Description

Technical Field

[0001] The invention relates to the technical field of mixing devices, in particular to a device for uniformly mixing feed for experimental animals. Background Art

[0002] The experimental animal feed uniform mixing device is a device specially used to uniformly mix and mix the feed raw materials required by experimental animals. This device plays a vital role in the breeding of experimental animals. It can ensure that the experimental animals obtain nutritionally balanced feed to meet their growth, reproduction and experimental needs.

[0003] At present, some existing experimental animal feed uniform mixing devices only rely on a single rotation stirring method and lack multi-dimensional stirring movement. This single stirring method easily leads to stirring dead corners in the mixing barrel, making it impossible to fully mix the feed in the mixing barrel. In view of this, we propose an experimental animal feed uniform mixing device. Summary of the invention

[0012] Preferably, the through groove is sleeved with a gear sleeve, and the gear sleeve is meshed with the rack. Through the meshing of the gear sleeve and the rack, the gear sleeve rotates simultaneously during the reciprocating motion. Through the rotation of the gear sleeve, the shaft drives the stirring blade to rotate. The upper end of the inner wall of the gear sleeve is fixedly connected to a bearing, and the inner wall of the bearing is fixedly connected to a sliding block.

[0018] The present invention provides a device for uniformly mixing experimental animal feed, which has the following beneficial effects:

[0019] (1) In the experimental animal feed uniform mixing device, during the rotation of the shaft, the inclined surface sleeve 1 and the inclined surface sleeve 2 will exert a force on the rod body. At this time, the sliding rod will make a reciprocating motion up and down under the action of the rod body, so that the stirring rod will also make a reciprocating motion up and down during the rotation process, thereby improving the mixing effect of the feed. At the same time, during this process, the tooth block on the U-shaped plate fixedly connected to the fixed rod will exert a force on the gear, so that the gear drives the rotating rod to rotate, and then the rotating rod drives the stirring rod to move while rotating, thereby further improving the mixing effect of the feed.

[0020] (2) In the experimental animal feed uniform mixing device, during the rotation of the shaft, the cross bar will drive the gear sleeve to rotate synchronously.

At this time, the arc groove will exert a force on the sliding block, so that the gear sleeve drives the stirring blade to reciprocate in the mixing barrel, thereby improving the mixing effect of the feed. At the same time, through the cooperation between the gear sleeve and the rack, the shaft body slidably connected to the gear sleeve drives the stirring blade to rotate, thereby further improving the mixing effect of the feed.

[0021] (3) In the experimental animal feed uniform mixing device, when the shaft body rotates, the fixed block fixedly connected to the shaft body rotates synchronously. During this process, the annular inclined groove exerts a force on the fixed block, so that the fixed block drives the shaft body to make an up and down reciprocating motion in the rotating sleeve, and then the stirring blades make an up and down reciprocating motion during the rotation process, thereby further improving the mixing effect of the feed.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 9 The present invention proposes a device for uniformly mixing experimental animal feed, including a support frame 1, a mixing barrel 2 is fixedly connected to the inner wall of the support frame 1, an arc groove 21 is fixedly connected to the top of the inner wall of the mixing barrel 2, the arc groove 21 is slidably connected to the sliding block 582, a slope sleeve 1 22 is fixedly connected to the outer wall of the mixing barrel 2, a slope sleeve 23 is arranged above the slope sleeve 1 22, the slope sleeve 23 is fixedly connected to the inner wall of the base 24, a feeding pipe 3 is arranged at the lower end of the mixing barrel 2, a feeding hopper 4 is arranged at the upper end of the mixing barrel 2, and a mixing device 5 is arranged on the mixing barrel 2.

