Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a mountain spring-suspended multi-functional deep tillage plow. Background Technology

[0002] The deep tillage plow is an important piece of tillage equipment. Its main function is to loosen the soil deeply, break up the hard plow pan, improve soil permeability, increase water retention capacity, and thus promote crop root growth.

[0003] As agricultural production expands into mountainous and hilly areas with complex terrain, higher demands are placed on the adaptability of deep tillage plows. These areas have complex underground conditions, with a large number of hard obstacles such as unclogged rocks and tree roots.

[0004] Existing conventional deep tillage plows typically have their plowshares rigidly or semi-rigidly fixed to the frame. This structure is effective on flat terrain with few obstacles. However, when such rigid deep tillage plows operate at high speeds in mountainous and hilly areas, a violent collision between the plowshare and hard underground obstacles can transmit enormous impact force directly to the plowshare, cutterhead, and even the entire frame. This can easily lead to serious damage such as plowshare breakage and frame deformation, forcing work to stop and significantly increasing maintenance costs and equipment failure rates.

[0005] Therefore, this utility model proposes a mountain spring suspension multi-functional deep tillage plow to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a mountain spring-suspended multi-functional deep tillage plow, which aims to improve the existing deep tillage plow's structural rigidity, which makes it prone to damage due to hard collisions when encountering underground obstacles in mountain operations, resulting in low reliability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a mountain spring suspension multi-functional deep tillage plow, comprising a support body, a fixture fixedly connected to the lower part of the support body, a blade holder installed in the fixture, and a plow head rotatably connected to the blade holder via a first fixed column; it also includes a suspension component connecting the support body and the blade holder.

[0008] The suspension assembly includes a main rod, a secondary rod, a spring, a hydraulic rod, and a limit block.

[0009] The upper end of the main rod is rotatably connected to the support body via a first fixed seat and a second fixed column; one end of the auxiliary rod is slidably fitted inside the main rod, and the other end is rotatably connected to the upper part of the tool holder via a second fixed seat and a third fixed column, wherein the second fixed seat is fixedly connected to the tool holder; the spring and the hydraulic rod are both disposed inside the main rod and act together between the main rod and the auxiliary rod to provide a buffer force; to ensure the stability of the telescopic movement, a sliding groove extending along its axial direction is provided on the rod wall of the main rod, and the limiting block is fixedly connected to the auxiliary rod and slidably fitted within the sliding groove.

[0010] Preferably, it further includes a locking assembly for detachably locking the plowshare to the cutter head. More specifically, the plowshare has a groove, the locking assembly is mounted on the cutter head, and includes a housing, a handle, a turntable, a connecting block, and a limiting post. By operating the handle, the limiting post can be selectively inserted into or disengaged from the groove, thereby enabling quick assembly and disassembly of the plowshare.

[0011] Preferably, in the suspension assembly, the spring is sleeved on the outer periphery of the portion of the auxiliary rod that extends into the main rod, and the hydraulic rod is coaxially arranged with the spring.

[0012] Preferably, the mountain spring suspension multi-functional deep tillage plow also includes a traction head, which is fixedly connected to the front end of the support body and is used to connect with external power equipment such as tractors.

[0013] Preferably, it also includes a rotating shaft and wheels. The rotating shaft is horizontally fixedly connected to the main body of the support, and the wheels are rotatably connected to the end of the rotating shaft to support the machine body and enable ground movement.

[0014] Preferably, to enhance the structural strength and rigidity of the support body, the mountain spring suspension multi-functional deep tillage plow also includes a connecting rod, the two ends of which are fixedly connected to the support body to form a stable reinforcing structure.

[0015] Preferably, it also includes a fixing block, bolts, and fixing plates. The fixing block and the fixing plates are fixedly connected by the bolts and are clamped and fixed to the upper part of the support body. It can be used to install counterweights or other auxiliary devices.

