[0001] The utility model relates to the technical field of agricultural machinery, in particular to a fruit picking machine. Background Art

[0002] When the fruit picking machine picks fruits, the distance of the fruit picking mechanism from the ground has a great influence on the fruit picking efficiency. If the distance from the ground is too large, the fruit leakage rate will be greatly increased. If the distance from the ground is too small, it will be difficult for the fruit to enter under the fruit picking mechanism, resulting in a significant reduction in the fruit picking efficiency.

[0003] The fruit picking machine in the prior art usually adopts a hydraulic cylinder or an electric cylinder to drive an upgrading mechanism to adjust the distance of the fruit picking mechanism from the ground, but such a solution has a complex structure and a high price, which leads to an increase in the cost of the fruit picking machine. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and propose a fruit picking machine to solve the problems of complex structure and high price of components for adjusting the distance between the fruit picking mechanism and the ground in the prior art fruit picking machines.

[0005] In order to achieve the above technical objectives, the utility model proposes a fruit picking machine, including a frame and a walking mechanism and a fruit picking mechanism installed on the frame, the walking mechanism drives the fruit picking machine to move, and the fruit picking mechanism picks fruits when the fruit picking machine moves, and also includes a lifting assembly, the walking mechanism includes a front wheel assembly, the front wheel assembly includes a front wheel vertical shaft, the frame can be slidably mounted on the front wheel vertical shaft, the lifting assembly includes a rotating rod and an internal threaded portion, one end of the rotating rod can be rotatably limited on the front wheel vertical shaft, the rotating rod includes an external threaded portion, the internal threaded portion is screwed with the external threaded portion, the frame limits the rotation of the internal threaded portion, the rotation of the external threaded portion drives the internal threaded portion to move up and down, and the movement of the internal threaded portion changes the distance from the ground of the front end of the frame.

[0006] Preferably, the internal threaded portion is formed at the upper end of the frame.

[0007] Preferably, the internal threaded portion is a nut, and the upper end of the frame is provided with a limiting groove with an open lower end, and the internal threaded portion is limited in the limiting groove.

[0008] Preferably, the lifting assembly further comprises a locking nut threadedly engaged with the external threaded portion, wherein the locking nut is disposed above the internal threaded portion and is crimped onto the vehicle frame.

[0009] Preferably, a locking handle is provided on the locking nut.

[0010] Preferably, an anti-loosening member is provided between the locking nut and the frame.

[0011] Preferably, an operating part is installed on the upper end of the rotating rod.

[0012] Preferably, the operating part is an adjustment dial or an adjustment handle.

[0013] Preferably, a bearing is provided between the front wheel vertical shaft and the rotating rod.

[0014] Preferably, a limiting portion is provided at the upper end of the front wheel vertical shaft, and the limiting portion limits the frame from being separated from the upper end of the front wheel vertical shaft.

[0015] After adopting the above technical solution, the utility model has the following beneficial effects.

[0016] 1. The utility model proposes a fruit picking machine, which realizes the rotation of the rotating rod and the internal threaded part of the frame to drive the internal threaded part to move up and down, thereby changing the ground clearance of the fruit picking mechanism. Compared with the technical solution of the existing technical group using hydraulic cylinders or electric cylinders, the hydraulic cylinders or electric cylinders require a liquid pump or battery, supporting pipes or circuits, and supporting lifting mechanisms, and the structure is relatively complex, resulting in an increase in the cost of the fruit picking machine; while the utility model cooperates with the front wheel vertical shaft, the rotating rod and the frame, and uses the screw thread to make the rotation of the rotating rod adjust the ground clearance of the fruit picking mechanism. The structure of the present disclosure is relatively simple, and the screw thread method is reliable and durable, so that the cost of the fruit picking machine can be effectively reduced.

[0017] 2. The internal threaded portion is formed at the upper end of the frame. With this arrangement, the connection between the internal threaded portion and the frame is more secure, the clearance between the internal threaded portion and the frame is avoided, and the accuracy of rotation adjustment is improved.

[0018] 3. The internal threaded portion is a nut, and a limiting groove with an open lower end is provided at the upper end of the frame. The internal threaded portion is limited in the limiting groove. With this arrangement, since the internal threaded portion and the frame are separately arranged, the frame is not directly connected to the rotating rod, and therefore the frame can be more conveniently disassembled from the rotating rod, and the maintenance and replacement of the frame or the front wheel assembly are more convenient.

