Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical tree vibration technology, specifically a deployable support tree shaking vehicle. Background Technology
[0002] In fruit harvesting, mechanical vibration tree harvesting is widely used for walnut and camellia fruit harvesting. However, traditional mechanical vibration harvesters have a simple structure and simply use a vibrator for mechanical vibration harvesting. The harvesting is too violent and often results in excessive oscillation amplitude, causing damage to the trunk and roots, which has an adverse effect on the sustainable high-yield harvest of the product. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an unfoldable support tree shaking cart to overcome the shortcomings of the prior art. This unfoldable support tree shaking cart clamps the tree trunk and supports it on the ground through a support joint assembly mechanism. When the vibrating clamp shakes the tree trunk to pick the fruit, the support joint assembly mechanism stabilizes the lower part of the tree trunk (the part of the tree trunk located below the part of the support joint assembly mechanism that clamps the tree trunk) to protect the tree trunk and roots. At the same time, the vibrating clamp is suspended on the rotating body of the cart to reduce the resonance of the cart body, which can effectively promote the fruit to fall off and reduce damage to the tree trunk.
[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0008] The supporting joint assembly mechanism is located below the vibrating clamp. The supporting joint assembly mechanism includes a clamping base plate, a joint driving mechanism, a left supporting joint, and a right supporting joint. The clamping base plate is connected to the rotating body of the vehicle. The tops of the left supporting joint and the right supporting joint are rotatably connected to the clamping base plate.

One end of the push rod of the left hydraulic cylinder is provided with a left ring block. The inner cavity of the left ring block is rotatably connected to the convex ball on the left variable angle ball through a ball connection.

[0016] The right auxiliary rod drive mechanism adopts a right hydraulic cylinder. The cylinder body of the right hydraulic cylinder is fixedly connected to the right side of the inclined joint.

[0022] The beneficial effects of this utility model are as follows:
[0023] This utility model features an unfoldable support tree-shaking cart. First, a hydraulic cylinder pushes the left and right support joints to tightly embrace the tree trunk. Then, multiple directional support plates within the left and right support joints are pushed to the ground, surrounding and stabilizing the trunk. When shaking the trunk to harvest fruit, the left and right support joints continue to embrace and stabilize the trunk, reducing swaying of the lower trunk and roots, protecting them, and minimizing damage. The vibrating clamps, suspended from the cart body by flexible ropes, are located above the left and right support joints. A hydraulic cylinder pushes the vibrating clamps to grip the trunk, activating the polarizer within the large clamp body to shake the trunk and harvest the fruit. This suspension method reduces vehicle body resonance, effectively promoting fruit drop and minimizing trunk damage. Attached Figure Description

[0033] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:
[0034] like Figure 1-2As shown, a deployable tree-shaking support vehicle includes a vehicle body 1, a rotating body 2, a turntable 3, a support joint assembly mechanism 4, and a vibrating clamp 5. The vehicle body 1 is connected to the rotating body 2 via the turntable 3, which drives the rotating body 2 to rotate.
[0035] The top of the rotating body 2 is connected by a suspension device, which is used to clamp the tree trunk and perform oscillation.
[0036] like Figure 2 As shown, the supporting joint assembly mechanism 4 is located below the vibrating clamp 5. The supporting joint assembly mechanism 4 includes a clamping base plate 401, a joint driving mechanism 402, a left supporting joint, and a right supporting joint. The clamping base plate 401 is fixedly connected to the rotating body 2. The tops of the left supporting joint and the right supporting joint are rotatably connected to the clamping base plate 401. The clamping base plate 401 is provided with a joint driving mechanism 402. The joint driving mechanism 402 is used to drive the tops of the left supporting joint and the tops of the right supporting joint to approach and separate, thereby realizing that the tops of the left supporting joint and the tops of the right supporting joint clamp the tree trunk and release the tree trunk.
