SU32812A1 - Machine for harvesting root crops, potatoes, etc. - Google Patents

Description

Machines for harvesting root crops, potatoes, etc., are known using keyboard conveyors. In the proposed machine, the conveyor is composed of fixed slats, between which there are sliding slats driven by a crankshaft.

In FIG. 1 is a side view of the machine; FIG. 2 shows the arrangement of movable and fixed conveyor plates.

In the front of the machine frame, a device for haulm topping is installed, consisting of an inclined frame 32, on which guide shoes 33 are fixed, feeding the dead leaf and equipped with rods 22, which serve to protect the potato tubers from being pulled out by the conveyors 2. In front of the conveyor 2 there are disks 5, designed to separate the matched tops of the two adjacent rows. Conveyor 2 serves to grab the tops, pull it out of the soil and transport it to the trough 14, from where twa

lift 28 is fed to box 10. As the tops in the box accumulate, they are thrown into a heap on the ground or in a row by a walking cart.

Digging up root or tubers is done by the ploughshare 29 mounted on the frame of the conveyor 6. The latter serves to feed the mass excavated by the plowshare to the keyboard conveyor 12, which is used to clean the root crops of tuber crops from the ground, stones, weed tops, etc. Keyboard 12 composed of a system of fixed strips / 5, representing a lattice. Between the fixed bars 75, movable bars 30, which are rotated by the crankshaft 27, are installed. The fixed bars 15 and movable bars 30 are suspended from the end of the machine to the frame by spring 9. Both bars systems are zigzagged, and the fixed bars 75 are shorter and their ends are located above. the elevator 36, and the movable slats are longer and the ends of them are located behind the elevator 36 above the soil surface.

Dug-up plowshares of 29- or “lubneplodies” arrive at the conveyor 6, which moves them along with the ground, “oor, etc., to the keyboard conveyor 12, where the root or tuber crops are cleared from the ground and various rubbish. Due to the presence of movable strips .5 installed in a reversal with fixed strips 75, the mass entering the conveyor is vigorously ground; earth and fine litter fall through the grids of movable and fixed planks, potatoes or other harvested roots and tubers are moved to the rear of the fixed slats, making a zigzag trajectory, and fall through the elevator 36, with a large litter moving moving fingers to the back of them and dumped behind the car to the ground. Cleared from the earth and litter - an elevator 36 root-ilr tuber crops

dumped into the bunker mounted on the frame of the machine, from where they are taken by the unloading lift into the wagon.

The subject matter of the invention.

Claims (3)

1. A machine for harvesting root crops, potatoes, etc. with a keyboard conveyor, characterized in that the conveyor 12 is composed of fixed bars 15, between which movable strips 30 are placed, driven by a crankshaft. 2. Machine according to claim 1, characterized in that the strips / 5 and 30 of the conveyor are zigzag-shaped. 3.
