Shredding and rubbing device for silage harvester

Abstract

The invention relates to a shredding and rubbing device for a silage harvester. The shredding and rubbing device comprises a shredding mechanism and a rubbing mechanism. The rubbing mechanism comprises friction blocks, middle cushion blocks and a concave plate. The friction blocks are fixedly connected to the lower ends of movable cutter bases, and the middle cushion blocks are arranged between the friction blocks and the movable cutter bases. The friction blocks comprise the left thread friction blocks and the right thread friction blocks. The left thread friction blocks are D-type left thread rasp bar steel, and the right thread friction blocks are D-type right thread rasp bar steel. The left thread friction blocks and the right thread friction blocks are installed on the movable cutter bases on the left side and the movable cutter bases on the right side respectively in a staggered mode. The concave plate is fixedly connected to the lower end of a shredding cylinder shell, and gap adjustment bolts are arranged on the two sides of the concave plate. In the working process, crops are cut into sections through movable cutters and fixed cutters, the crops are changed to be in a shred shape under the rubbing function of the concave plate and the friction blocks after cut into the sections, and quality of silage is improved.

Description

technical field [0001] The invention relates to the field of silage harvesting machinery, in particular to a chopping and kneading device for a silage harvester. Background technique [0002] Most of the crops in northern my country are ripe once a season, so there will be a shortage of forage in autumn and winter, especially fresh green forage. Most farmers feed on hay, which greatly reduces the nutritional content and palatability of forage. Through silage fermentation and processing, the silage produced is not only fresh and palatable, but also solves the problem of lack of forage grass in autumn and winter. [0003] Silage fermentation is a complex process of microbial activities and biochemical changes. During the silage fermentation process, there are many types of microorganisms involved in the activities. During normal silage, the carbohydrates in the plant are fermented by lactic acid bacteria in an anaerobic environment to produce a large amount of lactic acid, a...

Problems solved by technology

[0005] Some silage harvester manufacturers are equipped with simple kneading devices when harvesting silage. The kneading is mainly achieved by setting tooth plates on the concave surface of the concave plate, and crushing by friction between the chopping drum and the concave plate equipped with tooth plates. Feed, because the concave plate with the tooth plate is fixed, in actual use, it is found that when the silage passes through the concave plate with the tooth plate, the resistance becomes larger, and part of the silage will stay in the gap of the tooth plate, which will affect the machine. One-step throwing performance and easy clogging in the chopping drum
