Granulate spreader, especially for fertilizers

Technical field

The invention relates to a granulate spreader, in particular for fertilizer, consisting of a hopper mounted on a mobile frame under which a rotating spreading member is located.

BACKGROUND OF THE INVENTION

Known spreaders of fertilizer or spreading materials are located on the back of a special car or are agricultural machines or adapters towed or carried by a tractor or small tractor. They consist of a bunker or hopper and a feeding device that transports the fertilizer or spreading material to the spreading device. The spreading element is either a propeller rotating on the spreading plate or a spreading disc with a substantially vertical axis. The spreading elements and the feed device are driven by a cardan shaft from the vehicle engine. The disadvantages of the known spreaders are the relatively high demands on their production and the resulting high acquisition costs.

The aim of the technical solution is to create a simple spreader without its own or supplied motor drive, intended for pushing by a pedestrian or towing a small tractor.

The essence of the technical solution

This object is achieved by a granulate spreader, in particular for fertilizer, consisting of a hopper mounted on a mobile frame beneath which a rotating spreading member is located, characterized in that on the axle-bearing frame a substantially vertical shaft is supported above the axle axis. the axle is connected to the shaft by a gear formed by a ring gear and a pinion. This design allows reliable torque transmission from the castors to the spreading element, with the entire system easily accessible.

Preferably, the upper end of the shaft extends into the hopper and a separating member is mounted thereon. This ensures the loosening of the granulate in the lower part of the hopper above the outlet openings.

Underneath the hopper bottom there is a diaphragm rotatable around the shaft axis, the bottom and the diaphragm being provided with holes coaxial in the aperture position open. The aperture is advantageously connected by a bowden cable to a control lever located on the drawbar. The operator can thus regulate the second amount of granulate to be spread.

In order to guide the spreading material, the spreading disc is partially surrounded by a deflecting collar, the lateral part of which is preferably mounted in the travel direction, so that the operator can adjust the spreading angle.

At the top of the hopper there is a removable horizontal sieve used to bring material into the hopper itself with a certain maximum granule diameter.

The plate wheel is provided with holes spaced at regular intervals on a circle in the region of its periphery, and the pinion is provided with pins engaging the holes in the wheel.

The spreader drawbar is fitted with a height-adjustable backrest enabling the spreader to be parked in the vertical position. The drawbar preferably consists of at least two detachably connected parts, which makes it possible to attach to the spreader either a hand push handle or a drawbar for a small tractor.

Figures in the drawing

The technical solution will be further elucidated by means of the drawing, in which Fig. 1 represents a preferred embodiment of the spreader in side view;

in front view, in both cases in partial section.

Example of technical solution

On the frame 1 mounted on the axle 2 a hopper 3 is provided with a removable horizontal sieve 4 in its upper part. On the frame 1 is further mounted a vertical shaft 5 provided with a pinion 6 at its lower end and its upper end carrying a separating member.

7, extending into the hopper 3. A spreading disc 8 is provided on the shaft 5 in its central part, provided with ribs 9 on the upper side.

A deflection collar 10 is partly formed around the spreading disc 8. The deflection collar 10 has a side portion 11 in the form of a guide rail displaceable in the travel direction. The pinion 6 engages with its pins 12 into the holes 13 provided at regular intervals in a concentric circle on the circumference of the ring gear 14 fixed on the axle axis 15

2. Below the bottom 16 of the hopper 3, in which the outlet openings are provided, there is a disc orifice rotatably mounted about the shaft 5. The orifice is also provided with apertures that are coaxial with the holes in the bottom 16 of the hopper 3 when the orifice is open.

The diaphragm is connected to the control lever mounted on the drawbar 17. The spreader is provided with a drawbar 17 which is divided into two detachably connected parts and which carries a height adjustable support 18.

A granulate is poured ^{onto the} sieve 4 through the upper opening in the hopper 2, which, after stitching, passes through the hopper 2 · P ° starting, provided that the orifice plate is in the open position.

8, which imparts centrifugal acceleration to the granules. The granules fly off radially, with the collar 10 preventing their exit in an undesired direction. The side portion 11 of the collar 10 is adjustable and allows the operator to define the scattering angle of the granulate. The vertical shaft 5, together with the spreading disc 8, is driven from the traveling wheels of the axle 2 or from its axis 15 via the ring gear 14 and the pinion 6. The height adjustable support 18 serves the operator to park the spreader vertically, eg when filling the hopper 2.
