[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] Example 1:

[0027] This utility model provides a combined land preparation machine with soil crushing and leveling functions, including a land preparation machine frame 1;

[0028] A soil-breaking mechanism 2 is installed at the bottom front side of the land preparation machine frame 1, and a soil-leveling mechanism 4 is installed on one side outer wall of the land preparation machine frame 1.

[0029] The soil-crushing mechanism 2 includes a protective box 21, a turning shaft 22, rotary tillers 23, a soil-crushing shaft 24, and an auger 25. The protective box 21 is installed at the bottom of the tillage machine frame 1. The turning shaft 22 and the soil-crushing shaft 24 are both installed on the lower part of the outer surface of the protective box 21 through bearings. Multiple rotary tillers 23 are provided, and multiple rotary tillers 23 are respectively installed on both sides of the outer surface of the turning shaft 22. The arrangement of multiple rotary tillers 23 can expand the turning range and improve the turning efficiency. Two augers 25 are provided, and the two augers 25 are respectively installed on both sides of the outer surface of the soil-crushing shaft 24. The special shape of the auger 25 helps to crush and transport the soil.

[0030] The soil-breaking mechanism 2 also includes a drive assembly 26, a drive shaft 27, a synchronous gear 28, and a synchronous toothed belt 29. The drive assembly 26 is installed on the upper part of one end of the protective box 21. The drive assembly 26 uses a motor or driver to provide power to the entire soil-breaking mechanism 2. The drive shaft 27 is installed between the upper parts of the inner walls on both sides of the protective box 21 through bearings. There are three synchronous gears 28, and the three synchronous gears 28 are respectively installed in the middle of the outer surface of the drive shaft 27, the soil-breaking shaft 24, and the soil-turning shaft 22. The synchronous toothed belt 29 is sleeved and installed between the middle of the outer surface of the three synchronous gears 28. Through the meshing of the synchronous toothed belt 29 with the synchronous gears 28, the synchronous rotation of the drive shaft 27, the soil-breaking shaft 24, and the soil-turning shaft 22 is realized.

[0031] Fixed plates 3 are installed on both sides of the bottom end of the tillage machine frame 1, and the two fixed plates 3 are respectively installed at both ends of the soil crushing mechanism 2 to fix the soil crushing mechanism 2 and prevent it from shaking during operation. Reinforcing frames 5 are installed between the four inner walls of the tillage machine frame 1, and a traction mounting frame 6 is installed on the other outer wall of the tillage machine frame 1. The traction mounting frame 6 is used to connect tractors and other traction equipment to realize the mobile operation of the tillage machine.

[0032] The reinforcing frame 5 is designed with a cross-shaped structure. The cross-shaped reinforcing frame 5 further enhances the structural strength of the grounding machine frame 1 and ensures stability during operation. The bottom end of the reinforcing frame 5 is installed on the top of the protective box 21. The inner side of the synchronous toothed belt 29 has multiple tooth grooves that mesh with the synchronous gear 28 to ensure the stability and accuracy of power transmission.

[0033] Working principle: When the drive assembly 26 is started, the drive shaft 27 drives the synchronous gear 28 installed on it to rotate. The synchronous gear 28 transmits synchronous power to the other two synchronous gears 28 installed on the soil crushing shaft 24 and the soil turning shaft 22 through the synchronous toothed belt 29, realizing the linkage rotation of the soil turning shaft 22 and the soil crushing shaft 24. When the soil turning shaft 22 rotates, the multiple rotary tillage blades 23 installed on both sides of its outer surface perform preliminary tillage and crushing of the soil, breaking large soil clods into smaller soil clods. When the soil crushing shaft 24 rotates, the two spiral augers 25 installed on both sides of its outer surface perform secondary fine crushing and turning of the preliminary crushed soil, ensuring the uniformity and fineness of soil particles, avoiding the presence of large soil clods or the formation of a plow pan, thereby ensuring the stability of the sowing depth, significantly improving the emergence rate, and enhancing the practicality of the tillage machine. It effectively solves the problems of uneven soil crushing, easy retention of large soil clods, or the formation of a plow pan in existing tillage machines.

[0034] Example 2:

[0035] This embodiment is basically the same as the previous embodiment, except that the leveling mechanism 4 includes a leveling plate 41, adjusting rods 42, adjusting blocks 43, fixing frames 44, and positioning pins 45. There are two adjusting rods 42, two adjusting blocks 43, two fixing frames 44, and two positioning pins 45. The two adjusting rods 42 are movably installed on the lower part of the outer wall of the leveling plate 41 through connecting blocks. The movable installation method ensures that the adjusting rods 42 have a certain range of movement relative to the leveling plate 41. The two adjusting blocks 43 are respectively sleeved and installed on the upper part of the outer wall of the two adjusting rods 42. The adjusting rods 42 can slide up and down in the adjusting blocks 43. The two fixing frames 44 are respectively installed on the outer wall of the two adjusting blocks 43, and one end of the two fixing frames 44 is installed on the outer wall of the leveling machine frame 1, which serves to fix and support the adjusting blocks 43. The two positioning pins 45 are respectively inserted and installed between the corresponding adjusting rods 42 and adjusting blocks 43.

[0036] The leveling plate 41 is designed with an L-shaped structure, which allows the leveling plate 41 to better fit the ground during leveling operations and improve the leveling effect. The outer wall of the adjusting rod 42 has multiple positioning holes that match the positioning pins 45. By inserting the positioning pins 45 into different positioning holes, the relative positions of the adjusting rod 42 and the adjusting block 43 can be fixed, thereby realizing the adjustment of the height of the leveling plate 41.

[0037] Working principle: After the tillage machine completes the soil breaking operation, the leveling mechanism 4 starts working. The leveling plate 41 is set with an L-shaped structure, which can more effectively scrape and compact the soil surface. The operator can change the height and angle of the leveling plate 41 by adjusting the position of the adjusting rod 42 in the adjusting block 43 according to the actual terrain and operation requirements. Specifically, first remove the positioning pin 45 from the adjusting rod 42, and then push or pull the adjusting rod 42 to move it up and down in the adjusting block 43, thereby moving the leveling plate 41 together. The height and angle of the leveling plate 41 can be precisely adjusted. After the leveling plate 41 is adjusted to the appropriate position, two positioning pins 45 are respectively inserted and installed between the corresponding adjusting rod 42 and adjusting block 43, so that the positioning pins 45 pass through the positioning holes through the adjusting rod 42 to fix the position of the leveling plate 41 and prevent it from shifting due to vibration during operation. This design allows the leveling mechanism 4 to be flexibly adjusted according to actual needs to adapt to the leveling requirements of different terrains and soil conditions, ensuring the flatness and uniformity of the soil surface after land preparation, thereby achieving the purpose of leveling the land evenly, improving work efficiency, and providing ideal soil conditions for subsequent sowing operations.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
