Description

Technical Field

[0001] The invention belongs to the technical field of crop harvesting, and in particular relates to a harvester for root and tuber crops. Background Art

[0002] Root and tuber crops are plants whose main edible part is the root or stem. These crops play an important role in diets around the world, not only because they are an important source of food, but also because they are rich in nutrients, providing a wealth of vitamins, minerals and dietary fiber.

[0003] When harvesting yam, it is necessary to take the mature yam out of the soil. In order to avoid affecting the product quality due to bruises and breaks during harvesting, the traditional method of harvesting yam requires manual deep digging of the soil around the yam and careful operation, which is inefficient. When harvesting yam, the prior art uses a digging knife to vertically dig the soil around the yam downward so that the yam and the surrounding soil are contained in the inner hole of the hollow knife rod. Then the yam will be squeezed in the hollow knife rod by the soil and rise up with the digging knife to leave the underground, completing the harvesting of the yam. However, when harvesting yam in this way, the digging knife will squeeze the yam and the soil outside the yam into the hollow knife rod. In this process, the soil will squeeze the yam. When the soil contains harder lumps of soil or stones, the surface of the yam is easily damaged by the lumps of soil or stones, affecting the quality of the yam. At the same time, after taking out the yam, the staff is required to clean the soil carried on the outside of the yam. The steps are cumbersome, which greatly reduces the harvesting efficiency and reliability of the yam.

[0024] Specifically, the vibration plate 119 can be used to separate the yam from the soil adhered to the surface of the yam, avoiding the need for workers to clean the soil on the outside of the yam after taking out the yam, thereby greatly improving the harvesting efficiency and reliability of the device when harvesting yam.

