BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to harvesters, such as combines, and more particularly, to harvesters having a harvesting pretreatment unit connected to the front of the machine body and having a headlamp device.

A conventional harvester having a headlamp device is disclosed in, for example, Japanese Utility Model Publication No. 63-23143 (pages 2 to 5, see FIGS. 1 to 3), and Japanese Patent Application Laid-open No. Hei 10-136758 (paragraph [0015] , Paragraph [0024], see FIG. 6).

Any harvesting headlight device is intended only to illuminate the front of the machine body and is useful for securing a clock for planted stems of rows to be harvested while going straight on at night. However, there is room for improvement in terms of enabling easy and accurate positioning of the adjacent rows, for example when turning the machine body at the thermal end to transition from harvested rows to unharvested adjacent rows. There is.

The main object of the present invention is to improve this point and to provide a harvester which is easier to harvest at night or the like.

In order to achieve the above object, the harvester according to the present invention is a harvester having a harvesting pretreatment unit which is connected to the front part of the machine body and has a headlight device, and the headlight device is installed on the side of the harvesting pretreatment unit, and this harvesting pretreatment It is characterized by being comprised so that irradiation of the front and side of a part is possible.

According to this configuration, since the front of the harvesting pretreatment unit is irradiated by the headlamp device, the front view is secured well at night during the harvesting operation. In addition, since the side of the harvesting pretreatment unit is also irradiated by the headlamp device, the alignment of adjacent rows is easier and more accurate even when turning at night or the like. Therefore, it becomes unnecessary to retry turning frequently by repeatedly moving the main body forward and backward for the alignment.

In one suitable embodiment, the said harvest pretreatment part is comprised so that rocking is possible between a descending work state and a rising non-working state about the horizontal axis core behind it, and the several precipitation tools which act on the stem planted in the front of this harvest pretreatment part ( When the harvesting pretreatment part is in the descending working state, the headlight device irradiates the grasshopper on the outermost side and the ground on the transverse outward side and front than the grasshopper, When the pretreatment unit is in the rising non-working state, the front lamp unit is configured to irradiate the ground in front than when the headlamp device is in the lowering work state. This configuration is advantageous in the following points.

For example, the support arm 2 of the headlight (equivalent to the headlight device) 1 in the harvester disclosed in Japanese Utility Model Laid-Open No. 63-23143 discloses a cutting section A. It is pivotally attached about the support point 02 with respect to the side cover 13. The harvester also connects a support spring (2) connected to the support arm (2), a support (10) pivotally pivoting the harvesting section (A) about the rotation support point (01), and a support arm (2). The wire 4 is provided. According to this structure, even if the harvesting | reaping part A is raised or lowered, the direction of the headlight 1 is not changed by the action of the wire 4 and the tension spring 14, either. In such a configuration, when the harvest pretreatment unit is lifted up in the non-working state, the harvesting pretreatment unit is upward than at the time of operation, so the headlamp device is also upward. As a result, the front ground cannot be irradiated, making it difficult to carry out traveling at night. For this reason, in order to make a ground image irradiate even if a harvest pretreatment part is raised, a complicated headlight mowing structure is needed, and the direction control mechanism of a headlight device is needed.

In contrast, in the configuration of the present invention, when the harvesting pretreatment unit is lowered to the descending working state, the headlight device irradiates the grass dividing sphere, its transverse outer side, and the ground on the front. When the harvest pretreatment portion is raised to the rising non-working state, the headlamp device irradiates the ground where the harvest pretreatment portion is moved forward than the descending work state. Therefore, the simple attachment structure as long as the headlight device can be rocked with respect to the pre-harvest harvesting part makes it easier to see the grass dividing sphere and the ground on the side and the front of the work, even when the work is straight and the turn is turned. In addition, at the time of movement, the ground of the movement destination becomes easy to see.

Therefore, the attachment structure of the headlamp device becomes simpler, and a structure special for adjusting the irradiation direction becomes unnecessary, which is advantageous in terms of cost. Moreover, since the desired direction adjustment is performed in conjunction with the lifting operation of the harvesting pretreatment unit, even if the working vehicle is not conscious of only adjusting the irradiation direction of the headlamp apparatus, it is advantageous in terms of operation.

