Description

Technical Field

[0001] This disclosure specifically discloses a mortar processing technology field, specifically relating to a dust-proof and sealed mortar powder quantitative dispensing device. Background Technology

[0002] Mortar is a binding material used in bricklaying. It is made by mixing sand and cementitious materials with water in a certain proportion. It is also called mortar. When the powder is added for processing, it is usually mixed by a mixer on a large construction site.

[0003] According to application number 202221206226.3, a mortar powder quantitative dispensing device is disclosed, including an adjusting seat, a rotating component, a storage component, and a dispensing component. The adjusting seat includes a fixed ring and a rotating ring rotatably mounted on the fixed ring. The storage component has a spherical structure and is mounted inside the rotating ring via the rotating component. The rotating shaft of the rotating component passes laterally through the center of the storage component, and a storage trough is provided at the top of the storage component. The dispensing component is located at the top of the rotating ring, and multiple dispensing troughs are arranged circumferentially inside the dispensing component. When the rotating component is running, the storage trough on the storage component rotates to the range of a dispensing trough. After loading powder, it rotates to face the fixed ring, thereby pouring the powder in its storage trough to a predetermined position.

[0004] Existing mortar powder dispensing devices lack dustproof features, resulting in significant dust generation during mixing, which impacts worker health and reduces powder concentration. Furthermore, existing dispensing devices cannot reduce the feed inlet size. Therefore, we propose a dustproof, sealed mortar powder dispensing device. Summary of the Invention

[0013] The second motor is started via the metering device, storage tank, and dispensing port. The second motor drives the turntable to rotate, which in turn drives the fixed shaft to make a circular motion. The fixed shaft drives the movable rod to swing. The movable rod is movably connected to the connecting rod. Through the limiting frame, the swinging of the movable rod drives the connecting rod to reciprocate. The connecting rod drives the baffle plate to move back and forth, thereby opening the through hole. The through hole can send the mortar powder into the inner cavity of the mixing tank, and then the metered dispensing is completed.

[0014] By connecting the shaft, dustproof plate, handle, storage bin, and feeding port, the dust generated during powder feeding is prevented from flying out through the top of the storage bin and the inclined feeding port. By pushing the handle, the dustproof plate is installed on the top of the feeding port, effectively blocking dust from flying and improving the physical and mental health of the staff.

[0023] As mentioned in the background section, existing mortar powder feeding devices do not have dustproof devices when feeding mortar powder, which causes the mixer to generate a lot of dust during mixing, affecting the health of workers and reducing the concentration of powder. In addition, existing fixed feeding devices cannot feed material by reducing the feed opening. This disclosure proposes a structure with dustproof and reduced feed opening. Example 1

[0024] Please see Figure 1A dust-proof and sealed mortar powder quantitative dispensing device includes a mixing tank 1. In order to facilitate use and removal of the mixed mortar, a support frame 2 is provided on the lower end face of the mixing tank 1, and the support frame 2 is welded to the lower end face of the mixing tank 1 to effectively ensure the stability of the mixing tank 1. In order to facilitate material removal, a discharge port 8 is fixedly connected in the middle of the lower end face of the mixing tank 1.

[0025] Please see Figure 1 To facilitate the feeding of sand or water, a feed inlet 3 is fixedly connected to the left side of the upper end face of the mixing tank 1. To prevent dust, a dustproof device is installed on the upper end face of the feed inlet 3. A first motor 4 is fixedly connected to the center of the upper end face of the mixing tank 1, and the motor shaft of the first motor 4 extends through the inner cavity of the mixing tank 1 and is fixedly connected to a rotating shaft 9. To mix the mortar powder, a mixing rod 10 is evenly fixedly connected to the outer wall of the rotating shaft 9. To achieve quantitative feeding of powder and reduce manual error, a storage tank 5 is fixedly connected to the right side of the upper end face of the mixing tank 1. To facilitate feeding, a feeding port 6 is connected to the upper part of the outer wall of the storage tank 5. The feeding port 6 is inclined to facilitate feeding. To facilitate fixed feeding, a metering device 7 is installed at the front right side of the upper end face of the mixing tank 1.

