Description
Technical Field
[0001] This utility model belongs to the field of pig feeding technology and relates to an intelligent feeding control device. Background Technology
[0002] my country is a major pig-producing country, with an annual output of over 700 million commercial pigs. With the vigorous development of my country's livestock and poultry farming industry, livestock farms are becoming increasingly numerous and large-scale. Currently, manual, timed feed addition is commonly used. However, this method requires workers to measure the feed weight and feed it separately, which is not only time-consuming and labor-intensive but also cannot guarantee the amount of feed or the timeliness of feeding. Water must also be added separately during feeding, increasing the workload of workers and not always yielding good results. Currently, most large-scale pig farms in my country are moving towards automated feeding, and intelligent precision feeding equipment is emerging in large numbers. However, stability and lifespan remain significant challenges, especially with the detection probes, which often experience poor contact, failing to control feed and water levels, resulting in overflowing feed troughs and severe feed waste. Solving the stability and lifespan issues of equipment as soon as possible is crucial to improving the economic efficiency of livestock farming and reducing the labor intensity of workers.
[0003] Therefore, a smart feeding control device is needed to reliably detect the amount of feed and water given to pigs during feeding to solve the above problems. Utility Model Content
[0004] To address the aforementioned problems, this invention proposes an intelligent feeding control device, which effectively solves the issues in the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The feed pipe is provided with a feed auger on the upper side, and an outlet pipe is connected to the lower side of the inlet pipe. A flow valve is provided between the outlet pipe and the inlet pipe. A fixing plate is fixedly connected to the rear side of the lower part of the outlet pipe, and a contact probe with a variable angle is provided on the front side of the fixing plate.

[0009] Preferably, the upper end of the contact probe has a through hole, and a fixing bolt passes through the through hole. The end of the fixing bolt near the fixing plate is threadedly connected to the fixing plate.
[0010] Preferably, a buckle is fixedly connected to the front side of the fixing plate, the contact probe passes through the inner side of the buckle, and a diagonal rod is fixedly connected to the bottom of the contact probe.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] The following is in conjunction with the appendix Figures 1 to 4 The specific embodiments of this utility model will be described in further detail.
[0023] Depend on Figures 1 to 4 As shown, this utility model includes a support frame 1, a water inlet pipe 2, a feed pipe 3, and a controller 4. In order to increase the stability of feeding, the water inlet pipe 2, the feed pipe 3, and the controller 4 are all fixedly connected to the upper side of the support frame 1. A feed auger 5 is provided on the upper side of the feed pipe 3, and a water outlet pipe 6 is provided on the lower side of the water inlet pipe 2. A connecting block 7 is provided between the water outlet pipe 6 and the water inlet pipe 2. A fixing plate 8 is fixedly connected to the rear side of the water outlet pipe 6. A contact probe 9 with a variable angle is provided on the front side of the fixing plate 8, and a feeding trough 12 is provided on the lower side of the contact probe 9.
[0024] It should be noted that the feeding auger 5 uses a DN100 series feeder, which is a well-known technology familiar to those skilled in the art, so it will not be described in detail in this embodiment. The solenoid valve 7 uses a Focmag series intelligent solenoid flow valve. Both the feeding auger 5 and the solenoid valve 7 are electrically connected to the controller 4. The controller 4 can control the closing of the feeding auger 5 and the solenoid flow valve, and can also control the output of the feeding auger 5 and the amount of water flowing out of the solenoid flow valve, thereby accurately matching the feed and water ratio.
[0025] In use, by setting a contact probe 9 with an adjustable angle, the contact probe 9 can rotate relative to the fixed plate 8 when the pig is eating, thereby reducing the probability of the pig damaging the contact probe 9.
[0026] Furthermore, by Figures 1 to 4 As shown, in order to reduce the probability of poor contact, an insulating tube 10 is fitted on the outside of the water outlet pipe 6. The insulating tube 10 is made of PVC material and can protect the water outlet pipe 6. A plastic-coated steel wire rope 11 is provided between the water outlet pipe 6 and the contact probe 9. The contact probe 9, the fixing plate 8, the plastic-coated steel wire rope 11, the water outlet pipe 6, and the connecting block 7 are all made of conductive material and can transmit current.
[0027] By setting the insulating pipe 10, the water outlet pipe 6 and the insulating pipe 10 can be fixed to the support frame 1 by U-shaped clamps. Under the action of the insulating pipe 10, the water outlet pipe 6 is not electrically connected to the support frame 1.
[0028] Furthermore, by Figures 1 to 4 As shown, in order to increase the service life of the device, the upper and lower sides of the plastic-coated steel wire rope 11 are respectively provided with a first lock 13 and a second lock 14 for fixing the plastic-coated steel wire rope 11. The first lock 13 is fixedly connected to the water outlet pipe 6 by welding, and the second lock 14 is fixedly connected to the upper part of the contact probe 9 by welding.
[0029] Additionally, it should be noted that the internal circuit board of the controller 4 is also equipped with a continuity detection circuit. The end of the water inlet pipe 2 away from the water outlet pipe 6 is connected to the positive terminal of the continuity detection circuit via a wire (the wire is not shown). The negative terminal of the continuity detection circuit is connected to the feeding trough 12. When feed and water are injected into the feeding trough 12 through the feed pipe 3 and the water inlet pipe 6, since the feed is small, the water outlet pipe 6 connected to the positive terminal of the continuity detection circuit and the contact probe 9 are not electrically connected to the feeding trough 12 through the feed. At this time, the continuity detection circuit detects that it is in an open circuit state and will continue to feed. As the feed increases, after the feed contacts the contact probe 9, the two terminals of the continuity detection circuit are connected. At this time, the continuity detection circuit detects that it is in a closed circuit state and will send a signal to the controller 4, which will stop the movement of the feeding auger 5 and stop the feeding operation.
