Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to the field of furrowing and ridging machinery and equipment, and specifically refers to a ridge wall beating device for a furrowing and ridging machine. Background Art

[0002] In modern agricultural production, furrowing and ridging machines, as important agricultural machinery and equipment, are widely used in the planting and field management of various crops. The main function of furrowing and ridging machines is to provide a good growth environment for crops and improve soil water retention capacity and fertilizer utilization rate through furrowing and ridging operations. However, in actual use, traditional furrowing and ridging machines often only focus on the basic functions of furrowing and ridging, while ignoring the compactness of the ridge wall soil.

[0003] The compactness of the ridge wall soil has an important impact on the growth of crops. If the ridge wall soil is too loose, it will not only easily lead to soil erosion, but also affect the root development and stability of crops. Therefore, after ridge formation, patting and compacting the ridge wall soil is an important step to ensure the normal growth of crops and increase yields.

[0004] At present, most of the furrowing and ridging machines on the market are not equipped with a special ridge wall beating device, or the beating effect is not ideal. The reason is that the ridge wall beating device equipped with the existing furrowing and ridging machines has problems such as the beating angle cannot be adjusted or the angle adjustment range is small, and the beating angles on both sides cannot be adjusted separately. Therefore, when the ridge wall angle exceeds the beating angle range of the ridge wall beating device or the ridge wall angles on both sides are inconsistent, the ridge wall cannot be fully beaten. In planting operations on slopes or mountains, this problem is particularly important due to the influence of terrain conditions.

[0005] At the same time, the ridge wall beating devices equipped on the existing furrowing and ridging machines mostly perform beating operations while the furrowing and ridging machines are moving forward. During the beating process, they are easily affected by soil and stones and become stuck, thereby causing damage to the beating devices and affecting the normal operation of the ridge wall beating devices.

[0006] In addition, existing furrowing and ridging machines usually use a gearbox to output power to the working devices including the furrowing device, the ridge wall beating device, etc. and the traveling device respectively. However, in actual use, due to the differences in the power requirements of the traveling device and the working device, for example, the traveling device requires a stable driving force to maintain the stability of speed and direction, while the working device requires a larger torque and different speeds to operate. Therefore, using one gearbox to meet these different requirements will lead to a lower operating efficiency and poorer operating effect of the ridge wall beating mechanism. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a ridge wall beating device for a furrowing and ridging machine, which has good operating effect, high efficiency and can reduce the labor intensity of farmers.

[0008] The utility model is realized through the following technical scheme, and provides a ridge wall beating device for a furrowing and ridging machine, comprising a power device, on which a first gear box is installed, and in addition, a transmission assembly is also included, wherein the transmission assembly is installed on the first gear box, a mounting frame is fixedly connected to the transmission assembly, and a beating transmission shaft and a swing plate are rotatably connected to the mounting frame respectively, one end of the beating transmission shaft is transmission-connected to the first gear box through the transmission assembly, and the other end is fixedly connected to an eccentric wheel, a pull rod assembly is eccentrically hinged on the eccentric wheel, and the The other end of the pull rod assembly is eccentrically hinged on the swing plate, and the eccentric wheel, pull rod assembly and swing plate form an eccentric connecting rod mechanism. Flapping plates are provided on the left and right sides of the swing plate, and the flapping plates are located on the rear side of the furrowing knife on the furrowing and ridging machine. Connecting rod assemblies are respectively provided on the flapping plates on the left and right sides, one end of the connecting rod assembly is hinged to the flapping plate and the other end is eccentrically hinged to the swing plate, and the bottoms of the flapping plates on the left and right sides are respectively hinged to the mounting frames, and a guide plate is provided on the side of the flapping plate located on the forward direction of the furrowing and ridging machine.

[0009] In this scheme, the power device drives the eccentric wheel to rotate through the first gear box, the transmission assembly, and the flap transmission shaft. Since the two ends of the pull rod assembly are eccentrically hinged on the eccentric wheel and the swing plate, and the eccentric wheel, the pull rod assembly, and the swing plate are eccentric connecting rod mechanisms, when the eccentric wheel rotates, the swing plate can be driven to perform reciprocating rotation through the pull rod assembly; when the swing plate rotates, since the bottoms of the flap plates on the left and right sides are respectively hinged to the bottom of the mounting frame, the swing plate is hinged on the swing plate and the flap plates through the two ends. The connecting rod assembly on the beating plate can simultaneously drive the beating plates on the left and right sides to perform beating actions; since the beating plate is located on the rear side of the furrowing knife on the furrowing and ridging machine, the beating plate can perform beating operations on the ridge wall in the furrow opened by the furrowing knife; by providing a guide plate on the side of the beating plate located in the forward direction of the furrowing and ridging machine, it can be prevented that the beating plate is stuck in the soil or stones when performing a beating operation during the forward process of the furrowing and ridging machine, thereby preventing the beating plate from being damaged and ensuring the normal progress of the beating operation.

