Description

Technical Field

[0001] This utility model relates to the field of building drilling technology, specifically a building exterior wall drilling device for building engineering. Background Technology

[0002] Because building exterior walls are directly exposed to wind, rain, snow, and air pollutants, and are directly affected by natural climate, it is necessary to install exterior wall finishes to extend their service life. These finishes can prevent erosion from wind, rain, corrosive gases, and microorganisms, and to a certain extent, improve the durability and strength of the wall, thus extending its service life. Drilling holes in the exterior wall is required for anchoring the finish during installation. Currently, drilling is done using electric drills. However, electric drills generally generate a large amount of dust during this process, and existing drills typically lack a dust collection function, affecting the drilling work. Therefore, this invention proposes a building exterior wall drilling device to solve the aforementioned problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a drilling device for building exterior walls for construction engineering, which solves the problems mentioned in the background technology.

[0011] Beneficial effects

[0012] This utility model provides a drilling device for exterior walls in building construction. Compared with the prior art, it has the following advantages:

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a building exterior wall drilling device for construction engineering, including a drilling electric drill 1, a supporting circular plate 2 fixed on the outer periphery of the drilling electric drill 1, and a dust adsorption unit 3 arranged above the drilling electric drill 1.

[0020] The dust collection unit 3 includes a dust collection cylinder 31 fixed above the drilling drill 1. A negative pressure adsorption machine 32 is installed on one side of the dust collection cylinder 31. The air inlet of the negative pressure adsorption machine 32 is connected to the dust collection cylinder 31. An adsorption conduit 33 is fixedly inserted through the other side of the dust collection cylinder 31. Multiple suction heads 34 are fixedly inserted through the support circular plate 2 and are distributed in a ring at equal intervals. An annular tube 35 is provided on the side of the support circular plate 2. The multiple suction heads 34 are all connected to the annular tube 35. The adsorption conduit 33 is connected to the annular tube. A filter screen 36 is fixed on the inner wall of the dust collection cylinder 31. A cleaning unit 4 is provided on the dust collection cylinder 31 to clean the filter screen 36.

[0021] The support plate 2 is used to fix the suction head 34. The negative pressure adsorption machine 32 is connected to an external power source and controlled by a control switch. The filter screen 36 is used to filter dust in the airflow.

[0022] The cleaning unit 4 includes a drive shaft 41 rotatably mounted on the inner wall of the dust collection cylinder 31. Multiple drive plates 42 are fixed on the surface of the drive shaft 41. A notch baffle 43 is fixed on the inner wall of the dust collection cylinder 31. A connecting shaft 44 rotatably passes through the notch baffle 43. A first bevel gear 45 is fixed on the surface of the drive shaft 41. A second bevel gear 46 that meshes with the first bevel gear 45 is fixed on the surface of the connecting shaft 44. A sweeping strip 47 is fixed on the surface of the connecting shaft 44. Cleaning bristles 48 that contact the filter screen 36 are fixed on the side of the sweeping strip 47.

[0023] All components in the entire cleaning unit 4 are made of lightweight materials and can ensure a certain rigidity. Under negative pressure, the drive plate 42 can drive the transmission shaft 41 to rotate, and then the first bevel gear 45 and the second bevel gear 46 can drive the connecting shaft 44 to rotate, thereby driving the cleaning bristles 48 to brush along the surface of the filter screen 36 to clean, reducing the possibility of filter screen 36 clogging, and thus ensuring the normal operation of vacuuming.

[0024] A drive motor 5 is also fixed to the outside of the dust collection cylinder 31. The output shaft of the drive motor 5 passes through the dust collection cylinder 31 and is fixed to the end of the transmission shaft 41. A storage battery 6 is fixed above the drilling drill 1. The storage battery 6 is electrically connected to the drive motor 5 through wires.

[0025] The drive motor 5 can serve as a backup. When the airflow is insufficient to drive the drive plate 42, the drive motor 5 can be started to control the rotation of the transmission shaft 41. The battery 6 can provide power to the drive motor 5 and can be charged. When the drive motor 5 is off, the transmission shaft 41 can be rotated normally by airflow.

[0026] The surface of the dust collection cylinder 31 has a discharge port, and a sealing plug 7 is embedded in the discharge port. The air outlet of the negative pressure adsorption machine 32 is connected to a heat dissipation duct 8, and the end of the heat dissipation duct 8 is close to the heat dissipation port of the drilling electric drill 1.

[0027] The sealing plug 7 has good sealing performance at the contact point with the discharge port. The sealing plug 7 can be removed by friction installation, and the swept dust can be poured out in a concentrated manner. The airflow can flow out quickly through the heat dissipation duct 8 and spray towards the heat dissipation port of the drilling drill 1, which can achieve auxiliary heat dissipation for the motor of the drilling drill 1.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] In actual use, the drilling machine 1 drills normally. At this time, the negative pressure adsorption machine 32 can be started. Under the action of negative pressure, the dust generated by drilling enters the dust collection cylinder 31 through the dust suction head 34, the annular tube 35, and the adsorption conduit 33. Due to the obstruction of the notch baffle 43, the airflow can only flow through the area below the notch baffle 43. The dust is blocked by the filter screen 36. At this time, the drive plate 42 drives the transmission shaft 41 to rotate, and then through the cooperation of the first bevel gear 45 and the second bevel gear 46, the connecting shaft 44 is driven to rotate, so as to drive the cleaning bristles 48 to brush along the surface of the filter screen 36 to clean, reducing the possibility of filter screen 36 clogging. Finally, the airflow can be sprayed through the heat dissipation conduit 8 to the heat dissipation port of the drilling machine 1, which can achieve auxiliary heat dissipation of the motor of the drilling machine 1. To facilitate the removal of dust, the sealing plug 7 can be removed and the swept dust can be poured out.
