Embodiment 1

[0032]Embodiment 1: After the device is powered on, the variable-speed motor starts to work at 4000 rpm, and a material platform is installed at one end of the frame. The onions enter the conveyor belt in a single row through gravity, and the transmission speed is 0.2 m / s. After the image signal is captured by the CCD It is sent to the CPU processing center for processing to ensure the acquisition of a full range of onion images. After computer software calculations, the push action of the hydraulic cylinder is notified, and the appearance and size information of each onion is classified into four levels. : Defective products (surface damage, onion diameter less than 6 cm), grade Ⅰ (diameter > 15 cm), grade Ⅱ (10-15 cm), grade Ⅲ (6-10 cm), of which 4 hydraulic cylinders are processed separately After receiving the signal, each onion is pushed to the recycling box of the designated level, that is, the onion sorting is completed, and the sorting efficiency is 1200 kg / h.

Embodiment 2

[0033] Embodiment 2: After the device is energized, the variable-speed motor starts to work at 5000 rpm, and a material table is installed at one end of the frame, and the onions enter the conveyor belt in a single row through gravity, and the transmission speed is 0.25m / s, and the image signal is captured by the CCD It is sent to the CPU processing center for processing to ensure the acquisition of a full range of onion images. After computer software calculations, the push action of the hydraulic cylinder is notified, and the appearance and size information of each onion is classified into four levels. : Defective products (surface damage, onion diameter 15 cm), grade II (10-15 cm), grade III (6-10 cm), of which 4 hydraulic cylinders are processed separately After receiving the signal, each onion is pushed to the recycling bin of the designated level, and the onion sorting is completed. Onion sorting efficiency is 1500 kg / h.

Embodiment 3

[0034] Embodiment 3: After the device is powered on, the variable-speed motor starts to work at 6000 rpm, and a material table is installed at one end of the frame. The onions enter the conveyor belt in a single row through gravity, and the transmission speed is 0.3 m / s. After the image signal is captured by the CCD It is sent to the CPU processing center for processing to ensure the acquisition of a full range of onion images. After computer software calculations, the push action of the hydraulic cylinder is notified, and the appearance and size information of each onion is classified into four levels. : Defective products (surface damage, onion diameter 15 cm), grade II (10-15 cm), grade III (6-10 cm), of which 4 hydraulic cylinders are respectively processed After receiving the signal, each onion is pushed to the recycling bin of the designated level, and the onion sorting is completed. Onion sorting efficiency is 1800 kg / h.

Abstract

The invention discloses an intelligent onion sorting device which comprises a conveyor belt, a variable-speed motor, a table and a framework. The conveyor belt can be driven by the variable-speed motor to work, onions can slip onto the conveyor belt from the table via a transition slide rail by the aid of the gravity of the onions, the conveyor belt is sequentially provided with an image acquisition module and a classification mechanism along a conveying direction of the conveyor belt, picture information acquired by a first camera shooting unit, a second camera shooting unit, a third camera shooting unit and a fourth camera shooting unit in the image acquisition module can be transmitted to a CPU (central processing unit) processing center and is processed by the CPU processing center, then signals can be transmitted to corresponding pushing mechanisms, and each pushing mechanism can act under the control of the CPU processing center, so that the pushing mechanisms can act in a reciprocating manner under the control of the CPU processing center to push the onions into corresponding recycling tanks. The intelligent onion sorting device has the advantages that the onions can be finely sorted into diversified grades in sorting procedures, damage to the onions can be detected and inspected in conveying procedures, and the onions with tissue damage can be screened out.

Description

technical field [0001] The invention relates to food processing technology, in particular to an onion intelligent sorting device, which realizes the classification of onions. Background technique [0002] After the onion is picked, in order to meet the market supply demand, onions of different shapes and states need to be sorted. Emerged as the times require, more types of sorting devices have also appeared on the market. Traditional sorting devices cannot meet the requirements of sorting damaged onions, and can only roughly classify onions by size. There are two main types of these traditional sorting devices, one is based on the principle of balance and leverage, using the weight of the container and the weight set by the weighing device to achieve the grading of the selected weight by shifting and measuring during swimming, This type of sorting device has low efficiency and the metering device is easily damaged; the other type is to sort onions by the size of the sieve ...
