Description

Technical Field

[0001] The present invention relates to the technical field of processing of lightweight building material blocks, and particularly to a mortar coating device for civil engineering lightweight materials. Background Art

[0002] Lightweight materials are a new type of inorganic composite material made of alkali-resistant glass fiber as the reinforcing material, low-alkalinity sulphoaluminate cement as the binder, and appropriate aggregates added to form the base material, which are made by processes such as spraying, vertical casting, extrusion, and slurry flow, etc., to replace stones, sand, etc., and can greatly reduce the weight.

[0003] Lightweight material blocks are precast components made of lightweight materials. During the processing and manufacturing of lightweight material blocks, in order to enhance their protection, durability, functionality, etc., cement mortar is usually coated on their exterior. This not only provides physical protection to prevent the material blocks from being mechanically damaged and water permeating; but also can improve the fire resistance and structural strength, enhance the overall stability; can also improve the appearance, making the surface smoother and more beautiful; can further enhance the heat insulation performance, and is convenient for construction, ensuring that the lightweight material blocks play the best performance in buildings.

[0004] After retrieval, a Chinese invention patent with the publication number of CN103231448B discloses an automatic cement mortar coating device for lightweight material blocks, including a base, a conveying device is installed on the base, the conveying device is connected to a power device, the base is connected to a supporting device, several pressing rollers are fixed on the supporting device, and there is a distance H for installing lightweight material blocks between the pressing rollers and the upper surface of the conveying device. A cement mortar hopper is installed on the base and on the right side of the conveying device. A product inlet is opened on the first side plate corresponding to the walking direction of the conveying device for conveying lightweight material blocks on the cement mortar hopper, and a product outlet is opened on the second side plate corresponding to the product inlet. This application uses a scraper to coat mortar on the surface of the lightweight material block during its walking. However, since the conveying device will also block the bottom surface of the material block while driving it to move, it is difficult for this device to fully and effectively coat the mortar. Although six-sided coating can be achieved through secondary operation, it will reduce the efficiency of coating mortar on the material block, resulting in inconvenience in this processing process. Summary of the Invention

[0005] Aiming at the above-mentioned prior art, the present invention provides a mortar coating device for civil engineering lightweight materials, and the main technical problem to be solved lies in how to ensure the efficiency of coating mortar on lightweight material blocks.

[0006] To achieve the above object, the technical solution of the embodiment of the present invention is realized as follows:

[0007] A mortar coating device for civil engineering lightweight materials, including a mortar pool for containing mortar. A circulating mechanism for spraying mortar and a cage for containing lightweight material blocks are provided in the mortar pool. The circulating mechanism performs coating by spraying mortar onto the cage.

[0008] The circulating mechanism includes a material cylinder with a spiral blade inside. Several guiding plates are provided at one top side of the material cylinder. A driving mechanism and a rotating mechanism are also provided in the mortar pool. The rotating mechanism includes a rotating cylinder and a rotating rod. The driving mechanism is used to drive the spiral blade and the rotating cylinder to rotate continuously and drive the rotating rod to rotate intermittently. The spiral blade transports mortar to the guiding plates for spraying by rotation. The rotating cylinder drives the cage to rotate continuously to turn over the lightweight material blocks, and the rotating rod drives the cage to rotate intermittently around the public axis to rotate and replace the lightweight material blocks.

[0009] Furthermore, a partition board is fixedly connected to the inner bottom end of the mortar pool. A circular opening is provided in the middle of the partition board. The rotating cylinder is rotatably connected to the partition board at the circular opening. A circular through-hole is provided at the top of the rotating cylinder. The rotating rod is rotatably connected to the rotating cylinder at the circular through-hole. A turntable is fixedly connected to the top of the rotating rod. Several connecting rods are rotatably connected at equal intervals on the outside of the turntable.

[0010] Furthermore, one end of the connecting rod is fixedly connected with a baffle. Several support rods are fixedly connected at equal intervals on the outside of one side of the baffle. The cage is located between several support rods. A gasket is fixedly connected to the side wall of the baffle on the inner side of the cage. Several convex blocks are provided at equal intervals on the inner wall of the cage. The materials of the convex blocks and the gaskets are both rubber.

[0011] Furthermore, a driven wheel is connected to the outside of the rod body of the connecting rod by a key. A driving wheel is connected to the outside of the top end of the rotating cylinder by a key. Both the driving wheel and the driven wheel are bevel gears. The driving wheel meshes with the driven wheel. A second gear is connected to the outside of the rotating cylinder below the partition board by a key. A first gear is connected to the outside of the rod body of the rotating rod below the partition board by a key.

