Description

The present application claims the benefits of US Provisional Patent Application No. 62 / 675,540 filed May 23, 2018, which is hereby incorporated by reference in its entirety.

This disclosure relates to a crusher. Such a crusher can be used to grind bulk materials.

Slow crushers may be used to reduce the size of certain waste pieces, such as large landfill waste. U.S. Pat. No. 9,573,137 and U.S. Patent Publication No. 2015/0217299 are examples of such crushers. These crushers are robust machines built with heavy parts due to the high loads and forces applied to the equipment during the crushing process. Waste is often fed from the top of the crusher, typically by dropping the material into the hopper with a front end loader. The hopper accommodates the material with the rotor / drum, which is usually located below the hopper, rotating at a speed that varies from zero RPM to 40 RPM. The crusher rotor has multiple hard teeth, which engage with the waste material and eventually push the material through the toothed comb to cause shearing and tearing of the material. Then, the finely crushed waste falls to the conveyor for discharge. A screen may be used between the rotor and the conveyor to control the size of the material discharged from the crusher. The screen allows small pieces to pass through while preventing large pieces from being ejected through the through conveyor. Large pieces that do not pass through the screen are recirculated by the rotor to the hopper for further reduction in size.

Due to the harsh equipment operating conditions, the cutting machine components require regular maintenance and cleaning. Accessibility to the rotor, screen, and comb of the crusher is crucial for efficient maintenance and optimization of equipment usage. It is extremely difficult to design a crusher that is structurally complete and is a crusher that takes efficient inspection into consideration. Therefore, it is necessary to ensure accessibility for any necessary maintenance activities of the crusher component and to ensure that the crusher has a robust design that can improve equipment life.

It has 116 and is configured such that the concave curvature bends around the cylindrical reference boundary 44 of the crusher rotor 38 when the screen unit 100 enters the installation position. The screen portion 102 has a through hole or a pattern of holes that allows separation of the crushed waste material and serves to limit the size of the crushed material that passes through the screen unit 100 towards the lower outlet 33. Is desirable.

It is rotated around a shaft 119 by an activator such as a hydraulic cylinder 124 to move between the second positions. The lift arm 120 is adjacent to the first side surface of the crusher box 22 to engage with one or more first pin structures 110 of the screen unit 100 and to move or lift the screen unit 100 to the installation position. And may be arranged. The lift arm 120 causes the first end 112 of the screen unit 100 to engage with the active stopper 130 of the crusher box 22 when the screen unit 100 is lifted to the installation position. As shown in FIGS. 23 and 27, the active stopper 130 may be defined by the active stopper structure of the crusher box 22, in which case the first end 112 of the screen unit 100 is the screen unit 100. It includes a notch 132 that accepts an active stopper structure when moved or lifted to the installation position. FIG. 25 shows that the second end 114 of the screen unit 100 is supported on the inspection platform 36 when the screen unit 100 is in the installation position.

As shown in FIGS. 37-41, the crusher box 22 of the screen 100 stops the movement of the screen 100 in the screen loading direction 106 when the screen unit 100 is moved to the installation position by the lift arm 120. A first active stopper 130a engaging at one end may be included on the first side surface of the crusher box 28.

Each screen retention link 140 has a first end pivotally connected to the access door 46 and a second end supported on the inspection platform 36. After the screen unit 100 is installed under the crusher rotor 38, when the access door 46 is closed, the second end of each of the screen holding links 140 slides across the inspection platform 36 and the second end 114 of the screen unit 100. Engage with and hold the screen unit 100 in the installation position. To facilitate removal of the screen unit 100 from the crusher box 22, the access door 46 is opened to displace each of the screen holding links 140 from the screen unit 100 to provide an open space 64 for the side access area 62. The lift arm 120 is then lowered to lower the screen unit 100 from the installation position to the scaffolding position under the crusher rotor 38. Then, the screen unit 100 is slid in the screen unloading direction 142 extending away from the first side wall 28 and ejected from under the crusher rotor 38. Then, the screen unit 100 may be lifted vertically and taken out of the crusher box 22 through the open space 64 of the side access area 62. The screen unit 100 may further include one or more second pin structures 144 at the second end 114 of the screen unit 100, as seen in FIGS. 16 and 27. When the access door 46 is closed, the second end of each of the screen retaining links 140 engages one or more second pin structures 144 (see FIG. 43).

The crusher 20 may further include a flow control comb portion 150 pivotally connected to the first side wall 28. As shown in FIGS. 1 and 3, the flow control comb portion 150 meshes with the crusher rotor 38, and the material to be crushed is downward from the upper hopper 32 to the crusher rotor 38 and the first side wall 28. Prevents moving into the area between.

