[0004] Therefore, this utility model provides an acidic soil improvement device for agricultural planting. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problem that in existing technologies, when improving acidic soil, the amendment is generally sprayed on the soil surface, but under the influence of high temperature weather or hard soil, it is difficult for the amendment to penetrate into the soil, which greatly affects the improvement effect, this utility model proposes an acidic soil improvement device for agricultural planting.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An acidic soil improvement device for agricultural planting, comprising a U-shaped frame; a set of connecting rods is provided at the bottom of the U-shaped frame, and a plow blade is fixedly connected to the bottom of the connecting rods; the top view of the plow blade is an isosceles triangle, and the two sides of the plow blade are arc-shaped; a first groove is formed at the bottom of the plow blade; a nozzle is installed in the first groove; a flexible hose is provided on the nozzle; a liquid tank is fixedly connected to the side wall of the U-shaped frame; a cover plate is bolted to the top of the liquid tank; a feed pipe is fixedly connected to the top of the cover plate; a discharge pipe is formed on the side wall of the liquid tank; valves are provided on both the discharge pipe and the feed pipe; the flexible hose and the liquid tank are interconnected, and a feeding assembly is provided inside the liquid tank.

[0007] Preferably, the feeding assembly includes a square cylinder; a square cylinder is fixedly connected to the bottom end of the liquid tank; a first through groove is formed on the side wall of the square cylinder; a set of first through holes is formed at the bottom end of the liquid tank; the bottom end of the square cylinder is connected to a hose through the first through holes; a sealing plate is slidably connected to the inner wall of the square cylinder; the sealing plate slides up and down through a power unit.

[0008] Preferably, the power unit includes a first rotating shaft; a second through groove is provided on the side wall of the square cylinder; a sliding plate is slidably connected between the two side walls of the liquid tank; a first sliding groove is provided on the side wall of the sliding plate; an inverted L-shaped column is fixedly connected to the sealing plate, and the horizontal column of the inverted L-shaped column is fixedly connected to the sliding plate through the second through groove; a pair of symmetrically distributed first rotating shafts are rotatably connected to the inner wall of the liquid tank; the first rotating shafts are driven by a synchronous pulley and a synchronous belt; a disc is fixedly connected to the end of the first rotating shaft; a pin is rotatably connected to the disc; the pin is slidably connected in the first sliding groove; the first rotating shaft is rotated by a motor.

[0009] Preferably, a set of second grooves is provided at the bottom of the liquid tank; the cross-sectional view of the second groove is an inverted isosceles trapezoid; the square cylinder is fixed to the bottom of the second groove, and the first through hole is opened on the bottom of the second groove; the set of second grooves are interconnected through a through groove; the discharge pipe and the second groove are interconnected.

[0010] Preferably, the first through groove is lower than the opening surface of the second groove; the bottom end of the second through groove is higher than the opening surface of the second groove.

[0011] Preferably, the top of one set of connecting rods passes through the U-shaped frame and is fixedly connected to a lifting plate; a set of threaded grooves are provided on the connecting rods; a set of threaded posts are threadedly connected to the U-shaped frame; the connecting rods are fixed by the threaded posts and threaded grooves.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The acidic soil improvement device for agricultural planting described in this utility model has a nozzle set on the first groove of the plow blade. Because the top view of the plow blade is an isosceles triangle and the two sides of the plow blade are arc-shaped, the nozzle can spray an amendment while turning the soil. At the same time, after the plow blade divides the soil, some soil will return to the center of the plow, thus covering the amendment sprayed in the center of the plow. This not only effectively avoids the influence of high temperature weather, but also allows the amendment to be directly inside the soil, while loosening the soil, greatly improving the improvement effect on acidic soil.

