Description

A kind of peanut shelling machine

technical field

The utility model relates to an agricultural machine, in particular to a peanut sheller used for shelling peanuts.

Background technique

Peanuts, also known as groundnuts, are known as "vegetable meat". The oil content is as high as 50%, the quality is good, and the smell is fragrant. In addition to being edible, peanuts are also used in printing and dyeing and papermaking industries; peanuts are also a traditional Chinese medicine, suitable for symptoms such as malnutrition, spleen and stomach disorders, cough, phlegm and asthma, and lack of milk. As an important economic crop, peanut has a wide planting area in my country. Therefore, the harvesting and shelling methods of peanuts are of great significance to the economic development of the growing areas.

The traditional peanut shelling method is manual shelling, which is inefficient and requires a lot of labor, which seriously affects economic benefits. In recent years, with the expansion of peanut planting area and the increase of peanut production, the application of peanut shelling machine has gradually increased, and it has gradually become a convenient machine to replace the manual shelling method. The production efficiency of the peanut sheller is 10 to 50 times that of manual shelling, but it cannot ensure the integrity of the peanuts after shelling like manual shelling. In the existing peanut shelling machines in our country, people use horizontal peanut shelling machines to shell peanut pods. The main components of the shelling machine are shelling drums and grid concave screens. The rotating body removes the peanut shells, and the broken peanuts and broken peanut shells are separated from the grid concave screen, and then the peanut shells are blown out from the miscellaneous discharge port by the air flow of the fan, and the peanuts flow onto the inclined vibrating screen Filtered out. This kind of peanut shelling machine has certain disadvantages: (1) It is easy to cause damage to peanuts during the shelling process, and the crushing rate is high, which affects economic benefits; (2) The shelling roller is an integral structure, once damaged, it needs to be replaced , high equipment maintenance costs; (3) The cleaning device adopts a single-layer vibrating screen, which has a poor separation effect on peanuts, shells and other impurities. Therefore, this peanut sheller can not meet the present stage to the requirement of peanut seed shelling.

(1) The shelling roller described in this utility model is a four-stage rubber groove type shelling roller, and the shelling roller includes a shelling roller shaft and four separate toothed rollers installed on the shelling roller shaft Body, when the shelling roller needs to be replaced due to wear and tear, only the worn toothed roller body needs to be replaced without replacing the entire roller body, so the replacement is convenient and the maintenance cost of the equipment is reduced; at the same time, the toothed roller of the shelling roller The material of the body is rubber. Therefore, while ensuring the hardness of the toothed roller body, the elasticity of the toothed roller body is increased, thereby reducing the damage of the peanut fruit caused by the excessive hardness of the metal material roller body, and reducing the damage. rate, improving economic benefits;

(2) The vibrating sieve described in the utility model adopts a double-layer vibrating sieve, the sieve hole diameter of the upper sieve plate is larger than the sieve hole diameter of the lower sieve plate, and the pore diameter of the upper sieve plate is larger than the particle size of peanut fruit, while the lower sieve plate The pore size of the sieve plate is smaller than the particle size of the peanut fruit, thus ensuring that the impurities larger than the peanut fruit are discharged from the miscellaneous outlet connected to the upper sieve plate, and the peanut fruits are discharged from the main seed outlet connected to the lower sieve plate; The peanuts on the upper sieve plate can be discharged through the secondary seed outlet; at the same time, the lower sieve plate can also perform secondary screening for impurities in the peanut fruit, which improves the separation effect of peanuts, shells and other impurities.
