Double-shaft rotary cultivator

Abstract

The invention discloses a double-shaft rotary cultivator which comprises a main frame and a rear supporting plate. The back side of the main frame is connected with the rear supporting plate, a main cutter shaft is arranged in the main frame, a plurality of uniformly distributed rotary tillage blades are arranged on the main cutter shaft, and a main gear box is arranged in the middle of the main frame. A front beam of the main frame is provided with a portal frame, left and right suspension plates are arranged on two sides of the lower portion of the portal frame and form three-point suspension with the portal frame, the upper portion of a side gear box is provided with a shift lever for adjusting the speed of rotation, and two lengthened shafts of the main gear box and an upper spline shaft of the side gear box are connected through universal joints to transmit power. By adopting the double-shaft rotary cultivator, the defect can be overcome that traditional rotary cultivators are divided into single-shaft rotary cultivators and double-shaft rotary cultivators, single shafts only utilize rotary tillage blades on the shafts for rotary tillage in use, and accordingly the rotary tillage effect is poor and rotary tillage is unthorough; although each traditional double-shaft rotary cultivator is provided with two shafts with rotary tillage blades, the side gear box of the transmitted double-shaft rotary cultivator is single in rotation speed, an auxiliary shaft is also constant in rotation speed, and different agriculture demands cannot be met.

Description

technical field [0001] The invention relates to the field of rotary tillers, in particular to a two-axis rotary tiller. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing; at the same time, it can chop the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. The traditional rotary Tillers are divided into two types: single-shaft and double-shaft. When the single-shaft is in use, only the rotary blade on one shaft is used for rotary tillage, so there are defects of poor rotary tillage effect and incompleteness. The traditional double-shaft rotary tillage Although the machine has two shafts with rotary tillers, the rotating speed of the transmission box on the side of the two-axis rotary tiller is single, and ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of two-axis rotary tiller, which can solve the problem that traditional rotary tillers are divided into two types: single-axis and double-axis. Thereby rotary tillage effect is poor, not thorough defective, and although traditional two-axis rotary tiller has two axles with rotary blades, the rotating speed of the side transmission box of the two-axis rotary tiller of transmission is single, and the rotating speed of countershaft is also low. Constant, unable to meet different agronomic needs, such as different soil moisture conditions including soil viscosity, humidity, broken soil rate and toughness of residual straw
