SU465576A1 - A device for sampling pulps from tubers - Google Patents

Description

one

The invention relates to an agricultural technique, namely, devices for sampling pulps from tubers for subsequent chemical analysis.

Apparatus for obtaining samples of pulp are known, including a receiving hopper with a set of circular saws and an opening for the exit of the material to be sampled, as well as a collection of samples.

However, the pulp received on these devices and entering the collection contains, along with fine particles, a large number of large particles and tops of the foliage that prevent the subsequent chemical analysis and distort its results.

The purpose of the invention is the selection of sample particles that are more uniform in size.

This is achieved by the fact that the proposed device is equipped with a movable perforated gate located in front of the set of circular saws in the direction of the trajectory of the particles thrown by them.

In this case, the sample collection can be mounted on a movable support and installed inside the drum.

In addition, the flap is made in the form of an endless belt, forming the side surface of the drum, inside of which is installed a tubular manifold for flushing

liquid, and on the outside of the drum brushes mounted.

Pa drawing shows a diagram of the proposed device.

The device comprises a housing 1, on which a receiving hopper 2 is mounted, a set of disk saws 3 mounted on a horizontal shaft 4, a deck 5 with slots for disk psh: as well as a separator made in the form of petals

forged drum 6.

The drum b is installed just before the set of circular saws in the direction of the flight path of the particles thrown by the saws and covers the neck of the collector 7,

mounted on the conveyor 8 periodic action.

A collector 9 with holes for flushing fluid is installed on the inner side facing the collector, the side of the drum 6,: i

brushes 10 - on the outside.

For removal of flushing fluid and large particles of tops, roots and roots into the sewage system, it has a receiving tank 11. The device works as follows.

Tubers or roots through the receiving hopper 2 are attached to the rotating saws 3 and cut into pieces. Parts of the roots, cut with circular saws, are moved along deck 5 and removed from housing 1,

and the pulp formed during cutting through

3

the slots in the deck are dropped onto the drum 6. Fine particles of pulp penetrate through the openings of the drum and enter the collection 7, while larger particles, and the particles of tops and roots are trapped by the drum and removed from the housing.

To clean the rotating drum from sticking particles, washing fluid is supplied through the collector 9. The remains of particles are cleaned from the surface of the drum with brushes 10 and rinsed with water into tank P.
