The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0049] Combination Figure 1 According to the transfer equipment 200 of the embodiment of the present invention, the transfer equipment 200 includes a hydraulic system 100, a box body 210, a flip cover part 220 and a locking part 230. The flip cover part 220 is flippably connected to the box body 210; the locking part 230 is used to lock and unlock the flip cover part 220; the hydraulic system 100 includes: a lifting cylinder 10, a locking cylinder 20, an oil source assembly and a reversing control assembly 40.

[0050] Among them, the lifting cylinder 10 is connected to the flap part 220, and the lifting cylinder 10 is used to drive the flap part 220 to open or close; the locking cylinder 20 is connected to the locking part 230, and the locking cylinder 20 is used to drive the locking part 230 to lock the flap part 220 or unlock the flap part 220. Specifically, when storing garbage, the locking cylinder 20 drives the locking part 230 to lock the flap part 220, and the flap part 220 and the box body 210 are in a locked state. The flap part 220 and the interior of the box body 210 form a storage cavity, and garbage can be stored in the storage cavity to avoid the flap part 220 opening due to the expansion of the garbage when storing garbage with a large expansion coefficient; when unloading the garbage, the locking cylinder 20 drives the locking part 230 to release the lock of the flap part 220, and the lifting cylinder 10 drives the flap part 220 to rotate upward and open relative to the box body 210, thereby destroying the equilibrium state formed by the garbage in the storage cavity, thereby making it easier for the garbage to be poured out from the first opening 221.

[0051] The lifting cylinder 10 has a first chamber 11 and a second chamber 12. For example, the lifting cylinder 10 includes a first piston, a first piston rod and a first cylinder barrel. The first piston divides the first cylinder barrel into the first chamber 11 and the second chamber 12. The first piston rod can be inserted into the first chamber 11, so the first chamber 11 can be set as a first rod chamber, and the second chamber 12 can be set as a first rodless chamber. When the first chamber 11 is filled with oil, the first piston rod retracts toward the first cylinder barrel, and the first piston rod drives the flap part 220 to close; when the second chamber 12 is filled with oil, the first piston rod extends out of the first cylinder barrel, and the first piston rod drives the flap part 220 to open.

[0052] The locking oil cylinder 20 has a third chamber 21 and a fourth chamber 22. For example, the locking oil cylinder 20 includes a second piston, a second piston rod and a second cylinder barrel.

[0054] According to the transfer equipment 200 of the embodiment of the present invention, the reversing control component 40 controls the sequential actions of the lifting cylinder 10 and the locking cylinder 20, avoiding multiple adjustments to the pressure of the reversing control component 40, improving the reliability of the operation of the transfer equipment 200, and reducing the operating costs.

[0055] For example, the oil source assembly may include an oil tank, and the first interface 31 and the second interface 32 are respectively connected to the oil tank.

The second piston rod extends out of the second cylinder barrel, and the locking cylinder 20 performs a locking action and drives the locking part 230 to lock the flip cover part 220. The flip cover part 220 and the box body 210 are in a locked state, and garbage can be stored in the storage chamber.

[0056] like Figure 4 and Fig.15 As shown, when the second interface 32 is the pump oil port, the first interface 31 is the return oil port, and the reversing control assembly 40 is in the first state, the second chamber 12 is filled with oil, and the hydraulic oil in the first chamber 11 flows back to the oil tank through the first interface 31, the first piston rod extends out of the first cylinder, the lifting cylinder 10 performs a lifting action and drives the flip cover 220 to open, and the garbage can be dumped from the first opening 221 to achieve the unloading of the garbage; Figure 6 and Fig.18 As shown, when the reversing control assembly 40 is in the second state, oil enters the third chamber 21, and the hydraulic oil in the fourth chamber 22 flows back to the oil tank through the first interface 31, the second piston rod retracts to the second cylinder barrel, and the locking cylinder 20 performs an unlocking action and drives the locking part 230 to release the lock on the flip cover part 220.

[0057] Of course, the above description is only a description of some specific implementation methods of the present invention based on the drawings, and is not intended to limit the protection scope of the present invention.

