Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sand-lifting devices, and more specifically, to an anti-clogging circulating lifting bucket sand-lifting device. Background Technology
[0002] Bucket elevators are continuous conveying machines that use a series of buckets uniformly fixed to an endless traction component to vertically lift materials. Bucket elevators use a series of buckets fixed to a traction chain or belt to transport bulk materials upward in a vertical or near-vertical direction.
[0003] Traditional sand feeding devices use a spiral feeding method inside the pipe. However, the friction between the spiral sand feeding device and the pipe wall during the feeding process causes the sand between the spiral sand feeding device and the pipe wall to be ground up, resulting in dust. The uneven sand particles will seriously affect the quality of the product, pollute the working environment, and also have a certain impact on the health of workers.
[0004] A search revealed that Chinese patent CN209889884U discloses a bucket elevator-type sand conveying device. This device prevents dust generated when sand enters the hopper from spreading to the surrounding environment and prevents the sand from being crushed during transportation. It also prevents damage to the instrument caused by vibration during operation. At the same time, the device is easy to install and disassemble, and its stability and safety are enhanced.
[0005] In actual use, the sand in the bucket elevator sand feeding device mentioned above may contain large stones or impurities. These large stones may get stuck together during the rolling process, causing blockage inside the feed box. This will slow down or even stop the feeding speed, affecting the normal feeding of sand and thus reducing the overall production efficiency. Utility Model Content

An electric push rod is fixedly connected to one side of the bucket elevator, and a connecting frame is fixedly connected to the output end of the electric push rod. A connecting block is fixedly connected to one end of the connecting frame, and a fixing plate is fixedly connected to the bottom end of the connecting block. A connecting shell is provided on the outer side of the fixing plate, and the connecting shell is fixedly connected to one side of the feeding box.

A filter screen is fixedly connected to one side of the fixing plate, and the filter screen is slidably connected to the inner side of the feeding box. A discharge port is connected to one side of the bucket elevator.
[0010] By adopting the above technical solution, the content of large-particle stones and impurities in sand can be reduced, preventing the risk of blockage caused by large-particle impurities during transportation.
[0011] As a further description of the above technical solution: the crushing structure includes a variable frequency motor, which is fixedly connected to one side of the feed box. Two second inclined plates are fixedly connected inside the feed box, and a first inclined plate is fixedly connected inside the feed box. A second gear is fixedly connected to the output end of the variable frequency motor. A third gear meshes with one side of the second gear. Rotating rods are fixedly connected to the inner sides of both the second and third gears. Multiple first crushing bars are fixedly connected to the outer sides of the rotating rods. Crushing blades are fixedly connected to the outer sides of both rotating rods. A second crushing bar is fixedly connected to one end of each crushing blade.
[0012] By adopting the above technical solution, it is possible to maintain the uniform fineness of the sand and reduce the clumping of sand.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. By setting up a screening component, compared with the existing technology, the spiral action of the spiral blades can quickly guide the sand to flow downwards, and the reciprocating oscillating filter screen can screen out large particles of stones in the sand, which can reduce the blockage caused by large particles of stones or impurities inside the feed box, reduce the risk of blockage, and thus improve the efficiency of sand feeding and conveying.
[0015] 2.
