Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to buckets and engineering machinery. Background Technology

[0002] Buckets on construction machinery (such as skid steer loaders) are becoming increasingly multifunctional, capable of performing various operations such as shoveling, pushing, scraping, and clamping. However, buckets in these technologies still suffer from poor pushing performance and low operational efficiency during operation. Utility Model Content

[0003] In view of this, the present invention provides a bucket and engineering machinery to solve the problems of poor pushing effect and low operation efficiency of the bucket during operation.

[0004] In a first aspect, this utility model provides a bucket, comprising: a rear bucket; a front bucket rotatably connected to the rear bucket, such that the front bucket and the rear bucket can rotate relative to each other to an open state and a closed state; a front bucket blade plate disposed at the front end of the front bucket, the front bucket blade plate being parallel to the bottom wall of the front bucket; and a rear bucket blade plate disposed at the front end of the rear bucket, wherein in the closed state, the rear bucket blade plate is inclined relative to the front bucket blade plate, and along the front-rear direction, the end of the rear bucket blade plate away from the rear bucket is lower than the end near the rear bucket and lower than the front bucket blade plate.

[0005] Beneficial effects: The rear bucket blade is inclined relative to the front bucket blade, so the force acting on the material can be decomposed into two directions: a vertical downward component and a horizontal forward component. The horizontal forward component "presses" and "prys up" the material, destroying its original structure, thus enabling the rear bucket blade to have a pushing function. The end of the rear bucket blade away from the rear bucket is lower than the front bucket blade, which allows for secondary pushing, shoveling, and scraping of the material remaining on the ground after the front bucket blade has pushed, resulting in more thorough cleaning and efficient operation.

[0006] In some embodiments, the included angle between the rear bucket blade and the front bucket blade is an acute angle.

[0007] Beneficial effects: This design further enhances the pushing function of the rear bucket blade, resulting in more thorough cleaning and efficient operation.

[0008] In some embodiments, the rear bucket blade is detachably connected to the rear bucket.

[0009] Beneficial effects: Facilitates replacement and maintenance, and extends the service life of the bucket.

[0010] In some embodiments, the front bucket blade is detachably connected to the front bucket.

[0012] In some embodiments, the bucket further includes: a hydraulic device, including a hydraulic cylinder and a hydraulic pipeline, wherein the telescopic end of the hydraulic cylinder is rotatably connected to the front bucket and the fixed end of the hydraulic cylinder is rotatably connected to the rear bucket, for driving the front bucket to rotate relative to the rear bucket; one end of the hydraulic pipeline is connected to the hydraulic cylinder and the other end is connected to an oil pumping device.

[0013] Beneficial effects: Hydraulic cylinder drive enables precise control of the bucket and provides greater thrust, improving work efficiency.

[0014] In some embodiments, the bucket further includes a bucket mounting plate fixed to the rear bucket, wherein the bucket is mounted on the main body of the construction machinery via the bucket mounting plate, and wherein the hydraulic lines do not overlap with the bucket mounting plate in the front-rear direction.

[0015] Beneficial effects: Compared to methods where hydraulic lines are located between the bucket mounting plate and the rear bucket, this design is more compact, increasing bucket capacity and improving operational efficiency. The bucket mounting plate can be a universal type with slotted hole interfaces, offering high versatility.

[0016] In some embodiments, the rear bucket includes a rear wall, the rear wall including a rear wall body and a rear bucket reinforcing plate connected to the upper edge of the rear wall body, the rear bucket reinforcing plate being bent toward the rear of the rear wall relative to the rear wall body; the hydraulic lines are fixed to the rear bucket reinforcing plate and are at least partially hidden below the rear bucket reinforcing plate.

[0017] Beneficial effects: The rear bucket reinforcement plate increases the strength of the rear bucket, and the rear bucket reinforcement plate bends backward relative to the rear wall body. The hydraulic lines are at least partially hidden under the rear bucket reinforcement plate, which can prevent the hydraulic lines from being damaged by falling materials during operation. It can also play a good protective role for the hydraulic lines and improve the reliability of operation.

