Description

Technical Field

[0001] The invention belongs to the technical field of farmland reclamation, and in particular relates to high-standard farmland reclamation land leveling equipment. Background Art

[0002] Land leveling is a key link in high-standard farmland reclamation. Its quality directly affects subsequent farming operations such as cultivation, irrigation, fertilization, and the growth and development of crops. When cultivating the land, leveling the land is a heavy physical work. It is difficult to ensure the flatness of the land using ordinary tools. Currently, agricultural vehicles and farming machinery are generally used to level the land while the vehicles are moving forward. Although the existing land leveling equipment in life has met the needs of users to a certain extent, there are still certain defects in the use process. The specific problems are as follows: it is impossible to effectively remove stones and residual roots hidden deep in the soil. In subsequent farming operations, the stones will not only affect the flatness of the soil, but also hinder the smooth flow of water, making it impossible for irrigation water to penetrate evenly, affecting the growth of crops. Various pathogens and pests may remain in the residual roots. If the residual roots are not effectively removed, over time, not only will the risk of disease and pest transmission be greatly increased, but it will also occupy soil space, hindering the normal growth and extension of crop roots, resulting in the root system being unable to fully absorb nutrients and water in the soil, reducing the stress resistance and yield of crops; In order to solve the above problems, this application proposes a high-standard farmland reclamation and land leveling equipment.

[0023] A crushing assembly 6 is installed on the rear side of the lower surface of the traction rake body 1, and the crushing assembly 6 includes a crushing box 61, a crushing shaft 62, a crushing tooth 63, a lower hopper 64, a synchronous chain 65, a transmission gear 66, a support frame 67, a leveling roller 68 and a scraper 69; A crushing box 61 is arranged directly below the filter stone mesh plate two 48, and the crushing box 61 is fixed on the lower surface of the traction harrow body 1. Two crushing shafts 62 are rotatably connected inside the crushing box 61. Crushing teeth 63 are fixed on the surfaces of the two crushing shafts 62, and the two sets of crushing teeth 63 are engaged with each other. A feeding hopper 64 is fixed at the bottom of the crushing box 61. One of the crushing shafts 62 and the separation rotating shaft 418 are connected by a synchronous chain two 65 through a sprocket four. One ends of the two crushing shafts 62 are respectively connected with transmission gears 66, and the two transmission gears 66 are engaged with each other. Support frames 67 are symmetrically fixed on both sides of the bottom of the loading box 421. A leveling roller 68 is rotatably connected between the two support frames 67. A soil scraping knife 69 is attached to the surface of the leveling roller 68, and the soil scraping knife 69 is fixed between the two support frames 67.

[0024] The working principle and usage process of the present invention: When it is necessary to reclaim and level farmland, first connect the tractor and the traction harrow body 1 through the traction frame 2. During operation, power is transmitted to the drive shaft 41 through the coupling 3. The drive shaft 41 drives the rotary tillage rotating shaft 42 and the rotating shaft 45 to rotate inside the traction harrow body 1 through a sprocket one and a transmission chain one 47. As the rotary tillage rotating shaft 42 rotates, the rotary tillage teeth 43 on its surface perform rotary tillage operations on the farmland soil, break up the compacted soil, make the soil loose, and at the same time turn out sundries such as stones and stumps buried deep underground, preparing for subsequent stone removal and separation work. Through the high-speed rotation of the rotary tillage teeth 43, the soil together with sundries such as stones and stumps can be thrown up and fall onto the filter stone mesh plate one 44. Due to the mesh design of the filter stone mesh plate one 44, smaller soil particles fall through the mesh holes, while sundries such as stones and stumps and larger soil clods will remain on the filter stone mesh plate one 44. Then, the rotating shaft 45 drives the spiral augers 46 on both sides to rotate, and the intercepted sundries such as stones and stumps and larger soil clods can be conveyed along the concave arc part of the filter stone mesh plate one 44 to the through groove opened in the middle of the filter stone mesh plate one 44. Finally, sundries such as stones and stumps and larger soil clods enter the area of the filter stone mesh plate two 48 through the through groove, realizing the effective separation of stones, stumps, and larger soil clods from soil particles, avoiding the impact of stones on subsequent farming and irrigation operations, preventing the possible harm to crop growth caused by pests and diseases carried by stumps, ensuring the purity of the soil, and improving the cultivability of the land.

