Description

Technical Field

[0001] The utility model relates to the technical field of plate type feeders, in particular to a fully enclosed protective cover device for plate type feeders. Background Art

[0002] Plate feeder belongs to the category of conveying equipment and is a type of conveying equipment. Plate feeder can be divided into heavy-duty and light-duty. Plate feeder is an indispensable equipment in raw material processing or continuous production process, and is particularly suitable for conveying large and sharp materials. Plate feeder consists of five parts: head drive device, tail device, chain plate device, tail tensioning device and frame. Plate feeder uses the power of the motor to drive the sprocket shaft to rotate through the coupling and reducer, and the sprocket teeth mesh with the chain pin shaft to drag the chain plate for continuous linear movement. The chain plate is supported by the supporting wheels and sprockets installed on the frame, and the tensioning device is adjusted to make the chain and sprocket properly meshed to complete the feeding. The existing plate feeder will generate a lot of dust when transporting limestone, which will affect the environment. In addition, after the plate feeder transports limestone, a small amount of limestone powder will fall on the lower part of the plate feeder, so workers are required to clean it regularly. The lower part of the plate feeder is relatively closed and not convenient for workers to enter, so more equipment needs to be disassembled and assembled during cleaning, which increases the difficulty of construction.

[0024] Working principle:

[0025] When the utility model is in use, firstly, the protective cover 3 is fixed to the outer wall of the plate feeder 1 by bolts, so that the plate feeder 1 can avoid the leakage of dust when transporting limestone. When the limestone powder falls on the bottom end of the support body 2 after transportation, the drive motor 62 is started to drive the reciprocating screw 61 to rotate. At this time, the slider 65 is driven by the reciprocating screw 61 to reciprocate along the inner wall of the support body 2. At the same time, the scraper 5 is driven to reciprocate. When the slider 65 is located at the inner wall of the bottom end of the annular groove 63, the scraper 5 drives the scraper 11 to remove the dust at the bottom end of the support body 2. When the slider 65 moves to one side of the annular groove 63, the top block 10 starts to slide along the slope 64, so that the top block 10 drives the slide plate 9 to squeeze the limit spring 8. At this time, the reciprocating screw 61 drives the scraper 5 to move upward, so that the scraper 11 does not contact the bottom end of the support body 2.
