[0027] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments. Example 1:

[0028] A type of drum-type earthmoving excavator, such as Figure 1-5 As shown, it includes: a frame chassis 10, a first digging mechanism, a second digging mechanism, a conveying mechanism, and a control assembly; the frame chassis 10 is equipped with a self-propelled mechanism 11; the first digging mechanism includes two first connecting arms 12, a first motor, and a first digging roller 14, the two first connecting arms 12 being rotatably connected to one end of the self-propelled mechanism, the first digging roller 14 being rotatably connected to the first connecting arms 12, the first motor being disposed within the first connecting arms 12 and the output shaft of the first motor being connected to the first digging roller 14; the second digging mechanism includes a second connecting arm 22, a second motor, and a second digging roller 23, the second connecting arm... The first digging roller 14 is rotatably connected to the frame chassis 10, and the second digging roller 23 is rotatably connected to the second connecting arm 22. The second motor is located inside the second connecting arm 22 and its output shaft is connected to the second digging roller 23. The conveying mechanism is located at the bottom of the frame chassis 10 and is located on one side of the first digging roller 14. The control components include a first hydraulic cylinder 15 and a second hydraulic cylinder 25, which are rotatably connected to the frame chassis 10, and the extension and retraction ends of the first hydraulic cylinder 15 and the second hydraulic cylinder 25 are rotatably connected to the first connecting arm 12 and the second connecting arm 22, respectively.

[0029] By adopting the above structure, the angle and height of the first digging mechanism and the second digging mechanism can be adjusted by extending and retracting the first hydraulic cylinder 15 and the second hydraulic cylinder 25, thereby enhancing the applicability of the device under different terrain conditions, especially sloping terrain. Furthermore, the first digging roller 14 rotates from bottom to top, rotating the cut soil along the first spiral blade 142 and throwing it onto the conveying mechanism, thus solving the common problems of soil accumulation and blockage in traditional equipment.

[0030] The design, which combines the first excavating roller 14, the second excavating roller 23, and the conveying mechanism, expands the working area for excavating the foundation pit and allows the cut soil to be transported smoothly to the conveying mechanism.

[0031] By setting a first connecting arm 12 and a second connecting arm 22 to support the digging rollers, the two digging rollers can simultaneously perform digging operations on the pit sidewall and the pit sidewall on the side of the device as the device moves forward.

[0032] The first motor and the second motor control the operation of the first digging roller 14 and the second digging roller 23 respectively. The first digging roller 14 and the second digging roller 23 rotate in opposite directions, so that the soil cut by the first digging roller 14 and the second digging roller 23 falls onto the conveyor belt 20.

[0033] Specifically, the self-propelled mechanism 11 can be either tracked or wheeled.

[0034] In embodiments of this utility model, such as Figure 1-5 As shown, the conveying mechanism includes: two connecting parts 16, a base 17, a drive roller 18, a driven roller 19, a conveyor belt 20, and a third motor; the two connecting parts 16 are respectively located on both sides of the front end of the frame chassis 10; the base 17 is equipped with tires at its bottom, and the base 17 is connected to the two connecting parts 16, and the base 17 is located at the bottom of the frame chassis 10; the drive roller 18 is located on one side of the base 17; the driven roller 19 is located on the other side of the base 17; the conveyor belt 20 is wound around the outside of both the drive roller 18 and the driven roller 19; the third motor is fixed on the base 17 and is connected to the drive roller 18; wherein, the conveyor belt 20 is located on one side of the first digging roller 14.

[0035] The third motor drives the active roller 18 to rotate, thereby causing the conveyor belt 20 to be driven by the cooperation of the active roller 18 and the driven roller 19, which in turn moves the soil falling on the conveyor belt 20 to the designated position, thus preventing the soil from piling up in one place.

[0036] Specifically, when the device moves, the base 17 is used in conjunction with the tires via the connector 16 to achieve the purpose of following the movement of the device.

[0037] In embodiments of this utility model, such as Figure 1-5 As shown, it also includes: a first rotating seat 13 and a second rotating seat 24; the first rotating seat 13 is disposed on the frame chassis 10, and the first hydraulic cylinder 15 is mounted on the first rotating seat 13; the second rotating seat 24 is disposed on the frame chassis 10, and the second hydraulic cylinder 25 is mounted on the second rotating seat 24.

[0038] The first rotating seat 13 and the second rotating seat 24 support the first hydraulic cylinder 15 and the second hydraulic cylinder 25 respectively. The angle and height of the second digging roller 23 can be adjusted by extending and retracting the first hydraulic cylinder 15 and the second hydraulic cylinder 25, so that the workers can make adjustments according to actual needs.

[0039] In embodiments of this utility model, such as Figure 1-5As shown, the first digging roller 14 includes: a first rotating shaft 141, a first spiral blade 142 and a first shovel tooth 143; the first rotating shaft 141 is rotatably connected to the first connecting arm 12; the first spiral blade 142 is disposed on the outer side of the first rotating shaft 141; the first shovel tooth 143 is disposed on the side wall of the first spiral blade 142.

