Description

Technical Field

[0001] The invention belongs to the technical field of plate compactors, and in particular relates to a shockproof plate compactor. Background Art

[0002] A plate compactor is a device with vibration and compaction capabilities, mainly used to compact the ground. Common plate compactors are mainly powered by internal combustion engines. Their working principle is: the internal combustion engine drives the eccentric to rotate through the clutch and pulley, and the rotation of the eccentric drives the bottom plate to vibrate, thereby achieving the purpose of compacting the ground through the vibration of the bottom plate.

[0003] Since the flat plate compactor mainly drives the base plate to vibrate by rotating the eccentric, it is easy for the internal combustion engine, clutch and other components to vibrate synchronously with the vibration of the base plate during actual use. Such vibration will not only cause adverse effects on the internal combustion engine, clutch and other components, but also cause vibration damage to the user's arms and other parts, making the shock resistance and safety of the flat plate compactor poor.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

The one-way air intake pipes (203) are used to facilitate one-way air intake conduction for the flow-guiding shock-absorbing airbag (202). Both ends of the plurality of one-way air intake pipes (203) are fixedly connected with air intake dust filters (204). The air intake dust filters (204) prevent dust from being blocked for the one-way air intake pipe (203). A one-way air intake hole is provided in the one-way air intake pipe (203), and the diameter of one end of the one-way air intake hole located in the flow-guiding shock-absorbing airbag (202) is larger than the diameter of the other end. An air intake blocking ball (205) is arranged in the one-way air intake hole. The cooperation between the air intake blocking ball (205) and the one-way air intake hole enables air intake conduction and exhaust blocking for the one-way air intake pipe (203). A limit spring (206) is arranged between the air intake blocking ball (205) and the air intake dust filter (204). The limit spring (206) supports and limits the air intake blocking ball (205) through contraction and reset.

[0014] In one or more embodiments of the present invention, the one-way exhaust assembly includes a plurality of one-way exhaust pipes (207), and the plurality of one-way exhaust pipes (207) are staggeredly distributed with the one-way air intake pipe (203). The air in the flow-guiding shock-absorbing airbag (202) is discharged through the plurality of one-way exhaust pipes (207). Exhaust dust filters (208) are fixedly connected to both sides of the plurality of one-way exhaust pipes (207). The one-way exhaust holes are protected against blocking by the exhaust dust filters (208). One-way exhaust holes are provided in the plurality of one-way exhaust pipes (207), and the diameter of one end of the one-way exhaust hole located in the flow-guiding shock-absorbing airbag (202) is smaller than the diameter of the other end, and an exhaust blocking ball (209) is arranged in the one-way air intake hole.

A support spring (210) is arranged between the exhaust gas blocking ball (209) and the exhaust gas dust filter (208). The exhaust gas blocking ball (209) is supported and reset by the contraction and reset of the support spring (210).

[0015] In one or more embodiments of the present invention, the linkage tensioning assembly includes a tensioning cylinder (211). The tensioning cylinder (211) supports the tensioning piston (212) and performs pneumatic control. The tensioning piston (212) is slidably mounted in the tensioning cylinder (211). The tensioning piston (212) supports the wheel frame (214), and can synchronously lift the tensioning wheel (215) by lifting the tensioning piston (212). The tensioning piston (212) cooperates with the tensioning cylinder (211) to form a linkage air cavity. The lifting and lowering movement state of the tensioning piston (212) is adjusted and controlled by controlling the gas delivery state of the linkage air cavity. A connecting spring (213) is arranged in the linkage air cavity. The connecting spring (213) supports and resets the tensioning piston (212).

[0016] In one or more embodiments of the present invention, a wheel frame (214) is fixedly connected above the tensioning piston (212). The wheel frame (214) serves as an assembly limit for the tensioning wheel (215). One end of the wheel frame (214) located outside the tensioning cylinder (211) is rotatably connected to the tensioning wheel (215). The lifting of the tensioning wheel (215) serves as a tension limit for the synchronous belt (105). A linkage air pipe (216) is connected below the tensioning cylinder (211), and the two ends of the linkage air pipe (216) are respectively connected to the linkage air cavity and the guide-type shock-absorbing airbag (202). The linkage air pipe (216) serves to connect the flow-guiding shock-absorbing airbag (202) and the linkage air cavity, so that part of the air in the flow-guiding shock-absorbing airbag (202) can be transported to the linkage air cavity along the linkage air pipe (216) under the action of vibration, thereby facilitating the tensioning wheel (215) to be synchronously lifted and moved with the vibration and contraction of the flow-guiding shock-absorbing airbag (202), thereby ensuring the tensioning state of the synchronous belt (105) and improving the stability of the synchronous belt (105) in transmitting the drive pulley (103) and the transmission pulley (104).