[0058] Optionally, the lifting cylinder 10 includes a first piston rod and a first cylinder barrel, the first cylinder barrel can be connected to the box body 210, and the first piston rod can be connected to the flip cover part 220. When the first piston rod extends out of the first cylinder barrel, the first piston rod drives the flip cover part 220 to open; when the first piston rod retracts into the first cylinder barrel, the first piston rod drives the flip cover part 220 to close; the lifting cylinder 10 can be provided with two, and the two lifting cylinders 10 are arranged opposite to each other in the left and right directions to ensure that the flip cover part 220 can be smoothly rotated from the first working position to the second working position to avoid the flip cover part 220 from accidentally falling.

The second cylinder barrel may be provided at the rear end of the box body 210, and the two second piston rods are respectively connected to the two locking parts 230, and when the second piston rod extends out of the second cylinder barrel, the second piston rod drives the locking part 230 to lock; when the second piston rod retracts into the second cylinder barrel, the second piston rod drives the locking part 230 to unlock.

[0060] Optionally, the first interface 31 and the second interface 32 can be quick-change connectors, which have good corrosion resistance and wear resistance, ensure the stability of hydraulic oil supply and reflux, and are easy to disassemble and replace, which can greatly shorten replacement time and cost, and reduce equipment downtime and production losses.

[0061] Optionally, a first one-way throttle valve 71 may be provided between the first interface 31 and the reversing control assembly 40, and a second one-way throttle valve 72 may be provided between the second interface 32 and the reversing control assembly 40, for adjusting the flow of the hydraulic oil. Fig. 9 as shown; or, in combination Figure 1 A first flow distribution valve may be provided between the first interface 31 and the reversing control assembly 40, and a second flow distribution valve may be provided between the second interface 32 and the reversing control assembly 40, so as to reduce the high temperature and noise generated by overflow.

[0062] In some embodiments, the reversing control component 40 includes a first reversing unit 41 and a second reversing unit 42. The first reversing unit 41 is used to control the first interface 31 to switchably connect to one of the first chamber 11 and the fourth chamber 22. The second reversing unit 42 is used to control the second interface 32 to switchably connect to one of the second chamber 12 and the third chamber 21. The first reversing unit 41 and the second reversing unit 42 switch between the first state and the second state, thereby realizing the lifting or lowering action of the lifting cylinder 10, or the unlocking and locking action of the locking cylinder 20.

[0063] For example, the first reversing unit 41 has a first valve position, a second valve position, and a third valve position, and can be switched among the first valve position, the second valve position, and the third valve position.

When the first interface 31 is the pump oil port and the second interface 32 is the return oil port, the first chamber 11 is filled with oil, and the hydraulic oil in the second chamber 12 is refluxed. The first piston rod retracts toward the first cylinder barrel, and the lifting cylinder 10 performs a lowering action.

[0069] For example, the first cylinder of the lifting cylinder 10 is divided into a first chamber 11 and a second chamber 12 by the first piston, wherein the second chamber 12 can be set as a first rodless chamber. Figure 4 or Fig.11 The second interface 32 is a pump oil port, and the hydraulic oil flows into the second chamber 12 from the second interface 32.

[0070] In addition, the second cylinder barrel of the locking oil cylinder 20 is divided into a third chamber 21 and a fourth chamber 22 by the second piston, wherein the third chamber 21 can be set as a second rodless chamber. Figure 6 or Fig.13 The second interface 32 is the pump oil port, and the hydraulic oil enters the third chamber 21 through the second interface 32. At this time, the second piston rod gradually retracts toward the second cylinder barrel, and the locking cylinder 20 performs the unlocking action; combined with Figure 5 or Fig.12The second interface 32 is an oil return port, and the hydraulic oil flows out of the third chamber 21 and flows back to the oil tank through the second interface 32. At this time, the second piston rod gradually extends out of the second cylinder barrel, and the locking cylinder 20 performs a locking action.

