Technical Field

[0001] The utility model relates to the technical field of poultry breeding, in particular to an automatic water feeder. Background Art

[0002] Generally, a watering device for feeding poultry is installed in a breeding farm. Most of the watering devices require human intervention and need to add water manually regularly, which is troublesome to operate. Currently, there are some watering devices on the market that can automatically replenish water. The water tray of the watering device is always filled with water. In order to feed water to multiple birds at the same time, the water in the water tray has a large contact area with the air, and the water evaporates quickly at normal times, which easily wastes water resources. In addition, too much stored water exposed to the outside is prone to breed bacteria, mosquitoes and flies. After the contaminated water is drunk by the poultry, the poultry is prone to get sick, causing economic losses to the breeding farm.

[0003] At present, there is no poultry water feeding device that can provide drinking water in a timely, reasonable and appropriate amount according to the needs of poultry for drinking water, as well as the number and weight of drinking poultry, so as to provide drinking water according to the amount of water the poultry drinks, and the more poultry drink, the more water is given, so as to ensure the freshness of the water and avoid waste. Utility Model Content

[0004] The utility model aims to provide an automatic water supply device, which can supply water in time and in appropriate amount according to the water demand of poultry, so as to supply water according to the amount of water the poultry drinks and not supply water if the poultry does not drink, thereby ensuring the freshness and health of the drinking water of the poultry and avoiding the long-term exposure of the drinking water of the poultry to the outside, causing pollution and waste.

[0005] The utility model comprises a water trough, wherein water feeding trays are symmetrically arranged on the side walls on the left and right sides of the water trough, an overflow port is arranged above the water feeding tray, a pedal is arranged below the water feeding tray, a reset spring is fixedly arranged below the pedal, the pedal is fixedly connected to a floating rod, the end of the floating rod extends into the water trough and is connected to a float block; the water trough is connected to a water tank through a connecting pipe, a water inlet pipe is fixedly sleeved on the top of the water tank, a water inlet is arranged at one end of the water inlet pipe located in the water tank, a support rod is fixedly installed at the bottom of the inner cavity of the water tank, a middle part of a lever is rotatably connected to the support rod, a floating ball is fixedly installed at one end of the lever, the other end of the lever is hinged to one end of a connecting rod, the other end of the connecting rod passes through the water inlet and a sealing plug is fixedly installed.

[0006] Preferably, a rotating shaft is provided in the middle of the lever, and the rotating shaft is fixed on the supporting rod.

[0007] Preferably, the water inlet and the sealing plug are matched frustum structures, and the diameter of the frustum close to the connecting rod is smaller than the diameter of the end away from the connecting rod.

[0008] Preferably, the floating block is cylindrical and is disposed transversely in the water tank.

[0009] Preferably, water blocking plates are provided at the left and right ends of the water feeding tray.

[0010] Preferably, a water inlet valve is installed on the water inlet pipe.

[0011] In summary, the utility model has the following beneficial effects:

[0012] 1. The float in the water tank always floats on the water surface. The water level in the water tank is controlled by the lever and the sealing plug, so that the water level in the water tank remains fixed. At the same time, the water tank forms a communicating vessel with the water tank through the connecting pipe. The water level in the water tank is equal to the water level in the water tank, so that the water tank is automatically replenished, the water level in the water tank is kept constant, and automatic water supply is realized;

[0013] 2. A pedal is provided under the water feeding tray, which is fixedly connected to a floating rod. The end of the floating rod extends into the water tank and is connected to a floating block. A reset spring is provided at the bottom of the pedal, and a support spring is also provided at the lower part of the floating rod. The reset spring and the support spring bear the gravity of the pedal and the floating rod, so that the floating block is suspended above the water surface of the water tank. When poultry come to get water, they step on the pedal. Under the action of the gravity of the poultry, the pedal moves down, driving the floating rod and the floating block to move down, and the floating block gradually sinks into the water. The water surface rises, and water overflows from the overflow port for the poultry to drink. When the poultry finishes drinking water and leaves, the pedal does not move. Under the action of the return spring and the support spring, the pedal and the floating rod move up, driving the floating block to move above the water surface, and no water comes out of the overflow outlet; the more birds stand on the pedal and the heavier the birds are, the more the floating block sinks and the more water overflows, and vice versa. In this way, water can be automatically given according to the number and size of the birds, and the amount of water given is determined by how much they drink, ensuring that the birds drink enough water and that there is almost no excess water in the water feeding tray, avoiding long-term water storage in the water feeding tray and evaporation causing waste, and at the same time avoiding the undrunk water in the water feeding tray from being contaminated and then being drunk by the birds again, causing the birds to become infected with bacteria and become sick.

They only represent relative position relationships, not absolute position relationships.