[0017] In one or more embodiments of the present invention, a pair of buffer oil cylinders (301) are filled with hydraulic buffer oil, and the diameter of the damping oil guide hole close to the side of the cylinder piston rod (303) is smaller than the diameter of the other end. This facilitates the hydraulic buffer oil of the extrusion piston (302) to be in a state where the extrusion speed is greater than the recovery speed, thereby facilitating the shock absorption and buffering of the extrusion piston (302) through the circulation of the hydraulic buffer oil. A dust cover (304) is sleeved on the outer side of the cylinder piston rod (303). The dust cover (304) plays a role of dust protection for the cylinder piston rod (303), thereby avoiding the friction of the cylinder piston rod (303) caused by external dust. A hydraulic spring (305) is arranged in the dust cover (304), and the hydraulic spring (305) is sleeved on the outer side of the cylinder piston rod (303). The hydraulic spring (305) plays a role of supporting and resetting the extrusion piston (302) through the contraction and resetting of the hydraulic spring (305). A temperature control guide cavity is opened on the inner wall of the pair of buffer oil cylinders (301). The temperature of the buffer oil cylinder (301) can be easily regulated by conveying heat transfer fluid into the temperature control flow guiding cavity.

[0018] In one or more embodiments of the present invention, the vibration type liquid cooling assembly includes a liquid storage cylinder (306). The liquid storage cylinder (306) has the function of storing and limiting the heat transfer fluid. A delivery piston (307) is slidably mounted in the liquid storage cylinder (306), and a compression reflux chamber is formed between the bottom of the delivery piston (307) and the liquid storage cylinder (306). The compression reflux chamber is regulated by controlling the movement of the delivery piston (307), so as to facilitate the extrusion and delivery of the heat transfer fluid in the compression reflux chamber. A guide piston rod (308) is fixedly connected to the top of the delivery piston (307), and the guide piston rod (308) is slidably matched with the liquid storage cylinder (306). The guide piston rod (308) serves to connect the fixed connecting plate (309) and the delivery piston (307). A fixed connecting plate (309) is fixedly connected between the guide piston rod (308) and the internal combustion engine (101). The fixed connecting plate (309) is used to connect and fix the flow guide piston rod (308) and the internal combustion engine (101), so that the pair of flow guide piston rods (308) and the fixed connecting plate (309) can be used to dampen, support and limit the internal combustion engine (101).

[0019] In one or more embodiments of the present invention, a return spring (310) is sleeved on the outer side of the guide piston rod (308), and the return spring (310) is arranged between the fixed connecting plate (309) and the liquid storage cylinder (306). The delivery piston (307) is supported and reset by the contraction and reset of the return spring (310). A liquid adding pipe (311) and a liquid return pipe (312) are connected between the liquid storage cylinder (306) and the temperature control guide chamber, and the liquid adding pipe (311) is arranged below the liquid return pipe (312). The heat transfer fluid in the compression reflux chamber and the temperature control guide chamber can be discharged and refluxed under the action of the liquid adding pipe (311) and the liquid return pipe (312). By arranging the liquid adding pipe (311) below the liquid return pipe (312), the sufficiency of the heat transfer fluid in exchanging heat with the buffer oil cylinder (301) is improved.

The fixed connecting plate 309 connects and fixes the guide piston rod 308 and the internal combustion engine 101, so that the pair of guide piston rods 308 and the fixed connecting plate 309 can support and limit the internal combustion engine 101.

[0055] like Figures 7 and 8 As shown, a return spring 310 is sleeved on the outer side of the guide piston rod 308, and the return spring 310 is arranged between the fixed connecting plate 309 and the liquid storage cylinder 306. The delivery piston 307 is supported and reset by the contraction and reset of the return spring 310.

