[0028] 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.

[0029] like Figures 1 to 3 As shown, the dust reduction system of the car tipper 20 according to the embodiment of the present invention comprises: a water supply component 5, a dust cover 1, a plurality of dust monitoring components 6, a support baffle 7 and a first spray component 8, the output end of the water supply component 5 is arranged on the dust cover 1, and the output end of the water supply component 5 sprays liquid into the dust cover 1, a plurality of dust monitoring components 6 are arranged in the dust cover 1 along the extension direction of the dust cover 1, the bottom of the dust cover 1 has an opening, the support baffle 7 is arranged on both sides of the opening of the dust cover 1, and the support baffle 7 is fixed with a first spray component, the first spray component is connected to the water supply component 5, and the output end of the first spray component opens toward the dust cover 1. The dust reduction system of the car tipper 20 according to the embodiment of the present invention can improve the dust reduction effect.

[0030] Specifically, the output end of the water supply component 5 is arranged on the dust cover 1, and the output end of the water supply component 5 faces downward to spray water mist inside the dust cover 1 to reduce dust. The dust cover 1 is semicircular, and a tipper 20 is arranged inside the dust cover 1 to turn over the materials in the train to unload the materials. When the tipper 20 unloads the materials, the dust generated spreads to the outside. At this time, the water supply component 5 starts to spray liquid into the protective cover to reduce dust.

[0031] At the same time, the first spray component 8 is arranged on the supporting baffles 7 on both sides of the lower end of the protective cover. Since most of the dust is concentrated on both sides of the protective cover opening, when unloading, the first spray component 8 sprays liquid on both sides of the protective cover opening to reduce the dust where the dust is concentrated on both sides of the opening.

[0032] At the same time, multiple dust monitoring components 6 are arranged on the dust cover 1 to monitor the dust monitoring components 6, so as to monitor the dust inside the dust cover 1 after the material is unloaded. At the same time, the amount of liquid output by the first injection component 8 and the water supply component 5 can be determined according to the dust concentration to cope with different dust concentrations, improve the dust reduction effect and avoid material waste.

[0033] In the dust reduction system of the dumper 20 of the embodiment of the present invention, the output end of the water supply assembly 5 is arranged on the dust cover 1 and faces the inside of the dust cover 1, and is used to spray water mist to reduce dust. By spraying water mist, the dust generated when the dumper 20 is unloading can be effectively humidified, thereby reducing its flying ability and achieving the effect of dust reduction.

[0034] At the same time, since dust tends to concentrate and spread outward at the opening of the dust cover 1, the first spray component 8 focuses on spraying liquid on these areas to further reduce the dust concentration. Through the coordinated work of the water supply component 5, the dust cover 1, the first spray component 8 and the dust monitoring component 6, effective control of the dust generated during the unloading process of the train tipper 20 is achieved. The water supply component 5 and the first spray component 8 reduce the dust concentration by spraying water mist, the dust cover 1 acts as a physical barrier to limit the spread of dust, and the dust monitoring component 6 provides real-time dust concentration data support, enabling the system to make intelligent adjustments according to changes in dust concentration, thereby improving dust reduction efficiency and saving resources.

[0035] In some embodiments, the dust reduction system of the tipping machine 20 also includes a guide component arranged on the supporting baffle 7, the guide component includes a guide plate 9 and a first telescopic component, one end of the first telescopic component is connected to the supporting baffle 7, and the other end of the first telescopic component is pivotally connected to the guide plate 9, and the bottom of the guide plate 9 is pivotally connected to the supporting baffle 7.

[0036] Specifically, there are two guide components on the support baffle 7, which correspond one to one with the support baffles 7 arranged on both sides of the opening of the dust cover 1. The dust on both sides of the opening of the dust cover 1 is guided so that the first injection assembly can perform dust reduction treatment on the guided dust again. The guide plate 9 is semicircular in shape. After the first telescopic component is extended and retracted, the guide plate 9 bends downward, so that after the dust hits the guide plate 9, under the limitation of the guide plate 9 and the support baffle 7, the dust flows between the ground and the support baffle 7, and then hits the first injection component 8.

[0037] The collision rate between the liquid sprayed by the first spraying component 8 and the dust is increased, that is, the probability of the dust and the sprayed water mist forming a nucleus is increased, thereby improving the dust reduction effect.

[0038] In the dust reduction system of the tipping machine 20 of the embodiment of the present invention, the guide plate 9 adopts a semicircular design. This shape helps to disperse the dust more evenly when it impacts and guides the dust to flow downward. When the first telescopic component is extended, the guide plate 9 rotates downward to form a space that is more conducive to dust gathering and guiding. After the dust impacts the guide plate 9, it is forced to flow to the space between the ground and the support baffle 7 under the joint limiting action of the guide plate 9 and the support baffle 7. At this time, the first spray component 8 arranged in this space sprays liquid, and then the collision rate between the liquid and the dust, that is, the probability of dust and the sprayed water mist forming nucleation, thereby improving the dust reduction effect.

[0039] In some embodiments, the guide component also includes a limit member arranged on the guide plate 9, the limit member is arranged inside the guide plate 9, and the first telescopic component is telescoped to rotate the guide plate 9 so that the bottom of the limit member inside the guide plate 9 contacts the support baffle 7 to limit the guide plate.

