Description
Technical Field
[0001] The utility model relates to the technical field of coarse-grained soil sorting, in particular to a coarse-grained soil sorting device fixed to the tail of a dump truck. Background Technique
[0002] A dump truck refers to a vehicle that can unload goods automatically by hydraulic or mechanical lifting. In civil engineering, dump trucks often cooperate with construction machinery such as excavators, loaders, and belt conveyors to form a loading, transportation, and unloading production line for the loading, transportation, and unloading of earthwork, sand and gravel, and bulk materials. Since the loading carriage can automatically tilt at a certain angle for unloading, it greatly saves unloading time and labor, shortens the transportation cycle, improves production efficiency, and reduces transportation costs. It is a commonly used special transportation vehicle.
[0003] Coarse-grained soil refers to soil in which the content of soil particles with a particle size of 0.075 - 60 mm is higher than 50% of the total mass of the soil sample, which is roughly equivalent to sandy soil. Gravel soil, sand and gravel, residual slope gravel, and weathered rock debris are collectively referred to as coarse-grained soil, simply called coarse-grained soil; the particle size of coarse-grained soil varies widely, and the characteristics of coarse and fine particles are very different; therefore, directly using the taken coarse-grained soil cannot meet the construction requirements, and the coarse-grained soil needs to be screened and then filled and used according to the standard gradation.
[0004] The existing grading screening work of subgrade fillers is mostly carried out by separating the transportation process from the sorting process, that is, after the used coarse-grained soil is transported to the site by a dump truck and dumped somewhere, it is sorted by a screening device before construction; this screening method has complicated procedures, and it is necessary to pour the coarse-grained soil out of the dump truck and then transfer it to the screening device for screening again, with high construction intensity and low construction efficiency.
[0005] Therefore, in view of the above situation, it is necessary to develop a coarse-grained soil sorting device fixed to the tail of a dump truck to realize the sorting process while the dump truck automatically unloads the coarse-grained soil. Content of the Utility Model
[0006] Aiming at the deficiencies in the prior art, the utility model provides a coarse-grained soil sorting device fixed to the tail of a dump truck, which solves the problems of complicated procedures and low working efficiency in the existing coarse-grained soil screening method.
[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0008] A coarse-grained soil sorting device fixed to the tail of a dump truck, comprising a support base, a sieve box, transverse guide rails, a sieve conveyor mechanism, a driving mechanism and a vibration mechanism; a sieve box is arranged on the support base; two transverse guide rails are arranged on both sides of the sieve box, and a sieve conveyor mechanism is slidably arranged on the two transverse guide rails; a driving mechanism is fixed on the sieve conveyor mechanism, and the driving mechanism drives the sieve conveyor mechanism to rotate; the sieve conveyor mechanism is movably connected to the vibration mechanism, and the vibration mechanism drives the sieve conveyor mechanism to vibrate along the transverse guide rails.
[0009] In this solution, the dump truck dumps the coarse-grained soil onto the sieve conveyor mechanism; under the vibration action of the vibration mechanism, the small-particle soil in the coarse-grained soil on it passes through the sieve conveyor mechanism, and the large-particle soil remains on the screening and conveying mechanism; at the same time, under the drive of the driving mechanism, the large-particle soil remaining on the top of the screening and conveying mechanism is transported to one side of the screening and conveying mechanism, thus realizing the screening work of the coarse-grained soil. This screening method has high working efficiency and can screen the coarse-grained soil during the unloading process, without the need to dump the coarse-grained soil to a certain place and then transfer it to the screening device for screening again, reducing the working intensity.
[0010] Furthermore, the sieve conveyor mechanism includes a sieve conveyor belt arranged on two transmission wheels, and one of the transmission wheels is in transmission connection with the driving mechanism; the two transmission wheels are in transmission connection through a transmission belt; two sliders are respectively arranged on both sides of the two transmission wheels, and the two ends of the two transmission wheels are respectively rotated on the two sliders; the two sliders are respectively slidably arranged on the two transverse guide rails.
