Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rat-proof structure used for preventing electric wiring in agricultural machines such as combine harvesters from rat-damage.

[0002]

2. Description of the Related Art Conventionally, as a rodent-proof structure for this type of agricultural working machine, as shown in Japanese Patent Application No. 5-60804 filed by the applicant of the present invention, a resin agent mixed with a rodent-proof agent is tape-shaped. It is well known that the rat-proof tape having the above-mentioned structure is wound around the necessary place of the rat-proof in the wire harness to prevent the electric wiring of the machine body from being cut by the rat.

[0003]

However, in the above-mentioned conventional structure, since the wire harness is wound around the wire harness to reduce the flexibility of the wire harness, the location of the wire harness is reduced. When the wire harness is bent, it is difficult to bend the wire harness while winding the rod-proof tape, so it is difficult to handle. It was also troublesome to wrap the rodent-proof tape in the bent state. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rat-proof structure for agricultural work machines that can be easily handled, such as being able to easily bend a wire harness in a rat-proof manner.

[0004]

[Means for Solving the Problems] To achieve the above object, a rat proof structure for agricultural working machines according to the present invention comprises a wire harness for connecting electrical equipments mounted on a machine body and a rat proof agent. It is characterized in that it is built in a certain corrugated tube and wired. Also, the corrugated tube to be inserted into the inner and outer communication holes of the partition wall that separates the inside and the outside of the control tower is sandwiched by the support members divided into two, and the support members close the inner and outer communication holes. It may be configured to be installed in the control tower. The operation and effect of this characteristic configuration are as follows.

[0005]

[Function] That is, since the wire harness is built in the corrugated tube containing the rodent-proofing agent, the wire harness keeps good flexibility together with the corrugated tube as compared with the one in which the rod-proof tape is wound around the wire harness. Moreover, it does not take time and effort to wind the rodent-proof tape around the wire harness. Further, the corrugated tube to be inserted into the inner and outer communication holes of the partition wall that separates the inside and the outside of the control tower is sandwiched by the support members divided into two, and the support members close the inner and outer communication holes. If installed in the pilot tower, the inside of the pilot tower will be closed, and the corrugated tube containing a rodent-preventing agent that the mouse dislikes will close the inside / outside communication hole portion where there is a possibility that the mouse will enter and exit Since it is inserted like this, it is possible to prevent the mouse from coming in and out of the control tower, and avoid the rat damage such as electric wires in the control tower being caught in the mouse.

[0006]

Therefore, the flexibility of the wire harness can be made easy to carry out the wiring while the rattling can be prevented, and the workability of the wiring can be improved. Furthermore, by inserting a corrugated tube containing a rodent-proofing agent so as to be sandwiched by a support member divided into two inside and outside communication holes for guiding electric wires to the control tower,
Since it is possible to prevent ratching in the control tower, it is possible to avoid the problem that the electrical equipment is unduly malfunctioned due to rattling.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 4 shows a combine control tower 1 as an example of an agricultural work machine. The control tower 1 is provided with a meter panel portion 2 on the upper surface thereof, and a microcomputer unit 3, a fuse box 4 and the like are provided inside.
This control tower 1 is equipped with a combine-shaped fuselage frame 5 by forming a sheet metal into a box shape, and a wire harness 6 in which a plurality of electric wires from a battery or the like are collected is provided in each control tower 1 Wired to connect to the device. More specifically, as shown in FIGS. 2 to 4, the control tower 1
The wire harness 6 wired inside has a corrugated tube 9 forming a bellows tube that is inserted into an inside / outside communication hole 8 of a partition wall 7 for partitioning the inside and the outside of the control tower 1 with support members 10 divided into two. It is installed in the control tower 1 in a sandwiched state and with the support members 10 and 10 blocking the inner and outer communication holes 8. These pair of support members 1
Nos. 0 and 10 each have a semi-circular cutout that matches the outer shape of the corrugated tube 9, and are provided with grommets 11 made of a soft rubber material along the edges of the cutouts. The tube 9 is sandwiched so as to be in close contact. The support members 10 and 10 are connected to the partition wall 7 by bolts or the like.

The corrugated tube 9 is formed by kneading a synthetic resin material and a rodent-proofing agent and molding them into a bellows shape.
Here, as a rodent-proofing agent, a component of hot pepper, nanamycin or the like is used. Then, as shown in FIG.
In the case of the wire harness 6 having the connectors 12 and 12 at both ends, the corrugated tube 9 is provided at the middle portion in the longitudinal direction thereof.
In addition to the interior of the corrugated tube 9,
The electric wire portion of the wire harness 6 between the connectors 12 and 12 is covered with seal covers 13 and 13 in which the connectors 12 and 12 are formed in a flat shape. The rounded portion and the end portions of the corrugated tubes 9 and 9 are wound together with rodent-proof tapes 14 containing a rodent-proof material. The seal cover 1
3 and 13 are made of soft synthetic resin containing a rodent-proof material.
The wire harness 6 constructed in the rod-proof state is connected to, for example, a connector connection portion of the microcomputer unit 3, and the connector 12 at the other end is connected to a power supply unit or the like (not shown).

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
