The core goal of green construction is to achieve "four savings and one environmental protection", namely energy saving, land saving, water saving, material saving and environmental protection.

[0003] A green dust-proof covering net for rapid hardening of temporary roads is disclosed in a Chinese utility model patent with publication number CN215236190U, comprising a collecting box, a collecting cavity is provided inside the collecting box, a rotating shaft is provided inside the collecting cavity, one end of the rotating shaft is rotatably connected to the collecting box, the other end of the rotating shaft extends out of the collecting box and is fixedly connected to a turntable, a collecting roller is fixedly connected to the rotating shaft, a dust-proof covering net body is sleeved on the collecting roller, a net outlet is provided on the side wall of the collecting box, one end of the dust-proof covering net body is fixedly connected to the collecting roller, the other end of the dust-proof covering net body extends out of the net outlet, and a water storage tank is fixedly connected to the upper end of the collecting box.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device is moved as a whole by universal wheels. When encountering strong winds or being subjected to external forces, the position of the collection box is prone to change, causing the position of the dustproof covering net body to shift. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a temporary road green construction dust prevention device.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a temporary road green construction dust prevention device, including a net collection box, a net outlet hole is formed through the side wall of the net collection box, a counterweight box is provided on the side wall of the net collection box, a rotating shaft rotatably connected to the net collection box is formed through the side wall of the net collection box, a hand wheel is fixed to the end of the rotating shaft away from the net collection box, a dustproof net is sleeved on the rotating shaft, one end of the dustproof net is fixed to the side wall of the rotating shaft, and the other end of the dustproof net passes through the net outlet hole and is fixed to the side wall of the counterweight box;

[0007] The side wall of the network collecting box is provided with a mounting frame which is slidingly connected to the side wall of the network collecting box, and four universal wheels distributed in a rectangular array are fixed to the bottom of the mounting frame. A lifting assembly for lifting the mounting frame is installed on the network collecting box, and the lifting assembly includes a mounting plate fixed to the side wall of the network collecting box, a threaded rod which is arranged on the mounting plate and threadedly connected, and a rotating block fixed to the upper end of the threaded rod, and the lower end of the threaded rod is rotatably connected to the upper surface of the mounting frame.

[0008] By adopting the above technical solution, when the dust-proof device needs to be used, the staff moves the network collection box to a suitable position through the universal wheel, adjusts the length of the dust-proof net by turning the rotating shaft through the hand wheel and covers the dust-proof net on the temporary road, and then rotates the threaded rod through the rotating block, so that the threaded rod drives the installation frame to move upward, and the universal wheel is separated from the contact with the ground upward, thereby reducing the probability of the position of the network collection box changing, thereby reducing the probability of the position of the dust-proof net shifting.

[0009] Furthermore, a non-slip pad is fixed on the bottom of the network collection box.

[0010] By adopting the above technical solution, the anti-skid pad is made of rubber material, and its surface has a large friction coefficient, which increases the friction at the bottom of the network collecting box and further reduces the probability of displacement of the network collecting box. In addition, the anti-skid pad also reduces the wear on the bottom of the network collecting box.

[0011] Furthermore, a limiting assembly for limiting the position of the rotating shaft is installed on the rotating shaft, and the limiting assembly includes a limiting nut sleeved on the rotating shaft and threadedly connected to the rotating shaft.

[0012] By adopting the above technical solution, after adjusting the length of the dust screen, the staff needs to tighten the limit nut so that the side wall of the limit nut is pressed against the side wall of the collection box, thereby limiting the rotating shaft and reducing the probability of the dust screen length changing due to automatic rotation of the rotating shaft.

[0013] Furthermore, an annular rubber sheet is sleeved on the rotating shaft and is located between the limiting nut and the network collecting box.

[0014] By adopting the above technical solution, the annular rubber sheet is made of rubber material, and its surface has a large friction coefficient. The limit nut cooperates with the network collecting box and presses against the annular rubber sheet, which increases the friction between the limit nut and the network collecting box and reduces the direct wear between the limit nut and the network collecting box.

[0015] Furthermore, a water inlet connected to the inner wall of the counterweight box is opened on the upper surface of the counterweight box, and a first sealing cover for closing the water inlet is provided on the water inlet; a water outlet connected to the inner wall of the counterweight box is opened on the side wall of the counterweight box, and a second sealing cover for closing the water outlet is provided on the water outlet.

