Agricultural machine disc harrow facilitating cleaning of soil attached to concave surface harrow blades

Abstract

The invention relates to the technical field of agricultural machinery, and discloses an agricultural machinery disc harrow facilitating cleaning of soil attached to concave harrow blades, the agricultural machinery disc harrow comprises a mounting bracket, a mounting rod is rotatably connected between the inner side walls of the mounting bracket through a bearing, and a group of disc harrows are fixedly mounted on the outer surface of the mounting rod; and a cross rod is rotationally connected between the inner side walls of the bracket through a bearing. According to the agricultural machine disc harrow facilitating cleaning of the soil attached to the concave surface harrow blades, the mounting support is connected with an agricultural machine, the agricultural machine drives the device to move to work, and during working, the disc harrow rotates to plough land and drives a mounting rod to rotate and drives a cross rod to rotate, and the cross rod drives a first bevel gear to rotate; a vertical rod is driven to rotate through a second bevel gear meshed with the first bevel gear, the vertical rod drives a scraper to rotate through a connecting rod, the scraper rotates to remove soil attached to the concave surface of the disc harrow, and therefore the effect that the soil attached to the disc harrow blade on the concave surface of the disc harrow is conveniently cleaned is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a disc harrow for agricultural machinery which is convenient for cleaning the soil attached to concave harrow blades. Background technique [0002] Disc harrow is a traditional farm tool in agricultural production. It used to be one of the necessary farm tools for farmers, and it is also one of Chinese martial arts equipment. It evolved from farm tools. The disc harrow is based on the working principle of harrowing, and uses groups of concave discs as working parts. During operation, under the action of the traction force of the tractor and the reaction force of the soil, the rake blade rolls forward, the blade of the rake blade cuts into the soil, cuts off the grass roots and crop residues, and makes the soil ridge rise along the concave surface of the rake blade to a certain height and then turns over and falls. During the operation, the fertilizer and pesticide...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a disc harrow for agricultural machinery that is convenient for cleaning the soil attached to the concave rake blades. When the disc harrow is attached to the harrow, it will cause the clogging of the harrow. Therefore, try to choose a time when the soil humidity is suitable for operation. In this way, the working time of the disc harrow is limited, which is inconvenient to use, and when the disc harrow is working, it will generate a lot of Dust floats in the low air, seriously affecting the physical and mental health of the staff
