically on the left and right sides of the quick-release frame.

[0009] As an improvement, the locking part is provided with a clearance slope along the circumference of the locking wheel. When the locking part rotates into the locking groove until it is in place, the clearance slope does not contact the groove wall of the locking groove until the locking part of the rear section of the clearance slope enters the locking groove and the locking part abuts against the lower groove wall of the locking groove.

[0010] As an improvement, the operating module includes a plowing mechanism, a sowing mechanism, and a soil-removing mechanism, with a quick-assembly frame configured as three for sequential installation of the plowing mechanism, sowing mechanism, and soil-removing mechanism.

[0011] As an improvement, the wheel body includes a pair of front wheels and a rear wheel. The pair of front wheels are separated to form an operating space in the middle for the operation module. The rear wheel is pivotally located in the middle of the rear and is connected to a power unit for driving and steering. The plowing mechanism, the sowing mechanism, the soil-pulling mechanism, and the rear wheel are arranged sequentially on the axis of the operating space from front to back.

[0012] As an improvement, the plowing mechanism includes a pair of plowing ramps and a plowing disc. The pair of plowing ramps are raised and lowered and symmetrically arranged at the front of the operating space. When the pair of plowing ramps descend, they are arranged in a triangle, thus scooping up the soil and dropping it backward upon contact with it. The plowing disc is raised and lowered and located behind the plowing ramps. When the plowing disc descends, it contacts the soil and separates the soil scooped up by the plowing ramps to both sides. The sowing mechanism is located behind the plowing disc and is used to sow seeds into the soil. The soil-pulling mechanism includes a pair of soil-pulling plates. The pair of soil-pulling plates are raised and lowered and symmetrically arranged at the rear of the operating space. When the pair of soil-pulling plates descend, they are arranged in an inverted triangle, contacting the soil and pulling the sown soil towards the center. When the sowing robot is operating to sow seeds, the plowing mechanism, the sowing mechanism, the soil-pulling mechanism, and the rear wheels sequentially complete the loosening and separating of the soil, sowing, pulling and concentrating, and compacting of the soil.

[0013] The beneficial effects of this invention are:

[0014] 1. Through modular structural assembly and disassembly design, specific modules can be directly replaced according to different soil types, seed types, soil cover, etc. For example, specific plowing mechanism modules and soil-moving mechanism modules can be directly replaced with modules of appropriate specifications according to different soil hardness. For example, specific seeding mechanism modules can be directly replaced according to different types of vegetables to be planted, thereby realizing the change of seed types without the need for the cumbersome process of emptying the seed storage cavity and then adding seeds. Overall, it improves the convenience of using the equipment for users.

[0015] 2. The equipment has a simple structure and is easy to debug. It can be applied to the automation needs of small-scale vegetable planting, meet the needs of most people to easily get started, and meet the needs of people's leisure planting life after the improvement of living standards.

Detailed Implementation

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-8 The diagram shows a specific embodiment of the vegetable planting robot adjustment mechanism of the present invention. This embodiment includes a frame 1 and wheels 2 disposed at the lower part of the frame 1 for movement. Several operating modules for vegetable planting are arranged from front to back on the frame 1. The frame 1 includes a quick-release frame 11 arranged sequentially from front to back. A placement cavity 12 is formed in the middle of the quick-release frame 11. The operating module has a module outer frame 3 adapted to the size of the placement cavity 12. Locking mechanisms 4 are correspondingly provided on the quick-release frame 11 and the module outer frame 3 to lock and unlock between them. The specifications of different operating modules can be adjusted by quickly disassembling and replacing each operating module.

[0027] When using this invention, with the improvement of living standards, more and more people are returning to the outdoors as a way to relax outside of their daily work, and some people choose to return to the countryside to grow vegetables in outdoor settings. For this kind of small-scale vegetable planting needs, users want a more convenient way of operation, without having to do complicated debugging of specific mechanical parts. Instead, they can directly replace and use the modular parts configured in the equipment to deal with different situations.

