Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural planting technology, and in particular to a seed coating device. Background Technology
[0002] Before planting agricultural seeds, seeds often need to be treated. Seed treatment refers to mixing seeds with pesticides or micronutrients to coat the seed surface evenly with a layer of pesticide or micronutrients. This is a key measure for preventing and controlling certain pests and diseases. Large-scale farms generally use large mixers for mixing, while small individual farmers use traditional mixers that are smaller and usually only use a single mixing wheel. The position of the mixing wheel is fixed, and the mixing is done by simply rotating the spiral blades up and down. This often requires a long mixing time, which is inefficient for small individual farmers and easily leads to uneven mixing. At the same time, the rotation of the existing mixing blades can directly beat the seeds, which may break the seeds and affect the effectiveness of seed treatment. Utility Model Content

[0016] 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.
[0017] like Figures 1 to 4The seed mixing device shown includes a mixing tank 5, a mixing assembly, and a support platform 1. The support platform 1 includes a tabletop and supporting legs, or lockable casters may be provided below the supporting legs; these are conventional structures and will not be described in detail. The mixing tank 5 is cylindrical and fixedly mounted on the tabletop of the support platform 1. The bottom of the mixing tank 5 passes through the tabletop of the support platform 1. The bottom of the mixing tank 5 has a funnel-shaped discharge port 51. The mixing assembly includes a fixing frame, a rotating disc 7, and a spiral mixing tube 6. The fixing frame includes a supporting vertical rod 2 and a mounting horizontal plate 3. The supporting vertical rod 2 is fixedly mounted on the tabletop of the support platform 1 and located on the side of the mixing tank 5. The mounting horizontal plate 3 is located at the top of the supporting vertical rod 2. A cylinder is fixedly mounted in the middle of the mounting horizontal plate 3. Mounting box 4; the rotating disk 7 is rotatably mounted inside the cylindrical mounting box 4; the rotating disk 7 has a rotating shaft 71 at its center; the rotating shaft 71 extends from the top surface of the cylindrical mounting box 4 and is connected to the output end of the first control motor 72; the rotating disk 7 has an eccentrically set connecting post 62 on its bottom surface; the cylindrical mounting box 4 has a limiting hole 41 at its bottom; a second control motor 63 is fixedly mounted on the connecting post 62; the spiral stirring tube 6 has a mounting post 61 at its top; the mounting post 61 is connected to the output end of the second control motor 63; the spiral stirring tube 6 is a stainless steel cylindrical tube with a smooth surface in a spiral shape. Note the eccentric distance of the connecting post to ensure that the spiral stirring tube 6 will not touch the inner wall of the stirring tank 5 when it makes a circular motion.
[0018] In use, place the mounting plate 3 flat, put the spiral stirring tube 6 into the mixing tank 5, pour the seeds and pesticides into the mixing tank 5, and turn on the first control motor 72 and the second control motor 63. Due to the eccentric setting of the connecting column 62, the spiral stirring tube 6 will move in a circular motion in the mixing tank 5 to stir the seeds once. At the same time, when the second control motor 63 rotates, it drives the mounting column 61 and the spiral stirring tube 6 to rotate synchronously to mix the seeds a second time. Using two mixing methods effectively improves the mixing efficiency and ensures the uniformity of mixing. The spiral stirring tube with a smooth surface reduces the destructive force on the seed surface during rotation and mixing, ensuring the integrity of the seeds and improving the seed cultivation rate. If seeds splash out during the mixing process, the seed content in the mixing tank 5 can be appropriately reduced. In specific use, it is necessary to control the speed of the first motor so that the speed of the rotating disc 7 is relatively slow, while the speed of the spiral stirring tube 6 can be increased.
[0019] The bottom of the mixing tank 5 is provided with a pull-out baffle plate 52. The baffle plate 52 is inserted into the mixing tank 5 from the side of the support platform 1. An insertion groove can be provided on the side of the support platform 1, and an insertion groove can also be provided at the corresponding position of the mixing tank 5. The baffle plate 52 is inserted from the side of the support platform 1 until it blocks the bottom of the mixing tank 5. After the mixing is completed, the baffle plate 52 is pulled out, and the mixed seeds will flow out from the bottom outlet.
[0020] The first control motor 72 is fixedly installed on the outside of the top surface of the cylindrical mounting box 4; the cylindrical mounting box 4 is located directly above the mixing tank 5, and the centers of the cylindrical mounting box 4 and the mixing tank 7 are located on the same vertical line.
[0021] A limiting plate 42 exists between the bottom of the side wall of the cylindrical mounting box 4 and the limiting hole 41; the diameter of the limiting hole 41 is not less than the distance from the connecting column 62 to the center of the rotating disk 7. The limiting hole 41 is used to provide running space for the connecting column 62 when the rotating disk 7 rotates. The eccentric point of the connecting column 62 will leave a distance from the edge of the rotating disk 7. This distance is the width of the limiting plate 42. The rotating disk 7 can be locked into the cylindrical mounting box 4 by the limiting plate 42.
[0022] The mounting horizontal plate 3 and the supporting vertical rod 2 are rotatably connected by a damping shaft 21, which can rotate and lift the mounting horizontal plate 3, improving the convenience of operation. It is a conventional adjustable resistance rotation damping.
[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
