[0043] See also Figure 1-11 The present invention provides a technical solution: a road and bridge construction loading machine, comprising a chassis 1, a conveying assembly 2 and a material-dropping assembly 4, the chassis 1 and the conveying assembly 2 are connected by an adjusting assembly 8, the material-dropping assembly 4 is installed at one end of the conveying assembly 2, a dust cover 3 is fixedly provided on the conveying assembly 2, the dust cover 3 and the material-dropping assembly 4 are connected by an elastic connecting cover 5, a dust collecting assembly 6 and a spraying assembly 7 are provided on the chassis 1, a dust collecting plate 31 and a spraying pipe 32 are provided on the inner side of the dust cover 3, a connecting pipe 33 is connected to the top of the dust collecting plate 31, the spraying pipe 32 is connected to a water distribution pipe 34, the water distribution pipe 34 is connected to a water inlet pipe 35, and the dust collecting assembly 6 includes A dust collecting box 61, a filter cartridge 62 is arranged on the outside of the dust collecting box 61, one end of the filter cartridge 62 is connected to the exhaust fan 63, the dust collecting box 61 and the connecting pipe 33 are connected via a dust suction hose 64, the spray assembly 7 includes a water storage tank 71, a water pump 72 is arranged on the outside of the water storage tank 71, the water pump 72 and the water inlet pipe 35 are connected via a water supply hose 73, the blanking assembly 4 includes a side plate 41 and a fixed cylinder 42, one end of the fixed cylinder 42 is provided with a corrugated hose 43, one end of the corrugated hose 43 is provided with a fixing ring 44, a driving device 45 is installed on the outer surface of the side plate 41, and the fixed cylinder 42 and the fixing ring 44 are connected via an adjusting screw 49.

[0044] Among them, Figure 2-3 As shown, the adjusting component 8 can flexibly adjust the angle of the conveying component 2. According to the use requirements, the conveying component 2 is adjusted to a specified angle through the adjusting component 8 to convey the raw materials. The raw materials are lifted to a specified height and then dropped to realize loading.

[0045] like Figure 5 , Figure 7 As shown, a dust cover 3 is added to the conveying component 2, and the dust cover 3 can be used as a cover body to prevent dust from overflowing during the conveying process. The dust suction plate 31 on the dust cover 3 is connected to the dust collecting component 6, and the exhaust fan 63 of the dust collecting component 6 is used to generate the required negative pressure during dust suction. When the exhaust fan 63 is working, the dust suction hose 64 generates a negative pressure adsorption force, so that the dust suction plate 31 generates a negative pressure adsorption force synchronously. The dust generated by the raw material during the conveying process enters the dust suction plate 31 under the action of the suction force, enters the dust suction hose 64 through the dust suction plate 31, and enters the dust collecting box 61 through the dust suction hose 64. The dust particles are trapped in the dust collecting box 61 by the filter cartridge 62, and the air is discharged normally through the exhaust fan 63, so as to realize the collection of flying dust, prevent the flying dust from polluting the environment, and ensure the cleanliness of the working environment.

[0046] like Figure 6 , Fig. 9 As shown, a spray pipe 32 is additionally provided on the dust cover 3, and the spray pipe 32 is connected to the spray assembly 7. The water pump 72 of the spray assembly 7 is used to transport water, and the spray water is transported to the water distribution pipe 34, and then diverted to the spray pipe 32 through the water distribution pipe 34, and finally sprayed with water mist through the spray pipe 32. The water mist acts on the surface of the raw materials to effectively suppress dust on the raw materials, thereby reducing the generation of flying dust.

[0047] The angle of the blanking component 4 relative to the conveying component 2 is adjustable. Without changing the inclination angle of the conveying component 2 , the final blanking position can be flexibly adjusted by adjusting the angle of the blanking component 4 .

[0048] like Figure 8 As shown, in some examples, a filter element is disposed inside the filter cartridge 62 , a discharge drawer 65 is built into the dust box 61 , and the discharge drawer 65 is connected to the dust box 61 via a slide rail, and the dust box 61 is fixedly disposed on the base frame 1 .

[0049] Among them, Figure 6-7 As shown, the dust collected by the dust collecting plate 31 is concentrated into the dust collecting box 61 and collected by the dust collecting box 61. A handle is welded and fixed on the outer surface of the unloading drawer 65. When the collected dust needs to be processed, a certain external force is applied to the unloading drawer 65 to pull out the unloading drawer 65, which facilitates the subsequent processing of the dust.

[0050] In some examples, a bottom plate 74 is provided at the bottom end of the water tank 71, and the bottom plate 74 is fixedly connected to the base frame 1. A water supply port 75 is provided on one side of the upper end of the water tank 71. Two groups of spray pipes 32 are provided, and the two groups of spray pipes 32 are respectively located on both sides of the dust collection plate 31, and multiple groups of spray heads 36 are provided on the spray pipes 32.

