Description

Technical Field

[0001] The present invention relates to the technical field of concrete product production, and in particular to a material distribution system for automatic forming of concrete products. Background Art

[0002] Automated concrete forming equipment is equipment that automates the production of concrete products. The processes can be broadly categorized into batching, mixing, spreading, forming, and curing. Batching involves mixing the raw materials for concrete in a specific proportion into a storage hopper, mixing them in the storage hopper, and then pouring them into a distribution hopper for distribution. The distribution hopper then pours the concrete slurry into a test mold, and finally, the concrete is formed and cured. Currently, the mixing and spreading processes are primarily manual, requiring a large number of people, resulting in high labor intensity and low production efficiency.

[0003] To distribute the material, the utility model patent with authorization number CN212863229U discloses a single-side flip-over distribution device. The device includes a guide rail and a trolley slidably supported on the rail. The trolley is equipped with a distribution hopper. The top of the hopper has a feed port for receiving material, and the bottom of the hopper has a discharge port for distributing the material downward. A flap assembly is located at the discharge port of the hopper, which is used to close and open the discharge port. During use, the trolley slides to the feeding position, and the flap assembly opens the discharge port to distribute the material.

[0004] Although the existing technology can realize automatic material distribution, it is still necessary to manually add materials to the material distribution hopper. Moreover, since the feeding port of the material distribution hopper is located at the top, it is inconvenient to add materials, resulting in high labor intensity and low production efficiency for workers. Summary of the Invention

[0005] The present invention provides a material distribution system for automatic concrete product forming, so as to solve the technical problems in the prior art of manually adding materials into a material distribution hopper, which results in high labor intensity and low production efficiency.

[0006] To solve the above problems, the present invention provides a material distribution system for automated concrete product forming, which adopts the following technical solution: The material distribution system for automated concrete product forming comprises:

[0007] A lifting seat and a storage hopper mounted on the lifting seat and rotating around a horizontal axis. The storage hopper can be turned downward to discharge materials. The storage hopper is used to receive materials as the lifting seat descends, and is also used to turn over and discharge materials as the lifting seat rises.

[0008] The material distribution equipment includes a fixed track and a material distribution hopper slidably assembled on the fixed track. The top of the material distribution hopper is provided with a feed port for receiving the concrete slurry poured out from the storage hopper.

[0009] The cloth-feeding device further includes a movable track located at one end of the fixed track close to the storage hopper. The movable track has a connection position and an avoidance position in its movable stroke.

[0010] When in the connection position, the movable track is located below the cloth-feeding hopper and continues at one end of the fixed track for the cloth-feeding hopper to move below the storage hopper for receiving materials. When in the avoidance position, the movable track avoids the storage hopper to enable the lifting of the storage hopper.

[0011] The beneficial effects are as follows: The lifting seat can lift the storage hopper to a high position and then make the storage hopper turn over and pour materials, eliminating the need for manual feeding into the cloth-feeding hopper, saving labor, reducing labor intensity, and improving production efficiency. The provision of the movable track enables the cloth-feeding hopper to move below the storage hopper for receiving materials, preventing the concrete slurry from being poured outside the cloth-feeding hopper, thus avoiding pollution and waste. Moreover, the movable track can also be placed in the avoidance position to ensure the normal lifting of the lifting seat.

[0012] As a further improvement, the cloth-feeding device includes a flipping drive mechanism for driving the movable track to reciprocally flip between the connection position and the avoidance position.

[0013] As a further improvement, the cloth-feeding device includes a column. The movable track is rotationally assembled on the column around an axis extending vertically, and the flipping drive mechanism is used to drive the movable track to reciprocally flip on the horizontal plane.

[0014] As a further improvement, a rotating shaft is rotatably installed on the column. The movable track is rotationally assembled on the column through the rotating shaft, and a connecting plate is fixed on the rotating shaft. The flipping drive mechanism is a telescopic member directly or indirectly hinged to the fixed track, and the telescopic member is hinged to the connecting plate.

