[0032] Example 1

[0033] The embodiment of the present invention provides a quick unloading device for a dump truck, such as Figure 1-Figure 9 As shown, it includes: a dump truck compartment 1, a discharge port 2 is arranged on one side of the dump truck compartment 1, a driving motor 3 is arranged on the outer wall of the dump truck compartment 1 away from the discharge port 2, a screw 4 is arranged in the dump truck compartment 1, one end of the screw 4 is connected to the output end of the driving motor 3, and the other end of the screw 4 is connected to the inner wall of the dump truck compartment 1, a discharge plate 5 is arranged in the dump truck compartment 1, the discharge plate 5 slides along the length direction of the dump truck compartment 1, a threaded hole is arranged in the discharge plate 5, the discharge plate 5 is threadedly connected to the screw 4 through the threaded hole, a cleaning groove 6 is arranged on the outer periphery of the discharge plate 5, a cleaning component is arranged in the cleaning groove 6, and the cleaning component is used to clean the inner wall of the dump truck compartment 1.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the dump truck compartment 1 is used for loading materials. After reaching the unloading position, the drive motor 3 is started. The drive motor 3 can drive the screw 4 to rotate. The rotation of the screw 4 drives the unloading plate 5 to slide inside the dump truck compartment 1. The unloading plate 5 drives the material in the dump truck compartment 1 to move toward the unloading port 2. The material is pushed out from the unloading port 2 by the push of the unloading plate 5 to achieve rapid unloading. During the unloading process, the cleaning component in the cleaning groove 6 of the unloading plate 5 can clean the inner wall of the dump truck compartment 1, thereby removing the residual material on the inner wall of the dump truck compartment 1, improving the unloading effect, and quickly unloading through the unloading device, reducing the labor intensity of the staff during unloading, and improving the unloading efficiency.

[0035] Example 2

[0036] On the basis of the above-mentioned embodiment 1, Figure 1-Figure 4As shown, the cleaning assembly includes a plurality of cleaning plates 7, which are arranged at equal intervals along the length direction of the cleaning groove 6. A plurality of bristles 8 are arranged on one side of the cleaning plate 7 close to the inner wall of the dump truck compartment 1, and an adjusting column 9 is arranged on the other side of the cleaning plate 7. The adjusting column 9 is slidably arranged in the adjusting hole 10. The adjusting column 9 is connected to the adjusting hole 10 through a compression spring. The adjusting hole 10 is arranged in the unloading plate 5, and one end of the adjusting hole 10 is connected to the cleaning groove 6.

[0037] The working principle and beneficial effects of the above technical scheme are as follows: when the unloading plate 5 slides along the inner wall of the dump truck compartment 1, the cleaning components in the cleaning groove 6 of the unloading plate 5 move synchronously, and under the action of the compression spring, the bristles 8 can be completely fitted with the inner wall of the dump truck compartment 1. When encountering a protrusion, the cleaning plate 7 can drive the adjusting column 9 to slide inward in the adjusting hole 10, and the compression spring is compressed, so that the cleaning plate 7 can smoothly pass through the protrusion of the inner wall of the dump truck compartment 1. When encountering a recessed part, under the action of the compression spring, the adjusting column 9 slides outward in the adjusting hole 10 and drives the cleaning plate 7 to move toward the recessed part, so that the bristles 8 enter the recessed part, and with the movement of the unloading plate 5, the bristles 8 sweep out the materials accumulated in the recessed part of the inner wall of the dump truck compartment 1, reducing the residual materials, thereby improving the unloading effect, and no manual cleaning of the dump truck compartment 1 is required, which reduces the labor intensity of the staff and greatly improves the unloading efficiency.

[0038] Example 3

[0039] On the basis of Example 1 or 2, Figure 1 As shown, a dump truck rear door 11 is arranged outside the discharge port 2 .

[0040] The working principle and beneficial effects of the above technical solution are as follows: a dump truck rear door 11 is arranged outside the discharge port 2; during the transportation of the dump truck, the dump truck rear door 11 is used to block the discharge port 2 to prevent materials from flowing out of the discharge port 2; during the unloading process, the dump truck rear door 11 is opened to allow materials to flow out of the dump truck rear door 11, thereby completing rapid unloading.

[0041] Example 4

[0042] On the basis of any one of Examples 1-3, Figure 1-Figure 9As shown, sliding cavities 12 are arranged inside the front and rear side walls of the dump truck compartment 1, and a plurality of blowing assemblies are arranged on the inner wall of the dump truck compartment 1, one end of the blowing assemblies is communicated with the interior of the dump truck compartment 1, and the other end of the blowing assemblies is communicated with the interior of the sliding cavity 12, a ventilation plate 13 is slidably arranged in the sliding cavity 12, the side wall of the ventilation plate 13 is connected to the output end of the electric push rod 14, and the other end of the electric push rod 14 is connected to the inner wall of the sliding cavity 12, an air storage cavity 15 is arranged in the ventilation plate 13, and a plurality of air outlet holes 16 corresponding to the air blowing assemblies are arranged on one side of the ventilation plate 13 close to the blowing assemblies, and one end of the air outlet holes 16 is communicated with the interior of the air storage cavity 15, and an air pump 17 is arranged on the outer wall of the dump truck compartment 1, and the output end of the air pump 17 is communicated with the air storage cavity 15 through a telescopic hose.