[0014] 2. The acidic soil amendment device for agricultural planting described in this utility model, when the plow blade is plowing the soil, the motor works and drives a pair of first rotating shafts to rotate. The rotation of the first rotating shafts causes the disc to rotate, which in turn drives the pin to rotate. Since the pin slides in the first sliding groove, it drives the slide plate to move up and down. The up and down movement of the slide plate drives the sealing plate to move up and down through the inverted L-shaped column. When the sealing plate moves down, when the sealing plate is below the first through groove, the sealing plate will spray the amendment liquid through the hose and nozzle. When the sealing plate moves up above the first through groove, the liquid in the tank will enter the square cylinder through the first through groove. The motor is a reducer, and the spraying on the soil is intermittent, which does not affect the soil amendment effect. The amendment is allowed to penetrate the soil and then spread to the surrounding areas, which can still ensure the overall soil amendment. Attached Figure Description

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown, the present invention discloses an acidic soil improvement device for agricultural planting, comprising a U-shaped frame 1; a set of connecting rods 11 are provided at the bottom end of the U-shaped frame 1, and a plow blade 12 is fixedly connected to the bottom end of the connecting rods 11; the top view cross-section of the plow blade 12 is an isosceles triangle, and the two sides of the plow blade 12 are arc-shaped; a first groove 13 is formed at the bottom end of the plow blade 12; a nozzle 14 is installed in the first groove 13; a hose 15 is provided on the nozzle 14; a liquid tank 16 is fixedly connected to the side wall of the U-shaped frame 1; a cover plate 17 is bolted to the top of the liquid tank 16; an inlet pipe 18 is fixedly connected to the top of the cover plate 17; an outlet pipe 19 is formed on the side wall of the liquid tank 16; valves are provided on both the outlet pipe 19 and the inlet pipe 18; the hose 15 and the liquid tank 16 are interconnected, and the liquid tank 16 contains... The invention includes a feeding component. In existing technologies, when improving acidic soil, the amendment is typically sprayed onto the soil surface. However, under conditions of high temperatures or hard soil, the amendment is difficult to penetrate the soil, significantly affecting the improvement effect. Therefore, this invention places the nozzle 14 on the first groove 13 of the plow blade 12 during operation. Since the top view of the plow blade 12 is an isosceles triangle, and the two sides of the plow blade 12 are curved, the nozzle 14 sprays the amendment while turning the soil. Simultaneously, after being divided by the plow blade 12, some soil returns to the center of the plow, covering the amendment sprayed there. This effectively avoids the effects of high temperatures and allows the amendment to be directly embedded in the soil, while also loosening the soil, greatly improving the improvement effect on acidic soil.

[0024] The feeding assembly includes a square cylinder 2; the square cylinder 2 is fixedly connected to the bottom end of the liquid tank 16; a first through groove 22 is opened on the side wall of the square cylinder 2; a set of first through holes 23 are opened at the bottom end of the liquid tank 16; the bottom end of the square cylinder 2 is interconnected with the hose 15 through the first through holes 23; a sealing plate 21 is slidably connected to the inner wall of the square cylinder 2; the sealing plate 21 slides up and down through a power unit;

[0025] The power unit includes a first rotating shaft 24; a second through groove 29 is provided on the side wall of the square cylinder 2; a sliding plate 27 is slidably connected between the two side walls of the liquid tank 16; a first sliding groove 28 is provided on the side wall of the sliding plate 27; an inverted L-shaped column 291 is fixedly connected to the sealing plate 21, and the horizontal column of the inverted L-shaped column 291 is fixedly connected to the sliding plate 27 through the second through groove 29; a pair of symmetrically distributed first rotating shafts 24 are rotatably connected to the inner wall of the liquid tank 16; the first rotating shafts 24 are driven by a synchronous pulley and a synchronous belt; a disc 25 is fixedly connected to the end of the first rotating shaft 24; a pin 26 is rotatably connected to the disc 25; the pin 26 is slidably connected in the first sliding groove 28; the first rotating shafts 24 are rotated by a motor.

