Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering equipment technology, and in particular to a water conservancy engineering grouting construction equipment that avoids nozzle blockage. Background Technology

[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing hydraulic engineering projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the water needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways to achieve their objectives. Grouting equipment is typically used during the construction of hydraulic engineering projects.

[0003] Existing grouting equipment for water conservancy projects is prone to clogging of the nozzle during use, making it inconvenient to remove materials. At the same time, some materials tend to remain inside the equipment, making cleaning difficult. It is also inconvenient to compact the discharged concrete, which can easily lead to hollow concrete. Therefore, we propose a grouting equipment for water conservancy projects that avoids nozzle clogging. Summary of the Invention

[0037] Working principle: During operation, concrete is discharged through the conduit 2 and the discharge cylinder 1. The motor 6 is then switched on. The output shaft of the motor 6 drives the drive rod 7 to rotate. The rotating drive rod 7, through the meshing of the third bevel gear 12 and the fourth bevel gear 13, drives the transmission rod 9 to rotate. The transmission rod 9, through the meshing of the first bevel gear 10 and the second bevel gear 11, drives the rotating shaft 4 to rotate. The rotating shaft 4, through its sliding connection with the second bevel gear 11, rotates, thereby driving the top rod 30 and the scraper 31 to rotate via the fixed column 29. The scraper 31... The inner wall of the discharge cylinder 1 is cleaned, and the top spring 33 pushes the top rod 30, so that the scraper 31 keeps in contact with the inner wall of the discharge cylinder 1. The rotating drive rod 7 drives the rotating ring 19 to rotate through the meshing of the drive gear 16 and the external gear ring 15. The rotating ring 19 is slidably connected to the positioning shaft 24 through multiple inclined grooves 23, so as to drive the moving rod 20 to move back and forth. The moving rod 20 taps the discharge cylinder 1 through the striking block 22, so as to facilitate the unblocking and cleaning of the discharge cylinder 1. The moving rod 20 is connected to the rotating shaft 4 through the wedge block 25. The rotating rings 19 and 19 rotate together, and under the action of the baffle 26 and the return spring 27, the rotating shaft 4 vibrates up and down, which facilitates the rotation of the auger 5 to guide the material and also facilitates the unblocking of the guide tube 2 and the discharge cylinder 1. The rotating ring 19 drives the collar 40 to rotate. The collar 40 is slidably connected to the two movable shafts 43 through the corrugated groove 41, which can drive the sleeve 34 to move up and down. The sleeve 34 is threadedly connected to the connecting rod 38, which can drive the vibrating ring 39 to vibrate up and down, which facilitates the compaction of the discharged concrete. When it is necessary to adjust the vibration depth, the rotating ring 19 rotates up and down. The rotating plate 55, through the meshing of two driven gears 49 with the internal gear ring 48, can drive the two connecting rods 38 to rotate simultaneously. The rotating connecting rods 38 are threadedly connected to the sleeve 34, thereby adjusting the distance between the vibrating ring 39 and the base plate 28, and thus adjusting the vibration depth. The connecting block 51 is slidably connected to the annular slide groove 50, and the slider 53 is slidably connected to the positioning groove 52, thereby positioning the internal gear ring 48 and the vibrating ring 39, so that the internal gear ring 48 can rotate stably on the vibrating ring 39.

[0038] Example 2

[0039] The difference between Embodiment 2 and Embodiment 1 is that a swing rod 54 is fixedly installed at the bottom of the moving rod 20. The swing rod 54 is designed to evenly discharge the concrete, thus facilitating the uniform placement of the concrete during discharge.