[0043] The working principle and beneficial effects of the above technical solution are as follows: a plurality of blowing assemblies are arranged on the inner walls of the front and rear sides of the dump truck compartment 1, and the plurality of blowing assemblies are distributed in a rectangular array. A hollow sliding cavity 12 is arranged inside the side wall of the dump truck compartment 1, and a vent plate 13 is slidably arranged inside the sliding cavity 12. An air storage cavity 15 is arranged inside the vent plate 13, and the air storage cavity 15 is connected with the interior of the sliding cavity 12 through an air outlet 16. An air pump 17 is arranged outside the dump truck compartment 1. When the air pump 17 is started, air can be inflated into the air storage cavity 15 through a telescopic hose. When no gas is introduced, the air inlet 18 and the air outlet 16 on the side wall of the air plate 13 are arranged alternately. At this time, the air inlet 18 cannot be connected with the input end of the blowing assembly. When the air pump 17 is started, the air plate 13 is driven to slide in the sliding cavity 12 by the electric push rod 14, so that the air outlet 16 and the input end of the blowing assembly are connected. The gas filled in the air storage chamber 15 is connected, and can flow out through the air outlet 16 and be blown into the interior of the dump truck compartment 1 through the blowing component. During the unloading process, the blown-in gas can blow away part of the material remaining on the inner wall of the dump truck compartment 1, thereby further improving the unloading effect and reducing the residual material, and the blown-out gas can accelerate the outflow of the material, further improving the unloading efficiency; a heating device is also arranged in the air storage chamber 15. During the transportation of materials, the heating device and the air pump 17 are started, and the gas of a preset temperature can be blown into the interior of the dump truck compartment 1 through the blowing component, thereby keeping the material dry, avoiding the adhesion of easily sticky materials such as cement due to moisture, ensuring the quality of the material, reducing the possibility of material agglomeration during transportation, and no jamming problem will occur due to material agglomeration during unloading, thereby ensuring the unloading effect.

[0044] Example 5

[0045] On the basis of Example 4, Figure 1-Figure 9As shown, the blowing assembly includes an air inlet hole 18, an air inlet flow channel 19 and an air blowing hole 20 arranged on the inner wall of the dump truck compartment 1, the air blowing hole 20 is located below the air inlet hole 18, one end of the air blowing hole 20 is connected to the interior of the dump truck compartment 1, the other end of the air blowing hole 20 is connected to one end of the air inlet flow channel 19, the other end of the air inlet flow channel 19 is connected to one end of the air inlet hole 18, and the other end of the air inlet hole 18 is connected to the interior of the sliding cavity 12;

[0046] An air blowing mechanism is arranged in the air blowing hole 20, and the air blowing mechanism includes an air baffle plate 21, which is arranged in the air blowing hole 20, and the outer periphery of the air baffle plate 21 is slidably connected to the inner wall of the air blowing hole 20, and the air baffle plate 21 is connected to the inner wall of the air blowing hole 20 close to the sliding cavity 12 through a return spring 22, and an air release hole 23 is arranged on the side of the air baffle plate 21 close to the sliding cavity 12, and a first blowing flow channel 24 is arranged in the air baffle plate 21, and one end of the first blowing flow channel 24 is connected to the air release hole 23, and a push block 25 is arranged at the bottom of the side of the air baffle plate 21 away from the sliding cavity 12, and the bottom wall of the push block 25 is slidably connected to the bottom wall of the air blowing hole 20, and the cross-section of the push block 25 is a right triangle, and a second blowing flow channel 26 is arranged in the push block 25, and the second blowing flow channel 26 is horizontally arranged, and one end of the second blowing flow channel 26 is connected to the air blowing hole 20, and the other end of the second blowing flow channel 26 is connected to the first blowing flow channel 24;

[0047] A material baffle plate 27 is set in the blowing hole 20, and the material baffle plate 27 is located on the side of the air baffle plate 21 away from the sliding cavity 12. The lower end of the material baffle plate 27 is adapted to the upper surface of the push block 25, and the upper end of the material baffle plate 27 is slidably set in the mounting hole 28. The mounting hole 28 is set inside the side wall of the dump truck compartment 1, and the material baffle plate 27 is connected to the inner wall of the mounting hole 28 through a first connecting spring 29.

