Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a double-furrow plow and tractor. Background Technology

[0002] In areas with irregular landforms, small plots with a certain slope, and densely distributed stones, farmers commonly use plows for tillage. However, the widely used small four-wheel tractors have a significant drawback—the lack of implement suspension systems. This prevents existing conventional plows from functioning properly on these tractors. Therefore, to meet the actual needs of local farmers in this specific agricultural environment, there is an urgent need to develop a mountain plow that can be used independently without a tractor implement suspension system. This would fill the gap in the application of existing agricultural equipment in this environment and provide a more suitable and efficient plowing solution for local agricultural production. Utility Model Content

[0032] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] See Figure 1The double-furrow plow 1 provided in this embodiment of the utility model includes a plow frame 24, a front single-furrow plow assembly 21, and a rear single-furrow plow assembly 23. The front single-furrow plow assembly 21 and the rear single-furrow plow assembly 23 are sequentially arranged on the plow frame 24 along the front-rear extension direction of the double-furrow plow 1. A left suspension ball head 212 is provided on the left side of the plow frame 24, and a right suspension ball head 211 is provided on the right side of the plow frame 24. Both the left suspension ball head 212 and the right suspension ball head 211 are located at the front end of the plow frame 24 and are used to rotate and connect with the power device.

[0034] The double-furrow plow 1 of this utility model can be rotatably connected to a power device such as a small four-wheel tractor by means of a left suspension ball joint 212 and a right suspension ball joint 211, which solves the problem that the plow cannot be used due to the lack of a suspension device on the small four-wheel tractor, and meets the needs of users in the local area.

[0035] In addition, the front and rear single-furrow plow assemblies are arranged sequentially on the plow frame 24 along the front and rear extension direction of the double-furrow plow 1. They can maintain good stability on irregular, small, sloping land with many stones, ensuring smooth plowing operations and improving the quality of cultivation.

[0036] Furthermore, the double-furrow plow 1 is connected to the power unit by the left suspension ball head 212 and the right suspension ball head 211, which gives the double-furrow plow 1 a certain degree of flexibility during operation, enabling it to better adapt to different terrains and operating conditions, and reducing the inconvenience of cultivation caused by land conditions.

[0037] At the same time, this structural design makes the operation of the double-furrow plow relatively simple, allowing users to perform plowing operations more easily, reducing operational difficulty and labor intensity, and improving agricultural production efficiency.

[0038] In some embodiments, the double-furrow plow 1 further includes a depth-limiting wheel assembly 22, which is mounted on the plow frame 24 and located between the front single-furrow plow assembly 21 and the rear single-furrow plow assembly 23. Specifically, the depth-limiting wheel assembly 22 is mounted on the plow frame 24 and positioned between the front and rear single-furrow plow assemblies. During operation, the depth-limiting wheel assembly 22 generates a reaction force upon contact with the ground, providing a stable support point for the plow frame 24. When a tractor pulls the double-furrow plow 1 across irregular, rocky, and complex mountainous terrain, the depth-limiting wheel assembly 22 effectively suppresses the up-and-down and left-and-right swaying of the plow frame 24, making the entire plowing process smoother and more stable. It also ensures good contact between the plowshare and the soil, resulting in more thorough soil tillage, reduced missed tillage, and improved overall tillage efficiency.

[0039] Furthermore, considering the irregular shape, small size, and sloping nature of farmland, the depth-limiting wheel assembly 22 enhances the adaptability of the dual-furrow plow 1 to complex terrain. In small terraced fields or sloping farmland, users can flexibly adjust the depth of the depth-limiting wheel according to the actual terrain and farming requirements, enabling the dual-furrow plow 1 to operate on fields with different slopes and shapes. Whether on gentle or steep slopes, it can precisely control the farming depth, fully tapping the land's potential and meeting diverse local agricultural needs.

[0040] Meanwhile, the well-designed depth limiting wheel assembly 22 acts as a buffer and protector when the plowshare encounters obstacles such as stones. When the front end of the plowshare hits a stone, the depth limiting wheel of the assembly 22 will first contact the stone and displace it, reducing the impact force on the plowshare and minimizing the risk of deformation, wear, or even damage. Simultaneously, the stable tillage condition avoids excessive fatigue caused by frequent up-and-down vibrations of the plowshare, effectively extending the service life of the plowshare and related components, and reducing maintenance costs and replacement frequency for users.

