Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a new type of telescopic baffle structure for a spiral material distributor and its paver. Background Technology

[0002] With the development and evolution of pavers, their various functions have gradually matured and stabilized. As a result, while ensuring the stability of these functions, the ease of use of the equipment has become a key concern.

[0003] The baffle structure of the auger on existing pavers is generally detachable. Different width baffles are assembled to match the width of the auger, depending on the width of the auger. Due to varying road widths and different working conditions, workers or operators need to frequently disassemble and assemble the baffles. This high-intensity physical labor consumes a significant amount of time and severely impacts work efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel telescopic baffle structure for a spiral material distributor and its associated paver. This device can effectively solve the problem of frequent disassembly and assembly of the baffle under different working conditions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a novel telescopic baffle structure for a spiral feeder, including a liftable main spiral feeder, a left telescopic baffle, and a right telescopic baffle. The liftable main spiral material distributor is connected to the rear plate of the vehicle frame via a spiral lifting cylinder. The left telescopic baffle and the right telescopic baffle are respectively hinged to the liftable main spiral material distributor via folding and rotating hinge shafts. A first support rod bracket and a second support rod bracket are fixedly installed on the rear plate of the frame. The first support rod bracket is hinged to one end of the left support rod via a first hinge pin. The second support rod bracket is hinged to one end of the right support rod via a second hinge pin. The other end of the left support rod is hinged to the left telescopic baffle via a support rod and baffle connecting hinge pin device. The other end of the right support rod is hinged to the right telescopic baffle via a support rod and baffle connecting hinge pin device.

[0006] The left telescopic baffle, the right telescopic baffle, and the liftable main spiral feeder switch between folded, non-telescopic, and telescopic working states through the cooperation between the folding fixing pin and the telescopic plate fixing pin.

[0007] Preferably, the first hinge shaft is provided with multiple mounting holes, and different mounting holes are selected to connect with the left support rod and the right support rod to adapt to different working heights of the liftable main spiral feeder.

[0008] Preferably, both the first support rod bracket and the second support rod bracket are fixedly connected to the track steel structure of the paver.

[0009] Preferably, the left telescopic baffle and the right telescopic baffle can extend and retract along the length of the liftable main auger spreader to adapt to different paving width requirements.

[0010] Preferably, in the folded state, the left telescopic baffle and the right telescopic baffle rotate around the folding hinge axis until they are parallel to the frame. The left telescopic baffle and the right telescopic baffle are locked by the folding fixing pin, and the first hinge axis and the second hinge axis are fixed to complete the folding fixation.

[0011] Preferably, in the non-extended working state, the left and right telescopic baffles rotate backward around the folding hinge axis, and the support rod and the baffle connecting hinge device rotate synchronously, and are fixed to the second support rod bracket through the second hinge.

[0012] Preferably, in the telescopic working state, after loosening the telescopic plate fixing pin, pulling the left telescopic baffle and the right telescopic baffle to the preset width, the telescopic plate fixing pin is locked again to complete the width fixing.

[0013] Preferably, both the left and right support rods are rigid rods, which are hinged to the corresponding brackets through the first hinge shaft and the second hinge shaft. The left and right telescopic baffles adjust their heights according to the lifting and lowering action of the liftable main spiral feeder to maintain the baffle adaptation posture.

[0014] Preferably, a paver is equipped with the telescopic baffle structure of the novel spiral distributor described above.

[0015] The present invention proposes a novel telescopic baffle structure for a spiral distributor and a paver thereof. The advantages of this invention are as follows: the telescopic baffle does not need to be disassembled; it only requires adjustment of different telescopic lengths and the use of locking pins to fix the required width. This is convenient, quick, and easy to use. Moreover, this baffle can rise and fall with the spiral distributor to meet the needs of various paving thickness conditions. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A novel telescopic baffle structure for a spiral material distributor and its paver are disclosed. The rear plate 10 of the frame is located at the rear of the device and serves as a fixed reference. The first support rod bracket 6 and the second support rod bracket 7 are directly fixed to the track steel structure and serve as the support base points for the right support rod 4 and the left support rod 5, respectively, and are distributed on both sides of the frame.

[0022] The liftable main spiral feeder 1 is located in the middle of the device, with the left telescopic baffle 2 and the right telescopic baffle 3 symmetrically arranged on the left and right sides, forming a "main in the middle and auxiliary on the left and right" layout.

[0023] The spiral lifting cylinder 12 is connected between the liftable main spiral material distributor 1 and the rear plate 10 of the frame, and is used to drive its lifting; the left support rod 5 and the right support rod 4 are respectively connected to the left telescopic baffle plate 2 and the right telescopic baffle plate 3.

[0024] The support rod and baffle connecting hinge device 15 is a connecting node component, and the folding fixing locking pin 8 and the telescopic plate fixing locking pin 9 are locking components, which are installed on the telescopic end of the hinge node and the baffle plate respectively.

[0025] The components are connected by a combination of hinges and fixings to ensure flexibility of movement and stability of operation. The specific connection relationships are as follows: The liftable main spiral feeder 1 and the baffle plate are hinged together by a folding fixing pin 8 and a folding rotating hinge shaft 11. The baffle plate can rotate relative to each other around the shaft to switch between folding and unfolding. The folding fixing pin 8 is inserted and locked after the baffle plate is rotated into place to prevent accidental shaking.

[0026] The extension and retraction of the spiral lifting cylinder 12 directly pulls the entire liftable main spiral feeder 1 to rise and fall. Due to the hinge connection, it also drives the left telescopic baffle 2 and the right telescopic baffle 3 to rise and fall synchronously.

