Definitions
- TITLE "Device for securing teeth to tooth adapters of an earth-moving machine through pins"
- the present invention relates to a device for securing implements to heavy machines by means of pins; in particular, said implements may be teeth for earth-moving machines .
- devices which are used for securing implements to such machines by means of pins.
- Such devices can be used in combination with different type of machines, including earth-moving machines .
- excavators With particular reference to the field of earth-moving machines, excavators, for example, are equipped with a bucket or a blade connected to the end of a movable arm for breaking up and moving earth, the characteristics of which may vary extensively.
- the bucket of such machines is generally fitted with one or more teeth, or tips, which can be connected thereto in a removable manner, so that such teeth can be replaced when worn or should they break during use, without requiring the replacement of the whole bucket, which would be a very expensive and difficult task.
- the teeth are secured in different ways to protuberances, also known as tooth adapters, arranged along the lower edge of the bucket.
- An old fastening method requires the use of a pin or key to be forcedly driven with a hammer into a series of holes between the tooth adapter of the bucket and the tooth; once inserted, the pin is received into a deformable element, e.g. a rubber element or ring, which can generate friction that holds the various pieces in position while using the machine.
- Another problem is the low level of safety for operators using hammers or clubs for inserting the pin.
- a further drawback is that such devices work mainly by friction, and the pin has much clearance within the spaces in which it is inserted; therefore, there is more likelihood that the pin might come off, particularly when the bucket is working into hard ground or in the presence of water: in such cases, vibrations and water will remove the thin layer of earth deposited in the interstices between the tooth, the bucket and the fastening device, which is useful for increasing friction and holding the pieces in mutual contact.
- document ES1068766U illustrates a device comprising a partially threaded through pin, intended for cooperating with a threaded washer having a locking means, e.g. a groove, into which an operator inserts a screw or pin for holding it in position, thereby preventing the parts from coming out of their seat.
- a locking means e.g. a groove
- a pin is used which can be manually inserted into and extracted from suitable holes without requiring the use of hammers, clubs or the like; this technology is also referred to as "hammerless”.
- FIG. 1 is a view of an implement connected to a machine by means of the present invention
- FIG. 2 is an exploded view of one example of a device in accordance with the present invention.
- FIG. 3 is a sectional view of the device shown in Figure 2, in a retracted condition
- FIG. 4 is a sectional view of the device shown in Figure 2, in an extracted condition
- FIG. 5 is a sectional view along line V-V of the device shown in Figure 4;
- FIG. 6 is a sectional view of a second embodiment of the device.
- FIG. 7 is a sectional view along line VII-VII of the device shown in Figure 6.
- a device 1 connects an implement 3 to an implement carrier 4.
- implement 3 is a tooth 3
- implement carrier 4 is a tooth adapter 4 of a bucket 5 belonging to an earth- moving machine, e.g. an excavator useful for excavating/moving earth.
- implement carriers 4 in this case tooth adapters 4 of bucket 5, are shaped in such a way as to at least partially enter a cavity formed in implements 3, which are intended for being mounted on the machine and replaced as necessary. It is therefore necessary to use a device capable of firmly keeping implement 3 in contact with implement carrier 4 while the machine is in use.
- “Hammerless” device 1 comprises a pin 10 to be removably inserted through at least one first aperture 12 on an implement 3 and one second aperture 14 on an implement carrier 4 of a machine.
- Device 1 comprises at least one expanding element 20 adapted to reversibly switch between a retracted position, in which said expanding element 20 is at a minimum distance from the longitudinal axis x-x of said pin 10, to an extracted position, in which said expanding element 20 is at a maximum distance from the longitudinal axis x-x of said pin 10.
- expanding element 20 is adapted to reversibly switch from said retracted position to said extracted position by moving in a plane substantially perpendicular to the longitudinal axis x-x of said pin 10.
- expanding element 20 is adapted to reversibly switch from the retracted position to the extracted position by moving transversally relative to the longitudinal axis x-x of pin 10.
- Device 1 further comprises at least one retaining element 22 associated with at least one of said first and second apertures 12, 14, and provided with at least one seat 24 for at least partially receiving said at least one expanding element 20 when said at least one expanding element 20 is in said extracted position.
- Retaining element 22 is associated with at least one of the first and second apertures 12, 14 through methods which are per se known; for example, it is possible that a cavity, also known as "counterbore", is formed on at least one of said first and second apertures 12, 14, into which retaining element 22 can be at least partially inserted.
