Abstract

A double disc share (2), a sewing disc and the shanks (18, 19) of a slip shoe (6) are arranged on a common vertical transverse mid-plane (7) at their geometric centre. The sewing disc (5) is arranged in the space between the discs (3, 4) of the double disc share (2), a shank of a slotted slip shoe (6) extending on both sides of the discs (3, 4). The disc has a central bore (11), through which the sewing disc (5) bearing (12) passes. The disc (3) is pref. supported on a bearing tube (12).

Description

BACKGROUND OF THE INVENTION The invention relates to a seed drill for spreading various seeds in agriculture.

Seeders are known which make a furrow and are provided with a seed member that places the seeds in the open furrow, and then the seed roller presses the seed out into the soil and an element covers the furrow. Examples of such drills are described in 1,582.04? s. German Public Prosecution Document and U.S. Patent No. 1,943.670. German usage pattern.

No. 1,943,670. According to the German usage pattern, wedge shaped wax knives, to which a rotating disc may be attached, are used to make the groove. A seed disc is placed after the furrow plow, which places the seeds in an open furrow after the furrow plow.

Is 1,582.04? s. According to German Patent Publication 2, a double-disc plow is used as a furrow plow. This double-disc plow consists of two V-discs which are embedded in each other and form the furrow. Between these discs is a seed passage which places the seeds directly between the discs on the ground.

The disadvantage of these seed drills is that either the seeding is done too far behind the furrow tool and thus the fall back soil prevents seed placement or the machine is very long. In the event of a deposit between plow discs, the seed tube is not positioned at the desired distance, as the rolling seed disc can provide.

Λ It is an object of the invention to provide a seed drill capable of placing the seed to be sown at a desired depth at exactly the desired distance.

It is an object of the present invention to combine the furrow knife, the sowing element and the depth retaining element in the seed drill to achieve the object of the invention.

According to the present invention, the object is achieved by having the horns of a tuft plow, a seed disc and a crying pike slipper being disposed approximately centrally with their geometric center. In the space between the double discs, the seed discs are arranged in a space smaller in diameter relative to the diameter of the plow discs. The axis of rotation of the seed discs is arranged so that it is below the axis of rotation of the plows forming the plow or at a height at most. One of the discs of the double-disc harrow has a large bore in the middle through which the bearing tube connected to the frame extends.

This tube is provided with a hollow shaft which drives both the seed disc and, on the other hand, provides air passage and, in addition, bears one of the discs of the double disc plow. The seed disc is outwardly decreasing in diameter in both directions and fits far more in the angle between the plow discs. The discs are provided on both sides with slits of slit shoe, which performs the necessary depth adjustment. The invention is united by: provides the benefits of a double-disc plow with precise sowing via the seed disc and depth control. The required elements in the operating zone are arranged together and offset, as in previous solutions. The compact design significantly reduces the overall length of the drill. Gép The machine according to the invention always puts the seeds at the same depth and at a precise distance, regardless of the soil surface and the movable movement of the drill.

The invention will now be described in more detail with reference to the drawings, in which:

Figure 1 is a side view of an exemplary embodiment of a drill according to the invention.

Figure 2 is a schematic top view of Figure 1.

Figure 5 illustrates the placement of the disc plow and the seed disc.

In a fork-shaped frame 1, two double-disc plows of 5 and 4 discs with a V-shape, 5 seed discs and a HaI almi tiAninnr'a IR with IQ agar. OFL

grips the stud wheel around the 6 baby slippers.

The frame 1 further comprises a seed box 8, a pressure roller 9 and a guide 10.

The disc 5 of the double disc harrow 2 has a hole 11 in the center through which the bearing tube 12 of the seed disc 5 is guided. The hopper 12 has a hollow shaft 15 to which the vacuum line 14 of the drill is connected. In the exemplary embodiment, frame 1 is utilized for Airflow and. The diameter of the seed disc 5 is smaller than the diameter of the double-disc plow 2 and is located in the angular space between the discs 5, 4, while its axis of rotation 15 is below or equal to the axis of rotation of the disc 5.

It is arranged at an altitude of -2180236. Its outward cross-section is reduced in both directions in order to be better positioned in the angular edge between the discs 3, 4. 1 1 on 12 bearings? there is a bearing for picking up the 3 discs.

Szár The discs 18, 19 are arranged on both sides of the discs 3, 4 on the slipper slippers 6. The slipper 6 is adjustably mounted on the frame 1 by means of rods 20.

The front of the frame 1 holds a drive shaft 21, which is designed as a hollow shaft for the purpose of providing air passage and transmits the rotary motion to the seeding disc 5 by means of a conical drive 22. With the help of the head piece 23, the frame is mounted on its torsion on a rack not shown. A single seeder may be provided with a plurality of seeding devices described above.
