Abstract

The invention relates to earthmoving machinery and can be used to mechanize the gathering of bulk materials, in particular for excavating soil in protected ground. The goal is to increase the reliability of work and the efficiency of the cutting process. The screw working body includes housings 1 installed on the frame with screws (W) 3 housed in them with cutting elements (knives) 4. The latter are fixed on shafts 5 installed parallel to Sh3 shafts. The ends of the shafts 5 have gears-satellites 7 meshed with a fixed gear 8. The gear wheel 8 is rigidly attached to the fixed casing 1. When rotating W 3 together with the shafts 5, the latter simultaneously rotate around their axes due to rolling the gear-satellites 7 on stationary gear wheels 8. With further progress of the unit, the knives 4, rotating, cut into the treated soil layer, loosened and throwing it into the space between the turns of W 3.

Description

The invention relates to the land-tilling machine building of agricultural production and can be used for mechanization of scooping up loose materials, in particular, for excavating the soil in protected ground.

The purpose of the invention is to increase the reliability and efficiency of the cutting process.

Fig „1 shows a screw working body, a general view of fig 2, 2 - a screw with a drive.

The screw working body of the pick-up conveyor consists of an axial shaft installed in the casing 1 in the form of a pipe 2 with a screw 3, between the turns of which there are loosening knives C,

mounted on parallel axis 20 screw 3 shafts 5, which are located in the openings of the turns of the screw 3 through closed and closed bearings 6. The shaft 5 is rotated by fixing gears 7 at the ends of each shaft gearing with a stationary gear wheel 8, the Gear wheel 8 is attached to the fixed casing 1 coaxially with the axial tube 2. Number of wahs zo

on the auger is set depending on the translational speed of the unit, the speed of rotation of the auger and the depth of tillage.

The working body works as follows.

In order to excavate the soil, the unit with the working bodies approaches the soil to be transported, then the drive 9 of rotation of the scooping screws 3 (right and left) and the drive of the intake device 10 (screw or bucket conveyor) are turned on. During the rotation of the augers 3 together with the D5 shafts 5 mounted on them, the latter simultaneously rotate around their axes by rolling the gears-satellites 7 along the fixed gears 8 "Together with the shafts 5 the loosening knives C, rotated on them, also rotate

With further progress of the assembly, the knives, simultaneously rotating around the axis of the screw 3 (in the direction of arrow A) and the axes of the shafts 5 (along arrow B) 7, are cut into the treated soil layer, loosening and throwing it into the space between the turns of the screw 3. Screws, in turn move the already loosened soil (along arrow C) to the intake device 10, which unloads the soil (along arrow D) into the vehicle.

During the operation of the screw, the rotating knives, located in the casing zone, actively cut the soil stuck to the inner surface of the casing, thereby eliminating the occurrence of additional resistance to the screw rotation.

If necessary, the speed of rotation of the shafts with knives, at a constant speed of rotation of the auger, is adjusted by changing the gear ratio of the removable gear-satellite and gear.

The process of work of the working bodies of the screw working body is continuous,