[0071] Optionally, the first reversing unit 41 and the second reversing unit 42 can be reversing valves. Compared with the use of sequential valves, the hydraulic system 100 uses two reversing valves to avoid multiple adjustments to the pressure of the reversing valves and prevent the valve core in the reversing valve from getting stuck, thereby ensuring the reliability of the hydraulic system 100 and reducing operating costs; the first reversing unit 41 can be a first three-position three-way reversing valve, and the second reversing unit 42 can be a second three-position three-way reversing valve. The three-position three-way reversing valve can have three valve positions and three valve ports, which meet the operating requirements of the first reversing unit 41 and the second reversing unit 42. The three-position three-way reversing valve can switch between the three valve positions to achieve flexible control of the flow direction of the fluid, and can meet different fluid control requirements. The three-position three-way reversing valve has a simple structure, stable operation, and a long service life. It does not need to be replaced frequently, thereby reducing operating costs.

[0072] Combination Figures 3 to 6 or Figures 10 to 13 In some embodiments, the first switching unit 41 and the second switching unit 42 are linked to control the first switching unit 41 and the second switching unit 42 to switch simultaneously.

[0073] For example, in the first state, the first valve port A1 is connected to the second valve port B1, and the fourth valve port A2 is connected to the fifth valve port B2. When the first interface 31 is connected to the first chamber 11 to form an oil inlet, and the second interface 32 is connected to the second chamber 12 to form an oil return, the first piston rod retracts toward the first cylinder barrel, thereby realizing the lowering action of the lifting cylinder 10; when the first interface 31 is connected to the first chamber 11 to form an oil return, and the second interface 32 is connected to the second chamber 12 to form an oil inlet, the first piston rod extends out of the first cylinder barrel, thereby realizing the lifting action of the lifting cylinder 10, avoiding the lack of an oil inlet or oil return in the lifting cylinder 10, which causes the lifting cylinder 10 to be unable to perform lifting and lowering actions.

[0074] In addition, in the second state, the first valve port A1 is connected with the third valve port C1, and the fourth valve port A2 is connected with the sixth valve port C2. When the first interface 31 and the fourth chamber 22 are connected to form an oil inlet circuit, and the second interface 32 and the third chamber 21 are connected to form an oil return circuit, the second piston rod extends out of the second cylinder barrel, thereby realizing the locking action of the locking cylinder 20; when the first interface 31 and the fourth chamber 22 are connected to form an oil return circuit, and the second interface 32 and the third chamber 21 are connected to form an oil inlet circuit, the second piston rod retracts toward the second cylinder barrel, thereby realizing the unlocking action of the locking cylinder 20, avoiding the lack of an oil inlet circuit or an oil return circuit in the locking cylinder 20, which causes the locking cylinder 20 to be unable to perform locking and unlocking actions.

[0075] Optionally, the reversing control component 40 can be set as a manual reversing valve, and a handle can be provided on the manual reversing valve, through which the direction of the hydraulic oil can be easily switched and controlled. The manual reversing valve has a compact structure and a high degree of standardization, which ensures the stability of the hydraulic system 100. At the same time, the manual reversing valve has a long service life and a relatively low price, which reduces the production cost of the hydraulic system 100.

[0076] Combination Figures 3 to 6 or Figures 10 to 13 In some embodiments, a two-way balancing valve 50 is provided between the reversing control component 40 and the lifting cylinder 10, a first oil circuit is provided between the reversing control component 40 and the first chamber 11, and a second oil circuit is provided between the reversing control component 40 and the second chamber 12. The two-way balancing valve 50 is respectively connected to the first oil circuit and the second oil circuit, and is used to maintain the pressure of the first oil circuit and the pressure of the second oil circuit within a set range to avoid excessive flow rate of the hydraulic oil in the first oil circuit or the second oil circuit.

[0077] For example, the two-way balancing valve 50 has a first balancing valve and a second balancing valve, the first balancing valve is arranged in the first oil circuit, and the second balancing valve is arranged in the second oil circuit. The first balancing valve includes a first overflow valve and a first non-return valve, and the second balancing valve includes a second overflow valve and a second non-return valve. The control circuit of the first overflow valve is connected to the second oil circuit, and the control circuit of the second overflow valve is connected to the first oil circuit. When the pressure of the first oil circuit and the pressure of the second oil circuit exceed the set range, the two-way balancing valve 50 can automatically adjust the opening degree of the first overflow valve and the second overflow valve to ensure the stability of the hydraulic oil flow in the first oil circuit and the second oil circuit.

