Description

Screw feeder type soil gathering and stirring mechanism and dry harvester

Technical Field

The utility model relates to the technical field of dry harvesting equipment for non-pressure-resistant fruits such as water chestnuts and the like, in particular to an auger type soil gathering and stirring mechanism. In addition, the utility model also relates to a dry harvester comprising the auger type soil gathering and stirring mechanism.

Background

Water chestnut, also called chufa, is one of the characteristic vegetables in China, is usually eaten by underground expanded corms, is oval, and has the diameter of 15-50 mm. The planting of water chestnut is distributed in China, Guangdong, Guangxi, Hunan, Hubei, Jiangxi, Anhui provinces and other provinces, and is distributed in southeast Asia regions.

According to statistics, the planting area of domestic water chestnuts is about 60-70 ten thousand mu, the water chestnuts are generally planted after early rice is harvested, the water chestnuts are harvested from ten-month old to the early rice in the next year, the field acres planted by the water chestnuts are different in size, are small to several minutes and are as large as four or fifty mu. The water chestnut grows in a centralized and flat mode on a plough layer and a position close to a non-plough layer of the field soil, and the total thickness of the water chestnut does not exceed 100mm generally.

The skin of the horseshoe is very fragile, so the force for machine screening is moderate, otherwise the skin is easy to break, and the horseshoe cannot be stored for a long time; the field soil for planting the water chestnut cannot be rolled even if being dried in the sun (the rolling of a rubber track tractor cannot be carried out), otherwise, the water chestnut can be damaged internally, and the storage time cannot exceed one month; the water chestnut washed by the high-pressure water gun can be stored for about one month. And the water chestnut which is harvested in a dry mode and is not rolled can be stored for 4-5 months, and is used for eating, the longer the storage time is, the higher the sweetness is, and the higher the selling price is.

For the harvest of the horseshoe, no complete set of harvesting machines exist at present, and almost all the horseshoe is harvested by a manual or semi-manual mode. The harvesting mode is divided into two types: wet harvesting: manually or mechanically washing with a high-pressure water gun, wherein the water chestnut floats out of the water surface in muddy water, and then is fished out by a net bag manually or mechanically; dry harvesting: before harvesting, dry water is discharged; cutting off the seedlings and leaves above the ground, drying the soil to crack by the sun, manually turning the soil open, and manually picking up the soil.

The cost for manually harvesting the water chestnut is high, and the harvesting cost per mu of field is not less than 3000 yuan; the harvest is not thorough, and the waste is at least 10%; furthermore, the harvest of the water chestnut is in winter and the weather is cold, which further increases the difficulty of manual harvest.

Therefore, a fully-mechanized dry type horseshoe harvesting mode is urgently needed to be found, manpower is required to be replaced comprehensively, and the horseshoe is not rolled in the harvesting process, so that the storage time and the economic value of the horseshoe are improved, and the user needs are met.
