Description

Threshing machine for agricultural production

Technical Field

The utility model relates to the field of agriculture, concretely relates to thresher for agricultural production.

Background

The thresher is a harvesting machine, which is a machine capable of separating crop seeds from stalks, and mainly relates to a grain crop harvesting machine. The thresher is of different types according to different grain materials. For example, the rice thresher is suitable for threshing rice; for threshing corn, a so-called "corn thresher" or the like is used. The thresher is commonly called a "thresher", and is the most common rice threshing machine. After the rice is harvested, the rice grains are separated from the stalks by the machine. The rice thresher is divided into two types, one type is driven by manpower, is called as a manpower rice thresher and is a semi-mechanized tool; the rice thresher is changed into power driving, so the rice thresher is called as a power rice thresher. The rice thresher greatly reduces the labor intensity of rice harvesting and improves the agricultural productivity at the same time.

The existing corn thresher adopts manual bare-handed pushing corn cobs into a threshing cylinder of the thresher. In this pushing manner, the worker needs to overcome the blocking force from the threshing cylinder to push the corn cobs, hold the corn cobs and prevent the corn cobs from rotating, which results in high labor intensity of the worker.

Disclosure of Invention

The utility model aims to provide a: provides a thresher for agricultural production, which solves the problem that the labor intensity of workers is higher because the existing corn thresher feeds materials by hands. The utility model discloses a thresher for agricultural production when the pay-off, has utilized lever principle to carry out the pay-off to need less external force can carry out the pay-off operation in making actual operation, reduced workman's intensity of labour, improved the convenience that corn thresher used.

The utility model adopts the technical scheme as follows:

a threshing machine for agricultural production comprises a threshing machine body, wherein the threshing machine body comprises a threshing cylinder, a workbench and a rotary driving mechanism, the workbench is provided with a discharge hole, the bottom of the threshing cylinder is rotatably connected with the workbench and is communicated with the discharge hole, the driving mechanism is fixed on the workbench and drives the threshing cylinder to rotate around the axis of the discharge hole, an auxiliary device is arranged on the workbench and comprises a stand column vertically arranged on the upper surface of the workbench, a lever with one end hinged with the top of the stand column and a pressing component arranged on the lever, the pressing component comprises a matching block, a handle rod and a pressing rod, a long round hole is arranged in the matching block, the long edge of the cross section of the long round hole is parallel to the axis of the stand column, the end, far away from the hinge joint, of the lever penetrates through the long round hole, the bottom end of the handle rod is connected with the upper surface of the matching block, and the axis of the pressing rod coincides, the top end of the pressure lever is connected with the lower surface of the matching block.

The utility model aims at a novel corn thresher. The traditional corn thresher is used for feeding materials on the side, the axis of a corn threshing cylinder is parallel to the horizontal plane, and the utility model is suitable for a thresher with the axis of the threshing cylinder vertical to the ground. The threshing cylinder is rotatably arranged on the workbench and is coaxial with the discharge hole, and the rotary driving mechanism drives the threshing cylinder to rotate.

When the corn is threshed, the small-diameter end of the corn is inserted into a threshing cylinder, the bottom of the pressure lever is contacted with the large-diameter end of the corn, then one hand holds the end of the lever far away from the hinge joint, and presses down the lever; the handle is held by the other hand, so that the matching block is prevented from moving in the radial direction of the threshing cylinder by the rotation of the lever, the matching block can only move in the axial direction of the threshing cylinder, the axis of the pressure lever is enabled to be coincident with the axis of the discharge hole, and the corn cobs can be pushed into the threshing cylinder by pressing the lever. Corn kernels and corn cobs obtained after threshing penetrate through the discharge hole and then enter a material collecting box or a packing auger or a conveying belt.

After one corn cob is threshed, the lever is lifted up, so that the next corn cob can be prevented from being threshed between the pressure rod and the top of the threshing cylinder.

The utility model utilizes the lever principle to feed, so that the feeding operation can be carried out by smaller external force in the actual operation, and the labor intensity of workers is reduced; meanwhile, the pressing rod is used for pushing materials, so that the situation that the blades on the threshing cylinder can cut fingers of workers when the materials are returned by bare hands is avoided.
