Description

Technical Field

[0001] This utility model is applied to the feed line controller of a breeding house, specifically involving a feed line controller full feed sensing delay circuit. Background Technology

[0002] Automated feeding systems in livestock farms use mechanical feeding lines to deliver feed at set times and in measured quantities, thereby reducing labor costs and feed waste. For example, Chinese patent CN202421384038.9 discloses an auger-type automated feeding line, which uses a motor to drive spiral blades to pull feed. Other feeding line devices replace the spiral blades with multiple discs driven by chains. To ensure accurate feeding, a full-load sensor is usually installed in the feed trough. The full-load sensor closes when empty and opens when full, and the system executes or stops the feeding operation based on the sensor signal.

[0003] However, in actual production environments, the full-load sensor may close or open due to interference (such as localized empty / full material caused by animals rooting for food, environmental signal interference, etc.), which is commonly known as "detection jitter". This jitter may cause interruption in the material pulling process and needs to be improved. Summary of the Invention

[0004] This utility model proposes a full-material sensor delay circuit for a material line controller to solve the jitter problem in full-material sensor, which is specifically achieved through the following technical means:

[0005] A material line controller full-material sensing delay circuit includes a rectifier module, a full-material sensor, an energy storage capacitor, a transistor, and a material dropping drive module. The material dropping drive module drives the material dropping mechanism and has a positive input terminal and a negative input terminal. The positive input terminal of the material dropping drive module is connected to the positive output terminal of the rectifier module, and the negative input terminal of the material dropping drive module is connected to the negative output terminal of the rectifier module via the transistor. The full-material sensor is connected between the positive output terminal of the rectifier module and the control electrode of the transistor, and it is closed when empty and open when full. The energy storage capacitor is connected to the output terminal of the full-material sensor.

[0006] Furthermore, a main resistor is provided between the output terminal of the full material sensor and the control electrode of the transistor, and an adjustable resistor module is connected in parallel across the main resistor. The adjustable resistor module includes a DIP switch and several branch resistors. The input terminals of each path of the DIP switch are connected to the output terminal of the full material sensor, and each output terminal of the switch is connected to a branch resistor.

[0007] Furthermore, a voltage regulator module and a filter module are provided between the positive and negative output terminals of the rectifier module. A resistor-capacitor (RC) step-down module is provided at the positive input terminal of the rectifier module.

[0008] Furthermore, the material feeding drive module includes an optocoupler and a bidirectional thyristor. The first input terminal of the optocoupler is connected to the positive output terminal of the rectifier module, and the second input terminal of the optocoupler is connected to the negative output terminal of the rectifier module via a transistor. The first and second output terminals of the optocoupler are respectively connected to the two ends of the bidirectional thyristor via current-limiting resistors. The bidirectional thyristor is connected in series in the power supply line of the material feeding mechanism, and its control terminal is connected to the second output terminal of the optocoupler.

[0009] Furthermore, the material feeding drive module includes a relay. One end of the electromagnetic part of the relay is connected to the positive output terminal of the rectifier module, and the other end is connected to the negative output terminal of the rectifier module via a transistor. The switching part of the relay is connected in series to the power supply line of the material feeding mechanism.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the fast charging and slow discharging of the energy storage capacitor realizes the anti-shaking detection of the full material sensor. In particular, under AC 220V conditions, the full material switch anti-interference and configurable delay disconnection are realized by pure hardware. Even if there is a situation of empty / full material in a local position of the material line, it can ensure that the complete material pulling can be completed without interruption of the material pulling process due to erroneous actions.

[0012] Figure 2 This is a schematic diagram of the full-material sensing delay circuit of the material line controller in Example 2. Detailed Implementation

[0013] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0014] Example 1

[0015] See appendix Figure 1 The full material sensing delay circuit of the material line controller includes a rectifier module D1, a full material sensor S1, an energy storage capacitor C3, a transistor Q1, and a material dropping drive module.

[0016] The material feeding drive module is used to drive the material feeding mechanism. It includes an optocoupler U1 and a bidirectional thyristor TR1. The first input terminal of the optocoupler U1 (i.e., the positive input terminal of the material feeding drive module) is connected to the positive output terminal of the rectifier module D1 via a resistor R1. The second input terminal of the optocoupler U1 (i.e., the negative input terminal of the material feeding drive module) is connected to the negative output terminal of the rectifier module D1 via a transistor Q1. The first output terminal of the optocoupler U1 is connected to one end of the bidirectional thyristor TR1 via a current-limiting resistor R2. The second output terminal of the optocoupler U1 is connected to the other end of the bidirectional thyristor TR1 via a current-limiting resistor R5. The bidirectional thyristor TR1 is connected in series in the power supply line of the material feeding mechanism, and its control terminal is connected to the second output terminal of the optocoupler U1.

