Automatically igniting and gas heating apparatus for paver ironing plate

The invention discloses a line type heater which comprises a gas inlet pipe and a line type heating pipe communicated with the gas inlet pipe. A plurality of fire spraying ports arranged along the length direction are arranged on the line type heating pipe. In at least one pair of adjacent fire spraying ports, the fire spraying port close to the gas inlet pipe is a near-end fire spraying port, and the fire spraying port away from the gas inlet pipe is a far-end fire spraying port, wherein the area of the near-end fire spraying port is smaller than that of the far-end fire spraying port. The invention further provides a paver using the line type heater to heat a screed plate. Due to the fact that in the line type heater, the area of the far-end fire spraying port away from the gas inlet is larger than that of the near-end fire spraying port close to the gas inlet pipe, the far-end fire spraying port away from the gas inlet pipe can contain more gas, and therefore burning stability of the fire spraying port away from the gas inlet can be improved.

A control method for a paver comprises: during the work process of a paver, as the included angle between a sensing arm (5) of a leveling instrument (4) of the paver and the vertical direction increases when a leveling oil cylinder (1) of the paver moves upward, performing computation according to a displacement difference between a current displacement of the leveling oil cylinder and the displacement where the leveling oil cylinder is most stable and an included angle difference between the included angle and a preset setting value of the included angle to obtain a compensational lifting pressure increment for a lifting oil cylinder (2); based on the compensational lifting pressure increment, increasing the compensational lifting pressure of the lifting oil cylinder to control the lifting oil cylinder of the paver to move upward. By means of the method, when aggregates (9) fail to support a screed (3) of the paver, the compactness and evenness of a formed road surface (7) are enhanced. Further disclosed are a paver, a control device for the paver, and a paver control system.
