Peanut shelling device for peanut seed shelling machine

Abstract

The invention discloses a peanut shelling device for a peanut seed shelling machine, and belongs to the technical field of peanut shelling machines. The peanut shelling device includes a shelling structure, a turning structure and an uniform distribution structure of peanut pods. The shelling structure includes a roller and an arc-shaped sieve body. The roller includes a roller shaft and a plurality of rubbing columns, each rubbing column includes a column core and a nylon sleeve. The inner hole of the nylon sleeve is slidably connected with the column core, and a plurality of grooves are provided radially on the cylindrical surface of the nylon sleeve, and each groove is evenly distributed along the circumferential direction of the cylindrical surface of the nylon sleeve. The turning structure includes a cross shaft universal coupling and a short shaft connected from end to end. The uniform distribution structure of peanut pods includes two spiral blades symmetrically arranged on theroller shaft. The rotation direction of the two spiral blades causes the peanut pods to be pushed from the middle to both ends, and the pitch of the two spiral blades gradually increases from the inner end to the outer end. The device has the advantages of being convenient for cleaning the debris of the arc-sieve, thereby causing less damage to the peanut seed kernel and the peanut seed red coat during the shelling process and obtaining high-quality peanut seeds with high efficiency.

Description

technical field [0001] The invention relates to the technical field of peanut shelling machines. Background technique [0002] If the red coat (seed coat) on the surface of peanut kernels is incomplete, it will directly affect the emergence rate and the growth of peanuts after emergence. Therefore, there are strict requirements on the shelling of peanut seeds. At present, shelling of peanut seeds is mainly based on manual shelling. The peanut shelling gap between the shelling drum and the curved screen of the drum shelling structure of the peanut shelling machine is the peanut shelling gap. Before the peanut shelling, the peanut shelling gap needs to be filled with peanut pods, and the peanuts are hit by the rubbing column of the drum. The pods, together with the rubbing action between the peanut pods, separate the peanut kernels from the pod shells, and the peanut kernels and peanut shells fall from the gap between the arc-shaped sieve bars, which has the following disadva...

Problems solved by technology

The peanut shelling gap between the shelling drum and the curved screen of the drum shelling structure of the peanut shelling machine is the peanut shelling gap. Before the peanut shelling, the peanut shelling gap needs to be filled with peanut pods, and the peanuts are hit by the rubbing column of the drum. The pods, together with the rubbing action between the peanut pods, separate the peanut kernels from the pod shells, and the peanut kernels and peanut shells fall from the gap between the arc-shaped sieve bars, which has the following disadvantages: 1. The rotation of the rubbing column affects the peanut shell Direct hard hitting will easily cause damage and fall off the fragile red coat on the surface of peanut kernels; 2. When the shelling work is over, first stop sending peanut pods to the shelling structure, and as the shells continue to separate from the arc The gap between the sieve bars falls down, and the peanut pods remaining in the peanut shelling gap are less and less, and finally the shelling work is stagnant due to the rubbing action of the shelling roller. The gap between the grid bars in the shape sieve, so that a part of the mixture of peanut pods, pod shells and peanut kernels will be blocked in the gaps of the peanut shelling grid bars, and the gaps of the grid bars will be blocked. Falling will increase the probability of contact between the peanut kernel and the rigid roller, making the seed coat fall off more seriously; 3. While transporting the peanut pods to the shelling structure, it is inevitable that stones and other massive debris will be mixed in and accumulated in the arc. In the sieve, during the movement, it will not only cause impact damage to the seed coat of peanut kernels, but also easily cause damage to the drum and curved sieve

[0003] Therefore, when the equipment is used again, it is necessary to remove the bearing seats on both sides of the shelling drum, and then remove the entire shelling drum to clean up the sundries on the curved screen. This operation process is complicated, time-consuming and laborious. Promptly clean up remaining mixture
