Description

Technical Field

[0001] The utility model relates to the technical field of livestock feeding equipment, in particular to an automatic liquid feed medicating system. Background Art

[0002] In recent years, liquid feed feeding systems have been widely used in the pig breeding industry, significantly improving the feeding efficiency and feed conversion rate; this system usually includes a set of complex equipment chains, from the precise proportioning and mixing of dry feed and water to the distribution of the prepared liquid feed to each feeding trough in the pig house through a pipeline system, and every step strives for precision and efficiency. Among them, in order to improve the preparation efficiency of liquid feed, the volume of the mixing tank is usually relatively large. For example, the liquid feed mixing tank currently used by our company can feed 500 - 1000 pigs in one mixing, and the feeding amount each time ranges from several hundred kilograms to several thousand kilograms; such a large feeding amount requires strict control of the preparation ratio, and this process is mainly achieved through the weighing system set on the mixing tank, which can accurately control the feeding amount of water, materials for liquid feed preparation, and each valve during liquid feed distribution to ensure that each pig can obtain a nutritionally balanced feed supply.

[0003] However, in actual production, in order to meet the health needs of specific pig groups or optimize production performance, pig farms need to add trace additives such as drugs, vitamins, or lactic acid bacteria to the feed at specific stages. The addition amount of these additives is extremely small, usually a few per thousand of the total feed amount, or even lower; due to the small addition amount, for the weighing system of the mixing tank used to monitor several thousand kilograms of feed, the accuracy generally cannot meet the requirements of these additives.

[0004] Therefore, at present, most pig farms adopt the method of manual addition, adding additives manually to the mixing tank or prefabricated tank every time liquid feed is prepared. When implementing this solution in actual operation, it is necessary for workers to first prepare and weigh the additives and add them to the liquid feed on time. This process is very time-consuming and laborious, and at the same time, the manual addition process is also prone to misoperation or contamination of the batching system; in addition, the mixing tank body is usually relatively high, and when adding, operators need to work at heights, increasing the safety risk of operators. Summary of the Utility Model

[0005] The utility model provides an automatic liquid feed medicating system, which can solve the technical problems of the existing drug addition operation being time-consuming, laborious, and having low efficiency.

[0043] Embodiment 1

[0044] As Figure 1-2 shown, a liquid material automatic drug addition system includes a weighing and lifting device 1, a horizontal feeding device 2, a blanking device 3, and a control system for controlling the start and stop of the weighing and lifting device 1, the horizontal feeding device 2, and the blanking device 3; the discharge end of the weighing and lifting device 1 is communicated with the feeding end of the horizontal feeding device 2, the horizontal feeding device 2 is arranged on the top of the mixing tank 100, and the blanking device 3 is arranged between the horizontal feeding device 2 and the mixing tank 100 for blanking the additives in the horizontal feeding device 2 into the mixing tank 100; the additives in this embodiment are not limited to drugs, and can also be vitamins, lactic acid bacteria, or other powdery additives.

[0045] As Figure 3 shown, the weighing and lifting device 1 includes a mounting frame 11, a silo 12, a weigher 13 and a lifting mechanism. There are multiple weighers 13 which are evenly arranged on the top of the mounting frame 11. The silo 12 is suspended in the mounting frame 11 through the weighers 13. The weighers 13 are electrically connected to the control system and are used to send weighing data to the control system. Specifically, in this embodiment, the weigher 13 adopts a beam type weighing sensor, which can provide high-precision measurement, is applicable to a wide weight range from a few grams to several tons, has high reliability and durability, and is suitable for long-term use in industrial environments. Moreover, the output signal is stable and not affected by the change of the force measuring point position, which can ensure the accuracy and consistency of the measurement.

[0046] The bottom of the silo 12 in this embodiment is of a conical structure. The feeding end of the lifting mechanism is communicated with the discharging port of the silo 12, and the discharging end of the lifting mechanism is communicated with the feeding end of the horizontal feeding device 2. Specifically, the lifting mechanism includes a lifting screw conveyor, and the lifting screw conveyor includes a lifting motor 141 and a lifting pipe 142. The lifting motor 141 is electrically connected to the control system. In order to better connect the silo 12 and the lifting pipe 142 in this embodiment, a pushing hopper 121 is also obliquely arranged at the bottom of the silo 12, and the pushing hopper 121 is communicated with the lifting pipe 142. In order to further ensure the connection stability, a strengthening arm 15 is also arranged between the upper side wall of the silo 12 and the lifting pipe 142, so that the silo 12 is vertically suspended.

[0047] During the actual feeding process, the materials in the silo 12 may form an arch structure. As Figure 4-5 shown, a arch-breaking component is also arranged in the silo 12 in this embodiment. The arch-breaking component includes a dial rod 5. The upper end of the dial rod 5 is bent to form a hinge part 51 and a connecting part. A fixing plate 56 is also arranged at the top of the silo 12. An arch-breaking driving part electrically connected to the control system is arranged on the fixing plate 56. The hinge part 51 of the dial rod 5 is movably connected to the fixing plate 56, and the connecting part is connected to the arch-breaking driving part. The arch-breaking driving part is used to drive the dial rod 5 to move.

