[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] This utility model provides, for example Figures 1-5 An automatic feeding and grading device for sand and gravel processing is shown, comprising:

[0046] Storage bin 100 is used to store sand and gravel.

[0047] Two striking devices 200 are provided, which are fixed on the front and rear sides of the storage box 100 respectively.

[0048] Screening frame 300 is fixed on the storage box 100. The screening frame 300 is struck by the striking device 200, causing the screening frame 300 to vibrate under the striking of the striking device 200.

[0049] Screening mesh 400 is fixed inside the screening frame 300. The screening mesh 400 is used to separate sand and gravel of different sizes.

[0050] The feed hopper 500 is positioned above the screening screen 400. A second support plate 510 is fixedly installed between the feed hopper 500 and the screening frame 300. The feed hopper 500 guides the sand and gravel material above the screening screen 400. The second support plate 510 supports the feed hopper 500 and ensures its stability during use.

[0051] During screening, the striking device 200 is activated to strike the screening frame 300, causing the screening frame 300 to vibrate the screening screen 400. Then, the sand and gravel are added to the screening screen 400 through the feed hopper 500, and the screening screen 400 drives the sand and gravel to vibrate for screening. The screened sand and gravel fall into the storage box 100 for storage.

[0052] In some embodiments of this utility model, the striking device 200 includes:

[0053] The receiving plate 210 is fixed on the storage box 100;

[0054] Guide cylinder 220, the guide cylinder 220 is fixed to the top of the receiving plate 210;

[0055] The support platform 230 is fixed on the top of the receiving plate 210, and the outer surface of the support platform 230 is in contact with the inner surface of the guide cylinder 220. The normal installation and fixation of the support platform 230 is ensured by the setting of the guide cylinder 220.

[0056] Telescopic rod 240 is fixed to the top of the support plate 210 and is located inside the support platform 230. The support plate 210 ensures the normal installation and fixation of the guide cylinder 220, support platform 230 and telescopic rod 240, and ensures the stability of the guide cylinder 220, support platform 230 and telescopic rod 240.

[0057] Compression spring 250 is fixed to the top of support platform 230;

[0058] The lifting plate 260 is fixed to the top of the compression spring 250 and slides up and down along the guide cylinder 220;

[0059] The striking head 270 is fixed to the top of the lifting plate 260;

[0060] Two strong magnets 280 are provided and are fixed to the bottom of the lifting plate 260 and the top of the telescopic rod 240 respectively. The outside of the strong magnets 280 is covered with an insulating plate, and the insulating plate is fixedly connected to the telescopic rod 240.

[0061] In use, the telescopic rod 240 is activated, causing the telescopic rod 240 to drive the strong magnet 280 to rise, so that the two strong magnets 280 attract each other and are fixed together. Then, the telescopic rod 240 drives the lifting plate 260 and the striking head 270 to fall. When the lifting plate 260 falls, it compresses the compression spring 250, causing the compression spring 250 to compress and store force. When the elastic force of the compression spring 250 is greater than the magnetic force of the two strong magnets 280, the compression spring 250 will drive the lifting plate 260 and the striking head 270 to rise, and the screening frame 300 will rise, causing the screening frame 300 to vibrate.

[0062] The telescopic rod 240 drives the lifting plate 260 and the striking head 270 to descend, and compresses the spring 250 to store energy when the lifting plate 260 descends, providing sufficient external force for the striking of the lifting plate 260 and the striking head 270.

[0063] The lifting plate 260 ensures the normal installation and fixation of the striking head 270, and also guides the lifting of the striking head 270.

[0064] The installation of two strong magnets 280 enables the lifting plate 260 to descend normally when the telescopic rod 240 descends, and the magnetic force decreases when the strong magnets 280 are moved away from the pole.

[0065] The support platform 230 ensures the proper installation and fixation of the compression spring 250, while also allowing the compression spring 250 to compress normally under stress.

[0066] In some embodiments of this utility model, the screening rack 300 includes:

[0067] Two first support plates 310 are provided and are fixed on the front and rear sides of the storage box 100 respectively.

[0068] The receiving frame 320 is hinged between two first support plates 310. The first support plates 310 support the receiving frame 320, ensuring its normal installation and use. The receiving frame 320 also installs and fixes the screening screen 400.

[0069] The pad 330 is fixed to the bottom of the receiving frame 320 and contacts the striking head 270;

[0070] The baffle plate 340 is fixed inside the receiving frame 320 and is fixed to the screening screen 400.

[0071] The first support plate 310 and the receiving frame 320 work together to restrict the swing of the receiving frame 320, so that the receiving frame 320 vibrates and drives the sand and gravel forward, avoiding excessive accumulation of sand and gravel that could clog the screening screen 400. When falling, the sand and gravel pass through the screening screen 400, which also speeds up the screening speed of the sand and gravel.

[0072] The pad 330 contacts the striking head 270, and the striking head 270 causes the receiving frame 320 to rotate and vibrate under the impact of the striking head 270.

[0073] The baffle plate 340 can block the sand and gravel, so that the sand and gravel can fall off the screen 400 when it is lifted.

[0074] In some embodiments of this utility model, an inclined plate 110 is fixedly installed on one side of the baffle plate 340, and the inclined plate 110 extends to one side of the storage box 100.

[0075] The inclined plate 110 guides the falling sand and gravel to a designated location.

[0076] The working method of this utility model:

[0077] In use, the telescopic rod 240 is activated, causing the telescopic rod 240 to drive the strong magnet 280 to rise, so that the two strong magnets 280 attract each other and are fixed together. Then, the telescopic rod 240 drives the lifting plate 260 and the striking head 270 to fall. When the lifting plate 260 falls, it compresses the compression spring 250, causing the compression spring 250 to compress and store force. When the elastic force of the compression spring 250 is greater than the magnetic force of the two strong magnets 280, the compression spring 250 will drive the lifting plate 260 and the striking head 270 to rise, and the screening frame 300 will rise, causing the screening frame 300 to vibrate.

[0078] Then, the sand and gravel are added to the screening screen 400 through the feed hopper 500, and the screening screen 400 drives the sand and gravel to vibrate for screening. The screened sand and gravel fall into the storage box 100 for storage.

[0079] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0080] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
