Description

Technical Field

[0001] The present invention relates to the technical field of logging devices, and specifically to a logging device dedicated to round bamboo. Background Art

[0002] Round bamboo, as a natural resource widely distributed, growing rapidly and having a wide range of uses everywhere, with its unique physical properties and aesthetic value, has become an indispensable raw material in many fields such as construction, furniture, papermaking, and handicrafts.

[0003] Currently, a strip logging device for bamboo forests is disclosed in the patent publication number "CN216722430U". When logging round bamboo, it can change the cutting length of the bamboo to meet the requirements of different scenarios. However, after specific use and comparison with the prior art, there are still the following defects:

[0004] When the device logs round bamboo, the electric saw needs to move horizontally to log the round bamboo. Therefore, when cutting the bamboo, the device needs to be pushed horizontally, increasing the complexity of the operation. Moreover, when logging round bamboo in an inclined state, the base of the round bamboo will be cut into a sharp shape, and these sharp bases are likely to pose a safety hazard when people walk.

[0005] Therefore, the present invention proposes a logging device dedicated to round bamboo to make up for and improve the deficiencies of the prior art. Summary of the Invention

When the connecting member rotates, the limiting rod can drive the electric saw to reciprocate when swinging in an arc through the connecting member. Thus, when cutting round bamboo, it is not necessary to push the entire device, and when the electric saw reciprocates, it can cover the surface of the entire round bamboo faster, thereby accelerating the cutting process. And when cutting inclined round bamboo, the electric push rod changes the cutting angle of the electric saw, making the base of the cut round bamboo smooth, avoiding potential safety hazards when people walk.

[0019] 2. When the rotating frame swings in the present invention, the pushing frame can drive the cut round bamboo to tilt to the right, enabling the operator to more easily predict and control the falling direction of the round bamboo. Thus, it can avoid accidental injuries caused by the random falling of the round bamboo to people. And when the round bamboo tilts to the right uniformly, the round bamboo can be arranged more neatly, and it is also convenient for subsequent collection.

[0020] 3. When the transmission frame rotates, it can drive the punching machine to move back and forth, enabling the punched holes in the harvested round bamboo, so that the perforated round bamboo can be conveniently connected into strings by ropes, making the transportation of round bamboo more compact and stable during water transportation, and reducing losses caused by the rolling or scattering of round bamboo.

[0021] 4. When the rotating frame rotates, it can make the sliding frame move downward and insert into the soil, thus providing a stable support point for the harvesting equipment to reduce shaking and deviation during the harvesting process. It can also make the cut of the round bamboo flat, improve the harvesting accuracy, and prevent the harvesting equipment from tipping over due to loss of balance when harvesting tall round bamboo, protecting the safety of operators.

[0038] Embodiments of the present invention

[0039] Refer to Figures 1 to 6As shown in the figure, a felling device dedicated to round bamboo includes a pushing cart 1. The upper surface of the pushing cart 1 is rotatably connected to a rotating frame 11. The pushing cart 1 is used to drive the rotating frame 11 to move simultaneously. The inner side of the rotating frame 11 is rotatably connected to a saw 12. The rotating frame 11 is used to drive the saw 12 to move simultaneously. The saw 12 is used to fell the round bamboo. The upper surface of the rotating frame 11 is fixedly connected to a support plate 13. The inner side of the support plate 13 is rotatably connected to a rotating member 14. A plurality of tapered grooves are annularly formed on the outer surface of the rotating member 14. The support plate 13 is used to limit the rotation of the rotating member 14 inside the support plate 13. The upper surface at the rear of the support plate 13 is fixedly connected to a servo motor 16. The output end of the servo motor 16 is fixedly connected to a rotating gear 15. The output shaft of the servo motor 16 is used to drive the rotating gear 15 to rotate.

