Description

Technical Field

[0001] This utility model relates to the field of construction waste discharge, and in particular to the intelligent adjustable feed channel applied to a 3D drum screen for construction waste. Background Technology

[0002] Construction waste needs to be screened into different particle sizes through a 3D drum screen before undergoing secondary processing. Construction waste is usually fed into the 3D drum screen through a feeding channel. A discharge hopper is usually installed above the construction waste discharge point in the feeding channel. The construction waste falls into the feeding channel through the periodic opening and closing of the discharge hopper. Therefore, construction waste is often fed into the 3D drum screen in piles through the feeding channel. When the pile of waste is too high, it often collapses during the inclined ascent, causing the construction waste to roll back to the initial feeding position of the feeding channel.

[0003] In the existing technology, a feeder is installed at the bottom of the unloading hopper. The function of the feeder is to spread the construction waste on the feeding channel. The feeder solution is costly and the feeder maintenance cost is also high.

[0004] In summary, while reducing equipment costs, how to prevent waste from rolling down the feed channel has become an urgent problem for researchers in this field. Utility Model Content

[0005] The technical problem to be solved by this utility model is: how to prevent garbage from rolling down the feed channel while reducing equipment costs;

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] This utility model relates to an intelligent adjustable feeding channel for a 3D drum screen for construction waste, comprising: a frame having a first horizontal section, an inclined section, and a second horizontal section interconnected, the second horizontal section being higher than the first horizontal section; a drive roller, rotatably mounted above the end of the second horizontal section via a second support frame, and located above the inlet of the drum screen; a driven roller, rotatably mounted above the end of the first horizontal section via a first support frame; a first reversing roller, rotatably mounted above the connection between the inclined section and the second horizontal section via a second support frame; and a second reversing roller, rotatably mounted above the connection between the inclined section and the second horizontal section via a first support frame. The frame is rotatably mounted above the connection between the inclined section and the first horizontal section; a conveyor belt is wound between the driving roller and the driven roller, with the first reversing roller abutting against the lower bottom surface of the conveyor belt and the second reversing roller abutting against the upper bottom surface of the conveyor belt; two pressure rollers are mounted above the connection between the first horizontal section and the inclined section via the first support frame and are located on the left and right sides of the conveyor belt conveying surface, adapted to abut against the upper surface of the conveyor belt conveying surface; a discharge hopper is mounted above the first horizontal section; and a flattening roller connects the two pressure rollers and has a material passage gap between itself and the conveyor belt.

[0008] Furthermore, multiple first support wheel sets are provided on the first support frame of the first horizontal section and the second support frame of the second horizontal section. Each first support wheel set includes two first support seats arranged opposite each other. A first support roller is rotatably connected between the two first support seats. The axis of the first support roller is parallel to the axis of the driven roller. The top of the first support roller abuts against the lower surface of the top of the conveyor belt for support.

[0009] Furthermore, the top of the second support frame of the inclined section is provided with a plurality of third support wheel sets, the third support wheel sets including: two outer support seats arranged opposite each other, the bottom of which are fixedly connected to the second support frame; two inner support seats, which are arranged between the two outer support seats; two inclined support rollers, which are rotatably arranged between the corresponding inner support seats and outer support seats; and a horizontal support roller, which is rotatably arranged between the two inner support seats; the lower surface of the conveyor belt is supported on the two inclined support rollers and the horizontal support roller.

[0010] Furthermore, the bottom of the inclined section is provided with a plurality of second support wheel sets, the second support wheel sets including: a third support seat arranged opposite to each other, and a third support roller rotatably connected between the two third support seats; the bottom surface of the conveyor belt is supported on the third support roller.

[0011] Furthermore, a first encoder is provided on one side of the drive roller, which is used to obtain the number of rotations of the drive roller; a second encoder is provided on one side of the driven roller, which is used to obtain the number of rotations of the driven roller; a linear module is provided on the first horizontal section, and the movable end of the linear module is connected to the first support frame; when the value obtained by the second encoder is less than the value obtained by the first encoder, the linear module drives the first support frame to move away from the second support frame, thereby tensioning the conveyor belt between the drive roller and the driven roller.

