Description

Technical Field

[0001] This invention relates to the field of engineering machinery, and in particular to a new energy-powered plate compactor. Background Technology

[0002] Small construction machinery mainly refers to hand-held, non-self-propelled road construction equipment, such as concrete vibrators, road compactors, cutters, crushers, milling machines, and pavers. Single-cylinder, low-power gasoline engines are commonly used in this type of small construction machinery to provide power.

[0003] Vibratory plate compactors are mainly suitable for compacting materials with low adhesion and friction between particles, such as river sand, gravel, and asphalt. In daily life, internal combustion plate compactors are often needed in road repair and other work situations.

[0004] However, carbon emissions are unavoidable in the process of converting chemical energy into mechanical energy through fuel, and the more powerful the engine, the greater the carbon emissions. With climate change becoming increasingly serious, various sectors are advocating for green energy; therefore, developing green new energy small construction machinery to replace traditional fuel-powered small construction machinery is particularly important. Summary of the Invention

[0005] In view of the shortcomings of existing technologies, the purpose of this invention is to provide a new energy-powered plate compactor that has energy-saving and environmental protection effects.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a new energy power plate compactor, comprising:

[0007] The base plate has both ends that curve upwards and are designed to contact the ground.

[0008] A seat plate is located above the base plate, and its four corners are connected to the base plate via vibrators;

[0009] The vibration chamber is mounted on the base plate.

[0010] The motor is mounted on the base plate and connected to the vibration box via a belt;

[0011] The battery compartment is mounted on the base plate and connected to the motor;

[0012] A protective frame is mounted on the base plate and covers the motor and the battery compartment.

[0013] By adopting the above technical solution, when the plate compactor is working, the lithium battery in the battery compartment provides power and drives the motor to rotate. The DC motor controls the operation of the vibratory box, which can replace the power of the fuel engine, reduce carbon emissions, and achieve the effects of energy conservation, environmental protection and emission reduction.

[0014] In a preferred embodiment, the present invention may be further configured such that the battery compartment includes:

[0015] The bottom plate is fixed to the base plate;

[0016] The upper panel is positioned above the lower panel;

[0017] The columns are vertically installed between the four corners of the lower panel and the upper panel;

[0018] The battery cells are arranged on the upper end face of the lower panel and the lower end face of the upper panel, and heat dissipation gaps are provided between the upper and lower layers of battery cells and between two adjacent battery cells.

[0019] By adopting the above technical solution and setting up a hollow battery compartment, the cells are prevented from contacting each other, thus preventing impacts or wear caused by vibration and ensuring the lifespan of the cells. At the same time, heat dissipation gaps are reserved between the cells to ensure permeability, which is beneficial for heat dissipation and ensures the stability of the cells' operation.

[0020] In a preferred embodiment, the present invention can be further configured such that: a fan is provided at the tail of the motor, a duct is provided on the fan, a serpentine flow channel is provided through the upper panel and the lower panel, and the duct is connected to the serpentine flow channel.

[0021] By adopting the above technical solution, when the motor is working, it will drive the fan to work. At this time, the fan blows cold air into the air duct and into the serpentine flow channel. Then, through the heat exchange principle, the heat generated by the battery cell is removed, improving the heat dissipation effect of the battery compartment.

[0022] In a preferred embodiment, the present invention may be further configured such that: a flat air outlet is provided between the two columns located at the same end, the air outlet faces the heat dissipation gap, and a connecting pipe communicating with the air outlet is provided on the air duct.

[0023] By adopting the above technical solution, when the battery cell is cooled, the air is blown into the cooling gap through the air outlet, increasing the airflow and achieving all-round cooling of the battery cell, thereby improving the cooling effect of the battery compartment.

[0024] In a preferred embodiment, the present invention can be further configured such that: a hollow rotating shaft is provided on the air outlet, the rotating shaft is rotatably connected to the column and communicates with the air outlet, the rotating shaft is communicated with the connecting pipe, and a drive mechanism for controlling the reciprocating rotation of the rotating shaft is provided on the base plate.

