Description
Technical field
This technology relates to the bamboo felling machine of felling bamboo.
Background technology
The half of world's bamboo product is in China, and Chinese half bamboo product is in Anji.So there be saying of " world's bamboo seeing China, and China Bamboo sees Anji ".Applicant, by Anji on-the-spot investigation, finds that " transport " mode of bamboo is very special.
Because bamboo grows ground automobile is difficult to pass through, after bamboo felling, general " slipping by slope " method that adopts slips under mountain from mountain.When slipping by slope, down, small end, utilizes the gravity of bamboo under hillside slides into mountain from the hilltop upward to the large end of bamboo.This method is very effective, has saved freight charges, time saving and energy saving, and transport efficiency is high.
The existing plant equipment to bamboo felling is mostly saw-blade type, adopts saw blade sawed-off to bamboo.This saw-blade type bamboo sawing machine belongs to makes a cart behind closed doors, and reckons without the special means of transportation of bamboo at all, without the possibility of practical application.Specifically, due to the plane that sawing face is vertical with bamboo length direction, when slipping by slope, this sawing face is positioned at bamboo glide direction foremost, the thrusts such as its rock easily and on hillside collide, not only can hamper the downslide (downslide preventing bamboo can be caused time serious) of bamboo, also can cause the cracking of bamboo.
Summary of the invention
The object of this technology is to provide and a kind ofly cuts down that efficiency is high, time saving and energy saving, the end of cutting down out is in the bamboo felling machine being suitable for bamboo and slipping by slope the taper of downslide.
Bamboo felling machine described in this technology, it comprises frame, and rotation is arranged in frame, is positioned at two rotors of same plane, and drive the driving mechanism that two rotors rotate, the periphery of two rotors has helical blade.
The beneficial effect of this technology: the bamboo between two rotors is cut owing to adopting rotor, so the end of bamboo is tapered after cut-off, when this tapered end contacts with the thrust on hillside, thrust produces the component perpendicular to bamboo axis direction to downslide bamboo, this component can make the large end of bamboo move in the direction perpendicular to bamboo axis, thus avoid thrust, avoid the stop of thrust to downslide bamboo, simultaneously, thrust the active force of bamboo is also reduced on bamboo axis direction, reduce the possibility of the large end cracking of bamboo.
Above-mentioned bamboo felling machine, the axis being parallel of two rotors or not parallel, rotor is taper or cylindricality, and blade is continuous or discontinuous; Preferably two rotor axis are not parallel, and the angle between them is 20 °-60 °.During use, bamboo enters from one end that opening between two rotors is larger, more convenient cutting bamboo.
Above-mentioned bamboo felling machine, the rotation direction of two rotors is identical or contrary.
Above-mentioned bamboo felling machine, the rotation direction of any one rotor meets with the hand of spiral of this rotor cutter: the cutting force that this rotor cuts bamboo is consistent in the direction of feed along the axial thrust load on rotor axis and bamboo.Like this, this axial thrust load can drive this rotor to move along the opposite direction with bamboo direction of feed, in other words, is conducive to bamboo and moves relative to rotor along direction of feed.
Above-mentioned bamboo felling machine, described driving mechanism comprises the driven gear be arranged on rotor, and the driving gear simultaneously engaged with two driven gears is arranged in frame, and is connected with its actuating unit rotated of drive.
Above-mentioned bamboo felling machine, described driving mechanism comprises the driven gear be arranged on rotor, and two driven gears are meshed, and driving gear engages with one of them driven gear; Driving gear is arranged in frame, and is connected with its actuating unit rotated of drive.
Above-mentioned bamboo felling machine, described driving gear, driven gear are bevel gear, spur gear or helical gear.
Above-mentioned bamboo felling machine, frame comprises the stay pipe that vertical direction extends, and rotor is positioned at the below sidepiece of stay pipe, and rotor axis is vertical with stay pipe; The middle and upper part of stay pipe is fixed with handle.Like this, during operation, the handle on hand-held top can operate, and rotor is positioned at bottom, can accomplish without the need to significantly bending over and cut the root of bamboo, more convenient to operate.

