Description

 .one

. The invention relates to agricultural machinery, in particular, to methods and devices for sowing loose materials that can be used in crops for applying mineral fertilizers, pre-chemicals, seeds 1 (grains and other crops.

There are known methods for sowing loose materials and devices for their implementation, which include transportation to the high hole and sowing of loose materials from it by rotating the W & auger 1.

The disadvantage of these methods of elevation, in bulk materials and devices for THEIR, is the unevenness of seeding along the length of the screw.

The closest to the invention to the technical essence and the achieved result is a method of sowing bulk materials, which includes transporting hollow shthangs to seed holes and sowing bulk materials from them by vibrating the last hollow pole 2.

This method is widely used dh combining transportation and do-. bulk material, however, the placement of the operation of the vibratory transport porting with simultaneous dosing with alternating load with one frequency component presents great difficulties, since to ensure a large throughput of the distributor of the dispenser it is necessary to create high-intensity vibratory influences that lead to significant perturbations in the design itself, and therefore, affects the reliability of the working process of this method. The working process of this method at low frequencies and large amplitudes implies a pulsation of the seeded material flow.

The closest technical sushi to the present invention is a device for sowing bulk materials, containing: a frame with running wheels on which the frame is mounted horizontal, spaced across the movement, the floor of the head with seeded holes, which kinesm is tied to vibrating mechanism yes 21 ..

The disadvantage of this device for sowing loose material is the insufficient uniformity of sowing along the length of the hollow rod, due to the possibility of ablation at some moments, it sows the sowing holes of the rod with a different material.

 JoSoRent - shlyi e rvvnb dimensionality of seeding bulk material.

This goal is achieved by the fact that according to the method of seeding bulk materials, including transportation to seeding

the hollow rod holes and seeding loose materials from them by vibrating the last hollow rod, the bulk material in the area of the seeding holes of the hollow rod is subjected to additional vibration by means of pivotally mounted oscillating rods, and the frequency of vibration of the rods is greater than the frequency of vibration of the hollow rod by 2-3 times.

Q In a device for sowing loose materials, which contains a frame with running wheels, on which is mounted horizontal, placed across the movement, the floor bar with sowing holes, which is kinematically connected with the mechanism 5 of the vibrodrive, plates with rigidly mounted on them are mounted on the shaft 5 and rods placed in the zone of sowing holes, the plates being equipped with an autonomous vibration drive mechanism. The autonomous mechanism of the vibrodrive is made in the form of a roller and a conical eccentric which are conjugated to each other, which is kinematically connected with one of the drive wheels.

FIG. 1 depicts the proposed 5; a device for carrying out method i for seeding bulk materials; in fig. 2 is the same, section A - A in FIG. I,

The loose material seeding device contains the installed bunker frame, ker (not shown), which is common with set0; a horizontal hollow flange mounted across it, placed across it: 1, which is suspended on flexible elements 2 and is kinematically connected with the vibrodrive mechanism, made in the form of a hydraulic cylinder 3, working cavities 5, which are connected to the valve 4 of the spool type, kinematically connected driving wheel 5 seconds In the lower part of the hollow UiTaHrH hollow, sowing holes 6, in which rods 7 are installed, rigidly fixed 1 plates 8 that are pivotally mounted on shtaig 1. Plates 8 through a spring-loaded spring 9 t gu 10, double-arm lever P with a spherical roller 12 are connected with a conical excitrik 13, 5 the latter with a centrifugal regulator 14, the I drive of which is made from the running wheel through the gear 15, and with the “running wheel using the gear 16. During the forward propagation of the seed spill, material from the I bunker (not shown) through the loading 0 : pipe The rows enters a hollow schtachgu 1 .kotora receives reciprocating translational oscillating movement QT gidrotsiliidra 3. Simultaneously, via the thrust 10 dvuple: Chii lever And, the spherical roller 12 and to: nical eccentric oscillating motion 13 |. plate 8 with rods 7 receives;

The curved ends of the hollow rod 1 eliminate material compaction in

degraded boom zones due to the fact that they form a "fluidized bed of sown material, the particles of which move upwards to a certain position (depending on the mode of vibration) and under

The action of gravity rolls down. Thus, continuous n-rhodol circulation of material is created in the rod, which eliminates its compaction. With

The rods 7 are affected by the circulating material. The oscillation frequency is: different from the oscillation frequency by the vibrating rod 1. In the zone of the seed hole b, the transported material is subjected to a pulsating dynamic effect whose pulsation frequency is determined by the oscillation frequency of the rod 7. The seeding zone is characterized by : a state of bulk material, which: acquires the property of flowability and is uniformly sown through bore 6.; V Gear ratio of gearboxes 15 and W.us | ana vyva atta m, so that the frequency of action of the rods on the leveled material l je 2-3 times exceeds the frequency of vibration of the rod i, and the oscillation frequency of stfny I is a function of the number of revolutions of the traveling wheel 5. The magnitude ofKJfjbfti plate 8 is determined by a conical eccentric 13: increasing wheel speed 5 centrifugal peryJiiiTop 14 moves the cam in. the side that determines the large value of the opening of the plate 8. When reducing the revolutions of the traveling wheel or stopping the crop, the eccentric is reversed in the opposite direction or returns to the neutral position

at the stop of the spray. The compression spring 9 returns the plates 8 in the direction of closing the sowing holes 6.

Sowing dosing) bulk material with vibration || 1 mode of rods 7; provides more effective dosing, since all the sowing holes 6 are in equal conditions, as a result. This ensures that the Square Duty is maintained in the area of the sowing holes.

Advantages of the proposed device for loading bulk materials

Its versatility is conclusive. sch. with the ability to sow various SEE materials, ease the change of the norm. Seeding without replacement. Working parts.
