Description

Technical Field

[0001] This utility model relates to the field of bedding material cleaning technology, and in particular to a bedding material conveying device. Background Technology

[0002] In the field of biological research, small laboratory animals such as mice, rats, and guinea pigs are commonly used experimental subjects. To ensure the health of these animals and the accuracy of experiments, they are usually kept in specific cages, and bedding is an indispensable part of these cages. Bedding not only absorbs animal excrement and maintains environmental hygiene, but also reduces the concentration of harmful gases such as ammonia, maintains suitable temperature and humidity, keeps the cage dry, and provides comfortable nesting material for the animals, thus creating a suitable living environment.

[0003] In practice, adding bedding material is a process requiring precise operation. Workers need to accurately place the empty cages in front of the bedding conveyor, ensuring the cages are directly below the discharge port of the bedding adder. Then, the bedding adder is started, and the machine evenly adds bedding material to each cage. Once bedding addition is complete, the bedding conveyor transports these bedding-filled cages to the next location, while simultaneously moving new empty cages under the bedding adder for the next round of bedding addition.

[0004] However, some problems may occur during the bedding material addition process. Due to inaccurate alignment or other operational errors, bedding material may sometimes fall onto the bedding material conveying device. If not cleaned up in time, this scattered bedding material will gradually accumulate, not only affecting the smooth operation of the bedding material conveying device but also potentially causing equipment malfunction. Furthermore, in order to remove this accumulated bedding material, the staff has to stop the operation of the bedding material conveying device, which undoubtedly reduces the overall efficiency of bedding material addition. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a bedding material conveying device that does not require stopping the operation of the mesh chain conveyor during cleaning, thus ensuring the efficiency of bedding material addition.

[0006] To solve the above-mentioned technical problems, the present invention provides a bedding material conveying device, comprising a frame, a mesh chain conveying mechanism for conveying cages from front to back, a first guide groove for receiving bedding material, a second guide groove mounted on the frame, a swing drive mechanism mounted on the frame for driving the first guide groove to swing, and a recycling bin mounted below the discharge port on the front side of the second guide groove for collecting bedding material. The first guide groove is disposed between the upper and lower layers of the front part of the mesh chain conveying mechanism to receive bedding material passing through the mesh chain conveying mechanism. The first guide groove is inclined downward from left to right or from right to left. The second guide groove is disposed on the right or left side of the front part of the mesh chain conveying mechanism to receive bedding material leaving the first guide groove. The second guide groove is inclined downward from back to front.

[0007] As an improvement to the above solution, the upper part of the first guide groove is hinged to the frame, and the swing drive mechanism includes an eccentric wheel for contacting the lower side of the middle of the first guide groove and a drive motor for driving the eccentric wheel to rotate on the frame.

[0008] As an improvement to the above solution, the width of the eccentric wheel is greater than the width of the lower side of the first guide groove.

[0009] As an improvement to the above solution, a soft rubber layer is provided on the outer side of the eccentric wheel.

[0010] As an improvement to the above solution, the soft rubber layer is provided with a first guide groove extending into the relief groove.

[0011] As an improvement to the above solution, a counterweight block is provided on the lower side of the lower part of the first guide groove.

[0012] As an improvement to the above solution, the upper width of the first guide groove is greater than the bottom width of the groove.

[0013] As an improvement to the above solution, the width of the second guide groove is smaller than the width of the bottom of the first guide groove.

[0014] Implementing this utility model has the following beneficial effects:

[0015] The bedding material conveying device of this utility model, through the cooperation of a frame, a mesh chain conveying mechanism, a first guide trough, a second guide trough, a swing drive mechanism, and a recycling box, can receive and move the bedding material falling from the side of the cage box away from the mesh chain conveying mechanism, and automatically clean the first guide trough. Moreover, when cleaning the second guide trough, there is no need to stop the operation of the mesh chain conveying mechanism, thus ensuring the efficiency of bedding material addition.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to facilitate a clearer understanding of the technical concept claimed by the present invention. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit the present invention.

[0022] like Figures 1 to 4 As shown, a bedding material conveying device in an embodiment of the present invention includes a frame 1, a mesh chain conveying mechanism 2 for conveying cages from front to back, a first guide groove 3 for receiving bedding material, a second guide groove 4 installed on the frame 1, a swing drive mechanism 5 installed on the frame 1 for driving the first guide groove 3 to swing, and a recycling bin 6 installed below the discharge port on the front side of the second guide groove 4 for collecting bedding material. In practice, the mesh chain conveying mechanism 2 generally includes two sets of sprockets spaced back and forth, a mesh chain wound around the two sprockets, and a power motor that drives one of the sprockets to rotate. This makes the mesh chain approximately racetrack-shaped and divided into upper and lower layers. The upper mesh chain is used to convey the cage from front to back. Because the mesh chain has mesh holes, the scattered padding material can pass through the upper mesh chain and enter between the upper and lower layers of the mesh chain. In order to simplify the structure of the mesh chain conveying mechanism 2 and to more intuitively observe the first guide groove 3 and the swing drive mechanism 5, only the upper and lower layers of the mesh chain conveying mechanism 2 are shown in the accompanying drawings. This does not affect the understanding of the specific structure of the padding material conveying device of this utility model. The swing drive mechanism 5 can be a linkage mechanism combined with a motor, a telescopic cylinder, an electric telescopic rod, etc. The swing drive mechanism 5 drives the first guide groove 3 to swing, thereby causing the padding material in the first guide groove 3 to tilt and slide down along the unloading direction of the first guide groove 3.