Fig. 2 is the schematic diagram of embodiment 2;
Fig. 3 is by the large end schematic diagram of bamboo of cutting down.
Fig. 4 is the cutting force schematic diagram of two rotors.
Embodiment
Bamboo felling machine shown in Figure 1, stay pipe 1 top vertically extended as a frame part is provided with actuating unit 2, and actuating unit can be gasoline engine or electromotor.The middle and upper part of stay pipe is fixed with handle 3.Power transmission shaft 4 is through stay pipe, and its upper end is connected with actuating unit output shaft, and lower end is provided with transition bevel gear 5.Transition bevel gear 7 and drive bevel gear 8 is fixed respectively at the two ends of reversing shaft 6.Transition bevel gear 7 engages with transition bevel gear 5, and drive bevel gear 8 engages with the driven wheel of differential 9 be arranged on a tool roller axis 13, and driven wheel of differential 9 engages with the driven wheel of differential 10 be arranged on another tool roller axis 14.Two tool roller axis 13,14 are positioned at same plane, the angle of left and right about at 45 °, tool roller axis 13,14 are respectively arranged with cylindrical rotor 11,12.The periphery of cylindrical rotor 11,12 has the blade 15,16 for cutting the bamboo between two rotors.Two tool roller axis are vertical with stay pipe, and rotation is arranged in frame.
During use, the bamboo of felling is between two rotors, and be substantially in the state perpendicular with two tool roller axis, actuating unit action, successively by the transmission of power transmission shaft 4, transition bevel gear 5, transition bevel gear 7, drive bevel gear 8, driven wheel of differential 9, driven wheel of differential 10, cylindrical rotor 11,12 is rotated backward, and namely the blade 15,16 on two rotors cuts the bamboo between two rotors.While cutting, two rotors along the bisector plane between two tool roller axis to two rotors between the larger one end of opening move, in other words, bamboo along the bisector plane between two tool roller axis to two rotors between the less one end of opening move, realize feeding, can complete cutting completely to the both sides of the bamboo with certain wall thickness, so latter two rotor rotates 90 ° around bamboo axis, just whole bamboo can be cut off.After cut-off, the end shape of bamboo 20 is see Fig. 3, and its bus 21 is camber line.
See Fig. 4, the blade 15 on cylindrical rotor 11 periphery is right-hand screw, and the blade 16 on cylindrical rotor 12 periphery is in left-hand screw, and cylindrical rotor 11 rotates by the clockwise direction 17 in Fig. 4, and cylindrical rotor 12 rotates by the counter clockwise direction 18 in Fig. 4.The cutting force F that cylindrical rotor cuts bamboo is consistent with the direction of feed of bamboo in the direction (the less one end of opening is pointed in one end larger from opening between two rotors) along the axial thrust load T on rotor axis.
Certainly, if the blade 15 on cylindrical rotor 11 periphery is left-hand screw, blade 16 on cylindrical rotor 12 periphery is in right-hand screw, cylindrical rotor 11 counterclockwise rotates, cylindrical rotor 12 clockwise direction rotates, and is equivalent to cylindrical rotor 11,12 right position described in epimere to exchange.Now, the cutting force F of cylindrical rotor cutting bamboo is also consistent with the direction of feed of bamboo in the direction along the axial thrust load T on rotor axis.
Or if the blade 15 on cylindrical rotor 11 periphery is right-hand screw, the blade 16 on cylindrical rotor 12 periphery is in right-hand screw, and cylindrical rotor 11 clockwise direction rotates, and cylindrical rotor 12 clockwise direction rotates.Now, the cutting force F of cylindrical rotor cutting bamboo is also consistent with the direction of feed of bamboo in the direction along the axial thrust load T on rotor axis.
Embodiment 2
Bamboo felling machine shown in embodiment 2 is see Fig. 2, and embodiment 2 is with the difference of embodiment 1: two rotors in embodiment 2 are two rotors in conical rotor 11,12(embodiment 1 is cylindrical rotor).
