Embodiment 1

[0020] Feeding hopper 1 is shaped like Figure 1-3 As shown, one side is made to be vertical, and the other side is made to have an angle of 45° with the horizontal plane. The selection basis is that the sliding friction angle is 45° when the moisture content of the crushed straw is about 75%, and the sliding friction angle is less than 45° when the moisture content is less than 75%.

[0021] The feeding hopper 1 is fixed on the feeding place of the screw conveying device with bolts, the rotating shaft 3 is inserted on the feeding hopper 1, and the two ends of the rotating shaft 3 are fixed with the feeding hopper 1 with bearings. Holes are staggered at 90° on the rotation axis 3, and the elastic teeth 2 are welded and fixed in the holes. The significance of the adjacent elastic teeth 2 staggering 90° from each other and fixed on the rotating shaft 3: on the one hand, it can prevent the long crushed straw from winding on the rotating shaft; The baffle plate 4 is connected wi...

Abstract

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.

Description

technical field [0001] The invention relates to the field of agricultural machinery processing and manufacturing, in particular to a feeder for crushing crop straw materials. Background technique [0002] The crushing of straw materials is a processing technology that emerged in my country in the 1980s. Crushed crop straw has many advantages, so its utilization has been widely concerned and valued, and at the same time, research on corresponding mechanical equipment and tools has been promoted. Among them, the screw conveying device is a necessary equipment in the production process of straw utilization. At present, the main problem in the transportation of crushed crop stalks in the screw conveying device is that due to the characteristics of soft, fluffy, irregular size and shape, and poor fluidity of such crushed materials, it is impossible to achieve uniform and continuous feeding. Seriously affect the conveying performance of the conveying device and the post-processi...
