RU2442307C1 - Double-disk furrow opener - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention may be used in seeding-machines when the seeds are put into the furrow. The furrow opener includes the body, the disks fixed on it, and the seed depth adjuster. The seed depth adjuster is equipped with the skid and the coverer in the form of a bent plate and is made in the form of a plug with the regulating tine located inside it. The vertical movement of the tine is performed with the help of a limiting bolt locating it in one of the open-ended threaded holes of the plug. The curved lower end of the tine is firmly fixed on the skid with the beam. The plug is firmly fixed on the furrow opener body with the plate at the junction of the draw-bar and the body.

EFFECT: increase in the uniformity of the seed depth in combination with the simple design and adjustment.

Description

The invention relates to agricultural machinery, in particular to devices for setting the depth of seed placement.

A harrow is known whose teeth perform the function of a coulter. To adjust the seed placement depth, the harrow can be adjusted vertically. To do this, a rack with an adjusting bolt is installed in the front of the harrow frame, while the rack is rigidly fixed to the shoe (US patent No. 3670670 A) - [1].

A disadvantage of the known harrow is that during its operation a uniform seed placement in depth is not provided, because the shoes mounted in the front of the frame cannot provide quality control of the seed placement depth of each opener individually.

A double disc opener is also known, comprising a housing and discs. On the outside of the disks, ring plates are fixed with screws that connect the guides. A number of holes are made in the guides. On the rails mounted pochozatech. The position of the couplings on the rails is fixed with clamps and screws. The latch passes through the hole made in the couch and the guide (RF patent 740178, IPC A01C 7/20) - [2].

A disadvantage of the known coulter is that it can only work when sowing to a shallow depth, for example grasses, as well as the difficulty in setting up, constructive design and expensive to manufacture.

The objective of the invention is to increase the yield of grain crops due to the uniform depth of seeding, simplifying the design and configuration, as well as reducing the cost of manufacture.

The task is achieved due to the fact that in the well-known double-disc coulter containing a housing, disks mounted on it and a mechanism for regulating the depth of seed placement, according to the invention, the mechanism for regulating the depth of seed placement is equipped with a support ski with a shortener and made in the form of a sleeve with an adjustment finger located inside it, the vertical movement of which is carried out using a restrictive bolt, placing it in one of the through threaded holes of the sleeve, in addition, the curved lower end of the ulirovochnogo finger rigidly connected to the supporting beam by means of a ski, which carries the earthing devices in the form of a curved plate, while the sleeve itself is rigidly secured by plate on the coulter body at the junction with the leash housing.

The technical essence of the proposed double-disc opener is presented in the drawings, where Fig. 1 shows a diagram of the proposed control mechanism, front view; figure 2 is the same, a top view; figure 3 is a drawing of a double-disc opener with the proposed regulation mechanism.

The double-disc coulter contains a housing 8 with disks 11, on which a control mechanism is installed, consisting of a sleeve 1 with an adjustment finger 2 located inside it, the vertical movement of which is carried out using a restrictive bolt 3, placing it in one of the through threaded holes made in the sleeve 1 through equal distances.

The curved lower end of the adjusting finger 2 is rigidly connected by means of a bar 4 to the support ski 5, in turn to which the zagotchok 6 is attached in the form of a bent plate rigidly fixed to the support ski 5. The sleeve 1 is attached to the plate 7, which is mounted on the opener body 8 in the connection point of the leash 9 with the housing 8. In the housing 8 of the opener a receiving funnel 10 is installed, from which the seeds come to the disks 11.

Double disc coulter works as follows.

At the beginning of work, the control mechanism is set to a predetermined seed placement depth by setting the adjusting finger 2 relative to the sleeve 1. To do this, using the restrictive bolt 3, the finger 2 is fixed in one of the seven through threaded holes of the sleeve 1, thereby setting the required seed placement depth. When sowing discs 11, relying on a support ski 5, form a groove for seeds at a specified depth, from one to eight centimeters.

When the coulter passes through discs 11, a groove is formed, into which seeds come from the receiving funnel 10. Closing them with soil is carried out using zagortachka 6.

The proposed device for setting the depth of seeding allows you to:

- stabilize the depth of seeding;

- evenly cover the seeds with soil;

- simplify the design and configuration of the device.
