FIG. 1 is an overall side view of an electric management machine (front rotor type) as an example of the present invention, and FIG. 2 is an overall perspective view of the electric management machine (front rotor type) as viewed from above.

  As shown in FIGS. 1-2, this electric management machine 1 is attached to the front part of the machine base 5 lower part via the tillage drive part 2 provided with the tillage shaft drive motor M1 mentioned later as a working machine. A rotary tiller 3 is arranged, and a rear part of the lower part of the machine base 4, and behind the rotary tiller 3, an axle case 7 attached to the rear part of the lower part of the machine base 4 penetrates and protrudes in the left-right direction. A pair of left and right wheels 9 are disposed as traveling wheels on the left and right ends of the axle 14 with which the axle drive motor M2 is linked.

  Further, a battery 6 is loaded on the machine base 4 via a sliding plate 5, and the steering handle 10 extends obliquely upward from the upper center on both side surfaces of the machine base 4 toward the rear of the machine body. It is installed.

  The rotary cultivator 3 includes a cultivating shaft 12 having a length in the left-right direction of the machine body, in which a plurality of cultivating claws 11 are planted on the peripheral surface at the tip of the cultivating drive unit 2.

  The tillage shaft drive motor M1 and the axle drive motor M2 are connected to the battery 6 via a wiring (not shown), and on the other hand, the axle drive motor M2 is driven by the power of the battery 6 and the axle 14 is rotated. The vehicle 4 is caused to travel by the wheels 4, and on the other hand, the tillage shaft drive motor M <b> 1 is driven, and the rotary tiller 3 performs the tillage work on the field through the rotation of the tiller shaft 12.

  In addition, the code | symbol 8 is a cover which covers the rotary tillage apparatus 3, and the code | symbol 16 is a gauge ring.

  The electric management machine 1 of the present invention can be switched between the front rotor type and the rear rotor type by the steering handle 10 together with the traveling direction of the machine body. FIG. 3 is a perspective view of an electric management machine that is a rear rotor type together with switching of the advancing direction of the airframe by turning the steering handle, and FIG. 4 shows a battery moving mechanism accompanying the turning of the steering handle. It is a front schematic diagram of the machine body upper part.

  As shown in FIGS. 1 and 2, a pivot 21 is provided in the upper center of the metal machine base 4, and both ends of the pivot 21 are directed from both side surfaces of the machine base 4 to the side. The proximal end portion of the steering handle 10 is attached to the protruding portion of the pivot 21. The steering handle 10 may be a known locking method (not shown) (for example, a locking tool provided between the steering handle 10 and the machine base 4 or a notch formed between the steering handle 10 and the pivot 21. And an appropriate method such as a protrusion).

  On the machine base 4, for example, a sliding plate 5 (made of metal) that is substantially equal to the left-right width of the machine base 4 and has a short front and rear length is attached. Are fixed by stoppers 22 such as bolts (in the illustrated example, two at each of the front and rear end portions of the sliding plate 5), and the battery 6 is mounted on the sliding plate 5 by bolt fixing or the like.

  The sliding plate 5 is fixed by the stopper 22 on the machine base 4 when the sliding plate 5 loaded with the battery 6 is the front rotary type body shown in FIGS. In the case of the rear rotary type aircraft shown in FIG. 3, the battery 6 is located between the rotary tiller 3 and the wheels 9 (the center of gravity of the aircraft is located on the center side of the aircraft). A hole (not shown) of the stopper 22 is formed on the upper surface of the machine base 4 at the position.

  For example, as shown in FIG. 4, the sliding plate 5 is slidable on the machine base 4 in the longitudinal direction of the machine body by a rail 23 formed between the machine board 4 and the slide board 5. The rail 23 includes, for example, a protruding portion 24 that protrudes downward in the front-rear direction of the bottom surface of the sliding plate 5 (not limited, but may be one in the center), and the front-rear side of the upper surface of the machine base 4. It is comprised from the groove part 25 which can be inserted in the convex part 24 formed over the direction.

  With this configuration, in the electric management machine 1, when it is desired to change the advancing direction of the front rotary type shown in FIGS. First, fixing of the steering handle 10 by the locking method is released, and the steering handle 10 is rotated from the wheel 9 side to the rotary tiller 3 side so as to draw an arc above the body centering on the pivot 21.

  Then, when the steering handle 10 is rotated to an arbitrary position as shown in FIG. 3, the steering handle 10 is fixed by the above-described locking method. As a result, the electric management machine 1 can easily switch the traveling direction to the rear rotary type with the wheel 9 side opposite to the front rotor type.

  In addition, when the airframe is a front rotary type, the center of gravity of the airframe is on the axle 14 side, so that the both ends of the sliding plate 5 are stoppered at a predetermined position where the wheel 9 side end is aligned with the vicinity of the end of the machine base 4. However, when the aircraft is switched to the rear rotary type by turning the steering handle 10 as described above, the center of gravity of the aircraft moves to the center of the aircraft, so the stopper 22 is removed, Both are fixed by a stopper 22 at a predetermined position on the upper surface of the machine base 4 where the battery 6 is located between the rotary tiller 3 and the wheel 9.

