Description

Technical Field

[0001] This invention relates to the field of wildlife research equipment, specifically to a screening device for wildlife feces. Background Technology

[0002] In the field of wildlife research, fecal analysis is a crucial tool for understanding a wide range of information, including animal ecology, health status, and food preferences. Researchers have long collected wild animal fecal samples in the wild; however, untreated fecal samples often contain a large amount of impurities such as soil, sand, and plant debris, which greatly hinders accurate subsequent analysis. Wild animal feces are typically granular or clump-like, and some clumps are not firmly packed. When using common sieving equipment to remove surface debris, if the sieving frequency is too high or the sieving is too vigorous, the animal feces can easily scatter and pass through the sieve along with other debris, making it difficult to effectively remove the impurities.

[0022] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0023] 1. This invention provides a screening device for wild animal feces, which can slowly shake or lift the feces, causing debris on the surface of the feces to fall off and be automatically collected. Through the coordinated action of stabilizing and moving components, the feces are gently agitated, avoiding breakage and dispersion due to violent movements, thus ensuring the integrity of the feces sample for subsequent accurate research. This not only prevents excessively violent and rapid screening vibrations that could scatter the feces, but also avoids contamination of the working environment by debris.

[0024] 2. This invention, through the cooperation of a reciprocating screw and a connecting block, enables the moving component to move periodically relative to the stable component, achieving continuous screening. The reciprocating screw, a classic component of mechanical transmission, efficiently converts the rotational motion of the motor into the linear reciprocating motion of the connecting block, thereby precisely driving the moving component to form a rhythmic relative displacement with the stable component, continuously screening the feces and greatly improving screening efficiency.

[0025] 3. This invention utilizes the integrated first and second screening bars to avoid compressing fecal clumps and prevent the feces from scattering. The first and second screening bars are shaped to fit each other and are interlocked, which can effectively separate impurities while reserving appropriate space for the feces during relative movement, preventing excessive compression from damaging the original clump structure of the feces.

[0026] 4. The present invention, through the cooperation of the rotating plate and the first lever, enables the stabilizing component to rotate, thereby quickly realizing the dumping of feces and achieving unified transfer of feces. This avoids the feces from scattering due to manual cleaning and improves work efficiency.

[0027] 5. This invention can automatically unfold the plastic bag to receive feces while pouring, and retract the plastic bag after pouring, avoiding excessive space occupation by the equipment. Through the linkage of the rotating plate, the second lever, the rotating rod, and the crossbar, the plastic bag is opened to receive feces at the moment of starting pouring, and cleverly reset and retracted after completion, optimizing the use of the space around the equipment and facilitating its placement in small field research sites.

[0028] In summary, this invention can periodically and slowly shake or lift feces, causing debris to fall and be automatically collected, preventing feces from scattering and contaminating the environment, ensuring sample integrity, and improving efficiency. It can also quickly dump and uniformly transfer feces, automatically unfolding plastic bags to catch the feces during dumping and retracting them afterward, optimizing space utilization and making it suitable for confined outdoor spaces.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0048] like Figures 1 to 10 As shown, the wildlife feces screening device includes: a shell 1, an inner frame 101, a stabilizing component 2, a moving component 3, and a drive mechanism.

[0049] refer to Figure 1 and Figure 2 An inner frame 101 is installed inside the outer casing 1. A collection box 102 is installed at the bottom of the inner frame 101. The collection box 102 is a hollow cavity structure with an open top, used to collect screened debris. A stabilizing component 2 is installed on the inner frame 101, and a movable component 3 is installed inside the inner frame 101. The movable component 3 is controlled by a drive mechanism and can move relative to the stabilizing component 2. When the stabilizing component 2 and the movable component 3 move relative to each other, the animal feces located at the top of the stabilizing component 2 can be slowly shaken through their mutual cooperation, causing surface debris to fall off, while avoiding excessively violent or rapid movement that could cause the feces to scatter. (Reference) Figure 3 and Figure 4 The stabilizing component 2 includes: a first screening bar 201 and a first screening slot 202. There are several first screening bars 201. The portion of the first screening bar 201 located within the inner frame 101 consists of an inclined portion and a horizontal portion, with the included angle between these two portions being an obtuse angle between 120° and 150°. Several first screening bars 201 are equidistantly installed on the inner frame 101, and a first screening slot 202 is formed between adjacent first screening bars 201. The movable component 3 includes: a second screening bar 301, a second screening slot 302, a connecting rod 303, and a positioning rod 304. There are several second screening bars 301, equidistantly arranged, and a second screening slot 302 is formed between adjacent second screening bars 301. The shape of the second screening bar 301 is adapted to the first screening bar 201, and the width of the second screening bar 301 is adapted to the width of the first screening slot 202. Several first screening bars 201 and several second screening bars 301 are staggered. When the stabilizing component 2 and the moving component 3 undergo relative displacement, the first screening bars 201 and the second screening bars 301 can be interlocked without interfering with each other. Several equidistant second screening bars 301 are connected by connecting rods 303 to ensure that the second screening bars 301 form a whole, and the connecting rods 303 are located at the bottom of the first screening bars 201. The two ends of the connecting rods 303 extend into the second screening bars 301 located on both sides. A positioning rod 304 is installed on the second screening bar 301 located on the rear side.

