Description

Technical Field

[0001] This utility model relates to the field of building dust removal technology, and in particular to a dust removal device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roofing construction, and decoration construction. Construction sites often generate a lot of dust, which can easily inhale by workers, seriously threatening their lives. Therefore, dust removal devices are needed at construction sites to reduce the dust content in the air. However, existing dust removal devices have limited coverage areas because the suction port is too close to the device itself, while extending the suction port outwards would require more space and be inconvenient for transportation and storage. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a dust removal device for building construction, which effectively solves the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a dust removal device for building construction, including a dust removal cylinder, a dust collection fan fixedly connected to the center of the dust removal cylinder, several collection slots opened on the outer side of the dust removal cylinder, a rotating block rotatably connected to the top of the collection slots, a lifting rod slidably connected to the middle of the rotating block, a dust collection funnel rotatably connected to the top of the lifting rod, a dust collection pipe fixedly connected to one side of the dust collection funnel, and one end of the dust collection pipe fixedly connected to the dust collection fan.

[0005] Optionally, the shape of the storage slot is adapted to the shape of the lifting rod, and a slot is provided on the inner side of the top of the storage slot. The shape of the slot is adapted to the shape of the bottom of the lifting rod, and the top of the slot is inclined outward.

[0006] The above technical solution involves providing a storage groove and a slot on the outside of the dust collection cylinder. The lifting rod can be retracted into the storage groove, allowing the dust collection funnel to fit snugly against the dust collection cylinder for dust collection. When it is necessary to expand the dust collection range, the lifting rod can be pulled out and its bottom inserted into the slot, causing the dust collection funnel to open diagonally upwards towards the dust collection cylinder, thereby expanding the dust collection range that the dust collection device can cover. This device can adjust the distribution range of the dust collection funnel as needed, reducing the space occupied during normal storage.

[0007] Optionally, the length of the lifting rod is less than the height of the dust collection cylinder, and the friction between the lifting rod and the collection slot is greater than the sum of the weights of a single dust collection funnel and a single dust collection pipe.

[0008] The above technical solution is adopted: by limiting the friction between the lifting rod and the storage slot, the lifting rod can be kept at the adjusted height under the action of friction when it is inserted into the storage slot, so that the dust collection funnel can be vertically raised and lowered to adjust the height and be kept at that height for dust collection.

[0009] Optionally, the top of the lifting rod is rotatably connected to a rotating shaft, and the lifting rod is rotatably connected to the dust collection funnel through the rotating shaft. The rotating shaft is a damping rotating shaft, and the resistance to the rotation of the rotating shaft is greater than the weight of the dust collection funnel.

[0010] The above technical solution is adopted: by setting a damping pivot between the lifting rod and the dust collection funnel, the dust collection angle of the dust collection funnel can be adjusted as needed, and the dust collection funnel can be kept at the adjusted angle under the action of damping resistance.

[0011] Optionally, the axis of the rotating block is located at the intersection of the storage groove and the card slot, and the diameter of the circular hole at the center of the rotating block is adapted to the diameter of the lifting rod.

[0012] The above technical solution is adopted: by setting a rotating block at the intersection of the storage slot and the card slot, the lifting rod can move more smoothly when it moves through the slot, making the adjustment of the state of the vacuum funnel simpler and faster.

[0013] Optionally, the suction funnel is connected to the suction fan via a suction pipe, and the suction pipe is a telescopic pipe.

[0014] The above technical solution is adopted: by setting the connecting pipe as a telescopic pipe, the suction pipe can be bent and extended as needed when the angle and height of the suction funnel are adjusted.

[0015] Optionally, the dust extraction fan has a dust outlet on one side of its bottom, and the dust outlet passes through the side of the dust collection cylinder.

[0016] The above technical solution is adopted: by setting a dust outlet at the bottom of the vacuum blower, it is convenient to clean the dust collected by adsorption, and the dust outlet and the dust funnel above can form an airflow channel for dust collection.