[0025] It should be noted that: The side of the filter stone mesh plate one 44 close to the rotary tillage teeth 43 is an outward convex arc part, which helps to guide the soil and sundries towards the direction of the spiral auger 46. Smaller soil particles fall through the mesh holes of the filter stone mesh plate one 44, and larger soil clods will be conveyed together with sundries such as stones and stumps onto the filter stone mesh plate two 48.

[0026] Furthermore, the rotating shaft 45 drives the extrusion rotating shaft 49 to rotate in the traction rake body 1 through the sprocket wheel 2 and the transmission chain 2 420, thereby driving the worm part 410 on the surface of the extrusion rotating shaft 49 to rotate and mesh with the worm wheel ring 411, so that the worm wheel ring 411 drives the rotating disk 412 to rotate synchronously between the two sets of rotating ring frames 413. As the rotating disk 412 rotates, the eccentric levers 415 on both sides can be driven to make eccentric movements accordingly. The eccentric levers 415 are in the grooves at the top of the lifting frame 416. The sliding movement drives the lifting frame 416 and the squeezing plate 417 to make alternating up and down reciprocating motions, so that the squeezing plate 417 squeezes the larger soil blocks and impurities passing through the filter stone mesh plate 48, thereby further crushing the larger soil blocks, effectively crushing the large soil blocks that are difficult to handle, and breaking them into small particles suitable for cultivation, thereby improving the air permeability and water retention of the soil, and creating a good soil structure for the growth of crops. The squeezed and crushed soil blocks fall onto the filter stone mesh plate 48 and fall through the mesh holes of the filter stone mesh plate 48. , while the stones and roots which are difficult to be squeezed and crushed will remain on the stone filter screen plate 2 48. At the same time, the rotating shaft 45 drives the separation shaft 418 to rotate through the transmission chain 2 420. During the rotation process, the separation plate 419 on the surface of the separation shaft 418 will move the stones and roots which remain on the stone filter screen plate 2 48 along the concave arc portion of the stone filter screen plate 2 48 toward the loading box 421. The concave arc portion of the stone filter screen plate 2 48 helps to guide the impurities and stones to move to the stone discharge trough. A stone discharge trough is provided on one side of plate 2 48 close to loading box 421, through which stones and root residues enter loading box 421, thereby completing the removal of stones and root residues in the soil and ensuring that the stones and root residues can be efficiently cleaned, greatly reducing the burden of subsequent farmland maintenance and cultivation, avoiding their residues in the farmland, and reducing obstacles to subsequent farming operations. When performing operations such as sowing and irrigation, the equipment will not be damaged or the operation results will not be affected due to the remaining stones and root residues, thereby improving the safety and efficiency of farmland operations.

