[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Example

[0044] Reference Figure 1-Figure 9 The present invention provides a technical solution: an energy-saving crop steam block single freezing machine, comprising a single freezing box 1, a feed inlet 11 and a discharge port 12 are arranged on the single freezing box 1, a cross bar 21 is connected to the feed inlet 11, a swing plate 2 is rotatably connected to the cross bar 21, an arc rod 22 is connected to the swing plate 2, a displacement sensor 23 for monitoring the movement stroke of the arc rod 22 is arranged in the single freezing box 1; a mounting frame 31 is vertically slidably connected in the single freezing box 1, a roller 32 is rotatably connected to the mounting frame 31, and a plurality of flaps 33 are connected to the side wall of the roller 32 in a ring array; when the displacement sensor 23 detects that the arc rod 22 moves, the mounting frame 31 moves downward, and the roller 32 rotates, so that the flap 33 moves the crops to increase the time that the crops stay in the single freezing box 1.

[0045] The cut crops are put into the single freezing box 1 from the feed port 11, and the frozen crops are discharged from the discharge port 12. When the crops enter the single freezing box 1, they push the swing plate 2 to swing. When the volume of the crops is large, the swing angle of the swing plate 2 is large. At this time, the moving distance of the arc rod 22 on the swing plate 2 increases. When the crops move to the bottom of the roller 32, according to the swing angle of the swing plate 2 pushed by the crops, the roller 32 moves down and rotates for a suitable time. The roller 32 has a built-in motor to drive the rotation of the roller 32. When the roller 32 moves down and rotates, the flap 33 on the roller 32 pushes the crops to move in the single freezing box 1 without changing the distance, thereby increasing the freezing time of the crops. The multiple flaps 33 alternately move the crop steam block, so that the crop steam block can be turned over, thereby improving the single freezing effect of the crop steam block, so that the large-volume crops can be frozen for a sufficient time, and the inside of the large-volume crops can also be frozen solid.

[0046] The single freezer also includes a protective cover 19. The single freezer 1, the refrigerator 6, and the electric control box 7 are all arranged in the protective cover 19. The front side of the protective cover 19 is provided with a feed conveyor 191 and a discharge conveyor 192 which are respectively connected to the feed port 11 and the discharge port 12. The feed conveyor 191 is used to feed materials to the feed end of the steel belt 15, and the discharge conveyor 192 is used to receive materials at the discharge end of the steel belt 15. The front side of the protective cover 19 is also provided with an operating window for operating the electric control box.

[0047] There are multiple swing plates 2 and mounting frames 31, and multiple swing plates 2 are linearly connected to the cross bar 21, and multiple mounting frames 31 are linearly connected to the single freezer 1; multiple first cylinders 3 corresponding to the multiple mounting frames 31 are connected to the single freezer 1, and the multiple mounting frames 31 are respectively connected to the output ends of the multiple first cylinders 3.

[0048] By providing a plurality of swing plates 2, a plurality of crop steam blocks placed on the single freezing box 1 can be frozen for a suitable time accordingly.

[0049] A plurality of positioning blocks 34 are connected to the top wall of the single freezer 1, a positioning column 35 is coaxially connected to the end of the roller 32, and a plurality of positioning grooves 36 corresponding to the plurality of flaps 33 are provided on the side wall of the positioning column 35; when the roller 32 moves upward, the positioning column 35 contacts the positioning block 34 so that the positioning block 34 moves into the positioning groove 36, thereby causing one of the flaps 33 on the side wall of the roller 32 to face vertically downward.

[0050] After the crop steam block is frozen for a suitable time, the first cylinder 3 contracts and drives the mounting frame 31 to move upward. At this time, the roller 32 drives the positioning column 35 to move upward synchronously, so that the positioning groove 36 provided on the side of the positioning column 35 can be engaged with the positioning block 34, so that one of the flaps 33 on the side wall of the roller 32 is vertically downward, so that when the roller 32 moves downward next time, the flap 33 can timely contact and block the crop steam block, ensuring that the large-volume crop steam block can be intercepted in time to increase the freezing time, so that the large-volume crop steam block can be frozen for a sufficient time.

[0051] A plurality of lower pressure frames 42 corresponding to the plurality of rollers 32 are vertically slidably connected in the single freezer 1, and a plurality of arc-shaped vertical plates 44 are connected to the lower parts of the plurality of lower pressure frames 42; when the rollers 32 move downward, the corresponding lower pressure frames 42 move downward synchronously so that the crops that have not reached under the rollers 32 do not move relative to the single freezer 1.

