Description

Technical Field

[0001] This invention belongs to the field of building construction technology and relates to an epoxy polymer modified cement mortar coating equipment and coating method. Background Technology

[0002] The product characteristics of modified epoxy polymer mortar are: it has the properties of impermeability, freeze resistance, salt resistance, alkali resistance, and weak acid corrosion resistance, and has strong adhesion to a variety of materials; it can be applied to damp substrates without drying, and can harden in humid environments or underwater; it is easy to apply and apply, similar to ordinary cement mortar, and is easy to clean, requiring only water.

[0003] Its construction process is as follows:

[0004] 1. Base surface treatment: Use an angle grinder to grind the concrete surface smooth and remove the thin cement paste layer, dirt and other attachments on the base surface to expose the concrete.

[0005] 2. Surface cleaning: Use high-pressure water or high-pressure air to remove sand and dust from the surface;

[0006] 3. Spot scraping and base layering: Use a triangular shovel or small scraper to fill the air holes, rough surfaces and grooves on the base working surface with epoxy putty to make them dense;

[0007] 4. Surface leveling: When the first layer of epoxy mortar has largely cured (about 4-12 hours after construction), use a scraper to scrape the second layer of epoxy mortar in a large arc back and forth motion. The surface of the finished construction layer should be flat, smooth, and free of construction seams and scratches.

[0008] A search revealed that utility model CN218541380U discloses a wall cement mortar plastering machine, including a lifting assembly. The lifting assembly includes a U-shaped groove with a sloping groove fixedly connected to its bottom. Two second fixed square tubes are fixedly connected to both sides of the sloping groove. A lifting square tube is located inside the second fixed square tube. A third fixed square tube is fixedly connected to the bottom of the front side of the lifting square tube, and a fifth fixed square tube is fixedly connected to the bottom of the back side of the lifting square tube. Fourth fixed square tubes are fixedly connected to the bottom of both sides of the two third fixed square tubes. A first fixed square tube is movably engaged at the top of the lifting square tube. Pulley assemblies are fixedly connected to both sides of the top of the first fixed square tube. This facilitates effective plastering of the wall and allows for further smoothing of the cement adhering to the wall after plastering, reducing the time required for workers to smooth the cement after it has adhered to the wall.

[0009] The device also has the following disadvantages when in use: When using it, cement is applied to the wall surface through a cement trowel, but since the trowel is flat, the fallen cement is easy to collect, and the wall surface needs to be manually sanded beforehand, which is inefficient. Moreover, once a wall surface is smoothed, it is not convenient to move it, making it difficult for one person to use. Therefore, we propose an epoxy polymer modified cement mortar coating equipment and coating method to solve the above-mentioned problems. Summary of the Invention

[0010] In view of this, in order to solve the problems that the trowel is a flat surface, the fallen cement is easy to collect, and the previous step requires manual grinding of the wall surface, which is inefficient, and the wall surface is inconvenient to move after being troweled, making it difficult for one person to use, the present invention provides an epoxy polymer modified cement mortar coating equipment and coating method.

[0011] To achieve the above objectives, the present invention provides the following technical solution: an epoxy polymer modified cement mortar coating equipment, comprising a base and a sludge pump assembly, wherein two support frames are fixedly connected to the top of the base, and sliding blocks are slidably sleeved on the outer wall of the support frames, and a slurry frame for holding cement is fixedly connected between the two sliding blocks, and a first scraper is fixedly connected to the top of the slurry frame for applying cement to the wall surface, and the sludge pump assembly is disposed on one side of the slurry frame for pumping cement into the slurry frame;

[0012] The top of the mud frame is fixedly connected to a collection frame for collecting abrasive particles. Inside the collection frame is a rotating disc for grinding the wall surface. A connecting cylinder is fixedly connected through the side of the collection frame away from the rotating disc. A cloth bag for holding particles is fitted on the outer wall of the connecting cylinder.

[0013] The collection mechanism, located inside the collection frame, is used to move the particles that fall off during grinding.

[0014] The transmission mechanism, located inside the mud frame, is used to move the mud frame and move the cement onto the first scraper.

