Description

Technical Field

[0001] This utility model relates to the field of seed processing technology, specifically to a seed coating device. Background Technology

[0002] Seed coating is a seed treatment technology that coats the surface of the seed to form a film. Compared with the traditional method of sowing seeds and then applying fertilizer and pesticides at the appropriate time, this technology improves the survival rate and yield of seeds.

[0003] Traditional seed coating devices add seeds and coating agents together into a mixing tank and then mix them. During the rotation of the mixing structure, the seeds are easily damaged by shear forces, which affects the quality of the seeds. At the same time, the mixing structure inside the tank is difficult to clean. If the residual coating agent deteriorates, it will affect the quality of subsequent seed coating. Utility Model Content

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figures 1-6As shown, this utility model provides a technical solution: a seed coating device, including a base 1, a non-destructive coating mechanism 2 on the top of the base 1, an auxiliary adding mechanism 3 on the left side of the non-destructive coating mechanism 2, the non-destructive coating mechanism 2 including a first stand 21 and a second stand 22, the first stand 21 being fixedly installed on the top of the base 1, the second stand 22 being fixedly installed on the top of the base 1 and located to the right of the first stand 21, a rotating shaft 23 being rotatably connected to the adjacent sides of the first stand 21 and the second stand 22, a coating tank 25 being fixedly installed between the adjacent sides of the two rotating shafts 23, a servo motor 24 being fixedly installed to the right side of the second stand 22, the output shaft of the servo motor 24 being fixedly connected to the right side of the rotating shaft 23 located on the right side, a hemispherical cover 253 being movably connected to the top of the coating tank 25, and a connecting... A plug-in block 252 is fixedly installed on the outer wall of the frame 251 and the hemispherical cover 253. The plug-in block 252 is movably inserted into the inner cavity of the connecting frame 251. A positioning bolt is threaded onto the outer wall of the connecting frame 251. The threaded end of the positioning bolt is movably connected to the outer wall of the plug-in block 252. First, the coating agent and seeds are added into the inner cavity of the coating tank 25. Then, the hemispherical cover 253 is installed on the top of the coating tank 25, causing the plug-in block 252 to be inserted into the inside of the connecting frame 251. Then, the positioning bolt on the connecting frame 251 is tightened to lock the hemispherical cover 253. Next, the servo motor 24 is controlled to work. Through the transmission of the rotating shaft 23, the coating tank 25 is rotated as a whole, so that the seeds are repeatedly turned over in the coating tank 25 and the hemispherical cover 253. This can promote the coating agent to be evenly coated on the outer surface of the seeds, achieving the function of non-destructive coating.

[0031] As one implementation method in this embodiment, such as Figure 2 , Figure 3 As shown, the first support 21 and the second support 22 are detachably connected to mounting feet 26 on both the front and back. Support rods 261 are welded to the outer walls of the mounting feet 26. Elastic elements 262 are fixedly connected to the adjacent sides of the two support rods 261. A solid rubber ball 263 is fixedly installed at the end of the elastic element 262 away from the support rod 261. During the rotation of the coating tank 25 and the hemispherical cover 253, their outer walls will impact the solid rubber ball 263 slightly. This impact will cause the coating tank 25 and the hemispherical cover 253 to vibrate, causing the seeds adhering to the inner walls of the coating tank 25 and the hemispherical cover 253 to fall off, further improving the uniformity of seed coating. Through the design of the elastic element 262, the solid rubber ball 263 can be pushed by the coating tank 25 or the hemispherical cover 253 and then reset.

[0032] As one implementation method in this embodiment, such as Figure 1 , Figure 5 , Figure 6As shown, the auxiliary adding mechanism 3 includes a fixing sleeve 31, which is fixedly installed on the left side of the first support 21. A weighing sensor 32 is fixedly installed on the top of the fixing sleeve 31, and an annular sleeve 33 is fixedly installed on the top of the weighing sensor 32. A temporary storage tank 35 is fixedly installed on the inner wall of the annular sleeve 33. A display screen 34 is fixedly installed on the bottom of the fixing sleeve 31. The display screen 34 is used to display the weight information monitored by the weighing sensor 32. A recessed seat 351 is fixedly installed on the bottom of the inner wall of the temporary storage tank 35. A pump 36 is fixedly installed on the top of the temporary storage tank 35, and the input pipe of the pump 36 extends to the temporary storage tank. Near the bottom of the inner cavity of storage tank 35, a three-way pipe 37 is fixedly connected to the output pipe of pump 36. A second valve 372 is fixedly connected to the top of the three-way pipe 37, and a flexible hose 373 is fixedly connected to the top of the second valve 372. A first valve 371 is fixedly connected to the bottom of the three-way pipe 37. A hollow ring 352 is fixedly installed on the inner wall of storage tank 35, and a ring mesh 353 is fixedly installed on the inner wall of the hollow ring 352. A return pipe 354 is fixedly connected to the top of the hollow ring 352, and the top of the return pipe 354 is fixedly connected to the bottom of the first valve 371. The coating agent is pre-added to the inner cavity of storage tank 35. Close valve 372 and open valve 371 to operate pump 36. This allows coating agent to be drawn from the bottom of the storage tank 35 and then transported through the tee pipe 37 and return pipe 354 into the inner cavity of the hollow ring 352. The coating agent then flows back through the annular mesh 353 into the inner cavity of the storage tank 35, achieving a circulating mixing function and preventing sedimentation from long-term storage, which could affect the effectiveness of the coating agent. Opening valve 372 and closing valve 371 allows pump 36 to operate, drawing coating agent from the inner cavity of the storage tank 35 and outputting it from the end of the hose 373. The hose 373... The length can be extended to the inner cavity of the coating tank 25. The weighing sensor 32 is an existing structure, and the model of the weighing sensor 32 can be selected as SB-300kg. The weighing sensor 32 and the display screen 34 are connected by a controller electrical signal. The weighing sensor 32 can monitor the overall weight of the temporary storage tank 35. When the pump 36 is working, the change in the overall weight of the temporary storage tank 35 is the output amount of the coating agent. The user can observe the output amount of the coating agent from the display screen 34, which makes it convenient for the user to accurately control the amount of coating agent added, reduce the waste rate of the coating agent, and ensure the fullness of seed coating.

[0033] Working principle: First, a certain amount of seeds are added to the inner cavity of the coating tank 25. Then, the pump 36 is controlled to work, delivering a certain amount of coating agent into the coating tank 25 from the end of the hose 373. Next, the hemispherical cap 253 is installed on the top of the coating tank 25. Then, the servo motor 24 is controlled to work, driving the coating tank 25 to rotate as a whole through the transmission of the rotating shaft 23. This causes the seeds to repeatedly turn over inside the coating tank 25 and the hemispherical cap 253, thereby promoting the coating agent to evenly coat the outer surface of the seeds. After coating is completed, the hemispherical cap 253 is removed from the top of the coating tank 25, and the seeds can be scooped out from the inner cavity of the coating tank 25.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
