Description

Technical Field

[0001] The invention relates to the technical field of chicken cage component performance detection, in particular to a stacked chicken cage component detection device. Background Art

[0002] The stacked chicken cage is made of multiple layers of cages and is used for laying hens. The bottom net of each layer of the stacked chicken cage is tilted to facilitate the automatic sliding and collection of eggs, preventing the eggs from staying at the bottom of the cage and causing contamination or damage. Usually, the tilt angle of the bottom of the chicken cage is generally between 5° and 8°, but it may also vary according to specific designs and needs.

[0003] During the production process of stacked chicken cages, it is necessary to test whether the eggs can be safely collected. The correct tilt angle of the bottom of the chicken cage can ensure that the eggs slide smoothly to the collection device, and at the same time ensure the comfort of the chickens standing and lying, and avoid excessive tilt causing discomfort to the chickens. In addition, the material and surface treatment of the cage are also very important. The surface needs to be smooth to facilitate the rolling of eggs, but it must be prevented from being too smooth to cause the chickens to stand unsteadily.

[0004] Usually, during the testing process, the bottom nets of different materials are tilted at different angles, and then the breakage rate of the eggs when they slide down is observed. The test results obtained in this way are inaccurate: in normal use, the bottom net will be subjected to pressure from the chicken, and the deformation of the bottom net will also affect the speed at which the eggs slide down. Therefore, the test results are not comprehensive and close to the actual usage; and the existing testing methods usually test single items separately, without sufficient contrast, and the test items are relatively single, resulting in inaccurate test results.

[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0039] like Figure 1 As shown, a stacked chicken cage assembly detection device includes a base 1, a bottom net 6 is arranged above the base 1, a plurality of mounting mechanisms 3 evenly distributed left and right for placing the bottom net 6 are arranged on the upper surface of the base 1, and a squeezing mechanism 2 for detecting the bearing capacity of the bottom net 6, the squeezing mechanism 2 is arranged on the mounting mechanism 3, the detection device also includes a second adjustment mechanism 5 for adjusting the inclination angle of the bottom net 6, the second adjustment mechanism 5 is arranged on the upper surface of the base 1 and is located at the front side of the mounting mechanism 3, the detection device also includes a first adjustment mechanism 4 for linking the plurality of second adjustment mechanisms 5, and the first adjustment mechanism 4 is arranged on the upper surface of the base 1.

[0040] like Figure 1 and Figure 2 As shown, the mounting mechanism 3 includes a support member 32 arranged on the upper surface of the base 1, on which two left-right symmetrical clamping members 33 are arranged, and a feeding member 34 is commonly arranged on the two clamping members 33, and a storage basket 31 is fixedly connected to the rear side of the support member 32.

[0041] like Figure 2 and Figure 4 As shown, the support member 32 includes a mounting seat 326 fixedly connected to the upper surface of the base 1, the storage basket 31 is fixedly connected to the rear surface of the mounting seat 326, the upper surface of the mounting seat 326 is hinged with a supporting plate 321, a limiting sleeve 323 is fixedly connected at the middle position of the lower surface of the supporting plate 321, and a connecting strip 324 is slidably connected to the left and right at the middle position of the lower surface of the supporting plate 321.

[0042] like Figure 2 and Figure 3 As shown, the clamping member 33 includes a fixing plate 332 fixedly connected to the upper surface of the supporting plate 321, and mounting grooves are provided on the opposite surfaces of the two fixing plates 332. A plurality of connecting columns 331 are elastically slidably connected to the upper surface of the mounting grooves, and the bottom ends of the plurality of connecting columns 331 are commonly fixedly connected to an extrusion plate 333, and the front ends of the extrusion plate 333 and the mounting grooves are both arc-shaped chamfered.

[0043] When testing the safe collection of eggs on the bottom net 6, the bottom net 6 is first installed. The bottom net 6 is inserted from the front ends of the two fixed plates 332 to the bottom of the extrusion plate 333, and the bottom net 6 is pushed backward to the rear end of the mounting groove on the fixed plate 332. At the same time, the bottom net 6 generates an upward thrust on the extrusion plate 333. Since the connecting column 331 and the fixed plate 332 are elastically slidably connected, when the extrusion plate 333 is pushed upward by the upward thrust and the connecting column 331 is pushed upward, the extrusion plate 333 generates a reverse force on the bottom net 6 under the action of the elastic force, and the bottom net 6 is pressed tightly inside the mounting grooves of the two fixed plates 332. The remaining installation methods of the bottom net 6 are the same as the above steps.

