Description

Technical Field

[0001] This invention relates to the field of sowing and fertilization devices, specifically to a crop sowing and fertilization device. Background Technology

[0002] A sowing and fertilizing device is a mechanical device used in agricultural production to perform sowing and fertilizing operations simultaneously or separately. It can evenly sow seeds into the soil according to the preset plant spacing, row spacing and sowing depth. This is very important for ensuring the planting density and growing space of crops. When planting wheat, the sowing device can ensure that there are appropriate numbers of seeds per square meter, so that the wheat has enough light, water and nutrients during its growth process, and avoids the impact on yield due to over-dense or over-sparse planting. It is suitable for sowing a variety of crop seeds.

[0003] Patent CN208446006U discloses a crop seed sowing and fertilization device, including a platform, a sowing box, and a fertilizer box. The lower end of the platform is fixedly connected to the upper end of a support plate. The lower part of the support plate is rotatably connected to a first rotating shaft. The first rotating shaft is fixedly connected to the center of a first flywheel and a traveling wheel. The first flywheel is connected to a second flywheel via a first belt, and the second flywheel is connected to a third flywheel via a second belt. A third rotating shaft and a fourth rotating shaft, which are fixedly inserted at the center of the second and third flywheels, drive a first and a second material turntable to rotate, causing seeds and fertilizer to fall synchronously for sowing. The amount of fertilizer applied each time can be controlled by adjusting the size of the grooves on the rotating wheels. Simultaneously, the gear and rack structure on the soil-turning plate can adjust the soil-entry depth of the soil-turning plate. The structure is simple and compact, and the adjustable sowing method greatly improves its practicality.

[0004] The aforementioned device does not crush fertilizer during use. This means that when using a seeder for integrated sowing and fertilization, large fertilizer particles may accumulate in certain areas while being less distributed in others. This results in significant differences in fertilizer concentration in different parts of the soil, and uneven contact between crop roots and fertilizer during growth. Roots near areas with dense fertilizer particles may be damaged by high concentrations of fertilizer, leading to root burn and affecting crop growth space. Therefore, a crop sowing and fertilization device is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a crop sowing and fertilization device to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a crop sowing and fertilization device, including an electric cart, a mixing device on the top of the electric cart, a uniform feeding device at the bottom of the electric cart, and a stone removal device on the top of the electric cart; the mixing device includes a fertilizer tank, a motor, a sieve plate, a reciprocating screw, a connecting block, a fixing plate, a hinge rod, a rolling roller, a cross fan, and a scraper; the fertilizer tank is fixedly installed on the top of the electric cart, the motor is fixedly connected to the top of the fertilizer tank, and the sieve plate is fixedly installed on... The inner wall of the fertilizer hopper is fitted with a reciprocating screw fixedly connected to the output end of a motor. A connecting block is movably connected to the circumferential surface of the reciprocating screw. A fixing plate is fixedly connected to the bottom of the connecting block. A hinge rod is hinged to the inner wall of the fixing plate via a torsion spring. A crushing roller is fixedly installed on the outer wall of the hinge rod. After the crushing roller crushes the fertilizer, the fertilizer particles become smaller. During sowing, the smaller fertilizer particles can be more evenly distributed in the soil. Compared with larger fertilizer particles, smaller fertilizer particles have a larger surface area, which makes it easier for the fertilizer to react with water in the soil. This contact accelerates the dissolution of fertilizer and the release of nutrients. For some slow-release fertilizers, crushing allows for a nutrient release rate that better meets the needs of crop growth, avoiding situations where crops cannot absorb sufficient nutrients during critical growth stages due to excessively large fertilizer particles and slow nutrient release. The cross-shaped fan is fixedly connected to the circumferential surface of the reciprocating screw, the scraper is fixedly connected to the bottom of the cross-shaped fan, the circumferential surface of the crushing roller contacts the top of the sieve plate, the inner wall of the sieve plate is rotatably connected to the circumferential surface of the reciprocating screw, and the circumferential surface of the reciprocating screw contacts the fertilizer. The inner wall of the bucket is rotatably connected, and the outer wall of the scraper contacts the inner wall of the fertilizer bucket. When the cross fan rotates, it causes the seeds and fertilizer particles to tumble and collide continuously inside the bucket. This movement can break up any possible agglomeration of seeds and fertilizer, allowing them to come into more full contact at the microscopic level. For seeds and fertilizers with large differences in particle size, the stirring of the cross fan can prevent small fertilizer particles from being buried by large seeds, ensuring that each seed is evenly surrounded by fertilizer, thereby providing a balanced nutrient environment for seed germination and growth.

