Rake reaching through rust.

In the accompanying drawing, α represents a frame which is mounted on the axis b with the bicycles b _l . A countershaft c with a spur drive c is mounted on this frame α , which engages in a larger spur gear b ₂ on the bicycle axle; This back gear drives a second shaft d with crank disks d by means of a chain on the disks C ₂ and Cl _{1. 2} , also mounted on the frame α ; the bearings can be adjusted lengthways by means of screws d _s to tension the chain. The crank webs d ₂ move through lever e and handlebar e _Y and e _{2 is} a cleaning and transport rake ff _x in the openings of the fixed grate g _z behind the plow bodies g and down as dotted in Fig. Ι indicated to cabbage and potato to loosen up and move on; the earth falls for the most part through the Rostg · ,.

A second lever mechanism follows this first and drives the sieve h (Fig. 6 and 7, e ₂ kk ₁ Ar ₂ ), which hangs laterally inclined in the brackets H ₁ h ₂ h _B and the potatoes, rolling to this side, fall to the ground in a row, while the herb passes the long rods of the sieve and falls off beside the potatoes (Fig. 2). According to the accompanying drawing, the sieve and the transport rake are arranged to work together so that the sieve can take up the parts supplied by the rake well. The sieve pushes against a pin with a spring in the bracket h ₂ , Fig. 1, in order to better remove the soil particles from the potatoes by the shock.

The plow body g slides on a wide base t and is attached to the frame rq; This frame is firmly connected to the tie rod Ip (Fig. ι and 2), which is set high and low in the cross piece η by screw TM ₁ and in the end piece ο by screw O ₁ to allow the plow tip to penetrate more or less into the earth permit. By raising and lowering the draw hook a ₂ over the frame a , the aim is to load the bicycles more or less when pulling in order to prevent them from sliding; at the same time, the tow hook a ₂ can be adjusted laterally by this device.

For better transport of the machine, the same can be achieved by removing the bolt I ₁ and stripping the lever e from the crank discs d. ₂ divisible. Ratchet wheels with pawls in the hubs of the bicycles mean that the plow only works when moving forward, but when turning or walking backwards the whole apparatus stops working.

The mode of operation of the transport and cleaning apparatus is as follows:

Due to the forward movement of the machine, the clod picked up by the coulter g arrives at the fixed grate g _x , where it is removed from the shaking and conveying rake f, which with

works at great speed, receives a powerful blow when it swings up; this dissolves the mass and sets it in a hopping motion. The greater part of the earth falls off by the vibration, the tubers roll, etc, thrown from which an inclined plane forming conveyor grate, the shaking grate h; this is moved by the handlebar e ₂ , FIGS. 6 and 7, of the rake / by means of the lever k It _{1 in the} opposite direction against this, so that the tubers are well caught by the shaking grate h; they are here cleaned of the earth and sorted through the different gaps and unequal lengths of the grate bars, while at the same time the herb passes over the long bars after the potatoes have fallen through.

Claims (1)

Patent claim: . A potato harvester with a coulter and a grate attached to it, characterized by a rake f, the prongs f _x of which are bent steeply upwards from the crossbeam below the grate, then diagonally downwards to the rear, thereby forming a grate which, with the help of cranks <L and hinged rods ee, is moved in an ellipse-like curve, for the purpose of moving the potatoes backwards on the grid and cleaning them of soil in the process. For this purpose ι sheet of drawings.
