Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to an automatic agricultural organic fertilizer spreading device that facilitates automatic adjustment of the spreading soil layer. Background Technology

[0002] In current agricultural planting processes, the application of organic fertilizer is a crucial step in ensuring high crop yields and increased income. Organic fertilizer not only supplements crop growth with nitrogen, phosphorus, potassium, and various trace elements, but also improves soil structure, enhances soil fertility, and improves water and fertilizer retention capacity. It is a core operational step in promoting agricultural quality and efficiency and achieving green and ecological planting. The quality of its application directly affects crop growth, seed setting rate, and final yield and quality. Compared to chemical fertilizers, organic fertilizers are derived from natural raw materials such as animal and plant residues and livestock manure. They provide comprehensive nutrients and release them slowly and gently, meeting the nutrient needs of crops at different growth stages without disrupting the soil's pH balance. This avoids the problems of soil compaction and soil fertility decline caused by long-term application of chemical fertilizers, making it an ideal fertilizer source that balances high crop yields and ecological planting.

[0003] As a crucial step in ensuring the effectiveness of organic fertilizer, sowing directly determines whether nutrients can be efficiently absorbed by crop roots, thus affecting planting yields and the sustainability of agricultural production. The importance of organic fertilizer sowing is particularly prominent in field grain crops, cash fruit and vegetable crops, and specialty planting industries. For example, in grain crop cultivation, even and sufficient organic fertilizer promotes robust root development, enhances resistance to lodging and pests, and lays a solid foundation for stable and high yields. In fruit and vegetable cultivation, precise sowing of organic fertilizer can improve fruit sweetness, color, and taste, increasing the commercial value of agricultural products. In ecological planting bases, standardized organic fertilizer sowing is a core requirement for achieving green and organic certification.

[0004] However, although simple mechanical spreading is an improvement over manual spreading, it can only achieve surface spreading. Organic fertilizer is directly exposed on the soil surface, which is easily washed away by rain and eroded by wind, resulting in nutrient loss. At the same time, it is difficult to carry out in conjunction with the tillage and plowing process. Plowing must be completed first before spreading. The multi-step operation not only increases the operation time, but also makes it impossible for organic fertilizer to be accurately buried in the tillage soil layer. The crop roots cannot absorb it quickly, and the fertilizer utilization rate is greatly reduced.

[0005] Based on this, the present invention discloses an automatic agricultural organic fertilizer spreading device that facilitates automatic adjustment of the spreading soil layer. Summary of the Invention

[0006] To address the problems mentioned in the background art, although simple mechanical spreading is an improvement over manual methods, it mostly only achieves surface spreading, leaving organic fertilizer directly exposed on the soil surface. This makes it susceptible to erosion by rainwater and wind, resulting in nutrient loss. Furthermore, it is difficult to coordinate with tillage and plowing processes, requiring plowing first. These multiple steps not only increase work time but also prevent the organic fertilizer from being accurately buried in the tilled soil layer, hindering rapid absorption by crop roots and significantly reducing fertilizer utilization. Therefore, this invention provides an automatic agricultural organic fertilizer spreading device that facilitates automatic adjustment of the spreading soil layer. The device includes a weighing connecting plate, with a second connecting rod symmetrically fixedly connected to the inner side of the weighing connecting plate, and a weighing connecting rod rotatably connected to the outer side of the second connecting rod. The weighing connecting rod is rotatably connected to the inner side of the end away from the second connecting rod. A device connector is fixedly connected to the outer side of the two first connecting rods. Device mounting holes are symmetrically opened on the inner side of the device connector. A material distribution trough is fixedly connected to the end of the weighing connecting plate away from the device connector. A discharge trough is fixedly connected to the upper end of the material distribution trough. Multiple sets of hollow limiting frames are fixedly connected to the lower end of the material distribution trough. A plowing grab is sleeved on the outer side of the hollow limiting frame. Multiple material distribution holes are opened on the inner side of the material distribution trough. A discharge hole is opened at the lower end of the plowing grab. The plowing grab, hollow limiting frame, and material distribution holes are internally interconnected. A discharge assembly is provided on the inner side of the material distribution trough. A lifting assembly is provided between the plowing grab and the material distribution trough.

