The batch feeder is a mechanical device which can throw feed into a target water body within a specified time according to user settings, and a typical batch feeder usually consists of a machine box, a hopper, a blanking device, a material throwing device and an electronic control device. Fig. 1 to 3 are schematic structural views of three conventional batch feeders, respectively.

Referring to fig. 1, the feeder includes a hopper 1a, a case 3a, a discharging device 4a, a pipeline 5a, a throwing device 6a and an electronic control device, wherein the hopper 1a has a large enough volume, and can be filled with one to several bags of feed at a time, and the bottom of the hopper 1a has a certain inclination 2a, so that the feed can automatically slide down and enter the discharging device 4a through a hopper outlet at the bottom. The discharging device 4a is arranged between the hopper 1a and the throwing device 6a, and the fodder at the outlet of the hopper is uniformly transmitted to the throwing device 6a through a vibration or rotating mechanism. The material throwing device 6a comprises a material throwing disc 7a, a motor 8a and a guide cover 9a, and the material throwing device 6a can throw feed at a certain angle to the right front through the rotation of the motor 9 a. The electronic control device is used for controlling the opening and closing of the feeder and adjusting the vibration intensity or the rotation speed of the blanking device 4a so as to control the blanking speed.

The material throwing device can also adopt a blower, and the blower generates strong air flow to blow out the feed particles conveyed by the material discharging device at high speed through an air pipe. Referring to fig. 2, the feeder includes a base 1b, a hopper 2b, a blower 3b, a blanking device 4b, a first pipe 5b and a second pipe 6b, the feeder is not applicable to a material throwing disc, and the blower 3b is used for conveying high-speed air flow in the first pipe 5b, so that the feed falling from the blanking device 4b is blown out at high speed through the second pipe 6b, thereby achieving the purpose of feeding. The second conduit 6b may also be mounted distally to deliver feed to a greater distance.

The feeding management is the link with the highest labor capacity and cost in the aquaculture process, and the feed cost of typical aquaculture varieties accounts for nearly 70% of the total aquaculture cost, so that the feeding management is good, and the accurate feeding has great significance in saving the aquaculture cost and improving the aquaculture efficiency.

In the prior art, the feed feeding amount is controlled by setting the timing time length, and the feeding process of the feeder can be continued for a long enough time, so that the feeding of a sufficient amount of feed is ensured. The length of the feeding time can be realized by setting the timing time of the electronic control device. An operation panel is generally provided on the electronic control device, and can be used for setting the blanking speed. Taking the vibration feeding mode as an example, the vibration intensity of the vibrator can be adjusted to set the blanking speed, and the larger the vibration intensity is, the faster the blanking is. The feeding time indicates the duration of one feeding action, and the longer the feeding time is, the longer the duration of one feeding action is, and the more the fed material is. The feeding interval represents the time between two feeding actions, and the shorter the feeding interval is, the more frequent the feeding is, and the larger the continuous discharging amount is in a period. The timing duration indicates how long the batch feeder is operated to stop batch feeding after being started. When the vibration intensity, the feeding time and the feeding interval are determined, the longer the timing time length is, the longer the continuous feeding time is, and the more feed is fed.

The device can realize that when the batch feeder finishes the batch feeding of the timing duration, the batch feeding action is automatically stopped, and the purpose of saving the feed is achieved. However, in order to ensure sufficient feed delivery, the timing time may exceed the actual required working time, so that the feeder delivers too much feed, resulting in waste of feed. Meanwhile, because the feed amount in the hopper cannot be known, if the feed amount in the hopper is less than the expected feed amount, the phenomenon of idling of the feeder can occur in the feeding process, and no feed is actually fed. Although the set timing period is completed, a sufficient amount of feed is not fed, which adversely affects the actual cultivation effect. Moreover, because the batch feeder is still feeding when no feed is in the hopper, not only the equipment is damaged, but also the electric quantity is wasted.

On the other hand, because the vibration unloader that uses always requires highly to manufacturing process, actual device hardly accomplishes vibration intensity unanimity, therefore different devices are under the same batch intensity, batch duration and batch interval setting, and the speed of actual batch can have huge difference, and the batch quantity error is too big through batch time estimation, therefore can't satisfy the measurement demand in the production process.

In the prior art, an infrared technology is also adopted to realize material-free shutdown, referring to fig. 3, in order to avoid material-free time rotation in the material accommodating hopper 1c, two ends of an infrared detection device 2c which is additionally arranged at the outlet of the bottom of the material accommodating hopper 1c are respectively provided with an infrared light emitting module 3c and an infrared light receiving module 4c. When the fodder is contained in the hopper 1c, the infrared light emitted by the infrared light emitting module 3c is blocked by the fodder and cannot be received by the infrared light receiving module 4c. When no feed passes through the bottom outlet in the hopper 1c, the infrared light emitted from the infrared light emitting module 3c is received by the infrared light receiving module 4c at the other end. The infrared detection device 2c outputs different voltage values according to whether the receiving end can receive infrared light. The electronic control device 5c in the feeder is connected with the infrared detection device 2c through a connecting wire 6c, and the electronic control device 5c reads the voltage value output by the infrared detection device 2c through an AD sampling interface, so that whether the feed exists in the feed hopper 1c is judged. When the feed hopper 1c is not filled with feed, the feeder automatically stops feeding and throwing.

