The steel wire brush roller 4 is used to roll and sweep the mineral particles deposited on the ground and the mine dust falling to the ground into the bucket body 3 during continuous rolling.

[0024] The rotating drive mechanism is provided with two, which are symmetrically arranged at the two ends of the steel wire brush roller 4; referring to Figure 3Each rotating drive mechanism comprises a hydraulic motor 10, a motor gear 12, a brush roller gear 13 and a chain 14; the hydraulic motor 10 is fixed on the upper hopper body wall with its output shaft parallel to the connecting shaft of the steel wire brush roller 4, the motor gear 12 is sleeved and fixed on the output shaft of the hydraulic motor 10 through its central hole, so as to drive the motor gear 12 to rotate by the hydraulic motor 10; the brush roller gear 13 is sleeved and fixed on the connecting shaft of the steel wire brush roller 4 through its central hole, and the chain 14 is an annular chain sleeved on the motor gear 12 and the brush roller gear 13, so that the chain 14 forms a chain transmission mechanism with the motor gear 12 and the brush roller gear 13, and then, under the rotation of the motor gear 12, the brush roller gear 13 drives the steel wire brush roller 4 to rotate synchronously. Figure 1 The rotating direction of the steel wire brush roller 4 is set as counterclockwise rotation, so as to sweep the ore powder and ore dust on the ground into the hopper body 3.

[0025] The oil inlet end and the oil outlet end of the hydraulic motor 10 on the two rotating drive mechanisms are respectively connected with hydraulic pipelines, the other ends of the two hydraulic pipelines connected with the oil inlet end and the other ends of the two hydraulic pipelines connected with the oil outlet end are respectively connected with two standby ports of a hydraulic control multi-way reversing valve in the hydraulic system of the loader; correspondingly, a rotating control button is additionally arranged in the cab of the vehicle body 1, so that the operating personnel can start the rotating drive mechanism in the cab, thereby driving the steel wire brush roller 4 to rotate.

[0028] In actual application, the wire brush roller 4 will wear out and the bristles will become shorter after a period of cleaning use. At this time, the front bucket body 2 needs to be lowered through fine-tuning to adjust the contact amount between the wire brush roller 4 and the bottom surface; the actual operation of this adjustment is to reduce the angle between the front bucket body 2 and the bucket body 3; in this embodiment, the first U-shaped fixing frame 701 and the second U-shaped fixing frame 702 are generally connected to the front bucket body 2 and the bucket body 3 respectively by welding. When the angle between the two bucket bodies needs to be adjusted, any U-shaped fixing frame is disassembled and shifted, and then 703 and the two fixing bolts are installed to achieve adjustment.

[0029] The spray mechanism includes a first spray pipe 5 arranged at the front end of the front bucket body 2 and two second spray pipes 6 symmetrically arranged on both sides of the front bucket body 2.

[0030] The first spray pipe 5 includes a U-shaped pipe body 502, and a plurality of nozzles 501 are arranged on the U-shaped pipe body along the length direction of the pipe body; specifically, the length of the U-shaped pipe body 502 is adapted to the transverse width of the front end of the front bucket body 2, so that the U-shaped pipe body 502 is arranged along the transverse width direction of the front bucket body 2, and the two ends are clamped and fixed on the two side walls of the front bucket body 2, and the U-shaped pipe body 502 is kept obliquely downward from front to back; the plurality of nozzles 501 are arranged from the U-shaped pipe body 502 to the front of the bucket body 2. The tube body 502 is evenly distributed from one end to the other and is vertically fixed on the bottom wall of the U-shaped tube body 502, so that the water pumped into the U-shaped tube body 502 is sprayed obliquely forward toward the ground from each nozzle 501; preferably, the nozzle 501 adopts an atomizing nozzle, and the nozzle 501 arranged on the U-shaped tube body 502 sprays atomized water at a spraying angle of 45° obliquely forward; on the U-shaped tube body 502, one end of the tube body is the water inlet end and the other end is the water outlet end.