[0078] Among them, Figure 3 or Fig.10 As shown, the first oil circuit is the oil inlet circuit, and the second oil circuit is the oil return circuit. When the pressure of the control circuit of the second relief valve is greater than the elastic force in the second relief valve, the second relief valve opens, and the hydraulic oil in the second chamber 12 flows back through the second relief valve; when the pressure of the control circuit of the first relief valve is greater than the elastic force in the first relief valve, the first relief valve opens to reduce the pressure of the first oil circuit until the pressure of the control circuit of the first relief valve is less than the elastic force in the first balance valve, and the first relief valve closes, so that the pressure of the first oil circuit and the pressure of the second oil circuit are readjusted to the set range, thereby maintaining the stability of the flow. When the second oil circuit is the oil inlet circuit and the first oil circuit is the oil return circuit, the working principle of the two-way balance valve 50 is similar to the above principle, and no further description is given here.

[0079] Furthermore, the reversing control assembly 40 is connected to the lifting cylinder 10 and the locking cylinder 20 through a pipeline. The two-way balance valve 50 is arranged between the reversing control assembly 40 and the lifting cylinder 10, and the two-way balance valve 50 is set with a pressure range, which can prevent the flow rate of the hydraulic oil from being too large, and at the same time avoid overspeed when the flap part 220 descends, and the flap part 220 suddenly falls when the pipeline is damaged. In addition, when the locking part 230 locks the box body 210 and the flap part 220, a storage cavity is formed inside the box body 210 and the flap part 220, and garbage with a large expansion coefficient is stored. The two-way balance valve 50 can effectively prevent the flap part 220 from suddenly accelerating and opening due to the rebound force of the garbage with a large expansion coefficient when the locking cylinder 20 unlocks the locking part 230.

[0080] Combination Figure 5 and Figure 6 or Fig.12 and Fig.13 In some embodiments, a one-way hydraulic lock 60 is provided between the reversing control assembly 40 and the locking cylinder 20, a third oil circuit is provided between the reversing control assembly 40 and the third chamber 21, a fourth oil circuit is provided between the reversing control assembly 40 and the fourth chamber 22, and the one-way hydraulic lock 60 includes a two-way passage and a one-way passage, the two-way passage is connected to the third oil circuit, the one-way passage is connected to the fourth oil circuit, and the one-way oil circuit is configured to be controllably one-way from the reversing control assembly 40 to the fourth chamber 22. The control oil circuit of the one-way hydraulic lock 60 is connected to the third oil circuit to control the one-way hydraulic lock 60 to achieve reverse conduction.

[0081] Specifically, when the fourth oil circuit is the oil inlet circuit and the third oil circuit is the oil return circuit, the hydraulic oil can enter the fourth chamber 22 through the fourth oil circuit, and the one-way hydraulic lock 60 is forward-conducted at this time; when the locking cylinder 20 remains in a locked state, the one-way hydraulic lock 60 is locked to prevent the hydraulic oil in the fourth chamber 22 from flowing back in the opposite direction, thereby ensuring that the locking cylinder 20 always remains in a locked state; when the third oil circuit is the oil inlet circuit and the fourth oil circuit is the oil return circuit, the hydraulic oil of the third oil circuit is input into the control oil circuit, and the hydraulic oil pushes open the one-way hydraulic lock 60, thereby realizing the reverse conduction of the one-way hydraulic lock 60 and allowing the hydraulic oil in the fourth chamber 22 to flow back.

[0082] Furthermore, when the locking cylinder 20 remains in the locked state, the hydraulic oil in the fourth chamber 22 cannot flow back, ensuring that the locking cylinder 20 always remains in the locked state, so that the flap part 220 can be reliably locked, thereby avoiding garbage leakage caused by accidental opening of the flap part 220.

