Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to improve the quality of manure grinding. When feeding manure auger 4 to the metering valve 10, the manure is first ground before the metering valve 10 using radial cutting plates 12 and fixed cutting plates 13, then the manure is ground after the metering valve 10 using radial cutting plates 12 and fixed cutting plates 13, thus the manure is ground in two places successively. The metering valve 10 controls the dose of manure with vertical movement by reducing the bore between the U-shaped cut-out 11 and the screw shaft 4. 1 h. n. f-ly, 5 ill.

Description

FIG. 2

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for spreading liquid and semi-liquid manure.

The purpose of the invention is to improve the quality of grinding manure.

FIG. 1 shows a diagram of the device, a longitudinal section; in fig. 2 - metering valve, front view; in fig. 3 - dosing valve; in fig. 4 is a section A-A in FIG. 3; in fig. 5 is a view of a screw with a bent part of the blade.

The device contains a reservoir 1, a shaft 2 with blades 3 of screw 4. At the end of shaft 2 there is a blade rotor 5 placed in an opening glass 6. Fenders 8 unlocked by a discharge pipe 7 of the screw 4 of the screw 4 are bent in the direction opposite to the direction of rotation of the screw 4 The blade 8 of the screw 4 has a cut-out 9 for passing the metering valve 10. The metering slide 10 has a U-shaped cut-out 11 for grasping the shaft of the screw 4 when lifting and lowering it. The interrupted blades 8 of the screw 4 on either side of the metering valve 10 have three radial cutting plates 12, of which one plate 12 is attached to the edges of the interrupted blade 8 of the screw 4, and the other two are attached to the screw shaft 4 at an angle of 120 °. The edges of the U-shaped notch 11 of the metering valve 10 on both sides are edged with fixed cutting plates 13. Under the discharge pipe 7 there is a collection of 14 impurities.

After loading the tank 1 with manure and transporting it to the fertilized field to the shaft 2 in the working movement of the spreader, rotation from the tractor's power take-off shaft (not shown) is reported. The blades 3 of the shaft are mixed and fed manure to the screw 4. The blades 8 of the unshielded part of the screw 4 during rotation create a centrifugal force that throws to the tank wall

large non-milling manure impurities, after which they enter the collection of 14 impurities. Next, the manure is fed into the discharge port 7 of the screw 4, passes through the metering valve 10, while the remaining impurities are crushed by the cutting plates 12 and 13. The crushed manure mass is directed to the rotor blades 5. The glass 6 is opened, the manure is discarded and distributed throughout the field. A collection of 14 impurities is periodically discharged from impurities. After unloading the tank 1, the bowl 6 is closed, the tractor's power take-off shaft is turned off and the spreader follows the next load.

Claims (2)
