DETAILED DESCRIPTION

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] The present embodiment provides a bran pretreatment device. The utility model can initially limit the position of the screen 5 by setting a supporting frame 2, so that it is limited to the inner side of the supporting frame 2. By setting a limiting slot 3, the position of the screen 5 can be limited again, thereby preventing the screen 5 from detaching from the inner side of the supporting frame 2. Similarly, through the cooperation between the supporting frame 2 and the limiting mechanism 6, the screen 5 can be quickly limited. When the production demand changes and bran of other sizes needs to be screened, the screen 5 can be quickly replaced, which improves the flexibility of the equipment and optimizes the use efficiency to a certain extent.

[0026] See also Figure 1 to Figure 6 A bran pretreatment device includes a base 1, the upper surface of the base 1 is fixedly connected to a supporting frame 2, and the inner wall of the supporting frame 2 is provided with a layer of buffer rubber pad, which can avoid the violent collision between the screen 5 and the supporting frame 2 when the screen 5 shakes, thereby protecting the screen 5.

[0027] A limited slot 3 is defined inside the support frame 2 .

[0028] A limiting mechanism 6 is provided on the outer side of the supporting frame 2 .

[0029] The limiting mechanism 6 comprises a limiting frame 601 , the outer surface of the limiting frame 601 is fixedly connected to the outer surface of the supporting frame 2 , and the interior of the limiting frame 601 is slidably connected to a limiting rod 602 .

[0030] One end of the limiting rod 602 is fixedly connected to the limiting block 604 , and the limiting block 604 is plugged into the inside of the limiting slot 3 , and the other end of the limiting rod 602 away from the limiting block 604 is fixedly connected to a handle 605 .

[0031] The outer surface of the limiting rod 602 is sleeved with an elastic member 603, which is made of a spring and has elastic and retractable rebound properties. One end of the elastic member 603 is fixedly connected to the outer surface of the limiting block 604, and the end of the elastic member 603 away from the limiting block 604 is fixedly connected to the outer surface of the limiting frame 601.

[0032] Pulling the handle 605 away from the screen 5 can drive the limit rod 602 and the limit block 604 to move accordingly, and then the limit block 604 will enter the limit slot 3. During the movement of the limit block 604, the elastic member 603 will be compressed to cause it to deform and store a certain amount of elastic potential energy, and at the same time, the limit on the screen 5 will be released. At this time, the screen 5 can be moved upward and taken out from the inner side of the carrier 2, and the handle 605 can be released. The compressed elastic member 603 will push the limit block 604 to move in the opposite direction to achieve reset.

[0033] A first fixing ear 4 is fixedly connected to the outer surface of the supporting frame 2 , and a blocking member 7 is arranged on the front side of the supporting frame 2 .

[0034] The blocking member 7 includes a baffle 701, and the outer surface of the baffle 701 slides with the inner wall of the support frame 2, the outer surface of the baffle 701 is fixedly connected to the second fixing ear 702, the interior of the second fixing ear 702 is plugged with a pin 703, and the pin 703 is plugged into the interior of the first fixing ear 4.

[0035] After the screening operation is completed, the latch 703 is moved upward so that the latch 703 is pulled out from the first fixing ear 4 and the second fixing ear 702 to release the fixed limit of the baffle 701.

[0036] A support plate 8 is fixedly connected to the upper surface of the carrier frame 2 .

[0037] A cleaning mechanism 9 is provided in front of the support plate 8 .

[0038] The cleaning mechanism 9 includes a servo motor 901 , the outer surface of the servo motor 901 is fixedly connected to the outer surface of the support plate 8 , the output end of the servo motor 901 is fixedly connected to a reciprocating screw 902 , and the outer surface of the reciprocating screw 902 is rotatably connected to the inner wall of the support plate 8 .

[0039] The outer surface of the reciprocating screw 902 is rotatably connected to the support frame 903, and the outer surface of the support frame 903 is fixedly connected to the outer surface of the support plate 8. The end of the support frame 903 close to the support plate 8 is designed to be relatively wide, which can increase the stability of the entire cleaning mechanism 9. The outer surface of the reciprocating screw 902 is threadedly connected to the limiting slider 904, and the outer surface of the limiting slider 904 is slidably connected to the inner wall of the support frame 903.

