Description

Technical Field

[0001] This utility model relates to the technical field of blueberry picking equipment, and in particular to a vibrating blueberry picking machine. Background Technology

[0002] Blueberries, scientifically known as Vaccinium bracteatum, are perennial deciduous fruit trees, shrubs with blue, nearly round berries. The berries have delicate flesh, tiny seeds, a balanced sweet and sour taste, and a pleasant aroma. Currently, after blueberries ripen, they are typically harvested using vibrating blueberry harvesters. These machines work by moving a traveling mechanism along the blueberry bush and continuously vibrating the upright lateral branches, creating pressure on the fruit and separating it from the branch. Finally, a belt conveyor transports the shaken-off blueberries into collection boxes, achieving efficient harvesting. However, in actual harvesting, this equipment also shakes off fallen leaves and branches, which not only get mixed in with the blueberries and are transported to the collection boxes along with the belt conveyor, but also easily jam the conveyor's moving parts, affecting its operational stability.

The fallen blueberries then enter the rectangular box through the gap between the receiving plate and the baffle at the opening. They are then conveyed by the screw conveyor and screw lifting mechanism into the collection trolley following behind the equipment. Due to their larger length and volume, most fallen leaves and branches are blocked at the entrance of the rectangular box before the blueberries enter, thus easily separating them from the blueberries. Furthermore, the screw conveyor and screw lifting mechanism are not easily jammed by fallen leaves and branches, ensuring a stable and safe blueberry transport process. Attached Figure Description

[0023] Example: A vibrating blueberry harvester, such as Figures 1-4 As shown, it includes a portal frame 1, a pair of rectangular boxes 2 fixedly connected to both ends of the portal frame 1 with their openings facing upwards, multiple parallel and spaced baffles 3 fixedly installed at the openings of the rectangular boxes 2, a pair of wheels 4 rotatably mounted on the bottom of the rectangular boxes 2, a spiral conveyor mechanism 5 installed inside the rectangular boxes 2 for conveying blueberries, multiple inclined receiving plates 6 with one end hinged to the top of the rectangular boxes 2, an angle reset mechanism 7 installed on the back of the receiving plates 6, a pair of connecting rods 8 vertically suspended on the two receiving plates 6, and multiple... A rotating ring 9, parallel and spaced vertically and rotatably sleeved on the connecting rod 8; multiple vibrating harvesting rods 10, vertically connected to the rotating ring 9 and evenly surrounding the axis of the rotating ring 9; a pair of support plates 1a, horizontally fixed to the top of the two connecting rods 8 respectively; four guide rods 1b, vertically fixed to the top of the support plate 1a and slidably connected to the portal frame 1; a vibrating motor 1c, fixed in the middle of the support plate 1a and located in the middle of the four guide rods 1b; and springs 1d, sleeved on the guide rods 1b and fixedly connected at both ends to the support plate 1a and the portal frame 1 respectively.

[0024] The bottom of the rectangular box 2 has a discharge port 21 that connects to its interior, and the discharge port 21 is close to one end of the screw conveyor mechanism 5; the gap between the adjacent baffles 3 is only for blueberries to pass through, the two rectangular boxes 2 and the two receiving plates 6 are symmetrically arranged in the middle of the gantry frame 1, and the upper ends of the two receiving plates 6 are close to the center of the gantry frame 1, and the lower ends of the two receiving plates 6 are close to one side of the two screw conveyor mechanisms 5 respectively.

[0025] Furthermore, the spiral conveyor mechanism 5 includes two parallel blueberry conveying troughs 51 disposed inside the rectangular box 2, two rotating shafts 52 rotatably disposed inside the rectangular box 2 and respectively parallel to the middle of the two blueberry conveying troughs 51, spiral blades 53 fixedly wound around the outer wall of the rotating shafts 52, and a rotating assembly 54 driving the two rotating shafts 52 to rotate synchronously. The bottom of the blueberry conveying trough 51 is semi-circular, the rotating shafts 52 and the semi-circular bottom of the blueberry conveying trough 51 are coaxial, and the outline of the spiral blades 53 is parallel to and close to the semi-circular bottom. The discharge port 21 penetrates the bottom of the two blueberry conveying troughs 51 and is close to one end of the blueberry conveying trough 51. By adopting the above-mentioned spiral conveyor mechanism 5, not only can blueberries be safely and stably conveyed, but also the synchronous rotation of the two rotating shafts 52 and the two spiral blades 53 in the two blueberry conveying troughs 51 can efficiently convey blueberry fruits.

