[0002] Goji berries, as a traditional Chinese medicine and health food, have extremely high nutritional and medicinal value, and their market demand is growing. With the continuous development of the goji berry industry, higher requirements have been placed on the impurity screening and separation process in goji berry processing.

[0003] In existing technologies, the main problems with screening and separating impurities in wolfberries are as follows:

[0004] First, the existing screening equipment is still insufficient in terms of screening effect. Although the filter screen can separate smaller impurities, it cannot screen larger but lighter impurities such as leaves. Moreover, after the goji berries enter the screening box, they tend to accumulate, making it impossible to separate the impurities in the middle.

[0005] Secondly, the speed at which goji berries enter the screening box cannot be controlled. If there are many impurities in the goji berries and the goji berries enter the screening box at a fast speed, the impurities in the goji berries will not be cleaned properly. Utility Model Content

[0006] This utility model relates to a high-efficiency goji berry impurity screening and separation device, which solves the problem that existing screening devices still have shortcomings in screening effect and cannot control the speed at which goji berries enter the screening box. If there are many impurities in the goji berries and the speed at which the goji berries enter the screening box is fast, the impurities in the goji berries will not be cleaned.

[0007] This utility model provides a high-efficiency wolfberry impurity screening and separation device, specifically including: a screening box;

[0008] The screening box is fixedly equipped with four wheels on its lower end face, and a feed inlet is provided on the right side of the upper end face of the screening box. A discharge plate is installed below the left side plate of the screening box.

[0009] A partition is fixedly installed inside the screening box, and the lower end of the partition is divided into an inclined structure.

[0010] A pad is fixedly installed on the lower end face of the right side plate of the screening box, and two transverse sliding grooves are provided on the upper end face of the pad.

[0011] A filter plate is installed at an angle inside the screening box. The surface of the filter plate is provided with filter holes. The filter plate is located below the partition.

[0012] The placement plate is provided in two sets, and the surface of the placement plate is provided with through holes. The placement plate is located on the upper end face of the pad.

[0013] A support column, the lower end of which is rotatably connected to the placement plate, and a device groove is provided on the surface of the support column;

[0014] The guide plate is rotatably connected to the right side plate of the screening box, and the front end of the guide plate has a conical structure.

[0015] The connecting rod has its upper end face rotatably connected to the guide plate, and its lower end face is slidably engaged in the device groove inside the support column.

[0016] Furthermore, three sets of brushes are evenly installed on the lower end face of the partition, and two sets of suction pipes are also installed on the surface of the partition. The lower end of the suction pipe has an umbrella-shaped structure, and the upper end of the suction pipe passes through the top plate of the screening box.

[0017] Furthermore, a door panel is rotatably connected to the lower end face of the front side plate of the screening box, and a handle is installed on the outer end face of the door panel.

[0018] Furthermore, a second fastening block is slidably mounted in the transverse groove at the upper end of the pad, and a second screw is fixedly installed on the upper end face of the second fastening block. The upper end of the second screw is engaged in the through hole on the surface of the placement plate, and a nut is connected to the surface of the second screw.

[0021] This invention provides a high-efficiency equipment for screening and separating impurities in wolfberries, which has the following beneficial effects:

[0022] In this utility model:

[0023] 1. It can perform multi-stage screening of goji berries. First, the air suction pipe on the surface of the partition is connected to an external fan and uses its umbrella-shaped structure at the bottom to expand the air suction range, sucking out light impurities such as leaves from the screening box. At the same time, the filter plate separates goji berries from fine impurities through the filter holes on its surface. This multi-stage screening method can comprehensively and effectively remove various impurities from goji berries and improve the purity of goji berries.

[0024] 2. Improve filtration efficiency: The brush on the lower end of the baffle plate not only slows down the sliding speed of goji berries on the filter plate surface, allowing them more time to pass through the filter holes and thus improve the filtration effect, but also prevents goji berries from accumulating on the filter plate, allowing them to spread evenly on the filter plate surface, increasing the filtration area and further improving filtration efficiency.