The flat roller is connected to two pressure rollers, and there is a material passage gap between it and the conveyor belt.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] To address the issue that construction waste may roll back to the initial feeding position of the infeed channel due to excessive accumulation during the inclined ascent process, thus affecting the subsequent unloading of construction waste, this solution provides the following implementation example.

[0020] like Figure 1 As shown, this embodiment describes an intelligent adjustable feed channel applied to a 3D drum screen for construction waste, comprising:

[0021] The frame 1 has a first horizontal section 11, an inclined section 12, and a second horizontal section 13 that are connected to each other. The left end of the first horizontal section 11 is connected to the right end of the inclined section 12. The inclined section 12 extends obliquely to the upper right and its left end is connected to the right end of the second horizontal section 13. The overall frame 1 has a stepped structure with the left side higher than the right side. The conveyor belt 2 also has a structure with the left side higher than the right side.

[0022] The drive roller 3 is rotatably mounted above the end of the second horizontal section 13 via the second support frame 42 and is located above the inlet of the drum screen 5. The second horizontal section 13 is provided with the second support frame 42, and the drive roller 3 is rotatably mounted on the second support frame 42. The drive roller 3 is an electric roller. As long as the drive roller 3 is powered, it will rotate. The drive roller 3 provides power for the rotation of the conveyor belt 2.

[0023] The driven roller 6 is rotatably mounted above the end of the first horizontal section 11 via the first support frame 41, and the driven roller 6 is free to rotate at the right end of the first horizontal section 11;

[0024] The first reversing roller 7 is rotatably mounted above the connection between the inclined section 12 and the second horizontal section 13 via the second support frame 42. The second support frame 42 is mounted on the second horizontal section 13 and the inclined section 12. The first reversing roller 7 is rotatably mounted at the second support frame 42 located at the inclined section 12 and the second horizontal section 13. The bottom surface of the conveyor belt 2 contacts the top of the first reversing roller 7, thus realizing the transition of the conveyor belt 2 from a horizontal state to an inclined state.

[0025] The second reversing roller 8 is rotatably mounted above the connection between the inclined section 12 and the first horizontal section 11 via the first support frame 41. The first support frame 41 is mounted on the first horizontal section 11, and the second reversing roller 8 is mounted on the first support frame 41. The bottom upper surface of the conveyor belt 2 contacts the bottom of the second reversing roller 8, thereby realizing the transition of the conveyor belt 2 from an inclined state to a horizontal state.

[0026] The conveyor belt 2 is wound between the driving roller 3 and the driven roller 6. The first reversing roller 7 abuts against the bottom lower surface of the conveyor belt 2, and the second reversing roller 8 abuts against the bottom upper surface of the conveyor belt 2.

[0027] Two pressure rollers 9 are mounted above the connection between the first horizontal section 11 and the inclined section 12 via a first support frame 41, and are located on the left and right sides of the conveyor surface of the conveyor belt 2. They are adapted to abut against the upper surface of the conveyor surface of the conveyor belt 2. When the conveyor belt 2 needs to change from a horizontal state to an inclined state, the pressure rollers 9 abut against the left and right sides of the conveyor belt 2, pressing the conveyor belt 2 down. In this way, the left side of the conveyor belt 2 is in an inclined state and the right side is in a horizontal state.

[0028] The unloading hopper 14 is located above the first horizontal section 11. When construction waste is unloaded, the waste falls onto the conveyor belt at the first horizontal section 11.

[0029] like Figure 2 As shown, the flattening roller 10 connects the two pressure rollers 9 and has a material passage gap 100 between it and the conveyor belt 2. In this way, excessively tall construction waste will pass through the material passage gap 100 between the flattening roller 10 and the conveyor belt 2 to flatten the construction waste, preventing it from rolling down when passing over the inclined conveyor belt 2. Compared with the traditional solution of adding a feeder, this device can achieve the flattening of construction waste on the feed channel by using a flattening roller 10, while reducing production costs.

