Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to cultivators, seedlings and cultivators. The purpose of the invention is to increase the uniformity of the seed embedment depth and improve their contact with the soil. The opener consists of a frame 1 with a deepening mechanism 2, a gr dil 3, racks with this wire 4, paws 5, a copier 6 in the form of a two-arm lever, coupling 7, a slider 8, and hinges 9. Before digging down the copier 6 under the action of its mass or spring is positioned vertically and the arm connected by a hinge 9 with th 7, raises the pull and the slider 8 to the upper position. In the case of burial, the coulter is buried until the copier 6 contacts the soil surface. When the copier 6 interacts with the soil, it rotates around the hinge 9 fixed on a stand 4 and its shoulder through the tie 7 connected by the hinge 9 from the bottom with the slide 8 pushes it down (to the bottom of the furrow). In steady motion, an equilibrium of torque is achieved. The ratio of forces acting on the copier 6 and the slider 8 is adjusted by the length of the copier 6 arms.

(57) The invention relates to agricultural machinery, in particular to cultivators, seedlings and cultivators. The purpose of the invention is to increase the uniformity of the seed embedment depth and improve their contact with the soil. The opener consists of a frame 1 with a deepening mechanism 2, a gr dil 3, racks with this wire 4, paws 5, a copier 6 in the form of a two-arm lever, coupling 7, a ram 8, hinges 9. Before penetration, the copier 6, under the action of its mass or The springs are positioned vertically and the arm connected by the hinge 9 with the thrust 7, lifts the pull and the slider 8 to the upper position. When buried, the coulter is buried until the copier 6 touches the soil surface. When the copier 6 interacts with the soil, it rotates around the hinge 9 fixed on a stand 4 and its shoulder through the tie 7 connected by the hinge 9 from the bottom with the slide 8 pushes it down (to the bottom of the furrow).

FIELD OF THE INVENTION The invention relates to agricultural machinery engineering, in particular to cultivators, seedlings and cultivators.

The purpose of the invention is to increase the uniformity of the seed embedment depth and improve their contact with the soil.

The drawing shows the scheme of the coulter with depth gauge.

The opener contains a frame 1, a mechanism 2 for burial, a groove 3, a rack 4 with this wire rigidly attached to the head 3, which is pivotally connected to the frame 1, a paw 5, a copier 6 in the form of a double-shouldered lever, a tu 7, a slide 8 , hinges 9. The copier is mounted on a common hinge 9 on a rack 4, and is also connected by one shoulder with the help of another hinge 9 with a thrust 7. which in turn is connected at the bottom by a hinge 9 with a slider 8,

attached to the stand-sem wire 4 in the lower part of the hinge 9.

The opener with depth gauge works as follows.

In the raised position (before the deepening), the copier 6 under the action of its own weight or spring is positioned vertically and with its shoulder lifts the pull 7 and the slider 8 to the upper position. When lowering to the depth, the coulter sinks into the soil until the copier 6 contacts the soil surface. When interacting with the soil, the copier 6 rotates around the hinge 9 mounted on a stand 4 and with one arm acts on the pull 7, which advances the slider 8 until it interacts with the bottom of the furrow. Supporting the bottom of the furrow, the slider 8 creates a vertical force pushing the coulter from the soil. The ratio of forces, deisto

They are controlled by the copier 6 and the slider 8, and the depth of the stroke is adjusted by the length of the copier 6 arms. In the steady-state motion, an equilibrium of the torques is achieved. In this case, the force acting on the copier 6, Can be up to 1/10 of the force acting on the slider 8. The main load on the retention of a given depth of stroke is perceived by the slider 8 and the bottom of the groove. This significantly prevents the compaction and shear of the topsoil.

Copier in the form of a two-armed lever less prone to sticking soil. Sealing the bottom of the furrow of the slider 8 is useful when using the opener for sowing crops. The seeds pass through stand 4 and fall to the bottom of the furrow. Then they are pressed into the soil by the slider 8, improving contact with it. The share is triggered with

lag, so the change in depth responds smoothly. It is advisable that copier 6 is slightly in front of the rack,

Claims (1)

Claim of an Insertion Vomer containing a paw, a rack with this wire, a deepening mechanism and a copier-limiter, characterized in that, in order to increase the uniformity of the seed embedment and improve their contact with the soil, the latter is made in the form of a hinged pin at one end behind the stand to the lower part of the ram and hinged at the top of the rack of the copier in the form of a two-arm lever It is mounted with the slider by means of vertical tie rods and hinges.
