BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover structure for a mobile agricultural machine in which an engine is mounted on a front part of a machine body and a hood (cover) for covering the engine part is detachably provided.

[0002]

2. Description of the Related Art Conventionally, there has been known a riding type mobile agricultural machine having an engine mounted on a front portion of a fuselage and a detachable hood (cover) for covering an engine portion. No. 6,086,045. And this bonnet is mainly for engine maintenance,
It can be opened for inspection and maintenance.

[0003]

[Problems to be Solved by the Invention] As described above, the bonnet (cover) of the conventional mobile agricultural machine requires maintenance of the engine part,
The bonnet (cover) itself did not have any functionality, only to be attached and detached during inspection and maintenance. In particular, it is difficult to inject engine oil into the engine by putting a hand in a narrow part, removing a screw plug of the oil inlet with a tool, and injecting oil into the oil inlet. The present invention has been made to solve the above problems.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a mobile agricultural machine having an engine mounted on a front part of a body thereof and a detachable hood covering an engine part. A headlight is attached to the hood so that it moves together when the hood is attached and detached.A recess is formed in the cover below the hood to match the lower shape of the headlight, and this recess is used to lubricate the engine. It is characterized in that it is configured to be used.

[0005]

According to the above construction, the cover structure of the mobile agricultural machine of the present invention is formed on the cover below the hood.
Since the operation of lubricating the engine can be performed from the concave portion corresponding to the lower shape of the headlight, the lubrication plug of the engine can be easily removed from the concave portion and attached. In addition, a funnel or the like can be inserted into the lubrication port from which the lubrication plug has been removed, so that the engine oil can be smoothly lubricated. Further, the lubrication can be performed by directly inserting the lubrication nozzle or the like into the lubrication port without using a funnel or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be specifically described below with reference to the accompanying drawings. In FIG. 4, a riding type rice transplanter (moving agricultural machine) 1 to which the present invention is applied includes an engine 5
To form the traveling vehicle body 6. This traveling body 6
At the rear part, a seedling planting section 8 is mounted via a lifting link 7 composed of a parallel link, a hydraulic cylinder and the like. A transmission case 9 is provided on the traveling vehicle body 6 obliquely below and behind the engine 5, and power is transmitted from the engine 5.
The speed is changed and the front wheel 2 and the rear wheel 3 are driven to drive and travel. At the same time, power is transmitted to the seedling planting unit 8 via the working unit transmission shaft 10 so that the seedling transplanting operation is performed. I have.

The traveling vehicle body 6 is provided with a steering column 11 and a steering handle 12 located above the transmission case 9.
And a clutch pedal (not shown) used when the main shift lever, the auxiliary shift lever, the working unit shift lever, the main shift lever and the auxiliary shift lever are turned on and off, not shown, near the steering handle 12. , A brake pedal and the like are provided. A detachable hood 13 that covers an engine room accommodating the engine 5, a lower cover 14 disposed below the hood 13, and an intermediate portion between the hood 13 and the lower cover 14 are provided at the front of the fuselage. The installed headlight 15, bumper 16, and the like are provided. A driver seat 17 is provided behind the steering handle 12, and a lifting lever 18 for operating the lifting link 7, an adjustment lever (not shown) for adjusting the seedling planting part 8 is provided on a side of the driver seat 17. Is provided.

As shown in FIGS. 1 to 3, the headlamp 15 is attached to the bonnet 13, and when the bonnet 13 is removed, the headlamp 15 also comes off, and electricity is supplied from the lead wire 15a. It can be used as work lighting. The lower cover 14 includes:
A semicircular headlight housing recess 19 for housing the lower portion of the headlight 15 is formed, and the headlight housing recess 19 is opened when the hood 13 and the headlight 15 are removed. It has become. A screw plug 20 for opening and closing an injection port for injecting engine oil is provided below the engine 5 so as to correspond to the headlight housing recess 19. Also, from the oil pan below the engine 5,
The oil drain pipe 21 projects forward and the body frame and the bumper 1
6 and bends downward, with a screw plug 2
1a is provided. The screw plug 21 a protrudes slightly downward from the lower edge of the lower cover 14.

When the engine oil is injected into the engine 5, the screw plug 20 is easily inserted with a tool by inserting a hand from the position of the headlight accommodating recess 19 with the hood 13 and the headlight 15 removed. It can be removed and attached. The engine oil can be injected by inserting a funnel 22 or the like into the lubrication port from which the screw plug 20 has been removed.
Further, the lubrication can be performed by directly inserting the lubrication nozzle or the like into the lubrication port without using a funnel or the like. When the engine oil becomes dirty and is discharged, the screw oil 21 can be discharged from the oil drain pipe 21 by removing the screw plug 21 a projecting slightly downward from the lower end edge of the lower cover 14.

In the riding type rice transplanter (moving agricultural machine) 1 having such a configuration, when the riding type rice transplanter 1 performs a seedling transplanting operation, the front wheel 2 and the rear wheel 3 of the traveling vehicle body 6 are driven to cover the field. The seedling planting section 8 that travels and receives power via the working section transmission shaft 10 performs seedling planting work. When the engine oil of the engine 5 becomes low or when the oil is to be injected for replacement, the bonnet 13 and the headlight 15 are first removed, and
The screw plug 20 is removed with a tool by inserting a hand from the position 9 and a funnel 22 or the like is inserted into an oil inlet, and engine oil is injected. Also, the lubrication can be performed by directly inserting the lubrication nozzle or the like into the lubrication port without using a funnel or the like.
When discharging the engine oil for replacement, the screw plug 21a is removed and the oil is discharged from the oil drain pipe 21. In addition, maintenance of engine parts at night or in dark places such as indoors,
When performing inspections and maintenance,
The headlight 15 can be removed and the headlight 15 can be used as work lighting.

Next, the embodiment shown in FIGS. 1, 5 and 6 will be described. Between the vehicle body frame 23 of the traveling vehicle body 6 on which the engine 5 is mounted and the transmission case 9, a reinforcing stay 24 is fixed diagonally by bolts 25 and 26, and the vehicle body frame 23 is reinforced. A hydraulic pump 27 is provided on the side of the transmission case 9, and a belt 28 is wound between an input pulley 27 a and an output pulley 5 a of the engine 5, and a tension pulley 29 for applying tension to the belt 28 is Tight arm 30
Supported by The base of the tight arm 30 is pivotally supported by the bolt 25. A spring support member 31 protrudes from the tight arm 30 to the opposite side, and between the spring support member 31 and the reinforcing stay 24 near the bolt 26,
A tension spring 32 whose spring pressure is adjustable is stretched.

In the second embodiment constructed as described above, a tight arm 30 of a tension pulley 29 for applying tension to a belt 28 for transmitting power from the engine 5 to a hydraulic pump 27 and a bolt 25 of a reinforcing stay 24 are used. And the tension spring 32 is also stretched using the bolt 25 and the reinforcing stay 24,
In order to support the tight arm 30 and the tension pulley 29, there is no need to prepare a separate supporting member, and the configuration is simplified, and the device can be manufactured compactly and at low cost.
