Description

Technical fields:

[0001] This invention relates to the technical field of drying equipment, and more specifically to a drying device for industrial tea production. Background technology:

[0002] Tea, commonly known as tea, generally includes the leaves and buds of the tea plant. China is the birthplace of tea, and the Han Chinese have a custom of using tea as a gift. However, the tea-making process is quite complex, and the drying of tea leaves is one of the important factors affecting the quality of tea, ensuring that each tea leaf is dried evenly. Traditionally, tea leaves are spread out on bamboo mats, which are then placed on drying racks. Both the bamboo mats and the drying racks are quite bulky and inconvenient to move. This method is suitable for large spaces, such as tea factories. However, some industrial tea producers do not have their own tea factories and obtain their tea leaves through purchasing. Their actual tea-making space is limited, so some tea producers set up drying operations on the roof of their factory buildings. However, when not in use, the traditional drying equipment occupies a lot of factory space, and moving it from indoors to the roof and vice versa is also inconvenient. Therefore, there is a need to design a foldable drying rack suitable for industrial tea production, facilitating its storage and transport. Summary of the Invention:

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a drying device for industrial tea production. This drying device can be folded and retracted, making it easy to transport and move after folding and retracting. At the same time, it does not take up much space when folded and retracted, making it convenient to place in the warehouse of the factory without taking up a lot of space.

[0022] Example: See Figures 1 to 5 As shown, a drying device for industrial tea production includes a circular bamboo mat 1 and a strip-shaped square steel 2. (Since the bamboo mat 1 is composed of bamboo strips and weaving threads, the longest bamboo strip is in the middle, and the shortest bamboo strips are on both sides, so the overall shape of the bamboo mat 1 is circular, with parallel cuts on both sides.) A horizontal slot 21 is formed on the front end of the square steel 2, penetrating the rear end of the square steel 2. The bamboo mat 1 is inserted into the slot 21 of the square steel 2. A vertical cylindrical pin is inserted and fixed in the middle of the steel 2, and the cylindrical pin is inserted at the center of the bamboo mat 1; a left limiting sleeve 3 and a right limiting sleeve 4 are respectively fitted on the square steel 2 on the left and right sides of the bamboo mat 1, and the left limiting sleeve 3 and the right limiting sleeve 4 abut against the bamboo strips on both sides of the bamboo mat 1, so that the bamboo strips are perpendicular to the square steel 2, which can restrict the rotation of the bamboo mat 1; the rear end face of the left limiting sleeve 3 and the front end face of the right limiting sleeve 4 are respectively formed with a downwardly extending left ear plate 31 and a right ear plate 41.

[0023] The bamboo mat 1 has an X-shaped rear support rod 5 and a front support rod 6 at its bottom. The upper ends of the rear support rod 5 and the front support rod 6 abut against the rear end face of the left ear plate 31 and the front end face of the right ear plate 41, respectively, and T-shaped positioning pins 7 are inserted into them. The positioning pins 7 are inserted into and fixed to the left ear plate 31 and the right ear plate 41, respectively. The lower middle part of the rear support rod 5 has a guide groove 51 that is parallel to the rear support rod 5. The lower end of the guide groove 51 is inserted with a T-shaped locking bolt 9. The front end of the locking bolt 9 extends out of the rear support rod 5 and is screwed into the longitudinal threaded sleeve 8. The front end of the threaded sleeve 8 is fixed to the front support rod 6. The left limiting sleeve 3 and the right limiting sleeve 4 are screwed with longitudinal limiting bolts 11, which are inserted into the two ends of the slot 21 on the square steel 2, respectively.

[0024] The lower end of the rear support rod 5 is formed with a forward-extending rear support sleeve 52, and the lower end of the front support rod 6 is formed with a rearward-extending front support sleeve 61. Support bolts 10 distributed in front and rear are respectively inserted into the front support sleeve 61 and the rear support sleeve 52, and the support bolts 10 are respectively screwed to the lower ends of the rear support rod 5 and the front support rod 6.

