Description

Technical Field

[0001] This utility model relates to the field of concrete aggregate recycling technology, and in particular to a crushing device for recycling aggregates from waste concrete. Background Technology

[0002] The recycling of aggregates from waste concrete is an important process of resource reuse. By recycling aggregates from waste concrete, we can reduce the exploitation and consumption of natural resources and reduce environmental damage.

[0003] In the process of recycling waste concrete into sand and gravel, crushing equipment is needed to break down the waste concrete into particles suitable for reuse. Currently, traditional crushing equipment on the market often discharges the material directly onto the ground after crushing. This not only makes it difficult to collect the discharged material, but also generates a large amount of suspended dust, which is harmful to the working environment and workers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crushing device for recycling sand and gravel from waste concrete.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crushing device for recycling aggregates from waste concrete includes a support frame, a crushing device body fixedly mounted on the top of the support frame, a feeding pipe fixedly mounted on the bottom of the crushing device body, and a guide frame fixedly mounted below the support frame; two detachable collection bins are guided within the guide frame, each collection bin being adapted to the feeding pipe, and limiting components for fixing the collection bins are installed on the guide frame.

[0007] In addition, a preferred structure is that the bottom of the support frame is fixedly provided with a base plate by connecting columns, and the top of the base plate is fixedly connected to the guide frame by multiple support columns.

[0008] In addition, a preferred structure is that multiple side plates are fixedly provided on one side of the limiting member, and multiple limiting posts are fixedly and vertically provided at the bottom of each side plate.

[0009] In addition, a preferred structure is that each corresponding limiting post on the guide frame is fitted with a limiting hole, and the limiting hole is a through-hole.

[0010] In addition, a preferred structure is that a dustproof ring is fixedly fitted at the bottom of the discharge pipe, and the top of the collection bin is adapted to the dustproof ring.

[0011] In addition, a preferred structure is that a handle is fixedly provided on one side of the collection chamber, and the contact surface between the bottom plate and the collection chamber is made of a smooth material.

[0012] The beneficial effects of this utility model are as follows: the crushing device body can crush waste concrete blocks, and by using two collection bins to collect the crushed material alternately, not only can the material be continuously collected, but also the dust generated when the material is discharged can be reduced by the collection bins and dustproof rings.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-5 A crushing device for recycling aggregates from waste concrete includes a support frame 1. A crushing device body 11 is fixedly mounted on the top of the support frame 1, and a feeding pipe 12 is fixedly mounted on the bottom of the crushing device body 11. A guide frame 22 is fixedly mounted below the support frame 1. Two detachable collection bins 3 are guided within the guide frame 22. Both collection bins 3 are adapted to the feeding pipe 12, and limiting members 4 for fixing the collection bins 3 are installed on the guide frame 22.

[0021] The crushing device body 11 can crush concrete and discharge the crushed material from the discharge pipe 12. It is worth noting that the specific structure and operation of the crushing device body 11 are existing technologies that are currently available on the market, and they are not the main technical problems to be solved in this technical solution. Therefore, they will not be described in detail in this utility model.

[0022] The bottom of the support frame 1 is fixedly provided with a base plate 2 by connecting columns, and the top of the base plate 2 is fixedly connected to the guide frame 22 by multiple support columns 21.

[0023] The limiting member 4 has multiple side plates 41 fixedly installed on one side, and multiple limiting posts 42 are vertically fixed downwards at the bottom of each side plate 41. Limiting holes 221 are provided on the guide frame 22 corresponding to the limiting posts 42, and these holes 221 are through-holes. Through the fitting and locking between the limiting posts 42 and the limiting holes 221, and in conjunction with the limiting action of the support posts 21, the limiting member 4 can be fixed, thereby securing the two collection bins 3 and preventing displacement of the collection bins 3 during material collection.

[0024] The bottom of the discharge pipe 12 is fixedly fitted with a dustproof ring 121, and the top of the collection bin 3 is adapted to the dustproof ring 121. The contact parts between the dustproof ring 121 and the collection bin 3 are fitted with silicone parts to improve the sealing performance between the discharge pipe 12 and the collection bin 3.

[0025] Each collection chamber 3 has a handle 31 fixedly installed on one side, and the contact surfaces between the base plate 2 and the collection chamber 3 are made of smooth material. The handles 31 facilitate the movement of the collection chamber 3 by the user, and the smooth contact surfaces between the base plate 2 and the collection chamber 3 reduce the resistance during movement.

[0026] In this embodiment, the user simply pours the waste concrete blocks into the crushing device body 11, which then crushes the concrete blocks. The crushed material falls into the collection chamber 3 through the discharge pipe 12. Since one side of the collection chamber 3 is transparent, the user can observe its interior. Once the collection chamber 3 is full, it can be removed, and another collection chamber 3 can be placed below the discharge pipe 12. By using two collection chambers 3 to collect the material alternately, continuous collection is achieved, and the dust generated during discharge is reduced through the collection chambers 3 and the dustproof ring 121.

[0027] Furthermore, when the collection chamber 3 is full, the user simply needs to move the limiting member 4 upwards and pull it out, causing the limiting post 42 to leave the limiting hole 221, thereby releasing the limiting member 4 from fixing the collection chamber 3. The user can then pull out the collection chamber 3 at the bottom of the discharge pipe 12 and move the other collection chamber below the discharge pipe 12, thus enabling the replacement of the two collection chambers 3.

[0028] The user then simply pours the material out of the collected bin 3 and places it inside the guide frame 22 from the other side. Next, the user simply snaps the limiting member 4 onto the guide frame 22 again, and inserts the limiting post 42 on the limiting member 4 into the limiting hole 221. This locking action between the limiting post 42 and the limiting hole 221, combined with the limiting action of the support post 21, secures the limiting member 4 and prevents displacement of the two collected bins 3.

[0029] In this invention, the crushing device body 11 can be used to crush waste concrete blocks. By using two collection chambers 3 to collect the crushed material alternately, not only can the material be collected continuously, but also the dust generated when the material is discharged can be reduced by the collection chambers 3 and the dustproof ring 121.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
