Description

Technical Field

[0001] This utility model relates to the field of blueberry screening technology, specifically to a blueberry screening device. Background Technology

[0002] Blueberries are perennial shrubs belonging to the genus Vaccinium in the family Ericaceae. The fruits are blue or bluish-purple, nearly round, and covered with a white bloom. The flesh is delicate, sweet and sour, and rich in anthocyanins, vitamin C, vitamin K, dietary fiber, and potassium and manganese minerals. They have a variety of health benefits, including antioxidant properties, boosting immunity, protecting eyesight, and improving gut function. Blueberries can be eaten fresh or used to make jams, dried fruits, juices, and baked goods. They are widely cultivated globally, mainly in cool, sunny regions such as North America, Europe, and parts of northeastern and southwestern China.

[0003] Blueberry sorting devices are mechanized screening equipment designed specifically for the characteristics of blueberries. They are primarily used for grading blueberries by size and quality. The device includes a feeding mechanism, screening components, a transmission system, and a discharge unit. It separates blueberries of different diameters using technologies such as screen aperture differences or photoelectric sensing, while simultaneously removing rotten fruit and impurities. Its working principle is largely based on gravity falling or mechanical vibration causing the blueberries to move on the screen surface, achieving grading and sorting. It is characterized by high efficiency, precision, and reduced labor costs, improving the efficiency of blueberry commercial processing and ensuring uniform fruit quality. It is suitable for blueberry processing. The initial processing stage after harvesting helps standardize production in the blueberry industry. During use, in high humidity environments, the surface moisture of blueberries makes it easier for impurities to stick to the screen or cause the fruit skin to soften, increasing the risk of damage. In existing technologies, an airflow drying device is set up before screening to blow away free water on the surface of blueberries with low-temperature drying airflow, reducing the adhesion of moisture to the screen. However, some large particles of impurities, such as branches, leaves, soil, stones, and metal fragments, which have not been removed by pre-screening, will directly enter the main screen. These impurities are easily stuck in the screen holes, causing blueberries to accumulate and significantly reducing the screening speed. Utility Model Content

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, this invention illustrates a blueberry screening device according to one embodiment, comprising a body 1, a screening mechanism 2 mounted on the rear side of the body 1 for preliminary screening, and a cleaning mechanism 3 mounted on the front side of the body 1 for cleaning the body 1. The screening mechanism 2 includes a motor 201, which is located at the left rear end of the body 1. A turntable 202 is fixedly connected to the output end of the motor 201, and the kinetic energy of the motor 201 drives the turntable 202 to rotate. A rotating mechanism is fixedly connected to the top of the turntable 202. A connecting rod 204 is rotatably connected to the outer side of the rotating rod 203. A screen 205 is fixedly connected to the other end of the connecting rod 204. A spring 206 is fixedly connected to the right side of the outer wall of the screen 205, which plays a role in compression and rebound. The spring 206 is fixedly connected to the inner side of the machine body 1. A bearing plate 4 is fixedly connected to the left side of the outer wall of the machine body 1. The top of the bearing plate 4 is fixedly connected to the bottom of the motor 201. A sliding groove 5 is opened on the rear side of the top of the machine body 1.

[0025] In some examples, after the motor 201 starts, it drives the turntable 202 fixed to its output end to rotate. The rotating rod 203 on the upper part of the turntable 202 then performs a circular motion. The connecting rod 204 on the outside of the rotating rod 203 converts the circular motion into a reciprocating linear motion, which in turn pushes the screen 205 connected to the other end of the connecting rod 204 to perform a reciprocating motion. During the movement of the screen 205, the spring 206 fixed on the right side undergoes continuous compression and extension. Through the compression and rebound characteristics of the spring 206, the shaking effect of the screen 205 is enhanced, so that the material on the screen 205 can be screened and separated under the shaking action, which is convenient for subsequent processing. The outer wall of the machine body 1 is provided with a support plate 4 on the left side. The top of the support plate 4 is fixedly connected to the bottom of the motor 201.

A rotating rod 302 is fixedly connected to the output end of the second motor 301. The rotating rod 302 is driven to rotate by the kinetic energy of the second motor 301. A connecting rope 303 is provided on the outer side of the rotating rod 302. An L-shaped rod 304 is fixedly connected to the other end of the connecting rope 303. A liquid storage tank 305 is provided on the top of the L-shaped rod 304. Multiple nozzles 306 are equidistantly connected to the bottom of the liquid storage tank 305. A cleaning rod 307 is fixedly connected to the bottom of the L-shaped rod 304. A second bearing plate 7 is fixedly connected to the left side of the outer wall of the body 1. The top of the second bearing plate 7 is fixedly connected to the bottom of the second motor 301. A connecting groove 8 is opened on the top left side of the body 1. The inner side of the connecting groove 8 is slidably connected to the bottom of the L-shaped rod 304. In some examples, after the second motor 301 is started, its kinetic energy is transmitted to the rotating rod 302 connected to its output end, causing it to rotate.

Storage boxes 11 are provided at both the front and rear ends of the right side of the machine body 1. Support legs 12 are fixedly connected to the bottom of the storage boxes 11, and the support legs 12 are used to support the storage boxes 11.

[0028] When motor 201 starts, it drives the turntable 202 fixed at the output end to rotate. The rotating rod 203 on the top of the turntable 202 moves in a circular motion with the turntable 202. The connecting rod 204, which is rotatably connected to the outside of the rotating rod 203, converts the circular motion into reciprocating linear motion, which drives the screen 205, which is fixedly connected to the other end of the connecting rod 204, to move in a reciprocating motion. During the movement of the screen 205, the spring 206 fixed on the right side is continuously compressed and stretched. By utilizing the compression and rebound characteristics of the spring 206, the shaking effect of the screen 205 is enhanced, so that the material on the screen 205 can be screened and separated under the shaking action, which is convenient for subsequent processing. When motor 2 301 starts, the kinetic energy of motor 2 301 drives the rotating rod 302 fixed to its output end to rotate. The rotating rod 302 drives the L-shaped rod 304 to reciprocate or rotate through the connecting rope 303 wrapped around its outer side. The liquid storage tank 305 at the top of the L-shaped rod 304 moves synchronously. The cleaning liquid in the tank is continuously sprayed onto the surface of the machine body 1 through the nozzle 306 at the bottom. The cleaning rod 307 at the bottom of the L-shaped rod 304 moves synchronously with the L-shaped rod 304 to scrub the surface of the machine body 1, thereby achieving a thorough cleaning of the machine body 1 after processing.
