[0002] As we all know, with the continuous acceleration of urbanization, the amount of construction waste generated and discharged in cities is also growing rapidly. Construction waste refers to solid waste generated during the construction, reconstruction or demolition of buildings. According to the source of construction waste, it can be divided into construction waste and demolition waste. Crushing equipment is essential when processing these construction wastes.

[0003] The patent with application number CN202321583000.X discloses a construction waste crushing device, which includes a crushing box, a crushing mechanism is arranged in the inner cavity of the crushing box, a feed port is fixedly connected to the top of the crushing box, a screening box is fixedly connected to the bottom of the crushing box, an adsorption mechanism and a screening mechanism are respectively arranged in the inner cavity of the screening box, a dust collecting box is fixedly connected to the bottom of the screening box, the adsorption mechanism is arranged in the inner cavity of the screening box, the adsorption mechanism includes a second motor, the second motor is connected to a third rotating shaft, and a magnet is installed on the outer side of the third rotating shaft.

[0004] Although the device has the effect of shielding dust, the feed channel of the device is open, and the garbage will splash during the crushing period. The splashed garbage fragments will splash out from the open part of the feed channel and fall to the ground, increasing the subsequent cleaning workload. The splashed garbage fragments can easily hit the staff nearby, so the practicality is not very good and there is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model is a construction waste crushing device, comprising a crushing box 1, the middle part of the crushing box 1 is connected to a crushing roller 13 through a rotating shaft, the front parts of several rotating shafts are provided with gears 14, and they are meshed with each other, a second motor 16 is installed at the front part of one of the rotating shafts, and when the second motor 16 is started and the second motor 16 rotates, the connected rotating shaft is driven to rotate, and the meshed gear 14 drives the other rotating shaft to rotate, and drives the crushing roller 13 to rotate, and the garbage is crushed, a feeding pipe 2 is provided on the upper part of the crushing box 1, and the external garbage is added into the crushing box 1 through the feeding pipe 2, and the upper part of the feeding pipe 2 is provided with several threaded holes 3, several Bolts 4 are threadedly connected in each of the threaded holes 3, and the upper parts of several bolts 4 are threadedly connected with fixing plates 5. The fixing plates 5 are installed on the upper part of the feed pipe 2 by means of the threaded connection between the bolts 4 and the threaded holes 3. The right parts of the several fixing plates 5 are rotatably connected with the rotating rod 7 through the rotating shaft. The front part of the rotating rod 7 is installed with a first motor 6, and the upper part of the rotating rod 7 is provided with a shielding component. When the crushing roller 13 starts to crush the garbage, the first motor 6 is started, the first motor 6 is reversed, and the rotating rod 7 is driven to rotate, and then the shielding component is driven to horizontally shield the upper part of the feed pipe 2 to shield the pipe mouth of the feed pipe 2. The shielding component includes a top plate 8, and the left part of the top plate 8 is provided with There are several springs 9, a bottom plate 10 is arranged on the left of the several springs 9, and a protective pad 11 is arranged on the left of the bottom plate 10. When the crushing roller 13 is crushing garbage, the flying broken particles hit the protective pad 11 at one end of the bottom plate 10, and then are blocked to prevent flying out of the pipe mouth of the feed pipe 2. After a period of use, when the protective pad 11 is worn out to a certain extent, the bolt 4 can be unscrewed to repair the protective pad 11 at one end of the bottom plate 10. The protective pad 11 is made of flexible rubber material. The rubber itself has good elasticity and can buffer part of the impact force, thereby reducing the impact force on the bottom plate 10. The cross-section of the bottom plate 10 is arranged in an arc shape, which can contact the flying particles in multiple directions and buffer part of the impact force. The cross-section of the protective pad 11 is arranged in an arc shape, which can contact the flying particles in multiple directions and buffer part of the impact force. A support plate 12 is arranged on the right part of the upper part of the crushing box 1. When new garbage needs to be added, the first motor 6 is started to rotate forward, and the first motor 6 drives the rotating rod 7 to rotate, and then drives the shielding assembly to rotate forward to a horizontal state, so that one end of the top plate 8 is placed on the upper end face of the support plate 12. A discharge port 15 is arranged on the right part of the crushing box 1, and the crushed garbage is discharged through the discharge port 15.

[0025] In summary, when the construction waste crushing equipment is in use, after the worker adds garbage into the crushing box 1 through the feed pipe 2, the first motor 6 is started to reverse, the first motor 6 drives the rotating rod 7 to rotate, and then drives the shielding component to rotate to the left to a horizontal state. After one end of the top plate 8 contacts the upper part of the feed pipe 2, the first motor 6 is turned off. At this time, the bottom plate 10 and the protective pad 11 are in the feed pipe 2, and then the second motor 16 is started. The second motor 16 rotates, driving the crushing roller 13 to rotate, crushing the garbage, and the particles generated during the crushing hit the protective pad 11 during the splashing period, and then fall into the crushing box 1 to continue. Crushing, the crushed garbage is discharged to the outside through the discharge port 15. When the garbage in the feed pipe 2 is crushed, start the first motor 6 to rotate forward, the first motor 6 drives the rotating rod 7 to rotate, and then drives the shielding assembly to rotate forward to a horizontal state, so that one end of the top plate 8 is placed on the upper end surface of the support plate 12, and then continue to add garbage to the feed pipe 2 for crushing, and the crushing work is repeated in this way. When the protective pad 11 or the bottom plate 10 has a certain amount of wear and tear, the bolts 4 can be unscrewed, and the fixing plate 5 can be removed from the upper part of the feed pipe 2 for maintenance, and the new fixing plate 5 can be installed on the upper part of the feed pipe 2 to work again.
