Description

Technical Field

[0001] The utility model relates to the technical field of pepper processing, in particular to a pepper separation mechanism with good anti-clogging effect. Background Technique

[0002] During the picking process of peppers, after the pepper fruits are picked, in order to ensure the uniform particle size of the pepper fruits, the pepper fruits need to be screened again, so as to separate the pepper fruits of different sizes, ensure the uniform size of the pepper fruits in the same batch, and facilitate subsequent processing or selling. During the separation process, a corresponding separation mechanism is required. Most of the existing separation mechanisms are vibrating screens.

[0003] In the prior art, when the vibrating screen screens pepper fruits of different sizes, since most of the pepper fruits (such as millet peppers and bird's eye peppers) are cones with a larger end, the pepper fruits are easily inserted into the sieve holes during the screening process and block the sieve holes, resulting in a decrease in the screening efficiency. When many sieve holes are blocked, it will also lead to the phenomenon of ineffective screening (that is, small particle peppers cannot be screened out due to the blockage of the sieve holes during vibration). Generally, it is necessary to stop the machine for manual cleaning, resulting in a lower overall screening efficiency. Therefore, a pepper separation mechanism with good anti-clogging effect is needed. Summary of the Utility Model

[0004] The purpose of this application is to provide a pepper separation mechanism with good anti-clogging effect to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, this application provides the following technical solution: A pepper separation mechanism with good anti-clogging effect, including a separation box, a vibrating screen and a vibrating motor. The vibrating screen is vertically slidably installed in the separation box, and the vibrating motor is fixed to the outer side wall of the separation box and is used to drive the vibrating screen to vibrate up and down;

[0006] A cleaning brush with bristles in contact with the bottom surface of the vibrating screen is arranged below the vibrating screen, and the upper end of the cleaning brush is slidably connected to the vibrating screen through a sliding structure;

[0007] A servo motor is fixed to the side wall of the separation box adjacent to the vibrating motor. The output shaft end of the servo motor is drivingly connected with a reciprocating lead screw. The reciprocating lead screw rotates through the side walls on opposite sides of the separation box, and a reciprocating shaft sleeve adapted to the reciprocating lead screw is arranged on the reciprocating lead screw;

[0008] The cleaning brush and the reciprocating shaft sleeve are variably connected through a follower. When the reciprocating shaft sleeve moves along the reciprocating lead screw, the cleaning brush is driven by the follower to reciprocate and slide along the lower end of the vibrating screen.

[0009] Preferably, the follower includes:

[0010] A fixed sleeve block, which is fixedly sleeved on the reciprocating shaft sleeve, and an upward-opening insertion hole is provided at the upper end of the fixed sleeve block;

[0011] The movable connecting rod has its upper end fixed to the lower end of the cleaning brush, and its lower end is slidably inserted into the jack.

[0012] The limiting structure enables the movable connecting rod not to disengage from the fixed sleeve block when moving up and down.

[0013] Wherein, the movement stroke of the movable connecting rod in the jack is consistent with the movement stroke of the vibrating screen vibrating up and down.

[0014] Preferably, the limiting structure includes:

[0015] The guide groove is a vertical groove and is opened on the inner side wall of the jack;

[0016] The ball is rollingly embedded on the side wall of the lower end of the movable connecting rod, and the end of the ball protruding from the movable connecting rod rolls and abuts in the guide groove.

[0017] Preferably, elastic gaskets are fixed at both the upper and lower ends in the guide groove. The cross-section of the elastic gasket is arc-shaped and is adapted to the spherical surface of the ball.

Discharge ports are opened on the side walls of two adjacent sides of the separation box. One of the discharge ports is located on one side of the lower end of the vibrating screen, and a collection box is slidably placed in the other discharge port.

[0020] In summary, the technical effects and advantages of the present utility model are as follows:

[0021] 1. In the present utility model, through the arrangement of the reciprocating lead screw, the follower and the cleaning brush, after the servo motor is started, it drives the reciprocating lead screw to rotate. When the reciprocating lead screw rotates, it drives the reciprocating bushing to reciprocate axially along the reciprocating lead screw. During this process, the reciprocating bushing drives the cleaning brush to reciprocate along the lower end of the vibrating screen through the follower. And the cleaning brush is variably connected with the reciprocating bushing through the follower.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0030] Embodiment: Refer to Figures 1 - 4A chili separation mechanism with good anti-clogging effect is shown, including a separation box 1, a vibrating screen 2 and a vibrating motor 3. The vibrating screen 2 is vertically slidably installed in the separation box 1. The vibrating motor 3 is fixed to the outer side wall of the separation box 1 and is used to drive the vibrating screen 2 to vibrate up and down. A feeding port 11 is opened at the upper end of the separation box 1, and a guiding block 12 for guiding chili fruits to one side of the separation box 1 is fixed in the feeding port 11. Discharge ports 13 are opened on the side walls of two adjacent sides of the separation box 1 (only one is shown in the figure, and the other is on the side wall adjacent to this one). One of the discharge ports 13 is located on one side of the lower end of the vibrating screen 2, and a collection box 14 is slidably placed in the other discharge port 13. A collection box 14 can also be placed at the discharge port 13 on one side of the lower end of the vibrating screen 2 (not shown in the figure) to collect the screened chili fruits;

[0031] A cleaning brush 4 with bristles pressing against the bottom surface of the vibrating screen 2 is arranged below the vibrating screen 2. The bristles of the cleaning brush 4 are flexible bristles. When the bristles of the cleaning brush 4 coincide with the screen holes of the vibrating screen 2, they can extend into the screen holes of the vibrating screen 2 to push the chili fruits stuck in the screen holes upward, so as to dredge the blocked screen holes of the vibrating screen 2 and achieve the purpose of good anti-clogging. The upper end of the cleaning brush 4 is slidably connected to the vibrating screen 2 through a sliding structure;

[0032] As Figure 3 shown, the sliding structure includes a chute 21 opened at the lower end of the vibrating screen 2 and a T-shaped slider 41 fixed to the upper end of the cleaning brush 4. The T-shaped slider 41 is slidably connected in the chute 21 to provide a stable sliding guide for the cleaning brush 4 and can drive the cleaning brush 4 to vibrate synchronously.

[0033] A servo motor 5 is fixed to the side wall of the separation box 1 adjacent to the vibrating motor 3. The output shaft end of the servo motor 5 is drivingly connected with a reciprocating lead screw 6. The reciprocating lead screw 6 rotates through the side walls on two opposite sides of the separation box 1, and a reciprocating shaft sleeve 61 adapted to the reciprocating lead screw 6 is arranged on the reciprocating lead screw 6;

[0034] The cleaning brush 4 and the reciprocating shaft sleeve 61 are variably connected through a follower 7. When the reciprocating shaft sleeve 61 moves along the reciprocating lead screw 6, the cleaning brush 4 is driven by the follower 7 to reciprocally slide along the lower end of the vibrating screen 2.

[0035] Based on the above structure, after the servo motor 5 is started, it drives the reciprocating lead screw 6 to rotate. When the reciprocating lead screw 6 rotates, it drives the reciprocating shaft sleeve 61 to reciprocally move along the axial direction of the reciprocating lead screw 6. During this process, the reciprocating shaft sleeve 61 drives the cleaning brush 4 to reciprocally slide along the lower end of the vibrating screen 2 through the follower 7. And the cleaning brush 4 is variably connected to the reciprocating shaft sleeve 61 through the follower 7. Therefore, the cleaning brush 4 can closely move along with the vibrating vibrating screen 2, achieving the purpose of cleaning the screen holes of the vibrating screen 2 while vibrating synchronously with the vibrating screen 2, achieving a good anti-clogging effect. Compared with cleaning during shutdown, automatic cleaning can improve the screening efficiency.

[0036] Further, the follower 7 includes a fixed sleeve block 71, a movable connecting rod 72 and a limiting structure;

[0037] The fixed sleeve block 71 is fixedly sleeved on the reciprocating sleeve 61. An upward-opening insertion hole 711 is provided at the upper end of the fixed sleeve block 71. The upper end of the movable connecting rod 72 is fixed to the lower end of the cleaning brush 4, and the lower end of the movable connecting rod 72 is slidably inserted into the insertion hole 711;

[0038] The limiting structure enables the movable connecting rod 72 not to disengage from the fixed sleeve block 71 when moving up and down;

[0039] Among them, the movement stroke of the movable connecting rod 72 in the insertion hole 711 is the same as the movement stroke of the vibrating screen 2 vibrating up and down.

[0040] When the cleaning brush 4 vibrates synchronously with the vibrating screen 2, the movable connecting rod 72 moves up and down synchronously with the cleaning brush 4, so that the movable connecting rod 72 moves up and down in the insertion hole 711 of the fixed sleeve block 71. And the fixed sleeve block 71 reciprocates horizontally with the reciprocating sleeve 61. Therefore, the fixed sleeve block 71 can drive the cleaning brush 4 to reciprocate through the movable connecting rod 72 slidably connected thereto, forming a movement that always fits the vibrating screen 2, avoiding the change of the distance between the vibrating screen 2 and the cleaning brush 4 caused by the vibration of the vibrating screen 2, and thus ensuring the dredging effect.

