[0029] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] Example:

[0031] The specific implementation of the utility model is as follows Figure 1-4 As shown, a mud perfusion stone screening device for engineering includes a horizontally arranged base 2. A mud breaking mechanism 1 is arranged above the base 2, and a separation mechanism located below the mud breaking mechanism 1 is also installed on the upper surface of the base 2. Among them, the separation mechanism includes a guide seat 3 fixed on the base 2, and the upper surface of the guide seat 3 is inclined to one side. A guide bucket 4 is fixed on the inclined side of the guide seat 3, and a discharge pipe 5 is connected to the side of the guide bucket 4 away from the guide seat 3. At the same time, support plates 7 are provided on both side edges of the upper surface of the guide seat 3, and support columns 8 are provided at both ends of the support plate 7. A vertically arranged sliding rod is fixed on the top of the support column 8, and a support block 9 that can move back and forth up and down is slidably connected to the sliding rod. A horizontally arranged screening trough 10 is fixed between the multiple support blocks 9, and the bottom surface of the screening trough 10 is a detachably connected screen 11. The screening trough 10 is also provided with a cleaning mechanism for cleaning the sand and gravel on the screen 11.

[0032] In this embodiment, the mud breaking mechanism 1 is an authorized technology disclosed in the Chinese utility model patent with announcement number CN222065473U. Its internal structure and working principle are well known to those skilled in the art and are not the innovation of this embodiment. The innovation focus of this embodiment is to automatically clean the sand and gravel, and to divert and collect the separated mud and improve the screening effect. Therefore, this embodiment will not describe its internal structure and working principle in detail.

[0033] When the engineering mud perfusion stone screening device is used, the device is first placed at the desired location, and the mud is added to the mud breaking mechanism 1. After the mud is broken up, it is discharged through the mud breaking mechanism 1 and falls into the screening tank 10. At this time, the up and down movement of the screening tank 10 facilitates better separation of the mud. Then, the separated mud will fall onto the upper surface of the guide seat 3, and flow into the guide bucket 4 under the guidance of the inclined surface of the upper surface of the guide seat 3. At this time, people can directly collect the mud through the discharge pipe 5, or connect the discharge pipe 5 to a longer external pipe to discharge the mud. Of course, if the transportation distance is very long, people can also connect the discharge pipe 5 to a mud pump to facilitate the rapid discharge of the separated mud.

[0034] The mud perfusion stone screening device for the project facilitates the screening and separation of the mud by shaking the screening trough 10 and the screen 11 up and down, thereby improving the screening effect. At the same time, the cleaning mechanism can automatically take out the screened sand and gravel, so it is easy to use. In addition, through the guide seat 3 and the guide bucket 4, in conjunction with the discharge pipe 5 that can be connected to the pipeline or mud pump, the screened mud can be diverted to avoid the mud from flowing randomly, effectively protecting the construction site and environment. In addition, the device can also easily collect the mud in a centralized manner, thereby facilitating the subsequent centralized treatment of the mud.

[0035] In this device, in order to realize the up and down movement of the screening tank 10 and the screen 11, an arc block 14 is fixedly provided on the lower surface of the screening tank 10 near the support plate 7. A rotating shaft is rotatably connected inside the support plate 7, and two elliptical blocks 15 are fixedly sleeved on the rotating shaft, and the elliptical blocks 15 are adapted to the arc block 14. A motor 16 is also installed on the support plate 7, and the output end of the motor 16 passes through the support plate 7 and is fixedly connected to the rotating shaft. When in use, the motor 16 is started first, and the motor 16 will drive the rotating shaft and the elliptical block 15 to rotate, and the elliptical block 15 will push the arc block 14, so that the screening tank 10 and the screen 11 shake up and down, so as to better separate the mud.

[0036] In this embodiment, a spring 12 is sleeved on the slide bar above the support block 9, and a limit block 13 is fixedly connected to the top of the slide bar to prevent the spring 12 from detaching. By compressing and resetting the spring 12, the purpose of strengthening the shaking can be achieved, thereby improving the separation effect of the mud.

[0037] As for the specific structure of the cleaning mechanism, the cleaning mechanism includes an electric cylinder 17 and a shielding plate 18. Among them, the output end of the electric cylinder 17 horizontally and vertically penetrates one side wall of the screening tank 10, and the output end of the electric cylinder 17 is fixedly connected to a push plate 19. The shielding plate 18 is rotatably connected to the other side wall of the screening tank 10 opposite to the electric cylinder 17. When there are a lot of sand and gravel in the screening tank 10, people can open the shielding plate 18 and then put a container under the shielding plate 18. At this time, start the electric cylinder 17, the electric cylinder 17 will drive the push plate 19 to move, and the push plate 19 will push the sand and gravel in the screening tank 10 out, which is convenient for people to take out and collect the sand and gravel, and improves practicality.

[0038] In this embodiment, in order to prevent the shielding plate 18 from being opened at will, two connecting plates are fixedly connected to the shielding plate 18, and the connecting plates are detachably connected to the screening tank 10 through hand-tightened screws. At the same time, in order to improve the stability of the installation of the electric cylinder 17, a fixing plate 20 is fixedly connected to the outer wall of the screening tank 10, and the electric cylinder 17 is installed on the fixing plate 20. In addition, in order to improve the stability of the push plate 19 when moving, the side walls of the screening tank 10 on both sides of the electric cylinder 17 are penetrated with telescopic rods 21 extending in the same direction as the output direction of the electric cylinder 17, and one end of the telescopic rod 21 is fixedly connected to the push plate 19. In addition, in order to facilitate the opening / closing of the shielding plate 18, a handle 24 is fixedly connected to the shielding plate 18.

[0039] It should be further explained that the motor 16 and the electric cylinder 17 in this embodiment are conventional devices purchased on the market and known to those skilled in the art. The models can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structure and function. For technicians in this field, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and they will not be described in detail here. The motor 16 and the electric cylinder 17 are provided with matching control switches. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control.
