Description

Technical Field

[0001] The present invention relates to the technical field of vegetable planting, and specifically, to a soil-turning device for vegetable planting. Background Art

[0002] Vegetable planting refers to the process of cultivating, propagating, and harvesting vegetable crops through artificial intervention and management in a specific land or facility environment to meet the food needs of humans. It is an important part of agricultural production, covering a complete production chain from seed selection, soil preparation, sowing, field management to final harvesting. Reasonable vegetable planting helps to conserve water and soil, improve soil structure, and promote ecological balance. Field management of vegetable planting requires regular intertillage and soil loosening, weed removal, and maintaining soil looseness and a good crop growth environment.

[0003] After retrieval, a Chinese patent application with the publication number CN119856604A discloses a soil-turning device for vegetable planting to prevent breakage, including a connecting rod and a frame at the rear side of a tractor. The frame is installed at the other end of the connecting rod, a driving shaft is installed on the frame, a tractor transmission wheel is installed in the middle of the driving shaft, several short arms are installed on the driving shaft, a soil-turning rod is hinged at the other end of the short arm, a plow blade for turning the soil is installed at the bottom end of the soil-turning rod, a connecting rod is installed on the handle of the plow, a piston block is installed on the connecting rod, a piston cavity is opened in the soil-turning rod, and then through the cooperation of the piston block and a spring, it is realized that during the working process of the soil-turning machine, when the plow blade encounters a hard soil block, it can be shortened in time, effectively playing a buffering effect, while reducing the wear of the plow blade tip, improving the working life of the soil-turning machine, and solving the problem that there are hard soil blocks with high hardness in some un-renovated land, which are likely to cause wear to the shovel blade. However, when this solution is actually used, there are still the following deficiencies: The above soil-breaking device effectively protects the plow blade by virtue of its buffering function. However, in the face of complex and changeable planting environments, the soil conditions of actual vegetable planting areas vary greatly, often accompanied by a large number of hard soil blocks and weed debris. When the soil-breaking device is put into operation, although the plow blade can smoothly cut into the soil and complete the soil-turning action by virtue of the buffering mechanism, due to the high hardness and large toughness of the hard blocks in the soil, it is difficult to completely break them only by the conventional soil-turning operation of the plow blade. These unbroken hard blocks are mixed in the turned soil, not only resulting in the non-compliance of soil looseness, affecting the sowing of subsequent vegetable seeds and the growth of roots, but also hindering the penetration of irrigation water and the uniform distribution of fertilizers.

[0004] Based on this, the present invention discloses a soil-turning device for vegetable planting. Summary of the Invention

[0015] 2.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides a soil-turning device for vegetable planting. Refer to Figures 1 - 10 As shown, it includes a shovel-type soil-turning body 11. A power take-off box 12 is arranged inside the shovel-type soil-turning body 11. An impurity removal box 13 is fixedly installed at the forward end of the shovel-type soil-turning body 11 through a support plate. An inclined panel is fixedly installed at the bottom of the feeding end of the impurity removal box 13. A soil-breaking frame 14 is fixedly installed at the tail end of the shovel-type soil-turning body 11. The input end of the power take-off box 12 is provided with a drive shaft 15. Two mounting brackets 16 are symmetrically and fixedly installed on the side surface of the shovel-type soil-turning body 11; Among them, protection boxes 21 are fixedly installed at both ends of the impurity removal box 13. Paddles 23 are arranged inside the two protection boxes 21. A linkage structure corresponding to the paddle 23 is arranged inside the protection box 21. A plurality of material dividing plates 41 distributed in a linear array are fixedly installed on the inner wall of the soil-breaking frame 14. Soil-breaking components are arranged on the bottom surfaces of the plurality of material dividing plates 41; The shovel-type soil-turning body 11 can be connected to the traction device through the mounting frame 16, and the power take-off box 12 is power-connected to the traction device through the drive shaft 15, so that the shovel-type soil-turning body 11 receives power input. The traction device can tow the shovel-type soil-turning body 11 to turn the soil in the vegetable planting field. During the operation of the shovel-type soil-turning body 11, the baffle 23 can be driven through the linkage structure, so that the two baffles 23 at both ends of the impurity removal box 13 can swing reciprocally to rake the soil blocks and weeds on the ground of the traveling route of the vegetable planting field into the impurity removal box 13 for collection. During the traveling of the shovel-type soil-turning body 11, the soil can be turned over by the soil-turning shovel plow, causing the soil to be lifted, thus achieving the soil-turning effect. For the lifted soil, it can enter the soil-breaking frame 14 and enter between the respective material distribution plates 41 under the action of the material distribution plate 41, and then the large soil blocks in the turned-up soil are broken by the soil-breaking assembly. The broken soil can return to the ground through the soil-breaking frame 14, ensuring that the large soil blocks can be fragmented and improving the soil-turning effect. The working principles and connection methods of the shovel-type soil-turning body 11 and the power take-off box 12 are all existing mature technologies and will not be elaborated here.

