The hydraulic device can finish the cooling operation of the diesel engine 100 and the cooling oil path 302 through one fan 301, thereby greatly reducing the volume and the weight of the hydraulic device and meeting the requirements of miniaturization and light weight.
As shown in fig. 3 and 4, the output mechanism has a plurality of exporters, wherein the horizontal output mechanism 400 includes: a horizontal base 401, a plurality of horizontal outputs 402, and a plurality of inlet channels 403. The vertical output mechanism 500 includes: a vertical base 501 and a plurality of vertical outputters 502, a plurality of inlet channels 403 are fixed on the horizontal base 401, a plurality of horizontal outputters 402 are horizontally arranged on the horizontal base 401, a plurality of vertical outputters 502 are vertically arranged on the vertical base 501, a plurality of horizontal outputters 402 and a plurality of vertical outputters 502 are respectively communicated with the plurality of inlet channels 403, and oil is supplied to the horizontal outputters 402 or the vertical outputters 502 through the inlet channels 403. The hydraulic device can be more compact in structure by arranging the above-mentioned outputters along the horizontal and vertical directions, thereby avoiding the arrangement of all the outputters in a straight line, and the distribution of oil ways is more reasonable.
As shown in fig. 5, the oil pump 200 is a triple oil pump having two first oil ports 3 and one second oil port 4. The first oil port 3 and the second oil port 4 are respectively provided with a net type oil absorption filter 2 for filtering impurities in the oil path. One of the first oil ports 3 is connected with a walking motor 91 through an output device provided with a one-way valve 6 (model: CCV-16) to control the garlic harvester to walk; the other first oil port 3 is connected with a shovel wheel motor 92 through an output device provided with a one-way valve 6 to control the action of the garlic harvester for shovel up soil; the second oil port 4 is communicated with the total electromagnetic directional valve 10, and a one-way valve 7 (model: CCV-10) is arranged between the second oil port 4 and the total electromagnetic directional valve 10 (model: DSG-02-2D 2-DC). In addition, a first electromagnetic pressure regulating valve 5 (model: SBSG-06) is arranged in the first oil port 3, a second electromagnetic pressure regulating valve 19 (model: SBSG-03) is arranged in the second oil port 4, and pressure gauges 8 are arranged on the first electromagnetic pressure regulating valve 5 and the second electromagnetic pressure regulating valve 19 and used for controlling the output hydraulic pressure.
Specifically, the oil pump 200 is further provided with a liquid level thermometer 1, and the liquid level thermometer 1 comprises a liquid level sensor 17 and a temperature sensor 18 for detecting the liquid level and the temperature in the oil pump 200, so that the liquid level and the temperature can be conveniently maintained in a normal range.
Specifically, the overflow ports of the first electromagnetic pressure regulating valve 5 and the second electromagnetic pressure regulating valve 19 are both communicated with the cooling oil passage 302 of the air cooler 300. The temperature is reduced by the oil passage in the first electromagnetic pressure regulating valve 5 and the second electromagnetic pressure regulating valve 19 by the air cooler 300.
The total electromagnetic directional valve 10 communicates with two driving electromagnetic directional valves 11 (model: DSG-02-2D 2-DC), one first moving electromagnetic directional valve 12a (model: DSG-02-3C 4-DC), and two second electromagnetic directional valves 12b (model: DSG-02-3C 2-DC) at the same time. A driving electromagnetic reversing valve 11 is connected with a conveying hydraulic motor 15 (model: MB 4-50) through an output device provided with a pipe type throttle valve 13 (model: KC-04) for controlling the conveying action of the garlic harvester; the other driving electromagnetic directional valve 11 is connected with a harvesting hydraulic motor 16 (model: MB 4-80) through an output device provided with a pipe type throttle valve 13, and is used for controlling the harvesting action of the garlic harvester. The first moving electromagnetic directional valve 12a is connected with the inclined stay of the garlic harvester through an output device provided with a balance valve 14 (model: HYVBCD 3/8) for controlling the unloading operation of the garlic harvester. A second electromagnetic directional valve 12b is connected with a support rod of the garlic harvester through an output device provided with a tubular throttle valve 13, a superposition type pressure maintaining valve 20 (model: MPC-022) and a synchronous valve 22 (model: DFL-3/8) and is used for controlling the lifting action of the garlic storage box. The other second electromagnetic directional valve 12b is connected with the adjusting rod of the garlic harvester through an output device provided with a pipe type throttle valve 13 and is used for controlling the movement of the garlic storage box to move back and forth.
The pipe type throttle valve 13 can limit the flow of an oil way, prevent the excessive energy consumption and further realize energy conservation and consumption reduction. The balancing valve 14 is used to control the hydraulic balance between the outputs to prevent the diagonal brace from moving too fast and resulting in too fast discharge rates. The stack pressure maintaining valve 20 is used to maintain the hydraulic pressure level, ensuring that there is sufficient support force to resist the weight of the garlic storage tank. The synchronous valve 22 can ensure the movement synchronization of each supporting rod and avoid the inclination of the garlic storage box in the lifting process.
Therefore, the hydraulic device can control the garlic harvester to walk, shovel soil, harvest, transmit and adjust the position of the garlic storage box and discharge, has simple structure, small volume and light weight, and has low energy consumption and low noise in a hydraulic driving mode compared with a mechanical driving mode.