[0051] like Figure 6 As shown, when the liquid level inside the water tank 71 is insufficient, water can be replenished in time through the water replenishment port 75, and multiple groups of spray heads 36 are evenly spaced along the axial direction of the spray pipe 32 to spray evenly. Two groups of spray pipes 32 can spray the raw materials over a large area, and the water mist acts on the surface of the raw materials to effectively suppress dust on the raw materials, thereby reducing the generation of flying dust.

[0052] In some examples, such as Figure 2 As shown, the conveying assembly 2 includes a conveying frame 21, a motor reducer 22, a conveying roller and a conveying belt 23. The motor reducer 22 is installed and fixed on the conveying frame 21, the output shaft of the motor reducer 22 is connected to the conveying roller, and the conveying belt 23 is located outside the conveying roller.

[0053] Among them, the motor reducer 22 drives the conveyor roller when working, and the conveyor roller drives the conveyor belt 23 to move. When the raw material is placed on the conveyor belt 23, it moves synchronously with the conveyor belt 23, and the raw material is transported by the conveying component 2 to the specified position.

[0054] In some examples, such as Figure 3 As shown, the adjustment assembly 8 includes a fixed frame 81, a support frame 82 and a hydraulic cylinder 83. The fixed frame 81 is installed and fixed on one side of the lower end of the conveyor frame 21, and the support frame 82 is installed and fixed on one side of the upper end of the base frame 1. The support frame 82 and the fixed frame 81 are rotatably connected through a rotating shaft. The fixed frame 81 of the conveyor frame 21 can rotate relative to the support frame 82 of the base frame 1.

[0055] In some examples, such as Figure 4 As shown, one end of the hydraulic cylinder 83 is connected to a connecting head 87, and a slide 84 is provided at the lower end of the conveyor frame 21. A slide rod 85 is provided on the slide 84, and a slide seat 86 is slidably sleeved on the slide rod 85. The slide seat 86 is rotatably connected to the connecting head 87 through a rotating shaft. The slide seat 86 can slide along the slide rod 85 and can rotate relative to the connecting head 87.

[0056] The working principle of the regulating component 8 is:

[0057] like Figure 3 and Figure 4As shown, the hydraulic cylinder 83 drives the connecting head 87 at one end to move, drives the slide 84 through the connecting head 87, and then drives the conveying component 2 to deflect with the rotating axis of the support frame 82 as the base point, so as to flexibly adjust the inclination angle of the conveying component 2. The deflection and inclination angle of the conveying component 2 is precisely controlled by the telescopic stroke of the hydraulic cylinder 83.

[0058] In some examples, such as Figure 1-3 As shown, rollers 11 are provided at the corners of the base frame 1. The provision of the rollers 11 facilitates the movement of the entire loader and the adjustment of the working position of the loader.

[0059] By adopting the above technical solution:

[0060] The dust suction plate 31 on the dust cover 3 is connected to the dust collecting assembly 6, and the exhaust fan 63 generates suction when working. The dust generated by the raw materials during the transportation process is concentrated into the dust suction plate 31 under the action of the suction, enters the dust suction hose 64 through the dust suction plate 31, and enters the dust collecting box 61 through the dust suction hose 64. The dust particles are trapped in the dust collecting box 61 by the filter cylinder 62, and the air is discharged normally through the exhaust fan 63, so as to realize the collection of flying dust, prevent the flying dust from polluting the environment, and ensure the cleanliness of the working environment.

[0061] The spray pipe 32 on the dust cover 3 is connected to the spray assembly 7, and water is transported by the water pump 72, and finally water mist is sprayed through the spray pipe 32. The water mist acts on the surface of the raw material to effectively suppress dust on the raw material, thereby reducing the generation of flying dust.

[0062] Embodiment 2:

[0063] Based on Example 1, this example introduces a specific structure of a blanking assembly 4 in a road and bridge construction charging machine, such as Fig.10 and Fig.11 As shown, a first fixing block 47 is welded and fixed on the outer surface of the fixing cylinder 42, a second fixing block 48 is welded and fixed on the outer surface of the fixing ring 44, an adjusting screw 49 passes through the first fixing block 47 and the second fixing block 48, and the adjusting screw 49 is threadedly connected to the first fixing block 47.

[0064] A first fixing block 47 is welded on the outer surface of the fixing tube 42. This welding method ensures a firm connection between the two, so that when the angle or length of the blanking assembly is adjusted, the fixing tube 42 can remain stable and is not easily deformed or loosened. Similarly, a second fixing block 48 is also welded on the outer surface of the fixing ring 44. This design is also to ensure the stability and reliability of the connection. When adjusting the blanking assembly, the fixing ring 44 can move together with the second fixing block 48 to ensure the coordination of the entire blanking assembly.

[0065] The adjusting screw 49 passes through the first fixing block 47 and the second fixing block 48 and forms a threaded connection with the first fixing block 47, allowing the user to change its position relative to the first fixing block 47 by rotating the adjusting screw 49, thereby achieving precise adjustment of the angle and length of the blanking assembly.