- Figure 1 shows one advantageous embodiment of the present invention, wherein tooth 3 has a cavity into which tooth adapter 4 is inserted, and two first apertures 12 are present on the faces that delimit the cavity; pin 10 is then inserted through the first apertures 12 on tooth 3 and through the second aperture 14 on tooth adapter 4 of bucket 5.
- tooth adapter 4 That part of tooth adapter 4 which must be inserted into the cavity of tooth 3 is also known as "catch"; however, reference will only be made below to tooth adapter 4 without departing from the protection scope of the present invention.
- Figure 2 shows one advantageous embodiment of the present invention, wherein pin 10 has a substantially cylindrical outer surface; other shapes are however also conceivable, e.g. prismatic with a square, rectangular, triangular, polygonal, etc. cross-section.
- Expanding element 20 comprises a pair of balls on diametrically opposed sides relative to axis x-x of pin 10, which are adapted to move along a radial path while reversibly switching between the extracted and retracted positions .
- pin contains a different number of expanding elements 20 (or even just one) .
- expanding element 20 may, still in accordance with the present invention, have other non- limiting shapes, including: bar, parallelepiped, cylinder, ellipse, etc.
- expanding element 20 (which in the case illustrated herein is spherical in shape) is a movable element, preferably a sliding element, susceptible of moving between the extracted condition and the retracted condition.
- Retaining element 22 shown herein has a substantially annular shape, and includes a seat 24 formed on the face of retaining element 22 which is closer to pin 10.
- Said seat 24 is a recess so shaped as to easily receive expanding element 20, which in this case consists of a pair of balls.
- seat 24 advantageously has a continuous annular development along the entire retaining element 22, so as to be able to receive expanding element 20 irrespective of the angle between pin 10 and retaining element 22.
- device 1 comprises multiple seats 24 arranged on retaining element 22, each one intended for receiving one or more expanding elements 20.
- Retaining element 22 may have different shapes, preferably compliant with the shape of the cross-section of pin 10, such as: square, rectangular, triangular, polygonal, open section, "C" section, etc.
- device 1 is in the retracted position, in which expanding elements 20 (in this case, balls) are close to axis x-x and do not protrude past the outer surface of pin 10. Balls 20 are not in contact with retaining element 22, and therefore a relative movement (along the axis x-x) is possible between pin 10 and retaining element 22, which allows pin 10 to be extracted from apertures 12, 14 and tooth 3 to be disengaged from tooth adapter 4 of bucket 5.
- device 1 comprises at least one duct 26, formed in pin 10 and allowing the reversible movement of the at least one expanding element 20 between the extracted condition and the retracted condition.
- Figure 4 shows device 1 in the extracted position, in which balls 20 protrude at least partially past the outer surface of pin 10 for mechanically cooperating with retaining element 22 to prevent any relative movement between pin 10 and retaining element 22, so as to firmly engage tooth 3 with tooth adapter 4 of bucket 5.
- Device 1 further comprises an actuator 30 adapted to allow said at least one expanding element 20 to reversibly switch from the retracted position to the extracted position.
- actuator 30 is a threaded screw to be at least partially inserted into a hole 32 provided on the pin.
- a user will act upon screw 30, typically by means of a wrench, in order to bring said screw 30 closer to the at least one expanding element 20 until they come in contact with each other; at this point, the tip of screw 30 will push, as it goes forwards, expanding element 20 towards a position farther away from axis x-x, i.e. towards the extracted position, thus securing tooth 3 to bucket 5 and allowing the excavating machine to be normally used.
- tooth 3 needs to be replaced, the user will undo screw 30 to move the at least one expanding element 20 into the retracted condition, thus allowing removal of pin 10.
- screw 30 is coaxial to pin 10.
- actuator 30 may also move along an axis that does not coincide with axis x-x.
- actuator 30 is a threaded screw, it is also conceivable to use a self-locking element, or self-locking material, suitable for preventing the screw from loosing accidentally and causing expanding element 20 to move from the extracted position to the retracted position.
- actuator 30 can move said at least one expanding element 20 by means of a gear or a gear system.
- actuator 30 can move said at least one expanding element 20 by means of a lever or a lever system.
- retaining element 22 will be referred to below as a "ring”, without however limiting the scope of the invention.
- Figures 6 and 7 illustrate a second embodiment of the present invention, which comprises an elastic means 34 capable for bringing said at least one expanding element 20 towards one of the extracted position and the retracted position.
- elastic means 34 is a spring, such as a coil spring.
- Other per se known elastic means 34 may alternatively be used, such as, for example, a disk spring, or an elastically deformable element, such as a reed or a small bar, a rubber element, or chemical materials having an elastic behaviour.
