Description

Technical Field

[0001] The utility model relates to the technical field of stone screens for water conservancy construction, in particular to a stone screen for water conservancy construction with a feeding structure. Background Art

[0002] At present, concrete is used in the construction of water conservancy projects, and gravel is often used as raw material in the preparation of concrete. Due to the different sizes of gravel, it is necessary to screen the gravel according to different water conservancy construction work before use, so a gravel screen will be used.

[0003] According to the description of a multi-layer square hole gravel screen for easy maintenance disclosed on the patent website (authorization announcement number: CN215695775U), "the utility model discloses a multi-layer square hole gravel screen for easy maintenance, including a bottom plate, an upper slide plate and a driving mechanism; the bottom plate: symmetrically distributed springs are arranged at the four corners of its upper surface, and the top ends of the springs are fixedly connected to the lower surface of the lower slide plate, and the upper slide plate is detachably installed on the upper surface of the lower slide plate, and the left end of the upper surface of the upper slide plate and the right end of the upper surface of the lower slide plate are both provided with side plates, and the opposite inner sides of the two side plates are symmetrically provided with sieve plates, and the inside of the sieve plates are provided with square holes distributed in an array, and the two upper sieve plates are installed in cooperation, and the two lower sieve plates are installed in cooperation; the driving mechanism is arranged in the middle of the upper surface of the bottom plate, and the driving mechanism is fixedly connected to the lower surface of the lower slide plate. The multi-layer square hole gravel screen for easy maintenance facilitates the falling of stones clamped in the square holes, improves the efficiency during maintenance, and thus meets different screening needs and increases the scope of application."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model can drive the corresponding turntable to rotate through the dual-axis motor, and the turntable drives the notch plate to swing left and right through the rotating shaft arranged on the side away from the dual-axis motor, and the notch plate drives the screen plate to swing back and forth through the lower slide plate, the upper slide plate and the side plate in turn, and the stone to be screened is placed on the right end of the upper surface of the top screen plate, and the stone is screened through the square holes of the two adjacent screen plates. However, in actual application, the device requires on-site construction workers to transport the stone to the screening equipment through tools such as shovels. Since the screening equipment has a certain height, as the work continues, the labor cost is likely to be greatly increased, and in the process of screening the stone, it is easy to generate more dust. If it is not treated, it is easy to pose a threat to the operating environment and the health of the staff.

[0034] Embodiment 2:

[0035] See also Figure 5 , and combined with Example 1, it is further obtained that the dust collection mechanism 5 includes a second mounting frame 51, the second mounting frame 51 is fixedly mounted on the top of the processing frame 2, a third motor 52 is fixedly mounted on the outside of the second mounting frame 51, a third connecting rod 53 is fixedly mounted on the output shaft of the third motor 52, an impeller 54 is fixedly mounted on the outside of the third connecting rod 53, a filtering and collecting frame 55 is slidably mounted inside the second mounting frame 51, a dust suction pipe 56 is fixedly mounted on the left side of the second mounting frame 51, and a connector 57 is fixedly mounted on the side of the dust suction pipe 56 away from the second mounting frame 51, so as to facilitate the unified treatment of the dust generated during the screening process.

The bottom of the connecting head 57 is fixedly installed on the top of the processing frame 2, and a ventilation hole is opened on the right side of the processing frame 2 to facilitate better absorption of dust and avoid interference with the operating environment.

[0037] In actual operation, when this device is used, when it is necessary to screen the stones for water conservancy construction, the first motor 412 can be turned on according to the height of the different processing frames 2 to rotate the one-way screw 413. Under the action of the limit rod 414, the movable plate 415 can be made to slide inside the first mounting frame 411 to rotate the connecting plate 416. Under the action of the first mounting frame 417, the movable frame 418 can be made to rotate to change the angle of the conveying device 419 and achieve a better feeding effect.

As the conveying device 419 is loaded, the stones will enter the processing frame 2. At this time, the second motor 426 is turned on to rotate the second connecting rod 427. When the cam 428 abuts against the connecting block 425, the movable frame 418 can be made to rotate. The sieve plate 423 is arranged to slide outside the mounting rod 422. When the cam 428 loses contact with the connecting block 425, the sieve plate 423 will be restored to its initial position under the action of the first spring 424. Repeated contact and non-contact can realize the shaking of the sieve plate 423 to screen the stones inside the processing frame 2. Stones smaller than the diameter of the sieve holes of the sieve plate 423 will detach from the sieve plate 423 and fall from the bottom of the processing frame 2. Since the sieve plate 423 is arranged in an inclined manner, stones larger than the diameter of the sieve holes will fall from the stone leakage trough and be guided to the storage location through the guide plate 6. In order to avoid the pollution of the surrounding environment caused by more dust during the screening process, the third motor 52 can be turned on to rotate the third connecting rod 53 so that the set impeller 54 can rotate to generate suction. The generated dust can be collected through the dust suction pipe 56 and the connector 57 and collected inside the filter collection frame 55. After the work is completed, the filter collection frame 55 can be taken out to centrally process the dust.
