Description

Technical Field

[0001] The utility model relates to an ash collecting device, in particular to an improved electric hammer ash collecting device. Background Art

[0002] The use of electric drills to drill holes will generate a lot of dust and slag, which will pollute the environment. The dust floating in the air will also cause great harm to the health of the operators. For this reason, there are ash collecting bowls on the market for collecting dust and slag during drilling. The specific structure is as follows: Figure 1 As shown. When in use, the drill bit is passed through the ash receiving bowl. During the drilling process, the ash receiving bowl is covered on the wall to be drilled. The dust and slag generated during drilling are collected in the ash receiving bowl, which effectively prevents the dust from spreading during the drilling process. However, during use, the applicant found that the existing ash receiving bowl still has a big problem, that is, the dust and slag generated by drilling will gather at the bottom of the ash receiving bowl, and the vibration generated during the drilling process makes it easy for dust to enter the machine from the drill bit of the electric drill. If a large amount of dust enters, it will block the impact rod inside the machine, causing the machine to have no impact. Utility Model Content

[0003] In order to solve the above-mentioned problem, the present application provides an improved dust collecting device for an electric hammer, which can guide the collected dust to the periphery of the dust collecting bowl base to prevent the dust from entering the interior of the electric drill and affecting the normal use of the electric drill.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0023] Example

[0024] like Figure 2 As shown, the present embodiment discloses an improved ash receiving device for an electric hammer, which includes an ash receiving base 2, an ash guide cover 3 and a telescopic ash receiving cylinder 1. The ash guide cover 3 is conical, and is arranged inside the ash receiving base 2, and an ash storage bin 8 is formed between the ash guide cover 3 and the surrounding inner walls of the ash receiving base 2. The telescopic ash receiving cylinder 1 is connected to the ash receiving base 2 and is connected to the ash storage bin 8. A drill hole 6 for a drill bit to pass through is provided at the center of the ash guide cover 3, and a bayonet is provided at the lower end of the ash receiving base 2. When in use, the entire device can be installed on the drill bit changing sleeve of the electric hammer head through the bayonet, and the drill bit of the electric hammer passes through the drill hole 6 and extends into the telescopic ash receiving cylinder 1.

[0025] The length of the telescopic ash receiving cylinder 1 can be extended and retracted. In the initial state, the drill bit is stored inside the telescopic ash receiving cylinder 1. When drilling, the front end of the telescopic ash receiving cylinder 1 is covered on the wall to be drilled. When the electric hammer is pushed forward, the telescopic ash receiving cylinder 1 contracts, so that the drill bit of the electric hammer touches the wall. At this time, the drilling operation can be started, and the dust and slag generated during the drilling are collected in the device. In this embodiment, the ash guide cover 3 is designed in a conical shape. Therefore, when the collected dust and slag fall along the telescopic ash receiving cylinder 1 to the ash receiving base 2, the conical ash guide cover 3 can well guide the dust and slag to the ash storage bin 8 around it, reducing the probability of dust entering the machine from the drill mouth of the electric hammer, thereby ensuring the working performance of the machine.

[0026] The telescopic ash receiving cylinder 1 is a telescopic cylindrical structure, such as a bellows; or the telescopic ash receiving cylinder 1 is a telescopic structure composed of an inner cylinder and an outer cylinder, the outer cylinder is sleeved outside the inner cylinder, and the outer cylinder can move forward and backward to achieve a telescopic function.

[0027] In addition, as another implementation of this embodiment, the telescopic ash receiving cylinder 1 and the ash receiving base 2 are detachably connected, for example, the telescopic ash receiving cylinder 1 and the ash receiving base 2 can be connected by a buckle or by a thread. The telescopic ash receiving cylinder 1 and the ash receiving base 2 can be detached, so that the telescopic ash receiving cylinder 1 can be easily replaced and cleaned.

[0028] As another implementation of this embodiment, an ash discharge port 4 connected to the ash storage bin 8 is provided on the side wall of the ash receiving base 2. When in use, the ash discharge port 4 can be connected to an external suction device, and the ash can be continuously discharged during the drilling process through the suction device, avoiding the need to repeatedly pour ash during the drilling process and affecting the work efficiency. Of course, when in use, it is also possible not to connect an external suction device, and only need to connect an ash discharge pipe to the ash discharge port 4, and the dust in the ash storage bin 8 can also be discharged through the ash discharge pipe.

[0029] In addition, an ash discharge port plug 5 is provided on the ash discharge port 4. When a small amount of work is performed, the ash discharge port plug 5 can be used to block the ash discharge port 4, and the ash can be dumped at one time after the drilling is completed, which is more convenient to use.

[0030] As another implementation of this embodiment, a bushing 7 is embedded in the drill hole 6, and there is an interference fit between the bushing 7 and the drill hole 6. The bushing 7 can be made of wear-resistant metal materials, such as iron or steel. The bushing 7 can prevent the ash guide cover 3 from being worn when the drill rotates, effectively improving the service life of the device.
