Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a towed high-speed folding land preparation machine. Background Technology

[0002] Land preparation machinery is a type of machinery used in agricultural production to improve soil structure and create a suitable environment for crop growth. Its core functions include loosening soil, breaking up soil, weeding, leveling the ground surface, and mixing fertilizers.

[0003] Existing land preparation machinery typically uses land preparation rollers for loosening or breaking up soil. These rollers rotate via a drive unit and use their surface teeth to break up soil clods. However, when working on wet soil, existing land preparation rollers often result in soil being compacted between the teeth. This compacted soil continues to accumulate during operation, hindering the roller's subsequent breaking-up work. The current method for cleaning land preparation rollers is mostly to wash them with a water gun after a period of tillage. This method is not only difficult to clean in a timely manner but also wastes a significant amount of water resources. Utility Model Content

[0004] This utility model provides a towed high-speed folding land leveling machine to solve the problems in the background art mentioned above, namely:

[0005] Traditional land preparation machinery has difficulty cleaning the soil adhering to the surface of the land preparation roller in a timely manner, which leads to a decrease in the soil breaking effect of the land preparation roller.

[0006] To achieve the above objectives, the towed high-speed folding land leveling machine includes a tow machine, a mounting frame, and a land leveling roller. The mounting frame is fixedly connected to one end of the tow machine, and the land leveling roller is rotatably connected inside the mounting frame. Several rows of soil-crushing teeth are fixedly connected to the outside of the land leveling roller. An installation rod is fixedly connected to one end of the mounting frame, and a connecting plate is provided on the outside of the installation rod. A scraper is provided at the bottom of the connecting plate.

[0007] In the above technical solution, the end of the scraper blade is attached to the surface of the leveling roller and distributed in the gap between adjacent rows of soil-breaking teeth, for scraping away the soil stuck in the gap between the soil-breaking teeth when the leveling roller rotates.

[0008] Based on this, the soil-breaking teeth in adjacent columns are staggered to reduce the adhesion of soil in the gaps.

[0009] In another technical solution, a lower fixing member is fixedly connected to the top of the connecting plate, and an upper fixing member is provided above the connecting plate. By adjusting the positions of the upper and lower fixing members on the mounting rod, the scraper blade is aligned with the gap of the soil-breaking teeth on the surface of the leveling roller of different sizes.

[0010] The bottom of the connecting plate has two connecting holes, and the top of the scraper has two adjusting grooves. The connecting holes are threaded with adjusting bolts. By sliding the adjusting bolts in the adjusting grooves, the end of the scraper can be made to fit the surface of the leveling roller with different outer diameters.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this traction-type high-speed folding land leveling machine, the synergistic action of the scraper blade and the staggered soil-breaking teeth effectively solves the problem of soil getting stuck in the gaps between the soil-breaking teeth in the existing technology. During the rotation of the land leveling roller, the end of the scraper blade is in real time in contact with the roller surface, automatically scraping away the compacted soil stuck in the gaps between adjacent soil-breaking teeth, avoiding the tedious operation of frequent manual cleaning or water gun washing. At the same time, the staggered distribution design of the soil-breaking teeth makes the stuck soil easier to fall off naturally due to the lack of unilateral support, further improving the cleaning efficiency and ensuring that the land leveling roller works continuously and efficiently.

[0013] 2. In this traction-type high-speed folding land preparation machine, the upper and lower fixing parts enable the scraper blade to quickly adapt to land preparation rollers of different sizes. The position of the connecting plate can be flexibly adjusted along the mounting rod. The fit between the scraper blade and the land preparation roller can be fixed by the adjusting groove and the locking nut, thereby ensuring that the scraper blade is always in close contact with the surface of the land preparation roller, adapting to the needs of different farming scenarios.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Currently, traditional land preparation machinery struggles to promptly remove soil adhering to the surface of the land preparation rollers, leading to a decrease in the rollers' soil-breaking effect. This invention provides a towed, high-speed folding land preparation machine. (See attached image) Figure 1 - Figure 2 As shown, the device includes a traction machine 1, a mounting frame 2, and a leveling roller 3. The mounting frame 2 is fixedly connected to one side of the traction machine 1, and the leveling roller 3 is rotatably connected to the inside of the mounting frame 2. Multiple rows of soil-crushing teeth 31 are fixedly connected to the outer surface of the leveling roller 3. A mounting rod 21 is fixedly connected to one side of the mounting frame 2. Multiple connecting plates 4 are provided on the outside of the mounting rod 21. Each of the multiple connecting plates 4 is provided with a scraper 5 at one end. The multiple scraper 5 are distributed among the rows of soil-crushing teeth 31, and one end is attached to the surface of the leveling roller 3. During the operation of the leveling roller 3, the leveling roller 3 is driven to rotate continuously by the driving device. At this time, the scraper 5 remains fixed, thereby scraping away the soil that enters the gaps between the soil-crushing teeth 31, achieving the effect of timely cleaning.

