Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and in particular to a device and method for fertilizing and restoring grassland soil. Background Technology

[0002] Grassland soil fertilization and remediation refers to the process of improving the physical, chemical, and biological properties of degraded grassland soil through the application of various fertilizers and amendments, in order to restore and enhance the productivity and ecological functions of the grassland. Patent application number CN202411904657.0 discloses a root-cutting device and remediation method for degraded Leymus chinensis grassland. The root-cutting device has a suspension frame on its frame, which is configured to move with a traction device across the Leymus chinensis grassland. The walking frame also has a perforation component, a root-cutting component, and a fertilization component arranged sequentially along the walking direction. The disclosed root-cutting component is a rotary cutting structure that penetrates the soil to cut the roots. The fertilization outlet pipe is located between the two sets of root-cutting components for simultaneous fertilization.

[0003] The fertilizer application pipes are spaced apart, and the fertilizer application method is a single flow method. The soil is treated only by a rotary cutter. There is no matching relationship between the rotary cutter and the fertilizer application pipe. When the rotary cutter penetrates into the soil, it only damages the root system in the soil. It cannot use its rotary cutting action to help the fertilizer be evenly mixed into the soil. Moreover, the soil cannot be refined by rotary cutting alone. The remediation method needs to be improved. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a grassland soil fertilization and remediation device, comprising agricultural equipment, a traveling frame, a belt drive mechanism, an auxiliary fertilization mechanism, and a fertilization mechanism. The traveling frame is connected to the agricultural equipment, and the auxiliary fertilization mechanism is mounted on the traveling frame. The auxiliary fertilization mechanism includes at least two moving seats disposed within the traveling frame and sliding together vertically. The top ends of the two moving seats are jointly mounted on a crankshaft. The fertilization mechanism includes a fertilization cylinder connected to the traveling frame, and a fertilization pipe is provided on the fertilization cylinder. The fertilization pipe is inclined downward and close to the two moving seats. The outer end of the crankshaft is connected to the moving wheel of the agricultural equipment through the belt drive mechanism, so that the two moving seats move with the agricultural equipment and, through the belt drive mechanism, move vertically relative to the soil and the discharge port of the fertilization pipe.

[0005] As a further preferred embodiment, a plowshare assembly is installed on the side of the traveling frame opposite to the side where the auxiliary fertilization mechanism is installed. The plowshare assembly is an array of multiple plowshares. The auxiliary fertilization mechanism consists of several groups, with each plowshare positioned opposite each other on the front side of a group of auxiliary fertilization mechanisms and positioned opposite each other between the sliding contact surfaces of the two moving seats. The fertilizer tube consists of several tubes, with each fertilizer tube positioned opposite each other on the rear side of a group of auxiliary fertilization mechanisms and positioned opposite each other between the sliding contact surfaces of the two moving seats.

[0006] As a further preferred embodiment, the top of the traveling frame is provided with an assembly hole, and bearings are installed at both ends of the assembly hole. The auxiliary fertilization mechanism also includes a crankshaft mounted on the top of the traveling frame via bearings. The top of the moving seat is provided with a lifting lug, which is movably connected to the crankshaft. When the crankshaft rotates, the two moving seats of the auxiliary fertilization mechanism move up and down relative to each other through the lifting lug.

[0007] As a further preferred embodiment, the traveling frame has a rectangular frame, and multiple rectangular positioning units are formed inside by welding steel structures. Each positioning unit has a slide rail on both sides, and two moving seats that slide and contact each other are installed in each positioning unit through the two slide rails. One end of the moving seat is inclined toward the rear side of the bottom end of the fertilizer pipe and extends beyond the bottom end of the traveling frame.

[0008] As a further preferred embodiment, each of the front and rear sides of the motion seat has a row of inclined grooves from top to bottom. The inclined grooves form a V-shaped discharge area between the sliding contact surfaces of the two motion seats. The V-shaped discharge area on the rear side faces the discharge end of the fertilizer pipe, and the V-shaped discharge area on the front side faces the plowshare. A plurality of shearing grooves are formed inward from the sliding contact surfaces of the two motion seats. Each shearing groove corresponds to one shearing groove, and each shearing groove communicates with the corresponding shearing groove.

