Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a grading and screening device for bamboo shoots. Background Technology

[0002] Fresh bamboo shoots are a type of food made from high-quality fresh bamboo shoots. They retain the crisp, tender, fresh, and refreshing taste of fresh bamboo shoots and are rich in nutrients such as protein, fiber, calcium, phosphorus, iron, and vitamins. They help with digestion and prevent constipation. During the production and processing of fresh bamboo shoots, they need to be screened using screening equipment.

[0003] For example, Chinese patent document CN215313962U discloses a bamboo shoot size sorting device, including a base, a conveyor belt mounted on a first support column of the base; a sorting frame inclined towards the ground connected to the end of the conveyor belt; rotating rollers perpendicular to the conveyor belt's direction of transport arranged parallel to the sorting frame; the vertical distance between the rotating rollers gradually increases from the end near the conveyor belt to the end far from the conveyor belt, thus dividing the area into ≥2 sorting zones; a speed-reducing cylinder is located below each sorting zone, and a removable bamboo shoot box is located below the speed-reducing cylinder. This utility model device has a good bamboo shoot size grading effect, high production efficiency, low labor intensity, simple operation, and does not affect the quality of bamboo shoots.

[0004] During the use of the bamboo shoot size screening device, if too many bamboo shoots are put in, the device may not be able to effectively screen the bamboo shoots, which will affect the screening accuracy. If too few bamboo shoots are put in, the screening efficiency will be affected. Utility Model Content

A hopper is fixedly installed on the inner wall of the casing. The device also includes a conveying component installed at the bottom of the hopper, which is used to uniformly convey the bamboo shoots to the top of the screening plates. A shaking component is installed on the front side of the rectangular frame, and a transmission structure is provided between the shaking component and the conveying component. Through the conveying component and the transmission structure, the shaking component is used to drive the rectangular frame and screening plates to reciprocate back and forth.

[0007] Preferably, the conveying assembly includes a motor, a drive roller, a driven roller, and a conveyor belt. The motor is fixedly installed on one side of the outer wall of the machine housing. The drive roller and the driven roller are rotatably installed on both sides of the machine housing. The conveyor belt is sleeved on the drive roller and the driven roller. The output shaft of the motor is fixedly installed at one end of the drive roller. This assembly can evenly convey the bamboo shoots to the screening plate, avoiding screening omissions or misjudgments caused by material accumulation in traditional equipment. At the same time, there is no need to control the amount of bamboo shoots fed, ensuring screening efficiency.

[0008] Preferably, the swaying assembly includes a fixed shaft plate, an eccentric shaft, and a connecting rod. There are two fixed shaft plates, both of which are fixedly installed on the front outer wall of the chassis. The eccentric shaft is rotatably installed on the two fixed shaft plates, and the connecting rod is rotatably installed on the outer wall of the eccentric shaft.

[0009] Preferably, the transmission structure includes a first synchronous pulley, a second synchronous pulley, and a synchronous belt. The first synchronous pulley is fixedly installed on the outer wall of the drive roller, the second synchronous pulley is fixedly installed on the outer wall of the eccentric shaft, and the synchronous belt is sleeved on the first and second synchronous pulleys. The synchronous belt meshes with both the first and second synchronous pulleys. When the conveying component is running, it can synchronously drive the shaking component, causing the rectangular frame and the inclined screening plate to move back and forth. This allows the bamboo shoots to move downwards on the screening plate with the inclination angle, while also being fully tumbled due to the reciprocating shaking, enabling precise grading based on the gap between the screening plates and improving grading accuracy.

[0010] Preferably, the front side of the chassis has a material box opening, and four collection boxes are provided inside the material box opening, with the collection boxes extending into the interior of the chassis.

