Technical Field

[0001] This utility model relates to a harvester for root and tuber crops. Background Technology

[0002] Chinese Patent No. 202010540317.X discloses a root crop harvester and harvesting method. The invention employs a sorting device including a sorting conveyor and a first conveyor. The sorting conveyor is positioned above the first conveyor, with its rear end inserted into a ring-shaped lifting conveyor. The front end of the first conveyor extends in front of the sorting conveyor, and its rear end is located behind the ring-shaped lifting conveyor. The sorting conveyor's conveying direction is from back to front, while the first conveyor's conveying direction is from front to back. A workbench is provided on at least one side of the frame of the machine. During harvesting, as the sorting conveyor carries the material forward, operators standing on both sides of the sorting conveyor pick up the crops and bag them on the workbench. The bags filled with crops are pushed directly onto the first conveyor from the workbench. Other debris on the sorting conveyor also falls onto the first conveyor from its front end. The bagged crops and other debris are then transported by the first conveyor to the field behind the harvester.

[0003] The crops sorted by this root crop harvester need to be bagged on the machine and then transported to the rear of the machine via the first conveyor. The processing speed is slow and it is not easy to collect the crops.

[0004] To facilitate crop collection, there is currently a situation where harvesters and follower vehicles are used in combination. The harvester is equipped with a conveyor that transports the harvested crops directly to the follower vehicle. However, there is a problem: since the follower vehicle can only follow the side where the crops have been harvested, the harvester needs to make cross-row turns or other means to avoid the follower vehicle trampling on the unharvested crops. Because it cannot make cross-row turns, there are empty trips. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a root crop harvester that is easy to collect crops, so that it can turn around and harvest adjacent rows while keeping the follow vehicle following to collect crops.

[0006] To solve the above-mentioned technical problems, this utility model includes a frame and a traveling device. The frame is equipped with an excavating device and a conveying device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 like Figure 1 -3 shows a root crop harvester that facilitates crop collection. It includes a frame 4 and wheels 5. The frame 4 is equipped with a digging device 1, a chain-type lifting conveyor 2, a chain-type vibrating conveyor 3, and a ring-shaped lifting conveyor 7 arranged sequentially from front to back. The digging device 1, the chain-type lifting conveyor 2, the chain-type vibrating conveyor 3, and the ring-shaped lifting conveyor 7 are connected in sequence. The rear end of the chain-type vibrating conveyor 3 is inserted into the ring-shaped lifting conveyor 7. The frame 4 is also equipped with a sorting device. The digging device 1, the chain-type lifting conveyor 2, and the chain-type vibrating conveyor 3 are located below the sorting device. The sorting device includes a sorting conveyor 10 and a first conveyor 9. The sorting conveyor 10 and the first conveyor 9 are arranged in two layers from top to bottom. Both the sorting conveyor 10 and the first conveyor 9 are inserted into the ring-shaped lifting conveyor 7. The front ends of the sorting conveyor 10 and the first conveyor 9 extend to the front side of the ring-shaped lifting conveyor 7. The sorting conveyor 10 conveys from back to front, the first conveyor 9 conveys from front to back, and the frame 4 has workbenches 8 on both the left and right sides of the sorting device.

[0020] An auxiliary conveyor 15 is installed inside the annular lifting conveyor 7. The auxiliary conveyor 15 is located on the side of the top of the annular lifting conveyor 7 in the material inflow direction relative to the sorting conveyor 10. The material output end of the auxiliary conveyor 15 is connected to the sorting conveyor 10. This allows the auxiliary conveyor 6 to catch the material falling from the top of the annular lifting conveyor 7 and transfer it to the sorting conveyor 10.

[0021] This embodiment makes the following improvements based on the prior art: a second conveyor 11 is added, and a drive system 12 for driving the walking wheels 5 is provided on the frame 4.

[0022] The second conveyor 11 includes a conveyor frame 11-2, an annular conveyor belt 11-3, support rollers 11-4, and drive wheels 11-1. The conveyor frame 11-2 is mounted on the frame 4. The support rollers 11-4 and drive wheels 11-1 are rotatably mounted on the conveyor frame 11-2. The annular conveyor belt 11-3 is supported in a V-shape by the support rollers and drive wheels. A power device that controls the forward and reverse rotation of the drive wheels 11-1 is installed on the conveyor frame 11-2. There are two drive wheels 11-1, located at opposite ends of the V-shape.

[0023] The front end of the first conveyor 9 is located after the front end of the sorting conveyor 10, and the rear end of the first conveyor 9 is located after the annular lifting conveyor 7. Alternatively, a chute can be installed in the annular lifting conveyor 7 with its discharge section located after the annular lifting conveyor 7, and the first conveyor 9 connects to this chute. The middle part of the second conveyor 11 is located below the front end of the sorting conveyor 10. The middle part of the second conveyor 11 is used to receive the material output from the front end of the sorting conveyor 10. Both ends of the second conveyor 11 extend to the left and right sides of the frame 4, allowing the harvester to collect crops from both sides.

[0024] Example 2 The difference between Example 2 and Example 1 is as follows: As shown in Figure 4, a chute 13 is provided between the workbench 8 and the sorting conveyor 10. The chute 13 has a certain gap with the side of the sorting conveyor 10, and the discharge part of the chute 13 is located on the first conveyor 9.

[0025] The auxiliary conveyor 6 is inverted L-shaped and is located on the top side of the annular lifting conveyor 7 in the material inflow direction relative to the sorting conveyor 10. The material output end of the auxiliary conveyor 6 is connected to the sorting conveyor 10. The vertical part of the auxiliary conveyor 6 forms a baffle device to prevent material lifted on the inflow side of the annular lifting conveyor 7 from falling off. Furthermore, the vertical part of the auxiliary conveyor 6 and the annular lifting conveyor 7 can form a clamping conveyor, which is more conducive to the lifting and conveying of materials.

[0026] Harvesting Method: During harvesting, the harvester is self-driven and moves through the field. A follower vehicle follows the side of the harvester where there are no crops. By controlling the steering of the drive wheels 11-1, the output end of the second conveyor 11 is positioned above the bucket of the follower vehicle. Operators are mounted on two work platforms 8. The digging device 1 extends into the soil to scoop out a certain thickness of soil containing crop roots and stems, which is then sequentially conveyed to the chain-type lifting conveyor 2, the chain-type vibrating conveyor 3, and the ring-shaped lifting conveyor 7. During this conveying process, most of the soil is shaken back into the field, and the crops... Debris such as seedlings and stones are carried to a high position by the ring-shaped lifting conveyor 7, falling onto the auxiliary conveyor 15 and then onto the sorting conveyor 10. As the sorting conveyor 10 carries the material forward, operators standing on both sides of the sorting conveyor pick up the debris and slide it down the chute 13 onto the first conveyor 9. The debris is then transported by the first conveyor 9 to the field behind the harvester. After sorting, the crop falls from the front of the sorting conveyor 10 onto the second conveyor 11, and is then transported by the second conveyor 11 to the following vehicle's bucket. After harvesting one row, the harvester directly turns around to harvest the adjacent row. The following vehicle moves to the other side of the harvester, and the conveying direction of the second conveyor 11 is switched to change the output end. This way, the output end of the second conveyor 11 can remain above the following vehicle's bucket. The second row is harvested using the aforementioned method, and this process is repeated until harvesting is complete.
