Description

Technical Field

[0001] This utility model relates to the field of allelopathic testing devices, and in particular to an allelopathic testing device for plant extracts. Background Technology

[0002] Allelopathic effects in plants involve releasing chemicals into the environment that have direct or indirect harmful effects on other plants. Some allelochemicals can be used as insecticides and herbicides, thereby reducing environmental pollution. Therefore, allelopathic testing is necessary to cultivate new insect-resistant and weed-suppressing varieties.

[0003] Existing technologies, such as Chinese Patent Publication No. CN215297303U, disclose an allelopathic testing device for plant extracts, including a detection shell. A control panel is fixedly installed on the front surface of the detection shell near the center. An atomizing device is fixedly installed on one outer surface of the detection shell near the top. A sealing flip cover is movable on the upper surface of the detection shell. A heating device is fixedly installed on the inner surface of the detection shell near the bottom. Support columns are fixedly installed on the lower surface of the detection shell near the four corners. A support base is fixedly installed on the lower surface of the support columns. The allelopathic testing device for plant extracts described in this invention can atomize the extract and disperse it into the detection shell through the atomizing device. The observation glass protects the chamber from external influences, ensuring a sufficient amount of extract is always present in the chamber and preventing waste from traditional irrigation methods. This also makes the test data more accurate. However, this invention uses a fixed atomizing device, resulting in uneven distribution of the atomized extract, which can easily lead to inaccurate experimental data. Furthermore, the extract is not filtered, and impurities within the extract may also affect the experimental results.

[0004] To address the issue of uneven extract distribution during allelopathic testing, atomized extract offers improved performance and resource savings compared to irrigation methods. However, using fixed spray equipment can lead to uneven extract distribution within the testing area, resulting in inaccurate experimental data. Furthermore, the extract may contain impurities, and atomizing it directly without filtration can also affect the experimental results. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the atomized extract is unevenly distributed during allelopathic testing, and to propose an allelopathic testing device for plant extracts.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an allelopathic testing device for plant extracts, comprising a test chamber, support legs, a door, a fixing column, a detection plate, and an atomizing device. The support legs are fixedly connected to the surface of the test chamber, the door is connected to the top surface of the test chamber via hinges, the fixing column is fixedly connected to the inner surface of the test chamber, the detection plate is fixedly connected to the surface of the fixing column, and the atomizing device is disposed on the surface of the test chamber. The atomizing device includes a secondary chamber, which is fixedly connected to the surface of the test chamber, and the inner surface of the secondary chamber is fixed... A motor is installed, the output end of which passes through the surface of the test chamber and is fixedly connected to a driving bevel gear. A screw is rotatably connected to the inner wall of the test chamber, and a driven bevel gear is fixedly connected to the surface of the screw. The driven bevel gear meshes with the surface of the driving bevel gear. A guide post is fixedly connected to the inner wall of the test chamber, and a movable box is slidably connected to the surface of the guide post. A movable block is threadedly connected to the surface of the screw. A connecting pipe is fixedly connected to the surface of both the movable box and the movable block. An annular tube is fixedly connected to the surface of the connecting pipe, and an atomizing port is provided on the surface of the annular tube.

[0007] Furthermore, a secondary box is fixedly connected to the surface of the test box, a filter box is fixedly connected to the inner surface of the secondary box, a pump body is fixedly installed on the surface of the filter box, a corrugated hose is fixedly connected to the surface of the pump body, and the other end of the corrugated hose is connected through the surface of the movable box.

[0008] Furthermore, the surface of the secondary box is provided with an injection port, and an injection pipe is fixedly connected to the surface of the injection port. The other end of the injection pipe is connected to the surface of the filter box.

[0009] Furthermore, the auxiliary housing has heat dissipation grooves on its surface near the motor, and the number of heat dissipation grooves is multiple and evenly distributed.

[0010] Furthermore, the surface of the filter box is provided with a filter device, which includes a slide groove one and a slide groove two. The slide groove one and the slide groove two are both opened on the same side surface of the filter box. A baffle is slidably connected to the surface of the slide groove one, and a filter screen is slidably connected to the surface of the slide groove two.

[0011] Furthermore, rack plates are fixedly connected to the surfaces of the baffle and the filter screen, and a rotating shaft is rotatably connected to the inner wall of the secondary box. A rotating gear is fixedly connected to one end of the rotating shaft, and the rotating gear meshes with the surface of the rack plate.