In addition, if the headlight device includes a first headlight and a second headlight having a lower irradiation direction than the first headlight, illumination required for work or movement as compared with the case where the headlight device comprises a single headlight is performed. The range is brighter throughout the lighting range. Therefore, the state of the minute grass, the side, and the front of it are easy to see, and work and movement are more easily performed.

At that time, if the first headlamp is arranged above the second headlamp, the installation space in the machine main body transverse direction required for the installation of the first and second headlamps is small, while both the headlamps are arranged in the machine main body transverse direction. Lose. In addition, if the second headlight having a downward irradiation direction is disposed above the first headlight, the second headlight will be difficult to irradiate with the second headlight unless the second headlight protrudes forward than the first headlight. From the side, the front face is forced to be an uneven surface. On the other hand, in the structure of this invention, a front surface of a headlamp apparatus can be made into a substantially flat surface from the side of a machine main body.

Therefore, the headlight device can be made compact in the transverse direction and simple in the front face side.

On the other hand, if the headlight device is configured to be switchable between an equalized state in which the first headlight and the second headlight are turned on, and an equalization state in which the first headlight is turned off and the second headlight is turned on, It is advantageous in terms of. That is, when the harvesting pretreatment part is in the ascending non-working state, the first headlight and the second headlight are also upward as compared with the case where the harvesting pretreatment part is in the descending work state, so that the opposite vehicle can be easily examined. At this time, when switching to the unbalanced state, the first headlight higher than the second headlight is turned off, and the second headlight is turned on. Therefore, when moving, it is possible to illuminate the front while avoiding irradiation of the opposing vehicle by the first headlamp by considering switching to the equalized state so as not to irradiate the opposing vehicle strongly.

In one suitable embodiment, the standing device of the stem planted behind the said plurality of grass dividing spheres is provided, and this standing device is provided with the horizontal cover which covers the transverse side of the said harvesting preprocessing part, and also the reflector and lens of the said headlamp apparatus. Is provided in the side cover, and the irradiation range of the headlamp apparatus is set by this reflector or lens. This configuration is advantageous in the following points.

For example, in the harvesting machine disclosed in JP-A-10-136758, the dustproof cover 3 covering the grain stem conveying part 2 upper part of the harvesting | reaping apparatus 1 (equivalent to the harvesting preprocessing part) Is divided into a front cover 4 and a rear cover 5, and the front cover 4 is fixed, and a headlamp (equivalent to the headlight device) 33 is attached to the front end of the front cover 4 at the same time. When the rear cover 5 is slid to the open position on the front side, the rear cover 5 covers the upper part of the headlamp 33, and the headlamp 33 is in addition to the normal forward irradiation area. The vicinity of the dividing port 25 is irradiated by the irradiation area reflected from the inner surface of the cover 5.

In the above prior art, it is necessary to provide an excellent reflector function in the rear cover in order to ensure that the dividing sphere is well illuminated, and the cost tends to increase from the production surface or the like. In addition, since the rear cover is brought into the open position when the dividing sphere is illuminated, there is also a problem that the dust-proofing action by the dustproof cover is lowered.

On the other hand, in the structure of this invention, a headlight apparatus is provided in the side cover connected to a standing device, and the irradiation range of the headlight apparatus which illuminates the front end part of a branching port and the front of a branching port is set by the reflector or lens of a headlight device. . Therefore, it is possible to illuminate the front end portion of the dichotomous sphere and the side and the front of the dichotomous bulb simply by turning on the headlight device having the reflector or the lens. Therefore, the field of view of the front becomes bright even at night, and the alignment of the grass in the grass field becomes easier. Moreover, since desired irradiation is ensured only by turning on a headlight apparatus, there are no obstacles, such as dust scattering like the said prior art. Further, since the reflector or lens is provided only in the headlamp device, the configuration can be obtained at low cost.

In addition, when the recess is provided in the lateral cover, and the headlamp device is assembled to the recess, projection to the outside of the headlamp device is suppressed, so that the headlamp device is less likely to be damaged. At that time, if the headlight devices are provided at both corners of the front part of the harvesting pretreatment unit so that the recesses open in the front and transverse outward directions, the respective headlight devices are not only in front of the harvest pretreatment unit but also in the vicinity of the transverse outward side. The configuration can be achieved more simply.

Moreover, even if the said transverse cover is provided above the outermost grass dividing port, the structure for illuminating the vicinity of a transverse outer side besides the front of a harvesting preprocessing part can be achieved more simply.

