Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, and in particular to a ridging and mulching machine. Background Technology

[0002] Ridging and mulching is an agricultural production technique that increases soil temperature, maintains soil moisture, and inhibits weed growth through ridge-making and mulching operations, thereby increasing crop yield and achieving sustainable agricultural development. In cold regions of northern and southern China, mulching in spring can raise soil temperature by 2-4℃, increase accumulated temperature during crop growth, promote early seedling emergence, and extend crop growth time. Mulching cuts off the moisture exchange channel between soil and near-surface air. Due to the diurnal temperature difference, water evaporating from the soil condenses on the film. As humidity increases, water droplets drip into the soil surface under gravity, creating a water cycle from the film to the topsoil. This effectively inhibits soil moisture evaporation, increases the surface soil moisture content, and promotes the transfer of water from below the topsoil to the topsoil, increasing topsoil moisture by 1%-4%. Mulching reduces weed photosynthesis, thus inhibiting weed growth. Ridging improves soil structure, promotes root growth, and enhances the crop's ability to absorb water and nutrients. Mulching prevents vertical evaporation of soil moisture and, due to the heat accumulated inside the film, increases surface soil moisture accumulation, forming water vapor and thus inhibiting salt rise.

[0003] Chinese patent document CN218163505U discloses a ridging and mulching machine, in which a film roll is rotatably installed between two sets of extended perforated plates. The film roll is stored through the film roll. However, in this solution, the film needs to be wound around the film roll to form a rolled film roll, which is cumbersome to operate. If the hollow rolled film roll is directly put on a fixed shaft and the film roll is allowed to rotate on the fixed shaft, the film roll is easy to sway left and right on the fixed shaft, which makes the film position easy to shift during mulching and affects the mulching quality. In any case, it is difficult to adapt to mulch film of different widths, resulting in a narrow range of application and low flexibility of ridging and mulching machine. Utility Model Content

[0073] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, this description is exemplary and does not limit the present invention to the specific embodiments described herein.

[0074] Figure 1-3 This is a schematic diagram illustrating the structure of a ridging and mulching machine according to an embodiment of the present invention.

[0075] like Figure 1-3As shown, the ridging and mulching machine includes a side support frame 1 and a transverse support frame 2. The transverse support frame 2 is connected to the side support frames 1 on both sides. The bottom of the side support frame 1 is equipped with multiple wheels 13. The transverse support frame 2 includes multiple support bars, two push-pull columns located on both sides, and a mechanical connection end group. The two ends of the support bars are respectively connected to the two side support frames 1. The push-pull columns are connected to the top of the two side support frames 1. The mechanical connection end group is connected to the top of the side support frame 1 and can be connected to an agricultural planting vehicle.

[0076] When in use, the ridging and mulching machine can be manually moved using the push-pull column, or it can be connected to an agricultural planting vehicle via the mechanical connection end assembly, allowing the agricultural planting vehicle to move the ridging and mulching machine.

[0077] like Figure 4-9 As shown, the feeding unit includes a clamping assembly 3 and an adjusting assembly 4. The feeding unit is used to install and disassemble rolled mulch film for supplying mulch film to the ridging and mulching machine. Clamping assemblies 3 are connected to opposite sides of the two side support frames 1, and adjusting assemblies 4 are connected to opposite sides of the two clamping assemblies 3. A conveying assembly 5 is provided on one side of the clamping assembly 3 and the adjusting assembly 4. One end of the conveying assembly 5 is connected to one side support frame 1, and the other end is rotatably connected to the other side support frame 1. The clamping assembly 3 is used to adjust the position of the adjusting assembly 4, the adjusting assembly 4 is used to install and disassemble rolled mulch film, and the conveying assembly 5 is used to convey and feed the mulch film. A first regulating assembly 10 is also included. The first control component 10 and the second control component 11 are sequentially arranged on the side of the conveying component 5 away from the clamping component 3. The bottom of the first control component 10 is connected to two symmetrically distributed pressing film components 8, and the bottom of the second control component 11 is connected to two symmetrically distributed covering soil components 9. The first control component 10 and the second control component 11 are connected by a drive coupling component 12. The first control component 10 is used to adjust the lateral position and height of the two pressing film components 8, and the second control component 11 is used to adjust the position and height of the two covering soil components 9. The pressing film components 8 are used to press and spread the laid mulch film, and the covering soil components 9 are used to cover the mulch film with soil on both sides.

[0078] One side of the soil covering component 9 has an arc-shaped structure, and the other side of the soil covering component 9 has a pointed structure, which makes it easy to turn over the soil and form a ridge structure in the field.

