[0035] See also Figure 7 A first fruit leaf separation plate 5 and a second fruit leaf separation plate 6 are provided at the top of the fruit collecting frame 4. The first fruit leaf separation plate 5 and the second fruit leaf separation plate 6 are both obliquely arranged at the top opening of the fruit collecting frame 4. The bottom edge of the first fruit leaf separation plate 5 is obliquely connected to the left side of the top of the fruit collecting frame 4, and the top edge is connected to the top edge of the second fruit leaf separation plate 6 through a pin 7. The bottom edge of the second fruit leaf separation plate 6 is obliquely connected to the right side of the top of the fruit collecting frame 4. The first fruit leaf separation plate 5 and the second fruit leaf separation plate 6 are both densely arranged with circular holes.

[0036] This embodiment mainly consists of a vehicle frame 1, a bucket 10, a rod group for controlling the flipping of the bucket 10 (i.e., a flip-type harvesting device), and a rod group for controlling the movement of the cleaning rod (i.e., a cleaning mechanism). The handle on the vehicle frame 1 is manually pushed to drive the wheels 2 and the wheel axle 3 to rotate, thereby realizing the movement of the entire vehicle. The bucket 10 is at a certain distance from the ground under the action of the front horizontal bracket 104 of the vehicle frame 1. The front end of the bucket 10 has dense comb teeth 1001, and its rear end is hinged to the middle vertical bracket 103 in the middle of the vehicle frame 1. When the entire vehicle moves forward, the bucket 10 shovels the lowbush blueberry fruits into the space of the bucket 10, completing a blueberry picking.

[0037] When the bucket 10 is full of blueberries, the vehicle is stopped from being pushed forward, and the first handle 13 is manually pulled forward, the first handle 13 drives the first connecting rod 12, and the first connecting rod 12 drives the second connecting rod 11, so that the bucket 10 rotates around the hinged portion between the bucket 10 and the vehicle frame 1 (the rotated bucket 10 is as shown in FIG. Figure 3 and Figure 4 As shown in the figure, the blueberry fruits in the bucket 10 are poured into the fruit collecting frame 4. A first fruit and leaf separation plate 5 and a second fruit and leaf separation plate 6 are provided above the fruit collecting frame 4. Circular holes are densely arranged on the first fruit and leaf separation plate 5 and the second fruit and leaf separation plate 6 are provided on the fruit collecting frame 4. The two plates are connected by a pin 7 in the middle and are installed on the frame 1 at a certain oblique angle. When the fruits are poured into the fruit collecting frame 4, only the fruits can pass through the first fruit and leaf separation plate 5 and the second fruit and leaf separation plate 6. The stems and leaves naturally fall to both sides under the action of the oblique angle, completing one blueberry collection.

[0038] After that, the first handle 13 is manually reset. The comb teeth 1001 at the front end of the bucket 10 may contain stems and leaves that were cut off and stuck when shoveling blueberries. At this time, the second handle 23 is manually pushed backward to drive the third connecting rod 22 to move. The third connecting rod 22 drives the fourth connecting rod 21 to rotate around the hinge between it and the front horizontal bracket 104 of the frame 1, thereby pushing the cleaning rod 20 to move toward the front end of the bucket 10 (the cleaning rod 20 after moving is as shown in FIG. 1 ). Figure 5 and Figure 6 As shown in the figure, the lower surface of the cleaning rod 20 is always in contact with the inner surface of the bucket 10 to clean the stems and leaves stuck in the comb teeth 1001 at the front end of the bucket 10. After one cleaning is completed, the second handle 23 is reset, and the torsion spring 24 installed between the handle and the second handle 23 overcomes its gravity to achieve automatic reset (the torsion spring 24 is sleeved on the top horizontal rod 101 at the top of the frame 1, one end of the torsion spring 24 is connected to the second handle 23, and the other end is connected to the handle). Complete a complete blueberry harvesting action.

[0039] When the first handle 13 is pulled to flip the bucket 10 , the lower surface of the cleaning rod 20 is always in contact with the inner surface of the bucket 20 , and rotates around the fourth connecting rod 21 under the action of the bucket 10 without causing interference.

[0040] When the fruit collecting frame 4 is full of fruits, it is pulled out, and the fruit collecting frame clamp 8 rotates and loosens naturally under its action. When the empty fruit collecting frame 4 is placed in the middle vertical bracket 103 of the frame 1, the fruit collecting frame clamp 8 naturally clamps the fruit collecting frame 4 under the action of the internal torsion spring, preparing for the next round of blueberry harvesting.

[0041] This embodiment provides a flip-type shortbush blueberry harvester in view of the growth characteristics of shortbush blueberries. The front end of the bucket 10 has dense comb teeth 1001, and its rear end is hinged on the bracket in the middle of the frame 1. When the whole vehicle moves forward, the bucket 10 shovels the shortbush blueberry fruit into the space of the bucket 10 through the dense comb teeth 1001, completing a blueberry picking. It is suitable for the harvesting of shortbush blueberries, reducing the difficulty of harvesting shortbush blueberries. Compared with the pure manual picking method, the labor intensity is low and the efficiency is high. This embodiment controls the flipping of the bucket 10 and the movement of the cleaning rod 20 by a pure handle to achieve the collection of blueberry pulp and the cleaning of stems and leaves. It has a simple structure, is convenient and practical, and has a light weight and low cost. This embodiment can separate the blueberry fruit from the stems and leaves through the first fruit and leaf separation plate 5 and the second fruit and leaf separation plate 6 when harvesting blueberries, providing convenience for the later processing of blueberries.

[0042] The protection scope of the present technology includes but is not limited to the above embodiments. The protection scope of the present technology shall be based on the claims. Any replacement, deformation, and improvement of the present technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present technology.
