Description

Technical Field

[0001] The present invention relates to the field of wild animal research equipment, and specifically refers to a screening device for wild animal feces. Background Art

[0002] In the field of wild animal research, fecal analysis is a key means to understand various information such as animal ecology, health status, and food preferences. Researchers have been collecting wild animal fecal samples in the wild for a long time. However, the surface of untreated fecal samples is mixed with a large number of impurities such as soil, sand, and plant residues, which brings great obstacles to subsequent accurate analysis. Generally, wild animal feces are in a granular or lumpy state, and some feces lumps are not firm. When using common screening equipment to clean the surface debris, if the screening device has too high a frequency and violent screening movement, it is very easy to cause the animal feces to disperse, and then pass through the sieve mesh together with the debris during the screening movement, making it difficult to effectively screen out the debris.

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

[0023] 1. A screening device for wild animal feces provided by the present invention can realize slow shaking or jacking of the feces, so that sundries on the surface of the feces fall off, and the feces are automatically collected. Through the coordinated action of the stable component and the movable component, the feces are gently disturbed, avoiding the fragmentation and dispersion of the feces caused by violent actions, ensuring the integrity of the fecal sample for subsequent precise research. It can not only prevent the screening vibration from being too violent and fast to disperse the feces, but also avoid sundries from polluting the working environment.

[0024] 2. Through the cooperation of the reciprocating lead screw and the connecting block, the present invention can make the movable component move relative to the stable component periodically, realizing continuous screening. As a classic component of mechanical transmission, the reciprocating lead screw efficiently converts the rotational motion of the motor into the linear reciprocating motion of the connecting block, thereby accurately driving the movable component to form a rhythmic relative displacement with the stable component, continuously performing screening operations on the feces, and greatly improving the screening efficiency.

[0025] 3. By using the cooperation of the integral first screening bar and the second screening bar, the present invention avoids squeezing the fecal mass and prevents the feces from spreading. The first screening bar and the second screening bar are in shape adaptation and are inserted in an alternating manner. When moving relative to each other, they can not only effectively separate sundries, but also reserve a suitable space for the feces, preventing the original lump structure of the feces from being damaged by excessive extrusion.

[0026] 4. Through the cooperation of the rotating plate and the first lever, the present invention can make the stable component rotate, thus quickly realizing the tipping of the feces, achieving the unified transfer of the feces, avoiding the dispersion of the feces caused by manual step-by-step cleaning of the feces, and being beneficial to improving work efficiency.

[0027] 5. The present invention can automatically unfold the plastic bag for receiving feces while dumping feces, and fold the plastic bag after dumping, so as to avoid the equipment occupying too much space. Through the linkage of the rotating plate, the second lever, the rotating rod and the cross bar, the plastic bag is opened to prepare for receiving feces at the moment of starting dumping, and is cleverly reset and folded after dumping, so as to optimize the use of space around the equipment and facilitate its placement in a narrow field research site.

[0028] In summary, the present invention can periodically shake or lift up the feces slowly, allowing debris to fall and be automatically collected, preventing the feces from spreading and the environment from being polluted, ensuring the integrity of the sample, and improving efficiency. It can also quickly dump the feces and transfer them uniformly, and can automatically unfold the plastic bag to receive the feces when dumping, and fold it up after dumping, optimizing space utilization, and is suitable for small outdoor sites.

Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this text generally represents an "or" relationship between the associated objects before and after.

[0048] As Figures 1 to 10 shown, the screening device for wild animal feces includes: a housing 1, an inner frame 101, a stabilizing component 2, a movable component 3, and a driving mechanism.

