Abstract

This invention relates to agriculture. The purpose of the invention is to increase productivity and reduce damage to the fruit and bark of trees. Fruit harvesting machine contains a splicer 1, made in the form of a pair of roller chains. The outer side of the circuit is connected by plates 7, and the cams 9 are mounted on the inner side. Each vibrator 2 is pivotally mounted between the branches of the agitator 1 and is made in the form of a double arm. One shoulder 12 of the double-arm lever is installed with the ability to interact with the cam 9, and the other with the working branch of the agitator 1. When the machine moves, the cam 9, interacting with the roller 14, cocks the vibrator 2. Under the action of the spring 16, the arm 13 with the roller 15 strikes plate 7, and then through the chain, the pillows and the booms, the shock pulse is transmitted to the fruits and they are showered. 3 il., 2 z.

The invention relates to the field of agriculture and can be used in fruit harvesting machines of continuous action.

The purpose of the invention is to increase productivity and reduce damage to the fruit and bark of trees.

FIG. 1 given the kinematic scheme of the proposed device; in fig. 2 shows section A-A in FIG. one; in fig. 3 - vibrator, top view.

A device for carrying out the in-line cleaning method comprises an agitator 1, made in a visible element with vibrators 2 placed inside it. The relative speed of the agitator 1 is chosen so that its working branch 3, which is in contact with the stem of the tree being processed, remains stationary during operation.

Injector 1 is formed by two roles. It is put into operation if the transfer of a pulsed effect on the fruit is not effective enough.

The continuous cleaning is carried out as follows.

At the entrance of the harvesting unit between the aisles, the parallelogram mechanism 18 presses the active branch 3 of the flexible organ to the stem of the treated tree 10 (or to a group of trees). At the same time, the actuator 20 is turned on, which in the process of movement ensures the mutual immobility of the pillows 8 and the bark of the trees. This eliminates bark damage.

The cam 9, interacting with the idler branch 3 of the flexible organ with the roller 14, cocks the vibrator 2. Under the action of the spring 16, the shoulder 13 with the roller 15 hits the plate 7, and then through the chain, the pillows 8 and the boles the shock pulse is transmitted

4 coils enveloping four spas to 20 fruits and they begin to crumble. There are sprockets 5 on each side. The link of each chain is closest to the vibrator 2, intensively contain flex legs 6, to which vertical plates 7 with pillows 8 are fastened on the outside. Pillows 8 are made, for example, of rubber. On the plates 7 on the inner side are fixed cams 9, made in the form of a wedge. The cam 9 is located in the middle part of the plate 7 and is directed by its tip towards the movement of the flexible organ. Blank branch 10 of the flexible body is supported by the back side of the rollers 11.

The vibrator 2 is made in the form of a spring-loaded lever, the shoulders 12 and 13 of which are facing the opposite agitators. On the shoulder 12 is mounted a roller 14, interacting on the idle branch 10 with cams 9. On the shoulder 13 a pair of rollers 15 are mounted, pressed by a spring 16 to the inner surface of the plate 7. Between the rollers 15 there is provided a space for the passage of the cams 9.

The axes of the sprockets 5 and the vibrator 2 are fixed on the longitudinal beam 17, which by means of the t g 18 forms a parallelogram connection with the frame 19 of the harvester. The t gi 18 are spring-loaded so

The intensity of the vibrations of the tree increases, but the falling fruits do not beat against each other, as some of them are already gone.

When the inertia of the fruit tree is not great, and the stem is thin (for example, in meadow gardens), the efficiency of the pulse effect decreases. In this case, an additional flexible body 21 is inserted into the harvesting unit, artificially increasing the stiffness of the object being shaken.

Claims (3)

1. A fruit harvesting machine containing a frame on which a vibrator is mounted to interact with a shaker made in the form of flexible elements, characterized in that, in order to increase productivity and reduce damage to fruits and bark of trees, each shaker made in the form of a pair of roller chains, which are connected from the outside by plates, and cams are mounted on the inside of the chains; each vibrator is hingedly mounted between the branches of the agitator and 40 Since the flexible body 1 with its 45 working arm is in the form of a two-arm lever, in section 3 it is constantly pressed against a row of trees.

The machine according to claim 1, characterized in that the cam is fixed on the plate and made in the form of a wedge, facing in the direction of movement of the working body. It is put into operation if the transmission of pulsed effects on the fruit is not effective enough. The continuous cleaning is carried out as follows. At the entrance of the harvesting unit between the aisles, the parallelogram mechanism 18 presses the active branch 3 of the flexible organ to the stem of the treated tree 0 (or to a group of trees). At the same time, the actuator 20 is turned on, which in the process of movement ensures the mutual immobility of the pillows 8 and the bark of the trees. This eliminates bark damage. The cam 9, interacting with the idler branch 3 of the flexible organ with the roller 14, cocks the vibrator 2. Under the action of the spring 16, the shoulder 13 with the roller 15 hits the plate 7, and then through the chain, the pillows 8 and the boles the shock pulse is transmitted 0 fruits and they begin to crumble. As the booster approaches the vibrator 2, the fruits and they begin to fall down. As the booster approaches the vibrator 2, the The intensity of the vibrations of the tree increases, but the falling fruits do not beat against each other, as some of them are already gone. When the inertia of the fruit tree is not great, and the stem is thin (for example, in meadow gardens), the efficiency of the pulse effect decreases. In this case, an additional flexible body 21 is inserted into the harvesting unit, artificially increasing the stiffness of the object being shaken. Invention Formula 1. A fruit harvesting machine comprising a frame on which a vibrator is installed for interacting with a shaker made in the form of flexible elements, characterized in that, in order to increase productivity and reduce damage to fruits and bark of trees, each shaker is made as a pair of roller chains, which are connected to the outside by plates, and cams are mounted on the inside of the chains, each vibrator is hingedly mounted between the branches of the agitator and v p p lnen in the form of a two shoulders lever, one shoulder is set to interact with the cams and the other with the working branch of the agitator. 2.
