Description

Technical Field

[0001] This invention relates to the field of laser leveling technology, specifically to a dual-control, multi-functional laser leveling machine. Background Technology

[0002] A laser grader is an intelligent device that uses laser technology to achieve high-precision land leveling. It is mainly used in two major fields: agricultural farmland leveling and building concrete floor construction. Its core principle is to control the raising and lowering of mechanical shovels through a laser reference plane to achieve automated leveling operations.

[0003] The dual-control agricultural laser leveler is an intelligent land leveling device that uses dual laser receivers or dual hydraulic systems for independent control. It solves the tilting problem of traditional single-control systems in sloping and corner areas by using left and right separation leveling technology, which significantly improves the leveling accuracy and operation efficiency of farmland.

[0004] When existing laser graders are in operation, if the soil is too hard, simply leveling the slope with the grader is often insufficient, resulting in soil remaining on the slope and the land still being uneven. Furthermore, leveling overly hard soil can damage the grader's blades, affecting its service life. This is a problem that needs to be solved. Moreover, laser grading addresses macroscopic elevation differences in the land, but it cannot affect the microscopic soil structure. Therefore, after grading, loose pores may still exist on the soil surface, leading to soil moisture evaporation and seepage. How to reduce the formation of these pores is also a problem that needs to be solved. Summary of the Invention

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0036] Please see Figure 1 - Figure 11 A dual-control multi-functional laser land leveler includes a body 1 and a bucket 102 fixedly connected to one side surface of the body 1. A plow frame 5 is fixedly connected to one side surface of the body 1. A soil loosening component is provided on the plow frame 5. A through hole 105 is provided on the bucket 102. A conversion component is provided in the through hole 105. A fixing plate 7 is fixedly connected to one side surface of the bucket 102. A soil pressing component is provided on the fixing plate 7.

[0037] As the machine moves forward, the soil loosening component first loosens the soil to reduce the resistance of the bucket 102. The soil loosening component will generate vibration when loosening the soil. The conversion component will transmit the force generated by the vibration to the soil compaction component so that the soil compaction component can flatten the soil after it has been shoveled.

[0038] This invention reduces the resistance of the bucket 102 and extends its service life by setting a soil loosening component to loosen the soil before leveling. The soil loosening component generates vibration during soil loosening, and the conversion component transmits the force generated by the vibration to the soil compaction component, so that the soil compaction component can flatten the leveled soil, improve the flatness of the land, and enhance the leveling effect.

[0039] In a further embodiment of the present invention, the soil loosening component includes a connecting groove 501 disposed on the plow frame 5, and one end of the connecting groove 501 is provided with a round hole, and a transmission rod 505 is slidably connected in the round hole. A connecting seat 502 is provided on the lower surface of the plow frame 5, and a soil loosening plow 503 is hinged in the connecting seat 502. One end of the transmission rod 505 is adapted to the upper end position of the soil loosening plow 503. A soil loosening spring 504 is connected between the connecting groove 501 and the soil loosening plow 503, and the soil loosening spring 504 is disposed on the surface of the transmission rod 505.

[0040] Furthermore, the loosening spring 504 is sleeved on the surface of the transmission rod 505, with one end connected to one end of the connecting groove 501 and the other end connected to the upper end of the loosening plow 503, and the transmission rod 505 and the connecting groove 501 are in sliding fit; there is a distance between one end of the transmission rod 505 and the upper end of the loosening plow 503, so that when one loosening plow 503 moves to plow the soil, the other loosening plows 503 will not affect each other's movement, but can all drive the subsequent transmission frame 506 to move; the loosening spring 504 is a high compression spring, so that the loosening plow 503 will not move arbitrarily and thus cannot till the soil.

[0041] Furthermore, the loosening plow 503 loosens the soil before leveling, reducing the resistance of the bucket 102 and extending its service life.

[0042] Specifically, if there are hard objects such as stones in the soil, the loosening plow 503 will rotate backward within the connecting seat 502 when it encounters them, in order to avoid the hard objects and thus protect the loosening plow 503 from being broken by the hard objects. The hardness of different parts of the soil is different. When plowing the hard soil, the loosening plow 503 rotates backward, while when plowing the soft soil, it will return to its original position and move forward under the action of the loosening spring 504, thereby driving the transmission rod 505 to slide back and forth. The setting of multiple loosening plows 503 ensures that there is always a transmission rod 505 sliding back and forth.

