Abstract
Description
Technical Field
[0001] This utility model relates to the field of sorting equipment, and in particular to a bean sorting machine. Background Technology
[0002] Before processing beans, the raw materials need to be sorted to separate beans of different sizes. The conventional method is to use multiple layers of sieves with different mesh sizes, which is quite cumbersome. Existing technology also includes sorting equipment that uses an inclined conveyor belt to transport beans upwards at an angle and sets up multiple guide plates to guide beans of different grades to different discharge hoppers based on their different weights. However, when feeding beans, there is a lack of buffering as the beans fall from the feed hopper. Different beans may fall out of the same discharge hopper before moving upwards with the conveyor belt, resulting in poor sorting effect. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a bean sorting machine that provides a buffer for the fed beans, resulting in better sorting performance.
[0004] The technical solution of this utility model is as follows:
[0005] A bean sorting machine, characterized in that it includes a casing, a conveyor belt, and sorting baffles. The conveyor belt is inclinedly disposed inside the casing. The side walls of the casing are respectively provided with a first discharge hopper and a second discharge hopper at both ends of the conveyor belt. The top of the casing is provided with a feed hopper at the lower end of the conveyor belt. An inclined plate is provided between the bottom of the feed hopper and the conveyor belt. The inclined plate is inclined in the opposite direction to the conveyor belt. The lower end of the inclined plate is located close to the lower end of the conveyor belt. A feed port is provided in the middle. The feed position of the feed hopper is located on both sides of the feed port.
[0006] The sorting baffles comprise three sets, each set consisting of two baffles: a first baffle, a second baffle, and a third baffle. The bottom sides of the first and second baffles are fitted against the surface of the conveyor belt. The first baffles are positioned on both sides of the material inlet along the conveying direction of the conveyor belt. The second baffles extend from the inner wall of the housing to the middle of the conveyor belt along the inclined conveying direction, with the distance between the two second baffles on one side corresponding to the middle of the conveyor belt being less than the distance between the two first baffles. The third baffles are positioned near the conveyor belt output side, extending from the inner wall of the housing to the middle of the conveyor belt along the inclined conveying direction, and the two third baffles are connected, with a material passage gap between their bottoms and the conveyor belt. A third discharge hopper is located on the side wall of the housing corresponding to the lower end of the inclined baffle, and a fourth discharge hopper is located on the side wall of the housing corresponding to the area between the second and third baffles.
[0007] In a further technical solution, a partition is provided in the middle of the inner side of the feed hopper, and the two sides of the partition and the bottom opening of the feed hopper form feed inlets on both sides of the inclined plate feed inlet.
[0008] In a further technical solution, the conveyor belt is set at an angle of 5-15 degrees relative to the horizontal plane.
[0009] In a further technical solution, the conveyor belt is made of coarse canvas material.
[0010] In a further technical solution, the third discharge hopper is provided with a detachable movable baffle at one end near the machine casing.
[0011] In a further technical solution, a strip-shaped insertion port for matching a movable baffle is provided on the side of the third discharge port near the machine housing, and the movable baffle is inserted through the strip-shaped insertion port.
[0012] In a further technical solution, a fan is provided at the bottom of the inclined plate, and the fan's airflow direction is towards the material inlet.
[0013] The beneficial effects of this utility model are:
[0014] 1. Bean raw materials can enter from the feed hopper to both sides of the feed inlet. The inclined plate provides a buffer, allowing the beans to concentrate on the conveyor belt corresponding to the lower end of the inclined plate, preventing them from falling directly due to lack of buffer. Larger beans can remain in place. The primary beans remaining in place can be discharged from the third discharge hopper. The remaining beans can be separated by the second and third baffles. The second baffle guides the beans to the front between the two first baffles. Secondary beans can roll down between the first baffles under gravity and fall from the first discharge hopper through the feed inlet of the inclined plate. The remaining beans and some impurities are passed through the two second baffles. Tertiary beans can be blocked by the third baffle and roll back between the second and third baffles under gravity, and be discharged from the fourth discharge hopper. The remaining smaller beans that do not meet production requirements and some impurities can pass through the gap between the third baffle and the conveyor belt, and finally be discharged from the second discharge hopper. This sorting machine can provide a buffer for the fed beans, resulting in better sorting effect.
