TECHNICAL FIELD

[0001] The present application relates to the technical field of oil tanks, in particular to an easy-to-clean integrated anti-freezing excavator oil tank. BACKGROUND

[0002] Fuel is also prone to freezing in cold weather, causing the vehicle to be unable to travel, especially excavators, as diesel fuel is used in excavators, and the freezing point of diesel fuel is higher than that of gasoline, so it is more prone to freezing.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] Please refer to Figures 1 to 10The application provides a technical scheme: an easy-to-clean integrated anti-freezing excavator oil tank, which comprises an oil tank 01, a mounting cylinder 06 rotatably connected in the oil tank 01, a supporting plate 17 fixedly connected to the mounting cylinder 06, a cleaning plate 16 slidably connected to the supporting plate 17, heat transfer mechanisms arranged on the upper and lower sides of the cleaning plate 16 and the side away from the mounting cylinder 06, the heat transfer mechanisms comprising a partition plate 38 formed in the supporting plate 17, a T-shaped rod 29 slidably connected in the partition plate 38, a guide groove 18 formed in the supporting plate 17, a sliding shaft limitingly connected to the guide groove 18 and arranged on the T-shaped rod 29, an inner cavity 30 formed in the T-shaped rod 29, a cleaning strip 19 fixedly connected to the T-shaped rod 29, a heating strip 26 arranged on the cleaning strip 19, a second communication port 36 formed in the side of the heating strip 26 close to the T-shaped rod 29, a first communication port 35 formed in the T-shaped rod 29 and communicating with the second communication port 36, a communication pipe four 20 communicating with the heating strip 26 of the heat transfer mechanism on the upper side, a second communication sleeve 25 fixedly connected to the mounting cylinder 06 and communicating with a connecting rod 21, a second communication channel 34 formed in the mounting cylinder 06 and communicating with the second communication sleeve 25, a communication pipe five 24 communicating with the heating strip 26 of the heat transfer mechanism on the lower side, a first communication sleeve 23 communicating with the communication pipe five 24 and the second communication channel 34 and arranged on the mounting cylinder 06, a first communication channel 31 formed in the supporting plate 17 and communicating with the partition plate 38, the first communication channel 31 communicating with the mounting cylinder 06, a water supply device arranged on the oil tank 01 and capable of supplying hot water to the mounting cylinder 06, and a driving device arranged on the oil tank 01 and capable of driving the cleaning plate 16 to rotate.

[0030] In work, the fuel supply function can be realized by forming a through hole in the oil tank 01 and connecting with an engine, in heating work, the driving device drives the cleaning plate 16 to rotate, so that the supporting plate 17 and the mounting cylinder 06 rotate at the same time, so as to stir the fuel in the oil tank 01, at the same time, the water supply device supplies hot water to the mounting cylinder 06, so that the hot water flows into the partition plate 38 through the first communication channel 31, then flows into the inner cavity 30 through the T-shaped rod 29, and then flows into the second communication sleeve 25 through the first communication port 35, and then flows into the second communication channel 34 through the second communication sleeve 25, the lower heating strip 26 flows into the first communication sleeve 23 through the communication pipe five 24, and then flows into the second communication channel 34 through the first communication sleeve 23, the heat of the hot water is transferred to the heating strip 26 and the cleaning strip 19, so that the heat is transferred to the fuel in the oil tank 01, thereby reducing the possibility of freezing of the fuel in the oil tank 01;

[0031] Compared with the prior art, since the formation of ice requires the aggregation of condensation nuclei, the rotation of the cleaning plate 16 can continuously stir the inside of the oil tank 01, so that the fuel can continuously flow in the oil tank 01, and therefore, compared with the most partial rectangular shape of the prior art, the cylindrical shape of the oil tank 01 is beneficial to the flow of the fuel, and the flowing fuel is more difficult to form condensation nuclei, thereby improving the anti-freezing effect. In addition, since the heating strip 26 and the cleaning strip 19 are continuously heated, the rotation of the cleaning plate 16 cannot always heat the heating strip 26 and the cleaning strip 19 in one place, so that the heating is uniform, thereby ensuring that the entire oil tank 01 is heated, so that other places are not heated, thereby causing easy freezing. In addition, the cleaning strip 19 does not contact the inner wall of the oil tank 01, so that friction does not occur, thereby avoiding the possibility of flammable heating friction static electricity; in addition, since the oil tank 01 is filled with fuel, when the speed suddenly changes during driving, braking or starting, the fuel will impact the inner wall of the oil tank 01 due to inertia, which may cause the oil tank 01 to deform or even be damaged, and the possibility of internal heating wire impact and damage to cause danger may occur. The oil tank 01 is different from the prior art, and since the array is provided with a plurality of support plates 17 and cleaning plates 16, the oil tank 01 is divided into a plurality of areas, so that the fuel in the oil tank 01 does not directly shake in the oil tank 01, thereby directly reducing the effect of inertia; in addition, since the heating is externally heated by the water supply device, and then heated into the oil tank 01, compared with the prior art of directly heating the heating wire in the oil tank 01, the possibility of ignition due to static electricity or leakage is smaller, and the safety is higher.

