[0002] At present, in the paper and wood-based panel industry, the quality requirements for finished paper and wood-based panel products are increasing day by day, which also makes the quality requirements for raw materials (wood chips) more stringent. In the process of processing wood chips before entering the pulp, the wood chips need to be screened to ensure the quality of the final product. The traditional processing process usually transports the wood chips to the screening mechanism separately through a balance bin and a conveyor, which takes up a lot of space, has low efficiency and high cost.

[0003] Therefore, the utility model provides a spiral discharger to solve the problems raised in the above background technology. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a spiral discharger with high automation and high working efficiency.

[0005] According to the first embodiment of the utility model, the spiral discharger comprises a trough body, a spiral main shaft is rotatably arranged in the trough body, and a plurality of spiral blades are arranged on the spiral main shaft along the radial direction; the trough body is a special-shaped structure, one end of which is close to the spiral blades and the other end is far away from the spiral blades, and the upper part of the trough body is open to form a feed inlet;

[0006] A semi-enclosed space is formed between the trough body and the spiral blades.

[0007] The spiral unloader according to the embodiment of the utility model has at least the following beneficial effects:

[0008] The wood chips fall from the material dividing screw into the semi-enclosed space formed by the spiral blades and the trough body. During the rotation of the spiral main shaft, the spiral blades are driven to rotate the wood chips in the spiral blades. At the same time, the special-shaped trough body squeezes the wood chips so that the amount of wood chips rotated by the spiral blades is precisely controlled. As the wood chips rotate, they are discharged when passing through the discharge port, which improves the processing efficiency.

[0009] According to some embodiments of the utility model, the two ends of the trough body are fixed with end plates by bolts, at least one end plate is provided with a motor, and the output end of the motor is connected to the spiral main shaft. When working, the motor rotates through the connection to rotate the spiral main shaft, so that the spiral blades work, thereby improving the degree of automation.

[0010] According to some embodiments of the utility model, the spiral main shaft is rotatably connected to both ends of the trough body through a bearing seat. When the spiral main shaft rotates, the bearing seat can limit the radial movement of the spiral main shaft, thereby improving the transmission stability.

[0011] According to some embodiments of the utility model, the lower part of the trough body is opened to form a discharge port, which is convenient for taking out materials.

[0012] According to some embodiments of the utility model, baffles are provided on both edges of the upper part of the trough body, and the baffles are used to block the gaps at both ends of the trough body to prevent wood chips from falling directly into the gaps and avoid material jamming.

[0013] According to some embodiments of the utility model, the spiral discharger is installed at the bottom of the material dividing screw machine through the feed port, and the feed port is directly connected to the material dividing screw machine, so that the wood chips can fill the feed port when they reach the material dividing screw machine.

[0014] According to some embodiments of the utility model, the pitch of the spiral blades is ≥400 mm, so that enough wood chips can be accommodated between the spiral blades, thereby improving work efficiency.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
