Abstract
Description
Technical Field
[0001] This utility model relates to the field of corn planting technology, specifically to a seed dressing device for corn planting. Background Technology
[0002] Corn seed dressing is a technique that uses mechanical or manual methods to evenly coat the surface of seeds with substances such as seed dressing agents, pesticides, fertilizers, and growth regulators, forming a protective layer or functional coating. The seed dressing agents containing trace elements or plant hormones in the functional coating can promote root development and enhance the seeds' resistance to cold and drought. They also contain insecticides and fungicides to prevent underground pests and seedling diseases. Slow-release seed dressing fertilizers can provide nutrients in a targeted manner in the early stages of seed germination, improving fertilizer utilization.
[0003] Existing seed mixing devices typically use vertical mixing, with blades installed on the central shaft of the mixing tank. The rotation generates vortex mixing. While the rapid rotation improves seed fluidity, it also leads to a very high seed breakage rate and makes it difficult to discharge the accumulated material at the bottom. Utility Model Content
[0004] In order to solve the technical problems of existing seed mixing devices, which improve seed fluidity through rapid rotation but also lead to a very high seed breakage rate and difficulty in draining the accumulated material at the bottom, this invention provides a seed mixing device for corn planting.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a seed mixing device for corn planting, comprising: a seed mixing box (1), the upper part of which is a semi-circular curved plate, a main shaft (2) rotatably connected to the side wall at the center of the semi-circular curved plate of the seed mixing box (1), a core roller (3) connected to the main shaft (2) inside the seed mixing box (1), blades (4) evenly distributed on the circumference of the core roller (3), the edges of the blades (4) contacting the inner wall of the semi-circular curved plate of the seed mixing box (1), a bearing frame (5) connected between two blades (4), and a leaf-picking shaft (6) rotatably connected inside the bearing frame (5). The upper circumference is evenly connected with blades (7). The rotation path of the outermost end of the blade (7) coincides with the circumferential surface where the two blades (4) intersect. The outer end of the blade shaft (6) is connected with a gear (8). The gear (8) meshes with the toothed ring (9). The toothed ring (9) is connected to the inner wall of the seed mixing box (1). The bearing frame (5) can fasten the toothed ring (9) and the toothed ring (9) in the space formed with the inner wall of the seed mixing box (1). The top of the semi-circular curved plate of the seed mixing box (1) is connected to the spraying mechanism (11). The circumferential surface of the seed mixing box (1) that rotates along the blade (4) toward the spraying mechanism (11) is connected to the hopper (12).
[0006] Preferably, the blade (4) has an annular groove (10) and the toothed ring (9) is located in the annular groove (10).
[0007] Preferably, the lower half of the seed mixing box (1) is connected to the seed discharge hopper (13).
[0008] Preferably, a guide block (14) is connected to the upper part of the bearing frame (5), and the guide block (14) is inclined from high to low towards the blade (7).
[0009] Preferably, the spraying mechanism (11) includes an injection pipe (111), the lower end of which is connected to the liquid distribution box (112). The liquid distribution box (112) is located inside the spraying shell (113). The spraying shell (113) is connected to the top of the semi-circular curved plate of the seed mixing box (1). Multiple nozzles are evenly distributed on the lower part of the liquid distribution box (112).
[0010] Compared with the prior art, the beneficial effects of this utility model are: The seeds are injected into the leaf space through the hopper, and then the leaves move the seeds to the bottom of the spraying mechanism for spraying. During the rotation of the leaves, the leaves rotate and agitate the seeds in the leaf space, so that the seeds can flow and be evenly sprayed by the spraying mechanism. Finally, the leaves rotate to the bottom and discharge the mixed seeds. This ensures a low seed breakage rate and more even seed mixing. Attached Figure Description

[0013] 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.
[0014] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.
[0015] The present invention will now be described in detail with reference to the accompanying drawings.
[0016] The following is in conjunction with the appendix Figure 1-4 This embodiment describes a seed-coating device for corn planting, comprising: a seed-coating box 1, the upper part of which is a semi-circular curved plate; a main shaft 2 is rotatably connected to the side wall at the center of the semi-circular curved plate of the seed-coating box 1; a core roller 3 is connected to the main shaft 2 inside the seed-coating box 1; blades 4 are evenly distributed on the circumference of the core roller 3; the edges of the blades 4 contact the inner wall of the semi-circular curved plate of the seed-coating box 1; a bearing frame 5 is connected between two blades 4; a leaf-picking shaft 6 is rotatably connected inside the bearing frame 5; and a leaf-picking shaft 6 is evenly distributed on its circumference. A leaf 7 is connected, and the rotation path of the outermost end of the leaf 7 coincides with the circumferential surface where the two blades 4 intersect. A gear 8 is connected to the outer end of the leaf shaft 6, and the gear 8 meshes with the toothed ring 9. The toothed ring 9 is connected to the inner wall of the seed mixing box 1. The bearing frame 5 can fasten the toothed ring 9 and the toothed ring 9 in the space formed with the inner wall of the seed mixing box 1. The top of the semi-circular curved plate of the seed mixing box 1 is connected to the spraying mechanism 11. A hopper 12 is connected to the circumferential surface of the seed mixing box 1 that rotates along the blades 4 toward the spraying mechanism 11.
[0017] When the main shaft 2 is powered on, it drives the core roller 3 and blades 4 to rotate. Seeds are injected into the space between two adjacent blades 4 through the hopper 12. Then, the blades 4 move the seeds to the lower part of the spraying mechanism 11 for spraying. During the rotation of the blades 4, the bearing frame 5 drives the leaf-pulling shaft 6 and gear 8 to rotate around the axis of the main shaft 2. The gear 8 rolls along the surface of the toothed ring 9, causing the leaf-pulling shaft 6 and the leaf 7 to rotate. Since the bearing frame 5 can engage the toothed ring 9 with the space formed by the inner wall of the seed mixing box 1, the falling seeds will not enter the meshing point of the gear 8 and the toothed ring 9 and be crushed. The rotating blades 7 stir the seeds in the space of the blades 4. When the space of the blades 4 rotates through the lower part of the spraying mechanism 11, the blades 7 rotate at least one revolution, so that the seeds can flow and be evenly sprayed by the spraying mechanism 11. Finally, the blades 4 rotate to the bottom and discharge the mixed seeds. This ensures a low breakage rate of seeds due to slow mixing and makes the mixing more uniform.
[0018] The blade 4 has an annular groove 10, and the toothed ring 9 is located inside the annular groove 10.
[0019] In this way, within the limited space of the seed mixing box 1, a scientific layout is achieved, leaving more space for seed mixing.
[0020] The lower half of the seed mixing box 1 is connected to the seed discharge hopper 13.
[0021] After being treated, the seeds slide down the inclined surface of the seed discharge hopper 13 for easy collection.
[0022] A guide block 14 is connected to the upper part of the bearing bracket 5. The guide block 14 is inclined from high to low towards the blade 7.
[0023] The guide block 14 prevents seeds from accumulating in the dead corner of the upper part of the bearing frame 5 during seed feeding, thus avoiding uneven seed mixing.
[0024] The spraying mechanism 11 includes an injection pipe 111, the lower end of which is connected to a liquid distribution box 112. The liquid distribution box 112 is located inside the spraying shell 113. The spraying shell 113 is connected to the top of the semi-circular curved plate of the seed mixing box 1. Multiple nozzles are evenly distributed on the lower part of the liquid distribution box 112.
[0025] The seed dressing agent is injected through the injection pipe 111 and then distributed through the distribution box 112 to different nozzles for downward spraying, ensuring uniform spray coverage.
