Description

Technical Field

[0001] The utility model relates to the technical field of sand conveying devices, in particular to a sand conveying device for a sand screening system. Background Art

[0002] Sand is one of the commonly used raw materials in the construction industry. It can be mixed with water, cement and other additives to make concrete. Concrete is widely used in construction and infrastructure projects, such as building houses, bridges, roads and dams. Sand is one of the main raw materials for glassmaking. The silicon element in sand is an important ingredient necessary for making glass.

[0003] Sand delivery is an important part of the sand screening system. The application of the sand delivery device effectively improves the sand screening efficiency of the sand screening system, making the sand screening more thorough, while reducing the labor intensity of manual sand shoveling and improving work efficiency. This device has broad application prospects in the fields of construction engineering, road construction, etc.

[0004] The prior art patent document with publication number CN209720531U provides a sand conveying device for a sand screening system. When sand and gravel accumulate at the discharge port and cause the discharge port to be blocked, the transmission component can be used to drive the telescopic push rod to reciprocate, so that the telescopic push rod can push away the sand and gravel accumulated at the discharge port, thereby reducing the friction between the sand and gravel and the inner wall of the discharge bin. Moreover, since the connecting hole is inclined downward from the outer wall of the discharge bin to the inner wall of the discharge bin, the telescopic push rod is extended into the discharge bin to push away the sand and gravel, and at the same time, a downward force is generated on the sand and gravel, so that under the combined action of the force of the push rod on the sand and gravel and the gravity of the sand and gravel themselves, the sand and gravel can be smoothly discharged from the discharge port.

[0005] In the above-mentioned prior art, although the device can drive the reciprocating motion of the telescopic push rod in the discharge bin through the transmission component to push the sand at the discharge port open, thus avoiding the accumulation of sand at the discharge port and causing blockage, the sand feeding device in the patented technology cannot automatically screen the sand and gravel with larger particles when in use, and manual screening of the sand is required. In addition, the size of the sand particles required to be used in different situations will also be different. Therefore, the sand feeding device cannot screen the sand when in use, and the quality of the raw materials may be affected easily due to the excessive size of the sand and gravel. Therefore, we need a sand feeding device for a sand screening system. Utility Model Content
