[0021] This utility model provides an embodiment of a harvesting device 100, which can greatly improve the harvesting rate of the fruit to be harvested during the harvesting process and reduce the probability of damage to the fruit during the harvesting process.

[0022] To facilitate the reader's understanding of the concept of this utility model embodiment, the specific structure of the harvesting device 100 is described below: Please see Figure 1 and Figure 2 The harvesting device 100 includes a collection bin 1, a vibration mechanism 2, and a drive mechanism 3. The collection bin 1 is used to collect the harvested fruits. The vibration mechanism 2 is installed on the collection bin and is used to clamp the branches on which the fruits to be harvested grow and to vibrate the branches so that the fruits to be harvested are separated from the branches. The drive mechanism 3 is installed on the collection bin and connected to the vibration mechanism to drive the vibration mechanism to vibrate.

[0023] For collection bin 1 mentioned above, please refer to Figure 3 The collection chamber 1 includes a first side wall 111, a second side wall 112, a third side wall 113, a fourth side wall 114, and a bottom wall 110. The first side wall 111, the second side wall 112, the third side wall 113, and the fourth side wall 114 are all located on the bottom wall 110. The first side wall 111, the second side wall 112, the third side wall 113, and the fourth side wall 114 are connected end to end in sequence, and the first side wall 111, the second side wall 112, the third side wall 113, the fourth side wall 114, and the bottom wall 110 enclose the chamber. There is a collection trough 11, the first sidewall 111 and the fourth sidewall 114 are arranged opposite to each other, the second sidewall 112 and the third sidewall 113 are arranged opposite to each other, the height of the first sidewall 111 is less than the height of the second sidewall 112, and the height of the first sidewall 111 is also less than the height of the third sidewall 113, so that the collection chamber 1 is recessed at the position of the first sidewall 111. This recess is used for inserting branches, and the first sidewall 111 is also used for mounting a vibration mechanism 2 to vibrate the branches at the recessed position.

[0024] For the aforementioned vibration mechanism, please refer to Figure 4 The vibration mechanism 2 includes a base 21, a plurality of teeth 22 and a connector 23. The base 21 is slidably disposed on the first side wall 111, the plurality of teeth 22 are spaced apart on the base 21, and the plurality of teeth 22 protrude from the first side wall 111 along the first direction x. The connector 23 is connected to the base 21.

[0025] For the drive mechanism 3 mentioned above, please refer to Figure 5 The drive mechanism 3 includes a drive assembly 31 and a transmission shaft 32. The transmission shaft 32 is disposed on the bottom wall 110 of the collection chamber 1. One end of the transmission shaft 31 is connected to the drive assembly 31, and the other end is connected to the adapter 23.

[0026] The branches carrying the fruit can be engaged between several teeth 22. The drive assembly 3 drives the base 21 via the transmission shaft 32 and the adapter 23 to move the teeth 22 back and forth along the second direction y, vibrating the branches and causing the fruit to separate from the branches. Here, the first direction x is the direction from the bottom wall 110 of the collection trough 11 to the opening of the trough, and the second direction y is perpendicular to the first direction x.

[0027] In some embodiments, please refer to Figure 6 The vibration mechanism 2 also includes a vibration table 25, which is connected to the adapter 23 and fixed on the first side wall 111. The vibration table 25 has a groove 251 at one end away from the adapter 23. The cross-sectional shape of the groove 251 matches the cross-sectional shape of the base 21. The base 21 is engaged in the groove 251 and can slide along the groove 251. By setting the base 21 in the groove 251, the direction of movement of the base 21 can be limited, thereby improving the stability of the vibration mechanism.

[0028] In some embodiments, please refer to Figure 6 and Figure 7 The vibration mechanism 2 also includes a reversing assembly 24, which includes an eccentric member 241 and a reversing member 242.

[0033] In some embodiments, the collection chamber 1 is further provided with a flexible protective layer on the inner wall of the collection trough 11. The flexible protective layer has low hardness and provides cushioning protection when the fruit to be harvested separates from the branch and falls into the collection trough 11, reducing the probability of the fruit being damaged due to collision.

[0034] In this embodiment of the invention, the harvesting device 100 includes a collection chamber 1, a vibration mechanism 2, and a drive mechanism 3. The collection chamber 1 is provided with a collection trough 11. The vibration mechanism 2 includes a base 21, several teeth 22, and a connector 23. The base 21 is slidably disposed on a first sidewall 111, and the several teeth 22 are spaced apart on the base 21, with the teeth 22 protruding from the first sidewall 111 along a first direction x. The drive mechanism 3 includes a drive assembly 31 and a transmission shaft 32. The transmission shaft 32 is disposed on a bottom wall 110, and the drive assembly 31 is connected to the base 21 via the transmission shaft 32 and the connector 23. The branches containing the fruit to be harvested are engaged between the teeth 22. The drive assembly 31 drives the base 21 to reciprocate along a second direction y, vibrating the branches and leaves to separate the fruit from the branches. The separated fruit is then directly collected in the collection trough 11, greatly increasing the harvesting rate and reducing the probability of damage to the fruit during the harvesting process.