[0037] like Figure 2 As shown, the left and right support joints have the same structure and are symmetrically arranged. Each includes a clamping support block 403, an oblique joint 404, a left auxiliary rod 405 located to the left of the oblique joint 404, and a right auxiliary rod 406 located to the right of the oblique joint 404. The top of the oblique joint 404 is welded and fixedly connected to the clamping support block 403. The tops of the left auxiliary rod 405 and the right auxiliary rod 406 are respectively rotatably connected to the clamping support block 403. The oblique joint 404 is provided with a left auxiliary rod drive mechanism 407 for pushing the left auxiliary rod 405 away from itself and a right auxiliary rod drive mechanism 408 for pushing the right auxiliary rod 406 away from itself. Each of the oblique joint 404, the left auxiliary rod 405, and the right auxiliary rod 406 is provided with a support drive mechanism 409. The output end of the support drive mechanism 409 is rotatably connected to the deflection support plate 410. The support drive mechanism 409 is used to drive the deflection support plate 410 to move towards the ground until the deflection support plate 410 is in close contact with the ground.
[0038] The turntable 3 is an automatic rotating disc. The automatic rotating disc includes a motor and a turntable. The motor in the turntable 3 is located in the vehicle body 1 and can control the turntable 3 to adjust its angle, thereby adjusting the orientation of the vehicle body 2.
[0039] like Figure 5As shown, the joint drive mechanism 402 includes a clamping engagement pushing hydraulic cylinder 4021, a left clamping crank 4022, a right clamping crank 4023, and a clamping push plate 4024. The clamping engagement pushing hydraulic cylinder 4021 is fixedly connected to the upper surface of the clamping base plate 401. The clamping push plate 4024 is slidably connected to the pushing channel on the clamping base plate 401. The middle part of the left clamping crank 4022 is rotatably connected to the left front side of the clamping base plate 401. The middle part of the right clamping crank 4023 is rotatably connected to the right front side of the clamping base plate 401. The outer front end of the left clamping crank 4022 is welded and fixedly connected to the clamping support block 403 of the left support joint. The outer front end of the right clamping crank 4023 is welded and fixedly connected to the clamping support block 403 of the right support joint.
[0040] like Figure 7 As shown, the clamping push plate 4024 has a left inclined surface 4024A on the left side and a right inclined surface 4024B on the right side. When the clamping engagement hydraulic cylinder 4021 pushes the clamping push plate 4024 forward, the left inclined surface 4024A of the clamping push plate 4024 moves forward, thereby pushing the rear end of the left clamping bend 4022 to rotate outward, and the right inclined surface 4024B of the clamping push plate 4024 moves forward, thereby pushing the rear end of the right clamping bend 4023 to rotate outward. Finally, the front ends of the left clamping bend 4022 and the front ends of the right clamping bend 4023 both rotate inward, and finally the inner wall of the clamping support block 403 of the left support joint and the inner wall of the clamping support block 403 of the right support joint clamp the tree trunk. When the clamping engagement hydraulic cylinder 4021 drives the clamping push plate 4024 to move backward, the left inclined surface 4024A and the right inclined surface 4024B of the clamping push plate 4024 move away from the rear end of the left clamping bend 4022 and the rear end of the right clamping bend 4023, respectively. The front end of the left clamping bend 4022 and the front end of the right clamping bend 4023 no longer have the inward rotating thrust, and the clamping support block 403 of the left support joint and the clamping support block 403 of the right support joint no longer have the force to clamp the tree trunk, that is, the tree trunk is released.
[0041] like Figure 8As shown, the clamping push plate 4024 includes a central strip plate 40241, a left inclined plate 40242, a left grooved plate 40243, a right inclined plate 40244, and a right grooved plate 40245. The left inclined plate 40242 and the right inclined plate 40244 are fixedly connected to both sides of the central strip plate 40241, respectively. The left inclined plate 40242 and the right inclined plate 40244 are symmetrically arranged, with the left inclined plate 40242 close to the left clamping bend 4022. One side is a left inclined surface 4024A, and the side of the right inclined plate 40244 near the right clamping bend 4023 is a right inclined surface 4024B. A left grooved plate 40243 is fixedly connected to the end of the left inclined plate 40242 away from the central strip plate 40241, and a right grooved plate 40245 is fixedly connected to the end of the right inclined plate 40244 away from the central strip plate 40241. The left grooved plate 40243 and the right grooved plate 40245 are symmetrically arranged. The groove opening of the left grooved plate 40243 faces the rear end of the left clamping bend 4022, and the groove opening of the right grooved plate 40245 faces the rear end of the right clamping bend 4023.
