Description

A machine for planting potatoes using a rotating finger rotor in a feeding bucket of a planting machine with a scoop wheel, as well as using movable bottom parts in a seed hopper of a machine for nesting potatoes with a scoop wheel.

A distinctive feature of the proposed machine is that the seed bunker used in it is equipped with reducible ones. And the oscillating movement is with the bottom parts, and the rotating rotor has multi-curved fingers that keep the tubers through the bars between the nutrient bucket.

FIG. 1 shows a painting, side view; in fig. 2 is a plan view.

Two running wheels 2, frame 3 with seed bunkers 4 mounted on it, equipped with movable bottom parts 5. nutritious buckets 6, having rotating rotors 7 with multipronged bent fingers and augers 8, landing devices 9 and tukovyvayuyup1 by their JO machines.

Landing vehicles are pairwise rigidly mounted on two shafts //, Binippei whose ends are connected by a clutch 2.

A gearbox 13, having a cardanG (shaft M, an automatic machine 15 with a gearbox 16 to the cardan shaft 17, and an assembly of traps 18, is also attached to the frame.

In addition, openers are secured to the beam of the frame by means of hinged chetyrehtverenpik J9. Each opener has a support wheel 22, a receiving funnel 23 and a four-blade rotor, 24. The rotors of all openers are connected by means of cylindrical shchestren 25 through a pair The bevel gears, located in the box 27, are connected with the cardan shaft 17 of the machine gun. To the coulters fasten the sealing discs 28 and the drills 29, having an additional suspension 30 to the frame of the machine.

No. 125426,

The shaft of the gearbox with the shaft of the machine and the shaft of the machine with the shaft of the landing Ashparatav respectively are connected by chain transmissions. With the shaft they landed 1, their devices, in turn, are connected in chain-chain finger rotors, augers and tukovysevuyuschie devices.

To attach the machine to the tractor on the frame beam and on the coulter attachment brackets 20, there are corresponding holes and fingers. A mechanism 31 is provided for the operation of rotating working bodies.

In order to change the planting density, interchangeable (detachable) sprockets are installed in the machine, which, if necessary, are mounted on the shaft of the machine.

When the machine is moving across the field, the potato tubers from the bunker 4 are transplanted by the planting devices 9 and granulated fertilizers from the machines 10 through the tuples through the receiving hopper 23 are continuously fed into the coulter 21, to the compartments of the four-blade rotors 24 formed by two adjacent blades.

At intervals of the machine’s path, equal to that of the interglacial, the next stop of the measuring wire deflects the plug of the catcher 18, which switches on the machine through drafts, levers and rollers. At the same time, through the driveshaft 17, the bevel gears of the box 27, the articulated shaft 26 and the spur gears 25, the rotor of the coulter rotates 90, after which the automatic switch is turned off. When the next wire stops go through the knotter fork, the working cycles are repeated, whereby the tubers along with the fertilizers are planted on the bottom of the furrow made by the coulter.

The furrows are closed by discalgia 28 or discs and drills 29.

To ensure uniform feeding of the tubers to the planting apparatus and eliminate gaps in their work, the vibrating movement of the bottom parts 5 (agitators) are installed in the bottom of the seed bunker 4, and rotating rotors with multi-fold curved fingers and feed screws are mounted in the feeding bucket CLS to the landing devices, driven from the tractor's power take-off shaft through chains, sprockets and other transmission details.

To eliminate tuber formation in the seed bunker, the movable bottom parts 5 of its inclined bottom return to the lower position not from the weight of the tubers perceived by them, but from the action of springs, which creates conditions for slump (seed) on the bottom of the bunker and for intensive flow into the nutrient bucket to rotating finger rotors.

To eliminate the possibility of damage or seizure of the tubers between the bottom of the nourishing bucket 6 and the fingers of the rotor 7, the latter are bent along the radius in the direction opposite to their rotation. The rotors 7 are installed in the slots x of the bottom of the nutrient bucket 6, the jumpers of which have a free end for ejection of impurities by the fingers of the rotors.

The movable bottom parts 5 of the bottom of the seed hopper 4 and the finger rotors 7 are positioned so that the movement of the tubers takes place both in the longitudinal direction - towards the end of the nutrient bucket 6, and in the transverse direction - towards the landing apparatus 9.

The dimensions of the finger rotor and the screw, the size of the exit of the rotor's fingers into the inter-bar lumens of the nutrient scoop and the revolutions of the screw and the rotor are chosen so that the nutrient ladle does not create a shortage or excess of tubers for feeding the planting apparatus. with a certain opening of the seed hopper flap.

Subject invention

A machine for planting potatoes and simultaneously applying fertilizer to the soil using a seed hopper with a rotating rotor located in a nutrient dipper and with a planting device, which, in order to improve the uniformity of tuber supply to the planting unit, the seed bunker is equipped with an oscillating movement of the bottom parts, and the rotating rotor has multi-curved fingers, lifting the tuft through the inter-bar lumens of the nourishing scoop.
