Description

Technical Field

[0001] This utility model relates to the field of roadbed construction technology, specifically to a saline soil roadbed filling device. Background Technology

[0002] A roadbed is the foundation of a track or road surface, and is an earthwork structure formed through excavation or filling. The main function of a roadbed is to provide the necessary conditions for the laying of tracks or roads and the operation of trains or vehicles, and to bear the static and dynamic loads of tracks, locomotives, rolling stock, roads, and traffic loads, while transferring and dispersing the loads deep into the foundation.

Several stirring rods are symmetrically installed on the lower outside of the rotating shaft, and a spraying component is provided on one side of the storage box. The spraying assembly includes a cylinder fixedly installed on one side of the top of the storage tank, with an extraction pipe penetrating through the bottom of the cylinder and the extraction pipe penetrating through the storage tank, and a delivery pipe penetrating through the lower side of one side of the cylinder.

[0007] Preferably, a one-way valve is provided on the side of the extraction pipe and the delivery pipe near the cylinder, and one end of the delivery pipe passes through the base and is fixedly installed with a telescopic pipe, and the bottom end of the telescopic pipe is connected to a spray pipe, and the bottom of the spray pipe is connected to several nozzles.

[0008] Preferably, a piston is slidably connected inside the cylinder, and an exhaust hole is provided through one side of the top of the cylinder.

[0012] Preferably, the spray pipe is symmetrically slidably connected to a positioning frame, and the positioning frame is fixedly connected to the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this saline soil subgrade filling device allows for simultaneous filling and spraying of salt-inhibiting agents during subgrade filling construction on saline-alkali land, which can reduce the salt content in the soil layer, improve construction efficiency, and ensure uniform spraying while avoiding excessive spraying. The specific details are as follows: 1. During roadbed construction, filler material is added to the filling box, and salt inhibitor is added to the storage box. During construction, a servo motor can be started to drive the rotating shaft to rotate, allowing the mixing rod to mix the filler material and prevent it from accumulating and causing blockage. The electric valve on the filling frame is opened to apply the filler material. The rotation of the rotating shaft can drive the rotating rod to rotate through the meshing of the first and second bevel gears. The rotating rod can drive the turntable to rotate. After the turntable rotates, the movable frame can move up and down through the sliding connection between the column block and the return frame. While the movable frame moves up and down, the movable rod can be driven by the connecting frame to move in the cylinder. When the piston moves upward, the one-way valve inside the delivery pipe closes, and the one-way valve inside the extraction pipe opens, allowing the salt-suppressing agent inside the storage tank to be drawn into the cylinder. Then, when the piston moves downward, the one-way valve inside the delivery pipe opens, and the one-way valve inside the extraction pipe closes, allowing the salt-suppressing agent inside the cylinder to be delivered into the spraying pipe. This allows the nozzles on the spraying pipe to spray the salt-suppressing agent evenly, enabling the simultaneous filling and spraying of salt-suppressing agent during roadbed filling construction on saline-alkali land. This reduces the salt content in the soil, improves construction efficiency, and ensures even spraying while avoiding excessive spraying. 2. During the up-and-down reciprocating movement of the movable frame, the base can slide, and the connecting rod can be pulled to rotate during the movement of the movable frame. After the connecting rod rotates, it can drive the spraying pipe to slide on the positioning frame through the connecting block. This allows the spraying pipe to move back and forth while the movable frame moves up and down, which can expand the spraying range without changing the spraying amount. This improves the uniformity of salt suppressant spraying and avoids the problem of excessive salt suppressant spraying caused by directly increasing the number of nozzles or increasing the spraying range. Excessive salt suppressant (such as that containing calcium chloride) will aggravate soil compaction. Attached Figure Description

[0019] Working principle: Before using this saline soil subgrade filling device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, during roadbed construction, filler material is added to the filling box 101, and salt inhibitor is added to the storage box 104. During construction, the servo motor 106 can be started to drive the rotating shaft 107 to rotate, so that the mixing rod 108 can mix the filler material to prevent it from accumulating and causing blockage. The electric valve on the filling frame 102 is opened to apply the filler material. The rotation of the rotating shaft 107 can drive the rotating rod 208 to rotate through the meshing of the first bevel gear 210 and the second bevel gear 211. The rotating rod 208 can drive the turntable 212 to rotate. After the turntable 212 rotates, the movable frame 213 can be moved up and down through the sliding connection between the column block 216 and the return frame 215. While the movable frame 213 moves up and down, it can be connected by the connecting frame 217. When the movable rod 206 moves on the cylinder 201, and the movable rod 206 drives the piston 207 to move upward, the one-way valve inside the delivery pipe 203 closes and the one-way valve inside the extraction pipe 202 opens, so that the salt inhibitor inside the storage tank 104 can be drawn into the cylinder 201. Then, when the piston 207 moves downward, the one-way valve inside the delivery pipe 203 opens and the one-way valve inside the extraction pipe 202 closes, so that the salt inhibitor inside the cylinder 201 can be delivered into the spraying pipe 205, so that the nozzle on the spraying pipe 205 can spray the salt inhibitor evenly. This allows the filling and spraying of the salt inhibitor to be carried out simultaneously when the roadbed filling construction is carried out on saline-alkali land, which can reduce the salt content in the soil layer, improve construction efficiency, and avoid over-spraying while ensuring uniform spraying. During the reciprocating up and down movement of the movable frame 213, it can drive the base 1 to slide. During the movement of the movable frame 213, it can pull the connecting rod 221 to rotate. After the connecting rod 221 rotates, it can drive the spraying pipe 205 to slide on the positioning frame 219 through the connecting block 220. This allows the movable frame 213 to move up and down while driving the spraying pipe 205 to move back and forth, which can expand the spraying range without changing the spraying amount. This improves the uniformity of salt suppressant spraying and avoids the problem of excessive salt suppressant spraying caused by directly increasing the number of nozzles or increasing the spraying range. Excessive salt suppressant (such as that containing calcium chloride) will aggravate soil compaction.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
