A sorting and grading machine for large cherry picking

Abstract

This utility model discloses a sorting and grading machine for cherry picking, relating to the field of cherry sorting technology. It includes a frame with a rotatable sorting frame mounted on top. A fixed shaft is fixedly connected within the frame, and the sorting frame has a through hole adapted to the fixed shaft. The fixed shaft is inserted into the through hole, and a drive assembly for driving the sorting frame to rotate is fixedly installed inside the frame. This utility model, by setting a rotatable sorting frame on the frame, allows the drive assembly to rotate the sorting frame around the fixed shaft during use, thus creating a certain tilt angle to facilitate the cherries' descent. During the descent, the cherries are graded by multiple sieve plates with different mesh sizes. The reciprocating motion of the drive assembly drives the reciprocating motion of the sorting frame, resulting in a high degree of automation and high sorting efficiency.

Description

Technical Field

[0001] This utility model relates to the field of cherry sorting technology, specifically a sorting and grading machine for picking large cherries. Background Technology

[0002] Selecting and packaging cherries is a tedious and time-consuming process. Generally, the larger cherries with better color are packaged as first-class products, the slightly smaller cherries with better color are packaged as second-class products, and the smallest cherries are packaged as second-class products.

[0003] Traditional sorting methods involve manual selection using sorting tools, which is inefficient, time-consuming, and labor-intensive. Furthermore, manual sorting inevitably results in inconsistent fruit sizes and significant errors. While automated sorting equipment using vibration is currently available, the collisions between fruits during the process easily cause damage, leading to substantial losses. This not only necessitates subsequent sorting, impacting sorting and packaging efficiency but also negatively affecting economic returns. A utility model patent with Chinese patent authorization announcement number CN221869235U discloses a cherry and plum fruit sorting and grading device. This device uses water to fill the sorting box, and then a water pump draws water to impact an impeller, causing it to move. A spraying component sprays water onto a screening component. The impeller's movement causes a vibrating component to move synchronously, thus vibrating the screening component and achieving vibration-based sorting and grading of the fruit. This replaces existing drive equipment, optimizes the device structure, and the water sprayed by the spraying component increases the resistance to the fruit being lifted off the screening component. Furthermore, the water cushions the falling fruit, further reducing the probability of collision damage, avoiding subsequent sorting difficulties, and ensuring economic benefits. However, research on existing technology and the aforementioned patent reveals that the sorting device still has problems with improving sorting efficiency and protecting the fruit from falling during collection. Therefore, this utility model proposes a sorting and grading machine for large cherry picking. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sorting and grading machine for picking cherries.

By setting a rotatable sorting frame on the frame, the drive assembly can drive the sorting frame to rotate around the fixed shaft as the center during use, thereby enabling the sorting frame to generate a certain tilt angle, facilitating the cherries to slide down. During the cherries' slide down, the cherries can be graded by multiple sieve plates with different sieve holes arranged in a row. The reciprocating motion of the drive assembly drives the sorting frame to reciprocate, resulting in a high degree of automation and high sorting efficiency.

[0009] Preferably, the connecting bolt passes through the two through holes and is threaded into the inside of the connecting hole, and the screen plate is fixed to the sorting frame by the connecting bolt.

[0010] Preferably, a feeding frame is provided below the sorting frame. The feeding frame includes a frame body, and a buffer net is provided at the opening of the frame body. The buffer net has a feeding port. By providing a feeding frame below the sorting frame, the buffer net in the feeding frame can buffer the falling fruit during use, avoiding excessive impact from falling fruit and causing damage.

[0012] Preferably, the sorting frame has multiple grooves, and the corresponding number of sieve plates is also several.

[0013] Preferably, the sieve plates are arranged sequentially according to the size of the sieve holes. Beneficial effects

[0014] Compared with existing technologies, this cherry picking sorting and grading machine has the following advantages:

[0015] I. This utility model features a rotatable sorting frame mounted on a frame. During use, a drive assembly can rotate the sorting frame around a fixed axis, allowing it to tilt at a certain angle to facilitate the cherries' descent. As the cherries slide down, they are graded using multiple sieve plates with different mesh sizes. The reciprocating motion of the drive assembly drives the sorting frame to reciprocate, resulting in a high degree of automation and efficiency in the sorting process.

[0016] Second, this utility model sets a feeding frame below the sorting frame. When in use, the buffer net in the feeding frame can buffer the falling fruit and avoid damage to the fruit due to excessive impact.
