Description

Technical Field

[0001] The present application relates to the field of experimental animal feeding, and in particular to a multifunctional and convenient experimental animal feeding vehicle. Background Art

[0002] Toxicological safety evaluation uses experimental animals as test tools to simulate the toxic effects under conditions of human exposure, and to extrapolate the experimental results of animals to humans. Therefore, animal husbandry is an indispensable part of the experimental process. The model animals used in the laboratory are mainly guinea pigs, mice and rats, and rabbits. Unlike collective breeding in farms, most laboratory animals need to be raised in single cages, and each cage corresponds to a feed box. Therefore, feeding is an indispensable part of daily work. At present, the traditional feeding method is used. First, the animal feed is transferred from a large package to a small feed box, and then the feed is transported to the laboratory by a cart, and then fed into a single cage with a feed shovel. The defects of this process are: the feed packaging process is very time-consuming and labor-intensive, and requires the participation of a large number of staff.

[0003] To this end, Chinese utility model patent application number 2023235520928 discloses a feed feeding device for livestock farming. This device enables automatic feeding and adjustable feed distribution. However, the aforementioned feed feeding device has certain drawbacks during use. For example, when the feed feeding device stores a large amount of feed, the accumulation of feed pellets inside the device can easily cause jamming during discharge. Utility Model Content

[0007] Among them, the feeding device is provided with a stirring rod for stirring the feed, which can avoid the problem of discharge jamming caused by internal feed accumulation or compaction.

[0008] Preferably, the feeding device also includes a fixed plate, a spring and a stirring blade. The fixed plate is fixed to the bottom end of the feeding box. The fixed plate is provided with a through hole for the stirring rod to pass through. The stirring blade is fixed on the stirring rod. One end of the spring is fixed to the stirring blade, and the other end is fixed to the fixed plate.

[0009] The spring drives the stirring blade to return to its original position, and the cam is used to drive the stirring blade to ensure that the feed particles are stirred periodically.

DETAILED DESCRIPTION

[0025] The following will describe the implementation methods of this application in detail with reference to the accompanying drawings and examples, so that the application can fully understand how technical means are used to solve technical problems and achieve corresponding technical effects, and implement them accordingly. The embodiments of this application and the various features therein can be combined with each other without conflict, and the resulting technical solutions are all within the scope of protection of this application.

[0026] It should be clear that the embodiments described below are only some of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of this application. Example 1

[0027] like Figure 1-Figure 5 As shown, a multifunctional and convenient experimental animal feeding vehicle includes a feeding device to prevent feeding jams, and the feeding device includes a rotary drive motor 4, a feeding box 5, a cam 10 and a stirring rod 11.

[0028] The output end 9 of the rotary drive motor 4 is synchronously connected to the cam 10 , the end of the stirring rod 11 is connected to the side end of the cam 10 , and the cam 10 and the stirring rod 11 are both arranged in the feeding box 5 .

[0029] In addition, the feeding device also includes a fixed plate 14, a spring 12 and a stirring blade 13. The fixed plate 14 is fixed to the bottom end of the feeding box 5. The fixed plate 14 is provided with a through hole for the stirring rod 11 to pass through. The stirring blade 13 is fixed on the stirring rod 11. One end of the spring 12 is fixed to the stirring blade 13, and the other end is fixed to the fixed plate 14.

[0030] Internal components and working principle of the feeding device:

[0031] like Figure 3-Figure 5 As shown, when the feed discharge is stuck, the rotation drive motor 4 is started to drive the cam 10 to rotate. Since the cam 10 periodically drives the stirring rod 11 to extend and slide in the through hole of the fixed plate 14 during the rotation process, the feed particles can be stirred to prevent the feed particles from piling up and causing discharge jams.

[0032] Moreover, when the cam 10 drives the stirring rod 11 to move periodically, the spring 12 is squeezed. Therefore, the end of the stirring rod 11 is always in contact with the side end of the cam 10.

[0033] like Figure 6 As shown, the feed box 5 is connected to the discharge hopper 6 below. The channel inside the discharge hopper 6 is almost vertical, so the probability of jamming is very low. Therefore, the feeding device is arranged inside the feed box 5. As long as the feed particles inside the feed box 5 are not compacted together, the feed can be discharged smoothly.

[0034] In this embodiment, a storage trough 2 is provided on the upper end of the feeding cart body 7. When the temporary feed box feed cannot meet the animal supply, the stored feed is put into the temporary storage box to continue feeding, reducing repeated visits to the feed storage room to take feed, saving time and cost, and speeding up work efficiency.

[0035] In this embodiment, the feeding device is installed at the upper end of the feeding vehicle body 7, and an opening and closing partition plate 3 is slidably installed between the storage trough 2 and the feeding box 5.

[0036] In the present embodiment, the lower end of the feeding cart body 7 is provided with a rolling wheel 8. By arranging the rolling wheel 8, free and flexible movement can be achieved without noise.

[0037] In this embodiment, a force-applying push rod 1 is provided at the side end of the feeding cart body 7 .

[0038] In actual applications, some experimental projects require recording the daily food intake or total calorie intake of animals. According to traditional feeding methods, each feed addition must be weighed on a scale and then transferred to the feed box. The operation process is cumbersome. If the feed is dropped during the process, it must be re-weighed, which greatly reduces experimental efficiency. Therefore, when the experimental animal feeding cart is actually used, it can be equipped with a weight sensor as needed to accurately weigh the weight of the feed in the feed box and record the data in real time. Example 2

[0039] In practice, because mouse cages are typically arranged in five rows and five to six columns, which have a certain height, the experimental animal feeding cart provided in this embodiment incorporates a lifting rail 16 and a drive cylinder 15. The lifting rail 16 is provided with a sliding groove, and correspondingly, a slider is provided at the side of the feed trough 2, which slides within the groove. The output end of the drive cylinder 15 is fixed to the slider. In other words, when the feed trough 2 needs to be raised, the drive cylinder 15 can be used to drive the slider to the appropriate height, thereby adjusting the height.

[0040] Moreover, since the storage trough 2 may contain a lot of feed, the single force application handle is not conducive to the thrust application during the pushing process, so the single force application handle can be used to apply the force. Figure 6As shown, adding a force-bearing handle can make the storage trough 2 more convenient to push.

[0041] At the same time, in order to prevent the feeding cart from moving accidentally, a braking device is installed on the rollers of the feeding cart. The braking device can refer to the pressure brake of the rollers on the baby carriage, which is suitable for the staff to decide whether to fix the rollers of the feeding cart according to the actual cleaning.
