Description

Technical Field

[0001] This utility model relates to the technical field of green manure seed coating equipment, and in particular to a green manure seed coating device. Background Technology

[0002] Against the backdrop of sustainable agricultural development and the promotion of green planting technologies, green manure seed coating, as a key step in improving sowing quality, optimizing soil fertility, and reducing chemical inputs, is facing an increasingly urgent need for technological innovation. However, existing coating equipment suffers from significant shortcomings in terms of coating uniformity, operational adaptability, and equipment maintenance efficiency, becoming a core pain point hindering the modernization of agriculture.

[0003] However, traditional coating operations mostly rely on manual mixing or simple roller machinery, which has the following drawbacks:

[0004] The mixing mode is limited: the fixed speed of the drum cannot adapt to different seed shapes (such as particle size and surface roughness) and coating material characteristics (such as viscosity and flowability), resulting in uneven coating layer thickness. This can easily lead to problems such as excessively thick coating layers affecting seed respiration, or excessively thin coating layers failing to effectively protect the embryo.

[0005] Lack of dynamic control: There is a lack of real-time monitoring and feedback mechanism for the adhesion state of materials during the coating process. When the ambient temperature and humidity change (such as the coating material clumping in a high humidity environment), the stirring parameters cannot be automatically adjusted, which further aggravates the coating defect rate.

[0006] According to experimental data from the Agricultural Mechanization Research Institute, the first-time coating qualification rate of traditional coating equipment is only 65%-75%, resulting in about 20%-30% of seeds needing to be reworked or discarded directly, significantly increasing production costs.

[0007] Moreover, the contradiction between the highly fixed nature of the equipment and the diversity of application scenarios is prominent. To address this, we have provided a green manure seed coating device. Utility Model Content

[0008] To address the aforementioned problems, this invention proposes a green manure seed coating device, which more precisely solves the problems mentioned in the background section.

[0009] This utility model is achieved through the following technical solution:

[0010] The utility model proposes a green manure seed coating device, including an installation frame, a hopper fixedly welded to the upper surface of the installation frame, a shaft rod rotatably connected to the installation frame via a bearing, and a coating roller fixedly installed around the shaft rod and designed directly below the discharge port of the hopper for coating green manure seeds.

[0011] The mounting frame is rotatably connected to a filter-type feeding plate via a rotating shaft and is designed to be directly below the hopper's feeding port. A drive structure is connected between the mounting frame and the rotating shaft.

[0012] The drive structure includes an L-shaped frame one fixedly welded to the mounting frame and a gear disk one fixedly installed on the periphery of the shaft rod end. The L-shaped frame one is fixedly mounted with a locking gear by a plug rod. The surface of the locking gear is fixedly mounted with a gear disk two, and the surface of the gear disk two is fixedly mounted with a crank handle.

[0013] A linkage mechanism is connected between the filter-type feeding plate and the locking gear to achieve the shaking of the filter-type feeding plate.

[0014] Furthermore, the linkage mechanism includes an L-shaped frame two welded to the mounting frame and a linkage rod rotatably connected to the side of the filter-type feed plate via a rotating shaft. The L-shaped frame two is rotatably connected to a rotating rod via a bearing. One end of the rotating rod is fixedly connected to a fixed disk. A sliding groove is provided on the surface of the fixed disk. One end of the linkage rod is rotatably connected to a movable connecting piece via a rotating shaft. The movable connecting piece is movably connected to the inner wall of the sliding groove. A gear disk three is fixedly welded to the periphery of the rotating rod.

[0015] Furthermore, the side of the device is connected to a height adjustment component for adjusting the overall usage height of the device;

[0016] The height adjustment assembly includes a hollow support rod fixedly installed on the side of the mounting frame, and an insertable support rod is inserted into the inner wall of the hollow support rod.

[0017] Furthermore, the height adjustment assembly also includes threaded holes on the sides of the hollow support rod and the plug-in support rod, with a torsion screw threaded into the inner wall of the threaded hole to limit the relative movement of the hollow support rod and the plug-in support rod.