[0010] Preferably, the transmission assembly includes a second gearbox, a first driving sprocket, and a driven sprocket, the second gearbox is installed on the first gearbox, and the second gearbox is provided with a first transmission shaft, a second transmission shaft, and a third transmission shaft in parallel, the first transmission shaft is transmission-connected to the first gearbox, a double gear is provided on the first transmission shaft, the first transmission gear and the second transmission gear are fixedly connected to the second transmission shaft, the third transmission shaft is fixedly connected to the third transmission gear, the double gear is meshed with the first transmission gear, the second transmission gear is meshed with the third transmission gear, one end of the third transmission shaft is located outside the box body of the second gearbox and is fixedly connected to the first driving sprocket, the driven sprocket is fixedly connected to the end of the beating transmission shaft away from the eccentric wheel, the first driving sprocket is transmission-connected to the driven sprocket through the first transmission chain, the second transmission shaft is also provided with a second driving sprocket, and the second driving sprocket is transmission-connected to the furrowing device of the furrowing and ridging machine through the second transmission chain.

[0011] In this optimization scheme, since the first transmission shaft is connected to the first gearbox, the double gear installed on the first transmission shaft meshes with the first transmission gear on the second transmission shaft, and the second transmission gear on the second transmission shaft meshes with the third transmission gear on the third transmission shaft, when the first gearbox inputs power to the first transmission shaft, it can drive the second transmission shaft and the third transmission shaft to rotate; at the same time, since one end of the third transmission shaft is located outside the housing of the second gearbox and is fixed with the first driving sprocket, the first driving sprocket is connected to the driven chain fixed to the beating transmission shaft through the first transmission chain, and the second transmission shaft is also provided with a second driving sprocket and the second driving sprocket is connected to the furrowing device of the furrowing ridging machine through the second transmission chain. Therefore, the power output by the first gearbox can be transmitted to the beating transmission shaft and the furrowing device through the first transmission shaft, thereby achieving the purpose of driving the eccentric connecting rod mechanism and the furrowing device to work.

[0012] Preferably, the double gear is slidingly and rotatably connected to the first transmission shaft, a shift fork is provided at the middle position of the double gear, and a fourth transmission gear is also provided on the third transmission shaft. The fourth transmission gear is adapted to the double gear, and the distance between the first transmission gear and the fourth transmission gear is greater than the thickness of the double gear. The first transmission gear and the fourth transmission gear are respectively located within the sliding range of the double gear, and there is a gap between the third transmission gear and the double gear for the sliding of the double gear.

[0013] In this optimization scheme, since the double gear is slidingly and rotatably connected with the first transmission shaft, and a shift fork is provided at the middle position of the double gear, the double gear can rotate with the first transmission shaft and can slide on the first transmission shaft along the axial direction of the first transmission shaft through the push of the shift fork; since the fourth transmission gear provided on the third transmission shaft is adapted to the double gear, the first transmission gear and the fourth transmission gear are respectively located within the sliding range of the double gear, and the distance between the first transmission gear and the fourth transmission gear is greater than the thickness of the double gear, so through the push of the shift fork, the double gear can be engaged with the first transmission gear or the fourth transmission gear separately to transmit power to the second transmission shaft or the third transmission shaft; since there is a gap between the third transmission gear and the double gear for the sliding of the double gear, the double gear can be avoided The wheel interferes with the third transmission gear during the sliding process; when the shift fork pushes the double gear to mesh with the first transmission gear, the first transmission shaft and the second transmission shaft rotate in opposite directions. Since the second transmission gear and the third transmission gear are meshed, the first transmission shaft and the third transmission shaft rotate in the same direction; when the shift fork pushes the double gear to mesh with the fourth transmission gear, the first transmission shaft and the third transmission shaft rotate in opposite directions. Since the third transmission gear drives the second transmission shaft to rotate through the second transmission gear, the first transmission shaft and the second transmission shaft rotate in the same direction at this time. Since the second transmission shaft is connected to the ditching device through the second active sprocket and the second transmission chain, the double gear can make the second transmission shaft rotate forward or reverse by meshing with the first transmission gear or the fourth transmission gear, thereby driving the ditching device to rotate forward or reverse. At the same time, since the third transmission shaft can drive the swing plate to perform reciprocating rotation through the eccentric connecting rod mechanism regardless of whether it rotates forward or reverse, the flapper can work normally regardless of whether the ditching device rotates forward or reverse.

