Further, as a self-propelled mortar, a vehicle-mounted mortar in which a shock absorber is mounted in a room of a large vehicle and a mortar is mounted thereon is used.

In the case of a mortar equipped with wheels, it was necessary to separate the mortar from the towing vehicle, then stably install the mortar on the ground and manually adjust the shooting direction to shoot. In the case of a mortar mounted on a tow trailer, the support legs provided on the tow trailer are expanded and extended to raise the tow trailer base to the extent that the tow trailer tires move away from the ground, and then the tow trailer tire It was necessary to bounce it up to disconnect it from the ground and then contract the support legs to ensure stable support against impact during shooting. After that, it was necessary to manually adjust the shooting angle direction and also to manually correct the shooting angle by the gun crawling into the ground after the launch.

In a vehicle-mounted mortar, it was necessary to mount a shock absorber in the vehicle compartment and to mount the mortar on the shock absorber in order to absorb the reaction force from the shooting, so that the mortar can be mounted. Vehicles were limited to large vehicles.

A pair of left and right lifting cylinders 14, a shooting angle cylinder 15, and an azimuth angle cylinder 19 as a drive unit in the azimuth angle adjusting mechanism 35 are provided with stroke sensors 20 for detecting respective cylinder stroke amounts.

In FIG. 8, an example in which the azimuth cylinder 19 is used as a drive unit for driving the barrel 12 of the mortar in the azimuth adjusting mechanism 35 in the azimuth direction will be described. However, as described in FIG. 6, the azimuth adjustment mechanism 35
When the azimuth angle motor 16 is used as the drive unit in FIG. 1, the same operation as that of the azimuth angle cylinder 19 will be described. That is, the azimuth motor 16 is used as a drive unit in the azimuth adjusting mechanism 35 instead of the azimuth cylinder 19, and the movement amount of the moving member 37 is detected by a detection signal from a sensor that detects the rotation amount and the rotation direction of the motor. Then, by using the same movement amount instead of the detection signal from the stroke sensor of the azimuth angle cylinder 19, the control described below can be performed.

Based on the control signal from the shooting control device 3, the pump drive motor is started to supply the pressure oil from the hydraulic pump 24. Further, based on a control signal from the shooting control device 3, the switching of the solenoid valves 22-1 to 22-4 for driving a desired cylinder is controlled. Hydraulic pump 2
When pressure oil is supplied from 4 to the pair of lifting cylinders 14, the outrigger frame is moved up and down, and the storage position of the mortar in the vehicle and the ground installation position can be switched. Also, the shooting angle cylinder 15 and the azimuth angle cylinder 19
When the pressure oil is supplied to the mortar, the mortar can be set in a desired shooting direction according to the supply amount of the pressure oil.

By feeding back the detection value from the inclination angle sensor 21 and the cylinder stroke amount from each stroke sensor to the shooting control device 3, the mortar can be automatically set in a desired shooting direction. After the mortar is set in the desired angle of incidence, the mortar fires a projectile. When the flying object has not landed at the target point, a correction signal is sent from the firing control device 3 to the solenoid valve 22 of the corresponding cylinder so that the landing position of the flying object becomes the target position.

Further, when the outrigger frame digs into the ground when the mortar is fired, the detection signal from the stroke sensor 20 provided in each cylinder and the inclination angle sensor 21.
A signal for modifying the firing angle direction of the mortar based on the tilt angle from is sent to the solenoid valve 22 of the corresponding cylinder. As a result, as shown in FIG. 12, the projectile fired from the mortar can land on the target point.

The tilt angle sensor 21 may be arranged so as to detect tilt angles in two orthogonal directions. Also,
The tilt angle sensor 21 may detect a tilt angle in one of two orthogonal directions, and the tilt angle in the other direction may be detected using the respective detection values from the stroke sensors of the pair of lifting cylinders 14. By the way, when the azimuth angle motor 16 is used in the azimuth angle adjusting mechanism 35, the shooting controller 3 controls the drive current supplied to the azimuth angle motor to control the position of the barrel 12 in the azimuth direction. be able to.

As a method of displaying the vehicle stop direction by the shooting control device 3, a method of simultaneously displaying the vehicle direction and the target stop direction on the display, a voice instruction, or an indication of the direction of the target stop direction by voice, characters, or the like is appropriately used. The display method of can be used. (3) The vehicle is stopped in a predetermined direction based on the display. After that, the shooting control device 3 outputs a deployment instruction signal for the outrigger frame 10. (4) In response to the expansion instruction signal, the lifting cylinder 14 expands and expands from the state of FIG. 9A to the state of FIG. 9B. When the shooting control device 3 detects that the extension of the elevating cylinder 14 is stopped by the detection value from the stroke sensor 20 provided in the elevating cylinder 14, it issues a command to stop the extension operation of the elevating cylinder 14.

(5) Based on the position data from the GPS device 2, the position data of the target point, the launch position data, and the detected value from the inclination angle sensor 21, the altitude difference between the point where the vehicle stops and the target point, the straight line The shooting control device 3 calculates based on the meteorological data such as the distance, the inclination angle of the ground, and the wind speed that is separately detected. Based on the calculation result, the azimuth angle motor 16 or the azimuth angle cylinder 19 and the shooting angle cylinder 15 as the driving unit of the azimuth angle adjusting mechanism 35 are controlled to set the mortar to face the shooting direction. At this time, the detection value by the stroke sensor or the like in the azimuth motor 16 or the azimuth cylinder 19 and the shooting cylinder 15 is fed back to the shooting control device 3 by feedback, so that the shooting direction and the azimuth direction are automatically detected. Control can be performed. (6) After completing the setting of the mortar in the shooting angle direction, shoot the projectile from the mortar. At this time, in order to mitigate the transmission of the shooting reaction force generated when the projectile is launched to the vehicle body, the solenoid valves 22-1 and 22-2 are switched to each cylinder chamber in each lifting cylinder 14. The cylinders 14 for raising and lowering can be left free by making them communicate with each other. (7) Detection value of the stroke sensor 20 of each cylinder after launching the projectile, and when the azimuth motor 16 is used, the azimuth motor 16 rotated by the impact of launching the projectile
