The pallet that has finished distributing the materials enters the pre-cooling chamber 18 through the second conveyor 12. The second conveyor 12 continuously conveys the pallet to the stacking machine 2. The stacking machine 2 operates to stack the pallets. After stacking to a certain height, the pallet conveyor 10 operates to transport the pallets to the hanger power mechanism 6. After the materials in the pallet are frozen in the freezing chamber 4, they are moved by the hanger power mechanism 6 to another pallet conveyor 10.

[0021] The tray transplanter 5 includes a motor 501, a first sprocket 502, a first transmission chain 503, a cam 504, a second sprocket 505, a slide bar 510, a slide bar connector 511, a support leg 512, a connecting block 513, a connecting plate 514, a support plate 515 and a fixed shaft 516. The connecting plate 514 is a rectangular structure. The left and right sides of the connecting plate 514 are symmetrically provided with support legs 512, and the inner sides of the support legs 512 are respectively provided with connecting blocks 513. The front and rear sides of the connecting plate 514 are respectively provided with support plates 515. The left and right ends of the bottom of the support plate 515 are respectively provided with support plates 516. A sliding rod connector 511 is fixedly installed, and a sliding rod 510 is respectively arranged at the bottom of the sliding rod connector 511. The sliding rod 510 is respectively slidably connected to the sliding holes opened on the connecting block 513. The cam 504 and the second sprocket 505 are respectively fixedly installed on the fixed shaft 516 arranged between the support plates 515. The motor 501 is fixedly installed on the inner bottom of one of the support plates 515. The first sprocket 502 is fixedly installed on the output shaft end of the motor 501. The first sprocket 502 is a double-layer sprocket. The first sprocket 502 is transmission-connected to the second sprocket 505 through the first transmission chain 503. By running the motor 501, the first sprocket 502 drives the second sprocket 505 to rotate through the first transmission chain 503, and the fixed shaft 516 between the support plates 515 is driven by the second sprocket 505, so that the cam 504 on the fixed shaft 516 rotates. The cam 504 is eccentrically installed on the fixed shaft 516. When the cam 504 rotates, due to the small distance between the cam 504 and the connecting plate 514, the cam 504 lifts the supporting plate 515 as a whole, so that the sliding rod 510 slides up and down along the sliding hole on the connecting block 513, and moves upward through the supporting plate 515, so that the pallet on the second transmission chain 508 is lifted up, and when the supporting plate 515 moves downward, the second transmission chain 508 transports the pallet to another pallet conveying device.

[0022] The tray transplanter 5 also includes a third sprocket 506, a fourth sprocket 507, a second transmission chain 508 and a transmission shaft 509. Two transmission shafts 509 are provided. The transmission shafts 509 are symmetrically arranged at the left and right ends of the inner top of the support plate 515, and the third sprocket 506 is fixedly installed on the transmission shaft 509. The fourth sprocket 507 is arranged in the inner middle part of one of the support plates 515, and the fourth sprocket 507 is rotatably connected to the support plate 515 through a pin shaft. The third sprocket 506 and the fourth sprocket 507 are transmission-connected to the first sprocket 502 through the second transmission chain 508. The first sprocket 502 is a double-layer sprocket. When the first sprocket 502 rotates, the third sprocket 506 and the fourth sprocket 507 are driven to rotate through the second transmission chain 508, so that the second transmission chain 508 transports the pallet to another pallet conveying device. Through the setting of the fourth sprocket 507, the second transmission chain 508 is tightened, so that the second transmission chain 508 can be transmitted smoothly.

[0023] The hanger power mechanism 6 includes a sling transmission machine 61, a pallet hanger 62, an S-shaped steel core track 63 and a pallet rack 64. Two sling transmission machines 61 are respectively provided. The sling transmission machines 61 are respectively arranged at the other end of the pallet conveyor 10. The S-shaped steel core track 63 is arranged on the inner top of the freezer compartment 4. The pallet hangers 62 are respectively arranged at the three turning points of the S-shaped steel core track 63. The left and right ends of the sling arranged at the bottom of the S-shaped steel core track 63 are respectively connected to the sling transmission machine 61 for transmission. The pallet racks 64 are respectively arranged in an equidistant array on the slings at the bottom of the S-shaped steel core track 63. The sling transmission machine 61 is operated to move the sling at the bottom of the S-shaped steel core track 63. The movement of the sling at the bottom of the S-shaped steel core track 63 drives the pallet rack 64 on the sling to move in an S shape inside the freezer 4, thereby fully freezing the pallet on the pallet rack 64 and the materials in the pallet. The arrangement of the pallet hanger 62 can stably support the sling at the bottom of the S-shaped steel core track 63, so that the pallet rack 64 on the sling can move smoothly.

[0024] It also includes a spray unit 9, which includes a spray chamber 91, a spray pipe 92 and a spray head 93. The spray chamber 91 is arranged at the discharge end on the left side of the top of the first pallet elevator 7. The spray pipe 92 is arranged at the top of the inner side of the spray chamber 91, and the spray heads 93 are arranged in an array at equal distances at the bottom of the spray pipe 92. When the first pallet elevator 7 transports the pallet into the spray chamber 91, the transmission device at the bottom of the spray chamber 91 transports the pallet at a uniform speed, and the spray head 93 at the bottom of the spray pipe 92 sprays the pallet evenly, so that the material on the pallet is initially thawed.

