However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a moisture-conserving plow for terraced grain planting in hilly and mountainous areas, including a mounting frame 1. A power conversion component 2 is fixedly installed at the rear end of the mounting frame 1. Movable cylinders 9 are movably installed at both ends of the power conversion component 2. Stabilizing columns 3 are fixedly installed at one end of each of the two sets of movable cylinders 9. Elliptical seats 4 are fixedly installed at the other end of each of the two sets of stabilizing columns 3. A main plowshare 5 is fixedly installed at the lower end of the mounting frame 1. Long blocks 6 are fixedly installed at one end of each of the two sets of elliptical seats 4. Multiple sets of auxiliary plowshares 7 are fixedly installed at the front end of each set of long blocks 6. A rotating rod 12 is rotatably mounted through one end of the lower protrusion of the movable cylinder 9. A detachable disc plow blade 13 is mounted on the outer wall of each set of rotating rods 12. The other ends of the two sets of long blocks 6 are respectively fixed to one end of the lower protrusion of the two sets of movable cylinders 9. The other ends of the two sets of rotating rods 12 are rotatably mounted inside the two sets of elliptical seats 4. A stabilizing frame 10 is fixedly mounted on the upper end of the mounting frame 1. Limiting plates 11 are rotatably mounted on both ends of the stabilizing frame 10. The other ends of the two sets of limiting plates 11 are rotatably connected to the outer wall of the upper protrusion of the two sets of stabilizing columns 3.

[0022] The specific settings and functions of this embodiment are described below. The main plowshare 5, which is fixedly installed at the lower end of the mounting base 1, is made of high chromium alloy. Its plowshare surface is designed as an Archimedean spiral surface based on the principles of soil mechanics. This design can produce efficient soil breaking and turning effects. The long blocks 6, which are rectangular hollow steel pipes, are fixedly installed at one end of the two sets of elliptical seats 4. The front end of each set of long blocks 6 is fixedly installed with four sets of auxiliary plowshares 7 by bolt array. The auxiliary plowshares 7 are made of tungsten carbide alloy blades with a cutting edge angle of 25°. They can perform secondary crushing of the soil turned up by the main plowshare 5 to reduce the diameter of soil particles.

[0023] Two sets of movable cylinders 9 each have a rotating rod 12 mounted on one end of their lower protrusions. The rotating rod 12 has a spline shaft structure and forms a precise fit with the spline hole of the disc plow blade 13 to ensure stable power transmission. Each set of rotating rods 12 has a detachable disc plow blade 13 mounted on its outer wall. The disc plow blade 13 has a double-curved surface design and a hardness of HRC55-60 after edge quenching. Its surface is equipped with a spiral soil-breaking blade. When encountering obstacles such as rocks and tree roots, it can avoid them by rotating and rolling. It can cross obstacles with a maximum diameter of 15cm, reducing resistance and wear, and adapting to the complex soil environment of hilly and mountainous areas. The other ends of the two sets of long blocks 6 are fixed to one end of the lower protrusions of the two sets of movable cylinders 9 by flanges and high-strength bolts. The other ends of the two sets of rotating rods 12 are rotatably mounted inside the two sets of elliptical seats 4 by deep groove ball bearings to ensure the stability and reliability of the rotation of the disc plow blade 13.

[0024] The combination of the main plowshare 5, the auxiliary plowshare 7, and the detachable disc plowshare 13 forms a three-level high-efficiency tillage system. The main plowshare 5 adopts a high-chromium alloy Archimedes spiral surface design, which, together with the tungsten carbide alloy blades of the auxiliary plowshare 7 and the hyperboloid detachable disc plowshare 13, powerfully breaks and turns the soil, the auxiliary plowshare 7 refines the soil, and the disc plowshare 13 flexibly responds to obstacles. It can completely break up the compacted soil layer up to 35cm deep, improve soil porosity, effectively improve soil aeration and permeability, and enhance the soil's water and fertilizer retention capacity. This creates a loose and fertile soil environment for the growth of grain roots, improving soil moisture retention efficiency compared to traditional plows.

[0025] Stable and reliable structure: The stabilizing column 3, elliptical seat 4, stabilizing frame 10 and limiting plate 11 work together to form a stable frame structure, which enhances the stability of the plow when working on complex terrain, reduces the loosening of parts or tillage deviation caused by terrain bumps, and ensures normal operation and service life of the plow.

