Description

Technical Field

[0001] This invention relates to the field of reservoir excavation construction technology, specifically to an excavation mechanism for constructing flood-receiving reservoirs. Background Technology

[0002] Coastal tidal flat flood control reservoirs are a special type of flood control project, mainly distributed along my country's coastal areas. These reservoirs are built to divert floodwaters during the flood season, alleviating flood control pressure on downstream cities. Simultaneously, these reservoirs also serve multiple functions, including regulating water levels, providing irrigation water, and improving the ecological environment. The construction of these flood control reservoirs requires extensive excavation equipment.

[0003] The aforementioned device lacks a structure that allows for switching of the front teeth of the excavating bucket and adjustment of the angles on both sides of the excavating bucket. This makes it difficult for existing excavators used for flood control reservoir construction to switch between different buckets depending on the complex terrain. The switching process is too complicated. Furthermore, when excavating flood control reservoirs, the slope of the reservoir side is relatively steep, and the slope is often excavated first and then repaired. Because the pit wall is relatively straight after excavation by the excavator bucket, subsequent slope repair is difficult and inconvenient to use. Based on the shortcomings of existing technology, this invention designs an excavation mechanism for flood control reservoir construction. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This excavation mechanism for flood-receiving reservoir construction involves rotating the handle counterclockwise, which in turn drives a gear through an axle. The counterclockwise rotating gear, through a meshing single-sided toothed groove, causes an adjusting plate to move upward under the limitation of a limiting groove and a limiting post. At this time, the upward-moving adjusting plate causes the first hinge joint to move upward as well, pushing the push arm connected to the first hinge joint upward. During the upward movement of the push arm, it generates a certain rotation angle through the second hinge joint and itself, pushing the expansion arc plate outward. The outward-pushed expansion arc plate also pushes the adjustable plate to rotate at a certain angle until the adjustable plate reaches the required unfolding angle. This device facilitates the unfolding of the adjustable plate, enabling excavation of slopes at different angles.

[0018] 2. This excavation mechanism for flood-receiving reservoir construction releases the locking mechanism by lifting the locking pin upwards and pulling it out of the lock hole. Then, by gripping the handle and rotating it, the rotating arm is driven to rotate. The rotating arm drives the internal components of the extension mechanism to unfold the adjustable plate. When the adjustable plate reaches the desired unfolding angle, the locking pin is released. The compressed and deformed locking spring rebounds after being released from force, pushing the locking pin to reset and re-insert into the corresponding lock hole to re-lock the rotating arm. This device facilitates locking the angle of the adjustable plate after it is unfolded.

[0019] 3. This excavation mechanism for flood-receiving reservoir construction involves first removing the protective base plate from the bottom of the bucket body. Then, the connecting arm and toothed plate in the receiving groove are bent downwards and rotated under the control of the rotating shaft and the limiting slide until the toothed plate rotates to the front of the bucket teeth. At this point, the toothed plate is pushed backwards and fitted onto the bucket teeth. The backward-pushing toothed plate causes the connecting arm to move backwards as well until the limiting slide on the connecting arm moves to the innermost end of the rotating shaft and the limiting hole aligns with the side hole. At this point, the ejector spring pushes the locking shaft to move outwards and insert into the limiting hole to lock the connecting arm. Because the connecting arm is locked by the locking shaft, the toothed plate cannot move and is stably fitted onto the bucket teeth. Finally, the protective base plate is reinstalled at the bottom of the bucket body to protect the receiving groove and the bottom of the bucket body. This device facilitates the fitting of the toothed plate onto the bucket teeth for different excavation operations. Attached Figure Description

[0032] Please see Figure 6-8The expansion mechanism 5 includes a side groove 501, a rotating groove 502, an adjustable plate 503, and an expansion arc plate 504.

[0033] By setting a rotating groove 502 and an adjustable plate 503, the adjustable plate 503 can be rotated to allow digging operations at any angle. By setting an extension arc plate 504, the gap between the adjustable plate 503 and the bucket body 1 can be filled after the adjustable plate 503 is rotated and unfolded. By setting a first hinge joint 508, a push arm 509 and a second hinge joint 510, the adjustable plate 503 and the extension arc plate 504 can be pushed to unfold and adjust when the adjusting plate 506 moves up and down. By setting a single-sided toothed groove 512, axle 513 and gear 514, the up and down movement of the adjusting plate 506 can be controlled.

