[0002] In recent years, third-generation fruits have gradually become more widely available. These refer to wild, uncultivated wild fruits found in barren mountainous forests, as well as newly discovered, high-quality fruits. Simply put, these wild, highly nutritious fruits possess pharmacological properties, acting as both medicine and food. Demand for these fruits is enormous in the international market, and they hold a promising future.

[0034] The preferred embodiments of the present disclosure are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0035] See also Figures 1 to 7 As shown, the present invention provides a traction-type berry harvester, comprising: a frame 1, the frame 1 being a door-type structure, a walking mechanism 2 being provided at the bottom of the frame 1; a conveying mechanism being provided on the frame 1, the conveying mechanism comprising two middle conveyors 3 located in the frame 1 and side conveyors 5 provided on both sides of the frame 1; a seedling-supporting mechanism 6 being provided at one end of the middle conveyor 3; a supporting structure 7 having two parts and staggered, the middle conveyor 3 being provided on the supporting structure 7, the supporting structure 7 being inclined with respect to the frame 1, and a vibration mechanism 60 being provided on the supporting structure 7; a traction mechanism 8, is provided at one end of the frame 1, the traction mechanism 8 includes a traction frame 9 and a fixed frame 10, and a hydraulic oil pump 11, the traction frame 9 is connected to the frame 1, the fixed frame 10 is connected to the traction frame 9, and the hydraulic oil pump 11 is provided on the fixed frame 10; the hydraulic mechanism 12, an oil tank 13 is provided in the hydraulic mechanism 12, the oil tank 13 is connected to the hydraulic oil pump 11, and the hydraulic oil pump 11 is connected to the conveying mechanism and the vibration mechanism 60; the harvesting basket 14 is provided at one end of the frame 1 away from the traction mechanism 8, and the harvesting basket 14 is provided corresponding to the side conveyor 5.

[0036] By installing a traction mechanism 8 at the end of the frame 1, which includes a traction frame 9 and a fixed frame 10, as well as a hydraulic oil pump 11 installed on the fixed frame 10, the traction frame 9 is used to connect the frame 1 to the tractor, thereby driving the frame 1 to perform harvesting. At the same time, the frame 1 has a door-like structure, which facilitates the passage of fruit seedlings through the middle of the frame 1. The top crossbeam is welded to form the left and right parts into a whole to ensure overall stability. Meanwhile, a support structure 7 is provided within the gap of the portal structure. Two support structures 7 are positioned on either side of the portal structure, and are staggered to prevent interference. A central conveyor 3 is mounted on the support structure 7. This central conveyor 3 cooperates with a seedling support mechanism 6 to straighten fallen seedlings. A vibration mechanism 60, mounted on the support structure 7, vibrates the fruit from the seedlings. Through the vibration and slow rotation of the vibration system, the fruit is vibrated onto the central conveyor 3. The two central conveyors 3 then transport the fruit to the side conveyors 5, which ultimately transport the fruit to the harvesting basket 14 for harvesting. Throughout this process, the operator simply stands at the operating console at the rear of the harvester and replaces the harvesting basket 14 when it is about to be filled with fruit. This results in an efficient and integrated harvesting process. According to rough estimates, one berry harvester can handle the workload of 50 people. The setting of the towed berry harvester realizes mechanical picking, can collect and remove impurities from the fruit seedlings, and has high picking efficiency, and can be towed to industrial scale.

[0037] Among them, a hydraulic oil tank 13 is also provided on the end cross beam of the frame 1, and the hydraulic mechanism 12 includes an oil tank 13 and an oil pipe connected to the oil tank 13, and a valve body for the circulation of hydraulic oil is provided on the oil pipe; the oil pipe is connected to the hydraulic oil pump 11, and the hydraulic oil in the hydraulic oil tank 13 is transported to the vibration mechanism 60, the middle conveyor 3 and the side conveyor 5 through the hydraulic oil pump 11, thereby driving the vibration machine 60, the middle conveying mechanism 3 and the side conveying mechanism 5 to operate.

