Description

Technical Field

[0001] The utility model belongs to the technical field of rock and soil screening, and in particular relates to a rock and soil screening device. Background Art

[0002] Geotechnical engineering is a general term for any kind of rock and soil that make up the earth's crust from the perspective of engineering construction. Geotechnical engineering is needed in civil engineering and water conservancy construction. When rock and sand are mixed, in order to separate them conveniently, the sand is sieved out by screening.

[0003] A Chinese patent with authorization announcement number CN 218108418 U discloses a rock and soil screening device, including a box body, the inner wall of the box body is fixedly connected to a mounting bar, the upper surface of the mounting bar is fixedly connected to a spring shock absorber, the top of the spring shock absorber is fixedly connected to an inclined vibration plate, the lower surface of the inclined vibration plate is fixedly connected to a vibration motor, and the upper surface of the inclined vibration plate is provided with a mounting opening, the inner wall of the mounting opening is fixedly connected to a filter screen, the side of the box body is fixedly connected to a collection box, the inner bottom wall of the collection box is fixedly connected to a sleeve, and the inner bottom wall of the sleeve is fixedly connected to a spring. In the rock and soil screening device, a vibration motor drives the inclined vibration plate to vibrate, and the filter separates the rock and sand. The rock moves to the top of the collection box through the inclined vibration plate and falls on the bottom plate. The impact force of the rock on the bottom plate acts on the sliding rod, and the sliding rod presses down the spring. The spring absorbs energy to protect the bottom plate, thereby preventing the rock from falling and colliding with the collection box and causing damage to the collection box. However, the screening device does not have a component for cleaning the filter. After a long period of rock and soil screening, the mesh of the filter is easily blocked by rock and soil, which affects the efficiency of rock and soil screening. Utility Model Content

[0009] The beneficial effect of this improvement is that when rock and soil fall onto the screen plate, the rock remains on the screen plate and slides to the lowest point of the screen plate. When the bottom end of the screen plate rotates to the first discharge port, the rock is discharged along the first discharge port.

[0010] In order to ensure the stability of the rotation of the swivel and screen plate:

[0011] As a further improvement of the above technical solution: limit rings are symmetrically arranged on the top and bottom of the rotating ring, and limit grooves matched with the limit rings are symmetrically opened on the inner top wall and inner bottom wall of the rotating groove.

[0012] The beneficial effect of this improvement is that when the motor drives the gear to rotate, it drives the rotating ring and the sieve plate to rotate along the rotating groove, and at the same time drives the limiting ring to rotate along the limiting groove, which can ensure the stability of the rotation of the rotating ring and the sieve plate.

[0013] To enable complete cleaning of the screen:

[0014] As a further improvement of the above technical solution: the length of the through-hole brush is the same as the radius of the sieve plate.

[0015] The beneficial effect of this improvement is that when the sieve plate needs to be unblocked, the through-hole brush is driven to move up and down with the cooperation of the electric telescopic rod, and the through-hole brush can unblock the mesh holes on the sieve plate. As the sieve plate rotates, the entire sieve plate can be fully cleaned.

[0016] To enable the screening of rocks and sand:

[0017] As a further improvement of the above technical solution: a second discharge port is arranged at the bottom of the screening drum, and a first aggregate box and a second aggregate box are arranged below the first discharge port and the second discharge port, respectively.

[0018] The beneficial effect of this improvement is that the rocks remaining on the screen plate fall into the first aggregate box along the first discharge port, and the sand passing through the screen plate falls into the second aggregate box along the second discharge port, thereby achieving screening of rocks and sand.

[0019] To achieve rock and dust separation:

[0020] As a further improvement of the above technical solution: a dust filter plate is arranged inside the first material collection box, and support blocks for supporting the dust filter plate are arranged at the four corners inside the first material collection box.

[0021] The beneficial effect of this improvement is that when the screened rocks fall onto the dust filter plate on the first aggregate box, the dust on the rocks passes through the dust filter plate and falls into the first aggregate box, thereby achieving separation of the rocks and the dust.

[0022] In order to prevent the rock and soil from being discharged from the first outlet without being screened by the screen plate:

[0023] As a further improvement of the above technical solution: the feed hopper is arranged on the opposite side of the first discharge port.

[0024] The beneficial effect of this improvement is that the feed hopper is arranged on the opposite side of the first discharge port, which can prevent the rock and soil from being discharged along the first discharge port without being screened by the screen plate.

When the bottom end of the screen plate 3 rotates to the first discharge port 14, the rock is led out along the first discharge port 14 to the first collecting box 18. When the screened rock After falling onto the dust filter plate 20 on the first collecting box 18, the dust on the rock passes through the dust filter plate 20 and falls into the first collecting box 18, thereby realizing the separation of rock and dust. The sand passes through the sieve plate 3 and falls to the bottom of the screening cylinder 1, and slides along the second discharge port 17 into the second collecting box 19. When it is necessary to dredge the sieve plate 3, the through-hole brush 12 is driven to move up and down with the cooperation of the electric telescopic rod 11, and the through-hole brush 12 can dredge the mesh on the sieve plate 3. As the sieve plate 3 rotates, the entire sieve plate 3 can be fully cleaned.
