This pump has the characteristics of small volume, light weight, convenient and flexible installation and use. In the prior art, when the liquid is conveyed into the pump body, because the liquid contains impurities, the impurities enter the pump body together, so that the impurities come into contact with the diaphragm of the pump body, which is likely to affect the diaphragm and is inconvenient to use.

[0003] For example, the patent application number is CN201520934653.7. This utility model discloses a hydraulic high-pressure diaphragm pump. This utility model uses a hydraulic cylinder as the driving component of the diaphragm pump. Due to its large output pressure, in the case of the same caliber, a larger flow rate and a higher lift can be obtained, and it is convenient to maintain. When in use, the liquid contains impurities, so that the impurities enter the pump body together, so that the impurities come into contact with the diaphragm of the pump body, which is likely to affect the diaphragm and is inconvenient to use.

[0004] For example, the patent application number is CN202310473288.3. This invention discloses a diaphragm pump. The diaphragm pump converts the rotation of the motor into a reciprocating motion and drives the diaphragm. The diaphragm pump includes: a partition plate configured to form a pump chamber together with a deformed portion of the diaphragm; a suction passage communicating with the pump chamber via a suction through hole extending through the partition plate; and a suction valve configured to open / close the suction passage. The valve body of the suction valve includes a leakage structure configured to form a passage between the valve body and the seating surface of the partition plate. When in use, the liquid contains impurities, so that the impurities enter the pump body together, so that the impurities come into contact with the diaphragm of the pump body, which is likely to affect the diaphragm and is inconvenient to use. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a hydraulic high-pressure diaphragm pump, which solves the problem that when the liquid contains impurities, the impurities enter the pump body together, so that the impurities come into contact with the diaphragm of the pump body, which is likely to affect the diaphragm and is inconvenient to use.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: a hydraulic high-pressure diaphragm pump, including a pump body, a discharge pipe is arranged on the front of the top of the pump body, and a processing mechanism is arranged on the front of the bottom of the pump body.

A cross plate is arranged inside the moving plate. A motor is arranged above the feed pipe. The end of the output shaft of the motor is provided with a circular plate. A upper gear is arranged on one side of the circular plate. A rotating rod is fixedly arranged at the bottom of the upper gear, and a cross rod is fixedly arranged at the bottom of the rotating rod.

[0008] Preferably, a push plate is arranged on the side of the cross plate away from the cleaning rod. Tooth tracks are arranged on one side of the push plate and the outer side of the circular plate. By combining the tooth tracks with the upper gear or the lower gear, the circular plate can be rotated and the push plate can be moved.

[0009] Preferably, a lower gear is arranged on one side of the push plate, and a connecting rod is arranged on the top of the filter plate.

[0010] Preferably, the bottom end of the connecting rod is movably connected to the feed pipe. The bottom end of the connecting rod is fixedly connected to the collection pipe and the moving plate respectively. By the downward movement of the connecting rod, it can enter the inside of the feed pipe, and the collection pipe and the moving plate can be moved downward simultaneously through the connecting rod, improving the working efficiency.

[0011] Preferably, the cross-sectional shape of the connecting rod is U-shaped, and a connecting spring is arranged on the top of the feed pipe. By the downward movement of the connecting rod, the connecting spring is deformed.

[0014] Beneficial effects

[0015] The utility model provides a hydraulic high-pressure diaphragm pump. Compared with the prior art, the following beneficial effects are achieved:

[0016] 1. The hydraulic high-pressure diaphragm pump rotates the upper gear through the motor, causing the cross rod to rotate and the lower gear to rotate. When the connecting rod moves downward, the collecting pipe and the moving plate move downward simultaneously, with the collecting pipe and the moving plate at different positions of the filter plate. The rotation of the lower gear makes the cleaning rod enter the filter hole. At this time, the collecting pipe is located on one side of the filter hole, preventing impurities from directly falling downward and preventing impurities from affecting the diaphragm in the pump body, facilitating long-term operation.

[0017] 2. In this hydraulic high-pressure diaphragm pump, since the collecting pipe and the moving plate are on the same horizontal line, they can move downward simultaneously, facilitating subsequent impurities to enter the collecting pipe. The downward movement of the connecting rod deforms the connecting spring, enabling the moving plate and the collecting pipe to automatically reset. Description of the Drawings

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution: a hydraulic high-pressure diaphragm pump, including a pump body 1, a discharge pipe 3 is arranged on the front of the top of the pump body 1, and a processing mechanism 2 is arranged on the front of the bottom of the pump body 1.

