Description

[Detailed description of the invention] [Industrial field of application] The present invention is a work traveling machine in which a working device section is connected to a traveling body and the working device section is remotely controlled from the traveling body. This invention relates to a remote control device for a work traveling machine whose parts can be freely replaced.

[Conventional technology and its drawbacks]

Conventionally, work traveling machines that connect a working device section to a traveling body and remotely control the working device section from the traveling body must originally be able to freely attach and detach various working devices with simple work. No.

However, the control cable (hereinafter referred to simply as the cable) used to remotely control the actual equipment is attached with tension applied to both cable ends, making it difficult to attach and detach it, and The drawback was that it took a long time to process and adjust the tension. Therefore, for those with a large number of cables, due to the troublesome work described above,
In reality, it is often the case that a plurality of work vehicles, such as tractors, are purchased, each consisting of a dedicated travel body and a working device section, each individually tailored to the purpose of the work. This requires a large amount of expense, requires a separate storage location, and is also troublesome to manage.

In addition, conventional work traveling machines have only been equipped with an actual working device section that allows for easy attachment and detachment of a remote control device for limited work content. Therefore, when performing a specific work by connecting the production equipment unit for complex work to the traveling body, the remote control device of the production equipment unit is not installed on the traveling body side, and the control lever provided on the production equipment unit is used. I try to do this by operating the . For this reason, while driving the vehicle, the driver turns around and operates the operating lever of the operating device, or the driver stops the vehicle, gets out of the vehicle, operates the operating lever of the operating device, and then operates the operating lever again. They had to perform irregular tasks such as getting on the vehicle and driving it.

In short, with conventional work traveling machines, it is not easy to connect the remote control device to operate the actual equipment, so you have to purchase a separate dedicated work traveling machine or work in inconvenient conditions. I was forced to.

The present invention has been developed to improve and eliminate the above-mentioned drawbacks of conventional work traveling machines, and to make it possible to easily attach and detach a remote control device between the traveling body and the actual working device section. It is an object of the present invention to provide a remote control device that can easily attach an actual equipment section for any complicated work to an individual traveling body.

[Means for solving problems]

The gist of the present invention is to connect an operating device section to a running body, transmit the power of an operating lever on the moving body side to the operating device section by means of a control cable and a tension spring connected to the cable, and In a work traveling machine that remotely controls a device section, in addition to the non-operating position and operating position of the lever, a relaxed position for replacing the actual device section is newly installed on the sliding guide plate of the control lever, and the control cable is A connecting device for attaching and detaching the cable end connector on the traveling body side and the cable end connector on the operating device side is provided in the intermediate portion, and the elastic action of the tension spring is canceled when the operating lever is set to the relaxed position. A remote control device for a work traveling machine, characterized in that the control cable is brought into an active state, the control cable is relaxed, and the tensile force (or compressive force) applied to the cable end joint in the coupling device is eliminated, thereby facilitating the coupling work. It is.

The configuration of the present invention will be described in more detail below based on the embodiments shown in the drawings.

〔Example〕

FIG. 1 shows the entirety of an agricultural machine 1 to which the present invention is applied, and is composed of a running body 2 and a rice transplanter 3 as a working device section connected to the running body 2.
Further, FIG. 2 shows an agricultural machine 5 in which a tiller 4 as an actual operating unit is connected to the traveling body 2. The mechanical connection between the traveling body 2 and the rice transplanter 3 or tiller 4 may be a direct attachment method such as a rear attachment method using a so-called three-point support method, an abdominal attachment method, or a front attachment method. It may also be a traction type connection. The rice transplanter 3 and tiller 4 are remotely controlled by a control lever 6 installed on the traveling body 2.

Next, the remote control device 7 will be explained with reference to FIGS. 3A to 3C. The device 7 includes an operating lever section 8 on the traveling body 2, an operated section 9 of the rice transplanter 3 or tiller 4, a control cable (hereinafter simply referred to as a cable) 10 connecting the two, and a control cable 10 connecting the two. The cable end connecting device 11 is arranged in the middle.

The operating lever section 8 includes an operating lever 6 whose intermediate portion is rotatably supported by a pin 6a etc. on a part of the main body of the traveling body 2, and the aforementioned operating lever fixed to a floor surface 2a etc. of the traveling body 2. 6 sliding guide plate 12. The guide plate 12 is formed with a sliding groove 13 for operating the operating lever 6 and a sliding groove 14 for relaxation continuous with the groove 13. Operation sliding groove 1
One end side of 3 (the right end in case of figure a in Fig. 3)
A is the operating position of the operating lever 6, and the other end B is the non-operating position. The left end side C of the relaxing sliding groove 14 is the relaxed position of the operating lever 6.

