DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the implementation of the present invention, for the sake of convenience, the cross-sectional diagram showing the device structure will not be partially enlarged according to the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Figure 1-Figure 3The schematic diagram of the whole structure of the stone waste crushing equipment of the utility model is shown. Figure 1-Figure 3 The present embodiment is a stone waste crushing device, comprising a crushing box 100, wherein both sides of the crushing box 100 are provided with crushing rollers 110 driven to rotate by a driving device, a dust reduction and feeding cabin 200 is horizontally fixed at the bottom of the crushing box 100, and a feeding port 220 connected to the discharge end of the crushing box 100 is provided at one end of the top of the dust reduction and feeding cabin 200, a spiral conveying rod 210 is provided at the bottom of the inner side of the dust reduction and feeding cabin 200 along its length direction, and a spiral conveying rod 210 is provided at the outer side of the dust reduction and feeding cabin 200 to drive the spiral conveying rod 210. A servo motor 240 rotates the conveying rod 210, and the dust reduction conveying cabin 200 is provided with a discharge port 230 at the lower part of the opposite end of the feed port 220. A spray pipe 300 is provided on the inner top of the dust reduction conveying cabin 200 along its length direction, and the spray pipe 300 is provided along the conveying direction of the spiral conveying rod 210. A dust collecting hood 400 is provided directly above the crushing box 100, and an exhaust assembly 410 is provided on the outside of the crushing box 100 for sucking the dust collecting hood 400 and guiding the dust into the feed port 220.

[0021] A feed hopper 120 is extended outwardly on one side of the upper end of the crushing box 100, and guide plates 130 are provided on the inner side of the crushing box 100 and are respectively located on both sides above and below the crushing roller 110. The guide plates 130 can smoothly guide the stones input by the feed hopper 120 into the rolling end of the crushing roller 110, and at the same time, the crushed stones can be introduced into the feed port 220 and the dust reduction feed cabin 200; in addition, the feed hopper 120 is extended laterally to avoid the position of the dust collecting hood 400. In this way, when the dust generated after crushing rises, it can be directly sucked by the dust collecting hood 400 directly above, which is simple and effective.

[0022] A plurality of atomizing nozzles 310 are arranged at the bottom of the spray pipe 300 along its length direction, and a water pump 320 is also arranged at the upper end of the dust reduction conveying cabin 200, whose water outlet end is connected to the spray pipe 300 and whose water inlet end is connected to the water source. When the dust reduction conveying cabin 200 conveys the crushed material through the spiral conveying rod 210, the crushed material will carry a large amount of deposited and floating dust. Therefore, the spray pipe 300 can use the atomizing nozzle 310 to mist and wet the stones and dust pushed and turned below, so as to achieve the purpose of efficient dust suppression and avoid the problem of excessive dust dispersion during unloading and loading.

[0023] The exhaust assembly 410 includes an air duct 4101 connected to the dust hood 400 at one end and to the feed port 220 at the other end, and a fan 4102 arranged on the air duct 4101. During operation, since the crushing roller 110 is located below the dust hood 400 and the dust generated during crushing will drift upward, the dust hood 400 can promptly suck the dust diffused upward under the action of the fan 4102 and the air duct 4101, and the extracted dust is directly introduced into the feed port 220 and the dust reduction transport cabin 200 through the air duct 4101 for subsequent humidification and dust reduction, thereby avoiding the pollution caused by the dust drifting outward through the feed hopper 120.

[0024] Furthermore, a protective steel mesh 420 is provided at the bottom entrance of the dust hood 400 , and the protective steel mesh 420 can prevent the broken and splashed stones below from entering the air duct 4101 through the dust hood 400 , thereby protecting the fan 4102 .

[0025] Furthermore, support legs 500 are fixed on both sides of the bottom of the dust reduction and conveying cabin 200. The entire device can be propped up and positioned by the provided support legs 500, making it more convenient to use.

[0026] In summary, in the present embodiment, a stone waste crushing device is used. When in operation, the uncrushed stone is introduced into the crushing box 100 through the feed hopper 120, and the incoming stone waste is crushed by the crushing roller 110. The crushed stone will directly enter the dust reduction feed cabin 200 through the feed inlet 220. When the dust reduction feed cabin 200 conveys the crushed material through the spiral conveying rod 210, the crushed material will carry a large amount of deposited and floating dust, so the spray The tube 300 can wet the stones and dust pushed and turned over from below through the atomizing nozzle 310, so as to achieve the purpose of efficient dust suppression. Moreover, the dust collecting hood 400 can timely suck the dust diffused upward under the action of the fan 4102 and the air duct 4101. The extracted dust is directly introduced into the feed port 220 and the dust reduction transport cabin 200 through the air duct 4101 for subsequent humidification and dust reduction, thereby avoiding the pollution caused by the dust drifting outward through the feed hopper 120.

[0027] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
