Description

The peculiarity of the proposed beet harvesting machine, which has a topping machine and is equipped with a conveyor, is that it uses rotating rollers with a helical surface located between the digging organ and the topping machine and intended to expose the beets in a row, for the convenience of grabbing this beet topping apparatus. FIG. the drawing shows a side beet harvester; in fig. 2 is a view of the topping deck; in fig. 3-view of the transmission wheel 18 and the transporter 16 on top.

The frame 26 is pivotally suspended to the main frame of the 25th machine, resting on a four-wheel drive, and the working parts of the machine are attached to this frame. In the front part there are coulters 5 of which are first-paired, they pass on both sides a row of beets and serve as a loosening ridge from the sides, while the coulter 4 is intended to heave up a row of beets from below. Behind the coulters 4, there are pairwise rotating rollers 5 opposite to each other with a screw surface, the purpose of which is to expose the undermining, but beetroot sitting in the ground, for the convenience of gripping it with a top-lifting apparatus following the rollers. The rockelling apparatus (Fig. 1 and 2) is made in the form of a wheel b with radial grippers, which have the form of paired lips 7, equipped with rollers / 2. When the wheel 6 is rotated by the chain gear 9, the rollers roll along the guides 8 in order to open the clamps at the moments when the beets are seized and also at the moments of its release. The lips are closed under the action of springs 28. A pulling machine removed the beet from the soil and the wheel 18 mounted above it, the grips of which clamp the beets so that its head with leaves is located towards the periphery and protrudes from the grips. The wheel grippers 78 are also made in the form of pair lips J7 and are equipped, for the purpose of their closing, with springs 30, and with the aim of opening them with CG rollers interacting with fixed guides 33 (Figs. 1 and 3). The wheel 78 is driven by the JO chain drive from the traveling wheel // machine. The lifting gear and the wheel J8 are mounted on the rack 32 of the frame 26 and, independently of the latter, can be mounted vertically using the set screw J9. Clamped in the clamps T7 of the wheel 78, the beets are transported to the knife 20, which cuts off the head of the beets with leaves;

a head falls off the grate 24, and the beets are picked up by the paired belt conveyor 16, which moves to the bunker J4. On the way to the bunker, the root of the beet is cut with a circular knife / 5. The bunker / 4 is provided with an automatically opening wall 13 held by the lock 13.

FIG. Figure 1 represents the machine in working condition. When transporting the machine in non-working state or when adjusting the depth of the frame 25, and, consequently, the coulters 5 and - /, the rollers 5 attached to it, the lifting gear 6 and the transmission wheel / are raised up using screw pair 2 with the steering wheel 27. The front kiejieca machines are mounted for rotational movement and serve as driving movements; they are controlled by a lever 7.

The subject matter of the invention.

I 1, A light semi-automatic harvester with a top-lifting device and a conveyor belt, characterized with the use of rotating rollers 5 with a helical surface, located between the digging organ and the top-lifting machine for exposing

In the row of beetroot, for the sake of convenience, and capture it with a pulling device. 2. In the car according to claim 1 application

The transfer wheel IS, which serves to feed the beets to the knife for trimming tops.
