Harvester provided with protective ladder and lifting type lower header capable of smashing straw and preventing smashed straw from splashing

Abstract

The invention discloses a harvester provided with a protective ladder and a lifting type lower header capable of smashing straw and preventing the smashed straw from splashing. The harvester comprises the lower header and the protective ladder, and the lower header is hinged to a front axle of the harvester. The lower header comprises a lower header main frame, a lower cutting mechanism, a straw smashing mechanism, a transmission mechanism and a lower header lifting mechanism. Blocking angle iron is further fixedly connected with the rear portion of a shield of the lower header main frame. The lower header lifting mechanism comprises a lower header lifting oil cylinder, a lower header lifting oil cylinder upper base and a lower header lifting oil cylinder lower base. The harvester provided with the protective ladder and the lifting type lower header capable of smashing straw and preventing the smashed straw from splashing can cut and smash straw left after grain harvesting, and the feed quantity of the harvester is reduced. Cutting stubbles are short and flat so that tillage can be convenient. The straw cutting and smashing efficiency is high, smashing is uniform, and the smashed straw cannot splash. The lower header can ascend and descend so as to control the height of the cutting stubbles and avoid obstacles to protect equipment safety. The arranged protective ladder makes people climb safely and conveniently, and can also be used as a safety guardrail.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with a lift-type lower cutting platform with a protective ladder capable of crushing stalks and preventing the stalks from splashing. Background technique [0002] At present, the country advocates that the straw should be returned to the field after harvesting, and then deeply plowed into the soil to fertilize the field. It is strictly forbidden to burn the straw. At the same time, the straw should be chopped and collected or returned to the field or not crushed. Also harvest the stalk portion of the grain. The cutting devices of today's harvesters are all composed of single-layer headers, which harvest the ears and stalks of the grain together, feed the cut grain stalks and ears of grain into the harvester, complete threshing and discharge the stalks . The disadvantages are that the cut stalks are long, the feeding amount is large, which affects the...

AI Technical Summary

Problems solved by technology

The disadvantages are that the cut stalks are long, the feeding amount is large, which affects the threshing effect, the machine is damaged, the energy consumption is high, and the efficiency is low; The long straw is not easy to decompose after being returned to the field and becomes the base fertilizer
