A raspberry fruit harvesting device

Abstract

This invention discloses a raspberry fruit harvesting device, which includes a collection box and wheels. A harvesting mechanism for harvesting raspberries is located at the top of the collection box. The harvesting mechanism includes a rotating shaft with multiple striking rods fixedly mounted on its outer surface. A motor is fixedly mounted inside the top of a supporting frame, driving the rotating shaft to reciprocate vertically within the supporting frame. During harvesting, the striking rods on the harvesting mechanism extend into the raspberry tree. Simultaneously, the rotating shaft, driven by the motor, reciprocates vertically within the supporting frame, causing the striking rods on the rotating shaft to reciprocate within the raspberry tree, striking the branches and fruits. Ripe fruits detach from the branches and fall due to the shaking of the tree and the striking of the rods, while unripe fruits, due to their strong connection to the branches, are retained and harvested later when ripe.

Description

[0002] Raspberry is a woody plant belonging to the genus Rubus in the family Rosaceae. Raspberry plants have medicinal uses and various medicinal values. Its fruit is an aggregate fruit, composed of many small drupes, which is conical or flattened conical in shape, light in weight, hard in texture, has a faint odor, and a slightly sour and astringent taste. Currently, raspberry harvesting mainly relies on two methods: manual harvesting and machine harvesting. After long hours of harvesting, workers are under heavy load, resulting in low harvesting efficiency. When using machines for harvesting, the machines cannot distinguish the ripeness of the fruit and pick unripe fruits as well, leading to a decrease in raspberry fruit yield. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a raspberry fruit harvesting device.

[0026] Please see Figure 1-5 In this embodiment, the raspberry fruit harvesting device includes a collection box 1 and moving wheels 2. The top of the collection box 1 is provided with a harvesting mechanism 3 for harvesting raspberry fruits. The harvesting mechanism 3 includes a support frame 31 fixedly installed at the top of the collection box 1. The bottom end of the support frame 31 is provided with a harvesting groove 32. A rotating shaft 33 is rotatably installed inside the harvesting groove 32. Multiple striking rods 34 are fixedly installed on the outer surface of the rotating shaft 33. A motor 39 is fixedly installed inside the top of the support frame 31, which reciprocates vertically within the support frame 31 by driving the rotating shaft 33.

[0027] When harvesting raspberries, the collection box 1 and the harvesting mechanism 3 are driven by the moving wheel 2, so that the striking rod 34 on the harvesting mechanism 3 extends into the raspberry tree. At the same time, the rotating shaft 33 can reciprocate vertically within the support frame 31 under the drive of the motor 39, which in turn drives the striking rod 34 on the rotating shaft 33 to reciprocate in the raspberry tree, striking the branches and fruits. At this time, the ripe fruits will detach from the branches and fall down with the shaking of the fruit tree and the striking of the striking rod 34, while the unripe fruits will be retained because of their strong connection with the branches, waiting to be harvested in the next harvesting process after ripening.

[0028] Optionally, the striking rods 34 are evenly distributed at equal intervals on the surface of the rotating shaft 33.

[0029] It should be noted that this embodiment does not limit the connection method between the transmission shaft 33, the motor 39, and the support gantry 31. Regardless of the structure and connection method, as long as the transmission shaft 33 can reciprocate vertically within the support gantry 31 under the drive of the motor 39, it should be within the protection scope of this invention. Of course, a specific connection method between the transmission shaft 33, the motor 39, and the support gantry 31 can be designed, as detailed below:

[0030] Specifically, a turntable 310 is fixedly installed at the output end of motor 39, an eccentric shaft 314 is fixedly installed on one side of the turntable 310, a shaft fork 312 is rotatably installed at the top of the shaft 33, a connecting rod 313 is rotatably installed inside the shaft fork 312, and the end of the connecting rod 313 away from the shaft fork 312 is rotatably connected to the eccentric shaft 314.

[0031] The above causes the output of motor 39 to drive turntable 310 to rotate, turntable 310 to drive eccentric shaft 314 to rotate, so that eccentric shaft 314 and turntable 310 make eccentric motion with eccentric shaft 314 and turntable 310 as the center. At this time, eccentric shaft 314 rises with the rotation of turntable 310. Eccentric shaft 314 pulls shaft fork 312 to rise through connecting rod 313. Shaft fork 312 drives shaft 33 and striking rod 34 to rise. As turntable 310 continues to rotate, motor 39 can realize the transmission shaft 33 to reciprocate in the vertical direction within the support frame 31, thereby driving striking rod 34 to shake off ripe fruits while retaining unripe fruits.

[0032] In the above embodiments, the connection method between the rotating shaft 33 and the supporting gantry 31 can be further designed:

[0033] Specifically, the top of the supporting gantry 31 has a second slide groove 311, the inside of the second slide groove 311 has rifling, the top of the rotating shaft 33 is slidably connected to the second slide groove 311, and the top of the rotating shaft 33 has a slider adapted to the rifling.

