Definitions
- Patent Document 1 has a disadvantage that the working noise increases due to the vibration of the blade disk when the cutting width is defined by the rotating diameter of the blade or when the rotating diameter of the blade is increased in order to increase the cutting width. It was.
- an object of the present invention is to provide a work vehicle that eliminates the inconveniences described above and suppresses working noise even when the blade rotating diameter of the working part is increased.
- FIG. 1 is a conceptual diagram generally showing a work vehicle according to an embodiment of the present invention
- FIG. 2 is a top view of the work vehicle of FIG. 1
- FIG. 3 is a plan view of a work area where the work vehicle of FIG. is there.
- a lawn mowing working part (blade, specifically a rotary blade; hereinafter referred to as “working part”) 20 is attached near the center position of the chassis 12a of the vehicle 10, and an electric motor (prime motor. 22) (referred to as “motor”).
- the working unit 20 is connected to the work motor 22 and is rotationally driven by the work motor 22.
- the working unit 20 is connected to a working unit height adjusting mechanism 24 that can be manually operated by the user.
- the working unit height adjusting mechanism 24 includes a handle that can be operated by the user, and is configured such that the vertical height of the working unit 20 from the ground contact surface GR can be adjusted by turning the handle by hand.
- An on-board charging unit 30 and an on-board battery (battery) 32 connected to the on-board charging unit 30 are stored in the rear portion of the vehicle 10, and a pair of battery charging terminals 34 are attached to the chassis 12a so as to protrude forward of the front end position. .
- the battery charging terminal 34 is connected to the on-board charging unit 30.
- the work motor 22 and the travel motor 26 are also connected to the on-board battery 32 and are energized from the on-board battery 32.
- two left and right magnetic sensors 36L and 36R are disposed on the front side of the vehicle body 12, and one magnetic sensor 36C is disposed on the rear side, and each indicates a magnetic field magnitude (magnetic field strength). Is output.
- a storage box is provided near the central position of the chassis 12a.
- a microcomputer including a CPU, an I / O, a memory (ROM, EEPROM, RAM) and the like is provided on the circuit board 42 stored in the storage box.
- An electronic control unit (Electronic Control Unit, hereinafter referred to as “ECU”) 44 is mounted.
- an angular velocity sensor 46 that generates an output indicating an angular velocity (yaw rate) around the z axis (gravity axis) of the center of gravity of the vehicle 10 in the vicinity of the ECU 44, and x, y acting on the vehicle 10.
- An acceleration sensor 50 that generates an output indicating the acceleration in the three orthogonal directions of the z axis
- an azimuth sensor 52 that generates an output indicating the absolute direction according to the geomagnetism
- a GPS sensor 54 is provided that produces an output indicative of
- the outputs of sensors such as the magnetic sensor 36, the contact sensor 40, and the angular velocity sensor 46 and the outputs of switches such as the main switch 64 are sent to the ECU 44.
- the ECU 44 controls the traveling of the vehicle 10 by energizing the traveling motor 26 from the on-board battery 32 based on those outputs and outputting a control value to control the operation of the traveling motor 26.
- FIG. 5 is an enlarged view of the main part of FIG. 4, FIG. 6 is a sectional view taken along the line VI-VI of FIG. 5, and FIG. 7 is a blade disk 20a when a part of a member (second disk 80 described later) is removed from FIG.
- FIG. 8 is a perspective view of a part of the members. The blade 20b is not shown in FIGS.
- the second disk 80 has a substantially equilateral triangular shape in plan view, and the second disk 80 has a fixed position of 120 degrees equally spaced corresponding to three vertices of the equilateral triangle, More specifically, it is fixed to the blade disk 20a by welding (for example, spot welding or welding) at a fixed position 801 at equal intervals of 120 degrees near the three apexes.
- welding for example, spot welding or welding
- FIG. 6 there is a residual space between the blade disk 20a and the second disk 80 locally, more precisely, except for three equally spaced fixed positions 801 (not shown in FIG. 6).
- a space 82 communicating with the outside is formed between the part, that is, the peripheral edge of the second disk 80 and the blade disk 20a.
- a plurality of convex portions are formed on the surface of the blade disk 20a. That is, on the surface of the blade disk 20a, three first convex portions 20a5 having a generally rhombus shape in plan view are formed at equal intervals of 120 degrees around the central hole 20a4 through which the axis CL1 passes. Is done.
- a second convex portion 20a6 having a substantially rectangular shape in plan view extends between the formation positions of the first convex portions 20a5 in the circumferential direction so as to extend along the circumferential direction. Are formed at equal intervals. Accordingly, the first convex portion 20a5 and the second convex portion 20a6 are configured to increase the rigidity of the blade disk 20a.
- the second disk 80 has a substantially equilateral triangular shape in plan view, and the second disk 80 is provided on the blade disk 20a at fixed positions 801 at equal intervals corresponding to the apexes of the triangle.
- a space 82 that is locally communicated to the outside is formed between the blade disk 20a and the second disk 80, and the space can be operated to reduce high-frequency noise. It can be effectively suppressed.
- the second disk 80 is brought into contact with all of the three first convex portions 20a5, it may be one of the three, and further, may be brought into contact with all or a part of the second convex portion 20a6. May be.
- the second disk 80 is fixed to the blade disk 20a by welding at the fixing position 801.
- the second disk 80 is not limited to this, and may be fixed with a fastener such as a bolt or a screw or caulking.
