Adjustable-height crop straw compression chamber

Abstract

The invention discloses an adjustable-height crop straw compression chamber, comprising a compression chamber body, a piston slidably arranged in the compression chamber, a piston drive mechanism, a height adjusting mechanism and a posture holding structure. The compression chamber body comprises an upper plate, a lower plate, a left structure and a right structure, and the left structure and theright structure close the left side and the right side of the compression chamber when the upper plate and the lower plate are in relative movement; the height adjusting mechanism is used for adjusting height of the upper plate and / or the lower plate; the piston comprises a fixed piston and a movable piston connected elastically, and the movable piston can do up and down elastic expansion relativeto the fixed piston along with moving of the upper plate and / or the lower plate; the piston drive mechanism is used for driving the fixed piston to slide; the posture holding structure is used for keeping the fixed piston and the movable piston doing relative translation rather than relative rotation when the fixed piston and the movable piston are in relative expansion. The adjustable-height crop straw compression chamber can be used for crop straw bundling tests, and has wide application scope as the height of the compression chamber most suitable for the crop straw bundling work can be acquired according to different types of crop straws.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a height-adjustable crop straw compression chamber. Background technique [0002] As a renewable resource, crop straw has huge economic, social and ecological benefits. Because the straw material is loose, the bulk density is small, the collection takes up a lot of space, the transportation efficiency is low, and the cost is high, so the collection, storage and transportation link has always been the primary problem restricting the comprehensive utilization of crop straw. [0003] Although there are various types of crop straw collection and bundling machines in China, most of the crop straw collection and bundling machines imitate foreign mature products and lack test data as support. Therefore, the operation effect of the bundling machine is not very good. At present, when carrying out the crop straw bundling test, only a fixed-height compression chamber can be...

Problems solved by technology

Because the straw material is loose, the bulk density is small, the collection takes up a lot of space, the transportation efficiency is low, and the cost is high, so the collection, storage and transportation link has always been the primary problem restricting the comprehensive utilization of crop straw.

[0003] Although there are various types of crop straw collection and bundling machines in China, most of the crop straw collection and bundling machines imitate foreign mature products and lack test data as support. Therefore, the operation effect of the bundling machine is not very good

At present, when conducting crop straw baling experiments, only a compression chamber with a fixed height can be used for the test, and it is impossible to know the height of the compression chamber most suitable for crop straw baling operations through the test
