Description

Technical Field

[0001] The utility model relates to the field of experimental animal auxiliary equipment, and particularly relates to a bedding transfer and separation device for an experimental animal house. Background Art

[0002] When raising mice, rats, rabbits, etc. in the animal house, bedding such as wood shavings or corncobs must be used. Due to their strong water absorption, they are the most commonly used bedding. The reason for using bedding is that rodents prefer a flat cage bottom with bedding. The bedding can absorb urine and feces, facilitating cleaning. For animals such as mice, rats, and rabbits, direct contact with the bedding increases their opportunities to express their natural instincts, such as searching, digging, and nesting. In addition, another important purpose of using bedding is that it absorbs the moisture in urine and feces, keeping the microenvironment dry. Used bedding contains animal feces and urine. Microorganisms decompose urea in the urine, producing ammonia and carbon dioxide. The bedding absorbs moisture, inhibiting the reproduction of microorganisms, and thus preventing the accumulation of ammonia and harmful bacterial toxins in the microenvironment. However, if the ammonia level in the microenvironment rises, or the bedding absorption reaches saturation, continued use will cause respiratory damage and eye problems. Some studies have shown that when the ammonia concentration reaches 4 mL / L (about 0.003 mg / m3), it will cause eye irritation. When staff are exposed to a high ammonia concentration environment for a long time, they will experience symptoms such as coughing and allergies.

[0003] In the prior art, usually, plastic bags or other bags are used to collect the bedding in the animal house, and then the bedding is transported outside the experimental house area by a transport vehicle for environmental protection and safe treatment. The utility model person designed a transfer device that can separate feces from the bedding for this problem. The utility model date is October 18, 2023, and the authorization date is May 28, 2024. Its utility model number is 2023227909760, and the patent name is: Experimental animal bedding transfer device.

[0004] However, when the utility model person used this solution, it was found that the device had problems of incomplete separation of pollutant particles from the bedding and low separation efficiency. In particular, pollutants such as feces and feed residues wrapped in the middle of the bedding were difficult to quickly and thoroughly separate from the upper or middle part of the box to the bottom.

[0005] Therefore, the prior art urgently needs to be improved. Summary of the Utility Model

[0006] In view of the shortcomings of the prior art, the purpose of the present utility model is to provide a bedding transfer and separation device for an experimental animal house to solve the problems of incomplete separation of pollutants from the bedding and low separation efficiency in the existing bedding transfer device, especially the problem that it is difficult to quickly separate pollutants such as feces and feed residues wrapped in the middle of the bedding.

[0007] To achieve the above object, the utility model adopts the following technical solutions: A litter transfer and separation device for an experimental animal room, which includes a feeding unit, an operating unit, and a driving unit arranged from top to bottom. The feeding unit receives pollutants mixed with litter and selectively communicates with the operating unit to transfer the pollutants to the operating unit. The driving unit is used to drive the litter transfer and separation device of the experimental animal room to move to a designated position. The operating unit includes a box body with a hollow cavity, a filtering part, and a turning part.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model. In the present utility model, unless otherwise stated, the orientation words such as "upper", "lower", "left", "right", "front", and "rear" generally refer to the upper, lower, left, and right in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings.

[0026] It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present utility model. And in the following embodiments, each embodiment has its own emphasis. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0027] As mentioned above, bedding must be used during the temporary storage of animals in the animal house. After being used by animals, the bedding is mixed with pollutants, forming a mixture of bedding and pollutants. The pollutants generally include small particulate matters such as animal feces and residual feed. The odor in the used bedding mainly comes from the pollutants. The bedding is generally made of wood shavings or corncobs with good water absorption, and the particle size is generally larger than the feces of experimental animals (such as rats, mice, etc.). The volume of the bedding that absorbs urine will also shrink. Therefore, pollutants such as feed residues, feces, or bedding contaminated with animal feces are also the root causes of odor generation.

