A multifunctional harvesting mechanical vibrating screen electric adjustment device

Abstract

The invention discloses an electric adjusting device for a multifunctional harvesting mechanical vibrating screen, comprising a vibrating screen body and an adjusting mechanism, the vibrating screen body comprising a mounting base, an adjusting sheet and a fish scale screen sheet, and the adjusting mechanism comprising a screw motor and an adjusting flexible shaft. One end of the adjusting flexible shaft is connected with the screw motor, and the other end of the adjusting flexible shaft is connected with the adjusting sheet. The adjusting mechanism performs power output through the work of the screw motor, the adjustment accuracy is better, and the controllability is higher. The beneficial effect is that the angle adjustment of the fish scale screen is carried out through the adjusting mechanism. Compared with the traditional fixed or manual vibrating screen for adjusting the angle of the fish scale screen, the operation of the present invention is simple and convenient, and the vibrating screen can be set to one-stage or one-stage vibrating screen. The multi-stage type can be adjusted in one or more stages. Through the setting of the displacement sensor, the opening and closing angle of the fish scale screen can be detected in real time, which makes the angle adjustment of the fish scale screen more intuitive.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an electric adjustment device for a multifunctional harvesting machinery vibrating screen. Background technique [0002] With the development of society, the market demand for agricultural machinery continues to update and expand, and the demand for multi-functional combined harvesting machinery for different crops is becoming more and more prominent. The fish scale screen of the vibrating screen has a fixed angle. When harvesting for different functions, it is necessary to replace the vibrating screen with different angle fish scale screens. The replacement of the vibrating screen requires manpower and wastes a lot of time, thus affecting the work of the harvester. Although there are some vibrating screens that can adjust the angle of the fish scale screen, such vibrating screens are generally adjusted manually by mechanical structure, which is inconvenient to ope...

[0002] With the development of society, the demand for agricultural machinery market is continuously updated and expanded, and the demand for multifunctional combined harvesting machinery for different crops is becoming more and more prominent. The opening and closing angle of the multifunctional combined harvesting machinery vibrating screen scale screen affects the screening accuracy of crops. The fish scale screen of the vibrating screen has a fixed angle. When harvesting for different functions, it is necessary to replace the vibrating screen with fish scale screens of different angles. The replacement of the vibrating screen requires manpower and wastes a lot of time, which affects the work of the harvester. Efficiency, although there are some vibrating screens that can adjust the angle of fish scale sieves, but such vibrating screens generally use mechanical structure for manual adjustment, which is inconvenient to operate and difficult to achieve the desired effect
