Abstract
The invention discloses a soil sieving device, which is characterized in that a liftable soil taking shovel is arranged at the front part of a frame of a wheel type walking vehicle; a soil convey device is arranged behind the soil taking shovel; a soil sieving device is connected with the rear part of the soil convey device; a coarse material outlet of the soil sieving device is connected with a disposal container; the soil taking shovel is arranged on the wheel type walking vehicle; when the wheel type walking vehicle walks, the soil taking solve shovels the soil containing crushed mulching films; the soil is forced into the soil convey device under pushing of unceasingly coming soil on the shovel when the wheel type walking vehicle advances; then the soil is conveyed into the soil sieving device through the soil convey device, crushed mulching films and sundry are sent to the disposal container, and the purified soil falls back on the fields through the soil sieving device. Due to the adoption of the technical scheme, the mulching films can be cleaned completely, medicine bottles and other sundries in the soil can be cleaned at the same time, as a result, the problem that fine mulching films can not be picked up and the soil is polluted is radically solved, and the goal of keeping a green cropland is achieved.
Description
Technical field
The present invention relates to a kind of soil sieve separating device for reclaiming mulch film purification soil, belong to the plant equipment field.
Background technology
Film-mulching cultivation technique is introduced into China in the seventies in last century.Mulch film is a kind of plastic film, spreads it, can heat, moisturizing, soil conservation, fertilizer conservation, insect protected etc.Especially have significant effect of increasing production in the arid area, become a core technology of China's dry farming.Over nearly two, 30 years, China's plastic mulching area and usage amount occupy the first in the world always, and according to " Chinese agriculture statistics " measuring and calculating, National Agricultural plastic film annual turnover reached 118.4 ten thousand tons in 2010, and area coverage reaches 3.5 hundred million mu; National plastic tunnel plastic film annual turnover was approximately 1,000,000 tons in 2011, and area coverage reaches more than 5,440 ten thousand mu.
Eighties of last century is since the eighties, and the west areas such as Xinjiang begin to promote the use of film-mulching technique on a large scale on cotton, corn, growing vegetables, so that crop yield increases substantially.After entering for 20th century, the modern agriculture take " under-film drip irrigation " technology as representative, the growth record that continues refreshing various crop yields.The collection plastic film mulch, sow, tillage method that fertilising, irrigate band are laid in one, not only saved precious water resource, also so that a large amount of farmland inferior, no longer cultivated farmland become the high-yield field, become " magic weapon " of various places, the Northwest increasing peasant income.
But a lot of people are perhaps unexpected, and the mulch film that can increase production also can bring harm.Along with the mulch film usage amount increases year by year, the problem that overlay film brings also comes one after another.
The cotton planting district in Xinjiang will be counted in the most serious place of Plastic-film pollution by China at present.The a research report demonstration of announcing in 2008, in the Xinjiang region cotton field, 265.3 kilograms of the average per hectares of mulch film residual quantity, and along with the overlay film time limit is longer, pollute more serious.In Xinjiang, the continuous cotton field of overlay film 10 years, 15 years and 20 years, the mulch film residual quantity is respectively 262 kilograms/hectare, 350 kilograms/hectare, 430 kilograms/hectare, and severe contamination field agricultural mulching residual quantity is up to 597 kilograms/hectare.Is what concept this? generally speaking, if spread mulch film for 1 hectare of soil, usage amount is about 60 kilograms, and 597 kilograms mulch film residual quantity is equivalent to store 10 layers of mulch film in the ground.
These mulch films of being made by polyethylene itself can't be degraded, and it is a large amount of in the ground residual if leave, and these farmlands just might the regrowth crop after a lot of years, and a large amount of mulch films is residual, will affect China's ability of agricultural sustainable development.And more alarmingly be, except impact on agriculture, wrap up in the soil and containing a large amount of white pollutions, can or can not environment, water and soil be worked the mischief, produce more far-reaching influence? at present research work does not also relate to.
According to the research report demonstration that autonomous region academy of agricultural sciences, Xinjiang provides, crop yield is on a declining curve with the increase of residual-film amount.Take cotton as example, when residual-film amount in the soil reached 3.5 kilograms every mu, the underproduction 15% at least.Some agricultural experts point out, in recent years, the technology such as universal fertilization compositions based on earth measurement, high-new water saving are all widelyd popularize in the various places, Xinjiang, but the effect of increasing production of crop is offset by residual film substantially.
If just be on the fragment after also having planting seed, just influential to its germination, the phenomenon of being short of seedling may be very serious, causes the underproduction.Can have influence in addition the migration of moisture and nutrient, influential to the growth of crops root system.According to surveying and determination, the with serious pollution soil of residual film can make wheat yield descend 2%～3%, and corn yield descends about 10%, and output of cotton then descends 10%～23%.
The farmland residual mulching film can also make soil environment worsen, and soil moisture content descends, and weakens drought-resistant ability, causes secondary salinization, hardens and fertility decline, affects crop growth, causes the underproduction.According to surveying and determination, broadcast the seed on residual film, mashed kind of a rate can reach 6.92%, and mashed bud rate reaches 5.17%, and output reduction reaches about 12%.In addition, it also affects the agricultural machinery working quality.
The removing mulch film is mainly hugged by machinery and is taken off at present, manually picks up, and in many places, mulch film is weathered into the nail cover size, can't pick up at all.Because mulch film mainly is that thickness is in 0.008mm and following what is called " ultra-thin mulch film ".This mulch film poor ductility, aging fast, have in addition less than results season will be damaged.Strengthened ground membrane removal difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of soil sieve separating device, can't pick up the problem that the farmland of causing might the regrowth crop after by weathering to solve in the prior art because of mulch film.
