Description

Technical Field

[0001] The utility model relates to the technical field of agricultural harvesting machinery, in particular to a potato harvesting device. Background Art

[0002] Potatoes have the characteristics of thin skin, wide adaptability, cold resistance, high yield, and drought resistance, which make them have the potential for increased production. The related industrial chain is also relatively long. It is the fourth largest food in the world. At this stage, relevant departments attach great importance to the development of the potato industry and regard it as the "highlight" to stabilize food production and ensure food security. However, the degree of mechanization of potato planting and harvesting is low, and manual harvesting is usually adopted. The traditional manual harvesting method is often slow, making manual harvesting of potatoes more difficult and expensive, which directly affects the development of potato-related industries to a large extent. Therefore, the planting and harvesting process of potatoes urgently needs to realize high-tech mechanization. Relevant departments should increase their attention to the promotion of mechanization in potato planting and harvesting, take practical and effective measures to solve the problems encountered in actual operations, improve potato production efficiency, and promote the sustainable development of the potato industry. At present, potato harvesting mainly uses small segmented harvesters, which rely on such machinery to realize the functions of digging and laying. However, after the potatoes are dug out by the machine, they still need to be picked up and bagged manually. Although the labor intensity is reduced to a certain extent, the workload is still huge and the labor cost is relatively high. In view of the above situation, it is concluded that the current acquisition of potatoes has the following disadvantages: 1. The stems and leaves of potato crops still rely on manual pruning; 2. Picking potatoes needs to be done manually; 3. The existing harvesters have a single function and require multiple different functions of equipment to work at the same time; 4. When harvesting potatoes, large pieces of soil may be accidentally brought in; 5. The large amount of dust caused by the equipment when working is harmful to the human body; 6. The screening of potato size requires strict manual control. Therefore, in view of the problems existing in the acquisition of potatoes today, it is necessary to propose improvements to the potato acquisition machine. Utility Model Content
