The following is a description of the embodiments of the present invention based on its overall structure.

[0030] Figure 1 It is a structural schematic diagram of the rake-type bucket provided by the utility model. Figure 2 This is a schematic diagram of the bottom structure provided by the utility model. Figure 5It is a schematic diagram of the internal structure of the rake type bucket provided by the utility model, and the rake type bucket includes: rake teeth 1, a shovel body 2, a driving mechanism 3, and a connecting rod mechanism 4. A protrusion 11 is formed on the side of the first end 15 of the rake tooth 1, and a slide groove 20 matching the protrusion 11 is formed on the inner side of the shovel body 2. The multiple rake teeth 1 are arranged horizontally and linearly, and the protrusion 11 is clamped on the slide groove 20.

[0031] Both ends of the driving mechanism 3 are respectively connected to the shovel body 2, the driving mechanism 3 passes through a plurality of rake teeth 1 inside the shovel body 2, and the output end of the driving mechanism 3 is connected to the leftmost rake tooth 1 among a plurality of horizontally linearly arranged rake teeth 1.

[0032] The first end of the connecting rod mechanism 4 is connected to the leftmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1, and the second end of the connecting rod mechanism 4 is connected to the shovel body 2 close to the rightmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1.

[0033] The driving mechanism 3 is used to drive the rake teeth 1 so that the rake teeth 1 can move horizontally, and the connecting rod mechanism 4 is used to control the distance between the rake teeth 1 when the rake teeth 1 move so that the rake teeth 1 can move at equal distances.

[0034] In the above-mentioned rake bucket, the rake teeth 1 in the rake bucket are made to have adjustable distances, and the driving mechanism 3 is used to drive the rake teeth 1 to move, while the connecting rod mechanism 4 is used to limit the moving distance between the rake teeth 1, so that the rake teeth 1 can move at equal distances when moving.

[0035] Figure 3 This is a schematic diagram of the structure of the shovel body provided by the utility model, see Figure 1 , Figure 3 and Figure 5 The shovel body 2 includes a shovel body 21 and fixed blocks 22 connected to both ends of the shovel body 21, side plates 23 are connected between the fixed blocks 22, the top of the fixed block 22 and the top of the side plate 23 are respectively connected to the shovel body 21, and the two side plates 23 are respectively arranged at both ends of the fixed block 22, so that a space for accommodating the first end of the rake tooth 1 is formed between the two side plates 23; wherein the slide groove 20 is opened on the side plate 23, a groove 210 is opened on the shovel body 21, and the connecting rod mechanism 4 is arranged in the groove 210.

[0036] Figure 4 This is a schematic diagram of the internal structure of the rake bucket provided by the utility model. Figure 3 , Figure 4 and Figure 5More specifically, the two fixing blocks 22 are connected to the two ends of the shovel body 21, and the two side plates 23 are respectively connected to the two ends of the fixing blocks 22, and the distance between the two side plates 23 is sufficient to accommodate the first end of the rake tooth 1. The top of the fixing block 22 and the top of the side plate 23 are in the same horizontal plane, and the top of the fixing block 22 and the top of the side plate 23 are connected to the shovel body 21 together. The inner sides of the two side plates 23 are provided with the sliding grooves 20, and the two sliding grooves 20 are in the same level. When the rake tooth 1 is driven to move, the protrusions 11 on the side surfaces of the first end of the rake tooth 1 can move on the sliding grooves 20. The arrangement of the sliding grooves 20 and the protrusions 11 can further support the rake tooth 1 on the shovel body 21.

[0037] At the same time, the top of the first end of the rake tooth 1 contacts the inner surface 211 of the shovel body 21. When the rake tooth 1 is grabbing or digging, the protrusion 11 is clamped on the side of the shovel body 21, and the top of the rake tooth 1 contacts the inner surface 211 of the shovel body 21, so that the rake tooth 1 is firmly stressed.

[0038] Specifically, a boom connecting plate 9 is connected to the shovel body 2 , and a through hole 90 is provided on the boom connecting plate 9 . The through hole 90 is used to connect the rake bucket to an excavator.

[0039] More specifically, the shovel body 21 is connected to two boom connecting plates 9, and the boom connecting plates 9 can connect the shovel body 2 to the digging arm of the excavator, thereby connecting the entire rake bucket to the excavator.

[0040] Specifically, in a more specific implementation scheme, the shovel body 21, the fixing block 22 and the side plate 23 are integrally arranged.

[0041] In a more specific embodiment, such as in this embodiment, the cross section of the shovel body 21 is trapezoidal, and in some other embodiments, the cross section of the shovel body 21 is triangular. This setting can be specifically set according to the boom connecting plate 9.