[0016] By adopting the above technical solution, after adjusting the length of the dustproof net, the staff opens the first sealing cover and fills the counterweight box with water through the water filling port, thereby increasing the weight of the counterweight box and reducing the probability of displacement of the counterweight box; when the dustproof net is not needed, the staff opens the second sealing cover to discharge the water from the water outlet, thereby reducing the weight of the counterweight box and facilitating the staff to move the dustproof device.

[0017] Furthermore, the inner bottom wall of the counterweight box is arranged to be inclined downward toward the water outlet.

[0018] By adopting the above technical solution, the inclined bottom wall of the counterweight box allows water to flow toward the water outlet, which is conducive to the rapid outflow of water in the counterweight box after opening the second sealing cover.

[0019] Furthermore, a fixing block is fixed to the side wall of the network collection box, and a fixing groove which is plugged and matched with the fixing block is opened on the side wall of the counterweight box.

[0020] By adopting the above technical solution, when the dustproof net is not needed, the staff will plug the counterweight box into the fixed block so that the counterweight box can be stored on the net collection box, which is convenient for the staff to move the device.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the dust-proof device needs to be used, the staff moves the net collection box to a suitable position through the universal wheel, adjusts the length of the dust-proof net by rotating the rotating shaft through the hand wheel and covers the dust-proof net on the temporary road, and then rotates the threaded rod through the rotating block, so that the threaded rod drives the installation frame to move upward, so that the universal wheel is separated from the contact with the ground upward, reducing the probability of the position of the net collection box changing, thereby reducing the probability of the position of the dust-proof net shifting;

[0023] 2. In the present application, the anti-skid pad is made of rubber material, and its surface has a large friction coefficient, which increases the friction force at the bottom of the net collecting box, further reduces the probability of displacement of the net collecting box, and in addition, the anti-skid pad also reduces the wear of the bottom of the net collecting box;

[0024] 3. In this application, after adjusting the length of the dust screen, the staff needs to tighten the limit nut so that the side wall of the limit nut is pressed against the side wall of the collection box, thereby limiting the position of the rotating shaft and reducing the probability of the dust screen length changing due to automatic rotation of the rotating shaft.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0030] like Figure 1-3 As shown, an embodiment of the present application discloses a temporary road green construction dust prevention device, including a network collection box 1, a counterweight box 2, a rotating shaft 3, a hand wheel 4, a dust prevention net 5, an installation frame 6, a universal wheel 61 and a lifting assembly 7.

[0031] The net collecting box 1 is a rectangular box structure, and a mesh hole 101 is opened through the side wall of the net collecting box 1. The counterweight box 2 is a rectangular box structure, and the counterweight box 2 is arranged on the side wall of the net collecting box 1. The rotating shaft 3 is a horizontally arranged round rod-shaped structure, and the rotating shaft 3 is arranged through the side wall of the net collecting box 1 and is rotatably connected. The handwheel 4 is fixed to the end of the rotating shaft 3 away from the net collecting box 1, and the axis of the handwheel 4 coincides with the axis of the rotating shaft 3. The dustproof net 5 is sleeved on the rotating shaft 3, one end of the dustproof net 5 is fixed to the side wall of the rotating shaft 3, and the other end of the dustproof net 5 passes through the mesh hole 101 and is fixed to the side wall of the counterweight box 2. The mounting frame 6 is sleeved on the side wall of the net collecting box 1, and the mounting frame 6 is slidingly connected to the side wall of the net collecting box 1. The universal wheel 61 is fixed to the bottom of the mounting frame 6, and four universal wheels 61 are arranged and distributed in a rectangular array.

[0032] The lifting assembly 7 is installed on the net collecting box 1 and is used to lift the installation frame 6. The lifting assembly 7 includes a mounting plate 71, a threaded rod 72 and a rotating block 73. The mounting plate 71 is a rectangular plate-like structure, and the mounting plate 71 is fixed to the side wall of the net collecting box 1. The threaded rod 72 is a vertically arranged rod-like structure, and the threaded rod 72 is penetrated and arranged on the mounting plate 71 and is threadedly connected. The lower end of the threaded rod 72 is rotatably connected to the upper surface of the installation frame 6. The rotating block 73 is a round block-like structure, and the rotating block 73 is fixed to the upper end of the threaded rod 72, and the axis of the rotating block 73 coincides with the axis of the threaded rod 72.

