[0026] 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.
[0027] In the existing technology, the main types of crushers include the following:
[0028] Jaw crusher: also known as jaw breaker, it has a simple structure, is easy to maintain and is inexpensive. It is suitable for crushing materials with medium to hard hardness, but it has low crushing efficiency and high wear and tear.
[0029] Cone crusher: also known as cone breaker, it has a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size. It is suitable for medium and fine crushing of various ores and rocks, but it has a complex structure, requires a lot of maintenance, and is expensive.
[0030] Impact crusher: also known as impact breaker, produces small and fine particles, suitable for crushing materials of varying hardness, with low energy consumption, high output, simple structure, and convenient maintenance.
[0031] Impact crusher: It has a large crushing ratio, good material particle shape, adjustable discharge particle size, high output and low consumption, but serious dust generation and easy wear of liners.
[0032] Hammer crusher: It has a simple structure, is easy to operate, is lightweight, and is easy to maintain, but the hammers wear out quickly, which increases production costs.
[0033] Compound crusher: The material falls vertically from the top of the machine into the high-speed rotating impeller. Under the action of high-speed centrifugal force, it collides and crushes with another part of the material at high speed. It is suitable for crushing various brittle materials.
[0034] Ring hammer crusher: suitable for crushing various brittle materials, such as coal, coal gangue, coke, etc.
[0035] These crushers each have their own advantages and disadvantages in industrial applications. The selection of a suitable crusher depends on the specific material characteristics and production requirements.
[0036] Impact crushers are mainly used in metallurgy, chemical industry, building materials, hydropower and other industries where material processing requires relocation. The mechanical structure of an impact crusher mainly includes the following parts:
[0037] Rotor: The rotor is the core component of the impact crusher, typically made of solid cast steel, making it robust and durable. Side and rear doors for maintenance and installation are mounted along the rotor's axis. Driven at high speed by an electric motor, the rotor utilizes its rotational inertia to impact and crush the ore.
[0038] Hammer plate: The hammer plate is rigidly connected to the rotor. When the rotor rotates, the hammer plate impacts and crushes the material. Hammer plates are generally made of high-chromium cast iron, high-manganese steel, or other wear-resistant alloy steel, and come in various shapes, such as long strips, T-shaped, and S-shaped, to meet different working requirements.
[0039] Impact plate: The impact plate withstands the impact of the material ejected by the hammer, causing the material to break upon impact. The broken material is then bounced back into the impact zone for further impact crushing. Impact plates are generally welded from steel plates and their surface is fitted with wear-resistant liners.
[0040] Frame: The frame consists of an upper frame and a lower frame, which are bolted together. The lower frame is fixed to the foundation and bears the weight of the entire machine. All parts inside the frame that come into contact with the ore are equipped with replaceable wear-resistant liners to ensure long-term stable operation.
[0041] Crushing chamber: Impact crushers typically have a large crushing chamber, allowing materials sufficient space to move and fully utilizing the impact force. A screen plate is installed inside the crushing chamber to separate fine and coarse materials.
[0042] Transmission Mechanism: The transmission mechanism of the impact crusher is simple, with the main shaft and rotor directly driven by an electric motor through pulleys to rotate at high speed. The main shaft is supported by rolling bearings in bearing seats on both sides of the frame, and is generally lubricated periodically with dry grease.
[0043] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0044] Reference Figures 1-5 This utility model provides a multi-level mineral crushing, screening, and conveying integrated machine, comprising:
[0045] Mobile vehicle body 1;
[0046] Crusher 2 is fixedly attached to the top of the mobile vehicle body 1;
[0047] The multi-layer first screen 3 is arranged at intervals and at an angle. The screen holes of the multi-layer first screen 3 decrease from top to bottom. The bottom discharge port of the crusher 2 is located directly above the high end of the top first screen 3. An inclined receiving plate 4 is arranged below the bottom first screen 3. A vibration component is arranged on the moving vehicle 1. The vibration component is used to drive the multi-layer first screen 3 and the receiving plate 4 to vibrate.
[0048] The multi-layer adjustable screen 5 is set one-to-one with the multi-layer first screen 3. The top of the adjustable screen 5 contacts the bottom of the first screen 3 on the corresponding layer. The first screen 3 is provided with a driving component, which is used to drive the adjustable screen 5 on the corresponding layer to move, so that the screen holes of the adjustable screen 5 completely overlap with the screen holes of the first screen 3 or have partial overlap.
[0049] In this embodiment, the mobile vehicle body 1 is a mobile chassis. One end of the mobile chassis is fixedly connected to a connecting hook. When moving, the front of the vehicle (not shown in the figure) needs to be hinged to the connecting hook on the mobile chassis (the specific technology is existing and will not be described in detail here), so that the front of the vehicle can drive the mobile vehicle body 1 to move. When it moves to the designated position, the front of the vehicle is separated from the mobile vehicle body 1 and the front of the vehicle leaves the construction site.
[0050] During screening, the screen openings of the adjustable screen 5 partially overlap with those of the first screen 3, and the size of the overlapping portion decreases from top to bottom, thereby achieving multi-level screening. After a period of use, the adjustable screen 5 is moved by the drive component, so that the screen openings of the adjustable screen 5 completely overlap with those of the first screen 3, which facilitates the falling off of stuck ore and reduces clogging.
