Technical field
The utility model relates to and improves the farming tool technique, and it is bigger to be specially adapted to the gradient, and soil is mainly reduced from domatic direct loss, laborsaving and reduce the cost of making hoe in hills area, mountain area that length of grade is short.
Background technology
The soil erosion of ploughing in the slope not only causes river, reservoir sedimentation, is one of river, the main sediment source of reservoir, and more seriously the big scale soil of the annual forfeiture in arable land, slope causes the soil structure variation, the quality chap, and fertility is degenerated and the agriculture underproduction.This is owing to except water erosion, also have very serious tillage erosion.In hills area and mountain area farming instrument mainly is hoe, and tillage method is mainly straight plowing and does, the peasant when farming because the acting in conjunction of drop-down active force and domatic gravity makes soil to downslope motion.Studies show that, the gradient be 4%～43% domatic in, the soil displacement to direction of fall of adopting the farming of hoe single to cause reaches 36～113kg/m, the erosion rate of single farming is 24～75t/hm
2Serious tillage erosion produces very adverse influence to soil and crop yield: the soil thickness at sloping top since year after year farming have only about 30% of slope bottom, the crop yield at top, slope only be slope bottom 50% or still less, the Ipomoea batatas of one of its Zhongshan District, hills area chief crop is the highest can only to reach 50%, is lower than 20% at least.
The utility model content
The purpose of this utility model provides a kind of hoe that prevents tillage erosion, with by improving the farming instrument of hills area, hill farmer, reduces the cost of sloping arable soil loss, labor savings and minimizing tools.
This novel purpose is realized by following design: a kind of hoe that prevents tillage erosion, comprise the hoe body, the cutting edge portion position of hoe body has a rectangular-shaped cutting edge portion window, last cutting edge is arranged at the top of cutting edge portion window, and is positioned on the hoe body of cutting edge portion window top and also has a rectangular body portion window that is used to spill soil block.
The width of the rectangular body portion window on the above-mentioned hoe body and area are all greater than the width and the area of cutting edge portion window.
This novel farming instrument has carried out following improvement to conventional tillage instrument (hoe):
1, opened a cutting edge portion window in cutting edge portion, the benefit of such design has 3 points:
A, such design have reduced the contact area of the hoe and the soil body, can reduce the soil erosion of ploughing in the slope.Not only loosen the soil in the farming on ploughing in the slope in hills area, hill farmer, and because hoe is from going up a slope to direction of fall along the slope motion during farming, soil moves downward thereupon.The peasant must adopt such tillage method for farming is convenient, laborsaving.And open a window in cutting edge portion, and having reduced the contact area of soil and farming instrument like this, the soil that pulls down has also just reduced, and the soil loss amount of ploughing in the slope is also with regard to corresponding minimizing;
B, reduced the contact area of the hoe and the soil body, be convenient to the farming instrument and be inserted into the soil body, can play the labour-saving purpose at cutting edge portion windowing;
C, reduced the steel usage amount of making hoe, reached the purpose of saving cost at cutting edge portion windowing.
2, the effect that is inserted into the soil body is played by cutting edge portion when farming, and the effect of this point and traditional hoe is identical, but since the area of the cutting edge portion contact soil body reduce, so can reach the labour-saving effect.
3, the last cutting edge at cutting edge portion window top also can play the effect that is inserted into the soil body, but owing to opened window in its underpart, loosens the soil and can not carry the effect of soil to the descending displacement so can play.Last cutting edge herein is equivalent to 3 spuds with original cutting edge simultaneously, and the complete cutting edge that is inserted into the soil body and loosening function and traditional hoe that is played is consistent.
4, open a bigger body window again on the main body section top of hoe, this window can play following 3 effects:
When a, peasant's farming soil block from then on window directly spill, remain on original position, promptly kept the soil in sloping arable land, reduced the loss of sloping arable soil, reached simultaneously the effect of loosening the soil again;
B, opened a bigger window at this position and can save a large amount of steel,, made certain contribution for nation-building conservation-minded society simultaneously for the peasant has saved cost;
C, open the weight that a bigger window has alleviated hoe at this position, reach the labour-saving effect, from then on window spills a large amount of soil blocks simultaneously, has also reached the labour-saving effect.
At the uppermost window of hoe (position 5) is to uproot handle for installing, and this position is identical with traditional hoe.
Description of drawings
Fig. 1 is the schematic perspective view of this farming instrument hoe;
Hoe shown in Fig. 2 Fig. 1 is set up the stereogram behind the hoe handle.
Embodiment
As shown in Figure 1, this novel hoe body 1 that comprises, the cutting edge portion position of hoe body 1 has the window 1b of cutting edge portion of a rectangular shape, last cutting edge 1c is arranged at the top of the window 1b of cutting edge portion, and is positioned on the hoe body 1 of the window 1b of cutting edge portion top and also has a window 1d of rectangular body portion that is used to spill soil block.The specification of this hoe (hoe is installed 2 by the uppermost window 1a of hoe body place among Fig. 2) is: main body section is about 20cm * 12cm * 0.5cm, little with traditional hoe difference, yet, compare with traditional hoe, this farming instrument has increased by two windows, promptly two windows (window 1b of cutting edge portion and main part window 1d) have been opened in cutting edge portion and main body section, She Ji purpose is exactly can reach to reduce the result that sloping arable soil runs off like this, can play effect laborsaving and the saving rolled steel dosage simultaneously.
