[0004] During this layered screening process, blueberries fall from the upper screening mesh belt to the lower conveyor belt. Since the upper screening mesh belt is in motion, it will transport the blueberries from one side to the other. The blueberries start to fall from the input side of the upper screening mesh. The blueberries are likely to accumulate on the end of the lower conveyor belt corresponding to the input side of the upper screening mesh belt, resulting in uneven distribution of blueberries on the lower conveyor belt, and even the blueberries are crushed due to excessive accumulation. Utility Model Content

[0005] The purpose of the utility model is to provide a blueberry screening and guiding structure to solve the problem in the prior art that when blueberries are screened in layers, blueberries fall from the upper screening mesh belt to the lower conveyor belt and easily accumulate on one side of the conveyor belt, resulting in uneven distribution of blueberries.

[0006] In order to achieve the above-mentioned object, the utility model provides a blueberry screening and guiding structure, comprising a fruit screening assembly, wherein the fruit screening assembly is provided with a screening mesh belt, and the screening mesh belt can move along a first direction; a conveying assembly, wherein the conveying assembly is provided with a conveyor belt, and the conveyor belt is used to receive the blueberries screened by the screening mesh belt; the conveyor belt can move along a second direction; the fruit screening assembly is equipped with a material guiding assembly, and the material guiding assembly is located between the screening mesh belt and the conveyor belt; the material guiding assembly includes a material guiding plate, and the material guiding plate is arranged to be inclined in the first direction so that the material guiding plate generates a slope descending toward the conveyor belt; the material guiding plate is arranged close to the input side of the screening mesh belt.

[0007] Furthermore, the material guide assembly includes a material guide rod, which is arranged across the width direction of the screening mesh belt, and the material guide plate is connected to the material guide rod; the length direction of the material guide rod intersects with the first direction.

[0008] Furthermore, the included angle between the length direction of the guide rod and the first direction is α, and the included angle is 0°<α<180°.

[0009] Furthermore, the length of the material guide plate is smaller than the width of the screening belt.

[0010] Furthermore, the length of the guide plate does not exceed half of the width of the screening belt.

[0017] The present invention provides a blueberry screening and guiding structure. A guide plate is disposed between a screening mesh belt and a conveyor belt. The guide plate is tilted in a first direction, forming a downward slope toward the conveyor belt. As the blueberries move along the screening mesh belt from the blueberry input side in the first direction, they fall from the screening mesh belt. As the guide plate approaches the input side of the screening mesh belt, some of the blueberries fall onto the guide plate. The slope of the guide plate causes some of the blueberries to flow toward the side of the conveyor belt away from the input side of the screening mesh belt, reducing accumulation of blueberries on the conveyor belt below the input side of the screening mesh belt. This ensures even distribution of the blueberries on the conveyor belt, preventing them from being crushed due to accumulation.

[0026] The present invention will be described in detail below with reference to the accompanying drawings. What is described here is merely a preferred embodiment of the present invention, and those skilled in the art may conceive of other methods for implementing the present invention based on the preferred embodiment, and such other methods also fall within the scope of the present invention.

[0027] Example

[0028] Please refer to Figures 1-4This embodiment provides a blueberry screening and guiding structure, including a fruit screening assembly 100, wherein the fruit screening assembly 100 is provided with a screening mesh belt 110, which is movable in a first direction; a conveying assembly 200, wherein the conveying assembly 200 is provided with a conveyor belt 210, which is used to receive blueberries screened by the screening mesh belt 110; the conveyor belt 210 is movable in a second direction; the fruit screening assembly 100 is equipped with a guiding assembly 300, which is located between the screening mesh belt 110 and the conveyor belt 210; the guiding assembly 300 includes a guiding plate 310, which is inclined in the first direction so that the guiding plate 310 has a downward slope toward the conveyor belt 210, and is located near the input side of the screening mesh belt 110. The blueberries move along the screening mesh belt 110 from the blueberry input side in a first direction. During the movement, the blueberries fall from the screening mesh belt 110, and some of the blueberries fall onto the guide plate 310. The slope of the guide plate 310 causes some of the blueberries to flow to the side of the conveyor belt 210 away from the input side of the screening mesh belt 110, thereby reducing the accumulation of blueberries on the conveyor belt 210 below the input side of the screening mesh belt 110, so that the blueberries are evenly distributed on the conveyor belt 210, and preventing the blueberries from being crushed due to accumulation.

