Abstract
Description
Technical Field
[0001] This invention relates to the technical field of crushing devices, and in particular to a crushing device based on tunnel construction. Background Technology
[0002] Tunnels are structures built underground, underwater, or in mountains to lay railways or build highways for motor vehicles. Based on their location, they can be divided into three main categories: mountain tunnels, underwater tunnels, and urban tunnels. Mountain tunnels are those that pass under mountains or hills to shorten distances and avoid steep slopes. During the construction of mountain tunnels, a large number of large rocks are piled up inside the tunnel, and crushers are needed to transport these large rocks to the outside of the tunnel.
[0003] While existing crushers can crush large rocks, they still have certain problems during use. For example, dust can spread to the surrounding area during the crushing process, reducing environmental quality. Patent CN218796184U discloses a tunnel construction crusher that starts a fan during crushing. After starting, the fan sucks in the dust and smoke floating outward from the discharge plate through the through holes. The dust and smoke are discharged into a fixed frame along with the air. When the air and dust flow outward from the fixed frame, they pass through a filter screen. The filter screen can purify and intercept the dust and smoke in the air, reducing the leakage of dust and smoke during crushing, protecting the health of construction workers and improving the construction environment inside the tunnel. However, in actual use, crushed rocks can get stuck in the air holes on the discharge plate, affecting the subsequent dust suppression effect and causing inconvenience. Summary of the Invention
[0004] The purpose of this invention is to provide a crushing device based on tunnel construction to solve the problems mentioned in the background art.

The crushing device based on tunnel construction is connected to an external water source and uses spraying to reduce dust generated during crushing, thereby preventing dust from spreading. 3. The tunnel construction-based crushing device drives the auger to rotate through the drive mechanism, which in turn drives the fixed rod to rotate, thereby causing the insertion rod to slide back and forth, performing anti-blocking and unblocking protection work on the insertion hole, facilitating the discharge of spray water to the outside, and enabling solid-liquid separation treatment. 4. This crushing device based on tunnel construction seals the feed inlet with a cover, further improving the dust prevention effect; 5. The crushing device based on tunnel construction drives the water supply pipe to rotate through the crushing mechanism, and in conjunction with the cover to block the feed inlet, the spraying range is increased.

Detailed Implementation
[0019] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0021] In current technology, when a blower is activated during crushing, it draws in the dust and smoke drifting outward from the discharge plate through through-holes. The dust and smoke are then discharged into a fixed frame along with the air. As the air and dust flow outward within the fixed frame, they pass through a filter screen. This filter screen purifies and intercepts the dust and smoke, reducing dust leakage during crushing, protecting the health of surrounding construction workers, and improving the construction environment inside the tunnel. However, in actual use, crushed stones can get stuck in the air holes on the discharge plate, affecting subsequent dust suppression and causing inconvenience.
[0022] like Figure 1-4As shown, this embodiment of the invention provides a crushing device for tunnel construction, comprising: a frame 10 with a housing 11 fixedly connected to its inner side; a crushing mechanism 12 disposed on the frame 10 and inserted into the housing 11; a shell 20 fixedly connected to the bottom outlet of the housing 11; an auger 21 rotatably connected to the shell 20; a drive mechanism 22 fixedly connected to one side of the frame 10 and used to adjust the angle of the auger 21; an outlet 23 opened at the bottom of the shell 20; a water supply pipe 30 disposed inside the housing 11; a nozzle 31 fixedly connected to the outside of the water supply pipe 30; and a box 40 fixedly connected to the bottom of the shell 20; and a discharge port. A water inlet 41 is fixedly connected to the bottom of the box body 40 and communicates with the interior of the box body 40; a slide rail 42 is fixedly connected to the inside of the box body 40; a slider 43 is slidably connected to the slide rail 42; a connecting plate 44 is fixedly connected to the slider 43; an insertion rod 45 is fixedly connected to the outside of the connecting plate 44; an insertion hole 46 is opened at the bottom of the housing 20, and the housing 20 communicates with the box body 40 through the insertion hole 46; a fixing rod 48 is rotatably connected to the inside of the box body 40; a cam 49 is fixedly connected to the outside of the fixing rod 48; a transmission mechanism 47 is disposed on one side of the housing 20, and the auger 21 and the fixing rod 48 are connected by transmission mechanism 47 at their co-directional ends.
[0023] After placing the frame 10 in the designated position, the rocks generated during tunnel construction are moved to the side of the frame 10. One end of the water supply pipe 30 is connected to an external water supply mechanism (such as a water pump connected to a water source). With the help of an external drive device (such as an inclined or vertical conveyor), the rocks that need to be crushed are put into the box 11. Then, the crushing mechanism 12 and the drive mechanism 22 are activated. The crushing mechanism 12 crushes the rocks, which then fall into the shell 20. The drive mechanism 22 then drives the auger 21 to rotate, transporting the crushed stone to the discharge port 23, where it is directly discharged into a designated collection container or conveying equipment. During the crushing process, water flows into the water supply pipe 30 and is then sprayed onto the inside of the box 11 through multiple nozzles 31, achieving a dust suppression effect. Finally, the wastewater falls downward into the shell 20 and settles on the bottom surface inside the shell 20. The water flows into the box 40 through the insertion hole 46 at the bottom of the housing 20, and finally flows into the designated storage container through the drain hole 41 at the bottom of the box 40. At the same time, when the drive mechanism 22 is working, the fixed rod 48 is driven to rotate inside the box 40 through the transmission mechanism 47. While rotating, the cam 49 is driven to rotate. After the cam 49 contacts the connecting plate 44, it pushes the connecting plate 44 to slide up and down. While sliding, the slider 43 is driven to slide on the slide rail 42, which restricts the connecting plate 44 to slide only vertically. While the connecting plate 44 slides up and down, the insertion rod 45 is driven to slide up and down. When the insertion rod 45 slides upward, it pushes out the gravel blocking the insertion hole 46. Through the rotation of the auger 21, the gravel is directly transported to the side near the discharge port 23 to avoid the insertion hole 46 from being blocked and affecting the normal discharge of subsequent spray water.
