[0022] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] See attached Figure 1 The device for monitoring the concentration of dust in a machine-made sand aggregate production line in this embodiment includes a mobile base 1. The mobile base 1 includes a base plate and mobile wheels fixedly installed at the four corners of the bottom of the base plate, so that the device is easy to move and the flexibility of the device is improved.

[0025] See attached Figure 1-Figure 3 A connecting frame 2 is fixedly installed in the middle position on the top of the mobile base 1, and a No. 1 reinforcement frame 13 is fixedly installed between the mobile base 1 and the connecting frame 2. The No. 1 reinforcement frame 13 enhances the connection strength between the mobile base 1 and the connecting frame 2. The connecting frame 2 is vertically arranged, and a No. 1 screw 3 is arranged inside the connecting frame 2. A mobile column 4 is threadedly connected to the No. 1 screw 3, and the width of the mobile column 4 is equal to the internal width of the connecting frame 2, thereby realizing the limitation of the mobile column 4, so that the mobile column 4 can move longitudinally along the connecting frame 2 during the rotation of the No. 1 screw 3.

[0026] See attached Figure 3A driving assembly 5 for driving the No. 1 screw rod 3 to rotate is provided on the connecting frame 2, and the driving assembly 5 includes a No. 1 bevel gear 501 fixedly mounted on the No. 1 screw rod 3, a frame 502 is fixedly mounted on the connecting frame 2, and a motor 503 is fixedly mounted on the frame 502, and the output shaft of the motor 503 is connected with a No. 2 bevel gear 504 meshing with the No. 1 bevel gear 501, and the motor 503 is connected to an external power supply. When in use, the operator turns on the motor 503, and the motor 503 drives the No. 2 bevel gear 504 to rotate. Since the No. 1 bevel gear 501 and the No. 2 bevel gear 504 are meshingly connected, the No. 1 bevel gear 501 rotates synchronously, thereby driving the No. 1 screw rod 3 to rotate, and then realizing the longitudinal movement of the movable column 4.

[0027] See attached Figure 4 and Figure 5 A receiving pad 6 is fixedly installed on the top of the mobile column 4, and a second reinforcement frame 14 is fixedly installed between the connecting frame 2 and the receiving pad 6. The second reinforcement frame 14 enhances the connection strength between the connecting frame 2 and the receiving pad 6. A dust concentration monitor 10 is arranged above the receiving pad 6. The dust concentration monitor 10 can use a dust monitor of model jtky-100. A bidirectional screw 7 is rotatably installed on the receiving pad 6. The bidirectional screw 7 is arranged horizontally. A number one hand wheel is fixedly installed at one end of the bidirectional screw 7. When using By turning hand wheel No. 1, the rotation of the bidirectional screw 7 can be realized. A guide rod 8 is also fixedly installed on the receiving pad 6. Specifically, two guide rods 8 are provided, and are respectively arranged on both sides of the bidirectional screw 7. Both sides of the bidirectional screw 7 are threadedly connected with moving blocks 9, thereby realizing the limitation of the moving blocks 9, so that the moving blocks 9 on both sides can move toward or away from each other during the rotation of the bidirectional screw 7. A limiting rod 11 is fixedly installed on the top of the moving block 9, and the limiting rods 11 on both sides move synchronously with the moving blocks 9 on both sides.

[0028] See attached Figure 5 The limiting rod 11 is an L-shaped structure, and a fixing assembly 12 is arranged on the top of the limiting rod 11. The fixing assembly 12 includes a No. 2 screw 1201 threadedly connected to the top of the limiting rod 11, a No. 2 handwheel 1202 is fixedly installed on the top of the No. 2 screw 1201, and a fixing block 1203 is fixedly installed on the bottom of the No. 2 screw 1201. When in use, the No. 2 handwheel 1202 is rotated to realize the movement of the No. 2 screw 1201 and the fixing block 1203.

[0029] Before using the device, the operator first places the dust concentration monitor 10 on the receiving pad 6 so that it is placed between the limit rods 11 on both sides, and then turns the No. 1 handwheel, which drives the bidirectional screw 7 to rotate. During the rotation of the bidirectional screw 7, the moving blocks 9 on both sides drive the limit rods 11 on both sides to move toward each other, thereby limiting the dust concentration monitor 10. Then the operator turns the No. 2 handwheel 1202 to move the No. 2 screw 1201 and the fixed block 1203 downward, thereby fixing the dust concentration monitor 10 from above. Under the joint action of the limit rods 11 on both sides and the fixed blocks 1203 on both sides, the stability of the dust concentration monitor 10 is fully guaranteed. When in use, the operator turns on the motor 503 according to the implementation situation to realize the longitudinal movement of the moving column 4, thereby realizing the longitudinal movement of the dust concentration monitor 10, which is convenient for monitoring dust concentrations at different heights, covering a wider monitoring range, and improving the accuracy and comprehensiveness of monitoring.

[0030] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
