Description

Technical Field

[0001] This application relates to the field of garden tool technology, and in particular to a high-branch chainsaw. Background Technology

[0002] A high-branch chainsaw is a type of garden tool primarily used for pruning tall trees. The structure of a high-branch chainsaw mainly includes a body assembly, a support rod, and a handle. The body assembly consists of a housing and a chainsaw blade, which rotates within one end of the housing. When the high-branch chainsaw is in operation, the chainsaw blade produces sawdust as it cuts the tree. As the chainsaw continues to work, it draws the sawdust into the housing, where a structure drives the chainsaw blade. Subsequently, the sawdust becomes stuck in this structure, affecting the operation of the body assembly. Utility Model Content

[0003] The purpose of this utility model is to provide a high-branch chainsaw that addresses the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a housing and a chainsaw blade. One end of the chainsaw blade is wound inside the housing. The side wall of the housing has a discharge pipe. The inner end of the discharge pipe corresponds to a part of the chainsaw blade. The outer end of the discharge pipe is provided with a mounting frame, and a collection net bag is placed inside the mounting frame.

[0006] Preferably, the mounting frame includes a base plate and four support rods. One end of each of the four support rods is evenly disposed on the periphery of the base plate. Four mounting slots are evenly distributed on the inner circumferential side of one end of the unloading pipe. The other end of each support rod is inserted and fixed into the mounting slot.

[0007] Preferably, a first brush head is provided on the inner side of the unloading pipe, and the inner end of the first brush head is in contact with the chainsaw blade.

[0008] Preferably, a second brush head is provided on the inner side of the unloading pipe, and the inner end of the second brush head is in contact with the chainsaw blade.

[0009] Preferably, the outer ends of the first brush head and the second brush head are respectively snapped into two corresponding mounting slots.

[0010] Preferably, a buckle is provided on the inner side of the support rod, and the collection net bag is fastened and fixed to the buckle.

[0011] Preferably, a fan is provided at the outer end of the mounting bracket.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When the high branch chainsaw is working, the chainsaw blade will bring the wood chips into the housing. When the wood chips on the chainsaw blade are in the unloading pipe, they will fall into the collection net bag along the unloading pipe. This can prevent too many wood chips from entering the housing parts and affecting the operation of the high branch chainsaw, thus improving the service life of the high branch chainsaw.

[0014] 2. When the chainsaw blade is rotating, the first brush head sweeps the wood chips attached to the chainsaw blade off and they fall into the unloading pipe. The second brush head blocks the wood chips on the chainsaw blade from entering the housing, thereby further reducing the impact of wood chips on the high-branch chainsaw.

[0015] 3. The fan increases the airflow between the unloading pipe and the collection bag, which can attract the sawdust on the chainsaw blade and store the fine sawdust in the collection bag. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] This application discloses a high-branch chainsaw.

[0022] Reference Figure 1 It includes a chainsaw blade 1, a housing 2, a support rod 3, and a handle 4. The handle 4 is sleeved and fixed to one end of the support rod 3, and the housing 2 is rotatably connected to the other end of the support rod 3. One end of the chainsaw blade 1 is wrapped and rotated inside the housing 2.

[0023] Reference Figure 2 and Figure 3The housing 2 has a discharge hole on its side wall, which exposes a portion of the chainsaw blade 1 to the outside. A discharge pipe 5 is integrally formed on the outside of the discharge hole, and a mounting bracket 6 is placed at the outer end of the discharge pipe 5. A collection mesh bag 7 is placed inside the mounting bracket 6. The chainsaw blade 1 will bring sawdust into the housing 2. When the sawdust on the chainsaw blade 1 is located inside the discharge pipe 5, it will fall into the collection mesh bag 7 along the discharge pipe 5, thereby preventing excessive sawdust from entering the parts of the housing 2 and affecting the operation of the high-branch chainsaw.

[0024] The mounting frame 6 includes a base plate 8 and four support rods 9. One end of each of the four support rods 9 is uniformly and integrally set on the periphery of the base plate 8. The base plate 8 is grid-shaped. Four mounting slots 10 are uniformly opened on the inner periphery of the outer end of the unloading pipe 5. The other end of each support rod 9 is inserted and fixed in the mounting slot 10.

[0025] A locking block 11 is integrally provided on the outer side of the inner end of the support rod 9, and a locking hole 12 is provided on the side wall of the mounting groove 10 for the locking block 11 to be engaged and fixed. When the mounting bracket 6 needs to be installed on the unloading pipe 5, simply insert one end of each of the four support rods 9 into the four mounting grooves 10 until the locking block 11 is engaged and fixed in the locking hole 12.

[0026] A first brush head 13 and a second brush head 14 are evenly fitted onto the inner circumference of the unloading pipe 5. The bristles of the second brush head 14 are denser than those of the first brush head 13. The first brush head 13 is located on the side wall of the unloading pipe 5 near the opening of the housing 2, and the second brush head 14 is located on the side wall of the unloading pipe 5 away from the opening of the housing 2. The bristles of the first brush head 13 and the second brush head 14 respectively contact the chainsaw blade 1. Under the sweeping action of the first brush head 13, the wood chips attached to the chainsaw blade 1 can be swept off and then fall into the unloading pipe 5. The second brush head 14 can block the wood chips on the chainsaw blade 1 from entering the interior of the housing 2, thereby further reducing the impact of wood chips on the high-branch chainsaw.

[0027] The vertical cross-sections of the first brush head 13 and the second brush head 14 are both L-shaped. The first brush head 13 and the second brush head 14 are respectively embedded in the bottom of two corresponding mounting slots 10 at the end away from the chainsaw blade 1, and the two support rods 9 respectively abut against the outer end faces of the first brush head 13 and the second brush head 14.

[0028] The inner wall of the support rod 9 is fixed with buckles 15 by bolts, and the collection net bag 7 is fastened to the four buckles 15.

[0029] A stabilizing base 16 is integrally provided on the outer end of the base plate 8, and a fan 17 is embedded and fixed inside the stabilizing base 16. Under the action of the fan 17, the air flow in the unloading pipe 5 and the collecting net bag 7 is increased, which can attract the wood chips on the chainsaw blade 1 and store the fine wood chips in the collecting net bag 7.

[0030] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