[0044] It should be noted that when installing multiple bottom nets 6, you can choose to install multiple bottom nets 6 of the same material, or you can choose to install multiple bottom nets 6 of different materials. Reasonable matching can be carried out according to detection needs to facilitate comparative detection.

[0045] like Figure 1 and Figure 5 As shown, the first adjustment mechanism 4 includes an adjustment member 41, a transmission member 42 and a pushing member 43 which are arranged in sequence from back to front on the left side of the upper surface of the base 1. A linkage member 44 for linking the adjustment member 41 and the pushing member 43 is arranged on the base 1. There are multiple transmission members 42 and they correspond one-to-one to the mounting mechanism 3.

[0046] like Figure 4 As shown, the connecting bar 324 passes through the limiting sleeve 323 on the left and right sides, and the left and right ends of the connecting bar 324 are fixedly connected with magnetic strips 322. The lower surface of the connecting bar 324 is fixedly connected with two front-to-back symmetrical connecting slide rods 325. The connecting slide rods 325 are slidably connected to the limiting sleeve 323 on the left and right sides, and the magnetic strips 322 at adjacent positions of multiple supporting plates 321 are adsorbed on each other.

[0047] like Figure 5 and Figure 6 As shown, the adjusting member 41 includes two left-right symmetrical fixing seats 414 fixedly connected to the upper surface of the base 1, and the two fixing seats 414 are connected to the screw rod 411 for common rotation, the left end of the screw rod 411 penetrates to the left side surface of the left fixing seat 414 and is fixedly connected to the first turntable, a pushing block 413 is threadedly connected on the circumferential surface of the screw rod 411 and located between the opposite surfaces of the two fixing seats 414, and a limiting slide bar 412 is fixedly connected between the opposite surfaces of the two fixing seats 414 and located below the screw rod 411, the pushing block 413 is connected to the limiting slide bar 412 for left-right sliding connection, and a telescopic connecting rod 415 is hinged on the upper surface of the pushing block 413, and the end of the telescopic connecting rod 415 away from the pushing block 413 is hinged to the lower surface of the leftmost magnetic attraction strip 322.

[0048] In specific use, after the installation of the bottom net 6 is completed, the inclination angle of the bottom net 6 begins to be adjusted. The screw rod 411 is driven to rotate by rotating the first turntable, and the screw rod 411 drives the pushing block 413 to slide left and right on the limiting slide bar 412. During the sliding process, the pushing block 413 drives the leftmost magnetic strip 322 to move synchronously through the telescopic connecting rod 415. At this time, the leftmost connecting strip 324 moves synchronously, and drives the connecting slide bar 325 to slide on the limiting sleeve 323. When the magnetic strip 322 at the right end of the leftmost connecting strip 324 moves, the magnetic strip 322 on the adjacent carrying plate 321 is synchronously driven to move left and right through its magnetic attraction. When the magnetic strip 322 drives the connecting strip 324 When the limit sleeve 323 moves to the right until the left end of the connecting slide bar 325 abuts against the left end of the limit sleeve 323, the left and right ends of the left and right magnetic strips 322 coincide with the left and right ends of the supporting plate 321 respectively. At this time, the multiple supporting plates 321 are in an independent state and can be independently adjusted in angle; when the magnetic strip 322 drives the connecting strip 324 to move to the right on the limit sleeve 323 until the left end of the connecting slide bar 325 abuts against the left end of the limit sleeve 323, the magnetic strip 322 on the right side slides to under the supporting plate 321 on the right side.

The lower friction plate 424 is slid to the left on the spline shaft of the transmission connecting shaft 423. At the same time, since the reset column 426 and the transmission connecting shaft 423 are elastically slidably connected, the reset column 426 drives the friction plate 424 away from the mushroom-shaped connecting shaft 422 under the action of elastic force. At this time, when the mushroom-shaped connecting shaft 422 rotates, it will not drive the friction plate 424 to rotate, and then will not drive the corresponding transmission connecting shaft 423 to rotate. The multiple second adjustment mechanisms 5 are in an independent state. On the contrary, when the friction plate 424 is tightly attached to the mushroom-shaped connecting shaft 422, under the action of friction force, the friction plate 424 rotates synchronously with the mushroom-shaped connecting shaft 422, and the multiple second adjustment mechanisms 5 are in a linkage state.