[0015] As a further improvement, the movable track has a connection end for connecting with the fixed track, and the rotating shaft is fixed to the connection end of the movable track.

[0016] As a further improvement, both the fixed track and the movable track include two guide rails arranged in parallel during use.

[0017] When in the avoidance position, the two guide rails of the movable track are stacked together along the extension direction of the fixed track.

[0018] As a further improvement, a support plate is provided at the bottom of the column, and a reinforcing rib is provided between the column and the support plate.

[0019] As a further improvement, a baffle is provided at one end of the movable track for engaging with the cloth-feeding hopper to limit the limit of the movement of the cloth-feeding hopper towards the direction where the storage hopper is located.

[0020] As a further improvement, the lifting seat is provided with a flipping mechanism for driving the storage hopper to flip and unload the materials. The flipping mechanism includes a flipping motor and two sprockets. A chain is installed between the two sprockets. One of the two chains is fixed on the storage hopper and arranged coaxially with the horizontal axis. The other of the two chains is connected to the flipping motor.

[0021] As a further improvement, the lifting seat includes an "L"-shaped base, which includes a vertical frame and a horizontal frame. The storage hopper is supported on the horizontal frame, and the flipping mechanism is used to drive the storage hopper to flip and dump materials toward the side away from the vertical frame.

Specific Embodiments

[0042] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present invention.

[0043] Next, referring to several representative embodiments of the present invention, the principles and spirit of the present invention will be explained in detail.

[0044] Embodiment 1 of the concrete product automatic forming batching system provided by the present invention:

[0045] As Figures 1 to 17 shown, the automatic forming batching system for concrete products (hereinafter referred to as the batching system) includes a batching device 100 and a pouring device 200. The function of the batching device 100 is to pour the concrete slurry into the test mold, and the function of the pouring device 200 is to pour the concrete slurry into the batching device 100.

[0046] The batching device 100 includes a batching machine frame 101. A fixed track is installed on the batching machine frame 101. For the convenience of description, in the horizontal plane, the extending direction of the fixed track is defined as the left-right direction, then the direction perpendicular to the left-right direction is the front-back direction. In this embodiment, the pouring device 200 is located on the left side of the batching device 100.

[0047] The fixed track includes a first fixed guide rail 102 and a second fixed guide rail 103. The first fixed guide rail 102 and the second fixed guide rail 103 are arranged at intervals in the front-back direction, and it is defined that the first fixed guide rail 102 is in the front and the second fixed guide rail 103 is in the back.

[0048] In this embodiment, both the first fixed guide rail 102 and the second fixed guide rail 103 are triangular guide rails. Support seats are slidably supported on both the first fixed guide rail 102 and the second fixed guide rail 103. Here, the support seat is an "L" - shaped plate 104. The "L" - shaped plate 104 includes a horizontal side 105 and a vertical side 106, and the horizontal side 105 is located at the top of the vertical side 106. A connecting beam 107 is connected between the vertical sides 106 of the two "L" - shaped plates 104. The connecting beam 107 and the two "L" - shaped plates 104 form an integral body.

[0049] The material distribution equipment 100 also includes two rail wheel mounting shafts 108 extending in the front-to-back direction and spaced apart in the left-to-right direction. Rail wheel mounting shafts 108 extend through the vertical sides 106 of the two L-shaped plates 104 in the front-to-back direction. Rail wheels 109 are rotatably mounted on each end of rail wheel mounting shafts 108. These rail wheels 109 are supported on the first and second fixed rails 102, 103, respectively, and are guided and moved along these rails.

[0050] The material distribution equipment 100 also includes a driving mechanism for driving the support seat to move back and forth left and right. The driving mechanism is a prior art and will not be described in detail here. For example, the driving mechanism can adopt a chain conveying mechanism.

