Technical Field

The present application belongs to the technical field of soil leveling devices, and specifically relates to a rice field adaptive leveling machine based on multi-dimensional adjustment.

Background Art

In rice planting and production, whether the rice field is flat is related to the quality of rice planting. The surface of the solid soil in the rice field will have different degrees of loose soil, which will lead to deviations in the depth of rice transplanting, and it is easy to cause the seedlings to fall or bury, causing rework and increasing workload; there are also uneven humps or pits on the soil surface, and the water depth around the humps and pits is different, which can easily lead to uneven water intake for the rice planted in the humps or pits, affecting the greening of the rice. The method of artificially leveling the field is not only too inefficient, but also affected by operating technology and labor allocation, and the effect is difficult to meet the planting needs.

In the prior art, a Chinese utility model with publication number CN213306127U discloses an agricultural soil leveling device, which includes a crossbeam frame, a suspension assembly is arranged at the upper end of the crossbeam frame, support columns are arranged at both ends of the crossbeam frame, the lower ends of the two support columns are hingedly provided with a fixed seat that can rotate in a vertical direction, a main scraper is arranged between the two fixed seats, and an auxiliary scraper that can rotate laterally is hingedly provided on the outer sides of the two fixed seats, a first hydraulic cylinder is installed at the lower end of the crossbeam frame, and a first telescopic shaft of the first hydraulic cylinder is hinged to one side of the upper end of the main scraper. Although the above-mentioned device can adjust the angle between the main scraper and the paddy field through the first hydraulic cylinder, so that the main scraper can scrape the paddy field flat while advancing along the horizontal plane, and the scraping width of the main scraper can be extended by the two unfolded auxiliary scrapers, the main scraper cannot actively make immediate adjustments according to the changes in the paddy field terrain during the operation, and it is easy to miss the leveling treatment of lower convexities and deeper pits; and the device only performs a single leveling treatment on the paddy field during the parallel advancement process. If the leveling effect is to be improved, multiple round trips are required, resulting in low leveling efficiency and long operation time.

The present application is further described in detail below in conjunction with Figures 1 to 3 and specific embodiments.

In the present application, a rice field adaptive leveling machine based on multi-dimensional adjustment is disclosed, including a tractor (not shown in the drawings) and a soil leveling device, wherein the tractor includes agricultural machinery equipment such as a tractor and a tillage tractor, and the soil leveling device includes a soil leveling component 10, a longitudinal swing component 20 and a lateral swing component 30, wherein the soil leveling component 10 includes a pair of longitudinal beams 11 and a plurality of soil pressing plates 12, and the plurality of soil pressing plates 12 are arranged between the pair of longitudinal beams 11 at intervals in front and back; the longitudinal swing component 20 includes a cross beam 21 and at least one first telescopic cylinder 22, the cross beam 21 is specifically composed of two long beams arranged in parallel in the transverse direction, and the long beams are connected by longitudinal connecting columns, and first arms 211 are symmetrically arranged at both ends of the cross beam 21, and the longitudinal beam 11 and the corresponding first arm 211 are rotatably connected by a rotating shaft arranged in the transverse direction, so that the cross beam 21 can bear the weight of the soil leveling component 10; in this embodiment, a first telescopic cylinder 22 is preferably 2, the two ends of the first telescopic cylinder 22 are respectively hinged to the midpoint of the front end or rear end of the crossbeam 21 and the midpoint of the soil pressing plate 12 at the front end or the rear end, so as to avoid uneven force on the first telescopic cylinder 22; when the device is in working state, the first telescopic cylinder 22 continuously performs reciprocating telescopic motion, so that the longitudinal beam 11 drives the soil pressing plate 12 to swing back and forth; the above-mentioned lateral swing assembly 30 includes a horizontal bracket 31 and at least two second telescopic cylinders 32, the horizontal bracket 31 is composed of two short beams arranged in parallel laterally, and the short beams are connected by connecting columns, the midpoint of the horizontal bracket 31 (i.e. the midpoint of the front end of the short beam) and the midpoint of the crossbeam 21 are rotatably connected by a rotating shaft arranged along the longitudinal direction, the two second telescopic cylinders 32 are symmetrically distributed on both sides of the horizontal bracket 31 in the transverse direction and the two ends are respectively hinged to the horizontal bracket 31 and the crossbeam 21, when the device is in working state, the two second telescopic cylinders 32 continuously perform reciprocating telescopic motion in opposite directions.

In order to keep the horizontal support 31 in a horizontal state at all times, the pair of second telescopic cylinders 32 can drive the cross beam 21 to swing with a set telescopic length, so as to ensure that the soil pressing plate always vibrates and presses the loose soil in the paddy field with the horizontal plane as the reference. A horizontal suspension assembly is also provided on one side of the horizontal support 31, and the horizontal suspension assembly is used to keep the horizontal support and the tractor horizontally connected, so that the horizontal support only retains the function of horizontal rotation relative to the tractor, and does not twist around the longitudinal axis.

