Description

Technical Field

[0001] This utility model relates to the field of tea screening technology, specifically to an impurity screening device for tea processing. Background Technology

[0002] Tea leaf selection is an important step in the tea processing process. Its main purpose is to remove impurities such as dust, stems, and broken leaves from the tea leaves, thereby facilitating subsequent processing and sales.

[0003] In existing tea sorting devices, sieves are generally used to sort tea leaves. Multi-stage sieves are often used for sorting. However, the use of such multi-stage sieves in the existing technology has the following drawbacks: the multi-stage sieves cannot be disassembled and left unattended, and the sorting levels cannot be quickly increased or decreased as needed, nor can different screens for different purposes be quickly replaced. Such use is inconvenient. Therefore, an improved impurity sorting device for tea processing is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide an impurity screening device for tea processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tea processing impurity screening device, comprising a support frame, with slide rails fixedly installed on both sides of the upper end of the support frame, and a screening mechanism for screening tea leaves installed on the upper end of the slide rails. The screening mechanism includes a first screening frame, rollers, a second screening frame, slots, inserts, latches, and locking ears. The first screening frame is installed on the upper end of the support frame, and rollers are movably installed at the four corners of the lower surface of the first screening frame via rotating shafts. The second screening frame is installed on the upper end of the first screening frame, and slots are fixedly installed at the four corners of the upper surfaces of both the first and second screening frames. Inserts are fixedly installed at the four corners of the lower surface of the second screening frame, and latches are installed on the surface of the slots. Locking ears are fixedly installed on the outer surface of the inserts.

[0006] Preferably, the support frame is internally provided with a transmission mechanism to aid in screening. The transmission mechanism includes a transmission shaft, a first pulley, an eccentric wheel, and a transmission rod. The transmission shaft is movably mounted on one side of the upper end of the support frame via a bearing. The first pulley is fixedly mounted on the outer surface of the transmission shaft. An eccentric wheel is fixedly mounted on one end of the transmission rod. The transmission rod is movably mounted on the outer surface of the eccentric wheel via a rotating shaft. The end of the transmission rod near the first screening frame is movably connected to the first screening frame via the rotating shaft. By rotating the eccentric wheel in conjunction with the transmission rod, the first screening frame can be driven to move back and forth continuously, thereby aiding in screening and improving the screening effect and efficiency.

[0007] Preferably, an electric motor is fixedly installed inside the support frame, and a second pulley is fixedly installed at the power output shaft end of the electric motor. A transmission belt is sleeved between the first pulley and the second pulley, and the first pulley can be driven to rotate through the electric motor and the second pulley.

[0008] Preferably, the roller is attached to the upper end of the slide rail. The roller surface of this device is provided with a groove. The groove is used to make the roller attach to the upper end of the slide rail, which can ensure the stability of the left and right movement of the first screening frame.

[0009] Preferably, both the first and second screening frames have a discharge port fixedly provided on one side of their surfaces. The screened tea leaves can be easily discharged through the discharge port. The discharge ports of this device should be staggered (the subsequent superimposed screening frames should also follow this rule) so as to facilitate subsequent collection work.

[0010] Preferably, mounting plates are fixedly installed at the four corners of the lower surface of the support frame, which allows the entire device to be easily fixed and installed at the target location.

[0011] 1. This utility model consists of a first screening frame and a second screening frame to form a multi-level screening device. During screening, multiple screening frames can be stacked on top of the second screening frame like building blocks, so as to meet the multi-level tea screening needs as required. At the same time, it is also convenient and quick to change screening frames for different purposes. During installation, the insert block is inserted into the slot, and then the screening frame is fixed by locking the buckle and locking the ear. The whole operation process is convenient and quick.

[0012] 2. When this utility model is in use, the rotation of the eccentric wheel, in conjunction with the transmission rod, can drive the first screening frame and the second screening frame above the first screening frame to move back and forth continuously, thereby helping to improve the screening effect and efficiency.
