DETAILED DESCRIPTION

[0027] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] like Figure 1 、 2 In the embodiment shown in FIG5 , a mobile cart 109 is used to mount a liquid medicine storage tank 114, a dosing mechanism, and a power source. The structure of the mobile cart 109 can be constructed using high-strength channel steel, angle steel, or bar steel as a support frame. To facilitate the movement of the mobile cart 109, a handle 101 is provided at one end. To ensure the safety of the various functional components of the mobile cart 109, a cover 120 is provided.

[0030] The liquid medicine storage tank 114 is used to store the configured liquid medicine. The liquid medicine storage tank 114 can be made of stainless steel, polyethylene, ABS engineering resin, etc.

[0031] The medicine feeding mechanism is used to evenly deliver the liquid medicine to each nozzle 103 according to the set dosage, and apply the liquid medicine to the trough of the chicken house through each nozzle 103. Specifically, the medicine feeding mechanism includes a plurality of cylinders 106 and electric push rods 110. Each cylinder 106 is arranged in parallel and fixedly connected to the mobile trolley 109 via a mounting seat 111. The electric push rod 110 and the mobile trolley 109 are fixedly connected. The piston 116 provided at each cylinder 106 is slidably connected to the inner wall of the cylinder 106. The closed area between the cylinder 106 and the piston 116 is the inner cavity of the cylinder 106. The inner cavity of each cylinder 106 is intersected with the liquid medicine storage tank 114 through the first conduit 113, and the inner cavity of each cylinder 106 is intersected with the nozzle 103 through the second conduit 105. One-way valves installed in each first conduit 113 and each second conduit 105 ensure unidirectional flow of the drug solution within these conduits. The movement of the piston 116 changes the pressure within the cylinder 106, allowing the drug solution to be drawn in and out. The electric push rod 110 drives the pistons 116 to move synchronously, ensuring that the amount of drug solution drawn in and out of each cylinder 106 is equal during operation.

[0032] An optional structure in which the electric push rod 110 drives each piston 116 to move synchronously is that an adjusting rod 107 is provided at the end of each piston 116, and the end of each adjusting rod 107 is respectively connected to the connecting plate 108, and the telescopic rod of the electric push rod 110 is connected to the connecting plate 108.

[0033] When the medicine feeding mechanism is in operation, the electric push rod 110 retracts, generating negative pressure within each cylinder 106. The liquid medicine stored in the liquid medicine storage tank 114 enters the cylinder 106 through the first conduit 113, thereby completing the absorption of the liquid medicine. When the electric push rod 110 pushes out, positive pressure is generated within the cylinder 106. The liquid medicine stored in each cylinder 106 is delivered to the corresponding nozzle 103 through the second conduit 105, and then sprayed by the nozzle 103 onto the trough in the chicken house. The electric push rod 110 is quiet during operation, so it does not disturb the chickens.

[0034] The support rods 104 provided at the mobile trolley 109 are used to install the cantilevers 102 , and the cantilevers 102 allow the nozzles 103 to be suspended above the troughs in the chicken house.

[0035] The power supply is used to supply power to the electric push rod 110 , wherein the power supply can be in the form of a lead-acid battery or a lithium battery.

[0036] During use, the trough in the chicken house is pre-filled with chicken feed. The position of the mobile cart 109 is adjusted so that each nozzle 103 is located above the trough. The electric push rod 110 is pre-retracted to draw the liquid medicine into each cylinder 106. Once this action is complete, the push rod 110 is extended, simultaneously pushing the mobile cart 109 forward at a constant speed. The liquid medicine stored in each cylinder 106 is then delivered to each nozzle 103 through the second conduit 105 by the push rod 110 and evenly sprayed onto the trough in the chicken house. The chickens ingest the medicine along with it as they eat.

