DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] A drum belt conveyor according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, an embodiment of the present invention proposes a drum-type belt conveyor, comprising: a belt conveyor body 1, a slag cleaning mechanism and a spraying device, wherein both ends of the belt conveyor body 1 are respectively connected to a support frame 2; the slag cleaning mechanism is arranged at the bottom of the lower belt of the belt conveyor body 1, and the slag cleaning mechanism comprises a plate brush 8, a first lifting device 9 and a receiving box 14, the upper opening of the receiving box 14 is used to receive the material dropped by the brush, the bottom of the first lifting device is fixedly connected to the receiving box 14, the plate brush 8 is detachably connected to the top of the first lifting device, the first lifting device is driven to make the plate brush 8 contact with the lower belt, and the spraying device Arranged on the receiving box 14, the spray device includes a water inlet pipe, a spray ring pipe 13, a spray riser 12, a pump body 10 and an atomizing nozzle 11. The spray ring pipe 13 is arranged in a horizontal direction, and the spray ring pipe 13 is fixedly connected to the upper edge of the receiving box 14. The water inlet pipe is connected to one side of the spray ring pipe 13, and the pump body 10 is connected to the water inlet pipe. A plurality of spray risers 12 are provided and are respectively connected to the top of the spray ring pipe 13. The spray riser 12 is arranged in a vertical direction, and the atomizing nozzle 11 is connected to the spray riser 12. The atomizing nozzle 11 sprays toward the inner side of the receiving box 14.

[0025] The embodiment of the present invention provides a slag cleaning mechanism so that the belt conveyor can clean the lower belt during operation without affecting the progress of the project. The first lifting device 9 can be provided to adjust the height of the brush 8 so that the brush 8 fits the lower belt to improve the cleaning effect. The spray device can be provided to reduce dust during the cleaning process. The receiving box 14 can be provided to collect the cleaned coal slag for recycling.

[0026] Furthermore, the water inlet pipe is connected to the solenoid valve. When there is a lot of dust during belt cleaning, the solenoid valve is controlled to start the spraying device.

[0027] Furthermore, the first lifting device 9 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is fixedly connected to the receiving box 14, the telescopic rod of the hydraulic cylinder is fixedly connected to the scrub brush 8, and the telescopic rod is telescopic in the vertical direction.

[0028] Furthermore, a base is installed at the bottom of the first lifting device 9, and the lower part of the base is installed in the foundation pit. The belt conveyor body 1 includes a head, a middle part and a tail part, and multiple bottom plates are installed at the bottom. Among them, four anchor rods are respectively driven on the bottom plates of the head and tail parts. A group of fixed anchor rods is driven at intervals of 0.5 meters on the bottom plate of the middle part, and 6 groups of anchor rods are driven on each bottom plate. All anchor rods are fastened to the bottom plate of the belt conveyor with fasteners to make the structure more stable.

[0029] Furthermore, the anchor rods are selected from left-handed fine-threaded and other strong threaded anchor rods.

[0030] Further, the scrubber brush 8 is connected to the top of the first lifting device 9 by bolts.

[0031] It should be noted that other conventional structures such as baffles are also provided on both sides of the drum belt conveyor, which are not shown in the figure.

[0032] In some embodiments, Figure 1 As shown, the bottom of the receiving box 14 is connected to a frame 15, the bottom of the frame 15 is provided with a wheel body, one side of the frame 15 is fixedly connected to a mounting plate, and the pump body 10 is connected to the mounting plate, so that the slag cleaning mechanism is easy to move.

[0033] Furthermore, the wheel body is provided with a matching parking device.

[0034] Furthermore, the frame 15 may be equipped with a driving device and a control box, and the operation of the frame 15 may be remotely controlled.

[0035] In some embodiments, Figure 1 As shown, the bottom of the support frame 2 is connected to the second lifting device 7. The lifting of the support frame 2 can be controlled according to the actual use environment.

[0036] Furthermore, the second lifting device 7 is a hydraulic device.

[0037] In some embodiments, Figure 1 As shown, the drum belt conveyor also includes a buffer frame, which is arranged on the unloading side of the belt conveyor body 1 to reduce dust during unloading. When the coal blocks are unloaded, they first fall on the buffer frame and then slide to the ground, which can play a role in dust reduction.

[0038] In some embodiments, Figure 3As shown, the buffer rack includes: a base 19, a support plate 3, a buffer 18 and a sleeve 6. The sleeve 6 is fixedly connected to the base 19. The sleeve 6 has an upper opening. The buffer 18 is arranged at the bottom of the sleeve 6. The lower end of the support plate 3 is fixedly connected to the pressure rod 4. The pressure rod 4 is inserted into the sleeve 6. The bottom of the pressure rod 4 is fixedly connected to the slider 16. The lower end of the slider 16 is connected to the buffer 18. The slider 16 and the pressure rod 4 slide in the sleeve 6 along the vertical direction under the elastic force of the buffer 18. When the coal block falls on the buffer rack, the support plate 3 will move downward to squeeze the buffer 18. When the coal block slides to the ground, the support plate 3 rises back to its original position due to the rebound force of the buffer 18.

[0039] In some embodiments, the buffer 18 is a spring, the lower end of the spring is fixedly connected to the base 19 , and the upper end of the spring is connected to the slider 16 .

[0040] In some embodiments, Figure 3 As shown, one side of the support plate 3 away from the belt conveyor body 1 is tilted downwards, so that the coal blocks falling on the support plate 3 can slide downwards.

[0041] In some embodiments, Figure 3 As shown, the drum belt conveyor also includes a limit card 17. A plurality of limit holes are provided on the side wall of the sleeve 6 in the vertical direction. The limit card 17 is inserted into the limit hole and abuts against the upper end surface of the slider 16 to limit the highest point of the slider 16.

[0042] In some embodiments, Figure 4 As shown, the limit card 17 has a U-shaped structure, and a notch is formed in the middle of the limit card 17 for inserting the pressure rod 4. After the notch of the limit card 17 is inserted into the pressure rod 4, under the elastic force of the buffer 18, the lower end surface of the limit card 17 fits with the upper end surface of the slider 16.

[0043] Furthermore, each set of limiting holes includes a horizontal long hole located on one side of the sleeve 6, and two short holes located on the other side of the sleeve 6, and the long hole and the short hole are flush in the horizontal direction. The limiting card 17 includes a push rod and two plug rods, the two plug rods are parallel to each other, and the two plug rods are fixedly connected to the two ends of the push rod to form a U-shaped structure. The function of the long hole is to insert the push rod, and the function of the two short holes is to insert the two plug rods to form a limiting structure. It should be noted that when inserting, the plug rod will first pass through the long hole until it is inserted into the short hole. When the plug rod is inserted and passes through the short hole, the notch formed just fits into the pressure rod 4. At this time, the push rod is located in the long hole, and the limiting card 17 and the side wall of the sleeve 6 form a limiting structure. Since the outer diameter of the slider 16 is larger than the outer diameter of the pressure rod 4, the slider 16 abuts against the lower end of the limiting card 17, thereby limiting the moving position of the support plate 3.

[0044] In some embodiments, Figure 3 , 4As shown, one side of the limit card 17 is connected to the handle 5 to facilitate pulling out the limit card 17 .
