Description

Technical Field

[0001] The invention relates to the technical field of agricultural implements, and in particular to an agricultural micro-slope leveling device and method. Background Art

[0002] Agricultural micro-slope leveling devices are mainly used in the agricultural field, especially in precision agriculture, for land leveling, irrigation water flow control, and improving land use efficiency. Traditional farmland leveling operations are mostly carried out manually or with simple mechanical equipment, usually relying on experienced farmers. These methods are inefficient when dealing with large areas of farmland, and the leveling accuracy is limited, which can easily lead to uneven land, water accumulation or poor water flow, affecting crop growth.

[0003] Although agricultural micro-slope leveling devices play an important role in agricultural production, there are still some problems in practical applications. Agricultural micro-slope leveling devices have poor adaptability when facing different terrains and soil conditions. For example, the equipment may not be able to operate stably in soft or muddy soils, resulting in reduced operating efficiency. For areas with large slope changes, the adjustment capacity of the device is also limited, and it cannot flexibly respond to terrain undulations. In addition, the current machine operation is complex and the degree of automation is not high. Although some equipment uses intelligent control systems, the overall operation is still relatively complex, and farmers need to undergo certain training to master it proficiently. For small farmers, the operating threshold of highly automated devices is high, and it is difficult to popularize them. In addition, some automated equipment is highly dependent on components such as sensors and controllers. Once a component fails, the entire system may be seriously affected. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an agricultural micro-slope leveling device and method, which can complete slope scanning and precise leveling in one operation, is suitable for a variety of complex environments, and improves overall work efficiency.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In a first aspect, an embodiment of the present invention provides an agricultural micro-slope leveling device, comprising a frame and a scraper plate, a soil cutting knife group and a leveling roller group sequentially arranged on the frame, wherein the frame is equipped with a slope scanner;

[0007] The scraper board has an angle adjuster, which is used to adjust the angle of the scraper board entering the soil according to the slope information collected by the laser scanner; the soil cutting knife group includes a plurality of disc blades arranged side by side, and the leveling roller group includes a plurality of leveling rollers arranged side by side, and the leveling rollers have embossed ridges evenly distributed along their circumference.

[0008] As a further implementation, the scraper plate includes a scraper body, an angle adjuster and a blade. The scraper body is fixedly connected to the frame, and the angle adjuster is connected between the scraper body and the blade.

[0009] As a further implementation, when the scraper bar cuts the soil, the blade forms linear contact with the soil.

[0010] As a further implementation, each disc blade is mounted on the same main shaft, and the main shaft is rotatably connected to the frame.

[0011] As a further implementation, the disc blade has a crushing edge inside, and a cutting portion is formed on the outer periphery of the disc blade.

[0012] As a further implementation, each leveling roller is mounted on the same mounting shaft, and the mounting shaft is rotatably connected to the frame.

[0013] As a further implementation, the embossed ridges are cylindrical protrusions.

[0014] As a further implementation, the slope scanner includes a laser transmitter, a receiver and a controller, the laser transmitter is used to transmit a laser beam to obtain slope information, and the receiver is used to receive the information collected by the laser transmitter and send it to the controller.

[0015] In a second aspect, an embodiment of the present invention further provides a method for leveling an agricultural micro-slope, using the leveling device, comprising:

[0016] The slope scanner collects slope data and transmits it to the controller to dynamically adjust the moldboard angle;

[0017] The scraper board performs preliminary tillage and loosening on the soil surface to break up large soil clods; the soil cutter group further crushes the soil processed by the scraper board; the embossed ridges of the leveling roller group roll on the soil surface to eliminate tiny surface unevenness by applying local pressure.

[0018] As a further implementation, the leveling roller can adjust its working depth and compaction strength according to the data transmitted in real time by the slope scanner.

[0019] The beneficial effects of the present invention are as follows:

[0020] The operation process of the present invention is progressive, ensuring the leveling effect. The design of the leveling device follows the logical order from coarse to fine, from preliminary processing to fine shaping: the scraper first scrapes the soil over a large area to create conditions for subsequent precise crushing and leveling; the soil cutter group further refines the soil particles and evenly distributes the soil; finally, the leveling roller group realizes the overall leveling and compaction of the slope through compaction and fine-tuning; thus, the slope scanner, scraper, soil cutter group and leveling roller group form a precise match to jointly complete the soil processing and slope adjustment. Among them, the slope scanner can capture the ground slope data in real time and immediately feed it back to the scraper, and can automatically adjust the entry angle of the scraper blade, so that the leveling effect is more obvious; the slope scanner can quickly respond to the complex changes in the terrain. In the farmland with constantly changing slopes, real-time measurement and adjustment ensure that the soil cutter group and the leveling roller group are adjusted in time to adapt to the changing working environment. There is a crushing blade inside the disc blade, which can crush the soil for the second time while it is being cut, making the soil particles smaller; the crushing blade crushes the soil particles to prevent large pieces of soil from gathering inside the soil cutting device, reduce blockage, and ensure the continuity of the leveling operation.