[0026] Please see Figure 2 To accurately dispense powder, a metering device 7 is constructed using a baffle plate 71, a groove 72, a connecting rod 73, a limiting frame 74, a movable rod 75, a fixed shaft 76, a turntable 77, and a second motor 78. A groove 72 is provided on the right side of the upper end face of the mixing tank 1. A baffle plate 71 is installed inside the groove 72. A second motor 78 is fixedly connected to the front side of the outer wall of the mixing tank 1. A turntable 77 is fixedly connected to the upper end face of the motor shaft of the second motor 78. A fixed shaft 76 is fixedly connected to the outer side of the upper end face of the turntable 77. A movable rod 75 is sleeved on the outside of the fixed shaft 76. A connecting rod 73 is movably connected to the end of the movable rod 75. The end of the connecting rod 73 is fixedly connected to the front end face of the baffle plate 71. To ensure that the connecting rod 73 can move stably back and forth, a limiting frame 74 is sleeved in the middle of the outer wall of the connecting rod 73. The limiting frame 74 is fixedly connected to the bottom end face of the inner cavity of the groove 72, effectively ensuring the stability of the connecting rod 73.

[0027] Please see Figure 2 In order to ensure the normal addition of mortar powder, an inlet 11 is provided in the middle of the bottom end face of the inner cavity of the groove 72, and the inlet 11 is located directly below the storage tank 5. A through hole is provided on the lower end face of the storage tank 5, and the diameter of the through hole is smaller than the diameter of the inlet 11.

[0028] Please see Figure 2 To ensure that the baffle plate 71 does not leak material or shift, the thickness of the baffle plate 71 matches the depth of the groove 72, and the width of the baffle plate 71 matches the width of the inner cavity of the groove 72, so as to ensure that the baffle plate 71 can move back and forth normally.

[0029] Please see Figure 2 In order to ensure that the swing of the movable rod 75 can drive the reciprocating motion of the connecting rod 73, a connecting shaft is provided at the end of the movable rod 75 near the connecting rod 73, and the connecting rod 73 is sleeved on the outside of the connecting shaft. At the same time, a limit plate is fixedly connected to the upper end face of the fixed shaft 76 to effectively prevent the movable rod 75 from jumping off. Example 2

[0030] Please see Figure 4 To prevent dust from being generated when mixing begins or when adding mortar powder, a dustproof device is formed by connecting shaft 12, dustproof plate 13 and handle 14. Dustproof plate 13 is installed on the upper end face of feed inlet 3. Connecting shaft 12 is fixedly connected to the left side of the outer wall of dustproof plate 13, and connecting shaft 12 is sleeved in the opening on the left side of the outer wall of feed inlet 3 to ensure that dustproof plate 13 swings normally. To facilitate swinging, handle 14 is fixedly connected to both the front and rear sides of the outer wall of dustproof plate 13.

[0031] Working principle: When processing concrete, push handle 14 to move dust cover 14 to one side, then pour the required sand and gravel into feed inlet 3. After feeding, push handle 14 to ensure dust cover 14 covers the upper surface of feed inlet 3, and feed the required mortar powder into the inner cavity of storage tank 5 through feed port 6. Using external power, start second motor 78. Second motor 78 drives turntable 77 to rotate, and turntable 77 drives fixed shaft 76 to perform circular motion. 76 drives the movable rod 75 to swing, and the movable rod 75 is movably connected to the connecting rod 73. Through the limiting frame 74, the swing of the movable rod 75 drives the connecting rod 73 to reciprocate. The connecting rod 73 drives the baffle plate 71 to move back and forth, thereby opening the through hole. The through hole can send the mortar powder into the inner cavity of the mixing tank 1. After that, it is quantitatively added. The baffle plate 71 is reset and blocks the through hole. At this time, the dustproof plate 13 can block the dust of the powder and effectively protect the physical and mental health of the workers.
