Abstract
The invention discloses a shovel wall structure of a convex arc ridging shovel. A plurality of arc-shaped convex strips which are arranged in a parallel mode are formed on the surface of the convex arc ridging shovel; the width of every arc-shaped convex strip is 9 to 12 mm; the height of every arc-shaped convex strip is 5 to 9 mm; a groove is formed between every two adjacent arc-shaped convex strips; the width of every groove is 2 mm; the bilateral sides of the convex arc ridging shovel are inclined planes; and an included angle between each of the two inclined planes and the bottom surface of every groove is 25 degrees. Compared with the existing ridging shovel model, the shovel wall structure of the convex arc ridging shovel can reduce ridging resistance, increase the ridging speed and reduce fuel consumption.
Description
Technical field
The present invention relates to a kind of ridging shovel, particularly a kind of dome arc ridging shovel shovel wall construction.
Background technology
Existing ridging shovel is in the process of ridging, and resistance ratios is bigger, causes ridging speed slow and increased the consumption of fuel.If can reduce the resistance of ridging, just can accelerate the speed of ridging and the consumption of minimizing fuel.
Summary of the invention
The objective of the invention is to solve existing ridging shovel in the process of ridging, resistance ratios is bigger, cause the big problem of consumption of the slow and fuel of ridging speed, and the consumption of resistance, the speed of accelerating ridging and minimizing fuel that a kind of dome arc ridging shovel shovel wall construction, the present invention can reduce ridging is provided.
The present invention is formed with a plurality of arc raised lines that are arranged in parallel on the surface of ridging shovel, the width of arc raised line is 9 ~ 12mm, the height of arc raised line is 5 ~ 9mm, be formed with groove between adjacent two arc raised lines, the width of groove is 2mm, the two sides of ridging shovel are the inclined-plane, and the angle between this inclined-plane and the trench bottom surfaces is 25 °.
Beneficial effect of the present invention: compare with existing ridging shovel prototype, the present invention can reduce the consumption of the resistance of ridging, the speed of accelerating ridging and minimizing fuel.

Fig. 1 is front view of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the upward view of Fig. 1.
Fig. 4 is that A-A among Fig. 1 is to cutaway view.
Embodiment
See also Fig. 1, Fig. 2 and shown in Figure 3, present embodiment is to be formed with a plurality of arc raised lines 2 that are arranged in parallel on the surface of ridging shovel 1, the width B of arc raised line 2 is 9 ~ 12mm, the height C of arc raised line 2 is 5 ~ 9mm, be formed with groove 3 between adjacent two arc raised lines 2, the width D of groove 3 is 2mm, and the two sides of ridging shovel 1 are inclined-plane 4, angle between this inclined-plane 4 and groove 3 bottom surfaces is 25 °, as shown in Figure 4.
The contrast experiment
Choosing dome arcuate furrow ridging shovel and ridging shovel prototype carries out indoor soil box and tests.At two kinds of different soil moisture contents 18.61%, 20.9%, at three kinds of ridging speed 0.68 m/s, 0.87 m/s experimentizes under the condition of 1.11 m/s respectively.
Two types ridging shovel is tested respectively three times under different ridging speed, and gather the ridging drag data in real time by BLR-1 type sensor, the stable section averaged of data intercept, the calibration curve of substitution sensor obtains the ridging resistance of ridging shovel under certain ridging speed of this type again.
1. the moisture content of soil is 18.61% o'clock, and ridging speed is under the 0.68 m/s condition, and the ridging resistance of ridging shovel prototype is 126.4N, and the ridging resistance of dome arcuate furrow ridging shovel is 124.2N; Same moisture content, ridging speed are under the 0.87 m/s condition, and the ridging resistance of ridging shovel prototype is 147.4N, and the ridging resistance of dome arcuate furrow ridging shovel is 144.2N; Same moisture content, ridging speed are under the 1.11 m/s conditions, and the ridging resistance of ridging shovel prototype is 174.9N, and the ridging resistance of dome arcuate furrow ridging shovel is 171.4N.
2. the moisture content of soil is 20.9% o'clock, and ridging speed is under the 0.68 m/s condition, and the ridging resistance of ridging shovel prototype is 134.3N, and the ridging resistance of dome arcuate furrow ridging shovel is 132.4N; Same moisture content is under the 0.87 m/s condition in ridging speed, and the ridging resistance of ridging shovel prototype is 155.4N, and the ridging resistance of dome arcuate furrow ridging shovel is 151.8N; Same moisture content is under the 1.11 m/s conditions in ridging speed, and the ridging resistance of ridging shovel prototype is 185.1N, and the ridging resistance of dome arcuate furrow ridging shovel is 182.2N.Under the same moisture content situation, the average resistance-reducing yield of dome arcuate furrow ridging shovel is 1.85%, and more significant resistance reducing effect is arranged.
Table 1 is the ridging resistance of 18.61% o'clock ridging shovel under three kinds of ridging speed for moisture content
Table 2 moisture content is the ridging resistance of 20.9% o'clock ridging shovel under three kinds of ridging speed
