The tunnel mucking machine can be powered by oil or electricity, consisting of four key components: the slag scraper, power traction device, transportation guide rail seat, pipeline suspension device, etc.China Coal mucking rock loader factory in Shandong is specialized in producing various kinds of mucking rock loader and ore raking machines. The price of slag raking machines is also economical and affordable. The main products are coal mine slag raking machines, small slag raking machines, crawler and wheel tunnel mucking machine.
The power traction device for mini mucking loader is mainly composed of a regular diesel engine or electric motor, which is powered by diesel to output power, transmitted to the gearbox, or output to the air pump, providing power for slag scraping, walking, and transportation of the entire vehicle.
The slag scraping shovel of the mucking rock loader is composed of a trolley bracket, a rotating structure, a clamping arm mechanism, an upper and lower lifting arm mechanism, a slag scraping rod, and a slag scraping shovel. The walking trolley bracket is a frame welded with steel sections, equipped with 4 walking wheels and 4 guide wheels respectively. The upper part is equipped with a rotating device, which is pulled by a traction device and moves forward and backward within the guide rail.
A rotating mechanism is composed of a series connected cylinder, a damping cylinder, and a rotating body. The series cylinder and damping cylinder are installed on both sides of the rotating body, driven by the series cylinder, and the damping cylinder brakes to achieve the left and right rotation movement of the slag scraping rod. The clamping arm mechanism is composed of a clamping arm cylinder and a set of crank connecting rod mechanisms, which can enhance the stiffness of the slag removal rod and be more conducive to slag removal.
The upper and lower lifting arm mechanism is composed of an upper and lower cylinder, a worm gear jack, two sets of plate springs, and some connecting rods. It is pulled by the elastic force of the plate springs to meet the design requirements of the height of the suspended slag removal rod. The upper and lower cylinders drive the connecting rods and springs to achieve the process of the slag removal rod moving up and down. The worm gear jack is driven by an electric motor, and the force arm distance between the upper and lower lifting arms is adjusted by the worm gear transmission pair to achieve different initial height positions of the scraper.
The guide rail base of the mucking rock loader is composed of a set of mini mucking loader car guide rails, a set of moving pulley car guide rails, and a base welded with steel. This base not only needs to install two sets of guide rails, but also the pulley group in the traction device, the walking large cylinder, and the compressed air tank. The base occupies a relatively large area, about 3.5 x 10 mZ, and has good stability.
The pipeline suspension device is composed of two rotating suspension rods fixed on the ground and two rotating suspension rods fixed on the mucking rock loader, which hang the cable pipeline and compressed air pipeline to ensure that the tunnel mucking machine is not affected during forward and backward movement.
