TECHNICAL FIELD
[0001] The present application belongs to the technical field of small berry harvesting, and particularly relates to a small berry vibration harvesting device with staggered arrangement. BACKGROUND
[0002] Blueberries, currants, sea buckthorn, blue honeysuckle, and black chokeberry are common small shrub berries. These fruits have the characteristics of short ripening period, easy breakage, and small size, so the harvesting of small berries is difficult. Therefore, in order to realize the mechanized harvesting of small berries, various harvesting devices are disclosed in the prior art. In patent CN115413486A, a towable lifting V-shaped vibration type small berry harvester is disclosed, which includes a frame, a towing device, a shrub divider, a shrub lifting device, a shrub guiding device, a vibration picking device, and a fruit collecting device. The towing device is arranged on one side of the front end of the frame. The shrub divider is located at the center of the front end of the frame. The shrub lifting devices are symmetrically arranged on the inner side of the front end of the frame, and the front end extends out of the frame. The shrub guiding devices are arranged on both sides of the shrub divider. An auxiliary collecting device is arranged below each shrub guiding device. The vibration picking devices are symmetrically and obliquely installed at the rear end of the shrub divider, and the two vibration picking devices are arranged in a V shape. The inclination angle of the auxiliary collecting device is equal to the inclination angle of the vibration picking device. A fruit collecting device is arranged below the auxiliary collecting device. The fruit collecting device is connected to a conveying device, and the conveying device sends the small berries to a cleaning device located at the rear of the frame. However, because the vibration picking device of the harvester is arranged in a V shape, the overall width of the machine is large, and the effective working area is greatly limited. The working angle can only be switched between a few preset angles. Moreover, the manual switching operation of the working angle is difficult, and the machine cannot automatically adjust and work at any angle. The machine has poor adaptability. When adjusting the working angle, the vibration probes of the vibration device will interfere with each other, and smaller vibration probes must be replaced. However, smaller vibration probes will reduce the vibration area and cannot cover the entire vibration area formed by the upper guide rod and the lower guide rod, affecting the harvesting effect.

[0027] As shown in Figure 8 The left vibration harvesting device 3 and the right vibration harvesting device 4 are both rotary reciprocating vibration type small berry picking devices, and the left vibration harvesting device 3 is taken as an example for description, which specifically comprises a vibration power device 3a, a vibration shaft assembly 3b and a vibration disc assembly 3c; the vibration power device 3a is connected with the vibration shaft assembly 3b, and the vibration disc assembly 3c is installed on the vibration shaft assembly 3b. As shown in Figure 9 , Figure 10 The vibration power device 3a comprises a driving assembly 3a-1, which is connected with a power output shaft assembly 3a-4 through a shaft coupling 3a-2 for power transmission, and the power output shaft assembly 3a-4 passes through a power conversion shaft assembly 3a-3 and is installed on a vibration device housing 3a-7 through a bearing; in the vibration device housing 3a-7, a first eccentric wheel assembly 3a-5 and a second eccentric wheel assembly 3a-6 symmetrically installed in the vibration device housing 3a-7 are driven to rotate by a synchronous belt transmission device; A brake disc 3a-7a is arranged on the vibration device housing 3a-7, and a belt brake 3a-8 is sleeved on the brake disc; at the same time, the vibration device housing 3a-7 rotates reciprocatingly under the driving of the rotational torque formed by the first eccentric wheel assembly 3a-5 and the second eccentric wheel assembly 3a-6 as a power output part; the belt brake 3a-8 always gives the vibration device housing 3a-7 a reverse damping force; the pre-tightening force and elastic element of the belt brake 3a-8 can be adjusted to adjust the amplitude and frequency of the reciprocating rotation of the vibration device housing; the power conversion shaft assembly 3a-3 makes the driving assembly stationary.
[0028] The vibration device shell 3a-7 is connected by a rivet, facilitating disassembly, maintenance, and adjustment of the counterweight. The vibration device shell 3a-7 has weight reduction holes on the front and back and left and right, which not only reduce the weight of the vibration device but also facilitate observation of the working state of the device.