[0015] Furthermore, the collection mechanism includes two sets of pulleys rotatably connected to the inner wall of the collection frame. The outer wall of each set of pulleys is connected to the same connecting belt. Multiple third scrapers are fixedly connected to the outer walls of the two connecting belts. A brush for cleaning particles is fixedly connected to the bottom of each third scraper.

[0016] Furthermore, the transmission mechanism includes a rack that slides through the inner wall of the sliding block, the rack being fixedly connected to one side of the support frame, a second rotating rod being rotatably connected between the two sliding blocks and through the inner wall of the mud frame, a first motor being fixedly connected to one side of one of the sliding blocks, the output end of the first motor being fixedly connected to the second rotating rod, and a gear meshing with the rack being fixedly sleeved on the outer wall of the second rotating rod.

[0017] Furthermore, a connecting plate is fixedly connected to the inner wall of the collection frame, and both rotating disks are rotatably connected to one side of the connecting plate. The outer walls of the rotating disks are fixedly fitted with meshing external toothed rings. A W-shaped ash-pouring plate corresponding to the two rotating disks is fixedly connected to the bottom inner wall of the collection frame. Multiple scrapers are fixedly connected to one side of the rotating disks, and one side of the W-shaped ash-pouring plate is flush with the scrapers.

[0018] Furthermore, a first rotating rod is rotatably connected through one side of the collection frame, and a conveying roller is fixedly sleeved on the outer wall of the first rotating rod. The third scraper is located inside the conveying roller. Synchronous pulleys are fixedly sleeved on the outer walls of the rotating shafts of the first rotating rod and the corresponding rotating disk. The outer walls of the two synchronous pulleys are connected to the same synchronous belt. A second motor is fixedly connected to one side of the collection frame, and the output end of the second motor is fixedly connected to one end of the first rotating rod.

[0019] Furthermore, two L-shaped blocks are rotatably connected to both sides of the base. Rollers are fixedly connected to the bottom of the L-shaped blocks. A waist-shaped hole is opened on the inner wall of the L-shaped block. A nut block is provided on the inner wall of the waist-shaped hole. Two fixing blocks are fixedly connected to both sides of the base. A screw rod is rotatably connected through the two fixing blocks on the same side. The two nut blocks on the same side are threaded onto the screw rod.

[0020] Furthermore, a second scraper is rotatably connected to the inner wall of the mud frame. An arc-shaped plate is fixedly connected to the side of the second scraper near the mud frame. A middle baffle is fixedly connected to the bottom of the second scraper. The middle baffle contacts the top of the first scraper. Side baffles are fixedly connected to both ends of the first scraper.

[0021] Furthermore, a lifting plate is slidably connected to the inner wall of the mud frame, and rotating wheels are rotatably connected to the bottom inner wall of the collection frame. Two connecting ropes are fixedly connected to the top of the lifting plate, and the other end of the connecting ropes is fixedly connected to the arc plate after passing around the rotating wheels. Grooves corresponding to the connecting ropes are opened on both sides of the arc plate. Tension springs are fixedly connected to the side baffles on both sides of the other end of the second scraper. Two abutting blocks that cooperate with the arc plate are fixedly sleeved on the outer wall of the second rotating rod.

[0022] Furthermore, a rectangular groove is provided on the side of the second scraper away from the arc plate, and a telescopic plate is slidably provided on the inner wall of the rectangular groove. Multiple springs are fixedly connected between the telescopic plate and the rectangular groove, and the telescopic plate is in contact with the wall surface.

[0023] A method for applying epoxy polymer-modified cement mortar includes the following steps:

[0024] S1. Push the device to one side of the wall so that both the first scraper and the second scraper are in contact with the wall. Rotate the screw. The screw can drive the two nut blocks to move closer to each other. Through the setting of the waist-shaped hole, the two L-shaped blocks can be driven to rotate relative to each other so that one side of the L-shaped block contacts the ground. The device can be fixed to one side of the wall.

[0025] S2. Start the second motor. The second motor can drive the first rotating rod to rotate. The first rotating rod drives one of the rotating disks to rotate through the synchronous pulley and synchronous belt. The rotating disk drives the scraper to rotate, which can grind the wall. The rotating disk can drive another rotating disk to rotate in the opposite direction through the external toothed ring, and grind the wall surface at the same time. The particles ground off fall into the collection frame through the W-shaped dust collection plate. The rotation of the first rotating rod drives the conveyor roller to rotate. The rotation of the conveyor roller can drive the third scraper to move. Thus, multiple third scrapers are driven to move simultaneously through the pulley and connecting belt. The movement of the third scrapers can push the particles into the collection frame for collection.