It has a comb element that can be pivoted upwards.

FIG. 34 depicts a control system 300 for monitoring various parameters of the crusher 20 and controlling various systems of the crusher 20. The control system 300 may include a controller 301 including a computer comprising at least one central processing unit (“CPU”) having processing performance, a system memory, and a system bus connecting the system memory to the CPU. good. System memory includes random access memory (“RAM”) and read-only memory (“ROM”). The ROM stores a basic input / output system that stores basic routines that help transmit information between elements in the control computer, for example during startup. The control computer may further include a mass storage device. Mass storage devices can store software instructions and data. The system memory may include instructions that cause the electronic computing device to execute various programs from the control system 300 when executed by the processing unit. In other embodiments, the controller may include one or more microprocessors and may include digital or analog control.

In certain embodiments, the control system 300 may interface with the powertrain 56 (ie, drive system) to control the rotation of the crusher rotor 38. The control system 300 further has different functionality for monitoring the operation of the crusher 20 and for enhancing the operation of the crusher 20 (eg, automatic reversal of the rotor during overload condition detection; screen presence parameter detection). It may be interfaced with various sensors (eg, pressure sensor, proximity sensor, torque sensor, rotational speed sensor) to perform high release pressure actuation mode of the comb portion of time; etc.). The high release pressure actuation mode of the crusher comb may be manually initiated by the operator when the screen is not installed, or the high release pressure actuation mode of the crusher comb is automatic when the installation of the screen 100 is indicated. It may be started as a target. In certain embodiments, the control system 300 may include a controller 301 that controls the operating mode of the crusher comb portion 58. The crusher comb portion 58 may be operable in the first high pressure release operation mode or the second low pressure release operation mode.

When the crusher comb 58 is in the first high release pressure operating mode, a first predetermined pressure is observed in the crusher comb 58 and is generated by the material being crushed, the crusher comb 58 is a crusher comb. It is movable from the crushing position to the release position to allow obstacles (eg, non-crushable pieces of material) to pass between the 58 and the crusher rotor 38. When the crusher comb 58 is in the second low release pressure operating mode, a second predetermined pressure is observed in the crusher comb 58 and is generated by the material being crushed, the crusher comb 58 is a crusher comb. It is movable from the crushing position to the release position to allow obstacles to pass between the 58 and the crusher rotor 38. The second default pressure is lower than the first default pressure. For example, the first default pressure can be in the range of 2,500 psi to 2,700 psi and the second default pressure can be in the range of 1,100 psi to 1,600 psi.

In some cases, the first high pressure release mode has the crusher comb 58 in the hydraulic lock actuation mode in which the crusher comb 58 is prevented from moving from the crush position to the release position in response to an overload condition. Can include that. In certain embodiments, the controller 301 may be adapted to activate the automatic reversal of the crusher rotor 38 in either or both of the first operating mode and the second operating mode.

As previously described and depicted in FIGS. 8-9 and 22, the crusher 20 includes one or more hydraulic cylinder devices 87 for holding the crusher comb 58 in the crushing position. (Multiple hydraulic cylinder devices 87 are drawn). Each hydraulic cylinder device 87 includes a hydraulic cylinder and a piston rod capable of reciprocating within the hydraulic cylinder. With reference to FIG. 34, one or more fluid lines 320 fluidly connect the hydraulic cylinder device 87 to the accumulator 340. The pressure in the accumulator 340 is set by the pressure controller 341 controlled by the controller 301. A valve 307 is located between the accumulator 340 and the hydraulic cylinder device 87 along the fluid line 320. When in either the first or second mode of operation, the valve 307 is opened to provide fluid communication between the hydraulic cylinder device 87 and the accumulator 340.

When in either mode, when the force applied to the comb 56 by the rotor 38 produces hydraulic pressure in the hydraulic cylinder that exceeds the set system pressure or the set accumulator pressure, the hydraulic fluid is pumped from the hydraulic cylinder 87 to the accumulator. The hydraulic cylinder device 87 is urged to retract to flow towards 340. The pull-in of the hydraulic cylinder device 87 moves the comb portion 56 from the crushing position to the releasing position. When the load on the comb portion 56 has subsided, the hydraulic pressure from the accumulator 340 extends the hydraulic cylinder device 87, thereby returning the comb portion 56 to the crushing position. The accumulator 340 forms part of the hydraulic release device 350 of the system.