Specifically, the first telescopic cylinder 22 and the second telescopic cylinder 32 include devices that may be used, such as hydraulic telescopic cylinders, pneumatic telescopic cylinders or electric telescopic cylinders, which transmit kinetic energy through reciprocating telescopic motion. In this embodiment, a telescopic cylinder that can reciprocate quickly is preferred. The fast telescopic cylinder can achieve fixed-frequency telescopic motion through debugging and a matching control mechanism, so that when the above-mentioned device is in a working state, the soil leveling component 10 can actively reciprocate within a certain spatial range in the horizontal and vertical directions, thereby achieving a vibration effect (the use of a "fast" telescopic cylinder is one of the conventional technical means to implement the present application, and its specific structure and working principle are not technical features necessary for solving the technical problem of the present application, so it is not described in detail herein, and will not be repeated hereafter); at least one pair of hinged ears for hingedly connecting the first telescopic cylinder 22 are respectively provided at the front end or rear end of the crossbeam 21 and the corresponding positions of the soil pressing plate 12, and a hinge shaft is rotatably provided between the ears, and the two ends of the first telescopic cylinder 22 are rotatably connected with the hinge shaft (the hinge structure of the second telescopic cylinder 32 is the same as the above-mentioned hinge structure); the paddy field adaptive leveling machine can be connected to a power traction equipment such as a tractor to perform paddy field leveling operations.

The use of the above-mentioned paddy field adaptive leveling machine can achieve at least the following technical effects:

The soil-leveling equipment is towed forward horizontally by a tractor, and the first telescopic cylinder 22 drives the soil pressing plate 12 to swing quickly and slightly in the front-rear direction, and the second telescopic cylinder 32 drives the soil pressing plate 12 to swing quickly and slightly in the left-right direction, so that the lower surface of the soil pressing plate 12 can be unaffected by the changes in the terrain height of the paddy field in a small range in the process of swinging, and the potholes within the range where the soil pressing plate 12 passes can be smoothed, thereby avoiding the situation in the prior art that some potholes are missed because the scraper cannot adjust the angle according to the change in terrain height; and several groups of soil pressing plates 12 arranged front and back can perform multiple smoothing and vibration compaction treatments on the paddy field soil within the operating range during one soil-leveling operation, thereby improving the flatness of the paddy field soil and the soil-leveling efficiency, and saving the soil-leveling operation time.

In addition, the present application also provides some more specific implementation methods to improve the above-mentioned rice field adaptive leveling machine.

Furthermore, the above-mentioned horizontal suspension assembly includes an equipment traction shaft 312, and a connecting plate 311 is fixed to the front end of the above-mentioned horizontal bracket 31. A rotating pin 3111 is rotatably provided on the connecting plate 311, and the rotating pin 3111 can rotate in a horizontal plane. The rotating pin 3111 is perpendicular to the axial sleeve and the equipment traction shaft 312 is provided. The end of the equipment traction shaft 312 away from the rotating pin 3111 is used to connect to agricultural machinery traction equipment such as a tractor.

Specifically, the traction equipment tows the above-mentioned rice field adaptive leveling machine in the water, and the water-up rotating pin 3111 can limit the equipment traction shaft 312 and the horizontal bracket 31 to deflect only on the horizontal plane, so that the device can turn with the traction equipment. During the leveling process, since the traction equipment usually has a suspension mechanism (such as a shock-absorbing spring used by the tractor to keep the body horizontal, etc.), the traction equipment can maintain horizontal advancement in the paddy field, so that the horizontal bracket 31 can remain relatively horizontal during the movement. After the horizontal bracket 31 is horizontal, the first telescopic cylinder 22 and the second telescopic cylinder 32 move with a fixed telescopic amount, which can make the soil pressing plate 12 vibrate and press the rice field with the horizontal plane as the reference surface, thereby improving the stability of the equipment.

Furthermore, the number of the above-mentioned soil pressing plates 12 is 2 to 4. Specifically, the number of soil pressing plates 12 is not the more the better, and the sum of the width of each soil pressing plate 12 and the width of the interval between the soil pressing plates 12 is not less than the longitudinal length range of the longitudinal beam 11. 2 to 4 soil pressing plates 12 can improve the soil pressing efficiency while reducing the weight of the entire device, and can reduce the working pressure of the first telescopic cylinder 22 and the second telescopic cylinder 32, ensuring that the swinging process is smooth and continuous.

