But the present inventor studies discovery, there are some defects in the water chestnut harvester of above-mentioned bibliographical information, and one occurs being short of power when being work, easily skids, engine over-emitting black exhaust, and another to be transmission mechanism too much, failure rate of machinery is high; And during their work, all not limiting the earth water content on water chestnut ground, the too high meeting of earth water content in water chestnut ground causes water chestnut to sieve not exclusively and easily causes the damage of water chestnut, affects income.
Summary of the invention
The object of this invention is to provide a kind of utilization percent is high, damage little water chestnut harvesting method and equipment, it is high that harvesting method can reach utilization percent, and speed is fast, does not damage water chestnut; This equipment dynamic foot, cross-country ability are good, smooth ride and failure rate is low.
To achieve these goals, the technical solution used in the present invention is:
The harvesting method of water chestnut of the present invention is dug out from earth by the water chestnut of maturation, and the process be separated with earth, its step comprises:
The first step, the season of gathering in the crops water chestnut, the water in water chestnut field is drained.
Second step, drain water after, plane earth is cut in the stem of water chestnut.
3rd step, plane earth is cut in the stem of water chestnut after, then the airing of water chestnut field to be done to earth water content lower than 20%.Water content, lower than 20%, can be applicable to equipment of the present invention, and past people gather in the crops water chestnut and cause speed slow in the paddy field of non-draining, and utilization percent is low, and damage is serious.
4th step, airing water chestnut field lower than after 20% to earth water content, utilize equipment to be ploughed by water chestnut, and water chestnut and earth are sieved.
5th step, water chestnut and earth are sieved after, utilize sack or frame to be installed by water chestnut, namely complete the results of water chestnut.
The equipment that water chestnut harvesting method adopts is water chestnut harvester, it comprises crawler belt body, earth scraper structure, rotary blade and screen frame, on the right side of crawler belt body, front connects earth scraper structure by support and connection arm, earth scraper structure front upper is provided with rotary blade, earth scraper structure is provided with water conservancy diversion cylinder, and water conservancy diversion cylinder rear lower is provided with screen frame, and screen frame top is connected with screen cloth by screen cloth rocking arm, screen frame is connected with eccentric wheel by rocking arm, and described eccentric wheel passes through pulley drive.
Described earth scraper structure is promoted by hydraulic cylinder, and the convenient height regulating earth scraper structure stably, makes it arrive suitable position, avoids balking and Lou gathers in the crops.
Described rotary blade is by hydraulic motor transmission, and the transmission gear weight of hydraulic motor is light, compact conformation, and inertia is little, and reaction velocity is fast, further less complete machine weight.
Beneficial effect of the present invention is:
1, water chestnut harvesting method of the present invention is drained by the water in water chestnut field, again plane earth is cut in the stem of water chestnut, secondly the airing of water chestnut field is done to earth water content lower than 20%, finally utilize water chestnut harvester to be ploughed by water chestnut, and water chestnut and earth are sieved, the recovery of water chestnut is high, damage is few, damage ratio is low to moderate 5%, and greatly improves the efficiency of crop of water chestnut, reduces cost of labor.
2, the water chestnut harvester that the present invention adopts adopts crawler belt body, and power foot, cross-country ability are good, smooth ride, and transmission mechanism attaching parts are few, and reduce fault rate, maintenance cost is low, and equipment is light and handy, turn convenient.
3, the earth scraper structure upper front end of the water chestnut harvester of the present invention's employing arranges rotary blade, can beat loose topsoil, for earth scraper structure shovel alleviates operation intensity; Earth scraper structure is promoted by hydraulic cylinder, can control earth scraper structure stably and rise or decline, and ensures that water chestnut results are more thorough, effectively reduces labour intensity, provides operating efficiency.
