Description

Technical Field

[0001] The utility model specifically relates to a feeding structure for jointly using a high modulus agent and lignin fiber. Background Technique

[0002] In road engineering, it is becoming more and more common to use high modulus agents and lignin fibers for road construction. Among them, the high modulus agent is a modified additive used to improve the stiffness modulus of asphalt mixtures. As a material widely used for paving roads, it is commonly used in the middle surface layer of roads, and its performance directly affects the quality and service life of the road surface. The lignin fiber is commonly used for paving the upper surface layer of roads, which can effectively prevent the coating from cracking, improve water retention, and enhance the stability of production and the suitability of construction.

[0003] At present, before using high modulus agents and lignin fibers, they need to be taken out of the ton bags and put into the asphalt mixture for uniform dispersion. However, the existing feeding devices for high modulus agents or lignin fibers cannot control the particle size of high modulus agents or lignin fibers, and some high modulus agents or lignin fibers that are affected by moisture and agglomerated are easily mixed in, resulting in unstable quality. Moreover, high modulus agents or lignin fibers need to be taken out of the ton bags and poured into the hopper, which takes a lot of time and has low work efficiency.

[0004] Therefore, it is necessary to invent a feeding structure for jointly using a high modulus agent and lignin fiber to solve the above problems. Content of the Utility Model

By setting a screen above the hopper, the particle size of the high modulus agent or lignin fiber at the top can be screened, ensuring the uniformity and quality stability of the high modulus agent or lignin fiber, and enabling the middle surface layer or upper surface layer of the road to have good quality and stable performance during manufacturing. Further, by installing a breaking body inside the hopper, the ton bag containing the high modulus agent or lignin fiber can be directly punctured when it is above the screen, saving time and effort and having high work efficiency.

The screening component includes a lower frame plate installed on the periphery of the top of the hopper, an upper frame plate connected to the lower frame plate by hinges, and a screen mesh disposed between the upper frame plate and the lower frame plate, for screening the high modulus agent or lignin fiber entering the interior of the hopper;

[0010] A breaking component is further provided inside the hopper. The breaking component has a breaking body that penetrates through the mesh holes of the screen mesh and is located above the screen mesh, for puncturing the ton bags containing high modulus agent or lignin fiber.

[0031] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0032] The present utility model provides a feeding structure for sharing high modulus agent and lignin fiber integrally as shown in Figures 1-5 , including a support 1 and a hopper 2 provided on the support 1;

[0033] A screening component is provided at the top of the hopper 2. The screening component includes a lower frame plate 31 installed on the periphery of the top of the hopper 2, an upper frame plate 32 connected to the lower frame plate 31 by hinges, and a screen 33 disposed between the upper frame plate 32 and the lower frame plate 31 for screening the high modulus agent or lignin fiber entering the interior of the hopper 2;

[0034] A breaking component 4 is further provided inside the hopper 2. The breaking component 4 has a breaking body 41 that penetrates through the mesh holes of the screen 33 and is located above the screen 33 for puncturing the ton bags containing the high modulus agent or lignin fiber.

[0035] In one embodiment, receiving grooves 34 are provided at the bottom of the inner wall of the upper frame plate 32 and the top of the inner wall of the lower frame plate 31. The screen 33 is clamped inside the upper frame plate 32 and the lower frame plate 31 through the receiving grooves 34. The screen 33 is woven by crisscrossing steel wires. The side length of the mesh holes of the screen 33 is set to 20 - 25 mm, which can prevent the high modulus agent or lignin fiber with larger particle sizes from falling into the hopper 2 and ensure the uniformity of the falling of the high modulus agent and lignin fiber. Locking buttons 35 are installed on the sides of the upper frame plate 32 and the lower frame plate 31 away from the hinges. The number of the locking buttons 35 is two and they are symmetrically distributed about the center of the side of the upper frame plate 32, so that the upper frame plate 32 can be opened at any time, and the staff can directly take out the screen 33 clamped by the upper frame plate 32 and the lower frame plate 31, making the maintenance or cleaning of the screen 33 more convenient and ensuring the good state of the screen 33.

[0036] In one embodiment, the breaking body 41 is composed of a rod body 411 located below the screen 33 and a conical body 412 located above the screen 33. The rod body 411 and the conical body 412 are integrally formed, which is convenient for the production and manufacturing of the breaking body 41. The breaking component 4 further includes a cross plate 42 connected to the bottom end of the rod body 411 and several baffle plates 43 disposed on the outer side of the rod body 411. The two ends of the cross plate 42 are connected to the left and right side walls of the hopper 2, which is convenient for the installation and use of the breaking body 41. The cross section of the baffle plate 43 is triangular, and several baffle plates 43 are evenly spaced along the outer surface of the rod body 411. The high modulus agent or lignin fiber falling into the hopper 2 can be divided into several regions, avoiding the accumulation of the high modulus agent or lignin fiber and reducing the occurrence of segregation phenomenon, thereby optimizing the fluidity of the high modulus agent or lignin fiber and helping to maintain the uniformity and quality stability of the material.

[0037] The implementation manner is specifically as follows: In road engineering, when producing the middle surface layer of the production road, the staff uses a forklift to lift the ton bag containing the high modulus agent above the hopper 2 and drop it onto the top of the screen 33. At this time, the ton bag will be punctured by the puncturing body 41, and the high modulus agent will automatically fall downward into the hopper 2. During this process, the screen 33 can screen the high modulus agent on its top to prevent the high modulus agent with larger particle size from falling into the hopper 2 due to moisture absorption and caking, thereby ensuring the uniformity and quality stability of the high modulus agent;

[0038] When producing the surface layer of the road, the ton bag containing the lignin fiber is lifted above the hopper 2. At this time, the ton bag will also be punctured by the puncturing body 41, and the lignin fiber will automatically fall downward into the hopper 2. The screen 33 will screen the lignin fiber on its top to prevent the lignin fiber with larger particle size from falling into the hopper 2 due to moisture absorption and caking, thereby ensuring the uniformity and quality stability of the lignin fiber;

[0039] And when the screen 33 is used for a long time, the staff can open the lock 35 on one side of the upper frame plate 32 and the lower frame plate 31, turn the upper frame plate 32 upward to open the upper frame plate 32. At this time, the staff can directly take out the screen 33 to clean or repair the screen 33, so as to ensure the good state of the screen 33, avoid blockage when the high modulus agent or lignin fiber falls, and improve the screening efficiency;

[0040] This implementation manner specifically solves the problem in the prior art that before using the high modulus agent and lignin fiber, they both need to be taken out of the ton bag and put into the asphalt mixture for uniform dispersion. However, the existing feeding devices for the high modulus agent or lignin fiber cannot control the particle size of the high modulus agent or lignin fiber. Some high modulus agents or lignin fibers with moisture absorption and caking are easily mixed in, resulting in unstable quality. Moreover, the high modulus agent or lignin fiber needs to be taken out of the ton bag and poured into the hopper 2, which consumes a lot of time and has low working efficiency.

[0041] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
