Please refer to Figures 1-7, the present utility model is a wolfberry harvester, comprising a frame 1, a chassis 2, a traveling mechanism 3, a control device, a cleaning device 4, a fruit collecting box 5, and a fruit collecting and conveying device , the frame 1 adopts a door-type structure, and the bottom end is connected with the chassis 2; among them, considering the soil characteristics of the wolfberry plantation, the traveling mechanism 3 is a crawler-type traveling mechanism, and the crawler wheel cover 7 is arranged above the traveling mechanism. 3. Provides double-side drive; the fruit collecting box 5 is fixed on both sides of the rear end of the chassis 2, the cleaning device 4 is fixed above the fruit collecting box 5, and the material hopper 6 is fixed above the cleaning device 4; The control device includes a diesel engine 8, a power conversion Device 9 and cab 10.

The wolfberry harvester of the present utility model further includes a vibration excitation device, the vibration excitation device includes a drive device and a vibration rod assembly, the drive device is fixed on both sides of the upper part of the frame 1, and the drive device includes a motor 11, a reduction gear box 12, a turntable 13, a connecting Rod 14 and guide rod 15, the output shaft of the reduction gear box 12 is connected with the turntable 13, one end of the connecting rod 14 is connected in rotation at the eccentric place of the turntable 13, and the other end of the connecting rod 14 is connected with the guide rod 15 in rotation, wherein, the surface of the turntable 13 is provided with an eccentricity The adjustment bolt holes 24 and the eccentric adjustment bolt holes 24 have different eccentric distances, which is convenient for installing the connecting rod 14 in different eccentric positions, so as to achieve the effect of adjusting the amplitude. Common excitation driving devices include inertial vibration exciters, connecting rod type Vibration exciters, hydraulic exciters, electromagnetic exciters, pneumatic exciters, and cam exciters, among which, hydraulic exciters need to be equipped with relevant hydraulic components and hydraulic cylinders, and heavier hydraulic cylinders And the hydraulic device has a high failure rate; the electromagnetic exciter needs to be equipped with power supply and control equipment; the cam exciter is inconvenient for amplitude modulation and the cost of cam manufacturing is high; the pneumatic exciter has insufficient excitation force The driving device in this embodiment is a connecting rod type vibration exciter, which is the preferred solution, which has the advantages of simple processing and convenient amplitude modulation. The specific principle is that the uniform circular motion of the motor 11 is transformed into the linear reciprocating motion of the guide rod 15 , so as to drive the vibrating rod group to exert a forced motion on the fruit-bearing branches to realize the picking effect;

The vibration rod assembly includes a vertical shaft 17 connected to the bottom end of the guide rod 15, wherein the frame 1 is slidably connected to the guide rod 15 through a linear bearing 16, the frame 1 is matched with the vertical shaft 17 through the bearing, and ten fixed shafts are fixed on the peripheral surface of the vertical shaft 17. The plate 18 and the fixed plate 18 are arranged at equal intervals. Twelve vibration rods 19 are detachably fixed on the peripheral side of the fixed plate 18. The number of vibration rods 19 can be adjusted according to the actual tree height during operation. The surface of the vibration rod 19 is covered with silica gel Considering the large inertial force generated by the vibration of the vibrating rod 19 during the operation of the hose cover, and due to the vertical vibration and the rotation of the vertical shaft 17, certain collisions and damages will be caused to the fruiting branches of the wolfberry. Therefore, the stiffness of the vibrating rod 19 has a great influence on the harvesting operation effect. If the stiffness is too large, the bending deformation of the harvesting rod is too small, which will easily damage the branches and increase the damage rate of mature wolfberry. Therefore, in this device, a 4mm thick silicone hose is used to coat the 45# round steel vibrating rod 19. The advantages of the silicone hose are: excellent flexibility, kink resistance and no deformation, high tear strength, non-toxic, It has the advantages of high temperature resistance, low temperature resistance, long life and long-term use without hardening. In actual work, the length of the vibrating rod 19 is greater than half of the maximum diameter of the fruit tree. Through the actual investigation, the canopy width of the wolfberry fruit tree cultivated for 4 years is 1.3-1.6 m, and the root neck of the tree is 38 mm thick. Therefore, the vibrating rod 19 can be determined. The length is 750mm and the diameter is 10mm. Through the actual measurement of the particle size of wolfberry fruit, the results show that the average longitudinal diameter of the fresh fruit is 18.3mm, and the transverse diameter is 9.4mm, so it can be determined that the distance between the two vibrating rods 19 is at least not less than 18.3mm, which is radial on the fixed plate 18. Arrangement, while considering the rolling performance of the vibrating rod group in the actual working process, it is determined that twelve vibrating rods 19 are evenly arranged on each fixed plate 18 at equal angles.

Among them, the fruit collecting and conveying device is arranged between the two sides of the frame 1, including a horizontal conveyor belt 20, an inclined conveyor belt 21 and a fruit collecting plate 22, and the tail end of the inclined conveyor belt 21 extends to the top of the material hopper 6 of the cleaning device 4 , cooperate with the horizontal conveyor belt 20 for fruit conveying and improve the working efficiency of the machine. The conveyor belt adopts PVC conveyor belt, which is pollution-free and does not produce peculiar smell; A strip-shaped barrier is provided, and a rubber collecting plate 23 is fixed on one side of the fruit collecting plate 22; the fruit collecting plate 22 is made of a thin iron plate and a smooth plastic plate attached to it. The selection of smooth plastic plate helps the wolfberry fruit to slide down on the horizontal conveyor belt; the bar-shaped block can effectively prevent the fruit from colliding with each other during the sliding process, reduce the degree of damage to the fruit, and prevent the falling of the fruit. The fruit is too concentrated in a certain area and is not conducive to sliding down to the horizontal conveyor belt; the fruit collection plate is installed at an angle of 30° to the ground, so that the vibrated wolfberry fruit falls to the horizontal conveyor belt 20 under the action of its own gravity; the rubber collection plate 23 The distance between the collecting plates on both sides can be kept as small as possible to prevent the shaken fruits from falling to the ground from the middle gap. In addition, since the harvester needs to keep driving in a straight line during the traveling process, it can ensure efficient harvesting operations. The soft rubber collecting plate 23 can also reduce the damage of the collecting plate to the tree trunk.

A specific application of this embodiment is: when working, the harvester runs in a straight line at a certain speed, and rides on the wolfberry fruit tree. The vibration rod components of the vibration excitation device distributed on both sides of the vehicle body are evenly inserted into the tree body and vibrate up and down. Under the action of the exciting force of the vibrating rod group, the drooping fruit-hanging branches separate the wolfberry fruit from the tree body and fall, and then roll down to the horizontal conveyor belt 20 by the two oblique fruit collecting plates 22 installed under the vehicle body, and then convey through the inclined conveyor. The belt 21 enters the cleaning device 4 through the material hopper 6, and finally enters the two fruit collecting boxes 5 respectively to realize mechanized harvesting.