[0009] As a further preferred embodiment, the fertilizer cylinder is equipped with bearings at both ends and a feed inlet at the top. A spiral agitator is installed inside the fertilizer cylinder, with both ends of the spiral agitator mounted on the bearings. One end of the spiral agitator is connected to the moving wheel of the agricultural equipment via a pulley and a conveyor belt.

[0010] This invention also provides a method for grassland soil remediation, comprising the following steps:

[0011] Step S01: Connect the grassland soil fertilization and remediation device to the agricultural equipment through the front end of the traveling frame to provide power;

[0012] Step S02: The plowshare forms a trench in the soil, and fertilizer is applied by the sliding contact surface of the fertilizer pipe relative to the two moving seats. The fertilizer enters the soil through the secondary turning action generated by the up-and-down sliding of the moving seats, which improves the quality of fertilization.

[0013] The advantages of this invention compared to the prior art are:

[0014] 1. A traveling frame is installed on agricultural equipment. A plowshare is mounted on one side of the traveling frame, and a moving seat is mounted on the other side. The moving seat consists of multiple arrays of two pieces sliding together vertically, creating a shearing motion relative to the soil as the traveling frame moves. A crankshaft is located at the top of the moving seat and connected to the moving wheels of the agricultural equipment via a crankshaft and connecting rod structure. The fertilizer tube is located on the shearing surface of the moving seat. When the agricultural equipment moves forward with the plowshare, the connecting rod structure drives the crankshaft to rotate, which in turn drives the moving seat to slide up and down. The bottom of the moving seat is embedded in the soil. The two moving seats slide up and down at their contact surface, breaking up compacted soil clumps. Secondly, the sliding of the fertilizer tube relative to the two moving seats applies fertilizer, ensuring that the fertilizer is evenly mixed into the soil, thus improving the quality of fertilization.

[0015] 2. The bottom of the moving seat is embedded in the soil. The agricultural equipment moves forward with the traveling frame, which in turn carries the auxiliary fertilization mechanism and the fertilization mechanism. At the same time, the agricultural equipment also rotates the moving wheels. These moving wheels can be understood as the motor wheels or ground wheels of the agricultural equipment. Regardless of the type of wheel, pulleys are installed on them or on their respective shafts. Pulleys are also installed on the drive unit where the moving seat is located. The two ends of the conveyor belt in the belt drive mechanism are respectively driven by two pulleys to form a drive connection. Therefore, as the agricultural equipment moves forward, it drives the two moving seats through the belt drive relationship, causing the two moving seats to move up and down along their sliding contact surfaces. While loosening the soil, the impact effect generated by the up and down movement also breaks up the compacted soil. The up and down movement of the sliding contact surfaces of the two moving seats carries the soil out of the trench and then sends it back into the trench, thereby achieving the purpose of further refining and loosening the soil. The soil fineness is improved, and the restoration effect is better. Attached Figure Description

Detailed Implementation

[0025] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] In one implementation, such as Figures 1-8 As shown:

[0027] This embodiment provides a grassland soil fertilization and remediation device, including agricultural equipment 10, a traveling frame 20, a belt drive mechanism 30, an auxiliary fertilization mechanism 40, and a fertilization mechanism 50. The traveling frame 20 is connected to the agricultural equipment 10. The auxiliary fertilization mechanism 40 is provided on the traveling frame 20. The auxiliary fertilization mechanism 40 includes at least two moving seats 410 disposed within the traveling frame 20 and sliding together vertically. The fertilization mechanism 50 includes a fertilizer cylinder 510 connected to the traveling frame 20. A fertilizer pipe 520 is provided on the fertilizer cylinder 510. The fertilizer pipe 520 is inclined downward and close to the sliding contact surface of the two moving seats 410. The top ends of the two moving seats 410 are jointly mounted on a crankshaft. The crankshaft is connected to the moving wheel of the agricultural equipment 10 through the belt drive mechanism 30, so that the two moving seats 410 move with the agricultural equipment 10 and also drive the belt drive mechanism 30 downward through the moving wheel, so that the two moving seats 410 move up and down relative to the soil and the discharge port of the fertilizer pipe 520 along the sliding contact surface between them.

[0028] The top of the traveling frame 20 is provided with an assembly hole, and bearings are installed at both ends of the assembly hole. The auxiliary fertilization mechanism 40 also includes a crankshaft 310 installed at the top of the traveling frame 20 via bearings. The top of the moving seat 410 is provided with a lifting lug 4101, which is movably connected to the crankshaft 310. When the crankshaft 310 rotates, the two moving seats 410 of the auxiliary fertilization mechanism 40 move up and down relative to each other through the lifting lug 4101.

