Description

Technical Field

[0001] The utility model patent relates to tea processing equipment, specifically to a tea drying machine. Background Art

[0002] Tea drying is an important step in the tea processing process. It is mainly to remove moisture from tea leaves. The moisture and aroma of tea leaves are dried out by high temperature, and the tea leaves are dried to completely eliminate the grassy smell in the tea leaves, so that the tea leaves can be preserved for a longer time and improve the taste and aroma. The general methods of drying tea leaves include sun drying, drying machine, and roasting. Among them, the use of a dryer is a modern drying method. By controlling the temperature and humidity, the tea leaves can be dried quickly, which can better control the drying effect and improve production efficiency.

[0003] The name is "Energy-saving Tea Drying Oven" (document number CN219301177U, hereinafter referred to as document 1). In document 1, when tea leaves need to be dried, the tea leaves are first placed in a placement frame 4, and then the placement frame 4 is placed in a box body 1. Subsequently, the sealed box door 5 is closed and the box body 1 is started, so that heat is generated inside the box body 1 to dry the tea leaves. After drying, the placement frame 4 containing the tea leaves is taken out of the box body 1 by opening the box door 5.

[0004] The title is "A drying oven for tea production with a layered structure" (document number CN216601502U, hereinafter referred to as document 2). In document 2, fresh tea leaves are laid out on the racks 202 in sequence. The racks 202 are placed inside the main structure 1 and are divided into multiple layers up and down. The electric heating net 103 fixed on both sides of the heat-insulating and heat-resistant casing 101 can be used to dry the fresh tea leaves placed on the racks 202. After the tea leaves are dried, the racks 202 are taken out by rotating the main closing door 203 to proceed to the next step of the tea processing process.

[0005] As mentioned above, in the prior art, the tea drying machine is mainly composed of a box and a mesh frame structure for placing tea leaves, and the tea leaves are heated and dried in the box. When the tea leaves are dried, the mesh frame containing the tea leaves is generally taken out of the dryer box in time by hand. However, in the process of taking tea, the temperature of the mesh frame itself is relatively high after heating, and there is still a relatively high residual temperature or high-temperature hot air in the dryer box. When people put their hands into the box to take tea, they are easily burned, which needs to be improved. Summary of the invention

[0006] The utility model provides a tea drying machine which can automatically take out tea leaves in a drying box, thereby preventing people from being scalded by reaching into the box to take out tea.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted is: a tea drying machine, including a box body, a drying chamber is arranged in the box body, a drying net for holding tea leaves is placed in the drying chamber in an up-and-down stacked manner, and a guide outlet for taking out the drying net is provided on the bottom front side of the drying chamber. The rear end of a table plate located on the front side of the box body and with a flat surface is connected or closely connected to the outer bottom edge of the guide outlet, and a transfer mechanism is provided on the surface of the table plate. The transfer mechanism drives the lowest drying net in the drying chamber to move horizontally from the guide outlet to the outside of the box body.

[0008] Compared with the prior art, the technical effect of the utility model is as follows: after the tea leaves are dried, the drying net at the bottom of the drying room can be driven to move horizontally from the guide outlet to the table outside the box by controlling the moving mechanism. There is no need for personnel to reach into the drying room to take out the drying net, which avoids the situation where tea takers get scalded when manually taking tea cups, and the tea taking operation is safer.

[0015] The following is combined with Figure 1-6 And related content, the utility model is further described in detail:

[0016] A tea drying machine comprises a casing 10, in which a drying chamber 11 is arranged. A drying net 40 for holding tea leaves is placed in the drying chamber 11 in an up-and-down stacked manner. A guide outlet 12 for taking out the drying net 40 is provided at the front side of the bottom of the drying chamber 11. A rear end of a table 20 located at the front side of the casing 10 and having a flat surface is connected or closely connected to the outer bottom edge of the guide outlet 12. A transfer mechanism 30 is provided on the surface of the table 20. The transfer mechanism 30 drives the lowest drying net 40 in the drying chamber 11 to move horizontally from the guide outlet 12 to the outside of the casing 10.

[0017] In the above scheme, when drying tea leaves, the tea leaves are placed in the drying net 40, and the drying net 40 is heated and dried inside the drying chamber 11. After the tea leaves are dried, the drying net 40 containing the tea leaves can be taken out from the outlet 12. At this time, by controlling the moving mechanism 30, the drying net 40 at the bottom of the drying chamber 11 can be driven to move horizontally from the outlet 12 to the table 20 outside the box 10, and there is no need for personnel to reach into the drying chamber 11 to take out the drying net 40, thereby avoiding the situation where the tea taker is scalded by manually taking the tea cup, and the tea taking operation is safer.

