An adjustable cement mortar vibrator

Abstract

The invention discloses an adjustable cement mortar joilting table.The adjustable cement mortar joilting table comprises a base, a rotating shaft support is vertically connected to the upper surface of the left side of the base, a rotating shaft is mounted at the top end of the rotating shaft support, a rocker arm is hinged to the rotating shaft support through the rotating shaft, a first spring seat is arranged in the middle of the right side of the rocker arm, a fixed column is vertically connected to the top end of the rocker arm, a joilting table top is horizontally arranged on the fixed column, a mounting rack is vertically connected to the middle of the upper surface of the base, and a support frame is vertically connected to the right side of the upper surface of the base.According to the adjustable cement mortar joilting table, a pulling and pressing spring is clamped between a rotating disc and the rocker arm, rotation of the rotating disc and elastic force of the pulling and pressing spring serve as power to drive the rocker arm to vibrate up and down, the pulling and pressing spring is convenient to replace, the vibration force and effect are guaranteed, an upper leading screw cooperates with a lower leading screw, vertical vibration amplitude of the joilting table top is adjusted, and two-sided vibration of the table joilting table top can be achieved.

Description

technical field [0001] The invention relates to the technical field of mortar test body processing equipment, in particular to an adjustable cement mortar vibrating table. Background technique [0002] The cement mortar vibrating table is a kind of equipment suitable for the production of cement strength test samples. When using it, fix the empty test mold and the mold cover on the vibrating table, and use a suitable spoon to directly divide the mortar into two parts from the mixing pot. Put the layer into the test mold. When installing the first layer, put in the plastic sand and level the material layer, then vibrate for 60 times, then load the second layer of plastic sand, level the second layer of plastic sand, and vibrate for 60 times , Remove the test mold after completion, and the sample is completed. [0003] The cement mortar vibrating tables in the prior art all use cams as the vibration force transmission mechanism. After using for a period of time, the cams will...

Problems solved by technology

[0003] The cement mortar vibrating tables in the prior art all use cams as the vibration force transmission mechanism. After using for a period of time, the cams will be worn to a certain extent, which will affect the height of the table top lifting, thereby affecting the force when falling, thus It affects the effect of vibration, and the current plastic sand vibrating table still has the disadvantage that it cannot effectively adjust the vibration amplitude and can only vibrate on one side
