Description

The invention relates to agricultural machinery, in particular, devices for introducing liquid preservatives into the extrusion: ai feed with simultaneous bale formation.

A device for introducing a liquid preservative into a ferry food is known, which includes a mixing chamber inside which are mounted sprayers for preservative Cl.

However, this device is applicable to crushed silage and can only be used in stationary conditions.

It is also known a device for injecting liquid chemical preservatives into a bale containing a needle, the cavity of which through the distributor valve with radial channels and the supercharger of its trunk is connected with a reservoir for the liquid preservative G2.

However, this device does not allow to obtain a uniform distribution of the liquid preservative throughout the entire volume of the compressed feed, since it works not in a single technological process when forming a bale, but in isolation, i.e. when the bale or roll is already formed, and this leads not only to the uneven distribution of the preservative in the compressed bale, but also to its increased consumption.

The aim of the invention is to obtain a more uniform distribution of the liquid preservative throughout the entire volume of the compacted mass in the process of forming the bale by the baler.

The goal is achieved by the fact that the distributor distributor is fastened to the front side of the baler piston and in it connects to the discharge line and the radial and channels axial channel in which a spring-loaded check valve is installed, the stem of which is connected to the plunger and has a stop for the stop into the compressed bale mass, with the spool-distributor installed in the needle cavity, which is mounted on it pivotally with the possibility of rotation, and protrusions with through channels are made on its surface, which The latter are turned to the front side of the piston and communicate with the channels of the spool-distributor.

FIG. 1, a schematic representation of a device for introducing liquid preservatives into bales, side view; FIG. 2 is a section A-A in FIG. one; in fig. 3 - valve-distributor cut.

A device for injecting liquid preservatives into bales includes a hollow

a grooved needle 1, on the surface of which there are protrusions 2 with through channels 3 facing the front side of the piston 4 of the baler. The corrugated floor needle 1 is installed by means of angular contact bearings 5 on the distributor zolotniki 6, which is attached to the front side of the piston 4 of the baler. Inside the spool valve b is installed with the ability to regulate the pressure of the injection of liquid preservative in the pressii ngk shut off valve 7, which is exerted on the side of the discharge line spring 8, freely placed in the groove of the threaded fitting 9, which is connected to the reservoir 10 with the flexible hose for preservatives (not shown). A piston 11 is installed in front of the spool valve b with a sealing lip 12. A rod 13 is placed in the internal cavity of the pusher 11, which interacts with the shut-off valve 7. To unload the shut-off valve 7 and return the pusher 11 to its original position in the spool-distributor 6 the spring 14, which at one end acts on the pusher 11 and yes) rests against the groove in the distributor spool. To eliminate the leakage of the liquid preservative through the sealing collar 12, the latter is clamped by a nut 15 with an axial bore through which the pusher 11 passes. In the middle part of the distributor spool 6, for the outlet of the liquid preservative into the internal cavity of the corrugated needle i, 16 are drilled the central axial channel 17c is connected with a grooved needle cavity. In the front of the grooved needle, in the direction of the piston being pressed, a conical cap 18 with an axial bore is fastened through which the shank 19 of the pusher passes. Liquid preservatives are fed to the axial channel 17 from the tank for the liquid preservative and the pressure line (not shown, / "

A device for injecting liquid preservatives into compressible bales works in the following way.

At steady state operation of the baler, the piston 4 captures portions of the pressed material and compresses them in the bale chamber. Simultaneously with the movement of the piston, the needle 1 is inserted into the pressing of the floor of the corrugated into the previously compressed mass and the shank 19 of the pusher 11 abuts against it, resulting in

the pusher moves and, acting through the rod 13, removes the shut-off valve 7 from the socket, overcoming the resistance of the spring 8. As the result of the shut-off valve coming out of its socket, the liquid preservative, under pressure developed by the pump, enters the central axial channel 17, and from it through the radial No the channels 16 passes into the internal cavity of the corrugated needle 1, followed by its introduction into the formed bale through the channels 3.

During the return stroke of the piston 4, the pressure on the shank of the pusher from the side of the pressed mass is removed, and the pusher 11 under the action of the spring 14 returns to its original position. In this case, the spring 8 acts on the shut-off valve, which separates the axial channel 17 from the discharge line, which prevents the loss of the liquid preservative during the pressing process. As a result of repeated cycles, the bale is formed with the simultaneous and uniform introduction of a preservative into it.

The use of the proposed device on PS-1, B and K-453 balers for pressing various hay-straw materials in comparison with basic pressing devices makes it possible to compress the feed with a humidity of up to 40%, while ensuring a reduction in nutrient losses .
