This utility model relates to the field of egg collection technology and discloses an egg collection device for breeding chickens. It includes an installation chamber with a conveyor belt rotatably mounted inside. A deceleration component is installed on the top of the installation chamber near the chicken cage, and an anti-detachment component is installed on the top of the installation chamber away from the deceleration component. This egg collection device for breeding chickens effectively reduces the rolling speed of eggs by applying negative pressure suction when they fall onto the collection device, significantly reducing the momentum when the eggs impact the conveyor belt. Combined with a specially designed elastic soft pad as a contact surface, it can fully absorb and disperse the remaining impact energy. This deceleration and soft landing solves the industry pain point of egg breakage due to high-speed impact in traditional inclined roll-down collection devices, achieving lossless egg collection and bringing significant economic benefits.

The utility model relates to a water outlet mute mechanism of a water inlet valve, a valve body of the water inlet valve is provided with a water outlet, a circumferential flow dividing piece communicated with the water outlet is arranged below the water outlet, and a spiral flow guiding piece is arranged below the circumferential flow dividing piece; the circumferential flow dividing piece is provided with a water retaining disc connected with a plurality of flow dividing ribs, water flow flowing down from the water outlet is divided by the flow dividing ribs, then is blocked by the water retaining disc and falls down around the inner wall of the water outlet pipe, and the falling water flow is spirally guided into rotating water flow through spiral blades of the spiral flow guiding piece and flows out downwards. The device has the advantages that water flow generates rotation to buffer water outlet impulsive force, and the noise reduction effect and the mute effect are achieved.

This invention discloses a vortex water tank with a constant temperature extrusion die, comprising a tank body, end plates fixed to both ends of the tank body, a sealing plate dividing the inner cavity of the tank into a vacuum section and a non-vacuum section, a top cover rotatably connected to the top of the tank body, and a sealing seat disposed in the non-vacuum section. The sealing seat has a through hole for the profile to pass through, and a water seal structure for forming a dynamic water seal is provided in the through hole. It also includes an extension cover, fixedly connected to the side of the sealing seat near the non-vacuum section, with its end rotatably connected to the sealing plate via a rotating shaft. By automatically releasing the sealing plate and opening the channel, the profile head can be smoothly output under the protection of the formed complete water seal. This avoids poor profile head shaping, dimensional fluctuations, and surface defects caused by insufficient vacuum or incomplete water seal establishment, thereby minimizing the waste length during startup and significantly improving material utilization and startup yield.
