Novel tractor-drawn avoidance hay mower

Abstract

The invention provides a novel tractor-drawn avoidance hay mower. The hay mower adopts a power output transmission shaft of a tractor as a power source, and a plurality of fixed mowing cutter discs are connected with an avoidance mowing cutter disc mounted on a rotating arm through a belt pulley. The avoidance mowing cutter disc mounted on the rotating arm adopts a belt pulley transmission mode, and a transit belt pulley at the other end is coaxial with the fixed end of the rotating arm. An avoidance reset elastic device is connected between the rotating arm and a mounting frame. The hay moweris designed, wherein when the hay mower encounters an obstacle during running, the rotating arm of the mowing cutter disc can achieve avoidance under the pressure of an external force, and automaticresetting after the obstacle is passed by is achieved. Through a transit transmission mode design of the fixed end of the rotating arm and the avoidance mowing cutter disc on the rotating arm, the structural complexity of power connection and conversion is simplified, the production cost is reduced, and favorable conditions are created for large-scale popularization and application of such machinery.

Description

technical field [0001] The invention relates to the related fields of agriculture, forestry and orchard machinery, and specifically designs an avoidance-type mowing and weeding machine that can be used around the trunks of orchards and vineyards, around the trunks of gardens, on both sides of expressways and under the supports of photovoltaic solar power stations. Background technique [0002] In recent years, with the further promotion and popularization of the ecological agricultural planting mode, the orchard weeding mode has gradually replaced herbicides and rotary tillage methods, and has gained more and more recognition. However, in the orchard mowing operation, the mowing between the rows of fruit trees is relatively easy to handle because of the working space, but the mowing between the trees has always lacked efficient and economical operating tools. At present, it is common to carry out manual work with a small gasoline engine-powered brush cutter. The operation in...

Problems solved by technology

However, in the orchard mowing operation, the mowing between the rows of fruit trees is relatively easy to handle because of the working space, but the mowing between the trees has always lacked efficient and economical operating tools. At present, it is common to carry out manual work with a small gasoline engine-powered brush cutter. The operation in related areas has low operation efficiency and high labor intensity, so it is not suitable for large-scale fruit plantations

Since 2017, orchard avoidance lawn mowers driven by hydraulic motors to avoid mowing cutters have appeared in China, imported or imitated from foreign products. However, the design and production costs of this kind of machinery are relatively high, which is not conducive to large-scale domestic popularization. Restricted the further popularization and application of domestic orchard grass growth mode
