[0036] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] It should be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] It should be noted that in the description of this utility model, the terms "connection" and "installation" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; direct connection or connection through an intermediate medium; mechanical connection or electrical connection. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0039] The utility model provides a stone crushing and iron removal device, referring to Figure 1 The stone crushing and iron removal device includes an installation frame 1, an iron mesh 2, an electromagnet 3 and an iron mesh driving mechanism 4, wherein: the iron mesh 2 is slidably mounted on the top of the installation frame 1; the electromagnet 3 is mounted on the iron mesh 2; the iron mesh driving mechanism 4 is mounted on the installation frame 1, which is used to drive the iron mesh 2 to move back and forth in the horizontal direction.

[0040] When the above-mentioned device is in use, the mounting frame 1 is moved so that the iron mesh 2 is erected above the gravel conveyor line 100 (or the gravel is moved below the iron mesh 2). When the device is powered on, the electromagnet 3 can attract iron objects in the gravel to the iron mesh 2, thereby achieving the purpose of removing iron from the gravel. The iron mesh drive mechanism 4 can drive the iron mesh 2 to move back and forth in the horizontal direction. This configuration can not only increase the iron attraction range of the electromagnet 3, but also remove the iron mesh 2 from above the gravel after a certain iron attraction is completed, so that the iron objects are placed next to the gravel, achieving continuous operation.

[0041] Continue to refer to Figure 1 , the iron mesh driving mechanism 4 includes:

[0042] A first driving member 41, which is a hydraulic cylinder or a pneumatic cylinder, wherein a cylinder body and a piston rod of the first driving member 41 are connected to the mounting frame 1 and the iron mesh 2 respectively;

[0043] The guide rail 42 is fixedly mounted on the mounting frame 1;

[0044] The slider is fixedly mounted on the iron mesh 2 and slidably connected to the guide rail 42 .

[0045] Specifically, there are two first drive members 41, one on each side of the mounting frame 1 and connected to either side of the iron mesh 2. The cylinder of each first drive member 41 is bolted to the mounting frame 1, and its piston rod is connected to one side of the iron mesh 2 via a joint. Two guide rails 42 are fixed to either side of the mounting frame 1. Each guide rail 42 is slidably mounted with a plurality of sliders fixed to the bottom of the iron mesh 2. When the piston rods of the first drive members 41 extend or retract, the iron mesh 2 moves synchronously with them, achieving horizontal reciprocating motion of the iron mesh 2.

[0046] In other embodiments, the first driving member 41 may also be replaced by a belt or chain transmission mechanism. The belt or chain transmission mechanism is a common linear drive mechanism and will not be described in detail here.

[0047] Continue to refer to Figure 1 The number of electromagnets 3 is multiple to increase the magnetic attraction to iron objects and improve the effect of crushing and removing iron. In this embodiment, an electromagnet 3 is fixed at each of the four corners of the iron mesh 2, and an electromagnet 3 is fixed in the middle of the iron mesh 2.

[0048] In order to protect the electromagnet 3 , a protective cover is installed on the iron mesh 2 to cover the electromagnet 3 .

[0049] In this embodiment, the mounting frame 1 is formed by welding profiles and / or plates. The mounting frame 1 includes a rectangular frame and a plurality of upright posts arranged below the rectangular frame, and the iron mesh 2 is slidably mounted on the rectangular frame.

[0050] As an optional embodiment, refer to Figure 2 and Figure 3 An iron-absorbing area and an iron-storing area are provided below the mounting frame 1. The iron mesh driving mechanism 4 is capable of driving the iron mesh 2 to move between the iron-absorbing area and the iron-storing area. In the above structure, the iron-absorbing area is used to place gravel containing iron objects, and the iron-storing area is used to place iron objects sucked out of the gravel.

[0051] The device operates in both an iron-attracting mode and an iron-discharging mode. In the iron-attracting mode, the mesh drive mechanism 4 moves the mesh 2 above the iron-attracting area, powering on the electromagnet 3. The magnetic attraction of the electromagnet 3 removes iron from the gravel. In the iron-discharging mode, the mesh drive mechanism 4 moves the mesh 2 above the iron-storing area, disconnecting the electromagnet 3. The iron on the mesh 2 naturally falls into the iron-storing area, achieving continuous operation.