[0051] In this embodiment, the crusher 2 is an impact crusher. A guide chute 18 is fixedly connected to the feed inlet of the impact crusher. The mineral to be crushed is added to the inlet of the impact crusher through the guide chute 18 to achieve crushing.
[0052] An impact crusher is a type of crushing equipment that uses the principle of impact crushing to pulverize materials, resulting in finer crushing than a jaw crusher. The hammers of an impact crusher are mechanically clamped and firmly fixed to the rotor, possessing a large moment of inertia as they rotate with the rotor. Compared to a hammer crusher (where the hammers are suspended), the rotor of an impact crusher has greater momentum, making it suitable for crushing harder materials, while also consuming less energy (specific details are current technology and will not be elaborated here).
[0053] In some alternative embodiments, baffles 6 are fixedly connected to both sides of the first screen 3 and the receiving plate 4, and the driving assembly includes a plurality of first cylinders 7 fixedly connected to any one of the baffles 6. A connecting plate 8 is fixedly connected to the piston rod of the first cylinder 7, and the connecting plate 8 is fixedly connected to the adjusting screen 5.
[0054] The baffle 6 prevents minerals from falling from both sides, and the first cylinder 7 drives the adjusting screen 5 to move left and right.
[0055] In some alternative embodiments, a groove is provided at the bottom of the inner sidewall of the baffle 6 away from the first cylinder 7, and a plurality of sliders 9 are fixedly connected to the sidewall of the adjusting screen 5 away from the first cylinder 7. The plurality of sliders 9 are inserted into the groove and slidably connected to the groove.
[0056] By inserting the slider 9 into the groove, the adjusting screen 5 is supported, thereby improving the stability of the adjusting screen 5.
[0057] In some alternative embodiments, the two baffles 6 on both sides of the first screen 3 are in an inverted V-shape.
[0058] In some alternative embodiments, the vibration assembly includes a shock-absorbing base disposed on the top of the mobile vehicle body 1, a vertical plate 10 disposed on the shock-absorbing base, the high end of the first screen 3 and the baffle 6 being fixedly connected to the side wall of the vertical plate 10 respectively, and a plurality of vibration motors 11 being fixedly connected to the side of the vertical plate 10 away from the first screen 3.
[0059] In some alternative embodiments, the shock-absorbing base includes a base plate 12 fixed above the mobile vehicle body 1, a plurality of spring shock absorbers 13 fixed between the top of the base plate 12 and the bottom of the receiving plate 4, and a vertical plate 10 fixed to the receiving plate 4.
[0060] In this embodiment, multiple baffles 6 located on the same side are fixedly connected by a connecting plate, and the connecting plate is fixedly connected to the receiving plate 4 to improve stability.
[0061] The vibration of the vibrating motor 11 is transmitted to the multi-layer first screen 3. The minerals gradually vibrate and roll down from the high end to the low end on the first screen 3, thereby realizing vibrating screening. The impact on the moving vehicle body 1 is reduced by the spring shock absorber 13.
[0062] In some alternative embodiments, a guide plate 14 is fixedly connected to the discharge end of the first screen 3. The guide plate 14 extends out of the moving vehicle body 1. The lengths of the multiple guide plates 14 decrease sequentially from top to bottom. A partition plate 15 is fixedly connected to the bottom end of the guide plate 14 away from the first screen 3.
[0063] The minerals screened from the first screen 3 of each layer are discharged onto the guide plate 14, and then roll off the guide plate 14 to the outside of the moving vehicle body 1. A belt conveyor (not shown in the figure) can be installed at the bottom of the discharge end of each guide plate 14 outside the moving vehicle body 1 to transport the screened aggregate to the next station for use.
[0064] In some alternative embodiments, a plurality of second cylinders 16 are fixedly connected to the plate of the mobile vehicle body 1. The piston rod of the second cylinder 16 passes through the plate of the mobile vehicle body 1 and is fixedly connected to a support plate 17, which is located below the plate of the mobile vehicle body 1.
[0065] Once the mobile vehicle 1 reaches its destination, the second cylinder 16 is activated to lower the support plate 17, which then supports the ground. The mobile vehicle 1 remains stable by relying on the device's own gravity and support force.
[0066] In use, the mobile vehicle 1 is moved to the destination by the tractor unit, and then the tractor unit is separated from the mobile vehicle 1. The tractor unit leaves the construction site, and the minerals to be crushed are added to the crusher 2 for crushing. The crushed aggregate falls into the first screen 3. The vibration of the vibrating motor 11 drives the multi-stage first screen 3 to vibrate simultaneously. At this time, the screen holes of the first screen 3 and the adjusting screen 5 partially overlap, and the size of the partial overlap decreases from top to bottom, thereby realizing multi-stage screening. The screened aggregate enters the guide plate 14. The guide plate 14 is set with different lengths so that the aggregates of different levels fall to different positions. Belt conveyors can be set at the corresponding positions to transport the aggregates to the corresponding workstations.
[0067] After a period of use, the first cylinder 7 drives the adjustment screen 5 to move, so that the adjustment screen 5 and the screen holes of the first screen 3 are completely aligned, which facilitates the falling of stuck aggregate and reduces clogging.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0069] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
