Technical Field

The invention belongs to the field of mine roadway loading and transporting machinery, and particularly relates to an adjustable bucket mechanism with a coupling of a traction device and a chain drum, which is particularly suitable for roadways with narrow space.

Background

At present, the existing domestic loading and transporting mechanical equipment is huge in size, lack of flexibility when in use, poor in use stability, high in failure rate, strong in dependence of manual technology, low in automation degree and the like, and has potential safety hazards, and the mining progress and the working efficiency of mines are seriously influenced. Therefore, the development of a maneuvering and flexible direction-adjustment-free efficient rock loading machine is urgently needed. The invention realizes the direction-adjusting-free function of the rock loader by the integrated design of the loading and unloading systems, simultaneously optimizes the working spaces of the two systems, and ensures that the working spaces do not influence each other on the premise of occupying the minimum space, thereby being free from the influence of narrow factors of a mining tunnel, completing underground mining tasks, reducing the work required by the work, saving energy, realizing the automatic door opening and closing of a storage door during unloading, accelerating the working efficiency and reducing the dependence on manpower.

Disclosure of Invention

According to the defects in the prior art, the technical problems to be solved by the invention are as follows: aiming at the problems of narrow space in a roadway, limited moving range of a rock loader and the like, a rock loader system integrating loading, transportation and self-unloading is provided to solve the problem that the direction of the rock loader in the roadway is difficult to adjust at present, and the rock loader system can quickly run or keep the best parking position in the narrow roadway due to sensitive operation and small turning radius, so that the working efficiency is obviously improved.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a scraper bowl mechanism with adjustable draw gear and chain drum coupling, includes the frame, its characterized in that: the bucket is installed in frame the place ahead, and the dipper arm and the frame swing joint of bucket are connected with traction system with adjustable on the bucket, and the storage silo is installed to the frame top, still installs cam mechanism and controlling means on the frame.

The bucket system comprises a bucket, a bucket arm and a rotating shaft; the bucket is arranged on the bucket arm; the bucket arm is connected and fixed in the middle of the front end of the rock loader through a rotating shaft; the bucket can be turned around the rotating shaft to fill gangue. The rock loader moves forward, the bucket moves forward under the pushing of the bucket arm, and gangue on the ground is shoveled into the bucket.

The bucket system comprises a bucket chain, a chain drum, a chain wheel and a bucket motor; one end of the bucket chain is fixed on a fixed chain wheel above the bucket, and the other end of the bucket chain is connected with the chain drum through the chain wheel; the chain wheel is arranged above the front part of the rock loader; the chain winding drum and the bucket motor are arranged in the middle of the front part of the rock loader; the bucket motor drives the chain winding drum to rotate, the chain drives the cam transmission system to pull up the bucket through the chain wheel, the bucket turns around the rotating shaft under the action of the bucket arm, single-arm rotation is realized, and gangue in the bucket is cut into the storage bin under the action of inertia; after the bucket motor stalls, the bucket falls by its own weight.

The adjustable traction system comprises a chain wheel, a supporting arm, a cam transmission mechanism and a motor; the chain wheel is fixed on the supporting arm, and the other end of the supporting arm is connected with the cam transmission device and is arranged in the slideway at the upper end of the front part of the frame; the cam transmission mechanism is powered by a motor to rotate; the cam transmission device is driven by the bucket motor to enable the chain wheel supporting arm to stretch and reciprocate in the slideway.

The storage bin comprises a carriage, a car door pin shaft, a bin door, a tipping bucket oil cylinder, a tipping bucket pin shaft, a fixed pin and a door stop iron strip; the carriage is arranged on the upper part of the frame through a tipping bucket pin shaft; the bin gate is arranged at the upper rear part of the carriage through a car door pin shaft; the tipping bucket oil cylinder is positioned at the front lower part of the carriage frame; one fixing pin is fixed on the side surface of the carriage, and the other fixing pin is fixed on a rock loading locomotive bed frame and is connected with the granary door through a chain; when the rock loader unloads the gangue, the carriage is pushed by the skip bucket oil cylinder to upwards turn up around the skip bucket pin shaft, at the moment, the fixing pin on the side surface of the storage bin starts to rise along with the carriage, the bin door is pulled by the chain to turn over around the car door pin shaft, and the car door is opened to unload the gangue; when the storage silo returns to the horizontal state, the silo door is closed under the action of self gravity, and the door stop iron strip can prevent the silo door from being opened when the storage silo is horizontally filled with gangue.

The innovation points of the invention are as follows: the utility model provides a dress carries defeated uninstallation rock loader as an organic whole of collection dress, the function of exempting from to transfer of rock loader has been realized, draw gear with adjustable has optimized the working space of system, make it do not influence each other taking up under the minimum space prerequisite, and the work of having practiced thrift rock loader upset waste rock to a certain extent has reduced the burden of scraper bowl and chain, resources are saved prolongs rock loader life simultaneously, the design of single dipper arm has reduced rock loader's self weight, rock loader overall structure is compact, small, consequently, can not receive the influence of the narrow and small factor of exploitation gallery. Compared with the prior rock loader, the novel rock loader further optimizes the loading of the gangue, thoroughly realizes that the loading and unloading of the gangue are not interfered with each other, and maximizes the working space; the storage bin is optimized, so that the bin door is completely and automatically opened and closed, and the unloading efficiency of the gangue is greatly improved.