[0030] Both the first latch 13 and the second latch 14 are 2mm diameter plastic-coated steel wire rope double-wire latches. Each of the left and right sides of the first latch 13 and the second latch 14 is provided with a fixing screw, which can tighten the plastic-coated steel wire rope 11 so that the upper and lower ends of the plastic-coated steel wire rope 11 can always be connected to the insulating tube 10 and the contact probe 9 respectively, maintaining its conductivity. The outer side of the plastic-coated steel wire rope 11 has a plastic coating. After the plastic is peeled off at both ends of the plastic-coated steel wire rope 11, the two ends are connected to the first latch 13 and the second latch 14 respectively.
[0031] Furthermore, by Figures 1 to 4 As shown, in order to increase the service life of the device, a through hole is provided at the upper end of the contact probe 9, and a fixing bolt 15 is inserted inside the through hole. The end of the fixing bolt 15 near the fixing plate 8 is threadedly connected to the fixing plate 8.
[0032] In use, the contact probe 9, the plastic-coated steel wire rope 11, and the water outlet pipe 6 ensure that one terminal of the continuity detection circuit is always electrically connected to the contact probe 9. By using the first latch 13 and the second latch 14 to fix the plastic-coated steel wire rope 11, damage to the material of the plastic-coated steel wire rope 11 caused by welding is avoided. It also ensures that the conductivity between the movable contact probe 9 and the fixed water outlet pipe 6 is not affected by the oxidation of the contact surface of the movable parts, which would cause poor contact, affect the stability of the probe sensing circuit, and lead to problems such as uncontrollable material and water.
[0033] Furthermore, by Figures 1 to 4 As shown, in order to increase the accuracy of the device detection, a buckle 16 is fixedly connected to the front side of the fixed plate 8, the contact probe 9 is inserted through the inside of the buckle 16, and a diagonal rod 17 is fixedly connected to the bottom of the contact probe 9.
[0034] In use, by setting the inclined rod 17, the contact probe 9 can easily contact the feed inside the feed trough 12. By setting the buckle 16, the rotation angle of the contact probe 9 relative to the fixed plate 8 can be limited, so that the contact probe 9 can always detect inside the feed trough 12.
[0035] Furthermore, by Figures 1 to 4 As shown, in order to increase the applicability of the device, a display screen 18 is provided on both the front and rear sides of the controller 4;
[0036] It should be noted that the controller 4 adopts a symmetrical structure with front and back sides. Its internal main control part adopts PLC controller 4, which will not be described in detail here. In the circuit board design, the display screen 18 and the buttons are arranged in the center. In this way, the display screen 18 can be installed on the front and back sides of the controller 4. In practical applications, since the equipment on both sides of the corridor is symmetrically arranged, one display screen 18 can always face the corridor, which is convenient for management.
[0037] A touch rod 19 is fixedly connected to the middle of the support frame 1, and the touch rod 19 is electrically connected to the controller 4;
[0038] It should be noted that the touch rod 19 is a microswitch detection structure, including an outer sleeve, an inner rod, and a microswitch. The microswitch is electrically connected to the controller 4. The outer sleeve is connected to the support frame 1 via a U-shaped clamp. The inner rod is slidably connected inside the outer sleeve, with a maximum sliding distance limit between them. When the touch rod 19 is in use, the inner rod is pushed upward by the touch rod, activating the microswitch and sending a signal to the controller 4. When the inner rod is released and falls, the microswitch is deactivated. When a pig touches the touch rod 19, it sends a signal to the controller 4 via the built-in microswitch, enabling the controller 4 to determine whether to feed or water the pig.
[0039] In use, this invention connects the water inlet pipe 2 to the feed inlet end of the feeding auger 5, respectively, to a water pipe for supplying water and a feed pipe for supplying feed. During operation, the controller 4 controls the start and stop of the feeding auger 5 and the feed output, thus feeding the feed into the trough 12. Simultaneously, water flows into the trough 12 through the water inlet pipe 2 and the water outlet pipe 6, ensuring precise feed proportioning. When the feed reaches a certain height, the contact probe 9 contacts the feed in the trough 12, establishing a continuity detection circuit and sending a signal back to the controller 4. The controller 4 then issues a stop command to the feeding auger 5. Stop feeding; in addition, when the pigs are feeding, under the action of the contact probe 9, the plastic-coated steel wire rope 11, and the water outlet pipe 6, the contact probe 9 can always be electrically connected to one of the terminals of the continuity detection circuit. By using the first latch 13 and the second latch 14 to fix the plastic-coated steel wire rope 11, damage to the material of the plastic-coated steel wire rope 11 caused by welding is avoided. It can also ensure that the conductivity between the movable contact probe 9 and the fixed water outlet pipe 6 is not affected by the oxidation of the contact surface of the movable part (the rotation between the contact probe 9 and the fixed plate 8), which would cause poor contact, affect the stability of the probe sensing circuit, and cause problems with uncontrolled feed and water.
[0040] This utility model has a novel structure, ingenious design, and simple and convenient operation. Through this design, it effectively achieves the purpose of increasing feeding stability, reducing the probability of poor contact, increasing the service life of the device, increasing the accuracy of device detection, and increasing the applicability of the device.
[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
