The propeller shaft 52 extends below the tank 24 in the front-rear direction, and transmits rotational power from the gear transmission 44 to the differential device 54. The differential device 54 also contains a predetermined amount of lubricating oil inside, and there is a risk of oil exposure.

FIG. 2 is a perspective view of the oil receiving bucket 56.
The oil receiving bucket 56 has a front plate 14 cut away, and a horizontal plate portion 58 that covers a portion from below the driver's seat 20 and the driving power chamber 22 to almost the front half of the tank 24, and a propeller shaft.
The propeller shaft 52 has an inclined portion 60 that covers the rear end of the rear end 52 and the lower portion of the differential device 54 and is inclined at an inclination angle substantially equal to that of the propeller shaft 52. The vertical wall 62 extends along the peripheral edges of the horizontal plate portion 58 and the inclined portion 60, and stands upright so that the upper surfaces are aligned at the same height. The oil sump 64 is formed by the inclined portion 60 and a portion of the vertical wall 62 rising from the periphery of the inclined portion 60, and is the lowermost portion of the oil receiving bucket 56 at the rear end. Drain 66
Is provided at the lowermost part of the vertical wall 62 forming the side wall of the oil reservoir 64, and is opened and closed by the cap 68 from the outside. A total of three projecting portions 70 are provided at the left and right of the front end of the vertical wall 62 and at the center of the rear end of the vertical wall 62, and are aligned with the height of the upper surface of the vertical wall 62, and project from the vertical wall 62. I have. In the oil receiving bucket 56, the upper surface of the overhang portion 70 is applied to the lower surface of the frame 12, the bolt 72 is inserted through the insertion hole of the overhang portion 70 from below, and is removably fixed to the frame 12 by the bolt 72.

Oil-using equipment using oil, such as a plunger pump for intermittently discharging high-pressure liquid using an intermittent discharge stroke and an engine for driving the plunger pump, is also provided in the injection machine power chamber 28. Exists. These injection machine power rooms
The oil-using equipment in the oil sump 64 is arranged in a concentrated manner above the oil sump 64, so that oil leaks and drops from the oil-using equipment in the injection machine power chamber 28 are received in the oil sump 64.

If it is difficult to centrally dispose the oil-using equipment such as a plunger pump in the injection machine power chamber 28 above the oil sump 64, a horizontal plate similar to the horizontal plate portion 58 is provided behind the inclined portion 60. The section may be extended to cover the entire lower part of the injector power chamber 28, or to cover only the lower part of the main oil-using equipment in the injector power chamber 28 such as a plunger pump.

The operation of the embodiment will be described. The lawn high-pressure liquid injection vehicle 10 lowers the post 38 of the high-pressure liquid injection machine 26 to a lower position, and runs on the lawn 74 at a low speed. Injector power room
The plunger pump 28 inhales the spray liquid in the tank 24 and intermittently discharges the spray liquid at a high pressure through an intermittent discharge stroke. Is injected intermittently. In this way, the spray liquid is turf 74
It is injected while forming a vertical through hole having a predetermined depth.
The crushing roller 36 crushes the turf 74 raised by the high-pressure injection and injection of the spray liquid.

During running, HST42 and oil cooler
If oil leaks from equipment using oil such as 46,
The oil that falls due to leakage from the oil-using equipment in the power chamber 20 and the traveling power chamber 22 flows to the horizontal plate portion 58, and the oil that falls due to leakage from the oil-using equipment in the differential unit 54 and the injector power chamber 28. Then, the oil coming down from the propeller shaft 52 along the propeller shaft 52 and falling from the propeller shaft 52 is received and stored in the inclined portions 60, respectively, and is prevented from falling onto the lawn 74. The oil received by the horizontal plate portion 58 flows toward the oil sump 64 by gravity,
Collects in oil sump 64. When discharging the leaked oil from the oil receiving bucket 56, the cap 68 is removed and the oil is transferred from the oil receiving bucket 56 to a container such as a bucket.

For maintenance and inspection of the equipment in the traveling power chamber 22, the bolt 72 is loosened and the oil receiving bucket 56 is removed from the frame 12, and after the work is completed, the oil receiving bucket 56 is again attached to the frame 12. Install it.

Although the high pressure liquid injection vehicle 10 for turf has been described as an embodiment, the turf traveling vehicle of the present invention can be applied to other vehicles that travel on turf for a predetermined work.

[0025]

According to the first aspect of the present invention, the oil receiving cover receives and leaks the oil leaking from the oil-using equipment storage chamber and storing the oil, thereby causing the oil leaking from the lawn traveling vehicle. Turf damage can be prevented.

According to the second aspect of the present invention, the oil receiving cover receives and leaks oil that leaks and falls from the oil-using equipment such as the power room for driving and the hydraulic drive device of the driver's seat, and stores the oil. Damage to the turf due to oil leaking from the traveling vehicle can be prevented.

According to the second aspect of the present invention, the driving power room and the driver's seat are arranged at the front of the lawn traveling vehicle, and the oil receiving cover is used to share oil leaking from the driving power room and the driver's seat. Oil can be efficiently received by the oil receiving cover.

According to the third aspect of the present invention, since the oil receiving cover is detachable, maintenance of the oil-using equipment can be performed without any trouble by removing the oil receiving cover.

According to the fourth aspect of the present invention, the oil receiving cover also receives leaked oil falling from the propeller shaft of the turfland traveling vehicle and the rear wheel differential device, and lowers the lower portion of the rear wheel differential device. Equipped with a drain as the lower part, it is possible to efficiently discharge oil leaking from the oil receiving cover.

According to the fifth aspect of the present invention, since the lower surface of the oil receiving cover is a smooth surface without projections, even if it comes into contact with a partial raised portion of the turf while the turf traveling vehicle is running. It can prevent scratching and damaging the turf.
