Problems solved by technology
[0005] At present, there are structural contradictions in harvesting machinery in the production process of tuber crops in my country, and the effective supply is insufficient; there are many small machinery and tools, and large and medium-sized agricultural machinery and tools cannot keep up with the development needs; there are not many types and specifications of machinery, and the quality and performance are unstable. Insufficient research and development efforts; there are weak or even blank links in mechanical operations, which do not meet the needs of strategic adjustment of agricultural and rural economic structures; there are serious problems such as aging machinery and tools, low technical level, and insufficient investment in renewal.
Harvesting machinery cannot meet the actual needs of tuber crop production, which directly affects farmers' enthusiasm for planting and purchasing machinery

Embodiment Construction
[0021] A high-efficiency spiral screening machine invented and designed is a new mechanical technology integrating lifting, screening, crushing, separation and transportation. according to figure 2 As shown, the position of each device in the high-efficiency spiral screening machine is in order from outside to inside: frame→supporting wheel→gear→outer spiral screen→screw guide plate→triangular crusher→built-in feeder.
[0022] according to figure 1 and figure 2 The function of the label name is introduced as follows:
[0023] The spiral material guide plate is a long strip material. The spiral material guide plate is between the built-in feeder and the outer spiral screen, and is wound along the outer side of the built-in feeder and the inner side of the outer spiral screen with a certain distance. become. The spiral material guide plate is connected with the inner side of the outer spiral screen, and not connected with the built-in feeder, and the width of the spiral ma...

Abstract
The invention relates to an efficient spiral screening machine and belongs to the technical field of agricultural machinery. A spiral guide plate between a built-in loader and an outer surface spiral screen is used for centrifuging to separate and remove impurities during material lifting. By gradual pushing of the spiral guide plate, materials glide to a triangular smasher under the gravity after being lifted to be smashed inertially, and the delivery of the materials in the spiral screening machine is completely gliding. Lifting, screening, smashing, separation and delivery are integrated, and different crops are harvested. By means of the screening machine, a novel mechanical transmission mode is added in the delivery field, the screening machine can be used for design of other crop harvesters, functions of traditional crop harvesters are surpassed greatly, and the prior crop harvester mechanical design ideal is broken.
Description
Technical field: [0001] The invention relates to a high-efficiency spiral screening machine, which belongs to the technical field of agricultural machinery. Background technique: [0002] All kinds of crops planted in my country include food crops and economic crops. From the perspective of planting space, more and more underground crops are paid more attention, such as oily beans, potatoes, sweet potatoes, yams, taro, Jerusalem artichoke, garlic, onions, Chinese herbal medicines, etc., can be used as food for human consumption, feed for animals, and can also be used for starch, wine making, and medicinal purposes. They are widely used in food and non-food industries, and their development prospects are broad. Especially underground tuber crops, such as oily beans, peanuts, etc., have high yields and store rich nutrients. [0003] At present, the harvesting method of tuber crops in most areas in China is still mainly manual harvesting, some areas use digging plows, and a few...
