Description

Technical Field

[0001] The utility model relates to the technical field of concrete crushing processing, in particular to a crushing device used for concrete production. Background Art

[0002] Concrete is a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. The term generally refers to cement as the binder, sand and stone as aggregates, mixed with water (which may contain admixtures and additives) in a specific proportion, and then mixed together. Cement concrete, also known as conventional concrete, is widely used in civil engineering. Currently, concrete processing requires a crushing process.

[0003] At present, it is necessary to manually feed concrete blocks into the crushing equipment body, which is labor-intensive. At the same time, if the size of the concrete blocks is large, they need to be manually beaten and dispersed before being fed into the crushing equipment body for processing (if large concrete blocks are directly crushed, it will be more difficult, not only the crushing effect will be reduced, but also the crushing parts will easily be worn, thereby reducing the service life of the crushing equipment body). The existing technology lacks a design that automatically detects the size of concrete blocks and automatically disperses and feeds them. Utility Model Content

[0004] The purpose of the present invention is to solve the problems raised in the above background technology, and then proposes a crushing device for concrete production.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A crushing device for concrete production includes a crushing device body, the crushing device body includes a feed hopper, and is characterized in that it also includes a conveyor belt, a mounting frame, a dispersion chamber, a telescopic member, a dispersion plate and a plurality of dispersion members.

[0007] The conveyor belt is arranged on one side of the crushing equipment body, and the end of the conveyor belt is above the feed hopper;

[0008] The mounting frame is arranged on the conveyor belt and a detection component is arranged on the mounting frame;

[0009] The dispersion chamber is arranged on the conveyor belt and is located on the right side of the mounting frame. An entrance and an exit are respectively arranged on the left and right sides of the dispersion chamber.

[0010] The telescopic parts are symmetrically arranged on the front and rear sides of the dispersion chamber;

[0011] The dispersion plate is connected to the telescopic member and is located inside the dispersion chamber;

[0012] The dispersion element is arranged on the dispersion plate.

[0013] Furthermore, the detection component is a CCD camera.

[0014] Furthermore, the dispersion pieces are high-strength alloy steel tips and are arranged in multiple rows on the dispersion plate, with the dispersion pieces in each row being equidistantly distributed.

[0015] In the above scheme, since a large number of dispersing parts are arranged and the contact area with the concrete block is small, a large pressure will be generated, thereby dispersing the large concrete block into several small pieces to improve the subsequent crushing effect.

[0016] Furthermore, a high-pressure air pump is provided on the dispersion chamber, and the high-pressure air pump is connected to a tee pipe. The remaining two pipes of the tee pipe are respectively connected to a suction pipe and a first suction hood fixed at the top of the dispersion chamber. The suction pipe is connected to a second suction hood on the side of the feed hopper and one end of the suction pipe is closed.

[0017] Furthermore, a first filter layer is provided on the first suction hood, and a second filter layer is provided on the second suction hood.

[0018] The above scheme can effectively suck the dust generated during the dispersion, feeding and crushing processes through the design of a high-pressure air pump, a three-way pipe, a suction pipe, a first suction hood and a second suction hood. The two parts of dust will adhere to the first filter layer and the second filter layer respectively.

[0019] Furthermore, a cylinder is provided on the dispersion chamber, and the cylinder is connected to a scraper in contact with the first filter layer.

[0020] In the above solution, since the first filter screen in the dispersion chamber is not easy to clean, a cylinder-driven scraper is added for automatic cleaning, thereby extending the service life of the first filter layer. The second filter layer is outside and can be directly replaced or cleaned.

[0021] Furthermore, door curtains are respectively provided in the entrance and the exit.

[0022] The above solution can further reduce the probability of dust in the dispersion room overflowing to the outside by designing a door curtain, thereby further improving the effect of preventing dust overflow without affecting the normal entry and outflow of concrete blocks.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] Compared with the existing technology, this device can automatically complete the process of automatically conveying and feeding concrete blocks into the crushing equipment, and can perform real-time photography and detection of the size of the concrete blocks during the conveying process. If the detection result shows that the size of the concrete block is large, the dispersion piece can be driven to contact the concrete block and then disperse it into several small pieces. The small pieces of concrete after dispersion will then start the subsequent crushing process. This can effectively alleviate the original phenomenon of large concrete blocks being difficult to crush, and at the same time extend the service life of the crushing piece, which has a better crushing effect on the concrete blocks and automatically completes the detection, dispersion and feeding processes.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0030] like Figure 1 and Figure 2 As shown, a crushing device for concrete production includes a crushing device body 2, the crushing device body 2 includes a feed hopper, a conveyor belt 1, a mounting frame 11, a dispersion chamber 12, a telescopic member, a dispersion plate 13 and several dispersion members.

[0031] The conveyor belt 1 is arranged on one side of the crushing equipment body 2, and the end of the conveyor belt 1 is above the feed hopper;

[0032] The mounting frame 11 is provided on the conveyor belt 1 and a detection element is provided on the mounting frame 11 (specifically, the detection element is a CCD camera, which is not shown in the figure);

[0033] The dispersion chamber 12 is provided on the conveyor belt 1 and is located on the right side of the mounting frame 11. An inlet 121 and an outlet 122 are provided on the left and right sides of the dispersion chamber 12 respectively.

