Description

Technical Field

[0001] The utility model relates to the technical field of color sorters, in particular to a discharge hopper structure of a color sorter. Background Technique

[0002] A color sorter is a device that automatically sorts out different-colored particles in granular materials based on the differences in the optical properties of the materials. It uses photoelectric detection technology and is widely used in the fields of bulk material or packaged industrial products and food quality inspection and grading. In a color sorter, the material enters the discharge hopper through the sorting area, and the discharge hopper separates materials of different qualities and centrally conveys them to a unified storage device. Among them, how to separate the better-quality part of the material and transfer it to the color sorter is the key, and the transfer effect will directly affect the color sorting effect of the color sorter.

[0003] The utility model with the publication number of CN215940710U discloses a discharge hopper of a color sorter, which includes an outer hopper. The bottom end of the outer hopper outer wall is fixedly sleeved with a second connecting sleeve, the second connecting sleeve is fixedly sleeved on the top end of the connecting cylinder outer wall through a second fixing bolt, the bottom end of the connecting cylinder outer wall is fixedly sleeved with a first connecting sleeve through a first fixing bolt, the front side of the bottom end of the first connecting sleeve is fixedly connected to the top end of the defective product discharge port, and the rear side of the bottom end of the first connecting sleeve is fixedly connected to the top end of the good product discharge port.

[0004] As shown in the above-mentioned utility model, the existing discharge hopper of a color sorter generally sets the good product discharge port to be inclined. When the material enters the good product discharge port, it first contacts the buffer plate. A number of springs fixedly connected to the bottom end of the buffer plate can effectively reduce the impact force of the material collision. At the same time, a buffer pad is filled on one side of the good product filter plate to prevent the good product from colliding when entering the good product filter pipe. However, this method reduces the flow rate of the material, making the material prone to blockage in the discharge hopper. Moreover, although the discharge port is set as an inclined structure in this way, the inclination angle of this inclined structure is small, making the material prone to splash when discharged, resulting in unnecessary waste.

[0028] Refer to Figure 1-6 , the present invention provides the following two technical solutions:

[0029] The first implementation method: A color sorter discharge hopper structure includes:

[0030] The color sorter main body 1, and a plurality of discharge hoppers 11 are arranged at equal intervals at the lower end of one side of the color sorter main body 1.

[0031] The discharge hopper 11, the top of the discharge hopper 11 is connected to the color sorter main body 1 through a discharge port, a guide port 12 is arranged at the bottom of the discharge hopper 11, a slow-moving material mechanism is arranged in the inner cavity of the discharge hopper 11, the slow-moving material mechanism includes a movable sleeve 13 arranged in the inner cavity of the discharge hopper 11, the top end of the movable sleeve 13 is connected to the inner wall of the upper end of the discharge hopper 11 through an elastic sealing sleeve 14, and the elastic sealing sleeve 14 plays a sealing role to prevent materials from falling into the gap between the movable sleeve 13 and the inner cavity of the discharge hopper 11. A screw blade 15 is fixed inside the movable sleeve 13, and the screw blade 15 is arranged in a spiral structure to enable the materials to be discharged slowly. A plurality of convex blocks 16 distributed in an annular array are fixed in the middle of the circumferential side of the movable sleeve 13. A plurality of chutes 17 distributed in an annular array are opened on the inner wall of the middle part of the discharge hopper 11. The convex blocks 16 are located in the chutes 17, and both the upper and lower ends of the convex blocks 16 are connected to the inner wall of the chutes 17 through the first springs 18. The cooperation between the convex blocks 16 and the chutes 17 plays a guiding role to keep the movable sleeve 13 moving vertically up and down. The first springs 18 play a buffering and vibrating role to prevent material blockage and at the same time play a protective role for the materials.

[0032] The vibrating member 2 is arranged at the bottom of the discharge hopper 11 and is used to drive the discharge port 3 to vibrate and discharge materials. The vibrating member 2 includes extension plates 21 fixed on both sides of the lower surface of the discharge hopper 11. A vibrating motor 22 is fixed in the middle of the outer side of the extension plates 21. The output end of the vibrating motor 22 is connected to a connecting plate 23. The connecting plate 23 is located inside the extension plates 21. One side of the connecting plate 23 is connected to the extension plates 21 through a telescopic rod 24. The arrangement of the telescopic rod 24 enables the connecting plate 23 to move horizontally and at the same time improves the connection strength between the connecting plate 23 and the extension plates 21. Bolts 25 are arranged at both ends of one side of the connecting plate 23.

[0033] The discharge port 3, the top of the discharge port 3 is communicated with the material guiding port 12, and both sides of the top of the discharge port 3 are connected with the vibrating member 2, which is used to slowly discharge the material from the color sorter. Two vibrating motors 22 cooperate to drive the discharge port 3 to vibrate.

[0034] The second implementation manner, the main difference from the first implementation manner is that: mounting holes 31 are opened on both sides of the top end of the discharge port 3, the mounting holes 31 are adapted to the bolts 25, a convex plate 32 is fixed to the top of the discharge end of the discharge port 3, a magnetic attraction plate 32 is attached to the top of the discharge end of the discharge port 3, a matching groove 33 is opened in the middle of the magnetic attraction plate 32, the matching groove 33 is adapted to the convex plate 32, which plays a role in limiting and prevents the magnetic attraction plate 32 from moving randomly. One end of the magnetic attraction plate 32 is fixed with an inclined baffle plate 34, and the baffle plate 34 plays a role in blocking the material to prevent the material from splashing.

The elastic sealing belt 37 is arranged to play a role in sealing to prevent the material from falling below the buffer plate 35.

[0035] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0036] During use, first, the material passes through the screening of the color sorter and falls into the discharge hopper 11. The movable sleeve 13 in the discharge hopper 11 contacts the material through the auger blade 15. The material falls from the material guiding port 12 into the discharge port 3 along the auger blade 15. When the auger blade 15 contacts the material, it moves downward under the impact, so that the movable sleeve 13 drives the convex block 16 to move in the chute 17, causing the first spring 18 to deform and be stressed, producing an effect of buffering and unloading force, and at the same time achieving a certain vibration effect to avoid material blockage. At the same time, two vibrating motors 22 are started. The vibrating motors 22 drive the discharge port 3 to vibrate through the connecting plate 23, and at the same time drive the discharge hopper 11 to vibrate slightly. The material in the discharge port 3 falls to the elastic sealing belt 37 on the buffer plate 35. The buffer plate 35 is stressed to drive the second spring 36 to compress, playing a role in buffering and unloading force to avoid damage to the material. When the flow rate of the material at the outlet of the discharge port 3 is too fast, the magnetic attraction plate 32 is installed at the discharge port 3, and the baffle plate 34 thereon plays a role in blocking the material to prevent the material from splashing.
