Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a protection structure for a plurality of connecting wires wired to a working machine such as a rice transplanter.

[Prior art and problems to be solved by the invention] Generally, in this type of working machine, there is one in which an operating means such as a lever and an operating means such as a clutch are connected via a connecting wire. By the way, if the working machine is a walking rice transplanter, for example,
A control operating section for controlling the longitudinal and lateral postures of the aircraft is provided approximately in the center of the aircraft.In such a device, when the connecting wire is routed back and forth beyond the control operating section, The connecting wire must be carefully protected from contact with the operating parts.

However, today, with the demand for more compact aircraft bodies, it is difficult to secure a wide wiring space for the connecting wires, and the reality is that there are restrictions. In order to avoid contact, it may be necessary to bend the connecting wire or take a long detour, and in this case, the connecting wire becomes long and there is a lot of waste. However, there are disadvantages such as increased loss of wire operating force and impairing smooth wire operation.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing a protective structure for connecting wires that can eliminate these drawbacks. When wiring a plurality of connecting wires for connecting the means and a plurality of actuating means provided at intervals corresponding to each of these operating means in a corresponding manner, beyond the actuating part,
At least one of these connecting wires is hard and the rest are soft, and the hard connecting wires are on the side facing the actuating part and the soft connecting wires are on the side away from the actuating part. In this structure, the wires are laid so that they cross each other on the way beyond the actuating part, and the contact of the soft connecting wire with the actuating part is restricted and protected by using the hard connecting wire as an aggregate. It is characterized by the fact that

With this configuration, the present invention enables effective protection without bending the connecting wire or making a circuitous detour.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a traveling body of a walking rice transplanter, and an engine 2 is installed in the front of the traveling body 1.
is mounted, and members such as a seedling stand 3, a driving handle 4, and planting claws 5 are provided at the rear, as in the past. Further, approximately at the center of the fuselage 1, there are a cylinder 6 for longitudinal attitude control that controls the longitudinal attitude (pitching) of the fuselage 1, a cylinder 7 for lateral attitude control that controls the left and right horizontal attitude (rolling), and Various control operation members A, such as a valve device 8 that controls the expansion and contraction operations of these cylinders 6 and 7, and a balance device 10 that is linked to the running wheels 9, are provided.

The operating handle 4 is provided with a side clutch lever 11. One end of the connecting wire 12 is connected to the side clutch lever 11, and the other end of the connecting wire 12 is operatively connected to a clutch arm 14 provided on the transmission case 13. The side clutch can be engaged and engaged by operating the side clutch lever 11. In the embodiment, the outer part of the connecting wire 12 is made of a hard cylinder, and the wires are wired so as to cross over the control operating part A in the approximate center of the fuselage in a horizontally inclined cross state. . Reference numeral 15 denotes a wire clip (which may be a wire band) formed in a plate shape, and the lower surface of the wire clip 15, that is, the side of the control operation section A, has a portion extending beyond the control operation section A of the connecting wire 12. A first engagement groove 15a for engaging and holding is formed at an intermediate position, and a second engagement groove 15b facing in the front-rear direction so as to intersect with the first engagement groove 15a is formed on the opposite upper surface. . The second engagement groove 15b includes a planting clutch connecting wire 16 and a running clutch connecting wire 1.
7. A plurality of soft connecting wires, such as the tie yoke connecting wire 18, whose outer parts are softer than the connecting wire 12, are engaged and held and wired in the front-rear direction.

In the embodiment of the present invention constructed as described above, the attitude of the aircraft is controlled by the expansion and contraction operations of both cylinders 6 and 7, and a group of connecting wires is wired above these control operation parts A. However, the connecting wire group will be effectively protected from contact with the control actuator A. That is, among these connecting wires, the hard connecting wire 12 and the remaining soft connecting wires 16, 17, and 18 are arranged such that the hard connecting wire 12 is located on the side facing the control operation part A, and the soft connecting wire 16 is located on the side facing the control operation part A. , 17, and 18 are wired so as to cross each other at a position on the way beyond the control operation part A while being located on the side away from the control operation part A, and a hard connecting wire 12 located on the control operation part A side. acts just like an aggregate to prevent the soft connecting wires 16, 17, and 18 wired on the side away from the control operation section A from coming into contact with the control operation section A, thereby protecting the control operation section A. Therefore,
Unlike in the past, there is no longer a need to bend the connecting wire group or take a circuitous detour to prevent contact with these operating parts A, and the wiring can be wired in a substantially straight line, which is the shortest distance. Become. Therefore, the group of connecting wires can be effectively protected, and the loss of operating force caused by bending the wires is also reduced, making it possible to perform light operation.

It should be noted that the present invention is of course not limited to the above-mentioned embodiments, and the point is that at least one hard connecting wire is effectively used as an aggregate, and the remaining soft connecting wires are used in the actuating part. It is acceptable as long as it is possible to control contact, and for that reason,
It is sufficient that the soft connecting wires are located on the side facing the actuating part and the soft connecting wires are located on the side away from the actuating part, and that they are wired so that they cross each other at a position on the way beyond the actuating part. Therefore, it is sufficient to use one hard connecting wire, or it may be three or more.Furthermore, the group of connecting wires does not cross over the actuating part on the upper side, but on the left and right sides. Furthermore, the wire clip is not necessarily necessary, and the point is that the hard connecting wire acts as an aggregate and restricts the contact of the soft connecting wire with the actuating part. For this reason, it is sufficient that the connecting wires can be maintained in a crossing state during the wiring.

[Operations and Effects] In summary, the present invention is constructed as described above, and among the plurality of connecting wire groups that connect the operating means and the actuating means in a corresponding relationship, the hard connecting wire is connected to the actuating section side. , and the soft connecting wires are located on the outside and intersect on the way beyond the actuating part, so that the hard connecting wires on the actuating part side function as the aggregate for the soft connecting wires on the outside. This prevents the soft connecting wire from coming into contact with the actuating part. As a result, even if the connecting wires are wired in a straight line over the actuating part to achieve the shortest distance, at least one hard connecting wire must be used effectively to make contact with the actuating part. This makes it possible to route the connecting wires without having to bend them multiple times or take long detours as in the past, eliminating waste, and reducing the loss of wire operating force. This means that the operation can be performed.
