Exhaust pipe fixing frame of rice harvester

Abstract

The invention discloses an exhaust pipe fixing frame of a rice harvester. The exhaust pipe fixing frame comprises a mounting piece, a fixing piece, a connecting pipe, a connecting bent pipe and a connecting piece. The connecting pipe is welded to the surface of the mounting piece. The fixing piece is welded to the lower surface of the connecting pipe. Anti-rusting spray paint is sprayed to the surface of the fixing piece. The surface of the fixing piece is connected with reinforcement connecting structures. Nut fixing grooves are formed in the surface of the fixing piece, and a fixing screw hole is formed in each nut fixing groove. The connecting bent pipe is welded to one end of the connecting pipe. The surface of the connecting bent pipe is wrapped by a fireproof protection layer. The surface of the connecting bent pipe is connected with the connecting piece in a sleeved manner. Connecting screw holes are formed in the corner of the surface of the connecting piece. A sealing gasket is laid on the surface of the connecting piece. In the exhaust pipe fixing frame, through the arrangement of the nut fixing grooves, nuts can be sleeved with the nut fixing grooves so as not to loose;and the fixing screw holes are distributed in equilateral triangle shapes, greater stability is achieved during fixing, and loosening is not prone to happening.

Description

technical field [0001] The invention relates to the technical field of rice harvester machinery, in particular to an exhaust pipe fixing frame of a rice harvester. Background technique [0002] China is a large agricultural country. The cultivation of rice can be traced back to seven thousand years ago. Rice is native to China. According to different methods, rice can be divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice. With the continuous development of science and technology The development of agriculture also began to be continuously mechanized. The harvester was invented by Cyrus McCormick. The rice harvester is an integrated machine for harvesting rice crops. It completes harvesting, threshing, and concentrates the grains into storage at one time Then, the grain is transported to the transport vehicle through the conveyor belt, which is compared with the traditional manual harvesting, which greatly improves ...

AI Technical Summary

Problems solved by technology

[0003] The exhaust pipe fixing frame of the rice harvester is a fixing device for the exhaust pipe of the rice harvester. The structure of the exhaust pipe fixing frame of the traditional rice harvester is relatively simple, because the vibration amplitude of the rice harvester is relatively large when it is working, and it is easy to appear The fixing is not firm enough, causing the exhaust pipe to loosen. At the same time, some poor quality rice harvesters have a short service life for the exhaust pipe fixing frame
