Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed dressing device technology, and in particular to a seed dressing device for wheat planting. Background Technology
[0002] Wheat seeds need to be treated with seed dressing primarily to prevent and control pests and diseases, improve germination and seedling survival rates, and thus ensure normal growth and yield. Seed dressing involves mixing seeds with an agent containing fungicides, insecticides, or micronutrients, ensuring the agent adheres evenly to the seed surface and forms a protective film. This effectively inhibits damage from pathogens and pests after sowing. Seed dressing can effectively prevent and control various diseases, such as sheath blight, take-all, root rot, loose smut, and flat smut. These diseases are usually transmitted through the soil or seeds. If not treated before sowing, pathogens will infect wheat seeds, leading to poor germination, yellowing leaves, or even seedling death.
[0003] In existing technologies, most seed dressing equipment adopts a fixed mixing structure, and the mixing blades can only rotate in a fixed area in one direction. This results in a limited contact range between wheat and the pesticide, which easily leads to local pesticide accumulation and some seeds not being coated with pesticide. The uniformity of seed dressing is poor, which directly affects the germination rate and disease resistance of subsequent seeds. Therefore, we propose a wheat planting seed dressing device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wheat planting and seed mixing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wheat seed treatment device includes a seed treatment frame. A U-shaped base is fixedly connected to the bottom of the seed treatment frame. Two rectangular inclined grooves are formed on the outer wall of the U-shaped base. A trapezoidal guide frame is fixedly connected to the inner wall of the two rectangular inclined grooves. A first hydraulic cylinder is fixedly connected inside the U-shaped base. A long strip blocking plate is fixedly connected to the top of the first hydraulic cylinder. A discharge trough is formed at the bottom of the seed treatment frame, and the inner wall of the discharge trough presses against the outer wall of the long strip blocking plate. Two U-shaped frames are fixedly connected inside the seed treatment frame. Long racks are fixedly connected inside each U-shaped frame. Spur gears are meshed with the outer walls of each long rack. A long shaft is fixedly connected between the two spur gears. A rectangular frame is fitted onto the outer wall of the long shaft. Two through holes are formed on the outer wall of the rectangular frame. Guide rods are slidably connected to the inner walls of each through hole. Both ends of the guide rods are fixedly connected to the inner wall of the seed treatment frame. A second hydraulic cylinder is fixedly connected to the outer wall of the seed treatment frame. The output end of the second hydraulic cylinder is fixedly connected to the outer wall of the rectangular frame. A seed treatment assembly is provided inside the seed treatment frame.

By setting the seed mixing component, the multiple stirring blades can realize the movement and stirring process, and the stirring blades adopt an inclined structure.
[0008] Preferably, the bottom of the trapezoidal guide frame is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the first oil cylinder.
[0009] Preferably, two ball bearings are fixedly sleeved at both ends of the long shaft, and long grooves are opened on the outer walls of the two U-shaped frames.

[0010] Preferably, the outer wall of the seed mixing frame has a through hole, and the inner wall of the through hole is slidably connected to the outer wall of the output end of the second oil cylinder. By setting the second oil cylinder to drive the long strip blocking plate to move downward, the material is discharged.
[0011] Preferably, tapered roller bearings are fixedly fitted on the outer walls of both the drive shaft and the long shaft. The outer ring of the tapered roller bearings is fixedly connected to the inner wall of the rectangular frame. The tapered roller bearings assist the drive shaft and the long shaft in stable movement and rotation.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] This solution uses a second hydraulic cylinder to move a rectangular frame, causing the mixing blades to rotate while moving. This combined action allows the wheat and the pesticide to come into full contact, breaking the limitations of the existing fixed mixing structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Depend on Figures 1-4 As shown, a wheat planting seed dressing device is disclosed, including a seed dressing frame 1. A U-shaped base 2 is fixedly connected to the bottom of the seed dressing frame 1. Two rectangular inclined grooves are opened on the outer wall of the U-shaped base 2. The same trapezoidal guide frame 3 is fixedly connected to the inner wall of the two rectangular inclined grooves. The U-shaped base 2 not only provides stable support for the seed dressing frame 1, but also enables the trapezoidal guide frame 3 to stably receive the material discharged from the seed dressing frame 1, thereby enhancing the overall structural stability of the device.
[0022] The U-shaped base 2 is internally fixedly connected to the first oil cylinder 5. The bottom of the trapezoidal guide frame 3 is provided with a sliding hole. The inner wall of the sliding hole is slidably connected to the outer wall of the output end of the first oil cylinder 5. The top of the first oil cylinder 5 is fixedly connected to a long strip blocking plate 4. The bottom of the seed mixing frame 1 is provided with a discharge trough. The inner wall of the discharge trough is pressed against the outer wall of the long strip blocking plate 4.