Furthermore, since the length of the earth pressing plate 12 is much greater than its width, it may be deformed and bent due to local uneven force during the soil leveling process. In order to increase the strength of the earth pressing plate 12 and prevent the earth pressing plate 12 from deforming, the above-mentioned soil leveling component 10 also includes a plurality of reinforcing ribs 13. The reinforcing ribs 13 are spaced apart between the longitudinal beams 11 and are fixedly connected to each earth pressing plate 12 along the longitudinal direction to increase the strength of the earth pressing plate 12 and maintain the bending resistance of the earth pressing plate 12.

Furthermore, during the soil compacting process of the soil compacting plate 12, in order to prevent the stones, rice straw or stubble in front of the soil compacting plate 12 from turning over the soil compacting plate 12 and affecting the flat ground behind the soil compacting plate 12, an interception plate 121 is provided on the surface of the side of the soil compacting plate 12 facing away from the ground. The interception plate 121 forms an interception angle with the upper rear of the soil compacting plate 12. During the movement of the soil compacting plate 12, stones, straw and other debris on the bottom of the water are intercepted by the interception plate 121 and pushed forward, thereby further improving the flatness of the soil after being vibrated by the soil compacting plate 12.

Furthermore, in order to reduce the resistance of the above device traveling in water, the interception plate 121 is provided with a plurality of overflow holes 1211 in an array along the length extension direction of the interception plate 121. The overflow holes 1211 can allow muddy water to flow backward through the interception plate 121, thereby reducing the travel resistance and further reducing the weight of the soil leveling assembly 10, so that the soil leveling assembly 10 can be easily driven by the first telescopic cylinder 22 and the second telescopic cylinder 32.

Furthermore, in order to reduce the shear force on the first arm 211 when the leveling assembly 10 swings back and forth and increase the stability of the leveling assembly 10, the two first arms 211 are symmetrically provided with limit grooves 2111 along the rotation trajectory of the longitudinal beam 11, and a rolling pin 2112 is movably provided in the limit groove 2111, and the rolling pin 2112 can roll along the limit groove 2111; the second arm 111 is extended upward from the upper end of the longitudinal beam 11, and one end of the second arm 111 is rotatably connected to the rolling pin 2112 through a bearing.

During use of the above-mentioned device, the second arm 111 swings along the trajectory of the limiting groove 2111, which can reduce the shear force on the first arm 211 caused by the gravity and centrifugal force of the leveling component 10, reduce the influence of the shear force on the stability of the leveling component 10 during the swinging process, and extend the service life of the device; at the same time, the limiting groove 2111 can limit the front and rear swing amplitude of the leveling component 10, so that the leveling component 10 swings strictly according to the set trajectory and swing amplitude, further improving the swing stability.

In another embodiment, the above embodiment has the following differences:

The number of the above-mentioned first telescopic cylinders 22 is set to a pair, and the pair of first telescopic cylinders 22 are symmetrically distributed at the front end of the beam 21 with an axis perpendicular to the midpoint of the above-mentioned beam 21 as the symmetry axis, and the two ends of the two first telescopic cylinders 22 are respectively hinged to the beam 21 and the soil pressing plate 12.

The pair of first telescopic cylinders 22 can share the weight of the soil-leveling assembly 10 . Compared with the first embodiment, the pair of first telescopic cylinders 22 can perform telescopic motion synchronously, which can further improve the stability of the soil-leveling assembly 10 during the swinging process.

In another embodiment, the above embodiment has the following differences:

The number of the above-mentioned first telescopic cylinders 22 is set to two pairs, and any pair of the first telescopic cylinders 22 is symmetrically distributed at the front end of the beam 21 with an axis perpendicular to the midpoint of the beam 21 as the symmetry axis, and the other pair of the first telescopic cylinders 22 is symmetrically distributed at the rear end of the beam 21 with an axis perpendicular to the midpoint of the beam 21 as the symmetry axis.

Specifically, a pair of first telescopic cylinders 22 located at the front end of the beam 21 and a pair of first telescopic cylinders 22 located at the rear end of the beam 21 move in opposite directions. When one pair of first telescopic cylinders 22 is shortened, the other pair of first telescopic cylinders 22 is extended by a corresponding distance, which not only further reduces the force exerted on a single first telescopic cylinder 22, but also improves the driving efficiency and the swing stability of the leveling assembly, thereby helping to extend the service life of the rice field adaptive leveling machine.

Combined with the above structures, the above-mentioned rice field adaptive leveling machine can achieve dead-angle leveling operations through stable swinging, and can avoid the influence of debris in the water on the flatness of the land during the leveling process. The overall structure of the device is simple and practical, and can achieve good leveling efficiency and leveling effect with low maintenance cost and manufacturing cost.

Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
