Description

Technical Field

[0001] The utility model relates to the technical field of soil transportation, in particular to a soil excavation and transportation mechanism. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. The shield construction method is that the tunnel boring machine constructs (lays) the "shield" (referring to the supporting segments) of the tunnel while excavating. It is different from the open construction method. Shield machines are generally divided into hand-dug shields, extrusion shields, semi-mechanical shields (local air pressure, global air pressure), and mechanical shields (open-chest cutting shields, pneumatic shields, slurry pressure shields, earth pressure balance shields, mixed shields, and special-shaped shields) according to their working principles. When the shield machine is working, equipment is needed to transport the soil.

[0003] However, when many shield machines use soil conveying devices, the soil transported will accumulate at the outlet of the transport device. If there is no personnel to deal with it in time, the soil will pile up higher and higher, which may block the outlet and affect the normal use of the device.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a new soil excavation and conveying mechanism to solve the problem of soil piling up higher and higher in the prior art. When the soil falls, the soil can be moved left and right through the toggle plate to avoid it piling up in one place, which is very efficient.

[0006] To achieve the above purpose, the technical solution of this utility model is as follows:

[0007] The utility model provides a soil excavation and conveying mechanism, comprising a conveying pipe, a conveying screw rod passing through the interior of the conveying pipe, a toggle mechanism provided on the top of the conveying pipe, and the toggle mechanism comprising a transmission assembly and a swing assembly;

[0008] The transmission assembly includes a motor, a rotating plate and a protruding rod located on the top surface of the conveying pipe, one end of the rotating plate is connected to the motor, and the other end is connected to the protruding rod;

[0009] The swing assembly includes a moving plate provided with a slide groove and a toggle plate. The protruding rod is located in the slide groove and slides left and right in the slide groove. The toggle plate is provided at the bottom of the moving plate.

[0010] Preferably, as a further implementable solution, the conveying mechanism also includes a clamping mechanism for clamping the assembly port located at the top of the conveying pipe, the clamping mechanism includes a connecting plate fixed on the top of the conveying pipe, a hydraulic rod is vertically arranged on the connecting plate, the output end of the hydraulic rod is fixedly connected to a lifting plate, the side of the lifting plate is fixedly connected to a connecting rod, the surface of the connecting rod is slidably connected to a clamping ring slidably connected to the connecting plate, and the clamping ring surrounds the assembly port.

[0011] Preferably, as a further implementable solution, the convex rod is arranged to deviate from the rotation center point of the rotating plate, and the convex rod and the rotating plate are arranged perpendicular to each other.

[0012] Preferably, as a further feasible solution, the moving plate and the shifting plate are parallel to each other and extend in the same direction.

[0013] Preferably, as a further feasible solution, the moving plate is arranged on the conveying pipe and is at the same height as the motor.

[0014] Preferably, as a further feasible solution, two groups of connecting rods are symmetrically arranged about the center point of the lifting plate, and the two groups of connecting rods are embedded in the inclined grooves provided on the side of the clamping ring and are slidably connected thereto.

[0015] Preferably, as a further feasible solution, the center point of the clamp ring and the assembly opening are located at the same point.

[0016] Preferably, as a further feasible solution, the clamping rings are symmetrically arranged in two groups about the center of the assembly opening.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By setting a toggle plate, in order to avoid the problem of soil accumulation at the outlet of the conveying pipe, the motor can be turned on to control the rotating plate to rotate, and the convex rod will rotate accordingly. When the convex rod rotates, it will slide along the inside of the chute and apply thrust to the moving plate, causing the moving plate to rotate around the connection with the conveying pipe, and the toggle plate fixedly connected to the moving plate will also swing left and right. When the soil falls, the toggle plate can be used to toggle the soil left and right to prevent it from piling up in one place.

[0019] By setting a clamping ring, in order to prevent the transmission pipe connected to the assembly port from loosening and causing soil leakage, the transport pipe can be stabilized by the clamping ring. When the transport pipe needs to be loosened, it is only necessary to open the hydraulic rod to pull the connecting rod downward. Because the connecting rod is embedded in the inclined groove inside the clamping ring, the connecting rod will apply a side thrust to the clamping ring by descending, causing the clamping ring to slide sideways along the top of the connecting plate, so that it no longer clamps and fixes the transport pipe. At this time, the transport pipe can be taken out from the inside of the assembly port. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to more clearly illustrate the technical solution of the present invention, it is described below in the form of specific embodiments.

[0030] Example 1

[0031] like Figure 1-Figure 2 As shown, this embodiment provides a soil excavation and conveying mechanism, including a conveying pipe 1, a conveying screw 11 passing through the conveying pipe 1, and a toggle mechanism 2 is provided on the top of the conveying pipe 1. The toggle mechanism 2 includes a transmission assembly 21 and a swing assembly 22;

[0032] The transmission assembly 21 includes a motor 211, a rotating plate 212 and a protruding rod 213 located on the top surface of the conveying pipe. One end of the rotating plate 212 is connected to the motor, and the other end is connected to the protruding rod 213.

[0033] The swing assembly 22 includes a moving plate 221 provided with a slide groove and a toggle plate 223 . The protruding rod 213 is located in the slide groove and moves left and right in the slide groove. The bottom of the moving plate 221 is fixedly connected to the toggle plate 223 .

[0034] Furthermore, the protruding rod 213 is set to deviate from the rotation center point of the rotating plate 212, and the protruding rod 213 and the rotating plate 212 are set perpendicular to each other. When the protruding rod 213 rotates, it will slide along the inside of the slide groove 222 and apply thrust to the moving plate 221, so that the moving plate 221 rotates around the connection with the conveying pipe 1.

