Description

Mowing machine

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a passive type minicar machine having a toasting stand and a drill hole for continuous drilling.

For example, in this kind of submersible machine equipped with a gasoline engine, a fuel tank is generally disposed on the upper part of the engine. However, as the engine becomes larger, the capacity of the fuel tank becomes larger as the engine becomes larger. Not only can not be finished, but also the problem is that the stability of the gas is bad and the front clock is worsened. In addition, when one breeder is installed on the upper surface portion of the fuel tank to discharge the expanded air in the tank, when the tank is tilted in a state where the breather side is at a low position and the air trapped at the high position side of the tank is expanded, There is a risk of fuel being charged.

Therefore, according to the present invention, the fuel tank of the engine is disposed below the gas step, and a concave tank bottom cover is provided outside the bottom of the fuel tank, so that even if the fuel tank has a large capacity, the surplus space below the gas step The fuel tank and the fuel hose are prevented from interfering with the surface of the fuel tank by the tank bottom cover to improve the durability of the fuel tank and the fuel hose.

In addition, the tank bottom cover is inserted into the fixed pipe of the machine frame and the cover is fixed with a single bolt to the machine frame, so that the tank bottom cover can be easily separated, It is easy to check maintenance.

Further, the fuel tank of the engine is installed below the gas staff, and the front and rear breeders are provided at the remote positions before and after the fuel tank oil filler so that the air evaporatively inflated in the fuel tank, even if the gas is inclined back and forth, So that the fuel is prevented from leaking out of the breather naturally.

In addition, the breather pipe is connected to the breather in such a manner that the breather pipe is continuously connected to the breather pipe, and the breather pipe is supported upwardly in an inverted V shape so as to prevent leakage of fuel from the breather even if the gas is greatly inclined back and forth, It makes reservoir possible.

[

On the other hand, one end side of the breather pipes 92 and 93 is connected to the breeders 72 and 73, and the intermediate part of the breather pipes 92 and 93 is lifted upwards in an inverted V- 46 to the right side of the bonnet right attaching frame 94 and the middle portion of the breather pipes 92, 93 is folded on the hook 95 so that the middle portion of the breather pipes 92, The hook 95 is installed at a position where the fuel liquid level in the tank 40 is not higher than the lift height C of the breather pipes 92 and 93 even when the gas is inclined by more than 30 degrees in the forward and backward directions So as to prevent the fuel from leaking from the breather pipes (92, 93).

The fuel tank 40 is provided at a lower position below the front step 63 on the side of the engine 2 and the fuel tank 40 is provided on the opposite side to the muffler 41, The fuel tank 40 and the muffler 41 are disposed on the right and left sides of the engine 2 with the fuel tank 40 being lower than the upper surface of the engine 2 and the engine 2 or the muffler 41 The fuel tank 40 and the fuel tank 40 are prevented from being heated to a high temperature so that bubbles are generated in the fuel inside the vaporizer and the fuel is not properly supplied. The muffler 41 or the like is disposed at a lower center in the front side so as to improve the balance between the front and rear parts of the rear planting part 15 and to stabilize the gas and to increase the installation height of the fuel supply cap 84 of the fuel tank 40 By substantially matching the height of the top surface of step 63, It does not harm the fuel tank (40), well protected in step 63 and will be in addition to the obvious prevalence backless leaking oil when refueling the fuel tank (40), one easily.

It is also possible to prevent the surface of the tank 40 from interfering with the bottom of the tank 40 by the cover 86 when the tank 40 is put in or out of the tank by the tank cover 86 provided outside the bottom of the tank 40, The fuel hoses 79 and 80 connected to the hoses 79 and 80 are also safely protected by the cover 86 to prevent accidental breakage or breakage of the hoses 79 and 80, have.

Further, the cover 86 can be attached and detached by one operation of the bolts 91, thereby facilitating the maintenance and inspection around the bottom of the tank 40, thereby improving maintenance.

Even when the gas is inclined in the forward and backward directions during the operation, the evaporated and expanded air in the tank 40 is rapidly discharged out of the tank from either the front or rear two breeders 72 or 73 and the breather 73 ) Or leaking of fuel from the breather 72 can be reliably prevented. In this case, even if the lean angle is more than 30 degrees, for example, it is possible to reliably prevent fuel leaking by the breather pipes 92, 93 have.

The fuel tank 40 of the engine 2 is installed below the gas step 63 and the tank bottom cover 86 having a concave shape outside the bottom of the fuel tank 40 Even in the case of, for example, the fuel tank 40 having a large capacity, the surplus space below the gas step 63 can be effectively used to provide a low center of gravity and a compact structure to improve the stability of the gas, The tank bottom cover 86 prevents the fuel hose 40 and the fuel hose from interfering with the surface of the fuel so as to improve their durability.

The tank bottom cover 86 is inserted into the fixed pipe 88 of the machine frame machine frame 3 and the cover 86 is fixed to the machine frame frame 3 by a single bolt 91 The maintenance of the fuel tank 40 and the oil-filled portion can be easily performed by removing the tank bottom cover 86. Thus, the maintenance performance can be improved.

The fuel tank 40 of the engine 2 is disposed below the gas step 63 and the front and rear breeders 72 and 73 are installed at front and rear remote positions of the oil supply port 71 of the fuel tank 40 The air that has evaporated and expanded in the fuel tank 40 is discharged from the one of the breather 72 and 73 to the outside of the tank 40 so that the fuel naturally leaks from the breaders 72 and 73 And the like.

Further, by connecting the breather pipes 92 and 93 to the breather pipes 72 and 73 in a communicative manner and supporting the breather pipes 92 and 93 upwardly in an inverted V-shape, even when the gas is greatly inclined back and forth, It is possible to prevent the fuel from leaking from the fuel tank 92 or 93 and to securely store the fuel in the tank 40.