[0028] The solution of the present utility model aims to solve the problems of low separation efficiency and incomplete separation between the bedding and feces. By flipping and separating the mixture of bedding and pollutants in the bedding used by animals, the problems of odor escape during collection and transportation and cumbersome loading and unloading operations are further solved.

[0029] Please refer to Figure 1, A bedding transfer and separation device for experimental animal houses is shown in the figure, which includes an operation unit 100, a feeding unit 200, and a driving unit 300. The operation unit 100 is fixedly connected to the feeding unit 200 and the driving unit 300 respectively. The operation unit 100 includes a box body 110 with a hollow chamber. The driving unit 300 is used to drive the movement of the box body 110. The feeding unit 200 is selectively connected to the chamber of the box body 110. That is, when feeding is required, the feeding unit 200 is connected to the chamber of the box body 110, and the bedding and pollutants enter the chamber of the box body 110 through the feeding unit 200. When feeding is not required, the feeding unit 200 is sealed from the chamber of the box body 110, thereby preventing the odor in the bedding from being emitted into the air through the feeding unit 200. Details will be described later.

[0030] Preferably, the feeding unit 200 and the driving unit 300 are arranged on opposite sides of the box body 110, that is, the feeding unit 200 and the driving unit 300 are separately arranged. In Figure 1 In this specific embodiment, the feeding unit 200 is arranged on the upper side of the box body 110, and the driving unit 300 is arranged on the lower side of the box body 110. The advantage of this arrangement is that it can better separate the bedding by taking advantage of the different gravities of various wastes in the bedding.

[0031] It can be understood that the driving unit 300 is used to drive the movement of the box body 110, and there are many solutions in the prior art. In Figure 1 In this specific embodiment, the driving unit 300 includes a plurality of universal wheels, and the plurality of universal wheels are independently arranged. Of course, they can also be arranged in an associated manner to better control the movement direction of the box body 110. In another alternative embodiment, the driving unit 300 is a detachable fixing part that is fixedly matched with other transmission devices (such as a conveyor belt). For example, the driving unit 300 can be a magnet that is magnetically connected to other transmission devices. The advantage of this arrangement is that it is especially suitable for simultaneously transporting multiple box bodies 110 to improve the transfer efficiency.

[0032] Specifically, the operation unit 100 further includes a filtering part 120, a collecting part 130, and a separating part. The filtering part 120, the collecting part 130, and the separating part are all accommodated in the chamber of the box body 110. The filtering part 120 divides the chamber of the cavity into a first chamber 111 on the side close to the feeding unit 200 and a second chamber 112 close to the driving unit 300. In Figure 1 In this specific embodiment, the feeding unit 200 is arranged on the upper side, and the driving unit 300 is arranged on the lower side. Correspondingly, the first chamber 111 is arranged on the upper side, and the second chamber 112 is arranged on the lower side.

[0033] Please continue to refer to Figure 1, the feeding unit 200 is selectively communicated with the chamber of the box body 110. The feeding unit 200 is used to receive the mixture of bedding and pollutants by the operator. There are various ways for the selective communication between the feeding unit 200 and the box body 110. In a specific embodiment, the feeding unit 200 is periodically switched on and off with the box body 110, that is, the feeding unit 200 is switched on and off within a set time period. In another specific embodiment, a gravity sensor is provided on the feeding unit 200, and the communication with the box body 110 is opened after the mixture is sensed to reach the set weight.

[0034] Preferably, the feeding unit 200 is preferably a funnel-shaped structure with a continuously narrowing size on the side close to the box body 110. The advantage of such a setting is that it can better gather the mixture of bedding and pollutants, and then, when the feeding unit 200 is communicated with the box body 110, it can better complete the delivery of the mixture of bedding and pollutants in the feeding box to the chamber of the box body 110.