[0026] S3. Start the sludge pump assembly to pump the prepared cement to the lifting plate inside the sludge frame. Start the first motor, which can drive the second rotating rod to rotate. The second rotating rod can drive the sludge frame and collection frame to move upward through the rack and gear. The second rotating rod can drive the contact block to rotate. When the contact block contacts the rectangular groove, it can drive the arc plate to move. The movement of the arc plate can drive the second scraper to rotate inside the sludge frame. The rotation of the second scraper can drive the middle baffle to rotate. At the same time, the movement of the arc plate can drive the lifting plate to rise through the connecting rope and rotating wheel, which can drive the cement to rise. The cement can flow into the arc plate and onto the first scraper.

[0027] S4. When the contact block moves away from the curved plate, the second scraper automatically resets under the force of the tension spring, causing the middle baffle to rotate and contact the first scraper, closing one side of the first scraper. This allows the second scraper to rotate back and forth, allowing the cement in the curved plate to flow onto the second scraper. The rotation of the second scraper can cause the telescopic plate to contact the wall, allowing cement to be applied to the concave wall surface. As it continues to move upward, the cement on the first scraper flows onto the wall surface, and the upward movement of the first scraper smooths it out.

[0028] The beneficial effects of this invention are as follows:

[0029] 1. The epoxy polymer modified cement mortar coating equipment disclosed in this invention pushes the device to one side of the wall so that the first scraper and the second scraper are in contact with the wall. By rotating the screw, the screw can drive the two nut blocks to move closer to each other. Through the setting of the waist-shaped hole, the two L-shaped blocks can be driven to rotate relative to each other so that one side of the L-shaped block contacts the ground, and the device can be fixed to one side of the wall.

[0030] 2. The epoxy polymer modified cement mortar coating equipment disclosed in this invention, by starting a second motor, can drive a first rotating rod to rotate. The first rotating rod drives one of the rotating disks to rotate via a synchronous pulley and a synchronous belt. The rotating disk drives the scraper to rotate, which can grind the wall. The rotating disk drives another rotating disk to rotate in the opposite direction via an external toothed ring, which can grind the wall surface at the same time. The particles ground off fall into the collection frame through a W-shaped ash-pouring plate. The rotation of the first rotating rod drives the conveyor roller to rotate. The rotation of the conveyor roller can drive the third scraper to move. Thus, multiple third scrapers move simultaneously via a pulley and a connecting belt. The movement of the third scrapers can push the particles into the collection frame for collection.

[0031] 3. The epoxy polymer modified cement mortar coating equipment disclosed in this invention, by starting the sludge pump assembly, pumps the prepared cement to the lifting plate in the sludge frame. The first motor is started, which can drive the second rotating rod to rotate. The second rotating rod can drive the sludge frame and the collection frame to move upward through the rack and gear. The second rotating rod can drive the contact block to rotate. When the contact block contacts the rectangular groove, it can drive the arc plate to move. The movement of the arc plate can drive the second scraper to rotate in the sludge frame. The rotation of the second scraper can drive the middle baffle to rotate. At the same time, the movement of the arc plate can drive the lifting plate to rise through the connecting rope and the rotating wheel, which can drive the cement to rise. The cement can flow into the arc plate and the first scraper.

[0032] 4. The epoxy polymer modified cement mortar coating equipment disclosed in this invention automatically resets the second scraper under the force of the tension spring, causing the middle baffle to rotate and contact the first scraper, closing one side of the first scraper. This allows the second scraper to rotate back and forth, allowing the cement in the arc plate to flow onto the second scraper. The rotation of the second scraper can cause the telescopic plate to contact the wall, allowing cement to be applied to the concave wall surface. As it continues to move upward, the cement on the first scraper flows onto the wall surface, and the upward movement of the first scraper smooths the surface.