The front ends of the return springs 172 are fixedly connected to the inner surface of the rotating member 14. The return springs 172 are used to drive the connecting member 17 to move in a reset manner. The upper surface at the rear of the support plate 13 is fixedly connected to an arc-shaped rack 18. The tooth blocks on the side of the arc-shaped rack 18 close to the connecting member 17 gradually increase from left to right. The outer surface of the pressing block 171 is in pressing fit with the outer surface of the arc-shaped rack 18. When the pressing block 171 rotates, it is used to be pressed by the front side of the arc-shaped rack 18 to cause the pressing block 171 to gradually slide forward. When the pressing block 171 gradually moves forward, it is used to drive the connecting member 17 to move simultaneously inside the rotating member 14. The bottom of the connecting member 17 is fixedly connected to the upper surface at the rear of the saw 12. The connecting member 17 is used to drive the saw 12 to move simultaneously. Thus, when felling the round bamboo, it is not necessary to push the entire device, and when the saw 12 fells the raw bamboo and gradually moves forward, it can make the saw 12 cover the surface of the entire round bamboo faster, accelerating the felling process. The right side of the pushing cart 1 is fixedly connected to an electric push rod 19. The output end of the electric push rod 19 is fixedly connected to a fixing member 110. The output end of the electric push rod 19 is used to drive the fixing member 110 to move up and down. The outer surface at the top of the fixing member 110 is rotatably connected to a slider 112. The fixing member 110 is used to drive the slider 112 to move simultaneously. The upper surface of the slider 112 is slidably connected to a connecting frame 111. The slider 112 is used to jack up the connecting frame 111. The left side of the connecting frame 111 is fixedly connected to the right side of the rotating frame 11. The connecting frame 111 is used to drive the rotating frame 11 to turn up simultaneously. Thus, the rotating frame 11 can drive the saw 12 to turn up, changing the felling angle of the saw 12, making the base of the felled round bamboo smooth, and avoiding potential safety hazards when people walk.

A connecting spring 22 is fixedly connected to the right side of the pushing frame 21, and the right end of the connecting spring 22 is fixedly connected to the inner side of the right end of the guiding frame 2. The connecting spring 22 is used to drive the pushing frame 21 to move back to its original position. A moving frame 23 is fixedly connected to the upper surface at the rear side of the pushing frame 21. The moving frame 23 is used to drive the pushing frame 21 to slide to the right. A supporting frame 25 is fixedly connected to the upper surface of a supporting plate 13. A rotating frame 24 is rotatably connected to the center at the top of the supporting frame 25. A rotating column 26 is fixedly connected to the bottom at the right end of the rotating frame 24. The rotating column 26 is used to drive the rotating frame 24 to rotate simultaneously. The outer surface of the left end of the rotating frame 24 is in pressing fit with the outer surface of the top of the moving frame 23. The rotating frame 24 is used to drive the moving frame 23 to move to the right. A fixing strip 27 is fixedly connected to the outer surface of the rotating column 26. The fixing strip 27 is used to drive the rotating column 26 to rotate simultaneously. The bottom of the fixing strip 27 is fixedly connected to the upper surface of a rotating member 14. The rotating member 14 is used to drive the fixing strip 27 to rotate simultaneously. When the rotating frame 24 swings, it can make the moving frame 23 drive the pushing frame 21 to slide to the right, so that the harvested round bamboo can only tilt to the right, enabling the operator to more easily predict and control the falling direction of the round bamboo, and avoiding accidental injuries caused by the random falling of the round bamboo to people.

[0041] Reference Figures 9 to 11As shown in the figure, a harvesting device dedicated to round bamboo. A transmission wheel 3 is fixedly connected to the outer surface of a rotating column 26. When the rotating column 26 rotates, it is used to drive the transmission wheel 3 to rotate simultaneously. The outer surface of the transmission wheel 3 is drivingly connected to a conveyor belt 31. When the transmission wheel 3 rotates, it is used to drive the conveyor belt 31 to transmit. The inner side of the front end of the conveyor belt 31 is drivingly connected to a rotating disk 32. When the conveyor belt 31 transmits, it is used to drive the rotating disk 32 to rotate simultaneously. The bottom of the rotating disk 32 is rotatably connected to a support member 34. The support member 34 is used to limit the rotation of the rotating disk 32 on the upper surface of the support member 34. The bottom of the support member 34 is fixedly connected to the upper surface of a rotating frame 11. The upper surface of the rotating disk 32 is fixedly connected to an extrusion column 321. When the rotating disk 32 rotates, it is used to drive the extrusion column 321 to rotate simultaneously.

The movable end of the telescopic member 35 is fixedly connected to a drilling machine 36. When the movable end of the telescopic member 35 moves, it is used to drive the drilling machine 36 to move simultaneously. When the drilling machine 36 moves back and forth, it is used to drill holes in the outer surface of the round bamboo, so that the perforated round bamboo can be conveniently connected in series by ropes, so that the round bamboo can be transported more compactly and stably during water transportation, reducing losses caused by the rolling or scattering of the round bamboo.

