Description

Technical Field

[0001] This utility model relates to the field of sand making machine technology, and in particular to a sand making device with an arc-shaped sand conveying pipe. Background Technology

[0002] Chinese patent announcement number CN217664519U, with an announcement date of October 28, 2022, discloses a sandblasting machine, comprising: a housing, a shot blaster disposed at the top of the housing; a sliding assembly disposed inside the housing, the sliding assembly including a drive unit and a screening unit connected to the actuating end of the drive unit, the screening unit being inclined to the bottom surface of the housing, the screening unit including a frame slidably connected to the inside of the housing and a screen disposed inside the frame; the housing having a discharge port, one end of the screen extending beyond the discharge port, the spherical objects thrown by the shot blaster falling onto the screen and being discharged from the discharge port to the outside of the housing. This sandblasting machine thoroughly cleans impurities and has a simple structure that is easy to implement. The existing technology has the following drawbacks in daily use: The sand conveying pipes generally use composite rubber hoses. While these hoses are tough, wear-resistant, flexible, and non-rigid, making them suitable for transporting sand, after the sandblasting machine has been operating for a period of time, the steel shot impacts and heats up, causing the hose to soften and stretch. The impact point cannot withstand this for even a day, and the composite rubber hose wears through and needs replacement. This results in frequent replacements of the sand conveying hoses throughout the sandblasting process, significantly impacting production efficiency. Therefore, improvements are urgently needed. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a sand-making device with an arc-shaped sand-feeding pipe, which, while ensuring the smooth flow of steel sand in the pipe, extends the service life of the arc-shaped sand-feeding pipe, thereby directly improving production efficiency.

[0004] This utility model provides a sand-blasting device with an arc-shaped sand-feeding pipe, including a sand-blasting machine body. The sand-blasting machine body is equipped with a sand-feeding mechanism, a sand-storage mechanism, and multiple shot blasting heads. The sand-storage mechanism is connected to the shot blasting heads via the arc-shaped sand-feeding pipe. The arc-shaped sand-feeding pipe includes a composite rubber hose section and an arc-shaped metal pipe section. One end of the composite rubber hose section is connected to the sand outlet of the sand-storage mechanism, and the other end of the composite rubber hose section is connected to one end of the arc-shaped metal pipe section. The other end of the arc-shaped metal pipe section is connected to the shot blasting heads. A thickened layer is provided at the arc-shaped bend transition of the arc-shaped metal pipe section.

[0005] Preferably, a flange is installed at the connection end between the composite hose section and the sand outlet.

[0006] Preferably, a flange is installed at the connection end between the composite hose section and the arc-shaped metal pipe section.

[0007] Preferably, a flange is installed at the connection end between the arc-shaped metal pipe section and the shot blasting head.

[0008] Preferably, the arc-shaped metal pipe segment is a CHS 60*6 iron pipe.

[0009] The beneficial effects of this utility model are as follows: The sand conveying arc pipe includes a composite rubber hose section and an arc-shaped metal pipe section. The arc-shaped metal pipe section does not deform when heated, thus maintaining the fixation of the pipeline. The greater the curvature of the arc-shaped metal pipe section, the smoother the steel sand flows in the pipe, the less impact on the pipe wall, and the longer the service life of the sand conveying arc pipe, reducing the replacement frequency and thus improving production efficiency. The arc-shaped bend transition of the arc-shaped metal pipe section is the main impact point. A thickened layer is provided at the arc-shaped bend transition of the arc-shaped metal pipe section. After wear and breakage, the thickened layer can be replaced, further improving the overall service life of this structure. Attached Figure Description
