[0020] The following describes the specific implementation of the present invention in detail in conjunction with specific embodiments.

[0021] Embodiment:

[0022] Please refer to Figure 1 - Figure 6 , an experimental placement rack provided by an embodiment of the present invention includes a bracket assembly 1. The bracket assembly 1 includes a base 101, a support rod 102, and a funnel snap ring 105. Three support rods 102 are fixedly arranged at intervals along the circumference on the top of the base 101. A sand content measuring instrument fixing ring 103 and a sand content measuring instrument snap ring 104 are respectively arranged at the lower part and the upper part of at least one support rod 102. A rubber stopper 107 is arranged on one of the support rods 102. The tops of the support rods 102 are commonly fixedly connected below the snap ring 105. A timer 106 is detachably installed on the funnel snap ring 105. The timer 106 is a stopwatch for timing, which is a well-known prior art with an accuracy of 0.1 s. The design of being detachably installed is because the timer 106 needs to be regularly inspected for quality and needs to maintain accuracy.

[0023] Among them, the bracket assembly 1 provides a stable bracket structure through the combination of the base 101, the support rod 2, the funnel snap ring 105, the sand content measuring instrument fixing ring 103, and the sand content measuring instrument snap ring 104, ensuring the stability of the funnel and the sand content measuring instrument during use. The detachable installation of the timer 106 on the funnel snap ring 105 makes timing more convenient, while the rubber stopper 107 plays a role in blocking the outlet of the funnel 2, so that when adding the sample to be tested into the funnel 2, there is no need to use hands to block the outlet of the sample to be tested in the funnel 2, thus liberating the hands of the operator.

[0024] Please refer to Figure 2 , the funnel snap ring 105 is an open ring.

[0025] Among them, the open-ring design of the funnel snap ring 105 can adapt to funnels 2 of different shapes and sizes, increasing the applicability of the placement rack.

[0026] Please refer to Figure 4 , the sand content measuring instrument fixing ring 103 includes a first clamp 1031 and a second clamp 1032 which are fixedly connected by welding. The first clamp 1031 is detachably connected to the support rod 102 through a fastening bolt. The second clamp 1032 includes a screw 1032a, a knob 1032b, a housing 1032c and a hoop 1032d. One end of the hoop 1032d is fixedly provided with the housing 1032c. A screw 1032a is rotatably installed in the housing 1032c. The other end of the screw 1032a is fixedly connected with the knob 1032b. A plurality of holes which are in clearance fit with the threads on the screw are arranged at intervals at the other end of the hoop 1032d. A slot for the clearance fit of the screw and the holes is opened on the left side of the housing 1032c. And a rubber pad is arranged on the inner surface of the second clamp 1032. The sand content measuring instrument snap ring 104 is two integrally formed third clamps, and openings are arranged in opposite directions on both of the two third clamps. One of the third clamps is clamped on the support rod 102. The rubber plug 107 is connected with a collar through a soft rope. An opening is arranged on one side of the collar and is clamped on the support rod 102. The specific structure of the second clamp 1032 is the prior art that has been publicly disclosed and will not be elaborated here too much.

[0027] The detachable connection design between the sand content measuring instrument fixing ring 103 and the support rod 102 can adjust the height of the sand content measuring instrument fixing ring 103 at any time. And the sand content measuring instrument fixing ring 103 can be fixed through the bolt on the first clamp 1031 of the detachable connection between the sand content measuring instrument fixing ring 103 and the support rod 102. In addition, the second clamp 1032 can drive the screw 1032a to rotate by rotating the knob 1032b, and then drive the hoop 1032d to expand and contract. The rubber pad on the inner surface of the second clamp 1032 of the sand content measuring instrument fixing ring 103 can improve the safety of operation, provide greater flexibility, facilitate the fixing of sand content measuring instruments of different sizes, and improve the convenience of experimental operation.

[0028] When the utility model works, the collection cup 3 and the funnel 2 are placed on the bracket assembly 1, and the collection cup 3 is directly below the funnel 2. The sample outlet of the funnel 2 is blocked by the rubber stopper 107, and then the sample to be tested is injected into the funnel 2. Then the rubber stopper 107 is taken out from the outlet of the funnel 2. At the same time, the timer 106 is started. The sample to be tested enters the collection cup 3. When 946 mL of the sample to be tested enters the collection cup 3, the timing is stopped. During the whole working process, there is no need for one person to hold the funnel and another person to block the liquid outlet of the funnel with hand and hold the timer to time. This reduces the number of operators and makes the operation simple, liberating the hands of the operators. When separation and precipitation are needed, the sample is loaded into the sand content measuring instrument, and the bottom end of the sand content measuring instrument is placed in the second clamp 1032 of the sand content measuring instrument fixing ring 103. The knob 1032b is rotated to drive the bolt 1032a to rotate, and then drive the strap 1032d to tighten, so as to fix the sand content measuring instrument. The upper middle part of the sand content measuring instrument is clamped in the sand content measuring instrument clamping ring 104 for fixation, and the sand content measuring instrument is kept in a vertical state, which is convenient for the substances in the sand content measuring instrument to be statically stratified. When the sand content measuring instrument needs to be taken out, the screw 1032a is rotated in the reverse direction, and the strap 1032d can be loosened.

[0029] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
