Description

Sweep along formula pole jack

Technical field

It is that one kind sweeps along formula pole jack the utility model relates to cotton stalk harvesting equipment technical field.

Background technique

Cotton be the major economic crops in China one of, planting area covers China's most area, mainly there is length River basin, Yellow River basin and Xinjiang region, due to the difference in geographical location and weather, the cotton planting feature in each cotton region also has Institute is different, and national cotton sown area in 2016 is 5064.2 ten thousand mu according to statistics, and 534.3 ten thousand tons of national cotton yield, Xinjiang cotton Flower sown area is 24,880,000 mu, and Cotton Yield in Xinjiang reaches 359.4 ten thousand tons, and cultivated area accounts for the 49.1% of the whole nation, yield but oneself Through reaching the 66.4% of the whole nation, there is consequence in national cotton industry.According to producing 400 kilograms of cotton stalks per acre It calculates, annual cotton stalk yield is about 20,000,000 tons.

The traditional utilization mode of cotton stalk is: for cotton stalk by direct chopping and returning, cotton stalk crushes returning to the field to increasing Add the soil organism, culture fertility and retain and conserve soil moisture etc. tool has certain effect, but since cotton stalk surface layer is very hard Firmly, the root lignifying of cotton stalk is higher, and the cotton stalk of chopping and returning should not rot, and culture fertility is ineffective, and serious Under the influence of stubble sow effect, agricultural production is impacted to some extent, at the same cotton stalk have verticillium wilt can by soil Disease is passed, takes next year to, remaining remaining most of stalk is unutilized and is committed to the flames.

However, due to the characteristic of cotton stalk itself papermaking and biomass energy can be applied to, and bring considerable warp Ji benefit, thus the mode of the direct chopping and returning of cotton stalk is limited to the utilization rate of cotton stalk, it cannot achieve cotton stalk certainly The effective use of body benefit, results in waste of resources and economic loss.

On this basis, also developing for the recycling of cotton stalk has corresponding cotton stalk reclaimer, generallys include There are spade cutting type, promotion formula and integration of operation formula, these equipment can harvest cotton stalk, it can recycle, however, its During harvest, often easily mulch is synchronized and is dug, so that mulch be made to mix with cotton stalk, be not readily separated, influences cotton stalk again Utilization efficiency.Especially these equipment be mostly used for compared with wide row away from cotton stalk harvesting, by the constraint of device structure and size, nothing Method is applied to the harvest of narrow row cotton stalk, is especially not used to the cotton of the machine pick cotton cropping pattern of large area in the region of Xinjiang Bar harvest.

Xinjiang region is in northwest China portion, is the key area of Tendency of Agricultural Machinery in Chinaization development, in Xinjiang region cotton It is big to plant yield, and based on cotton harvesting adopted substantially with machine, the harvesting mode that machine adopts mode is also increasing year by year, but machine pick cotton Cropping pattern " short, close, early " the characteristics of, in addition ultra-narrow row plant, cotton stalk hypotelorism, using above equipment be used for cotton When stalk cutting, largely fractureing and leaking phenomena such as pulling out occur in disposable two guilds that harvest, and two rows are separately recovered and there is sky Between can not place, to seriously affect recycling for cotton stalk.

Summary of the invention

The utility model provides one kind and sweeps along formula pole jack, overcomes the defects of the prior art, and can effectively solve Easily mulch is synchronized existing for certainly existing cotton stalk and is dug, so that mulch be made to mix with cotton stalk, is not readily separated, influences cotton stalk The problem of recycling efficiency.
