Description

Technical Field

[0001] This application belongs to the field of scraper conveyors, and specifically relates to a tail box and a scraper conveyor on which the tail box is installed. Background Technology

[0002] Scraper conveyors are widely used in coal mines, chemical mines, metal mines, power plants, and smelters due to their simple structure and easy maintenance. The scraper consists of a drive section (head housing), a tail wheel (tail housing), and an intermediate housing (chain and reverse support rail). Material falls into the scraper from the upper grid, and the drive wheel rotates to carry the material into the head discharge device.

[0003] Currently, scraper conveyors have the following drawbacks in operation:

[0004] Material accumulation inside the scraper is difficult to clean: Currently, cleaning the accumulated material inside the scraper tail box mainly involves stopping the scraper conveyor and opening the inspection hole for manual cleaning. However, due to the presence of the scraper chain and tail wheel, the space is small when cleaning the tail accumulation, resulting in long cleaning time and incomplete cleaning. Cleaning personnel cannot remove all the accumulated material in the gap between the tail wheel and the tail baffle of the box. The scraper conveyor is forced to operate in a potentially hazardous environment for extended periods, affecting its operation. Frequent shutdowns for cleaning the tail box waste manpower and reduce the scraper conveyor's operating rate.

[0005] Large pieces of material can easily accumulate at the tail, leading to chain breakage and derailment: Currently, the tail of the scraper uses a closed-type structure with a space. During the production process, large pieces of material are generated. This closed tail wheel box structure can cause material to accumulate at the tail, resulting in scraper chain breakage and derailment.

[0006] To address the aforementioned issues, an innovative design was implemented based on the existing scraper conveyor. Utility Model Content

[0007] This application aims to provide a tail box and a scraper conveyor for installing the tail box, in order to solve the problem of existing scraper conveyors mentioned in the background art: large pieces that fall to the tail wheel during the operation of the scraper conveyor tend to accumulate behind the tail wheel, causing the scraper chain to fall off.

[0008] This application discloses a tail section housing, including:

[0009] A base plate, on which a tail plate and a slide rail are provided, wherein a sliding plate that moves linearly along the slide rail is provided on the slide rail;

[0010] The bearing is mounted on the slide plate;

[0011] An adjusting screw, one end of which is connected to the bearing via a bearing bracket, and the other end of which is connected to the tail plate; and

[0012] The discharge port is located at the tail end of the base plate.

[0013] Preferably, the present application embodiment also discloses that the side wall of the discharge port is provided with an observation hole.

[0014] This application also discloses a scraper conveyor equipped with the aforementioned tail box.

[0015] Compared with the prior art, the device in this application embodiment has a simple structure and is easy to process and manufacture. At the same time, it completely solves the problem of material accumulation between the tail wheel and the tail plate, reduces the scraper chain derailment and chain breakage caused by material accumulation and blockage at the tail of the scraper conveyor. The installation of this device reduces the accumulation of materials at the tail of the machine, reduces the workload of operators, and improves work quality and efficiency.

[0016] The design of the discharge port facilitates continuous material discharge between the tail wheel and the tail plate. Large pieces of material carried to the tail box by the scraper via the return guide rail during operation are directly discharged under gravity, preventing equipment malfunctions due to material accumulation.

[0017] The observation hole on the side wall of the discharge port of this device facilitates daily inspections by staff. It also allows for routine checks on the wear of the tail wheel and the accumulation of material at the tail, ensuring the stable operation of the scraper conveyor. Attached Figure Description

[0021] This application provides a tail box and a scraper conveyor that installs the tail box, which solves the problem in the prior art where large pieces falling to the tail wheel during the operation of the scraper conveyor tend to accumulate behind the tail wheel, causing the scraper chain to fall off.

[0022] The technical solution in this application embodiment is to solve the above-mentioned accumulation problem. The overall idea is as follows: a tail box body, including: a base plate, on which a tail plate and a slide rail are provided, wherein a slide plate that moves linearly along the slide rail is provided; a bearing, which is provided on the slide plate; an adjusting screw, one end of which is connected to the bearing through a bearing bracket, and the other end is connected to the tail plate; and a discharge port, which is provided at the tail end of the base plate.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example

[0024] See appendix Figure 1 A tail section housing includes: a base plate, on which a tail plate and a slide rail are disposed, wherein a sliding plate that moves linearly along the slide rail is disposed on the slide rail; a bearing, the bearing being disposed on the sliding plate; an adjusting screw, one end of which is connected to the bearing via a bearing bracket, and the other end of which is connected to the tail plate, the adjusting screw extending from the tail plate being adjusted to achieve forward and backward adjustment of the tail wheel portion, and to tension the scraper chain; and a discharge port, the discharge port being disposed at the tail end of the base plate, the gap between the tail wheel and the tail plate being filled by adding a discharge port to the base plate, and the discharge port being opened near the tail plate. This reduces the accumulation of material and large pieces between the tail wheel and the tail plate.

[0025] See appendix Figure 1 , 2 The device includes a discharge port to facilitate the discharge of materials and large pieces that fall between the tail wheel and tail plate. An observation hole is added to the side wall of the discharge port for daily inspection of tail wheel wear and the discharge status of materials inside the discharge port.
