[0002] The automatic dahlia tuber harvesting device integrates digging and conveying functions. Its digging component can penetrate deep into the soil to dig out the tubers; the conveying component is responsible for transporting the tubers to the designated location, greatly improving harvesting efficiency and reducing the burden of manpower.

[0003] In the prior art, the automatic dahlia tuber harvesting device digs out the dahlia tubers from the soil and transports them to a storage box via a conveying component.

[0004] However, existing automatic dahlia tuber harvesting devices transport dahlia tubers directly to storage boxes without sorting or classifying them, requiring personnel to sort them by size later. Furthermore, the collected materials still contain a large amount of soil, making them inconvenient for personnel to use. Utility Model Content

[0028] In practical use, the upper baffle 19 and the lower baffle 20 respectively block the upper feed port 17 and the lower feed port 18. When the dahlia tubers on the conveying structure installed in the main body 1 of the automatic harvesting device fall onto the guide plate 2, the guide plate 2 guides the dahlia tubers to fall into the upper screen plate 12 installed in the storage box 3. The servo high-frequency fast electric cylinder 7 is activated to push the lower screen plate 8 and the connecting plate 9 to shake up and down, working together with the upper screen plate 12 and the lower screen plate 8 to perform screening. This application aims to protect an automatic harvesting and sorting device for dahlia tubers. Its key feature is that it can automatically sort dahlia tubers during the collection process, thereby reducing the workload of personnel. Other related mechanisms of the automatic harvesting device, such as the harvesting mechanism, have been widely used in the prior art, such as tuber harvesters. This application does not focus on these mechanisms, so they are hidden in the attached drawings. This application is specifically aimed at solving the problem of debris cleaning without affecting the basic function of the automatic harvesting device.

[0029] Example 2

[0030] Based on Embodiment 1, in order to classify the collected dahlia tubers by size, a servo high-frequency fast electric cylinder 7 is provided.

With the help of the connecting plate 9, the upper sieve plate 12 shakes together with the lower sieve plate 8. The dahlia tubers are screened through the upper sieve plate 12. Smaller dahlia tubers and impurities such as soil fall down to the lower sieve plate 8 through the holes. With the shaking of the lower sieve plate 8, the soil and other impurities fall down through the holes opened on the lower sieve plate 8. Through the above, the device can simultaneously classify the collected dahlia tubers by size during operation, and can effectively reduce the amount of soil and other impurities in the collected materials, which is convenient for subsequent cleaning work.

[0033] Example 3

[0034] Based on Embodiment 2, a storage tank 3 is provided to improve the effectiveness of the device. The storage tank 3 has a discharge port 6 on its side, and an upper inlet 17 and a lower inlet 18 inside. An mounting plate 4 is bolted to the side of the storage tank 3.

The lower slot 16 has a square slot structure. The lower connecting hole 15 has a circular hole structure and the upper slot 14 has a square slot structure. The upper baffle 19 slides into the upper slot 14, and the connecting rod 21 slides along the lower connecting hole 15, so that the lower baffle 20 slides into the lower slot 16, thus exposing the upper feed port 17 and the lower feed port 18, allowing the lower screen plate 8 and the upper screen plate 12 to fall into the slot as shown in the example. Figure 2 In the left inner cavity of the storage box 3 shown, personnel can remove the dahlia tubers through the discharge port 6 by removing the mounting plate 4.

[0037] In actual use, the upper feed port 17 and the lower feed port 18 are blocked by the upper baffle 19 and the lower baffle 20 respectively. When the dahlia tubers on the conveyor structure installed in the main body 1 of the automatic harvesting device fall onto the guide plate 2, the guide plate 2 guides the dahlia tubers to fall into the upper screen plate 12 installed in the storage box 3. The servo high-frequency fast electric cylinder 7 is activated to push the lower screen plate 8 and the connecting plate 9 to shake up and down. Together with the upper screen plate 12 and the lower screen plate 8, they are screened for size classification, so that soil and other impurities fall through the holes opened on the lower screen plate 8. In this way, the device can simultaneously classify the collected dahlia tubers by size during operation, and can effectively reduce the amount of soil and other impurities in the collected material, which is convenient for subsequent cleaning work.
