Description

Technical Field

[0001] The utility model relates to a silt clearing device, in particular to a channel silt clearing device for a water conservancy project. Background Art

[0002] When the water flow in the channel is slow, a large amount of silt is likely to accumulate, causing the channel to be blocked, which requires dredging of the channel. Engineering machinery such as excavators are often used to dredge the channel using buckets.

[0003] For example, a channel dredging device disclosed in the Chinese patent publication number CN220247037U relates to the technical field of dredging buckets, including a bucket, a push plate is engaged with the inner wall of the bucket, and a connecting strip is fixedly connected to the upper side of the bucket, a driving motor is installed on the top outer wall of the bucket, and the output end of the driving motor extends to the inside of the bucket and is connected to a threaded rod, and a threaded groove matching the threaded rod is provided inside the connecting strip. The utility model is provided with a driving motor and a push plate. When dumping the silt inside the bucket, the staff can start the driving motor, thereby driving the push plate to move inside the bucket to quickly push out the silt stored inside the bucket. A filter plate and a connecting block are provided. When in use, the silt and river water can be classified by setting the filter plate to reduce the burden of the bucket during dredging, and the space utilization efficiency of the bucket can be improved. With the setting of the connecting block, the filter plate can be cleaned while the push plate moves.

[0004] Some problems were found during the use of the above-mentioned existing channel dredging device. First, during the dredging operation, the silt will fill the inside of the bucket, and a large amount of silt and impurities will easily enter the thread groove on the screw, causing the threaded rod to be unable to get stuck. At the same time, it will cause the threaded rod to wear more severely, and the threaded rod will be easily damaged after long-term use. Secondly, the bucket still uses common teeth, and there are a lot of gaps between the teeth. When the bucket digs the silt at the bottom of the channel, the silt will flow away from the gaps between the teeth, resulting in a certain amount of silt left at the bottom of the channel that is difficult to dig away. Utility Model Content

[0005] The purpose of the utility model is to provide a channel desilting device for a water conservancy project to solve the existing problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a channel dredging device for a water conservancy project, comprising a dredging bucket, a flap is arranged in the dredging bucket, a connecting shaft is fixedly installed on the flap, sealed bearings are embedded and installed on the inner walls of both sides of the dredging bucket, the sealed bearings and the connecting shaft cooperate with each other, a conical protective shell is fixedly installed on one side of the dredging bucket, a hydraulic motor is fixedly installed in the conical protective shell, the output end of the hydraulic motor is fixedly connected to the connecting shaft, and a shovel plate is welded under the dredging bucket and near the front end edge.

[0007] Preferably, a connecting ear is fixedly mounted on the dredging bucket.

[0008] Preferably, drainage holes are provided on the inner walls on both sides of the dredging bucket.

[0009] Preferably, a slag discharge groove is provided below the dredging bucket, and the slag discharge groove is communicated with the interior of the dredging bucket.

[0010] Preferably, the flap fits against the inner wall of the dredging bucket.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By replacing the traditional teeth with a shovel plate, the silt is easy to dig as a whole and has high fluidity. A certain amount of digging ability is sacrificed in exchange for a better shoveling effect. Compared with the existing device, it can effectively prevent the silt from flowing out of the gaps between the teeth.

[0013] 2. The drainage hole allows the mud and water inside the dredging bucket to flow out, avoiding a large amount of mud and water inside the dredging bucket that increases the burden on the excavator. Compared with the existing device, the through hole is set at the bottom, which can avoid the situation where a large amount of silt is accumulated at the bottom and the mud and water cannot be effectively discharged.

[0014] 3. Starting the hydraulic motor can drive the connecting shaft to rotate, and the rotation of the connecting shaft can drive the flap to rotate, so that the flap can be flipped out from the inside of the dredging bucket. The hydraulic system of the excavator is used to drive the hydraulic motor. Compared with the existing device, for silt with higher fluidity, the transmission using the connecting shaft is less affected by the silt.