In certain embodiments, the control system 300 is adapted to monitor parameters to indicate the presence or absence of a screen at the screen mounting location under the rotor 38. In certain embodiments, the parameter is a read from a sensor (eg, proximity sensor) and is the actual presence of the screen (eg, indicated by a positive sensor read) or the absence of the screen (shown by a negative sensor read). It may be read from a sensor that detects. In another embodiment, the parameter may be a read from a sensor that senses a condition indicating that the screen is mounted at the screen mounting location. For example, in the system of FIG. 34, the sensor 302 (eg, proximity sensor, rotational position sensor, etc.) monitors the position of the lift arm 120. In this case, the state indicating that the screen is in place under the rotor 38 is that the arm 120 is positioned in the upper position (see FIG. 25). The controller 301 interfaces with the sensor 302 and therefore constantly monitors whether the screen is installed or not based on the position of the lift arm 120. Based on the sensed status of the parameters regarding the presence of the screen under the rotor 38, the controller can selectively enable the first or second mode of operation for the system.

For example, if the sensed parameter indicates the presence of a screen, the system will be operated with the comb 58 in the first or higher pressure release mode. In contrast, if the sensed parameter indicates the absence of the screen, the system will be operated with the comb 58 in a second or lower pressure release mode. In this way, the control system 300 sets the crusher comb portion 58 to the first operating mode and automatically operates the crusher 20 when the parameter indicates that the screen unit 100 is installed at the screen mounting location. to enable. In addition, the control system 300 automatically activates the crusher 20 by setting the crusher comb 58 to a second operating mode when the parameters indicate that the screen unit 100 is not installed at the screen mounting location. Make it possible. The control system 300 can automatically program the functionality of the powertrain 56 to operate in the automatic reversal mode when an overload condition is detected in the rotor 38.

From this, referring to FIG. 50, a first embodiment of the hydraulic circuit that can be operated in the above-mentioned comb release operation mode is provided. Controller 301 receives input from one or more proximity sensors 302 monitoring the position of the lift arm 120. In the illustrated circuit, the arm 120 located adjacent to the proximity sensor 302 indicates the presence of the shield unit 100 so that the circuit operates in the first high pressure release actuation mode. Will be controlled. Further, the controller 301 receives an input from the system pressure sensor 420 that determines when the system reaches the first predetermined pressure, and if the pressure is higher than the first predetermined pressure, the comb portion 58 overcomes the system pressure and moves to the release position. It should work. The controller 301 outputs a signal for controlling a three-position valve 424 (eg, an implementation valve). By opening and closing the valve 424, more fluid is pushed into the accumulator 340 (ie, from the tank 428 by the pump 432), or by removing the fluid from the system, the system pressure reaches the desired predetermined pressure. Can be controlled by. The circuit is provided with a pressure release valve or safety device block 436, which can be set to a pressure higher than either the first or second predetermined pressure (eg, 2,755 psi).

FIG. 51 depicts a second embodiment of the hydraulic circuit that can be operated in the above-mentioned comb release operation mode. Similar parts are given similar reference numerals. In the case of the circuit of FIG. 51, the input of the proximity sensor 302 to the controller 301 is the same, and the pressure sensor 420 reads the pressure in the accumulator 340. The controller 301 outputs a signal for controlling the pressure release setting of the pressure control valve 440. Depending on the mode of operation, the controller 301 can set the pressure release setting of the valve 440 to either the first default pressure or the second default pressure depending on the input from the proximity sensor 302. The pressure in the accumulator 340 can be maintained at a low pressure (eg, 750 psi) suitable for returning the comb 58 to the crushed position after the overload condition has subsided. Although not shown, the circuit is provided with a pressure release valve or safety device block, which can be set to a pressure higher than either the first or second predetermined pressure (eg, 2,755 psi).

As shown in FIGS. 34, 45A, and 45B, the powertrain 56 (ie, drive system or drivetrain) for the low speed crusher may include the engine 309 (which may include the engine flywheel 310). It includes a reversible gear transmission 312, which is connected to the output shaft of the engine 309. The reversible gear transmission 312 houses a hydraulic clutch. An embodiment of a reversible transmission is disclosed in US Pat. No. 6,666,312, which is hereby incorporated by reference in its entirety. The input shaft of the reversible gear transmission 312 is connected to the output shaft of the engine 309 and the output shaft of the reversible transmission 312 is connected to the optional fluid coupler 314. The fluid coupler 314 is connected to the flywheel 315, both of which are connected to the input shaft of the gear reduction unit 316. The flywheel 315 is provided to level the load spikes commonly observed during the operation of the crusher and is the size to level the load spikes. The output shaft of the gear reduction unit 316 is drivably accepted by the crusher rotor 38 to drive the rotation of the rotor 38. Details and aspects of the drivetrain 56 are discussed below.

