Description
Technical Field
[0001] This utility model relates to the field of vacuuming equipment technology, and more specifically, to a vacuuming equipment for ground construction. Background Technology
[0002] In the field of ground construction, vacuuming equipment is widely used to maintain a clean construction environment and reduce dust pollution. Most existing vacuuming equipment for ground construction uses a method of fixing the dust collection structure and the suction structure to a carrier such as an electric vehicle. The suction structure is usually a fixed structure and does not have adjustability.
[0003] In actual use, this fixed structure has many drawbacks: when the equipment is not in operation and is moved or parked, the vacuuming structure occupies a large space, making it inconvenient to move the vehicle and limiting the parking space; in addition, the vacuuming structure of some vacuuming equipment can obstruct the driver's view, posing a safety hazard to operation and making it difficult to meet the diversified and efficient operation needs of ground construction. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a dust collection device for ground construction.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A dust collection device for ground construction includes an electric vehicle, on which a dust collection structure and a dust collection port connected to the dust collection structure are installed. The dust collection structure is U-shaped and covers the outside of the front of the electric vehicle, and is connected to the electric vehicle through a support structure so that the dust collection structure can be rotated along the outside of the front of the electric vehicle, and has two states: unfolding downward to contact the ground, or retracting upward into the front of the electric vehicle.
[0007] Furthermore, the above solution includes two sets of support structures symmetrically arranged on the electric vehicle. The support structure includes a first lug, which is disposed on the electric vehicle and rotatably connected to the vacuuming structure so that the vacuuming structure can perform a flipping action. The first lug is provided with a second lug, which is connected to the vacuuming structure in the storage state so that the vacuuming structure in the storage state is fixed in position.
[0008] Furthermore, in the above solution, the second lug is fixed to the dust collection structure by means of buckles, bolts, or pins.
[0009] Furthermore, the above solution includes a vacuuming structure comprising two sets of strips, each set of strips being connected to a support structure and located on the side of the electric vehicle's front end. The strips are provided with docking holes and fixing holes. The docking holes are connected to the first lug, and the fixing holes are connected to the fixing holes when the strips are retracted. A cleaning box is connected to the ends of both sets of strips. The cleaning box is located at the front of the electric vehicle's front end and is provided with an adsorption chamber. A strip brush is installed on the adsorption chamber, and the adsorption chamber is connected to an air inlet, which is connected to the vacuum port via a flexible hose.
[0010] Furthermore, the above scheme includes two sets of strip brushes, which are respectively disposed on the front and rear faces of the adsorption chamber.
[0011] Furthermore, the above solution includes two sets of casters installed on the front face of the cleaning box. These casters contact the ground during operation, improving the stability of the structure.
[0012] Furthermore, the above solution includes a roller brush rotatably mounted inside the adsorption chamber to work in conjunction with the strip brush, thereby improving the cleaning power and effect.
[0013] Furthermore, the above solution includes a roller brush with shafts extending to the outside of the cleaning box and connected to wheels. The wheels contact the ground, enabling the roller brush to rotate autonomously by the movement of an electric vehicle, further stirring up dust and debris on the ground and effectively improving cleaning efficiency and results.
[0014] Furthermore, the above solution includes a drive motor connected to the roller brush shaft, which significantly improves the cleaning efficiency and quality of cleaning dust and other debris on the ground.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This utility model uses an electric vehicle as a carrier. A U-shaped dust-collecting structure is mounted on the outside of the electric vehicle's front end via a support structure. This allows the dust-collecting structure to flexibly switch between a working state where it extends downwards to contact the ground for dust collection and a non-working state where it retracts upwards into the front of the electric vehicle to save space and facilitate relocation. Compared to traditional fixed-structure dust collection equipment, this greatly improves the flexibility of equipment use and can better adapt to the needs of different stages of construction. Furthermore, the ingenious design of the U-shaped dust-collecting structure ensures that its dimensions completely avoid obstructing the driver's line of sight during operation, effectively improving the safety of equipment operation and preventing accidents caused by obstructed vision. This provides a strong guarantee for safe ground construction operations. Attached Figure Description

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0024] A dust collection device for ground construction, see attached. Figure 1 - Appendix Figure 5 As shown, the device includes an electric vehicle 1, on which a dust collection structure 2 is installed. The dust collection structure 2 has a dust suction port 21. The electric vehicle 1 is also equipped with a dust suction structure 3 connected to the dust suction port 21. The above structure is a commonly used installation and connection structure for vacuum cleaners in the prior art, and will not be described in detail here. The improvement of this application is that the dust suction structure 3 is U-shaped and covers the outside of the front of the electric vehicle 1, and is connected to the electric vehicle 1 through a support structure 11, so that the dust suction structure 3 can be flipped along the outside of the front of the electric vehicle 1, and has two states: unfolding downwards to contact the ground, or retracting upwards into the front of the electric vehicle 1.