[0011] In this solution, the driving mechanism drives the transmission wheel and the sieve conveyor belt arranged on the surface of the transmission wheel to rotate, and the large-particle soil on the sieve conveyor belt is transported out during the rotation; realizing the synchronous screening and transportation of the coarse-grained soil, with high working efficiency.
[0012] Furthermore, the vibration mechanism includes a vibration motor, a crankshaft and a connecting rod; the vibration motor is arranged on the motor base on one side of the sieve box, and the fixed end of the crankshaft is rotatably connected to the bottom of the motor base; the vibration motor is connected to the fixed end of the crankshaft through a belt, the rotating end of the crankshaft is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is connected to the slider.
[0013] In this solution, the vibration motor drives the crankshaft to rotate around its fixed end. During the rotation, the crankshaft pulls the slider to move back and forth along the transverse guide rail through the connecting rod, thereby driving the sieve conveyor belt on the slider to move back and forth to realize the reciprocating vibration effect of the sieve conveyor belt; during the reciprocating vibration, the small-particle soil on the surface of the sieve conveyor belt can quickly be discharged from the pores of the sieve conveyor belt; this design accelerates the screening process of the small-particle soil, preventing the small-particle soil from being screened too slowly and being transported away together with the large-particle soil, thus unable to achieve effective screening.
[0014] Further, the driving mechanism includes a driving motor which is fixedly installed on one of the sliders, and the driving motor is connected to one of the transmission wheels through belt drive.
[0015] In this solution, the driving motor is arranged on the slider. When the slider moves along the transverse guide rail, the driving motor moves synchronously with it, ensuring that the transmission work of the screen conveyor belt during vibration is uninterrupted; a continuous screening process is realized.
[0016] Further, an L-shaped hook is hinged to one side of the screen box connected to the tail of the dump truck, and a retaining plate is hinged to the other side of the screen box; one end of the retaining plate away from the screen box is connected by a chain.
[0017] In this solution, the L-shaped hook is set. During actual operation, the L-shaped hook can be fixed on the end beam of the dump truck's rear end to prevent the coarse-grained soil sorting device from being pushed away by the falling coarse-grained soil under the impact of the coarse-grained soil during the unloading process; the retaining plate is set to block the falling coarse-grained soil to prevent it from rushing out of the screen conveying mechanism due to inertia.
[0018] Further, the support seat includes four support columns which respectively support at the four corners of the screen box; a damping spring is provided at the top of each support column, and a movable hinge seat is supported on the top of the damping spring, and the movable hinge seat is hinged to the screen box.
[0019] In this solution, the movable hinge seat and the damping spring are designed to realize the elastic connection between the screen box and the support column, avoiding the vibration generated by the screen box during work from being transmitted to the support column.
[0020] Further, a universal wheel is provided at the bottom of each support column.
[0021] In this solution, the universal wheels are set. When the dump truck moves forward during unloading, the coarse-grained soil sorting device can also move synchronously with it, without the need for manual movement in the middle, with simple operation and strong practicability.
[0022] Further, a double-opening baffle is provided at the bottom of the screen box, and both ends of the double-opening baffle are respectively hinged to both sides of the screen box.
[0023] In this solution, the double-opening baffle is set, and the small-particle soil screened out falls from the middle of the double-opening baffle, making it more concentrated.
[0024] The beneficial effects of the present utility model are:
[0025] The coarse-grained soil sorting device provided by the present utility model combines the unloading process and the screening process of coarse-grained soil in the project, realizes screening while unloading, and does not require special screening of coarse-grained soil after unloading; simplifies the construction steps, saves labor costs, and significantly improves the construction efficiency.
[0026] In the coarse-grained soil sorting device provided by the utility model, a screen conveyor belt is designed. The vibrating motor drives the screen conveyor belt to move back and forth along the transverse guide rail, accelerating the screening process of small-particle soil during the movement. The driving motor drives the screen conveyor belt to rotate, and transports large-particle soil out from the side of the screen conveyor belt during the rotation. It can achieve the effect of automatically separating small-particle soil and large-particle soil after screening, with strong practicability and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

The following describes the specific embodiments of the present utility model to facilitate those skilled in the art to understand the present utility model. However, it should be clear that the present utility model is not limited to the scope of the specific embodiments.

