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.

[0022] In practical implementation: such as Figures 1-4 As shown, a multi-stage coffee fruit sorting device for coffee production includes a screening box 1 with two sieve plates 2 slidably connected to its inner wall; a screening mechanism 3, which can efficiently screen coffee fruits and prevent them from clogging, is disposed on the inner wall of the screening box 1; wherein, the screening mechanism 3 includes a rotating shaft 301 rotatably connected to the top of the sieve plate 2, a cleaning plate 302 fixedly connected to one side of the rotating shaft 301, and a pressing plate 303 slidably connected to both sides of the inner wall of the cleaning plate 302; several uniformly distributed compression springs 304 are disposed between the pressing plate 303 and the cleaning plate 302; a first motor 305 is fixedly installed at the bottom of the sieve plate 2; the output shaft of one end of the first motor 305 is fixedly connected to the rotating shaft 301; and a drive assembly 312 is disposed on the inner wall of the screening box 1.

[0023] When cleaning the impurities and coffee berries clogging the sieve plate 2, the first motor 305 drives the cleaning plate 302 to rotate along the sieve plate 2 via the rotating shaft 301. One side of the cleaning plate 302 contacts the impurities and coffee berries through the extrusion groove 309 and squeezes and rotates them. The extrusion plates 303 on both sides of the cleaning plate 302 are tilted to one side and extended to one side through the compression spring 304. As the cleaning plate 302 rotates, it contacts the side of the impurities and coffee berries. The friction generated by the extrusion plates 303 squeezes the impurities and coffee berries out of the sieve plate 2, preventing the impurities and coffee berries from clogging the sieve plate 2 and improving the screening effect of the device.

[0024] like Figure 2 and Figure 3As shown, the screening mechanism 3 further comprises a plurality of sliding blocks 306 evenly distributed and fixedly connected to the top end of the screen plate 2, the sliding blocks 306 are slidingly connected to the inner wall of the screening box 1, spring telescopic rods 307 are fixedly connected between the two ends of the sliding blocks 306 and the inner wall of the screening box 1, a plurality of baffle plates 308 are fixedly connected to the top end of the screen plate 2, a plurality of extrusion grooves 309 are formed on both sides of the cleaning plate 302, a material guide groove 310 is formed on one side of the inner wall of the screening box 1, and the material guide groove 310 is arranged on one side of one of the screen plates 2; a discharge groove 311 is formed on the other side of the inner wall of the screening box 1, and the discharge groove 311 is arranged on one side of the other screen plate 2.

[0025] When the screen plate 2 moves up and down, the screen plate 2 slides up and down in the screening box 1 through the sliding blocks 306 on the outer wall to screen the coffee fruits and impurities, the spring telescopic rods 307 can protect and buffer the sliding blocks 306, the baffle plates 308 can prevent impurities and coffee fruits from falling into the grooves between the sliding blocks 306 and the screening box 1, the coffee fruits after one screening move along the inclined portion of one of the screen plates 2, pass through the material guide groove 310, and fall onto the other screen plate 2 for screening, and the other screen plate 2 discharges unqualified coffee fruits through the discharge groove 311, so that the impurities and coffee fruits can be quickly screened, and the screening effect of the device is improved.

[0026] As shown in Figure 4 The driving assembly 312 comprises two rotating rods 3121 rotatingly connected to the inner wall of the screening box 1, two cams 3122 are fixedly connected to one end of the rotating rod 3121, the rotating rod 3121 is arranged at the bottom end of the screen plate 2, a transmission wheel 3123 is fixedly connected to one end of the rotating rod 3121, a transmission belt 3124 is drivingly connected between the two transmission wheels 3123, one end of one of the rotating rods 3121 is fixedly connected to a second motor 3125, two collecting plates 3126 are slidingly connected to the inner wall of the screening box 1, and the two collecting plates 3126 are arranged below the two screen plates 2, respectively.

[0027] When the second motor 3125 drives one of the rotating rods 3121 to rotate, the rotating rod 3121 is drivingly connected to the other rotating rod 3121 through the two transmission wheels 3123 and the transmission belt 3124 to drive the other rotating rod 3121 to rotate, so that the two rotating rods 3121 can simultaneously extrude the two screen plates 2 to make the screen plates 2 slide up and down to screen the impurities and coffee fruits, one of the collecting plates 3126 can collect the impurities and unqualified coffee fruits filtered from one of the screen plates 2, and the other collecting plate 3126 can collect the qualified coffee fruits screened from the other screen plate 2, so that the device can be driven, and the use effect of the device is improved,

[0028] In use, coffee cherries are placed on one of the sieve plates 2 through the feed inlet at the top of the sieving box 1. A second motor 3125, driven by a controller, rotates one of the rotating rods 3121, simultaneously driving two transmission wheels 3123 connected to a transmission belt 3124 to drive the other rotating rod 3121 to rotate synchronously. The rotating rod 3121 drives a cam 3122 to rotate, pressing against the sieve plate 2. The sieve plate 2 then slides up and down via a slider 306 and a spring telescopic rod 307 to sieve the coffee cherries. One sieve plate 2 can sieve impurities and unqualified coffee cherries. After sieving, the coffee cherries move along the inclined surface of the sieve plate 2, pass through the guide chute 310, and fall into the other sieve plate. The coffee cherries are screened on plate 2. Unqualified coffee cherries are discharged through discharge chute 311. The controller starts the first motor 305 to drive the cleaning plate 302 on one side of the rotating shaft 301 to squeeze and clean the impurities and coffee cherries clogging the screen plate 2. As the cleaning plate 302 rotates, one side of the extrusion plate 303 comes into contact with the side of the impurities and coffee cherries. Through the large friction coefficient of the extrusion plate 303 and the cooperation of the compression spring 304, the impurities and coffee cherries are contacted and rubbed, squeezing them out of the screen plate 2 and preventing the screen plate 2 from clogging. One collection plate 3126 can collect impurities and unqualified coffee cherries, and the other collection plate 3126 can collect qualified coffee cherries.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
