Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Combined with reference Figure 1-Figure 4 The utility model provides a waste rock conveying device, including a conveyor 1 for conveying waste rocks. In the present application, the conveyor 1 can adopt a conveyor 1 with a baffle, which can improve the portability of waste rock transmission. A collecting bucket 2 is arranged above the conveyor 1. The collecting bucket 2 can cooperate with an external feeding device, such as an excavator, to concentrate the feeding of waste rocks at a certain point of the conveyor 1, which can effectively avoid the problem of waste rocks falling after feeding. A pair of rollers 3 are arranged in the collecting bucket 2, and one end of each roller 3 is rotatably connected to the inner wall of the collecting bucket 2 through a rotating shaft, and the roller 3 The other end is rotatably connected to the inner wall of the collecting bucket 2 through a hollow shaft 5. The collecting bucket 2 is provided with a crushing drive unit 4 for driving a pair of rollers 3 to rotate. A crushing block 31 is fixedly connected to the outer surface of the roller 3. The crushing block 31 can be used to crush the waste rock to change the size of the waste rock. A cooling chamber 32 is provided in the roller 3. The hollow shaft 5 is connected to the cooling chamber 32. A spray port 33 connected to the cooling chamber 32 is provided on the outer surface of the roller 3. A cooling water supply structure 6 is provided on the pair of hollow shafts 5. The cooling water supply structure 6 can be externally connected to a pump body for cooling water transportation.

[0025] The crushing drive unit 4 includes a crushing motor 41 fixedly connected to the outer surface of the collecting bucket 2, a gear 1 42 fixedly connected to the output end of the crushing motor 41, and a gear 2 43 fixedly connected to the rotating shaft end of each drum 3. A pair of gears 2 43 are meshed and connected to each other, and one of the gears 2 43 is meshed and connected to the gear 1 42.

[0026] Specifically, by starting the crushing motor 41, the gear 1 42 and the pair of gear 2 43 are driven to mesh and connect in turn, so that the pair of rollers 3 can rotate relatively, and the crushing blocks 31 on the rollers 3 can crush the waste rocks entering the collecting bucket 2.

[0027] A protective plate 10 is fixedly connected to the outer surface of the collecting bucket 2. The protective plate 10 is located above the crushing motor 41. The setting of the protective plate 10 can provide physical protection for the crushing motor 41 to avoid collision damage to the crushing motor 41 when waste rock is loaded.

[0028] It is worth noting that in the present application, shielding protection structures can also be provided at the positions of gear 1 42 and gear 2 43, so as to ensure the reliability of the external drive.

[0029] A reinforcing rib 11 is fixedly connected in the cooling cavity 32 . The reinforcing rib 11 can effectively improve the structural strength of the drum 3 by being supported in the cooling cavity 32 .

[0030] A filter screen is provided in the spray port 33 , which is not shown in the figure. The filter screen can provide filtering protection for the spray port 33 to prevent the spray port 33 from being blocked by waste rock fragments.

[0031] The cooling water supply structure 6 includes a rotary joint 61 arranged at the end of each hollow shaft 5 and a three-way conduit 62 arranged on a pair of rotary joints 61. The three-way conduit 62 can be sealed and rotatably connected to the hollow shaft 5 through the rotary joint 61, so as to meet the effect of rotary sealed transmission of cooling water.

[0032] Specifically, one end of the three-way conduit 62 can be connected to the pump body, and the cooling water transported by the pump body can be tap water. During the rotation of the drum 3, the tap water is collected in the cooling chamber 32, so that it can be sprayed through the spray port 33. In the process of crushing the waste rock by the crushing block 31, the dust phenomenon can be effectively suppressed. At the same time, the tap water in the cooling chamber 32 can provide a water cooling effect for the drum 3 and the crushing block 31, so as to avoid the problem of reducing the durability of the drum 3 and the crushing block 31 due to the high temperature of crushing.

[0033] A pair of buffer structures 7 are arranged on both sides of the conveyor 1, and the buffer structure 7 includes a buffer plate 71, and a support rod 8 is arranged on the buffer plate 71. One end of the support rod 8 is fixedly connected to a limiting seat 9, and the limiting seat 9 is detachably connected to the buffer plate 71. The other end of the support rod 8 is fixedly connected to the collecting bucket 2.

[0034] The buffer structure 7 also includes a slide rail 72, a spring shock absorber 73 and a base 74. The slide rail 72 and the base 74 are fixedly connected to the side position of the conveyor 1. The spring shock absorber 73 is fixedly connected to the base 74 and the buffer plate 71. The buffer plate 71 is slidably connected to the slide rail 72. The limit seat 9 is connected to the buffer plate 71 by bolts. The limit seat 9 is detachably connected to the buffer plate 71, so that the collecting bucket 2 and the structure thereon can be conveniently disassembled during overall transfer.

[0035] Specifically, in the process of the collecting bucket 2 receiving waste rocks, the gravity of the waste rocks can be transmitted to the spring shock absorber 73 through the buffer plate 71. At this time, the buffer plate 71 can slide adaptively on the slide rail 72, and the spring shock absorber 73 can buffer and reduce the energy, thereby providing impact-resistant protection for the collecting bucket 2. If the collecting bucket 2 is directly fixedly connected, the gravity of the waste rocks acting on the collecting bucket 2 can easily cause breakage of the connection and impact damage.
