Description

Technical Field

[0001] The utility model relates to construction dust prevention, and specifically refers to a dust-proof cloth laying device. Background Art

[0002] In the fields of mines, construction, agriculture, etc., dust-proof cloths are widely used in scenarios such as material yards and temporary roads to inhibit dust diffusion. However, the existing dust-proof cloth laying devices have the following problems. Currently, most of the laying of dust-proof cloths is manual, and there are also simple frameworks with only wheels to improve the laying convenience. However, the winding and unwinding of the dust-proof cloth roll only rely on free unwinding. When dealing with a damaged dust-proof cloth roll during winding and unwinding, it is easy to tear it. This device can add a motor to achieve powered winding and unwinding, but the installation and disassembly of the dust-proof cloth roll are relatively troublesome. When the dust-proof cloth is laid on the construction site for a long time and encounters rainy weather, mud will caking on the dust-proof cloth and will be sandwiched in the dust-proof cloth roll during winding, increasing the weight of the dust-proof cloth roll and affecting handling. This dust-proof cloth roll will also affect subsequent use. The cloth roll with soil blocks is generally not used in the material yard to avoid soiling the materials and losing the dust-proof effect, affecting the subsequent use ability. In this case, manual cleaning is generally adopted, resulting in low work efficiency. Summary of the Utility Model

Detailed implementation manners

[0027] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0028] Combined with the attached Figure 1 and the attached Figure 3 As shown, a dust-proof cloth laying device includes a traveling frame 1, on which a winding and unwinding mechanism 2 is provided. Wheels are rotatably provided on both sides of the traveling frame 1. A traction frame 12 is hinged on the traveling frame 1. A lump-breaking mechanism 3 and a dust removal mechanism 4 are also provided on the traveling frame 1. The lump-breaking mechanism 3 breaks the soil blocks on the dust-proof cloth during winding. The dust removal mechanism 4 is arranged between the winding and unwinding mechanism 2 and the lump-breaking mechanism 3. The dust-proof cloth passes through both sides of the dust removal mechanism 4, and the dust removal mechanism 4 pats the dust-proof cloth to remove dust.

[0029] Combined with the attached Figure 2 、the attached Figure 5 、the attached Figure 6 and the attached Figure 7As shown in the figure, the lump-breaking mechanism 3 includes a lower pressing plate 31 fixed to the traveling frame 1 and an upper pressing plate 32 movably arranged on the traveling frame 1. The dust-proof cloth passes through the gap between the lower pressing plate 31 and the upper pressing plate 32. A plurality of through holes are provided on the lower pressing plate 31, and a plurality of ball tables 322 are provided at the bottom of the upper pressing plate 32. The lump-breaking mechanism 3 further includes two turntables 331 rotatably arranged on the traveling frame 1. A driving shaft 33 is provided at the eccentric position between the turntables 331. The driving shaft 33 is rotatably arranged on the upper pressing plate 32. The lump-breaking mechanism 3 further includes a turntable 34 rotatably arranged on the traveling frame 1. Connecting shafts 321 are provided at both ends of the upper pressing plate 32. An eccentric hole 341 for rotatably cooperating with the connecting shaft 321 is provided at the eccentric position of the turntable 34. The rotation radius of the connecting shaft 321 is equal to the rotation radius of the driving shaft 33.

[0030] Working principle of the lump-breaking mechanism 3: The external power drives the turntable 331 to rotate, driving the driving shaft 33 eccentrically connected thereto to perform a circular motion. Since the driving shaft 33 is hinged to the upper pressing plate 32, its eccentric motion is converted into the up-and-down reciprocating motion of the upper pressing plate 32. The above structure realizes the function of simply longitudinally stamping and crushing soil clods. After the upper pressing plate 32 contacts the soil clods, the squeezed soil clods are subject to the frictional resistance of the upper pressing plate 32 and the lower pressing plate 31, thereby affecting the continuous winding of the dust-proof cloth by the soil clods.