[0023] The first guide groove 3 is located between the upper and lower layers of the front part of the mesh conveyor mechanism 2 to receive the padding material passing through the mesh conveyor mechanism 2. In fact, the upper width of the first guide groove 3 should be greater than the distance between the front and rear sides of the cage box, and it should be located directly below the discharge port of the external padding material adding machine to receive the padding material passing through the upper layer of the front part of the mesh conveyor mechanism 2 and to collect the padding material falling from the side of the cage box into the first guide groove 3.

[0024] The first guide groove 3 is inclined downwards from left to right or right to left. The second guide groove 4 is located on the right or left side of the front of the mesh conveyor mechanism 2 to receive the padding material leaving the first guide groove 3. The second guide groove 4 is inclined downwards from back to front. In practice, when the second guide groove 4 is located on the right side of the front of the mesh conveyor mechanism 2, the first guide groove 3 is inclined downwards from left to right. When the second guide groove 4 is located on the left side of the front of the mesh conveyor mechanism 2, the first guide groove 3 is inclined downwards from right to left. Under the guidance of the first guide groove 3, the padding material falls along the guiding direction of the first guide groove 3 into the range of the second guide groove 4 leaving the mesh conveyor mechanism 2. Under the action of the swing drive mechanism 5, the padding material accelerates its downward slide in the swinging first guide groove 3, preventing the padding material from accumulating and clogging the first guide groove 3.

[0025] The working principle of the bedding material conveying device of this utility model is as follows: When adding bedding material, if the bedding material falls from the side of the cage box, it will pass through the upper layer of the mesh chain conveyor 2 and fall into the first guide groove 3. Under the action of the swing drive mechanism 5, the first guide groove 3 accelerates the falling of the bedding material in the first guide groove 3 and makes the bedding material leave the mesh chain conveyor 2, and is guided into the recycling box 6 under the guidance of the second guide groove 4. At the same time, when it is necessary to clean the second guide groove 4, there is no need to stop the operation of the mesh chain conveyor 2. Just clean the second guide groove 4 and sweep the bedding material in the second guide groove 4 from back to back downward into the recycling box 6.

[0026] The bedding material conveying device of this utility model, through the cooperation of frame 1, mesh chain conveying mechanism 2, first guide groove 3, second guide groove 4, swing drive mechanism 5 and recycling box 6, can receive and move the bedding material falling from the side of the cage box away from the mesh chain conveying mechanism 2, and automatically clean the first guide groove 3. Moreover, when cleaning the second guide groove 4, there is no need to stop the operation of the mesh chain conveying mechanism 2, thus ensuring the efficiency of bedding material addition.

[0027] Specifically, such as Figure 1As shown, the upper part of the first guide groove 3 is hinged to the frame 1. The swing drive mechanism 5 preferably includes an eccentric wheel 7 for contacting the lower side of the middle of the first guide groove 3, and a drive motor 8 mounted on the frame 1 for driving the eccentric wheel 7 to rotate. In fact, the frame 1 extends into the space between the upper and lower layers of the mesh conveyor mechanism 2 to achieve the hinge with the upper part of the first guide groove 3 and to support the installation of the swing drive mechanism 5. The geometric center of the eccentric wheel 7 is eccentrically set with respect to the rotation center of the eccentric wheel 7. When the eccentric wheel 7 rotates, the distance between the outer side of the eccentric wheel 7 and the contact position of the lower side of the middle of the first guide groove 3 changes, thereby driving the first guide groove 3 to swing back and forth to facilitate the sliding of the padding material in the first guide groove 3.

[0028] More specifically, the width of the eccentric wheel 7 is preferably greater than the width of the lower side of the first guide groove 3. In fact, the width of the eccentric wheel 7 is the distance between the front and rear ends of the eccentric wheel 7, and the width of the lower side of the first guide groove 3 is the distance between the front and rear ends of the lower side of the first guide groove 3. The fact that the width of the eccentric wheel 7 is greater than the width of the lower side of the first guide groove 3 ensures that the eccentric wheel 7 can fully support the lower middle part of the first guide groove 3.

[0029] Furthermore, a soft rubber layer 9 is preferably provided on the outer side of the eccentric wheel 7. In fact, the soft rubber layer 9 can be made of materials such as rubber and silicone, which have a certain cushioning performance. Since the rotation speed of the eccentric wheel 7 and the falling speed of the first guide groove 3 when it swings may be different, the first guide groove 3 may collide with the eccentric wheel 7 when it swings down. By having the soft rubber layer 9 contact the lower side of the first guide groove 3, rigid collision between the first guide groove 3 and the eccentric wheel 7 is avoided, thus extending the service life of the first guide groove 3.

[0030] Furthermore, the soft rubber layer 9 is preferably provided for the first guide groove 3 to extend into the relief groove 10, thereby limiting the amplitude of the first guide groove 3's back-and-forth swing.

[0031] More specifically, a counterweight 11 is preferably provided on the lower side of the first guide groove 3. The counterweight 11 increases the weight of the lower part of the first guide groove 3, thereby increasing the torque exerted by the lower part of the first guide groove 3 on the eccentric wheel 7, and ensuring the degree of contact between the first guide groove 3 and the eccentric wheel 7 during the up-and-down swinging process.

[0032] It should be noted that the upper width of the first guide groove 3 is preferably greater than the bottom width, which serves to gather the pad material to the bottom of the first guide groove 3. Furthermore, the width of the second guide groove 4 is preferably smaller than the bottom width of the first guide groove 3, so that after the pad material is transferred from the bottom of the first guide groove 3 to the second guide groove 4, the sliding width is smaller, allowing the pad material to be more concentratedly introduced into the recycling bin 6.

[0033] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
