Description
Technical field
The utility model discloses a kind of crawler type orchard straw covering machine, belongs to field of agricultural equipment and stalk resource is reclaimed
Using field, more particularly to Machinery for orchard equipment field.
Background technology
In recent years, with the adjustment of China's agricultural structure, fruit industry scale fast development, apple, pears, peach, grape, mandarin orange
The cultivated areas such as tangerine have reached the whole world first, and China has turned into state of fruit sparetime university.But China's fruit industry product quality and Industrial Efficiency
There is larger gap compared with developed countries.One important problem is barren orchard soil, excessively using chemical fertilizer, causes soil
Earth is hardened serious.Soil moisture is not only the key factor of soil, plant, atmosphere Continuum, or soil system Nutrient Cycling
With the important carrier of flowing, growth, distribution and the change of ecosystem miniclimate to the characteristic, plant of soil have important
Influence, the Soils In The Region water shortage of arid, semiarid zone and Seasonal Water-Deficit is always the bottleneck problem for restricting the development of fruit industry.
Particularly in northern China arplain and southwest, orchard soil moisture conservation retaining improves soil organic matter content and has become orchard pipe
The most important thing of reason.American-European countries's orchard soil content of organic matter is universal more than 3.0%, Japanese orchard soil organic matter highest
Up to 6.8%, and NORTHWEST CHINA arplain soil organic matter of apple orchards content is universal below 1.0%, and orchard soil is barren have been turned into
One key factor of China's apple production and quality.
Orchard improving straw mulching technology is directed to that orchard soil layer is thin, fertility is low, moisture condition is poor, soil bareness area is big and adopt
The soil management technology for taking.Appropriate crop material etc. is covered on soil exposed around fruit tree, it has soil moisture conservation, section
Water, soil organic matter content, suppression grass, insulation, no-tillage, saving of labor and various effects such as prevent soil loss are improved, soil can be improved
Ecological microenvironment, supports the strong tree of root, promotes Growth status development, and then improve yield and improving quality.Orchard improving straw mulching technology
It is to solve arid, semiarid zone because of the effective measures of rich water shortage restriction orchard upgrading volume increase, is also developing ecology fruit industry, has
One of important production technology of machine fruit industry.
In recent years, stalk technology in orchard is widelyd popularize in China, but due to existing orchard improving straw mulching technical staff
Skill is simple and crude, it is necessary to manual work, time-consuming, and orchard worker worries dry season orchard fire in addition, causes orchard worker's enthusiasm low, pushes away
Wide area is smaller, produces little effect.
Apple Dwarf Stocks intensive culture pattern is the major reform of Apple Culture system, is the main development of world's Apple Culture
Direction.At present, American-European countries a general piece use the intensive efficiency cultivation technology for high of apple dwarf, it is many country short anvil apples accounted for
To more than 90%.Per mu yield is high, and percent rate of high quality fruit height is the advantage that the intensive efficiency cultivation technology for high of apple dwarf is protruded.Abound with phase per mu yield up to 5
More than ton, percent rate of high quality fruit can reach 85%.Comparatively speaking, China is presently mainly tall anvil apple, accounts for 90%, and short anvil apple is only accounted for
10% or so.Therefore, following 10~20 years, China will welcome the high speed development upsurge that an Apple Culture technology upgrading is regenerated.
In recent years, the apple cultivation area such as Shaanxi, Shandong had started to scale introduction.With fruit dwarfing technology, particularly short anvil apple
The advanced technologies such as intensive culture technique are in the popularization of China, and orchard is spacious in the ranks, and tree-like specification will be orchard operation machineryization
Provide convenience.
American-European countries the short general piece in anvil orchard use Cover with weed technology, but research show, Cover with weed technology exist with
Fruit tree strives water and strives the problem of fertilizer, and causes pest and disease damage to increase.Therefore, current Cover with weed technology is not suitable for China orchard, special
It is not drought and water-scarce area.
Therefore, change the simple and crude method of orchard improving straw mulching in the past, study orchard improving straw mulching machineryization technology and develop
Go out orchard improving straw mulching work tool, be the key for playing orchard improving straw mulching technical benefits, be also to realize stalk resource in height
The important channel efficiently utilized in the fruit industry of added value, is to improve orchard soil moisture, the content of organic matter, realizes that orchard high yield is high
The important leverage of effect.
At present, it is fewer in the relevant report of orchard improving straw mulching machineryization technical research and application aspect both at home and abroad.It is existing
There are the patents such as technology such as CN104429384A, CN104429385A, CN204377459U, CN204377363 can solve the problem that existing
Simple and crude, the time-consuming problem of orchard improving straw mulching technical method, promote application of the improving straw mulching technology in orchard, one
Determine to realize orchard soil soil moisture conservation water saving, getting fat, suppression grass, the effect of heat-preserving anti-freezing in degree, reduce operating cost, improve
Fruit industry yield and benefit;Solve orchard surrounding area stalk resource and waste and burn pollution problem.But above technology is also deposited
In place of some shortcomings, its main working parts is to throw the front portion that soil and cutting agency are arranged in whole machine, and being arranged so as to will necessarily
Cause trailer wheel to roll coating, form rut, destroy the integrality of coating, make the soil moisture conservation retaining of coating and suppression
The effect of weeds processed is had a greatly reduced quality;Patent CN205213458U solves the problems, such as that forward type wheel rolls destruction coating, makes
The soil moisture conservation retaining of coating and the effect of suppression weeds give full play to, and improve operation quality, but it throws soil and cutting agency
Position determine that the soil thrown can form intersection-type collision with the stalk of discharge in space, have impact on the uniformity of covering and double
The layered effect of layer covering.Although the self-propelled orchard straw covering machine integrated design such as CN201520598228.5, earthing
The earthing quality of mechanism is difficult to control, stalk hopper finite volume, influences operating efficiency, and overall operation quality also has much room for improvement.
The utility model discloses a kind of crawler type orchard straw covering machine, can comprehensively solve the above problems, and improves operation
Efficiency and quality, promote application of the improving straw mulching technology in orchard, realize orchard soil soil moisture conservation water saving, getting fat, suppression grass, guarantor
Temperature, reduces operating cost, improves operation quality, improves fruit industry yield and benefit;Orchard surrounding area stalk resource is solved to waste
With burning pollution problem, increasing peasant income, growth of agricultural efficiency are realized.The covering machine can also be used for farmland, desert, the sand outside orchard
Beach, barren soil soil improvement, culture fertility.
The content of the invention
The purpose of this utility model:A kind of crawler type orchard straw covering machine is disclosed, can realize orchard improving straw mulching with
