[0014] 1. The utility model proposes a fruit picking bin support frame, which supports a fruit picking device by hingedly connecting a first support frame and a second support frame to each other, and hingedly connecting the first support frame and the second support frame at both ends of a hydraulic cylinder. The extension or contraction of the hydraulic cylinder drives the first support frame to move relative to the second support frame to change the ground clearance of the fruit picking device, so that the hydraulic cylinder can support the fruit picking device at a suitable height.

The fruit picking machine has better versatility. At the same time, when it is found that the fruit picking efficiency is not good, the fruit picking efficiency can be improved by fine-tuning the hydraulic cylinder, thereby further improving the adaptability and flexibility of the fruit picking machine.

[0015] 2. The first support frame includes a mounting frame, a mounting rod and a pulling rod, and the fruit picking device is installed on the mounting frame. One end of the hydraulic cylinder is hinged to the mounting rod, one end of the mounting rod is hinged to the second support frame at a first hinge point, and the other end of the mounting rod is hinged to the mounting frame at a second hinge point; one end of the pulling rod is hinged to the second support frame at a third hinge point, and the other end of the pulling rod is hinged to the mounting frame at a fourth hinge point. With this arrangement, the four hinge points constitute a quadrilateral structure, and the extension or contraction of the hydraulic cylinder drives the mounting rod to move relative to the second support frame, thereby lifting the fruit picking device as a whole. The fruit picking device has a better lifting effect, and avoids the excessive height difference between the front and rear ends of the fruit picking device caused by the fruit picking device rotating around a certain axis. The extension or contraction stroke of the hydraulic cylinder can be reduced.

[0016] 3. The first hinge point and the second hinge point of the mounting rod and the third hinge point and the fourth hinge point of the pull rod form the four endpoints of a parallelogram.

[0018] 5. The mounting frame includes a cross frame and a vertical pole fixedly connected to the cross frame, the second hinge point is located on the cross frame, and the fourth hinge point is located on the vertical pole, wherein the mounting pole mainly plays a supporting role, and is subjected to greater force than the pull rod. The mounting pole is hinged to the cross frame or one end of the vertical pole close to the cross frame to bear the gravity of the main fruit picking device, the vertical pole and the pull rod are hinged, and the pull rod plays an auxiliary supporting role. Such an arrangement simplifies the design structure of the mounting frame, avoids performance overflow caused by excessive structural strength at the hinge position of the mounting frame and the pull rod, and thus reduces the cost of the mounting frame.

[0019] 6. The utility model also discloses a fruit picking machine, including a traveling mechanism and a frame, wherein the traveling mechanism is installed on the frame, and the movement of the traveling mechanism drives the fruit picking machine to move forward.

When the ground is tilted, the adjusting nut of the screw rod on the connecting part can be adjusted to adjust the left and right tilt angles of the fruit picking device to adapt to the tilt of the ground, and then the locking nut can be tightened to reduce or avoid loosening of the adjusting nut during operation of the fruit picking device. The fruit picking machine has better adaptability to ground conditions and better stability when working.

[0021] 8. An anti-loosening member is provided between the adjusting nut and the first support frame, and / or between the locking nut and the first support frame. This arrangement further reduces or avoids the occurrence of loosening of the adjusting nut of the fruit picking device during operation.

The joint bearing can effectively absorb impact and the whole building, and it can automatically align its center, so as to absorb assembly errors and reduce the difficulty of assembly between the fruit picking device and the first support frame. The connection part adopts a joint bearing to be hinged to the fruit picking device, so that the bumps and vibrations caused by the uneven ground when the fruit picking machine is working can be absorbed by the joint bearing, reducing the shaking of the fruit picking device during movement, thereby increasing the service life of the fruit picking device; and reducing the difficulty of assembly of the fruit picking machine, thereby effectively reducing the manufacturing cost of the fruit picking machine.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Embodiment 1:

[0041] like Figures 1 to 5 As shown, a fruit picking machine proposed in an embodiment of the utility model includes a frame, a traveling mechanism and a fruit picking device 500. The fruit picking device 500 and the traveling mechanism are installed on the frame. The traveling mechanism drives the fruit picking machine to move forward. The fruit picking device 500 is used to collect fruits on the ground while the fruit picking machine is moving.

