Embodiment 1

[0031] Such as figure 1 As shown, the granulation device for the specially formulated feed for experimental animals includes an upper body 1 and a lower body 2 .

[0032] The upper body 1 includes an upper supporting surface 11 and a plurality of closed cylinders 12, the upper ends of which are fixedly connected to the surface of the upper supporting surface 11, and the dimensions of the plurality of closed cylinders 12 are the same.

[0033] The lower body 2 includes a lower supporting surface 21 and a plurality of semi-closed cylindrical sleeves 22, the lower ends of the plurality of semi-closed cylindrical sleeves 22 are fixedly connected to the surface of the lower supporting surface 21, and the plurality of semi-closed cylindrical sleeves 22 are the same size. The position of the lower supporting surface 21 corresponding to the semi-closed cylindrical sleeve 22 is hollow. Both the upper supporting surface 11 and the lower supporting surface 21 can use transparent plates...

Embodiment 2

[0038] Such as figure 2As shown, on the basis of the structure of the granulation device of the experimental animal feed in Example 1, the lower surface of the disc device 23 is connected to the piston type push rod 24, and the piston type push rod 24 includes a piston 241 and a push rod connected by a connecting rod 242. Rod 243, the piston is set in the semi-closed cylindrical sleeve 22 and supported by the receiving edge 25, and the push rod is arranged below the receiving edge 25 of the semi-closed cylindrical sleeve 22, and the wafer can be moved by pushing the piston-type push rod 24. The device 23 freely moves up and down in the semi-closed cylindrical sleeve 22 .

Embodiment 3

[0040] Such as image 3 As shown, on the basis of the structure of the granulation device for the special feed for experimental animals in Example 2, it also includes an upper force applying device 5 , a lower force applying device 3 and a controller 4 .

[0041] The upper force application device 5 includes an upper force application arm 51 and a plurality of upper connecting columns 53, the lower surface of the upper force applying arm 51 is connected at the center position of the upper surface of the upper supporting surface 11, and the upper ends of the plurality of upper connecting columns 53 are connected On the upper force applying arm 51, the lower ends of a plurality of upper engaging columns 53 are respectively connected to the upper surface of the upper supporting surface 11, and the lower ends of the plurality of upper engaging columns 53 are symmetrical at the connection points of the upper supporting surface 11, so that the upper When the force-applying arm 51 pu...

Abstract

The invention discloses a granulating device for special feed for experimental animals. The device comprises an upper main body and a lower main body, the upper main body comprises an upper bearing surface and a plurality of closed cylinders, the lower main body comprises a lower bearing surface and a plurality of semi-closed cylindrical sleeves, the semi-closed cylindrical sleeves are not provided with upper bottom surfaces, the plurality of closed cylinders can be embedded into the plurality of semi-closed cylindrical sleeves, and an upper force application device can push the upper main body to move upwards or downwards. A wafer device is arranged in the semi-closed cylindrical sleeve, the lower surface of the wafer device is connected with a piston type push rod, the piston type push rod is pushed to enable the wafer device to move up and down in the semi-closed cylindrical sleeve, and a lower force application device can push the piston type push rod to move upwards in the semi-closed cylindrical sleeves. The upper force application device and the lower force application device are controlled by a controller, and can automatically adjust the length of the granules and the quantity of the granules to be prepared.

Description

technical field [0001] The invention belongs to the field of animal equipment, and in particular relates to a granulation device for specially formulated feed for experimental animals. Background technique [0002] At present, experimental animals occupy an important position in biological and medical research, and play an important role in the evaluation of some drugs, ingredients and additives. At present, the evaluation of drugs, ingredients and additives is mostly done by gavage, but this process will cause damage to the gastrointestinal tract and mucous membrane of experimental animals, and in severe cases, it will cause stress and even death of experimental animals. Evaluation performance has a negative impact. Secondly, in the face of some larger and more ferocious experimental animals, experimenters are often injured when performing this process. In addition, in addition to this method, some experimenters add the required formula to the feed. However, the scale of ...
