Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a quantitative feeding device for building construction. Background Art

[0002] The quantitative feeding device for construction is a device that realizes the quantitative feeding of materials during the construction process. It is usually used for concrete preparation, sand and stone mixing, etc. to ensure that the materials are added to the mixture according to the predetermined amount. Before mixing the sand and stone, the sand and stone need to be quantitatively fed separately. However, the stone has an irregular shape, a large gravity, and a large inertia during transportation, making it relatively difficult to quantify.

[0003] The patent with the patent announcement number CN211886686U discloses a quantitative conveying and mixing device for building construction materials. The materials in this patent are conveyed and transported by the belt strip at the upper end of the conveyor. The power is driven by the driving force of the motor to drive the driving shaft for power transmission. The differential installed inside the conveyor is connected to ensure that the main pulley connected to the belt strip will not run too fast in coordination with the tail pulley at the rear end. In addition, there is a quantitative groove at the upper end of the belt strip to convey the material weight, and several rollers are installed at the lower end to make the conveying process more stable to avoid scattering. Finally, the buffer discharge mechanism is used for the final collection from the belt strip. The material on the upper part falls into the conical feed port at the upper end of the anti-corrosion shell, and the material begins to scatter. The lower end is also provided with layers of feeding spirals to ensure that the fallen material will not clump and increase the effect of buffering scattering. The fixing rods on both sides improve the fixation to prevent loosening, and finally the material is sent out from the discharge port at the bottom of the inner cavity groove, which reduces the overall labor consumption, improves the stability of quantitative material distribution and avoids the agglomeration of material distribution, and ensures the quality of the material after mixing and proportioning. Although this patent solves the above problems, there are still problems such as inaccurate quantitative distribution and inertia of materials, and it is impossible to ensure that the materials fall accurately into the quantitative embedding groove. Therefore, a quantitative feeding device for construction is proposed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a quantitative feeding device for construction in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a quantitative feeding device for construction construction, comprising a feed box, the bottom surface of the feed box is fixedly connected with a support column, the rear side surface of the inner wall of the feed box is fixedly connected with a laser ranging sensor, the bottom surface of the inner wall of the feed box is fixedly connected with a hydraulic rod, two sides of the feed box are provided with a slide groove, the front side surface of the feed box is fixedly connected with a feeding frame, the top of the hydraulic rod is fixedly connected with a receiving plate, the lower surface of the receiving plate is fixedly connected with a spring buffer column, the upper surface of the receiving plate is fixedly connected with a connecting piece at both sides, the side of the connecting piece close to the inner wall of the feed box is fixedly connected with a sliding shaft, the outer surface of the feed box is fixedly connected with support pieces at both sides, and the inner surface of the support piece The transmission gear of the present invention is a gear shifting device, and the gear shifting device is a gear shifting device, and the gear shifting device is a gear shifting device for shifting the gears to the frame, and the gear shifting device is a gear shifting device for shifting the gears to the frame. The bottom end is fixedly connected to the bottom surface of the inner wall of the feed box, the sliding shaft 1 is slidably connected to the inner surface of the slide slot 1, the sliding shaft 1 is slidably connected to the inner surface of the inclined slot transmission frame, the transmission bent rod is slidably connected to the inner surface of the support, the sliding shaft 2 is hinged to the inner surface of the transmission sleeve shaft, the limit clamping rod is slidably connected to the inner surface of the feeding frame, and the stone is put into the feed box, and the stone falls onto the receiving plate in the feed box. The receiving plate moves downward under the influence of the weight of the stone, and drives the spring buffer column to contract. The elastic action of the spring buffer column buffers the receiving plate. When the receiving plate steadily drops to a certain position, the laser distance sensor measures the distance to it. When the distance between the receiving plate and the laser distance sensor reaches the set value, it means that the stone entering the feed box has reached a certain quantity. At this time, the stone falls from the receiving plate into the feeding frame, and then the laser ranging sensor transmits a signal to the hydraulic rod. After receiving the signal, the hydraulic rod starts and holds the receiving plate. In the process of the stone entering the feeding frame, the hydraulic rod slowly rises, driving the receiving plate to slowly rise, and finally blocks the feeding box to prevent the stone from entering the feeding box. The stone entering the feeding frame rolls forward through the inclined surface of the feeding frame and then stops after being blocked by the baffle. Then the hydraulic rod drives the receiving plate to descend, and the receiving plate drives the connecting piece to descend, and the connecting piece drives the sliding shaft to slide downward in the sliding groove. When the sliding shaft slides downward, it is driven forward by the guide of the inclined groove in the inclined groove transmission frame, and the inclined groove transmission frame drives the supporting slide rod and the transmission bent rod to slide forward in the supporting piece, and the transmission bent rod drives the transmission sleeve shaft to move forward.The forward force of the transmission sleeve shaft is transmitted to the sliding shaft 2. Because the sliding shaft 2 is hinged with the transmission sleeve shaft, it can rotate a certain angle after receiving the forward force and slide diagonally downward in the slide groove 2. The sliding shaft 2 then drives the transmission connecting plate and the baffle to move diagonally downward to the front side, and moves diagonally downward to the front side and out of the feeding frame, so that the stone can fall out of the feeding frame, so that the stone can be fed out of the feeding frame intermittently in a quantitative manner. When the baffle moves forward and backward, it drives the limit card rod to slide forward and backward in the feeding frame. The limit card rod contacts the four corners of the inner wall of the feeding frame, so that the baffle can move forward and backward smoothly.