  As described above, when the airframe is switched to the front rotary type or the rear rotary type as the steering handle 10 is rotated, the slide plate 5 is slid to change the center of gravity to an appropriate position, thereby improving operability. Can be in a good state.

  The turning of the steering handle 10 and the sliding method of the sliding plate 5 are not limited to the above methods, and the turning of the steering handle 10 is in the horizontal direction of the machine body, and the sliding plate 5 is interlocked with the turning of the steering handle 10. May be slid. FIG. 5 is a schematic back view showing the structure around the rotating disk provided on the machine base.

  In this case, as shown in FIG. 5, for example, a rotating plate 31 that is rotatable in the horizontal direction of the machine body on the upper surface of the machine base 4 and a sliding plate 33 on the upper surface of the rotating plate 31 via an intermediate plate 32. The central portions of the rotating plate 31, the intermediate plate 32, and the sliding plate 33 are penetrated by the support column 34 and fixed to the machine base 4. Normally, the turntable 31 is fixed with a well-known fixing tool (not shown) appropriately provided on the machine base 4 or the like.

  Further, a rotating member 35 that rotates the outer peripheral surface of the column 34 with respect to the column 34 is attached to the outer peripheral portion of the column 34 where the rotating plate 31 is located, and only the rotating plate 31 is attached to the fuselage by the rotating member 35. On the other hand, it can be rotated in the horizontal direction. And the base end part of the steering handle 10 is attached to the front-and-rear end part (for example, the wheel 9 side) of the rotating disk 31.

  Further, the battery 6 having the stopper 22 is placed and fixed on the upper surface of the sliding plate 33 as described above, and the rail is interposed between the lower surface of the sliding plate 33 and the upper surface of the intermediate plate 32. 23 is formed in the same manner as described above.

  With such a configuration, in the electric power management machine 1, when the traveling direction of the body of the front rotary type is to be reversed by 180 degrees and the rear rotary type is to be switched, the lock mechanism 35 is released and the steering handle is released. 10, the rotating disk 31 is rotated 180 degrees in the horizontal direction with respect to the airframe, and the both are fixed again by the lock mechanism 35, so that the traveling direction is the same as that described above with the wheel 9 side opposite to the front rotor type. It may be easily switched to the rear rotary type. In addition, since the movement of the battery 6 in the adjustment of the center of gravity of the airframe in this case is the same as described above, the description thereof is omitted.

  In the electric management machine 1 of the present application, as described above, the steering handle 10 can be rotated to easily switch the traveling direction of the machine body, but the tilling shaft 12 including the tilling claws 11 in the rotary tilling device 3 Since the rotation direction of the airframe is changed in this way with respect to the plane, when the advancing direction of the airframe is switched in this way, for example, in the airframe advancing direction in the front rotary type before the switching, the tilling claw 11 rotates forward (advanced) with respect to the field scene. Whereas the tilling claw 11 entered the soil from the air into the soil), the tilling claw 11 rotated reversely with respect to the field scene (with respect to the advancing direction) in the rear body rotary direction after switching. The tilling claw 11 jumps out of the soil into the air), and if the work is performed in the reverse rotation state as it is, the tilling claw 11 is damaged.

  Therefore, when the traveling direction is switched as described above, conventionally, it is necessary to replace the tillage claw 11 for forward rotation, and the work of replacing each of the plurality of tilling claws 11 planted on the tillage shaft 12 is one by one. It was cumbersome and reduced workability. In addition, it is a well-known fact that the tilling nail | claw 11 has a rotation directionality, The description is abbreviate | omitted.

  As one of the means for solving the above problem, in the electric management machine 1 of the present invention, the tiller shaft drive motor M1 is used as the drive source of the rotary tiller 3, and the axle drive motor M2 is used as the drive source of the wheels 9. Since the drive source is separately installed and the tilling shaft 12 of the rotary tiller 3 is rotated by the tilling shaft driving motor M1, the tilling shaft driving motor M1 can be reversely rotated by a switch or the like (not shown).

  However, when the tillage shaft drive motor M1 does not have such a forward / reverse rotation function of the motor shaft, or when the motor shaft can be rotated forward / reversely, it does not function due to a failure or human error. There is also.

  Then, in the electric management machine 1 of this invention, the said problem is solved by providing a rotation direction change means in the tillage drive part 2. FIG. 6 is a front view of the rotary tiller showing the internal structure of the tillage drive unit (mission type), FIG. 7 is a perspective view of the tillage drive unit (mission type), and FIG. 8 is a tillage drive unit (mission) as a rotation direction changing means. It is a figure explaining rotation of a type.

  First, as shown in FIGS. 6 to 7, the tillage driving unit 2 of the rotary tiller 3 is fitted into a lower end portion of a fixing member 41 such as a hollow cylindrical shape (not limited) having an upper end portion fixed to the bottom surface of the machine base 4. Has been.

  The tillage driving unit 2 includes a tilling shaft driving motor M1 that is an electric motor connected to the battery 6 and a hollow cylindrical (not limited) shaft case 44 in which the motor shaft 43 is provided, and a lower end of the shaft case 44. Transmission type 47 that includes bevel gears 45 and 46, and a tilling shaft 12 in which a plurality of tilling claws 11 that penetrate from the transmission case 47 in the lateral direction of the machine body are planted. It can be.

