Cultivators - Agricultural mechanisms from the list of the main techniques used in agriculture.Today there are many varieties of this unit, both domestic and imported.Cultivator continuous processing, as opposed to the plow, loose soil without overturning.Its main function, regardless of species - the cultivation soil.
Classification
Cultivators Soil preparation is classified according to various criteria.First, depending on how they are connected with a tractor, they are divided and mounted on a trailer.
Cultivators separated and the destination.The first group includes Cultivator for continuous tillage (preplant or steam).It is used for loosening while controlling weeds in the care of vapors or soil preparation for sowing.
next group - Tilled cultivators.With their help, processed row crops, destroy weeds cropping and seeding the ground, and in addition, spend fertilizing crops and hoeing between rows.
separate group - special cultivation: forest, garden and erosion control.During operation, they consume almost 100% of the weeds.When loosening the soil to prevent removal of the machines wet layers on the surface.
Mention should also be universal cultivators, performing two or more processing operations on the ground.
Depending on the number of processed rows cultivator for continuous tillage refers to either a single-row or multi-row to.In addition, the units differ in the working bodies and accordingly are called: plowshare (Tine), milling, rotary, disk.
device cultivators
general structural diagram of cultivators consists of the following assemblies: frame, working bodies (wheels, milling knives, legs and so on. D.) And a system of attachment (plate holders paws, ridges, and so. Etc..), or driving the supporting wheels according to the form (Attachment disc harrow for continuous tillage has no supporting wheels).
circuit also includes devices and mechanisms: translation machine from the transport position to the working and vice versa, to adjust the working depth of installation and by a predetermined row spacing and also the steering gear.
Application
cultivators Cultivator for continuous tillage is used, as a rule, prior to planting crops for cultivation of soil and simultaneous alignment of the microrelief, to control weeds after the crop harvested early.The unit carries out loosening the soil and mulching, as well as its adjustable seal.
workflow is as follows: during the power stroke on the field lancet paws cultivator loosen the surface layer to a predetermined depth, cut the weeds, and a special device, located at the back aligns furrow.
cultivators cultivate the land cultivated for crops, spring crops, vegetable crops, as well as make the process vapor to conserve soil moisture.Aligning surface field cultivator reduces the number of passes of other agricultural machines and provides high performance of subsequent operations.
