Abstract
Description
Technical Field
[0001] This utility model relates to the field of grading and screening technology, and in particular to a blueberry fruit grading and screening device. Background Technology
[0002] Blueberries, also known as bilberries, are small berries, round or oval in shape, with a deep blue or purplish-blue exterior. They have a thin, soft skin, delicate and juicy flesh, and a sweet and sour taste. After harvesting, blueberries are sorted by size. The common method is to place the blueberries on a shaking sieve, allowing them to pass through different mesh sizes for grading. However, this process can scratch the blueberries, affecting their later preservation and causing problems for consumers. Utility Model Content
[0003] The purpose of this invention is to provide a blueberry fruit grading and sorting device to solve the above-mentioned problems.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] A blueberry fruit grading and sorting device includes an inclined support mechanism with a sorting mechanism installed on it for grading and sorting the blueberries as they roll downwards. The support mechanism includes a support frame with an inclined frame mounted on it. The sorting mechanism includes guide rods spaced apart on the frame, parallel to the inclination of the frame, with the spacing between the guide rods gradually increasing from the highest point to the lowest point of the frame. A limiting shell is fixed to the upper end of the frame, and a partition is installed on the limiting shell near its highest point. A discharge port is opened at the lower end of the partition. Discharge hoppers are spaced apart on the lower side of the frame, and a cleaning component for cleaning between the guide rods is installed on the upper side of the discharge hoppers below the frame.
[0006] Further configuration: The cleaning component includes a reciprocating screw arranged parallel to the frame. There are two reciprocating screws arranged opposite each other. A transmission component is fixed at one end of the reciprocating screw, and a power source is connected to the other end of one of the reciprocating screws. A support seat is provided on the reciprocating screw, and a cleaning roller is installed through the support seat. Rotating components are provided at both ends of the cleaning roller.
[0007] Further configuration: The rotating assembly includes gears fixed to both ends of the cleaning roller brush, and a rack that meshes with the gears is fixed to the lower end of the frame.
[0008] Further configuration: The reciprocating screw is rotatably connected to the frame, and the reciprocating screw is threadedly connected to the support base.
[0009] Further details: The cleaning roller is rotatably connected to the support base, and the transmission component is a synchronous pulley with a synchronous belt fitted on it.
[0010] Further features: The discharge hopper is fixedly connected to the frame, and the discharge hopper has a slot through which the cleaning roller brush passes.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] By setting up a sorting mechanism on the support structure, the blueberries roll down from the top of the guide rods, and fall from the guide rods in order of size into the corresponding discharge hoppers. At the same time, the cleaning component moves back and forth under the guide rods to move the blueberries between the guide rods and make them fall, thus improving the sorting effect of the blueberries.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figures 1-5 As shown, a blueberry fruit grading and sorting device includes an inclined support mechanism, on which a sorting mechanism is provided to grade and sort the blueberries as they roll downwards.
[0025] In this embodiment, the support mechanism includes a support frame 11, on which an inclined frame 12 is provided; used to support and install the sorting mechanism.
[0026] In this embodiment, the sorting mechanism includes guide rods 21 spaced apart on the frame 12. The guide rods 21 are parallel to the inclined plane of the frame 12. The spacing between the guide rods 21 gradually increases from the highest point to the lowest point of the frame 12. A limiting shell 22 is fixed at the upper end of the frame 12 to limit the blueberries rolling down from the top. A partition 23 is provided at the highest point of the limiting shell 22. A discharge port is opened at the lower end of the partition 23. A discharge hopper 24 is spaced apart on the lower side of the frame 12. A cleaning component for cleaning between the guide rods 21 is installed on the upper side of the discharge hopper 24 below the frame 12.
[0027] The cleaning assembly includes a reciprocating screw 25 parallel to the frame 12. Two reciprocating screws 25 are arranged opposite each other. A transmission component 211 is fixed to one end of the reciprocating screw 25, and a reduction motor 210 is connected to the other end of one of the reciprocating screws 25. A support base 26 is provided on the reciprocating screw 25, and a cleaning roller brush 27 is threaded through the support base 26. Rotating components are provided at both ends of the cleaning roller brush 27. The rotating components include gears 28 fixed to both ends of the cleaning roller brush 27, and a rack 29 meshing with the gears 28 is fixed to the lower end of the frame 12. The reciprocating screw 25 is rotatably connected to the frame 12, and the reciprocating screw 25 is threadedly connected to the support base 26. The cleaning roller brush 27 is rotatably connected to the support base 26. The transmission component 211 is a synchronous pulley, and a synchronous belt is fitted on the transmission component 211. The discharge hopper 24 is fixedly connected to the frame 12, and a slot is opened on the discharge hopper 24 through which the cleaning roller brush 27 passes. The working of the reduction motor 210 drives one of the reciprocating screws 25 to rotate. Through the transmission component 211, the power is transmitted to the other reciprocating screw 25 to achieve synchronous rotation, which moves the support base 26 on the reciprocating screw 25 back and forth. During the movement, the gear 28 and rack 29 on the cleaning roller brush 27 mesh and rotate, so that the cleaning roller brush 27 pushes the fruit between the guide rods 21 to drop the material.
[0028] The working principle and usage process of this utility model are as follows: Blueberries are placed on the upper part of the limiting shell 22. The fruits roll down the guide rods 21 through the feeding port at the lower end of the partition 23. During the rolling process, as the distance between the guide rods 21 gradually increases, the fruits fall from the guide rods 21 into the corresponding discharge hopper 24 and are concentrated. At the same time, the reduction motor 210 drives one of the reciprocating screws 25 to rotate, and the other reciprocating screw 25 rotates synchronously through the transmission component 211. The support seat 26 on the reciprocating screw 25 moves back and forth. During the movement, the gear 28 and rack 29 on the cleaning roller brush 27 mesh and rotate, so that the cleaning roller brush 27 moves the fruits between the guide rods 21 to drop them, ensuring the sorting effect.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
