Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery, specifically relating to a plowing method for returning straw to the field on sloping hills. Background Technology

[0002] With the improvement of agricultural mechanization and the promotion of green and low-carbon policies, returning straw to the field has become one of the key measures to improve soil, enhance soil fertility, and strengthen sustainability.

[0003] However, the traditional split plow used in plains often has many difficulties on sloping hills. On sloping land or plots with large elevation differences, traditional plows can only turn the soil from high to low, and cannot turn the soil against the slope, resulting in problems such as soil slippage and unstable ridge surface.

[0004] Meanwhile, the existing split plow cannot be used in conjunction with the straw return process; it only serves as a plowing tool.

[0005] Traditional plows are ill-suited to the needs of cultivating land with uneven rainfall distribution and varying soil moisture. For example, on land with different moisture conditions, such as dry land and waterlogged areas, the standard ridge height of existing plows is not conducive to straw decomposition and crop emergence.

[0006] The aforementioned problems place higher demands on the structure and functional adaptability of plows. Therefore, there is an urgent need for a plow that is particularly suitable for straw return operations in areas such as sloping hills. Utility Model Content

[0007] This utility model is designed to solve the problems faced in the above context by dividing the straw return to the field on sloping hills.

[0008] This utility model includes a plow seat, plow handle, plowshare, center dividing plate, soil dividing plate, soil scraper, bottom support rod, soil dividing adjustment support rod, and soil scraper adjustment bracket. The plow seat is fixed to the straw returning machine, the plow handle is fixedly connected to the plow seat by bolts, and the center dividing plate is fixed to the plow handle. The plow seat is connected by bolts, which not only facilitates installation but also makes it easy to disassemble and maintain later. The center dividing plate, fixedly installed on the plow handle, is located directly above the plowshare and is mainly used to evenly divide the turned-up soil layer into two parts, preventing it from piling up to one side or sliding down the slope, thus improving the returning-to-field effect. There are two soil dividing plates, symmetrically arranged on both sides of the plow handle, and both soil dividing plates are hinged to the plow handle. The soil dividing plates are symmetrically installed on both sides of the plow handle, and the angle can be manually finely adjusted according to the terrain and soil tightness through the hinged connection. It can evenly guide the soil separated by the center dividing plate to both sides, forming a neat ridge structure. Two scraper blades are symmetrically mounted on the soil dividing plate and secured with bolts. Located at the rear of the dividing plate, their main function is to level the ridge surface, compact and loosen the soil, and ensure a flat seeding strip for subsequent sowing operations. The scraper blades are bolted in place and can be replaced or have their height adjusted according to different operational needs. In practical use, the scraper blades can also backfill the fertilizer furrows created by the straw returning machine, improving fertilizer utilization. The bottom support rod is horizontally fixed to the plowshare and connects the soil dividing adjustment rod and the scraper adjustment bracket. One end of the soil dividing adjustment rod is movably connected to the dividing plate, and the other end is bolted to the bottom support rod; the soil dividing adjustment rod controls the opening angle of the dividing plate. The scraper adjustment bracket is fixed to the bottom support rod and movably connected to the scraper blade. The scraper adjustment bracket is used to adjust the height of the scraper blade, allowing the ridge height to be flexibly controlled according to terrain and soil moisture. During operation, if the plot is dry, the scraper can be lowered to make the ridge lower and improve drought resistance; while in waterlogged or water-prone areas, the scraper can be raised to increase the ridge and improve waterlogging resistance; it is also more conducive to crop root growth and soil temperature regulation.

[0009] According to the embodiment, the plow seat includes a first fixing plate, a second fixing plate, and a U-bolt. The first fixing plate is fixedly connected to the second fixing plate, and a reinforcing rib is provided at the connection. The U-bolt cooperates with the first fixing plate to make the plow seat detachably connected to the straw returning machine, and it is also convenient to connect and disassemble with different models of straw returning machines, tractors, etc.

[0010] Furthermore, the plowshare is bolted to the plow seat. The plowshare includes a vertical plate and a vertical pin. The bottom of the vertical pin and the vertical plate are fixed to the plowshare, and the upper part of the vertical plate is bolted to the plow seat. The vertical plate has multiple through holes arranged vertically. The vertical plate is the core load-bearing component, connecting the plowshare and the plow seat, responsible for transmitting the traction force of the frame and bearing the resistance to soil turning. The multiple vertically arranged holes allow for height adjustment, and the plowing depth can be changed by adjusting the bolt hole positions to adapt to different operational needs.

