Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a special mixing device for the production of dry powder mortar. Background Technology

[0002] Dry mortar refers to a granular or powdery material made by physically mixing dried and screened aggregates (such as quartz sand), inorganic cementitious materials (such as cement), and additives (such as polymers) in a certain proportion. It is transported to the construction site in bagged or bulk form and can be used directly after mixing with water. It is also known as dry mortar powder, dry-mixed mortar, or dry-mix powder. Some building adhesives also fall into this category. After mixing dry mortar in a mixer, particles such as quartz sand easily adhere to the inside of the mixer once they come into contact with water or other media. Therefore, the mixer needs to be cleaned after discharge to prevent it from solidifying inside and causing inconvenience in subsequent use. However, since general cleaning only involves rinsing with water, it is difficult to completely remove material adhering to the crevices behind the mixing blades, especially in complex mixer structures. Therefore, a device is needed to conveniently clean the dry mortar after each mixing and discharge. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a dedicated mixing device for dry mortar production, which facilitates the cleaning of dry mortar adhering to its interior.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a special mixing device for dry mortar production, comprising a support frame, a roller fixedly connected to the upper side of the outer wall of the support frame, a motor fixedly connected to the outer side of the support frame, a friction wheel fixedly connected to the output end of the motor, a transmission wheel contacting the outer wall of the friction wheel, the outer wall of the transmission wheel contacting the roller, a drum fixedly connected to the inner wall of the transmission wheel, the front side of the drum being open, a sealing plate fixedly connected to the rear side of the drum, the sealing plate sealing the rear side of the drum, a mixing blade fixedly connected to the inner wall of the drum, the mixing blade being spirally arranged inside the drum, and a cleaning mechanism being provided in the middle of the mixing blade.

[0005] Preferably, the cleaning mechanism includes a fixed tube located in the middle of the drum. The outer wall of the fixed tube is rotatably connected to the outer wall of the stirring blade via a bearing. The rear side of the fixed tube is fixedly connected to the front side of the sealing plate. The front end of the fixed tube is rotatably connected to a water inlet pipe via a bearing. The fixed tube has several water outlet holes, which are evenly distributed in a ring on the fixed tube. A one-way valve is installed inside each water outlet hole. The input end of the one-way valve is located on one side inside the fixed tube. A knocking mechanism is installed inside the fixed tube.

[0006] Preferably, the striking mechanism includes a fixed rod located inside the fixed tube. The rear end of the fixed rod is connected to the front side of the sealing plate via a ratchet structure. The ratchet structure at the connection between the fixed rod and the sealing plate can only support the fixed rod to rotate clockwise. A vibration mechanism is provided on the lower side of the outer wall of the fixed rod. A threaded plate is fixedly connected to the inner wall of the water outlet. The threaded plate is arranged in a spiral pattern inside the water outlet. A stop block is fixedly connected to the inner wall of the water outlet.

[0007] Preferably, the vibration mechanism includes a hollow tube located inside a fixed tube. The upper outer wall of the hollow tube is fixedly connected to the outer wall of the fixed rod. A spring is fixedly connected to the inner wall of the hollow tube. Springs are provided on all four inner walls of the hollow tube. A connecting rod is fixedly connected to one end of the spring away from the inner wall of the hollow tube. The other ends of the springs fixedly connected to the inner wall of the hollow tube are fixedly connected to the outer wall of the connecting rod. A counterweight is fixedly connected to the rear side of the outer wall of the connecting rod.

[0008] Preferably, the hollow tube is made of an elastic metal material, and the gravity on the connecting rod is greater than the force required for the hollow tube to deform.

[0009] Preferably, the sum of the height of the hollow tube and the height of the stop is greater than the distance between the inner wall of the fixed tube and the outer wall of the fixed rod.

[0010] Preferably, the height of the threaded plate is less than the height of the stop block.

[0011] This invention provides a dedicated mixing device for dry powder mortar production. It has the following beneficial effects:

[0012] 1. This special mixing device for dry mortar production is used to mix mortar inside the drum. After mixing, the drum is reversed to discharge the mortar. Water is then supplied through the water inlet pipe so that the water is evenly sprayed into the inside of the drum through the water outlet to achieve uniform cleaning.

