[0032] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: it includes a frost storage box 1, two groups of supporting vertical plates 2 are fixedly connected to the frost storage box 1, a movable plate 17 is slidably installed between the two groups of supporting vertical plates 2, a mounting plate 25 is fixedly connected to one side of the movable plate 17, a scraper 8 is fixedly connected to one side of the mounting plate 25, a defrost table 3 is fixedly installed on the two groups of supporting vertical plates 2, four groups of slide grooves 11 are opened inside the defrost table 3, sliders 12 are slidably installed in the four groups of slide grooves 11, a defrost roller 7 is arranged between two groups of relative sliders 12, a reciprocating screw 16 is rotatably installed on the frost storage box 1, the reciprocating screw 16 is threadedly connected to the movable plate 17, and a connecting rod 23 is movably installed between the slider 12 and the movable plate 17.

[0033] The reciprocating screw 16 rotates to push the movable plate 17 to move up and down, and the movable plate 17 drives the mounting plate 25 to move up and down, and the mounting plate 25 drives the scraper 8 to move up and down, and the scraper 8 moves up and down to remove the frost on the side wall of the cold storage. At the same time, the movable plate 17 drives the connecting rod 23 to move up and down, and the connecting rod 23 drives the slider 12 to slide left and right in the slide groove 11, and the slide groove 11 drives the defrost roller 7 to slide left and right, and the defrost roller 7 removes the frost on the top of the cold storage, thereby realizing that the device can clean the frost around and on the top of the cold storage at the same time, thereby improving the frost cleaning efficiency of the cold storage.

[0034] It is further explained that a sealed box 20 is fixedly connected to the inside of the frost storage box 1 , a motor 21 is fixedly installed in the sealed box 20 , and a driving shaft of the motor 21 passes through the frost storage box 1 and is coaxially fixedly connected to the reciprocating screw rod 16 .

[0035] The motor 21 can drive the reciprocating screw 16 to rotate, and the motor 21 provides driving force for the reciprocating screw 16. The sealing box 20 protects the motor 21 to prevent the cleared frost from entering the motor 21 and causing damage to the motor 21, thereby improving the practicability of the device.

[0036] It is further explained that a rotating rod 18 is rotatably installed between the two groups of sliders 12, the defrost roller 7 is fixedly sleeved on the outside of the rotating rod 18, a rack 14 is fixedly installed on the defrost table 3, a gear 13 is meshed on the rack 14, and the gear 13 is fixedly sleeved on the outside of the rotating rod 18.

The gear 13 is meshed with the rack 14 and the rack 14 is fixedly installed, so the gear 13 will rotate while moving. The gear 13 drives the rotating rod 18 and the defrost roller 7 to rotate, so that the defrost roller 7 moves and rotates at the same time, thereby improving the defrosting efficiency of the defrost roller 7 and further improving the defrosting efficiency of the device.

[0038] It is further explained that a first hinge seat 22 is fixedly mounted on the movable plate 17, a connecting rod 23 is rotatably connected to the first hinge seat 22, one end of the connecting rod 23 away from the first hinge seat 22 is rotatably mounted in a second hinge seat 24, and the second hinge seat 24 is fixedly connected to the bottom of the slider 12.

[0039] When the movable plate 17 moves upward, the movable plate 17 drives the first hinge seat 22 to move upward, the first hinge seat 22 drives the connecting rod 23 to move upward, the connecting rod 23 pushes the slider 12 to slide in the slide groove 11, and the connecting rod 23 is movably connected between the movable plate 17 and the slider 12 through the first hinge seat 22 and the second hinge seat 24.

[0040] It is further explained that four groups of limit blocks 15 are fixedly connected to the movable plate 17 , and the four groups of limit blocks 15 are all slidably connected to the supporting vertical plates 2 .

[0041] The limit block 15 is vertically connected to the movable plate 17.

[0047] Specific reference is made to the following operations: the push-pull rod 5 cooperates with the universal wheel 4 to move the device to the defrosting position, and the motor 21 is started. The motor 21 drives the reciprocating screw 16 to rotate, and the reciprocating screw 16 rotates to push the movable plate 17 to move up and down, and the movable plate 17 drives the mounting plate 25 to move up and down, and the mounting plate 25 drives the scraper 8 to move up and down, and the scraper 8 moves up and down to remove the frost on the side wall of the cold storage.
