Semi-automatic lifter for whole-feed combine harvester

Abstract

The invention discloses a semi-automatic lifter for a whole-feed combine harvester. The semi-automatic lifter comprises a pull plate, an operation bent rod, a lock pin and a spring. The bottom of the pull plate is connected with a front chopper. The pull plate is provided with a first waist hole in a length direction. The external projection of the operation bent rod is provided with a fixing sheet which is hinged with one side of top of the pull plate. The spring is connected between the fixing sheet and top of the pull plate. The bottom end of the operation bent rod is provided with a second waist hole. A guiding rod which is arranged above the bottom of the first waist hole is vertically arranged outside the pull plate. The lock pin is arranged in the guiding sleeve. The outer end of the lock pin is hinged with the second waist hole. Through the manner of the invention, the semi-automatic lifter for the whole-feed combine harvester has advantages of realizing simple operation and semi-automatic control, realizing no requirement for getting of the combine harvester for entering a space below a cutting table for operation, and eliminating potential hazards in mounting.

Description

technical field [0001] The invention relates to the field of harvesters, in particular to a semi-automatic lifter for a full-feed combine harvester. Background technique [0002] my country is a large agricultural country, and the cultivation of wheat and rice occupies the absolute proportion of my country's crops. In recent years, with the gradual improvement of my country's productivity level, the use of large combine harvesting machinery has also been widely popularized. [0003] The use of combine harvesting machinery has left a large amount of crop stubble in the farmland, which has brought great disturbance to the reseeding of crops. With the aggravation of environmental pollution caused by the burning of crop straws, the front-end equipment has been more and more used. [0004] With the continuous improvement of grain production, there are more and more stems, and the workload of the front-end equipment will also increase accordingly, and the front-end equipment wil...

Problems solved by technology

[0004] With the continuous improvement of grain production, there are more and more stems, and the workload of the front-end equipment will also increase accordingly, and the front-end equipment will become heavier and heavier. It is getting worse and worse. The old-fashioned simple lifting equipment mainly uses steel plates or iron chains to achieve lifting. When the state is switched, the operator often needs to get off the car to handle it. It needs to be improved.

Due to the position of the front equipment and the rear and lower side of the header, the header needs to be lifted high during processing, and personnel need to drill under the header to handle the connection parts, which brings great safety hazards to the operators, and even injury accident