[0018] Furthermore, the gear disk three is meshed with the locking gear, which drives the rotating rod to rotate while the locking gear rotates.

[0019] Furthermore, the second gear disk is meshed with the first gear disk, and is used to drive the shaft rod and the wrapping roller to rotate while the second gear disk rotates.

[0020] The beneficial effects of this utility model are:

[0021] This invention significantly improves the uniformity of the coating process and the quality of seed treatment through mechanical transmission and linkage design. The operator cranks the handle, which, through the meshing of gear disc two and gear disc one, drives the shaft to rotate the coating roller stably. The surface of the coating roller makes full contact and friction with the falling seeds and coating material, ensuring that the coating material adheres evenly to the seed surface, avoiding problems such as uneven coating and missed coatings common in traditional manual coating or simple devices.

[0022] This invention significantly optimizes applicability and ease of operation through a height adjustment component and modular structure design. The height adjustment component uses a hollow support rod and a plug-in support rod for plugging together, combined with a locking mechanism of threaded holes and torque screws, allowing operators to quickly and accurately adjust the height of the device according to the actual usage scenario.

[0029] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model. Example

[0030] like Figures 1-5As shown in the figure, an embodiment of this utility model discloses a green manure seed coating device, including a mounting frame 1. A hopper 2 is fixedly mounted on the upper surface of the mounting frame 1 by welding. The hopper 2 is used to hold the green manure seeds to be coated and a mixture of coating materials such as binders, fertilizers, and pesticides. The two sides of the mounting frame 1 are rotatably connected to a shaft rod 3 via a bearing structure. The shaft rod 3 horizontally spans the mounting frame 1, and a coating roller 4 is fixedly mounted on its periphery. The coating roller 4 is located directly below the discharge port of the hopper 2. Its surface can be designed to have a certain roughness or texture so that it can fully contact and rub against the seeds and coating materials during rotation to achieve uniform coating. The mounting frame 1 is rotatably connected to a filter-type discharge plate 5 near the discharge port of the hopper 2 via a rotating shaft. The surface of the filter-type discharge plate 5 is distributed with several small holes to screen out coating material powder or clumps that have not fully adhered to the seeds, allowing only coated seeds to fall smoothly.

[0031] In the drive structure, an L-shaped frame 6 is fixedly welded to the side of the mounting frame 1. A through hole is opened at the end of the vertical section of the L-shaped frame 6, allowing the locking gear 8 to be detachably and fixedly installed via a pin or similar component. The locking gear 8 is simultaneously connected to the horizontal section of the L-shaped frame 6 via a bearing, ensuring stable rotation around its own axis. A gear disk 10 is fixedly mounted to the end face of the locking gear 8 via bolts. A crank handle 11 is welded to the end face of the gear disk 10 for manual rotation by the operator. A gear disk 9 is fixedly mounted to the outer periphery of the shaft rotating rod 3 via a key connection. The gear disk 9 and gear disk 10 are compatible in specifications and mesh with each other. The operator manually cranks the crank handle 11, causing the gear disk 10 and locking gear 8 to rotate synchronously. This meshing action drives the gear disk 9 and shaft rotating rod 3 to rotate, causing the coating roller 4 to rotate and complete the coating operation. Simultaneously, the rotation of the locking gear 8 triggers a subsequent linkage mechanism, driving the filter-type feeding plate 5 to vibrate.

[0032] Furthermore, an L-shaped frame 7 is welded to the mounting frame 1 near the side of the filter-type feed plate 5. The vertical end of the L-shaped frame 7 is rotatably connected to a rotating rod 13 via a bearing structure. The rotating rod 13 is horizontally arranged and parallel to the side of the filter-type feed plate 5. One end of the rotating rod 13 is fixedly mounted to a fixed plate 14 via a key. A sliding groove 15 is formed on the surface of the fixed plate 14. The sliding groove 15 is an elongated hole, and its length direction is consistent with the radial direction of the fixed plate 14. The side of the filter-type feed plate 5 is rotatably connected to a linkage rod 12 via a rotating shaft. The end of the linkage rod 12 away from the filter-type feed plate 5 is rotatably connected to a movable connector 16 via a rotating shaft. The movable connector 16 is a cylindrical slider, the diameter of which is adapted to the width of the sliding groove 15. The movable connector 16 can slide along its length direction and rotate around its own axis within the sliding groove 15. A gear disk 17 is fixedly mounted to the periphery of the rotating rod 13 via a key. The gear disk 17 meshes with the subsequent locking gear 8.

