DETAILED DESCRIPTION

[0021] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The utility model provides a technical solution: Figure 1-5 The utility model discloses a pruning device for forestry planting, including a cutter 1, a casing 2 is slidingly sleeved on the outer peripheral side of the cutter 1, and the blade of the cutter 1 extends outside the casing 2, an L-shaped pad 3 is fixedly mounted on the open end of the casing 2, a smearing mechanism 5 is commonly provided in the casing 2 and the cutter 1, and a driving mechanism 4 is commonly provided in the cutter 1 and at the rear end of the casing 2.

[0023] In this embodiment, when the modified branch cutting device is used, the operator holds the outer shell 2 to erect the pad 3 upwards, and moves the device so that the branch is inserted into the pad 3. Then the operator starts the driving mechanism 4, and the driving mechanism 4 pushes the cutter 1 in the direction of the pad 3. Due to the constraint and limitation of the pad 3 on the branch, the blade of the cutter 1 is gradually inserted into the branch until the blade of the cutter 1 is connected to the pad 3. At this time, the cutter 1 cuts off the branch, and then the operator presses the cutter 1 in the direction of the branch break to apply the healing agent to the branch break through the applying mechanism 5.

[0024] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the driving mechanism 4 includes a circular tube 42 with a T-shaped cross section, a plurality of circular grooves 41 are provided on the right side of the cutter 1, the circular tube 42 is slidably mounted in the circular grooves 41, a rectangular shell 43 is fixedly mounted on the rear side of the housing 2, and one end of the circular tube 42 close to the rectangular shell 43 is inserted into the rectangular shell 43 and fixedly connected to the shell wall of the housing 2;

[0025] In this embodiment, during the movement of the cutter 1, due to the mutual interference between the circular tube 42 and the inner wall of the circular groove 41, the cutter 1 acts as a linear track, so that the cutter 1 will not produce an angle deviation during the movement;

[0026] It should be noted that a sealing ring is installed on the outer peripheral wall of the circular tube 42 to seal the gap between the circular tube 42 and the inner wall of the corresponding circular groove 41 .

[0027] In a further preferred embodiment of the present invention, Figure 3 As shown, an air pump 44 is fixedly installed in the rectangular shell 43, and the air inlet end of the air pump 44 is fixedly penetrated through the shell wall of the rectangular shell 43, and a pressure limiting valve 45 is provided on the top side of the rectangular shell 43, and the pressure limiting valve 45 is fixedly penetrated through the shell wall of the rectangular shell 43;

[0028] In this embodiment, after the branch is inserted into the pad 3, the air pump 44 is started to continuously pump the outside air out of the rectangular shell 43, thereby increasing the air pressure in the rectangular shell 43. At the same time, part of the gas in the rectangular shell 43 flows into the circular groove 41 through the circular tube 42, thereby increasing the air pressure in the circular groove 41, thereby pushing the cutter 1 toward the pad 3. When the cutter 1 contacts the branch, since the cutter 1 cannot continue to move, the pressure in the circular groove 41 continues to rise, thereby increasing the resistance between the cutter 1 and the branch, so that the blade of the cutter 1 can smoothly insert into the branch to cut the branch;

[0029] When the pressure in the housing 2 reaches the set value, the pressure difference at both ends of the pressure limiting valve 45 reaches the threshold value at the same time, and then the excess air in the housing 2 flows out of the housing 2 through the pressure limiting valve 45, so that the cutter 1, the round rod and the housing 2 will not generate excessive resistance force to cause damage to the device;

[0030] It should be noted that, as mentioned above, a battery for powering the air pump is fixedly mounted in the rectangular shell by means of a buckle.

[0031] In a further preferred embodiment of the present invention, Figure 1 As shown, the smear mechanism 5 includes a waterproof bolt 51, which is arranged on the top side of the housing 2, and the bottom end of the waterproof bolt 51 extends to the inner wall of the housing 2 and is threadedly connected to the housing 2, and a sealing ring 52 is fixedly installed in the opening wall of the housing 2, and the inner ring wall of the sealing ring 52 contacts the outer peripheral wall of the cutter 1;

[0032] In this embodiment, when adding the healing agent into the outer shell 2, the operator rotates the outer shell 2 so that the waterproof bolt 51 faces upward, and then the operator unscrews the waterproof bolt 51 from the outer shell 2. A suitable amount of healing agent can be injected into the outer shell 2 through the hole on the top side of the outer shell 2, and then the waterproof bolt 51 is screwed back into the outer shell 2, and the sealing ring 52 seals the cutter 1 and the inner wall of the opening of the outer shell 2. The healing agent is stored in a closed space to prevent the healing agent from being in contact with the outside air for a long time, which may cause the healing agent to deteriorate and be damaged.

[0033] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, a rectangular groove 53 with a T-shaped cross section is provided at the rear side of the cutter 1, a first sponge board 54 is fixedly installed in the opening of the rectangular groove 53, and the rear side of the first sponge board 54 is coplanar with the rear side of the cutter 1;

[0034] In this embodiment, after the above-mentioned cutter 1 is moved out of the outer shell 2, the first sponge board 54 can be moved out of the outer shell 2 simultaneously. At this time, the operator moves the cutter 1 toward the direction of the branch break. Due to the mutual interference between the first sponge board 54 and the branch break, part of the first sponge board 54 shrinks and deforms, so that the branch break is inserted into the first sponge board 54, so that the healing agent in the first sponge board 54 adheres to the branch break, and the device operation is relatively simple.