[0026] Furthermore, refer to Figure 2 As shown, multiple sets of soil-breaking teeth 31 are staggered on the outside of the leveling roller 3, that is, they are not in the same column and two adjacent soil-breaking teeth 31 are not on the same horizontal line. In this way, when soil gets stuck between the rows of soil-breaking teeth 31, one side of the soil will lack the support of the soil-breaking teeth 31, making it easier for it to fall off naturally or be scraped off by the scraper plate 5 during the rolling of the leveling roller 3.

[0027] When implementing, refer to Figure 3 As shown, a lower fixing member 41 is fixedly connected to the top of the connecting plate 4, and an upper fixing member 42 is provided above the connecting plate 4. A fixing bolt 43 is threaded through the top of the upper fixing member 42. The upper fixing member 42 is detachably connected to the lower fixing member 41 through the fixing bolt 43. Both the upper fixing member 42 and the lower fixing member 41 are provided on the outside of the mounting rod 21.

[0028] When different sizes of tillage rollers 3 are replaced due to the requirements of cultivated land, the position of the gaps between the soil-crushing teeth 31 on the outside of the tillage roller 3 will also be different. By sliding the upper fixing part 42 and the lower fixing part 41 on the mounting rod 21, the position of the scraper 5 can be indirectly changed so that the scraper 5 can correspond to the gaps between the rows of soil-crushing teeth 31 to adapt to different sizes of tillage rollers 3. After the adjustment is completed, the lower fixing part 41 and the upper fixing part 42 can be fixed on the mounting rod 21 by fixing bolts 43.

[0029] Furthermore, when different sizes of leveling rollers 3 are replaced, the outer diameter of leveling rollers 3 will also change. To ensure that the scraper blade 5 always adheres to the outer surface of the leveling roller 3, refer to... Figure 4 As shown, two connecting holes 44 are provided through the bottom of the connecting plate 4, and two adjusting grooves 51 are provided through the top of the scraper 5. The positions of the two adjusting grooves 51 correspond to the positions of the two connecting holes 44. Adjusting bolts 52 are threaded through the inside of the connecting holes 44. The adjusting bolts 52 are slidably connected to the adjusting grooves 51 and locked. One end of the adjusting bolts 52 is threadedly connected to a locking nut 53, which is located on the bottom surface of the scraper 5.

[0030] When installing the scraper blade 5, the user first ensures that the positions of the two adjustment grooves 51 on the scraper blade 5 correspond to the positions of the two connecting holes 44 respectively. Then, the user slides the scraper blade 5 along the longer side of the adjustment groove 51, adjusting the direction of the scraper blade 5 until one end of the scraper blade 5 can contact the outer surface of the leveling roller 3. After that, the user inserts the adjusting bolt 52 into the connecting hole 44 and the adjustment groove 51, and fixes the adjusting bolt 52 with the locking nut 53 on the other side of the scraper blade 5. In this way, the scraper blade 5 can be made to fit the outer surface of leveling rollers 3 of different sizes.

[0031] The working principle of this device is as follows:

[0032] First, after installing the leveling roller 3, the user adjusts the upper fixing member 42 and the lower fixing member 41 on the mounting rod 21 according to the distribution position of each row of soil-breaking teeth 31 on the leveling roller 3, until the connecting plate 4 is located in the gap between the two rows of soil-breaking teeth 31. Then, the user can use the fixing bolt 43 to fix the upper fixing member 42 and the lower fixing member 41 to the mounting rod 21. Repeat the above steps until all the connecting plates 4 are in the gap between the two rows of soil-breaking teeth 31. Then, the user first aligns the positions of the two adjusting grooves 51 on the scraper 5 with the positions of the two connecting holes 44 respectively. Then, the user slides the scraper 5 along the direction of the longer groove side of the adjusting groove 51, adjusting the direction of the scraper 5 until one end of the scraper 5 can contact the outer surface of the leveling roller 3. Finally, the user inserts the adjusting bolt 52 into the connecting hole 44 and the adjusting groove 51, and uses the locking nut 53 to fix the adjusting bolt 52 on the other side of the scraper 5 to complete the installation.

[0033] During tillage, if soil gets stuck in the gaps between the rows of soil-breaking teeth 31, the soil will be unstable due to the misaligned distribution of the soil-breaking teeth 31 and the lack of support on one side. At this time, as the tillage roller 3 rotates, some of the loose soil will fall out of the gaps naturally, while the other part of the compacted soil will be scraped off by the scraper 5, achieving a cleaning effect.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