[0042] The fruit picking machine further comprises a fruit picking bin support frame, a fruit picking device 500 is mounted on the fruit picking bin support frame, and the fruit picking bin support frame is mounted on the frame of the fruit picking machine. The fruit picking bin support frame comprises a hydraulic cylinder 400 and a first support frame 100 and a second support frame 200 hinged to each other, the fruit picking device 500 is mounted on the first support frame 100, the second support frame 200 is fixed to the frame, and both ends of the hydraulic cylinder 400 are hinged to the first support frame 100 and the second support frame 200 respectively.

[0043] In this embodiment, the first support frame 100 is arranged approximately horizontally, and the second support frame 200 is arranged approximately vertically. The hydraulic cylinder 400 is a single-rod single-acting oil cylinder, one end of which is provided with a retractable piston rod 401, and the piston rod 401 extends out of a part of the hydraulic cylinder 400 and is hinged to the first support frame 100. There is pressurized oil injection liquid in the hydraulic chamber of the hydraulic cylinder 400, so that both ends of the hydraulic cylinder 400 have a supporting force to support the fruit picking device 500. Figure 4 As shown, the hydraulic cylinder 400 supports the fruit picking device 500 in the working position, and at this time, the distance between the bottom of the fruit picking device 500 and the ground is small. Figure 3As shown, by injecting pressurized oil into the oil filling port of the hydraulic cylinder 400, the piston rod 401 is stretched by the force, and the piston rod 401 pushes the first support frame 100 to move relative to the second support frame 200. The fruit picking device 500 is lifted by the hydraulic cylinder 400, and the fruit picking device 500 is in a transfer position, and the fruit picking machine can move to the next working area.

[0044] Among them, a liquid pump can be used to fill the hydraulic cylinder 400 with oil, and the liquid pump and the hydraulic cylinder 400 are connected by a pipeline. The liquid pump can be a manual pump or an electric pump. An operable one-way valve is provided between the liquid pump and the hydraulic cylinder 400, and the one-way valve is operated to make it open or closed. The one-way valve is closed to limit the oil in the hydraulic cylinder 400 from returning to the liquid tank of the liquid pump, and the hydraulic cylinder 400 can support the fruit picking device 500 at any position. The one-way valve is opened, and under the action of the gravity of the fruit picking device 500 and the first support frame 100, the oil in the hydraulic cylinder 400 is pressed back into the liquid tank of the liquid pump, and the height of the fruit picking device 500 is reduced accordingly.

[0045] It is understandable that the hydraulic cylinder 400 may also be a double-acting cylinder, and the oil pump injects oil into different oil filling ports of the hydraulic cylinder 400 to respectively achieve compression or extension of the hydraulic cylinder 400.

[0046] It is understandable that the hydraulic cylinder 400 usually uses oil as a medium for transmitting pressure, but the hydraulic cylinder 400 can also use other liquids, such as water-based liquid, emulsion, synthetic liquid, etc.

[0047] In this embodiment, the hydraulic cylinder 400 is installed below the first support frame 100, so that the hydraulic cylinder 400 extends to push the fruit picking device 500 to rise, and the hydraulic cylinder 400 compresses to drive the fruit picking device 500 to lower.

[0048] In some other embodiments, the hydraulic cylinder 400 may also be installed above the first support frame 100, so that the compression of the hydraulic cylinder 400 drives the fruit picking device 500 to rise, and the extension of the hydraulic cylinder 400 drives the fruit picking device 500 to lower.

[0049] In some other embodiments, the first support frame 100 may be arranged substantially vertically, and the second support frame 200 may be arranged substantially horizontally.

