Description

(54) SOIL PROCESSOR

I

The invention relates to the field of agricultural engineering, namely, c. technical means for laboratory field tests and research of machines for deep and surface tillage.

The closest in technical drying and achievable effect to the present invention is a device for sampling soil, consisting of, from the frame, bucket and drive mechanism 1.

The soil sampling is carried out by pressing the bucket into the arable layer, removing the soil from the side section and hydraulic cylinder from one section of the bucket, lowering the cover-bottom and bringing it under the other section of the bucket.

Such a device design solves the problem of preserving the fractional composition of a soil sample only partially. The reaction of the forces arising from the removal of soil from one section of the scoop would have to be perceived by the tractor on which this device is hung. However, due to the presence of backlash in the hinge system and transmission of the tractor, this reaction initially affects the soil sample, shifting it, and thereby violating its fractional composition.

The aim of the invention is to eliminate this drawback and improve the quality of soil sampling.

The goal is achieved by the fact that the sampling bucket is made in three sections, the middle section is used to take a soil sample, and the front and back sections are auxiliary and prednaznoy10 started to bring the two halves of the bottom under the soil sample. In this case, the forces that occur when the soil is removed from the extreme sections are oppositely directed and balance each other. Impact on soil test while

15 is excluded.

FIG. 1 shows the proposed sampler, a general view; in fig. 2 - bucket, longitudinal vertical section.

The sampler consists of a frame 1, a three-section bucket 2, fixed 3 and

20 movable 4 front and rear walls of the bucket, mechanisms of the movable walls 5 of the drive with a hydraulic cylinder 6. The sampler is hung on the tractor's hydraulic 7. In the side walls of the sampler there are upper 8 and lower 9 longitudinal grooves, as well as vertical grooves 10. Movable front and rear walls the bucket in the lower part is hingedly connected with the bottom halves II, which have rollers 12 sliding in vertical grooves. The lower part of the vertical grooves is curved and has guides 13 of switching mechanisms that serve to change the direction of movement of the rollers 12. In the upper grooves are guides 14 that are rigidly connected to the moving front and rear walls and to the drive mechanism.

The sampler works as follows.

In the initial state, the movable anterior and posterior walls are led to the non-movable, and the halves of the bottom, using the rollers 12, which slide in vertical grooves, occupy a horizontal position, and the rollers fall into the lower horizontal grooves. Then the front and rear walls return to their original state, and the bottom halves are brought under the middle section of the KOBura, i.e. under the soil sample. After that, the tractor’s hydraulic attachment is raised and the sample is removed from the soil. The sample is poured for subsequent analysis. For this, the front and rear walls are moved apart, the bottom halves are dispersed, freeing the sample. To bring the sampler back to its initial state, the guides 13 are lowered, blocking the horizontal grooves, and the rollers 12 when moving the moving walls to the fixed ones enter vertical grooves, lifting the bottom halves.
