Description

Technical Field

[0001] The utility model relates to the technical field of dust-proof net recovery, in particular to a building dust-proof net recovery device. Background Art

[0002] A construction dust net recovery device is a device designed specifically to address efficiency and convenience issues during the installation and recovery of dust nets on construction sites. This type of device typically combines mechanization and automation technologies to reduce manual labor and improve the efficiency and recovery of dust nets. With the continuous expansion of construction projects and increasing environmental protection requirements, the application prospects of construction dust net recovery devices are becoming increasingly broad. In the future, with the continuous advancement and innovation of technology, this type of device will become more intelligent, efficient, and environmentally friendly, making greater contributions to the sustainable development of the construction industry.

[0003] A search revealed that the utility model patent with publication number CN219929180U discloses a dust screen recycling device. While this utility model patent solves the problem in the prior art that the dust screen needs to be spread out by multiple people and then manually rolled up, and the rolling process requires manual flattening of the folded or uneven areas, requiring multiple people to work together, resulting in low recycling efficiency, this utility model patent has the following problems:

[0004] First, this utility model patent uses two support plates arranged in an inverted V-shaped structure to spread out the dust screen during the recycling process. Because the recycled dust screens are stacked on top of each other and squeezed for a long time, deep creases appear on the surface of the dust screen. As a result, the spread dust screen is not flat enough, affecting the rewinding effect.

[0005] Second, due to long-term squeezing, there are deep creases on the surface of the dustproof net, and the rolled dustproof net is relatively loose and not tight enough, which makes the dustproof net take up a lot of space and is not conducive to storage;

[0006] Therefore, a building dust-proof net recovery device is proposed. Utility Model Content

[0007] In view of this, the present invention provides a construction dust net recovery device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0008] The technical solution of the utility model is achieved as follows: a building dust net recovery device comprises a base, the upper surface of the base is fixedly connected to an N-shaped support frame, the top of the N-shaped support frame is fixedly connected to motor 1, the output end of the motor 1 is fixedly connected to a gear, the outer wall of the gear is meshed with rack 1 and rack 2, the lower surfaces of rack 1 and rack 2 are both provided with a slide groove, the inner wall of the slide groove is slidably connected to a limit rod, the bottom of the limit rod is fixedly connected to a support base plate, the support base plate is fixedly connected to the inner wall of the N-shaped support frame, the upper surfaces of rack 1 and rack 2 are both fixedly connected to the N-shaped stretching frame, the upper surface of the base is fixedly connected to an auxiliary block, the upper surface of the auxiliary block is abutted against the bottom of the N-shaped stretching frame, the upper surface of the base is provided with a connecting groove, the inner wall of the connecting groove is slidably connected to support block 1, the upper surface of the base is fixedly connected to support block 2, one side of the support block 2 is fixedly connected to motor 2, and the output end of the motor 2 is fixedly connected to the support rod, the outer wall of the support rod is sleeved with a support pipe, and the outer wall of the support pipe is provided with a through groove.

[0009] Further preferably, the upper surface of the base is fixedly connected to a supporting side plate, and the side of the supporting side plate close to the N-shaped support frame is fixedly connected to a telescopic rod and a spring, the spring is sleeved on the outer wall of the telescopic rod, and one end of the telescopic rod and the spring is fixedly connected to an arc-shaped push plate.

[0010] Further preferably, anti-skid particles are fixedly connected to the interior of the support tube, and the anti-skid particles are provided in multiple groups, and the multiple groups of anti-skid particles are evenly distributed on the inner wall of the support tube.

[0011] Further preferably, two groups of telescopic rods and springs are provided, and the two groups of telescopic rods and springs are symmetrically distributed.

[0013] Further preferably, the auxiliary blocks are provided in two groups, and the two groups of auxiliary blocks and the N-shaped stretching frame are symmetrically arranged.

[0014] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0015] First, the utility model adds a structure for unfolding the building dust net to the building dust net recovery device, thereby preventing the building dust net from curling. That is, when the motor rotates and drives the gear to rotate, the rack 1 and the rack 2 move in the direction away from the gear, respectively driving the N-shaped stretching frame to move in the direction away from the gear, thereby unfolding and tightening the curled building dust net to both sides. The generated tension straightens and flattens the folds, making the spread dust net smoother and the winding effect better.

[0016] 2. When the utility model is used to recover the building dust net, if you want to achieve a better rolling effect, start the second motor, and the second motor drives the support rod, the support tube and the building dust net to rotate, thereby rolling up the building dust net. In the rolling process, the arc-shaped push plate is tightly attached to one side of the building dust net under the cooperation of the telescopic rod and the spring, making the rolled-up building dust net tighter, taking up less space, and being convenient for storage.

[0027] In one embodiment, a support side plate 19 is fixedly connected to the upper surface of the base 1. A telescopic rod 20 and a spring 21 are fixedly connected to the side of the support side plate 19 near the N-shaped support frame 2. The spring 21 is sleeved on the outer wall of the telescopic rod 20. One end of the telescopic rod 20 and the spring 21 is fixedly connected to an arc-shaped push plate 22. Anti-slip particles 23 are fixedly connected to the interior of the support tube 17. The anti-slip particles 23 are provided in multiple groups, and the multiple groups of anti-slip particles 23 are evenly distributed on the inner wall of the support tube 17. The anti-slip particles 23 have an anti-slip effect, preventing the support tube 17 from rotating during the rewinding of the building dustproof net, which would affect the net rewinding efficiency.

The rotation of the motor 13 drives the gear 4 to rotate, and the rack 15 and the rack 26 move toward each other as the gear 4 rotates. When the rack 15 and the rack 26 move in the direction away from the gear 4, they respectively drive the N-shaped stretching frame 10 to move in the direction away from the gear 4, thereby unfolding the curled-up building dust net to both sides. With the cooperation of the auxiliary blocks 11, the N-shaped stretching frame 10 pushes the building dust net to gradually tighten the two sides of the building dust net during the movement, producing The generated pulling force straightens and flattens the creases, making the spread dust-proof net flatter and the rolling effect better; when one end of the building dust-proof net reaches the support rod 16, the staff wraps one end of the building dust-proof net around the outer wall of the support rod 16, and fixes one end of the building dust-proof net by clamping the support tube 17 to the outside of the building dust-proof net and the support rod 16, and then starts the motor 2 15, which drives the support rod 16, the support tube 17 and the building dust-proof net to rotate, thereby rolling up the building dust-proof net, and during the rolling process, the arc-shaped push plate 22 is close to one side of the building dust-proof net with the cooperation of the telescopic rod 20 and the spring 21, so that the rolled-up building dust-proof net is tighter, occupies less space, and is convenient for storage.