[0040] The bottom surface of the limiting slider 904 is fixedly connected with an electric push rod 905 , and the telescopic end of the electric push rod 905 is fixedly connected with a cleaning brush 906 .

[0041] Start the electric push rod 905. At this time, the telescopic end of the electric push rod 905 will drive the cleaning brush 906 to move up and down, and then the cleaning height of the cleaning brush 906 can be adjusted. When the cleaning brush 906 contacts the screen 5 below, the electric push rod 905 can be closed, and then the servo motor 901 is started. At this time, the servo motor 901 can drive the reciprocating screw rod 902 to rotate, and then drive the limiting slider 904 to reciprocate back and forth. At this time, the limiting slider 904 will drive the electric push rod 905 and the cleaning brush 906 to follow the movement, and then the cleaning brush 906 will smooth the bran on the screen 5 to prevent the bran from clumping and affecting the screening efficiency.

[0042] A screen 5 is arranged on the inner side of the carrier frame 2 .

[0043] The screen 5 is placed on the inner side of the support frame 2 and below the limit block 604 , and does not contact the limit block 604 in a static state, so the screen 5 has sufficient space to move when shaking up and down on the support frame 2 .

[0044] A vibration motor 10 is fixedly mounted on the inner wall of the carrier frame 2 .

[0045] The upper surface of the vibration motor 10 is in contact with the bottom surface of the screen 5. When the vibration motor 10 is working, the vibration motor 10 itself will vibrate, thereby driving the screen 5 in contact with it to vibrate up and down, so that the screen 5 can screen the bran.

[0046] Working principle: When the utility model is in use, the bran to be screened can be poured onto the screen 5, and then the vibration motor 10 is turned on. At this time, the vibration motor 10 itself will vibrate, and then it can drive the screen 5 in contact with it to shake up and down, so that the screen 5 can screen the bran, and the screened bran will fall into the inner side of the base 1 for centralized collection, and the electric push rod 905 is started. At this time, the telescopic end of the electric push rod 905 will drive the cleaning brush 906 to move up and down, and then the cleaning height of the cleaning brush 906 can be adjusted, so that the cleaning brush 906 contacts the screen 5 below, the electric push rod 905 can be closed, and then the servo motor 901 is started. At this time, the servo motor 901 can drive the reciprocating screw rod 902 to rotate, and then drive the limiting slider 904 to reciprocate back and forth. At this time, the limiting slider 904 will drive the electric push rod 905 and the cleaning brush 906 to follow the movement, and then the cleaning brush 906 will smooth the bran on the screen 5 to prevent the bran from piling up and affecting the screening efficiency. After completing the screening operation, the latch 703 is moved upward so that the latch 703 is pulled out from the first fixing ear 4 and the second fixing ear 702 to release the fixed limit of the baffle 701, and then the baffle 701 is removed. At this time, the remaining bran on the screen 5 can be cleaned forward again by moving the cleaning brush 906. When production requirements change and bran of other sizes needs to be screened, the screen 5 needs to be replaced. Specifically, pulling the handle 605 away from the screen 5 can drive the limit rod 602 and the limit block 604 to move with it, and then the limit block 604 will enter the limit slot 3. During the movement of the limit block 604, the elastic member 603 will be compressed to cause it to deform and store a certain amount of elastic potential energy, and at the same time, the limit on the screen 5 will be released. At this time, the screen 5 can be moved upward and taken out from the inner side of the carrier 2, and the handle 605 is released. The compressed elastic member 603 will push the limit block 604 to move in the opposite direction to achieve reset. At this time, the limit block 604 will re-enter the carrier The inner side of the rack 2, and then the sieve 5 of other sizes prepared in advance is put back into the inner side of the carrier rack 2. During the downward putting process, the limit block 604 will be squeezed. Since the limit block 604 is designed with an inclined surface, the limit block 604 can be pushed into the limit slot 3. At the same time, the limit block 604 will compress the elastic member 603. When the sieve 5 is completely located below the limit block 604, the compressed elastic member 603 will push the limit block 604 to move to the top of the sieve 5, thereby blocking and limiting the sieve 5 to prevent the sieve 5 from detaching from the inner side of the carrier rack 2, and the sieve 5 can be quickly replaced, which improves the flexibility of the equipment and optimizes the use efficiency to a certain extent.