[0006] Preferably, the screening device includes a material discharge inclined plate, a lower connecting inclined plate, and a screening mesh plate, the material discharge inclined plate is fixedly connected to the front side of the feed box, the lower connecting inclined plate is fixedly connected to the front side of the material discharge inclined plate, the screening mesh plate is slidably connected to the upper surface of the lower connecting inclined plate, the screening device also includes an upper connecting inclined plate, a second connecting piece, an elastic telescopic rod, an abutting inclined rod, and a discharge frame, the upper connecting inclined plate is fixedly connected to the front side of the material discharge inclined plate, the second connecting piece is fixedly connected to both sides of the inner surface of the material discharge inclined plate, the elastic telescopic rod is fixedly connected to the front side of the material discharge inclined plate, the The fixing is connected to the front side of the second connecting member, the abutting inclined rod is fixedly connected to the rear end of the limiting clamp rod, the discharging frame is fixedly connected to the front side of the feeding box, the lower material inclined plate is fixedly connected to the inner wall of the feeding frame, the lower connecting inclined plate is fixedly connected to both sides of the inner wall of the feeding frame, the screening mesh plate is slidably connected to both sides of the inner wall of the feeding frame, the upper connecting inclined plate is fixedly connected to both sides of the inner wall of the feeding frame, the rear side of the screening mesh plate is fixedly connected to the front end of the elastic telescopic rod, the discharging frame is fixedly connected to the lower surface of the feeding frame, the screening mesh plate and The lower surface of the upper connecting inclined plate is slidably connected. When the stone falls from the feed box into the feed frame, it is blocked by the lower material inclined plate. Then the stone falls onto the screening mesh plate through the lower connecting inclined plate and the upper connecting inclined plate. The stones with smaller particle sizes that can be used fall from the screening mesh plate into the feed frame, while the stones with larger particle sizes cannot pass through the screening mesh plate, thus avoiding the mixing of stones of different particle sizes and making them difficult to use, and improving the efficiency of stone use. When the hydraulic rod drives the receiving plate to rise, the stones with larger particle sizes blocked by the screening mesh plate roll to the bottom of the feed box And it is discharged through the discharge frame, and at this time the baffle drives the limit card rod to move backward, and the limit card rod drives the resistance inclined rod to move backward, the resistance inclined rod contacts the screening mesh plate and pushes the screening mesh plate backward, and when the screening mesh plate moves backward, the large-size stone stuck on the lower connecting inclined plate is pushed to the bottom of the feed box; when the resistance inclined rod moves forward, the screening mesh plate loses the resistance of the resistance inclined rod, and the elastic resetting effect of the elastic telescopic rod drives the screening mesh plate to move forward, and the elastic force of the elastic telescopic rod can pop out the stone stuck on the screening mesh plate.

[0007] Preferably, the dust isolation device includes an isolation mesh plate, a material receiving box, and a box cover, the isolation mesh plate is fixedly connected to the inner surface of the bottom of the feeding frame, the material receiving box is fixedly connected to the lower surface of the feeding frame, the box cover and the front end of the material receiving box are hinged, the dust isolation device also includes a slide groove three, a connecting block, a connecting rod, a roller brush, and a partition, the slide groove three is opened at the bottom of the feeding frame, the connecting block is fixedly connected to the lower surface of the limiting card rod, the connecting rod is fixedly connected to the side of the connecting block close to the isolation mesh plate, the roller brush is rotatably connected to the circumferential surface of the connecting rod, the partition is fixedly connected to the upper and lower sides of the inner wall of the feeding frame, the lower surface of the material receiving box is fixedly connected to the support column, the material receiving box is fixedly connected to the front side of the discharge frame, the connecting block is slidably connected to the inner surface of the slide groove three, the roller brush and The lower surfaces of the isolation mesh plates are in contact with each other, and the limit rod and the partition are in contact with each other on the side away from the isolation mesh plates. When the stone rolls forward in the feeding frame, the dust adhered to the surface of the stone falls from the isolation mesh plates into the receiving box through the centrifugal force and gravity generated during rolling. When the stone is transported, the box cover is opened to clean up the dust in the receiving box, which is convenient for the next dust collection to prevent dust accumulation and improve the isolation effect. When the limit rod moves back and forth, it drives the connecting block to slide back and forth in the slide groove three, and the connecting block drives the connecting rod to move back and forth, and the connecting rod drives the roller brush to move back and forth. During the reciprocating movement of the roller brush, it contacts the isolation mesh plate and generates friction, so that the roller brush wipes off the dust adhered to the isolation mesh plate, and the friction causes the roller brush to rotate along the connecting rod.

