[0002] In the scientific research of experimental animals, as one of the most commonly used model organisms, the nutritional proportion of mouse feed directly affects the accuracy of experimental results and the health status of animals. At present, the common method for proportioning mouse feed in laboratories mainly relies on manual weighing and manual mixing, and there are many defects in this traditional method. On the one hand, the accuracy of manual weighing is easily affected by subjective factors of operators, and it is difficult to meet the requirements of precise proportioning of trace components such as vitamins and minerals in feed for experiments, which may lead to unbalanced feed nutrition and then interfere with the reliability of experimental data. On the other hand, for feed containing multiple raw materials, manual mixing is difficult to ensure uniform distribution of each component, and it is easy to have situations where the local concentration is too high or too low, affecting the feeding and nutrient absorption of mice. With the continuous improvement of the requirements for standardization and automation of experimental animals, the traditional manual proportioning method has gradually been unable to meet the needs of modern scientific research. Although some automated feed proportioning devices have also appeared in the prior art, these devices generally have problems such as complex structures, difficult debugging, and high costs.

It is a stable supporting device, the discharging is controllable, and the feed accumulation and blockage are avoided.

[0032] A method for using a mouse feed proportioning device includes the following steps: S1. Check whether the feeding proportioning device is deformed, rusted or stuck; verify whether the discharging valve 32 of the discharging assembly 3 opens and closes flexibly, and whether the inner wall of the discharging hopper 31 is smooth without residues; check whether the welding points of the supporting legs 41 and the stabilizing plate 42 are firm to avoid shaking during equipment operation, use a torque wrench to confirm the bolt connection torque of the installation groove 212 and the feeding pipe 221, and check whether the cleaning inner lining 243 of the dust-proof cap 24 fits the inner wall of the centralized feeding cylinder 21 completely without gaps; start the telescopic cylinder 231 without load, observe whether the inclination angle of the tipping plate 235 reaches the preset value and whether the action is smooth, avoid proportioning errors or equipment failures caused by component loosening or wear, and ensure the stability of batch production; reduce the operation risk through pre-inspection and extend the service life of the equipment; S2. According to the formula requirements, pour different nutritional components into the corresponding feeding hoppers 223 respectively, and tighten the cover plate 224 to prevent dust; the bottom of the blanking cylinder 222 is integrated with a weighing sensor to monitor the weight of the feed on the tipping plate 235 in real time, and the data is synchronized to the control terminal; if a certain component is overweight or insufficient, the system will automatically alarm and pause the process, prompting manual intervention; realize independent storage and precise metering of multiple components, avoiding cross-contamination; the weighing sensor and the automatic alarm system ensure the proportioning consistency and meet the nutritional standards of experimental animals; S3. The control terminal sends an instruction, the telescopic cylinder 231 drives the telescopic rod 232 to contract, the discharging plate 235 tilts around the fixed shaft 236, and the feed slides along the inclined plane into the feeding pipe 221; the inclined plane angle at the bottom of the feeding pipe 221 and the surface polishing treatment ensure that the feed slides into the centralized feeding cylinder 21 without residue; each component of the feed vertically falls into the silo cylinder body 1 through the centralized feeding cylinder 21, and the stirrer in the cylinder body starts pre-mixing synchronously; the tilting action of the discharging plate 235 cooperates with the inclined plane of the feeding pipe 221 to achieve rapid emptying and improved efficiency; the vertical feeding of the centralized feeding cylinder 21 reduces feed dusting, and with the sealing performance of the dust-proof cap 24, the amount of dust overflow is reduced; S4. Set the rotation speed and mixing time of the stirrer to ensure the uniformity of the feed; after mixing is completed, open the discharge valve 32 to a half-open state to control the feed flow rate; the inner wall of the discharge hopper 31 is made of food-grade stainless steel, and the bottom cone angle ≥ 60° to prevent feed from sticking to the wall; high-speed stirring shortens the mixing cycle, and the uniformity reaches over 98%, meeting the specifications of experimental animal feed; the discharge valve 32 accurately controls the flow rate to adapt to the needs of different packaging containers; S5. When the feeding hopper 223 is lifted upward, the bottom scraping plate 228 slides closely along the inner wall of the blanking cylinder 222, scraping the residual feed to the area of the discharging plate 235; press the positioning column 226 to unlock the feeding hopper 223, and after separation, it is rinsed separately to avoid cleaning dead corners; the design of the scraping plate 228 fitting with the inner wall reduces the residue amount and saves cleaning time; the modular structure supports rapid disassembly and assembly to adapt to the needs of high-frequency production; S6. When the dust-proof cap 24 is lifted upward, the cleaning lining 243 moves upward synchronously with the opening 244, and its edge scrapes the residual feed at the installation groove 212; after removing the cleaning lining 243, it is rinsed with a food-grade cleaning agent, and the caking on the inner wall of the centralized feeding cylinder 21 is removed by a high-pressure water gun; the linkage mechanism between the cleaning lining 243 and the opening 244 avoids manual scraping from damaging the equipment; the detachable design supports high-temperature sterilization to meet the requirements of the sterile environment in the laboratory.

S2, opening the cover plate (224), pouring the ingredients of the mouse feed from different hoppers (223), into the drop barrel (222), and dropping them onto the pouring plate (235), and using a detection instrument to detect the feed proportion; S3, starting the telescopic cylinder (231) to drive the telescopic rod (232) to extend and retract, tilting a sufficient amount of mouse feed ingredients on the pouring plate (235) into the feed pipe (221), sliding along the inclined surface of the bottom of the feed pipe (221) into the centralized feed barrel (21), and being collected in the silo barrel (1); S4, the different ingredients are stirred and mixed in the silo cylinder (1), and finally the feed is discharged from the discharge hopper (31) through the discharge valve (32); S5, after the feed mixing is completed, the feed hopper (223) is lifted upward, and the scraper plate (228) at the bottom thereof simultaneously cleans the feed remaining inside the discharge barrel (222); S6. After each feed hopper (223) is disassembled, the dust cap (24) is lifted upward, and the cleaning liner (243) at the bottom thereof is moved upward, and the inner wall of the centralized feed barrel (21) is cleaned at the same time. When the opening (244) moves upward, the feed remaining in the mounting groove (212) is scraped off, and then the disassembled feed hopper (223) and the cleaning liner (243) are cleaned to complete the overall cleaning.