[0042] When the clamping engagement hydraulic cylinder 4021 pushes the clamping push plate 4024 forward along the push channel on the clamping base plate 401, the rear end of the left clamping crank 4022 rotates outward under the action of the left inclined surface 4024A of the clamping push plate 4024 (that is, the rear end of the left clamping crank 4022 moves along the left inclined surface 4024A of the clamping push plate 4024), thereby causing the clamping support block 403 of the left support joint to rotate inward. The rear end of the right clamping crank 4023 rotates outward under the action of the right inclined surface 4024B of the clamping push plate 4024 (that is, the rear end of the right clamping crank 4023 moves along the right inclined surface 4024B of the clamping push plate 4024), thereby causing the clamping support block 403 of the right support joint to rotate inward. When rotated to the appropriate position, the inner walls of the clamping support block 403 of the left support joint and the inner walls of the clamping support block 403 of the right support joint will clamp the tree trunk.
[0043] If the outer diameter of the tree trunk is small, during the clamping process, the rear end of the left clamping bend 4022 may move along the left inclined surface 4024A of the clamping push plate 4024 to the V-shaped groove of the left groove plate 40243, where the V-shaped groove of the left groove plate 40243 is opened by the rear end of the left clamping bend 4022. The rear end of the right clamping bend 4023 may move along the right inclined surface 4024B of the clamping push plate 4024 to the V-shaped groove of the right groove plate 40245, where the V-shaped groove of the right groove plate 40245 is opened by the rear end of the left clamping bend 4022. The groove is opened by the rear end of the right clamping bend 4023. At this time, the inner walls of the clamping support block 403 of the left support joint and the inner walls of the clamping support block 403 of the right support joint clamp the tree trunk. When the clamping engagement hydraulic cylinder 4021 drives the clamping push plate 4024 to move backward along the push channel on the clamping base plate 401, the rear end of the left clamping bend 4022 can pop out from the groove of the left groove plate 40243, and the rear end of the right clamping bend 4023 can pop out from the groove of the right groove plate 40245. The left groove plate 40243 and the right groove plate 40245 are flexible and are a kind of resilient plate that can rebound. The rebound force causes the left clamping bend 4022 and the right clamping bend 4023 to slightly reset, thereby releasing the tree trunk.
[0044] In this embodiment, the clamping push plate 4024 is disposed in the pushing channel of the clamping base plate 401. The clamping push hydraulic cylinder 4021 pushes the clamping push plate 4024 forward, thereby pushing the front ends of the left clamping crank 4022 and the right clamping crank 4023 to rotate inward under force, thereby driving the clamping support block 403 of the left support joint and the clamping support block 403 of the right support joint to rotate inward, thereby achieving the fastening effect on the tree trunk.
[0045] like Figure 3-4 As shown, the left auxiliary rod drive mechanism 407 adopts a left hydraulic cylinder. The cylinder body of the left hydraulic cylinder is fixedly connected to the left side of the inclined joint 404. One end of the push rod of the left hydraulic cylinder is fixedly connected to a left ring block 511. The inner cavity of the left ring block 511 is rotatably connected to the convex ball on the left variable angle ball 512 through a ball connection. The left variable angle ball 512 includes a convex ball and an L-shaped connecting rod. The convex ball is fixedly connected to one end of the L-shaped connecting rod, and the other end of the L-shaped connecting rod is slidably connected to the long cavity 4051 on one side of the left auxiliary rod 405. The right auxiliary rod drive mechanism 408 adopts a right hydraulic cylinder. The cylinder body of the right hydraulic cylinder is fixedly connected to the right side of the inclined joint 404. One end of the push rod of the right hydraulic cylinder is fixedly connected to a right ring block 513. The right ring block 513 and the convex ball on the right variable angle ball 514 are rotatably connected by a ball connection. The right variable angle ball 514 includes a convex ball and an L-shaped connecting rod. The convex ball is fixedly connected to one end of the L-shaped connecting rod, and the other end of the L-shaped connecting rod is slidably connected to the long cavity 4051 on one side of the right auxiliary rod 406.
