Farming machine and farming method thereof

Abstract

The invention relates to the field of farming machines and tools, and aims at providing a farming machine and a farming method thereof. The farming machine comprises a machine frame, two coulter wheels, two drag wheels and a dragging and farming device. The coulter wheels and the drag wheels are symmetrically arranged on the two sides of the machine frame, and the coulter wheels are arranged in front of the drag wheels. The farming machine and the farming method thereof have the advantages that multiple coulters are arranged on the coulter wheels of the farming machine, when the farming machine is driven to moving forward, framing can be conducted simultaneously, the dragging and farming device is arranged at the bottom of the farming machine, the driving force which is generated when the coulter wheels conduct farming is utilized to the maximum extent to supplement farming in the empty portion in the middle, maximization of power farming efficiency is achieved, braking devices which are arranged on the drag wheels are used for controlling the forward velocity of the machines and tools and balancing the forward force and braking force of the farming machine, and the purpose of deep farming through the coulter wheels under half skidding condition is achieved.

Description

technical field [0001] The invention relates to the field of farming machines, in particular to a farming machine and a farming method thereof. Background technique [0002] In agricultural production, dryland crops must be plowed in winter before sowing or transplanting. In order to be more conducive to crop growth, the general agronomic requirement is that the plowing depth should reach 200mm, which is conducive to the growth of crop roots and soil moisture conservation. To ensure the yield and quality of crops, this is the so-called deep plowing operation in agricultural production. Especially in late autumn and winter, plowing the deep soil to the surface can effectively reduce pests and diseases and increase soil fertility. [0003] At present, my country's agricultural machinery only has plows and disc plows that are towed by high-horsepower four-wheel tractors to operate in plain areas. Part of the farmland in mountainous and hilly areas plowed by small-scale agricult...

Problems solved by technology

[0004] The existing rotary tiller mounted on the walk-behind tractor generally has a radius of rotation of 210mm, deducting the radius of the transmission box of 90mm, and theoretically the maximum plowing depth can reach 120mm. Fracture, in general, the actual plowing depth is 100mm

That is to say, for the arable land in the vast mountainous and hilly areas, if the plowing radius of the coulter is simply increased or the plow plow and disc plow are used to achieve the purpose of deep plowing, the failure rate of the equipment will increase with the increase of plowing depth. Significantly improved, and the device that produces resistance in the existing micro-tillage machine is generally a resistance bar, which generates a certain resistance by inserting the resistance bar into the ground, and slows down the speed of the micro-tillage machine, thereby increasing the depth of cultivation. However, the resistance bar is actually There are many inconveniences in use. The resistance generated by the resistance rod is affected by the soil properties, and the resistance is difficult to control, resulting in unstable plowing depth, and it is easy to wrap the vegetation branches during the travel of the resistance rod, which affects the use.

[0005] The company has previously developed a farming machine for the above problems, which is driven by the coulter wheel, and uses a resistance wheel with a support block and a brake device to generate resistance, which can effectively increase the tillage depth. The ground where the coulter wheels pass by on both sides is plowed, and there is missing tillage in the middle. For the ground that has been missed for the first time in the middle, a coulter wheel in another stroke needs to be accurately aligned with the part of the missing tillage, which is labor-intensive and time-consuming. At the same time, there is also a certain degree of difficulty in operation, and the drag resistance of the previous agricultural machines was lost in the friction of the brake device, and was not used, resulting in waste