[0079] In this technical solution, the position of the clamping component 3 can be adjusted by using the adjusting component 4, thereby adjusting the distance between the two clamping components 3, so that film rolls of different lengths can be installed and fixed, and film rolls of different lengths can be placed in the center position of the ridging and mulching machine, which facilitates the mulching operation and makes the ridging and mulching machine more widely used and more flexible.

[0080] Meanwhile, the force clamping component 3 can stably clamp the mulch film roll, so that the mulch film roll will not sway from side to side when the mulch film is fed, so that the mulch film will not shift or change position when it is laid, making the mulch film straighter and improving the mulch film quality.

[0081] The overall operation of the ridging and mulching machine is as follows: the clamping component 3 is used to fix the mulch film roll, and then the conveying component 5 is used to convey and guide the mulch film. As the ridging and mulching machine moves, the mulch film can cover the land. Then, the pressing component 8 presses the mulch film to prevent it from being blown away by the wind. Then, the soil covering component 9 is used to cover the soil on both sides of the mulch film, and the ridging operation is completed at the same time. Thus, the overall ridging and mulching operation can be completed.

[0082] The clamping assembly 3 includes a mounting plate 31, a fixed shaft 32 is connected to one side of the mounting plate 31, and a rotating sleeve 33 is rotatably connected to the surface of the fixed shaft 32.

[0083] The rotating sleeve 33 has an "I" shaped cross-section, and an annular airbag 34 is connected to the middle of the outer surface of the rotating sleeve 33.

[0084] In this technical solution, the clamping component 3 can be used to clamp and fix the mulch film roll.

[0085] The annular airbag 34 is connected to the inflation pump assembly, which is connected to the side support frame 1.

[0086] In use, the annular airbag 34 is inflated and deflated using an air pump unit.

[0087] It is worth noting that, such as Figure 7-8 As shown, when storing plastic film, it is wound around a hollow cylinder to form a plastic film roll.

[0088] In use, the adjusting components 4 on both sides drive the mounting plate 31, the fixed shaft 32, the rotating sleeve 33 and the annular airbag 34 to move respectively, so that the rotating sleeve 33 and the annular airbag 34 are in the center hole of the mulch film roll. Then, the air pump group is used to inflate the annular airbag 34, so that the annular airbag 34 expands and fits tightly against the inner wall of the mulch film roll, thus fixing the mulch film roll.

[0089] During disassembly, use the opposite method to move the annular airbag 34 away from the mulch roll, at which point the hollow cylinder can be removed.

[0090] The adjustable distance assembly 4 includes a fixed side plate 41, a fixed frame 42, and an adjustable distance bidirectional screw 43. The fixed side plate 41 and the fixed frame 42 are both connected to one side of the side support frame 1.

[0091] One end of the adjustable pitch bidirectional screw 43 is rotatably connected to the fixed side plate 41, and the other end of the adjustable pitch bidirectional screw 43 is rotatably connected to one side of the fixed frame shell 42. The end of the adjustable pitch bidirectional screw 43 extending into the fixed frame shell 42 is connected to the drive transmission component 6.

[0092] The adjustable bidirectional screw 43 has two left-right symmetrically distributed adjustable plates 44 threadedly connected to its surface, and a connecting strip 45 is provided between the adjustable plates 44 and the mounting plate 31.

[0093] Both ends of the connecting strip 45 are rotatably connected to rotating frames 46. Two of the rotating frames 46 on one side are respectively connected to one side of the adjusting plate 44, and two of the rotating frames 46 on the other side are connected to one side of the mounting plate 31.

[0094] In this technical solution, the position of the clamping component 3 can be adjusted using the adjusting component 4.

[0095] Multiple anti-deviation rails 47 are connected between the fixed side plate 41 and the fixed frame shell 42, and the surface of the anti-deviation rails 47 is slidably connected to the adjusting plate 44.

[0096] The rotating frame 46 is composed of a central column and side plates. Both ends of the central column are connected to side plates. The surface of the central column is rotatably connected to the connecting strip 45. The side plates are respectively connected to one side of the corresponding adjusting plate 44 or the mounting plate 31.

[0097] The rotating frame 46 allows the connecting bar 45 to rotate as the adjusting plate 44 moves. In use, the adjusting plate 44 rotates around the central column.

[0098] In this technical solution, the movement trajectory of the adjusting plate 44 can be limited by the anti-deviation track 47.

[0099] In use, the drive transmission component 6 drives the adjusting bidirectional screw 43 to rotate, thereby driving the adjusting plates 44 on both sides to move in the same direction or opposite direction along the anti-deviation track 47. At this time, under the action of the rotating frame 46, the connecting strips 45 on both sides can rotate, thereby driving the mounting plate 31 and other structures to move and adjust the position of the mounting plate 31 and other structures.