[0083] Combination Fig. 9In some embodiments, a first one-way throttle valve 71 is provided between the first interface 31 and the reversing control assembly 40. The throttle valve of the first one-way throttle valve 71 can adjust the flow rate of the hydraulic oil, and the one-way valve of the first one-way throttle valve 71 is configured to be one-way from the reversing control assembly to the first interface. The flow rate of the hydraulic oil supplied by the oil source assembly is relatively large. When the first interface 31 is a pump oil port, the first one-way throttle valve 71 can adjust the flow rate of the hydraulic oil, and the excess hydraulic oil overflows from the first overflow valve (not shown in the figure) back to the oil tank, thereby ensuring that the flow rate of the hydraulic oil input to the reversing control assembly 40 is stable, and preventing the lifting cylinder 10 from lowering too fast.

[0084] Optionally, the first one-way throttle valve 71 can be provided with a first damping hole. When the flow rate of the hydraulic oil input by the first interface 31 changes, the hydraulic oil generates resistance through the first damping hole, slowing down the flow rate of the hydraulic oil, making the flow rate of the hydraulic oil output after passing through the first one-way throttle valve 71 more stable, and reducing the vibration and hydraulic shock of the first one-way throttle valve 71, thereby improving the stability and reliability of the hydraulic oil output from the first interface 31 and avoiding damage to components in the hydraulic system 100 due to excessive flow rate of the hydraulic oil.

[0085] In some embodiments, a second one-way throttle valve 72 is provided between the second interface 32 and the reversing control assembly 40. The throttle valve of the second one-way throttle valve 72 can adjust the flow rate of the hydraulic oil, and the one-way valve of the second one-way throttle valve 72 is configured to be one-way from the reversing control assembly to the second interface. The flow rate of the hydraulic oil supplied by the oil source assembly is relatively large. When the second interface 32 is a pump oil port, the second one-way throttle valve 72 can adjust the flow rate of the hydraulic oil, and the excess hydraulic oil overflows from the second overflow valve (not shown in the figure) back to the oil tank, thereby ensuring that the flow rate of the hydraulic oil input to the reversing control assembly 40 is stable, and preventing the lifting cylinder 10 from performing the lifting action too fast.

[0086] Optionally, the second one-way throttle valve 72 can be provided with a second damping hole. When the flow rate of the hydraulic oil input by the second interface 32 changes, the hydraulic oil generates resistance through the second damping hole, slowing down the flow rate of the hydraulic oil, making the flow rate of the hydraulic oil output after passing through the second one-way throttle valve 72 more stable, and reducing the vibration and hydraulic shock of the second one-way throttle valve 72, thereby improving the stability and reliability of the hydraulic oil output from the second interface 32 and avoiding damage to components in the hydraulic system 100 due to excessive flow rate of the hydraulic oil.

[0087] Combination Figures 1 to 8In some embodiments, a first flow distribution valve is provided between the first interface 31 and the reversing control component 40. The first flow distribution valve is configured to control the flow rate of the first interface 31 pumped to the reversing control component 40. The first flow distribution valve controls the flow rate of the hydraulic oil and inputs the required flow rate into the reversing control component 40. The excess hydraulic oil flows back to the oil tank from the first flow distribution valve, reducing the high noise and high temperature caused by overflow loss, being more energy-efficient and efficient, preventing the hydraulic oil flow from being too large and causing the lifting cylinder 10 to lower too fast, and preventing the hydraulic oil pressure from being too high and damaging the components in the hydraulic system 100.

[0088] Combination Figure 2 and Figure 7 In some embodiments, the first flow distribution valve includes: a first throttle valve 81 and a first pressure compensating valve 82. The first end of the first throttle valve 81 is connected to the first interface 31, which is used to adjust the hydraulic oil flow output by the first interface 31; the first pressure compensating valve 82 includes a first port, a second port b1, a third port c1 and a fourth port d1. The first port is connected to the second end of the first throttle valve 81, the second port b1 is connected to the reversing control component 40, the third port c1 is connected to the first end of the first throttle valve 81, and the fourth port d1 is used for returning oil. The first pressure compensating valve 82 has a first position and a second position. In the first position, the first port is connected to the second port b1, and the third port c1 is disconnected from the fourth port d1. In the second position, the first port is disconnected from the second port b1, and the third port c1 is connected to the fourth port d1.

