Description

TECHNICAL FIELD

[0001] The present application relates to the field of backfill, in particular to a regenerated backfill production equipment. BACKGROUND

[0002] Backfill refers to the soil returned and filled after the completion of the underground engineering such as foundation in the construction, which can be used for civil buildings, large foundation pits and trench backfilling.

[0003] With the continuous development of urbanization, the amount of construction waste gradually increases, and the reuse of construction waste gradually attracts people's attention; therefore, the backfill used for building foundation pit and trench backfilling can be made of construction waste.

[0004] Currently, when preparing backfill from construction waste, the construction waste needs to be crushed and ground, and then sieved according to the diameter of the crushed construction waste to obtain construction waste particles of different diameters. Then, the construction waste particles of different diameters are transported to different areas for different purposes. Among them, the part suitable for backfill is transported to the next process, and the construction waste particles suitable for backfill are mixed with cement, water, early strength agent and the like according to a certain proportion and stirred uniformly to prepare backfill.

[0005] However, because the construction waste is placed on the ground, the excavator needs to be assisted when the construction waste is put into the crusher. If the working site is too limited and the excavator cannot enter the working site, it will be difficult to carry out the work. At the same time, the operation of the excavator to transport the construction waste will also generate a certain labor cost. Or if the construction waste is a certain distance away from the crusher, manual transportation of the construction waste back and forth is also needed, which causes waste of labor cost. SUMMARY

DETAILED DESCRIPTION

[0041] The following will be described in detail with reference to the accompanying drawings. Figures 1-7 The application is further described in detail.

[0042] The embodiments of the application disclose a regenerated backfill production equipment. Referring to Figure 1 The regenerated backfill production equipment comprises a feeding device 1, a crusher 2, a grinder 3, a screening machine 4 and a mixer 5 connected in sequence. The crusher 2, the grinder 3, the screening machine 4 and the mixer 5 are consistent with the existing regenerated backfill production equipment, and the feeding device 1 can also be directly connected with the existing regenerated backfill production equipment, and is used for automatically conveying the construction waste on the ground into the crusher 2.

[0043] Referring to Figure 1 and Figure 2 The feeding device 1 comprises a limiting frame 6 in the shape of a frame in cross section, a conveying mechanism 7 connected to one end of the limiting frame 6 and a pushing device 8 mounted on the limiting frame 6 and used for conveying the construction waste in the limiting frame 6 to the conveying mechanism 7. One end of the conveying mechanism 7 away from the limiting frame 6 can extend to the feeding port of the crusher 2, and the pushing device 8 and the conveying mechanism 7 are respectively located at the opposite two ends of the limiting frame 6, so that the pushing device 8 can push the material in the direction away from the pushing device 8, and at this time, the material will reach the conveying mechanism 7 and be conveyed to the crusher 2 by the conveying mechanism 7.

[0044] Referring to Figure 2The limiting frame 6 comprises two oppositely arranged mounting plates 61 and two folding telescopic plates 62 fixed between the two mounting plates 61, and the two folding telescopic plates 62 are respectively located at two ends of the two mounting plates 61, so that the two folding telescopic plates 62 and the two mounting plates 61 form a quadrilateral structure in space. The pushing device 8 and the conveying mechanism 7 can be respectively mounted on the two mounting plates 61 or respectively mounted on the two folding telescopic plates 62. The pushing device 8 is mounted on one mounting plate 61 and the conveying mechanism 7 is mounted on the other mounting plate 61 as an example for description.

[0045] The pushing device 8 comprises a push plate 81 slidingly connected in the limiting frame 6 and a linear driving member 82 for driving the push plate 81 to slide in the limiting frame 6, and the linear driving member 82 is fixed on the mounting plate 61. The linear driving member 82 can be selected from a gas cylinder, an electric push rod, etc. The gas cylinder is fixed on the mounting plate 61 and located on the side away from the other mounting plate 61, and the piston rod of the gas cylinder is fixed on the push plate 81. The push plate 81 can be driven to slide in the limiting frame 6 by the gas cylinder, so as to push the construction waste in the limiting frame 6 to the conveyor.

