Description

Technical Field

[0001] The invention relates to the technical field of barley straw active component detection, in particular to a device for detecting active components of fresh barley straw. Background Art

[0002] In addition to providing a large amount of fiber and vitamins, barley grass can be used as a health tea. The peptide amino acids in it effectively support cell manufacturing, cell regeneration, derivation and cell metabolism, which is beneficial for the excretion of toxins in the body. It has a certain beauty-enhancing effect and can be directly and quickly absorbed by the blood. In addition, barley grass also contains potassium, which can accelerate the metabolism of sodium in the human body and prevent high blood pressure. People with high blood pressure can lower their blood pressure by taking barley grass, and eating barley grass regularly can maintain stable blood pressure. In addition to being used as a health tea, barley grass also contains a large amount of starch, which can be used as high-quality feed and provide a large amount of nutrients for herbivores. The meat of animals that eat barley grass is also of higher quality.

[0003] Therefore, barley grass has extremely high planting value. However, during the planting process of barley grass, the planting soil, temperature, moisture and environment used may have a huge impact on the substances it contains. Therefore, during the planting process, it is necessary to conduct regular testing of the active substances it contains, and adjust the planting environment and the fertilizers used according to the test results. Therefore, in order to grow higher-quality barley grass, it is necessary to conduct regular testing of the active ingredients it contains. The traditional active ingredient extraction devices are mostly stirring devices, which take fixed-area samples of the planted plants, grind the plants to obtain juice, and judge the active ingredients contained in them by testing the obtained samples. However, this method is relatively cumbersome, and in the time from sampling to returning to the laboratory for extracting the sample juice, firstly, the sample is easily contaminated by the outside world, and secondly, it is easy to cause sample mixing to affect the test results. Therefore, this example aims to design a fresh barley grass active ingredient detection device that can extract juice samples of barley grass in real time. Summary of the Invention

The function of the valve is to ensure the one-way flowability of the reagent in the chemical hose 122, that is, when the extrusion assembly moves forward, the reagent in the sample capsule 105 can be drawn out and drawn into the chemical hose 122 by negative pressure, and when the extrusion assembly moves back, the reagent sucked into the chemical hose 122 is squeezed out through the diverter tube 124 and the one-way valve 123.

[0039] Useful, such as Figure 1 The extrusion assembly shown in FIG. 1 includes an opening 112 formed in the upper inner wall of the extrusion chamber 121 , wherein the left and right inner walls of the opening 112 are respectively connected to each other and provided with guide grooves 113 , a slider 115 is slidably provided in the opening 112 , and guide sliders 114 that can slide in the guide grooves 113 are respectively fixedly provided on both side end surfaces of the slider 115 ;

[0041] The slider 115 is provided with an opening slot 116 opening downward, and the opening slot 116 is rotatably provided with a roller 117. The lower end of the roller 117 can be pressed against the drug hose 122.

[0042] According to specific usage, two or more rollers 117 may be provided in the opening slot 116 , thereby increasing the stability when pushing the slider 115 to move.

[0043] Advantageously, in order to increase the friction between the lower squeezing block 139 and the squeezing block 141 when they abut against the barley grass, thereby facilitating the extraction of juice from the barley grass, a wedge-shaped block 161 is fixedly and evenly arranged on the lower end surface of the squeezing block 141. The lower end of the wedge-shaped block 161 protrudes out of the lower end opening of the squeezing chamber 121. The upper end surface of the storage tank 133 is evenly and fixedly provided with an offset wedge-shaped block 162 that is offset from the wedge-shaped block 161.

[0044] The wedge block 161 and the offset wedge block 162 are both trapezoidal in shape;

[0045] Jump grooves 155 are respectively provided in the front and rear inner walls of the storage tank 133, and jump blocks 157 extending into the jump groove 155 and sliding in the jump groove 155 are fixedly provided on the front and rear end faces of the lower extrusion block 139. A return spring 156 is fixedly provided between the jump block 157 and the inner wall of the jump groove 155. The misaligned friction between the wedge block 161 and the misaligned wedge block 162 can push the lower extrusion block 139 to slide left and right, so that the barley straw is fully ground and the movable filter hole 163 is connected to the filter hole 165, so that the medicine mixed with barley straw juice enters the space of the storage tank 133.

