A plurality of concave ball grooves 206 are arranged at intervals on the synchronous belt 205, and the concave ball grooves 206 on two adjacent synchronous belts 205 are aligned; several support plate assemblies 3. The support plate assemblies 3 include a support plate 301, a storage groove 302, and a support rod 303. Storage grooves 302 are arranged on both the top and bottom of the support plate 301. A plurality of support rods 303 are also arranged on the support plate 301. The diameter of the support rod 303 is matched with the aperture of the concave ball groove 206; a material taking mechanism 4. The material taking mechanism 4 includes a material taking plate 401, a guide rod 402, and a base 403. The material taking plate 401 is limited and slidably assembled in the box body 101 along the first direction x. The base 403 is fixedly assembled in the box body 101. One end of the guide rod 402 is fixedly connected to the base 403, and the other end of the guide rod 402 is elastically inserted into the material taking plate 401.

[0034] In actual application of this embodiment, one end of the box body 101 is provided with a feeding port 102 and a storage port 103, the feeding port 102 is used to take the livestock food after preservation in the cavity of the box body 101, and the storage port 103 is used to store the livestock food in the cavity of the box body 101, and the feeding port 102 and the storage port 103 are provided with independent feeding door panels 104 and storage door panels 105 on one side, and the cavity of the box body 101 is divided into a feeding position, a storage position and a flap position, and the feeding position is set on one side of the bottom of the cavity of the box body 101 and is close to the feeding port 102. The storage position is arranged in the middle of the cavity of the box body 101, the flap position is arranged on one side of the cavity top of the box body 101, and a plurality of flow channel components 2 are also arranged in the cavity of the box body 101, and the plurality of flow channel components 2 are arranged at the four corners of the inner cavity of the box body 101, and the two main flow channel wheels 201 and the secondary flow channel wheel 202 in the flow channel component 2 are arranged at the material taking position and the flap position, and the main flow channel wheel 201 and the secondary flow channel wheel 202 are both sleeved with a synchronous belt 205, and a plurality of concave ball grooves 206 are arranged at intervals on the synchronous belt 205, so that The main channel wheel 201 and the secondary channel wheel 202 are connected to each other through the main channel gear 203 and the secondary channel gear 204, so that when the main channel wheel 201 and the secondary channel wheel 202 rotate, the concave ball grooves 206 on the two sets of synchronous belts 205 are close to each other, and the support rod 303 on one side of the support plate 301 can be clamped, and a single support rod 303 can be clamped by a plurality of channel components 2 at the same time, so that a plurality of support plates 301 can move in sequence along the negative direction of the third direction z, thereby causing the stored livestock food to move from the storage position to the material taking position, and the livestock food can be moved to the material taking position. When the livestock food is at the storage position, the synchronous belt 205 can be pressed by the deadweight of the livestock food to move, so that the pallet 301 entering the material taking position can move to the flip position for mechanical reset after unloading, thereby realizing the cyclic movement of several pallets 301 in the material taking position, the storage position and the flip position, so that when there is livestock food stored in the fresh-keeping box, the material taking position always has livestock food to be taken, which is convenient for continuous taking of food from the same position. At the same time, there is no need to fully open the fresh-keeping box each time food is taken, which effectively reduces the loss of fresh-keeping cold air and reduces power loss.

[0035] The fresh-keeping method comprises:

[0036] S1: Open the material taking door plate 104 and the material storage door plate 105 at the same time. When the material taking door plate 104 is in the open state, the plurality of flow channel components 2 are in the locked state, and the livestock food to be preserved is placed on the plurality of support plates 301;

[0037] S2: Closing the material discharging door plate 104 and the material storing door plate 105 at the same time, when the material discharging door plate 104 is in the closed state, the plurality of flow channel components 2 are in a semi-unlocked state;

[0038] S3: If the pallet 301 at the material taking position is in the state of an empty tray, a plurality of runner components 2 are further switched to the fully unlocked state, so that the livestock food on a plurality of pallets 301 presses the synchronous belt 205 to move in the negative direction of the third direction z under the action of gravity, thereby driving the empty tray at the material taking position to move to the turning plate position for mechanical resetting;

[0039] S4: If the pallet 301 at the material taking position is in the state of carrying materials, a plurality of runner components 2 are still in the semi-unlocked state. At this time, after opening the material taking door panel 104 to empty the livestock food at the material taking position, the runner components 2 are further switched to the fully unlocked state, thereby driving the empty tray to move to the turning plate position for mechanical resetting;

[0040] S5: Repeat the above steps.