[0011] According to the embodiment, the plowshare is fixed to the second fixing plate by bolts. A U-shaped plate is also provided on the upper part of the vertical pin, which tightens the upper part of the vertical pin, thereby improving the bending strength of the plowshare. During continuous operation, the vertical pin is always subjected to a large force, especially when operating on sloping terrain where the forces on both sides are different. The reinforcement of the U-shaped plate can effectively prevent the vertical pin from bending.

[0012] According to an embodiment, the dividing plate is a plate-like structure, fixed to the plow handle and fixedly connected to the plowshare, used to separate the soil from the middle, and then push it to both sides to form a ridge structure. Furthermore, the dividing plate is hinged to a vertical pin, allowing it to rotate around the vertical pin as an axis. The hinged connection between the dividing plate and the plow handle allows for manual adjustment of the opening angle according to the terrain, resulting in neat ridges.

[0013] According to the embodiment, each soil dividing plate is equipped with a U-shaped rod on the back of the dividing plate, i.e., the side facing the plow handle, for use with the soil dividing adjustment support rod. The dividing plate has multiple through holes arranged vertically for bolting to secure the scraper blade. The U-shaped rod on the back of the dividing plate, in conjunction with the soil dividing adjustment support rod, facilitates adjustment of the dividing plate's opening angle, allowing for flexible control of the ridge shape according to actual plot conditions. The multiple vertical holes distributed on the plate also facilitate quick adjustment of the scraper blade's installation height.

[0014] According to an embodiment, the scraper blade is fixed to the rear end of the dividing plate by bolts. The front end of the scraper blade has multiple through holes arranged vertically for connection with the dividing plate via bolts. The scraper blade can be set at different heights. This adjustable scraper blade design allows for flexible adjustment of the ridge height. The height of the scraper blade can be adjusted to create low ridges in arid areas to enhance drought resistance, or to raise it in waterlogged areas to improve drainage and ventilation, enabling mechanized operations more suited to the terrain and soil moisture conditions.

[0015] Furthermore, there are two soil-dividing adjustment supports, each with multiple through holes. These holes are used to adjust the opening angle of the soil-dividing plate, facilitating quick manual adjustments based on terrain conditions.

[0016] According to an embodiment, the scraper adjustment bracket includes two threaded support rods, two mating support rods, and a vertical rod. The threaded support rods are threaded, with one end movably connected to the scraper blade, and the other end threadedly mating with one end of the mating support rod. The mating support rod has an opening at its end away from the threaded support rod, through which the vertical rod passes. At least two nuts on the vertical rod engage with each other to clamp the mating threaded rod. The angle of the scraper blade can be adjusted slightly by adjusting the threaded support rods and the mating support rods, and the height of the scraper blade can be adjusted by the nuts on the vertical rod.

[0017] The beneficial effects of this utility model are as follows:

[0018] This split-plate structure breaks the limitations of traditional plows, enabling reverse slope turning and turning soil from the bottom to the top of the slope on sloping land. Through the interception of the split plate and the soil turning mechanism of the split plate, the direction of the soil is controlled, which not only improves the flexibility of operation, but also reduces soil slippage caused by the slope.

[0019] The adjustable height design of the scraper allows the ridge height to be flexibly adjusted according to the specific conditions of the plot. In arid areas, low ridges help retain moisture; in waterlogged areas, high ridges facilitate drainage and warming, ensuring that crop roots are in a suitable growth environment and enhancing disaster resistance.

[0020] The scraper blade, when used in conjunction with the straw return machine, can also backfill the fertilizer trenches created by the straw return machine, thereby improving fertilizer utilization.

[0021] The soil-separating adjustment rod and the soil-scraping adjustment bracket can quickly adjust the plowing depth, soil-separating angle, and ridge width and height, making them suitable for different crop operation needs. At the same time, they maintain consistent operation results when dealing with different terrain and slope changes. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 In this embodiment, the straw return to the field on sloping hills is divided into plows, including a plow seat 1, a plow rod 2, a plowshare 3, a middle dividing plate 4, a soil dividing plate 5, a soil scraping plate 6, a bottom support rod 7, a soil dividing adjustment support rod 8, and a soil scraping adjustment bracket 9; the plowshare 3 penetrates deep into the soil layer and turns over the soil.

