[0025] Example 1

[0026] like Figure 1-Figure 5 As shown, a ballast-removing bucket conveyor proposed in this embodiment includes a vehicle body, a material shoveling and turning mechanism, a lifting mechanism and a conveying mechanism.

[0027] The vehicle body includes an engineering chassis 1 and a cab and power assembly 2 arranged on the engineering chassis 1. The cab and power assembly 2 include a cab and a power assembly for controlling the movement of the engineering chassis 1. The engineering chassis 1 can be selected from, but not limited to, a crawler chassis or a wheeled chassis.

[0028] The material shoveling and turning mechanism includes an arm 13, a bucket 9 pivotally mounted on the arm 13, a booster assembly mounted on the arm 13 that pushes the bucket 9 forward to shovel material into the bucket 9, and a hydraulic motor mounted on the arm 13 that drives the bucket 9 to rotate and tip the material inside. Two symmetrical booster assemblies are provided, each comprising a booster cylinder 15 hingedly mounted on the arm 13, a push ball 151 at the telescopic end of the booster cylinder 15, and an auxiliary cylinder 16 hinged at both ends to the arm 13 and the booster cylinder 15, respectively. The bucket 9 has a support platform 92 at its bottom, which has a ball groove for the push ball 151 to abut. When the booster cylinder 15 extends and the auxiliary cylinder 16 contracts, the push ball 151 can be driven to rotate obliquely upward. The push ball 151 applies force at the ball groove of the push platform 92 to push the bucket 9 upward, thereby assisting in moving the bucket 9 out of the rock pile.

[0029] Two material guide plate portions 91 are symmetrically arranged inside the bucket 9, and the distance between the two material guide plate portions 91 gradually decreases from the inside of the bucket 9 to the opening of the bucket 9. When the bucket 9 flips the material onto the conveying mechanism, the material can be guided by the two material guide plate portions 91 and effectively flipped onto the conveying mechanism, and is not easy to scatter from both sides of the conveying mechanism.

[0030] A lifting mechanism is provided on the engineering chassis 1 and is used to lift the arm 13. The lifting mechanism includes a mounting base 10 provided on the engineering chassis 1, an arm 11 rotatably mounted on the mounting base 10, a first articulated rod 111 and a third articulated rod 141 provided on the arm 11, a second articulated rod 131 provided on the arm 13, a first lifting cylinder 12 having its ends hinged to the engineering chassis 1 and the first articulated rod 111, respectively, and a second lifting cylinder 14 having its ends hinged to the second articulated rod 131 and the third articulated rod 141, respectively. The first lifting cylinder 12 can raise or lower the arm 11, while the second lifting cylinder 14 can raise or lower the arm 13, achieving two-stage lifting and lowering adjustment.

[0031] The conveying mechanism includes a support assembly arranged on the engineering chassis 1 and a chain plate conveyor 3 arranged on the support assembly. The chain plate conveyor 3 can convey the material to the rear until the material falls into the dump truck cargo box.

[0032] This embodiment can perform continuous operations without turning around, thereby improving work efficiency and material transfer volume, with low operating costs. It also has an engineering chassis 1 with strong passability, thereby improving the success rate of escape and rescue. When clearing rock pile materials, the driver controls this ballast removal bucket conveyor in the cab and can operate safely. First, the bucket 9 is placed flat in front of the rock pile material to be cleared, and then the engineering chassis 1 is controlled to move forward to shovel the material into the bucket 9. Then, the movement of the push ball 151 is achieved through the action of the booster cylinder 15 and the auxiliary oil cylinder 16. The push ball 151 lifts the bucket 9 out of the rock pile material by pushing the support platform 92, and the material effectively enters the bucket 9. Then, the arm 13 is lifted upward to the top of the chain plate conveyor 3 through the lifting mechanism, and the hydraulic motor is started to drive the bucket 9 to rotate, and the material in the bucket 9 is dumped onto the chain plate conveyor 3. The chain plate conveyor 3 is used to transport the material to the dump truck cargo box. The ballast dump conveyor only needs to move forward and scoop up the material and transfer it backwards without having to move backwards during the cleaning process.

