Description

[0002] Laying hen water supply and medication breeding equipment is an indispensable part of modern chicken farms. This equipment can ensure that laying hens have sufficient and clean drinking water and medicines, thereby improving breeding efficiency and economic benefits.

[0003] Most of the existing laying hen water supply and drug administration equipment directly supply cold water to laying hens for feeding. At the same time, when feeding laying hens with medicine, most of the drugs are manually introduced into the water tank for mixing. Although the above operation can supply water and various drugs to laying hens, the above feeding of laying hens with cold water can easily cause stress reactions in laying hens, thereby affecting the subsequent drug administration effect. At the same time, the drugs are manually added to the water tank, the uniformity of the drug mixing is low, and the manual drug administration time is arbitrary, which reduces the regularity of feeding laying hens. At the same time, the existing traditional drinking water heating operation is insufficient in environmental protection and energy saving, and the equipment is shut down after power failure, which is not convenient for adaptive operation. Therefore, an energy-saving laying hen water supply and drug administration device is needed to solve the above problems. Summary of the invention

[0043] The negative pressure one-way valve 36 is connected to the sealed liquid guiding box 31 through the docking conduit 33. The liquid guiding piston 34 is adapted to the threaded guide shaft 39 through the threaded sleeve 35 and then sealed and slidably connected to the inner wall of the sealed liquid guiding box 31. The threaded guide shaft 39 can push the liquid guiding piston 34 to move forward and backward inside the sealed liquid guiding box 31 through the threaded connection with the threaded sleeve 35, so that the liquid guiding piston 34 can absorb the medicine inside the liquid storage tank 38, and then introduce an equal amount into the buffer tank 66, thereby improving the efficiency of subsequent feeding of laying hens.

[0044] The sealed liquid guiding box 31 is connected to the interior of the buffer tank 66 through the positive pressure one-way valve 32, and the liquid separation box body 45 is sealed and fixedly connected to the supporting conduit 52 through the guide tube 44.

[0045] The stepper motor 310, the drive module 54, the timing module 55 and the servo motor 62 are all electrically connected to the battery module 2, so that when the AC power is lost, the battery module 2 can continue to ensure the operation of the equipment, thereby improving the stability of the equipment operation.

[0046] The water outlet conduit 67 is fixedly connected to the support conduit 52, the heating module 65 does not contact the bottom and side of the buffer tank 66, and the mixing blade 61 does not contact the heating module 65. The heating module 65 is located inside the buffer tank 66 close to the outside, which can effectively improve the heating efficiency of the water source. At the same time, the mixing blade 61 does not contact the heating module 65, which can prevent subsequent damage to the heating module 65 and improve the mixing uniformity of the medicine solution.

[0047] Working principle: Before use, the staff can connect the external cold water supply pipeline with the water inlet conduit 68 to facilitate the subsequent continuous supply of cold water. Then, the various drugs required to feed the laying hens can be introduced into the liquid storage tank 38 through the feed conduit 37, so as to facilitate the subsequent continuous supply of liquid medicine to the buffer tank 66. At the same time, the staff can position the control panel adapted to the equipment to the side of the limit base 42 to facilitate the subsequent rapid control of the entire equipment. Under normal conditions, the control panel, stepper motor 310, drive module 54, timing module 55 and servo motor 62 are all controlled by the external AC. When heating the water source in the buffer tank 66, the solar photovoltaic panel 7 can generate electricity through external light energy, and then introduce it into the battery module 2 through the conversion control module 1. The battery module 2 transmits the electric energy to the power supply guide ring 64 through electronic components such as inverters. At this time, the power supply guide ring 64 can heat the water source in the buffer tank 66 synchronously through multiple groups of heating modules 65. When it is not necessary to give medication to the laying hens, the timing module 55 can start the driving module 54 at a predetermined time through a pre-programmed schedule, and the driving module 54 can drive the water guide pump 51 to operate, so that the inside of the buffer tank 66 Under the suction of the water guide pump 51, the water source is introduced into the liquid separation box 45 through the support guide tube 52. The liquid separation box 45 can evenly distribute the water source to multiple groups of automatic drinking fountains 43 for laying hens, and then feed the laying hens with water. If it is necessary to give medication to the laying hens, the staff can start the stepper motor 310 through the control panel. The stepper motor 310 can drive the threaded guide shaft 39 to reverse, so that the threaded guide shaft 39 can drive the liquid guide piston 34 to move toward the fixed seat 311 through the threaded sleeve 35, so that the inside of the sealed liquid guide box 31 is in a negative pressure state. At this time, the liquid in the liquid storage tank 38 passes through the negative pressure one-way valve 3 6 and the docking conduit 33 are introduced into the sealed liquid guiding box 31, and the positive pressure one-way valve 32 is in a closed state. After reaching the specified volume, the stepper motor 310 rotates forward. At this time, the stepper motor 310 can drive the liquid guiding piston 34 to move forward through the threaded guide shaft 39. The sealed liquid guiding box 31 is high pressure, the negative pressure one-way valve 36 is closed, and the positive pressure one-way valve 32 is opened, and the liquid medicine is transported to the buffer tank 66. At the same time, the servo motor 62 can mix the liquid medicine through the mixing blade 61. When the power is off, the electric energy stored in the above-mentioned battery module 2 can continuously supply the power consumption of the equipment, thereby improving the stability of the equipment in feeding laying hens.