[0026] During operation, when the plow blade 12 is plowing the soil, the motor is working and will drive a pair of first rotating shafts 24 to rotate. The rotation of the first rotating shafts 24 will cause the disc 25 to rotate, which in turn will drive the pin 26 to rotate. Since the pin 26 slides in the first sliding groove 28, it will drive the slide plate 27 to move up and down. The up and down movement of the slide plate 27 will drive the sealing plate 21 to move up and down through the inverted L-shaped column 291. When the sealing plate 21 moves down, when the sealing plate 21 is below the first through groove 22, the sealing plate 21 will spray the soil conditioner liquid through the hose 15 and the nozzle 14. When the sealing plate 21 moves up and is higher than the first through groove 22, the liquid in the container will enter the square cylinder 2 through the first through groove 22. The motor is a reducer, and the spraying of the soil is intermittent, which does not affect the soil improvement effect. The conditioner is allowed to penetrate the soil and then spread to the surrounding areas, which can still ensure the overall soil improvement.

[0027] The liquid tank 16 has a set of second grooves 3 at its bottom end; the cross-section of the second groove 3 is an inverted isosceles trapezoid; the square cylinder 2 is fixed to the bottom of the second groove 3, and the first through hole 23 is opened on the bottom of the second groove 3; the set of second grooves 3 are interconnected through the through groove 31; the discharge pipe 19 is interconnected with the second groove 3.

[0028] The first through groove 22 is lower than the opening surface of the second groove 3; the bottom of the second through groove 29 is higher than the opening surface of the second groove 3. During operation, the first barrel is lower than the opening surface of the second groove 3, which can ensure that the liquid in the liquid tank 16 can be fully utilized. At the same time, after use, the liquid in the liquid tank 16 can be drained through the discharge pipe 19. The liquid in the hose 15 and the nozzle 14 is in small quantity. After the liquid in the liquid tank 16 is drained, the up and down movement of the sealing plate 21 can spray the liquid in the hose 15 and the nozzle 14 completely, avoiding residue.

[0029] A set of connecting rods 11 passes through the top of the U-shaped frame 1 and is fixedly connected to a lifting plate 32; a set of threaded grooves 33 are provided on the connecting rods 11; a set of threaded posts 34 are threadedly connected to the U-shaped frame 1; the connecting rods 11 are fixed by the threaded posts 34 and the threaded grooves 33; during operation, the height of the plow blade 12 can be adjusted by the setting of the lifting plate 32, the threaded posts 34 and the threaded grooves 33, and thus the depth of plowing can be adjusted according to the actual soil conditions.

[0030] Working principle: The nozzle 14 is positioned on the first groove 13 of the plow blade 12. Because the top view of the plow blade 12 is an isosceles triangle, and the two sides of the plow blade 12 are curved, the nozzle 14 sprays soil conditioner while turning the soil. Simultaneously, after being divided by the plow blade 12, some soil returns to the center of the plow, covering the soil conditioner sprayed there. This effectively avoids the effects of high temperatures and allows the soil conditioner to be directly embedded within the soil, while also loosening the soil and greatly improving the improvement effect on acidic soils. While the plow blade 12 is plowing, the motor operates, driving a pair of first rotating shafts 24 to rotate. The rotation of the first rotating shafts 24 causes the disc 25 to rotate. The rotation of disc 25 drives the rotation of pin 26. As pin 26 slides in the first groove 28, it drives slide plate 27 to move up and down. The up and down movement of slide plate 27 drives sealing plate 21 to move up and down through inverted L-shaped column 291. When sealing plate 21 moves down, when it is below the first channel 22, it sprays the soil conditioner liquid through hose 15 and nozzle 14. When sealing plate 21 moves up above the first channel 22, the liquid in the container enters the square cylinder 2 through the first channel 22. The motor is a reducer, and the spraying of soil is intermittent, which does not affect the soil improvement effect. The soil conditioner is allowed to penetrate the soil and then spread to the surrounding area, which can still ensure the overall soil improvement.