[0029] The plow seat 1 is fixed to the straw returning machine, and the plow rod 2 is fixedly connected to the plow seat 1 by bolts. The center dividing plate 4 is fixed to the plow rod 2. The plow seat 1 is connected by bolts, which not only facilitates installation but also makes it easy to disassemble and maintain later. The plow rod 2 is firmly connected to the frame of the returning machine through the plow seat 1 and is used to transmit traction force. The center dividing plate 4, which is fixedly installed on the plow rod 2, is located directly above the plowshare 3 and is mainly used to evenly divide the turned-up soil layer into two parts, preventing it from piling up to one side or sliding down the slope, thus improving the returning effect.

[0030] The plow seat 1 includes a first fixing plate 11, a second fixing plate 12, and a U-bolt 13. The first fixing plate 11 and the second fixing plate 12 are fixedly connected, and a reinforcing rib is provided at the connection point. The U-bolt 13 cooperates with the first fixing plate 11 to allow the plow seat 1 to be detachably connected to the straw returning machine. The U-bolt 13 and the reinforcing rib ensure strength while also facilitating connection and disassembly with different models of straw returning machines, tractors, etc. The reinforcing rib improves the overall rigidity of the plow, making it more impact-resistant when working on slopes and ensuring operational stability.

[0031] The central dividing plate 4 is a plate-like structure, fixed to the plow handle 2 and connected to the plowshare 3. It is used to separate the soil in the middle, and then the soil-separating plate 5 pushes it to both sides to form a ridge structure. The central dividing plate 4 is a core innovative structure that distinguishes it from traditional plows. Located above the plowshare 3 and in front of the soil-separating plate 5, it can separate the turned-up soil to the left and right along the central axis. This structure is extremely advantageous when working on slopes, effectively preventing the soil from sliding downhill due to gravity and ensuring flexibility in the working direction. After the soil is turned up, it no longer falls directly to one side, but is intercepted by the central dividing plate 4 and guided to both sides, realizing upward turning of soil under sloping conditions.

[0032] The plowshare 2 is bolted to the plow seat 1. The plowshare 2 includes a vertical plate 21 and a vertical pin 22. The bottom of the vertical pin 22 and the vertical plate 21 are fixed to the plowshare 3, and the upper part of the vertical plate 21 is bolted to the plow seat 1. The vertical plate 21 has multiple through holes arranged vertically. The vertical plate 21 is the core load-bearing component, connecting the plowshare 3 and the plow seat 1, responsible for transmitting the traction force of the frame and bearing the resistance to soil turning. The multiple vertically arranged holes allow for height adjustment, and the plowing depth can be changed by adjusting the mounting hole positions to adapt to different operational needs.

[0033] The plowshare 2 is fixed to the second fixing plate 12 by bolts. A U-shaped plate is also provided on the upper part of the vertical pin 22. The U-shaped plate tightens the upper part of the vertical pin 22, which improves the bending strength of the plowshare 2. During continuous operation, the vertical pin 22 is always subjected to a large force, especially when working on slopes and hills where the forces on both sides are different. The reinforcement of the U-shaped plate can effectively prevent the vertical pin 22 from bending.

[0034] There are two soil dividing plates 5, symmetrically arranged on both sides of the plow handle 2, and each soil dividing plate 5 is hinged to the plow handle 2. The soil dividing plates 5 are symmetrically installed on both sides of the plow handle 2, and the hinged connection allows for manual fine-tuning of the angle according to the terrain and soil tightness. Even on sloping land or plots with uneven soil, the continuity and balance of tilling can be maintained. The soil dividing plates 5 can evenly guide the soil separated by the central dividing plate 4 to both sides, forming a neat ridge structure.

[0035] Furthermore, the soil dividing plate 5 is hinged to the vertical pin 22, allowing it to rotate around the vertical pin 22 as an axis. The soil dividing plate 5 is connected to the plow rod 2 via a hinged structure, allowing manual adjustment of the opening angle according to the terrain to form neat ridges. Each soil dividing plate 5 is equipped with a U-shaped rod, located on the back of the soil dividing plate 5, facing the plow rod 2, for use with the soil dividing adjustment support rod 8. The soil dividing plate 5 has multiple through holes arranged vertically for use with bolts to fix the scraper plate 6.

