[0026] Figure 1 FIG. 2 shows a schematic diagram of an automobile dismantling machine based on an excavator according to an embodiment of the present disclosure. Figure 1 As shown, the automobile dismantling machine may include an excavator base 1, a control system (not shown), a shearing mechanism 3 and a frame pressing mechanism 4. The excavator base 1 may include a structure that a conventional excavator usually has (except for a bucket), that is, it may include a frame 11, and a cab 12, a traveling mechanism 13 and a lifting arm 14, etc., which are respectively mounted on the frame 11. The excavator base 1 may also include a basic hydraulic system, which may include hydraulic circuits (or hydraulic subsystems) for controlling multiple actuators, such as a traveling hydraulic circuit for controlling the traveling mechanism 13, a lifting arm hydraulic circuit for controlling the rise and fall of the lifting arm 14, and a slewing hydraulic circuit for controlling the slewing of the cab 12. Each hydraulic circuit may include one or more of a hydraulic pipeline leading to a related actuator, a hydraulic pump for generating and transmitting a pressurized fluid, a switch valve for allowing or cutting off a hydraulic fluid flow, a switching valve for converting the direction of a hydraulic fluid flow, a proportional control valve for adjusting the flow of a hydraulic fluid flow, a hydraulic cylinder and / or a hydraulic motor for driving an actuator, and the like.

[0027] The shearing mechanism 3 is installed at the free end of the lifting arm 14, that is, the position where the bucket was originally installed, and is associated with the shearing hydraulic circuit so that it can be controlled by the control system to achieve the shearing and dismantling of the scrapped car body. To this end, the shearing mechanism 3 can be as follows Figure 1As shown in FIG. 1 , the vehicle body includes two shear jaws 34 , which can be controlled by the control system via a shear hydraulic circuit to be opened and closed so as to clamp and cut the vehicle body material and release the sheared material.

[0028] The pressing frame mechanism 4 is installed at the front end of the vehicle frame 11 and is located in front of the cab 12 and below the lifting arm 14, so as to cooperate with the shearing mechanism 3. The pressing frame mechanism 4 can include two clamping jaws 41, which can be synchronously controlled by the control system through the pressing frame hydraulic circuit to approach or move away from each other, thereby clamping or releasing the vehicle body to be sheared. The two clamping jaws 41 can also be controlled to rise or fall, so as to cooperate with the shearing mechanism 3.

[0029] It can be understood that the shearing hydraulic circuit and the frame pressing hydraulic circuit can be connected to the original basic hydraulic system of the excavator base 1 in an openable and closable manner, and they can include the existing parts of the basic hydraulic system, and can also include parts specially set up to control the shearing mechanism 3 or the frame pressing mechanism 4. For example, the shearing hydraulic circuit can include at least part of the hydraulic circuit originally used to control the bucket in the basic hydraulic system, and the frame pressing hydraulic circuit can include part of the hydraulic circuit originally used to control the walking mechanism 13 in the basic hydraulic system, as described in detail below.

[0030] Advantageously, the shear hydraulic circuit may include a merging solenoid valve 42 connected to the basic hydraulic system, which may be arranged in a hydraulic pipeline for connecting the hydraulic fluid input end of the shear hydraulic circuit with the hydraulic fluid output end of other hydraulic circuits of the basic hydraulic system, especially the hydraulic circuit of an idle mechanism that does not need to be operated when performing the shearing operation. Figure 3 As shown, the merging solenoid valve 42 may be a switch type solenoid valve, and may be connected to the handle switch (hereinafter referred to as "first button 51") signal through a relay 45, for example. In this way, the operator may open the merging solenoid valve 42 at any time through the handle switch, so as to introduce the pressurized hydraulic fluid in the hydraulic circuit (such as the swing hydraulic circuit, etc.) of the idle mechanism (such as the swing mechanism, etc.) that does not need to be operated when performing the automobile disassembly operation into the shear hydraulic circuit, so that it is supplied to the shear mechanism 3 together with the original hydraulic fluid in the shear hydraulic circuit, thereby increasing the flow rate of the hydraulic fluid in the shear hydraulic circuit, thereby accelerating the shearing speed and improving the working efficiency.

[0031] In a preferred embodiment of the present disclosure, the frame pressing hydraulic circuit may include a controllable switching solenoid valve 43, which may be connected to the travel hydraulic circuit, so as to introduce the pressurized hydraulic fluid flow in the travel hydraulic circuit into the frame pressing hydraulic circuit, especially when the switching solenoid valve 43 is controlled to be opened, thereby controlling the frame pressing mechanism 4 with the help of the hydraulic fluid in the travel hydraulic circuit. To this end, the switching solenoid valve 43 may be arranged in such a hydraulic pipeline, which is connected between the input end of the travel hydraulic circuit for driving the actuator of the travel mechanism 13 (especially the hydraulic motor for driving the travel crawler) and the input end of the frame pressing hydraulic circuit for driving the actuator of the frame pressing mechanism 4. In this way, by changing the position of the switching solenoid valve 43, the hydraulic fluid flow in the same hydraulic circuit or hydraulic subsystem can be guided to the actuator end of the travel hydraulic circuit or to the actuator end of the frame pressing hydraulic circuit, thereby enabling the travel mechanism 13 and the frame pressing mechanism 4 to share a set of basic hydraulic subsystems.

