A watering tank circulating assembly includes a frame that is submerged in a livestock watering tank. A fluid pump is coupled to the frame to circulate the water in the livestock watering tank when the fluid pump is turned on. In this way the fluid pump inhibits the water from freezing. A heating coil is coupled to the frame to heat the water when the heating coil is turned on, thusly inhibiting the water from freezing. A thermostatic switch is coupled to the frame and each of the fluid pump and the heating coil is electrically coupled to the thermostatic switch. The thermostatic switch turns on each of the fluid pump and the heating coil when the temperature of the water drops below a trigger temperature. Additionally, the thermostatic switch turns off each of the fluid pump and the heating coil when the temperature of the water rises about the trigger temperature.

An animal feeder comprising a housing, at least one food receptacle coupled to the housing, configured to receive and store food and comprising an inlet opening for receiving food and an outlet opening for releasing food, at least one supplement receptacle coupled to the housing, configured to receive and store at least one supplement, a food dispensing mechanism coupled to the at least one food receptacle, configured to dispense food, a supplement dispensing mechanism coupled to the at least one supplement receptacle and configured to dispense supplement from the at least one supplement receptacle, a control system coupled to the housing and connected to the food and supplement dispensing mechanisms, the control system configured to control the food and supplement dispensing mechanisms so that a desired amount of food and supplement are dispensed, and a power source coupled to the control system and the food and supplement dispensing mechanisms.

A double tank milk supply system for providing a continuous supply of cool clean milk or milk products. While one tank provides milk products, the other tank is cleaned. The two tanks are individually cooled, and the washing and cooling cycles are automatically controlled via a data input and display device. Included is an automatic valve system configured to dispense milk product from the second tank when the first tank is empty, and to dispense milk product from the first tank when the second tank is empty. An automatic washing system automatically washes the first tank when the first tank is empty, and washes the second tank when the second tank is empty. Also included is an agitation system, which alternatingly agitates the milk product in the first or second tank. The double tank milk supply system provides uninterrupted cool, clean milk products 24/7/365, saving the farmer time and labor.

A rearing cage unit is where an animal is reared individually in an environment at least including a space environment. The rearing cage unit includes an animal residential area that is defined by a floor, a ceiling, and a wall; an excrement collection area that is provided adjacently to the animal residential area; and an excretion sheet that is provided in the excrement collection are to receive excrement of the animal. At least one of the floor and the wall is made of a material including resin, and has an excretion hole that allows the excrement in the animal residential area to be discharged to the excrement collection area, and that has a size that prevents four feet of the animal from entering the excretion hole. The excretion sheet is provided facing the excretion hole.

The application belongs to the technical field of pet equipment, in particular to a pet water dispenser, comprising a filter, a water pump, a drinking dish and a water storage tank with a water storage space; the drinking dish is provided with a water storage sink and a first through hole communicating with the water storage sink, the water pump and the filter are both installed on the water storage tank, and the drinking dish covers the water storage tank; a water inlet of the water pump is communicated with the water storage space, a water outlet of the water pump is communicated with the water storage sink, and the first through hole is communicated with the water storage space through the filter; the water pump, the water storage sink, the first through hole, the filter and the water storage space form a circulating filtration loop for drinking water.

A water feeder filter water feeder includes a water storage tank and a water drinking portion. The filter supplies and returns water from the water storage tank to the water drinking portion. The filter is detachably provided between the water storage tank and the water drinking portion and passes the water from an upper surface side to a lower surface side of the filter. The filter includes a filter tray with a bottom wall having a water passing aperture and an outer peripheral wall. An internal filter medium is in the filter tray. A top covering filter medium covers an upper end opening of the filter tray. A partition wall of the filter tray is formed with a lower side is positioned inner than an upper side when viewed from each chamber. The outer peripheral wall is formed with a lower side is positioned inner than an upper side.

Animal drinking troughs have pressure reducers for reducing the higher pressure of the liquid supply to a low liquid pressure for supplying the animal drinking troughs. For various reasons, it is desired to change the reduced pressure. This takes place by adjustment of the pressure reducers. It is known to undertake such an adjustment with compressed air. This requires a separate compressed air source and a corresponding pipe system. The invention makes provision to adjust the pressure reducer hydraulically by means of the higher pressure of the liquid of the liquid supply. The energy required for adjusting the pressure reducers thereby provides the liquid pressure of the liquid supply. As a result, the pressure reducers according to the invention operate autonomously. A separate energy source for adjusting the pressure reducers is not required.

There is provided a liquid supply apparatus eliminating the need for a power supply, having relatively light weight and small footprint, and ensuring a stable liquid supply. The liquid supply apparatus includes a first support member, a second support member, a balloon having one end supported by the first support member and the other end supported by the second support member, and a casing having a constant longitudinal length. The balloon is disposed in the casing and is configured so as to be able to hold a liquid therein and discharge the liquid therefrom. When the balloon holds the liquid, the one end and the other end of the balloon are positioned in the case.
