Tramcar automatic feeding device used for wet pulp shooting machine

Abstract

The invention discloses a tramcar automatic feeding device used for a wet pulp shooting machine. A belt type conveying rack is mounted on the front portion of a rack. A funnel opening is located abovea belt of a belt conveyor. A left guide rail and a right guide rail are erected on the belt type conveying rack and located behind a funnel. Roller wheels on the two sides of a conveying frame are arranged in corresponding guide roller grooves of the left guide rail and the right guide rail correspondingly and do back and forth movement along the left guide rail and the right guide rail under traction of a traction mechanism to convey and feed a tramcar. Materials are dumped through automatic turnover. The device is simple in structure and stable and reliable in operation. Forward and reverserotation of a roller is controlled through a motor to achieve feed; operation is simple; the problems about manual feed of the wet pulp shooting machine are solved; the automatic feed efficiency is high; little power is needed; the work efficiency is greatly improved; the labor intensity is reduced; the body health of workers is guaranteed; and therefore manual hidden danger is eliminated.

Description

technical field [0001] The invention relates to a mine car feeding device, in particular to a mine car automatic feeding device used for a wet shotcrete machine. Background technique [0002] The shotcrete support technology has not only become the main form of rock shaft support in mines, but also a widely used lining technology in the fields of transportation, water conservancy, and urban subways. However, in this process, due to the lack of suitable mechanical equipment, the main It is manually fed to the injection machine, which has high labor intensity and low work efficiency. [0003] On the other hand, due to the scattered underground excavation surfaces and narrow roadway space, ground mixing stations are often used to prepare dry-mixed aggregates during infrastructure construction, and then transported to each excavation surface by mine trucks.

Problems solved by technology

[0002] The shotcrete support technology has not only become the main form of rock shaft support in mines, but also a widely used lining technology in the fields of transportation, water conservancy, and urban subways. However, in this process, due to the lack of suitable mechanical equipment, the main It is manually fed to the injection machine, which is labor-intensive and low-efficiency

[0003] On the other hand, due to the scattered underground excavation surfaces and narrow roadway space, ground mixing stations are often used to prepare dry-mixed aggregates during infrastructure construction, and then transported to each excavation surface by mine trucks. Since the excavation surface is usually far away from the shaft, the ground The configured aggregate will be solidified in advance during frequent transportation. When using it, it must be manually mixed on site, which is laborious and time-consuming, which seriously affects the speed of support construction and the quality of spraying.

For this reason, researchers have developed several models such as chain bucket feeding machine, negative pressure suction machine, and wet spray extrusion pump, but they have not been successfully applied due to complex structures, inconvenient use, pigging or transportation difficulties.

[0004] The Chinese patent "An Automatic Feeding Shotcrete Machine for Coal Mine" (publication number CN200920270907.4, publication date 2009.12.01) discloses an automatic feeding shotcrete machine for coal mines, including a shotcrete machine, lifting cylinder, traction The disadvantage of the motor, scraper chain and mine car is that the scraper chain needs to be put into the mine car, which is cumbersome to operate and will cause some residues in the material transportation of the mine car.
