[0026] The utility model provides a pipe and channel siltation cleaning device 1.
[0027] Combination Figure 1As shown, in one embodiment of the utility model, the pipe siltation cleaning device 1 includes a mounting bracket 10, a driving mechanism 30 and a reamer assembly 20; the mounting bracket 10 includes a connecting plate 11 and two mounting plates 12 connected to the two ends of the connecting plate 11; the two ends of the driving mechanism 30 are respectively mounted on the two mounting plates 12; the reamer assembly 20 includes a left reamer 21 and a right reamer 22, both of which are driven and connected to the driving mechanism 30, and are arranged in sequence between the two mounting plates 12 in a direction perpendicular to the mounting plate 12; the driving mechanism 30 drives the left reamer 21 and the right reamer 22 to rotate and cut the silt, so that the left reamer 21 transports the cut silt toward the right reamer 22, and the right reamer 22 transports the cut silt toward the left reamer 21.
[0028] In the embodiment of the utility model, the connecting plate 11 and the two mounting plates 12 arranged at both ends of the connecting plate 11 enclose an installation space with an opening on one side, and the driving mechanism 30 and the reamer assembly 20 are both installed in the installation space, and the reamer assembly 20 faces the side of the opening, so the mounting bracket 10 plays a protective role for the driving mechanism 30 and the reamer assembly 20. It can be understood that during actual canal dredging, the opening of the mounting bracket 10 should face the forward direction of canal cleaning, so the left reamer 21 and the right reamer 22 are arranged in sequence in a direction perpendicular to the mounting plates 12 on both sides, that is, the left reamer 21 and the right reamer 22 are arranged perpendicular to the forward direction, so that the left reamer 21 and the right reamer 22 can clean the canal at the same time, thereby improving the efficiency of canal dredging.
[0029] In the present application, the left reamer 21 and the right reamer 22 are driven to rotate by the driving mechanism 30, so that the spiral blades arranged on the outer periphery of the left reamer 21 and the right reamer 22 rotate, thereby achieving the effect of cutting and crushing the silt. At the same time, when the left reamer 21 rotates, the silt will be transported toward the right reamer 22 under the drive of its spiral blade, and when the right reamer 22 rotates, the silt will be transported toward the left reamer 21 under the drive of its spiral blade. Therefore, under the cooperation of the two, the silt after cutting and crushing is collected in the middle of the canal, that is, the middle of the canal siltation cleaning device 1, thereby avoiding the running wheels arranged on both sides of the canal siltation cleaning device 1, so that the running wheels can move forward smoothly in the canal, thereby improving the convenience of canal silt removal and the efficiency of cleaning.
[0030] Combination Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the spiral blades of the left reamer 21 and the right reamer 22 have different rotation directions, and the driving mechanism 30 drives the left reamer 21 and the right reamer 22 to rotate in the same direction.
[0031] In the embodiment of the utility model, the driving mechanism 30 drives the left reamer 21 and the right reamer 22 to rotate at the same time, and the rotation direction is the same. In order to realize that the sludge is collected between the left reamer 21 and the right reamer 22, according to the rule of left-hand rotation with the left hand and right-hand rotation with the right hand, the four fingers face the rotation direction, and the direction of the thumb pointing obtained is also the direction in which the sludge is transported. Therefore, the left reamer 21 can be designed to be left-handed, and the right reamer 22 can be designed to be right-handed, and the rotation direction of the left reamer 21 and the right reamer 22 can be designed to be counterclockwise with reference to the side facing the left reamer 21. Alternatively, the left reamer 21 can be designed to be right-handed, and the right reamer 22 can be designed to be left-handed, and the rotation direction of the left reamer 21 and the right reamer 22 can be designed to be clockwise with reference to the side facing the left reamer 21. All of the above can make the sludge cut and crushed by the left reamer 21 and the right reamer 22 be transported between the two.
