Cultivator for continuous tillage for agricultural crops

Cultivators - agricultural mechanisms from the list of the main equipment used in agriculture.

Today there are many varieties of this.unit of both domestic and imported. The cultivator of continuous processing, in contrast to the plow, loosens the soil without turning the reservoir. Its main function, regardless of the variety, is the cultivation of the soil.

Classification

Cultivators for tillage are classified according to various criteria. First of all, depending on how they are connected to the tractor, they are divided into trailed and mounted.

Культиваторы разделяются и по назначению.The first group includes a cultivator for continuous tillage (pre-sowing or steam). It is used for loosening with simultaneous destruction of weeds when caring for couples or preparing the soil for sowing.

The next group is tilled cultivators.With their help they cultivate tilled crops, destroy weeds by cutting and sprinkling with earth, and in addition, they feed crops and loosen up the spacing.

Separate group - special cultivators:forest, garden and anti-erosion. During operation, they destroy almost 100% of the weeds. When loosening the soil, such machines prevent the outflow of wet layers to the surface.

Mention should also be made of universal cultivators performing two or more tillage operations.

Depending on the number of rows processedcultivator for continuous tillage refers to either single or multi-row. In addition, the units differ in the form of working bodies and, accordingly, are called: plowshares, milling, rotary, disk.

Device cultivators

The general design scheme of cultivators consistsof the following assembly units: the frame, the working bodies (discs, milling knives, feet, etc.) and their fastening system (plates, paw holders, ridges, etc.), running or supporting wheels, depending on the type (disc mounted cultivator for continuous tillage has no support wheels).

The circuit also includes devices andmechanisms: to move the machine from the transport position to the working position and vice versa, to adjust the depth of immersion of the working bodies and to install at a predetermined aisle, as well as the steering device.

The use of cultivators

Cultivator for continuous tillagethey are used, as a rule, before planting crops for cultivating the soil and simultaneously leveling the microrelief, for weed control, after the early harvest has been harvested. The unit loosens and mulches the soil, as well as its adjustable compaction.

The technological process is as follows:during the working stroke across the field, the cultivator's lancet paws loosen the surface layer to a predetermined depth, cut off the weeds, and a special device located at the back aligns the furrows.

Cultivator cultivate the land for cropstilled, spring, vegetable crops, and also do the processing of vapors in order to preserve moisture in the soil. Leveling the field surface with a cultivator reduces the number of passes of other agricultural machines and ensures high performance of subsequent operations.
