Connecting structure for connecting silencer and silencer tail pipe of corn harvester

Abstract

The invention relates to a connecting structure for connecting a silencer and a silencer tail pipe of a corn harvester. The connecting structure comprises a silencer and a silencer tail pipe and is characterized in that an air outlet pipe is vertically arranged on the silencer, one end of the silencer tail pipe is an air vent, the other end of the silencer tail pipe is connected with the air outlet pipe by virtue of a clamp, a reducing pipe joint is arranged at a end, connected with the silencer air outlet pipe, of the silencer tail pipe, the outer diameter of the reducing pipe joint is larger than the outer diameter of the silencer tail pipe, the inner diameter of the reducing pipe joint is larger than the inner diameter of the silencer tail pipe, and a positioning table is formed on the inner walls of the reducing pipe joint and the silencer tail pipe. By adopting the technical scheme, depth of the silencer tail pipe inserted into the silencer air outlet pipe is consistent and therefore assembling consistency is improved; fixation is reliable, and tail pipe fastening after long-time operation is better compared with a common plugging type scheme; besides, the connecting structure provided by the invention has the advantages of simple structure, reasonable design and improved assembling efficiency.

Description

technical field [0001] The invention belongs to the technical field of corn harvesters, in particular to a connection structure between a muffler of a corn harvester and a tail pipe of the muffler. Background technique [0002] At present, in most cases, the connection between the muffler of the corn harvester and the tail pipe of the muffler adopts a common plug-in scheme, and the outer diameter of the outlet pipe of the muffler is the same as the inner diameter of the tail pipe, and is fixed by a clamp; but in actual assembly, it is greatly affected by manual assembly factors. As a result, the length of the tailpipe inserted into the muffler is difficult to control; and it is easy to shake after working for a long time. Now, design optimization and improvement are carried out to solve this problem, in order to facilitate the fixing of the muffler tail pipe. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present i...