[0033] This invention, by starting the second motor, can not only drive the third scraper to rotate and grind the wall, but also collect the ground particles into a collection frame for easy processing. Furthermore, starting the first motor can drive the mud frame to rise and fall, and can also drive the arc-shaped plate to dig up cement, moving the cement to the second scraper. At the same time, it can also drive the cement to rise and move the cement to the first scraper, making it easier to control the amount of cement taken and making it convenient to use.

[0049] like Figure 1 As shown, an epoxy polymer modified cement mortar coating equipment includes a base 1 and a sludge pump assembly 32. Two support frames 2 are fixedly connected to the top of the base 1. Sliding blocks 8 are slidably sleeved on the outer wall of the support frames 2. A sludge frame 3 for holding cement is fixedly connected between the two sliding blocks 8. A first scraper 4 is fixedly connected to the top of the sludge frame 3 for applying cement to the wall surface.

[0051] A collection mechanism, located inside the collection frame 6, is used to move the particles that fall off during grinding;

[0052] The transmission mechanism, located inside the mud frame 3, is used to move the mud frame 3 and move the cement onto the first scraper 4. In the above technical solution, the wall surface can be polished by starting the rotating disk 7, and the particles that fall off the polishing can be moved into the collection frame 6 for collection by the collection mechanism. At the same time, starting the transmission mechanism can drive the mud frame 3 to rise, so that cement is applied to the wall surface while it rises, which saves manual application time and is easy to use. The sludge pump assembly 32 is the same as that used in patent document CN218541380U.

[0053] Example 2

[0054] Reference Figure 1 The present invention provides a new technical solution, an epoxy polymer modified cement mortar coating equipment, including a base 1 and a sludge pump assembly 32. Two support frames 2 are fixedly connected to the top of the base 1. Sliding blocks 8 are slidably sleeved on the outer wall of the support frames 2. A sludge frame 3 for holding cement is fixedly connected between the two sliding blocks 8. A first scraper 4 is fixedly connected to the top of the sludge frame 3 for applying cement to the wall surface. The sludge pump assembly 32 is set on one side of the sludge frame 3 for pumping cement into the sludge frame 3.

[0055] The top of the mud frame 3 is fixedly connected to a collection frame 6 for collecting abrasive particles. Inside the collection frame 6 is a rotating disc 7 for grinding the wall surface. A connecting cylinder 18 is fixedly connected through the side of the collection frame 6 away from the rotating disc 7. A cloth bag for holding particles is fitted on the outer wall of the connecting cylinder 18.

[0056] A collection mechanism, located inside the collection frame 6, is used to move the particles that fall off during grinding;

[0057] The transmission mechanism, located inside the mud frame 3, is used to move the mud frame 3 and move the cement onto the first scraper 4. In the above technical solution, the wall surface can be polished by starting the rotating disk 7, and the particles that fall off the polishing can be moved into the collection frame 6 for collection by the collection mechanism. At the same time, starting the transmission mechanism can drive the mud frame 3 to rise, so that cement is applied to the wall surface while it rises, which saves manual application time and is easy to use. The sludge pump assembly 32 is the same as that used in patent document CN218541380U.

[0058] Reference Figure 2 and Figure 3 The collection mechanism includes two sets of pulleys 15 rotatably connected to the inner wall of the collection frame 6. The outer wall of each set of pulleys 15 is connected to the same connecting belt 16. Multiple third scrapers 17 are fixedly connected to the outer walls of the two connecting belts 16. A brush for cleaning particles is fixedly connected to the bottom of the third scraper 17. In the above technical solution, by rotating one of the pulleys 15, the third scraper 17 can be moved through the connecting belt 16 to collect the falling particles.

[0059] Reference Figure 1 and Figure 4 The transmission mechanism includes a rack 24 that slides through the inner wall of the sliding block 8. The rack 24 is fixedly connected to one side of the support frame 2. A second rotating rod 26 is rotatably connected between the two sliding blocks 8 and the inner wall of the mud frame 3. A first motor 9 is fixedly connected to one side of one of the sliding blocks 8. The output end of the first motor 9 is fixedly connected to the second rotating rod 26. A gear 25 that meshes with the rack 24 is fixedly sleeved on the outer wall of the second rotating rod 26. In the above technical solution, starting the first motor 9 can drive the second rotating rod 26 to rotate. The second rotating rod 26 drives the gear 25 to rotate, thereby driving the mud frame 3 to move up and down through the rack 24.

