Technical Field

[0001] The invention relates to the technical field of oil-tea fruit harvesting, and in particular to a spiral portable oil-tea fruit harvesting device. Background Art

[0002] At present, the oil tea fruit is generally harvested by vibration. The principle is to vibrate the oil tea tree through a vibration mechanism, and use the inertia force to make the oil tea fruit fall off the branch, so as to achieve harvesting. However, the harvesting rate of this harvesting method cannot reach 100%. The remaining oil tea fruit generally needs to be harvested manually. In order to improve the efficiency of manual harvesting, portable harvesting devices are often used.

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1As shown, this embodiment provides a spiral portable oil tea fruit harvesting device, including a hand-held 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 hand-held tube 1 and the harvesting seat 3, the harvesting tube 4 is connected to the harvesting seat 3 along the axial rotation, the harvesting seat 3 is provided with a driving mechanism for driving the harvesting tube 4 to rotate, the inner wall of the harvesting tube 4 is provided with a spiral blade 41, the harvesting tube 4, the harvesting seat 3, the extension tube 2 and the hand-held tube 1 are provided with a connected fruit channel, and the lower end of the hand-held tube 1 can be equipped with a collection bag using a throat clamp. Among them, the hand-held tube 1 and the extension tube 2 form an obtuse angle, which is more convenient to hold. At the same time, a switch 5 is provided on the front side of the hand-held tube 1 to control the start and stop of the driving mechanism, which is more convenient to operate. The switch 5 can specifically be a normally closed button switch, that is, it starts when pressed and stops when released. The use principle of this embodiment is as follows: hold the hand-held tube 1 by hand, aim the harvesting tube 4 at the oil-tea fruit, and insert the oil-tea fruit into the harvesting tube 4, then press the switch 5, the driving mechanism drives the harvesting tube 4 to rotate, and the spiral blade 41 in the harvesting tube 4 will gradually pull the oil-tea fruit to the inside during the rotation, and at the same time, the fruit pedicle of the oil-tea fruit is circumcised. Under the dual effects of pulling and cutting, the oil-tea fruit is quickly picked. At this time, the switch can be released, and the picked oil-tea fruit can automatically fall into the collection bag along the fruit channel in the harvesting tube 4, the harvesting seat 3, the extension tube 2 and the hand-held tube 1. Repeat the above actions, and the harvesting of oil-tea fruit can be completed efficiently. In order to ensure the cutting effect of the spiral blade on the fruit pedicle of the oil-tea fruit, the appropriate part of the spiral blade can be processed to be slightly sharp, and the position that is easily touched by people can be processed to be blunt. The structure of this embodiment is simple and light, easy to use, efficient in action, and can automatically complete the picking and collection of oil-tea fruit, eliminating the work of picking up oil-tea fruit from the ground, and effectively improving the overall harvesting efficiency.

[0020] Specifically, the spiral blades 41 are distributed along the entire length of the harvesting barrel 4. The spiral blades 41 are not only used to pull the tea fruit, but also to cushion the movement of the tea fruit in the harvesting barrel 4. This is because when the tea fruit is picked by being pulled by the spiral blades 41, it has a faster moving speed due to the action of inertia, and is prone to collision, causing damage to the tea fruit. The spiral blades 41 require the tea fruit to move along the spiral blades, thereby eliminating the instantaneous impact force of the tea fruit.

[0021] In order to further improve the convenience of use, the spiral blade 41 partially extends out of the harvesting tube 4. In this way, the oil-tea fruit does not need to be completely inserted into the harvesting tube 4, and the oil-tea fruit will be pulled by the spiral blade 41, which reduces the operation requirements. At the same time, it also avoids the spiral blade 41 from acting on the side of the oil-tea fruit, ensuring that it can act on the tail end of the oil-tea fruit for effective traction. Correspondingly, for safety reasons, the edge of the part of the spiral blade 41 that extends out of the harvesting tube 4 is slightly blunt, while the edge of the part in the harvesting tube 41 is slightly sharp.

[0022] In addition, the diameter of the portion of the harvesting barrel 4 outside the harvesting seat 3 is larger, so as to facilitate the cooperation with the oil-tea fruit and reduce the operation requirements; while the diameter of the portion of the harvesting barrel 4 connected to the harvesting seat 3 is smaller, on the one hand to cooperate with the setting of bearings and other components at the rotating connection with the harvesting seat 3, and on the other hand to make the position of the oil-tea fruit when it is introduced from the harvesting barrel 4 into the harvesting seat 3 relatively centered, that is, to maintain the stability of the height difference when the oil-tea fruit enters the harvesting seat 3 from the harvesting barrel 4, thereby minimizing the collision between the oil-tea fruit and the inner wall of the harvesting seat 3.

[0023] The driving mechanism includes a motor 61, a driving gear 62, and a driven gear 63. The driving gear 62 is arranged 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 cooperates with the driven gear 63. 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 driving mechanism has a simple structure, is easy to implement, and has stable and efficient action.

