Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a concrete crusher. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] In existing technologies, crushed stone blocks need to be added for mixing during concrete processing. These crushed stone blocks are produced by crushing large stones in a crusher. However, during the crushing process, because there is no obstruction at the feed inlet, the crushed stones are prone to flying out, causing injury to workers. This results in low safety and inconvenience. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when concrete processing requires the addition of crushed stone for mixing, the crushed stone is produced by crushing large stones in a crusher. However, during the crushing process, because there is no obstruction at the feed inlet, the crushed stones are easy to break out, causing injury to workers, resulting in low safety and inconvenience. Therefore, this invention proposes a crusher for concrete processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete crusher, comprising a crushing chamber, wherein a shielding mechanism is provided inside the crushing chamber, the shielding mechanism comprising an inclined guide frame and an inclined clamping plate, the inclined guide frame being disposed on one side of the inclined guide frame, the inclined clamping plate being located below the inclined guide frame, and side mounting plates being provided on both sides of the inclined clamping plate, one end of the side mounting plate being rotatably connected to the crushing chamber, a sliding rod being rotatably connected to the lower end of the side mounting plate, an inner plate being fixedly connected to the upper middle part of the sliding rod, a connecting plate being slidably connected to one end of the sliding rod, a rotating disk being fixedly connected to one side of the connecting plate, the rotating disk being rotatably connected to the crushing chamber, and a spring being fixedly connected between the inner plate and the connecting plate.

[0006] Preferably, side clips are fixedly connected to both sides of the inclined plate, and a side sliding groove is provided on one side of the side plate, and the side plate is slidably connected to the side sliding groove.

[0007] Preferably, the crushing chamber has flow guides on both sides, and the flow guides are located at the connection between the inclined plates.

[0008] Preferably, a T-shaped clamp is fixedly connected to the middle of one side of the crushing chamber.

[0009] Preferably, bolts are fixedly connected to both sides of the middle part of one side of the crushing chamber.

[0010] Preferably, a central sliding groove is provided in the middle of one side of the inclined guide frame, and fastening sliding grooves are provided on both sides of the middle of one side of the inclined guide frame. The central sliding groove is slidably connected to the T-shaped clamp rod, and the fastening sliding groove is fixedly connected to the bolt.

[0011] Preferably, a drive mechanism is fixedly connected to one side of the crushing chamber, a first protective cover is fixedly connected to the upper end of the drive mechanism, an inner pressure plate and a crushing blade are installed inside the crushing chamber, a transmission mechanism is installed between the output end of the drive mechanism and the shaft of the crushing blade, and a second protective cover is fixedly connected to the outer side of the transmission mechanism.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up the inclined plate and the inclined guide frame, when the stone is placed in the crushing chamber for crushing, the stone will squeeze the inclined plate, creating an opening between the inclined plate and the inclined guide frame. The stone enters the crushing chamber through the inclined surface, and then the inclined plate is lifted by the spring to close the opening. This method can prevent the stone from jumping out and increase safety. The inclined surface of the inclined guide frame can ensure that the stone falls accurately on the inclined plate, ensuring the stability of use.

[0014] 2. In this utility model, the T-shaped clamp is used to restrict the inclined guide frame. At the same time, this design allows the height of the inclined guide frame to be adjusted according to the size of the stones being processed, ensuring that stones of different sizes can enter the crushing chamber for crushing, thus improving adaptability. With the addition of the guide port, the inclined guide frame can be adjusted to its lowest position during rain and when the equipment is not in use, allowing rainwater to flow out from the guide port and preventing excessive moisture from entering the crushing chamber. This also prevents the crushing blades and inner pressure plate from rusting, ensuring a longer service life. The side sliding groove and side clamping strip are designed to be detachable, facilitating the replacement of the inclined clamping plate. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a concrete crusher, including a crushing chamber 1. The crushing chamber 1 is equipped with a shielding mechanism 5. The shielding mechanism 5 includes an inclined guide frame 51 and an inclined clamping plate 52. The inclined guide frame 51 is located on one side of the inclined guide frame 51, and the inclined clamping plate 52 is located below the inclined guide frame 51. Side mounting plates 53 are provided on both sides of the inclined clamping plate 52. One end of the side mounting plate 53 is rotatably connected to the crushing chamber 1. The lower end of the side mounting plate 53 is rotatably connected to a sliding rod 512. An inner plate 515 is fixedly connected to the upper middle part of the sliding rod 512. One end of the sliding rod 512 is slidably connected to a connecting plate 514. A rotating disk 55 is fixedly connected to one side of the connecting plate 514. The rotating disk 55 is rotatably connected to the crushing chamber 1. A spring 513 is fixedly connected between the inner plate 515 and the connecting plate 514.