[0022] See Figure 3 、 Figure 4 As shown in, the linkage structure includes a rotating shaft 22 rotatably installed between the inner bottom surface and the inner top surface of the protection box 21. The baffle 23 is fixedly sleeved on the outer wall of the rotating shaft 22. The baffle 23 is bent. A torsion spring 24 is sleeved on the top end of the rotating shaft 22, and the two ends of the torsion spring 24 are fixedly connected to the rotating shaft 22 and the protection box 21 respectively. A driven bevel gear 25 is fixedly sleeved on the outer wall of the rotating shaft 22. A driving half bevel gear 26 meshing with the driven bevel gear 25 is rotatably installed on the inner wall of the protection box 21. An opening 27 corresponding to the baffle 23 is formed on the side surface of the protection box 21. One end of the impurity removal box 13 close to the shovel-type soil-turning body 11 is fixedly installed with a mounting box 31, and a soil-loosening structure is arranged on the mounting box 31; During the operation of the shovel-type soil-turning mechanism 11, as the impurity removal box 13 moves, the driving bevel gear 26 can be driven. When the conical teeth on the driving bevel gear 26 mesh with the conical teeth on the driven bevel gear 25, the driven bevel gear 25, the rotating shaft 22, and the baffle 23 can be driven to rotate, causing the two baffles 23 to rotate in the expanding direction. As the conical teeth on the driving bevel gear 26 separate from the conical teeth on the driven bevel gear 25 during the rotation of the driving bevel gear 26, under the action of the torsion spring 24, the rotating shaft 22 and the baffle 23 can reverse, thereby realizing the reciprocating drive of the two baffles 23, enabling the two baffles 23 to push the soil clods and weeds on the moving route of the impurity removal box 13 to the front of the impurity removal box 13. As the impurity removal box 13 moves, the soil clods and weeds can be shoveled into the interior of the impurity removal box 13 through the inclined panel for storage, ensuring that the stones that may exist on the moving route of the shovel-type soil-turning mechanism 11 can be removed, avoiding damage to the soil-turning shovel plow; through the automatic impurity removal mechanism of mechanical transmission, hard objects and sundries in the soil can be effectively removed, avoiding wear or damage caused by the direct impact of the soil-turning shovel plow on foreign objects such as stones. This not only extends the service life of the equipment but also ensures the continuity and safety of the soil-turning operation, reduces the frequency of shutdown maintenance caused by foreign object jams, improves the operation efficiency, and reduces the equipment loss cost.

[0023] See Figure 5 As shown, the soil loosening structure includes a crankshaft 32 rotatably installed on the inner wall of the installation box 31. Both ends of the crankshaft 32 pass through the installation box 31 and are fixedly installed with runner wheels 33. The crankshaft 32 is connected to the driving bevel gear 26 through a driven wheel and a synchronous belt. The outer wall of the runner wheel 33 is provided with anti-slip lines. A plurality of through openings 34 corresponding to the crankshaft 32 are linearly and arrayedly arranged on the bottom surface of the installation box 31. A soil loosening rod 35 is slidably installed on the inner wall of the through opening 34. The bottom end of the soil loosening rod 35 is conical. The top end of the soil loosening rod 35 is hinged with a connecting rod 36. A collar 37 corresponding to the connecting rod 36 is rotatably sleeved on the outer wall of the crankshaft 32. The top end of the connecting rod 36 is fixedly connected to the outer wall of the collar 37; When the impurity removal box 13 is moving, the two runner wheels 33 on its side can contact the ground and rotate. When the runner wheels 33 rotate, the crankshaft 32 can be driven to rotate. The soil loosening rod 35 slides in the through opening 34 and is connected to the crankshaft 32 through the connecting rod 36 and the collar 37. Therefore, when the crankshaft 32 rotates, the soil loosening rod 35 can be driven through the collar 37 and the connecting rod 36, enabling the soil loosening rod 35 to reciprocally slide along the through opening 34, so that the soil loosening rod 35 can reciprocally insert into the ground on the moving route of the impurity removal box 13, playing a role in pre-loosening the soil, so as to facilitate the subsequent rapid turning of the soil by the shovel-type soil-turning mechanism 11; through the physical action of mechanical linkage, hard soil clods are broken in advance and the compacted soil layer is loosened, reducing the resistance of the subsequent soil-turning operation, enabling the shovel-type soil-turning mechanism 11 to turn the soil more easily, reducing the equipment operation energy consumption and mechanical wear, and at the same time improving the soil-turning efficiency and shortening the operation time.

