[0002] Powder feeders are commonly used in aquaculture. There are many problems with existing powder feeders, and two of them are more prominent:

[0003] First, the pipeline is prone to moisture, and the powder is easy to stick to the pipe wall. The long-term accumulation of powder is prone to breeding bacteria and blocking the pipeline. Second, the current pneumatic feeders can only be used for feeding one pond, and cannot be used for feeding two or more ponds at the same time, which greatly increases the breeding cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a powder feeder, which can solve the problems that the pipeline of the powder feeder is prone to moisture and the current pneumatic feeder cannot be used for feeding two or more ponds at the same time.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A powder feeder includes a support frame, a silo and a feeding mechanism. The silo is installed on the support frame; the bottom discharge port of the silo is connected to the feeding mechanism. The bottom of the feeding mechanism is connected with a main pipeline. The other end of the main pipeline is connected with a plurality of branch pipelines. A blower is arranged on the main pipeline, and the blower agitates air to drive the powder to move out through the plurality of branch pipelines; a throwing head is arranged at the outlet of each branch pipeline. A control valve is arranged on each branch pipeline to control the air flow and isolate water vapor. The powder feeder operates under the control of an external controller.

[0007] Preferably, a stirring mechanism is arranged in the silo.

[0008] Preferably, the stirring mechanism includes a fixed rod, a first motor and a transmission rod. The fixed rod is fixed to the inner wall of the silo. The first motor is fixed on the fixed rod. One end of the transmission rod is connected to the output end of the first motor; a plurality of stirring rods are arranged on the transmission rod.

[0009] Preferably, the feeding mechanism includes a housing, a second motor and a screw conveyor. The second motor is arranged outside the housing and is connected to the screw conveyor to drive the screw conveyor to rotate.

[0010] Preferably, it further includes a water quality detection instrument, and the water quality detection instrument is electrically connected to the external controller.

Embodiment 1

[0021] By arranging multiple branch pipes 5 in the present utility model to feed powder into multiple ponds, the utilization rate of the equipment is improved. At the same time, in addition to controlling the opening and closing of the branch pipes 5, the control valve 8 also plays a role in isolating water vapor, avoiding the branch pipes 5 from being easily adhered with powder due to moisture absorption.

[0022] Such as Figure 1-2As shown in the figure, a powder feeding machine includes a support frame 1, a material bin 2 and a feeding mechanism 3. The material bin 2 is installed on the support frame 1. The bottom discharge port of the material bin 2 is connected to the feeding mechanism 3. The bottom of the feeding mechanism 3 is connected to a main pipeline 4. The other end of the main pipeline 4 is connected to multiple branch pipelines 5. A blower 6 is arranged on the main pipeline 4. The blower 6 agitates air to drive the powder to move to the multiple branch pipelines 5 for discharge. A throwing head 7 is arranged at the outlet of each branch pipeline 5. A control valve 8 is arranged on each branch pipeline 5 to control the air flow and isolate water vapor. The powder feeding machine operates under the control of an external controller.

[0023] The air inlet of the blower 6 is connected to the powder to play a role in sucking the powder and preventing the powder from backflushing into the material bin 2. The operation of the entire device is controlled by an external controller, enabling fine control operation of each component in the device.

[0024] Furthermore, a stirring mechanism 21 is arranged in the material bin 2. Further, the stirring mechanism 21 includes a fixing rod 211, a first motor 212 and a transmission rod 213. The fixing rod 211 is fixed to the inner wall of the material bin 2. The first motor 212 is fixed on the fixing rod 211. One end of the transmission rod 213 is connected to the output end of the first motor 212; multiple stirring rods 214 are arranged on the transmission rod 213.

[0025] Furthermore, the feeding mechanism 3 includes a housing 31, a second motor 32 and a threaded transmission rod 33. The second motor 32 is arranged outside the housing 31 and is connected to the threaded transmission rod 33 to drive the threaded transmission rod 33 to rotate.

[0026] Furthermore, a water quality detection instrument is also included, and the water quality detection instrument is electrically connected to the external controller.

[0027] Furthermore, the water quality detection instrument is a turbidity sensor, a conductivity sensor or a dissolved oxygen sensor.

[0028] Furthermore, the external controller is a computer or a single-chip microcomputer.

[0029] Furthermore, a vibration motor 11 is installed on the support frame 1.

[0030] The size of the silo 2 can be customized. The transmission rod 213 is a very crucial component with two functions. One is to mix the materials, and the other is to allow the powder materials to smoothly fall to the feeding port. Cooperating with the vibration motor 11, it enables the powder materials to fall into the housing 31. The threaded transmission rod 33 evenly pushes the powder materials into the main pipeline 4. Three-way or multi-way adapters are used for connecting multiple pipelines between pipelines. The control valve 8 can individually control the opening and closing of a branch pipeline 5, thereby controlling from which pipeline the powder materials exit. The control valve 8 has another function, that is, when the feeding work is completed, closing the control valve 8 to isolate water vapor and play a moisture-proof role. The powder materials can be scattered after passing through the throwing head 7, with a larger scattering area of the powder materials, making the fish eat more evenly.

[0031] Working principle:

[0032] When starting up after power-on, the feeding can be started through a mobile phone or a computer (setting the feeding duration, interval duration, and number of cycles). After receiving the feeding instruction, the controller first opens the control valve 8. After fully opening, it starts the fan 6 and the throwing head 7. After 5 seconds, it starts the first motor 212 to drive the transmission rod 213 to rotate. The powder materials are stirred by multiple stirring rods 214, and the vibration motor 11 makes the entire silo 2 vibrate, oscillating the powder materials away from the inner wall of the silo 2 and falling into the housing 31.

[0033] After 5 seconds, it starts the second motor 32 to drive the threaded transmission rod 33 to push the powder materials into the main pipeline 4. The fan 6 sucks the powder materials into the main pipeline 4 and blows them into multiple branch pipelines 5, and the throwing head 7 circularly scatters the powder materials around; when the feeding work is completed, first turn off the first motor 212, the vibration motor 11, and the second motor 32, then turn off the fan 6, and after 15 seconds, turn off the throwing head 7 and the control valve 8. Thus, the entire feeding process ends.

[0034] When the equipment is powered on, it will automatically perform water quality monitoring, collect water quality data, and report it to the background in real time. One set of equipment supports multiple water quality sensors.
