Description

The invention relates to mechanical engineering and can be used in the manufacture of hoisting-and-transport devices for vibration processing plants.

By bus No. 513837, a loading device is known, comprising a hopper tiltable by a hoist, supported by means of rollers, on rails that form pivoting arches in the upper part. In order to evenly pour out the contents of the bunker, a vibrator is installed between the turning arcs, which interacts when the bunker is tilting with its wall, made in the form of a membrane.

This device is difficult due to the presence of an additional vibrator, making the wall in the form of a membrane, the presence of chain transmissions, etc.

I 1310175 V 24 V 31/06. 1987 devices are known for returning machining bodies to a vibratory tank installation, made in the form of elevators or conveyors of various designs: scraper, bucket

with autonomous drive. These devices are complex and costly.

Also known is a vibration installation for machining parts mounted inside a container with a device for loading and unloading the working medium, made in the form of an unalloyed flexible conduit permanently connected at one end to the container, and the other to loading and unloading capacity that can be moved with the possibility of changing the angle of inclination. this container for the loading-unloading position and locking the pipeline 1.

However, this device is difficult due to the presence of a lifting device loaded with the body of the container and provides a loading-outgrill only in a hermetically closed volume, provided that the parts are fixed in the container, and its productivity is low because the machining bodies move only by gravity under level difference

The aim of the invention is to simplify the design and increase productivity.

This is achieved by the fact that the device for returning the machining bodies to the vibrating tank of the installation contains a loading and unloading capacity, the walls of which are made obliquely at an angle to its bottom, and their inclination is greater than the angle of repose of the machining bodies (45 °). as well as a pipeline, the lower part of which contains a pneumatic ejector with an intake cone and devices for adjusting the gap between the intake cone section and the bottom of the tank, and the axial position of the air nozzle, for example, with PEDIATOR pairs, and the upper part of the ejector pipe is larger less than 2 times the diameter of the lower pipeline, and has a transfer window with a cross-sectional area not less than 3 times larger than the cross-sectional area of the upper pipeline, and ends with a dispensing rod Avomo, Nij the lower end of which is placed in vibrorezervuar installation, the sleeve and the upper part of the tube formed with perforations, v

The drawing schematically shows the device.

The device for returning the machining bodies to the vibrating tank of the installation contains a loading and unloading tank 1 and a pipeline 2. The lower part of the pipeline 2 ends with an intake cone 3 and together with an air nozzle 4 which is installed with axial adjustment of its position (clearance L), for example, by means of a screw pair 5, and together with the device for adjusting the clearance LI between the lower cut of the intake cone 3 and the bottom of the hopper, made, for example, in the form of a screw pair B, are pneumatic ejector Op. The upper part of the ejector ends with the upper pipe 7 connected to it, no less than 2 times the diameter of the lower pipe 2 and has a distributing window 8 with a cross-sectional area not less than 3 times larger than the cross-sectional area of the upper pipe 7, and ending with the distributing sleeve 9. the lower end of which is placed in the vibrating tank of the installation 10, wherein the sleeve 9 and the upper part of the pipe are made with perforations 11.

It was established experimentally that the execution of the upper pipe 7 is no less than 2 times as large as the diameter of the lower pipe 2 and the dispensing window 8 with a cross-sectional area not less than 3 times larger than the cross-sectional area of the upper pipe 7, with a dispensing sleeve made like and the upper part of the perforated pipe is optimal for conditions of maximally reducing the speed of advancement of the machining bodies in the final section of the pipeline in order to prevent their damage, but not yet causing them to hang and fall backwards.

The vibrating tank is equipped with a discharge hatch (not shown) with tray 12.

The device for returning the machining bodies to the vibrating reservoir of the installation works as follows according to what size the machining bodies are returned to the vibroreservice 10 by means of a screw pair 6, a gap L is set (see drawing), and by the pair 5 a gap Li is there.

At the end of the vibro-processing cycle, the treating bodies are poured into the loading and unloading tank 1 through the hatch and tray. 7) all machining bodies are transferred to the vibratory tank installation.

Such an embodiment of the device for returning the treating bodies to the vibrating tank of the installation in comparison with the known one is simpler due to the lack of a lifting device for lifting above the vibroreservoir of the installation of the loading and unloading tank with the treating bodies and lowering it, and also increases productivity provides a forced transfer (return) of the machining bodies to the vibrating tank of the installation for 3 ... 7 minutes. In the known device, this happens by gravity only under the difference of the levels. All this reduces the cost of installation with the proposed device by about 3% and increases productivity by about 5%.
