Description

Technical Field

[0001] This utility model relates to the field of vegetable sorting technology, and in particular to a vegetable sorting and grading device. Background Technology

[0002] In modern agricultural production and agricultural product processing, vegetable selection and grading are crucial for ensuring vegetable quality and market value. As people's living standards continue to improve, their demands for vegetable quality and appearance are becoming increasingly stringent. High-quality, uniformly sized, and undamaged vegetables are not only more favored by consumers but also fetch higher prices in the market, thereby increasing the economic benefits for farmers and related enterprises.

[0003] Existing technology discloses a multi-stage sorting device for dehydrated vegetables, application number 202420370661.2, relating to the field of dehydrated vegetable sorting technology. It includes a support frame, with multiple mounting plates equidistantly fixed to the inner walls of both sides of the support frame. Telescopic rods are fixedly connected to the tops of the mounting plates, and springs are fitted onto the outer surfaces of the telescopic rods. The telescopic rods are divided into three groups, and mounting frames are fixedly connected between the tops of the three groups of telescopic rods. In this invention, the springs, telescopic rods, vibration motor, mounting plates, and mounting frames work together to drive the first, second, and third screening screens to vibrate. This allows for automatic multi-stage sorting of dehydrated vegetables through the first, second, and third screening screens, and, with the assistance of a collection frame, the collection of substandard dehydrated vegetables. This detailed classification and grading of the dehydrated vegetables improves sorting efficiency. However, existing technologies still suffer from limitations such as fixed sieve aperture specifications, making it difficult to quickly adapt to different vegetable size requirements, resulting in low grading efficiency and poor accuracy; the angle of the sorting trough cannot be flexibly adjusted, and the movement speed of vegetables within the trough is uncontrollable, affecting the screening effect and efficiency. Therefore, we propose a vegetable sorting and grading device to solve these problems. Utility Model Content

[0004] To address the shortcomings mentioned above, this utility model provides a vegetable sorting and grading device that enables rapid and precise adjustment of the sieve hole specifications in the sieve plate device through a linkage structure of a rotary adjustment knob and a threaded rod, meeting the grading size requirements of different vegetables; and flexibly adjusts the angle of the sorting trough by means of a lifting cylinder and a hinge structure, thereby controlling the movement speed of vegetables in the trough and optimizing the sorting effect and efficiency.

[0005] To solve the above problems, the technical solution provided by this utility model is as follows:

[0006] A vegetable sorting and grading device includes a base plate, an adjustment plate, a sorting trough, a sieve plate device, and a feed hopper. A support rod is fixedly installed on the upper left end of the base plate, and the upper end of the support rod is hinged to the adjustment plate.

The adjustment plate is fixedly installed on the right end of the adjustment plate. The sieve plate device includes a fixed sieve plate and an adjusting plate. The fixed sieve plate is provided with screening holes and slots, and the adjusting plate is inserted into the slots.

[0007] Furthermore, the sorting troughs are divided into multiple groups from bottom to top. A vibration motor is installed in the middle of the lower end of the bottommost sorting trough. A spring component is installed between two adjacent sorting troughs. A support block is fixedly installed on the upper end of the mounting adjustment plate. A spring component is fixedly installed between the support block and the bottommost sorting trough. A sorting outlet is opened at the left end of the sorting trough.

[0008] Furthermore, the adjusting plate includes a fixed connecting part and an adjusting rod, and the adjusting rod has an adjusting groove, which corresponds to the screening hole.

[0009] Furthermore, a cleaning nozzle is provided at the upper end of the sorting tank at the upper left, and the cleaning nozzle is connected to an external water source through a connecting water pipe.

A rotary adjustment knob is fixedly installed on the right end of the threaded rod, and an adjustment block is fixed on the front right end of the fixed connection part. The fixed adjustment block is threadedly connected to the threaded rod.

[0011] Furthermore, a material distribution rotor is provided at the discharge port of the feed hopper, and multiple material distribution blades are evenly distributed on the material distribution rotor. The material distribution rotor is driven to rotate by a motor.

[0012] Furthermore, both spring component one and spring component two are made of stainless steel, and both spring component one and spring component two are coated with an anti-corrosion coating.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. Flexible sieve hole adjustment: Rotating the adjustment knob links the threaded rod, which drives the adjustment plate to change the sieve hole specifications, adapting to different vegetable grading needs and improving efficiency and accuracy.

[0015] 2. Intelligent Angle Control: The lifting cylinder, combined with the hinge structure, flexibly adjusts the inclination of the sorting slot, precisely controls the movement speed of vegetables, and optimizes the sorting effect.

[0016] 3. Integrated and durable: The material feeding rotor provides uniform feeding, and the cleaning and screening are synchronized. The vibration is combined with the anti-corrosion spring, making it fully functional and durable, reducing maintenance costs.

[0017] In summary, this vegetable sorting and grading equipment has wide applicability, addressing the problems mentioned in the background section where existing technologies still suffer from fixed sieve aperture specifications, making it difficult to quickly adapt to different vegetable size requirements, resulting in low grading efficiency and poor accuracy; and the sorting trough angle cannot be flexibly adjusted, leading to uncontrollable vegetable movement speed within the trough, which affects the sorting effect and efficiency.
