Description

A cutting platform for ear-picking and stubble-cutting and stem-cutting of corn with upper ear

technical field

The invention relates to a corn ear picking device suitable for being installed on a corn harvester, belonging to the technical field of corn harvesters.

Background technique

The ear picking device is the key working part of the corn harvester. At present, according to the working principle, it can be divided into two types: roller type and plate type. The plate-type ear-picking device belongs to the passive ear-picking device. The root of the corn ear is clamped by the ear-stopping plate, and the corn stalk is forcibly broken by the stem-pulling roller to achieve the purpose of ear-picking. This device easily causes the problems of broken stems and blockage. The working principle of the roller type is to complete the ear picking operation by stretching and squeezing the corn stalk and ear by the conveying roller. In the existing roller-type ear picking devices, most of the conveying rollers adopt a structure with spiral ribs attached to the surface, which produces a force of squeezing and kneading on the root of the ear, which is very easy to gnaw the ear of corn, and cannot fundamentally solve the problem of the impact of the conveying roller on the ear of corn. The squeezing and gnawing effect. To solve this difficult problem, it is necessary to explore new principles and new devices.

Research has found that people use corn ear picking to bend and break the ear, and due to the special material composition of the hands, the extrusion force on the corn ear is very small, and there will be no damage to the corn phenomenon, which has become the basis for the study of new methods of corn ear picking .

Contents of the invention

The object of the present invention is to provide an upper-cracking corn ear-picking and stubble-cutting and stem-cutting platform, so as to overcome the disadvantages of the prior art.

In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: with the help of the results of bionics research, focusing on the innovation of the ear picking method, and by imitating the working principle of manual picking corn ears, the upper stalk connected with the corn harvesting frame is designed. Ear-type corn ear-picking, stubble-cutting and stem-cutting platform.

In conjunction with the accompanying drawings, the description is as follows: an upper ear picking and stubble cutting and stem cutting platform for corn, including a roller-plate combined ear picking device, a stem dialing mechanism and a stubble and stem cutting device, characterized in that: The roller-plate combined ear breaking unit consists of a pair of conveying rollers 2 and a pair of fringe retaining plates 1 placed below the pair of conveying rollers. When working, the mechanism is fixedly connected with the frame of the harvesting machine and is at a front height with the ground. It is configured in a low-back inclined state; the stalk sending mechanism is a telescopic rod-toothed mechanism, which is arranged behind the fringe breaking unit; the stubble cutting and stem cutting mechanism is composed of a stubble cutting device and a stem cutting device. The mechanism is set under the ear breaking unit, and the stem cutting mechanism is set under the stalk delivery mechanism; when working, the corn plant is guided by the clamping device into the roller plate combined ear breaking unit, so that the corn ear is under the conveying roller 2 , the stubble cutting device cuts off the plants entering the ear picking rollers, and the two oppositely rotating conveying rollers 2 clamp and guide the plants to move upwards and backwards. The corn stalks are bent and broken away from the plant, and the corn stalks after ear picking remain upright. The telescopic teeth 3 of the stalk delivery mechanism pull down the corn stalks, so that the corn stalks fall back to the ground, and the stem cutting device will cut the stalks back to the ground and return them to the field. .

The surface of the conveying roller 2 is provided with spiral ribs distributed in opposite directions, its core is made of rigid material, and the spiral ribs are made of flexible material; the fringe baffle 1 is placed under the conveying roller 2, It exists in pairs and is the main fringe breaking mechanism.

The front end of the gap between the pair of conveying rollers 2 is large and the rear end is small.

The operation mode of the pair of conveying rollers 2 is that they are positive to each other and rotate outwards counterclockwise.

The stem dialing mechanism is a telescopic rod-toothed mechanism, which is composed of telescopic teeth 3, eccentric rollers 4 and telescopic tooth slots 5, and its running direction is forward rotation.

The stubble cutting device is composed of a pair of stubble cutting blades 11 and a stubble cutting tube shaft 10 .

Described stem cutting device is made up of movable knife seat 8, movable blade 7 evenly installed, movable knife seat shaft 9 and fixed blade 6.

The beneficial effects of the present invention are: 1) The present invention imitates the bending principle of manual picking of corn ears, and can fundamentally solve the corn damage caused by the existing stretching extrusion method; Imitate the effect of picking corn ears by hand, effectively prevent the corn ears from being gnawed, and fundamentally solve the extrusion and gnawing effect of the conveying roller on the corn; 3) The conveying roller rotates outward to realize the upward transportation of the stalk; 4) The ear baffle catches the root of the corn ear to achieve the effect of manually breaking the corn; 5) The gap between the conveying rollers is larger than the diameter of the corn stalk, so there is no extrusion effect on the corn stalk, and the complete corn stalk can be obtained , It is also conducive to the comprehensive utilization of corn stalks.