[0028] For planting vegetables on leveled land, the conventional approach is to first plow and loosen the soil, then sow the seeds, and finally cover the seeds with soil. This completes the planting process. Therefore, the operating module can specifically include a plowing mechanism 5, a sowing mechanism 6, and a soil-removing mechanism 7. These three modules are arranged sequentially on the vegetable planting robot, completing the plowing, sowing, and soil-covering process as the robot moves in a straight line. As an innovation of this invention, each operating module can be directly disassembled and replaced as needed, making it convenient for ordinary gardening enthusiasts. By directly replacing operating modules, such as the plowing mechanism 5, the specific plowing structure can be adjusted according to the soil's hardness and levelness; the sowing mechanism 6 can be composed of multiple modules carrying different seeds, allowing for quick and easy replacement to meet planting needs without having to remove existing seeds from one mechanism and refill with new ones, thus improving efficiency and meeting requirements; and the soil-removing mechanism 7 can be adjusted according to the soil's hardness and coarseness. Overall, this improves the ease of use for non-professional gardening enthusiasts, catering to diverse needs.

[0029] In terms of technical implementation, quick-assembly frames 11 are sequentially arranged from front to back on the frame 1 to meet the assembly and disassembly requirements of specific operating modules. The placement cavity 12 formed in the middle of the quick-assembly frame 11 is adapted to the outer frame of the operating module, i.e., the module outer frame 3. After the size specifications of both are determined, each standardized manufactured operating module can be adapted for quick assembly and disassembly, thereby effectively controlling the cost of the installed modules and frame structure, and allowing for compatibility and universality between different models. The quick-assembly frame 11 and the module outer frame 3 are easy to assemble and disassemble, simply by placing them downwards or removing them upwards. The two are locked and unlocked by the locking mechanism 4, thereby providing the structural stability of the overall equipment, allowing each operating module to move stably with the vegetable planting robot to complete its respective function.

[0030] As an improved specific implementation, the upper periphery of the module frame 3 is provided with a support edge 31, which is supported and limited by the periphery of the quick-assembly frame 11.

[0031] like Figure 2 As shown, the structural alignment of the quick-assembly frame 11 and the module outer frame 3 is achieved by the set support edge 31. After the support edge 31 is placed around the periphery of the quick-assembly frame 11, it can stabilize the upper and lower positions of the module outer frame 3, making it easier for the locking mechanism 4 to complete the alignment and structural locking.

[0032] As an improved specific implementation, the locking mechanism 4 includes a locking wheel 41 disposed on the quick-release frame 11 and a locking groove 42 disposed on the module outer frame 3. The locking wheel 41 is rotatably disposed on the quick-release frame 11, and the outer side of the locking wheel 41 extends out of the quick-release frame 11 to form an operating part 411, and the inner side of the locking wheel 41 extends out of the quick-release frame 11 to the space of the placement cavity 12 to form a locking part 412. The locking wheel 41 is also provided with an unlocking notch 413 on the side of the locking part 412. When the operating module is inserted into the placement cavity 12, the locking groove 42 on the module outer frame 3 corresponds to the position of the locking part 412 and the unlocking notch 413. When the locking part 412 is rotated into the quick-release frame 11 and the unlocking notch 413 corresponds to the locking groove 42, the module outer frame 3 is in an unlocked state. When the unlocking notch 413 is rotated into the quick-release frame 11 and the locking part 412 is rotated to the locking groove 42, the module outer frame 3 is in a locked state.

[0033] like Figure 1 , 3 As shown in Figure 4, the locking wheel 41 is adjusted to the unlocked state before the operation module is installed, and the unlocking notch 413 corresponds to the placement cavity 12 (as shown in Figure 4). Figure 3 (As shown); then the user places the operating module into the placement cavity 12. The module outer frame 3 corresponds to the size of the quick-release frame 11. After being placed in place, the support along the support 31 supports the periphery of the quick-release frame 11 for limiting. The position of the locking groove 42 corresponds to the side of the locking wheel 41. The user can apply force to the exposed operating part 411 on the outside of the quick-release frame 11 and rotate it to gradually turn the unlocking notch 413 into the cavity of the quick-release frame 11 from one side, while the locking part 412 on the other side rotates out of the cavity of the quick-release frame 11 and into the locking groove 42, thereby achieving the locking state of the module outer frame 3 (as shown). Figure 4 (As shown). When it is necessary to disassemble the operating module, the user can rotate the locking wheel 41 in the opposite direction to the initial unlocked position to disassemble and replace the operating module.

