Further, the left direction of the work machine 10 is indicated by a symbol LH, and the right direction is indicated by RH.

  As shown in FIG. 1, a work machine 10 includes a power source 12, a traveling device 13, a snow removal working unit 14, and an operation panel 15 (also referred to as an operation device), in a machine body 11 corresponding to a main body (body frame) of the work machine 10. Is a self-propelled snowplow (also referred to as a walking snowplow). The snow removal working unit 14 is disposed at the front of the machine body 11 and includes an auger housing 41, a shooter 45, and the like, which will be described later.

  The operation panel 15 has operators such as various switches, levers, buttons and the like for operating the work machine 10. For example, the operation panel 15 includes a switch for switching on / off of the headlamp 20.

  An operation handle 16 extends from the rear part of the body 11 to the upper rear part. A worker (also referred to as a driver or a driver) who performs snow removal work holds the operation handle 16 behind the work machine 10 (RR side), and steers the work machine 10 while walking with the work machine 10. . In the figure, the traveling direction of the work machine 10 is indicated by a symbol Fr, and the direction opposite to the traveling direction Fr is indicated by a symbol Rr.

  The power source 12 is provided at substantially the center in the front-rear direction of the work machine 10, and a pair of arms 17 are erected from the front upper portion of the power source 12 with a space left and right. A headlamp 20 (illuminating unit) that irradiates illumination light is supported on the upper ends of these arms 17.

  The power source 12 drives the traveling device 13 and the snow removal working unit 14, and includes an electric motor and an engine (not shown). The electric motor drives the traveling device 13 under the control of a control unit (not shown) that controls the work machine 10. In this configuration, the work machine 10 includes a crawler-type traveling device 13 that is spaced from side to side, and each traveling device 13 is driven by a different electric motor via a speed reduction mechanism.

  The engine is an internal combustion engine, and drives the snow removal working unit 14 via a transmission (not shown) under the control of the control unit. A generator (not shown) is provided on the drive shaft of the engine. The electric power generated by the generator is supplied to the electrical components included in the work machine 10. Specifically, the electrical components are the headlamp 20, a battery (not shown), an electric motor (not shown), and the like. The traveling device 13 may be driven by an engine.

As shown in FIG. 1, the snow removal working unit 14 includes an auger housing 41, a blower housing 42 connected to the rear part of the auger housing 41, an auger 43 provided in the auger housing 41, and a blower housing 42. A blower (not shown), and a shooter 45 extending upward from the blower housing 42.
The auger housing 41 is a cover that covers the upper, rear, and left and right sides of the auger 43, and covers the auger 43 with the front and lower sides of the auger 43 exposed.

  The auger 43 is rotationally driven by the transmission and scrapes off the snow in front of the work machine 10. Under the control of the control unit, the blower supplies the snow scraped off by the auger 43 to the shooter 45, and the shooter 45 causes the snow to fly away. That is, the shooter 45 functions as a snow throwing unit that throws snow collected by the auger 43 to a position away from the work machine 10.

  The shooter 45 is provided so as to be rotatable around an axis extending in the vertical direction with respect to the installation surface Gr, and is rotated by a shooter drive motor (not shown). By rotating the shooter 45, the snow throwing direction can be adjusted to an arbitrary direction of front, rear, left and right.

A shooter guide 48 is provided at the upper end of the shooter 45. The shooter guide 48 is mounted so as to be swingable up and down, and the angle in the vertical direction (that is, the snow throwing angle) can be adjusted. The snow guide 48 has a snow throwing angle controlled by a guide drive motor (not shown).
The work machine 10 can travel forward by the left and right traveling devices 13, scrape snow by the front auger 43, and fly the scraped snow far away via the shooter 45 by the blower.

  The operation handle 16 has a grip 61 held by an operator and left and right turning operation levers 62. Further, the left operation handle 16 has a travel preparation lever 63.

In addition, when the operator holds the left or right turning operation lever 62, the operator can turn the working machine 10 toward the holding hand.

  The headlamp 20 includes a case 22, a cover 24 disposed on the front surface 22 </ b> A of the case 22, and an LED module 26 as a light source accommodated in the case 22. The case 22 is attached to the pair of arms 17 so that the front surface 22A faces frontward (FR direction). The headlamp 20 illuminates the front of the work machine 10 by irradiating light emitted from the LED module 26 from the cover 24.