[0042] See also Figure 4 In a specific implementation scheme, the driving mechanism 3 includes a ball screw 31 and a ball nut 32, the ball nut 32 is connected to the leftmost rake tooth 1 among a plurality of horizontally linearly arranged rake teeth 1, the input end of the ball screw 31 is arranged outside the shovel body 2, and the ball screw 31 passes through the shovel body 2 and is connected to the ball nut 32, and then passes through the remaining rake teeth 1 in sequence.

[0043] See also Figure 4Specifically, the input end of the ball screw 31 is arranged outside the shovel body 2, and the ball screw 31 is rotated outside the shovel body 2, so that the ball nut 32 can move back and forth on the ball screw 31, thereby realizing the movement of the rake teeth 1.

[0044] See also Figure 4 Specifically, a first through hole 12 is provided on the leftmost rake tooth 1 among the plurality of horizontally linearly arranged rake teeth 1, in which the ball screw 32 is provided, and a second through hole 13 is provided on the remaining rake teeth 1, and the ball screw 31 is connected to the ball screw 32 and then passes through the second through holes 13 on the remaining rake teeth 1 in sequence. The leftmost rake tooth 1 among the plurality of horizontally linearly arranged rake teeth 1 moves under the drive of the ball screw 32, and at the same time, under the setting limit of the connecting rod mechanism 4, the rake tooth 1 without the ball screw 32 can also move, and the rake teeth 1 can also move at equal distances.

[0045] See also Figure 4 Specifically, the aperture of the second through hole 13 is larger than that of the first through hole 12. When the ball screw 31 rotates in the second through hole 13, it does not contact the inner surface of the second through hole 13 to prevent the ball screw 31 from scratching the inner surface of the second through hole 13, thereby avoiding damage to the ball screw 31.

[0046] Figure 6 This is a schematic diagram of the rake teeth of the rake bucket provided by the utility model when moving, see Figure 4 and Figure 6 In a specific implementation scheme, the connecting rod mechanism 4 includes a first connecting rod 41, multiple second connecting rods 42 and a third connecting rod 43, the first end of the first connecting rod 41 is connected to the leftmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1; every two of the second connecting rods 42 are fixedly connected to form a connecting rod assembly 420, and the multiple connecting rod assemblies 420 are rotatably connected to each other, and each connecting rod assembly 420 is rotatably connected to the rake tooth 1; the second end of the first connecting rod 41 is connected to the connecting rod assembly 420 on the leftmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1; the first end of the third connecting rod 43 is connected to the connecting rod assembly 420 on the rightmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1, and the second end of the third connecting rod 43 is connected to the shovel body 2.

[0047] Specifically, through the above-mentioned connecting rod mechanism 4, when the leftmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1 moves, the first connecting rod 41 will drive the connecting rod assembly 420 connected thereto to rotate. Since the connecting rod assemblies 420 drive each other and each second connecting rod 42 in the connecting rod assembly 420 has the same length, this connecting rod transmission can enable the distance between the rake teeth 1 to be set at equal distances when the rake teeth 1 move.

[0048] In a more specific embodiment, the connecting rod mechanism 4 cooperates with the ball screw 31 and the ball nut 32, and screws can be set on the side plate 23 according to actual application conditions. When the ball nut 32 is driven to move to a certain position and no longer moves, the rake teeth 1 are fixedly connected to the side plate 23 by screws, so that the rake teeth 1 cannot move. When the distances between the rake teeth 1 are consistent, the rake teeth 1 are fixed, so that the use of the rake teeth 1 is more stable. This method is set according to the specific use site and use requirements.

[0049] In a more specific implementation scheme, for example, when the distance between the rake teeth 1 is not convenient for on-site construction, after adopting the above-mentioned connecting rod mechanism 4 and the driving mechanism 3, the distance between the rake teeth 1 is adjusted to the required requirement, and then the rake teeth 1 are fixed to the shovel body 2 by screws. When the rake teeth 1 are used next time, the distance between the rake teeth 1 is adjusted again, and then the rake teeth 1 are fixed to the shovel body 2 by screws. This can solve the problem that the distance between the existing rake teeth 1 is fixed and cannot be flexibly used in various venues.

[0050] Specifically, the connection rod mechanism 4 described above needs to be set according to the actual situation of the rake teeth 1. For example, the lengths of the first connecting rod 41, the second connecting rods 42 and the third connecting rod 43 in the connection rod mechanism 4 can be set according to the actual situation.

[0051] See also Figure 4 The rake-type bucket also includes a first fixing rod 5, a first end of which passes through the leftmost rake tooth 1 among a plurality of horizontally linearly arranged rake teeth 1, and a second end of the first fixing rod 5 is connected to the shovel body 2.

[0052] Specifically, when the leftmost rake tooth 1 among the plurality of horizontally linearly arranged rake teeth 1 is moved to the leftmost side of the rake bucket, the leftmost rake tooth 1 is fixed to the shovel body 2 using the first fixing rod 5. When the leftmost rake tooth 1 moves to the right, it is released from the leftmost rake tooth 1 to facilitate the movement of the rake tooth 1.

