Description

Technical Field

[0001] The present invention relates to an excavator, and particularly to a bucket of an excavator. Background Art

[0002] The bucket of an excavator is a core component for the excavator to work, and it can be used for excavating, loading and transporting materials. Among them, the drum bucket is a special bucket of an excavator. In addition to the common functions of an ordinary bucket, it can also screen materials through the rotational movement of its drum, and can be more flexible in adapting to different constructions.

[0003] The existing drum buckets generally have a screen cylinder with mesh holes designed to play a screening role. Although it has a screening function that a conventional bucket does not have, it is at a disadvantage in the loading and transporting functions of finer materials, especially fluid materials. Therefore, it is necessary to design an excavator bucket that not only has the screening function of a drum bucket but also can better adapt to the excavation, loading and transporting of finer materials. Summary of the Invention

[0004] The present invention provides a bucket of an excavator in view of the problems existing in the bucket of an excavator in the prior art.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A bucket of an excavator includes a hopper part. The hopper part includes an outer drum and an inner drum that forms a rotational limit with the outer drum. Both the inner drum and the outer drum are cylindrical bodies with mesh holes. The outer drum can axially move relative to the inner drum to a closed state of the hopper part and a screening state of the hopper part. When the outer drum is in the closed state of the hopper part, the mesh holes on the inner drum are misaligned with the mesh holes on the outer drum. When the outer drum is in the screening state of the hopper part, the mesh holes on the inner drum are opposite to the mesh holes on the outer drum.

[0006] Preferably, it further includes a bucket fixing frame. The hopper part is installed on the bucket fixing frame. A screening motor for driving the rotation of the hopper part and a push-pull electromagnet for driving the axial movement of the outer drum relative to the inner drum are installed on the bucket fixing frame. The screening motor is electrically connected to the push-pull electromagnet. When the screening motor is started, the push-pull electromagnet is energized to move the outer drum to the screening state of the hopper part. When the screening motor is powered off, the push-pull electromagnet is powered off to move the outer drum to the closed state of the hopper part. The cooperation of the screening motor and the push-pull electromagnet can realize the closed state and the screening state of the bucket.

[0007] Preferably, a sliding block is provided at the end of the telescopic rod of the push-pull electromagnet, and an annular chute for the sliding block to slide is provided on the end face of the outer drum facing the push-pull electromagnet.

[0008] Preferably, the inner drum includes an inner barrel wall. At the end of the inner barrel wall facing the screening motor, there is a barrel end plate connected to the motor shaft of the screening motor. At the end of the inner barrel wall away from the screening motor, there is a first outer ring disposed on the outer surface of the inner barrel wall. The outer drum includes an outer barrel wall. At the end of the outer barrel wall facing the push-pull electromagnet, there is an inner ring disposed on the inner surface of the outer barrel wall. The annular chute is disposed on the end face of the inner ring; It further includes a second outer ring with an interference fit between its inner surface and the outer surface of the outer barrel wall. The second outer ring is disposed at the end of the outer barrel wall facing the push-pull electromagnet. The first outer ring and the second outer ring are connected by multiple connecting rods. The second outer ring is rotatably connected to the bucket fixing frame. The settings of the first outer ring and the second outer ring can increase the structural stability of the screening cylinder and also increase the connection stability between it and the bucket fixing frame.

[0009] Preferably, on the end face of the first outer ring, there is an annular insertion hole. Inside the annular insertion hole, multiple insertion rods are evenly spaced. The end of the outer barrel wall away from the push-pull electromagnet can be inserted into the annular insertion hole and is axially slidably engaged with the annular insertion hole. On the end face of the outer barrel wall away from the push-pull electromagnet, there are rotation limiting holes for the insertion rods to insert. The cooperation between the insertion rods and the rotation limiting holes can achieve the rotation limit between the inner cylinder body and the outer cylinder body.

[0010] Preferably, on the inner side wall of the inner ring, there is a limiting chute. The limiting chute is circular and coaxially arranged with the outer drum. On the sliding block, there is a limiting slider that can slide along the limiting chute. One end of the limiting slider is connected to the sliding block, and the other end is bent into a U-shaped block with its end caught in the limiting chute. When the limiting slider is caught in the limiting chute, one side wall of the sliding block is slidably engaged with one inner side wall of the annular chute. The settings of the limiting chute and the limiting slider can achieve the sliding guidance of the sliding block.

