Description

These devices are of vibro-pneumatic type and contain two rigidly connected and concentrically disposed inner 1 and outer 2 o pipes. In the upper part, the outer pipe 2 has windows 7 and a frame 5 with a vibration actuator 6, and in the lower part, a conical nozzle 8 and spiral blades 9 The inner tube 1 is connected to the pneumatic system by its upper end, and in the lower part it is provided with a spring-loaded sleeve 10 with windows 11. The upper end of the sleeve 10 is below the windows 3 of the inner pipe 1, and the window 1 has a sleeve

The invention relates to the quality control of bulk materials and can be used to sample grain and other bulk products from vehicle bodies in order to determine their physical and biochemical characteristics.

The aim of the invention is to reduce the energy intensity. The sampling process and the metal intensity of the device.

FIG. Shows the sampler initial position; fig 2 is the same end position

The sampler for bulk materials consists of two concentrically arranged tubes - the inner tube 1 and the outer tube 2, the inner tube 1 is connected to the vacuum pneumatic system by the upper end, and has 3 windows and stops 4 on the lower end. The outer tube 2 is fixed on the frame 5 with the upper part vibrodrive 6 "In the upper part, the outer tube 2 has windows 7, and in the lower part it is equipped with a hollow conical nozzle 8 and spiral-shaped blades 99 In the upper part, the inner tube 1 is rigidly connected to the frame 5, and in the lower part - with spiral blades 9 and equipped with basement The sleeve 10, the sleeve 10 has in its lower part a row of windows 11 and stops 12. Between the stops 4 of the inner tube 1 and the stops 12 of the sleeve 10, elastic elements 13 are placed orienting the sleeve 10 in the original half of 32181

10 - below the open part of the cone nozzle 8 of the external pipe 2. When the bottom of the embankment is reached, the device abuts the bottom with the lower end of the sleeve 10, which, under the action of the mass of the device and vibration, removes the elastic elements 13 and is displaced into the cone nozzle 8 of the outer pipe 2, closing off This window 3 of the inner pipe 2 This movement of the sleeve 10 causes a redistribution of air, which, passing through the window 11 of the sleeve 10, transports the rest of the material from the bottom of the 2 kpo

device so that the upper end of the sleeve 10 is in the cavity of the inner pipe 1 below the row of windows 3, and the window of the sleeve 10 is below the open end of the conical nozzle 8 of the outer pipe 2, using a cable 14 mounted on the frame 5 of the outer pipe 2, the device is mounted on a lifting mechanism with the possibility of lifting and

 lowering into

The sampler works as follows

With the help of a lifting mechanism

g The device is lowered into the bulk material embankment. At the moment of entering the embankment, the vibration actuator 6 and the pneumatic system are activated. "As it moves through the embankment, the material fluidizing under

 the action of vibration, through the open end of the sleeve 10 enters it and reaches the windows 3 of the inner tube 1 "The air through the windows 7 of the outer tube 2 passes through the annular space,

5 twists about the spiral blades 9 and through the openings 3 of the inner tube 1 enters it, where it seizes the material and transports it to the pneumatic system discharger. As

Q immersing takes place layer-by-layer material selection and its transportation to the unloader. The presence of a constant tube of material between the windows 3 and the open ends of the sleeve 10 prevents the material from leaking and

proportional sampling over the entire height of the bulk material.

When the bottom of the bulk material embankment is reached, the device abuts the bottom with the lower end of the sleeve 10. Under the action of the mass of the device and vibrating drive forces, the elastic elements 13 are compressed, due to which the sleeve 10 is displaced inside the cone nozzle 8 of the outer pipe 2. The upper end of the sleeve 10 overlaps the windows 3 of the inner pipes 1 and windows 11 of sleeve 10 fall into the internal space of the cone nozzle 8. Such movement of sleeve 10 causes air redistribution, which, passing through windows 11 of sleeve 10, transports the rest of the material, including a and the bottom layer, into the vacuum discharger of the pneumatic system, after which the drive of the lifting mechanism and pneumatic system is turned off

The use of a spring-loaded sleeve eliminates the need for a special actuator.
