Description

  The present invention relates to a combine that performs a mowing operation, and more specifically, a control unit and a threshing unit are provided on a machine body including a traveling device, and a mowing unit is provided in front of the control unit and the threshing unit so as to be movable up and down. The present invention relates to a combine that enables a night harvesting operation by illuminating the front of the section with a headlight or a work light.

  Combine harvesters that harvest rice and wheat and perform threshing and selection processing usually perform harvesting work during the daylighted by natural lighting. However, considering the degree of work progress and the work schedule for the following day, etc., there are cases where cutting is continued even after twilight or after sunset, in which case the front of the cutting part is artificially illuminated. It is necessary to perform cutting and traveling in the field. In view of this, a headlamp used when traveling on the road and a working lamp that illuminates the area around the divider of the reaping section are provided, and these are turned on to provide a lighting device for twilight or nighttime work.

  These lighting devices are constituted by a front panel provided at the front part of the control part, a side cover provided at the cutting part, a top cover or a dust-proof cover, a tip of the discharge auger, or a work lamp provided at the front upper part of the cabin. (For example, see Patent Documents 1 to 5). It is also known to provide a work lamp on the back side of the operation panel of the control unit (see Patent Document 6).

  As mentioned above, combines use the headlights and work lights to illuminate the front side of the aircraft as lighting equipment during twilight and nighttime work, but existing lighting is required for users who want more comfortable workability and safety. There is a demand for more sufficient brightness, which is not satisfactory with the device. Therefore, in order to respond to such a voice, the manufacturer side needs to prepare a brighter illumination device as an option.

  In addition, when preparing an optional lighting device, if you try to develop a new lighting device without using the standard lighting device at all, you will be forced to increase costs due to new design costs, parts management costs, etc. The Furthermore, if an attempt is made to change the illumination device provided as a standard to an optional illumination device later, a recombination work of the illumination device is generated, and the cost is inevitably increased here.

  Therefore, if a new work light is added while leaving the standard lighting device, a brighter lighting device in addition to the standard device can be provided as an option at a relatively low cost, and the lighting device can be retrofitted. Will also be easier. However, in this case, it is not necessary to attach work lights everywhere, and it is possible to effectively illuminate the places that really need illumination in the cutting operation with as few work lights as possible. desirable.

  On the other hand, the divider provided in the cutting part divides the napped cereals left and right, and the cerealed cereals are caused by the pulling device and conveyed toward the threshing unit by the conveying device. However, if the dividing operation is performed in such a way that the divider interrupts the cereal stock, the reaping action of the cereal is disturbed and the conveyance is disturbed. This may cause clogging of the conveying device and the threshing unit. Also, if the cedar is harvested with the dividers at both ends in the left-right direction being split, there is a risk that the grain will be crushed and the cuts will be worsened or left behind. It is desirable to steer the aircraft appropriately.

  For that purpose, it is first required to be able to check the weeding state of the divider, and it is important to brightly illuminate the periphery of the divider even in the night cutting operation. Therefore, when an illumination device is provided as an option, it is effective to add work lights that can illuminate the dividers at both ends in the left-right direction. However, if the work light is provided on the cutting part side as before and the surroundings of the divider are illuminated, the area around the divider can be surely always illuminated. There is a problem that the visibility of the bag is deteriorated.

  Therefore, in view of the above-described problems, the present invention improves the visibility of the cocoon during the harvesting operation in a combine that enables the harvesting operation at night by illuminating the front of the cutting unit with a headlight or a work light. It is an object of the present invention to provide a combine that can illuminate the periphery of the divider of the harvesting unit using a work lamp while keeping it, and can reduce the installation cost of the work lamp as much as possible.

  In order to solve the above-mentioned problem, the present invention firstly provides a control unit and a threshing unit in an aircraft equipped with a traveling device, and a reaping unit is provided in front of the control unit and the threshing unit so as to be movable up and down. In a combine that enables the harvesting work at night by illuminating the front with a headlight or work light, the work light that irradiates the periphery of the divider of the harvesting part is provided in the control part. The structure is characterized by irradiating the periphery of the divider across the left and right ends of the reaping portion that has been configured and lowered, and attaching a work lamp to a location that is removed from the line of sight when the divider is viewed from the control portion.