[0021] The present invention can efficiently handle a variety of terrains and soil conditions. The three-part structure can adapt to different soil conditions and terrain conditions. The scraper board is responsible for basic tillage and is suitable for various soil types; the soil cutting knife group flexibly copes with the cutting and processing of harder objects such as soil blocks and root stubble; and the leveling roller group fine-tunes and compacts the final slope surface, making the device suitable for a variety of operating scenarios from more complex terrains to conventional farmland.

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] Embodiment 1:

[0031] The current agricultural micro-slope leveling device has low leveling accuracy and cannot meet the strict requirements of precision agriculture for micro-slopes. The existing devices are not adaptable enough to deal with complex terrain or different soil conditions, and are prone to blockage or unstable operation. Based on this, this embodiment provides an agricultural micro-slope leveling device, such as Figure 1-Figure 4 As shown, it includes a frame and a scraper plate 2, a soil cutting knife group 3 and a leveling roller group 4 which are sequentially arranged on the frame, and a slope scanner 1 is installed on the frame, which can complete slope scanning and precise leveling in one-time operation.

[0032] With reference to the actual moving direction of the device, the scraper blade 2 is located in front of the soil cutting knife group 3. As the initial operation part of the leveling device, its main function is to perform preliminary leveling and shaping of the soil. Figure 3 and Figure 4 As shown, the scraper plate 2 includes a scraper body 23, an angle adjuster 22 and a blade 21. The top of the scraper body 23 is fixedly connected to the frame, mainly providing overall support and stability; the blade 21 is installed at the bottom of the scraper body 23 through the angle adjuster 22, and the blade 21 is located on the front side of the scraper body 23 and is made of high-strength wear-resistant material; the angle of the blade 21 relative to the scraper body 23 is changed by the angle adjuster 22 to form different soil entry angles.

[0033] The blade 21 of the scraper plate 2 has a sharp edge, which can accurately flatten and correct the slope surface to make the leveled surface smoother and more uniform; when the scraper plate 2 cuts the soil, it mainly uses line contact to reduce the disturbance and turning of the soil, so as to better maintain the structure and moisture of the soil and avoid large-scale soil loosening. The angle adjustment of the blade 21 is based on the slope information collected in real time by the slope scanner 1. When the slope scanner 1 detects that the slope of the slope surface is high, the controller 13 can automatically adjust the angle of entry of the scraper plate 2 to increase the entry depth to achieve a more accurate leveling effect. The angle adjustment of the scraper plate 2 can cope with changes in different slopes, so that the leveling device can flexibly cope with different terrain conditions and is suitable for a variety of complex environments, especially complex terrain and irregular slopes, reducing repetitive work and improving overall work efficiency.

[0034] It should be noted that the angle adjuster 22 is a device that can achieve angle adjustment. For example, the angle adjuster 22 includes a motor and a rotating shaft. The blade 21 and the scraper body 23 are rotatably connected via the rotating shaft, and one end of the rotating shaft is connected to the motor.

[0035] The scraper blade 2 of this embodiment slides along the ground surface with its smooth blade 21, scrapes and leveled the high parts of the ground, and fills the low-lying areas to make the ground surface flat; it can effectively reduce the bumps and bumps in the soil, trim a more uniform thickness of the farmland, and provide a relatively flat foundation surface for subsequent operations. In addition, it can also push the debris and stones in the soil to the edge. This process provides a more uniform and soft working environment for the subsequent soil cutting knife group 3, making it more efficient in cutting and further refining the soil blocks.

[0036] The slope scanner 1 includes a laser transmitter 11, a receiver 12 and a controller 13. The laser transmitter 11 is installed on the front side of the scraper blade 2 and is the core component of the slope scanner 1 for emitting a laser beam. The receiver 12 is installed in front of the scraper blade 2. After the receiver 12 receives the information sent back by the laser transmitter 11, it transmits it to the controller 13 to instruct the leveling device to adjust the height and the rotation speed of the soil cutting knife group 3 and the leveling roller group 4 to keep consistent with the laser reference. The controller 13 is installed on the rear side of the laser transmitter 11 and is connected to the receiver 12 and the angle adjuster 22 of the scraper blade 2. According to the information transmitted by the receiver 12, the angle of entry of the scraper blade 2 is automatically adjusted to keep the relative position between the ground and the laser reference unchanged.

