[0031] As Figure 1 and Figure 2 As shown in

[0032] The air suction component includes a dust suction port 41. The dust suction port 41 is placed inside the housing 1 and can adsorb the stored tobacco pests that are electrostatically attached to the inner wall of the housing 1 during the stirring and vibrating processes of the sieved tobacco leaves, improving the accuracy of finding the stored tobacco pests in the sieved tobacco leaves and the accuracy of judging the pest damage in the overall tobacco leaves. The setting of the air suction component can also adsorb the impurities generated during the vibration of the sieved tobacco leaves, preventing the staff from inhaling a large amount of impurities when taking the sieved tobacco leaves after vibration, ensuring the physical health of the staff, and facilitating the subsequent cleaning of the inside of the housing 1. At the same time, it avoids impurities from adhering to the screen 23, further improving the sieving quality of the electric sieving device for the sieved tobacco leaves.

[0033] The electric sieving device provided in this embodiment, by setting a sieving component 2 and a stirring member 3, the stirring member 3 is used to stir the sieved tobacco leaves to make the sieved tobacco leaves spread out fully, enabling all the stored tobacco pests in each part of the sieved tobacco leaves to be exposed, avoiding the incomplete search situation when manually searching for stored tobacco pests. The vibrating member 21 drives the screen 23 to vibrate through the guide rail 22, enabling the exposed stored tobacco pests in the sieved tobacco leaves to fall off. Through the cooperation of the stirring member 3 and the sieving component 2, a large number of the stored tobacco pests in the sieved tobacco leaves can be made to fall off. By setting the air suction component, it can adsorb the small-volume stored tobacco pests electrostatically attached to the inner wall of the housing 1, improving the accuracy of finding the stored tobacco pests in the sieved tobacco leaves and the accuracy of the staff's judgment of the pest damage degree in the overall tobacco leaves, and thus more accurately judging the economic losses.

[0034] In this embodiment, the air suction component is arranged at the lower inner part of the housing 1, so that the sieved tobacco leaves have more space for stirring.

[0035] In this embodiment, after using the sieving component 2 and the stirring member 3 to vibrate and stir the sieved tobacco leaves, the air suction component is then started to adsorb the stored tobacco pests and impurities inside the housing 1, making the operation of the electric sieving device more reasonable.

[0036] In this embodiment, there is a gap between the stirring rod 31 and the sieving component 2, which can enable the sieved tobacco leaves to bury the stirring rod 31, further improving the stirring effect of the stirring member 3 on the sieved tobacco leaves and making the sieved tobacco leaves looser.

[0037] In this embodiment, the housing 1 is provided with a movable door panel 8 for closing the internal space of the housing 1, making the housing 1 have an open state and a closed state. When the electric sieving device stops working, the staff can open the movable door panel 8 to take out the sieved tobacco leaves inside the housing 1. The movable door panel 8 is connected to the housing 1 through a hinge.

[0038] In this embodiment, the stirring member 3 further includes a rotating motor 32, wherein the output end of the rotating motor 32 is connected to the stirring rod 31, and the rotating motor 32 drives the stirring member 3 to rotate, so as to stir and screen the tobacco leaves. The rotating motor 32 can be selected from one of a DC motor, an AC motor, a synchronous motor or an asynchronous motor.

[0039] In this embodiment, the vibrating member 21 can be selected as a vibrating motor, which can be selected from one of a DC motor, an AC motor, a synchronous motor or an asynchronous motor. During actual assembly, the main body of the vibrating motor can be placed outside the housing 1, and a through hole is provided on the housing 1, and the output end of the vibrating motor passes through the through hole and is placed inside the housing 1. In this way, the occupied space of the vibrating member 21 in the housing 1 can be reduced, and the design of the electric screening device can be made more reasonable.

[0040] In this embodiment, the air suction assembly further includes a suction pump and a storage bag. The air suction pump communicates with the dust suction port 41 and the storage bag, so that the adsorbed impurities can be directly stored in the storage bag. The air suction pump and the storage bag are placed at the bottom of the housing 1, so that the electric screening device can be miniaturized. Regarding the structure and operating principle of the air suction assembly, reference can be made to existing air suction devices, which are not the key protection content of the present invention and will not be elaborated here.

[0041] In this embodiment, a plurality of screening assemblies 2 are provided, and the plurality of screening assemblies 2 are arranged in sequence along the height direction inside the housing 1, and the mesh numbers of the screen meshes 23 in the plurality of screening assemblies 2 increase sequentially from top to bottom. In this way, the screening of the tobacco leaves can be realized step by step, and the insect states of different sizes of stored tobacco pests can be screened out, improving the accuracy of the staff to judge the degree of insect damage of the overall tobacco leaves. Among them, the mesh numbers of the different-layer screen meshes 23 are 10 meshes and 20 meshes from top to bottom in sequence.

