Description

TECHNICAL FIELD

[0002] Experimental mice are used in biomedical research to construct human disease models, drug screening, toxicology testing, gene function research, and immunology research, and in this process, mouse feed is used to breed and feed experimental mice, and in drug metabolism experiments, the particle size of the mouse feed needs to be controlled to ensure uniform distribution of the drug in the mouse feed carrier, so as to mix the drug and the mouse feed. The experimental mouse feed crushing device is a mechanical device for crushing cylindrical mouse feed eaten by experimental mice and rats into powder or small particles.

[0003] Because the mouse feed is regular cylindrical and the single particle size is large, in order to improve the crushing efficiency and reduce the wear rate of the crushing knife, a pre-crushing roller is usually used to pretreat the mouse feed, and the primary crushing of the mouse feed is realized through the extrusion effect. However, during the extrusion process of the pre-crushing roller, due to the cylindrical characteristics of the mouse feed particles and the large single particle volume, the mouse feed is prone to rolling when it contacts the roller surface, resulting in unintended axial rolling displacement of the mouse feed along the tangential direction of the roller surface, which not only destroys the effective extrusion contact state of the mouse feed, but also causes the mouse feed to move and block, affecting the crushing efficiency of the mouse feed.

[0026] The surface of the stand 410 is sleeved with a moving block 411, the front end of the moving block 411 is fixedly connected with a guide rod 409, the mouse food pushing frame 407 can slide on the surface of the guide rod 409 to guide the moving path, the guide rod 409 is inserted into the inside of the mouse food pushing frame 407, the moving block 411 is fixedly connected with a downward spring 412 between the transverse support beam 405, when the mouse food pushing frame 407 is shaken up and down and moved forward and backward, the rolling shaft 416 is always in contact with the surface of the transverse support beam 405 and the convex block, the surface of the winding shaft 421 is provided with a cavity 422, the cavity 422 is gradually narrowed from top to bottom, the inside of the cavity 422 is slidably connected with a positioning pin 423, the upper surface of the positioning pin 423 is fixedly connected with a downward spring 427, the downward spring 427 can push the positioning pin 423 to be inserted into the rotating shaft 420 again when the winding shaft 421 is rotated at any amplitude.

[0027] The positioning pin 423 is inserted into the inside of the rotating shaft 420, the side surface of the positioning pin 423 is provided with a sliding groove, the inside of the sliding groove on the positioning pin 423 is slidably connected with two side edge supports 424, the side edge supports 424 are fixedly connected with a pushing spring 426 between the positioning pin 423, the pushing spring 426 makes the abutting shaft 425 always abut against the inner wall of the cavity 422, can provide resistance in the process that the positioning pin 423 is inserted into the rotating shaft 420, prolongs the time required for the positioning pin 423 to be inserted into the rotating shaft 420, the positioning pin 423 and the rolling shaft 416 are both made of a magnet, the rolling shaft 416 made of a magnet and the positioning pin 423 are attracted to each other, can drive the positioning pin 423 to be pulled out from the rotating shaft 420, the two side edge supports 424 are rotatably connected with the abutting shaft 425 at the ends away from each other.

[0028] Through the above technical scheme, when the mouse food is crushed, the mouse food is put into the mouse food input hopper 401, and the mouse food can fall between the two pre-rollers 403 through the mouse food input hopper 401, and then the pre-rollers 403 are driven to rotate through the first motor 402, so that the mouse food can be crushed through the rotating pre-rollers 403. In the process of pre-crushing the mouse food, the winding shaft 421 can be driven to rotate through the second motor 406, so that the winding shaft 421 can wind the pull rope 408, and then pull the mouse food pushing frame 407 to move forward. At this time, the reset spring 413 is in a stretched state. When the mouse food pushing frame 407 moves to the end of the transverse support beam 405, the rolling shaft 416 made of a magnet and the positioning pin 423 are attracted to each other, so that the positioning pin 423 can be pulled out of the rotating shaft 420. At this time, the winding shaft 421 can rotate on the surface of the rotating shaft 420. The mouse food pushing frame 407 can be moved backward through the reset spring 413. Since the diameter of the winding shaft 421 is small, the distance moved by the mouse food pushing frame 407 after one rotation of the winding shaft 421 is also short. Therefore, the requirement for the number of rotations of the winding shaft 421 can be reduced without affecting the operation effect.

[0029] During this process, since the cavity 422 is wide at the top and narrow at the bottom, and the pushing spring 426 makes the abutting shaft 425 always abut against the inner wall of the cavity 422, resistance can be provided during the process of pushing the positioning pin 423 into the rotating shaft 420 again after the rolling shaft 416 moves away from the positioning pin 423. The lower pressing spring 427 can prolong the time required for the positioning pin 423 to be inserted into the rotating shaft 420, ensure that the mouse food pushing frame 407 moves backward to the rear end of the transverse support beam 405, and then the positioning pin 423 is inserted into the rotating shaft 420 again to pull the mouse food pushing frame 407 to move forward again. The mouse food pushing frame 407 can move back and forth quickly. When the mouse food pushing frame 407 moves back and forth, the rolling shaft 416 rolls on the surface of the transverse support beam 405. The mouse food pushing frame 407 can be shaken up and down through the protrusion, so that the mouse food can be lifted up while being dredged. The situation that part of the mouse food is only pushed and cannot be dredged is avoided, and the dredging effect is improved.

[0033] In the process of crushing the mouse food, the mouse food in the crushing bin 3 can be heated by the heating sheet 511 to reduce the water content in the mouse food, so as to avoid the caking of the mouse food in the process of crushing and after the crushing is completed, and to affect the uniformity of the subsequent drug mixing. When the water in the mouse food is dried, the air with high water content in the crushing bin 3 can be extracted by the air suction fan 510, so as to further improve the drying effect, and the air can be sucked into the dust collecting cylinder 508, so that the air mixed with the mouse food powder rotates and flows in the dust collecting cylinder 508. The mouse food powder gradually falls due to the inertia generated by the rotation and the friction with the inner wall of the dust collecting cylinder 508, so that the mouse food powder is separated from the air, and the air is prevented from carrying the mouse food powder out through the exhaust pipe 507.
