Description

Technical Field

[0001] The utility model relates to the technical field of slurry pumps, in particular to a novel pump head structure for a slurry pump. Background Art

[0002] The new pump head structure of the slurry pump is mainly used for connecting the output port of the slurry pump. For example, according to the requirements of the construction project, the new pump head structure of the slurry pump replaces manual labor, which can effectively improve work efficiency and reduce labor intensity. For example:

[0003] Announcement No. CN214063395U provides a pump head structure of a slurry pump, which belongs to the field of slurry pumps, including a pump casing, a connecting pipe fixedly connected to the left side of the pump casing, a flange fixedly connected to the left side of the connecting pipe, and a reinforcing rib fixedly connected to the outside of the connecting pipe. The left side of the inner part of the connecting pipe is connected to a threaded sleeve by a threaded rotation, an annular plate fixedly connected to the left side of the threaded sleeve, and a spring fixedly connected to the left side of the annular plate. The threaded sleeve is connected to the inner part of the connecting pipe by a threaded rotation, which facilitates the fixing of the annular plate, the annular sleeve and the sealing ring, and facilitates the fixed installation of the sealing ring in the flange to avoid falling, detaching and losing, and is convenient for removing and replacing the sealing ring. At the same time, the sealing ring is squeezed by the spring to increase the sealing effect of the connection between the flange and the external connection object to avoid water leakage from the connection between the two. At the same time, the stability of the pump casing and the stability of the flange connection are increased by the separate arrangement of the support ring, support rod, reinforcement sleeve and reinforcement rib.

[0004] However, some current slurry pumps' new pump head structures generally cannot be quickly replaced and installed during operation, which greatly reduces the transportation effect. In addition, the wear of the pump head by the material cannot be reduced during operation, making it inconvenient to use and of low practicality. Therefore, the present invention provides a photovoltaic bracket steel adjustable base to solve the above-mentioned problems.

[0005] Therefore, those skilled in the art are in urgent need of designing a slurry pump that can be rotatably inserted. Utility Model Content

[0008] (2) Technical solution

[0009] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

The "first", "second", etc. in the following are distinguished for the description and have no other special meanings.

[0031] In view of the problems existing in the prior art, the present invention provides a new pump head structure for a slurry pump. The slurry pump comprises a slurry pump body and a pump head connected to the left side of the slurry pump body. The specific description is as follows:

[0032] 1-Slurry pump body

[0033] A first feed pipe is installed in the middle of the slurry pump body, and a mounting plate is provided on the left side of the first feed pipe. A first limiting rod is inserted into the interior of the mounting plate, and a material separation rubber pad is provided on the outside of the first limiting rod. A positioning block is installed on the left side of the slurry pump body, and a connecting assembly is installed on the upper side of the slurry pump body. The connecting assembly consists of a handheld rod, a first connecting plate, a second connecting plate, a connecting rod, and a limiting block. The mounting plate and the first feed pipe are initially connected to the interior of the connecting groove through the first limiting rod. At this time, a material separation rubber pad is provided between the mounting plate and the pump head, and the limiting block is engaged with the slurry pump body, thereby achieving a certain degree of leak prevention and quick installation effect.

[0034] In some examples, the mounting plate is positioned at an equal angle to the left side of the first feed pipe, and the first stopper is threadedly connected to both the mounting plate and the pump head. By rotating the first stopper, the mounting plate and the pump head are connected in series, thereby completing the initial connection between the first feed pipe and the pump head.

[0035] In some examples, the rubber spacer is slidably connected to the pump head, and the longitudinal cross-section of the rubber spacer is T-shaped. The rubber spacer is placed inside the connecting groove along the pump head, and the first feed pipe is connected to the pump head, thereby preventing material leakage.

[0036] In some examples, a handle is mounted on the upper side of the pump head, and a first connection plate is connected to the right side of the handle. A second connection plate is mounted on the right end of the first connection plate, and a connecting rod is connected to the lower side of the second connection plate. A limit block is mounted on the lower end of the connecting rod. Through the connection effect between multiple parts, a quick connection between the slurry pump body and the pump head is completed.

[0037] In some examples, the connecting rod is threadedly connected to the stop block, and the stop block is engaged with the slurry pump body. The connecting rod pushes the stop block downward, and the stop block slides into the interior of the slurry pump body and engages with the slurry pump body, thereby completing the positional fixation of the slurry pump body.

[0038] 2-First feed pipe

[0039] The pump head has a retention tank inside and a connection tank on the right side. An insulating layer is installed inside the retention tank, and a mounting block is installed outside the insulating layer. A second limiting rod is installed inside the mounting block, and a second feed pipe is installed on the left side of the pump head. The second limiting rod is connected to the mounting block, and the positioning block is symmetrically arranged on the left side of the slurry pump body, thereby isolating the device from the material and ensuring the pump head is stably installed on the left side of the slurry pump body.

[0040] In some examples, the mounting block and the second limiting rod are threadedly connected relative to each other, and the second limiting rod is symmetrically arranged about the central axis of the pump head. By rotating the second limiting rod, the second limiting rod is now connected in series with the mounting block, so that the insulating layer connected to the inner side of the mounting block is attached to the interior of the pump head, thereby isolating the material from contacting the pump head.

[0041] In some examples, the positioning block is slidably connected to the pump head and is symmetrically positioned about the central axis of the slurry pump body. By placing the pump head along the positioning block on the left side of the slurry pump body, the pump head is positioned accurately, allowing for more precise installation.

[0042] In some examples, the handle bar and the connecting rod are both rotatably connected to the pump head, and a first connecting plate and a second connecting plate are engaged with each other on the right side of the handle bar. Rotating the handle bar causes the handle bar to rotate the first connecting plate, which in turn drives the second connecting plate and the connecting rod at the upper end of the pump head to rotate, thereby completing the rotation of the connecting rod.
