When explaining the operational relationship of the present invention configured as described above with reference to FIGS. 3 to 12 are as follows.

Twig cutting machine 100 according to the present invention, as shown in Figures 3 and 11, 12, the wheel unit 160 is installed at the lower side can be moved, after the user moves to the desired position wheel unit 160 Stepping on the brake pedal 180 installed on the), the turning angle of the wheel unit 160 and the rolling motion of the wheel are braked together by the dual braking means installed on the wheel unit 160, so that the tree branch cutter 100 is stopped in place. There will be.

12 (a) is a state in which the dual braking means is released, so that the wheel cutting machine 100 can be freely moved by not braking the wheel 161 of the wheel unit 160. At this time, since the upper locking projection 171 is not bitten by the cogwheel 167, and the wheel brake 173 is in a non-contact state with the top surface of the wheel 161, the rotation of the wheel is free so that the tree branch cutter 100 ) Is free to move.

In this state, if you want to stop the movement of the tree branch cutting machine 100 at a place necessary for work, if you step on the rear pedal 182 of the brake pedal 180, as shown in FIGS. 11 and 12 (B), , Between the front and rear pedal portions (181,182) is installed as a hinge bolt 185, the rear pedal portion 182 is lowered to the lower side.

At this time, when the radius from the portion where the hinge bolt 185 is installed to the front cam portion 183 and the radius from the hinge bolt 185 to the lower cam portion 184 are installed in a cam shape and lower the rear pedal portion 182 , The front cam portion 183 pushes the vertical portion 174 forward, and the lower cam portion 184 is manufactured to a dimension capable of pressing the wheel brake portion 173 downward.

Therefore, as the vertical portion 174 is pushed forward by the operation of stepping the rear pedal portion 182 downward to be inclined, the locking protrusion 171 formed on the upper tip portion is bitten by the gear portion of the gear 167. (167) is impossible to rotate, the wheel mounting bracket (116) and the wheel bracket (162) are in a fixed state, making it impossible to turn the wheel (161), and the wheel brake (173) pressed against the lower cam (184) is a wheel ( By braking 161), the rolling motion of the wheel becomes impossible.

When the rear pedal portion 182 is lowered to be inclined downward as above, when the front cam portion 183 pushes the vertical portion 174, the vertical portion 174 is elastically pushed from the opposite side of the vertical portion 174. The front cam portion 183 is tightly fitted to the vertical portion 174, and the lower cam portion 184 is also tightly pressed while pushing the wheel braking portion 173, thereby maintaining the state in which the rear pedal portion 182 is inclined downward. .

When the engaging protrusion 171 is bitten by the cogwheel 167, the rotation of the cogwheel 167 becomes impossible, and the wheel mounting table 116 is fixed to the top of the cogwheel 167, thereby cutting the branches. (100) The turning of the wheel unit 160 installed on the lower side becomes impossible, and in addition, the wheel braking unit 173 pressed by the lower cam unit 184 presses the upper surface of the wheel 161 to turn the wheel unit ( 160) is to double brake.

As shown in the above, when the tree branch cutting machine 100 is moved to a storage place or another work place while the tree branch cutting operation is performed while the tree branch cutting machine 100 is fixed to a certain place, the figure 11 and As shown in (a) of FIG. 12, the front pedal portion 181 of the brake pedal 180 is pressed to descend downward.

When the front pedal portion 181 descends obliquely, the front cam portion 183 is erected vertically in an inclined state, so that the front cam portion 183 is retracted as much as the brake plate supported by the spring 169 As the 170 is pushed to the rear, the engaging projection 171 on the upper side is released from the gear portion of the gear wheel 167, and the gear wheel 167 is freely rotated.

In addition, the height of the wheel braking portion 173 pressed by the lower cam portion 184 is also increased by a predetermined height, so that the wheel braking portion 173, which was in contact with the wheel braking portion 173, is separated from the upper surface of the wheel 161. The wheel 161 is free to rotate.

As described above, in the state in which the twig cutter 100 is stopped from moving in the working place, the inlet side of the input pipe 110 is high and the side connected to the cutting chamber 115 is formed low, as in FIGS. 4 to 6. When the inner bottom surface of the input pipe 110 is inclined and a twig is fed into the input pipe 110, the twig slides down toward the cutting chamber 115 by its own weight.

At this time, the upper end of the input tube 110, the upper hanging hole 113 is formed to reduce the upper height (H) of the space that passes to the cutting chamber 115 side, the thicker branches than the height (H) is the upper hanging hole It is caught in (113) and cannot enter the cutting chamber (115).

The branch having a thickness thinner than the height (H) is lowered by sliding down by its own weight, and then the front end thereof comes into contact with the branch press 130, which is seen in FIGS. 5 to 7 As shown in the virtual line of FIG. 5, the upper part of the hinge bracket 135 on both sides is hingedly installed on the side wall of the input tube 110, and the sliding tree branches push the twig pusher 130. It sounds like knowledge.

