[0024] The tobacco drying rack comprises a hanging frame 1 for hanging tobacco for drying. The bottom surface of the hanging frame 1 is fixed with a plurality of leg mechanisms 2 with a leg folding function along its length direction. The support mechanism 2 can support the hanging rod 1 and reduce the possibility of tipping over due to excessive wind or collision, making it more stable. A shielding mechanism 3 for storing tobacco is provided in the middle of the hanging frame 1. When the sun is strong or it rains lightly, the drying tobacco leaves can be gathered in the shielding mechanism 3, and can be covered for stacking at night. Figure 1 As shown, the support mechanism 2 is provided with two groups, and the leg mechanism 2 includes two support legs 201 correspondingly arranged on the bottom surfaces of the two long sides of the hanging frame 1, a foldable support foot for increasing the support area and a folding control device for controlling the expansion or folding of the foldable support foot. The foldable support foot is arranged on the outer side of the lower end of the support leg 201, and the folding control device guided and adapted between the two support legs 201 is connected to the foldable support foot, and the folding or expansion of the foldable support foot is controlled by the lifting and lowering of the folding control device.

[0025] The specific structure of the foldable support leg is as follows: the foldable support leg includes a connecting rod 203 and a bracket 204, a long groove penetrating to the lower end surface is formed on one side of the outer wall of the support leg 201, and the bracket 204 is hinged on the groove wall at the bottom end of the long groove, the outer end of the bracket 204 is hinged to one end of the connecting rod 203, and the other end of the connecting rod 203 is located in the long groove and is hinged to one end of the folding control device.

[0026] The specific structure of the folding control device is as follows: the folding control device includes a movable plate 205, a handle 211 of a U-shaped structure with an opening facing downward is fixed in the middle of the upper end surface of the movable plate 205, and a rotating wheel 209 is rotatably installed inside the movable plate 205 below the handle 211, and a traction rope 208 is wound around the rotating wheel 209 at one end of which is fixedly connected to a partition 210 mounted on the handle 211, and the other end of the traction rope 208 passes through the length direction of the movable plate 205 and is fixedly connected to a limiting member at the notch position of the end of the movable plate 205, the limiting member is positioned and connected to the support leg 201, and the traction rope 208 is pulled through the partition 210 to realize the control of the positioning state of the limiting member and the support leg 201; specifically, both ends of the movable plate 205 are formed with notches that are compatible with the support leg 201, and the end of the movable plate 205 is hinged to the connecting rod 203 at the other end extending into the long groove.

[0027] The specific structure of the limiting member is as follows: the limiting member includes a card block 207, and the card block 207 is elastically connected to the notch position of the movable plate 205 through a spring 206. A plurality of card slots 202 adapted to the card block 207 are provided on the inner side wall of the movable plate 205, and the card block 207 is adapted to the card slot 202 at the corresponding position as the movable plate 205 moves up and down, thereby realizing the positioning connection between the movable plate 205 and the support leg 201, and when the partition 210 pulls the card block 207 inward through the traction rope 208, the positioning state of the limiting member and the support leg 201 is released.

[0028] like Figure 3-4 The outer wall of the outer end of the bracket 204 is hinged with a connecting rod 203, and the outer end of the connecting rod 203 is hinged with a movable plate 205. By moving the movable plate 205 up and down, the connecting rod 203 can be flipped to drive the bracket 204 to flip up and down. The outer end notch of the movable plate 205 is slidably connected to the inner wall of the supporting leg 201. The movable plate 205 can move up and down in the height direction of the supporting leg 201 to adjust the angle of the bracket 204. The internal rotation of the movable plate 205 is connected to a rotating wheel 209, and a traction rope 208 is wound around the outer wall of the rotating wheel 209. Two groups of rotating wheels 209 are provided and are symmetrically distributed inside the movable plate 205, and a traction rope 208 is wound around each group of rotating wheels 209.

[0029] A handle 211 is fixedly connected to the middle part of the upper end surface of the movable plate 205, and the two ends of the partition 210 are mounted on the vertical rods on both sides of the handle 211 to achieve a sliding connection with the handle 211. The handle 211 can be held and the partition 210 can be pulled to release the limit of the movable plate 205 and move the movable plate 205 up and down. The movable plate 205 can be fixed conveniently and quickly through the limit piece, or the limit can be released to move the movable plate 205.

