Two-stage shell-breaking type peanut sheller

Abstract

The invention discloses a two-stage shell-breaking type peanut sheller. The sheller comprises a peanut shell-breaking mechanism, a winnowing mechanism and a screening mechanism, wherein the peanut shell-breaking mechanism comprises a primary shell-breaking mechanism and a secondary shell-breaking mechanism; and the screening mechanism is provided with an un-broken peanut delivery mechanism. The sheller can ensure completeness of big peanut kernels and a shell-breaking separation rate being 100 percent, does not need to manually shell the un-broken peanuts so as to achieve the aim of saving time and labor, and is especially suitable for shelling and separating operation of seed peanuts.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a two-stage shell-cracking peanut sheller. Background technique [0002] With the development of social economy, more and more peanuts are planted as the main economic crop, and the workload of separating peanut shells is also increasing. Due to low cost and high efficiency, the use of various small peanut shellers is becoming more and more common. The peanut sheller mainly includes a shell breaking mechanism and a shell separation mechanism. The traditional peanut shell breaking mechanism mostly includes a shell, a squirrel cage type shell breaking roller and a grid. Through the rotation of the shell breaking roller and the impact with the grid The function realizes the crushing of peanut shells. The main defect of this structure is that: due to the different sizes of peanuts, the gap between the shell breaking roller and the grid is slightly larger, so the shel...

Problems solved by technology

The main defect of this structure is that: due to the different sizes of peanuts, the gap between the shell breaking roller and the grid is slightly larger, so the shells of peanuts with smaller individuals cannot be broken, and need to be sorted out by hand to shell, or The gap between the shell breaking roller and the grid is adjusted and crushed again, which is time-consuming and labor-intensive, which seriously affects the peeling efficiency; if the gap between the shell breaking roller and the grid is small, the peanut seeds are often crushed, especially Larger fine grains are easier to crush and cannot be used in peanut shelling

However, in this structure, only a row of protrusions on the upright rubber plate cooperate with each row of protrusions arranged in the axial direction of the rubber roller to implement peeling, and the elastic deformation of the rubber protrusions is relatively large, and its peeling efficiency is low. Squeeze, the pressure on fruit bodies of different sizes is different, the pressure on large fruit bodies is high, and the pressure on small fruit bodies is small, and the breaking rate will definitely be affected