[0024] See Figures 6 - 8 As shown, the soil-breaking assembly includes two extrusion plates 42 symmetrically and slidably mounted on the bottom surface of the material distribution plate 41. The extrusion plates 42 are L-shaped, and the bottom surface of the extrusion plates 42 is flush with the bottom surface of the soil-breaking frame 14. Two return springs 43 are symmetrically and fixedly mounted between the opposite side surfaces of the two extrusion plates 42. A shaft rod 44 is rotatably mounted on the inner wall of the soil-breaking frame 14 between the two extrusion plates 42. Two dial blocks 45 are symmetrically and fixedly sleeved on the outer wall of the shaft rod 44. A transmission shaft 46 is provided between the end of one of the several shaft rods 44 corresponding to the transfer case 12 and the transfer case 12, and both ends of the transmission shaft 46 are connected to the shaft rod 44 and the transfer case 12 through universal joints. A tail box 51 is fixedly mounted on the side surface of the soil-breaking frame 14. The ends of several shaft rods 44 all pass through the side surface of the soil-breaking frame 14 and are located inside the tail box 51. The ends of several shaft rods 44 located inside the tail box 51 are connected by transmission wheels and belts. Several groups of soil-leveling assemblies corresponding to the shaft rods 44 are arranged inside the tail box 51; The soil turned over by the shovel-type soil-turning machine body 11 can be lifted, and as the soil-breaking frame 14 moves, the soil can enter the soil-breaking frame 14. During the operation of the transfer case 12, the shaft rod 44 can be driven to rotate through the universal joint and the transmission shaft 46. Several shaft rods 44 are connected by transmission wheels and belts, so synchronous rotation can be achieved. During the rotation of the shaft rod 44, the two dial blocks 45 can be driven. During the rotation of the two dial blocks 45, the extrusion plates 42 can be pushed, so that the two extrusion plates 42 can slide in the direction away from each other. During the sliding of the extrusion plates 42, the soil can be extruded by pressure, so as to realize the crushing of large soil blocks and improve the soil-turning effect. When the dial block 45 rotates to separate from the extrusion plate 42, under the action of the return spring 43, the two extrusion plates 42 can slide in the direction close to each other to reset, so as to realize the reciprocating drive of the extrusion plates 42 and thus perform the extrusion action; through the mechanical transmission extrusion and crushing mechanism, the caked soil remaining after traditional soil turning is further refined, effectively solving the problem of soil hard lumps, improving the soil looseness and uniformity, and creating better soil conditions for subsequent sowing, irrigation and other links.

[0025] See Figure 2 、 Figure 9 、 Figure 10As shown in the figure, the soil leveling component includes a driving half gear 52 fixedly installed at the end of the shaft rod 44. A sliding rack 53 meshing with the driving half gear 52 is slidably installed on the inner bottom surface of the tail box 51. A vertical plate 54 corresponding to the sliding rack 53 is fixedly installed on the inner bottom surface of the tail box 51. A support spring 55 is fixedly installed between the vertical plate 54 and the sliding rack 53. A guiding port 58 corresponding to the sliding rack 53 is formed on the side surface of the tail box 51. A guide rod 59 is fixedly installed on the side surface of the sliding rack 53. The end of the guide rod 59 passes through the guiding port 58 and is fixedly installed with a sliding plate 56. A plurality of comb teeth 57 distributed in a linear array are fixedly installed on the bottom surface of the sliding plate 56. The comb teeth 57 are in a hooked shape, and the horizontal position of the bottom end of the comb teeth 57 is below the horizontal position of the bottom surface of the soil breaking frame 14. During the rotation of the shaft rod 44, the driving half gear 52 can be driven to rotate synchronously. When the teeth on the driving half gear 52 contact the teeth on the sliding rack 53 during rotation, the sliding rack 53 can be driven to slide. When the teeth on the driving half gear 52 are separated from the teeth on the sliding rack 53, the sliding rack 53 can be reset under the elastic force of the support spring 55. In this way, the reciprocating drive of the sliding rack 53 is realized, so that the sliding rack 53 can drive the sliding plate 56 and the comb teeth 57 to slide reciprocally along the guiding port 58. The comb teeth 57 can be inserted into the ground, playing a role in leveling the soil after soil turning, ensuring that the distribution of the soil after soil turning is more uniform; through the transmission mechanism of the gear and rack, the fine finishing of the soil after ploughing is realized, effectively eliminating the problems of soil accumulation or uneven distribution, making the soil surface flat and the particles uniform, providing guarantee for the depth consistency and emergence rate of subsequent sowing, and at the same time reducing the workload of manual secondary land preparation and improving the standardization and normalization degree of planting operations.

