[0019] 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.

[0020] 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.

[0021] The embodiment provides a spray tower for verifying acute toxicity testing of silkworms.

[0022] Reference Figure 1-4 A spray tower for acute toxicity testing of silkworm includes a body 1. Inside the body 1, a working area 11, a control area 12, and a suction area 13 are arranged sequentially from top to bottom, and the working area 11, the control area 12, and the suction area 13 are mutually enclosed.

[0023] The work area 11 is equipped with a spraying device 2 and a carrying device 3. The carrying device 3 is used to place silkworm leaves, and the spraying device 2 is used to spray medicine onto the silkworm leaves.

[0024] The spraying device 2 includes a settling cylinder 21 and a spraying assembly 22. The settling cylinder 21 is vertically installed in the working area 11 with a tapered top, and its top extends to the outside of the machine body 1. The spraying assembly 22 includes a nozzle 221, which is located at the center of the top of the settling cylinder 21 and is connected to a compressor pump and a liquid pipe.

[0025] In the specific implementation process, in order to facilitate the placement and removal of the settling cylinder 21 and improve the convenience of cleaning and disinfection, the working area 11 is set with an opening on one side and the top, and is equipped with an L-shaped cover plate 14 for covering the opening area. The L-shaped cover plate 14 and the machine body 1 can be connected to each other by magnetic attraction, snap-fit ​​or other means.

[0026] The top and middle of the working area 11 are horizontally provided with support plates 111 with arc-shaped holes 1111, and the settling cylinder 21 is provided with flanges 211 for respectively engaging a pair of arc-shaped holes 1111.

[0027] To further facilitate the easy placement and removal of the settling cylinder 21, a handle is also provided on the settling cylinder 21.

[0028] To facilitate easy access and disinfection of the settling cylinder 21, the nozzle 221 and the settling cylinder 21 are movably connected. The nozzle 221 has multiple connecting strips 2211 evenly arranged along its circumference. These connecting strips 2211 are horizontally positioned and abut against the top flange 211 of the settling cylinder. The top flange 211 of the settling cylinder 21 also has multiple connecting posts evenly arranged along its circumference. Corresponding connecting grooves are provided on the connecting strips 2211 for the connecting posts to be inserted and engaged.

[0029] In addition, to meet the needs of placing the medicine tube, the connecting strip 2211 is also provided with a storage hole that is compatible with the medicine tube.

[0030] The supporting device 3 includes a tray 31 for placing a flat dish with mulberry leaves. The tray 31 is horizontally arranged below the settling cylinder 21 and coaxial with it. The supporting tray can be driven by a cylinder, electric push rod or other means to move up and down in the vertical direction.

[0031] To prevent the petri dish from moving during the experiment, multiple rotating shafts 311 are evenly arranged along the circumferential direction at the edge of the placement tray 31. All rotating shafts 311 are rotatably connected to the placement tray 31 and are eccentrically connected to an eccentric wheel 3111. The eccentric wheel 3111 is rotated to stably clamp the petri dish and make the petri dish concentric with the settling cylinder 21, thus ensuring the stable positioning of the petri dish during the experiment.

[0032] Furthermore, in order to achieve synchronous drive of the rotation of the eccentric wheel 3111, a pulley 3112 is provided at the end of the rotating shaft 311 away from the eccentric wheel 3111, and multiple pulleys 3112 are connected by a synchronous belt 3113.

[0033] Control area 12 is used to house control equipment, such as a PLC control center.

[0034] The suction area 13 is equipped with a suction device 4, which includes a fan 41 and a filter 42. The air outlet of the fan 41 is connected to the outside, and the air inlet is connected to the filter 42. The filter 42 is connected to the working area 11 to ensure a negative pressure environment in the working area 11, prevent the liquid medicine from leaking to the outside, and at the same time achieve air purification and discharge.

[0035] To prevent the atomized medicine from accumulating around the settling cylinder 21 at the top of the working area 11, an air inlet is provided on one side of the top of the machine body 1, and an air vent is provided at the bottom of the working area 11 for connecting to the filter 42. The air inlet and the air vent are spaced apart from each other. The air vent is used to connect to the filter 42 to ensure normal air circulation between the working area 11 and the outside air.

[0036] The implementation principle of the acute toxicity test verification spray tower for silkworms in this application embodiment is as follows: When conducting the acute toxicity test verification for silkworms, a plate containing mulberry leaves is placed on a platform. The plate is fixed in a concentric state with the settling cylinder 21 by the eccentric wheel 3111 structure. The platform moves upward to a position close to the outlet of the settling cylinder 21 to receive the settling spray. The mulberry leaves after spraying the liquid can be fed to the silkworms to verify the acute toxicity of the liquid.

[0037] 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.
