Description

Technical Field

[0001] This utility model relates to the technical field of equipment for repairing walls in houses, and in particular to a drilling machine for repairing walls in houses. Background Technology

[0002] As houses are used over time, cracks and leaks may appear in the walls, requiring timely repairs. During repairs, in order to completely resolve the cracks and leaks, it is necessary to use a drill to drill holes in the walls so that grout can be used to fill the cracks.

[0003] Drilling generates a large amount of dust. Due to the relatively enclosed nature of buildings and poor air circulation, the dust continuously floats and forms airborne dust. Inhaling this dust can affect the health of construction workers. Moreover, the dust is scattered throughout the building, requiring significant time for cleaning after repairs. To address this, drilling rigs are typically equipped with compressible dust covers that fit over the drill bit chuck. During drilling, the dust cover presses against the wall to create a closed dust collection space. As the drill bit feeds, the dust cover compresses and deforms accordingly. Although this dust cover effectively collects dust, its limited internal space means that excessive dust accumulation can prevent it from compressing and deforming further, hindering continuous drilling and chip removal, thus affecting drilling quality. Utility Model Content

[0004] The purpose of this invention is to provide a drilling machine for repairing walls in houses. This drilling machine can concentrate and absorb dust, avoid dust generation and dust accumulation, thereby ensuring continuous drilling and improving the quality of wall drilling during house repairs.

[0008] Based on the above technical solution, the present invention can be improved as follows:

[0009] Furthermore, the drilling rig body has a power chamber for accommodating the power component, a dust collection chamber for accommodating the dust collection mechanism, and a transmission channel connecting the power chamber and the dust collection chamber.

[0010] One of the power output ends of the power component extends outside the drill body and drives the drill bit clamp, while the other power output end of the power component is connected to the dust collection mechanism at the transmission channel.

[0011] Furthermore, the drilling rig body is provided with a dust inlet, which is connected to the dust suction chamber; a dust suction pipe is connected to the dust inlet, and the end of the dust suction pipe is connected to the dust collection hood; the drilling rig body is provided with an exhaust port that is connected to the power chamber.

[0012] Furthermore, the dust collection mechanism includes a first filter element with one side opposite to the dust inlet on the drill body, a second filter element disposed above the first filter element, and a negative pressure element disposed on one side of the second filter element;

[0013] The negative pressure component is connected to the power output end of the power component at the transmission channel. The negative pressure component can form an airflow in the drilling rig body that passes sequentially through the dust inlet, dust suction chamber, first filter, second filter, transmission channel, power chamber and exhaust port.

[0014] Furthermore, a first dust collection space is formed between the first filter element and the inner wall of the dust collection chamber, and a second dust collection space is formed inside the first filter element. The second filter element is attached to the inner wall of the dust collection chamber. The first filter element is provided with a partition at the top for sealing the top opening of the first dust collection space. The partition isolates the first dust collection space from the second filter element. The second dust collection space is connected to the second filter element, so that the airflow passes through the first dust collection space, the second dust collection space and the second filter element in sequence.

[0015] Furthermore, the first filter element includes a cylindrical first support, a first filter screen covering the periphery of the first support, and a baffle that closes the bottom end of the first support. The top end of the first support forms an opening and communicates with the second filter element.

[0016] Furthermore, the second filter element includes a cylindrical second support and a second filter screen disposed at the bottom end of the second support. The mesh density of the second filter screen is greater than that of the first filter screen. The bottom end of the second support is connected to the top opening of the first support, the top end of the second support is closed, one circumferential side of the second support is in contact with the inner wall of the dust collection chamber, and the other circumferential side of the second support is provided with a vent hole.

