[0035] In this embodiment, the temperature control mechanism 5 also includes a motor 503, which is installed in the middle of the top wall of the tank cover 4. The output end of the motor 503 is connected to the main shaft 504, and the bottom end of the main shaft 504 is connected to a rotating plate 505. A sun gear 506 is provided under the rotating plate 505. The rotating plate 505 and the sun gear 506 are connected by multiple connecting shafts 507, and the condenser 501 is connected to the bottom wall of the sun gear 506.

[0036] It should be noted that when the monitored temperature is higher than the standard value, the condenser 501 can be enabled, and the motor 503 can be turned on at the same time to drive the main shaft 504 to rotate, the main shaft 504 drives the rotating plate 505 and the sun gear 506 connected by the connecting shaft 507 to rotate, and the sun gear 506 drives the condenser 501 to rotate, so that the temperature of the inner tank body 3 can be regulated.

[0037] In this embodiment, a plurality of planetary gears 508 are meshed with the outer side of the sun gear 506, an inner gear ring 509 is fixedly provided on the inner wall of the outer tank body 2, and the plurality of planetary gears 508 are all meshed with the inner side of the inner gear ring 509, a connecting rod 510 is connected to the bottom end of the plurality of planetary gears 508, a first bevel gear 511 is connected to the bottom end of the connecting rod 510, a second bevel gear 512 is meshed with the bottom of the first bevel gear 511, and one end of the second bevel gear 512 is connected to one side of the fan blade 502.

[0038] It should be noted that when the sun gear 506 rotates, it also drives the four planetary gears 508 to rotate, the planetary gears 508 drive the connecting rod 510 to rotate, the connecting rod 510 drives the first bevel gear 511 to rotate, the first bevel gear 511 drives the second bevel gear 512 to rotate, and the second bevel gear 512 drives the fan blades 502 to rotate. The rotation of the fan blades 502 can blow cold air onto the condenser 501, and then transmit it to the inner tank body 3, thereby improving the temperature control effect.

[0039] In this embodiment, the protective mechanism includes a buffer pad 7, which is connected to the bottom wall of the outer tank body 2. A connecting groove 101 is symmetrically opened on the inner side of the transport plate 1. Connecting plates 8 are symmetrically connected to the lower part of the two side walls of the outer tank body 2. The connecting plates 8 are located on both sides of the buffer pad 7. The bottom ends of the two connecting plates 8 extend to the corresponding inner sides of the connecting grooves 101 respectively. The connecting plates 8 are slidably connected to the transport plate 1. Buffer components are provided inside the two connecting grooves 101. The buffer components include two rotating shafts 9. The two rotating shafts 9 are both connected to the inside of the connecting grooves 101, and the rotating shafts 9 are located at the bottom of the connecting plates 8. The outsides of the two rotating shafts 9 are fixedly sleeved with movable plates 10. The two movable plates 10 are V-shaped, and the two movable plates 10 are in contact with the connecting plates 8. Springs 11 are provided on the outsides of the two movable plates 10. The outer ends of the two springs 11 extend to both sides of the connecting groove 101 respectively. The springs 11 are connected to the movable plates 10 and the connecting grooves 101 through hinge seats, and the rotating shafts 9 are connected to the inner walls of the connecting grooves 101 through bearings.

[0040] It should be noted that during the transportation and movement of the metering tank, bumps and vibrations will occur due to the uneven road surface, so that the outer tank body 2 will move downward, thereby causing the connecting plate 8 to move downward, thereby increasing the angle between the two movable plates 10 and compressing the spring 11. The buffer pad 7 will also be compressed when the outer tank body 2 moves downward. The design of the buffer pad 7 and the spring 11 can play a role in buffering and absorbing energy, and can avoid direct rigid contact between the outer tank body 2 and the transport plate 1. In this way, the amplitude of the oil shaking inside the tank body can be reduced when the outer tank body 2 is transported and moved, which can improve the stability of the metering tank during transportation and enable it to stabilize more quickly after moving.

[0041] In this embodiment, a detection tube 12 and a feed pipe 13 are vertically connected to the top of the inner tank body 3, respectively. The detection tube 12 and the feed pipe 13 both vertically pass through the rotating plate 505 and the inner side of the tank cover 4. The oil in the feed pipe 13 can enter the interior of the inner tank body 3. Sealing rings are provided on the outer surfaces of the detection tube 12 and the feed pipe 13. A discharge pipe is provided at the bottom of the outer tank body 2, and control valves are provided on the feed pipe 13 and the discharge pipe.

[0042] It should be noted that the detection tube 12 is connected to the controller and can detect the oil output of the metering tank.

[0043] In this embodiment, moving wheels 102 are installed at the four corners of the bottom wall of the transport plate 1, and a push plate 103 is provided on one side of the top wall of the transport plate 1.

[0044] It should be noted that it is convenient to transport and move the metering tank.

[0045] The working principle of the utility model is as follows: the staff opens the tank cover 4, installs the inner tank body 3 inside the outer tank body 2, then covers the tank cover 4, pours the oil into the inner tank body 3 through the feed pipe 13, and finally discharges the oil through the discharge pipe; at this time, the detection tube 12 is connected to the controller to detect the oil output of the metering tank, the temperature control mechanism 5 is arranged inside the outer tank body 2, and the temperature of the inner tank body 3 is monitored in real time through the temperature sensor 6. When the temperature is detected to be higher than the standard value, the condenser 501 can be enabled, and the motor 503 is turned on at the same time to drive the main shaft 504 to rotate, the main shaft 504 drives the rotating plate 505 and the sun gear 506 connected by the connecting shaft 507 to rotate, the sun gear 506 drives the condenser 501 to rotate, and the temperature of the inner tank body 3 can be regulated. The rotation of the sun gear 506 drives the four planetary gears 508 to rotate at the same time, the planetary gear 508 drives the connecting rod 510 to rotate, and the connecting rod 510 drives the connecting rod 510 to rotate. The first bevel gear 511 is driven to rotate, the first bevel gear 511 drives the second bevel gear 512 to rotate, and the second bevel gear 512 drives the fan blade 502 to rotate. The rotation of the fan blade 502 can blow cold air to the condenser tube 501, and then transmit it to the inner tank body 3, thereby improving the temperature regulation effect; during the transportation and movement of the metering tank, bumps and vibrations may occur due to the uneven road surface, so that the outer tank body 2 will move downward, thereby causing the connecting plate 8 to move downward, thereby increasing the angle between the two movable plates 10, and at the same time causing the spring 11 to be compressed, and the buffer pad 7 will also be compressed when the outer tank body 2 moves downward. The design of the buffer pad 7 and the spring 11 can play a role in buffering and absorbing energy, and can avoid direct rigid contact between the outer tank body 2 and the transport plate 1. In this way, when the outer tank body 2 is transported and moved, the amplitude of the oil shaking inside the tank body can be reduced, and the stability of the metering tank during transportation can be improved, so that it can stabilize more quickly after moving.

[0046] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