[0034] The telescopic members are symmetrically arranged on the front and rear sides of the dispersion chamber 12 (the telescopic members are not shown in the figure, and are specifically one of an electric cylinder or an electric push rod);

[0035] The dispersion plate 13 is connected to the telescopic member and is located inside the dispersion chamber 12;

[0036] Dispersers are provided on the dispersion plate 13 to reduce the contact area with the concrete block and thereby increase the pressure (specifically, the dispersers are high-strength alloy steel tips 14 and are arranged in multiple rows on the dispersion plate 13, with the dispersers in each row being equidistantly distributed).

[0037] It should be noted that the pulverizing equipment body 2, the conveyor belt 1, the telescopic member and the detection member are all electrically connected to the controller, which is not shown in the figure.

[0038] The workflow of this utility model:

[0039] This device conveys concrete blocks to the interior of the crushing equipment body 2 at intervals via a conveyor belt 1 (the placement of the concrete blocks on the conveyor belt 1 is completed by a six-degree-of-freedom robotic arm, which is not shown in the figure and belongs to the prior art and its working principle will not be described). When the concrete blocks pass under the mounting frame 11, the CCD camera can capture the concrete blocks and then transmit the images to the controller. The controller then compares the images with the concrete block sizes in a pre-set standard image. The comparison results are divided into the following two situations:

[0040] (1) If the concrete block is smaller than the standard size, it means that the size of the concrete block is appropriate, and then the telescopic member does not work, and the concrete block can directly move and fall into the crushing equipment body 2 for processing;

[0041] (2) If it is larger than the standard size, it means that the size of the concrete block is large, and then the controller will feedback the signal to the telescopic parts, and then the two telescopic parts can drive the dispersion plate 13 to move synchronously toward the center so that the dispersion parts can contact the surface of the concrete block (in the process of dispersing large-sized concrete blocks, the conveyor belt 1 can be pre-set with a short shutdown period, or it can be continuously conveyed). Since the number of dispersion parts is large and the contact area with the concrete block is small, a large pressure will be generated, and then the large concrete block can be dispersed into several small pieces. Then, several small pieces of concrete move to the end of the conveyor belt 1 and fall into the crushing equipment body 2 for crushing process. At this time, the original phenomenon of large concrete blocks being difficult to crush can be effectively alleviated, thereby extending the service life of the crushing parts;

[0042] Compared with the existing technology, this device can automatically complete the process of automatically conveying and feeding concrete blocks into the crushing equipment, and can perform real-time photography and detection of the size of the concrete blocks during the conveying process. If the detection result shows that the size of the concrete block is large, the dispersion piece can be driven to contact the concrete block and then disperse it into several small pieces. The small pieces of concrete after dispersion will then start the subsequent crushing process. This can effectively alleviate the original phenomenon of large concrete blocks being difficult to crush, and at the same time extend the service life of the crushing piece, which has a better crushing effect on the concrete blocks and automatically completes the detection, dispersion and feeding processes.

[0043] In some embodiments, as Figure 1 and Figure 2 As shown, a high-pressure air pump 31 is provided on the dispersion chamber 12, and the high-pressure air pump 31 is connected to a tee pipe 32. The remaining two pipes of the tee pipe 32 are respectively connected to a suction pipe 34 and a first suction hood 33 fixed at the top of the dispersion chamber 12. The suction pipe 34 is connected to a second suction hood 36 on the side of the feed hopper, and one end of the suction pipe 34 is closed.

[0044] In a further optimization of the above embodiment, a first filter layer 35 is movably provided on the first suction hood 33, and a second filter layer 37 is movably provided on the second suction hood 36; this embodiment can effectively suck the dust generated during the dispersion, feeding and crushing processes through the design of the high-pressure air pump 31, the three-way pipe 32, the suction pipe 34, the first suction hood 33 and the second suction hood 36, and the two parts of the dust will be attached to the first filter layer 35 and the second filter layer 37 respectively.

[0045] In other embodiments, Figure 1 and Figure 2 As shown, a cylinder 41 is provided on the dispersion chamber 12, and the cylinder 41 is connected to a scraper 42 in contact with the first filter layer 35; since the first filter screen in the dispersion chamber 12 is not easy to clean, the cylinder 41 is added to drive the scraper 42 for automatic cleaning, thereby extending the service life of the first filter layer 35, and the second filter layer 37 is in the outside and can be directly replaced or cleaned.

[0046] In other embodiments, door curtains are respectively provided in the inlet 121 and the outlet 122, which are not shown in the figure. This embodiment can further reduce the probability of dust in the dispersion chamber 12 overflowing to the outside by designing the door curtains, thereby further improving the effect of preventing dust overflow without affecting the normal entry and outflow of concrete blocks.

[0047] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
