[0034] like Figure 1-10 As shown, this embodiment provides a modular hydraulic working machine, tool, and agricultural machine.

[0035] The modular hydraulic working machine includes: a walking chassis 300, the walking chassis 300 is provided with a mounting seat 310, the mounting seat 310 is provided with a first mounting position 311, and the first mounting position 311 is used to switch and install two or more hydraulic tools 500; a hydraulic station 200, the hydraulic station 200 includes a hydraulic pump 210, a hydraulic pipe 220 connected to the hydraulic pump 210, and the hydraulic pipe 220 is provided with a hydraulic joint 230; a power system 100; wherein the walking chassis 300 carries the hydraulic station 200 and the power system 100, the power system 100 is connected to the hydraulic pump 210, and the power system 100 is connected to the walking chassis 300. The first mounting position 311 includes but is not limited to detachable mounting structures such as through holes, screw holes, studs, slots, clamps, slide rails, etc.

[0036] The power system 100 provides power for the hydraulic station 200, provides drive for the traveling chassis 300, enables the traveling chassis 300 to travel, and also provides oil pressure for the hydraulic oil of the hydraulic station 200. The hydraulic station 200 is used to drive the hydraulic equipment carried on the traveling chassis 300, and the hydraulic pipe 220 includes but is not limited to a hydraulic oil supply pipe and a hydraulic oil return pipe. The hydraulic pipe 220 is detachably connected to the hydraulic tool 500 through the hydraulic joint 230, or is detachably connected to other parts requiring hydraulic pressure.

[0037] The hydraulic station 200 is provided with an adapter 240, and the hydraulic connector 230 is installed on the adapter 240. The hydraulic connector 230 is installed on the adapter 240, and the adapter 240 is installed on the walking chassis 300. First, the position of the hydraulic connector 230 is fixed and easy to find. There is no need to find the hydraulic connector 230 in a complex pipeline, which improves the efficiency of replacing the hydraulic tool 500 and avoids wrong removal. Second, the hydraulic connector 230 has a force point, and the hydraulic pipe 220 can be replaced with one hand, which is more convenient to operate. An adapter 240 can be provided with one or more hydraulic connectors 230, which provide hydraulic drive for the hydraulic lifting mechanism 400 and the hydraulic tool 500 respectively. Preferably, the hydraulic connector 230 is a quick connector, and a quick-release adapter is used, so that the hydraulic tool 500 can be quickly replaced.

[0038] The power system 100 includes a power source 110 and a gearbox 120. The hydraulic station 200 is arranged between the power source 110 and the gearbox 120. The output end 111 of the power source is connected to the input shaft 211 of the hydraulic pump, and the input shaft 121 of the gearbox is connected to the input shaft 211 of the hydraulic pump. In this embodiment, the power source 110 is a fossil fuel engine, but it is not limited to this embodiment. The power source 110 can also be a new energy power source 110 or other power sources 110. The output end 111 of the power source is connected to the input shaft 211 of the hydraulic pump, and the input shaft 121 of the gearbox is connected to the input shaft 211 of the hydraulic pump to take power. The gearbox 120 only needs to bear the driving load of the walking chassis 300, and does not need to bear the load of the hydraulic pump 210 and the hydraulic lifting mechanism 400. The volume and weight of the gearbox 120 can be greatly reduced, thereby reducing the volume and weight of the whole machine, which is convenient for transportation with a small vehicle and operation in a narrow ridge. The power source 110, the hydraulic station 200, and the gearbox 120 are arranged in sequence from the front to the rear of the vehicle, and are located in the left and right center of the traveling chassis 300. The mounting seat 310 is arranged at the rear of the vehicle, and the mounting seat 310 is arranged at the rear of the traveling chassis 300. The two sides of the traveling chassis 300 are provided with driving wheels, guide wheels, and tracks 320. The driving wheels and guide wheels tension the tracks 320. The output shaft 122 of the gearbox of the power system 100 is connected to the driving wheels, and the mounting seat 310 is located between the tracks 320 on both sides. The rear part of the traveling chassis 300 is provided with a driving position 600, and the mounting seat 310 is located below or below the driving position 600.

