Adjustable subsoiler fixing device

Abstract

The invention relates to an adjustable subsoiler fixing device. The device includes a depth adjusting assembly, an angle adjusting assembly and a shovel support; the depth adjusting assembly includes a guide cylinder, a shovel handle and a depth adjusting component; the upper portion of the shovel handle is movably installed in the guide cylinder, and the shovel handle can slide up and down along the guide cylinder; the depth adjusting component includes an adjusting handle, a screw rod and a fixing screw, the upper end of the screw rod is connected with the adjusting handle, and the lower part of the screw rod passes through the right side of the shovel handle and then is sequentially and rotatably matched with two fixing nuts through threads; through rotation of the adjusting handle, the two fixing nuts are driven to move up and down along the screw rod, and the in-soil depth of a subsoiler is adjusted. The angle adjusting assembly includes an angle adjusting base and a safety pin; the in-soil angle of the shovel handle can be adjusted. The device has an overload protection function, when the subsoiler is not dismantled and a depth limiting wheel does not need to be independently installed, the cutting depth and angle of the subsoiler conducting tillage in soil can be simply and rapidly adjusted, the adjustment time is shortened, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a fixing device with overload protection and capable of adjusting the depth and angle of plowing a subsoiler into the soil. Background technique [0002] With the promotion of conservation tillage technology, more and more attention has been paid to the research of subsoiling technology and machine tools. Subsoiling technology is a widely used method of soil cultivation. The purpose of not turning the soil, optimizing the soil structure and reducing soil water erosion. At present, the domestic subsoiling shovel handle is mainly fixed by bolts, that is, the subsoiling shovel handle is directly connected to the frame through bolts. This fixing method is relatively firm, but there are still the following problems: 1. The subsoiling shovel handle and the frame It is a rigid connection and cannot adjust the entry angle of the subsoiler shovel in different s...

Problems solved by technology

At present, the domestic subsoiling shovel handle is mainly fixed by bolts, that is, the subsoiling shovel handle is directly connected to the frame through bolts. This fixing method is relatively firm, but there are still the following problems: 1. The subsoiling shovel handle and the frame It is a rigid connection and cannot adjust the entry angle of the subsoiler shovel in different soil environments (and keep the frame level); 2. According to the traditional method to determine the depth of the subsoiler shovel into the soil, it is necessary to set the depth limit of different processing parameters separately Not only is the process of replacing the depth-limiting wheel time-consuming and laborious, but the installation of the depth-limiting wheel will occupy the use space of the frame; 3. During the cultivation process, the subsoiler encounters external impacts such as rocks and crop stubble or is subjected to loads. When it is too large, if there is no measure for overload protection, the subsoiler is easily deformed or even broken