  The lower end portion of the motor shaft 43 is connected to the bevel gear 45, and the tiller shaft 12 is fitted to the bevel gear 46 meshing with the bevel gear 45, so that the motor shaft 43 and the motor shaft 43 are driven by the tillage shaft drive motor M1. The tillage shaft 12 is driven through the bevel gears 45 and 46, and the tillage claw 11 rotates.

  The diameter of the upper end portion of the shaft case 44 (near the internal position of the electric motor 42) is slightly smaller than the diameter of the lower end portion of the fixing member 41, and the outer peripheral surface of the upper end portion of the shaft case 44 is the inner periphery of the lower end portion of the fixing member 41. The shaft case 44 is configured to be able to be rotatably fitted around the shaft core of the fixing member 41 in contact with the surface.

  In addition, bolt holes 47 and 48 that enable fixing of both the lower end portion of the fixing member 41 and the upper end portion of the shaft case 44 with a fastener such as a bolt 50 on the front surface of the machine body of the front rotary type. Is formed. Further, a bolt hole 49 is also formed in the shaft case 44 located on the back surface of the bolt hole 48 formed on the shaft case 44 side.

  Therefore, the rotation direction changing means of the tillage driving unit 2 includes the tilling shaft drive motor M1 and the motor shaft 43, the shaft case 44 that is rotatably fitted to the inner peripheral surface of the fixing member 41, the fixing member 41, and the shaft. It consists of a fixture for the case 44 (bolt holes 47, 48, 49 and bolts 50 formed on both).

  Here, as described above, when the steering handle 10 is rotated to change the advancing direction of the machine body from the front rotary type to the rear rotary type, for example, as shown in FIGS. The shaft case 44 including the tilling shaft 12 is rotated 180 degrees in the left-right direction around the axis of the fixing member 41, and the bolt hole 47 of the fixing member 41 and the bolt hole 49 of the shaft case 44 are The bolts 50 are fastened together at the position where they match.

  With this configuration, the tiller shaft 12 of the front rotary type before the change in the aircraft traveling direction was in the counterclockwise direction of rotation when viewed from the left side of the aircraft, whereas the rear after the change in the aircraft traveling direction. The rotary type tilling shaft 12 is rotated clockwise when viewed from the left side of the machine body by rotating the tillage driving unit 2.

  That is, the tilling shaft 12 rotates clockwise in the left side view of the airframe with respect to the traveling direction of the rear rotary type, so that the tilling claws 11 rotate forward (the tilling claws 11 are in the air relative to the traveling direction). The plowing operation can be smoothly performed without damaging the tilling claw 11. Contrary to the above, since the same operation as described above is performed when the advancing direction of the machine body is switched from the rear rotary type to the front rotary type, the description is omitted.

  The tillage driving unit 2 is not limited to the mission type. FIG. 9 is a perspective view of a tillage drive unit (mora type), FIG. 10 is a diagram for explaining the rotation of the tillage drive unit (mora type) as rotation direction changing means, and FIG. 11 is a detachable tillage drive unit (mora type).

  With such a configuration, when the steering handle 10 is rotated in the same manner as described above, for example, when the advancing direction of the aircraft is changed from the front rotary type to the rear rotary type, as shown in FIGS. 2, the motor case 53 including the tilling shaft 12 is rotated 180 degrees in the left-right direction around the axis of the fixing member 41, and the bolt hole 47 of the fixing member 41 and the bolt hole 49 of the rotating case 51 are rotated. The same effect as described above can also be obtained by fastening the bolts 50 at the positions where the two coincide with each other.

  The rotation direction changing means of the tillage driving unit 2 in the mora type is not limited to the rotation of the motor case 53 described above, and may be configured as follows. FIG. 11 is a perspective view of a detachable tillage drive unit (mora type), and FIG. 12 is a view for explaining attachment / detachment of the tillage drive unit (mora type) as a rotation direction changing means.

Bolt holes 63, 64, 65, 66 and bolts 67, 68 respectively formed on the upper end horizontal surface of the member 62 are configured.

  Therefore, the bolt holes 65 and 66 of the mounting member 62 are aligned with the bolt holes 63 and 64 of the support member 61, and both are fastened with bolts 67 and 68, so that the motor case 53 is supported via the mounting member 62. 61 is fixed.

  With such a configuration, when the steering handle 10 is rotated in the same manner as described above, for example, when the advancing direction of the aircraft is changed from the front rotary type to the rear rotary type, as shown in FIGS. The bolts 67 and 68 of the means are removed, and the fixing of the support member 61 and the mounting member 62 is released.

  Then, the motor case 53 including the tilling shaft 12 is rotated 180 degrees in the left-right direction, the bolt holes 63, 64 of the support member 61 are again aligned with the positions of the bolt holes 65, 66 of the mounting member 62, and the bolts 67, Even if the motor case 53 is fixed to the support member 61 via the mounting member 62 by fastening 68, the same effect as described above can be obtained.
