[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 , the utility model provides a technical solution:

[0018] In the technical solution, a forestry tree peeling device includes a support device 100 and a peeling device 200, the two support devices 100 are symmetrically distributed and fixed on the ground, the support device 100 includes a support frame 110 and a limit frame 120, the bottom of the support frame 110 is fixed to the ground by bolts, the limit frame 120 is welded to the top of the support frame 110, and the inner side wall of the limit frame 120 is an arc surface;

[0019] In this technical solution, the support frame 110 and the limiting frame 120 cooperate with each other to support the tree to be peeled, so that the tree is horizontally placed in the chamber formed by the two limiting frames 120.

[0020] The peeling device 200 is located below the middle of the two supporting devices 100. The peeling device 200 includes a guide plate 210, a chain 220, a first electric push rod 230, a skin cutter 240 and a mounting plate 250. The two guide plates 210 are symmetrically distributed and fixed to the ground through a stand. One end of the stand is welded to the outer wall of the guide plate 210, and the other end is fixed to the ground by bolts. A moving block 211 is slidably connected to the middle of the two guide plates 210. The chain 220 is fixed to the ground through a mounting frame. The bottoms of the two mounting frames are respectively fixed to the ground by bolts. The chain 220 is sleeved on the outside of the two mounting frames. The inside of the mounting frame is rotatably connected to a driving wheel 222 through a rotating shaft. The mounting frame The outer wall of the mounting frame is fixed with a second motor 221, the outer wall of the mounting frame is welded with a support rod, the second motor 221 is fixed to the support rod by bolts, the chain 220 passes through the moving block 211 and is fixedly connected, the first electric push rod 230 is fixed to the top of the moving block 211 by bolts, the skin cutter 240 is fixed to the moving end of the first electric push rod 230, the mounting plate 250 is connected to the outer wall of the guide plate 210 by a connecting rod 212, the connecting rod 212 is an L-shaped structure, and the two ends of the connecting rod 212 are respectively welded to the mounting plate 250 and the guide plate 210, the surface of the mounting plate 250 is fixed with a second electric push rod 251, and the moving end of the second electric push rod 251 is fixedly connected with a peeling rod 252;

[0021] In this technical solution, the second motor 221 and the driving wheel 222 cooperate with each other to drive the chain 220 to rotate. When the chain 220 rotates, it drives the moving block 211 to move. The moving block 211 is blocked by the two guide plates 210 and performs linear reciprocating motion. The first electric push rod 230 is used to control the movement of the barker 240 in the vertical direction, so that the barker 240 contacts and separates from the tree. When the barker 240 contacts the tree, the bark at the bottom of the tree can be cut to cut an opening. The mounting plate 250 and the connecting rod 212 are used to provide mounting points for the installation of the second electric push rod 251. The second electric push rod 251 is used to control the movement of the stripping rod 252, so that the end of the stripping rod 252 contacts or separates from the tree. The stripping rod 252 is used to be stuck in the middle of the bark and the wood.

[0022] In some technical solutions, reference Figure 1-2 The barker 240 includes a transverse plate 241, a cutting knife 242 and a separating plate 243. The two cutting knives 242 are welded to the top of the transverse plate 241, and the separating plate 243 is welded to the top of the two cutting knives 242. The cut surfaces of the cutting knives 242 and the separating plate 243 are in contact with the bark.

[0023] In this technical solution, when the two cutting knives 242 come into contact with the bark, the bark is cut using the cutting surface, leaving a strip of bark in the middle of the cutting by the two cutting knives 242. The strip of bark can be separated from the wood under the action of the separation plate 243 to complete the peeling of the strip of bark.

[0024] In some technical solutions, reference Figure 1 and Figure 3 A first motor 130 is fixed to the outer wall of the right support frame 110 by bolts, and a belt 131 is wound around the driving end of the first motor 130. The interior of the limit frame 120 is rotatably connected to multiple rotating columns 121 through bearings. A driving cylinder 123 is clamped on the outside of one of the rotating columns 121, and a protrusion extends from the outer wall of the driving cylinder 123. The outside of another rotating column 121 is rotatably connected to a rotating cylinder 122.

[0025] In this technical solution, the first motor 130 and the belt 131 are used to drive a rotating column 121 to rotate, and the rotating column 121 drives the driving cylinder 123 to rotate. The tree can rotate stably and synchronously due to the friction of the protrusions, and the use of the rotating cylinder 122 can reduce the friction between the tree and the limit frame 120 when rotating.

[0026] In some technical solutions, reference Figure 1-2 A guide groove is formed inside the guide plate 210 , and the moving block 211 slides along the guide groove. The outer wall of the moving block 211 is inlaid with a ball 213 , and the ball 213 is in rolling contact with the inner wall of the guide groove.

[0027] In this technical solution, the ball 213 utilizes rolling contact instead of the sliding contact between the moving block 211 and the guide plate 210 , which can reduce the resistance encountered by the moving block 211 when moving in the guide plate 210 .

[0028] In some technical solutions, reference Figure 1 A wedge-shaped block is extended from the end of the peeling rod 252, and the inclined surface of the wedge-shaped block is stuck in the middle of the bark and the wood.

[0029] In this technical solution, the cut surface of the wedge block can be effectively inserted into the middle of the bark and the wood, and the side of the bark opening can be easily pried open to complete the separation between the bark and the wood.

[0030] Working principle: First, connect the first motor 130, the second motor 221, the second electric push rod 251, and the first electric push rod 230 to the external control device and power supply, and then place the tree to be peeled horizontally in the chamber composed of two limit frames 120. At this time, the external pressing mechanism (the pressing mechanism is composed of the third electric push rod and the pressing block) presses the tree. At this time, the control switch of the second motor 221 and the first electric push rod 230 is operated, so that the second motor 221 drives the driving wheel 222 to The chain 220 rotates, and the first electric push rod 230 pushes the bark cutter 240 to rise, so that the cutting knife 242 and the separation plate 243 are aligned with the bark, and the chain 220 drives the moving block 211 to make a linear motion. At this time, the first electric push rod 230 and the bark cutter 240 move synchronously with the moving block 211, and the cutting knife 242 cuts the bark, and the separation plate 243 separates the cut strips of bark until it moves from one end of the tree to the other end. At this time, the bark cutter 240 completes the outer bark of the tree. The first electric push rod 230 drives the barker 240 to descend, and the second motor 221 rotates in the opposite direction, so that the moving block 211 moves back to reset, and the pressing mechanism moves up slightly at this time, leaving a gap between the tree and the push rod 251; at this time, the control switch of the second electric push rod 251 and the first motor 130 is operated, and the second electric push rod 251 pushes the debarking rod 252 to move obliquely upward until it contacts the bottom of the tree. At this time, the first motor 130 drives the rotating column 121 connected thereto to rotate through the belt 131, and the rotating column 121 drives the driving cylinder 123 to rotate, and the driving cylinder 123 drives the tree to rotate counterclockwise. While the tree is rotating, the wedge block on the debarking rod 252 is stuck between the bark and the wood. As the tree rotates, the bark can be stably separated from the wood, and the fallen bark is led out along the gap between the debarking rod 252 and the bottom of the left limit frame 120. After the tree rotates one circle, the debarking of the tree is completed, and the debarked wood is left in the chamber formed by the two limit frames 120.