[0046] Referring to Figure 2 The mounting plate 61 comprises a first plate 611, a second plate 612 slidingly connected in the first plate 611, and an auxiliary plate 614 fixed perpendicularly on the side away from the first plate 611 and the second plate 612. The two folding telescopic plates 62 are respectively mounted on the two auxiliary plates 614, and the two auxiliary plates 614 form a mounting space 615 for mounting the push plate 81 with the first plate 611 and the second plate 612. Specifically, a second accommodating groove 613 is formed on the side of the first plate 611 facing the second plate 612 for embedding and sliding the second plate 612. By sliding the second plate 612 in the second accommodating groove 613, the length of the mounting plate 61 as a whole can be adjusted, so as to adjust the size of the limiting frame 6 to adapt to the needs of construction waste of different sizes.

[0047] The two pushing devices 8 are arranged in a group, one of the two pushing devices 8 in the same group is mounted on the first plate 611 and the other is mounted on the second plate 612, and the two pushing devices 8 are arranged on the same horizontal plane. The push plates 81 of the two pushing devices 8 in the same group are arranged in a staggered manner in the pushing direction of the linear driving member 82. In normal state, the second plate 612 extends out of the second accommodating groove 613, so that the mounting plate 61 is in the longest state. At this time, the opposite sides of the two push plates 81 in the same group are on the same vertical plane, so as to ensure the pushing of the construction waste. When the second plate 612 slides into the second accommodating groove 613, the two push plates 81 in the same group are close to each other, so that the opposite sides of the two push plates 81 overlap with each other and do not interfere with each other.

[0048] With reference to Figure 2 , the pushing device 8 can be provided with multiple groups in the height direction of the mounting plate 61, and the detection device 9 for detecting the height of the construction waste in the limiting frame 6 is also provided on the limiting frame 6, and the detection device 9 is connected with each group of pushing devices 8 through the controller. Specifically, the controller can be a PLC controller, and the detection device 9 can be a detection grating, or a detection camera, as long as it can detect the height of the construction waste in the limiting frame 6, and the application takes the detection grating as an example for description. The detection grating includes a transmitting end 91 and a receiving end 92, and the transmitting end 91 and the receiving end 92 are respectively installed on the opposite sides of the two folding telescopic plates 62. Under normal circumstances, the transmitting end 91 sends signals, and the receiving end 92 receives the signals sent by the transmitting end 91. The construction waste located in the limiting frame 6 will block the signals transmitted from the transmitting end 91 to the receiving end 92, and the height of the construction waste can be detected by checking the position of the signal received by the receiving end 92. The height of the construction waste detected by the detection device 9 controls the action of the pushing device 8 at different positions.

[0049] For example, when the height of the construction waste is lower than the highest point of the uppermost pushing plate 81 and lower than the lowest point of the uppermost pushing plate 81, the uppermost group of pushing devices 8 is started, so as to push the construction waste higher than the pushing plate 81 to the middle conveying mechanism 7. Then the detection device 9 detects that the construction waste is lower than the highest point of the second pushing plate 81 on the upper side and higher than the lowest point of the pushing plate 81, and simultaneously drives the two groups of pushing devices 8 on the upper side to start. In turn, the construction waste is pushed out from top to bottom.

[0050] With reference to Figure 2 and Figure 3 Each folding telescopic plate 62 includes a third plate 621 hinged to one of the mounting plates 61 and a fourth plate 622 hinged to the other mounting plate 61, and a first accommodating groove 623 is formed on the side of the third plate 621 facing the fourth plate 622 for embedding and sliding of the fourth plate 622. By operating the fourth plate 622 to slide in the first accommodating groove 623 of the third plate 621, the length of each folding telescopic plate 62 can be changed, so as to realize the adjustment of the size of the limiting frame 6. By adjusting the length of the two mounting plates 61 and the length of the two folding telescopic plates 62, the limiting frame 6 can be adjusted to any suitable size according to the size of the site, and the range of adaptation is wider.

