Technical Field

[0001] The utility model relates to the technical field of bean sprout production, in particular to an automatic hoisting device for bean sprout production. Background Art

[0002] The production process of bean sprouts includes a soaking basket link, that is, allowing the seeds to fully absorb water and enter the initial growth stage. In this process, in order to improve the soaking efficiency, a loading rack can be used to load multiple seedling baskets, and then the loading rack can be put into and taken out of the soaking pool as a whole to ensure uniform soaking of the seeds and subsequent healthy germination. However, since the loading rack loaded with multiple seedling baskets is heavy, if it is carried by manpower, it is not only laborious but also inefficient. Therefore, an automatic lifting device for lifting the loading rack is urgently needed. Utility Model Content

This scheme adopts the gear and rack to drive, and the driving structure is simple; at the same time, this scheme sets the cross section of the suspension arm to be L-shaped, and the rack can be directly set on the vertical plate of the suspension arm without setting up a rack structure, so as to simplify the suspension arm structure and reduce the deadweight of the suspension arm, thereby improving the stability of the cantilever structure.

[0009] As a preferred embodiment of the utility model, the guide structure includes a slider disposed on the lower side of the sliding seat, a slide rail is disposed on the upper side of the horizontal plate of the suspension arm, and the slider cooperates with the slide rail.

The cross-section of the suspension arm 4 is L-shaped, and a rack 7 is provided on the inner side of the vertical plate of the suspension arm 4. The gear 14 cooperates with the rack 7 to drive the sliding seat 10 to move along the length direction of the suspension arm 4, wherein a guide structure is also provided between the sliding seat 10 and the suspension arm 4 to ensure the stability of the sliding seat 10 during the sliding process. Specifically, the guide structure includes a slider 13 integrally formed on the lower side of the sliding seat 10, and a T-shaped groove is provided on the lower side of the slider 13. A T-shaped slide rail 6 cooperating with the T-shaped groove is installed on the upper side of the horizontal plate of the suspension arm 4, and the slider 13 cooperates with the slide rail 6 for guiding.

[0023] The suspension mechanism also includes a pulley block arranged on one side of the sliding seat 10, and the pulley block is used to hoist the loading frame. Specifically, a second motor 17 and a winding wheel 16 are installed on the upper side of the sliding seat 10, and the output shaft of the second motor 17 is connected to the rotating shaft of the winding wheel 16, and the second motor 17 drives the winding wheel 16 to rotate. The pulley block includes a fixed pulley 18, a movable pulley 19 and a cable.