[0048] The working principle and beneficial effects of the above technical solution are as follows: after the air pump 17 is started, the gas first enters the air storage cavity 15 of the air vent plate 13, and then flows out through the multiple air outlet holes 16. The outflowing gas passes through the air inlet hole 18 and the air inlet flow channel 19 in turn and is blown into the interior of the dump truck compartment 1 from the air blowing hole 20. In order to prevent the material from entering the air inlet flow channel 19, an air baffle plate 21 is slidably arranged in the air blowing hole 20. The outer periphery of the air baffle plate 21 is adapted to the inner wall of the air blowing hole 20, thereby blocking the material from flowing into the air inlet flow channel 19 and ensuring smooth air intake. The gas entering the air blowing hole 20 through the air inlet flow channel 19 can enter the air discharge hole 23 of the air baffle plate 21, and then flows through the first blowing flow channel 24 and the second blowing flow channel 25 of the push block 25. 6 outflow, the outflowing high-speed gas can be blown into the dump truck compartment 1, thereby blowing the material, accelerating the unloading, improving the unloading efficiency, and realizing the rapid unloading of the unloading device. The materials accumulated in the concave part of the dump truck compartment 1 will also be blown out by the high-speed gas and flow out from the unloading port 2 driven by the bristles 8, further improving the cleaning effect, reducing the residual materials after unloading, and further improving the unloading effect. A baffle plate 27 is also arranged in the blowing hole 20, and the baffle plate 27 is located on the side of the air baffle plate 21 away from the sliding cavity 12. A second inclined surface is arranged at the lower end of the baffle plate 27, and a first inclined surface is arranged at the upper end of the push block 25. The second inclined surface at the lower end of the baffle plate 27 is slidably connected with the first inclined surface at the upper end of the push block 25, and no gas is introduced. When the first connecting spring 29 is activated, the lower end of the baffle plate 27 abuts against the upper end of the push block 25. At this time, the output end of the second blowing flow channel 26 is blocked, and the materials inside the dump truck compartment 1 are blocked by the baffle plate 27, and the materials cannot enter the second blowing flow channel 26, preventing the second blowing flow channel 26 from being blocked. When the inflation pump 17 is started to pass high-pressure gas, the high-pressure gas enters the blowing hole 20 and can drive the baffle plate 21 to slide in the blowing hole 20. The reset spring 22 is stretched, and the baffle plate 21 drives the push block 25 to slide along the bottom wall of the blowing hole 20. The push block 25 drives the baffle plate 27 to slide into the mounting hole 28, and the first connecting spring 29 is compressed until the output end of the second blowing flow channel 26 is connected to the blowing hole 20. , the high-pressure gas is quickly blown out through the output end of the second blowing flow channel 26, and the high-pressure gas is quickly blown into the dump truck compartment 1 to blow the material. Since the second blowing flow channel 26 has high-pressure gas blown out, the material in the dump truck compartment 1 cannot block the second blowing flow channel 26, thereby ensuring the smooth flow of the second blowing flow channel 26. After the blowing is completed, the pressure in the blowing hole 20 is reduced, and under the action of the return spring 22, the air baffle plate 21 returns to its original position. At the same time, under the action of the first connecting spring 29, the lower end of the material baffle plate 27 is always in contact with the first inclined surface at the upper end of the push block 25, and the material attached to the upper surface of the push block 25 is scraped off by sliding, thereby improving the cleanliness of the surface of the push block 25 and preventing the material from entering between the material baffle plate 27 and the air baffle plate 21.

[0049] Example 6

[0052] One end of the air outlet pipe 30 close to the air inlet hole 18 is set to be hemispherical, and one end of the air inlet hole 18 close to the air outlet pipe 30 is set to have a connecting hole 34 matched with the end of the air outlet pipe 30 .

[0053] The working principle and beneficial effects of the above technical solution are as follows: when no gas is introduced, the air inlet holes 18 and the air outlet holes 16 on the side wall of the air vent plate 13 are arranged alternately, and at this time, the air inlet holes 18 and the air outlet holes 16 cannot be connected. When the air pump 17 is started, the air vent plate 13 is driven to slide in the sliding cavity 12 by the electric push rod 14, so that the air inlet holes 18 are connected with the air outlet holes 16. At this time, the retaining ring 32 located in the air outlet hole 16 moves toward the air inlet hole 18 under the action of the second connecting spring 33, and the retaining ring 32 drives the end of the air outlet pipe 30 to slide into the connecting hole 34, and the air outlet is The end of the air pipe 30 is set to be hemispherical, and the inner wall of the connecting hole 34 is matched with the outer wall of the end of the air outlet pipe 30, which can improve the sealing performance of the air outlet pipe 30 and the connecting hole 34. The gas inside the air storage chamber 15 stably flows into the air inlet 18 from the outlet flow channel 31, reducing gas leakage, ensuring that the high-pressure gas stably blows the materials inside the dump truck compartment 1. After the ventilation is stopped, the ventilation plate 13 is controlled to slide by the electric push rod 14, so that the air inlet 18 and the air outlet 16 are offset again, and the air outlet pipe 30 can slide out of the connecting hole 34 for later reuse.
