Description

FIG. one

The invention relates to hoisting machines, namely screw conveyors, and can be used in various industries in the transportation of bulk material, as well as a teaching aid.

The purpose of the invention is to provide the ability to control the performance by discretely adjusting the pitch of the screw and adjusting the speed of movement of the material.

FIG. 1 schematically shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

A device for examining a screw conveyor includes a housing 1 with a loading 2 and a discharge 3 branch pipes, a screw 4 housed in the case with a shaft 5 and a screw winding 6 made of elastic tape and fixed inside with hinges 7 mounted on the shaft 5 with the possibility of rotation. and subsequent fixation and one end mounted on the shaft 5. The shaft 5 of the screw 4 is connected to the drive 8 through the coupling 9.

Communication helical winding 6 with sleeves 7 can be carried out, for example, through the finger 10, rigidly mounted on the sleeve 7 and freely in the hole of the spiral winding 6.

The housing 1 is made of two parts: an upper 11 and a lower 12, interconnected with the possibility of movement in the transverse direction and being fixed by a bolted joint 13. The case 1 is made of a transparent material.

In the lower part of the housing 1 along its entire length, there is a string 14 with a leash 15, contacts 16 and a recording device 17, for example, in the form of an electric stopwatch. The lead 15 is mounted to move along the string 14 and interact with the contacts 16.

The housing 1 of the device on the side of the loading nozzle is connected to the base by means of a hinge 18, and behind the discharge nozzle it is connected with a stand 19 and a lock 20.

To regulate the amount of material supply in the loading nozzle 3, a flap 21 is placed. To measure the frequency of rotation of the shaft 5, its end is brought out of the housing 1 and a tachometer 22 is attached to it.

The device works as follows.

The actuator 8 is turned on, the shaft 5 of the screw 4 starts to rotate, the rotation frequency of which is regulated by a tachometer 22. The material supply from the hopper is regulated by the gate 21. Next the material is moved by the screw 4 to the discharge port 3. For

determining and adjusting the performance and speed of movement of the material of the sleeve 7 is moved and rotated on the shaft 5 by the necessary pitch, and then fixed. Moreover, the pitch of the screw can be set constant over the entire length or variable - discrete.

To determine the speed of movement of the material, the leash 15 is shifted to the side

the boot nozzle 2 to the contacts 16, which must be open. When the material is moved, the latter pulls the lead 15, the closing contact 16, thereby turning on the recording device 17, an electric stopwatch. Further, the rate of transportation of the material is determined by known dependencies.

The angle of inclination of the screw housing 5 can also affect the performance of the device and the speed of movement of the material. In order to set different angles of inclination, the lock 20 of the stand 19 is released and the housing 1 is moved to the required angle. Next, turn on the drive 8 again and when moving material do

5 measurements of its speed, productivity and at the same time made a visual observation of the transportation process.
