Изобретение относитс к области сельхозмашиностроени , а именно к машинам дл внесени удобрений.The invention relates to the field of agricultural machinery, namely to machines for fertilizing.

Известен разбрасыватель удобрений, включающий емкость со шнеком, выгрузной конец которого размещен в патрубке с отверстием пр моугольной формы, и лопастнвй метатель в виде диска с закрепленными на нем лопаст ми I.A fertilizer spreader is known, which includes a container with a screw, the discharge end of which is placed in a branch pipe with a rectangular hole, and a blade thrower in the form of a disc with blades I fixed on it.

Однако эти разбрасыватели не обеспечивают необходимую равномерность распределени различных видов удобрений по поверхности пол .However, these spreaders do not provide the necessary uniformity of distribution of various types of fertilizers over the floor surface.

Целью изобретени вл етс повышение равномерного распределени по поверхности пол различных видов удобрений.The aim of the invention is to increase the uniform distribution of various types of fertilizers over the surface of the field.

Это достигаетс тей, что патрубок шнека установлен неподвижным и снабжен поворотным кожухом, на боковой поверхности которого выполнено отверстие в форме пр моугольной трапеции, причем лопасти на диске метател закреплены с двух сторон, п()и этом количество лопастей по разньге стороны диска различно.It is achieved that the screw nozzle is fixed and equipped with a rotary casing, on the side surface of which a hole is made in the shape of a rectangular trapezium, with the blades on the thrower's disk fixed on both sides, n () and the number of blades on the disc side of the disk is different.

На фиг. 1 изображен разбрасыватель удобрений, вид сбоку, на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows a fertilizer spreader, side view, FIG. 2 shows section A-A in FIG. one.

Разбрасыватель удобрений включает емкость 1, шнек 2, выгрузной конец которогоFertilizer spreader includes capacity 1, screw 2, the discharge end of which

имеет неподвижный патрубок 3, и поворотный кожух 4 с отверстием в форме пр моугольной трапеции, метатель удобрений 5 в виде диска 6, на котором закреплены с двух его сторон лопасти 7, при этом количество лопастей по разные стороны диска различно . Шнек 2 имеет привод 8, а поворотный кожух 4 - зубчатый венец, который входит в зацепление с рейкой 9, св занной со штоком гидроцилиндра 10.It has a fixed nozzle 3, and a rotary casing 4 with a hole in the shape of a rectangular trapezium, a fertilizer thrower 5 in the form of a disk 6, on which blades 7 are fixed on both sides of it, while the number of blades on different sides of the disk is different. The screw 2 has an actuator 8, and the swiveling casing 4 has a toothed crown, which engages with the rack 9, which is connected with the rod of the hydraulic cylinder 10.

Устройство работает следующим образом .The device works as follows.

Claims

When liquid and viscous fertilizers are applied to screw 2 by means of drive 8, the rotational speed at which it acts as a pump is communicated, hydraulic cylinder 10 moves rail 9 which rotates the barrel 4 relative to the nozzle, thus forming a metering gap of a certain size. In this case, the fertilizers enter the metering slit over its entire cross section and are evenly distributed along the width of the scavenger. If the blades are equal in width 7, the same amount of fertilizer comes to both sides of the disk, and so Kak the number of blades on each side of the disk is different, then the weight portions of fertilizer coming into one blade on different sides of the disk will be different and will be spread out to a different distance. This will lead to an improvement in the uniformity of fertilizer distribution over the surface of the field. When applying bulk fertilizers, the cover 4 is rotated by 180 °, while the metering slot takes the shape of a rectangular trapezium. The speed of rotation of the screw through the actuator 8 is set depending on the desired application rate. Fertilizers flow to the thrower, rolling over the inclined edge of the casing opening H, and are evenly distributed across the width of the blades 7, and then distributed by the thrower, as in the first case, with increased uniformity on the surface of the field. The invention includes a fertilizer spreader comprising a container with a jaw, the discharge end of which is housed in a nozzle with a rectangular hole, and a blade thrower in the form of a disk with blades fixed on it, in order to increase the uniform distribution of different types of fertilizers, the nozzle of the screw is fixed and equipped with a rotary casing, on the side surface of which a hole is made in the shape of a rectangular traction, and the blades on the thrower's disc are fixed with two sides, with the number of blades on different sides of the disk.
