Description

Technical Field

[0001] This utility model is a dry mortar mixing and feeding device, belonging to the technical field of dry mortar mixing equipment. Background Technology

[0002] Dry mortar refers to a granular or powdery material made by physically mixing aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) in a certain proportion after drying and screening. It is transported to the construction site in bagged or bulk form and can be used directly after being mixed with water. It is also known as dry mortar powder, dry-mixed mortar, or dry-mixed powder. Some building adhesives also belong to this category. Dry mortar plays a role in bonding, padding, protection, and decoration in the construction industry by applying thin layers. It is widely used in building and decoration projects. During the production process of dry mortar, mixing and feeding equipment is required to fully mix it.

[0003] Publication number CN220179717U mentions a dry mortar mixing and feeding device. During use, this device, equipped with a stirring rod and a crushing rod, uses the rotating stirring rod in conjunction with the crushing rod to crush and pulverize clumps of dry mortar. This further pulverizes the clumps of dry mortar in the feeding hopper, preventing clumps from forming after prolonged storage and affecting later use. However, some clumps of dry mortar adhere to the side wall of the feeding hopper. The current device, with only a stirring rod and a crushing rod, cannot clean the clumps adhering to the side wall of the feeding hopper. Therefore, there is an urgent need for a dry mortar mixing and feeding device to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a dry mortar mixing and feeding device to solve the problems mentioned in the background art. This utility model designs a rotating scraper structure that can scrape and clean the dry mortar adhering to the side wall of the feeding funnel, and can also simultaneously disperse the dry mortar in the feeding funnel evenly. Moreover, the overall structure is relatively simple, and it is also convenient to disassemble, repair or replace the scraper structure that has been used for a long time.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a dry mortar mixing and feeding device, comprising a feeding funnel, a scraper, and spiral blades. A horizontal frame is horizontally fixed at the upper end of the feeding funnel. A mixing motor is installed in the middle of the upper end of the horizontal frame. A mixing shaft is longitudinally arranged at the shaft end of the mixing motor. Multiple mixing blades are symmetrically fixed at the left and right ends of the mixing shaft. Each of the four mixing blades has a spring groove at its outer end, and a return spring is installed in each of the four spring grooves. The four return springs are longitudinally fixed relative to each other on the outer side. The device includes movable locking tabs. Two scrapers are provided, each with a silicone scraper blade fixed to its outer end. Trapezoidal blocks are welded to the lower inner sides of both scrapers. Positioning rods are horizontally fixed to the inner sides of the two trapezoidal blocks and the upper inner sides of the two scrapers. Four reset springs and four movable locking tabs are respectively sleeved on the outside of the four positioning rods. A conical shell is longitudinally connected to the lower end of the feeding hopper via a connecting flange. A servo motor is installed at the lower end of the conical shell, and spiral blades are longitudinally installed inside the conical shell, with the lower ends of the spiral blades connected to the servo motor for transmission.

[0006] Furthermore, the lower end of the feeding funnel is equipped with longitudinal support legs on all four sides, the rear end of the feeding funnel is horizontally fitted with a horizontal cover, and the front left side of the feeding funnel is equipped with easy-maintenance covers by bolts at both the upper and lower positions.

[0007] Furthermore, each of the four spring slots has a push-pull slot at its lower end, and the four movable latching pieces are slidably located within the four push-pull slots respectively.

[0008] Furthermore, the two silicone scrapers slide against the left and right ends of the inner wall of the feeding funnel, respectively.

[0009] Furthermore, each of the four movable snap-fit ​​pieces has a retaining ring fixed to its lower outer side.

[0010] Furthermore, a discharge pipe is installed at an angle on the right end of the conical shell.

[0011] The beneficial effects of this utility model: This utility model provides a dry mortar mixing and feeding device. Because it incorporates a mixing motor, mixing shaft, mixing blades, return spring, positioning rod, movable locking piece, buckle, scraper, silicone scraper, trapezoidal block, and easy-to-maintain cover, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The design of a rotating scraper structure can scrape and clean the dry mortar adhering to the side wall of the feeding hopper, and can also simultaneously and evenly disperse the dry mortar inside the feeding hopper. Furthermore, the overall structure is relatively simple, and it is convenient to disassemble, repair, or replace the scraper structure after long-term use. The use of a horizontal baffle, connecting flange, servo motor, spiral blades, conical shell, and discharge pipe facilitates the even conveying of dry mortar. Attached Figure Description

