Description

The proposed machine is intended for harvesting corn by tearing off the stalks and folding the ears into a collection box and then cutting the stalks.

In FIG. 1 shows the car on top; FIG. 2 is a transverse vertical section of it; FIG. 3-- vertical longitudinal section of it; FIG. 3S 4 and 5-part device.

The base of the machine is a horizontal frame of the side lanes 7 and 2, the rear 3 and the front curved 4. This frame is mounted on the shaft 5 with the wheels b and 6, the frame 7 is reinforced rack 7, bearing an arc of 8, 9, 10, equipped with bearings 11 v . 12. In these bearings, the shaft 13 can rotate with the mounted cross-pieces 18, to which the pair of curved wings 14 (in the amount of four), which are the main working body of the machine, are articulated. Each wing consists of a horizontal curved bar 7 5 (Fig. 3), vertical

the side wall 16 and the rear wall as well as the vertical wall 17. The shaft / S with wings is rotated in the direction of arrow a (Fig. 3) from the axis 5 of the traveling wheels as follows. A conic gear 19 sits on the shaft 5, which engages with the bevel gear 20, which sits at the bottom of the shaft 23. This shaft carries the gear 27 at the top, which engages the gear 22 on the shaft 13. Between the sides of the arc 8, 9, 10, the braces 24 are reinforced. On these trusses, curved circular double guides 25 are fastened, between which rollers 26 are connected, connected to wings 14. A convex toward the wings, the shape of guides 25 strongly diverging below, then coming closer and again diverging, is such that in each a pair of wings 14 in the lower in the position of divorced, then m square skho dts and, approaching the top position, again diverge; Coming down, the wings pass between a double ramp 27, 28. placed above the collecting box 29.

Mashines E is directed to work so that plants of a certain corn fall between divorced wings / 4. Climbing along the stem, each pair of wings gradually shrinks and, hitting a thickening formed by a spine reinforced in the leaf's spine, it should tear off the cob. Torn cob,. in view of the curved shape of the wings and the presence of the side and rear walls 16 and / 7, it does not fall down on the ground, but is retained on the wings and then, along the slopes 27 and 28, is dropped into the box 29.

In order for the corn stalks to be free from the ears of corn, the machine is equipped with a knife cutting device 30 of a conventional device, placed so that it cuts off the stalks after the cobs are torn off. The movement of the knife band is received from the cylindrical tooth 31, which sits on the shaft 5, which engages the tooth 32, which engages on the auxiliary shaft 33. The shaft 33 also carries a conical gear 34 which engages with the gear 35, which sits on the roller 36. The other end roller 36 carries races (eccentric) 57, with the help of a connecting rod 38 connected to the head of a knife strip. A bar 39 is attached to the side of the knife apparatus, which serves to roll off cut-cut stems to one side.

Wings 14 can be arranged in no other way (Fig. 4 and 5}. They differ from those described above primarily by the fact that beads 16 are made much higher (which reduces the possibility of falling off the removed cobs to the ground), and the wing itself is made In the wing section 40, holes 1 are drilled through which the spokes 4 / are punched, forming the horizontal plane of the wing. Spokes BTi-i are articulated by connecting rods 42 with roller 43. The bead can be

one way or another, we periodically turn a certain part of the circle into, one and the other side; in one direction it turns, for example, cam: -g:) 1l aezz 44. and in the other direction - spring 45. Being rigidly attached to the rods 42, the roller, when rotated in one direction, makes the spokes 4f go out of the frame 40 , and when rotating in the opposite direction of the spokes, the entrance r is inside the frame. Needle convergence m. A. their entry into the respective frames of neighboring wings occurs at the moment of the capture of the cob, the divergence occurs when the wings approach the collection box. The rollers 26 according to the new version are fixed on the springs, which allows the wings to adapt to the stalks and cobs of different thickness.

The subject matter of the invention.

Claims (2)

1. A corn picker that separates the cob, characterized in that paired bent wings are used to break the cobs, which are provided with sides on the sides and the back side, rotating on a horizontal shaft and using one or another guide on one side of their path pressed against each other. to each other, and on the other retracted from each other, which are wings, grasping the stalk of corn and the passage pressed to it from the bottom up, the cob is intended to be picked off the cob, and then thrown off the cob into the collection box. 2. The form of the machine according to claim I, characterized in that the wings are provided with fingers (spokes) (Fig. 4 and 5j, connected to the shaft S by the moment of grip of the wings by the stem using one or another device that turns and causes the fingers to enter in the wing frame and how to comb the corn. fng.2. // t y / f D JT and i |.   i - i i  t-iHi- |
