Description

Technical Field

[0001] This utility model relates to the field of building material discharging technology, specifically a quantitative discharging mechanism for building materials. Background Technology

[0002] In construction engineering, the transportation and uniform discharge of raw materials such as cement are crucial to ensuring project quality. Whether it is concrete mixing, wall construction, or floor leveling, the accuracy of the raw material proportions directly affects core indicators such as component strength and flatness, while the smoothness of material discharge determines construction efficiency.

[0003] Traditional raw material discharge devices often employ a screw feeder combined with a discharge valve. By adjusting the rotation speed of the screw blades, the material conveying rate per unit time is controlled, achieving a preliminary quantitative discharge function. However, due to the inherent properties of building materials—their tendency to absorb moisture and clump—especially in high-humidity environments, materials easily agglomerate or clump at the discharge port during transport, leading to poor discharge or even complete blockage, severely impacting the stability of continuous operation.

[0004] Therefore, we propose a quantitative dispensing mechanism for building materials to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model: The purpose of this utility model is to provide a quantitative dispensing mechanism for building materials to solve the problems currently existing in the market as mentioned in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: a quantitative discharging mechanism for building materials, including a frame, a screw feeder installed at the upper end of the frame, a feed hopper installed at the upper rear end of the screw feeder, and a discharge port opened at the front side of the screw feeder, the discharge port being connected to a discharge pipe, and a base plate being rotatably installed at the bottom of the discharge pipe. The discharge pipe is fixed with mounting brackets on both the front and rear sides, and a drive assembly and a pressing assembly are installed between the two mounting brackets. The drive assembly is used to drive the pressing assembly to move back and forth in the vertical direction. During the back and forth movement, the pressing assembly drives the base plate to rotate back and forth around its axis to break up the material discharged from the discharge port.

[0007] Furthermore, two fixing rods are symmetrically fixed between the two mounting brackets, and a sliding groove is provided on the side of the fixing rods near the center of the mounting bracket.

[0008] The above technical solutions can increase connection stability.

[0009] Furthermore, the drive assembly includes two turntables, a rotating roller, and a reduction motor; The two turntables are symmetrically mounted on one side of two mounting brackets close to each other via bearings, and the two ends of the roller are rotatably connected to the two turntables respectively; The geared motor is mounted on a mounting bracket located on the rear side via a motor mount, and the output end of the geared motor is connected via a key to drive the turntable located on the rear side to rotate synchronously.

[0010] The above technical solution enables the geared motor to drive the rotating roller to rotate around the center of the turntable after it starts.

[0011] Furthermore, the top-pressing assembly includes two support rods, a movable frame, a through groove, and a lifting roller; The two support rods are symmetrically installed on the front and rear sides of the upper end of the movable frame, and the two ends of the lifting roller are respectively rotatably connected to the upper ends of the two support rods; The movable frame has a through groove running from front to back in the middle, and the rotating roller is inserted into the through groove and slides in contact with its inner wall.

[0012] The above technical solution allows the roller to slide within the groove when it rotates, thereby applying a force that moves up and down to the top pressing assembly.

[0013] Furthermore, the through groove is a straight through hole, and the rotating roller is eccentrically set with respect to the rotating shaft of the turntable, so that when the turntable rotates, the rotating roller slides in the through groove to push the movable frame to achieve up-and-down reciprocating motion.

[0014] The above technical solution enables the movable frame to move up and down when the turntable rotates.

[0015] Furthermore, slide bars are fixed on both the left and right sides of the support rod. The slide bars are slidably embedded in the slide grooves on the mounting frame, forming a guiding and limiting structure for the vertical movement of the movable frame.

[0016] The above technical solution enables stable movement through the cooperation of the slide rail and the slide bar.

[0017] Furthermore, the front and rear edges and the upper right edge of the base plate are all attached to the inner wall of the discharge pipe.

[0018] The above technical solutions improve the sealing effect and prevent material leakage.

[0019] 3. Beneficial effects: Compared with the prior art, the building material quantitative discharging mechanism of this utility model, through the cooperation of the drive component and the top pressing component, drives the bottom plate to reciprocate and beat the output building materials, ensuring that the materials are in a loose state and guaranteeing the subsequent use effect of the building materials. The specific details are as follows: Building materials, such as cement, are fed into the hopper. The screw feeder is then activated. Driven by a motor, the internal screw blades rotate, propelling the material forward in a measured quantity. The material is then discharged through the outlet and discharge pipe. Simultaneously, the geared motor is activated. Its output, connected via a key, drives the rear turntable to rotate. Because the roller and turntable shafts are eccentrically positioned, the roller slides along the groove wall within the movable frame during rotation, thus pushing the movable frame to reciprocate vertically. During this process, the sliding strips on both sides of the support rod slide along the fixed rod... Synchronous sliding within the trough provides vertical guidance for the movable frame, preventing deviation and jamming. When the movable frame moves vertically back and forth, it drives the upper support rod and the lifting roller to move up and down synchronously. When the lifting roller hits the bottom plate, the bottom plate rotates upward around its own axis. During the rotation, it beats the lumpy material inside the pipe. When the lifting roller moves downward, the bottom plate resets under its own weight and the pressure of the material inside the pipe. Through continuous reciprocating rotation, the bottom plate continuously breaks up the lumpy material entering the discharge pipe from the discharge port, ensuring that the material is in a loose state and guaranteeing the subsequent use effect of the building materials.