[0025] In its specific implementation, this application uses an electric vehicle 1 as a carrier. A U-shaped vacuuming structure 3 is connected to the electric vehicle 1 via a support structure 11 and covered outside the front of the electric vehicle 1. This allows the vacuuming structure 3 to flexibly switch between a working state where it is unfolded downwards to contact the ground for vacuuming operations, and a non-working state where it is folded upwards to save space and facilitate relocation. This combination of flexibility and efficiency is achieved. During operation, the vacuuming structure 3 covered by the front of the electric vehicle 1 is first unfolded downwards via the support structure 11 to contact the ground. Then, the power is turned on, and the dust collection structure 2 supplies power to the vacuuming structure 3, generating negative pressure. This draws dust and other debris from the ground and transports them to the dust collection structure 2. After the operation is completed, the support structure 11 is manipulated to flip the vacuuming structure 3 upwards and fold it back into the front of the electric vehicle 1, facilitating vehicle relocation or parking. In addition, the U-shaped vacuuming structure 3 has a compact design that sufficiently avoids obstructing the driver's line of sight from the front of the electric vehicle 1, ensuring that the driver's operation is not obstructed.
[0026] For the above scheme, please refer to the appendix. Figure 1 As shown, there are two sets of support structures 11 symmetrically arranged on the electric vehicle 1. Specifically, the support structure 11 includes a first lug 111, which is disposed on the electric vehicle 1 and rotatably connected to the vacuuming structure 3 so that the vacuuming structure 3 can perform a flipping action. The first lug 111 is provided with a second lug 112, which is connected to the vacuuming structure 3 in the storage state so that the vacuuming structure 3 in the storage state is fixed.
[0027] Among them, two sets of support structures 11 are symmetrically arranged on the electric vehicle 1. The first lug 111 is hinged to the U-shaped vacuuming structure 3, providing a fulcrum for the vacuuming structure 3 to rotate, so that it can be unfolded downward to contact the ground for vacuuming operations, or flipped upward. When the vacuuming structure 3 is flipped to the storage state close to the front of the vehicle, the second lug 112 on the first lug 111 is fixed to the vacuuming structure 3 by mechanical connection methods such as buckles, bolts, and pins, to prevent it from shaking during the driving of the electric vehicle 1 and to ensure the stable operation of the vacuuming structure 3 in both states.
[0028] For the above scheme, please refer to the appendix. Figure 1 Appendix Figure 2 and appendix Figure 3As shown, the vacuuming structure 3 includes two sets of strips 31, each set of which is connected to a support structure 11 and located on the side of the front of the electric vehicle 1. Each strip 31 has a docking hole 311 and a fixing hole 312. The docking hole 311 connects to a first lug 111 to allow the strip 31 to flip. The fixing hole 312 connects to the strip 31 when it is in the retracted state. A cleaning box 32 is connected to the ends of both sets of strips 31. The cleaning box 32 is located at the front of the electric vehicle 1 and has a suction chamber 321. The front end of the suction chamber 321... A set of strip brushes 323 is installed on the front and rear surfaces respectively. A roller brush 324 is rotatably installed inside the adsorption chamber 321. The adsorption chamber 321 is connected to an air port 322. The air port 322 is connected to the dust suction port 21 through a hose 33. So that when the electric vehicle 1 is moving, the strip brushes 323 and roller brushes 324 will lift up dust and other debris on the ground. The negative pressure generated in the adsorption chamber 321 will cause the lifted dust and other debris to enter the dust collection structure 2 through the air port 322 and the hose 33. In addition, two sets of universal wheels 34 are installed on the front surface of the cleaning box 32. The two sets of universal wheels 34 are in contact with the ground when in working condition.
[0029] In this system, two sets of strips 31 are connected to symmetrically arranged support structures 11. The flipping action is achieved by hinged connection between the docking holes 311 and the first lugs 111 on the strips 31. When stored, the fixing holes 312 are connected and fixed to the second lugs 112. During operation, the two sets of universal wheels 34 installed on the front of the cleaning box 32 of the electric vehicle 1 touch the ground, supporting the cleaning box 32 to maintain a suitable distance from the ground. When the electric vehicle 1 is moving, the strip brushes 323 on the front and rear faces of the cleaning box 32 and the internal roller brushes 324 raise dust and other debris on the ground. At the same time, the suction chamber 321 is under negative pressure because the air inlet 322 is connected to the dust suction port 21 through the hose 33. The raised dust and other debris are sucked into the air inlet 322 and then into the dust collection structure 2 through the hose 33 to complete the collection.
[0030] In addition, considering the cleaning effect, in some embodiments, refer to the attached document. Figure 4 As shown, the roller brush 324 has two rotating shafts that extend to the outside of the cleaning box 32 and are connected to the walking wheels 325. The walking wheels 325 are in contact with the ground. The friction force from the ground during the movement of the electric vehicle 1 drives the walking wheels 325 to rotate. The walking wheels 325 transmit the rotational power to the roller brush 324 through the rotating shafts, so that the roller brush 324 rotates synchronously. Thus, the roller brush 324 is driven to rotate autonomously by the movement of the electric vehicle 1, which further stirs up the dust and debris on the ground. Combined with the negative pressure of the adsorption chamber 321, the cleaning efficiency and effect are effectively improved.
[0031] In other embodiments, the roller brush 324 is connected to a drive motor (not shown in the figure) so that the drive motor can start and output power to drive the roller brush 324 to rotate at high speed, so that the roller brush 324 generates stronger friction and agitation with the ground. Compared with the passive rotation of the roller brush 324 driven by the electric vehicle 1, the actively rotating roller brush 324 can more efficiently lift up stubborn dust, debris and other debris from the ground. Combined with the negative pressure in the adsorption chamber 321, it greatly improves the cleaning efficiency and cleaning quality of dust and other debris on the ground.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
