Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof glue feeding, and more specifically, to a concrete waterproofing agent feeding device. Background Art
[0002] In concrete production, waterproofing agent, as an important additive, plays a vital role in improving the waterproof performance and durability of concrete. However, in actual application, waterproofing agent agglomeration is a common problem. Since waterproofing agents are mostly powdery and have strong hygroscopicity, they can easily absorb moisture in the air during storage and transportation, causing adhesion between powder particles to form lumps of varying sizes. If they are directly mixed without treatment during feeding, the waterproofing agent will be unevenly dispersed, locally excessive or insufficient, seriously affecting the waterproof performance of concrete. In addition, agglomerated waterproofing agents will also block the delivery pipeline, increase the failure rate of equipment, and reduce production efficiency.
[0003] Secondly, most of the existing crushing devices use a motor-driven gear transmission method to crush the agglomerated waterproofing agent through a crushing roller. However, long-term operation will cause gear wear, reduced transmission efficiency, and poor crushing effect. In order to extend the service life of the equipment, the gears need to be lubricated and maintained regularly. However, the existing technology usually uses manual application of lubricating grease, which is not only inefficient but also easy to miss, resulting in increased equipment wear and increased maintenance costs. The low degree of automation also restricts the application and promotion of waterproofing agent feeding devices.
[0004] In addition, there may still be a small amount of incompletely crushed small pieces in the crushed waterproofing agent, which will affect the uniformity of the concrete if directly transported to the mixer. Existing devices usually lack screening treatment for the crushed waterproofing agent and fail to effectively remove the residual lumps, which poses a hidden danger to the subsequent concrete production. At the very least, it affects the workability of the concrete, and at worst, it causes the waterproofing performance to fail to meet the standards, posing a hidden danger to the project quality.

[0016] (III) Beneficial effects
[0017] Compared with the prior art, the utility model provides a concrete waterproofing agent feeding device, which has the following beneficial effects:
[0018] 1. The pulverizing device uses a motor to drive the pulverizing roller to rotate. The lumped waterproofing agent is broken through the cooperation of the pulverizing bin and the pulverizing roller. The high-speed rotation of the pulverizing roller generates strong shear force and impact force, which can effectively destroy the adhesion between the lumps and restore the waterproofing agent to a loose state. At the same time, the reasonable design of the pulverizing bin ensures the full mixing and uniform dispersion of the waterproofing agent during the pulverizing process, avoiding the problem of local excess or deficiency. This efficient and uniform pulverizing method not only improves the utilization rate of the waterproofing agent, but also lays a solid foundation for subsequent concrete production.
[0019] 2. The lubrication mechanism cleverly utilizes the rotation of the driven wheel, and realizes automatic lubrication of the gear through the cooperation of the sealing frame, the push spring and the oil outlet groove. When the driven wheel rotates, the teeth push the sealing frame to make it slide in the limit frame and compress the push spring. At the same time, the oil outlet groove is connected with the oil storage tank. Under the action of centrifugal force, the lubricating oil flows to the gear surface through the oil outlet groove to achieve fixed-point lubrication. When the teeth are separated from the sealing frame, the push spring is reset, the oil outlet groove is no longer connected with the oil storage tank, and the lubricating oil stops flowing out. This automated lubrication method not only reduces manual intervention and improves lubrication efficiency, but also extends the service life of the gear and reduces equipment maintenance costs through fixed-point and quantitative oil supply.
[0020] 3. The screening device is set at the top of the mixer. The crushed waterproofing agent is screened twice through the screening bin and the detachable screening plate. The vibrator drives the screening bin and the screening plate to vibrate at high frequency, so that the waterproofing agent is fully dispersed on the screening plate. Small particles enter the lower bin through the sieve holes, and the residual lumps are separated. The design of the spring and telescopic sleeve reduces the adverse effects of vibration on the mixer. After the dual treatment of crushing and screening, the waterproofing agent entering the mixer has uniform particle size and excellent quality, which provides a reliable guarantee for the production of high-performance concrete.

[0034] In this embodiment, when the device needs to be used to load the waterproofing agent, the waterproofing agent is first put into the crushing bin 6, and the motor 3 is turned on at the same time. The motor 3 drives the corresponding driven wheel 5 to rotate through the driving wheel 4 connected to the output end, thereby driving other driven wheels 5 to rotate, and then the driven wheel 5 will drive the crushing roller 7 to rotate, thereby crushing the agglomerated waterproofing agent, and the crushed waterproofing agent will enter the loading bin 2 connected below the crushing bin 6, and then the driving assembly 15 is turned on, and the driving assembly 15 drives the spiral loading rack 14 to rotate, thereby transporting the crushed waterproofing agent in the loading bin 2.

[0040] More specifically, when the waterproofing agent in the upper silo 2 is transported to the top of the mixer 1, it will fall on the screening plate 18 arranged on the inner side of the screening silo 17, and then the vibrators 20 installed on both sides of the screening silo 17 will be turned on synchronously. The vibrators 20 drive the screening silo 17 and the screening plate 18 to vibrate, thereby realizing the screening of the waterproofing agent and ensuring the mixing quality. The setting of the spring 21 can reduce the impact of vibration on the mixer 1 and prevent hard interference.

[0041] In summary, when the overall equipment is in use or running: when the equipment needs to be used to load the waterproofing agent, the waterproofing agent is first put into the crushing bin 6, and the motor 3 is turned on at the same time.