[0034] As an optimized design, the locking wheels 41 are positioned symmetrically on the left and right sides of the quick-release frame 1l. This ensures a stable locking state in both left and right positions and guarantees smooth force distribution on the structure.

[0035] As an improved specific implementation, the locking mechanism 4 also includes a limiting pin 414. The limiting pin 414 is disposed on the side of the quick-release frame 11 corresponding to the side of the operating part 411. When the unlocking notch 413 rotates into the quick-release frame 11 and is in place, a part of the unlocking notch 413 extends out of the quick-release frame 11 and corresponds to the limiting pin 414. The operating limiting pin 414 abuts against the unlocking notch 413, thereby restricting the rotation of the locking wheel 41.

[0036] like Figure 3 , 4 As shown, to further improve the stability of the locked state, a limiting pin 414 is specifically designed according to the structure of the locking wheel 41. The limiting pin 414 is slidably set on the outside of the quick-release frame 11. The outer circumference of the locking wheel 41 itself is a circular surface, and after setting the unlocking notch 41 3, the unlocking notch 41 3 is a good limiting position. Therefore, the rotation limit position of the locking wheel 41 is set as follows: after rotating to the limit position of the locked state, a part of the unlocking notch 413 extends out of the outside of the quick-release frame 11 and corresponds to the limiting pin 414 (e.g., Figure 4 As shown, at this time, the operating limit pin 414 slides to abut against the unlocking notch 413, which can block the locking wheel 41 from rotating in the opposite direction, thereby achieving the function of locking the locking wheel 41. If unlocking is required, the limit pin 414 must be moved away and reset. This provides an extra layer of locking protection for the locking wheel 41 and improves the stability of the operation module after installation. In addition, this solution utilizes the structural design characteristics of the locking wheel 41 itself to complete the cooperation between structures, effectively controlling the overall manufacturing cost, while having a stable functional effect.

[0037] As an optimized design, a limiting wall 416 can be further provided in the cavity of the quick-release frame 11 to limit the reciprocating rotation limit position of the locking wheel 41. When the locking wheel 41 rotates to the unlocked state or the locked state is in place (e.g. Figure 3 , 4 As shown, the inner wall of the locking wheel 41 will abut against the limiting wall 416, thereby preventing the locking wheel 41 from continuing to rotate. Due to the design of the unlocking notch 41 3 on the inner wall of the locking wheel 41, the inner wall forms a good contact surface, thereby effectively limiting the stopping limit position of the locking wheel 41.

[0038] As an improved specific implementation, the locking part 412 is provided with a clearance slope 415 along the circumference of the locking wheel 41. When the locking part 412 rotates into the locking groove 42 until it is in place, the clearance slope 415 does not contact the groove wall of the locking groove 42 until the rear section of the locking part 412 enters the locking groove 42 and the locking part 412 abuts against the lower groove wall of the locking groove 42.

[0039] like Figure 5As shown, the yielding slope 415 is a face that is obliquely cut at the lower part of the locking part 412. When the locking part 412 just rotates into the locking groove 42, the lower part of the locking part 412 will not contact the lower groove wall of the locking groove 42 due to the presence of the yielding slope 415. After continued rotation, the yielding slope 415 and the locking part 412 will contact the lower groove wall of the locking groove 42 and press down on the lower groove wall of the locking groove 42, that is, press down on the module outer frame 3. This gradual contact and pressing, combined with the support edge 31 and the outer peripheral limit of the quick-release frame 11, can make the locking more gentle. Even if the module outer frame 3 is not in the correct position at the beginning, the locking part 412 will not be unable to enter the locking groove 42 due to interference. It can enter the locking groove 42 through the yielding slope 415 and gradually press down until the locking part 412 is limited, and finally keep the module outer frame 3 and the quick-release frame 11 in a stable locked state.

[0040] As an improved specific implementation, the operation module includes a plowing mechanism 5, a sowing mechanism 6, and a soil-removing mechanism 7, and the quick-assembly frame 11 is configured as three for the sequential installation of the plowing mechanism 5, the sowing mechanism 6, and the soil-removing mechanism 7.

