Description

Technical Field

[0001] This invention relates to the field of civil engineering equipment, and more specifically, to a belt conveyor for sorting various civil engineering materials. Background Technology

[0002] In the field of civil engineering, there are many types of civil engineering materials, such as steel used in construction, cement-mixed concrete and cement mortar, materials needed for masonry, waterproofing materials, special adhesives, wood materials, and decorative materials. However, regardless of the type, it is essential to ensure that the quality is not compromised to avoid affecting its use. Among these, the various sizes of sand and gravel in cement-mixed concrete and cement mortar need to be sorted out to obtain sand and gravel particles of the appropriate size before use, in order to meet the actual needs of the construction site. The sorted sand and gravel particles are then transported to the designated location using a belt conveyor.

[0003] Currently, in the process of transporting sand and gravel using belt conveyors, the sand and gravel contains large particles, small particles, and soil, which need to be sorted. However, the screening equipment used for sand and gravel screening only performs simple screening of the sand and gravel particles, which has certain limitations in practical applications. For example, the raw sand and gravel materials need to be loaded onto the screening equipment, screened, and then collected separately. Then, other handling equipment is used to transport the screened materials in batches. This operation process is not only cumbersome and time-consuming, but also seriously reduces the efficiency of civil construction. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a belt conveyor for sorting various civil engineering materials.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A multi-construction material sorting belt conveyor includes an H-shaped plate, with support feet fixedly connected to the four bottom corners of the H-shaped plate.

The other end of the support rod is rotatably connected to the inside of the U-shaped frame. Multiple filter holes are opened on the surface of both the first filter plate and the second filter plate.

[0009] Furthermore, a cleaning assembly is provided above the first filter plate and the second filter plate. The cleaning assembly includes a plurality of second hydraulic rods fixedly connected to the bottom of the H-shaped plate. One end of each second hydraulic rod is fixedly connected to a fixing plate, and a shaped cleaning brush is fixedly connected to each second hydraulic rod through the fixing plate.

[0010] Furthermore, the pallet is located inside the main conveyor belt and is used to support the main conveyor belt. Square slots are provided on both sides inside the pallet, and a screen plate is fixedly connected inside the square slot. Extension plates are fixedly connected to both ends of one side of the pallet, and a conveying assembly is provided directly below the screen plate.

[0011] Furthermore, the conveying assembly includes a first rotating rod and a second rotating rod rotatably connected to both ends of the inner side of the upright plate. Both ends of the first rotating rod and the second rotating rod are rotatably connected to a transmission assembly. The first rotating rod and the second rotating rod are rotatably connected to the drive rod of the drive motor through the transmission assembly. The outer circular surfaces of the first rotating rod and the second rotating rod are rotatably connected to a driven conveyor belt.

[0012] Furthermore, the upper surface of the sieve plate is provided with a guiding mechanism, which includes a plurality of second support plates fixedly connected to the top inner side of the upright plate. A second upright is fixedly connected to one end of the bottom of the second support plate, and a guide plate is rotatably connected to the outer surface of the second upright. A fixed frame is fixedly connected to the top of the guide plate, and a first adjusting plate is rotatably connected inside the fixed frame. A first sliding seat is rotatably connected to one end of the first adjusting plate, and a driving mechanism is movably connected to the first adjusting plate through the first sliding seat.

[0013] Furthermore, the driving mechanism includes a first support plate fixedly connected to the top of the inner plate, a servo motor fixedly connected to one side of the outer surface of the first support plate, a threaded rod fixedly connected to the output end of the servo motor, a first limiting rod fixedly connected to one end of the outer side of the first support plate, and a first sliding seat that meshes with the threaded rod slidably connected to the outer circular surface of the first limiting rod.

[0014] Furthermore, a toggle mechanism is provided at one end of the upper surface of the screen plate. The toggle mechanism includes a third support plate fixedly connected to both ends of the inner side of the vertical plate. A lead screw is rotatably connected to one end of the inner side of the third support plate. A second limiting rod is fixedly connected to one side of the outer surface of the third support plate. A second fixed wheel is fixedly connected to one end of the lead screw. A belt is rotatably connected to the outer surface of the second fixed wheel. A first fixed wheel is rotatably connected to the second fixed wheel through the belt. The first fixed wheel is fixedly connected to the threaded rod.

