The rotation angle setting member 152e restricts the set maximum rotation angle of the rotation plate 152b. For example, the rotation angle setting member 152e may be made of a bolt having a certain length, in this case, the bolt is fastened to a bolt hole formed on the side of the rotation base block 152a, and the head of the bolt The part may protrude from the side of the rotation base block 152a by a length set to correspond to the set maximum rotation angle of the rotation plate 152b.

As such, the angle adjustment unit 152 rotates the rotation plate 152b according to the elastic force of the spring member, so that the drill 154 moves along the circumference of the sap tree 1, the skin of the sap tree 1 Adjust the angle between the drill 154 and the sap tree (1) to form an incision groove of a certain width and length in. That is, the drill 154 is moved in conjunction with the movement of the moving block 151. When the angle between the drill 154 and the sap tree 1 is fixed to an arbitrary angle, the drill 154 is There is a problem that it cannot move along the periphery of (1), and the depth of the cut groove cannot be uniformly formed. Accordingly, the present invention uses the angle adjustment unit 152 to adjust the angle between the drill 154 and the sap tree 1 in connection with the movement of the movable block 151 so that the drill 154 can be used as a sap tree ( While moving along the periphery of 1), an incision groove having a certain width, length, and depth can be formed in the sap tree (1).

The rotation motor 153 is installed on the rear surface of the angle adjustment unit 152, that is, the rotation plate 152b. The rotation drive shaft of the rotation motor 153 passes through the rotation plate 152b and is coupled to the drill 154. Accordingly, the rotation motor 153 rotates according to the drill driving power supplied from the driving circuit unit to rotate the drill 154, whereby the drill 154 adjusts the skin of the sap tree 1 to a certain width, length and The incision is made to the depth to form an incision groove. The rotation motor 153 may be surrounded by a motor housing (not shown) and protected from moisture. Here, the drill 154 may be changed to an end mill.

The depth adjustment means 155 is the angle adjustment unit 152, that is, the insertion of a drill 154 that is installed on the rotation plate 152b and is inserted into the sap tree 1 by contacting the skin of the sap tree 1 Adjust the depth (or the depth of the incision groove). The depth adjustment means 155 according to an example may include a depth adjustment guide 155a, and a pair of length fixing members 155b.

The depth adjustment guide 155a is formed of a bolt having a circular head and is coupled to a bolt hole provided in the rotating plate 152b. The depth adjustment guide 155a protrudes from the front surface of the rotating plate 152b facing the sap tree 1 by a length set according to the skin thickness T1 and T2 of the sap tree 1.

The pair of length fixing members 155b are fastened to the depth adjustment guide 155a with the rotation plate 152b interposed therebetween, thereby fixing the length of the length-adjusted depth adjustment guide 155a so as not to change.

The step movement force transmission means 156 is coupled to the upper surface 151b of the outer surface of the movement block 151 to move the rotation gear 173 of the step movement unit 170 according to the movement of the movement block 151. By rotating by one pitch, the moving frame 130 descends downward by one pitch of the first rack gear 171. The step movement force transmission means 156 according to an example protrudes from the fixing member 156a installed on the movement block 151 and the rotation gear 173 from the fixing member 156a to move in the first direction. The gear rotation member 156b for rotating the rotation gear 173, and the gear rotation member 156b protruding obliquely from the gear rotation member 156b to move in the second direction of the gear rotation member 156b opposite to the first direction movement. It includes a rotation preventing member (156c) for preventing rotation.

The fixing member 156a is coupled to the upper surface of the moving block 151.

The gear rotation member 156b protrudes above the second movement guide member 140 and the rotation gear 173 so as to have a predetermined length from one side of the fixing member 1156a. In this case, the gear rotation member 156b may protrude to have a smaller area toward the rotation gear 173 from the fixing member 156a in order to have a certain elastic force. When the downward movement direction of the movement frame 130 is assumed to be the front, the front edge portion of the gear rotation member 156b corresponding to the position of the rotation gear 173 is, the movement frame 130 When moving downward along the diagonal direction (θ), the rotation gear 173 is rotated by one pitch by pressing the vertical surface of the rotation gear 173.

The rotation preventing member 156c protrudes obliquely to have a certain angle and a certain length from the rear side of the gear rotation member 156b corresponding to the position of the rotation gear 173. When the movement frame 130 moves upward along the diagonal direction θ, the rotation preventing member 156c crosses the inclined surface of the rotation gear 173 so that the rotation gear 173 is not rotated. Do not. Here, since the position fixing force of the position fixing part 180 for fixing the position of the moving frame 130 is greater than the contact force between the inclined surface of the rotation gear 173 and the rotation preventing member 156c, the rotation preventing member ( 156c) rises in the upper direction Y as it contacts the inclined toothed surface of the rotating gear 173 and crosses the inclined toothed surface of the rotating gear 173 so that the rotating gear 173 is not rotated.

