Description

Technical Field

[0001] The utility model relates to the technical field of mugwort processing, in particular to a storage rack for drying mugwort with adjustable angles. Background Art

[0002] Mugwort is a perennial herb or slightly semi-shrubby plant of the genus Artemisia in the Asteraceae family. The plant has a strong aroma. Mugwort can be used as medicine, which has the effects of warming the meridians, removing dampness, dispelling cold, and stopping bleeding. It can also be added to traditional pastries. Its young shoots and seedlings can also be used as vegetables for human consumption. It has wide application value.

[0003] Mugwort needs to be dried after cleaning. Usually, the cleaned mugwort is placed in a tray, and then the tray is placed inside an air drying room for drying. However, there are some problems. The tray is facing upward, and the air outlet of the air drying room is located on the side of the air drying room. The hot air cannot blow directly to the mugwort, and the drying efficiency is limited. For this reason, we propose an angle-adjustable mugwort drying rack. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an angle-adjustable storage rack for drying mugwort. By adjusting the angle of the placement plate, the mugwort can be aligned with the air outlet, which is conducive to better drying and improves drying efficiency, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an angle-adjustable rack for drying mugwort, comprising a bracket and an angle adjustment mechanism;

[0006] Bracket: The bracket is internally connected with evenly distributed placement boards through a rotating shaft, and the rear sides of the placement boards are hinged with fixed boards through hinges;

[0007] Angle adjustment mechanism: It includes connecting rod two and connecting rod three. Connecting rod three is fixedly sleeved on the outside of the left and right ends of the rotating shaft. Connecting rod three is located on the outside of the bracket. Connecting rod two is rotatably connected between the front end and the rear end of the vertically adjacent connecting rods three. By adjusting the angle of the placing plate, the mugwort can be aligned with the air outlet, which is conducive to better drying and improved drying efficiency.

[0008] Furthermore, the angle adjustment mechanism also includes a connecting rod 1, a spring, a pawl, a fixed column and a ratchet. The middle part of the left side surface of the bracket is rotatably connected to the ratchet. The left side surface of the ratchet is rotatably connected to the connecting rod 1 which is symmetrically distributed front and back. The upper end of the front connecting rod 1 is rotatably connected to the front side of the connecting rod 3 adjacent to the upper end, and the lower end of the rear connecting rod 1 is rotatably connected to the rear side of the connecting rod 3 adjacent to the lower end. The middle part of the left side surface of the bracket is rotatably connected to the pawl, which is located at the lower end of the ratchet. The pawl and the ratchet are arranged in coordination. The middle part of the left side surface of the bracket is fixedly connected to the fixed column, which is located between the pawl and the ratchet. A spring is fixedly connected between the upper end of the pawl and the fixed column to achieve angle adjustment and locking.

[0009] Furthermore, the angle adjustment mechanism also includes a limit plate and a limit column. The middle part of the left side surface of the bracket is rotatably connected to the limit plate, and the limit plate is located on the front side of the pawl. The middle part of the left side surface of the bracket is fixedly connected to the limit column, and the limit column is located at the lower end of the limit plate, so that the worker does not need to use the other hand to open the pawl when rotating the ratchet wheel counterclockwise to reset it, which facilitates operation.

[0010] Furthermore, the angle adjustment mechanism also includes an armrest, which is arranged on the upper rear side of the left side of the ratchet to facilitate the worker to rotate the ratchet and limit the rotation angle of the ratchet.

[0011] Furthermore, the front side of the fixing plate is rotatably connected with evenly distributed buckles, so that the fixing plate is buckled to the upper surface of the hinged placement plate.

[0012] Furthermore, a counterweight is fixedly connected to the front side of the lower surface of the placing plate, so that the center of gravity of the placing plate is moved forward to facilitate rotation.

[0013] Furthermore, the lower outer ends of the brackets are connected to stabilizing frames via bolts, so that the brackets are more stable when the angle is adjusted.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the angle-adjustable wormwood drying rack has the following advantages:

[0015] Place the mugwort to be dried on the upper surface of the placement board in turn. After all the mugwort is placed, put down the fixing plate and buckle the fixing plate to the upper surface of the hinged placement board through the buckle to fix the mugwort to prevent it from falling when adjusting the angle. Turn the ratchet clockwise through the armrest, and the connecting rod one rotates clockwise. The upper end of the connecting rod one on the front side moves and rotates downward, and the lower end of the connecting rod one at the rear end moves and rotates upward, so that the connecting rod three at the upper and lower ends rotate clockwise, and the vertically adjacent connecting rod three and the connecting rod two between the two form a parallelogram, so that the uppermost and lowermost connecting rods three rotate synchronously clockwise, realizing the synchronous angle adjustment of the placement board, and aligning the mugwort to be dried with the air outlet, which is conducive to better drying the mugwort and improving the drying efficiency of the mugwort.

[0024] The working principle of the angle-adjustable storage rack for drying wormwood provided by the utility model is as follows: a worker places the storage rack in an air-energy drying room, holds the fixing plate 3 by hand, and places the wormwood to be dried on the upper surface of the placing plate 2 in sequence. After all the wormwood is placed, the fixing plate 3 is lowered, and the fixing plate 3 is buckled to the upper surface of the hinged placing plate 2 by the buckle 4 to fix the wormwood to prevent it from falling when the angle is adjusted. The ratchet 510 is rotated clockwise by the handrail 501, and the connecting rod 1 502 rotates clockwise.
