Description

Technical fields:

[0001] This utility model relates to the field of harvesting tools, specifically a single-disc pendulum olive harvester with a simple structure, few parts, and low manufacturing cost. Background technology:

[0002] During the olive harvest season, olives are picked by climbing the trees manually or using ladders and homemade tools. Climbing the trees poses safety hazards and can damage the branches, while also being inefficient. Using ladders also presents safety risks and is relatively inefficient.

[0003] To improve the harvesting efficiency of tree fruits such as olives, a harvesting tool with a powered striking structure, namely the olive harvester, was invented based on the height problem encountered during harvesting and the size characteristics of the harvested products. It is used to strike the branches of the fruit tree, causing the branches to shake, so that the fruit will detach and fall.

[0004] For example, Chinese utility model patent application number 202322726277.X discloses a double-swing rod mechanism with a built-in enclosed structure and its olive-making machine. It includes a mechanism shell, a motor body, two gear assemblies, and two swing rods. The mechanism shell includes a fixed seat and two gear covers that cover the upper and lower ends of the fixed seat. The fixed seat includes a motor fixing part at the rear and a gear fixing part formed at the front end of the motor fixing part. The upper and lower ends of the gear fixing part are respectively connected to the two gear covers. The front side of the gear cover has a swing window for the swing rods to extend out. Through the structural design of the mechanism shell and gear assemblies, the gear body with an eccentric shaft that drives the two swing rods to swing can be enclosedly installed inside the mechanism shell. The swing rods are exposed to the outside of the mechanism shell through the swing window, thereby maximizing the overall sealing degree and achieving the maximum dustproof design for the gear assembly.

[0005] However, the aforementioned olive machine uses two gear assemblies to drive two swing rods to swing, which in turn drive two beaters to swing and beat the fruit. Its structure is complex, with many parts, and the installation is cumbersome and the manufacturing cost is high. In addition, the two gear assemblies are stacked on top of each other, making them tall and heavy, which makes the overall size of the mechanism shell large and inconvenient to store and carry, causing great trouble for users.

[0006] In view of the above, the inventors propose the following technical solution. Utility model content:

[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] See Figure 1-9 As shown, a single-plate pendulum olive machine includes a control handle 1, a support tube 2, a housing 3, and two first beaters 4 and second beaters 5 rotatably mounted on both sides of the upper end of the housing 3, and a drive device 6 installed inside the housing 3 to drive the first beaters 4 and second beaters 5 to swing relative to the housing 3.

[0030] The support tube 2 is a telescopic positioning tube, which can extend when in use and retract when not in use, making it extremely convenient to use.

[0031] The drive device 6 includes a housing 61 installed inside the outer casing 3, a gear 63 rotatably installed inside the housing 61 via a first shaft 62, a drive gear 64 meshing with the gear 63, a motor 65 for mounting with and driving the drive gear 64 to rotate, and a connecting rod 66 connected to an eccentric portion 631 on the gear 63 and driven by the gear 63 to generate reciprocating motion. The end of the connecting rod 66 extends outside the housing 61 and the outer casing 3, and is simultaneously connected to the first striker 4 and the second striker 5 to synchronously drive the first striker 4 and the second striker 5 to swing relative to the outer casing 3. When the drive device 6 is working, the drive gear 64 is driven to rotate by the motor 65. While the drive gear 64 is rotating, it drives a gear disk 63 to rotate. This causes the eccentric part 631 of the gear disk 63 to pull a connecting rod 66 to move back and forth. At this time, since the first striker 4 and the second striker 5 are rotatably mounted on both sides of the upper end of the outer casing 3, the connecting rod 66 will pull the first striker 4 and the second striker 5 to swing relative to the outer casing 3 when it moves back and forth. During the swinging process, the first striker 4 and the second striker 5 can strike the olives on the olive tree to knock them down and make it possible to harvest the olives. Since the drive device 6 uses a gear disc 63 and a connecting rod 66 to pull the first striker 4 and the second striker 5 to drive the first striker 4 and the second striker 5 to swing synchronously relative to the outer shell 3, it has fewer parts, a simple structure, is relatively easy to install, and has a lower manufacturing cost. At the same time, it can make the thickness of the entire drive device 6 lower, making the overall size of the drive device 6 larger, which is convenient for storage and carrying, and the weight is relatively small, making it extremely convenient to use.