[0029] It should be noted that in this embodiment, the fruit screening assembly 100 is located above the conveyor assembly 200, and the screening mesh belt 110 is also located above the conveyor belt 210. The slope of the guide plate 310 indicates that one side of the guide plate 310 is closer to the screening mesh belt 110 and the other side is closer to the conveyor belt 210. The guide plate 310 as a whole presents a downward slope toward the conveyor belt 210. The fruit screening assembly 100 and the conveyor assembly 200 each include a motor and a drive shaft assembly. Each motor drives the drive shaft to rotate, thereby driving the screening mesh belt 110 and the conveyor belt 210, respectively. The connection between the motors, drive shafts, screening mesh belt 110, and conveyor belt 210 is well understood by those skilled in the art and will not be further described here.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the guide assembly 300 includes a guide rod 320, which is arranged across the width of the screening belt 110. A guide plate 310 is connected to the guide rod 320. The length of the guide plate 310 coincides with the length of the guide rod 320, and the guide plate 310 and the guide rod 320 remain fixed. The length of the guide rod 320 intersects the first direction. Therefore, when the screening belt 110 moves in the first direction, the blueberries are more likely to fall onto the guide plate 310 and slide to the other side of the conveyor belt 210. This ensures that the blueberries are evenly distributed on the conveyor belt 210, preventing the blueberries from accumulating on one side of the conveyor belt 210 and being crushed.

[0031] Furthermore, Figure 2As shown, the angle between the length direction of the guide rod 320 and the first direction is α, and the angle 0°<α<180°. Among them, the more preferred angle range of angle α is 70°~110°, including 70°, 80°, 100° and 110°. It should be noted that no matter which angle α is selected, the guide plate 310 is arranged close to the input side of the screening mesh belt 110. In other words, when the blueberries start to move along the first direction from the input side of the screening mesh belt 110, the closer the guide plate 310 is to the input side of the screening mesh belt 110, the earlier the blueberries can fall on the guide plate 310 and be guided to other positions by the guide plate 310, which can further reduce the accumulation of blueberries on the side of the conveyor belt 210 close to the input side of the screening mesh belt 110.

[0032] In some embodiments of the present application, Figure 2 As shown, the length of the guide plate 310 is less than the width of the screening belt 110. Preferably, the length of the guide plate 310 does not exceed half the width of the screening belt 110, and most preferably, the length of the guide plate 310 is half the width of the screening belt 110. In this case, approximately half of the blueberries on the screening belt 110 will fall through the guide plate 310 and be directed to the other side of the conveyor belt 210, while approximately half of the blueberries will fall directly onto the conveyor belt 210. This ensures a more even distribution of the blueberries on the conveyor belt 210 and prevents excessive concentration on one side.

[0033] In some embodiments of this application, please refer to Figure 2 The fruit screening assembly 100 includes two sets of side support arms 120, which are arranged on either side of the width of the screening mesh belt 110. The support arms 120 are arranged with multiple mounting positions along a first direction, and the ends of the guide rods 320 are mounted in these mounting positions. The ends of the guide rods 320 can be mounted in different mounting positions on the two side support arms 120, allowing the guide rods 320 to be tilted at different angles relative to the first direction, thereby achieving different degrees of diversion for the blueberries and improving the uniformity of the blueberry distribution on the conveyor belt 210.

[0034] In some embodiments of the present application, Figure 1 and Figure 4 As shown, the fruit screening assembly 100 is further provided with a plurality of filter curtains 400. These filter curtains 400 are arranged across the screening belt 110 and are spaced apart in the first direction. Here, two filter curtains 400 are used as an example. These filter curtains 400 block and distribute the blueberries as they pass over the screening belt 110, ensuring that the blueberries are evenly distributed across the screening belt 110. This allows the full utilization of the screening mesh, improving both blueberry screening efficiency and the uniformity of their fall.

[0035] More specifically, Figure 4As shown, the filter curtain 400 includes a curtain rod 410 and flexible filter strips 420. The curtain rods 410 are mounted on the support arms 120 on either side. The curtain rods 410 are connected to the support arms 120 via bolts and other connectors, making it easy to remove and adjust the curtain rod 410 on the support arms 120. The bottom ends of the flexible filter strips 420 contact the surface of the screening belt 110, blocking the blueberries and ensuring even distribution. The flexible filter strips 420 can be made of rubber, which is flexible enough to avoid scratching the surface of the blueberries.

[0036] Finally, it should be noted that, in one embodiment of the present application, the first direction is perpendicular to the second direction, so that multiple layers of the fruit screening assembly 100 and the conveying assembly 200 can be conveniently arranged to screen blueberries of various specifications and grades to meet different market consumption needs.