[0039] The mounting seat 310 is detachably mounted with a hydraulic lifting mechanism 400, which includes a first vertical link 410, an upper link 420, a second vertical link 430, and a lower link 440, which are hinged end to end in sequence to form a quadrilateral link. A hydraulic telescopic cylinder 450 is provided on the quadrilateral link, and the hydraulic telescopic cylinder 450 is connected to the hydraulic joint 230. The hydraulic telescopic cylinder 450 is used to drive the quadrilateral link to lift and lower. The first vertical link 410 is detachably mounted on the first mounting position 311, and the second vertical link 430 is provided with a second mounting position 431. The second mounting position 431 includes but is not limited to detachable mounting structures such as through holes, screw holes, studs, slots, clamps, slide rails, etc., as long as the hydraulic tool 500 can be detachably mounted on the second vertical link 430. The hydraulic tool 500 is detachably mounted on the mounting seat 310 through the hydraulic lifting mechanism 400.

[0040] This embodiment includes more than two hydraulic joints 230, and the hydraulic telescopic cylinder 450 of the hydraulic lifting mechanism 400 is connected to some of the hydraulic joints 230, and the number of hydraulic joints 230 is greater than the number required by the hydraulic lifting mechanism 400. The remaining hydraulic pipes 220 can be used to drive the hydraulic tool 500. The hydraulic station 200 not only provides drive for the lifting mechanism, but also provides drive for the hydraulic tool 500. The increase in power does not increase the volume of the hydraulic station 200 much, and the hydraulic transmission only needs to connect the hydraulic pipes 220, and the transmission structure is small in volume. However, for the gearbox 120, the volume will increase significantly with the increase in power, and the mechanical transmission structure is complex and large in volume. The design of the utility model is that the hydraulic station 200 bears the working load and transmission, and the gearbox 120 only needs to bear the walking load and transmission, which can greatly reduce the volume of the whole machine and achieve miniaturization.

[0041] The hydraulic lifting mechanism 400 is also provided with a rotating seat 460, and the first vertical connecting rod 410 is rotatably mounted on the rotating seat 460, and the rotating seat 460 is detachably mounted on the first mounting position 311. The quadrilateral connecting rod can rotate relative to the rotating seat 460 to realize the switching of the left and right positions of the hydraulic tool 500, making its operation mode more flexible. The second vertical connecting rod 430 of the hydraulic lifting mechanism 400 can rise or fall relative to the first vertical connecting rod 410, and the hydraulic lifting mechanism 400 can rotate relative to the mounting seat 310, so that the position of the hydraulic tool 500 can be flexibly changed, and the hydraulic tool 500 can be used to work at different positions, and the versatility is stronger. In particular, in this embodiment, the hydraulic tool 500 is a harvester, and when harvesting high ridge crops, it can harvest between ridges. After harvesting a ridge of crops, turn around and rotate the harvester to the other half of the walking chassis 300. When walking back, the next ridge of crops can be harvested at the same time, and there is no need to return to the origin to continue harvesting.

[0042] In this embodiment, a first assembly hole 314 in the form of a through hole is provided on the mounting base surface 313 (it can also be set as a threaded hole), and multiple first assembly holes 314 are arranged in two rows on both sides of the mounting opening 312. The rotating seat 460 is provided with a mounting plane 462 matching the mounting base surface 313, and the rotating seat 460 is provided with a second assembly hole 463 corresponding to the first assembly hole 314. The mounting plane 462 of the rotating seat 460 is placed against the mounting base surface 313, and bolts are passed through the first assembly hole 314 and the second assembly hole 463 and locked to achieve the installation of the rotating seat 460 on the mounting seat 310.