[0041] In one case of this embodiment, the fresh-keeping box is defaultly subjected to fresh-keeping treatment by a refrigerator, and the specific structure of the refrigerator is not limited herein.

[0042] Please refer to Figure 4 , in a preferred embodiment of the present invention, the box body assembly 1 further includes an L-shaped bracket 106 and a push rod 107. The L-shaped bracket 106 is fixedly arranged on one side of the material taking door panel 104. The push rod 107 is rotationally assembled on the L-shaped bracket 106 in a limited manner. The material taking plate 401 has opposite first contact surfaces a1 and second contact surfaces a2, and the push rod 107 is movably abutted on the first contact surface a1 and the second contact surface a2.

[0043] In the actual application of this embodiment, the L-shaped bracket 106 is fixedly arranged on the material taking door panel 104, and the push rod 107 is elastically rotationally assembled on one side of the L-shaped bracket 106. The L-shaped bracket 106 defines the rotation direction of the push rod 107 in the xoy plane. When the material taking position is in the open state, during the closing process of the material taking door panel 104, the push rod 107 is movably abutted on the first contact surface a1, so that the material taking plate 401 moves in the negative direction of the first direction x, thereby causing the material taking plate 401 to drive the pallet 301 thereon to move toward the suspension assembly 5. When the pallet 301 at the material taking position is in the state of an empty tray, the pallet 301 is clamped into the suspension assembly 5 and moves to the turning plate position for mechanical resetting. When the pallet 301 at the material taking position is in the state of carrying materials, when the push rod 107 slides to the edge position of the first contact surface a1, it immediately slides off from one side of the material taking plate 401, so that the material taking plate 401 automatically resets under the elastic force, thereby driving the pallet 301 thereon to reset simultaneously.

[0044] In a case of this embodiment, during the opening process of the material taking door panel 104, since the push rod 107 is elastically rotatably assembled on the L-shaped bracket 106, the push rod 107 always slides and abuts against the second contact surface a2 until the material taking door panel 104 is completely opened. Then, the push rod 107 slides away from one side of the second contact surface a2 and elastically resets to one end of the L-shaped bracket 106.

[0045] Please refer to Figure 2 and Figure 6 In a preferred embodiment of the present invention, the material taking mechanism 4 further includes a pressure rod 404, a pin 405 and a pull handle 406. One end of the material taking plate 401 is also slidably inserted with a pressure rod 404. The pressure rod 404 is arranged towards the base 403 side. The top of the material taking plate 401 is also movably assembled with a pin 405, and the pin 405 and the pressure rod 404 are linked.

[0046] In the actual application of this embodiment, when the pallet 301 at the material taking position is in the empty tray state, during the process of the pressure rod 404 moving towards the base 403, the pressure rod 404 drives the pin 405 to contract when abutting against the base 403, so that the pallet 301 assembled on the material taking plate 401 can slide and be clamped into the suspension assembly 5 and move to the flap position following the vertical bracket 501. When the material taking plate 401 is pulled along the positive direction of the first direction x by the pull handle 406, the pin 405 can limit the sliding of the pallet 301 on the surface of the material taking plate 401, preventing the pallet 301 from slipping off the material taking plate 401 during the material taking process.

[0047] Please refer to Figure 8 In a preferred embodiment of this embodiment, the livestock food preservation box further includes two groups of suspension assemblies 5. The suspension assembly 5 includes a vertical bracket 501, a vertical guide wheel 502, a suspension belt 503 and an inclined stretching tooth 504. The vertical bracket 501 is fixedly assembled in the box body 101. The vertical guide wheels 502 are rotatably arranged at both ends of the vertical bracket 501. A suspension belt 503 is sleeved on the two groups of vertical guide wheels 502, and a plurality of inclined stretching teeth 504 are arranged in an array on the suspension belt 503.