[0024] Specifically, the crushing mechanism 12 consists of a motor, a crushing roller, and a gear set. By turning on the motor, it drives one crushing roller and a gear to rotate. At the same time, through the meshing transmission of the gear set, it drives the other crushing roller to rotate, so that the two crushing rollers rotate in opposite directions to crush the rock. This is existing technology and will not be described in detail.
[0025] Specifically, the drive mechanism 22 consists of a motor, a transmission wheel, and a transmission belt. By turning on the motor, it drives the auger 21 to rotate through the transmission wheel and the transmission belt. This is existing technology and will not be described in detail here.
[0026] Specifically, the transmission mechanism 47 consists of a transmission wheel and a transmission belt. When the auger 21 rotates, it drives a transmission wheel to rotate. Then, through the transmission belt, it drives the transmission wheel on the fixed rod 48 to rotate, ultimately causing the fixed rod 48 to rotate and thus realizing transmission. This is existing technology, so it will not be described in detail.
[0027] Furthermore, a baffle 32 is fixedly connected to the inner side of the housing 11, which serves to shield and protect the water supply pipe 30 and the nozzle 31.
[0028] Furthermore, the box body 40 has an inclined surface inside, which facilitates the concentrated flow of spray water to the drain outlet 41.
[0029] Furthermore, multiple cams 49 are provided, allowing multiple cams 49 to rotate simultaneously, thereby ensuring that the connecting plate 44 is subjected to uniform force and that the up-and-down sliding is more stable.
[0030] Furthermore, a cover 50 is rotatably connected to the box body 11, and a telescopic rod 51 is rotatably connected to the cover 50. The other end of the telescopic rod 51 is rotatably connected to the box body 11. Before loading, the cover 50 is rotated so that while it rotates on the box body 11, the telescopic rod 51 is pulled to extend and rotate. After loading is completed, the cover 50 is rotated in the opposite direction so that while the telescopic rod 51 retracts, the cover 50 covers the top opening of the box body 11, thus providing splash protection.
[0031] Furthermore, a sealing gasket 60 is provided at the bottom of the cover 50 to enhance the sealing performance.
[0032] Furthermore, the crushing mechanism 12 is provided with a connecting rod 70, and a connecting rod 71 is fixedly connected to one end of the water supply pipe 30. The connecting rod 71 and the connecting rod 70 are connected by a transmission mechanism 72. A fixed seat 73 is fixedly connected to the housing 11, and a connecting pipe 74 is fixedly connected to the inner side of the fixed seat 73. One end of the connecting pipe 74 is rotatably connected to and communicates with one end of the water supply pipe 30.
[0033] When the crushing mechanism 12 is working, it drives the connecting rod 70 to rotate. Then, through the transmission mechanism 72, it drives the connecting rod 71 to rotate, causing the water supply pipe 30 to rotate inside the housing 11. This causes the nozzle 31 to rotate as well, increasing the spraying area and cleaning the inside of the housing 11, thus improving its practicality. While the water supply pipe 30 is rotating, the angle of the connecting pipe 74 remains unchanged, so it does not affect the normal water supply operation of the external water supply equipment.
[0034] Specifically, one end of the water supply pipe 30 is connected to one end of the connecting rod 71 via bolts and a sleeve. The inner side of the sleeve is equipped with a bearing, and the outer side of the connecting rod 71 is rotatably connected to the sleeve via the bearing. One end of the water supply pipe 30 is fixedly connected to the sleeve. After the bolt on the sleeve is inserted into the connecting rod 71, the connecting rod 71 and the water supply pipe 30 are fixedly connected. When the bolt is inserted into the connecting rod 71, the crushing mechanism 12 works and can drive the water supply pipe 30 to rotate. Conversely, when the bolt is not inserted into the connecting rod 71, the crushing mechanism 12 works, and the angle of the water supply pipe 30 remains unchanged, thus improving practicality.
[0035] Furthermore, a sealing cap 80 is provided at the other end of the connecting pipe 74 to improve the sealing effect.
[0036] Furthermore, a protective cover 90 is fixedly connected to one side of the housing 11. The protective cover 90 shields and protects the transmission mechanism 72 during operation, thereby improving safety.
[0037] Furthermore, the connecting plate 44 has a non-circular cross-section to prevent impurities from remaining on the connecting plate 44 and to facilitate subsequent cleaning and maintenance.
[0038] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
