A New Tap Density Meter

Abstract

The invention discloses a novel tap density meter comprising a slide bar, wherein a measuring cylinder seat is fixed at the top part of the slide bar, a nylon bulb is connected at the bottom part of the slide bar, a cam with a curve outline is arranged at the lower part of the nylon bulb, and the cam is connected with a motor; the slide bar is matched with a wheel disc groove; the cam is coaxially provided with a pinion, a rack wheel is arranged at the upper part of the pinion, and a shifting block is arranged on the rack wheel; a wheel disc rod is arranged on the wheel disc, and the shifting block shifts the wheel disc to rotate through the wheel disc rod. The novel tap density meter disclosed by the invention has the following beneficial effects: 1. a key slot is arranged in the side face of the slide bar, the key slot is matched with the wheel disc, the pinion obtains a rotating torque from a motor, the torque is transmitted to the rack wheel, the rack wheel is provided with the shifting block, the shifting block shifts the wheel disc, and the wheel disc drives the slide bar so as to enable the slide bar to rotate in the circumferential direction; and 2. the slide bar has different lengths so as to achieve a target of adjustable amplitude.

Description

technical field [0001] The invention relates to the field of instruments and meters, in particular to a tap density meter, in particular to a tap density meter with a vibrating rod that can rotate circumferentially. Background technique [0002] Tap density means that after filling a certain amount of powder into a specific container, vibrate at a certain frequency and amplitude, read the volume of the powder when the volume of the powder no longer decreases, and then divide the weight of the powder by the volume The tap density is obtained. Tap density meters are widely used in metallurgy, powder and other scientific research fields. At present, tap density meters widely used generally have a constant amplitude, and the vibrating rod cannot rotate circumferentially. In order to solve this technical problem, Chinese patent application number: 201120200897.4 application date: 2011-06-15, titled "a new tap density meter" discloses a structure, but the structure is to ensure t...

Tap density meters are widely used in metallurgy, powder and other scientific research fields. At present, tap density meters widely used generally have a constant amplitude, and the vibrating rod cannot rotate circumferentially.

In order to solve this technical problem, Chinese patent application number: 201120200897.4 application date: 2011-06-15, titled "a new tap density meter" discloses a structure, but the structure is to ensure the axial rotation of the vibrating rod, The structure of the rotating motor is adopted. Since the structure uses two motors, one for vibration and the other for rotation, the structure is complex and costly, and it is prone to failure
