[0004] The Chinese patent with the authorization announcement number CN202320899252.7 discloses a high-efficiency polishing mechanism, including a connecting plate and a polishing assembly installed on the connecting plate, wherein the connecting plate is a box structure with a box cover, and a driving gear is arranged in the box structure, and the driving gear is driven by the output shaft of an external reducer; the polishing assembly is provided with two groups, each group of polishing assemblies includes a driven gear, a driven shaft and a polishing disc, the driven gear is located in the box structure and is connected to the driven shaft by transmission, the driving gear drives the two driven gears to rotate in opposite directions at the same time through the transmission assembly, the polishing disc is installed at the bottom end of the driven shaft, and the polishing disc is a toothed structure, and the two polishing discs are meshed with each other. The utility model can solve the problem of continuous manual scraping in the existing slatted floor polishing process.

[0005] The existing slatted floor making equipment still has the following problems:

[0006] 1. During the production process of cement slatted floor, abrasives need to be sprayed, mainly to help increase the friction on the surface of the slatted floor and prevent animals from slipping on it. However, the existing abrasive spraying is basically done manually, which not only has low construction efficiency, but also has problems such as uneven distribution of abrasives, which will affect the wear resistance and other properties of the slatted floor surface.

[0007] 2. When using multiple grinding discs for polishing, since the grinding discs are in contact with the cement in a (hydraulic or pneumatic) telescopic form, when the grinding discs fall and contact the cement and move for polishing, the surface of the cement will produce a wave-like deformation due to the extrusion force, and the outer edge of the grinding disc will push the protruding cement out of the mold, resulting in problems such as inconsistent density of the cement slatted floor during the polishing process.

[0008] 3. When polishing the slatted floor, some excess cement will be scraped to the outside of the mold. At the production site of the slatted floor, a large amount of cement will be scattered around the mold, which not only causes a waste of cement, but also wastes manpower to handle it.

[0024] Compared with the existing known technologies, the technical solution provided by the present invention has the following significant effects:

[0025] 1. Through the settings of storage barrel, material distribution barrel, material distribution bar and material discharge chute, when the abrasive enters the material distribution barrel, the abrasive is evenly distributed in the material distribution barrel. When the abrasive needs to be sprayed midway, it is only necessary to rotate the material distribution bar. The abrasive dropped each time is more evenly distributed and does not require manual throwing. It not only improves the continuity of the production of the slatted floor and the work efficiency, but also further improves the wear resistance and other properties of the surface of the slatted floor.

[0026] 2. Through the settings of screen, connecting rod, wave plate and material balancing motor, when the material balancing motor drives the material balancing bar to rotate, the wave block arranged on the wave plate drives the connecting rod to move back and forth. When the abrasive falls on the screen, the abrasive is like a reciprocating screen. With the movement of the walking unit and the rotation of the material balancing motor, the abrasive can be more evenly distributed on the surface of the slatted floor, further improving the uniformity of the abrasive and the wear resistance of the slatted floor.

[0027] 3. Through the settings of the air duct, dust suction pipe, material distribution pipe, air pressure motor and dust hood, the air pressure motor and the material distribution motor are started synchronously. When the powdered abrasive falls on the surface of the slatted floor and dust is generated, the high-speed airflow formed in the air duct makes the material distribution pipe and the dust suction pipe in a relatively negative pressure state. The dust enters the dust suction pipe and the material distribution pipe through the dust suction hood. After being blocked by the filter plate, the abrasive passes through the arc-shaped lower barrel and enters the storage barrel, thereby realizing the control of dust. It can not only reduce the pollution to the environment and the damage to the workers' bodies, but also can recycle and reuse the abrasive.

[0028] 4. Through the settings of transmission bevel gears, conduction bevel gears, conduction rods and spur gears, when the walking unit drives the mounting platform to move, the spur gears mesh with the racks, and the transmission rods, transmission bevel gears and conduction bevel gears transmit the pre-pressing rollers to actively rotate, eliminating the problem of slipping and enhancing the pressing effect of the pre-pressing rollers on cement.

[0029] 5. Through the settings of guide plates, recycling barrels, scraping components, connecting plates and scraping strips, excess cement and other materials are directly scraped onto the recycling barrel or guide plates. Since the guide plates have a certain curvature and cooperate with the reciprocating scraping strips, excess cement will fall directly into the recycling barrel, which is not only convenient for collection, but also greatly reduces the workload of workers.