[0056] like Figures 7 and 8 As shown, a liquid adding pipe 311 and a liquid return pipe 312 are connected between the liquid storage cylinder 306 and the temperature control flow guiding cavity, and the liquid adding pipe 311 is arranged below the liquid return pipe 312. The heat transfer fluid in the compression reflux cavity and the temperature control flow guiding cavity can be discharged and refluxed under the action of the liquid adding pipe 311 and the liquid return pipe 312. By arranging the liquid adding pipe 311 below the liquid return pipe 312, the sufficiency of the heat transfer fluid in exchanging heat with the buffer oil cylinder 301 is improved.

[0057] like Figure 1 As shown, a pair of dustproof and heat dissipation mechanisms 4 are fixedly assembled on both sides of the guide-type shock-absorbing airbag 202 , and the dustproof and heat dissipation mechanisms 4 are used to provide dustproof and air-cooled heat dissipation protection for the buffer cylinder 301 .

[0058] like Figure 10 to Figure 11 As shown, the dustproof heat dissipation mechanism 4 includes a dustproof side plate 401, and the dustproof side plate 401 is fixedly assembled above the bottom plate 1. The dustproof side plate 401 plays a preliminary dustproof role for the buffer cylinder 301 and the guide type shock absorbing airbag 202.

[0059] Specifically, both sides of the dustproof side plate 401 are provided with compression exhaust chambers, and a heat dissipation piston 402 is slidably mounted in the compression exhaust chamber, so that the heat dissipation piston 402 can compress and guide the air in the compression exhaust chamber.

[0060] like Figure 10 to Figure 11 As shown, a heat dissipation spring 403 is fixedly connected to the lower part of the heat dissipation piston 402. The heat dissipation spring 403 supports and resets the heat dissipation piston 402 through contraction and reset.

[0061] like Figure 10 to Figure 11As shown, a connecting support rod 404 is fixedly connected to the top of the heat dissipation piston 402, and one end of the connecting support rod 404 located outside the dustproof side plate 401 is hinged to the assembly fixing plate 201. The connecting support rod 404 serves to connect the heat dissipation piston 402 and the assembly fixing plate 201, so that the connecting support rod 404 can assist in supporting and limiting the assembly fixing plate 201, thereby ensuring the stability of supporting and limiting the assembly fixing plate 201. At the same time, the heat dissipation piston 402 can be squeezed and limited by the connecting support rod 404.

[0062] A plurality of heat dissipation vents are provided on one side of the assembly fixing plate 201 close to the buffer oil cylinder 301, so that the air in the compressed exhaust cavity can be discharged through the heat dissipation vents, thereby playing the role of air cooling and heat dissipation for the buffer oil cylinder 301.

[0063] like Figures 7 to 9 As shown, the outer sides of several heat dissipation vents are attached with a one-way conductive film 405. Under the action of the one-way conductive film 405, the heat dissipation vents are in a state of exhaust conduction and air intake blockage, avoiding the risk of dust in the external environment blocking the heat dissipation vents.

[0064] Specifically, a liquid storage cavity is provided in the dustproof side plate 401, and a compression liquid rod 406 is slidably mounted in the liquid storage cavity, and one end of the compression liquid rod 406 located outside the liquid storage cavity is hinged to the assembly fixing plate 201. The reciprocating movement of the compression liquid rod 406 squeezes and guides the dust-reducing fluid in the liquid storage cavity.

[0065] Preferably, the dust reduction fluid can be water.

[0066] like Figure 1 As shown, a water tank 407 is fixedly connected to the outer side of the assembly fixing plate 201. The dust reduction fluid is stored in the water tank 407.

[0067] like Figure 1 As shown, a guide pipe 408 is connected between the water tank 407 and the liquid storage chamber, so that the dust reduction fluid in the water tank 407 can be transported to the liquid storage chamber along the guide pipe 408.

[0068] like Figure 1 to Figure 2 As shown, a spray plate 409 is fixedly connected to the outer side of the dustproof side plate 401, and multiple groups of evenly distributed spray nozzles 410 are fixedly connected to the outer side of the spray plate 409. The multiple groups of spray nozzles 410 are connected to the liquid storage chamber through the spray plate 409. The method of spraying the dust reduction fluid through the multiple groups of spray nozzles 410 can not only guide the dust reduction fluid in the liquid storage chamber, but also spray the dust generated by the vibration of the bottom plate 1.