[0046] Advantageously, a plastic sealing ring 125 is provided between the lower end surface of the upper shell 101 and the upper end surface of the lower shell 135 . The plastic sealing ring 125 is used to increase the sealing performance of the upper shell 101 and the lower shell 135 from the outside after they are closed.

[0047] Advantageously, in order to facilitate sample extraction from longer stems and stalks, notches are provided on the front and rear inner walls of the squeezing chamber 121, and plastic rings are provided at the notches to increase the contact between the lower side of the upper shell 101 and the barley grass stems and leaves.

[0048] Advantageously, a push rod 145 is fixedly provided on the rear end face of the piston push block 146, and a limiting block 144 is fixedly provided at the rear end of the push rod 145. Through the limiting block 144 and the push rod 145, the medicine mixed with barley grass stem and leaf juice stored in the storage tank 133 can be squeezed into the empty sample bag 105 on one side through the filter 153 and the connecting port 147.

[0049] According to the usage, the connection mode between the upper shell 101 and the lower shell 135 can be replaced by a hinge connection to a sliding sleeve connection.

[0050] In the initial state, the lower shell 135 and the upper shell 101 are hinged to each other via the hinge chain 131. At this time, the slider 115 moves backward and upward to the maximum extent in the opening 112. The extrusion block 141 moves downward to the maximum extent in the extrusion chamber 121 under the push of the compression spring 111, and the lower end surface of the extrusion block 141 is flush with the lower end surface of the upper shell 101. The piston push block 146 moves to the left to the maximum extent in the storage tank 133. At this time, the movable filter hole 163 and the filter hole 165 are staggered with each other.

[0051] When the upper shell 101 and the lower shell 135 are initially closed, the lower end of the wedge block 161 and the upper end of the offset wedge block 162 are intertwined with each other;

[0052] When extracting the active ingredient from barley grass using the active ingredient detection device, the user removes several sections of stems and leaves or a section of stem and places them between the upper shell 101 and the lower shell 135. Pressure is applied to close the upper shell 101 and the lower shell 135, thereby clamping the stems and leaves between the squeezing block 141 and the lower squeezing block 139. During the process, the juice in the stem is squeezed out by the friction between the squeezing block 141 and the lower squeezing block 139.

[0053] During this process, the user places a sample capsule 105 containing an extraction agent into the capsule slot 102. The capsule slot 102 on this side is the one connected to the drug inlet tube 171, while the other side of the capsule slot 102 is equipped with an empty sample capsule 105, and the sample capsule 105 on this side is connected to the connection port 147.

[0054] At this time, the user pushes the pressing piece 106 downward and pushes the pressing piece 106 to move forward and backward, thereby driving the slider 115 to move forward and backward, so that the roller 117 squeezes the drug hose 122, and then squeezes the extraction drug in the sample capsule 105 into the space between the squeezing block 141 and the lower squeezing block 139 through negative pressure, so that the drug is fully mixed with the squeezed drug, and during the squeezing process of the slider 115, the squeezing block 141 is subjected to downward pressure. The thrust of the wedge-shaped block 161 and the offset wedge-shaped block 162 causes the barley straw to be squeezed. During this process, the medicine is continuously squeezed into the space between the squeezing block 141 and the lower squeezing block 139. When the movable filter hole 163 is connected to the filter hole 165, the medicine and the juice mixture are filtered into the storage tank 133 through the filter hole 165 and the movable filter hole 163 and stored in the storage tank 133.

[0055] After the extrusion is completed, when the upper housing 101 and the lower housing 135 are closed and the slider 115 is moved back to the maximum extent, the movable filter hole 163 and the filter hole 165 are offset from each other. At this time, the piston pusher 146 is pushed to squeeze the medicinal juice mixture in the storage tank 133 through the reagent upper connecting tube 151 into the empty sample capsule 105 for storage.

[0056] After completing the above operations, the user can directly use clean water to rinse the lower extrusion block 139 and the lower side of the extrusion block 141. After removing the lower extrusion block 139 and the piston push block 146, the space of the storage tank 133 can be rinsed.

[0057] The beneficial effects of the present invention are as follows: the present device is more convenient than the traditional sampling method, and can be carried with you for real-time sampling, avoiding sample mixing and contamination. The present device can be sealed in time after the sample is taken to reduce external contamination. During the sampling process, real-time sampling can be performed according to the user, with high flexibility and convenience. After use, the device can be cleaned with clean water for next use.

[0058] Through the above methods, those skilled in the art can make various changes according to the working mode within the scope of the present invention.
