Description

Technical Field

[0001] This utility model relates to the field of grain drug application technology, specifically a grain seed drug applicator. Background Technology

[0002] In the field of grain seed treatment, traditional drug applicators typically employ a mechanical structure that combines a mixing chamber with a screw conveyor. During operation, seeds and drugs are mixed through the feed inlet, and the mechanical force generated by the rotation of the screw conveyor achieves initial mixing, causing the drug to form a coating layer on the seed surface.

[0003] The main drawback of existing technologies is the insufficient contact efficiency between the drug and the seeds. On the one hand, spraying at a fixed location can easily lead to excessively high or low local drug concentrations, especially when treating large batches of seeds, where it is difficult to balance the stirring time and the uniformity of mixing. On the other hand, the manual pouring of drugs is significantly affected by human factors, resulting in differences in treatment quality between different batches. This unevenness not only reduces the protective effect of the seed coating agent, but may also affect the seed germination rate due to excessive drug residues, increasing subsequent screening costs. Utility Model Content

[0004] The purpose of this invention is to provide a seed medicine applicator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grain seed drug applicator, comprising a support, a mixing chamber fixedly mounted on the support, a motor fixedly mounted on one side of the support, a first pulley fixedly connected to the output end of the motor, an auger rotatably connected to the center of the mixing chamber, and a second pulley fixedly mounted at the lower end of the auger penetrating the mixing chamber; the first pulley and the second pulley are together fitted with a belt.

[0006] The upper end of the mixing chamber is fixedly connected to symmetrically arranged guide rods, a support plate is fixedly installed on one side of the upper end of the mixing chamber, a first partition is fixedly connected to one side of the support plate, and a spraying component is provided at the upper end of the auger;

[0007] The spraying assembly includes a reciprocating screw, which is fixedly connected to the upper end of the auger. A slider is threaded onto the outer wall of the reciprocating screw, and a transmission rod is fixedly connected to the slider. A second partition is fixedly connected to the transmission rod, and a baffle is fixedly connected to the upper end of the second partition. A baffle is fixedly connected to the lower end of the second partition, and a sealing plate is fixedly connected to the upper end of the baffle. Two symmetrically arranged limiting plates are fixedly connected to both sides of the baffle, and the two limiting plates are slidably connected to the guide rod.

[0008] Preferably, the diameter of the first partition cylinder is larger than the diameter of the second partition cylinder, and the first partition cylinder is sleeved outside the second partition cylinder.

[0009] Preferably, the baffle is annular and the cross-section of the baffle is designed with an L-shape.

[0010] Preferably, the sealing plate is made of rubber, and the gap between the sealing plate and the first and second partition cylinders corresponds to that between the sealing plate and the first and second partition cylinders.

[0011] Preferably, the baffle is designed with a conical structure and the surface of the baffle is smoothly transitioned.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by combining annular spraying with spiral stirring, when the seeds are conveyed upward under the push of the auger, the second partition cylinder driven by the reciprocating screw moves up and down along the guide rod, so that the medicine is continuously and evenly sprayed on the surface of the moving seeds through the annular gap, ensuring that each seed is in full contact with the medicine during the spiral ascent, and finally forming a uniform thickness of medicine film layer, which significantly improves the consistency and effectiveness of seed treatment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The present invention provides the following technical solution:

[0020] Example 1: A grain seed drug applicator includes a support 1, a mixing chamber 2 fixedly installed on the support 1, a motor 3 fixedly installed on one side of the support 1, a first pulley 4 fixedly connected to the output end of the motor 3, an auger 5 rotatably connected to the center of the mixing chamber 2, the lower end of the auger 5 passing through the mixing chamber 2 and fixedly installed with a second pulley 6, and a belt 7 being fitted together with the first pulley 4 and the second pulley 6.

[0021] When using, put the seeds into the mixing chamber 2, start the motor 3, the motor 3 drives the belt 7 to rotate through the first pulley 4, the belt 7 drives the second pulley 6 to rotate, the second pulley 6 drives the auger 5 to rotate, the rotating auger 5 then transports and spreads the seeds from the bottom of the mixing chamber 2 to the top, gradually spreading them. At this time, the medicine is slowly poured in a ring shape by hand. As it is transported and spread, the medicine can be evenly applied to the surface of the seeds.

[0022] Example 2: Based on Example 1, this example also includes: a guide rod 8 symmetrically arranged is fixedly connected to the upper end of the mixing chamber 2, a support plate 9 is fixedly installed on one side of the upper end of the mixing chamber 2, a first partition cylinder 10 is fixedly connected to one side of the support plate 9, and a spraying component is provided at the upper end of the auger 5;

[0023] The spraying assembly includes a reciprocating screw 11, which is fixedly connected to the upper end of the auger 5. A slider 12 is threadedly connected to the outer wall of the reciprocating screw 11. A transmission rod 13 is fixedly connected to the slider 12. A second partition 14 is fixedly connected to the transmission rod 13. A baffle 15 is fixedly connected to the upper end of the second partition 14. A baffle 16 is fixedly connected to the lower end of the second partition 14. A sealing plate 17 is fixedly connected to the upper end of the baffle 16. Two symmetrically arranged limiting plates 18 are fixedly connected to both sides of the baffle 16. The two limiting plates 18 are slidably connected to the guide rod 8 respectively.

[0024] The diameter of the first partition 10 is larger than that of the second partition 14. The first partition 10 is sleeved outside the second partition 14. The baffle 16 is annular and has an L-shaped cross-section. The sealing plate 17 is made of rubber and corresponds to the gap between the sealing plate 17 and the first partition 10 and the second partition 14. The baffle 15 has a conical structure and a smooth surface transition.

[0025] In use, the liquid is poured onto the upper end of the baffle plate 15 in one go. The conical baffle plate 15 diverts the liquid, which flows into the gap between the first partition 10 and the second partition 14. As the auger 5 rotates, it drives the reciprocating screw 11 to rotate. The reciprocating screw 11 then drives the slider 12 to move up and down. The slider 12 then drives the second partition 14 to move up and down through the transmission rod 13. The moving second partition 14 then drives the baffle 16 and the sealing plate 17 to move up and down. The guide rod 8 then limits the baffle 16 through the limiting plate 18. When the sealing plate 17 seals the gap between the first partition 10 and the second partition 14, the liquid is difficult to flow out. When it leaves the sealed state, the liquid falls in a ring onto the surface of the seed being transported and diffused, making the liquid pouring more uniform and continuous, effectively avoiding the unevenness caused by manual pouring.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
