Description

Technical Field

[0001] This invention relates to the field of engineering machinery, and more specifically to a loading device. Background Technology

[0002] Excavators and loaders are now widely used in various fields. However, due to the structural limitations of ordinary loading devices, such as fixed boom length and bucket direction, ordinary loading devices can hardly meet the requirements of flexible and variable loading and unloading height and flexible bucket working range in some special occasions such as forest farms, large warehouses and some narrow areas. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a loading device with a telescopic boom and a rotatable bucket, which has a larger working range than ordinary loaders. The loading device can meet the above requirements. By lifting the telescopic boom of this device, the bucket can overcome obstacles for loading and unloading operations. At the same time, the direction of the bucket can be controlled by controlling the different extension distances of the left and right telescopic booms. It has a high adaptability to working environments with many obstacles, such as forestry plants. In addition, through the reasonable design of the loading device, it has relatively good lifting translation and automatic leveling performance. The telescopic function of the left and right booms can adjust the unloading height, and the bucket's rotation can be controlled by the different extension lengths of the two booms, thereby increasing the loading and unloading range of the bucket.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a loading working device, comprising: a bucket, a left boom, a right boom, a front frame, and a steering structure. One end of the left boom and the right boom are respectively hinged to the left and right sides of the front frame, and the other end of the left boom and the right boom are connected to the bucket through the steering structure. The steering structure and the bucket are connected by a sliding pair. The left boom and the right boom have the same structure and have a telescopic function. By controlling the different lengths of the left boom and the right boom, the bucket can be rotated left and right.

[0005] Furthermore, the bucket is connected to the bucket steering structure via a sliding pair; the left boom ends a and b are hinged to the left steering structure, and end e is hinged to the front frame; the right boom ends c and d are hinged to the right steering structure, and end f is hinged to the front frame.

[0006] Furthermore, the left boom includes: a left bucket connecting rod, a left boom connecting rod, a left tipping cylinder, a first left boom, a second left boom, a left connecting rod, a left telescopic cylinder, and a left boom cylinder; the left bucket connecting rod is hinged to the left steering structure at hinge point a, and hinged to the left boom connecting rod at hinge point g; the g end of the left tipping cylinder is rotatably connected to the left bucket connecting rod, and the h end is rotatably connected to the left connecting rod; the left connecting rod is welded to the first left boom; the first left boom and the second left boom are connected by a sliding pair, and the power source for sliding is provided by the left telescopic cylinder; one end of the left telescopic cylinder is hinged to the first left boom, and the other end is hinged to the second left boom; the second left boom is rotatably connected to the front frame at end e; one end of the boom cylinder is rotatably connected to the front frame, and the other end is rotatably connected to the second left boom.

[0007] The right boom includes: a bucket right connecting rod, a boom right connecting rod, a right tipping cylinder, a first right boom, a second right boom, a right connecting rod, a right telescopic cylinder, and a right boom cylinder; the bucket right connecting rod is hinged at end c to the right steering structure and at end l to the boom right connecting rod; the right tipping cylinder is rotatably connected at end I to the bucket right connecting rod and at end m to the right connecting rod; the right connecting rod is welded to the first right boom, and the first and second right booms are connected by a sliding pair, with the power source provided by the extension and retraction motion of the right telescopic cylinder; one end of the right telescopic cylinder is hinged to the first right boom, and the other end is hinged to the second right boom; the second right boom is rotatably connected to the front frame at end f; one end of the right boom cylinder is rotatably connected to the front frame, and the other end is rotatably connected to the second right boom.

[0008] Furthermore, the left and right telescopic cylinders are single-controlled, while the left and right boom cylinders are dual-controlled, ensuring the stability of the loading device during lifting and lowering. The bucket can rotate left and right by controlling the lengths of the left and right booms and increasing the bucket's horizontal degree of freedom through the bucket steering structure.

[0009] Furthermore, when the length of the right boom is less than the length of the left boom, the bucket rotates in the direction of the right boom; when the length of the left boom is less than the length of the right boom, the bucket rotates in the direction of the left boom.

[0010] The beneficial effects of this invention are: the overall structure is novel and reasonable. It changes the limitation of the fixed length of the loading device of the traditional excavator loader by adopting a telescopic boom structure, which increases the lifting height and unloading height. At the same time, the telescopic boom structure is reasonably designed to achieve the effect of left and right rotation of the bucket, which expands the working range of the loading device. The loading device of this invention controls the direction of the bucket during operation by cleverly designing the telescopic distance between the left and right booms. It also has a variable unloading height, which improves the working flexibility of the loading device and expands its working range. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of the invention.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0019] like Figure 1As shown, a loading device includes: a bucket 1, a left boom 2, a right boom 4, a front frame 3, and a steering structure 5. The bucket 1 is connected to the bucket steering structure 5 via a sliding pair. The left boom 2a and b ends are hinged to the left steering structure 51, and the e end is hinged to the front frame 3. The right boom c and d ends are hinged to the right steering structure 52, and the f end is hinged to the front frame 3.

