Description

Technical Field

[0001] The utility model belongs to the technical field of peanut processing, in particular to a shelling device. Background Art

[0002] Peanuts have high nutritional value, rich in fat and protein, and are an important raw material for more than 100 kinds of food. They have many nutritional benefits, such as stabilizing blood sugar, maintaining heart health, reducing the risk of colon cancer and enhancing memory. In addition to being eaten, peanuts are also used in printing and dyeing and papermaking industries. At the same time, peanuts are also a traditional Chinese medicine, suitable for symptoms such as malnutrition, spleen and stomach disorders.

[0003] Peanuts need to be shelled after being harvested. The traditional way of shelling peanuts is to manually peel them, which is time-consuming and labor-intensive, with low work efficiency, high labor intensity and high labor costs.

[0004] There are devices for breaking peanut shells in the prior art. A Chinese utility model patent (publication number: CN209995304U) discloses a bionic peanut shelling machine, including a main support, a shelling mechanism is fixedly installed on one side of the top of the main support, a feed hopper is arranged on one side of the top of the shelling mechanism, a transmission box is fixedly installed on one side of the outer surface of the shelling mechanism, a screening mechanism is arranged on one side of the bottom of the shelling mechanism, a discharge port is arranged on the outer surface of the screening mechanism close to the transmission box, a first motor is fixedly installed on one side of the inner bottom of the transmission box, a first bevel gear is fixedly installed on one side of the output end of the first motor, and a second bevel gear is arranged on one side of the outer surface of the first bevel gear. The bionic peanut shelling machine described in the utility model can ensure that the overall device can not only shell the peanuts but also ensure the integrity of the peanuts after shelling during the peanut shelling process, improve the work efficiency of the users, and bring better prospects for use. However, its structure is relatively complex and the cost is relatively high for general farmers. In addition, the device cannot adjust the shell-breaking gap according to demand when breaking the shell. If the shell-breaking gap is too large, the peanut shell may not be effectively broken, resulting in reduced shell-breaking efficiency. On the contrary, if the gap is too small, the peanut shell may be over-broken, causing the peanut seeds to be damaged and reducing product quality. Utility Model Content