[0034] Please see Figure 3-5The tooth-wrapping mechanism 3 includes a long groove 301, a receiving groove 302, a protective base plate 303, a connecting arm 304, a tooth-wrapping plate 305, a limiting hole 306, a rotating shaft 307, a limiting slide groove 308, a side hole 309, a pull groove 310, a locking shaft 311, an ejection spring 312, and a pull arm 313. The long groove 301 is formed at both ends of the bottom of the bucket body 1, the receiving groove 302 is formed at the bottom of the bucket body 1, the protective base plate 303 is fixedly connected to the bottom of the bucket body 1, two connecting arms 304 are movably connected to the inside of the long grooves 301 on both sides, the tooth-wrapping plate 305 is fixedly connected to the front end of the two connecting arms 304, and the limiting hole 306 is formed through the connecting arm 304. On the connecting arm 304, the rotating shaft 307 is fixedly connected to the outside of the connecting arm 304, the limiting slide groove 308 is opened on the side wall of the long groove 301, the side hole 309 is opened on the side wall of the long groove 301, the pull groove 310 is opened through the side hole 309, the locking shaft 311 is slidably connected to the inside of the side hole 309, the ejection spring 312 is set inside the side hole 309, the pull arm 313 is rotatably connected to the locking shaft 311, the toothed plate 305 is set inside the receiving groove 302, the rotating shaft 307 is slidably connected to the inside of the limiting slide groove 308, the locking shaft 311 is slidably inserted into the inside of the limiting hole 306, and the pull arm 313 is movably connected to the inside of the pull groove 310.

[0035] By setting 305, after it is sleeved on the bucket tooth 101, different digging operations can be performed using the bucket body 1. By setting locking shaft 311, after the connecting arm 304 and the tooth plate 305 are unfolded and the tooth plate 305 is sleeved on the bucket tooth 101, locking shaft 311 can be inserted into the limiting hole 306 opened on the connecting arm 304, thereby locking the connecting arm 304 and the tooth plate 305, preventing the connecting arm 304 from moving in the long groove 301 and affecting the stability of the tooth plate 305 sleeved on the bucket tooth 101. By setting pull arm 313, locking shaft 311 can be pulled backward to pull it out from the limiting hole 306 to release the lock on the connecting arm 304, so that the tooth plate 305 can be retracted into the receiving groove 302.

[0036] Please see Figure 9 The locking mechanism 4 includes a rotating arm 401, a handle 402, a fixed post 403, a locking lock 404, a locking spring 405, and a locking hole 406. The rotating arm 401 is fixedly connected to the axle 513, the handle 402 is fixedly connected to the rotating arm 401, the fixed post 403 is fixedly connected to the rotating arm 401, the locking lock 404 is slidably inserted into the rotating arm 401, the locking spring 405 is movably sleeved on the fixed post 403, the locking hole 406 is opened on the back of the bucket body 1, the locking lock 404 is movably inserted into the locking hole 406, the locking lock 404 is slidably connected to the fixed post 403, the locking spring 405 is fixedly connected between the fixed post 403 and the locking lock 404, the rotating arm 401 is rotatably connected to the back of the bucket body 1, and the locking lock 404 is movably inserted into the bucket body 1.

[0037] By setting a rotating arm 401, the adjustable plate 503 is unfolded by driving the internal components of the extension mechanism 5. By setting a locking lock 404, the angle maintained after the adjustable plate 503 is unfolded is locked. By setting a locking spring 405, when the locking lock 404 is released, the locking spring 405 can quickly rebound to push the locking lock 404 to reset and re-insert into the lock hole 406 to re-lock the rotating arm 401 and the extension mechanism 5.

