DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-5 As shown, a splash-proof dust-reducing construction slag crusher comprises: a main body frame 1, a protective top cover 2 is arranged on the main body frame 1, two stone crushing bodies 3 are arranged between the main body frame 1 and the protective top cover 2, the output end of the stone crushing body 3 is driven by a driving motor 4, and the feed end of the protective top cover 2 is provided with a splash plate 6.

[0031] Specifically, the protective top cover 2 is provided with a suction fan 5, an output end of the suction fan 5 is provided with a suction pipe 51, the protective top cover 2 is provided with a dust removal port 21 corresponding to the suction pipe 51, and one end of the suction pipe 51 extends into the dust removal port 21.

[0032] Specifically, a material breaking cone wall 22 is provided on the inner wall of the protective top cover 2 , an assembly portion 23 is provided in front of the material breaking cone wall 22 , and the splash plate 6 is matched with the assembly portion 23 .

[0033] like Figure 3-4 As shown, the crushing body 3 includes a main shaft 31, one end of which is provided with a synchronous pulley 32, and the other end extends into the shaft seat 38. A plurality of discs 33 are slidably fitted on the main shaft 31, and a bushing 34 is provided between the discs 33. The bushing 34 is slidably fitted on the main shaft 31. A positioning hoop 35 is provided outside the end of the disc 33, and the positioning hoop 35 is fixedly fitted on the main shaft 31. A plurality of double-headed threaded rods 36 are slidably fitted on the disc 33, and a hammer 37 is slidably fitted on the double-headed threaded rod 36, and the hammer 37 is located between the discs 33.

[0034] Specifically, a first synchronous belt 39 is provided on the synchronous pulley 32 , and the two crushing bodies 3 are driven and matched through the first synchronous belt 39 . A second synchronous belt 42 is provided on the output end of the driving motor 4 , and the driving motor 4 is driven and matched with the synchronous pulley 32 through the second synchronous belt 42 .

[0035] Specifically, two ends of the double-threaded rod 36 are threadedly matched with nuts, and the double-threaded rod 36 is fixed on the disk body 33 with the nuts.

[0036] Specifically, the positioning hoop 35 can be fixed to the main shaft 31 by fastening bolts to facilitate subsequent disassembly and maintenance of the hammer body 37 .

[0037] Furthermore, the driving motor 4 is used as a power source to drive the two crushing bodies 3 to move synchronously through transmission, and the hammer body 37 rotates to crush the slag through hammering.

[0038] Furthermore, the crushing cone wall 22 can further enhance the crushing effect. The crushed stones splashed by the hammer body 37 when it strikes the slag will contact the crushing cone wall 22, thereby achieving the purpose of further crushing.

[0039] like Figure 6-8 As shown, guide holes 61 are provided at both ends of the splash plate 6, and threaded columns 62 are slidably fitted in the guide holes 61.

[0041] Furthermore, the splash plate 6 is used to seal the inlet port. When the slag is conveyed, the splash plate 6 moves axially to approach the dust removal port 21 to achieve conduction. After the feeding is stopped, the splash plate 6 automatically resets to seal the port to prevent the gravel from splashing outward.

[0042] During use, since the splash plate 6 is located at the inlet port, when the slag is transported, the splash plate 6 will be pushed to move axially, so that it is close to the dust removal port 21 to achieve conduction. When the slag contacts the hammer 37, it will be hammered and crushed by the rotating hammer 37, and the crushing cone wall 22 can further improve the crushing effect. Since the splash plate 6 partially blocks the inlet port, the crushed stone can be prevented from splashing out, and the dust generated by the crushing is led out through the suction fan 5, which can reduce the dust overflow and affect the working environment.