[0019] 4. The lifting assembly also includes a locking nut threaded with the external threaded portion. The locking nut is arranged above the internal threaded portion and is crimped onto the frame. By tightening the locking nut, the locking force between the locking nut, the frame and the rotating rod is increased, and the rotating rod is not easy to rotate, so that when the fruit picking machine is bumpy or shaken during the movement, it is not easy to change the ground clearance of the fruit picking mechanism, thereby effectively maintaining the fruit picking efficiency of the fruit picking machine when the fruit picking machine is working.

[0020] 5. A locking handle is provided on the locking nut. This arrangement makes it easier for the operator to lock the locking nut, thereby improving the operator's operating experience.

[0021] 6. An anti-loosening part is provided between the locking nut and the frame. By providing an anti-loosening part between the locking nut and the frame, the anti-loosening effect of the locking nut is better improved, and the fruit picking efficiency of the fruit picking machine is further maintained when the fruit picking machine is working.

[0022] 7. An operating part is installed at the upper end of the rotating rod. This arrangement is more conducive to the operator to operate when adjusting the distance between the fruit picking mechanism and the ground. The operator does not need to use tools to operate, which improves the operator's use experience.

[0023] 8. The operating part is an adjustment dial or an adjustment handle. Such an arrangement increases the lever distance between the operating part and the rotating rod, so that the operator can operate the operating part more effortlessly to rotate the rotating rod, thereby improving the operator's user experience.

[0024] 9. A bearing is provided between the front wheel vertical shaft and the rotating rod. By providing the bearing between the front wheel vertical shaft and the rotating rod, the rotating rod can rotate more smoothly relative to the front wheel vertical shaft, and the user has a better feel when adjusting the lifting assembly.

[0025] 10. A limit portion is provided at the upper end of the front wheel vertical shaft, which limits the frame from being separated from the upper end of the front wheel vertical shaft. The limit portion can limit the movement range of the frame to prevent the frame from being separated from the front wheel vertical shaft due to excessive adjustment of the lifting assembly.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment 1:

[0040] like Figures 1 to 3As shown, a fruit picking machine proposed in an embodiment of the utility model includes a frame 200, a traveling mechanism 100 and a fruit picking mechanism 400. The traveling mechanism 100 and the fruit picking mechanism 400 are installed on the frame 200. The operation of the traveling mechanism 100 drives the fruit picking machine to move forward. The fruit picking mechanism 400 picks fruits during the movement of the fruit picking machine. The fruit picking mechanism 400 is close to the front end of the frame 200. The fruit picking machine also includes a lifting assembly 300, and the lifting assembly 300 includes a rotating rod 310 and an internal threaded portion 320. The traveling mechanism 100 includes a front wheel assembly 110 and a rear wheel assembly 120. The front end of the frame 200 is installed on the front wheel assembly 110, and the rear end of the frame 200 is installed on the rear wheel assembly 120. The front wheel assembly 110 includes a front wheel vertical shaft 111, and the frame 200 can be slidably sleeved on the front wheel vertical shaft 111. The lower end of the rotating rod 310 is limited to rotate at the upper end of the front wheel vertical shaft 111. The rotating rod 310 includes an external threaded portion 311, which is screwed with the internal threaded portion 320. The frame 200 limits the rotation of the internal threaded portion 320, so that the rotation of the external threaded portion 311 drives the internal threaded portion 320 to move up and down. The up and down movement of the internal threaded portion 320 drives the front end of the frame 200 to move up and down, and the rear end of the frame 200 is relatively stationary. The up and down movement of the front end of the frame 200 changes the angle between the frame 200 and the ground, thereby changing the ground clearance of the fruit picking mechanism 400 installed on the frame 200.

[0041] The technical solution using hydraulic cylinders or electric cylinders requires a liquid pump or battery, supporting pipes or circuits, and a supporting lifting mechanism, and the structure is relatively complex, which leads to an increase in the cost of the fruit picking machine. However, the utility model cooperates with the front wheel vertical shaft 111, the rotating rod 310 and the frame 200, and utilizes the screw thread engagement so that the rotation of the rotating rod 310 can adjust the ground clearance of the fruit picking mechanism 400. The structure of the present invention is relatively simple, and the screw thread engagement method is reliable and durable, so that the cost of the fruit picking machine can be effectively reduced.

[0042] In this embodiment, the internal threaded portion 320 is a nut, and a limiting groove 201 with an open lower end is provided at the upper end of the frame 200. The internal threaded portion 320 is limited in the limiting groove 201, and the groove wall of the limiting groove 201 limits the rotation of the internal threaded portion 320. Specifically, a connecting portion 210 is provided at the upper end of the frame 200, and the connecting portion 210 is located above the front wheel vertical shaft 111. The connecting portion 210 is provided with a limiting groove 201 with an open lower end, and the internal threaded portion 320 is installed in the limiting groove 201. The groove wall of the limiting groove 201 limits the rotation of the internal threaded portion 320.