[0057] like Figure 7As shown, the lifting member 52 includes a threaded rod 521 rotatably connected to the upper surface of the second transmission box 514, the upper surface of the second transmission box 514 and located at the front side of the threaded rod 521 is fixedly connected to a limited sliding column 524, a push plate 522 is threadedly connected to the circumferential surface of the threaded rod 521, the push plate 522 is slidably connected to the limited sliding column 524 up and down, the upper surface of the push plate 522 and located on the left and right sides of the threaded rod 521 are fixedly connected to a top column 523, the top of the top column 523 is slidably matched with the lower surface of the corresponding bearing plate 321, the rear end of the transmission shaft 513 passes through the interior of the second transmission box 514, the bottom end of the threaded rod 521 passes through the interior of the second transmission box 514 and is connected to the transmission shaft 513 through a bevel gear transmission (such as Fig.10 as shown).

[0058] In specific use, when multiple supporting plates 321 are in an independent state, the second adjustment mechanism 5 corresponding to the supporting plates 321 is also in an independent state, and the driving shaft 513 is driven to rotate synchronously through the bevel gear by rotating the oscillating plate 512. At this time, the driving shaft 513 also drives the threaded rod 521 to rotate on the second transmission box 514 through the bevel gear, thereby driving the push plate 522 to slide up and down, and the supporting plate 321 is pushed to deflect on the mounting seat 326 through the top column 523, so as to independently adjust the inclination angle of the supporting plate 321; when multiple supporting plates 321 are connected, When in the dynamic state, the second adjustment mechanism 5 corresponding to the supporting plate 321 is linked through multiple transmission parts 42. At this time, the mushroom-shaped connecting shaft 422 is driven to rotate by rotating the second turntable on the leftmost transmission connecting shaft 423. The mushroom-shaped connecting shaft 422 can drive the adjacent transmission connecting shaft 423 to rotate synchronously. At the same time, the transmission connecting shaft 423 drives the transmission shaft 513 to rotate synchronously through the bevel gear, so as to link and adjust the inclination angle of the supporting plate 321. According to the detection needs, it is selected whether multiple supporting plates 321 are linked and adjusted to facilitate comparative detection.

[0059] like Figure 1 and Fig.11 As shown, the extrusion mechanism 2 includes support feet 23 symmetrically installed on the upper surface of the fixed plate 332, the top ends of the four support feet 23 are commonly fixedly connected to the support plate 22, the upper surface of the support plate 22 is fixedly connected to the electric telescopic rod 21, and the four support feet 23 are commonly connected to a metal sliding plate 24 for sliding up and down. The telescopic end of the electric telescopic rod 21 penetrates to the lower surface of the support plate 22 and is fixedly connected to the upper surface of the metal sliding plate 24, and a plurality of magnetic extrusion blocks 25 are adsorbed on the lower surface of the metal sliding plate 24.

[0060] During specific use, after adjusting the inclination angle of the bottom net 6, the electric telescopic rod 21 is extended to push the metal sliding plate 24 to move downward, and the magnetic extrusion block 25 on the lower surface of the metal sliding plate 24 generates a downward extrusion force on the bottom net 6 to simulate the pressure exerted by the chicken on the bottom net 6. The electric telescopic rod 21 is reciprocated to repeatedly perform pressure tests on the bottom net 6.

[0061] It should be noted that the magnetic extrusion blocks 25 of different diameters can be replaced for extrusion force testing. At the same time, different numbers of magnetic extrusion blocks 25 can be selected and extrusion force tests can be performed at different positions on the metal sliding plate 24, so as to more realistically simulate the situation of the chicken on the bottom net 6. According to the detection needs, a reasonable reciprocating frequency can be selected and matched with the above-mentioned magnetic extrusion blocks 25 to simulate the pressure state of the bottom net 6 when the chicken is on the bottom net 6.