[0052] When the first cylinder 3 is extended, the second cylinder 4 is extended synchronously, and the lower pressing frame 42 moves downward, so that the crop steam blocks placed later are blocked by the arc vertical plate 44, thereby preventing multiple crop steam blocks from being blocked and piled up in the same place to affect the freezing effect.

[0053] The lower part of the lower pressure frame 42 is connected to multiple mounting seats 43, and multiple arc-shaped vertical plates 44 slide vertically in the multiple mounting seats 43 respectively; the upper part of the arc-shaped vertical plate 44 is connected to a guide rod 45, and a spring 46 is sleeved on the guide rod 45, and the two ends of the spring 46 are respectively connected to the mounting seat 43 and the arc-shaped vertical plate 44.

[0054] When the lower pressing frame 42 moves downward, the arc-shaped vertical plate 44 blocks the crop steaming block, and the arc-shaped vertical plate 44 is vertically slidably connected to the lower part of the lower pressing frame 42 through the spring 46, so that if the arc-shaped vertical plate 44 presses the crop steaming block when moving downward, the contraction of the spring 46 enables the arc-shaped vertical plate 44 to move upward to prevent the crop steaming block from being crushed.

[0055] A plurality of second cylinders 4 are connected to the single freezer 1, and output ends of the plurality of second cylinders 4 are fixedly connected with connection blocks 41, and the plurality of connection blocks 41 are fixedly connected with the plurality of lower pressure frames 42 in a one-to-one correspondence.

[0056] The contraction of the second cylinder 4 can control the up and down movement of the lower pressing frame 42 .

[0057] A first roller 13 and a second roller 14 are rotatably connected to the feed port 11 and the discharge port 12 of the single freezer 1, a steel belt 15 is connected between the first roller 13 and the second roller 14, a driving wheel 16 and a driven wheel 17 are connected to the ends of the first roller 13 and the second roller 14, and a belt 18 is connected between the driving wheel 16 and the driven wheel 17.

[0058] Either one of the first roller 13 and the second roller 14 is connected to a driving motor. When the driving motor is running, it drives the first roller 13 or the second roller 14 to rotate. At this time, the first roller 13 or the second roller 14 rotates synchronously through the belt 18, so that the steel belt 15 runs. At this time, the crop steam blocks placed on the steel belt 15 can be transported to the single freezer 1 through the steel belt 15 for freezing.

[0059] A knocking block 5 is arranged in the annular gap of the steel belt 15 in the single freezer 1, and a knocking frame 51 is connected to the knocking block 5, and a rotating rod 52 is connected to the knocking frame 51, and the rotating rod 52 is rotatably connected to the single freezer 1. A ring 53 is connected to the single freezer 1, and a torsion spring 54 is connected between the ring 53 and the rotating rod 52; a disc 55 is connected to the end of the second roller shaft 14, and a pressure rod 56 is connected to the end face of the disc 55. When the disc 55 rotates, the pressure rod 56 can move the knocking frame 51 to allow the torsion spring 54 to store energy.

[0060] When the second roller 14 rotates, the disc 55 rotates synchronously. At this time, the pressure rod 56 on the disc 55 repeatedly moves the knocking frame 51. At this time, the rotating rod 52 on the knocking frame 51 rotates, so that the torsion spring 54 between the rotating rod 52 and the ring 53 is energized. When the disc 55 continues to rotate to make the pressure rod 56 move away from the knocking frame 51, the energy stored in the torsion spring 54 is released, so that the knocking frame 51 swings to make the knocking block 5 knock the steel belt 15, so that the steel belt 15 vibrates, so that the frozen crop steamed block on the steel belt 15 is vibrated to separate from the steel belt 15.

[0061] It also includes a refrigerator 6 and an electric control box 7. The refrigerator 6 is provided with a frequency converter for cooling the single freezer 1. The electric control box 7 is used to control the entire electrical system of the single freezer.

[0062] The frequency converter provided in the refrigerator 6 reduces the electric energy consumed during its operation, thereby achieving an energy-saving effect.

[0063] A single quick freezing method, applied to an energy-saving crop steam block single freezing machine, comprises the following steps:

[0064] S1, transporting the crop steam blocks to be frozen into the single freezing box 1 through the steel belt 15;

[0065] S2, the steamed crop blocks enter the single freezing box 1 through the feed inlet 11 and push the swing plate 2 to swing toward the inside of the single freezing box 1;

[0066] S3, when the swing plate 2 swings, the arc rod 22 connected to the swing plate 2 moves with the hinge point of the swing plate 2 as the center of the circle, and the displacement sensor 23 captures the sliding stroke of the arc rod 22 to obtain the thickness of the crop steam block;

[0067] S4, after the displacement sensor 23 detects that the arc rod 22 moves, and the crop steam block that pushes the swing plate 2 to swing is about to move to the bottom of the first cylinder 3, the first cylinder 3 extends, so that the flap 33 on the roller 32 blocks the crop steam block;

