Description

Technical Field

[0001] This utility model relates to the field of field ridge compaction technology, specifically to a field ridge compaction device for agricultural planting. Background Technology

[0002] In agricultural land, each field is separated by field ridges. In the past, these ridges were messy and disorganized. As more and more farmland is contracted out to individuals, it is necessary to repair these messy ridges during large-scale planting to facilitate unified planning and crop planting. In view of this, land compaction devices have emerged. Land compaction devices are machines that use the gravity of mechanical equipment to deform and compact the ground, making the ground flat and compacted, reducing the amount of manual work required for land preparation and compaction.

[0003] However, existing land compaction devices have certain problems. A search revealed, for example, a Chinese patent application with publication number CN207854434U discloses a field ridge trimming and compaction machine. This machine uses an internal combustion engine to drive an eccentric vibrator, generating a powerful impact force to compact the field ridges. This solidifies the soil on the ridges, preventing them from collapsing due to loose soil or scattering soil when wet. During the compaction process, the machine can also trim the sides of the ridges with an electric saw blade, ensuring a consistent width and neat, uniform appearance. The machine is highly effective.

[0004] However, in actual use, the chainsaw blade is prone to chipping when it comes into contact with hard objects such as rocks. Its fixing structure requires disassembling the locking nut and the outer shell to replace it, which is cumbersome and time-consuming. At the same time, the chainsaw blade is exposed without any protective device. In the field ridge environment with many weeds and rocks, it is easy to get stuck by foreign objects, causing the machine to stop. There is even a safety hazard of the saw blade breaking and flying. Utility Model Content

[0005] The purpose of this invention is to provide a land separation and compaction device for agricultural planting. Through the shaping plate, foreign objects can be easily removed, solving the problem of machine shutdown caused by foreign objects getting stuck.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for compacting and separating field ridges for agricultural planting, comprising a device body, wherein the device body includes a handcart, and extension blocks are fixedly connected to the center of both ends of the handcart; A fixing rod is fixedly connected to the center of the front side of the extension block; The front end of the extension block is provided with a sliding groove, and a connecting mechanism is provided inside the sliding groove; The handcart is equipped with a first compaction mechanism and a third compaction mechanism at both ends. The first compaction mechanism is used to compact the land, and the third compaction mechanism is used to divide the land.

[0007] Preferably, a compaction block is fixedly connected to the center of the bottom of the wheelbarrow for preliminary compaction of the land.

[0008] Preferably, a configuration frame is fixedly connected to the top center of the handcart, and a stud is fixedly connected to the bottom center of the configuration frame. A configuration block is sleeved on the surface of the stud. By setting the configuration block inside the configuration frame, the impact force of the compaction block on the soil can be adjusted, preventing ineffective compaction due to insufficient pressure. A sealing cap is snapped onto the top of the configuration frame to reduce the erosion of the configuration block by mud and water and to protect the configuration block.

[0009] Preferably, the connecting mechanism includes a fixed sleeve, and a sliding block is fixedly connected to the top of the outer surface of the fixed sleeve. The sliding block is slidably connected inside the groove, which allows the fixed rod to be interference-fitted into the fixed sleeve, thereby enabling the quick disassembly of the connecting mechanism.

[0010] Preferably, the top of the extension block is fixedly connected to mounting plates located on both sides of the slide groove. The mounting plates and the sliding plates are connected by plug pins to achieve longitudinal fixation between the connecting mechanism and the main body of the device, making the connection between the connecting mechanism and the main body of the device more stable.

[0011] Preferably, the first compaction mechanism includes a first compaction frame, and a compaction roller is rotatably connected inside the first compaction frame via a bearing for final compaction of the soil.

[0012] Preferably, the third compaction mechanism includes a third compaction frame, a third shaping plate is symmetrically fixedly connected to the bottom of the outer wall of the third compaction frame, a plow is fixedly connected to the top of the outer wall of the third compaction frame, the plow is used to break up the land to facilitate subsequent leveling, and a bulldozer plate is symmetrically fixedly connected to the outer wall of the plow, the bulldozer plate can push the soil here, providing wheels and walking space for the wheelbarrow, making it convenient to use.