[0032] To make the drive device 6 operate more stably, the following design was also made: the drive gear 64 is rotatably mounted in the housing 61 through several first bearings 641, which makes the rotation of the drive gear 64 more stable. The shaft of the motor 65 is fixed to the drive gear 64. A ring of first helical teeth 632 is provided around the upper end surface of the gear disk 63. The first helical teeth 632 mesh with the second helical teeth 642 provided on the outside of the drive gear 64. Its assembly structure is stable and can reduce the height of the entire drive device 6.

[0033] The assembly structure of the first shaft 62 is as follows: the upper end of the first shaft 62 is rotatably mounted in the housing 61 through several second bearings 621, and the lower end of the first shaft 62 is rotatably mounted in the housing 61 through several third bearings 622. That is, both the upper and lower ends of the first shaft 62 are assembled with the housing 61 through bearings, so that the first shaft 62 rotates more smoothly and more stably.

[0034] The gear disk 63 is provided with a central shaft hole 633 that passes through the upper and lower ends and through the lower end face of the eccentric part 631. The inner wall of the central shaft hole 633 is provided with a first keyway 634. The outer surface of the first shaft body 62 is provided with a second keyway 623, which corresponds to the first keyway 634. The key block 67 is embedded and fixed in the second keyway 623 and the first keyway 634 on both sides, so that the gear disk 63 and the first shaft body 62 are more stably assembled and have better synchronization.

[0035] To improve the dynamic balance of the gear disk 63 during rotation, the following design was also made: the gear disk 63 is provided with several through holes 630 that penetrate the upper and lower end faces and are used to reduce material and achieve dynamic balance.

[0036] The middle part of the first striking device 4 is rotatably connected to one side of the upper end of the outer casing 3 by a first bolt 40, and the middle part of the second striking device 5 is rotatably connected to the other side of the upper end of the outer casing 3 by a second bolt 50. The parts of the first striking device 4 and the second striking device 5 that are close to each other are connected to the connecting rod 66, so that the first striking device 4 and the second striking device 5 can swing synchronously relative to the outer casing 3 through a connecting rod 66.

[0037] The assembly structure of the connecting rod 66 is as follows:

[0038] One end of the connecting rod 66 is integrally formed with a collar 661, in which a first bushing 662 is embedded. The first bushing 662 is fitted around the eccentric portion 631. A retaining spring 663 is engaged with the eccentric portion 631, and the retaining spring 663 contacts the first bushing 662 to confine the first bushing 662 to the periphery of the eccentric portion 631. This allows the connecting rod 66 to be stably mounted around the eccentric portion 631 and to rotate relative to the periphery of the eccentric portion 631. The first bushing 662 can be replaced with a bearing.

[0039] The other end of the connecting rod 66 is fitted with a second bushing 664, and a second shaft 665 passes through the second bushing 664. A first protrusion 401 and a second protrusion 501 are respectively provided on the side of the first striker 4 and the second striker 5 that are close to each other. The first protrusion 401 and the second protrusion 501 are distributed vertically, and a first shaft groove provided on the lower end face of the first protrusion 401 is fitted onto the upper end of the second shaft 665. A second shaft groove 502 provided on the upper end face of the second protrusion 501 is fitted onto the lower end of the second shaft 665, so that the second shaft 665 forms a stable connection with both the first protrusion 401 and the second protrusion 501, so that the first striker 4 and the second striker 5 can swing synchronously relative to the outer casing 3 via a connecting rod 66. The second bushing 664 can be replaced with a bearing.