The device has the advantages that whether the feed exists in the hopper can be judged, when the feed does not exist in the hopper, the feeding and throwing operations are automatically stopped, the idling of equipment is avoided, and the effect of saving electricity is achieved. However, since it is only possible to determine whether or not there is feed and the remaining amount of feed cannot be known, when there is no feed in the hopper, the user cannot be informed of the replenishment of feed in time, and the desired feeding task cannot be completed. In the installation mode, the electronic control device is arranged above or beside the hopper, the infrared detection device is arranged at the outlet of the bottom of the hopper, and the infrared detection device are connected by a wire with a certain length, so that the infrared detection device has certain complexity. Moreover, the device can only realize automatic stop without materials, and can not measure the total feeding amount, so that the accurate management of the cultivation process can not be realized.

In order to realize weighing management of the batch feeder, manufacturers try to directly put a flat scale under the batch feeder, and then read weighing information of the scale through a data line. Because the batch feeder is usually installed on a simple batch feeder table built by materials such as a stick, an iron pipe and the like in an actual application scene, the base of the batch feeder table is very uneven, a common platform scale cannot be used, the working environment of the batch feeder is in a strong vibration environment for a long time, the weighing error of the common platform scale is continuously enlarged after the common platform scale is used for a period of time, the cost of the platform scale is high, and the unit price even exceeds that of the batch feeder per se, so the scheme is not applied to actual production.

In view of this, the present utility model provides a weighing foot that can be used to mount to the bottom of a batch feeder, and fig. 4-11 illustrate a preferred embodiment of the weighing foot provided by the present utility model.

Referring to fig. 12 and 13, the feeder 200 is provided with an electronic control device 210, and the electronic control device 210 is configured to measure the feed allowance in the feeder 200 according to the load cell 140.

Specifically, the feeder 200 includes a bin 220, a discharging device (not shown in the drawing), a throwing device (not shown in the drawing), a shortage detecting device (not shown in the drawing), and an electronic control device 210. The material throwing device and the material bin 220 may be assembled together, or the material throwing device and the material bin 220 may be separated into two independent components, and then assembled together when in use, the overall structure of the assembled feeder 200 is still the same as that in fig. 12, i.e. the material bin 220 is mounted above the material discharging device, so that the feed can enter the material throwing device under the action of gravity. The electronic control device 210 includes a control panel, which is an electronic circuit that can be used to control the opening and closing of the blanking device and the throwing device. The control panel is usually disposed at the top of the batch feeder 200, and the bottom of the batch feeder 200 is provided with a batch throwing port 230.

Referring to fig. 4 and 13, the load cell 140 in the weighing leg 100 is electrically connected to the electronic control device 210, and the feeder connector 110 in the weighing leg 100 is installed at the bottom of the feeder 200 downward.

Specifically, the bottom of the feeder 200 is formed with a bottom plane, the feeder connector 110 in the weighing leg 100 can be fixed to the bottom of the feeder 200 by screws, and the signal line 143 of the weighing sensor 140 passes out through the sensor outlet 116 on the weighing leg 100 and is connected to the electronic control device 210 on the feeder 200. The weighing feet 100 can measure the load on the feet and transmit data to the electronic control unit 210, with the final result being calculated synthetically by the electronic control unit 210.

Alternatively, referring to fig. 13, in the present embodiment, a plurality of weighing feet 100 are provided, and a plurality of weighing feet 100 are provided at intervals along the circumferential direction of the feeder 200, for example, referring to fig. 13, four weighing feet 100 are provided, and the four weighing feet 100 are provided at four corners of the bottom of the feeder 200, respectively.

When the weighing feet 100 are provided with a plurality of weighing sensors 140, each weighing foot 100 can be provided with a weighing sensor 140, so that the measurement accuracy is higher; the weighing cell 140 may be mounted to a part of the plurality of weighing legs 100, and the weighing cell 140 may be not mounted to the rest. For example, in the case where the measurement accuracy is not required, one or both of the weighing cells 140 on the four weighing feet 100 may be detached.

The electronic control device 210 is a control circuit with a built-in microprocessor, alternatively, in this embodiment, the electronic control device 210 includes a microprocessor and a nonvolatile memory.