[0053] See also Figure 4A connecting rod 6 is provided on the first end of the rake teeth 1, so that a plurality of the rake teeth 1 are sleeved on the connecting rod 6, and both ends of the connecting rod 6 are connected to the shovel body 2.

[0054] Specifically, the connecting rod 6 can support the multiple rake teeth 1 , and the multiple rake teeth 1 can move on the connecting rod 6 .

[0055] See also Figure 3 and Figure 4 Specifically, the first end of the connecting rod 6 is connected to the fixed block 22 on the left side of the shovel body 2 and passes through the fixed block 22. The first end of the connecting rod 6 is connected to the fixed block 22 on the right side of the shovel body 2, and the second end of the connecting rod 6 is provided with a thread, and a threaded hole is provided on the fixed block 22 on the right side of the shovel body 2. The second end of the connecting rod 6 is screwed into the threaded hole on the fixed block 22 on the right side of the shovel body 2.

[0056] See also Figure 4 and Figure 6 The second end of the rake tooth 1 is connected with a tooth portion 7, and the tooth portion 7 is provided with a cavity capable of accommodating the second end of the rake tooth 1. The tooth portion 7 is sleeved on the second end of the rake tooth 1 and is detachably connected to the second end of the rake tooth 1 through a connecting piece.

[0057] Specifically, the second end 14 of the rake tooth 1 is sleeved with a tooth portion 7, and the tooth portion 7 is provided to enable the rake bucket to be widely used, and at the same time, to protect the second end 14 of the rake tooth 1 to a certain extent. The tooth portion 7 is equivalent to increasing the width of the second end 14 of the rake tooth 1. For example, when the rake bucket is digging sand to loosen the sand, the tooth portion 7 is used to increase the contact area between the second end 14 of the rake tooth 1 and the sand. When the rake bucket is cleaning a river channel, due to garbage and weeds in the river channel, the second end 14 of the rake bucket needs to be sharp, and the tooth portion 7 is not needed at this time.

[0058] See also Figure 4 Specifically, a second fixing rod 8 is provided between the plurality of rake teeth 1 , and the second fixing rod 8 can make the rake teeth 1 more stable.

[0059] Next, combine Figure 1-Figure 6 The distance adjustment principle of the rake bucket in this embodiment is described in detail to enable those skilled in the art to better understand the present invention, as follows:

[0060] like Figure 4As shown, the input end 310 of the ball screw 31 is driven to rotate the ball screw 31 counterclockwise. At this time, the ball nut 32 on the ball screw 31 moves to the right on the ball screw 31, driving the leftmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1, that is, the rake tooth 1 fixedly connected to the ball nut 32, to move to the right.

[0061] like Figure 6 As shown, when the rake teeth 1 move to the right, the first connecting rod 41 is rotated by the thrust, thereby driving the connecting rod assembly 420 to rotate. Since the lengths of the second connecting rods 42 in the connecting rod assembly 420 are set to be consistent, the distances between the rake teeth 1 can be consistent when the rake teeth 1 move. At the same time, the third connecting rod 43 located on the right side will rotate under the push of the connecting rod assembly 420.

[0062] When the rake teeth 1 move to Figure 6 In the state shown, the input end 310 of the ball screw 31 is driven to rotate the ball screw 31 counterclockwise. At this time, the ball screw nut 32 on the ball screw 31 moves leftward on the ball screw 31, driving the leftmost rake tooth 1 among the multiple horizontally linearly arranged rake teeth 1, that is, the rake tooth 1 fixedly connected to the ball screw nut 32, to move leftward. The first connecting rod 41 is subjected to tension, and at the same time, the connecting rod assembly 420 and the third connecting rod 43 are also subjected to tension, and finally the rake tooth 1 can be moved to the state shown in FIG. Figure 4 Status shown.

[0063] In the above-mentioned explanation of the distance adjustment principle of the rake bucket, the ball screw 31 can be driven to stop at any position according to the demand, and the setting of the connecting rod mechanism 4 can make the distance between the rake teeth 1 the same. In order to make the rake teeth 1 more stable during excavation, the rake teeth 1 can be fixed to the side plate 23. This setting is set by the operator according to the actual application site.

[0064] In the above-mentioned explanation of the distance adjustment principle of the rake bucket, when the rake teeth 1 move, the protrusions 11 on the rake teeth 1 can move in the slide grooves 20 on the side plates 23, and the rake teeth 1 move on the connecting rods 6. The slide grooves 20 and the connecting rods 6 can support the rake teeth 1.

[0065] In summary, the rake-type bucket provided by the utility model can overcome the defect that the rake teeth of the prior art rake-type bucket cannot adjust the distance through the driving mechanism 3 and the connecting rod mechanism 4, and can adjust the distance of the rake teeth. At the same time, the rake teeth can be removed from the shovel body, which is convenient for the later repair and maintenance of the rake teeth.

[0066] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of explanation and illustration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
