Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a ridge-building machine assembly with hydraulic and mechanical dual-mode pressure regulation. Background Technology

[0002] The ridge-building machine is a key piece of machinery in modern agriculture used to construct field ridges, canal ridges, and terraced field embankments. Through processes such as tilling, soil collection, shaping, and compaction, it can quickly build high-strength, water-resistant field ridges, suitable for various terrains such as paddy fields, dry fields, and orchard terraces.

[0003] Currently, some embankment construction machines use mechanical pressure adjustment mechanisms to control the downward pressure of the forming roller. This type of mechanical pressure adjustment usually involves setting several fixed holes on the frame and using pins inserted into different holes to adjust the working height or inclination angle of the forming roller, thereby changing its compaction degree on the ground. Although this type of mechanical structure has advantages such as low cost, simple structure, and stable working state, its adjustment process requires the operator to get off the machine and complete it manually, which is cumbersome and laborious. It cannot adjust the pressure in real time and flexibly during operation, affecting the work efficiency and ease of use. Utility Model Content

[0004] The purpose of this invention is to provide a dual-mode hydraulic and mechanical pressure regulating assembly for a ridge-building machine, in order to solve the problem in the prior art that when adjusting the pressure of the forming rollers inside the ridge-building machine, mechanical adjustment is required and cannot be flexibly adjusted during operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic and mechanical dual-mode pressure regulating embankment machine assembly, including a frame, a gearbox mounted on the frame, a movably connected protective cover mounted on one side of the frame, a fixedly connected partition plate inside the protective cover, vertically spaced support plates welded to the top of the frame, a movably connected hydraulic adjusting component between two of the support plates, and a hydraulic rod of the hydraulic adjusting component movably connected to the outer wall of the protective cover;

[0006] It also includes a gear reducer, which is installed on the side wall of the partition. The input shaft of the gear reducer is connected to the gearbox. A threaded adjusting rod is provided between the outer wall of the gear reducer and the side wall of the cover. The output shaft of the gear reducer is connected to a cutter disc and a forming roller respectively.

[0007] Furthermore, a traction frame is installed on the top of the frame, the gearbox is installed on the traction frame, a drive shaft is provided between the gearbox and the gear reducer, and universal joints are provided at both ends of the drive shaft, with the two ends of the universal joints respectively connected to the shafts on the gear reducer and the gearbox.

[0008] Furthermore, the hydraulic adjustment component is movably hinged between the two support plates, and the top of the frame and one end near the protective cover are provided with spaced mounting plates. Mounting plates are symmetrically welded to the outer wall of the protective cover. A transverse positioning shaft is provided between mounting plates and mounting plates. The piston rod of the hydraulic adjustment component is movably connected to the positioning shaft.

[0009] Furthermore, the gear reducer adopts a composite reducer body, and the gear reducer has two output shafts. The two output shafts are respectively connected to the cutter disc and the forming roller. The cutter disc and the forming roller are located on both sides of the partition, and the forming roller is located on the side closer to the hydraulic adjustment component.

[0010] Furthermore, the cutter head is provided with spaced soil-taking blades on the side away from the partition. The cross-sectional profile of the soil-taking blades is "L"-shaped. The vertical section of the "L"-shaped soil-taking blade is mounted on the cutter head by fastening screws, and the horizontal section of the "L"-shaped soil-taking blade faces the partition.

[0011] Furthermore, a soil retaining plate is welded to the side wall of the protective cover and located on the gear reducer. The soil retaining plate is located above the forming roller. The forming roller is symmetrically provided with spaced soil pressing discs. The vertical cross-sectional profile of the two soil pressing discs is conical and the ends with the smaller diameter are positioned opposite each other.

[0012] Furthermore, the threaded adjusting rod consists of a threaded rod and a rotating rod. The threaded rod is movably hinged to the side wall of the protective cover, and the other end of the threaded rod extends into the rotating rod and engages with it threadedly. Symmetrical auxiliary plates are provided on the outer wall of the gear reducer, and a linkage column is provided between the two auxiliary plates for rotational connection. One end of the rotating rod is rotatably embedded in the linkage column.

[0013] Compared with existing technologies, this utility model provides a hydraulic and mechanical dual-mode pressure regulating embankment machine assembly. Through a frame, a protective cover is installed on one side of the frame. Inside the protective cover, a partition is installed, and on one side of the partition, a gear reducer is installed. The outer wall of the gear reducer is movably connected to the outer surface of the protective cover via a threaded adjusting rod. A hydraulic adjusting component installed above the frame is also movably connected to the outer wall of the protective cover. When the embankment machine is not working, the height of the protective cover can be adjusted via the hydraulic adjusting component, thereby ultimately changing the position of the cutter head and the forming roller. When the embankment machine is working, the height of the protective cover is adjusted using the hydraulic adjusting component, eliminating the need for the operator to stop the machine and get out for adjustment. This dual-mode hydraulic and mechanical pressure regulation improves the flexibility of adjusting the pressure of the forming roller, further increasing embankment building efficiency.