[0017] Furthermore, the negative pressure component includes a rotating shaft rotatably disposed in the dust collection chamber, the rotating shaft being opposite to the vent hole on the second bracket, and the axis of the rotating shaft being perpendicular to the axis of the second bracket;

[0020] Furthermore, one side of the cover is rotatably connected to the dust outlet side of the drilling rig body, and the other side of the cover is a free side that can rotate relative to the drilling rig body around the rotatable connection; a locking assembly is provided between the free side of the cover and the other side of the dust outlet of the drilling rig body, which can lock with the dust outlet when the cover is closed.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] This invention features a dust collection hood mounted on the main body of the drill rig, which is fitted over the drill bit chuck. The hood effectively collects dust generated during drilling, preventing dust from being stirred up. Simultaneously, a suction mechanism connected to the dust collection hood is incorporated, along with a power unit with two output ends within the drill rig body. One output end of the power unit drives the drill bit chuck, while the other drives the suction mechanism. When the power unit is activated, it rotates the drill bit chuck, causing the clamped drill bit to drill, and simultaneously drives the suction mechanism to draw in the dust collected within the dust collection hood. This prevents excessive dust accumulation, ensuring continuous drilling and improving the quality of wall drilling during house repairs. Furthermore, the absence of an additional drive unit for the suction mechanism reduces the overall size and weight of the drill rig, making it easier to carry and operate by hand.

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. These descriptions are intended to aid in understanding the utility model but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] See Figures 1 to 4 This embodiment relates to a drilling machine for repairing walls in a house, including a drilling machine body 1, a drill bit chuck 2 mounted on the drilling machine body 1 for holding a drill bit, a dust collection hood 3 sleeved outside the drill bit chuck 2, a dust collection mechanism connected to the dust collection hood 3, and a power component mounted inside the drilling machine body 1 for generating power; the power component has two power output ends, one of which extends outside the drilling machine body 1 and drives and connects to the drill bit chuck 2, and the other power output end drives and connects to the dust collection mechanism, so that the drill bit chuck 2 can drive the held drill bit to rotate to drill a hole in the wall, and the dust generated during drilling is collected by the dust collection hood 3, and the dust collection mechanism can be activated to generate suction when the drill bit is drilling to absorb the dust in the dust collection hood 3.

[0032] Specifically, one end of the drill body 1 is a gripping end and is equipped with a handle 4. A switch 5 is provided on the handle 4 to control the start and stop of the power component. The other end of the drill body 1 is the drilling end. The drill bit chuck 2 is rotatably mounted on the drilling end of the drill body 1. The dust collection hood 3 is detachably connected to the drilling end of the drill body 1 and is fitted over the drill bit chuck 2. By gripping the handle 4, force is applied to the drill body 1 so that the dust collection hood 3 can abut against the wall surface to form a closed dust collection chamber when the drill bit is drilling, so as to concentrate the dust generated during drilling and thus effectively prevent dust from being stirred up.

[0033] The drilling rig body 1 includes two interconnected semi-shells. When assembled, the two semi-shells form a power chamber 6 for housing the power component, a dust collection chamber 7 for housing the dust collection mechanism, and a transmission channel 8 connecting the power chamber 6 and the dust collection chamber 7. One of the power output ends of the power component extends from the drilling end of the drilling rig body 1 and drives and connects to the drill bit chuck 2. The other power output end of the power component is connected to the dust collection mechanism through a transmission component at the transmission channel 8, so that when the power component provides power to the drill bit chuck 2, it can also provide power to the dust collection mechanism, thereby driving the drill bit chuck 2 and the dust collection mechanism simultaneously. This facilitates the collection of dust during drilling and effectively prevents a large amount of dust from accumulating in the dust collection hood 3.

[0034] The drilling rig body 1 has a dust discharge port on its bottom side, which is connected to the dust suction chamber 7. A closable cover 9 is provided at the dust discharge port, which is used to close or open the dust discharge port. When drilling, the cover 9 is closed, and the sucked-in dust is stored in the dust suction chamber 7. After drilling is completed, the cover 9 is opened, and the dust is discharged from the bottom side of the drilling rig body 1 through the dust discharge port under its own weight.

[0035] One side of the cover 9 is rotatably connected to the dust outlet side of the drill body 1 via a hinge. The other side of the cover 9 is a free side and can rotate relative to the drill body 1 around the hinge. A locking assembly is provided between the free side of the cover 9 and the other side of the dust outlet of the drill body 1. The locking assembly is used to lock the cover 9 with the dust outlet when it is closed.

