[0025] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments may be combined with each other.

[0026] As Figures 1 to 7 shown in the embodiment of the foldable drying device for tea processing of the present utility model, the foldable drying device for tea processing includes a connecting plate 1, a middle cross beam 2 and a rotating cross beam 3, and further includes three longitudinal beams 4; the connecting plate 1 is fixedly connected to one end of the middle cross beam 2, and the other end of the middle cross beam 2 is fixedly connected to the longitudinal beam 4; the connecting plate 1 is rotatably connected to one end of the rotating cross beam 3, and the other end of the rotating cross beam 3 is fixedly connected to the longitudinal beam 4.

[0027] On the same connecting plate 1, one middle cross beam 2 and two rotating cross beams 3 are provided, wherein the two rotating cross beams 3 are arranged on both sides of the middle cross beam 2. One connecting plate 1, one middle cross beam 2 and two rotating cross beams 3 provided on the connecting plate form a group. Multiple groups of connecting plates 1, middle cross beams 2 and rotating cross beams 3 are arranged at equal intervals in the height direction. The multiple middle cross beams 2 are fixedly connected by longitudinal beams 4, and the multiple rotating cross beams 3 on the same side of the middle cross beam 2 are fixedly connected by longitudinal beams 4, that is, the three longitudinal beams 4 are respectively connected to one middle cross beam 2 and two rotating cross beams 3 arranged at equal intervals in the height direction.

[0028] The lower end surface of the longitudinal beam 4 and the lower end surface of the lowermost connecting plate 1 are fixedly provided with universal wheels 5 for landing, so as to facilitate the displacement of the device in the folded state and the unfolded state, and also facilitate the staff to pull the rotating cross beam 3 to expand.

[0029] As Figures 1 to 3 shown, it is a schematic diagram of the process of gradually unfolding the device. Figure 1 is the folded state, at this time it can be conveniently stored and the space is saved; Figure 2 is the state where the two rotating cross beams 3 are in the same straight line after unfolding. At this time, it is convenient to place drying tools (such as bamboo strips) on each layer; Figure 3 is the fully unfolded state. At this time, it can effectively support the drying tools and the drying tools cannot be removed.

[0030] When it is necessary to unfold the folded state, the staff can pull the rotating cross beam 3 away from the middle cross beam 2, and it can be conveniently unfolded with the assistance of the universal wheels 5 below the longitudinal beam 4; when it is necessary to fold the unfolded state, the staff can pull the rotating cross beam 3 close to the middle cross beam 2.

[0031] This device adopts a circumferential folding scheme, which greatly saves the space occupancy rate in the folded state, has a good folding effect, and has a simple structure and a simple folding process.

[0032] In an embodiment of the present application, preferably, the connecting plate 1 has a rectangular shape with semi - circles on both sides. The middle cross - beam 2 is fixedly connected to the rectangle of the connecting plate 1 and is perpendicular to the rectangle side. The circumferences of the two semi - circles on both sides are the rotation directions of the two rotating cross - beams 3. In this way, the two rotating cross - beams 3 can be parallel to the middle cross - beam 2 in the folded state, having a better folding effect and saving more placement space.

[0033] In an embodiment of the present application, preferably, the end parts of the two rotating cross - beams 3 are fixedly provided with rotating rings 31, and the connecting plate 1 is fixedly provided with a rotating shaft 11, and the rotating ring 31 is sleeved on the rotating shaft 11.

[0034] In an embodiment of the present application, preferably, the outer circumference of the rotating ring 31 is provided with teeth, and the teeth on the outer circumferences of the two rotating rings 31 are meshed with each other. In this way, when the staff operates to unfold or fold, only one rotating cross - beam 3 needs to be pulled to complete the operation, further simplifying the folding process.

[0035] In an embodiment of the present application, preferably, the connecting plate 1 further includes a lower cover 12, and the lower cover 12 is fixedly arranged on the lower end surface of the connecting plate 1, and the rotating cross - beam 3 is located between the connecting plate 1 and the lower cover 12. The setting of the lower cover 12 facilitates the assembly of this device.

[0036] In an embodiment of the present application, preferably, a sector - shaped rotating groove 13 is arranged inside the connecting plate 1. One side of the rotating groove 13 is perpendicular to the middle cross - beam 2, and the two rotating grooves 13 are symmetrically arranged on both sides of the middle cross - beam 2. One end of the rotating cross - beam 3 rotates in the rotating groove 13. The rotating groove 13 can be located inside both the connecting plate 1 and the lower cover 12 together. The rotating groove 13 plays a role in limiting the rotation range of the rotating cross - beam 3.

[0037] In an embodiment of the present application, preferably, the central angle of the sector - shaped rotating groove 13 is set to 90 degrees or 120 degrees. When the central angle is 90 degrees, as Figure 2 shown, the two rotating cross - beams 3 are limited to the position where they are at most in the same straight line. At this time, the middle cross - beam 2 is perpendicular to the two rotating cross - beams 3. At this time, the length of the rotating cross - beam 3 can be set to be less than that of the middle cross - beam 2. After placing drying tools (such as bamboo strips) on each layer, the center of the drying tools is not at the connecting plate 1 but on the middle cross - beam 2. At this time, the effective support for the drying tools can be completed. When the central angle is 120 degrees, as Figure 3As shown, the two rotating crossbeams 3 are limited to a position where the angle between each of them and the middle crossbeam 2 is 120 degrees, and the angle between the two rotating crossbeams 3 is also 120 degrees. At this time, the lengths of the middle crossbeam 2 and the two rotating crossbeams 3 can be set to be equal, and at this time, the support for the drying tool is the most stable. Of course, the central angle of the rotating groove 13 can also be set to be approximately 90 degrees or 120 degrees, and angles between 90 degrees and 120 degrees can be set, or angles less than 90 degrees or greater than 120 degrees can be set, as long as the drying tool can be effectively supported.

[0038] In an embodiment of the present application, preferably, two universal wheels 5 are provided on the lower end surface of the connecting disc 1. The two universal wheels 5 are symmetrically arranged on both sides of the middle crossbeam 2, and the two universal wheels 5 are far away from each other and close to the side edges of the connecting disc 1. Thus, when the device is in a folded state, the two universal wheels 5 below the connecting disc 1 cooperate with the universal wheels 5 below the longitudinal beam 4, and the five universal wheels can form an isosceles trapezoid contour. At this time, the device can be vertically placed without relying on anything, which is convenient for storage and also convenient for the staff to unfold or fold.

[0039] In an embodiment of the present application, preferably, a support plate 21 is provided at one end of the middle crossbeam 2 close to the longitudinal beam 4 to better support the drying tool (such as bamboo strips); of course, support plates can also be provided on the rotating crossbeams 3, but the support plates need to be arranged in a staggered manner so that they do not interfere with each other when in the folded state.

[0040] In an embodiment of the present application, preferably, the upper end surfaces of the same group of connecting disc 1, middle crossbeam 2, and the part of the rotating crossbeam 3 outside the connecting disc 1 are flush to more stably support the drying tool.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
