Description

(54) POWDER MACHINE

one

The invention relates to agricultural machinery, in particular, to machines for harvesting a year, mainly raspberries.

A known harvester has a frame, two symmetrically mounted conveyors and combing petals 1.

A disadvantage of the known machine is incomplete trapping a year.

Also known harvester, containing the frame mounted on it symmetrically with respect to its axis section of the brush catchers and conveyors 2.

A disadvantage of the known machine is the poor maneuverability of the machine, which leads to a decrease in the year of harvesting from crops whose stem is displaced relative to the axis of their row.

The purpose of the invention is to increase the mavoriness of the harvesting machine and the quality of harvesting year from crops,

strands of which are displaced relative to their row axis.

This goal is achieved by the fact that each section of the catcher is equipped with a spring-loaded transverse movement mechanism, a drum and an elastic apron, one end of which is connected to the brushes, and the other is connected to its axis by means of a spring more abruptly. the mechanism of transverse movement is made in the form of at least two connected hinge four-shafts.

Claims (2)

Berry harvesting contains frame, mounted on it symmetrically about its axis sections of brush catchers and conveyors. Each of the brush catcher sections consists of brushes 1 mounted on the frames of the receiving conveyors 2 by means of a spring-loaded transverse movement mechanism consisting of four-link hinge 3 arranged along conveyors 2 and connected by a common pull 4 to ensure synchronous operation, the spring loading of the four-link 3 springs 5 squeeze 6 conveyors connected to the frame. On top of the four bars 3 of each brush 1 is an elastic apron 7, one end of which is connected to the brush 1 and guide 8 and the other to the drum 9, which is connected to its axis by means of a torsion spring 10 enabling the elastic apron to be wound and rolled up on the frame of each conveyor 2. Berry harvesting machine works in the following way. When the harvester enters the ROW and moves along it, the guide 8, interacting with the sleeper columns and elements of the crown of the bush, periodically deviates from the longitudinal axis of the machine, which leads to an automatic deflection of the brush 1 rigidly connected to the 8 V rail. As a result of these interactions, one of the four bridges 3 folds. T ha, moving in the longitudinal direction, ensures the synchronous operation of all the four bridgers 3 of the spring-loaded transverse displacement mechanism, as a result of which the springs and 5 is compressed. In this case, the brush 1 is displaced strictly parallel to the longitudinal axis of the frame of the machine, and the elastic apron 7 is uniformly wound on the drum 9 rotating under the action of the spring 10 of the twist. At the same time, at this moment, the other section, the catcher with the four-link spring-loaded mechanism, is also displaced due to the force of the spring 5-contraction and thus presses the first section to the brushes, thus forming an uncovered trapping surface. At this moment, the elastic apron 7 of this section is unwound from the drum 9. In this way, with transverse displacements of one section parallel to the longitudinal axis of the other machine, section 9 synchronously moves in the same direction and presses the first section with brushes, while the base area of the plant completely overlaps. Such periodic movement of two sections of the catcher when the harvester deviates from the row axis occurs during the entire time the machine moves along the row. Continuous reciprocating elastic apron 7 provides high-quality gathering of the heap from the catcher to the receiving conveyor 2. The return of the guide 8 and, with it, the base of the brush 1 to its original position is carried out by the compression spring 5, which overcomes the action of the torsion spring 10, since the deformation force of the compression spring 5 is greater than the deformation force of the torsion spring 10. The presence of spring-loaded mechanisms for lateral movement and springs. The elongated drums with an elastic apron allow for a constant pressing of the pile to the elements of the crown of the bush, as well as overlapping the interstitial zone and the zone of the base of the bush, which reduces the loss of a year when catching and increases the maneuverability of the machine. Claim 1. Berry harvesting machine containing a frame mounted on it symmetrically about its axis brushing catcher sections and conveyors, characterized in that, in order to increase the maneuverability of the machine and the quality of harvesting, the year from crops whose stumps are offset from the axis of their row, Each catcher section is equipped with a spring-loaded transverse movement mechanism, a drum and an elastic apron, one end of which is connected to the brushes and the other end to the drum, which is connected to its axis by means of a spring s twist. 2, the machine according to claim 1, characterized in that each transverse movement mechanism is made in the form of at least two connected hinge four-link members.
