RU2627279C1 - Mechanical fruit-picking device - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: mechanical fruit-picking device contains a handle and a knife fixed on the handle. The handle is made in the form of two side plates rubberized on the outside and rigidly fixed to each other. The handle is equipped with a trigger with a torsion spring. The trigger is attached to the handle end. The fruit picking device housing is made in the form of two parallel plates. The lower end of the plates is rigidly connected to the free end of the handle. The housing is equipped with an abutment for the trigger in the middle part and with the ribbed support for a peduncle in the upper part. The knife is made in the form of the cutting segment installed between the plates on the axis. The cutting segment has an elongated hyperbolic edge and is connected by a link with a free trigger end.

EFFECT: increased productivity, facilitating the fruit picking process, excluding the fruit damage and ensuring the work safety of collectors.

Description

The invention relates to the field of agricultural engineering, in particular to a device for collecting fruit from trees.

Known pruning shears used for pruning tree branches and removing fruit, including articulated cutting and antiskid knives, spring-loaded handles, a travel stop, made in the form of a protrusion, and a latch (RF Patent No. 2045157, IPC A01G 3/02, 1995).

A disadvantage of the known device is the low productivity of fruit collection and the inconvenience of its use. During operation, it is possible that the hand of the worker is damaged, supporting the fetus.

Known mechanical fruit puller used as a prototype, including a handle and a knife mounted on it (RF Patent No. 160727, IPC A01D 46/24, 2016).

A disadvantage of the known device is that it cannot work without a support platform, it is impossible for them to harvest, for example grapes.

An object of the invention is to increase productivity, a wide range of harvesting of various fruits, eliminating damage to fruits and ensuring the safety of pickers.

The technical task is achieved in that in a mechanical fruit puller, including a handle and a knife fixed to it, according to the invention, the handle, made in the form of two lateral rubberized outside and rigidly fixed to each other plates, is equipped with a trigger with a torsion spring fixed at its end, the knife is equipped with a body made in the form of two parallel plates, the lower end of which is rigidly connected with the free end of the handle, while the body is equipped with a stop for the trigger in the middle part and a ribbed support under the fruit buckle in the upper knife is designed as a segment of the cutting edge with an elongated hyperbolic mounted between the plates on the axis and associated rod with a free end of the trigger.

The invention is illustrated by drawings. In FIG. 1 shows a mechanical fruit picker; in FIG. 2 - the same section along aa; in FIG. 3 - the same section along BB; in FIG. 4 - the same section along BB; in FIG. 5 - node G; in FIG. 6 - node D.

The mechanical fruit puller comprises a handle 1, made in the form of two lateral rubber plates 2 outside, rigidly fixed to each other, a trigger 3 with a torsion spring 4, fixed at its end, the housing is made in the form of two parallel plates 5, the lower end of which is rigidly connected to the free end handles 1. The body is equipped with a stop 6 for the trigger 3 in the middle and ribbed support 7 under the stem 8 in its upper parts. The knife is made in the form of a cutting segment 10 mounted between the plates 2 on the axis 9 with an elongated hyperbolic edge, connected by a rod 11 with the free end of the trigger 3.

Mechanical fruit raiser works as follows. The worker, holding the fetus in one hand, in the second - the handle 1 with the trigger 3, brings the fruit puller to the stem 8 between the cutting segment 10 and the ribbed support 7, after which the worker acts on the trigger 3 and, using the rod 11, rotates the cutting segment 10 , which, smoothly deepening between the plates 5 due to its elongated hyperbolic edge, cuts off the peduncle 8, then the worker releases the trigger 3 and, using the torsion spring, the trigger 3 returns to its original position.

For convenience in operation, the handle 1 of the knife is made in the form of two lateral lateral rubber plates 2, while the support 7 of the stem 8 is ribbed for its reliable engagement.

It is advisable to use a mechanical fruit picker, for example, for harvesting citrus fruits, since the fruits of citrus plants adhere firmly to the stalks and cannot be removed manually, since in this case the integrity of the fruit itself is violated, besides it is convenient for them to work in vineyard orchards.

The use of the proposed mechanical fruit picker allows to increase productivity, facilitate the process of fruit assembly, expand the area of application, eliminate damage to the fruit and ensure the safety of pickers.
