The use method and the advantages of the invention are as follows: when the material transportation tank with the adjustable inclination angle for the dry powder is used, the working process is as follows:

install base 2 on haulage vehicle, mounting structure adopts conventional mounting means to install, for example, welding, can dismantle the connection etc. as fig. 1 is jar body 1 horizontality, and pendulum rod 20 is close to the laminating with the both sides of base 2 this moment to lifter 8 whereabouts is on slide 5.

Unloading the dry powder in the tank body 1: work through starter motor 11, make motor 11 drive screw rod 6 rotate, screw rod 6's rotation passes through screw thread transmission, it is close to along the trend support 4 of spout 23 to drive slide 5 and slider 24, thereby make slide 5 drive balladeur train 7 and lifter 8 simultaneously and be close to support 4, and then make ejector pin 14 exert thrust to lifter 8, make lifter 8 drive jar body 1 one end of keeping away from support 4 through layer board 10 and upwards rise, as shown in fig. 2, after the one end that keeps away from support 4 at jar body 1 upwards rises, the dry powder of jar body 1 inside flows to discharge gate 3 under the dead weight effect, thereby make things convenient for unloading of the dry powder of jar body 1 inside, need not to install the fluidized bed additional on the vehicle, reduce vehicle occupation space, consequently, can increase jar body 1's design capacity, improve the conveying efficiency of dry powder.

When the supporting plate 10 supports the tank body 1, the screw 6 drives the sliding frame 7 and the lifting rod 8 to be close to the bracket 4 through the sliding seat 5, so that the lifting angle of the tank body 1 is increased, the height stroke of the sliding frame 7 and the lifting rod 8 is reduced, and the occupied space of the jacking mechanism is reduced.

The lifting rod 8 moves upwards and simultaneously drives the first rotating shaft 12 and the first gear 13 to rotate clockwise through the ejector rod 14, so that the first gear 13 drives the swing rod 20 to expand towards the two sides of the base 2 through the second gear 17 and the second rotating shaft 19, when the tank body 1 is lifted to the maximum inclination angle by the jacking mechanism, the swing rod 20 is perpendicular to the corresponding side edge of the base 2, and the stud 21 is rotated to enable a disc at the lower end of the stud 21 to be in contact with the ground, so that the supporting effect on the tank body 1 is increased, the phenomenon that the gravity center of the tank body 1 is increased after the tank body 1 is lifted to cause instability is avoided, and the stability and the safety.

When the lifting rod 8 jacks up the tank body 1 through the supporting plate 10, the supporting plate 10 slides along the sliding rail 15, the sliding seat 5 drives the piston plate 29 through the pull rod 30 to compress air in a cavity far away from the sliding seat 5 in the air cylinder 16, the conduction direction of the one-way valve I31 points to the air hole 27, and the conduction direction of the two-way valve II 32 points to the cavity, so that the air in the cavity far away from the sliding seat 5 in the air cylinder 16 is blown to a gap between the sliding rail 15 and the sliding groove II 25 through the air pipe 28 and the air hole 27, a dust blowing and cleaning effect is achieved between the sliding rail 15 and the sliding groove II 25, the phenomenon that the supporting plate 10 cannot slide smoothly on the sliding rail 15 due to more accumulated dust is avoided, the friction is reduced by the ball 26 on the sliding rail 15, the smoothness when the tank body 1 is lifted is ensured, and a suction force is generated in the cavity where the pull rod 30 in the air cylinder 16 is located while the piston plate 29 compresses the air in the, since the conducting direction of the check valve three 33 is directed to the air hole 27 and the conducting direction of the check valve four 34 is directed to the cavity, the external air is sucked into the cavity by the suction force.

At the end of the discharge; firstly, the stud 21 is rotated reversely to drive the disc to reset, then the screw 6 is driven to rotate reversely by the starting motor 11, the reverse rotation of the screw 6 drives the slide seat 5 and the slide block 24 to move away from and reset along the moving direction of the sliding groove 23 along the support 4 through the screw transmission, so that the slide seat 5 synchronously drives the slide seat 7 and the lifting rod 8 to move away from and reset towards the support 4, further the ejector rod 14 applies a pulling force to the lifting rod 8, so that the lifting rod 8 drives the end of the tank body 1 away from the support 4 to descend downwards through the supporting plate 10, as shown in figure 1, after the end of the tank body 1 away from the support 4 descends and resets, the tank body 1 is in a horizontal state, the lifting rod 8 falls on the slide seat 5, when the tank body 1 is filled with dry and scattered powder for transportation, because the gravity center of the tank body 1 is lowered, the stability during transportation is improved, and the lifting rod 8 and the slide seat 7, thereby increasing the lateral stability of the tank during transportation of the vehicle.

When the lifting rod 8 and the supporting plate 10 drive the tank body 1 to fall, the screw 6 drives the sliding frame 7 and the lifting rod 8 to be far away from the support 4 through the sliding seat 5, so that the falling speed of the tank body 1 is increased, and the falling efficiency of the tank body 1 is further increased.

The lifting rod 8 moves downwards and simultaneously drives the first rotating shaft 12 and the first gear 13 to rotate anticlockwise through the ejector rod 14, so that the first gear 13 drives the swing rod 20 to be close to and reset to two sides of the base 2 through the second gear 17 and the second rotating shaft 19, the tank body 1 is in a horizontal state in the jacking mechanism, the swing rod 20 is parallel to the corresponding side edge of the base 2, the width of a vehicle is reduced, and the vehicle can conveniently walk.

While the sliding seat 5 is reset, the sliding seat 5 drives the piston plate 29 to compress the air in the cavity of the air cylinder 16 where the pull rod 30 is positioned through the pull rod 30, since the direction of conduction of the check valve three 33 is directed to the air hole 27, the direction of conduction of the check valve four 34 is directed to the cavity, so that the air in the cavity is blown to the gap between the slide rail 15 and the second slide groove 25 through the air pipe 28 and the air hole 27, thereby playing a role of dust blowing and cleaning between the sliding rail 15 and the second sliding chute 25, avoiding unsmooth sliding of the supporting plate 10 on the sliding rail 15 caused by much accumulated dust, the piston plate 29 compresses the air in the cavity of the cylinder 16 in which the pull rod 30 is located while causing a suction force to be generated in the cavity of the cylinder 16 remote from the slide 5, since the opening direction of the first check valve 31 is directed to the air hole 27 and the opening direction of the second check valve 32 is directed to the cavity, the suction force draws the external air into the cavity.