DETAILED DESCRIPTION

[0046] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0047] Depend on Figures 1 to 9The present invention comprises a support frame 1 placed on a horizontal plane, a walking unit 2 placed on the support frame 1, a polishing assembly arranged below the walking unit 2, a vibration table 3 placed on a horizontal plane and below the polishing assembly, and a mold 4. The mold 4 is located on the vibration table 3, and the vibration table 3 drives the mold 4 to vibrate at a high frequency. The support frame 1 comprises two symmetrically distributed support beams and a cross beam fixedly connected to the two support beams, and the cross beam is composed of two symmetrically distributed cross bars. The walking unit 2 comprises a walking frame located between the two cross bars, and walking wheels are respectively arranged on both sides of the walking frame. A walking motor is arranged above the walking frame, and the walking motor is connected to one of the walking wheels through a sprocket transmission structure. The vibration table 3 has a high-frequency vibration function. When the mold 4 is placed on the vibration table 3, the worker fills cement into the mold 4. Under the action of high-frequency vibration, the cement is more evenly distributed in the mold 4. The polishing assembly includes a mounting platform 5, and two symmetrically distributed telescopic rods 6 are arranged between the mounting platform 5 and the walking unit 2. The telescopic rod 6 is hydraulically controlled, specifically a hydraulic telescopic rod. The hydraulic telescopic rod is externally connected to a pressure supply device. A grinding motor 7 is arranged on the mounting platform 5. Grinding discs 8 are arranged on the left and right sides of the mounting platform 5, respectively. The grinding motor 7 is connected to the two grinding discs 8 through a synchronous belt transmission structure, and tensioning wheel assemblies are arranged on both sides of the synchronous belt to assist the synchronous belt in transmission. A sandblasting assembly located between the two grinding discs 8 is arranged at the bottom of the mounting platform 5. Through the arrangement of the telescopic rod 6, the grinding motor 7 and the grinding disc 8, the telescopic rod 6 drives the mounting platform 5 to move downward until the grinding disc 8 contacts with the material, the grinding motor 7 is started, and the grinding disc 8 grinds the material. The two grinding discs 8 have higher efficiency.

[0048] Taking into account that the existing abrasive spraying is basically carried out by manual spraying, not only the construction efficiency is low, but also there are problems such as uneven distribution of abrasive, which affects the wear resistance and other properties of the surface of the slatted floor, further supplementing the sandblasting assembly is that the sandblasting assembly includes a storage barrel 9 placed in the mounting platform 5, which stores abrasives inside, and a material distribution barrel 10 is arranged below the mounting platform 5, and a material guide plate 11 is arranged between the material distribution barrel 10 and the mounting platform 5, and the material distribution barrel 10 is connected to the mounting platform 5 through the material guide plate 11, and the abrasive in the storage barrel 9 enters the material distribution barrel 10 through the material guide plate 11, and a material distribution strip 12 is coaxially rotated in the material distribution barrel 10, and the material distribution strip 12 is formed by a plurality of material distribution plates evenly distributed around the circumference, and the material distribution strip 12 A plurality of silos of the same area are formed between the material balancing barrel 10, a material discharge trough 13 is provided at the bottom of the material balancing barrel 10, connecting shafts penetrating the material balancing barrel 10 are respectively provided at both ends of the material balancing strip 12, and a material balancing motor 15 is coaxially provided on one side of the connecting shaft. Through the material storage barrel 9, the material balancing barrel 10, the material balancing strip 12 and the material discharge trough 13, when the abrasive enters the material balancing barrel 10, the abrasive is evenly distributed in the material balancing barrel 10. When the abrasive needs to be sprayed midway, it is only necessary to rotate the material balancing strip 12. The abrasive that falls each time is more evenly distributed, and no manual throwing is required, which not only improves the continuity of the production of the slatted floor and the work efficiency, but also further improves the wear resistance and other properties of the surface of the slatted floor.

