Description

Technical Field

[0001] The utility model relates to the technical field of tea production equipment, in particular to a tea withering device. Background Art

[0002] During the tea production process, a withering trough is usually required to wither the tea leaves. Conventional withering troughs generally include a rectangular trough body with a sloped lower portion, a hot air blower installed at the lowest point of the slope, and a mesh plate installed at the upper portion of the inner side of the trough body. During the use of conventional withering troughs, after the tea leaves have withered, they need to be manually collected for transfer to the next process, which is time-consuming and labor-intensive. To this end, the prior art CN 220274761 U proposes a tea withering trough, comprising a withering trough body, the inner wall of which is provided with a feeding device. The motor in the feeding device rotates, driving the withering mesh plate to flip to an inclined state, so that the withered tea leaves slide under the action of gravity into the collection trough, thereby completing the collection of the tea leaves. This eliminates the need for workers to perform tea collection operations, reducing the workload of the workers. However, after the tea leaves fall into the collection trough, they need to be transferred to the next process for withering. At this time, the collection trough needs to be transferred together or the tea leaves need to be removed from the collection trough and then transferred. This operation is relatively cumbersome and still requires a lot of labor. Utility Model Content

[0003] The utility model proposes a tea withering device, which arranges a chain plate type conveying device on the upper inner side of a trough body for placing tea leaves for withering treatment. When the withering treatment of the tea leaves is completed, the chain plate type conveying device is used to convey the tea leaves to a conveyor belt, and then the conveyor belt is used to convey the tea leaves to the next process, so as to solve the problem that the existing withering trough is inconvenient to transfer the tea leaves that have completed the withering treatment to the next process.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is:

[0005] A tea withering device comprises a withering trough, wherein the withering trough comprises a trough body and a chain plate type conveying device arranged at the upper inner portion of the trough body; the chain plate type conveying device has a plurality of chain plates for placing tea leaves, and each of the chain plates is provided with a plurality of ventilation holes; the discharge end of the chain plate type conveying device is provided with a conveyor belt for receiving tea leaves and conveying the tea leaves to the next process.

[0006] Furthermore, both left and right ends of the chain plates of the chain plate type conveyor are hidden in the trough body.

[0007] Furthermore, baffles are provided on the other three sides of the top surface of the chain-plate conveyor except the discharge end. The baffles are movably connected to a plurality of chain plates and fixedly connected to the trough body of the withering trough.

[0008] Furthermore, the conveyor belt is a trough-type conveyor belt.

[0009] Furthermore, a control switch is provided on the trough body of the withering trough, and the control switch, the chain plate conveyor device and the conveyor belt are all electrically connected to the controller.

[0010] Furthermore, the controller is a PLC.

[0011] Furthermore, the conveying direction of the conveyor belt is arranged perpendicular to the conveying direction of the chain plate conveyor device.

[0012] Furthermore, the number of the withering troughs is greater than two, and the number of the conveyor belts is one.

[0013] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0014] 1. This utility model employs a chain-plate conveyor device installed within the upper inner portion of a withering trough, for placing tea leaves for withering. Each of the chain plates of the chain-plate conveyor device is provided with a plurality of ventilation holes, creating a mesh-like structure that effectively dissipates the heat generated by the hot air blower within the trough, accelerating the withering process. Upon completion of withering, the tea leaves are transferred to a conveyor belt via the chain-plate conveyor, which then transports them to the next process step. This improves operator efficiency and reduces workload.

[0015] 2. The utility model sets up multiple withering troughs to share a conveyor belt, which can transfer tea leaves from multiple withering troughs through a single conveyor belt, reducing the number of conveyor belts, lowering equipment costs, and reducing the occupied area. In addition, the single conveyor belt can better cooperate with the fixing equipment in the next process.

