Device for testing cotton picking force

Abstract

The invention relates to a device for testing a cotton picking force. The device comprises a motor, a motor transmission wheel, a motor shaft, a transmission belt, a base, and a testing device, wherein the motor is fixed on the base; the testing device comprises a speed sensor,?a fixing piece,?a testing?transmission wheel,?a testing bearing seat, testing transmission shafts, a testing picking ingot clamping head and a picking ingot; the speed sensor is connected with the motor shaft via the fixing piece; the testing transmission wheel is arranged on the testing transmission shaft; the testing transmission shafts are arranged on the testing bearing seat; the testing bearing seat is connected with the base; the testing picking ingot clamping head is connected with the testing transmission shaft; the picking ingot is arranged on the testing picking ingot clamping head; and the motor transmission wheel is connected with the testing transmission wheel via the transmission belt. According to the device for testing a cotton picking force, a real picking situation in the field by the cotton picker ingot can be simulated in the lab by using different rotary speeds for the test on cotton picking force, defects that a testing device is hard to load by the prior cotton picker can be solved, the design is reasonable, the structure is delicate, and the operation is convenient.

[0002] At present, the spindle-type cotton picker has been popularized and used in a large area, but the technical update is relatively backward. The main reason is that the picking mechanism of the spindle-type cotton picker has not been established, which hinders the upgrading of cotton picker products.

Due to the relatively complex structure of the cotton picker, it is difficult to load the experimental device during the actual working process of the cotton picker, especially the test of the picking force of the cotton picking head under dynamic conditions cannot be carried out, and the picking force between the cotton and the husk cannot be tested. analyze

Existing force-measuring instruments can test the separation force of cotton and husks, but the requirements for the test conditions are relatively high, and the test needs to be carried out at a constant speed. The test method is: clamp the cotton and husks on the bench and measure the force On the instrument, the displacement platform of the fixed load cell moves at a constant speed to realize the separation force between the cotton and the husk, but this method can only test the separation force between the cotton and the husk under static conditions, and cannot test the cotton and husk under dynamic conditions. The separation force between the shells makes it impossible for the force measuring instrument to test the separation force between the dynamic cotton and the shells, and the picking force of the cotton picking head is particularly important for the quality of cotton picking. The parameter value for testing the cotton picking force is It is an important basis for the adjustment of the speed of the cotton picking head to study the relationship between the quality of cotton picking and the structure and speed of the picking spindles, and to optimize the structural parameters and working parameters of the picking spindles is a key technical means. Timing also plays a role
