Description

The present invention relates to an agricultural work machine.

Overseas, including Europe, tractors are already allowed to drive on public roads with tow-type agricultural work machines installed. It is a requirement to attach lighting equipment such as right turn signal (right turn signal) and side light (positioning lamp). In Europe, the power connector of the lamp is a DIN standard connector (national standard 72577 of the Federal Republic of Germany) (hereinafter referred to as "DIN standard connector") as shown in Fig. 1. Each light is attached to the tractor. A DIN standard connector is attached so that the device lights up in conjunction with operations such as braking. The DIN standard connector (female) on the tractor side and the wire harness of the lamp provided on the agricultural work machine side. By connecting to the DIN standard connector (male) attached to the side end, the power supply wiring of each lighting device on the tractor side is connected one-to-one with the lighting device on the farming machine side. When removing, the wiring related to the lamp can be easily separated by simply removing the DIN standard connector.

In Japan, as described in Non-Patent Document 1 below, JFMMAS (Nippon Agricultural Co., Ltd.) CN8-pole connector has been used as a power supply wiring connector for lighting equipment in recent years. FIG. 2 is a diagram showing a CN8-pole M connector (male connector) and a CN8-pole F connector (female connector) of the Nichino Kogyo standard CN8-pole connector for lighting equipment quoted from the following non-patent document 1.
A CN8-pole M connector is attached to the end of the lighter wiring of the lighter (braking light, right turn signal, left turn signal, side light, backward light) to be attached to the agricultural work machine towed or attached to the tractor. A braking light, a right turn signal, a left turn signal, a side light, and a back light will be installed behind the farm work machine in a position that can be confirmed from the rear of the farm work machine in accordance with the regulations. The CN8-pole M connector provided on the agricultural work machine side at the end of the wiring of the lamp is connected to the CN8-pole F connector mounted on the tractor, so that the brake light is linked to the operation such as braking on the tractor side. Etc. are designed to light up.

When importing a tractor from a foreign country, especially from Europe, the lamp connector attached to the European-made tractor is a DIN standard connector and does not have a CN8-pole connector. For this reason, it is not possible to directly connect the CN8-pole connector of the Japanese agricultural industry standard attached to the agricultural work machine made in Japan.
Moreover, in Europe, it is not obligatory to install a backlight, so the DIN standard connector does not have a corresponding terminal for the backlight, and the wiring of the backlight can be installed via the DIN standard connector. There wasn't. Therefore, in order to turn on the backward light in conjunction with the backward operation from the power supply of the tractor, it is necessary to rewire the wiring to the backward light of the agricultural work machine, which is costly and troublesome.
For example, it is possible to attach a CN8-pole connector to a DIN standard connector using an adapter and connect the lighting fixture wiring of a braking light, a right direction indicator light, a left direction indicator light, and a side light, but for the back light, that is the case. I can't.

An object of the present invention is to solve the improvement of the connection workability of the lighting device wiring of the agricultural work machine.

The present invention includes a main body 31, a lamp output terminal 32, and an ISOBUS connector connection terminal 33. The ISOBUS connector connection terminal 33 is provided on the main body 31 and is associated with the lamp 51. It has a signal terminal 331 that receives the light device control signal 161. The main body 31 converts the light device control signal 161 into a power output associated with the light device 51, and the light device output terminal unit 32. Is a lamp control signal conversion unit 3 provided in the main body 31 and having an output terminal 321 for outputting the power output associated with the lamp 51, thereby solving the problem. bottom.

Cost and labor can be reduced by connecting the lighting equipment wiring by utilizing the ISOBUS connector of the international standard mounted on the tractor.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Example 1]
Example 1 is Example 1 relating to a Japanese-made agricultural work machine 2 towed by an overseas-made tractor 1. The agricultural work machine 2 may be towed or mounted behind the tractor 1.
FIG. 3 is a front view of the ISOBUS connector 14 as viewed from the terminal side. As described above, the DIN standard connector 12 is mounted as a connector for lighting equipment in the tractor 1 made overseas, especially in Europe. Then, in addition to the DIN standard connector 12, the ISOBUS connector 14 (International Organization for Standardization standard) is generally mounted on the tractor 1. ISOBUS (ISO 11783) is a standard corresponding to the CAN (Controller Area Network) communication protocol for network control of agricultural machinery.
The first embodiment is a mode in which the lighting device wiring 5 on the farming machine 2 side is connected to the ISOBUS connector 14 instead of connecting the lighting device wiring 5 on the farming machine 2 side to the DIN standard connector 12.

FIG. 4 is a conceptual diagram of wiring from the tractor 1 to the lighting device 51 of the agricultural work machine 2. Further, FIG. 6 is a wiring conceptual diagram.
A lighting signal 6 which is a power output for lighting the braking light 511 and the left-right direction indicating light (512, 513) is output to the tractor 1 in accordance with the braking by the brake and the operation of the direction indicator, respectively. Although not shown in FIG. 4, a lighting signal 6 for lighting the vehicle side light 514 and the reverse light 515 is also output. These lighting signals 6 are usually wired so as to be sent to the DIN standard connector 12 in the European tractor 1.
In the present invention, the brake light 511, the left-right direction indicator light (512, 513), the vehicle side light 514, and the back light 515 are turned on by using the ISOBUS connector 14 without using the DIN standard connector 12.
In the first embodiment, as shown in FIG. 4, the vehicle side light 514 and the braking light 511 are shared by one lighting device 51, and the amount of light is increased several times when braking is applied. Of course, it goes without saying that the vehicle side light 514 and the brake light 511 may be provided independently.
The ISOBUS connector 14 mounted on the tractor 1 supports CAN communication as described above, and can output various control signals as CAN signals to various devices. A lighting signal 6 which is a power output for lighting the lighting device 51 is output in accordance with an operation such as braking in the driver's seat. The power output of the lighting signal 6 output to each lamp 51 is converted into the CAN communication standard lamp control signal 161 associated with the lamp 51 by the CAN signal conversion unit 4, and the bus wiring 16 It is sent to the ISOBUS connector 14 at the end through.