[0018] In some embodiments, the front bucket includes two front bucket sidewalls opposite each other in the left-right direction, and the front bucket bottom wall and the two front bucket sidewalls form a front bucket receiving cavity; the rear bucket includes a rear bucket bottom wall and two rear bucket sidewalls opposite each other in the left-right direction, and the rear bucket bottom wall, the rear wall, and the two rear bucket sidewalls form a rear bucket receiving cavity; the two front bucket sidewalls and the two rear bucket sidewalls are rotatably connected by a first pin; two hydraulic cylinders are provided, the driving ends of the two hydraulic cylinders are rotatably connected to the two front bucket sidewalls by a second pin, and the fixed ends of the two hydraulic cylinders are rotatably connected to the two rear bucket sidewalls by a third pin, wherein the second pin is located above the third pin.

[0019] Beneficial effect: The front bucket is rotated synchronously by two hydraulic cylinders, which improves the stability of the bucket during operation.

[0020] In some embodiments, the front bucket further includes a front bucket reinforcing plate, which connects the front bucket sidewall and the front bucket bottom wall.

[0021] Beneficial effects: The front bucket reinforcement plate can improve the strength and stability of the front bucket.

[0022] In some embodiments, the rear side of the front bucket sidewall and the front side of the rear bucket sidewall are both provided with a serrated structure.

[0023] Beneficial effects: The serrated structure can improve the stability of material gripping when the front and rear buckets are closed.

[0024] Secondly, this utility model also provides an engineering machine, including: a mechanical body; and a bucket as described in any embodiment of the first aspect above, wherein the bucket is fixed to the mechanical body by a bucket mounting plate.

[0025] Beneficial effects: Since construction machinery includes the bucket mentioned in the first aspect above, construction machinery has the same beneficial effects as the bucket, which will not be elaborated here. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Buckets on construction machinery (such as skid steer loaders) are becoming increasingly multifunctional, capable of performing various operations such as shoveling, pushing, scraping, and clamping. However, buckets in these technologies often suffer from incomplete shoveling during operation, resulting in significant material residue on the ground that requires manual cleanup and leads to low operational efficiency. Research has revealed that because the rear bucket blade is parallel to the front bucket blade, the rear bucket blade provides almost no secondary shoveling effect after the front bucket blade has already pushed away material, resulting in a large amount of residual material on the ground.

[0031] To address this, the rear bucket blade is tilted relative to the front bucket blade and positioned lower than the front bucket blade, creating a certain angle between the rear bucket blade and the ground. This allows for a secondary push of the material remaining on the ground after the front bucket blade has pushed it, resulting in more thorough cleaning and efficient operation.

[0032] The following is combined Figures 1 to 3 The embodiments of this utility model will be described below.

[0033] According to an embodiment of the present invention, in a first aspect, a bucket is provided, including a rear bucket 10, a front bucket 20, a front bucket cutting edge 30, and a rear bucket cutting edge 40. The front bucket 20 and the rear bucket 10 are rotatably connected, allowing the front bucket 20 and the rear bucket 10 to rotate relative to each other to an open state and a closed state. The front bucket cutting edge 30 is disposed at the front end of the front bucket 20, and the front bucket cutting edge 30 is parallel to the front bucket bottom wall 21 of the front bucket 20. The rear bucket cutting edge 40 is disposed at the front end of the rear bucket 10. In the closed state, the rear bucket cutting edge 40 is inclined relative to the front bucket cutting edge 30, and along the front-rear direction X, the end of the rear bucket cutting edge 40 away from the rear bucket 10 is lower than the end near the rear bucket 10 and lower than the front bucket cutting edge 30.

[0034] The bucket can be installed on construction machinery, which can be a loader, such as a skid steer loader.

[0035] The front bucket 20 is located in front of the rear bucket 10, and the two are rotatably connected. When the front bucket 20 rotates away from the rear bucket 10, the front bucket 20 and the rear bucket 10 open. When the front bucket 20 rotates closer to the rear bucket 10, the front bucket 20 and the rear bucket 10 close, so as to realize different forms of operation such as shoveling, pushing, scraping, clamping, loading and unloading.

