The disadvantage of these workers

The bodies of pneumatic fertilizer spreaders are the complexity of the structure of the ejector socket, which is rotatable with the help of a gear rack and pinion, and that it is necessary to have a seal between the latter and the split duct. In addition, at small angles of inclination of the ejector to the horizon plane, the turning part of this device is relatively cumbersome, and it is technologically advanced to manufacture, which complicates the manufacture and increases the cost of the whole structure.

The purpose of the invention is to increase the operational reliability of the working opiiQHa.

It is connected with the hydraulic cylinder of the rotary valve.

In addition, the lower opening of the loading funnel covers both throats of the ejector sockets, and in the middle part of the loading funnel pivotally at: - hacked plate, which is connected to the hydraulic cylinder of the rotary valve.

FIG. 1 shows a working body of a pneumatic raabre.yvyvatel fertilizer, top view; in fig. 2 - the same, side view; in fig. 3 — one embodiment of the feed funnel, side view; in fig. 4 - the same, top view; in fig. 5 - on the rial t the execution of the rotary feed hopper, side view.

The working section of the pneumatic spreading of fertilizer stubs contains a fan 1 (Fig. 1), the discharge cavity of which is connected to a split into the left 2 and right 3 branches by an air duct that is mounted on the frame, the ends 4 and 5 of the split air duct are turned towards each other, parallel to each other in the longitudinal and transverse directions and narrowed to the formation of the ejecting nozzles, which later pass into the sockets 6 and 7 of the ejectors with their loading necks 8 and 9. The latter are installed so that they have They run along the longitudinal axis of the spreader (Fig. 1). The feed hopper 10 is filled with a movable one and held by sliders 11 in guides 12. Hydrocylinar 13 is attached to loading hopper 1O. Stem 13 is connected by lever 15, heavy 16 and lever 17 to rotary valve 18 installed in the duct forking branch. The working body is designed so that the loading openings of the ejectors with a movable loading hopper 10 are located under the discharge window of the pit conveyor 19 (FIG. 2), the front wall 20 of which is equipped with a spigot gate 21. The discharge end of the conveyor 19 is equipped with a housing 22. hopper (fig. 3) hopper 23 for loading material into the ejectors is fixed, located under the discharge end of the feed conveyor 19 and covers simultaneously both boot throats of ejectors, in a fixed feed hopper 23 (figs, 3 and 4) in its central part a transverse flap 24 is installed, which rotates on the axis of rotation 25. The pivot axis 25 of the flap 24 pH4aroivf 26 is connected by a hinge but with traction 27, which In turn, it is connected to the pull 16 (fig. 3, 4 and 1). With the third possible constructive implementation of the loading funnel (fig. 5) the loading funnel 28 is suspended by rigid rods 29 on the joints of the SO and the connecting rod 31 is pivotally connected 13 of the hydraulic cylinder 14 (FIG. 5, 1 and 2). This loading mouth of the funnel is located, as in the previous cases, under the discharge opening of the feed conveyor 19, the front wall of which is supplied with a gate valve 21 (Fig. 5). Working body pneumatic section. Fertilizer fertilizer works as follows. In accordance with the direction of scattering of fertilizers, which is determined from the direction of the wind relative to the direction of movement of the unit, the rod 13 of the hydraulic cylinder 14 movable loading funnel 10 on the sliders 11 in the guides 12 moves to a position where its swelled hole completely coincides with one from the charging ports 8 or 9 sockets of 6 or 7 ejectors (Fig. 1). For example, when spreading fertilizers to the left in the direction of movement of the aggregate, the feed hopper 10 is aligned with the feed neck of the ejector socket 6 (Figs. 1 and 2). In parallel, the lock 13 through the lever 15, t gu 16 and the lever 1 7 rotates the valve 1, and closes the nm branch 2 section | anvaya duct. With the fan 1 turned on, the air flow through the branch 3 of the duct is fed to the socket 6 of the ejector. When the material (mineral fertilizers) feeds are turned on to feed the sports car 19 (Fig. 2), which is dispensed by the installation height of the gate valve 21 on the wall 2O, the scatter material from the conveyor 19 enters the feed funnel 1O, from where the bottom spills into the located under it, the charging neck 8 of the bell 6 of the ejector (FIGS. 1 and 2) .