Description

Technical Field

[0001] This utility model relates to the field of floor cutting technology, and in particular to a cutting device for garage floor construction. Background Technology

[0002] In the construction of garage flooring, joint cutting is crucial. Joint cutting effectively prevents irregular cracks from forming due to temperature changes and concrete shrinkage, thus ensuring the overall quality and lifespan of the flooring. However, existing garage floor joint cutting devices have several drawbacks. First, the cutting process generates a large amount of dust, permeating the entire construction area and severely affecting visibility, interfering with workers' vision, increasing the difficulty and risk of operations, and causing serious environmental pollution that harms workers' health. Furthermore, because dust is more suspended and mobile in the air, the dust collection system needs to expend more energy and time to capture and collect it, increasing its workload, reducing efficiency, and leaving some dust in the air. Second, some joint cutting devices struggle to precisely control the cutting depth, resulting in inconsistent depths and affecting the flooring's crack-resistant properties. To address these issues, we propose a joint cutting device for garage floor construction. Utility Model Content

[0003] The main objective of this invention is to provide a cutting device for garage floor construction, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A cutting device for garage floor construction includes a frame. An opening is located at the center of the top of the frame, and a dust-collecting mechanism is slidably connected thereto. The dust-collecting mechanism includes an upper dust cover. First fixing plates are fixedly connected to both ends of the upper dust cover. Multiple sets of springs are installed at the bottom of the first fixing plates. Guide plates are fixedly connected to the other ends of the springs through the frame. Lower dust covers are installed at corresponding ends of the guide plates. The outer wall of the lower dust cover is slidably connected to the outer wall of the upper dust cover. Multiple reinforcing rods are installed at the top of the guide plates, penetrating the frame and the first fixing plates. The reinforcing rods are located inside the springs, and the outer wall of the top of the reinforcing rod is slidably connected to the first fixing plate.

[0006] Preferably, a lifting mechanism is provided at the center of the top of the vehicle frame. The lifting device includes a support frame, and a top plate is provided at the top of multiple sets of support frames. Threaded rods are rotatably connected to the front and rear sides of the top of the top plate. Fixed frames are provided at both the front and rear ends of the upper dust cover. The outer walls of multiple sets of threaded rods are threadedly connected to multiple sets of fixed frames.

[0007] Preferably, a drive shaft is rotatably connected to the center of the top of the top plate, a motor is provided at the top of the drive shaft, the bottom ends of multiple sets of threaded rods are rotatably connected to the top of the frame, and a drive bar is rotatably connected to the outer wall of the multiple sets of threaded rods and the outer wall of the drive shaft.

[0008] Preferably, a spraying mechanism is provided on the top left side of the vehicle frame. The spraying mechanism includes a water tank. A water pump is provided below the right end of the water tank. A water supply pipe is provided at the output end of the water pump. The other end of the water supply pipe passes through the vehicle frame and is fixedly connected to the left end of the lower dust cover. The water supply pipe is made of a retractable flexible hose.

[0009] Preferably, a conveying trough is provided inside the left end of the lower dust cover, and the conveying trough is connected to the water supply pipe. Multiple sets of sprayers are provided below the left end of the inner side of the lower dust cover, and all sets of sprayers are connected to the conveying trough.

[0010] Preferably, the top right side of the upper dust cover has an opening and a second suction pipe is fixedly connected thereto. The top right side of the frame has a collection box with a drawer detachably connected inside. The top of the collection box has an opening and a first suction pipe is fixedly connected thereto. The other end of the first suction pipe is equipped with an air pump, and the output end of the air pump is fixedly connected to the other end of the second suction pipe.

