Description

Technical Field

[0001] The invention belongs to the technical field of rammers, and in particular relates to a dustproof rammer. Background Art

[0002] The impact rammer is a compaction machine that uses impact and vibration to compact backfill soil in layers. It has the advantages of strong power, flexible operation, and high construction efficiency. It is often used in the construction field to compact loose materials such as clay, sand, and gravel. When the impact rammer is used to ram some dusty ground, it is easy to cause the dust on the ground to fly, thereby causing greater pollution, which not only affects the operation of the staff, but also causes harm to the health of the construction workers.

[0003] At present, in order to reduce the flying of dust, spray dust removal is usually performed when the impact rammer is used. However, this method has high limitations. When the land to be compacted cannot be added with water, this spray dust reduction cannot be used, which will still cause dust to fly, and spray dust reduction will also affect construction workers.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] like Figure 1-Figure 11 As shown, a dustproof rammer in one embodiment of the present invention comprises: a rammer body 1, a dust suppression mechanism 2, a dustproof covering mechanism 3 and a collecting mechanism 4.

[0022] like Figure 1 As shown, a pressing assembly 101 is installed on the rammer body 1, and an impact plate 102 is fixed to one end of the pressing assembly 101 away from the rammer body 1 for impact compacting the soil. The impact plate 102 can increase the compaction area, thereby improving the soil compaction efficiency.

[0023] like Figure 1As shown, a pair of support arms 103 are fixed on the outer wall of the rammer body 1, which are used to fix the rammer body 1 and facilitate the gripping of the staff for easy operation. A control ring handle 104 is fixed on the upper end of the pair of support arms 103. A plurality of reinforcing rods 105 are installed on the control ring handle 104 to improve the strength of the control ring handle 104, avoid the control ring handle 104 from breaking or bending, and thus facilitate the staff to maintain the stability of the rammer body 1.

[0024] like Figure 1-Figure 7 As shown, the dust suppression mechanism 2 is installed on the rammer body 1, and the dust suppression mechanism 2 includes a dust removal filter frame 201, which is used to provide space for filtering dust, so that the gas can be filtered during the transportation process, and the dust removal filter frame 201 is sleeved on the outer wall of the rammer body 1. A support partition 202 is fixed in the dust removal filter frame 201, which is used to support multiple filter screens 203, so that the gas needs to be filtered by the filter screen 203 before floating upward, so that the dust in the gas can fall.

[0025] like Figure 1-Figure 7 As shown, a plurality of evenly distributed filter screens 203 are installed on the support baffle 202 for filtering the gas so that dust will not spread outward. A dust removal ball 213 is arranged in the filter screen 203 for irregularly bumping in the filter screen 203 so that the dust filtered by the filter screen 203 can fall, and then the dust can fall into the collection bucket 402 for easy collection and cleaning.

[0026] Specifically, a guide inclined plate 204 is installed between the dust removal and filtering frame 201 and the rammer body 1 to guide the dust to fall into the fixed frame 401, thereby facilitating the collection and cleaning of the dust.

[0027] In addition, a plurality of dust suction ducts 205 are installed on the guide inclined plate 204 , and the dust suction ducts 205 are arranged to penetrate the guide inclined plate 204 , so that the dust suction ducts 205 can continuously transport gas upwards, and because there is continuously gas transported upwards in the dust suction ducts 205 , dust will not fall downwards from the dust suction ducts 205 .

[0028] like Figure 1-Figure 3 As shown, an air suction protection frame 206 is provided above the rammer body 1, which is used to facilitate the installation of the negative pressure fan 207, prevent the negative pressure fan 207 from shaking and falling off, and facilitate the delivery of gas. A rubber pad 210 is fixedly connected between the air suction protection frame 206 and the rammer body 1, which is used to protect the negative pressure fan 207, so that the negative pressure fan 207 will not be directly subjected to rigid impact when the rammer body 1 jumps up and down, thereby improving the service life of the device.

