Description

The invention relates to agriculture, in particular to devices for picking and unwinding stalks of stalk feed.

The aim of the invention is to increase operational reliability by simplifying the design.

In FIG. 1 shows a device for unwinding stalks of stalk feed, side view; figure 2 is the same, a top view.

The device comprises a frame 1 with a running gear 2, a roll rotation mechanism 3, a stripping drum 4, a roll lifting mechanism 5 and an unloading conveyor 6. The roll rotation mechanism 3 comprises a closed tape 7 with upper and lower branches enveloping the drive 8 and driven 9 drums. and also a tension device 10. The mechanism for lifting the roll 5 consists of an arcuate grip 11, pivotally mounted on the frame 1, and the power cylinders 12. The combing drum 4 is pivotally suspended on the levers 13 connected to the power cylinders 14. The tension device 10 consists of a drum 15 rotatably mounted on an axis 16, the ends of which are arranged between the guides 17 with the possibility of reciprocating motion. The axis 17 is provided with springs 18 attached to the axis 19 of the chassis 2.

The device operates as follows.

The combing drum 4, under the action of double-acting power cylinders 14 on the levers 13, is lifted upward to a position that provides free loading of the roll. The grip 11 of the lifting mechanism 5 is lowered to the floor surface and brought under the roll. Then, under the action of two double-acting power cylinders 12, the roll is moved and laid on the tape 7 of the rotation mechanism 3. The leading branch of the tape 7 of the rotation mechanism 3, copying the forming of the roll, takes its shape, while the roll rests on the drive 8 and driven 9 drums, which allows To obtain a stable balance of the roll from unwanted movements when moving the device.

In this position, the roll is transported to a livestock farm. During unwinding of the roll, the rotation mechanism 3 imparts a rotational movement to the roll.

The tooth of the combing drum 4 is removed from the roll feed layer by layer and fed to the unloading conveyor 6. where the feed is fed to the feeders or to the bedding of animals

on livestock farms. As the diameter of the roll decreases, the combing drum 4 on the levers 13 is gradually moved from the upper position to the lower one by means of power cylinders 14. As soon as the diameter of the roll becomes equal to the distance between the centers of the drive 8 and the driven 9 drums, and its mass decreases to the corresponding value, the spring-loaded drum 15 under the action

the spring 18 begins to equalize the tension of the tape 7. Thus, from the action of the tensioning device 10, the upper branch of the tape 7 is leveled, as a result of which the roll approaches the stripping drum 4

and allows you to finish combing a roll of small diameter. The use of the present invention allows to create a simple and reliable design of a device for selecting and unwinding stalks of stalk feed, the use of which will save materials, electricity, fuel and reduce operating costs.
