Description

Technical Field

[0001] This utility model relates to the field of camellia fruit harvesting technology, and in particular to a spiral portable camellia fruit harvesting device. Background Technology

[0002] Currently, camellia oleifera fruits are generally harvested using a vibration method. This method works by using a vibrating mechanism to cause the camellia tree to vibrate, using inertia to detach the fruits from the branches, thus achieving harvesting. However, this method cannot achieve a 100% harvest rate; the remaining fruits generally need to be harvested manually. To improve the efficiency of manual harvesting, portable harvesting devices are often used.

[0003] In the prior art, for example, invention patent ZL202211055865.9 discloses a handheld electric harvesting device for camellia oleifera fruits. This harvesting device consists of a battery pack, a handheld handle, a tilt adjustment mechanism, a frame, a motor, an angle adjustment mechanism, finger seats, impact finger groups, and a housing. The frame, motor, angle adjustment mechanism, and finger seats are located inside the housing. The tilt adjustment mechanism is connected to the handheld handle and is used to adjust the pitch angle of the frame relative to the horizontal plane. The impact finger groups are mounted on the frame via finger seats, and the motor drives the impact finger groups through a transmission system. The angle adjustment mechanism allows the impact finger groups to automatically open when subjected to external force. This device knocks the fruits off the fruiting branches using the impact finger groups, which generates significant vibration, affecting the stability of the handheld device. Furthermore, the camellia oleifera fruits on the ground need to be picked up manually, impacting harvesting efficiency.

[0004] For example, utility model patent ZL202421849240.4 discloses a handheld camellia fruit harvester, including a telescopic rod, a harvesting cylinder, and a harvesting mechanism. The harvesting cylinder is fixedly connected to the right side of the inner rod of the telescopic rod, and a through groove is opened at the bottom of the harvesting cylinder. The harvesting mechanism includes a first arched block, a second arched block, and a guide rod, etc. The first arched block is slidably connected to the outer rod of the telescopic rod, and the second arched block is fixedly connected to the top of the harvesting cylinder. Both the first and second arched blocks have through holes in their middle, and guide rods are fixedly connected to the through holes. It can extend the telescopic rod to facilitate the harvesting of camellia fruits at higher locations. The above-mentioned harvester requires precise control of the cutting action of the rod to achieve the harvesting of camellia fruits, which is difficult to operate and has low harvesting efficiency. Utility Model Content

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1As shown, this embodiment provides a spiral-type portable camellia fruit harvesting device, including a handheld tube 1, an extension tube 2, a harvesting seat 3, and a harvesting tube 4. The two ends of the extension tube 2 are respectively connected to the handheld tube 1 and the harvesting seat 3. The harvesting tube 4 and the harvesting seat 3 are rotatably connected along the axial direction. The harvesting seat 3 is provided with a drive mechanism to drive the harvesting tube 4 to rotate. The inner side wall of the harvesting tube 4 is provided with spiral blades 41. There is a fruit channel connecting the harvesting tube 4, the harvesting seat 3, the extension tube 2, and the handheld tube 1. A collection bag can be attached to the lower end of the handheld tube 1 using a hose clamp. The handheld tube 1 and the extension tube 2 form an obtuse angle, which makes it easier to hold. At the same time, a switch 5 is provided on the front side of the handheld tube 1 to control the start and stop of the drive mechanism, making operation more convenient. The switch 5 can be a normally closed push-button switch, that is, it only starts when pressed and stops when released. The operating principle of this embodiment is as follows: Hold the handheld tube 1, align the harvesting tube 4 with the camellia fruit, and place the camellia fruit into the harvesting tube 4. Then press the switch 5, and the drive mechanism will rotate the harvesting tube 4. During the rotation, the spiral blades 41 inside the harvesting tube 4 will gradually pull the camellia fruit inward, while simultaneously circumferentially cutting the stem of the fruit. Under the dual action of pulling and cutting, the camellia fruit is quickly picked. At this point, the switch can be released, and the picked camellia fruit will automatically fall into the collection bag along the fruit channel inside the harvesting tube 4, harvesting seat 3, extension tube 2, and handheld tube 1. Repeating the above actions can efficiently complete the harvesting of camellia fruit. To ensure the cutting effect of the spiral blades on the stem of the camellia fruit, the appropriate parts of the spiral blades can be processed to be slightly sharp, while the parts that are easily touched by people can be processed to be blunter. This embodiment has a simple and lightweight structure, is easy to use, and operates efficiently. It can automatically complete the picking and collection of camellia fruit, eliminating the work of picking up camellia fruit from the ground and effectively improving the overall harvesting efficiency.

