A stable and light tillage machine

Abstract

The invention discloses a stable and portable mini-tiller. The tiller includes a machine frame, a handle, a prime motor, a gear case, drilling knives and walking wheels. Two walking wheels are provided and connected through an axle. The gear box is installed on the axle through a supporting shaft; the prime motor is fixedly connected with a back box body, an output shaft of the prime motor is connected with a worm shaft through a coupling. The worm shaft penetrates through the gear box; a turbine is arranged in the gear box and sleeves on the axle. A driving gear and a driven gear are installed in the gear box, the driving gear sleeves on the worm shaft. Two drilling knives are provided; the rear end of a knife back is connected with worm shaft through the coupling, the rear end of the other knife back is connected with the front end of the supporting shaft through the coupling. The tillage is more stable and faster by using the mini-tiller; the angel adjustment of the drilling knives is convenient and quick. The tiller has the advantages of convenient operation, time and labor saving and high farming efficiency.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a stable and portable tillage machine. Background technique [0002] The farmland needs to be plowed before sowing. There are two main tillage methods in the plowing process of existing micro tillage machines: one is plowing and the other is rotary plowing. The advantages of plowing are deep plowing layer and thick live soil layer , can turn the fertilizer sprinkled on the ground below the ground, so that the plowed farmland can have good water solubility and strong stamina; but the plowed farmland has more large clods and less broken soil, and the soil surface Unevenness has a certain adverse effect on the germination and growth of crops. The rotary tiller has the opposite characteristics to the ploughshare, that is, the plowing layer is shallow, the soil is fine, the plowed farmland has a lot of broken soil, the soil surface is flat, and the fertilizer is evenly distributed; but beca...

Problems solved by technology

[0005] 2. Rotary tillage: It is not easy to adjust the tillage depth. The cutter makes the rotating wheel a polygonal shape. Therefore, when the machine is working, there are large vibrations in the front, rear, up and down, which consumes more physical strength of the operator; if it encounters a large resistance suddenly, the cutter slips, Can only raise the machine body to adjust the cutting depth

[0006] This not only brings great inconvenience to farming, but also consumes a lot of energy, and the farming efficiency is also low.