[0051] With reference to Figures 3 to 5The sliding shaft 624 is fixed on the upper and lower sides of each fourth plate 622, and is located at one end of the fourth plate 622 close to the third plate 621. Two mounting ears 625 are fixed on the third plate 621 away from the other folding telescopic plate 62, and are located on the upper and lower sides of the third plate 621 and close to the fourth plate 622. Meanwhile, a sliding groove 626 is formed on the opposite sides of the first accommodating groove 623 for embedding and sliding of the sliding shaft 624. The sliding groove 626 includes a first groove 6261 formed on the third plate 621 and communicating with the first accommodating groove 623, and a second groove 6262 formed on the mounting ear 625 and vertically communicating with the end of the first groove 6261. Under normal circumstances, when the fourth plate 622 is operated to slide in the second accommodating groove 613, the sliding shaft 624 also slides in the first groove 6261. When the sliding shaft 624 slides to the communication position of the first groove 6261 and the second groove 6262 and slides into the second groove 6262, the fourth plate 622 is rotated about the axis of the sliding shaft 624 at this time, so that the fourth plate 622 is folded together with the third plate 621, which is convenient for storage when not in use.

[0052] Referring to Figure 4 In order to quickly and conveniently surround the construction waste with the limiting frame 6 during use, a quick assembly for detachable connection between the third plate 621 and the mounting plate 61 and / or between the fourth plate 622 and the mounting plate 61 can be provided. The present application takes the fourth plate 622 and the mounting plate 61 as an example for description.

[0053] The quick disassembly assembly 627 includes a mounting cylinder 6271 fixed on one side of the mounting plate 61 facing the fourth plate 622, and a hook 6272 integrally formed in an L shape fixed on one side of the fourth plate 622 facing the mounting plate 61. The quick disassembly assembly 627 is provided with two groups, and the two groups of quick disassembly assemblies 627 are respectively located at the two ends of the mounting plate 61, that is, the two mounting cylinders 6271 are respectively mounted on the first plate 611 and the second plate 612. A plurality of quick disassembly assemblies 627 form a group, and the plurality of quick disassembly assemblies 627 in the same group are spaced apart along the height direction of the mounting plate 61. Each hook 6272 forms an opening downward between the fourth plate 622. By hooking the hook 6272 on the fourth plate 622 in the mounting cylinder 6271, the mounting of the fourth plate 622 and the mounting plate 61 can be achieved. When disassembled, the hook 6272 can be directly disassembled from the mounting cylinder 6271, which is very convenient for mounting and dismounting.

[0054] It can be understood that the hook 6272 can also be mounted on the mounting plate 61, and the mounting cylinder 6271 is mounted on the fourth plate 622, as long as the detachable connection between the mounting plate 61 and the fourth plate 622 can be achieved.

[0055] Referring to Figure 4In order to avoid the material in the limiting frame 6 from leaking out from the quick release assembly 627, a shielding plate 6273 is fixed to the fourth plate 622 on the side facing the mounting plate 61 and located outside the quick release assembly 627. Normally, the side of the shielding plate 6273 away from the fourth plate 622 abuts against the mounting plate 61, and when the fourth plate 622 is folded to rotate relative to the mounting plate 61, the fourth plate 622 will also rotate the shielding plate 6273.

[0056] It can be understood that, in order to ensure that the fourth plate 622 can smoothly rotate the shielding plate 6273, the side of the shielding plate 6273 away from the fourth plate 622 is rounded, so that the shielding plate 6273 is in line contact with the mounting plate 61.

[0057] Referring to Figure 1 and Figure 5 , in order to ensure the stability of the limiting frame 6 in use, a fixing member 63 is arranged between the first plate 611 and the second plate 612 and between the third plate 621 and the fourth plate 622 to fix the relative positions of the two, the fixing member 63 between the first plate 611 and the second plate 612 is identical in structure to the fixing member 63 between the third plate 621 and the fourth plate 622, the only difference is the different installation position, and the fixing member 63 arranged between the third plate 621 and the fourth plate 622 is taken as an example for description.

