Agricultural rotary cultivator

Abstract

The invention discloses an agricultural rotary cultivator. The agricultural rotary cultivator comprises a frame, a rotary excavating device, a soil scattering device, a gas-liquid supply and a drivingdevice; the frame is provided with a vertical beam and multiple cross beams which are crossed to form four included angles, a circular shaft is arranged at the junction so as to make the vertical beam and the cross beams rotate relatively, the first included angle and the third included angle are each internally provided with a telescopic part, and the two ends of the telescopic part are connected to the vertical beam and the cross beams respectively to conduct telescopic adjustment on the included angles; the second included angle and the fourth included angle are each internally provided with an elastic part, and the two ends of the elastic part are connected to the vertical beam and the cross beams respectively so as to elastically pull or support the vertical beam and the cross beams;any one end of the vertical beam is detachably provided with a hook connected with a trailer; the rotary excavating device is hung on the cross beams; the soil scattering device is hung on the crossbeams and located behind the rotary excavating device, the soil scattering device comprises an air cannon, one end of the air cannon is fixed to the cross beam, and the other end extends downwards toblow apart soil; the gas-liquid supply device is arranged on the upper portion of the frame; the driving device is arranged on the frame.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and more specifically, the invention relates to an agricultural rotary tiller. Background technique [0002] The rotary tiller is an indispensable part of modern agriculture. In the existing agricultural machines, in order to achieve the effect of loosening the soil, the rotary digging knife is usually set to plow the land first, and then the soil clods are chopped with the soil breaking knife. This kind of farming machine has the following disadvantages: first, the soil is easy to adhere to the rotary digging knife or the soil breaking knife, which requires manual cleaning, which is time-consuming and laborious. If it is not cleaned, the farming machine will be dragged down, which consumes fuel and time; The soil efficiency is not high, and the effect is not good. In order to obtain crushed soil with a certain particle size, it is usually necessary to slow down the speed of the ag...

Problems solved by technology

This kind of farming machine has the following disadvantages: first, the soil is easy to adhere to the rotary digging knife or the soil breaking knife, which requires manual cleaning, which is time-consuming and laborious. If it is not cleaned, the farming machine will be dragged down, which consumes fuel and time; The soil efficiency is not high, and the effect is not good. In order to obtain crushed soil with a certain particle size, it is usually necessary to slow down the speed of the agricultural machine, and the rotary digging knife and the soil crushing knife repeatedly perform rotary digging and cutting on the soil to achieve a smaller particle size. Broken soil, which greatly reduces the efficiency of tillage

Third, the rotary digging knives and soil breaking knives produce a lot of dust during the rotation process, which affects the work of the cultivators and also pollutes the air to a certain extent
