Description

Declared as a utility model, a universal electromechanical drive for honey extractors is used in the field of beekeeping and is designed to be installed in any type of honey extractor for use in stationary and field conditions, for operation in electric mode, with a 12-volt battery or AC mains ~ 220 ÷ 230 Volts and a mains power supply with an output voltage of ± 12 Volts, and in manual mode, in the absence of a battery or mains power supply ± 12 Volts.

Known from practice and literature (1. Encyclopedia of beekeeping, A.I. Rut et al., M., Fiction, MP “Brother”, 1993, pp. 152-158. 2. Beekeeping equipment, inventory and their home-made production, Machichka M., Bratislava, Nature, 1998, pp. 300-310) drives for honey separators are divided into two main types: manual and electromechanical.

Manual drives can be based on single-stage chain, pulley-belt or gear conical or cylindrical gears and a crank for rotation, connected, respectively, with a drive sprocket, drive pulley or gear wheel, with or without an intermediate axis, which drives the honey extractor carousel .

The disadvantages of a manual drive are:

- the need to manually, for a long time, rotate the drive along with a carousel loaded with frames with honey bees, leading to great physical exertion on a person;

- the difficulty of achieving large, stable speeds of rotation of the carousel, which leads to insufficiently complete pumping of honey from bee honeycombs;

- large sizes and weight of sprockets, pulleys, belts and gears;

- the possibility of human injuries, leading to the need to install protective fences for moving parts of the mechanism.

Electric drives installed on the honey separator instead of manual drives and serving to reduce physical stress on a person and achieve large stable speeds of rotation of the carousel, are of three types.

The first type is electric drives based on either a single-phase AC electric motor with an operating voltage of 220-230 Volts and a power of 0.1-0.5 kW with mechanical speed control of the honey extractor carousel using continuously variable friction, hydraulic or belt pulley transmissions with variable gear ratio for smooth control of the carousel rotation speed, or based on an AC electric drill with an operating voltage of 220 ± 230 Volts with an integrated thyristor spindle rotation speed controller and a lead cartridge, which is mounted on the crossbar of the honey separator using clamps.

The disadvantages of such electric drives are:

- the complexity and unreliability of the design;

- their high cost,

- large sizes and weight,

- the presence of life-threatening alternating high-voltage voltage supplied directly to the electric drive installed on the honey extractor,

- the danger of electrical injuries and burns, requiring special electrical insulation, personal protective equipment and protective grounding;

- the risk of mechanical injury and the need for protective fences;

- high noise level during operation;

- the impossibility of using such electrified honey extractors in the field in the absence of an AC mains voltage of 220 ÷ 230 Volts.

The second type of electric drive is made on the basis of a car DC generator, powered by a car battery and rotating the honey separator carousel through a gear or belt pulley.

The disadvantages of this drive are:

- the inability to use the honey extractor in manual mode in the event of a battery discharge or the absence of a mains power supply having a constant current output of ± 12 volts;

- large dimensions and weight,

- unreliability of fastenings;

- increased noise and vibration during operation;

- large electrical power consumption (about 160 watts), leading to a fast discharge of the battery.

The third type of electric drive includes an electric drive based on an automobile electric motor from a wiper, which is the prototype of the proposed utility model, which is also powered by a car battery or mains power supply that has a constant current output of ± 12 volts.

The disadvantages of this drive are:

- the difficulty of using the honey extractor in manual mode in the event of a battery discharge or the absence of a mains power supply with an output voltage of ± 12 volts; a big waste of time for the complete dismantling of the electric drive and the installation of a manual drive, if at all possible;

- insufficient power and low torque on the motor shaft leads to the necessity of pushing the honey separator carousel by hand to give it the initial rotation speed at start-up.

The technical problem, which this utility model is aimed at, is the creation of a universal electromechanical drive for the honey extractor, free from the above disadvantages, combining ease of use, the advantages of manual and electric drives with the possibility of easy and quick, within 2-3 minutes, transition from manual to electric operation and vice versa, capable of operating as if there is a safe low-voltage direct current source with an output voltage of ± 12 Volts (automobile battery or mains power supply, operating from an alternating current network with a voltage of ~ 220 ÷ 230 Volts), and in its absence, both in stationary and in field conditions, having low electrical power (less than 50 W) and high torque on the shaft (more than 8 kg / cm), having mechanical and electrical safety during operation, small dimensions and weight, low noise and vibration, high reliability and aesthetic appearance.

The technical result is achieved by the fact that the universal electromechanical drive consists of two drives - electric and manual.

An electric drive designed for operation of the honey extractor in electric mode, in the presence of a DC power source with an output voltage of ± 12 Volts, which can be a car 12-volt battery or a power supply unit, powered from an alternating current main with a voltage of ~ 220 ÷ 230 Volt, consists of a control panel, providing a change in the direction and speed of rotation of the carousel, a compensating clutch, transmitting torque from the shaft of the gear motor to the shaft of the carousel with their compensation misaligned ti, the U-shaped bracket and a miniature motor-reducer, consisting of a 12-volt DC motor with a small electric power consumption (less than 50

W) and an electric drive gearbox with high torque on the shaft (more than 8 kg / cm), which are used to actuate the honey extractor in electric mode and reduce the angular speed of rotation of the carousel.

