Abstract

FIELD: agricultural engineering. SUBSTANCE: device has a frame carrying front and rear shafts. Radial cutters are secured on the shafts, and the latter are in engagement due to toothed or lantern gear transmission (transmission ratio 1: 3). The front and rear shafts are at an angle relative to each section are plates one-direction-bent from the longitudinal vertical plane to follow a spherical surface. EFFECT: higher tillage quality. 5 dwg

Description

 The invention relates to agricultural machinery, in particular to implements for tillage on ridged and flat surfaces.

 It is known a tool for mulching the surface of the soil, containing a frame on which horizontally mounted front and rear shafts with sections of radially directed cutting elements fixed to them, while the shafts are interconnected by a mechanical transmission with a gear ratio of 1: 3 [1].

 The disadvantage of this device is the low quality of work, high energy and metal consumption, the inability to process ridges.

 The purpose of the invention is improving the quality of tillage.

 This is achieved by the fact that the front and rear shafts are located at an angle to each other and to the transverse vertical plane, and the transmission connecting the shafts is made in the form of a tooth or pinion gear, and the cutting elements in each section are made in the form of curved on a spherical surface in one direction from the longitudinally vertical plane of the plates.

 In FIG. 1 shows a device, a top view; in FIG. 2 is a view along arrow A in FIG. 1; in FIG. 3 is a view along arrow B in FIG. 1; in FIG. 4 - working bodies of the front shaft; in FIG. 5 - the same as the rear shaft.

 The device includes two shafts - drive 1, driven 5, bearings 3, bevel gear 4, working bodies 2 and 6, bevel gear 7, hermetic housing 8, bracket 9, cylindrical hinge 10, bracket 11, cross member 12.

 An eight-knife working body 2 (5 pcs) is mounted on the drive shaft 1. The ends of the shaft are supported by two bearings 3. A bevel gear 4 is fixed to the shaft, which is meshed with a small bevel gear 7 of the driven shaft 5, on which five four-knife working bodies 6 are mounted.

 Bevel gears for protection against dust are placed in a sealed housing 8, which is also a rigid connection of the drive and driven shafts, on which the bracket 9 for installing the cylindrical hinge of the suspension 10 is fixed, by means of which the device is hung on the frame. On the opposite side, brackets 11 are connected to the bearing housings, interconnected by a cross member 12, on which a cylindrical hinge of the suspension 10 is fixed.

 The device operates as follows. When the device is moving, the working bodies 2 of the front shaft 1 are buried in the soil and, rotating with sliding, raise the soil, throwing it up. The rear shaft 5 with the working bodies 6, rotating three times faster than the front one, receives soil coming from the working bodies of the front shaft, additionally loosens it and evenly distributes it on the treated surface, mulching the soil to a predetermined depth.