[0058] The fixing member 63 includes a fixing bolt 631 screwed on the third plate 621, the fixing bolt 631 is located on the side of the third plate 621 close to the fourth plate 622, and a plurality of fixing bolts 631 are arranged along the height direction of the third plate 621, the fixing bolt 631 is arranged in the second accommodating groove 613 and abuts against the fourth plate 622 in the second accommodating groove 613, and by tightening the fixing bolt 631, the position of the fourth plate 622 in the second accommodating groove 613 can be fixed, thereby fixing the positions of the third plate 621 and the fourth plate 622.

[0059] Referring to Figure 2 and Figure 6 , the conveying mechanism 7 is detachably connected with the mounting plate 61 away from the pushing device 8. The conveying mechanism 7 includes a screw conveyor 71, a first connecting member 72 detachably connected between two screw conveyors 71 perpendicular to the conveying direction, a second connecting member 73 detachably connected between two screw conveyors 71 arranged at an angle to the conveying direction, and a third connecting member 74 detachably connected between the limiting frame 6 and the screw conveyor 71.

[0060] The screw conveyor 71 comprises a closed conveying sleeve 711, a conveying motor 712 fixed to the closed end of the conveying sleeve 711, and a screw conveying shaft 713 fixed to the output shaft of the conveying motor 712. The output shaft of the conveying motor 712 is fixed to the screw conveying shaft 713 to drive the screw conveying shaft 713 to rotate. The open end of the conveying sleeve 711 is the feeding port, and a discharge pipe 714 is fixed to the side wall of the conveying sleeve 711 and communicates with the inside of the conveying sleeve 711. By starting the conveying motor 712, the material at the feeding port can be conveyed into the discharge pipe 714 through the conveying sleeve 711, achieving the conveying of the material.

[0061] With reference to Figure 6 The first connecting piece 72 comprises a first threaded cylinder 721 threadedly connected between the discharge pipe 714 and the conveying sleeve 711. When two screw conveyors 71 with perpendicular conveying directions need to be connected, the conveying sleeve 711 of one screw conveyor 71 is butted against the discharge pipe 714 of the previous screw conveyor 71, and then the first threaded cylinder 721 is sleeved on the conveying sleeve 711 and the discharge pipe 714, and the two are connected through the first threaded cylinder 721, achieving the connection of the two screw conveyors 71 with perpendicular conveying directions.

[0062] When the conveying sleeve 711 of the latter screw conveyor 71 is connected to the discharge pipe 714 of the previous screw conveyor 71 through the first threaded cylinder 721, the first threaded cylinder 721 can be sleeved on the conveying sleeve 711 first, and then rotated towards the discharge pipe 714 of the previous screw conveyor 71, so that the first threaded cylinder 721 is screwed on the discharge pipe 714 through one end and screwed on the conveying sleeve 711 through the other end, achieving the connection of the two. Of course, the two ends of the inner hole of the first threaded cylinder 721 can also be processed as right and left threads. When installing, the first threaded cylinder 721 is placed between the conveying sleeve 711 and the discharge pipe 714, and then the first threaded cylinder 721 is screwed, so that the two ends of the first threaded cylinder 721 are screwed on the conveying sleeve 711 and the discharge pipe 714 at the same time.

[0063] The second connecting piece 73 comprises a connecting cylinder 731 integrally arranged at an angle, and a second threaded cylinder 732 threadedly connected at both ends of the connecting cylinder 731. The connecting cylinder 731 comprises a first cylinder 7311 and a second cylinder 7312 fixed to one end of the first cylinder 7311. The first cylinder 7311 and the second cylinder 7312 can be flexibly connected, so that the angle between the first cylinder 7311 and the second cylinder 7312 can be adjusted. Of course, the first cylinder 7311 and the second cylinder 7312 can also be rigidly connected. At this time, a plurality of connecting cylinders 731 can be prepared in advance, and the connecting cylinder 731 with the appropriate angle can be selected for use according to the site conditions. The specific determination can be made as required, and the present application will not be described in more detail.

