[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example: Refer to Figures 1 to 4 The coffee bean roasting device comprises a roasting tank 1 and a shaking roasting assembly. Two diagonal brackets 19 are symmetrically fixedly connected to the bottom of the roasting tank 1. A plurality of heating tubes 2 are fixedly connected inside the roasting tank 1. A feed hopper 3 and a discharge hopper 4 are respectively connected to the upper and lower ends of the roasting tank 1. When in use, the coffee beans to be roasted are introduced into the roasting tank 1 from the feed hopper 3, and the discharge hopper 4 can discharge debris generated during the roasting process.

[0025] The side walls on both sides of the roasting tank 1 are fixedly connected with lower hoppers 5, and an opening and closing assembly is provided between each lower hopper 5 and the roasting tank 1. The opening and closing assembly includes an electric push rod 16 fixedly connected to the side wall of the roasting tank 1, and the driving end of the electric push rod 16 is fixedly connected to a right-angle rod 17, and the end of the right-angle rod 17 away from the electric push rod 16 is fixedly connected to a sealing plate 18, and the sealing plate 18 is slidably arranged in the lower hopper 5. After the roasting is completed, the two electric push rods 16 can be controlled to drive, and the two sealing plates 18 can be controlled to move back to back through the two right-angle rods 17, so that the two lower hoppers 5 can be opened, and then the screen plate 6 is controlled to be in an inclined state, so that the roasted coffee beans can be discharged from the lower hopper 5.

[0026] A sieve plate 6 is rotatably installed in the roasting tank 1, and a plurality of heating tubes 2 are symmetrically arranged on the upper and lower sides of the sieve plate 6, so that both the upper and lower sides of the sieve plate 6 can be heated, which is beneficial to improving the roasting effect of the coffee beans on the sieve plate 6.

[0027] The shaking roasting assembly includes a rotating shaft 7 fixedly passing through the center of the front side of the sieve plate 6, the rotating shaft 7 movably passes through the front wall of the roasting tank 1 and is fixedly connected to a swing frame 8, the front wall of the roasting tank 1 is fixedly connected to a motor 9, the end of the output shaft of the motor 9 is fixedly connected to a crank 10, the front wall of the crank 10 is fixedly connected to a fixed block 20, and the fixed block 20 is movably placed in the swing frame 8. When in use, after the coffee beans are placed on the sieve plate 6, the motor 9 and each heating tube 2 are started, the motor 9 can drive the crank 10 to rotate to make the fixed block 20 move in a circle, and then the fixed block 20 can slide up and down in the swing frame 8 Back and forth, the swing frame 8 can be driven to swing back and forth. At this time, the rotating shaft 7 can be used to drive the sieve plate 6 to swing back and forth in the roasting tank 1, so that the coffee beans can roll back and forth on the sieve plate 6 and are fully and evenly heated, thereby improving the roasting efficiency of the coffee beans.

The plate 11 swings back and forth synchronously. When the arc-shaped tooth plate 11 and the corresponding incomplete gear 12 are meshed, the incomplete gear 12 will be driven to rotate and the spring 15 will be deformed. Then, when the arc-shaped tooth plate 11 is disengaged from the incomplete gear 12, under the deformation force of the spring 15, the incomplete gear 12 will collide with the arc-shaped tooth plate 11, so that the screen plate 6 may vibrate to a certain extent, and the coffee beans rolling back and forth on the screen plate 6 can be shaken, so that the coffee beans and the heat in the roasting tank 1 can be fully contacted, and the roasting effect of the coffee beans is further improved.
