[0027] 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.

[0028] To achieve the above-mentioned utility model objectives, such as Figure 2-8 As shown, this utility model provides a feed crushing device with automatic feed particle size determination function, including a support plate 1, support columns 5 fixedly arranged around the bottom surface of the support plate 1, a crushing mechanism 7 fixedly arranged on one side of the top surface of the support plate 1, multiple screening devices 3 arranged at the lower end of the support plate 1, a first discharge box 8 fixedly arranged at the bottom end of the screening device 3, a vibration motor 4 fixedly arranged on both sides of the screening device 3, and support legs 2 fixedly arranged on the bottom surface of the extended ends around the screening device 3.

[0029] The screening device 3 includes a housing 301. Three housings 301 are stacked sequentially via bottom and top sliding grooves and sliders. Each of the three housings 301 has slots on both sides of its outer wall, and each slot contains a limiting block 304. A second spring 305 is fixedly mounted on the bottom surface of each limiting block 304. Each of the three housings 301 has a screen 302 on its inner wall. A top baffle 303 is fixedly mounted on the top surface of the upper housing 301, and a first discharge box 8 is fixedly mounted on the bottom surface of the lower housing 301. Vibration motors 4 are fixedly installed on both sides of the three outer shells 301. Multiple adjustable latches 6 are fixedly installed on both sides between two adjacent outer shells 301. A guide plate 306 is fixedly installed on one side of each of the three outer shells 301. A corrugated pipe 307 is fixedly installed on one side of the bottom surface of each of the three guide plates 306. The four support legs 2 are connected to each other by a cross column. A first spring 201 is fixedly installed at the top of each of the four support legs 2. The top of each of the four first springs 201 is fixedly connected to the lower one of the three outer shells 301 around its perimeter.

[0030] Specifically, in operation, the operator first pours the feed into the feed box 703 located at the top of the device. The opening structure of the feed box 703 facilitates rapid feeding and effectively prevents material leakage. The feed falls into the crushing area set inside the frame 701. Then, the drive motor 705 is started, driving one of the crushing rollers 702 to rotate. The gears of one crushing roller 702 mesh with the gears of another crushing roller 702, and the feed is crushed by the squeezing force between the crushing rollers 702. The crushed material then flows out from the second discharge box 704 at the bottom of the frame 701 and enters the screening device 3 set below. T-shaped limiting blocks 304 are provided on both sides of the three screens 302. In use, the operator can insert the screen 302 along the T-shaped sliding grooves set on both sides of the outer shell 301. When the screen 302 slides down to the preset position, the limiting block 304 is moved to make the screen 302 continue to slide down along the sliding groove to the installation end point. After the screen 302 is fully placed in place, the limiting block 304 is released. Under the elastic force of the second spring 305, the limiting block 304 automatically resets, thus effectively fixing the screen 302. During subsequent maintenance or cleaning, the operator only needs to move the limiting block 304 and pull the screen 302 upward to easily disassemble the screen 302. The operation is simple and the maintenance efficiency is high.

[0031] To achieve the above-mentioned utility model objectives, such as Figure 1-8 As shown, the crushing mechanism 7 includes a frame 701. A feed box 703 is fixedly installed at the opening on the top surface of the frame 701. Two crushing rollers 702 are rotatably installed on both sides of the inner wall of the frame 701. A second discharge box 704 is fixedly installed at the lower end of the frame 701. A drive motor 705 is fixedly installed at the extended end of one side of the top surface of the support plate 1. The output end of the drive motor 705 is connected to one of the two crushing rollers 702. Gears are provided on one side of each of the two crushing rollers 702. The two gears mesh with each other. Multiple adjustable latches 6 include a fixing plate 601. A fixing hook 602 is fixedly installed on the top surface of one of the upper ends of the two fixing plates 601. A handrail 603 is provided on the top surface of one of the lower ends of the two fixing plates 601. An adjusting rod 604 is threadedly connected to the lower extension of the handrail 603. Adjusting bolts 605 are threadedly connected to the top ends of both sides of the adjusting rod 604. A collection box 9 is provided at the lower end of the first discharge box 8. The vibration motor 4 and the drive motor 705 are both connected to an external control power supply through connecting lines to realize start and stop control.

[0032] Specifically, after the feed enters the screening device 3, the crushed material falls sequentially onto a three-layer screen 302. These three screens 302 are installed in three independent housings 301, with each layer having a progressively smaller aperture, enabling efficient particle size classification. The activation of the vibration motor 4 causes the housing 301 to vibrate, driving the material to move on the screens 302, separating feed particles of different sizes layer by layer. During screening, particles larger than the aperture of the upper screen 302 remain on that layer; smaller particles penetrate the screen 302 and continue screening to the next layer. Feed that is too finely crushed and does not meet the particle size requirements falls into the first discharge box 8 after passing through the bottom screen 302, awaiting further processing. During discharge, the material is discharged through a corrugated pipe 307 connected to the first discharge box 8. The corrugated pipe 307 is adjustable in direction and can be retracted, allowing for flexible adjustment of the discharge direction to adapt to different collection methods, such as connecting to bag openings or... The collection box 9 improves discharge efficiency and ease of use. During the screening process, to ensure structural stability, the outer shell 301 and the support leg 2 are flexibly connected by the first spring 201, which can absorb the impact force generated by the operation of the vibration motor 4, enhance the stability of the entire device during operation, and prevent device displacement or structural damage. The three outer shells 301 are equipped with sliders on both sides, which can be slidably fitted in the corresponding slide grooves to realize the movable connection between the outer shells 301. When in use, the operator can loosen the adjustable lock 6 to quickly release the fixed state of the outer shell 301, and then push the outer shell 301 to one side along the slide groove direction to separate it from the slide groove between the adjacent outer shells 301. After the outer shell 301 is pushed out, the operator can further move the limit blocks 304 set on both sides of the outer shell 301 to unlock it, and then take out the internal screen 302 upwards for easy cleaning and maintenance. The operation is quick and the disassembly and assembly are convenient, which greatly improves the maintenance efficiency and convenience of the equipment.

[0033] Working Principle: In actual use, the operator first puts the feed to be crushed into the feed box 703 located above the device and starts the drive motor 705. Its output drives one of the crushing rollers 702 to rotate. The crushing roller 702 meshes with the other crushing roller 702 through a gear structure, rotating synchronously to form a relatively rotating crushing zone, thus achieving the crushing of the feed. The crushed material is discharged from the second discharge box 704 and falls into the screening device 3 below. This screening device 3 is driven by two vibrating motors 4, causing the entire device to vibrate and thus push the material to move and be screened on the screen 302. During the initial screening process, larger feed particles cannot pass through the aperture of the first layer of screen 302 and slide down along the guide plate 306, subsequently passing through... The corrugated pipe 307 at its end leads to the pre-placed collection container. Smaller particles fall through the first screen 302 to the second screen 302 for further screening and finer particle size classification. Even smaller particles fall to the third screen 302 for final screening. The finely crushed feed that is too small passes through the third screen 302 and enters the first discharge box 8, where it is collected in the collection box 9 at its lower end for subsequent processing. When the screen 302 needs to be replaced or cleaned, the operator can push the limiting blocks 304 on both sides of the outer shell 301 to release the limiting state of the screen 302 and lift or press it out, thus realizing the disassembly and maintenance of the screen 302 and greatly improving the operability and cleaning efficiency of the equipment.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