[0040] The housing 61 includes a lower housing 611 and an upper housing 612.

[0041] The lower housing 611 has a stepped groove 601 at its upper end, and a first notch 602 on one side of the lower housing 611. A connecting cylinder 603 is provided on the other side of the lower housing 611. The drive gear 64 is fixed in the connecting cylinder 603 by several first bearings 641. The upper housing 612 has a flange 604 at its lower end, and a first limiting piece 605 on one side of the upper housing 612. The upper housing 612 is installed by the flange 604 and the stepped groove 601, and is locked by several screws. The first limiting piece 605 is embedded in the first notch 602 and forms a window. The connecting rod 66 passes through the window and can move back and forth in the window.

[0042] The control handle 1 houses a control circuit board and has a slot 11 for mounting a rechargeable battery 7. The slot 11 contains a power terminal electrically connected to the control circuit board. The control handle 1 also has a power socket 12 electrically connected to the control circuit board. In other words, this invention can draw power in two ways: first, by directly mounting the rechargeable battery 7 into the slot 11 on the control handle 1 and electrically connecting it to the power terminal, thus powering the entire olive machine; second, by inserting a plug with a cord into the power socket 12, with the other end of the plug connected to a power source such as a car battery, which can also power the entire olive machine. This satisfies different usage requirements and is extremely convenient to use.

[0043] The power socket 12 has a threaded section 121 at its upper end. When the plug with cord is inserted into the power socket 12, the nut on the plug with cord is screwed into the threaded section 121 to form a stable connection between the plug with cord and the power socket 12, which effectively prevents the two from accidentally separating.

[0044] The lower end of the control handle 1 is provided with a limiting part 13. The limiting part 13 is provided with a clamping groove 131 for clamping the positioning power cord along its side. The power cord with the plug can be clamped in the clamping groove 131, making it more convenient to use.

[0045] The first striking device 4 includes a first body 41 and a plurality of first striking rods 42 inserted and fixed to the upper end of the first body 41 and distributed outwards at an offset angle, and a first angle positioning sleeve 43 sleeved on all the first striking rods 42 and positioning the angle of each first striking rod 42. The middle part of the first body 41 is rotatably connected to one side of the upper end of the outer shell 3, and the side of the first body 41 is rotatably connected to the end of the connecting rod 66. The first angle positioning sleeve 43 has a plurality of interconnected cylinders 431 that are distributed outwards at an offset angle. One cylinder 431 is sleeved on the outside of one first striking rod 42, which can position all the first striking rods 42 and keep the extension direction of the first striking rods 42 positioned. This makes the assembly structure of the first striking rods 42 and the first body 41 more stable and can better strike the olive fruit.

[0046] The structure of the second striking device 5 is the same as that of the first striking device 4, and will not be described in detail here.

[0047] In summary, when the drive device 6 is working, the drive gear 64 is driven to rotate by the motor 65. While the drive gear 64 is rotating, it drives a gear disk 63 to rotate. This causes the eccentric part 631 of the gear disk 63 to pull a connecting rod 66 to move back and forth. At this time, since the first striker 4 and the second striker 5 are rotatably mounted on both sides of the upper end of the outer casing 3, the connecting rod 66 will pull the first striker 4 and the second striker 5 to swing relative to the outer casing 3 when it moves back and forth. During the swinging process, the first striker 4 and the second striker 5 can strike the olives on the olive tree to knock them down and thus achieve olive harvesting. Since the drive device 6 uses a gear disc 63 and a connecting rod 66 to pull the first striker 4 and the second striker 5 to drive the first striker 4 and the second striker 5 to swing synchronously relative to the outer shell 3, it has fewer parts, a simple structure, is relatively easy to install, and has a lower manufacturing cost. At the same time, it can make the thickness of the entire drive device 6 lower, making the overall size of the drive device 6 larger, which is convenient for storage and carrying, and the weight is relatively small, making it extremely convenient to use.

[0048] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
