Description

Technical Field

[0001] This utility model belongs to the field of agricultural product primary processing machinery technology, specifically relating to an amplitude-adjustable vibration harvesting machine. Background Technology

[0002] Camellia oleifera is mostly planted on mountains, not occupying basic farmland. A single planting provides long-term benefits, effectively creating employment opportunities and increasing farmers' income. Traditional camellia oleifera fruit harvesting relies on manual labor. In the steep mountainous environment, this method is not only labor-intensive and inefficient, but also difficult to hire and expensive, severely hindering the development of the camellia oleifera industry. Especially on high, steep slopes, where machines generally cannot access the terrain, harvesting becomes even more challenging. Therefore, inventing a telescopic, vibrating, portable camellia oleifera fruit harvester suitable for simultaneously harvesting camellia oleifera flowers and fruits on steep mountain slopes is of significant practical importance.

[0003] my country has several hundred varieties of camellia oleifera, including the Changlin, Cenruan, and Xianglin series. They mainly grow in the high mountains and hills of the south. The fruit stalk tension is about 10-45 N. This requires the harvesting machine to not only have different extension and vibration frequencies, but also adjustable amplitude. Varieties with high fruit stalk tension require large amplitude, while varieties with low fruit stalk tension require small amplitude. However, the harvesting mechanism in the current technology often cannot adjust the tension amplitude. Moreover, the handheld harvesting mechanism in the current technology is too violent and can easily cause injury to branches and the operator's arms, failing to provide shock absorption and cushioning.

[0004] Therefore, in view of the problems existing in the prior art, there is an urgent need to provide a vibrating tapping machine with adjustable tapping amplitude and good shock absorption and buffering effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an amplitude-adjustable vibratory harvester that features a reasonable structure, comfortable operation, high harvesting efficiency, and effective protection of fruit trees. The eccentricity is adjusted by changing the position of the slider on the large gear disc, achieving precise amplitude adjustment in three levels: 60 mm, 80 mm, and 100 mm. A permanent magnet brushless motor paired with a frequency converter allows for independent adjustment of the machine's vibration frequency, independent of amplitude control. A unique spring-slide handle shock absorption mechanism effectively isolates and absorbs high-frequency vibrations transmitted from the machine casing. A U-shaped silicone pad embedded inside the harvesting head provides a soft buffer interface, and its symmetrical holes accommodate branches of varying thicknesses while effectively preventing direct damage to the bark from the metal hooks.

The drive motor rotates to drive the transmission worm gear to rotate, the transmission worm gear rotates to drive the large gear plate to rotate, and the rotation of the large gear plate drives the transmission connecting rod to reciprocate to transmit power to the mining head.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1

[0021] like Figure 1 As shown, an amplitude-adjustable vibrating tapping machine includes a tapping head 1, a tapping rod 2, a transmission mechanism 3, an amplitude adjustment mechanism 4, a handle shock absorber 5, and a tapping machine housing 6. The front end of the tapping machine is set as the tapping head 1, and the rear end of the tapping head 1 is connected to the tapping rod 2. The tail end of the tapping rod 2 is connected to the transmission mechanism 3, and the transmission mechanism 3 is connected to the amplitude adjustment mechanism 4. The handle shock absorber 5 is connected to the side of the amplitude adjustment mechanism 4. The transmission mechanism 3, the amplitude adjustment mechanism 4, and the handle shock absorber 5 are all installed on the tapping machine housing 6.

[0022] like Figure 2 As shown, an amplitude-adjustable vibrating harvester has a harvesting head 1 configured as a hook structure. A U-shaped silicone pad 11 is embedded in the inner contact surface of the harvesting head 1. Several symmetrically distributed harvesting head damping holes 12 are opened on both sides of the U-shaped silicone pad 11 on the harvesting head 1. The thickness of the U-shaped silicone pad 11 is slightly greater than the depth of the U-shaped groove, so that its outer surface can protrude from the inner side of the hook, ensuring that the silicone pad makes flexible contact first when in contact with the tree branch. The several symmetrically distributed harvesting head damping holes 12 on the U-shaped silicone pad 11 increase the deformation capability of the U-shaped silicone pad 11, enabling it to better adapt to and cover branches of different diameters.

