Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and specifically discloses a batching station for concrete production. Background Technology

[0002] Chinese patent application CN202021994781.8 discloses a concrete batching plant; it includes a batching machine, with multiple storage bins at the top of the batching machine, and a receiving bin below each storage bin. A conveyor belt for conveying materials is installed between the storage bins and the receiving bin. A sand and gravel screen for screening materials is installed inside each storage bin. A rotating rod is installed on the sand and gravel screen, located in the middle of the screen. Slots are formed on the inner walls of both sides of the storage bins, and the two ends of the rotating rod are respectively fitted with two slots with clearance. A drive assembly for driving the sand and gravel screen to vibrate is installed on the sand and gravel screen. This application has the effect of ensuring the quality of concrete to a certain extent.

[0003] During the process of the screen frame reciprocating around the axis of the rotating rod under the drive of the drive motor, sand and gravel particles are easily stuck between the storage bin and the screen frame, which can easily cause wear and reduce its service life. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a batching station for concrete production, including a storage silo. A feeding hopper is movably fitted inside the top of the storage silo. A first fixed rod and a second fixed rod are fixedly fitted inside the storage silo, and a crankshaft is rotatably connected thereto. A swing arm is rotatably connected to the outer side of both the first and second fixed rods. A pin is rotatably connected inside the swing arm. A screen frame located below the feeding hopper is fixedly fitted to the outer side of the pin shaft extending from both ends of the first and second fixed rods. A connecting plate is provided on one side of the bottom of the screen frame. Guide blocks symmetrically distributed on the outer side of the crankshaft are provided at the bottom of the connecting plate. A screen mesh is fitted inside the screen frame, and a fixed frame located above the screen mesh is fitted inside the screen frame. A positioning rod with one end movably fitted inside the fixed frame is movably fitted inside the inner side of both sides of the screen frame. A drive motor fixedly installed outside the storage silo is fixedly fitted to the outer side of the crankshaft extending outside the storage silo through a bushing.

[0005] Preferably, the screen frame is internally fitted with a fixing pin that is movably engaged inside the positioning rod.

[0006] Preferably, the bottom of the inner side of the sieve frame is provided with symmetrically distributed limiting posts that are movably sleeved inside the sieve mesh, and the bottom of the fixed frame is provided with an annular groove located outside the limiting posts.

[0007] Preferably, the outer side of the feed hopper is provided with reinforcing plates that are evenly spaced and located inside the storage bin.

[0008] The advantages of this utility model are as follows:

[0009] 1. This concrete production batching station, through the practical cooperation of the first fixed rod, the second fixed rod, the swing arm, and the pin shaft, allows the screen frame to be placed between the storage bin and the feed hopper. Driven by the drive motor, the crankshaft rotates, causing the screen frame to reciprocate around the axial direction of the first and second fixed rods. This allows the screen mesh to screen the sand and gravel located inside the fixed frame. This structure ensures that the screen frame does not contact the storage bin and the feed hopper during the sand and gravel screening process, thereby reducing the wear of parts and increasing their service life.

[0010] 2. The batching station for concrete production can limit the screen by using the limiting column, so that the screen is subjected to more uniform force during the screening of sand and gravel, thus ensuring that the screen is not easily damaged when subjected to external force.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0020] The accompanying drawings in this utility model embodiment: different types of cross-sectional lines in the drawings are not labeled according to national standards, nor do they specify the material requirements of the components. They are used to distinguish the cross-sectional views of the components in the drawings.

[0021] Please see Figure 1-6 A batching station for concrete production includes a storage silo 1. A feed hopper 2 is movably fitted inside the top of the storage silo 1, facilitating the addition of sand and gravel to the inside of a fixed frame 12. A first fixed rod 3 and a second fixed rod 4 are fixedly fitted inside the storage silo 1, and a crankshaft 5 is rotatably connected thereto. A swing arm 6 is rotatably connected to the outer sides of both the first fixed rod 3 and the second fixed rod 4. A pin 7 is rotatably connected inside the swing arm 6. A screen frame 8, located below the feed hopper 2, is fixedly fitted to the outer sides of the pin 7 extending from both ends of the first fixed rod 3 and the second fixed rod 4. The first fixed rod 3, the second fixed rod 4, the swing arm 6, and the screen frame 8 form a parallelogram mechanism. A connecting plate 9 is provided on one side of the bottom of the screen frame 8. Guide blocks 10, symmetrically distributed on the outer sides of the crankshaft 5, are provided at the bottom of the connecting plate 9. When the crankshaft 5 rotates, it can drive the screen 11 inside the screen frame 8 to reciprocate around the axis of the first fixed rod 3 and the second fixed rod 4, thereby screening the sand and gravel through the screen 11. The guide block 11 does not completely limit the crankshaft 5, so that the screen frame 8 can be snapped on top of the crankshaft 5 for easy assembly and disassembly of the screen frame 8. The screen 11 is fitted inside the screen frame 8, and a fixed frame 12 located above the screen 11 is fitted inside the screen frame 8. A positioning rod 13 is movably fitted inside both sides of the screen frame 8, with one end movably sleeved inside the fixed frame 12. The positioning rod 13 can limit the fixed frame 12 to prevent it from detaching from the inside of the screen frame 8. The drive motor 14, which is fixedly installed on the outside of the storage bin 1, is fixedly sleeved on the outside of the crankshaft 5 extending outside the storage bin 1 through a bushing.

[0022] The screen frame 8 has a movable internal fitting with a fixing pin 15 that is movably fitted inside the positioning rod 13. The fixing pin 15 can limit the positioning rod 13 to prevent it from detaching from the inside of the screen frame 8, thereby ensuring that the positioning rod 13 can stably limit and fix the fixed frame 12.

[0023] The bottom of the inner side of the screen frame 8 is provided with symmetrically distributed limiting posts 16 that are movably sleeved inside the screen mesh 11. The bottom of the fixed frame 12 is provided with an annular groove 17 located outside the limiting posts 16. The limiting posts 16 can be positioned by the annular groove 17, so that after the fixed frame 12 is fixed, it can press and fix the screen mesh 11 to the inner side of the screen frame 8.

[0024] The feed hopper 2 is provided with reinforcing plates 18 that are evenly distributed on the outside and located inside the storage bin 1. The reinforcing plates 18 can increase the structural strength of the feed hopper 2, so that when sand and gravel are added to the inside of the screen frame 8, the feed hopper 2 is not easily deformed. Furthermore, by disassembling the feed hopper 2, the fixing pin 15 and the positioning rod 13 can be disassembled, so as to facilitate the disassembly and replacement of the screen 11.

[0025] When screening sand and gravel, the drive motor 14 is started. The drive motor 14 drives the crankshaft 5 to rotate, and at the same time, the guide block 10 pushes the screen frame 8 to swing back and forth around the first fixed rod 3 and the second fixed rod 4. The screen frame 8 swings at the same time, and the screen mesh 11 swings synchronously. At this time, sand and gravel are added to the inside of the screen frame 8 through the feed hopper 2. After the sand and gravel fall onto the surface of the screen mesh 11, they are screened by the screen mesh 11. Large sand and gravel particles gather towards the middle of the screen mesh 11 under the action of their own inertial force. After the batching station stops, the collected large sand and gravel particles can be manually cleaned up.