The cable 10 is a cable 10a on the traveling body 2 side.
and a cable 10b on the side of the operated part 9, and each cable 10a and 10b is composed of an outer casing 15 and an inner cable 16, respectively. The connecting device 11 consists of a connecting tube 17 and a cap 18 screwed into the connecting tube 17. The connecting tube 17 and the cap 18 are provided with outer casings 15,
15 are attached at one end side, respectively. The other end side of each outer casing 15, 15 is attached to a panel 19 of the traveling body 2 and a panel 20 of the rice transplanter 3 or tiller 4, respectively. One cable end 21 of the inner cable 16 on the cable 10a side is connected to the lower end of the operating lever 6, and the other cable end is inside the connecting tube 17.
It is connected to the zygote 22. Also cable 10

The illustrated connectors 22 and 25 are embodiments in which the ends of cylindrical bodies are formed into mating recesses that fit into each other. These joints 2 are located inside the connecting tube 17.
2 and 25 transmit only the power of the inner cables 16 and 16, and their mutual coupling relationship does not deviate.

Next, the operation mode of the remote control device 7 configured as described above will be explained.

First, when the operating lever 6 is in the non-operating position B, the operating rod 24 is in the non-operating state (the position indicated by the chain line in Fig. 3a and the state shown in Fig. 3b);
Due to the slight tension of the tension spring 26, the inner cables 16, 16 are not relaxed but remain taut. Rice transplanter 3 and tiller 4
The operated part 9 is not in a working state.

When the operating lever 6 is moved to the operating position A from the above-mentioned state, the inner cables 16, 16 become in the normal tensioned state, and the operating rod 24 of the operated part 9 is rotated to the position shown by the solid line in FIG. 3 or the tiller 4 is put into a predetermined agricultural work state.

The states of these non-operating positions B and operating positions A are the same as those of conventional agricultural machines, and there is no particular difference.

Next, a case will be described in which the rice transplanter 3 and the tiller 4 as the actual working equipment are changed to actual working equipment that performs other tasks. In this case, the operating lever 6 is first moved to the loosening groove 14 and placed in the loosening position C.
This brings the inner cables 16, 16 into a relaxed state. In this state, the actuating rod 24 of the operated portion 9 is in a non-operating state as shown by the chain line, and does not rotate counterclockwise from this position in view a of FIG. 3. Therefore, as shown in FIG. 3c, the inner cables 16, 16 are relaxed by eliminating the tension in the tension spring 26, and the connectors 22, 25 are in a free state. Next, as shown in FIG. 4, the cap 18 of the coupling device 11 is screwed off from the coupling cylinder 17. After that, the above zygote 2

uncoupling the mechanical link. At this time, the zygote 22,
The positional relationship between the connecting tube 25, the connecting tube 17, and the cap 18 does not change. Then, another working device is prepared, and the rice transplanter 3 or tiller 4 is replaced with the other working device.

After replacement, the traveling body 2 and the actual device may be mechanically connected, and the cable 7 may be connected in the reverse manner as described above.

As described above, in the agricultural machine 1 or 5 of this embodiment, the cable 7 can be attached and detached with a simple operation, and it can be applied to all kinds of practical equipment. In other words, it has excellent compatibility with actual equipment.

By the way, the present invention is not limited to the above-described embodiments, and can be modified as appropriate. For example, although we have explained the case where the actual equipment is a rice transplanter 3 or a tiller 4, other devices such as a ridge erecting machine, a puddling machine, a fertilizing machine, a seeding machine, a weeding machine, a loading machine, a transporting machine, etc. can also be used. Easy to install. Further, a plurality of remote control devices 7 may be arranged for one actual device section. Even in this case, the configuration and effects of each remote control device 7 are the same as in the above embodiment. Furthermore, operating rod 2
4, the non-operating position B and the operating position A of the operating lever 6 may be reversed depending on the operating state of the operated part 9 connected to the operating member 4.
may be formed continuously. Furthermore, depending on the state of the operated part 9, the tension spring 26
may be used to apply a compressive force to the control cable 10, but such alternative embodiments do not alter the gist of the invention.

[Effect of idea]

As explained above, in the present invention, the remote control device can be easily attached and detached, and has excellent compatibility with all kinds of actual devices. Therefore, it is only necessary to prepare various types of actual working equipment, and the number of dedicated traveling working machines consisting of traveling bodies and working equipment can be reduced, which is convenient in terms of cost reduction and maintenance such as storage management. In addition, the actual equipment can be operated from the top of the vehicle, making it easy to operate.