[0031] The two second spray pipes 6 are symmetrically arranged on the two side walls of the front bucket body 2; specifically, the second spray pipe 6 includes an annular tube body, which is fixed on one side wall of the front bucket body 2 in an oblique upward manner from front to back; two nozzles are vertically fixed on the tube body near the front end of the front bucket body 2, so that it sprays in an oblique upward manner; preferably, the nozzle on the second spray pipe 6 also adopts an atomizing nozzle, and the nozzle arranged on the annular tube body sprays atomized water at a spray angle of 45° obliquely upward; the water inlet end and the water outlet end are respectively provided at adjacent positions on the annular tube body.

[0032] In actual application, a water pump start button is correspondingly provided in the cab of the loader's body 1, which is electrically connected to the water pump in the water tank 8, so that the operator can remotely turn on and off the water pump in the cab and control the first spray pipe 5 and the second spray pipe 6 to spray atomized water outward.

[0033] The spray mechanism is structurally designed to cooperate with the first spray pipe 5 and the two second spray pipes 6 to realize that when the sweeper is cleaning the mine dust generated during the ore transfer process in the yard, the dust is first suppressed by sprinkling water to make the mine dust fall to the ground, and then the rotating wire brush roller 4 is used to brush and collect it into the bucket body 3.

[0034] The water tank 8 is fixed at the rear end of the vehicle body, which not only meets the purpose of storing spray water in large capacity, but also can be used to set a cleaning device at the front end of the loader for counterweight; a water pump is provided in the water tank 8, and three water inlets and three water return ports are provided on the tank body; among them, the three water inlets are respectively connected to the water inlet ends of the first spray pipe 5 and the two second spray pipes 6 through water supply pipes, and the three water return ports are respectively connected to the water outlet ends of the first spray pipe 5 and the two second spray pipes 6 through water supply pipes, so as to pump high-pressure water to the first spray pipe 5 and the two second spray pipes 6 through the water tank 8, and then spray mist water outward through the nozzles on the spray pipes.

[0035] See also Figure 1 The specific implementation method of using the road sweeper for mineral storage yard to suppress dust and clean the mineral storage yard is described as follows:

[0036] S1. The operator controls the loader's boom 16 to lift the bucket 3, ensuring that it and the front bucket 2 are clear of the ground. The operator then drives the loader to the designated cleaning surface.

[0037] S2. The operator starts the water pump so that when the operator drives the loader forward on the designated road surface to be cleaned, the nozzles of the first spray pipe 5 and the second spray pipe 6 spray atomized water forward, so that the mineral dust in the air on the road surface to be cleaned falls to the ground during the spraying of the atomized water;

[0038] S3. When the operator drives the loader to the end of the road to be cleaned, the water pump is kept in the started state; at the same time, the operator controls the loader arm 16 to be lowered until the bottom surface of the bucket body 3 is parallel to the ground and lightly touches the ground, or leaves a small gap with the ground; at this time, the bristles of the wire brush roller 4 should remain in contact with the ground to effectively brush the mineral powder on the road surface;

[0039] S4. The operator starts the hydraulic motor of the rotation drive mechanism to rotate the wire brush roller 4 counterclockwise. At the same time, the operator drives the loader backward along the road surface to be cleaned. During the reversing process of the loader, the wire brush roller 4 rotates to sweep the mineral powder on the road surface into the bucket 3 for aggregate collection. Since the first spray pipe 5 and the second spray pipe 6 still keep spraying atomized water during the above cleaning process, the brushing process of the wire brush roller will not cause the problem of secondary dust emission of mineral powder.

[0040] S5. When the loader retreats to the initial position of the road to be cleaned, the operator turns off the water pump and the hydraulic motor, and then controls the loader arm 16 to lift the bucket body to a tilted downward position to prevent the mineral powder collected in the bucket body 3 from being scattered; then, the operator drives the loader to the mineral powder collection location, and controls the loader arm to drive the bucket body 3 to tilt downward to dump the collected mineral powder into the designated location.
