Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paver equipment, in particular to an angle-adjustable paver reverse blade mounting structure. Background Art
[0002] The paver is equipped with reverse blades on both sides of the material distribution box, which are responsible for conveying the material to the middle of the paver to avoid the formation of a paving segregation zone in the middle. Different materials have different fluidity and different requirements for the reverse blade angle. For example, water-stabilized soil (cement-stabilized soil) has poor fluidity and requires a large-angle reverse blade; asphalt has good fluidity and requires a small-angle reverse blade.
[0003] At present, the reverse blade is directly installed on the material distribution rod, and the blade installation surface matches the outer surface of the material distribution rod, wherein the installation angle of the reverse blade is fixed and cannot be adjusted. The paver is relatively limited when conveying materials through the reverse blade, especially when conveying materials with different fluidity, it is necessary to remove the original reverse blade and reinstall the reverse blade with the corresponding angle, which has low work efficiency and high labor intensity. Utility Model Content
[0004] The embodiment of the present application provides an adjustable angle reverse blade installation structure for a paving machine, which can flexibly adjust the installation angle of the reverse blade according to different paving materials. It is easy to operate, can effectively improve paving efficiency, ensure paving quality, and reduce labor intensity.
[0005] The embodiment of the present application provides an angle-adjustable reverse blade installation structure for a paver, comprising a rotating shaft, a transition pad, and a reverse blade, wherein the rotating shaft is installed on a material distribution box, and the reverse blade is connected to the rotating shaft through the transition pad, so that the paver can drive the reverse blade to rotate through the rotating shaft during operation to achieve material distribution, wherein the reverse blade is connected to the transition pad in a manner that the installation angle can be adjusted;
[0006] The transition pad has a first connecting end and a second connecting end relative to each other, wherein the first connecting end is provided with an arc surface that cooperates with the rotating shaft, and the second connecting end and the mounting end of the reverse blade are correspondingly provided with a first matching structure and a second matching structure, and the first matching structure and the second matching structure cooperate so that the reverse blade can rotate in a directional manner at the second connecting end.
[0007] In a possible implementation, the angle-adjustable paver reverse blade mounting structure also includes a connecting piece to connect the rotating shaft, the transition pad and the reverse blade, or to connect the rotating shaft, the transition pad and the reverse blade after the reverse blade is rotated into place.
[0008] In a possible implementation, the first matching structure is implemented as a plurality of protrusions evenly distributed along the circumference of the second connecting end, and the second matching structure is implemented as a plurality of grooves evenly distributed along the circumference of the mounting end of the reverse blade.
[0009] In a possible implementation, the cross-section of the protrusion is trapezoidal, and the upper base of the trapezoid is located at an end away from the transition pad.
[0010] In a possible implementation, the depth of the groove is 8 mm-12 mm, and the angle of the inclined surface of the groove is 35°-50°.
[0011] In a possible implementation, the first matching structure is implemented as a plurality of grooves evenly distributed along the circumference of the second connecting end, and the second matching structure is implemented as a plurality of protrusions evenly distributed along the circumference of the mounting end of the reverse blade.
[0012] In a possible implementation, the second connecting end and the mounting end of the reverse blade are both planar structures, and the first matching structure and the second matching structure are both arranged on corresponding planar structures.
[0013] In a possible implementation, the reverse blade is provided with a connecting channel on a side close to the mounting end, and a mounting opening vertically penetrating the reverse blade is provided at the bottom of the connecting channel. The connecting member includes a connecting bolt and a connecting nut, and the connecting bolt vertically penetrates the rotating shaft and the transition pad from a side of the rotating shaft away from the transition pad and extends into the mounting opening. The connecting nut is located in the mounting opening and is threadedly connected to the connecting bolt.
[0014] Beneficial effect: Compared with the prior art, the adjustable angle paver reverse blade installation structure provided in the present application abandons the design of directly connecting the conventional reverse blade to the rotating shaft, and transitions between the rotating shaft and the reverse blade are performed by setting a transition pad. At the same time, the reverse blade is connected to the transition pad in a manner that allows the paver to adjust the installation angle of the reverse blade flexibly according to the different paving materials, which can effectively improve the paving efficiency, ensure the paving quality, and reduce labor intensity.