[0026] The processing mechanism 2 includes a feed pipe 201, a filter plate 202 is arranged inside the feed pipe 201, and a plurality of filter holes 203 are arranged on the surface of the filter plate 202. A collection pipe 204 is arranged on one side of the top of the filter plate 202, and a moving plate 205 is arranged on the other side of the top of the filter plate 202. The moving plate 205 and the collection pipe 204 are both in contact with the filter plate 202. A cleaning rod 206 is arranged inside the moving plate 205, and the cleaning rod 206 is adapted to the filter holes 203. A cross plate 207 is arranged inside the moving plate 205. Above the feed pipe 201, there is a motor 208. The end of the output shaft of the motor 208 is provided with a circular plate 209. A upper gear 210 is arranged on one side of the circular plate 209. A rotating rod 211 is fixedly arranged at the bottom of the upper gear 210, and a cross rod 212 is fixedly arranged at the bottom of the rotating rod 211.

[0027] A push plate 213 is arranged on the side of the cross plate 207 away from the cleaning rod 206. Tooth tracks are arranged on one side of the push plate 213 and on the outside of the circular plate 209.

[0028] A lower gear 214 is arranged on one side of the push plate 213. A connecting rod 215 is arranged on the top of the filter plate 202. Holes are arranged on both the top surface and the bottom surface of the moving plate 205. A plug plate 216 is arranged inside the holes. The plug plate 216 is movably connected to the moving plate 205. The cross rod 212 passes through the plug plate 216 and is in contact with the plug plate 216. The plug plate 216 is movably connected to the inner wall of the moving plate 205.

[0029] Please refer to Figures 1-3 , the bottom end of the connecting rod 215 is movably connected to the feed pipe 201. The bottom end of the connecting rod 215 is fixedly connected to the collection pipe 204 and the moving plate 205 respectively. The cross-sectional shape of the connecting rod 215 is U-shaped. A connecting spring is arranged on the top of the feed pipe 201.

[0030] During operation, materials flow through the feed pipe 201 and enter the inside of the pump body 1. Since the working part of the diaphragm pump mainly consists of a crank-link mechanism, a plunger, a liquid cylinder, a diaphragm, the pump body 1, a suction valve, a discharge valve, etc., the liquid can be discharged through the discharge pipe 3. When the materials enter the feed pipe 201, the filtering work is carried out through the filter holes 203 on the surface of the filter plate 202 inside the feed pipe 201, intercepting the impurities inside to protect the diaphragm inside the pump body 1 and prevent damage to the diaphragm, facilitating long-term use. And an electric motor 208 is used. Since the end of the output shaft of the electric motor 208 is drivingly connected to the circular plate 209, the circular plate 209 is driven to rotate by the electric motor 208, causing the circular plate 209 to rotate on the feed pipe 201 and making the toothed rail at the circular plate 209 rotate simultaneously. Through the continuous rotation of the toothed rail of the circular plate 209, it can mesh with the upper gear 210, causing the upper gear 210 to rotate. Since the upper gear 210 is fixedly connected to the cross rod 212 through the rotating rod 211, the rotating rod 211 and the cross rod 212 rotate simultaneously. When the cross rod 212 rotates, since the cross rod 212 penetrates through the lower gear 214 and the two plug plates 216 at the same time, the rotation of the cross rod 212 causes the plug plates 216 and the lower gear 214 to rotate. When the plug plate 216 rotates, since the plug plate 216 is movably connected to the moving plate 205, the plug plate 216 can prevent materials from entering the inside of the moving plate 205. When the lower gear 214 rotates, since the lower gear 214 meshes with the toothed rail at the push plate 213, the rotation of the lower gear 214 causes the push plate 213 to move, and promotes the movement of the cross plate 207 and the cleaning rod 206, making the movement of the cleaning rod 206 gradually move into the filter holes 203, pushing the impurities in the filter holes 203. Since the collecting pipe 204 and the moving plate 205 are on the same horizontal line, the impurities in the filter holes 203 can enter the collecting pipe 204, preventing the impurities from falling directly downward and preventing the impurities from affecting the diaphragm in the pump body 1, facilitating long-term operation.
