Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, specifically a cam-vibration type camellia fruit harvesting device. Background Technology

[0002] Camellia oleifera is a unique woody oil crop in my country, with its fruit containing over 90% unsaturated fatty acids, giving it extremely high economic and nutritional value. However, currently, camellia oleifera fruit is mostly harvested manually, which is labor-intensive, inefficient, and increasingly difficult to meet the urgent needs of the camellia oleifera industry's development due to the aging rural population. Furthermore, most of my country's camellia oleifera forests are currently planted in hilly and mountainous areas, and the planting is not standardized, making large-scale harvesting machinery unsuitable for the geographical conditions. Therefore, developing an efficient and portable camellia oleifera fruit harvesting device is a pressing issue that needs to be addressed.

[0003] CN219165177U discloses a slapping-type camellia fruit harvesting device, which mainly consists of a frame, mounting frame, slapping mechanism, motor, adjustment mechanism, housing, limiting linkage, and adjusting linkage. The adjustment mechanism can adjust the relative positions of multiple slapping rods to make them fit the tree body in an approximately arc-shaped structure. The motor drives the slapping rods to slap the camellia tree body to achieve harvesting. This device has the advantages of being flexible, lightweight, and saving labor costs, but it also has the following shortcomings: 1. In terms of harvesting effect, some fruits are difficult to fall off due to the slapping force and angle, and are easily scattered far away, making them inconvenient to collect; 2. In terms of impact on trees, it is easy to break fragile branches, which is not conducive to tree growth and yield maintenance; 3. In terms of portability, the operation of moving the frame and other components is limited in complex terrain, resulting in insufficient flexibility. Utility Model Content

[0027] The present invention can be further described through the following embodiments; however, the scope of the present invention is not limited to the following embodiments. It should be understood that the embodiments described herein are disclosed by way of illustration only, and the present invention is not intended to limit its scope to the details of the construction and arrangement of the components described below or illustrated in the figures. Furthermore, in describing preferred embodiments, specific terminology will be used for clarity. It should be understood that each specific term includes all technical equivalents that operate in a similar manner to achieve a similar purpose.

[0028] Example: Figures 1 to 7 As shown, it includes a handcart 2, a hook 9 for hooking branches, a connecting rod 8 connected to the hook 9, a cam reciprocating vibration mechanism 7 for driving the connecting rod 8 to reciprocate, a hand handle 5, and a power unit 1 provided on the handcart 2 to provide power to the cam reciprocating vibration mechanism 7. Preferably, the power unit 1 is a gasoline engine.

[0029] Specifically, the cam reciprocating vibration mechanism 7, as shown in the figure... Figures 5 to 7As shown, the device includes a movable rod 10, a linear bearing 11, a frame 12, a fixed bracket 14, a cylindrical cam 15, a bearing 16, and a grooved wheel 18. The frame 12 has an open front and rear structure. The upper part of the frame 12 is provided with a linear bearing 11. The lower end of the movable rod 10 passes through the linear bearing 11 and is connected to the upper end of the fixed bracket 14. The camshaft 151 of the cylindrical cam 15 is installed in the lower inner part of the frame 12 through the bearing 16. The camshaft 151 is connected to the output end of the power device 1 through a flexible shaft 3. One end of the flexible shaft 3 passes through the hand handle 5. The outer wall of the cylindrical cam 15 is provided with a wheel groove 152. The two sides of the cylindrical cam 15 are symmetrically provided with grooved wheels 18 that cooperate with the wheel groove 152. The wheel axle of the grooved wheel 18 is installed at the lower end of the fixed bracket 14 by bolts.

[0030] like Figure 5 As shown, in this embodiment, a guide structure is provided between the frame 12 and the fixed bracket 14. Specifically, the frame 12 is provided with elongated oval holes 121 on both sides, and the fixed bracket 14 is provided with guide wheels 13 that cooperate with the elongated oval holes 121 on both sides. The guide wheels 13 and the elongated oval holes 121 cooperate to guide and improve the stability of the frame 12's movement, which helps to reduce shaking and deviation during the movement.

[0031] like Figure 6 As shown, the lower end of the fixed bracket 14 is provided with adjustment holes 141 on both sides for bolts to pass through. The installation position of the fixed bracket 14 can be adjusted by setting the adjustment holes 141.

[0032] like Figure 5 As shown, the bottom of the frame 12 is provided with a guide sleeve 17 for the flexible shaft 3 to pass through. The guide sleeve 17 can protect and orient the flexible shaft 3.

[0033] In this embodiment, the hook claw is covered with a rubber protective sleeve, which can reduce damage to the camellia oleifera fruit tree and protect the hook claw from wear.

[0034] In this embodiment, the hook 9 is made of two plates welded together at a 60-degree angle. This design helps to better hook onto branches and improve harvesting efficiency.

[0035] In this embodiment, the hand lever 4 is equipped with a throttle handle 6, which is connected to the gasoline engine via a throttle cable 4. The speed of the gasoline engine can be adjusted by using the throttle handle 6.

[0036] In this embodiment, the movable rod 10 and the connecting rod 8 have an adjustable length structure; the movable rod 10 is provided with an external thread, and the connecting rod 8 is provided with an internal thread that mates with the external thread. The adjustable length structure can adapt to different tree branch lengths and positions, and flexibly adjust the position of the hook 9.

[0037] During operation, the harvesting device of this utility model is moved to the vicinity of the camellia tree, the gasoline engine is turned on, and the hook 9 is moved close to the branch of the camellia tree by holding the lever 5 so that the hook 9 hooks the branch. The throttle handle 6 is adjusted so that the gasoline engine runs at a suitable speed. When the gasoline engine is working, the power is transmitted to the camshaft 151 through the flexible shaft 3. The rotation of the camshaft 151 drives the grooved wheels 18 on both sides to move regularly along the groove 152. When the grooved wheels 18 move, they drive the movable rod 10 and the fixed bracket 14 to reciprocate. The reciprocating motion of the movable rod 10 causes the hook 9 to vibrate the branch, so that the camellia fruit falls off due to inertia at the junction with the fruit stem. After the camellia fruit falls off, the throttle handle 6 is released, the hook 9 is removed, and the above actions are repeated to achieve continuous harvesting.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