[0026] Please see Figure 1-6 A quantitative discharging mechanism for building materials includes a frame 1, a screw feeder 2 installed at the upper end of the frame 1, a feed hopper 3 installed at the upper rear end of the screw feeder 2, and a discharge port 4 opened at the front side of the screw feeder 2. The discharge port 4 is connected to a discharge pipe 5, and a base plate 6 is rotatably installed at the bottom of the discharge pipe 5. The front and rear edges and the upper right edge of the base plate 6 are all attached to the inner wall of the discharge pipe 5. Building materials, such as cement, are put into the feed hopper 3. The screw feeder 2 is started. The screw feeder 2 is driven by the motor to rotate the internal screw blades. The friction and thrust between the screw blades and the raw materials are used to stably transport the raw materials from the rear end to the front end. The speed of the screw blades is controlled to precisely adjust the amount of raw materials transported per unit time, so as to achieve quantitative transport. The raw materials are finally discharged through the discharge port 4 and discharge pipe 5 on the front side of the screw feeder 2. Mounting brackets 7 are fixed on both the front and rear sides of the discharge pipe 5, and a drive assembly 8 and a pressing assembly 9 are installed between the two mounting brackets 7. The drive assembly 8 drives the pressing assembly 9 to reciprocate in the vertical direction. During the reciprocating movement, the pressing assembly 9 drives the base plate 6 to rotate around its axis to break up the material discharged from the discharge port 4. Two fixing rods 71 ​​are symmetrically fixed between the two mounting brackets 7, and a sliding groove 72 is opened on the side of the fixing rod 71 near the center of the mounting bracket 7. The drive assembly 8 includes two turntables 81, a rotating roller 82, and a geared motor 83. The two turntables 81 are symmetrically mounted on the side of the two mounting brackets 7 close to each other through bearings, and the two ends of the rotating roller 82 are rotatably connected to the two turntables 81 respectively. The geared motor 83 is mounted on the mounting bracket 7 located on the rear side through a motor base, and the output end of the geared motor 83 is connected to the drive via a key. The turntable 81 located at the rear rotates synchronously; the top pressing assembly 9 includes two support rods 91, a movable frame 92, a through groove 93, and a lifting roller 94; the two support rods 91 are symmetrically installed on the front and rear sides of the upper end of the movable frame 92, and the two ends of the lifting roller 94 are respectively rotatably connected to the upper ends of the two support rods 91; a through groove 93 is opened in the middle of the movable frame 92, and the rotating roller 82 is inserted into the through groove 93 and slides in contact with its inner wall; the through groove 93 is a straight through hole, and the rotating roller 82 is eccentrically set with the rotating shaft of the turntable 81, so that when the turntable 81 rotates, the rotating roller 82 slides in the through groove 93 to push the movable frame 92 to achieve up and down reciprocating motion; the left and right sides of the support rods 91 are fixed with slide bars 95, and the slide bars 95 are slidably embedded in the slide grooves 72 on the mounting frame 7, forming a guiding and limiting structure for the vertical movement of the movable frame 92; When the screw feeder 2 starts, the geared motor 83 is also started. The output of the geared motor 83 drives the rear turntable 81 to rotate via a key connection. Since the rotating roller 82 and the rotating shaft of the turntable 81 are eccentrically set, during the rotation of the turntable 81, the rotating roller 82 will slide along the groove wall in the through groove 93 of the movable frame 92, thereby pushing the movable frame 92 to reciprocate in the vertical direction. During this process, the sliding strips 95 on both sides of the support rod 91 slide synchronously in the sliding groove 72 of the fixed rod 71, providing vertical guidance for the movable frame 92 and preventing deviation. When the movable frame 92 moves vertically back and forth, it drives the upper support rod 91 and the lifting roller 94 to move up and down synchronously. When the lifting roller 94 hits the bottom plate 6, the bottom plate 6 rotates upward around its own axis. During the rotation, it beats the lumpy material in the pipe. When the lifting roller 94 moves downward, the bottom plate 6 resets under its own weight and the pressure of the material in the pipe. The bottom plate 6 continuously beats the lumpy material entering the discharge pipe 5 from the discharge port 4 by continuously reciprocating, ensuring that the material is in a loose state and ensuring the subsequent use effect of the building materials.

[0027] Working principle: When using this building material quantitative dispensing mechanism, such as Figure 1-6 As shown, building materials, such as cement, are first fed into the feed hopper 3. The screw feeder 2 is then started, and it steadily conveys the materials from the rear end to the front end. Finally, the materials are discharged from the discharge port 4 and the discharge pipe 5. During the discharge process, the reduction motor 83 drives the rotating roller 82 to rotate through the turntable 81. The rotating roller 82 slides along the wall of the channel 93, pushing the movable frame 92 to reciprocate in the vertical direction. This, in turn, drives the upper support rod 91 and the lifting roller 94 to move up and down synchronously. When the lifting roller 94 hits the bottom plate 6, the bottom plate 6 rotates upward around its own axis. During the rotation, it beats the lumpy materials in the pipe. When the lifting roller 94 moves downward, the bottom plate 6 resets under its own weight and the pressure of the materials in the pipe. The bottom plate 6 continuously beats the lumpy materials entering the discharge pipe 5 from the discharge port 4 by continuously reciprocating, ensuring that the materials are in a loose state and guaranteeing the subsequent use effect of the building materials.
