When the movable frame 130 is moved upward along the diagonal direction?, The rotation preventing member 159c moves over the inclined surface of the rotating gear 173 so that the rotating gear 173 is rotated . Since the position fixing force of the position fixing portion 180 for fixing the position of the movable frame 130 is greater than the contact force between the slant surface of the rotary gear 173 and the rotation preventing member 159c, 159c are raised in the upper direction Y as they are in contact with the toothed surfaces of the rotary gear 173 and overrun the toothed surfaces of the rotary gear 173 so that the rotary gear 173 is not rotated.

5 and 6 are views for explaining a process of forming a cutting groove in a sap of the present invention.

1 to 6, a process of forming a cutting groove in a sap of the present invention will be described.

First, the depth of insertion of the drill 151 inserted into the sapwood 1 is preset by the depth adjusting means 157 so as to correspond to the thickness of the skin 1a of the sapwood 1, The maximum rotation angle of the groove forming part 150 with respect to the rotation plate 153b is preset by the rotation angle setting member 153e so as to correspond to the thickness of the skin surface 1a of the sapwood 1.

5, as the driving motor 161 of the movement driving unit 160 rotates in the normal direction, the ball screw 166 rotates and the ball screw 166 is interlocked with the rotation of the ball screw 166, The groove forming part 150 is moved downward in the diagonal direction? By the moving guide of the second moving guide member 140 at the groove position. At the same time, the rotation motor 155 of the cut-off groove forming unit 150 rotates under the control of the drive circuit unit, and the drill 151 rotates. At this time, the rotation plate 153b of the cut-off groove forming unit 150 is rotated from the rotation base block 153a by a rotation angle set by the rotation angle setting member 153e according to the elastic force of the spring member 153f So that the drill 151 moves along the circumference of the sap tube 1 in conjunction with the diagonal movement of the cutting groove forming part 150 so that the surface 1a of the sap tube 1 is constantly Width, length and depth.

The drill 151 forms a first incision groove in the skin 1a of the sapwood 1 as the incision groove forming part 150 continuously moves downward along the diagonal direction?

By the movement guide. At this time, during the upward movement of the cutting groove forming portion 150 in the diagonal direction (?), The rotation preventing member 159c of the step moving force transmitting means 159 rides over the toothed inclined surface of the rotary gear 173 The position of the moving frame 130 is maintained by the position fixing force of the position fixing portion 180 because the rotation gear 173 does not rotate.

When the cutout groove forming part 150 is moved upward in the diagonal direction so that the moving block 152 contacts the upper switch 167, the first switch 167, which is generated by the upper switch 167, The driving motor 161 of the movement driving unit 160 is stopped by the control of the driving circuit unit based on the position detection signal and the process of forming the first incision groove 2 in the sapwood 1 is completed. At the same time, the driving circuit unit performs the set power saving mode.

Meanwhile, the driving circuit part counts the time while the power saving mode is performed, switches to the driving mode when the set time has elapsed, and controls the incision groove to be formed in the sapwood 1 through the above- And controls the driving of the forming unit 150 and the movement driving unit 160, respectively. As a result, the driving circuit unit repeatedly performs the power saving mode and the driving mode so that the incision grooves 2 are formed in the sapwood 1 at predetermined intervals, ), Respectively.

The apparatus for forming the incision grooves in the sapwood according to an embodiment of the present invention automatically cuts the incision grooves 2 at predetermined intervals in the sap tree 1 so that the sap flows out from the sap tree 1 Thereby minimizing the labor cost, the working time and the worker's effort for collecting the sap, thereby increasing the total daily production of the sap and the total production over a certain period of time. Particularly, the apparatus for forming an incision groove in a sap tree according to an embodiment of the present invention is characterized in that the sap is formed in a diagonal direction with respect to the sap tree 1 so that the sap flowing from the incision groove 2 flows smoothly into the sap- By forming the incision groove 2, it is possible to increase the collection efficiency of the liquid and to further increase the total daily production amount of the liquid and the total production amount for a certain period of time.
