[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-6This utility model provides an embodiment of a dust suppression device for chainsaws, comprising a chainsaw body 1, a saw blade 101 fixedly connected to one side of the chainsaw body 1, a saw chain 102 rotatably connected to the saw blade 101, a dust collection hood 2 fixedly connected to the lower end of the chainsaw body 1, a barrier net 3 fixedly connected to one side of the suction port of the dust collection hood 2, a fixing frame 301 provided at the edge of the barrier net 3, a connecting pipe 201 provided in the middle of the other side of the dust collection hood 2, a telescopic hose 4 connected to one side of the connecting pipe 201, a dust collection device 6 provided on the other side of the telescopic hose 4, the barrier net 3 being fixedly connected to the fixing frame 301, and the barrier net 3 having a fixed edge... The fixing frame 301 is fitted onto the outside of the suction port of the dust hood 2. The front and rear ends of the fixing frame 301 are fixedly connected to the front and rear ends of the dust hood 2 by multiple screws 302. When the chainsaw body 1 is working, the dust hood 2 sucks in air to reduce dust. The baffle net 3 at the suction port of the dust hood 2 blocks the wood chips generated during work, preventing the wood chips from entering the interior of the dust hood 2 and then entering the dust collection device 6 through the telescopic hose 4, thus affecting the operation of the dust collection device 6. At the same time, the fixing frame 301 can be separated from the dust hood 2 by removing the screws 302, making it easy to remove the baffle net 3 for maintenance and replacement.

[0026] Please see Figure 3-6 The dust hood 2 is fixedly connected to the connecting pipe 201. A tightening ring 401 is fixedly connected to one end of the telescopic hose 4 adjacent to the connecting pipe 201. A tubular rotating connector 5 is rotatably connected to the other end of the telescopic hose 4 adjacent to the connecting pipe 201. The tightening ring 401 on the telescopic hose 4 is inserted into the tubular rotating connector 5, allowing the tubular rotating connector 5 to rotate on the telescopic hose 4. Simultaneously, the tightening ring 401 prevents the tubular rotating connector 5 from detaching from the telescopic hose 4. An internal thread 501 is fixedly provided on the inner end face of the tubular rotating connector 5, and an external thread 202 is fixedly provided on the outer side of the connecting pipe 201. A tightening ring 401 is located on one side of the telescopic hose 4. 01 is attached to one side of the connecting pipe 201. The tubular rotating connector 5 is fitted into the outside of the connecting pipe 201 and is fixed by the internal thread 501 and the external thread 202. After the tubular rotating connector 5 is connected to the connecting pipe 201, the tightening ring 401 on one side of the telescopic hose 4 is attached to the side of the connecting pipe 201 to realize the connection between the dust hood 2 and the telescopic hose 4. After rotating the tubular rotating connector 5 to disengage from the connecting pipe 201, the telescopic hose 4 can be separated from the dust hood 2. The other end of the telescopic hose 4 is connected to the dust collection device 6 by a clamp. The dust collection device 6 is connected to the dust collection hood 2 through the telescopic hose 4 to reduce dust when the chainsaw body 1 is working.

[0027] Working Principle: During operation, the operator starts the chainsaw body 1 for logging or timber processing, and simultaneously activates the dust collection device 6, which is paired with the chainsaw body 1. The dust collection device 6 is connected to the dust collection hood 2 via a flexible hose 4, which tightly covers the working area of ​​the chainsaw chain on the chainsaw body 1. As the chainsaw chain operates, cutting wood generates a large amount of sawdust and dust. The dust collection hood 2 generates suction through its air inlet, drawing the sawdust and dust into its interior. However, because a barrier net 3 is fixedly connected to one side of the air inlet of the dust collection hood 2, this barrier net 3 effectively prevents sawdust from entering the interior of the dust collection hood 2, allowing only dust and fine particles to pass through. These blocked sawdust accumulate on the outside of the barrier net 3, while dust and fine particles enter the connecting pipe 201 through the internal channels of the dust collection hood 2. The connecting pipe 201 then transports the dust to the dust collection device 6 via the flexible hose 4. The design of the telescopic hose 4 not only ensures a flexible connection between the vacuum cleaner 6 and the vacuum hood 2, but also allows the vacuum cleaner 6 to move within a certain range to adapt to different operational needs. The vacuum cleaner 6 is typically equipped with a filtration system to collect and filter the sucked-in dust, thereby maintaining a clean working environment. After the operation is completed, the operator can remove the screws 302 to separate the fixing frame 301 from the vacuum hood 2, facilitating the cleaning or replacement of the barrier net 3 to ensure the continuous and effective operation of the dust suppression device.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