[0049] Taking into account the problem of excessive abrasive aggregation in the way that the abrasive directly falls on the surface of the slatted floor after passing through the material-leveling strip 12, it is further supplemented to the sandblasting assembly that a screen 16 that slides forward and backward is provided in the feed trough 13, and connecting rods 17 that penetrate the material-leveling barrel 10 are fixed to the front and rear sides of the screen 16, respectively, and a wave plate 18 is coaxially provided on the connecting shaft, and a connecting groove is provided on the wave plate 18, and the end of the connecting rod 17 away from the screen 16 slides in the connecting groove, and the wave plate 18 is a circular structure, and a plurality of circumferentially evenly distributed wave blocks are provided at the outer edge, and the changing trajectory of the connecting groove Consistent with the changing trajectory of the wave block, when the wave disk 18 rotates, the connecting rod 17 moves back and forth driven by the connecting groove and the wave disk 18. Through the settings of the screen 16, the connecting rod 17, the wave disk 18 and the material balancing motor 15, when the material balancing motor 15 drives the material balancing bar 12 to rotate, the wave block arranged on the wave disk 18 drives the connecting rod 17 to move back and forth. When the abrasive falls on the screen 16, accompanied by the movement of the walking unit 2 and the rotation of the material balancing motor 15, the abrasive can be more evenly distributed on the surface of the manure-slatted floor, thereby further improving the uniformity of the abrasive and improving the wear resistance of the manure-slatted floor.

[0050] refer to Figures 6 to 11As shown, considering that abrasives are thrown and there is a lot of dust, there will be a short period of dust when the grinding disc 8 just comes into contact with the grinding disc 8. In order to avoid environmental pollution caused by dust and physical damage to workers, the left and right sides of the storage barrel 9 are provided with abrasive recovery components, and the abrasive recovery components include a wind tube 19 fixedly connected to the storage barrel 9, a fan 20 is coaxially arranged on one side of the wind tube 19, and a material distribution pipe 21 is fixedly connected to one side of the wind tube 19. Here, the distribution pipe 21 and the wind tube 19 use Bernoulli's principle. The pressure is small where the wind speed is high. When there is a large wind force in the wind tube 19, the distribution pipe 21 will generate a corresponding suction force to enter the wind tube 19. The distribution pipe 21 is connected to the wind tube 19 and a filter plate 22 is obliquely arranged in the distribution pipe 21. When the dust abrasive enters the distribution pipe 21, it is filtered and blocked by the filter plate 22. The side of the distribution pipe 21 away from the wind tube 19 is provided with a plurality of dust suction pipes 23 distributed at equal intervals. The plurality of dust suction pipes 23 pass through one end of the mounting platform 5 and are fixed with a dust suction hood 24. A wind pressure motor 25 is arranged above the material storage barrel 9. The wind pressure motor 25 is connected to the fans 20 in the two abrasive components through a sprocket transmission structure. An arc-shaped discharge barrel 26 connected to the material storage barrel 9 is arranged below the material distribution pipe 21. Through the arrangement of the wind tube 19, the dust suction pipe 23, the material distribution pipe 21, the wind pressure motor 25 and the dust suction hood 24, the wind pressure motor 25 and the material distribution motor 1 5 is started synchronously. When the powdered abrasive falls on the surface of the slatted floor and generates dust, the high-speed airflow formed in the air duct 19 makes the inside of the material distribution pipe 21 and the dust suction pipe 23 in a relatively negative pressure state. The dust passes through the dust suction hood 24 and enters the dust suction pipe 23 and the material distribution pipe 21. After being blocked by the filter plate 22, the abrasive passes through the arc-shaped lower barrel 26 and enters the storage barrel 9. In this way, the dust can be controlled, which can not only reduce the pollution to the environment and the damage to the workers' bodies, but also can recycle the abrasive.

[0051] In order to strengthen the relative negative pressure inside the distribution pipe 21 and the dust suction pipe 23, the structure inside the wind tube 19 is further supplemented by providing a plurality of equally spaced reducing blocks inside the wind tube 19, and the reducing blocks divide the wind tube 19 into a plurality of equally spaced diffusers 27 and throats 28, wherein the inner diameter of the throat 28 is smaller than the inner diameter of the diffuser 27, and the plurality of dust suction pipes 23 are respectively connected to the corresponding throats 28. Based on Bernoulli's principle and the continuity equation, the Venturi tube can be referred to. When the dust suction pipe 23 corresponds to the throat 28, the gas flow rate in the dust suction pipe 23 reaches an optimum, thereby further improving the dust absorption efficiency of the abrasive recovery assembly.

[0052] refer to Figures 6 to 10As shown, considering that the filter plate 22 is prone to clogging when the abrasive recovery component is used for a long time, the two feed pipes 21 are each provided with a first reciprocating screw 30 that is consistent with the length direction of the feed pipe 21, and a scraper 31 is slidably connected to the first reciprocating screw 30, and the scraper 31 contacts the windward surface of the filter plate 22. One end of the first reciprocating screw 30 passes through the feed pipe 21 and is connected to the fan 20 through a belt drive structure. Through the first reciprocating screw 30 and the scraper 31, the wind pressure motor 25 rotates to drive the first reciprocating screw 30 to rotate. At this time, the scraper 31 scrapes off the abrasive accumulated on the filter plate 22 to avoid problems such as clogging of the filter plate 22.

