[0033] Embodiment 1

[0034] 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.

[0035] The vehicle body includes an engineering chassis 1 and a cab and a power assembly 2 arranged on the engineering chassis 1, wherein the cab and the power assembly 2 include a cab and a power assembly for controlling the movement of the engineering chassis 1. The engineering chassis 1 is selected from but not limited to a crawler chassis or a wheeled chassis.

[0036] The material shoveling and turning mechanism includes a small arm 13, a bucket 9 rotatably mounted on the small arm 13, a booster push assembly mounted on the small arm 13 and shoveling materials into the bucket 9 by pushing the bucket 9 forward, and a hydraulic motor mounted on the small arm 13 and driving the bucket 9 to rotate so as to turn over the materials in the bucket 9. Two groups of booster push assemblies are symmetrically arranged, and the booster push assembly includes a booster push oil cylinder 15 hingedly mounted on the small arm 13, a push ball 151 arranged at the telescopic end of the booster push oil cylinder 15, and an auxiliary oil cylinder 16 whose two ends are respectively hinged to the small arm 13 and the booster push oil cylinder 15. The bottom of the bucket 9 has a support platform 92, and the support platform 92 has a ball groove for the push ball 151 to abut. When the booster cylinder 15 is extended and the auxiliary cylinder 16 is contracted, the push ball 151 can be driven to rotate obliquely upward, and 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.

[0037] 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. Therefore, 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.

[0038] The lifting mechanism is arranged on the engineering chassis 1, and is used to lift the small arm 13. The lifting mechanism includes a mounting base 10 arranged on the engineering chassis 1, a large arm 11 rotatably arranged on the mounting base 10, a first hinged rod 111 and a third hinged rod 141 arranged on the large arm 11, a second hinged rod 131 arranged on the small arm 13, a first lifting cylinder 12 whose two ends are respectively hinged to the engineering chassis 1 and the first hinged rod 111, and a second lifting cylinder 14 whose two ends are respectively hinged to the second hinged rod 131 and the third hinged rod 141. The large arm 11 can be lifted or lowered by the first lifting cylinder 12, and the small arm 13 can be lifted or lowered by the second lifting cylinder 14, so as to realize two-stage lifting adjustment.

[0039] 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 cargo box of the dump truck.

[0040] This embodiment can perform continuous operation without turning around, thereby improving work efficiency and material transfer volume, with low cost of use. 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 work safely. First, the bucket 9 is placed flat on the front side 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 push 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, so that the material in the bucket 9 is tipped onto the chain plate conveyor 3, and the chain plate conveyor 3 is used to transport the material to the dump truck cargo bucket. The ballast dump conveyor only needs to move forward and scoop up and transfer the material backwards without moving backwards during the cleaning process.

[0041] Embodiment 2

[0042] like Figure 1-Figure 5 As shown, a ballast removal bucket conveyor proposed in this embodiment, compared with the first embodiment, in this embodiment, two groups of support components are symmetrically arranged 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 seat 10 and the second support column 5. The second support column 5 can be driven to move by the sliding cylinder 17, and the movement of the support column is realized by the rolling of the first roller and the second roller on the guide rail.

[0043] Side plates are provided on both sides of the chain plate conveyor 3 in the width direction, and the side plates can prevent materials from scattering from both sides during the conveying process. The side plates are provided 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 plates and the entire chain plate conveyor 3 through the mounting shafts.

[0044] like Figure 1 and Figure 2As shown, the first support column 4 includes a first lower cylinder, a first upper cylinder vertically slidably 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 slidably 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, so as 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.

[0045] The side plate is provided with a groove 301 for the bucket 9 to be inserted into. When the bucket 9 flips the material onto the chain plate conveyor 3, the bucket 9 is inserted into the groove 301, and the distance between the opening of the bucket 9 and the chain plate conveyor 3 is closer, and the material is less likely to splash when falling, and is less likely to scatter to the outside of the chain plate conveyor 3. In order to further accurately convey the material backward, a limit plate 8 is provided on the side plate, and the limit plate 8 gradually tilts from bottom to top toward the conveying direction of the chain plate conveyor 3. The bucket 9 flips the material to the rear side of the limit plate 8, and the limit plate 8 limits the material to prevent the material from falling from the front end.

[0046] like Figure 1 , Figure 2 and Figure 5 As shown, a connecting frame 6 is provided at one end of the side plate away from the bucket 9, and a roller 7 is rotatably provided on the connecting frame 6. When the sliding cylinder 17 is extended, the roller 7 moves backward and rolls backward on the dump truck bucket, so that the material can be effectively transported to the dump truck bucket through the chain plate conveyor 3. When the ballast removal and dumping bucket conveyor is not in use, the sliding cylinder 17 is retracted, and the chain plate conveyor 3 moves forward, reducing the space size of the entire ballast removal and dumping bucket conveyor.

[0047] The operating method of the above-mentioned ballast removal bucket conveyor comprises the following steps:

[0048] S1, the driver controls the ballast removal bucket conveyor in the cab and power assembly 2, and drives the vehicle body to the position to be cleaned;

[0049] S2, the second support column 5 is driven to move 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;

[0050] S3, level the bucket 9, move the vehicle body forward, and cut the bucket 9 into the rock pile;

[0051] S4, pushing the bucket 9 forward by the booster push assembly to shovel the rock pile material into the bucket 9;

[0052] S5, the lifting mechanism lifts the small arm 13 and moves the bucket 9 to the top of the chain plate conveyor 3;

[0053] S6, driving the bucket 9 to rotate by the hydraulic motor, and flipping the materials in the bucket 9 onto the chain plate conveyor 3;

[0054] S7, the chain plate conveyor 3 conveys the material backward to the dump truck cargo bucket. As the material is continuously unloaded, the dump truck can adaptively move forward so that the material is gradually accumulated from front to back on the dump truck cargo bucket to ensure the material loading amount. By utilizing the tipping material transfer and the chain plate conveyor 3, the height and width of the bucket 9 movement can be effectively reduced, while meeting the requirements of the dump truck loading height and width.

[0055] 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, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
