Description

A bedding exchange assembly, a feeding assembly, and a mouse feeding system Technical Field

[0001] This invention relates to the technical field of feeding equipment for laboratory mice, and in particular to a bedding replacement component, a feeding component, and a mouse feeding system. Background Technology

[0002] Laboratory animals are animals specifically bred for experimental purposes. They mainly refer to animals domesticated, bred, and raised for research, teaching, medical treatment, identification, diagnosis, and biological product manufacturing in medicine, pharmacy, biology, veterinary medicine, and other fields. For example, mice and rats are the first laboratory animals bred strictly according to experimental requirements. Other examples include hamsters, guinea pigs, other rodents, and quails, which have also been adopted as laboratory animals.

[0003] Laboratory mice refer to white-furred rats or mice commonly used as experimental animals in teaching and research in disciplines such as physiology, medicine, and pharmacy. Through long-term selection and targeted breeding, many breeds of laboratory mice have been developed. They are generally divided into two categories: commonly used laboratory mice and special laboratory mice designed to meet specific needs. Special laboratory mice include high-cancer mice, low-cancer mice, diabetic mice, and mice with congenital muscular atrophy, among others. Some classifications of laboratory mice are based on different hybridization methods and the acquired genetic characteristics, such as inbred strains, mutant strains, outcrossed strains, and hybrid groups. Mice have poorer self-regulation abilities to adapt to the environment and lower disease resistance than other laboratory animals. Furthermore, there are numerous breeds and strains of mice, each with its own specific requirements; therefore, a clean and comfortable living environment needs to be provided according to the actual situation.

[0004] Currently, mice are kept in cages during breeding. Typical cages are open-top plastic boxes. The inside of the box is lined with bedding materials such as sawdust and corncobs, then the mice are placed inside, and a wire mesh cover is placed on top. When changing the bedding, the mice must be transferred from the cage to another container, the waste bedding shoveled out and transported to a trash can, new bedding is added to the cage, and the mice are returned to the cage. During this process, the open top is placed on the ground, taking up operational space and easily becoming contaminated; when transporting waste bedding to the trash can, some waste easily falls to the ground, polluting the environment; when changing bedding in cages used for a large number of mice, the temporary containers for placing the mice lack a fixed storage location, posing a risk of escape, increasing management difficulty, and requiring significant manpower, making it time-consuming and labor-intensive.

[0005] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as the open top cover occupying operating space when placed on the ground, easy contamination, easy for waste to fall to the ground, risk of mouse escape, and high manpower requirements. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a bedding replacement assembly, a feeding assembly, and a mouse feeding system, thereby solving the problems of open top covers occupying operating space when placed on the ground, being easily contaminated, waste easily falling to the ground, the risk of mouse escape, and the need for a large amount of manpower.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The platform unit includes a feeder unit, located at the top of the platform unit and below the pull units and scraper units, for discharging the scraped old bedding; a feeder unit, located at the rear end of the platform unit, for storing new bedding for mice and reciprocating horizontally to enter the interior of the cage from the feeder outlet and transport the new bedding into the cage; and a control unit, located inside the corresponding feeder unit, for rotating vertically to control the discharge of new bedding from the feeder unit.

[0010] Secondly, the present invention provides a feeding assembly, placed at the top of a bedding replacement assembly as described in the first aspect, comprising: a feeding unit, wherein the feeding unit is disposed at the top of the platform unit of the bedding replacement assembly and is limited and connected to the limiting unit, for placing mice, limiting the position of the feeding unit under the action of the limiting unit, and allowing the corresponding scraping unit and the corresponding feeding unit to enter; a closing unit, wherein the closing unit is movably disposed at the rear end of the feeding unit and engages with the pulling unit of the bedding replacement assembly, for reciprocating vertically under the action of the pulling unit to open or close the discharge port of the feeding unit; a separating unit, wherein the separating unit is movably disposed inside the feeding unit and connected to the closing unit, for reciprocating vertically under the action of the closing unit to drive mice away from the bedding inside the feeding unit; and a cover unit, wherein the cover unit is detachably disposed at the top of the feeding unit for closing the feeding unit.

[0011] Thirdly, the present invention provides a mouse feeding system comprising: at least one bedding replacement assembly as described in the first aspect; at least one feeding assembly as described in the second aspect, the feeding assembly being removably disposed at the top of the bedding replacement assembly; and a storage assembly having the bedding replacement assembly and the feeding assembly disposed inside the storage assembly.

[0012] In some embodiments, the storage component includes: a storage unit, the storage unit having the bedding replacement component and the feeding component disposed inside; and a guide unit disposed on the side of the storage unit, connected to the storage unit, and communicating with the bedding replacement component.

