Harvester with protective ladder and lifting lower header capable of evenly chopping straws and preventing smashed straws from splashing

Abstract

The invention discloses a harvester with a protective ladder and a lifting lower header capable of evenly chopping straws and preventing smashed straws from splashing. The harvester consists of a lower header and a protective ladder, wherein the lower header is hinged on the front bridge of the harvester and consists of a lower header main frame, a lower harvesting mechanism, a straw smashing mechanism, a transmission mechanism and a lower header lifting mechanism; a first right-angled side for stopping an angle iron is welded on the lower edge behind a blocking cover; and the lower header lifting mechanism consists of a lower header lifting oil cylinder, a lower header lifting oil cylinder upper seat and a lower header lifting oil cylinder lower seat. According to the harvester with the protective ladder and the lifting lower header capable of evenly chopping straws and preventing smashed straws from splashing, the remaining straw parts can be harvested and smashed after grains are harvested, and the feed-in quantity of the harvester can be lightened; cutting stubbles are low and flat, thus facilitating tillage; the cutting and smashing efficiency of straws are high, the straws are evenly smashed, and the smashed straws cannot splash; the lower header can be lifted up and down, thus controlling the height of the cutting stubbles and being capable of avoiding barriers and protecting the safety of equipment; and the arranged protective ladder not only can be used for safely and conveniently climbing, but also can be used as a safety guard.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester with a protective ladder for evenly crushing stalks and a stalk-proof lifting and lowering platform. 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 threshing effect, the machine is...

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
