(54) RADICAL FERTILIZER SPREADER

one

The invention relates to agricultural machinery, and more specifically to hand-held fertilizer spreading devices intended for use mainly in areas not accessible to mechanized vehicles.

A knapsack fertilizer spreader is known, which includes a hopper with a nozzle made of elastic material and an L-shaped lever that is hinged on the bunker case and is a fertilizer booster, one end of which is rigidly fixed on the wall of the seeding nozzle and connected to a handle. , and at the other end, located in the bunker, installed the arch-destroyer 1.

A disadvantage of the known knapsack fertilizer spreader is the high dust content in the worker's breathing zone by the volatile fractions of the applied fertilizers due to the fact that the sowing nozzle is constantly ahead of the worker.

Also known knapsack fertilizer spreader, which includes a hopper located in the lower part of the seed

window, a lever for stimulating fertilizer sowing, an arbor destructor associated with it, and a hinged mounted seed tray.

In this satchel fertilizer spreader, the formation of dust in the worker's breathing zone during fertilizer application is excluded, since the replaceable tray is located in the working position behind the worker 2.

The disadvantage of this knapsack fertilizer spreader is the inability to maintain the sowing rate of fertilizers constant throughout the entire time of sowing fertilizers, as well as to regulate the number of sowing fertilizers due to the fact that the sowing rate of fertilizers depends on the amplitude of oscillations reported by the working lever arm to stimulate the sowing of fertilizers. And since the worker gets tired when applying fertilizer, he cannot maintain the amplitude of oscillations of the lever that promoted the sowing of fertilizer during the whole time of fertilizer application. In addition, maintaining a constant amplitude of oscillations of the lever, a driver for planting fertilizers, requires great effort and attention from the worker, which further tires the worker.

The purpose of the invention is to regulate the amount of fertilizers sown and increase the ease of use of the knapsack fertilizer spreader.

This goal is achieved by the fact that, in a known satchel fertilizer spreader, which includes a hopper with a sowing window located in its lower part, an incentive lever for sowing fertilizers, an associated wrecker and a hinged-mounted interchangeable tray, a lever for driving fertilizer sowing is equipped with a limiter for moving it, and a removable tray with a hinged-mounted replaceable tray. on the side wall of the bunker, while the arch destructor is hinged inside the bunker above its sowing window and is made in the form of an impeller, and the bunker is made in the form of a truncated iramids, the larger base of which goes into the cylindrical part and faces down.

FIG. 1 shows a knapsack fertilizer spreader in the working position, side view in section; in fig. 2 - the same, in the position prepared for transportation, front view; in fig. 3 - the same, side view; in fig. 4 - interchangeable tray, top view; in fig. 5 - the same, side view; in fig. 6 is one of the constructive embodiments of the interchangeable tray, top view.

The knapsack fertilizer spreader contains a hopper 1 with a sowing window 2 located in its lower part, a driver for driving 3 sowing of fertilizers, an associated wrecker 4 and a pivotally mounted replaceable chute 5. The driving lever 3 for sowing fertilizers is equipped with a stopper 6 for moving it, which is mounted on the side the wall of the bunker 1, while the blaster 4 is hinged inside the bunker 1 above its seeding window 2 and is made in the form of an impeller, and the bunker 1 is made in the form of a truncated pyramid, the larger base of which is It goes over into a cylindrical portion and facing downward. The bunker -1 of the spreader fertilizer spreader is attached to the back of the worker with the help of lm 7 and cross member 8. A soft pad 9 is fixed on the front wall of the bunker 1 for more convenient fixation of the bunker on the back of the worker. The bunker 1 is equipped with a flap 10. The impeller of the arching device 4 has several flat blades that are installed at the same distance from each other and overlap the seeding window 2 i in one of the extreme positions of the lever-inducer 3 for seeding of fertilizers defined by the limiter 6. The impeller of the deflector 4 performs simultaneously with the destruction of the set of fertilizers in the bunker 1 the role of the dispenser. In order to ensure adjustment of the fertilizer seeding rate, depending on the angle of rotation of the impeller of the camshaft 4 and the amplitude of oscillations of the lever-driver 3 of the fertilizer seeding, the limiter 6 is set to

rearrangement of it on the side wall of the bunker 1. The lever-driver of 3 sowing of fertilizers is brought forward to the zone of the right hand of the worker. To ensure continuous sowing of fertilizers under the seed window 2 on

the hopper 1 is hinged to replaceable tray 5 with a flat base (Fig. 6), and, if it is necessary to plant fertilizers, a removable tray 5 with a longitudinal partition is installed in the line on the bunker 1 (Fig. 4). To fix the removable tray 5

in the transport and operating positions serves as a lever 11.

Works knapsack fertilizer spreader as follows.

The bunker 1 is filled with fertilizers to be spread and is covered with a lid 10. At the same time, the interchangeable tray 5 is installed by the lever 11 in the Kenya transport field. With the aid of the bow 7 and the cross bar 8, the hopper 1 is fixed on the back of the worker. At the place of fertilizer spreading, the worker sets the required seeding rate of fertilizers by swapping the limiter 6 on the side wall of the bunker 1 to the appropriate position and using the lever 11 fixes the replaceable tray 5 in the working position, in which it is located behind the worker. Then the worker, having taken the lever-stimulator of 3 sowing of fertilizers into his right hand, begins to move the driving lever of 3 sowing of fertilizers to the extreme upper and lower positions to

5 stops in the stopper 6. As a result, the impeller of the bomber 4 starts to swing, the sowing window 2 opens for a certain amount, through which fertilizers begin to pour out onto the removable tray 5. The replaceable fertilizer tray 5 is evenly sown on the soil surface behind the worker without creating dust in the breathing zone of the worker. Depending on the required fertilization scheme, an appropriate

5 interchangeable tray 5.

The use of the proposed knapsack fertilizer spreader ensures a constant, specified seeding rate of fertilizers during the entire time of fertilizer application without the cost of additional energy for workers, which in turn allows for efficient use of it in areas not accessible to mechanized equipment.
