Description

Technical Field

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

[0002] Concrete production refers to the manufacture of concrete. The concrete production process requires strict control over the concrete mix proportions, which necessitates concrete batching machines. Concrete batching machines, also known as batching machines or automatic aggregate batching machines, are automated equipment used for the quantitative distribution of various materials such as sand and gravel. They are mainly used in the concrete construction industry to replace manual weighing or volumetric metering methods. Therefore, concrete batching machines are particularly needed for concrete production.

[0003] Chinese utility model patent application number 202321101284.4 provides a concrete batching machine for concrete production. Through the setting of the installation mechanism and screen, the screen and fixed frame are slid into the interior of the slide groove by a slider. At this time, the slide groove will squeeze the locking pin and then squeeze the spring. Then the slider slides to the bottom of the slide groove, the spring resets and pushes the locking pin into the interior of the locking hole, thereby completing the installation and fixing of the screen and fixed frame. During use, the screen can filter out the raw materials with larger particles.

[0004] However, during the use of the above equipment, it was found that after the screen and the fixed frame are fixed, for the filtration of materials, larger particles of raw materials are filtered and left on the screen. Over time, they will accumulate and clog the screen holes, affecting the filtration efficiency and effect, and causing some raw materials that should be filtered to remain on the screen. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete batching machine for concrete production, which solves the problem mentioned in the background technology that large-particle raw materials remain on the screen after filtration, and will accumulate and clog the screen holes after long-term use, affecting filtration efficiency and effect, and causing some raw materials that should be filtered to remain on the screen.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A concrete batching machine for concrete production includes a storage bin and a screening bin. The screening bin is located below the storage bin. A sliding rod is fixedly installed on the top of the inner cavity of the screening bin, and a mounting frame is slidably installed on the sliding rod. A drive groove is provided on one side of the mounting frame, and racks are provided at the top and bottom of the inner side of the drive groove.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figures 1-5 This utility model provides a concrete batching machine for concrete production, including a storage box 1 and a screening box 2. The screening box 2 is located below the storage box 1. A sliding rod 22 is fixedly installed on the top of the inner cavity of the screening box 2. A mounting frame 4 is slidably installed on the sliding rod 22. A drive groove 41 is provided on one side of the mounting frame 4. A rack 42 is provided on the top and bottom of the inner side of the drive groove 41. A first motor 23 is installed on the inner wall of the screening box 2. A sector gear 231 is connected to the output end of the first motor 23. The sector gear 231 meshes with the rack 42. A screening frame 3 is installed on the mounting frame 4. A discharge port 21 is provided at the bottom of the inner cavity of the screening box 2. A screen 31 is provided in the screening frame 3. An opening is provided on one side of the screening frame 3.

[0027] The screen 31 is inclined toward the opening of the screening frame 3, and the opening of the screening frame 3 is located above the screening box 2.

[0028] A positioning frame 32 is provided at the bottom of the screening frame 3. The positioning frame 32 is adapted to the mounting frame 4. A positioning hole 33 is provided on the positioning frame 32.

[0029] A limit frame 43 is fixedly installed on the mounting bracket 4. A pull rod 44 is slidably arranged in the limit frame 43. A positioning rod 46 is fixedly connected to one end of the pull rod 44. The positioning rod 46 is adapted to the positioning hole 33. The positioning rod 46 is connected to the limit frame 43 through a spring 45.

[0030] Specifically, the raw material in storage bin 1 falls into screening frame 3 within screening bin 2, and the first motor 23 starts, causing the sector gear 231 at its output end to rotate. The sector gear 231 meshes with the racks 42 at the top and bottom of the drive groove 41 of the mounting frame 4. Since only a portion of the sector gear 231 has teeth, as it continues to rotate, it alternately meshes with the racks 42 at the top and bottom of the drive groove 41. When the sector gear 231 meshes with the top rack 42, it drives the mounting frame 4 to slide in one direction; when the sector gear 231 continues to rotate and meshes with the bottom rack 42, it drives the mounting frame 4 to slide in the opposite direction. This cycle achieves the reciprocating linear motion of the mounting frame 4 on the slide bar 22. The screening frame 3 is mounted on the mounting frame 4, so the screening frame 3 will also reciprocate, allowing the screen 31 to screen the raw materials. During the screening process, smaller raw materials fall through the screen 31 into the bottom of the inner cavity of the screening box 2 and are discharged from the outlet 21; while larger raw materials remain on the screen 31. Due to the inclination of the screen 31, the larger raw materials will gradually move towards the opening of the screening frame 3 and eventually be discharged from the opening into the screening box 2. The inclination slope of the screen 31 is small, which can prevent the raw materials from sliding down quickly.