[0016] This utility model has the following beneficial effects: 1. In this utility model, a telescopic suspension component with integrated springs and hydraulic rods is set between the main body of the support and the cutter holder. Combined with a plow head that can rotate around the axis, the problem of existing deep tillage plows being prone to hard collisions and damage to the machine when encountering obstacles such as rocks in mountainous operations due to their rigid structure is solved. The plow head can automatically rotate and extend to buffer when it encounters obstacles, effectively protecting the overall structure of the machine, thereby improving the continuity and reliability of the equipment in complex terrain.

[0017] 2. In this utility model, a locking component driven by a handle-controlled linkage mechanism to limit the column is set up. The insertion and removal of the limit column and the groove of the plow head are used to achieve quick locking and releasing. This solves the problem that existing plow heads are mostly fixed with bolts, and the replacement process is cumbersome and time-consuming. It achieves the technical effect of quick disassembly and assembly of the plow head without tools, which greatly simplifies maintenance operations and shortens equipment downtime.

[0020] 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.

[0021] Reference Figures 1-5 The present invention provides an embodiment of a mountain spring-suspended multi-functional deep tillage plow, which aims to solve the problems of existing deep tillage plows used for mountain operations having rigid structures, being easily damaged when encountering obstacles, and having inconvenient plow head maintenance.

[0022] The mountain spring suspension multi-functional deep tillage plow includes a support body 2 that serves as the platform for the entire machine. A retainer 12 is fixedly connected to the lower part of the support body 2. A blade holder 13 is installed inside the retainer 12. The blade holder 13 is used to install tillage components. The plow head 8 is rotatably connected to the blade holder 13 through a first fixed column 14. This connection method provides a basis for the plow head 8 to flip upward when it encounters an obstacle. The plow head 8 also includes a suspension component 3 connected between the support body 2 and the blade holder 13. The suspension component 3 is used to provide retractable elastic buffer and damping when the plow head 8 encounters an obstacle and flips.

[0023] Specifically, the suspension assembly 3 includes a main rod 303. The upper end of the main rod 303 is rotatably connected to the support body 2 through the cooperation of the first fixed seat 301 and the second fixed column 302, so that the suspension assembly 3 can be adjusted by a small range of swing. A sliding groove 307 extending along its axial direction is provided on the rod wall of the main rod 303. The sliding groove 307 is used to guide the linear movement of the internal components. The suspension assembly 3 also includes a second fixed seat 309 fixedly connected to the upper part of the tool holder 13. The second fixed seat 309 serves as a bridge connecting the tool holder 13 and the telescopic mechanism.

[0024] One end of the auxiliary rod 306 is slidably and telescopically fitted inside the main rod 303, while the other end of the auxiliary rod 306 is rotatably connected to the second fixed seat 309 via the third fixed column 310, thereby transmitting the movement of the tool holder 13 to the telescopic mechanism. In order to achieve the buffering function, a spring 304 and a hydraulic rod 305 are provided inside the main rod 303. The spring 304 and the hydraulic rod 305 work together between the main rod 303 and the auxiliary rod 306 to provide elastic buffering and damping. The spring 304 is sleeved on the outer periphery of the part of the auxiliary rod 306 that extends into the main rod 303 to absorb impact energy. The hydraulic rod 305 is coaxially arranged with the spring 304 to provide damping during compression and rebound to prevent severe vibration.

[0025] To ensure that the secondary rod 306 can move stably within the main rod 303, a limiting block 308 is fixedly connected to the secondary rod 306, and the limiting block 308 is slidably fitted within the groove 307 on the main rod 303.

[0026] It also includes a locking assembly 4 for detachably locking the plowshare 8 to the cutter head 13. The locking assembly 4 is mounted on the cutter head 13 and includes a housing 402 and a handle 401 for operation. The housing 402 houses a turntable 403, which is connected to the handle 401 via a fourth fixed post 404, so that the turntable 403 can be rotated when the handle 401 is operated.

[0027] A connecting block 405 is rotatably connected to the turntable 403 via a fifth fixed post 406. A limiting post 407 is fixedly connected to the connecting block 405. The limiting post 407 is the final component for locking. At the same time, a groove 408 is correspondingly provided on the plow head 8 for cooperating with the limiting post 407.

