Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and the specific embodiments given in the accompanying drawings.

[0016] Such as figure 1 Shown, a kind of soil wind erosion measurement device, in the structure, its support leg of rectangular support 1 is high 20~30cm, is provided with track 10 on two long sides parallel to rectangular support 1, and this track 10 is rack, is erected on track The longitudinal section is the air guide tube 11 in the shape of a "trumpet". The small opening of the air guide tube is the air outlet, that is, the air outlet. Axial flow fan 12, the drive shaft on both sides of the air guide tube is equipped with a driving gear 5 and a driven gear 7 that cooperate with the rack on the bracket 1, the drive shaft 4 at the rear end of the air guide tube is a driving shaft, and a rocker is installed on the driving shaft. The handle 6, the driving gear 4 and the rocker 6 are fixed to the driving s...

Abstract

The invention discloses a soil wind erosion measuring device. Tracks are arranged on two long edges of a rectangular support; a ventilating duct of which the longitudinal section is in a shape of a 'horn' is erected on the tracks; a ventage of the ventilating duct is an air outlet, and the air outlet is downwards and forms an included angle of between 10 and 30 degrees with the ground; axial flow fans are arranged in the ventilating duct side by side; idler wheels matched with the support tracks are arranged on both sides of the ventilating duct; a rocking handle is arranged on a driving shaft; the rocking handle is shaken, so that the ventilating duct makes parallel movement forwards along the support tracks; a sand table is arranged in the front of the ventilating duct below the support; a wind erosion object receiver is arranged in the front of the sand table; and when the ventilating duct moves forwards, strong air currents blown from the air outlet of the ventilating duct blow wind erosion objects such as sand and dust in the sand table to move forwards, so that the wind erosion objects falls into the wind erosion object receiver. The device can simulate the wind-blown sand movement of different underlying surfaces indoors, and can measure the wind-erosion amount and sand detention amount under the conditions of different underlying surfaces through on-site operation in the open air. The soil wind erosion measuring device has the advantages of simple structure, small volume and convenient operation and carrying.

Description

technical field [0001] The invention relates to a device for environmental ecology research, in particular to a soil wind erosion measuring device. Background technique [0002] Sand and dust from the land have a very negative impact on transportation and people's lives in downwind areas, and at the same time lead to soil and water loss in farmland in sand and dust source areas, decreased soil productivity, and aggravated desertification. Studying the causes and movement principles of sand and dust, the influence of different underlying surfaces on wind speed, wind erosion, and sediment retention, etc., will help reveal the succession of the ecological environment and soil fertility changes in the dust source area, the establishment of farmland protective belts and soil conservation tillage. , as well as traffic route design and urban environmental planning are of great significance. Soil dust movement is affected by many factors such as atmospheric circulation, geological ...
