Problems solved by technology

[0003] For example, a kind of oscillator disclosed in CN207472647 for detection of agricultural products and a kind of speed-regulating multi-purpose oscillator disclosed in CN207951309 all utilize the vibration tray with jacks to realize the positioning of the test tubes. The hole is a clearance fit, and the vibrating type is prone to collision, resulting in damage to the test tube, that is, the existing oscillator cannot position and fix the test tube well

Embodiment 1

[0022] see Figure 1~4 , in an embodiment of the present invention, an oscillator for agricultural product detection includes an oscillating main body 1 and an oscillating tray 2 installed on the oscillating main body 1, the oscillating tray 2 is provided with a groove, and a groove for clamping a test tube is installed in the groove. Tight and fixed clamping mechanism, specifically, the clamping mechanism includes a fixed frame 6, and two guide rods 7 in parallel positions are installed in the fixed frame 6 through a fixed sleeve 13, between the two guide rods 7 There are a plurality of clamping rods 8, and the two ends of the clamping rods 8 are fixed with guide sleeves 9 slidingly matched with the guide rods 7. The adjacent two guide sleeves 9 are connected by springs 10, and the fixed sleeves 13 are also provided with There are steps 14, and the steps 14 and the guide sleeves 9 are connected by a spring 10, so that when the position of one of the guide sleeves 9 moves, the...

Embodiment 2

[0025] see Figure 2-4 , in the embodiment of the present invention, the clamping blocks 11 have an X-shaped structure, so that a parallelogram-shaped space can be formed between two adjacent clamping blocks 11 for test tubes to pass through. When the distance between them decreases, the space of the parallelogram will also decrease synchronously, and then the test tubes will be clamped. However, if the two opposing clamping blocks 11 are on the same straight line, their positions are likely to interfere, resulting in the inability to adjust the spacing. Therefore, in this embodiment, the two opposing clamping blocks 11 have matching chamfered surfaces 18 , so that the clamping blocks 11 have an isosceles trapezoidal structure, and when the distance between the clamping blocks 11 decreases, the chamfered surfaces 18 can cooperate with each other, so that the positional interference of the clamping blocks 11 will not occur and the situation that they cannot approach each other ...

Embodiment 3

[0028] see image 3 , in the embodiment of the present invention, an oscillator for agricultural product detection also includes a top cover 3 installed on the vibration tray 2, and a 90° flange 4 is provided at the side of the top cover 3, so that the top cover 3 can be clamped on the vibration tray 2, and the clamping mechanism is packaged inside. The top cover 3 is provided with several waist-shaped holes 5, and the space position of the parallelogram formed between the waist-shaped holes 5 and the clamping block 11 Relatively, the design purpose of the waist-shaped hole 5 is intended to be able to adapt to the position adjustment of the test tube when the clamping block 11 moves, and when placing the test tube, the test tube can be directly put into the waist-shaped hole 5, the steps of the test tube and the waist-shaped hole 5 offset, only need to ensure that the test tube passes through the parallelogram space, and then get final product by adjusting the screw rod 15.

Abstract

The invention discloses an oscillator for agricultural product detection, which comprises an oscillating main body and an oscillating tray installed on the oscillating main body. The oscillating tray is provided with a groove, and a clamping mechanism for clamping and fixing a test tube is installed in the groove. The clamping mechanism includes a fixed frame, and two guide rods in parallel positions are installed in the fixed frame through a fixed sleeve, and a plurality of clamping rods are arranged between the two guide rods, and the two ends of the clamping rods are fixed There is a guide sleeve slidingly matched with the guide rod, two adjacent guide sleeves are connected by a spring, and a step is provided on the fixed sleeve, and the step and the guide sleeve are connected by a spring. The beneficial effect of the present invention is: With the design of the clamping mechanism, multiple test tubes can be clamped at one time by operating the adjusting screw, and the designed oblique surface can well avoid the temperature that cannot be adjusted due to the interference of the clamping block position. Its structure is simple and easy to operate. It is convenient and can well ensure the overall stability when shaking.

Description

technical field [0001] The invention relates to a detection device, in particular to an oscillator for detection of agricultural products. Background technique [0002] Oscillators are widely used in electronics industry, medical treatment, scientific research and so on. In the detection of agricultural products, sometimes it is necessary to add reagents to the reagent bottle containing the substance to be tested, and then make a continuous horizontal or vertical reciprocating movement of the reagent bottle to mix the various substances in the reagent bottle evenly and make a detection. [0003] For example, a kind of oscillator disclosed in CN207472647 for detection of agricultural products and a kind of speed-regulating multi-purpose oscillator disclosed in CN207951309 all use the vibration tray with the jack to realize the positioning of the test tube, but during actual operation, the test tube and the insertion The holes are clearance fit, and the vibrating type is pron...
