[0043] With the continuous improvement of the degree of mechanization in mines, some operations in dangerous and harsh underground mine environments are gradually replaced by mechanical equipment. For the ore-discharging process in underground mines, when blocking the ore-discharging port, it is still mostly done manually using wooden boards to block, which has significant safety hazards. Moreover, during ore discharging, due to the inertial effect of ore spilling, some ore deviates from the lower ore car hopper, causing ore to spill and resulting in economic losses.
[0044] To solve the technical problems in the prior art that when manually using wooden boards to block the ore-discharging port, there are significant safety hazards, and during ore discharging, due to the inertial effect of ore spilling, some ore deviates from the lower ore car hopper, causing ore to spill and resulting in economic losses, this application provides an automatic device for blocking ore spillage. Among them, the material blocking hopper is driven by an electric push rod to close the discharge port, thereby achieving the technical effect of effectively blocking the spillage of material stones.
[0045] Please refer to Figure 1 which is a schematic structural diagram of an automatic ore spillage blocking device provided for the embodiments of the present application, including a fixed seat 1, an electric push rod 3, a push rod bracket 2, and a material retaining hopper 4. Among them, the push rod bracket 2 is arranged on the fixed seat 1, one end of the push rod bracket 2 is hinged to the fixed seat 1, the material retaining hopper 4 is arranged at the other end of the push rod bracket 2, the fixed end of the electric push rod 3 is fixedly connected to the fixed seat 1, and the telescopic end of the electric push rod 3 is slidably connected to the push rod bracket 2. During use, the electric push rod 3 drives the push rod bracket 2 to rotate, thereby driving the material retaining hopper 4 to move. In this embodiment, the electric push rod 3 drives the material retaining hopper 4 to close the discharge port, thereby effectively blocking the ore from spilling.
[0046] In the embodiments of the present application, as Figures 2 - 3 shown, the automatic ore spillage blocking device is fixed on one side of the ore discharging machine. When the ore discharging machine is in the non-working ore discharging state, the telescopic end of the electric push rod 3 is driven to extend. At this time, the telescopic end of the electric push rod 3 drives the material retaining hopper 4 to move towards the discharge port of the ore discharging machine through the push rod bracket 2 and blocks the discharge port of the ore discharging machine, effectively preventing the ore in the ore discharging machine from spilling out; when the ore discharging machine is in the working ore discharging state, the telescopic end of the electric push rod 3 is driven to retract. At this time, the telescopic end of the electric push rod 3 drives the material retaining hopper 4 to move away from the discharge port of the ore discharging machine through the push rod bracket 2, so that the ore in the ore discharging machine can be conveyed from the discharge port to the ore cart below the ore discharging machine.
[0047] Secondly, in this embodiment, after the telescopic end of the electric push rod 3 drives the material retaining hopper 4 to move away from the discharge port of the ore discharging machine through the push rod bracket 2, the material retaining hopper 4 can be controlled to be close to the ore cart below the ore discharging machine. At this time, the material retaining hopper 4 is located above the ore cart and is used as a blocking member for the side wall of the ore cart, effectively blocking the ore in the ore cart from spilling out of the ore cart when the discharge port of the ore discharging machine conveys ore into the ore cart.
[0048] In this embodiment, the material retaining hopper 4 includes a first baffle 41, a second baffle 42, and a third baffle 43. The first baffle 41, the second baffle 42, and the third baffle 43 are connected end to end in sequence and form a "U" - shaped structure. The other end of the push rod bracket 2 is connected to the second baffle 42. After the telescopic end of the electric push rod 3 drives the material retaining hopper 4 to move away from the discharge port of the ore discharging machine through the push rod bracket 2, the "U" - shaped material retaining hopper 4 can simultaneously block the left, right, and front directions of the ore cart, thereby more effectively blocking the ore in the ore cart from spilling out of the ore cart.

Secondly, in this embodiment, the sliding block 23 is arranged between the first bracket 21 and the second bracket 22 and is slidably connected to the first bracket 21 and the second bracket 22. The telescopic end of the electric push rod 3 is hinged to the sliding block 23. When driving the telescopic end of the electric push rod 3 to expand and contract, the electric push rod 3 drives the sliding block 23 to slide, thereby changing the inclination angle of the push rod bracket 2.
[0050] In this embodiment, chutes are provided on both sides of the sliding block 23, and balls are provided on the inner side walls of the chutes. The first bracket 21 and the second bracket 22 are placed in the chutes and are in contact with the balls. The sliding block 23 contacts the first bracket 21 and the second bracket 22 through the balls in the chutes, enabling the sliding block 23 to slide more smoothly on the first bracket 21 and the second bracket 22.
[0051] In this embodiment, a first ear piece 5 is further provided on the material retaining hopper 4. The material retaining hopper 4 is fixedly connected to the first bracket 21 or the second bracket 22 through the first ear piece 5, and the first ear piece 5 and the first bracket 21 or the second bracket 22 are detachably connected through a fixing bolt. During use, by loosening the fixing bolt, the material retaining hopper 4 can rotate between the first bracket 21 and the second bracket 22, thereby adjusting the angle between the material retaining hopper 4 and the first bracket 21 or the second bracket 22, so that the material retaining hopper 4 can fit more closely to the discharge port of the ore discharging machine.
[0052] In this embodiment, a second ear piece 6 is provided on the fixed seat 1. The fixed end of the electric push rod 3 is fixedly connected to the fixed seat 1 through the second ear piece 6, and the second ear piece 6 and the fixed end of the electric push rod 3 are detachably connected through a fixing bolt. Through the detachably arranged fixing bolt, the inclination angle of the electric push rod 3 can be adjusted according to requirements, thereby changing the rotatable stroke value of the electric push rod 3 for driving the push rod bracket 2.
[0053] In this embodiment, a telescopic rod 7 is further included. The telescopic rod 7 is arranged on the fixed seat 1. During use, the fixed seat 1 is arranged on an external object through the telescopic rod 7, which is convenient for users. At the same time, the height of the fixed seat 1 can be adjusted through the telescopic rod 7, so that the material retaining hopper 4 can fit more closely to the discharge port of the ore discharging machine when the electric push rod 3 drives the push rod bracket 2 to rotate.
[0054] In this embodiment, the telescopic rod 7 includes a first sliding rod 71, a second sliding rod 72, and a bolt 73. One end of the first sliding rod 71 is fixedly connected to the fixed seat 1, and the other end of the first sliding rod 71 is slidably disposed within the second sliding rod 72. Multiple groups of card slots are provided on the side wall of the first sliding rod 71, and card holes adapted to the card slots are provided on the side wall of the second sliding rod 72.