[0015] Furthermore, the outer circular surface of the second limiting rod is slidably connected to a second sliding seat that meshes with the lead screw, and a scraper is fixedly connected to the bottom of the second sliding seat.

[0016] Furthermore, the surface of the sieve plate is provided with a plurality of sieve holes, and the diameter of the sieve holes of the sieve plate is larger than that of the filter holes of the first filter plate and the second filter plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) This scheme is equipped with a sorting mechanism and a main conveyor belt. When the main conveyor belt is used to transport sand and gravel, large sand and gravel particles can be intercepted by the combined action of the first and second filter plates. At the same time, the fine sand entrained in the sand and gravel particles can be screened and separated through its filter holes. The screened fine sand is directly transported to the designated location by the main conveyor belt. In this process, not only is the screening problem of sand and gravel particles solved, but the efficiency of transportation is also guaranteed, thereby improving the efficiency of the entire civil construction process.

[0019] (2) By setting up H-shaped plates and cleaning components, during the long-term screening of civil engineering materials using the first and second filter plates, the filter holes of the first and second filter plates are easily blocked, which seriously affects the filtration effect of fine sand. At this time, the second hydraulic rod can be activated to lower the irregular cleaning brush and clean the filter holes of the first and second filter plates, thereby ensuring that the screening of sand and gravel particles can be carried out normally and avoiding the situation where the filter holes are blocked and the filtration of fine sand is affected.

[0020] (3) By setting up a sorting mechanism and a sieve plate, after the fine sand entrained in the sand and gravel particles is separated by the first filter plate and the second filter plate, the sand and gravel piled up in the groove formed by the first filter plate and the second filter plate can be activated again to make it extend, so that the first filter plate and the second filter plate form a reverse fold. At this time, the sand and gravel can fall onto the sieve plate through the inclined surface of the first filter plate and the second filter plate, and after secondary screening by the sieve plate, the smaller sand and gravel fall from the sieve hole onto the driven conveyor belt and are transported to the appropriate position. In this process, the further screening of sand and gravel particles is completed, thereby improving the sorting effect of civil engineering materials. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 6 A multi-construction material sorting belt conveyor includes an H-shaped plate 1, with support feet 2 fixedly connected to the four corners of the bottom of the H-shaped plate 1. An upright plate 3 is fixedly connected to the H-shaped plate 1 via the support feet 2. A support plate 4 is fixedly connected to the inner side of the upright plate 3. Screen plates 7 are provided on both sides inside the support plate 4. A drive motor 5 is fixedly connected to one end of the outer side of the upright plate 3. A drive rod is fixedly connected to the output end of the drive motor 5. An auxiliary rod 51 is rotatably connected to one end of the inner side wall of the upright plate 3. A main conveyor belt 6 is rotatably connected to the middle of the outer circular surfaces of the auxiliary rod 51 and the drive rod. A sorting mechanism 9 is provided on the upper surface of the main conveyor belt 6.

[0038] The sorting mechanism 9 includes multiple connecting plates 91 fixedly connected to the middle of the bottom of the H-shaped plate 1. A first hydraulic rod 92 is fixedly connected to the bottom end of one side of the outer surface of the connecting plate 91. Multiple first uprights 96 are fixedly connected to the middle of the bottom of the H-shaped plate 1. A first filter plate 97 and a second filter plate 98 are rotatably connected to the bottom of the outer circular surface of the multiple first uprights 96.

[0039] like Figure 1 , Figure 3 , Figure 4As shown, a U-shaped frame 95 is fixedly connected to one end of the top of the first filter plate 97 and the second filter plate 98. A support rod 94 is rotatably connected inside the U-shaped frame 95. A support base 93 is fixedly connected to one end of the first hydraulic rod 92. One end of the support rod 94 is rotatably connected to the inside of the support base 93, and the other end of the support rod 94 is rotatably connected to the inside of the U-shaped frame 95. Multiple filter holes are opened on the surface of the first filter plate 97 and the second filter plate 98.

