Description

Potato harvesting plough

Technical Field

The invention belongs to the technical field of agricultural production, and particularly relates to a potato harvesting plough, and more particularly relates to a potato harvesting plough and a using method thereof.

Background

As is known, the planting of all kinds of sweet potatoes and taros is all through planting in the hunch slope of uplift, divides the hunch slope of uplift into one way simultaneously to leave a trench, prevent on the one hand that the rainwater from continuously irrigating, be convenient for fertilize, loosen the soil etc. on the other hand is favorable to the later stage to reap the sweet potato owing to the uplifted loosening soil. The harvesting method of potatoes is common and practical, namely the potatoes are harvested by manual digging, planing and the like. For the harvest of potato agricultural products, a continuous improvement process has been provided for a long time, because the planting scale is smaller for individual farmers, the actual requirements and requirements can be met by manual harvest, but for plain areas and hilly areas, the efficiency is low by manual harvest, and the production scale and requirements are not met. The mechanical harvesting of the sweet potatoes is needed to meet certain harvesting requirements, but the large-scale machine in the sweet potato harvesting process can not be flexibly applied to the direct harvesting process of sweet potato planting areas, because the arch slopes of the sweet potato planting areas in each area are different in size, and the trench between the arch slopes of each area is wide or narrow, the high requirements on harvested farmers are met, meanwhile, certain normative requirements on agricultural machinery of traction equipment are met, and the width of the trench determines whether the agricultural machinery can normally harvest various potato agricultural products.

Among them, chinese patent No. 201810767709.2 describes an excavating plough towed by a tractor, which aims to solve the problem of "intensive transformation of agricultural production and improvement of supply direction at present". People are required to develop the agricultural fertilizer with higher quality and lower cost, and the agricultural fertilizer needs to be comprehensively mechanized and intelligentized to achieve the aim, otherwise, the agricultural fertilizer cannot be comprehensively optimized, and the agricultural fertilizer cannot leave the old way of the traditional agriculture. Use sweet potato medicinal material to plant as an example, if do not take first the realization comprehensive mechanized intellectuality, be the technical problem that can't realize the comprehensive upgrading of agricultural of intensification scale ", but the device is through" screening machine, receiving box, the drive wheel, a section of thick bamboo that climbs, the flight, a section of thick bamboo of discharging, curved "technical characteristics such as can't be nimble go in sweet potato planting ground at all, it is not suitable for to the hilly terrain of north anhui, can not belong to nimble mechanized production simultaneously, bring the burden for changeable results topography. Wherein, chinese utility model patent No. CN99242107.1 describes a suspension type potato harvesting and tilling machine, and the harvesting and tilling machine aims at solving the following problems: when the crops such as potatoes are harvested, the crops are all dug manually, the method has low efficiency and high labor intensity and is not suitable for the technical problem of large-area large-scale production, the crops and the potato harvests are dragged by a tractor, the plough and the blade drive the crops and the potato harvests to one side and fold the crops and the potato harvests to one side, the radial shifting teeth shift the plough and the blade to fold the soil and the potato harvests to one side and drain the soil during the rotation of the shifting gears, and the potato harvests are shifted to the soil surface of one side, so that the working process of the machine is completed. The machine can turn out potato harvests from soil and separate the potato harvests, and can finish field cultivation, thereby having high labor efficiency and greatly reducing the labor intensity of people. However, the harvesting and tilling machine has no supporting mechanism, and the raised soil can be turned over and poked to the raised dam slope on the other side in the harvesting and tilling process, and the soil can be scattered around, so that the sight is influenced, and the harvesting and cleaning work of potatoes is not facilitated. Among them, the chinese patent No. 201610840915.2 describes a potato harvester, which is the closest technical direction to the present invention, and the technical problem to be solved is also that the sweet potato and potato are important crops in agricultural production, and the traditional harvesting method is to dig and plane by manpower, and the defects are: time and labor waste and high labor intensity. However, the specific study finds that the design of the harrow strips in the patent cannot be professionally applied to the harvest requirement of the raised sweet potato planting field, the harvester is inclined to flat ground cultivation, the wide rack cannot walk in a trench on the sweet potato planting field, the two ends of the rack are wide, the rack can be delayed on the peripheral potato planting slope, the depth cannot be controlled even if the middle harrow strips play a digging role, and the potato rooting growth can also penetrate into the lower surface of the trench, so that the harrow strips cannot be used in hilly terrain or high-gradient raised planting terrain. The stress direction of the rake type design is that potatoes are forced out in a rake bar scraping and scraping mode, so that the selling phase of the potato crops with large and small block heads can be seriously damaged, and even the potatoes are crushed.

Therefore, the potato harvesting plough with the innovative structure design provided by the invention better overcomes the defects.