[0089] Specifically, the first throttle valve 81 provides the hydraulic oil flow required by the reversing control component 40. When the first pressure compensation valve 82 is in the first position, the second end of the first throttle valve 81 is connected to the reversing control component 40, and the hydraulic oil can be input into the reversing control component 40 from the first interface 31 through the first throttle valve 81 and the first pressure compensation valve 82, or the hydraulic oil flows back to the oil tank from the reversing control component 40 through the first pressure compensation valve 82, the first throttle valve 81 and the first interface 31. When the first throttle valve 81 is in the second position, the first end of the first throttle valve 81 is connected to the fourth port d1, and the fourth port d1 is connected to the second interface 32, and the excess hydraulic oil flows back to the oil tank from the first pressure compensation valve 82 and the second interface 32.

[0090] Among them, the first pressure compensating valve 82 has a first hydraulic control end, a second hydraulic control end and a first elastic member 821. The first hydraulic control end is connected to the first end of the first throttle valve 81, and the second hydraulic control end is connected to the second end of the first throttle valve 81. The first elastic member 821 is arranged at the second hydraulic control end and is used to drive the first pressure compensating valve 82 to the first position. When the pressure at the first hydraulic control end is greater than the sum of the pressure at the second hydraulic control end and the elastic force of the first elastic member 821, the first pressure compensating valve 82 switches from the first position to the second position; when the pressure at the first hydraulic control end is less than the pressure at the second hydraulic control end and the elastic force of the first elastic member 821, the first pressure compensating valve 82 switches from the second position to the first position.

[0091] Specifically, the pressure at the first hydraulic control end is equal to the pressure at the first end of the first throttle valve 81, the pressure at the second hydraulic control end is equal to the pressure at the second end of the first throttle valve 81, the first elastic member 821 has an elastic force that moves the first pressure compensation valve 82 toward the first position, the pressure direction at the second hydraulic control end is the same as the elastic force direction of the first elastic member 821, and the pressure direction at the first hydraulic control end is opposite to the elastic force direction of the first elastic member 821. When the pressure at the first hydraulic control end is less than the sum of the pressure at the second hydraulic control end and the elastic force of the first elastic member 821, the first pressure compensation valve 82 is located at the first position, the second end of the first throttle valve 81 is connected to the reversing control assembly 40, and the hydraulic oil can flow into the reversing control assembly 40 through the first throttle valve 81 and the first pressure compensation valve 82, or flow back to the oil tank from the reversing control assembly 40 through the first pressure compensation valve 82 and the first throttle valve 81.

[0092] When the pressure at the first hydraulic control end is greater than the sum of the pressure at the second hydraulic control end and the elastic force of the first elastic member 821, the first elastic member 821 is compressed, the hydraulic oil pushes the first pressure compensation valve 82 to switch from the first position to the second position, the third port c1 is connected to the fourth port d1, the first end of the first throttle valve 81 is connected to the second interface 32, and the excess hydraulic oil flows back to the oil tank after passing through the first pressure compensation valve 82 and the second interface 32, so as to avoid the working pressure of the first pressure compensation valve 82 being too high and heating, thereby reducing the overflow loss of the hydraulic oil. When the excess hydraulic oil flows back to the oil tank, the first hydraulic control end is depressurized, the sum of the pressure at the second hydraulic control end and the elastic force of the first elastic member 821 is greater than the pressure at the first hydraulic control end again, the first elastic member 821 releases the elastic force and drives the first pressure compensation valve 82 to switch from the second position to the first position, and the second end of the first throttle valve 81 is connected to the reversing control assembly 40, so that the hydraulic oil can flow into the reversing control assembly 40 through the first throttle valve 81.

[0093] Optionally, the first throttle valve 81 can be an adjustable flow valve, which can adjust the flow of hydraulic oil manually or automatically to provide the required flow of hydraulic oil, avoid frequent replacement of flow control elements, and the adjustable flow valve has a simple structure and is easy to install and maintain. The first throttle valve 81 can also be a one-way throttle valve, which can include a first one-way valve. When the hydraulic oil is input into the first pressure compensation valve 82 from the first interface 31, the first one-way valve is cut off, which is used to limit the hydraulic oil to flow in one direction when the first interface 31 is a pump oil port; when the hydraulic oil flows from the first pressure compensation valve 82 to the first interface 31, the first one-way valve is turned on, and the hydraulic oil can flow back to the first interface 31 through the first one-way valve.