[0040] The sand and gravel are poured onto the main conveyor belt 6, and the drive motor 5 is started, causing the drive rod to rotate. This causes the main conveyor belt 6 to rotate on the drive rod and auxiliary rod 51, thus conveying the sand and gravel. At this time, the first hydraulic rod 92 is activated, causing it to retract. This causes the support seat 93 to move the support rod 94 backward, and the first filter plate 97 and the second filter plate 98 to fold, forming a groove. The sand and gravel particles conveyed by the main conveyor belt 6 reach the groove formed by the first filter plate 97 and the second filter plate 98. Large sand and gravel particles are intercepted by the combined action of the first filter plate 97 and the second filter plate 98, while fine sand entrained in the sand and gravel particles can pass through. The filter holes are screened and separated, and the screened fine sand is directly transported to the designated location via the main conveyor belt 6. In this process, not only is the screening problem of sand and gravel solved, but the efficiency of conveying is also guaranteed, thereby improving the efficiency of the entire civil construction process. After the fine sand in the sand and gravel is sorted, the first hydraulic rod 92 can be activated again to extend it, so that the support seat 93 drives the support rod 94 to move forward, and the first filter plate 97 and the second filter plate 98 are folded in opposite directions, so that the sorted sand and gravel fall onto the screen plates 7 on both sides of the pallet 4 along the first filter plate 97 and the second filter plate 98, which makes it convenient for the staff to further sort the sand and gravel on the screen plates 7.

[0041] like Figure 1 , Figure 3 , Figure 4 As shown, a cleaning assembly 10 is provided above the first filter plate 97 and the second filter plate 98. The cleaning assembly 10 includes a plurality of second hydraulic rods 101 fixedly connected to the bottom of the H-shaped plate 1. One end of the second hydraulic rod 101 is fixedly connected to a fixing plate 102, and the second hydraulic rod 101 is fixedly connected to a shaped cleaning brush 103 through the fixing plate 102.

[0042] During the long-term screening of civil engineering materials using the first filter plate 97 and the second filter plate 98, the filter holes of the first filter plate 97 and the second filter plate 98 are easily blocked, which seriously affects the filtration effect of fine sand. At this time, the second hydraulic rod 101 can be activated to extend it, thereby causing the irregular cleaning brush 103 to descend and use the irregular cleaning brush 103 to clean the filter holes of the first filter plate 97 and the second filter plate 98. This ensures that the screening of sand and gravel particles can be carried out normally and avoids the situation where the filter holes are blocked, which affects the filtration of fine sand.

[0043] like Figure 1 , Figure 2 , Figure 5 As shown, the pallet 4 is located inside the main conveyor belt 6 and is used to support the main conveyor belt 6. Square slots are opened on both sides inside the pallet 4. A screen plate 7 is fixedly connected inside the square slot. Extension plates 8 are fixedly connected to both ends of one side of the pallet 4. A conveying assembly 15 is arranged directly below the screen plate 7.

[0044] like Figure 1 , Figure 2 , Figure 5 As shown, the conveying assembly 15 includes a first rotating rod 151 and a second rotating rod 152 rotatably connected to the two ends of the inner side of the upright plate 3. Both ends of the first rotating rod 151 and the second rotating rod 152 are rotatably connected to a transmission assembly 14. The first rotating rod 151 and the second rotating rod 152 are rotatably connected to the drive rod of the drive motor 5 through the transmission assembly 14. The outer circular surfaces of the first rotating rod 151 and the second rotating rod 152 are rotatably connected to a driven conveyor belt 153.