[0019] like Figures 1 to 3 As shown together, an automatic water feeder includes a water trough 1, and water feeding trays 2 are symmetrically arranged on the side walls on the left and right sides of the water trough 1. The cross-section of the water feeding tray 2 is an approximately "C"-shaped structure with an opening facing upward. One side is fixedly connected to the side wall of the water trough 1 to form a downwardly inclined slope to facilitate water to flow into the water feeding tray 2, and the other side is provided with an arc chamfer to facilitate poultry to take water; an overflow port 3 is provided above the water feeding tray 2, and a pedal 4 is provided below the water feeding tray 2. A return spring 5 is fixedly provided below the pedal 4, one end of the return spring 5 is connected to the bottom of the pedal 4, and the other end is fixedly arranged on the ground, and a plurality of return springs 5 ​​are evenly distributed below the pedal 4; one end of the pedal 4 extends to the side of the water trough 1 and is fixedly connected to a floating rod 6, which extends upward, and its end extends into the water trough 1 and is connected to the ground. The lower part of the floating block 7 and the floating rod 6 is located at the side wall of the water tank 1, and a supporting spring 19 is also provided; the water tank 1 is connected to the water tank 8 through the connecting pipe 18, and the water tank 8 and the water tank 1 form a communicating vessel, and the liquid level between the two is kept consistent; the reset spring 5 and the supporting spring 19 bear the gravity of the pedal 4 and the floating rod 6, so that the floating block 7 is suspended above the water surface of the water tank 1. When poultry comes to get water, they step on the pedal 4. Under the action of the gravity of the poultry, the pedal 4 moves down, driving the floating rod 6 and the floating block 7 to move down, and the floating block 7 gradually sinks into the water, the water surface rises, and water overflows from the overflow port 3 for the poultry to drink; when the poultry finishes drinking the water and leaves, the pedal 4 is not subjected to force, and under the action of the reset spring 5 and the supporting spring 19, the pedal 4 and the floating rod 6 move up, driving the floating block 7 to move above the water surface, and no water flows out of the overflow port 3.

[0020] The top of the water tank 8 is fixedly sleeved with a water inlet pipe 9, on which a water inlet valve 20 is installed, and one end of the water inlet pipe 9 located in the water tank 8 is provided with a water inlet 10, and a support rod 11 is fixedly installed at the bottom of the inner cavity of the water tank 8, and the support rod 11 is rotatably connected to the middle part of a lever 12, and a rotating shaft 16 is provided in the middle part of the lever 12, and the rotating shaft 16 is fixed on the support rod 11, and the lever 12 rotates up and down around the support rod 11; a float 13 is fixedly installed at one end of the lever 12, and the other end of the lever 12 is hinged to one end of a connecting rod 14, and the other end of the connecting rod 14 passes through the water inlet 10 and is fixedly installed with a sealing plug 15; the water inlet 10 and the sealing plug 15 are matched frustum structures, and the diameter of the end of the frustum close to the connecting rod 14 is smaller than the diameter of the end away from the connecting rod 14.

[0021] The float 13 is a hollow ball. When the water level in the water tank 8 drops, the float 13 presses down the lever 12 under the action of gravity. The other end of the lever 12 pushes the connecting rod 14 to move the sealing plug 15 upward. The water inlet pipe 9 adds water to the water tank 8 through the water inlet 10. After the water level in the water tank 8 rises, the float 13 floats up and pushes the lever 12. The lever 12 pulls down the sealing plug 15 through the connecting rod 14. The sealing plug 15 blocks the water inlet 10, so that the water level in the water tank 8 remains fixed.

[0022] Furthermore, the floating block 7 is cylindrical, hollow, and made of lightweight material. It is transversely disposed in the water tank 1 , and the length of the floating block 7 is smaller than the length of the water tank 1 .

[0023] Furthermore, water blocking plates 17 are provided at the left and right ends of the water feeding tray 2 to prevent the water in the water feeding tray 2 from flowing out from the two ends.

[0024] Furthermore, in order to prevent water from evaporating and causing waste, a sealing cover is provided on the top of the water tank 1 and the water tank 8, and a vent hole connected to the atmosphere is provided on the sealing cover.

[0025] Working principle: When the utility model is used, in the initial state, the floating block 7 is suspended above the water surface of the water tank 1, the water level in the water tank 1 is the same as the water level in the water tank 8, and is flush with the lower surface of the overflow port 3, the water just does not overflow, and there is no water in the water feeding tray 2; when poultry comes to get water, they step on the pedal 4, and under the action of the gravity of the poultry, the pedal 4 moves down, driving the floating rod 6 and the floating block 7 to move down, the floating block 7 gradually sinks into the water, the water surface rises, and water overflows from the overflow port 3 for the poultry to drink. The more poultry standing on the pedal 4 and the heavier the poultry, the more the floating block 7 sinks and the more water overflows, and vice versa. In this way, Water is automatically supplied according to the number and size of the poultry. The amount of water supplied is determined by the amount of water the poultry drinks, ensuring that the poultry drinks enough water and that there is almost no excess water in the water feeding tray 2, thereby avoiding long-term storage of water in the water feeding tray 2 and waste caused by evaporation. At the same time, it is also avoided that the unfinished water in the water feeding tray 2 is contaminated and then the poultry drinks it again, causing the poultry to be infected with bacteria and become sick. When the poultry has taken all the water, it leaves the pedal 4. Under the action of the reset spring 5 and the support spring 19, the pedal 4 and the floating rod 6 move upward, driving the floating block 7 to move above the water surface. At this time, the water level in the water tank 1 is lower than the water tank 8. The water tank 8 replenishes the water tank 1 with water, so that its water level is always maintained at the lower plane of the overflow port 3.
