[0016] Compared with the prior art, the utility model provides a potash fertilizer bucket wheel gear pump with a sealing structure, which has the following beneficial effects:

[0017] 1. The utility model improves a potash bucket wheel gear pump with a sealing structure. When using the potash bucket wheel gear pump with a sealing structure, first insert the first sealing ring, the second sealing ring and the third sealing ring into the annular placement groove. When the first sealing ring, the second sealing ring and the third sealing ring enter the annular placement groove, the squeezing balls on the left and right sides squeeze the inner wall of the annular placement groove, so that the first sealing ring, the second sealing ring and the third sealing ring are installed inside the oil outlet pipe. Then the gear pump body is installed inside the potash bucket wheel, and then the oil inlet pipe and the oil outlet pipe are connected to the external pipeline. At this time, the gear pump body rotates through the internal main shaft gear and the slave shaft gear. To promote the flow of liquid in the pump chamber. When the main shaft gear rotates, the slave shaft gear will follow the rotation. The liquid is sucked into the compression zone under the meshing action of the slave shaft gear. Since the meshing gap between the main shaft gear and the slave shaft gear is very small, the liquid is compressed and pushed to the compression zone while the slave shaft gear rotates, forming a higher liquid pressure. In the compression zone, when the liquid pressure reaches a certain value, the valve can be opened to let the liquid flow out and continue to flow into the compression zone. The three-layer sealing structure of the first sealing ring, the second sealing ring and the third sealing ring is set to enhance the sealing effect of the oil outlet pipe, and the setting of the extrusion ball enhances the stability of the first sealing ring, the second sealing ring and the third sealing ring.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-4 The potash fertilizer bucket wheel gear pump with a sealing structure shown in the figure, a potash fertilizer bucket wheel gear pump with a sealing structure, comprises a gear pump body 1 and an oil inlet pipe 2 arranged at the front position of the gear pump body 1; a support block 5 is arranged at the right position of the gear pump body 1, a connecting block 6 is arranged at the upper end position of the support block 5, and a mounting pipe 10 is connected to the upper end of the connecting block 6 and located at the right position of the gear pump body 1; a connecting pipe 8 is arranged at the right position of the mounting pipe 10, a connecting plate 9 is arranged at the right position of the connecting pipe 8, and an oil outlet pipe 7 is installed at the right position of the connecting plate 9 A first sealing ring 12, a second sealing ring 13 and a third sealing ring 14 are arranged at the inner side of the oil outlet pipe 7, and placement holes 16 are arranged at the left and right sides of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14, and a squeezing ball 15 is installed at the inner position of the placement hole 16; the sealing effect of the oil outlet pipe 7 is enhanced by the arrangement of the three-layer sealing structure of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14, and the arrangement of the squeezing ball 15 enhances the stability of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, in order to enhance the sealing effect of the oil outlet pipe 7, when using a potash bucket wheel gear pump with a sealing structure, first insert the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 into the annular placement groove 11. When the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 enter the annular placement groove 11, the squeezing balls 15 on the left and right sides squeeze the inner wall of the annular placement groove 11, so that the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 are installed in the oil outlet pipe 7. Then, the gear pump body 1 is installed in the potash bucket wheel, and then the oil inlet pipe 2 and the oil outlet pipe 7 are connected to the external pipeline. At this time, the gear pump body 1 rotates through the internal main shaft gear and the slave shaft gear. The rotation drives the liquid in the pump chamber to flow. When the main shaft gear rotates, the slave shaft gear will rotate accordingly. The liquid is sucked into the compression zone under the meshing action of the slave shaft gear. Since the meshing clearance between the main shaft gear and the slave shaft gear is very small, the liquid is compressed and pushed to the compression zone while the slave shaft gear rotates, forming a higher liquid pressure. In the compression zone, when the liquid pressure reaches a certain value, the valve can be opened to let the liquid flow out and continue to flow into the compression zone. The three-layer sealing structure of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 is set to enhance the sealing effect of the oil outlet pipe 7, and the setting of the squeezing ball 15 enhances the stability of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14.

[0026] An annular placement groove 11 is provided inside the oil outlet pipe 7 and at the outer side of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14. There are three annular placement grooves 11 in total. The distances between the three annular placement grooves 11 are the same. The annular placement groove 11 is a hollow circular ring structure. The annular placement groove 11 is connected to the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 by snapping. The first sealing ring 12, the second sealing ring 13, the third sealing ring 14 and the extrusion ball 15 are all made of rubber material.

[0027] like Figure 2 , Figure 3 and Figure 4As shown, in order to facilitate the placement of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14, when using a potash bucket wheel gear pump with a sealing structure, the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 are first inserted into the annular placement groove 11. When the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 enter the annular placement groove 11, the squeezing balls 15 on the left and right sides will squeeze the inner wall of the annular placement groove 11, so that the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14 are installed inside the oil outlet pipe 7. The setting of the annular placement groove 11 facilitates the placement of the first sealing ring 12, the second sealing ring 13 and the third sealing ring 14, thereby enhancing the sealing of the oil outlet pipe 7.

[0028] A mounting plate 4 is provided at the lower end of the gear pump body 1 and the support block 5. Mounting holes 3 are provided inside the mounting plate 4 and at both sides of the front of the gear pump body 1. The mounting hole 3 is a hollow annular structure. The mounting hole 3 passes through the mounting plate 4. The gear pump body 1 is fixed to the inside of the potash bucket wheel excavator through the mounting plate 4, the mounting hole 3 and the fastening nut. The convenience of installing the gear pump body 1 is improved by the arrangement of the mounting plate 4, the mounting hole 3 and the fastening nut.

[0029] like Figure 1 As shown, in order to improve the convenience of installation of the gear pump body 1, when using a potash bucket wheel gear pump with a sealing structure, the mounting plate 4 is first installed on the lower end of the gear pump body 1, and then the gear pump body 1 is fixed to the inside of the potash bucket wheel through the mounting plate 4 and the fastening nut. The arrangement of the mounting plate 4, the mounting hole 3 and the fastening nut improves the convenience of installation of the gear pump body 1, thereby making the installation and disassembly of the gear pump body 1 more convenient.
