Description

Technical Field

[0001] This utility model relates to the technical field of push rake equipment, and in particular to a push rake with an adjustable push rake shovel assembly. Background Technology

[0002] Push rakes are commonly used material handling and sorting equipment in engineering construction, agricultural production, and warehousing and logistics. Their core working component is the front-end push rake.

[0003] The existing pusher shovels of pusher machines are mostly fixed structures, which have the following shortcomings: the working area of ​​the pusher shovel is fixed. When it is necessary to handle large areas of loose material or materials in narrow spaces, the coverage range of the shovel cannot be flexibly adjusted, requiring multiple back-and-forth operations, which increases the working time and energy consumption; some expandable pusher shovels adopt a single expansion structure, which has a limited expansion range, and it is difficult to achieve synchronous control of each expansion component during the expansion process, which can easily lead to component jamming or inconsistent expansion, affecting the stability of operation.

[0004] To address the aforementioned issues, this invention proposes a rake pusher equipped with an adjustable rake shovel assembly. Through the coordinated operation of multiple components, the working area is expanded in stages, and the expansion components are controlled synchronously, thereby improving the adaptability and operational efficiency of the rake pusher.

[0005] Therefore, the existing technology of pusher equipment needs further improvement. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a rake pusher with an adjustable rake shovel assembly.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A rake pusher with an adjustable rake shovel assembly includes a rake pusher body and a rake shovel body. A control component is provided between the rake pusher body and the rake shovel body. A first extension shovel assembly is provided on the rake shovel body, and a second extension shovel assembly is provided on the first extension shovel assembly. An opening and closing control component is provided on the rake shovel body for synchronously controlling the closing or opening of the first extension shovel assembly and the second extension shovel assembly.

[0009] As described above, a rake pusher with an adjustable rake shovel assembly includes an angle control arm disposed on the rake pusher body for controlling the front and rear tilt angle of the rake shovel body, and a rotation control arm disposed on the rake pusher body for controlling the up and down tilt angle of the rake shovel body.

[0021] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1 to 3 As shown in the figure, this application embodiment provides a rake machine with an adjustable rake shovel assembly, including a rake machine body 1 and a rake shovel body 2. A control component 3 is provided between the rake machine body 1 and the rake shovel body 2. A first extension shovel assembly 4 is provided on the rake shovel body 2, and a second extension shovel assembly 5 is provided on the first extension shovel assembly 4. An opening and closing control component 6 is provided on the rake shovel body 2 for synchronously controlling the closing or opening of the first extension shovel assembly 4 and the second extension shovel assembly 5. The control component 3 controls the front and rear tilt angle of the rake shovel body 2 through an angle control arm 301, and controls its up and down flipping angle by rotating the control arm 302, thereby realizing the adjustment of the working angle.

[0023] When the vertical hydraulic push rod 601 of the tension control component 6 extends or retracts, it drives the swing connecting rod 6022 of the two side connecting rod assemblies 602 to swing around the second hinge axis 6023:

[0024] The middle part of the swing link 6022 pushes the first slider 402 to slide along the first transverse guide rail 401 through the second hinge shaft 6023, so that the first expansion shovel 403 can be opened or closed.

[0025] At the same time, the tail of the swing link 6022 cooperates with the drive shaft 6026 through the straight slot 6025, driving the second transverse slider 502 to slide along the second transverse guide shaft 501, so that the second expansion shovel 503 moves synchronously, and the moving speed of the second expansion shovel 503 is greater than that of the first expansion shovel 403.

[0026] In the initial state, the first extending shovel 403 and the second extending shovel assembly 5 are joined and overlapped inside the pusher shovel body 2, reducing the length to increase the thrust; when unfolded, the two open to the sides at a differential speed, expanding the area for pushing and raking soil.

[0027] The control component 3 of this utility model includes an angle control arm 301 disposed on the body 1 of the rake pusher and used to control the front and rear tilt angle of the rake pusher body 2, and a rotation control arm 302 disposed on the body 1 of the rake pusher for controlling the up and down tilt angle of the rake pusher body 2.

[0028] The first expansion shovel assembly 4 of this utility model includes two first transverse guide rails 401 symmetrically arranged on the push rake shovel body 2, a first slider 402 movably arranged in the first transverse guide rail 401, and a first expansion shovel 403 arranged on the first slider 402.

[0029] The second expansion shovel assembly 5 of this utility model includes a second transverse guide shaft 501 symmetrically disposed on the first expansion shovel 403 on the corresponding side, a second transverse slider 502 movably disposed within the second transverse guide shaft 501, and a second expansion shovel 503 disposed on the second transverse slider 502.

[0030] The opening and closing control component 6 of this utility model includes a vertical hydraulic push rod 601 disposed in the middle of the first transverse guide rails 401 on both sides, and a connecting rod assembly 602 disposed on each side of the push rake shovel body 2. The two connecting rod assemblies 602 are respectively connected to the connecting rod assembly 602 and the second extension shovel assembly 5 on the corresponding side. The connecting rod assembly 602 is connected to the output end of the vertical hydraulic push rod 601.

[0031] The linkage assembly 602 of this utility model includes a first hinge shaft 6021 disposed on both sides of the output end of the vertical hydraulic push rod 601. A swing link 6022 is hinged on the first hinge shaft 6021. A second hinge shaft 6023 is disposed on the first slider 402. A hinge shaft hole 6024 is disposed in the middle of the swing link 6022 and a straight groove 6025 is disposed at the tail. A drive shaft 6026 is disposed on the second transverse slider 502. The hinge shaft hole 6024 is hinged to the second hinge shaft 6023 on the corresponding side. The drive shaft 6026 is movably inserted into the straight groove 6025 on the corresponding side.

[0032] In the initial state, the first extending shovel 403 and the second extending shovel assembly 5 are joined together inside the pusher shovel body 2 to overlap, thereby increasing the thrust by reducing the length of the shovel body;

[0033] Under the control of the linkage assembly 602, the first expanding shovel 403 and the second expanding shovel assembly 5 can open at different speeds on both sides. The overlapping first expanding shovel 403 and the second expanding shovel assembly 5 will unfold to both sides. The moving speed of the second expanding shovel assembly 5 is greater than that of the first expanding shovel 403. The linkage assembly 602 completes the larger bulldozing and raking area of ​​the second expanding shovel assembly 5.

[0034] In summary, the embodiments of this application employ a two-stage expansion structure consisting of a first expansion shovel assembly and a second expansion shovel assembly. This allows for flexible adjustment of the shovel's coverage area according to the operational scenario, meeting the needs of large-area material handling while also adapting to operations in confined spaces, increasing thrust, reducing the number of reciprocating operations, and improving efficiency. The opening and closing control assembly, through the cooperation of a vertical hydraulic push rod and a connecting rod assembly, achieves synchronous differential expansion and closing of the first and second expansion shovel assemblies, avoiding issues such as component jamming or inconsistent movements, and ensuring a stable and reliable operation process.