In one embodiment, the fluid coupler 314 can deliver torque from the transmission 312 to the gear reduction unit 316 by hydraulic fluid pressure, and further, fluid coupling is used rather than a direct mechanical connection. Therefore, it can also function as a torque overload protection device (for example, if the torque exceeds a predetermined maximum value, the fluid coupler 314 will spin). In another embodiment without the fluid coupler 314, the clutch of the reversible gear transmission 312 will perform the clutching function of the fluid coupler 314.

The gear reduction unit 316 can include a planetary gear set. The gear reaction unit 316 reduces the rotational speed of the crusher rotor 38 to a desired operating speed when the engine 309 is operating at the rated speed. The output shaft of the gear reduction unit 316 is coupled to the rotor drive shaft or, in the embodiment depicted, can be driven into the female receiving hole of the rotor 38 aligned along the rotating shaft 40 of the crusher rotor 38. Has been accepted by. The controller 301 can interface with the transmission 312 to control the direction in which the torque is applied to the fluid coupler 314. In this way, by interfacing with the transmission 312 and controlling the mode of operation of the transmission 312 (eg, forward or reverse), the controller 301 rotates the rotor 38 clockwise and counterclockwise around the axis of rotation 40. It can be driven selectively in the direction.

In the embodiment depicted in FIG. 45A, the centerline of the engine crankshaft is below the centerline of the output shaft of the transmission 312 (eg, about 9.75 inches below). Further, the center line of the output shaft of the transmission 312 is the center line of the input shaft of the fluid coupler 314 and the center line of the input / output shaft of the gear reduction unit 316, each of which is the same axis as the rotation shaft 40 of the rotor 38 in the vertical direction. It is placed below or below. A drive shaft 444 with a U-joint 448 interconnects the output shaft of the transmission 312 to the input shaft of the fluid coupler 314 (or to the input shaft of the gear reduction unit 316 in embodiments without the fluid coupler 314) and is vertically offset. It corresponds to. These vertical offsets in an in-line drive arrangement without any belt drive mechanism maximize the height of the lower discharge chute 34 to allow optimum material outflow from below the crusher 20 while still maximizing the height of the crusher. Helps reduce the overall shipping height of the 20. Note how the engine 309 is above the hitch 452 of the fifth wheel hitch attachment and has an output shaft centerline lower than the rotating shaft 40 of the rotor 38.

The system can further include sensing functionality to determine when the crusher is experiencing an overload condition. For example, the controller 301 can interface with a pressure sensor 368 that senses the pressure corresponding to the pressure in the hydraulic cylinder device 87. An overload condition is detected when the perceived pressure exceeds a predetermined pressure threshold. The controller 301 may further interface with a rotation speed sensor 370 that senses the rotation speed of the crusher rotor 38. An overload condition is detected when the sensed rotation speed of the rotor 38 drops below a predetermined threshold. The rotational speed sensor 370 can sense the actual rotational speed of the crusher rotor 38 (eg, by sensing the rotational speed or output of the rotor drive shaft of the planetary gearset 316), or the speed of the crusher rotor 38. Other parameters indicating (for example, the rotation speed of the input shaft of the planetary gear set 316 or the rotation speed of the output side of the fluid coupler 314) can be sensed. In one embodiment, the rotational speed sensor 370 can be located between the output side of the fluid coupler 314 and the input shaft of the planetary gearset of the gear reduction 316.

As previously suggested, the control system 300 includes a controller 301 for controlling the drive system components. The inputs for the control system 300 are monitored based on the rotational speed of the crusher rotor 38, the oil pressure in the hydraulic cylinder device 87, the rotational speed of the input side of the fluid coupler (eg, via CAN, the output RPM of the transmission). ), And the presence or absence of the screen unit 100 may be included. The output of the control system 300 controls to control the direction of rotation of the crusher rotor 38 and whether the system is in the first high pressure release operating mode or the second low pressure release operating mode. It may include controls for doing so. The control system 300 may be used in a state where the screen unit 100 is in a predetermined place, or may be used in a state where the screen unit 100 is not in a predetermined place. As described in detail above, when the screen unit 100 is in place, the hydraulic cylinder device 87 should try to keep the crusher comb 58 in place until the first predetermined pressure is reached. Therefore, the ability to release the crusher comb 58 to protect the screen unit 100 from damage is minimized. If the screen unit 100 is not in place, the crusher comb 58 will be released when the hydraulic cylinder device 87 reaches a second lower predetermined pressure.