[0031] To solve the above problems, the upper pressing plate 32 is matched with the eccentric holes 341 of the turntable 34 through the connecting shafts 321 at both ends to form a second set of eccentric motions. The two sets of eccentric mechanisms move synchronously, adding a rotational motion to the reciprocating motion of the upper pressing plate 32, so that the upper pressing plate 32 rotates while maintaining a horizontal state, avoiding the upper pressing plate 32 with only a lifting motion from hindering the winding action of the winding and unwinding mechanism 2 on the dust-proof cloth when pressing the dust-proof cloth against the lower pressing plate 31. When the upper pressing plate 32 rotates and presses down, the ball tables 322 at its bottom press the soil clods on the dust-proof cloth against the lower pressing plate 31 to break up the lumps. The broken soil clods fall from the through holes on the lower pressing plate 31. The continuous movement of the dust-proof cloth enables the lumps in different areas to pass under the ball tables in sequence, realizing continuous cleaning.

[0032] Combined with the attached Figure 2 and the attached Figure 8As shown in the figure, the dust removal mechanism 4 includes a rotating shaft 41 which is rotatably arranged on the traveling frame 1. There is a second motor 14 on the traveling frame 1. A first grooved pulley 141 is provided at the output end of the second motor 14. A second grooved pulley 44 is provided at the end of the rotating shaft 41. A double grooved pulley 332 is provided at the end of the driving shaft 33. The first grooved pulley 141 and the double grooved pulley 332 are connected by belt drive. The second grooved pulley 44 and the double grooved pulley 332 are connected by belt drive. A plurality of collars 42 are provided on the rotating shaft 41. A plurality of rubber sheets 43 are evenly provided on the collars 42. Two second guide rollers 18 and a third guide roller 19 are rotatably arranged on the traveling frame 1. The third guide roller 19 is located directly above the rotating shaft 41. The two second guide rollers 18 are symmetrically arranged on both sides below the rotating shaft 41. The dust-proof cloth bypasses the second guide rollers 18 and the third guide roller 19. The end of the rubber sheet 43 contacts the dust-proof cloth.

[0033] Working principle of the dust removal mechanism 4: This mechanism is mainly used to remove the dust remaining on the surface of the dust-proof cloth. When the second motor 14 is started, it drives the first grooved pulley 141 at its output end to rotate. The first grooved pulley 141 drives the double grooved pulley 332 through a belt, and then drives the de-caking mechanism 3 to operate. The other side of the double grooved pulley 332 drives the second grooved pulley 44 through a belt, so that the rotating shaft 41 rotates synchronously. When the rotating shaft 41 rotates, it drives a plurality of collars 42 and the evenly distributed rubber sheets 43 to rotate at high speed. The end of the rubber sheet 43 contacts the dust-proof cloth. Through continuous beating and scraping actions, the dust and debris attached to the cloth fall off. Since the rubber sheet can be replaced with other sheet-shaped flexible materials, such as plastic soft sheets, etc., for beating the dust-proof cloth, the rotating direction of the rubber sheet is the same as the moving direction of the dust-proof cloth, avoiding damage to the warp and weft of the dust-proof cloth by the rubber sheet in the reverse state, forming small holes one by one;

[0034] In order to improve the dust removal effect of the dust-proof cloth, the dust-proof cloth passes through the two second guide rollers 18 and the third guide roller 19, forming an inverted "U" - shaped cloth - running path, so that the rubber sheet 43 beats the dust-proof cloth twice in one rotation. The dust and debris knocked down by the rubber sheet fall naturally due to gravity or air flow, and can be collected centrally in cooperation with a dust suction device or a collecting trough. The dust suction device can adopt a simple fan and exhaust pipeline, and the exhaust port is arranged beside the dust removal mechanism 4 to collect dust under negative pressure.