[0060] Reference Figure 2 and Figure 3 A connecting plate 11 is fixedly connected to the inner wall of the collection frame 6. Two rotating disks 7 are rotatably connected to one side of the connecting plate 11. The outer wall of each rotating disk 7 is fixedly fitted with an engaging external toothed ring 13. A W-shaped dust-pouring plate 12 corresponding to the two rotating disks 7 is fixedly connected to the bottom inner wall of the collection frame 6. Multiple scrapers 14 are fixedly connected to one side of the rotating disk 7. One side of the W-shaped dust-pouring plate 12 is flush with the scraper 14. In the above technical solution, rotating one of the rotating disks 7 can drive the other rotating disk 7 to rotate together, increasing its grinding area. The particles that fall off during grinding fall into the collection frame 6 through the W-shaped dust-pouring plate 12, making it easy to collect.

[0061] Reference Figure 3A first rotating rod 19 is rotatably connected through one side of the collection frame 6. A conveying roller 20 is fixedly sleeved on the outer wall of the first rotating rod 19. A third scraper 17 is located inside the conveying roller 20. Synchronous wheels 21 are fixedly sleeved on the outer walls of the rotating shafts of the first rotating rod 19 and the corresponding rotating disk 7. The outer walls of the two synchronous wheels 21 are connected to the same synchronous belt 22. A second motor 23 is fixedly connected to one side of the collection frame 6. The output end of the second motor 23 is fixedly connected to one end of the first rotating rod 19. In the above technical solution, starting the second motor 23 can drive the first rotating rod 19 to rotate. The rotation of the first rotating rod 19 can drive the conveying roller 20 to rotate. The rotation of the conveying roller 20 can drive the third scraper 17 to move. Thus, the third scraper 17 can be moved sequentially to clean the inside of the collection frame 6. At the same time, the rotating disk 7 can be rotated to polish the wall surface through the synchronous wheel 21 and the synchronous belt 22.

[0062] Reference Figure 1 and Figure 8 Two L-shaped blocks 40 are rotatably connected to both sides of the base 1. Rollers 10 are fixedly connected to the bottom of the L-shaped blocks 40. An oblong hole 41 is opened on the inner wall of the L-shaped block 40. A nut block 42 is provided on the inner wall of the oblong hole 41. Two fixing blocks 43 are fixedly connected to both sides of the base 1. A screw 44 is rotatably connected between the two fixing blocks 43 on the same side. The two nut blocks 42 on the same side are threaded onto the screw 44. In the above technical solution, rotating the screw 44 can drive the two nut blocks 42 to move closer to each other. The movement of the nut blocks 42 can drive the L-shaped blocks 40 to rotate through the oblong hole 41 until one side of the L-shaped block 40 contacts the ground, which can fix the base 1 on the ground, making it easy to move and fix.

[0063] Reference Figures 4-6 The inner wall of the slurry frame 3 is rotatably connected to a second scraper 5. An arc-shaped plate 27 is fixedly connected to the side of the second scraper 5 near the slurry frame 3. A middle baffle 45 is fixedly connected to the bottom of the second scraper 5. The middle baffle 45 contacts the top of the first scraper 4. Both ends of the first scraper 4 are fixedly connected to side baffles 35. In the above technical solution, rotating the second scraper 5 can drive the arc-shaped plate 27 to rotate. When the arc-shaped plate 27 contacts the cement in the slurry frame 3, it can squeeze the cement into the first scraper 4 and smooth the wall surface through the first scraper 4.

