Description

phage. 1 The invention relates to a vibration technique, namely to pneumatic vibration exciters, can be used as a drive for vibration machines in various industries and is an improvement of the device according to the author. St. No. 882863. The purpose of the invention is to reduce the energy intensity of the pneumatic driver. FIG. 1 shows a pneumatic vibration exciter, a general view in section; in fig. 2, - the same, with the upper position of the impactor; incision; in fig. 3-6 - rod, embodiments. The pneumatic vibration exciter consists of a base 1, a drummer 2 with a bypass channel 3, a flexible element 4 and a cuff-valve 5, which form with the base 1 and the drummer 2 without a exhaust chamber 6 through the passage of energy through the channel 7 and the chamber 8 of the reverse . The area of the camera 8 is reverse, from the side of the striker 2 it is larger than the area of the camera of the forward drive. The base 9 is attached to the rod 9, located in the channel 3 of the striker 2. The rod 9 has a cylindrical 10 and a conical 11 parts. A shut-off juice 12 can be made on the cylindrical part, and the rod itself has elements for adjusting its position in channel 3. The pneumatic vibration exciter operates as follows. The energy carrier through channel 7 constantly enters the hopeless chamber 6 of the forward stroke. In the lower position of the striker 2, the rod 9 by the cylindrical part 10 blocks access of the energy carrier from the camera 6 to the forward stroke to the camera 8 in the reverse stroke, which at this moment is in communication with the atmosphere. Under pressure from the energy carrier, the impactor begins to move upwards with acceleration. At some point, the cuff valve 5, pressing against the base 1, seals the chamber 8 of the return stroke, while the conical part 11 of the rod 9 opens the bypass channel 3 and the energy carrier from the forward stroke chamber fills the camera 8 of the return stroke. Since the area of the firing pin 2 from the side of the backstop camera 8 is larger than that from the side of the forward swinging camera, the firing pin 2, after hitting the base 1, begins an accelerated downward movement. Then the cylindrical part 10 of the rod 9 closes the channel 3, and the cuff-valve 5 departs from the base I to depressurize the camera 8 of the return stroke, from where the energy carrier is emitted into the atmosphere. Under the action of pressure in the forward stroke chamber, the impactor 2 slows down movement, stops and starts moving upwards. Then the cycle repeats.
