Description
Technical Field
The utility model belongs to bituminous paving maintenance of equipment field mainly relates to the hopper weighing device that can accurately weigh the road surface maintenance car of the raw and other materials of road surface maintenance.
Background
The maintenance of the asphalt pavement needs raw materials meeting the standard to ensure the construction quality of the pavement, so that the industrial production is the best choice. The road maintenance vehicle generally operates on site, and required raw materials are prepared on site. The pavement paving quality can be ensured only by accurately proportioning the reclaimed material and the new material. The feeding mechanism of the road maintenance vehicle does not have an accurate metering device, and the regenerant cannot be accurately added. The existing field metering mode generally adopts volume metering, and because the components of materials are different and the sizes of particles are different, the error of the volume metering is larger, so that the pavement paving effect is uneven, and the pavement paving quality is directly influenced. The weight metering mode is optimal, so that the accuracy of batching can be ensured, and the construction quality and the construction efficiency are improved.
Disclosure of Invention
The utility model aims at providing a hopper weighing device of road surface maintenance car, the device can guarantee the accuracy of measurement, improves the quality of road surface maintenance.
The utility model discloses a realize through following technical scheme, including hopper crane, hopper roll-over stand and hopper weighing device, the hopper passes through the hopper stores pylon and is connected characterized by with the couple on the hopper roll-over stand: weighing arms of symmetrically arranged hopper weighing devices are connected with an adapter plate on a hopper lifting frame through a rotating shaft, and weighing sensors are arranged at the front ends of the weighing arms; the weighing sensor is positioned below the supporting plates on the two sides of the hopper, and the weighing sensor is contacted with the supporting plates when the hopper falls down; the rear end of the weighing arm is connected with a cylinder rod of an oil cylinder through a connecting rod, and the other end of the oil cylinder is fixed on the hopper lifting frame through an oil cylinder seat; and a positioning block for adjusting the weighing arm to keep the horizontal position is arranged on the adapter plate.
The weighing sensor is connected with the control system.
The beneficial effects of the utility model are that, this weighing device sets up on the hopper crane of road surface maintenance car, and the arm of weighing uses the rotation axis to realize 90 degrees upsets through the hydro-cylinder is flexible as the center to realize weighing device's operating condition and transportation state. When the maintenance vehicle reaches the operation position and is in a working state, the cylinder rod of the oil cylinder is retracted, the front end of the weighing arm falls down, and the positioning block of the weighing arm is adjusted to enable the weighing arm to be placed in a horizontal position. The hopper falls down to press the supporting plates at the two sides of the hopper on the weighing sensor. At the moment, the hopper hanging frame is separated from the hook on the hopper overturning device, and the weighing accuracy is guaranteed. When the hopper is filled with materials, the control system measures the weight of a single time; after the materials are loaded for many times, the control system obtains the accumulated weight, and the accurate proportioning of the asphalt mixture is realized. After the use, the hopper is lifted to a specified height, the cylinder rod of the oil cylinder extends out, and the weighing arm is turned and erected, so that the transportation state is realized. The device can automatically complete the metering work, has the characteristics of continuous operation, accurate metering and high efficiency, and is suitable for the automatic weighing operation of a feeding mechanism and other feeding mechanisms of the pavement maintenance vehicle.