[0008] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0009] 1. The quantitative feeding device for building construction uses a laser distance sensor to measure the distance when the receiving plate drops to a certain position. When the distance between the receiving plate and the laser distance sensor reaches the set value, it means that the amount of stone entering the feed box has reached a certain amount. The laser distance sensor transmits a signal to the hydraulic rod. After receiving the signal, the hydraulic rod slowly rises, driving the receiving plate to slowly rise, and finally blocks the feed box to prevent the stone from entering the feed box, so that the amount of stone feed can be accurately controlled, and the baffle moves out of the feed frame, so that the stone is quantitatively and intermittently fed out of the feed frame to avoid continuous feeding of the stone and thus failing to achieve the quantitative effect.

[0010] 2. The quantitative feeding device for construction uses stones to fall onto the screening mesh plate. The stones with smaller particle sizes that can be used fall from the screening mesh plate into the feeding frame, while the stones with larger particle sizes cannot pass through the screening mesh plate, thus avoiding the mixing of stones of different particle sizes and making them difficult to use, thereby improving the efficiency of stone use. When the screening mesh plate moves backward, the large-particle-size stones stuck on the lower connecting inclined plate are pushed to the bottom of the feed box to prevent the accumulation of large-particle-size stones, thus facilitating the next screening. The elastic force of the elastic telescopic rod can eject the stones stuck on the screening mesh plate, thus avoiding the screening mesh plate from being stuck and improving the screening efficiency.

[0011] 3. The quantitative feeding device for construction, the dust adhered to the surface of the stone falls from the isolation mesh into the receiving box. After the dust is reduced, it is more convenient for the workers to receive and use the stone, and at the same time, the dust is prevented from entering the air and affecting the health of the workers. The roller brush rotates along the connecting rod, thereby improving the contact efficiency and friction between the roller brush and the isolation mesh, and then the dust can be wiped off more quickly to prevent the isolation mesh from being blocked, improve the efficiency of dust falling, and avoid some dust from failing to fall through the isolation mesh and re-adhering to the stone, thereby improving the isolation effect.

When the distance between the receiving plate 7 and the laser distance sensor 3 reaches a set value, it indicates that the amount of stone entering the feed box 1 has reached a certain amount. The laser distance sensor 3 transmits a signal to the hydraulic rod 4. After receiving the signal, the hydraulic rod 4 slowly rises, driving the receiving plate 7 to slowly rise, and finally blocks the feed box 1 to prevent the stone from entering the feed box 1, thereby accurately controlling the amount of stone feed. A screening device 8 for screening materials is provided on the front side of the feed box 1. A screen device 8 for screening materials is provided on the front side of the feed box 1. A screen device 8 for removing dust adhering to the material is provided on the front side of the feed box 1. The dust isolation device 9 for isolation is provided, the receiving plate 7 is slidably connected to the inner wall of the feed box 1, the bottom end of the spring buffer column 71 is fixedly connected to the bottom surface of the inner wall of the feed box 1, the sliding shaft 73 is slidably connected to the inner surface of the slide groove 5, the sliding shaft 73 is slidably connected to the inner surface of the inclined groove transmission frame 76, the transmission bent rod 77 is slidably connected to the inner surface of the support member 74, the sliding shaft 2 710 is hinged to the inner surface of the transmission sleeve shaft 78, the limit clamping rod 713 is slidably connected to the inner surface of the feeding frame 6, and the baffle 712 moves out of the feeding frame 6, so that the stone is quantitatively and intermittently fed out of the feeding frame 6, to avoid the stone being continuously fed out of the feeding frame 6 and thus failing to achieve the quantitative effect.

