It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

As shown in Figures 1 to 5, a blueberry picking machine capable of bidirectional movement comprises a bottom plate 1, a frame 2, a fruit receiving plate 3, a picking device 4, a chute 5, a conveying device 6 and a fruit basket 7. The frame 2 is an inverted U-shaped frame structure, the bottom plate 1 is transversely fixed to both sides of the bottom end of the frame 2, a roller 8 is arranged at the bottom of the bottom plate 1, the fruit receiving plate 3 is symmetrically arranged on the inner side of the frame 2 in an eight-shaped shape, the picking device 4 is symmetrically arranged on the bottom plates 1 on both sides and each comprises a longitudinally arranged toggle roller 41 and a motor 42 and a bevel gear box 43 respectively fixed on the base 1, the output shaft of the motor 42 is connected to the bottom plate 1, and the output shaft of the motor 42 is connected to the bottom plate 1. The bevel gear box 43 is connected to the toggle roller 41 through transmission. The toggle roller 41 is provided with a plurality of toggle teeth 411. Open grooves are provided at positions corresponding to the toggle rollers 41 on both sides of the frame 2. Parts of the toggle teeth 411 extend into the open grooves. The inclined grooves 5 are symmetrically arranged at the bottom openings of the vertical plates on both sides of the frame 2 and are inclined. A plurality of collecting holes 51 are longitudinally arranged in the inclined grooves 5. The conveying device 6 includes a conveying frame 61 located at the bottom of the inclined groove 5. A conveying belt 63 driven by a reduction motor 62 is provided on the conveying frame 61. The fruit basket 7 is located at the end of the transmission direction of the conveying belt 63.

Among them, the fruit receiving plate 3 includes an inclined fixed plate 31, a rotating shaft 32, a limit spring 33 and a plurality of toggle plates 34, the inclined fixed plate includes a transverse plate fixed to the frame 2 and an inclined plate inclined to the transverse plate, the rotating shaft 32 is vertically fixed on the inclined plate at equal intervals, the back of the toggle plate 34 is rotatably connected to the rotating shaft 32 through an end face bearing seat, the limit spring 33 is symmetrically arranged on both sides of the end face bearing seat, and the two ends of the limit spring 33 are respectively connected to the transverse plate and the toggle plate 34 through connecting columns; the bevel gear box 43 includes a pair of mutually meshing bevel gears, and the two bevel gears are respectively fixedly connected to the output shaft of the motor 42 and the shaft head of the toggle roller 41; the ends of the toggle teeth 411 are provided with rubber sleeves 412, which can prevent the toggle teeth 411 from damaging the blueberry fruit during the beating process and reduce the fruit damage rate; the two sides of the conveying frame 61 are respectively provided with baffles higher than the conveyor belt 63, which can prevent the blueberry fruit from falling onto the conveyor belt 63 and then sliding off.

The present invention mentions a bidirectionally movable blueberry picker, which, when used specifically, is used as a traction device, and its movement is towed by a power device. Specifically, at least one traction connection hole is provided at the front end and the end of one side of the base plate 1, and the entire blueberry picker is connected to the power device through one or more traction connection rods. The traction connection can refer to the currently used agricultural equipment, such as traction plows, traction seeders, etc., which are already well-known to those skilled in the art and will not be elaborated here.

Before picking, the device is located at the front end of a single row of blueberry trees, so that the blueberry trees in the row are in the middle position of the frame 2, and the power equipment and the roller 8 located at the bottom of the bottom plate 1 are located in the gap between two adjacent rows of blueberry trees. The reduction motor 62 and the motor 42 can be powered by one or more batteries arranged on the bottom plate 1. During the picking process, the two symmetrically arranged toggle rollers 41 rotate towards each other, and along the walking direction of the entire machine, the blueberries on the branches of the blueberry tree are slapped toward the cavity between the two vertical plates of the frame 2, so that the blueberry fruits fall onto the toggle plate 34, slide along the toggle plate 34 into the chute 5, and then fall onto the conveyor belt 63 through the collection drop hole 51 on the chute 5, and then under the action of the reduction motor 62, the conveyor belt 63 circulates and transports the blueberry fruits and transports them into the fruit basket 7 at its end.

It is worth mentioning that in the two symmetrical picking processes, when the picking machine enters the blueberry bush, the toggle plate 34 is pushed toward the rear side in turn by the force of the tree trunk, and the toggle plate 34 rotates around the rotating shaft 32. The limit springs 33 on both sides of the rotating shaft 32 are in a compressed state and in a stretched state respectively. The inclination angle of the toggle plate 34 is absolutely determined according to the size of the blueberry trunk. The larger the trunk, the greater the inclination amplitude of the toggle plate 34. Only after the toggle plate 34 is tilted can a larger space be formed between the two symmetrical toggle plates 34, which is sufficient to accommodate the blueberry trunk. During the whole process, multiple toggle plates 34 can enable the entire fruit receiving plate 3 to continuously clamp the branches to prevent the blueberry fruits from falling to the ground during the picking process, thereby realizing the contour of the toggle plate 34 and the blueberry trunk. After the fruit receiving plate 3 leaves the blueberry bush, the toggle plate 34 returns to its initial state under the action of the restoring force of the limit spring 33.

When picking in the opposite direction, the entire picking machine does not need to turn, and only the motor 42 needs to be changed, and the toggle plate 34 can swing forward and backward, thereby realizing two-way walking and picking, and improving the picking efficiency.

In addition, the roller 8 used in the present invention can be a Mecanum wheel, which can achieve longitudinal walking and lateral walking at the same time.

The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
