By means of the above-described construction, the irrigation duct 3 can be positioned at a desired height by adjusting the angle of the legs 4, depending on the specific position in which the irrigation funnel is to be operated.
The utility model discloses a theory of operation is: the utility model provides a cement emulsified asphalt mortar exhaust fills funnel specially adapted slab ballastless track's preparation, at first will fill pipe 3 that fills that 1 lower part of hopper of funnel set up when filling places in the track board fills downtheholely, through the adjustment the position of landing leg 4 can be controlled fill the height of funnel for fill the lower edge of pipe 3 and keep unanimous basically at the bottom of the track board, and the level, promptly, can conveniently adjust through adjustable landing leg 4 and fill funnel horizontal position and vertical height. In addition, the lowest position of valve plate 70, which is away from the bottom surface of irrigation conduit 3, and the position of scale 76, which is indicated by pointer 75 on drive screw 73, are tested prior to irrigation, as well as the position of valve plate 70 when it is lifted to different heights. When the valve plate 70 is far away from the bottom surface of the pouring guide pipe 3, the pouring guide pipe port is completely opened, the flow rate of the cement emulsified asphalt mortar is fastest, the higher the lifted position of the valve plate 70 is, the smaller the opening degree between the conical surface of the valve plate and the pipe port of the pouring guide pipe 3 is, the slower the flow rate of the cement emulsified asphalt mortar is, and when the valve plate 70 is lifted to seal the pouring guide pipe 3, the position indicated by the pointer 75 is the highest position which can be lifted by the transmission screw 73.
Then, the crank handle 9 is rotated to drive the crank handle 8 and the transmission screw 73 of the mechanical control valve 7 to rotate together, and the valve plate 70 is lifted to a certain height through scale positioning until the filling conduit port is sealed; then the cement emulsified asphalt mortar is injected into the hopper 1 from the outer side of the guide plate through a transfer hopper guide pipe, specifically, the transfer hopper guide pipe is injected into the hopper 1 from an injection part 6 formed between the outer side surface of the guide plate 5, which is back to the open part 50, and the side wall of the hopper 1 through a connecting end 51 of the guide plate. After the mortar is filled in the pouring guide pipe 3 and is submerged below the bottom surface of the hopper 1, the crank 9 is rapidly rotated in the reverse direction, so that the transmission screw 73 drives the valve plate 70 to descend to the lowest position away from the bottom of the pouring guide pipe 3, the pouring guide pipe 3 is completely opened, and the cement emulsified asphalt mortar can fully flow into the track slab cavity along the pouring guide pipe 3 for pouring. In the filling process, the flow can be easily controlled by only maintaining the height of the liquid level in the hopper 1, namely, the liquid level is kept to be over the bottom surface of the hopper 1 (when the liquid level is lower than the bottom surface of the hopper 1, mortar is easy to wrap air bubbles), and air bubbles are not introduced. Meanwhile, under the pressurization effect of the filling conduit 3, the capability of removing gas in the plate cavity by mortar is increased, and the filling speed is controllable through a mechanical connecting rod valve and a scale.
Because the air exhaust filling funnel utilizes the wide flat bottom surface of the hopper 1 and the slow flow and flow guide effects of the guide plate 5 to fully overflow air bubbles wrapped in mortar, the mortar is injected into the plate cavity in a stable and bubble-free mode. The bottom 12 of the hopper 1 may be inclined at an angle of about 5 degrees toward the center, for example, to provide a flow slowing effect.
The mortar is poured into the hopper 1 from the pouring section 6, and during the pouring of the track slab, the mortar enters the open section 50 from the inlet section 52 through the arc section from the outside of the guide plate 5 in the direction indicated by the arrow in fig. 2, and is poured through the pouring pipe 3. Therefore, the flow guide plate 5 prolongs the flow path of the mortar in the hopper 1, increases the slow flow time of the mortar, and can ensure that bubbles wrapped in the mortar are fully overflowed in the flow process of the mortar in the hopper, so that the mortar can be stably injected into the track slab cavity without bubbles. Furthermore, in order to be able to increase the exhaust effect, the height of the baffle 5 must not be too low, and the height of the baffle 5 should generally be flush with or slightly below the height of the hopper 1.
In a specific embodiment, the inner diameter of the hopper 1 is 600 mm plus or minus 10mm, the height is 200 mm plus or minus 5mm, and the wide and flat hopper bottom surface 12 has a certain inclination angle, for example, the angle is about 5-8 degrees, thereby being beneficial to the slow flow and the drainage of the mortar. While the top of the baffle 5 is substantially flush with the top surface of the hopper 1. And the height of the liquid level of the mortar is kept to be 100-150 mm in the pouring process. The perfusion conduit 3 is a steel pipe with the inner diameter phi of 30-100mm or a pipe made of other materials, and the length is 30-80 cm. The valve plate 70 of the mechanical control valve 7 is arranged at the lower pipe orifice of the perfusion conduit 3 and is welded and fixed with the connecting rod 71, and the diameter of the connecting rod 71 is 10mm-20mm and is arranged in the perfusion conduit 3.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
