Description

The invention relates to cabbage harvesting machines using paired endless chains for capturing stumps and disk knives, cutting the fork from the stalk. In the proposed cabbage harvester, in order to clean the fork from unwelded leaves, vertical knives are used, which are under the influence of springs, and, to prevent knives from forks from being damaged, limiters are used. To protect the conveyor chains from bending, they are provided with rollers mounted in guides.

In FIG. 1 is a side view of a cabbage harvesting machine with a partial cut; Fig, 2, the same, a view in the plan; FIG. 3-side view of the cutting unit with a partial cut; FIG. 4- view of the cutting apparatus in the plan; Fig, 5 is the same, rear view; Fig, 6 is a diagram of the operation of vertical knives and stops.

The cabbage harvesting machine on offer is chetyrehko381

a forest carriage with two cabbages mounted on it for cleaning two rows of cabbage at the same time; on the slide 7, hinged to it suspended from it in order to adapt the working bodies to the unevenness of the soil. In front of the sled 7 attached to them at an angle to the ground fork 7, the Purpose of these FORKS; pick up cabbage leaves bent to the ground and lift them upward to expose the stalks. The frame 26 is mounted paired gear chains 2 (Fig. 1, 2, 3 and 4). The chains are set at an angle to the soil in accordance with the movement of the machine and are thrown over asterisks 3 and 27, and the anterior asterisks 3 can diverge to the sides in the case of thick stalks. Chains are pressed

to each other, a number of springs 4, and in order to protect the chains from bending, they are provided with rollers 5, which roll as they move along the guides 6. In order to prevent the slide from digging into the ground under the weight of the cabbage lift, the ha 8 is attached to the ground spring //. By turning the handwheel 9 by means of a worm gear 70 (Fig. 1), the spring // is compressed, thereby reducing the pressure of the cabbage lifter on the ground. For the transport position, the spring 7 / is compressed to the full, and by further turning the handwheel 9 t, the goy 8 rises the entire cabbage lift.

When moving the car along the cabbage rows, the front forks / raise the cabbage leaves lowered to the ground, exposing the stump that falls between the chains 2, is caught and transported upwards, due to which the forks are pulled from the ground. The cabbage held onto the stalk by the toothed chains is brought up to the vertical knives / 2 and pulled further. The knives are set at an angle to the line of movement of the fork and are equipped with limiters J3 (Figs 1, 2, 3, 4, and b); in addition, the knives are lifted up all the time by the spring J4 (Fig. 3). Knives, pressed with a sliding fork down, cut the side (not curled) leaves. When the knife, cutting all the loose leaves, reaches the fork, the stops J3, resting against the bare forks, do not allow it to be cut (Fig. 6).

The limiters / 5 move into the tentacles 73, which, along the bottom of the fork, slice the cabbage, bring it to the paired, rotating towards each other, disks / b, which cut the forks from the stalk. At the same time, the toothed disk J8, installed under the conveyor 2, cuts off the root part of the stalk. The forks pressed against the top by the ribbon 77 are dropped into the hopper 24 with a flip bottom. The blade knives 76 are mounted on rollers J9 carrying gears 20, which are driven in rotation from the drive shaft 25 through an appropriate gear. In order to adjust the cutting height of the stalk, the knives J6, together with their rollers 79, can be moved up and down, the slippers in the hub of the bevel gear 20, and both knives are moved to the same height at the same time due to the connecting bar 27.

The tentacle guides 75 are all the time parallel to the circular knives 76 and are from the last distance of the same distance due to the articulated parallelogram ABCD.

When harvesting fresh cabbage, the vertical knives 72 and the circular knives 76 are removed and, therefore, only the root part of the plant is cut.

The front of the machine, in order to adapt it to the terrain, is made swinging and is controlled by the steering wheel 22 through a worm gear 23,

The subject matter of the invention.