  The position of the headlamp 20 is behind the snow removal working unit 14 and above the auger housing 41 (UP side). For this reason, the headlamp 20 irradiates illumination light from above and behind the snow removal working unit 14 toward a range including the snow removal working unit 14, preferably a range including the front of the auger housing 41.

  FIG. 2 is a perspective view of the headlamp 20. FIG. 3A is a front view of the headlamp 20, and FIG. 3B is a side view of the headlamp 20.

  The case 22 corresponds to the housing of the headlamp 20. The case 22 is made of, for example, a synthetic resin, is formed in a substantially box shape, and the inside is hollow. An opening 22B is formed on the front surface 22A of the case 22, and a slit 22E is formed on the side surface 22D. Case 22 has slit 22E in each of side 22D which appears in Drawing 2, and side 22D located in the side opposite to this side 22D. The opening 22B and the slit 22E penetrate the inside and outside of the case 22.

  The cover 24 is made of a light-transmitting material (for example, synthetic resin, glass, various crystals, etc.), and transmits light emitted from the LED module 26 in a state where the cover 24 is attached to the case 22. Radiates out. Although described in detail later, the cover 24 includes a cover front portion 24A that fits into the opening 22B, and a protrusion 24C (projection) that fits into the slit 22E.

  The opening 22B is a hole having an opening area that occupies most of the front surface 22A. When the cover 24 is attached to the case 22, the opening 22B is closed by the cover front portion 24A. The slit 22E is a long hole extending in the vertical direction. A protrusion 24C is fitted into the slit 22E from the inside of the case 22, and the slit 22E is closed by the protrusion 24C. Thus, since the opening 22B and the slit 22E are closed by attaching the cover 24, it is possible to prevent water and dust from entering.

  The headlamp 20 irradiates the illumination light transmitted through the cover front portion 24A from the front surface 22A and the illumination light transmitted through the protrusion 24C from the side surface 24D. For this reason, the front surface 22 </ b> A and the side surface 24 </ b> D can be referred to as the irradiation surface of the headlamp 20.

  There is almost no step between the surface of the cover front portion 24A and the peripheral edge portion of the opening 22B, and preferably it is flush. For this reason, the front surface 22A has a flat structure as a whole, and specifically, is a flat surface or a curved surface having no protrusions or irregularities. Further, in the two side surfaces 22D of the case 22, there is almost no step between the surface of the protrusion 24C and the peripheral edge portion of the slit 22E, and preferably they are flush. Each of the two side surfaces 22D has a flat and flat structure as a whole, and specifically, is a flat surface or a curved surface having no protrusions or irregularities.

3A and 3B, the vertical planes VP1 and VP2 are indicated by broken lines. The vertical planes VP1 and VP2 are, for example, virtual planes that are perpendicular to or close to the installation plane Gr (FIG. 1).
As shown in FIG. 3A, the side surface 22D is inclined with respect to the vertical surface VP1 so as to face downward (DN direction). Although the magnitude of the inclination (inclination angle) θ1 of the side surface 22D is arbitrary, for example, θ1 may be selected from a range of 15 ° to 20 °. Further, as shown in FIG. 3A, in the present embodiment, the inclination angle of the right side (RH side) side surface 22D with respect to the vertical plane VP1 is equal to the inclination angle of the left side (LH side) side surface 22D. Although illustrated, different angles may be used.
Further, the upper surface 22C and the bottom surface 22G of the case 22 are arbitrary, but are preferably flat surfaces, for example, flat surfaces.

  As shown in FIG. 3B, the front surface 22A is inclined so as to face downward with respect to the vertical surface VP2. Although the magnitude of the inclination (inclination angle) θ2 of the front surface 22A is arbitrary, for example, θ2 may be selected from a range of 15 ° to 20 °. Further, although the state and inclination of the back surface 22F of the case 22 are arbitrary, it is preferably a flat surface, and may be a surface parallel to the vertical surface VP2, for example, as shown in FIG.