[0100] The drive assembly 6 includes a bidirectional drive source 61, which is connected to the inner cavity of the drive protection frame 14. The two sides of the drive protection frame 14 are respectively connected to one side of the fixed frame 42. Both output ends of the bidirectional drive source 61 are connected to a drive shaft 62. The end of the drive shaft 62 away from the bidirectional drive source 61 is connected to a bevel gear 63.

[0101] The bevel gear 63 is meshed with a bevel gear 64 on its side, and one side of the bevel gear 64 is connected to one end of the adjustable bidirectional screw 43.

[0102] In this technical solution, the drive transmission component 6 can simultaneously provide driving force to the pitch adjustment components 4 on both sides, so that the pitch adjustment components 4 on both sides can operate at the same time, which can save energy.

[0103] In use, the bidirectional drive source 61 drives the transmission shafts 62 on both sides to rotate, which in turn drives the first bevel gear 63 to rotate, and then drives the second bevel gear 64 to rotate. When the second bevel gear 64 on both sides rotates, it can drive the adjustable bidirectional screws 43 on both sides to rotate.

[0104] The conveying assembly 5 includes two conveying shafts 51 distributed vertically. One end of each conveying shaft 51 is rotatably connected to one side of one of the side support frames 1. The other end of each conveying shaft 51 is connected to a rotating gear 52, and the two rotating gears 52 are meshed together.

[0105] Both of the rotating gears 52 are disposed in the inner cavity of the conveying protective frame 15. The conveying protective frame 15 is connected to one side of another side support frame 1. One end of the conveying shaft 51 is rotatably connected to one side of one of the side support frames 1.

[0106] One of the rotating gears 52 is connected to the output end of the power source 53, which is connected to the inner cavity of the protective frame 15.

[0107] In this technical solution, the conveying component 5 can be used to actively guide and convey the mulch film.

[0108] In use, the plastic film passes between the two conveying shafts 51 and is driven by the conveying power source 53 to rotate the corresponding rotating gear 52, which in turn drives the other rotating gear 52 to rotate. When the two rotating gears 52 rotate, they can drive the two conveying shafts 51 to rotate respectively, and the two conveying shafts 51 are used to actively convey and guide the plastic film.

[0109] The tops of both clamping components 3 are connected to the stabilizing component 7. The stabilizing component 7 includes multiple stabilizing shafts 71. The two ends of the multiple stabilizing shafts 71 are respectively connected to two side support frames 1. Two symmetrically distributed sliding plates 72 are slidably connected to the surface of the stabilizing shafts 71.

[0110] The two sliding plates 72 are located directly above the two mounting plates 31, and multiple connecting posts 73 connect the sliding plates 72 and the mounting plates 31, which are located on the same plane.

[0111] In this technical solution, the stabilizing component 7 can be used to limit the movement trajectory of the clamping component 3, making the stabilizing component 7 more stable when moving.

[0112] When the mounting plate 31 moves, it can drive the connecting column 73 to move in the same direction, which in turn drives the sliding plate 72 to move along the stabilizing axis 71. This allows the sliding plate 72 and the stabilizing axis 71 to support the mounting plate 31, increasing the stability of the mulch film roll during installation and limiting the movement trajectory of the mounting plate 31.

[0113] like Figure 10 , 11 As shown, the film pressing assembly 8 includes a mounting frame 81 and a film pressing wheel 82, with both ends of the film pressing wheel 82 rotatably connected to the inner walls of both sides of the mounting frame 81.

[0114] In this technical solution, the pressing assembly 8 is used to press and spread the mulch film to prevent the mulch film from being blown away by the wind and affecting the soil covering operation.

[0115] When in use, the film pressing roller 82 can roll along with the movement of the ridging and mulching machine to press and spread the mulch film.

[0116] The first control component 10 includes a bidirectional control screw 101. One end of the bidirectional control screw 101 is rotatably connected to one side of a side support frame 1, and the other end of the bidirectional control screw 101 is connected to a drive coupling component 12. The drive coupling component 12 is disposed in the inner cavity of the drive coupling protective frame 17, and the drive coupling protective frame 17 is connected to one side of another side support frame 1.

[0117] The surface of the regulating bidirectional screw 101 is threaded with two symmetrically distributed regulating plates 102. The bottom of each regulating plate 102 is connected to a lifting device 103, and the bottom of the lifting device 103 is connected to the top of the mounting frame 81.

[0118] In this technical solution, the height and lateral position of the pressure film assembly 8 can be adjusted using the first adjustment component 10.

