Description

Technical Field

[0001] This invention relates to the technical field of leaf moisture content testing, and more particularly to a device and method for detecting the moisture content of poisoned mulberry leaves. Background Technology

[0002] The water content of plant leaves is usually tested by measuring the water content of wet leaves and dry leaves. In the silkworm toxicity test, it is necessary to maintain the water content of mulberry leaves in order to protect the freshness of the mulberry leaves, reduce the frequency of replacement, and help improve the reliability and operational efficiency of the silkworm toxicity experiment.

[0003] There are various effective methods for storing mulberry leaves, and different methods will ultimately affect the moisture content of the mulberry leaves after storage. In order to achieve the above effects, different storage methods need to be tested before a suitable mulberry leaf storage method can be selected. The moisture content of mulberry leaves can be tested. A commonly used method is the drying and dehydration method to test the moisture content of the leaves. In the operation, the leaves need to be heated at high temperature to evaporate the water. Then the dried leaves are taken out, cooled and weighed, and then the moisture content resulting from different storage methods can be calculated.

[0004] After the blades are dried at high temperature, they need to be removed by personnel and placed in a dry area to cool before being weighed. Since the blades are relatively fragile after drying, personnel may cause damage to the blades when moving them, which will affect the final test results. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device for detecting the moisture content of contaminated mulberry leaves to solve the problem of easy damage when drying leaves are handled and cooled.

[0006] Based on the technical problems existing in the background art, the present invention proposes a device for detecting the moisture content of poisoned mulberry leaves, including a base and a rotating plate that rotates on the base. A first outer shell and a second outer shell are respectively rotatably installed on both sides of the base to form a clamshell structure. When the first outer shell and the second outer shell are closed, a cavity can be formed. The rotating plate divides the cavity into a drying cavity and a cooling cavity.

[0007] Preferably, a side plate is provided on the side of the base, and two sets of side plates are located between the first outer shell and the second outer shell, and the side plates are spliced ​​with the edges of the first outer shell and the second outer shell.

[0008] Preferably, a horizontal plate is connected between the top ends of the two side plates, and the centers of the upper and lower ends of the rotating plate are rotatably connected to the center of the base and the center of the horizontal plate, respectively.

[0009] Preferably, hooks are provided on both sides of the rotating plate, and a mesh bag is hung on the rotating plate inside the drying chamber.

[0010] Preferably, the first outer casing is provided with a leakage hole communicating with the drying chamber.

[0011] Preferably, a semi-circular groove is provided on the horizontal plate, and a sliding rod is slidably installed in the groove and connected to the upper end of the rotating plate.

[0012] A method for detecting the moisture content of contaminated mulberry leaves, using the aforementioned detection equipment, includes the following steps.

[0013] S1: Open the first outer shell, place the mulberry leaves weighing A grams into the mesh bag, and close the first outer shell so that the mesh bag is in the drying chamber;

[0014] S2: After the mulberry leaves inside the equipment are dried at high temperature to evaporate the moisture, the equipment is removed;

[0015] S3: Rotate the horizontal plate to cool the mulberry leaves to room temperature in a sealed cooling chamber;

[0016] S4: Weigh the dried mulberry leaves and obtain the weight B grams. Calculate the moisture content C = (AB) / A * 100%.

[0017] Compared with existing technologies, the moisture content detection device for contaminated mulberry leaves proposed in this invention, using the above-mentioned technical solution, achieves the following technical effects:

[0018] This invention separates the cavity into a drying chamber and a cooling chamber by a partition. By rotating the partition within the cavity, the chambers on both sides of the partition can be switched, which can quickly isolate the heated and dried blades in a sealed chamber, avoiding the influence of external moisture during the cooling process. At the same time, it can avoid damage caused by handling the blades and improve the accuracy of blade weighing. Attached Figure Description

[0024] Example

[0025] Please refer to Figures 1-3 This invention proposes a device for detecting the moisture content of contaminated mulberry leaves, including a base 1 and a rotating plate 2 that rotates on the base 1. A first outer shell 3 and a second outer shell 4 are respectively rotatably installed on both sides of the base 1 to form a clamshell structure. When the first outer shell 3 and the second outer shell 4 are closed, a cavity 100 can be formed. The rotating plate 2 divides the cavity 100 into a drying cavity 101 and a cooling cavity 102.

[0026] In the above scheme, the first outer shell 3 and the second outer shell 4 are respectively installed on the two sides of the rotating plate 2 above the base 1. A drying chamber 101 can be formed between the first outer shell 3 and the rotating plate 2, and a cooling chamber 102 can be formed between the second outer shell 4 and the rotating plate 2. A cavity 100 can be formed between the first outer shell 3 and the second outer shell 4 and the base 1. The rotating plate 2 divides the cavity 100 into the drying chamber 101 and the cooling chamber 102. In use, the blades are placed in the drying chamber 101 through the net bag 5. After drying, the rotating plate 2 is rotated to place the net bag 5 in the cooling chamber 102, and the device can be directly placed outdoors for cooling. After removing the net bag 5, the blades are poured out for weighing.

[0027] In specific implementation, refer to Figure 2 The base 1 has a side plate 11 on its side. The two sets of side plates 11 are located between the first outer shell 3 and the second outer shell 4, and the side plates 11 are spliced ​​with the edges of the first outer shell 3 and the second outer shell 4.

[0028] In the above scheme, the side plate 11 provided on the side of the base 1 facilitates the installation and closure of the first outer shell 3 and the second outer shell 4, and the side plate 11 can provide a barrier effect for both sides of the rotating plate 2.

[0029] In specific implementation, refer to Figure 2 A horizontal plate 12 is connected between the top ends of the two side plates 11, and the centers of the upper and lower ends of the rotating plate 2 are rotatably connected to the centers of the base 1 and the horizontal plate 12, respectively.

[0030] In the above scheme, the horizontal plate 12 connected to the top of the two side plates 11 can provide an installation position for the rotating plate 2, which can stabilize the installation of the rotating plate 2. At the same time, the horizontal plate 12 and the side plates 11 can contact the edge of the rotating plate 2, reducing gaps.

[0031] In specific implementation, refer to Figure 3 Hooks 21 are provided on both sides of the rotating plate 2, and a net bag 5 is hung inside the drying chamber 101 of the rotating plate 2.

[0032] In the above scheme, the net bag 5 needs to be made of high temperature resistant material. The net bag 5 is hung in the drying chamber 101 of the rotating plate 2. Under the action of high temperature, the moisture in the blades of the net bag 5 is dried. Then the rotating plate 2 is rotated so that the net bag 5 is placed in the cooling chamber 102 for natural cooling.

[0033] In specific implementation, refer to Figure 1 The first outer shell 3 is provided with a leakage hole 31 that connects to the drying chamber 101. The horizontal plate 12 is provided with a semi-circular sliding groove 121. A sliding rod 13 is slidably installed in the sliding groove 121 and connected to the upper end of the rotating plate 2.

[0034] In the above scheme, the slide groove 121 is located above the drying chamber 101, which can maintain the sealing effect in the cooling chamber 102. At the same time, the slide rod 13 can control the rotating plate 2 to rotate. The maximum angle of the slide groove 121 is 180 degrees. When the slide rod 13 slides from one end to the other end on the slide groove 121, the internal rotating plate 2 can be rotated.