[0025] By adopting the above technical solution and setting up reciprocating oscillating air vents, heat dissipation can be achieved at both the heat dissipation gap and the surface of the battery cell, thus achieving all-round heat dissipation of the battery cell and improving the heat dissipation effect of the battery compartment.

[0026] In a preferred embodiment, the invention can be further configured such that the rotating shafts with opposite positions rotate in opposite directions.

[0027] By adopting the above technical solution, since the rotation direction of the shaft is opposite, the surface of the battery cell can be cooled in an alternating manner when the air outlet swings, ensuring that the battery cell is always in a cooling environment and improving the heat dissipation effect of the battery compartment.

[0028] In a preferred embodiment, the present invention can be further configured such that the driving mechanism includes:

[0029] A rack is vertically slidably connected to the upper panel and the lower panel;

[0030] A gear is disposed on the outer wall of the rotating shaft and meshes with the rack;

[0031] A bracket is mounted on the top plate;

[0032] A crossbar is rotatably connected to the bracket, and its two ends are rotatably connected to the upper end of the rack, respectively.

[0033] A linkage mechanism is used to control the up-and-down movement of the rack.

[0034] By adopting the above technical solution, when the control shaft reciprocates, a linkage mechanism controls the up-and-down movement of one rack. When the rack moves, it drives the other rack to move up and down under the linkage of the crossbar, and the two racks move in opposite directions. Simultaneously, the rack drives the gear to reciprocate, and the gear drives the shaft to oscillate back and forth, thus achieving the reciprocating oscillation control of the air outlet. Therefore, by setting up a cleverly structured and stable drive mechanism, the reciprocating oscillation control of the air outlet is achieved, ensuring the heat dissipation effect of the battery compartment.

[0035] In a preferred embodiment, the present invention can be further configured such that the linkage mechanism includes:

[0036] A pair of synchronous pulleys are located at the tail end of the motor shaft and beside the rack;

[0037] Synchronous belt, wound around a pair of said synchronous belts;

[0038] A protrusion is provided on the outer side of the rack that meshes with the gear;

[0039] A drive block is disposed on the timing belt located beside the rack and is used to drive the protrusion to move upward.

[0040] A counterweight is disposed at the lower end of the rack that meshes with the gear.

[0041] By adopting the above technical solution, when the motor is working, the synchronous pulley and synchronous belt will control the drive block to rotate together. When the drive block contacts the cam, it will drive the cam and rack to move upward. When the drive block disengages from the cam, the weight of the counterweight will drive the rack to move in the opposite direction, thereby realizing the reciprocating motion control of the rack. Therefore, by setting a highly interconnected linkage mechanism, the reciprocating motion control of the rack can be achieved without adding other drive sources.

[0042] In a preferred embodiment, the present invention can be further configured such that shock-absorbing support legs are provided at the four corners of the lower end face of the battery compartment.

[0043] By adopting the above technical solution and setting up shock-absorbing support legs, the battery compartment can be shock-absorbing during the operation of the plate compactor, thus preventing damage to the battery compartment.

[0044] In summary, the present invention has the following beneficial effects:

[0045] 1. By using the lithium battery in the battery compartment to provide power and drive the motor to rotate, and using the DC motor to control the operation of the vibration box, it can replace the power of the fuel engine, reduce carbon emissions, and achieve the effects of energy conservation, environmental protection and energy saving and emission reduction.

[0046] 2. By adopting air cooling and utilizing the principle of heat exchange, the heat generated by the battery cells during operation is removed, thereby improving the heat dissipation effect of the battery compartment;

[0047] 3. By setting up reciprocating oscillating air vents, heat dissipation can be achieved at both the heat dissipation gap and the surface of the battery cell, thus achieving all-round heat dissipation of the battery cell and improving the heat dissipation effect of the battery compartment.

[0053] The present invention will be further described in detail below with reference to the accompanying drawings.

[0054] like Figure 1 As shown, a new energy power plate compactor includes a base plate 1, a seat plate 2, a vibration box 3, a motor 4, a battery compartment 5, and a protective frame 6.

