Description

Technical Field

[0001] This invention relates to the field of dairy cow breeding technology, and in particular to a dairy cow self-service drinking device, a dairy cow self-service drinking system, and a dairy cow breeding and management method. Background Technology

[0002] A dairy cow's water intake is a complex indicator influenced by a variety of factors. Generally, a dairy cow drinks 5% to 6% of its body weight. However, the amount of water consumed varies depending on the cow's stage of production: lactating cows, which require more water to produce milk, drink significantly more water than non-lactating cows. Therefore, a dairy cow's water intake is closely related to its health.

[0003] In existing free-range cattle sheds, cattle generally share water troughs, which cannot guarantee water quality and temperature. In summer or winter, cattle are prone to heat stress or cold stress. Shared water troughs require cattle to walk from their beds to the troughs, and some cattle may have limb problems that make it difficult for them to walk, thus failing to ensure sufficient water intake. Existing cattle farm watering facilities cannot monitor the daily water intake of each cow in real time. If individual cows do not drink enough water, it can easily affect the health of dairy cows.

[0004] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the inability to perform precise management of cattle, low management efficiency, and the increased management difficulty due to unstable drinking water temperature causing stress in dairy cows. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a self-service drinking device, a self-service drinking system, and a method for dairy cow feeding and management, in order to solve problems such as the inability to perform refined management of cattle, low management efficiency, and increased management difficulty due to inconsistent drinking water temperature causing stress in dairy cows.

[0099] like Figure 3 As shown, the switching unit 120 includes a switching element 121 and a second limiting element 122. The switching element 121 is slidably disposed inside the drinking unit 110. A pressure sensing unit 170 is disposed at the bottom of the switching element 121 and is limitedly connected to the movable unit 130. This unit controls the connection or closure of the drinking unit 110 and the liquid storage device by reciprocating vertically under the action of the movable unit 130. The second limiting element 122 is disposed at the top of the switching element 121 and is limitedly connected to the drinking unit 110 to prevent the switching element 121 from separating from the drinking unit 110.

[0100] Specifically, the switching element 121 is slidably disposed at the bottom of the conveying element 112 and is slidably connected to the first limiting element 113; the second limiting element 122 is slidably connected to the conveying element 112 and is limitedly connected to the first limiting element 113.

[0110] In some of these embodiments, the second limiting element 122 has a circular cross-section.

[0111] In some of these embodiments, the second limiting element 122 is a blocking piston.

[0112] Furthermore, the switch unit 120 also includes a sealing element 123. The sealing element 123 is disposed at the bottom of the second limiting element 122 and is used to seal the gap between the switch element 121, the second limiting element 122 and the drinking water unit 110.

[0113] Specifically, the sealing element 123 is used to block the gap between the switching element 121, the second limiting element 122 and the first limiting element 113.

[0114] In some embodiments, the connection between the sealing element 123 and the second limiting element 122 includes, but is not limited to, adhesive bonding.

[0120] like Figure 4 As shown, the movable unit 130 includes a movable element 131 and a second rotating element 132. The movable element 131 is rotatably disposed inside the drinking water unit 110 and is sleeved on the lower end of the switch unit 120. The movable element 131 is limitedly connected to the switch unit 120 and is used to drive the switch unit 120 to reciprocate in the vertical direction. The second rotating element 132 is disposed on the side of the movable element 131 and is rotatably connected to the drinking water unit 110.

[0121] Specifically, the movable element 131 is rotatably disposed inside the drinking element 111 and located below the conveying element 112. The movable element 131 is sleeved on the bottom end of the switching element 121. The second rotating element 132 is rotatably connected to the first rotating element 115.

[0123] In some of these embodiments, the cross-section of the active element 131 is annular.

[0124] In some of these embodiments, the movable element 131 includes, but is not limited to, a movable sleeve.

[0125] When the switching unit 120 blocks the conveying element 112, that is, when the second limiting element 122 abuts against the first limiting element 113, the position of the second rotating element 132 is higher than the bottom end of the switching element 121.