[0040] The first rotating shaft 141 drives the first spiral blade 142 to rotate, and the first shovel teeth 143 cut or excavate the soil. The cut soil is transported along the spiral direction and falls onto the conveyor belt 20, thereby ensuring the continuous transport of soil.

[0041] In embodiments of this utility model, such as Figure 1-5 As shown, the second digging roller 23 includes: a second rotating shaft 231, a second spiral blade 232, and a second shovel tooth 233; the second rotating shaft 231 is rotatably connected to the second connecting arm 22; the second spiral blade 232 is disposed on the outer side of the second rotating shaft 231; and the second shovel tooth 233 is disposed on the side wall of the second spiral blade 232.

[0042] The second rotating shaft 231 drives the second spiral blade 232 to rotate, and the second shovel teeth 233 cut or excavate the soil. The cut soil is then transported along the spiral direction and falls onto the conveyor belt 20.

[0043] Specifically, by using the first digging roller 14 and the second digging roller 23 in combination, the working area can be effectively expanded when cutting or excavating the slope.

[0044] In the embodiments of this utility model, the rotation directions of the first rotating shaft 141 and the second rotating shaft 231 are opposite, the directions of the first helical blade 141 and the second helical blade 232 are opposite, and the directions of the first shovel tooth 143 and the second shovel tooth 233 are opposite.

[0045] By rotating the first shaft 141 and the second shaft 231 in opposite directions, with the first helical blade 142 and the second helical blade 232 in opposite directions, and with the first shovel tooth 143 and the second shovel tooth 233 in opposite directions, the excavated soil by the first shovel tooth 143 and the second shovel tooth 233 can fall onto the conveyor belt 20 through the first helical blade 142 and the second helical blade 232 respectively, so as to transport it.

[0046] In embodiments of this utility model, such as Figure 1-5As shown, it also includes: a transport platform 26, a first roller shaft 27, a second roller shaft, a transport belt 28, and a fourth motor; the bottom of the transport platform 26 is equipped with casters, and the transport platform 26 is connected to the base 17 via a mounting component 21; the first roller shaft 27 is located on one side of the transport platform 26; the second roller shaft is located on the other side of the transport platform 26; the transport belt 28 is simultaneously wound around the outside of the first roller shaft 27 and the second roller shaft, one end of the transport belt 28 is located below the conveyor belt 20, and the other end of the transport belt 28 is opposite to the earthmoving vehicle; the fourth motor is fixed on one side of the transport platform 26, and the fourth motor is connected to the first roller shaft 27.

[0047] With the operation of the fourth motor, and the cooperation of the first roller 27 and the second roller, the conveyor belt 28 transports the soil conveyed by the conveyor belt 20 into the conveyor belt 28, and the conveyor belt 28 transports the soil to the soil transport vehicle.

[0048] Specifically, the number of transport platforms 26 can be increased according to the distance between the earthmoving vehicle and the chassis 10, so that the transport platforms 26 can smoothly transport the earthmoving material conveyed by the conveyor belt 20 to the earthmoving vehicle.

[0049] Specifically, the fourth motor and the third motor are both installed inside the protective housing, which is fixed to the sides of the base 17 and the transport platform 26, respectively.

[0050] Specifically, in the prior art, when an excavator is working, the earthmoving trucks used to transport the excavated soil need to travel into the foundation pit. Sometimes, the temporary ramps have a large slope and a small bearing capacity, making it easy for the earthmoving trucks to get stuck on the slope and unable to move. By using multiple transport platforms 26 and conveyor belts 20 in combination as described in this embodiment, the soil excavated by the excavator can be smoothly transported to the earthmoving trucks. This allows the earthmoving trucks to transport the soil without having to travel into the foundation pit, and this structure also increases the transport capacity.

[0051] In an embodiment of this utility model, the transport platform 26 is tilted at a predetermined angle, thereby transporting the excavated soil onto the excavated soil transport vehicle.

[0052] Implementation Process: The angle and height of the excavating rollers are adjusted by hydraulic cylinders, enhancing the device's applicability to various terrain conditions. The first excavating roller rotates from bottom to top, rotating the cut soil along the first helical blades and throwing it onto the conveying mechanism, thus solving the common problems of soil accumulation and clogging in traditional equipment. The combined use of two excavating rollers and the conveying mechanism expands the working area for excavating the foundation pit and allows the cut soil to be smoothly transported to the conveying mechanism. By setting the rotation direction of the two excavating rollers to be opposite to the direction of the shovel teeth, the soil excavated by both rollers is ensured to fall onto the conveying mechanism. A first connecting arm and a second connecting arm support the excavating rollers, allowing both rollers to simultaneously excavate the foundation pit sidewalls along the device's forward movement and those on the device's side when the device is moving close to the pit sidewall.
