[0030] Specifically, when in use, the fixing frame 10 is fixed to the rear side of the agricultural tractor through three fixing parts 11, and the connecting shaft 21 is connected to the rear output shaft of the agricultural tractor, and one end of the rope is fixed to the rope fixing position 31, and the other end is fixed to the fruit tree. After the rear output shaft of the agricultural tractor is started, the connecting shaft 21 is driven to rotate, and the connecting shaft 21 drives the outer ring of the eccentric bearing seat 22 to vibrate, and the outer ring of the eccentric bearing seat 22 drives the transmission rod 23 to reciprocate in the up and down directions, and the transmission shaft drives the shaking arm 30 to reciprocate at high speed and form vibration, and the vibration is transmitted to the fruit tree through the rope connecting the rope fixing position 31 and the fruit tree, so that the fruit on the fruit tree is shaken off. After harvesting a fruit tree, the user can remove the rope fixed on the fruit tree, drive the agricultural tractor to move to another fruit tree that has not been harvested, and fix the rope to the fruit tree that has not been harvested, and harvest again.

[0031] The technical solution of the utility model is as follows: three fixing parts 11 distributed in a triangle are arranged on the fixing frame 10, and a first installation position 12 is formed in the fixing frame 10, and a second installation position 13 is arranged on the side of the fixing frame 10 facing away from the fixing part 11; the connecting shaft 21 is rotatably installed at the first installation position 12, the rocking arm 30 is rotatably installed at the second installation position 13, the inner ring of the eccentric bearing seat 22 is installed on the end of the connecting shaft 21 facing away from the fixing part 11, and a transmission rod 23 is arranged on the outer ring of the eccentric bearing seat 22; the transmission rod 23 is hinged to the rocking arm 30, and a rope fixing position 31 is arranged at one end of the rocking arm 30 away from the transmission rod 23, one end of the rope can be fixed at the rope fixing position 31, and the other end can be fixed to the fruit tree.

[0032] In this way, the fixing frame 10 can be installed on the rear end of the agricultural tractor through the three fixing parts 11, and the connecting shaft 21 can be connected to the rear output shaft of the agricultural tractor. In this way, when the rear output shaft of the agricultural tractor is started, the rear output shaft drives the connecting shaft 21 to rotate, and the connecting shaft 21 rotates on the inner ring of the eccentric bearing seat 22, driving the eccentric bearing seat 22 to vibrate, and the eccentric bearing seat 22 drives the transmission rod 23 to reciprocate in the up and down directions, and the transmission rod 23 drives the shaking arm 30 to reciprocate at high speed, so that the shaking arm 30 vibrates, and the vibration is transmitted to the fruit tree through the rope, so that the fruit on the fruit tree is shaken down.

[0033] In this way, a first mounting position 12 is provided inside the fixing frame 10, and a fixing portion 11 and a second mounting position 13 are respectively provided on both sides of the fixing frame 10, so that the vibration harvester can be installed at the rear end of the agricultural tractor. At the same time, the shaft is installed in the first mounting position 12 and extends to both ends of the fixing frame 10, and the shaking arm 30 is installed in the second mounting position 13. In this way, the structure of the vibration harvester can be simplified, making the vibration harvester lighter and the production cost lower.

[0034] In some embodiments, the fixing frame 10 includes three connecting rods 14, which are connected end to end and fixed one by one, and a first installation position 12 is formed between the three connecting rods 14. The fixing portion 11 is correspondingly arranged at each two connected connecting rods 14. Specifically, the three connecting rods 14 are spliced ​​into a fixing frame 10 in a triangular shape, and the connecting shaft 21 is installed in the space between the three connecting rods 14. In this way, the fixing frame 10 has a simple structure and good stability.

[0035] In some embodiments, two spaced mounting plates 15 are provided at the upper end of the fixing frame 10, the extension direction of the two mounting plates 15 is parallel to the extension direction of the connecting shaft 21, the pin 16 passes through the two mounting plates 15 to form a second mounting position 13, and the shaking arm 30 is rotatably mounted on the pin 16. Specifically, the shaking arm 30 is directly rotatably mounted on the pin 16 between the two mounting plates 15, and the structure of the shaking arm 30 is simpler than that of the fixing frame 10 to rotatably mount the shaking arm 30 by providing a bearing. Furthermore, the fixing frame is fixed to the mounting plate by welding, so that the fixing frame and the mounting plate are fixed more firmly.

[0036] In some embodiments, the ends of the two mounting plates 15 facing away from the second mounting position 13 form a fixing portion 11. Specifically, in this way, while the second mounting position 13 is formed by the two mounting plates 15, a fixing portion 11 is also formed. As long as two additional fixing portions 11 are provided on the mounting frame, three fixing portions 11 can be formed. Compared with providing three separate fixing portions 11, this structure is simpler.

[0037] In some embodiments, a protective plate 40 is provided above the fixing frame 10, and the protective plate 40 is spaced from the shaking arm 30 in the direction in which the eccentric bearing seat 22 points to the fixing frame 10. Specifically, when the rope falls off from the fruit tree during operation, one end that falls off from the fruit tree will rebound toward the other end, and the provision of the protective plate 40 can prevent the rope from rebounding to the agricultural tractor or a person, thereby preventing the agricultural tractor from being damaged or the user from being injured.

[0038] In some embodiments, the protective plate 40 is detachably mounted on the fixing frame 10 by means of threaded fasteners. Specifically, the protective plate 40 can be fixed more securely by means of threaded fasteners, and in this way, when the protective plate 40 is damaged, it can be removed by means of threaded fasteners and replaced with a new protective plate 40, or after the fixing frame 10 is removed, it is convenient to store or transport the vibration harvester. In addition, in other embodiments, the protective plate 40 is fixed to the fixing frame by welding.

[0039] In some embodiments, the shaking arm 30 is provided with a plurality of spaced rope fixing positions 31. Specifically, the shaking arm 30 can be fixed to the rope fixing positions 31 at different positions so as to adjust the angle of the rope vibrating the fruit tree.

[0040] In some embodiments, the mounting position is provided with a bearing seat 17, and the connecting shaft 21 is mounted on the inner ring of the bearing seat 17. Specifically, the connecting shaft 21 is mounted on the bearing seat 17, the rotation is relatively stable, and the service life is also longer.

[0041] In some embodiments, a plurality of reinforcing ribs 18 are connected between the bearing seat 17 and the fixing frame 10. Specifically, when the transmission mechanism 20 vibrates, the vibration is transmitted to the fixing frame 10 and the bearing seat 17, so that the reinforcing ribs 18 are arranged to fix the bearing seat 17 more securely.

[0042] In some embodiments, a section of the rocking arm 30 provided with a rope fixing position 31 is inclined in the direction of the second mounting position 13 toward the fixing frame 10. Specifically, when the rope is fixed at a higher position on the trunk of the fruit tree, the vibration force is greater than when the rope is fixed at a lower position on the trunk of the fruit tree, so the position of the end of the rope fixed to the fruit tree is higher than the end fixed to the rocking arm 30, so that the angle between the inclined rocking arm 30 and the rope is closer to a right angle, so that when the rocking arm 30 shakes the fruit tree through the rope, the vibration force is greater, and the effect of shaking the fruit tree down is better.

[0043] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
