The scraper conveyor 3 transports the mixed materials. The scraper conveyor 3 transports the materials to the belt conveyor 5 through the discharge port at the left end. The belt conveyor 5 transports the materials To transport the materials out, movable connecting material rake mechanisms 4 are arranged on both sides of the walking main beam 2. The power of the walking main beam 2 is on the walking wheels, which cooperate with the walking track 1. The walking wheels move along the walking track 1 to drive the walking main beam 2. The walking main beam 2 drives the rake mechanism to move along the walking track 1. The rake teeth 6 of the rake mechanism loosen the material pile. Under the action of its own gravity, the materials slide to the bottom. The scraper conveyor 3 transports the mixed materials at the bottom to the belt conveyor 5. The materials are transported out through the belt conveyor 5, realizing the function of continuous transportation, avoiding manual unloading on the material pusher, and reducing the labor intensity of manual labor. Belt conveyor is the most important equipment for bulk material transportation and loading and unloading. It can be widely used in mining, metallurgy, building materials, chemical industry, electric power, food processing and other industrial fields. It can be seen in coal mines, metal mines, steel enterprises, ports, cement plants and other places. The conveying machinery can not only complete the transportation of bulk materials, but also transport piece materials. However, according to the different places of use, working environment and types of conveyed materials, there will be great differences in its design and application. Modern conveyor systems have higher requirements for dust prevention. For this reason, water sprinkling and dust collection devices are installed at each transfer point, and wind shields or wind shields are installed along the belt conveyor. The system is composed of single machines. For operators and repairers working in the whole machine system, they must not only base themselves on the single machine they are in charge of, but also understand the mutual connection between systems. The single machine is composed of many parts. Only by doing a good job of daily maintenance of each component and keeping it in good working condition can the safe operation of the equipment be ensured. Belt conveyor is a friction-driven machine that transports materials in a continuous manner. By using it, a material conveying process can be formed from the initial feeding point to the final unloading point on a certain conveying line. It can be used to convey both bulk materials and finished items. In addition to pure material conveying, it can also be coordinated with the requirements of the process in the production process of various industrial enterprises to form a rhythmic flow operation transportation line.

[0025] The material rake comprises a bottom rod 43 and an inclined rod 41, and a plurality of rake teeth 6 are arranged on the bottom rod 43 and the inclined rod 41. The bottom rod 43 is hinged to the walking main beam 2, and the inclined rods 41 are fixedly connected at both ends of the bottom rod 43, and the upper intersection of the inclined rods 41 at both ends is fixedly connected.

The bottom rod 43 is hinged to the walking main beam 2 to realize the left and right swing of the material rake mechanism 4. The inclination of the material rake mechanism 4 is determined according to the slope of the material pile. It has many occasions and a wide range of uses.

[0026] A plurality of evenly distributed connecting rods 42 are provided between the inclined rod 41 and the bottom rod 43, and rake teeth 6 are provided on the connecting rod 42. The connecting rod 42 fills the gap between the inclined rod 41 and the bottom rod 43 to strengthen the strength therebetween. At the same time, rake teeth 6 are also installed on the connecting rod to increase the working area of ​​the rake mechanism, so that the material pile can be loosened more conveniently and quickly, the working efficiency is high, the strength of the material itself is greatly improved, and the service life is longer.

[0027] A fixing frame 7 is provided on the walking beam, and the fixing frame 7 is connected to the connecting rod 42 through a telescopic device 12. The telescopic device 12 on the fixing frame 7 is used to control the inclination of the material rake mechanism 4 and adjust the contact surface depth between the material rake mechanism 4 and the material pile.