[0025] The operating principle of the present invention is now described as follows: In the present invention, when it is necessary to harvest the yam, the collecting cylinder 7 is moved to the top of the yam to be harvested through the two movable bottom plates 1, so that the middle position of the collecting cylinder 7 is located directly above the yam, and then the first electric slide rail 3 is controlled to start, driving the first slide plate 4 to move downward, so that the collecting cylinder 7 is close to the soil surface, and then the first motor 96 is controlled to start, driving the first round rod 95 to rotate, so that one end of the second electric telescopic rod 97 is directed toward the yam, and then the second electric telescopic rod 97 is controlled to start, driving the second U plate 98 and the bucket 912 to move toward the yam. After the pressure sensor 914 contacts the outer wall of the yam, the pressure sensor 914 detects pressure at this time, indicating that the bottom end of the bucket 912 is about to approach the outer wall of the yam, and the first electric telescopic rod 6 drives the bucket 912 to move toward the yam. During the movement of the bucket 912 toward the yam, the second motor 910 is controlled to start continuously to drive the second round rod 99 to rotate so that the bottom end of the bucket 912 can always be in contact with the ground. Then, the first motor 96 is controlled to start to drive the first round rod 95 to rotate in the opposite direction. During the rotation of the first round rod 95, the second electric telescopic rod 97 is controlled to extend so that the bucket 912 moves toward the soil next to the yam. As the first round rod 95 rotates, the bucket 912 will dig the soil next to the yam to the outside of the collection tube 7. During this process, the second motor 910 is controlled to start continuously, and the angle of the bucket 912 is continuously adjusted by using the second round rod 99, so that the bottom end of the bucket 912 can always maintain the same angle during the contact with the soil, which is convenient for digging the soil into the collection tube 7. On the outside, after multiple buckets 912 have excavated the corresponding soil to one side, the second electric slide rail 92 is controlled to start, driving the second slide plate 93 to move, so that the bucket 912 moves to other positions of the soil outside the yam to excavate the soil. After the bucket 912 has excavated the soil to the outside of the collecting tube 7, the bucket 912 will rotate toward the inside of the collecting tube 7. At this time, the fourth electric telescopic rod 106 is controlled to start, so that the bottom end side wall of the push plate 107 contacts the soil surface. Then, the third electric telescopic rod 104 is controlled to start, driving the push plate 107 to move toward the soil outside the collecting tube 7, and the soil excavated by the bucket 912 is pushed to prevent the soil from falling around the yam again. The third electric slide rail 102 is controlled to drive the third slide plate 103 to move, so that the push plate 107 can After the bucket 912 excavates the soil, the excavated soil is compacted in time. After the bucket 912 excavates a layer of soil around the yam, the first electric slide rail 3 is controlled to start, and the first slide plate 4 is used to drive the collecting tube 7 to move downward, so that the bucket 912 continues to excavate the soil around the yam. After a part of the surface of the yam is exposed, one of the fourth electric slide rails 112 is controlled to start, and the fourth slide plate 113 is driven to move, so that the fourth slide plate 113 is evenly distributed on one side of the exposed part of the yam, and then the corresponding fifth electric telescopic rod 114 is controlled to start, so that the arc plate 115 is close to the yam, and then the corresponding sixth electric telescopic rod 117 is controlled to start, so that the corresponding vibration plate 119 contacts the outer wall of the yam, and then the vibration motor 118 is controlled to start.The vibration plate 119 is driven to vibrate continuously to vibrate the soil adhered to one side of the yam, and then the fourth electric slide rail 112 on the other side is controlled to start, and the soil adhered to the other side of the yam is processed according to the above steps. After the yam is continuously exposed to the outside, the top fourth slide plate 113 is controlled to remain motionless, and then the bottom fourth slide plate 113 is located on the side of the bottom end of the yam exposed to the outside, and then the middle multiple fourth slide plates 113 are always arranged equidistantly, and the vibration plate 119 is used to continuously process the soil adhered to the surface of the yam to separate the yam from the soil. With the continuous excavation of the soil around the yam, when the first slide plate 4 moves to the lowest end, the first electric telescopic rod 6 is controlled to drive the collecting tube 7 to continue to move downward, and the soil around the yam is excavated. The soil around the yam is excavated. After the soil around the yam is excavated and the bottom of the yam leaks out, the fifth slide plate 123 at the uppermost end of the fifth electric slide rail 122 is controlled to start, so that the clamping plate 125 is located on one side of the uppermost end of the yam. Then, the fifth slide plate 123 at the lowermost end of the fifth electric slide rail 122 is controlled to start, so that the fifth slide plate 123 moves to the lowermost end. Then, the seventh electric telescopic rod 124 is controlled to start, and the yam is clamped by the clamping plate 125. Then, multiple fifth slide plates 123 are controlled to move upward at the same time, driving the yam to move upward. When the fifth slide plate 123 at the uppermost end moves to the uppermost part of the fifth electric slide rail 122, the seventh electric telescopic rod 124 on one side of the fifth slide plate 123 at the uppermost end remains stationary. Then, the other seventh electric telescopic rods are controlled 124 contracts, and the splint 125 is not used to clamp the yam, and then the other multiple fifth slides 123 except the fifth slide 123 at the top are controlled to move downward, and then the corresponding splints 125 are controlled to re-clamp the yam, and then the seventh electric telescopic rod 124 at the top is controlled to contract, so that the splint 125 does not clamp the yam, and then the other fifth slides 123 are controlled to continue to move upward, driving the yam to move above the collecting tube 7, and the yam is transported to the top of the collecting tube 7 according to the above steps. After the staff receives the upper end of the yam, the splint 125 is not fixed to the yam, and the staff can take out the harvested yam to complete the harvesting of the yam. When the yam needs to be harvested, the bucket 912 can be used to dig out the yam around The soil is excavated to the outside of the collecting tube 7, so that the outer surface of the yam is continuously exposed. As the bucket 912 continuously digs deeper into the soil, the outer surface of the yam is completely exposed to the outside. At this time, the splint 125 is used to transport the yam to the top of the collecting tube 7 to complete the harvest of the yam, and to prevent the digging knife from squeezing the yam and the soil outside the yam into the hollow knife rod, so that the soil squeezes the yam, causing the surface of the yam to be damaged by lumps of soil or stones, affecting the quality of the yam. At the same time, it can drive the push plate 107 to move toward the soil outside the collecting tube 7, and push the soil excavated by the bucket 912 to prevent the soil from falling around the yam again, affecting the harvest of the yam. The vibration plate 119 can also be used to separate the yam from the soil adhered to the surface of the yam, so as to avoid the yam being taken out.The staff is also required to clean the soil outside the yam, which greatly improves the harvesting efficiency and reliability of the device when harvesting yam.
