RU164316U1 - TILLING MILL WITH F-SHAPED KNIVES - Google Patents

Abstract

A tillage mill for cultivating the soil, including a skeleton, a casing, a housing, a shaft bearing, knives, characterized in that on the hexagonal shaft evenly F-shaped knives are arranged alternately on the inner and outer sides from the inner and outer sides and secured with retaining screws on both ends of the shaft rings.

Description

The utility model relates to agricultural machinery, in particular to milling tillage machines.

Known rotary tillage machines with L-shaped knives [1].

The disadvantage of this cutter is only a partial achievement of the required quality of soil treatment, depending, for example, on soil moisture or mechanical composition.

Known tillage cutter containing a skeleton and a shaft with mounted disks with T-shaped knives [2].

The disadvantages of these milling cutters are insignificant pushing forces in the system of the machine-tractor unit, which leads to increased slipping of running systems and insufficient loosening of the soil in layers, leveling the surface of the field and the destruction of weeds.

The purpose of the utility model is to improve soil cultivation, increase its physical structure and pushing forces in the system of a machine-tractor unit.

This goal is achieved by the fact that on the hexagonal shaft evenly, due to the hexagonal bushings, knives of the F-shaped form and retaining rings fixed at both ends of the shaft are alternately located on the inside and outside. Knives interacting with the soil alternately loosen it to the desired physical structure, depending on the shaft rotation frequency. Due to the F-shaped form of the knives, the best soil cultivation effect is achieved. Having this design of knives, the push action of forces on the tractor increases, which increases the traction and coupling properties of the unit as a whole.

In FIG. 1 shows a tillage cutter - main view, in FIG. 2 is a side view.

The cutter consists of a core 1, a casing 2, a bearing housing 3, a hexagonal shaft 4, at the beginning and at the end of which circlips 5 are mounted, and between them there are evenly arranged hexagonal sleeves 6, on the inside and outside of which are bolted 7, knives 8 F-shaped.

The principle of operation of the cutter is as follows. A circlip 5 is mounted on the end of the hexagonal shaft 4. On the hexagonal sleeve 6, on the inside, bolts 7 are fixed, knives 8 are F-shaped, and on the outside they are fixed knives without sleeve 6. Having collected the required number of knives, depending on the width of the treatment soil, fix the retaining ring 5.

When rotating from a drive (not shown), the hexagonal shaft 4 transmits torque due to the hexagonal sleeve 6 and bolts 7, to the F-shaped knives 8. Knives 8, alternately interacting with the soil, loosen it, depending on the frequency of rotation of the shaft, to the desired structure. Due to the F-shaped knives, the best soil cultivation effect and simplicity of construction are achieved.

The use of this device makes it possible to improve the quality of soil cultivation and the reliability of the tillage machine, including reducing the energy consumption of the cutter due to the alternate interaction with the soil.
