Description

Technical Field

[0001] The present application relates to the technical field of agricultural machinery, and in particular to a suppression structure of a self-powered rotary tiller. Background Art

[0002] When a rotary tiller is in operation, the engine's power, transmitted through the transmission system, causes the rotary blades to rotate at high speed, cutting into the soil. As the tiller advances, the blades continuously cut, crush, and turn the soil. During this rotation, the blades lift the soil from the bottom upwards, breaking larger clods into smaller particles. This loosens, finesses, and levels the soil, creating favorable conditions for subsequent agricultural operations such as sowing and fertilizing.

[0003] After conventional rotary tillers have been used, the soil surface often becomes uneven and undulating. This unevenness can hinder subsequent operations such as sowing and fertilizing. For example, when sowing with a seeder, uneven soil can lead to inconsistent sowing depths, affecting seed distribution and growth. Therefore, a pressure mechanism is typically incorporated into the machine body. This not only compacts the soil but also effectively smooths out small lumps and bumps on the surface, making the ground smoother and providing a good foundation for subsequent precision agriculture operations.

[0004] The above-mentioned existing technical solutions have the following drawbacks: the tillage depth of the rotary tiller can be adjusted according to crop planting requirements and soil conditions. When the tillage depth is shallow, the soil is less disturbed and the required compaction depth is also relatively shallow. If the compaction structure cannot be adjusted, the compaction effect will be poor. Utility Model Content

[0005] In order to achieve the purpose of improving the suppression effect on turned soil, the present application provides a suppression structure of a self-powered rotary tiller.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A suppression structure of a self-powered rotary tiller includes a connecting piece, which is connected to a frame, and the other end of the connecting piece is connected to a suppression wheel, which is rotatably connected to the connecting piece, and is used to suppress the land after rotary tillage; a lifting assembly is provided between the connecting piece and the suppression wheel, and there are at least two lifting assemblies, which are respectively provided on both sides of the suppression wheel, each lifting assembly includes a fixed plate and an opening and closing assembly, and a slide groove is provided in the vertical direction of the fixed plate, and the two sides of the suppression wheel are respectively inserted into the two slide grooves, and the opening and closing assembly is used to lock the relative position relationship between the suppression wheel and the slide groove; a driving assembly for controlling the lifting and lowering of the suppression wheel along the slide groove is provided on the frame.

[0008] By adopting the above scheme, the distance between the pressing wheel and the soil can be controlled by adjusting the relative position relationship between the two sides of the pressing wheel and the two chutes; and because an opening and closing component is provided, the opening and closing component can lock the relative position relationship between the pressing wheel and the chute; because the height of the pressing wheel can be adjusted, the tillage depth can be determined according to different soil characteristics, and then the distance between the pressing wheel and the soil can be determined according to the tillage depth; this setting can be adapted to local conditions and achieve the purpose of improving the suppression effect of the turned soil.

[0009] Furthermore, an elevation frame is provided on the upper surface of the connecting member, and the elevation frame is U-shaped, with both ends of the elevation frame fixedly connected to the connecting member and vertically corresponding to the two fixed plates respectively; two drive assemblies are provided, and each end of the pressing wheel corresponds to a drive assembly, and each drive assembly includes a pull rope, a positioning wheel and a winding wheel, the positioning wheel is connected to the inflection point of the elevation frame, the winding wheel is fixedly connected to the horizontal rod of the elevation frame, one end of the pull rope is connected to the pressing wheel, and the other end of the pull rope passes through the positioning wheel and is wound around the winding wheel (.

[0010] By adopting the above solution, the setting of the raising frame increases the stretching distance of the pull rope; by rotating the reel, the reel can reel in or unreel the pull rope, and when the reel reels in the pull rope, the pull rope drives the pressure wheel to move along the slide groove away from the ground; because a positioning wheel is provided, the setting of the positioning wheel achieves the effect of tensioning the pull rope, which can prevent the pull rope between the reel and the pressure wheel from loosening; and the setting of the positioning wheel makes the pull rope between the reel and the positioning wheel remain horizontal, and the pull rope between the positioning wheel and the pressure wheel remain vertical, which makes the process of rotating the reel to drive the pull rope to move more labor-saving.

[0011] Furthermore, a linkage assembly is provided between the two winding wheels, and the linkage assembly includes a first gear, a second gear and an electric drive component. The first gear and the second gear are both arranged on the side of the elevated frame away from the winding wheel. The first gear and the second gear are both rotatably connected to the elevated frame, and the two are meshed. The axles of the two winding wheels pass through the elevated frame and are fixedly connected to the first gear and the second gear respectively. The output end of the electric drive component is used to drive the first gear to rotate.

