Description

Technical Field

[0001] The utility model relates to the technical field of corn seed coating, in particular to a corn seed coating machine. Background Art

[0002] Seed coating technology refers to the process of evenly coating the seed surface with a seed coating agent containing multiple ingredients such as insecticides, fungicides, compound fertilizers, trace elements, plant growth regulators, slow-release agents and film-forming agents in a certain proportion to form a smooth and firm drug film. It has the characteristics of comprehensive prevention and control, low toxicity and high efficiency, saving seeds and medicines, protecting the environment, and having a high input-output ratio.

[0003] In the existing corn seed coating machines, when the corn seeds are placed in a mixing barrel, the staff will add the coating agent from the port of the mixing barrel, and then stir the barrel to evenly coat the corn seeds. However, in this process, the coating agent first contacts the corn seeds in the upper layer, which will make it difficult for the corn seeds in the remaining areas to be evenly mixed with the coating agent, which will easily lead to large differences in the degree of coating on the surface of the seeds after mixing, and even incomplete coating of some seeds. In view of this, we propose a corn seed coating machine to solve this problem. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a corn seed coating machine, comprising a stirring barrel and a mounting assembly for fixing the stirring barrel, the inner wall of the stirring barrel is fixedly mounted with a fixed cover, the outer wall of the fixed cover is rotatably mounted with a movable cover, a plurality of stirring rods are fixedly mounted on the surface of the movable cover, an auger assembly for moving the bottom corn is also arranged inside the fixed cover, wherein the auger assembly comprises a rotating rod, an auger blade is fixedly mounted on the surface of the rotating rod, a driving assembly for driving the movable cover and the auger blade to rotate is also arranged on the surface of the stirring barrel, an inner cavity is also provided inside the stirring barrel, a blanking plate is fixedly mounted on the inner wall of the inner cavity, the surface of the blanking plate is inclined and spirally wound inside the inner cavity, a plurality of injection channels connected to the inner cavity are also provided on the inner wall of the stirring barrel, a filter plate is fixedly mounted on the inner wall of the injection channel, a first injection pipe is fixedly mounted on the top of the stirring barrel, and a second injection pipe is fixedly mounted on the outer wall of the stirring barrel.

[0006] Furthermore, the bottom of the mixing barrel is conical, the second liquid injection pipe is located on the side of the mixing barrel surface close to the inclined direction, and a valve is fixedly installed on the surface of the second liquid injection pipe.

[0007] Furthermore, the inner wall of the injection channel is in contact with the upper surface of the blanking plate, and the injection channel is also inclined.

[0008] Furthermore, the mounting assembly includes a mounting plate, a mounting frame is fixedly mounted on the top of the mounting plate, and the mixing barrel is fixedly mounted on the inner wall of the mounting frame.

[0009] Furthermore, a fixing frame is fixedly installed on the surface of the mounting frame, and the driving assembly includes a motor fixedly installed on the top of the fixing frame, the rotating rod is fixed to the output end of the motor, and a connecting rod is rotatably installed on the bottom of the fixing frame, a gear is fixedly installed on the bottom of the connecting rod, and a gear ring meshing with the gear is fixedly installed on the outer wall of the movable cover, and pulleys are fixedly installed on the surfaces of the connecting rod and the rotating rod, and the inner walls of the two pulleys are transmission-connected with belts.

[0013] Compared with the prior art, the utility model provides a corn seed coating machine, which has the following beneficial effects:

[0014] 1. The corn seed coating machine adds the coating agent into the inner cavity through the provided inner cavity, the filter plate and a plurality of injection channels. The coating agent enters into the stirring barrel through the injection channel during the flow, thereby the coating agent can be evenly added into the stirring barrel. At the same time, the corn seeds are stirred by the stirring rod so that they can be mixed with the coating agent more evenly. Since the bottom of the stirring barrel is conical, the corn seeds located at the bottom of the inner side of the stirring barrel will flow toward the middle autonomously, thereby entering into the fixed cover, and then moved back to the upper inner side of the stirring barrel under the drive of the auger blades. Such a reciprocating cycle greatly improves the efficiency of mixing the corn seeds and the coating agent, and ensures the quality of corn seed coating in the later stage.

[0015] 2. The corn seed coating machine has a second liquid injection pipe. When the number of corn seeds is small, the coating agent can be injected through the second liquid injection pipe, which can reduce the waste of the coating agent and greatly improve the practicality of the device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 2 and Figure 3 as well as Figure 5An auger assembly for moving the corn at the bottom is also provided inside the fixed cover 2, wherein the auger assembly includes a rotating rod 6, on the surface of which an auger blade 7 is fixedly installed, an inner cavity 8 is also provided inside the mixing barrel 1, a blanking plate 9 is fixedly installed on the inner wall of the inner cavity 8, the surface of the blanking plate 9 is inclined and spirally wound inside the inner cavity 8, a plurality of injection channels 10 connected to the inner cavity 8 are also provided on the inner wall of the mixing barrel 1, a filter plate 11 is fixedly installed on the inner wall of the injection channel 10, a first injection pipe 12 is fixedly installed on the top of the mixing barrel 1, and a second injection pipe 13 is fixedly installed on the outer wall of the mixing barrel 1.

