Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, and in particular to a building drilling machine. Background Technology

[0002] A building drilling machine is a mechanical device used for drilling holes in building construction. It is primarily used to drill holes in building structures for tasks such as soil sampling, installing embedded parts, and laying pipelines. Building drilling machines typically operate by rotating a drill bit to drill holes in underground rock and soil.

[0003] Existing building drilling machines, such as the Chinese utility model with application number CN202420555219.7, use a screw to rotate and a slider to generate threaded transmission. This causes the slider to move the limiting block and the drilling machine body towards the first anti-slip layer, while the drill bit drills a hole in the wall. The stepless adjustment characteristic of the threaded transmission allows for the movement of the drill bit to assist drilling. However, it still has the following drawbacks:

[0004] 1. When drilling multiple holes in a wall, it cannot move smoothly, ensuring that the drilling machine can drill multiple holes perpendicular to the wall.

[0005] 2. The dust generated during drilling cannot be collected quickly, which has an adverse impact on the surrounding environment.

[0006] This utility model addresses these issues by proposing a building drilling machine that solves the aforementioned problems, enabling the drilling machine to continuously drill holes at different locations on the wall with good perpendicularity between the holes and the wall, and preventing the spread of smoke and dust during the drilling process. Utility Model Content

[0007] In view of the above-mentioned shortcomings in the prior art, this utility model provides a building drilling machine.

[0008] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0009] A building drilling machine includes a base plate and a drill bit.

[0010] A top plate is provided above the base plate, and the top plate is connected to the base plate by a support rod. Self-locking casters are provided at the four corners of the lower end face of the base plate.

[0011] A vertical plate is provided at one end of the top plate, and an installation plate is provided above the top plate and perpendicular to it. A movable plate is provided between the installation plate and the vertical plate. A driving component is provided on the installation plate. The driving component drives the movable plate to move between the installation plate and the vertical plate. A drill bit is rotatably connected to the side of the movable plate facing the vertical plate. A speed reducer and a motor are provided on the side of the movable plate away from the vertical plate. The motor drives the drill bit to rotate through the speed reducer.

[0012] The drill bit is provided with a dust collection sleeve on its outer side. The dust collection sleeve is connected to the movable plate through a clamping assembly. When the drill bit is drilling, the clamping assembly keeps the dust collection sleeve tightly against the wall. The vertical plate is provided with a through hole for the dust collection sleeve to pass through.

[0013] The lower end face of the top plate is provided with a dust collection component, which is connected to the dust collection sleeve.

[0014] As an improvement, the drive assembly includes a second motor, a screw, and a guide rod. The screw and guide rod are provided between the mounting plate and the vertical plate. The screw is rotatably connected to the vertical plate, and the guide rod is fixedly connected to the vertical plate. The second motor is provided on the mounting plate, and the second motor drives the screw to rotate. The screw is threadedly connected to the movable plate, and the guide rod is slidably connected to the movable plate.

[0015] As an improvement, the clamping assembly includes a limiting rod and a spring. The limiting rod is symmetrically provided on the back of the dust collection sleeve. The limiting rod is slidably connected to the mounting plate. A spring is provided between the dust collection sleeve and the mounting plate.

[0016] As an improvement, the spring is sleeved on the outside of the limiting rod.

[0017] As an improvement, the dust collection assembly includes a dust collection box, a negative pressure fan, and a hose. The dust collection box is located on the lower end face of the top plate, and the negative pressure fan is located on the upper side of the dust collection box. The dust collection box is connected to the dust collection sleeve through the hose. The top plate has a slot, and the hose passes through the slot.

[0018] As an improvement, ball bearings are rolled at the four corners of the side of the vertical plate away from the mounting plate.

[0019] As an improvement, the support rod is a telescopic rod.

[0020] Compared to traditional technologies, the advantages of this utility model are:

[0021] 1. When drilling multiple holes in the wall, move the base plate and adjust the length of the support rod to adjust the position. During the position adjustment, the ball bearings on the vertical plate are connected to the wall to ensure the stability of the vertical plate movement and to ensure that the vertical plate is parallel to the wall, thereby ensuring that the drilled hole is perpendicular to the wall.

[0022] 2. During the drilling process, the dust collection sleeve is pressed against the wall by the clamping component to prevent the dust generated during drilling from spreading everywhere. At the same time, the dust collection component is activated to collect the dust generated during drilling to prevent it from affecting the surrounding environment. Attached Figure Description