[0027] One end of the left support rod 5 is hinged to the left telescopic baffle plate 2 via the support rod and baffle connecting hinge device 15. The other end of the left support rod 5 is hinged to the first bracket 6 via the second hinge 14. The right support rod 4 is symmetrically arranged on both sides of the liftable main spiral feeder 1 with the left support rod 5. The connection method of the right support rod 4 is the same as that of the left support rod 5.

[0028] The first hinge shaft 13, through its engagement with adjustment holes at different heights on the hinge shaft device 15 connecting the support rod and the baffle, enables adjustment of different working heights.

[0029] The first hinge 13 is connected to the support rod and the baffle through the adjustment holes at different heights on the hinge device 15.

[0030] Both the first support rod bracket 6 and the second support rod bracket 7 are rigidly fixed to the track steel structure of the paver, providing a stable support benchmark for the support rod and ensuring the stability of the baffle plate in the folded or working state. The first support rod bracket 6 is the support rod bracket in the folded state, and the second support rod bracket 7 is the support rod bracket in the working state.

[0031] One end of the left telescopic baffle 2 and the right telescopic baffle 3 can be extended laterally. Both the left telescopic baffle 2 and the right telescopic baffle 3 are double-layered plates. The relative position of the double-layered plates is achieved through sliding slots. By dragging the movable end of the baffle, the horizontal extension and retraction can be achieved. After extension and retraction, the locking pin 9 of the telescopic plate is used to lock the plate and fix the width after adjustment.

[0032] This device adapts to different paving conditions through its triple functions of "retractable, foldable, and height-adjustable baffles." It is categorized by "working status," allowing for quick switching between statuses without disassembling the baffles, as follows: First state: Folded state, suitable for relocation or non-working conditions, such as paver relocation and transportation, or when only the liftable auger spreader 1 is needed without unfolding the left telescopic baffle 2 and right telescopic baffle 3, and only the inherent width is used for operation.

[0033] Rotate the left telescopic baffle 2 and the right telescopic baffle 3 toward the frame around the folding hinge axis 11 until the baffles are parallel to the rear plate 10 of the frame. Insert the folding locking pin 8 to fix the first hinge pin 13 and the second hinge pin 14, and the folding state can be achieved.

[0034] The core advantage is that there is no need to remove the baffle, which greatly reduces the space occupied during transportation and reduces the preparation time for relocation.

[0035] The second state: non-extension working state, which is suitable for conventional width paving conditions, that is, when the width of the paved road surface matches the inherent width of the liftable main auger spreader 1, and there is no need to expand the width of the baffle plate.

[0036] First, pull out the folding fixing pin 8, rotate the baffle plate backward away from the frame direction around the folding rotation hinge shaft 11, and simultaneously drive the support rod and the baffle plate connecting hinge shaft device 15 to rotate. The pin hole of the second hinge shaft 14 is aligned with the pin hole on the second support rod bracket 7 and fixed by the pin shaft, so that the unextended baffle plate remains in the extended state.

[0037] Check that the telescopic plate fixing pin 9 is in the locked state to prevent the baffle plate from extending or retracting unexpectedly.

[0038] Its core advantage is that it can quickly switch from folded to working mode. The operation steps are simple, no width adjustment is required, and it is suitable for conventional paving needs.

[0039] The third state: telescopic working state, suitable for wide paving conditions; that is, when the width of the paved road surface is greater than the inherent width of the main auger distributor, and the coverage of the baffle plate needs to be expanded.

[0040] First: Follow the procedure of "unextended working state" to complete the deployment and support fixation of the baffle plate; Next, pull out the telescopic plate fixing pin 9, and drag or pull out the left telescopic baffle plate 2 and the right telescopic baffle plate 3 outward according to the target paving width until the total width of the baffle plates matches the road width.

[0041] Finally, after the telescopic plate is fully extended, insert the telescopic plate fixing pin 9 into the corresponding hole of the telescopic section to lock the width of the baffle plate and prevent it from shifting during operation.

[0042] Its core advantage is that it replaces the traditional "removable and detachable baffle" by telescopic adjustment, adapting to different road widths and reducing labor time and intensity.

[0043] The device also features height adjustment to accommodate different paving thicknesses. When the paving thickness changes, the working height of the baffle plate must be adjusted synchronously to ensure that the baffle effect matches the paving thickness. At this time, the auger lifting cylinder 12 is activated, and the extension and retraction of the cylinder drives the main auger distributor 1 to rise and fall as a whole. The left telescopic baffle plate 2 and the right telescopic baffle plate 3, being hinged to the main distributor, rise and fall synchronously.

[0044] Based on the working height after lifting, adjust the connection holes of the first hinge shaft 13 with the support rod and the baffle connecting hinge shaft device 15 at different heights to adapt and adjust the height.

[0045] Ensure that the first hinge shaft 13, the second hinge shaft 14, the support rod and the baffle connecting hinge shaft device 15 are all locked in place to prevent the baffle plate from shaking due to vibration during operation.

[0046] This device integrates the functions of "telescopic, folding, and height adjustment" through a purely mechanical structure design. With the liftable main spiral material distributor 1 as the core connecting point, the device achieves the folding / unfolding of the baffle plate through hinges, the width adjustment through the telescopic extension of the baffle plate, and the height adaptation through a hydraulic cylinder and adjustable hinge shaft. Ultimately, it solves the pain points of traditional disassembly baffle plates, such as "frequent disassembly and assembly, high labor intensity, and high time consumption", thereby improving construction preparation efficiency and reducing costs.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