[0017] This utility model has the following advantages:

[0018] 1. This dust removal device for construction uses a collection slot and a locking slot on the outside of the dust collection cylinder. The lifting rod can be retracted into the collection slot, allowing the dust collection funnel to fit snugly against the dust collection cylinder for dust removal. When it is necessary to expand the dust collection range, the lifting rod can be pulled out and its bottom inserted into the locking slot, causing the dust collection funnel to open diagonally upwards towards the dust collection cylinder, thereby expanding the dust collection range that the dust removal device can cover. The device can adjust the distribution range of the dust collection funnel as needed, reducing the space occupied during normal storage. By limiting the friction between the lifting rod and the collection slot, the lifting rod can be kept at the adjusted height after insertion into the collection slot due to friction, thus allowing the dust collection funnel to be vertically raised and lowered and maintained at that height for dust removal.

[0019] 2. This dust removal device for construction uses a damping rotating shaft between the lifting rod and the dust collection funnel to allow the suction angle of the funnel to be adjusted as needed. Under the action of damping resistance, the funnel can be kept at the adjusted angle. By setting a rotating block at the intersection of the receiving slot and the card slot, the lifting rod can move more smoothly when moving through the slot, making the adjustment of the dust collection funnel simpler and faster. By setting the connecting pipe as a telescopic pipe, the suction pipe can be bent and extended as needed when adjusting the angle and height of the dust collection funnel.

[0020] 3. The dust removal device for construction uses a dust outlet at the bottom of the dust extraction fan to facilitate the cleaning of the collected dust, and the dust outlet and the dust extraction funnel above can form an airflow channel for dust extraction. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1 to 5 As shown, a dust removal device for construction includes a dust removal cylinder 1. A dust collection fan 2 is fixedly connected to the center of the dust removal cylinder 1. Several collection slots 3 are opened on the outer side of the dust removal cylinder 1. A rotating block 4 is rotatably connected to the top of the collection slots 3. A lifting rod 5 is slidably connected to the middle of the rotating block 4. A dust collection funnel 6 is rotatably connected to the top of the lifting rod 5. A dust collection pipe 7 is fixedly connected to one side of the dust collection funnel 6. One end of the dust collection pipe 7 is fixedly connected to the dust collection fan 2.

[0029] Example 1: The shape of the storage slot 3 is adapted to the shape of the lifting rod 5. A slot 8 is provided on the inner side of the top of the storage slot 3. The shape of the slot 8 is adapted to the shape of the bottom of the lifting rod 5. The top of the slot 8 is inclined outward. By providing the storage slot 3 and the slot 8 on the outside of the dust collection cylinder 1, the lifting rod 5 can be retracted into the storage slot 3, so that the dust collection funnel 6 fits in close contact with the dust collection cylinder 1 for dust collection and removal. When it is necessary to expand the dust collection range, the lifting rod 5 is pulled out and the bottom is inserted into the slot 8, so that the dust collection funnel 6 opens obliquely upward towards the dust collection cylinder 1, thereby expanding the dust collection range that the dust removal device can cover. The device can adjust the distribution range of the dust collection funnel 6 as needed, reducing the space occupied during normal storage.

[0030] Example 2: The length of the lifting rod 5 is less than the height of the dust collection cylinder 1. The friction between the lifting rod 5 and the collection slot 3 is greater than the sum of the weights of a single dust collection funnel 6 and a single dust collection pipe 7. By limiting the friction between the lifting rod 5 and the collection slot 3, the lifting rod 5 can be kept at the adjusted height under the action of friction when inserted into the collection slot 3. This allows the dust collection funnel 6 to be vertically raised and lowered to adjust its height and kept at that height for dust collection.

[0031] Example 3: The top of the lifting rod 5 is rotatably connected to a rotating shaft 9. The lifting rod 5 is rotatably connected to the dust collection funnel 6 through the rotating shaft 9. The rotating shaft 9 is a damping rotating shaft. The resistance to the rotation of the rotating shaft 9 is greater than the weight of the dust collection funnel 6. By setting a damping rotating shaft between the lifting rod 5 and the dust collection funnel 6, the dust collection angle of the dust collection funnel 6 can be adjusted as needed, and the dust collection funnel 6 can be kept at the adjusted angle under the action of the damping resistance.