[0041] In some embodiments, the double-furrow plow 1 further includes an adjustment handle 221, which is connected to the depth-limiting wheel assembly 22. The adjustment handle 221 can adjust the height of the depth-limiting wheel. The adjustment handle 221 allows the operator to flexibly and precisely adjust the height of the depth-limiting wheel according to actual farming needs, thereby controlling the depth of the plowshare in the soil. Users can quickly adjust the depth-limiting wheel height directly by adjusting the handle 221 without the need for additional tools or complex procedures. In field operations, this simple operation method greatly saves time and effort, making the plowing process smoother and more efficient, especially when operating on multiple small plots of land requiring frequent changes in tillage depth, significantly improving the overall efficiency of agricultural production.

[0042] In some embodiments, the bottom of the adjusting handle 221 is made into a screw shape and connected to a nut fixed to the depth limiting wheel assembly 22. When the adjusting handle 221 is rotated, due to the action of the thread, the adjusting handle 221 moves along the axis of the nut, thereby driving the depth limiting wheel assembly 22 to move up and down, thus realizing the height adjustment of the depth limiting wheel mounted on the depth limiting wheel assembly 22. Using this simple threaded adjustment structure, the position of the depth limiting wheel is precisely controlled by rotating the handle. Alternatively, in some embodiments, the adjusting handle 221 is connected to a hydraulic valve to control the flow direction and flow rate of hydraulic oil, thereby driving the hydraulic cylinder connected to the depth limiting wheel assembly 22 to extend and retract, realizing the height adjustment of the depth limiting wheel. This adjustment method has the advantages of high adjustment accuracy, large adjustment range, and stepless adjustment capability, but it requires a hydraulic power source and corresponding hydraulic pipeline system. It is suitable for some occasions with high adjustment performance requirements and where the equipment itself has a hydraulic system. Those skilled in the art can select the adjustment method according to the application.

[0043] In some embodiments, the double-furrow plow 1 also includes a lifting cylinder 26, which is mounted on the plow frame 24 and has an oil inlet and an oil outlet. Users can easily raise and lower the double-furrow plow 1 by controlling the oil inlet and outlet of the lifting cylinder 26 via a hydraulic system, without requiring strenuous manual operation or other auxiliary tools. During field transfers or when not in operation, the plow can be quickly raised to avoid unnecessary contact between the plowshare and the ground; when starting work, the plow can be quickly lowered to allow the plowshare to cut into the soil. The entire process is simple, time-saving, and labor-saving, greatly improving work efficiency, especially in small, mountainous fields where frequent start-stop operations are required. Furthermore, raising the plow via the lifting cylinder 26 during non-operational periods or transfers effectively avoids frequent friction and collisions between the plowshare and the ground, reducing wear and deformation of the plowshare, lowering the risk of equipment damage, and thus significantly extending the service life of the plow and reducing equipment replacement costs for users. At the same time, precise lifting control also helps to prevent damage to the plowshare from excessive impact on the soil in the early stages of operation, ensuring the long-term stable operation of the plow.

[0044] In some embodiments, the double-furrow plow 1 includes a lifting cylinder ball joint 27 and a suspension pin 28. The lifting cylinder ball joint 27 is connected to the piston rod of the lifting cylinder 26. The lifting cylinder 26 is connected to a power unit, and the suspension pin 28 connects the lifting cylinder ball joint 27 to the power unit. The lifting cylinder ball joint 27 is fixedly connected to the piston rod of the lifting cylinder 26 and connected to the power unit via the suspension pin 28. This ball joint and pin connection method offers higher flexibility and reliability compared to traditional rigid connections. In complex mountainous operating environments, the connection between the power unit (such as a tractor) and the double-furrow plow 1 via the ball joint and pin effectively buffers vibrations and impacts between them, reducing the adverse effects of uneven road surfaces or bumps during operation on the plow and power unit, ensuring that the plow maintains a stable posture during operation, and improving tillage quality. Furthermore, the design of the lifting cylinder ball joint 27 and the suspension pin 28 allows the double-furrow plow 1 to be quickly and conveniently connected to various types of power units (such as different models of small four-wheel tractors). The universal connection of the ball joint and the flexible fixing method of the pin reduce the special requirements for the power unit connection interface, improving the versatility and adaptability of the double-furrow plow 1. Users can easily install and use the double-furrow plow 1 without making large-scale modifications to the power unit, expanding its market application range and meeting the agricultural needs of more regions and more users. Furthermore, in situations with large variations in land slope and complex terrain, the improved connection method of the hydraulic cylinder ball joint 27 and suspension pin 28 allows the double-furrow plow 1 to better adapt to changes in the power unit's posture on sloping farmland, terraced fields, and other complex terrain conditions, achieving flexible lifting and stable tillage. For example, when working uphill, downhill, or turning, the ball joint connection allows the plow to adjust its posture within a certain range according to the tilt of the power unit, maintaining good contact with the ground, ensuring consistent tillage depth and continuous operation, and improving the double-furrow plow 1's adaptability to complex mountainous terrain. At the same time, the connection design of the ball joint and pin facilitates disassembly and installation, providing convenience for the maintenance and upkeep of the double-furrow plow 1. When the lifting cylinder 26 or related components require repair or replacement, operators can quickly disassemble the connecting parts to perform targeted maintenance without the need for extensive disassembly of the entire plow. This convenient maintenance method not only saves repair time and costs but also improves equipment availability, ensuring that users can complete plowing operations in a timely manner during the busy farming season without missing the planting season.

