Fig. 1 is a schematic structural diagram of the present invention.
The labels in the figures are: 1-picking head, 11-swinging disk, 12-vibrating rod, 2-speed reducer, 3-handle, 4-flexible shaft component, 5-switch, 6-battery power box and 7-swinging motor.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Example 1. A handheld lightweight blueberry picking device is shown in figure 1 and comprises a handheld picking unit and a power output unit; the handheld picking unit comprises a picking head 1, the picking head 1 is connected with an output shaft of a speed reducer 2, and a handle 3 is arranged at the tail end of the speed reducer 2; the power output unit comprises a battery power supply box 6, a swing motor 7 is arranged in the battery power supply box 6, and the swing motor 7 supplies power through a battery assembly arranged in the battery power supply box 6; an output shaft of the swing motor 7 is connected with one end of the flexible shaft assembly 4, the other end of the flexible shaft assembly 4 penetrates through the handle 3 and is connected with the speed reducer 2.
During the use, handheld handle 3 inserts the blueberry branch with picking head 1, later starts swing motor 7 reciprocal swing to transmit the swing moment of torsion for reduction gear 2 through flexible axle subassembly 4, final drive picking head 1 reciprocal swing realizes shaking the blueberry fruit from the branch and drops.
The position of the handle 3 close to the thumb is provided with a switch 5 for controlling the start/stop of the swing motor 7. This arrangement makes it more convenient to start/stop the swing motor 7.
The picking head 1 comprises a swinging disc 11, and more than one vibrating rods 12 are distributed on the circumference of one end surface of the swinging disc 11; the center of the other end face of the swinging disc 11 is connected with an output shaft of the speed reducer 2.
The vibrating rod 12, the swinging disk 11 and the handle 3 are all made of Polyformaldehyde (POM) materials, so that the aim of light weight is further fulfilled.
Four vibrating rods 12 are distributed on the circumference of one end face of the swinging disc 11.
The picking mode of the picking head 1 is as follows: insert the blueberry branch with vibrating arm 12, make the blueberry branch be in between vibrating arm 12, vibrating arm 12 can drive the blueberry branch and constantly rock when reciprocating swing to make the blueberry drop from the branch.
The battery power box 6 is a strap-type power box.
When the blueberry is picked by the picking head 1, the branch shaking state of the picking head 1 is controlled by the swing frequency and the swing amplitude of the swing motor 7; specifically, the swing frequency is controlled by the time for turning on the rotor of the swing motor 7 in a forward and reverse rotation manner, and the swing amplitude is controlled by the current passing through the swing motor 7; the maximum current through the oscillating motor 7 can be preset; when the picking head 1 touches the branches of the blueberries and the swing motor 7 reaches the maximum current, the swing amplitude is not increased any more; when the reverse opening time is up, the picking head 1 rotates reversely to shake the branches. The control method is a control mode of coupling the swing frequency and the swing amplitude, and realizes the coupling control of the swing frequency and the swing amplitude by setting the maximum current of the swing motor (namely, setting the maximum swing force) and the positive and negative rotation turn-on time of the swing frequency motor. The control method effectively shakes and falls off the fruits from branches with different thicknesses by adjusting the maximum swinging force and the vibration frequency in real time respectively.