[0013] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0014] This invention discloses a bedding replacement assembly, a feeding assembly, and a mouse feeding system. The platform unit and the limiting unit work together to confine the feeding cage within the bedding replacement assembly, improving the stability of the cage after placement and facilitating subsequent operations. The pulling unit, the closing unit, and the separating unit work together to lift the mice inside the feeding cage, separating them from the bedding. This replaces the use of external containers for temporary mouse placement, avoiding the risk of opening the cage lid and mouse escape, thus improving management convenience. The scraping unit and the discharge unit work together to scrape away the bedding inside the feeding cage, replacing the use of a shovel and improving operational convenience. The discharge unit directly discharges the scraped bedding, preventing waste from falling to the ground and polluting the environment when transporting bedding to the trash can. The feeding unit and the control unit work together to deliver new bedding to the feeding cage, reducing manual handling and increasing automation. Attached Figure Description

[0200] In some embodiments, the ninth drive element 173 is fixedly connected to the third rotating element 171 and the storage element 169, including but not limited to bolt connections.

[0201] In some of these embodiments, the ninth drive element 173 is a drive motor.

[0202] The method of using this invention is as follows:

[0203] (a) Placement of bedding and mice

[0204] Place the bedding and mice inside the cage in that order; place the lid on the opening at the top of the cage.

[0205] (ii) Placement of feeding cages

[0206] The feeding cage is placed inside the placement element 112 and engaged with the first limiting element 113 and the first pulling element 131; the first driving element 123 is activated, so that its output end drives the second limiting element 122 to move along the axis of the second sliding element 125 towards the feeding cage through the first movable element 121, until the second limiting element 122 is engaged with the feeding cage, thereby limiting the feeding cage between the first limiting element 113 and the second limiting element 122.

[0207] (iii) Open the feed outlet of the feeding cage.

[0208] The second drive element 132 is activated, causing its output end to open the feed outlet of the feeding cage through the first pull element 131.

[0209] (iv) Scrape off the bedding material in the feeding cage.

[0210] The fourth drive element 143 is activated, causing its output end to drive the second movable element 144 to move vertically downwards through the cooperation between the third drive element 142 and the third support element 141. This causes the scraping element 147 to gradually approach the feed outlet of the feeding cage. Finally, the fourth drive element 143 stops operating. The third drive element 142 is activated, causing its output end to drive the second movable element 144 to move horizontally towards the feeding cage. This causes the scraping element 147 to gradually enter the interior of the feeding cage. Finally, the third drive element 142 stops operating. The fifth drive element 1410 is activated, causing its output end to drive the first transmission element 1411 to rotate. The first transmission element 1411 rotates through the second transmission element 1412 and... The cooperation between the third transmission elements 1413 drives the second rotating element 149 to rotate around the circumference of the first rotating element 145. The second rotating element 149 drives the scraping element 147 to rotate accordingly until the scraping element 147 abuts against the third limiting element 146. The third driving element 142 is activated again, so that its output end drives the scraping element 147 to move horizontally away from the feeding cage through the second movable element 144. The scraping element 147 scrapes the bedding material inside the feeding cage to the sixth transmission element 154. The sixth driving element 155 is activated, so that its output end drives the sixth transmission element 154 through the fourth transmission element 152, thereby discharging the scraped bedding material through the sixth transmission element 154.

[0211] (v) Feeding the animals into the feeding cages

[0212] After the scraping unit 140 is reset, the seventh drive element 163 is activated, causing its output end to drive the sixth support element 164 along the length of the fifth support element 161 towards the rearing cage via the third movable element 162, until the sixth support element 164 enters the rearing cage, and then the seventh drive element 163 stops operating; the ninth drive element 173 is activated, causing its output end to drive the control element 172 to rotate via the third rotating element 171, thereby discharging the bedding material inside the storage element 169 from the discharge element 1610 onto the ninth transmission element 167; the eighth drive element 168 is activated. The seventh drive element 163 is activated, causing its output end to drive the ninth drive element 167 via the seventh drive element 165. The ninth drive element 167 then transports the bedding material inside the storage element 169 into the rearing cage. The seventh drive element 163 is activated again, causing its output end to drive the sixth support element 164 along the length of the fifth support element 161 away from the rearing cage via the third movable element 162, until the sixth support element 164 is gradually moved out of the rearing cage. During this process, as the sixth support element 164 gradually moves, the bedding material inside the storage element 169 can be evenly spread into the rearing cage.

[0213] (vi) Close the feed outlet of the feeding cage.

[0214] The second drive element 132 is activated, causing its output end to close the feed outlet of the feeding cage through the first pull element 131.

[0215] The advantages of this invention are as follows: the platform unit and the limiting unit work together to confine the rearing cage within the bedding replacement assembly, improving the stability of the rearing cage after placement and facilitating subsequent operations; the scraping unit and the discharge unit work together to scrape away the bedding inside the rearing cage, replacing the use of a shovel and improving operational convenience; and the discharge unit directly discharges the scraped bedding, preventing waste from falling to the ground and polluting the environment when the bedding is transported to the trash can; and the feeding unit and the control unit work together to deliver new bedding into the rearing cage, reducing manual handling and increasing the degree of automation.