[0037] Example 2:

[0038] On the basis of Example 1, Figure 2 In the illustrated embodiment, to ensure airtightness between the piston 116 and the cylinder 106, each piston 116 is provided with a plurality of protrusions 115 along its circumference. The protrusions 115 can be made of silicone or rubber. One optional connection method is to bond the protrusions 115 to the circumference of the piston 116. Another optional connection method is to provide an annular protrusion 115 that is secured to the circumference of the piston 116 via an annular groove provided on the circumference of the piston 116.

[0039] Example 3:

[0040] On the basis of Example 1 or 2, as Figure 2 In the illustrated embodiment, in order to reduce the friction between the piston 116 and the inner wall of the cylinder 106, a polytetrafluoroethylene coating is provided on the inner wall of each cylinder 106 due to the self-lubricating property of polytetrafluoroethylene.

[0041] Example 4:

[0042] On the basis of any one of Examples 1-3, Figure 3 In the illustrated embodiment, when the chicken houses are of different sizes, in order to adjust the relative height of each nozzle 103 and the chicken house trough so that the liquid medicine is better sprayed into the chicken house trough, each cantilever 102 is provided with a guide sleeve 117 at the end opposite the nozzle 103. Each guide sleeve 117 is sleeved on the support rod 104 and fixed to the support rod 104 by a fastener. The fastener can be in the form of a screw or a threaded pin.

[0043] Example 5:

[0044] On the basis of any one of Examples 1-4, Figure 1 In the embodiment shown, in order to ensure that the moving trolley 109 moves in a straight line during movement, a guide rail 112 is added in this embodiment. The guide rail 112 is set on the ground of the chicken house, and a groove that cooperates with the guide rail 112 is set on the guide wheel on one side of the moving trolley 109.

[0045] Example 6:

[0046] On the basis of any one of Examples 1-5, Figure 4 In the illustrated embodiment, when the medicinal liquid is prepared by boiling traditional Chinese medicine, in order to filter out impurities in the medicinal liquid and prevent pipeline blockage, a filter assembly is provided at the mouth of the medicinal liquid storage tank 114. The filter assembly includes a frame 118, and a filter mesh 119 is provided at the frame 118. In order to increase the filtering area, the filter mesh 119 is made of flexible material.

[0047] Example 7:

[0048] On the basis of any one of Examples 1-6, Figure 6 In the illustrated embodiment, a control unit and a drive motor are added to the drug delivery device so that the drug delivery device can automatically spray the drug solution, prevent the operator from inhaling the drug solution during operation, and ensure uniform drug spraying. The drive motor is installed on the mobile cart 109 to provide power for the mobile cart 109 to move. The control unit is used to control the drive motor and the electric push rod 110 to perform actions. Specifically, the control unit is provided with several I / O interfaces. The drive motor is connected in parallel with the power supply via a relay, and the relay and the electric push rod 110 are electrically connected to the corresponding I / O interfaces of the control unit. The control unit can control the drive motor via the relay, and the electric push rod 110 transmits the position signal of the telescopic rod to the control unit in real time.

[0049] During use, the device is turned on. S1: The control unit sends a disconnection command to the relay and simultaneously sends a retraction command to the electric push rod 110 until the telescopic rod of the electric push rod 110 has retracted to its maximum stroke. S2: When the control unit detects that the electric push rod 110 has retracted to its maximum stroke, it sends a conduction signal to the relay, causing the drive motor to start running and simultaneously sends a retraction command to the electric push rod 110. At this time, driven by the drive motor, the mobile carriage 109 moves at a constant speed, spraying the liquid medicine delivered by the dosing mechanism evenly into the trough through the nozzle 103.

[0050] It is understood that the functions of the control unit are implemented by the control unit hardware itself and the program installed in the control unit. It should be noted that the program is written based on the working principle of the drug delivery device for the stacked chicken house described in Example 1. The specific assembly language, function calls, and data debugging methods used in the program writing are all prior art, and the program installed in the control unit of this application is not protected by this solution.

[0051] The control unit chip may be a single chip microcomputer or a PLC programmable controller.

[0052] The embodiments described above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention based on the technical solution and utility model concept of the present invention, which should be covered within the protection scope of the present invention.
