Mini-tiller using four-stroke engine with miniature propane fuel tank

Abstract

The invention discloses a mini-tiller using a four-stroke engine with a miniature propane fuel tank. The mini-tiller comprises the four-stroke engine with the miniature propane fuel tank and a rotary tiller comprising various safety measures, wherein slime is reduced and tangled grasses are cut off by using a safety follow-up upper protective plate, a safety follow-up rear protective plate and left and right safety protective frames; no error operation is performed, high safety and the purpose of achieving the standard are realized, the observation is facilitated and the working efficiency is improved by using a folding and buckle pushing double-action security measure; a safety resistance fork wheel does not skew easily and can be easily guided; a movable protective plate is detachable, so the transportation cost can be reduced. Gas is adopted for noise reduction and emission reduction. The emission of carbon monoxide and hydrocarbon is expected to be reduced, so particle emissions are improved and the emission of the nitrogen oxide is reduced. The toxicity of harmful emissions is lower than that of combustion gasoline by the fuel. Little harmful components such as aromatic hydrocarbon exist in the emission. Since the gas does not form an oil film on the wall of a gas inlet pipeline and is not concentrated in a cold state like the gasoline, the emission within 40 seconds after start and in a heating machine is superior to that of a gasoline engine, and the safety of the entire machine is good. The fuel tank is easy to replace.

Description

technical field [0001] The invention relates to an agricultural and animal husbandry machine, which belongs to the technical field of rotary tillers, in particular to a rotary tiller with multiple safety measures, and a four-stroke engine miniature tiller with a propane fuel tank. Background technique [0002] Food is the most important thing for the people; in farming, the more important labor is plowing the fields. The traditional employment of people or cattle as the main labor is not only labor-intensive, but also extremely inefficient. For land, especially for hills and mountainous areas, the continuous development and improvement of various rotary tillers plays an important role in reducing the labor intensity of farmers and improving efficiency. Rotary cultivators are widely used in the mode of sometimes self-propelled sometimes not self-propelled by people's preferences to carry out operations. In recent years, with the rapid development of the economy and social pr...

Problems solved by technology

But, first of all, the starting handle of the existing rotary tiller, also known as the flameout handle, is opened when held, and there is no misuse protection measure. When the starting handle is accidentally pressed, the rotary knife will rotate, which does not meet the safety requirements high requirements

Secondly, the fender device of the existing rotary cultivator generally just simply arranges the fender on the top of the rotary tiller, and the fender is fixed on the body, and there are obvious deficiencies in the use process: one is because the fender Only cover the top of the rotary tiller, the dust is flying when the rotary tiller is working, the dust is large, and the working environment is poor, which directly affects the health of the operator. The third is that it is easy to stick to mud. Because the fenders of various rotary tillers are made of metal plates, the extruded soil is mixed with grass roots and sticks to the fenders firmly. Strong friction occurs, which increases power consumption and accelerates the wear of the rotary tiller. The sticky clay on the fender needs to be scraped off manually with a tool shovel, which is time-consuming and laborious and affects the efficacy. One of the reasons is that the fender It is fixed, and there are no solutions such as movable or follow-up upper fenders and movable rear fenders; the fenders are fixed, and there is a special case, which is fixed during rotary tillage operations, only It is easy to install and replace. For example, utility model 200920244006.8, a rotary tiller with an openable top cover, which consists of: the main body of the rotary tiller, which is characterized in that: the upper cover of the main body of the rotary tiller includes a The connected movable upper cover plate has a lock on the upper cover plate; the upper cover plate is fixed during operation, which is the same as the movable and follow-up upper fender and the movable rear fender during operation of the present invention. There are essential differences in solutions such as fenders and left and right protection

Fourth, it is easy to get entangled with grass during rotary tillage, that is because the fenders of various rotary tillers have no cutting edge measures

The fuel used in the gasoline engine is gasoline; the gasoline and air are used to form a combustible mixture before entering the cylinder with an air filter and a carburetor; according to the four-stroke inlet pressure explosion, the combustible mixture enters the cylinder and is compressed. Near the end of the compression, the gas is ignited and burns to expand and do work. The gasoline engine enters the cylinder with combustible mixture, and the compressed mixture is also combustible. Because gasoline and air form a combustible mixture, because the excess fuel enters the cylinder, it can only become mist in an instant. The phenomenon that part of the fuel has not been completely burned, so the fuel consumption and exhaust pollute the environment