[0119] In use, the drive assembly 12 drives the bidirectional control screw 101 to rotate, which in turn drives the control plates 102 on both sides to move in opposite directions along the fixed track 104. This causes the corresponding lifting device 103 and the mounting frame 81 to move in the same direction, adjusting the distance between the two mounting frames 81. Furthermore, depending on the ridging depth, the lifting device 103 can be used to move the mounting frame 81 and other structures up and down, thereby adjusting the height of the bottom of the pressing roller 82, thus adapting to various field conditions.

[0120] like Figure 12 , 13As shown, a scraping assembly 16 is provided on both sides of the pressing roller 82. The scraping assembly 16 includes an assembly plate 161. A plurality of inclined scrapers 162 are connected to the side of the assembly plate 161 near the pressing roller 82. The inclined scrapers 162 are inclined.

[0121] The other side of the assembly plate 161 is connected to a plurality of sliding shafts 163. The surface of the sliding shafts 163 is slidably connected to the side of the mounting frame 81. The ends of the plurality of sliding shafts 163 away from the assembly plate 161 are all connected to one side of the synchronization plate 164.

[0122] An elastic reset member 165 is connected between the assembly plate 161 and the inner side wall of the mounting frame 81.

[0123] During use, as the pressing roller 82 rotates, the inclined scraper 162 can scrape and clean the soil and other substances adhering to the surface of the pressing roller 82, so as to avoid the pressing roller 82 surface from having too many impurities adhering to it and affecting its use.

[0124] It is worth noting that multiple preset openings are provided on both sides of the mounting frame 81, through which soil and other impurities scraped by the inclined scraper 162 can be discharged.

[0125] The second control component 11 includes a control bidirectional screw 111, one end of which is rotatably connected to one side of a side support frame 1, and the other end of which is connected to the drive assembly 12.

[0126] The surface of the regulating bidirectional screw 111 is threaded with two symmetrically distributed regulating plates 112. The bottom of each regulating plate 112 is connected to a lifting device 113, and the bottom of the lifting device 113 is connected to the top of the soil covering component 9.

[0127] In this technical solution, such as Figure 14 As shown, the height and lateral position of the soil covering component 9 can be adjusted using the second control component 11.

[0128] In use, the drive assembly 12 can drive the regulating bidirectional screw 111 to rotate, thereby driving the regulating plates 112 on both sides to move in opposite directions along the fixed track 114, so that the corresponding lifting device 113 and the soil covering assembly 9 move in the same direction, and the distance between the two soil covering assemblies 9 can be adjusted; and according to the required ridging depth, the lifting device 113 can be used to drive the soil covering assembly 9 to move up and down, thereby adjusting the height of the soil covering assembly 9 to control the ridging depth, etc.

[0129] Multiple fixed rails 104 and fixed rails 114 are connected between the two side support frames 1. The surface of fixed rail 104 is slidably connected to the control plate 102, and the surface of fixed rail 114 is slidably connected to the control plate 112.

[0130] When in use, control plate 102 moves along fixed track 104, and control plate 212 moves along fixed track 214, so that fixed track 104 limits the movement trajectory of control plate 102, and fixed track 214 limits the movement trajectory of control plate 212.

[0131] Multiple linkage bars connect the control plate 102 and control plate 112 located on the same side.

[0132] The linkage bar allows control plate 102 and control plate 212 to move more synchronously.

[0133] The drive assembly 12 includes two drive sprockets 121, both of which are located inside the drive protection frame 17. The sides of the drive sprockets 121 are engaged with a drive chain 122, and the two drive sprockets 121 are connected by the drive chain 122. The two drive sprockets 121 are respectively connected to one end of a regulating bidirectional screw 101 and a regulating bidirectional screw 111. One end of the regulating bidirectional screw 101 and the regulating bidirectional screw 111 is rotatably connected through one of the side support frames 1. One of the drive sprockets 121 is connected to the output end of the drive power source 123, which is connected inside the drive protection frame 17.

[0134] In use, the drive power source 123 can drive the corresponding transmission sprocket 121 to rotate, which in turn drives the transmission chain 122 to rotate, and then drives another transmission sprocket 121 to rotate. When the two transmission sprockets 121 rotate, they can respectively drive the regulating bidirectional screw one 101 and the regulating bidirectional screw two 111 to rotate.

[0135] The elastic reset component 165 is a spring or other component with elastic reset function.

[0136] The power source 53, bidirectional drive source 61, and drive-coupled power source 123 are motors or other devices that can output rotational kinetic energy.

[0137] The lifting device 103 and lifting device 213 are electric push rods, lifting cylinders, hydraulic lifting cylinders, or devices with autonomous extension and retraction functions.

[0138] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples. Various changes or modifications can be made to these embodiments without departing from the principles and essence of this utility model, and all such changes and modifications fall within the protection scope of this utility model.