[0012] Furthermore, the end of the rotating shaft away from the rotating gear passes through the surface of the secondary box and is fixedly connected to a turntable, and the surface of the secondary box is connected to a secondary door via a hinge.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up an atomizing device, the object to be detected by allelopathic sensing is placed on the detection plate and the chamber door is closed. Plant extract is injected through the injection port, and it enters the filter chamber through the injection tube. Under the action of the pump, it passes through the corrugated hose, the movable box, the connecting pipe and the annular pipe, and is finally sprayed out from the atomizing port. During this process, the motor is started, which causes the active bevel gear to rotate, and then the driven bevel gear drives the screw to rotate, causing the movable block to move up and down on the screw, which in turn drives the connecting pipe and the annular pipe to move up and down, ensuring the uniformity of the spray in the test chamber. The guide column set up allows the annular pipe to move up and down more stably. By setting up the atomizing device and using the annular pipe that can move up and down, the uniformity of the spray in the test chamber is ensured, avoiding uneven distribution of the atomized extract area, which would affect the experimental results. This effectively improves the accuracy of the equipment.

[0015] 2. In this utility model, by setting up a filtration device, rotating the turntable causes the rotating shaft to rotate, which in turn causes the rotating gear to rotate, driving two sets of rack plates to move in opposite directions or towards each other. When injecting the extract, the baffle slides out of the filter box along the first slide groove while the filter screen slides into the filter box along the second slide groove, thereby filtering the extract to avoid impurities affecting the experimental results. After the extract is injected, the baffle slides into the filter box along the first slide groove while the filter screen slides out of the filter box along the second slide groove, sealing the filter box and the injection pipe to prevent extract loss and prevent foreign objects from entering. The auxiliary door can be opened to clean the filter screen that has slid out of the filter box for subsequent use. By setting up a filtration device, the opening and closing of the baffle and the filter screen can be easily adjusted, facilitating the filtration of impurities in the extract while preventing extract loss or foreign objects from entering, thus effectively improving the convenience of the equipment.

[0023] Please see Figure 1-5 This utility model provides a technical solution: an allelopathic testing device for plant extracts, including a test chamber 1, a support leg 2, a door 3, a fixing column 4, a detection plate 5, and an atomizing device 6. The support leg 2 is fixedly connected to the surface of the test chamber 1, the door 3 is connected to the top surface of the test chamber 1 by a hinge, the fixing column 4 is fixedly connected to the inner surface of the test chamber 1, the detection plate 5 is fixedly connected to the surface of the fixing column 4, and the atomizing device 6 is disposed on the surface of the test chamber 1.

[0024] The specific setup and function of its atomizing device 6 and filtering device 7 will be explained below.

[0025] In this embodiment: the atomizing device 6 includes a secondary box 601, which is fixedly connected to the surface of the test box 1. A motor 602 is fixedly installed on the inner surface of the secondary box 601. The output end of the motor 602 passes through the surface of the test box 1 and is fixedly connected to a driving bevel gear 603. A screw 604 is rotatably connected to the inner wall of the test box 1. A driven bevel gear 605 is fixedly connected to the surface of the screw 604. The driven bevel gear 605 meshes with the surface of the driving bevel gear 603. A guide post 606 is fixedly connected to the inner wall of the test box 1. A movable box 607 is slidably connected to the surface of the guide post 606. A movable block 608 is threadedly connected to the surface of the screw 604. A connecting pipe 609 is fixedly connected to the surfaces of both the movable box 607 and the movable block 608. An annular pipe 610 is fixedly connected to the surface of the connecting pipe 609. An atomizing port 611 is provided on the surface of the annular pipe 610.

[0026] The effects achieved by the above components are as follows: starting the motor 602 causes the driving bevel gear 603 to rotate, which in turn causes the driven bevel gear 605 to drive the screw 604 to rotate, causing the movable block 608 to move up and down on the screw 604, while the movable box 607 slides up and down on the guide post 606, thereby driving the connecting pipe 609, the annular pipe 610 and the atomizing port 611 to move up and down, ensuring the uniformity of spraying in the test chamber 1. Setting multiple sets of atomizing ports 611 on the annular pipe 610 is also to ensure that the sprayed material can be evenly diffused. The auxiliary box 601 is set to house the motor 602, and the guide post 606 is set to ensure that the annular pipe 610 can move up and down stably.

[0027] Specifically, a secondary box 612 is fixedly connected to the surface of test box 1, a filter box 613 is fixedly connected to the inner surface of secondary box 612, a pump body 614 is fixedly installed on the surface of filter box 613, a corrugated hose 615 is fixedly connected to the surface of pump body 614, and the other end of corrugated hose 615 is connected to the surface of movable box 607.

[0028] The effect achieved by the above components is as follows: the pump body 614 is activated to transport the extract filtered in the filter box 613 to the movable box 607 through the corrugated hose 615, and then spray it out through the connecting pipe 609, the annular pipe 610 and the atomizing port 611. The corrugated hose 615 is provided to facilitate the up and down movement of the movable box 607.

