Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a safety frame structure for a transport vehicle with a wagon.

(b) Conventional technology Conventionally, the driving section of a transport vehicle with a wagon has been equipped with a safety frame.
Left and right rising sections are erected from the left and right sides of the fuselage frame located between it and the wagon placed behind it, and the upper ends of each rising section are horizontally extended above the driver's section, and horizontally between the left and right extending sections. It is made of horizontal rods. Such a safety frame is located behind the operator who is seated in the driver's seat and performs various operations, and
It functions to protect the overhead area, and a canopy for sunshading can be installed on the extension of the frame as necessary.

(c) Problems to be solved by the invention However, the above-mentioned safety frame was weak in strength and required a reinforcing machine frame.

In other words, since the safety frame has a generally L-shape when viewed from the side with a rising part formed of a small-diameter pipe and an extending part, when a load is applied to the extending part, it acts on the rising part. The moment became large, and there were strength problems such as the rising portion being bent into a curved shape or broken.

(d) Means for solving the problem Therefore, in the present invention, the prime mover section is arranged on one side of the front part of the fuselage frame, the driving part is arranged on the other side of the front part, and the engine part is arranged on the other side of the front part. A safety frame structure for a transport vehicle with a wagon, in which a wagon is installed and a safety frame for protecting the driver is provided between the wagon and the driver and at a location on the outside of the fuselage frame. , the rising part of the safety frame is raised directly above the fuselage frame, and the upper end of the rising part is located at approximately the same height as the upper edge of the wagon, and the upper end of the rising part is located close to the wagon. A reinforcing frame is installed diagonally in a forward-leaning state between the outer part of the fuselage frame, and a plurality of horizontal beams are installed horizontally between the reinforcing frame and the rising part, so that it is easy to get on and off the wagon. It is an object of the present invention to provide a safety frame structure for a transport vehicle with a wagon, characterized in that a step portion is formed.

(e) Effect In this invention, when carrying cut grass, etc., is loaded into a wagon and carried out, a safety frame is installed between the wagon and the driving section.
The driving section is protected by the frame, and since the reinforcing frame is provided diagonally on the rising part of the frame, safety can be ensured by the safety frame.

Furthermore, since multiple cross bars are placed between the rising portion of the safety frame and the reinforcing frame to form a step section for getting on and off the wagon, the safety frame that is exposed to cross winds, etc. can be reliably reinforced, and workers can easily get on and off the wagon via the step section, enabling them to quickly perform tasks such as leveling grass stored in the wagon and removing foreign objects.

Furthermore, the reinforcing frame is diagonally installed between the upper end of the rising portion and the outer part of the body frame adjacent to the wagon, and a step portion is formed by lining up multiple cross bars between the two frames, so that the gap formed between the driver's section and the wagon can be made into a closed protective fence on the outer part of the body frame, preventing the danger of children etc. easily entering this gap.

(F) Effect According to the present invention, the safety frame is reinforced with a reinforcing frame, and a plurality of horizontal beams are interposed between the frame and the rising part of the safety frame, so that the safety frame is strengthened. This has the effect of improving strength and ensuring safety.

(G) Example The example of the present invention will be explained in detail based on the drawings.
A shown in FIG. 1 is a transport vehicle with a wagon, and the transport vehicle A has a prime mover section 2 on the front left side of the body frame 1, a driver section 3 on the front right side, and a wagon 4 behind these. The structure is such that transportation can be carried out by means of front and rear wheels 5 and 6, which are arranged in series at the front and rear of the body frame 1.

The driver section 3 has a handle 8 protruding from a dart board 7 at the front, a seat 9 behind it, and a fuel tank 10 adjacent to and behind the seat 9.

The wagon 4 is formed into an upwardly opening box shape with a substantially inverted large shape when viewed from the side, and has left and right side walls 4a, 4a and a front side wall 4b made of a mesh body, and the front side wall 4b is tilted forward. In addition, the rear side wall 4c is tilted backward.

The wagon 4 is configured so that it can be tipped over and dumped rearward by a dump cylinder 12 interposed between a wagon support frame 11 provided on the rear part of the body frame 1 and an upper frame 4d of the wagon 4. .

The wagon 4 is loaded with grass, etc. from a mower or the like installed at the front of the machine.

Further, a safety frame 13 is provided between the driving section 3 and the front side wall 4b of the wagon 4, and the safety frame 13 has left and right rising parts 13a, 13a vertically arranged above the body frame 1, The upper end of each rising portion 13a, 13a extends horizontally from a position slightly above the upper end of the front side wall 4b of the wagon to a position above the front handle 8 to form horizontal portions 13b, 13b, and each horizontal rising portion 13a, 13a A frame-like frame is constituted by horizontally extending horizontal rods 13c between the intermediate portions.

The gist of the present invention is that the safety frame 13 is provided with a reinforcing frame 14, and a plurality of horizontal bars 15a are interposed between the reinforcing frame 14 and the rising portion 13a of the safety frame 13. That's right (see Figure 2).

That is, the reinforcing frame 14 is formed into an upper and lower vertically elongated rod, and its upper end is connected to the upper ends of the left and right rising parts 13a, 13a of the safety frame 13, and its lower end is connected to the fuselage frame 1 with a slight distance from the lower end of the rising parts 13a. By being connected to the front side wall 4b of the wagon, the front side wall 4b is inclined forward and substantially parallel to the front side wall 4b of the wagon.

A horizontal bar 15a is interposed horizontally between the reinforcing frame 14 and the right rising portion 13a. The frames 14 and 13a are horizontally mounted with a distance maintained between them,
The horizontal beam 15a constitutes a step portion 15.

In the figure, 15b indicates an auxiliary step provided on the side wall of the fuselage frame 1, and 16 indicates an assist and auxiliary rod. Further, 17 indicates a canopy.

Therefore, according to the present invention, the safety frame 13 is reinforced by the reinforcing frame 14 and the step part 15, and its strength is improved.
Since the wagon 4 can be freely entered and exited through the wagon 4, even if foreign matter gets mixed in during loading and unloading of grass, etc., the foreign matter can be quickly removed.

Moreover, the reinforcing frame 14
Since it is installed diagonally substantially parallel to b, it has an aesthetic effect that gives a sense of unity in terms of design.

Furthermore, the reinforcing frame 14 and the step portion 1
5, the space between the driving section 3 and the wagon 4 is closed, thereby preventing a person from easily entering the space between the drive section 3 and the wagon 4.
