[0024] As follows, embodiments are further described with reference to the accompanying drawings.

[0025] like Figure 1~Figure 4 As shown, as a preferred embodiment 1, a vibrating screen feeding mechanism with dust removal and collection function comprises a dust cover 2 with a cover opening facing downwards arranged on the top of the vibrating screen 1, the dust cover 2 is arranged above the top screen body 101 of the vibrating screen 1 and forms a cage match with the top screen body 101, and the opening of the dust cover 2 forms a detachable fixed match with the top of the top screen body 101, a feed port 3 is arranged on one side of the dust cover 2, and an arc-shaped feed plate 4 rotatable in a vertical direction is coaxially and concentrically arranged in the feed port 3, and the rotating shaft of the arc-shaped feed plate 4 forms a reset rotation match with the feed port 3 through a torsion spring, and a sealing rubber ring 5 is arranged on the outer edge of the arc-shaped feed plate 4;

[0026] The top of the dust cover 2 is provided with an air suction port 8 , which is connected to the air suction end of an exhaust fan 10 through a ventilation hose 9 , and a dust filter bag 11 is provided at the air outlet end of the exhaust fan 10 .

[0027] In embodiment 1, a vibrating screen feeding mechanism with dust removal and collection function is provided, which is dust-removed by being arranged above the top sieve body 101 of the vibrating screen 1, and the top of the vibrating screen 1 is closed by installing a dust cover 2, and the exhaust fan 1 provides traction, so that the drug dust in the dust cover 2 is sucked out through the air suction port 8, and passes through the ventilation hose 9 and the exhaust fan 10 in sequence, and finally enters the dust filter bag 11 for collection to prevent waste. The drug-containing dust can be collected and prepared into other products, such as nutrient soil. The use of the ventilation hose 9 facilitates the installation of the dust cover 2 on the one hand, and at the same time makes the installed dust cover 2 have a certain flexibility during use;

[0028] When feeding is needed, the arc-shaped feed plate 4 is opened to expose the feed port 3, and the medicinal materials can be thrown onto the top sieve body 101 along the arc-shaped feed plate 4. Due to the action of the torsion spring, the kinetic energy is converted into elastic potential energy at this time. When feeding is completed, the traction force on the arc-shaped feed plate 4 when it is opened needs to be released, and the torsion spring converts the elastic potential energy into kinetic energy to reset the arc-shaped feed plate 4, and the arc-shaped feed plate 4 forms a sealing fit with the feed port 3 again. The sealing rubber ring 5, on the one hand, acts as a sealing member to ensure the sealing performance of the arc-shaped feed plate 4 after it is reset, and on the other hand, acts as a buffer to facilitate the rotation of the arc-shaped feed plate 4. In order to realize the rotation, there is a gap between the arc-shaped feed plate 4 and the feed port 3, and the gap is blocked by the sealing rubber ring 5, so that dust can be removed and feeding can be carried out at the same time without affecting each other.

[0029] As a preferred embodiment 2, the dust cover 2 and the arc-shaped feed plate 4 can both be made of transparent acrylic material, which can ensure the strength of use on the one hand, and facilitate the inspection of the operating conditions in the top screen body 101 on the other hand.

[0030] As a preferred embodiment 3, a receiving tray 103 is provided along the outer side of the opening of the top sieve body 101, and the receiving tray 103 is coaxial with the top sieve body 101, and a circle of upwardly protruding mounting protrusions 102 are coaxially provided on the inner side of the receiving tray 103.

[0031] Embodiment 3 provides a specific structure of the top screen body 101, the receiving plate 103 is used to install and hold the dust cover 2, and the mounting protrusion 102 is used to dock with the dust cover 2 to ensure the stability of the installation and facilitate installation.

[0032] As a preferred embodiment 4, the mounting protrusion 102 is docked with the cover opening of the dust cover 2, and the mounting protrusion 102 is embedded in the cover opening of the dust cover 2.

[0033] Embodiment 4 provides a specific docking method. As a more preferred embodiment, the cover opening of the dust cover 2 is snap-fitted with the mounting protrusion 102 to ensure the stability of the installation and facilitate installation.

[0034] As a preferred embodiment 5, a fixing plate 201 is provided along the outer side of the cover opening of the dust cover 2, and the fixing plate 201 is concentric and coaxial with the cover opening of the dust cover 2. When the installation protrusion 102 is completely embedded in the cover opening of the dust cover 2, the fixing plate 201 is located above the receiving plate 103 and forms a receiving match with the receiving plate 103. The receiving plate 103 receives and limits the fixing plate 201, thereby ensuring the stability of the installation of the dust cover 2 and facilitating the installation.

