Description

Technical Field

[0001] This utility model relates to the field of vibratory compaction stone pile construction technology, specifically a filling device for vibratory compaction stone pile construction. Background Technology

[0002] Vibro-compaction, also known as vibratory water-flushing, is a foundation reinforcement method developed from the principle of compacting sandy soil foundations through vibration with water. It was later applied to vibro-compaction stone pile installation in cohesive soil layers. Vibro-compaction is a foundation reinforcement method used to improve poor foundations and meet the requirements of building foundations. During vibro-compaction stone pile construction, the vibro-compactor is first driven to a predetermined depth to form a pile hole. Then, a filling device is used to fill the hole.

[0003] Although the filling device has control valves to regulate the feeding speed during filling, in actual construction, due to the different sizes and irregular shapes of the crushed stone, there may be accumulation or partial gaps during feeding. The conveying pipe is the channel for conveying crushed stone, and its diameter is limited. When there are many large stones in the crushed stone, they are easy to accumulate in the conveying pipe. When cleaning, the workers need to remove the stones from the discharge pipe one by one to solve the blockage problem. This method of cleaning takes a long time and is not very efficient. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a filling device for vibratory compaction of stone piles, which facilitates dredging and material discharge, and greatly improves work efficiency.

[0005] The technical solution provided by this utility model is as follows: A filling device for vibratory compaction of stone piles includes a vehicle body, a storage hopper rotatably connected inside the vehicle body, a discharge pipe penetrating the lower part of the storage hopper, a clearing zone on one side of the discharge pipe for dispersing stones blocking the discharge pipe, several support plates on the side wall of the storage hopper, a first hydraulic cylinder at one end of one of the support plates, and a sealing structure fixedly installed at one end of the first hydraulic cylinder; during operation, the sealing structure moves to the clearing zone, blocking the clearing zone, and stones in the storage hopper pass through the discharge pipe and the sealing structure; during cleaning, the first hydraulic cylinder drives the sealing structure away from the clearing zone, and stones blocking the discharge pipe are discharged from the clearing zone.

[0006] Furthermore, the enclosed structure is a baffle plate with an arc-shaped cross-section, and the sidewall of the baffle plate fits into the inner wall of the dredging area.

[0007] Furthermore, several first fixing plates are provided on the side wall of the storage hopper, and a first connecting rod is rotatably connected to the middle of the several first fixing plates. A second hydraulic cylinder is fixedly installed in the middle of the first connecting rod.

[0008] Furthermore, several second fixing plates are provided on the left side of the vehicle body, and a second connecting rod is rotatably connected to the middle of the several second fixing plates. The middle part of the second connecting rod and the lower part of the second hydraulic cylinder are fixed together.

[0009] Furthermore, a support rod is fixedly installed on the side wall of the discharge pipe, and the other end of the support rod is fixedly installed together with one of the support plates.

[0010] Furthermore, a control valve is installed on the discharge pipe.

[0011] Compared with the prior art, this utility model provides a filling device for vibratory compaction of stone piles, which has the following beneficial effects:

[0012] When the discharge pipe of this vibratory crushing stone pile construction filling device is blocked, the first hydraulic cylinder can be retracted to drive the baffle plate out of the unblocking area of ​​the discharge pipe. At this time, the area of ​​the unblocking area is much larger than the opening area of ​​the discharge pipe. The stones blocked in the discharge pipe will fall out from the unblocking area, which facilitates the unblocking work of the staff and improves the work efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model discloses a filling device for vibratory compaction of stone piles, comprising a vehicle body 1, with a storage hopper 2 rotatably connected inside the vehicle body 1. In one embodiment, a connecting rod is rotatably connected to the inner side wall of the vehicle body 1 via a bearing, and the connecting rod and the storage hopper 2 are fixedly arranged together. Alternatively, a smooth circular hole with the same outer diameter as the connecting rod can be opened on the side wall of the vehicle body 1, allowing the connecting rod to rotate within the circular hole, thus rotatably arranging the vehicle body 1 and the storage hopper 2. Workers transport stone materials into the storage hopper 2 for storage, and then push the vehicle body 1 to the side of the pile hole. A discharge pipe 3 is connected through the lower part of the storage hopper 2, and a control valve 10 is installed on the discharge pipe 3. When the control valve 10 is opened, the stones in the storage hopper 2 are discharged into the pile hole through the discharge pipe 3. A clearing zone 4 is provided on one side of the discharge pipe 3. The discharge pipe 3 discharges stones. When stones of various sizes become blocked in the discharge pipe 3, the blocked stones are discharged to the outside through the clearing zone 4, facilitating cleaning. Several support plates 5 are provided on the side wall of the storage hopper 2. One end of one support plate 5 is equipped with a first hydraulic cylinder 6. A closed structure is fixedly installed at one end of the first hydraulic cylinder 6. When it is necessary to transport materials such as stones into the pile hole, the first hydraulic cylinder 6 extends, driving the closed structure to move to the clearing zone 4, blocking the clearing zone 4, and forming a complete pipeline with the discharge pipe 3. The stones in the storage hopper 2 pass between the discharge pipe 3 and the closed structure and then enter the pile hole. When the discharge pipe 3 becomes blocked, the first hydraulic cylinder 6 is activated. The first hydraulic cylinder 6 retracts, driving the closed structure away from the clearing zone 4, no longer blocking the clearing zone 4, and the blocked stones in the discharge pipe 3 are discharged from the clearing zone 4.

