Technical Field

[0001] This utility model relates to the technical field of coffee bean sorting devices, specifically a coffee bean sorting device of the same particle size for coffee processing. Background Technology

[0002] Coffee bean sorting devices are commonly used in the field of coffee bean sorting. Coffee bean sorting is to classify coffee beans according to different sizes according to needs. Coffee beans of different sizes have different qualities. Mixing coffee beans of different sizes together will affect the taste of coffee. Therefore, it is necessary to grade coffee beans according to different sizes.

[0003] Most current screening devices directly screen coffee beans through a sieve. However, in this process, workers put the coffee beans into the sieve at once, which causes the coffee beans to accumulate and form a "layer" on the sieve surface. The lower layer of beans cannot contact the sieve, resulting in a significant decrease in screening efficiency. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a coffee bean screening device of the same particle size for coffee processing.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a coffee bean screening device of the same particle size for coffee processing, including a screening box, wherein three inclined mounting frames are provided in the screening box, and screens are fixedly installed in the mounting frames. The diameter of the screen holes of the three screens decreases from top to bottom. A feeding hopper is installed at one end of the top of the screening box, and two symmetrically arranged feeding plates are movably inserted at the bottom of the feeding hopper. One of the feeding plates is fixedly provided with a movable plate at one end of the outer wall of the feeding hopper. A rectangular groove is opened on the movable plate, and a pusher is rotatably provided in the rectangular groove. The pusher is Y-shaped in shape, and the end of the pusher abuts against the side wall of the rectangular groove. An arc groove is opened at the diagonal of the rectangular groove.

[0006] Preferably, a rotating rod is rotatably provided at the bottom of the screening box, and a cam is fixedly provided at one end of the rotating rod inside the screening box. The top of the cam abuts against the bottom of the mounting frame. A first motor is fixedly provided on the outer wall of the screening box near the rotating rod. The output end of the first motor is coaxially fixedly provided on the rotating rod. A connecting rod is fixedly provided between the upper and lower surfaces of the adjacent mounting frames. Four long rods arranged in a rectangular pattern are fixedly provided on the top of the upper mounting frame, and the top of the long rods penetrates through the top of the screening box. A stop block is fixedly provided on the top of the long rods. A spring is sleeved on one end of the long rod on the outer wall of the screening box, and the upper and lower ends of the spring are fixedly provided between the stop block and the outer wall of the screening box.

[0007] Preferably, a protective cover is fixedly provided on the side wall of the screening box near the two feeding plates. A gear is rotatably provided in the middle of the protective cover. Two symmetrically arranged toothed plates are meshed on the gear. The ends of the two toothed plates away from the gear are respectively fixedly provided on the corresponding movable plates.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. The pusher block is driven to rotate by the second motor, which drives the movable plate and the feeding plate to open and close intermittently, so as to realize the quantitative and intermittent discharge of coffee bean raw materials, avoid the formation of "accumulation layer" on the screen surface due to one-time feeding, and allow the lower layer of beans to fully contact the screen, reducing the problem of decreased screening efficiency caused by accumulation.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-5 As shown, this utility model provides a coffee bean screening device of the same particle size for coffee processing, including a screening box 1. The screening box 1 is provided with three inclined mounting frames 11. Screens 12 are fixedly installed in the mounting frames 11. The diameter of the screen holes of the three screens 12 decreases from top to bottom. A feeding hopper 3 is installed at one end of the top of the screening box 1. Two symmetrically arranged feeding plates 31 are movably inserted at the bottom of the feeding hopper 3. A movable plate 32 is fixed at one end of the feeding plate 31 on the outer wall of the feeding hopper. A rectangular groove 33 is opened on the movable plate 32. A pusher block 35 is rotatably installed in the rectangular groove 33. The pusher block 35 is Y-shaped. The end of the pusher block 35 abuts against the side wall of the rectangular groove 33. An arc groove 34 is opened at the diagonal of the rectangular groove 33.