[0025] 3. The equipment can adjust the tilt angle of the guide plate according to the amount of impurities in the goji berries. When there are few impurities, increasing the angle between the guide plate and the horizontal plane increases the speed at which the goji berries enter the screening box, accelerating the screening efficiency. When there are many impurities, decreasing the angle between the guide plate and the horizontal plane slows down the speed at which the goji berries enter the screening box, allowing for a more thorough screening process and ensuring that impurities are effectively separated. This adjustable design improves the equipment's adaptability to goji berries of different qualities and ensures the stability of the screening effect.

[0026] 4. Through the cooperation of the transverse sliding groove on the pad, the second fastening block, the second screw, and the placement plate, the worker can easily move the placement plate left and right. Simultaneously, by utilizing the vertical sliding groove on the outer end face of the connecting rod, the first fastening block, the first screw, and the device holes on the surface of the support column, the tilt angle of the guide plate can be easily adjusted, and the relative position can be fixed by tightening the nut. This adjustment method is simple and easy to understand; operators can quickly master it and adjust it according to actual conditions. Attached Figure Description

The first screw 901 is engaged in the device hole 602 on the surface of the support column 6. After tightening the nut on the surface of the first screw 901, the relative position of the connecting rod 8 and the support column 6 can be fixed.

[0054] The working principle of this embodiment is as follows: Four wheels 103 are installed on the lower end face of the screening box 1, which can be easily moved to a suitable working position. The guide plate 7 is rotatably connected to the right side plate of the screening box 1, and the guide plate 7 is set in an inclined structure. The worker can place the goji berries on the guide plate 7. Under the action of its own gravity, the goji berries will slide into the feed inlet 101 and enter the screening box 1. After the goji berries enter the filter plate 4 inside the screening box 1, the surface of the filter plate 4 has filter holes 401. Impurities smaller than the filter holes 401 will fall through the filter holes 401, while the goji berries continue to slide down the inclined surface of the filter plate 4, realizing the separation of goji berries from fine impurities. Three sets of brushes 201 are evenly installed on the lower end face of plate 2. On the one hand, this slows down the sliding speed of goji berries on the surface of filter plate 4, improving the filtration effect. On the other hand, it prevents goji berries from accumulating on filter plate 4, ensuring that the goji berries are spread evenly on the surface of filter plate 4. Two sets of suction pipes 202 installed on the surface of partition plate 2 can be connected to an external fan. The lower end of the suction pipe 202 has an umbrella-shaped structure to expand the suction range, allowing light impurities such as leaves to be sucked out of the screening box 1, achieving the separation of goji berries from light impurities. When screening goji berries of different qualities, the tilt angle of guide plate 7 can be adjusted according to the amount of impurities in the goji berries. When there are fewer impurities in the goji berries... When there are many impurities in the goji berries, the angle between the guide plate 7 and the horizontal plane can be increased to improve the speed at which the goji berries enter the screening box 1. When there are many impurities in the goji berries, the angle between the guide plate 7 and the horizontal plane can be decreased to slow down the speed at which the goji berries enter the screening box 1. Specifically, a second fastening block 10 is slidably installed in the transverse groove 301 at the upper end of the pad 3. The second screw 1001 on the second fastening block 10 is engaged in the through hole 501 on the surface of the placement plate 5 and fixed by a nut. The worker can move the position of the second fastening block 10 and the placement plate 5 left and right. The upper end face of the connecting rod 8 is rotatably connected to the guide plate 7, and the lower end face of the connecting rod 8 is slidably installed inside the support column 6. In the device slot 601, by adjusting the position of the first fastening block 9 in the vertical sliding groove 801 on the outer end face of the connecting rod 8, the tilt angle of the guide plate 7 can be adjusted. The first screw 901 is engaged in the device hole 602 on the surface of the support column 6. After tightening the nut on the surface of the first screw 901, the relative position of the connecting rod 8 and the support column 6 can be fixed. The lower end face of the front side plate of the screening box 1 is rotatably connected to the door plate 104. When it is necessary to clean the impurities accumulated inside the screening box 1, the door plate 104 can be opened by pulling the handle on the outer end face of the door plate 104 to clean the impurities inside. The screened goji berries will be discharged from the discharge plate 102 on the left end of the screening box 1.