[0026] The filter plate 11 is provided to prevent corn seeds from entering the injection channel 10 and affecting the flow of the coating agent.

[0027] In addition, by providing the second injection pipe 13, when the number of corn seeds is small, the coating agent can be injected through the second injection pipe 13, that is, the waste of the coating agent can be reduced, and the practicality of the device is greatly improved.

[0028] The coating agent is added into the inner cavity 8. During the flow, the coating agent enters into the mixing barrel 1 through the injection channel 10, so that the coating agent can be evenly added into the mixing barrel 1. At the same time, the corn seeds are stirred by the stirring rod 24 so that they can be mixed with the coating agent more evenly.

[0029] At the same time, the bottom of the mixing barrel 1 is conical, that is, the corn seeds located at the bottom of the inner side of the mixing barrel 1 will flow toward the middle autonomously, thereby entering the interior of the fixed cover 2, and then moved back to the upper inner side of the mixing barrel 1 under the drive of the auger blades 7, and so on. The reciprocating cycle greatly improves the efficiency of mixing the corn seeds and the coating agent, and ensures the quality of the corn seed coating in the later stage.

[0030] It is worth noting that the bottom of the mixing barrel 1 is conical, and the second injection pipe 13 is located on the side of the surface of the mixing barrel 1 close to the inclined direction. A valve is fixedly installed on the surface of the second injection pipe 13. The inner wall of the injection channel 10 is in contact with the upper surface of the discharge plate 9. The injection channel 10 is also inclined to facilitate the coating agent to flow into the interior of the mixing barrel 1.

[0031] In this embodiment, the mounting assembly includes a mounting plate 14 , a mounting frame 15 is fixedly mounted on the top of the mounting plate 14 , and the mixing barrel 1 is fixedly mounted on the inner wall of the mounting frame 15 .

[0032] In this embodiment, a fixing frame 4 is also fixedly mounted on the surface of the mounting frame 15, and a driving component for driving the movable cover 3 and the auger blade 7 to rotate is also provided on the surface of the mixing barrel 1. The driving component includes a motor 5 fixedly mounted on the top of the fixing frame 4, and a rotating rod 6 is fixed to the output end of the motor 5.

[0033] Among them, a connecting rod 17 is also rotatably installed at the bottom of the fixed frame 4, a gear 18 is fixedly installed at the bottom of the connecting rod 17, a gear ring 19 meshing with the gear 18 is fixedly installed on the outer wall of the movable cover 3, and pulleys 21 are fixedly installed on the surfaces of the connecting rod 17 and the rotating rod 6, and the inner walls of the two pulleys 21 are transmission-connected with belts 22.

[0034] By means of the belt pulley 21 and the belt 22 , the motor 5 can drive the connecting rod 17 to rotate synchronously when driving the rotating rod 6 to rotate.

[0035] In addition, through the provision of the gear 18 and the gear ring 19 , the connecting rod 17 will drive the gear 18 to rotate when rotating, and then the movable cover 3 will rotate through the gear ring 19 , thereby realizing the rotation of the stirring rod 24 .

[0036] See also Figure 6 In this embodiment, a limiting groove is provided on the surface of the fixed cover 2, and a limiting slider 20 located inside the limiting groove is fixedly installed on the inner wall of the movable cover 3. An opening 23 is provided at the bottom of the fixed cover 2, and the opening 23 is used for corn seeds at the bottom to enter the interior of the fixed cover 2.

[0037] The limiting sliding block 20 and the limiting sliding groove are provided to facilitate the installation of the movable cover 3 while ensuring its smooth rotation.

[0038] In this embodiment, a discharge pipe 16 is fixedly mounted on the bottom of the mixing barrel 1 , and a sealing piece is threadedly mounted on the inner wall of the discharge pipe 16 .

[0039] Among them, after the coating is completed, the sealing sheet can be removed to facilitate the discharge of the corn seeds.

[0040] When the present embodiment is in use, corn seeds are poured into the mixing barrel 1, and the motor 5 is started to drive the rotating rod 6 to rotate. When the rotating rod 6 rotates, it drives the connecting rod 17 to rotate through the pulley 21 and the belt 22, thereby rotating the gear 18. When the gear 18 rotates, it causes the movable cover 3 to rotate through the gear ring 19, thereby rotating the stirring rod 24. The coating agent is injected into the inner cavity 8 through the first injection pipe 12 or the second injection pipe 13. During the flow, the coating agent enters the mixing barrel 1 through the injection channel 10, thereby allowing the coating agent to be evenly added to the mixing barrel 1. At the same time, the corn seeds are stirred by the stirring rod 24, so that they can be mixed with the coating agent more evenly. Since the bottom of the mixing barrel 1 is conical, the corn seeds located at the bottom of the inner side of the mixing barrel 1 will flow toward the middle autonomously, thereby entering the fixed cover 2, and then moved back to the upper inner side of the mixing barrel 1 under the drive of the auger blade 7. Such a reciprocating cycle greatly improves the efficiency of mixing the corn seeds and the coating agent, and ensures the quality of corn seed coating in the later stage.