[0041] like Figure 1 As shown, based on the previous introduction to the vegetable planting function, the most commonly used operating modules are the plowing mechanism 5, the sowing mechanism 6, and the soil-removing mechanism 7. To further specify the function of this invention, three quick-assembly frames 11 are specifically set up to allow the sequential installation of the plowing mechanism 5, the sowing mechanism 6, and the soil-removing mechanism 7, thereby realizing the functionality of the three operating modules. Of course, for functional expansion, more than three quick-assembly frames 11 can be set up as needed. For example, to provide power to the overall equipment, a battery module 23 can be installed using an additional quick-assembly frame 11. Then, by connecting the battery module 23 to the equipment's power system and circuit system for power supply, remote control of the vegetable planting robot can be achieved.

[0042] As an improved specific implementation, the wheel body 2 includes a pair of front wheels 21 and a rear wheel 22. The pair of front wheels 21 are separated to form an operating space in the middle for the operation module to use. The rear wheel 22 is swayably arranged in the middle of the rear and is connected to the power unit for driving and steering. The plowing mechanism 5, the sowing mechanism 6, the soil-pulling mechanism 7, and the rear wheel 22 are arranged sequentially from front to back on the axis of the operating space.

[0043] like Figure 1 , 7As shown in Figure 8, a pair of front wheels 21 provide structural support and stability at the front. The space between the front wheels 21 serves as the operating space. When the robot moves, the plowing mechanism 5, the sowing mechanism 6, the soil-moving mechanism 7, and the rear wheel 22, which are sequentially arranged on the axis of the operating space, can perform their respective functions. One rear wheel 22 provides rear support, and the power unit is connected to the rear wheel 22. The robot moves and turns by rotating and swinging the rear wheel 22. The single-wheel design allows the robot to have a more flexible rotation state, a smaller rotation radius, and is more adaptable to the needs of small-area sites. Furthermore, when sowing in a straight line, the rear wheel 22 undertakes the final soil compaction process after passing the sowing position, simplifying the requirements of the operation module. The robot does not need to have an additional compaction mechanism, effectively controlling equipment costs and reducing the size of the equipment.

[0044] As an improved specific implementation, the plowing mechanism 5 includes a pair of plowing ramps 51 and a plowing disc 52. The pair of plowing ramps 51 are vertically adjustable and symmetrically arranged at the front of the operating space. When the pair of plowing ramps 51 descend, they are arranged in a triangle, thereby scooping up the soil upon contact and dropping it backward. The plowing disc 52 is vertically adjustable and located behind the plowing ramps 51. When the plowing disc 52 descends, it contacts the soil and separates the soil scooped up by the plowing ramps 51 to both sides. The sowing mechanism 6 is located behind the plowing disc 52. The sowing mechanism 6 is used to sow seeds into the soil; the soil-pulling mechanism 7 includes a pair of soil-pulling plates 71, which are raised and lowered and symmetrically arranged at the rear of the operating space. When the pair of soil-pulling plates 71 descend, they are arranged in an inverted triangle. When the pair of soil-pulling plates 71 descend, they contact the soil and pull the sown soil towards the center. When the sowing robot is running to sow seeds, the plowing mechanism 5, the sowing mechanism 6, the soil-pulling mechanism 7, and the rear wheel 22 sequentially complete the loosening and separating of the soil, sowing, pulling and concentrating, and compacting of the soil.

