Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a storage structure for a top plate support rod of a bonnet in a traveling vehicle such as an agricultural tractor.

[Problems to be Solved by Prior Art and Invention] Generally, in a traveling vehicle of this type, a bonnet is divided into front and rear chambers by a radiator, and one room (for example, a front room) has Arrange the member device,
There is one in which a member device such as an engine that generates heat or is resistant to heat is arranged in the other room. By the way, the bonnet is provided with a bonnet top plate for opening and closing it for maintenance, etc., but in such a thing, in order to hold the bonnet top plate in the open position, the space between the bonnet top plate and the machine body is kept. Although the top plate support rod was interposed in the above, this base plate support rod is pivotally supported at the base end and the tip end of a hook or the like in a storage posture in which the top plate support rod is stored along the inner peripheral surface of the bonnet top plate. The structure is a two-point support structure supported by the locking member, and the middle part remains unsupported and unstable. Therefore, there is a problem in that, when the vehicle travels in a highly uneven area such as a farm field, the top plate support rod is rattled due to the vibration of the machine body and an unpleasant noise is generated.

Therefore, it is conceivable that the middle part of the top plate support rod is also supported by a hook or other locking member.
In addition to the need for a new locking member, when the top plate support rod is placed in the storage position or the top plate support position, it is necessary to engage and disengage the midway part, which causes a problem of reduced workability. To do.

[Means for Solving the Problems] The present invention has been made in view of the above circumstances, and was devised for the purpose of providing a storage structure for a top plate supporting rod of a bonnet capable of eliminating these drawbacks. ,
On the top of the bonnet that opens and closes the ceiling of the bonnet in which the front and rear chambers are formed by partitioning the radiator, the tip end is detachably engaged with and supported by the body side member to hold the bonnet top in the open position. The base end portion of the top plate supporting rod is swingably supported, and the top plate supporting rod is configured to be stored in a storage posture along the inner peripheral surface of the bonnet top plate facing the front-back direction. In the traveling vehicle, the top plate support rod is
In the storage posture, the radiator portion is sandwiched between the front and rear portions, and the inner surface of the bonnet top plate projects toward the outer peripheral edge of the radiator to shield heat between the front and rear chambers of the bonnet. It is characterized in that the heat shield is integrally attached so as to come into contact with the top plate support rod in the stored posture, elastically deform and press this.

According to this configuration, the present invention allows the top plate support rod to
It is possible to prevent unnecessary rattling without requiring a new locking member.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.

The bonnet 2 at the front of the traveling machine body 1 is divided into front and rear chambers A and B with a radiator 3 as a partition, and the front chamber A is provided with member devices such as a battery 4 which is weak against heat, and the rear chamber B. A member device such as the engine 5 that generates heat or is weak to heat is disposed in the engine.

6 is a bonnet top plate for opening and closing the ceiling of the bonnet 2. The bonnet top plate 6 is a hinge on the body of the machine.
It is mounted so as to be openable and closable by means of 6a, but the inner peripheral surface of the bonnet top plate 6 projects toward the outer peripheral edge of the radiator 3 and comes into contact with the radiator 3 with the bonnet top plate 6 closed. A heat member 7 is attached, and the heat shield member 7 thermally shields the front and rear chambers A and B of the bonnet 2. Further, a top plate support rod 8 for holding the open top plate 6 is attached to the inner peripheral surface of the top plate 6, and the heat shield 7 is sandwiched between the top plate support rods 8. The base end is pivotally supported 8a on the rear chamber B side, and the tip end is releasably engaged with the hook 9 formed on the front chamber A side. It is adapted to be stored in a storage posture along the inner peripheral surface of the bonnet top plate 6 facing the direction. At this time, the heat shield 7 comes into contact with an intermediate portion of the top plate supporting rod 8 to elastically deform and press the top plate supporting rod 8, whereby the top plate supporting rod 8 is vibration-proofed. It is adapted to be stored in the inner peripheral surface of the bonnet top plate 6 in this state. The reference numeral 10 designates a hook formed on the side surface of the radiator 3, and by opening the bonnet top plate 6 and locking the tip of the top plate support rod 8 to the hook 10, the top plate support rod 8 The bonnet top plate 6 is supported between the bonnet top plate 6 and the body of the machine body so that the bonnet top plate 6 can be held in an open position.

Reference numeral 11 denotes a machine body frame (chassis) of the traveling machine body 1, and right and left frame members constituting the machine body frame 11.
A reinforcing member 12 having an inverted T-shape in a side view is provided between 11a and 11a, and a notch 12a is formed in an intermediate portion of the reinforcing member 12 for driving the front wheels. The shaft 13 is loosely fitted and protrudes forward. In this way, the protection of the shaft 13 below and on both the left and right sides is ensured by the frame material.
11a and the reinforcing member 12 are provided so that the shaft 13 can be protected from collision with obstacles, and when the shaft is broken, the shaft is broken.
It is possible to prevent the 13 from hitting the frame material 11a and jumping out to the outside of the machine body, and the structure is designed to improve safety.

Further, reference numeral 15 is a step-shaped device formed in a flat shape, and the step-device 15 is a left and right frame member 11.
Although it is supported on the upper surfaces of a and 11a, a reinforcing pipe 16 is further supported between the left and right frame members 11a and 11a. The reinforcing pipe 16 is located outside the fuselage from the left and right frame members 11a and 11a. A support plate 16a is integrally attached to the tip end portion projecting from the. The support plate 16a receives and supports the outer side portions of the step deck 15 that project outward from the left and right frame members 11a, 11a, and thereby the step deck 15 is reinforced.

In the embodiment of the present invention constructed as described above, the top plate support rod 8 for holding the top plate 6 of the bonnet 1 in the open / closed posture is the bonnet top plate in the seismic-proof state in which the middle portion is pressed by the heat shield 7. 6 will be stored on the inner peripheral surface. Therefore, the top plate supporting rod 8 is affected by the heat-insulating material 7 when the vehicle travels in a place with severe irregularities such as a farm field, and thus the top plate supporting rod 8 has a supporting structure at two locations, that is, the base end portion and the tip end portion. Even though it is stored, it is possible to reliably prevent unpleasant noise from being generated due to vibration. Moreover, since the vibration of the top plate support rod 8 is effectively utilized by the heat shield 7 that thermally shields the front and rear chambers A and B formed by partitioning the bonnet 1, a separate seismic damper or Since it is not necessary to attach the locking member, the member can be commonly used and the structure can be simplified.

[Advantages] In short, since the present invention is constructed as described above, the bonnet top plate support rod, when housed on the inner surface of the bonnet top plate, is seismic-proof when pressed by the heat shield. Will be stored on the inner surface of the bonnet top plate. Therefore, when traveling in a place with severe irregularities such as a field, the top plate support rod is subject to the seismic effect of the heat insulating material and is stored in the support structure at two places before and after the provisional order. Also, it is possible to reliably prevent unpleasant noise from being generated by the vibration. Moreover, since the vibration of the top plate support rod can be effectively utilized by using the heat shield that thermally shields the front and rear chambers formed by partitioning into the bonnet, the members can be used in common and the structure can be simplified. A reduction in the number of parts can be achieved.
