[0002] Mining machinery refers to machinery directly used for mineral extraction and beneficiation operations. It includes mining machinery and mineral processing machinery. The working principle and structure of prospecting machinery are mostly the same or similar to those of mining machinery used to extract the same type of mineral. In a broad sense, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators and drainage machinery are also used in mining operations.
[0003] Forklifts are used in transporting ores of different sizes. To maintain the balance of the forklift, a counterweight needs to be installed at the rear of the forklift so that it does not tip forward when stacking goods. However, few existing forklifts have a device to adjust the counterweight, which fails to meet the needs of workers.
[0004] In view of this, this utility model is hereby proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a counterweight shell for mining machinery. This solves the problem that in order to maintain the balance of the forklift, a counterweight needs to be set at the rear of the forklift so that the forklift will not tilt forward when stacking goods. Existing forklifts rarely have a device for adjusting the counterweight.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A counterweight housing for mining machinery includes: a counterweight device body, an adjustment device installed inside the counterweight device body, a fixing block installed on the top of the counterweight device body, and a transmission device installed inside the fixing block;
[0008] The adjusting device includes four sliding rods. The main body of the counterweight device has an adapter groove inside, and the sliding rods are installed inside the adapter groove. One end of the sliding rod is equipped with an arc-shaped rod, and the other end of the arc-shaped rod extends to the bottom of the inner wall of the adapter groove. The surfaces of the sliding rod and the arc-shaped rod are slidably fitted with counterweight blocks. The adapter groove is equipped with four springs, which are sleeved on the surface of the sliding rods. One side of the counterweight block is equipped with a pull rope, and one end of the pull rope extends into the interior of the fixed block and cooperates with the transmission device.
[0009] Optionally, the transmission device includes a transmission component and a limiting component. The transmission component includes a drive motor, which is installed inside the fixed block. The output end of the drive motor is equipped with a transmission rod, one end of which is slidably engaged with a limiting block. The limiting component is installed inside the limiting block. One side of the fixed block is fitted with a rotating rod one, and the other side of the fixed block is fitted with a rotating rod two. Both rotating rod one and rotating rod two have sliding grooves inside them, and the limiting block is slidably engaged inside the sliding grooves.
[0010] Optionally, the fixed block is equipped with an electric push rod inside, and the output end of the electric push rod is equipped with a pull rod. The pull rod is rotatably engaged with the limit block, and the limit block is located at the connection between the rotating rod one and the rotating rod two.
[0011] Optionally, the limiting component includes a limiting plate, and the limiting block has a moving groove inside. The limiting plate is slidably fitted inside the moving groove, and one end of the transmission rod extending into the moving groove is fixedly connected to the limiting plate.
[0012] Optionally, the interior of the rotating rod 2 is provided with a T-shaped groove, and a T-shaped block is slidably fitted inside the T-shaped groove. The T-shaped block is fixedly connected to the rotating rod 1.
[0013] Optionally, five limiting discs are installed on the surfaces of rotating rod one and rotating rod two, with two limiting discs installed on the surface of rotating rod one and the other three limiting discs installed on the surface of rotating rod two, and the pull rope is wound between the two limiting discs.
[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0015] The operator starts the drive motor, causing the transmission rod to rotate the limit block. By activating the electric push rod, the operator moves the limit block to the connection point of rotating rod one and rotating rod two, allowing the limit block to rotate rotating rod one and rotating rod two. Under the action of the spring, the counterweight slides on the surface of the arc-shaped rod, thereby adjusting the center of gravity of the forklift. When the ore is too heavy, the forklift will not tilt forward when stacking goods, thus meeting the operator's needs for the forklift.

Detailed Implementation
[0027] The present invention will now be described in further detail with reference to the accompanying drawings.
[0028] Please see Figure 1-6 As shown, this embodiment provides a counterweight housing for mining machinery, including a counterweight device body 1, an adjustment device installed inside the counterweight device body 1, a fixing block 2 installed on the top of the counterweight device body 1, and a transmission device installed inside the fixing block 2.
