Description

Technical Field

[0001] The utility model relates to the technical field of pepper processing equipment, in particular to a pepper fruit screening device. Background Art

[0002] During processing, pepper berries are sun-dried or oven-dried, causing the skin to shrink. They are then pounded or beaten to separate the berries from the stems. While manual screening can remove most of the stems during this process, some are difficult to clean due to their small size. Therefore, further screening and impurity removal is crucial.

[0003] A search revealed a Chinese utility model patent with publication number CN217700090U, which discloses a black pepper screening and impurity removal device. The device comprises multiple support rods and a filter element for screening black pepper. The filter element comprises a connecting ring disposed at one end of the support rods, multiple fixed rods disposed on one side of the connecting rings, a fixed disk disposed at one end of the fixed rods, a motor disposed on one side of the fixed disk, an eccentric shaft disposed on one side of the motor, a rotating frame disposed at one end of the eccentric shaft, and a screening disk disposed at one end of the rotating disk. This application utilizes a motor to drive the eccentric shaft to rotate, thereby driving the screening disk to perform eccentric motion for screening black pepper. However, the screening disk only performs centrifugal motion, which may result in poor screening results. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides a pepper fruit screening device, the main technical problem to be solved is how to improve the screening effect.

[0005] To achieve the above-mentioned purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0006] A pepper fruit screening device includes a support frame, a turntable is rotatably connected to the support frame, a plurality of guide rods are evenly distributed on the turntable, a cylinder is slidably connected to the guide rods, a slag discharge port is fixedly installed at the bottom of the support frame, the slag discharge port is communicated with the bottom of the cylinder, a screening disk is provided in the cylinder, the screening disk is clamped to the cylinder through a plurality of connecting parts, a slide groove is provided on the outer wall of the cylinder, a column is fixedly installed on the support frame, a roller is rotatably connected to the column, when the turntable rotates, the roller drives the cylinder to reciprocate in the vertical direction, and a driving mechanism for driving the turntable to rotate back and forth is provided on the support frame.

[0007] Furthermore, the connecting member includes a protrusion arranged on the edge of the screening plate, a first groove is provided in the protrusion, a spring is provided in the first groove, one end of the spring is fixedly connected to the inner wall of the first groove, and the other end of the spring is fixedly connected to a clamping block, the inner wall of the cylinder is provided with a guide groove corresponding to the size of the clamping block, and a clamping groove is provided at the bottom of the guide groove.

[0008] Furthermore, the clamping block is fixedly connected to a support rod, a spring is sleeved on the support rod, one end of the support rod away from the clamping block is fixedly connected to a limiting block, the limiting block is slidably connected to a second groove, and the second groove is communicated with the first groove.

[0009] Furthermore, the driving mechanism includes a mounting frame fixedly mounted on the support frame, a motor fixedly mounted on the mounting frame, an output shaft of the motor passes through the mounting frame and is fixedly connected to a driving wheel, and a driving belt is connected between the driving wheel and the turntable.

[0010] Furthermore, a slag collecting box is provided at the bottom of the slag discharge port.

[0011] Furthermore, the screening plate is evenly provided with a plurality of filter holes, and the sizes of the plurality of filter holes are different.

[0012] Furthermore, a handle is provided at the center of the screening tray.

[0013] Furthermore, a plurality of screening discs are fixedly mounted on the handle, and the filter holes on the plurality of screening discs decrease in size from top to bottom.

[0014] The beneficial effects of the present invention are:

[0015] 1. Through the sliding connection between the turntable and the cylinder, the chute on the outer wall of the cylinder cooperates with the rollers installed on the support frame, so that the cylinder can make reciprocating motion in the vertical direction while rotating forward and reverse. The screening disk installed in the cylinder moves with the cylinder, and the material is thrown and rolled on the screening disk, making it easier for fine impurities to pass through the sieve holes. The material is more evenly distributed on the screening disk, further improving the screening effect;

[0016] 2. During the screening process, fine particles and impurities in the material can easily clog the sieve holes, affecting the screening efficiency. The forward and reverse rotation and vertical movement of the screening disc can flush the sieve holes through physical impact force, effectively preventing the sieve holes from being clogged and maintaining the continuity and stability of the screening;

[0017] 3. Align the protrusion on the edge of the screening disc with the guide groove, and slide the screening disc downward. During the sliding process, the spring is compressed, and the support rod moves along the second groove toward the center of the screening disc. The block at the end of the support rod is in the first groove. When the block moves to the bottom of the guide groove, the elastic force of the spring drives the block to move away from the center. The block is stuck in the slot and fixes the screening disc in the cylinder, which not only ensures the stability of the screening disc, but also facilitates the user to disassemble and replace it.

[0018] 4. Several screening plates are fixedly installed on the handle. Through the multi-layer screening plates, not only can the impurities mixed in the pepper fruits be effectively screened out, but the pepper fruits can also be graded according to their size to ensure that the quality of the screened pepper fruits is uniform and meet different usage requirements.

The outer wall of the cylinder 4 is provided with a chute 8, and the roller 10 connected to the column 9 drives the cylinder 4 to reciprocate in the vertical direction, so that the screening disc 6 rotates forward and reverse while moving vertically, causing the material to be thrown and rolled on the screening disc 6, making it easier for fine impurities to pass through the sieve holes, so that the material is more evenly distributed on the screening disc 6, further improving the screening effect. After the screening is completed, the handle 62 on the screening disc 6 is grasped and pulled upward, the block 74 disengages the slot 76, the spring 73 is compressed, the screening disc 6 is removed, and the qualified pepper berries are poured out.