[0043] In this configuration, since the internal threaded portion 320 is separately configured from the frame 200 and the frame 200 is not directly connected to the rotating rod 310, the frame 200 can be more conveniently disassembled from the rotating rod 310, and the maintenance and replacement of the frame 200 or the front wheel assembly 110 are more convenient.

[0044] In some other embodiments, the internal thread portion 320 may be formed at the upper end of the frame 200. For example, the upper end of the frame 200 is provided with a connecting portion 210, the connecting portion 210 is located above the front wheel vertical shaft 111, and the connecting portion 210 is provided with an internal thread to form the internal thread portion 320, or the connecting portion 210 is welded with the internal thread portion 320.

[0045] With such arrangement, the connection between the internal thread portion 320 and the frame 200 is more secure, the clearance between the internal thread portion 320 and the frame 200 is avoided, and the accuracy of rotation adjustment is improved.

[0046] In this embodiment, a bearing is preferably provided between the front wheel vertical shaft 111 and the rotating rod 310. By providing a bearing between the front wheel vertical shaft 111 and the rotating rod 310, the rotating rod 310 can rotate more smoothly relative to the front wheel vertical shaft 111, and the user feels better when adjusting the lifting assembly 300.

[0047] In another preferred embodiment, a limiting portion 112 is provided at the upper end of the front wheel shaft 111, and the limiting portion 112 limits the frame 200 from being separated from the upper end of the front wheel shaft 111. In this embodiment, the limiting portion 112 is a retaining spring, which is installed at the upper end of the front wheel shaft 111. The retaining spring and the sliding hole of the frame 200 are in interference fit, thereby limiting the separation of the frame 200. In some other embodiments, the limiting portion 112 may also be a boss portion provided at the upper end of the front wheel shaft 111, and the boss portion is fixedly connected to the front wheel shaft 111.

[0048] The limiting portion 112 can limit the movement range of the frame 200 to prevent the frame 200 from being separated from the front wheel vertical shaft 111 due to excessive adjustment of the lifting assembly 300.

[0049] The lower end of the rotating rod 310 can be limited on the bearing by a retaining spring, and the bearing is limited to the upper end of the front wheel vertical shaft 111 by the retaining spring, so that the lower end of the rotating rod 310 is rotationally limited to the upper end of the front wheel vertical shaft 111.

[0050] Embodiment 2:

[0051] Based on the first embodiment, Figure 1 to Figure 2 As shown, in the present embodiment, the lifting assembly 300 also includes a locking nut 330, and the locking nut 330 has an internal thread. The locking nut 330 is threadedly engaged with the external thread portion 311, and the locking nut 330 is arranged above the internal thread portion 320 and is crimped to the frame 200, and the locking nut 330 is tightened to increase the locking force between the locking nut 330, the frame 200 and the rotating rod 310. The rotating rod 310 is not easy to rotate, so that when the fruit picking machine is bumpy or shaken during the running process, it is not easy to change the ground clearance of the fruit picking mechanism 400, thereby effectively maintaining the fruit picking efficiency of the fruit picking machine when the fruit picking machine is working.

[0052] In this embodiment, preferably, a locking mobile phone 331 is provided on the locking nut 330. Such a configuration makes it easier for the operator to lock the locking nut 330, thereby improving the operating experience of the operator.

[0053] In another preferred embodiment, an anti-loosening member is provided between the locking nut 330 and the frame 200. Exemplarily, the anti-loosening member is a spring washer provided between the locking nut 330 and the frame 200.

[0054] By providing an anti-loosening member between the locking nut 330 and the frame 200, the anti-loosening effect of the locking nut 330 is better improved, and the fruit picking efficiency of the fruit picking machine is further maintained when the fruit picking machine is working.

[0055] For other contents not described in this embodiment, please refer to Embodiment 1.

[0056] Embodiment three:

[0057] Based on embodiments 1 to 2, Figure 1 to Figure 2 As shown, in this embodiment, an operating portion 312 is installed at the upper end of the rotating rod 310 .

[0058] Such a configuration is more conducive to the operator to operate when adjusting the distance between the fruit picking mechanism 400 and the ground. The operator does not need to use tools to operate, thereby improving the operator's use experience.

[0059] In this embodiment, the operating part 312 is preferably an operating dial or an operating handle. This arrangement increases the lever distance between the operating part 312 and the rotating rod 310, and the operator can operate the operating part 312 more labor-savingly to rotate the rotating rod 310, thereby improving the user experience of the operator.

[0060] For other contents not described in this embodiment, reference may be made to the above embodiments.

[0061] 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.