[0045] like Figure 1 , 6As shown in Figures 7 and 8, during the sowing operation, the soil is first loosened by the front plowing mechanism 5. Specifically, it innovatively designs a pair of plowing ramps 51 arranged in a triangle. After descending to the working position, they maintain an inclined state with respect to the ground. As the robot moves, the triangular plowing ramps 51 scoop up the soil. Most of the soil accumulated on the plowing ramps 51 falls backward behind the plowing ramps 51, while a small portion disperses to both sides. Following the plowing ramps 51 is the plowing disc 52, which is supported on the ground and rotates as the robot moves, separating the soil loosened by the plowing ramps 51 to both sides. That is, the thickness of the plowing disc 52 presses out a groove for sowing. Then comes the sowing mechanism 6, which continuously outputs seeds that fall into the groove pressed out by the plowing disc 52. Next is the soil-dispensing mechanism 7, which features a pair of soil-dispensing plates 71 arranged in an inverted triangle. After descending to the working position, these plates maintain elastic contact with the soil, gathering it towards the center of the inverted triangle as they move. The two soil-dispensing plates 71 can be positioned with a slight gap between them or at a downward angle. As the soil volume increases, the gap between them or the plates 71 can be slightly lifted to move the soil backward, thus concentrating the soil and covering the seeds. Finally, the rear wheels 22 pass over the seed location, compacting the soil to achieve better coverage and control over soil density. This invention fulfills the sowing needs for small-scale, small-area planting of specific vegetable varieties, effectively implementing plowing, sowing, soil dispensing, and compaction operations, meeting specific user requirements, and ensuring seed sowing quality.

[0046] As an improved specific implementation, a pair of ploughing ramps 51 are swayably mounted on the lower part of the frame 1 via their respective first connecting rods 511. A first drive cylinder 512 is connected to the first connecting rod 511. When the two first connecting rods 511 are retracted, they form a figure-eight shape, thereby separating the pair of ploughing ramps 51. When the first drive cylinder 512 drives the first connecting rod 511 to swing downward, thereby causing the pair of ploughing ramps 51 to descend to contact the soil, the pair of first connecting rods 511 swing in parallel, and the pair of ploughing ramps 51 approach each other and are arranged in a triangle.

[0047] like Figure 6 , 7As shown in Figure 8, the representation of the structures in the figure has a perspective and simplification effect, and is mainly for illustrative purposes. By swinging the first connecting rod 511 and cooperating with the first driving cylinder 512, the two plowing ramps 51 are arranged in a V-shape when rising and retracting, which can effectively utilize the space on both sides for storage without interfering with the storage of the plowing disc 52. Furthermore, the way the first driving cylinder 512 is connected to the first connecting rod 511 from the side provides a relatively stable triangular support structure for the first driving cylinder 512 and the first connecting rod 511. This helps to maintain the plowing ramps 51 in stable contact with the soil. When the plowing ramps 51 are subjected to force during movement, the force can be effectively divided into two parts and transmitted to the relatively vertically arranged first connecting rod 511 and the inclined first driving cylinder 512 and shaft. This helps to disperse the force, reduce the shear force parallel to the ground, and improve the durability of the components. Preferably, the first connecting rod 51l can be configured as a structure with multiple sets of rods connected together, and elastic elements can be provided to realize the elastic state between the multiple sets of rods, thereby reducing the hard contact between the first connecting rod 511 and the ploughing ramp 51 and the ground.

[0048] As an improved specific implementation, the plowing disc 52 is swayably mounted on the lower part of the frame 1 via the second connecting rod 521. The second driving cylinder 522 is connected to the second connecting rod 521. The connection positions of the second connecting rod 521 and the two first connecting rods 511 to the lower part of the frame 1 are located on the front and rear sides respectively. Thus, when the second connecting rod 521 is retracted, the plowing disc 52 is located between the two first connecting rods 511, and the second connecting rod 521 is located between the two plowing ramps 51. When the second driving cylinder 522 drives the second connecting rod 521 to swing downward, the plowing disc 52 descends to contact the soil.

[0049] like Figure 6 , 7As shown in Figure 8, the representation of the structures in the figure has a perspective and simplification effect, and is mainly for illustrative purposes. By swinging the second connecting rod 521 in conjunction with the second drive cylinder 522, the plowing disc 52 is positioned between the two first connecting rods 511 and the plowing ramp 51 when it rises and retracts. Under the premise of not interfering with each other, this arrangement makes good use of the space below, allowing the first connecting rods 511 and the second connecting rod 521 to be swinged separately and to achieve good storage and lowering after swinging back and forth. The way the second drive cylinder 522 is inclined from the side to connect the second connecting rod 521 gives the second drive cylinder 522 and the second connecting rod 521 a relatively stable triangular support structure, which helps to keep the plowing disc 52 in stable contact with the soil. When the plowing disc 52 is subjected to force, the force can be effectively divided into two parts and transmitted to the relatively vertically arranged second connecting rod 521 and the inclined second drive cylinder 522 and shaft, which helps to disperse the force, reduce the shear force parallel to the ground, and improve the durability of the components. Preferably, the second link 521 can be configured as a structure with multiple sets of links connected together, and an elastic element can be provided to realize the elastic state between the multiple sets of links, thereby reducing the hard contact between the second link 521 and the plowing disc 52 and the ground.

