Problems solved by technology

[0003] The number of embryo samples stored in existing liquid nitrogen freezing tanks is limited, and buffalo breeding requires large-scale preservation of embryos, so a large number of liquid nitrogen freezing tanks are required, which takes up a lot of space and is troublesome to manage. The embryos are lifted out of the tank, and the temperature of liquid nitrogen is extremely low. Artificial extraction of embryos may cause danger to the user.

Embodiment 1

[0023] An embryo freezer for buffalo breeding, comprising a fresh-keeping tank 1, the inner wall of the fresh-keeping tank 1 adopts closed-cell foam glass as an insulating material, which can effectively isolate internal and external temperatures, and keep the tank at a long-term low temperature. The fresh-keeping tank 1 is filled with liquid nitrogen, Embryos can be frozen. A first motor 2 is arranged in the center of the upper part of the fresh-keeping tank 1. The first motor 2 is connected to a turret 4 through a rotating shaft 3. The turret 4 is provided with six groups, and there is a gap with the bottom of the fresh-keeping tank 1. The turret 4 can be rotated freely, and the limit rod 5 is vertically installed on the turret 4, and the limit rod 5 is overcoated with a test tube placement tube 6, and the test tube placement tube 6 adopts a foamed plastic material, and the test tube groove 7 is inclined at forty-five degrees, and It is divided into multiple layers, and each ...

Embodiment 2

[0025] An embryo freezer for buffalo breeding, a grabbing head 16 is arranged below the grabbing mechanism 15, a third motor 17 is arranged in the grabbing head 16, a rotating piece 18 is connected to the bottom of the third motor 17, and the rotating piece 18 is opened. There are spiral grooves 19, six sets of bayonet telescopic grooves 20 are arranged below the rotating piece 18, the bayonet telescopic grooves 20 are provided with grasping bayonet pins 21, and the upper part of the grasping bayonet pins 21 is provided with a moving block 22, and the spiral grooves 19 are opened. There are six groups, and the center is symmetrical. The movable block 22 can be matched with the spiral groove 19. When the automatic lifting device 9 descends, the hemispherical grabbing head 16 is inserted into the grabbing groove 26 on the upper end of the test tube placement cylinder 6. At the same time, the third motor 17 drives the rotating piece 18 to rotate counterclockwise, and through the c...

Abstract

The embryo freezing fresh-keeping device comprises a fresh-keeping tank, a first motor is arranged in the center of the upper portion of the fresh-keeping tank, the first motor is connected with a rotating frame, a limiting rod is vertically installed on the rotating frame, the limiting rod is sleeved with a test tube containing cylinder, and an automatic lifting device is arranged on one side of the upper portion of the fresh-keeping tank. A second motor is arranged in the automatic lifting device, a lifting lead screw penetrating through the guide rail groove is connected to the lower portion of the second motor, the lifting lead screw is connected with a grabbing mechanism in a matched mode through a lead screw nut sliding block, a taking-out opening is formed in the portion, below the grabbing mechanism, of the fresh-keeping tank, a threaded sealing cover is installed on the taking-out opening, and an opening-closing rotating disc is welded to the threaded sealing cover. According to the automatic lifting device for the fresh-keeping tank, through the arrangement of the automatic lifting device, the test tube placement barrel in the fresh-keeping tank can be automatically lifted out, manual lifting is omitted, the chance that a user makes contact with liquid nitrogen is reduced, and safety is greatly improved.

Description

technical field [0001] The invention relates to the related technical field of buffalo breeding equipment, in particular to an embryo freezer for buffalo breeding. Background technique [0002] Buffalo is a large-scale draft animal with a domestication history of about 5,000 years. In order to improve the breeding efficiency of buffalo and optimize the breed, most modern large-scale buffalo breeding adopts artificial in vitro fertilization embryo transfer and breeding. For high-quality buffalo individuals, embryo extraction is used to preserve In order to improve its reproductive efficiency, it is necessary to preserve the retained embryos. At present, vitrification is mostly used to preserve living embryos for a long time, and the water molecules in the embryos are replaced with protective agents, and then placed in liquid nitrogen for cryopreservation. [0003] The number of embryo samples stored in existing liquid nitrogen freezing tanks is limited, and buffalo breeding r...
