Plow harrow device for soil turning

Abstract

The invention relates to the field of agricultural equipment, in particular to a plow harrow device for soil turning. The device comprises a rack and a plough plate arranged on the rack, front walking wheels and rear walking wheels are arranged at the front and rear ends of the rack respectively, and the front walking wheels are connected with a driving device through a speed reduction device; a link assembly for automatically adjusting the in-soil depth of a ploughing plate is fixed to the lower middle of the rack, the ploughing plate is connected with a link mechanism, and a soil crushing mechanism is fixed to the rear end of the rack and connected with the rear walking wheels; a shaking mechanism for hammering the ploughing plate is arranged in the upper middle of the rack and can be connected with the soil crushing mechanism. According to the plow harrow device for soil turning, after the ploughing plate comes across hard objects, the link mechanism is used for automatically adjusting the in-soil depth of the ploughing plate, human participation is not needed in the whole process, the ploughing plate does not need to be adjusted multiple times, time and labor are saved, the production efficiency is improved, and the labor intensity is lowered.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a plow and harrow device for turning the soil. Background technique [0002] In order to facilitate the planting of crops and make the growth of crops more favorable, it is necessary to turn over the soil before sowing to improve the structure of the soil, enhance the air permeability, water retention and fertilizer retention of the soil, and create a new environment for the growth of crops. good conditions. At present, when carrying out land plowing operations, the agricultural machinery attachments and moldboards used often encounter hard soil, which will lead to increased resistance and greater damage to the moldboard. It is necessary to adjust the depth of the moldboard. After the board passes over the hard object, adjust the depth of the mouldboard to the initial state, which will increase the frequency of adjusting the mouldboard, time-consuming and laborious, and red...

At present, when carrying out land plowing operations, the agricultural machinery attachments and moldboards used often encounter hard soil, which will lead to increased resistance and greater damage to the moldboard. It is necessary to adjust the depth of the moldboard. After the board passes over the hard object, adjust the depth of the mouldboard to the initial state, which will increase the frequency of adjusting the mouldboard, time-consuming and labor-intensive, and reduce production efficiency. In view of this, we propose a plow rake device for soil plowing
