Description

Technical Field

[0001] This utility model belongs to the technical field of mixed production devices, specifically a mixed production device for laboratory animal feed. Background Technology

[0002] In long-term experiments on laboratory animals, it is sometimes necessary to test the effects of different feed composition ratios on the animals, such as in a weight gain experiment on domestic pigs. However, since domestic pigs have a large appetite, manually mixing the feed would be time-consuming. Therefore, a mixing production device is needed to mix the feed to ensure even distribution. However, conventional mixing production devices typically use a motor to drive a stirring rod on a stirring shaft. Due to the limited stirring range of the stirring shaft, feed tends to accumulate around the inner wall of the device, and even mixing takes time. Therefore, this technical problem needs to be solved. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a mixing production device for laboratory animal feed, which effectively solves the problem that conventional mixing production devices generally use a motor to drive the stirring rod on the stirring shaft for mixing. Due to the limited stirring range of the stirring shaft, the feed tends to accumulate around the inner wall of the device, and uniform mixing takes a certain amount of time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mixing production device for laboratory animal feed, comprising a mixing tank, a mixing mechanism disposed within the mixing tank, the mixing mechanism comprising a driving component, a hollow shaft, hollow stirring rods, and auxiliary components, the driving component being fixedly disposed on the mixing tank and providing power to the hollow shaft, the hollow shaft being rotatably disposed within the mixing tank, and multiple hollow stirring rods being disposed and fixedly disposed on the hollow shaft; the auxiliary components comprising a fixed shaft and multiple stirrers cooperating with the fixed shaft, wherein the fixed shaft is fixedly disposed within the mixing tank by multiple fixing brackets, the hollow shaft being rotatably disposed outside the fixed shaft, and a stationary bevel gear being fixedly disposed on the fixed shaft, the stirrers being rotatably disposed within corresponding hollow stirring rods, and a moving bevel gear being fixedly disposed on the stirrers, the moving bevel gear meshing with the stationary bevel gear.

[0005] Preferably, the driving component includes a drive motor, a driving gear, and a driven gear, wherein the drive motor is fixedly mounted on the mixing tank, the driving gear is fixedly mounted on the output shaft of the drive motor, and the driven gear is fixedly mounted on a hollow shaft and meshes with the driving gear.

[0006] Preferably, the radius of the driving gear is smaller than the radius of the driven gear.

[0007] Preferably, a mounting bracket is fixedly provided at the top of the mixing tank. The mounting bracket is U-shaped and is fixedly provided with a fixed shaft.

[0008] Preferably, the stirrer includes a moving bevel gear, a connecting rod, and a stirring frame, wherein the moving bevel gear is fixedly mounted on the connecting rod at the end near the fixed shaft, the connecting rod is rotatably mounted inside the hollow stirring rod, and the stirring frame is fixedly mounted on the connecting rod at the end away from the fixed shaft.

[0009] Preferably, the mixing tank is provided with connecting springs and support rings on its outer side. The mixing tank is fixedly mounted to the inner wall of the support ring by multiple connecting springs distributed along its circumference. Multiple support frames are fixedly mounted on the support ring.

[0010] Preferably, a vibrating column is fixedly mounted on the hollow shaft, and the rotation axis of the vibrating column is eccentrically positioned relative to the rotation axis of the hollow shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. During operation, by using the auxiliary components in the mixing mechanism, the feed can be mixed around the inner wall of the mixing tank by the agitator in the auxiliary components during the mixing process of the hollow mixing rod, so as to further improve the mixing rate of the feed.

