[0022] The utility model is described in further detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides an anti-clogging sand screening machine for water conservancy projects, comprising a shell 1, a top cover 2 fixedly mounted on the top of the shell 1 and a vibration motor 7, a spring seat 3 fixedly mounted on the upper inner side of the shell 1, a screen frame 4 fixedly mounted on the inner side of the spring seat 3, a feeding assembly 5 and a driving assembly 6 located above the screen frame 4 fixedly mounted on the top of the top cover 2, a dust collection assembly 10 fixedly mounted on the inner side of the shell 1, the screen frame 4 comprises a frame 41, a screen 42 is fixedly mounted on the bottom of the frame 41, a cylinder 43 is provided on the side of the frame 41, the feeding assembly 5 comprises a feeding pipe 51, the feeding pipe 51 is rotatably connected to the middle part of the inner side of the top cover 2, a fixing frame 52 located on the inner side of the frame 41 is fixedly mounted on the outer side of the feed pipe 51, and a cleaning brush 53 located on the outer side of the inner side of the frame 41 is fixedly mounted below the fixing frame 52.

[0024] The driving assembly 6 can drive the feeding pipe 51 to rotate so that the sand is evenly spread on the screen 42 through the bottom of the feeding pipe 51. When the sand falls on the screen 42 and the vibration motor 7 drives the frame 41 and the screen 42 to vibrate and screen the sand, the cleaning brush 53 is set to rotate with the feeding pipe 51 to sweep the impurities remaining in the frame 41 and discharge them from the waste outlet 44, thereby facilitating the cleaning of the screen 42 to avoid blockage, and at the same time, the sand can be evenly distributed and screened, thereby improving the sand screening efficiency.

[0025] like Figure 3 As shown, the drive assembly 6 includes a mounting bracket 61, which is fixedly mounted on the top of the top cover 2. A drive motor 62 is fixedly mounted on the top of the mounting bracket 61. A transmission wheel 63 is fixedly mounted on the outside of the feed tube 51 and the outside of the output shaft of the drive motor 62. A transmission belt 64 is movably mounted on the outside of the transmission wheel 63.

[0026] The driving motor 62 drives the transmission wheel 63 outside its output shaft to rotate, and the transmission wheel 63 set on the outside of the feed pipe 51 cooperates with the transmission belt 64 to drive the feed pipe 51 to rotate slowly, wherein the transmission wheel 63 and the transmission belt 64 respectively adopt a pulley and a toothed belt, and the transmission wheel 63 located outside the feed pipe 51 is larger in size, thereby ensuring that the feed pipe 51 is stably driven to perform a deceleration motion and slow rotation, so as to ensure that the sand is evenly distributed through the feed pipe 51.

[0027] like Figure 4 As shown, a cylinder 43 connected to the screen 42 is provided in the middle of the inner side of the frame 41 , and the vibration motor 7 is fixedly installed inside the cylinder 43 .

[0028] By setting up the cylinder 43 and installing the vibration motor 7 therein, the vibration motor 7 is connected to the outside to generate vibration, thereby driving the frame 41 and the screen 42 located on the spring seat 3 to vibrate. By adjusting the amplitude of the vibration motor 7, the problem of clogging of the screen 42 is reduced and the sand screening efficiency is guaranteed.

[0029] like Figure 4 As shown, the top surface of the screen 42 is inclined outward.

[0030] The top surface of the screen 42 is tilted downward outward, so that the sand falls on the screen 42 and rolls outward with the vibration. In the process, the sand is screened out through the screen 42, while larger impurities remain above the screen 42.

[0031] like Figure 3 As shown, the cleaning brush 53 is arranged at an angle to fit the screen 42 , and the cleaning brush 53 abuts against the inner side of the frame 41 .

[0032] The cleaning brush 53 is tilted and fits the screen 42 and its base is on the inner side of the frame 41 , so that when the cleaning brush 53 rotates, the retained impurities are swept to the waste outlet 44 for discharge, making it easier to clean the screen 42 .

[0033] like Figure 3 As shown, a debris discharge channel 8 located below the waste discharge port 44 and communicating with the outside is fixedly installed inside the housing 1 , and a discharge port 9 is provided on a side of the housing 1 away from the debris discharge channel 8 .

[0034] The impurities discharged from the waste outlet 44 can be received by the impurity discharge channel 8, and the lower part of the impurity discharge channel 8 is connected to the outside, so the impurities can be directly discharged into the shell 1, and the screened sand can be collected by the discharge port 9.

[0035] like Figure 5As shown, the dust collection assembly 10 includes a dust collection hood 101, a dust collector 102 and a connecting pipe 103. The dust collection hood 101 is fixedly installed on the inner side of the shell 1, the dust collector 102 is fixedly installed on the outer side of the shell 1, and the connecting pipe 103 is fixedly connected between the dust collection hood 101 and the dust collector 102.

[0036] The dust collecting hood 101 is arranged above the inner side of the discharge port 9 .

[0037] The dust hood 101 is arranged above the discharge port 9, and the dust is sucked in from the dust hood 101 by the vacuum cleaner 102 through the connecting pipe 103, and the outer shell 1 and the top cover 2 are used for overall shielding, thereby reducing the dust in the sand screening process and reducing the impact on the health of the construction workers.

[0038] The following is a detailed description of the working principle of the anti-clogging water conservancy project sand screening machine.

[0039] like Figures 1 to 5 As shown, by controlling to open the vibration motor 7 and the driving motor 62 connected to the outside, the driving motor 62 drives the transmission wheel 63 outside its output shaft to rotate, and the transmission wheel 63 arranged outside the feeding pipe 51 cooperates with the transmission belt 64 to drive the feeding pipe 51 to rotate slowly. Since the discharge port 9 below the feeding pipe 51 is eccentrically arranged, the sand to be screened is added from the feeding pipe 51, and the sand is evenly distributed on the inside of the frame 41 through the rotation of the feeding pipe 51. The frame 41 is installed on the spring seat 3 and the vibration motor 7 located in the cylinder 43 drives the frame 41 and the screen 42 to vibrate to screen the sand. The sand is distributed on the inner side of the top of the screen 42. Since the top of the screen 42 is tilted outward, the sand rolls outward with the vibration. In the process, the sand screened out passes through the screen 42 and falls to the outside. The impurities screened out stay on the screen 42 and are blocked by the frame 41. When the feed pipe 51 rotates, the fixing frame 52 is driven to rotate. The bottom of the fixing frame 52 is located at the connecting corner of the frame 41 and the screen 42. The cleaning brush 53 rotates with the fixing frame 52 to sweep the remaining impurities toward the waste outlet 44. The impurities reach the waste outlet 44 and fall into the impurity discharge channel 8 and roll out of the outer shell 1. The screened sand is discharged and collected from the discharge port 9. During the sand screening process, the vacuum cleaner 102 is turned on and the dust hood 101 is used to connect the dust hood 101 through the vacuum cleaner 102. The dust overflowing from the discharge port 9 during the sand screening process is sucked away by the dust hood 101. The overall sealing of the outer shell 1 and the top cover 2 is good, which reduces dust and reduces the impact on construction personnel.

[0040] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
