The power transmission mechanism 23 that transmits the driving force from the motor 21 to the rotary blade 31 is configured by meshing with the two gears 26c (see FIG. 5).

  Accordingly, when the motor shaft gear 22a formed on the motor shaft 22 is rotated by the rotational driving force of the motor shaft 22, the rotational driving force of the motor shaft gear 22a is transmitted to the intermediate shaft 25 via the first gear 25c, Further, it is transmitted to the second gear 26 c via the intermediate shaft gear 25 d of the intermediate shaft 25, and the rotary blade shaft 26 is driven to rotate. When the rotary blade shaft 26 is rotationally driven, the rotary blade 31 installed on the rotary blade shaft 26 is rotated.

  The garden shredder 10 according to the present embodiment includes a breaker mechanism that automatically stops the supply of electric power to the motor 21 when the motor 21 is overloaded while the material to be cut is being cut. can do. When the supply of electric power to the motor 21 is stopped due to an excessive load applied to the motor 21 and the power supply of the garden shredder 10 is turned off, as shown in FIG. 2 and FIG. By pushing the breaker device 29 installed in the vicinity of the switch device 27, the supply of power to the motor 21 is resumed. With such a configuration, the garden shredder 10 according to the present embodiment can protect the motor 21 and the like from failure due to overload, and the operator can safely use the garden shredder 10 according to the present embodiment. Can be done.

  The rotary blade 31 and the fixed blade 33 are installed in a state of being inclined with respect to the insertion direction of the material to be cut from the insertion port 11 and configured to cut the material to be cut that has been supplied in cooperation. .

  As shown in FIG. 6, the rotary blade 31 includes two rotary cutting blades 31 a and 31 b that extend symmetrically from the center of the rotation axis. The ridge line of the outer peripheral side blades of the rotary cutting blades 31a and 31b is formed so as to be located rearward with respect to the rotation direction of the rotary blade 31, and the rotary blade 31 is substantially S-shaped in plan view as shown in FIG. It has a shape. With this configuration, once the rotary cutting blades 31a and 31b of the rotary blade 31 bite into the material to be cut and a cut is made, the material to be cut is gradually cut by the rotation of the rotary blade 31. The garden shredder 10 according to the present invention can cut a material to be cut with less force.

  In addition, as shown in FIG. 6, the fixed blade 33 is formed such that the edge line of the blade edge is curved toward the counter-rotating direction of the rotary blade 31 toward the outer peripheral side. The fixed blade 33 is installed in the vicinity of the rotary blade 31. The material to be cut introduced from the insertion port 11 is wound by the rotation of the rotary blade 31, moves to the position of the fixed blade 33, and is cut by being sandwiched between the rotary blade 31 and the fixed blade 33. It becomes.

  Moreover, since the garden shredder 10 which concerns on this embodiment is installed in the state which the rotary blade 31 inclined with respect to the injection direction of the to-be-cut material from the insertion port 11, the rotary cutting blades 31a and 31b of the rotary blade 31 are provided. Is easy to bite into the material to be cut, and the material to be cut that the rotary blade 31 bites into is easily drawn into the casing 13. Therefore, according to the garden shredder 10 according to the present embodiment, it is possible to reduce the frequency of the correction work (pushing work of the material to be cut) when the pull-in failure occurs in the material to be cut, so that the operator has less labor. Thus, the material to be cut can be cut.

  The material to be cut that has been cut by the rotary blade 31 and the fixed blade 33 falls into the space α for the discharge path below the rotary blade 31, and is further discharged from the discharge port 14 formed in the lower part of the casing 13. Then, the cut material to be cut is stored in the shredder box 15.

  The shredder box 15 can be taken out by pulling the shredder box 15 to the front side with the lever 16 for removing the shredder box 15 pushed upward. The material to be cut in the shredder box 15 can be discarded as garbage, used for compost, smoked chips, mulching, or the like, depending on the purpose of the operator.

  In the garden shredder 10 according to the present embodiment, the assembly shaft 18 and the two wheels 19 disposed between the two legs 17 supporting the garden shredder 10 are removed, and then the two legs 17 are directed upward. Further, the shredder box 15 that has been removed is covered with the garden shredder 10 from above so that it can be stored compactly. When used from the stored state, the assembly shaft 18 is disposed between the two leg portions 17, the assembly shaft 18 is inserted into the holes formed in the leg portions 17, and both ends of the assembly shaft 18 are inserted. The wheel 19 is fixed with a nut or the like.

  Note that the garden shredder 10 according to the present embodiment can be configured to include a push rod (not shown) for pushing the material to be cut.

  Heretofore, the basic configuration of the garden shredder 10 according to the present embodiment has been described. Next, the adjustment plate 40 according to the present embodiment will be described with reference to FIGS. 6 and 7.