[0035] Please continue to refer to Figure 1 , the filtering part 120 is used to make the pollutants in the first chamber 111 enter the second chamber 112, so as to realize the separation of pollutants and bedding. For the specific structural design of the filtering part 120, the filtering part 120 is preferably a filter net, which can well realize the separation of pollutants and bedding. The mesh number of the filter net can be selected according to needs, and no specific limitation is made.

[0036] In a specific embodiment, the filtering part 120 can make the pollutants in the first chamber 111 enter the second chamber 112 unidirectionally. At this time, the filtering part 120 is a plate-like structure with a plurality of filter holes, and the filter holes are set in an "S" shape or other curved structures, so as to prevent the pollutants from returning from the second chamber 112 to the first chamber 111.

[0037] Furthermore, the filtering part 120 can also selectively seal the second chamber 112, that is, the filtering part 120 can be selectively switched on and off to further prevent the diffusion of the odor of pollutants. In a specific embodiment, the filtering part 120 further includes a switch board, which is arranged on one side of the filter net and is used to selectively isolate the first chamber 111 and the second chamber 112, so as to reduce the diffusion of foreign matters of the pollutants in the second chamber 112 to the first chamber 111. When it is necessary to communicate the first chamber 111 and the second chamber 112 and make the pollutants enter the second chamber 112 from the first chamber 111, the switch board is opened. Correspondingly, when it is not necessary to make the pollutants enter the second chamber 112 from the first chamber 111, the switch board is closed to realize the sealing of the second chamber 112. Further, the switch board is preferably a folding switch board, and the switch board is opened or closed by means of multiple folds. Of course, it can also be opened or closed by electric or mechanical components, which will not be elaborated here.

[0038] Similarly, for the feeding unit 200, a switch board can also be provided to selectively isolate the first chamber 111 and the feeding unit 200, thereby reducing the diffusion of foreign substances of pollutants in the first chamber 111 into the feeding unit 200. When it is necessary to connect the first chamber 111 and the feeding unit 200 so that pollutants enter the second chamber 112 from the feeding unit 200, the switch board is opened. Correspondingly, when it is not necessary to allow pollutants to enter the second chamber 112 from the first chamber 111, the switch board is closed to achieve the sealing of the second chamber 112. Further, the switch board is preferably a folding switch board, and the switch board is opened or closed by means of multiple folding. Of course, it can also be opened or closed by electric or mechanical components, which will not be elaborated here.

[0039] Please continue to refer to Figure 1 , the collection part 130 is arranged in the second chamber 112 and is detachably sealed with the box body 110. The collection part 130 is preferably an open box body, and the collection part 130 matches the second chamber 112 so that the collection part 130 can just collect the pollutants entering the second chamber 112 from the filtering part 120. The collection part 130 can be freely moved into or out of the second chamber 112 and is detachably connected to the box body 110, thereby facilitating the operator to freely take the collection part 130 and then process the pollutants collected in the collection part 130. Further, the collection part 130 is also hermetically connected to the box body 110 to further prevent the odor of the pollutants collected in the collection part 130 from spreading. In a specific manner, the collection part 130 and the box body 110 are moved into and out of each other through a slide rail. Preferably, a handle is provided on the collection part 130 for the convenience of the operator to move it in and out.

[0040] Please continue to refer to Figure 1 , the turning part 140 is arranged in the first chamber 111. The turning part 140 is used to turn the mixture of bedding and pollutants in the first chamber 111 so that the pollutants and bedding are separated under the action of gravity, and the pollutants enter the second chamber 112 through the filtering part 120. The turning part 140 includes a roller 141 and a rotating part 142. The roller 141 includes multiple partitions and a central axis similar to a cylinder. The partitions are arranged in the radial direction of the central axis and are fixedly connected to the central axis at one end. The partitions are preferably 6-8 pieces. One ends of the multiple partitions are fixed to each other to form a "*" shaped structure. The rotating part 142 is in transmission connection with the partitions and is used to drive the partitions to rotate.

