Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and more specifically, to a tracked chassis hammer crusher. Background Technology

[0002] Cement concrete is a general term for engineering composite materials made by mixing cement, sand, stone, and other materials with water to form a whole. It has a wide range of applications, with road paving being one of the main uses of cement concrete. Currently, my country still has a significant number of concrete roads. As cement concrete roads age, their load-bearing capacity and strength weaken. Therefore, when cement concrete pavements reach the end of their service life and can no longer serve their function, they need to be treated to construct a new pavement structure. Currently, the commonly used process is crushing, which involves using a cement pavement crusher to break up the original pavement surface and using the resulting crushed stone as raw material for the new pavement, serving directly as the base or subbase. The crushing process eliminates the need to remove the damaged cement panels, saving on roadbed materials and transportation costs, achieving environmental protection and energy conservation goals, accelerating construction progress, and significantly reducing project costs.

[0003] Existing concrete pavement crushers typically only break concrete pavement into larger concrete blocks, which cannot be directly used as graded crushed stone. Instead, they require further crushing on-site using other crushing machinery to achieve the required graded crushed stone, or the concrete blocks must be transported to a specialized crushing site for further crushing before being laid back on the original roadbed. This increases the workload, reduces overall efficiency, and significantly increases manpower and material costs. For concrete pavements with high concrete grades and thick panels, existing crushers are incapable of handling the task. Effectively addressing these issues is a crucial direction for the development of concrete crushers. Utility Model Content

[0017] Convenient material conveying and distribution: the rear conveying auger and the distribution auger work together to transport and spread crushed materials onto the road surface, realizing one-stop construction of "crushing-conveying-paving" and improving efficiency.

[0018] The hydraulic drive mechanism controls the front clearing cylinder and the tensioning cylinder, enabling the clearing scraper to move back and forth and up and down. It can remove road debris and also adjust the track tension to prevent slippage and wear.

Detailed Implementation

[0027] 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.

[0028] Referring to the figure, this embodiment provides a tracked chassis hammer crusher, including a crusher main unit 1 and a power system installed on the crusher main unit 1. The power system includes an engine 2 and a transfer case 3 that is driven and connected to the output shaft of the engine. The output end of the transfer case is driven and connected to a multi-oil pump drive system 4. The multi-oil pump drive system 4 drives and connects a feeding crushing system, a tracked walking system, a material conveying and distributing system, and a obstacle clearing system.

[0029] Preferably, the feeding and crushing system 5 includes a feeding motor 51 driven by a multi-oil pump drive system. The feeding motor 51 is connected to a vibrator via a plate belt coupling. The feeder vibrator generates vibration, causing the material to move in the feeding trough 52, thereby realizing the feeding into the crushing box 53.

[0030] Preferably, the feeding and crushing system further includes a crushing box 53, a crushing main shaft 54 ​​is rotatably installed inside the crushing box 53, and a crushing hammer 55 that is linked to the crushing main shaft is provided inside the crushing box 54.

[0031] Preferably, the feeding and crushing system further includes a crushing transmission transition mechanism, which includes a drive pulley 56, a driven pulley 57 and a transmission belt. The drive pulley 57 is connected to the engine flywheel via a plate belt coupling, and the driven pulley 57 is fixedly connected to the crushing main shaft 58.

[0032] Preferably, the material conveying and distribution system 6 includes a rear conveying auger 61 and a distribution auger 62 driven by a multi-oil pump drive system;

[0033] The rear conveying auger 61 is located at the bottom discharge port of the crushing box 53 and is used to convey the crushed material to the rear of the crusher host.

[0034] The material distribution auger 62 is located at the rear of the crusher main unit and is used to spread the crushed material conveyed to the rear end onto the road surface.

[0035] Preferably, the obstacle clearing system 7 includes a hydraulic drive mechanism driven and controlled by a multi-oil pump drive system, the hydraulic drive mechanism controlling the front obstacle clearing cylinder 71 and the tensioning cylinder;

[0038] The working principle of the above embodiments is as follows:

[0039] The engine output shaft drives the transfer case via a belt coupling, and the transfer case synchronously distributes power to the multi-oil pump drive system. A flexible rubber plate cushions the engine starting shock, preventing belt slippage or breakage caused by a rigid coupling.

[0040] During the walking phase: The multi-pump drive system can drive the left and right walking wheels independently, and achieve steering, forward movement, and reverse movement by independently controlling the flow of the left and right oil pumps.

[0041] Feeding stage: The multi-oil pump drive system drives the feeding motor, which drives the vibrator to vibrate the feeding trough through the plate belt coupling, and transmits the stone material to the crushing box.

[0042] The crusher transmission transition mechanism works as follows: The drive pulley is connected to the engine flywheel via a belt coupling. When the engine is running, power is transmitted to the drive pulley, causing it to rotate. The drive pulley then drives the driven pulley to rotate via the transmission belt.

[0043] Crushing stage: The passive pulley is fixedly connected to the crushing main shaft extending into the crushing chamber, thereby driving the crushing main shaft to rotate. The breaker hammer rotates with the crushing main shaft, impacting and crushing the material.

[0044] Material distribution and conveying mechanism: The multi-oil pump drive system drives the rear conveying auger to transport the crushed material to the rear end of the crusher. At the same time, the distribution auger is controlled to rotate, spreading the material to the rear of the vehicle, and excess stone is distributed to both sides.

[0045] Compared with the prior art, the beneficial effects of this utility model in the above embodiments and working principles are as follows:

[0046] The engine, paired with a transfer case and a multi-oil pump drive system, precisely distributes power to the feeding and crushing, track walking, material conveying and distribution, and obstacle clearing systems. Each system operates independently, improving energy utilization and reducing energy consumption.

[0047] The feeding motor is connected to the vibrator via a plate belt coupling to achieve vibration feeding and avoid blockage; the crushing transmission transition mechanism adopts belt drive to buffer impact and reduce noise; the crushing main shaft is linked with the crushing hammer, which can effectively crush high-hardness materials with uniform particle size.

[0048] Convenient material conveying and distribution: the rear conveying auger and the distribution auger work together to transport and spread crushed materials onto the road surface, realizing one-stop construction of "crushing-conveying-paving" and improving efficiency.

[0049] The hydraulic drive mechanism controls the front clearing cylinder and the tensioning cylinder, enabling the clearing scraper to move back and forth and up and down. It can remove road debris and also adjust the track tension to prevent slippage and wear.

[0050] With multiple oil pumps driving the wheels, the tracked chassis can perform actions such as turning on the spot and climbing slopes, adapting to narrow construction areas, and the low ground pressure reduces secondary damage to the road surface.

[0051] Flexible belt coupling: The flexible rubber belt coupling is used to buffer the impact of engine starting and extend the service life of transmission components.