[0036] The front bucket 20 and the rear bucket 10 can be rotatably connected by a pin, with the front bucket 20 rotating relative to the rear bucket 10 around the pin.

[0037] In this embodiment, the forward / backward direction X refers to the direction of travel of the construction machinery, such as forward or backward. The left / right direction Y can be the width direction of the construction machinery. The up / down direction Z can be the height direction of the construction machinery.

[0038] The front bucket blade 30 is fixed to the front end of the front bucket 20. The front bucket blade 30 can be detachable or non-detachable. In this embodiment, the front bucket blade 30 is preferably detachable.

[0039] The front bucket blade 30 is parallel to the front bucket bottom wall 21 of the front bucket 20. The front bucket bottom wall 21 is the wall of the front bucket 20 used to carry materials. When the front bucket 20 and the rear bucket 10 are in the closed state, both the front bucket blade 30 and the front bucket bottom wall 21 can be parallel to the horizontal plane.

[0040] The rear bucket blade 40 is disposed at the front end of the rear bucket 10. The rear bucket blade 40 can be detachable or non-detachable. In this embodiment, the rear bucket blade 40 is preferably detachable.

[0041] With the front bucket 20 and rear bucket 10 in the closed state, the rear bucket blade 40 is inclined relative to the front bucket blade 30, meaning the rear bucket blade 40 is not parallel to the front bucket blade 30. Along the front-rear direction X, the end of the rear bucket blade 40 furthest from the rear bucket 10 is the front end, which is also the end with the cutting edge, and the end of the rear bucket blade 40 closest to the rear bucket 10 is the rear end, which is also the end connecting to the rear bucket 10. In other words, the rear bucket blade 40 is tilted forward, with the cutting edge lower than the connection point, and the rear bucket blade 40 is inclined relative to the horizontal plane.

[0042] The rear bucket blade 40 is inclined relative to the front bucket blade 30. The force acting on the material can be decomposed into two directions: a vertically downward component and a horizontally forward component. The horizontally forward component "presses" and "prys up" the material, destroying its original structure, thus enabling the rear bucket blade 40 to have a pushing function. The end of the rear bucket blade 40 that is away from the rear bucket 10 is lower than the front bucket blade 30, which can perform secondary pushing, shoveling, and scraping operations on the material remaining on the ground after the front bucket blade pushes, resulting in more thorough cleaning and efficient operation.

[0043] In some embodiments, the included angle α between the rear bucket blade 40 and the front bucket blade 30 is an acute angle.

[0044] For example, α can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 85°, etc. Preferably, α is 30°~60°.

[0045] This design further enhances the pushing function of the rear bucket shovel blade 40, resulting in more thorough cleaning and efficient operation.

[0046] In some embodiments, the rear bucket blade 40 is detachably connected to the rear bucket 10, facilitating replacement and maintenance and extending the service life of the bucket.

[0047] The rear bucket blade 40 can be detachably connected to the rear bucket 10 using fasteners such as bolts and screws.

[0048] In some embodiments, the front bucket blade 30 is detachably connected to the front bucket 20, facilitating replacement and maintenance and extending the service life of the bucket.

[0049] The front bucket blade 30 can be detachably connected to the front bucket 20 using fasteners such as bolts and screws.

[0050] In some embodiments, the bucket further includes a hydraulic device, which includes a hydraulic cylinder 51 and a hydraulic line 52. The telescopic end of the hydraulic cylinder 51 is rotatably connected to the front bucket 20, and the fixed end of the hydraulic cylinder 51 is rotatably connected to the rear bucket 10, for driving the front bucket 20 to rotate relative to the rear bucket 10. One end of the hydraulic line 52 is connected to the hydraulic cylinder 51, and the other end is connected to a pumping device. The hydraulic line 52 may include an inlet pipe and a return pipe, and the hydraulic cylinder 51 is connected to the pumping device through the inlet pipe and the return pipe. The hydraulic cylinder 51 may be an oil cylinder.

