Description

Technical Field

[0001] The present invention relates to the field of soil and water loss control, and more specifically, to a device and method for controlling soil and water loss in the geomorphology of a small watershed. Background Art

[0002] A small watershed generally refers to a relatively independent and enclosed natural water-collecting area with a catchment area of less than 50 square kilometers bounded by a watershed and the downstream river outlet section below the second- and third-level tributaries. In hydraulics, it usually refers to a watershed with an area of less than 50 square kilometers or a river course basically within the scope of a county. Soil and water loss control is an important part of small watershed management. For hilly geomorphology, by building platforms to prevent soil and water loss and carrying out forestry or agricultural planting, soil and water can be protected and farmers' income can be increased.

[0003] Currently, when building platforms to prevent soil and water loss, an excavator or the like is used to first dig out the prototype of the platform to prevent soil and water loss, and then it is leveled manually, which consumes a lot of manpower. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a device and method for controlling soil and water loss in the geomorphology of a small watershed, which is convenient for controlling soil and water loss in the geomorphology of a small watershed.

[0005] The present invention adopts the following technical solutions to achieve the invention purpose:

[0007] As a further limitation of this technical solution, the symmetric second vertical rods are respectively fixedly connected to square plates, and the square plates are fixedly connected to symmetric cylinders.

[0008] As a further limitation of this technical solution, the bracket is rotatably connected to symmetric first vertical plates, one ends of symmetric first springs are respectively fixedly connected to the corresponding first vertical plates, the other ends of the symmetric first springs are respectively fixedly connected to the corresponding brackets, and the symmetric cylinders respectively contact the corresponding first vertical plates.

[0009] As a further limitation of this technical solution, the first vertical rod is rotatably connected to a baffle.

[0010] As a further limitation of this technical solution, the inclined surface of the support block is fixedly connected to a T-shaped plate, and the T-shaped plate is fixedly connected to a mounting plate.

[0011] A soil and water loss control method for small watershed landforms, characterized by including the following steps:

[0012] Step 1: Install the mounting plate on a moving mechanism, and the moving mechanism drives the device to move in the front-rear direction and turn.

[0013] Step 2: Operate the moving mechanism to achieve the slow forward movement of the device. Meanwhile, control the electric push rod to reciprocate telescopically.

[0014] Step 3: The lower scraper swings reciprocally to scrape the soil that is relatively lower and outer.

[0015] Step 4: The upper scraper swings reciprocally to scrape the soil that is relatively upper and inner. The swinging amplitude of the upper scraper is greater than that of the lower scraper, and there is a certain overlap between their swinging areas to avoid missing soil.

[0016] Step 5: The soil scraped off by the lower scraper and the upper scraper falls onto the square plate. When the soil moves backward relative to the baffle, the soil drives the baffle to swing, and the soil smoothly enters the area formed by the baffle and the first vertical plate. When the soil moves forward relative to the baffle, the baffle presses against the first vertical rod to keep it vertical, and the baffle obstructs the forward movement of the soil.

[0017] Step 6: The first vertical plate swings reciprocally. When the first vertical plate swings outward, it drives the soil on the square plate to fall onto the horizontal plane of the platform for preventing soil erosion.

[0018] Step 7: The third vertical plate swings reciprocally and simultaneously moves forward with the moving mechanism to contact the vertical surface of the platform for preventing soil erosion, and swings reciprocally to contact the vertical surface of the platform for preventing soil erosion to trim the vertical surface of the platform for preventing soil erosion.

[0019] Step 8: After trimming the corresponding section of the platform for preventing soil erosion of the device, operate the moving mechanism to make the device corresponding to the next section of the platform for preventing soil erosion.

[0020] As a further limitation of this technical solution, when the electric push rod reciprocates telescopically, the electric push rod drives the second vertical rod, the arc rod, the guide block, the square plate and the cylinder to move reciprocally. Under the action of the first spring, the cylinder drives the first vertical plate to swing reciprocally, the guide block drives the third vertical rod to move reciprocally, the third vertical rod drives the linear slider to move reciprocally along the linear track, the linear slider drives the second spring to move reciprocally, the linear slider drives the third vertical rod to move reciprocally along the guide block, the third vertical rod drives the connecting block, the third vertical plate, the short rod, the long rod, the lower scraper and the reciprocating swing, the third square block drives the round rod to swing reciprocally in the straight groove, the round rod drives the square rod to swing reciprocally, and the square rod drives the upper scraper to swing reciprocally.

[0021] As a further limitation of this technical solution, the second spring always remains in a stretched state to assist the linear slider to move upward along the linear track.

[0022] As a further limitation of the present technical solution, the lower ends of the upper scraping plate and the lower scraping plate are sharp at the contact with the soil.