[0041] Preferably, each partition of drum 141 is provided with multiple small holes. This arrangement facilitates the flow of pollutants, such as solid feces and feed residue, through the small holes and downwardly collects them onto the filter screen. The multiple partitions are fixedly connected to the central shaft at one end near the center of the rotating shaft, while the other end selectively contacts the bedding and mixture. Similarly, the central shaft has multiple through-holes, facilitating the rapid entry of particulate pollutants into the lower chamber.

[0042] In one specific embodiment, the rotating member 142 is a rotating handle that is rotatably mounted on the outside of the housing and fixedly connected to the central axis of the drum 141. Rotating the rotating handle drives the central axis to rotate relative to the housing, thereby rotating the partition. In another specific embodiment, the rotating member 142 is a motor, the output end of which is fixedly connected to the partition, and the motor is used to rotate the partition.

[0043] Thus, by configuring the housing 110 to comprise a first chamber 111 and a second chamber 112 for accommodating pollutants, and arranging the second chamber 112 on the side of the first chamber 111 away from the collection portion 130, it is possible to minimize the spread of odors caused by pollutants through the feeding unit 200, thereby minimizing the spread of odors during transport. Furthermore, since the bedding and pollutants are separated, the first chamber 111 primarily contains the bedding. The presence of the bedding makes it more difficult for the odors of pollutants in the second chamber 112 to diffuse from the feeding unit 200 through the first chamber 111, thereby reducing the spread of odors during transport.

[0044] At the same time, by providing the flipping portion 140 and rotating the drum 141 under the drive of the rotating member 142, the flipping of the bedding and the pollutants in the first chamber 111 can be well achieved. By rotating the drum 141 to achieve the rotation and flipping of the bedding, the upper layer of bedding and pollutants near the feeding unit 200 in the first chamber 111 are replaced to the lower layer by rotation and flipping, and during the flipping and replacement process of the upper layer of bedding and pollutants, the pollutants are separated from the bedding due to the action of gravity, and the pollutants enter the second chamber 112 through the filter portion 120. And through continuous rotation and collection, the pollutants in the bedding can be continuously separated and sent to the second chamber 112. Ultimately, the bedding is accommodated in the first chamber 111 and the pollutants are accommodated in the second chamber 112.

[0045] It should be noted that the gap between the end of the partition on the drum 141 and the filter part 120 is preferably as close to the filter part 120 as possible. The advantage of this setting is that it can drive more padding and pollutants to flip through the partition as much as possible, thereby improving the separation efficiency.

[0046] In a specific embodiment, the operating unit 100 further includes a blower (not shown in the figure), which is arranged on the side wall of the first chamber 111 and is arranged toward the filter unit 120. Figure 1 In this specific embodiment, the blower is installed on the left and right side walls of the first chamber 111 of the housing 110 and is positioned below the opening. The advantage of this arrangement is that, by providing the blower and cooperating with the turning portion 140, the mixture of bedding material and pollutants in the first chamber can be rotated and turned as much as possible, and the relative positions can be adjusted, thereby allowing as much pollutant as possible to pass through the filter portion 120 and enter the second chamber 112.

[0047] In another specific embodiment, the operating unit 100 further includes a controller, which is electrically connected to the flip part 140 and the blower. The controller is used to control the blower and the flip part 140 to operate without interfering with each other, that is, when the blower is working, the flip part 140 is not working, and when the blower stops working, the flip part 140 starts working; when the flip part 140 is working, the blower is not working, and when the flip part 140 stops working, the blower starts working. The advantage of such a setting is that by making the blower and the flip part 140 work intermittently, it is possible to avoid conflicts that may be caused by the blower and the flip part 140 working at the same time, for example, making some pollutants unable to reach the filter part 120 and then enter the second chamber 112, thereby effectively improving the separation efficiency of the padding and pollutants.