[0046] The support drive mechanism 409 includes a support hydraulic cylinder. The inclined joint 404, left auxiliary rod 405, and right auxiliary rod 406 each have a cavity extending through the bottom. The support hydraulic cylinder is installed within each cavity. The push rod of the support hydraulic cylinder extends out of the cavity and connects to a lower ring block 515. A convex ball is connected to the top of the deflection support plate 410. The inner cavity of the lower ring block 515 and the convex ball of the deflection support plate 410 are rotatably connected via a ball joint. The inclined joint 404, left auxiliary rod 405, and right auxiliary rod 406 each have a pipe hole through which an infusion hose passes to connect to the support hydraulic cylinder, thereby supplying hydraulic oil to the support hydraulic cylinder.
[0047] like Figure 9 As shown, the vibrating clamp 5 includes a large clamp plate 501, a small clamp plate 502, a clamp plate hydraulic cylinder 503, and a counterweight 504. The handle of the large clamp plate 501 is provided with a pushing cavity. The handle of the small clamp plate 502 is embedded in the pushing cavity of the large clamp plate 501 and can slide within the pushing cavity. The back of the small clamp plate 502 is connected to the pushing rod of the clamp plate hydraulic cylinder 503. The clamp plate hydraulic cylinder 503 is connected to the counterweight 504, and the counterweight 504 is connected to the handle of the large clamp plate 501 through a strip connecting rod 505. An existing eccentric block vibrator is provided inside the large clamp plate 501. The eccentric block vibrator contains a motor, which drives the eccentric block to rotate to achieve vibration. The function of the counterweight 504 is to ensure that the vibrating clamp 5 is in a horizontal state when it is suspended from the top of the rotating body 2 by a flexible rope. In addition, a vertical rod is also provided on the clamping base plate 401, and the vibrating clamp 5 is suspended from the vertical rod by a flexible rope.
[0048] The main hydraulic oil tank 6 is fixedly connected to the rotating body 2. The main hydraulic oil tank 6 is connected to each hydraulic cylinder (i.e., the left hydraulic cylinder, the right hydraulic cylinder, the support hydraulic cylinder, the clamp plate hydraulic cylinder 503, etc.) through a solenoid valve group and a fluid delivery hose.
[0049] The vehicle body 1 is also equipped with a main controller and a power supply. The main controller is connected to the solenoid valve assembly and the motor in the automatic rotary disc, respectively. The power supply is connected to the main controller, solenoid valve assembly, automatic rotary disc, and eccentric block vibrator, respectively, to supply power to each component. The main controller is also equipped with a control panel. A manual input signal can be sent to the main controller via the control panel, causing the main controller to control the solenoid valve assembly to operate, thereby controlling the operation of each hydraulic cylinder. The structure of the control panel adopts existing technology, and the connection relationships between the control panel, the main controller, the solenoid valve assembly, and the various hydraulic cylinders also adopt existing technology and are not within the scope of protection of this embodiment.
[0050] The working process of this embodiment is as follows: In the initial state, the vibrating clamp 5 is placed in an empty position (suitable position) on the vehicle body 1, not suspended above the top of the vehicle body 2 and the clamping base plate 401. The vehicle body 1 adopts a commonly used tracked walking mechanism, which can be driven manually or remotely to move the vehicle body 1 to the designated position. If remote control is used, the remote control device is wirelessly connected to the main controller, and the main controller is connected to the motor in the tracked walking mechanism. The operator sends a signal to the main controller through the remote control device, and the main controller controls the motor in the tracked walking mechanism to move, thereby realizing steering and walking. After reaching the suitable position, the operator inputs a signal to the main controller through the control panel, and the main controller controls the turntable 3 to rotate, thereby adjusting the orientation of the vehicle body 2. Ultimately, the gap between the clamping support block 403 of the left support joint and the clamping support block 403 of the right support joint on the vehicle body 2 faces the tree trunk; the vehicle body 1 continues to move forward, and the tree trunk enters the gap between the clamping support block 403 of the left support joint and the clamping support block 403 of the right support joint; then, the operator inputs a signal to the main controller through the control panel, and the main controller controls the solenoid valve group to control the clamping engagement hydraulic cylinder 4021 to push the clamping push plate 4024 forward, thereby pushing the rear ends of the left clamping crank 4022 and the right clamping crank 4023 to be supported. When