[0032] In the case where a walking pedal (not shown) which is usually used to operate the walking mechanism 13 is provided in the cab 12, the walking pedal is connected to both the walking hydraulic circuit and the frame pressing hydraulic circuit by signals via the controller 2, so that when the position of the switching solenoid valve 43 is changed to direct the hydraulic fluid flow to the execution end of the frame pressing hydraulic circuit, the frame pressing mechanism 4 can be operated by the walking pedal, especially the upward and downward movement of the frame pressing mechanism 4 can be controlled. For example, when the walking pedal is in a normal state, the frame pressing mechanism 4, especially its two clamping claws 41, can be located at the lowest point or the highest point. The upward or downward movement stroke of the two clamping claws 41 of the frame pressing mechanism 4 is controlled by the stroke of stepping on the walking pedal.

[0033] In the case where a joystick is provided in the cab 12, two buttons, namely a first button 51 and a second button 52, may be provided on one of the handles, especially the right handle 5. Figure 2 As shown. The first button 51 can be connected to the confluence solenoid valve 42 signal to serve as a switch for opening and closing the confluence solenoid valve 41 at any time. For example, it can be set that the confluence solenoid valve 42 is opened when the first button 51 is pressed, and the confluence solenoid valve 42 is closed when the first button 51 returns to its original position. The second button 52 can be connected to the switching solenoid valve 43 signal to serve as a control switch for changing the position of the switching solenoid valve 43. For example, it can be set that when the second button 52 is pressed, the switching solenoid valve 43 is placed in a position to direct the hydraulic fluid flow to the press frame mechanism 4, and when the second button 52 returns to its original position, the switching solenoid valve 43 is in a position to direct the hydraulic fluid flow to the walking mechanism 3.

[0034] Specifically, Figure 3In this embodiment, the first button 51 and the merging solenoid valve 42 can be electrically connected through the relay 46, and the second button 52 and the switching solenoid valve 43 can be electrically connected through the relay 45, so that the opening and closing or switching of the merging solenoid valve 42 and the switching solenoid valve 43 can be controlled by a small current.

[0035] Preferably, see Figure 2 , a first dial wheel 53 may also be provided on the right handle 5. Figure 3 The first dial 53 can be in the form of a variable resistor as shown in the figure, and is connected to the controller 2 by signal. The first dial 53 is constructed and arranged to be able to be dialed from the central neutral position (idle position) to the two sides in two opposite directions, and can thereby control the movement, especially the rotation, of the shearing mechanism 3 via the shear hydraulic circuit. For example, when the first dial 53 is dialed from the neutral position to the Figure 2 When the left side of the slider is turned—this corresponds to the variable resistor Figure 3 The shearing mechanism 3 will rotate to the left, and the greater the amplitude of the first dial wheel 53 being dialed, the greater the speed at which the shearing mechanism 3 rotates to the left. Figure 2 When the right side of the first dial wheel 53 is toggled, the shearing mechanism 3 will rotate rightward, and the rotation speed of the shearing mechanism 3 depends on the toggling amplitude of the first dial wheel 53.

[0036] Similarly, a second dial wheel may be provided on the handle, and the second dial wheel may be Figure 3 As shown in the figure ("push wheel 2" in the figure), it is in the form of a variable resistor and is connected to the controller 2 by signal. The second push wheel can also be constructed and arranged to be able to be pushed from the neutral position to both sides in two opposite directions, and can thereby control the opening and closing of the two clamping claws 41 of the pressing frame mechanism 4 and their movement speeds respectively through the pressing frame hydraulic circuit. Preferably, the second push wheel can be set on a handle different from the above-mentioned right handle 5, for example, on the left handle.

[0037] Of course, according to actual needs, the first button 51 and the second button 52 and the first dial 53 and the second dial may also be arranged at different positions from those in the above embodiment. For example, the first and second buttons 51 and 52 may be arranged on different handles, such as the right handle 5 and the left handle, respectively. For another example, the first dial 53 and the second dial may be arranged on the same handle.

[0038] Preferably, a touch screen 7 connected to the controller 2 by signal can be provided in the cab 12, and the touch screen 7 can be used for the operator to input data required for the operation of the automobile dismantling machine, such as the preset shearing force of the shearing mechanism 3, and the input preset shearing force can be transmitted to the controller 2 through the CAN data line. Thus, the controller 2 can control the maximum shearing force of the shearing mechanism 3 when working according to the input preset shearing force. Advantageously, the preset shearing force can be determined according to the thickness of the plate of the scrapped automobile to be dismantled. For example, when a vehicle with a thicker plate such as a truck is to be dismantled, a larger preset shearing force can be input.