  According to the present invention, secondly, the work lamp is attached to a location where the light source is not blocked by the raised cutting portion. Furthermore, the present invention is characterized in that, thirdly, a support frame for supporting an operator is installed horizontally above an operation box standing on the front part of the control unit, and a work lamp is attached to the support frame. To do. And fourthly, the present invention attaches a base bracket across the front side which is the left and right direction of the support frame and the rear side which is bent backward from the end of the front side. It is characterized by attaching a work light to the support frame.

  According to the combine of the present invention, the working lamp that irradiates the periphery of the divider of the cutting part is provided in the control part. Since the work light is attached to the part that is removed from the line of sight when the divider is viewed from the control unit, the work light is lit to light up the area around the divider during dusk and at night. Therefore, it is possible to efficiently perform the cutting operation without causing clogging of the conveying device and the threshing portion by preventing the dividing by the divider as much as possible and preventing the turbulent conveyance of the cereal and the uncut portion.

  In addition, when the work light is provided on the front panel provided in the front part of the control unit, the distance from the front panel, for example, the area around the divider on the left end side is blocked by the napped grains, and it is illuminated from the light distribution characteristics of the work light. I can't. However, it is possible to irradiate the periphery of the divider across the left and right ends of the cutting part without being interrupted by the napped grain cereal.For example, if a work light is installed at a position higher than the front panel, the work light may not be a plurality of lamps. A single lamp can be used, and the cost of the work lamp can be reduced.

  Furthermore, if the work lamp is provided as close to the divider as possible, the area around the divider can be brightly illuminated. Therefore, like the work lamp described in Patent Document 6, the probability of providing the work lamp on the line of sight of viewing the harvesting part from the control part is increased. However, if the installation position of the work light is selected on condition that it is as far as possible from the line of sight when the divider is viewed from the control section, the reflected light from the periphery of the divider across the left and right ends is not blocked by the work light itself. Therefore, it is possible to improve the visibility around the divider.

  And when the work light is provided in the control part, when the mowing part is raised, the light source of the work light is often blocked by the mowing part, but here the light source is not obstructed by the mowing part that raised the work light. If attached, the work light provided on the control unit can illuminate the lower part of the divider even if the harvesting part is raised during the cutting operation at the edge of the wing, so that the cutting work avoids the collision of the divider with the ridge. Can be performed accurately.

  In addition, when a support frame that supports the worker is installed horizontally above the operation box that stands on the front of the control unit, and a work light is attached to this support frame, the support frame that is equipped with the standard combine The working light can be easily attached using the same as it is, and a new attachment frame or the like is not required, leading to cost reduction. Further, it is possible to easily attach the work lamp later.

  Furthermore, when attaching the base bracket across the front side that is the left and right direction of the support frame and the rear side that is bent backward from the end of the front side, and attaching the work light to the support frame via this base bracket, Even when the support frame is composed of a circular pipe, the work lamp does not rotate unexpectedly around the center of the pipe, so that the irradiation direction of the work lamp can be stabilized and brightly illuminate the necessary parts in the cutting operation. .

  Further, the threshing section C, the harvesting section D, and the waste disposal apparatus E are provided with a direction indicator (vehicle width lamp), a direction indicator / tail lamp / brake lamp, a back lamp, and a work lamp. That is, the left direction indicator 47 is provided on the side surface of the cylinder cover 9 of the threshing portion, and the left and right direction indicators / tail lights / brake lights 48 and the back lamp 49 are provided on the rear side of the waste disposal apparatus E and the grain collection portion D. A work lamp 50 is provided to illuminate the rear side of the aircraft. In addition, a work lamp 51 for illuminating the grain discharge position is provided in the vicinity of the grain discharge port 13a of the discharge auger 13, and when the discharge auger 13 is stored on the machine body 3, the work lamp 51 is a leftmost divider. 4 The surrounding area can be illuminated.