The cut groove forming part 150 according to the present invention may further include a lower switch 157.

The lower switch 157 is installed on the lower switch cover 157a installed on the outer surface 151a of the moving block 151. The lower switch 157 corresponds to the diagonal movement path of the cut-out groove forming part 150 moved in the longitudinal direction θ of the second movement guide member 140 and accommodates the lower switch cover 157a. It is installed in the space. When the lower switch 157 comes into contact with the lower switch movable member 169 while moving along with the downward movement of the moving block 151, the second switch 157 stops driving the driving motor 161. A position detection signal is generated and supplied to the driving circuit.

Meanwhile, similar to the above-described upper switch 168, the movable terminal 157b of the lower switch 157 is disposed to face downward. In this case, the lower switch 157 may also be wrapped by a waterproofing member that is waterproofed in one direction. As a result, the present invention, as described above, by installing each of the movable terminals 168b and 157b of each of the upper switch 168 and the lower switch 157 on the moving block 151 to face downward, Malfunctions of the upper switch 168 and the lower switch 157 can be prevented, and manufacturing cost can be reduced.

The process of forming an incision groove in the sap tree according to the present invention will be described as follows.

First, the insertion depth of the drill 154 inserted into the sap tree 1 is set in advance to correspond to the thickness of the skin of the sap tree 1 by the depth adjusting means 155, and the incision groove forming part The maximum rotation angle of 150 with respect to the rotation plate 152b is preset by the rotation angle setting member 152e to correspond to the thickness of the skin of the sap tree 1.

As the drive motor 161 of the moving drive unit 160 rotates in the forward direction, the ball screw 165 rotates, and the cut groove forming unit 150 is interlocked with the rotational motion of the ball screw 165 At the home position, the second movement guide member 140 moves downward in the diagonal direction θ by the movement guide. At the same time, the rotation motor 153 of the cut-out groove forming part 150 rotates under the control of the driving circuit part, so that the drill 154 rotates. At this time, the rotation plate 152b of the incision groove forming part 150 is rotated from the rotation base block 152a by the rotation angle set by the rotation angle setting member 152e according to the elastic force of the spring member. The drill 154 is interlocked with the movement of the incision groove forming part 150 in the diagonal direction (θ) and moves along the circumference of the sap tree 1 to move the epidermis of the sap tree 1 to a certain width, length, and depth. Form an incision groove.

As the incision groove forming part 150 continuously moves downward along the diagonal direction (θ), the drill 154 forms a first incision groove in the skin of the sap tree 1, and at the same time, the rotation The plate 152b adjusts the angle between the drill 154 and the sap tree 1 while being rotated toward the rotation base block 152a by elastic compression of the spring member.

Subsequently, when the cut-out groove forming part 150 moves beyond the set length of the cut-out groove 2, the step movement force transmission means 156 performs the rotation gear 173 of the step moving part 170. The moving frame 130 is rotated by a pitch, and thus, the moving frame 130 is lowered by one pitch of the first rack gear 171, and then lowered by the position fixing unit 180. The position of will be fixed. Accordingly, the position of the drill 154 is set to the position of the second cut-out groove lowered by one pitch of the first rack gear 171 from the first cut-out groove.

At this time, the rotation preventing member 156c of the step movement force transmission means 156 crosses the toothed slope of the rotation gear 173 while the cut groove forming part 150 moves upward in the diagonal direction θ. Since the rotation gear 173 does not rotate, the position of the moving frame 130 is maintained as it is by the position fixing force of the position fixing part 180.

Subsequently, when the cutout groove forming part 150 is moved upward in a diagonal direction θ so that the moving block 151 comes into contact with the upper switch 168, the first The driving motor 161 of the moving driving unit 160 is stopped under the control of the driving circuit unit based on the position detection signal, thereby completing the process of forming the first cutout groove 2 in the sap tree 1. At the same time, the driving circuit unit performs the set power saving mode.

Meanwhile, the driving circuit unit counts the time while performing the power saving mode, and when the set time elapses, it switches to the driving mode, and the cut groove is formed in the sap tree 1 through the above-described process. Controls the driving of each of the forming unit 150 and the moving driving unit 160. As a result, the driving circuit unit repeatedly performs the power saving mode and the driving mode so that the cut grooves 2 are formed at regular intervals in the sap tree 1 at a set time interval. ) Each drive is controlled.