[0007] Preferably, the uniform feeding includes a guide block one, a guide block two, a moving plate, a hose, a concentrator box, an opening plate, and a support plate one. The guide block one is fixedly connected to the bottom of the scraper, the moving plate is slidably connected to the inner wall of the fertilizer tank, the guide block two is fixedly connected to the top of the moving plate, the hose is fixedly installed on the inner wall of the fertilizer tank, the concentrator box is fixedly connected to the circumferential surface of the hose, the top of the opening plate contacts the electric trolley, and the support plate one is fixedly connected to the bottom of the electric trolley. The uniform feeding also includes a spring one, a square plate, a guide plate one, a guide plate two, a pressure plate, a fixing plate two, and a tilting spring. A plate and a second spring are used. The first spring is fixedly connected to the bottom of the electric trolley. The square plate is fixedly connected to the bottom of the moving plate. The first guide plate is fixedly connected to the right side of the square plate, and the second guide plate is fixedly connected to the right side of the opening plate. The movement of the second guide plate causes the opening plate to move and open, clearing away the turned soil at the bottom and allowing the seeds to enter the pit. This process is like creating a precise landing channel for the seeds. In this way, the seeds can accurately fall into the pre-turned soil pit, avoiding scattering in unsuitable locations, such as landing on clods of soil or in hard, unturned soil areas. In crop cultivation, such as vegetable planting, where precise sowing depth and location are crucial, this precise sowing method ensures seeds germinate at the appropriate depth and in loose soil, facilitating better seed-soil contact and thus improving germination rates. The pressure plate is fixedly connected to the front of the guide block two, and the fixing plate two is fixedly connected to the inner wall of the fertilizer tank. The rocker arm is hinged to the inner wall of the fixing plate two, allowing the rocker arm to open and evenly drop the mixed seeds and fertilizer into the hose. This helps to precisely control the sowing rate. In agricultural sowing, sowing density is a key factor affecting crop yield and quality. Key factors include the ability of seeds and fertilizers to enter the sowing pipes in a predetermined ratio and quantity through this uniform dispensing method, thereby ensuring a relatively consistent sowing density per unit area in the field. The second spring is fixedly connected to the right side of the first support plate, the right side of the first guide plate contacts the left side of the second guide plate, the inner wall of the square plate is slidably connected to the flexible hose, the circumferential surface of the flexible hose is fixedly connected to the inner wall of the electric trolley, the bottom of the first spring is fixedly connected to the top of the square plate, the right side of the second spring is fixedly connected to the left side of the opening plate, and the outer wall of the moving plate is slidably connected to the inner wall of the electric trolley.

[0008] Preferably, the stone removal device includes a horizontal plate, a lever plate, a movable column, a sliding plate, a spring, a support plate, a fixing plate, and a vertical plate. The horizontal plate is fixedly connected to the right side of the opening plate. The movement of the horizontal plate drives the lever plate to reciprocate, thus dislodging stones from the turned soil. This reduces damage to crop roots. In agricultural planting, stones in the soil can hinder crop root growth. When the horizontal plate moves and drives the lever plate to reciprocate, separating the stones from the turned soil, a relatively clean and unobstructed growth environment is provided for the crop roots. For root crops such as radishes and carrots, if the roots encounter stones during growth, it may cause root deformation and branching, affecting crop quality and yield. After removing the stones, the roots can grow downwards smoothly, which is conducive to forming a complete and regular root shape. The lever plate is fixed. Connected to the right side of the horizontal plate, the movable column is fixedly connected to the top of the sliding plate. The sliding plate contacts the top of the electric trolley. The third spring is fixedly connected to the rear of the sliding plate. The second support plate is fixedly connected to the top of the electric trolley. The third fixed plate is slidably connected to the inner wall of the electric trolley. The vertical plate is fixedly connected to the bottom of the third fixed plate. The top of the third fixed plate is fixedly connected to the bottom of the sliding plate. The rear of the third spring is fixedly connected to the front of the second support plate. The circumferential surface of the movable column is slidably connected to the inner wall of the electric trolley. The circumferential surface of the movable column is slidably connected to the inner wall of the sliding plate. The movement of the movable column and the sliding of the sliding plate cause the sliding plate to move left and right. The movement of the sliding plate drives the third fixed plate to move. The movement of the third fixed plate drives the vertical plate to move. The movement of the vertical plate pushes the displaced stones onto the ditch, making the displaced stones easier to clean up later.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This crop sowing and fertilization device, through the coordinated operation of a fertilizer tank, motor, sieve plate, reciprocating screw, connecting block, fixed plate, hinge rod, roller, cross fan, and scraper, uses a roller to crush the fertilizer, resulting in smaller fertilizer particles. During sowing, these smaller particles can be more evenly distributed in the soil. Compared to larger particles, smaller particles have a larger surface area, making it easier for the fertilizer to come into contact with water in the soil, thus accelerating the dissolution and nutrient release. For some slow-release fertilizers, crushing them allows the nutrient release rate to better meet the needs of crop growth, avoiding the problem of excessively large fertilizer particles hindering nutrient release. In cases where slow release of nutrients prevents crops from absorbing sufficient nutrients during critical growth stages, the rotation of the cross-shaped fan creates a dynamic stirring effect within the fertilizer container. As the fan rotates, it causes the seeds and fertilizer particles to tumble and collide continuously within the container. This movement breaks up any potential agglomeration of seeds and fertilizer, allowing them to come into more thorough contact at the microscopic level. For seeds and fertilizers with significant differences in particle size, the cross-shaped fan's stirring prevents small fertilizer particles from being buried by large seeds, ensuring that each seed is evenly surrounded by fertilizer, thus providing a balanced nutrient environment for seed germination and growth.

