Abstract
The utility model provides a sand and stone separating machine for a gravel-mulched field, and relates to the field of farming equipment. The sand and stone separating machine is pulled by a four-wheel tractor, gravel is shoveled through a digging shovel (1) and is pushed to a conveying belt (4) when the sand and stone separating machine moves mechanically, a power output device of the tractor outputs power to a speed-changing reverser (6), the speed-changing reverser (6) outputs power to a transmission mechanism (10), the transmission mechanism (10) drives the conveying belt (4) to convey the gravel, the rear of the conveying belt (4) is provided with first-level separation comb teeth (8) and second-level separation comb teeth (9), the first-level separation comb teeth (8) can guarantee that big gravel and small gravel are conveyed to the second-level separation comb teeth (9), sand is all leaked off, the second-level separation comb teeth (9) can guarantee that the small gravel within a specified specification range is leaked off, the large gravel falls on the uppermost layer at last, and the sand and the stone of the gravel-mulched field are mechanically separated. The aging problem of the gravel-mulched field is solved and cultivation can be carried out on the gravel-mulched field forever.
Description
Technical field
The utility model relates to a kind of sand separating equipment of agricultural tillage equipment, especially relates to the sand separating equipment of pressing sandy ground.
Background technology
Pressing sandy ground is a kind of a kind of mode of planting plant on hills and Gobi desert that sandstone, cobblestone or flag are layered on.Hills, west area, Gobi desert are more, the use of the haulage vehicles such as modern project car, brought up large-area pressure sandy ground, but press sandy ground will turn in planting process, stone will fall into deep layer, makes it lose daytime heat insulation, prevents moisture evaporation, ask water suction, the effect of retaining and conserveing soil moisture evening, this phenomenon is also referred to as to press the aging of sandy ground.That presses sandy ground utilizes the time limit in 10 to 30 years, and some is even less than 10 years, Gaolan, Gansu spread in short " bitter I, good fortune son, grandson hungry to death ".If do not adopted an effective measure, change the aging phenomenon of pressing sandy ground, cause and press sandy ground can not plant and let a piece of farmland go to waste, not only to grower, cause great loss, and will be an ecocatastrophe, because after the Gobi desert, the hilly ground top layer that within 10000000 year, form covered by sandstone, form drift sand, extremely unstable.
Large-area plantation is also the thing of nearly more than ten years in Ningxia to press sandy ground, press sandy ground aging be also the thing of nearly 2 years, although relevant department's infusion of financial resources is studied, completely also address this problem and need time.For solving the problem of aging of pressing sandy ground, will make stone come back to top layer, for making stone come back to top layer the utility model, designed a kind of simple device, realize sand-stone separator tool.
Summary of the invention
The purpose of this utility model is to overcome prior art complex structure, and fault is many, and power requires high problem, provides a kind of simple in structure, good reliability, and plant equipment easy to maintenance, realizes and presses sandy ground sand-stone separator tool.
The utility model is realized in the following way.
A kind of pressure sandy ground sand-stone separator of agricultural tillage equipment, by digger blade (1), frame (2), sealing strip (3), conveyer belt (4), hitch frame (5), variable-speed reversing apparatus (6), the separated broach (8) of one-level, the second-order separation broach (9) forms, it is characterized in that: the front end in frame (2) is provided with digger blade (1), in digger blade (1) below, be conveyer belt (4), at the upper sand plate (7) of fixedly hugging of conveyer belt (4), variable-speed reversing apparatus (6) outputting power is to transmission mechanism (10), transmission mechanism (10) driving conveying belt (4) is carried sandstone, the separated broach (8) of one-level and the second-order separation broach (9) are installed after conveyer belt (4).
Described digger blade (1) rear end is fixed with sealing strip (3) and prevents that sandstone from spilling between digger blade (1) and conveyer belt (4).
The separated broach (8) of described one-level, the second-order separation broach (9) is by forming along little parallel steel bar under large on several, the gap of steel bar can be adjusted according to actual needs, the gap of separated broach (8) steel bar of one-level is little, guarantee that big or small sandstone is all transported to the second-order separation broach (9), and sand all leaks down, the gap of the second-order separation broach (9) steel bar is slightly large, can guarantee that little sandstone up to specification leaks down, large sandstone is finally fallen the superiors.
The utility model has following effect.
1) sandstone is separated: it comprises separated broach the equipment that the utility model provides, it is characterized in that: on several, under large, along little parallel steel bar, form separated broach, the gap of steel bar can be adjusted according to actual needs, separated broach and ground are certain slope, utilize Action of Gravity Field, sand leaks down, and sandstone slides into the second-order separation broach (9) from the separated broach of one-level (8), little sandstone leaks down, and large sandstone is finally fallen the superiors and realized sandstone separation.
2) simple in structure: the separated broach project organization that the utility model provides is simple, and without movable part, fault is few, without power, be easy to safeguard, having overcome mesh structure needs power and the many disadvantages of fault.
3) prevent that sandstone from flowing backwards: on the conveyer belt in the utility model, fixed by several and hugged sand plate (7), prevented that sandstone from flowing backwards, improved transfer efficiency, in the rear end of digger blade, be fixed with sealing strip (3) and prevent that sandstone from spilling from gap.

The specific embodiment
A pressure sandy ground sand-stone separator for agricultural tillage equipment, adopts four-wheel tractor traction, and digger blade (1) scoops up sandstone, during machine-walking, sandstone is shifted onto on conveyer belt (4); Tractor dynamic power output device outputs power to variable-speed reversing apparatus (6), variable-speed reversing apparatus (6) outputting power is to transmission mechanism (10), transmission mechanism (10) driving conveying belt (4) is carried sandstone, conveyer belt (4) the separated broach (8) of one-level and the second-order separation broach (9) be installed below; The separated broach of one-level (8) guarantees that big or small sandstone is transported to the second-order separation broach (9), and sand all leaks down, the second-order separation broach (9) can guarantee to meet fixing little sandstone and leak down, large sandstone is finally fallen the superiors, realize and press sandy ground sand-stone separator tool, solve the problem of aging of pressing sandy ground, realized continuous the cultivating forever of pressing sandy ground.