[0036] The U-shaped rod on the back of the soil dividing plate 5, in conjunction with the soil dividing adjustment support rod 8, facilitates the adjustment of the opening angle of the soil dividing plate 5, allowing for flexible control of the ridge shape according to actual plot conditions. Multiple vertical holes distributed on the plate also facilitate quick adjustment of the installation height of the scraper blade 6.

[0037] Two scraper blades 6 are symmetrically mounted on the soil dividing plate 5, secured with bolts. Located at the rear of the dividing plate 5, the scraper blades 6 primarily function to level the ridge surface, compact and loosen the soil, ensuring a flat seeding strip for subsequent sowing operations. The scraper blades 6 are bolted in place and can be replaced or have their height adjusted according to different operational needs. In actual use, the scraper blades 6 scrape excess soil to both sides, enabling backfilling of the fertilizer trenches in the straw returning machine and improving fertilizer utilization.

[0038] Furthermore, the scraper blade 6 is fixed to the rear end of the dividing plate 5 by bolts. The front end of the scraper blade 6 has multiple through holes arranged vertically for connection with the dividing plate 5 using bolts. The scraper blade 6 can be set at different heights. This adjustable scraper blade 6 design allows for flexible adjustment of the ridge height. The height of the scraper blade 6 can be adjusted to create low ridges in arid areas to enhance drought resistance, or to raise it in waterlogged areas to aid drainage and ventilation, enabling mechanized operations more suited to the terrain and soil moisture conditions.

[0039] The bottom support rod 7 is horizontally fixed to the plowshare 3 and is used to connect the soil-dividing adjustment rod 8 and the soil-scraping adjustment bracket 9. One end of the soil-dividing adjustment rod 8 is movably connected to the soil-dividing plate 5, and the other end is fixed to the bottom support rod 7 by bolts. The soil-dividing adjustment rod 8 is used to control the opening angle of the soil-dividing plate 5. One end is movably connected to the soil-dividing plate 5, and the other end is fixed to the bottom support rod 7 by bolts. The movable connection by bolts allows the soil-dividing plate 5 to be flexibly adjusted according to different slopes or soil conditions, ensuring the efficient operation of the fertilization machine.

[0040] Furthermore, there are two soil-dividing adjustment supports 8, each with multiple through holes. These holes are used to adjust the opening angle of the soil-dividing plate 5, facilitating quick manual adjustments based on terrain conditions.

[0041] The soil scraper adjustment bracket 9 is fixed to the bottom support rod 7 and is movably connected to the soil scraper 6. The soil scraper adjustment bracket 9 is used to adjust the height of the soil scraper 6, so that the height of the ridge can be flexibly controlled according to the terrain and soil moisture. During operation, if the plot is dry, the soil scraper 6 can be lowered to make the ridge lower and improve drought resistance; while in waterlogged or easily waterlogged areas, the soil scraper can be raised to raise the ridge and improve waterlogging resistance; it is also more conducive to crop root growth and soil temperature regulation.

[0042] Furthermore, the scraper adjustment bracket 9 includes two threaded support rods 91, two mating support rods 92, and a vertical rod 93. The threaded support rods 91 are threaded, with one end movably connected to the scraper blade 6, and the other end threadedly mating with one end of the mating support rod 92. The mating support rod 92 has an opening at its end away from the threaded support rod 91, through which the vertical rod 93 passes. At least two nuts on the vertical rod 93 engage with each other to clamp the mating threaded rod. The angle of the scraper blade 6 can be slightly adjusted by adjusting the threaded support rods 91 and the mating support rods 92, and the height of the scraper blade 6 can be adjusted by the nuts on the vertical rod 93.

[0043] During operation, the centrally positioned plow is suspended on the crossbeam of the straw returning machine. The plowshare 3 first cuts into the soil layer, turning it up. After the soil is lifted, the central dividing plate 4 splits the turned-up soil from the center line, preventing it from sliding downhill and guiding it to both sides. Subsequently, the soil dividing plates 5 distributed on both sides of the plow handle 2 further push the soil to the sides. The rear-mounted scraper 6 scrapes and shapes the soil as it passes over it. The scraper 6 is adjustable in height according to different terrains, forming low ridges to retain moisture in dry land and high ridges to facilitate drainage in waterlogged areas. To meet different needs, the soil dividing plate 5 and the scraper 6 are adjusted by adjusting the soil dividing adjustment support rod 8 and the scraper adjustment bracket 9.