[0062] like Figure 2 and Fig.12 As shown, the feeding member 34 includes a lower hopper 345 hinged together on the front ends of the upper surfaces of two fixed plates 332, a gate-shaped support frame 341 is fixedly connected to the upper surface of the base 1 and located in front of the lower hopper 345, a first sliding block 342 is connected to the vertical section of the gate-shaped support frame 341 for sliding up and down movement, and connecting blocks 343 are hinged on the opposite surfaces of the two first sliding blocks 342, a connecting auxiliary rod 344 is connected to the connecting block 343 for sliding back and forth movement, and the rear end of the connecting auxiliary rod 344 is hinged to the front surface of the lower hopper 345, the first sliding block 342 and the vertical section of the gate-shaped support frame 341 and the connecting auxiliary rod 344 and the connecting block 343 are all frictionally matched, and when not subject to external force, the first sliding block 342 remains stationary on the vertical section of the gate-shaped support frame 341, and the connecting auxiliary rod 344 remains stationary inside the connecting block 343.

[0063] During specific use, eggs are put into the lower hopper 345, and the eggs slide through the bottom of the lower hopper 345 to the bottom net 6, and roll from the bottom net 6 from front to back to the support 32 for egg safety collection detection. After the staff performs the operation of rolling multiple eggs, the breakage rate of the collected eggs on the storage basket 31 is observed, and the detection data is obtained in combination with the material, multi-point pressure and tilt angle of the bottom net 6. When the breakage rate of the collected eggs is too high, it means that the bottom net 6 does not meet the requirements at this time. When the breakage rate of the eggs is within a reasonable range, it means that the bottom net 6 meets the requirements at this time. A comprehensive comparison is performed through multiple groups of data that meet the requirements to obtain more suitable bottom net 6 setting data.

[0064] It should be noted that when adjusting the inclination angle of the bottom net 6, the fixed plate 332 drives the lower hopper 345 to move synchronously, and cooperates with the up and down sliding of the first sliding block 342 on the vertical section of the door-shaped support frame 341 and the front and rear sliding of the connecting auxiliary rod 344 on the connecting block 343, which can ensure that the lower hopper 345 can move synchronously with the adjustment of the inclination angle of the bottom net 6 smoothly. At the same time, cooperate with the friction between the first sliding block 342 and the door-shaped support frame 341 and the friction between the connecting auxiliary rod 344 and the pushing member 43. When the lower hopper 345 is not subjected to force, the first sliding block 342 and the connecting auxiliary rod 344 remain stationary, so that the lower hopper 345 is more stable in the process of moving with the fixed plate 332. At the same time, the synchronous movement of the lower hopper 345 can ensure that the falling height of eggs above the bottom net 6 at different inclination angles is consistent, thereby improving the accuracy of the detection results.

[0065] Working principle: When in use, first place the bottom net 6 on the clamping member 33, and fix the bottom net 6 by the clamping member 33. According to the detection needs, multiple bottom nets 6 of the same material or multiple bottom nets 6 of different materials can be selected and fixed at different detection positions respectively. Then, the inclination angles of the multiple bottom nets 6 are adjusted by the second adjusting mechanism 5. According to the detection needs, the inclination angles of the multiple bottom nets 6 can be adjusted to be consistent or inconsistent. In the process of adjusting the inclination angle of the bottom net 6, the position of the magnetic strip 322 on the carrier plate 321 is adjusted by the adjusting member 41 to adjust the multiple carrier plates 321 to be linked or independent. When the multiple carrier plates 321 are linked, the second adjusting mechanism 5 is driven by the transmission member 42 to adjust the inclination angle of the bottom nets 6 on the multiple carrier plates 321. When the multiple carrier plates 321 are independent , the inclination angle of the bottom net 6 on each carrying plate 321 is adjusted separately through the corresponding second adjustment mechanism 5. After the placement and inclination angle adjustment of the bottom net 6 are completed, the staff transports the eggs to the bottom net 6 through the feeding piece 34, and the eggs roll down the bottom net 6 to the support piece 32. After the staff performs the operation of rolling down multiple eggs, the breakage rate of the eggs collected on the storage basket 31 is observed, and the detection data of the safe collection of the eggs on the bottom net 6 is obtained in combination with the material, multi-point pressure and inclination angle of the bottom net 6. When the breakage rate of the collected eggs is too high, it means that the setting data of the bottom net 6 does not meet the requirements at this time. When the breakage rate of the eggs is within a reasonable range, it means that the setting data of the bottom net 6 meets the requirements at this time, and a more suitable setting data of the bottom net 6 can be obtained by comprehensive comparison of multiple groups of data that meet the requirements.