[0050] refer to Figure 9 and Figure 10 As shown, the drive mechanism includes: a first groove 4, a second groove 5, a slider 6, a limiting block 601, a moving frame 7, a limiting groove 701, a connecting block 8, a mounting bracket 9, a reciprocating screw 10, a motor 11, and a positioning beam 12. The first groove 4 is located on the rear side of the outer casing 1. The rear end of the connecting rod 303 and the positioning rod 304 extend into the first groove 4. The first groove 4 can simultaneously limit the connecting rod 303 and the positioning rod 304, thereby ensuring that the angle and position of the movable component 3 can be controlled and limited when it moves. The second groove 5 is located on the front side of the outer casing 1. The front end of the connecting rod 303 extends into the second groove 5. The second groove 5 limits the connecting rod 303, ensuring stability during movement. The slider 6 is installed at the front end of the connecting rod 303. Two limiting blocks 601 are installed on the slider 6, symmetrically arranged relative to the slider 6. The moving frame 7 is installed on the outside of the slider 6. Two limiting grooves 701 are formed within the movable frame 7, symmetrically arranged relative to the movable frame 7, and two limiting blocks 601 are slidably installed within the two limiting grooves 701. A connecting block 8 is installed on the movable frame 7. Two mounting brackets 9 are symmetrically installed on the outer casing 1. A reciprocating screw 10 is rotatably installed between the two mounting brackets 9. The connecting block 8 is threadedly connected to the reciprocating screw 10. The reciprocating screw 10 is an existing device, characterized by two threaded grooves with the same pitch but opposite directions of rotation. The connecting block 8 has a slider adapted to the threaded groove, which is embedded within the groove. When the reciprocating screw 10 rotates, it can drive the connecting block 8 to reciprocate without changing the direction of rotation. The length of the threaded groove on the reciprocating screw 10 is adapted to the first groove body 4 and the second groove body 5. A motor 11 is installed on one of the mounting brackets 9, and the output end of the motor 11 is connected to one end of the reciprocating screw 10. Turning on the motor 11 drives the reciprocating screw 10 to rotate. The positioning beam 12 is installed between the two mounting brackets 9, and the positioning beam 12 passes through the connecting block 8. The positioning beam 12 can limit the movement of the connecting block 8 and prevent it from rotating. (Reference) Figure 7 and Figure 8 The first tank 4 includes a first smooth section 401, a first inclined section 402, and a second inclined section 403, and the first smooth section 401, the first inclined section 402, and the second inclined section 403 are interconnected. The second tank 5 includes a second smooth section 501 and a third inclined section 502, and the second smooth section 501 and the third inclined section 502 are interconnected.

[0051] The specific working principle of the above structure is as follows: Feces are placed on each of the first screening bars 201. The motor 11 is started, driving the reciprocating screw 10 to rotate, which in turn drives the connecting block 8 and the moving frame 7 to move along the axial direction of the reciprocating screw 10. At this time, the slider 6 moves synchronously with the moving frame 7, and the mutual limiting action of the limiting block 601 and the limiting groove 701 ensures that the slider 6 can only move in the up and down direction. Meanwhile, the two ends of the connecting rod 303 slide in the second smooth section 501 and the first smooth section 401 respectively, and multiple second screening bars 301 move synchronously towards the stabilizing component 2. Simultaneously, the positioning rod 304 also moves in the first smooth section 401. As the second screening bars 301 move, the positioning rod 304 slides from the first smooth section 401 into the second inclined section 403, thereby causing the second screening bars 301 to rotate and tilt to achieve... Figure 5 The state of the feces is passively lifted or shaken. Then, the connecting block 8 moves in the reverse direction, the second screening bar 301 resets, and as the connecting block 8 continues to move, both ends of the connecting rod 303 enter the first inclined section 402 and the third inclined section 502 respectively, while the positioning rod 304 remains in the first smooth section 401. At this time, the second screening bar 301 is... Figure 6 As shown in the diagram. Through the periodic cycle described above, the feces can be continuously and slowly lifted or shaken, causing surface debris to be shaken off. At the same time, during this process, the debris will fall into the collection box 102 through the first sieve 202 and the second sieve 302.

