Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, and in particular to a construction waste crushing device for construction. Background Technology

[0002] For example, Chinese patent CN220803424U discloses a construction waste crushing equipment for construction. By feeding construction waste into the hopper, the hydraulic push rod drives the extrusion block to slide back and forth, pushing the large pieces of waste blocked by the baffle column to the inner wall of the hopper and crushing them. This makes it easier to avoid the chance of blockage during the conveying of the device due to the difficulty of accurately distinguishing the size and specifications of construction waste by humans. It also makes it easier to avoid the time and effort of manually moving large pieces of waste away for separate crushing.

[0003] The crushing equipment in the aforementioned application uses a hydraulic pusher to drive the extrusion block to crush construction waste. However, since most construction waste is concrete blocks and contains steel bars, which are relatively hard, simple extrusion crushing is insufficient to crush the concrete blocks. Furthermore, the steel bars and other hard objects mixed in the concrete blocks will affect the crushing effect and even damage the crushing device. Crushing the steel bars and other objects together will also result in a waste of resources. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a construction waste crushing equipment for construction, which solves the technical problems that the simple extrusion in the existing technology is insufficient to crush concrete blocks containing steel bars, and the method of crushing the steel bars together will also cause great waste of resources. It achieves the purpose of enhancing the crushing effect of construction waste, facilitating the classification and recycling of construction waste, and saving resources.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a construction waste crushing equipment for construction, including a jaw crusher, wherein the jaw crusher is equipped with a crushing and recycling mechanism for classifying and recycling the crushed construction waste.

[0006] The crushing and recycling mechanism includes a stationary jaw plate installed on a jaw crusher, and a movable jaw plate installed on the left side of the stationary jaw plate. The jaw crusher is equipped with a transmission assembly that drives the movable jaw plate to move. A rotating shaft is opened in the rotating hole of the jaw crusher, and a tilting block is installed on the rotating shaft. Electromagnets are installed in the mounting slots on both the left and right sides of the tilting block. A scraper is installed inside the jaw crusher and on the left side of the tilting block. A drive motor that drives the rotating shaft to rotate is installed on the jaw crusher. A rebar combing assembly for combing vertical rebar is provided on the right side of the stationary jaw plate. A bag removal assembly for removing shredded cloth bags contained in construction waste is provided on the stationary jaw plate.

[0007] A further improvement is that the movable jaw plate is installed obliquely on the left side of the stationary jaw plate, and the inner surfaces of both the stationary jaw plate and the movable jaw plate are arrayed with conical protrusions. The flipping block is located on the left side of the bottom discharge port formed by the stationary jaw plate and the movable jaw plate.

[0008] A further improvement is that the rebar sorting assembly includes a toggle shaft rotatably connected to a rotating hole in the stationary jaw plate, and a toggle plate fitted to the right side of the stationary jaw plate is mounted on the toggle shaft. An electromagnetic strip is installed in the mounting cavity in the toggle plate, and a toggle motor for driving the toggle shaft to rotate is mounted on the stationary jaw plate.

[0009] A further improvement is that the bag removal assembly includes a drive shaft rotatably connected to the upper and lower sides of the jaw crusher and extending into the stationary jaw plate. Rollers rotatably connected to the shaft grooves opened on the stationary jaw plate are installed on both the front and rear sides of the two drive shafts. A drive belt is rotatably connected to the two sets of vertically corresponding rollers, and multiple steel nails are arrayed on the drive belt.

[0010] A further improvement is that pulleys are installed on the rotating shaft and at the front ends of the two transmission shafts. The pulleys on the two transmission shafts are on the same plane and are connected by a transmission belt. A pulley on the same plane as the pulleys on the rotating shaft is added to the front end of the bottom transmission shaft, and a transmission belt is also connected between the two.

[0011] A further improvement is that a collection plate for collecting discarded shredded cloth bags is installed on the right side of the jaw crusher, and a slag screening plate for grading and screening the crushed construction waste is provided at the bottom of the discharge port.

