Description

Technical Field

[0001] The utility model relates to the technical field of animal breeding, in particular to a feeding device for experimental animals. Background Art

[0002] In experiments using animals as experimental subjects, in research fields such as biology, animal psychology, animal behavior, and drug effects, there are steps to feed experimental animals drugs. Especially in some experiments that require long-term tracking and recording of data, it is necessary to control various variables such as the type, ratio, dosage, and feeding interval of the drugs fed each time according to the experimental requirements.

[0003] The existing device mixes multiple feeds and medicines together through a stirring component, and then allows the feed to slide into the feeding area to feed the small animals. However, when there are many small animals under the same breeding conditions, it is necessary to prepare feed for the small animals multiple times. On the one hand, multiple preparations will affect the feeding efficiency. On the other hand, due to the situation of feed or medicine sticking to the wall each time, there will be slight differences in the prepared medicines, which will affect the accuracy of the experimental results.

[0017] An experimental animal feeding device includes a mounting frame 1, a cylinder 2 mounted on the mounting frame 1, a feed port 3, a stirring assembly 4 and a food distribution assembly 5 arranged in sequence in the cylinder 2 from top to bottom, and a plurality of feeding assemblies 6 arranged around the bottom of the cylinder 2 and the upper part of which passes through the bottom plate of the cylinder 2 and is connected to the food distribution assembly 5; the food distribution assembly 5 includes a first mounting plate 51 and a second mounting plate 52 fixed in parallel in the cylinder 2, a rotating shaft 53 fixed between the first mounting plate 51 and the second mounting plate 52 and the upper part of which passes through the first mounting plate 51 and extends to the top of the first mounting plate 51, and a fixed bottom of the second mounting plate 52 with an output shaft passing through the second mounting plate 52 and fixed to the shaft end of the rotating shaft 53. A first motor 54, a turntable 55 rotatably arranged between the first mounting plate 51 and the second mounting plate 52 and fixed to the rotating shaft 53, and a plurality of push plates 56 fixedly arranged around the upper part of the rotating shaft 53 and with the bottom abutting against the upper surface of the first mounting plate 51; the first mounting plate 51 is surrounded by a plurality of first through-channels 511, the turntable 55 is surrounded by a plurality of second through-channels 551 staggered with the push plates 56, and the second mounting plate 52 is surrounded by a plurality of third through-channels 521; the first through-channels 511, the second through-channels 551, and the third through-channels 521 are matched one by one with the push plates 56 and the bottom of the third through-channel 521 is connected to the corresponding feeding component 6.

[0018] By pouring a variety of feeds and medicines from the feed port 3 in sequence, and then stirring them in the stirring component 4, after the stirring is completed, the feeding component 5 divides the feed containing the medicine into several portions as evenly as possible and then transports them to the corresponding feeding components 6 to feed the animals. In this process, small animals with the same breeding conditions can be fed in batches. On the one hand, it can improve the feeding efficiency of experimental animals, and on the other hand, it can minimize the occurrence of slight differences in the weight, internal ratio, etc. of feed and medicine, thereby improving the accuracy of experimental animal experimental data.

[0019] As a possible implementation of this scheme, preferably, the stirring assembly 4 includes a support seat 41 fixed in the cylinder 2, a stirring barrel 42 fixed to the upper surface of the support seat 41, a stirring roller 43 circumferentially rotatable and fixed in the stirring barrel 42, and a second motor 44 fixed to the bottom of the stirring barrel 42 and with an output shaft passing through the bottom plate of the stirring barrel 42 and fixed to the shaft end of the stirring roller 43; the top of the stirring barrel 42 is provided with a feed pipe 421 connected to the feed port 3 and the bottom is provided with a discharge pipe 422 located above the first mounting plate 51, and the discharge pipe 422 is provided with an electric valve 423; the second motor 44 drives the stirring roller 43 to rotate, thereby mixing the various feeds and medicines in the stirring barrel 42 to realize the configuration of the drug-containing feed required for the experimental animals.

[0020] As a possible implementation of the present scheme, preferably, each group of the feeding components 6 includes a feeding box 61 located below the bracket and a feed pipe 62 for connecting the feeding box 61 with the corresponding third through channel 521; a drawer 611 is slidingly provided at the lower part of the feeding box 61, and the drawer 611 is provided with a handle 612; the divided feed can be transported to the feeding box 61 through the feed pipe 62, so as to feed the small animals.

[0021] As a possible implementation of the present scheme, preferably, an electric push rod 7 is fixed to the lower surface of the mounting frame 1, and the driving end of the electric push rod 7 is hinged with a plurality of connecting rods 8 that are adapted one by one to the drawers 611; the connecting rods 8 are hinged to the drawers 611; the driving end of the electric push rod 7 pushes the connecting rods 8 to move downward, thereby driving the drawer 611 to move toward the outside of the feeding box 61, so that the feed containing medicine in the drawer 611 can be eaten by the animals. When feeding is not needed, the driving end of the electric push rod 7 drives the connecting rods 8 to move upward, thereby driving the drawer 611 to move into the feeding box 61, so that the feeding box 61 is closed and the animals cannot eat.

[0022] The working principle of this device is:

[0023] In the first step, a variety of feeds and medicines are poured into the barrel 2 from the feed port 3 in sequence, so that the feeds and medicines enter the mixing barrel 42 along the feed pipe 421. At this time, the electric valve 423 is in a closed state. After all the feeds and medicines are placed in the mixing barrel 42, the second motor 44 is turned on to make the stirring roller 43 stir and mix the feeds and medicines in the mixing barrel 42.

[0024] In the second step, after the various feeds and medicines are evenly mixed, the electric valve 423 is opened to allow the mixed feed to fall to the top of the first mounting plate 51. At this time, the first motor 54 is driven to drive the rotating shaft 53 to rotate, so that the push plate 56 pushes the medicine-containing feed to the first through-channel 511. The feed falls into the first through-channel 511 due to gravity. At this time, since the second through-channel 551 of the turntable 55 is not connected to the first through-channel 511, the medicine-containing feed will remain in the first through-channel 511. The rotating shaft 53 continues to rotate. At this time, the medicine-containing feed higher than the first through-channel 511 will leave the first through-channel 511 as pushed by the push plate 56. At the same time, the turntable 55 rotates until the second through-channel 551 is connected to the first through-channel 511. At this time, the medicine-containing feed in the first through-channel 511 will fall into the drawer 611 in the feeding box 61 along the second through-channel 551, the third through-channel 521, and the feed pipe 62 under the action of gravity. The above operation is repeated until no feed remains on the top of the first mounting plate 51.

[0025] In the third step, the driving end of the electric push rod 7 drives the connecting rod 8 located on one side of the driving end of the electric push rod 7 to move downward. Since the length of the connecting rod 8 is fixed, the drawer 611 is pushed to move outward, allowing the animal to eat.

[0026] The above description is only a specific embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