[0048] Furthermore, the controller is also electrically connected to the feeding unit 200 and the filter section 120, and is used to selectively control the switch of the feeding unit 200 or the filter section 120 respectively. The advantage of this arrangement is that the first chamber 111 and the second chamber 112 can be further formed into closed chambers, thereby minimizing odor diffusion and protecting operators.

[0049] Please continue reading Figure 1 The box body 110 further includes a movable door 150, which is disposed on the side wall of the box body 110 corresponding to the first chamber 111 of the cavity. The movable door 150 is used to selectively open the first chamber 111 to remove the padding and contaminants in the first chamber 111. Figure 1 In this specific embodiment, the movable door 150 is roughly pivoted at the connection between the first chamber 111 and the filter part 120. The advantage of this arrangement is that when the operator takes the bedding and contaminants in the first chamber 111, it is used to avoid the bedding and contaminants from leaking out of the box body 110 as much as possible, thereby requiring the operator to clean it again.

[0050] Of course, in an alternative embodiment, the movable door 150 may not be provided, and the bedding may be taken out by pulling the roller 141 in the horizontal direction (axial direction). In this case, it is required that connecting plates for circumferentially connecting the plurality of partition plates are provided at the axial ends of the plurality of partition plates of the roller 141, so that when the roller 141 moves axially, the bedding and pollutants between the partition plates can be taken out together. Therefore, it can be understood that the present utility model only requires that the bedding or pollutants in the first chamber 111 can be taken out, and the specific method is not limited.

[0051] In summary, an experimental animal house bedding transfer and separation device provided by the present application mainly includes a box body, a feeding port (feeding unit), a roller, a filter screen (filtering part), a rotating handle, a feces collection box (collection part), etc. The roller is set as a cylinder composed of 6-8 partition plates, so that both sides of the roller are movably connected to the box body, and it can be rotated along the central axis by a rotating handle located outside the box body. The filter screen (filtering part) is located below the roller, and the gap between the lower edge of the roller and the filter screen is appropriate. The filter screen is located below the roller and is made of stainless steel or plastic material, and the size of its mesh holes is determined according to the particle size of different bedding. The feces collection box (collection part) is located below the filter screen (filtering part) and can be pulled out of the box body through a handle. By rotating the roller, the bedding can be driven to rotate, and the upper-layer bedding and its pollutants are carried to the lower layer. Particles such as feces and feed residues are separated to the bottom collection box through the filter screen, avoiding the problem that pollutants in the upper-layer bedding are not easily separated from the entire bedding layer.

[0052] An experimental animal house bedding transfer and separation device provided by the present utility model is used to separate severely contaminated bedding from the discarded bedding. At the same time, the clean bedding can also play a sealing role to seal the severely contaminated bedding waste, facilitating the diffusion of odor during the collection, transfer, and loading and unloading of the bedding and other waste, and avoiding direct contact between personnel and waste such as large animal feces, small animal bedding, and biological waste during the loading and unloading process. Through a simple design, the working environment is improved and the usability is enhanced.

[0053] On the one hand, after a part of the bedding is filled, the roller can be rotated by the rotating handle, so as to drive the bedding, feces, feed residues and other contaminants into the lower layer. Among them, contaminants such as feces and feed residues enter the collection box through the gaps of the filter screen, while the bedding continues to stay in the upper box body, and finally the contaminants such as feces and feed residues in the bedding can be quickly and thoroughly separated from the bedding.

[0054] On the other hand, by continuously rotating the drum, small particulate pollutants such as feces and feed residues can be separated from the bedding in multiple cycles, and the separation is thorough and sufficient. The collection box is sealed at the bottom of the transfer vehicle, while the uncontaminated large particulate bedding is located in the upper layer of the device's box body. The coordination between the bedding and the drum seals the pollutants, further preventing the odor from spreading in the air and reducing the exposure amount of the odor. At the same time, the collected pollutants can be taken out from the collection part for treatment; the separated bedding can be taken out from the side door for treatment; or the bedding can be taken out by pulling out the drum horizontally.