[0038] In some optional embodiments, the middle conveyor 3 includes a fixed plate 4 and a first transmission shaft 15, and a first transmission belt 16; wherein, there are two fixed plates 4, the two fixed plates 4 are fixedly connected to the support structure 7, and two first transmission shafts 15 are provided between the fixed plates 4; the first transmission belt 16 is sleeved on the first transmission shaft 15; the middle motor (not shown in the figure) is provided in the fixed plate 4, and the middle motor is connected to the first transmission shaft 15 and the hydraulic oil pump 11.

[0039] It is connected to the middle motor through a hydraulic oil pump 11 and an oil pipe, thereby providing hydraulic oil to the middle motor; at the same time, driven by the middle motor, it drives a first transmission shaft 15 to rotate, and then drives another first transmission shaft 15 to rotate through a first transmission belt 16, thereby transporting the fruit from the middle conveyor to the side conveyor 5 for further transportation.

[0040] The fixing plate 4 is fixed to the supporting structure 7 by bolts, thereby achieving a fixed connection between the middle conveyor 3 and the supporting structure 7 and ensuring that the middle conveyor 3 is stably installed on the supporting structure 7 and the frame 1 .

[0041] In some optional embodiments, the side conveyor 5 includes a frame 17, a second transmission shaft 18, a second transmission belt 19, and a side motor; wherein the frame 17 is provided on both sides of the frame 1 and is fixedly connected to the frame 1, two second transmission shafts 18 are provided in the frame 17; the second transmission belt 19 is sleeved on the second transmission shaft 18; a side motor (not shown in the figure) is provided in the frame 17, and the side motor is connected to the second transmission shaft 18 and the hydraulic oil pump 11. The hydraulic oil pump 11 and the oil pipe are connected to the side motor to provide hydraulic oil to the side motor; at the same time, driven by the side motor, one second transmission shaft 18 is driven to rotate, and then the other second transmission shaft 18 is driven to rotate through the second transmission belt 19, thereby transporting the fruit from the side conveyor 5 to the harvesting basket 14 for collection.

[0042] The middle motor and the side motors are hydraulic motors.

[0043] The frame 17 is fixed to the support structure 7 by bolts, thereby achieving a fixed connection between the side conveyor 5 and the support structure 7 and ensuring that the side conveyor 5 is stably installed on the support structure 7 and the frame 1.

[0044] In this embodiment, due to the length of the frame 1, the number of fruit seedlings to be harvested also increases; therefore, the frame 17 includes a first section 20 and a second section 21. The second section 21 is arranged at an angle relative to the first section 20 and is located above the traveling mechanism 2. The end of the frame 17 in the second section 21 is located above the harvesting basket 14, allowing the fruit transported by the side conveyor 5 to be directly transferred to the harvesting basket 14 for collection, thus achieving automatic harvesting of the towed berry harvester.

[0045] In some optional embodiments, the towed berry harvester further includes a seedling pressing mechanism 22, which includes a fixed rod 23 and a bent pipe 24; wherein the fixed rod 23 is arranged at one end of the frame 1 and is arranged perpendicular to the frame 1; there are multiple bent pipes 24, which are respectively arranged at intervals along the extension direction of the fixed rod 23, one end of the bent pipe 24 is connected to the fixed rod 23, and the other end is a free end, and the free end extends into the vibration mechanism 60.

[0046] The fixing rod 23 is welded to the crossbeam at the upper front end of the frame 1. The curved pipes 24 are arranged symmetrically with respect to the fixing rod 23. Each curved pipe 24 is fixed to the support structure 7 by a binding method. One end of the curved pipe 24 is connected to the fixing rod 23 by a pin, and the other end extends to the rear of the harvester. When viewed from the front of the vehicle, the seedling pressing mechanism 22 is shaped like a "boat". The function of the seedling pressing mechanism 22 is to separate the fruit seedlings to the sides and position the fruit seedlings between the curved pipes 24 and the middle conveyor 3. At this time, the toggle rod 54 of the vibration mechanism 60 is most effective in vibrating and harvesting the fruit seedlings.