[0028] During assembly and replacement, turning the handle 401 drives the limiting post 407 to move inside the groove 408 through the linkage of the turntable 403 and the connecting block 405. This allows the limiting post 407 to be selectively inserted into the groove 408 to lock the plow head 8, or to be disengaged from the groove 408 to release the plow head 8. This ensures that the process of replacing the plow head 8 does not require additional tools, making the operation convenient and the locking reliable.

[0029] Spring 304 is sleeved on the outer periphery of the part of the auxiliary rod 306 that extends into the main rod 303. Hydraulic rod 305 is coaxially arranged with spring 304. In order to facilitate connection with external power equipment to provide forward power, the mountain spring suspension multi-functional deep tillage plow also includes a traction head 1, which is fixedly connected to the front end of the support body 2.

[0030] To support the device and enable ground movement, the mountain spring suspension multi-functional deep tillage plow also includes a rotating shaft 7 and a wheel 5. The rotating shaft 7 is horizontally fixedly connected to the support body 2, and the wheel 5 is rotatably connected to the end of the rotating shaft 7. To enhance the structural strength and stability of the support body 2, the mountain spring suspension multi-functional deep tillage plow also includes a connecting rod 6, with both ends of the connecting rod 6 fixedly connected to the support body 2.

[0031] To provide additional counterweight or installation platform, the mountain spring suspension multi-functional deep tillage plow also includes a fixing block 9, bolts 10 and fixing plate 11. The fixing block 9 and fixing plate 11 are fixedly connected by bolts 10 and are clamped and fixed to the upper part of the support body 2.

[0032] Working principle: When using the device, the traction head 1 pulls the device, which in turn moves the support body 2 and the rotating shaft 7. The wheels 5 rotate around the axis of the rotating shaft 7, and the device moves on the ground. The connecting rod 6 is placed inside the support body 2 to reinforce it. When the device moves on the ground, the plow 8 loosens the soil. The plow 8 is adjusted by the suspension component 3 to adapt to different terrains. The plow 8 is fixed inside the cutter head 13 by the locking component 4 and then fixed inside the retainer 12 below the support body 2. The fixing block 9 is fixed to the fixing plate 11 by bolts 10 and then fixed above the support body 2.

[0033] When in use, the traction head 1 pulls the device forward, the wheel 5 rotates around the axle 7, and drives the entire support body 2 to move on the ground. At this time, the plow head 8 penetrates into the soil to carry out deep loosening operations. The connecting rod 6 reinforces the support body 2, and the fixing block 9 and fixing plate 11 are stably fixed on the support body 2.

[0034] When the plowshare 8 encounters a hard obstacle such as a rock on the ground, it will flip backward and upward around the axis of the first fixed post 14. This action causes the cutter head 13 to shift. The second fixed seat 309 above the cutter head 13 pushes the auxiliary rod 306 through the third fixed post 310. The auxiliary rod 306 then overcomes the resistance of the spring 304 and the hydraulic rod 305 and slides into the main rod 303. During this process, the spring 304 is compressed to absorb the impact energy, and the hydraulic rod 305 provides damping to achieve smooth buffering. At the same time, the limit block 308 slides inside the slide groove 307 to ensure smooth movement. The entire main rod 303 can also rotate slightly around the second fixed post 302, thereby completing the entire obstacle encounter buffering and avoidance action and effectively protecting the machine.

[0035] When the plowshare 8 needs to be replaced, the operator moves the handle 401 of the locking component 4, causing the turntable 403 to rotate around the fourth fixing post 404 inside the outer casing 402. The turntable 403 drives the connecting block 405 to move through the fifth fixing post 406, thereby driving the limiting post 407 to disengage from the groove 408 of the plowshare 8. At this time, the plowshare 8 can be removed. After replacing it with a new plowshare 8, the handle 401 is turned in the opposite direction, and the limiting post 407 is reinserted into the groove 408, firmly locking the new plowshare 8.