[0021] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0022] refer to Figures 1 to 3 The embodiment of the present application provides an adjustable angle reverse blade installation structure for a spreading machine, comprising a rotating shaft 10, a transition pad 20 and a reverse blade 30, wherein the rotating shaft 10 is installed on a material distribution box, and the reverse blade 30 is connected to the rotating shaft 10 through the transition pad 20, so that when the spreading machine is working, the reverse blade 30 can be driven to rotate by the rotating shaft 10 to achieve material distribution, wherein the reverse blade 30 is connected to the transition pad 20 in a manner that the installation angle can be adjusted. In this way, when the spreading machine is processing materials with different fluidities, the installation angle of the reverse blade 30 can be directly adjusted on the transition pad 20, which is easy to operate and avoids the trouble of replacing the reverse blade, which can effectively improve work efficiency and ensure paving quality.
[0023] More specifically, the transition pad 20 has a first connecting end 21 and a second connecting end 22 relative to each other, wherein the first connecting end 21 is provided with an arc surface that matches the rotating shaft 10, so that the transition pad 20 can be well-fitted and connected to the rotating shaft. In addition, the second connecting end 22 and the mounting end of the reverse blade 30 are correspondingly provided with a first matching structure 221 and a second matching structure 31, and at the same time, the first matching structure 221 and the second matching structure 31 match each other, so that the reverse blade 30 can be directional rotated at the second connecting end 22, and the adjustable angle paver reverse blade mounting structure also includes a connecting member 40 to connect the rotating shaft 10, the transition pad 20 and the reverse blade 30, or to connect the rotating shaft 10, the transition pad 20 and the reverse blade 30 after the reverse blade 30 is rotated into place, so as to ensure the installation firmness of the reverse blade 30 on the transition pad 20.
[0024] In one embodiment, the first mating structure 221 is implemented as a plurality of protrusions evenly distributed along the circumference of the second connecting end 22 , and correspondingly, the second mating structure 31 is implemented as a plurality of grooves evenly distributed along the circumference of the mounting end of the reverse blade 30 .
[0025] Further preferably, the cross-section of the protrusion is trapezoidal, and the upper base of the trapezoid is located at an end away from the transition pad 20, so that the protrusion can be connected to the transition pad 20 through the lower base with a larger contact area to ensure the connection strength of the protrusion, and at the same time can cooperate with the groove through the upper base with a smaller contact area to facilitate the rotation of the reverse blade 30 to adjust the angle. In addition, the protrusion with a trapezoidal cross-section also has better structural strength as a whole, and can ensure the installation stability of the reverse blade 30 after cooperating with the groove.
[0026] In another embodiment, the first mating structure 221 is implemented as a plurality of grooves evenly distributed along the circumference of the second connecting end 22, and the second mating structure 31 is implemented as a plurality of protrusions evenly distributed along the circumference of the mounting end of the reverse blade 30. This mating method is similar to the aforementioned mating method of the protrusions and grooves and will not be described in detail here.
[0027] In one embodiment, the second connecting end 22 and the mounting end of the reverse blade 30 are both planar structures, and the first matching structure 221 and the second matching structure 31 are both arranged on corresponding planar structures, so that the contact area between the transition pad 20 and the reverse blade 30 can be increased as much as possible within a limited space. After the reverse blade 30 is installed in place, the reverse blade 30 can be more firmly installed on the transition pad 20 and has a longer service life.
[0028] In one embodiment, the reverse blade 30 is provided with a connection channel 301 on a side close to the mounting end, and a mounting opening 302 is provided at the bottom of the connection channel 301 and vertically penetrates the reverse blade 30. In addition, the connecting member 40 includes a connecting bolt 41 and a connecting nut 42, wherein the connecting bolt 41 vertically penetrates the rotating shaft 10 and the transition pad 20 from a side of the rotating shaft 10 away from the transition pad 20 and extends into the mounting opening 302, and the connecting nut 42 is located in the mounting opening 302 and is threadedly connected with the connecting bolt 41. When the mounting angle of the reverse blade 30 needs to be adjusted, it is only necessary to reversely rotate the connecting nut 42 to disengage the second matching structure 31 on the reverse blade 30 from the first matching structure 221 on the transition pad 20, and then rotate the reverse blade 30. After rotating to the right position, the second matching structure 31 and the first matching structure 221 are matched again, and then the connecting nut 42 is tightened. The operation is very convenient, and there is no need to completely disassemble the reverse blade 30 and then replace it with a new reverse blade 30.
[0029] According to the needs and the actual area size, 8-16 protrusions and grooves can be evenly arranged accordingly, wherein the depth of the groove can be 8mm-12mm, such as 10mm, and the angle of the inclined surface of the groove is 30°-50°, such as 45°.