[0036] The locking assembly includes a slot 10 and a tongue 11. The slot 10 is located on the outside of the dust outlet of the drill body 1, and the tongue 11 is located on the free side of the cover 9. When the cover 9 is closed, the tongue 11 on the cover 9 is inserted into the slot 10 at the dust outlet of the drill body 1 to complete the locking.

[0037] The main body 1 of the drilling rig is provided with a dust inlet 12, which is connected to the dust suction chamber 7. A dust suction pipe 13 is connected to the dust inlet 12, and the end of the dust suction pipe 13 is connected to the dust collection hood 3 so that the dust in the dust collection hood 3 can be sucked into the dust suction chamber 7 through the dust suction pipe 13.

[0038] The dust collection hood 3 is a cylindrical elastic cover structure. The dust collection hood 3 has a dust suction port on its wall, which is connected to the end of the dust suction pipe 13. One axial end of the dust collection hood 3 is open, and the other axial end of the dust collection hood 3 forms a sealing plate 14. The sealing plate 14 is provided with a snap-fit. The dust collection hood 3 is snapped into the drilling end of the drill body 1 through the snap-fit, and the drill bit clamp 2 passes through the snap-fit ​​and is fitted into the dust collection hood 3. The drill body 1 is provided with an annular groove 15 at the drilling end. When drilling, the open end of the dust collection hood 3 is attached to the wall. As the drilling depth of the drill bit gradually increases, the distance between the drill body 1 and the wall gradually decreases, and the dust collection hood 3 is also gradually compressed and deformed axially. After drilling is completed, as the drill bit gradually withdraws from the hole, the distance between the drill body 1 and the wall gradually increases, and the dust collection hood 3 is also axially extended and returns to its original shape.

[0039] It should be noted that the inner diameter of the dust collection hood 3 should be larger than the diameter of the drill bit chuck 2 to avoid the drill bit chuck 2 from contacting the inner wall of the dust collection hood 3 and to prevent the dust collection hood 3 from being worn when the drill bit chuck 2 rotates; moreover, the axial length of the dust collection hood 3 should be greater than the length of the drill bit after clamping, so that the dust collection hood 3 can fit against the wall before drilling to form a sealed dust collection chamber, ensuring that the dust generated during the drilling process is concentrated in the dust collection hood 3.

[0040] The drill chuck 2 is a drill chuck in the prior art. The drill chuck 2 has a connecting part 201 and movable clamping parts 202 disposed on the connecting part 201. At least three clamping parts 202 are provided. The clamping parts 202 are arranged at equal intervals around the center of the connecting part 201, and a clamping cavity is formed between the clamping parts 202. After the drill bit is inserted into the clamping cavity, the clamping parts 202 are driven to move closer to the center of the connecting part 201 to fix the drill chuck 2 tightly. The drill bit and the drill chuck 2 are coaxial after clamping. The connecting part 201 of the drill chuck 2 is connected to the power output end of the power member extending from the drilling end of the drill body 1 on the side opposite to the clamping parts 202, so as to receive the power provided by the power member and rotate around the axis.

[0041] The power component is a dual-head brushless motor 16, which has a first output shaft 16a and a second output shaft 16b. The first output shaft 16a extends axially from the drilling end of the drill body 1 and is connected to the drill bit chuck 2. The second output shaft 16b is connected to the dust collection mechanism through a transmission assembly. When the dual-head brushless motor 16 is started, the first output shaft 16a and the second output shaft 16b rotate simultaneously, thereby simultaneously driving the drill bit chuck 2 and the dust collection mechanism. Moreover, since the dual-head brushless motor 16 is used as the power component, there is no need to add an additional drive device to drive the dust collection mechanism, which effectively reduces the overall size and weight of the drill, making it easy to carry and operate by hand.

[0042] The dust collection mechanism includes a first filter element with one side opposite to the dust inlet 12 on the drill body 1, a second filter element disposed above the first filter element, and a negative pressure element disposed on one side of the second filter element; the negative pressure element is connected to the second output shaft 16b of the dual-head brushless motor 16 via a transmission assembly, and the drill body 1 is provided with an exhaust port 17 communicating with the power chamber 6; when the second output shaft 16b of the dual-head brushless motor 16 drives the negative pressure element through the transmission assembly, the negative pressure element can form an airflow in the drill body 1 that passes sequentially through the dust inlet 12, the dust collection chamber 7, the first filter element, the second filter element, the transmission channel 8, the power chamber 6, and the exhaust port 17.

