Technical Field

[0001] The utility model belongs to the technical field of animal husbandry feeding equipment, in particular to a novel material feeding metering device. Background Art

[0002] As we all know, the existing intelligent feeder adopts an auger-type feeding structure, that is, the auger is driven to rotate by a motor to achieve auger feeding. The feeding amount detection often uses an encoder to control the motor speed, and the feeding amount at a certain time under the motor speed is calculated based on the motor speed, that is, the feeding metering of the intelligent feeder is achieved through time and motor speed.

[0003] However, in the actual operation process, because the auger feeding structure is stopped, residual materials are easy to be generated in the auger bin. These residual materials gradually accumulate, which will lead to inaccurate feeding metering values, resulting in the problem of either too much or too little feed.

[0004] Therefore, how to design a new type of material metering device to solve the problem of precise material control has become a key research topic in the existing technical field. Utility Model Content

Because the airlock impeller has a single-grid feeding structure, and the feeding amount of each single grid is fixed, there is no problem of excess material in the auger structure in the prior art; at the same time, through the design of the detection device, the number of revolutions of the airlock impeller can be detected, that is, the feeding amount of the intelligent feeder can be calculated by the number of revolutions and the feeding amount of each grid. Therefore, compared with the prior art, the present application can realize the precise control of the feeding amount of the intelligent feeder, and is worthy of promotion.

[0021] It should be noted that the control system may include a control loop including a PLC controller, a display screen, a control algorithm and an actuator, etc., and the automatic control of the intelligent feeder is realized through the control system. In this application, the number of turns detected by the detection device is sent to the PLC controller, and the PLC controller calculates the feeding amount according to the internal algorithm, and the calculated feeding amount is automatically compared with the preset feeding amount. When the detected feeding amount reaches the preset feeding amount value, the PLC controller will control the driving device 5 to stop working through the actuator. The above-mentioned automatic control process of the intelligent feeder belongs to the common automatic control system in the prior art and will not be described in detail.

[0022] Compared with the prior art, the present application has the following effects: when in use, the feed enters the airlock housing 1 through the feed inlet, and the driving device 4 drives the airlock impeller 6 to rotate, thereby realizing the rotation and feeding of the airlock impeller 6. Because the structure of the airlock impeller 6 is single-grid feeding, and the feeding amount of each single grid is fixed, there is no problem of excess material in the auger structure in the prior art; at the same time, through the design of the detection device 5, the number of rotations of the airlock impeller 6 can be detected, that is, the feeding amount of the intelligent feeder can be calculated by the number of rotations and the feeding amount of each grid. Therefore, compared with the prior art, the present application can realize the precise control of the feeding amount of the intelligent feeder, which is worthy of promotion.

The Hall sensor 52 is arranged in the cavity between the air lock housing 6 and the rear end cover 3. When the driving device drives the air lock impeller 6 to rotate, the Hall sensor 52 sends the generated pulse signal to the control system. The Hall sensor 52 here can also be replaced by a reed switch. It should be noted that the detection device 5 can also include a photoelectric sensor and a baffle. The baffle is arranged on the air lock impeller 6. Whenever the baffle passes through the photoelectric sensor, the photoelectric sensor will send a signal to the control system, so that the number of rotations of the air lock impeller 6 can also be detected. The reason why the present application uses the structure of the magnet 51 and the Hall sensor 52 is that the structure has low cost, high sensitivity, is not easily disturbed by the external environment, and has better reliability.