4 is a diagram showing a configuration of the headlamp 20, FIG. 4A is a cross-sectional view of the main part taken along line AA of FIG. 3A, and FIG. 4B is FIG. It is principal part sectional drawing in the BB line of ().
The LED module 26 includes a substrate 28 and LEDs 30 mounted on the substrate 28. The LED 30 is a surface mount type (so-called chip type) element, and is lit by receiving power from a lighting circuit (not shown) mounted on the substrate 28 or another substrate. In the present embodiment, an example in which a plurality of LEDs 30 are arranged on the substrate 28 is shown, but the number of LEDs 30 is arbitrary. Further, as the LED 30, it is also possible to use a so-called bullet-type LED encapsulated in a light-transmitting resin. Further, the LED 30 may be used by being fixed to a bracket or the like other than the substrate 28, or a reflector may be provided around the LED 30.

  As shown in FIG. 4A, the LED module 26 is arranged behind the cover front portion 24A. More specifically, as shown in FIG. 4B, the position of the LED 30 is behind the slit 22E.

The cover front portion 24A is formed in a substantially plate shape along the front surface 22A of the case 22, and a pair of arm portions 24B is erected. The arm 24B is provided with a protrusion 24C.
The arm 24 </ b> B extends from the front cover 24 </ b> A to the rear side (RR side) with the cover 24 attached to the case 22. The protrusion 24C provided on the right arm 24B protrudes to the right, and the protrusion 24C provided on the left arm 24B protrudes to the left. That is, as shown in FIG. 4B, each of the pair of arm portions 24B includes protrusions 24C that protrude outward.

  The arm 24 </ b> B is inserted into the case 22 through the opening 22 </ b> B when the cover 24 is attached to the case 22. The pair of arm portions 24B are respectively inserted along the inner surface of the side surface 22D, and the projection 24C is fitted into the slit 22E from the inside of the case 22, whereby the attachment of the cover 24 is completed. In this state, the cover 24 is fixed to the case 22 by the protrusion 24C engaging with the slit 22E. As described above, the cover 24 can be attached to the case 22 by a simple operation, and the cover 24 can be fixed so as not to be detached by a simple configuration. A receiving portion 22 </ b> H is formed on the inner surface of the case 22. When attaching the cover 24 to the case 22, the position of the protrusion 24 </ b> C can be easily and reliably adjusted to the position of the slit 22 </ b> E by abutting against the receiving portion 22 </ b> H of the arm portion 24 </ b> B. By providing the receiving portion 22H, the effect of more reliably preventing the cover 24 from rattling can be expected.

  The emitted light of the LED 30 is emitted through the cover front part 24A, the arm part 24B, and the protrusion 24C. Here, the emitted light of the LED 30 is refracted downward when passing through the cover front portion 24A.

  As shown in FIG. 4A, the outer surface 24AF of the cover front portion 24A is a downward inclined surface corresponding to the front surface 22A. On the other hand, the inner surface 24AR of the cover front portion 24A is a surface parallel to the vertical surface VP2 (FIG. 3B), for example. That is, the cover front portion 24A is configured to have a trapezoidal cross-sectional shape, and the outer surface 24AF is inclined relatively downward with respect to the inner surface 24AR. In the drawing, the inner surface 24AR is shown as a surface parallel to the vertical surface VP2 (FIG. 3B). However, the present invention is not limited to this configuration. If the outer surface 24AF is inclined with respect to the inner surface 24AR, the angle of the inner surface 24AR is arbitrary. is there.

  The cover front portion 24A is configured such that the outer surface 24AF, which is an emission surface positioned on the outer side, is inclined downward with respect to the inner surface 24AR, which is an incident surface positioned on the LED 30 side, so that the LED 30 enters the cover front portion 24A. Light is refracted downward. For example, as indicated by a symbol L2 in FIG. 4A, the emitted light in the front direction of the LED 30 is refracted downward when passing through the cover front portion 24A. Further, as indicated by the symbol L3, the downward emitted light of the LED 30 is refracted further downward when passing through the cover front portion 24A. Further, as indicated by reference numeral L1, upward light emitted from the LED 30 is refracted downward when transmitted through the cover front portion 24A, and is emitted in the front direction or obliquely downward. Thus, since cover front part 24A refracts the light of LED30 downward, the emitted light of LED30 is collected and emitted as a whole downward.

  4B, a part of the light emitted by the LED 30 enters the arm portion 24B, passes through the protrusion 24C, and is directed from the slit 22E toward the side of the headlamp 20. Radiated as illumination light. Here, similarly to the cover front portion 24A, the cross-sectional shapes of the arm portion 24B and the protrusion 24C may be trapezoidal, and the radiated light emitted from the slit 22E may be refracted downward. In this case, the emitted light of the LED 30 is refracted downward when passing through the arm portion 24B and the protrusion 24C, and illumination light can be irradiated downward from the side surface 24D.