[0030] Specifically, the spiral blades 41 are distributed along the entire length of the harvesting cylinder 4. The spiral blades 41 are not only used to pull the camellia fruit, but also to buffer the movement of the camellia fruit in the harvesting cylinder 4. When the camellia fruit is picked by the spiral blades 41, it has a relatively fast movement speed under the action of inertia, which makes it easy to bump and damage the camellia fruit. The spiral blades 41 make the camellia fruit move along the spiral blades, thereby eliminating the instantaneous impact force of the camellia fruit.

[0031] To further improve ease of use, the spiral blades 41 extend partially out of the harvesting cylinder 4. This eliminates the need to completely insert the camellia fruit into the harvesting cylinder 4; the fruit will be pulled by the spiral blades 41, thus reducing operational requirements. Simultaneously, it prevents the spiral blades 41 from acting on the sides of the camellia fruit, ensuring that they act on the tail end for effective traction. Correspondingly, for safety reasons, the edge of the portion of the spiral blades 41 extending out of the harvesting cylinder 4 is slightly blunt, while the edge of the portion inside the harvesting cylinder 41 is slightly sharp.

[0032] In addition, the portion of the harvesting cylinder 4 outside the harvesting seat 3 has a larger diameter to facilitate the handling of the camellia fruit and reduce operational requirements; while the portion of the harvesting cylinder 4 connected to the harvesting seat 3 has a smaller diameter. This is to accommodate the bearings and other components at the rotatable connection point with the harvesting seat 3, and to ensure that the camellia fruit is relatively centered when it is introduced into the harvesting seat 3 from the harvesting cylinder 4. This maintains the stability of the height difference of the camellia fruit when it enters the harvesting seat 3 from the harvesting cylinder 4, thereby minimizing the impact between the camellia fruit and the inner wall of the harvesting seat 3.

[0033] The drive mechanism includes a motor 61, a driving gear 62, and a driven gear 63. The driving gear 62 is located at the output end of the motor 61, and the driven gear 63 is sleeved and fixed on the outer surface of the harvesting cylinder 4. The driving gear 62 and the driven gear 63 cooperate with each other. That is, the motor 61 drives the harvesting cylinder 4 to rotate through the driving gear 62 and the driven gear 63 to realize the harvesting action. The drive mechanism has a simple structure, is easy to implement, and operates stably and efficiently.

[0034] The harvesting station 3 is equipped with a motor housing 31, a fruit guide 32, and a gear housing 33. The motor housing 31 is located above the fruit guide 32, and the gear housing 33 is located to the right of the motor housing 31 and the fruit guide 32. The diameter of the gear housing 33 is larger than the diameter of the fruit guide 32. By dividing the internal space of the harvesting station 3 into sections, the components are assembled in an orderly manner, avoiding mutual interference. This also allows one end of the harvesting cylinder 4 to extend into the fruit guide 32, preventing impurities from the harvesting cylinder from entering the gear housing 33 and the motor housing 31, thus ensuring the stable operation of the drive mechanism. Placing the motor housing 31 above the fruit guide 32 ensures that the center of gravity of the entire device is in the middle, improving operational comfort.

