Problems solved by technology
[0002] At present, as urban environmental protection requirements become more and more stringent, many urban dump trucks on the road must be covered with sealing devices to prevent secondary pollution. The opening and closing mechanism of the compartment top cover and the sealing cover device use two sets of oil cylinders for corresponding actions. It pulls the sprocket to rotate through the chain. When the sealing cover device is opened, one oil cylinder rotates the zipper chain, and the other oil cylinder serves as the delivery chain, and the sealing cover is closed. The functions of the two oil cylinders are opposite during the installation. The rotation of the sprocket drives the transmission shaft to rotate the crank of the sealing cover device to achieve the purpose of closing and opening the sealing cover. In addition, there is also an electric tarpaulin sealing cover device, and the service life of the tarpaulin is short. Disadvantages such as large size, easy chain breakage, complicated installation, high manufacturing cost, etc.

The invention relates to an opener for a hydraulic sealed cover of a dumper. The opener is characterized in that rack and gear kinematic pairs are driven by an oil cylinder to make rotational movement; through transmission shafts mounted in gears, four bar linkages swing; through track movement of the four bar linkages, top covers and side cover boards are driven to be totally opened or closed. The opener can cooperate with a pneumatic-hydraulic combination valve so as to form a hydraulic power unit, and the formed hydraulic power unit can simultaneously control the hoist, the descent and the interrupt of the dumper, and can totally close or open the sealed cover; an independent electric hydraulic power unit can also be adopted to cooperate with the opener. The opener has the advantages of simplified manufacturing technology, large rotating torque, reliable action, low manufacturing cost, good-looking appearance, simple operation and maintenance, and the like. The opener is suitable for dumpers which are used for transporting bulk materials and need covers; secondary pollution during transportation is avoided, so that the opener is particularly suitable for environmental sanitation departments to popularize and use.
