Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, specifically to a seed coating device for oat cultivation. Background Technology

[0002] Seed coating refers to the process of using adhesives or film-forming agents and specific seed coating equipment to coat non-seed materials such as fungicides, insecticides, micronutrients, and plant growth regulators on the outside of seeds. This process aims to improve stress resistance, disease resistance, accelerate germination, promote seedling establishment, increase yield, and improve quality. Seeds coated with seed coating agents can quickly absorb water and swell after sowing. As the embryo inside the seed gradually develops and the seedling grows, the various effective components contained in the seed coating agent are slowly released and gradually absorbed by the seedling. This achieves the purpose of preventing and controlling seedling diseases and pests, promoting growth and development, and increasing crop yield. Seed coating equipment is used when coating oat seeds.

[0003] According to patent publication number CN 214413446 U, a seed coating device for oat cultivation is disclosed. This device uses a spiral blade and a stirring rod in combination, which not only saves on the agent but also makes the coating uniform and does not affect the production quality of the seeds. By using an insulation layer and a heating layer, the internal temperature of the equipment can be kept constant during seed coating, providing a good working environment for the seeds. However, the stirring rod of this device has a poor stirring effect and cannot effectively stir the seeds, thus affecting the contact effect between the seeds and the agent, and consequently affecting the seed coating effect.

[0004] To address this issue, we propose a seed coating device for oat cultivation. Utility Model Content

Detailed Implementation

[0031] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-6As shown, this utility model provides a technical solution: a seed coating device for oat cultivation, including a coating cylinder 1, a discharge pipe 2 connected to the bottom of the coating cylinder 1, a first box cover 6 fixedly installed on the upper part of the coating cylinder 1, a feed hopper 5 connected to the left side of the coating cylinder 1 via a connecting pipe, a reagent box 4 connected to the upper part of the first box cover 6 via a support pipe, and a connecting assembly 3 between the coating cylinder 1 and the reagent box 4. The connecting assembly 3 includes a stirring mechanism 31 installed inside the coating cylinder 1, an auxiliary mechanism 32 installed inside the reagent box 4, an electrically controlled valve 1 installed at the bottom of the discharge pipe 2, and an electrically controlled valve 2 installed inside the support pipe. The stirring mechanism 31 includes a first rotating shaft 311 rotatably connected to the inside of the first box cover 6 via a bearing. An installation sleeve 313 is fitted on the outer wall of the first rotating shaft 311, and a spiral blade 312 is fixedly connected to the outer wall of the bottom end of the first rotating shaft 311. The outer wall of the installation sleeve 313 is fixedly connected to... A first stirring rod 314 is connected to the first rotating shaft 311. A groove 315 is formed on the outer wall of the first rotating shaft 311. A sliding rod 316 is fixedly connected to the inner wall of the groove 315. A slider 317 is slidably connected to the outer wall of the sliding rod 316. A first spring 318 is fixedly connected to the inner wall of the groove 315. A pressure ring 319 is fixedly connected to the bottom of the first cover 6. A rectangular rod 3110 is fixedly connected to the outer wall of the mounting sleeve 313. A pressure rod 3111 is fixedly connected to the upper part of the rectangular rod 3110. The top of the rod 3111 is equipped with a ball bearing. The inside of the feed hopper 5 is provided with an installation groove 3112. An installation frame 3113 is inserted into the installation groove 3112. A filter plate 3114 is fixedly connected inside the installation frame 3113. A pressing groove 3115 is provided at the bottom of the installation frame 3113. An inner groove 3116 is provided inside the feed hopper 5. A pressing column 3117 is sleeved inside the inner groove 3116. A second spring 3118 is fixedly connected to the inner wall of the inner groove 3116.

[0034] In this embodiment, the first rotating shaft 311 is rotatably connected to the second box cover 321 via a bearing.

[0035] Furthermore, the outer side of the slider 317 is fixedly connected to the mounting sleeve 313, and one end of the first spring 318 is fixedly connected to the slider 317. Through the cooperation of the first rotating shaft 311, the spiral blade 312, the mounting sleeve 313, the first stirring rod 314, the slide groove 315, the slide rod 316, the slider 317, the first spring 318, the pressure ring 319, the rectangular rod 3110, and the pressure rod 3111, the first stirring rod 314 can move up and down reciprocally during rotation, thereby achieving a better stirring effect on the seeds, a better contact effect between the seeds and the agent, and thus a better coating effect on the seeds.