[0030] like Figure 4 As shown, in some possible embodiments, a plurality of first support wheel sets are provided on the first support frame 41 of the first horizontal section 11 and the second support frame 42 of the second horizontal section 13. The first support wheel set includes two first support seats 21 arranged opposite to each other. A first support roller 22 is rotatably connected between the two first support seats 21. The axis of the first support roller 21 is parallel to the axis of the driven roller 6. The top of the first support roller 21 abuts against the lower surface of the top of the conveyor belt 2 for support.

[0031] In this embodiment, multiple first support wheel sets are used to support the conveyor belt 2 in a horizontal state, that is, to support the conveyor belt 2 located at the first horizontal section 11 and the conveyor belt 2 located at the second horizontal section 13, so as to realize the smooth falling and discharge of waste on the conveyor belt 2. The first support wheel set includes first support seats 21 arranged on the left and right, and first support rollers 22 rotatably located between the two first support seats 21. The top lower surface of the conveyor belt 2 is supported on the first support rollers 22.

[0032] like Figure 3 As shown, in some possible embodiments, the top of the second support frame 42 of the inclined section 12 is provided with a plurality of second support wheel sets. The second support wheel sets include: two outer support seats 31 disposed opposite to each other, the bottom of which is fixedly connected to the second support frame 42; two inner support seats 32 disposed between the two outer support seats 31; two inclined support rollers 33 rotatably disposed between the corresponding inner support seats 32 and outer support seats 31; and a horizontal support roller 34 rotatably disposed between the two inner support seats 32. The lower surface of the conveyor belt 2 is supported on the two inclined support rollers 33 and the horizontal support roller 34.

[0033] In this embodiment, two outer support seats 31 are arranged on the left and right sides of the second support frame 42, and two inner support seats 32 are also arranged on the second support frame and located between the two outer support seats 31. An inclined support roller 33 is rotatably arranged between the outer support seats 31 and the inner support seats 32. A horizontal support roller 34 is rotatably arranged between the two inner support seats 32. The lower surface of the conveyor belt 2 is in contact with the two inclined support rollers 33 and the horizontal support roller 34. Thus, the conveyor belt 2 located at the inclined section 12 has a structure that is low in the middle and high on both sides, which can prevent garbage from falling from the left and right sides of the conveyor belt 2.

[0034] like Figure 2 As shown, in some possible embodiments, the bottom of the inclined section 12 is provided with a plurality of third support wheel sets, the third support wheel sets including: third support seats 51 disposed opposite to each other, and a third support roller 52 rotatably connected between the two third support seats 51; the bottom surface of the conveyor belt 2 is supported on the third support roller 51.

[0035] The function of the third support wheel set is to support the bottom of the conveyor belt 2 located at the inclined section 12, so as to prevent the bottom of the conveyor belt 2 from being stretched due to its own weight. The third support wheel set includes two third support seats 51 arranged opposite to each other, and a third support roller 52 rotatably connected between the two third support seats 51. The third support roller 52 supports the lower surface of the bottom of the conveyor belt 2, so as to prevent the conveyor belt 2 from being stretched due to its own weight.

[0036] See Figure 1 A first encoder 31 is provided on the outer side of the drive roller 3, and a second encoder 61 is provided on the outer side of the driven roller 6. The first encoder 31 is used to obtain the number of rotations of the drive roller 3, and the second encoder 61 is used to obtain the number of rotations of the driven roller 6. When the conveyor belt 2 is tensioned between the driven roller 6 and the drive roller 3, the values ​​obtained by the first encoder 31 and the second encoder 61 are the same. When the value obtained by the second encoder 61 is less than the value obtained by the first encoder 31, the linear module 01 drives the first support frame 41 to move to the right. At this time, the first support frame 41 drives the driven roller to move to the right, and re-tensions the conveyor belt 2 between the driven roller 6 and the drive roller 3.

[0037] It should be noted that the linear module 01 can be implemented by directly driving the first support frame 41 with an electric cylinder or a pneumatic cylinder, or by using a motor and a lead screw pair to achieve the left and right linear movement of the first support frame 41.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