[0042] Reference Figure 12 and Figure 13 As shown in the figure, a harvesting device dedicated to round bamboo. A connecting rod 43 is fixedly connected to the rear side of the right end of a rotating frame 24. When the rotating frame 24 rotates, it is used to drive the connecting rod 43 to rotate simultaneously. The outer surface of the right end of the connecting rod 43 is slidably connected to a fixed frame 42. Both ends of the fixed frame 42 are inclined. The outer surface of the right end of the connecting rod 43 is in extrusion fit with the inclined shape inside the fixed frame 42. The connecting rod 43 is used to drive the fixed frame 42 to move up and down. The lower surface of the fixed frame 42 is fixedly connected to a sliding frame 41. The fixed frame 42 is used to drive the sliding frame 41 to move simultaneously. The bottoms of both ends of the sliding frame 41 are conical. The bottom of the sliding frame 41 is used to insert into the soil for fixation. The outer surfaces of the bottoms of both ends of the sliding frame 41 are slidably connected to support blocks 4. The inner sides of the support blocks 4 are fixedly connected to both sides of the rotating frame 11. The support blocks 4 are used to limit the downward sliding of the sliding frame 41 inside the support blocks 4. By moving the sliding frame 41 downward and inserting it into the soil, a stable support point can be provided for the harvesting equipment to reduce the shaking and deviation during the harvesting process, and the cut of the round bamboo can also be made flat to improve the harvesting accuracy.

[0043] The complete working principle and steps of the above embodiments are as follows:

[0044] Reference Figures 1 to 6 As shown, when the logging equipment is in the initial state, the rotary frame 11 is in a horizontal state, the electric saw 12 is in a left-leaning state, the servo motor 16 is in an off state, and the electric push rod 19 is in a contracted state;

[0045] When using this equipment to log round bamboo, first push the push cart 1 to the position where logging is required. At this time, the operator starts the electric saw 12 and the servo motor 16. When the output shaft of the servo motor 16 rotates, it will drive the rotary gear 15 to rotate at the same time. When the rotary gear 15 rotates, it will engage in the tapered groove opened on the outer surface of the rotating part 14 and drive the rotating part 14 to rotate. When the rotating part 14 rotates inside the support plate 13, it will drive the connecting part 17 to rotate at the same time. When the connecting part 17 rotates, it can drive the electric saw 12 to rotate at the same time. At this time, when the electric saw 12 rotates in an arc inside the rotary frame 11, it can log the round bamboo. Therefore, when the electric saw 12 logs the round bamboo, it is not necessary to push the entire equipment. Since the inner side of the rotating part 14 is slidably connected to the inner side of the bottom of the connecting part 17, as the connecting part 17 rotates, it will drive the extrusion block 171 to rotate at the same time. When the extrusion block 171 rotates, it will be extrusion-fitted with the tooth blocks on the side of the arc-shaped rack 18 close to the connecting part 17. Since the rack on the side of the arc-shaped rack 18 close to the connecting part 17 gradually increases from left to right, when the extrusion block 171 is extruded with the tooth blocks of the arc-shaped rack 18, it will cause the extrusion block 171 to gradually move to the left. When the extrusion block 171 gradually moves to the left, it will drive the connecting part 17 to move at the same time. When the connecting part 17 moves to the left inside the rotating part 14, it will cause the return spring 172 to move to the extrusion state. And when the connecting part 17 moves to the left, it will drive the electric saw 12 to move at the same time, prompting the electric saw 12 to gradually move to the left when logging the round bamboo, so that the electric saw 12 can cover the entire surface of the round bamboo faster, thereby accelerating the logging process.

[0046] When the electric saw 12 finishes logging the round bamboo, the servo motor 16 will drive the rotating part 14 to rotate in the reverse direction through the rotary gear 15. When the rotating part 14 rotates in the reverse direction, it will drive the extrusion block 171 to rotate in the reverse direction through the connecting part 17. When the extrusion block 171 rotates in the reverse direction, it will gradually disengage from the tooth blocks of the arc-shaped rack 18. At this time, the return spring 172 in the compressed state can drive the connecting part 17 to perform a reset movement inside the rotating part 14, so that the connecting part 17 can drive the electric saw 12 back to the initial state.

[0047] When the equipment fells the inclined round bamboo, the operator can start the electric push rod 19, so that the output shaft of the electric push rod 19 can drive the fixing part 110 to move upward. When the fixing part 110 moves upward, it can drive the connecting frame 111 to move simultaneously through the slider 112. When the connecting frame 111 moves upward, it will drive the rotating frame 11 to move simultaneously. Since the rear side of the rotating frame 11 is rotatably connected to the top of the rear side of the pushing cart 1, and when the rotating frame 11 moves upward, it will tilt upward. When the rotating frame 11 tilts upward, it can drive the electric saw 12 to move simultaneously. At this time, the electric saw 12 can fell the round bamboo in an inclined state, so that the bottom of the felled round bamboo is in a smooth state, avoiding potential safety hazards to people when walking.

