Description

Technical Field

[0001] The utility model relates to the field of cement fineness detection equipment, in particular to an automatic beating device used in a cement particle sieving instrument. Background Art

[0002] According to GB / T 1345-2005, when testing cement fineness (negative pressure sieving method), cement particles are often adsorbed on the inner end surface of the plastic sieve cover in the form of balls during the test. The specification solves this problem by manually knocking on the sieve cover, but the force of the knock is difficult to control, which is inconvenient and may lead to errors during the test. Sometimes it is easy to forget to knock or the knocking number is insufficient, which makes errors more likely to occur and causes inconvenience during the test. An automatic knocking device is now designed to remove cement particles adsorbed on the sieve cover, replacing the manual knocking operation, thereby improving the accuracy and convenience of the test. Utility Model Content

[0003] In order to solve the problem of cement fineness detection (negative pressure screening method), cement particles are often adsorbed on the inner end surface of the plastic screen cover of the sieve in the form of balls during the test process, which requires manual knocking of the screen cover. However, the knocking force is difficult to control, and sometimes it is easy to forget to knock or the number of knocks is insufficient, which is not convenient during the test process. The present application provides an automatic knocking device for a cement particle screening instrument, wherein an adjustment mechanism is provided at the bottom of the main frame, and the adjustment mechanism can fix the main frame on the upper end surface of the screening instrument. A knocking mechanism is provided in the main frame, and the knocking mechanism can automatically knock on the plastic cover on the upper end of the sieve body in the screening instrument. During the knocking process, the cement particles adsorbed on the inner end surface of the sieve cover of the sieve body can be vibrated and dropped into the sieve body, which can prevent the cement particles from being adsorbed on the inner end surface of the sieve cover of the sieve body in the form of balls. The automatic knocking device can replace the manual knocking operation, which is more convenient to use, reduces the manual error of the test, and improves the accuracy. It can also be used with sieve bodies and sieve covers of different heights.

The rotation of the blades can push the paddle at the front end of the knocking frame to move downward counterclockwise with the rotating shaft as the axis, and the knocking part at the rear end of the knocking frame will rise counterclockwise. When the blades rotate to separate from the paddle, the knocking part at the rear end of the knocking frame will rotate clockwise under the action of gravity and fall, and the knocking part will knock the sieve cover during the falling process.
