Saw-blade type field straw returning machine

Abstract

The invention discloses an agricultural machine, particularly a saw blade-type straw returning machine for in-situ pulverizing the straw of crops such as maize and returning the pulverized straws to the field. The machine comprises a tractor, a straw discharging device, a straw-pulverizing device and a power transmission device. The straw discharging device is the helical drum-type straw transverse discharge device, wherein the helical drum is arranged at the front part of the drum holder and the transmission shaft is arranged at the rear part of the drum holder. The straw discharging device is arranged at the front part of the tractor. The straw-pulverizing device is the saw blade-type straw-pulverizing device, wherein the saw blade shaft provided with a plurality of saw blades and the barbed shaft provided with a plurality of rows of barbed nails are arranged at the rear part of the main body of the straw-pulverizing device, the saw blade shaft is positioned in front of the barbed shaft, and a plurality of rows of the barbed nails are positioned among the saw blades in the axial direction. The straw-pulverizing device is arranged at the rear part of the tractor. The saw blade-type straw returning machine ensures the short length and the uniformity of the processed straw, allows the processed straw to be sown by a sowing machine after plowing underground, and reduces the fuel consumption by more than two thirds of that in the prior art.

Description

technical field [0001] The invention relates to an agricultural machine, which is a saw-blade straw-returning machine for crushing corn and other crop straws on the spot and returning them to the field. Background technique [0002] At present, the known straw returning machine is to dump the straw vertically, and the knife is cut and crushed. Because the knife needs to cut the straw with the help of the ground, the blade is easy to wear, causing part of the straw and straw leaves to be cut continuously, which affects the cultivation of the land. This working method of the knife makes the fuel consumption of the tractor large. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a saw-blade straw-returning machine which is small in size and uniform in length, saves fuel, is simple to manufacture, and is easy to popularize. [0004] The technical solution adopted by the present invention to sol...