[0047] In this embodiment, the elbow 24 is a plastic tube.

[0048] The seedling support mechanism 6 consists of two seedling support plates 25, which are respectively arranged on the support structure 7 and are oriented in the same direction as the frame 1. One end of the seedling support plate 25 is fixed to the support structure 7 by a hinge, and the other end is close to the ground. The seedling support plate 25 is bent to facilitate gradually raising the fruit tree that has fallen on the ground.

[0049] The wheel mechanism 26 comprises two wheels 26 at the rear of the frame 1 and a universal wheel 27 at the front of the frame 1. Since the tractor-type berry harvester is a traction-type berry harvester, one side of the front of the frame 1 is provided with the traction mechanism 8 and the other side is provided with the universal wheel 27. When a tractor is pulling the frame 1, the universal wheel 27 can realize the steering of the frame 1.

[0050] In some optional embodiments, the vibration mechanism 60 includes: a driving mechanism 28, connected to a reversing gear box 29, and the reversing gear box 29 is connected to a reducer 30; a swing box 31, provided with a driving shaft 32 and two driven shafts 33, the driving shaft 32 passes through the swing box 31, the driving shaft 32 is connected to the reversing gear box 29, and the driven shafts 33 are located on both sides of the driving shaft 32; a double-row sprocket 34, provided at one end of the driving shaft 32, and the double-row sprocket 3 4 is connected to the reversing gear box 29 through a coupling; a driving wheel 35 and a driven wheel 36, the driving wheel 35 is provided on the driving shaft 32, and the driven wheel 36 is provided on the driven shaft 33; a connecting chain 37 is provided on the driving wheel 35 and the driven wheel 36, and the connecting chain 37 is used to drive the driven shaft 33 to rotate; an inertia hammer 38 is provided on the driven shaft 33, and the inertia hammer 38 rotates around the driven shaft 33; a toggle assembly 39 is connected to the driving shaft 32.

[0051] A driving shaft 32 and a driven shaft 33 are provided in the swing box 31 , and the driving shaft 32 passes through the swing box 31 and is connected to the shifting assembly 39 and the reversing gear box 29 . Among them, the reversing gear box 29 is connected to the reducer 30 and the driving mechanism 28, so that the driving shaft 32 is provided with a power source through the driving mechanism 28; at the same time, two driven shafts 33 are arranged on both sides of the driving shaft 32, and a driving wheel 35 is provided on the driving shaft 32, and a driven wheel 36 is provided on the driven shaft 33, and the driving shaft 32 and the driven shaft 33 are connected by a connecting chain 37, so that when the driving mechanism 28 drives the driving shaft 32 to rotate, the connecting chain drives the driven shaft 33 to be connected with the driving shaft 32, thereby driving the driven shaft 33 to rotate; since an inertia hammer 38 is provided on the driven shaft 33, when the driven shaft 33 rotates, the inertia hammer 38 is also driven to rotate, and the rotation of the inertia hammer 38 is relative rotation. According to the inertia of the swing of the inertia hammer 38, the swing box 31 vibrates; due to the power transmitted to the double-row sprocket 34 by the connecting chain 37, the swing box 31 will vibrate back and forth while having a slower rotation effect. The slower rotation allows the swing box 31 to turn the saplings away, i.e. without colliding with the saplings, so that only berries are harvested.