[0025] The length of the rear support rod 5 is equal to the length of the front support rod 6. The lower end face of the left ear plate 31 and the lower end face of the right ear plate 41 are flush. The upper end face of the rear support rod 5 and the upper end face of the front support rod 6 form a semi-circle. The arc radius of the upper end face of the rear support rod 5, the arc radius of the upper end face of the front support rod 6, and the center distance from the lower end face of the right ear plate 41 to the positioning pin 7 are equal. The center distance from the lower end face of the square steel 2 to the positioning pin 7 is greater than the center distance from the lower end face of the right ear plate 41 to the positioning pin 7.

[0026] The lower end face of the rear support rod 5 and the lower end face of the front support rod 6 are semi-circular. The outer walls of the rear support sleeve 52, the front support sleeve 61, the lower end face of the rear support rod 5, and the lower end face of the front support rod 6 are all within the same longitudinal cylindrical surface. The head of the support bolt 10 is longitudinally cylindrical. The outer wall of the head of the support bolt 10 and the outer wall of the lower end face of the rear support rod 5 are within the same cylindrical surface. The lower end of the head of the support bolt 10, the lower end of the outer wall of the front support sleeve 61, the lower end of the outer wall of the rear support sleeve 52, the bottom end of the rear support rod 5, and the bottom end of the front support rod 6 are all located in the same plane to ensure the stability of the drying device.

[0027] The lengths of the rear support sleeve 52 and the front support sleeve 61 are not greater than the longitudinal distance between the rear support rod 5 and the front support rod 6, respectively.

[0028] The thickness of the rear support rod 5 is equal to the thickness of the front support rod 6, and the sum of the thickness of the rear support rod 5 and the longitudinal distance between the rear support rod 5 and the front support rod 6 is equal to the length of the stud on the support bolt 10.

[0029] The thickness of the bamboo mat 1 is equal to the width of the slot 21 on the square steel 2, and the length of the slot 21 is not less than the diameter of the outer ring of the bamboo mat 1.

[0030] The diameter of the stud on the locking bolt 9 is equal to the width of the guide groove 51, the diameter of the outer wall of the screw sleeve 8 is equal to the width of the front support rod 6, and the length of the screw sleeve 8 is equal to the longitudinal distance between the rear support rod 5 and the front support rod 6.

[0031] The lengths of the rear support rod 5 and the front support rod 6 are both less than the length of the square steel 2.

[0032] Working principle: This invention is a drying device for industrial tea production. The drying device uses a bamboo mat 1 as a load-bearing component. When the bamboo strips on the bamboo mat 1 are perpendicular to the square steel 2, as shown... Figure 1 As shown, due to the restriction of the square steel 2, the bamboo mat 1 will not be rolled up, but will be laid flat so that the tea leaves can be spread out on the bamboo mat 1 to dry.

[0033] When the drying device needs to be folded and gathered, the locking bolt 9 can be loosened first, and the limiting bolt 11 can be rotated to make the limiting bolt 11 disengage from the slot 21 of the square steel 2; then the left limiting sleeve 3 and the right limiting sleeve 4 can be moved to both ends of the square steel 2 respectively. After the bamboo mat 1 is separated from the left limiting sleeve 3 and the right limiting sleeve 4, it can be rotated. Rotate the bamboo mat 1 90 degrees. Except for the bamboo strips in the middle of the bamboo mat 1 which are restricted by the square steel 2, the bamboo strips on the other bamboo mat 1 are no longer restricted. Then the bamboo mats 1 on both sides of the square steel 2 are wound around the square steel 2 in the same direction. (To facilitate the bamboo mat 1, the locking bolt 9 can be removed to separate the rear support rod 5 and the front support rod 6.)

[0034] After the bamboo mat 1 is rolled up, the rear support rod 5 and the front support rod 6 are set horizontally against the bamboo mat 1. The rear support rod 5 and the front support rod 6 constrain the rolled bamboo mat 1 to prevent it from unraveling. Then, the limiting bolts 11 on the left limiting sleeve 3 and the right limiting sleeve 4 are tightened respectively. The limiting bolts 11 abut against the end faces of both ends of the square steel 2. Then, the locking bolts 9 are installed to fix the rear support rod 5 and the front support rod 6 together. The folded and folded drying device changes into a columnar structure, which greatly reduces the volume and makes it easy to transport and store without taking up much space.

[0035] The embodiments described are illustrative of the invention and are not intended to limit the invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