[0035] Furthermore, the size of the chute 222 matches the size of the protruding rod 213, and the moving plate 221 forms a rotating structure at the top of the conveying pipe 1 through the protruding rod 213. By setting the chute 222, the chute 222 can avoid the problem of the protruding rod 213 getting stuck during movement.

[0036] Furthermore, the toggle plate 223 is located directly in front of the conveying pipe 1. When the moving plate 221 rotates, the fixedly connected toggle plate 223 will also swing left and right. When soil falls, the toggle plate 223 can be used to toggle the soil left and right to avoid it from piling up in one place.

[0037] Furthermore, the moving plate 221 and the toggle plate 223 are parallel to each other and extend in the same direction, which is more conducive to the toggle operation of the toggle plate to the greatest extent.

[0038] Furthermore, the moving plate 221 is arranged on the conveying pipe 1 and is at the same height as the motor 211, so as to ensure that the rotating plate located above the motor and the moving plate is horizontal, which is more conducive to the smooth progress of the transmission operation.

[0039] Example 2

[0040] like Figure 3-Figure 4 As shown, the above-mentioned conveying mechanism also includes a clamping mechanism located at the top of the conveying pipe 1 for clamping, and the clamping mechanism includes a connecting plate 3 fixed on the top of the conveying pipe, and a hydraulic rod 31 is vertically arranged on the top of the connecting plate 3, and the output end of the hydraulic rod 31 is fixedly connected to the lifting plate 32, and the side of the lifting plate 32 is fixedly connected to the connecting rod 33, and the surface of the connecting rod 33 is slidably connected to a clamping ring 34 slidably connected to the connecting plate 3, and the clamping ring 34 surrounds the assembly port 35.

[0041] Furthermore, two groups of connecting rods 33 are symmetrically arranged about the center point of the lifting plate 32. The two groups of connecting rods 33 are embedded in the oblique grooves provided on the side of the clamping ring 34 and are slidably connected thereto. Because the connecting rods 33 are embedded in the oblique grooves inside the clamping ring 34, the connecting rods 33 will apply a thrust to the clamping ring 34 to the side by descending, so that the clamping ring 34 slides to the side along the top of the connecting plate 3, so that it no longer clamps and fixes the transport tube.

[0042] Furthermore, the center points of the clamping ring 34 and the assembly port 35 are located at the same point, and the clamping ring 34 forms a clamping structure through the connecting rod 33. In order to prevent the transmission pipe connected to the assembly port 35 from loosening and causing soil leakage, the transport pipe can be stabilized by the clamping ring 34.

[0043] Furthermore, two groups of clamping rings 34 are symmetrically arranged about the center of the assembly opening 35. By providing two groups of clamping rings 34, the transport pipe can be clamped more firmly.

[0044] Working principle: When using the soil excavation and conveying mechanism, first, the soil is transferred into the conveying pipe 1 through the assembly port 35, and the transport screw 11 inside the conveying pipe 1 continuously rotates to transport the soil to the outlet. In order to avoid the problem of soil accumulation at the outlet of the conveying pipe 1, the motor 211 can be turned on to control the rotating plate 212 to rotate, and the protruding rod 213 rotates accordingly. When the protruding rod 213 rotates, it will slide along the inside of the slide groove 222 and apply thrust to the moving plate 221, so that the moving plate 221 rotates around the connection with the conveying pipe 1, and the toggle plate 223 fixedly connected to the moving plate 221 will also swing left and right. When the soil falls, the toggle plate 223 can be used to toggle the soil left and right to prevent it from piling up in one place.

[0045] In order to prevent the transmission pipe connected to the assembly port 35 from loosening and causing soil leakage, the transmission pipe can be stabilized by the clamping ring 34. When the transmission pipe needs to be loosened, it is only necessary to open the hydraulic rod 31 to pull the connecting rod 33 downward. Because the connecting rod 33 is embedded in the inclined groove inside the clamping ring 34, the connecting rod 33 will apply a side thrust to the clamping ring 34 by descending, causing the clamping ring 34 to slide sideways along the top of the connecting plate 3, so that it no longer clamps and fixes the transmission pipe. At this time, the transmission pipe can be taken out from the inside of the assembly port 35.

[0046] In summary, the conveying mechanism of the embodiment of the utility model has the following effects:

[0047] By setting a toggle plate, in order to avoid the problem of soil accumulation at the outlet of the conveying pipe, the motor can be turned on to control the rotating plate to rotate, and the convex rod will rotate accordingly. When the convex rod rotates, it will slide along the inside of the chute and apply thrust to the moving plate, causing the moving plate to rotate around the connection with the conveying pipe, and the toggle plate fixedly connected to the moving plate will also swing left and right. When the soil falls, the toggle plate can be used to toggle the soil left and right to prevent it from piling up in one place.

[0048] By setting a clamping ring, in order to prevent the transmission pipe connected to the assembly port from loosening and causing soil leakage, the transport pipe can be stabilized by the clamping ring. When the transport pipe needs to be loosened, it is only necessary to open the hydraulic rod to pull the connecting rod downward. Because the connecting rod is embedded in the inclined groove inside the clamping ring, the connecting rod will apply a side thrust to the clamping ring by descending, causing the clamping ring to slide sideways along the top of the connecting plate, so that it no longer clamps and fixes the transport pipe. At this time, the transport pipe can be taken out from the inside of the assembly port.

[0049] Finally, it should be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art will be able to make various modifications and improvements without departing from the principles and essence of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
