Description
Technical Field
[0001] This utility model belongs to the field of mortar screening technology, and in particular relates to a raw material screening device for mortar production. Background Technology
[0002] Mortar plays a vital role in construction engineering. It is not only a key material for bonding bricks, stones, blocks and other blocks into masonry, but also plays a core role in bonding, padding and force transmission in building structures. From foundation to roof, from load-bearing structure to decorative surface layer, the performance and reasonable application of mortar directly determine the safety, durability and functionality of building projects.
[0003] Currently, when disassembling mortar raw material screening devices, wrenches and screwdrivers are usually required to disassemble the outer shell, support, and other components layer by layer. Some bolts are hidden in narrow spaces, making it difficult to use wrenches. Operators have to adjust their body posture and operate at awkward angles, which not only consumes physical strength but also greatly reduces disassembly efficiency, resulting in a single disassembly taking up to half an hour to an hour. Therefore, we have proposed a raw material screening device for mortar production. Utility Model Content
[0004] The purpose of this utility model is to provide a raw material screening device for mortar production. By setting up a disassembly component, specifically when replacing the screen plate, pulling the button moves the slide rod and the fixedly connected limit plate upward, compressing the spring and causing the slide rod to disengage from the screen plate slot. Then, the screen plate can be pulled out from the plug plate for replacement, which greatly reduces downtime and improves equipment maintenance efficiency. It solves the problem that when disassembling existing mortar raw material screening devices, wrenches and screwdrivers are usually needed to disassemble the outer shell, bracket and other components layer by layer. Some bolts are hidden in narrow spaces, making it difficult to use a wrench. Operators have to adjust their body posture and operate at awkward angles, which not only consumes physical strength, but also greatly reduces disassembly efficiency, resulting in a single disassembly taking half an hour to an hour.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a raw material screening device for mortar production, comprising a box body, four support legs at the bottom of the box body, a feed inlet at the top of the box body, and two screen plates inside the box body.

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 scope of protection of the present utility model.
[0033] Please see Figures 1-5 As shown, this utility model is a raw material screening device for mortar production, including a box body 1, four support legs 111 at the bottom of the box body 1, a feed inlet 112 at the top of the box body 1, and two screen plates 113 inside the box body 1. The parts connected to the two screen plates 113 are identical. It also includes:
[0034] Disassembly mechanism 2 is located on the left and right sides of housing 1. Disassembly mechanism 2 is used for quick disassembly of screen plate 113.
[0035] Vibration mechanism 3 is installed on the left and right sides of screen plate 113. Vibration mechanism 3 is used to vibrate screen plate 113.
[0036] The disassembly mechanism 2 includes a disassembly assembly 21, which is installed on the left and right sides of the screen plate 113. The disassembly assembly 21 is used for quick replacement of the screen plate 113.
[0037] The deceleration assembly 22 is installed on the top of the screen plate 113 and is used to decelerate the material.
[0038] The vibration mechanism 3 includes a collection component 32, which is installed on the front of the housing 1 and is used to collect the material after screening.
[0039] The disassembly assembly 21 includes support frames 211 installed on the left and right sides of the screen plate 113. A slide rod 212 is slidably connected inside each support frame 211, and a spring 213 is installed on the outer surface of the slide rod 212. Specifically, when replacing the screen plate 113, the button 215 is pulled, which moves the slide rod 212 and the limiting plate 214 fixedly connected to 212 upward, squeezing the spring 213 and causing the slide rod 212 to disengage from the slot of the screen plate 113. Then the screen plate 113 can be pulled out from the plug-in plate 315 for replacement, which greatly reduces downtime and improves equipment maintenance efficiency.
[0040] Among them, limit plates 214 are installed on the outer surface of both slide rods 212, and buttons 215 are installed on the side of the two slide rods 212 that are far apart from each other.
[0041] The deceleration assembly 22 includes several rotating shafts 221, which are rotatably connected to the top of the screen plate 113. Each of the rotating shafts 221 has a deceleration plate 222 installed on its outer surface. Specifically, when the mortar raw material falls onto the vibrating screen plate 113 for screening, large particles roll to the bottom and small particles pass through the screen. The rolling material will push the deceleration plate 222 to rotate, slowing down the movement speed of the particles, extending their residence time on the screen plate, reducing the phenomenon of missed screening caused by rapid slippage, and improving the screening accuracy.
[0042] The vibration mechanism 3 includes four slide rods 311 installed on the left and right sides of the screen plate 113. Each of the four slide rods 311 has a slider 312 slidably connected to its outer surface. Each of the four sliders 312 has a spring 313 installed on its top and a spring 314 installed on its bottom. Two plug-in plates 315 are installed on the side of the four sliders 312 that are close to each other. Four baffles 316 are installed on the top of the two plug-in plates 315.
[0043] Among them, a motor 317 is installed on the left side of the housing 1, and a collision block 318 is fixedly connected to the output end of the motor 317 through a coupling.
[0044] The collection component 32 includes a collection box 321 installed on the front of the box 1, a sieve plate 113 at the top with a slot 1 at the bottom, and a sieve plate 113 at the bottom with a slot 2 at the bottom.
[0045] Among them, a second collection box 322 is installed at the bottom of the second slot, and a third collection box 323 is installed at the bottom of the sieve plate 113. The third collection box 323 is slidably connected to the box body 1.
[0046] A specific application of this embodiment is as follows: In use, mortar raw materials are first poured into the box 1 through the feed inlet 112. Then, the motor 317 is started to drive the collision block 318 to rotate. While the collision block 318 is rotating, it will collide with the two screen plates 113. At this time, when the collision block 318 hits the upper screen plate 113, the screen plate 113 drives the insertion plate 315 to move upward. Since the insertion plate 315 is fixedly connected to the slider 312, when the insertion plate 315 moves upward, it will drive the slider 312 to move upward. At this time, the slider 312 compresses the second spring 313. When the collision block... After the protruding part 318 rotates, it pushes the slider 312 downward under the elastic action of the second spring 313. At this time, the slider 312 slides on the second slide rod 311. This reciprocating motion continuously generates vibration, reducing energy consumption and making the material screening more uniform. Since the two screen plates 113 are set at an incline, when the mortar raw material falls into the top of the screen plate 113, it will be screened by vibration. Larger materials will roll to the bottom of the screen plate 113, and smaller materials will fall onto the bottom screen plate 113 for screening. When the material rolls to the bottom of the screen plate 113, it will push the deceleration plate 222 to rotate. The deceleration plate 222 slows down the material, allowing it to remain on the screen plate for a longer time and thus providing more time for it to pass through the screen. When passing the deceleration plate 222, the material on the upper screen plate 113 flows into the first collection box 321, while the material on the lower screen plate 113 rolls into the second collection box 322. Finer materials fall into the third collection box 323 at the bottom of the screen plate 113. When the screen plate 113 needs to be replaced, first pull the button 215, which, through the slide rod 212, moves the limiting plate 214 upwards. Since the limiting plate 214 is fixedly connected to the slide rod 212, ... When the limiting plate 214 moves upward, it will compress the spring 213. At this time, the slide rod 212 will disengage from the slot of the screen plate 113. Simultaneously, the user can pull the screen plate 113 out of the plug-in plate 315 for replacement. When the user releases their hand, the screen plate 113 will be reset under the elastic action of the spring 213. When installing, first pull the button 215 to move the limiting plate 214 upward through the slide rod 212, while compressing the spring 213. At this time, the screen plate 113 to be replaced can be inserted into the plug-in plate 315. Then the user can release their hand, and the screen plate 113 will be reset under the action of the spring 213.
