Description

 The invention relates to the field of agriculture, in particular gardening, and can be used for harvesting from berry bushes, for example, sea buckthorn.

 A known machine for collecting berries, mainly sea buckthorn, containing a frame with a divider installed on it, a vibrator with working bodies in the form of a shaft with fingers, a catcher and a fan, and the fingers of the said working body are made in the form of pieces of spirals, the ends of which are fixed to the shaft along its axis (see the description to the AS of the USSR 704513, according to class A 01 D 46/00, decl. 02.08.77).

 A disadvantage of the known machine is that it does not provide high-quality separation of berries from branches, since the working body transmits oscillatory movements to fruit-bearing branches that do not have additional support. These vibrations are partially damped by the skeletal branches of plants and therefore complete separation of the berries does not occur.

 The use of a divider that separates the bush and directs part of the branches to the working body, leads to significant injury to plants due to breakage of their branches.

 The closest in technical essence and the achieved positive effect (prototype) is a machine for collecting berries from bushes, mainly sea buckthorn, containing a U-shaped frame, activators, vertically mounted on separate symmetrically arranged rectangular frames with the possibility of free rotation, vibration exciter, catchers and mechanism drive (see the description to the AS of the USSR 331777, according to class A 01 D 46/00, decl. 19.10.70).

 This device also does not allow for sufficient completeness of collection of sea buckthorn berries, as it transfers vibration to the entire bush, and not to individual branches that have low rigidity.

 The objective of the present invention is to create such a device that would allow for more complete harvesting of sea buckthorn from the bushes of the stands.

 The problem is solved in that in a known machine for collecting berries, mainly sea buckthorn, containing activators symmetrically placed on a U-shaped frame, vertically mounted on separate rectangular frames with the possibility of free rotation, vibration pathogens, rigidly connected with activators, traps and a drive mechanism, rectangular frames are equipped with horizontally arranged limiters for the branches, spring fingers mounted perpendicular to the plane of the printers are attached to the limiters for the branches rectangular framework activators are in the form of shafts with fixed fingers on them, and activators for the shafts are arranged stops for branches.

 Spring fingers on the limiters for the branches are mounted with the possibility of movement relative to their longitudinal axis.

 A comparative analysis of the claimed technical solution with the known showed that the proposed combination of features is new, has an inventive step and is industrially applicable.

 The invention is illustrated by drawings.

Figure 1 schematically shows a General view of the machine for collecting berries;
Figure 2 is the same, a section along aa;
Figure 3 - section BB, fastening the spring finger.

 The berry picking machine contains a U-shaped frame 2 mounted on a self-propelled chassis 1, on each rack 3 and 4 of which rectangular frames 5 and 6 are symmetrically located, forming an activation chamber. Rectangular frames 5 and 6 are equipped with horizontally mounted limiters 7 for branches to which spring fingers 8 are attached perpendicularly to the plane of rectangular frames 5 in terminal clips 9. Activators made in the form of vertical shafts 10, 11 with rigidly mounted vertical frames 5 and 6 fixed fingers 12, the Vertical shafts 10 and 11 on a rectangular frame 5 and 6 are located behind the limiters 7 for the branches and installed in the bearing units 13 with the possibility of free rotation. Unbalanced vibration exciters 14 are fixed on the vertical shafts 10 and 11, kinematically connected with the drive 15. At the bottom of the U-shaped frame 2, traps 16 are installed. Spring fingers 8 in the terminal clamps 9 on the limiters for the branches are mounted with the possibility of movement relative to their longitudinal axis.

 The machine for collecting berries works as follows.

 Before harvesting, a self-propelled chassis 1 is installed along a number of plants, placing bushes between the posts 3 and 4 of the U-shaped frame 2. Turn on the drive 15, which transfers rotation to unbalanced exciters of oscillations 14. From unbalanced exciters of oscillations 14, mounted on vertical shafts 10, 11 , oscillatory movements are transmitted to the fingers 12. When the self-propelled chassis 1 moves, plants fall between symmetrically located rectangular frames 5 and 6, the bushes are pressed from both sides by stops 7, not allowing the branches to penetrate directly carbon frames 5, 6 to the vertical shafts 10 and 11. In this case, spring fingers 8, attached to the limiters 7 for the branches with terminal clamps 9, located between the branches, create additional support for them. Activators in the form of vertical shafts 10, 11 with fingers 12, freely rolling, transmit oscillatory movements to all branches of the plant. The branches, additionally relying on the spring fingers 8, which are rigidly fixed on the branch guides 7 for the branches, receive additional elasticity, the spring fingers 8 enter resonance with the fingers 12, increasing the vibrations of the branches, which improves the separation of berries.

 Compared with the known technical solutions, the inventive berry picking machine makes it possible to more fully harvest sea buckthorn from the plantation bushes by increasing the stiffness of the branches and enhancing their vibrations.