[0029] The bottom of the motion seat 410 is embedded in the soil. The agricultural equipment 10 moves forward with the traveling frame 20, which in turn moves the auxiliary fertilization mechanism 40 and the fertilization mechanism 50. Simultaneously, the agricultural equipment 10 rotates its moving wheels. These moving wheels can be understood as either the motorized wheels or the ground wheels of the agricultural equipment 10. Regardless of the type of wheel, pulleys are installed on them or on their respective shafts. Additionally, pulleys are installed on the drive unit where the motion seat 410 is located, connecting the two ends of the conveyor belt in the belt drive mechanism 30 to the two pulleys to form a drive connection. Therefore, as the agricultural equipment 10 moves forward, it drives the two moving seats 410 through the belt drive, causing the two moving seats 410 to move up and down along their sliding contact surfaces. While loosening the soil, the impact effect generated by the up and down movement also breaks up the compaction in the soil. The up and down movement of the sliding contact surfaces of the two moving seats 410 (when one moving seat 410 slides upward, the other moving seat 410 slides downward) carries the soil out of the trench and then back into the trench, thereby achieving the purpose of further refining and loosening the soil. The fineness of the soil is improved, and the repair effect is better.

[0030] As described above, the fertilizer applicator 520 applies fertilizer to the sliding contact surfaces of the two moving seats 410. The fertilizer falls onto the inclined surfaces of the two moving seats 410 and is mixed into the soil more evenly and accurately as the two moving seats 410 slide up and down. In particular, when the compacted part of the fertilizer falls onto the two moving seats 410, it is rubbed into pieces by the up and down movement of the two moving seats 410, and then mixed into the soil along the surface of the two moving seats 410 and the movement of the two moving seats 410, so that the fertilizer achieves the purpose of even distribution in the soil.

[0031] like Figure 1 As shown, considering the reduction of power equipment, the power source of the motion seat 410 is linked to the agricultural equipment 10 (the agricultural equipment 10 in the figure is a simplified drawing, and the agricultural equipment 10 is a type of agricultural equipment) through the belt transmission mechanism 30 and crankshaft drive, which simplifies the equipment and enables synchronous repair operations under the traction of the agricultural equipment 10.

[0032] In another implementation, such as Figure 1 , Figure 3 as well as Figure 4 As shown, a plowshare assembly 210 is installed on the side of the traveling frame 20 opposite to the side where the auxiliary fertilization mechanism 40 is installed. The plowshare assembly 210 is an array of multiple plowshares 2101. The auxiliary fertilization mechanism 40 consists of several groups. Each plowshare 2101 is positioned opposite to the front of a group of auxiliary fertilization mechanisms 40 and is positioned opposite to the sliding contact surface of two moving seats 410. There are several fertilizer pipes 520. Each fertilizer pipe 520 is positioned opposite to the rear of a group of auxiliary fertilization mechanisms 40 and is positioned opposite to the sliding contact surface of two moving seats 410.

[0033] In this embodiment, when the grassland soil fertilization and restoration device is used, the plow assembly 210 and the bottom of the moving seat 410 are embedded in the soil. As the plow 2101 moves forward with the traveling frame 20, it leaves a groove (deep tillage) in the soil, which loosens the soil in advance. As the traveling frame 20 continues to move forward, it brings the moving seat 410 into the groove. The moving seat 410 moves along the groove with the traveling frame 20 and is driven by the crankshaft 310, causing the two moving seats 410 that are sliding together to slide up and down. While sliding up and down, the bottom of the moving seat 410 frequently rises and falls in the groove. At the same time, the two moving seats 410 frequently rise and fall relative to the sliding contact surface. The groove is obtained in advance by the plow 2101, and the moving seat 410 enters the soil later, thereby reducing the working pressure of the moving seat 410 in the soil and improving the service life of the moving seat 410.