[0036] As Figure 1As shown in the figure, this embodiment provides a coarse-grained soil sorting device fixed to the tail of a dump truck, which is used to screen coarse-grained soil during the unloading process of the dump truck. This coarse-grained soil sorting device can combine the unloading process and the screening process of coarse-grained soil, realizing screening while unloading, and there is no need to specifically screen the coarse-grained soil after unloading, simplifying the construction steps and improving the construction efficiency. Specifically, it includes:
[0037] A support base 6, a screen box 1, a transverse guide rail 2, a screen conveyor mechanism 3, a vibration mechanism 4, and a drive mechanism 5. A screen box 1 is arranged on the support base 6. There are two transverse guide rails 2 on both sides of the screen box 1, and a screen conveyor mechanism 3 is slidably arranged on the two transverse guide rails 2. The screen conveyor mechanism 3 is movably connected to the vibration mechanism 4, and the vibration mechanism 4 drives the screen conveyor mechanism 3 to vibrate along the transverse guide rail 2. The dump truck dumps the coarse-grained soil onto the screen conveyor mechanism 3. Under the vibration of the vibration mechanism 4, the small-particle soil in the coarse-grained soil on it passes through the screen conveyor mechanism 3, and the large-particle soil remains on the screening conveyor mechanism. A drive mechanism 5 is fixed on the screen conveyor mechanism 3, and the drive mechanism 5 drives the screen conveyor mechanism 3 to rotate. The large-particle soil remaining on the top of the screening conveyor mechanism is transported to one side of the screening conveyor mechanism, thus realizing the screening work of the coarse-grained soil. This screening method has high work efficiency, can screen the coarse-grained soil during the unloading process, and there is no need to dump the coarse-grained soil to a certain place and then transfer it to the screening device for screening again, reducing the work intensity.
[0038] As Figure 2 shown in the figure, the screen conveyor mechanism 3 includes a screen conveyor belt 31, a transmission wheel 32, a transmission belt 33, and a slider 34. The screen conveyor belt 31 is arranged on two transmission wheels 32, and one of the transmission wheels 32 is in transmission connection with a drive motor 51. The two transmission wheels 32 are in transmission connection through a transmission belt 33. There are two sliders 34 on both sides of the two transmission wheels 32, and the two ends of the two transmission wheels 32 are respectively rotatably arranged on the two sliders 34. The two sliders 34 are respectively slidably arranged on the two transverse guide rails 2. The drive motor 51 drives the transmission wheel 32 and the screen conveyor belt 31 arranged on the surface of the transmission wheel 32 to rotate, and the large-particle soil on the rotating screen conveyor belt 31 is transported out.
[0039] As Figure 3As shown in the figure, the vibration mechanism 4 includes a vibration motor 41, a crankshaft 42, and a connecting rod 43. The vibration motor 41 is arranged on a motor base 44 on one side of the sieve box 1. The fixed end of the crankshaft 42 is rotatably connected to the bottom of the motor base 44. The vibration motor 41 is connected to the fixed end of the crankshaft 42 through a belt. The rotating end of the crankshaft 42 is rotatably connected to one end of the connecting rod 43, and the other end of the connecting rod 43 is connected to the slider 34. The vibration motor 41 drives the crankshaft 42 to rotate around its fixed end. During the rotation, the crankshaft 42 pulls the slider 34 to move back and forth along the transverse guide rail 2 through the connecting rod 43, thereby driving the sieve belt 31 on the slider 34 to move back and forth, so as to realize the reciprocating vibration effect of the sieve belt 31. During the reciprocating vibration, the small particle soil on the surface of the sieve belt 31 quickly discharges from the pores of the sieve belt 31.
[0040] As Figure 4 shown in the figure, the driving mechanism 5 includes a driving motor 51. The driving motor 51 is fixedly installed on one of the sliders 34. The driving motor 51 is connected to one of the transmission wheels 32 through belt drive. When the slider 34 moves along the transverse guide rail 2, the driving motor 51 moves synchronously with it, ensuring that the transmission work of the sieve belt 31 during the vibration process is uninterrupted, and realizing a continuous screening process.
