Description

Technical Field

[0001] The utility model relates to the field of feeding equipment, in particular to a hopper of a quartz sand hopper type feeding device. Background Art

[0002] Quartz sand is quartz particles made by crushing quartz stone, and is an important industrial mineral raw material; the bucket loading device is used to transport quartz sand and other materials from the storage bin or raw material pile to the processing equipment or transportation tools to achieve continuous supply of materials;

[0003] When a bucket-type loading device is used to load quartz sand, a motor drives a bucket chain or a conveyor belt to transmit power to the bucket, causing it to rise or fall along a vertical or inclined track; when the bucket is at the bottom, the material is loaded into the bucket from the feed gate, and as the motor drives the bucket to be lifted to the target position, and then the material is unloaded from the bucket by tipping the bucket as it descends; when a bucket-type loading device is used to load quartz sand, the quartz sand absorbs moisture and becomes sticky when exposed to the air, causing the quartz sand to remain on the inner wall of the bucket during unloading. As loading proceeds, the sand and gravel remaining on the inner wall of the bucket will increase with the number of uses, causing the space in the bucket to be affected and reduced. If the inner wall of the hopper needs to be cleaned, it can only be cleaned manually one by one, which is time-consuming and labor-intensive, and affects the efficiency of loading.

[0016] A scraper 5 is vertically downwardly provided in the arc groove, and the scraper 5 is a rectangular plate body. The lower end of the scraper 5 is close to the lower end of the arc plate 2, and a rotating shaft 4 is installed on the upper end of the scraper 5. The front and rear ends of the rotating shaft 4 are respectively movably passed through the baffle 3 on the same side, and the front and rear ends of the rotating shaft 4 are respectively vertically downwardly provided with connecting rods 6, and a counterweight rod 7 is fixedly connected between the lower ends of the two connecting rods 6. The counterweight rod 7 is located at the bottom of the accommodating cavity and corresponds to the scraper 5 above and below.

[0017] The baffle plate 3 is a fan-shaped plate, the vertical surface of the baffle plate 3 is fixedly connected to the inner wall of the shell 1 , and the top surface of the baffle plate 3 is flush with the top surface of the shell 1 .

[0018] The lower end of the scraper 5 is fixedly connected with a triangular prism 10 with the tip facing downward.

[0019] The front and rear surfaces of the scraper 5 are in sliding contact with the inner side surfaces of the two baffles 3 , and the tip of the triangular prism 10 is in sliding contact with the inner side surface of the arc plate 2 .

[0021] The upper opening of the accommodating cavity is sealed with a cover plate 8, and the cover plate 8 is a circular plate body.

[0022] A triangular prism 11 with a tip facing upward is disposed on the top surface of the cover plate 8 located between the upper end of the arc-shaped plate 2 and the inner wall of the housing 1 .

[0023] The arc plate 2 is an arc plate body with the rotating shaft 4 as the center, and the center angle of the arc plate 2 is greater than 90 degrees.

The quartz sand adhering to the inner wall of the bucket is scraped off, and the quartz sand on the opposite surfaces of the two baffles 3 is scraped off by the front and rear ends of the scraper 5, and the protrusions arranged on the scraper 5 will make it difficult for the quartz sand to adhere to the scraper 5. Then, as the bucket-type feeding device continues to operate, when the bucket is transferred from a descending state to an ascending state, the counterweight rod 7 swings back under the influence of gravity, so that the scraper 5 gradually returns to its original position, and such a reciprocating cycle is repeated. The utility model solves the problem that quartz sand is easily left on the inner wall of the hopper, resulting in a reduction in the space in the hopper and affecting the feeding efficiency.