[0012] Preferably, two guide rods are fixedly installed on the front and rear inner walls of the chassis, and the front and rear sides of the rectangular frame are slidably installed on the guide rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This bamboo shoot grading and screening equipment uses a conveying assembly consisting of a hopper, motor, drive roller, driven roller, and conveyor belt to evenly transport bamboo shoots to the screening plate. This avoids the screening omissions or misjudgments caused by material accumulation in traditional equipment. At the same time, there is no need to control the amount of bamboo shoots fed, ensuring screening efficiency. Through the transmission structure, the shaking assembly can be driven synchronously when the conveying assembly is running, so that the rectangular frame and the inclined screening plate move back and forth. This allows the bamboo shoots to move downwards on the screening plate with the tilt angle, while also being fully tumbled due to the reciprocating shaking. This allows for precise grading based on the gap between the screening plates, improving grading accuracy. Attached Figure Description

The conveyor belt 11 is fitted onto the drive roller 9 and the driven roller 10. The output shaft of the motor 8 is fixedly installed at one end of the drive roller 9. When the motor 8 is started, the output shaft of the motor 8 drives the drive roller 9 and the first synchronous pulley 12 to rotate. The rotation of the drive roller 9 drives the conveyor belt 11 to rotate, so that the conveyor belt 11 can evenly convey the bamboo shoots to the top of the screening plate 3, avoiding screening omissions or misjudgments caused by material accumulation in traditional equipment. At the same time, there is no need to control the amount of bamboo shoots fed, ensuring screening efficiency.

[0019] Furthermore, the rocking assembly includes a fixed shaft plate 4, an eccentric shaft 5, and a connecting rod 6. There are two fixed shaft plates 4, both of which are fixedly installed on the front outer wall of the housing 1. The eccentric shaft 5 is rotatably installed on the two fixed shaft plates 4, and the connecting rod 6 is rotatably installed on the outer wall of the eccentric shaft 5.

[0020] Furthermore, the transmission structure includes a first synchronous pulley 12, a second synchronous pulley 13, and a synchronous belt 14. The first synchronous pulley 12 is fixedly installed on the outer wall of the drive roller 9, and the second synchronous pulley 13 is fixedly installed on the outer wall of the eccentric shaft 5. The synchronous belt 14 is sleeved on the first synchronous pulley 12 and the second synchronous pulley 13, and the synchronous belt 14 meshes with both the first synchronous pulley 12 and the second synchronous pulley 13. When the motor 8 is started, the output shaft of the motor 8 drives the drive roller 9 and the first synchronous pulley 12 to rotate. The first synchronous pulley 12 can drive the second synchronous pulley 13 and the eccentric shaft 5 to rotate through the synchronous belt 14. The eccentric shaft 5 can drive the rectangular frame 2 and the screening plate 3 to reciprocate back and forth through the connecting rod 6, so that the bamboo shoots falling on the screening plate 3 roll back and forth on the top of the screening plate 3. Since the rectangular frame 2 and the screening plate 3 are inclined, the bamboo shoots will move downward while rolling. Finally, the bamboo shoots fall into different collection boxes 15 according to the gap between the two screening plates 3, thereby screening the bamboo shoots and improving the grading accuracy.

[0021] Furthermore, a material box opening is provided on the front side of the chassis 1, and four collection boxes 15 are provided inside the material box opening, with the collection boxes 15 extending into the interior of the chassis 1.

[0024] Working principle: Bamboo shoots are fed into the hopper 7 inside the machine housing 1. The bamboo shoots fall through the hopper 7 onto the top of the driven roller 10. The motor 8 is started, and the output shaft of the motor 8 drives the drive roller 9 and the first synchronous wheel 12 to rotate. The rotation of the drive roller 9 drives the conveyor belt 11 to rotate, so that the conveyor belt 11 can evenly transport the bamboo shoots to the top of the screening plate 3. The first synchronous wheel 12 drives the second synchronous wheel 13 and the eccentric shaft 5 to rotate through the synchronous belt 14. The eccentric shaft 5 drives the rectangular frame 2 and the screening plate 3 to reciprocate back and forth through the connecting rod 6, so that the bamboo shoots falling on the screening plate 3 roll back and forth on the top of the screening plate 3. Since the rectangular frame 2 and the screening plate 3 are set at an inclination, the bamboo shoots will move downwards while rolling. Finally, the bamboo shoots fall into different collection boxes 15 according to the gap between the two screening plates 3, thus achieving screening of the bamboo shoots.
