Description

Technical Field

[0001] This utility model relates to the field of snail biometrics, and in particular to an indoor snail biometrics device. Background Technology

[0002] In agricultural production and pesticide research, efficacy testing of snail-killing agents is crucial, but traditional snail efficacy testing faces numerous challenges. In indoor environments, there is a lack of effective devices to simulate snails feeding on crops in their natural environment, making accurate efficacy testing impossible. The indoor environment cannot realistically reproduce the snails' survival and feeding conditions, making it difficult to assess the effects of stomach poisons and contact poisons. Outdoor experiments are severely limited by weather conditions; rainy days and nighttime not only inconvenience experimental operations but also make efficacy observation extremely difficult. There has been no simple and easily observable indoor experimental method or device for testing the efficacy and duration of action of a pesticide. Outdoor experiments also lack suitable testing sites. Therefore, we propose an indoor snail bioassay device to address these problems. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the prior art by proposing an indoor snail biometric device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An indoor snail bioassay device includes a hydroponic box filled with nutrient solution. Inside the hydroponic box is a planting board with evenly distributed cultivation troughs. Seeds are placed in the cultivation troughs. The top of the hydroponic box has a lid that can close the top opening. The lid has openings for ventilation and pesticide evaporation. Inside the hydroponic box is a lifting assembly that drives the raising and lowering of the planting board and the lid.

[0006] Preferably, a three-pronged pipe is inserted through the top of the box cover, the top end of the three-pronged pipe passes through the box cover and is used for adding medicine, and the other two ends of the three-pronged pipe are located below the box cover and are equipped with nozzles.

[0007] Preferably, the hydroponic box is provided with a water inlet and a water outlet on the left and right sides respectively, and the outer sides of the water inlet and the water outlet are respectively threaded with screw caps, and the height of the water inlet is higher than the height of the water outlet.

[0008] Preferably, the lifting assembly includes a bidirectional screw rotatably mounted inside the hydroponic tank via a sealed bearing. Two spaced-apart threaded sleeves are threaded onto the bidirectional screw, and push rods are hinged between the tops of the two threaded sleeves and the bottom of the planting plate, respectively.

[0009] Preferably, a number of connecting rods are fixedly connected between the top of the planting board and the bottom of the box cover, and the number of connecting rods is four and they fit against the four corners of the inner wall of the hydroponic box.

[0010] Preferably, the inner wall of the hydroponic box is provided with sliding grooves on both the left and right sides, and the planting plate is fixedly connected to the two sides of the sliding groove with limiting plates that slide up and down along the sliding groove.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figure 1-4 As shown, this utility model provides an indoor snail bioassay device, including a hydroponic box 1, into which nutrient solution is injected. A planting board 2 is provided inside the hydroponic box 1, and evenly distributed cultivation troughs 3 are provided on the planting board 2. Seeds are placed in the cultivation troughs 3. A box cover 4 is provided on the top of the hydroponic box 1 to close the top opening of the hydroponic box 1. The box cover 4 has through holes 5 for ventilation and chemical evaporation. A lifting component 6 is provided inside the hydroponic box 1, which drives the planting board 2 and the box cover 4 to rise and fall.

[0023] In this embodiment, a three-pronged pipe 7 is inserted through the top of the box cover 4. The top end of the three-pronged pipe 7 passes through the box cover 4 and is used to add medicine. The other two ends of the three-pronged pipe 7 are located below the box cover 4 and are equipped with nozzles 8.

[0024] In this embodiment, the hydroponic box 1 is provided with an inlet 9 and an outlet 10 on the left and right sides respectively. The outer sides of the inlet 9 and the outlet 10 are respectively threaded with a cap 11. The height of the inlet 9 is higher than the height of the outlet 10. The culture medium in the hydroponic box 1 can be released by manually opening the cap 11 of the outlet 10. Then the culture medium can be added through the inlet 9.

[0025] In this embodiment, the lifting assembly 6 includes a bidirectional screw 61 rotatably mounted in the hydroponic tank 1 via a sealed bearing. Two spaced-apart sleeves 62 are threadedly connected to the bidirectional screw 61. Push rods 63 are hinged between the top of the two sleeves 62 and the bottom of the planting plate 2, respectively. The bidirectional screw 61 rotates and moves the sleeves 62 through threaded transmission, and then pushes the planting plate 2 up and down through the push rods 63.

[0026] In this embodiment, a number of connecting rods 12 are fixedly connected between the top of the planting board 2 and the bottom of the box cover 4. There are four connecting rods 12, which fit against the four corners of the inner wall of the hydroponic box 1. During the lifting and lowering of the planting board 2, the box cover 4 can be moved synchronously through the connecting rods 12.

[0027] In this embodiment, the inner wall of the hydroponic box 1 is provided with sliding grooves 13 on both the left and right sides. The planting plate 2 is fixedly connected to the two sides of the sliding groove 13 and the limiting plate 14 slides up and down along the sliding groove 13. When the top of the limiting plate 14 contacts the inner top wall of the sliding groove 13, the top of the planting plate 2 is flush with the top of the hydroponic box 1. The limiting plate 14 moves in the sliding groove 13 to limit the planting plate 2, so that it moves stably and will not move out of the hydroponic box 1.

[0028] In this embodiment, the two push rods 63 are arranged in an inverted figure-eight shape. During the process of pushing the planting board 2 up and down, the connecting rod 12, the bidirectional screw 61 and the inner wall of the hydroponic box 1 are always in a triangle, so that the planting board 2 can be raised and lowered stably.

[0029] In this embodiment, one end of the screw extends through to the outside of the hydroponic box 1 and is fixedly fitted with a handwheel 64, which facilitates the rotation of the screw.

[0030] How to use and how to work this device:

[0031] In use, a certain amount of nutrient solution is injected into the hydroponic tank 1 through the inlet 9. The rotation of the bidirectional screw 61 causes the screw sleeve 62 to move due to threaded transmission, which in turn pushes the planting plate 2 up and down via the push rod 63. This facilitates the opening and closing of the tank cover 4 and allows the planting plate 2 to be raised and planted in the cultivation trough 3 to grow the corresponding vegetables. The vegetables then grow in the hydroponic tank 1 for several weeks, nourished by the nutrient solution. Once they reach a certain size, they can be used as experimental material. Snails are placed on the vegetables, and medicine is added through the three-way tube 7. The agent is sprayed through nozzle 8. The numerous through holes 5 on the box cover 4 facilitate ventilation and agent volatilization, making it more suitable for the outdoor environment. It simulates the scenario of snails coming out to feed on crops outdoors, allowing for effective observation of the efficacy of the agent, the time of snail death, and the degree of leaf damage. The snail-killing effect of the agent is examined from both stomach poisoning and contact killing perspectives. It effectively observes and compares the efficacy of different agents, solving the problem that snails cannot be tested for efficacy indoors, and that outdoor experiments can only be conducted on cloudy or rainy days or at night, and the efficacy is difficult to observe.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