[0052] The aforementioned structure allows for the slow shaking or lifting of feces during use, causing debris on the surface to fall off and be automatically collected. This not only prevents excessively violent and rapid screening vibrations that could cause the feces to scatter, but also avoids debris contaminating the working environment. Furthermore, the cooperation of the reciprocating screw 10 and the connecting block 8 enables the movable component 3 to periodically move relative to the stable component 2, achieving continuous screening. Simultaneously, the integrated first screening bar 201 and second screening bar 301 prevent the compression of fecal clumps and avoid the feces from scattering. Moreover, all of the above structures are implemented mechanically, offering high stability and precision, and facilitating operation.

[0053] After screening, the fecal clumps need to be transferred to collection bags for subsequent research. However, since most wild animal fecal clumps are relatively soft and have low clumping, manual transfer is inconvenient, and sorting granular wild animal feces is also difficult. Therefore, this invention also proposes the following solution: (See reference) Figures 11 to 13 The stabilizing component 2 is rotatably mounted on the inner frame 101 via a pivot; a tilting mechanism 13 is installed on the outer shell 1, which is controlled to flip the stabilizing component 2 and thus dump the fecal mass on the stabilizing component 2.

[0054] refer to Figure 12 and Figure 13The tilting mechanism 13 includes: a first lever 131, a first mounting plate 132, a rotating plate 133, a first through groove 134, a pull rod 135, a second mounting plate 136, a second through groove 137, a rotating rod 138, a second lever 139, a crossbar 1310, and a fixing groove 1311.

[0055] The first lever 131 is mounted on the foremost first screening bar 201, and is not coaxial with the rotating shaft of the stabilizing component 2. Pulling the first lever 131 causes the stabilizing component 2 to rotate. The first mounting plate 132 is mounted on the outer casing 1. The rotating plate 133 is rotatably mounted on the first mounting plate 132. The first through groove 134 is formed on the rotating plate 133, and the first lever 131 extends into the first through groove 134. When the rotating plate 133 rotates, the first through groove 134 limits the first lever 131, allowing the first lever 131 to drive the stabilizing component 2 to rotate. At the same time, the first lever 131 slides in the first through groove 134 to avoid interference. The pull rod 135 is mounted on the rotating plate 133. Pulling the pull rod 135 causes the rotating plate 133 to rotate, facilitating operation by the staff. The second mounting plate 136 is mounted on the outer casing 1. The second through groove 137 is formed on the rotating plate 133. The rotating rod 138 is rotatably mounted on the second mounting plate 136. A second lever 139 is mounted on the rotating rod 138 and extends into the second through slot 137. When the rotating plate 133 rotates, the second through slot 137 acts on the second lever 139, causing the rotating rod 138 to rotate. A crossbar 1310 is mounted on the rotating rod 138 and located at the end furthest from the second lever 139. A fixing slot 1311 is mounted on the outer casing 1. In use, the crossbar 1310 and the fixing slot 1311 work together to fix the collection bag. The collection bag can be a common plastic bag; simply attach or place the opening edge of the plastic bag onto the crossbar 1310 and the fixing slot 1311.

[0056] The specific working principle of the above structure is as follows: When it is necessary to pour the sifted fecal clumps from the stabilizing component 2 into the collection bag, the worker pulls the lever 135 installed on the rotating plate 133 to start rotating the rotating plate 133. When the rotating plate 133 rotates, the first through groove 134 limits the first lever 131, causing the stabilizing component 2 to rotate around its axis. At the same time, the first lever 131 slides in the first through groove 134, avoiding interference between components, thereby allowing the fecal clumps at the top of the stabilizing component 2 to be poured out. Simultaneously, as the rotating plate 133 rotates, the second through groove 137 applies force to the second lever 139, causing the rotating rod 138 to rotate, which in turn causes the crossbar 1310 to rotate, causing the plastic bag opening to open laterally and receive the poured fecal clumps. After the clumps are poured out, the rotating plate 133 resets, the stabilizing component 2 resets, and the crossbar 1310 resets, closing the plastic bag opening.

[0057] The aforementioned structure enables rapid and unified disposal of feces, avoiding the scattering caused by manual cleaning and improving work efficiency. Furthermore, the structure automatically unfolds the plastic bag to receive the feces while disposing of it and retracts it upon completion, minimizing the equipment's footprint.

[0058] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