[0026] Furthermore, the rotating assembly 54 includes a pair of gears 541 respectively fixed to one end of the two rotating shafts 52, a gear 542 rotatably mounted on the wall of the rectangular box 2 and meshing with the two gears 541, and a three-phase asynchronous motor 543 driving the rotating shaft 52 to rotate. Gears 541 and 542 are located at one end of the rectangular box 2 and mesh for transmission. One end of the rotating shaft 52 rotatably passes through the end wall of this end and connects to gear 541. The three-phase asynchronous motor 543 is fixedly installed at the other end of the rectangular box 2, and the other end of the rotating shaft 52 rotatably passes through the end wall of this end and connects to the output end of the three-phase asynchronous motor 543. By using the above-mentioned rotating assembly 54, not only can the two rotating shafts 52 be driven to rotate synchronously, but the gear transmission structure between the two rotating shafts 52 can also save the drive motor, reducing the manufacturing cost and energy consumption of this equipment.

[0027] Furthermore, it also includes a spiral lifting mechanism 1e, which includes a fixed rectangular box 2 bottom discharge hopper 1e1, a lifting box 1e2 fixedly connected to the outlet end of the discharge hopper 1e1 and inclined upward, a blueberry lifting trough 1e3 disposed inside the lifting box 1e2, a rotating shaft 1e4 rotatably disposed inside the lifting box 1e2 and horizontally located in the middle of the blueberry lifting trough 1e3, a spiral blade 1e5 fixedly wound around the outer wall of the rotating shaft 1e2, a three-phase asynchronous motor 1e6 driving the rotating shaft 1e4 to rotate, and a lower part opened at the bottom of the lifting box 1e2. The feed inlet 1e7 and discharge outlet 21 are located in the middle of the discharge hopper 1e1. The bottom of the blueberry lifting trough 1e3 is semi-circular. The rotating shaft 1e4 is coaxial with the semi-circular bottom of the blueberry lifting trough 1e3, and the outline of the spiral blade 1e5 is parallel and close to this semi-circular bottom. The discharge port 1e7 penetrates the bottom of the blueberry lifting trough 1e3 and is close to the upper end of the blueberry lifting trough 1e3. The three-phase asynchronous motor 1e6 is fixed to the lower end of the lifting box 1e2, and the lower end of the rotating shaft 1e4 rotates through the end wall of the lifting box 1e2 and connects to the output end of the three-phase asynchronous motor 1e6. By adopting the above-mentioned spiral lifting mechanism 1e, the blueberries delivered by the spiral conveyor 5 can be lifted to a suitable height to quickly adapt to the height of the collection trolley, mobile basket, and other collection structures following behind this equipment.

[0028] Furthermore, an elastic fabric 61 is fixedly provided between the adjacent receiving plates 6 at the top of the rectangular box 2, with both ends of the elastic fabric 61 close to the upper and lower ends of the receiving plates 6, respectively. By using the aforementioned elastic fabric 61, it is possible to prevent blueberries, leaves, twigs, and other impurities from getting stuck in the gaps between the adjacent receiving plates 6.

[0029] Furthermore, the tilt reset mechanism 7 includes a pair of support seats 71 fixed to the bottom of the receiving plate 6, a guide rod 72 fixedly connected to the two support seats 71 at both ends, a sliding sleeve 73 slidably sleeved on the guide rod 72, a connecting rod 74 hinged at both ends to the sliding sleeve 73 and the side wall of the rectangular box 2, and a spring 75 sleeved on the guide rod 72 and fixedly connected to the support seats 71 and the sliding sleeve 73 at both ends. By employing the aforementioned tilt reset mechanism 7, when blueberries fall and impact the receiving plate 6, the receiving plate 6 will flip relative to the rectangular box 2 to reduce the impact force of the blueberries and thus prevent them from breaking. At the same time, the connecting rod 74 below the receiving plate 6 flips relative to the rectangular box 2, the sliding sleeve 73 slides relative to the guide rod 72, and the spring 75 is compressed or stretched until the blueberries leave the receiving plate 6. Then, the spring 75 will immediately return to its original position, allowing the sliding sleeve 73 and the connecting rod 74 to return to their initial positions. Finally, the receiving plate 6 will flip back to its initial tilt angle position under the reset of the sliding sleeve 73 and the connecting rod 74, ready to receive subsequent blueberries.

