Technical Field
[0001] This utility model relates to the field of agricultural planting, and in particular to a seed dressing device for agricultural planting. Background Technology
[0002] An existing patent (publication number: CN219741190U) discloses a seed coating device for agricultural planting. It includes two symmetrical mixing supports, with a collection mechanism at the lower end of each support, a power mechanism at the right end of the right-hand support, and a mixing mechanism at the upper end of both supports. The collection mechanism collects the coated seed material, and the power mechanism provides the power for the coating. The collection mechanism includes a mounting base plate fixedly connected to the lower surface of the two mixing supports, with two symmetrical mounting holes at each end. However, this device, where "the mixing shaft drives the mixing mounting base and the mixing cylinder to rotate synchronously," relies on the mixing cylinder above the mixing supports to mix the seed material. During mixing, the seed material may stick to the inner wall of the mixing cylinder, causing uneven coating and affecting the yield of the finished product. Summary of the Invention
[0003] This invention addresses the aforementioned shortcomings of existing technologies by providing an agricultural seed mixing device. A gear motor at the front of the frame drives a gear to rotate, which in turn rotates a seed mixing cylinder for mixing. Simultaneously, a drive motor at the rear of the motor bracket drives a drive shaft to rotate, which in turn drives a scraper inside the seed mixing cylinder to remove seed material adhering to the inner wall. This prevents uneven mixing caused by seed material adhering to the inner wall, thereby increasing the yield of the finished product.
