Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a portable seed inoculant coating treatment device. Background Technology

[0002] Seed coating is a crucial step in improving seed resistance and germination rate. Seed inoculant coating treatment devices, as the core equipment in this process, are widely used in agricultural production. These devices mainly consist of a funnel-shaped hopper, built-in spiral stirring blades, and a drive motor. After the seeds to be treated are placed in the hopper, coating liquid is poured onto the seed surface. The drive motor rotates the spiral stirring blades, mixing the coating liquid with the seeds to complete the seed coating process. Existing equipment generally relies on manual pouring of the coating liquid into the hopper, and the pouring is often concentrated in a single area where seeds accumulate. Since the seeds naturally accumulate in a cone shape within the funnel-shaped hopper, the coating liquid can only penetrate locally and cannot quickly spread to the entire pile. This directly leads to the dual problems of some seeds being coated with too much liquid and clumping, and some seeds not being in contact with the coating liquid at all. Even extending the stirring time cannot guarantee a uniform coating layer thickness, thus affecting subsequent seed germination and resistance. Summary of the Invention

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figures 1-4 and Figure 8This is the first embodiment of the present invention, which provides a portable seed inoculant coating treatment device. The portable seed inoculant coating treatment device includes a main component 1, including a stirring tank 11. A stirring shaft 12 is provided inside the stirring tank 11, and spiral stirring blades are fixed on the outside of the stirring shaft 12. A discharge pipe 13 is fixed on the lower side of one side of the stirring tank 11. The seeds are poured into the stirring tank 11, and the stirring shaft 12 is started. Then, the coating liquid is poured onto the seeds to complete the seed coating operation. After the seeds are coated, they are discharged out through the discharge pipe 13. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0034] Auxiliary component 2, located above the mixing tank 11, includes a pouring component 21. The pouring component 21 includes a fixed column 211 fixed to the top of the mixing shaft 12. The outside of the fixed column 211 is rotatably connected to a rotating rod 212 via a bearing. One end of the rotating rod 212 extends to the outside of the mixing tank 11, and a pulley is provided at the bottom. The pulley is engaged with the top of the mixing tank 11. A movable block 213 is provided inside the rotating rod 212. A hopper 214 is fixed on one side of the movable block 213. The hopper 214 is funnel-shaped. A positioning plate 215 is fixed inside the rotating rod 212. There are two positioning plates 215, one near the center of the mixing tank 11 and the other near the outer ring of the mixing tank 11. A threaded column 216 is rotatably connected inside the positioning plate 215. A chamber 213-1 is opened inside the movable block 213. A threaded plate 217 is provided inside the chamber 213-1. The threaded plate 217 is threadedly connected to the threaded column 216.

[0035] After the seeds are poured into the mixing tank 11, the bottle containing the coating solution is inverted and inserted into the feeding hopper 214, or the coating solution is poured into the feeding hopper 214. Then, the stirring shaft 12 is started to rotate. At this time, the stirring shaft 12 will drive the rotating rod 212 to rotate through the fixed column 211. The rotating rod 212 drives the feeding hopper 214 to rotate. In the initial state, the feeding hopper 214 will rotate along the outer ring of the mixing tank 11, and the coating solution will be evenly sprinkled along the outer ring of the mixing tank 11. As the rotating rod 212 continues to rotate, the coating solution will be evenly sprinkled along the outer ring of the mixing tank 11. With the continuous rotation of the rotating rod 212, the coating solution will be evenly sprinkled along the outer ring of the mixing tank 11. With one rotation, the threaded column 216 will rotate, and through the cooperation of the threaded plate 217, it will drive the movable block 213 and the feeding hopper 214 to move. This causes the feeding hopper 214 to move towards the center of the mixing tank 11, so that the coating liquid is supplied in a ring from the outer ring to the inner ring of the hopper. This allows the coating liquid to cover the entire radial area and distribute gradually, solving the problems of local clumping and uneven coating from the source. Uniform coating can be achieved without extending the mixing time, which reduces mechanical damage to seeds, ensures germination rate, reduces energy consumption, and greatly improves coating quality and work efficiency.

[0036] Example 2

[0037] Reference Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the auxiliary component 2 also includes a rotating component 22, which includes a gear 221 fixed to the outside of the threaded column 216. A toothed plate 222 is fixed on one side of the mixing tank 11, and the toothed plate 222 cooperates with the gear 221.

[0039] When the rotating rod 212 rotates one revolution, the gear 221 will come into contact with the toothed plate 222, and the two will work together to drive the threaded column 216 to rotate.

[0040] Specifically, the auxiliary component 2 also includes a movable component 23, which includes a fixing block 231 fixed to one side of the threaded plate 217. A first spring 232 is fixed to one side of the fixing block 231, and the other end of the first spring 232 is fixed to the inner wall of the chamber 213-1. When the fixing block 231 is released from its restraint, the first spring 232 will apply a pulling force to the fixing block 231, causing it to drive the threaded plate 217 to separate from the threaded post 216.