[0066] By applying a certain external force to the adjusting screw 49, the position of the adjusting screw 49 relative to the first fixed block 47 can be adjusted. The fixing tube 42 and the fixing ring 44 are connected by a corrugated hose 43. The corrugated hose 43 has a certain elasticity and can be freely expanded and contracted within a certain range.

[0067] By adjusting the telescopic length of the corrugated hose 43, the distance between the fixed cylinder 42 and the fixed ring 44 is adjusted accordingly, that is, the total length of the blanking assembly 4 is adjusted accordingly. The fixed cylinder 42 is the feeding end, and the fixed ring 44 is the discharging end. By adjusting the total length of the blanking assembly 4, the final blanking position of the loader can be flexibly adjusted.

[0068] The corrugated hose 43 has a certain elasticity and can freely expand and contract within a certain range, so that the distance between the fixing tube 42 and the fixing ring 44 can be adjusted as needed, thereby realizing flexible adjustment of the total length of the blanking assembly.

[0069] In some examples, such as Fig.10 and Fig.11 As shown, two sets of locking nuts 410 are threadedly sleeved on the adjusting screw 49 , and the two sets of locking nuts 410 are respectively located on both sides of the second fixing block 48 .

[0070] Among them, applying a certain external force to the two sets of locking nuts 410 can rotate the two sets of locking nuts 410, and then adjust the positions of the two sets of locking nuts 410. The fixing ring 44 is limited and fixed by the two sets of locking nuts 410 to keep the blanking assembly 4 stable.

[0071] The fixing ring 44 is limited and fixed by two sets of locking nuts 410, which can significantly enhance the overall stability of the blanking assembly 4. During the operation of the loader, even if it is subjected to a large impact force or vibration, the blanking assembly can remain stable and is not prone to loosening or displacement, thereby ensuring the continuity and accuracy of the loading operation.

[0072] The design of two sets of locking nuts 410 allows the user to fix the position of the adjustment screw 49 by tightening the nuts after adjusting the angle and length of the blanking assembly 4, which not only ensures the flexibility of adjustment, but also ensures the stability after adjustment, allowing the user to easily adjust the posture of the blanking assembly according to actual needs.

[0073] In some examples, such as Fig.10 and Fig.11As shown, the output shaft of the driving device 45 is connected to the driving shaft 46, one end of the driving shaft 46 is fixedly connected to the fixed cylinder 42, one end of the elastic connecting cover 5 is fixedly connected to the dust cover 3, and the other end of the elastic connecting cover 5 is fixedly connected to the fixed cylinder 42 of the blanking assembly 4.

[0074] Among them, Fig.10 and Fig.11 As shown, when the driving device 45 is working, it drives the driving shaft 46 at one end thereof, drives the fixed cylinder 42 through the driving shaft 46, drives the fixed ring 44 through the fixed cylinder 42, and then flexibly adjusts the inclination angle of the blanking component 4 relative to the conveying component 2, that is, flexibly adjusts the final blanking angle of the loader.

[0075] The driving device 45 can drive the driving shaft 46 on its output shaft to rotate. Since the driving shaft 46 is fixedly connected to the fixed cylinder 42, it can drive the entire blanking assembly 4 to rotate around the driving shaft 46. The construction personnel can flexibly adjust the inclination angle of the blanking assembly 4 according to actual needs, thereby accurately controlling the blanking direction and position of the raw materials.

[0076] like Fig.10 and Fig.11 As shown, the elastic connecting cover 5 has a certain elastic deformation ability, and can be adaptively adjusted according to the tilt angle of the blanking assembly 4 to always connect the dust cover 3 and the fixed tube 42 of the blanking assembly 4.

[0077] By adopting the above technical solution:

[0078] The total length and inclination angle of the blanking component 4 are flexibly adjustable. Without changing the inclination angle of the conveying component 2, the final blanking position can be flexibly adjusted by adjusting the angle of the blanking component 4, thereby improving flexibility during use.

[0079] In actual construction, loaders often need to face complex and changeable working environments, and the drop point may change frequently due to construction needs. By flexibly adjusting the angle of the drop component 4, the drop position can be quickly adjusted without interrupting the conveying operation, avoiding the time and resources wasted due to repositioning the loader, thereby greatly improving the construction efficiency. Road and bridge construction is often restricted by various factors such as terrain and space. The angle adjustability of the drop component 4 enables the loader to better adapt to various construction scenarios. Whether it is a narrow space or complex terrain, accurate drop can be achieved by adjusting the drop angle, which enhances the versatility and adaptability of the loader.

[0080] The loader discharges materials through the blanking component 4. When discharging materials, the angle and length of the blanking component 4 can be adjusted accordingly according to the blanking position requirements to make the blanking component 4 adapt to the blanking position. When blanking, a cover structure is formed by the fixed cylinder 42, the corrugated hose 43 and the fixed ring 44 to cover the blanking path, thereby further suppressing dust and reducing the generation of flying dust.

[0081] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