[0064] Reference Figure 5 and Figure 6A lifting plate 33 is slidably connected to the inner wall of the mud frame 3. Rotating wheels 29 are rotatably connected to the bottom inner wall of the collection frame 6. Two connecting ropes 30 are fixedly connected to the top of the lifting plate 33. The other end of each connecting rope 30 passes around the rotating wheel 29 and is fixedly connected to the arc-shaped plate 27. Grooves 36 corresponding to the connecting ropes 30 are provided on both sides of the arc-shaped plate 27. Tension springs 34 are fixedly connected to the side baffles 35 on both sides of the other end of the second scraper 5. Two abutting blocks 31 that cooperate with the arc-shaped plate 27 are fixedly sleeved on the outer wall of the second rotating rod 26. In the above technical solution, the second rotating rod 26... The contact block 31 can be rotated. When the contact block 31 contacts the arc plate 27, it can rotate the arc plate 27 downward to contact the cement until the cement flows into the arc plate 27. When the contact block 31 moves away from the arc plate 27, the second scraper 5 is reset and rotated under the force of the tension spring 34, which drives the cement in the arc plate 27 to flow to the second scraper 5. The second scraper 5 can smooth the concave wall surface. While the arc plate 27 is rotating, the lifting plate 33 can be raised through the connecting rope 30 and the rotating wheel 29, which can drive the cement to rise, so that the cement can flow into the first scraper 4. The tension spring 34 can make the second scraper 5 automatically reset.

[0065] Reference Figure 7 The second scraper 5 has a rectangular groove 37 on the side away from the arc plate 27. A telescopic plate 38 is slidably provided on the inner wall of the rectangular groove 37. Multiple springs 39 are fixedly connected between the telescopic plate 38 and the rectangular groove 37. The telescopic plate 38 is in contact with the wall. In the above technical solution, the setting of the telescopic plate 38 prevents the second scraper 5 from hitting the wall when it rotates, so that it is always in contact with the wall.

[0066] A method for applying epoxy polymer-modified cement mortar includes the following steps:

[0067] S1. Push the device to one side of the wall so that the first scraper 4 and the second scraper 5 are in contact with the wall. Rotate the screw 44. The screw 44 can drive the two nut blocks 42 to move closer to each other. Through the setting of the waist-shaped hole 41, the two L-shaped blocks 40 can be driven to rotate relative to each other so that one side of the L-shaped block 40 contacts the ground. The device can be fixed to one side of the wall.

[0068] S2. Start the second motor 23. The second motor 23 can drive the first rotating rod 19 to rotate. The first rotating rod 19 drives one of the rotating disks 7 to rotate through the synchronous pulley 21 and the synchronous belt 22. The rotating disk 7 drives the scraper 14 to rotate, which can polish the wall. The rotating disk 7 can drive another rotating disk 7 to rotate in the opposite direction through the external toothed ring 13, which can polish the wall at the same time. The particles polished off fall into the collection frame 6 through the W-shaped dust pouring plate 12. The rotation of the first rotating rod 19 drives the conveying roller 20 to rotate. The rotation of the conveying roller 20 can drive the third scraper 17 to move. Thus, through the belt pulley 15 and the connecting belt 16, multiple third scrapers 17 are driven to move simultaneously. The movement of the third scrapers 17 can push the particles into the collection frame 6 for collection.

[0069] S3. Start the sludge pump assembly 32 to pump the prepared cement to the lifting plate 33 inside the sludge frame 3. Start the first motor 9. The first motor 9 can drive the second rotating rod 26 to rotate. The second rotating rod 26 can drive the sludge frame 3 and the collection frame 6 to move upward through the rack 24 and gear 25. The second rotating rod 26 can drive the contact block 31 to rotate. When the contact block 31 contacts the rectangular groove 37, it can drive the arc plate 27 to move. The movement of the arc plate 27 can drive the second scraper 5 to rotate inside the sludge frame 3. The rotation of the second scraper 5 can drive the middle baffle 45 to rotate. At the same time, the movement of the arc plate 27 can drive the lifting plate 33 to rise through the connecting rope 30 and the rotating wheel 29, which can drive the cement to rise. The cement can flow into the arc plate 27 and onto the first scraper 4.

[0070] S4. When the contact block 31 moves away from the arc plate 27, the second scraper 5 automatically resets under the force of the tension spring 34, causing the middle baffle 45 to rotate and contact the first scraper 4, closing one side of the first scraper 4. This allows the second scraper 5 to rotate back and forth, allowing the cement in the arc plate 27 to flow onto the second scraper 5. The rotation of the second scraper 5 can cause the telescopic plate 38 to contact the wall, allowing cement to be applied to the concave wall surface. As it continues to move upward, the cement on the first scraper 4 flows onto the wall surface, and the surface is smoothed by the upward movement of the first scraper 4.

They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
