Description

Technical Field

[0001] The present invention relates to the technical field of soil improvement, and particularly to a supporting device for saline-alkali soil improvement. Background Art

[0002] Saline-alkali soil is a type of soil in which the accumulation of salts and alkaline substances in the soil leads to land degradation. It is widely distributed in many regions of the world, especially in arid and semi-arid zones. The existence of saline-alkali soil seriously affects agricultural production, resulting in a decrease or even failure of crop yields and restricting the effective utilization of land resources. Therefore, the improvement and treatment of saline-alkali soil have always been an important topic in the agricultural field.

[0003] Traditional methods for improving saline-alkali soil mainly include physical improvement, chemical improvement, and biological improvement. Physical improvement methods such as deep plowing and soil turning can improve the soil structure, but often require a large amount of manpower and mechanical input, and the effect is limited; chemical improvement methods mainly neutralize the alkaline substances in the soil by adding modifiers (such as gypsum, limestone, etc.), but the uneven application, volatilization, and loss of modifiers are serious, resulting in an unsatisfactory improvement effect; biological improvement methods rely on the planting of salt-tolerant plants and the action of microorganisms, but the effect is slow and it is difficult to meet the needs of large-scale saline-alkali soil treatment.

[0004] Existing saline-alkali soil improvement equipment mostly focuses on a single operation function, such as plowing, soil turning, or modifier application, lacking integrated operation ability. For example, some equipment can only perform soil plowing and crushing, but cannot achieve precise application of modifiers and uniform coverage of the soil; while some other equipment can apply modifiers, but cannot effectively handle the problems of soil plowing and crushing. Such single-function equipment has problems such as low efficiency, high cost, and unsatisfactory improvement effect in practical applications. Summary of the Invention

Detailed Description of the Invention

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0028] The left, right, up, and down positions of each component shown in the drawings are only an arrangement method, and the specific positions are set according to specific needs.

[0029] In one embodiment, as Figures 1-3 shown, a supporting device for saline-alkali soil improvement includes a supporting frame body 100 fixed to the front end of a land preparation vehicle frame, a conditioner storage box 700 provided on the upper side of the supporting frame body 100, and a land preparation mechanism provided on the lower side of the supporting frame body 100. The land preparation mechanism includes a soil guiding walkway 200, a plowing and pulverizing component 300, a feeding component 400, a material spreading component 500, and a dispersing assembly 800. The soil guiding walkway 200 is connected to the lower end of the supporting frame body 100, and the front end of the soil guiding walkway 200 is provided with a shovel plate member 220, and a falling port 210 is opened at the tail of the soil guiding walkway 200. The plowing and pulverizing component 300 is provided at the front end of the soil guiding walkway 200 and above the shovel plate member 220. The plowing and pulverizing component 300 can plow the saline-alkali soil at the front end of the shovel plate member 220 and pulverize the saline-alkali soil on the shovel plate member 220. The feeding component 400 is provided at the middle position of the soil guiding walkway 200 and is connected to the plowing and pulverizing component 300. The feeding component 400 can feed the soil in the soil guiding walkway 200 into it by rotation. When the feeding component 400 is in a rotating state, the feeding component 400 also acts on the plowing and pulverizing component 300 to make it plow and pulverize the soil. The material spreading component 500 is rotatably provided at the bottom of the soil guiding walkway 200, and both ends of the material spreading component 500 are also connected to the conditioner storage box 700. The conditioner in the conditioner storage box 700 enters the inside of the material spreading component 500 from both ends. The material spreading component 500 is used to sprinkle the conditioner inside it on the plowed area by rotation. The dispersing assembly 800 is provided at the tail of the soil guiding walkway 200, and the dispersing assembly 800 can disperse the soil at the tail end of the soil guiding walkway 200 so that it falls on the area where the conditioner is sprinkled.