[0034] When the rotating shaft 33 moves up and down with the eccentric shaft 314, the rotating shaft 33 moves up and down repeatedly along the slide groove 311. At this time, when the picking device moves on the picking path, the rotating shaft 33 will be subjected to force in the horizontal direction. At this time, the slider at the top of the rotating shaft 33 can slide along the rifling inside the slide groove 311, so that the rotating shaft 33 rotates inside the slide groove 311. At the same time, the rotating shaft 33 drives the striking rod 34 to rotate, making it easier for the picking device to advance on the path, while reducing the pulling of the striking rod 34 on the fruit tree, thus protecting the fruit tree.

[0035] It is understandable that in the above embodiment, the rotating shaft 33 can only actively vibrate in the vertical direction. Although the rotating shaft 33 can also rotate in the horizontal direction, it is a passive rotation and therefore cannot help to harvest the fruit. Therefore, the rotating shaft 33 can be further specifically designed, as detailed below:

[0036] Specifically, a groove 35 is provided inside the bottom end of the rotating shaft 33. A guide rod 36 is slidably arranged inside the groove 35 and is fixedly connected to the collection box 1. A piston plate 37 is fixedly arranged at the top end of the guide rod 36. An air outlet 38 is provided at the bottom end of the rotating shaft 33 and is connected to the groove 35. Optionally, there may be one air outlet 38, which is arc-shaped. Preferably, there may be two or more air outlets 38, which are arc-shaped and arranged in a clockwise or counterclockwise direction.

[0037] When the rotating shaft 33 moves upward, the guide rod 36 slides inside the groove 35, making the rotating shaft 33 more stable during movement. Simultaneously, the piston plate 37 compresses the air inside the groove 35, causing it to escape through the air outlet 38. This expelled air exerts a reaction force on the rotating shaft 33, generating a torsional force in the horizontal direction, causing it to reciprocate. This, in turn, drives the striking rod 34 to strike the branches and fruits horizontally. At this time, the ripe fruits are simultaneously shaken in both the vertical and horizontal directions, making them easier to detach from the branches and fall, thus improving harvesting efficiency. Furthermore, during harvesting, leaves and fruits are often shaken into the harvesting trough 32. The air expelled through the air outlet 38 blows these leaves and fruits out from the bottom of the harvesting trough 32, preventing the accumulation of branches, leaves, and fruits that could affect the normal operation of the harvesting mechanism 3 and improving machine stability.

[0038] Please refer to further information. Figure 6In the above embodiments, a screening mechanism 4 can also be designed. The collection box 1 is equipped with a screening mechanism 4 for screening raspberry fruits. The screening mechanism 4 also includes a fruit-catching component 43 to prevent raspberry fruits from falling. Multiple fruit-catching components 43 include a second rotating shaft 431 rotatably mounted at the top of the collection box 1. The second rotating shaft 431 is located at the edge of the collection opening 42. A fan-shaped plate 432 is fixedly mounted at the bottom of the second rotating shaft 431, and multiple fan-shaped plates 432 are stacked and pressed together. A buffer bead 434, made of silicone, is fixedly mounted at the top of the fan-shaped plate 432. A torsion spring 433 is sleeved on the outside of the second rotating shaft 431, and both ends of the torsion spring 433 are fixedly connected to the collection box 1 and the fan-shaped plate 432, respectively. Preferably, the fan-shaped plate 432 is inclined from high to low towards the collection opening 42.

[0039] When the collection box 1 moves near the raspberry plant, the raspberry plant presses against the fan-shaped plate 432, causing the fan-shaped plate 432 to drive the rotating shaft 431 to rotate. At the same time, the fan-shaped plate 432 twists the torsion spring 433. At this time, the fan-shaped plate 432 is in contact with the surface of the raspberry plant, making it easy to catch the falling fruit. When the fruit falls, it first touches the buffer bead 434. Since the buffer bead 434 is made of silicone, it prevents the fruit from falling directly onto the fan-shaped plate 432 and causing damage. At the same time, because the fan-shaped plate 432 is tilted towards the collection port 42, the fruit will naturally roll to the collection port 42. In addition, when some fruits accumulate on the fan-shaped plate 432, due to the overlapping and compression of the fan-shaped plates 432, when the collection box 1 moves, the fan-shaped plate 432 located at the front upper part will push the fruits accumulated on the surface of the fan-shaped plate 432 located at the rear lower part, so that the fruits enter the interior of the collection box 1 through the collection port 42, which is conducive to the collection of fruits. When there are no raspberry plants at the front of the travel route, the torsion spring 433 rebounds and drives the fan-shaped plate 432 back to the initial position, so that the fan-shaped plate 432 remains in a close fit.

[0040] In the above embodiments, the screening mechanism 4 can be further designed:

[0041] Specifically, a sieve plate 44 is fixedly installed inside the collection box 1, and multiple sieve holes 45 are opened inside the sieve plate 44. A power distribution box 46 is fixedly installed on the side of the collection box 1 away from the waste outlet 41, and a central control plate 47 is fixedly installed on the outside of the power distribution box 46.

