Walk-behind farming machine

Abstract

The invention discloses a walking type agricultural soil preparation machine. The walking type agricultural soil preparation machine comprises a frame, a walking mechanism, an engine and a gearbox, wherein a push shovel mechanism is arranged in the front of the frame; the walking mechanism comprises a left crawler-type walking wheel, a right crawler-type walking wheel and a driving axle, and the left half axle and the right half axle of the driving axle are respectively connected with driving wheels of the left crawler-type walking wheel and the right crawler-type walking wheel; the input shaft of the gearbox is connected with a main shaft of the engine through a clutch, a first output gear and a second output gear are arranged on the output shaft of the gearbox, the first output gear is connected with the driving axle, the second output gear is connected with a driving oil pump, and the driving oil pump is respectively connected to a soil preparation shovel lifting oil cylinder and a soil preparation shovel tilt oil cylinder through a high-pressure oil pipe and a hydraulic control valve; a handrail is mounted on the shell of the gearbox, and a clutch operating lever, a shift operating lever and an operating lever of the hydraulic control valve are respectively arranged on the handrail. The walking type agricultural soil preparation machine is self-powered, high in integration level and good in passing ability, and can easily walk in various landforms; moreover, the machine is simple in structure, low in cost and wide in application range.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a walk-behind agricultural land preparation machine. Background technique [0002] Existing land preparation machines are usually combined land preparation machines. This land preparation machine itself has no power. It needs to be installed behind the tractor, used together with the tractor, and moved forward by tractor traction. After the tractor is connected together, it becomes extremely long, the steering is very inflexible, the passability is very poor, and it cannot walk on narrow roads. Therefore, it can only be used in vast plain areas. [0003] On the other hand, soil preparation machines and tractors are large-scale mechanical equipment with large volume and heavy weight. In southern China and many regions in the world, rainfall is very abundant, the soil is soft and has high water content, and they cannot carry soil preparation machines and tractors at all. the ...

[0002] Existing land preparation machines are usually combined land preparation machines. This land preparation machine itself has no power. It needs to be installed behind the tractor, used together with the tractor, and moved forward by tractor traction. After the tractor is connected together, it becomes extremely long, the steering is very inflexible, the passability is poor, and it cannot walk on narrow roads. Therefore, it can only be used in vast plain areas

[0003] On the other hand, soil preparation machines and tractors are large-scale mechanical equipment with large volume and heavy weight. In southern China and many regions in the world, rainfall is very abundant, the soil is soft and has high water content, and they cannot carry soil preparation machines and tractors at all. the weight of

In southern China and many areas in the world, it is usually a hilly area with dense terraces or a mountainous area with narrow roads, full of ravines and ridges. Soil preparation machines and tractors cannot walk in these areas at all, which greatly limits the use of land preparation machines. Therefore, until now, farmers in these areas still need to rely on hoes, oxen, plows and other agricultural tools to complete the process of land preparation manually, and the production efficiency is low. Therefore, the lag in the development of land preparation machinery has greatly restricted the agricultural development in China and many regions in the world.

[0004] The price of the tractor itself is high, and it usually needs to be used with more farm tools to reduce production costs. However, ordinary farmers have limited land area and fewer crops, so the cost of using tractors is high; More, complex structure, higher price, which also limits the scope of use of the soil preparation machine
