[0052] See Figures 1 to 5 This embodiment provides a potato vine separation mechanism, including a frame 10, a conveyor belt 20, a first electric roller 30, and a vine guiding mechanism 50.

[0053] A conveyor belt 20 is laid transversely on the frame 10. The conveyor belt 20 has an inlet end 22 and an outlet end 21, and the conveying direction is from the inlet end 22 to the outlet end 21. The conveyor belt 20 is used to convey potatoes with vines attached. The two ends of the first electric roller 30 are connected to the frame 10. The first electric roller 30 is located below the outlet end 21. The first electric roller 30 and the outlet end 21 of the conveyor belt 20 are close to each other and have the same direction of movement. A vine-clamping gap 40 is formed between the first electric roller 30 and the outlet end 21 of the conveyor belt 20. A vine-guiding mechanism 50 is located at the outlet end 21 of the conveyor belt 20. The vine-guiding mechanism 50 is used to guide the vines on the potatoes conveyed by the conveyor belt 20 to the vine-clamping gap 40. Specifically, the size of the clamping slit 40 is small, which does not allow potatoes to pass through. When the potato vines enter the clamping slit 40, they are pushed into the clamping slit 40 by the upper conveyor belt 20 and the lower first electric roller 30 at the same time.

[0054] In this embodiment, the vine-guiding mechanism 50 guides the potato vines conveyed by the conveyor belt 20 to the vine-clamping slot 40, thus pushing the vines into the slot. Some potatoes separate from the vines due to the inertia generated during conveying by the conveyor belt 20, while others that remain attached to the vines cannot pass through the slot and are separated from the vines at the opening of the slot 40. The conveyor belt 20 can continuously convey potatoes with vines for vine separation, thereby achieving continuous operation and improving separation efficiency.

[0055] In one embodiment, the potato vine separation mechanism further includes a second electric roller 60.

[0056] The two ends of the second electric roller 60 are connected to the frame 10. The second electric roller 60 is located below the discharge end 21 of the conveyor belt 20. The second electric roller 60 is arranged parallel to the first electric roller 30. The second electric roller 60 and the discharge end 21 of the conveyor belt 20, which are close to each other, have opposite directions of movement. Specifically, as shown... Figure 4 The discharge end 21 of the conveyor belt 20 rotates clockwise, and the second electric roller 60 also rotates clockwise. The movement directions of the discharge end 21 and the second electric roller 60 at their closest points are opposite. The first electric roller 30 rotates counterclockwise, which causes its upper end and the lower end of the conveyor belt 20 to move to the left (in the same direction). The first electric roller 30 and the second electric roller 60 are arranged sequentially along the conveying direction of the conveyor belt 20.

[0057] In this embodiment, potatoes with vines on the conveyor belt 20 are guided by the vine-guiding mechanism 50, and the vines are pushed into the vine-clamping slot 40, while the potatoes fall onto the second electric roller 60. The second electric roller 60 rotates in the opposite direction to the first electric roller 30, so that the second electric roller applies external force to the potatoes, causing the potatoes and vines to be separated to both sides by force. In addition, as Figure 4 In the middle, the second electric roller 60 rotates clockwise, which can reduce the chance of potatoes being rolled into the conveyor belt 20 and the second electric roller 60 and being squeezed, thus improving the appearance of the potatoes.

[0058] In one embodiment, the seedling guiding mechanism 50 includes a mounting rod 51 and a seedling guiding assembly 52.

[0059] The two ends of the mounting rod 51 are connected to the frame 10. The mounting rod 51 is located above the discharge end 21 of the conveyor belt 20 and is parallel to the first electric roller 30. Multiple sets of seedling guide components 52 are provided and are evenly distributed along the length of the mounting rod 51.

[0060] The seedling guiding assembly 52 includes a seedling guiding rod 521; the upper end of the seedling guiding rod 521 is rotatably connected to the mounting rod 51, and the lower end of the seedling guiding rod 521 is bent and adapted to the shape of the discharge end 21 of the conveyor belt 20. The discharge end 21 of the conveyor belt 20 is located between the feed end 22 of the conveyor belt 20 and the lower end of the seedling guiding rod 521. Specifically, as shown... Figure 3 The conveyor belt 20 has an approximately elliptical cross-section, and the discharge end 21 (right end) of the conveyor belt 20 has an approximately semi-circular cross-section. The lower end of the guide rod 521 is curved into an arc shape and is located to the right of the discharge end 21 of the conveyor belt 20. When the guide rod 521 has a certain weight, the entire guide rod 521 hangs on the mounting rod 51, and the lower end of the guide rod 521 is not easily knocked open by the potato vines.

