Drive arm: This assembly realizes the selective clamping and pulling harvesting operation of cabbage crops. It has the characteristics of simple structure, convenient and reliable clamping and pulling, good harvest quality, strong selectivity, wide application range, and is conducive to improving agricultural economic benefits.

Description

Pulling claw assembly for cabbage crops

technical field

The invention belongs to agricultural machinery, and mainly relates to an operating assembly on a harvesting machine tool for spherical cabbage crops.

Background technique

For the harvesting of bulbous vegetables, including cabbage, the traditional method is to cut them off the surface of the ground with a sickle or shovel, and then pick them up manually. Poor quality and high operating cost are the problems that need to be overcome and solved urgently. In recent years, harvesting machines for head crops have been developed. However, due to the use of spiral cone extraction devices in the harvesting structure, or the use of left and right supporting plates with elastic mesh belt structures, in actual extraction operations, not only is it easy to cause crops damage, the quality of the harvest is reduced, especially the inability to selectively harvest according to the maturity of the head crops, which affects the economic benefits of agricultural production.

Contents of the invention

The purpose of the present invention is to solve the problems in the above-mentioned prior art and combine the actual needs of cabbage harvesting operations to design and provide a cabbage crop pulling claw assembly to achieve the purpose of selectively pulling and harvesting.

The object of the present invention is achieved in this way: the upper swing arm is symmetrically hingedly installed on the upper side of the two-way hydraulic cylinder, and the lower swing arm is hingedly installed symmetrically on the lower side of the two-way hydraulic cylinder at the position below the upper swing arm. The claw teeth are symmetrically hinged and installed on the symmetrically hinged upper swing arm and the lower swing arm, and the arm base is installed on the lower end of the cylinder rod of the two-way hydraulic cylinder. Install the driving arm to form the cabbage crop pulling claw assembly so far.

The invention realizes selective clipping and harvesting operations for cabbage crops, and has the characteristics of simple structure, convenient and reliable clipping, good harvest quality, strong selectivity, and is beneficial to the improvement of agricultural economic benefits. The assembly can also be used for extraction operations of tuber crops such as sugar beets and radishes.

Detailed ways

Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A claw assembly for extracting cabbage crops, in which an upper swing arm 3 is symmetrically hinged on the upper side of a two-way hydraulic cylinder 2, and mutually symmetrical hinges are located on the lower side of the two-way hydraulic cylinder 2 and located below the upper swing arm 3. The lower swing arm 4 is evenly installed, and the claw teeth 8 are symmetrically hinged and installed on the upper swing arm 3 and the lower swing arm 4 of the symmetrical hinge. The arm base 7 is installed on the lower end of the cylinder rod 5 of the two-way hydraulic cylinder 2. The drive arms 6 are respectively symmetrically hinged at the positions between the lower swing arm 4 and the arm seat 7 .

During the clamping operation, the extraction claw assembly is installed on the lower end of the boom 1 of the harvesting implement through the two-way hydraulic cylinder 2, and the telescopic reciprocating linear motion of the oil cylinder rod 5 of the two-way hydraulic cylinder 2 is used. 6 and the lower swing arm 4, and under the cooperative control of the upper swing arm 3, realize the closing and opening of the lower side of the symmetrically assembled claw teeth 8, and complete the clamping and dropping of cabbage crops.