[0069] like Figure 10 to Figure 11As shown, a pair of cooling air inlet cavities 411 are provided in the dustproof side plate 401, and the pair of cooling air inlet cavities 411 are arranged between the compression exhaust cavity and the liquid storage cavity, and the pair of cooling air inlet cavities 411 are both connected to the compression exhaust cavity. When the outside air flows through the cooling air inlet cavities 411, heat exchange is performed with the dust reduction fluid in the liquid storage cavity, thereby improving the effect of blowing and cooling the buffer oil cylinder 301.

[0070] like Figure 10 to Figure 11 As shown, a pair of cooling air inlet cavities 411 are fixedly connected with anti-blocking dust filter nets 412 above. The anti-blocking dust filter nets 412 play the role of anti-blocking and dust filtering protection for the cooling air inlet cavities 411.

[0071] During specific use, the eccentric 102 is fixedly assembled on the top of the base plate 1, and the internal combustion engine 101 is fixedly assembled on the top of the assembly fixing plate 201. The internal combustion engine 101 and the eccentric 102 are transmitted and coordinated through the driving pulley 103, the transmission pulley 104 and the synchronous belt 105. The internal combustion engine 101 drives the transmission pulley 104 to rotate so that the eccentric block in the eccentric 102 can rotate synchronously under the action of the driving pulley 103 and the synchronous belt 105, and the vibration of the base plate 1 is controlled by the rotation of the eccentric block in the eccentric 102.

[0072] When the bottom plate 1 vibrates and compacts the ground, the assembly fixing plate 201 is supported and limited by the guide-type shock-absorbing airbag 202, the cylinder piston rod 303, the fixed connecting plate 309, the connecting support rod 404 and the compressed liquid rod 406, and the guide-type shock-absorbing airbag 202 vibrates under the action of the assembly fixing plate 201 and the bottom plate 1. When the distance between the assembly fixing plate 201 and the bottom plate 1 is reduced, the air in the guide-type shock-absorbing airbag 202 can be transported to the linkage air cavity along the linkage air pipe 216. By transporting air to the linkage air cavity, the air in the linkage air cavity is compressed. The tensioning piston 212 is lifted by air, so that the tensioning wheel 215 can tension and support the synchronous belt 105; when the distance between the assembly fixing plate 201 and the base plate 1 becomes larger, the air in the linkage air cavity can flow back to the guide type shock-absorbing airbag 202 along the linkage air pipe 216, and the tensioning wheel 215 is reset synchronously with the resetting of the tensioning piston 212. Through the linkage between the tensioning wheel 215 and the guide type shock-absorbing airbag 202, the synchronous belt 105 can be in a tensioned state at all times, thereby ensuring the transmission stability of the synchronous belt 105.

[0073] At the same time, the flow-guiding shock-absorbing airbag 202 can provide shock-absorbing support to the assembly fixing plate 201 by means of one-way air intake through the one-way air intake pipe 203 and one-way exhaust through the one-way exhaust pipe 207, and can play a preliminary shock-absorbing role for the internal combustion engine 101. In addition, the air discharged from the one-way exhaust pipe 207 can be blown toward the buffer oil cylinder 301, and can assist in cooling the buffer oil cylinder 301.

[0074] Furthermore, a pair of self-cooling buffer support mechanisms 3 can be used to buffer and support the corners of the assembly fixing plate 201. During use, the assembly fixing plate 201 can be auxiliary buffered and limited by the hydraulic buffer oil flowing under the action of the damping oil guide hole. In addition, as the distance between the assembly fixing plate 201 and the bottom plate 1 changes, the guide piston rod 308 can drive the delivery piston 307 to squeeze the compression return chamber under the action of the assembly fixing plate 201, so that the heat transfer fluid can flow through the temperature control guide chamber under the action of the liquid adding pipe 311 and the liquid return pipe 312, so that the temperature of the buffer oil cylinder 301 can be controlled, ensuring the reliability of the shock absorbing support of the buffer oil cylinder 301.

[0075] Finally, the air in the compressed exhaust chamber can be discharged along the heat dissipation vents by squeezing the compressed exhaust chamber through the connecting support rod 404, thereby not only providing shock-absorbing support to the side of the assembly fixing plate 201, but also assisting in the heat dissipation of the buffer cylinder 301.

[0076] The reciprocating squeezing of the liquid storage chamber by the compression liquid rod 406 can not only perform hydraulic buffering and limiting on the assembly fixing plate 201, but also assist dust reduction on the bottom plate 1 by spraying the dust reduction fluid through the spray nozzle 410.
