Description

Technical Field

[0001] This utility model relates to the field of road construction machinery technology, and in particular to a paver hopper fixing structure. Background Technology

[0002] Pavers are key pieces of equipment in road construction, playing a central role in the paving of highways, airport runways, and other road surfaces. They can precisely and evenly lay various road construction materials, such as asphalt mixtures and cement-stabilized soil, on the road base. Through the coordinated operation of the auger spreader and screed, the pavement can be ensured to meet the specified requirements for smoothness, thickness, and compaction, greatly improving the quality and efficiency of road construction.

[0003] The hopper, a crucial component of the paver, is located at the front of the equipment. Its primary function is to store and supply material to the conveying system. Typically constructed of high-strength steel, it boasts a large capacity, reducing the frequency of material feeding and ensuring continuous construction. A scraper conveyor at the bottom of the hopper uniformly transports material backward to the auger spreader, achieving stable material delivery. Furthermore, some advanced pavers are equipped with automatic material receiving devices in their hoppers, which can flexibly adjust their position to efficiently receive material as transport vehicles unload, further enhancing the smoothness of construction.

[0004] In the existing technology, for safety reasons, the hopper of the paver needs to be closed and fixed when it is moved to another site. The traditional method is to set a pin on the hopper. When it is necessary to fix the hopper, the operator first closes the hopper on the control panel, and then gets off the machine to insert the pin of the hopper into the hole in the machine body to fix it. When unfixing, the operator needs to get off the machine again to pull out the pin. The process is cumbersome and reduces the operator's work efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the problems in the background technology and provide a hopper fixing structure for a paver. By setting this fixing structure, the operator can easily perform the work of fixing and releasing the hopper without getting off the machine by operating the throttle control handle, which effectively improves the operator's work efficiency and has good promotional value.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a paver hopper fixing structure, including a hook rotatably mounted on the side wall of the front plate of the machine body, a connecting rod integrally provided on the side of the hook away from the hopper, the end of the connecting rod away from the hook being connected to the flexible shaft of the operating flexible shaft, and the handle of the operating flexible shaft being installed next to the driver's seat;

[0007] An elongated hole (11) for the hook (4) to extend is provided on the front panel of the machine body located between the hopper and the hook;

[0008] A fixing plate is welded to the side wall of the front panel of the machine body located below the connecting rod. A spring is installed between the fixing plate and the connecting rod. The function of the spring is to provide auxiliary force for turning the handle and to provide a holding force for the hook body in its current state.

[0009] Furthermore, the hook is mounted on a pin on the side wall of the front panel of the machine body via a cotter pin and a retaining ring, and the hook can rotate around the pin welded to the machine body.

[0010] Furthermore, the hook is provided with a first slot, and the hopper is provided with a second slot that engages with the first slot. The engagement of the first slot and the second slot fixes the hook and the hopper together and prevents the hook from detaching.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets a rotatable hook at the front plate of the paver body. The operator controls the hook to extend or retract at the front plate of the machine body by operating the handle of the flexible shaft, so as to fix or release the hook from the hopper. In both processes, the operator does not need to get off the machine to fix or release the hopper. The operation is simple, reduces the operator's labor intensity, and improves work efficiency. It solves the technical problem in the prior art that the operator must get off the machine to insert or pull the pin of the hopper into or out of the machine body hole in order to fix or release the hopper, which leads to a cumbersome process.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Of course, the specific embodiments described herein are only for explaining this utility model and are not intended to limit it.

[0017] Example

[0018] like Figures 1-3As shown, this embodiment provides a paver hopper fixing structure, including a hook 4 rotatably mounted on the side wall of the front plate 2 of the machine body. The hook 4 is mounted on a pin on the side wall of the front plate 2 of the machine body via a cotter pin 3 and a retaining ring 5. The hook 4 can rotate around the pin welded to the machine body. A connecting rod 13 is integrally provided on the side of the hook 4 away from the hopper 1. The end of the connecting rod 13 away from the hook 4 is connected to the flexible shaft 7 of the operating flexible shaft 9. The handle 8 of the operating flexible shaft 9 is installed next to the seat in the cab. A spacer is provided on the front plate 2 of the machine body between the hopper 1 and the hook 4 for... The hook 4 extends through an elongated hole 11; a fixing plate 10 is welded to the side wall of the front panel 2 of the machine body below the connecting rod 13. A spring 6 is installed between the fixing plate 10 and the connecting rod 13. The function of the spring 6 is to provide auxiliary force for rotating the handle 8 and to provide a holding force for the hook 4 in its current state. The hook 4 is provided with a first slot 12, and the hopper 1 is provided with a second slot that engages with the first slot 12. The hook 4 is fixed to the hopper 1 by engaging the first slot 12 with the second slot. The two slots prevent the hook 4 from coming off.

[0019] The flexible shaft is equipped with a ratchet structure. When turning the handle 8, it is necessary to lift it up slightly first. Only after lifting the handle 8 and releasing the positioning can the handle 8 be turned. After the rotation is completed, the handle 8 will be automatically fixed by the ratchet structure.

[0020] When in use, when it is necessary to move the hopper 1, the operator first holds the handle 8 and lifts it upward and rotates it. The handle 8 drives one end of the connecting rod 13 downward through the flexible shaft 7. The other end of the connecting rod 13 pushes the hook 4 to rotate forward around the pin shaft. The lower end of the hook 4 passes through the elongated hole 11 and extends out of the front plate 2 of the machine body. The operator manipulates the hopper 1 to fall back, and the second slot on the hopper 1 engages with the first slot 12 on the hook 4, thus fixing the hopper 1. When it is necessary to release the hopper 1, first manipulate the hopper 1 to lift it up, and the first slot 12 separates from the second slot. Then, hold the handle 8 and lift it upward and rotate it back. Similarly, the handle 8 will drive the hook 4 to retract into the front plate 2 of the machine body through the flexible shaft 7 and the connecting rod 13. The flexible shaft 7 is automatically fixed by manipulating the ratchet inside the flexible shaft. The hopper 1 can be extended and put into working state. At this time, the hopper 1 is released from the fixation. Throughout the process, the spring 6 is used to provide auxiliary force for rotating the handle 8 and to provide holding force for the hook 4 in its current state.

[0021] In summary, the operator can easily fix and release the hopper 1 by manipulating the handle 8 of the flexible shaft 9. The entire operation does not require the operator to get off the machine, making it simple to operate, which helps reduce the operator's workload and improve work efficiency.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
