MACHINE FOR LIQUID FERTILIZER INTRODUCTION TO SOIL

one

The invention relates to agriculture and can be used in machines for applying liquid fertilizers.

Similar machines are known, including the wheel with the needles fixed on its rim at an angle to the spokes of the wheel. But such machines form large slots in the soil, which spoil the vegetation cover and lead to the loss of fertilizers.

A distinctive feature of the proposed machine is that the areas of the wheel rim between adjacent spokes are made along arcs of circumference, the radius of which is less than the radius of the wheel, and the needles are hinged at the intersection points of the areas of the rim. This makes it possible to reduce the size of w, firs, formed by needles in the soil.

FIG. 1 shows the proposed machine, side view; in fig. 2 - the same view in the plape; in fig. 3 - injector at the time of entry into the soil.

On a wheeled tractor, on both sides there are two tanks / for fertilizer, connected to one another by pipe 2 and composed, communicating vessels. On the rear axle of the tractor is a pump 3, working from the PTO. Fertilizer enters it through hose 4 from tanks 1. A high pressure cavity of the pump with hose 5 is connected to a hollow shaft 6, which at both ends rests on the U-shaped frame 7 of the machine. A hole 8 is made on the shaft 6, and a distributor 9 is mounted on it, having outlets corresponding to the number of injectors on each wheel 5. Each tee 10 feeds three corresponding injectors located on three different wheels through hoses L directly.

The rim of the wheel 12 is formed by circular arcs at the intersection points of which, i.e. at the points of the smallest wheel diameter, by the hinges 13 of the sprayers 14 connected to the rim by the return spring 15 and rested in the stop 16. The machine works in the following way.

During operation, the tractor hydraulic distributor is in the "floating" position. Under the force of its own weight, the injector goes into the soil, when the maximum depth of the distributor is reached

9 coincides with the hole 8 of the hollow shaft 6, and when fertilized through triplex 10, the hoses go to three in-line engines on different wheels of the injector n and are being pushed into the soil. Thanks to the convex shape of the wheel

The injector enters the soil with a trajectory that differs little from a straight line, provided that the horizontal component of the force acting on the injector is always directed against the direction of movement of the tractor, i.e. the injector is always

stop 16 and works like a hard finger. Reaching the maximum depth and injection of fertilizer, the injector begins to rise, then its reaction force with the soil changes its direction, overcomes the compressive force of the return spring 15, and the injector, swinging around the ni- rider 13, freely comes out of the soil, but the return spring leads it into initial position.

Subject of the invention A machine for applying liquid fertilizers to a night, including a wheel with needles mounted on its rim at an angle to the spokes of a wheel, characterized in that, in order to reduce the size of w, spruce formed by needles at night, the rim sections between adjacent Siians are made along the arcs of a circle, the radius of which is smaller than the radius of the wheel, and the needles are hinged at the points of the non-crescent rim sections.