  The adjustment plate 40 is configured to receive the inserted workpiece and adjust the distance from the rotary blade 31. As shown in FIG. 6, the adjustment plate 40 is installed at a position inside the casing 13 that does not overlap the fixed blade 33. Further, the adjustment plate 40 is installed so that the surface of the adjustment plate 40 that receives the material to be cut put into the insertion port 11 is orthogonal to the rotation shaft 26 of the rotary blade 31. The adjustment plate 40 includes an adjustment plate guide rib 41 that guides the movement of the adjustment plate 40. A spring 43 is disposed adjacent to the adjustment plate guide rib 41. Due to the elasticity of the spring 43, a cam contact portion 45 extending toward the motor 21 from the surface of the adjustment plate 40 that receives the material to be cut comes into contact with the cam 51, which will be described later, while making contact with the cam 51. Will be retained.

  As shown in FIG. 7, the cam 51 is installed adjacent to the adjustment plate 40. The cam 51 has a generally slender shape in cross section, and by rotating the cam 51, the adjustment plate 40 moves in the direction of the rotation axis of the rotary blade 31, and the distance from the rotary blade 31 can be adjusted. It is configured as follows. In other words, the distance from the rotary shaft 26 of the rotary blade 31 to the peripheral surface of the cam 51 is not constant due to the shape action based on the generally slender shape in cross section. Therefore, the cam 51 is configured to be able to move the position of the adjustment plate 40 in the direction of the rotation axis of the rotary blade 31 by rotating while maintaining a contact state with the cam contact portion 45 of the adjustment plate 40. ing. With such a configuration, the adjustment plate 40 can adjust the distance from the rotary blade 31.

  Note that the cam 51 according to the present embodiment is rotated by an operator turning a dial 53 for rotating the cam 51 (see FIGS. 2 and 3). The cam 51 is configured to be able to come into contact with at least two points of the cam contact portion 45 of the adjustment plate 40, and can hold the adjustment plate 40 at the position.

  The dial 53 also functions as a lock button for the cam 51, and is configured so that the cam 51 can be positioned in multiple stages as shown in FIGS. The cam 51 rotates according to the rotation of the dial 53.

  The adjustment plate 40 according to the present embodiment has been described above. Next, an operation example of the garden shredder 10 according to the present embodiment will be described.

  In the garden shredder 10 according to the present embodiment, the operator turns the dial 53 to a predetermined position in order to obtain a material to be cut that has been cut to a desired cutting size. As described above, when the dial 53 is rotated so that the position of the desired dial 53 is reached, the cam 51 is rotated according to the rotation of the dial 53. When the cam 51 rotates, the lower surface of the cam contact portion 45 of the adjustment plate 40 comes into contact with the peripheral surface of the cam 51, and the adjustment plate 40 is always pushed toward the cam 51 by the elasticity of the spring 43. Since the contact is made with the cam 51 while pressure is applied, the adjustment plate 40 is held at this position. Therefore, the distance between the adjusting plate 40 and the rotary blade 31 can be adjusted by operating the dial 53.

  As described above, on / off control is performed by the operator pressing the switch device 27, and power from an external power source (not shown) is supplied to the motor 21 when the switch device 27 is turned on. As a result, the motor shaft 22 of the motor 21 is driven to rotate. When electric power is supplied to the motor 21, the motor shaft 22 included in the motor 21 rotates, and the driving force is transmitted to the rotary blade 31 by the power transmission mechanism 23. And the rotary blade 31 will rotate at high speed.

  The operator inputs a material to be cut such as pruned branches and leaves into the casing 13 from the input port 11. The material to be cut introduced from the introduction port 11 is received by the adjustment plate 40 below the opening 12. The material to be cut received by the adjusting plate 40 is wound and rotated by the rotating blade 31 rotating at high speed, and the distance between the adjusting plate 40 and the rotating blade 31 is maintained between the fixed blade 33 and the rotating material 31. And is sandwiched between the rotary blade 31 and the fixed blade 33 and cut. At this time, the material to be cut moves to the position of the fixed blade 33 while maintaining the distance between the adjustment plate 40 and the rotary blade 31, and therefore the distance dimension between the adjustment plate 40 and the rotary blade 31 is approximately the same. It will be cut with the same dimensions. Therefore, according to the garden shredder 10 according to the present embodiment, by operating the dial 53, the cam 51 is rotated to adjust the distance between the adjusting plate 40 and the rotary blade 31, thereby easily cutting the workpiece. The dimensions can be adjusted.

  Thus, the material to be cut that has been cut by the garden shredder 10 according to the present embodiment is stored in the shredder box 15. And the cut material cut | disconnected by the garden shredder 10 which concerns on this embodiment is discarded as garbage, for example, is used for a compost, a chip for smoke, or a mulching etc. according to the use purpose of an operator. be able to.