[0094] Optionally, when the first pressure compensation valve 82 is in the second position, a second one-way valve may be provided in the oil return circuit of the fourth port d1, and the second one-way valve is configured to provide one-way conduction from the fourth port d1 to the second interface 32, thereby preventing the second interface 32 from starting to take in oil due to a malfunction, causing oil circuit disturbances in the hydraulic system 100, and ensuring the stability of the hydraulic system 100.

[0095] Optionally, the first elastic member 821 may be a spring, which has good elasticity and resilience, can withstand a certain pressure and deformation, is not easily deformed and fatigued, and has a relatively long service life; when the first pressure compensating valve 82 is in the first position, the spring may provide sufficient elastic force to keep the first pressure compensating valve 82 in the first position; when the first pressure compensating valve 82 switches between the first position and the second position, the spring may make the first pressure compensating valve 82 respond faster and enable the first pressure compensating valve 82 to switch positions quickly.

[0096] Combination Figures 1 to 8 In some embodiments, a second flow distribution valve is provided between the second interface 32 and the reversing control component 40. The second flow distribution valve is configured to control the flow rate of the second interface 32 pumped to the reversing control component 40. The second flow distribution valve controls the flow rate of the hydraulic oil and inputs the required flow rate to the reversing control component 40. The excess hydraulic oil flows back to the oil tank from the second flow distribution valve, reducing the high noise and high temperature caused by overflow loss, preventing the lifting cylinder 10 from lifting too fast due to excessive hydraulic oil flow, and preventing excessive hydraulic oil pressure from damaging components in the hydraulic system 100.

The second pressure compensating valve 92 has a third position and a fourth position. In the third position, the fifth port a2 is connected to the sixth port b2, and the seventh port c2 is disconnected from the eighth port d2. In the fourth position, the fifth port a2 is disconnected from the sixth port b2, and the seventh port c2 is connected to the eighth port d2.

[0098] Specifically, the second throttle valve 91 provides the hydraulic oil flow required by the reversing control component 40. When the second pressure compensation valve 92 is in the third position, the second end of the second throttle valve 91 is connected to the reversing control component 40, and the hydraulic oil can be input into the reversing control component 40 from the second interface 32 through the second throttle valve 91, or the hydraulic oil flows back to the oil tank from the reversing control component 40 through the second pressure compensation valve 92, the second throttle valve 91 and the second interface 32.

[0099] Among them, the second pressure-compensating valve 92 has a third hydraulic control end, a fourth hydraulic control end and a second elastic member 921. The third hydraulic control end is connected to the first end of the second throttle valve 91, and the fourth hydraulic control end is connected to the second end of the second throttle valve 91. The second elastic member 921 is arranged at the fourth hydraulic control end and is used to drive the second pressure-compensating valve 92 to the third position. When the pressure at the third hydraulic control end is greater than the sum of the pressure at the fourth hydraulic control end and the elastic force of the second elastic member 921, the second pressure-compensating valve 92 switches from the third position to the fourth position; when the pressure at the third hydraulic control end is less than the pressure at the fourth hydraulic control end and the sum of the elastic force of the second elastic member 921, the second pressure-compensating valve 92 switches from the fourth position to the third position.

When the pressure at the third hydraulic control end is less than the sum of the pressure at the fourth hydraulic control end and the elastic force of the second elastic member 921, the second pressure compensation valve 92 is located at the third position, the second end of the second throttle valve 91 is connected to the reversing control assembly 40, and the hydraulic oil can flow into the reversing control assembly 40 through the second throttle valve 91 and the second pressure compensation valve 92, or flow back to the oil tank from the reversing control assembly 40 through the second pressure compensation valve 92 and the second throttle valve 91.