[0045] In some embodiments, the lifting cylinder 26 is rotatably connected to the frame via a clamp assembly 25, and the lifting cylinder 26 can rotate around the fixed axis of the clamp. This rotatable connection of the clamp assembly 25 provides the lifting cylinder 26 with an angle adjustment capability within a certain range. When it is necessary to control the lifting and lowering of the double-furrow plow 1, the lifting cylinder 26 can flexibly change its angle according to actual operational needs, more precisely adjusting the direction and magnitude of the output force, thereby achieving precise control of the plow's lifting and lowering action. This makes the plow's lifting and lowering more stable and precise in complex terrain, meeting the requirements of fine tillage at different depths and heights.

[0046] Specifically, in uneven working environments such as mountainous terrain, the land slope is varied and undulating. The lifting cylinder 26, which can rotate around the fixed shaft of the clamp, can flexibly adjust its angle according to changes in the tractor's driving posture, maintaining stable support and effective control of the double-furrow plow 1. When the tractor is traveling on slopes or encountering bumps, depressions, or other terrain features, the lifting cylinder 26 can rotate in a timely manner to buffer the impact of terrain changes, reduce the up-and-down swaying and left-and-right swinging of the plow, ensure the smoothness and continuity of the tillage process, and improve the quality of work.

[0047] Furthermore, the structural design of the clamp assembly 25 facilitates the installation, disassembly, and adjustment of the lifting cylinder 26. In practical use, if maintenance, upkeep, or replacement of the lifting cylinder 26 is required, operators can easily remove it using the clamp assembly 25 without the need for complex tools or cumbersome procedures. Simultaneously, the rotatable connection allows the lifting cylinder 26 to better adapt to the installation position and angle requirements of the frame during installation, improving installation convenience and accuracy, reducing errors and adjustment time, and enhancing the user experience.

[0048] In some embodiments, the left and right sides of the front end of the plow frame 24 are respectively connected to left and right front connecting plates 29. Each of the left and right front connecting plates 29 is provided with multiple connecting holes, and an adjustable connecting threaded shaft 210 is inserted into the multiple connecting holes. The left suspension ball head 212 and the right suspension ball head 211 are rotatably connected to the left and right front connecting plates 29 through the adjustable connecting threaded shaft 210.

[0049] See Figures 1 to 3This utility model also provides a tractor, which includes a tractor body 2 and the aforementioned double-furrow plow 1. The tractor body 2 has a left lower lever connecting pin 11 and a right lower lever connecting pin 12. The left suspension ball joint 212 is rotatably connected to the left lower lever connecting pin 11, and the right suspension ball joint 211 is rotatably connected to the right lower lever connecting pin 12. In some embodiments, five evenly distributed connecting holes on the left and right front connecting plates 29, in conjunction with an adjustable connecting threaded shaft 210, provide multiple installation position options for the suspension ball joints. By selecting different connecting holes, the user can precisely adjust the height of the left and right suspension ball joints 211 to achieve a perfect match between the double-furrow plow 1 and the power unit (such as a tractor). This multi-point adjustable design is particularly suitable for mountainous farming environments with complex terrain and frequent changes in altitude, ensuring that the plow maintains the optimal working posture under various operating conditions, improving farming efficiency and quality. The adjustable suspension ball joint height provides the double-furrow plow 1 with great flexibility, meeting the diverse requirements of different crop planting for tillage depth and plow entry angle. For example, when planting root crops, a deeper tillage depth is required. By increasing the height of the suspension ball head, the plowshare can penetrate deeper into the soil. Conversely, when performing surface stubble removal or loosening, lowering the suspension ball head height suffices. This flexible adjustment capability makes the double-furrow plow 1 a multi-purpose agricultural tool, maximizing its effectiveness in various agronomic scenarios. Furthermore, the adjustable rotational connection between the threaded shaft 210 and the front connecting plate 29 reduces additional stress on the plow caused by terrain undulations and vibrations during operation. By appropriately adjusting the height of the suspension ball head, the plowshare can maintain a stable stress state in complex terrain, reducing the risk of wear and fatigue damage at the connection points. Simultaneously, precise attitude control helps reduce collisions between the plowshare and obstacles such as stones and clods of earth, extending the service life of the plowshare and other critical components, and improving the overall reliability and durability of the equipment. Moreover, in the field, users can quickly adjust the height of the suspension ball head according to actual needs without requiring complex tools or specialized skills. This design improves the ease of operation of the equipment, allowing users to flexibly adjust the double-furrow plow 1 according to real-time operating conditions and needs, ensuring smooth operation. Furthermore, the adjustable threaded shaft 210 and connecting hole design facilitate disassembly and maintenance, reducing maintenance costs and time, increasing equipment availability, and ensuring users can efficiently complete plowing operations during busy farming seasons.

