Description

Self-moving loader for open-pit mining face

technical field

The utility model relates to a reloading equipment for open-pit mines, in particular to the equipment used for reloading stripped objects or useful minerals on the mining working face of the open-pit mine.

Background technique

At present, when open-pit mines use slag scrapers (scrapers) for mining operations, stripped objects or useful minerals are transported by car, which belongs to intermittent transportation, with low operating efficiency and high production costs.

Contents of the invention

The technical problem to be solved by the utility model is to provide a self-moving loader, which can be used in conjunction with a slag scraper (mine scraper) to realize continuous transportation, improve operating efficiency and reduce production costs.

The purpose of this utility model is achieved in that it includes two belt conveyors, characterized in that: one of them is a material receiving belt conveyor, the other is a discharge belt conveyor, and the discharge belt conveyor The material receiving end is placed under the discharge end of the material receiving belt conveyor, and the material receiving belt conveyor is installed on the support frame with the walking track; a steel structure platform is arranged at the head of the support frame, and the steel structure platform and the T A slewing support is set between the columns of the frame, so that the steel structure platform and the T-frame can rotate relatively. The left end of the T-frame horizontal bar is connected with a C-shaped arm frame, and the right end of the T-shaped frame horizontal bar is connected to one end of the hydraulic cylinder. Hinged, the other end of the hydraulic cylinder is hinged with one end of the V-shaped frame, the other two ends of the V-shaped frame are respectively hinged on the discharge belt conveyor, the upper end of the pull rod arm is fixed on the right end of the T-shaped frame horizontal rod, and the lower end of the pull rod arm On the discharge belt conveyor, the motor (including the reducer) and the driving gear are installed on the C-shaped arm frame. The driving gear meshes with the ring gear. The ring gear is fixed on the steel structure platform. A pulley is installed at the lower end of the C-shaped arm, and the pulley walks along the circular track, that is, the C-shaped arm and the pulley are pushed on the circular track from the bottom of the circular track to reduce the turning force of the slewing bearing. The working process is that the receiving belt conveyor transfers the material to the discharging belt conveyor. During the reloading process, the reciprocating motion of the hydraulic cylinder drives the discharging belt conveyor around the pulling rod arm through the V-shaped frame and the tie rod arm. The pin shaft (which is hinged with the discharge belt conveyor) moves up and down; when the motor is turned forward and reverse, the driving gear reciprocates on the ring gear, and drives the row through the slewing support, T-shaped frame and hydraulic cylinder. The material belt conveyor turns around the center line of the slewing support.

Compared with the prior art, the positive effect of the utility model is that the continuous transportation of stripped objects or useful minerals in the mining face of the slag scraper (miner scraper) is realized, the work efficiency is improved, and the production cost is saved.

Detailed ways

Referring to Fig. 1, it includes two belt conveyors arranged front and back, wherein the rear is a material receiving belt conveyor 1 with a material receiving trough 4, and the front is a discharge belt conveyor 17, the discharge belt conveyor The material-receiving end of conveyor is placed below the reloading chute 19 of the material-receiving belt conveyor discharge end, and the material-receiving belt conveyor is installed on the support frame 2 with the walking crawler belt 3 . Referring to Fig. 2, a steel structure platform 5 is provided at the head of the support frame, and a slewing support 6 is provided between the steel structure platform and the column of the T-shaped frame 7, so that the steel structure platform and the T-shaped frame can rotate relatively, and T The left end of the horizontal bar of the shaped frame is connected with a C-shaped arm frame 8, the right end of the horizontal bar of the T-shaped frame is hinged with one end of the hydraulic cylinder 15, the other end of the hydraulic cylinder is hinged with one end of the V-shaped frame 16, and the other two ends of the V-shaped frame are respectively Hinged on the discharge belt conveyor, the upper end of the pull rod arm 14 is fixed on the right end of the T-shaped frame horizontal bar, and the lower end of the pull rod arm is hinged on the discharge belt conveyor by pin 18. Referring to Fig. 3, the motor 9 and the driving gear 10 are installed on the C-shaped arm frame, and the driving gear meshes with the ring gear 11. Pulley 12 is installed at the lower end, and the pulley walks along the circular track, that is, the C-shaped arm frame and the pulley push against the circular track from below the circular track, so as to reduce the overturning force that the slewing bearing bears. The working process is that the material receiving belt conveyor passes the material through the reloading chute, and then guides the material into the material guide trough 20 of the discharging belt conveyor, and reloads the material through the discharge chute 21 at the discharge end of the discharging belt conveyor. To the next level of equipment; a counterweight 22 is provided on the material receiving belt conveyor to ensure the stable operation of the equipment. During the reloading process, the reciprocating motion of the hydraulic cylinder drives the discharge belt conveyor to move up and down around the pin 18 of the pull rod arm (which is hinged with the discharge belt conveyor) through the V-shaped frame and the tie rod arm; When the motor is turned forward and reverse respectively, the driving gear reciprocates on the ring gear, and drives the discharge belt conveyor to rotate around the center line of the slewing support through the slewing support, T-shaped frame and hydraulic cylinder.