[0035] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, a mesh plate 55 is provided on the front side of the first sponge plate 54, and the outer peripheral wall of the mesh plate 55 is fixedly connected to the inner wall of the rectangular groove 53;

[0036] In this embodiment, the above-mentioned branch fractures conflict with the first sponge board 54. During the process of the first sponge board 54 being damaged and deformed, due to the obstruction of the branches, almost all of the healing agent squeezed out of the first sponge board 54 passes through the holes of the mesh plate 55 and flows into the rectangular groove 53 for storage, so that the healing agent squeezed out of the first sponge board 54 will hardly flow to the outside and cause unnecessary loss of the healing agent.

[0037] In a further preferred embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, the outer peripheral side sliding sleeve of the cutter 1 is provided with a second sponge plate 56, and the outer wall of the second sponge plate 56 is fixedly connected to the inner wall of the housing 2, and the inner wall of the second sponge plate 56 is connected to the rear side of the first sponge plate 54;

[0038] In this embodiment, after the first sponge plate 54 is retracted into the outer shell 2 , if the healing agent in the outer shell 2 is too little, the first sponge plate 54 can absorb the healing agent at the bottom of the outer shell 2 through the second sponge plate 56 .

[0039] Working principle: When the improved pruning device is used, the operator holds the outer shell 2 and erects the pad 3 upward, and moves the device so that the branches are stuffed into the pad 3, and then starts the air pump 44 to continuously extract the outside air from the rectangular shell 43, thereby increasing the air pressure in the rectangular shell 43. At the same time, part of the gas in the rectangular shell 43 flows into the circular groove 41 through the circular tube 42, so that the air pressure in the circular groove 41 is synchronously increased, thereby pushing the cutter 1 toward the pad 3. When the cutter 1 contacts the branch, since the cutter 1 cannot continue to move, the pressure in the circular groove 41 continues to rise, thereby increasing the resistance between the cutter 1 and the branch. At the same time, due to the constraint and limitation of the pad 3 on the branch, the blade of the cutter 1 is inserted into the branch until the blade of the cutter 1 is connected with the pad 3. At this time, the blade of the cutter 1 penetrates the branch and cuts off the branch;

[0040] It should be noted that when the pressure in the housing 2 reaches the set value, the pressure difference at both ends of the pressure limiting valve 45 reaches the threshold value at the same time, and then the excess air in the housing 2 passes through the pressure limiting valve 45 and flows out of the housing 2, and the cutter 1 will not receive excessive thrust;

[0041] When the above-mentioned cutter 1 completes the shearing of the branch, the movement of the cutter 1 synchronously pulls the first sponge board 54 out of the shell 2. After the cutter 1 completes the shearing of the branch, the operator continues to move the device upward so that the branch fracture moves to the position of the first sponge board 54, and then moves the cutter 1 in the direction of the branch fracture. Due to the mutual interference between the first sponge board 54 and the branch fracture, part of the first sponge board 54 shrinks and deforms, so that the branch fracture is inserted into the first sponge board 54, so that the healing agent in the first sponge board 54 adheres to the branch fracture, and then the air pump 44 extracts the gas in the rectangular shell 43 and the circular groove 41. At this time, as the gas in the circular groove 41 continues to lose, a relatively stable negative pressure chamber is formed in the circular groove 41, so that the cutter 1 is pulled back into the shell 2 for storage, and after the cutter 1 is retracted into the shell 2, the first sponge board 54 contacts the healing agent again, and the first sponge board 54 is re-infiltrated;

[0042] It should be noted that, as the gas in the rectangular shell 43 and the circular groove 41 is lost, the rectangular shell 43 presents a negative pressure chamber. After the pressure difference at both ends of the pressure limiting valve 45 reaches a threshold value, the external gas flows into the rectangular shell 43 through the pressure limiting valve 45. The operator can judge whether the cutter 1 has completed the retraction and reset or the branch pruning operation according to the sound generated by the gas flow at the pressure limiting valve 45;

[0043] The branch fractures and the first sponge plate 54 are in conflict with each other. During the process of the first sponge plate 54 being damaged and deformed, due to the obstruction of the branches, almost all of the healing agent squeezed out of the first sponge plate 54 passes through the holes of the mesh plate 55 and flows into the rectangular groove 53 for storage, so that the healing agent squeezed out of the first sponge plate 54 will hardly flow to the outside and cause unnecessary loss of the healing agent.

[0044] After the first sponge plate 54 is retracted into the housing 2, if the healing agent in the housing 2 is too little, the first sponge plate 54 can absorb the healing agent at the bottom of the housing 2 through the second sponge plate 56;

[0045] When adding the healing agent into the shell 2, the operator rotates the shell 2 so that the waterproof bolt 51 faces upward, and then the operator unscrews the waterproof bolt 51 from the shell 2, and injects a proper amount of the healing agent into the shell 2 through the hole on the top side of the shell 2, and then screws the waterproof bolt 51 back into the shell 2, cooperates with the sealing ring 52 to seal the cutter 1 and the inner wall of the opening of the shell 2, and the healing agent is stored in the closed space.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
