[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] When in use, the branches are cut with an electric saw. After the branches are cut, the broken branches enter the cover plate. At this time, the cut end is aligned with the brush. Move the pruning device so that the cut end comes into contact with the brush bristles. The pump body pumps the protective agent inside the protective agent box into the water pipe. The protective agent is delivered to the surface of the brush through the water pipe. The brush is driven by a motor to rotate, applying the protective agent to the cut end. This allows the protective agent to be applied to the surface of the broken branch after pruning, preventing the cut end from being exposed and causing bacterial infection and accelerated moisture loss.

[0021] This utility model provides the following technical solution:

[0022] Combination Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a forestry tree branch pruning device, including an electric saw 1, which is mounted on a fixed plate 2. A cover plate 3 is mounted above the electric saw 1. The cover plate 3 has a herringbone cross-section. The outer side of one end of the cover plate 3 is fixedly connected to the fixed plate 2 via a connecting rod 4. A vertical plate 5 is fixedly connected to one side of the cover plate 3. A brush 6 is rotatably mounted on the vertical plate 5 at the top of the inner side of the cover plate 3. The brush 6 is connected to a motor 7. A protective agent box 8 is mounted on the fixed plate 2. The protective agent box 8 is connected to the water inlet of a pump body 9. The water outlet of the pump body 9 is connected to one end of a water pipe 10. The other end of the water pipe 10 extends to the surface of the brush 6.

[0023] In use, the branches are cut with the electric saw 1 to achieve the purpose of pruning. After the electric saw 1 cuts the branches, the broken branches enter the inside of the cover plate 3. Since the cross-section of the cover plate 3 is a herringbone structure, the broken branches fall into the top of the inside of the cover plate 3. At this time, the cut end is aligned with the brush 6. Move the pruning device so that the cut end comes into contact with the bristles of the brush 6. The protective agent inside the protective agent box 8 is pumped into the water pipe 10 through the pump body 9. The protective agent is delivered to the surface of the brush 6 through the water pipe 10. The brush 6 is driven to rotate by the motor 7 to apply the protective agent to the cut end. After pruning, the surface of the broken branch can be coated with protective agent to avoid the problem of bacterial infection and accelerated moisture loss caused by the exposed cut end.

[0024] Specifically, in combination Figure 3 and Figure 4As shown, a cavity 11 for accommodating the brush 6 is provided on the upright plate 5 at the top inner side of the cover plate 3. The brush 6 is rotatably disposed in the cavity 11. A through hole 12 for the broken branch to enter is provided on the upright plate 5 corresponding to the bristles of the brush 6.

[0025] After the broken branch enters the cover plate 3, the inclined surface of the cover plate 3 guides the broken branch, causing it to move to the top of the inner side of the cover plate 3, thus positioning the broken branch with the through hole 12. The trimming device is moved, and after the broken branch passes through the through hole 12, the broken end contacts the bristles of the brush 6.

[0026] Specifically, in combination Figure 5 As shown, a liquid distribution box 13 is provided inside the cavity 11. The liquid distribution box 13 is arranged radially along the brush 6. The liquid distribution box 13 is connected to the water pipe 10, and the side of the liquid distribution box 13 opposite to the bristles of the brush 6 is provided at the liquid outlet 14.

[0027] The protective liquid is dispersed by the separator 13 and evenly applied to the brush 6 when the brush 6 rotates, so that the protective liquid can be evenly applied to the fracture surface when the brush 6 rotates.

[0028] Specifically, in combination Figure 2 As shown, the fixing plate 2 is fixedly connected to the front end of the grip 15.

[0029] The handle 15 facilitates hand-held pruning of lower branches.

[0030] Specifically, in combination Figure 2 As shown, the rear end of the grip 15 is coaxially threaded with an extension rod 16.

[0031] The extension rod 16 extends the length of the handle 15, making it easier to hold the pruning device and prune branches at higher positions.
