Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically a seed dressing device for wheat planting. Background Technology

[0002] In wheat cultivation, seed treatment with pesticides is currently necessary to control underground pests and diseases. Due to the widespread adoption of agricultural machinery, many farmlands now operate mechanically, and seed treatment for wheat is performed using specialized devices. However, an existing wheat seed treatment device (publication number: CN217445791U) has the following drawbacks:

[0003] In existing seed coating devices, wheat seeds and pesticides are added directly from above to the coating tank, easily leading to accumulation areas at the bottom or sides of the tank. The accumulated material doesn't make proper contact with the mixing blades, requiring extended mixing time to loosen it again. This not only prolongs the work cycle but also increases energy consumption and equipment wear, severely limiting mixing efficiency. Because the material often circulates within the tank without being thoroughly agitated, some seeds have excessive pesticide concentration on their surface, while others are barely coated, resulting in poor coating uniformity. To improve the coating effect, operators often increase the mixing speed, but this causes violent collisions between seeds, leading to seed coat damage and increased fragmentation, thus reducing germination rate and seedling quality. Furthermore, accumulated residues adhere to the tank walls and mixing blades, requiring manual removal during cleaning, which is time-consuming and labor-intensive; incomplete cleaning can also lead to cross-contamination of pesticides. Traditional equipment is mostly designed intermittently, requiring shutdown for each loading, unloading, and cleaning, preventing continuous production and further impacting overall operational efficiency. Finally, the existing equipment lacks real-time monitoring of the material distribution and mixing state inside the drum. Operators can only rely on experience to determine when to stop mixing, making precise control difficult. Prolonged high-load operation of the motor also exacerbates wear on bearings and transmission components, significantly increasing maintenance costs. Utility Model Content

[0004] The main purpose of this invention is to provide a seed dressing device for wheat cultivation, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A seed treatment device for wheat cultivation includes a mixing device, a feeding bracket, and a conveyor belt. A drug delivery assembly is mounted on the side of the feeding bracket, and the drug delivery assembly is connected to three atomizing nozzles. The drug delivery assembly is connected to a water pump via a pipe. The mixing device is located on the side of the feeding bracket, and a mixing motor is mounted on one side of the mixing device. The motor is connected to a hollow mixing shaft, and the other side of the hollow mixing shaft is connected to the mixing device's water pump via a pipe.

[0007] Furthermore, the hollow stirring shaft is provided with medicine outlet holes.

[0008] Furthermore, a conveyor belt is provided in the middle of the feeding bracket, and a motor is connected to the power output end of the conveyor belt.

[0009] Furthermore, a guide plate is provided at the end of the conveyor belt.

[0010] Furthermore, the water pump is connected to the medicine box via a pipe.

[0011] Furthermore, the water pump of the stirring device is connected to the medicine box via a pipe.

[0012] Furthermore, the atomizing nozzle is positioned above the conveyor belt.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Firstly, by utilizing the coordinated operation of the feeding support and conveyor belt, wheat seeds are continuously pushed along the guide plate into the mixing area, completely eliminating the traditional intermittent "loading-stopping-unloading" operation mode. The seeds enter the mixing cycle during transport, eliminating the need for prolonged accumulation in the same container, thus significantly increasing the seed mixing capacity per unit time. To ensure initial uniform coating of the agent, the agent delivery assembly on the side of the feeding support uses three atomizing nozzles to finely spray the liquid onto the seed surface on the conveyor belt; simultaneously, pipes inside the hollow mixing shaft pump the liquid into the shaft via a water pump, and then inject it directly into the churning seed pile through evenly distributed outlet holes on the shaft wall. This dual action of surface pre-coating and internal injection allows the agent to quickly penetrate into the seed mass, avoiding the "dry-then-wet" phenomenon common in traditional mixing drums. Since the seeds have been adequately moistened and coated with the agent, the main mixing motor can gently agitate at a lower speed, effectively breaking up any remaining small clumps without causing damage to the seed coat or producing broken particles. This ensures thorough seed treatment while maintaining the seed germination rate and seedling quality. Attached Figure Description

[0023] Example

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A seed treatment device for wheat cultivation includes a mixing device 1, a feeding bracket 2, and a conveyor belt 3. A pesticide delivery assembly 12 is mounted on the side of the feeding bracket 2. The pesticide delivery assembly 12 is connected to three atomizing nozzles 11. The pesticide delivery assembly 12 is connected to a water pump 7 via a pipe 9. The mixing device 1 is located on the side of the feeding bracket 2. A mixing motor 6 is mounted on one side of the mixing device 1. The motor 6 is connected to a hollow mixing shaft 13. The other side of the hollow mixing shaft 13 is connected to the mixing device water pump 8 via a pipe 9.

[0026] Furthermore, the hollow stirring shaft 13 is provided with medicine outlet holes.

[0027] Furthermore, a conveyor belt 3 is provided in the middle of the feeding bracket 2, and a motor 4 is connected to the power output end of the conveyor belt 3.

[0028] Furthermore, a guide plate 5 is provided at the end of the conveyor belt 3.

[0029] Furthermore, the water pump 7 is connected to the medicine box 10 via the pipe 9.

[0030] Furthermore, the stirring device water pump 8 is connected to the medicine box 10 via a pipe 9.

[0031] Furthermore, the atomizing nozzle 11 is positioned above the conveyor belt 3.

[0032] Wheat seeds are fed into the inlet of the feeding bracket 2 by the operator, carried by the conveyor belt 3, and driven by the motor 4 to move forward at a constant speed along the feeding bracket 2. The guide plate 5 at the end of the conveyor belt 3 provides final directional guidance to the seeds, which are then directly fed into the mixing device 1 located on the side of the feeding bracket 2. This completely eliminates the traditional intermittent "loading-stopping-unloading" operation and ensures continuous flow of seeds throughout the entire seed mixing process.

[0033] The feeding bracket 2 has a drug delivery assembly 12 installed on its side support, and three atomizing nozzles 11 are evenly distributed above the conveyor belt 3. When the water pump 7 draws the drug solution from the drug box 10 and delivers it to the drug delivery assembly 12 through the pipe 9, the drug solution is finely atomized and sprayed onto the surface of the moving seeds through the atomizing nozzles 11, completing the initial surface pre-coating.

[0034] The seeds then enter the chamber of the mixing device 1. A mixing motor 6 is mounted on one side of the mixing device 1, and the torque output of the motor 6 is transmitted to the hollow mixing shaft 13, causing it to rotate slowly. Simultaneously, the water pump 8 of the mixing device draws liquid from the reagent box 10, delivers the liquid through pipe 9 into the hollow mixing shaft 13, and evenly sprays it into the seed pile through a series of unlabeled nozzles on the shaft wall. This dual action of surface pre-coating and hollow injection ensures that the reagent covers both the outer layer of the seeds and penetrates into the seed cluster.

[0035] Since the seeds have been fully moistened, the stirring motor 6 can turn them over at a lower speed, which can not only thoroughly break up the residual material pile, but also avoid the damage to the seed coat and the proliferation of fragments caused by traditional high-speed impact, thus maximizing the seed germination rate and seedling vigor.
