Improved rotary tiller with gas fuel tank engine

Abstract

The invention relates to an improved rotary cultivator with an engine provided with a fuel gas and fuel tank. The improved rotary cultivator comprises a rotary cultivator body and a wide-breadth horizontal mini-tiller, wherein the rotary cultivator body is provided with a miniature propane fuel tank and is driven by a four-stroke engine; the wide-breadth horizontal mini-tiller is provided with a blade protection plate and has the function of eliminating middle missed ploughing by combination of a guide wheel and a lift-throwing type moldboard plough. The invention also relates to a rotary cultivator adopting multiple safety measures. A safety resistance fork wheel is unlikely to incline and easy to guide, and a movable protection plate is a detachable plate; the safety is further improved by means of an external protection plate assembly, and the rotary cultivator can bounce up after being pressed and deformed since a function wave external protection plate is adopted, and the function wave external protection plate has the effects of wide breadth, vibration attenuation and multi-point balance; the rotary cultivator is provided with the blade protection plate and has the effect of eliminating the middle missed ploughing by the combination of the guide wheel and the lift-throwing type moldboard plough. Fuel gas is adopted to realize noise reduction and emission reduction. The emission of carbon dioxide and hydrocarbon is reduced, so that particle effluents are improved and the emission of oxynitride is reduced. Since the fuel gas is used, the toxicity of harmful effluents is lower than that of gasoline for combustion use. The emission effect of the fuel gas in a heating turbine is superior to that in a gasoline engine within 40 seconds, so that the safety of the complete machine is good. The fuel gas and fuel tank is easy to replace.

Description

Technical field [0001] The invention relates to an agricultural and animal husbandry machine, belonging to the technical field of rotary cultivators, and is an improved rotary cultivator with a gas fuel tank engine, which includes a four-stroke engine driven rotary cultivator with a micro propane fuel tank and a belt A wide-width horizontal mini-tiller with a blade guard disc with a guide wheel and a channel-type plow to eliminate the middle and miss tillage, and also relates to a rotary tiller with multiple safety measures. Background technique [0002] People rely on food as their heaven; in farming, the more important work is plowing the land. The traditional employment of people or cattle as the main labor is not only labor intensive, but also extremely inefficient. For the land, especially for the hills and mountains, the continuous development and improvement of a variety of rotary tillers play a very important role in reducing farmers' labor intensity and improving efficie...

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