[0012] Furthermore, a machine shell is fixedly connected to the top of the partition board on one side of the rotating cylinder. Several vibrating rods are fixedly connected at equal intervals on the outside of the machine shell. The driving mechanism includes a motor fixed in the machine shell. A first through-hole is provided in the partition board on the inner side of the machine shell. A connecting shaft is rotatably connected to the partition board at the first through-hole. The bottom end of the output shaft of the motor is fixedly connected to the connecting shaft.

[0013] Furthermore, a third gear and a fourth gear are connected to the outside of the rod body of the connecting shaft below the partition board by a key. The diameters of the third gear and the fourth gear are equal. The third gear is an incomplete gear. The third gear meshes with the first gear. The fourth gear meshes with the second gear. The diameter of the fourth gear is smaller than that of the second gear. The diameters of the second gear and the first gear are equal.

[0014] Further, the barrel is fixedly connected to one side of the top end of the partition plate. A second through hole is formed in the plate body of the partition plate inside the barrel. A rotating shaft is rotatably connected to the partition plate at the second through hole. The spiral blade is fixedly connected to the outer part of the rod body of the rotating shaft in the barrel. Belt pulleys are connected to the outer parts of the rod bodies of the rotating shaft and the connecting shaft below the partition plate by keys, and the same belt is sleeved outside the two belt pulleys.

[0015] Further, a plurality of feed ports are equidistantly arranged at the outer bottom end of the barrel, and a plurality of discharge ports are equidistantly arranged at one side of the top end of the barrel close to the rotating cylinder. The number of the feed ports is greater than that of the discharge ports. The number of the guide plates is the same as that of the discharge ports and they correspond one by one. The guide plates are fixedly connected to the barrel at the discharge ports. The lengths of the plurality of guide plates gradually shorten from top to bottom. The guide plates are arc-shaped, and material grooves are formed in the guide plates.

[0016] Further, a bearing is arranged on the outer part of the cage on the side far from the baffle, and a handle is fixedly connected to the side of the bearing far from the baffle.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. This device uses a cage to hold lightweight material blocks, and cooperates with the rotation of the spiral blade to make the mortar circulate, so that the mortar can be sprayed onto the surface of the material blocks to achieve the effect of coating the mortar. At the same time, this device can drive the cage to rotate continuously and revolve intermittently. The former can make the material blocks tumble to ensure the fullness and uniformity of the mortar coating, and the latter can realize the rotation and replacement of different material blocks, and can use the operation gap to take and place the material blocks to ensure the coherence and convenience of the mortar coating process. Therefore, this device can fully, evenly and conveniently coat the mortar on the material blocks, so as to ensure the efficiency of the processing process.

[0019] 2. Since the operation of the motor will inevitably generate vibration and cause the vibration of the machine shell, and the machine shell is immersed in the mortar, the shock rod arranged outside the machine shell can conduct the vibration to the mortar to cause the mortar to oscillate to maintain its uniformity, and avoid precipitation and stratification, which may lead to uneven coating.

[0020] 3. By setting a handle on the cage, the handle can be used to conveniently push and pull the cage to facilitate its taking and placing between several support rods. In addition, since the process of the fourth gear driving the second gear can achieve a deceleration effect, and when holding the handle, the bearing can offset the driving effect of the cage on the handle, it can avoid the continuous rotation of the cage from interfering with the taking out of the material blocks.

Detailed implementation manners

[0028] The technical solution of the present invention will be further elaborated in detail below in conjunction with the drawings in the specification and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] Embodiment 1

[0030] Referring to the attached Figures 1-4 , the present application provides a mortar coating device for a civil engineering lightweight material, including a mortar pool 1 for containing mortar. A circulation mechanism for spraying mortar and a cage 25 for containing lightweight material blocks are provided in the mortar pool 1. The circulation mechanism performs coating by spraying mortar onto the cage 25; One end of the connecting rod 22 is fixedly connected with a baffle 23, and a plurality of support rods 24 are fixedly connected at equal intervals on the outside of one side of the baffle 23, and the cage 25 is located between the plurality of support rods 24.

[0031] When it is necessary to coat the lightweight material blocks with mortar, the material blocks can be placed therein after removing the wire cage 25, and then the wire cage 25 is pushed back between several struts 24. At this time, the struts 24 can clamp the wire cage to limit the position of the material blocks. Then, after injecting cement mortar into the slurry coating pool 1, the motor 17 can be started.