[0040] Specifically, the limiter is connected to the inner wall surface of the guide plate 9, and the limiter is arranged between the guide plate 9 and the supporting baffle 7. The contact between the limiter and the supporting baffle 7 ensures that the guide plate 9 can remain stable after rotating to a predetermined position and will not easily change its position due to the impact of external dust. At the same time, the output end of the water supply assembly 5 above the dust cover 1 sprays liquid downward to impact the guide plate 9, giving the guide plate 9 a downward pressure to prevent the guide plate 9 from flipping upward. At the same time, the limiter can support and limit the angle of the guide plate 9 after rotation, thereby improving the stability and safety of operation.

[0041] In some embodiments, the water supply assembly 5 includes a water storage member 52, a water supply member 53 and a second spray member 51. The second spray member 51 is arranged on the dust cover 1. The water storage member 52 is connected to one end of the water supply member 53, and the other end of the water supply member 53 is connected to the input end of the second spray member 51. The water supply member 53 can be an existing booster water pump. The second spray member 51 is arranged on the dust cover 1 to spray the pressurized water mist, collide with the dust particles and settle them. The number of second spray members 51 can be multiple, and multiple second spray members 51 are arranged in a matrix on the dust cover 1 to improve the dust reduction effect.

[0042] In some embodiments, the first spray component 8 and the second spray component 51 both include a spray gun 81 and a flow regulator 82 , one end of the flow regulator 82 is connected to the water supply component 53 , and the other end of the flow regulator 82 is connected to the spray gun 81 .

[0043] The flow regulating member 82 is suitable for adjusting the flow rate of the spray gun 81 so as to use different flow rates for different dust concentrations, thereby reducing the use cost and improving the dust reduction effect, so as to avoid the situation where when the dust concentration is too high, the liquid flow rate sprayed by the first injection component 8 and the second injection component 51 is small, resulting in a decrease in the dust reduction effect, or when the dust concentration decreases, the liquid flow rate sprayed by the first injection component 8 and the second injection component 51 is large, resulting in an increase in cost.

[0044] In the dust reduction system of the car tipper 20 of the embodiment of the present invention, the flow regulating member 82 is suitable for adjusting the flow rate of the spray gun 81 so as to use different flow rates for different dust concentrations, thereby reducing the use cost and improving the dust reduction effect.

[0045] In some embodiments, the dust reduction system of the dumper 20 further includes a temperature monitoring component and a controller, wherein the monitoring end of the temperature monitoring component faces the opening of the dust cover 1, and the input end of the controller is respectively connected to the water supply component 53 and the flow regulating component 82.

[0046] Specifically, temperature has a certain influence on the nucleation of dust and water mist. For example, within a certain temperature range, the nucleation effect of dust and water mist is better, but exceeding or falling below a certain temperature range will cause the nucleation of dust and water mist, affecting the dust reduction effect.

[0047] The controller is set to receive temperature and dust data, and then the controller adjusts the flow rate of the flow regulating member 82 of the first injection component 8 and the second injection component 51. That is, the flow rate of the flow regulating member 82 of the first injection component 8 and the second injection component 51 is determined by temperature and dust concentration.

[0048] The dust reduction system of the tipping machine 20 of the embodiment of the present invention can flexibly adjust the flow rates of the first injection component 8 and the second injection component 51 according to the dust concentration at different temperatures by setting a controller to receive temperature and dust data and then adjust the flow rates of the flow regulating parts 82 of the first injection component 8 and the second injection component 51, thereby ensuring the dust reduction effect and avoiding excessive waste and reducing costs.

[0049] In some embodiments, an entrance and exit 12 for entering and exiting the train compartment is provided in the extension direction of the dust cover 1, and a sliding groove 11 is provided on the top of the entrance and exit 12, a sliding rod is installed in the side wall of the sliding groove 11, and a guide slider 3 is slidably connected to the outer surface of the sliding rod, and a closed door 4 is fixedly installed under the guide slider 3.

[0050] By providing a dust cover 1 and a closed door 4 to form an enclosed space, the room of the tipping machine 20 is completely sealed to prevent the dust generated by the tipping machine 20 from diffusing to the outside when unloading. The generated dust is all gathered in the dust cover 1, which is convenient for dust reduction and treatment, thereby improving the dust reduction effect.

[0051] In some embodiments, observation ports 13 are provided on both sides of the dust cover 1 in the width direction.

[0052] In some embodiments, the dust suppression system of the dumper 20 further includes a hydraulic telescopic rod 10, one end of which is connected to the dust cover 1, and the other end of which is connected to the sealed door 4. The hydraulic telescopic rod 10 is suitable for pushing the sealed door 4 to move left and right to open or close the inlet and outlet 12 of the dust cover 1 in the front and rear directions.

[0053] In some embodiments, the dust reduction system of the dumper 20 further includes a cooling air supply assembly, one end of which is connected to the dust cover 1, and the output end of the cooling air supply assembly faces the opening of the dust cover 1. The cooling air supply assembly is suitable for supplying gas into the dust cover 1. For example, the cooling air supply assembly can be an air conditioner to output air with a lower temperature into the dust cover 1 to reduce the temperature in the dust cover 1, avoid the dust reduction effect caused by the dust cover 1 being too low or too high, and improve the stability of the equipment operation.
