[0003] The fish feed drying devices in the prior art mostly perform a blow-drying process during drying. During this process, the fish feed accumulated at the bottom is prone to incomplete drying. Moreover, after drying, the feed needs to be collected manually, which makes the device inconvenient to use. Therefore, it is necessary to propose a drying device for fish feed production to solve the above problems. Summary of the Invention

[0006] By adopting the above technical solution, the box door is opened and the fish feed is poured into the two material placement trays, and the drying component dries it. After the fish feed is completely dried, the electric push rod is driven, and the connecting plate drives the two rings to move upward, so that the rack moves upward, which can drive each gear to rotate, and the rotating shaft drives the fan-shaped plate to flip, thereby placing the fish feed down and automatically collecting it, which greatly saves labor.

[0007] The present invention is further configured as follows: a plurality of guide rods are installed circumferentially between the upper and lower material placement plates, and a guide block slidably adapted to the guide rods is installed on the inner side of the connecting plate.

[0008] By adopting the above technical solution, the cooperation between the guide rod and the guide block makes the lifting and lowering of the upper and lower rings more stable.

[0009] The present invention is further configured as follows: the driving member includes a motor installed on the outer wall of the drying chamber, the output end of the motor is installed with a first main bevel gear, the inner cavity of the drying chamber is vertically installed with a rotating rod, the rotating rod is installed with a driving gear and a first slave bevel gear adapted to the first main bevel gear, and a gear ring adapted to the driving gear is connected between the multiple connecting plates.

[0010] By adopting the above technical solution, the motor drives the first main bevel gear to rotate, pushing the first slave bevel gear to rotate, causing the rotating rod to rotate, driving the driving gear to rotate, and rotating it through engagement with the gear ring, thereby driving the two material placement plates to rotate simultaneously, making it easier to rotate and dry the fish feed.

[0011] The present invention is further configured as follows: the driving member also includes a first synchronous belt structure installed between the sleeve and the rotating rod, a plurality of stirring rods are arranged on the circumference of the sleeve, a plurality of stirring blades are arranged on the stirring rod, a second slave bevel gear is installed at one end of the stirring rod extending into the sleeve, and a second main bevel gear adapted to the second slave bevel gear is installed on the column.

[0012] By adopting the above technical solution, when the rotating rod rotates, the first synchronous belt structure pushes the sleeve to rotate, so that the external stirring rod is reversed relative to the material placement plate, and through the engagement of the second slave bevel gear and the second main bevel gear, the stirring rod rotates at the same time, causing the stirring blade to rotate, stirring the fish feed, and achieving a better drying effect.

[0013] The present invention is further configured as follows: the drying component includes an arc-shaped frame arranged in the inner cavity of the drying chamber and a screw structure for driving the arc-shaped frame to rise and fall; a plurality of air outlet tubes are arranged on the inner side of the arc-shaped frame; a hot air blower is installed at the upper end of the drying chamber; and a first pipe connected to the arc-shaped frame is installed at the output end of the hot air blower.

[0016] By adopting the above technical solution, the reciprocating screw is driven to rotate by the second synchronous belt structure while the rotating rod rotates. Under the guidance of the vertical rod, the arc frame is lifted up and down. The second synchronous belt structure and the first synchronous belt structure are both composed of two synchronous wheels and a synchronous belt. When one synchronous wheel rotates, the synchronous belt drives the other synchronous wheel to rotate at the same time. This is common knowledge.

[0017] The present invention is further configured as follows: the drying component also includes a turntable rotatably arranged on the upper end surface of the drying chamber, the lower end of the turntable is provided with an annular air duct and a connecting rod connecting the annular air duct, the outer end of the rotating shaft is rotatably provided with a ring, and the upper circumference of the annular air duct is provided with a plurality of auxiliary pipes connecting the ring and the rotating shaft, the inner cavity of the fan-shaped plate is configured to be hollow, and a second pipe is connected between the output end of the hot air blower and the annular air duct.

[0018] By adopting the above technical solution, the rotation of the material placement plate is made smoother by the arrangement of the turntable and the connecting rod. Air is blown into the annular air duct from the second pipe, and then enters the collar through the auxiliary pipe and is introduced into the fan-shaped plate. The hot air flow can preheat the bottom of the fan-shaped plate, so that the fish feed at the lower end of the stack will also be heated, thereby achieving uniform drying treatment.

[0024] By adopting the above technical solution, the dried fish feed falls into the discharge hopper and is then discharged from the discharge port through the discharge slope, making it convenient to collect and greatly saving labor.

[0025] The beneficial effects of the present invention are:

[0026] 1. The present invention drives the electric push rod, and the connecting plate drives the two rings to move upward, so that the rack moves upward, which can push each gear to rotate, and the rotating shaft drives the fan-shaped plate to flip, so that the fish feed is lowered and falls into the hopper, and then discharged from the discharge port through the discharge slope, so that it is convenient to collect it and greatly saves labor.

[0027] 2. The present invention drives the first main bevel gear to rotate through a motor, which pushes the first follower bevel gear to rotate, causing the rotating rod to rotate, driving the driving gear to rotate. By engaging with the gear ring, it rotates, thereby driving the two material placement trays to rotate simultaneously. The hot air blower blows out hot air and sends it to the curved frame through the first pipe. The hot air is sprayed from the air outlet to dry the fish feed. The curved frame is driven up and down by the screw structure, greatly accelerating the drying operation of the fish feed.

[0028] 3. In the present invention, when the rotating rod rotates, the first synchronous belt structure drives the sleeve to rotate, causing the external stirring rod to reverse relative to the material placement plate. The second secondary bevel gear engages with the second primary bevel gear, causing the stirring rod to rotate simultaneously, causing the stirring blade to rotate, stirring the fish feed. Air is blown into the annular air duct through the second pipe, then enters the sleeve through the auxiliary pipe and is guided into the fan-shaped plate. The hot air flow can preheat the bottom of the fan-shaped plate, so that the fish feed at the lower end of the stack is also heated, thereby achieving uniform drying.
