[0002]
[Prior art]
2. Description of the Related Art Conventionally, farm vehicles such as agricultural tractors have an engine mounted on the front of a vehicle body, and the upper or side thereof is covered with a bonnet, and the front is covered with a front grille. Or the side of the engine is covered with a side cover separate from the bonnet.
These bonnet, side cover, and front grill covers are configured to be detachable for maintenance of the engine and its peripheral equipment, or are configured to be rotatable about a part of the hood to open the surroundings of the engine It is configured as possible.
Especially for the front grill, it is necessary to attach, detach, and open the radiator and battery installed in front of the engine and the headlights attached to the front grill itself. In this method, a handle is protruded below the side of the front grill and the front grill is configured to be detachable by rotating the handle. Alternatively, as disclosed in JP-A-4-11583, There has been known a configuration in which the fixture is released by twisting the provided marker and handle to either the left or right.
[0003]
[Problems to be solved by the invention]
However, when a handle or marker, which is a fixed unlocking tool for the front grill of a farm vehicle as described above, is projected outside the bonnet and runs through an orchard or grass group, branches such as fruit trees get caught in these and crops are grown. Since there was a problem that it was damaged or weeds were entangled with each other and it was difficult to wash the car, it was desired that the covers were as uneven as possible.
[0004]
[Means for Solving the Problems]
In order to solve such problems, the present invention has taken the following technical means.
That is, in an agricultural vehicle in which an engine 1 is provided at the front of the vehicle body, the upper and side portions of the engine 1 are covered with a bonnet 2 (43) , and the front of the engine 1 is covered with a front grill 3 .
While a single fixed rod 33 is supported on the inner upper portion of the front grill 3, projections 35, 35 that fit into recessed portions 34, 34 formed on the vehicle body side are provided on the left and right sides of the lower surface of the grill 3,
A single rod 27 spanning the left and right widths is rotatably supported on the inner left and right sides of the bonnet 2, and hooks 28 and 28 for locking the fixed rod 33 at two left and right portions of the rod 27 are used as springs 30. Further , an opening 4 having an opening / closing lid 23 is provided on the surface of the bonnet 2, and the opening 4 extends from the left and right ends of the rod 27 and the hooks 28, 28 are provided. A front grill attachment / detachment device for agricultural vehicles is characterized in that the lever portion 26 to be rotated is exposed .

【Example】
Problems to be solved and means for solving the problems of the present invention are as described above, and an embodiment will be described for an agricultural tractor (hereinafter referred to as a tractor).
The overall structure of the tractor 10 will be described. Tractor 10, the clutch housing from the engine 1, the transmission case, and a main frame 11 which is integrally connected to Li Ya transmission case or the like as a vehicle body of the rigid main section, the front wheel 12, front to the right and left of the main frame 11 12 and a pair of left and right rear wheels 13 and 13 are provided at the rear of the main frame 11, and the rotational power of the engine 1 in the bonnet 2 is appropriately decelerated in the transmission case and transmitted to the front wheels 12 and 12 and the rear wheels 13 and 13. And is configured to travel. Further, the front wheels 12 and 12 are rotated by a turning operation of a handle 14 provided behind the bonnet 2. A floor 15 is provided above the central portion of the main frame 11. A handle 14 is provided above the front portion, and a seat 16 is provided above the rear portion. A hanger weight 17 is provided in front of the engine 1, and a radiator 18 and a battery 19 are placed on the hanger weight 17.
[0006]
The bonnet 2 covers from the upper front of the radiator 18 to the rear of the engine 1 along with its peripheral devices, and a meter panel 20 and foot covers 21 and 21 are provided at the rear end. On the upper surface of the bonnet 2, a rectangular opening 4 is opened at the position of the water supply cap 22 of the radiator 18, and a lid 23 is provided on the opening 4. The lid 23 has a shape along the shape of the upper surface of the bonnet 2, and a knob 24, 24 is provided at the center, and the fulcrum 25 can be opened with the knob 24, 24. ing. An opening lever 26 that is a fixing release tool R of the front grill 3 protrudes from the side in the opening 4. The tip of the lever 26 is connected to one end of a rod 27 that is rotatably supported over the width of the bonnet 2 on the left and right inner sides. The rod 27, two left and right hooks 28, 28 projecting from the front surface of the hood 2 is provided. The hook 28 is configured such that when a forward pressing force is applied to the lever 26, the hook 28 is pushed downward about the rotation fulcrum 29, and when the pressing force disappears, the hook 28 is returned to its original position by the urging force of the spring 30.
[0007]
The front grill 3 is provided with a headlight 31 in the upper part of the front surface and mesh-shaped ventilation portions 32 and 32 in the middle of the front surface. Further, the overall cross-sectional shape viewed from above is a substantially “U” shape so as to cover the periphery of the battery 19 placed on the hanger weight 17. Fixed rods 33 are provided on the left and right sides of the front grill 2 behind the headlight 31. Further, on the lower surface of the front grill 3, four protrusions 35, 35 are provided on the front and rear and the left and right according to the positions of the recesses 34, 34 provided on the hanger weight 17. -It is configured to fit 35 and fix the lower part.
[0008]
When mounting the front grille 3, first, the lower projections 35, 35, 35 and 35 are placed in accordance with the positions of the recesses 34, 34, 34 and 34 provided in the bumper weight, and the front grille 3 is placed on the bonnet. 2 is pushed, the fixed rod 33 comes into contact with the inclined surface 28a of the front surface of the hooks 28, 28. When the push rod is further pushed, the fixed rod 33 overcomes the urging force of the spring 30 and pushes the hooks 28, 28 downward. Thus, the fixing rod 33 falls into the scratched portion 28b, and the spring 30 pulls up the hooks 28 and 28 to fix the front grill 3 .
[0009]
When the front grille 3 is removed, the cover 23 is opened, the lever 26 is pushed forward, and the front grille 3 is moved forward, so that the hooks 28 and 28 are released and can be removed.
As another example of the opening 4, it is conceivable to provide the opening 4 on the side of the bonnet 2.
[0010]
An oil filler 40 and an oil filler cover 41 are provided at the rear of the upper surface of the bonnet 2.
The configuration of the fuel filler cover 41 will be described. The fuel filler cover 41 is a plastic plate and is attached to the front of the fuel filler 40 across the left and right width of the bonnet 2. The cover portion 41 a of the fuel filler cover 41 is inclined toward the upper surface of the fuel filler port 40, and forms a flat portion on the upper surface of the fuel filler port 40. The bottom surface of the filler opening cover 41 has a shape that is gently curved in accordance with the shape of the left and right width of the bonnet 2, and the insulator 42 is sandwiched between the contact surfaces of the bonnet 2. The left and right ends of the filler opening cover 41 are formed with key portions 41b along the fixing grooves of the side cover 43. When the filler opening cover 41 is attached, the side cover 43 is once removed, and the key portion 41b. Fix by tightening the side cover together.
As a result, the fuel filler cover 41 can be easily attached as necessary, and the plants flowing along the bonnet 2 are caused to flow rearward along the fuel filler cover 40 without being caught by the irregularities of the fuel filler 40. It has become.
As another example of the fuel filler cover 41, it is conceivable that the cover portion 41 is configured upright. Thereby, the probability that the vegetation flowing along the bonnet 2 flows toward the worker is lower than that in the case of the shape of the slope.