[0050] In some embodiments, the tractor body 2 has a traction frame 13, and the double-furrow plow 1 includes a lifting cylinder 26, a lifting cylinder ball joint 27, and a suspension pin 28. The lifting cylinder ball joint 27 is rotatably connected to a hole at the upper end of the traction frame 13 via the suspension pin 28. The lifting cylinder 26 has an oil inlet and an oil outlet, which are respectively connected to the hydraulic output and input interfaces on the tractor. The rotatable connection between the lifting cylinder ball joint 27 and the hole at the upper end of the tractor traction frame 13, in conjunction with the use of the suspension pin 28, provides a stable and reliable connection for the double-furrow plow 1. In complex mountainous operating environments, this connection method can effectively buffer the vibration and impact between the tractor and the plow, reduce plow bumps caused by terrain undulations, ensure that the plow maintains a stable posture during operation, and improve tillage quality. Furthermore, by controlling the oil inlet and outlet of the lifting cylinder 26 through the tractor's hydraulic system, the operator can easily perform the lifting and lowering operation of the double-furrow plow 1 from the cab. This hydraulic control method is not only easy to operate but also allows for precise height adjustment to meet the requirements of different working depths. It is particularly suitable for complex terrains requiring frequent adjustments to the plow height, significantly improving work efficiency. The lifting cylinder ball joint 27 is rotatably connected to the traction frame 13 via the suspension pin 28, enabling the double-furrow plow 1 to adapt to different working conditions and terrain changes. When turning, going uphill or downhill, or passing obstacles, this connection method allows the plow to freely adjust its angle within a certain range, reducing stress on the tractor and plow, and ensuring the continuity and flexibility of operation.

[0051] Furthermore, the hydraulic system enables efficient power transmission between the tractor and the double-furrow plow 1. The inlet and outlet ports of the lifting cylinder 26 are connected to the tractor's hydraulic interface, ensuring smooth hydraulic oil flow, reducing energy loss, and improving the overall system's operational efficiency. This design is particularly suitable for use in agricultural environments requiring high traction and precise control. In emergencies, operators can quickly raise the double-furrow plow 1 via the hydraulic system, preventing violent collisions between the plow and the ground or other obstacles, thus protecting the equipment and operator safety. This rapid-response lifting mechanism is a crucial guarantee for improved operational safety.

[0052] Furthermore, stable connection and hydraulic control reduce unnecessary contact and friction between the plow and the ground, thus reducing plow wear. At the same time, the use of a hydraulic system reduces the complexity of mechanical transmission components, lowers maintenance costs and the risk of equipment failure, and extends the equipment's lifespan.

The lifting cylinder ball joint 27 on the double-furrow plow 1 is rotatably connected to the hole at the upper end of the traction frame 13 on the tractor via the suspension pin 28. Oil holes A and B on the lifting cylinder 26 are respectively connected to the hydraulic output interface on the tractor. By controlling the lifting cylinder 26, the raising and lowering of the double-furrow plow 1 can be controlled.

[0055] The double-furrow plow 1 consists of a front single-furrow plow assembly 21, a depth-limiting wheel assembly 22, and a rear single-furrow plow assembly 23, all fixedly connected to the plow frame 24. The depth-limiting wheel's height is adjusted via an adjusting handle 221.
