Description

Technical Field

[0001] The utility model relates to the technical field of shelling equipment, in particular to a peanut shelling machine. Background Technique

[0002] Peanut processing includes a series of processes such as shelling and separating the shell and grains. If it is manually operated, it is not only time-consuming and laborious, but also has low efficiency. Therefore, in the market, a special peanut shelling machine has also been designed for this purpose. For example, a peanut shelling machine with the publication number CN205624332U uses a crushing roller to initially squeeze the peanuts, causing the peanuts to be damaged. Then the peanuts enter between the conveyor belts. The speeds of the conveyor belts are different and they rub the peanuts, and the peanut grains are rubbed out, and the shell-grain separation is realized on the first vibrating screen.

[0003] This kind of peanut shelling machine realizes mechanized production, but it still has many defects. For example, during the process of the conveyor belt rubbing the peanuts, the broken peanut shells are easily scratched on the peanut material under the action of the conveyor belt, causing the peanut skins to be damaged and affecting the appearance of the product.

[0004] Based on this, the utility model aims to provide a peanut shelling machine to minimize the damage to peanuts during the processing process. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology, the utility model provides a peanut shelling machine, which is provided with a striking structure under the extrusion roller. After the peanut shells are squeezed and broken by the extrusion roller, they fall into the striking structure. The striking structure uses its own rotation to make the cracked peanuts collide between the second baffle and the striking shaft to realize the shell-grain separation. This separation method is not easy to cause damage to the peanut grains.

[0006] To achieve the above object, the utility model provides the following technical solutions:

[0007] A peanut shelling machine includes a support frame, on which a vibrating screen is provided. Above the vibrating screen on the support frame, a machine case is provided. At the top of the machine case, a feeding box is provided. At the top of the feeding box, a feeding hopper is provided. At the bottom of the machine case, a discharge port is provided. Inside the machine case, a set of extrusion rollers is provided. This set of extrusion rollers includes a rubber roller and a metal roller. The surface of the metal roller is provided with evenly distributed holes; a striking structure is provided on the support frame, and the striking structure is located below the discharge port of the machine case. The striking structure includes a rotating shaft, on which three turntables are successively arranged along the axial direction. A number of striking shafts are fixed on the turntables at both ends, and each striking shaft passes through the middle turntable; a driving motor is provided on the outer wall of the machine case, and the driving motor is simultaneously drivingly connected to the rubber roller, the metal roller and the striking structure.

[0008] In the present utility model, both ends of the rubber roller and the metal roller are respectively installed on the machine case through bearing seats. Among them, the bearing seat of the metal roller is fixedly installed on the machine case, the bearing seat of the rubber roller is slidably installed on the machine case, an adjusting screw is provided between the bearing seat of the metal roller and the bearing seat of the rubber roller, and both ends of the adjusting screw are respectively screwed and connected with the bearing seat of the metal roller and the bearing seat of the rubber roller.

[0009] In the present utility model, a feeding roller is provided above the extrusion roller in the feeding box, the feeding roller is located between the two extrusion rollers, and the feeding roller is connected with the metal roller through a synchronous belt.

[0010] In the present utility model, guide plates are respectively provided on both sides of the feeding roller in the feeding box, the top ends of the guide plates are installed on the inner side wall of the top of the feeding box, and the bottom ends of the guide plates incline towards the feeding roller side.

[0011] In the present utility model, first baffles are respectively provided at both axial ends of the metal roller on the machine case, and both first baffles are located above the metal roller.

[0012] In the present utility model, second baffles are respectively provided below the rubber roller and the metal roller on the machine case, and the lower segments of the two second baffles are respectively located on both sides of the hitting structure.

[0013] In the present utility model, the hitting structure includes several groups of hitting shaft groups, each group of hitting shaft groups is composed of several hitting shafts, and the hitting shafts of each hitting shaft group are distributed along the radial direction of the turntable. The distance between the hitting shafts in each hitting shaft group is not greater than the length of the peanut grain diameter.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, a group of extrusion rollers are used to initially crush the peanuts. One of the extrusion rollers in this group is a roller made of rubber material, and the other is a roller made of metal material, and holes are evenly distributed on the surface of the metal roller. The combined use of these two rollers made of different materials can, on the one hand, fully extrude the peanuts, and on the other hand, prevent extrusion damage caused by excessive extrusion.

[0016] 2. In the present utility model, the peanuts after being initially crushed enter the hitting structure, and the cracked peanuts collide between the second baffle and the hitting shaft by virtue of their own rotation. After the collision, the peanut shells will directly break and fall off, realizing the separation of the shell and the grains. During this separation process, the damaged peanut shells will not be mutually extruded and rubbed like the rubbing separation method, and it is not easy to cause damage to the peanut grains.

[0017] 3. In the present utility model, the bearing seat of the rubber roller is slidably installed on the machine case. According to peanuts of different sizes, the distance between the rubber roller and the metal roller can be adjusted by using the adjusting screw, so as to achieve crushing.