[0028] The telescopic device 12 includes a winch 11, a pulley I9 and a pulley II8, the winch is fixed on a fixed frame 7, the pulley I9 is ​​hinged below the winch 11, the pulley II8 is hinged at the upper end of the rake mechanism, the winch 11 is connected to the pulley I9 and the pulley II8 via a steel wire rope 10, the winch 11 is sequentially connected to the pulley 1 and the pulley 2 via the steel wire rope 10, the winch 11 works to retract or unfold the steel wire rope 10, the retraction of the steel wire rope 10 drives the connecting rod 42 of the material rake mechanism 4 to swing, and then drives the entire material rake mechanism 4 to swing, so as to adjust the inclination angle of the material rake mechanism 4 until it is used in conjunction with the existing material pile, that is, the material rake mechanism 4 can loosen the material pile on a large surface.

[0029] The telescopic device 12 is a cylinder or a hydraulic cylinder. The working ends of the cylinder and the hydraulic cylinder are both hinged to the connecting rod 42, and the other ends are hinged to the fixed frame 7. The connecting rod 42 is connected to each other in a mesh between the bottom rod 43 and the inclined rod 41. That is, the telescopic device 12 drives the connecting rod 42 to swing, which can drive the entire material rake mechanism 4 to swing; the cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. Air converts thermal energy into mechanical energy through expansion in the engine cylinder; gas is compressed by the piston in the compressor cylinder to increase the pressure; the hydraulic cylinder is an actuator in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the hydraulic cylinder realizes reciprocating motion. The structural types of hydraulic cylinders are piston cylinders, plunger cylinders, and swing cylinders. The piston cylinder and plunger cylinder realize reciprocating linear motion, output speed and thrust, and the swing cylinder realizes reciprocating swing, output angular velocity (rotation speed) and torque. In addition to being used individually, hydraulic cylinders can also be combined in two or more or in combination with other mechanisms to perform special functions. There are various structural forms of hydraulic cylinders, and there are also many ways to classify them: according to the movement mode, they can be divided into linear reciprocating motion and rotary swinging type; according to the liquid pressure, they can be divided into single-acting type and double-acting type; according to the structural form, they can be divided into piston type, plunger type, multi-stage telescopic sleeve type, gear rack type, etc.; according to the installation form, they can be divided into pull rods, earrings, base feet, hinge shafts, etc.; according to the pressure level, they can be divided into 16Mpa, 25Mpa, 31.5Mpa, etc.

The walking main beam 2 drives the scraper conveyor 3, the fixed frame 7 and the material rake mechanism 4 to move as a whole, and the material pile is loosened by the rake teeth 6 of the material rake mechanism 4, so that the material rolls to the bottom under its own gravity. When the bottom is full of materials, the scraper conveyor 3 transports the materials to the belt conveyor 5, and the materials are transported out through the belt conveyor 5, so as to realize the function of continuous transportation, avoid manual unloading on the material pusher, and reduce the labor intensity of manual labor. The conveyor that uses a scraper chain to transport bulk materials in the trough is called a scraper conveyor. According to the arrangement and structure of the scraper conveyor chute, it can be divided into two types: parallel type and overlapping type. According to the number and arrangement of chains, it can be divided into four types: single chain, double-sided chain, double center chain and triple chain. The adjacent middle trough of the scraper conveyor can be bent to a limited extent in the horizontal and vertical planes. It is called a flexible scraper conveyor. Among them, the working face conveyor with a 90-degree bend at the intersection of the working face and the transport tunnel is called a "corner scraper conveyor". In the current coal mining working face, the role of the scraper conveyor is not only to transport coal and materials, but also the running track of the coal mining machine. Therefore, it has become an indispensable main equipment in the modern coal mining process. The scraper conveyor can maintain continuous operation and production can proceed normally. Otherwise, the entire coal mining working face will be shut down, causing the entire production to be interrupted. The main structure and components of various types of scraper conveyors are basically the same. It consists of three parts: the head, the middle and the tail. In addition, there are also auxiliary components such as hydraulic jack devices for push conveyors and chain tighteners for tightening chains. The head of the machine is composed of a head frame, a motor, a hydraulic coupling, a reducer and a sprocket. The middle part is composed of a transition trough, a middle trough, a chain and a scraper. The tail of the machine is a device for the scraper chain to return.
