Description

Technical Field

[0001] The utility model belongs to the technical field of dump trucks, and specifically relates to a silt cleaning device for a dump truck carriage. Background Technique

[0002] A dump truck refers to a vehicle that can unload goods by itself through hydraulic or mechanical lifting. It is also called a tipping truck. It consists of components such as an automobile chassis, a hydraulic lifting mechanism, a cargo compartment, and a power take-off device. The cargo compartment of the dump truck is divided into two types: rearward tipping and side tipping. By controlling the movement of the piston rod through the control system, rearward tipping is more common. The piston rod is pushed to tip the cargo compartment, and a few are double-direction tipping. Dump trucks often cooperate with construction machinery such as excavators, loaders, and belt conveyors in civil engineering to form a loading, transporting, and unloading production line for the loading, transporting, and unloading of earthwork, sand and gravel, and bulk materials.

[0003] At present, when the cargo compartment of a dump truck in the prior art is actually used, although the inner wall is relatively smooth, due to the wet condition of the transported soil, it adheres to the inner wall of the cargo compartment, resulting in the problem of difficult unloading. Content of the Utility Model

[0004] The purpose of the utility model is to provide a silt cleaning device for a dump truck carriage to solve at least one of the problems and defects mentioned in the above background technique.

[0005] Provide a silt cleaning device for a dump truck carriage, including a dump truck carriage main body. Rack bars are arranged on both sides of the upper part of the dump truck carriage main body. First fixing seats and second fixing seats are also arranged on both sides of the upper part of the dump truck carriage main body. Guide rods are arranged between the first fixing seats and the second fixing seats. Movable seats are slidably connected to the guide rods. Both of the movable seats are fixedly connected with movable plates. A servo motor is arranged on one side of the upper part of the movable plate. The output shaft of the servo motor penetrates through the movable plate and is fixedly connected with a connecting shaft. Driving gears are fixedly connected to the connecting shafts. Rack bars are meshed and connected above the driving gears. A silt cleaning scraper is arranged below the movable plate.

[0006] Furthermore, the silt cleaning scraper is slidably connected inside the dump truck carriage main body. The bottom of the silt cleaning scraper contacts the inner wall of the dump truck carriage main body. The silt cleaning scraper and the dump truck carriage main body are fixed and guided through a sliding connection. The sliding connection can ensure that the scraper moves smoothly along the surface of the inner wall of the carriage without deviating from the path, and can effectively remove silt or soil. The bottom of the silt cleaning scraper directly contacts the inner wall of the carriage. Since the scraper is close to the inner wall of the carriage, when it slides under the drive of the servo motor, it can completely scrape off the soil or silt adhering to the inner wall, avoiding the adhesion of wet soil or silt residues on the carriage.

[0007] Further, receiving grooves are symmetrically arranged on both sides of the upper part of the driving gear, and the connecting shaft is rotatably connected in the receiving grooves. The arrangement of the receiving grooves provides space to accommodate the connecting shaft, thereby making the structure of the connecting shaft and the driving gear more compact and stable. By fixing the connecting shaft in the receiving grooves, the movement of the driving gear can be ensured to be stable, avoiding transmission errors caused by vibration or loosening. The connecting shaft is rotatably connected through the receiving grooves, and the connecting shaft can rotate freely in the receiving grooves, enabling it to operate smoothly under the drive of the servo motor, driving the rack to move, and improving the transmission stability and working life of the entire device.

[0008] Further, the receiving grooves are located inside the rack, and the receiving grooves are located above the rack. The rack being located inside the receiving grooves can ensure that its meshing with the driving gear always remains in an accurate position. Since the receiving grooves limit the lateral movement or deformation of the rack, the meshing between the gear and the rack is smoother, and the transmission error is reduced.

[0009] Further, the movable plate is a U-shaped movable plate. The rack being located inside the receiving grooves can ensure that its meshing with the driving gear always remains in an accurate position. Since the receiving grooves limit the lateral movement or deformation of the rack, the meshing between the gear and the rack is smoother, and the transmission error is reduced.

[0010] Further, an installation through hole is provided on the front surface of the movable seat, and a ball bushing is fixedly installed inside the installation through hole. The ball bushing is sleeved outside the guide rod. Start the servo motor, drive the connecting shaft connected to its output shaft to drive the driving gear to rotate, cooperate with the rack, so that the movable plate drives the dredging scraper to move, scrape the silt, and at the same time, the movable seat connected to the movable plate moves along the outside of the guide rod, and the ball bushing can avoid friction between the movable seat and the guide rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By starting the servo motor, driving the connecting shaft connected to its output shaft to drive the driving gear to rotate, and cooperating with the rack, the movement of the movable plate is controlled. The movement of the movable plate drives the dredging scraper to move, and the dredging scraper reciprocates to clean the main body of the dump truck carriage, thereby being able to scrape the silt inside the main body of the dump truck carriage, facilitating unloading, and being able to avoid the situation that when the dump truck carriage is actually used, the transported soil is prone to adhere to the inner wall of the dump truck carriage after getting wet, resulting in the phenomenon of difficult unloading.

In addition, the accompanying drawings and the following descriptions are provided for those skilled in the art to fully understand the present application and are not intended to limit the subject matter recited in the claims.