[0025] It also includes a first turnover machine 13, a thawing device 14, a second turnover machine 15 and a transmission frame 20. The transmission frame 20 is arranged at the left bottom of the spray chamber 91. The thawing device 14 is arranged directly below the transmission frame 20. The first turnover machine 13 is arranged directly above the thawing device 14. The second turnover machine 15 is arranged at the left end of the first turnover machine 13, and the second turnover machine 15 is located on the right side of the top feeding end of the second pallet elevator 8. The first turnover machine 13 and the second turnover machine 15 are respectively connected to the transmission frame 20 in terms of transmission. Through the setting of the transmission frame 20, the spray chamber 91 is transported out to the pallet and moved to the first turning machine 13. Through the operation of the first turning machine 13, the initially thawed material on the pallet is poured into the thawing equipment 14, and then the pallet is moved along the transmission frame 20 to the second turning machine 15. Through the operation of the second turning machine 15, the pallet is reversed again, and the pallet facing up is moved to the top of the second pallet elevator 8, and then the empty pallet is moved to the fourth conveyor 17 through the second pallet elevator 8, so that the pallet is automatically recycled. Through the setting of the thawing equipment 14, the material can be fully thawed.

[0026] The fourth conveyor 17 also includes a delaying platform 19, which is arranged at the bottom of the second pallet elevator 8 and is located at the right end of the fourth conveyor 17. When the bottom of the second pallet elevator 8 cannot deliver the pallet in time, the delaying platform 19 is arranged so that the pallet delivered downward by the second pallet elevator 8 can be delivered to the delaying platform 19, and the delivered pallet is diverted, thereby preventing the accumulation of materials at the bottom of the second pallet elevator 8.

[0027] The first conveyor 11, the second conveyor 12, the third conveyor 16 and the fourth conveyor 17 are all roller conveyors. Since the first conveyor, the second conveyor, the third conveyor and the fourth conveyor are all roller conveyors, the pallets can be smoothly transported. At the same time, the roller conveyor has a high cost performance, is durable, and saves maintenance and laying costs.

[0028] The working principle of the present invention is as follows: first, the material distributor 1 is operated to make the external materials fall evenly on the pallet, and the pallet that has completed the material distribution enters the pre-cooling chamber 18 through the second conveyor 12, and the second conveyor 12 continuously transports the pallet to the stacking machine 2, and the pallet is stacked by the stacking machine 2. After being stacked to a certain height, the pallet conveyor 10 is operated to transport it to the hanger power mechanism 6, and the sling transmission machine 61 is operated to move the sling at the bottom of the S-shaped steel core track 63, and the sling at the bottom of the S-shaped steel core track 63 is moved, thereby driving the pallet rack 64 on the sling to move in an S shape inside the freezing chamber 4, and then the pallet on the pallet rack 64 and the materials in the pallet are fully frozen, and the pallet hanger 62 is used. The arrangement can stably support the sling at the bottom of the S-shaped steel core track 63, so that the pallet rack 64 on the sling can move smoothly. After the materials in the pallet are frozen in the freezing chamber 4, they are moved to another pallet conveyor 10 by the hanger power mechanism 6. The pallet conveyor 10 then transports the pallet to the pallet dismantling machine 3. The pallet dismantling machine 3 dismantles the pallets one by one and transports them to the pallet transplanter 5. The motor 501 is operated to make the first sprocket 502 drive the second sprocket 505 to rotate through the first transmission chain 503, and the second sprocket 505 drives the fixed shaft 516 between the support plates 515 to rotate the cam 504 on the fixed shaft 516. The cam 504 is eccentrically installed on the fixed shaft 516. During the rotation, since the distance between the cam 504 and the connecting plate 514 is small, the cam 504 lifts the supporting plate 515 as a whole, so that the sliding rod 510 slides up and down along the sliding hole on the connecting block 513, and moves upward through the supporting plate 515, so that the pallet on the second transmission chain 508 is lifted up. When the supporting plate 515 moves downward, the first sprocket wheel 502 drives the third sprocket wheel 506 and the fourth sprocket wheel 507 to rotate through the second transmission chain 508, so that the second transmission chain 508 transfers the pallet to another pallet conveying device. Through the setting of the fourth sprocket wheel 507, the second transmission chain 508 is tightened, so that the second transmission chain 508 can be smoothly transmitted. When the pallet is conveyed to the third transmission chain 508, the pallet is moved to the third transmission chain 508. The pallet is then transported to the first pallet elevator 7 by the pallet transplanter 5 on the fourth conveyor 17. The first pallet elevator 7 is operated to transport the pallet to the spray chamber 91. The transmission device at the bottom of the spray chamber 91 transports the pallet at a uniform speed. The nozzle 93 at the bottom of the spray pipe 92 is used to evenly spray the pallet, so that the material on the pallet is preliminarily thawed. The transmission frame 20 is used to transport the pallet out of the spray chamber 91 to the first tray turning machine 13. The first tray turning machine 13 is used to pour the preliminarily thawed material on the pallet into the thawing device 14. The pallet is then moved along the transmission frame 20 to the second tray turning machine 15. The second tray turning machine 15 is used to reverse the pallet again.The pallet facing up is moved to the top of the second pallet elevator 8, and then the empty pallet is moved to the fourth conveyor 17 by the second pallet elevator 8. When the bottom of the second pallet elevator 8 cannot deliver the pallet in time, the delay table 19 is set so that the pallet delivered downward by the second pallet elevator 8 can be delivered to the delay table 19, and the delivered pallets are diverted to prevent the accumulation of materials at the bottom of the second pallet elevator 8. The empty pallet is delivered to the pallet transplanter 5 on the first conveyor 11 by the fourth conveyor 17, and then the empty pallet is delivered to the first conveyor 11 by the pallet transplanter 5, and then the empty pallet is delivered to the material distributor 1 by the first conveyor 11, so that the pallet can be recycled.