- Under the action of an ejecting air stream coming from the ejection nozzle formed by tapering before the charging neck 8 of the end 5 of the bent portion of the duct branch Neural fertilizers are mixed with air, accelerated along the length of the socket 6 of the ejector, thrown out. and scattered across the surface of the field to the left as the unit moves. Since the ejector allows the material to be injected through a feed funnel in communication with the atmosphere, the joints of the movable feed funnel 10 and feed neck 8. do not need special seals, except those that are placed in the installation area of the valve 18, to reliably close one of the duct branches. When spreading mineral fertilizers to the right with respect to the direction of movement of the unit, the feed hopper 10 on the slides 11 Along the guides 12, the rod of the hydraulic cylinder 14 moves to a position in which its discharge opening completely coincides with the opening of the ejector mouth 7 of the ejector (Fig. 1 and 2, dashed lines). In parallel with this rod 13 of the hydraulic cylinder 14, through the lever 15, the tu 16 and the lever 17 rotates the valve 18 to a different position, thus blocking the branch 3 of the split air pipe. I, .. The air flow from the operating fan 1 through the branch 2 of the duct is now supplied to the socket 7 of the ejector. With the supply of mineral fertilizers turned on, the material being sown through the outlet opening of the charging funnel 10 is now fed into the loading neck 9 of the socket 7 of the ejector. Under the action of an ejection jet coming from a nozzle formed by narrowing the end 4 of the curved section of the branch 2 of the duct and located in front of the neck 9, fertilizers in the neck 9 are mixed with air, accelerated along the length of the socket 7 of the ejector. are thrown out and scattered on the front: right side along the unit's airway. If the working body of the spreader is equipped with a non-returnable loading funnel with a throw-away wall, the construction of which is shown schematically in FIG. 3 and 4, he works in the best way. When moving the fan from the operating fan 1, for example, to the ejector socket 6 by the rod 13 of the hydraulic cylinder 14, the lever 15 is rotated counterclockwise to the extreme position. Moving the lever 15, pushing 16 towards the fan 1, intercepts the lever 17 with a valve 18 by means of a valve 17 by means of a valve 17 (fig. 1 and 4). associated with thrust 16, this movement of an IGBKiecre pull with thrust 27 rotates the flap 24 of the hopper 23 to the position shown in FIG. 3. And 4 by a solid line. In such a position of the flip valve 24, the seeding machine from the feed conveyor 19 rolls over its surface into the filling mouth of the bell 6 of the ejector. In it, they are mixed with the supplied hood by an ejection jet of air, accelerated, thrown out and scattered over the surface of the field. When the direction of dispersion is reversed by the rod 13 of the hydraulic cylinder 14, the lever 15 rotates clockwise to its other extreme position. At the same time, it mixes the cable 16 in the direction of its removal from the fan 1 and through the lever 17 by valve 18 overlaps the branch 3 of the duct, ensuring air supply to the socket 7 of the ejector. During the movement of the cable 16, it turns the reversing flap 24 on the axis 25 to another one through the rod 2 by the lever 26, which is shown in FIG. 3 and 4 with the stroke of a pin. The sowing material from the conveyor 19 is rolled along the flap 24 of the flap 24 into the loading neck of the bell of the 7 ejector, and the working body in a similar way spreads the fertilizer on the other side of the spreader. When the loading hopper is poured out (fig. 5), the working body of the feeding spreader works in the same way as its work with the movable loading hopper. For example, when air is supplied to the socket 6 of the ejector, rod 13, extending from hydraulic cylinder 14, through lever 15, bar 16, pin-17 17, valve 18 blocks branch 2 of the air duct, providing air through branch 3 (Fig. 1). Since the ha 31 is pivotally connected to the rod 13, when it moves, the unloading hole of the pumping hopper 28 (Fig. 5) is combined with the loading neck of the ejector socket 6, ensuring the flow of the material to be sown. When air is supplied to the socket of the electric motor 7, the rod 13, having reversed to the original direction, twists the branch 3 of the air duct and simultaneously rotates the feed hopper 28 of the pulley 31 into the position at which the material to be sown is fed to the ejector mouth 7 (Fig. 5, dashed lines). The proposed working body of the pneumatic fertilizer spreader, as compared with the known ones, is extremely simple in design, eliminates the need for the construction to have significant moving masses of parts of the working body. The use of a predokvennogo working body gives an economic effect in comparison with the known about two rubles per hectare of fertilized area of the floor. 2Q / g