[0048] In the actual application of this embodiment, the two groups of vertical brackets 501 are fixedly arranged in the box body 101. The vertical guide wheels 502 can drive the suspension belt 503 to rotate synchronously during the rotation process. Since a plurality of inclined stretching teeth 504 are arranged on the suspension belt 503, when the empty pallet 301 follows the material taking plate 401 and moves along the positive direction of the first direction x, the support rods 303 on both sides of the pallet 301 slide and are clamped into the inclined stretching teeth 504. When the inclined stretching teeth 504 move along the positive direction of the third direction z, the pallet 301 can be pulled to rotate counterclockwise and be suspended on the inclined stretching teeth 504, and continue to move along the positive direction of the third direction z following the inclined stretching teeth 504.

[0049] In one case of this embodiment, the suspension assembly 5 further includes a guiding groove 505, a guiding groove inlet 506, a guiding groove outlet 507, a horizontal support plate 508, and an inclined pushing block 509. The guiding groove 505 is arranged on one side of the top of the cavity of the box body 101. One end of the guiding groove 505 is provided with the guiding groove inlet 506, which is arranged close to the suspension belt 503. The other end of the guiding groove 505 is provided with the guiding groove outlet 507. The horizontal support plate 508 is fixedly arranged in the box body 101 and is disposed between two adjacent flow channel assemblies 2. The inclined pushing block 509 is fixedly arranged in the box body 101 and is disposed between two suspension belts 503. When the support plate 301 moves from the material taking position to the turning plate position, when the support plate 301 abuts against one end of the inclined pushing block 509, the support rod 303 on the front end side of the support plate 301 slips off the inclined stretching tooth 504 and enters the guiding groove inlet 506. At this time, under the continuous pushing of the inclined stretching tooth 504 on the support rod 303 on the rear end side of the support plate 301, the support rod 303 on the front end side of the support plate 301 slides along the cavity wall of the guiding groove 505 until the support rod 303 on the front end side of the support plate 301 slides to the guiding groove outlet 507. During the process that the rear end of the support plate 301 abuts against the inclined pushing block 509, the support rod 303 on the rear end side is separated from the inclined stretching tooth 504, so that the turned support plate 301 drops onto the horizontal support plate 508 after turning over. Moreover, when the support rods 303 at the front end and the rear end of the support plate 301 contact a plurality of main flow channel wheels 201 and auxiliary flow channel wheels 202, the support rods 303 at the front end and the rear end of the support plate 301 can be respectively clamped into the concave spherical grooves 206 in a plurality of flow channel assemblies 2, so that the support plate 301 in the turning plate position is mechanically reset.

[0050] Please refer to Figure 7 , in a preferred embodiment of the present invention, the suspension assembly 5 further includes a first transmission wheel 510, a first transmission gear 511, a second transmission gear 512, a second transmission wheel 513, and a third transmission wheel 514. The first transmission wheel 510 is fixedly arranged on the axis in the box body 101 and is in transmission connection with any one group of main flow channel wheels 201. One end of the first transmission wheel 510 is fixedly assembled with the first transmission gear 511 on the axis. The second transmission gear 512 is fixedly arranged on the axis in the box body 101, and one end of the second transmission gear 512 is in transmission connection with the first transmission gear 511. The other end of the second transmission gear 512 is coaxially assembled with the second transmission wheel 513. One end of the third transmission wheel 514 is in transmission connection with the second transmission wheel 513, and the other end of the third transmission wheel 514 is in transmission connection with any one group of vertical guide wheels 502.

