Description

[Technical Field]

[0001] This invention relates to a grading and screening machine for shallots, particularly a grading and screening machine for shallots that is used for grading and screening shallots by size. [Previous Technology]

[0002] Shallots are an economic crop commonly used in daily food seasoning. In order to extend the storage time of shallots after harvesting, the roots and stems of shallots are removed. Traditionally, the removal of the roots and stems of shallots is mainly done manually, which not only takes a long time, but is also difficult to implement due to the shortage of agricultural manpower.

[0003] Therefore, there is now a root cutting device for cutting off the roots and stems of shallots. The root cutting device can guide and position the shallots, and cut the two ends of the shallots through the blades that are equidistantly arranged inside the root cutting device, thereby cutting off the roots and stems of the shallots.

[0004] However, each shallot can be roughly divided into two types: long and thin and short and round. Furthermore, the blades of the root cutting machine are set at equal intervals. Therefore, when the root cutting machine is used to cut the roots of shallots, it cannot be fully applied to both types of shallots. If the harvested shallots are directly fed into the root cutting machine for root cutting, it is easy to cause some shallots to be incompletely cut or over-cut.

[0005] Therefore, current root cutting machines cannot handle shallots of different sizes. How to effectively and quickly classify and screen shallots by size to facilitate the use of root cutting machines for cutting the root cutting of shallots of corresponding sizes and reduce the waste rate is the goal that the applicant of this invention is committed to researching. [Summary of the Invention]

[0006] The main purpose of this invention is to provide a shallot grading and sorting machine, which is intended to perform size grading and sorting of shallots, so as to facilitate the use of root cutting equipment to cut the root of shallots of corresponding sizes and reduce the loss rate.

[0007] To achieve the aforementioned objective, the shallot grading and screening machine of this invention includes: a machine body, which includes a feeding section, a first screening section and a second screening section connected sequentially from front to back, the first screening section forming a first collection space and the second screening section forming a second collection space; a lifting drive module, which is disposed in the feeding section of the machine body; A screening module includes a rotation drive, a rotation shaft, a roller, and a feed hopper. The rotation drive is pivotally mounted on the second screening section of the machine body. The rotation shaft connects the rotation drive and is connected to a lifting drive module. The roller is mounted on the rotation shaft and can be rotated by the rotation drive. A rolling space is formed inside the roller, and the rolling space has an inlet near the feed section of the machine body and an outlet near the second screening section. A plurality of screening holes extending axially and in the shape of elongated strips are distributed on the outer peripheral wall of the roller. The plurality of screening holes are located above the first screening section of the machine body. The feed hopper is located at the front end of the roller of the screening module and has a feed channel facing the feed inlet of the roller. The roller of the screening module can be driven by the lifting drive module to change its tilt angle. A control module is mounted on the machine body and electrically connected to the lifting drive module and the screening module.

[0008] The shallot grading and screening machine includes a material collection module, which is set in the feeding part of the machine body and located above the feeding hopper of the screening module.

The lifting carrier is vertically and vertically disposed on the lifting drive component. The rotation shaft of the screening module is connected to the lifting carrier. The lifting drive component can control the lifting of the lifting carrier to adjust the tilt angle of the roller of the screening module.

[0011] In addition, the first screening section of the machine body has a first guide ramp that is inclined downward to one side, and the first screening section has a first screening outlet that communicates with the first collection space on the downward inclined side of the first guide ramp. The second screening section of the machine body has a second guide ramp that is inclined downward in the rear direction, and the second screening section has a second screening outlet that communicates with the second collection space at the rear end of the second guide ramp.

[0012] The shallot grading and screening machine of this invention is used to perform size grading and screening of shallots. The shallot grading and screening machine can control the tilt angle of the roller through the lifting drive module and drive the roller to rotate through the rotation drive component. Then, the shallots to be screened are fed into the feed hopper, so that the shallots enter the feed port of the roller from the feed channel of the feed hopper and roll inside the roller. The shallot grading and screening machine of this invention can adjust the tilt angle of the roller through the lifting drive module and drive the roller to rotate through the rotation drive component. At the same time, it cooperates with the screening holes on the outer wall of the roller to screen the size of the shallots, so that the shallots can be screened according to their size, which is beneficial to the subsequent root and stem cutting operation.