[0029] Specifically, the surface of the secondary box 612 is provided with an injection port 616, and an injection pipe 617 is fixedly connected to the surface of the injection port 616. The other end of the injection pipe 617 is connected to the surface of the filter box 613.

[0030] The effect achieved by the above components is to inject plant extracts from the injection port 616 and into the filter box 613 through the injection tube 617.

[0031] Specifically, the auxiliary housing 601 has heat dissipation slots 618 on its surface near the motor 602. The number of heat dissipation slots 618 is multiple and they are evenly distributed.

[0032] The effect achieved by the above components is as follows: The heat dissipation slot 618 is set to facilitate the heat dissipation of the motor 602, and to avoid the motor 602 from overheating during long-term operation, which would affect both the lifespan of the motor 602 and the experimental results.

[0033] Specifically, a filter device 7 is provided on the surface of the filter box 613. The filter device 7 includes a first slide 71 and a second slide 72. Both the first slide 71 and the second slide 72 are opened on the same side surface of the filter box 613. A baffle 73 is slidably connected to the surface of the first slide 71, and a filter screen 74 is slidably connected to the surface of the second slide 72.

[0034] The effect achieved by the above components is as follows: when injecting the extract, the baffle 73 slides out of the filter box 613 along the first slide groove 71, while the filter screen 74 slides into the filter box 613 along the second slide groove 72, thereby filtering the extract to avoid impurities affecting the experimental results. After the extract is injected, the baffle 73 slides into the filter box 613 along the first slide groove 71, while the filter screen 74 slides out of the filter box 613 along the second slide groove 72, sealing the filter box 613 and the injection pipe 617 to prevent the extract from being lost and to prevent foreign objects from entering.

[0035] Specifically, rack plates 75 are fixedly connected to the surfaces of baffle 73 and filter screen 74, and a rotating shaft 76 is rotatably connected to the inner wall of auxiliary box 612. A rotating gear 77 is fixedly connected to one end of the rotating shaft 76, and the rotating gear 77 meshes with the surface of rack plate 75.

[0036] The effect achieved by the above components is that the rotating shaft 76 rotates, causing the rotating gear 77 to rotate, which in turn causes the two sets of rack plates 75 to drive the baffle 73 and the filter screen 74 to move towards each other or away from each other.

[0037] Specifically, the end of the rotating shaft 76 away from the rotating gear 77 passes through the surface of the secondary box 612 and is fixedly connected to the turntable 78. The surface of the secondary box 612 is connected to the secondary door 79 by a hinge.

[0038] The effects achieved by the above components are as follows: the turntable 78 is set to facilitate the rotation of the rotating shaft 76, and the secondary door 79 is set to facilitate the cleaning of the filter screen 74 that slides out of the filter box 613 for subsequent use.

[0039] Working Principle: By setting up the atomizing device 6, the object to be detected by allelopathic sensing is placed on the detection tray 5 and the chamber door 3 is closed. Plant extract is injected through the injection port 616, passing through the injection tube 617 into the filter chamber 613. Under the action of the pump body 614, it passes through the corrugated hose 615, the movable chamber 607, the connecting tube 609, and the annular tube 610, finally exiting through the atomizing port 611. During this process, the starting motor 602 causes the driving bevel gear 603 to rotate, which in turn causes the driven bevel gear 605 to drive the screw 604 to rotate, causing the movable block 608 to move up and down on the screw 604. This, in turn, drives the connecting tube 609 and the annular tube 610 to move up and down, ensuring uniform spraying within the test chamber 1. The guide column 606 allows the annular tube 610 to move up and down more stably. By setting up the atomizing device 6 and utilizing the vertically movable annular tube 610, uniform spraying within the test chamber 1 is ensured, preventing uneven distribution of the atomized extract that could affect experimental results. This effectively improves the accuracy of the equipment. To ensure accuracy, a filter device 7 is installed. Rotating the turntable 78 causes the rotating shaft 76 to rotate, which in turn causes the rotating gear 77 to rotate, driving two sets of rack plates 75 to move in opposite directions or towards each other. When injecting the extract, the baffle 73 slides out of the filter box 613 along the first slide groove 71, while the filter screen 74 slides into the filter box 613 along the second slide groove 72. This filters the extract to prevent impurities from affecting the experimental results. After the extract is injected, the baffle 73 slides into the filter box 613 along the first slide groove 71, while the filter screen 74 slides out of the filter box 613 along the second slide groove 72. This seals the filter box 613 and the injection pipe 617 to prevent extract loss and prevent foreign objects from entering. The secondary door 79 can be opened to clean the filter screen 74 that has slid out of the filter box 613 for subsequent use. By setting up the filter device 7, the opening and closing of the baffle 73 and the filter screen 74 can be easily adjusted, facilitating the filtration of impurities in the extract while preventing extract loss or foreign objects from entering, thus effectively improving the convenience of the equipment.