[0011] Preferably, it further includes a vibrating material mechanism disposed inside the side wall of the outer drum. On the end face of the outer drum facing the push-pull electromagnet, there is a vibration blind hole with its axis parallel to the axis of the outer drum. The vibrating material mechanism includes a vibration block disposed in the vibration blind hole and capable of intermittently knocking on the bottom wall of the vibration blind hole; the vibrating material mechanism further includes a vibration block driving mechanism for driving the vibration block to move. The vibration block driving mechanism includes a vibration rod connected to the vibration block, a return spring sleeved on the vibration rod, and a driving block disposed at the end of the vibration rod away from the vibration block. The driving block can drive the vibration rod to move axially along the vibration blind hole under the action of the sliding block. The setting of the vibrating material mechanism can further improve the working performance of the excavator bucket and effectively provide the material screening effect.

[0012] Preferably, a first inclined surface is provided on the sliding block, and a second inclined surface cooperating with the first inclined surface is provided on the driving block. During the sliding of the sliding block in the annular chute, the first inclined surface can act on the second inclined surface to move the driving block away from the bottom wall of the vibration blind hole. The cooperation of the two inclined surfaces enables the conversion of circular motion into the axial motion of the driving block along the axis of the vibration blind hole during their relative motion.

[0013] Preferably, it further includes a tooth-digging part. The tooth-digging part includes a plurality of tooth-digging teeth arranged at intervals in the width direction of the tooth-digging part. A leveling plate is detachably connected to the tooth-digging teeth. Both ends of the leveling plate extend to both ends in the width direction of the tooth-digging part. The end surface of the leveling plate facing away from the hopper part is a plane, and this plane constitutes the leveling surface of the digging bucket. The setting of the leveling plate enables the digging bucket to have better spreading and leveling functions, and can better adapt to the loading and transfer of finer materials.

[0014] Preferably, it further includes a leveling plate connecting piece arranged between the tooth-digging teeth and the leveling plate. The leveling plate connecting piece includes tooth-digging sleeves corresponding to the tooth-digging teeth one by one and sleeved on the tooth-digging teeth. A splicing plate is provided on each tooth-digging sleeve, and the leveling plate is formed by splicing the splicing plates. It also includes a fixing rod passing through all the splicing plates, and both ends of the fixing rod are installed on the side walls of the tooth-digging part through bolts. The leveling plate is detachably connected to the tooth-digging teeth. When spreading is not required, it can be removed without affecting the digging function of the tooth-digging teeth themselves.

[0015] Due to the adoption of the above technical solutions, the present invention has remarkable technical effects: Through the structural design of the digging bucket of the excavator, the present invention enables it to have both the screening function of a drum-type digging bucket and better adapt to the excavation, loading, and transfer of finer materials.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Embodiment 1 An excavator bucket, as Figures 1 - 14 shown, includes a bucket fixing frame 2, a hopper part 1 installed on the bucket fixing frame 2, and a tooth - digging part 3. The hopper part 1 includes an outer drum 101 and an inner drum 102 that forms a rotational limit with the outer drum 101. Both the inner drum 102 and the outer drum 101 are cylindrical bodies with mesh holes. The outer drum 101 can axially move relative to the inner drum 102 to a closed state of the hopper part and a screening state of the hopper part. When the outer drum 101 is in the closed state of the hopper part, the mesh holes on the inner drum 102 are misaligned with the mesh holes on the outer drum 101. When the outer drum 101 is in the screening state of the hopper part, the mesh holes on the inner drum 102 are opposite to the mesh holes on the outer drum 101.

[0032] Among them, a screening motor 201 for driving the hopper part 1 to rotate and a push-pull electromagnet 202 for driving the outer drum 101 to move axially relative to the inner drum 102 are installed on the bucket fixing frame 2. The screening motor 201 is electrically connected to the push-pull electromagnet 202. When the screening motor 201 starts, the push-pull electromagnet 202 is energized so that the outer drum 101 moves to the screening state of the hopper part. When the screening motor 201 is powered off, the push-pull electromagnet 202 is powered off so that the outer drum 101 moves to the closed state of the hopper part. The push-pull electromagnet 202 in this embodiment adopts a conventional telescopic electromagnet with a waterproof function that can be purchased on the market.

