SU26483A1 - Potato harvester with feed transformer and haulm topper - Google Patents

Description

 The invention relates to potato diggers equipped with a digging blade with a device for pulling out the tops of the tops and with a feeding scraper conveyor carrying a feathered combs, consisting of two tooth systems, of which longer and more resiliently fixed for one side are double combs and shorter ., located in front of him, pivotally suspended from the conveyor chain. In the proposed machine, in order to more intensively loosen the tubers and the soil when they hit the trough with the trellised bottom, a transverse set is placed under the latter (sa, the slats of which serve as stops for the long teeth of the comb; During forward movements of the machine, the topper is caught by the tops of the topper wheel, clamped between its rim and chain, it is pulled out and carried to the side.

Nor is the drawing of FIG. 1 and 2113 are shown in two projections from a side view of a potato harvesting machine with a feeding conveyor and a haulm topper; FIG. 3 and 4 - view in two projections of a double comb; FIG. 5 shows the transfer of movement to a haul-off device.

during the forward movement of the said machine, the plowshare 29 digs up the potatoes, which go along the outlets 3 and 3 to the large topper-pulling wheel 4, which, rotating, grasps the tops with its wire pins, clamps it between its rim and endless belt 36, pulls the tops and throws her to the right of the car. The endless belt 36 of the haulm toggle attachment interlocks with the horizontal teeth 25, 26 mounted on vertical rods 33, 34 mounted on the frame 40, on which also the rod 32 is mounted, carrying a horizontal wheel 4. The belt 36 is put on a rubber tire so that it does not cut the rim of the wheel 4 and the belt 36 while cutting the last rim. In order to avoid the possibility of the endless belt 36 slipping off the wheel rim, the last 4 hairpins of the latter, which are used for closing the tops, are set at distances Equal to the length of two links tape 36. The size and installing large wheel 4 and two small zubchatok 25 and 26 must meet the following requirements; clamping the leaf between the wheel

4 and the endless belt 36 must begin over the middle of the plowshare 29 and end above the outer edge of the right, timber rigidly fixed to the walls of the longitudinal grid 31.

The device for pulling out the tops is driven from the bottom gear mounted on the axis 6, on the right end of which is mounted a bevel gear that engages with the bevel gear 22 (Fig. 5) sitting on the vertical rod 7 mounted on it the upper end of the transmission gear 5, through which the drive chain 35 is thrown to the gear 24, is fitted on the rod 32 (Figures 1 and 2).

. After pulling out the tops of the tops, the tubers along with the soil fall from the plowshare 29 on the curved part of the chute 30 and are loosened, which is facilitated by double combs 27, which easily hit the bed and separate the tubers from the soil. The combs 27 of the conveyor 37 are provided with teeth of the two systems; With long wire teeth B (Figs. 3 and 4), fixed nuts M to the shoe D double comb 27, and shorter teeth A of the tray shape, pivotally connected to the shoe D g, banks 27. On the wallpaper ends of the shoe D comb 27 is fixed on one plate B, the length of one link of the conveyor chain 37- BepjjHHM with the end of the plate B- is attached to the chain L of the conveyor 37 to the lower end of the plate, the plank H is attached, its other end connected to the chain L (Fig. 3 and 4). That is. fastening combs 27 should provide greater stability during operation. The number of wire B and gutter A teeth of each double comb 27 should correspond to the number of gaps between bars 3 (Fig. 3 and 4) of the longitudinal lattice so that over each gap there is one wire B and one bast A tooth of the comb connected. between each clamp e (Fig. 3 and 4).

Under the longitudinal grid 31, which forms the bottom of the chute 30, there is a reinforced transverse mesh with toothed slats and (Fig. 3 11 4) serving as stops for the wire teeth of B, which, like longer ones, pass between the slats of s forming the longitudinal grille of the chute 30 hooked onto the straps and the transverse mesh, deflected further. transporter, jump off them and, hitting the earth layer, contribute to the intensive loosening of soil lumps and 60l to perfect cleaning of tubers from the ground. The latter, carried away by the teeth of the ridges 27, are directed to a small trap suspended from the ring 16 with a tail wiping out of the soil through the cage bottom of the chute 30.

The conveyor 37 is set in motion from the axis of the traveling wheels by means of two pairs of transfer belts thrown over the teeth 19 fastened to the axis of the wheels and the teeth IS mounted on the shaft carrying the teeth 20 connected with the feed belt 37 to the gears 21. Sleeves these gear teeth are made so that when moving them to the side, you can turn off the conveyor 37, and when connected, turn on the latter. The conveyor is turned on and off by a lever 8 located behind the seat 15, and one pair of levers 9. The invention.

Claims (2)

1.Potato harvesting machine with feed1, / conveyor and fixture. for pulling out the tops, characterized in that in order to loosen the earth layer under the longitudinal grid forming the bottom of the chute 30, the transverse mesh with the slats is reinforced, and serving as stops to spring the teeth of the double comb 27 pivotally linked to the conveyor chain and connected collar e and missed between the bars h, forming the longitudinal lattice of the chute 30. 2. In a machine according to claim 1, use of a device for pulling out a tops of water, characterized in that on the frame 40 there are installed vertical rods 33, 34, misaligned teeth 26 and 25, coupled with endless tape, and a rod 32 bearing a roller 4, intended for pressing rim, to a ribbed tape from the left.