[0013] 2. During operation, through the cooperation of the connecting spring and the vibrating column, the hollow shaft rotates, which in turn drives the vibrating column to rotate. Due to the eccentric setting of the rotating column, in the rotating state, in conjunction with the setting of the connecting spring, the eccentric force can cause the mixing tank to vibrate, thereby further enhancing the mixing rate of the feed.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figure 1-5 The present invention relates to a mixing production device for laboratory animal feed, comprising a mixing tank 1, a mixing mechanism provided inside the mixing tank 1, the mixing mechanism comprising a driving component, a hollow shaft 2, and hollow stirring rods 3, the driving component being fixedly mounted on the mixing tank 1 and providing power to the hollow shaft 2, the hollow shaft 2 being rotatably mounted inside the mixing tank 1, and multiple hollow stirring rods 3 being provided and all being fixedly mounted on the hollow shaft 2;

[0024] During operation, the outlet of mixing tank 1 is closed, and animal feed is put into the interior of mixing tank 1 through the inlet. The hollow shaft 2 is driven to rotate by the drive component, and the hollow shaft 2 drives the hollow stirring rod 3 on it to rotate. The hollow stirring rod 3 mixes different feeds to make the feed evenly distributed. The above is the prior art, so it will not be described in detail.

[0025] To further improve the mixing rate of the feed, the mixing mechanism also includes auxiliary components, including a fixed shaft 4 and multiple agitators that cooperate with the fixed shaft 4. The fixed shaft 4 is fixedly installed in the mixing tank 1 by multiple fixing brackets 5. The hollow shaft 2 is rotatably installed on the outside of the fixed shaft 4, and a stationary bevel gear 6 is fixedly installed on the fixed shaft 4. The agitators are rotatably installed in the corresponding hollow stirring rods 3, and a moving bevel gear 7 is fixedly installed on the agitators. The moving bevel gear 7 meshes with the stationary bevel gear 6.

[0026] With this design, as the hollow stirring rod 3 rotates, it drives the internal agitator to move, causing the moving bevel gear 7 on the agitator to rotate around the stationary bevel gear 6 on the fixed shaft 4. This causes the agitator to rotate, and while the hollow stirring rod 3 mixes the feed in the middle of the mixing tank 1, it also drives the agitator to mix the feed around the inner wall of the mixing tank 1, thereby accelerating the mixing range and further improving the mixing rate.

[0027] Specifically, the driving components include a drive motor 8, a driving gear 9, and a driven gear 10. The drive motor 8 is fixedly mounted on the mixing tank 1, the driving gear 9 is fixedly mounted on the output shaft of the drive motor 8, and the driven gear 10 is fixedly mounted on the hollow shaft 2 and meshes with the driving gear 9. The radius of the driving gear 9 is smaller than the radius of the driven gear 10. With this design, the drive motor 8 drives the driving gear 9 to rotate, the driving gear 9 drives the driven gear 10 to rotate through meshing, and the driven gear 10 drives the hollow shaft 2 to rotate, thus realizing the driving process.

[0028] Specifically, a mounting bracket 11 is fixedly installed at the top of the mixing tank 1. The mounting bracket 11 is U-shaped and is fixedly installed with the fixed shaft 4. This design facilitates the installation of the fixed shaft 4 by using the mounting bracket 11 to further enhance its strength and improve its stability.

[0029] Specifically, the agitator includes a moving bevel gear 7, a connecting rod 12, and a mixing frame 13. The moving bevel gear 7 is fixedly mounted on the connecting rod 12 near the end of the fixed shaft 4. The connecting rod 12 is rotatably mounted inside the hollow mixing rod 3. The mixing frame 13 is fixedly mounted on the connecting rod 12 away from the fixed shaft 4. With this design, when the moving bevel gear 7 moves around the stationary bevel gear 6, it drives the mixing frame 13 to rotate through the connecting rod 12, and the mixing frame 13 performs a mixing operation on the feed around the inner wall of the mixing tank 1.

[0030] Furthermore, the mixing tank 1 is provided with connecting springs 14 and support rings 15 on its outer side. The mixing tank 1 is fixed to the inner wall of the support ring 15 by multiple connecting springs 14 distributed along its circumference. Multiple support frames 16 are fixedly provided on the support ring 15. A vibrating column 17 is fixedly provided on the hollow shaft 2. The rotation axis of the vibrating column 17 is eccentrically set relative to the rotation axis of the hollow shaft 2. With this design, when the hollow shaft 2 rotates, it also drives the vibrating column 17 to rotate. Since the vibrating column 17 is eccentrically set, in the rotating state, in conjunction with the setting of the connecting springs 14, the mixing tank 1 can be vibrated by the eccentric force to further enhance the mixing rate of the feed.