[0010] 2. This crop sowing and fertilization device, through the coordinated operation of guide block one, guide block two, moving plate, hose, concentrator box, opening plate, support plate one, spring one, square plate, guide plate one, guide plate two, pressure plate, fixing plate two, rocker plate, and spring two, allows the rocker plate to open, evenly dropping the mixed seeds and fertilizer into the hose. This helps to precisely control the sowing rate. In agricultural sowing, sowing density is a crucial factor affecting crop yield and quality. Through this uniform delivery method, seeds and fertilizer can enter the sowing pipe according to a predetermined ratio and quantity, thereby ensuring a relatively consistent sowing density per unit area in the field. The guide plate moves, causing the opening plate to open and loosen the turned soil at the bottom, allowing the seeds to fall into the pit. This process is like creating a precise landing channel for the seeds. In this way, the seeds can accurately fall into the pre-turned soil pit, avoiding the seeds from scattering in unsuitable places, such as falling on clods of soil or hard soil areas that have not been tilled. In the cultivation of some crops with high requirements for sowing depth and positional accuracy, such as vegetable cultivation, this precise sowing method can ensure that the seeds take root and germinate in a suitable depth and loose soil environment, which is conducive to better contact between the seeds and the soil, thereby improving the germination rate.

[0011] 3. This crop sowing and fertilizing device, through the coordinated operation of a horizontal plate, a lever plate, a moving column, a sliding plate, a spring, a support plate, a fixed plate, and a vertical plate, moves the horizontal plate, causing the lever plate to reciprocate. This dislodges stones from the turned soil, reducing damage to crop roots. In agricultural planting, stones in the soil can hinder crop root growth. When the horizontal plate moves and the lever plate reciprocates, separating the stones from the turned soil, a relatively clean and unobstructed growth environment is provided for crop roots, such as for radishes. For root crops such as turnips and carrots, encountering stones during root growth can cause root deformation and branching, affecting crop quality and yield. Removing the stones allows the roots to grow downwards smoothly, promoting the formation of complete and regular root shapes. The movement of the sliding plate moves the moving column, which in turn slides against the sliding chute, causing the chute to move left and right. This movement of the chute then moves the fixed plate, which in turn moves the vertical plate, which in turn moves the removed stones onto the ditch, facilitating subsequent cleaning.

Detailed Implementation

[0014] 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.