[0007] As a further improvement to this technical solution, the feeding assembly includes a rotating rod and a semi-circular dispensing spoon. The rotating rod is rotatably connected to the inner side of the dispensing groove, and multiple sets of semi-circular dispensing spoons are rotatably connected to the inner side of the dispensing hole. The semi-circular dispensing spoons are fixedly connected to the rotating rod.

[0008] As a further improvement to this technical solution, wheel assemblies are symmetrically arranged at both ends of the material distribution trough. A wheel rod is installed in the middle of the wheel assembly near the end of the material distribution trough, and the end of the wheel rod away from the wheel assembly is rotatably connected to the material distribution trough.

[0009] As a further improvement to this technical solution, the lifting assembly includes a mounting frame, a fixed connecting frame, a lifting plate, a first row of serrated grooves, a snap-fit ​​plate, and a second row of serrated grooves. The end of the material distribution trough near the device connector is symmetrically and fixedly connected to the mounting frame, and the ends of the multiple sets of plowing grippers are fixedly connected to the fixed connecting frame. The upper end of the fixed connecting frame is fixedly connected to the lifting plate. The end of the lifting plate is provided with the first row of serrated grooves. A snap-fit ​​plate is provided at one symmetrical end of the lifting plate. The end of the snap-fit ​​plate near the lifting plate is provided with the second row of serrated grooves. The snap-fit ​​plate and the second row of serrated grooves mesh with each other.

[0010] As a further improvement to this technical solution, mounting blocks are symmetrically fixedly connected to both ends of the snap-fit ​​plate. A first threaded hole is opened on the inner side of the mounting block, and a second threaded hole is opened on the inner side of the mounting bracket. The mounting blocks are located on the inner side of the mounting bracket and are interlocked with each other.

[0011] As a further improvement to this technical solution, the two ends of the first equal-row sawtooth groove are symmetrically fixedly connected with limiting blocks, and the inner side of the mounting bracket is provided with limiting grooves. The two limiting blocks are respectively located inside the limiting grooves and are slidably connected to the limiting grooves.

[0012] As a further improvement to this technical solution, multiple sets of material pouring blocks are fixedly connected to the inner side of the material distribution trough.

[0013] As a further improvement to this technical solution, a soil-breaking block is fixedly connected to the end of the plowing grabber.

[0014] As a further improvement to this technical solution, multiple sets of soil-binding heads are fixedly connected to the outer side of the wheel assembly.

[0015] As a further improvement to this technical solution, one end of the rotating rod passes through the material distribution trough and is fixedly connected to a first gear, and a second gear is fixedly connected to the outside of the wheel rod, with the first gear and the second gear meshing together.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this automatic agricultural organic fertilizer spreading device that facilitates automatic adjustment of the spreading soil layer, after the material falls into the dispensing trough into the dispensing trough, it is guided and concentrated by the inclined surface of the pouring block. Then, the rotation of the wheel drives the semi-circular dispensing spoon to rotate, and with the plowing and shaking of the device, the material is evenly distributed. It is accurately conveyed to the inside of the plowing grab through the dispensing hole and the hollow limit frame. At the same time, the soil-breaking block at the end of the plowing grab breaks open the regular soil groove, and the material is finally discharged directly into the soil groove through the dispensing hole, realizing precise quantitative fertilization, avoiding material waste, facilitating crop absorption, and improving fertilization effect.