[0030] In the embodiment of the present invention, the entire device moves along with the land preparation frame. The front end of the entire soil guiding walkway 200 is close to the ground. The feeding component 400 operates and drives the plowing and crushing component 300 to act. The plowing and crushing component 300 plows the saline-alkali land and breaks up the hard plow sole formed by stubble removal. At this time, the falling port 210 shovels part of the plowed saline-alkali soil onto its surface, and the plowing and crushing component 300 crushes the saline-alkali soil on the shovel plate 220; the crushed saline-alkali soil moves along the soil guiding walkway 200 to the tail of the soil guiding walkway 200 under the rotary feeding of the feeding component 400; while the spreading component 500 at the lower end of the soil guiding walkway 200 operates synchronously, the conditioner stored in the conditioner storage box 700 enters the inside of the spreading component 500, and then the spreading component 500 spreads it in a rotating manner in the plowed area; as the entire device moves, the saline-alkali soil at the tail of the soil guiding walkway 200 will fall on the dispersing assembly 800, and the dispersing assembly 800 disperses the saline-alkali soil so that the saline-alkali soil falls and covers the area where the conditioner is spilled. The conditioner effectively enters the deep part of the saline-alkali soil, fully improves the saline-alkali soil, and the soil above the conditioner effectively restricts the volatilization of the conditioner. The plowed saline-alkali land can avoid the loss of the conditioner and improve the effect of saline-alkali soil improvement. Among them, the conditioner is one or a mixture of green manure crops, chemical fertilizers, sandy soil, etc.; the surface of the plowed soil is flat, which promotes the uniform infiltration of water and salt, the balanced desalination of the soil, and improves the effect of rainfall leaching of salt.

[0031] In one embodiment, as Figures 1-4As shown, the feeding component 400 includes a driving box 410 provided at the bottom of the soil guiding aisle 200 and two symmetrically arranged feeding assemblies. The feeding assembly includes a feeding main shaft 420 and a plurality of feeding unit parts 430. The feeding main shaft 420 is rotatably arranged on the soil guiding aisle 200 and the axis of the feeding main shaft 420 is perpendicular to the surface of the soil guiding aisle 200. The bottom of the feeding main shaft 420 is connected to the output end of the driving box 410. The plurality of feeding unit parts 430 are arranged on the feeding main shaft 420 and can feed the saline-alkali soil on the soil guiding aisle 200 to the tail of the soil guiding aisle 200 by means of rotational movement; a transmission member is arranged on one of the feeding main shafts 420 and the transmission member is connected to the plowing and crushing component 300; the transmission member can convert the rotational movement of the feeding main shaft 420 into the power for driving the plowing and crushing component 300 to crush the saline-alkali soil; in the embodiment of the present invention, the driving box 410 works and drives the two feeding main shafts 420 to rotate synchronously, the rotation directions of the two feeding main shafts 420 are opposite, the feeding main shafts 420 drive the feeding unit parts 430 thereon to rotate, the bottom of the rotating feeding unit parts 430 is close to the surface of the soil guiding aisle 200 and feeds the saline-alkali soil on the soil guiding aisle 200 to the tail of the soil guiding aisle 200, and the rotating feeding main shafts 420 also convert their own rotational movement into the power for the plowing and crushing component 300 to crush the saline-alkali soil through the transmission member, so that the saline-alkali soil shoveled out by the shovel plate member 220 is crushed, facilitating the loosening of the soil covering the modifier.

