further, the spiral groove is of a multi-section structure, the first section of the spiral groove is wound on the outer end face of the guide groove, the edge of the first section of the spiral groove is connected with the inner wall of the cylinder, the two ends of the rear section of the spiral groove are connected with the inner wall of the cylinder, and the multi-section spiral grooves are in seamless connection;
further, the height of one spiral period of the spiral groove is 3500-3600mm;
further, the inclination cheap angle of the spiral groove is 30-40 degrees;
further, the inner diameter of the material guiding cylinder is phi 1000mm;
compared with the prior art, the utility model has the following beneficial effects:
by adopting the utility model, the whole structure is optimized, the whole cost is controlled, the whole processing and manufacturing cost is reduced by adopting a multi-section spiral groove design, the number of spiral sections is selected according to the requirement, the blanking safety of coal bodies is ensured, the poor quality of the coal bodies caused by the falling of the coal bodies is reduced, and the coal blocks are crushed; the overall output quality and efficiency of the mineral products are characterized, the buffering and temporary storage of the materials are integrated, and the equipment cost in the mineral is reduced.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.
Referring to fig. 1-2, a spiral chute for a silo comprises a spiral groove 4, a cylinder 1, a reinforcing upright post 2 and a material guiding post 3; the cylinder body 1 is assembled and installed through a reinforcing upright post 2; the material guide column body 3 is vertically arranged in the upper port of the cylinder body 1, and the external space of the material guide column body 3 is a blanking area; the spiral groove 4 is spirally wound in the cylinder body 1;
furthermore, the spiral groove 4 is of a multi-section structure, the first section of the spiral groove 4 is wound on the outer end face of the material guiding cylinder 3, the edge of the first section of the spiral groove is connected with the inner wall of the cylinder body 1, the two ends of the rear section of the spiral groove 4 are connected with the inner wall of the cylinder body 1, and the multi-section type spiral grooves 4 are in seamless connection; further, the height of one spiral period of the spiral groove 4 is 3570mm; further, the inclination cheap angle of the spiral groove 4 is 35 °; further, the inner diameter of the material guiding column body 2 is phi 1000mm;
in the concrete implementation process of the embodiment, the cylinder body 1 is a temporary storage and buffering space of coal blocks, the space separated by the guide cylinder body 3 at the end is used as a feeding port, the coal blocks are distributed by the guide cylinder body 2 to form smaller material flow, after being guided, the coal blocks are rolled and buffered once along the spiral groove 4, the coal blocks are buffered in a spiral falling manner through the spiral groove 4 of the spiral disc, the height of one spiral rotation period is 3570mm, the gradient of falling is 35 degrees, the whole spiral groove 4 is formed by 5-end spiral periods, the whole height is 17825mm, the coal blocks are ensured to avoid smashing and impacting under the height fall, and the whole coal body product quality is improved.
By adopting the utility model, the whole structure is optimized, the whole cost is controlled, the whole processing and manufacturing cost is reduced by adopting a multi-section spiral groove design, the number of spiral sections is selected according to the requirement, the blanking safety of coal bodies is ensured, the poor quality of the coal bodies caused by the falling of the coal bodies is reduced, and the coal blocks are crushed; the overall output quality and efficiency of the mineral products are characterized, the buffering and temporary storage of the materials are integrated, and the equipment cost in the mineral is reduced.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the scope of the utility model as defined in the accompanying claims.
