Abstract

The invention relates to the field of agricultural machinery, in particular, to machines for harvesting grass feeds. The essence of the invention lies in the fact that the mass picked up by the pick-up is fed into the press chamber of the baler and, picked up by the rollers and the swivel conveyor of the lower rear part of the chamber lowered down, starts to rotate, which leads to its compaction. As the mass arrives, the rotary conveyor of the rear lower part of the chamber rises and exerts no significant pressure on the formed roll, the further pressing process occurs under the action of the rotary conveyor of the front part of the chamber, lowered to its lower position. Upon reaching the required mass compaction density, both rotary conveyors rise and occupy their final position, due to the diameter of the pressing chamber. This achieves a high and uniform density of pressing the mass along the entire diameter of the formed roll and eliminates clogging between the two conveyors. The technical result is an increase in the density and uniformity of the pressing of the mass, as well as the reliability of the design of the machine.

Description

The utility model relates to the field of agricultural machinery, in particular to grass feed harvesting machines.

Known balers for harvesting grass feeds in rolls. They have a frame mounted on a wheeled drive, on which there is a pick-up and a constant-pressure compaction chamber formed by chain-slat conveyors. The closest analogues are: GB 2150492, 1985 and SU 1692361, 1991. The press chamber of these presses consists of two parts: front and back; with chain-slat conveyors located on them, the lower branches of which move in the same direction. At the same time, the front part of the pressing chamber is rotatable around the lower driving roller with a conveyor located on it.

A well-known analogue of the round baler works as follows. At the beginning of the pressing process, the front of the chamber is in its lower position. When the unit moves, the picker picks up the mass from the roll and, with the help of the clamping grid, feeds it into the pressing chamber. The mass that enters the bale chamber is immediately driven into rotation by means of rollers, as well as a conveyor in the lower position. As the diameter of the roll increases, the front of the chamber rises and occupies the final position due to the diameter of the bale chamber. After the formation of the roll is complete, the back of the chamber leans back and the roll is unloaded on the field.

Thus, the pressing of the dried grass mass begins immediately upon its entry into the pressing chamber.

As a result of this process, the density of the formed roll is more uniform in diameter. This baler may be suitable for harvesting haylage in rolls with their subsequent packaging in a polymer film. However, when the roll is formed in the known press chamber, the incoming mass is stuffed between the inclined branch of the front conveyor and the rear conveyor. This fact leads to loss of mass and the exit of the baler itself from standing.

The purpose of the utility model: increasing the density and uniformity of pressing the grass mass, as well as the efficiency of the round baler.

Figure 1 shows a diagram of the baler.

The baler consists of a frame 1 with a wheel stroke 2, a drum baler 3, a clamping lattice 4, pressing rollers 5 and 6, a pressing chamber consisting of three parts: front 7, rear upper 8 and rear lower 9; on which chain-slat conveyors are located, the lower branches of which move in the same direction. At the same time, the conveyor of the lower rear part, as well as the conveyor of the front part of the pressing chamber, are made rotatable around the lower driving rollers.

Round baler works as follows.

At the beginning of the pressing process, the rotary conveyor 9 of the rear lower part of the pressing chamber and the rotary conveyor 7 of the front part are in their lower extreme positions 9 'and 7'. When the unit moves along the roll, the drum picker 3 picks up the grass mass from the roll and, using the clamping lattice 4, feeds it into the pressing chamber. The mass that enters the bale chamber is immediately driven into rotation by means of rollers 5 and 6, as well as a conveyor 9 ', which is in the lower position. As the diameter of the formed roll increases, the rotary conveyor of the rear lower part of the pressing chamber rises. Upon reaching a certain diameter of the roll, the rotary conveyor of the front part of the chamber 7 ', lowered to its lower position, also begins to act on it. Further, as the diameter of the roll increases, the rotary conveyors rise and occupy their final position, due to the diameter of the pressing chamber. The finished roll is wrapped with twine and unloaded on the field.

Thus, the grass mass supplied by the drum pick-up, getting into the bale chamber, is immediately rolled in by the rotary conveyor 9 ', and is not stuffed between the front inclined and rear stationary conveyors of the bale chamber, as in the known analogue. In addition, during the entire pressing process, the formed roll is under constant additional pressure of two inclined rotary conveyors, which also allows to increase the density and uniformity of pressing the mass over the entire diameter of the roll.
