Description

Technical Field

[0001] This application relates to the field of civil engineering equipment technology, specifically a stone crushing device for civil engineering. Background Technology

[0002] Civil engineering is a general term for the science and technology of constructing various land engineering facilities. Currently, a large amount of stone is needed when constructing or renovating roads, railways, and tunnels. However, the stones transported directly to the construction site are generally too large, which necessitates the crushing process.

[0003] According to Chinese patent announcement number: A stone crushing device for civil engineering, this utility model can draw clean water from the water tank into the metal pipe by starting the water pump, and spray it onto the surface of the stone by opening the nozzle. During the crushing process, it is not easy to cause dust to be carried up due to compression and cracking, thus reducing the phenomenon of dust generation during the crushing process, effectively solving the problem of dust flying, ensuring the normal construction of the project and the health of the workers.

[0004] The solution mainly involves using nozzles on the conveying device to apply water to the surface of the stones, thereby preventing dust from being generated when the crusher crushes the stones. However, when the conveyor belt on the conveying device transports the stones to the feed inlet of the crusher, it not only carries the stones but also the dust mixed in with them. When the dust comes into contact with water, it becomes damp and turns into mud that adheres to the surface of the conveyor belt. This increases the friction between the conveyor belt and the stones, leading to a heavier load on the conveyor belt, increased energy consumption, and may even cause accelerated wear of the conveyor belt.

[0005] Therefore, this application provides a stone crushing device for civil engineering to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a stone crushing device for civil engineering, which aims to solve the problem mentioned in the background art that when dust comes into contact with water, it will become damp and turn into mud that adheres to the surface of the conveyor belt, increasing the friction between the conveyor belt and the stone, thus increasing the burden on the conveyor belt.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a stone crushing device for civil engineering, such as... Figures 1-4 As shown, the stone crushing device includes a frame and a stone crusher 1 installed on the frame. A conveying device 4 is provided on one side of the frame. A water tank 2 is installed on the frame. A water pump 3 is installed on the water tank 2. A first support frame 41 and a second support frame 42 are symmetrically installed on the conveying device 4. Metal pipes 5 are provided on both sides of the conveying device 4.

[0025] A mud removal mechanism 6 is provided at the end of the conveying device 4 that is away from the crusher 1;

[0026] The mud removal mechanism 6 includes a support base 61 located at the lower end of the conveying device 4. A fixed frame 7 is installed on the upper end of the support base 61. A connecting plate 73 is installed on the fixed frame 7. An assembly plate 62 is installed at the end of the connecting plate 73 away from the fixed frame 7. Arms 64 are symmetrically installed on the upper end of the assembly plate 62. A cleaning roller 65 is installed between the two arms 64. A drive shaft 67 is fixedly installed at both ends of the cleaning roller 65. A servo motor 63 is installed on the upper end of the assembly plate 62. A sprocket is fitted on both the output end of the servo motor 63 and the drive shaft 67 at one end of the cleaning roller 65. The two sprockets are fitted together by a transmission toothed chain belt 66.

[0027] Since the mud on the conveyor belt does not solidify during the reciprocating motion of the conveyor belt after it has just come into contact with the dust-reducing water, it will be wiped off when it passes the cleaning roller 65. During the wiping operation, simply push the support base 61 to the predetermined position and adjust the cleaning roller 65 to the position that matches the bottom of the conveyor device 4. The brush on the cleaning roller 65 will then contact the surface of the conveyor belt of the conveyor device 4. When the servo motor 63 starts, it will drive the transmission shaft 67 to rotate the cleaning roller 65 through the transmission toothed chain belt 66, thereby cleaning the conveyor belt. This can prevent mud from accumulating on the conveyor belt and affecting the service life of the conveyor device 4, and also reduce the intensity of the cleaning work for maintenance personnel.

[0028] A splash guard 621 is fixedly installed on the upper end of the assembly plate 62. Slide rails 623 are symmetrically arranged on the upper end of the splash guard 621. A sieve comb plate 622 is arranged between the two slide rails 623. Several comb grooves are opened on the sieve comb plate 622.

[0029] The splash guard 621 installed on the assembly plate 62 provides a shield for the servo motor 63, preventing the cleaning roller 65 from splashing onto the servo motor 63 when wiping and cleaning mud on the conveyor belt. At the same time, it also provides support for the screen comb plate 622, so that the screen comb plate 622 can comb the mud pieces attached to the brush of the cleaning roller 65, preventing too much mud from adhering to the cleaning roller 65 and thus affecting the cleaning effect.

[0030] The inner side of the slide rail 623 is provided with a sliding groove, and the sieve comb plate 622 is slidably connected to the sliding groove on the slide rail 623.

[0031] The slide rail 623 has a groove, which allows the screen bar plate 622 to move along the path of the groove. Later, the screen bar plate 622 can be moved outward, making it convenient for workers to clean the screen bar plate 622.

[0032] The upper end of the slide rail 623 has a round hole, and the sieve plate 622 is fixed to the round hole on the slide rail 623 by a pin.

[0033] By opening a round hole in the slide rail 623, the sieve bar plate 622 can be fixed in the center position of the slide rail 623 by a pin. When the pin is removed, the sieve bar plate 622 can be moved freely along the slide rail 623.

[0034] Positioning rods 72 are symmetrically installed on the fixed frame 7. A threaded rod 71 that is rotatably connected to the fixed frame 7 is provided between the two positioning rods 72. A self-locking box 74 for connecting with the threaded rod 71 is installed at the upper end of the fixed frame 7. The self-locking box 74 is provided with a worm gear that is sleeved with the threaded rod 71 and a worm for meshing with the worm gear. A drive wheel 75 is fixedly installed at one end of the worm. The threaded rod 71 is threadedly inserted into the connecting plate 73. The connecting plate 73 is sleeved with the positioning rod 72.

[0035] The threaded rod 71 is mainly used to adjust the height of the assembly plate 62 and the cleaning roller 65 when the drive wheel 75 rotates. The freely adjustable height allows the brush on the cleaning roller 65 to contact the surface of the conveyor belt of the conveyor device 4. The positioning rod 72 plays a stabilizing role when the connecting plate 73 moves up and down, preventing the connecting plate 73 from shaking significantly during adjustment. The worm gear drive inside the self-locking box 74 can play a self-locking role.

[0036] The connecting plate 73 and the assembly plate 62 are fixed by purlins and bolts. Several casters 611 are evenly distributed at the lower end of the support base 61. Limiting plates for connecting with the first support frame 41 are fixedly installed on the sides of the support base 61.

[0037] The connecting plate 73 and the assembly plate 62 are fixed together by purlin support plate and bolts. The assembly plate 62 and the connecting plate 73 can be disassembled at any time later. The limiting plate installed on the side of the support base 61 is mainly used to connect with the first support frame 41 by a pin, thereby calibrating the position of the support base 61.

[0038] In use, a support base 61 is set at one end of the conveyor device 4 near the ground. The cleaning roller 65 is set on the support base 61. When the servo motor 63 on the assembly plate 62 is started, it drives the transmission toothed chain belt 66 and the cleaning roller 65 to rotate synchronously, thereby wiping and cleaning the conveyor belt on the conveyor device 4. Since the mud on the conveyor belt has just come into contact with the dust-reducing water, it will not solidify during the transmission process. Therefore, when the mud attached to the conveyor belt passes the cleaning roller 65, it will be wiped off, thereby achieving the cleaning operation of the conveyor belt. This can prevent mud from accumulating on the conveyor belt and affecting the service life of the conveyor device 4, and can also reduce the cleaning intensity of the maintenance personnel.

[0039] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