A manual drive designed to operate the honey extractor in manual mode in the absence of a ± 12 Volt power supply consists of a handle and a gearbox, which serves to increase the angular speed of rotation of the carousel and is a single-stage cylindrical gear in which the teeth of a wheel rotated by a handle mounted on it, mesh with the teeth of the gear rigidly fixed to the shaft of the carousel.

The honey extractor easily and quickly, within 2–3 minutes, is switched from electric to manual operation by unscrewing two bolts to remove the U-shaped bracket from the crossbeam together with the gear motor and coupling, and securing the handle with two bolts to the gear wheel of the manual drive . To transfer the honey extractor from manual to electric operation, the opposite actions are performed in the reverse order.

The use of this universal electromechanical drive allows the honey extractor to be used both in electric mode in field and stationary conditions with a car battery or a power supply unit operating from a network of ~ 220 ÷ 230 Volts with an output voltage of ± 12 Volts, or in manual mode, in the absence of a battery or mains power supply and mains ~ 220 ÷ 230 Volts.

The power supply of the electromechanical drive with direct current of low voltage and the closed design of all rotating parts made it possible to achieve complete mechanical and electrical safety.

The universal electromechanical drive for the honey separator, consisting of two drives: electric and manual, is intended for use both in stationary and in field conditions, both in electric mode, with a ± 12 Volt power supply, and in manual mode, in the absence thereof .

An electric drive designed for operation of the honey extractor in electric mode with a DC power source with an output voltage of ± 12 Volts, which can be a car 12-volt battery or a power supply unit, powered from an alternating current main with a voltage of ~ 220 ÷ 230 Volts , consists of a control panel (2), powered by a ± 12 V power supply (1) and regulating the direction and rotation speed of a miniature gear motor (3, 17), consisting of a 12-volt DC motor (17) with low consumed electric power (less than 50 W), which is used to actuate the honey extractor in electric mode, and an electric drive gearbox (3) with a large torque (more than 8 kg / cm) on the shaft (4), designed to reduce the angular speed of rotation carousel, compensating clutch (6), necessary for transmitting torque from the shaft of the gear motor to the shaft of the carousel (11) with compensation for their misalignment, mounted on the shaft of the gear motor with a screw (5), U-shaped bracket (8), with a gear motor mounted on it Hur with coupling, fixed to the crossbeam (10) with two bolts (9, 13). The input of the control panel is connected to the output terminals of the ± 12 V power supply using removable clamps, one of which, marked “+”, is connected to the positive terminal, and the second, marked “-”, is connected to the negative terminal of the power source. The output of the control panel through the XI connector is connected to the terminals of the gearmotor.

A manual drive designed to operate the honey extractor in manual mode in the absence of a ± 12 V power supply, consisting of a handle (12) and a gearbox used to increase the angular speed of rotation of the carousel, which is a single-stage cylindrical gear in which the gears of the wheel (14) rotate a handle mounted on it, mesh with the teeth of the gear (7), rigidly fixed to the shaft of the carousel. The handle, driven by the human hand, is fixed to the wheel with two bolts screwed into internal threads (15, 16).

The honey extractor easily and quickly, within 2-3 minutes, is switched from electric to manual operation by unscrewing two bolts to remove the U-shaped bracket from the crossbar together with the gear motor and clutch, and securing the handle with two bolts to the gear wheel of the manual drive . To transfer from manual to electric operation, the opposite actions are performed in the reverse order.

The device operates as follows:

To transfer the honey extractor from electric to manual operation, you must first remove the electric drive from the crossbar (10), having previously unscrewed the two bolts (9, 13) securing the U-shaped bracket (8) with the gear motor (3, 17) and the coupling ( 6) to the crossbar, then with two bolts screwed into the internal threads (15, 16), firmly fix the handle (12) on the wheel (14) of the manual gearbox, which serves to increase the angular speed of rotation of the carousel and is a single-stage cylindrical gear. The rotational moment from the handle, driven into rotation by a person’s hand, is transmitted to the wheel, and from it to the gear (7) through their teeth engaging. Then the torque is transmitted to the carousel shaft from the gear rigidly fixed to it.

To transfer the honey extractor from manual to electric operation, you must first remove the handle from the gear wheel of the manual drive, unscrew the two bolts from the internal threads of the wheel, then install the electric drive, securing the U-bracket to the crossbar with two bolts, together with the gear motor attached to it and clutch. Having connected the removable clamps of the control panel (2) in the required polarity to the ± 12 Volt power supply (1) and setting the direction and rotation speed of the carousel on the remote control, we activate the gear motor, which serves to rotate the carousel and reduce its angular velocity. The compensating coupling, rigidly fixed to the shaft of the gear motor (4) with the screw (5), is used to transmit torque from the gear motor shaft to the carousel shaft with compensation for their misalignment in the radial and axial directions.