[0038] Working principle: When an excavating mechanism for flood-receiving reservoir construction is used, in the initial state, the bucket teeth 101 are first set at the front end of the bucket body 1, and the mounting bracket 2 is set at the top of the bucket body 1 to facilitate the connection of the bucket body 1 with mechanical equipment for excavation operations. At the bottom of the bucket body 1, a connecting arm 304 and a tooth-covering plate 305 are installed in the long slot 301 and the receiving slot 302. The tooth-covering plate 305 is sleeved on the bucket teeth 101 at the front end of the bucket body 1 to cover the bucket teeth 101 and cope with different excavation operations. A locking shaft 311 is inserted into the side hole 309 at the bottom of the bucket body 1, and a push-out spring 312 is provided between the side hole 309 and the locking shaft 311. The locking shaft 311 is also inserted into the connecting arm 304. The limiting hole 306 on the 04 is used to lock the tooth plate 305 that is sleeved on the bucket tooth 101 after unfolding, so as to prevent it from falling off during the digging process. Adjustable plates 503 are rotatably connected to the rotating grooves 502 on both sides of the bucket body 1. The extension arc plate 504 fixedly connected to the adjustable plate 503 is stored in the side grooves 501 on both sides of the bucket body 1, so as to unfold the two adjustable plates 503 to the sides and adjust the slope angle of the bucket body 1 after digging. At the same time, the rotating arm 401 rotatably connected to the back of the bucket body 1 is connected to the extension mechanism 5, which can effectively control the opening and closing angle of the two adjustable plates 503. The locking 404 inserted into the rotating arm 401 can lock the adjustable plate 503 after the angle is adjusted.

[0039] When the adjustable plate 503 needs to be unfolded to allow for excavation of slopes at different angles, first, hold the handle 402 and rotate it counterclockwise so that the gear 514 is driven to rotate through the axle 513. The counterclockwise rotating gear 514 drives the adjusting plate 506 to move upward under the limitation of the limiting groove 507 and the limiting post 505 through the single-sided toothed slide groove 512 that meshes with it. At this time, the upward moving adjusting plate 506 drives the first hinge joint 508 to move upward as well, and pushes the push arm 509 connected to the first hinge joint 508 upward. At this time, the push arm 509, which is pushed upward, generates a certain rotation angle through the second hinge joint 510 and itself during the upward movement, pushing the expansion arc plate 504 outward. The expansion arc plate 504 pushed outward also pushes the adjustable plate 503 to rotate at a certain angle until the adjustable plate 503 reaches the required unfolding angle. This device facilitates the unfolding of the adjustable plate 503 to allow for excavation of slopes at different angles.

[0040] When it is necessary to lock the angle of the adjustable plate 503 after it is unfolded, first lift the latch 404 upwards to pull it out of the lock hole 406 to release the lock on the rotating arm 401. Then, hold the handle 402 and rotate it to drive the rotating arm 401 to rotate. The rotating arm 401 drives the internal components of the extension mechanism 5 to unfold the adjustable plate 503. When the adjustable plate 503 is unfolded to the required angle, release the latch 404. The locking spring 405, which was compressed and deformed, rebounds after being no longer under force, pushing the latch 404 to reset and re-insert into the corresponding lock hole 406 to re-lock the rotating arm 401. This device facilitates locking the angle of the adjustable plate 503 after it is unfolded.

[0041] When the toothed plate 305 needs to be fitted onto the bucket teeth 101 for different digging operations, first remove the protective bottom plate 303 at the bottom of the bucket body 1. Then, the connecting arm 304 and the toothed plate 305 in the receiving groove 302 are bent downwards and rotated under the limit of the rotating shaft 307 and the limiting slide groove 308 until the toothed plate 305 rotates to the front of the bucket teeth 101. At this time, the toothed plate 305 is pushed backwards to fit onto the bucket teeth 101. The backward push of the toothed plate 305 causes the connecting arm 304 to move backwards as well until the limiting slide groove 308 on the connecting arm 304 is reached. Move the shaft to the innermost end of the rotating shaft 307 and align the limiting hole 306 with the side hole 309. At this time, the ejector spring 312 pushes the locking shaft 311 to move outward and insert into the limiting hole 306 to lock the connecting arm 304. Because the connecting arm 304 is locked by the locking shaft 311, the tooth plate 305 cannot move and is stably sleeved on the bucket tooth 101. Finally, reinstall the protective bottom plate 303 at the bottom of the bucket body 1 to protect the receiving groove 302 and the bottom of the bucket body 1. This device makes it easy to sleeve the tooth plate 305 on the bucket tooth 101 for different digging operations.
