Position regulating mechanism of main transmission box of backpack corn harvester

Abstract

The invention relates to a position regulating mechanism of a main transmission box of a backpack corn harvester, belonging to agricultural machinery. High and low level regulating beams are respectively assembled on a left longitudinal beam and a right longitudinal beam through an upper clamp plate and an upper U-shaped card combination, and lower clamp plates are fixedly installed on the lower-side parts of the high and low level regulating beams. The left-side part and the right-side part of a transverse level regulating beam are born on the lower parts of the high and low level regulating beams on the left longitudinal beam and the right longitudinal beam through a lower U-shaped card combination and the lower clamp plates. The part positioned between the left longitudinal beam and the right longitudinal beam on the transverse level regulating beam is provided with a main transmission box installation plate. The position regulating mechanism of the main transmission box of the backpack corn harvester has the advantages of simple structure, simpleness and convenience in regulation, high generalization degree and wide suitable machine types and can cause the backpack corn harvester with one kind of structure to be installed with various types of four-wheel tractors to form ta complete set to use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a position adjustment mechanism of a main transmission box installed in conjunction with a backpack corn harvester and a four-wheel tractor. Background technique [0002] Due to the large number of manufacturers of medium and small power four-wheel tractors in my country, the product models produced are complicated and the structures are different, which makes it inconvenient to install the knapsack corn harvester with the four-wheel tractor, that is, a knapsack corn harvester can only be used with One type of four-wheel tractor is installed as a complete set, and the degree of generalization is greatly reduced, especially the positions of the power output shafts on the rear of various types of four-wheel tractors are different, and the main transmission boxes on the existing backpack corn harvesters of many varieties cannot The adjustment of the position resulted in the failure of th...