- elastic means 34 is adapted to bring expanding element 20 towards the extracted position.
- the user After having inserted pin 10 through holes 12, 14 of tooth 3 and of tooth adapter 4, the user will associate the ring with pin 10; then, by operating actuator 30, the user will bring the expanding element into the extracted condition in order to mechanically secure the ring to pin 10, thereby preventing them from mutually sliding along axis x-x, hence securing tooth 3 to tooth adapter 4.
- elastic means 34 which will tend to hold expanding elements 20 in the extracted position, in order to place the ring into the correct position along axis x-x of pin 10 the user will have to slide the ring along pin 10 against the resistance opposed by elastic means 34, which will tend to hold expanding elements 20 in the extracted condition.
- expanding elements 20 protrude at least partially from the external side surface of pin 10, and therefore the ring will encounter an obstacle while sliding along pin 10.
- the presence of elastic means 34 prevents the risk that the ring might be incorrectly secured to pin 10, because it will be easy for the user to understand when pin 10 and the ring are in the proper mutual position, and then to operate actuator 30 in order to lock expanding elements 20 in the extracted condition, thus securing tooth 3 to tooth adapter 4.
- expanding elements 20 will, through the effect of elastic means 34, move away from axis x-x of pin 10, arranging themselves in the extracted condition in abutment with seat 24 of the ring; at this stage, a short vibration and a "clack" noise may be generated because of the sudden movement of expanding elements 20. The user can thus easily perceive that pin 10 and the ring have been properly engaged.
- elastic means 34 is positioned between two expanding elements 20, and exerts a repulsion force on such expanding elements 20 that tends to move them away from axis x-x into the extracted position.
- a first end (on the right in the drawing) of elastic means 34 is in contact with one expanding element 20, while a second end (on the left) of elastic means 34 is in contact with the other expanding element 20.
- Elastic means 34 is arranged in ducts 26.
- pin 10 may be equipped with one elastic means 34 for each expanding element 20.
- Elastic means 34 may be associated with an abutment portion of pin 10; thus, a first end of elastic means 34 is in contact with one expanding element 20, and a second end of elastic means 34 is associated with the abutment portion.
- actuator 30 in the absence of actuator 30 one can engage/disengage pin 10 and the ring by applying a force overcoming the force exerted by elastic means 34 to hold the expanding elements 20 in the extracted condition, thus allowing mutual sliding between pin 10 and the ring.
- actuator 30 will contribute to hold expanding means 20 more firmly in said extracted condition in contact with the ring, thus minimizing the risk that pin 10 and ring might accidentally come off.
- the outer surface of pin 10 has a shape that limits the sliding of the ring along axis x-x of the same pin 10.
- the outer surface of pin 10 has two different cross-sections along its axis x-x (the cross- sections are perpendicular to the axis x-x) .
- pin 10 includes a first portion 10a with a smaller cross- section and a second portion 10b with a larger cross- section.
- the two cross-sections are two circumferences having different diameters.
- Portion 10a of pin 10 that extends from a first end of the latter (the upper end in Figure 6) to expanding elements 20 has a smaller cross-section; the remaining portion 10b of pin 10 has a larger cross-section.
- the outer surface of pin 10 has a configuration that resembles two superimposed coaxial cylinders.
- device 1 may be so shaped as to be able to receive a tool or wrench, so that said device 1 can be held while an operator is acting upon actuator 30.
- actuator 30 is a screw
- on the side opposite to said screw there may be a housing adapted to receive a second tool (e.g. an Allen wrench), so that the necessary torque can be applied without device 1 turning within apertures 12, 14.
- a second tool e.g. an Allen wrench
- device 1 comprises a housing formed on pin 10 and shaped for receiving a tool or wrench. Housings are generally formed at the ends of pin 10, along the longitudinal axis x-x thereof. Device 1 illustrated in Figure 6 comprises a pair of housings: the first housing 40 is located at hole 32 that accommodates actuator 30 (upper part of the drawing) , and the second housing 42 is formed at the end of portion 10b of the pin (lower part of the drawing) .
- device 1 comprises a closing element 50, 52, e.g. a plug or the like, for closing the respective housing. This will avoid undesired entry of debris and dirt, ensuring better efficiency and a longer life of device 1.
- a closing element 50, 52 e.g. a plug or the like
- Closing element 50, 52 is removable, thus allowing the tools to be inserted into respective housing 40, 42.
- Closing element 50, 52 may be made of any material; preferably it is made of rubber or plastic.
- Closing element 50, 52 may have many different shapes, e.g. cylindrical, truncated cone, parallelepiped, etc.
