[0022] like Figure 1-4 As shown, the first aspect of the embodiment of the present disclosure provides a split type waste rock thrower for mining, which includes a main frame 1, a traveling mechanism 2, a receiving part 3, a conveying part 4, a projectile system 5 and a control system 6. The traveling mechanism 2 includes left and right crawler traveling devices and a crawler cover, and the main frame 1 is fixedly connected to the crawler cover. The design of the traveling mechanism 2 enables the waste rock thrower to move stably in a complex mine environment, thereby improving the maneuverability and operating range of the equipment. The design of the left and right crawler traveling devices and the crawler cover enables the machine to maintain good traction and stability even on uneven ground, thereby reducing the situation where operations are affected by ground conditions. The control system 6 includes a hydraulic system such as a fuel tank, a pump station, a hydraulic valve, and a remote control, a signal receiver, a central controller electronic control system, and the like.

[0023] The conveying part 4 and the ejection system 5 are connected in sequence to form a channel for the movement of gangue; along the moving direction of the gangue, the conveying part 4 gradually tilts upward; the ejection system 5 is installed on the main frame 1 in a manner that it can swing up and down and left and right; the conveying rate of the ejection system 5 is greater than the conveying rate of the conveying part 4, thereby ejecting the gangue.

[0024] The split-type gangue thrower for mining is designed as a split structure according to the needs of tunnel filling, and the gangue filling is divided into two stages: first, a large amount of gangue is lifted to a specified height by the conveying part 4, and then the gangue is quickly ejected by the fast transportation speed of the ejection system 5. At the same time, the split ejection system 5 can rotate and pitch relative to the conveying part 4 to control the ejection height, ejection angle, and ejection speed, so that the gangue is ejected without dead angles, and the tunnel filling task can be better completed. The problem that the integrated gangue thrower needs to constantly adjust the orientation of the whole machine during the ejection process, resulting in low efficiency and poor filling effect, is solved, and the equipment's adaptability to tunnels is further improved.

[0025] As an optional embodiment, the rock thrower further comprises a slewing support device 1.3 and a first lifting cylinder 1.4 mounted on the main frame 1; the ejection system 5 is hingedly mounted on the slewing support device 1.3; one end of the first lifting cylinder 1.4 is hingedly connected to the main frame 1; and the other end of the first lifting cylinder 1.4 is hingedly connected to the ejection system 5. The slewing support device 1.3 enables the ejection system 5 to rotate 360 ​​degrees relative to the main frame 1, which greatly enhances the adaptability of the machine to different working environments and allows the ejection direction to be adjusted without moving the entire machine; the setting of the first lifting cylinder 1.4 enables the ejection system 5 to perform vertical lifting movement, which allows the height of the ejection system 5 to be adjusted according to the working requirements to adapt to different ejection height requirements; the vertical support provided by the first lifting cylinder 1.4 and the horizontal rotation ability of the slewing support device 1.3 work together to improve the stability of the machine during ejection operations, reduce vibration and movement during the operation, and thus improve the reliability of the operation and the durability of the machine.

[0026] As an optional embodiment, the ejection system 5 includes an ejection frame and a driving motor, a driving roller 5.2, a front redirecting roller 5.7, a rear redirecting roller 5.8 and a belt installed on the ejection frame; the front redirecting roller 5.7 is located at the front end of the ejection frame, and the rear redirecting roller 5.8 is located at the rear end of the ejection frame; the belt is arranged around the ejection frame and cooperates with the driving roller 5.2, the front redirecting roller 5.7 and the rear redirecting roller 5.8 by friction transmission, and the driving motor is used to drive the driving roller 5.2 to rotate to drive the belt to move. The design of the ejection system 5 enables the belt to move the gangue quickly. This high-speed belt transmission system can eject a large amount of gangue to a distant place in a short time, thereby improving the working efficiency of the gangue thrower. At the same time, the friction transmission of the belt reduces energy loss and improves energy utilization efficiency.

[0027] As an optional embodiment, the ejection frame includes a tail portion 5.1 and a rigid frame 5.3 that are fixedly connected to each other; the drive motor, the drive roller 5.2 and the rear redirection roller 5.8 are all installed on the tail portion 5.1; the front redirection roller 5.7 is installed on the rigid frame 5.3; the tail portion 5.1 is also provided with a plurality of buffer rollers 5.9 distributed at intervals; the rigid frame 5.3 is also provided with a plurality of idler rollers 5.4 distributed at intervals. The design of the ejection frame enhances the stability and carrying capacity of the entire ejection system 5. The fixed connection between the tail portion 5.1 and the rigid frame 5.3 and the interval distribution of the buffer rollers 5.9 and the idler rollers 5.4 reduce the impact of the material on the frame during high-speed movement and extend the service life of the machine.

[0028] As an optional embodiment, the ejection system 5 also includes a baffle 5.5 and a second lifting cylinder 5.6; the baffle 5.5 is hinged to the front end of the ejection frame; one end of the second lifting cylinder 5.6 is hinged to the ejection frame, and the other end of the second lifting cylinder 5.6 is hinged to the baffle 5.5.

The scraper chain has strong conveying power and adjustable conveying speed, and can lift a large amount of gangue to a specified height; the design of the conveying part 4 enables the gangue to be effectively transported to the ejection system 5, thereby improving the continuity and efficiency of the entire gangue ejection process. The design of the driving member 4.4 and the scraper chain assembly 4.6 reduces the stagnation and accumulation of materials during the conveying process, and ensures the smooth transportation of materials.

[0032] As an optional embodiment, the conveying part 4 also includes a split sprocket shaft assembly 4.5, a tensioning cylinder 4.2 and a tensioning member 4.3 installed on the conveying frame; the split sprocket shaft assembly 4.5 is movably arranged at the front end of the conveying trough 4.1 and connected to the scraper chain assembly 4.6; the tensioning member 4.3 is connected and arranged between the split sprocket shaft assembly 4.5 and the tensioning cylinder 4.2; the tensioning cylinder 4.2 drives the split sprocket shaft assembly 4.5 to move through the tensioning member 4.3 to adjust the tension of the scraper chain assembly 4.6. The design of the split sprocket shaft assembly 4.5, the tensioning cylinder 4.2 and the tensioning member 4.3 allows the tension of the scraper chain assembly 4.6 to be adjusted according to actual needs, ensuring the stability and reliability of the conveying process. This design reduces the failure of the chain caused by being too loose or too tight, and improves the working efficiency and safety of the conveying system.
