[0027] The embodiments of the present application are described in detail below, examples of which are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0028] As shown in Figure 1 and Figure 2 , the hopper-type mine car 100 of the embodiment of the present application comprises a frame 1, a hopper 2 and a turnover assembly 3, the hopper 2 is rotatably connected with the frame 1; the turnover assembly 3 comprises a worm wheel 31 and a worm 32 which are engaged with each other, the worm wheel 31 is connected with the hopper 2, and the worm 32 is rotatably connected with the frame 1.

[0029] The hopper-type mine car 100 of the embodiment of the present application, the operator drives the worm 32 to rotate, and the rotation of the worm 32 can control the turnover of the hopper 2 through the engagement of the worm 32 and the worm wheel 31. Since the engagement of the worm 32 and the worm wheel 31 has a self-locking function, the worm wheel 31 cannot drive the worm 32 to rotate reversely, which can prevent the hopper 2 from suddenly dumping due to excessive weight, thereby improving the operation safety of the operator.

[0030] In addition, the rotation speed of the worm 32 can be controlled to control the turnover speed of the hopper 2, and the transmission of the worm 32 and the worm wheel 31 also has a speed reduction function, which can reduce the turnover speed of the hopper 2 and improve the stability of the turnover of the hopper 2.

[0031] The lower side of the frame 1 is provided with two groups of track wheels, and the hopper-type mine car 100 can walk along the track under the traction of the winch to transport materials to the unloading site; the two sides of the frame 1 are also provided with connectors (not shown in the figure), and a plurality of hopper-type mine cars 100 can be connected with each other through the connectors, so that the winch can simultaneously pull a plurality of hopper-type mine cars 100.

[0032] As shown in Figure 1 andFigure 2 As shown, the two support shafts 21 are fixedly connected to the skip 2, the axes of the support shafts 21 are consistent with the running direction of the skip car 100, the two support shafts 21 are coaxially arranged and oppositely arranged along the rotation axis of the skip 2 on the two sides of the skip 2; the two bearing seats are boltedly connected to the frame 1, and the two support shafts 21 are respectively arranged in the two bearing seats, thereby realizing the stable connection between the skip 2 and the frame 1.

[0033] The turning assembly 3 is arranged on the side of the bearing seat away from the skip 2, the worm wheel 31 is sleeved on the support shaft 21, the worm 32 is engaged with the worm wheel 31, and the two ends of the worm 32 are rotatably supported on the frame 1 through the bearing seat; thus, the operator can drive the worm 32 to rotate to drive the skip 2 to turn over, so that the skip 2 has a loading state and an unloading state.

[0034] In the loading state, the opening of the skip 2 faces upward, and the material can fall into the skip 2; in the unloading state, the opening of the skip 2 is inclined downward, and the material in the skip 2 can be unloaded at the unloading site.

[0035] In some embodiments, the skip car 100 further comprises a first shell 33, the first shell 33 is connected with the frame 1, and the first shell 33 covers the turning assembly 3.

[0036] Because the coal mine environment is relatively complex, the first shell 33 is arranged to protect the worm 32 and the worm wheel 31, prevent impurities such as dust particles in the external environment from entering the meshing position of the worm 32 and the worm wheel 31, and cause the meshing of the worm 32 and the worm wheel 31 to jam, thereby prolonging the service life of the worm 32 and the worm wheel 31.

[0038] Through the above arrangement, the two sides of the skip 2 are connected with the frame 1, so that the rotation connection between the skip 2 and the frame 1 is more stable; at the same time, two operators can simultaneously drive the worms 32 of the two turning assemblies 3 to rotate on the two sides of the skip 2, exert a turning force on the two sides of the skip 2, so that the skip 2 is balanced in force, thereby further improving the unloading stability of the skip 2.

[0039] In some embodiments, the skip car 100 further comprises a transmission assembly 4, the worm 32 of the first turning assembly and the worm 32 of the second turning assembly are drivingly connected through the transmission assembly 4.

[0040] Through the above arrangement, the first and second turnover assemblies are in transmission connection, and an operator only needs to operate one of the turnover assemblies 3 to drive the two turnover assemblies 3 to act synchronously, so that the turnover operation of the dump body 2 can be realized without two operators, thereby improving the operation convenience of the dump truck 100.

[0041] In some embodiments, as shown in Figure 1 the transmission assembly 4 includes a transmission shaft 41 and two bevel gear sets 42, the transmission shaft 41 is rotatably connected with the vehicle frame 1, and the two bevel gear sets 42 are respectively arranged at two ends of the transmission shaft 41, and the two ends of the transmission shaft 41 are connected to the worm 32 of the first and second turnover assemblies through the two bevel gear sets 42.

[0043] In some embodiments, the transmission shaft 41 is arranged at the lower side of the dump body 2.

[0044] By arranging the transmission assembly 4 at the lower side of the dump body 2, sufficient turnover space can be left for the dump body 2, so that the dump body 2 can be turned to both sides of the track.

[0045] In some embodiments, as shown in Figure 2 the bevel gear set 42 includes a first bevel gear 421 and a second bevel gear 422 that are in mesh with each other, the first bevel gear 421 is connected with the transmission shaft 41, and the second bevel gear 422 is connected with the worm 32.

[0046] The operator applies a force to the transmission shaft 41, which can drive the two first bevel gears 421 at both ends of the transmission shaft 41 to rotate simultaneously, and then drive the second bevel gear 422, the worm 32 and the worm gear 31 to rotate in sequence, so that the first and second turnover assemblies act synchronously, thereby realizing the unloading turnover of the dump body 2.

[0047] As an example, as shown in Figure 2 the worm 32 extends vertically downward and penetrates through the first housing 33, the worm 32 is connected with the second bevel gear 422 through a shaft body 34, and the shaft body 34 is rotatably connected with the vehicle frame 1 through a support, which can improve the stability of the shaft body 34.

[0048] The transmission shaft 41 is parallel to the support shaft 21, and the transmission shaft 41 is rotatably connected with the support shaft 21 through a bearing seat, the two first bevel gears 421 are sleeved at both ends of the transmission shaft 41, and the two first bevel gears 421 can be driven to rotate synchronously through the transmission shaft 41.