[0055] like Figure 1 As shown, the base plate 1 is flat with both ends curving upwards to contact the ground and compact it. The seat plate 2 is located above the base plate 1 and is used for the installation of other structural components. The four corners of the seat plate 2 are connected to the base plate 1 via vibrators 11 to ensure that the seat plate 2 can reduce its swaying when the base plate 1 is working, thus achieving a vibration damping effect.

[0056] like Figure 1 As shown, the vibration box 3 is mounted on the base plate 1 and is used to provide driving force for the vibration of the base plate 1. The motor 4 is a DC type and is mounted on the base plate 2. The shaft of the motor 4 is connected to the cam inside the vibration box 3 via a belt, which drives the cam inside the vibration box 3 to rotate when the motor 4 is working, and generates a stable vibration force.

[0057] like Figure 1 , Figure 2 As shown, the battery compartment 5 is mounted on the base plate 2 and connected to the motor 4 to provide power to the motor 4. Shock-absorbing support legs 51 are provided at the four corners of the lower end face of the battery compartment 5. Each shock-absorbing support leg 51 consists of rubber shock-absorbing blocks and springs, ensuring that it can dampen the battery compartment 5 during the operation of the plate compactor and prevent damage to the battery compartment 5.

[0058] like Figure 1 As shown, the protective frame 6 is set on the base plate 2 and covers the motor 4 and battery compartment 5 to prevent the motor 4 or battery compartment 5 from being impacted by the outside.

[0059] Therefore, when the plate compactor is working, the lithium battery in the battery compartment 5 provides power and drives the motor 4 to rotate. The DC motor 4 controls the operation of the vibratory box 3 to replace the power of the fuel engine, reduce carbon emissions, and achieve the effects of energy conservation, environmental protection and energy saving and emission reduction.

[0060] like Figure 2 , Figure 3 As shown, the battery compartment 5 includes a lower panel 52, an upper panel 53, a column 54, and a battery cell 55. The lower panel 52 is fixed to the base plate 2, the upper panel 53 is located above the lower panel 52, and the column 54 is vertically located between the four corners of the lower panel 52 and the upper panel 53, so that a hollow installation space is formed between the upper panel 53 and the lower panel 52.

[0061] like Figure 2 , Figure 3 As shown, multiple battery cells 55 are provided and interconnected. The multiple battery cells 55 are arranged on the upper end face of the lower panel 52 and the lower end face of the upper panel 53, and heat dissipation gaps 56 are provided between the upper and lower layers of battery cells 55 and between two adjacent battery cells 55.

[0062] Therefore, during the operation of the plate compactor, the vibration of the battery compartment 5 ensures that the battery cells 55 do not come into contact with each other, preventing impact or wear between the battery cells 55 due to vibration and ensuring the service life of the battery cells 55. At the same time, heat dissipation gaps 56 are reserved between the battery cells 55 to ensure permeability between the battery cells 55, which is conducive to heat dissipation of the battery cells 55 and ensures the working stability of the battery cells 55.

[0063] like Figure 2 , Figure 3 As shown, a fan 41 is installed at the tail of the motor 4, and the shaft of the motor 4 is fixed to the fan blades inside the fan 41. The fan 41 is equipped with an air duct 42 and an air inlet 43. A serpentine flow channel 57 is installed through both the upper panel 53 and the lower panel 52. The air duct 42 is connected to the serpentine flow channel 57. A filter element 44 is installed at the air inlet 43 to filter dust in the cold air.

[0064] Therefore, when the motor 4 is working, it will drive the fan blades in the fan 41 to rotate. At this time, the fan 41 blows the filtered cold air into the air duct 42 and into the serpentine flow channel 57. At this time, through the heat exchange principle, the heat generated by the battery cell 55 is carried away, improving the heat dissipation effect of the battery compartment 5.

