Description

Technical Field

[0001] The utility model relates to the technical field of coal unloaders, in particular to a sealing and fixing component of a coal unloader. Background Art

[0002] A coal unloader is a device used to unload coal from transportation equipment. It transfers coal through components such as mechanical devices, transmission systems and conveyor belts. The function of a coal unloader is to improve the efficiency of coal unloading, reduce labor intensity, and ensure the safety of coal during unloading.

[0003] The color steel tile cover on the top of the coal unloader is a structure covering the top of the coal unloader, which is composed of multiple pieces of color steel tiles connected together. The function of the color steel tile cover on the top of the coal unloader is to prevent the coal from escaping during the unloading process to reduce the dispersion of coal powder and protect the cleanliness and safety of the surrounding environment. However, there are gaps between the multiple pieces of color steel tiles, which causes coal fragments or dust to escape, affecting environmental hygiene and workplace safety. In addition, the fixedly installed color steel tiles block the upper end of the coal unloader during maintenance, making the maintenance of the coal unloader very inconvenient. For this reason, we propose a coal unloader sealing and fixing component to solve the existing problems. Utility Model Content

The motor drives the transmission wheel to rotate, the transmission wheel is linked to the belt to rotate, the counter-rotating rollers are linked, and the conveyor belt is rotated by the friction of the rollers.

[0008] Preferably, the two ends of the slide bar are provided with support feet, and the support feet are connected to the machine body, and the sleeve ring is slidably sleeved on the outer wall of the slide bar. The slide bar is fixed at both ends of the machine body, and there is a gap between the slide bar and the machine body to ensure the passage of the sleeve.

When the bolt rotates and drives the pressure block to fit the slide rod, the rotational force acts on the bearing, and the stroke force acts on the pressure block.

[0010] Preferably, the travel plate is provided with a triangular plate at one opposite end, and the triangular plate cone portion is opposite to the second dust blocking cloth. The triangular plate cone portion exerts a squeezing force on the second dust blocking cloth to squeeze and tighten the fitting surface.

[0011] Preferably, one end of the hydraulic rod is connected to the travel plate. The hydraulic rod drives the travel plate to move laterally.

[0012] Preferably, the outer wall of the adjusting bolt is provided with a torsion block. The torsion block is rotated to apply force to the screw rod, and the torsion block is used for a user to grasp and apply force.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model removes the color steel tiles and replaces them with ash blocking cloths. The ash blocking cloths are supported by a plurality of arc rods. The arc rods slide above the coal unloader and are fixed by adjusting bolts. The unfolded ash blocking cloths intercept the coal transported by the coal unloader. The lower end of the ash blocking cloth is connected to the second ash blocking cloth to shield the sliding installation of the sliding sleeve. The ash blocking cloths are pressed on the outer walls of both sides of the machine body through the travel plate to avoid the problem of coal ash leakage through the gaps in the color steel tiles during the transportation process. The dust suppression equipment can be easily stored, which provides convenience for the maintenance of the coal unloader. BRIEF DESCRIPTION OF THE DRAWINGS
