Abstract

This invention discloses an intelligent seeding device for deep tillage and stratified fertilization, belonging to the field of agricultural planting machinery. It includes a mounting plate with two feeding mechanisms on its lower surface; hydraulic mechanisms symmetrically mounted on its upper surface; two soil-covering mechanisms at the front and rear of the mounting plate; a linkage mechanism between the two opposite soil-covering mechanisms on the upper surface of the mounting plate; a drive mechanism between the two hydraulic mechanisms on the upper surface of the mounting plate; and a furrowing mechanism on the left side of the mounting plate.

Description

Technical Field

[0001] This invention relates to the field of agricultural planting machinery, and in particular to an intelligent seeding device for deep tillage and stratified fertilization. Background Technology

[0002] In agricultural sowing, fertilization is necessary to provide sufficient nutrients for crop production. In current technology, furrows are typically dug in the field using a furrowing shovel, and then fertilization and sowing are carried out in the furrows. To avoid seedling burn caused by direct contact between seeds and fertilizer, fertilization and sowing are usually carried out separately. That is, fertilizer is first applied in the furrows, then a layer of soil is applied, and then sowing is done. After sowing, a second layer of soil is applied. This planting method requires multiple processes such as furrowing, fertilization, first layer of soil application, sowing, and second layer of soil application, resulting in low sowing efficiency.

[0003] Existing seeding devices, especially for layered fertilization seeding, typically require a moving device to first open furrows, then apply fertilizer, and simultaneously cover the soil with soil. Afterward, the device is moved back to complete the seeding and secondary soil covering. This makes the layered soil covering and fertilization process complex, and each of the steps—fertilization, primary soil covering, seeding, and secondary soil covering—requires multiple driving devices. It is not possible to control fertilization, primary soil covering, seeding, and secondary soil covering simultaneously with the movement of the device. Therefore, we propose an intelligent seeding device for deep loosening and layered fertilization. Summary of the Invention

[0004] Purpose of the Invention: The purpose of this invention is to provide an intelligent seeding device for deep tillage and stratified fertilization, which simplifies the operation process of seeding and fertilization, reduces the repetitive steps of trenching, fertilization, covering soil, and seeding, and improves seeding efficiency. Another purpose of this invention is to provide an intelligent seeding device for deep tillage and stratified fertilization that can complete stratified fertilization and seeding without the need for a reciprocating moving device, and synchronously controls the actions of fertilization, primary covering soil, seeding, and secondary covering soil through a single drive device, thereby reducing the complexity of the device structure and the cost of use.

A receiving rod is fixedly connected to the upper surface of the gear two and located outside the shaft column two. The gear two meshes with the rack two.

[0015] Furthermore, the lower surface of the mounting plate is fixedly connected to multiple support legs, and the bottom of each support leg is rotatably mounted with rollers via a pivot. A traction fixing frame is symmetrically fixedly connected to the left side of the mounting plate.

[0016] Furthermore, storage cylinders are fixedly connected to both sides of the upper surface of the mounting plate.

[0017] Furthermore, the top of the material cylinder is integrally formed with a feed pipe, the top end of which is fixedly connected to the bottom of the storage cylinder, and the bottom of the material cylinder is integrally formed with a discharge pipe, and the outer side wall of the discharge tray is provided with a receiving port.

[0018] Furthermore, the rack and pinion are meshed with the gear; the top of the hydraulic tank and the top of the hydraulic box are fixedly connected to the upper and lower surfaces of the mounting plate, respectively; a spring is fixedly connected between the piston and the hydraulic tank; a one-way groove is provided on the upper surface of the actuating rod and on the outside of the shaft; a one-way block is fixedly connected to the outer side of the shaft on the outer side of the one-way groove; a stop plate is fixedly connected to the ends of the two actuating rods on the same side away from the piston; and a spring is fixedly connected between the one-way block and the one-way groove.

[0019] Furthermore, bulldozer blade 1 is fixedly connected to the opposite ends of the two L-shaped brackets located on the left side of the outer side of the mounting plate, and crossbar is fixedly connected to the opposite ends of the two L-shaped brackets located on the right side of the outer side of the mounting plate. Bulldozer blade 2 is fixedly connected to the opposite right sides of the two crossbars. The top of the guide seat is fixedly connected to the lower surface of the mounting plate, and spring 2 is fixedly connected to the opposite sides of the guide seat and the L-shaped brackets, located on the outside of the slide rod.

