Abstract
Description
Technical Field
[0001] This utility model belongs to the field of seed dressing agents, and particularly relates to a seed dressing agent device. Background Technology
[0002] Seed dressing is an important seed treatment technology in agricultural production. It mainly involves mixing seeds with pesticides, micronutrients, and other seed dressing agents, so that the agents are evenly attached to the seed surface and form a protective film, thereby achieving the purpose of preventing and controlling pests and diseases, promoting seed germination, and seedling growth.
[0003] When using seed dressing agents, the seeds are first poured into a seed dressing bucket, and then stirred with a stirring paddle. Simultaneously, the seed dressing agent is applied into the bucket. Most existing application methods use external spray devices, which often result in limited coverage and easy splashing and loss of the pesticide during stirring, leading to both waste of the agent and environmental pollution.

[0015] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model 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 of the present utility model and are not intended to limit the scope of the present utility model.
[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0017] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.
[0018] Combination Figures 1-4 As shown, the seed dressing device includes a workbench 1, a column 2 on the workbench 1, a liftable top frame 3 on the column 2, a stirring shaft 4 rotatably mounted at the front end of the top frame 3, and a stirring motor 5 for driving the stirring shaft 4 to rotate at the rear end. A stirring paddle 6 is mounted at the bottom of the stirring shaft 4. An inner cavity 7 is opened above the stirring shaft 4. Both the upper and lower ends of the inner cavity 7 are connected to joints, wherein the upper joint 81 is rotatably sealed and installed, and the lower joint 82 is fixedly installed. The lower joint 82 is connected to a spray pipe 9, which is a metal pipe. The lower part of the spray pipe 9 is bent outward and installed below the stirring paddle 6.
[0019] This device can be used to mix seeds with pesticides, micronutrients, and other seed dressing agents to achieve seed dressing. This allows the agent to adhere evenly to the seed surface, forming a protective film, thereby achieving the purpose of preventing and controlling pests and diseases, promoting seed germination, and seedling growth.
[0020] Figures 1-2 In this device, a clamping mechanism 10 is provided on the column 2 facing the stirring shaft. The upper connector is connected to the outlet of the spraying assembly via a flexible hose. When using this device for seed mixing, with the top frame at its highest position, the seed mixing bucket is first placed on the worktable as required. The clamping mechanism clamps and fixes the seed mixing bucket on the worktable. The top frame moves downward, and the stirring paddle extends to the bottom of the bucket. Then, an appropriate amount of seeds is poured into the seed mixing bucket. Finally, the stirring motor drives the stirring shaft to rotate, and the stirring paddle stirs the seeds in the bucket. At the same time, the spraying pipe sprays out the seed mixing agent, which is evenly sprayed onto the seed layer, achieving seed mixing without splashing the seed mixing agent. After a period of seed mixing, the stirring shaft stops rotating, the outlet of the spraying assembly closes, the top frame moves to its highest position, and the clamping mechanism is opened to remove the seed mixing bucket.
[0021] In this embodiment, as Figure 2 The top frame 3 is equipped with a drive wheel 11 that rotates inside, and the stirring shaft 4 is equipped with a driven wheel 12. A belt 13 is fitted between the drive wheel 11 and the driven wheel 12. The drive shaft of the stirring motor 5 is connected to the drive wheel 11.
[0022] As a preferred structure, the stirring shaft 4 and the stirring paddle 6 are respectively provided with two baffles 14 corresponding to the upper and lower parts of the spraying pipe. The upper baffle is L-shaped, and the lower baffle is set perpendicular to the bottom surface of the stirring paddle to form a protective zone. The lower part of the spraying pipe is installed in the protective zone, and the upper part of the spraying pipe is installed in the L-shaped upper baffle. The baffles protect the spraying pipe and prevent it from being damaged during the rotation of the stirring shaft, thereby improving the service life of the spraying pipe.
[0023] In this device, such as Figure 2 , Figure 4 The top frame 3 is provided with a bracket 15, the bracket 15 is provided with a top sleeve 16, the stirring shaft 4 is rotatably provided inside the top sleeve 16, the top sleeve 16 has an installation hole communicating with the inner cavity 7, and the upper connector 81 is provided in the installation hole.
[0024] In the above structure, the bracket serves as a carrier for mounting the top sleeve. The stirring shaft is rotatably mounted inside the top sleeve. The upper connector communicates with the top hole of the inner cavity through a mounting hole, and the upper connector is connected to the outlet of the spraying assembly through a flexible hose. When this device coats the seeds in the seed-coating tank, the seed-coating agent flows from the flexible hose into the inner cavity, and then is evenly sprayed onto the seeds through the spraying pipe.
[0025] Furthermore, as a preferred structure, such as Figures 1-2 The column 2 is slidably provided with a push column 17, and the top frame 3 is provided above the push column 17. The push column 17 is provided with an inner sleeve 18 located on the worktable. The top of the inner sleeve 18 is provided with a threaded sleeve 19. The inner sleeve 18 contains a lead screw 20. The threaded sleeve 19 and the top frame 3 are sequentially passed through the lead screw 20. The top frame 3 is provided with a lifting motor 21 for driving the lead screw 20 to rotate.
[0026] As shown in the diagram, a rotating sleeve 22 is also provided inside the top frame, and the lead screw is rotatably installed inside the rotating sleeve. When the top frame needs to be raised or lowered, the lifting motor drives the lead screw to rotate. During the rotation of the lead screw, the lead screw moves vertically within the sleeve, pushing the top frame to move vertically. At the same time, the pushing column slides within the column, making the entire raising and lowering process more stable.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