[0015] 2. The third discharge hopper is easy to open and close, preventing some unsuitable beans from being discharged prematurely;
[0016] 3. Install a fan to provide the power for some of the smaller beans to continue moving forward, thereby improving the sorting accuracy. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0024] Example:
[0025] like Figures 1-4 As shown, a bean sorting machine includes a housing 10, a conveyor belt 20, and a sorting baffle. The conveyor belt 20 is inclined inside the housing 10. Support legs 11 are provided around the bottom of the housing 10. A first discharge hopper 12 and a second discharge hopper 13 are respectively provided on the side wall of the housing 10 corresponding to the lower end and the higher end of the conveyor belt 20. A feed hopper 30 is provided on the top of the housing 10 corresponding to the lower end of the conveyor belt 20. An inclined plate 40 is provided between the bottom of the feed hopper 30 and the conveyor belt 20. The inclined plate 40 is inclined in the opposite direction to the conveyor belt 20. The lower end of the inclined plate 40 is located close to the lower end of the conveyor belt 20. A feed port 41 is provided in the middle. A partition 31 is provided in the middle of the inner side of the feed hopper 30. The two sides of the partition 31 and the bottom opening of the feed hopper 30 form feed ports that align with the feed ports 41 on both sides of the inclined plate 40. Only one feed hopper 30 is needed to ensure that the feed position of the feed hopper 30 is on both sides of the feed port 41.
[0026] The sorting baffles consist of three sets, each set comprising two baffles: a first baffle 51, a second baffle 52, and a third baffle 53. The bottom sides of the first baffle 51 and the second baffle 52 are fitted against the surface of the conveyor belt 20, ensuring stable obstruction of the bean raw material while the first baffle 51 and the second baffle 52 move relative to the conveyor belt 20. The first baffle 51 is positioned on both sides of the feed inlet 41 along the conveying direction of the conveyor belt 20, and a connecting plate (not shown in the figure) can be installed between the first baffle 51 and the inner wall of the casing 10. The second baffle 52 extends obliquely from the inner wall of the casing 10 to the middle of the conveyor belt 20. The conveyor belt 20 extends in the conveying direction, and the distance between the two second baffles 52 corresponding to one side of the middle of the conveyor belt 20 is less than the distance between the two first baffles 51; the third baffle 53 is located on the side close to the output of the conveyor belt 20, and extends from the inner side wall of the housing 10 to the middle of the conveyor belt 20 along the conveying direction of the inclined conveyor belt 20, and the two third baffles 53 are connected, with a material passage gap left between the bottom and the conveyor belt 20; the housing 10 is provided with a third discharge hopper 14 on the side wall corresponding to the lower end of the inclined plate 40, and a fourth discharge hopper 15 is provided on the side wall corresponding to the second baffle 52 and the third baffle 53.
[0027] The working principle of the above technical solution is as follows:
[0028] The raw beans can enter from the feed hopper 30 to both sides of the feed inlet 41. The inclined plate 40 provides a buffer, and the raw beans can be concentrated on the conveyor belt 20 corresponding to the lower end of the inclined plate 40, preventing the raw beans from falling directly due to lack of buffer. Larger beans can remain in place. The primary beans that remain in place can be discharged from the third discharge hopper 14. The conveyor belt 20 can drive the raw beans to move obliquely upward. The surface of the conveyor belt 20 itself has a certain curve after bearing the weight. The angle of inclination gradually increases from the lower end to the higher end. The higher the end, the easier it is for the beans to roll down. Therefore, when the beans move obliquely upward with the conveyor belt 20, they will make a curved movement due to the obstruction and guidance of the second baffle 52 and the third baffle 53. After the primary beans are discharged, The remaining beans can be separated by the second baffle 52 and the third baffle 53 respectively. The second baffle 52 can guide the beans to the front between the two first baffles 51. The secondary beans can roll down between the first baffles 51 by gravity and fall out of the first discharge hopper 12 through the feed port 41 of the inclined plate 40. The remaining beans and some impurities carried by them pass through the two second baffles 52. The tertiary beans can be blocked by the third baffle 53 and roll back between the second baffle 52 and the third baffle 53 by gravity and be discharged from the fourth discharge hopper 15. The remaining beans that are too small to meet the production requirements and some impurities carried by them can pass through the gap between the third baffle 53 and the conveyor belt 20 and finally be discharged from the second discharge hopper 13.
[0029] In another embodiment, the conveyor belt 20 can be set at an angle of 5-15 degrees relative to the horizontal plane, depending on the actual raw bean material. This facilitates the rolling back of the raw bean material during stable upward oblique transport.
[0030] In another embodiment, the conveyor belt 20 may be made of a coarse canvas material. The rough surface makes it easier for the conveyor belt 20 to move the bean raw materials.
[0031] In another embodiment, such as Figure 2 As shown, a strip-shaped inlet is provided on the side of the third discharge port near the end of the housing 10, and a movable baffle 16 is inserted through the strip-shaped inlet. Since the third discharge hopper 14 is close to the conveyor belt 20 corresponding to the inclined plate 40, beans are prone to leaking out. The movable baffle 16 is set to prevent beans from jumping out of the third discharge hopper 14 when the bean raw materials are fed. The movable baffle 16 can be removed after the bean raw materials are separated to open the third discharge hopper 14 for discharge.
[0032] In another embodiment, such as Figure 1 As shown, a fan 60 is installed at the bottom of the inclined plate 40, and the airflow of the fan 60 is directed towards the feed inlet 41. The fan 60 is installed to provide the power for some of the smaller beans to continue moving forward, thereby improving the sorting accuracy.
[0033] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