[0032] In one embodiment, as Figures 1-5As shown, a guiding chute 230 is provided on each soil delivery main shaft 420, and one side of the guiding chute 230 is fixedly connected to the side wall of the soil guiding aisle 200. The part of the guiding chute 230 close to the side of the soil guiding aisle 200 is concave in a V shape towards the center. The soil delivery unit part 430 includes a sleeve body 431 sleeved on the soil delivery main shaft 420 and a plurality of first soil delivery plates 432 circumferentially distributed on the outer wall of the sleeve body 431. The first soil delivery plate 432 is hollow, and an upper through opening 434 is formed along its length direction. A second soil delivery plate 433 that can slide is provided inside the first soil delivery plate 432. An upper rod column 435 protruding from the upper through opening 434 is provided at the top of the second soil delivery plate 433, and a ball part 436 is provided at the top of the upper rod column 435. The ball part 436 is connected to a rolling groove provided at the bottom of the guiding chute 230, and the ball part 436 can roll in the rolling groove. In the embodiment of the present invention, when the soil delivery unit part 430 rotates following the soil delivery main shaft 420, the first soil delivery plate 432 and the second soil delivery plate 433 rotate around the center of the soil delivery main shaft 420, and the first soil delivery plate 432 and the second soil delivery plate 433 deliver the saline-alkali soil on the soil guiding aisle 200 to the tail of the soil guiding aisle 200. At the same time, the ball part 436 moves along the guiding chute 230. When the ball part 436 moves to the part of the guiding chute 230 close to the side of the soil guiding aisle 200, the ball part 436 first moves towards the center of the guiding chute 230, and then moves away from the center of the guiding chute 230. The ball part 436 approaches the center of the soil delivery main shaft 420 and drives the second soil delivery plate 433 to retract into the first soil delivery plate 432 through the upper rod column 435, so as to reduce the lengths of the first soil delivery plate 432 and the second soil delivery plate 433. At this time, the first soil delivery plate 432 gradually rotates towards the side of the sleeve body 431 close to the side of the soil guiding aisle 200, and the end of the first soil delivery plate 432 abuts against the side of the soil guiding aisle 200, so as to scrape the saline-alkali soil close to the side of the soil guiding aisle 200 and prevent the saline-alkali soil from being in a position on the soil guiding aisle 200 that is not easy to deliver. When the ball part 436 moves away from the center of the guiding chute 230, the ball part 436 drives the second soil delivery plate 433 to gradually extend from the end of the second soil delivery plate 433, so as to increase the lengths of the first soil delivery plate 432 and the second soil delivery plate 433 and facilitate delivering the saline-alkali soil on the soil guiding aisle 200 from the middle part of the soil guiding aisle 200 to the tail.

The rotary crushing unit can crush the saline-alkali soil shoveled by the shovel plate part 220 through its own rotation. Since the rotary crushing unit is located between the two plowing arms 370, the saline-alkali soil plowed by the plowing teeth 380 is flipped to one side, and the shovel plate part 220 shovels part of the saline-alkali soil onto the soil guide walkway 200, and the rotary crushing unit shovels this part of the saline-alkali soil and crushes it, effectively ensuring that the soil subsequently covered on the improver is loose.

[0034] In one embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the upper end of the front frame 310 is provided with a gear condition 350 along its length direction, the rotary crushing unit includes a crushing rod shaft 320 and a plurality of crushing tool pieces 330, the crushing rod shaft 320 is rotatably arranged on the front frame 310 and the lower end thereof extends to the surface of the earth-guiding walkway 200, the crushing tool piece 330 is arranged on the crushing rod shaft 320 and has a plurality of cutters, the top of the crushing rod shaft 320 has a gear condition 350 meshing with the gear condition 350, the transmission member includes a transmission disk 440 fixed on the top of the feeding main shaft 420 and an eccentric action column 450 arranged on the upper surface of the transmission disk 440, the end surface of the transmission disk 440 also has a bar frame portion 360 and The eccentric action column 450 extends into the interior of the bar frame portion 360, and one end of the bar frame portion 360 is slidably connected to the front frame body 310 and fixedly connected to the gear condition 350; in the embodiment of the present invention, the main shaft 420 rotates and drives the transmission disk 440 to rotate, and the eccentric action column 450 rotates with the transmission disk 440 and drives the bar frame portion 360.

The conveyor belt 620 conveys the saline-alkali soil on its upper surface to the tail of the soil guiding walkway 200, and then it is scattered on the saline-alkali land after being acted on by the dispersing assembly 800. The setting of the retaining bar 630 can increase the friction between the conveyor belt 620 and the saline-alkali soil, and prevent the retaining bar 630 from tilting and causing the saline-alkali soil to stay at one of its ends. At the same time, the retaining bar 630 also acts on the material spreading member 500 to make it rotate, which is convenient for the material spreading member 500 to spread the conditioner.

[0036] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown, the material spreading component 500 includes a material spreading cylinder 530 and two spiral conveying cylinders 510.