[0041] Furthermore, the limiting structure includes:

[0042] A guide groove 712, the guide groove 712 is a vertical groove and is opened on the inner side wall of the insertion hole 711;

[0043] A ball 73, the ball 73 is rollingly embedded on the side wall of the lower end of the movable connecting rod 72, and the end of the ball 73 protruding from the movable connecting rod 72 rolls against the inside of the guide groove 712.

[0044] Using the cooperation of the guide groove 712 and the ball 73 can not only limit the movement stroke of the movable connecting rod 72, but also reduce the friction between the movable connecting rod 72 and the fixed sleeve block 71, so that the resistance received by the movable connecting rod 72 during movement is smaller, and it is more convenient to realize the flexible movement of the movable connecting rod 72.

[0045] Furthermore, elastic gaskets 74 are fixed at both the upper and lower ends in the guide groove 712. The elastic gaskets 74 are made of elastic materials commonly used in the prior art and suitable for this embodiment (such as rubber, silicone). The cross-section of the elastic gasket 74 is arc-shaped and is adapted to the spherical surface of the ball 73. Through the setting of the elastic gasket 74, when the ball 73 moves to the upper and lower ends of the guide groove 712, the ball 73 contacts the elastic gasket 74, and the elastic gasket 74 can play a buffering role on the ball 73, avoiding the direct collision of the ball 73 with the inner wall of the guide groove 712, reducing the probability of damage to the guide groove 712 and the ball 73, and thus extending the service life of both.

[0046] In addition, in order to further reduce the wear between the movable connecting rod 72 and the fixed sleeve block 71, in this embodiment, a gap is provided between the side wall of the movable connecting rod 72 and the inner wall of the jack 711, and by controlling the height of the lower end of the guide groove 712, when the movable connecting rod 72 moves to the lowest position, there is also a gap between the lower end of the movable connecting rod 72 and the inner bottom wall of the jack 711, and the size of the gap is 1-6 mm. Thus, the movable connecting rod 72 will not rub against the fixed sleeve block 71 when lifting and lowering with the cleaning brush 4, thereby basically avoiding the wear between the movable connecting rod 72 and the fixed sleeve block 71 and greatly extending the service life of both;

[0047] In addition, when a gap is provided between the side wall of the movable connecting rod 72 and the inner wall of the jack 711, in order to ensure that the fixed sleeve block 71 can stably drive the movable connecting rod 72 to move horizontally, multiple guide grooves 712 and multiple balls 73 can be provided, thereby enhancing the connection stability between the fixed sleeve block 71 and the movable connecting rod 72 and achieving a good transmission effect.

[0048] Working principle of the utility model: During daily use, the staff first turns on the vibration motor 3 and the servo motor 5, so that the vibration motor 3 drives the vibrating screen 2 to vibrate in the vertical direction. Then, the chili fruits to be separated (sieving large and small fruits) are put into the separation box 1 from the feeding port 11. The chili fruits move to one side of the separation box 1 (i.e., the uppermost side of the vibrating screen 2) under the action of the guide block 12 and fall on the vibrating screen 2. The chili fruits are gradually separated into large and small fruits under the sieving action of the vibrating screen 2. The large fruits move along the upper surface of the vibrating screen 2 and fall out from the discharge port 13 on one side, while the small fruits directly fall below the vibrating screen 2, thus completing the sieving of the chili;

[0049] During this process, the servo motor 5 drives the reciprocating shaft sleeve 61 to reciprocate axially along the reciprocating lead screw 6 through the reciprocating lead screw 6. The reciprocating shaft sleeve 61 drives the fixed sleeve block 71 to move synchronously. At this time, the movable connecting rod 72 moves up and down synchronously with the cleaning brush 4, so that the fixed sleeve block 71 can drive the cleaning brush 4 to reciprocate through the movable connecting rod 72 slidably connected thereto. The cleaning brush 4 can move closely along the vibrating vibrating screen 2, avoiding the change of the distance between the vibrating screen 2 and the cleaning brush 4 due to the vibration of the vibrating screen 2, achieving the purpose of cleaning the screen holes of the vibrating screen 2 while vibrating synchronously with the vibrating screen 2, achieving a good anti-blocking effect. Compared with cleaning during shutdown, automatic cleaning can improve the sieving efficiency.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
