[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are one embodiment of this invention, and not all embodiments. Based on the described embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0023] This embodiment provides a spraying sedimentation chamber for verifying acute toxicity testing of silkworms.

[0024] Reference Figure 1 and Figure 2 A spraying and settling chamber for verifying acute toxicity testing of silkworms includes a body 1, a spraying device 2, a support device 3, and a suction device 4. The spraying component 22 and the support device 3 are sequentially arranged inside the body 1, wherein the support device 3 is used to place mulberry leaves, and the spraying component 22 is arranged above the support device 3 and is used to spray the pesticide solution onto the mulberry leaves placed on the support device 3.

[0025] The main body 1 is equipped with a cabinet door that can be opened and closed.

[0026] The spraying device 2 includes a settling cylinder 21 and a spraying assembly 22. A support 5 is horizontally fixed inside the body 1. The support 5 is provided with a mounting hole for the settling cylinder 21 to be vertically inserted. A flange is provided on the lower outer wall of the settling cylinder 21 along its circumferential direction. The flange is used to abut against the upper end face of the support 5 so that the settling cylinder 21 can be vertically inserted into the mounting hole for a certain distance, thereby achieving a stable connection between the support 5 and the settling cylinder 21.

[0027] To ensure uniform settling of the medicine solution within the settling cylinder 21, the upper end of the settling cylinder 21 is designed to gradually expand.

[0028] Reference Figure 3The spraying assembly 22 is located at the top of the settling cylinder 21 and is used to spray the liquid medicine into the settling cylinder 21. It includes a loading plate 221, a wide-angle nozzle 222 and a pulley assembly 223.

[0029] A wide-angle nozzle 222 is mounted on and rotatably connected to a loading tray 221, and extends into the settling cylinder 21. A pulley assembly 223 includes a timing belt and a pair of timing pulleys. The pair of timing pulleys are rotatably connected to the loading tray 221 and connected via the timing belt. One timing pulley is connected to the wide-angle nozzle 222, and the other timing pulley is connected to a drive motor to drive the wide-angle nozzle 222 to rotate via the pulley assembly 223, thereby improving the uniformity of the spray.

[0030] To facilitate disinfection and cleaning of the settling cylinder 21, the spraying assembly 22 and the settling cylinder 21 are movably connected. In a preferred embodiment, the loading tray 221 has a quick-release clamp 2211 at its bottom, which surrounds the extension end of the wide-angle nozzle 222 and can be embedded and clamped into the top of the settling cylinder 21, thus achieving a movable connection between the spraying assembly 22 and the settling cylinder 21 through a movable clamping method. In practice, the movable connection between the spraying assembly 22 and the settling cylinder 21 can also be achieved through movable clips, bolts, etc.

[0031] A solution bottle 2212 connected to the wide-angle nozzle 222 is also fixedly installed on the tray 221 to provide spraying solution to the wide-angle nozzle 222.

[0032] Reference Figure 2 and Figure 4 The supporting device 3 includes a tray 31 for placing multiple mulberry leaves, which is horizontally positioned below the settling cylinder 21.

[0033] In practical implementation, to facilitate the handling of mulberry leaves, the storage tray 31 is movably connected to the machine body 1. A preferred embodiment is that the storage tray 31 has slide bars at both ends along its length, and the machine body 1 has sliding grooves on both sides along its length for the slide bars to slide into. In practical implementation, the movable connection between the storage tray 31 and the machine body 1 can also be achieved through guide rails or similar components.

[0034] To facilitate the collection of waste liquid generated during the experiment, a waste liquid collection tray 6 can also be set below the tray 31. The waste liquid collection tray 6 and the tray 31 are integrated, and the area of ​​the waste liquid collection tray 6 is larger than the area of ​​the tray 31.

[0035] When a waste liquid collection tray 6 is provided, the waste liquid collection tray 6 is movably connected to the body 1, the storage tray 31 is spaced apart from the body 1, and the movable connection method of the waste liquid collection tray 6 is similar to the connection method of the storage tray 31 and the body 1 described above, which will not be repeated in this application.

[0036] Meanwhile, in order to adjust the distance between the bottom of the storage tray 31 and the settling cylinder 21, the storage tray 31 and the waste liquid collection tray 6 can be connected by a telescopic rod.

[0037] Reference Figure 1 and Figure 2 The suction device 4 includes a fan 41, a high-efficiency filter 42, and a low-efficiency filter 43. An air outlet is provided on the top of the body 1. The fan 41 and the high-efficiency filter 42 are both located on the top of the body 1, and the fan 41, the high-efficiency filter 42, and the air outlet are connected in sequence.

[0038] An air inlet is provided at the bottom of the unit 1, and an inefficient filter 43 is located at the bottom of the unit 1 and is connected to the air inlet.

[0039] To ensure smooth airflow within the machine body 1 during the experiment, multiple ventilation holes 61 are evenly distributed along the circumferential direction at the top edge of the waste liquid collection tray 6. Meanwhile, to prevent the liquid from leaking from the ventilation holes 61 to the bottom of the machine body 1 during spraying, a barrier 62 is provided around each ventilation hole 61 on the top of the waste liquid collection tray 6.

[0040] Reference Figure 5 A baffle plate 7 is movably connected between the support 5 and the storage tray 31. The baffle plate 7 is used to be placed between the support 5 and the storage rack after the spraying experiment is completed to shield the storage tray 31 and prevent the liquid adhering to the inner wall of the settling cylinder 21 from falling onto the mulberry leaves placed on the storage tray 31 and affecting the experimental results.

[0041] The implementation principle of the spraying sedimentation chamber for acute toxicity test verification of silkworm in this application embodiment is as follows: When conducting the acute toxicity test verification experiment of silkworm, the fan 41 is first started to vent the inside of the machine body 1; then, multiple mulberry leaves are placed on the storage tray 31 and put into the machine body 1; then the spraying assembly 22 is started to perform the spraying operation. Next, after completing the spraying operation, start the fan 41 again to perform a second evacuation operation inside the machine body 1 to prevent the liquid from leaking to the outside. Finally, place the baffle 7 between the bracket 5 and the storage tray, and take out the storage tray 31 to carry out subsequent experiments.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