[0042] Fruits entering the collection box 1 through the collection port 42 will fall onto the surface of the sieve plate 44. Fruits with a diameter smaller than the sieve hole 45 will fall onto the surface of the conveyor belt 56 through the sieve hole 45. Conversely, fruits with a diameter larger than the sieve hole 45 will remain on the surface of the sieve plate 44. This facilitates the classification and screening of fruits and saves manpower. The central control board 47 is electrically connected to motor 3 52, motor 1 39, and motor 2 481, which facilitates the control of the picking process by the staff.

[0043] In the above embodiments, the screening mechanism 4 can be further specifically designed:

[0044] Specifically, the screening mechanism 4 also includes a cleaning component 48 for cleaning the collected branches and leaves. The cleaning component 48 includes a second motor 481 fixedly installed inside the distribution box 46. A first gear 482 is fixedly installed at the output end of the second motor 481. A reciprocating screw 483 is rotatably installed inside the collection box 1 and passes through the collection box 1 and the distribution box 46. A second gear 484 is fixedly installed at one end of the reciprocating screw 483 inside the distribution box 46. The second gear 484 meshes with the first gear 482. A scraper 485 is slidably installed inside the collection box 1 and the bottom end of the scraper 485 is pressed and connected to the sieve plate 44. The scraper 485 is screwed to the reciprocating screw 483. A fruit drop opening 49 is opened inside the sieve plate 44 near the waste outlet 41. A fruit storage box 410 is detachably installed at the end of the collection box 1 near the waste outlet 41 and is located below the fruit drop opening 49.

[0045] When fruit remains on the surface of the sieve plate 44, the second motor 481 is started. The output end of the second motor 481 drives the first gear 482 to rotate. At the same time, the first gear 482 drives the reciprocating screw 483 to rotate through the meshing gear 484. At this time, the scraper 485 moves back and forth along the reciprocating screw 483. The scraper 485 squeezes the fruit remaining on the surface of the sieve plate 44 and moves it towards the fruit drop opening 49. At this time, the fruit will fall into the interior of the first fruit storage box 410 through the fruit drop opening 49, which is convenient for collecting large fruits. After the fruit falls into the first fruit storage box 410, since the size of the branches and leaves is larger than the fruit drop opening 49, the scraper 485 continues to squeeze and drive the branches and leaves forward, so that the branches and leaves are discharged through the waste outlet 41, which is convenient for cleaning the branches and leaves, reducing the workload of cleaning the collected fruits later and improving work efficiency. When the first fruit storage box 410 is full of fruits, the first fruit storage box 410 is taken out from the inside of one side of the collection box 1 for easy transportation of fruits.

[0046] Please refer to further information. Figure 7-8 In the above embodiments, a conveying mechanism 5 can also be designed.

[0047] Specifically, the collection box 1 is equipped with a conveying mechanism 5 for classifying and collecting raspberry fruits. The conveying mechanism 5 includes a second fruit storage box 51 detachably installed at the end of the collection box 1 away from the waste outlet 41. A third motor 52 is fixedly installed on the side of the collection box 1 away from the fan-shaped plate 432. A first drive shaft 53 is fixedly installed at the output end of the third motor 52 and passes through the collection box 1. A second drive shaft 54 ​​is rotatably installed inside the collection box 1 and passes through the collection box 1. The same drive belt 55 is sleeved on the outer end of the second drive shaft 54 ​​and the first drive shaft 53. The same conveyor belt 56 is sleeved on the outer surface of the second drive shaft 54 ​​and the first drive shaft 53 inside the collection box 1. The conveyor belt 56 is located below the sieve plate 44, and the end of the conveyor belt 56 near the second drive shaft 54 ​​is located above the second fruit storage box 51.

[0048] When the fruit falls onto the surface of the conveyor belt 56, the motor 3 52 is started. The output end of the motor 3 52 drives the drive shaft 1 53 to rotate. The drive shaft 1 53 drives the drive shaft 2 54 to rotate synchronously through the drive belt 55. At this time, the conveyor belt 56 rotates synchronously with the drive shaft 1 53 and the drive shaft 2 54. The drive belt 55 improves the stability of the conveyor belt 56 when it rotates. The conveyor belt 56 moves the fruit that has fallen on the surface, so that the fruit falls into the interior of the fruit storage box 2 51, which is convenient for collecting the fruit, improving the automation level of the device and saving manpower. When the fruit storage box 2 51 is full of fruit, the fruit storage box 2 51 is removed from one side of the collection box 1 for easy transportation of the fruit.

[0049] In any of the above technical solutions, the collection box 1, the moving wheel 2, the picking mechanism 3, the screening mechanism 4, and the conveying mechanism 5 can also be symmetrically arranged into two groups.