[0015] 4. During the resetting of the flap, the flap will squeeze the silt between the flap and the silt removal bucket. Due to the strong fluidity of the silt, the compressed silt will be discharged from the slag discharge chute to prevent the silt falling between the flap and the silt removal bucket from interfering with the resetting of the flap.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides a technical solution: a channel dredging device for a water conservancy project, comprising a dredging bucket 1, a flap 6 is arranged inside the dredging bucket 1, a connecting shaft 7 is fixedly installed on the flap 6, sealed bearings 4 are embedded and installed on the inner walls of both sides of the dredging bucket 1, the sealed bearings 4 and the connecting shaft 7 cooperate with each other, a conical protective shell 10 is fixedly installed on one side of the dredging bucket 1, a hydraulic motor 8 is fixedly installed in the conical protective shell 10, the output end of the hydraulic motor 8 is fixedly connected to the connecting shaft 7, and a shovel plate 5 is welded below the dredging bucket 1 and near the front end edge.

[0022] In this embodiment, the traditional teeth are replaced by a shovel plate 5. Since the silt is easy to dig as a whole and has high fluidity, a certain digging ability is sacrificed in exchange for a better shoveling effect. Therefore, the front edge of the shovel plate 5 is beveled, and the whole is a long plate, which can better fit the bottom of the channel. During the dredging process, the silt at the bottom of the channel can be effectively dug out. At the same time, when dumping the silt, the connecting shaft 7 is matched with the sealing bearing 4 to make the flap 6 rotatably installed inside the dredging bucket 1. Starting the hydraulic motor 8 can drive the connecting shaft 7 to rotate, and the rotation of the connecting shaft 7 can drive the flap 6 to rotate, so that the flap 6 is flipped out from the inside of the dredging bucket 1. Figure 2 As shown, the silt adhered to the inside of the dredging bucket 1 can be turned out together, and the sealing bearing 4 itself has a certain sealing performance to prevent the silt from entering its interior.

[0023] In order to discharge the muddy water inside the dredging bucket 1, the device is implemented by the following technical scheme: a connecting ear 2 is fixedly installed on the dredging bucket 1, and drainage holes 3 are opened on the inner walls of both sides of the dredging bucket 1.

[0024] The connecting ear 2 is connected to the arm head of the excavator, and the drainage hole 3 can make the mud and water inside the dredging bucket 1 flow out, so as to avoid a large amount of mud and water inside the dredging bucket 1 increasing the burden on the excavator.

[0025] In order to achieve the purpose of normal resetting of the flap 6, the present device adopts the following technical solution: a slag discharge groove 9 is opened under the dredging bucket 1, the slag discharge groove 9 is communicated with the inside of the dredging bucket 1, and the flap 6 is attached to the inner wall of the dredging bucket 1.

[0026] During the process of discharging the silt inside the dredging bucket 1 by rotating the flap 6, the silt in other parts of the inner wall of the dredging bucket 1 that are not covered may slide to the bottom of the dredging bucket 1. During the process of resetting the flap 6, the flap 6 will squeeze the silt between the flap 6 and the dredging bucket 1. Due to the strong fluidity of the silt, the compressed silt will be discharged from the slag discharge trough 9, avoiding the silt falling between the flap 6 and the dredging bucket 1 and interfering with the resetting of the flap 6.

[0027] The working principle and use process of the utility model are as follows: when using the device, it is necessary to place the device in a suitable position, and after connecting it to the excavator through the connecting ear 2, it is necessary to connect the hydraulic pipeline of the excavator to the hydraulic motor 8, and control the dredging bucket 1 to enter the channel to dig out the silt. When dumping the silt, the hydraulic motor 8 is started by the hydraulic pressure of the excavator, and the hydraulic motor 8 will drive the flap 6 to rotate, so that the flap 6 can push out the silt inside the dredging bucket 1.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
