Description

Technical Field

[0001] This utility model relates to the field of coffee bean sorting technology, and more specifically, to a high-efficiency coffee bean sorting device. Background Technology

[0002] Coffee beans are the seeds from the fruit of the coffee plant. There are two main types of coffee beans: Arabica and Robusta. During the coffee bean production process, sorting machines are used to separate coffee beans of different sizes to ensure the quality of the finished coffee. However, most existing coffee bean sorting devices can only sort by size and are unable to remove lighter impurities from the beans.

[0003] A search revealed that Chinese patent CN220738505U discloses a coffee bean sorting device. This device uses an air separation mechanism to add coffee beans into the air separation box from the feed hopper. A first drive motor drives a first transmission shaft and fan blades to rotate, thereby accelerating the airflow inside the air separation box. This blows up light impurities in the coffee beans and discharges them through the dust exhaust pipe, thus removing light impurities from the coffee beans and ensuring the quality of the coffee.

[0004] When the above-mentioned screening device is in use, the fan blades rotate to generate air, which can blow up the light impurities contained in the coffee beans and discharge them through the dust exhaust pipe. However, the coffee beans fall at a relatively fast speed, and some impurities will be mixed in with the coffee beans, making it inconvenient to fully clean the impurities in the coffee beans, resulting in poor performance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency coffee bean sorting device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency coffee bean screening device, comprising a screening box, a box cover, and locking bolts. The top of the screening box is fixed to the box cover by the locking bolts. Two filter frames are provided at the bottom of the box cover, and the two filter frames are fixedly installed on the front and rear sides of the screening box, respectively. A screening assembly is provided between the two filter frames. The screening assembly includes two lead screws, four extrusion sleeves, a horizontal plate, a square filter sleeve, a baffle, a hydraulic cylinder, and a U-shaped frame. The top ends of the two lead screws are fixedly connected to the box cover, and the bottom ends of the two lead screws pass through the horizontal plate and the four extrusion sleeves, respectively. The top end of the square filter sleeve is fixedly connected to the horizontal plate. The U-shaped frame is fixedly installed at the bottom end of the square filter sleeve. The two ends of the hydraulic cylinder are fixedly connected to the baffle and the U-shaped frame, respectively. A rotating assembly is provided at the bottom of the screening box. The rotating assembly includes a mounting frame, a motor, and a fan blade.

[0007] Furthermore, the motor is fixedly mounted on the mounting bracket, and the end of the motor's output shaft is fixedly connected to the fan blade rod.

[0008] Furthermore, an air inlet hopper is movably provided at the top of the fan blade rod, and an air pipe is fixedly connected to the top of the air inlet hopper. The other end of the air pipe is fixedly connected to one of the filter frames, and a dust outlet hopper is fixedly connected to the front side of the other filter frame.

[0009] Furthermore, three filter frames are movably arranged at the bottom of the U-shaped frame, and the bottom ends of the two lead screws pass through the three filter frames.

[0010] Furthermore, a pressing rod is movably connected to the mounting frame via a bearing, and a protrusion is provided on the top of the pressing rod, with the top of the protrusion fixedly connected to the screening box.

[0011] As can be seen, the above technical solution facilitates the up-and-down movement of coffee beans inside the sorting box.

[0012] Furthermore, a bevel gear set is provided on the rear side of the extrusion rod, and the extrusion rod and the fan blade rod are connected by the bevel gear set.

[0013] It can be seen that the above technical solution is designed to facilitate the rotation of the extrusion rod.

[0014] Furthermore, a support frame is fixedly connected to the bottom of the mounting frame, and four connecting rods are provided on the support frame, with the top ends of the four connecting rods fixedly connected to the screening box.

[0015] It can be seen that the above technical solution is designed to prevent the screening box from deflecting when it moves vertically.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a motor to drive the fan blade rod to rotate, which generates airflow to clean impurities from coffee beans. The piston rod on the hydraulic cylinder retracts, causing the baffle to move downwards. The coffee beans are initially screened through a square filter screen. Similarly, the coffee beans can be screened multiple times through three filter frames. The structure is simple, can efficiently screen coffee beans, and can easily and thoroughly clean impurities from coffee beans, resulting in good performance.

[0018] 2. In this utility model, the fan blade rod can drive the extrusion rod to rotate through the bevel gear set. Through the cooperation of the extrusion rod and the protrusion, the screening box can be moved up and down, thereby causing the coffee beans in the screening box to shake up and down, so as to fully screen the coffee beans. At the same time, the screening box drives the four connecting rods to move vertically on the support frame, which can prevent the screening box from deflecting when moving vertically. The structure is simple and easy to use. Attached Figure Description

The sorting assembly 12 includes two lead screws 1201, four extrusion sleeves 1202, a horizontal plate 1203, a square filter sleeve 1204, a baffle 1205, a hydraulic cylinder 1206, and a U-shaped frame 1207. 7. The top ends of the two lead screws 1201 are fixedly connected to the box cover 2, and the bottom ends of the two lead screws 1201 pass through the horizontal plate 1203 and the four extrusion sleeves 1202 respectively. The top end of the square filter screen sleeve 1204 is fixedly connected to the horizontal plate 1203. The U-shaped frame 1207 is fixedly installed at the bottom end of the square filter screen sleeve 1204.

[0028] Furthermore, the motor 902 is fixedly mounted on the mounting bracket 901, and the output shaft end of the motor 902 is fixedly connected to the fan blade rod 903. The bottom of the U-shaped frame 1207 is movably provided with three filter frames 1208, and the bottom ends of the two lead screws 1201 pass through the three filter frames 1208.

[0029] Furthermore, a pressing rod 904 is movably connected to the mounting frame 901 via a bearing. A protrusion 8 is provided on the top of the pressing rod 904, and the top of the protrusion 8 is fixedly connected to the screening box 1. A bevel gear set 905 is provided on the rear side of the pressing rod 904, and the pressing rod 904 is connected to the fan blade rod 903 via the bevel gear set 905.

The coffee beans at the top of the horizontal plate 1203 pass through the square filter sleeve 1204, and the coffee beans are initially screened through the square filter sleeve 1204. Similarly, the coffee beans can be screened multiple times through the three filter frames 1208. The structure is simple and can efficiently screen coffee beans. At the same time, it is convenient to thoroughly clean the impurities in the coffee beans. The effect is good. Rotate the extrusion sleeve 1202 and move it away from the lead screw 1201, thereby releasing the fixation between the filter frame 1208 and the lead screw 1201, and take out the coffee beans in the filter frame 1208.