Other features and advantages will become apparent by reading the following description with reference to the accompanying drawings.

In addition, in the following description, the front-back direction, the front side, the back surface, the left-right direction, the horizontal direction, the horizontal side surface, and the up-down direction based on the machine body advance direction are respectively referred to as "front-back direction", "front", "rear", "left-right direction And "lateral direction", "lateral side surface" and "up and down direction".

That is, even when the harvesting pretreatment unit 10 is lowered in the lowering work state, even when the harvesting pretreatment unit 10 is lowered in the ascending working state, the irradiation range by the lower headlight 23 is located behind the irradiation range by the upper headlight 22. It is set to be located.

As shown in Fig. 8, the side lamps 40 are disposed in the side lamp assembly recesses 34 provided with through holes in the side plate portions 32 of the side cover 30. The reflector 41 fixed to the lateral cover 30, the valve 42 supported by the reflector 41, and the lens 43 fixed to the front part of the reflector 41 are comprised.

2 shows the irradiation range S by the side lamp 40 and the irradiation range RD, which is viewed from the plane irradiated by the left and right headlamp apparatus 20 when the harvesting pretreatment unit 10 is lowered in the lowering work state. LD). Fig. 6A shows the irradiation range in terms of the irradiation of the left and right headlamp devices 20 when the harvesting pretreatment unit 10 is lowered in the lowering work state. FIG. 6B shows the irradiation range in terms of the irradiation of the left and right headlight apparatuses 20 when the harvesting pretreatment unit 10 rises to the rising non-working state that rises to the stroke end.

When carrying out a harvesting operation, it is necessary to lower the harvesting pretreatment unit 10 to the descending working state. This point and this invention are advantageous at the point which the irradiation range required for the night harvesting operation is correctly ensured. That is, by the upper headlight 22 and the lower headlight 23 of the left headlight device 20, the front end portion of the leftmost transverse outer dichroic sphere 12 and the left transverse outer side and the front of the dichroic sphere 12 are located. An irradiation range (LD) for irradiating on the ground is secured. In addition, by the upper headlight 22 and the lower headlight 23 of the right headlight device 20, the front end portion of the rightmost transverse outer side dividing port 12 and the right side outward side and the front side of this branching port 12 The irradiation range RD for irradiating on the ground is also secured.

At this time, the pre-treatment unit is processed by the illumination of the illumination range S by the side lamp 40 together with the illumination in the lateral outward direction by the upper headlight 22 or the lower headlight 23 of the left headlight device 20. Since the harvesting grain stem is illuminated in the vicinity of the cross section of (10), it is especially easy to align the grass dividing sphere 12 with respect to the uncut grain stem by illuminating the vicinity of the stem base of an uncut grain stem.

In addition, the present invention is advantageous in that the traveling range required for night driving is precisely secured by raising the harvesting pretreatment unit 10 to the raised non-working state in which the cutting pretreatment unit 10 is raised to the stroke end when traveling in a non-working state such as road running. That is, by the upper head 22 and the lower head 23 of the headlamp apparatus 20 on the left side, the irradiation range LU for irradiating the ground on the ground away from the main body of the machine than the irradiation range LD is ensured. . Moreover, the irradiation range RU which irradiates the ground image which moved further away from the main body of the machine than the said irradiation range RD is also ensured by the upper headlight 22 and the lower headlight 23 of the right headlight apparatus 20. At this time, the upward reflection by the upward reflection tongue 25d prevents the driver of the opposite vehicle from dazzling.

As shown in FIG. 5, in each headlight device 20, the upper headlight 22 and the lower headlight 23 also retreat to the rear side than the front surface 13c of the standing case 13b of the stem standing device 13. Retreat by the difference (B) is located. In order to make such a recessed difference B, when the headlight device 20 is assembled and attached to the headlight device assembly recess 33, the outer surface of the lens 21 of both headlights 22 and 23 is a standing case. It is comprised so that it may retreat slightly rather than the front surface 13c of 13b. Thus, when the forced dividing device 50 is mounted on the front side of the stem standing device 13 positioned at the transverse end, as shown by the double-dotted line in Figs. 4 and 5, the headlamp device 20 is obstructed. It is hard to make, and the forced dividing apparatus 50 approaches the inclined front surface 13c of the dividing case 13b of the stem standing apparatus 13, and is easy to follow.