[0037] The main function of the soil cutter group 3 is to further break up the larger soil blocks and root stubble in the soil initially operated by the scraper plate 2, so as to ensure that the soil particles are more refined, thereby creating favorable conditions for subsequent leveling and compaction. Figure 1 , Figure 3 and Figure 4As shown, the soil cutting knife group 3 includes a main shaft 32 and a disc blade 31. Both ends of the main shaft 32 are rotatably connected to the frame. The main shaft 32 is arranged in the transverse direction, and a plurality of evenly distributed disc blades 31 are evenly mounted thereon, so that the disc blades 31 are arranged side by side. The disc blade 31 is fixedly connected to the main shaft 32 by a connecting member 33 (such as a bolt).

[0038] The outer circumference of the disc blade 31 is sharpened to form a cutting portion with a conical cross section, which has good cutting and crushing capabilities. The disc blade 31 has a crushing blade 34 inside, which can efficiently cut the soil during the rotation of the disc blade 31 to avoid omissions and overlapping operations. Figure 3 As shown, the crushing blade 34 is a hook-shaped structure. In addition, the crushing blade 34 can also produce a certain soil throwing effect during the rotational movement, evenly distributing the rougher soil blocks to the target area, further optimizing the leveling effect. This part plays a key role in connecting primary leveling and fine leveling, ensuring the uniformity of soil particles and the flatness of the slope.

[0039] The leveling roller group 4 is located at the rear side of the soil cutting knife group 3, and is the key link for further shaping and leveling the soil. Figure 1-Figure 4 As shown, the leveling roller group 4 includes a mounting shaft 43 and a plurality of leveling rollers 42. Both ends of the mounting shaft 43 are rotatably connected to the frame, and the mounting shaft 43 is parallel to the main shaft 32 of the soil cutting knife group 3. The plurality of leveling rollers 42 are arranged in sequence along the mounting shaft 43, that is, the plurality of leveling rollers 42 are arranged side by side. The leveling roller 42 includes a roller body, and a plurality of embossed ridges 41 are evenly distributed along the circumference of the roller body; the embossed ridges 41 of this embodiment are cylindrical protrusions.

[0040] After the soil cutting blade group 3 breaks up the soil and preliminarily distributes the soil, the leveling roller group 4 compacts and levels the soil through its own embossed ridges 41; the cylindrical protrusions help to compact the soil during the rolling process, eliminate the remaining loose soil blocks and small pits, and improve the compactness and surface smoothness of the soil. At the same time, the cylindrical protrusions can effectively guide the slight movement of the soil, ensure that the local high points are leveled, the low-lying areas are filled, and the overall leveling of the slope is achieved.

[0041] In the leveling operation of this embodiment, the slope scanner 1, the scraper blade 2, the soil cutting knife group 3 and the leveling roller group 4 cooperate precisely to complete the soil processing and slope adjustment.

[0042] Embodiment 2:

[0043] This embodiment provides a method for leveling an agricultural micro-slope, using the leveling device described in the first embodiment, and comprising the following steps:

[0044] (1) During operation, the slope scanner 1 scans the ground slope and terrain undulations in real time, collects detailed slope data, and transmits the collected data to the controller 13 to dynamically adjust the angle adjuster 22 of the scraper blade 2.

[0045] (2) The scraper blade 2 performs preliminary tillage and loosening on the soil surface, breaking up larger soil clods to improve the soil structure and lay the foundation for further processing; according to the data from the slope scanner 1, the entry angle of the scraper blade 2 can be adjusted in real time to adapt to different soil conditions and slope requirements.

[0046] (3) The soil cutter group 3 further crushes the processed soil, cuts the soil evenly during rotation, breaks up larger soil clods, and ensures that the soil particles are evenly refined; through precise blade arrangement and rotation, the soil cutter group 3 evenly distributes the refined soil, ready for subsequent compaction and leveling.

[0047] (4) The leveling roller group 4 performs the final compaction and leveling work. The embossed ridges 41 on the roller body roll on the soil surface, compacting and leveling the soil by applying local pressure, eliminating minor surface unevenness. According to the data transmitted in real time by the slope scanner 1, the leveling roller 42 can adjust its working depth and compaction strength to ensure that the final slope meets the design requirements and achieves the expected flatness.

[0048] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