[0035] The harvesting base 3 comprises two interlocking parts. A limiting plate 331 is provided on the inner wall of the gear housing 33. An mounting plate 64 is engaged between the limiting plate 331 and the fruit guide 32. The motor 61 is mounted on the mounting plate 64, which has a through hole in the center for the harvesting cylinder 4 to pass through. Thus, the motor 61 can be first assembled onto the mounting plate 64, then the mounting plate 64 can be inserted between the limiting plate 331 and the fruit guide 32, and finally the two parts of the harvesting base 3 can be joined together, efficiently completing the stable assembly of the motor. The limiting plate 331 can be multiple pieces distributed circumferentially along the gear housing 33 to balance limiting stability and lightweight design. Although the mounting plate 64 has a shape that adapts to the gear housing 33 and the motor housing 31, in order to further ensure the stability of the mounting plate position and avoid the occurrence of vibration in the circumferential direction, a limiting block 332 is provided on the relative inner side wall of the gear housing 33, and a limiting notch 641 that matches the limiting block 332 is provided on both sides of the mounting plate 64.

[0036] In addition, a limiting step 321 is provided along the circumference of the inner wall of the fruit guide 32. A bearing 7 is provided on the side of the limiting step 321 near the harvesting cylinder 4. The inner and outer rings of the bearing 7 are respectively matched with the harvesting cylinder 4 and the fruit guide 32, and the driven gear 63 abuts against the side of the inner ring of the bearing 7. The bearing 7 is specifically a deep groove ball bearing to ensure the smooth rotation of the harvesting cylinder 4. In this way, the two sides of the bearing 7 are limited by the limiting step 321 and the driven gear 63 respectively, and the installation position is stable. Furthermore, the limiting step 321 abuts against the side of the outer ring of the bearing 7, while the driven gear 63 abuts against the side of the inner ring of the bearing 7, so as not to affect the rotation of the harvesting cylinder 4 relative to the fruit guide 32.

[0037] Due to the bearing 7, the diameter of the harvesting cylinder 4 inside the fruit guide section 32 is relatively small. Therefore, in order to allow the camellia fruit in the harvesting cylinder 4 to smoothly enter the fruit guide section 32, several guide ribs 322 are evenly distributed along the circumference of the inner side wall of the fruit guide section 32. The width of the two ends of the guide ribs 322 are adapted to the harvesting cylinder 4 and the extension cylinder 2, respectively. The distance between adjacent guide ribs 322 is less than the diameter of the camellia fruit, thereby ensuring that the camellia fruit can move along the upper edge of the guide ribs 322 and preventing the camellia fruit from getting stuck between adjacent guide ribs 322. This allows the camellia fruit to be smoothly guided from the harvesting cylinder 4 into the extension cylinder 2, avoiding damage to the camellia fruit.

[0038] The two ends of the extension tube 2 are respectively inserted into the hand-held tube 1 and the harvesting seat 3, and are both secured with hose clamps 8. Both the hand-held tube 1 and the harvesting seat 3 have expansion joints to facilitate the tightening of the hose clamps 8. The extension tube 2 is used to extend the length of this device for harvesting camellia oleifera fruits at higher locations. Depending on the specific height of the camellia oleifera fruits, extension tubes 2 of different lengths can be quickly replaced using the hose clamps 8. For example... Figure 1 The long tube shown is more suitable for harvesting camellia fruits from higher locations, while... Figure 5 The short tube shown has an extension tube that is only used to connect the handheld tube 1 and the harvesting seat 3, without extending the length of the device. This makes it more suitable for harvesting camellia fruits at lower locations and also more convenient. Of course, we can also design the extension tube 2 as a telescopic structure, using two or even three tubes to be nested together in sequence, and using hose clamps to secure them at the joints. Adjustments can be made as needed.

[0039] The above are merely preferred embodiments of this utility model, and are implementations based on the overall concept of this utility model. Furthermore, the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
