Description

Technical Field

[0001] The utility model belongs to the technical field of pesticide detection, and in particular relates to a field pesticide toxicity test detection device. Background Art

[0002] In a broad sense, pesticides refer to a substance or mixture of substances and their preparations that are chemically synthesized or derived from organisms, other natural products, and applied biotechnology, used to prevent, eliminate or control diseases, insects, weeds and other harmful organisms that endanger agriculture and forestry, as well as to purposefully regulate, control, and influence the metabolism, growth, development, and reproduction of plants and harmful organisms. In a narrow sense, it refers to a general term for a class of drugs used in agricultural production to kill insects, sterilize, and kill harmful animals (or weeds) to protect and promote the growth of plants and crops. It specifically refers to agents used in agriculture to prevent and control diseases and insects, regulate plant growth, and kill weeds.

[0003] In the process of producing herbicidal pesticides, it is generally necessary to test the toxicity of the pesticides using a detection device. Referring to a pesticide toxicity detection device with the publication number CN221038955U, the patent uses a test paper to detect the toxicity of the pesticide during use. Although the toxicity of the pesticide can be detected, the result detected by the test paper is only a numerical value, which cannot directly determine the toxicity of the herbicidal pesticide to different types of weeds, making it inconvenient for people to use. Utility Model Content

DETAILED DESCRIPTION

[0019] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 - Figure 5 As shown, a field pesticide toxicity test detection device includes a base plate 1, multiple supporting legs installed on the top of the base plate 1, and a detection platform 2 installed on the top of the multiple supporting legs. A feed pipe 3 is installed at the center of the top of the detection platform 2 and extends into the detection platform 2. The top of the detection platform 2 is provided with multiple groups of detection mechanisms arranged around the feed pipe 3. The detection mechanism includes a detection cavity 11 opened in the detection platform 2, a strip groove 5 opened on the top of the detection platform 2 and connected to the detection cavity 11, and multiple arc grooves 15 opened on the inner walls on both sides of the strip groove 5, and each adjacent two arc grooves 15 are arranged correspondingly. When weeds are located between the corresponding two arc grooves 15, the two correspondingly arranged arc grooves 15 can limit the weeds and reduce the situation of weeds falling over. A feed hopper 4 connected to the feed pipe 3 is installed on the top of the feed pipe 3, and multiple liquid inlet pipes 14 are installed on the outside of the feed pipe 3, and the multiple liquid inlet pipes 14 extend into multiple detection cavities 11 respectively.

[0022] It should be noted that, when using this field pesticide toxicity test detection device, multiple weeds of the same type are inserted into the same strip groove 5 together, and the weeds will be located between the two corresponding arc grooves 15. At this time, the bottom of the weeds will be located in the detection cavity 11. Since multiple detection mechanisms are provided on the top of the detection platform 2, different types of weeds can be inserted into the multiple strip grooves 5 at the same time, and then the pesticide diluted with water is poured into the interior of the feed pipe 3 through the feed hopper 4. The pesticide entering the feed pipe 3 will be discharged into the multiple detection cavities 11 through the multiple liquid inlet pipes 14. At this time, the weeds inside the detection cavity 11 will come into contact with the pesticide. The situation of different types of weeds can be observed every hour, and the situation of different types of weeds can be recorded during the observation process, so that the toxicity of the same concentration of pesticides on different types of weeds can be directly judged, so that the toxicity of the pesticide can be better judged, which is more convenient for people to use.

[0023] Example 2

[0024] Combine Figure 1 - Figure 5 As shown, the difference between this embodiment and embodiment 1 is that: the interior of the detection chamber 11 is slidably connected with a push plate 13 that passes through the strip groove 5 and extends to the top of the detection platform 2, and an opening is provided on the push plate 13 for use with the liquid inlet pipe 14. The outside of the feed pipe 3 is equipped with a driving mechanism for pushing the push plate 13 to move along the detection chamber 11. The driving mechanism includes a fixed ring 6 installed on the outside of the feed pipe 3, a moving ring 8 sleeved on the outside of the feed pipe 3 and located at the bottom of the fixed ring 6, and an electric telescopic rod 7 installed at the bottom of the fixed ring 6. The output end of the electric telescopic rod 7 is fixedly connected to the bottom of the moving ring 8, and the bottom of the moving ring 8 is hinged with a push rod 9, and the bottom end of the push rod 9 is hinged to the top of the push plate 13. A discharge port is provided at the edge of the detection chamber 11 near the detection platform 2, and the discharge port is sealed by a sealing block 12. A connecting rod is installed between the push plate 13 and the sealing block 12. Rod 16, a moving cavity 17 is opened in the detection table 2, and the internal sliding connection of the moving cavity 17 is limited to a limit block 19. A limit rod 18 extending to the outside of the detection table 2 is installed on one side of the limit block 19. The limit rod 18 is located at one end outside the detection table 2 and is installed with a connecting plate 10 fixedly connected to one side of the sealing block 12. When the push plate 13 moves, the sealing block 12 will move under the drive of the connecting rod 16, thereby opening the discharge port. When the sealing block 12 moves, it will drive the connecting plate 10 to move. At this time, the limit rod 18 will drive the limit block 19 to slide inside the moving cavity 17, so that the sealing block 12 can be limited, thereby indirectly limiting the push plate 13, thereby preventing the push plate 13 from deviating during the movement. A plurality of material receiving boxes located at the bottom of the discharge port of the detection cavity 11 are placed on the top of the bottom plate 1.

[0025] A further improved feature of this embodiment is that: after the toxicity test of the pesticide is completed, the electric telescopic rod 7 will drive the movable ring 8 to move downward. At this time, under the action of the push rod 9, the push plate 13 will move along the detection chamber 11, thereby pushing the weeds after the test through the discharge port. The pushed weeds will fall directly into the receiving box, thereby reducing the trouble of manual cleaning and reducing the workload of the staff.

[0026] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
