Technical Field

[0001] The utility model relates to the technical field of blueberry screening equipment, in particular to a self-cleaning blueberry machine. Background Art

[0002] From being picked in the orchard to being sold on the market, blueberries undergo a series of processes, including washing and screening. Washing removes dust, bacteria, branches, and other debris, while screening allows for grading by size to meet diverse consumer needs.

[0003] During the screening process of blueberries, blueberries of different sizes are screened through a mesh belt. During a series of screening processes, fruits are easily trapped between the mesh belt and the feeder belt, and manual cleaning of the trapped part is very difficult and dangerous. For example, in the prior art, a Chinese patent document with publication number CN109127349A discloses a filterable conveying device for blueberry production, which is provided with two layers of mesh belts. The mesh belts are made of soft fabric and can reduce the collision and damage caused by blueberries during transportation. The device is provided with a brush, which contacts the surface of the blueberries during the blueberry transportation process and cleans the blueberries. However, the brushes in the prior art are mainly used to clean blueberries, and it is difficult to clean the part between the mesh belt and the feeder belt where the fruits are trapped.

[0025] 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.

[0026] Example

[0027] Please refer to Figure 1-Figure 4 This embodiment provides a self-cleaning blueberry machine, including a fruit screening device 100, which includes a mesh belt 110, a feeder belt 120 and a driving shaft 130. The mesh belt 110 and the feeder belt 120 rotate synchronously through the driving shaft 130, thereby achieving the effect of pushing up the material. Specifically, the mesh belt 110 and the feeder belt 120 share a driving shaft 130, the feeder belt 120 is wound around the driving shaft 130, and the mesh belt 110 is wound around the outside of the feeder belt 120. The feeder belt 120 is relatively short in length and is arranged on the side close to the driving shaft 130. When the blueberries fall on the mesh belt 110, some of the blueberries may be in a half-fallen state in the holes of the mesh belt 110. The operation of the feeder belt 120 can push up the blueberries in the holes of the mesh belt 110 to prevent the mesh belt 110 from rotating and squeezing the blueberries. A brush roller 150 is provided between the mesh belt 110 and the feeder belt 120. The movement paths of the mesh belt 110 and the feeder belt 120 are located on both radial sides of the brush roller 150, respectively. The brush roller 150 comes into contact with both the mesh belt 110 and the feeder belt 120. The movement paths of the mesh belt 110 and the feeder belt 120 are located on both radial sides of the brush roller 150, respectively. The movement of the mesh belt 110 and the feeder belt 120 allows all positions of the mesh belt 110 and the feeder belt 120 to come into contact with the brush roller 150. The rotation of the brush roller 150 can clean all positions of the mesh belt 110 and the feeder belt 120. It can be confirmed that the positions of the mesh belt 110 and the feeder belt 120 where the fruit is clamped are also cleaned by the brush roller 150 as they move, thus ensuring the hygiene and safety of the blueberry transportation process, improving production efficiency, and enhancing the competitiveness of the blueberry machine.

[0028] It should be noted that both the mesh belt 110 and the feeder belt 120 are belt structures. The mesh holes in the mesh belt 110 are circular, with the diameter of the holes determined based on the size of the blueberries. The mesh holes on the same mesh belt 110 have a consistent diameter. The mesh belt 110 has different diameters on different fruit screening devices 100 to screen blueberries of different sizes.

[0029] Furthermore, Figure 2 and Figure 3 As shown, the fruit screening device 100 further includes a main support roller 140. When viewed axially, the main support roller 140 and the brush roller 150 are axially parallel and staggered with each other, with the main support roller 140 positioned to the side and below the brush roller 150. The mesh belt 110 passes through the main support roller 140 and is positioned on one side of the brush roller 150. The main support roller 140 lifts the mesh belt 110 toward the brush roller 150, making it easier for the mesh belt 110 to contact the brush roller 150, thereby improving the cleaning efficiency of the brush roller 150.

[0030] It is understandable that the brush roller 150 needs external force to rotate, so the brush roller 150 is connected to a driving mechanism, and the driving mechanism is also divided into multiple types, for example, the brush roller 150 can be driven by electricity or manually. In one embodiment of the present application, Figure 1 As shown, the brush roller 150 is manually driven and is connected to a crank 151 . Shaking the crank 151 causes the brush roller 150 to rotate.

[0031] In some embodiments of this application, please refer to Figure 2 and Figure 3 , further comprising a flushing device 160, which flushes water toward the brush roller 150. The flushing device 160 includes a clean water pipe, which can be a flexible pipe or a corrugated pipe, and the water outlet position of the clean water pipe can be easily adjusted, so that the flushing device 160 can flush different positions of the brush roller 150 to improve cleanliness.

[0032] In some embodiments of the present application, Figure 1 and Figure 4As shown, the fruit screening device 100 is equipped with several filter curtains 170. These filter curtains 170 are positioned across the mesh belt 110, perpendicular to the direction of movement of the mesh belt 110. As the blueberries move through the filter curtains 170 along with the mesh belt 110, the filter curtains 170 evenly distribute the blueberries on the mesh belt 110, thereby improving the efficiency of the mesh belt 110 in screening the blueberries. Specifically, the filter curtains 170 include a curtain frame 171, which is equipped with several flexible filter strips 172. The ends of the flexible filter strips 172 contact the mesh belt 110. The curtain frame 171 is positioned across the mesh belt 110. The flexible filter strips 172 are made of a relatively soft material to prevent damage to the blueberry surface. The flexible filter strips 172 can be made of rubber.

[0033] Further, such as Figure 2 As shown, the fruit screening device 100 also includes a belt support device 180, which includes a belt support cylinder 181 and a belt support roller 182. The two ends of the mesh belt 110 are respectively connected to the driving shaft 130 and the driven shaft. The mesh belt 110 forms a closed structure through the belt support roller 182. The closed structure presents a triangular structure, and the belt support roller 182 is located at the vertex of the triangle. The belt support roller 182 is connected to one end of the belt support cylinder 181. The belt support cylinder 181 is extended and retracted to tighten or relax the closed structure of the mesh belt 110. The contraction of the belt support cylinder 181 relaxes the closed structure of the mesh belt 110, making it convenient for the mesh belt 110 to be removed from the fruit screening device 100 for replacement.

[0034] It is understandable that if Figure 1 As shown, the blueberry machine also includes a fruit collecting device 200, which is disposed below the fruit screening device 100 and is used to collect the fruit sieved by the fruit screening device 100. Specifically, the fruit collecting device 200 includes a fruit collecting conveyor belt 210, which moves perpendicular to the direction of movement of the mesh belt 110. Blueberries fall from the mesh belt 110 onto the fruit collecting conveyor belt 210 and are transported from the fruit collecting conveyor belt 210 to a corresponding collection location.
