The concrete slurry screening device is provided with a movable rod, a first spring and a vertical plate, so that when the screening frame moves to the left, the movable rod can be moved to the left, so that the first spring can be contracted, so that it is more convenient to reset the screening frame through the first spring, and further, the screening frame can be swung left and right instead of up and down, thereby solving the problem that some of the screening paddle devices are swung up and down, which makes it easy for concrete to splash out of the screening frame during screening, thereby causing certain difficulties for the user.

[0003] Based on what is stated in the above-mentioned document: Concrete slurry is needed in highway engineering construction, and during the manufacturing process of concrete mortar, a slurry screening device is needed to screen out material particles that do not meet the requirements in the concrete mortar. However, when the above-mentioned slurry screening device is in use, it is impossible to perform double-layer screening treatment on the material particles in the concrete mortar. As the slurry screening proceeds, the screened material remains inside the screening frame, which makes it inconvenient to centrally collect and process the screened material particles. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a concrete mortar screening device for highway engineering construction, which solves the problem that the existing concrete mortar screening device cannot perform double-layer screening treatment on the material particles in the concrete mortar. As the screening proceeds, the screened material remains inside the screening frame, making it inconvenient to centrally collect and process the screened material particles.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: based on the concrete mortar screening equipment for highway engineering construction, including an equipment frame, the top of the equipment frame is provided with a material dropping mechanism, the left side of the equipment frame is provided with a screening mechanism, and the screening mechanism includes:

[0010] Preferably, a folding plate is fixedly connected to the surface of the equipment rack, a limiting groove is provided on the surface of the folding plate, and an inner surface of the limiting groove is slidably connected to the surface of the fixing rod.

[0011] Preferably, the material dropping mechanism includes a material storage box installed on the top of the equipment frame, the bottom of the material storage box is fixedly connected to a material dropping tube, the rear side of the material dropping tube is fixedly connected to an opening and closing motor, one end of the output shaft of the opening and closing motor is fixedly connected to a screw rod through a coupling, and the surface of the screw rod enables the opening and closing plate to rotate through a linkage assembly.

[0013] Beneficial Effects

[0014] The utility model provides a concrete mortar screening device for highway engineering construction. Compared with the prior art, it has the following beneficial effects:

[0015] (1) The concrete mortar screening equipment for highway engineering construction starts a driving motor to drive the driving gear to rotate. The rotation of the driving gear causes the rotating gear, the rotating rod and the connecting rod to rotate synchronously. One end of the connecting rod rotates at one end of the transmission rod, causing one end of the transmission rod to rotate at one end of the fixed rod, thereby causing the fixed rod to slide back and forth on the inner surface of the limiting groove, thereby causing the screening frame to slide back and forth. By providing a screening mechanism, the screening frame can slide back and forth, thereby accelerating the screening efficiency of the coarse screen plate and the screening holes and avoiding accumulation and blockage.

[0016] (2) The concrete mortar screening equipment for highway engineering construction drives the screw to rotate by starting the opening and closing motor. The rotation of the screw causes the linkage block and the moving block to slide synchronously. The linkage block slides on the surface of the limit rod, causing the moving block to slide on the inner surface of the moving groove, thereby causing the linkage plate, the linkage rod and the opening and closing plate to rotate counterclockwise to open the drop pipe. By providing a drop mechanism, the size of the drop pipe opening can be freely adjusted, thereby controlling the drop rate of the concrete mortar and avoiding a large drop amount that affects the screening quality.

[0028] Embodiment 2

[0029] The main difference from the first embodiment is:

[0030] Based on the concrete mortar screening equipment for highway engineering construction, the blanking mechanism 2 includes a storage box 21 installed on the top of the equipment frame 1, and a blanking pipe 22 is fixedly connected to the bottom of the storage box 21, and an opening and closing motor 23 is fixedly connected to the rear side of the blanking pipe 22. The opening and closing motor 23 is a three-phase asynchronous motor and is connected to the external circuit through wires.

The inner surface of the movable groove 254 is slidably connected with the surface of the movable block 253. One end of the linkage plate 252 is fixedly connected to the inside of the opening and closing plate 26 through the linkage rod. By starting the opening and closing motor 23 to drive the screw rod 24 to rotate, the rotation of the screw rod 24 causes the linkage block 251 and the movable block 253 to slide synchronously. The linkage block 251 slides on the surface of the limit rod, so that the movable block 253 slides on the inner surface of the movable groove 254, and then the linkage plate 252, the linkage rod and the opening and closing plate 26 rotate counterclockwise, so as to open the blanking tube 22. By providing the blanking mechanism 2, the opening size of the blanking tube 22 can be freely adjusted, thereby controlling the blanking rate of the concrete mortar, avoiding a large amount of blanking and affecting the screening quality. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, first, the screw rod 24 is driven to rotate by starting the opening and closing motor 23. The rotation of the screw rod 24 causes the linkage block 251 and the moving block 253 to slide synchronously. The linkage block 251 slides on the surface of the limit rod, causing the moving block 253 to slide on the inner surface of the moving groove 254, thereby causing the linkage plate 252, the linkage rod and the opening and closing plate 26 to rotate counterclockwise, thereby opening the drop pipe 22, realizing the drop operation of the concrete mortar, and causing the mortar to fall onto the surface of the coarse screen plate 316 installed on the inner wall of the screening frame 315. Subsequently, the driving motor 321 is started to drive the driving gear 322 to rotate. The rotation of the driving gear 322 causes the rotating gear 313, the rotating rod 312 and the connecting rod 314 to rotate synchronously. Rotate, one end of the connecting rod 314 rotates at one end of the transmission rod 41, so that one end of the transmission rod 41 rotates at one end of the fixing rod 42, and then the fixing rod 42 slides back and forth on the inner surface of the limiting groove 6, so that the screening frame 315 slides back and forth, thereby accelerating the screening efficiency of the coarse screen plate 316 and the screening hole 317. After the concrete mortar falls on the surface of the coarse screen plate 316, the coarse screen plate 316 performs preliminary screening on the concrete mortar, so that the larger sand and gravel are discharged through the discharge pipe on the front side of the screening frame 315, and the smaller sand and gravel are discharged through the discharge port on the right side of the screening frame 315. The liquid mortar passes through the screening hole 317 and drips to the collection frame placed at the bottom of the equipment frame 1 for collection.
