In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a special granule analysis of geotechnique is with homogenizing appearance, includes the panel that the level set up to and set up the support in the panel below, be fixed with micro motor on its characterized in that panel, the panel lower part is pasted and is had the antivrbration pad, and the panel below is provided with the axis of rotation, the axis of rotation passes through the connecting band to be connected with the micro motor transmission, is equipped with the roll area in the axis of rotation, sets up chain impeller on the roll area, and micro motor drives the axis of rotation through the connecting band and rotates, drives the chain impeller motion on the roll area then.

Furthermore, the surface of the panel is provided with air holes.

Furthermore, both sides of the lower portion of the panel are provided with two side supports, two ends of the rotating shaft are fixed on the two side supports, the rolling belt and the chain type impeller are located between the two side supports, the measuring cylinder is arranged on the lower portion of the panel, and the two side supports are arranged in the measuring cylinder, so that the rolling belt and the chain type impeller are located in the measuring cylinder.

Furthermore, rubber foot pads are arranged at the bottoms of the brackets at the two sides.

Furthermore, handles are arranged on two sides of the panel.

During a traditional particle analysis test, multiple persons are needed to cooperate, a guide rod type stirrer is manually used in hundreds of test measuring cylinders to stir up and down along the depth of suspension, so that soil particles in the suspension are uniformly distributed, and then the further test is carried out. Time and labor are consumed, and the precision is not high. However, the utility model discloses owing to use motor drive, saved the manpower, place back in the graduated flask, through the reciprocal drive of circulation of impeller, make suspension soil grain evenly distributed wherein, fully reach experimental requirement. The device improves the productivity, improves the test quality and can save labor force.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the novel particle analysis stirring apparatus mainly comprises: 1-a micro motor; 2-air holes; 3-connecting the belt; 4-a handle; 5-a panel; 6-a shock pad; 7-bilateral brackets; 8-a rotating shaft; 9-rolling the belt; 10-chain impellers; 11-a rubber foot pad; 12-measuring cylinder and the like 12. Fig. 2 is a schematic view of the entire structure diagram in a closed state. Wherein, the rotating shaft, the rolling belt and the chain type impeller (shown in figure 3) are the key structures essential to the patent scheme of the utility model.

The upper portion major structure is panel 5, and micro motor 1 is fixed on panel upper portion, and panel upper portion both sides are provided with handle 4, play the effect of removing the integrated device, and the panel surface is provided with bleeder vent 2 simultaneously, and in subsequent stirring process, the emission of the air current of being convenient for, the antivrbration pad 6 is pasted to the panel lower part to prevent stirring in-process panel vibrations from top to bottom, to the harm of graduated flask 12, the material of antivrbration pad can be bakelite or plastics, plays the effect of shock attenuation, buffering. Panel lower part both sides are fixed with both sides support 7, both sides support inside and the panel all is provided with connecting band 3, micro motor passes through the connecting band and links to each other with axis of rotation 8, thereby rotate through the electric drive axis of rotation, drive roll area 9 then, be provided with chain impeller 10 on the roll area, roll along with the roll area under electric drive, thereby stir the suspension, both sides support bottom is provided with the rubber foot pad, prevent that the support from vibrations from top to bottom under electric drive, harm to the graduated flask. As shown in the figure, an upper rotating shaft and a lower rotating shaft are arranged, the two ends of the upper rotating shaft are fixed in bearings positioned at the upper parts of the brackets at the two sides, the two ends of the lower rotating shaft are fixed in bearings positioned at the lower parts of the brackets at the two sides, and the rolling belt is arranged between the upper rotating shaft and the lower rotating shaft.

The stirrer utilizes the bottom of a measuring cylinder with 1000mL as a support, a panel, a bracket, an impeller, a gear and other main components which can be made of light materials such as bakelite, plastic and the like, and has the advantages of simple structure, convenient manufacture, simple and convenient use and simple and easy maintenance. And because the motor is used for driving, the rotating speed of the impeller is uniform, the stirring is sufficient, the labor intensity of personnel is greatly reduced, and the test efficiency and the test precision are improved.
