[0017] Example

[0018] Please refer to Figure 1-Figure 2The utility model proposes a spherical crop harvester vibration device, including two mutually rotating first bar frames 1 and second bar frames 2, a driven gear 3 is rotatably installed between the first bar frame 1 and the second bar frame 2, and the shaft of the driven gear 3 is clamped with the first bar frame 1, and a limiting mechanism 4 is installed on the second bar frame 2, and the limiting mechanism 4 can limit the rotation of the driven gear 3. In the utility model, the limitation of the driven gear 3 is released by the limiting mechanism 4, and the first bar frame 1 is limited by the limiting mechanism 4 after rotating relative to the second bar frame 2, so that there is an angle between the first bar frame 1 and the second bar frame 2. The utility model is connected to the two ends of the rod, and the rod rotates to drive the utility model to rotate, and the ends of the first bar frame 1 and the second bar frame 2 will push the conveyor belt on the harvester at intervals, thereby causing the crops on the conveyor belt to vibrate and shake off the soil on the crops. In the utility model, if the angle between the first strip frame 1 and the second strip frame 2 is different, the frequency of the jacking conveyor belt will change, and if the angle between the first strip frame 1 and the second strip frame 2 is different, the height of the conveyor belt will also be different, thereby changing the vibration amplitude of the conveyor belt.

[0019] In a specific embodiment, refer to Figure 1 , Figure 2 The limiting mechanism 4 includes a transmission gear 41, a limiting block 42 and a sliding rod 43. The limiting block 42 is fixed to the sliding rod 43 and is slidably installed on the second strip frame 2 through the sliding rod 43. The transmission gear 41 is installed on the second strip frame 2 and is located between the driven gear 3 and the limiting block 42. The transmission gear 41 and the driven gear 3 are meshed with each other, and the limiting block 42 can slide through the sliding rod 43 to limit the rotation of the transmission gear 41; in the utility model, the sliding rod 43 is pulled outward to disengage the limiting block 42 from the transmission gear 41. At this time, the driven gear 3 will also release the restriction, and the first strip frame 1 is rotated to change the angle between the first strip frame 1 and the second strip frame 2, and the transmission gear 41 is restricted when the limiting block 42 is released.

[0020] In a specific embodiment, refer to Figure 1 , Figure 2 The second strip frame 2 is provided with an installation box 22, and a slot 221 facing the transmission gear 41 and for installing the limit block 42 is provided in the installation box 22, and a column slot 222 for installing the slide bar 43 is connected to the slot 221. The slot 221 in the installation box 22 can provide a guide for the limit block 42, and the column slot 222 provides a guide for the slide bar. The slot 221 in the utility model can limit the rotation of the limit block 42, and further, the slide bar can also be an angular column to limit the rotation of the limit block 42.

[0021] In a specific embodiment, refer to Figure 1 , Figure 2The slide bar 43 is covered with an elastic member 44 and is located in the column groove 222. The two ends of the elastic member 44 respectively contact the limit block 42 and the installation box 22. The elastic member 44 in the utility model can store force when the slide bar 43 is pulled outward. When the slide bar 43 is released, the elastic member 44 drives the limit block 42 to clamp the transmission gear 41 and limit the rotation of the driven gear 3, thereby limiting the rotation of the first strip frame 1. Furthermore, the transmission gear 41 in the utility model can increase the position of the limit mechanism 4, which is convenient for manual adjustment.

[0022] Furthermore, the elastic member 44 can also provide a contact point for the elastic member 44 by installing a limit plate on the slide bar 43, and the limit plate is connected to the slide bar 43, and the two ends of the elastic member 44 respectively contact the limit plate and the installation box 22.

[0023] In a specific embodiment, refer to Figure 1 , Figure 2 The limit block 42 is provided with a tooth key 421 facing the transmission gear 41, and the tooth key 421 of the limit block 42 is meshed with the transmission gear 41. The tooth key 421 on the limit block 42 can increase the clamping effect on the transmission gear 41.

[0024] In a specific embodiment, refer to Figure 1 , Figure 2 , the two ends of the first bar frame 1 are at the same distance from the axis of the driven gear 3. The two ends of the first bar frame 1 are at the same distance from the axis of the driven gear 3 so that the weight on both sides of the axis can be the same, avoiding eccentricity during rotation. Furthermore, in the present invention, two limit mechanisms 4 can be installed on the second bar frame 2 to balance the weight distribution on the second bar frame 2, avoiding eccentric rotation.

[0025] In a specific embodiment, rollers can be rotatably mounted on both ends of the first bar frame 1 and the second bar frame 2, and the rollers are in contact with the transmission belt.