The spiral motor 580 operates and drives the spiral conveying member in the spiral conveying cylinder 510. The spiral conveying member rotates to introduce the conditioner into the interior of the material spreading cylinder 530. When each retaining bar 630 passes through the external gear ring 550, it acts on the external gear ring 550 to make it rotate. The external gear ring 550 drives the material spreading cylinder 530 to rotate, so that the conditioner inside the material spreading cylinder 530 is thrown out through the material spreading holes 540 to achieve uniform spreading. At the same time, a linkage mechanism is established between the external gear ring 550 and the retaining bar 630. The amount of conditioner spread by the rotation of the material spreading cylinder 530 has a certain correlation with the speed of the conveyor belt 620 for transporting saline-alkali soil, which can ensure that the thickness of the saline-alkali soil covered by the conditioner remains certain uniformity.

[0037] In one embodiment, as Figure 1 、 Figure 2 、 Figure 3 and Figure 6 shown, the support portion 570 is rotatably connected to the outer wall of the soil guiding aisle 200. At least one sliding seat portion 910 that can slide thereon is further provided on the outer wall of the soil guiding aisle 200. The sliding seat portion 910 is connected to an adjusting cylinder member 900, and the adjusting cylinder member 900 is connected to the supporting frame 100. In the embodiment of the present invention, the adjusting cylinder member 900 operates and acts on the sliding seat portion 910 through its own expansion and contraction. The sliding seat portion 910 can push one end of the soil guiding aisle 200 and make the soil guiding aisle 200 rotate around the connection with the support portion 570, so as to adjust the front end height of the soil guiding aisle 200 and adjust the depth of plowing the saline-alkali soil by the plowing and pulverizing component 300.

[0038] In one embodiment, as Figures 1-3As shown in the figure, the crushing component 800 includes a crushing rod frame 810 and a plurality of crushing rotating shafts 820. The crushing rod frame 810 is fixed at the tail of the soil guiding aisle 200, and the end of the crushing rod frame 810 away from the soil guiding aisle 200 inclines downward. A plurality of crushing rotating shafts 820 are evenly rotatably arranged on the crushing rod frame 810, and a plurality of crushing star wheels 830 are arranged on each crushing rotating shaft 820. In the embodiment of the present invention, the saline-alkali soil falling from the tail of the soil guiding aisle 200 will fall on the crushing component 800. Due to the impact force of the fall and its own gravity, the saline-alkali soil will act on the crushing star wheels 830, and the crushing rotating shafts 820 and the crushing star wheels 830 will rotate to crush the saline-alkali soil, so that it falls evenly and covers the modifier.

[0039] The above-mentioned embodiment of the invention provides a supporting device for improving saline-alkali soil. Among them, the front end of the entire soil guiding aisle 200 is close to the ground. The feeding component 400 works and drives the ploughing and crushing component 300 to act. The ploughing and crushing component 300 ploughs the saline-alkali land and breaks the hard plough sole formed by stubble removal. At this time, the falling port 210 shovels part of the ploughed saline-alkali soil onto its surface, and the ploughing and crushing component 300 crushes the saline-alkali soil on the shovel plate 220; the crushed saline-alkali soil moves along the soil guiding aisle 200 to the tail of the soil guiding aisle 200 under the rotating feeding of the feeding component 400; and the spreading component 500 at the lower end of the soil guiding aisle 200 works synchronously. The modifier in the modifier storage box 700 enters the inside of the spreading component 500 and is then spread in a rotating manner by the spreading component 500 in the ploughed area; as the entire device moves, the saline-alkali soil at the tail of the soil guiding aisle 200 will fall on the crushing component 800, and the crushing component 800 crushes the saline-alkali soil so that the saline-alkali soil falls and covers the area where the modifier is spilled. The modifier effectively enters the deep part of the saline-alkali soil, fully improves the saline-alkali soil, and the soil above the modifier effectively restricts the volatilization of the modifier. The ploughed saline-alkali land can avoid the loss of the modifier and improve the effect of improving the saline-alkali soil.