[0022] As attached Figure 1 To be continued Figure 4 As shown:

[0023] Example 1:

[0024] This utility model provides a ridge-building machine assembly with hydraulic and mechanical dual-mode pressure regulation, including a frame 1, a gearbox 2 mounted on the frame 1, a movably connected protective cover 3 mounted on one side of the frame 1, a fixedly connected partition 4 inside the protective cover 3, vertically spaced support plates 5 welded to the top of the frame 1, a movably connected hydraulic adjustment component 6 between two of the support plates 5, and a hydraulic rod of the hydraulic adjustment component 6 movably connected to the outer wall of the protective cover 3;

[0025] It also includes a gear reducer 7, which is installed on the side wall of the partition 4. The input shaft of the gear reducer 7 is connected to the gearbox 2. A threaded adjusting rod 8 is provided between the outer wall of the gear reducer 7 and the side wall of the protective cover 3. The output shaft of the gear reducer 7 is connected to the cutter disc 9 and the forming roller 10 respectively.

[0026] It should be noted that: a protective cover 3 is installed on one side of the frame 1, a partition 4 is installed inside the protective cover 3, and a gear reducer 7 is installed on one side of the partition 4. The outer wall of the gear reducer 7 is movably connected to the outer surface of the protective cover 3 through a threaded adjusting rod 8. The upper part of the frame 1 is also movably connected to the outer wall of the protective cover 3 through a hydraulic adjusting component 6. When the embankment building machine is not working, the height of the protective cover 3 can be adjusted through the hydraulic adjusting component 6, thereby ultimately changing the position of the cutter head 9 and the forming roller 10. When the embankment building machine is working, the height of the protective cover 3 is adjusted by the hydraulic adjusting component 6, and the operator does not need to stop the machine and get off to adjust it. Through the dual-mode hydraulic and mechanical pressure adjustment, the flexibility of adjusting the pressure of the forming roller 10 is improved, and the embankment building efficiency is further improved.

[0027] The working principle of dual-mode voltage regulation is as follows:

[0028] Hydraulic pressure adjustment mode (for real-time fine adjustment during operation): The oil inlet and outlet of the hydraulic adjustment component 6 are connected to the hydraulic output circuit and multi-way valve on the tractor through high-pressure oil pipes, and the power and control are provided by the tractor's hydraulic system.

[0029] When it is necessary to adjust the pressure of the forming roller 10 in real time according to changes in soil resistance, moisture, and other working conditions, the driver can operate the hydraulic control valve from the tractor cab. Pressurized oil supplied by the hydraulic pump enters the hydraulic adjusting component 6 (hydraulic cylinder), pushing its piston rod to extend or retract. The piston rod, by pushing the positioning shaft 16, forces the protective cover 3 to rotate around its hinge point with the frame 1, thereby changing the overall height of the gear reducer 7, cutter head 9, and forming roller 10. This process achieves stepless, remote, and precise pressure adjustment without stopping the machine, all from inside the cab, ensuring the stability and adaptability of the field ridge quality.

[0030] Mechanical pressure adjustment mode (for pressure locking during long-term operation): After the hydraulic mode adjusts the working height and pressure of the forming roller 10 to the optimal state, mechanical locking can be activated to ensure absolute pressure constancy and prevent pressure drop due to internal leakage that may occur in the hydraulic system during long-term pressure holding. The driver gets off the vehicle and rotates the rotating rod 802 of the threaded adjusting rod 8. Through the threaded pair transmission, the length of the entire adjusting rod is changed and fixed, thereby rigidly supporting the protective cover 3 and the entire working part. At this time, the hydraulic system can be completely unloaded, and the working height of the forming roller 10 is mechanically and rigidly locked by the threaded adjusting rod 8, completely eliminating the risk of pressure drift and ensuring uniform compaction of the field ridges during ultra-long-distance operations.

[0031] The rotating rod 802 is also equipped with a locking nut. When the rotation is adjusted to the required length, tightening the locking nut can prevent the threaded pair from loosening and achieve mechanical locking. Alternatively, the threaded rod 801 and the rotating rod 802 adopt a self-locking trapezoidal thread engagement, relying on the self-locking characteristics of the threaded pair to prevent loosening.

[0032] Mode switching: When switching from mechanical mode back to hydraulic mode, the hydraulic system must first be operated to slightly lift the hydraulic adjusting component 6 to relieve the load on the threaded adjusting rod 8 before the rotating rod 802 can be easily rotated for adjustment or unlocking. The two modes complement each other, balancing ease of operation and reliability.

[0033] In this embodiment: a traction frame 11 is installed on the top of the frame 1, the gearbox 2 is installed on the traction frame 11, a drive shaft 12 is provided between the gearbox 2 and the gear reduction box 7, and universal joints 13 are provided at both ends of the drive shaft 12. The two ends of the universal joints 13 are respectively connected to the shafts on the gear reduction box 7 and the gearbox 2.

