Description

In the proposed cabbage harvester, for the purpose of using the stalks to feed livestock, with their separation during harvesting, two knives are used, one of which serves to cut the stalk from the stump and the other to trim the roots from the stalk. The collection of the cabbage of cabbage and forage residues of the stalks is done in separate boxes using two conveyors. A special device is used to separate the lower leaves from the tails and to sort the tails.

In the schematic drawing of FIG. 1 shows the top view of the car; FIG. 2 is a side view of it; FIG. -3-a part of the receiving chains from above; FIG. 4, 4 view in two

the projections of the finger guiding the hocks to the receiving chain; FIG. 5 is a view of knife segments for cutting root parts; Fig. 6 diagram of the device for sorting

Kochnov and to separate the lower leaves from the Kochnov; FIG. 7-section of the knife for trimming the stalk from the sandpaper.

The proposed multi-bottom machine (Figs. 1 and 2) for cabbage harvesting consists of paired fingers J, designed to guide the heads to the paired chains 2 and are made, in the form of a wedge, 379

acute from the front end and strongly thickened towards the rear end (Fig. 4). The outer side of the finger is straight, and the inner, where the patches pass, are made along an arc of a circle with an inclination inward. The fingers are provided with sockets / for installation of sprockets of the conveyor chain 2 (Fig. 1 and 3). The latter is made of a steam room for each row of cabbage and serves to pull the cabbage from the soil and transport it to the cutting devices. The chain consists of individual links B, made in the form of bars, with a cut along the arc of a circle so that the opposite links of two parallel chains form nests for capturing cabbage stalks for the stalks. The conveyor brings the cabbage first to the knife to cut the root part of the stalk, and then to the second knife to cut the stalk from the stalk. conveyor 2. In each group there are three segments (Fig. 5), with the outermost segments being a triangular plate with a rounded

arc of a circle apex; the middle segment — the larger one — is also made in the form of a trapezoid-shaped plate. The knife is driven in a swinging motion by a crank b from the tractor's propeller shaft. The blade bar 4 is installed in a guide box, which is provided with plates 7, representing the second part of the cutting pair. Such a knife arrangement, in the opinion of the holder, should ensure the normal cutting of the root parts from the stalks. The roots cut by the knife fall into the collection box 8, and the head is transported to the second knife, which cuts the stalk off the branch. This knife also consists of a knife bar (Fig. 1 and 7) with riveted to it, against each row of cabbage, of a certain length by saw plates JO. The knife is set in a swinging motion by a crank / 7 from the cardan shaft of the tractor. Cut off the stumps fall onto the conveyor belt / 2 located under the knife and the latter is fed into the bunker 73. At the time of the stump cutting, the head is picked up by the rollers / 5 of the upper conveyor 74 (Fig. 2 and 6) and dragged between the toes of the comb 79, what is used for breaking top leaves on cabbage cabbage.

Peeled from the upper leaves, the bumps are dragged by the conveyor 74 along the grating 22 installed under the conveyor 74 (Fig. 2) and consisting of bars 76 (Fig. 6) arranged so that they form between themselves longitudinal slots along the conveyor of a certain width. Kochny, the passage through the lattice, fall under the roller 78, which is under the influence of the spring20. The loose humps with the roller 78 are forced into the lattice slots and fed to the conveyor 72, and the normal bumps, overcoming the resistance of the spring 20, pass under the roller and with the fingers of the conveyor 74 are dropped onto the conveyor 23, which feeds them into the hopper 24.

The subject matter of the invention.

Claims (4)

1. A harvester, characterized in that, in order to use cabbage stalks for livestock feed, separating them during harvesting from the stump by means of a knife 9-70, a second knife 4-5 is used, which serves to trim from the root stalk. 2. In the machine according to claim 1, use of a conveyor 72 for collecting forage residues of the stalks and a crate 8 for collecting roots cut off from the stalks. 3.In the car on the PP. 1 and 2, placed on the carrying bottom surface of the conveyor 74 and under the influence of the springs 20 of the roller 78, which is used to press the passing cabbage to push the loose buds through the grate 22. 4.In the car on the PP. 1-3, a comb 79 is used to break upper leaves on cabbage heads.
