Improved rotary cultivator adopting engine provided with gas fuel tank and extruded tank method

Abstract

The invention provides an improved rotary cultivator adopting an engine provided with a gas fuel tank and an extruded tank method, and relates to a rotary cultivator with multiple safety measures. The improved rotary cultivator comprises a rotary cultivator which is driven by a four-stroke engine provided with a minitype propane fuel tank as well as a horizontal wide mini-tiller which is provided with bladed protecting plates and eliminates middle tillage missing through matching of a guide wheel and a lift-throwing type plough. With the adoption of an outer protecting plate assembly, the safety is further improved, and further, the outer protecting plate assembly adopts outer protecting plates with function waves, so that the outer protecting plates are bounced through compression deformation and have the wide damping and multi-point balance functions; the mini-tiller adopting matching of the guide wheel and the lift-throwing type plough and provided with the bladed protecting plates has the function of middle tillage missing elimination; fuel gas is adopted for noise reduction and emission reduction; toxicity of harmful emissions of the fuel gas is lower than that of harmful emissions of burning gasoline; the emission of the fuel gas within 40s after starting and the emission of the fuel gas during warming-up are superior to the emission of a gasoline engine, and the safety of the whole machine is good; the gas fuel tank is easy to replace. According to the extruded tank method, extrusion is performed by introducing high-pressure oil having pressure difference with the pressure at the front part and pressure at the rear part of a prefabricated tank into a prefabricated pipe of a forming die, and the slightly higher pressure difference at the rear part is required due to front and rear edge losses and radians.

Description

technical field [0001] The invention relates to an agricultural and animal husbandry machine, which belongs to the technical field of rotary cultivators, and is an improved rotary cultivator with a gas fuel tank engine and a can making method, which includes a four-stroke engine-driven rotary cultivator with a miniature propane fuel tank. The invention relates to a cultivator and a wide-width horizontal micro-cultivator with a guide wheel for a blade guard plate and a shifting type plow to eliminate missing tillage, and also relates to a rotary tiller with multiple safety measures. 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 imp...

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