[0043] In a further embodiment of the present invention, the soil compaction assembly includes a mounting base 701 disposed on the lower surface of the fixing plate 7, and a fixing rod 702 is hinged inside the mounting base 701, and a connecting block 604 is fixedly connected to the lower end of the fixing rod 702.

[0044] In a further embodiment of the present invention, the soil pressing assembly further includes a second soil pressing seat 805 disposed on one side surface of the connecting block 604, and a second soil pressing rod 806 is hinged inside the second soil pressing seat 805. One end of the second soil pressing rod 806 is connected to a soil pressing spring 804, and one end of the soil pressing spring 804 is connected to a first soil pressing rod 803. One end of the first soil pressing rod 803 is hinged to a first soil pressing seat 802, and one end of the first soil pressing seat 802 is fixedly connected to a connecting strip 801. The lower end of the connecting strip 801 is fixedly connected to a soil pressing plate 8.

[0045] Furthermore, the soil pressing spring 804 is a high-compression spring, which prevents the soil pressing plate 8 from being moved arbitrarily by the movement of the machine body 1, and the soil pressing plate 8 is slidably connected to the machine body 1, with the sliding connection direction being up and down sliding.

[0046] Furthermore, the soil compression spring 804 increases the vibration frequency of the soil compression assembly by compressing and then resetting itself.

[0047] In a further embodiment of the present invention, the conversion assembly includes a mounting groove 101 disposed on one side surface of the body 1, and a transmission frame 506 is slidably connected in the mounting groove 101. One end of the transmission rod 505 is fixedly connected to one side surface of the transmission frame 506, and a transmission tube 6 is hinged to the other side surface of the transmission frame 506. A connecting block 604 is provided with a connecting hole, and a conversion tube 601 is rotatably connected in the connecting hole. One end of the transmission tube 6 away from the transmission frame 506 passes through the through hole 105 and is slidably sleeved inside the conversion tube 601. A conversion groove 602 is provided on the side wall of the conversion tube 601, and a conversion column 603 is slidably disposed in the conversion groove 602. The inner end of the conversion column 603 is fixedly connected to the surface of the transmission tube 6. One end of the conversion tube 601 passes through the connecting hole and is fixedly connected to an eccentric wheel 605. The conversion tube 601 is rotatably connected to the connecting hole.

[0048] Furthermore, the conversion groove 602 has a spiral groove structure, and the eccentric wheel 605 has a semi-circular structure.

[0049] Furthermore, when the transmission rod 505 slides back and forth, it drives the transmission tube 6 to slide back and forth within the conversion tube 601. Under the combined action of the conversion groove 602 and the conversion column 603, the sliding motion is converted into the rotational motion of the conversion tube 601, thereby driving the eccentric wheel 605 to rotate.

[0050] Specifically, when the eccentric wheel 605 rotates, it continuously changes the position of its center of gravity, thereby causing the soil pressing plate 8 below it to vibrate up and down to press the soil. At the same time, the change in the position of the center of gravity of the eccentric wheel 605 will also cause the connecting block 604 to move, causing it to swing around the mounting base 701 as the axis, thereby repeatedly compressing and stretching the soil pressing springs 804 on both sides, so that the soil pressing springs 804 can increase the vibration frequency and force of the soil pressing plate 8.

[0051] Furthermore, the hinge direction between the transmission frame 506 and the transmission tube 6 is horizontal, that is, when the connecting block 604 swings, the transmission tube 6 swings horizontally accordingly. The size of the through hole 105 is slightly larger than that of the transmission tube 6, so that when the connecting block 604 swings, the transmission tube 6 will move within the through hole 105, so that the transmission tube 6 will swing slightly with its hinge end as the axis.

[0052] Furthermore, during the rotation of the eccentric wheel 605, when it rotates to the horizontal direction, the change in center of gravity causes the connecting block 604 to shift in horizontal position, causing the connecting block 604 to swing, thereby increasing the vibration frequency of the soil pressing plate 8 by the soil pressing spring 804; when it rotates to the vertical direction, it directly causes the soil pressing plate 8 to vibrate.

[0053] In a further embodiment of the present invention, a frame 103 is fixedly connected to one side surface of the body 1, a traction seat 201 is provided on one side surface of the frame 103, a traction frame 2 is hinged in the traction seat 201, and a mounting hole is provided at one end of the traction frame 2, and a connector 202 is rotatably connected in the mounting hole.

[0054] Specifically, connector 202 is used to connect to the drive unit of the grader, which is generally connected to an agricultural vehicle so that the vehicle can drive the grader for mobile operations.