[0032] Hot water is supplied to the heating strip 26, so that the heating strip 26 and the cleaning strip 19 can directly heat the fuel, so that the heating temperature is not too high, and the possibility of ignition is reduced. During the heating process, the cleaning plate 16 continuously rotates to stir the oil tank 01, thereby reducing the occurrence of condensation nuclei and further improving the anti-freezing effect, and the heating is more uniform.

[0033] As a further scheme of the present application, the driving device comprises a driving shaft 03 rotatably connected to the oil tank 01. The driving shaft 03 is provided with a lifting groove 32, and further comprises a motor 02 fixedly connected to the oil tank 01. The output shaft of the motor 02 is fixedly connected with a latch shaft 04, and the latch shaft 04 is limitingly and slidably connected with the lifting groove 32. The lower end of the driving shaft 03 is hingedly connected with a connecting rod 21 hingedly connected with the cleaning plate 16.

[0034] When the motor 02 works, the latch shaft 04 is driven to rotate, thereby driving the driving shaft 03 to rotate, thereby driving the connecting rod 21 to drive the cleaning plate 16 to rotate around the axis of the mounting cylinder 06 as the center, thereby driving the mounting cylinder 06 to rotate, thereby realizing the driving function.

[0035] As a further scheme of the present application, the water supply device comprises a rotating shaft 11 fixedly connected to the lower end of the oil tank 01 and the mounting cylinder 06, a communication sleeve three 27 rotatably connected to the outer wall of the rotating shaft 11, a piston cylinder 10 fixedly connected to the lower end of the oil tank 01, a piston 28 limitingly and slidably connected in the piston cylinder 10, a cam 15 fixedly connected to the rotating shaft 11 and capable of driving the piston 28 to move away from the rotating shaft 11, a spring arranged on the piston 28 and capable of resetting the piston 28 to the direction of the cam 15, a communication pipe two 13 communicating with the hot water tank 08 and arranged on the piston cylinder 10, a communication pipe three 14 communicating with the piston cylinder 10 and arranged on the communication sleeve three 27, a one-way valve arranged at the position where the communication pipe two 13 communicates with the piston cylinder 10 and at the position where the piston cylinder 10 communicates with the communication pipe three 14, and a communication pipe one 09 communicating with the hot water tank 08 and arranged on the communication channel two 34.

[0036] may be combined with Figure 3 , Figure 6 and Figure 8 The hot water tank 08 is filled with water, and the hot water in the hot water tank 08 is heated by the heating wire. When the mounting cylinder 06 rotates, the rotating shaft 11 is also driven to rotate, thereby driving the cam 15 to rotate. When the cam 15 rotates to the position of the piston 28, the cam 15 pushes the piston 28 to move into the piston cylinder 10, thereby pushing the hot water in the piston cylinder 10 to flow into the communication sleeve three 27 through the communication pipe three 14, then flow into the rotating shaft 11 through the communication sleeve three 27, and then flow into the communication channel one 31 of the mounting cylinder 06 through the rotating shaft 11, thereby flowing into the inner cavity 30 through the partition plate 38, completing the water supply to the heating strip 26. Then the hot water flows into the communication sleeve two 25 through the communication pipe four 20, and then flows into the communication sleeve one 23 through the communication pipe five 24, and then circulates into the communication channel two 34, and then re-enters the hot water tank 08 through the communication pipe one 09 to be heated, thereby forming a circulating flow of water. The piston 28 is reset by the spring, thereby re-attracting the hot water in the hot water tank 08 into the piston 28.

[0037] Distinguish existing heating method, using external independent heating method, more safe, not easy to cause the oil tank 01 due to overheating and lead to ignition, at the same time not easy to cause the possibility of ignition due to leakage and static electricity; and, through the reciprocating movement of piston 28, hot water can stay in the heating strip 26 and hot water tank 08, and will not continue to flow quickly, circulating and slow hot water heating method, can make the heat through the heating strip 26 to the oil tank 01 inside after, make the cooled hot water back to the hot water tank 08 heating, make the new hot water to heating strip 26 heating, so as to ensure the effective heat transfer, so as to ensure the heating effect, at the same time ensure the water circulation into the hot water tank 08 effectively heated and then flow into the piston 28.

[0038] As a further scheme of the present application, the heat transfer mechanism further comprises a cleaning mechanism, the cleaning mechanism comprising a water jet opening 33 opened on the heating strip 26, the water jet opening 33 is not communicated with the inside of the heating strip 26, the heating strip 26 is limitedly and slidingly connected on the cleaning strip 19, the cleaning strip 19 is provided with a brush on the side away from the supporting plate 17, the cleaning mechanism is provided with a spring below the supporting plate 17, which can make the heating strip 26 reset to the direction away from the installation cylinder 06, the cleaning mechanism is provided with a spring on the side away from the installation cylinder 06, which can make the heating strip 26 on the side reset downward, the heating strip 26 of the cleaning mechanism on the side away from the supporting plate 17 and away from the installation cylinder 06 is communicated with the heating strip 26 of the cleaning mechanism above through the communication pipe 37.