[0037] In the embodiment of the present invention, in order to be able to mix the feed, specifically, the mixing device 5 includes a motor 51, the motor 51 is fixedly connected to the base 24, the base 24 is fixedly connected to the outer wall of the mixing barrel 2, a rotating shaft 52, the rotating shaft 52 penetrates the base 24 and the mixing barrel 2 and is rotatably connected to the base 24 and the mixing barrel 2, the rotating shaft 52 is provided with a notch 521, the notch 521 is slidably connected to a rod body 522, a sliding rod 53, the sliding rod 53 penetrates the rotating shaft 52 and is slidably connected to the inner wall of the rotating shaft 52, the sliding rod 53 is penetrated by the rod body 522 and is fixedly connected to the rod body 522, a ball 54 is fixedly connected to the outer wall of the bottom end of the sliding rod 53, the ball 54 has an inner cavity, the ball 54 is penetrated by the rotating rod 55 and is rotatably connected to the rotating rod 55, and the end of the rotating rod 55 away from the ball 54 is fixedly connected to a stirring rod 56;

[0038] like Figure 4As shown, when the shaft 52 rotates, the rod body 522 slidably connected to the slot 521 rotates synchronously with the shaft 52. During the rotation of the rod body 522, the inclined surface sleeve 23 applies a force to the rod body 522, causing the rod body 522 to move toward a high point along the inclined surface sleeve 23. At this time, the sliding rod 53 fixedly connected to the rod body 522 drives the stirring rod 56 to move upward. When the rod body 522 continues to move, the inclined surface sleeve 1 22 applies a force to the rod body 522. Under the force of the inclined surface sleeve 1 22, the rod body 522 moves toward a low point along the inclined surface sleeve 23. At this time, the sliding rod 53 fixedly connected to the rod body 522 drives the stirring rod 56 to move downward. Therefore, through the design of the inclined surface sleeve 1 22 and the inclined surface sleeve 23, during the rotation of the shaft 52, the sliding rod 53 drives the stirring rod 56 to reciprocate up and down, thereby improving the mixing effect of the feed.

[0039] Furthermore, the sliding rod 53 is penetrated by the fixed rod 531 and is slidably connected to the fixed rod 531. One end of the fixed rod 531 is fixed to the top of the inner wall of the rotating shaft 52. The outer wall of the other end of the fixed rod 531 is fixedly connected to a U-shaped plate 532. A gear block 533 is provided on the inner wall of one side of the U-shaped plate 532. The gear block 533 is meshed with a gear 551. The gear 551 is fixedly connected to the rotating rod 55.

[0040] like Figure 6-Figure 7 As shown, there are two groups of rotating rods 55, and the two groups of rotating rods 55 are fixedly connected by gears 551. When the sliding rod 53 moves upward, the ball 54 fixedly connected to the sliding rod 53 drives the two groups of rotating rods 55 to move upward. Since the position of the fixed rod 531 is fixed, the position of the U-shaped plate 532 fixedly connected to the fixed rod 531 is fixed. At this time, when the rotating rod 55 moves upward, the tooth block 533 designed on the U-shaped plate 532 will start to mesh with the gear 551 and exert force on it, so that the gear 551 rotates. When the gear 551 rotates, the rotating rod 55 fixedly connected to the gear 551 will drive the stirring rod 56 to rotate. When the sliding rod 53 moves downward, similarly, the tooth block 533 will apply force to the gear 551 again, so that the gear 551 drives the rotating rod 55 to rotate in the opposite direction. Therefore, through the design of the fixed rod 531, the U-shaped plate 532, the tooth block 533 and the gear 551, the rotating rod 55 drives the stirring rod 56 to rotate during the up and down reciprocating motion of the sliding rod 53, thereby further improving the mixing effect of the feed.

[0041] Furthermore, the rotating shaft 52 passes through the cross bar 57 and is fixedly connected to the inner wall of the cross bar 57. The cross bar 57 is provided with a through slot 571. A rack 572 is fixedly connected to the outer wall on one side of the cross bar 57. A fixing plate 573 is fixedly connected to the outer wall on the other side of the cross bar 57. The fixing plate 573 is provided with a sliding slot 574. A gear sleeve 58 is sleeved on the through slot 571. The gear sleeve 58 meshes with the rack 572. A bearing 581 is fixedly connected to the upper end of the inner wall of the gear sleeve 58. A sliding block 582 is fixedly connected to the inner wall of the bearing 581.