[0034] It should be noted that: the traction frame 11 enables efficient connection with power equipment such as tractors, the gearbox 2 transmits power to the drive shaft 12, and the universal joint 13 structure at both ends of the drive shaft 12 can adapt to the power transmission requirements under different working angles, effectively avoiding transmission failure caused by position offset, enhancing the reliability and adaptability of the power system, and ensuring the stable operation of the cutter head 9 and the forming roller 10.

[0035] In this embodiment: the hydraulic adjustment component 6 is movably hinged between the two support plates 5. The top of the frame 1 and one end near the protective cover 3 are provided with spaced mounting plates 14. Mounting plates 15 are symmetrically welded on the outer wall of the protective cover 3. A transverse positioning shaft 16 is provided between the mounting plates 15 and the mounting plates 14. The piston rod of the hydraulic adjustment component 6 is movably connected to the positioning shaft 16.

[0036] It should be noted that the hydraulic adjustment component 6 is installed between the support plates 5 by means of hinge, so that it has the ability to adjust with multiple degrees of freedom. The mounting plate 14 and the mounting plate 2 15 are stably connected by the positioning shaft 16. The piston rod of the hydraulic adjustment component 6 acts on the positioning shaft 16, which can precisely control the lifting and lowering of the protective cover 3.

[0037] This structure improves the stability and mechanical efficiency of hydraulic regulation, while reducing wear on moving parts and extending service life.

[0038] In this embodiment: the gear reducer 7 adopts a composite reducer body. The gear reducer 7 has two output shafts, which are respectively connected to the cutter disc 9 and the forming roller 10. The cutter disc 9 and the forming roller 10 are respectively located on both sides of the partition 4, and the forming roller 10 is located on the side closer to the hydraulic adjustment component 6.

[0039] It should be noted that the composite gearbox has a compact structure and high transmission efficiency. The dual output shafts drive the cutter head 9 and the forming roller 10 respectively, enabling coordinated operation of soil extraction and forming processes. The partition 4 effectively isolates the two working areas, preventing mutual interference. The forming roller 10 is located near the hydraulic adjustment side, facilitating real-time adjustment of compaction pressure, which is beneficial for forming uniform and dense field ridges and improving work quality.

[0040] In this embodiment: the cutter head 9 is provided with spaced soil-taking blades 17 on the side away from the partition plate 4. The cross-sectional profile of the soil-taking blade 17 is "L" shaped. The vertical "L" shaped section of the soil-taking blade 17 is installed on the cutter head 9 by fastening screws, and the horizontal "L" shaped section of the soil-taking blade 17 faces the partition plate 4.

[0041] It should be noted that the "L"-shaped soil-taking blade 17 is fixed by fastening screws, making it easy to install and disassemble, and convenient to replace or maintain. Its unique shape can effectively cut into the soil and lift the soil. The horizontal section guides the soil flow to the forming area towards the partition plate 4, which improves soil-taking efficiency and soil conveying effect, reduces operating resistance, and lowers energy consumption.

[0042] In this embodiment: a soil retaining plate 18 is welded to the side wall of the protective cover 3 and located on the gear reducer 7. The soil retaining plate 18 is located above the forming roller 10. The forming roller 10 is symmetrically provided with spaced soil pressing discs. The vertical cross-sectional profile of the two soil pressing discs is conical and the ends with the smaller diameter are opposite each other.

[0043] It should be noted that the retaining plate 18 effectively prevents soil from splashing and keeps the working environment clean. At the same time, it guides the soil into the area of ​​the forming roller 10. The conical pressing discs are arranged in a relatively opposite manner to form a gradual compaction process, which makes the density in the middle of the field ridge higher than that on both sides, making the structure more stable and less prone to collapse, thus improving the forming quality and durability of the field ridge.

[0044] In this embodiment: the threaded adjusting rod 8 is composed of a threaded rod 801 and a rotating rod 802. The threaded rod 801 is movably hinged to the side wall of the protective cover 3. The other end of the threaded rod 801 extends into the rotating rod 802 and engages with it threadedly. Symmetrical auxiliary plates 19 are provided on the outer wall of the gear reducer 7. A linkage column 20 is provided between the two auxiliary plates 19 for rotational connection. One end of the rotating rod 802 is rotatably embedded in the linkage column 20.

[0045] It should be noted that the threaded adjusting rod 8 constitutes the core of the mechanical pressure regulation. Precise length control is achieved through the threaded engagement of the rotating rod 802 and the threaded rod 801, thereby adjusting the height of the protective cover 3. The hinged design of the linkage column 20 and the auxiliary plate 19 allows for angle self-adaptation within a certain range, ensuring the smoothness and reliability of mechanical adjustment. This structure also provides a reliable mechanical backup for the hydraulic system, ensuring that normal operating pressure can still be maintained in the event of a hydraulic failure, enhancing the safety and practicality of the system.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. 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 above 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.
