(54) РАЗБРАСЫВАТЕЛЬ МИНЕРАЛЬНЫХ УДОБРЕНИЙ(54) MINERAL FERTILIZER SPREADER

II

Изобретение относитс к сельскохоз йсгаенному машиностроению, в частности к разбрасывател м минеральных удобрений по поверхности почвы.The invention relates to agricultural machinery engineering, in particular to mineral fertilizer spreaders on the soil surface.

Известен разбрасыватель минеральных удобрений , содержащий тек с резиновым кольцом , взаимодействующим с роликом, при этом на внешней стороне диска установлены лопасти , заключенные в кожух с выходным отверстием , и механизм привода (1 .Known mineral fertilizer spreader containing tech with a rubber ring that interacts with the roller, while on the outer side of the disk the blades are installed, enclosed in a casing with an outlet, and the drive mechanism (1.

Известен разбрасыватель минеральных удобрений , включающий резинокольцевой метатель с прижимным роликом, центробежный вентил тор с воздушной заслонкой, кривойшпношатунный механизм, соединенный с прижимным роликом и заслонкой {2}.A mineral fertilizer spreader is known, which includes a rubber-ring thrower with a pressure roller, a centrifugal fan with an air damper, a curved power steering mechanism connected to the pressure roller and the {2} valve.

Недостатками данного разбрасывател йл ютс небольша рабоча ширина разбрасываии удобрений, а также неравномерность их внесени на поверхность почвы.The disadvantages of this spreader are the small working width of the spreading of fertilizers, as well as the unevenness of their application to the soil surface.

Целью изобретени вл етс повьш1ёние ширины и равномерности разбрасьшани .The aim of the invention is to increase the width and uniformity of spread.

Цель достигаетс тем, что разбрасыватель минеральных удобретпт. включаюа ий резииокольцевой метатель с прижимным роликом, центробежный вентил тор с воздушной зарюнкой , кривошипно-шатунный механизм, соединенный с прижимным роликом и заслонкой, снабжен дополнительным прижимным роликом , который жестко св зан с основным и смещен относительно jero на угол - а, где а - амплитуда колебани роликов, а центробежный вентил тор размещен над резинокольцевым метателем и снабжен воздуховодом с двум противоположно направленными насадками, причем воздушна заслонка расположена перед насадками.The goal is achieved by the mineral spreader. including a rubber ring thrower with a pressure roller, a centrifugal fan with an air gap, a crank mechanism, connected to the pressure roller and the flap, is equipped with an additional pressure roller, which is rigidly connected to the main roller and is offset from jero by angle — a, where is the amplitude of the oscillations of the rollers, and the centrifugal fan is placed above the rubber-ring thrower and provided with an air duct with two oppositely directed nozzles, with an air damper located in front of the nozzles.

На фиг. I изображен разбрасыватель минеральных удобрений, вид.сзади; на фиг. 2 то же, вид сбоку; на фиг. 3 - рабочий орган разбрасьТвател , вид аксонометрии.FIG. I shows the fertilizer spreader, rear view; in fig. 2 the same, side view; in fig. 3 - scatter body, axonometric view.

Claims

The spreader consists of a frame 1, a body 2 with a conveyor 3 and a metering device 4, an auger 5 with right- and left-handed winding enclosed in a casing 6, a disk 7 with a rubber ring 8, with which the upper 9 and 10 mm interacts. videos. The last 39 are mounted on roller holders 11. Centrifugal fan 12 is supplied with air line 13 with air damper installed inside it 14 At the end of the duct there are oppositely directed nozzles 15 and 16, Levers 18 and 19 are mounted on shaft of bevel gearbox 17 and connected 21 with air damper lever 22 and roller holders. The spreader works as follows. When the tractor's PTO shaft rotates, the fertilizer from the body 2 by the conveyor .3 is fed through the metering device 4 into the casing b, from where the screws 5 are fed to the rubber ring 8. By rotating the ring 8, the fertilizers are accelerated and are thrown to the right when running onto the roller 10 and on roller 9 -. left relative to the axis of the passage of the unit. The rollers 9 and 10 are offset relative to each other by an angle of L-a, where a is the amplitude of the oscillations of the rollers. This ensures the symmetry of the spreading of fertilizers with respect to the production axis of the unit. A centrifugal fan 12 generates an air flow that passes the duct 13 and nozzles 15 and 16 is directed in the direction of fertilizer throwing. The air damper 14 is blocked with rollers 9 and 10 They are driven into oscillatory motion from the bevel gear 17 by means of levers 18 and 19 and 10 and 20. When the rollers move down, the range of the fertilizer decreases to the right and increases to the left. Simultaneously the flap 14 turns to the right by reducing the air flow in the nozzle 15 and increasing in the nozzle 16. When the rollers move upwards, on the contrary, the fertilizer throwing distance and the air flow rate in the nozzle 16 decrease and increases in the nozzle 15. The use of the invention allows It increases the spreading width of fertilizers and their uniformity. A mineral fertilizer spreader comprising a rubber ring thrower with a pressure roller, a centrifugal fan with an air damper, a crank-connecting rod mechanism connected to a pressure roller and a damper, characterized in that, in order to increase the width and uniformity of spreading, it is equipped with an additional roller, which is equipped with an air damper, in order to increase the width and uniform distribution of the roller and the damper, in addition to the width and uniformity of the spreading roller a roller which is rigidly connected with the main one and is offset from it. at an angle JT - a, where a is the amplitude of oscillation of the rollers, and a centrifugal fan is placed above the rubber ring thrower and provided with an air duct with two oppositely directed nozzles, with an air damper located in front of the nozzles.