[0012] By means of the above technical solution, this utility model provides a construction waste crushing device for construction, which has at least the following beneficial effects:

[0013] 1. This utility model uses a moving jaw plate that makes a circular swing in conjunction with a stationary jaw plate to squeeze and split the solidified waste. The conical protrusions on both plates can be embedded more deeply into the material pile, squeezing the material from multiple directions, effectively increasing the crushing force on the material, and guiding the material to be more evenly distributed in the crushing chamber, avoiding the formation of "dead zones", so that the material can be continuously crushed, thereby improving the overall crushing efficiency.

[0014] 2. This utility model generates magnetic attraction by energizing the electromagnet inside the rotating block, which attracts metals such as steel bars and iron sheets in the crushed material. These metals are then scraped off and collected by the scraper during the rotation process, thereby realizing the recycling of metal resources.

[0015] 3. This utility model uses a toggle motor to drive the toggle shaft to rotate, which in turn drives the toggle plate to swing in a fan shape along the side of the stationary jaw plate. During this process, the electromagnetic strip is energized and generates a magnetic attraction force, which causes the steel bars that are standing vertically in the crushing chamber to tilt over, thereby avoiding the steel bars standing vertically in the crushing chamber from affecting the crushing of construction waste.

[0016] 4. This utility model uses two drive shafts to rotate, which in turn drives the roller shaft to rotate, and then drives the drive belt to rotate. The steel nails installed on the drive belt pick up the packaging bag fragments in the crushing chamber and transport them upward along the drive belt to the right side of the stationary jaw plate, thus preventing the packaging bag fragments from being mixed with the concrete debris and affecting the physical properties of the recycled concrete.

[0030] 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.

[0031] Example 1

[0032] Given that simple extrusion in existing technologies is insufficient for crushing concrete blocks containing reinforcing steel, and that crushing the steel along with the concrete would result in significant resource waste, this embodiment provides a construction waste crushing device for building construction. Please refer to... Figures 1-6 This construction waste crushing equipment enhances the crushing effect of construction waste and facilitates its classification and recycling, thus saving resources. The equipment includes a jaw crusher 1, which is equipped with a crushing and recycling mechanism 2 for classifying and recycling the crushed construction waste. The crushing and recycling mechanism 2 crushes the construction waste and specifically sorts and recycles metals such as steel bars and sheet metal, thereby achieving resource recycling.

[0033] Since simple compression in existing technology is insufficient to crush concrete blocks containing reinforcing steel, and crushing the reinforcing steel along with it would also result in a significant waste of resources, this device is equipped with a crushing and recycling mechanism 2. The crushing and recycling mechanism 2 includes a stationary jaw plate 21 mounted on a jaw crusher 1, and a movable jaw plate 22 mounted on the left side of the stationary jaw plate 21. The jaw crusher 1 is equipped with a transmission assembly 23 that drives the movable jaw plate 22 to move. A rotating shaft 24 is located in a rotating hole on the jaw crusher 1, and a tilting block 25 is mounted on the rotating shaft 24. Electromagnets 26 are installed in the mounting slots on both the left and right sides of the tilting block 25. A scraper 27 is mounted inside the jaw crusher 1 and located on the left side of the tilting block 25. A drive motor 28 is mounted on the jaw crusher 1 to drive the rotating shaft 24 to rotate. The right side of the stationary jaw plate 21... A steel bar combing assembly 31 is provided to comb the steel bars in the vertical direction. A bag removal assembly 32 is provided on the stationary jaw plate 21 to remove the shredded cloth bags contained in the construction waste. The motor in the transmission assembly 23 drives the eccentric shaft to rotate, which in turn drives the movable jaw plate 22 installed on the eccentric shaft to swing around the eccentric shaft. The construction waste falling between the stationary jaw plate 21 and the movable jaw plate 22 is squeezed and split, thereby crushing the construction waste. Then, the drive motor 28 is started to drive the rotating shaft 24 to rotate, which in turn drives the tilting block 25 to rotate. At the same time, the electromagnet 26 in the tilting block 25 is energized to generate magnetic attraction force, which attracts the steel bars, iron sheets and other metals in the crushed material. During the rotation, they are scraped off and collected by the scraper 27, thereby realizing the recycling of metal resources.

