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

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

At the same time, a pulley will be set on the driving part where the moving seat is located, and the two ends of the conveyor belt in the belt transmission mechanism will be respectively transmitted to the two pulleys to form a drive connection. Therefore, as the agricultural equipment moves forward, the two moving seats will be driven by the belt transmission relationship, so that the two moving seats move up and down relative to each other along their sliding contact surfaces. While loosening the soil, the impact effect generated by the up and down movement is also used to destroy the compaction in the soil, and the up and down movement of the sliding contact surfaces of the two moving seats is used to bring the soil in the groove out and then send it into the groove, so that the soil can be further refined and loosened, the fineness of the soil is improved, and the repair effect is better.

DETAILED DESCRIPTION

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

[0026] In one embodiment, Figures 1-8 As shown:

[0027] This embodiment provides a grassland soil fertilization and repair device, including agricultural equipment 10, a traveling frame 20, a belt transmission mechanism 30, an auxiliary fertilization mechanism 40 and a fertilization mechanism 50. The traveling frame 20 is connected to the agricultural equipment 10, and the traveling frame 20 is provided with an auxiliary fertilization mechanism 40. The auxiliary fertilization mechanism 40 includes at least two moving seats 410 arranged in the traveling frame 20 and sliding together up and down. The fertilization mechanism 50 includes a fertilizer barrel 510 connected to the traveling frame 20, and the fertilizer barrel 510 is provided with a fertilizer pipe 520. 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 installed on a crankshaft. The crankshaft is connected to the moving wheels of the agricultural equipment 10 through the belt transmission mechanism 30, so that the two moving seats 410 can move with the agricultural equipment 10. At the same time, the belt transmission mechanism 30 is driven down by 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 each other.

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

[0029] The bottom end of the moving seat 410 is embedded in the soil, and the agricultural equipment 10 moves forward with the traveling frame 20, and the traveling frame 20 moves forward with the auxiliary fertilizer mechanism 40 and the fertilizer mechanism 50. At the same time, the agricultural equipment 10 also rotates with the moving wheel. The moving wheel here can be understood as the motor wheel of the agricultural equipment 10 or the ground wheel of the agricultural equipment 10. No matter what kind of wheel it is, a pulley will be set on it or on the rotating shaft where it is located. At the same time, a pulley will be set on the driving part where the moving seat 410 is located, and the two ends of the conveyor belt in the belt transmission mechanism 30 will be respectively driven on the two pulleys to form a drive connection. Therefore, as the agricultural equipment 10 moves forward, the two moving seats 410 will be driven by the belt transmission relationship, so that the two moving seats 410 move up and down relative to each other along their sliding contact surfaces. While loosening the soil, the impact effect generated by the up and down movement is also used to destroy 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) is used to bring the soil in the groove out and then send it back into the groove, so that the soil is further refined and loosened, the fineness of the soil is improved, and the repair effect is better.

[0030] Continuing from the above, the fertilizer pipe 520 applies fertilizer according to the sliding contact surface of the two moving seats 410, and the fertilizer falls on the inclined surface corresponding to the two moving seats 410, and as the two moving seats 410 slide up and down, the fertilizer is mixed into the soil more evenly and accurately. In particular, when the compacted part of the fertilizer falls on the two moving seats 410, it is rubbed to pieces as the two moving seats 410 move up and down, 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 is evenly distributed in the soil.

[0031] like Figure 1 As shown, in consideration of reducing the power equipment, the power source of the moving seat 410 is linked to the agricultural equipment 10 (the agricultural equipment 10 is a simplified diagram in the figure, and the agricultural equipment 10 is a type of agricultural equipment) through a belt transmission mechanism 30 and a crankshaft drive, so that the equipment is simple and synchronous repair operations are achieved under the traction of the agricultural equipment 10.

[0032] In another embodiment, Figure 1 、 Figure 3 as well as Figure 4 As shown, a plowshare assembly 210 is installed on the other side of the traveling frame 20 opposite to the auxiliary fertilizing mechanism 40. The plowshare assembly 210 is composed of an array of multiple plowshares 2101. The auxiliary fertilizing mechanism 40 is divided into several groups. Each plowshare 2101 is relatively arranged on the front side of a group of auxiliary fertilizing mechanisms 40, and each plowshare 2101 is relatively arranged between the sliding contact surfaces of the two moving seats 410. There are several fertilizer pipes 520. Each fertilizer pipe 520 is relatively arranged on the rear side of a group of auxiliary fertilizing mechanisms 40, and each fertilizer pipe 520 is relatively arranged between the sliding contact surfaces of the two moving seats 410.