[0032] In another embodiment, the outer periphery of the left reamer 21 and the right reamer 22 are provided with at least two circles of spiral blades, wherein the spiral blades on the side close to the mounting plate 12 are serrated, and the spiral blades on the side away from the mounting plate 12 are blade-shaped. The serrated spiral blades can be used to crush silt that is large in volume and difficult to cut. The silt crushed by the serrated spiral blades is transported to the blade-shaped spiral blades for a second cutting of the crushed silt, thereby further reducing the particle size of the silt to facilitate the cleaning of the silt.
[0033] Combination Figure 3 As shown, in one embodiment of the utility model, the driving mechanism 30 includes a supporting shaft 31, a hydraulic motor 32 and an oil-passing shaft 33. One end of the hydraulic motor 32 is connected to the supporting shaft 31, and the other end is rotatably connected to the oil-passing shaft 33. The ends of the supporting shaft 31 and the oil-passing shaft 33 away from the hydraulic motor 32 are respectively installed on two mounting plates 12. The oil-passing shaft 33 is used to provide hydraulic oil to the hydraulic motor 32. The left reamer 21 and the right reamer 22 are both formed with mounting channels 23 with two ends passing through. The left reamer 21 and the right reamer 22 are respectively sleeved on the outer periphery of the driving mechanism 30 and are drivingly connected to the hydraulic motor 32.
[0034] In the embodiment of the utility model, the support rotation and oil-passing shaft 33 can be installed on the mounting plates 12 on both sides by fasteners such as bolts and screws. At the same time, one end of the hydraulic motor 32 is the power output end and is rotatably connected to the oil-passing shaft 33. For example, a bearing ball can be arranged between the power output shaft and the oil-passing shaft 33, and the rotation connection with the oil-passing shaft 33 is realized by the ball. At the same time, the oil-passing shaft 33 can also provide hydraulic oil for the hydraulic motor 32. The other end of the hydraulic motor 32 is fixedly connected to the support shaft 31 so that the hydraulic motor 32 is stably installed between the mounting plates 12 on both sides. At the same time, the cross-sectional dimensions of the left reamer 21 and the right reamer 22 are gradually increased from the side close to the mounting plate 12 to the side away from the mounting plate 12, that is, the cleaning depth of the left reamer 21 and the right reamer 22 to the middle of the pipe channel is greater than the cleaning depth on both sides of the pipe channel, so as to better adapt to the dredging of the circular pipe channel.
[0035] Combination Figure 3 As shown, in one embodiment of the utility model, the reamer assembly 20 also includes a reamer support 50, which is arranged between the left reamer 21 and the right reamer 22 and is located in the installation channel 23. One end of the reamer support 50 is connected to the hydraulic motor 32, and the other end is connected to the left reamer 21 and the right reamer 22.
[0036] In the embodiment of the utility model, the hydraulic motor 32 drives the left reamer 21 and the right reamer 22 to rotate at the same time, and the left reamer 21 and the right reamer 22 are arranged adjacent to each other, and the two are bilaterally symmetrical. At the same time, bearings and balls are also arranged between the surfaces of the reamer support 50 and the hydraulic motor 32, and the bearings and balls support the reamer support 50, and also meet the requirement that the reamer support 50 can rotate relative to the outer peripheral surface of the hydraulic motor 32.
[0037] The reamer support 50 is arranged between the left reamer 21 and the right reamer 22, and is connected to the two. The connection method can be threaded connection, fastener connection or clamping, etc. At the same time, since the hydraulic motor 32 is placed horizontally in order to reduce the longitudinal structure volume, the driving mechanism 30 also includes a transmission bracket 321, one end of the transmission bracket 321 is connected to the reamer support 50, and the other end is connected to the power output shaft of the hydraulic motor 32. The power output shaft of the hydraulic motor 32 rotates, driving the transmission rod bracket to drive the reamer support 50, the left reamer 21 and the right reamer 22 to rotate.
[0038] Combination Figure 3 As shown, in one embodiment of the utility model, a bearing seat 80 is provided between the left reamer 21 and the supporting shaft 31 and between the right reamer 22 and the oil-passing shaft 33. The left reamer 21 is rotatably connected to the supporting shaft 31 via the bearing seat 80, and the right reamer 22 is rotatably connected to the oil-passing shaft 33 via the bearing seat 80.