[0126] In some embodiments, the connection between the second rotating element 132 and the movable element 131 includes, but is not limited to, screw connection and welding.

[0127] In some of these embodiments, the second rotating element 132 is a rotating hinge.

[0128] The method of using this invention is as follows:

[0129] (a) Closed state

[0130] When the cow is not drinking, the movable element 131 hangs down under its own weight and separates from the switch element 121.

[0131] The second limiting element 122 blocks the first limiting element 113 under its own weight (or, under the pressure of the water in the conveying element 112), preventing the water from flowing out of the conveying element 112.

[0132] At this time, the pressure sensing unit 170 is not subjected to external pressure and does not send signals to the timing unit 150 and the recognition unit 160. The timing unit 150 and the recognition unit 160 are in a non-working state.

[0133] (II) On State

[0134] When the cow is drinking, it licks the moving element 131, which rotates upward and simultaneously blocks the switch element 121, which slides upward along the conveyor element 112.

[0135] The second limiting element 122 separates from the first limiting element 113, and the water flows along the first limiting element 113 and the movable element 131 into the drinking element 111 to provide water for the dairy cows;

[0136] At this time, the pressure sensing unit 170 receives external pressure and sends signals to the timing unit 150 and the identification unit 160. The timing unit 150 is activated, records the time when the pressure sensing unit 170 receives the pressure and transmits the data to the data processing unit 180. The identification unit 160 is activated, identifies the information recording device worn by the cow and transmits the data to the data processing unit 180.

[0137] After recording the information for the corresponding time period, the data processing unit 180 processes and matches the information to complete the recording of the dairy cow's drinking status.

[0138] The advantage of this invention is that by setting a pressure sensing unit at the bottom of the switching unit and controlling the opening and closing of the corresponding timing unit and the corresponding identification unit through the pressure sensing unit, the drinking status of different cattle can be recorded, thus solving the problem of low management efficiency and inability to carry out refined management of cattle.

[0139] Example 2

[0140] This embodiment relates to the self-service drinking water system for dairy cows of the present invention.

[0141] like Figure 5 As shown, a self-service drinking system for dairy cows includes at least one self-service drinking device 100 as described in Embodiment 1 and at least one information recording device 200. The information recording device 200 is disposed on the neck or ear of the cow and is communicatively connected to the identification unit 160 of the self-service drinking device 100 for recording cow information.

[0142] In some embodiments, there are multiple self-service drinking devices 100. These self-service drinking devices 100 are spaced apart along the outer side of the cattle bed.

[0143] The number of information recording devices 200 matches the number of self-service drinking water devices 100. Generally, the number of information recording devices 200 is greater than the number of self-service drinking water devices 100.

[0144] In some of these embodiments, the information recording device 200 includes, but is not limited to, RFID electronic ear tags.

[0145] How to use this invention:

[0146] Enter the cattle information into the information recording device 200;

[0147] The information recording device 200 is attached to the corresponding cattle collar or ear tag;

[0148] When the cattle drink water, the pressure sensing unit 170 controls the identification unit 160 to turn on, identify and read the nearest information recording device 200, and record the cattle information.

[0149] The advantages of the present invention are the same as those of Embodiment 1, and will not be repeated here.

The liquid delivery unit 320 is connected to both the liquid storage unit 310 and the drinking water unit 110, and is used to deliver liquid to the drinking water unit 110. The heat preservation unit 330 is located outside the liquid delivery unit 320 to reduce heat loss from the liquid.

[0155] Specifically, the infusion unit 320 is connected to the delivery element 112.

[0156] In some of these embodiments, the liquid storage unit 310 includes, but is not limited to, an insulated water tank.

[0157] The number of infusion units 320 matches the number of self-service drinking water devices 100. Generally, the number of infusion units 320 is equal to the number of self-service drinking water devices 100, that is, there is a one-to-one correspondence between the infusion units 320 and the self-service drinking water devices 100.

[0158] In some of these embodiments, the infusion unit 320 includes, but is not limited to, PVC water pipes.
