The application provides a big green onion picking and packing integrated machine, and belongs to the technical field of agricultural machinery. It solves the problems of traditional big green onion processing methods, high labor intensity, low manual efficiency and low economic benefits. The big green onion picking and packing integrated machine comprises a conveying device, a positioning and leaf cutting device, a grading device and a bundling device. The positioning and leaf cutting device is used for positioning and correcting the big green onion. The conveying device is used for clamping and removing the big green onion and conveying the big green onion backward and upward. In the conveying process, the positioning and leaf cutting device cuts the leaves of the big green onion. A plurality of grading devices are sequentially arranged on the frame. The grading devices are used for distinguishing and classifying the big green onions with different diameters. The bottom of each grading device is provided with a bundling device. The bundling device is used for gathering and bundling the big green onions. The big green onion picking and packing integrated machine has the advantages of improving the efficiency of big green onion harvesting and post-processing, improving the agricultural production efficiency and reducing the labor cost.

The application provides a method for recovering tungsten from molybdenum tailings, comprising the following steps: centrifugal gravity separation of the molybdenum tailings to obtain centrifugal concentrate and centrifugal tailings; feeding the centrifugal concentrate into a spiral chute for secondary separation to obtain spiral chute concentrate and spiral chute tailings; conventional flotation of the spiral chute concentrate to obtain primary roughing concentrate, primary scavenging concentrate and scavenging tailings; mixing the primary roughing concentrate and the primary scavenging concentrate and feeding the mixture into a cyclone classifier, the overflow of the cyclone classifier being subjected to gravity separation operation on a table, and the underflow of the cyclone classifier being subjected to grinding in a ball mill, the ball mill and the cyclone classifier forming a closed circuit grinding system to obtain table concentrate and table tailings; three times of cleaning and one time of cleaning scavenging of the table tailings to obtain flotation concentrate and cleaning scavenging tailings; mixing the table concentrate and the flotation concentrate to obtain tungsten concentrate; and mixing the centrifugal tailings, the spiral chute tailings, the scavenging tailings and the cleaning scavenging tailings to obtain total tailings. The application improves the recovery rate of the tungsten concentrate.

This invention provides a nano-light-purifying green intelligent aeroponic system and an integrated planting and breeding system, belonging to the field of aeroponic device technology. It includes a cultivation module, a nutrient solution circulation supply module, an ultrasonic atomization module, an AMF microbial agent processing module, an auxiliary adjustment module, a harvesting module, a control and monitoring module, and a solar power supply module. The cultivation module provides suitable growing space for crops; the nutrient solution circulation supply module circulates the nutrient solution needed for crop growth on the cultivation module. The nano-light-purifying green intelligent aeroponic system of this invention features a cultivation rack with a sloping three-dimensional triangular or trapezoidal structure, which is simple to manufacture and has low labor and cost. The nutrient solution circulation supply module is installed under the cultivation rack to collect and recycle the nutrient solution after supply, achieving recycling and improving the utilization rate of the nutrient solution. Furthermore, the integrated planting and breeding system integrates planting, harvesting, and breeding, improving agricultural production efficiency.

This utility model discloses a fishing device for fish identification, belonging to the technical field of fishing devices. It includes an L-shaped main board with a fishing mechanism inside. The fishing mechanism includes an electric push rod embedded in the inner left wall of the L-shaped main board. A fishing frame is fixedly installed at the telescopic end of the electric push rod. A fish inlet corresponding to the fishing frame is fixedly installed on the inner rear wall of the L-shaped main board, and a fish storage cage is installed to the right of the fish inlet. Through the fishing mechanism, this utility model can dynamically capture and identify fish using a visual sensor. The electric push rod is controlled by a controller, causing the fishing frame to move to the right, trapping the fish inside. Then, the rightward movement of a push plate pushes the fish through the fish inlet and the fish-blocking plate into the fish storage cage. This process repeats, achieving automatic fishing. The principle is simple while improving the fishing yield.

The embodiment of the invention relates to the technical field of agricultural planting, in particular to an illumination intensity adjusting method, greenhouse control equipment and a storage medium, the greenhouse control equipment is in communication connection with illumination equipment, and reference illumination intensity suitable for crop growth is calculated according to the growth stage and growth data of crops; therefore, the illumination equipment is controlled to work at the power corresponding to the reference illumination intensity, so that the illumination intensity of the crop planting greenhouse is taken as the reference illumination intensity, the illumination intensity suitable for each growth stage is provided for crops, the crop growth and fruiting conditions are improved, the crop yield is improved, and the economic benefits of the crops are improved.
