Description

[Detailed Description of the Invention] This invention relates to agricultural tractors, and more specifically, to types of agricultural tractors such as hydraulic drive tractors and power shift tractors in which the oil temperature in the transmission case tends to become high.

In this type of agricultural tractor, the transmission case is provided approximately in the center of the body of the agricultural tractor, and steering is performed while sitting in the driver's seat astride the transmission case. The feet of farm workers sitting on the machine are likely to come into contact with the high-temperature transmission case, resulting in discomfort and, in extreme cases, the risk of burns.

The present invention was devised to deal with the above problems.A shielding plate that hides the side of the mission case is installed at a predetermined distance on the side of the step plate that is connected to the aircraft body. The shielding plate is intended to prevent the above-mentioned discomfort.

The details of the present invention will be explained below based on the embodiments shown in the figures. In the figure, 1 is the body of an agricultural tractor, with front wheels 2 at the front of the body 1, and rear wheels 3 at the rear.
are each pivotally supported, and a transmission case 4 is integrally provided approximately at the center of the body 1. A pilot seat 5 is provided on the aircraft body 1 at the rear of the mission case 4, and a control handle 6 is provided at the front facing the pilot seat 5.
The cockpit 5 is placed astride the transmission case 4.
Sit on the vehicle, hold the control handle 6 in this state,
Trying to steer the tractor. Reference numeral 7 denotes a step plate provided on the side of the mission case 4, and the step plate 7 is attached to both the front and rear sides of the case 4 via stays 9, 9 fixed by bolts 8. This step plate 7 has support rods 10 vertically disposed at several locations on its lower surface, loosely inserted into the stay 9, and an elastic body 11 inserted between the step plate 7 and the stay 9.
It can be installed by interposing the

Therefore, in the above agricultural tractor, the present invention includes a heat shield plate 12 on the side of the transmission case 4 that hides the side of the case.
A bolt 13 and a bolt 8 for fixing the stay 9 are installed at a predetermined distance from the side of the step plate 7.
At the same time, a heat insulating material 14 such as a foam material is installed inside the heat shield plate 12.

At this time, the heat shield plate 12 and the step plate 7
As shown in the figure, it may be formed integrally with a single metal plate or the like. Further, as shown in the figure, a gap 15 is formed between the heat shield plate 12 and the mission case 4 without installing the heat insulating material 14 inside the heat shield plate 12, and the mission case 4 is It may be arranged to block the transmitted heat.

As described above, in the present invention, the mission case is integrally provided approximately at the center of the machine body, and the step plate is located on the side of the mission case and is connected to the machine body. The agricultural tractor is an agricultural tractor in which a person sits in the driver's seat while straddling the case and grasps the control handle in this state to steer the tractor. Since the step plate is separated from the side of the control seat by a predetermined distance, it is difficult for a farm worker sitting in the cockpit to have a sufficient line of sight at the foot position near the transmission case. Despite this, there is no longer any risk of discomfort or burns caused by the feet touching the hot transmission case when the tractor is being steered, and the tractor can be steered comfortably and safely.