[0013] 2. This special mixing device for dry mortar production rotates the sealing plate and fixed pipe simultaneously with the discharge, causing the vibration mechanism to impact the baffle, which in turn causes the baffle and mixing blades to vibrate. This dislodging causes some of the mortar adhering to the mixing blades to fall off, making it easier to clean later.

[0014] 3. This special mixing device for dry mortar production, after the vibration mechanism hits the stop block, the connecting rod will vibrate due to the counterweight of the connecting rod and the elasticity of the spring. This will cause the hollow tube to vibrate continuously when it contacts the stop block again, thus increasing the frequency and duration of the vibration and achieving a better cleaning effect.

[0015] 4. This special mixing device for dry mortar production, while rotating and spraying water inside the fixed pipe, causes the water to flow rapidly along the guide of the threaded plate, resulting in a certain angle and the inertia of the water flow when it is sprayed out of the water outlet. This prevents water from spraying onto the inner wall of the vertical roller, thus achieving a better cleaning effect. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0025] Please see Figure 1-6This invention provides a technical solution: a special mixing device for dry mortar production, comprising a support 1, a roller 6 fixedly connected to the upper side of the outer wall of the support 1, a motor 3 fixedly connected to the outer wall of the support 1, a friction wheel 8 fixedly connected to the output end of the motor 3, a transmission wheel 7 in contact with the outer wall of the friction wheel 8, the outer wall of the transmission wheel 7 in contact with the roller 6, a roller 2 fixedly connected to the inner wall of the transmission wheel 7, the front side of the roller 2 being open, a sealing plate 9 fixedly connected to the rear side of the roller 2, the sealing plate 9 sealing the rear side of the roller 2, a stirring blade 4 fixedly connected to the inner wall of the roller 2, the stirring blade 4 being spirally arranged inside the roller 2, and a cleaning mechanism 5 being provided in the middle of the stirring blade 4.

[0026] The cleaning mechanism 5 includes a fixed pipe 501, which is located in the middle of the drum 2. The outer wall of the fixed pipe 501 is rotatably connected to the outer wall of the stirring blade 4 through a bearing. The rear side of the fixed pipe 501 is fixedly connected to the front side of the sealing plate 9. The front end of the fixed pipe 501 is rotatably connected to a water inlet pipe 502 through a bearing. Several water outlet holes 503 are opened on the fixed pipe 501. The water outlet holes 503 are evenly distributed in a ring on the fixed pipe 501. A one-way valve is installed inside the water outlet hole 503. The input end of the one-way valve is located inside the fixed pipe 501. A knocking mechanism 504 is installed inside the fixed pipe 501.

[0027] The striking mechanism 504 includes a fixed rod 401, which is located inside the fixed tube 501. The rear end of the fixed rod 401 is connected to the front side of the sealing plate 9 via a ratchet structure. The ratchet structure at the connection between the fixed rod 401 and the sealing plate 9 can only support the fixed rod 401 to rotate clockwise. A vibration mechanism 402 is provided on the lower side of the outer wall of the fixed rod 401. A threaded plate 403 is fixedly connected to the inner wall of the water outlet 503. The height of the threaded plate 403 is less than the height of the stop block 404. The threaded plate 403 is arranged in a spiral pattern inside the water outlet 503. The stop block 404 is fixedly connected to the inner wall of the water outlet 503.

[0028] The vibration mechanism 402 includes a hollow tube 201 located inside the fixed tube 501. The upper outer wall of the hollow tube 201 is fixedly connected to the outer wall of the fixed rod 401. A spring 202 is fixedly connected to the inner wall of the hollow tube 201. Springs 202 are provided on all four inner walls of the hollow tube 201. A connecting rod 203 is fixedly connected to one end of the spring 202 away from the inner wall of the hollow tube 201. The other ends of the springs 202 fixedly connected to the inner wall of the hollow tube 201 are fixedly connected to the outer wall of the connecting rod 203. The hollow tube 201 is made of an elastic metal material. The weight of the connecting rod 203 is greater than the force required for the hollow tube 201 to deform. A counterweight 204 is fixedly connected to the rear side of the outer wall of the connecting rod 203. The sum of the height of the hollow tube 201 and the height of the stop 404 is greater than the distance between the inner wall of the fixed tube 501 and the outer wall of the fixed rod 401.