[0032] Example 4: The axis of the rotating block 4 is located at the intersection of the storage groove 3 and the slot 8. The diameter of the circular hole at the center of the rotating block 4 is matched with the diameter of the lifting rod 5. By setting the rotating block 4 at the intersection of the storage groove 3 and the slot 8, the lifting rod 5 can move more smoothly when it moves through the groove, making the adjustment of the state of the vacuum funnel 6 simpler and faster.

[0033] Example 5: The vacuum funnel 6 is connected to the vacuum blower 2 through the vacuum pipe 7. The vacuum pipe 7 is a telescopic pipe. By setting the connecting pipe 7 as a telescopic pipe, the vacuum pipe 7 can be bent and extended as needed when the angle and height of the vacuum funnel 6 are adjusted.

[0034] Example 6: A dust outlet 10 is provided on one side of the bottom of the vacuum blower 2. The dust outlet 10 passes through the side of the dust collection cylinder 1. By setting the dust outlet 10 at the bottom of the vacuum blower 2, it is convenient to clean the dust collected by adsorption. The dust outlet 10 and the dust collection funnel 6 above can form an airflow channel for dust collection.

[0035] The working principle of this utility model is as follows:

[0036] S1. A storage groove 3 and a slot 8 are provided on the outside of the dust collection cylinder 1. The lifting rod 5 can be retracted into the storage groove 3, so that the dust collection funnel 6 fits in close contact with the dust collection cylinder 1 for dust collection. When it is necessary to expand the dust collection range, the lifting rod 5 is pulled out and the bottom is inserted into the slot 8, so that the dust collection funnel 6 can open diagonally upward to the dust collection cylinder 1, thereby expanding the dust collection range that the dust collection device can cover. The device can adjust the distribution range of the dust collection funnel 6 as needed, reducing the space occupied during normal storage.

[0037] S2. Limit the friction between the lifting rod 5 and the storage slot 3 so that when the lifting rod 5 is inserted into the storage slot 3, it can be maintained at the height after insertion and adjustment under the action of friction, so that the dust collection funnel 6 can be vertically raised and lowered to adjust the height and maintain it at the height for dust collection and removal, and maintain it at the appropriate height for dust collection and removal as needed.

[0038] Compared with the prior art, the present invention has the following advantages:

[0039] 1. This dust removal device for construction uses a collection groove 3 and a slot 8 on the outside of the dust collection cylinder 1. The lifting rod 5 can be retracted into the collection groove 3, allowing the dust collection funnel 6 to fit snugly against the dust collection cylinder 1 for dust removal. When it is necessary to expand the dust collection range, the lifting rod 5 can be pulled out and its bottom inserted into the slot 8, causing the dust collection funnel 6 to open diagonally upwards towards the dust collection cylinder 1, thereby expanding the dust collection range that the dust removal device can cover. The device can adjust the distribution range of the dust collection funnel 6 as needed, reducing the space occupied during normal storage. By limiting the friction between the lifting rod 5 and the collection groove 3, the lifting rod 5 can be kept at the adjusted height after insertion into the collection groove 3 under the action of friction, thus allowing the dust collection funnel 6 to be vertically raised and lowered and kept at that height for dust removal.

[0040] 2. This dust removal device for construction uses a damping rotating shaft between the lifting rod 5 and the dust collection funnel 6, which allows the dust collection angle of the dust collection funnel 6 to be adjusted as needed. Under the action of damping resistance, the dust collection funnel 6 can be kept at the adjusted angle. By setting a rotating block 4 at the intersection of the storage slot 3 and the card slot 8, the lifting rod 5 can move more smoothly when it moves through the slot, making the adjustment of the state of the dust collection funnel 6 simpler and faster. By setting the connecting pipe 7 as a telescopic pipe, the dust collection pipe 7 can be bent and extended as needed when the angle and height of the dust collection funnel 6 are adjusted.