[0048] Specifically, in this embodiment, the arch-breaking driving member includes an arch-breaking cylinder 6 and an arch-breaking solenoid valve 61. The arch-breaking solenoid valve 61 is electrically connected to the control system. The arch-breaking cylinder 6 is vertically arranged on the fixed plate 56.

The U-shaped block is movably connected to the strip-shaped hole 52 through a rotating shaft. When the control system controls the on-off of the arch-breaking solenoid valve 61, the piston rod of the arch-breaking cylinder 6 makes a telescopic movement, thereby pushing the dial rod 5 to rotate around the hinged portion 51, so that the bottom of the dial rod 5 stirs the additive below the feed bin 12. In order to further improve the stirring effect, in this embodiment, the bottom of the dial rod 5 is also bent, and a disturbance plate 53 is arranged on its bent portion. The disturbance plate 53 is of an S-shaped structure.

[0049] As Figure 1 shown, the horizontal feeding device 2 includes a horizontal screw conveyor. The horizontal screw conveyor includes a horizontal motor 22 and a horizontal feeding pipe 21. The horizontal motor 22 is electrically connected to the control system. A transfer hopper 23 communicated with it is also arranged on the horizontal feeding pipe 21. The discharge end of the lifting pipe 142 is communicated with the transfer hopper 23.

[0050] As Figure 6 shown, the feeding device 3 includes a feeding pipe 31 and a feeding valve arranged on the feeding pipe 31. The feeding valve is electrically connected to the control system. One end of the feeding pipe 31 is communicated with the horizontal feeding pipe 21, and the other end is communicated with the mixing tank 100. Specifically, the feeding valve includes a feeding push plate 33 and a feeding cylinder 32. The feeding cylinder 32 is also connected with a feeding solenoid valve 321. The feeding push plate 33 is connected to the piston rod of the feeding cylinder 32. In this embodiment, an installation plate 34 is also hermetically arranged between the feeding pipe 31 and the horizontal feeding pipe 21. The bottom of the installation plate 34 is connected to the feeding pipe 31, and the top is fixed on the horizontal feeding pipe 21 through a U-shaped bolt 341. The feeding push plate 33 is slidably and hermetically arranged on the installation plate 34. The feeding cylinder 32 and the feeding solenoid valve 321 are arranged on the side wall of the installation plate 34. When the control system controls the on-off of the feeding solenoid valve 321, the piston rod of the feeding cylinder 32 expands and contracts to drive the feeding push plate 33 to move, so as to open or close the feeding pipe 31.

[0051] At least two groups of weighing and lifting devices 1 are provided for storing and conveying different additives, and a transfer hopper 23 is arranged at the connection between the lifting pipe 142 of each weighing and lifting device 1 and the horizontal feeding pipe 21; at least two groups of mixing tanks 100, and a group of feeding devices 3 are arranged on each mixing tank 100. Specifically, as Figure 1As shown in the figure, this embodiment takes two sets as an example for illustration. The two weighing and lifting devices 1 are arranged side by side on one side of the two mixing tanks 100. The weighing and lifting devices 1 can convey different additives simultaneously as needed, or selectively convey a certain drug at different stages. For the multiple mixing tanks 100 provided, according to the pig groups fed by the feed prepared in each mixing tank 100, the feeding device 3 can be used to open a certain mixing tank 100, and then add the drug into the required mixing tank 100.

[0052] The control system of this embodiment includes a control cabinet 4 and a controller arranged in the control cabinet 4. The controller can adopt a PLC controller. The control cabinet 4 can be arranged on the installation frame 11 or on the top of the silo 12. And on the outer surface of the control cabinet 4, there are also a display screen and an operation screen (not shown in the figure) electrically connected to the controller. The display screen can display information such as the weight value detected by the weigher 13, the amount of drug conveyed each time, and the cumulative consumed drug amount. And through the operation screen, the set drug to be added and the timing of addition can be input.

[0053] An alarm is also provided in this embodiment. The alarm is electrically connected to the controller. When the weight of the additive in the silo 12 is insufficient, the alarm emits an alarm signal to remind the breeder to add. Or, when detecting the weight change during the operation of the equipment, if the lifting motor 141 rotates and the weight does not change, it indicates that the additive may be insufficient or there is a bridging situation. The alarm also emits an alarm and simultaneously activates the anti-bridging component.

[0054] Before use, add the drug into the silo 12, then set the addition amount and addition time through the operation screen, and use the controller to automatically control the start of the lifting motor 141 and the horizontal motor 22, so as to sequentially convey the drug in the silo 12 into the lifting pipeline 142 and the horizontal feeding pipeline 21, and then add the drug into the required mixing tank 100 through the feeding device 3. During this process, the weigher 13 can detect the amount of drug conveyed in real time. When the amount of drug conveyed reaches the set addition amount, close each conveying system, thereby realizing the automatic drug addition function for liquid feed, and solving the technical problems of the existing drug addition operation being time-consuming, laborious, and having low efficiency.

[0055] The above are only the embodiments of the present utility model. The present utility model is not limited to the fields involved in this embodiment.