[0017] 2. In this automatic agricultural organic fertilizer spreading device that facilitates automatic adjustment of the spreading soil layer, the first row of sawtooth grooves and the second row of sawtooth grooves of the snap-fit ​​plate are matched in size and precisely meshed. Relying on the sawtooth meshing structure, the height of the lifting plate is accurately positioned. The meshing surfaces fit tightly, which can effectively resist the vibration and impact and soil reaction force during operation, prevent the lifting plate from loosening and shifting, ensure that the plowing depth remains consistent during operation, and adjust the height. The operation is convenient and efficient. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0023] like Figures 1-6As shown, this embodiment provides a tractor-driven integrated plowing and fertilizing device, including a weighing connecting plate 101. A second connecting rod 105 is symmetrically fixedly connected to the inner side of the weighing connecting plate 101. A weighing connecting rod 102 is rotatably connected to the outer side of the second connecting rod 105. A first connecting rod 104 is rotatably connected to the inner side of the end of the weighing connecting rod 102 away from the second connecting rod 105. A device connector 103 is fixedly connected to the outer sides of both first connecting rods 104. Device mounting holes 106 are symmetrically provided on the inner side of the device connector 103. The device connector 103 is installed at the rear of the tractor through the device mounting holes 106 and fasteners such as bolts, achieving linkage between the device and the tractor. Simultaneously, the rotatable connection structure of the weighing connecting rod 102, the first connecting rod 104, and the second connecting rod 105 can adapt to slight bumps during tractor movement and buffer the force. The weighing connecting plate 101 is fixedly connected to a material distribution trough 107 at one end away from the device connector 103. A discharge trough 108 is fixedly connected to the upper end of the material distribution trough 107. The discharge trough 108 is used to hold the fertilizer to be applied, providing a stable material reserve for fertilization operations. Its opening size is adapted to the upper end of the material distribution trough 107 to ensure that the material can fall completely into the material distribution trough 107. Multiple sets of pouring blocks 701 are fixedly connected to the inner side of the material distribution trough 107. The pouring blocks 701 are arranged at an incline. Through the guide of the inclined surface of the pouring blocks 701, the material can be better concentrated in the rotation area of ​​the subsequent discharge component. At the same time, the device will generate slight vibration during the plowing process of the tractor. The vibration effect, combined with the guide of the pouring blocks 701, can effectively avoid material accumulation and make the semi-circular dispensing spoon 202 dispense the material more evenly. Multiple hollow limiting frames 110 are fixedly connected to the lower end of the material distribution trough 107. A plowing grab 109 is movably fitted onto the outer side of each hollow limiting frame 110. The plowing grab 109 cuts into the soil to break up and plow the ground. The hollow limiting frames 110 provide axial limiting and radial guidance for the plowing grab 109, preventing it from shifting during operation. Simultaneously, the hollow interior of the limiting frames 110 serves as a material flow channel, allowing material in the material distribution trough 107 to smoothly enter the inner side of the plowing grab 109. To enhance the soil-breaking effect, a soil-breaking block 801 is fixedly connected to the end of the plowing grab 109. The soil-breaking block 801 is made of high-manganese steel wear-resistant material and has a sharp end, reducing resistance when cutting into the soil, improving soil-breaking efficiency, and extending service life. The inner side of the material distribution trough 107 has multiple material distribution holes 111; the lower end of the plowing grab 109 has a discharge hole 112. The plowing grab 109, the hollow limiting frame 110, and the material distribution holes 111 are interconnected. The inner side of the material distribution trough 107 is equipped with a discharge assembly. When the plowing grab 109 breaks up the soil, the material is quantitatively distributed through the discharge assembly. The material first flows into the hollow limiting frame 110 through the material distribution holes 111, then flows to the inner side of the plowing grab 109 through the hollow limiting frame 110, and finally is precisely discharged into the soil trough broken up by the plowing grab 109 through the discharge hole 112, realizing simultaneous plowing and fertilization. To enable the plowing grab 109 to be raised and lowered, thereby adjusting the plowing depth according to the crop cultivation needs, a lifting assembly is provided between the plowing grab 109 and the material distribution trough 107.

[0024] To ensure that the material is evenly fed into the soil, the material dispensing assembly includes a rotating rod 201 and a semi-circular dispensing spoon 202. The rotating rod 201 is horizontally rotatably connected to the inner side of the dispensing trough 107, and multiple sets of semi-circular dispensing spoons 202 are rotatably connected to the inner side of the dispensing holes 111. The semi-circular dispensing spoons 202 are fixedly connected to the rotating rod 201. By rotating the rotating rod 201, all the semi-circular dispensing spoons 202 are rotated synchronously. When the semi-circular dispensing spoons 202 rotate, they can evenly scrape the material concentrated inside the dispensing trough 107 into each dispensing hole 111, realizing on-demand dispensing. The semi-circular structure can avoid material residue and improve dispensing stability.

