Description

The proposed utility model relates to methods and means for determining the quality of the technological process by tillage machines.

A device for determining soil crumbling by tillage machines (patent for utility model 151 095 Russian Federation "Device for determining soil crumbling by tillage machines" [Text] / EV Bondarenko, VA Serdyuk, VV Serdyuk), containing a base having an opening in which a frame of cylindrical shape is installed, in the upper part of which there are two handles for its rotation.

The process of determining soil crumbling by tillage machines is as follows.

A pallet is installed in the rotating frame, a set of sieves with hole diameters corresponding to the sizes of soil fractions is installed on top of it in order of increasing hole diameters. The selected sample is poured onto the upper sieve. Holding the frame handles, they perform several rotational reciprocating movements clockwise and counterclockwise until the soil is completely divided into fractions when passing through the sieve. Then the contents of each sieve are weighed. The process is repeated for each subsequent sample.

A disadvantage of the known design of the device is that the installation of sieves and a pallet in the inner space of the frame is made from above. To weigh the contents of each sieve, they have to be excavated through the top hole of the frame, which is rather laborious, given the presence of soil in the sieves.

In addition, for better sieving of moist soil, in addition to rotational-vibrational movements, it is necessary to produce vertical back and forth movements of the frame.

The purpose of the utility model is to reduce the cost of manual labor and the time spent on sifting soil fractions through sieves.

To ensure this goal is proposed the design of a device for determining the crumbling of soil by tillage machines. The proposed device for determining the crumbling of soil tillage machines shown in the drawing.

The proposed device consists of a base 1 having a hole in the center into which a rotating cylindrical frame 2 is mounted, made of vertical and horizontal rods that are welded together, and its part 3, equipped with a clamp 14, is removable, which provides convenient installation into the inner space of the frame and removing the pallet 4 and the set of sieves 5 from it.

A pin 6 is welded to the center of the bottom of the frame. When installing the frame in the hole of the base, two compression springs are installed on the pin: one upper 7 to the base, the second lower 8 to the bottom of the base, which provides vertical mobility to the connection of the frame pin in the hole relative to the base. The bottom pin is fixed with a nut with a cotter pin 9.

To give the rotating frame vertical movements from the bottom of the base, a pedal 10 is installed, the front of which abuts against the end of the journal.

In the upper part of the frame there are two handles 11 for its rotation. A handle 12 is welded to the front of the base to move the device to the sampling location using a pair of wheels 13 mounted on the base.

The device operates as follows: a pallet is installed in the inner space of the frame with the removable part removed, a set of sieves with hole diameters corresponding to the sizes of soil fractions is installed on top of it in order of increasing hole diameters.

Insert the removable part into place and securely fix the frame. The selected sample is poured onto the upper sieve. Handles for rotating the frame make several rotational movements in both directions. At the same time, they press the pedal with the foot, giving vertical oscillatory movements to the frame due to compression and extension of the springs. After that, the handle for moving the device makes oscillatory movements until the soil is divided into fractions through a sieve. Then the contents of each sieve are weighed and so on for each experiment.

The proposed device for determining soil crumbling by tillage machines allows you to:

- eliminate the influence of the human factor and improve the accuracy of measurements;

- to improve the quality of sample processing when divided into fractions, due to the possibility of providing the same conditions when sifting the soil for a number of samples;

- reduce the complexity and reduce the duration of the separation of the soil into fractions for each experiment;

- reduce the effect of soil moisture on the quality of the separation of the soil into fractions.
