Description

The technical field to which the invention relates

The invention relates to the field of agriculture, in particular to fruit growing, and can be used for manual harvesting from trees or shrubs.

State of the art

A device for manual collection of fruits from trees is known, including a box-shaped body with a double-sided double grip having a double recess with parallel double edges, a spring-loaded lever mechanism for crossing the stalk with a drive and a knife-lever, the blade of which is placed in a double grip, a collecting container with an outlet window, orthogonal to the grip, and the attachment point to the pole, as well as in it the inlet of the container is made on its lateral surface, and the mechanism for intersecting the peduncle is made in the form of a knife-lever of the second kind with a fixed axis of rotation at the end opposite from the blade and the drive of the knife-lever in in the form of a spring-loaded rotary counter-mounted lever, also of the second kind, commensurate in length with a knife-lever and pivotally connected to it by a bar in the area of their middle, and two blocks connected in series by a flexible traction - movable for gain in power, the wheel of which is installed at the end of the second lever, and a fixed block for changing direction the action of the force, the wheel of which is mounted on the body, while the axis of the wheel of the stationary block is oriented orthogonal to the pivot axes of the levers. (See RF Patent No. 2306692, CL A01D 46/00, A01D 46/24, A01D 46/26, publ. 09/27/2007).

The disadvantage of the known design is the manual drive of the device, which leads to a decrease in the productivity of the device.

Known universal fruit picker, containing a housing with a lower ring connected to it with a storage device and movable on the axis - the upper ring, as well as the upper ring is fixed on two V-shaped levers with an axis, the spring is retracted upward with the possibility of being driven by a rope with fixed on it rings strung on a pole, while the lower edge of the upper ring tightly intersects the upper edge of the fixed ring and forms scissors for cutting the stalk. (See RF Patent No. 2441360, CL A01D 46/24, publ. 10.02.2012).

The disadvantage of the known design is the manual drive of the device, which leads to a decrease in the productivity of the device.

The closest in technical essence and the achieved effect and taken by the authors for the prototype is a device for shaking off fruits, containing a vibrator and a gripper plug mounted on a holder, and also a vibrator is made in the form of a vane pump, on the rotor shaft of which unbalances are fixed, the holder has the shape of a hollow rod , moreover, the inlet pipe of the vane pump is installed in the holder with the possibility of longitudinal movement and is connected to it by means of a spring, and the outlet is connected to the gripping fork. (See RF Patent No. 2224406, Cl. A01D 46/24, publ. 27.02.2004)

The device has the following disadvantages: the presence of a vane pump leads to the appearance of increased vibration of the device and an increase in weight and size parameters, as well as the use of a fluid under pressure as a drive reduces its reliability.

Disclosure of invention

The objective of the invention is to develop a shaker with increased reliability and productivity, as well as reduced weight and dimensions and vibration.

The technical result, which can be obtained using the proposed design, is reduced to increasing reliability and productivity, as well as reducing vibration and weight and dimensions, due to the use of a linear electric motor to drive the shaker.

The technical result is achieved by the fact that the shaker, containing a grip connected by means of a screw with an anchor, and it is additionally equipped with a linear electric motor located inside the housing and consisting of an armature installed using the lower and upper plain bearings, with a return spring located in the protective glass, fixed with screws, while the linear electric motor is powered from the battery through the breaker and the power button.

Brief Description of Drawings

FIG. - presented a shaker based on a linear electric motor.

Implementation of the invention

The shaker (see Fig.) Consists of a gripper 1, connected with a screw 2 with an armature 3, which is installed using a lower sliding bearing 4 in a linear electric motor 5, and an upper sliding bearing 6 in a housing 7, an on button 8, a breaker 9 and the storage battery 10 installed in the housing 7, the return spring 11 located in the protective sleeve 12, which is fixed to the housing 7 with screws 13 and 14.

The proposed shaker works as follows: when the power button 8 is pressed, a voltage of 24 V is supplied to the linear electric motor 5 through the breaker 9 from the battery 10. Anchor 3 connected by means of a screw 2 with a grip 1, under the influence of electromagnetic forces arising in the linear electric motor 5, comes into motion and moves to the lower position, using the lower sliding bearing 4 and the upper sliding bearing 6, with a force of at least 500 N (not shown in the figure). When the armature 3 reaches the lower position, the breaker 9 cuts off the power of the linear electric motor 5 from the battery 10, while the electromagnetic force acting on the armature 3 disappears, under the action of the return spring 11 fixed with screws 13 and 14 in the protective glass 12, returns to the upper position. Further, the process of operation of the shaker is repeated with the frequency of operation of the breaker 9 equal to 4 Hz, until the power button 8 is turned off. When the power button 8 returns to its initial position, the power supply of the breaker 9 and the linear electric motor 5 from the battery 10 and the armature 3 under the action of the return spring 11 fixed with screws 13 and 14 in the protective glass 12 returns to the upper position.

Due to the use of a gripper 1, connected by a screw 2 with an armature 3 and a linear electric motor 5 driving it, powered through a breaker 9 from a battery 10, the transmission is simplified, as a result, reliability and productivity increase, as well as vibration and weight and dimensions of the shaker are reduced.

To power the linear electric motor 5, a voltage of 24 V from a DC source is required. The linear electric motor 5 of the shaker converts electrical energy into shaking force of at least 500 N, which is necessary for harvesting.

Compared with the prototype and other known technical solutions, the proposed shaker based on a linear electric motor has a number of advantages:

- due to the use of a linear electric motor, the reliability of the shaker increases;

- due to the use of a linear electric motor, productivity is increased;

- due to the use of a linear electric motor, the transmission gear is simplified and, as a result, the weight and dimensions are reduced;

- due to the use of a linear electric motor, vibration of the shaker is reduced.