[0068] S5, after the flap 33 blocks the steamed crop block, the roller 32 rotates to increase the time that the steamed crop block stays in the single freezer 1;

[0069] S6, while the first cylinder 3 is extended, the second cylinder 4 is extended synchronously, and the lower pressing frame 42 falls down to block the crop steam block between the feed port 11 and the roller 32;

[0070] S7, the first cylinder 3 is stretched and then shortened, and the second cylinder 4 is shortened synchronously. The extension time of the first cylinder 3 and the second cylinder 4 is adaptively adjusted according to the size of the crop steam block. After the first cylinder 3 is shortened, the roller 32 stops rotating.

[0071] Working principle: The energy-saving crop steam block single freezing machine and single quick freezing method are used to put the cut crops into the single freezing box 1 from the feed port 11, and the frozen crops are discharged from the discharge port 12. When the crops enter the single freezing box 1, they push the swing plate 2 to swing. When the volume of the crops is large, the swing angle of the swing plate 2 is large. At this time, the moving distance of the arc rod 22 on the swing plate 2 increases. When the crops move to the bottom of the roller 32, according to the swing angle of the crops pushing the swing plate 2, the roller 32 moves down and rotates. When the roller 32 moves at the appropriate time, the built-in motor of the roller 32 drives the rotation of the roller 32. When the roller 32 moves down and rotates, the flap 33 on the roller 32 pushes the crops to move in the single freezer 1 at a constant distance, thereby increasing the freezing time of the crops. In addition, the plurality of flaps 33 alternately move the crop steam block so that the crop steam block can be turned over, thereby improving the single freezing effect of the crop steam block, so that large crops can be frozen for a sufficient time, and the inside of the large crops can also be frozen solid.

[0072] By providing a plurality of swing plates 2, a plurality of crop steam blocks placed on the single freezing box 1 can be frozen for a suitable time accordingly.

[0073] After the crop steam block is frozen for a suitable time, the first cylinder 3 contracts and drives the mounting frame 31 to move upward. At this time, the roller 32 drives the positioning column 35 to move upward synchronously, so that the positioning groove 36 provided on the side of the positioning column 35 can be engaged with the positioning block 34, so that one of the flaps 33 on the side wall of the roller 32 is vertically downward, so that when the roller 32 moves downward next time, the flap 33 can timely contact and block the crop steam block, ensuring that the large-volume crop steam block can be intercepted in time to increase the freezing time, so that the large-volume crop steam block can be frozen for a sufficient time.

[0074] When the first cylinder 3 is extended, the second cylinder 4 is extended synchronously, and the lower pressing frame 42 moves downward, so that the crop steam blocks placed later are blocked by the arc vertical plate 44, thereby preventing multiple crop steam blocks from being blocked and piled up in the same place to affect the freezing effect.

[0075] When the lower pressing frame 42 moves downward, the arc-shaped vertical plate 44 blocks the crop steaming block, and the arc-shaped vertical plate 44 is vertically slidably connected to the lower part of the lower pressing frame 42 through the spring 46, so that if the arc-shaped vertical plate 44 presses the crop steaming block when moving downward, the contraction of the spring 46 enables the arc-shaped vertical plate 44 to move upward to prevent the crop steaming block from being crushed.

[0076] The contraction of the second cylinder 4 can control the up and down movement of the lower pressing frame 42 .

[0077] Either one of the first roller 13 and the second roller 14 is connected to a driving motor. When the driving motor is running, it drives the first roller 13 or the second roller 14 to rotate. At this time, the first roller 13 or the second roller 14 rotates synchronously through the belt 18, so that the steel belt 15 runs. At this time, the crop steam blocks placed on the steel belt 15 can be transported to the single freezer 1 through the steel belt 15 for freezing.

[0078] When the second roller 14 rotates, the disc 55 rotates synchronously. At this time, the pressure rod 56 on the disc 55 repeatedly moves the knocking frame 51. At this time, the rotating rod 52 on the knocking frame 51 rotates, so that the torsion spring 54 between the rotating rod 52 and the ring 53 is energized. When the disc 55 continues to rotate to make the pressure rod 56 move away from the knocking frame 51, the energy stored in the torsion spring 54 is released, so that the knocking frame 51 swings to make the knocking block 5 knock the steel belt 15, so that the steel belt 15 vibrates, so that the frozen crop steamed block on the steel belt 15 is vibrated to separate from the steel belt 15.

[0079] The frequency converter provided in the refrigerator 6 reduces the electric energy consumed during its operation, thereby achieving an energy-saving effect.