[0053] Taking into account the problem of uneven distribution of abrasives when the storage barrel 9 is added and when the recovered abrasives enter the storage barrel 9, which affects the uniform discharge of the material balancing barrel 10, a second reciprocating screw 32 is arranged in the storage barrel 9, and a combing plate 33 is threadedly connected to the second reciprocating screw 32, and the side wall of the combing plate 33 is in contact with the inner wall of the storage barrel 9. The second reciprocating screw 32 is connected to the air pressure motor 25 through a belt drive structure. Through the second reciprocating screw 32, the combing plate 33 and the air pressure motor 25, the air pressure motor 25 rotates, and the second reciprocating screw 32 rotates to drive the combing plate 33 to move back and forth in the storage barrel 9, so that the material distribution inside the storage barrel 9 is more uniform.

[0054] refer to Figure 3 and Fig.12 As shown, considering that when the grinding disc 8 falls and contacts with the cement and moves for grinding, the surface of the cement will produce a waveform-like deformation due to the extrusion force, the outer edge of the grinding disc 8 has an extrusion force on the protruding cement, and part of the cement is pushed out of the mold 4, resulting in problems such as inconsistent density of the cement slatted floor during the grinding process. Pre-pressing components are respectively provided on the left and right sides of the mounting platform 5, and the pre-pressing components include a mounting plate 34 fixedly connected to the mounting platform 5, and a pre-pressing roller 35 sliding up and down is provided on the mounting plate 34. The pre-pressing roller 35 is connected to the mounting plate 34 through a spring assembly, and the pre-pressing roller 35 pre-presses cement and other materials to prevent the edge of the grinding disc 8 from directly scraping the protruding cement outside the mold 4;

[0055] In order to prevent the pre-pressing roller 35 from slipping, during the slipping process, the pre-pressing roller 35 will also push the protruding part of the cement out of the mold 4. A transmission bevel gear 36 is coaxially fixed to one end of the pre-pressing roller 35. The transmission bevel gear 36 is meshed with a conduction bevel gear 37. The conduction bevel gear 37 is coaxially fixed with a conduction rod 38. It is necessary to supplement the structure of the conduction rod 38 that the conduction rod 38 is composed of a plurality of telescopic sleeves, and the telescopic sleeves and the telescopic holes are both polygonal structures. This does not affect the normal extension and contraction of the conduction rod 38, nor does it affect the transmission between the spur gear 39 and the conduction bevel gear 37. In order to improve the stability of the conduction rod 38, the crossbeam opening of the support frame 1 A slot is provided, and the top of the transmission rod 38 is rotatably connected to a stabilizing plate, one end of the stabilizing plate slides in the slot, and a spur gear 39 is coaxially fixed to the end of the transmission rod 38 away from the transmission bevel gear 37, and a rack 40 meshing with the spur gear 39 is fixed on the support frame 1. Through the transmission bevel gear 36, the transmission bevel gear 37, the transmission rod 38 and the spur gear 39, when the walking unit 2 drives the mounting platform 5 to move, the spur gear 39 meshes with the rack 40, and through the transmission of the transmission rod 38, the transmission bevel gear 36 and the transmission bevel gear 37, the pre-pressing roller 35 becomes actively rotated, and there is no problem of slipping. At the same time, the pressing effect of the pre-pressing roller 35 on the cement will be enhanced.

[0056] refer to Figure 1 and Fig.14 As shown, when the slatted floor is polished, some excess cement will be scraped off to the outside of the mold 4. At the production site of the slatted floor, a large amount of cement will be scattered around the mold 4, which not only causes a waste of cement, but also wastes manpower to process it. The front and rear sides of the mold 4 are respectively fixed with telescopic guide plates 41, and the guide plates 41 are arched structures with a high middle and low sides. Recovery buckets 42 are respectively placed on the left and right sides of the vibration table 3;

[0057] The guide plates 41 are each provided with a scraping assembly, which includes a connecting plate 43 that slides left and right on the guide plate 41, and two left-right symmetrical scraping strips 44 are provided on the connecting plate 43, and the scraping strips 44 are connected to the connecting plate 43 by a spring, and the scraping strips 44 are of a "boomerang"-like structure. Through the arrangement of the guide plate 41, the recovery bin 42, the scraping assembly, the connecting plate 43 and the scraping strips 44, excess cement and other materials are directly scraped onto the recovery bin 42 or the guide plate 41. Since the guide plate 41 has a certain curvature, with the reciprocating scraping strips 44, excess cement will directly fall into the recovery bin 42, which is not only convenient for collection, but also greatly reduces the labor of workers.