[0025] Working principle: Put the stone into the feed box 1, and the stone falls onto the receiving plate 7 in the feed box 1. The receiving plate 7 moves downward under the influence of the weight of the stone, and drives the spring buffer column 71 to contract. The elastic effect of the spring buffer column 71 buffers the receiving plate 7, so that the receiving plate 7 can fall smoothly. When the receiving plate 7 falls smoothly to a certain position, the laser distance sensor 3 measures the distance. When the distance between the receiving plate 7 and the laser distance sensor 3 reaches the set value, it means that the stone entering the feed box 1 has reached a certain quantity. At this time, the stone falls from the receiving plate 7 into the feed box. Frame 6, and then the laser ranging sensor 3 transmits a signal to the hydraulic rod 4. After receiving the signal, the hydraulic rod 4 starts and holds the receiving plate 7 to prevent excess stone from entering the feeding frame 6 through the receiving plate 7. In the process of the stone entering the feeding frame 6, the hydraulic rod 4 slowly rises, driving the receiving plate 7 to slowly rise and finally blocks the feed box 1 to prevent the stone from entering the feed box 1, so that the feeding amount of the stone can be accurately controlled. The stone entering the feeding frame 6 rolls forward through the inclined surface of the feeding frame 6 and then stops after being blocked by the baffle 712. Then the hydraulic rod 4 drives the receiving plate 7 to descend, and the receiving plate 7 drives the connecting member 1 72 to descend, and the connecting member 1 72 drives the sliding shaft 1 73 to slide downward in the sliding groove 1 5. When the sliding shaft 1 73 slides downward, it is driven to move forward by the guide of the inclined groove in the inclined groove transmission frame 76. The inclined groove transmission frame 76 drives the supporting slide bar 75 and the transmission crank rod 77 to slide forward in the supporting member 74. The transmission crank rod 77 drives the transmission sleeve shaft 78 to move forward. The forward force of the transmission sleeve shaft 78 is transmitted to the sliding shaft 2 710. Because the sliding shaft 2 710 is hinged with the transmission sleeve shaft 78, it can rotate to a certain angle after receiving the forward force and move on the sliding shaft. The second sliding shaft 710 then drives the transmission connecting plate 711 and the baffle plate 712 to move obliquely downward to the front side, and then moves out of the feeding frame 6 obliquely downward to the front side, so that the stone can fall out of the feeding frame 6, thereby enabling the stone to be quantitatively and intermittently fed out of the feeding frame 6, thereby preventing the stone from being continuously fed out of the feeding frame 6 and thus failing to achieve a quantitative effect. When the baffle plate 712 moves back and forth, it drives the limit clamping rod 713 to slide back and forth in the feeding frame 6, and the limit clamping rod 713 contacts the four corners of the inner wall of the feeding frame 6, thereby enabling the baffle plate 712 to move smoothly back and forth.

Stones fall onto the screening mesh plate 83, and stones with smaller particle sizes that can be used fall into the feeding frame 6 from the screening mesh plate 83, while stones with larger particle sizes cannot pass through the screening mesh plate 83, thereby avoiding the mixing of stones of different particle sizes and making them difficult to use, thereby improving the efficiency of stone use. The screening device 8 also includes an upper connecting inclined plate 84, a second connecting piece 85, an elastic telescopic rod 86, an abutting inclined rod 87, and a discharge frame 88.

The stone with smaller particle size that can be used falls from the screening mesh plate 83 into the feed frame 6, while the stone with larger particle size cannot pass through the screening mesh plate 83, thus avoiding the mixing of stones of different particle sizes and making them difficult to use, thereby improving the efficiency of stone use. When the hydraulic rod 4 drives the receiving plate 7 to rise, the stone with larger particle size blocked by the screening mesh plate 83 rolls to the bottom of the feed box 1 and is discharged from the device through the discharge frame 88, and at this time, the baffle 712 drives the limit clamping rod 713 to move backward The limit clamping rod 713 then drives the oblique resistance rod 87 to move backward, and the oblique resistance rod 87 contacts the screening mesh plate 83 and pushes the screening mesh plate 83 backward. When the screening mesh plate 83 moves backward, the large-grained stones stuck on the lower connecting inclined plate 82 are pushed to the bottom of the feed box 1 to prevent the large-grained stones from accumulating and facilitate the next screening. When the oblique resistance rod 87 moves forward, the screening mesh plate 83 loses the resistance of the oblique resistance rod 87, and the elastic reset effect of the elastic telescopic rod 86 drives the screening mesh plate 83 to move forward, and the elastic force of the elastic telescopic rod 86 can pop out the stones stuck on the screening mesh plate 83, thereby avoiding the screening mesh plate 83 from being stuck and improving the screening efficiency.