[0032] The circulation mechanism includes a material cylinder 14. A spiral blade 12 is arranged inside the material cylinder 14. Several guide plates 15 are arranged at one side top end of the material cylinder 14. A driving mechanism and a rotating mechanism are also arranged in the slurry coating pool 1. The rotating mechanism includes a rotating cylinder 3 and a rotating rod 4. The driving mechanism is used to drive the spiral blade 12 and the rotating cylinder 3 to rotate continuously and drive the rotating rod 4 to rotate intermittently. The spiral blade 12 conveys the mortar to the guide plates 15 for spraying through rotation. The rotating cylinder 3 drives the wire cage 25 to rotate continuously to turn over the lightweight material blocks, and the rotating rod 4 drives the wire cage 25 to rotate intermittently in a revolution to rotate and replace the lightweight material blocks.

[0033] Preferably, the material cylinder 14 is fixedly connected to one side top end of the partition plate 2. A second through hole is formed in the plate body of the partition plate 2 inside the material cylinder 14. A rotating shaft 13 is rotatably connected to the partition plate 2 at the second through hole. The spiral blade 12 is fixedly connected to the outer part of the rod body of the rotating shaft 13 in the material cylinder 14. Pulley 11 is key-connected to the outer parts of the rod bodies of the rotating shaft 13 and the connecting shaft 7 below the partition plate 2. The same belt 10 is sleeved outside the two pulleys 11.

[0034] Preferably, a plurality of feed ports are equidistantly arranged at the outer bottom end of the material cylinder 14, and a plurality of discharge ports are equidistantly arranged at one side top end of the material cylinder 14 close to the rotating cylinder 3. The number of the feed ports is greater than that of the discharge ports. By making the feed amount greater than the discharge amount, it can ensure that materials can flow out at several discharge ports with different heights. The number of the guide plates 15 is the same as that of the discharge ports and they are in one-to-one correspondence. The guide plates 15 are fixedly connected to the material cylinder 14 at the discharge ports. The lengths of the several guide plates 15 gradually shorten from top to bottom. The guide plates 15 are arc-shaped, and material grooves are formed in the guide plates 15. Through the guide plates 15 with gradually shortening lengths from top to bottom, the area of spraying the mortar can be enlarged, that is, multiple spraying points can be created in the axial direction of the wire cage 25 to ensure the sufficiency of spraying the mortar, and further ensure the sufficient coating of the mortar on the material blocks.

[0035] The motor 17 can drive the connecting shaft 7 to rotate. On the one hand, the connecting shaft 7 can drive the rotating shaft 13 through the belt 10 and the two pulleys 11. The rotating shaft 13 drives the spiral blade 12 to rotate, and then the mortar in the slurry coating pool 1 can be pumped into the material cylinder 14 and conveyed from bottom to top to the guide plates 15 and discharged along the material grooves on the guide plates 15, so as to make the mortar circulate and form a liquid flow at the guide plates 15.

[0036] Preferably, a partition plate 2 is fixedly connected to the inner bottom end of the patina pool 1. A circular opening is formed in the middle of the plate body of the partition plate 2. The rotating cylinder 3 is rotatably connected to the partition plate 2 at the circular opening. A circular through hole is formed at the top end of the rotating cylinder 3. The rotating rod 4 is rotatably connected to the rotating cylinder 3 at the circular through hole. The top end of the rotating rod 4 is fixedly connected to a turntable 19. A plurality of connecting rods 22 are rotatably connected to the outside of the turntable 19 at equal intervals. A gasket 2301 is fixedly connected to the side wall of the baffle 23 inside the wire cage 25. A plurality of bumps 2501 are arranged on the inner wall of the wire cage 25 at equal intervals. The materials of the bumps 2501 and the gasket 2301 are both rubber.

[0037] While the connecting shaft 7 drives the rotating shaft 13 to rotate, the connecting shaft 7 can also drive the third gear 8 and the fourth gear 9 to rotate. The fourth gear 9 drives the rotating cylinder 3 to rotate through the second gear 6. The rotating cylinder 3 drives the driven wheel 21 to rotate through the driving wheel 20. The driven wheel 21 drives the baffle 23 to rotate through the connecting rod 22. The baffle 23 can make the material block flip by driving the wire cage 25 to rotate self - sufficiently; during this process, since the wire cage 25 is covered with bumps 2501 and the baffle 23 is provided with gaskets 2301, the safety of the material block during flipping can be ensured.

[0038] Preferably, a driven wheel 21 is connected to the outside of the rod body of the connecting rod 22 by a key. A driving wheel 20 is connected to the outer top end of the rotating cylinder 3 by a key. Both the driving wheel 20 and the driven wheel 21 are bevel gears. The driving wheel 20 meshes with the driven wheel 21. A second gear 6 is connected to the outside of the rotating cylinder 3 below the partition plate 2 by a key. A first gear 5 is connected to the outside of the rod body of the rotating rod 4 below the partition plate 2 by a key.

