Detailed description of the working principle

The wolfberry harvesting and sorting all-in-one machine provided by the invention can efficiently pick wolfberry, remove impurities from the picked wolfberry, and screen and sort the wolfberries of different sizes.

The harvesting mechanism is designed and realized based on the principle of a swing guide rod driven by a gear train, and compared with the existing vibration harvesting technology, the vibration harvesting mechanism has larger vibration amplitude and more thorough harvesting. Before the mechanism moves to work, an operator needs to operate the operating rod to enable the machine to enter under the Chinese wolfberry tree; and then, starting the first vibrating motor, enabling the planetary gear train to rotate at a high speed through transmission of a belt wheel, and simultaneously driving the guide rods 2-19 to rotate to drive the vibrating short rods 2-17 to swing up and down at a high speed. The short vibrating rod transmits the motion rule to the vibrating rod 2-1, so that the vibrating rod 2-1 vibrates at a high speed to flap the medlar, and the medlar is collected by the collecting cover. Different picking heights can be realized by adjusting the lifting mechanism; the vibrating bottom plates 2-8 are driven by the lifting motor to move up and down, and the vibrating mechanisms arranged on the vibrating bottom plates 2-8 can move along with the vibrating bottom plates, so that the picking of the Chinese wolfberry with different heights is realized.

The medlar collected by the collection cover 3-15 falls onto the sieve 3-12 along the slope plate 3-13 in the collection cover; under the drive of the cam box 3-1, the push rod 3-6 moves back and forth at a high speed to drive the sieve to vibrate at a high speed, so that impurities or excessively small fruits in the Chinese wolfberry are removed, and the removed impurities fall into the impurity removing box 3-9 (after picking, the impurity removing box needs to be treated). Because the sieve and the horizontal plane have an angle of 1.5 degrees, the medlar can gradually move to the collecting plate 3-11 under the action of exciting force and gravity, so that the medlar can fall into the feeding port 4-1 and enter the first inclined disc 4-3 in the sieve cylinder 4-2, and the medlar with different sizes can be fully screened out under the drive of the vibrating motor 4-19, the larger medlar can be retained in the first disc, and the smaller medlar can fall from sieve holes of the first disc and fall into the second disc; the smallest medlar falls from the sieve holes of the second round plate and falls into the third round plate; the motors 4-13 drive the three discs to rotate at a constant speed, and the medlar on each disc gradually enters the outer discs 4-6 through 4 medlar guide-out grooves uniformly distributed on the corresponding layer under the action of gravity and centrifugal force; under the drive of the planetary gear train, the internal gear 4-11 rotates at a lower speed to drive the three outer disks 4-6 to rotate at a constant speed, and the push plate 4-30 fixed on the screen drum shell and suspended on the upper edge of the outer disks pushes the Chinese wolfberry to be moved on the outer disks into the transmission channel 4-29, so that the Chinese wolfberry enters different containing boxes of different containing boxes to wait for an operator to take out the Chinese wolfberry.
