DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Example 1:

1 to 9 , a municipal construction material crushing device includes: a main body component, a crushing component and a sorting component;

The main assembly is used to stably install the entire device to prevent it from shaking too much during the crushing process. The main assembly includes a counterweight base 1 and a screening box 2 fixedly connected to the top of the counterweight base 1;

The top of the screening box 2 is fixedly connected with a crushing box 3;

The crushing assembly is used to crush concrete blocks containing steel bars. The crushing assembly includes a fixed box 7 fixedly connected to one side of the crushing box 3 and two crushing rollers 8 rotatably connected between the inner walls of the crushing box 3. A first gear 9 fixedly connected to one crushing roller 8 is rotatably connected inside the fixed box 7. A second gear 10 fixedly connected to the other crushing roller 8 is rotatably connected on one side of the fixed box 7 adjacent to the first gear 9. A first motor 11 is fixedly connected inside the fixed box 7. The driving end of the first motor 11 is fixedly connected to the first gear 9. A partition 12 is fixedly connected inside the crushing box 3 and on both sides of the two crushing rollers 8.

In addition, the buffer assembly includes two first hydraulic buffers 13 fixedly connected to the inside of the crushing box 3 and adjacent to one side of a partition 12. The tops of the two first hydraulic buffers 13 are fixedly connected to a first buffer plate 14. The tops of the other partition 12 are fixedly connected to two second hydraulic buffers 15. The tops of the two second hydraulic buffers 15 are fixedly connected to a second buffer plate 16. The second buffer plates 16 and the first buffer plates 14 are both rotatably connected to a number of guide shafts 17.

A dust discharge assembly for sucking out dust inside the crushing box 3 is provided on the side of the crushing box 3 away from the fixing box 7;

The sorting assembly is used to separate and collect the crushed steel bars and concrete blocks. The sorting assembly includes a discharge port 5 fixedly connected to the bottom of the counterweight base 1 and a second motor 32 fixedly connected to the inside of the discharge port 5. The driving end of the top of the second motor 32 is fixedly connected to an electromagnetic shaft 33. The electromagnetic shaft 33 is respectively fixedly connected to a first electromagnetic plate 34, a second electromagnetic plate 35 and a third electromagnetic plate 36. The first electromagnetic plate 34, the second electromagnetic plate 35 and the third electromagnetic plate 36 are all provided with a plurality of through holes 37 of the same size.

In this embodiment, when the material enters the crushing box from the feed port 4 and is about to enter the crushing roller 8 area, the buffer assembly begins to function. The two first hydraulic buffers 13 support the first buffer plate 14 on the top, and the two second hydraulic buffers 15 on the other partition 12 also support the corresponding second buffer plate 16. The several guide shafts 17 rotatably connected on these buffer plates guide the material to approach the crushing roller 8 in a relatively smooth and uniform state, avoiding the problem of excessive impact force caused by the material directly hitting the crushing roller 8 due to gravity. It not only ensures that the crushing roller 8 can continue to work in a safe and stable stress state, reduces the risk of damage due to accidental impact, and extends its service life, but also enables the entire crushing process to be carried out in an orderly and efficient manner, thereby increasing the processing volume of municipal construction materials per unit time and meeting the demand for rapid crushing and processing of large amounts of construction materials in municipal construction;

At the same time, when the first motor 11 is started, the first motor 11 drives the first gear 9 to rotate, and the first gear 9 drives the two crushing rollers 8 to rotate in opposite directions through the meshing with the second gear 10, thereby crushing the reinforced concrete blocks put into the crushing box 3 through the feed port 4. Because the driving end of the first motor 11 is fixedly connected to the first gear 9, and the first gear 9 is connected to one of the crushing rollers 8, and at the same time, through the meshing action with the adjacent second gear 10, it drives the other crushing roller 8 to rotate synchronously, so that after entering the crushing box 3, the material can be squeezed and crushed from two opposite directions;

Furthermore, the crushed material enters the screening box 2. At this time, the second motor 32 is started to drive the electromagnetic shaft 33 to rotate. Through electromagnetic control of the first electromagnetic plate 34, the second electromagnetic plate 35, the third electromagnetic plate 36, etc., the crushed steel bars and concrete blocks are separated and collected by utilizing the difference in electromagnetic attraction. Materials with different magnetic adsorption characteristics will be collected at different positions, and the through hole 37 facilitates a certain degree of screening and falling of the material during the rotation process, ultimately achieving the purpose of sorting and collection.

Example 2:

3 to 7 , compared with the first embodiment, the dust removal assembly in this embodiment includes a bellows 18 fixedly connected to one side of the crushing box 3, a dust suction port 19 communicating with the crushing box 3 is provided inside the bellows 18, a filter 20 is fixedly connected to one side of the bellows 18, an electric fan 21 is fixedly connected to the side of the filter 20 away from the crushing box 3, and a protective frame 22 fixedly connected to the bellows 18 is provided on the outer side of the electric fan 21.

The ash cleaning component includes an ash discharge port 23 opened inside the bellows 18, and the bottom of the bellows 18 is fixedly connected to a storage box 24 connected to the ash discharge port 23, and the top of the storage box 24 is fixedly connected to a transmission box 25. One side of the storage box 24 is rotatably connected to a rotating shaft 26 fixedly connected to a crushing roller 8 and extending into the transmission box 25. A first bevel gear 27 is fixedly connected on the rotating shaft 26 and located inside the transmission box 25. A second bevel gear 28 is rotatably connected to the side of the transmission box 25 adjacent to the first bevel gear 27. The top of the second bevel gear 28 is fixedly connected to a reciprocating screw 29 rotatably connected to the bellows 18, and a cleaning scraper 30 is threadedly sleeved on the reciprocating screw 29. The scraping surface of the cleaning scraper 30 is in close contact with the filter screen 20, and a sealing door 31 is movably connected to the bottom of the storage box 24.

In this embodiment, when the electric fan 21 is started, negative pressure is formed in the bellows 18, and the dust inside the crushing box 3 is sucked out through the dust suction port 19. The dust is intercepted when passing through the filter 20, and the air is discharged through the electric fan 21, thereby achieving the function of sucking out and preliminarily filtering the dust inside the crushing box 3.

Furthermore, when the crushing roller 8 rotates, the first bevel gear 27 is driven to rotate through the rotating shaft 26, and the first bevel gear 27 drives the second bevel gear 28 to rotate, thereby rotating the reciprocating screw 29, driving the cleaning scraper 30 to reciprocate on the reciprocating screw 29, scraping off the dust adsorbed on the filter 20, and the dust falls into the storage box 24 through the dust discharge port 23. The bottom of the storage box 24 is movably connected with a sealing door 31, which is convenient for subsequent cleaning of the collected dust.
