Plant hiller

The subject of the invention is a plant ridger, especially potatoes, which can be used in state and private farms in plant production and plant breeding stations.

The so far known and used hillers are built as attached, for example, horse-mounted and mounted - for tractors. The working element of the ridger is ridging bodies, whose task is to scoop loosened soil onto the lower parts of the stalks. This treatment is most often combined with the destruction of weeds in the inter-row spaces. The soil scrape on the lower parts of the stalks occurs as a result of soil movement on the working surfaces of the covering bodies moving with the tractor. With too dense rows of plants, and in the later stages of their development, it is impossible to scrape the soil on the lower parts of the stems. Plants break or are covered with the ridger as a result of the hiller's movement.

The hiller according to the invention has at least two plowshares over which star projectors are placed in the cover. In the lower part of the cover, there are screens to immobilize the soil for the outer rows of plants and channels to cover the covered plants. On the other hand, in the upper part of the cover, there is a screen for additional soil breaking and chambers directing the soil between the rows of plants. In front of the chambers there are plant scrapers that spread the stalks sideways with weeding knives, and behind these chambers there are knurls raking the soil on the lower part of the stalks.

The construction of the ridger according to the invention ensures the destruction of weeds in the inter-rows and the covering of plants even in the later stages of their development, without damaging and breaking the plant stems, as well as plants planted in compact rows.

The subject of the invention is presented in the embodiment in the drawing, in which fig. 1 shows the ridger in cross-section along the line A-A marked in fig. 2, fig. 2

- top view.

The ridger consists of two plowshares 1 over which two star projectors 2, driven by the tractor power take-off shaft, are positioned. 2 star projectors are placed in cover 3,

155 617 which is also a channel for the thrown out soil. In the lower part of the cover 3 there are screens 4 for directing the soil to the outer rows of plants and channels 5 for covering the covered plants. On the other hand, in the upper part of the cover 3 there is a screen 6 which serves as an additional break-up of the soil and a chamber 7 for falling soil between the rows of plants. In front of the chambers 7 there are plant scrapers 8 that spread the stems sideways with weeding knives 9. On the other hand, behind the chambers 7 there are knurled wheels 10 which scrape the soil on the lower part of the stems. The whole is mounted to the support frame 11, on which there is a toothed gear 12 and chain gears 13 and 14 for transmitting power from the tractor power take-off shaft to star projectors 2.