[0033] The excavator bucket proposed in this embodiment not only has the function of screening with a drum-type bucket, but also can better adapt to the excavation, loading and transportation of finer materials. The specific application process is as follows: During the excavation process, the screening motor 201 is in the powered-off state. At this time, the push-pull electromagnet 202 is also in the powered-off state. The telescopic rod of the powered-off push-pull electromagnet 202 will extend under the action of the spring thereon, and then push the outer cylinder to move axially relative to the inner cylinder, so that the sieve holes on the outer cylinder are misaligned with the sieve holes on the inner cylinder, so that the hopper part 1 is in the closed state. In this state, the excavation, loading and transportation of finer materials or even fluid materials (such as silt) can be realized (the materials flowing out through the pores or the gaps between the cylinders can be ignored).

[0034] During the screening process, both the screening motor 201 and the push-pull electromagnet 202 are in the powered-on state. The push-pull electromagnet 202 can be operated first to pull the outer cylinder axially back so that the sieve holes on the outer cylinder coincide with the sieve holes on the inner cylinder. At this time, the hopper part 1 can form a screening cylinder. Then the screening motor 201 operates to quickly rotate the screening cylinder, so that the materials that can pass through the sieve holes in it are separated from the screening cylinder under the action of centrifugal force, playing a screening function. When designing, the aperture diameters of the sieve holes on the inner and outer cylinders can be designed to be the same to ensure the screening effect.

[0035] In this embodiment, a sliding block 203 is provided at the end of the telescopic rod of the push-pull electromagnet 202, and an annular chute 204 for the sliding block 203 to slide is provided on the end face of the outer drum 101 facing the push-pull electromagnet 202.

[0036] Among them, the inner drum 102 includes an inner cylinder wall 103. A cylinder end plate 104 connected to the motor shaft of the screening motor 201 is provided at the end of the inner cylinder wall 103 facing the screening motor 201. A first outer ring 105 is provided on the outer surface of the inner cylinder wall 103 at the end of the inner cylinder wall 103 far from the screening motor 201. The outer drum 101 includes an outer cylinder wall 106. An inner ring 107 is provided on the inner surface of the outer cylinder wall 106 at the end of the outer cylinder wall 106 facing the push-pull electromagnet 202. The annular chute 204 is provided on the end face of the inner ring 107; It further includes a second outer ring 108 with an inner surface in clearance fit with the outer surface of the outer barrel wall 106. The second outer ring 108 is arranged at the end of the outer barrel wall 106 facing the push-pull electromagnet 202. A plurality of connecting rods 109 are connected between the first outer ring 105 and the second outer ring 108. The second outer ring 108 is rotatably connected to the bucket fixing frame 2.

[0037] An annular insertion hole 110 is provided on the end face of the first outer ring 105. A plurality of insertion rods 111 are evenly spaced in the annular insertion hole 110. The end of the outer barrel wall 106 away from the push-pull electromagnet 202 can be inserted into the annular insertion hole 110 and is in axial sliding fit with the annular insertion hole 110. A rotation limiting hole 112 for the insertion rod 111 to insert is provided on the end face of the outer barrel wall 106 away from the push-pull electromagnet 202.

[0038] When the insertion rod 111 is inserted into the rotation limiting hole 112, the end of the outer barrel wall 106 is inserted into the annular insertion hole 110 and the two form an axial sliding fit. Then the push-pull electromagnet 202 can pull the outer cylinder to axially slide on the outer surface of the inner cylinder. When the outer cylinder moves to two states, its end is always inserted into the annular insertion hole 110, and the insertion rod 111 and the rotation limiting hole 112 are always relative and always in a non-detaching state. Then it is ensured that a rotation limit can be formed between the inner drum 102 and the outer drum 101, and the outer cylinder can be driven to rotate synchronously when the inner cylinder rotates.

[0039] In addition, the setting of the first outer ring 105 and the second outer ring 108 can play a guiding and limiting role on the outside of the outer cylinder to ensure the stability of the overall structure of the inner and outer drums 101 during movement. And the first outer ring 105 and the second outer ring 108 also form a support ring for the entire bucket part. Compared with directly rotatably connecting the end of the outer cylinder to the bucket fixing frame 2, this kind of connection through the support ring has stronger structural stability and structural strength. A bearing can be set on its outer surface during the connection process to enable it to be rotatably connected to the bucket fixing frame 2 better.

[0040] In addition, a limiting sliding groove 113 is provided on the inner side wall of the inner ring 107. The limiting sliding groove 113 is circular and coaxially arranged with the outer drum 101. A limiting sliding block 114 capable of sliding along the limiting sliding groove 113 is constructed on the sliding block 203. One end of the limiting sliding block 114 is connected to the sliding block 203, and the other end is bent into a U-shaped block with an end portion clamped into the limiting sliding groove 113. When the limiting sliding block 114 is clamped into the limiting sliding groove 113, one side wall of the sliding block 203 slides in cooperation with one inner side wall of the annular sliding groove 204.