Specifically, the electronic control device 210 has signal interfaces connected to the blanking device, the throwing device, the shortage detection device, and the weighing leg 100. The electronic control unit 210 comprises a programmable microprocessor which can control the start and stop of the blanking unit and the throwing unit by instructions and read the measurement result of the shortage detection unit, and detect whether the feed is present in the current bin 220 by the shortage detection unit. Wherein, lack material detection device can be for setting up the infrared geminate transistors in the feed bin 220 bottom, and the signal that infrared geminate transistors's emitter sent blocks the fodder when there is fodder in the feed bin 220 to whether there is surplus fodder in the detection feed bin.

At the same time, the microprocessor has a timing function to measure the interval time between the starting and stopping of the blanking device and the throwing device

The electronic control unit 210 includes a nonvolatile memory capable of storing data permanently, and the data of the weight of the feeder 200 and the measurement data of the load cell 140 at the time of the last shortage are stored in the memory.

The electronic control unit 210 includes a man-machine interface (i.e., control panel) that can input the current feed weight and can store the input results in a built-in memory.

Since the feeder 200 can generate strong vibration during feeding, and the accurate weight cannot be obtained by directly reading the sensor data during working, optionally, in this embodiment, the electronic control device 210 is configured to obtain the measured value of the weighing sensor 140 after stopping the blanking device and the throwing device for a first preset period of time.

Specifically, the electronic control device 210 may automatically stop the discharging device and the throwing device when weighing, and restart after the weighing is completed. The workflow when the feeder device 1000 needs to be weighed may be as follows: 1. stopping the blanking device and the throwing device, and waiting for a plurality of seconds (namely, a first preset time period) to stop shaking the feeder 200; 2. continuously reading data of the weighing sensor 140, and averaging the results to further eliminate interference of factors such as shaking; 3. adding up the data of all weighing sensors 140 to obtain the total weight, and subtracting the dead weight of the batch feeder 200 stored in the nonvolatile memory to obtain the weight of the residual feed; restarting the blanking device and the throwing device to continue the feeding process.

Optionally, in this embodiment, the electronic control device 210 is configured to control the opening of the blanking device and the throwing device in a case where the feed remaining in the feeder 200 increases beyond the weight threshold value within the second preset time period. The electronic control unit 210 automatically starts the blanking mode when detecting that the weight increase exceeds the threshold value within a predetermined time (i.e., the second preset time period), so that the fodder is prevented from being stuck in the throwing tray.

Since the load cell 140 of the feeder apparatus 1000 is in a high load and high vibration environment for a long period of time, the load cell 140 may drift after a period of continuous operation, resulting in measurement errors, and thus, the calibration of the weighing feet 100 needs to be performed periodically. The calibration process for the weighing feet 100 may be as follows: the electronic control device 210 is configured to obtain a first measurement value of the load cell 140 when the shortage detection device detects that the feed allowance in the feeder 200 is zero; after a preset weight of feed is loaded into the feeder 200, a second measured value and a user input value of the load cell 140 are obtained; the current feed margin within the feeder 200 is calculated based on the current measurement of the load cell 140, the first measurement, the second measurement, the user input value, and the net weight of the feeder 200.

Specifically, when the electronic control device 210 detects that no feed remains in the bin 220 through the feed shortage detection device, the sum T0 (i.e., the first measurement value) of the readings of the current weighing sensors 140 is automatically recorded and stored in the memory; when a user needs to calibrate, a certain amount of feed (assumed to be G1) is first put into the bin 220, then the weight of the feed (i.e. the user input value G1) is input through the input interface of the electronic control device 210, and a typical input mode can be that the feed is connected to the electronic control device 210 through a network or bluetooth on a mobile phone, or an interface capable of inputting numbers is arranged on the electronic control device 210, and after input, the electronic control device 210 records the sum T1 (i.e. the second measurement value) of the current readings of each weighing sensor 140 and stores the sum in a memory; after calibration, when the next weighing is performed, if the sensor to be read by the electronic control device 210 is T (i.e., the current measured value), and the net weight of the feeder 200 is G0, the residual feed amount G in the bin (i.e., the current feed allowance) satisfies g=g0+ (T-T0)/(G1-G0)/(T1-T0).

Aiming at the limitation that the current aquaculture feeder cannot accurately measure and track the feeding amount, the application provides the weighing support leg 100 and the feeder device 1000 which can accurately measure, and have the following advantages: 1. the residual feed amount can be accurately weighed, and the feeding data of each day is recorded, so that the feeding management efficiency is improved; 2. the feeding machine can be suitable for most of the existing feeding machines, and can be updated and reformed; 3. the installation is convenient, and the manufacturing cost is low; 4. the automatic calibration can be carried out, and the measurement accuracy is kept under the environment of high load and strong vibration; 5. the measurement process can be automatically managed in the feeding process, and user intervention is not needed; 6. the device can be suitable for mounting uneven terraces and is suitable for being mounted on various feeding tables; 7. can be suitable for use in open air, and can not be influenced by rainwater and other bad weather.