[0026] Flexible and replaceable parts: The disc plow blade 13 adopts a detachable design, which can quickly replace the appropriate disc plow blade 13 when encountering different soil conditions or when wear occurs, improving the versatility and practicality of the plow and reducing the cost of use and maintenance difficulty.

[0027] By setting a transmission component inside the stabilizing column 3 and the elliptical seat 4, and fixing the output ends of the transmission component and the power conversion component 2 at both ends, and fixing the two transmission ends of the transmission component to one end of the two sets of rotating rods 12 respectively, the power conversion component 2 can convert the power on the tractor and transmit the power to the two sets of rotating rods 12 through the transmission component, so that the rotating rods 12 can drive multiple sets of disc plow blades 13 to rotate, which facilitates further crushing of the soil.

[0028] Example 2: Figure 1 Diagram and Figure 3As shown, both ends of the mounting base 1 are provided with adjusting screw cylinders 8. The interior of both sets of adjusting screw cylinders 8 is threaded with threaded rods 14. One end of each set of adjusting screw cylinders 8 and each set of threaded rods 14 is fixedly installed with a movable head 15. The outer walls of each set of adjusting screw cylinders 8 are provided with two sets of symmetrically arranged limiting rods 16. One end of each set of movable heads 15 is rotatably connected to the recesses at both ends of the mounting base 1. The other two sets of movable heads 15 are rotatably connected to the outer wall mating seats of each set of stabilizing columns 3.

[0029] The overall effect of this embodiment is as follows: a stabilizing frame 10 is fixedly installed on the upper end of the mounting base 1; limiting plates 11 are rotatably installed on both ends of the stabilizing frame 10; and the other end of the limiting plate 11 is rotatably connected to the outer wall of the protrusion on the stabilizing column 3, further enhancing the overall stability of the plow. In the adjustment mechanism, adjusting screw cylinders 8 are provided at both ends of the mounting base 1; threaded rods 14 are internally connected to the adjusting screw cylinders 8; and movable heads 15 are fixedly installed on one end of both the adjusting screw cylinders 8 and the threaded rods 14. Two sets of movable heads 15 are rotatably connected to the recesses at both ends of the mounting base 1, and the other two sets of movable heads 15 are rotatably connected to the stabilizing column 3. The outer wall of column 3 is rotatably connected to the seat; at the same time, two sets of limiting rods 16 are symmetrically installed on the outer wall of adjusting screw cylinder 8. By rotating adjusting screw cylinder 8, the extension length of threaded rod 14 can be changed, thereby adjusting the position and angle of stabilizing column 3, realizing flexible adjustment of the tilt angle of auxiliary plowshare 7, so as to adapt to different terrains and cultivation needs of hilly and mountain terraces. It can accurately adjust the soil penetration depth and tilt angle of plow body according to the varying slopes and terrains of hilly and mountain terraces, ensuring consistent cultivation depth, avoiding the problem of some areas being cultivated too deep or too shallow, and effectively improving cultivation quality and moisture retention effect;

[0030] The setting of the limit rod 16 makes it convenient for the user to rotate the adjusting screw 8.

[0031] The usage and working principle of this device are as follows: First, the moisture-preserving plow is connected to the traction equipment (such as a tractor) through the front end of the mounting frame 1. The linear travel power provided by the traction equipment is transmitted to the power conversion component 2 at the rear end of the mounting frame 1. The gear transmission mechanism inside the power conversion component 2 converts the linear power into a composite motion power suitable for the plow's operation. Then, when facing different slopes and terrain changes in hilly and mountainous terraced fields, it is necessary to adjust the tilt angle of the auxiliary plowshare 7 to ensure the tillage effect. At this time, the operator precisely changes the tilt angle by rotating the adjusting screws 8 at both ends of the mounting frame 1, utilizing the trapezoidal thread transmission principle. The extension length of the threaded rod 14, when the length of the threaded rod 14 changes, drives the stabilizing column 3 to make fine adjustments in position and angle, which facilitates cultivation inside the terrace. Finally, after cultivation by the main plowshare 5, the auxiliary plowshare 7 and the disc plow 13, the soil structure is significantly improved, creating good conditions for moisture retention. On the one hand, the loose and finely granulated soil is more conducive to water infiltration and storage, reducing water loss caused by surface runoff. On the other hand, the broken weeds and crop residues are evenly mixed into the soil during cultivation, forming a humus cover layer during subsequent natural decomposition, effectively reducing soil moisture evaporation.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
