Description

Technical Field

[0001] The invention relates to a full-automatic tea leaf storage machine with a multi-layer tea leaf spreading grid frame. Background Art

[0002] Spreading or storing tea leaves is the process of spreading fresh tea leaves thinly in a ventilated environment to make them release moisture and change from brittle to wilted and withered. The fresh leaves that have completed spreading have less water content and soft leaves, which is conducive to the subsequent manual killing of tea leaves. Fresh leaves that are not spread in time will have red stems and red leaves due to their own fermentation, which seriously affects the quality of the raw material. Or killing tea leaves before the spreading time is too late will also affect the aroma of the tea leaves. After the fresh tea leaves are spread for a proper period of time, the nutrients in the fresh leaves will be formed through chemical reactions such as hydrolysis under the action of biological enzymes, which will increase the taste and aroma of the tea leaves. The traditional spreading of fresh leaves is done manually. There are two main methods. One is to spread the fresh leaves in a ventilated and cool place for natural air drying, or to spread them on bamboo mats, wooden mats, etc. This method is relatively primitive and requires a large area. The second is to build a shelf and then place bamboo mats, wooden mats, etc. for spreading. Both methods rely on manual labor and can no longer meet the current needs of continuous tea production.

[0003] At present, tea leaves are generally stored in tea spreading machines in the market. There are many types of tea spreading machines. The present invention mainly discusses a tea storing machine with a multi-layer tea spreading grid.

[0004] In the patent document with patent number ZL201410547874.9, a fully automatic tea spreading machine is disclosed, including a spreading frame, a feeding frame, a first conveyor belt, a second conveyor belt and a third conveyor belt, one end of the feeding frame is fixedly connected to the top of the spreading frame, and the first roller group, the second roller group and the third roller group are arranged in sequence from bottom to top in the spreading frame, and the feeding roller group is installed on the feeding frame, the first conveyor belt is wound around the first roller group, the second conveyor belt is wound around the second roller group, and the third conveyor belt is wound around the third roller group and the feeding roller group; the first roller group and the third roller group are connected by a chain, and the first drive motor and the second drive motor are arranged at the bottom of the spreading frame, the first drive motor is connected to the second roller group by a chain, and the second drive motor is connected to the first roller group by a chain; a transfer belt conveyor is arranged below the first conveyor belt; this patent can improve the spreading efficiency and spreading quality on the basis of quickly completing the spreading of tea leaves, and has the advantage of simple structure.

[0005] Patent No. ZL201420772410.3 discloses an automatic composting machine, comprising a first frame and a second frame, wherein the first frame and the second frame are respectively provided with an upper composting conveyor belt and a lower composting conveyor belt with opposite conveying directions and staggered distribution, and a rolling wheel is provided at the bottom of the second frame. The fresh tea leaves are transmitted to the upper composting conveyor belt and the lower composting conveyor belt through the feeding conveyor belt and spread to cover the upper surfaces of the upper composting conveyor belt and the lower composting conveyor belt respectively, so as to ensure the cleanliness of the fresh tea leaves; after a period of time, the lower rotating motor is stopped to stop the conveying of the lower composting conveyor belt, and the rolling wheel is moved to make the second frame relatively away from the first frame, and at the same time, the conveying rate of the upper composting conveyor belt is controlled by controlling the rotation frequency of the upper rotating motor, thereby controlling the rate and stacking thickness of the fresh tea leaves falling into the lower composting conveyor belt, and improving the efficiency of adjusting the thickness of the fresh tea leaves; after the spreading is completed, the fresh tea leaves are piled and collected through the discharging conveyor belt, and the whole spreading process reduces labor and improves the spreading rate.

[0006] The above-mentioned spreading machine usually uses an elevator to lift the tea leaves and transport them to the spreading frame. At present, the traction components of the elevator include ring chain, plate chain and belt. When working, the material or hopper is lifted to the top with the conveyor belt or chain, and then turned down after bypassing the top wheel to pour the material into the spreading frame. The existing elevator is designed according to the fixed height of the spreading frame, and can only be transported to the highest level of the spreading frame. After spreading, as in the above-mentioned patented technology, the spreading machine mechanically transports the tea leaves from the top layer to the next layer one by one to complete the whole spreading or storing process. This method requires each layer of machinery to run, which firstly leads to high energy consumption and low efficiency. For example, when there is little tea, it is not necessary to spread or store tea leaves from the top layer. Second, a spreading machine can only spread one fresh leaf variety or one level of fresh leaves, and cannot spread or store different fresh leaf varieties or different levels of fresh leaves on each layer.

[0007] Patent No. 202011586865.2 discloses a liftable electric tea spreading machine, including a tea spreading frame, a moving wheel fixedly connected to the bottom of the tea spreading frame, and a driving device fixedly connected to the top of the tea spreading frame, a spreading bottom plate fixedly connected to the top of the moving wheel, and a rotating lifting shaft fixedly connected to the top of the spreading bottom plate; the lifting shaft is driven to rotate by turning on the lifting motor, so that the lifting rope is coiled around the outer surface of the lifting shaft, and then the lifting rotating fixed plate is driven to lift, thereby driving the rotary screen to start rising, and then the switch of the rotating motor is turned on to plug the electric plug-in block into both sides of the lifting shaft, the position of the lifting shaft is fixed, and then the switch of the driving motor is turned on to drive the differential gear to start rotating, and the rotary screen is driven to start differential rotation, and then the tea leaves to be spread can be evenly spread on each rotary screen with the help of a spreading brush to achieve the effect of mechanical and efficient spreading. Although the machine does not require a hoist to transport fresh leaves, it also has the disadvantages of high energy consumption, low efficiency, and one machine for one use.