[0050] The fruit picking bin support frame of the present embodiment, the first support frame 100 and the second support frame 200 are hinged to each other, and the two ends of the hydraulic cylinder 400 are respectively hinged to the first support frame 100 and the second support frame 200 to support the fruit picking device 500. The extension or contraction of the hydraulic cylinder 400 drives the first support frame 100 to move relative to the second support frame 200 to change the ground clearance of the fruit picking device 500, so that the hydraulic cylinder 400 can support the fruit picking device 500 at a suitable height, and the fruit picking machine can switch the ground clearance of the fruit picking device 500 under different working conditions of fruit picking operation and transfer, thereby avoiding the fruit picking machine from damaging the fruit picking device 500 during transfer or requiring the use of other vehicles for transfer; at the same time, the ground clearance of the fruit picking device 500 can be adjusted by adjusting the hydraulic cylinder 400 in the working position, and the fruit picking machine can pick up different kinds of fruits, and the fruit picking machine has better versatility. At the same time, when it is found that the fruit picking efficiency is not good, the fruit picking efficiency can be improved by fine-tuning the hydraulic cylinder, thereby further improving the adaptability and flexibility of the fruit picking machine.

[0051] Embodiment 2:

[0052] Based on Example 1, Figure 1 , Figure 2 As shown, in this embodiment, the first support frame 100 includes a mounting frame 110, a mounting rod 120 and a pulling rod 130, the fruit picking device 500 is installed on the mounting frame 110, one end of the hydraulic cylinder 400 is hinged to the mounting rod 120, one end of the mounting rod 120 is hinged to the second support frame 200 at a first hinge point 121, the other end of the mounting rod 120 is hinged to the mounting frame 110 at a second hinge point 122, one end of the pulling rod 130 is hinged to the second support frame 200 at a third hinge point 131, and the other end of the pulling rod 130 is hinged to the mounting frame 110 at a fourth hinge point 132.

[0053] With such arrangement, the four hinge points form a quadrilateral structure, and the extension or retraction of the hydraulic cylinder 400 drives the mounting rod 120 to move relative to the second support frame 200, thereby changing the height of the fruit picking device 500. The fruit picking device 500 has a better lifting effect, and the problem of excessive height difference between the front and rear ends when the fruit picking device 500 rotates around a certain axis is avoided. When avoiding obstacles of the same height, the extension or retraction stroke of the hydraulic cylinder 400 can be reduced. At the same time, by reducing the height difference between the front and rear ends of the fruit picking device 500 during the lifting process, the back and forth shaking of the fruit picking device 500 during the lifting process is reduced.

[0054] Preferably, in this embodiment, the first hinge point 121 and the second hinge point 122 of the mounting rod 120 and the third hinge point 131 and the fourth hinge point 132 of the pull rod 130 form four endpoints of a parallelogram.

[0055] With such arrangement, the four hinge points form a parallelogram structure, and the front and rear ends of the fruit picking device 500 are lifted by the same distance. When avoiding obstacles of the same height, the extension or retraction stroke of the hydraulic cylinder 400 can be further reduced. At the same time, since the front and rear ends of the fruit picking device 500 are lifted by the same distance, the forward and backward shaking of the fruit picking device 500 during the lifting process is further reduced, and the fruit picking device 500 is more stable during the lifting process.

[0056] More preferably, in this embodiment, the mounting frame 110 includes a horizontal frame 111 and a vertical pole 112 fixedly connected to the horizontal frame 111 , the fruit picking device 500 is mounted on the horizontal frame 111 , the second hinge point 122 is located on the horizontal frame 111 , and the fourth hinge point 132 is located on the vertical pole 112 .

[0057] Of the mounting rod 120 and the pull rod 130, the mounting rod 120 is used to bear most of the load, and the pull rod 130 serves as an auxiliary support. Therefore, the strength of the component hinged to the pull rod 130 should not be too high. Too high strength will lead to performance overflow, which will increase the cost. By arranging the vertical rod 112 on the horizontal frame 111, the structure of the mounting frame 110 can be simplified, and the structural strength of the hinge position between the mounting frame 110 and the pull rod 130 is avoided to be too high to cause performance overflow, thereby reducing the cost of the mounting frame 110.

