It relates to a dust-proof apron in a tractor that prevents

[0002]

[Prior Art]

 Conventionally, when installing a mower on a tractor and performing mowing work, the grass and sand dust blown up by the wind blown from the midmore adheres to the front grille of the bonnet and the intake ports of the side covers, blocking intake to the radiator. However, there was a problem that the engine overheated. For this reason, there was a problem that the work had to be stopped frequently and the intake port of the front grill and the side cover had to be cleaned.

[0003]

[Problems to be solved by the present invention]

 The present invention has been made in view of the above conventional problems, and an object thereof is to improve the problems.When a large amount of dust is soaring by a tractor, the soaring dust is generated by the front grille and the side of the bonnet. It is intended to provide a dustproof apron for a tractor that prevents the engine from overheating due to being blocked by the intake air of the cover and obstructing the intake of air to the radiator.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms a recess that surrounds the lower part of the bonnet from the front grille on the front of the hood of the tractor to approximately the front half of the left and right side covers, and the left and right rear ends are curved upward at an obtuse angle. The back surface of the concave apron in plan view is attached to the front bumper of the tractor through a hinge, and a detachable locking member that locks the apron in a horizontal position is provided to keep the apron horizontal. It features a dustproof apron for a tractor that can be converted into a locked posture and an inverted posture.

[0005]

[Action]

 When a large amount of dust is flying up with a tractor, the dust apron is locked in a horizontal position, so that dust that rises from the ground is blocked by the dust apron at the bottom of the bonnet, and the front grille and side covers are inhaled. The intake air from the front grille and the side cover is taken in from the air intake port of the radiator, and the engine is prevented from overheating. In addition, the dust-proof apron locked in a horizontal position acts as an over bumper, and in the case of land conditions where it is not possible to get on and off the driver's seat directly from the ground, use this dust-proof apron as a step instead of the ground with good feet. You can get on and off the driver's seat along with the dust-proof apron and tires.

【Example】

 Hereinafter, the present invention will be described in detail with reference to an embodiment shown in the drawings. FIG. 1 is a front side view of a tractor adopting the present invention during mid-mower work, and FIG. 2 is a front plan view of the tractor. In the figure, 1 is the hood of a tractor accommodating equipment such as an engine, 2 is the driver's seat of the tractor, 3 is the front grill on the front of the bonnet, 4 is side covers on the left and right sides of the bonnet, 5 is a side cover intake port due to punching, Reference numeral 6 denotes a frame-shaped front frame that supports the engine and other equipment, and also swingably supports the front wheel shaft 8 of the drive front wheel 7, and 9 is attached to the front end surface of the front frame 6 via a bracket 10. The bumper 11 is a dustproof apron according to the present invention attached to the bumper 9. The dustproof apron 11 has a recess 11a that surrounds the lower part of the bonnet 1 from the front grill 3 on the front of the bonnet 1 to approximately the front half of the left and right side covers 4 and 4. The left and right rear end portions 11b and 11b are directed upward at an obtuse angle. It is made of a curved steel plate or a punching metal plate material 12 in plan view, and a string-like sealing material 13 that closes the gap with the periphery of the bonnet 1 is attached to the back surface along the recess 11b, and the outer circumference is a pipe. The front grille 3 is reinforced by edge members 14 and the like, and the flat portion in front of the front grill 3 is reinforced by rectangular rib members 15 in the machine width direction. As shown in FIGS. 3 (A) and 3 (B), the dust-proof apron 11 has a mounting plate 17 attached to the lower surface of the rib material 15 via a hinge 16 and fixed to the front surface of the bumper 9 with bolts 18 so as to be horizontal. The ribs 15 are attached to the back and back of the ribs 15 while being tiltably attached to the posture and the posture inverted to the front, and attached to the upper surface of the bracket 19 fixed to the back side of the bumper 9 by a detachable locking member 20 formed of an elastic piece or the like. The dust-proof apron 11 is held in a horizontal posture by locking a rod-shaped engaging member 21 which protrudes to the side.

Reference numeral 22 in FIG. 1 denotes a midmower mounted between the front and rear wheels of the tractor 1. A large amount of dust such as grass cuttings and sand dust indicated by an arrow line that rises up during the midmower work is under the front grill 3 of the bonnet 1. The dust-proof apron 11 locked in a horizontal position does not reach the front grill 3 and the intake port 5 of the side cover, and the intake air to the radiator passing therethrough is secured to prevent the engine from overheating. When the plate material 12 of the dustproof apron 11 is a steel plate, dust is blocked by the bottom surface of the steel plate, and when the plate material 12 is punched metal, grass is caught in the eyes of the punching metal and the eyes are clogged. Dust is prevented from adhering to the intake port 5 of the cover. When the side cover 4 needs to be opened, the side cover 4 can be opened only by raising the dust-proof apron 11 forward, and the dust attached to this can be removed by raising the dust-proof apron 11 upside down. In addition, the dust-proof apron 11 locked in a horizontal position acts as an over bumper and, in the case of land conditions where it is not possible to get on or off the driver's seat directly from the ground, use the dust-proof apron 11 as a step instead of the ground with good feet. It is possible to get on and off the driver's seat 2 along with the dust-proof apron 11 and the driving front wheels 7.

FIGS. 4 and 5 show a plan in which a vertical dustproof screen 23 for covering the intake ports 5 of the left and right side covers from the front grill 3 is additionally provided on the dustproof apron 11. The dust soaring above adheres to the dustproof screen 23, but since the area of the dustproof screen 23 is much larger than the area of the front grill 3 and the intake port 5 of the side cover, the dust blocks the entire surface of the dustproof apron 11. Therefore, an intake area larger than the area of the front grill 3 and the intake port 5 of the side cover is secured, and overheating of the engine is prevented.

[0009]

[Effect of the device]

 As described above, the dustproof apron of the tractor of the present invention forms a recess that surrounds the lower part of the bonnet from the front grill on the front of the bonnet of the tractor to the approximately front halves of the left and right side covers, and the left and right rear ends are upwardly obtuse angled. The rear surface of the concave apron curved in plan view is attached to the front bumper of the tractor via a hinge, and a detachable locking member for locking the apron in a horizontal position is provided. Since it can be switched between a horizontally locked posture and an inverted posture, the dust apron can be lifted from the ground by locking the dust apron in a horizontal posture when performing work such as a large amount of dust rising on the tractor. Dust is blocked by the dust-proof apron at the bottom of the bonnet and does not reach the intake openings of the front grill and side covers. The intake air of the radiator that is taken in from the intake port of the door cover is secured to prevent the engine from overheating, and due to the large amount of dust that has conventionally blown up, the work is frequently stopped and adheres to the intake ports of the front grill and side covers. The labor of cleaning the dust is greatly saved, and the work efficiency is improved. In addition, the dust-proof apron locked in a horizontal position acts as an over bumper, and in the case of land conditions where it is not possible to get on and off the driver's seat directly from the ground, use this dust-proof apron as a step instead of the ground with good feet. The dust-proof apron and tires allow passengers to get in and out of the driver's seat, which is extremely useful in practice.