One embodiment of control logic suitable for use with the crusher 20 is shown in FIG. At step 500, the system determines if the presence of a screen installed under the rotor 38 is indicated. If the presence of the screen is not indicated, the system proceeds to step 502, a second low pressure release mode is enabled, and the rotor 38 is driven in the forward rotation direction to perform the crushing operation (see step 508). ). If the presence of a screen is indicated, the system proceeds to step 506 and the first high pressure release actuation mode is enabled. The system then proceeds to step 508, where the rotor is driven in the forward rotation direction to perform the crushing operation. In each operating mode, the automatic reversal function is enabled. At step 510, the system senses whether an overload condition has been detected in the rotor 38. If no overload condition is detected, the system returns to step 508. In contrast, if the system detects an overload condition, an automatic reversal cycle is initiated to eliminate any possible barking between the comb 58 and the rotor 38.

The control system 300 further includes a step of controlling an automatic reversing function that automatically reverses the rotation direction of the crusher rotor 38 from the forward rotation volume reduction direction to the reverse rotation direction when an overload state is detected. May be good. The control system 300 will try to automatically reverse the crusher rotor 38 if stall or excessive torque is detected. A mechanical drive system will attempt to automatically reverse the crusher rotor 38 by utilizing a reversing gearbox with a hydraulic shift clutch. Control over the crusher 20 may further include a manual reversal button that pushes the feedstock at the discretion of the operator. The automatic reversal function can occur independently of whether or not the screen unit 100 is installed.

When the automatic reversing function is activated and the RPM of the speed of the crusher rotor 38 drops below the threshold speed setting, the automatic reversing sequence is started and the crusher rotor 38 is reversed. The engine 309 attempts to reduce the rotor speed via automatic control by the controller, eventually reaching the RPM level or ENGAGE SPEED (engagement speed) at which the fluid coupling 314 or clutch can be disengaged. Become. When the rotor speed reaches ENGAGE SPEED, the transmission 312 shifts to the REVERSE setting. The fluid coupling 314 or clutch is then engaged and then the engine speed is raised to maximum RPM over the time VERSERSE TIME (X) set by the control function (rotor rotates in reverse). When the REVERSE TIME (X) is complete, the engine speed is reduced to ENGAGE SPEED and the fluid coupling 314 or clutch is disengaged. While the engine 309 is in ENGAGE SPEED, the transmission 312 shifts to forward rotation, the fluid coupling 314 or clutch is engaged and the engine speed increases to full speed in an attempt to crush the material. The threshold speed setting is for the components of the powertrain 56 that may include the crusher rotor 38, the crusher comb 58 component, the engine 309, the transmission 312, the fluid coupler 314, the flywheel 315, and the gear reduction unit unit 316. Based on torque level to prevent damage.

The number of rotor reversal trials can be set by the operator. For example, if the number of rotor reversal attempts is set to 3, control system 300 will attempt up to 3 reversal sequences before the rotor automatically shuts down for any necessary maintenance or operator gaze. And. The operator may further manually initiate the rotor reversal by pressing the reversing button as needed. The control system 300 may also use additional inputs to control the release mechanism of the crusher comb portion 58. Such input variables may include elapsed time at low rotor RPM rates as well as measured fluid coupling temperature. As shown in FIG. 36, after the rotor reverses over a set time, the rotor rotates forward again to attempt crushing and the reverse sequence count is reset to zero.

In one embodiment, the control system 300 comprises a reversing sequence in which the rotor is reversed and then returned to normal rotation. The rotor must be operating at low speed to complete the reversal sequence. After a preset delay of about 250 ms, the control system 300 disengages the fluid coupling 314 or clutch and the speed at which the engine can engage the fluid coupling 314 or clutch, ie ENGAGE SPEED. Wait for the engine to slow down. The control system 300 then shifts the transmission to REVERSE and engages the fluid coupling 314 or clutch. The engine speed is then increased to maximum RPM. The rotor 38 reverses over the time set by the parameter REVERSE TIME (x), i.e., the time the rotor 38 reverses for each given reversal attempt. Each reversal time is individually adjustable, and each reversal time is longer than the previous reversal time (ie, REVERSE TIME (2) is longer than REVERSE TIME (1)). The control system 300 releases the high engine speed. After another delay, which may be approximately 250 ms, the control system 300 then disengages the fluid coupling 314 or clutch. When the engine slows down to ENGAGE SPEED, the control system 300 shifts the transmission to the FORWARD setting, then the fluid coupling 314 or clutch engages and the engine speed rises to the maximum RPM setting. Occurs. At this point, the rotor 38 is now rotating in a forward rotation motion.