[0052] Specifically, the iron net 2 is mounted above the gravel conveying line 100 through the mounting frame 1, and the gravel conveying line 100 can be a belt conveyor; an iron storage area is provided on one side of the gravel conveying line 100, and an iron storage frame 5 is provided at the iron storage area. Figure 2 When the device is in the iron-absorbing mode, the iron mesh driving mechanism 4 drives the iron mesh 2 to move above the gravel conveyor line 100, turns on the power of the electromagnet 3, and the iron objects are attracted to the iron mesh 2 by the magnetic attraction of the electromagnet 3. Figure 3 When the above device is in the iron release mode, the iron mesh driving mechanism 4 drives the iron mesh 2 to move above the iron storage frame 5, disconnects the power supply of the electromagnet 3, and the iron objects fall into the iron storage frame 5.

[0053] Reference Figure 4 In this embodiment, the bottom plate of the iron storage frame 5 is tilted relative to the horizontal plane, and an iron material outlet is provided on the lower side of the bottom plate. Below this iron material outlet is an iron material conveyor line 200. After iron objects fall into the iron storage frame 5, they slide down the bottom plate of the iron storage frame 5 and are discharged from the iron material outlet. They then fall onto the iron material conveyor line 200 and are transported to the iron material processing area. This arrangement facilitates the handling and processing of iron materials and reduces manual labor intensity.

[0054] As another optional embodiment, refer to Figure 5 , there is no iron storage area below the mounting frame 1, only an iron absorption area (the dotted line in the figure indicates the iron absorption area). During operation, the iron mesh drive mechanism 4 drives the iron mesh 2 to move back and forth horizontally above the iron absorption area to increase the iron absorption range. When the iron mesh 2 is covered with iron objects, the iron storage frame 5 is manually placed below the iron mesh 2 to collect the iron objects in the iron storage frame 5. This embodiment is suitable for large-scale crushed stone iron removal.

[0055] The above two embodiments can be selected according to actual usage requirements.

[0056] Reference Figure 6 and Figure 7 The stone crushing and iron removal device further includes a cleaning mechanism 6 for blowing air toward the iron mesh 2. Specifically, the cleaning mechanism 6 includes a slide 61 slidably connected to the mounting frame 1, a nozzle 62 fixed to the slide 61, and a second driving member 63 for driving the slide 61 to reciprocate in the vertical direction.

[0057] In this embodiment, the carriage 61 is slidably connected to one side of the mounting frame 1 via a guide rail block. Constrained by the guide rail block, the carriage 61 can move smoothly along a predetermined trajectory. The second drive member 63 is a hydraulic or pneumatic cylinder. The cylinder body of the second drive member 63 is bolted to the mounting frame 1, and the piston rod of the second drive member 63 is connected to the carriage 61 via a joint. Two second drive members 63 are provided, one on each opposite side of the carriage 61.

[0058] When it is necessary to clean the iron filings and dust on the iron mesh 2 and the electromagnet 3, first, the iron mesh driving mechanism 4 drives the iron mesh 2 close to the slide 61; then, the nozzle 62 sprays gas toward the iron mesh 2, and the iron filings and dust on the iron mesh 2 and the electromagnet 3 are blown off by the air blowing force; during the process of the nozzle 62 spraying gas, the second driving member 63 drives the slide 61 to move back and forth in the vertical direction to increase the spraying range of the nozzle 62.

[0059] In this embodiment, a plurality of nozzles 62 are arranged at intervals on the slide 61 to increase the cleaning range of the iron mesh 2 .

[0060] In summary, the crushed stone iron removal device provided by the present invention can be placed at the crushed stone conveying line 100. During the crushed stone conveying process, the device can absorb the iron objects in the crushed stone onto the iron mesh 2, thereby preventing the iron objects from being placed in the crushed stone processing equipment and causing damage to the processing equipment. When the iron mesh 2 is full of iron objects, the iron mesh driving mechanism 4 drives the iron mesh 2 to move to one side of the crushed stone conveying line 100, then the electromagnet 3 is powered off, and the iron objects on the iron mesh 2 fall off, and then the iron mesh driving mechanism 4 drives the iron mesh 2 to move back to the top of the crushed stone conveying line 100, thus achieving continuous line operation and ensuring the effect of crushed stone iron removal. In addition, the iron mesh driving mechanism 4 can drive the iron mesh 2 to move back and forth above the crushed stone conveying line 100 to increase the iron absorption area and meet various work requirements. The device is also provided with a cleaning mechanism 6 for blowing air toward the iron mesh 2, so as to automatically clean the iron mesh 2 regularly and reduce the workload of manual cleaning.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
