Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of buried scraper conveyor, in particular to a low-residual buried scraper conveyor device. BACKGROUND

[0002] The buried scraper conveyor is a continuous conveyor that can transport powder, granular and small block materials in horizontal, inclined or vertical directions by the pushing force of the scraper on the traction member, and is widely used in grain, light industry, chemical industry and other industries.

[0003] The buried scraper conveyor has the characteristics of multi-point feeding and multi-point discharging, and is therefore applied to grain feeding equipment in the warehouse industry. For the multi-outlet buried scraper conveyor, when the middle discharge port is opened and the head discharge port is closed, a small amount of residual material on the chain is brought to the head along with the movement of the scraper chain and accumulates to form head material, which is slowly compacted and filled in the head shell from the middle outlet. When the scraper runs to the head, the scraper is extruded with the material, the material is extruded with the head shell, the extruded material is ground, the breakage rate of the grain is increased, and the safety storage and quality of the grain are affected. When the accumulation of material is serious, part of the material will be extruded from the gap between the head shaft and the two side shells, which seriously affects the service life of the equipment and increases the difficulty of equipment operation and management. When the head shell is provided with a blocking switch, the head material often causes false alarms, and when the head is provided with an observation port, the observation port will also be filled with material, which affects the equipment inspection. When different warehouses store different types of materials, the same scraper machine switches the outlet to enter the warehouse, and the scraper machine accumulates material to form mixed material.

[0004] Material accumulation also often occurs at the tail of the buried scraper conveyor. The tail material is mainly caused by the accumulation of part of the material on the chain at the tail. When the tail shell is square, the residual material is accumulated in the tail, the scraper is extruded with the material, the material is ground, the breakage rate of the grain is increased, the corners of the tail shell are not cleaned for a long time, which is prone to mold and insects, and is not conducive to the safe storage of grain. In particular for the reserve warehouse, after the warehouse is completed, the cleaning line and the conveying line need to be cleaned to remove the residual material in the equipment to avoid breeding pests. If the buried scraper conveyor has a large amount of material accumulation, it will bring a lot of cleaning work to the storage work. Practical new type content