[0042] Further, a slide groove 580 is provided on the inner wall of the lower end of the gear sleeve 58, the gear sleeve 58 is supported by the shaft body 586 and is slidably connected to the shaft body 586, a protrusion 587 is fixedly connected to the outer wall of the upper end of the shaft body 586, the protrusion 587 is slidably connected to the slide groove 580, a fixed block 588 is provided below the protrusion 587, the fixed block 588 is fixedly connected to the shaft body 586, the gear sleeve 58 passes through the rotating sleeve 583 and is rotatably connected to the rotating sleeve 583, a slider 584 is fixedly connected to the outer wall of the rotating sleeve 583, and the slider 584 is slidably connected to the sliding groove 574;

[0043] Furthermore, the rotating sleeve 583 is penetrated by the shaft 586 and sleeved with the shaft 586. The inner wall of the rotating sleeve 583 is provided with an annular bevel groove 585, and the annular bevel groove 585 is slidably connected with the fixed block 588. The shaft 586 penetrates the stirring blade 589 and is fixedly connected with the inner wall of the stirring blade 589. The stirring blade 589 is provided with multiple groups, and the multiple groups of stirring blades 589 are evenly distributed on the outer wall of the shaft 586.

[0044] In the present invention, when in use, first pour the feed of the experimental pigs into the mixing barrel, then start the motor 51. When the motor 51 is started, the rotating shaft 52 fixedly connected to the output end of the motor 51 drives the sliding rod 53 to rotate. When the sliding rod 53 rotates, the stirring rod 56 rotatably connected to the sliding rod 53 rotates around the rotating shaft 52 as the center, thereby mixing the feed;

[0045] When the rotating shaft 52 rotates, the inclined surface sleeve 1 22 and the inclined surface sleeve 23 will apply a force to the rod body 522, so that the rod body 522 makes a reciprocating motion up and down in the notch 521. At the same time, the rod body 522 will drive the sliding rod 53 to make a reciprocating motion up and down, so that the stirring rod 56 will make a reciprocating motion up and down during the rotation process, thereby improving the mixing effect of the feed. At the same time, when the sliding rod 53 makes a reciprocating motion up and down, the tooth block 533 on the U-shaped plate 532 fixedly connected to the fixed rod 531 will apply a force to the gear 551, so that the gear 551 drives the rotating rod 55 to rotate, and then the rotating rod 55 drives the stirring rod 56 to move while rotating, thereby further improving the mixing effect of the feed;

[0046] During the rotation of the rotating shaft 52, the cross bar 57 fixedly connected to the rotating shaft 52 rotates synchronously. When the cross bar 57 rotates, the cross bar 57 drives the gear sleeve 58 to rotate synchronously. During this process, the sliding block 582 slides in the arc groove 21. Since the arc groove 21 is elliptical and the distance between each point in the arc groove 21 and the rotating shaft 52 is different, the arc groove 21 applies a force to the sliding block 582 during the sliding of the sliding block 582, so that the gear sleeve 58 reciprocates in the through groove 571. When the gear sleeve 58 reciprocates, the shaft body 586 slidably connected to the gear sleeve 58 drives the stirring blade 589 to reciprocate in the batching barrel 2, thereby improving the mixing effect of the feed.

[0047] At the same time, when the gear sleeve 58 reciprocates in the through groove 571, the gear sleeve 58 will mesh with the rack 572. Under the action of the rack 572, the gear sleeve 58 rotates while reciprocating. When the gear sleeve 58 rotates, the shaft 586 slidably connected to the gear sleeve 58 drives the stirring blade 589 to rotate, thereby further improving the mixing effect of the feed.

[0048] When the shaft 586 rotates, the fixed block 588 fixedly connected to the shaft 586 rotates synchronously. During this process, the annular inclined groove 585 exerts a force on the fixed block 588, so that the fixed block 588 drives the shaft 586 to reciprocate up and down in the rotating sleeve 583, and then the stirring blade 589 reciprocates up and down during the rotation process, thereby further improving the mixing effect of the feed. When the feed is mixed, the discharge pipe 3 is opened to discharge the feed from the mixing barrel 2.

[0049] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
