Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to the canopy of a working vehicle, particularly an excavator.

Prior Art FIG. 4 shows the structure of a conventional excavator and its canopy mounting structure.

In the figure, 1 is a lower traveling body, and an upper rotating body 2 is mounted on this lower traveling body 1. An engine 6 covered by an engine cover 4 is mounted on the rear end of the upper revolving body 2.
A seat 3 is arranged on the front side. 7 is an excavating machine attached to the front end of the upper revolving structure 2.
The engine cover 4 has an opening/closing lid 8 on its rear side that opens in the direction of arrow A. The canopy 9 consists of a canopy roof 10 placed above the seat 3 and a canopy frame 11 that supports the canopy roof 10. The lower end of the canopy frame 11 is placed above the engine cover 4 at the rear of the seat 3. Fixed to .

Problems to be solved by the invention In the conventional excavator mentioned above, the seat 3 is placed on the front side of the engine 6, but this increases the overall length of the machine, and the engine is relatively placed at the rear. Since it protrudes, the protruding portion collides with an obstacle when the revolving superstructure turns, resulting in a short turning radius. The large turning radius of this type of small excavator is a big disadvantage, and it greatly limits its range of use. Therefore, it is conceivable to arrange the engine below the seat, as shown by the two-dot chain line in the figure, which is the first purpose of this invention. In that case, in the conventional structure in which the lower end of the canopy frame 11 is attached to the front end portion of the engine cover 4, the pillars 12 of the canopy frame 11 are located on the sides of the seat 3 and on both sides of the operator. Therefore, there is an inconvenience that this pedestal 12 becomes an obstacle to the operation of the operator. Of course, if the canopy frame 11 is attached to the rear end of the engine cover 4, this problem will disappear, but as mentioned above, the opening/closing lid 8
Since the canopy frame 11 is rotatably attached, the canopy frame 11 cannot be attached to the rear side of the seat 3.

This invention was made for the purpose of eliminating such conventional drawbacks.

Means for Solving the Problems In order to achieve such an objective, this invention consists of a lower traveling body and an upper revolving body, and
In a work vehicle that covers the upper part of the seat with a canopy, an excavating machine is attached to the front part of the upper revolving body, and a seat and an engine placed directly below the seat are also provided at the rear, so that the seat and the excavating machine are connected. The cover covering the engine is divided into a main body part on the front side fixed to the upper revolving body and an opening/closing lid on the rear side, and a mounting base at the lower end of the canopy frame is attached to the seat. The engine cover is attached to the main body on both sides, and the rear end of the mounting base is bent upward at the rear of the control space of the operator who operates the control device to form a pedestal, and the sides of the control space are left open. Furthermore, a canopy roof is supported at the upper end of the pillar.

Function The mounting base 29 of the canopy frame 30 is
It is attached to the engine cover 24 on both sides of the seat 26, so it does not get in the way of the opening/closing operation of the opening/closing lid 25 of the engine cover 24. Moreover, the pedestal 35 bends the rear end of the mounting base 29 upward. Since it is curved, it does not obstruct the operations of the operator located on the seat 26.

Embodiment Hereinafter, the configuration of this invention will be explained based on the illustrated embodiment. In FIG.
An engine 23 is mounted on the rear part of the upper revolving structure 22, and the engine 23 is covered with an engine cover 24 as in the conventional case. This engine cover 24 is attached to the upper revolving body 22
It is divided into a main body part 20 on the front side, which is fixed to the front side, and an opening/closing lid 25 on the rear side, and the opening/closing lid 25
is designed to be opened and closed by rotating its upper side rearward as indicated by arrow A in the figure. A seat 26 is attached to the upper surface of the engine cover 24 directly above the engine 23. Reference numeral 27 indicates a lever mount mounted on the upper revolving body 22 in front of the seat 26, and 28 indicates an excavating machine also attached to the front end of the upper revolving body 22. A control section 37 consisting of various levers protruding from the lever mounting base 27 and the front part of the engine cover 24 is provided between the excavating machine 28 and the engine 23.

Reference numeral 29 in FIG. 1 is a pipe-made mounting base of the canopy frame 30, and this mounting base 29
As shown in FIG. 2, these are disposed on the upper surface of the main body portion 20 of the engine cover 24 on both sides of the seat 26 so as to face in the front-rear direction. In the figure 3
Reference numeral 1 denotes a mounting base fixed to the upper surface of the engine cover 24, and the mounting base 29 is placed on this mounting base 31, and the mounting base 2
A generally Ω-shaped holding plate 32 covering the mounting plate 9 is fixed to the mounting base 31 at both left and right ends thereof with bolts 33, 33, thereby supporting the mounting base 29. In addition, this presser plate 3
2 is provided over almost the entire length of the mounting base 29, as shown in FIG.
It is fixed with bolts 33, 33 at locations. 34 is a roughly inverted U-shaped handrail fixed to the upper surface of one of the presser plates 32.

The rear end of the mounting base 29 fixed as described above is bent upward through the bending part 34 to form a pedestal 35, and a canopy roof 36 is supported by the upper end of this pedestal 35. There is. That is, the pedestal 35 stands upwards at the rear of the control space for the operator who is located in the seat 26 and operates the control unit 37, and the sides of the control space are open, so that the canopy The structure is such that the operator's arm or elbow does not come into contact with the piano frame 30 and interfere with the operation.

Effects of the invention As described above, first of all, with this invention, the engine is placed directly under the seat, so the engine does not protrude far behind the seat, and the overall length of the aircraft is shortened. It is possible to obtain a working vehicle with a small turning radius, which is also required for a small excavation vehicle. Moreover, since the canopy frame also has its mounting base located on the side of the seat, the overall length of the aircraft can be made shorter and the turning radius smaller than when the mounting base is located at the rear. In addition, since the mounting base is fixed to the main body, which is the part where the engine cover is fixed to the upper revolving structure, the mounting strength is strong, and the rear part, which is divided into front and rear parts, is attached to the main body. There is no obstruction to the opening and closing of the opening/closing lid, and since the opening/closing lid is of such a divided structure, when the opening/closing lid is opened, the operating section at the rear of the engine is largely exposed, which facilitates engine maintenance work. In particular, in this invention, the engine is placed directly under the seat to shorten the overall length, and the mounting base of the canopy frame is attached to the main body of the engine cover.
The rear end of the mounting base is bent upward at the rear of the control section to support the canopy roof, and the sides of the control section are left open so that the operator's arms and hands can be attached to the canopy frame during control. This has the effect of preventing your elbows from hitting each other.
