[0001] The utility model relates to the technical field of mortar pumps, in particular to a buffer mechanism of a mortar pump. Background Art

[0002] A mortar pump is a pump that can adapt to various working conditions, such as conveying acidic and alkaline liquids or slurries, various corrosive slurries in the smelting industry, various dilute acids in the sulfuric acid industry, and various sewage in the environmental protection industry. This pump is both corrosion-resistant and wear-resistant and has a wide range of uses.

[0003] A Chinese patent with publication number CN215486622U discloses a slurry pump casing with sound insulation and shock absorption performance, including a base, a mounting ring, a servo motor, a rotating shaft, and a slurry pump body. The upper surface of the base is fixedly provided with a mounting ring, and the servo motor is fixedly provided inside the mounting ring. The output end of the servo motor is fixedly provided with a rotating shaft, and the slurry pump body is fixedly provided on the right side of the rotating shaft. A support mechanism with a buffering function is installed in the center of the right side surface of the base, and a buffer mechanism is installed on the upper surface of the base; through the setting of the support mechanism and the buffer mechanism, the motor is installed on the rubber block on the support mechanism, so that the rubber block can buffer the bottom of the slurry pump body, and the first arc block on the buffer mechanism buffers the supporting force of the top of the mortar pump, and the two second arc plates buffer the vibration force on the left and right of the slurry pump body to ensure the shock absorption effect of the slurry pump body.

[0004] As mentioned above, the patent provides a slurry pump casing with sound insulation and shock absorption performance. Although it can buffer the vibration force on the left and right sides of the slurry pump body and ensure the shock absorption effect of the slurry pump body, with long-term use, the performance of the corresponding spring will also be affected, and the original buffering effect will be reduced. In severe cases, the buffering effect cannot be achieved, and the adaptability of use needs to be improved. Utility Model Content

[0022] like Figure 1 - Figure 5 As shown, in this embodiment, a buffer mechanism of a mortar pump includes a motor support seat 1, a pump body placement seat 2, an elastic buffer card seat 3 and a buffer assembly, the buffer assembly includes a wedge-shaped block seat 4 and a working pump body 5; the bottom of the wedge-shaped block seat 4 is fixedly connected to the top of the pump body placement seat 2; the surface of the wedge-shaped block seat 4 is slidably connected to a damping rod 6; the end of the damping rod 6 away from the wedge block seat 4 is slidably connected to the surface of the working pump body 5; a damper 7 is sleeved on the surface of the damping rod 6 and located between the wedge block seat 4 and the working pump body 5; the bottom of the working pump body 5 is fixedly connected to a connecting card plate 8; the bottom of the connecting card plate 8 is fixedly connected to It is connected to a threaded screw 9; the bottom end of the threaded screw 9 passes through the pump body placement seat 2 and extends to the bottom of the pump body placement seat 2; the surface of the threaded screw 9 is slidably connected to the surface of the pump body placement seat 2; the end of the threaded screw 9 located at the bottom of the pump body placement seat 2 is threadedly connected to an adjusting nut 10; a limit spring 11 is sleeved on the surface of the threaded screw 9 and located between the bottom of the connecting clamp 8 and the top of the pump body placement seat 2; the top end of the limit spring 11 is fixedly connected to the bottom of the connecting clamp 8; the bottom end of the limit spring 11 is fixedly connected to a sliding snap ring 12; the inner side of the sliding snap ring 12 is slidably connected to the surface of the threaded screw 9.