[0033] When the gear 8 rotates, it drives the gear disk 17 and the rotating rod 13 to rotate synchronously through meshing, which in turn causes the fixed disk 14 to rotate. The movable connecting piece 16 slides in the sliding groove 15 and drives the linkage rod 12 to swing, which in turn drives the filter feeding plate 5 to swing up and down around its axis, realizing the shaking screening function and effectively separating the unadhesive coating material.

[0034] Furthermore, a hollow support rod 18 is welded to the side of the mounting frame 1. The hollow support rod 18 is a hollow square or round steel tube, and its inner wall dimension is slightly larger than the outer wall dimension of the plug-in support rod 19. The plug-in support rod 19 is a solid square or round steel rod, one end of which is inserted into the hollow support rod 18, and the up and down sliding adjustment is achieved through plug-in cooperation.

[0035] The operator can manually slide and connect the support rod 19 up and down according to the actual use scenario, such as the height of the operating table and the height of the seed collection container, to adjust the height of the installation frame 1 and the entire coating device, so as to ensure that the discharge port of the hopper 2 is compatible with the height of the seed receiving device such as the collection box and the conveyor belt, thereby improving the convenience and efficiency of operation.

[0036] Furthermore, several threaded holes 20 are evenly formed along the length of the hollow support rod 18 and the plug-in support rod 19. The diameter of the threaded holes 20 is adapted to the thread diameter of the torque screw 21. After the plug-in support rod 19 is adjusted to a suitable height, the torque screw 21 is screwed into the threaded holes 20 at corresponding positions on the hollow support rod 18 and the plug-in support rod 19 until the end of the torque screw 21 presses tightly against the surface of the plug-in support rod 19, thus restricting the relative movement of the two through friction.

[0037] The fixing function of the torsion screw 21 ensures that the plug-in support rod 19 will not slip unexpectedly due to device vibration or external force after being adjusted to the appropriate height, thus ensuring the stability and safety of the device, and at the same time, it makes it easy for operators to quickly and accurately lock the height of the device.

[0038] Furthermore, gear disk 317 is adapted to and meshes with the locking gear 8. The number of teeth, module, and other parameters of gear disk 317 are designed according to the actual transmission ratio requirements to ensure that the locking gear 8 can drive gear disk 317 to rotate at a suitable speed when rotating.

[0039] When the operator cranks the crank handle 11 to drive the locking gear 8 to rotate, the locking gear 8 drives the gear disc 17 to rotate synchronously through meshing, which in turn causes the rotating rod 13 to rotate, ultimately driving the filter-type feed plate 5 to vibrate. This meshing transmission structure is simple and reliable, and can effectively transmit power to realize the vibration screening function of the filter-type feed plate 5.

[0040] Furthermore, gear disk 2 10 is adapted to and meshes with gear disk 1 9. The number of teeth, module and other parameters of gear disk 2 10 are designed according to the speed requirements of the wrapping roller 4 to ensure that the shaft rod 3 and the wrapping roller 4 can be driven to rotate at a suitable speed when the rocker handle 11 is turned.

[0041] The operator manually cranks the crank handle 11, which rotates the gear disk 10. The gear disk 10, through meshing, drives the gear disk 9 and the shaft rod 3 to rotate, thereby causing the coating roller 4 to rotate. This meshing transmission structure can precisely control the rotation speed of the coating roller 4, ensuring that the coating material is fully mixed and evenly coated with the green manure seeds, thus improving the coating quality and efficiency.
