Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5 , This embodiment provides a technical solution: a sand and gravel separation device for landscaping construction, comprising a leg 1, a slope 9 and a separation mechanism 8;
[0026] Legs 1: There are four of them, the tops of the four legs 1 are fixedly connected to the lower surface of a separation shell 3, and also include a single-chip microcomputer 6, which is arranged at the right end of the front side of the separation shell 3, and the input end of the single-chip microcomputer 6 is electrically connected to an external power supply. The front side of the separation shell 3 is provided with evenly distributed heat dissipation ports, and the inner walls of the heat dissipation ports are fixedly connected with a heat dissipation net 2. A feed hopper 4 is fixedly connected to the feed port at the right end of the upper surface of the separation shell 3. First, sand and gravel for landscaping construction are poured from the feed hopper 4 into the interior of the separation shell 3. Due to the effect of free fall, the sand and gravel will fall on the screen 805. A fine material discharge port 5 is provided at the lower end of the right side of the separation shell 3, and a coarse material discharge port 7 is provided in the middle of the left side of the separation shell 3;
[0027] Slope 9: It is fixedly connected to the right side of the bottom wall of the separation shell 3. A guide groove 10 is provided on the upper surface of the slope 9. The guide groove 10 is connected to the fine material discharge port 5. The sand and gravel with a smaller diameter after separation will fall on the slope 9 through the screen 805 and flow to the fine material discharge port 5 through the guide groove 10.
[0028] Separation mechanism 8: It is arranged inside the separation shell 3, and the left end of the separation mechanism 8 is installed in cooperation with the coarse material discharge port 7. The separation mechanism 8 includes a screen 805, an arc-shaped slide rail 806, a mounting frame 807, a pulley 809, a rotating shaft 810 and a fixed cylinder 811. The rotating shaft 810 is rotatably connected between the front and rear inner walls on the right side of the separation shell 3. The outer surface of the rotating shaft 810 is fixedly sleeved with a fixed cylinder 811, and the front end of the outer surface of the fixed cylinder 811 is fixedly connected with the mounting frame 807. The inside of the mounting frame 807 is fixedly connected with the screen 805. The front and rear sides of the left end of the mounting frame 807 are rotatably connected with the pulley 809 through a pin shaft, and the arc-shaped slide rails 806 are both opened on the front and rear inner walls on the left side of the separation shell 3. The inner wall of the arc-shaped slide rail 806 is slidably connected to the outer surface of the adjacent pulley 809, and the center of the arc-shaped slide rail 806 coincides with the center of the rotating shaft 810. The separation mechanism 8 also includes an inclined groove 808, which is opened at the left end of the upper surface of the mounting frame 807. The inclined groove 808 is installed in conjunction with the coarse material discharge port 7. The larger diameter will move to the coarse material discharge port 7 through the inclined groove 808 on the mounting frame 807 under the continuous rotation of the screen 805. The separation mechanism 8 also includes a tension spring 801, which is fixedly connected between the left end of the lower surface of the mounting frame 807 and the left and right ends of the bottom wall of the adjacent separation shell 3. The separation mechanism 8 also includes a mounting seat 802, a motor 803 and a cam 804. The seat 802 is installed on the left end of the bottom wall of the separation shell 3 by bolts, and the upper surface of the mounting seat 802 is installed with a motor 803 by bolts. A cam 804 is fixedly sleeved at the rear end of the output shaft of the motor 803. The outer surface of the cam 804 is matched with the left end of the lower surface of the mounting frame 807 for mounting. The input end of the motor 803 is electrically connected to the output end of the single-chip microcomputer 6. The operation of the motor 803 is regulated by the single-chip microcomputer 6. The rotation of the output shaft of the motor 803 drives the cam 804 to rotate. When the cam 804 rotates, it contacts the lower surface of the mounting frame 807 through its raised parts. When in contact, the movement of these raised parts causes the mounting frame 807 to rotate around the rotating shaft 810 and drives the pulley 80 on the mounting frame 807. As the mounting frame 807 rotates, it moves along the inner wall of the arc-shaped slide rail 806, and at the same time, the tension spring 801 is stretched, so as to ensure stability during rotation. However, as the mounting frame 807 rotates, the screen 805 is also driven to rotate. When the raised portion of the cam 804 is not in contact with the mounting frame 807, the mounting frame 807 will fall freely due to the action of gravity until it contacts the raised portion of the cam 804 again. As a result, the sand and gravel will be lifted up and fall again as the rotation amplitude of the mounting frame 807 and the screen 805 gradually increases. In addition, the movement trajectory and speed change of the sand and gravel during the separation process can be changed by adjusting the rotation speed of the cam 804, so as to effectively solve the problem of uneven vibration.
[0029] The working principle of a sand and gravel separation device for landscaping construction provided by the utility model is as follows: first, sand and gravel for landscaping construction are poured from the feed hopper 4 into the interior of the separation shell 3. Due to the effect of free fall, the sand and gravel will fall on the screen 805. Then, the operation of the motor 803 is regulated by the single-chip microcomputer 6. The output shaft of the motor 803 rotates to drive the cam 804 to rotate. When the cam 804 rotates, its raised parts contact the lower surface of the mounting frame 807. When in contact, the movement of these raised parts causes the mounting frame 807 to rotate around the rotating shaft 810, and drives the pulley 809 on the mounting frame 807 to move along the inner wall of the arc-shaped slide rail 806 as the mounting frame 807 rotates, and at the same time stretches the tension spring 801, so as to ensure stability during rotation. However, as the mounting frame The rotation of 807 also drives the screen 805 to rotate. When the raised part of the cam 804 is not in contact with the mounting frame 807, the mounting frame 807 will fall freely due to the effect of gravity until it contacts the raised part of the cam 804 again. As a result, the sand and gravel will be lifted up and fall down again as the rotation amplitude of the mounting frame 807 and the screen 805 gradually increases. By adjusting the rotation speed of the cam 804, the movement trajectory and speed change of the sand and gravel in the separation process can be changed, thereby effectively solving the problem of uneven vibration. The sand and gravel with smaller diameters that have been separated will pass through the screen 805 and fall on the slope 9, and flow to the fine material discharge port 5 through the guide groove 10. The sand and gravel with larger diameters will move to the coarse material discharge port 7 through the inclined groove 808 on the mounting frame 807 under the continuous rotation of the screen 805.

The single chip microcomputer 6 controls the motor 803 to work using a method commonly used in the prior art.