[0023] like Figure 3As shown, an amplitude-adjustable vibratory tapping machine has a tapping rod 2 configured as a coaxially nested telescopic power rod, including a telescopic rod sleeve 21 and a telescopic power rod 23 nested sequentially. Adjacent telescopic rod sleeves 21 and telescopic power rods 23 are connected by a built-in elastic positioning pin on the telescopic power rod 23 and a positioning hole 22 on the wall tube of the telescopic rod sleeve 21. The telescopic rod sleeve 21 has at least two sections, with one end of the section closest to the transmission mechanism 3 connected to the transmission mechanism 3 and the other end connected to the telescopic power rod. The lever 23 is connected by a built-in elastic positioning pin and a positioning hole 22; one end of the telescopic sleeve 21 closest to the tapping head 1 is installed and connected to the tapping head 1, and the other end is connected to the telescopic power lever 23 by a built-in elastic positioning pin and a positioning hole 22; the tapping rod 2 adopts a multi-section coaxial sleeve structure made of high-strength aluminum alloy. The sections or segments are connected by built-in elastic positioning pins and positioning holes on the pipe wall, which can realize stepless adjustment and locking of the length to adapt to the tapping operation of camellia trees of different heights.

[0024] like Figure 4 , 5 As shown, an amplitude-adjustable vibrating tapping machine has a transmission mechanism 3 including a transmission connecting rod 31, a transmission slider 32, and an amplitude adjustment hole 33. The amplitude adjustment hole 33 is opened on a large gear disk 41. The transmission slider 32 is installed in the amplitude adjustment hole 33 and transmits power to the transmission connecting rod 31 and the large gear disk 41. The drive motor 43 rotates, which drives the transmission worm gear 42 to rotate. The rotation of the transmission worm gear 42 drives the large gear disk 41 to rotate. The rotation of the large gear disk 41 drives the transmission connecting rod 31, which transmits power to the tapping head 1, to reciprocate.

[0025] like Figure 5 As shown, an amplitude-adjustable vibratory tapping machine has an amplitude adjustment mechanism 4 including a large gear 41, a transmission worm gear 42, and a drive motor 43. The large gear 41 is mounted on the transmission mechanism 3, and the large gear 41 and the transmission worm gear 42 are connected by gear meshing. The drive motor 43 is connected to the rear end of the transmission worm gear 42.

[0026] like Figure 5 As shown, an amplitude-adjustable vibrating tapping machine is provided, with helical meshing teeth installed on both the large gear disc 41 and the transmission worm gear 42. The transmission ratio between the large gear disc 41 and the transmission worm gear 42 is 4:1. The drive motor 43 is a permanent magnet brushless motor, which is electrically connected to a lithium battery through a frequency converter. The frequency converter and the lithium battery are installed on the tapping machine housing 6. The drive motor 43 is connected to the frequency converter and the lithium battery power supply. By operating the frequency converter, the speed of the drive motor 43 can be smoothly adjusted, thereby independently changing the vibration frequency of the tapping machine and achieving independent and precise control of amplitude and frequency.

[0027] like Figure 4 , 5As shown, an amplitude-adjustable vibratory harvester has several symmetrically distributed amplitude adjustment holes 33 with eccentricities of 30 mm, 40 mm, and 50 mm on the radially distributed end face of the large gear disc 41. When the transmission slider 32 connects the transmission connecting rod 31 to the amplitude adjustment holes 33 with different eccentricities, vibration amplitudes of 60 mm, 80 mm, and 100 mm are achieved, adapting to harvesting pull forces of 10-20 N, 20-35 N, and 35-45 N respectively. When the transmission slider 32 is fixed to the amplitude adjustment hole 33 with an eccentricity of 30 mm, an amplitude of 60 mm is achieved, suitable for varieties with a fruit stalk pull force of 10-20 N; when the transmission slider 32 is fixed to the amplitude adjustment hole 33 with an eccentricity of 40 mm, an amplitude of 80 mm is achieved, suitable for varieties with a pull force of 20-35 N; and when the transmission slider 32 is fixed to the amplitude adjustment hole 33 with an eccentricity of 50 mm, an amplitude of 100 mm is achieved, suitable for varieties with a pull force of 35-45 N. N varieties.

[0028] like Figure 6 As shown, an amplitude-adjustable vibrating tapping machine has a handle shock absorber 5 including a sliding rod 51, a shock-absorbing spring 52, a shock-absorbing block 53, and an operating handle 54. The shock-absorbing block 53 is fixedly installed on the tapping machine housing 6. Two parallel sliding rods 51 are installed on the shock-absorbing block 53. The shock-absorbing spring 52 and the operating handle 54 are installed on the sliding rods 51.

