Description

Technical Field

[0001] The utility model relates to the field of sand and gravel processing, in particular to a movable frame for sand and gravel crushing. Background Art

[0002] A sand and gravel crusher is a mechanical device commonly used in the production of building materials, mainly used for crushing large stones into small granular sand and gravel. The movable crushing frame is mainly used for transporting sand and gravel, and transporting the sand and gravel into a crushing box for crushing.

[0003] Chinese Patent Publication No. CN217221623U discloses a sand and gravel crusher for preventing material accumulation, including a crushing box. A crushing roller is installed in the crushing box. A rotating plate is rotatably arranged in the crushing box. The rotating plate is located above the crushing roller. The rotating plate is inclined downward. The discharge port of the rotating plate is directly above the crushing roller. A conveying device is installed at the feeding end of the rotating plate. An elastic component is arranged below the rotating plate near the conveying device. A control switch for controlling the start and stop of the conveying device is installed on the crushing box. A trigger rod for triggering the control switch is installed at one end of the rotating plate far from the conveying device. When the sand and gravel on the crushing roller are crushed, the elastic component pushes the rotating plate to rotate in the reverse direction, and the control switch controls the conveying device to continue transporting the sand and gravel. The start and stop of the conveying device during the above sand and gravel crushing process do not need to be manually controlled, which is convenient and fast.

[0004] However, the above technical solution has the following deficiencies: iron filings will be entrained in the accumulated sand and gravel, which will not only reduce the purity of the sand and gravel, but also wear the crushing roller; when the sand and gravel are transported to the crushing roller, the sand and gravel generally accumulate in the same part of the crushing roller and cannot evenly fall between the crushing rollers, greatly increasing the crushing pressure and possibly causing the risk of the crushing roller being stuck. Summary of the Utility Model

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figures 1 - 4 As shown, the sand and gravel crushing mobile frame proposed in this embodiment includes a mounting seat 1, a dust removing mechanism and a screening mechanism; the dust removing mechanism is located on the mounting seat 1, and includes a support frame 5 arranged on the mounting seat 1 and an iron-absorbing assembly and a stirring assembly arranged on the support frame 5; the screening mechanism is located below the drop-out port of the conveying mechanism, and includes a fixed disk 15, a turntable 16 rotatably arranged on the fixed disk 15, and a driving assembly for driving the turntable 16 to rotate, the fixed disk 15 is provided with a first leakage hole 18, the turntable 16 is provided with a plurality of second leakage holes 23 distributed in a circular array, the turntable 16 is provided with a snap ring 17, the snap ring 17 and the fixed disk 15 are rotatably connected, the fixed disk 15 is provided with a baffle 19, the baffle 19 is located on the upper side of the first leakage hole 18, the baffle 19 facilitates the sand and gravel to fall from the first leakage hole 18, and the snap ring 17 is used to connect the fixed disk 15 and the turntable 16.

[0024] The magnetic suction assembly includes a second motor 6 arranged on a support frame 5, a first rotating shaft 7 rotatably arranged on the support frame 5, a connecting plate 8 arranged at the bottom end of the first rotating shaft 7, a first electromagnet 9 and a second electromagnet 10 arranged on the connecting plate 8, and a collecting box 11 arranged on the mounting base 1. The second motor 6 and the first rotating shaft 7 are drivingly connected.

[0025] The stirring assembly includes a third motor 12 arranged on the support frame 5, a second rotating shaft 13 rotatably arranged on the support frame 5, and a stirring blade 14 coaxially arranged on the second rotating shaft 13. The third motor 12 and the second rotating shaft 13 are drivingly connected.

[0026] When the sand and gravel raw materials are being conveyed, the third motor 12 drives the second rotating shaft 13 to rotate. The second rotating shaft 13 drives the stirring blade 14 to turn over the piled sand and gravel, preventing the iron filings pressed under the sand and gravel from being unable to be magnetically attracted. At the same time, the second electromagnet 10 is energized to adsorb the iron filings in the sand and gravel, improving the purity of the sand and gravel. When there are too many iron filings adsorbed under the second electromagnet 10, the second motor 6 is started to drive the first rotating shaft 7 to rotate. The first rotating shaft 7 drives the connecting plate 8 to rotate. The connecting plate 8 drives the first electromagnet 9 and the second electromagnet 10 to rotate, so that the first electromagnet 9 is located above the sand and gravel, and the second electromagnet 10 is located above the collection box 11. And the first electromagnet 9 is energized, and the second electromagnet 10 is de-energized. The iron filings on the second electromagnet 10 fall into the collection box 11. Through the repeated adsorption effect, both time is saved and the labor intensity is reduced.

[0027] The driving assembly includes a third rotating shaft 20 arranged on the turntable 16, a support column 27 arranged below the turntable 16, a fourth motor 21 arranged on the support column 27, and two horizontally arranged and meshing gears 22. The fourth motor 21 and one side gear 22 are drivingly connected, and the other side gear 22 is coaxially arranged on the third rotating shaft 20. A material receiving bucket 24 is arranged below the turntable 16. The material receiving bucket 24 is provided with a groove for the support column 27 to be embedded. The groove facilitates the removal and placement of the material receiving bucket 24 from below the turntable 16.

[0028] The turntable 16 is driven to rotate by the fourth motor 21. When the sand and gravel falls on the turntable 16, the sand and gravel moves from the center of the bottom surface of the turntable 16 to the outside under the action of centrifugal force. The smaller sand and gravel particles that meet the requirements fall through the second leakage hole 23, and the larger sand and gravel particles fall through the first leakage hole 18, realizing pre-screening of the sand and gravel before crushing, reducing the working duration of the crushing roller (not shown) and reducing the working load. The sand and gravel falling through the second leakage hole 23 enters the material receiving bucket 24.

[0029] Embodiment 2

[0030] As Figure 1 shown, the sand and gravel crushing mobile rack proposed in this embodiment, compared with Embodiment 1, in this embodiment, a conveying mechanism is arranged on the mounting seat 1. The conveying mechanism includes a first motor 2 arranged on the mounting seat 1, two roller shafts 3 rotatably arranged on the mounting seat 1, and a conveyor belt 4 for conveying sand and gravel. The conveyor belt 4 is sleeved on the two roller shafts 3. The roller shafts 3 are driven to rotate by the first motor 2, and the roller shafts 3 drive the conveyor belt 4 to drive, thereby conveying the sand and gravel.

[0031] Embodiment III

[0032] As Figure 1 and Figure 4 shown, for the sand and gravel crushing mobile frame proposed in this embodiment, compared with Embodiment I, in this embodiment, a material guiding mechanism is provided below the first leakage hole 18. The material guiding mechanism includes a material guiding frame 25 with a flaring portion that gradually increases from inside to outside at the bottom, and multiple rows of shunting columns 26 arranged on the material guiding frame 25, and the adjacent two rows of shunting columns 26 are staggered.

[0033] In this embodiment, when the sand and gravel with larger particles fall from the first leakage hole 18, they will fall on the material guiding frame 25. When the sand and gravel move downward along the inclined surface of the material guiding frame 25 until the flaring portion, the sand and gravel are shunted under the action of the shunting columns 26, ensuring that the sand and gravel falling between the two crushing rolls can be evenly distributed, improving the processing efficiency, and also reducing the risk of the crushing rolls being stuck during rotation.

[0034] The above has described in detail the embodiments of the present invention in conjunction with the drawings, but the present invention is not limited to this.
