[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figure 1-5An auxiliary tipping device for an ore transfer car includes a transfer car body 1, a transfer compartment 2 rotatably connected to the top of the transfer car body 1, and a tipping assembly 3 provided at the bottom of the transfer compartment 2. The tipping assembly 3 includes an inclined block 301, an inclined groove 302, a limiting slide groove 303, a threaded rod 304, a limiting slider 305, a limiting block 306, and a stepper motor 307. The inclined block 301 is fixedly connected to the bottom of the transfer car body 1, the inclined groove 302 is opened at the bottom of the inclined block 301, the limiting slide groove 303 is opened at the top of the transfer car body 1, the threaded rod 304 is rotatably connected to the inside of the limiting slide groove 303, the limiting slider 305 is slidably connected to the inside of the limiting slide groove 303 and is adapted to the limiting slide groove 303, the limiting block 306 is fixedly connected to the top of the limiting slider 305, and the stepper motor 307 is fixedly installed at the rear end of the transfer car body 1.

[0025] The bottom of the inclined block 301 is inclined, and the top of the limiting slider 305 is also inclined. The limiting block 306 is located inside the inclined groove 302 and can play a limiting role. The setting of the tipping component 3 is that by starting the stepper motor 307, the drive shaft of the stepper motor 307 drives the threaded rod 304 to rotate. During the rotation of the threaded rod 304, the limiting slider 305 is adapted to the limiting groove 303 and threadedly connected to the threaded rod 304, so it can drive the limiting slider 305 to move. During the movement of the limiting slider 305, the top inclined surface of the limiting slider 305 contacts the bottom inclined surface of the inclined block 301, which can drive the transfer car 2 to tip over. This utility model uses a threaded rod 304 to drive the limiting slider 305 to move inside the limiting groove 303, so that the inclined surface at the top of the limiting slider 305 contacts the inclined surface at the bottom of the inclined block 301, thereby tilting the transfer carriage 2, which facilitates the unloading operation for the staff and effectively improves practicality and convenience.

[0026] Furthermore, the sides of the transfer carriage 2 and the transfer car body 1 are provided with a limiting component 4. The limiting component 4 includes a limiting post 401, an auxiliary card plate 402 and a limiting groove 403. The limiting post 401 is fixedly connected to the left and right sides of the transfer carriage 2.

[0027] The auxiliary card plate 402 is fixedly connected to the left and right sides of the transfer vehicle body 1. The limiting groove 403 is opened inside the auxiliary card plate 402 and the limiting groove 403 is arc-shaped. The limiting post 401 is located inside the limiting groove 403.

[0028] With the setting of the limiting component 4, during the tipping of the transfer carriage 2, the limiting post 401 moves in an arc shape inside the limiting groove 403. When the transfer carriage 2 tipps to its maximum extent, the limiting post 401 also moves synchronously to the deepest part of the limiting groove 403 and contacts the inner wall of the limiting groove 403. Thus, the limiting groove 403 can limit the limiting post 401, further limiting the tipping angle of the transfer carriage 2. This utility model, by limiting the limiting post 401 through the limiting groove 403, improves the limitation of the tipping angle of the transfer carriage 2, greatly improving the safety and stability of the unloading operation for workers.

[0029] Furthermore, the front end of the transfer carriage 2 is provided with a discharge port 5, and a baffle 6 is rotatably connected inside the discharge port 5. Hydraulic rods 7 are rotatably connected to the left and right sides of the transfer carriage 2, and the telescopic ends of the hydraulic rods 7 are rotatably connected to the sides of the baffle 6.

[0030] The opening of the discharge port 5 facilitates the unloading operation of the staff. The installation of the baffle 6 can block the discharge port 5 to prevent the ore from falling. The installation of the hydraulic rod 7 allows the baffle 6 to be opened by extending the telescopic end of the hydraulic rod 7, and to be closed by retracting the telescopic end of the hydraulic rod 7.

[0031] Furthermore, the bottom of the transfer carriage 2 is symmetrically distributed and fixedly connected with buffer pads 8, the bottom of the transfer carriage 1 is rotatably installed with rotating rollers 9, and the rear end of the transfer carriage 1 is fixedly installed with a control panel 10.

[0032] The installation of the buffer pad 8 can buffer and reduce shock between the transfer carriage 2 and the transfer car body 1 during the repositioning process of the transfer carriage 2.

[0033] Furthermore, the drive end of the stepper motor 307 is connected to the threaded rod 304, the limit block 306 is adapted to the inclined groove 302, and the limit slider 305 is threadedly connected to the threaded rod 304.

[0034] In summary:

[0035] When in use, first rotate the roller 9 to move the transfer vehicle 1 to a suitable position; then start the hydraulic rod 7 to extend the telescopic end of the hydraulic rod 7. During the extension process, the baffle 6 can be opened, and some ore will be discharged through the discharge port 5.

[0036] Then, the stepper motor 307 is started, which causes the drive shaft of the stepper motor 307 to drive the threaded rod 304 to rotate. During the rotation of the threaded rod 304, the limiting slider 305 is adapted to the limiting slide groove 303 and threadedly connected to the threaded rod 304, which can drive the limiting slider 305 to move. During the movement, the top inclined surface of the limiting slider 305 contacts the bottom inclined surface of the inclined block 301, which can drive the transfer car 2 to tip over, so that all the ore inside the transfer car 2 is discharged from the discharge port 5.

[0037] During the process of the transfer carriage 2 being overturned, the limiting groove 403 can limit the limiting post 401, further limiting the overturning angle of the transfer carriage 2.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