[0048] Reference Figure 7 and Figure 8 As shown in the figure, when the felling equipment is in the initial state, the pushing frame 21 is slidably connected to the left side of the outer surface of the guiding frame 2, the connecting spring 22 is in a natural and relaxed state, and the rotating frame 24 has not been squeezed by the moving frame 23;

[0049] As the rotating part 14 rotates, it will drive the fixing bar 27 to rotate simultaneously. When the fixing bar 27 rotates, it will drive the rotating column 26 to rotate simultaneously. When the rotating column 26 rotates at the bottom of the center of the support frame 25, it will drive the rotating frame 24 to rotate simultaneously. When the rotating frame 24 rotates, the outer surface of the left end of the rotating frame 24 will touch the outer surface of the top of the moving frame 23 and drive the moving frame 23 to be pushed to the right. When the moving frame 23 is pushed to the right, it will drive the pushing frame 21 to move simultaneously. When the pushing frame 21 slides to the right on the outer surface of the guiding frame 2, it will move the connecting spring 22 to a compressed state, and when the pushing frame 21 slides to the right, it can push the felled round bamboo to the right, enabling the operator to more easily predict and control the falling direction of the round bamboo, thereby avoiding accidental injuries to people caused by the random falling of the round bamboo.

[0050] When the round bamboo felling is completed, the rotating part 14 will drive the rotating column 26 to rotate in the reverse direction through the fixing bar 27. When the rotating column 26 rotates in the reverse direction, it will drive the rotating frame 24 to rotate in the reverse direction simultaneously. When the rotating frame 24 rotates in the reverse direction, it will cause the outer surface of the rotating frame 24 to separate from the outer surface of the top of the moving frame 23. At this time, the compressed connecting spring 22 will cause the pushing frame 21 to slide to the left, and when the pushing frame 21 slides to the left on the outer surface of the guiding frame 2, it will drive the moving frame 23 to reset and slide simultaneously.

[0051] Reference Figures 9 to 11As shown in the figure, at this time, the staff starts the punching machine 36, causing the front end of the punching machine 36 to rotate. When the rotating column 26 rotates, it will drive the conveyor wheel 3 to rotate at the same time. When the conveyor wheel 3 rotates, it will drive the rotating disk 32 to rotate at the same time through the conveyor belt 31. When the rotating disk 32 rotates on the upper surface of the support member 34, it will drive the extrusion column 321 to rotate at the same time. Since the outer surface of the extrusion column 321 is in extrusion fit with the inside of the rear side of the transmission member 33, as the extrusion column 321 rotates, it will drive the transmission member 33 to move forward. When the transmission member 33 moves forward, it will drive the output end of the telescopic member 35 to move at the same time. As the output shaft of the telescopic member 35 moves forward, it will drive the punching machine 36 to move at the same time. When the punching machine 36 moves forward, it can punch the harvested round bamboo, so that the perforated round bamboo can be conveniently connected in series by ropes, so that the round bamboo can be transported more compactly and stably during water transportation, reducing the loss caused by the rolling or scattering of the round bamboo.

[0052] When the punching of the round bamboo by the punching machine 36 is completed, the rotating disk 32 will then drive the extrusion column 321 to rotate, causing the extrusion column 321 to extrude the transmission member 33 to cause the transmission member 33 to move backward. When the transmission member 33 moves backward, it drives the punching machine 36 to move at the same time, causing the punching machine 36 to slide out of the round bamboo for reset movement.

[0053] Reference Figure 12 and Figure 13 As shown in the figure, when the rotating frame 24 swings counterclockwise, it will drive the connecting rod 43 to swing at the same time. Since the outer surface of the connecting rod 43 is in extrusion fit with the inner side of the fixed frame 42, when the connecting rod 43 swings counterclockwise, it will fit against the inclined surface of the fixed frame 42 and cause the fixed frame 42 to move downward. When the fixed frame 42 moves downward, it will drive the sliding frame 41 to move at the same time. When the sliding frame 41 moves downward inside the support block 4, the conical shape at the bottom of the sliding frame 41 can be inserted into the soil, thus providing a stable support point for the harvesting equipment to reduce the shaking and deviation during the harvesting process, and also making the cut surface of the round bamboo flat and improving the harvesting accuracy.

[0054] When the harvesting of the round bamboo is about to be completed, the outer surface of the connecting rod 43 will fit against the inclined surface on the left side of the fixed frame 42, causing the fixed frame 42 to move upward. When the fixed frame 42 moves upward, it will drive the sliding frame 41 to move at the same time inside the support block 4, causing the conical shape at the bottom of the sliding frame 41 to be pulled out of the soil.