[0065] like Figure 2 , Figure 3As shown, a hollow rotating shaft 58 is rotatably connected between two columns 54 located at the same end, and the rotating shafts 58 with opposite positions rotate in opposite directions. A flat air outlet 59 is connected to the rotating shaft 58, and the air outlet 59 faces the heat dissipation gap 56. A connecting pipe 45 connecting the rotating shaft 58 is provided on the air duct 42, and a drive mechanism 7 for controlling the reciprocating rotation of the rotating shaft 58 is provided on the base plate 2.

[0066] Therefore, when the cell 55 is cooled, the cold air is transferred to the air outlet 59. At this time, the air outlet 59 is used to blow the cold air into the heat dissipation gap 56, increasing the flow rate and velocity of the cold air, and realizing heat dissipation on the surface of the cell 55 in all directions, thereby improving the heat dissipation effect of the battery compartment 5.

[0067] Because the rotating shaft 58 rotates in opposite directions, the two air vents 59 first dissipate heat from the upper and lower battery cells 55 respectively, and then blow heat together into the heat dissipation gap 56. This generates strong convection, which is beneficial for heat dissipation of the battery cells 55. Subsequently, the positions of the two air vents 59 are interchanged to dissipate heat from the battery cells 55 on the other layer. This process is repeated, achieving heat dissipation at the heat dissipation gap 56 and also dissipating heat from the surface of the battery cells 55. The staggered heat dissipation ensures that the battery cells 55 are always in a heat-dissipating environment, improving the heat dissipation effect of the battery compartment 5.

[0068] like Figure 3 , Figure 4 As shown, the drive mechanism 7 includes a rack 71, a gear 72, a bracket 73, and a crossbar 74. The rack 71 is vertically slidably connected to the upper panel 53 and the lower panel 52. The gear 72 is disposed on the outer wall of the rotating shaft 58 and meshes with the rack 71. The bracket 73 is disposed on the upper panel 53. The crossbar 74 is rotatably connected to the bracket 73 at its middle position, and its two ends are rotatably connected to the upper end of the rack 71.

[0069] like Figure 3 , Figure 4 As shown, a linkage mechanism 8 is provided on the base to control the up-and-down movement of the rack 71. The linkage mechanism 8 includes a pair of synchronous pulleys 81, a synchronous belt 82, a protrusion 83, a drive block 84, and a counterweight block 85. The pair of synchronous pulleys 81 are respectively located at the tail end of the shaft of the motor 4 and beside the rack 71. The synchronous belt 82 is wound around the pair of synchronous pulleys 81 to drive the pair of synchronous pulleys 81 to rotate synchronously.

[0070] like Figure 3 , Figure 4 As shown, the protrusion 83 is disposed on the outer side of the rack 71 that meshes with the gear 72, and the drive block 84 is disposed on the synchronous pulley 81 located beside the rack 71 and is used to drive the protrusion 83 to move upward. The counterweight block 85 is disposed at the lower end of the rack 71 that meshes with the gear 72 and is used to apply a downward force to the rack 71.

[0071] When the air outlet 59 reciprocates, the motor 4 is in operation. At this time, with the cooperation of the synchronous pulley 81 and the synchronous belt 82, the shaft of the motor 4 will control the drive block 84 to rotate together. When the drive block 84 abuts against the protrusion 83, it will drive the protrusion 83 and one of the racks 71 to move upward.

[0072] At this time, under the linkage of the crossbar 74, another rack 71 is driven to move up and down, and the two racks 71 move in opposite directions. At the same time, the rack 71 drives the gear 72 to rotate back and forth, and the gear 72 drives the rotating shaft 58 to swing back and forth, thereby realizing the reciprocating swing control of the air outlet 59.

[0073] When the drive block 84 disengages from the protrusion 83, under the gravity of the counterweight block 85, it will drive the rack 71 to move in the opposite direction, repeating in sequence to realize the reciprocating motion control of the rack 71, thereby indirectly realizing the reciprocating swing control of the air outlet 59. At the same time, no other drive source needs to be added during this process; only the operation of the motor 4 itself is required, thus achieving the effect of energy saving and emission reduction.

[0074] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