[0029] like Figure 1-Figure 3As shown, a negative pressure fan 207 is provided in the air suction protection frame 206 to drive the gas flow, so that one end of the plurality of dust suction ducts 205 generates suction force to quickly suck away the stirred dust, thereby ensuring the use environment of the rammer body 1 and preventing the dust from causing harm to the staff. A protective screen 208 is installed on the air suction protection frame 206 to protect the negative pressure fan 207, reduce the probability of the negative pressure fan 207 being damaged, and thus increase the service life of the device.

[0030] In addition, a plurality of connecting elbows 209 are fixedly connected between the air intake protection frame 206 and the dust removal filter frame 201 for conveying gas, so that the gas can be conveyed from the dust removal filter frame 201 to the air intake protection frame 206 and then discharged upward.

[0031] like Figure 1-Figure 9 As shown, a plurality of supporting vertical bars 211 are fixed on the inner wall of the filter screen cylinder 203, which are used to support and fix a plurality of side oblique spikes 212 to prevent the side oblique spikes 212 from falling off. A plurality of evenly distributed side oblique spikes 212 are fixed on the supporting vertical bars 211, which are used to assist the dust removal ball 213, so that the dust removal ball 213 can be tilted and hit, and then the dust removal ball 213 can be irregularly hit in the filter screen cylinder 203, so that the dust filtered on the filter screen cylinder 203 can be shaken off, which is convenient for collection and cleaning.

[0032] Specifically, a supporting screen plate 214 is fixed to the upper end of the filter screen cylinder 203, and a plurality of evenly distributed top bevel teeth 215 are installed on the supporting screen plate 214 for further filtering the gas and impurities, thereby improving the filtering effect of the gas and assisting the dust removal balls 213 to perform irregular impact.

[0033] like Figure 5 As shown, a plurality of dust exhaust grooves 216 are formed on the dust removal filter frame 201 to facilitate dust to enter the collection bucket 402 , thereby facilitating collection and cleaning and preventing dust from spreading outward and accumulating in the dust removal filter frame 201 .

[0034] like Figure 1-Figure 11 As shown, the dustproof cover mechanism 3 is installed on one side of the dust removal filter frame 201. The dustproof cover mechanism 3 includes a plurality of dustproof shielding rotating plates 301, which are used to rotate to a horizontal position, so as to shield dust when the device is in use. The plurality of dustproof shielding rotating plates 301 are interconnected with dustproof shielding cloths 312 to assist in shielding dust. A retractable shielding plate 302 is inserted into the dustproof shielding rotating plate 301 to increase the area of ​​shielding dust and improve the use effect of the device.

[0035] like Figure 1-Figure 11As shown, a plurality of grooves are chiseled on the telescopic shielding plate 302, and a pushing spring 303 is arranged in the groove for pushing the telescopic shielding plate 302, so that after the dustproof shielding rotating plate 301 is rotated to a horizontal state, the telescopic shielding plate 302 is pushed out by the pushing spring 303, thereby increasing the dust shielding effect, and the two ends of the pushing spring 303 are fixedly connected to the dustproof shielding rotating plate 301 and the telescopic shielding plate 302 respectively.

[0036] like Figure 10-11 As shown, the upper rotation of the dust shield rotating plate 301 is connected with a pair of supporting bent rods 306, through which the control pull rod 307 can be fixed, so that the control pull rod 307 cannot rotate, but can be telescopically slid, so that the negative pressure fan 207 can drive the movement of multiple limit racks 309, thereby driving the fixed rack 308 and the limit rack 309 to engage and separate with each other.

[0037] like Figure 1-Figure 6 As shown, a plurality of fixing screws 304 are fixed on the outer wall of the rammer body 1, which are used to enable the limiting screw sleeve 305 to move when it rotates. The fixing screw 304 is threadedly connected with the limiting screw sleeve 305, and a hole matching the limiting screw sleeve 305 is drilled at one end of the telescopic shielding plate 302. The limiting screw sleeve 305 is inserted into the hole on the telescopic shielding plate 302, so that the telescopic shielding plate 302 and the dustproof shielding rotating plate 301 cannot rotate, achieving a fixing effect, thereby reducing the space occupied when the device is not in use, and preventing the dustproof shielding rotating plate 301 from shaking.