[0041] A limiting post 233 is inserted into the fixed block 231, and a limiting hole 213-2 is opened on the movable block 213. The limiting post 233 engages with the limiting hole 213-2. The two work together to lock the positions of the movable block 213 and the threaded plate 217, so that the threaded plate 217 is always connected to the threaded post 216, preventing the two from separating. An elastic metal rod is fixed on one side of the limiting post 233 to apply a pushing force to the limiting post 233, so that the limiting post 233 engages with the limiting hole 213-2 more securely.

[0042] A pusher 234 is fixed on one side of the positioning plate 215 near the center of the mixing tank 11. When the movable block 213 and the hopper 214 move to the position near the center of the mixing tank 11, the pusher 234 will insert into the limiting hole 213-2 and push the limiting post 233 to separate from the limiting hole 213-2. At this time, the restriction on the fixed block 231 is released, and the threaded plate 217 is driven to separate from the threaded post 216 by the first spring 232. At this time, the second spring 235 will apply a pulling force to the movable block 213, so that it moves to the initial position. Then, the threaded post 216 needs to be continuously rotated in the opposite direction, which can save operation time.

[0043] A second spring 235 is fixed on one side of the movable block 213, and the other end of the second spring 235 is fixed to the positioning plate 215 near the outer ring of the mixing tank 11.

[0044] Specifically, a rod 236 is inserted into the movable block 213. An elastic compression sleeve is fixed on one side of the rod 236 to apply elastic thrust to the rod 236. A hole 212-1 is opened on the rotating rod 212. When the pusher 234 is inserted into the limiting hole 213-2, the rod 236 will coincide with the hole 212-1. At this time, the elastic compression sleeve pushes the rod 236 to engage with the hole 212-1. The two work together to lock the movable block 213 in the current position. At this time, the coating liquid inside the hopper 214 has been completely drained, and the hopper 214 stops rotating and moving. After the stirring is completed, press the rod 236 to separate it from the hole 212-1.

[0045] A force-bearing block 237 is fixed on one side of the fixed block 231, and a push rod 238 is fixed on one side of the positioning plate 215. The end of the push rod 238 is inclined. When the second spring 235 pulls the movable block 213 to reset, the inclined surface at the end of the push rod 238 will apply a pushing force to the force-bearing block 237, causing it to move the fixed block 231 and the threaded plate 217, so that the threaded plate 217 is connected to the threaded post 216. At the same time, the limiting post 233 coincides with the limiting hole 213-2, and under the elastic force of the elastic metal rod, the two are engaged again.

[0046] Specifically, the auxiliary component 2 also includes a connector 24, which includes a positioning post 241 inserted into the rotating rod 212. The fixing post 211 has a positioning hole 211-1. The positioning post 241 engages with the positioning hole 211-1. The two cooperate to connect the fixing post 211 to the rotating rod 212, so that when the fixing post 211 rotates, it can drive the fixing post 211 to rotate.

[0047] There are multiple positioning holes 211-1, which are evenly distributed in a ring on the outside of the fixing post 211. One end of the positioning post 241 is fixed with a third spring 242, and the other end of the third spring 242 is fixed with the positioning plate 215. The third spring 242 is used to apply a pushing force to the positioning post 241, so that the positioning post 241 and the positioning hole 211-1 are engaged more tightly.

[0048] The positioning post 241 has a slot 241-1, and a rotating rod 243 is inserted into the slot 241-1. The center of the rotating rod 243 is rotatably connected to the rotating rod 212 through a rotating shaft. A movable post 244 is inserted into the positioning plate 215, and one end of the movable post 244 is in contact with the rotating rod 243.

[0049] When the movable block 213 moves to a position close to the center of the mixing tank 11 and the insertion rod 236 engages with the insertion hole 212-1, the movable block 213 will push the movable column 244 to move, causing the movable column 244 to push the rotating rod 243 to rotate. The bottom end of the rotating rod 243 will press against the inner wall of the slot 241-1 and drive the positioning column 241 to move, causing the positioning column 241 to separate from the positioning hole 211-1 and the fixed column 211 to separate from the rotating rod 212. Therefore, after all the coating liquid inside the hopper 214 is poured onto the seeds, the rotating shaft 12 and the fixed column 211 will not drive the rotating rod 212 to continue rotating when they rotate. In the subsequent rotation process, the seeds and coating liquid can be fully mixed by the stirring shaft 12, and stopping the rotation of the rotating rod 212 will not hinder the staff from observing the coating status of the seeds.

[0050] Example 3

[0051] Reference Figure 9 and Figure 10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0052] Specifically, the auxiliary component 2 also includes a sealing component 25, which includes a baffle 251 located inside the hopper 214. The baffle 251 seals the coating liquid inside the hopper 214 to prevent the coating liquid from leaking downwards before the rotating rod 212 starts to rotate.