[0016] 3. The utility model is provided with a control switch on the trough body of the withering trough to facilitate the operation of the operator. When the tea leaves need to be transferred, the operator starts the control switch, and the controller controls the corresponding chain plate conveyor device and conveyor belt to operate. After the set working time, the controller controls the chain plate conveyor device and conveyor belt to automatically stop working, and the tea transfer task is completed.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] like Figure 1-3 As shown, a tea withering device includes a withering trough 1, which includes a trough body 2 and a chain plate type conveyor 3 arranged on the upper inner portion of the trough body 2. The chain plate type conveyor 3 has a plurality of chain plates 4 for placing tea leaves, and each chain plate 4 has a plurality of ventilation holes 5.

[0024] The chain-plate conveyor 3 is conventional technology and specifically includes a drive motor, two chains, a driving shaft, and a driven shaft. Both the driving shaft and the driven shaft are rotatably mounted within the trough 2. The driving shaft is equipped with two driving sprockets, and the driven shaft is equipped with two driven sprockets. One chain is mounted on a driving sprocket and a driven sprocket on the same side, while the other chain is mounted on the other driving sprocket and the other driven sprocket. The drive motor is fixedly mounted on the trough 2 and connected to the driving shaft to drive the two chains. Several chain plates 4 are sequentially mounted on the two chains and rotate with the chains to achieve material conveyance.

[0025] Among them, the left and right ends of the chain plates of the chain-plate conveyor 3 are hidden in the trough body 2. Correspondingly, the two chains and the corresponding sprockets are also hidden in the trough body 2 to avoid contact by operators and improve safety. Except for the discharge end, the top surface of the chain-plate conveyor 3 is provided with baffles 6 on the other three sides. The baffles 6 are movably connected to a number of chain plates 4 and are fixedly connected to the trough body 2 of the withering trough 1. The movable connection can be understood as: the bottom of the baffle is in contact with the top of the chain plate, and the chain plate 4 can move relative to the baffle 6. The three baffles 6 can confine the tea leaves on the chain-plate conveyor 3 during the withering process.

[0026] The discharge end of the chain plate conveyor 3 is provided with a conveyor belt 7 for receiving tea leaves and conveying the tea leaves to the next process. The conveying direction of the conveyor belt 7 is arranged perpendicular to the conveying direction of the chain plate conveyor 3. In this embodiment, the conveyor belt 7 is a trough conveyor belt, which is convenient for conveying tea leaves.

[0027] The present invention provides a chain-plate conveyor 3 within the upper inner portion of the withering trough 1, which is used to place tea leaves for withering. The chain plates 4 of the chain-plate conveyor 3 are each provided with a plurality of ventilation holes 5. The entire conveying surface acts as a mesh structure, effectively dissipating the heat generated by the hot air blower within the trough 2, thereby accelerating the withering process. After the tea leaves have been withered, the chain-plate conveyor 3 conveys the tea leaves to a conveyor belt 7, which then transports them to the next process step. This improves the operator's work efficiency and reduces their workload.

[0028] The number of withering troughs 1 is greater than two, and the number of conveyor belts 7 is one. In this embodiment, the number of withering troughs 1 is three. The present invention provides multiple withering troughs 1 sharing a single conveyor belt 7, allowing tea leaves from multiple withering troughs 1 to be transferred using a single conveyor belt 7. This reduces the number of conveyor belts 7 required, lowering equipment costs and footprint. Furthermore, a single conveyor belt 7 allows for better coordination with the subsequent tea-withering equipment.

[0029] In addition, a control switch is provided on the trough body 2 of the withering trough 1. The control switch, the chain-type conveyor 3, and the conveyor belt 7 are all electrically connected to a controller. The controller is a PLC. The utility model provides a control switch on the trough body 2 of the withering trough 1 to facilitate operation by the operator. When tea leaves need to be transferred, the operator activates the control switch, and the controller controls the corresponding chain-type conveyor 3 and conveyor belt 7 to operate. After a set operating time, the controller controls the chain-type conveyor 3 and conveyor belt 7 to automatically stop, completing the tea transfer task.

[0030] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
