Chain tilling machine

Abstract

The invention discloses a chain tilling machine. The chain tilling machine comprises a machine frame, a transmission shaft fixed to the machine frame, transmission gears arranged on the transmission shaft, a square beam hinged to the transmission shaft, tensioning frames connected with the square beam, driven gear shafts, driven gears, chains, tilling blades and hydraulic rods, wherein the driven gear shafts and the driven gears are arranged on the tensioning frames, the chains are used for connecting the transmission gears and the driven gears, the tilling blades are arranged on the chains, and the two ends of each hydraulic rod are hinged to the square beam and the machine frame respectively. The square beam can buffer and reduce reverse impact force on the machine when the tilling blades collide with hard objects in a field, a transmission device of the machine is protected, and the service life of the machine is prolonged. The tensioning frames which are independent of one another easily increase the depth of soil loosening. The chain tilling machine can smash crop straw and weed at a time and mixes the smashed crop straw and weed into soil, and completes deep loosening, clod disintegrating, land formation and other tillage operation.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a chain tiller. Background technique [0002] After the crops are harvested, there are usually a lot of stalks and leaves left. For some crop stalks with more fibers and long, such as sugarcane leaves and corn stalks, they are usually burned by burning, and then plowed to plow the ground. Crush the soil with a rotary tiller. Straw returning to the field is a measure of fertilizing soil fertility and increasing production that is generally valued in the world today. It can increase fertilizer and increase production while avoiding air pollution caused by straw burning. Straw returning can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and root development of crops. [0003] In recent years, our country is also promoting some crop straw grinders, that is, to crush the crop straw before the...

Problems solved by technology

[0003] In recent years, our country is also promoting some crop straw grinders, that is, to crush the crop straw before the land preparation, and then plow the land and the rotary tiller to prepare the land. The cutter shaft, the effect and efficiency of cultivated land are not ideal

At present, the field of agricultural machinery lacks an agricultural machinery that can simultaneously crush crop stalks and weeds, loosen broken soil and level the land.
