Description

A slurry feeder

technical field

The invention relates to a slurry pouring device, in particular to a slurry feeder.

Background technique

In the groutability test of concrete crack grout, in order to realize the comparison of the groutability of different grouts, it is necessary to pour the grout into the simulated cracks, and then compare the fullness of different performance grouts in the simulated cracks , filling time and other groutability indicators, so that the groutability of the grouting material can be evaluated. However, if the feeding equipment and operation methods used are not uniform, such as using funnels of different sizes or shovels of different sizes for perfusion feeding, or the distance between the mouth of the funnel or the shovel and the simulated crack opening is different due to human factors All directly affect the accuracy of the test results. At the same time, due to the differences in the consistency and viscosity of the various grouting materials in the comparative test, feeding utensils of different specifications need to be used, which increases the cost and brings inconvenience to the operation. In addition, it is not easy to grasp how much grouting material needs to be added in the grout feeder. Adding too much will cause waste, adding too little will not fill the simulated cracks, and refilling will cause test errors or even lead to test failure. Therefore, in order to ensure the accuracy of test results and improve test efficiency, it is necessary to develop a standard slurry injection device.

Contents of the invention

The purpose of the present invention is to provide a slurry pouring device, in particular to a slurry feeder.

In order to achieve the above object, the technical solution adopted in the present invention is:

A slurry feeder, comprising a barrel body with a material inlet and a material outlet, a gate for adjusting the opening of the material outlet, a gate rotating shaft, a turntable and a turntable tightening screw, the gate is located at the The discharge port is set on the barrel body through the pitch rotation of the ram rotating shaft, the turntable is fixedly arranged with the ram through the ram rotating shaft, and the turntable has arc-shaped slot holes, so The turntable tightening screw passes through the arc-shaped slot and is arranged on the barrel body.

Preferably, at least one side in the up-down direction of the arc-shaped slot hole is provided with an outlet adjustment scale.

Preferably, a capacity scale for determining the amount of grouting material poured is provided on the inner wall of the barrel.

Preferably, bushings are provided on the front and rear outer walls of the outlet, and the rotating shaft of the shutter is rotatably inserted in the corresponding bushings.

Preferably, a bracket is also included, and the upper end of the barrel body has an everted edge that overlaps with the bracket or a sliding sleeve that slides and fits with the bracket. A kind of slurry feeder of the present invention, according to the grouting materials of different properties, adjusts the opening of the discharge port by rotating the turntable to drive the shutter, and then fixes the turntable by tightening the screws of the turntable. The angle of the plate is fixed, so as to fix the opening of the discharge port, adjust the flow rate of the grouting material, ensure the flow rate is controllable, and prevent the test from failing due to too fast or too slow feeding. At the same time, the structure of the grout discharger is simple, low cost.

Furthermore, at least one side of the arc-shaped slot hole in the up-down direction is provided with a discharge opening adjustment scale, which can precisely adjust the angle of rotation of the gate, thereby accurately controlling the opening of the discharge opening.

Furthermore, the inner wall of the barrel is provided with a capacity scale for determining the amount of grouting material poured in, which can accurately control the amount of grouting material added in the grout feeder according to the capacity of the simulated crack in the test, and prevent the amount of grouting added. Insufficient, while avoiding the waste of grouting material.

Furthermore, the setting of the support enables the slurry feeder to slide on the support. After adjusting the opening of the discharge port, the discharge seam formed by the inner wall of the discharge port and the ram can be easily aligned with the middle of the simulated crack , to facilitate the grouting material to enter the simulated cracks.

detailed description

A slurry feeder, as shown in Figure 1-2, includes a barrel body 2 with a material inlet 1 and a material outlet 5, a ram 11 for adjusting the opening of the material outlet 5, and a ram shaft 10 , shaft sleeve 9, turntable 8, turntable tightening screw 7 and support 6, the barrel body 2 is an inverted truncated square cone structure, and the discharge port 5 of the barrel body 2 is a rectangular structure whose length extends along the front and rear directions. The length of the port 5 matches the length of the simulated crack 13 . The flashboard 11 is located at the discharge port 5 and is arranged on the barrel body 2 through the pitch rotation of the flashboard rotating shaft 10. Specifically, the bushing 9 is arranged on the front and rear side outer walls of the discharge port 5, and the flashboard rotating shaft 10 is rotated and inserted in the In the corresponding bushing 9, the turntable 8 is fixedly arranged through the ram shaft 10 and the ram 11, and the turntable 8 has an arc-shaped slot hole, and at least one side of the arc-shaped slot hole is provided with a discharge opening adjustment scale. In the example, both sides are provided with discharge opening adjustment scales, and the turntable tightening screw 7 passes through the arc-shaped slot and is arranged on the barrel body 2, and the gate plate 11, the gate rotating shaft 10, the shaft sleeve 9, the turntable 8, and the turntable are rotated. The tightening screws 7 and the like form a valve structure that can accurately control the release rate of the grouting material. The inner wall of the barrel body 2 is provided with a capacity scale 3 for determining the amount of grouting material poured in. During the test, the grouting material poured into the grout feeder is about 1.05-1.05% of the volume of the simulated crack when the simulated crack reaches the maximum set width. 1.2 times, the upper end of the barrel body 2 has an eversion edge that overlaps with the support 6 or a sliding sleeve that is slidingly fitted with the support. In this embodiment, it is a sliding sleeve.