[0051] The material distribution equipment 100 also includes a distribution hopper 110, with both ends of the distribution hopper 110 supported on corresponding support seats. Specifically, a first bearing seat 111 is fixedly mounted on the horizontal side 105 of each support seat. A first support shaft 112 is fixedly mounted on each end of the distribution hopper 110, and the first support shafts 112 at both ends are coaxially arranged. The first support shaft 112 penetrates the first bearing seat 111 on the corresponding side, allowing the distribution hopper 110 to rotate around the axis of the first support shaft 112. The top of the distribution hopper 110 is the distribution hopper feed port, and the side is provided with a discharge port 125. During use, concrete slurry is added to the distribution hopper 110 through the distribution hopper feed port. When the distribution hopper 110 rotates, the concrete slurry is poured out of the discharge port 125 and falls into the test mold below, achieving distribution.

[0052] In order to drive the material hopper 110 to flip and discharge the material, the material distribution equipment 100 also includes a first flipping mechanism, which includes a first flipping motor 113 fixedly mounted on the horizontal side of one of the support seats, and the first flipping motor 113 is connected to a first reducer 114, and a first gear 115 is mounted on the output shaft of the first reducer 114. A second gear 116 is fixedly mounted on the material distribution hopper 110, and the first gear 115 and the second gear 116 are engaged with each other. The material distribution hopper 110 is driven by the first flipping motor 113 to flip the material.

[0053] like Figures 8 to 17 As shown, the material unloading device 200 includes a fixed lifting frame 201, on which a lifting base is mounted for vertical sliding movement. The lifting base comprises an L-shaped base 202, which includes a vertical frame 203 and a transverse frame. The transverse frame comprises two cross braces 204 mounted on the vertical frame and connected to the lower ends of the vertical frame 203. The cross braces 204 extend in the left-right direction and are spaced apart in the front-back direction.

[0054] In this embodiment, the lifting frame 201 includes two vertically arranged I-beams 205. The two I-beams 205 are arranged at intervals in the front-rear direction, and the webs 206 of the I-beams 205 extend in the left-right direction. Two ear plates 207 are respectively fixed at the front and rear ends of the vertical frame body 203. As Figure 12 shown, the two ear plates 207 at the same end are located on the front and rear sides of the I-beam 205. A first guide wheel 208 is rotatably installed between the two ear plates 207 at the same end through a first guide wheel mounting shaft 231. The rotation axis of the first guide wheel 208 extends in the front-rear direction, and the first guide wheel 208 is attached to the outer side surface of the flange 209 of the I-beam 205.

[0055] Meanwhile, as Figure 12 shown, a second guide wheel 211 is rotatably installed at the upper end of each ear plate 207 through a second guide wheel mounting shaft 210. The axis of the second guide wheel mounting shaft 210 extends in the front-rear direction. The second guide wheel 211 is attached to the inner side surface of the flange 209. Since the inner side surface of the flange 209 has a certain taper, in order to satisfy the fitting of the second guide wheel 211 with the inner side surface of the flange 209, the second guide wheel 211 is of a frustum structure. The first guide wheel 208 and the second guide wheel 211 clamp the I-beam 205 in the front-rear direction, thereby positioning the left-right position of the lifting seat. At the same time, the two second guide wheels 211 corresponding to the same I-beam 205 are in contact with the inner side surface of the flange 209 to position the front-rear position of the lifting seat.

[0056] Two positioning plates 212 arranged in the front-rear direction are also fixedly installed on the vertical frame body 203. The positioning plates 212 extend in the up-down direction as a whole. Here, the positioning plates 212 are "L"-shaped plates. The positioning plates include a first side 213 and a second side 214. The plate surface of the first side 213 is perpendicular to the front-rear direction, and the plate surface of the second side 214 is perpendicular to the left-right direction. The second side 214 is fixed on the vertical frame body 203. A long hole 215 extending in the up-down direction is formed in the first side 213. A positioning rod 216 is fixedly installed on the lifting frame 201. The positioning rod 216 penetrates into the long hole in the front-rear direction, and the positioning rod 216 is in a blocking fit with the hole wall of the long hole 215 in the left-right direction to limit the left-right position of the lifting seat.