[0034] In another implementation, such as Figures 4 to 6As shown, the traveling frame 20 is first set into the shape of a rectangular frame. Then, multiple rectangular positioning units 220 are formed inside the traveling frame 20 by welding steel structure. In order to ensure that the moving seat 410 moves more smoothly, a slide rail 230 is provided on both sides of each positioning unit 220. Two moving seats 410 that slide together are installed in each positioning unit 220 through the two slide rails 230. One end of the moving seat 410 is inclined towards the rear side of the bottom end of the fertilizer pipe 520 and extends beyond the bottom end of the traveling frame 20 to penetrate into the soil.

[0035] In this embodiment, multiple sets of auxiliary fertilization mechanisms 40 are set through multiple positioning units 220, and multiple plowshares 2101 are set on the front side of the multiple sets of auxiliary fertilization mechanisms 40, and multiple fertilizer pipes 520 are set on the rear side of the multiple sets of auxiliary fertilization mechanisms 40. When the traveling frame 20 moves forward with all the plowshares 2101, it will also move forward with the multiple sets of auxiliary fertilization mechanisms 40 and the multiple fertilizer pipes 520. Each plowshare 2101 pre-cultivates a furrow in the soil, and two moving seats 410 in each set of auxiliary fertilization mechanisms 40 are inserted into a furrow. Each fertilizer pipe 520 applies fertilizer to the sliding contact surface of the two moving seats 410 of a set of auxiliary fertilization mechanisms 40, thereby improving work efficiency.

[0036] In another implementation, such as Figures 3 to 8 As shown, a row of inclined grooves 4102 is opened from top to bottom on the front and rear sides of the motion seat 410. The inclined grooves 4102 form a V-shaped discharge area 4103 between the sliding contact surfaces of the two motion seats 410. The rear V-shaped discharge area 4103 faces the discharge end of the fertilizer pipe 520, and the front V-shaped discharge area 4103 faces the plowshare 2101. A number of shearing grooves 4104 are opened inward from the sliding contact surfaces of the two motion seats 410. Each shearing groove 4104 corresponds to a shearing groove 4104, and each shearing groove 4104 is connected to the corresponding shearing groove 4104.

[0037] In this embodiment, when the moving seat 410 is driven into the soil and moves up and down, some soil is carried into the inclined trough 4102. As the moving seat 410 rises with the inclined trough 4102, the soil is obliquely sprinkled onto the soil surface. At the same time, fertilizer is carried into the soil by the inclined trough 4102. Through repeated up-and-down movements of the moving seat 410, fertilizer is mixed into both the soil surface and the soil interior. After repeated up-and-down movements of the moving seat 410, the soil flows along the inclined trough 4102 to the V-shaped discharge area 4103, and then is recycled back into the trench from the V-shaped discharge area 4103, thus improving soil treatment efficiency. The frequency, that is, every time the motion seat 410 rises, it uses the inclined chute 4102 to carry a part of the soil upward once, and then the soil falls back into the trench through the V-shaped discharge area 4103 by the inclined chute 4102. This prolongs the residence time of the soil on the motion seat 410, improves the quality of soil loosening, and makes the soil remediation more refined. In addition, when the fertilizer pipe 520 applies fertilizer, the fertilizer falls into the inclined chute 4102 of the two motion seats 410, and then flows from the inclined chute 4102 to the V-shaped discharge area 4103, and is mixed into the trench with the soil being refined, which further improves the quality of fertilization.

[0038] like Figure 4 , Figure 6 As shown, the fertilizer cylinder 510 has bearings embedded at both ends and a feed inlet 511 at the top. The fertilizer cylinder 510 is equipped with a spiral agitator 512. The two ends of the spiral agitator 512 are mounted on the bearings. One end of the spiral agitator 512 is connected to the moving wheel of the agricultural equipment 10 through a pulley and a conveyor belt.

[0039] A method for grassland soil remediation includes the following steps:

[0040] Step S01: Connect the grassland soil fertilization and remediation device to the agricultural equipment 10 via the front end of the traveling frame 20 to provide power;

[0041] Step S02: The plowshare 2101 forms a trench in the soil, and fertilizer is applied by the sliding contact surface of the fertilizer pipe 520 relative to the two moving seats 410. The fertilizer enters the soil as the moving seats 410 slide up and down, generating a secondary soil turning action. The moving seats 410 move up and down with each other, which not only repeatedly processes the soil in the trench, but also mixes the fertilizer evenly into the soil. Finally, the fertilizer is evenly mixed into the trench along with the soil, which improves the quality of fertilization.