[0031] When it is necessary to disassemble the screening frame 3, manually pull the sliding rod 44 in the limiting frame 43. The movement of the rod 44 will cause the positioning rod 46, which is fixedly connected to it, to move together, and at the same time compress the spring 45. As the rod 44 is pulled, the positioning rod 46 will gradually disengage from the positioning hole 33 of the positioning frame 32. When the positioning rod 46 is completely disengaged from the positioning hole 33, the fixed constraint between the screening frame 3 and the mounting frame 4 is released. At this time, the screening frame 3 can be removed from the mounting frame 4, completing the disassembly operation of the screening frame 3.

[0032] When installing the screening frame 3, align the positioning frame 32 at the bottom of the screening frame 3 with the mounting frame 4, ensuring the positioning frame 32 fits the mounting frame 4. Simultaneously, align the positioning hole 33 on the positioning frame 32 with the positioning rod 46 fixedly connected to one end of the pull rod 44 in the upper limit bracket 43 of the mounting frame 4. After aligning the positioning frame 32 and the mounting frame 4, release the pull rod 44. Under the action of the spring 45, the positioning rod 46 will be pushed towards the positioning hole 33 and inserted into it. Because the spring 45 provides continuous elastic force, the positioning rod 46 is stably held within the positioning hole 33, thus securely mounting the screening frame 3 onto the mounting frame 4.

[0033] Furthermore, to prevent excessive raw material from entering screening frame 3, please refer to [link / reference needed]. Figures 1-5 The bottom of the storage box 1 is provided with a discharge chute 11, which corresponds to the screening frame 3;

[0034] A metering roller 13 is rotatably installed in the discharge trough 11. A metering groove 131 is opened on the metering roller 13. The metering roller 13 is connected to the output end of the second motor 12. The second motor 12 is installed on the bottom outer wall of the storage box 1.

[0035] Specifically, after the second motor 12 starts, it drives the metering roller 13 connected to its output end to rotate. Since the metering roller 13 has a metering groove 131, the raw material in the storage bin 1 falls through the discharge chute 11. Only the raw material entering the metering groove 131 can be carried to the outlet of the discharge chute 11 with the rotation of the metering roller 13, and then fall into the screening frame 3. By controlling the volume of the metering groove 131, the amount of raw material entering the screening frame 3 each time can be controlled, preventing excessive raw material from entering and keeping the amount of raw material entering the screening frame 3 within a suitable range. This avoids the accumulation of raw material in the screening frame 3, which could lead to clogging of the screen 31 or insufficient screening, allowing the screen 31 to function fully, improving screening efficiency, and ensuring the quality of concrete batching.

[0036] Working principle: Align the bottom positioning frame 32 of the screening frame 3 with the mounting frame 4 so that the positioning hole 33 corresponds to the positioning rod 46. Release the pull rod 44, and the spring 45 pushes the positioning rod 46 into the positioning hole 33 to complete the installation of the screening frame 3. Add raw materials to the storage box 1 and let them fall into the quantitative groove 131 on the quantitative roller 13 under the action of gravity. Start the second motor 12 to drive the quantitative roller 13 to rotate. The raw materials in the quantitative groove 131 are carried to the outlet of the discharge chute 11 and fall into the screening frame 3.

[0037] When the first motor 23 is started, the sector gear 231 at its output end rotates and alternately meshes with the rack 42 at the top and bottom of the drive groove 41, driving the mounting frame 4 and the screening frame 3 to reciprocate. The screen 31 screens the raw materials. Small particles of raw materials fall into the bottom of the screening box 2 and are discharged from the discharge port 21, while large particles of raw materials are discharged from the opening along the inclined screen 31.
