[0022] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the attached drawings.

[0023] An embodiment of the present utility model discloses a crusher for construction engineering.

[0024] The present utility model provides a crusher for construction engineering as Figures 1-3 shown, including

[0025] Base 1, one end of the top of base 1 is fixedly connected with body 2, a feed inlet 3 is opened at the top of body 2, a crushing device 4 is fixedly connected in the top cavity of body 2, rotating sleeves 5 are fixedly connected at both ends of the top cavity of body 2, a connecting rod 6 is rotatably connected in the cavities of the two rotating sleeves 5, connecting sleeves 7 are fixedly connected to both ends of the rod wall of connecting rod 6, a splash-proof baffle 8 is fixedly connected between the side walls of the two connecting sleeves 7, torsion springs 9 are sleeved on both ends of the rod wall of connecting rod 6, and both ends of the two torsion springs 9 are fixedly connected with connecting sleeve 7 and rotating sleeve 5 respectively. A separation mechanism is arranged in the bottom cavity of body 2, and a separation screen 10 is fixedly connected to the side wall. A garbage interception box 11 is slidably connected to the bottom of the cavity of body 2. A connection bin 12 is fixedly connected to the side wall of body 2. A feeding mechanism is arranged in the cavity of connection bin 12. A rotating door 13 is rotatably connected to one end of connection bin 12. By using the torsion springs 9 sleeved on both ends of connecting rod 6, when the splash-proof baffle 8 connected through connecting sleeve 7 at both ends of connecting rod 6 is pressed down under gravity and the stone enters body 2, due to the fact that both ends of torsion spring 9 are fixedly connected with connecting sleeve 7 and rotating sleeve 5, the splash-proof baffle 8 is elastically reset to intercept the flying stones during crushing. By using the arranged separation mechanism, the plastic garbage and dust in the stones falling after crushing on separation screen 10 are separated by blowing air, and fall into the garbage interception box 11 corresponding to the position of the exhaust port 17. The garbage interception box 11 filters and intercepts the solids, and the gas is discharged. The separated stones fall into the feeding mechanism through the inclined separation screen 10, thus solving the problems that the existing crusher for construction engineering is prone to stone splashing during the crushing process and cannot screen out the garbage in the stones.

[0026] In order to separate the plastic garbage and dust in the crushed stones, as Figure 1 and 2 shown, the separation mechanism includes a blower 14, a connecting pipe 15, a spray plate 16 and an exhaust port 17. A blower 14 is fixedly connected to the top of connection bin 12. A connecting pipe 15 is fixedly connected to the bottom of blower 14. One end of connecting pipe 15 passes through the side wall of body 2 and is fixedly connected with a spray plate 16. The spray plate 16 corresponds to the position of separation screen 10. An exhaust port 17 is opened at the bottom of body 1. The exhaust port 17 corresponds to the position of the garbage interception box 11. By using the spray plate 16 connected through connecting pipe 15 at one end of blower 14, and through the spray plate 16 provided with a plurality of spray holes, the crushed stones are blown. When the air is discharged through the exhaust port 17 at the bottom of body 1, it drives the dust and plastic garbage to flow towards the exhaust port 17 together, thereby separating the plastic garbage and dust in the crushed stones.

[0027] In order to facilitate feeding, as Figure 1 and 2As shown, the blanking mechanism includes a stone collection hopper 18 and an electric push rod 19. One end inside the cavity of the connection bin 12 is rotatably connected to the stone collection hopper 18, and the other end of the top of the base 1 is rotatably connected to the electric push rod 19. The other end of the electric push rod 19 is rotatably connected to one end of the bottom of the stone collection hopper 18. By using the stone collection hopper 18 rotatably connected to one end inside the cavity of the connection bin 12, when the electric push rod 19 at the bottom end contracts and pulls, the stone collection hopper 18 is tilted, and the crushed stones fall out by gravity.

[0028] In order to limit the rotation door 13 after it is closed, as Figure 1 and 2 shown, a jack 20 is opened at one end of the side wall of the rotation door 13, and a bolt 21 is fixedly connected to the top of the connection bin 12. One end of the bolt 21 is inserted into the jack 20. By using the bolt 21 provided at the top of the connection bin 12 and inserting it into the jack 20 opened at one end of the rotation door 13, the rotation door 13 is limited after it is closed.

[0029] And in order to intercept and separate plastics waste, dust, etc., as Figures 1-3 shown, the waste interception box 11 is a frame body and is provided with a filter non-woven fabric at the bottom. By using the waste interception box 11 which is set as a frame body and is provided with a filter non-woven fabric at the bottom, while the gas is discharged through the filter non-woven fabric, the plastics waste and dust are intercepted and stored.

[0030] Finally, in order to facilitate the movement of the device, as Figure 1 and 2 shown, a plurality of universal wheels 22 are fixedly connected to the bottom of the base 1. By using the plurality of universal wheels 22 provided, the device can be easily moved.

[0031] Working principle:

[0032] In use, the stone material is put into the feeding port 3 through devices such as a feeding machine. The stone material falls onto the splash-proof baffles 8 at both ends. Due to the principle of gravity, it generates downward pressure to make the stone material enter the machine body 2. Then, through the torsion springs 9 arranged at both ends of the rod wall of the connecting rod 6, both ends of the torsion spring 9 are fixedly connected to the connecting sleeve 7 and the rotating sleeve 5. When the gravity is lost, the splash-proof baffle 8 is elastically reset to intercept the splashing stone material during crushing. By using the provided separation mechanism, air is blown out to the stone material that has fallen after crushing. When the air is discharged through the exhaust port 17 at the bottom of the machine body 1, it will drive the dust and plastic waste to flow towards the exhaust port 17 together and fall into the garbage interception box 11 corresponding to the position of the exhaust port 17. By using the garbage interception box 11 which is set as a frame body and has a filter non-woven fabric at the bottom, while the gas is discharged through the filter non-woven fabric, the plastic waste and dust are intercepted and stored. The separated stone material falls into the feeding mechanism through the inclined separation screen 10. By pulling out the pin 21 and rotating to open the rotating door 13, the stone material is discharged through the feeding mechanism, thus solving the problems that the existing crusher for construction engineering is prone to splashing stone materials during the crushing process and cannot screen out the garbage in the stone materials.

[0033] Only some exemplary embodiments of the present invention have been described in the above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
