Description

[Detailed explanation of the invention] In conventional tractors without a cabin, only a step plate was installed at the bottom of the control section, leaving the footwell open. There is a risk of mud being scattered on the ground, and if the aircraft were to tilt to the side or roll over, the pilot's feet would come off the suspension, causing the passenger's posture to collapse or fall off. There was a risk that my foot would come into contact with something else outside the aircraft.

This is because the transmission frame of a tractor, which connects the engine equipment section at the front of the machine and the seat section at the rear, is generally narrow in the left-right direction, so the step plate has no choice but to protrude outward from the side of the frame. Despite the various troubles mentioned above, the current situation is that we have no choice but to settle for a structure in which step plates are simply attached to the left and right outer walls of the frame.

The present invention aims to solve the above problems and improve livability and safety.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

The figure shows an agricultural tractor, and the front part of the machine is supported by a pair of left and right front wheels 1.1 and a pair of left and right rear wheels 2, 2.
The engine 4 is covered with the bonnet 3. Engine equipment such as a radiator 5 is installed, and a control handle 7 is provided at the rear of the engine equipment.Furthermore, a seating section with a control seat 6 is provided at the rear of the control handle 7, and the engine equipment is equipped with engine equipment such as a radiator 5. The seat section is connected to the engine equipment at the front end and the seat section at the rear end by a transmission frame 19 which is narrow in the left and right direction.

A pair of left and right step plates 8 a are provided at the bottom of the control section.
, 8b are provided.

These step plates 8a, 8b are received and supported by a pair of front and rear frame members 9a, 9b fixed to the transmission frame 19 in a horizontal position, and side plates 10a, 10b extend from the front and lateral outer edges thereof. They are installed consecutively.

The upper ends of the side plates 10a and 1Ob are connected to a frame member 11 that protrudes from the fuselage body, increasing the strength of supporting the fuselage body.

In the figure, 14a and 14b are a pair of left and right brake pedals, 15 is a running latch petal, and the side plate 1
Covered by 0a and 10b.

Reference numeral 12 in the figure denotes a safety frame that covers the pilot seat 6, and the side plate 10a, 10a, 10b can be attached to the front end side of the safety frame 12 using the mounting holes 13 formed in the side plates 10a, 10b (see Fig. 3).
10b, and its rear end side is supported by a mounting frame 17 which is connected and supported by the transmission case 16 of the rear wheel 2.degree. 2, as shown in FIG.

The mounting frame 17 is attached to the fender 1B of the rear wheels 2, 2.
, 1B is also used as a frame to reinforce it.

In summary, the tractor according to the present invention has engine equipment such as an engine and a radiator disposed at the front end of a transmission frame that is narrow in the left and right direction, and a control handle is provided at the rear of the engine equipment, and furthermore, a control handle is provided at the rear end of the transmission frame. In a tractor having a seat section equipped with a driver's seat, a step plate is received and supported by a pair of front and rear frame members that protrude laterally outward from both left and right sides of a transmission frame, and the front end of the step plate is A frame member is provided on the upper side of the body so as to protrude laterally outward from the fuselage, and the upper end of this frame member and a side plate provided in a continuous manner upward from the front edge and the lateral outer edge of the step plate are connected to the frame member. In other words, a frame member is provided on the back side of the step plate protruding from the transmission frame toward the side, and a frame member is also provided above the step plate protruding from the body. However, because the step side plates are connected across these upper and lower frame members, the strength of the step side plates is significantly greater than, for example, simply bending the front end of the step plate upwards. In addition, the front and outer sides of the pilot's feet are now covered by these strong side panels, which prevents scattered mud from falling on the operator, and from falling outside the aircraft in the event of a tilt or rollover. It eliminates the danger of other objects coming into contact with the worker's feet, improving comfort and safety, and is a practical benefit that previously did not exist for this type of tractor. We have now been able to provide a foot protection structure.