[0023] Through the above technical solution, the working pump body 5 is first installed, and the connecting clamp 8 is fixed to the bottom of the working pump body 5. Then, the threaded screw 9 of the connecting clamp 8 is passed through the pump body placement seat 2, and at the same time, the damping rod 6 is stuck in the wedge-shaped block seat 4, and the damper 7 is sleeved on the damping rod 6. After the threaded screw 9 passes through the pump body placement seat 2, the working pump body 5 is stuck on the damping rod 6 until the working pump body 5 can resist the damper 7. At this time, the damper 7 is in a compressed state, so that when the working pump body 5 shakes during operation, the damper 7 can buffer the working pump body 5. At the same time, it is necessary to thread the adjusting nut 10 to fix it at the bottom of the pump body placement seat 2 to complete the positioning of the threaded screw 9. When it is used for a long time, the buffering effect of the damper 7 is affected. When the impact is felt, the adjusting nut 10 can be properly continued to be rotated to drive the working pump body 5 to continue to move downward, so that the damper 7 can be in a compressed state again, thereby continuing to achieve the effect of buffering and shock absorption. In addition, a limit spring 11 is sleeved on the surface of the threaded screw 9, and the top of the limit spring 11 is fixed to the connecting clamping plate 8, and the sliding clamping ring 12 is fixed to the bottom end of the limit spring 11. The limit spring 11 is in a compressed state, so that the threaded screw 9 always has an elastic force to slide upward. When the working pump body 5 vibrates, the damper 7 is buffered first, and the limit spring 11 drives the threaded screw 9 to slide up and down for limitation when the working pump body 5 vibrates. The elastic force of the limit spring 11 makes the threaded screw 9 have a buffering effect to a certain extent, further improving the buffering effect.

[0024] like Figure 3 - Figure 5 As shown, the pump body placement seat 2 is fixedly connected to a front connecting baffle 13 on the side facing the motor support seat 1; the motor support seat 1 is fixedly connected to a rear connecting baffle 14 on the side facing the pump body placement seat 2; the surface of the front connecting baffle 13 is fixedly connected to a connecting bolt 15; one end of the connecting bolt 15 passes through the rear connecting baffle 14 and extends to one side of the rear connecting baffle 14; one end of the connecting bolt 15 on one side of the rear connecting baffle 14 is threadedly connected to a fixing nut 16; the number of the wedge-shaped baffles 4 is set to two, and the two wedge-shaped baffles 4 are symmetrically arranged on both sides of the working pump body 5; the surfaces of the two wedge-shaped baffles 4 and the surfaces on both sides of the working pump body 5 are provided with limiting sliding openings 17 adapted to the damping rod 6.

[0025] Through the above technical solution, the pump body placement seat 2 fixes the front connecting baffle 13, and the motor support seat 1 fixes the rear connecting baffle 14. The front connecting baffle 13 and the rear connecting baffle 14 are adapted to each other. The connecting bolts 15 are fixed on the surface of the front connecting baffle 13. The connecting bolts 15 pass through the rear connecting baffle 14 and are fixed by fixing nuts 16, thereby connecting the front connecting baffle 13 and the rear connecting baffle 14, and then fixing the pump body placement seat 2 and the motor support seat 1 together. In addition, two wedge-shaped baffles 4 are provided to buffer and reduce shock on both sides of the working pump body 5. At the same time, limiting slides 17 are opened on both sides of the wedge-shaped baffle 4 and the working pump body 5 for clamping the damping rod 6 to limit the working pump body 5 and ensure stability during operation.

[0026] like Figure 1 and Figure 2 As shown, the bottom of the elastic buffer seat 3 is fixedly connected to the top of the motor support seat 1; the top of the elastic buffer seat 3 is fixedly connected to the motor 18; the output shaft of the motor 18 is fixedly connected to the transmission shaft 19 through a coupling; the end of the transmission shaft 19 away from the motor 18 is rotatably connected to the surface of the working pump body 5; the surface of the transmission shaft 19 is rotatably connected to the protective cover 20; the top of the working pump body 5 is connected to the feed flange pipe 21; the side of the working pump body 5 away from the motor 18 is connected to the discharge flange pipe 22.

[0027] Through the above technical solution, the elastic buffer holder 3 is made of rubber material and has a certain buffering function, which is used to support the installation of the motor 18. When the threaded screw 9 is adjusted, the working pump body 5 may move up and down to a certain extent. At this time, the motor 18 may also need to be consistent with the upper and lower heights of the working pump body 5. Therefore, the elastic buffer holder 3 is set to a rubber material with a buffering function to ensure the consistency of its work. When the motor 18 is working, the output shaft drives the transmission shaft 19 to start rotating, the protective cover 20 protects the transmission shaft 19, and the motor 18 transmits power to the working pump body 5 through the transmission shaft 19, so that it can complete the corresponding conveying work. When it is working, the feed flange pipe 21 is connected to the feed pipe, and the discharge flange pipe 22 is connected to the discharge pipe, thereby completing the overall mortar conveying work.

[0028] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; technologies not described in detail in the present invention are implemented with existing technologies.
