Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an agricultural machine capable of carrying out various operations such as tilling, crushing soil, fertilizing, sowing, compacting, and spraying chemicals all at once in one stroke of the tractor.

In general, agricultural technology involves improving fertilizers, pesticides, etc., and harvesting machines.

While there has been significant progress in mechanization such as pest control machines, little progress has been made in agricultural machinery used to perform basic agricultural tasks due to changes and complexity of soil.

That is, tillage work is currently carried out mechanically using a rotary tiller, but with this rotary tiller it is difficult to till deeply, and the high-speed rotation G of the soil crushing claws causes the dust to be crushed. It has the disadvantage that it precipitates on the tiller, making the tiller shallower and lowering soil productivity.

Therefore, there is a phenomenon in which turning the tilled soil over by deep tilling is insufficient and υ [there is a demand for a review of this rotary tilling method in which the soil is made shallower, and a return to the 1F tilling method of the previous era in which plows or falcons were used to till the soil. The reality is what is happening.

On the other hand, increasing the efficiency of agricultural work has a significant impact on the cost of agricultural products, so there is a trend to use tractors with high horsepower to save labor and to eliminate the loss of crops due to delays in the sowing season. However, when such heavy large tractors are used, the soil, which should normally be swollen and soft, is compressed by the thick tires and becomes hard. This causes problems such as the fertile soil in the surface layer of the soil being washed away, resulting in a decrease in soil fertility.

Classification of various types of work such as chemical spraying When a large tractor is used to shovel into cultivated land, each time the soil is trampled more and more, problems such as those mentioned above will be exacerbated. There is a problem in that it is inefficient to do it separately.The present invention is an attempt to improve this in view of the above-mentioned conventional situation, and the purpose of the present invention is to In addition to deep plowing, crushing, fertilizing, sowing, and compacting.

In some cases, each chemical spraying operation is performed as an integrated operation in one stroke of the tractor.

In other words, in case of misfire #i, by installing a disk at the front of the tractor so that it can be forcibly driven, deep plowing can be achieved and the traction resistance can be reduced by forcibly driving the disk.
In addition to tilling with discs, soil crushing, fertilization, seeding, compaction, and chemical spraying can all be carried out as an integrated operation by a relatively small tractor, which improves work efficiency, reduces labor, and reduces fuel consumption. This is a feature of the present invention, and the gist of the present invention is to attach an appropriate gearing to the front of the tractor body. The tractor is equipped with a plurality of discs mounted on the shafts at intervals of one foot at a corner, which can be forcibly driven, and a crushing claw is installed at the rear of the tractor body so that it can be forcibly driven, and behind the crushing claw there is a pressure roller. is rotatably installed between the compaction roller and the crushed soil nails,