[0023] As a further limitation of the present technical solution, the lower scraping plate is inclined.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] 1. By limiting the round rod in the straight groove, the present device enables the swinging amplitude of the upper scraping plate to be greater than that of the lower scraping plate. The lower scraping plate reciprocally swings to scrape the relatively lower and outer soil. The upper scraping plate reciprocally swings to scrape the relatively upper and inner soil, which conforms to the landform shape of the hilly area, and there is a certain overlap between the swinging areas of the two, avoiding missing soil. By rotatably connecting the baffle to the first vertical rod and limiting the baffle with the first vertical rod, when the soil moves backward relative to the baffle, the soil drives the baffle to swing, and the soil smoothly enters the area formed by the baffle and the first vertical plate. When the soil moves forward relative to the baffle, the baffle hinders the progress of the soil. By using the first spring, under the action of the cylinder, the first vertical plate reciprocally swings. When the first vertical plate swings outward, it drives the soil on the square plate to fall onto the horizontal plane of the platform for preventing soil erosion. The square plate reciprocally moves back and forth to level the area excavated by the upper scraping plate and the lower scraping plate, realizing the preliminary leveling of the horizontal plane of the platform for preventing soil erosion. The third vertical plate reciprocally swings and simultaneously moves forward along with the moving mechanism to contact the vertical surface of the platform for preventing soil erosion, and reciprocally swings to contact the vertical surface of the platform for preventing soil erosion to trim the vertical surface of the platform for preventing soil erosion.

[0026] 2. Through the ingenious design, the present device realizes the construction of the platform for preventing soil erosion on the uphill of the hilly area, realizes the excavation of the platform for preventing soil erosion, the leveling of the horizontal plane and the vertical plane, and spreads the soil generated from excavating the platform for preventing soil erosion onto the horizontal plane of the platform for preventing soil erosion, saving manpower and improving efficiency.

[0043] A method for controlling soil and water loss in a small watershed landform includes the following steps:

[0044] Step 1: Install the mounting plate 1 onto the moving mechanism, and the moving mechanism drives the device to move in the front-back direction and turn;

[0045] Step 2: Operate the moving mechanism to make the device move slowly forward. At the same time, control the electric push rod 16 to reciprocate telescopically;

[0046] Step 3: The lower scraper 23 swings reciprocally to scrape the soil that is relatively lower and outer;

[0047] Step 4: The upper scraper 4 swings reciprocally to scrape the soil that is relatively upper and inner. The swing amplitude of the upper scraper 4 is greater than that of the lower scraper 23, and there is a certain overlap in their swing areas to avoid missing soil;

[0048] Step 5: The soil scraped off by the lower scraper 23 and the upper scraper 4 falls onto the square plate 8. The square plate 8 drives the soil to move reciprocally. When the soil moves backward relative to the baffle 6, the soil drives the baffle 6 to swing, and the soil smoothly enters the area formed by the baffle 6 and the first vertical plate 7. When the soil moves forward relative to the baffle 6, the baffle 6 presses against the first vertical rod 5 to keep vertical, and the baffle 6 hinders the forward movement of the soil;

[0049] Step 6: The first vertical plate 7 swings reciprocally. When the first vertical plate 7 swings outward, it drives the soil on the square plate 8 to fall onto the horizontal plane of the platform for preventing soil erosion;

[0050] Step 7: The third vertical plate 26 swings reciprocally and moves forward following the moving mechanism to contact the vertical surface of the platform for preventing soil erosion, and swings reciprocally to contact and trim the vertical surface of the platform for preventing soil erosion;

[0051] Step 8: After trimming the corresponding section of the platform for preventing soil erosion of the device, operate the moving mechanism to make the device corresponding to the next section of the platform for preventing soil erosion.

[0052] When the electric push rod 16 reciprocates telescopically, the electric push rod 16 drives the second vertical rod 22, the arc-shaped rod 21, the guide block 20, the square plate 8 and the cylinder 19 to move reciprocally. Under the action of the first spring 17, the cylinder 19 drives the first vertical plate 7 to swing reciprocally. The guide block 20 drives the third vertical rod 28 to move reciprocally. The third vertical rod 28 drives the linear slider 29 to move reciprocally along the linear track 9. The linear slider 29 drives the second spring 18 to move reciprocally. The linear slider 29 drives the third vertical rod 28 to move reciprocally along the guide block 20. The third vertical rod 28 drives the connecting block 27, the third vertical plate 26, the short rod 25, the long rod 24, the lower scraper 23 and the reciprocating swing. The third square block 33 drives the round rod 32 to swing reciprocally in the straight groove 31. The round rod 32 drives the square rod 30 to swing reciprocally. The square rod 30 drives the upper scraper 4 to swing reciprocally.