[0020] Furthermore, a one-way groove is formed on the upper surface of the receiving rod and on the outer side of the second shaft post. A one-way block is fixedly connected to the outer side of the second shaft post and on the inner side of the one-way groove. The bottom end of the second shaft post is fixedly connected to the upper surface of the mounting plate. The receiving rod and the actuating rod are on the same horizontal plane.

[0021] Furthermore, the drive mechanism includes a mounting bracket, a motor is fixedly connected to the inner side of the mounting bracket, and a cam is fixedly connected to the bottom end of the output shaft of the motor, the cam being located between the two abutments.

[0022] Furthermore, the trenching mechanism includes a screw, the bottom end of which is rotatably connected to the left side of the upper surface of the mounting plate via a rotating shaft. A lifting frame is threadedly connected to the outer wall of the screw, and a triangular trenching shovel is fixedly connected to the bottom end of the lifting frame. A guide sleeve is slidably connected to the outer side of the lifting frame, and the guide sleeve is fixedly connected to the opposite side of the mounting plate.

[0023] Beneficial effects: In response to the problem that existing technologies require multiple decentralized processes for sowing, such as trenching, fertilization, primary covering, sowing, and secondary covering, and often require reciprocating moving devices to complete layered fertilization and sowing, this device achieves continuous operation of "fertilization - primary covering - sowing - secondary covering" through the coordinated linkage of various mechanisms.

[0024] During the movement of the device, there is no need to turn back and forth. All key processes can be completed in the reasonable order required for agricultural production. This completely reduces the repetitive steps in the process, effectively shortens the time of a single sowing operation, and significantly improves the overall sowing efficiency. It is especially suitable for large-scale sowing operations in large areas of farmland.

[0025] Existing stratified fertilization and seeding devices often require multiple drive units to control fertilization, soil covering, and seeding separately, resulting in complex structures and high failure rates. This new device, however, relies on a unique mechanism design that allows for simultaneous control of the entire operation with a single drive unit: the drive unit first acts on the hydraulic mechanism corresponding to fertilization, triggering the feeding mechanism to complete fertilization; when the hydraulic mechanism resets, it drives the soil covering mechanism via a linkage mechanism to achieve the first soil covering; subsequently, the drive unit continues to operate, acting on the hydraulic mechanism corresponding to seeding, controlling the feeding mechanism to complete seeding; finally, the hydraulic mechanism resets again to drive the soil covering mechanism for the second soil covering. The entire process eliminates the need for multiple additional drive components, significantly simplifying the overall structure of the device, reducing the probability of mechanical failures, and facilitating subsequent maintenance and repair.

[0026] To address the agricultural production problem of seed burn caused by direct contact between seeds and fertilizers, this device achieves layered isolation between fertilizers and seeds through precise process design and mechanism coordination. The left-side soil covering mechanism corresponds to the trench after fertilization, pushing soil over the fertilizer to complete the first layer of soil covering, forming an isolation layer; the right-side soil covering mechanism corresponds to the trench after sowing, covering the seeds with soil again, so that the fertilizer is in the lower layer and the seeds are in the upper layer, with soil separating the two layers. This fundamentally avoids direct contact between seeds and fertilizers, ensuring normal seed germination and growth, and improving the emergence rate and early crop growth quality after sowing.

[0027] On the one hand, the single-drive design significantly reduces the procurement and manufacturing costs of core components compared to multi-drive designs, thereby lowering the overall production cost of the device. On the other hand, the simplified structure results in lower energy consumption during daily use, while also reducing the number of vulnerable parts, thus lowering the frequency and cost of later maintenance and component replacement. Furthermore, the operational logic of each mechanism is clear, and the bulldozer blades of the covering mechanism remain open when not in operation, facilitating device movement and trench alignment, reducing the difficulty of operation for personnel, and further enhancing the practicality and economy of the device in actual agricultural production.

[0039] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Example

[0041] like Figure 1 As shown, an intelligent seeding device for deep tillage and stratified fertilization is provided, including a mounting plate 1;

[0042] Multiple support legs 8 are fixedly connected to the lower surface of the mounting plate 1. Rollers 9 are rotatably mounted on the bottom of the support legs 8 via a pivot. Traction fixing frames 10 are symmetrically fixedly connected to the left side of the mounting plate 1.

[0043] Storage cylinders 11 are fixedly connected to both sides of the upper surface of the mounting plate 1;

[0044] In use, the mounting plate 1 is fixedly connected to an external traction device, such as a tractor, via the traction fixing frame 10. Fertilizer is pre-filled in the left storage cylinder 11, and seeds are pre-filled in the right storage cylinder 11. The rollers 9 at the bottom of the support legs 8 move with the traction device to achieve stable movement of the entire device, providing a mobile foundation for subsequent ditching, fertilization, sowing and soil covering processes.