One embodiment of logic for an automatic reversal program is illustrated in FIG. 36, which can proceed as follows. First, an adjustable rotor speed threshold in RPM is set, specifically the rotor speed at which the rotor reversal sequence will be triggered. This speed setting is called the variable name DROOP. The number of reversal attempts in the gradual reversal cycle sequence is set based on the input from the operator. At step 600, the rotor is operated in forward rotation drive mode. At step 602, the system determines if the sensed forward rotor speed is above DROOP. If the rotor speed is below DROOP, the crusher initiates a reversal cycle sequence (see step 604) to dispel the debris trapped in the crusher comb 58 and / or the screen unit 100 and in memory. The reverse count will be added to the reverse count log. When the operator-programmed time length for the initiated reversal cycle sequence expires, the system checks to see if the reversal count stored in the reversal count log exceeds the default maximum number of attempts (step 606). reference). If the maximum number of reversal attempts reaches DROOP without the appearance of a positive rotor rotation exceeding DROOP, the system moves to step 608, the rotor clutch is disengaged, and due to untreated debris or feed material. A message is displayed to inform the operator that the machine will be shut down. If the maximum number of reversal attempts has not been reached, the system returns to step 600 and the rotor is rotated in the positive direction. If the forward rotor speed fails to exceed DROOP, the system returns to step 602 and the protocol described above is repeated. If the forward rotor speed exceeds DROOP, the system proceeds to step 610. At step 610, the system continues to operate in the forward rotation drive mode and resets the reverse rotation of the reverse rotation count log to zero. The system then returns to step 600.

An example of automatic shutdown from the control system 300 can be implemented as follows. When the operator presses the automatic button for 500 milliseconds, the operator display immediately displays a message that reads "The automatic crushing is canceled". The engine 309 attempts to reduce the rotor speed to RPM levels low enough to disengage the clutch. As soon as the clutch is disengaged, the operator display will give a different prompt reading "Do you want to disengage the conveyor? Y / N" and then the control system will be shut down.

The operator may also manually perform an individual function that can put the crusher 20 into the crushing state. This requires the operator to put the crusher into the specified automatic crushing setting. When the operator presses the rotor forward button for approximately 500 ms to put the crusher 20 into this setting, the operator display displays a message indicating that the conveyor is not running. This initiates a countdown sequence for disengaging the rotor 38, which will be indicated on the screen by a message and an accompanying simultaneous alarm sequence. The display reads "Rotor engaged" for 2 seconds and then switches to the main menu. The operator must then set the maximum engine RPM by pressing the engine high button. When the rotor speed is above the RPM level specified by the system, the crusher automatic crushing setting will be performed.

52-54 show that the front surface or end face wall 800 of the upper hopper 32 adjacent to the first end face wall 24 facilitates feeding the material to be crushed into the upper hopper 32 and to the rotor 38. An example of a crusher 20 formed with a recess 804 is depicted. The recess 804 is defined by a rearwardly sloping wall 808 located above the first end wall 24. The first and second wall portions 812 and 816 are symmetrically angled forward and inward from the slanted wall 808 toward the longitudinal centerline of the crusher 20, respectively. The first and second walls 812 and 816 may be provided with optional water nozzles 818 (FIGS. 53 and 54) for spraying water into the upper hopper 32 for dust control. The third and fourth wall portions 820 and 824 extend forward from the first and second wall portions 812 and 816, respectively, until they intersect the fifth wall portion 828 substantially parallel to each other. The fifth wall portion 828 is inclined rearward and downward toward the rotor 38 from the upper surface wall 832 of the crusher 20 until it intersects the vertically extending portion of the first end face wall 24. As most clearly shown in FIG. 54, the slope of the fifth wall portion 828 is designed to direct the material towards the anterior end of the rotor 38, and in the illustrated embodiment the fifth. The waste that slides along the wall portion 828 of the rotor 38 is slanted so that it will be engaged by the rotor teeth 42 in the first and / or second row of the front row on the rotor 38. Reference line 836 (FIG. 54) depicts how the plane enclosing the fifth wall 828 intersects the rotor teeth 42 in the second row on the rotor 38. The reference line 836 drawn forms an angle of about 45 degrees with respect to the vertical.

The recess 804 distributes the waste more evenly along the length of the rotor 38, especially along the front end of the rotor 38, thereby utilizing the front end of the rotor 38 and its teeth 42 for crushing efficiency. Helps to maximize. In other prior art crushers, the front end of the rotor has almost no access to the waste inserted into the upper hopper due to the presence of the overhang structure. The recess 804 serves to eliminate structural obstacles to direct contact with the end portion of the rotor 38 as the waste falls downward towards the rotor.