[0045] After the fine sand entrained in the aggregate particles is separated using the first filter plate 97 and the second filter plate 98, the aggregate piled up in the groove formed by the first filter plate 97 and the second filter plate 98 can easily affect the subsequent sorting effect of new aggregate. At this time, the movement of the main conveyor belt 6 can be stopped, and the first hydraulic rod 92 can be activated to extend it, thereby causing the first filter plate 97 and the second filter plate 98 to rotate in opposite directions simultaneously, forming a reverse folding shape. This allows the aggregate to fall onto the screen plate 7 through the inclined surfaces of the first filter plate 97 and the second filter plate 98, and undergo secondary screening by the screen plate 7. After the smaller sand and gravel fall from the screen holes onto the driven conveyor belt 153, the drive motor 5 is restarted, causing the main conveyor belt 6 to move. At the same time, with the cooperation of the transmission assembly 14 (which includes a first pulley fixedly connected to the auxiliary rod 51 and a second pulley fixedly connected to both ends of the second rotating rod 152, and the first and second pulleys are connected by a transmission belt), the driven conveyor belt 153 rotates, transporting the small sand and gravel particles on its upper surface to the appropriate position. In this process, not only is further screening of the sand and gravel particles completed, but the sorting effect of civil engineering materials is also improved.

[0046] like Figure 1 , Figure 5 , Figure 6 As shown, a guide mechanism 12 is provided on the upper surface of the sieve plate 7. The guide mechanism 12 includes a plurality of second support plates 121 fixedly connected to the top inner side of the vertical plate 3. A second vertical rod 122 is fixedly connected to one end of the bottom of the second support plate 121. A guide plate 123 is rotatably connected to the outer surface of the second vertical rod 122. A fixing frame 124 is fixedly connected to the top of the guide plate 123. A first adjusting plate 126 is rotatably connected inside the fixing frame 124. A first sliding seat 125 is rotatably connected to one end of the first adjusting plate 126. A drive mechanism 11 is movably connected to the first adjusting plate 126 through the first sliding seat 125.

[0047] When conveying sand and gravel from the main conveyor belt 6 to the screen plate 7, the drive mechanism 11 can be activated to move the first sliding seat 125 forward, and the first adjusting plate 126 can be used to make the guide plate 123 rotate clockwise on the second upright 122. This allows the guide plate 123 to be supported on the lower side of the second filter plate 98, so that the sand and gravel on the second filter plate 98 are conveyed to the screen plate 7 through the inclined surfaces of the second filter plate 98 and the guide plate 123 for further screening. This process avoids the situation where a small amount of sand and gravel remains on the main conveyor belt 6, affecting the subsequent sorting operation of the sand and gravel.

[0048] like Figure 1 , Figure 5 , Figure 6As shown, the drive mechanism 11 includes a first support plate 111 fixedly connected to the top of the inner end of the upright plate 3. A servo motor 112 is fixedly connected to one side of the outer surface of the first support plate 111. A threaded rod 113 is fixedly connected to the output end of the servo motor 112. A first limiting rod 114 is fixedly connected to one end of the outer side of the first support plate 111. A first sliding seat 125 that meshes with the threaded rod 113 is slidably connected to the outer circular surface of the first limiting rod 114.

[0049] After the guide plate 123 guides the sand and gravel on the main conveyor belt 6, the servo motor 112 can be started to rotate the threaded rod 113. Under the action of the first limit rod 114, the first sliding seat 125 slides backward on the first limit rod 114, thereby causing the first adjusting plate 126 to drive the guide plate 123 to rotate counterclockwise. This allows the sand and gravel piled on one side of the screen plate 7 to be spread out on the screen plate 7. This operation process avoids the situation where a small amount of small sand and gravel is piled up on the large sand and gravel and is not screened.

[0050] like Figure 1 , Figure 5 , Figure 6 As shown, a toggle mechanism 13 is provided at one end of the upper surface of the sieve plate 7. The toggle mechanism 13 includes a third support plate 131 fixedly connected to both ends of the inner side of the vertical plate 3. A lead screw 132 is rotatably connected to one end of the inner side of the third support plate 131. A second limiting rod 133 is fixedly connected to one side of the outer surface of the third support plate 131. A second fixed wheel 136 is fixedly connected to one end of the lead screw 132. A belt 135 is rotatably connected to the outer surface of the second fixed wheel 136. A first fixed wheel 134 is rotatably connected to the second fixed wheel 136 through the belt 135. The first fixed wheel 134 is fixedly connected to the threaded rod 113.