[0045] like Figure 2 As shown, two feeding mechanisms 2 are provided on the lower surface of the mounting plate 1;

[0046] The feeding mechanism 2 includes a material cylinder 201. A feeding disc 202 is rotatably mounted on the inner side of the material cylinder 201 via a rotating shaft. A gear 203 is fixedly connected to the front end of the central shaft of the feeding disc 202 in front of the material cylinder 201.

[0047] The top of the material cylinder 201 is integrally formed with a feed pipe 204, the top of the feed pipe 204 is fixedly connected to the bottom of the storage cylinder 11, the bottom of the material cylinder 201 is integrally formed with a discharge pipe 205, and the outer side wall of the discharge tray 202 is provided with a receiving port 206.

[0048] In use, fertilizer in the left storage cylinder 11 enters the left material cylinder 201 through the feed pipe 204, and seeds in the right storage cylinder 11 enter the right material cylinder 201 through the feed pipe 204. When the feeding tray 202 rotates under the drive of gear 203, the receiving port 206 will periodically receive fertilizer or seeds falling from the feeding pipe 204. When the feeding tray 202 rotates to the position of the feeding pipe 205, the fertilizer or seeds are quantitatively delivered to the farmland ditch through the feeding pipe 205, realizing precise feeding control.

[0049] like Figure 3 , Figure 4 and Figure 10 As shown, hydraulic mechanisms 3 are symmetrically mounted on the upper surface of mounting plate 1;

[0050] The hydraulic mechanism 3 includes a hydraulic tank 301, a piston 302 that is slidably connected inside the hydraulic tank 301, two push rods 303 that are fixedly connected to the opposite sides of the two pistons 302, a shaft 304 that is fixedly connected to the top of the push rods 303, and a lever 305 that is rotatably mounted on the outer side of the shaft 304; hydraulic pipes 306 that are fixedly connected to the opposite sides of the two hydraulic tanks 301, a hydraulic box 307 that is fixedly connected to the bottom end of the hydraulic pipes 306, a piston 308 that is slidably connected inside the hydraulic box 307, and a rack 309 that is fixedly connected to the lower surface of the piston 308;

[0051] Rack 309 meshes with gear 203. The top of hydraulic tank 301 and the top of hydraulic box 307 are fixedly connected to the upper and lower surfaces of mounting plate 1, respectively. Piston 302 and hydraulic tank 301 are fixedly connected together by spring 310. One-way groove 311 is provided on the upper surface of actuating rod 305 and outside the shaft column 304. One-way block 312 is fixedly connected to the outer side of the shaft column 304 inside the one-way groove 311. The ends of the two actuating rods 305 on the same side away from piston 302 are fixedly connected together by abutment plate 313. One-way block 312 and one-way groove 311 are fixedly connected together by spring 314.

[0052] When in use, when the abutment 313 is squeezed by the drive mechanism 6, it will drive the two actuating rods 305 on the same side to move towards the piston 302 along with the push rod 303. When the actuating rod 305 contacts the corresponding actuated rod 503 on the linkage mechanism 5, the actuating rod 305 will be blocked. At the same time, since the actuating rod 305 is not limited by the one-way groove 311 and one-way block 312, the actuating rod 305 will rotate and will not drive the linkage mechanism 5 to move from one side to the other side.

[0053] At this time, as the push rod 303 moves toward the hydraulic tank 301, the piston 302 will compress the spring 310 and slide inside the hydraulic tank 301, pressing the hydraulic oil in the hydraulic tank 301 into the hydraulic box 307 through the hydraulic pipe 306, pushing the piston 308 to slide downward, driving the rack 309 to move downward, and the rack 309 meshes with the drive gear 203 to rotate, realizing the feeding action of the feeding mechanism 2;

[0054] When the drive mechanism 6 releases the pressure on the support plate 313, the spring 310 resets and pushes the piston 302 back, the hydraulic oil flows back, and the feeding mechanism 2 resets to receive the next seed and fertilizer for sowing.

[0055] At this time, piston 302 moves and resets, and push rod 303 and actuating rod 305 move and reset together to the side away from hydraulic tank 301. At this time, as the actuating rod 305 moves and contacts the linkage mechanism 5, it will drive the linkage mechanism 5, and then drive the soil covering mechanism 4 through the linkage mechanism 5 to realize the soil covering work.