[0026] The working principle of the present invention is as follows: During use, first, the spade-type soil-turning body 11 can be connected to the traction device through the mounting frame 16, and the power take-off box 12 and the traction device can be connected by the drive shaft 15 to input power to the spade-type soil-turning body 11. The traction device can tow the spade-type soil-turning body 11 to turn the soil in the vegetable planting field. During the operation of the spade-type soil-turning body 11, the baffle 23 can be driven through the linkage structure, so that the two baffles 23 at both ends of the impurity removal box 13 can swing reciprocally to push the soil blocks and weeds on the ground along the traveling route of the vegetable planting field into the impurity removal box 13 for collection. During the traveling of the spade-type soil-turning body 11, the soil can be turned by the soil-turning spade plow, causing the soil to be lifted, thus achieving the soil-turning effect. For the lifted soil, it can enter the soil-breaking frame 14 and enter between the respective material distribution plates 41 under the action of the material distribution plate 41, and then the large soil blocks in the turned-up soil can be broken by the soil-breaking component. The broken soil can return to the ground through the soil-breaking frame 14, ensuring that the large soil blocks can be fragmented and improving the soil-turning effect. The working principles and connection methods of the spade-type soil-turning body 11 and the power take-off box 12 are all existing mature technologies and will not be elaborated here; Specifically, during the operation of the spade-type soil-turning body 11, as the impurity removal box 13 moves, the driving bevel gear 26 can be driven. When the conical teeth on the driving bevel gear 26 mesh with the conical teeth on the driven bevel gear 25, it can drive the driven bevel gear 25, the rotating shaft 22, and the baffle 23 to rotate, causing the two baffles 23 to rotate in the expanding direction. As the conical teeth on the driving bevel gear 26 separate from the conical teeth on the driven bevel gear 25 during the rotation of the driving bevel gear 26, under the action of the torsion spring 24, the rotating shaft 22 and the baffle 23 can reverse, thereby realizing the reciprocating drive of the two baffles 23, enabling the two baffles 23 to push the soil blocks and weeds on the traveling route of the impurity removal box 13 to the front of the impurity removal box 13. As the impurity removal box 13 moves, the soil blocks and weeds can be shoveled into the interior of the impurity removal box 13 through the inclined panel for storage, ensuring that the stones that may exist on the traveling route of the spade-type soil-turning body 11 can be removed to avoid damage to the soil-turning spade plow; when the impurity removal box 13 travels, the two runners 33 on its side can contact the ground and rotate. When the runners 33 rotate, they can drive the crankshaft 32 to rotate. The soil loosening rod 35 slides in the through-hole 34 and is connected to the crankshaft 32 through the connecting rod 36 and the collar 37. Therefore, when the crankshaft 32 rotates, it can drive the soil loosening rod 35 through the collar 37 and the connecting rod 36, enabling the soil loosening rod 35 to slide reciprocally along the through-hole 34, so that the soil loosening rod 35 can be reciprocally inserted into the ground along the traveling route of the impurity removal box 13 to pre-loosen the soil, facilitating the subsequent rapid turning of the soil by the spade-type soil-turning body 11; The soil turned over by the shovel-type soil-turning mechanism 11 can be lifted, and as the soil-breaking frame 14 moves, the soil can enter the soil-breaking frame 14. During the operation of the transfer case 12, the shaft rod 44 can be driven to rotate through the universal joint and the transmission shaft 46. The plurality of shaft rods 44 are connected by transmission wheels and belts, so synchronous rotation can be achieved. During the rotation of the shaft rod 44, the two dial blocks 45 can be driven. During the rotation of the two dial blocks 45, the extrusion plate 42 can be pushed, so that the two extrusion plates 42 can slide in the direction away from each other. During the sliding of the extrusion plate 42, the soil can be extruded by pressure, thereby realizing the crushing of large soil blocks and improving the soil-turning effect. When the dial block 45 rotates to separate from the extrusion plate 42, under the action of the return spring 43, the two extrusion plates 42 can slide in the direction close to each other to reset, thereby realizing the reciprocating drive of the extrusion plate 42 and thus performing the extrusion action; during the rotation of the shaft rod 44, the driving half gear 52 can be driven to rotate synchronously. When the teeth on the driving half gear 52 contact the teeth on the sliding rack 53 during rotation, the sliding rack 53 can be driven to slide. When the teeth on it separate from the teeth on the sliding rack 53, under the elastic force of the support spring 55, the sliding rack 53 can be reset, thereby realizing the reciprocating drive of the sliding rack 53, so that the sliding rack 53 can drive the slide plate 56 and the comb teeth 57 to slide reciprocally along the guide port 58. The comb teeth 57 can be inserted into the ground to play a role in leveling the soil after soil-turning, ensuring that the distribution of the soil after soil-turning is more uniform.