[0015] Please see Figures 1-8One embodiment of the present invention is as follows: a crop sowing and fertilization device, including an electric cart 1, a mixing device 2 on the top of the electric cart 1, a uniform feeding device 3 on the bottom of the electric cart 1, and a stone removal device 4 on the top of the electric cart 1; the mixing device 2 includes a fertilizer tank 201, a motor 202, a sieve plate 203, a reciprocating screw 204, a connecting block 205, a fixing plate 206, a hinge rod 207, a rolling roller 208, a cross fan 209, and a scraper 210; the fertilizer tank 201 is fixedly installed on the top of the electric cart 1, the motor 202 is fixedly connected to the top of the fertilizer tank 201, the sieve plate 203 is fixedly installed on the inner wall of the fertilizer tank 201, the reciprocating screw 204 is fixedly connected to the output end of the motor 202, and the connecting block 205 is fixedly installed on the top of the electric cart 1. 5. A movable connection is made to the circumferential surface of the reciprocating screw 204. A fixed plate 206 is fixedly connected to the bottom of the connecting block 205. A hinge rod 207 is hinged to the inner wall of the fixed plate 206 via a torsion spring. A crushing roller 208 is fixedly installed on the outer wall of the hinge rod 207. When the device is started, the motor 202 drives the reciprocating screw 204 to rotate. The cross-shaped spiral groove on the reciprocating screw 204 drives the connecting block 205 to move. The movement of the connecting block 205 drives the fixed plate 206 to move. The movement of the fixed plate 206 drives the hinge rod 207 to move. The movement of the hinge rod 207 drives the crushing roller 208 to move. The movement of the crushing roller 208 crushes the fertilizer and mixes it with the seeds inside the fertilizer hopper 201 for sowing, improving the utilization rate of the fertilizer. 8. After crushing the fertilizer, the fertilizer particles become smaller. During the sowing process, the smaller fertilizer particles can be more evenly distributed in the soil. Compared with larger fertilizer particles, smaller fertilizer particles have a larger surface area, which makes it easier for the fertilizer to come into contact with water in the soil, thereby accelerating the dissolution of the fertilizer and the release of nutrients. For some slow-release fertilizers, crushing can make the nutrient release rate more in line with the needs of crop growth, avoiding the situation where crops cannot absorb enough nutrients in time during the critical growth period due to excessively large fertilizer particles and slow nutrient release. The cross fan 209 is fixedly connected to the circumferential surface of the reciprocating screw 204, and the scraper 210 is fixedly connected to the bottom of the cross fan 209. The circumferential surface of the rolling roller 208 contacts the top of the sieve plate 203. The inner wall of the fertilizer container 201 is rotatably connected to the circumferential surface of the reciprocating screw 204, which in turn is rotatably connected to the inner wall of the fertilizer container 201. The outer wall of the scraper 210 contacts the inner wall of the fertilizer container 201. The rotation of the reciprocating screw 204 drives the cross fan 209 to rotate, which in turn drives the scraper 210 to rotate. The rotation of the cross fan 209 makes the seeds and fertilizer mix more evenly. The scraper 210 removes the fertilizer adhering to the inner wall of the fertilizer container 201. The rotation of the cross fan 209 creates a dynamic stirring effect within the fertilizer container 201. When the cross fan 209 rotates, it causes the seeds and fertilizer particles to tumble and collide continuously within the container. This movement breaks up any potential agglomeration of the seeds and fertilizer.This allows for more thorough contact at the microscopic level. For seeds and fertilizers with significant differences in particle size, the mixing action of the cross-shaped fan 209 prevents small fertilizer particles from being buried by large seeds, ensuring that each seed is evenly surrounded by fertilizer, thus providing a balanced nutrient environment for seed germination and growth.