[0056] During this process, when the drive mechanism 6 is driven, it will first control the hydraulic mechanism 3 on the left side of the upper surface of the mounting plate 1 to drive, and then control the feeding mechanism 2 to feed fertilizer. As the drive mechanism 6 disengages from the control of the left hydraulic mechanism 3, during the reset process of the left hydraulic mechanism 3, it will drive the linkage mechanism 5 through the toggle lever 305 to control the left covering mechanism 4 to cover the soil, thus completing the soil covering work above the fertilizer, that is, the process from fertilization to soil covering.

[0057] As the drive mechanism 6 continues to operate and drives the hydraulic mechanism 3 on the right, the hydraulic mechanism 3 on the right will be linked with the feeding mechanism 2 containing seeds, thereby controlling the feeding mechanism 2 to feed and sow seeds.

[0058] Then, when the drive mechanism 6 disengages from the hydraulic mechanism 3 on the right, during the reset process of the hydraulic mechanism 3 at that location, the adjacent linkage mechanism 5 will be activated by the lever 305 at that location to drive the corresponding soil covering mechanism 4, thereby realizing the soil covering work after the seed sowing is completed, that is, the process from sowing to secondary soil covering.

[0059] like Figure 6 and Figure 7 As shown, two soil covering mechanisms 4 are provided at the front and rear of the mounting plate 1;

[0060] The soil covering mechanism 4 includes a guide seat 401, a slide rod 402 is slidably connected to the inner side of the guide seat 401, and L-shaped brackets 403 are fixedly connected to the opposite ends of the two slide rods 402 that are opposite to each other. A rack 404 is fixed to the top of the L-shaped bracket 403.

[0061] Two L-shaped brackets 403 located on the left side of the outer side of the mounting plate 1 are fixedly connected to opposite ends of bulldozer blade 405. Two L-shaped brackets 403 located on the right side of the outer side of the mounting plate 1 are fixedly connected to opposite ends of crossbar 406. Two bulldozer blades 407 are fixedly connected to opposite right sides of the two crossbars 406. The top of the guide seat 401 is fixedly connected to the lower surface of the mounting plate 1. Spring 408 is fixedly connected to opposite sides of the guide seat 401 and L-shaped brackets 403, and to the outside of the slide bar 402.

[0062] In use, the first bulldozer plate 405 of the left-side soil covering mechanism 4 corresponds to the trench position after fertilization, and the second bulldozer plate 407 of the right-side soil covering mechanism 4 corresponds to the trench position after sowing; and the height of the first bulldozer plate 405 is higher than the height of the second bulldozer plate 407, which makes it easier to push the soil pushed to both sides of the trench by the triangular trenching shovel 703 of the trenching mechanism 7 into the trench from both sides, so as to achieve secondary soil covering: the first bulldozer plate 405 pushes the upper soil on both sides of the trench to cover fertilizer, and the second bulldozer plate 407 pushes the lower soil on both sides of the trench to cover seeds;

[0063] When rack 2 404 is driven by gear 2 502 of linkage mechanism 5, it will drive L-shaped bracket 403 to slide along slide rod 402 in guide seat 401, compressing or stretching spring 2 408: the left bulldozer plate 1 405 is relatively close, pushing the soil on both sides of the trench into the fertilization area to complete the first covering soil, and the right bulldozer plate 2 407 is relatively close, pushing the soil into the sowing area to complete the second covering soil.

[0064] The elastic reset function of spring 408 can keep bulldozer blade 405 and bulldozer blade 407 in the open state when not in operation, which facilitates the movement of the device and the alignment of the trench. At the same time, when controlling the two racks 404 to move and reset in opposite directions, the linkage mechanism 5 is reset by driving gear 502.

[0065] The elastic force of spring 408 is much smaller than that of spring 310. It is only used to assist the resetting of bulldozer plate 405, bulldozer plate 407 and gear 502. It will not hinder spring 310 from pushing piston 302 to move and reset.

[0066] like Figure 5 As shown, the upper surface of the mounting plate 1 is provided with a linkage mechanism 5 between the two opposite soil covering mechanisms 4.

[0067] The linkage mechanism 5 includes a shaft column 501, a gear 502 is rotatably connected to the outer wall of the shaft column 501 via a rotating shaft, and a lever 503 is fixedly connected to the upper surface of the gear 502 and located outside the shaft column 501. The gear 502 meshes with the rack 404.

[0068] A one-way groove 504 is provided on the upper surface of the lever 503 and on the outside of the shaft 501. A one-way block 505 is fixedly connected to the outside of the shaft 501 and on the inside of the one-way groove 504. The bottom end of the shaft 501 is fixedly connected to the upper surface of the mounting plate 1. The lever 503 and the actuating lever 305 are on the same horizontal plane.