[0011] Preferably, a cutting device is provided on the inner side of the upper dust cover, multiple sets of universal wheels are provided at the four corners of the bottom of the frame, and a handlebar is provided on the right end of the frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This cutting device for garage floor construction, after the air pump is started, creates negative pressure in the first and second suction pipes. This causes the air and dust in the upper and lower dust covers to be sucked into the collection box through the second suction pipe under the pressure difference. The coordinated design of the upper and lower dust covers, and the connection of the lower dust cover to the frame via a spring, allows it to fit tightly against the floor surface during the cutting process, effectively collecting the dust generated during cutting. At the same time, the water pump draws water from the water tank and delivers it to the conveying trough inside the left end of the lower dust cover through a flexible hose. The conveying trough distributes the water to multiple sprayers. The sprayers atomize the water and spray it onto the cutting area. The atomized water comes into contact with the dust generated during cutting, causing the dust particles to agglomerate, increasing the weight of the dust, reducing its suspension in the air, and facilitating collection by the dust collection mechanism, thereby effectively reducing dust dispersion.

[0014] 2. This is a cutting device for garage floor construction. The motor drives the drive shaft to rotate, and the drive shaft drives the threaded rod on the top plate to rotate synchronously through the drive bar. Since the threaded rod is threadedly connected to the fixing brackets at the front and rear ends of the upper dust cover, when the threaded rod rotates, the fixing brackets will move up and down along the threaded rod, thereby driving the upper dust cover and the cutting device installed inside the upper dust cover to move up and down together, thereby achieving precise adjustment of the cutting depth.

[0026] Specifically, the operation of motor 3 drives the transmission shaft 31 to rotate, and the transmission shaft 31 drives multiple sets of threaded rods 32 on the top plate 34 to rotate through the transmission bar 33.

[0027] In this embodiment, a spraying mechanism is provided on the top left side of the frame 1. The spraying mechanism includes a water tank 5.

[0028] Specifically, the water pump 51 is started, and the water pump 51 transports the water in the water tank 5 to the conveying trough 53 inside the lower dust cover 41 through the water pipe 52.

[0029] In this embodiment, a conveying trough 53 is provided inside the left end of the lower dust cover 41. The conveying trough 53 is connected to the water pipe 52. Multiple sets of sprayers 54 are provided below the left end of the inner side of the lower dust cover 41. All sets of sprayers 54 are connected to the conveying trough 53.

[0030] Specifically, water is distributed to multiple sprayers 54 via a conveying trough 53. The sprayers 54 atomize the water and spray it onto the cutting area to begin dust suppression.

[0031] In this embodiment, the top right side of the upper dust cover 4 has a hole and a second suction pipe 24 is fixedly connected thereto.

After the vacuuming is finished, the drawer 21 in the collection box 2 is carefully pulled out, and the dust collected in the drawer 21 is cleaned. After cleaning, the drawer 21 is put back into the collection box 2.

[0033] In this embodiment, a cutting device 13 is provided inside the upper dust cover 4, multiple sets of universal wheels 11 are provided at the four corners of the bottom of the frame 1, and a handlebar 12 is provided at the right end of the frame 1.

[0034] Specifically, the operator holds the handlebars 12 and pushes the cutting device to move on the garage floor using the casters 11 at the four corners of the bottom of the frame 1.

[0035] It should be noted that this utility model is a cutting device for garage floor construction.

The operator holds the handle 12 and pushes the cutting device on the garage floor using the casters 11 at the four corners of the bottom of the frame 1. At this time, the cutting device 13 installed inside the upper dust cover 4 performs cutting operations on the floor. During the cutting process, the dust collection mechanism plays a role. The upper and lower dust covers work closely together, and the lower dust cover 41 maintains a good fit with the floor surface under the elastic action of multiple springs 44, effectively collecting the dust generated during cutting. At the same time, the water mist continuously sprayed by the sprayer 54 combines with the dust, making it easier for the dust to be collected by the dust collection mechanism and reducing the diffusion of dust in the air. After the cutting operation is completed and the equipment has cooled down, the drawer 21 in the collection box 2 is carefully pulled out and the dust collected in the drawer 21 is cleaned. After cleaning, the drawer 21 is put back into the collection box 2.
