Description

[Detailed Description of the Invention] The present invention relates to the structure of a safety frame for a tractor, and its main purpose is to improve the accuracy and strength of rainwater flow guidance while facilitating logistics.

A gate-shaped safety frame is installed on the tractor surrounding the driver's seat to protect the driver from falling or rolling over accidents.

When the canopy portion of such a safety frame is provided with a sunshade roof, the sunshade roof and the gate-shaped support are usually constructed integrally.

The safety frame, which consists of a sunshade roof and a gate-shaped support, is large and very difficult to handle.

In particular, the tractor and safety frame are often handled separately for packaging and transportation, which increases the stock of the safety frame and makes logistics extremely troublesome.

Therefore, the present invention was devised in order to solve the problems of the conventional example.In a gate-shaped safety frame with a sunshade roof that is installed upright on the tractor body surrounding the driver's seat, the sunshade roof is It is divided into left and right sides, and has upwardly projecting ribs on the edges of the division, and the ribs are removably connected to each other along the longitudinal direction of the tractor, and are attached to the left and right edges of the awning roof along the longitudinal direction of the tractor. The sunshade roof is detachably attached to the upper part of the safety frame support.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a tractor body, which is a two-axle, four-wheel type tractor having a pair of left and right front wheels 2 and a pair of left and right rear wheels 3.

Reference numeral 4 denotes a tractor bonnet, which covers the engine.A control handle 5 is provided at the rear of the tractor bonnet 4, and a driver's seat 6 is provided on the tractor body 1 behind the handle 5.

Reference numeral 7 denotes a rear wheel fender, and the fenders 7 are connected to each other behind the driver's seat 6 by a reinforcing plate frame 8 that also serves as a dirt guard.

9 is a gate-shaped safety frame, and a gate-shaped support 10
and a sunshade roof 12 provided on the canopy part 11 of the portal support 10.

A base plate 13 formed at the lower end of the leg rod of the portal support 10 is removably attached to the top surface of the rear wheel fender 7 in this example via a bolt nut, and is attached here to surround both sides of the driver's seat 6. It is installed upright on the tractor body 1.

Note that the portal support 10 is made of metal such as a round pipe, a square pipe, or a solid bar.

The leg rod and the canopy part 11 are connected to each other via a curved part 14.

The sunshade roof 12 is made of a metal plate, a hard resin plate, etc., and in this example is divided into left and right parts by upwardly projecting ribs 16 and 17 along the direction of movement of the aircraft, and the left and right divided bodies 15A and 15B are It has a bilaterally symmetrical shape.

Each of the divided edges is provided with ribs 16 and 17, and the ribs 16 and 17 are abutted against each other and can be attached and detached by a plurality of bolt nuts 18.

Furthermore, the sunshade roof 12 has gutter portions 1 on its left and right edges.
9 is formed in the front-rear direction, and the gutter portion 19 is inclined downwardly toward the rear.

The rear inner surfaces of the left and right divided bodies 15A and 15B of the sunshade roof 12 are placed on the canopy part 11 of the portal support 10, and are detachably attached to the top of the portal support 10 by a plurality of bolt nuts 20. The sunshade roof 12 extends above the driver's seat 6 in the shape of an eave.

In the example shown in FIG. 4, the ribs 16 and 17 are directly overlapped, but in the example shown in FIG. 5, the ribs 16 and 17 are overlapped with an elastic sealing material 21 interposed between them.

Further, in the example shown in FIG. 6, the canopy portion 11 of the gate-shaped support 10 is formed into a hook-shaped divided portion 22 corresponding to the divided edge of the sunshade roof 12.

In addition, when dividing the sunshade roof 12, a plurality of dividing edges may be provided, and the number of divided bodies may be three or more.

In addition, in FIG. 1, 23 indicates an entrance and exit, and in FIG. 2, 24 indicates a hydraulic system.

According to the above embodiment of the present invention, the portal support 10 and the sunshade roof 12 are removed, and the portal support 10 is itself, and the sunshade roof 12 is the divided body 15.
By removing A and 15B, storing them, packaging them individually, and transporting them,
It facilitates logistics, reduces transportation costs, secures large-volume transportation, and facilitates loading and exporting to overseas locations.

Assembling is done by attaching the canopy part 11 of the portal support 10 and the rib 1.
The divided body 15A is polymerized and fixed via 6 and 17,
After attaching the sunshade roof 12 made of 15B with bolts and nuts, attach the base plate 1 of the portal support 10.
3 is erected and fixed on the rear wheel fender 7.

The safety frame 9 assembled in this way surrounds the driver's seat 6 and protects the driver from the tractor body 1 falling sideways.The safety frame 9 that has been assembled in this way protects the driver from falling over and overturning, and also blocks light with the sunshade roof 12.
6, 17, and guides the flow down through the gutter section 1.
9 will also provide downstream guidance.

And, the ribs 16 and 17 together with the downstream guide,
It also has the effect of reinforcing the sunshade roof 12.

In summary, the present invention has the following advantages.

Since the sunshade roof 12 and the gate-shaped support 10 are removable and fixed, even with a large stable frame 9,
They can be handled as so-called small items, which makes packaging and transportation convenient.

In particular, the sunshade roof 12 has ribs 16,1
Since it is divided through 7, it can be handled as a small item, making packaging and transportation more convenient, and when it is stored as divided bodies 15A and 15B, it has the advantage that it can be stored with a low bulk. There is.

Further, the sunshade roof 12, which is divided into left and right parts, is provided with upwardly projecting ribs 16 and 17 at the edges of the division, and the ribs 16 and 17 are removably connected to each other along the longitudinal direction of the tractor. Because there are
Even if the sunshade roof 12 is divided by the ribs 16 and 17, a reinforcing effect can be exerted, and it also has a flow guiding function for rainwater, etc., so that rainwater and the like will not stay on the sunshade roof 12.

Further, since the ribs 16 and 17 are arranged along the longitudinal direction of the tractor, the ribs 16 and 17 serve as a direction to block rainwater and wind while the tractor is running, thereby preventing wind and rain from entering the driver's seat 6.

Furthermore, the gutter portions 19 on the left and right edges of the sunshade roof 12 not only provide a reinforcing effect together with the ribs 16 and 17, but also serve as a flow guide for rainwater, etc. Since it is easy to put it into practical use, it has great practical benefits.
