[0023] Example: Reference Figure 1-5A feeding device for chemical raw materials shown in the figure comprises a base plate 1 and a conveyor belt, two fixed blocks 2 are installed on the top of the base plate 1, a motor 3 is installed on the top of one of the fixed blocks 2, movable cavities are opened on the two fixed blocks 2, and screw rods 4 are rotatably installed on the opposite inner walls of the two movable cavities, one end of one of the screw rods 4 is installed on the output shaft of the motor 3, and the two screw rods 4 are installed through a transmission mechanism, and racks 5 are threadedly sleeved on the two screw rods 4, and rotating rods 6 are rotatably installed on the sides of the two fixed blocks 2, one end of the two rotating rods 6 respectively extends into the two movable cavities and is installed with gears 7, and the two gears 7 are respectively meshed with the two racks 5, and the other ends of the two rotating rods 6 are jointly installed with a U-shaped block 8, and the conveyor belt is installed on the opposite inner walls of the U-shaped block 8, and the sides of the U-shaped block 8 away from each other are installed with fixed columns 21, and a supporting mechanism adapted to the fixed columns 21 is provided on the base plate 1.

[0024] With the above structure, when in use, first move the base plate 1 to the specified position, and then start the motor 3. The output of the motor 3 will cause one of the screw rods 4 to rotate, and the rotation of one of the screw rods 4 will cause the other screw rod 4 to rotate through the transmission mechanism. The rotation of the two screw rods 4 will cause the two racks 5 to move, and the movement of the two racks 5 will cause the two gears 7 to rotate. The rotation of the two gears 7 will cause the two rotating rods 6 to rotate. The rotation of the two rotating rods 6 will cause the U-shaped block 8 to rotate. The rotation of the U-shaped block 8 will cause the conveyor belt to rotate. The rotation of the conveyor belt will change the angle, and then the conveying height can be adjusted, so that processing equipment at different heights can be transported, which is convenient for use.

[0025] like Figure 1 , Figure 3 and Figure 5 As shown, the supporting mechanism includes a second motor 12 installed on the side of the base plate 1, a groove is provided on the top of the base plate 1, a threaded rod 13 is installed on the relative inner wall of the groove, one end of the threaded rod 13 is installed on the output shaft of the second motor 12, a T-shaped block 14 is threadedly sleeved on the threaded rod 13, and the sides of the T-shaped block 14 away from each other are installed with U-shaped plates 15, the tops of the two U-shaped plates 15 are provided with mounting holes, telescopic hydraulic cylinders 16 are installed in the two mounting holes, and lifting blocks 17 are installed at the output ends of the two telescopic hydraulic cylinders 16, and the sides of the two lifting blocks 17 are installed with lower supporting plates 18 adapted to the fixed column 21, and the sides of the two lifting blocks 17 are hingedly installed with upper cover plates 19. The advantage of such an arrangement is that the conveying arrangement can be supported by the arrangement of the second motor 12, the threaded rod 13, the T-shaped block 14, the U-shaped plate 15, the telescopic hydraulic cylinder 16, the lifting block 17, the lower supporting plate 18 and the upper cover plate 19.

[0026] Specifically, when the conveyor belt adjusts its angle, the U-shaped block 8 will also move, and the movement of the U-shaped block 8 will cause the fixed column 21 to move. When a certain angle is adjusted, the motor 2 12 is started at this time, and the output of the motor 2 12 will cause the threaded rod 13 to rotate, and the rotation of the threaded rod 13 will cause the T-shaped block 14 to move, and the movement of the T-shaped block 14 will cause the U-shaped plate 15 to move, and the movement of the U-shaped plate 15 will cause the telescopic hydraulic cylinder 16 to move, and the movement of the telescopic hydraulic cylinder 16 will cause the lifting block 17 to move, and the movement of the lifting block 17 will cause the lower support plate 18 and the upper cover plate 19 to move. When the lower support plate 18 is below the fixed column 21, the telescopic hydraulic cylinder 16 is started again, and the output of the telescopic hydraulic cylinder 16 will cause the lifting block 17 to rise and fall, thereby causing the lower support plate 18 to contact the fixed column 21, thereby supporting the conveyor belt to avoid stability being affected due to one end being unsupported.

[0027] like Figure 5 As shown, a limiting rod is installed on the relative inner wall of the groove, a limiting hole is opened on the side of the T-shaped block 14, and the limiting rod passes through the limiting hole. The advantage of this arrangement is that the setting of the limiting rod plays a certain guiding role, so that the T-shaped block 14 moves in the horizontal direction.

[0028] like Figure 3 As shown, a sleeve rod is installed on the side of the lower support plate 18, and a sleeve rope 20 adapted to the sleeve rod is installed on the side of the upper cover plate 19. The advantage of this arrangement is that the arrangement of the sleeve rod and the sleeve rope 20 facilitates the fixed column 21 to provide limited support.

[0029] Specifically, when the lower support plate 18 contacts the fixed column 21, the lower support plate 18 supports the fixed column 21, and then the upper cover plate 19 is rotated to wrap the fixed column 21, and then the rope 20 is put on the sleeve rod, so that the upper cover plate 19 is fixed, thereby providing limited support for the fixed column 21.

[0030] like Figure 5 As shown, the transmission mechanism includes a transmission cavity opened on the base plate 1, the bottom ends of the two screw rods 4 extend into the transmission cavity and are installed with sprockets 9, and the two sprockets 9 are jointly meshed and installed with chains 10. The advantage of this arrangement is that through the arrangement of the sprockets 9 and the chains 10, it is convenient to make the two screw rods 4 rotate at the same time.

[0031] Specifically, when one of the screw rods 4 rotates, one of the sprocket wheels 9 rotates, and the rotation of the sprocket wheel 9 rotates the other sprocket wheel 9 through the chain 10, and the rotation of the other sprocket wheel 9 rotates the other screw rod 4, so that the two screw rods 4 rotate at the same time.

[0032] like Figure 4As shown, guide rods 11 are installed on the relative inner walls of the two movable cavities, and guide holes are opened at the bottoms of the two racks 5. The two guide rods 11 pass through the two guide holes respectively. The advantage of this arrangement is that the guide rods 11 play a certain guiding role, so that the racks 5 move in the horizontal direction.

[0033] like Figure 2 As shown, a PLC controller is installed on the side of one of the fixed blocks 2. The advantage of this arrangement is that the motor 1 3 and the motor 2 12 can be easily controlled through the setting of the PLC controller.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