the force rotates outward, the front ends of the left clamping lever 4022 and the right clamping lever 4023 rotate inward, thereby causing the clamping support blocks 403 of the left and right support joints to rotate inward and clamp the tree trunk. Pressure sensors can be installed on the clamping surfaces of the left and right support joint clamping support blocks 403. These sensors feed signals back to the main controller, allowing the main controller to determine whether the clamping support blocks 403 of the left and right support joints have clamped the tree trunk. After clamping the tree trunk, if... Figure 4As shown, the push rod of the left hydraulic cylinder applies a thrust to the left annular block 511, which transmits the thrust to the left variable angle ball 512. The left variable angle ball 512 rotates within the inner cavity of the left annular block 511, and the L-shaped connecting rod of the left variable angle ball 512 slides within the long cavity 4051 on one side of the left auxiliary rod 405, thereby pushing the left auxiliary rod 405 to rotate away from the oblique joint 404. Simultaneously, the push rod of the right hydraulic cylinder applies a thrust to the right annular block 513, which transmits the thrust to the right variable angle ball 514. The right variable angle ball 514 rotates within the inner cavity of the right annular block 513, and the L-shaped connecting rod of the right variable angle ball 514 slides within the long cavity 4051 on one side of the right auxiliary rod 406, thereby pushing the right auxiliary rod 406 to rotate away from the oblique joint 404; that is, the left auxiliary rod 405 and The right auxiliary rod 406 is in an open position (i.e., in an unfolded state; after the oblique joint 404, left auxiliary rod 405, and right auxiliary rod 406 are unfolded, they are supported on the ground by the support hydraulic cylinder and the deflection support plate 410). After being unfolded to the preset position, the main controller controls the solenoid valve group to control the main hydraulic oil tank 6 to supply liquid to the support hydraulic cylinders in the oblique joint 404, left auxiliary rod 405, and right auxiliary rod 406 through the liquid delivery hose. The push rod of the support hydraulic cylinder pushes the lower ring block 515, and the lower ring block 515 pushes the convex ball of the deflection support plate 410. Under the action of the rotational connection between the inner cavity of the lower ring block 515 and the convex ball of the deflection support plate 410, the deflection support plate 410 moves towards the ground. Finally, the bottom of the deflection support plate 410 is in close contact with the ground. The bottom of the deflection support plate 410 is a disc surface. A pressure sensor can also be installed at the bottom of the deflection support plate 410. The pressure sensor feeds back a signal to the main controller in real time. The main controller can determine whether the bottom of the deflection support plate 410 is in close contact with the ground based on the signal from the pressure sensor. Once in close contact, the main controller controls the push rod of the support hydraulic cylinder to stop moving downwards. After all the bottoms of the deflection support plates 410 are in close contact with the ground, the vibrating clamp 5 is manually connected to the vehicle rotating body 2 by a flexible rope. Alternatively, the vibrating clamp 5 can be connected to the vertical bar on the base plate 401 by a flexible rope. During suspension, the tree trunk should be kept between the large clamp plate 501 and the small clamp plate 502, and the vibrating clamp 5 should be kept as horizontal as possible. Figure 9As shown, the operator inputs a signal to the main controller via the control panel. The main controller controls the solenoid valve group, which in turn controls the hydraulic cylinder 503 of the clamping plate. The hydraulic cylinder 503 pushes the small clamping plate 502 to move, thus clamping the tree trunk between the small clamping plate 502 and the large clamping plate 501. Pressure sensors can be installed on the clamping surfaces of the small clamping plate 502 and the large clamping plate 501. The pressure sensors provide real-time feedback signals to the main controller. The main controller uses the feedback signals from the pressure sensors to determine whether the small clamping plate 502 and the large clamping plate 501 have clamped the tree trunk. After clamping the tree trunk, the main controller controls the motor in the eccentric block vibrator inside the large clamping plate 501 to move, vibrating (oscillating) the tree trunk. After the operation is completed, the operator inputs a signal to the main controller via the control panel. The main controller controls the clamping plate hydraulic cylinder 503 in the oscillating clamp 5 to reset, the eccentric block vibrator stops working, the flexible rope is released, and the oscillating clamp 5 is removed from the flexible rope. Afterward, the operator inputs a signal to the main controller via the control panel, and the main controller controls each hydraulic cylinder to reset.
