SU1631346A1 - Stand for studying the effect of operation of agricultural machines on soil - Google Patents

Abstract

The invention relates to testing equipment and can be used when conducting accelerated testing of the working bodies of tillage machines. The purpose of the invention is to expand the range of research by providing an opportunity to study the soil impact of various tillage workers. The stand contains a chute with soil 3, in the side wall of which there is a process window in the form of a screen 11 made of transparent material. The screen I is mounted in the process window by means of the casing 12, the casing 12 is installed in the latter with the possibility of movement relative to the trough in the vertical and transverse-horizontal directions. Outside the gutter, compartments for installation of photo and film equipment are mounted. The screen 11 can be installed both horizontally and vertically, 1C.p. f-ly, 4 Il. with $ (L

Description

on the soil of various soil cultivators, lighters 23. In compartment 22 for special working bodies.

On fkg 1 the test bench is shown, top view; in fig. 2 - section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 is a fragment of a cross section of a device with a horizontally positioned observation screen.

The stand for radiation impact on the soil of the working bodies of agricultural machines contains a frame 1, on which the chute 2 is mounted, filled with soil 3. On the sides 4 of the channel, guides (rails) 5 are fixed, on which a strain gauge cart 6 with working bodies 7 are mounted whose effects on the soil are being studied. In the adjacent section of the groove 2, in its side wall there is an opening in the form of a window, the contours of which form the angle of the channel bars 8 and 9, which are connected together between themselves and the guide rail 5 welds,

The grooved part of the channels 8 and 9 is placed in the brickwork of the bead 4 of the chute 2, Part of the opening in the wall of the chute 2 is closed by a shield 10 attached to the channels 8 and 9. In the other

The base 24 is fixed to a movie camera 25. On the basis of 24 there are also shelves 26 for accommodating transformers and other

15 filming devices. A magnetic starter 27 is mounted on the side wall of the compartment 22 with a push-button station 28 for switching on the illuminators 23 and the remote tensometric drive.

20 carts 6.

For visual assessment and registration of processes of interaction with the soil of the working bodies 7, having a drive, the screen 11 and the casing 12 are placed horizontally

25 (below the plane of travel of the working bodies). In this case, a light reflecting plate 29 (or a mirror) is installed in the casing 12, which is placed in the casing under the

The stand functions as follows.

Before the tests on the strain gauge trolley 6, a working body is installed, for example, a flat-cutting paw, and the trolley is moved to its original position. Movie and photo equipment is prepared. Then the cart 6 is driven

mi, and the walls 14 and 15 - metal sheets. The transparent screen 11 is made of double-layered glass, for example, the outer layer is made of window glass, and the inside is made of plexiglass.

A coordinate grid 16 with cell dimensions of 50 × 50 mm is applied on the plexiglass. Screen 11 is fixed in the frame 13 of the casing 12 by means of screws 17. On the side vertical walls 15 of the casing 12 there are slots 18 that extend in the direction perpendicular to the window-opening plane. Screws 19 are installed in the slots for fastening the casing 12 into the threaded holes 20 of the vertical channels 8 of the opening window. Thus, the casing can

inside the gutter into the soil mass for a distance, providing observation of the impact of the working body.

With the passage of an organ in front of a screen of transparent material, the process of interaction of the working organ with the soil is fixed. At the conclusion of the experiment, a film appears and then the said pro- cessing process is decrypted. Due to the coordinate grid 16 and predetermined values, for example, the angles 10 of the sharpening angle E, the magnitudes of the flaking angle E, the particle flight speeds and their trajectories, as well as the flux of the plaster, the occurrence of erosion dangerous particles, their distribution in the soil and etc.

Claims (1)

Claim When testing rotational, in fact, active working bodies with the power of a screen I 1 placed horizontally below the working bodies in the vein mass, one can get a picture of the working bodies' impact on deeper soil layers, which cannot be done when observing the operation of machines from above or from the side. 1, A stand for studying the impact on the soil of the working bodies of agricultural machines, containing a gutter with soil, in which there is a side technological window, and an observation screen made of transparent material, characterized in that the purpose of expanding the range of studies by providing the possibility of * 'studying the impact on the soil of various tillage working bodies, the observation screen is placed inside the trench in the soil mass and is equipped with a casing mounted in the technological window and installed with the possibility of re room relative to the gutter in the vertical and transverse-horizontal directions, a. on the outside and the technological window of the gutter, compartments are mounted to accommodate photo and film equipment. The stand on π, 1, I distinguish with the fact that the screen for the observation is placed horizontally in the gutter Figure 1 δ Fig.Z