[0055] In a further embodiment of the present invention, a laser receiver 104 is provided on the upper surface of the frame 103.

[0056] Specifically, an external laser emitter, based on existing technology, is installed next to the land during operation. After scanning the land, the laser emitter generates a rotating laser plane as a reference, providing real-time feedback on height deviation. The laser receiver 104 receives the laser signal.

[0057] In a further embodiment of the present invention, a first hinge seat 401 is provided on the upper surface of the bucket 102, a second hinge seat 402 is provided on one side surface of the bucket 102, a wheel frame 405 is hinged inside the second hinge seat 402, an outer shaft 407 is fixedly connected to one end of the wheel frame 405, a wheel axle 403 is rotatably connected inside the outer shaft 407, a wheel 404 is provided at one end of the wheel axle 403, a third hinge seat 406 is fixedly provided on the surface of the outer shaft 407, and a hydraulic rod 4 is hinged between the first hinge seat 401 and the third hinge seat 406.

[0058] Furthermore, the wheel frame 405 and its components are in two sets, mirror-symmetrical about the vertical line of the bucket 102.

[0059] Specifically, the two sets of wheel frames 405 and hydraulic rods 4 enable the bucket 102 to tilt on slopes and corners while controlling its height. This allows for precise adjustment of the left and right sides of the bucket 102, thus solving the problem of tilting or unevenness that often occurs when the grader operates on slopes and corners.

[0060] Furthermore, when both sets of hydraulic rods 4 work simultaneously, they adjust the height of the wheels 404, thereby adjusting the height of the bucket 102; when the two sets of hydraulic rods 4 work individually, they adjust the angle of the bucket 102.

[0061] In a further embodiment of the present invention, an oil tank 3 is provided on the upper surface of the frame 103, and an oil filling valve 301 is connected to the upper surface of the oil tank 3. An electric oil pump 302 is also provided on the upper surface of the oil tank 3. An oil suction pipe 303 and an oil passage pipe 304 are connected to the electric oil pump 302. One end of the oil suction pipe 303 is connected to the inside of the oil tank 3, and the oil passage pipe 304 is connected to the hydraulic rod 4.

[0062] Specifically, the electronically controlled oil pump 302 is equipped with a controller of the prior art. After the laser receiver 104 receives the laser signal, the electronically controlled oil pump 302 controls the oil inlet and outlet of the oil pipe 304 to control the extension and retraction of the hydraulic rod 4, thereby controlling the raising and lowering of the two sets of wheel frames 405.

[0063] In this invention, a laser emitter is first placed next to the land. After scanning the land, the laser emitter generates a rotating laser plane as a reference, providing real-time feedback on height deviation. The laser receiver 104 receives the laser signal. Then, the grader is connected to a vehicle via a connector 202. The vehicle is started, driving the grader to move and level the soil on mounds above the reference surface using the bucket 102, accumulating the soil in the bucket 102. When the grader reaches a pit below the reference surface, the soil in the bucket 102 falls to fill the pit, thus ensuring that the overall height of the land is above the reference surface. During operation, the laser receiver 104 receives signals in real time to control the operation of the electronically controlled oil pump 302, thereby controlling the extension and retraction of the hydraulic rod 4, which in turn pulls or pushes the outer shaft 407, causing the wheel frame 405 to rotate on the second hinge seat 402, which in turn drives the wheel 404 to rise and fall to control the height of the wheel 404, thereby adjusting the height and angle of the bucket 102 in real time according to the land conditions; when performing leveling operations, the loosening plow 503 first loosens the soil and rotates back and forth during tilling, thereby driving the transmission rod 505 to slide back and forth under the action of the loosening spring 504, which in turn drives the transmission tube 6 to slide back and forth in the conversion tube 601, and in the conversion groove 6 Under the combined action of 02 and conversion column 603, the sliding motion is converted into the rotational motion of conversion tube 601, thereby driving the eccentric wheel 605 to rotate. When the eccentric wheel 605 rotates, it continuously changes the position of its center of gravity, thereby driving the soil pressing plate 8 below it to vibrate up and down to press the soil. At the same time, the change in the position of the center of gravity of the eccentric wheel 605 will also drive the connecting block 604 to move, causing it to swing around the mounting base 701 as the axis, thereby repeatedly compressing and stretching the soil pressing springs 804 on both sides. This makes the soil pressing springs 804 strengthen the vibration frequency and force of the soil pressing plate 8, thereby flattening the leveled soil, improving the flatness of the land, and enhancing the leveling effect.

[0064] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