[0064] The second threaded cylinder 732 is identical to the first threaded cylinder 721 in structure and use principle, and the difference is only in the different installation position. When two screw conveyors 71 need to be arranged at an angle, the connecting cylinder 731 is placed between the discharge pipe 714 of the previous screw conveyor 71 and the feeding port of the subsequent screw conveyor 71, and then the second threaded cylinder 732 is screwed between the discharge pipe 714 and the first cylinder 7311, and the other second threaded cylinder 732 is screwed between the second cylinder 7312 and the conveying sleeve 711 of the subsequent screw conveyor 71, so that the connection of the adjacent two screw conveyors 71 can be realized.

[0065] With reference to Figure 2 A discharge pipe 67 is threadedly connected to one of the mounting plates 61 away from the pushing device 8, the discharge pipe 67 is located on the lower side of the mounting plate 61 and penetrates the mounting plate 61, and the end of the discharge pipe 67 located inside the limiting frame 6 is higher than the end of the discharge pipe 67 located outside the limiting frame 6, so that the construction waste inside the limiting frame 6 can automatically fall to the outside of the discharge pipe 67 under the action of gravity.

[0066] The end of the discharge pipe 67 located outside the limiting frame 6 is connected to the feeding port of the screw conveyor 71 through a third connecting piece 74, the structure and installation mode of the third connecting piece 74 are identical to those of the second connecting piece 73, and the difference is only in the different installation position, which will not be repeated here.

[0067] With reference to Figure 7 Universal wheels 64 are installed on the lower side of the limiting frame 6, and when it is necessary to move the position of the limiting frame 6, the limiting frame 6 can be pushed to move through the universal wheels 64. Specifically, mounting grooves 65 for embedding the universal wheels 64 are formed on the lower side of each mounting plate 61 and folding and telescopic plate 62, and electric push rods 66 are fixedly connected to the closed ends of the mounting grooves 65, and the universal wheels 64 are installed on the push rods of the electric push rods 66, and the universal wheels 64 can be retracted into the mounting grooves 65 or extended from the mounting grooves 65 through the electric push rods 66. When it is necessary to move the position of the limiting frame 6, the universal wheels 64 can be extended from the mounting grooves 65 through the electric push rods 66, so that the limiting frame 6 can be pushed to move through the universal wheels 64. When the limiting frame 6 is wrapped around the construction waste, the electric push rods 66 can be operated to retract to drive the universal wheels 64 to embed into the mounting grooves 65, thereby increasing the stability of the limiting frame 6 when placed.

[0068] The implementation principle of the embodiment of the regenerated backfill soil production equipment is as follows: in use, the limiting frame 6 is directly surrounded around the construction waste, then the unloading pipe 67 and the screw conveyor 71 are connected together through the third connecting piece 74, and the plurality of screw conveyors 71 are connected through the first connecting piece 72 and the second connecting piece 73 according to the position of the crusher 2. After the power is turned on, the detection device 9 can detect the height of the construction waste, and the corresponding linear driving piece 82 is started according to the detection result to push the construction waste to the unloading pipe 67 through the push plate 81. The construction waste reaching the unloading pipe 67 falls from the unloading pipe 67 to the screw conveyor 71 outside the limiting frame 6 under the action of gravity, and the construction waste can be sequentially conveyed to the crusher 2 through each screw conveyor 71 to realize subsequent crushing and other work. The automatic feeding is realized, and the size of the limiting frame 6 can also be adjusted according to the site to adapt to the needs of various sites, reduce the influence of the site when the construction waste is carried, and reduce the waste of labor cost.

[0069] When the construction waste is carried, the hook 6272 is directly detached from the mounting cylinder 6271, the fourth plate 622 is folded on the third plate 621, and the second plate 612 is retracted into the second containing groove 613, so that the folding of the limiting frame 6 is realized.

[0070] The above are preferred embodiments of the present application, and are not limited to the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