[0013] Preferably, the front end of the handcart is further provided with a second compaction mechanism, the second compaction mechanism including a second compaction frame, a first shaping plate symmetrically fixedly connected to the bottom of the outer wall of the second compaction frame, and a second shaping plate located above the first shaping plate fixedly connected to the outer wall of the second compaction frame, for leveling the top and sides of the land.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model discloses a land separation and compaction device for agricultural planting. By setting up a first compaction mechanism and a third compaction mechanism, it can simultaneously complete land compaction and leveling operations while performing land separation operations, forming an integrated "separation-compactment-leveling" operation process, effectively improving the overall operating efficiency of the hand-push device. The leveling function is achieved through a shaping plate, which not only smooths the surface of the compacted land but also, in conjunction with an arc-shaped guide plate, actively guides and removes foreign objects such as stones and weed roots to both sides during operation, preventing foreign objects from being drawn into the equipment and causing jamming and shutdown. 2. This utility model provides a land dividing and compaction device for agricultural planting. By setting a connecting mechanism, the first compaction mechanism and the third compaction mechanism can be stably fixed to the surface of the main body of the device. The interference fit between the fixing rod and the fixing sleeve can eliminate radial gaps and avoid vibration displacement. At the same time, the mounting plate and the sliding plate are longitudinally fixed by the insertion and removal pins, which produces a double locking effect and makes the connection more stable.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings. Example 1:

[0019] This utility model provides, for example Figure 1-7 The device shown is a field ridge compaction device for agricultural planting, including a main body 1. The main body 1 includes a handcart 11, and extension blocks 14 are fixedly connected to the center of both ends of the handcart 11. A fixing rod 15 is fixedly connected to the center of the front side of the extension block 14; The front end of the extension block 14 is provided with a slide groove 16, and the interior of the slide groove 16 is provided with a connecting mechanism 7; The handcart 11 is equipped with a first compaction mechanism 2 and a third compaction mechanism 4 at both ends. The first compaction mechanism 2 is used to compact the land, and the third compaction mechanism 4 is used to divide the land.

[0020] In order to compact the land, such as Figure 1 , Figure 3 , Figure 8 As shown, a pressure block 6 is fixedly connected to the bottom center of the handcart 11. The top of the pressure block 6 is rigidly connected to the bottom of the configuration frame 12 through four Φ8mm positioning pins. The outer surface of the stud 13 inside the configuration frame 12 is provided with M16×2 threads. The center of the configuration block 8 is provided with an opening, which is fitted onto the surface of the stud 13. A nut is provided on the surface of the stud 13. After a suitable number of configuration blocks 8 are fitted, the nuts are fitted onto the stud 13 and tightened. Then, the sealing cover 5 is placed on the top of the configuration frame 12. The configuration blocks 8 are made of cast iron (single block weight 1-3kg, 2-3 blocks can be stacked). Their gravity is transmitted to the pressure block 6 through the stud 13 and the configuration frame 12 to achieve impact force adjustment.

[0021] To ensure the stable installation of the connecting mechanism 7 onto the surface of the device body 1, such as Figure 2 , Figure 4-5 As shown, the connecting mechanism 7 includes a fixed sleeve 71, and the fixed rod 15 is interference-fitted into the fixed sleeve 71, thus eliminating radial clearance and preventing vibration displacement.

[0022] A sliding block 72 is fixedly connected to the top of the outer surface of the fixed sleeve 71. The sliding block 72 is fitted and slidably connected inside the slide groove 16. The sliding block 72 moves only along the length direction to limit the fixed sleeve 71 and reduce the operating resistance.

[0023] The top of the extension block 14 is fixedly connected to the mounting plates 17 located on both sides of the slide groove 16. The mounting plates 17 and the sliding block 72 are longitudinally fixed by a plug-in pin. One end of the plug-in pin is provided with a spring-type anti-disengagement buckle. After being inserted into the corresponding pin hole of the mounting plate 17 and the sliding block 72, it automatically locks. Together with the aforementioned fixing rod 15, it is interference-fitted into the fixing sleeve 71 to produce a double locking effect, making the connection more stable.