[0050] As an improved specific implementation, a pair of soil-removing plates 71 are swayably mounted on the lower part of the frame 1 via their respective third connecting rods 711. A third drive cylinder 712 is connected to the third connecting rod 711. When the third drive cylinder 712 drives the third connecting rod 711 to swing downward, the soil-removing plate 71 will descend to contact the soil.

[0051] like Figure 6 , 7 As shown in Figure 8, the representation of the structures in the figure has a perspective and simplification effect, and is mainly for illustrative purposes. The way the third drive cylinder 712 is inclined from the side to connect to the third connecting rod 711 gives the third drive cylinder 712 and the third connecting rod 711 a relatively stable triangular support structure. This helps to keep the soil-removing plate 71 in stable contact with the soil. When the soil-removing plate 71 is subjected to force during movement, the force can be effectively divided into two parts and transmitted to the relatively vertically arranged third connecting rod 711 and the inclined third drive cylinder 712 and shaft. This helps to disperse the force, reduce the shear force parallel to the ground, and improve the durability of the components. Preferably, the third connecting rod 711 can be set as a structure with multiple sets of rods connected together, and elastic elements can be set to realize the elastic state between the multiple sets of rods, reducing the hard contact between the third connecting rod 711 and the soil-removing plate 71 and the ground.

[0052] As an improved specific implementation, the two third connecting rods 711 are in a figure-eight shape when retracted, which causes the pair of soil-dispensing plates 71 to separate. When the soil-dispensing plates 71 are retracted, they are located on both sides of the sowing mechanism 6. When the third drive cylinder 712 drives the third connecting rods 711 to swing downward, causing the pair of soil-dispensing plates 71 to descend to contact the soil, the pair of third connecting rods 711 swing in parallel, and the pair of soil-dispensing plates 71 approach each other and are arranged in an inverted triangle.

[0053] like Figure 6 , 7 As shown in Figure 8, by swinging the third connecting rod 711 and cooperating with the third drive cylinder 712, the soil-removing plate 71 is positioned on both sides of the sowing mechanism 6 when it rises and retracts. Under the premise of not interfering with each other, this arrangement makes good use of the space below, and allows the sowing mechanism 6 and the soil-removing mechanism 7 to overlap to a certain extent in structure, which can effectively utilize the space.

[0054] As an improved specific implementation, the sowing mechanism 6 includes a placement cavity 61 and a discharge roller 62. The placement cavity 61 is disposed on the frame 1. The lower cavity of the placement cavity 61 gradually narrows and forms an opening 63. A rotating cavity for arranging the discharge roller 62 is formed at the opening 63. The discharge roller 62 is arranged in the rotating cavity with matching dimensions and its axis is horizontally arranged to rotate. The surface of the discharge roller 62 has a feeding groove 64 for seeds to fall into and receive. When sowing, the discharge roller 62 is driven to rotate, causing the seeds in the placement cavity 61 to be sent out by the feeding groove 64 and fall from the lower end of the opening 63.

[0055] like Figure 6 As shown, the placement cavity 61 is used to place seeds, and a lid is provided at the top for preservation. The opening 63 forms a rotating cavity in the middle that matches the shape and size of the discharge roller 62. The two ends of the discharge roller 62 are rotatable. When seeds fall to the upper end of the opening 63, they are blocked by the discharge roller 62 and fall into the feeding trough 64 according to their size. During sowing, the discharge roller 62 is activated to rotate, drawing the seeds from the feeding trough 64 into the rotating cavity. As the rotation continues, the seeds fall and are sown when they reach the lower end of the opening 63. The discharge roller 62 can be configured to accommodate multiple sizes of the feeding trough 64, allowing for interchangeable feeding troughs. Different sizes of feeding troughs 64 are used depending on the type of vegetable to be planted, thus controlling the number of seeds sown.