The crusher 20 may further include a mechanism for adjusting the clearance between the crusher comb 58 and the rotor 38 when the access door 46 is in the closed and latched position. This clearance ultimately regulates the clearance between the comb teeth 60 and the rotor teeth 42 and can be adjusted to compensate for the different types of material crushed by the crusher 20. FIGS. 55-57 schematically depict how the adjusting mechanism interacts with the crusher comb 58 to set clearance. The adjustment mechanism illustrated includes an eccentric adjustable block assembly 900 attached to each of the first and second end walls 24, 26. 55-57 depict a block assembly 900 attached to a first end wall 24, with another block assembly 900 attached to a second end wall 26 (not shown). (See FIG. 47). FIG. 55 depicts an access door 46 in a partially open position. FIG. 56 depicts an access door 46 in a closed and latched position, provided that the comb 58 is before (or is in the comb open position) fully extended to the crushing position by the hydraulic cylinder device 87.

FIG. 57 depicts a door 46 that is closed and latched, and the crusher comb 58 is extended to the crushing position by the hydraulic cylinder device 87. When in this position, the portion of the crusher comb portion 58 abuts on each block assembly 900, whereby the hydraulic cylinder device 87 pivots the comb portion 58 towards the rotor 38 in setting the desired crushing position of the comb portion 58. The range that can be moved is limited. In other words, the block assembly 900 acts as an adjustable stopper that abuts on the comb 58 to limit the extent to which the crusher comb 58 engages with the rotor 38. As described in more detail below, the orientation / position adjustment of the block assembly 900 limits the range in which the comb 58 can be pivoted towards the rotor 38 by the hydraulic cylinder device 87. Adjust where the block assembly 900 abuts. This allows the operator to adjust the desired clearance between the comb 58 and the rotor 38 for different crushing applications.

58 and 59 are partial cross-sectional views seen from the inside of the cavity accommodating the rotor 38 toward the front surface of the crusher 20, and show the interaction between the front block assembly 900 and the crusher comb portion 58. I'm drawing. The comb portion 58 includes a comb portion stop plate 904 at each end of the comb portion 58 so that it can be positioned adjacent to the end face walls 24 and 26. The stop plate 904 includes an engaging surface 908 configured to selectively abut the block assembly 900. The hydraulic cylinder device 87 shown in FIGS. 58 and 59 is attached to a mounting plate (not shown) that has been removed for clarity in order to see the stop plate 904 and the block assembly 900. Please note that there is.

60-66 depict the block assembly 900 of the first end face wall 24 in detail. The following description applies equally to the block assembly 900 of the second end face wall 26 shown in FIG. First, with reference to FIGS. 60 and 61, the mounting plate 912 is fixed (for example, welded) to the end face wall 24 so that the aperture 914 of the mounting plate 912 is aligned with the aperture 915 having the same configuration as the end face wall 24. The eccentric block 916 includes a first end 918 configured to be inserted through the aperture 915 of the end face wall 24 and through the aperture 914 of the mounting plate 912. The second end 920 of the block 916 is larger in size so that it abuts on the end face wall 24 and cannot pass through the aperture 915 in the end face wall 24. The flange 922 (FIG. 60) is fixed (eg welded) to the mounting plate 912 to accept the first end 918 of the block 916, more specifically the protrusion 924 on the first end 918 of the block 916 is the aperture of the flange 922. Accepted by 926. The block 916 includes a threaded bore 928 at the first end 918 that extends through a protrusion 924 and receives a fastener 930 (eg, a threaded bolt). When the fastener 930 is inserted into the threaded bore 928 and secured, the washer 923 and the washer 932 and so that the block 916 is secured to the end face wall 24 via the engagement between the fastener 930 and the flange 922. / Or the head 934 of the fastener 930 is configured to have dimensions greater than the aperture 926 of the flange 922.

As most clearly shown in FIGS. 62-66, the illustrated block 916 is a four-sided block, whose longitudinal direction is coaxial with the threaded bore 928 at the second end 920. It is eccentric around the axis. The first end 918 of the block 916 is symmetrical about the threaded bore 928 and the longitudinal axis, and the aperture 915 and mounting plate 912 of the end face wall 24 in one of four different rotational positions or orientations. Can be inserted through the aperture 914 of. Similarly, the protrusion 924 is symmetrical about the threaded bore 928 and fits through the aperture 926 of the flange 922 in one of four different rotation positions or orientations. On the other hand, the second end 920 of the block 916 provides the bore 928 to provide four different stop surfaces 936, 938, 940, 942 for engaging the engagement surface 908 of the stop plate 904 on the comb portion 58 side. Is eccentric to. The stop surface 936 is substantially coplanar with the adjacent surface of the first end 918. The stop surface 938 is offset by a first predetermined distance from the adjacent surface of the first end 918. The stop surface 940 is offset from the adjacent surface of the first end 918 by a second predetermined distance that is greater than the first predetermined distance. The stop surface 942 is offset from the adjacent surface of the first end 918 by a third predetermined distance that is greater than either the first or second predetermined distance. The default distance can be selected as desired and can be set in appropriate increments to provide the desired clearance option for stopping the comb 58 with respect to the rotor 38. The block 916 is made of metal so that the stop surfaces 936, 938, 940, 942 can withstand the repeated engagement by the engagement surface 908 and the pressure applied by the hydraulic cylinder device 87. In an alternative embodiment, the block may have a different number of faces and stops to provide the desired number of comb adjustment options.

