Description

The utility model relates to devices for the preparation of semi-finished products and ready-made dishes in public catering and trade enterprises, as well as for the processing of agricultural products in enterprises for processing vegetables, meat, and fish.

A universal machine for rural life is known, containing an electric drive mounted on a frame, a panel with fixed vibration clamps and mounting fingers, a set of replaceable attachments, output shafts located in different planes (patent of the Russian Federation for the invention No. 2028755, IPC A01F 29/00, A47J 29/06 , A23N 15/00 dated 10/08/1992). The disadvantages of this device include the excessive complexity of the design using several output shafts, which require a complex kinematic drive circuit.

A three-stage planetary mechanism of a kitchen appliance is known, consisting of an input shaft, a planetary mechanism with a carrier and a ring gear, mounted with the possibility of rotation relative to the gearbox housing and being a transmission mechanism. Torque from the input shaft is transmitted through a transmission mechanism to three output shafts arranged in a coaxial pattern (Russian Federation patent for invention No. 2615972, IPC A47J 43/08 dated 04/16/2013). The disadvantage of this device is the complex kinematic diagram of the drive, the complexity of manufacturing gears and bevel wheels of the transmission mechanism and the complexity of setting up the mechanism for operation. The complexity of the drive design leads to an increase in the cost of the product and an increase in production time.

The technical result of the utility model is to increase the service life of the machine by increasing the protection of the electric motor and gearbox drive from loads arising during food processing.

The universal kitchen machine is illustrated by drawings, where: figure 1 shows a general view and section AA of the drive mechanism; figure 2 - replaceable actuators.

The drive mechanism of the UKM (Fig. 1) consists of an electric motor 1 connected through the electric motor flange to a replaceable gearbox 2, which is a high-speed or low-speed torque transmission group, located in a protective casing 3, installed on the frame 4 of the flange for installing replaceable actuators 5. On the outside On the surface of the protective casing 3 there are control buttons for the UCM: speed selector knob 6, drive shut-off button “STOP” 7, indicator lamp “NETWORK” 8.

On the outside of the replaceable gearbox 2, on the flange 5 for installing the replaceable actuators, there is a handle 9 with a cam mechanism 10, which serves as a retainer for the shank of the replaceable mechanisms 11. The head of the bolt 12 serves for the correct orientation of the shank 11 when installing the replaceable actuators and their additional fixation in the radial direction.

Replaceable actuators - nozzles - are separate products made in the form of functional units with a unified seat - shank 11 for connection through the installation flange of replaceable actuators 5 to a specific torque transmission group.

The following are used as replaceable actuators - attachments in the UKM: meat grinder 13, whipping and mixing mechanism 14, vegetable cutting and rubbing mechanism 15, sifting mechanism 16, ripper 17, chopping mechanism 18.

The attachments - meat grinder 13, ripper 17 and grinding mechanism 18 - operate at low rotation speeds, the drive is provided by a low-speed torque transmission group.

The attachments - beating and mixing mechanism 14, vegetable cutting and wiping mechanism 17, sifting mechanism 16 - operate at high rotation speeds, the drive is provided by a high-speed torque transmission group.

The high-speed torque transmission group is a gear - spur or helical - cylindrical gear. Low-speed torque transmission group - is a worm-wheel worm gear with an output shaft. In this case, the high-speed torque transmission group transmits rotation coaxially in the plane of the continuation of the electric motor shaft, and the low-speed group transmits rotation in a plane perpendicular to the electric motor shaft. The gear ratios of the low-speed and high-speed torque transmission groups are selected to ensure better operation of replaceable actuators - attachments with certain types of processed products.

The worm gear provides better accuracy in maintaining the transmitted torque. An additional factor is the shorter manufacturing time of a worm gear compared to a cylindrical gear.

The use of a replaceable gearbox by selecting low-speed or high-speed torque transmission groups allows the use of replaceable actuators - attachments with both a vertical and horizontal axis of rotation.

UCM works as follows. After selecting the product to be processed, the selected high-speed or low-speed torque transmission group 2 is installed and connected to the output shaft of the electric motor 1. The flange 5 for installing replaceable actuators is connected through the shank 11 to the actuator - nozzle 13, 14, 15, 16, 17, 18, fix the actuator - the nozzle with the cam mechanism 10. Check the grounding of the electric motor 1 and the reliability of the fixation of the replaceable actuator. The electric motor 1 is switched on, the receiving capacity of the actuators - nozzles 13, 14, 15, 16, 17, 18 - is filled with the processed product and the technological operation of processing the selected product is performed.

The drive of the low-speed torque transmission group operates as follows: rotation from the electric motor 1 is transmitted through a worm gear to the intermediate shaft 19 and then to the drive shaft 20. From the drive shaft 20 of the low-speed group, rotation is transmitted to the drive shaft of the replaceable actuator.

The drive of the high-speed torque transmission group operates as follows: rotation from the electric motor 1 through a system of cylindrical or bevel wheels is transmitted to the intermediate shaft 19 and then to the drive shaft 20. From the drive shaft 20 of the high-speed group, rotation is transmitted to the drive shaft of the replaceable actuator.