[0036] Furthermore, one end of the second spring 3118 is fixedly connected to the pressing column 3117, and the pressing column 3117 is pressed against the pressing groove 3115. The seeds added to the coating cylinder 1 can be filtered through the filter plate 3114, which can prevent damp and clumped materials from entering the coating cylinder 1 and affecting the subsequent coating effect. Through the cooperation of the mounting groove 3112, mounting frame 3113, filter plate 3114, pressing groove 3115, inner groove 3116, pressing column 3117 and second spring 3118, it is easy to manually disassemble and clean the filter plate 3114, which can prevent the filter holes of the filter plate 3114 from being blocked and affecting subsequent use.

[0037] Furthermore, there are two pressure columns 3117, symmetrically distributed within the feed hopper 5.

[0038] In use, the device is operated by a motor 322 that drives the first rotating shaft 311 to rotate. Seeds requiring coating are then manually added from the feed hopper 5 into the coating cylinder 1. When the first rotating shaft 311 rotates, the sliding rod 316 and the slider 317 limit the movement, causing the mounting sleeve 313, fixedly connected to the outside of the slider 317, to drive the first stirring rod 314 to rotate synchronously, thus initially stirring the seeds. Then, by opening the second electrically controlled valve, the agent in the discharge pipe 2 flows through the support pipe into the coating cylinder 1, allowing for seed coating. When the mounting sleeve 313 rotates, the rectangular rod 3110 drives the pressure rod 3111 to rotate synchronously. Under the elastic force of the first spring 318, the ball bearing at the top of the pressure rod 3111 slides relative to the pressure ring 319, thus securing the connection. The first stirring rod 314 on the outer wall of the mounting sleeve 313 moves up and down during rotation, which can better stir the seeds and improve the contact between the seeds and the agent, thus improving the seed coating effect. When the first rotating shaft 311 rotates, the spiral blades 312 rotate synchronously, which can transport the seeds at the bottom of the coating cylinder 1 upward, further enhancing the seed coating effect. Furthermore, when the filter plate 3114 is disassembled and cleaned, it can be installed by simply inserting the mounting frame 3113 into the mounting groove 3112 manually. Then, under the action of the second spring 3118, the pressure column 3117 can press against the pressure groove 3115, thus fixing the mounting frame 3113 in the mounting groove 3112, thereby completing the installation operation. The operation is simple and convenient.

[0039] Example 2

[0040] Based on Example 1, a preferred embodiment of the seed coating device for oat cultivation provided by this utility model is as follows: Figures 1 to 6As shown: The auxiliary mechanism 32 includes a second stirring rod 323 and a rotating rod 324 fixedly connected to the outer wall of the first rotating shaft 311. One end of the rotating rod 324 is rotatably connected to the second rotating shaft 325 via a bearing. A conveying blade 326 is fixedly connected to the outer wall of the second rotating shaft 325. A gear 327 is fixedly connected to the outer wall of the bottom end of the second rotating shaft 325. A gear ring 328 is fixedly connected to the inner wall of the medicine tank 4. A second tank cover 321 is fixedly installed on the top of the medicine tank 4. A motor 322 is fixedly installed on the upper part of the second tank cover 321 via a mounting bracket. A feed pipe 329 is connected to the upper part of the second tank cover 321.

[0041] In this embodiment, gear 327 and gear ring 328 are meshed together. Through the cooperation of second cover 321, motor 322, second stirring rod 323, rotating rod 324, second rotating shaft 325, conveying blade 326, gear 327, gear ring 328, and feed pipe 329, the medicine in the medicine tank 4 can be stirred, which can prevent the medicine from settling and affecting subsequent use.

[0042] Furthermore, a sealing cap is provided at the top of the feed pipe 329.

[0043] Furthermore, the output end of the motor 322 is fixedly connected to the first rotating shaft 311.

[0044] When the motor 322 drives the first rotating shaft 311 to rotate, the second stirring rod 323, which is fixedly connected to the outer wall of the first rotating shaft 311, can rotate synchronously, thereby stirring the medicine in the medicine tank 4 and preventing the medicine from settling, which would affect its subsequent use. When the first rotating shaft 311 rotates, the rotating rod 324 can drive the second rotating shaft 325 and the gear 327 to rotate synchronously. Since the gear 327 is meshed with the gear ring 328, the conveying blade 326, which is fixedly connected to the outer wall of the second rotating shaft 325, can rotate on its own axis while revolving around the revolution, thereby conveying the medicine at the bottom of the medicine tank 4 upward, which can further prevent the medicine from settling.