[0014] Preferably, a tensioner wheel mounting bracket is fixedly connected to the position of the mounting frame corresponding to the first transmission chain, a tensioner wheel mounting bracket is rotatably connected to a tensioner wheel shaft, a tensioner wheel is rotatably connected to the tensioner wheel shaft, the tensioner wheel is located between the first driving sprocket and the driven sprocket, the tensioner wheel fits the working surface of the first transmission chain and the tensioner wheel applies pressure to the first transmission chain.

[0015] In this optimization scheme, since the tensioner is in contact with the working surface of the first transmission chain and applies pressure to the first transmission chain, the tensioner tightens the first transmission chain, thereby ensuring the working state and transmission efficiency of the first transmission chain and avoiding equipment failure caused by loosening of the first transmission chain.

[0016] Preferably, the pull rod assembly includes a first connecting block and a first screw rod, the first connecting blocks are respectively located at the front and rear ends of the pull rod assembly, the first connecting block is provided with a hinge hole for hinged connection, the first connecting block is provided with a threaded hole and the threaded hole is adapted to the first screw rod, one end of the first screw rod is threadedly connected to the first connecting block at one end of the pull rod assembly, and the other end of the first screw rod is threadedly connected to the first connecting block at the other end of the pull rod assembly through a universal joint.

[0017] In this optimization scheme, by adjusting the screwing depth of the first screw in the threaded hole of the first connecting block, the overall length of the tie rod assembly can be adjusted quickly and conveniently. When the eccentric wheel is in the same position, adjusting the overall length of the tie rod assembly can change the position of the hinge point between the tie rod assembly and the swing plate, so that the angles of the flapping plates on the left and right sides change synchronously during the flapping process. Therefore, in actual use, the flapping angle of the flapping plate can be made to fit the actual angle of the ridge wall more closely by adjusting the overall length of the tie rod assembly, thereby improving the flapping effect of the flapping plate. In addition, since the other end of the first screw is threadedly connected to the first connecting block at the other end of the tie rod assembly through a universal joint, in the process of the eccentric wheel driving the tie rod assembly to move, it can prevent the threaded holes of the first connecting blocks at both ends of the tie rod assembly from deforming and bending due to different axes or the eccentric connecting rod mechanism from getting stuck.

[0018] Preferably, the connecting rod assembly includes a second connecting block and a second screw rod. The second connecting blocks are respectively located at the front and rear ends of the connecting rod assembly. The second connecting block is provided with a hinge hole for hinged connection. The second connecting block is provided with a threaded hole and the threaded hole is adapted to the second screw rod. The two ends of the second screw rod are respectively threadedly connected to the second connecting blocks at both ends of the connecting rod assembly. The swing plate is provided with a plurality of hinge holes for hinged connection with the connecting rod assembly.

[0019] In this optimization scheme, by adjusting the screw-in depth of the second screw in the threaded hole of the second connecting block, the overall length of the connecting rod assembly can be conveniently adjusted. When the overall length of the connecting rod assembly corresponding to the left and right flapping plates is adjusted synchronously, the angles of the left and right flapping plates during the flapping process can be changed synchronously. When the overall length of the connecting rod assembly corresponding to the left and right flapping plates is adjusted separately, the angles of the left and right flapping plates during the flapping process can be adjusted separately. In addition, by adjusting the hinge position of the left and right connecting rod assembly on the swing disk, the opening and closing angles of the left and right flapping plates can also be adjusted. Therefore, farmers can adjust the overall length of the connecting rod assembly corresponding to the left and right flapping plates according to the actual terrain such as slopes and mountains, or adjust the hinge position of the connecting rod assembly on the swing disk, so that the flapping angle of the flapping plate is more in line with the actual angle of the ridge wall, thereby further improving the flapping effect of the flapping plate.

[0020] Preferably, the guide plate is vertically arranged on the beating plate, the width of the guide plate is greater than the depth of the beating plate immersed in the soil during the beating process, and the connection between the guide plate and the beating plate adopts an arc transition.