[0033] In this embodiment, when the grassland soil fertilization and repair device is in use, the bottom of the plowshare assembly 210 and the moving seat 410 are embedded in the soil. When the plowshare 2101 moves forward with the traveling frame 20, a groove (deep plowing) is left on the soil, so that the soil is loosened in advance. As the traveling frame 20 continues to move forward, the moving seat 410 is then brought into the groove. The moving seat 410 continues to move forward along the groove with the traveling frame 20, and is driven by the crankshaft 310 to make the two moving seats 410 sliding together slide up and down, and while sliding up and down, the bottom of the two moving seats 410 frequently rise and fall 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 plowshare 2101 moving forward, and the moving seat 410 lags behind it and enters the soil, 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 embodiment, Figures 4 to 6As shown, first, the traveling frame 20 is set to the shape of a rectangular frame, and secondly, a plurality of rectangular positioning units 220 are formed inside the traveling frame 20 by welding a 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 and contact each other are installed in each positioning unit 220 through two slide rails 230. One end of the moving seat 410 is inclined toward 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 groups of auxiliary fertilizing mechanisms 40 are set through multiple positioning units 220, and multiple plowshares 2101 are set on the front side of the multiple groups of auxiliary fertilizing mechanisms 40, and multiple fertilizer pipes 520 are set on the rear side of the multiple groups of auxiliary fertilizing mechanisms 40. When the traveling frame 20 moves forward with all the plowshares 2101, it also moves forward with multiple groups of auxiliary fertilizing mechanisms 40 and multiple fertilizer pipes 520. Each plowshare 2101 plows a deep groove on the soil in advance, and the two moving seats 410 in each group of auxiliary fertilizing mechanisms 40 are inserted into a groove. Each fertilizer pipe 520 fertilizes the sliding contact surface of the two moving seats 410 of a group of auxiliary fertilizing mechanisms 40, thereby improving work efficiency.

[0036] In another embodiment, Figures 3 to 8 As shown, a row of inclined grooves 4102 are respectively provided on the front and rear surfaces of the moving seat 410 from top to bottom, and the inclined grooves 4102 form a V-shaped discharge area 4103 between the sliding contact surfaces of the two moving seats 410. The V-shaped discharge area 4103 on the rear side faces the discharge end of the fertilizer pipe 520, and the V-shaped discharge area 4103 on the front side faces the plowshare 2101. A plurality of shear grooves 4104 are provided inwardly from the sliding contact surfaces of the two moving seats 410, and each shear groove 4104 corresponds to a shear groove 4104, and each shear groove 4104 is communicated with the corresponding shear groove 4104.

[0037] In this embodiment, when the moving seat 410 is inserted into the soil and moves up and down, part of the soil will be brought into the inclined groove 4102. As the moving seat 410 rises with the inclined groove 4102, the soil is obliquely sprinkled on the soil. At the same time, the inclined groove 4102 is used to bring fertilizer into the soil. After the moving seat 410 is repeatedly raised and lowered, the fertilizer is mixed into the soil surface and the inside of the soil. After the moving seat 410 is repeatedly raised and lowered, the soil flows along the inclined groove 4102 to the V-shaped discharge area 4103, and then is re-molded into the groove by the V-shaped discharge area 4103, thereby improving the treatment of the soil. Frequency, that is, each time the moving seat 410 rises, it will use the inclined groove 4102 to drive part of the soil upward once, and then the soil will fall back into the groove once through the V-shaped discharge area 4103 through the inclined manner of the inclined groove 4102, thereby extending the residence time of the soil on the moving seat 410, improving the loosening quality of the soil, and making the soil repair more refined. In addition, when the fertilizer pipe 520 fertilizes, the fertilizer falls into the inclined grooves 4102 of the two moving seats 410, and then flows from the inclined groove 4102 to the V-shaped discharge area 4103, and is mixed into the groove with the refining soil, further improving the fertilization quality.

[0038] like Figure 4 、 Figure 6 As shown, bearings are embedded at both ends of the fertilizer barrel 510, and a feed port 511 is provided at the top. A spiral agitator 512 is provided in the fertilizer barrel 510, and both ends of the spiral agitator 512 are assembled 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 grassland soil remediation method comprises the following steps:

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

[0041] Step S02: Grooves are formed in the soil by the plowshare 2101, 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 to produce a secondary soil-turning action. The moving seats 410 move up and down relative to each other. In addition to repeatedly processing the soil in the grooves, the fertilizer is also evenly mixed into the soil and finally evenly mixed into the grooves with the soil, thereby improving the quality of fertilization.