[0029] The adjusting device includes four sliding rods 7. An adapter groove 3 is provided inside the main body 1 of the counterweight device. The sliding rods 7 are installed inside the adapter groove 3. One end of each sliding rod 7 is equipped with an arc-shaped rod 4, and the other end of the arc-shaped rod 4 extends to the bottom of the inner wall of the adapter groove 3. A counterweight block 5 is slidably fitted onto the surfaces of the sliding rods 7 and the arc-shaped rod 4. Four springs 8 are installed inside the adapter groove 3, and the springs 8 are sleeved on the surface of the sliding rods 7. A pull rope 6 is installed on one side of the counterweight block 5, and one end of the pull rope 6 extends into the interior of the fixed block 2 and engages with the transmission device. The main body of the counterweight device is located inside the forklift.
[0030] One application of this embodiment is as follows: When the ore is too heavy, the worker activates the electric push rod 13. The output end of the electric push rod 13 moves, driving the pull rod 16. Under the action of the limiting plate 21, the pull rod 16 moves, driving the limiting block 15 to move. When the limiting block 15 moves into the interior of the rotating rod 11, the worker activates the drive motor 9. The output end of the drive motor 9 rotates, driving the transmission rod 10 to rotate. The rotation of the transmission rod 10 drives the limiting block 15 to rotate, and the rotation of the limiting block 15 drives the rotating rod 11 to rotate. The rotation of the rotating rod 11 allows the pull rope 6 wrapped around the surface of the rotating rod 11 to loosen. Under the action of the spring 8, the counterweight 5 slides on the surface of the arc-shaped rod 4. When the counterweight 5 moves to the bottom of the inner wall of the adapter groove 3... This allows for the adjustment of the forklift's center of gravity. When additional counterweight is needed, the operator activates the electric push rod 13. The output end of the electric push rod 13 moves, driving the pull rod 16. Under the action of the limit plate 21, the pull rod 16 moves, driving the limit block 15 to move. When the limit block 15 moves into the interior of the rotating rod 2 17, the operator activates the drive motor 9. The transmission method is the same as described above, causing the limit block 15 to rotate, driving the rotating rod 2 17 to rotate. This allows the two counterweight blocks 5 on one side of the rotating rod 2 17 to move to the bottom of the inner wall of the adapter groove 3, thus increasing the counterweight of the forklift. Under the action of the T-slot 18 and the T-block 19, the rotating rod 1 11 and the rotating rod 2 17 can rotate, facilitating precise adjustment of the counterweight by the operator.
[0031] The transmission device in this embodiment includes a transmission component and a limiting component. The transmission component includes a drive motor 9, which is installed inside the fixed block 2. A transmission rod 10 is installed at the output end of the drive motor 9. One end of the transmission rod 10 is slidably engaged with a limiting block 15. The limiting component is installed inside the limiting block 15. A rotating rod 11 is engaged on one side of the fixed block 2, and a rotating rod 2 17 is engaged on the other side of the fixed block 2. Both the rotating rod 11 and the rotating rod 2 17 have sliding grooves 14 inside them. The limiting block 15 is slidably engaged inside the sliding grooves 14. The operator starts the drive motor 9. The output end of the drive motor 9 rotates, which drives the transmission rod 10 to rotate. The rotation of the transmission rod 10 drives the limit block 15 to rotate. The rotation of the limit block 15 drives the rotating rod 11 to rotate. The rotation of the rotating rod 11 can loosen the pull rope 6 wrapped around the surface of the rotating rod 11. Under the action of the spring 8, the counterweight 5 slides on the surface of the arc rod 4. When the counterweight 5 moves to the bottom of the inner wall of the adapter groove 3, the adjustment of the forklift's center of gravity can be completed.
[0032] In this embodiment, the fixed block 2 is equipped with an electric push rod 13. The output end of the electric push rod 13 is equipped with a pull rod 16, which rotatably engages with a limiting block 15. The limiting block 15 is located at the connection between rotating rod 11 and rotating rod 17. The limiting assembly includes a limiting plate 21. A moving groove 20 is formed inside the limiting block 15, and the limiting plate 21 is slidably engaged within the moving groove 20. One end of the transmission rod 10 extending into the moving groove 20 is fixedly connected to the limiting plate 21. When the operator starts the electric push rod 13, the output end of the electric push rod 13 moves, driving the pull rod 16. Under the action of the limiting plate 21, the pull rod 16 moves, causing the limiting block 15 to move.