[0053] The second spring 18 always remains in a stretched state to assist the linear slider 29 to move upward along the linear track 9.

[0054] The lower ends of the upper scraper 4 and the lower scraper 23 are sharp at the contact with the soil.

[0055] The lower scraper 23 is inclined.

[0056] The working process of the present invention is as follows: The mounting plate 1 is installed on the moving mechanism, and the moving mechanism drives the device to move forward and turn in the front-rear direction.

[0057] Operate the moving mechanism to make the device move slowly forward. At the same time, control the electric push rod 16 to reciprocate telescopically. The electric push rod 16 drives the second vertical rod 22, the arc-shaped rod 21, the guide block 20, the square plate 8 and the cylinder 19 to move reciprocally. Under the action of the first spring 17, the cylinder 19 drives the first vertical plate 7 to swing reciprocally. The guide block 20 drives the third vertical rod 28 to move reciprocally. The third vertical rod 28 drives the linear slider 29 to move reciprocally along the linear track 9. The linear slider 29 drives the second spring 18 to move reciprocally. The linear slider 29 drives the third vertical rod 28 to move reciprocally along the guide block 20. The third vertical rod 28 drives the connecting block 27, the third vertical plate 26, the short rod 25, the long rod 24, the lower scraper 23 and the reciprocating swing. The third square block 33 drives the round rod 32 to swing reciprocally in the straight groove 31. The round rod 32 drives the square rod 30 to swing reciprocally. The square rod 30 drives the upper scraper 4 to swing reciprocally.

[0058] The lower scraper 23 reciprocally swings to scrape the soil that is relatively lower and outer. The upper scraper 4 reciprocally swings to scrape the soil that is relatively upper and inner. The swinging amplitude of the upper scraper 4 is greater than that of the lower scraper 23, and there is a certain overlap in their swinging areas to avoid missing soil. The soil scraped off by the lower scraper 23 and the upper scraper 4 falls onto the square plate 8. The square plate 8 drives the soil to reciprocally move. When the soil moves backward relative to the baffle 6, the soil drives the baffle 6 to swing, and the soil smoothly enters the area formed by the baffle 6 and the first vertical plate 7. When the soil moves forward relative to the baffle 6, the baffle 6 is kept vertical by closely adhering to the first vertical rod 5, and the baffle 6 hinders the forward movement of the soil. The first vertical plate 7 reciprocally swings. When the first vertical plate 7 swings outward, it drives the soil on the square plate 8 to fall onto the horizontal plane of the platform for preventing soil erosion. The third vertical plate 26 reciprocally swings and simultaneously moves forward along with the moving mechanism to contact the vertical surface of the platform for preventing soil erosion, and reciprocally swings to contact and trim the vertical surface of the platform for preventing soil erosion.

[0059] After trimming the platform for preventing soil erosion corresponding to this section of the device, operate the moving mechanism to make the device correspond to the next section of the platform for preventing soil erosion.

[0060] This device realizes that the swinging amplitude of the upper scraper 4 is greater than that of the lower scraper 23 by limiting the round rod 32 into the straight groove 31. The lower scraper 23 reciprocally swings to scrape the soil that is relatively lower and outer. The upper scraper 4 reciprocally swings to scrape the soil that is relatively upper and inner, which conforms to the landform shape of the hilly area, and there is a certain overlap in their swinging areas to avoid missing soil; by adopting the baffle 6 rotatably connected to the first vertical rod 5 and the first vertical rod 5 limiting the baffle 6, when the soil moves backward relative to the baffle 6, the soil drives the baffle 6 to swing, and the soil smoothly enters the area formed by the baffle 6 and the first vertical plate 7. When the soil moves forward relative to the baffle 6, the baffle 6 hinders the forward movement of the soil; by adopting the first spring 17, under the action of the cylinder 19, the first vertical plate 7 reciprocally swings. When the first vertical plate 7 swings outward, it drives the soil on the square plate 8 to fall onto the horizontal plane of the platform for preventing soil erosion; the square plate 8 reciprocally moves back and forth to level the area excavated by the upper scraper 4 and the lower scraper 23, realizing the preliminary leveling of the horizontal plane of the platform for preventing soil erosion. The third vertical plate 26 reciprocally swings and simultaneously moves forward along with the moving mechanism to contact the vertical surface of the platform for preventing soil erosion, and reciprocally swings to contact and trim the vertical surface of the platform for preventing soil erosion.

[0061] Through the ingenious design of this device, it realizes building the platform for preventing soil erosion on the uphill of the hilly area, realizes the excavation of the platform for preventing soil erosion, the leveling of the horizontal plane and the vertical plane, and spreads the soil generated by excavating the platform for preventing soil erosion onto the horizontal plane of the platform for preventing soil erosion, saving manpower and improving efficiency.