  The lighting device and the like described above are equipped in a standard combine. However, the work lamp described below is an illumination device provided as an option, and is provided in the control unit A that is a feature of the present invention. It is a work light to be provided. That is, this work lamp is configured using a high intensity discharged lamp 52 as one lamp provided in the control unit A as shown in FIGS.

  More specifically, the high-intensity discharge lamp 52 includes a discharge valve 52b serving as a ballast, a reflector, and a light source in a housing 52a that constitutes a main body of the work lamp, and includes a lens 52c on the front surface. The high-intensity discharge lamp 52 is attached to the upper left side of the front side 21b of the support frame 21 of the control unit A, and irradiates the periphery of the divider 4 across the left and right ends of the lowered cutting unit B at a time.

  Further, when viewing the divider 4 on the right end side from the control section A, the high-intensity discharge lamp 52 can be seen from the operator's line of sight, whether it is sitting in the driver's seat 23 or standing up so that it is difficult to see. Since the reflected light from the periphery of the divider 4 reaches the worker without being blocked by the high-intensity discharge lamp 52, the visibility of the periphery of the divider 4 is not hindered.

  Furthermore, when the divider 4 on the left end side is visually observed from the control section A, the high-intensity discharge lamp 52 can be used by the operator regardless of whether it is sitting in the driver's seat 23 or standing up so that it is difficult to see. Since the reflected light from the periphery of the divider 4 reaches the operator without being blocked by the high-intensity discharge lamp 52, the visual recognition of the periphery of the divider 4 is not hindered.

  Moreover, even when the reaping part B is raised to the maximum, the high-intensity discharge lamp 52 is positioned higher than the top cover 41 of the reaping part B and the light source is blocked by the mounting parts of these reaping parts B. Since the front side of the cutting part B is illuminated as it is, the high-intensity discharge lamp 52 illuminates the hook below the divider 4 even when the cutting part B is raised during the cutting operation at the edge of the cutting, and It is possible to avoid the collision with the machine and to perform the mowing work accurately.

  And when attaching the high-intensity discharge lamp 52 to the support frame 21 of the control part A, the base bracket 53 comprised of an L-shaped plate as shown in FIG. A saddle band 54 is attached to two locations 21b and one rear side 21c bent backward from the end of the front side 21b, and a U-shaped bracket is attached to the top of the base bracket 53 on the front side 21b side. A high-intensity discharge lamp 52 is attached through 55 so that the irradiation angle in the vertical direction can be adjusted somewhat.

  For this reason, even if the support frame 21 is made of a circular pipe material in consideration of the ease of gripping by the operator, the base bracket 53 is attached by using the front side 21b and the rear side 21c that are substantially orthogonal to each other. Further, it is possible to prevent the pipe 21 from pivoting and moving in the longitudinal direction. Therefore, the irradiation direction of the high-intensity discharge lamp 52 attached thereto is always constant, so that the necessary illumination location can be illuminated with certainty.

  Note that a seal 56 made of sponge or the like is wound around the support frame 21 to which the saddle band 54 is attached in advance to improve the adhesion between the saddle band 54 and the support frame 21, and the body vibration is buffered to increase the brightness. The discharge lamp 52 is protected. Further, the lead wire 52 d drawn from the high-intensity discharge lamp 52 is fixed to the support frame 21 with a wire band 57 and arranged.

  Although the embodiment of the present invention has been described above, the high-intensity discharge lamp 52 described above operates the combination switch 27 and is lit together with the headlight and other work lights at dusk or at night, so that it is easy to attract insects. However, the use of a UV-cut type high-intensity discharge lamp that cuts off the ultraviolet light preferred by insects can greatly reduce insect attraction. In addition, for example, a high-intensity LED lamp may be used in place of the high-intensity discharge lamp, and other standard illumination devices may be replaced with incandescent bulbs or halogen lamps as low-power consumption LED lamps. The present invention is not limited to the above embodiment.