[0029] As shown in FIG. 1, the belt brake 3a-8 is composed of a brake belt 3a-8a, a balance bar 3a-8b, damping rubber 3a-8c, a connecting rod 3a-8d, and an elastic element 3a-8e. Figure 11 Figure 13 The brake belt 3a-8a is sleeved on the vibration device shell brake disc 3a-7a, always providing a reverse damping force to the vibration device shell. The balance bar 3a-8b has a middle fixed mounting disc 3a-8b-1. The damping rubber 3a-8c is symmetrically placed in the disc. The inside of the mounting disc is provided with a first stop block 3a-8b-2. The mounting disc is matched with a first rotating shaft 3a-8b-3. The first rotating shaft 3a-8b-3 serves as the rotating center of the brake belt 3a-8a. The two ends of the balance bar are also provided with a second rotating shaft 3a-8b-4 (the balance bar is fixedly connected with the second rotating shaft 3a-8b-4), which is used for mounting the brake belt. The brake belt is rotationally connected with the second rotating shaft 3a-8b-4, so that the brake belt 3a-8a drives the balance bar 3a-8b to make reciprocating rotary motion around the middle first rotating shaft 3a-8b-3 of the mounting disc.
[0030] One end of the connecting rod 3a-8d is provided with a disc 3a-8d-1. The bottom of the disc 3a-8d-1 is provided with a second stop block 3a-8d-2. The middle of the disc 3a-8d-1 is provided with a round hole 3a-8d-3, which is fixedly connected with the first rotating shaft 3a-8b-3. The disc 3a-8d-1 is matched with the mounting disc 3a-8b-1 of the balance bar above and below, providing resistance to the damping rubber in the mounting disc.
[0031] When the mounting disc 3a-8b-1 reciprocates with the brake belt 3a-8a, the first stop block 3a-8b-2 exerts pressure on the rubber block 3a-8c. During the reciprocating process of the brake belt, the connecting rod 3a-8d is stationary. At this time, the second stop block 3a-8d-2 on the connecting rod 3a-8d will provide resistance to the damping rubber 3a-8c, preventing it from continuing to swing. The force of the balance bar swinging is generated by the friction between the brake belt and the brake disc. The function of the second stop block 3a-8d-2 is to provide resistance. To ensure that the brake belt provides the same friction during the reciprocating rotation of the vibration device and that the balance bar swings reciprocally, the two stop blocks are arranged in a straight line, dividing the mounting disc into two symmetrical regions of the same size, and the same two damping rubbers 3a-8c are symmetrically placed.
[0032] When the vibration device housing 3a-7 drives the brake band 3a-8a to deflect to one side, the damping rubber 3a-8c will give the brake band 3a-8a a resistance through the mounting disc 3a-8b-1 to prevent it from deflecting too much with the vibration device housing, at this time, the brake band 3a-8a will also give the brake disc 3a-7a a larger resistance, so that the vibration device housing 3a-7 gradually stops deflecting until it starts to deflect to the other side. This reciprocates.
[0033] The other end of the connecting rod 3a-8d is provided with a screw thread 3a-8d-4, and by adjusting the tightness of the adjusting nut 3a-8d-5, the tightness of the elastic element 3a-8e can be adjusted, so as to adjust the pre-tightening force of the brake band 3a-8a to the brake disc 3a-7a. Used to adjust the friction between the brake band 3a-8a and the brake disc 3a-7a, so as to adjust the amplitude and frequency of the vibration device housing rotating reciprocating.
[0034] The vibration harvesting operation module of the present application adopts modular design, adopts a transformed "V" shape arrangement, and the operation area can be adjusted by one key according to different tree ages and different tree shapes, and has strong adaptability. When the machine performs harvesting operation, the divider distributes the shrub branches to both sides, the shrub lifting device assists the auxiliary shrub lifting device to lift the bottom branches upward, and the branches enter the vibration operation area through the guide device. The fruits falling off are directly fallen into the collecting device, and most of them are fallen onto the auxiliary collecting device and further rolled into the collecting device. The collected fruits slide into the conveying device, the conveying device conveys the fruits to the rear of the machine and lifts them to a certain height, and after being cleaned by the cleaning device, the fruits are fallen into the fruit collecting basket.