[0023] The seed mixing frame 1 has two fixedly connected U-shaped frames 6 inside. Both U-shaped frames 6 have long racks 7 fixedly connected inside. Both long racks 7 have spur gears 8 meshing with each other on their outer walls. When the spur gears 8 move linearly on the top of the long racks 7, they can cause the spur gears 8 to rotate, thus converting linear motion into rotational motion, providing a power source for the rotation of the subsequent stirring blades 16.
[0024] A long shaft 9 is fixedly connected between the two spur gears 8. Two ball bearings are fixedly sleeved at both ends of the long shaft 9. Long grooves are opened on the outer walls of the two U-shaped frames 6. The inner walls of the two long grooves are slidably connected to the outer rings of the two ball bearings respectively. The ball bearings reduce the friction when the long shaft 9 moves.
[0025] A rectangular frame 10 is fitted on the outer wall of the long axis 9. Two through holes are opened on the outer wall of the rectangular frame 10. Guide rods 11 are slidably connected to the inner walls of the two through holes. Both ends of the two guide rods 11 are fixedly connected to the inner wall of the seed mixing frame 1. The guide rods 11 play an auxiliary guiding role in the linear movement of the rectangular frame 10, ensuring that the rectangular frame 10 will not deviate during the movement.
[0026] The stability and accuracy of the movement of the rectangular frame 10 are ensured. The outer wall of the seed mixing frame 1 is fixedly connected to the second oil cylinder 12. The outer wall of the seed mixing frame 1 has a through hole. The inner wall of the through hole is slidably connected to the outer wall of the output end of the second oil cylinder 12. The output end of the second oil cylinder 12 is fixedly connected to the outer wall of the rectangular frame 10.
[0027] The seed mixing frame 1 is equipped with a seed mixing assembly, which includes a drive shaft 13. The drive shaft 13 rotates under the drive of two bevel gears 14 and moves linearly with the rectangular frame 10, transmitting power to multiple stirring blades 16. A circular hole is provided at the bottom of the rectangular frame 10, and the inner wall of the circular hole is rotatably connected to the outer wall of the drive shaft 13. Tapered roller bearings are fixedly fitted on the outer walls of both the drive shaft 13 and the long shaft 9. The outer ring of the tapered roller bearing is fixedly connected to the inner wall of the rectangular frame 10. The tapered roller bearing can withstand radial and axial loads, ensuring the stability of the drive shaft 13 and the long shaft 9 during rotation and movement.
[0028] Both the drive shaft 13 and the long shaft 9 are fixedly fitted with bevel gears 14, which mesh with each other. The drive shaft 13 is fitted with a vertical sleeve 15, the top of which is fixedly connected to the bottom of the rectangular frame 10. The vertical sleeve 15 guides and supports the movement of the drive shaft 13. Multiple stirring blades 16 are fixedly connected to the outer wall of the drive shaft 13.
[0029] The stirring blades 16 are designed based on the particle size and shape of wheat seeds. If used for other crop seeds (such as corn, soybeans, etc., which have large differences in particle size), uneven mixing or seed damage may occur due to mismatch in space.
[0030] The inclination angle and discharge chute size of the trapezoidal guide frame 3 are designed specifically for the fluidity of wheat seeds. Its sliding speed is adapted to the gravity density of wheat. When other crop seeds are used, problems such as clogging or excessively fast discharge may occur.
[0031] Working principle: During use, the wheat to be treated is poured into the seed treatment frame 1, and then the prepared pesticide is sprinkled into the seed treatment frame 1, with the material height lower than the bottom height of the U-shaped frame 6. As the second oil cylinder 12 rotates, it drives the rectangular frame 10 to move linearly, and the two guide rods 11 assist the rectangular frame 10 in moving linearly. The movement of the rectangular frame 10 is driven by multiple tapered roller bearings and the vertical sleeve 15, which in turn drives the long shaft 9 and the transmission shaft 13 to move linearly. The linear movement of the long shaft 9 drives the two spur gears 8 to move linearly. Since the two spur gears 8 are located at the top of the two long racks 7 and are positioned at the top of the racks 7, the long shaft 9 drives the two spur gears 8 to move linearly. Due to the meshing relationship, the two spur gears 8 rotate in linear movement, thereby driving the long shaft 9 to rotate. The rotation of the long shaft 9 drives the connected bevel gear 14 to rotate, and the rotation of the bevel gear 14 drives another bevel gear 14 to rotate, which in turn drives the transmission shaft 13 and multiple stirring blades 16 to rotate. This causes the multiple stirring blades 16 to rotate during the movement, thereby achieving a better seed mixing effect. After the seed mixing is completed, the first oil cylinder 5 operates, causing the long strip blocking plate 4 to move downward, exposing the discharge chute. The wheat then enters the trapezoidal guide frame 3 along the discharge chute for discharge and is collected by the existing collection equipment.
[0032] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the first hydraulic cylinder 5, the second hydraulic cylinder 12, and the external pump station to facilitate the control of the overall operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