[0051] In actual application of this embodiment, during the rotation of the main runner wheel 201, the first transmission wheel 510 can be synchronously driven to rotate. The first transmission wheel 510 is transmitted to one side of the second transmission wheel 513 through the first transmission gear 511 and the second transmission gear 512. The transmission ratio between the second transmission wheel 513 and the third transmission wheel 514 is less than 1, so that the third transmission wheel 514 rotates at an increased speed. Then, the third transmission wheel 514 drives the suspension belt 503 to rotate at an increased speed. When the livestock food on several pallets 301 presses the pallet 301 to move in the negative direction of the third direction z under the action of gravity, the main runner wheel 201 rotates synchronously, so that the vertical guide wheel 502 drives the suspension belt 503 to rotate at an increased speed during the transmission process, and then the empty tray at the material taking position is pulled to the turning plate position.

[0052] Please refer to Figure 4 and Figure 11 , in a preferred embodiment of the present invention, the livestock food fresh-keeping box further includes a locking assembly 6. The locking assembly 6 includes a trigger shaft 601, a transmission shaft 602, a cam 603, a locking disc 604, a locking bracket 605 and a locking head 606.

One end of the locking bracket 605 is in movable contact with the cam 603, and the other end of the locking bracket 605 is fixedly provided with 66. The locking head 606 is in movable connection with the locking disc 604.

[0053] In actual application of this embodiment, when the material taking door panel 104 is in the open state, the trigger shaft 601 and the transmission shaft 602 drive the cam 603 thereon to rotate during the rotation process, so that the protrusion on the cam 603 is in movable contact with the locking bracket 605, and then the locking bracket 605 is pushed towards the locking disc 604, so that the locking head 606 is movably pressed into the locking disc 604, thereby stopping the rotation of the main runner wheel 201 on one side of the locking disc 604. When the material taking door panel 104 is in the closed state, the groove on the cam 603 rotates to one side of the locking bracket 605, so that the locking bracket 605 slides into the groove under the elastic force. At this time, the locking head 606 can slide out from one side of the locking disc 604.

[0054] In one case of this embodiment, the several main runner wheels 201 are all connected in transmission through a linkage belt 207, so that after one group of main runner wheels 201 stops rotating, the several main runner wheels 201 and the sub-runner wheels 202 stop rotating simultaneously.

[0055] Further, the locking assembly 6 further includes an inclined pressure groove 607, a pressure support plate 608 and a linkage arm 609. The inclined pressure groove 607 is fixedly arranged at the bottom of the locking frame 605. The pressure support plate 608 is elastically assembled to the bottom of the cavity of the box body 101 along the third direction z. One end of the linkage arm 609 is in movable abutment with the inclined pressure groove 607, and the other end of the linkage arm 609 is fixedly connected to the pressure support plate 608. When the pallet 301 at the material taking position carries food, the pallet 301 can press the pressure support plate 608 to move in the negative direction of the third direction z, so that the pressure support plate 608 drives the linkage arm 609 to move synchronously in the negative direction of the third direction z, and then the linkage arm 609 slides and pushes the inclined pressure groove 607 to move, so that the inclined pressure groove 607 drives the locking frame 605 to approach the locking disc 604, and further the main runner wheel 201 and the auxiliary runner wheel 202 are switched to the locking state. When the main runner wheel 201 and the auxiliary runner wheel 202 are in the locking state, the vertical guide wheel 502 is simultaneously in a stopped state. At this time, when the support rod 303 at the front end of the pallet 301 slides into the inclined stretching tooth 504, it does not move along the positive direction of the third direction z following the inclined stretching tooth 504. Therefore, when the material taking plate 401 elastically resets in the positive direction of the first direction x, the pallet 301 on this side synchronously follows the material taking plate 401 to reset to the material taking position.

[0056] In the above embodiments of the present invention, a livestock food fresh-keeping box and a fresh-keeping method are provided. By arranging an independent material taking position, a storage position and a flap position inside the box body 101, and configuring a plurality of pallets 301 that move cyclically therebetween, food can be continuously taken from the same position, and each time food is taken, the fresh-keeping box does not need to be completely opened, which can effectively reduce the loss of fresh-keeping cold air and reduce power consumption.

[0057] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