  According to this configuration, the headlamp 20 can irradiate illumination light downward from the front surface 22A. It is also possible to adopt a configuration in which illumination light is irradiated downward from the side surface 22D. Therefore, the structure which can irradiate downward light to the different direction (front and side of the headlamp 20) from the headlamp 20 is easily realizable.

Moreover, the effect which diffuses the emitted light of LED30 to the left-right direction can be anticipated by making the outer surface 24AF of cover front part 24A into the surface curved in the left-right direction.
Specifically, as shown in FIG. 4B, the outer surface 24AF is a curved surface so that the end 24AS is located behind the central portion 24AC in the left-right direction. In this case, the front surface 22A of the case 22 is preferably curved similarly to the outer surface 24AF. Further, the inner surface 24AR can be a flat surface having no curvature, for example, but it is sufficient that the inner surface 24AR and the outer surface 24AF have an inclination at least at the end 24AS of the cover front portion 24A.

  For example, as indicated by a symbol L11, the light emitted from the LED 30 toward the central portion 24AC of the cover front portion 24A is radiated in the straight traveling direction. On the other hand, as indicated by reference numeral L12, the light emitted from the LED 30 toward the left and right end portions 24AS is refracted and emitted so as to spread in the left-right direction. With this configuration, it is possible to illuminate a wider area by diffusing illumination light in the left-right direction of the work machine 10.

  As shown in FIGS. 4A and 4B, the effect of refracting light by the cover front portion 24A may be refracted by, for example, cutting the inner surface 24AR.

In the headlamp 20, since the front surface 22A including the cover front portion 24A (outer surface 24AF) is inclined downward, even if snow adheres to the cover front portion 24A, the snow is likely to fall off due to its own weight. Furthermore, since the upper end of the front surface 22A protrudes forward and functions as a kite, the snow rolled up by snowfall or snow removal work is blocked by the kite, and snow cover on the cover front portion 24A can be suppressed or prevented. Further, since the entire front surface 22A including the cover front portion 24A is inclined downward, it is possible to suppress snow accumulation at the peripheral edge portion of the cover front portion 24A. Furthermore, since the entire front surface 22A including the cover front portion 24A is configured by a flat surface having no protrusions or irregularities, snow on the surface can be more effectively suppressed.
Therefore, the state where the illumination light from the front surface 22A of the case 22 is blocked by snowfall can be effectively suppressed or avoided.

  Further, the case 22 has a slit 22E that opens to the side surface 22D, and can emit illumination light through the slit 22E. The side surface 22D of the case 22 constitutes a surface having a downward slope together with the surface of the protrusion 24C fitted into the slit 22E. For this reason, similarly to the front surface 22A, it is possible to effectively suppress snow on the side surface 22D, and it is possible to suppress or avoid a state in which the illumination light from the slit 22E is blocked by the snow.

  With this configuration, it is possible to avoid a state in which the illumination light of the headlamp 20 is dimmed due to snowfall during snowfall or snow removal work, and the sides of the snow removal work unit 14 and the body 11 are illuminated with sufficient brightness. can do. Further, since work such as removing snow from the headlamp 20 is not required, work efficiency can be improved.

  In general, among the light sources used as illumination for work equipment, lamps such as halogen lamps generate a large amount of heat, whereas solid light sources such as LEDs 30 and discharge tube light sources such as HID have a low amount of heat generation. It has been. When lamps are used as the light source for work equipment used in snowfall environments, the snow melting effect due to the heat generated by the light source can be expected, but when using a solid light source or discharge tube light source, it is difficult to expect the snow melting effect. It is desirable to take measures against snow. Since the headlamp 20 of this embodiment can suppress a decrease in the amount of light due to snowfall regardless of the type of light source, there is no restriction on the type of light source employed in the headlamp 20. For this reason, for example, power consumption can be reduced by adopting a solid light source or a discharge tube light source.