[0025] To ensure smooth movement of the device during plowing and prevent tilting from affecting plowing depth and fertilization accuracy, wheel assemblies 301 are symmetrically arranged at both ends of the distribution trough 107. A wheel rod 302 is installed at the center of the wheel assembly 301 near the end of the distribution trough 107, and the ends of the wheel rods 302 away from the wheel assembly 301 are rotatably connected to the distribution trough 107. The two wheel rods 302 provide symmetrical support for the distribution trough 107, balancing the overall weight of the device and adapting to different terrains. To increase the friction between the wheel assembly 301 and the soil and prevent slippage on soft soil, multiple sets of soil-piercing heads 901 are fixedly connected to the outer side of the wheel assembly 301. These soil-piercing heads 901 have a conical protrusion structure that can embed into the surface soil, improving stability.

[0026] One end of the rotating rod 201 passes through the material distribution trough 107 and is fixedly connected to a first gear 951. A second gear 952 is fixedly connected to the outer side of the wheel rod 302. The first gear 951 and the second gear 952 are meshed together. When the device moves with the tractor, the wheel assembly 301 rotates under the action of soil friction, which in turn drives the wheel rod 302 to rotate synchronously. The wheel rod 302 drives the second gear 952 fixed on the outer side to rotate. Since the first gear 951 and the second gear 952 are meshed together, the second gear 952 drives the rotating rod 201 to rotate through the first gear 951, realizing the linkage between the material dispensing component and the moving action. No additional power source is required, simplifying the structure and reducing energy consumption.

[0027] During operation, the entire device is securely fixed to the rear of the tractor through the device mounting hole 106 on the device connector 103, ensuring that the connection is not loose and preventing it from falling off during operation. According to the needs of the crop to be cultivated, the height of the plowing grab 109 is adjusted through the lifting component, and then sufficient material to be applied is loaded into the feeding trough 108. The material falls naturally into the distributing trough 107 and is guided by the inclined surface of the pouring block 701 on the inner side of the distributing trough 107, and is concentrated in the rotating area of ​​the semi-circular distributing spoon 202, in preparation for the distributing operation. The tractor is started, and the entire device moves along the cultivated area. The wheel assemblies 301 at both ends of the distribution trough 107 rotate as the device moves. The soil-piercing heads 901 on the outside of the wheel assemblies 301 embed into the surface soil, increasing the friction with the soil and preventing the wheels from slipping. At the same time, the two wheel rods 302 provide stable support for the distribution trough 107, ensuring that the device does not tilt or shake during movement. When the wheel assemblies 301 rotate, they drive the wheel rods 302 to rotate synchronously. The second gear 952 on the outside of the wheel rods 302 rotates together with the wheel rods 302. Since the first gear 951 and the second gear 952 mesh, the second gear 952 drives the first gear 951 to rotate, which in turn drives the rotating rod 201 to rotate in the distribution trough 107. The rotating rod 201 synchronously drives all the semi-circular dispensing scoops 202 to rotate. During this process, the device vibrates slightly as the tractor plows the land. With the guidance of the material dispensing block 701, the semi-circular dispensing spoon 202 evenly scrapes the material in the dispensing trough 107 into each dispensing hole 111, achieving precise material distribution. At the same time, the soil-breaking block 801 at the end of the plowing grab 109 cuts into the soil first, breaking the soil to form a regular soil trough. The material in the dispensing hole 111 flows into the inside of the plowing grab 109 through the hollow limiting frame 110, and then is directly discharged into the broken soil trough through the discharge hole 112 at the lower end of the plowing grab 109, completing the fertilization operation. As the tractor continues to move, the device cycles through plowing, dispensing, and fertilizing, achieving integrated operation. Example

[0028] like Figures 5-9 As shown, the lifting assembly includes a mounting frame 401, a fixed connecting frame 402, a lifting plate 403, a first row of serrated grooves 404, a snap-fit ​​plate 405, and a second row of serrated grooves 406. The end of the material distribution trough 107 near the device connector 103 is symmetrically and fixedly connected to the mounting frame 401. The mounting frame 401 is welded from steel plate and has sufficient structural strength to bear the lifting load. The upper ends of multiple sets of plowing grippers 109 are jointly and fixedly connected to the fixed connecting frame 402. The fixed connecting frame 402 enables synchronous linkage of multiple sets of plowing grippers 109, ensuring that all plowing grippers 109 have the same depth during lifting. The upper end of the fixed connecting frame 402 is vertically and fixedly connected to the lifting plate 403. The lifting plate 403 and the fixed connecting frame 402 are connected by full welding to improve connection stability. The end of the lifting plate 403 is provided with a first equal row of sawtooth grooves 404. The sawtooths adopt an isosceles triangular structure, and the meshing force is uniform. A snap-fit ​​plate 405 is provided on one symmetrical side of the lifting plate 403. The snap-fit ​​plate 405 is provided with a second equal row of sawtooth grooves 406 that are adapted to the size of the first equal row of sawtooth grooves 404 at one end near the lifting plate 403. The first equal row of sawtooth grooves 404 and the second equal row of sawtooth grooves 406 mesh with each other. The height positioning of the lifting plate 403 is achieved through sawtooth meshing. The meshing surfaces are tightly fitted, which can effectively resist vibration and impact during operation and prevent the lifting plate 403 from loosening and shifting.

