Description

The utility model relates to agricultural engineering, in particular to the separating working bodies of root and tuber harvesting machines.

A device for separating root tuber crops from impurities is known [Copyright certificate RU patent No. 94800, IPC class. A01D 33/08, 2010], which contains a slide made in the form of an inclined conveyor, the endless conveyor belt of which has a working branch and a return branch with elastic fingers, a separating elevator and a conveyor for unloading root tubers. At the top of the slide, above the working branch, there is a bumper roller. Under the working branch of the slide cloth there is a shaking mechanism consisting of a roller mounted on a lever. The lever arm contacts a lug wheel located on the slide's drive pulley. The height and number of wheel protrusions are adjustable, and the shaking mechanism is designed to move along the slide surface. The lever is made of elastic material.

The disadvantage of the known device is the low reliability of the device due to increased wear of the shaking mechanism drive lever at the point of contact with the wheel with protrusions.

The closest analogue to the claimed one, adopted as a prototype, is the separating device of a root-club harvesting machine [Copyright certificate RU patent No. 216631, IPC class. A01D 33/08, 2023], consisting of a slide cloth, under which a shaking mechanism is installed, and the shaking mechanism is made in the form of a drive shaft with installed cams, each cam is equipped with rollers, and the rollers are fixed at an equal distance from the axis of rotation of the cam.

The disadvantage of the prototype is the low quality of work. Fragments of wet soil stick to the slide cloth and elastic fingers, and plant impurities and solid inclusions, such as stones, get jammed into the spaces between the elastic fingers and all this is drawn into the circulation along with the canvas, reducing the quality of separation of impurities from root tubers.

The technical result of the utility model is to improve the quality of work.

The technical result is achieved due to the fact that the elastic fingers on the slide fabric are arranged in longitudinal rows, the fingers of each row are offset relative to the fingers of adjacent rows by half the inter-finger distance in the row, and at the end of the slide, under the lower branch of the endless web along its entire width, a a rotating cleaning drum with elastic fingers that fit between the rows of endless blade fingers along their entire length.

This set of essential features ensures that the inventive separating device of a root and tuber harvesting machine has new properties that differ from the prototype.

Thus, the declared features of the utility model meet the “novelty” criterion.

In fig. 1 shows a diagram of the separating device of a root-club harvesting machine, side view; Fig. 2 - extension element A in Fig. 1, in fig. 3 - view B in Fig. 1 fragment of an endless roller coaster with elastic fingers.

The separating device of the root-club harvesting machine, consisting of threaded connections attached to the common frame of the separating elevator 3, an unloading conveyor 1, a slide 10 with an endless web 4 with elastic fingers 2 on it, a shaking mechanism 9 of the upper branch of the web 1, made in the form of a drive shaft 11 with installed on it there are 13 cams and 12 rollers on them, and the elastic fingers 2 on the slide canvas are arranged in longitudinal rows, the distance between the rows is 50 mm, the fingers of each row are offset relative to the fingers of adjacent rows by half the inter-finger distance in the row, and at the end of the slide, under the lower branch of the endless web along its entire width, a rotating cleaning drum 7 is installed on a common frame with elastic fingers 8 that fit between the rows of fingers 3 of the endless web 4 along their entire length.

The separating device of the root and tuber harvesting machine works as follows.

A heap of potatoes from the separating elevator 3 is fed to the canvas 4 of the slide 10. Under the canvas of the slide there is a shaking mechanism 9. When the drive shaft 11 of the shaking mechanism 9 rotates, the cams 13 located on it also begin to rotate and alternately influence the upper branch of the canvas 4 of the slide with 10 cams 13 s rollers 12. Thanks to the oscillatory effects of the canvas 4 of the slide 10, the potato 5, which has a rounded shape and is larger in width and thickness than the impurities, acquires additional mobility and rolls along the tops of the fingers 2 down the slide 10 onto the unloading conveyor 1. Impurities 6 in the form of residues plants and small and non-rounded soil fragments fall into the interdigital space and are carried up the hill. In the operating area of the cleaning drum, its fingers 8 enter the space between the rows of fingers 2 of the endless blade 4 over their entire length and remove impurities along with adhered soil. At the same time, canvas 4 is qualitatively cleaned of impurities, including adhering soil, and due to this, the quality of separation is improved.