[0030] When the partition 210 is pulled, one end of the traction rope 208 can be stretched, and its stretching direction can be changed by the rotating wheel 209, so that it can drive the block 207 to move inward. The block 207 is elastically connected to the inner wall of the movable plate 205 by the spring 206. When not affected by external force, the block 207 remains in a state of popping outward due to the elastic force of the spring 206, and is engaged with the slot 202 to limit the movable plate 205; when the partition 210 is pulled to make the block 207 move inward due to the pulling force of the traction rope 208, the spring 206 is forced to shrink, and the block 207 is out of contact with the slot 202, so that the limit of the movable plate 205 can be released, and the movable plate 205 can be moved up and down.

[0031] like Figure 5As shown, the specific structure of the shielding mechanism 3 is as follows: the shielding mechanism 3 includes a fixed plate 301, the fixed plate 301 is fixed to the middle part of the hanging frame 1, and connecting blocks 302 are fixed at both ends of the bottom surface of the fixed plate 301, and a shield 303 fixedly connected to the connecting blocks 302 and used for storing tobacco is provided between the two connecting blocks 302, and the outer wall of the shield 303 is fixedly connected to a zipper 304; specifically, the upper end of the shield 303 contacts the top surface of the fixed plate 301.

[0032] The shield 303 is made of cloth, and the connecting block 302 is made of plastic. The shield 303 and the connecting block 302 can be fixed by existing technologies such as bolts. The shield 303 contacts the bottom surface of the fixed plate 301, and the two sides of the shield 303 are fixed to the outer wall of the connecting block 302, while the shield 303 and the fixed plate 301 are not fixed. When the zipper 304 is pulled to the top, the shield 303 is in a closed state, and when the zipper 304 is pulled to the bottom, the top of the shield 303 can be opened to collect tobacco into the shield 303 for rain protection or stacking.

[0033] The specific structure of the hanging frame 1 is as follows: the hanging frame 1 is a frame formed by welding two longitudinal beams and a plurality of transverse beams located between the two longitudinal beams, and the shielding mechanism 3 is located between the two longitudinal beams and fixed to the middle of the longitudinal beams.

[0034] Working principle: When in use, the operator can first place the device on the ground. Figure 2 As shown, the bracket 204 is stored inside the supporting leg 201 for easy carrying. Then the operator can hold the handle 211 on one side and pull the partition 210 upward to drive one end of the traction rope 208 to move. The traction rope 208 changes the pulling direction due to the rotating wheel 209, which can drive the two groups of card blocks 207 to move toward the middle at the same time and break away from the two groups of card slots 202 above. The limit of the movable plate 205 can be released to move the movable plate 205 downward. At this time, the bracket 204 is driven to flip downward by flipping the connecting rod 203. When it flips to the position shown in FIG. Figure 1 When the position is shown, the partition 210 can be loosened, and the elastic force of the spring 206 drives the block 207 to pop out to both sides and engage with the two sets of slots 202 below, so that the position of the movable plate 205 can be fixed, thereby fixing the position of the bracket 204. Then the above steps can be repeated for the support mechanism 2 on the other side, and the stability of the device can be improved by the support mechanism 2, thereby avoiding the problem of easy tipping over due to excessive wind force or collision.

[0035] Then the tobacco can be hung on the hanging rod 1 for drying. When the sun is too strong or it rains, the zipper 304 can be pulled to the bottom and the top of the shield 303 can be opened. The tobacco to be dried can be placed in the shield 303 for shielding. The zipper 304 can be pulled to the top to close the shield 303 to avoid affecting the tobacco. At night, the tobacco can also be placed in the shield 303 for covering. There is no need to remove the tobacco from the hanging rod 1 for covering or stacking, which is more convenient.

[0036] The technical solution supports the hanging frame 1 by means of a leg mechanism 2 with foldable or unfoldable foldable legs at the lower end. The foldable legs are opened to contact the ground, which can improve the overall stability of the device and avoid the problem of the device easily tipping over due to excessive wind or collision. The device can be folded to reduce the occupied space and facilitate storage. When the sun is too strong or it rains lightly, the tobacco can be placed in the shield for shielding, and can also be piled up at night. There is no need to remove all the tobacco for shielding or stacking, which is more convenient. The case has a simple structure, novel design, good stability and reliability, and provides reliable support and collection conditions for tobacco drying.