[0021] In this optimization scheme, since the guide plate is vertically arranged on the flapping plate, and the width of the guide plate is greater than the depth of the flapping plate immersed in the soil during the flapping process, it can prevent the flapping plate from getting stuck or damaged due to the flapping plate being immersed in the soil or hitting stones when the flapping plate moves forward with the furrowing and ridging machine and performs flapping operations. In addition, by setting an arc transition at the connection between the guide plate and the flapping plate, the guiding effect of the guide plate can be further improved, the flapping plate can be prevented from getting stuck, and the life of the flapping plate can be extended to ensure the smooth progress of the flapping operation.

[0022] Preferably, there is a gap between the bottom of the flapping board and the bottom of the ditch to prevent the flapping board from getting stuck, the spacing between the bottoms of the flapping boards on the left and right sides is adapted to the width between the ridge walls on both sides at the corresponding height of the ditch, the maximum angle of the vertical surfaces of the flapping boards on the left and right sides during the flapping process is not less than the angle of the ridge walls on both sides, and the minimum angle of the vertical surfaces of the flapping boards during the flapping process is less than the angle of the ridge walls on both sides.

[0023] In this optimization scheme, by setting a gap between the bottom of the flapping board and the bottom of the ditch, it is possible to prevent the bottom of the flapping board from rubbing against the bottom of the ditch when the flapping board moves with the furrowing and ridging machine. Since the spacing between the bottom surfaces of the left and right flapping boards is adapted to the width between the ridge walls on both sides at the corresponding height of the ditch, the maximum angle of the vertical surfaces of the left and right flapping boards during the flapping process is not less than the angle of the ridge walls on both sides, and the minimum angle of the vertical surfaces of the flapping boards during the flapping process is less than the angle of the ridge walls on both sides. Therefore, it can be ensured that the flapping boards can exert pressure on the surface of the ridge walls and sink into the soil during the flapping process, thereby improving the flapping effect. At the same time, when the flapping boards complete flapping, they can leave the ridge wall surface and will not scrape the soil on the ridge wall surface as the furrowing and ridging machine moves forward.

[0024] Preferably, the distance between the hinge point of the pull rod assembly on the eccentric wheel and the rotation axis of the eccentric wheel is smaller than the distance between the hinge point of the pull rod assembly on the swing plate and the rotation axis of the swing plate.

[0025] In this optimization scheme, since the distance between the hinge point of the pull rod assembly on the eccentric wheel and the rotation axis of the eccentric wheel is smaller than the distance between the hinge point of the pull rod assembly on the swing plate and the rotation axis of the swing plate, and the eccentric wheel, the pull rod assembly, and the swing plate are a new connecting rod mechanism, when the eccentric wheel drives the swing plate to rotate through the pull rod assembly, the movement mode of the eccentric wheel is continuous rotation, while the movement mode of the swing plate is reciprocating rotation, that is, the eccentric wheel rotates one circle, the swing plate rotates forward from the starting position to the end position, and then rotates back to the starting position, and the rotation angle of the swing plate is less than 360°. Since the movement mode of the swing plate is reciprocating rotation, the swing plate can drive the flapping plate through the connecting rod assembly to realize reciprocating flapping action, while avoiding interference between the connecting rod assemblies of the flapping plates on the left and right sides on the swing plate.

[0026] The utility model also discloses a furrowing and ridging machine, comprising any one of the above-mentioned ridge wall beating devices.

[0027] The beneficial effects of the utility model are as follows: through the utility model, the ridge walls on both sides of the ditch can be beaten during the operation of the ditching and ridging machine, and the angle of the beating plate can be adjusted according to the actual angle of the ridge walls on both sides according to the actual terrain conditions such as slopes and mountains, ensuring that the beating plate is in full contact with the ridge wall, greatly improving the ridge wall beating effect and applicability, avoiding manual secondary operations due to poor beating effects, reducing farmers' labor intensity, and improving farmers' labor efficiency.

[0028] At the same time, when the furrowing and ridging machine moves forward, it can prevent the flapping board from being stuck in the soil and stones during the beating process, causing damage to the flapping board, thereby extending the life of the flapping board and ensuring the work efficiency of the beating operation.

[0029] In addition, since a transmission assembly is used to output power to the furrowing mechanism and the ridge wall beating device in the utility model, the power requirements of the furrowing mechanism and the ridge wall beating device can be better met, the operating efficiency of the ridge wall beating is improved, and the reduction in operating efficiency caused by the traveling mechanism of the furrowing and ridging machine sharing a gear box with the furrowing mechanism and the ridge wall beating device is avoided.