[0023] The specific settings and functions of this embodiment are described in detail below. With the setting of the inclined plate 52 and the inclined guide frame 51, when the stone is placed in the crushing chamber 1 for crushing, the stone will squeeze the inclined plate 52, making an opening between the inclined plate 52 and the inclined guide frame 51. The stone enters the crushing chamber 1 through the inclined surface. Then, the inclined plate 52 is lifted by the spring 513 to close the opening. In this way, the stone can be prevented from splashing out, increasing safety. The inclined surface of the inclined guide frame 51 can ensure that the stone falls accurately on the inclined plate 52, ensuring the stability of use.

[0024] Example 2: Figure 1 - Figure 4As shown, side clamping strips 511 are fixedly connected to both sides of the inclined clamping plate 52. A side sliding groove 510 is provided on one side of the side mounting plate 53, and the side mounting plate 53 is slidably connected to the side sliding groove 510. A flow guide port 54 is provided on both sides of the crushing chamber 1, and the flow guide port 54 is located at the connection between the inclined clamping plate 52 and the inclined clamping plate 52. A T-shaped clamping rod 57 is fixedly connected to the middle of one side of the crushing chamber 1. Bolts 56 are fixedly connected to both sides of the middle of one side of the crushing chamber 1. A middle sliding groove 58 is provided in the middle of one side of the inclined guide frame 51. On both sides of the middle part of one side of the inclined guide frame 51, there are fastening grooves 59. The middle groove 58 is slidably connected to the T-shaped clamp rod 57. The fastening groove 59 is fixedly connected to the bolt 56. A drive mechanism 8 is fixedly connected to one side of the crushing chamber 1. A first protective cover 2 is fixedly connected to the upper end of the drive mechanism 8. An inner pressure plate 7 and a crushing blade 6 are installed inside the crushing chamber 1. A transmission mechanism 4 is installed between the output end of the drive mechanism 8 and the shaft of the crushing blade 6. A second protective cover 3 is fixedly connected to the outside of the transmission mechanism 4.

[0025] The overall effect of this embodiment is that the T-shaped clamp 57 restricts the inclined guide frame 51. At the same time, this design can adjust the height of the inclined guide frame 51 according to the size of the stone to be processed, so as to ensure that stones of different sizes can enter the crushing chamber 1 for crushing, which is more adaptable. With the setting of the guide port 54, the inclined guide frame 51 can be adjusted to the lowest position when it rains and the equipment is not in use, so that rainwater can flow out from the guide port 54, avoiding too much water from entering the crushing chamber 1, preventing the crushing blade 6 and the inner pressure plate 7 from rusting, and ensuring service life. With the setting of the side sliding groove 510 and the side clamping strip 511, the detachable design makes it easy to replace the inclined clamping plate 52.

[0026] The usage and working principle of this device are as follows: Adjust the position of the inclined guide frame 51 according to the size of the stone to be crushed, and fix the position of the inclined guide frame 51 with bolts 56. When in use, turn on the drive mechanism 8 to drive the crushing blade 6 to rotate, place the stone on the inclined plate 52, and through its inclined surface and its gravity, the inclined plate 52 rotates, opening between itself and the lower end of the inclined guide frame 51. The stone rolls into the crushing chamber 1, and the crushing blade 6 and the inner pressure plate 7 crush the stone. When it is necessary to disassemble the inclined plate 52, press the inclined plate 52 downward and pull it out.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