[0016] The uniform feeding mechanism 3 includes a guide block 301, a guide block 302, a moving plate 303, a hose 304, a collection box 305, an opening plate 306, and a support plate 307. The guide block 301 is fixedly connected to the bottom of the scraper 210. The moving plate 303 is slidably connected to the inner wall of the fertilizer tank 201. The guide block 302 is fixedly connected to the top of the moving plate 303. The hose 304 is fixedly installed on the inner wall of the fertilizer tank 201. The collection box 305 is fixedly connected to the circumference of the hose 304. The top of the opening plate 306 contacts the electric trolley 1. The support plate 307 is fixedly connected to the bottom of the electric trolley 1. The uniform feeding mechanism 3 also includes a spring 308, a square plate 309, a guide plate 310, a guide plate 311, a pressure plate 312, and a fixed... Board 2 (313), rocker 314, spring 2 (315), and spring 1 (308) are fixedly connected to the bottom of the electric trolley 1. Square board 309 is fixedly connected to the bottom of the moving board 303. Guide board 1 (310) is fixedly connected to the right side of square board 309. Guide board 2 (311) is fixedly connected to the right side of the opening board 306. The movement of the moving board 303 moves the square board 309, which in turn moves guide board 1 (310). When guide board 1 (310) moves, it contacts guide board 2 (311), causing guide board 2 (311) to move to the right. This movement of guide board 2 (311) causes the opening board 306 to open, clearing away the turned soil at the bottom and allowing the seeds to enter the pit. This process is like creating a precise landing channel for the seeds. In this method, seeds can accurately fall into pre-turned soil pits, avoiding scattering in unsuitable locations, such as on clods of soil or in hard, uncultivated areas. In crop cultivation, such as vegetable planting, where precise sowing depth and location are crucial, this precise method ensures seeds germinate at the appropriate depth and in loose soil, facilitating better seed-soil contact and improving germination rates. The pressure plate 312 is fixedly connected to the front of the guide block 302, and the fixing plate 313 is fixedly connected to the inner wall of the fertilizer tank 201. The rocker arm 314 is hinged to the inner wall of the fixing plate 313. Rotation of the scraper 210 drives the guide block 301 to rotate, causing it to interact with the guide block 302. Contact causes guide block 302 to move downwards, which in turn moves moving plate 303 downwards. This movement of guide block 302 then moves pressure plate 312, which in turn moves rocker plate 314. This rocker plate 314 opens, allowing the mixed seeds and fertilizer to fall evenly into hose 304. This helps to precisely control the sowing rate. In agricultural sowing, sowing density is a crucial factor affecting crop yield and quality. This uniform distribution method ensures that seeds and fertilizer enter the sowing pipe according to a predetermined ratio and quantity, thus guaranteeing a relatively consistent sowing density per unit area in the field. For corn sowing, a suitable planting density ensures that each corn plant has sufficient space to absorb sunlight, water, and nutrients.To avoid excessive competition for resources due to overly dense planting or waste of land resources due to overly sparse planting, spring 2 315 is fixedly connected to the right side of support plate 1 307. The right side of guide plate 1 310 contacts the left side of guide plate 2 311. The inner wall of square plate 309 is slidably connected to hose 304. The circumferential surface of hose 304 is fixedly connected to the inner wall of electric trolley 1. The bottom of spring 1 308 is fixedly connected to the top of square plate 309. The right side of spring 2 315 is fixedly connected to the left side of opening plate 306. The outer wall of moving plate 303 is slidably connected to the inner wall of electric trolley 1.

[0017] Working Principle: When the device is started, the motor 202 drives the reciprocating screw 204 to rotate. The cross-shaped spiral groove on the reciprocating screw 204 drives the connecting block 205 to move. The movement of the connecting block 205 drives the fixed plate 206 to move. The movement of the fixed plate 206 drives the hinge rod 207 to move. The movement of the hinge rod 207 drives the crushing roller 208 to move. The crushing roller 208 crushes the fertilizer and mixes it with the seeds inside the fertilizer tank 201 for sowing, improving the utilization rate of the fertilizer. After the crushing roller 208 crushes the fertilizer, the fertilizer particles become smaller. During the sowing process, the smaller fertilizer particles can be more evenly distributed in the soil. Compared with larger fertilizer particles, smaller fertilizer particles have a larger surface area, which makes it easier for the fertilizer to come into contact with water in the soil, thereby accelerating the dissolution of the fertilizer and the release of nutrients. For some slow-release fertilizers, crushing makes the nutrient release rate more suitable for the growth needs of crops, avoiding the problem of excessively large fertilizer particles. In cases where slow nutrient release prevents crops from absorbing sufficient nutrients during critical growth stages, the reciprocating screw 204 rotates, driving the cross-shaped fan 209 to rotate. This rotation, in turn, drives the scraper 210, ensuring a more even mixture of seeds and fertilizer. The scraper 210 removes fertilizer adhering to the inner wall of the fertilizer container 201. The rotation of the cross-shaped fan 209 creates a dynamic stirring effect within the container, causing seeds and fertilizer particles to tumble and collide. This movement breaks up any potential agglomeration, allowing for more thorough contact at the microscopic level. For seeds and fertilizers with significant size differences, the stirring action of the cross-shaped fan 209 prevents smaller fertilizer particles from being buried by larger seeds, ensuring each seed is evenly surrounded by fertilizer, thus providing a balanced nutrient environment for germination and growth.