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: a dry mortar mixing and feeding device, including a feeding funnel 1, scrapers 12, and spiral blades 19. A horizontal frame 2 is horizontally fixed at the upper end of the feeding funnel 1. A mixing motor 3 is installed in the middle of the upper end of the horizontal frame 2. A mixing shaft 4 is longitudinally arranged at the shaft end of the mixing motor 3. Multiple mixing blades 5 are symmetrically fixed at the left and right ends of the mixing shaft 4. Each of the four mixing blades 5 has a spring groove 6 at its outer end, and a return spring 8 is installed in each of the four spring grooves 6. Movable locking pieces 10 are longitudinally fixed to the outer sides of each of the four return springs 8. Two scrapers 12 are provided, and silicone scraper blades 13 are fixed to the outer ends of both scrapers 12. Two scrapers 12 are welded to their inner lower ends with trapezoidal blocks 14. Positioning rods 9 are horizontally fixed to the inner sides of the two trapezoidal blocks 14 and the inner upper ends of the two scrapers 12. Four reset springs 8 and four movable snap-fit ​​pieces 10 are respectively sleeved on the outside of the four positioning rods 9. The lower end of the feeding funnel 1 is longitudinally connected to a conical shell 20 through a connecting flange 17. A servo motor 18 is installed at the lower end of the conical shell 20. Spiral blades 19 are longitudinally installed inside the conical shell 20, and the lower end of the spiral blades 19 is connected to the servo motor 18 for transmission. This design solves the problem that the original device, which only has a stirring rod and a crushing rod, cannot clean the dry mortar adhering to the side wall of the feeding funnel.

[0019] As the first embodiment of this utility model: Support legs are longitudinally installed around the lower end of the feeding funnel 1. A horizontal cover 16 is horizontally secured to the lower rear side of the feeding funnel 1. Easy-care covers 15 are bolted to the upper and lower left sides of the front end of the feeding funnel 1. The added horizontal cover 16 can seal and block the lower end of the feeding funnel 1, while the easy-care cover 15 facilitates opening the front end of the feeding funnel 1 to easily fasten the buckle 11. Push-pull slots 7 are opened at the lower ends of the four spring grooves 6. Four movable locking pieces 10 slide within the four push-pull slots 7 respectively. The addition of four movable locking pieces 10 allows workers to easily pull the movable locking pieces 10 within the push-pull slots 7.

[0020] Two silicone scrapers 13 slide against the left and right ends of the inner wall of the feeding hopper 1, respectively. By having these two silicone scrapers slide against the left and right ends of the inner wall of the feeding hopper 1, the dry mortar on the inner wall of the feeding hopper 1 can be scraped off during rotation. Each of the four movable locking tabs 10 has a retaining ring 11 fixed to its lower outer side. These retaining rings 11 facilitate the pulling of the movable locking tabs 10. A discharge pipe 21 is installed at an angle on the right end of the conical shell 20. This discharge pipe 21 facilitates the discharge of dry mortar from the conical shell 20 by the rotating spiral blades 19.

[0021] As a second embodiment of this utility model: In actual use, the stirring motor 3 is started, which drives the stirring shaft 4, multiple stirring blades 5, two scrapers 12, and two silicone scrapers 13 to rotate, thereby rotating and dispersing the dry mortar in the feeding funnel 1. At the same time, the rotating silicone scrapers 13 can rotate and scrape off the dry mortar on the inner wall of the feeding funnel 1. After completion, the horizontal cover 16 is pulled back to make the feeding funnel 1 communicate with the conical shell 20, and the dry mortar in the feeding funnel 1 will also fall into the conical shell 20. The servo motor 18 is started, which drives the spiral blades 19 to rotate. The rotating spiral blades 19 can carry the dry mortar in the conical shell 20 and discharge it through the discharge pipe 21; wait for the scrapers 12 and silicone scrapers 13 to rotate. 3. After prolonged use (taking the removal of a single scraper 12 and silicone scraper 13 on the left side as an example), use an external wrench to remove multiple bolts, then remove the two maintenance covers 15. The worker can then pass their hand through the slots of the two maintenance covers 15, hook the two retaining rings 11 and pull to the right. The two retaining rings 11 will drive the two movable locking pieces 10 to move to the right in the two push-pull slots 7. The two movable locking pieces 10 will then move to the right outside the two positioning rods 9 and compress the two return springs 8 to the right until the two movable locking pieces 10 are completely removed from outside the two positioning rods 9. Then, pull up the scraper 12, and the two positioning rods 9 will move upward from the two spring slots 6. Finally, pull the scraper 12 and silicone scraper 13 out from the upper left side of the discharge funnel 1 for maintenance or replacement.
