Description

[Detailed Description of the Invention] The present invention relates to an agricultural tractor in which an engine and its accessory parts are disposed at the front of the machine body.

Generally, agricultural tractors with an engine mounted in the front have large engine vibrations, so the radiator is attached directly to the machine frame via a cushioning material such as a rubber-like elastic body.
Air cleaners were installed in front of the engine or on the outside of the hood to prevent hot air from being absorbed by the engine, but in order to make the aircraft resistant to engine vibrations, it was necessary to cover both the left and right sides of the engine. The integrated cover and the wind shield installed behind the engine are not enough; they must be reinforced with a special reinforcing frame, which increases the weight of the aircraft and complicates the assembly process, leading to high costs. It was also accompanied by

The present invention was devised in view of the above-mentioned actual circumstances and to eliminate these shortcomings. In an agricultural tractor, an assembly unit is formed by mounting brackets disposed on both left and right sides of the front part of the engine, and a radiator and an air cleaner located between the two mounting brackets and disposed in front of and above the engine, respectively. The lower end of the mounting bracket is fixed to the fuselage frame, and the mounting bracket has an integrated cover that covers both left and right sides of the engine and has a wind shield plate at the rear end to block hot air from the engine. By fixing the radiator and air cleaner to the mounting bracket, components such as a radiator and an air cleaner can be mounted between the mounting brackets to form a unit, which simplifies the assembly of the agricultural tractor. Furthermore, since the covers on both the left and right sides of the engine are fixed to this unitized mounting bracket, these parts are integrated into a single rigid body surrounding the engine. Therefore, it is an object of the present invention to provide an agricultural tractor that can sufficiently resist engine vibration.

To explain the configuration of the present invention with reference to an embodiment shown in the drawings, 1 is a body of an agricultural tractor, 2 is a front wheel thereof, 3 is a rear wheel, and a seat seat is provided at the rear of a body frame 1a of the body 1. 4, and a driving handle 5 is provided in front of the seat 4.

A bonnet 6 provided at the upper front of the fuselage 1 is pivoted via pivot pins 7.7 so as to be able to open and close in the front and rear directions of the fuselage 1.

8 is an engine mounted on the front part of the fuselage frame 1a, 9
, 9 are a pair of mounting brackets provided on both sides of the front left and right sides of the engine 8, and the lower portions of the mounting brackets 9, 9 are tightened to the fuselage frame 1a) 10.10...
It is fixedly installed via...

A radiator 11 disposed in front of the engine 8 and both side edges of a shroud plate 12 of the radiator 11 are fixed to mounting brackets 9 through tightening bolts 10.

13 is an air cleaner, and the air cleaner 13 is attached to the mounting bracket 9 so as to be positioned above the engine 8.
, 9 is fixed to an air cleaner bracket 14 via a tightening bolt 10.

That is, a radiator 11, its shroud 12, and an air cleaner 13 are interposed between the mounting brackets 9, 9, respectively, and these constitute an assembly unit 15 surrounding the front and upper portions of the engine 8.

Numerals 16 and 16 are integrated covers that cover both left and right sides of the engine 8, and the front part of the integrated cover 16 is connected to the mounting bracket 9.
．． The upper and lower tightening bolts 10°10 overlap at the rear of 9.
A wind shield plate 19 is fixed to the rear end of the engine 8 to prevent hot air from the engine 8 from blowing onto the fuel tank 17 and battery 18 located behind the engine 8. .

Note that 20 in the figure is a muffler extending from the engine 8.

Next, the operation of the present invention, which is structured like an upward slope, will be explained.

Now, when the engine 8 of the agricultural tractor is started, the assembly unit 15 surrounding the engine 8,
The integrated cover 16, 16 and the windshield plate 19 act as a rigid body, so it is possible to construct a structure that is stronger than the strength of each component without using a separate reinforcing member.
Therefore, it is possible to sufficiently resist the vibrations of the engine 8,
As the weight of the aircraft body 1 can be reduced, its configuration can be simplified.

Furthermore, when assembling the agricultural tractor, the radiator 11. Since the assembly unit 15 equipped with the shroud 12, air cleaner 13, and air cleaner mounting bracket 14 can be assembled separately, the assembly process can be simplified and the efficiency of the assembly work can be improved. During inspection, the engine 8 can be easily exposed by attaching and detaching the assembly unit 15, so that the work efficiency can be greatly improved.

In summary, the present invention provides an agricultural tractor in which an engine and its attached parts are disposed in the front part of the body frame, and a mounting bracket disposed on both left and right sides of the front part of the engine, and a surface mounting bracket. The assembly unit is composed of a radiator and an air cleaner, which are located between the brackets and arranged in front and above the engine, respectively, and the lower end of the mounting bracket is fixed to the aircraft frame, and the mounting bracket has a Since it is an integral cover that covers both the left and right sides of the engine and has a wind shield plate at the rear end to block hot air from the engine, it is easy to assemble parts such as the radiator and air cleaner that are unitized to the mounting bracket. And since it is easy to use, its configuration is also simplified, which reduces costs.Furthermore, engine inspection and maintenance become easier, greatly improving work efficiency.
Moreover, since the cover is integrally fixed to the mounting bracket,
These members surround the engine and act as a single rigid body, and therefore have extremely useful practical effects such as being able to sufficiently resist engine vibrations without using any reinforcing members. be.