[0052] The structure of the berry harvesting vibration generator is relatively simple. The drive mechanism 28 drives the reversing gearbox 29, which in turn drives the driving shaft 32 and the driven shaft 33. The inertia of the swinging inertia hammer 38 causes the swing box 31 to vibrate. The paddle assembly 39 contacts the small berry plants, causing the small berry plants to vibrate to a certain amplitude. When the amplitude reaches a certain level, the small berry fruits are separated from the plants, thereby achieving the purpose of collecting the fruits. Because the power output by the drive mechanism 28 is a stable force, the force applied to the reversing gearbox 29, the driving shaft 32, the driven shaft 33, and the inertia hammer 38 is stable. Therefore, the picking force of the berry harvesting vibration generator can be stably guaranteed, thereby improving the fruit picking rate of the berry harvesting vibration generator and thereby improving the picking efficiency.

[0053] In this embodiment, the driving mechanism 28 is a hydraulic motor, and the reducer 30 is a worm gear reducer 30 .

[0054] The hydraulic oil pump 11 is connected to the driving mechanism 28 of the vibration mechanism 60 to provide hydraulic oil to the driving mechanism 28 .

[0055] In some optional embodiments, the driving wheel 35 includes a first row of wheel bodies 40 and a second row of wheel bodies 41. By setting the driving wheel 35 as two rows of wheel bodies, namely, including the first row of wheel bodies 40 and the second row of wheel bodies 41, one of the driven wheels 36 is located on the same straight line as the first row of wheel bodies 40, and the other driven wheel 36 is located on the same straight line as the second row of wheel bodies 41, so that the driving wheel 35 drives the two driven wheels 36 to rotate, that is, the two driven shafts 33 are driven to rotate through the driving shaft 32, thereby realizing the linkage between the driving shaft 32 and the two driven shafts 33.

[0056] In some optional embodiments, the berry harvesting vibration generating device further includes a limiting shaft 42 and a limiting baffle 44; wherein, one end of the limiting shaft 42 is connected to the double-row sprocket 34, and the end of the limiting shaft 42 away from the double-row sprocket 34 is provided with a limiting rubber pier 43; the limiting baffle 44 is provided on the swing box 31, and there is a gap between the limiting baffle 44 and the limiting rubber pier 43.

[0057] During actual use, when the swing box 31 vibrates, the limit baffle 44 on the swing box 31 will collide with the limit rubber step. At the same time, due to the power transmitted to the double-row sprocket 34 by the connecting chain 37, the swing box 31 will produce the effect of vibrating back and forth while rotating slowly.

[0058] In some optional embodiments, the berry harvesting vibration generating device further includes a mounting plate 45, wherein the mounting plate 45 is disposed on the driven shaft 33, and the inertia hammer 38 is disposed on the mounting plate 45; wherein the two mounting plates 45 are disposed 180° in opposite directions; the mounting plate 45 is mounted on the driven shaft 33 by means of bolts, and the inertia hammer 38 can be mounted on the driven shaft 33 through the setting of the mounting plate 45.

[0059] In some optional embodiments, the berry harvesting vibration generating device further includes bearing blocks 46, which are disposed at both ends of the driving shaft 32 and the driven shaft 33 and are connected to the inner wall of the swing box 31. The provision of bearing blocks 46 at both ends of the driving shaft 32 and the driven shaft 33 ensures smooth rotation of the driving shaft 32, the driven shaft 33, and the swing box 31, preventing interference or jamming between the driving shaft 32, the driven shaft 33, and the inner wall of the swing box 31.

[0060] Since there is one driving shaft 32 and two driven shafts 33 , six bearing seats 46 are required.

[0061] In some optional embodiments, the berry harvesting vibration generating device further includes a positioning sleeve 47, which is disposed between the bearing seat 46 and the driving shaft 32 and the driven shaft 33. The positioning sleeve 47 is disposed to achieve precise positioning of the bearing seat 46 and the driving shaft 32 and the driven shaft 33.

[0062] In some optional embodiments, the swing box 31 includes a partition 48, which is used to separate the swing box 31 and divide it into a first cavity 49 and a second cavity 50. The driving wheel 35, the driven wheel 36, and the connecting chain 37 are disposed in the first cavity 49, and the inertia hammer 38 and the mounting plate 45 are disposed in the second cavity 50.