[0033] When the dust-proof device is needed, the staff moves the network collecting box 1 to a suitable position via the universal wheel 61, adjusts the length of the dust-proof net 5 by rotating the rotating shaft 3 via the hand wheel 4 and covers the dust-proof net 5 on the temporary road, and then rotates the threaded rod 72 via the rotating block 73, so that the threaded rod 72 drives the mounting frame 6 to move upward, causing the universal wheel 61 to be out of contact with the ground upward, thereby reducing the probability of the position of the network collecting box 1 changing, thereby reducing the probability of the position of the dust-proof net 5 being offset.

[0034] In order to further reduce the probability of displacement of the network collecting box 1, an anti-skid pad 8 is fixed to the bottom of the network collecting box 1. The anti-skid pad 8 is made of rubber material and its surface has a large friction coefficient, which increases the friction force at the bottom of the network collecting box 1, thereby further reducing the probability of displacement of the network collecting box 1. In addition, the anti-skid pad 8 also reduces the wear on the bottom of the network collecting box 1.

[0035] In order to limit the position of the rotating shaft 3, a limiting assembly 9 is installed on the rotating shaft 3 for limiting the position of the rotating shaft 3. The limiting assembly 9 includes a limiting nut 91 and an annular rubber sheet 92. The limiting nut 91 is sleeved on the rotating shaft 3 and is threadedly connected to the rotating shaft 3. The axis of the limiting nut 91 coincides with the axis of the rotating shaft 3. The annular rubber sheet 92 is sleeved on the rotating shaft 3, and the annular rubber sheet 92 is located between the limiting nut 91 and the net collecting box 1. After adjusting the length of the dustproof net 5, the staff needs to tighten the limiting nut 91 so that the limiting nut 91 cooperates with the net collecting box 1 and presses against the annular rubber sheet 92, thereby limiting the rotating shaft 3, reducing the probability of the length of the dustproof net 5 changing due to the automatic rotation of the rotating shaft 3. The annular rubber sheet 92 is made of rubber material, and its surface has a large friction coefficient, which increases the friction between the limiting nut 91 and the net collecting box 1 and reduces the direct wear between the limiting nut 91 and the net collecting box 1.

[0036] In order to reduce the probability of displacement of the counterweight box 2, a water inlet 21 connected to the inner wall of the counterweight box 2 is provided on the upper surface of the counterweight box 2, and a first sealing cover 10 for closing the water inlet 21 is provided on the water inlet 21. A water outlet 22 connected to the inner wall of the counterweight box 2 is provided on the side wall of the counterweight box 2, and a second sealing cover 11 for closing the water outlet 22 is provided on the water outlet 22. After adjusting the length of the dustproof net 5, the staff opens the first sealing cover 10 to fill the counterweight box 2 with water through the water inlet 21, so that the weight of the counterweight box 2 increases, thereby reducing the probability of displacement of the counterweight box 2; when the dustproof net 5 is not needed, the staff opens the second sealing cover 11 to discharge water from the water outlet 22, thereby reducing the weight of the counterweight box 2 and facilitating the staff to move the dustproof device.

[0037] In order to facilitate the rapid outflow of water in the counterweight box 2, the inner bottom wall of the counterweight box 2 is inclined downward toward the water outlet 22. The inclined inner bottom wall of the counterweight box 2 allows water to flow toward the water outlet 22, which is conducive to the rapid outflow of water in the counterweight box 2 after opening the second sealing cover 11.

[0038] In order to facilitate the movement of the device, a fixed block 12 is fixed to the side wall of the network collection box 1, and a fixed groove 23 is opened on the side wall of the counterweight box 2 to be plugged into the fixed block 12. When the dustproof net 5 is not needed, the staff will plug the counterweight box 2 into the fixed block 12 so that the counterweight box 2 can be stored on the network collection box 1, thereby facilitating the staff to move the device.

[0039] The use principle of a temporary road green construction dust prevention device in this embodiment is: when the dust prevention device is needed, the staff moves the network collection box 1 to a suitable position through the universal wheel 61, adjusts the length of the dustproof net 5 by rotating the rotating shaft 3 through the hand wheel 4 and covers the dustproof net 5 on the temporary road, and then rotates the threaded rod 72 through the rotating block 73, so that the threaded rod 72 drives the installation frame 6 to move upward, so that the universal wheel 61 is separated from the contact with the ground upward, thereby reducing the probability of the position of the network collection box 1 changing, thereby reducing the probability of the position of the dustproof net 5 being offset.

[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