[0018] The rotation of scraper 210 drives guide block 301 to rotate. When guide block 301 rotates, it contacts guide block 302, causing guide block 302 to move downwards. This downward movement of guide block 302 drives moving plate 303 downwards, which in turn moves pressure plate 312. Pressure plate 312 then moves rocker plate 314, causing rocker plate 314 to open and evenly distribute the mixed seeds and fertilizer into hose 304. This helps to precisely control the seeding rate. In agricultural sowing, seeding density is a crucial factor affecting crop yield and quality. This uniform distribution method ensures that seeds and fertilizer enter the sowing pipe according to a predetermined ratio and quantity, thus guaranteeing a relatively consistent seeding density per unit area in the field. For corn sowing, a suitable planting density ensures that each corn plant has sufficient space to absorb sunlight, water, and nutrients, preventing overcrowding and excessive competition for resources. Excessive or insufficient sowing wastes land resources. The movement of the movable plate 303 moves the square plate 309, which in turn moves the guide plate 310. When the guide plate 310 moves, it contacts the guide plate 311, causing the guide plate 311 to move to the right. This movement of the guide plate 311 then moves the opening plate 306, opening up the prepared soil at the bottom and allowing the seeds to fall into the pit. This process is like creating a precise landing channel for the seeds. In this way, the seeds can accurately fall into the pre-prepared soil pit, avoiding scattering in unsuitable locations, such as on clods of soil or in hard, uncultivated areas. In crop cultivation, such as vegetable cultivation, where precise sowing depth and location are crucial, this precise sowing method ensures that seeds germinate in the appropriate depth and loose soil environment, promoting better contact between the seeds and the soil and thus improving the germination rate.

[0019] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the stone removal device 4 includes a horizontal plate 401, a lever plate 402, a movable column 403, a sliding plate 404, a spring 405, a support plate 406, a fixing plate 407, and a vertical plate 408. The horizontal plate 401 is fixedly connected to the right side of the opening plate 306, and the lever plate 402 is fixedly connected to the right side of the horizontal plate 401. The movement of the opening plate 306 drives the horizontal plate 401 to move, and the movement of the horizontal plate 401 drives the lever plate 402 to reciprocate, thereby dislodging the stones in the turned soil. In agricultural planting, stones in the soil can hinder crop root growth. When the horizontal plate 401 moves, it drives the prying plate 402 to reciprocate, separating the stones from the turned soil. This provides a relatively clean and unobstructed growing environment for the crop roots. For root crops like radishes and carrots, encountering stones during root growth can cause root deformation and branching, affecting crop quality and yield. Removing the stones allows the roots to grow downwards smoothly, which is beneficial. To form a complete and regular root shape, the movable column 403 is fixedly connected to the top of the lever plate 402, the slide plate 404 contacts the top of the electric cart 1, the spring 405 is fixedly connected to the rear of the slide plate 404, the support plate 406 is fixedly connected to the top of the electric cart 1, the fixed plate 407 is slidably connected to the inner wall of the electric cart 1, the vertical plate 408 is fixedly connected to the bottom of the fixed plate 407, the top of the fixed plate 407 is fixedly connected to the bottom of the slide plate 404, and the rear of the spring 405 is fixedly connected to the front of the support plate 406. The circumferential surface of the movable column 403 is slidably connected to the inner wall of the electric trolley 1, and the circumferential surface of the movable column 403 is slidably connected to the inner wall of the sliding plate 404. The movable column 403 is moved by the movement of the lever plate 402, and the movable column 403 slides with the sliding plate 404, causing the sliding plate 404 to move left and right. The movement of the sliding plate 404 causes the fixed plate 3 407 to move, and the movement of the fixed plate 3 407 causes the vertical plate 408 to move. The movement of the vertical plate 408 pushes the displaced stones onto the ditch, making the displaced stones easier to clean up later.

[0020] Working principle: The movement of the opening plate 306 moves the horizontal plate 401, which in turn moves the lever 402, causing it to reciprocate and dislodge stones from the turned soil. This reduces the damage to crop roots caused by stones. In agricultural planting, stones in the soil can hinder crop root growth. When the horizontal plate 401 moves and the lever 402 reciprocates, separating the stones from the turned soil, a relatively clean and unobstructed growing environment is provided for the crop roots. For root crops such as radishes and carrots, if the roots encounter stones during growth... Removing stones can cause root deformation and branching, affecting crop quality and yield. Removing stones allows roots to grow downwards smoothly, which is beneficial for forming a complete and regular root shape. The movement of the sliding plate 402 drives the movement of the moving column 403. The movement of the moving column 403 slides against the sliding plate 404, causing the sliding plate 404 to move left and right. The movement of the sliding plate 404 drives the movement of the fixed plate 407. The movement of the fixed plate 407 drives the movement of the vertical plate 408. The movement of the vertical plate 408 pushes the removed stones onto the ditch, making the removed stones easier to clean up later.