FIG. 5 is a plan view of the work machine 10, and FIG. 6 is a perspective view of the work machine 10.
In these FIG.5 and FIG.6, the illumination light which the headlamp 20 radiates | emits is shown by the arrow.
The headlamp 20 is disposed above and behind the snow removal working unit 14, is disposed so as to face the front of the work machine 10, and irradiates illumination light toward the traveling direction (Fr) of the work machine 10. The field of view in the range including the snow removal working unit 14 can be kept good. Further, as described with reference to FIG. 4B, since the illumination light of the headlamp 20 is diffused and irradiated in the left-right direction, the snow throwing direction by the shooter 45 can also be illuminated, and a wider field of view. Can be secured.

  As shown in FIG. 5, the headlamp 20 is located at a position shifted from the shooter 45 in the left-right direction of the body 11. For this reason, the range in which the illumination light of the headlamp 20 is blocked by the shooter 45 is small, and the illumination light can be effectively irradiated avoiding the shooter 45.

  Further, the headlamp 20 is in a position overlapping the traveling device 13 in the front-rear direction of the work machine 10. In other words, the traveling device 13 is located on the left and right of the headlamp 20. For this reason, the range including the side of the traveling apparatus 13 is illuminated by the illumination light which the headlamp 20 radiates | emits from the slit 22E. Thereby, since the visibility of the side of the traveling device 13 can be improved, it can be expected that, for example, the worker can easily check the safety when the work machine 10 is traveling or turning. Therefore, the maneuverability and workability of the work machine 10 can be improved. Moreover, the effect which alert | reports that the working machine 10 is in operation | movement to the pedestrian etc. around the working machine 10 with the illumination light from the slit 22E can be expected.

As described above, in the present embodiment, the working machine 10 including the headlamp 20 has been described. The headlamp 20 includes an LED module 26, a case 22 that houses the LED module 26, and a translucent cover 24 disposed on one surface of the case 22, and the cover 24 is disposed in the case 22. The front surface 22A is a flat surface that is inclined downward.
According to this configuration, snow on the cover 24 of the headlamp 20 can be suppressed, and a state where illumination light is blocked by the snow can be avoided. For this reason, it is possible to realize the work machine 10 as a snow removal machine in which the illumination light is not easily blocked by snowfall on the headlamp 20. As a result, when the work machine 10 is traveling and when the work machine 10 is working, the worker's field of view can be kept good, and workability can be improved.

The cover 24 refracts and emits light incident from the LED module 26 side downward.
According to this configuration, the light emitted from the LED module 26 can be refracted and irradiated downward by the cover 24. For this reason, it is possible to effectively illuminate the work implement 10 with the center below the headlamp 20.

The cover 24 is disposed on the front surface 22A of the case 22, and a slit 22E that emits light emitted from the LED module 26 is provided on a side surface 22D of the case 22.
According to this structure, light can be irradiated from the opening 22B (cover front part 24A) of the front surface 22A and the slit 22E provided in the side surface 22D. Thereby, light can be emitted from the headlamp 20 in a plurality of directions, and a wide range around the work implement 10 can be illuminated.

  The cover 24 includes a protrusion 24 </ b> C inserted into the case 22, and the protrusion 24 </ b> C is fitted into the slit 22 </ b> E from the inside of the case 22 to fix the cover 24 to the case 22. Thereby, the cover 24 can be fixed to the case 22 with a simple configuration.

  Further, the side surface 22D on which the slit 22E is formed is a flat surface that is inclined downward. As a result, it is possible to suppress snow on the side surface 22D, and it is possible to avoid a state in which the illumination light irradiated from the slit 22E is blocked by snow.

  In addition, the work machine 10 includes a snow removal working unit 14 at the front of the machine body 11, and the headlamp 20 illuminates a range including the snow removal working unit 14. Thereby, the visibility of the range including the snow removal operation | work part 14 can be improved.

The above embodiment is merely an embodiment of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.
For example, the cover 24 only needs to have translucency, and may be colorless and transparent or colored such as yellow or white. The light source of the headlamp 20 is not limited to a solid light source or a discharge tube light source, and a halogen lamp or a light bulb may be used. In this case, the case 22 may be made of metal in response to a high heat radiation amount from these light sources.

Moreover, there is no restriction | limiting about the color and wavelength of the light which the headlamp 20 emits, For example, it is good also as a structure which emits the yellow light suitable for during snowfall. Further, the illumination light emitted from the front face 20A from the front face 22A and the illumination light emitted from the slit 22E may be light of different colors. In order to change the color of the illumination light to an arbitrary color, the color of the illumination light may be changed by the cover 24, or the color of light emitted from a light source such as the LED module 26 may be changed.
