2014
The invention discloses a feeder for crushing of crop straw material. The feeder comprises a feeding hopper, wherein the bottom part of the feeding hopper is provided with a rotary shaft, one end of the rotary shaft is fixedly arranged on the outer wall of the feeding hopper by a bearing, the other end of the rotary shaft penetrates through the bearing and is connected with an output shaft of a motor through an elastic coupling, the bottom part of the motor is welded with a motor frame, the bottom part of the motor frame is fixedly arranged on a support plate by a connecting rod, one side of the motor frame is fixedly arranged on the outside surface of the feeding hopper by a connecting rod, the rotary shaft is welded with a plurality of elastic teeth, and a 90-degree staggering structure is formed between the axially arranged elastic teeth. The feeder has the advantages that by controlling the rotation speed of the motor and the lifting angle of a retaining plate, the feeding amount can be controlled, the material is continuously and uniformly fed into a spiral conveying device, and the conveying property of the crop straw in the spiral conveying device is improved; the structure is simple, the installation is convenient, and the operation and use are very rapid.
