Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , the present utility model provides a technical solution for a sand making device with a dust removal function: a sand making device with a dust removal function includes a main sand making machine body 1. The main sand making machine body 1 is the main component for crushing and making sand from stones. A dust-proof discharge bin 3 is fixedly connected to the bottom of the main sand making machine body 1, which is used to receive the materials after sand making and play a dust-proof role. An opening and closing dust-proof component 2 is arranged at the rear end of the dust-proof discharge bin 3. Through its opening and closing action, the sand making device can be in a relatively closed environment during discharging, preventing dust from spreading from the discharge port to the external air. A dust suction and filtration component 4 is arranged inside the dust-proof discharge bin 3, which is used to absorb and filter the dust generated during the sand making process and play a role in dust removal. An outlet is opened on the right side of the bottom end of the dust-proof discharge bin 3. Among them, the main sand making machine body 1 is a prior art and will not be elaborated here.

[0025] Please refer to Figure 2 , the opening and closing dust-proof component 2 includes a fixed support plate 24, and the fixed support plate 24 is fixedly connected to the left side of the rear end of the dust suction and filtration component 4. The entire opening and closing dust-proof component 2 provides support on the left side. A support door beam 22 is fixedly connected to the upper side of the right end of the fixed support plate 24. The support door beam 22 and the upper side of the front end of the fixed support plate 24 are jointly fixedly connected with a moving sliding component 25. The support door beam 22 provides a stable installation position for the moving sliding component 25. A moving door panel 21 and a connecting door panel 23 are slidably connected to the outer surface of the moving sliding component 25. The moving door panel 21 is L-shaped and the horizontal side is the top end. The moving door panel 21 and the connecting door panel 23 can jointly cover the outlet. The moving door panel 21 and the connecting door panel 23 can jointly move and cover the outlet through the connection and cooperation of the moving sliding component 25, so as to form a relatively closed space during discharging, effectively preventing dust from leaking from the outlet to the external air and playing a dust-proof role.

[0026] Please refer to Figure 3, the moving sliding component 25 includes an upper support sliding rod 251. Below the upper support sliding rod 251, there are lower support sliding rods 253 that are parallel up and down. Both ends of the upper support sliding rod 251 and the lower support sliding rods 253 are respectively fixedly connected to the upper side of the front ends of the support door beam 22 and the fixed support plate 24. The upper support sliding rod 251 passes through and is slidably connected to the top end in the vertical direction of the moving door panel 21. A upper moving rack 252 is fixedly connected to the bottom side in the horizontal direction of the moving door panel 21.

[0028] The upper support sliding rod 251 passes through the top end in the vertical direction of the moving door panel 21, so that the moving door panel 21 can slide on the upper support sliding rod 251; similarly, the lower support sliding rod 253 provides sliding support for the connecting door panel 23. The upper support sliding rod 251 and the lower support sliding rods 253 are parallel up and down and will not affect the sliding movement of the moving door panel 21 and the connecting door panel 23. When the moving door panel 21 slides, the upper moving rack 252 drives the connecting moving gear 254 to rotate.

The end of the connecting filtration component 42 that is inclined upward and away from the dust suction port 41 is fixedly connected to a receiving pipe 43. The filtered dust is transmitted through the receiving pipe 43. At the same time, the inclined connecting filtration component 42 can initially prevent the produced sand from entering the filtration system. The end of the receiving pipe 43 away from the connecting filtration component 42 is fixedly connected to an integration box 44. The integration box 44 is fixedly connected to the left side inner wall of the dust-proof discharge bin 3. The integration box 44 sucks the dust into the dust suction and filtration component 4 through the negative pressure inside through the dust suction port 41. Among them, the integration box 44 is prior art and will not be explained here.

[0030] Please refer toFigure 5 and Figure 6 The connection and filtration component 42 includes two connection pipes 421. The right end of the right connection pipe 421 is fixedly connected to the middle of the left end of the dust suction port 41, and the left end of the left connection pipe 421 is fixedly connected to the right end of the receiving pipe 43. A number of filter rings 422 are rotatably connected to the opposite sides of the two connection pipes 421. A connection groove 423 is provided at the left end of the filter ring 422, a connection edge 424 is fixedly connected to the right end of the filter ring 422, and a filter net 425 is fixedly connected to the middle of the filter ring 422.

[0031] Please refer to Figure 5 and Figure 6 The left connection pipe 421 can enter the connection groove 423, and the left end of the right connection pipe 421 can enter the connection edge 424. Adjacent two filter rings 422 are rotatably connected through the connection edge 424 and the connection groove 423. The leftmost and rightmost filter rings 422 are respectively rotatably connected to the opposite sides of the two connection pipes 421.

[0032] Through the mutual connection between the connection groove 423 and the connection edge 424, each component can rotate correspondingly, providing a basis for the adjustment of the filtration system. Driven by the rotation of the filter ring 422, the filter net 425 can be driven to rotate, changing the staggered gap between the filter nets 425, enabling the filtration system to more effectively block dust, preventing too small dust from passing through the filtration system, and at the same time reducing the situation of sand of the appropriate size being wrongly captured, improving the flexibility and effect of dust removal.

[0033] Working principle:

[0034] First, start the main body 1 of the sand making machine. The stones are crushed and made into sand in it, and the made sand falls into the dust-proof discharge bin 3. After the device starts working, close the opening and closing dust-proof component 2. The moving door plate 21 slides on the upper support slide bar 251. Through the meshing transmission of the upper moving rack 252, the connecting moving gear 254 and the support moving rack 255, drive the connecting door plate 23 to slide on the lower support slide bar 253. The moving door plate 21 and the connecting door plate 23 move together to cover the discharge port, making the sand making device in a relatively closed environment to prevent dust from leaking from the discharge port. The dust suction and filtration component 4 conducts dust suction and filtration work inside the dust-proof discharge bin 3. The dust is sucked in through the dust suction port 41, and the dust filtered by the rotatable filter ring 422 and the filter net 425 in the connection and filtration component 42 enters the integrated box 44 through the receiving pipe 43. The staggered gap of the filter net 425 can be adjusted according to the rotation of the filter ring 422 to block dust of different sizes.
