SU913959A1 - Cultivator for tillage of cotton fields - Google Patents

Description

The invention relates to agricultural machinery, and more particularly, to machines for inter-row cultivation of crops, for example cotton, by loosening the soil and controlling weeds.

Known trailed and mounted cultivators with working bodies (legs), mounted on rigid racks [1] ·

The disadvantage of these cultivators is that the quality of cultivation depends entirely on the condition of the soil.

The technical solution closest to the invention is a cultivator for processing cotton fields, including a frame and passive and active working bodies attached to it with a drive mechanism [2].

A disadvantage of the known cultivator is low quality, due to the impossibility of processing / field in the transverse and longitudinal directions.

The purpose of the invention is to improve the quality of processing.

The goal is achieved by the fact that the cultivator ⁵ is equipped with an additional active working body, which has combs fixed on the rotary arms in transverse vertical arms.

In this case, the rotation arm of the rocker arm is made in the form of a gear and gears that are engaged with it, eccentrically fixed with connecting rods with free arms of the rocker arm. In addition, the gear has a ring gear for 2/3 of its circumference.

In FIG. 1 shows a cultivator, _{Λ is} a side view, * in FIG. 2 - active working body, rear view; in FIG. 3 trajectory of the active working body when processing two rows of cotton fields.

The cultivator has a running wheel 1 and a frame 2. Passive working bodies 3, active working bodies 4 working in the longitudinal direction and an additional working body 5 working in the transverse direction are fixed to the frame. At the rear of the frame is a perch 6. The active working element 4 is a metal round comb 7 mounted on a rotating vertical shaft 8. The shaft 8 is located in the bearing 9. There is a bevel gear at the upper end of the shaft 8

10, which is driven by a bevel gear 11 rigidly mounted on the shaft 12. The shaft 12 is driven by a tractor power take-off shaft.

The additional working body 5 also represents metal combs 13 mounted on the beam 14, which are pivotally mounted on the frame 2. To the upper ends of the beam 14, the connecting rods 15 are pivotally connected, which in turn are pivotally connected to the gears 16.

One of the gears 16 is meshed with the gear 17, which sits rigidly on the shaft 18 and is driven into rotation from the tractor PTO

Gear 17 has teeth (ring gear) for only 2/3 of the circumference. The ratio of the diameters of the gears 16 to the drive 17 is 1: 3.

Two cultivators can be attached to the tractor in parallel and four rows can be processed at once.

The cultivator works as follows.

When the tractor with the cultivator moves along the field to be treated, passive and all active working bodies work simultaneously.

The active working body 4, working in the longitudinal direction (along the tractor), constantly rotates and, following the passive working body 3, contributes to better cultivation of the soil and damage to weeds.

At the same time, an additional active working body 5, working in the transverse direction, loosens the soil and damages the weeds between the bushes in the transverse direction.

Since the pinion gear 16 has teeth only on 2/3 of the circumference, the gears 15 set the working bodies in motion periodically, that is, they work only while they are between the bushes, without damaging them. Zigzag strips are provided from the moment the teeth of the gear 17 are engaged with gears 16, due to the swinging movements of the rocker arm 14. The rocker arm 14 is swinged due to the fact that when the gears 16 rotate, the connecting rods 15, movably connected to gears 16, make reciprocating movements and inform the rocker arms 14 swinging movements.

Bypassing the bushes is provided while the gear 17 is

M is not meshed with gears 16, i.e. at this time passes the portion of the circumference of the gear 17, on which there are no teeth (1/3 of the circumference).

$ 2 and metal combs 13 are in extreme positions near the running gear 1, i.e. in the furrow. The hiller simultaneously forms a furrow for irrigation.

Using the proposed cultivator, simultaneously processing the field in the longitudinal and transverse directions, will increase labor productivity by 2 times,

2 ₅ reduce tractor shock absorption and save fuel and lubricants.

The proposed cultivator can also be used for thinning young seedlings of cotton (by destroying them), a work that is currently being done manually.

Claims (3)

The claims 45 1. The cultivator for processing, mainly cotton fields, including a frame and passive and active working bodies attached to it with a drive mechanism, of which ⁵⁰ , in order to improve the quality of processing, the cultivator is equipped with an additional active working body, which has mounted on rotary in ⁵⁵ transverse vertical planes rocker arms comb. 2. The cultivator in π. 1, characterized in that the rotation arm of the rocker arm is made in the form of a gear and gears being engaged with it, eccentrically fixed by connecting rods with free shoulders of the rocker arm. 3. The cultivator according to claim 2, characterized in that the gear has a gear ring on 2/3 of its circumference.
