A grain receiving hopper structure for grain processing equipment

Abstract

This utility model discloses a grain receiving hopper structure for grain processing equipment, belonging to the technical field of grain processing equipment. It includes a grain receiving hopper body, a bottom plate on the outer side of the hopper body, a motor on the top of the bottom plate, a dust blowing mechanism on the outer side of the bottom plate, a feeding shaft on the motor's rotating shaft, an extension assembly at the bottom of the hopper body, and a baffle at the bottom of the extension assembly. The dust blowing mechanism, with a U-shaped frame fixing a connecting plate and a fan to one side of the top of the hopper body, allows the fan to blow away the flowing grain, separating the grain from the dust. Simultaneously, dust and a small portion of the grain are blown onto the housing. The inclined filter plate can block the grain, while dust enters the internal dust collection trough. A drawer box stores dust, which can be emptied when full. A protective plate prevents grain from entering the fan from above. By separating dust and grain through the fan, the accumulation of dust and husk within the hopper body can be reduced.

Description

Technical Field

[0001] This utility model belongs to the technical field of grain processing equipment, and specifically relates to a grain receiving hopper structure for grain processing equipment. Background Technology

[0002] A grain receiving hopper is a device used to collect and store grain. It is commonly used in the agricultural sector to receive crops harvested from farmland, such as grains, soybeans, and corn. As an important component of the grain processing process, the grain receiving hopper needs to be installed in a suitable location based on the specific equipment layout and process flow, and the installation quality must be ensured to guarantee the smooth operation of the grain processing. It ensures that the grain can enter the next process in an orderly and stable manner, avoiding production interruptions or reduced efficiency caused by grain scattering or piling up.

[0003] In existing grain processing equipment, the grain receiving hopper structure can avoid blockages caused by grain accumulation by rotating a connected shaft driven by a motor installed on one side of the grain receiving hopper body. However, during use, it cannot blow away dust and husks from the incoming grain, causing dust to accumulate in dead corners inside the grain receiving hopper body. Furthermore, the discharge height of the grain receiving hopper cannot be changed during use, affecting its practicality. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a grain receiving hopper structure for grain processing equipment, which features dust removal from the grain and the ability to adjust the discharge height.

[0014] 1. This utility model is equipped with a dust blowing mechanism. The U-shaped frame fixes the connecting plate and the fan to one side of the top of the grain receiving hopper body. When the fan is started, it can blow the flowing grain to separate the grain and dust. At the same time, the dust and a small part of the grain will be blown onto the box body. The filter plate is inclined to block the grain. At the same time, the dust enters the internal dust collection groove. The drawer box can store dust and shells. When it is full, it can be emptied. The protective plate can prevent the grain from entering the fan from the top. By separating the dust and grain by the fan, the accumulation of dust and shells in the grain receiving hopper body can be reduced.

[0015] 2. This utility model is equipped with an extension component. Grain flows in from the top of the grain receiving hopper body and flows out from the bottom. Ring 1 is fixed to the bottom of the grain receiving hopper body. Ring 2 can be inserted into Ring 1 from below, and then the U-shaped rod is pushed upward so that the top of the U-shaped rod is inserted into the hook, thereby fixing Ring 2 below Ring 1. The rubber column can limit the U-shaped rod in the hook and strengthen the connection. The sealing ring of Ring 2 is also inserted into the sealing groove of Ring 1 to enhance the sealing performance and prevent grain leakage. By connecting Ring 1 and Ring 2, and then connecting multiple Ring 2, the discharge height can be increased to adapt to different usage environments. Attached Figure Description