[0024] The harvesting seat 3 is provided with a motor accommodating portion 31, a fruit guiding portion 32 and a gear accommodating portion 33. The motor accommodating portion 31 is arranged above the fruit guiding portion 32, and the gear accommodating portion 33 is arranged on the right side of the motor accommodating portion 31 and the fruit guiding portion 32. The diameter of the gear accommodating portion 33 is larger than the diameter of the fruit guiding portion 32. By partitioning the interior of the harvesting seat 3, the various components are assembled in order to avoid mutual influence, and one end of the harvesting barrel 4 is extended into the fruit guiding portion 32 to prevent impurities in the harvesting barrel from entering the gear accommodating portion 33 and the motor accommodating portion 31, so as to ensure the stable operation of the driving mechanism. The motor accommodating portion 31 is arranged above the fruit guiding portion 32, so as to ensure that the center of gravity of the entire device is in the middle, and the operating comfort is improved.

[0025] The harvesting seat 3 includes two parts that are assembled with each other. A limit plate 331 is provided on the inner wall of the gear receiving portion 33. A mounting plate 64 is clamped between the limit plate 331 and the fruit guiding portion 32. The motor 61 is arranged on the mounting plate 64. A through hole is provided in the middle of the mounting plate 64 for the harvesting tube 4 to pass through. In this way, the motor 61 can be first assembled on the mounting plate 64, and then the mounting plate 64 is inserted between the limit plate 331 and the fruit guiding portion 32. Finally, the two parts of the harvesting seat 3 are assembled, and the stable assembly of the motor can be completed efficiently. The limit plates 331 can be multiple pieces distributed along the circumference of the gear receiving portion 33 to take into account both the limit stability and the lightweight design. Although the mounting plate 64 has a shape that matches the gear accommodating portion 33 and the motor accommodating portion 31, in order to further ensure the stability of the mounting plate position and avoid shaking along the circumferential direction, a limit block 332 is provided on the relative inner wall of the gear accommodating portion 33, and limit notches 641 that cooperate with the limit block 332 are provided on the edges of both sides of the mounting plate 64.

[0026] In addition, a limiting step 321 is provided on the inner side wall of the fruit guide part 32 along its circumference, and a bearing 7 is provided on the side of the limiting step 321 close to the harvesting tube 4. The inner and outer rings of the bearing 7 respectively match the harvesting tube 4 and the fruit guide part 32, and the driven gear 63 abuts against the side of the inner ring of the bearing 7. The bearing 7 specifically adopts a deep groove ball bearing to ensure the smooth rotation of the harvesting tube 4. In this way, the two sides of the bearing 7 are respectively limited by the limiting step 321 and the driven gear 63, and the installation position is stable. In addition, the limiting step 321 abuts against the side of the outer ring of the bearing 7, and the driven gear 63 abuts against the side of the inner ring of the bearing 7, which will not affect the rotation of the harvesting tube 4 relative to the fruit guide part 32.

[0027] Due to the setting of the bearing 7, the diameter of the harvesting cylinder 4 in the fruit guide part 32 is relatively small. Therefore, in order to enable the oil-tea fruit in the harvesting cylinder 4 to smoothly enter the fruit guide part 32, a plurality of guide ribs 322 are evenly distributed along the circumference of the inner wall of the fruit guide part 32. The widths of the two ends of the guide ribs 322 are respectively adapted to the harvesting cylinder 4 and the extension cylinder 2. The distance between adjacent guide ribs 322 is smaller than the diameter of the oil-tea fruit, thereby ensuring that the oil-tea fruit can move along the upper edge of the guide ribs 322 to avoid the oil-tea fruit being stuck between adjacent guide ribs 322, so that the oil-tea fruit can be smoothly introduced from the harvesting cylinder 4 into the extension cylinder 2 to avoid damage to the oil-tea fruit.

[0028] The two ends of the extension tube 2 are respectively plugged with the hand-held tube 1 and the harvesting seat 3, and are fastened with a hose clamp 8. The hand-held tube 1 and the harvesting seat 3 are provided with expansion joints to facilitate the fastening of the hose clamp 8. The extension tube 2 is used to extend the length of the device to harvest the oil-tea fruit at a high place. According to the specific height of the oil-tea fruit, the extension tube 2 of different lengths can be quickly replaced by the hose clamp 8. For example Figure 1 The long tube shown is more suitable for harvesting tea fruit at high altitudes, while Figure 5 The short tube shown in the figure is only used to connect the hand-held tube 1 with the harvesting seat 3, and does not extend the length of the device. It is more suitable for harvesting oil-tea fruits at low places and is also more portable. Of course, we can also design the extension tube 2 as a telescopic structure, using two or even three sections of the tube to be connected in sequence, and use a hose clamp to tighten the joints, and adjust according to needs.

[0029] The above is only a preferred specific embodiment of the present invention, which is an implementation method based on the overall concept of the present invention, and the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