[0058] refer to Figure 3 and Fig.13As shown, considering the different width specifications of the slatted floor, in order to improve the versatility of the sandblasting assembly, slide bars 45 are fixed on both sides of the material balancing barrel 10, and width adjustment components are respectively provided at the front and rear ends of the slide bar 45. The width adjustment component includes an adjustment plate 46 located below the feed chute 13, and connecting ears 47 are fixed on both sides of the adjustment plate 46, and the connecting ears 47 are slidably connected to the slide bar 45;

[0059] An adjusting rod 48 is fixed to the connecting ear 47, and an adjusting cylinder 49 is slidably connected to the adjusting rod 48. The adjusting cylinder 49 is connected to the adjusting rod 48 by a spring, and a telescopic frame 50 is fixed to the end of the adjusting cylinder 49 away from the adjusting rod 48, and a hook 51 is fixed to the end of the telescopic frame 50 away from the adjusting cylinder 49, and a hanging plate 52 matching the hook 51 is fixed to the connecting plate 43. The width adjustment assembly is combined with the scraping assembly through the settings of the sliding rod 45, the adjusting plate 46, the adjusting rod 48 and the adjusting cylinder 49. When in use, the worker hangs the hook 51 on the hook 51. When the walking unit 2 is started, the width adjustment assembly will also drive the scraping assembly to reciprocate. At the same time, when the hook 51 is hung on the hanging plate 52, the gap between the two adjustment plates 46 is the width distance suitable for the slatted floor.

[0060] In order to further improve the stability of the scraper strip 44 moving on the guide plate 41, the guide plate 41 includes a bearing portion 53 and a limiting portion 54, the scraper strip 44 is in contact with the bearing portion 53, a track is formed between the limiting portion 54 and the bearing portion 53, and a limiting wheel 55 is provided on one side of the connecting plate 43 close to the track, and the limiting wheel 55 is located in the track.

[0061] When the present invention is used:

[0062] First, the mold 4 is placed on the vibration table 3, and the worker fills the cement into the mold 4. The telescopic rod 6 drives the mounting table 5 to move downward until the grinding disc 8 contacts the material, and the grinding motor 7 is started, and the grinding disc 8 grinds the material;

[0063] Then, when the mounting platform 5 descends, the pre-pressing roller 35 pre-presses the cement and other materials. When the traveling unit 2 drives the mounting platform 5 to move, the spur gear 39 meshes with the rack 40, and the pre-pressing roller 35 is driven by the transmission rod 38, the transmission bevel gear 36 and the transmission bevel gear 37, so that the pre-pressing roller 35 rotates actively without the problem of slipping. At the same time, the pressing effect of the pre-pressing roller 35 on the cement is enhanced.

[0064] At the same time, the worker hangs the hook 51 on the hook 51. When the walking unit 2 is started, the width adjustment component will also drive the scraping component to move back and forth. Since the guide plate 41 has a certain curvature, in conjunction with the reciprocating scraping strip 44, the excess cement will directly fall into the recovery bucket 42;

[0065] Secondly, when it is necessary to spray the abrasive midway, it is only necessary to rotate the material-leveling strip 12. The abrasive that falls each time is more evenly distributed, and there is no need for manual throwing. It should be noted that when the material-leveling motor 15 drives the material-leveling strip 12 to rotate, the wave block provided on the wave plate 18 drives the connecting rod 17 to reciprocate. When the abrasive falls on the screen 16, accompanied by the movement of the walking unit 2 and the rotation of the material-leveling motor 15, the abrasive can be more evenly distributed on the surface of the slatted floor.

[0066] Finally, the wind pressure motor 25 and the material distribution motor 15 are started synchronously. When the powdered abrasive falls on the surface of the manure-leaning floor and dust is generated, the high-speed airflow formed in the wind tube 19 makes the distribution pipe 21 and the dust suction pipe 23 in a relatively negative pressure state. The dust enters the dust suction pipe 23 and the distribution pipe 21 through the dust hood 24. After being blocked by the filter plate 22, the abrasive passes through the arc-shaped discharge barrel 26 and enters the storage barrel 9.

[0067] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