[0030] Furthermore, a pair of U-shaped mounting plates 11 are fixedly installed on the top of the gantry frame 1. Four guide rods 1b on the two support plates 1a slide through the middle of the two U-shaped mounting plates 11 respectively. The vibration motor 1c and the spring 1d are located below the U-shaped mounting plates 11, and the upper end of the spring 1d is fixedly connected to the bottom of the U-shaped mounting plate 11. A circular limiting plate 1b1 is fixedly installed on the top of the guide rod 1b, and the outer diameter of the limiting plate 1b1 is larger than the outer diameter of the guide rod 1b. A spring 12 is also sleeved on the guide rod 1b, and the two ends of the spring 12 are fixedly connected to the limiting plate 1b1 and the U-shaped mounting plate 11 respectively. By using the U-shaped mounting plate 11, not only can the guide rod 1b be stably supported to slide up and down, but the spring 1d and spring 3 12 on the guide rod 1b can also be easily connected. By using the spring 3 12, the up and down sliding frequency of the support plate 1a, the connecting rod 8 and the rotating ring 9 can be further enhanced to ensure that the vibrating picking rod 10 can fully shake the blueberries off the blueberry tree.

[0031] Furthermore, limiting mechanisms 81 are respectively provided on the upper and lower sides of the connecting rod 8 on the rotating ring 9 to restrict the vertical sliding of the connecting rod 8 relative to it. The limiting mechanism 81 includes a limiting ring 811 sleeved on the connecting rod 8, a pair of through holes 812 opened on the outer wall of the limiting ring 811 and communicating with its interior, a pair of threaded holes 813 opened on the outer wall of the connecting rod 8 and respectively aligned with the two through holes 812, and a fixing screw 814 threaded to the threaded hole 813 and passing through the through hole 812. The outer diameter of the limiting ring 811 is larger than the inner diameter of the rotating ring 9. The upper and lower sides of the rotating ring 9 respectively contact the end faces of the limiting rings 811 in the two limiting mechanisms 81 and rotate between the two limiting rings 811. By adopting the above-mentioned limiting mechanism 81, not only can the sliding of the rotating ring 9 relative to the connecting rod 8 be restricted to maintain the height position of the rotating ring 9 and the vibrating harvesting rod 10, but the bolt fixing structure in the limiting mechanism 81 also allows the workers to install and disassemble the rotating ring 9 in order to replace the vibrating harvesting rod 10.

[0032] Furthermore, a U-shaped guardrail 22 is fixedly installed on the top of the rectangular box 2. The U-shaped guardrail is parallel to the three sides of the rectangular box 2, and all the receiving plates 6 on the top of the rectangular box 2 are located at the opening of the U-shaped guardrail. By using the above-mentioned U-shaped guardrail, blueberries can be prevented from falling outside the rectangular box 2 to a certain extent.

[0033] Furthermore, a hinge shaft 23 is fixedly installed in the middle of the U-shaped guardrail, and the hinge shaft 23 is parallel to one side of the rectangular box 2. The lower ends of all the receiving plates 6 at the top of the rectangular box 2 are rotatably connected to the hinge shaft 23. By using the aforementioned hinge shaft 23, all the receiving plates 6 can be stably supported for flipping, thus ensuring the stability of the flipping of the receiving plates 6.

[0034] The working principle of this embodiment:

[0035] When blueberries need to be harvested, first align the middle of the gantry frame 1 with one end of the blueberry bush. Then, push the traveling structure, which consists of the gantry frame 1, two rectangular boxes 2, and wheels 4, to move along the direction of the blueberry bush. After the gantry frame 1 passes over the blueberry bush, start the vibration motor 1c to vibrate the support plate 1a. The four guide rods 1b at the top of the support plate 1a slide through the U-shaped mounting plate 11. One end of the spring 1d and spring 75 fitted on the guide rod 1b are connected to the U-shaped mounting plate 11, and the other end is connected to the support plate 1a and the limiting plate 1b1 at both ends of the guide rod 1b, respectively. Therefore, under the vibration of the vibrating motor 1c, the support plate 1a will drive the connecting rod 8 connected to its bottom to slide up and down rapidly and at a high frequency relative to the gantry frame 1. Then, the rotating ring 9 sleeved on the connecting rod 8 will transmit the above vibration to the vibrating picking rod 10, causing the vibrating picking rod 10 to vibrate the branches on the blueberry tree, thereby shaking the blueberries off. Finally, the fallen blueberries will enter the rectangular box 2 through the gap between the receiving plate 6 and the baffle 3 at the opening of the rectangular box 2, and will be sent into the collection cart following behind the equipment by the screw conveyor mechanism 5 and the screw lifting mechanism 1e. Because of their large length and volume, most of the fallen leaves and branches are blocked by the baffle 3 at the entrance of the rectangular box 2 before the blueberries enter. This method easily separates the impurities such as fallen leaves and branches from the blueberries. At the same time, the spiral conveying mechanism 5 and the spiral elevator are not easily jammed by impurities such as fallen leaves and branches, so the process of conveying blueberries is stable and safe.
