[0027] ① On the one hand, multiple screening mesh structures will be set up in the grading equipment to achieve malt screening, but the multiple screening mesh structures are inside the equipment, and there is no door structure on the equipment that can be easily opened, which makes it inconvenient to manually clean the screening mesh structure later;

[0028] ② The second aspect is that the multiple screening nets installed inside the equipment are in a static state and lack a structure that can realize synchronous reciprocating motion of multiple screening nets, resulting in low screening efficiency and easy clogging;

[0029] To do this, see Figure 1-5The utility model provides a grading device for beer malt processing, comprising: a screening and grading box 1, two symmetrically arranged triangular brackets 2 are fixedly connected to the two side walls of the screening and grading box 1, a grading frame a3 is slidably connected to the top opening of the screening and grading box 1, an inclined screening mesh a31 is fixedly connected to the inner wall of the grading frame a3, a discharge port a311 is provided on the left wall of the grading frame a3, a discharge hopper a33 fixed to the bottom end of the grading frame a3 is provided at the bottom of the screening mesh a31, the discharge hopper a33 slides in a movable opening a34 provided on the front side wall of the screening and grading box 1, a grading frame b5 slidably connected to the inner side of the screening and grading box 1 is provided below the discharge hopper a33, and the inner wall of the grading frame b5 is fixedly connected to the inclined screening mesh b51. , a discharge port b511 is provided on the right side wall of the grading frame b5, and a discharge hopper b53 is provided at the bottom of the screening net b51, which is fixed to the bottom end of the grading frame b5. The discharge hopper b53 slides in the movable opening b54 provided on the rear side wall of the screening and grading box 1. A lower hopper a4 fixed to the left inner wall of the screening and grading box 1 is provided between the bottom of the discharge hopper a33 and the top of the grading frame b5. A lower hopper b6 fixed to the inner wall of the screening and grading box 1 is provided at the bottom of the discharge hopper b53. A movable opening c61 for discharging the material from the lower hopper b6 is provided on the left side wall of the screening and grading box 1. A movable door 7 is hinged in the opening provided on the right side wall of the screening and grading box 1, and a locking structure is connected between the outer wall of the movable door 7 and the right side wall of the screening and grading box 1;

[0030] It also includes a reciprocating transmission structure 8, which is installed on the rear side wall of the screening and grading box 1 and is connected to the bottom end of the discharge hopper a33 and the top end of the grading frame b5. The reciprocating transmission structure 8 can realize the synchronous reciprocating left and right movement of the grading frame b5 and the grading frame a3, greatly improving the screening efficiency;

[0031] Among them, the sieve holes of the screening mesh a31 are smaller than the sieve holes of the screening mesh b51, so that the intercepted large-particle malt can be discharged from the discharge port a311 to the lower hopper a4, and fall into the screening mesh b51 in the grading frame b5 for further screening, and the larger-particle malt intercepted again on the screening mesh b51 can fall from the discharge port b511 to the lower hopper b6 and be discharged, and the discharge directions of the discharge hopper a33, the discharge hopper b53 and the lower hopper b6 are all different, which can avoid the mixing of malts of different sizes when discharging.

[0032] Further as Figure 1-5As shown, it is worth mentioning that in order to ensure that the movable door 7 can be fixed to the device when the device is in use, and when the device is not in use, the movable door 7 can be easily opened to facilitate cleaning of the screening mesh a31 and the screening mesh b51, a locking structure is provided, including a connecting block b72 fixed to the right side wall of the screening and grading box 1, and a hand screw 73 is movably inserted on the connecting block b72, one end of the hand screw 73 is threadedly connected to the screw hole provided at one end of the connecting block a71, and the connecting block a71 is fixed to the outer side of the movable door 7.

[0033] Further as Figure 1-5 As shown, it is worth mentioning that the front and rear side walls of the grading frame a3 are fixed with sliding seats a32 with an I-shaped structure in vertical section, and the two sliding seats a32 are respectively slidably connected to the sliding grooves a provided on the front and rear side walls of the screening and grading box 1. The front and rear side walls of the grading frame b5 are fixed with sliding seats b52 with an I-shaped structure in vertical section, and the two sliding seats b52 are respectively slidably connected to the sliding grooves b provided on the front and rear side walls of the screening and grading box 1.

[0034] The sliding seat a32 and the sliding seat b52 are provided to ensure good stability when the grading frame a3 and the grading frame b5 move back and forth left and right.

[0035] Further as Figure 1-5 As shown, it is worth mentioning that in order to enable the grading frame a3 and the grading frame b5 to achieve synchronous reciprocating motion, a reciprocating transmission structure 8 is provided, including a motor 85 fixed to the rear side wall of the screening and grading box 1. The output shaft of the motor 85 extends to the inner side of the screening and grading box 1 and is fixed to a turntable 84. A transmission column 83 is fixed to the edge of the surface of the turntable 84 facing away from the motor 85. A transmission rod 81 is movably sleeved on the outer side of the transmission column 83. A transmission channel 82 cooperating with the transmission column 83 is provided on the transmission rod 81. The two ends of the transmission rod 81 are respectively fixed to the bottom end of the discharge hopper a33 and the top end of the grading frame b5.

[0036] The width of the transmission channel 82 is equal to the diameter of the transmission column 83 , and the length of the transmission channel 82 is greater than the diameter of the turntable 84 .

[0037] In summary: when using the grading device for beer malt processing, the malt material to be screened can be prepared, and the malt material can be poured into the grading frame a3 from the top opening, and by starting the motor 85, the turntable 84 drives the transmission column 83 to rotate, and cooperates with the transmission rod 81 and the transmission channel 82 to make the grading frame a3 and the grading frame b5 move back and forth left and right, so that the incoming malt material can be dynamically screened, thereby greatly improving the screening efficiency, and the malt materials of different sizes after screening can be discharged from three directions respectively, and mixing is not easy to occur. Secondly, when it is necessary to manually clean or wash the screening mesh a31 and the screening mesh b51, the hand screw 73 can be loosened, so that the connecting block a71 is no longer fixed by the hand screw 73, and the movable door 7 can be easily opened, which is convenient for manual cleaning or washing of the screening mesh a31 and the screening mesh b51 in the later stage.