It is easy to change the desired comb / rotor clearance. The operator loosens and removes the two fasteners 930 (one for each block assembly 900), removes the block 916, and blocks the desired stop surface so that it faces the engagement surface 908 of the stop plate 904. The 916 may be re-installed, and then the fastener 930 may be reinserted and retightened. As best seen from FIG. 59, to assist the operator, the end face 946 of the second end 920 of the block 916 can include a display 950 indicating the amount of clearance provided by each stop plane of the block 916. .. As depicted in FIG. 59, the display 950 is provided on the end face 946 adjacent to each stop plane 936, 938, 940, 942 (eg, etched) number ("0" is the maximum clearance setting). , Where "3" represents the minimum clearance setting).

67-74 show the features of the conveyor system 159, in particular the lower conveyor without the need to remove the outer conveyor 162 from the crusher for inspection or replacement of the conveyor belt and other conveyor components. Explains how the 160 is configured to be removed from its working position under the rotor 38 and discharge chute 34 of the crusher 20. FIG. 67 depicts a state in which the outer conveyor 612 is in its operating position and is pivoted around the base / frame 50 of the crusher 20. The outer conveyor 162 includes an idler roller 950 around which the conveyor belt rotates. FIG. 68 depicts the outer conveyor 162 in its non-operating position, stowed position, or transport position. At this position, the idler roller 950 of the outer conveyor 162 is positioned vertically above or substantially vertically above the top surface 952 of the lower conveyor 160. In order to allow the lower conveyor 160 to be removed from the crusher 20 without the need to remove the outer conveyor 162, the crusher 20 is more vertically downward than the outer conveyor 162 in which the lower conveyor 160 is housed. Specifically, it is designed to be or may be placed below the idler roller 950 of the outer conveyor 162. This allows the lower conveyor 160 to be removed from the crusher 20 in the rear horizontal direction parallel to the rotor shaft 40 by a fork truck or other suitable machine (see FIGS. 72 and 74).

FIG. 69 shows that the lower conveyor 160 is in the descending position, where the top surface 952 interferes with or interferes with the horizontal removal of the lower conveyor 160 beyond the idler roller 950. Well below any other structure of the outer conveyor 162 that should interfere. As seen in FIG. 69, the lower conveyor 160 can be lowered from the operating position with respect to the frame 50 so that a portion of the frame structure of the lower conveyor 160 rests on the frame 50 and the frame 50. It is supported by sliding. 70 and 71 show a conveyor support bracket 954 (two shown in FIG. 70) that support the lower conveyor 160 with respect to the frame 50 of the crusher 20 and allow movement of the lower conveyor 160 with respect to the frame 50. ) Is drawn. As shown in FIG. 71, each support bracket 954 includes a threaded rod 956 that supports one or more retaining nuts 958. The operator can loosen the nut 958 and lower the lower conveyor 160 from the operating position to the descending position. Those skilled in the art will appreciate that other mechanisms may be used instead to support the lower conveyor 160 and allow its movement. The illustrated support bracket 954 is only one embodiment.

After the operator loosens all the holding nuts 958 (on all brackets 954 on either side of the crusher 20), the lower conveyor 160 is lowered to its lowered position and is supported by the surface of the frame 50. The support bracket 954 can then be removed from the frame 50. In the embodiment depicted, the stub shaft on the bracket 954 fixing the bracket 954 to the frame 50 can be removed from the aperture 960 of the frame 50. FIG. 73 depicts a state in which the bracket is removed, and a part of the lower conveyor 160 in the lowered position can be seen through the elliptical aperture 962 of the frame 50.

With the lower conveyor 160 in the lowered position and slidably supported on the frame 50, the operator uses an available machine (eg, fork truck, etc.) to bring the lower conveyor 160 to the lower conveyor 160. It can be slid backward horizontally to at least the position shown in FIG. 74 where the support frame, rollers, and conveyor belts are accessible for repair and / or replacement. The outer conveyor 162 is in its non-operating position or transport position and does not interfere with the removal of the lower conveyor 160. Unlike some prior art crushers, the lower conveyor 160 can be removed from under the rotor 38 as a module without requiring removal or disconnection of the outer conveyor 162 from the crusher frame 50.
