Description

[Detailed Description of the Invention] The present invention relates to a hot air shielding plate mounting structure for a tractor.

Conventionally, a support frame is erected from the front end of the steps protruding from both sides of the lower part of the operating section, and the outer part of the hot air shielding plate is pivotally connected to the support frame, and the shielding plate is moved forward around the pivot joint. There are some models that can be opened and closed, but in this case, when the shield plate is opened, the front end of the shield plate is located forward and inside of the pivot joint, so hot air is emitted from the front engine part. The hot air is dispersed from the relatively narrow inlet to the rear and spread out to the side of the operating section, and almost no hot air is blown onto the feet of the operator seated in the operating section. There was an inconvenience that the heating function was not working properly.

In the present invention, by configuring the hot air shielding plate so that the outer half of the shielding plate rotates forward and the inner half rotates backward, hot air can be made to flow into the driving section in a converged state. , it is an object of the present invention to provide a structure for mounting a hot air shielding plate on a tractor.

The embodiment of the present invention will be explained in detail based on the drawings.
A indicates a tractor, and the tractor A has a prime mover section 2 provided at the front part of a body frame 1, a driving section 3 arranged at the rear thereof, and front and rear parts arranged at the lower front and rear parts of the frame 1. It is configured to be able to run on wheels 4 and 5.

The prime mover section 2 is equipped with an engine 6, a fan 7 is provided in front of the engine 6, a radiator 8 is arranged in front of the fan 7, and the front of the prime mover section 2 is arranged in front of the radiator 8. The front mask 9 allows the bonnet 10 to cover the upper part of the prime mover section 2.
Then, the left and right sides are connected to both cases 11 and 1.
1 and the mesh covers 12, 12, the heat generated from the engine 6 is cooled by the cooling air taken in from the front mask 9, and is discharged outwardly on both sides as hot air from the mesh covers 12, 12. It is configured as much as possible.

The hot air discharged from the net-like cover 12 can be guided to the driving section 3 or can be blocked through the hot-air shielding plates 13, 13 arranged close to the rear of the cover 12. It is configured.

That is, the hot air shielding plate 13 has steps 14 , 14 horizontally protruding outward from both sides of the lower part of the operating section 3 , and a support frame 15 erected from the front end of the step 14 . The mesh cover 12
A rectangular ventilation hole 16 is provided in the frame of the support frame 15, and the ventilation hole 16 is located close to the rear of the support frame 15.
The hot air shielding plate 13 is formed in almost the same shape as the ventilation hole 16, and L-shaped brackets 17 and 18 are connected to the top and bottom of the center, respectively. Then, a screw rod 19 is erected from the horizontal portion 17-1 of the upper bracket 17, and the upper end of the screw rod 19 protrudes from the upper center of the flange portion 15-1, which is provided to protrude forward from the outer peripheral edge of the support frame 15. At the same time, a nut 20 having an adjustment knob is screwed onto the protruding part, and a pivot pin 21 is inserted from the horizontal part 18-1 of the lower bracket 18.
The hot air shielding plate 1
3 is configured to be rotatable around a screw rod 19 and a pivot pin 21.

In addition, a stopper body 23 formed in a rectangular plate shape is provided in a row on the outside central part of the front side of the hot air shielding plate 13 so as to extend outwardly. The stopper body 23 is configured to abut on the outer front side surface, and the rotation range of the outer half 13-1 of the shielding plate 13 is always in the front position of the support frame 15, and conversely, the rotation range of the outer half 13-1 of the shielding plate 13 is always in the front position of the support frame 15.
The rotating range of No. 2 is configured to be at the rear of the support frame 15, and a hot air passage gap S tapering backward is formed inside the ventilation hole 16 by the inclined shielding plate 13.

In the figure, 24 is a protection tube that surrounds and protects the screw rod 19.

The embodiment of the present invention is constructed as described above, and the heat generated by the engine 6 is absorbed through the radiator 8 by the air sucked in through the front mask 9, and is absorbed through the mesh covers 12, 12. The hot air is discharged outward on both sides, but the support frame 1
The hot air holes 16 formed within the frame of 5 are connected to the hot air shielding plate 1.
3, the hot air will not be blown onto the feet of the operator seated in the operating section 3, and if the hot air shielding plate 13 is in the open state,
Hot air flows in through the hot air passage gap S and is blown at the operator's feet, providing a heating function. With the inner half 13-2 located at the rear, the inclined hot air shielding plate 13 is tapered on the inside of the ventilation hole 16, so that the hot air discharged from the mesh cover 12 is Together with the air flowing along the side surface of the tractor A, the hot air is guided by the inclined hot air shielding plate 13, and flows reliably and forcefully through the gap S toward the driving section 3.

According to the present invention, since the hot air shielding plate is configured so that the outer half of the shielding plate rotates forward and the inner half rotates backward, the hot air discharged from the mesh cover is tilted. The hot air is guided by the hot air shielding plate and is reliably blown onto the operator's feet without being dispersed, providing an efficient heating function.

Claims (1)

[Scope of Claim for Utility Model Registration] A prime mover section 2 is provided at the front of the fuselage frame 1, and a driving section 3 is arranged at the rear of the prime mover section 2, horizontally outward from the left and right sides of the lower part of the driving section 3. Step 1
4 and 14 are protruded so that it is possible to get on and off the tractor by placing one's feet on the steps 14 and 14 whose upper, front, rear, left, and right sides are exposed, and also to allow a sitting position. Rectangular frame-shaped support frames 15, 15 are erected at the front ends, and the upper and lower end centers of rectangular plate-shaped hot air shielding plates 13, 13 are pivotably supported on the upper and lower sides of each support frame 15, 15. , by swinging the hot air shielding plate 13 around the same pivot point, the support frame 1
The ventilation hole 16 formed in the step 5 can be closed and opened, and the hot air shielding plate 13 can partially open the ventilation hole 16 to draw the heat radiated from the prime mover section 2 to the foot area of the operator placed on the step 14. A structure for installing hot air shielding plates on tractors.