[0020] A rotating rod 17 is rotatably mounted at the bottom of the screening box 1. A cam 18 is fixedly mounted at one end of the rotating rod 17 inside the screening box 1. The top of the cam 18 abuts against the bottom of the mounting frame 11. A first motor 19 is fixedly mounted on the outer wall of the screening box 1 near the rotating rod 17. The output end of the first motor 19 is coaxially fixedly mounted on the rotating rod 17. A connecting rod 13 is fixedly mounted between the upper and lower surfaces of adjacent mounting frames 11. Four rectangularly distributed long rods 14 are fixedly mounted on the top of the upper mounting frame 11, and the top of the long rods 14 penetrates the top of the screening box 1. A stop block 15 is fixedly mounted on the top of the long rods 14. A spring 16 is sleeved on one end of the long rod 14 on the outer wall of the screening box 1, and the upper and lower ends of the spring 16 are fixedly mounted between the stop block 15 and the outer wall of the screening box 1. Through the above operation, the filter screen 12 can be shaken up and down, so as to quickly screen the raw materials.

[0021] A protective cover 4 is fixedly installed on the side wall of the screening box 1 near the two feeding plates 31. A gear 41 is rotatably installed in the middle of the protective cover 4. Two symmetrically arranged toothed plates 42 are meshed on the gear 41. The ends of the two toothed plates 42 away from the gear 41 are respectively fixed on the corresponding movable plates 32. By meshing the two toothed plates 42 together on the gear 41, the two feeding plates 31 can move towards each other or away from each other at the same time, forming an intermittent opening and closing operation.

[0022] A second motor 36 is fixedly installed on the outer wall of the screening box 1 near the lower part of the push block 35. The output end of the second motor 36 is coaxially fixed at the middle end of the push block 35. The second motor 36 mainly provides power for the rotation of the push block 35, which facilitates operation by the staff.

[0023] An inclined discharge plate 2 is fixedly installed on the outer wall of the screening box 1 near the bottom of each mounting frame 11. The discharge plate 2 can conveniently discharge the screened raw materials in a concentrated manner, thereby increasing the practical effect of the device.

[0024] Working principle: During use, the operator can put the raw materials to be screened into the feed hopper 3 at once, and then start the second motor 36. At this time, the second motor 36 will drive the push block 35 to rotate. One end of the push block 35 will abut against one side of the rectangular groove 33. At this time, the push block 35 will push the movable plate 32 to move. The movable plate 32 will move towards the end of the push block 35 that is in contact with the rectangular groove 33. However, when the push block 35 rotates into the arc groove 34, the other end of the push block 35 will abut against the other side of the rectangular groove 33. At this time, the push block 35 will push the movable plate 32 to move to the other side. Therefore, when the second motor 36 drives the push block 35 to rotate, The pusher 35 will push the movable plate 32 to rotate back and forth continuously. Since the two feeding plates 31 at the bottom of the feeding hopper 3 are connected by the toothed plate 42 and the gear 41, when one feeding plate 31 moves towards the feeding hopper 3, the other feeding plate 31 will move towards the feeding hopper 3 at the same time. At the same time, when the feeding plate 31 moves away from the feeding hopper 3, the other feeding plate 31 will also move away from the feeding hopper 3 at the same time. Therefore, the opening and closing of the feeding plates 31 can be controlled intermittently through the above operation, so that the coffee bean raw materials in the feeding hopper 3 can be discharged intermittently and quantitatively, avoiding the formation of a "piling layer" of beans on the screen surface due to one-time feeding, and the lower layer of beans cannot contact the screen, which greatly reduces the screening efficiency.

[0025] The coffee beans that fall into the screening box 1 will then fall onto the screen 12 below. The screening box 1 contains multiple sets of inclined screens 12, with the largest diameter screen 12 at the top, decreasing in diameter sequentially downwards. Therefore, the coffee beans that remain on the screen 12 are always of uniform size. The coffee beans will eventually be discharged through the bottom discharge plate 2 of the screen 12. Workers can use collection frames at the bottom of each discharge plate 2 to collect the discharged coffee beans. This device can screen coffee beans of different diameters simultaneously, improving its practicality. While the screens 12 are screening the coffee beans, the first motor 19... The rotating rod 17 will rotate, and the end of the cam 18 fixed on the rotating rod 17 will push the top mounting frame 11 upward. However, when the end of the cam 18 rotates downward, the mounted frame 11, after moving upward, will be pulled downward by the spring 16 on the top long rod 14. Subsequently, as the cam 18 rotates again, it will push the mounting frame 11 upward again. Therefore, when the first motor 19 works, it can drive the mounting frame 11 to move up and down continuously. At this time, the raw material on the screen 12 will be shaken, causing the raw materials to separate. The raw materials smaller than the current diameter of the screen 12 will fall to the bottom for screening. The above operation can improve the screening efficiency.

The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
