[0015] (1) The discharging device capable of preventing grain backflow is driven by a driving motor to drive the driving disc and the transmission rod to rotate synchronously. When the transmission rod rotates, the transmission block slides to the inner surface of the arc groove, thereby causing the rotating disc, the rotating rod and the discharging plate to rotate synchronously by 60°. When the transmission block slides out of the arc groove, the surface of the driving disc fits with the surface of the arc plate, thereby preventing the rotating disc, the rotating rod and the discharging plate from rotating. The discharging plate is driven to rotate intermittently, so that the grain falling between the multiple groups of discharging plates in the storage box is driven by the discharging plate to rotate to the bottom of the diverter box and slide out through the discharging pipe, thereby realizing the quantitative discharging operation of the grain. The quantitative discharging operation of the grain is realized by the driving motor, and the grain discharging rate is adjusted by adjusting the rotation rate of the driving motor. In addition, since the outer side of the discharging plate fits and slides with the inner surface of the diverter box, the grain backflow can be prevented.

By providing a dust-proof mechanism, the air circulation inside the storage box is maintained. At the same time, the dust generated when the grain is stored is prevented from being scattered to the outside and affecting the surrounding personnel or the environment.

[0027] The discharging assembly 31 comprises a shunt box 311 installed at the bottom of the storage box 1, a discharging pipe is installed at the bottom of the shunt box 311, a rotating rod 312 is rotatably connected inside the shunt box 311, the rotating rod 312 rotates inside the control box 321, a plurality of discharging plates 313 are fixedly connected to the surface of the rotating rod 312, the outer side of the discharging plate 313 is in contact with the inner wall of the shunt box 311, one side of the discharging plate 313 is slidably connected to the inner surface of the shunt box 311, one end of the rotating rod 312 is fixedly connected to a rotating disk 314, a plurality of arc grooves 315 are provided on the surface of the rotating disk 314, and an arc plate 316 is fixedly connected to the surface of the rotating rod 312;

[0028] The drive assembly 32 is arranged at the front side of the shunt box 311 and is used to drive the discharge plate 313 to rotate. The drive assembly 32 includes a control box 321 installed at the front side of the shunt box 311. The front side of the control box 321 is fixedly connected with a drive motor 322. The drive motor 322 is a three-phase asynchronous motor. The drive motor 322 is connected to an external circuit through wires. One end of the output shaft of the drive motor 322 is fixedly connected with a drive disk 323 through a coupling. The surface of the drive disk 323 is slidably connected to the surface of the arc plate 316. One side of the drive disk 323 rotates the rotating disk 314 through a transmission assembly 4. The transmission assembly 4 includes a transmission rod 41 installed on one side of the drive disk 323. One end of the transmission rod 41 is fixedly connected with a transmission block 42. The surface of the transmission block 42 is slidably connected to the inner surface of the arc groove 315. The drive motor 322 drives the drive disk 323 and the transmission rod 41 to rotate synchronously. When the transmission rod 41 rotates, The transmission block 42 slides to the inner surface of the arc groove 315, thereby making the rotating disk 314, the rotating rod 312 and the discharge plate 313 rotate synchronously by 60°.

[0029] Embodiment 2

[0030] The main difference from the first embodiment is:

[0031] A discharging device capable of preventing grain from flowing back, wherein the dustproof mechanism 2 comprises a dustproof box 21 installed on the top of a storage box 1, a driving motor 22 is fixedly connected to the inner wall of the dustproof box 21, the driving motor 22 is connected to an external circuit through an electric wire, a fan 23 is fixedly connected to one end of an output shaft of the driving motor 22, an exhaust duct 24 is installed on the front side of the dustproof box 21, the rear side of the dustproof box 21 is fixedly connected to the top of the storage box 1 through a ventilation duct 25, an adsorption assembly 26 is arranged inside the dustproof box 21, the adsorption assembly 26 comprises a mounting plate 261 installed on the inner wall of the dustproof box 21, an adsorption layer 262 is slidably connected to the inner surface of the mounting plate 261, the adsorption layer 262 is a dust filter, and the adsorption layer 262 is fixedly connected to the top of the storage box 1 through a fixing bolt Installed inside the dustproof box 21, the right side of the storage box 1 is fixedly connected with a feed pipe 5, the feed pipe 5 is connected to an external grain pumping machine, and the bottom of the storage box 1 is fixedly connected with multiple groups of support legs 6. By starting the driving motor 22 to drive the fan 23 to rotate, the dust generated when the grain is pumped is extracted through the ventilation pipe 25, and the dust is adsorbed by the adsorption layer 262, and finally the gas is discharged through the exhaust pipe 24 to avoid dust scattering. By providing a dustproof mechanism 2, the air circulation inside the storage box 1 is maintained. At the same time, it is prevented that dust is generated when the grain is stored and scattered to the outside, causing an impact on the surrounding personnel or the environment. At the same time, the contents not described in detail in this specification belong to the existing technology well known to technical personnel in this field.

[0032] During operation, when the grain is introduced into the storage box 1 through the external grain pumping machine and the feed pipe 5, at this time, the fan 23 is driven to rotate by starting the drive motor 22, and the dust generated when the grain is pumped is extracted through the ventilation pipe 25, and the dust is adsorbed by the adsorption layer 262, and finally the gas is discharged through the exhaust pipe 24 to avoid dust scattering. When the grain needs to be processed, the drive motor 322 is started to drive the drive disk 323 and the transmission rod 41 to rotate synchronously. When the transmission rod 41 rotates, the transmission block 42 slides to the inner surface of the arc groove 315, so that the rotating disk 314, the rotating rod 312 and the discharge plate 313 rotate synchronously by 60°. When the transmission block After 42 slides out of the arc groove 315, the surface of the driving disk 323 is in contact with the surface of the arc plate 316, so as to prevent the rotating disk 314, the rotating rod 312 and the discharge plate 313 from rotating. By driving the discharge plate 313 to rotate intermittently, the grain that falls into the multiple groups of discharge plates 313 in the storage box 1 is driven by the discharge plate 313 to rotate to the bottom of the diverter box 311 and slide out through the discharge pipe, so as to realize the quantitative discharge operation of the grain. The grain discharge rate can be adjusted by adjusting the rotation speed of the driving motor 322. In addition, since the outer side of the discharge plate 313 is in contact with and slides with the inner surface of the diverter box 311, the backflow of grain can be prevented.