[0029] like Figure 5 , 6 As shown, an amplitude-adjustable vibrating tapping machine has shock-absorbing blocks 53 distributed at both ends and the middle of a sliding rod 51. Shock-absorbing springs 52 are fitted onto the sliding rod 51 between the shock-absorbing blocks 53. The operating handle 54 extends through the tapping machine housing 6 at both ends and is distributed between the shock-absorbing blocks 53 at the ends and the middle of the sliding rod 51. Shock-absorbing springs 52 are fitted onto the sliding rod 51 between the operating handle 54 and the shock-absorbing blocks 53. One end of the shock-absorbing spring 52 abuts against the shock-absorbing block 53, and the other end abuts against the operating handle 54. A motor switch button electrically connected to the drive motor 43 is installed on the operating handle 54. When the machine housing vibrates, the shock-absorbing blocks 53 move with the vibration, while the operating handle 54 remains relatively stationary due to inertia, causing the shock-absorbing spring 52 to compress and rebound, effectively absorbing and dissipating vibration energy and significantly reducing the vibration transmitted to the operator's hand.

[0030] Furthermore, the mining machine housing 6 includes a left housing and a right housing that are interlocked. A sealing groove is installed at the joint surface of the left housing and the right housing, and a sealing and shock-absorbing strip is installed in the sealing groove to provide good dust and moisture protection for the internal mechanism.

[0031] The working principle is as follows: The operator first fixes the transmission slider 32 in the corresponding amplitude adjustment hole 33 on the large gear plate 41 according to the characteristics of the target camellia fruit variety, and sets an appropriate harvesting amplitude. When the transmission slider 32 is fixed in the amplitude adjustment hole 33 with an eccentricity of 30 mm, an amplitude of 60 mm is achieved, which is suitable for varieties with a fruit stalk tension of 10-20 N; when the transmission slider 32 is fixed in the amplitude adjustment hole 33 with an eccentricity of 40 mm, an amplitude of 80 mm is achieved, which is suitable for varieties with a tension of 20-35 N; when the transmission slider 32 is fixed in the amplitude adjustment hole 33 with an eccentricity of 50 mm, an amplitude of 100 mm is achieved, which is suitable for varieties with a tension of 35-45 N. Then, adjust the striking rod 2 to a suitable length and lock it according to the actual situation: press down the built-in elastic positioning pin on the telescopic power rod 23 and stretch it, so that the telescopic power rod 23 nested in the telescopic rod sleeve 21 is pulled out completely, and fixed by inserting the built-in elastic positioning pin into the positioning hole 22 on the wall tube of the telescopic rod sleeve 21 to prevent slippage. Adjust the number of sections or segments of the telescopic rod sleeve 21 and the telescopic power rod 23 according to the actual length. The drive motor 43 is started by operating the motor switch button on the handle 54. The drive motor 43 rotates, which drives the transmission worm gear 42 to rotate. The transmission worm gear 42 rotates, which drives the large gear plate 41 to rotate. The rotation of the large gear plate 41 drives the transmission connecting rod 31 connected to the large gear plate 41 to reciprocate crank motion, thereby realizing the reciprocating linear motion of the mining rod 2. The power is transmitted to the mining head 1 through the mining rod 2, causing it to vibrate with a set amplitude and frequency. After the harvesting head 1 hooks onto the branch through the U-shaped silicone pad 11, it transmits the vibration to the fruit branch. The fruit falls off using the principle of inertia. During this process, the U-shaped silicone pad 11 protects the bark from damage. The shock-absorbing block 53 of the handle shock absorber 5 moves with the vibration, while the operating handle 54 remains relatively stationary due to inertia. This causes the shock-absorbing spring 52 to compress and rebound on the sliding rod 51, effectively absorbing and dissipating vibration energy and effectively reducing the vibration transmitted to the hand, thus achieving efficient, comfortable, and damage-free mechanized harvesting.

[0032] In this invention, the harvester adjusts the eccentricity by changing the position of the slider on the large gear disc, achieving precise amplitude adjustment of 60 mm, 80 mm, and 100 mm. This allows for accurate matching of harvesting needs with varying fruit stalk tension, ensuring harvesting efficiency while effectively preventing damage to the fruit trees. The use of a permanent magnet brushless motor with a frequency converter allows for independent adjustment of the machine's vibration frequency, enabling the equipment to adapt to more diverse harvesting scenarios and enhancing its practicality. A unique spring-slide handle shock absorption mechanism effectively isolates and absorbs high-frequency vibrations transmitted from the machine casing, significantly reducing vibrations transmitted to the operator's hands and greatly improving operational comfort and the feasibility of long-term operation. The U-shaped silicone pad embedded inside the harvesting head provides a soft cushioning interface, and its symmetrical holes accommodate branches of varying thicknesses while effectively preventing direct damage to the bark from the metal hooks, thus providing excellent protection for the fruit trees.