[0051] like Figure 1 , Figure 5 , Figure 6 As shown, the outer circular surface of the second limiting rod 133 is slidably connected to a second sliding seat 137 that meshes with the lead screw 132, and a scraper 138 is fixedly connected to the bottom of the second sliding seat 137.

[0052] like Figure 1 , Figure 5 As shown, the surface of the sieve plate 7 is provided with multiple sieve holes, and the diameter of the sieve holes of the sieve plate 7 is larger than that of the filter holes of the first filter plate 97 and the second filter plate 98.

[0053] During the process of spreading the sand and gravel on the screen plate 7, the threaded rod 113 can drive the first fixed wheel 134 to rotate, and the belt 135 can drive the second fixed wheel 136 to rotate synchronously. At the same time, since the thread of the lead screw 132 is opposite to the thread direction of the thread of the lead screw 113, the lead screw 132 rotates synchronously during the rotation of the lead screw 113. Under the action of the second limit rod 133, the second sliding seat 137 moves forward, thereby causing the scraper 138 to move forward synchronously. The scraper 138 is used to make the large sand and gravel particles left on the screen plate 7 fall off the extension plate 8 and be collected by the external collection box.

[0054] Instructions for use: Pour the sand and gravel onto the main conveyor belt 6 and start the drive motor 5, causing the drive rod to rotate. This causes the main conveyor belt 6 to rotate on the drive rod and auxiliary rod 51, conveying the sand and gravel. At this time, activate the first hydraulic rod 92, causing it to retract. This causes the support seat 93 to move the support rod 94 backward, folding the first filter plate 97 and the second filter plate 98 and forming a groove. The sand and gravel particles conveyed by the main conveyor belt 6 reach the groove formed by the first filter plate 97 and the second filter plate 98, where large sand and gravel particles are intercepted by the combined action of the first filter plate 97 and the second filter plate 98. Simultaneously, fine sand entrained in the sand and gravel particles can be screened and separated through its filter holes. The screened fine sand is directly transported to the designated location via the main conveyor belt 6. During the long-term screening of civil engineering materials using the first filter plate 97 and the second filter plate 98, the second hydraulic rod 101 can be activated to extend it, thereby causing the irregular cleaning brush 103 to descend. The irregular cleaning brush 103 is then used to clean the filter holes of the first filter plate 97 and the second filter plate 98, ensuring that the screening of sand and gravel particles can proceed normally. After the fine sand entrained in the sand and gravel particles is separated using the first filter plate 97 and the second filter plate 98, the screen can be activated... The first hydraulic rod 92 is extended, causing the first filter plate 97 and the second filter plate 98 to rotate simultaneously in opposite directions, forming a reverse fold. This causes sand and gravel to fall from the inclined surfaces of the first filter plate 97 and the second filter plate 98 onto the screen plate 7, where they undergo secondary screening. After the guide plate 123 guides the sand and gravel on the main conveyor belt 6, the servo motor 112 can be activated to rotate the threaded rod 113. Under the action of the first limit rod 114, the first sliding seat 125 slides backward on the first limit rod 114, causing the first adjusting plate 126 to drive the guide plate 123 to rotate counterclockwise. The movement causes the sand and gravel accumulated on one side of the screen plate 7 to be spread out on the screen plate 7. The first fixed wheel 134 is driven to rotate by the threaded rod 113, and the second fixed wheel 136 is driven to rotate synchronously by the belt 135. At the same time, since the thread of the lead screw 132 is opposite to the thread direction of the thread of the lead screw 113, the lead screw 132 rotates synchronously during the rotation of the lead screw 113. Under the action of the second limit rod 133, the second sliding seat 137 moves forward, thereby causing the scraper 138 to move forward synchronously. The scraper 138 causes the large sand and gravel particles left on the screen plate 7 to fall off the extension plate 8 and be collected by the external collection box.
