Abstract

The invention relates to agricultural machinery. The aim of the invention is to reduce the loss of mineral fertilizers. A shut-off valve 22 is installed in the longitudinal channel 17 of each rod. A locking mechanism is installed in the control line of the hydraulic cylinders for rotating the operating element and driving the metering pump, kinematically connected with the body of the loader boom when it is folded. During operation of the device, the fluid is injected into the pipeline 10 and further into the channels 17 and 18, and through the nozzles 19 into the organic fertilizer. In this case, the fluid opens the valve 22, overcoming the resistance of the spring 23. After the fertilizer is injected, the fluid pressure disappears, the valve 22 closes under the action of the spring. The locking mechanism plays the role of disconnecting the cylinders for the period when the injection device is shut down. 6 Il. "

Fig. M The invention relates to agricultural machinery, in particular to devices for the preparation of organic mixtures. The purpose of the invention is to reduce the loss of mineral fertilizers. FIG. 1 shows the device, a general view; in fig. 2 - diagram of the drive of the metering pump; in fig. 3 - working body; in fig. 4 rod; in fig. 5 is a section A-A in FIG. four; in fig. 6 is a diagram of the locking mechanism: the cavities of the hydraulic cylinders are connected (a), the cavities of the hydraulic cylinders are separated (b). The device for preparation of the organic-mineral mixture contains a vehicle 1, on the frame of which a grabber loader is fixed, containing, having rods 2 and jets, a working body 3 with a hydraulic cylinder for its control 4. On the vehicle 1 a container 5 is also fixed for liquid mineral fertilizers and installed In the form of a plunger pump 6, a metering device, which is driven by the hydraulic cylinder 7 through a double-arm lever 8. The cavities of the hydraulic cylinders 4 and 7 of the working body control and the metering unit are connected to each other autlically. The container 5 is connected by a pipe 9 to a plunger pump 6 and then by a pipe 10 to rods 2 of the working member. The plunger pump 6 has a suction 11 and a discharge 12 valves, and its rod is connected to the slider 13 of the two-arm lever 8 having a re-adjusting screw 14 fixed on the hinge 15. The rods 2 have lugs 16 (Fig. 4), as well as longitudinal 17 and transverse 18 channels with nozzles 19. Pipeline 10 is connected to the rods by means of a bar 20 and fittings 21, having shut-off valves 22 inside (fig. 4) with springs 23. On pressure hose 24 (fig 2) connecting the hydraulic cylinders 4 and 7, a locking mechanism is installed, made in the form of a cork valve 25, kinematically in bound to the loader boom body. The device works as follows. The container 5 is filled with a solution of mineral fertilizers. The working device of the device captures a portion of organic fertilizer, lifting the boom from the main mass and lifting the boom for loading. In this case, the pump.m. 6, using the hydraulic cylinder 7, liquid fertilizers are injected into the pipeline 10 and further into the channels 17 and 18, and through the nozzles 19 into the organic fertilizers. When passing through Shtucer 21, the fluid opens the valve 22, overcoming the resistance of the spring 23. After the injection of liquid mineral fertilizers into a portion of organic fertilizers, when the fluid pressure disappears, the valve 22 under the action of the fuji 23 closes the opening in the nozzle, preventing spontaneous outflow of fluid from the hose system. With the next injection of liquid fertilizers, the valve 22 opens again under their supply, and closes at the end of the discharge. The locking mechanism 25 plays the role of disconnecting the cylinders 4 and 7 for the period when the injection device is shut down. This happens the same way. The cork speck 25 (Fig. 6) has two extreme positions: open and closed. On the other hand, during operation of the device, two characteristic positions can be distinguished, the upper one when the working body is unloaded (i.e. when it is necessary to carry out the injection) and the lower one when organic fertilizers are cleaned up during repeated boom turns and the injection is not desirable. In favorlapy, the cork valve is made by the body of the loader boom. In the lower position the valve is closed, in the upper one it is open. In the lower position, the pressure slag 24g is blocked, and consequently, the drive liquid does not enter the hydraulic cylinder 7. The invention The device for cooking; 1 organic-mineral mixture according to ed. St. 1099867, characterized in that, in order to reduce the loss of mineral fertilizers, a shut-off valve is installed at the inlet of the longitudinal channel of each stem of the working member, and the hydraulic cylinders for turning the operating member and the drive of the metering pump are separated by a stop valve, kinematically connected with the body of the loader boom when it is folded.  0m j distributor I1 H distributor FIG. 2 ten Fig.Z Aa 21 21 FIG. five but 2C 25 one