[0041] The provision of the limit sliding groove 113 and the limit sliding block 114 can limit the sliding block 203 within the annular sliding groove 204, enabling it to always fit against one of the inner sidewalls of the annular sliding groove 204, thereby guiding the sliding of the sliding block 203 within the annular sliding groove 204 and further ensuring that the sliding block 203 can better cooperate with the driving block 120 which is also within the annular sliding groove 204.

[0042] To further improve the working performance of the excavator bucket, a vibrating material mechanism 115 is also included and is disposed within the sidewall of the outer drum 101. An axial vibration blind hole 116 parallel to the axial direction of the outer drum 101 is provided on the end face of the outer drum 101 facing the push-pull electromagnet 202. The vibrating material mechanism 115 includes a vibrating block 117 disposed within the vibration blind hole 116 and capable of intermittently knocking on the bottom wall of the vibration blind hole 116; the vibrating material mechanism 115 further includes a vibrating block driving mechanism for driving the movement of the vibrating block 117. The vibrating block driving mechanism includes a vibrating rod 118 connected to the vibrating block 117, a return spring 119 sleeved on the vibrating rod 118, and a driving block 120 disposed at the end of the vibrating rod 118 away from the vibrating block 117. The driving block 120 can drive the vibrating rod 118 to move along the axial direction of the vibration blind hole 116 under the action of the sliding block 203.

[0043] Among them, a first inclined surface 121 is provided on the sliding block 203, and a second inclined surface 122 cooperating with the first inclined surface 121 is provided on the driving block 120. During the sliding process of the sliding block 203 within the annular sliding groove 204, the first inclined surface 121 can act on the second inclined surface 122 to cause the driving block 120 to move away from the bottom wall of the vibration blind hole 116.

[0044] During the screening process, some materials may get stuck at the sieve holes or the gaps between the inner and outer cylinders. Therefore, the vibrating material mechanism 115 is designed. When the screening cylinder rotates, the driving block 120 will rotate with the outer cylinder. When it rotates to a position relative to the sliding block 203, the first inclined surface 121 on the sliding block 203 will act on the second inclined surface 122 on the driving block 120, causing the driving block 120 to move away from the bottom wall of the vibration blind hole 116. At this time, the return spring 119 on the vibrating rod 118 stores energy. Then, the driving block 120 continues to move relative to the sliding block 203, causing the first inclined surface 121 and the second inclined surface 122 to disengage. At this time, the return spring 119 can cause the vibrating block 117 to knock on the bottom wall of the vibration blind hole 116, so that the entire screening cylinder vibrates to enhance the screening effect.

[0045] Multiple such vibrating mechanisms can be provided and evenly spaced around the outer cylinder, so that during the rotation of the outer cylinder, intermittent multiple knockings on the bottom wall of the vibration blind hole 116 can be achieved.

[0046] In this embodiment, a leveling and spreading function for the digging bucket is further added. The digging tooth part 3 includes a plurality of digging teeth 301 arranged at intervals in the width direction of the digging tooth part 3. A leveling plate 302 is detachably connected to the digging teeth 301. Both ends of the leveling plate 302 extend to both ends in the width direction of the digging tooth part 3. The end face of the leveling plate 302 facing away from the hopper part 1 is a plane, and this plane constitutes the leveling surface of the digging bucket. It further includes a leveling plate connecting member arranged between the digging teeth 301 and the leveling plate 302. The leveling plate connecting member includes digging tooth sleeves 303 corresponding to the digging teeth 301 one by one and sleeved on the digging teeth 301. A splicing plate 304 is provided on each digging tooth sleeve 303. The leveling plate 302 is composed of the splicing plates 304. It further includes a fixing rod 305 passing through all the splicing plates 304. Both ends of the fixing rod 305 are installed on the two side walls of the digging tooth part 3 by bolts.

[0047] The setting of the leveling plate 302 makes up for the fact that the conventional digging teeth 301 of the digging bucket are arranged at intervals and cannot perform a better spreading function for the material, and can better adapt to the loading and transportation of finer materials. The leveling plate 302 is detachably connected to the digging teeth 301. When spreading is not required, it can be removed without affecting the digging function of the digging teeth 301 themselves.

[0048] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided by the present application to obtain other embodiments, and these embodiments do not exceed the protection scope of the present application.

[0049] In summary, the above are only the preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