[0034] The movable jaw plate 22 is installed at an angle to the left of the stationary jaw plate 21, and the inner surfaces of both the stationary jaw plate 21 and the movable jaw plate 22 are arrayed with conical protrusions. The conical protrusions can be embedded more deeply into the material pile, squeezing the material from multiple directions, effectively increasing the crushing force on the material, and guiding the material to be more evenly distributed in the crushing chamber, avoiding the formation of "dead zones", so that the material can be continuously crushed, thereby improving the overall crushing efficiency. The flipping block 25 is located on the left side of the bottom discharge port formed by the stationary jaw plate 21 and the movable jaw plate 22.

[0035] Since packaging bags may be solidified in the concrete block, if these shredded bags are crushed along with the concrete block, it will reduce the physical properties of the recycled concrete. Therefore, the device is also equipped with a bag removal component 32. The bag removal component 32 includes a drive shaft 321 rotatably connected to the upper and lower sides of the jaw crusher 1 and extending into the stationary jaw plate 21. Rollers 322 rotatably connected to the shaft grooves opened on the stationary jaw plate 21 are installed on the front and rear sides of the two drive shafts 321. A drive belt 323 is rotatably connected to the two sets of vertically corresponding rollers 322, and multiple steel nails 324 are arrayed on the drive belt 323.

[0036] Pulleys 33 are installed on the rotating shaft 24 and at the front ends of the two drive shafts 321. The pulleys 33 on the two drive shafts 321 are on the same plane and are connected by a drive belt 34. A pulley 33 on the front end of the bottom drive shaft 321 is also installed on the same plane as the pulleys 33 on the rotating shaft 24, and is also connected by a drive belt 34. When the drive motor 28 drives the rotating shaft 24 to rotate, the drive belts 34 on the pulleys 33 on the rotating shaft 24 and the bottom drive shaft 321 drive the bottom drive shaft 321 to rotate. The pulleys 33 on the two drive shafts 321 and the drive belts 34 inside them drive the two drive shafts 321 to rotate synchronously, thereby driving the roller shaft 322 to rotate, which in turn drives the drive belt 323 to rotate. The steel nails 324 installed on the drive belt 323 pick up the packaging bag fragments in the crushing chamber and transport them upward along the drive belt 323 to the right side of the stationary jaw plate 21, so as to avoid the packaging bag fragments from being mixed in with the concrete debris and affecting the physical properties of the recycled concrete.

[0037] A collection plate 35 is installed on the right side of the jaw crusher 1 to collect the discarded shredded cloth bags. A slag screening plate 36 is set at the bottom of the discharge port to classify and screen the crushed construction waste. The packaging bag fragments that are turned over to the right side of the stationary jaw plate 21 are scraped off and collected by the collection plate 35. The crushed concrete fragments are screened in three stages by the slag screening plate 36 to obtain three kinds of fragments with different coarseness, which are used to make different recycling materials, thereby realizing the crushing, classification and collection of construction waste.

[0038] Example 2

[0039] Because the reinforcing bars in larger pieces of concrete waste are quite long, they may stand vertically in the crushing chamber and be unable to fall, affecting the crushing and processing of construction waste. Therefore, based on Example 1, as... Figures 1-6 As shown, the device is also equipped with a rebar sorting assembly 31. The rebar sorting assembly 31 includes a toggle shaft 311 rotatably connected to a rotating hole in the stationary jaw plate 21. A toggle plate 312 is mounted on the toggle shaft 311 and fits against the right side of the stationary jaw plate 21. An electromagnetic strip 313 is installed in the mounting cavity in the toggle plate 312. A toggle motor 314 is mounted on the stationary jaw plate 21 to drive the toggle shaft 311 to rotate. When the toggle motor 314 is started, it drives the toggle shaft 311 to rotate, which in turn drives the toggle plate 312 on one side of the toggle shaft 311 to swing in a fan shape along the side of the stationary jaw plate 21. During this process, the electromagnetic strip 313 is energized and generates a magnetic attraction force, which drives the rebar standing vertically in the crushing chamber to tilt, thereby discharging the rebar from the crushing chamber and being attracted and recovered by the flipping block 25.