[0069] When the drive mechanism 6 is driven, the push rod 303 moves toward the hydraulic tank 301 by squeezing the abutment plate 313. At this time, the actuating rod 305 on the hydraulic mechanism 3 contacts the actuating rod 503 on the linkage mechanism 5. The actuating rod 503 is restricted by the one-way groove 504 and the one-way block 505 and cannot rotate. At the same time, since the actuating rod 305 is not restricted by the one-way groove 311 and the one-way block 312, it can rotate. Therefore, it will not drive the gear 502 to rotate, and thus will not drive the subsequent soil covering mechanism 4 to operate through the gear 502.

[0070] When the hydraulic mechanism 3 is reset, the actuating rod 305 moves away from the hydraulic tank 301. During the reset process, the actuating rod 305 is limited by the one-way groove 311 and the one-way block 312 and cannot rotate. When the actuating rod 305 contacts the actuated rod 503 in the linkage mechanism 5, the actuated rod 503 is not limited by the one-way groove 504 and the one-way block 505 and can rotate, thereby driving the gear 502 to rotate together, and then driving the rack 404 of the soil covering mechanism 4 to move, so as to realize the soil covering action.

[0071] Through the one-way transmission design of the linkage mechanism 5, the driving mechanism 6 will first control the fertilizer feeding mechanism 2 to feed the fertilizer during the driving process. When the feeding is completed and the hydraulic mechanism 3 is reset, the toggle lever 305 will drive the soil covering mechanism 4 to cover the soil, thus completing the first soil covering after fertilization.

[0072] As the drive mechanism 6 continues to drive, after the first layer of soil covering is completed, the drive mechanism 6 controls the seed feeding mechanism 2 to feed the seeds through the hydraulic mechanism 3 on the right, so that the seeds fall on top of the first layer of soil covering. When the hydraulic mechanism 3 is reset, the corresponding lever 305 drives the soil covering mechanism 4 on the right to cover the seeds, pushing the soil to cover the seeds and completing the second layer of soil covering, thus realizing the continuous process of "fertilization - first layer of soil covering - sowing - second layer of soil covering".

[0073] like Figure 8 As shown, a drive mechanism 6 is provided on the upper surface of the mounting plate 1 between the two hydraulic mechanisms 3;

[0074] The drive mechanism 6 includes a mounting bracket 601, a motor 602 is fixedly connected to the inner side of the mounting bracket 601, and a cam 603 is fixedly connected to the bottom end of the output shaft of the motor 602. The cam 603 is located between two abutment plates 313.

[0075] When in use, start the motor 602. The output shaft of the motor 602 drives the cam 603 to rotate at a constant speed. The protruding end of the cam 603 periodically and alternately presses the abutment plates 313 on both sides, providing a continuous driving force for the hydraulic mechanism 3. The rotation rhythm of the cam 603 controls the operation frequency of the feeding mechanism 2 and the covering mechanism 4, ensuring that the fertilization, primary covering, sowing, and secondary covering processes match the movement speed of the device, and achieving synchronous operation.

[0076] like Figure 9 As shown, a trenching mechanism 7 is provided on the left side of the mounting plate 1;

[0077] The trenching mechanism 7 includes a screw 701. The bottom end of the screw 701 is rotatably connected to the left side of the upper surface of the mounting plate 1 via a rotating shaft. The outer side wall of the screw 701 is threadedly connected to a lifting frame 702. The bottom end of the lifting frame 702 is fixedly connected to a triangular trenching shovel 703. The outer side of the lifting frame 702 is slidably connected to a guide sleeve 704. The guide sleeve 704 is fixedly connected to the opposite side of the mounting plate 1.

[0078] In use, the screw 701 is rotated according to the required trench depth for crop planting. The screw 701 and the lifting frame 702 are threaded together, causing the lifting frame 702 to slide up and down along the guide sleeve 704, thereby adjusting the soil penetration depth of the triangular trenching shovel 703. The guide sleeve 704 restricts the rotation of the lifting frame 702, ensuring that the triangular trenching shovel 703 rises and falls vertically and that the trenching depth is uniform. When the device moves, the triangular trenching shovel 703 opens continuous trenches in the farmland, providing an operating channel for subsequent fertilization and sowing, and pushing the soil pushed out during trenching to both sides of the trench, facilitating the subsequent covering soil mechanism 4.

[0079] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
