Description

Multipurpose farm machine

The present invention relates to a multipurpose agricultural machine.

Various agricultural machines such as tillers, rice transplanters or binders or combines have improved labor productivity in lieu of the laborious and laborious work previously done by manpower.

Among the various agricultural machines, tillage machines are more versatile than other machines and have relatively low prices, so each farm has about one unit. The cultivator can be used for transporting goods by attaching a trailer to the back, or for tillage or stopping of cultivated land, or can also be used to pump pesticides.

On the other hand, there are many processes that are essential for field farming. For example, the process of grinding hardened soil to crush soil masses, the process of making a mockup in the field before sowing, fertilizing the fertilizing process, installing vinyl coverings, and spraying pesticides according to the growth of crops. Etc are those things.

By the way, most of the above works other than the work to make soil or mockup are done by the workforce, so physically very difficult and low productivity. For example, the fertilization process involves a person walking along the furrow and dispersing fertilizers by hand.Spreading fertilizers on the field to a uniform degree requires more experience, and in the case of large fields, fertilizers are transported far away. There was a inconvenience to go.

Also, to cover the field with vinyl, one person grabs the end of the vinyl and the other walks to the other side while unwinding the vinyl and places it face to face on the toe, while the other is furrowed on both edges of the plastic sheet. This involves a very cumbersome process, such as raising soil.

The process of spraying pesticides as the crops grow is also inconvenient. Spraying pesticides from a distance using high-performance pumps and nozzles does not reach the rear or bottom of the crop properly. In order to properly deliver pesticides, a person must walk along the furrow and apply pesticides to the back and bottom of the crop. Despite knowing the above facts, walking around the furrow can not give pesticides because it is so much power and time-consuming.

The present invention was created to solve the various inconveniences described above, and can be used as a cultivator, a chemical sprayer, a vinyl installation machine, a stationary machine, a fertilizer feeder, or a mock molding machine, and the like, so that almost all kinds of farming operations are possible.
