Description

Sowing machines for seeds of various agricultural crops with a finger agitator; 1 reader: -r and a seed box. I have; :; with curved feed icaiia.i, HSBCCTHSjt.

The disadvantages of such seeding anlaratov 51c :; Low operational reliability associated with the operation of an endless belt, enveloping a few rollers / inconvenience of adjusting the height t, the rape-like stopper and insufficient uniformity of the sowing seed, occurring due to the absence of vibrations in the area of laying the seeds, angular called belt machine.

In the apparatus described, these shortcomings are eliminated by the fact that the main;) working apparatus of the apnarata is made in the form of an elastic short material roller with an angular groove on the circumference, and a stop in the form of a rotating sprocket with several trapezoidal teeth of different length, set over roller groove.

In addition, the swivel limiter is attached to the binder with a fingertip to the shaft, which is driven in reciprocating rotation with the spring-loaded lever and the cam disc attached to the same shaft with the seeding roller.

Ka fkg. depicts a partial longitudinal section of the sowing apparatus of the apparatus-side view; in fig. 2- partial cross-section view from the middle; in fig. 3-side view of the apparatus from the side of the drive of the finger agitator.

In the corzus} of the sowing apparatus there is a curved seed-feeding channel 2, and on the shaft 3 there is a seeding roller 4, made of elastic material and having an angular groove 5 along its entire circumference.

On the shaft 6 are mounted, inside the “Ornus / apparatus,” finger pocket 7, and above the sowing roller there is a 4-limiter 8, which can be used in the form of an asterisk, imeyunkhe1 (HiecTb of transverse-shaped teeth of various lengths. In addition, a spring-loaded lever 9 is mounted on the shaft 6 outside the apparatus, resting on the protrusions of the cam disc 10, which is fixed outside the apparatus on the shaft 3.

Pr, and the work of the spruce equipped with the described sowing devices from the traveling wheel through the appropriate gear} is driven into the rotation of the shaft 5 with the sowing roller 4. Semen coming in by the hot box along the curve of that frame 2 are filled with an angular groove 5 and carried away by roller 4, rotating in the direction of arrow A. 1; the quality of the seeds captured by the rollers 4 is determined by the degree of immersion in the angular groove of the tooth;

The cam diode 10 rotating together with the shaft 3 oscillates lever 9, which in turn continuously P0: thief, and shaft 6 in the opposite-willed direction 6, thereby creating the vibration of the limiter 8 above the seeding groove and the finger rotator 7 inside the body of the device.

To change the amount of seeding, the locking screw / L is loosened and limiter 8 rotates on the shaft b so that the tooth of the corresponding length is set to position B (Fig. 1), after which the limiter stops BlHHTOM //.

Claims (2)

1. Sowing machine: AT for seedlings of various agricultural crops with finger thrusters, limiter and seed box, which has a curved feed channel, so that, in order to change the cross section of the flow of sown seeds, i.e. for sowing them with single grains, or with a general continuous flow, as well as to increase the convenience of adjusting the seeding, the main working body of the device is made in the form of a rotating roller of elastic material with an angular groove around the circumference, and the limiter is in a rotating sprocket with several Along the trapezoidal teeth of various lengths mounted above the groove of the roller. 2. The form of execution is sown 1, its apparatus according to claim 1, in order to improve the reliability of sowing seeds, the rotary stop is attached to a shaft with a finger agitator and is brought into returning the rotator} the aid of a spring-loaded lever and a cam dioka fixed on the same shaft with a seeding roller.
