Description

Technical Field

[0001] This utility model relates to the field of seed dressing technology, specifically a wheat seed dressing device. Background Technology

[0002] In large-scale wheat cultivation, seed treatment with pesticides is a crucial pretreatment step for preventing seedling diseases and pests and ensuring healthy seedling growth. By uniformly mixing pesticides with seeds, an effective pesticide film can be formed on the seed surface, which can reduce the damage to seeds caused by pathogens in the soil and underground pests, and also reduce the amount of pesticides needed for later field spraying, thus meeting the requirements of green agricultural production.

[0003] In the prior art, CN217742208U discloses a seed coating device for wheat breeding, which includes a base. A mixing tank is fixedly installed on one side of the top surface of the base by several support rods. A feed hopper is provided on one side of the top surface of the mixing tank, and a discharge hopper is provided at the bottom of the outer periphery of the mixing tank. A first through hole is opened in the center of the top surface of the mixing tank. A rotating shaft is installed in the first through hole by a bearing. Several stirring rods are fixedly installed on the outer periphery of the rotating shaft, etc. Although the seeds can be stirred by stirring rods, because the mixing tank is a straight cylinder design and the stirring rods are vertical, most of the medicine will fall to the bottom of the mixing tank during stirring, and cannot effectively coat the seed surface to form a coating. Therefore, further optimization is needed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wheat seed pesticide mixing device, which solves the problems mentioned in the background art.

The stirring rod includes an upper support rod located in the upper cavity, a lower support rod located in the lower cavity, and a spiral blade located in the discharge pipe.

[0007] Preferably, the upper surface of the U-shaped base plate is provided with a rotatable support plate, and a detachable collection box is symmetrically provided on the upper surface of the support plate, the collection box being located below the horizontal plate.

[0008] Preferably, a motor is provided in the middle of the lower surface of the U-shaped plate base plate, and the output end of the motor passes through the base plate and is fixedly connected to the bottom of the support plate.

[0009] Preferably, the top of the mixing tank is provided with a drug inlet, and a rotatable auxiliary plate is provided above the drug inlet. The bottom of the auxiliary plate and the side wall of the mixing tank are provided with support bars. A vertical rod is fixedly connected to the bottom of the auxiliary plate.

[0012] This utility model has the following beneficial effects: This wheat seed coating device addresses the problems of pesticide sedimentation at the bottom and insufficient coating in existing cylindrical mixing tanks. The device achieves significant optimization through a layered mixing structure. The mixing tank is divided into an upper cavity, a through-hole, and a lower cavity. A stirring rod aligns with each cavity, creating a simultaneous mixing effect in both upper and lower zones. This reduces the likelihood of pesticide settling at the bottom of the mixing tank, minimizing uneven mixing caused by gravity stratification of seeds and pesticide. Furthermore, the design of the stirring rod extending to the discharge pipe not only mixes the seeds but also prevents seed blockage. This wheat seed pesticide mixing device has two pesticide storage cylinders on the auxiliary plate that can store different types of pesticides. When the motor is started, it can drive the support plate and the collection box on top of it to rotate. Since the vertical rod is fixed on the upper surface of the support plate, it drives the auxiliary plate and the pesticide storage cylinders on top of it to rotate synchronously. At this time, different pesticide storage cylinders and corresponding collection boxes can be switched, making it convenient to change different types of pesticides and collection containers. This wheat seed pesticide mixing device features a detachable collection box for easy transfer of the mixed pesticide, avoiding material spillage during the feeding process of traditional devices. The horizontal plate on the U-shaped plate can quickly control the start and stop of the discharge, and the support bars and fixing blocks limit the vertical rods to ensure the stability of the equipment operation.