[0039] Specifically, Figure 3 As shown, the shearing hydraulic circuit may include a pilot proportional valve 31, especially an electromagnetic proportional valve, electrically connected to the controller 2. The opening and closing of the pilot proportional valve 31 can be controlled by moving the right handle 5 forward and backward (pushing forward and pulling backward), thereby controlling the opening and closing of the two shearing jaws 34 of the shearing mechanism 3; and the opening of the pilot proportional valve 31 can also be adjusted according to the forward and backward movement amplitude of the right handle 5, thereby adjusting the shearing force of the shearing mechanism 3 and specifically the two shearing jaws 34 thereof. The shearing hydraulic circuit may also include a rotary proportional valve 32, especially an electromagnetic proportional valve, electrically connected to the controller 2, so that the rotation speed or amplitude of the shearing mechanism 3 can be adjusted by, for example, changing the opening of the rotary proportional valve 32 in response to the toggle amplitude of the first dial 53. The shearing hydraulic circuit may also include a relief proportional valve 33, especially an electromagnetic proportional valve, electrically connected to the controller 2, so that the controller 2 can control the shearing force of the shearing mechanism 3 by changing the opening of the relief proportional valve 33.

[0040] Still see Figure 3 The frame pressing hydraulic circuit may include a frame pressing proportional valve 44, in particular an electromagnetic proportional valve, electrically connected to the controller 2, so as to adjust the opening angle or clamping force of the two clamping jaws 41 of the frame pressing mechanism 4 by, for example, changing the opening degree of the frame pressing proportional valve 44 in response to the toggle amplitude of the second dial.

[0041] Industrial Applicability

[0042] The excavator-based automobile dismantling machine disclosed in the present invention is particularly suitable for dismantling automobiles in a suitable working space. The automobile dismantling machine can be flexibly moved and can adapt the space and shear force size according to the model and material of the dismantled automobile.

[0043] Below Figures 1 to 3 Taking the illustrated embodiment as an example, the operation of the excavator-based automobile dismantling machine of the present disclosure is briefly described.

[0044] After the automobile dismantling machine reaches the workplace through the traveling mechanism 13 and is in position, by operating (for example, pressing) the second button 52 on the right handle 5, the switching solenoid valve 43 can be changed in position via the controller 2, thereby introducing the hydraulic fluid flow originally flowing into the execution end of the traveling hydraulic circuit into the execution end of the press frame hydraulic circuit, so as to allow the press frame mechanism 4 to be operated.

[0045] By operating the second dial of the left handle, the opening degree of the press frame proportional valve 44 can be controlled via the controller 2, thereby, for example, controlling the opening angle of the two clamping jaws 41 of the press frame mechanism 4. In addition, by stepping on the walking pedal in the cab 12, the two clamping jaws 41 of the press frame mechanism 4 can be controlled by the controller 2 to move up and down so that the two clamping jaws 41 can clamp the scrapped car to be dismantled, so as to facilitate the subsequent shearing operation of the scrapped car by the shearing mechanism 3.

[0046] After the shearing mechanism 3 has been placed on the scrapped car clamped by the pressing mechanism 4, the right handle 5 can be pushed forward or backward by a certain amplitude, so as to open the two shearing jaws 34 of the shearing mechanism 3 and make them clamp and shear the car part to be disassembled with appropriate force. At the same time, by operating the first dial wheel 53 on the right handle 5, the shearing mechanism 3 can be rotated left and right, so as to separate the sheared car part from the rest of the car.

[0047] According to the characteristics of the car model and material to be disassembled, the operator can input the preset shearing force of the shearing mechanism 3 through the touch screen 7, and the touch screen 7 can transmit the preset shearing force to the controller 2 through the CAN data line, so that the controller 2 can control the actual shearing force of the shearing mechanism 3 according to the preset shearing force and through the overflow proportional valve 33. The matching of the actual shearing force and the sheared material advantageously reduces unnecessary overflow of the hydraulic fluid, thereby reducing the fuel consumption of the car dismantling machine.

[0048] Compared with the prior art, the automobile dismantling machine based on the excavator of the present disclosure can introduce the hydraulic fluid flow in the idle circuit other than the shearing hydraulic circuit into the shearing hydraulic circuit through the merging solenoid valve 42, thereby increasing the flow rate of the hydraulic fluid flow in the shearing hydraulic circuit and improving the dismantling speed. Moreover, the automobile dismantling machine can also introduce the hydraulic fluid flow in the walking hydraulic circuit into the frame pressing hydraulic circuit through the switching solenoid valve 43, thereby allowing the walking mechanism 13 and the frame pressing mechanism 4 to share the hydraulic fluid, reducing the difficulty and cost of converting a conventional excavator into the automobile dismantling machine of the present disclosure.

[0049] For those skilled in the art, various modifications and variations may be made to the embodiments disclosed above without departing from the scope or spirit of the utility model. Other embodiments of the utility model will be apparent to those skilled in the art from the practice of the utility model disclosed in this specification. This specification and the examples disclosed therein should be considered to be illustrative only, and the true scope of the utility model is specified by the appended claims and their equivalents.