Then, the lamp control signal 161 (CAN control signal associated with the lamp 51) output from the ISOBUS connector 14 is sent to the lamp control signal conversion unit 3. The lamp control signal 161 (CAN signal) transmitted via the bus wiring 16 is converted into a power output associated with the lamp 51 by the lamp control signal conversion unit 3.

It will be described in more detail with reference to the whole conceptual diagram of the lamp signal conversion unit of FIG. The lamp control signal conversion unit 3 is mainly composed of a main body 31, a lamp output terminal 32, and an ISOBUS connector connection terminal 33.
The ISOBUS connector connection terminal 33 is provided on the main body 31, and a signal terminal 331 for connecting to the ISOBUS connector 14 on the tractor 1 side is provided.
The ISOBUS connector 14 has a built-in power supply line in addition to the communication line for performing information communication, and the main body 31 sends a CAN signal and sends a lighter control signal 161 associated with the lighter 51, respectively. It is converted into the power output associated with the lamp 51.
The light device output terminal unit 32 is provided in the main body unit 31 and has an output terminal 321 that sends power output to at least one light device 51 attached to the agricultural work machine 2. The output terminal 321 is associated with the lighting device 51, and the main body 31 sends a power output to a predetermined output terminal 321 according to the association.
In the first embodiment (FIG. 5), the CN8-pole F connector 8F is adopted as the lamp output terminal portion 32, but any one can be used as long as the power output can be sent to the lamp 51. Needless to say.

FIG. 6 is a wiring conceptual diagram of the first embodiment. Each of the 8-pole output terminals 321 provided on the CN 8-pole connector 8 is associated with each lamp 51 in advance, and the associated lamp 51 is configured to light up.
The end of the lamp wiring 5 is a CN 8-pole M connector 8M, and the CN 8-pole M connector 8M and the CN 8-pole F connector 8F can be connected. , The connection of each lighter wiring 5 of the left turn signal 513, the side light 514 and the back light 515 is completed at once.

FIG. 7 is a rear view of the fertilizer application work machine (agricultural work machine 2) with the lighting device 51 attached. At the rear of the fertilizer application machine (agricultural work machine 2), there are a right turn signal 512, a brake light 511 and a vehicle side light 514 unit, a left turn signal 513, a brake light 511 and a vehicle side light 514 unit, and a back light 515. , Although not shown, each lamp 51 is provided with a lamp wiring 5 according to the first embodiment.

As described above, even if the tractor is made in Europe and the back light 515 is not obligatory, it is possible to save the trouble of separately rewiring the power supply wiring.

[Example 2]
FIG. 8 is a wiring conceptual diagram of the second embodiment. In the first embodiment, the lighting device wirings 5 of all the lighting devices 51 are connected to the lighting device control signal conversion unit 3, whereas in the second embodiment, the lighting device control signal conversion unit 3 is limited to the back light 515. Connect to. The other lighting device 51 is an embodiment in which the DIN standard connector 12 is utilized (see “DIN standard connector route” in FIG. 8). Other configurations are the same as in the first embodiment.
The DIN standard connector 12 has terminals corresponding to the brake light 511, the right turn signal light 512, the left turn signal light 513, and the side light 514, but the invention states that there is no corresponding terminal only for the back light 515. I explained in the problem to be solved. Regarding the braking light 511, the right direction indicator light 512, the left direction indicator light 513, and the vehicle side light 514, the terminals assigned to each of the lamps 51 of the DIN standard connector 12 and the respective lamp wiring 5 are connected in the drawing. The connection is completed by using the DIN standard connector route.
On the other hand, since the DIN standard connector 12 is provided with a terminal corresponding to the back light 515, the back light 515 is turned on by the ISOBUS connector route in the figure. Specifically, the lighting signal 6 of the back light 515 is converted into a light device control signal 161 by the CAN signal conversion unit 4 and sent to the ISOBUS connector 14 through the bus wiring 16. Further, the lamp control signal conversion unit 3 connected to the ISOBUS connector 14 converts the power output into power output, and lights the receding light 515 through the lamp signal wiring 5 of the receding light 515.
In the second embodiment, since only the back light 515 is lit by the ISOBUS connector 14 route, it is sufficient that at least one output terminal 321 (see FIG. 5) of the lamp output terminal unit 32 is provided.
As a result, even if the tractor is made in Europe and the back light 515 is not obligatory, it is possible to save the trouble of redrawing the power supply wiring separately.

[Other aspects]
As another embodiment, if the ISOBUS connector route is used, it is possible to light the lamps 51 other than those illustrated in the first and second embodiments, if necessary, without rewiring. If a large number of poles of the output terminal 321 (see FIG. 5) of the lamp output terminal 32 is provided in advance as a spare output terminal 321, even if a new lamp 51 is added, it can be easily dealt with. can do. For example, a number lamp (a lamp 51 that illuminates a license plate), a tail lamp (tail lamp), and the like can also be connected by the ISOBUS connector route.