[0039] In addition, the third gear 8 drives the rotating rod 4 to rotate through the first gear 5. The rotating rod 4 drives the connecting rod 22 to rotate through the turntable 19. The connecting rod 22 can make the wire cage 25 revolve around the rotating rod 4 as the axis through the baffle 23. Therefore, different wire cages 25 can be rotated in turn to move to the guide plate 15. Thus, the mortar left on the guide plate 15 can be poured onto the wire cage 25 and coated on the outside of the material block. By cooperating with the flipping of the material block caused by the self - rotation of the wire cage 25, the uniformity and sufficiency of the mortar coating can be ensured.

[0040] Preferably, a third gear 8 and a fourth gear 9 are connected to the outside of the rod body of the connecting shaft 7 below the partition plate 2 by a key. The diameter of the third gear 8 is equal to the diameter of the fourth gear 9. The third gear 8 is an incomplete gear. The third gear 8 meshes with the first gear 5. The fourth gear 9 meshes with the second gear 6. The diameter of the fourth gear 9 is smaller than the diameter of the second gear 6. The diameter of the second gear 6 is equal to the diameter of the first gear 5.

[0041] In addition, since the third gear 8 is an incomplete gear, the process of driving the cage 25 to revolve will be intermittent. By utilizing this intermittence, not only can the rotation of the cage 25 be coordinated to allow the material blocks to be fully coated with mortar, but also the material blocks can be taken and placed by loading and unloading the cage 25 during the intermittence, so as to continuously carry out the work of coating the material blocks with mortar. Since the diameter of the third gear 8 is smaller than that of the first gear 5, and the diameter of the fourth gear 9 is smaller than that of the second gear 6, both of these driving processes can achieve the effect of deceleration, thereby ensuring that both the rotation and revolution of the cage 25 can be relatively slow to avoid the centrifugal force from affecting the mortar coating process.

[0042] In the above process, since the diameters of the third gear 8 and the fourth gear 9 are equal, and the diameters of the first gear 5 and the second gear 6 are equal, when the third gear 8 rotates to mesh with the first gear 5, the rotating drum 3 and the rotating rod 4 will rotate synchronously. At this time, the relative motion between the driving wheel 20 and the driven wheel 21 is stationary, so the cage 25 will not rotate. Moreover, since the rotation of the small-diameter third gear 8 driving the large-diameter fourth gear 9 has a decelerating effect, the cage 25 can be pulled and pushed during the above process to take and place the material blocks. When the third gear 8 rotates to be disengaged from the first gear 5, the rotating rod 4 cannot rotate due to the existence of the damping force, so the rotation of the rotating drum 3 can drive the driven wheel 21 by the driving wheel 20, thereby realizing the continuous rotation of the cage 25.

[0043] Preferably, at the top end of the partition plate 2 on one side of the rotating drum 3, a machine shell 16 is fixedly connected. A plurality of vibrating rods 18 are fixedly connected to the outside of the machine shell 16 at equal intervals. The driving mechanism includes a motor 17, and the motor 17 is fixedly connected in the machine shell 16. A first through hole is opened in the plate body of the partition plate 2 inside the machine shell 16. A connecting shaft 7 is rotatably connected to the partition plate 2 at the first through hole. The bottom end of the output shaft of the motor 17 is fixedly connected to the connecting shaft 7.

[0044] During the operation of the motor 17, since its operation will inevitably generate vibrations and cause the machine shell 16 to vibrate, the vibrations can be transmitted to the mortar by using the vibrating rods 18 arranged on the outer surface of the machine shell 16, so as to cause the mortar to oscillate to avoid precipitation and stratification, and further ensure the uniform effect of mortar coating.

[0045] Embodiment 2

[0046] Referring to the attached Figure 5 , the present application provides a mortar coating device for civil engineering lightweight materials. Compared with Embodiment 1, in order to facilitate the taking and placing of the material blocks, a bearing 26 is provided on the outside of the cage 25 on the side far from the baffle 23. A handle 27 is fixedly connected to the side of the bearing 26 far from the baffle 23. The bearing 26 includes an inner ring, an outer ring, and a plurality of steel balls arranged between the inner and outer rings. The handle 27 is fixedly connected to the outer ring, and the inner ring is fixedly connected to the cage 25, so as to ensure that relative rotation can occur between the handle 27 and the cage 25.

[0047] The cage 25 can be conveniently pushed and pulled by holding the handle 27 to load and unload the material blocks, and the presence of the bearing 26 can offset the driving effect of the cage 25 on the handle 27. Therefore, even when the cage 25 is rotating, the cage 25 can be loaded and unloaded through the handle 27, so as to further ensure the convenience of loading and unloading the material blocks.

[0048] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the said claims.
