Abstract

The invention relates to stands for testing earth moving machines and reduces the time required for testing. To do this, in the stand, the soil supply mechanism is made in the form of a multi-bucket conveyor (T) 10 and installed equidistantly relative to the horizontal endless belt (BL) 9.. Along the lower branch of T 10 there is a container with soil in the form of a curved tray (L) 1. A leveling and sealing body 5 and a humidifier 6 are installed above BL 9. Soil from L 1 is transported T 10 and unloaded onto BL 9. At the same time the ground is moistened the humidifier 6 is leveled and compacted by leveling the body 5. Next, the ground moves in the direction of the working body 4. The ground above the working body 4 falls into L 1. From L 1, the soil enters again to BL 9, etc. .

Description

The invention relates to stands for testing earth moving machines, and more specifically fljjn testing earth moving, soil tillage machines and their working bodies.

The purpose of the invention is to reduce the time of testing.

FIG. 1 is a diagram of the stand in FIG. 2 - the same section.

 The test bench for earth-moving machines contains a ground tray 1, a drive station 2 and a frame system 3, a working body 4 mounted on the frame and mechanisms for preparing the soil for testing, namely a leveling and sealing body 5 and a humidifier 6. Drive station 2 is kinematically connected Zana with leading sprockets 7, rigidly mounted on one shaft 8 of the internal belt 9 (endless belt) and external multi-bucket 10 conveyors, which are equidistant and installed in the axial direction of the soil tray 1 on their frame system 3, the axial line of which is concentrically curved relative to the asterisks of the conveyors 9 and 10. The stand for testing the machines and their working bodies works as follows.

Ground is poured into the ground tray 1, the drive station 2 is activated, which transmits the torque to the shaft 8 with the leading sprockets 7 of the inner belt 9 and the outer bucket 10 conveyors. T {) is assembled by an external scraper conveyor 10, unloaded onto an internal transporter 9, leveled, compacted leveling-up57428

the body 5 is humidified by the humidifier 6 and moves in the direction of the working body 4.

The accumulating soil on the inner 5 conveyor 9 in front of the working body 4 is turned and dumped past the belt into the dirt tray 1, from which it is continuously transported by the external bucket conveyor 10 on O the inner conveyor 9.

When testing the working device with the base machine, the latter is installed on the inner belt; the conveyor 9. At the same time, the conveyor belt 9 and the machine under test are simultaneously set in motion, whose linear velocities are equal and oppositely directed. 20