[0029] When in use, dry mortar is fed into the inside of the drum 2 through the front side of the drum 2. The motor 3 is connected to the mains power, so that the motor 3 drives the friction wheel 8 to rotate, which in turn drives the transmission wheel 7 to rotate the drum 2. The drum 2 drives the mixing blade 4 to rotate clockwise to mix the mortar inside the drum 2.

[0030] After the mortar is mixed in the drum 2, the motor 3 is started to reverse, so that the motor 3 drives the transmission wheel 7 to rotate in the opposite direction through the friction wheel 8, and the mortar inside the drum 2 is poured out by the counterclockwise rotation of the stirring blade 4.

[0031] As the drum 2 rotates counterclockwise, the sealing plate 9 also rotates counterclockwise. Because a ratchet structure is provided at the connection between the fixed rod 401 and the sealing plate 9, and this ratchet structure can only support the fixed rod 401 to rotate clockwise relative to the sealing plate 9, the fixed rod 401 rotates with the drum 2 during mortar mixing. When the drum 2 rotates counterclockwise, the counterweight of the vibration mechanism 402 keeps the fixed rod 401 relatively stationary, causing the drum 2 and the sealing plate 9 to rotate the fixed tube 501. Simultaneously, the rotation of the fixed tube 501 causes the stop block 404 to rotate. Since the sum of the height of the hollow tube 201 and the height of the stop block 404 is greater than the distance between the inner wall of the fixed tube 501 and the outer wall of the fixed rod 401, the stop block 404 will be blocked by the hollow tube 201 when it moves to the lower side of the hollow tube 201. Since the hollow tube 201 is made of an elastic metal, the weight of the connecting rod 203 is greater than the force required for the hollow tube 201 to deform. This causes the stop block 404 to squeeze the hollow tube 201, causing it to deform. After the hollow tube 201 deforms and accommodates the stop block 404, the elasticity of the hollow tube 201 and the squeezing of the stop block 404 cause the hollow tube 201 to drive the fixed rod 401 to quickly bounce and deflect clockwise, causing the hollow tube 201 to hit the next stop block 404, causing the stop block 404 to vibrate. The stop block 404 then transmits the vibration to the mixing blade 4 through the fixed tube 501, causing the mixing blade 4 to vibrate. This achieves the purpose of causing the mixing blade 4 to vibrate and shake off some of the mortar on its surface while discharging, facilitating subsequent cleaning work.

[0032] As the vibration mechanism 402 moves rapidly to the next stop 404, the hollow tube 201 quickly rebounds and returns to its shape after disengaging from the stop 404, and its movement speed is relatively fast. This causes the connecting rod 203 to vibrate rapidly inside the hollow tube 201 due to the elastic force of the spring 202. This causes the connecting rod 203 to drive the hollow tube 201 to produce continuous vibration, resulting in more intense vibration after contacting the next stop 404. The continuous vibration occurs before the stop 404 passes the hollow tube 201, maximizing the removal of mortar from the mixing blade 4 and facilitating subsequent cleaning.

[0033] After the material is discharged, the water is connected to the water pipe at the front end of the water inlet pipe 502, allowing water to flow into the interior of the fixed pipe 501 through the water inlet pipe 502. Then, it is quickly sprayed out through the water outlet 503, so that it can evenly rinse the interior of the roller 2. At the same time, the motor 3 is started to drive the roller 2 to rotate clockwise, so that the water sprayed into the interior of the roller 2 can better rinse the mortar inside the roller 2. Since the water outlet 503 evenly sprays mortar into all corners of the inner wall of the roller 2, the dead corners on the inner wall of the roller 2 are easier to clean. In addition, the threaded plate 403 forms a guiding effect inside the fixed pipe 501. When the fixed pipe 501 rotates and sprays water, the water flows quickly along the guide of the threaded plate 403, so that when it sprays out of the water outlet 503, it generates a certain angle and the inertia of the water flow itself, which can prevent the water from spraying perpendicularly to the inner wall of the roller 2, thus achieving a better cleaning effect. After cleaning the interior of the roller 2, the motor 3 is started to drive the roller 2 to rotate counterclockwise to discharge the wastewater.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