[0035] As a preferred embodiment 6, the receiving plate 103 and the fixed plate 201 are both provided with a plurality of fixing holes 6 at equal intervals around the axis, and the number and positions of the fixing holes 6 on the receiving plate 103 and the fixed plate 201 are one-to-one corresponding.

[0036] As a preferred embodiment 7, the corresponding fixing holes 6 are connected after being aligned, and the connected fixing holes 6 form a fixed limiting fit through the fixing bolts 7.

[0037] Embodiments 6 and 7 are used to make the receiving plate 103 correspond to the fixed plate 201, and are reinforced and installed by fixing bolts 7, so that the dust cover 2 as a whole forms a solid with the top sieve body 101, and at the same time, the dust cover 2 covers the top sieve body 101 to facilitate dust removal.

[0038] As a preferred embodiment 8, the arc-shaped feed plate 4 is located in a vertical direction in the initial state. At this time, the arc-shaped feed plate 4 cooperates with the side wall of the dust cover 2 to form a cylinder, which covers the top screen body 101. At this time, the torsion spring is in an energy release state. Because of the friction and extrusion cooperation between the sealing rubber ring 5 and the feed port 3, the arc-shaped feed plate 4 is restricted to the initial position, and the outer side of the arc-shaped feed plate 4 forms a sealing cooperation with the feed port 3 through the sealing rubber ring 5;

[0039] When the arc-shaped feed plate 4 is opened, the top of the arc-shaped feed plate 4 tilts outward, and a feed channel is formed on the inner side of the arc-shaped feed plate 4, and the feed channel tilts downward toward the top screen body 101, and the torsion spring is in an energy storage state, converting kinetic energy into elastic potential energy;

[0040] Once the arc-shaped feed plate 4 is released, the torsion spring turns to the energy release state, and the elastic potential energy is converted into kinetic energy, so that the arc-shaped feed plate 4 is reset, and finally gradually stops and returns to the initial state under the friction force of the sealing rubber ring 5.

[0041] As a preferred embodiment 9, the two sides of the arc-shaped feed plate 4 near the bottom form a rotational fit with the inner wall of the feed port 3 through a rotating shaft, and a torsion spring is provided on the rotating shaft and a reset rotational fit is formed through the torsion spring to ensure the reset rotation of the arc-shaped feed plate 4.

[0042] As a preferred embodiment 10, a handle 12 is provided on the outer top of the arc-shaped feed plate 4. It is convenient to rotate the arc-shaped feed plate 4, and the handle 12 is held during feeding to ensure the stability of the feed channel.

[0043] As a preferred embodiment 11, the air suction port 8 is arranged at the middle position of the top of the dust cover 2, so as to ensure the efficiency of air suction.

[0044] The working principle of this utility model:

[0045] The utility model provides a vibrating screen feeding mechanism with dust removal and collection functions, which is arranged above the top sieve body 101 of the vibrating screen 1 for dust removal, and the top of the vibrating screen 1 is closed by installing a dust cover 2, and the exhaust fan 1 provides traction, so that the medicine dust in the dust cover 2 is sucked out through the suction port 8, and passes through the ventilation hose 9 and the exhaust fan 10 in sequence, and finally enters the dust filter bag 11 for collection, so as to prevent waste, and the medicine-containing dust can be collected and prepared into other products, such as nutrient soil. The use of the ventilation hose 9 is convenient for the installation of the dust cover 2, and at the same time, the dust cover 2 after installation has certain flexibility during use;

[0046] When feeding is needed, the arc-shaped feed plate 4 is opened to expose the feed port 3, and the medicinal materials can be thrown onto the top sieve body 101 along the arc-shaped feed plate 4. Due to the action of the torsion spring, the kinetic energy is converted into elastic potential energy at this time. When feeding is completed, the traction force on the arc-shaped feed plate 4 when it is opened needs to be released, and the torsion spring converts the elastic potential energy into kinetic energy to reset the arc-shaped feed plate 4, and the arc-shaped feed plate 4 forms a sealing fit with the feed port 3 again. The sealing rubber ring 5, on the one hand, acts as a sealing member to ensure the sealing performance of the arc-shaped feed plate 4 after it is reset, and on the other hand, acts as a buffer to facilitate the rotation of the arc-shaped feed plate 4. In order to realize the rotation, there is a gap between the arc-shaped feed plate 4 and the feed port 3, and the gap is blocked by the sealing rubber ring 5, so that dust can be removed and feeding can be carried out at the same time without affecting each other.
