[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example: Figure 1-3 As shown, the utility model provides a technical solution: a vacuum freeze dryer, comprising a workbench 1 and a dryer body 2, a U-shaped plate 11 is fixedly installed on the bottom surface of the workbench 1, a cylinder 12 is arranged on the inner side of the U-shaped plate 11, a movable groove 13 is opened on the top of the workbench 1, a driving end of the cylinder 12 passes through the movable groove 13 and is fixedly connected with a first connecting column 15, a symmetrically distributed first clamping plate 14 is fixedly installed on one side of the bottom surface of the dryer body 2, both ends of the first connecting column 15 are rotatably clamped on the inner side of the first clamping plate 14, a symmetrically distributed second clamping plate 16 is fixedly installed on the bottom surface of the U-shaped plate 11, a second connecting column 17 is rotatably clamped on the opposite end of the second clamping plate 16, a connecting block 18 is fixedly connected to the outer side of the second connecting column 17, the top of the connecting block 18 is fixedly connected to the bottom surface of the cylinder 12, and a controller body 19 is fixedly installed on the front side of the dryer body 2.

[0019] A symmetrically distributed third clamping plate 20 is fixedly installed on one side of the top of the workbench 1, and a support shaft 21 is fixedly clamped on the opposite end of the third clamping plate 20. A rotating drum 22 is rotatably sleeved on the outer side of the support shaft 21, and a connecting plate 23 is fixedly connected to the outer side of the rotating drum 22. The top of the connecting plate 23 is fixedly connected to the dryer body 2.

[0020] By adopting the above technical solution, the drum 22 rotates on the support shaft 21 so that when the dryer body 2 rotates, the connecting plate 23 is connected to the drum 22, thereby limiting the rotation of the dryer body 2 and supporting a part of the gravity of the dryer body 2 itself.

[0021] A symmetrically distributed support block 24 is fixedly installed on one side of the top of the dryer body 2, and the opposite end of the support block 24 is rotatably connected to a rotating shaft 25, one end of the rotating shaft 25 is fixedly connected to a fixed block 26, and one end of the fixed block 26 is fixedly connected to a magnetic plate 27, and the bottom surface of the magnetic plate 27 is in contact with the dryer body 2.

[0022] By adopting the above technical solution, the magnetic plate 27 can be rotated by rotating the rotating shaft 25 on the supporting block 24 to cooperate with the fixed block 26 so that the magnetic plate 27 can seal the dryer body 2. The magnetic plate 27 is attracted to the dryer body 2 by magnetic force to prevent the magnetic plate 27 from being thrown away by the movement of the cylinder 12 and leaking the material.

[0023] A pull cover 28 is fixedly connected to one side of the top end of the magnetic plate 27 .

[0024] By adopting the above technical solution, by providing the pull cover 28, it is convenient to pull the pull cover 28 to open the magnetic plate 27 and then put the materials to be dried.

[0025] An array of fixed plates 29 is fixedly installed on the lower outer side of the workbench 1 , and a roller 30 is fixedly connected to the bottom surface of the fixed plate 29 .

[0026] By adopting the above technical solution, the roller 30 is provided so as to drive the workbench 1 to move.

[0027] A C-shaped plate 31 is fixedly mounted on the side end of the workbench 1 , and a handle 32 is fixedly inserted into the inner side of the C-shaped plate 31 .

[0028] By adopting the above technical solution, the handle 32 is provided to facilitate the control of the movement of the roller 30, thereby facilitating the control of the movement direction of the workbench 1.

[0029] Working principle: First, pull the cover 28 with force to rotate the magnetic plate 27 to open, and the fixed block 26 rotates on the support block 24 in cooperation with the fixed block 26. Then put the material to be dried into the dryer body 2, and then close the magnetic plate 27. Use the controller body 19 to start the dryer body 2 for drying. Then drive the cylinder 12 to reciprocate and push the driving end. The first connecting column 15 connected to the driving end moves and rotates on the first clamping plate 14, so that the dryer body 2 is constantly swinging. At the same time, the rotating drum 22 drives the connecting plate 23 to rotate on the support shaft 21 with the dryer body 2 to limit the dryer body 2. The cylinder 12 will also rotate in cooperation with the driving end, and the second connecting column 17 rotates the connecting block 18 on the second clamping plate 16 to cooperate with the movement of the cylinder 12, thereby realizing the reciprocating swing of the dryer body 2 to make the internal material shake, preventing the material from sticking together and being dried, thereby improving the yield rate of material drying and improving the quality.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