[0022] Please refer to Figures 1-4 In an embodiment of the present utility model, a silt cleaning device for a dump truck carriage includes a dump truck carriage main body 2. On both sides of the upper part of the dump truck carriage main body 2, racks 6 are provided. On both sides of the upper part of the dump truck carriage main body 2, a first fixed seat 3 and a second fixed seat 14 are also provided. A guide rod 1 is provided between the first fixed seat 3 and the second fixed seat 14. A movable seat 11 is slidably connected to the guide rod 1. Both movable seats 11 are fixedly connected to a movable plate 4. On one side of the upper part of the movable plate 4, a servo motor 10 is provided. The output shaft of the servo motor 10 penetrates through the movable plate 4 and is fixedly connected to a connecting shaft 13. A driving gear 12 is fixedly connected to the connecting shaft 13. Above the driving gear 12, a rack 6 is meshed. Below the movable plate 4, a silt cleaning scraper 5 is provided. Racks 6 are provided on both sides of the dump truck carriage main body 2. The racks 6 cooperate with fixed components such as the guide rod 1 and the movable seat 11 to form a guiding and supporting structure for the movable plate 4. The guide rod 1 is installed on the dump truck carriage main body 2 through the first fixed seat 3 and the second fixed seat 14, ensuring that the movable plate 4 can slide along a predetermined path. The servo motor 10 is connected to the connecting shaft 13 through the output shaft. The connecting shaft 13 drives the driving gear 12 fixed thereon to rotate. The driving gear 12 meshes with the rack 6. The rotation of the driving gear 12 causes the rack 6 to produce a linear displacement, thereby driving the movable plate 4 to slide along the guide rod 1, and then driving the silt cleaning scraper 5 to perform a reciprocating motion on the inner wall surface of the dump truck carriage main body 2. By the movement of the silt cleaning scraper 5, the silt or wet soil attached to the inner wall of the carriage can be scraped off, realizing the automatic silt cleaning function of the carriage. Through the reciprocating motion of the silt cleaning scraper 5, the soil attached to the inner wall of the carriage can be effectively removed, preventing the problem that the wet soil adheres to the inner wall of the carriage during transportation, resulting in unsmooth unloading.

[0023] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3, the dredging scraper 5 is slidably connected inside the main body 2 of the dump truck carriage. The bottom of the dredging scraper 5 contacts the inner wall of the main body 2 of the dump truck carriage. The dredging scraper 5 and the main body 2 of the dump truck carriage are fixed and guided through the sliding connection. The sliding connection can ensure that the dredging scraper 5 moves smoothly along the inner wall surface of the main body 2 of the dump truck carriage without deviating from the path, effectively removing silt or mud. The contact between the dredging scraper 5 and the inner wall of the main body 2 of the dump truck carriage, when the dredging scraper 5 slides under the drive of the servo motor 10, can completely scrape off the soil or silt adhering to the inner wall of the main body 2 of the dump truck carriage, which is applicable to the situation where wet soil or silt is more likely to adhere.

[0024] Please refer to Figure 1 、 Figure 2 and Figure 4 , on both sides of the upper part of the driving gear 12, receiving grooves 9 are symmetrically arranged. The connecting shaft 13 is rotatably connected in the receiving grooves 9. The arrangement of the receiving grooves 9 provides space to accommodate the connecting shaft 13, thereby making the structure of the connecting shaft 13 and the driving gear 12 more compact and stable. By fixing the connecting shaft 13 in the receiving grooves 9, the movement of the driving gear 12 can be ensured to be stable, avoiding transmission errors caused by vibration or loosening. The connecting shaft 13 is rotatably connected through the receiving grooves 9, which means that the connecting shaft can rotate freely in the receiving grooves 9. The rotation of the driving gear 12 provides freedom, enabling it to operate smoothly under the drive of the servo motor 10 and driving the rack 6 to move. The rotational connection ensures that the driving gear 12 can operate smoothly, improving the transmission stability and working life of the entire device.

[0025] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 , the rack 6 is located inside the receiving groove 9 and above the guide rod 1. The rack 6 being located inside the receiving groove 9 can ensure that its meshing with the driving gear 12 always remains in an accurate position. Since the receiving groove 9 restricts the lateral movement or deformation of the rack 6, the meshing between the driving gear 12 and the rack 6 is smoother and the transmission error is reduced.

[0026] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3, the movable plate 4 is a U-shaped movable plate. Compared with the flat plate structure, the U-shaped structure has stronger bending and anti-deformation capabilities. Due to the additional support added by the "edges" on both sides of the U-shaped structure, the movable plate 4 can better maintain its shape when subjected to external forces (such as the resistance encountered during the dredging process), and is not easily bent or deformed. This improves the durability and stability of the entire device. The U-shaped design increases the materials in the longitudinal and transverse directions, making the movable plate 4 have higher rigidity when subjected to loads, so that it can withstand larger working loads. Especially when the dredging scraper 5 removes silt or mud, the U-shaped movable plate 4 can more stably transmit the driving force.

[0027] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 , an installation through hole 8 is formed on the front surface of the movable seat 11. A ball bushing 7 is fixedly installed inside the installation through hole 8. The ball bushing 7 is arranged outside the guide rod 1. The movable plate 4 is movably connected to the dump truck carriage main body 2 by the movable seat 11 and the guide rod 1. And a ball bushing 7 is arranged between the movable seat 11 and the guide rod 1, which can avoid friction and improve the smoothness of the movable plate 4 driving the dredging scraper 5 to move. Start the servo motor 10, drive the connecting shaft 13 connected to its output shaft to drive the driving gear 12 to rotate, cooperate with the rack 6, so that the movable plate 4 drives the dredging scraper 5 to move and scrape the silt. At the same time, the movable seat 11 connected to the movable plate 4 moves along the outside of the guide rod 1, and the ball bushing 7 can prevent friction between the movable seat 11 and the guide rod 1.