[0051] The hydraulic cylinder 51 drive enables precise control of the bucket and provides greater thrust, improving operational efficiency.

[0052] In some embodiments, the bucket also includes a bucket mounting plate 60, which is fixed to the rear bucket 10. The bucket is mounted on the main body of the construction machinery via the bucket mounting plate 60, wherein the hydraulic line 52 does not overlap with the bucket mounting plate 60 along the front-rear direction X.

[0053] The hydraulic line 52 not overlapping with the bucket mounting plate 60 means that the hydraulic line 52 is not located between the bucket mounting plate 60 and the rear bucket 10; for example, it can bypass the bucket mounting plate 60. Compared to a configuration where the hydraulic line 52 is located between the bucket mounting plate 60 and the rear bucket 10, this design is more compact, increasing the bucket's capacity and improving operational efficiency. The bucket mounting plate 60 can be a universal mounting plate with oblong hole interfaces, offering high versatility.

[0054] In some embodiments, the rear bucket 10 includes a rear wall 11, which includes a rear wall body and a rear bucket reinforcing plate 12 connected to the upper edge of the rear wall body. The rear bucket reinforcing plate 12 is bent rearward relative to the rear wall body. A hydraulic line 52 is fixed to the rear bucket reinforcing plate 12 and is at least partially hidden below the rear bucket reinforcing plate 12.

[0055] The rear bucket reinforcement plate 12 enhances the strength of the rear bucket 10, and the rear bucket reinforcement plate 12 bends backward relative to the rear wall body. The hydraulic pipeline 52 is at least partially hidden under the rear bucket reinforcement plate 12, so that the rear bucket reinforcement plate 12 can prevent materials falling during operation from damaging the hydraulic pipeline 52, and can also play a good protective role for the hydraulic pipeline 52, thereby improving the reliability of operation.

[0056] In some embodiments, the front bucket 20 includes two front bucket sidewalls 22 facing each other in the left-right direction Y, and the front bucket bottom wall 21 and the two front bucket sidewalls 22 form a front bucket receiving cavity. The rear bucket 10 includes a rear bucket bottom wall 13 and two rear bucket sidewalls 14 facing each other in the left-right direction Y, and the rear bucket bottom wall 13, rear wall 11 and the two rear bucket sidewalls 14 form a rear bucket receiving cavity. The two front bucket sidewalls 22 and the two rear bucket sidewalls 14 are rotatably connected by a first pin 71. Two hydraulic cylinders 51 are provided. The driving ends of the two hydraulic cylinders 51 are rotatably connected to the two front bucket sidewalls 22 by a second pin 72, and the fixed ends of the two hydraulic cylinders 51 are rotatably connected to the two rear bucket sidewalls 14 by a third pin 73, with the second pin 72 located above the third pin 73.

[0057] Two hydraulic cylinders 51 synchronously drive the front bucket 20 to rotate, improving the stability of the bucket during operation.

[0058] In some embodiments, the front bucket 20 further includes a front bucket reinforcing plate 23, which connects the front bucket sidewall 22 and the front bucket bottom wall 21, thereby improving the strength and stability of the front bucket 20.

[0059] The front bucket reinforcing plate 23 can be made of high-strength steel. The front bucket reinforcing plate 23 may include two plates, which are connected, and each plate connects the front bucket side wall 22 and the front bucket bottom wall 21.

[0060] In some embodiments, the rear side of the front bucket sidewall 22 and the front side of the rear bucket sidewall 14 are both provided with serrated structures 141. The serrated structures 141 can improve the stability of material gripping when the front bucket 20 and the rear bucket 10 are closed.

[0061] According to an embodiment of this utility model, in a second aspect, an engineering machinery is also provided, including a mechanical body; as provided in any embodiment of the first aspect, the bucket is fixed to the mechanical body by a bucket mounting plate 60. The engineering machinery may include earthmoving machinery, compaction machinery, skid steer loaders, etc. Since the engineering machinery includes the bucket described in the first aspect, it has the same beneficial effects as the bucket, which will not be elaborated further here.

[0062] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of the present invention.