[0101] When the pressure of the third hydraulic control end is greater than the sum of the pressure of the fourth hydraulic control end and the elastic force of the second elastic member 921, the second elastic member 921 is compressed, the hydraulic oil pushes the second pressure compensation valve 92 to switch from the third position to the fourth position, the seventh port c2 is connected to the eighth port d2, the first end of the second throttle valve 91 is connected to the first interface 31, and the excess hydraulic oil flows back to the oil tank after passing through the second pressure compensation valve 92 and the first interface 31, so as to avoid the working pressure of the second pressure compensation valve 92 being too high and heating, thereby reducing the overflow loss of the hydraulic oil. When the excess hydraulic oil flows back to the oil tank, the third hydraulic control end is depressurized, the sum of the pressure of the fourth hydraulic control end and the elastic force of the second elastic member 921 is greater than the pressure of the third hydraulic control end again, the second elastic member 921 releases the elastic force and drives the second pressure compensation valve 92 to switch from the fourth position to the third position, and the second end of the second throttle valve 91 is connected to the reversing control component 40, so that the hydraulic oil can flow into the reversing control component 40 through the second throttle valve 91.

The second throttle valve 91 can also be a one-way throttle valve, which can include a third one-way valve. When the hydraulic oil is input into the second pressure compensation valve 92 from the second interface 32, the third one-way valve is cut off to limit the hydraulic oil to flow in one direction when the second interface 32 outputs the hydraulic oil; when the hydraulic oil flows from the second pressure compensation valve 92 to the second interface 32, the third one-way valve is turned on, and the hydraulic oil can flow back to the second interface 32 through the third one-way valve.

In the first working position, the bottom of the flip cover portion 220 is connected to the box body 210, and the flip cover portion 220 and the box body 210 form a storage cavity for storing garbage and materials; in the second working position, the bottom of the flip cover portion 220 is separated from the box body 210, destroying the equilibrium state of garbage with a large expansion coefficient in the storage cavity, thereby facilitating the full unloading of the garbage.

[0111] For example, the locking portion 230 is movably arranged on the box body 210, and the flip cover portion 220 is provided with a positioning portion 222. In the first working position, the locking cylinder 20 drives the locking portion 230 to move between the positions of the locking positioning portion 222 and the unlocking positioning portion 222. When the locking cylinder 20 drives the locking portion 230 to lock the positioning portion 222, the flip cover portion 220 and the box body 210 are in a locked state, and the flip cover portion 220 cannot rotate upward relative to the box body 210. The flip cover portion 220 and the box body 210 form a The storage cavity is used to store garbage and materials; when the locking cylinder 20 drives the locking part 230 to release the lock of the positioning part 222, the flip cover part 220 and the box body 210 are in an unlocked state. Driven by the lifting cylinder 10, the flip cover part 220 can rotate upward around the front of the box body 210, and the flip cover part 220 and the box body 210 are separated and rotated from the first working position to the second working position, thereby destroying the equilibrium state formed by the garbage with a large expansion coefficient in the storage cavity, making it easier to unload the garbage to the outside.

[0112] Optionally, combined Figures 16 to 18The locking part 230 and the positioning part 222 may be provided with two, respectively. The two locking parts 230 may be provided at the bottom of the box body 210 and distributed along the left and right directions. When the flip cover part 220 is in the first working position, the positioning part 222 and the locking part 230 may be opposite to each other along the left and right directions, so as to avoid occupying the internal space of the box body 210 and increase the storage space of the garbage. The locking part 230 may include a first locking tongue and a second locking tongue, and the positioning part 222 may include a first positioning hole and a second positioning hole. When the locking part 230 locks the positioning part 222, the locking oil cylinder 20 drives the locking part 230 to lock, the first locking tongue extends into the first positioning hole, and the second locking tongue extends into the second positioning hole, so as to restrict the flip cover part 220 from rotating upward; when the locking part 230 unlocks the positioning part 222, the locking oil cylinder 20 drives the locking part 230 to unlock, the first locking tongue exits the first positioning hole, and the second locking tongue exits the second positioning hole, so as to release the locking of the flip cover part 220.

[0113] The specification of the present invention and its drawings mainly illustrate the movement of the locking portion 230 between the positions of the locking positioning portion 222 and the unlocking positioning portion 222 as an example. This does not limit the scope of protection of the present invention. For example, the locking portion 230 can hook the positioning portion 222 to lock it, and the locking portion 230 can adopt other locking and unlocking methods for the positioning portion 222.

Figure 2 shown.