[0061] In this embodiment, potatoes with vines attached are conveyed to guide rods 521 on the conveyor belt 20. Potatoes can pass through the space between adjacent guide rods 521, while the vines connected to the potatoes, due to their large size and dispersed stems, are blocked by the guide rods 521. The vines slide down the lower end of the guide rods 521 to the opening of the clamping slot 40 formed by the conveyor belt 20 and the first electric roller 30. As the vines continue to move down the guide rods 521 from the conveyor belt 20, the ends of the vines come into contact with the first electric roller 30 and are fed into the clamping slot 40. At this time, the first electric roller 30 and the lower side of the conveyor belt 20 pull the vines together, thereby separating the potatoes from the vines. The guide rods 521 also complete their function of guiding the vines. In addition, when the potato hits the guide rod 521, the guide rod 521 can also rotate slightly to release the potato, and then the lower end of the guide rod 521 will approach the discharge end 21 of the conveyor belt 20 again under its own weight to guide the potato vine.

[0062] In one embodiment, the seedling guiding mechanism 50 further includes a stop bar 53. The two ends of the stop bar 53 are connected to the frame 10. The stop bar 53 is located between the discharge end 21 of the conveyor belt 20 and the mounting rod 51. The stop bar 53 is parallel to the mounting rod 51 and can abut against multiple seedling guiding rods 521.

[0063] The seedling guide assembly 52 also includes an installation sleeve 522, a counterweight rod 523, and a counterweight rod 524.

[0064] The mounting sleeve 522 is coaxially and rotatably mounted on the mounting rod 51, and the mounting sleeve 522 is connected to the upper end of the guide rod 521. One end of the counterweight rod 523 is connected to the mounting sleeve 522, and the other end of the counterweight rod 523 extends laterally, with the counterweight block 524 connected to the counterweight rod 523.

[0065] In this embodiment, under the counterweight 524, the middle part of the guide rod 521 abuts against the stop rod 53. At this time, the lower curved part of the guide rod 521 maintains a slight distance from the discharge end 21 of the conveyor belt 20, so that the guide rod 521 does not interfere with the conveyor belt 20. Under the counterweight 524, the potato vines are not easily pushed away from the guide rod 521 and fall off the conveyor belt 20. This allows the potato vines to be guided by the guide rod 521 to the first electric roller 30. When the counterweight 524 is set, the guide rod 521 does not need to be specially set to a heavier type.

[0066] In one embodiment, the conveyor belt 20 includes a third electric roller 23, a drive gear 24, a driven sleeve 25, a transmission belt 26, and a conveyor rod 27.

[0067] The third electric roller 23 is connected to the frame 10 at both ends. Two drive gears 24 are provided, each sleeved onto the third electric roller 23. Two driven sleeves 25 are provided, both rotatably mounted on the frame 10. Specifically, the third electric roller 23 is located between the driven sleeves 25 and the lower end of the guide rod 521. A coaxial limiting disc 28 is connected to the outside of the driven sleeve 25.

[0068] Two drive belts 26 are provided, each in a loop shape. One end of each drive belt 26 is fitted onto a driven sleeve 25, and the other end of each drive belt 26 is fitted onto the third electric roller 23 and located outside the corresponding drive gear 24. Specifically, the opposite sides of the two drive belts 26 can abut against the limiting disc 28, thus being limited; the opposite sides of the two drive belts 26 can abut against the opposite sides of the two drive gears 24, and the drive gears 24 and the limiting disc 28 limit the two drive belts 26. Multiple conveying rods 27 are arranged in parallel, with each end of the conveying rod 27 connected to one of the two drive belts 26, and the conveying rods 27 are evenly distributed on the drive belts 26. The conveying rods 27 can be embedded into the tooth grooves of the drive gears 24. The position of the third electric roller 23 is the discharge end 21 of the conveyor belt 20, and the position of the driven sleeve 25 is the feed end 22 of the conveyor belt 20. In addition, the conveyor belt 20 can also be in the form of two sets of sprockets driving two parallel chains to rotate, with conveyor rods 27 connected to the chains. The two sets of sprockets are connected by two rods, and one of the rods can be driven to rotate by a motor.

[0069] In this embodiment, the rotation of the third electric roller 23 drives the rotation of the drive gear 24, which in turn moves the conveyor rod 27 embedded in the drive gear 24, thereby moving the two transmission belts 26. Potatoes with vines are placed on the conveyor rods 27 for transport. After passing the lower end of the guide rod 521, the potatoes are positioned on the second electric roller 60, while the vines are limited by the guide rod 521. Since the conveyor rods 27 are evenly spaced, the portion of the vines blocked by the guide rod 521 enters between adjacent conveyor rods 27. This portion of the vines is then carried and rotated to the first electric roller 30 before entering the vine-clamping gap 40 and being transported away. In other words, the conveyor belt 20 uses evenly spaced conveyor rods 27, making it easier for the vines on the potatoes to be carried into the vine-clamping gap 40, reducing interference from the rotation direction of the second electric roller 60, thus separating the potatoes from the vines and improving efficiency.

[0070] In one embodiment, the potato vine separation mechanism further includes two baffles 70 connected to the frame 10, with the two baffles 70 located on the outer side of the transmission belt 26. The baffles 70 extend along the conveying direction of the conveyor belt 20. By setting the baffles 70, potatoes along with their vines can be prevented from falling off the side.

[0071] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