[0049] Referring to Figure 1 and Figure 2 , the inner frame 101 is installed inside the housing 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, and is used to receive the sifted debris. The stabilizing component 2 is installed on the inner frame 101, and the movable component 3 is installed inside the inner frame 101. The movable component 3 can move relative to the stabilizing component 2 under the control of the driving mechanism. When the stabilizing component 2 and the movable component 3 move relative to each other, through their mutual cooperation, the animal feces located at the top of the stabilizing component 2 can be slowly shaken, so that the debris on the surface falls off, and at the same time, it is avoided that the slow movement is too violent or fast, resulting in the feces being scattered. Referring to Figure 3 and Figure 4 , the stabilizing component 2 includes: a first screening strip 201 and a first screening slot 202. There are several first screening strips 201. The part of the first screening strip 201 located in the inner frame 101 is composed of an inclined part and a horizontal part, and the included angle between the two parts is set as an obtuse angle, and the angle is between 120° and 150°. Several first screening strips 201 are respectively installed on the inner frame 101 at equal intervals, and a first screening slot 202 is formed between two adjacent first screening strips 201. The movable component 3 includes: a second screening strip 301, a second screening slot 302, a connecting rod 303, and a positioning rod 304. There are several second screening strips 301, and they are respectively arranged at equal intervals. A second screening slot 302 is formed between two adjacent second screening strips 301. The shape of the second screening strip 301 is adapted to that of the first screening strip 201, and the width of the second screening strip 301 is adapted to the width of the first screening slot 202. Several first screening strips 201 and several second screening strips 301 are arranged in an interleaved manner. When the stabilizing component 2 and the movable component 3 move relative to each other, each first screening strip 201 and the second screening strip 301 can be inserted into each other without mutual interference. Several second screening strips 301 arranged at equal intervals are connected by a connecting rod 303 to ensure that each second screening strip 301 forms a whole, and the connecting rod 303 is located at the bottom of the first screening strip 201. Both ends of the connecting rod 303 respectively extend out of the second screening strips 301 on both sides. The positioning rod 304 is installed on the second screening strip 301 located at the rear side.

[0050] Reference Figure 9 and Figure 10 As shown, the driving mechanism includes: a first groove body 4, a second groove body 5, a slider 6, a limit block 601, a moving frame 7, a limit groove 701, a connecting block 8, a mounting bracket 9, a reciprocating lead screw 10, a motor 11, and a positioning beam 12. The first groove body 4 is opened at the rear side of the housing 1, and the rear end of the connecting rod 303 and the positioning rod 304 extend into the first groove body 4. The first groove body 4 can limit the connecting rod 303 and the positioning rod 304 at the same time, so as to ensure that when the moving component 3 moves, the angle and position of the moving component 3 can be controlled and limited. The second groove body 5 is opened at the front side of the housing 1, and the front end of the connecting rod 303 extends into the second groove body 5. The second groove body 5 limits the connecting rod 303 to ensure stability during movement. The slider 6 is installed at the front end of the connecting rod 303. The limit block 601 is installed on the slider 6. There are two limit blocks 601, which are symmetrically arranged relative to the slider 6. The moving frame 7 is installed outside the slider 6. The limit groove 701 is opened in the moving frame 7. There are two limit grooves 701, which are symmetrically arranged relative to the moving frame 7, and the two limit blocks 601 are slidably installed in the two limit grooves 701. The connecting block 8 is installed on the moving frame 7. There are two mounting brackets 9, which are symmetrically installed on the housing 1. The reciprocating lead screw 10 is rotatably installed between the two mounting brackets 9. The connecting block 8 is threadedly connected to the reciprocating lead screw 10. The reciprocating lead screw 10 is an existing device, which is characterized by two thread grooves with the same pitch and opposite helix directions. The connecting block 8 is provided with a slider adapted to the thread groove, and the slider is embedded in the thread groove. When the reciprocating lead screw 10 rotates, it can drive the connecting block 8 to reciprocate without changing the rotation direction. And the length of the thread groove opened on the reciprocating lead screw 10 is adapted to the first groove body 4 and the second groove body 5. The 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 lead screw 10. Starting the motor 11 can drive the reciprocating lead screw 10 to rotate. The positioning beam 12 is installed between the two mounting brackets 9, and the positioning beam 12 penetrates through the connecting block 8. The positioning beam 12 can limit the connecting block 8 to prevent the connecting block 8 from rotating by itself. Reference Figure 7 and Figure 8 , the first groove body 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 groove body 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: The feces are placed on each first screening bar 201. The motor 11 is started to drive the reciprocating lead screw 10 to rotate, driving the connecting block 8 and the moving frame 7 to move along the axial direction of the reciprocating lead screw 10. At this time, the slider 6 moves synchronously with the moving frame 7, and the mutual limiting effect of the limiting block 601 and the limiting groove 701 is used to ensure that the slider 6 can only move in the up and down directions. At this time, both 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 stable component 2. At the same time, the positioning rod 304 also moves in the first smooth section 401. As the second screening bar 301 moves, the positioning rod 304 slides from the first smooth section 401 into the second inclined section 403, thereby causing the second screening bar 301 to rotate and tilt to reach Figure 5 the state, and making the feces be pushed up passively or shaken. Subsequently, the connecting block 8 moves reversely, and the second screening bar 301 resets. 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 stays in the first smooth section 401. At this time, the second screening bar 301 is in the Figure 6 state shown. Through the periodic cycle of the above method, the feces can be continuously pushed up or shaken slowly, so that the surface sundries are shaken off. At the same time, the sundries will fall into the collection box 102 through the first sieve slot 202 and the second sieve slot 302 during this process.