[0041] As Figure 5 shown in the figure, an L-shaped hook 11 is hinged on one side of the sieve box 1 connected to the tail of the dump truck, and a retaining plate 12 is hinged on the other side of the sieve box 1. One end of the retaining plate 12 away from the sieve box 1 is connected through a chain 13. The L-shaped hook 11 is provided. During actual operation, the L-shaped hook 11 can be fixed on the end beam of the dump truck tail to prevent the coarse-grained soil sorting device from being pushed away by the falling coarse-grained soil during the unloading process, as Figure 6 shown in the figure. The retaining plate 12 is provided. During work, the retaining plate 12 is turned up. The retaining plate 12 blocks the falling coarse-grained soil to prevent it from rushing out of the sieve conveyor mechanism 3 due to inertia. After work, the retaining plate 12 is put down to keep it parallel to the sieve box 1, saving space.
[0042] As another implementation manner of this embodiment, the sieve box 1 can also be directly fixed to the main frame under the dump truck carriage through a rope, as long as it can prevent the coarse-grained soil sorting device from being pushed away during the falling process of the coarse-grained soil.
[0043] The support seat 6 includes four support columns 61. The four support columns 61 respectively support at the four corners of the sieve box 1. A damping spring 62 is provided at the top of each support column 61. The top of the damping spring 62 supports a movable hinge seat 63, and the movable hinge seat 63 is hinged to the sieve box 1. The movable hinge seat 63 and the damping spring 62 are designed to realize the elastic connection between the sieve box 1 and the support column 61, and avoid the vibration generated by the sieve box 1 during work from being transmitted to the support column 61.
[0044] A universal wheel is provided at the bottom of each support column 61; when the dump truck moves forward during unloading, the coarse-grained soil sorting device can also move synchronously with it, without the need for manual movement in the middle, with simple operation and strong practicability.
[0045] A double-opening baffle 14 is provided at the bottom of the sieve box 1, and both ends of the double-opening baffle 14 are respectively hinged on both sides of the sieve box 1; by setting the double-opening baffle 14, the small-particle soil mass screened out falls from the middle of the double-opening baffle 14, making it more concentrated.
[0046] As an optimization of this embodiment, the sieve mesh conveyor belt 31 can adopt the Teflon sieve mesh - Teflon grid conveyor belt supplied by Juntao manufacturer.
[0047] The working principle of this embodiment is as follows:
[0048] When the coarse-grained soil sorting device provided in this embodiment is screening coarse-grained soil, first place the device horizontally on the ground to ensure that the support columns are in full contact with the ground, then turn up the retaining plate 12 and open the double-opening baffle 14; then fix it to the rear of the dump truck through the L-shaped hook 11 and prepare for unloading. The driver pulls up the hand brake valve of the dump truck to make it in the braking position, starts the vibration motor 41 and the drive motor 51, and starts unloading. During the unloading process, do not lift the carriage too high to prevent large-area unloading from blocking the sieve mesh conveyor belt 31.
[0049] After the coarse-grained soil falls onto the sieve mesh conveyor belt 31, the small-particle soil mass passes through the pores of the sieve mesh conveyor belt 31 and falls to the ground through the double-opening baffle 14; the large-particle soil mass cannot pass through the sieve mesh, is retained at the top of the sieve mesh conveyor belt 31, and is conveyed by the sieve mesh conveyor belt 31 to one side of the sieve mesh conveyor belt 31, thus realizing the separation of the small-particle soil mass and the large-particle soil mass.
[0050] Those of ordinary skill in the art will realize that the embodiments here are to help readers understand the principles of the present utility model, and it should be understood that the protection scope of the present utility model is not limited to such specific statements and embodiments. Those of ordinary skill in the art can make various other specific deformations and combinations that do not deviate from the essence of the present utility model based on these technical revelations disclosed in the present utility model, and these deformations and combinations are still within the protection scope of the utility model.