  As mentioned above, although preferred embodiment of this invention was described, the technical scope of this invention is not limited to the range as described in the said embodiment.

  For example, in the garden shredder 10 according to the present embodiment, the cam 51 is used as a mechanism for moving the adjustment plate 40 in order to adjust the distance between the adjustment plate 40 and the rotary blade 31, but the scope of the present invention includes this. For example, the adjustment plate 40 may be moved by turning a screw using a screw, and the distance between the adjustment plate 40 and the rotary blade 31 may be adjusted. A specific example of such a configuration will be described with reference to FIGS. Here, FIG. 8 is a schematic vertical sectional view of an essential part showing an example of various modifications that the garden shredder according to the present invention can take, and FIG. 9 shows the use of the garden shredder according to the modification shown in FIG. It is the figure which illustrated the mode of time.

  The garden shredder 100 according to the modified embodiment shown in FIG. 8 is a realization of the garden shredder 10 according to the present embodiment described above with a simpler configuration and is formed following the charging port 111 formed above. The path 112 is configured to face obliquely downward. In addition, a fixed blade 133 fixed in the vertical direction and a rotary blade 131 that rotates along the fixed blade 133 in a vertical plane are disposed at the end portion of the charging path 112.

  Further, an adjustment plate 140 formed in a plate shape is disposed further to the back of the installation position of the rotary blade 131 and the fixed blade 133 (on the right side in FIG. 8). The adjustment plate 140 is fixed to a long hole 113 a formed in the casing 113 in a state in which the position adjustment in the horizontal direction is possible by a chip length adjustment screw 141. That is, the position and adjustment of the rotary blade 131 and the fixed blade 133 are performed by moving the adjustment plate 140 in the horizontal direction (left and right direction in FIG. 8) along the long hole 113a with the tip length adjustment screw 141 loosened. The distance from the position of the plate 140 can be adjusted, and the position of the adjustment plate 140 is fixed by tightening the tip length adjusting screw 141 in a state where the adjustment plate 140 is in a desired position. The distance between the position of the blade 131 and the fixed blade 133 and the position of the adjustment plate 140 can be determined.

  8 and 9, the induction cam 121 is connected to the motor shaft 22 of the motor 21 for rotating the rotary blade 131 via a power transmission mechanism (not shown). The outer peripheral surface of the guide cam 121 is configured to repeatedly move in and out of the charging path 112 by rotating the guide cam 121 in conjunction with the rotary motion of the rotary blade 131. The guide cam 121 is installed to move the material to be cut, which has been moved to the bottom surface side of the input path 112 by cutting with the rotary blade 131 and the fixed blade 133, so as to stably contact the adjustment plate 140. More stable cutting can be realized. However, in the garden shredder according to the present invention, the guide cam 121 is not an essential configuration and can be omitted.

  Therefore, as shown in FIG. 9, the material W to be cut that has been input from the input port 111 formed above is guided obliquely downward along the input path 112, and the lower end of the material W to be cut The portion comes into contact with the adjustment plate 140. The workpiece W is fixed and positioned by contacting the adjusting plate 140. In such a state, the rotary blade 131 rotates and bites into the workpiece W, and the rotary blade 131 and the fixed blade 133 are further rotated. Will cut the workpiece W in cooperation with each other. When cutting, the workpiece W moved to the bottom surface side of the feeding path 112 by cutting with the rotary blade 131 and the fixed blade 133 is moved upward by the guide cam 121 so that the adjusting plate 140 is stably applied. Therefore, more stable cutting is performed. Further, at this time, the adjusting plate 140 is set to have a desired interval by adjusting the distance between the rotary blade 131 and the fixed blade 133 by using the chip length adjusting screw 141 and the long hole 113a. Therefore, the cutting length of the material to be cut W is substantially constant at a desired length. That is, according to the garden shredder 100 according to the modified example illustrated in FIGS. 8 and 9, it is possible to easily realize adjustment of cutting dimensions of branches and leaves according to the purpose of cutting the pruned branches and leaves. It has become.

  In the above, the various forms which the garden shredder which concerns on this invention can take were demonstrated using FIGS. However, various modifications or improvements can be added to the above-described embodiments and modifications.

  For example, in the garden shredder 10 according to the present embodiment, the adjustment plate 40 is a plate-like one, but the adjustment plate according to the present invention is not limited to such a configuration, Any material that can receive the cutting material and adjust the distance from the rotary blade 31 may be used.

  Further, for example, with respect to the positional relationship between the rotary blades 31 and 131 and the fixed blades 33 and 133 in the above-described embodiments and modifications, the arrangement relationship can be reversed.

  It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
