A feed uniform blending device for experimental animal feeding

Abstract

This utility model discloses a device for uniformly mixing feed for laboratory animals, including a uniform mixing component. The uniform mixing component includes a shaft, a stirring rod, a receiving circular plate, and a conical cylinder. The shaft is movably connected to the cylinder, and the stirring rod is fixedly connected to both sides of the shaft. The receiving circular plate is movably connected to the bottom end of the stirring rod, and the receiving circular plate is movably connected to the bottom end of the cylinder. The conical cylinder is movably connected to the bottom of the receiving circular plate. This utility model eliminates the gap between the stirring rod and the inner wall of the bottom end of the cylinder, preventing the formation of a "mixing blind zone" at the bottom of the cylinder. This prevents the sedimentation of larger or denser raw materials, ensuring that the raw materials fully participate in the mixing, improving the quality of the formulated feed, and avoiding deviations in component ratios between different batches of feed due to the mixing of residual raw materials, thus ensuring the consistency of experimental data.

Description

Technical Field

[0001] This utility model relates to the field of laboratory animal husbandry technology, specifically to a device for uniformly dispensing feed for laboratory animals. Background Technology

[0002] In laboratory animal husbandry, the uniformity of feed directly affects the accuracy and repeatability of experimental data.

[0003] A search of Chinese patent CN 207941466U, "A Device for Uniformly Mixing Feed for Laboratory Animals," reveals that the device includes a frame. A first mixing tank is positioned above the frame, and a second mixing tank is positioned below it. The first mixing tank is tilted above the frame, and a first stirring shaft, located at the center of the tank, is tilted at the same angle as the tank. Multiple feed pipes are connected to the lower side of the first mixing tank at varying heights. The second mixing tank is vertically positioned below the frame, with a second stirring shaft horizontally positioned at its center. A feed inlet is located at the top of the second mixing tank, and the ends of the feed pipes not connected to the first mixing tank are connected to the feed inlet. This invention effectively improves mixing efficiency and ensures sufficient consistency in the composition of feed mixed in the same batch.

[0004] In existing technologies, a certain gap is created between the stirring rod and the inner wall of the bottom of the mixing tank, which can easily lead to the formation of a "mixing blind zone" at the bottom of the mixing tank. Raw materials with larger or higher density particles (such as grains and mineral particles) tend to settle here and cannot participate in the overall mixing, thus affecting the quality of the formulated feed. Furthermore, when residual raw materials are mixed with new batches of feed, it can cause deviations in the composition ratio between different batches, affecting the consistency of experimental data. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0041] Working principle: Different types of experimental animal feed are added into the cylinder 101 through the feed pipe 104. After the motor 103 is started, it drives the shaft 201 to rotate. The stirring rods 202 on both sides of the shaft 201 rotate synchronously to stir the feed in the cylinder 101. After the feed is stirred, it enters the conical cylinder 204. Then, the valve 206 is opened, and the mixed feed is discharged from the discharge pipe 205 through the conical cylinder 204 to avoid feed accumulation.

[0042] Please see Figure 1-5 As shown, this embodiment, based on the above embodiment, further includes:

[0043] The flexible feeding component includes a circular hole 301, a circular groove 302, and a cylindrical rod 303. The circular hole 301 is opened through the circular plate 203, and the circular groove 302 is opened on the cylinder 101. The cylindrical rod 303 is fixedly connected to the top of the conical cylinder 204. The cylindrical rod 303 movably passes through the circular hole 301 and the circular groove 302. The cylindrical rod 303 is located above the support base 105.

[0044] The circular hole 301, the circular groove 302, and the cylindrical rod 303 work together to ensure the rotation of the circular plate 203, thereby ensuring that the feed after mixing in the cylinder 101 enters the conical cylinder 204.

[0045] The flexible feeding assembly also includes a pull block 304 and an external block 305. The pull block 304 is fixedly connected to the side of the receiving circular plate 203, and the external block 305 is fixedly connected to the top side of the cylinder 101 and the top side of the conical cylinder 204.

The stirred feed enters the conical cylinder 204 from the cylinder 101. At this time, the circular hole 301 on the receiving circular plate 203 is aligned with the circular groove 302 on the cylinder 101. The cylindrical rod 303 at the top of the conical cylinder 204 passes through the circular hole 301 and the circular groove 302, providing support and guidance for the rotation of the receiving circular plate 203. At this time, the pad 309 is moved so that it passes through the vertical block 308 and is supported between the bottom of the cylinder 101 and the top of the conical cylinder 204 to prevent the cylinder 101 from tilting.