[0053] A rotating column 252 is inserted into the baffle 251. The two ends of the rotating column 252 are round and the middle part is rectangular. The rectangular part is movably connected to the inside of the baffle 251. The rotating column 252 is used to drive the baffle 251 to rotate, thereby opening the baffle 251 and allowing the coating liquid to flow downward. The baffle 251 can also move axially outside the rotating column 252.

[0054] A stabilizing rod 253 is fixed to one side of the rotating rod 212, and the rotating column 252 is rotatably connected to the stabilizing rod 253 through a bearing.

[0055] Specifically, the auxiliary component 2 also includes a trigger 26, which includes a rotating plate 261 fixed to the end of the rotating column 252. A counterweight plate is fixed above the end of the rotating plate 261 to apply downward rotational force to the rotating plate 261. A movable sleeve 262 is sleeved on the outside of the fixed column 211. A pressing rod 263 is fixed on one side of the movable sleeve 262. The pressing rod 263 is L-shaped and its top end contacts the rotating plate 261.

[0056] Specifically, a rotating plate 264 is hinged to the outside of the fixed column 211, and a counterweight 265 is fixed to the bottom of the rotating plate 264. There are multiple rotating plates 264 and counterweights 265, which are evenly distributed in a ring on the outside of the fixed column 211.

[0057] When the fixed column 211 rotates, the resulting centrifugal force causes the rotating plate 264 to rotate upwards. The rotating plate 264 pushes the movable sleeve 262 and the extrusion rod 263 upwards, causing the extrusion rod 263 to push the rotating plate 261 to rotate. The rotating plate 261 then drives the rotating column 252 and the baffle 251 to rotate, thereby opening the baffle 251 and allowing the coating liquid to flow downwards. As the rotation speed of the fixed column 211 increases, the centrifugal force on the rotating plate 264 increases, and the stroke by which it pushes the movable sleeve 262 and the extrusion rod 263 upwards increases. Therefore, the opening angle of the baffle 251 increases, allowing the fixed column 211 to rotate faster and the coating liquid to flow outwards at a greater flow rate. This enables on-demand liquid supply and avoids over- or under-supply.

[0058] Specifically, a guide post 266 is fixed at the bottom of the rotating rod 212. The bottom end of the guide post 266 passes through the extrusion rod 263 and is movably connected to the extrusion rod 263. The guide post 266 is T-shaped and supports the extrusion rod 263 at its bottom. This allows the extrusion rod 263 to move downwards a specified distance due to the weight of the rotating plate 261, after which it can no longer move downwards. This supports the rotating plate 261 and prevents the rotating plate 261 from rotating downwards too much, which would cause the baffle 251 to be unable to be in a horizontal state.

[0059] In use, after the seeds are poured into the mixing tank 11, the bottle containing the coating solution is inverted and inserted into the feeding hopper 214, or the coating solution is poured into the feeding hopper 214. Then, the mixing shaft 12 is started to rotate. At this time, the mixing shaft 12 will drive the fixed column 211 to rotate. When the fixed column 211 rotates, the centrifugal force generated will cause the rotating plate 264 to rotate upward. The rotating plate 264 will push the movable sleeve 262 and the extrusion rod 263 to move upward, so that the extrusion rod 263 pushes the rotating plate 261 to rotate. 61 drives the rotating column 252 and baffle 251 to rotate, which in turn opens the baffle 251 and allows the coating liquid to flow downward. As the rotation speed of the fixed column 211 increases, the centrifugal force on the rotating plate 264 increases, and the stroke that pushes the movable sleeve 262 and the extrusion rod 263 upward increases. Therefore, the opening angle of the baffle 251 will increase, so the faster the fixed column 211 rotates, the greater the flow rate of the coating liquid, thus achieving on-demand liquid supply and avoiding over- or under-supply.

[0060] When the fixed column 211 rotates, it drives the rotating rod 212 to rotate, which in turn drives the feeding hopper 214 to rotate. In the initial state, the feeding hopper 214 rotates along the outer ring of the mixing tank 11, and the coating liquid is evenly sprinkled along the outer ring of the mixing tank 11. As the rotating rod 212 continues to rotate, after the rotating rod 212 rotates one revolution, the gear 221 will contact the toothed plate 222, and the two will drive the threaded column 216 to rotate. Through the cooperation of the threaded plate 217, the movable block 213 and the feeding hopper 214 will move, causing the feeding hopper 214 to move towards the center of the mixing tank 11. This allows the coating liquid to be supplied in a ring from the outer ring of the hopper to the inner ring, so that the coating liquid can be radially fully covered and gradually distributed. This solves the problems of local clumping and uneven coating from the source. Uniform coating can be achieved without extending the stirring time, which reduces mechanical damage to seeds, ensures germination rate, reduces energy consumption, and greatly improves coating quality and work efficiency.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