[0020] The closed structure is a baffle plate 7. The cross-section of the baffle plate 7 is arc-shaped. The arc-shaped baffle plate 7 is located in the dredging area 4 and can be used with the discharge pipe 3 to form a complete pipe body. The side wall of the baffle plate 7 fits into the inner wall of the dredging area 4, so that when the baffle plate 7 is in the dredging area 4, it can completely block the dredging area 4 and prevent sand and other impurities in the stones from seeping out from the gap between them.

[0021] Several first fixing plates are provided on the side wall of the storage hopper 2. A first connecting rod is rotatably connected to the middle of the several first fixing plates. A circular hole with the same diameter as the first connecting rod is provided on the first fixing plate. The first connecting rod rotates in the circular hole, or the first connecting rod is rotatably set with the first fixing plate through a bearing. A second hydraulic cylinder 8 is fixedly installed in the middle of the first connecting rod. When the second hydraulic cylinder 8 is started, the second hydraulic cylinder 8 retracts, driving the storage hopper 2 to rotate in the vehicle body 1, causing the discharge pipe 3 to tilt upward, so that the stones inside the storage hopper 2 roll away from the discharge pipe 3, making it easier to clear the discharge pipe 3.

[0022] The left side of the vehicle body 1 is provided with several second fixing plates, and the middle of the several second fixing plates is rotatably connected to a second connecting rod. The second fixing plate is provided with a circular hole with the same diameter as the second connecting rod. The second connecting rod rotates in the circular hole, or the second connecting rod is rotatably set with the second fixing plate through a bearing. The middle part of the second connecting rod and the lower part of the second hydraulic cylinder 8 are fixed together. When the second hydraulic cylinder 8 extends or retracts, the lower part rotates on the second fixing plate through the second connecting rod, and the upper part rotates on the first fixing plate through the first connecting rod.

[0023] A support rod 9 is fixedly installed on the side wall of the discharge pipe 3. The other end of the support rod 9 is fixedly installed together with one of the support plates 5. The support rod 9 plays a supporting and fixing role for the discharge pipe 3.

[0024] In this embodiment, the first hydraulic cylinder 6 and the second hydraulic cylinder 8 are both commercially available conventional devices known to those skilled in the art. In this patent, we are simply using them without making any improvements to their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here.

[0025] In use, the filling device for vibratory crushing stone pile construction involves placing stones into the storage hopper 2, moving the device to the pile hole, aligning the discharge pipe 3 with the hole, and opening the control valve 10. The stones in the storage hopper 2 are then discharged into the pile hole through the discharge pipe 3. If a blockage occurs in the discharge pipe 3, preventing stones from being discharged, the operator activates the second hydraulic cylinder 8. The second hydraulic cylinder 8 retracts, tilting the storage hopper 2 and causing the discharge pipe to open. The material pipe 3 is tilted upwards, causing the stones gathered at the discharge pipe 3 to roll to an area away from the discharge pipe 3, so that they no longer gather at the discharge pipe 3. Then, the first hydraulic cylinder 6 is activated, and the first hydraulic cylinder 6 retracts, driving the baffle 7 to move away from the unblocking area 4 of the discharge pipe 3. After the unblocking area 4 is no longer blocked, the stones gathered in the discharge pipe 3 are discharged from the unblocking area 4 to the outside. After the workers remove the remaining stones in the discharge pipe 3, the first hydraulic cylinder 6 is activated again to extend, driving the baffle 7 to move into the unblocking area 4.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
