Abstract

Use: the distribution of fertilizers on the spreading discs. The essence of the invention: improving the uniformity of fertilizer spreading. An additional tray divides the falling fertilizer streams equally into the upper and lower branches of the scraper conveyor. 4 il.

Description

The invention relates to the field of agricultural engineering and can be used for fertilizing the soil.

The aim of the invention is to increase the uniformity of spreading fertilizers by uniformly distributing them to the spreading discs.

In Fig.1 shows a diagram of the fertilizer spreader, General view; figure 2 - distribution device fertilizer spreader, top view; on fig.Z - section aa in figure 1; figure 4 - section bb in figure 1.

The fertilizer spreader contains a body 1 with a movable bottom (not shown), under which spreading discs 2 and 3 with blades 4 are placed on the upper surface and with a rotational movement mechanism (not shown) in the unloading zone, allowing them to rotate in opposite directions. parties. Spreading discs are placed in a horizontal plane.

Between the body 1 and the spreading discs 2 and 3 there is a distributor device in the form of a scraper conveyor 5, on the carrier links x 6 of which, for example chains, are fixed scrapers 7 groups with intervals between them, and the length of each interval is not less

the length of the scraper group7. The direction of movement of the conveyor 5 is perpendicular to the longitudinal axis of the body 1.

The scraper conveyor 5 is provided with guide trays 8 and 9, the tray 8 is placed under the lower branch 10, and the additional tray 9 - under the upper branch 11, at the end section 12. They are designed to collect fertilizer 5 that are convertible from the scraper 7 to the spreading discs 2 and 3, while tray 8 is for collecting fertilizers converging from the scrapers 7 of the upper and lower branches, and tray 9 is for compensating for this gathering of fertilizers, i.e. to ensure uniform fertilizer delivery to the spreading discs 2 and 3 of the lower 10 and upper branch 11 transport ra. The length of the tray 9 is chosen experimentally and has such a value that the disks 2 and 3 receive the same amount of fertilizer at each time point. The location of the additional tray 9 on the end section 12 of the upper branch 11 of the conveyor 5 ensures that the amount of fertilizer on it, which compensates for its descent from the upper branch to the lower branch.

Fertilizers from the body 1 with the help of the movable bottom are fed to the scraper conveyor 5 of the switchgear and get to the scrapers 1 of the upper branch

11 and at intervals between the scraper groups - onto the scrapers of the lower branch 10. Some fertilizers, including those from the scrapers 7 of the upper branch 11, come down and fall into the tray 8, and also a small part of them from the body fall into the tap hole 9.

The conveyor 5, moving in the direction perpendicular to the body 1, moves the fertilizers on the scrapers 7 and in the trays 8 and 9, while the upper branch 11 moves the fertilizers to the right and dumps them onto the spreading disc 3, and the lower branch 10 to the left and dumps them onto disk 2, in addition, the lower branch captures fertilizers on tray 8, and upper branch 11 captures fertilizers on additional tray 9 and dumps them on disk 3, due to the fact that some fertilizers from scrapers 7 top branches of conveyors 5 because of the transport goes into the tray 8, this number of fertilizers is compensated by the amount of fertilizer that tray 9 collects — it enters it from body 1.

The spreading discs 2 and 3, rotating in opposite directions, use the blades to spread the fertilizer sideways in the form of a strip,

Tray, located under the top

the branch of the conveyor of the distributor, at its terminal section compensates for the gathering of fertilizers from the upper branch to the lower branch of the conveyor, that is, it ensures equal supply of fertilizer to the spreading discs.