[0029] The two ends of the snap-fit ​​plate 405 are symmetrically fixedly connected with mounting blocks 501. The mounting blocks 501 and the snap-fit ​​plate 405 are integrally formed, resulting in higher structural strength. A first threaded hole 502 is provided on the inner side of the mounting block 501, and a second threaded hole 503 is provided on the inner side of the mounting bracket 401 corresponding to the position of the first threaded hole 502. The mounting block 501 is located inside the mounting bracket 401, and the two are interlocked. The interlocking structure provides horizontal guidance and limitation for the snap-fit ​​plate 405, ensuring that the second row of serrated grooves 406 can be accurately aligned and engaged with the first row of serrated grooves 404. In use, bolts are passed through the first threaded hole 502 and the second threaded hole 503 to fasten the mounting block 501 and the mounting bracket 401, thereby locking the position of the snap-fit ​​plate 405 and fixing the lifting plate 403. Loosening the bolts allows the snap-fit ​​plate 405 to be moved horizontally, releasing the serrated engagement restriction and facilitating the adjustment of the height of the lifting plate 403.

[0030] The first serrated groove 404 has symmetrically fixedly connected limit blocks 601 at both ends. A limit groove 602 is formed on the inner side of the mounting bracket 401. The two limit blocks 601 are located inside the limit groove 602 and are slidably connected to it. The sliding engagement between the limit blocks 601 and the limit groove 602 provides precise guidance for the vertical movement of the lifting plate 403, ensuring smooth vertical movement of the lifting plate 403 and preventing tilting during lifting.

[0031] During operation, to adapt to the plowing depth requirements of different crops, the plowing depth is first preset and adjusted. During adjustment, first use a wrench to loosen the fastening bolts inside the first threaded hole 502 and the second threaded hole 503. After the bolts are loosened, the snap-fit ​​plate 405 loses its fixed constraint and can move horizontally along the interlocking structure of the mounting frame 401; pull the snap-fit ​​plate 405 away from the lifting plate 403 so that the second row of serrated grooves 406 and the first row of serrated grooves 404 are completely disengaged. At this time, the lifting plate 403 is released from its positioning restriction and can move up and down with the fixed connecting frame 402. According to the preset plowing depth, manually push the fixed connecting frame 402 to drive the lifting plate 403 to move up and down synchronously. The limiting blocks 601 at both ends of the lifting plate 403 slide vertically along the limiting grooves 602 of the mounting frame 401 to guide the lifting plate 403 and ensure that all plowing grabs 109 move up and down synchronously in the vertical direction, avoiding the situation where the depth of a single plowing grab 109 deviates. When the soil-breaking block 801 of the plowing grab 109 reaches the preset height, stop moving the fixed connecting frame 402 and push the locking plate 405 towards the lifting plate 403 so that the second row of serrated grooves 406 and the first row of serrated grooves 404 are precisely engaged. After engagement, tighten the bolts again to fasten the mounting block 501 to the mounting frame 401, lock the position of the locking plate 405, and thus fix the height of the lifting plate 403 and the plowing grab 109, completing the depth adjustment. During operation, the lifting assembly remains locked. The meshing structure of the first row of serrated grooves 404 and the second row of serrated grooves 406 can resist the vibration and impact of plowing and the reaction force of the soil, preventing the lifting plate 403 from loosening and ensuring that the plowing depth remains consistent. The interlocking structure of the mounting block 501 and the mounting frame 401, and the sliding fit structure of the limiting block 601 and the limiting groove 602 further enhance the impact resistance of the assembly and avoid problems such as component displacement and jamming during operation.