[0012] By adopting the above solution, the driving member drives the first gear to rotate. Since the first gear is meshed with the second gear, the second gear rotates synchronously. The rotation of the first gear and the second gear can drive the two winding wheels to rotate, thereby achieving the effect that one driving member can drive the two winding wheels to perform winding operations at the same time.

[0013] Furthermore, each of the opening and closing components includes a first limit plate and a second limit plate, the first limit plate and the second limit plate are both passed through the connecting shaft of the pressing wheel and are respectively located on both sides of the fixed plate; a locking assembly is provided in each first limit plate and the second limit plate, and each locking assembly includes a support rod, a first locking plate, a second locking plate and a telescopic rod, one end of the support rod is fixedly connected to the first limit plate, and the other end is fixedly connected to the first locking plate; the telescopic rod is arranged between the second locking plate and the second limit plate, and the two ends of the telescopic rod are respectively fixedly connected to the second limit plate and the second locking plate; through holes are provided on the first locking plate and the second locking plate, and corresponding through holes are provided with top screws and nuts, and the top screws pass through the through holes on the first locking plate and the second locking plate and are threadedly connected to the nut; when the second locking plate abuts against the first locking plate, the telescopic rod is in a maximum tension state.

[0014] By adopting the above solution, because a telescopic rod is provided, the second locking piece can be toggled in a direction close to the first locking piece until the first locking piece abuts against the second locking piece. At this time, the through holes on the first locking piece and the second locking piece correspond one to one, and then the first locking piece and the second locking piece are connected using a top screw and a nut to lock the relative position relationship of the first locking piece; when the first locking piece and the second locking piece are locked with each other, the first limit plate and the second limit plate lock the fixed plate, and the first limit plate and the second limit plate cannot move relative to the fixed plate, so the pressing wheel cannot slide up and down along the slide groove, thereby locking the relative position relationship between the pressing wheel and the fixed plate.

[0015] Furthermore, an elastic member is provided between the second limiting plate and the locking member, and two ends of the elastic member are fixedly connected to the second limiting plate and the second locking piece respectively.

[0016] By adopting the above solution, because an elastic part is provided, when the nut is rotated so that the nut is disengaged from the top screw, the elastic part can retract under its own elastic action, so that the second locking plate is separated from the first locking plate, thereby releasing the limitation of the first limiting plate and the second limiting plate on the fixed plate. At this time, the driving assembly can drive the pressing wheel to rise and fall along the slide groove.

[0017] Furthermore, the positioning wheel and the winding wheel are both connected with anti-slip parts, and the anti-slip parts are L-shaped.

[0018] By adopting the above solution, the provision of the anti-slip component can prevent the pull ropes on the positioning wheel and the winding wheel from falling off.

[0019] Furthermore, each of the pull ropes is correspondingly provided with a limiting ring, one end of the limiting ring is fixedly connected to the raising frame, and the pull rope is passed through the limiting ring.

[0020] By adopting the above solution, the setting of the limiting ring can limit the pull rope.

[0021] Furthermore, the rotating end of each of the jackscrews is fixedly connected to an enlarged plate, and the provision of the enlarged plate facilitates the rotation of the jackscrew.

[0022] By adopting the above solution, the arrangement of the enlarged plate facilitates the rotation of the top screw, making the rotation of the top screw more labor-saving.

[0023] In summary, this application has the following technical effects:

[0024] 1. With this structure, the distance between the pressing wheel and the soil can be controlled by adjusting the relative position of the two sides of the pressing wheel and the two chutes. In addition, an opening and closing assembly is provided to lock the relative position of the pressing wheel and the chutes. Since the height of the pressing wheel can be adjusted, the tillage depth can be determined according to different soil characteristics, and then the distance between the pressing wheel and the soil can be determined according to the tillage depth. This arrangement can be adapted to local conditions and achieves the purpose of improving the pressing effect on the turned soil.

[0025] 2. By setting up a linkage assembly, the rotation of the first gear and the second gear can drive the two winding wheels to rotate, achieving the effect that one driving member can drive the two winding wheels to perform winding operations simultaneously;

[0026] 3. By setting up the positioning wheel, the pull rope is tensioned, which can prevent the pull rope between the winding wheel and the pressing wheel from loosening; and the setting of the positioning wheel makes the pull rope between the winding wheel and the positioning wheel remain horizontal, and the pull rope between the positioning wheel and the pressing wheel remain vertical, making it more labor-saving to rotate the winding wheel to drive the pull rope to move.