[0027] Furthermore, in order to ensure that the farmland is flat and loose, before the farmland is reclaimed, the operator turns the hand wheel 55 to drive the bidirectional screw rod 52 to rotate between the two sets of fixed plates 51. The threaded blocks 53 symmetrically threaded on both sides of the surface of the bidirectional screw rod 52 make relative or opposite linear motions along the bidirectional screw rod 52 under the restriction of the pulley track 54, thereby adjusting the positions of the two sets of support plates 56 and the loosening rake teeth 513 so that they are opposite to the driving path of the tractor wheels to adapt to the operation requirements of different widths. When it is necessary to loosen the soil compacted by the wheels, etc., as the rotary tillage shaft 42 rotates, the spline shafts 514 at both ends thereof rotate in the rotating frame 517, and transmit power to the loosening shaft 512 through the sprocket three and the synchronous chain one 515. The loosening shaft 512 rotates, driving the eccentric rotary rod 511 to rotate. The rotation of the eccentric rotating rod 511 causes the swing arm 59 to swing around the rotating rod 58, thereby driving the turning frame 510 and the loosening rake teeth 513 to turn up and down. During the up and down turning process, the loosening rake teeth 513 are inserted into the soil to pry up and break the compacted soil to restore the soil to a loose state. The soil compacted by wheels, etc. can be loosened, which can effectively break up the soil compaction, quickly restore the soil to a loose state, improve the soil air permeability and water permeability, create good conditions for the growth of crop roots, improve the survival rate and growth quality of crops, and fundamentally improve the production capacity of farmland.

[0028] It is worth noting that: in the process of adjusting the position of the support plate 56 and the loosening rake teeth 513, the loosening shaft 512 will move synchronously, and then drive the synchronous chain 1 515 and the push-pull plate 516 to move through the sprocket three fixed on its surface. Since the other end of the push-pull plate 516 is provided with a clearance hole compatible with the spline shaft 514, the movement of the push-pull plate 516 can drive the sprocket three connected to the spline shaft 514 with a key to move synchronously, ensuring that in the process of adjusting the position of the support plate 56 and the loosening rake teeth 513, the loosening shaft 512 and the spline shaft 514 play a stabilizing role in the power transmission process, ensuring the normal operation of the synchronous chain 1 515, and ensuring the smooth progress of the loosening operation.

[0029] Furthermore, the soil blocks processed by the extrusion plate 417 fall through the mesh holes of the second filter stone mesh plate 48 and enter the crushing box 61. The separation rotating shaft 418 drives one group of crushing shafts 62 to rotate through the fourth sprocket and the second synchronous chain 65. The transmission gears 66 at one end of the crushing shaft 62 mesh with the transmission gears 66 at one end of the other group of crushing shafts 62, causing the two groups of crushing shafts 62 to rotate in opposite directions. During the rotation, the crushing teeth 63 on the surfaces of the two groups of crushing shafts 62 that bite each other crush the soil entering the crushing box 61, further break the larger soil blocks, make the soil particles more uniform. Uniform soil particles contribute to better implantation and germination of crop seeds, promote uniform root growth, and lay a good foundation for the healthy growth of crops. The crushed soil has better air permeability and water permeability, which is conducive to the exchange of oxygen and water in the soil, meeting the requirements of crop growth for the soil environment. At the same time, uniform soil particles are also beneficial to the uniform distribution and absorption of fertilizers, improving the utilization efficiency of soil fertility, thereby enhancing the overall quality of the farmland and providing a strong guarantee for achieving the high-yield and high-quality goals of high-standard farmland. The crushed soil falls onto the surface of the farmland through the feeding hopper 64 at the bottom of the crushing box 61. The leveling roller 68 rotatably connected between the support frames 67 on both sides of the bottom of the loading box 421 rolls and levels the soil that has fallen to the ground under the drive of the traction harrow body 1, effectively eliminating the unevenness on the soil surface and making the soil surface smoother. The scraping knife 69 attached to the surface of the leveling roller 68 scrapes off the soil adhered to the surface of the leveling roller 68, preventing the soil from accumulating on the surface of the leveling roller 68 and affecting the leveling effect, ensuring that the soil can be evenly leveled and meeting the land leveling requirements for the reclamation of high-standard farmland.

[0030] It should be noted that: during continuous operation, without the cleaning of the scraping knife 69, the accumulation of soil on the surface of the leveling roller 68 will cause uneven rolling and affect the land leveling quality, ensuring that the leveling roller 68 is always in good working condition, continuously providing a reliable guarantee for soil leveling, and improving the reliability and operation quality of the equipment.

[0031] Finally, it should be noted that: the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
