[0002] Lycium barbarum is a deciduous shrub, 1.5 to 2 meters high, with an open crown and slender branches. The tips are usually bent and drooping, often in the shape of thorns. It has many health benefits and is mainly produced in Inner Mongolia, Ningxia, Xinjiang, Gansu and other places in my country. With the increase in the implementation of the "Three Norths" shelterbelt and returning farmland to forest and the strong pull of the market demand for wolfberry, the planting area of ​​wolfberry in my country has expanded rapidly. With the large-scale and standardized production of wolfberry and the continuous improvement of the planting management level, the demand for agricultural mechanization technology has increased rapidly. Due to the irregular growth and pruning of wolfberry branches, the harvesting technology of wolfberry fruit is very difficult. During the peak period of wolfberry picking, the manual harvesting method is inefficient, resulting in a large number of wolfberries that cannot be picked in time, causing huge losses to farmers' income. Therefore, the development of an efficient and accurate wolfberry picking machine is of great significance to promoting the industrialization development of wolfberry in my country.

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] Figure 1The control system schematic diagram of a handheld pulse magnetic vibration wolfberry harvester is shown in the figure. The control panel includes a single chip microcomputer, a power lithium battery, a DC-DC buck, a vibration force "+" button, a vibration force "-" button, a vibration frequency "+" button, a vibration frequency "-" button, a start button, a stop button, an optical coupler I, a field effect tube I, a core coil I, an optical coupler II, a field effect tube II and a core coil II. The power lithium battery can output 12V or 24V, and a 5V voltage is obtained through the DC-DC buck to power the single chip microcomputer. The power lithium battery is also used to power the field effect tube I and the field effect tube II. After pressing the start button, the single chip microcomputer generates a pulse magnetic field by controlling the optical coupler I and the field effect tube I, and generates a pulse magnetic field by controlling the optical coupler II and the field effect tube II; each time the vibration force "+" button or the vibration force "-" button is pressed, the vibration force of the vibration shaft 20 is also increased or decreased accordingly. Similarly, each time the vibration frequency "+" button or the vibration frequency "-" button is pressed, the vibration frequency of the vibration shaft 20 increases or decreases accordingly. When the stop button is pressed, the single chip microcomputer stops working.

[0027] Figure 2 The diagram is a harvesting function diagram of a handheld pulse magnetic vibration wolfberry harvester. When working, first grasp the tip of the wolfberry branch 16, and place the system below the wolfberry branch 16, so that the position of the swing rod 21 is flush with the position of the wolfberry stalk 17. The single-chip microcomputer generates a pulse magnetic field with adjustable frequency through a power lithium battery and a coil with an iron core. The pulse magnetic field causes the horizontal swing vibration mechanism to reciprocate along the axial direction of the wolfberry branch 16 at a certain frequency and amplitude through the magnet 23 on the vibration shaft 20. The ripe wolfberry fruit 18 falls off the branch quickly through the swing rod 21, and part of the fallen fruit falls directly into the box 19, and the other part of the fruit that is vibrated to the inner edge of the box falls along the inner wall of the box. The silica gel on the inner wall of the box can protect the wolfberry from damage and realize the lossless harvest of the wolfberry. Through holes are opened at both ends of the box 19 to fix the spring 22 and allow the magnetic field to circulate. A handle 25 is installed at the rear end of the box 19 so that the system can be handheld for operation. The wolfberries in the box 19 can be poured into a designated device through the discharge port 24 to carry out the next operation, and so on.

A magnet 23 is installed at each end of the vibration shaft 20, and the outer end faces of the two magnets 23 coincide with the end face of the vibration shaft 20. The two magnets 23 are placed in parallel and have opposite magnetic poles. Five swing rods 21 are installed at equal intervals in the middle of the vibration shaft 20. The height of the swing rod 21 located in the center is 2mm higher than the two adjacent swing rods and 4mm higher than the two outer swing rods. A silicone tube 26 is sleeved on the swing rod 21 to reduce the probability of damage to mature wolfberries. The swing rod 21 is connected to the vibration shaft 20 by welding. The two ends of the vibration shaft 20 are connected to the box 19 by a spring 22, so that it can do swaying motion under the action of the pulse magnetic field.
