Design of a straw picking and cutting device
WebIts purpose was to compress the straw before cutting. The clamp was held by a narrow length of iron bar which extended vertical suits cut in both sides. In pre - 1800 form, this bar had looped ends from which ropes drew the clamp down on to the straw. But, in order to move the straw forward after each cut, the clamp had to WebA chopping-type straw returning machine, composed of the frame, pressure roller, transmission device and straw cutting device, was developed. The pressure roller was located at the front of the machine, and was designed to press the standing or lying straws forward in the direction of machine movement.

WebNov 1, 2024 · Therefore, we set the DCS range to 5–65 mm, and the CWS was taken as 0.1–0.6 m/s in the simulation test [17,33]. According to the design calculation of the picking speed ratio of the pickup device, the picking requirement can be satisfied when the speed of the strip brush roller shaft is 65r·min-1. WebIt is the operation of cutting, picking, plucking and digging or a combination of these operations for removing the crop from under the ground or above the ground or removing the useful part or fruits from plants. Harvesting action can be done by four ways: 1) Slicing action with a sharp tool. 2) Tearing action with a rough serrated edge