[0052] The above structure can realize the slow shaking or pushing up of the feces during use, so that the sundries on the surface of the feces fall off and are automatically collected. It can not only prevent the feces from spreading due to overly violent and rapid screening vibration, but also avoid the sundries from polluting the working environment. In addition, through the cooperation of the reciprocating lead screw 10 and the connecting block 8, the movable component 3 can move relative to the stable component 2 periodically, realizing continuous screening. At the same time, the cooperation of the integral first screening bar 201 and the second screening bar 301 is used to avoid squeezing the feces mass and prevent the feces from spreading. Moreover, the above structure is realized through mechanical structures, which have high stability and accuracy and are conducive to operation.

[0053] When the screening is over, the feces mass needs to be transferred to a collection bag for subsequent research. However, since most of the wild animal feces masses are relatively soft and have a low degree of agglomeration, manual transfer is not conducive to operation, and the sorting of granular wild animal feces is also relatively inconvenient. Therefore, the present invention also proposes the following solution: Refer to Figures 11 to 13 , the stable component 2 is rotatably installed on the inner frame 101 through a rotating shaft; a tipping mechanism 13 is installed on the outer shell 1, and the tipping mechanism 13 is controlled to be able to turn over the stable component 2, thereby tipping the feces mass on the stable component 2.

[0054] Refer to Figure 12 and Figure 13, the tipping 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 cross bar 1310 and a fixing groove 1311.

[0055] The first lever 131 is mounted on the first screening bar 201 at the forefront, and the first lever 131 is not coaxial with the rotating shaft of the stabilizing assembly 2. Pulling the first lever 131 can make the stabilizing assembly 2 rotate. The first mounting plate 132 is mounted on the housing 1. The rotating plate 133 is rotatably mounted on the first mounting plate 132. The first through groove 134 is formed in 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 can limit the first lever 131, enabling the first lever 131 to drive the stabilizing assembly 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 can make the rotating plate 133 rotate, facilitating the operation of the staff. The second mounting plate 136 is mounted on the housing 1. The second through groove 137 is formed in the rotating plate 133. The rotating rod 138 is rotatably mounted on the second mounting plate 136. The second lever 139 is mounted on the rotating rod 138, and the second lever 139 extends into the second through groove 137. When the rotating plate 133 rotates, the second through groove 137 acts on the second lever 139, enabling the rotating rod 138 to rotate. The cross bar 1310 is mounted on the rotating rod 138 and is located at the end far from the second lever 139. The fixing groove 1311 is mounted on the housing 1. During use, the cross bar 1310 and the fixing groove 1311 work together to fix the collection bag. The collection bag can use common plastic bags on the market. Just stick or put the opening edge of the plastic bag on the cross bar 1310 and the fixing groove 1311.

[0056] The specific working principle of the above structure is as follows: When it is necessary to pour the screened fecal mass on the stabilizing assembly 2 into the collection bag, the staff pulls the pull rod 135 mounted on the rotating plate 133 to make the rotating plate 133 start to rotate. When the rotating plate 133 rotates, the first through groove 134 has a limiting effect on the first lever 131, driving the stabilizing assembly 2 to rotate around its rotating shaft. At the same time, the first lever 131 slides in the first through groove 134, avoiding interference between components, so as to realize the tipping of the feces at the top of the stabilizing assembly 2. At the same time, when the rotating plate 133 rotates, the second through groove 137 exerts a force on the second lever 139, making the rotating rod 138 rotate, and then making the cross bar 1310 rotate accordingly, so that the opening of the plastic bag is horizontally unfolded to receive the poured feces. After the tipping contact, the rotating plate 133 resets, the stabilizing assembly 2 resets, and at the same time the cross bar 1310 resets, and the plastic bag opening closes.

[0057] When the above structure is used, the feces can be quickly dumped and uniformly transferred, avoiding the feces being scattered due to manual cleaning, which is conducive to improving work efficiency. In addition, the structure automatically unfolds the plastic bag that receives the feces while dumping the feces, and closes the plastic bag after dumping, avoiding the equipment from occupying too much space.

[0058] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