[0017] The full-load sensor S1 is connected between the positive output terminal of the rectifier module D1 and the control terminal of the transistor Q1. It is closed when empty and open when full. The energy storage capacitor C3 is connected to the output terminal of the full-load sensor S1. A main line resistor R12 is provided between the output terminal of the full-load sensor S1 and the control terminal of the transistor Q1. An adjustable resistor module is connected in parallel across the main line resistor R12. The adjustable resistor module includes a DIP switch J1 and branch resistors R6, R7, R8, and R10. The input terminals (pins 1, 3, 5, and 7) of the DIP switch are all connected to the output terminal of the full-load sensor S1, and the output terminals (pins 2, 4, 6, and 8) are each connected to a branch resistor. By setting the on / off state of each channel of the DIP switch J1, one or more of the branch resistors R6, R7, R8, and R10 can be selected to be connected in parallel with the main line resistor R1, thereby adjusting the equivalent resistance value.

[0018] When the full feed sensor S1 detects no feed, it closes. The AC220V power supply, after being rectified by the rectifier module D1, charges the energy storage capacitor C3 through resistor R11 and diode D2. The energy storage capacitor C3 then supplies power to the control electrode of transistor Q1 through the main line resistor R1 and branch line resistors R6 / R7 / R8 / R10, causing it to conduct. This triggers the optocoupler U1, causing the bidirectional thyristor TR1 to connect the power supply lines AC220_OUT1 and AC220_OUT2 of the feeding mechanism, executing the feeding operation.

[0019] When the full-material sensor S1 detects a full load, it disconnects. Although the power supply is lost, the energy storage capacitor C3 can still power the transistor Q1 for a certain period of time, keeping it conducting and continuing the material feeding operation until the energy storage capacitor C3 is depleted, at which point the transistor Q1 turns off and the feeding stops. This fast charging and slow discharging of the energy storage capacitor C3 achieves de-jitter detection of the full-material sensor S1, avoiding interference from abnormal signal fluctuations during the detection process (such as empty / full sections of the feed line due to animal feeding, environmental signal interference, etc.), ensuring complete material feeding without interruption due to erroneous actions. The duration can be configured by the equivalent impedance of the main line resistor and branch line resistor, as well as the capacitance of the energy storage capacitor C3, enabling a simple and reliable pure hardware control scheme under AC 220V conditions.

[0020] Preferably, the positive input terminal of the rectifier module D1 is provided with a resistor-capacitor step-down module, which includes a capacitor C2 and a resistor R9 connected in parallel. It is powered by an RC step-down circuit. When the power supply is disconnected, the resistor R9 discharges the electrical energy at the positive input terminal of the rectifier module D1 to avoid electric shock.

[0021] Preferably, a voltage regulator module and a filter module are provided between the positive and negative output terminals of the rectifier module D1; the voltage regulator module includes a Zener diode D3, whose anode is connected to the negative output terminal of the rectifier module D1 and whose cathode is connected to the positive output terminal of the rectifier module D1. The filter module includes a resistor R3 and an electrolytic capacitor C1 connected in parallel.

[0022] Preferably, an indicator light module LD1 is provided between the positive output terminal of the rectifier module D1 and the transistor Q1, which is used to illuminate the light to indicate the working status of the circuit when the transistor Q1 is turned on.

[0023] Example 2

[0024] See appendix Figure 2 The circuit structure is roughly the same as that in Embodiment 1 above, except that the thyristor scheme is replaced with a relay scheme in the material feeding drive module. That is, one end of the electromagnetic part of the relay K1 is connected to the positive output terminal of the rectifier module D1, and the other end is connected to the negative output terminal of the rectifier module D1 through the transistor Q1. The switching part of the relay K1 is connected in series to the power supply line of the material feeding mechanism.

[0025] When the full-material sensor S1 detects an empty material, it closes. The AC220V power supply, after being rectified by the rectifier module D1, charges the energy storage capacitor C3 through resistor R11 and diode D2. The energy storage capacitor C3 then supplies power to the control electrode of transistor Q1 through the main line resistor R1 and branch line resistors R6 / R7 / R8 / R10, causing it to conduct. This triggers relay K1, which in turn connects the power supply lines AC220_OUT1 and AC220_OUT2 of the material feeding mechanism, executing the material feeding operation.

[0026] When the full material sensor S1 detects that the material is full, it disconnects. The energy storage capacitor C3 supplies power to the transistor Q1 for a certain period of time, keeping it conducting and continuing to perform the material feeding operation until the energy storage capacitor C3 is depleted, at which point the transistor Q1 turns off and the material feeding stops.

[0027] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