[0043] The first vertical connecting rod 410 is provided with a first slot 411; the upper connecting rod 420 is provided with a second slot 421; and the rotating seat 460 is provided with a third slot 461. The first slot 411, the second slot 421, and the third slot 461 are used for the hydraulic pipe 220 of the hydraulic station 200, the hydraulic pipe 220 of the hydraulic tool 500, and the line to pass through, so that the pipeline is constrained and will not scatter and cause interference, and provide a certain anti-collision protection for the pipeline, thereby increasing the practical life of the whole machine.

[0044] The first mounting position 311 is provided with a mounting base surface 313. The mounting base surface 313 is provided with a through hole, or a mounting column, or a slot, or a clamp, etc. At present, agricultural machinery installed on a tractor is usually connected by a connecting rod, which is hinged at the end of the connecting rod. It is very difficult to align during hoisting, which seriously affects the efficiency of replacement. Heavier agricultural machinery may even easily cause injury accidents. In the utility model, the mounting base surface is used as a positioning surface for detachable installation. When the hydraulic tool 500 is installed, it is close to the mounting base surface 313 to achieve surface connection. It is easy to position and align during installation, and the replacement efficiency is high.

[0045] The mounting seat 310 is provided with a mounting opening 312, and the hydraulic joint 230 is docked with the mounting opening 312, or the hydraulic pipe 220 passes through the mounting opening 312. The docking of the hydraulic joint 230 with the mounting opening 312 means that the hydraulic pipe 220 is led from the hydraulic station 200 to the vicinity of the mounting opening 312, and the hydraulic joint 230 is near the mounting opening 312. Both sides of the mounting opening 312 can operate the port of the hydraulic pipe 220, and the mounting opening 312 can be used as an operation window. In this embodiment, the side of the mounting seat 310 facing the front of the vehicle is the inward side of the mounting seat 310, and the side of the mounting seat 310 facing the rear of the vehicle is the outward side. The hydraulic pipe 220 is led from the inward side of the mounting seat 310. The user connects the hydraulic joint 230 from the outward side of the mounting seat 310, and can operate the hydraulic joint 230 through the mounting opening 312, which is convenient for operation. In addition, the mounting seat 310 surrounds the hydraulic joint 230, which can also prevent the hydraulic joint 230 from being damaged. It can also be designed that the hydraulic pipe 220 passes through the installation opening 312 and can be led to other places for connection after passing through, so as to avoid the difficulty of connecting the hydraulic pipe 220 caused by the obstruction of the installation seat 310.

[0046] This embodiment is provided with an installation opening 312, a first slot 411, a second slot 421, and a third slot 461 for the hydraulic pipe 220 to pass through, which can both constrain the hydraulic pipe 220 and protect the hydraulic pipe 220; similarly, it can also be provided for other pipes and wires to pass through, avoiding installation and operation difficulties caused by obstruction.

[0047] In this embodiment, the mounting base 313 is basically a plumb plane (agricultural machinery does not require too high precision), which is used to locate the angle of the hydraulic tool 500. For example, for sugarcane that needs to be harvested in the ground, the inclination angle of the blade of the hydraulic tool 500 relative to the horizontal plane is about 5 to 15°, and the mounting base 313 is used to facilitate determination of the inclination angle.

[0048] This embodiment also provides a modular hydraulic tool 500 , which is used to be installed on the first installation position 311 or the second installation position 431 , and the hydraulic tool 500 is used to be detachably connected to the hydraulic joint 230 .

[0049] The present embodiment also provides a modular hydraulic agricultural machine, including the aforementioned working machine and two or more hydraulic tools 500, the hydraulic tool 500 is detachably matched with the first mounting position 311 or the second mounting position 431, and the hydraulic tool 500 is detachably connected with the hydraulic joint 230. In the present embodiment, the first mounting position 311 is installed with a hydraulic lifting mechanism 400, and the hydraulic tool 500 is installed on the second mounting position; Figure 4 As shown, the second mounting position 431 is equipped with an agricultural machine of a harvester; Fig. 9 As shown, the second installation position 431 is equipped with an agricultural machine with a rotary tiller; Fig.10 As shown, the agricultural machine is equipped with a hole punch at the second mounting position 431 .
