Peanut seed sheller

Abstract

The invention discloses a peanut seed sheller, and belongs to the technical field of peanut seed shellers. The peanut seed sheller comprises a rack, a feed hopper which is arranged on the rack, a peanut shelling device, a kernel / shell winnowing and separation device, a driving motor and a transmission device; the outer wall of the feed hopper is hinged with the rack; the peanut shelling device isarranged below the feed hopper through the rack and comprises a shelling structure, a replication structure and a peanut shell / kernel uniform distribution structure; the shelling structure comprises aroller and an arc-shaped screen body; the roller comprises a roller shaft and a plurality of rubbing columns; each rubbing column comprises a column core and a nylon sleeve; the inner holes of the nylon sleeves are connected with the column cores in a sliding matching manner; a plurality of grooves are radially formed in the column surfaces of the nylon sleeves; the grooves are uniformly arrangedalong the circumferences of the column surfaces of the nylon sleeves; and the replication structure comprises a cross joint type universal coupling and a short shaft which is connected with the crossjoint type universal coupling end to end. The peanut seed sheller has the advantages of being convenient to clean the sundries of arc-shaped screens, causing less damages to the peanut seed kernels and the skins of the peanut seed kernels in the shelling process, and being high in efficiency of obtaining high-quality peanut seeds.

Description

Technical field [0001] The invention relates to the technical field of a peanut seed sheller. 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 for peanut seed dehulling. At present, peanut seed dehulling is mainly artificial. Peanut shelling gap between the shelling drum of the drum-type shelling structure of the peanut shelling machine and the curved screen 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, coupled with the rubbing action between the peanut pods, separate the peanut kernels and the shells of the pods, and the peanut kernels and peanut shells fall from the gap between the curved screen bars. The following disadvantages exist: 1. The rotation of the ...

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