[0035] Combined with the attached Figure 3 and the attached Figure 4As shown in the figure, the winding and unwinding mechanism 2 includes a roller shaft 21. One end of the roller shaft 21 is provided with a fixed baffle 22, and the other end is inserted with a movable baffle 23. Rotary tables 24 are provided on the outer sides of both the fixed baffle 22 and the movable baffle 23. A plurality of rollers 16 are rotatably provided on the two side plates 11 of the walking frame 1. A longitudinal groove 15 for avoiding the roller shaft 21 is provided on the side plate 11 above the rollers 16. The rotary table 24 is placed on the plurality of rollers 16. A motor 13 is provided on the walking frame 1. The output end of the motor 13 is provided with a detachable plug table 131. A slot 27 for plugging and matching with the plug table 131 is provided on the outer side of the fixed baffle 22. After the plug table 131 is inserted into the slot 27, the motor 13 drives the roller shaft 21 to rotate. A limiting platform 25 is provided at the through hole of the movable baffle 23, and a limiting groove 26 for cooperating with the limiting platform 25 is provided at the end of the roller shaft 21. A guiding roller 17 is rotatably provided at the rear end of the walking frame 1.

[0036] Working principle of the winding and unwinding mechanism 2: This mechanism is used for the automatic winding and unwinding of the dust-proof cloth. By driving the roller shaft 21 to rotate through the motor, the unfolding or recycling of the cloth is realized. At the same time, a detachable baffle design is adopted, which is convenient for replacing or maintaining the dust-proof cloth roll. Pull out the movable baffle 23 from the end of the roller shaft 21, install the dust-proof cloth roll, then re-insert it into the roller shaft 21, and fix the position through the cooperation of the limiting platform 25 and the limiting groove 26. The longitudinal groove 15 on the side plate 11 provides an installation space for the roller shaft 21 to ensure that the cloth roll can be smoothly put in or taken out. The rotary tables 24 on the outer sides of the fixed baffle 22 and the movable baffle 23 are placed on the rollers 16 of the side plate 11 of the walking frame 1, so that the roller shaft 21 can rotate freely. The end of the dust-proof cloth bypasses the guiding roller 17 and extends out from the rear end of the walking frame 1. At this time, the walking frame 1 can be driven by a vehicle to move, and the dust-proof cloth is freely unwound to complete the free laying work. When winding or when power-driven unwinding is required, the plug table 131 is installed at the output end of the motor 13. When installing the roller shaft 21, the plug table 131 is plugged into the slot 27, so that the motor 13 drives the roller shaft 21 to rotate. The power-driven unwinding state is suitable for the situation where the dust-proof cloth is damaged, to avoid the dust-proof cloth being torn by the tension during free laying.

[0037] When the present utility model is specifically implemented, when unwinding and laying the dust-proof cloth, the roller shaft 21 is inserted into the dust-proof cloth roll, and then the rotary table 24 of the roller shaft 21 is placed on the rollers 16. The dust-proof cloth bypasses the guiding roller 17 and extends out from the rear end of the walking frame 1. The roller shaft 21 rotates freely or is driven by the motor 13 to realize the unwinding and laying work. When winding the dust-proof cloth, the empty roller shaft 21 is installed and driven by the motor 13. The motor 14 drives the lump-removing mechanism 3 and the dust-removing mechanism 4 to work. The lump-removing mechanism 3 breaks the soil clods on the dust-proof cloth, and the dust-removing mechanism 4 cleans the dust and debris on the dust-proof cloth, so that the dust-proof cloth wound by the roller shaft 21 does not carry a large amount of soil particles. On the one hand, the weight of the dust-proof cloth roll is reduced, which is convenient for handling and storage. On the other hand, the cleanliness of the surface of the dust-proof cloth is improved, and the appearance of subsequent re-laying is improved.

[0038] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design, without creative efforts, structural manners and embodiments similar to the technical solution without departing from the gist of the creation of the present utility model, they shall fall within the protection scope of the present utility model.