[0038] like Figure 1-Figure 11 As shown, a plug hole is drilled on the dust shield rotating plate 301 for controlling the insertion of the pull rod 307. A control pull rod 307 is inserted in the plug hole for supporting multiple limit racks 309 and driving the limit racks 309 to move. Multiple evenly distributed fixed racks 308 are installed on the side wall of the plug hole. The dust shield rotating plate 301 cannot be rotated by mutual engagement between 30 and the limit racks 309. When the control pull rod 307 is pulled so that the limit rack 309 is no longer mutually engaged with the fixed rack 308, the dust shield rotating plate 301 can be rotated, and then the dust shield rotating plate 301 is adjusted to a horizontal position to facilitate dust shielding. The control pull rod 307 is installed with a limit rack 309 that meshes with multiple fixed racks 308.

[0039] Among them, a limiting ring sleeve 310 is also fixed on the control pull rod 307, which is used to support the fixed support spring 311. A support spring 311 is connected between the limiting ring sleeve 310 and the dust-proof shielding rotating plate 301, which is used to push the limiting ring sleeve 310, so that the control pull rod 307 drives the limiting rack 309 and the fixed rack 308 to engage with each other without falling off, thereby making the dust-proof shielding rotating plate 301 unable to rotate.

[0040] like Figure 1-Figure 6 As shown, multiple collecting mechanisms 4 are installed on the outer wall of the dust removal filter frame 201, and the collecting mechanisms 4 are used to collect the filtered dust and impurities. The collecting mechanism 4 includes a fixed frame 401, which is used to conveniently place a collecting bucket 402, so as to facilitate the collection and cleaning of dust. The collecting bucket 402 and a sealing gasket 403 are arranged in the fixed frame 401. The collecting bucket 402 is used to collect the fallen dust, and the sealing gasket 403 is used to achieve a sealing effect to prevent dust and gas from leaking.

[0041] In addition, a plurality of connecting rods 404 are fixedly connected between the collecting bucket 402 and the sealing gasket 403 for conveniently driving the collecting bucket 402 to move, and the dust exhaust groove 216 connects the dust removal filter frame 201 and the fixed frame 401 .

[0042] When in use, before the rammer body 1 is used, the control rod 307 is first pulled so that the control rod 307 drives the plurality of limit racks 309 to no longer engage with the fixed racks 308. Fig.11 As shown, the limiting screw sleeve 305 is rotated again, and the limiting screw sleeve 305 is threadedly connected with the fixing screw 304 through the limiting screw sleeve 305, so that the limiting screw sleeve 305 is no longer inserted into the hole on the telescopic shielding plate 302, and then the dust-proof shielding rotating plate 301 and the telescopic shielding plate 302 are rotated. At this time, the telescopic shielding plate 302 can be extended out of the dust-proof shielding rotating plate 301 through the pushing of the pushing spring 303, thereby increasing the shielding area, and after the dust-proof shielding rotating plate 301 is rotated horizontally, the control pull rod 307 is inserted again, so that the fixed rack 308 and the limiting rack 309 are meshed with each other, and the dust-proof shielding rotating plate 301 cannot be rotated at this time, thereby achieving a fixing effect; Then, after the negative pressure fan 207 is started, the rammer body 1 can be used to work. When impacting the land, dust will be raised. After the negative pressure fan 207 is started, air can be sucked through the connecting elbow 209, and then the stirred dust is sucked through the dust removal filter frame 201 and the dust suction duct 205, and then transported into the dust removal filter frame 201, filtered by the filter screen 203, enter the suction protection frame 206, and finally discharged upward; The rammer body 1 will jump up and down when in use, thereby driving the dust removal ball 213 to collide in the filter screen cartridge 203, and with the assistance of multiple side inclined spikes 212 and top inclined teeth 215, the dust removal ball 213 can collide irregularly, thereby causing the dust filtered off the filter screen cartridge 203 to fall off, and then guided by the guide inclined plate 204, the dust can gradually slide into the collection bucket 402, thereby facilitating collection and cleaning, and allowing the filter screen cartridge 203 to be used continuously without disassembly, cleaning or replacement.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