[0024] To make the soil compaction more stable, such as Figure 6 As shown, the first compaction mechanism 2 includes a first compaction frame 21, in which a fixed sleeve 71 is fixedly connected to the first compaction frame 21. The first compaction frame 21 is an "U" shape with the opening facing downwards. The bottom two sides of the first compaction frame 21 are in contact with the two sides of the separated land, which is used to limit the movement of the handcart 11. The interior of the first compaction frame 21 is rotatably connected to a compaction roller 22 through a bearing. The bottom of the compaction roller 22 is in contact with the top of the land. After the compaction block 6 performs the initial compaction of the land, the compaction roller 22 can compact the land again to improve the compaction effect.

[0025] To separate the land, the third compaction mechanism 4 includes a third compaction frame 41, which has the same shape as the first compaction frame 21. The bottom of the third compaction frame 41 contacts the top of the land. A plow 43 is fixedly connected to the top of the outer wall of the third compaction frame 41 to turn over weeds and stones in the land, making it easier to separate the land. A bulldozer plate 44 is symmetrically fixedly connected to the outer wall of the plow 43. The bulldozer plate 44 is similar to a scraper, with the blades of the scraper set in a vertical direction. The bulldozer plate 44 can push the soil to move and separate the land.

[0026] The bottom of the outer wall of the third compaction frame 41 is symmetrically fixed with a third shaping plate 42, which is used to level the land.

[0027] It is worth noting that an arc-shaped guide plate is fixedly connected to the top of the outer wall of the third compaction frame 41 and between the plow 43 and the bulldozer blade 44. This structure adopts a concave arc design and is made of 1.5mm thick 65Mn spring steel. It is rigidly connected to the third compaction frame 41 by bolts. The bottom edge of the arc-shaped guide plate 45 is flush with the front end of the cutting edge of the bulldozer blade 44. During operation, the stones turned up by the plow 43 are first guided to the center of the cutting edge of the bulldozer blade 44, forming a pre-treatment process of "turning up-guiding-cutting".

[0028] It is worth noting that the bulldozer blade 44 adopts a "base steel + hard alloy inlay" design. The scraper base is made of 65Mn spring steel (2mm thick) to ensure elasticity, and the cutting edge is inlaid with 3-5mm thick tungsten cobalt hard alloy. The alloy and the base are firmly bonded through high-frequency welding. The cutting edge is designed as an "acute wedge" (30° angle), which reduces cutting resistance by using the wedge effect. It can cut pebbles and gravel with a diameter ≤20mm. During operation, the stone is accurately guided into the cutting area of ​​the cutting edge by the propulsion force of the handcart 11 and the guiding effect of the arc-shaped guide plate, avoiding slippage and deviation. At this time, the wheels of the handcart 11 can move within the space pushed by the bulldozer blade 44, which is convenient to use. Example 2:

[0029] This utility model provides, for example Figure 2-6 and Figure 8-9 The device shown is a field ridge compaction device for agricultural planting, including a device body 1. The device body 1 includes a handcart 11. Extension blocks 14 are fixedly connected to the center of both ends of the handcart 11. The front end of the extension block 14 is provided with a chute 16. The interior of the chute 16 is provided with a connecting mechanism 7. The handcart 11 is equipped with a first compaction mechanism 2 and a second compaction mechanism 3 at both ends. The first compaction mechanism 2 is used to compact the land, and the second compaction mechanism 3 is used to level the land.

[0030] The structure of the main body 1, the first compaction mechanism 2, and the connecting mechanism 7 is the same as that in Embodiment 1, and will not be described in detail again.

[0031] It is worth noting that Embodiment 1 is used when the land is not divided, and it can level and compact the land while dividing it. Considering that the land may not be flat after compaction, a second compaction mechanism 3 needs to be connected to the front end of the handcart 11 through a connecting mechanism 7, such as... Figure 9 As shown, the second compaction mechanism 3 includes a second compaction frame 31, the shape of which is the same as that of the third compaction frame 41. A first shaping plate 32 is symmetrically fixedly connected to the bottom of the outer wall of the second compaction frame 31 for leveling the side of the land. A second shaping plate 33 located above the first shaping plate 32 is fixedly connected to the outer wall of the second compaction frame 31 for leveling the top of the land. The shapes of the first shaping plate 32 and the second shaping plate 33 are the same as those of the third shaping plate 42.
