Embodiment Construction

[0017] Such as figure 1 As shown, a flexible differential corn thresher includes a frame 10 placed on the ground, a threshing chamber 3 fixed on the frame 10, a feeding hopper 1 arranged at the upper part of the input end of the threshing chamber 3, and a threshing chamber 3 The end of the output end and is used to discharge the core bucket 5 of the corn cob, and the sieve plate 8 arranged inside the core bucket 5 for separating the corn kernels and the corn cob. The threshing chamber 3 is provided with a threshing machine driven by a motor to rotate Cylinder 6 and the annular concave plate 7 that is located at the periphery of threshing cylinder 6, the two ends of annular concave plate 7 are fixed on the threshing chamber 3, as figure 2 As shown, the annular concave plate 7 is wrapped around the periphery of the threshing cylinder 6 at 270°, and there is a certain gap between the threshing cylinder 6 and the annular concave plate 7. To separate the corn kernels from the cor...

Abstract

A flexible differential corn threshing machine comprises a machine frame, a threshing chamber, a feeding hopper, a cob discharging hopper and a lower sliding plate arranged on the machine frame. A threshing cylinder and an annular concave plate arranged on the periphery of the threshing cylinder are arranged inside the threshing chamber. The upper portion of the annular concave plate is provided with an opening extending in the axial direction. A guiding line is arranged on the inner wall of the upper portion of the threshing chamber. A plurality of rows of spike teeth are evenly arranged on the peripheral face of the threshing cylinder at intervals in the axial direction. Each row of spike teeth are arranged in a staggered mode so as to be distributed in the spiral direction consistent with the spiral direction of the guiding line along the peripheral face of the threshing cylinder. According to the set height of the spike teeth, corn ears can be extruded between the spike teeth and the annular concave plate when pushed to move forwards, and therefore threshing is achieved. Kernels obtained through threshing are discharged through concave plate holes formed in the annular concave plate. The peripheral face of the threshing cylinder and the spike teeth are sleeved with rubber sleeves. According to the flexible differential corn threshing machine, repeated threshing of the corn ears is achieved, the ears are abraded through the spike teeth and the annular concave plate, differential threshing is formed, the threshing efficiency is improved, and the corn kernel damage rate is reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a flexible differential corn thresher. Background technique [0002] Corn is one of the three major food crops in the world, and my country is the main corn producing country in the world. Seed corn threshing is a key link in the harvesting work, which determines the degree of damage of seed corn and is a key link to ensure a high yield of corn. At present, the traditional corn thresher designed with the striking principle has a relatively high breakage rate of corn kernels, and it is difficult to keep the corncob intact, and it is difficult to completely thresh the kernels at the tip of the corn ear. The damage of seed corn affects the short-term and long-term storage of corn kernels. The damaged seed corn has a low germination rate, is prone to mold, insects, and is easy to break, and reduces its market value and export value. Threshing operation is also a heavy labor, t...