At the same time as being lifted in a hinged manner, the rotating body 131 is installed to be idle at the lower part of both hinge brackets 135, so that the rotating body 131 rotates in the direction of the arrow in Fig. 5, and The branches are inserted between the bottom surfaces of the input tube 110, and the twig press 130 is made of metal and has a predetermined weight (made of 6 kg), so it is placed on the top of the branches by its own weight. And the tree branches are pressed down.

In this way, although the twig press 130 having a predetermined weight presses the twig, the bottom surface of the input tube 110 is inclined and the rotating body 131 is centered around the rotation axis 141 of the twig press 130. As the idling, the tree branches slide down by its own weight until its tip reaches the rotating cart 140, and slides while the tip of the branches touches the outer surface of the cylindrical drum body 143 of the rotating cart 140. This will stop.

At this time, since the rotating cart 140 is rotated at a high speed by the power of the driving unit 150, the tip of the branch contacting the outer circumferential surface of the cylindrical drum body 143 is rotated by the frictional force with the rotating cart 140 It is pulled down in the downward direction in which the 140 rotates. As shown in FIG. 8, the front end portion of the tree branch is next to a plurality of rows of non-slip guide grooves 145 and 147 formed in the rotating cart 140 and the non-slip guide groove 147. The non-slip guide grooves 145 and 147 are correctly inserted in the direction in which they are formed without slipping.

In this state, since the rotating cart 140 continues to rotate, when the groove 142 matches the distal end of the twig as shown in FIG. 5 in the process of rotating the rotating cart 140, a space for the twig to be further secured is required. As it goes further toward the groove portion 142, it enters inside the blade 144.

As the tip of the branch enters the inside of the blade 144 and the rotating cart 140 continues to rotate, as shown above, the lower end of the branch is supported by the cutting base 146, so that the tip of the branch rotates. It is cut by the blade 144 of the kata 140, and the cut piece of wood is rotated as the rotating kata 140 rotates while being contained in the recess 142.

At this time, the lower part of the rotating cart 140 is provided with a cutting thread cover 114 in which the lower side has a circular shape with a clearance so as not to reach the rotating rotating cart 140, so that the recess 142 is the front input tube 110 When cutting toward the), the tip of the tree branch is cut and cut, and when the groove 142 containing the piece of wood rotates toward the discharge pipe 120, the rotating cart 140 rotates to cut the groove in the groove 142. The piece of wood is discharged to the outside through the discharge pipe 120 by the rotational force of the rotating cart 140.

From above, the tree branch pusher 130 has an arc-shaped presser 134 that directly presses the tree branch, and is formed in a low arc in the middle and high arc on both sides, so that the bottom surface and arc shape of the input tube 110 as shown in FIG. 6. A space having a high center is formed between the presses 134 to induce the tree branches 101 to come from the inside of the input tube 110 to the center.

And, as shown in FIG. 5, the applicant H of the present invention is made of 10 cm in height (H) between the bottom side of the upper side opening 113 and the input tube 110, so that only the wooden branches having a thickness of 10 cm or less can be cut. It is possible.

In addition, the wood cutting pieces cut in the cutting chamber 115 by the upper hanging hole 113 is prevented from protruding toward the inlet side of the input tube 110, and the tree branch pusher 130 of the input tube 110 The rotation to the entrance side is also blocked, and even by the twig press 130, the wood chips cut in the cutting chamber 115 are blocked from protruding toward the entrance side of the input tube 110.

As shown in FIG. 4, the upper portion of the flexible shatterproof barrier 112, such as a rubber plate, is coupled to the upper portion of the inlet pipe 110, so that the lower portion is stretched to the lower side in the form of a foot to cut the branches from the cutting chamber 115 During the cutting process, scattering materials such as dust or very small pieces of wood are prevented from coming out through the input tube 110.

In addition, the wood chips cut in the cutting chamber 115 are discharged to the outside through the discharge pipe 120. At the end of the discharge pipe 120, a branch discharge direction adjusting means is installed to cut the wood chips. The discharge point can be selected and adjusted by the user.

That is, the branch discharge direction adjustment means, as shown in FIGS. 3, 4 and 9, 10, the discharge pipe head 121 is freely installed at the end of the discharge pipe 120 to rotate the discharge pipe head 121, The discharge pipe head 121 is free to rotate at the end of the discharge pipe 120 by several guide portions 123 installed on the flange portion 122 at the lower side of the discharge pipe head 121. After completing the adjustment, the fixing member 124 is screwed to fix the adjusted position.

Next, to adjust the angle of the extension head 126 installed at the end of the discharge pipe head 121, the discharge pipe head 121 is formed to be bent in an arc shape, the extension head 126 has an arc-shaped hole 125 It is formed, by connecting the side of the arc-shaped long hole 125 and the discharge pipe head 121 corresponding to it with a guide bolt 127 to loosen the guide bolt 127 loosely, the imaginary line and arrow of FIG. 9 When the guide bolts 127 are tightened by adjusting the appearance and extension of the extension head 126, the adjustment is completed, and the cut piece of wood discharged through the discharge pipe 120 according to the angle at which the extension head 126 is installed is far away.