[0020] The loading device is equipped with a telescopic structure for the left boom 2 and the right boom 4, and the left telescopic cylinder 25 and the right telescopic cylinder 44 are individually controlled. By controlling the different lengths of the left boom 2 and the right boom 4, and by using a sliding pair connection between the bucket steering structure 5 and the bucket 1, the left and right rotation of the bucket can be achieved.

[0021] Specifically in this embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the left boom 2 in this embodiment includes a bucket left connecting rod 21, a boom left connecting rod 22, a left tipping cylinder 23, a first left boom 24, a second left boom 27, a left connecting rod 26, a left telescopic cylinder 25, and a left boom cylinder 28. Specifically, the left telescopic cylinder 25 is located below the first left boom 24. The left boom 2 is powered by the left telescopic cylinder 25, which allows the first left boom 24 to slide relative to the second left boom 27 along axis C, thereby changing the length of the left boom 2. Specifically, when the left boom cylinder 28 provides the power source, the left boom 2 relative to the front frame 3... At hinge point e, the boom cylinder 28 rotates around axis B, and the boom cylinder 28 rotates around axis A, thereby controlling the lifting and lowering of the left boom 2. Specifically, the left bucket cylinder 23 is above the first left boom 24 and the second left boom 27. The h end of the left bucket cylinder 23 is hinged to the left connecting rod 26, the left connecting rod 26 is fixedly connected to the first left boom 24, and the g end of the left bucket cylinder 23 is hinged to the left connecting rod 21 of the bucket. The left connecting rod 21 of the bucket is hinged to the left connecting rod 22 of the boom. The extension and retraction of the left bucket cylinder 23 cause the left steering structure 51 and the bucket 1 to rotate together around hinge point b.

[0022] Specifically in this embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the right boom 4 in this embodiment includes a bucket right connecting rod 41, a boom right connecting rod 42, a right tipping cylinder 43, a first right boom 45, a second right boom 47, a right connecting rod 46, a right telescopic cylinder 44, and a right boom cylinder 48.

[0023] Specifically, the right telescopic cylinder 44 is located below the first right arm 45 and the second right arm 47, which are connected by a sliding joint. By controlling the extension and retraction of the right telescopic cylinder 44, the first right arm 45 slides relative to the second right arm 47 along axis D. Both the left telescopic cylinder 25 and the right telescopic cylinder 44 are single-controlled. Specifically, the right arm cylinder 48 is connected below the second right arm 47 via a hinge. When the right arm cylinder 48 provides power to the right arm 4, the right arm 4 rotates around axis B at the hinge point f with the front frame 3. Specifically, the left arm... The boom cylinder 28 and the right boom cylinder 48 are dual-controlled to ensure that the left boom 2 and the right boom 4 are raised and lowered simultaneously. Specifically, the right bucket cylinder 43 is located above the first right boom 45 and the second right boom 47. The I end of the right bucket cylinder 43 is hinged to the right connecting rod 41 of the bucket and the right connecting rod 42 of the boom, and the m end is hinged to the right connecting rod 46. The other end of the right connecting rod 46 is fixed to the first right boom 45. Specifically, when the right bucket cylinder 43 performs extension and retraction movements, it drives the right connecting rod of the bucket to rotate around the axis E at the hinge point c, which in turn drives the first right boom 45 to rotate around the axis H at the hinge point d relative to the right steering structure 52.

[0024] Specifically, in the embodiment, the bucket 1 achieves unequal lengths of the left boom 2 and the right boom 4 by individually controlling the left telescopic cylinder 25 and the right telescopic cylinder 44; specifically, the left steering structure 51 can rotate left and right around axis F1, and the right steering structure 52 can rotate left and right around axis F2; ​​specifically, the bucket steering structure 5 and the bucket 1 are connected by a sliding pair; when the left boom 2 is longer than the right boom 4, the bucket steering structure 5 slides relative to the bucket 1, and the bucket 1 rotates towards the right boom 4; when the left boom 2 is shorter than the right boom 4, the bucket 1 rotates towards the left boom 2; specifically, when the extension and retraction distances of the left boom 2 and the right boom 4 are the same, the lifting height and unloading height can be increased or decreased, improving the adaptability of the loading device under different working conditions.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
