The function of the slide rail 208 is to enable the linear motor 209 to move on it, thereby driving the limit plate 210 to move, and the main function of the limit plate 210 is to limit and fix the fruit and vegetable box.

[0026] Specifically, in the above specific embodiment, the first rotating motor 103 is fixedly connected to the center of the lower bottom plate 101, and the output end of the first rotating motor 103 is fixedly connected to the driving gear 104, and the lower end of the driving gear 104 is meshed with a driven gear 105, and a connecting shaft 107 is penetrated through the middle of the driven gear 105, and rollers 108 are arranged at both ends of the connecting shaft 107. The driving gear 104 can drive the driven gear 105 to rotate under the driving action of the first rotating motor 103, and when the driven gear 105 rotates, it can drive the connecting shaft 107 to rotate together, and when the connecting shaft 107 rotates, it can drive the rollers 108 at both ends to rotate together, so that the movement of the entire lifting platform can be realized.

[0027] Specifically, in the above specific embodiment, the lower end surface of the lower base plate 101 is fixedly connected with a protection box 106, and the driven gear 105 is rotatably supported inside the protection box 106 through a connecting shaft 107, and both ends of the connecting shaft 107 penetrate the protection box 106 and are exposed outside the protection box 106. The main function of the protection box 106 is to protect the driven gear 105 and prevent the driven gear 105 from being damaged during the movement of the lifting platform.

[0028] Specifically, in the above specific embodiment, two motor protection boxes 202 are fixedly connected to the rear side of the upper base plate 201, and the second rotating motor 203 is fixedly connected inside each motor protection box 202.

[0032] The working principle of a lifting platform for unloading provided by the utility model is as follows:

[0033] When the fruit and vegetable box is placed on the upper surface of the upper bottom plate 201, the two limit plates 210 are driven to move toward the middle by the action of the slide rail 208 in the first groove 207 and the linear motor 209, and the two limit plates 210 are used to limit and fix the two sides of the fruit and vegetable box. Then, the multi-stage telescopic rod 102 is shortened, and then the first rotating motor 103 is used to drive the output end driving gear 104 to rotate, and then the driving gear 104 drives the driven gear 105 to rotate, and then the driven gear 105 drives the connecting shaft 10 7 rotates, and finally the connecting shaft 107 drives the rollers 108 at both ends to rotate, so that the entire lifting platform is driven to move by the rollers 108. When the lifting platform moves to the specified position, the linear motor 209 drives the two limit plates 210 to open to both sides, so that the two limit plates 210 are away from both sides of the fruit and vegetable box. Then, under the action of the second rotating motor 203 and its screw rod 204, the fruit and vegetable box is pushed out of the surface of the upper bottom plate 201 through the slider 205 and the magnetic block 206 on its upper end surface.

[0034] Finally, it should be noted that the above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model.