[0058] In some other embodiments, the second hinge point 122 is located at one end of the vertical pole 112 close to the horizontal frame 111, and the fourth hinge point 132 is located at one end of the vertical pole 112 away from the horizontal frame 111. The structural strength of the end of the vertical pole 112 close to the horizontal frame 111 is much greater than that of the end away from the horizontal frame 111, so such a setting can also avoid overflow of strength performance.

[0059] In another preferred embodiment, there are two mounting rods 120 disposed on the left and right sides of the mounting frame 110, there are two pull rods 130 disposed on the left and right sides of the mounting frame 110, and there are two hydraulic cylinders 400 disposed on the left and right sides of the fruit picking bin support frame, respectively.

[0060] With such arrangement, both the left and right sides of the fruit picking device 500 are supported, and the fruit picking device 500 is more stable. At the same time, two hydraulic cylinders 400 are arranged, and the two hydraulic cylinders 400 are respectively connected to the two sides of the fruit picking device 500, so that the working state of the hydraulic cylinder 400 is more stable, avoiding uneven force on the hydraulic cylinder 400 and causing damage to the hydraulic cylinder 400.

[0061] Embodiment three:

[0062] Based on the first and second embodiments, Figure 2 , Figure 5As shown, in this embodiment, the left side of the fruit picking device 500 is rotatably connected to the first support frame 100 via a pin shaft, and the right side is connected to the first support frame 100 via a connecting portion 300. The connecting portion 300 includes a screw rod 310, on which an adjusting nut 311 and a locking nut 312 are threaded. The locking nut 312 is arranged above the adjusting nut 311, and the locking nut 312 and the adjusting nut 311 press the first support frame 100 between the two.

[0063] With such arrangement, the fruit picking device 500 can fine-tune the left or right tilt angle. When the ground is tilted, the adjusting nut 311 of the screw rod 310 on the connecting part 300 can be adjusted to adjust the left and right tilt angles of the fruit picking device 500 to adapt to the tilt of the ground. The locking nut 312 can then be tightened to reduce or avoid loosening of the adjusting nut 311 during operation of the fruit picking device 500. The fruit picking machine is more adaptable to ground conditions and has better stability when working.

[0064] In some other embodiments, the right side of the fruit picking device 500 may be rotatably connected to the first support frame 100 via a pin, and the left side may be connected to the first support frame 100 via a connecting portion 300 .

[0065] In this embodiment, preferably, an anti-loosening member is provided between the adjusting nut 311 and the first supporting frame 100. Such a configuration further reduces or avoids the occurrence of loosening of the adjusting nut 311 during operation of the fruit picking device 500.

[0066] It is understandable that the anti-loosening member may also be disposed between the locking nut 312 and the first support frame 100 .

[0067] In another preferred embodiment, there are multiple connecting parts 300, and the multiple connecting parts 300 are arranged front and back on the left side or right side of the fruit picking device 500. Such an arrangement improves the support of the supporting part for the fruit picking device 500, thereby improving the stability of the fruit picking device 500 and reducing the shaking of the fruit picking device 500 when working.

[0068] In another preferred embodiment, the connecting portion 300 includes a joint bearing 320 , the fruit picking device 500 is hinged to the joint bearing 320 , and the screw rod 310 is connected below the joint bearing 320 .

[0069] The joint bearing 320 can effectively absorb impact and the whole building, and it can automatically align its center, thereby absorbing assembly errors and reducing the difficulty of assembling the fruit picking device 500 and the first support frame 100. The connecting part 300 adopts the joint bearing 320 to be hinged with the fruit picking device 500, so that the bumps and vibrations caused by the uneven ground when the fruit picking machine is working can be absorbed by the joint bearing 320, reducing the shaking of the fruit picking device 500 during movement, thereby increasing the service life of the fruit picking device 500; and reducing the assembly difficulty of the fruit picking machine, thereby effectively reducing the manufacturing cost of the fruit picking machine.

[0070] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