[0018] As a preferred solution, the guide plate slit 31 arranged horizontally on the table 20 extends from the front end of the table 20 into the guide outlet 12, and the movable seat 33 connected to the conveyor chain 36 is placed in the guide plate slit 31 to form a guide limit fit, and the toggle plate 34 moves with the movable seat 33 between the front edge of the table 20 and the rear side wall of the front frame rod of the lowest drying net 40 in the drying chamber 11. In this solution, when the movable seat 33 is driven by the conveyor chain 36 to move in the guide plate slit 31 to the rear side of the front frame rod of the last layer of the drying net 40 in the drying chamber 11, the conveyor chain 36 can be driven in reverse to make the toggle plate 34 move in the reverse direction, and the toggle plate 34 can toggle the last layer of the drying net 40 in the drying chamber 11 to move outward from the guide outlet 12 to the table 20.

[0019] Furthermore, the upper middle part of the vertical toggle plate 34 is hingedly connected to the upper edge of the rear side of the movable seat 33, the axis of the hinge axis is located in the horizontal direction and perpendicular to the displacement direction of the movable seat 33, the upper end of the toggle plate 34 protrudes from the table surface of the table plate 20 and the protruding height is less than the distance between the mesh body of the drying net 40 and the lower frame surface of the frame edge. In this solution, in order to better illustrate the state change of the toggle plate 34 during the movement process, combined with Figure 6 As shown, the toggle plate 34 is hinged to the upper edge of the rear side of the movable seat 33 in a hinged manner. When the drying net 40 at the bottom of the drying chamber 11 needs to be taken out, the movable seat 33 is controlled to move toward the guide outlet 12, and the plate body of the toggle plate 34 will be pressed against the front side of the front frame rod of the bottom drying net 40, so that the plate body of the toggle plate 34 naturally flips to a horizontal direction to avoid the front frame rod of the drying net 40. As the movable seat 33 continues to move, the toggle plate 34 can immediately move to the inner rod surface side position of the front frame rod of the bottom drying net 40. At this time, the toggle plate 34 naturally flips to the plumb bob direction under the action of the gravity of the lower body and abuts against the rear side of the movable seat 33, and then the movable seat 33 is controlled to move toward the front of the table 20, and the toggle plate 34 can push the inner rod surface of the front frame rod of the lowest drying net 40, so that the drying net 40 can be moved out through the guide outlet 12. In this way, the movement interference between the shifting plate 34 and the drying net 40 can be avoided, and the drying net 40 at the bottom of the drying chamber 11 can be normally moved out.

[0020] It should be noted that since the length of the lower half of the toggle plate 34 divided by the hinge position is greater than the upper half, in a natural state, the lower half of the toggle plate 34 will rest against the rear side of the movable seat 33 under the action of gravity. In the process of moving the drying net 40, the rear side of the movable seat 33 can limit the deflection of the toggle plate 34.

[0021] As a preferred embodiment, guide frames 32 with upright frame surfaces and parallel to each other are arranged on the left and right sides of the movable seat 33, the upper rod surface of the upper frame rod of the guide frame 32 is at the same height as or lower than the height of the table top 20, and the guide frame 32 extends backward from the front end of the table top 20 to the inner side of the guide outlet 12, and the left and right sides of the movable seat 33 are connected with support rollers 35a in the horizontal direction of the wheel core, the support rollers 35a are located in the guide track holes 321 on the guide frame 32 and form a rolling fit with the lower hole wall, and the movable seat 33 is connected with a limiting roller 35b with the wheel core located in the plumb direction, the limiting roller 35b is located between the upper and / or lower frame rods of the guide frame 32 and forms a rolling fit with the upper and / or lower frame rods of the guide frame 32. The two guide frames 32 arranged symmetrically and at intervals form a path for the movable seat 33 to move. The cooperation between the support roller 35a and the guide track hole 321 on the guide frame 32 can support the movable seat 33 and enable the movable seat 33 to move along the extension direction of the guide track hole 321; and the cooperation between the limiting roller 35b and the frame rod of the guide frame 32 can limit the horizontal deviation of the movable seat 33. The common arrangement of the support roller 35a and the limiting roller 35b can ensure that the movable seat 33 is stably limited on the guide frame 32 for movement, so that the toggle plate 34 can normally push the drying net 40 on the platen 20.

[0022] As a preferred solution, in order to prevent the upper drying net 40 from being pressed on the lowest drying net 40, which makes it difficult for the shifting plate 34 to shift the lowest drying net 40 to move, a movable plate 50 is provided at the bottom of the drying chamber 11. The movable plate 50 is respectively located at a supporting position for supporting the second-to-last drying net 40 at the bottom of the drying chamber 11 or at a evacuation position separated from the second-to-last drying net 40 at the bottom of the drying chamber 11. In this solution, by controlling the movable plate 50 to swing with the power shaft 51, the second-to-last drying net 40 at the bottom of the drying chamber 11 can be supported, so that the second-to-last drying net 40 at the bottom and the drying nets 40 above it are lifted up, and the lowest drying net 40 can be freed from the pressure of the upper drying net 40 and become free, and the shifting plate 34 can then easily shift and move the lowest drying net 40 out. After the bottom drying net 40 is moved out, the movable plate 50 can be controlled to swing to an avoidance position separated from the second to last drying net 40 at the bottom of the drying chamber 11. At this time, the drying net 40 in the drying chamber 11 can fall freely, and the second to last drying net 40 at the bottom falls to the lowest position and waits to be moved out after drying is completed.