[0033] Example 2

[0034] like Figure 1-Figure 5 As shown, the present embodiment proposes a ballast removal bucket conveyor. Compared with the first embodiment, in this embodiment, the support assembly is symmetrically arranged in two groups about the engineering chassis 1, including a guide rail horizontally arranged on the engineering chassis 1, a first support column 4, a first roller rotatably arranged at the bottom of the first support column 4 and rolling on the guide rail, a second support column 5, and a second roller rotatably arranged at the bottom of the second support column 5 and rolling on the guide rail. A sliding cylinder 17 is connected between the mounting base 10 and the second support column 5. The sliding cylinder 17 can drive the second support column 5 to move, specifically by the rolling of the first and second rollers on the guide rail to achieve movement of the support column.

[0035] Side panels are installed on both sides of the chain plate conveyor 3 along its width. These panels prevent material from spilling out during conveyance. The side panels are equipped with a first mounting shaft connected to the first support column 4 and a second mounting shaft connected to the second support column 5. The support columns support the side panels and the entire chain plate conveyor 3 via the mounting shafts.

[0036] like Figure 1 and Figure 2As shown, the first support column 4 includes a first lower cylinder, a first upper cylinder vertically slidingly arranged on the first lower cylinder, and a first hydraulic cylinder arranged in the first lower cylinder and driving the first upper cylinder to rise and fall, and the first upper cylinder is rotatably connected to the first mounting shaft. The second support column 5 includes a second lower cylinder, a second upper cylinder vertically slidingly arranged on the second lower cylinder, and a second hydraulic cylinder arranged in the second lower cylinder and driving the second upper cylinder to rise and fall, and the second mounting shaft is rotatably connected to the second upper cylinder. The first hydraulic cylinder and the second hydraulic cylinder can be extended and retracted separately to control the height of the first support column 4 or the second support column 5, and then drive the entire chain plate conveyor 3 to rotate through the corresponding mounting shaft to adjust the conveying direction of the chain plate conveyor 3. Because the rollers roll on the guide rails, the above-mentioned direction adjustment process can be effectively implemented.

[0037] The side panels are provided with grooves 301 for the bucket 9 to engage. When the bucket 9 drops material onto the chain-slat conveyor 3, it engages in grooves 301, bringing the opening of the bucket 9 closer to the chain-slat conveyor 3. This reduces the chance of material splashing and spilling onto the outside of the chain-slat conveyor 3. To further ensure accurate rearward conveyance of material, the side panels are provided with limit plates 8, which gradually tilt upward in the direction of conveyance of the chain-slat conveyor 3. When the bucket 9 drops material behind the limit plates 8, they hold the material in place, preventing it from falling out the front.

[0038] like Figure 1 、 Figure 2 and Figure 5 As shown, a connecting frame 6 is provided at the end of the side panel away from the bucket 9, on which a roller 7 is rotatably mounted. When the sliding cylinder 17 is extended, the roller 7 moves backward and rolls backward on the dump truck's cargo bed, facilitating efficient material transport to the dump truck's cargo bed via the chain plate conveyor 3. When the ballast removal and dump bucket conveyor is not in use, the sliding cylinder 17 is retracted, and the chain plate conveyor 3 moves forward, reducing the overall space requirements of the ballast removal and dump bucket conveyor.

[0039] The operating method of the above-mentioned ballast removal bucket conveyor comprises the following steps:

[0040] S1. The driver controls the ballast removal bucket conveyor in the cab and power assembly 2, and drives the vehicle body to the location to be cleaned;

[0041] S2. The second support column 5 is driven backward by the sliding cylinder 17, so that the chain plate conveyor 3 moves backward, and the roller 7 rolls on the dump truck cargo bucket until it rolls to a position close to the front of the dump truck;

[0042] S3, level the bucket 9, move the vehicle body forward, and cut the bucket 9 into the rock pile;

[0043] S4, pushing the bucket 9 forward by the booster push assembly to shovel the rock pile material into the bucket 9;

[0044] S5, the lifting mechanism lifts the arm 13 and moves the bucket 9 to the top of the chain plate conveyor 3;

[0045] S6, driving the bucket 9 to rotate by the hydraulic motor, and dropping the material in the bucket 9 onto the chain plate conveyor 3;

[0046] S7. The chain-slat conveyor 3 conveys the material backward into the dump truck's cargo hopper. As the material continues to be unloaded, the dump truck can adaptively move forward, so that the material gradually accumulates from the front to the back of the dump truck's cargo hopper, ensuring the material loading capacity. By utilizing the tilting material transfer and the chain-slat conveyor 3, the height and width of the bucket 9 movement can be effectively reduced, while meeting the height and width requirements of the dump truck loading.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