[0039] The working of the bolt shaft 04 can be combined with Figure 2When it is necessary to clean, the fuel tank 01 needs to be emptied at this time, and then the fuel tank 01 starts to rotate clockwise, so that the pin shaft 04 pushes the lifting groove 32 to make the driving shaft 03 move downward. When heating, the pin shaft 04 rotates counterclockwise, so as to pull the driving shaft 03 to rise again. When the driving shaft 03 descends, it pushes the cleaning plate 16 to slide on the supporting plate 17 away from the installation cylinder 06 through the connecting rod 21. At the same time, the cleaning plate 16 pushes the T-shaped rod 29 to rise through the guide rail groove 18, so that the heating strip 26 and the cleaning strip 19 move away from the supporting plate 17. At this time, the upper and lower cleaning strips 19 are attached to the upper and lower inner walls of the fuel tank 01. The cleaning plate 16 drives the cleaning strip 19 away from the supporting plate 17 to be attached to the inner wall of the fuel tank 01. At this time, under the action of the spring on the heating strip 26, the upper and lower heating strips 26 slide away from the installation cylinder 06, so that the water outlet 33 on the heating strip 26 coincides with the communication port one 35 on the T-shaped rod 29, and the communication port two 36 is dislocated from the communication port one 35. Therefore, the water in the inner cavity 30 is directly sprayed through the water outlet 33 without flowing into the heating strip 26. At this time, as the cleaning plate 16 continues to rotate with the installation cylinder 06 as the center, the brushes on the cleaning strip 19 can clean the entire inner wall of the fuel tank 01, and the sprayed water can clean the inner wall of the fuel tank 01. During the cleaning process, the rotation of the installation cylinder 06 can continuously supply water to the piston 28, so that the water outlet 33 sprays water. In order to improve the effect of spraying water, the diameter of the water outlet 33 can be smaller than the diameter of the communication port two 36, or a descaling agent can be added to the hot water tank 08 to improve the cleaning effect. When the cleaning is completed, the pin shaft 04 starts to rotate reversely, so as to pull the driving shaft 03 to drive the connecting rod 21 to rise, so that the cleaning plate 16 starts to reset. When resetting, the left heating strip 26 first pushes the lower heating strip 26 to slide to the right to reset, until it is completely reset. Then the lower heating strip 26 pushes the left heating strip 26 to reset upward, until it is completely reset. The left side starts to push the upper side to reset, so as to complete the reset of all the heating strips 26, that is, the cleaning process is completed.

[0040] The forward and reverse rotation of the pin shaft 04 controlled by the motor 02 can realize the cleaning and heating effect of the heating strip 26, so that the heating and cleaning effects are integrated, the structure is more compact, the cost is lower, the use is more convenient, the water used for heating can be directly used for spraying and cleaning, the cost is lower, the water used for heating can be replaced, the possibility of scale blocking the internal structure is reduced, and the heating effect is guaranteed. At the same time, the cleaning strip 19 can be extended to be attached to the inner wall of the fuel tank 01 to directly scratch and clean the inner wall. The cleaning force of the water outlet 33 is higher, and the fuel tank 01 can be directly and automatically cleaned without opening the fuel tank 01, which is very convenient to use.

[0041] As a further scheme of the present application, the water supply device further comprises an isolation water supply device, which comprises a partition plate 38 fixedly connected in the hot water tank 08, a sliding plate 39 slidably connected in the partition plate 38, and a fixed rod 22 fixedly connected on the piston 28 and fixedly connected with the sliding plate 39.

[0042] The water supply device can be combined with Figure 8 When the water circulates through the communication pipe 09 into the hot water tank 08, it first enters above the partition plate 38 and does not directly fall below the partition plate 38, and only when the piston 28 is pushed by the cam 15 to move towards the hot water tank 08, the sliding plate 39 is driven to retract into the partition plate 38 through the fixed rod 22, so that the water above the partition plate 38 can fall below the partition plate 38, and the sliding plate 39 is intermittently opened, and the water supply is not continuous. The heating wire in the hot water tank 08 is arranged below the partition plate 38.

[0043] Two isolation spaces can be formed above and below, so that the heating wire is isolated in the hot water tank 08, thereby reducing the risk of direct conduction of electricity through the water flow to the inside of the oil tank 01 when a leakage occurs.

[0044] As a further scheme of the present application, the cleaning mechanism further comprises a drainage mechanism, which comprises a push shaft 12 fixedly connected at the lower end of the drive shaft 03 and penetrating through the mounting cylinder 06 and the rotating shaft 11, a support frame 05 fixedly connected at the lower end of the push shaft 12, a plug 07 fixedly connected on the support frame 05, and a slope arranged around the lower surface of the inside of the oil tank 01 and inclined downward to the edge position.

[0045] When the cleaning work starts, the drive shaft 03 descends while pushing the push shaft 12 to descend, so that the push shaft 12 pushes the support frame 05 to slide downward, thereby driving the plug 07 to slide downward, so as to open the plug 07, so that the sewage for cleaning can be discharged from the oil tank 01 through the position of the plug 07, and the slope facilitates the water to be discharged from the plug 07.
