[0002] Transport vehicle, such as grain transport machine, fertilizer spreader, muck truck and agricultural trailer, belongs to the category of transport vehicle, and a covering device is needed to shield the top of the vehicle compartment in order to prevent the environmental protection demand of material splashing in the vehicle compartment and the protection demand of rainwater falling into the vehicle compartment during use. The industry usually adopts manual tarpaulin covering method to shield the top of the vehicle compartment. Workers are more dangerous to climb up and down the vehicle compartment, and the labor intensity is larger, and the work efficiency is low. Therefore, a kind of transport car tarpaulin hydraulic folding mechanism is provided. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model provides a kind of transport car tarpaulin hydraulic folding mechanism, which is driven to swing by hydraulic cylinder, to realize the purpose of quick folding and unfolding tarpaulin.

[0004] The technical scheme of the utility model is as follows: a kind of transport car tarpaulin hydraulic folding mechanism, including fixed frame, swing frame, drive frame, driven frame, oil cylinder, fixed seat, connecting rod one, connecting rod two, connecting rod three, connecting rod four, connecting rod five, tarpaulin, the bottom end of fixed frame, the bottom end of swing frame and the bottom end of oil cylinder are coaxially hinged on fixed seat, the bottom end of drive frame is hinged in the middle position of fixed frame, the upper end of oil cylinder is hinged at the drive hinge hole of drive frame, the bottom end of driven frame is hinged in the middle position of swing frame, a pair of fixed frame, swing frame, drive frame, driven frame, oil cylinder and fixed seat are arranged in front and back symmetry, the middle position of drive frame and driven frame is coaxially hinged at the shaft head of connecting rod five, the two ends of connecting rod one are fixed at the upper end of fixed frame, the two ends of connecting rod two are fixed at the upper end of driven frame, the two ends of connecting rod three are fixed at the upper end of drive frame, the two ends of connecting rod four are fixed at the upper end of swing frame, the hole one, hole two, hole three, hole four, hole five of tarpaulin are sequentially sleeved on connecting rod one, connecting rod two, connecting rod five, connecting rod three and connecting rod four.

[0005] The utility model has the advantages that the utility model is driven to swing by hydraulic cylinder, and the folding and unfolding of tarpaulin are realized, which is simple in structure and convenient to operate. BRIEF DESCRIPTION OF DRAWINGS
