Lifting type lower cutting table capable of smashing straw and preventing smashed straw from splashing

Abstract

The invention discloses a lifting type lower cutting table capable of smashing straw and preventing smashed straw from splashing. The lifting type lower cutting table is hinged to a front axle of a harvester and comprises a lower cutting table main frame, a lower cutting mechanism, a straw smashing mechanism, a transmission mechanism and a lower cutting table lifting mechanism; blocking angle iron used for preventing the smashed straw from splashing is fixedly connected to the back portion of a blocking cover of the lower cutting table main frame; the lower cutting table lifting mechanism comprises a lower cutting table lifting oil cylinder, a lower cutting table lifting oil cylinder upper base and a lower cutting table lifting oil cylinder lower base. According to the lifting type lower cutting table capable of smashing the straw and preventing the smashed straw from splashing, straw portions retained after grain harvesting can be cut and smashed, the feeding amount of the harvester is decreased, the machine loss and the threshing load are reduced, and the threshing effect is improved; cut stubbles are low and flat, and therefore ploughing is convenient; the straw cutting and smashing efficiency is high, and the smashed straw cannot splash; meanwhile, lifting can be achieved, therefore, the cut stubble height can be controlled, and the cutting table can keep away from obstacles, so that equipment safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a lift-type lower cutting platform capable of crushing straw and preventing the splashing of the broken straw. 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 d...

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

In addition, the crushed stalks splash backward under the action of centrifugal force, and the broken stalks fall into the transmission system and hydraulic system to damage the machine, and also affect the driver's sight and cause accidents; the header is easy to hit obstacles and damage machinery and equipment