[0057] The lifting seat further includes a storage hopper frame body 217 placed on the cross brace 204 in the base 202. A storage hopper 218 is rotatably installed on the storage hopper frame body 217. Specifically, the storage hopper 218 has a structure with an open top and a closed perimeter. Two second bearing seats 219 are fixedly installed on the storage hopper frame body 217, and the two second bearing seats 219 are arranged at intervals in the front-back direction. Through holes are provided on both the front and rear sides of the storage hopper 218, and the through holes on the front and rear sides are coaxially arranged. A support shaft 220 is inserted into the through holes of the storage hopper 218, and both ends of the support shaft 220 are inserted into the corresponding second bearing seat 219 on one side. At the same time, third bearing seats 221 are fixedly installed on the outer sides of the front and rear sides of the storage hopper 218, and the support shaft 220 passes through the two third bearing seats 221. That is, the storage hopper 218 is supported on the support shaft 220 through the third bearing seats 221, and is indirectly supported on the second bearing seats 219 through the support shaft 220.

[0058] A first sprocket 222 is fixed to the outer side of one side of the storage hopper 218 in the front-back direction, and the central axis of the first sprocket 222 is collinear with the central axis of the support shaft 220. A second turning motor 223 is fixedly installed on the storage hopper frame body 217. A second speed reducer 224 is connected to the output shaft of the second turning motor 223, and a second sprocket 225 is fixed to the output shaft of the second speed reducer 224. A first chain 226 is wound around between the first sprocket 222 and the second sprocket 225. The second turning motor 223 drives the storage hopper 218 to turn around the central axis of the support shaft 220, so as to pour the materials.

[0059] To drive the lifting seat to lift, a lifting mechanism is installed on the lifting frame 201. Specifically, the lifting mechanism includes an oil cylinder 227 installed on the lifting frame 201. The cylinder body of the oil cylinder 227 is fixed to the lifting frame 201, and a sprocket mounting frame 228 is fixedly installed on the piston rod of the oil cylinder 227. The sprocket mounting frame 228 includes a vertical shaft and a horizontal shaft fixed to the vertical shaft, and the horizontal shaft extends in the front-back direction. Third sprockets 229 are respectively rotatably installed at both ends of the horizontal shaft, and a second chain 230 is wound around the third sprockets 229. One end of the second chain 230 is fixed to the vertical frame body 203 of the lifting seat, and the other end of the second chain 230 is fixed to the lifting frame 201. When the oil cylinder 227 expands and contracts, it can drive the lifting seat to lift through the second chain 230.

[0060] After the distributing hopper 110 completes one round of material distribution, it needs to be moved below the storage hopper 218 to receive the materials. In order to reduce the amount of concrete slurry poured outside the distributing hopper 110, or even to avoid pouring the concrete slurry outside the distributing hopper 110, the distributing hopper 110 needs to be moved below the storage hopper 218.

[0061] To achieve this purpose, in this embodiment, a movable track is also movably arranged on the left side of the fixed track. When the cloth hopper 110 needs to receive materials, the movable track is placed below the storage hopper 218 and continues at the left end of the fixed track, so that the cloth hopper 110 can move below the storage hopper 218 to receive materials. At this time, the movable track is defined to be in the continuous position. When the cloth hopper 110 does not need to receive materials, the movable track is placed on the horizontal side of the storage hopper 218 to avoid interference of the movable track with the lifting of the storage hopper. At this time, the movable track is defined to be in the avoidance position.

[0062] Specifically, the movable track includes a first movable guide rail 117 and a second movable guide rail 118. The first movable guide rail 117 is used to continue at the left end of the first fixed guide rail 102, and the second movable guide rail 118 is used to continue at the left end of the second fixed guide rail 103. Correspondingly, both the first movable guide rail 117 and the second movable guide rail 118 are triangular guide rails.