[0043] A first dust collection space is formed between the first filter element and the inner wall of the dust collection chamber 7, and a second dust collection space is formed inside the first filter element. The second filter element is attached to the inner wall of the dust collection chamber 7. A partition 18 is provided on the top of the first filter element. The partition 18 is used to close the top opening of the first dust collection space to isolate the first dust collection space from the second filter element. The second dust collection space is connected to the second filter element, so that the airflow can pass through the first dust collection space, the second dust collection space and the second filter element in sequence.

[0044] The first filter element includes a cylindrical first support 19, a first filter screen 21 covering the periphery of the first support 19, and a baffle 20 sealing the bottom of the first support 19. The top of the first support 19 forms an opening and communicates with the second filter element. The outer diameter of the first support 19 is smaller than the inner diameter of the dust collection chamber 7 to form an annular first dust collection space. The baffle 20 is correspondingly set as an annular plate. Since the baffle 20 can prevent airflow from the bottom of the first support 19, while the first filter screen 21 can allow airflow from the periphery of the first support 19, the airflow entering the first dust collection space flows in a spiral shape, so that dust is sucked in from the dust inlet 12. Large dust particles are blocked by the first filter screen 21 and spiral upward in the first dust collection space. Small dust particles pass through the first filter screen 21 and enter the second dust collection space. The baffle 20 prevents large dust particles from rising into the second filter element and falling back to the bottom of the dust collection chamber 7.

[0045] The second filter element includes a cylindrical second support 22 and a second filter screen 23 disposed at the bottom of the second support 22. The mesh density of the second filter screen 23 is greater than that of the first filter screen 21. The bottom end of the second support 22 is connected to the top opening of the first support 19, and the top end of the second support 22 is closed. One circumferential side of the second support 22 is in contact with the inner wall of the dust collection chamber 7, and the other circumferential side of the second support 22 is provided with a vent hole 24. The suction end of the negative pressure component is opposite to the vent hole 24. Since the second filter screen 23 can allow airflow from the bottom of the second support 22, the airflow inside the second dust collection space can flow upward axially. Small dust particles are blocked by the second filter screen 23 in the second dust collection space. The filtered gas is extracted through the vent hole 24 on the second support 22, flows through the transmission channel 8, and is discharged from the exhaust port 17 on the drill body 1.

[0046] In this embodiment, a negative pressure airflow is generated by setting a negative pressure component, and the inhaled dust is collected twice by two filters to prevent dust from leaking to the outside of the drilling rig body 1 and polluting the air, thus ensuring the dust collection effect.

[0047] The negative pressure component includes a rotating shaft 25 rotatably mounted in the dust collection chamber 7 via a bearing bracket. The rotating shaft 25 is opposite to the vent 24 on the second bracket 22, and the axis of the rotating shaft 25 is perpendicular to the axis of the second bracket 22. The end of the rotating shaft 25 near the vent 24 is the suction end and is equipped with an impeller 26. The other end of the rotating shaft 25 is the exhaust end and is connected to the second output shaft 16b of the dual-head brushless motor 16 via a transmission assembly. The dual-head brushless motor 16 drives the rotation of the rotating shaft 25 through the transmission assembly, which in turn drives the impeller 26 to rotate accordingly, thereby forming a negative pressure airflow in the drill body 1. The airflow filtered by the second filter 23 enters the power chamber 6 from the dust collection chamber 7 through the transmission channel 8 and is discharged through the exhaust port 17 on the drill body 1, thereby dissipating the heat generated by the dual-head brushless motor 16 in the power chamber 6 and achieving cooling and heat dissipation.

[0048] The transmission assembly includes a drive gear 27 and a driven gear 28. The drive gear 27 is mounted on the second output shaft 16b of the dual-head brushless motor 16, and the driven gear 28 is mounted on the air outlet end of the rotating shaft 25. The drive gear 27 and the driven gear 28 mesh with each other to transmit the power generated by the dual-head brushless motor 16 to the rotating shaft 25.

[0049] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