[0039] In the embodiment of the utility model, it can be known from the above that the left reamer 21 and the right reamer 22 are connected to the hydraulic motor 32 through the reamer support 50. In order to improve the stability of the left reamer 21 and the right reamer 22, a bearing seat 80 is provided between the left reamer 21 and the support shaft 31, and the support shaft 31 supports the left reamer 21 through the bearing seat 80, and the left reamer 21 can also rotate relative to the support shaft 31 through the bearing seat 80. Similarly, the bearing seat 80 provided between the right reamer 22 and the oil-through shaft 33 can also achieve the above effect.
[0040] Combination Figure 3 As shown, in one embodiment of the utility model, a skeleton oil seal 60 is provided between the end of the left reamer 21 away from the right reamer 22 and the support shaft 31 , and a skeleton oil seal 60 is provided between the end of the right reamer 22 away from the left reamer 21 and the oil-passing shaft 33 .
[0041] In the embodiment of the utility model, the skeleton oil seal 60 disposed between the left reamer 21 and the support shaft 31 can seal the left reamer 21 and the support shaft 31, and the skeleton oil seal 60 disposed between the right reamer 22 and the oil shaft 33 can seal the right reamer 22 and the oil shaft 33, so as to prevent the sludge and sewage inside the pipe from entering the installation channel 23 inside the left reamer 21 and the right reamer 22, thereby improving the reliability of the driving parts such as the hydraulic motor 32 inside the installation channel 23. At the same time, the skeleton oil seal 60 uses oil film sealing, so it can also meet the requirements of the left reamer 21 and the right reamer 22 rotating relative to the support shaft 31 and the oil shaft 33.
[0042] Combination Figure 3 As shown, in one embodiment of the utility model, the pipe siltation cleaning device 1 also includes at least two sealing rings 70, at least one sealing ring 70 is arranged between the left reamer 21 and the bearing seat 80, and has an interference fit with the bearing seat 80 and the left reamer 21, and at least one sealing ring 70 is arranged between the right reamer 22 and the bearing seat 80, and has an interference fit with the bearing seat 80 and the right reamer 22.
[0043] In the embodiment of the utility model, the sealing ring 70 is arranged between the left reamer 21 and the bearing seat 80, and between the right reamer 22 and the bearing seat 80. As can be seen from the above, the oil film formed by the skeleton oil seal 60 is on the surface of the support shaft 31 and the oil-passing shaft 33. Therefore, in this embodiment, the sealing ring 70 is arranged between the left reamer 21 and the bearing seat 80, and between the right reamer 22 and the bearing seat 80, so as to further improve the sealing performance of the internal installation channel 23 of the left reamer 21 and the right reamer 22.
[0044] In one embodiment of the present invention, the spiral blades of the left reamer 21 and the right reamer 22 have the same rotation direction, and two drive mechanisms 30 are provided. The two drive mechanisms 30 respectively drive the left reamer 21 and the right reamer 22 to rotate in different directions.

At this time, according to the left-hand rule, with the direction facing the left reamer 21 as a reference, the rotation direction of the left reamer 21 is counterclockwise, and the rotation direction of the right reamer 22 is clockwise; or the left reamer 21 and the right reamer 22 can also be right-handed. At this time, according to the right-hand rule, the rotation direction of the left reamer 21 is clockwise, and the rotation direction of the right reamer 22 is counterclockwise; the above structures can achieve the effect of transporting sludge to the middle of the canal.

The opening of the connecting plate 11 is located in the middle, that is, between the left reamer 21 and the right reamer 22. Therefore, when the sludge is cut and crushed by the left reamer 21 and the right reamer 22 and transported between the two, it can be discharged to the outside through the opening of the connecting plate 11, the mounting cylinder 40 and the sewage hose, thereby improving the convenience of sludge cleaning.