[0063] The cloth feeding device 100 further includes columns 119 corresponding to each movable guide rail. The column 119 corresponding to the first movable guide rail 117 is located in front of the column 119 corresponding to the second movable guide rail 118. A rotating shaft 120 is rotatably installed in the column 119 around an axis extending vertically. A support plate 126 is fixed to the bottom of the column 119, and a reinforcing rib 127 is installed between the support plate 126 and the column 119.

[0064] To drive the rotating shaft 120 to rotate, a connecting plate 121 is fixedly installed on one side of the rotating shaft 120. A cylinder 128 is connected between the connecting plate 121 and the cloth feeding frame 101. The cylinder body of the cylinder 128 is hinged to the cloth feeding frame 101, and the piston rod of the cylinder 128 is hinged to the connecting plate 121 (the cylinder 128 is not connected to the connecting plate 121 in the figure). The rotation of the rotating shaft 120 is driven by the expansion and contraction of the cylinder 128.

[0065] One end of the movable guide rail used to continue to the fixed guide rail is fixedly installed on the top of the rotating shaft 120. Specifically, a guide rail mounting seat 122 is fixedly installed on the top of the rotating shaft 120, and the movable guide rail is fixed on the guide rail mounting seat 122.

[0066] Among them, the column 119 corresponding to the first movable guide rail 117 is located on the right side of the column 119 corresponding to the second movable guide rail 118. When the movable track is in the avoidance position, the first movable guide rail 117 and the second movable guide rail 118 are stacked in the left-right direction, with the first movable guide rail 117 on the right and the second movable guide rail 118 on the left. To ensure that the left ends of the first movable guide rail 117 and the second movable guide rail 118 are flush when the movable track is in the continuous position, the length of the first movable guide rail 117 is greater than the length of the second movable guide rail 118.

[0067] In order to limit the leftward movement of the distribution hopper 110 and prevent the distribution hopper 110 from falling off the movable track, baffles 123 are fixed at the ends of the first movable guide rail 117 and the second movable guide rail 118, and anti-falling is achieved by the blocking cooperation between the baffles and the support seat.

[0068] In order to ensure that the movable guide rail can be smoothly connected to the fixed guide rail when rotating, the ends of the movable guide rail and the fixed guide rail are both provided with inclined surfaces 124.

[0069] During use, the movable track is first placed in the avoidance position, and the storage hopper 218 moves downward to the low position to receive the material. After receiving the material, it is driven by the lifting seat to move upward. After the distribution hopper 110 has completed a round of distribution, the movable track is placed in the connection position, and the distribution hopper 110 moves left to below the storage hopper 218. The second turning motor 223 is activated, and the storage hopper 218 turns right to discharge the material. The distribution hopper 110 receives the concrete slurry and then distributes the material again. The movable track is then placed in the avoidance position.

[0070] In this embodiment, the cylinder, the connecting plate, and the rotating shaft together form a turning drive mechanism, which is used to drive the movable track to turn back and forth. The cylinder constitutes the telescopic member in the turning drive mechanism. In other embodiments, the telescopic member can be an oil cylinder or an electric push rod.

[0071] In this embodiment, the right end of the movable track is used to connect to the fixed track when in use, and this end is the connecting end of the movable track.

[0072] In this embodiment, the oil cylinder on the lifting seat, the sprocket mounting frame, the third sprocket 229, and the second chain 230 together constitute a turning mechanism.

[0073] It should be noted that, in actual use, the concrete raw materials can be added to the storage hopper 218 and then stirred, or the evenly stirred concrete slurry can be directly added to the storage hopper 218 .

[0075] The main difference between it and embodiment 1 is that in embodiment 1, when the movable track is in the avoidance position, the two movable guide rails are stacked together.

[0076] In this embodiment, when the movable rail moves from the connecting position to the avoiding position, the two movable guide rails rotate in directions away from each other.
