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...