[0042] In this embodiment, the electric screening device further includes a buffer plate 5 and an elastic member. There are two buffer plates 5, and the two buffer plates 5 are rotatably arranged on both sides of the opening, and the elastic member is connected between the buffer plate 5 and the inner wall of the housing 1. When no screened tobacco leaves are placed on the buffer plate 5, the two buffer plates 5 close the opening under the action of the elastic force of the elastic member. As the staff puts the screened tobacco leaves into the housing 1, the two mutually opened buffer plates 5 can immediately change to the closed state, preventing the floating impurities generated when the screened tobacco leaves fall on the screen mesh 23 from floating to the external environment through the opening, and further ensuring the physical safety of the staff. In this embodiment, the elastic member includes a bracket and a spring. The bracket is vertically and fixedly connected to the inner wall of the housing 1, one end of the spring is vertically and fixedly connected to the bracket, and the other end is connected to the buffer plate 5.

[0043] In this embodiment, as Figure 1 and Figure 3As shown in the figure, the stirring rod 31 includes a central body 311 and a plurality of stirring blades 312. The plurality of stirring blades 312 are arranged at intervals on the outer periphery of the central body 311. By providing the stirring blades 312, the stirring rod 31 can disperse the screened tobacco leaves in the housing 1 faster, and at the same time ensure that the screened tobacco leaves after stirring are looser, so as to screen out the stored tobacco pests in the screened tobacco leaves to the greatest extent. Preferably, the stirring blade 312 and the central body 311 can be detachably connected, so that it is convenient for the staff to maintain and replace the stirring blade 312 regularly, and ensure the stirring effect of the stirring member 3.

[0044] In this embodiment, the screen 23 and the guide rail 22 can be detachably connected. On the one hand, it is convenient for the staff to remove the screen 23 from the guide rail 22 at any time, so as to clean the grid of the screen 23 regularly, ensure that the stored tobacco pests in the screened tobacco leaves can fall from the grid of the screen 23, and the electric screening device can be used normally. On the other hand, it is also convenient for the staff to clean the inside of the housing 1 and ensure the cleanliness of the inside of the housing 1.

[0045] Preferably, as Figure 1 and Figure 4 shown in the figure, the electric screening device further includes a dust-proof cover 6. The dust-proof cover 6 can selectively cover the opening. When the screened tobacco leaves are placed in the housing 1 and the stirring member 3 and the screening assembly 2 are working, the staff can use the dust-proof cover 6 to cover the opening, so as to further prevent the impurities in the screened tobacco leaves from floating into the external environment on the basis of the buffer plate 5, and further protect the physical safety of the staff. In this embodiment, the dust-proof cover 6 can be designed as an arch, a circle, a rectangle, and no specific limitation is made here. Preferably, the dust-proof cover 6 is made of transparent plastic material, which is not only light but also convenient for the staff to observe the stirring situation of the screened tobacco leaves in the housing 1 in real time. Of course, the dust-proof cover 6 can also be made of other materials, and no specific limitation is made here. In this embodiment, the dust-proof cover 6 can be connected to the housing 1 by a clamping method or by a bolt fastening device. Regarding the connection method of the dust-proof cover 6 and the housing 1, no specific limitation is made here.

[0046] In this embodiment, the electric screening device further includes a storage member 7. The storage member 7 is placed below the screening assembly 2, so that the stored tobacco pests screened out from the screened tobacco leaves can fall into the storage member 7, and it is not necessary for the staff to sort out the stored tobacco pests separately, making the design of the electric screening device more reasonable. The storage member 7 can be a drawer or a storage bag.

[0047] In this embodiment, the electric screening device further includes universal wheels, which are arranged at the bottom of the housing 1, facilitating the staff to move the electric screening device according to the work needs and making the work of the staff more labor-saving. At the same time, the universal wheels have a locking function. When the electric screening device is operating, the universal wheels can be adjusted to the locked state to prevent the electric screening device from moving due to vibration during operation. Regarding the universal wheels with a locking function, their specific structure and working principle can be designed with reference to the existing technology and are not the key protection content of the present utility model, so they will not be elaborated here. Preferably, the electric screening device further includes a handle, which is placed on the outer wall of the housing 1. The handle is provided to facilitate the staff to carry or push the electric screening device and make the work of the staff more labor-saving.

[0048] Obviously, the above embodiments of the present utility model are only examples for clearly illustrating the present utility model and are not limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included in the protection scope of the claims of the present utility model.
