  A compression space 28 is provided between the rear end of the rotary shaft 22 and the outlet 6B of the compression conveyance chamber 6, and the outlet 6B can be closed by the reaction force plate 32 of the reaction force tray device 31. It has become. The reaction force tray device 31 is configured to serve as both a part of the compression means 5 and the discharge means 5. The reaction force tray device 31 includes a moving tray 33 having substantially the same width as the bottom surface 6 </ b> C of the compression transfer chamber 6, and the reaction force plate 32 is erected at the rear part of the moving tray 33.

Further, the position of the reaction force plate 32 can be fixed by using the brake of the drive motor 36 so that the reaction force plate 32 does not move even when it receives snow pressure. The screw conveyors 21L, 21R, 21L, and 21R apply a compressive force that compresses the snow in the compression space 28 toward the rear, which is one side direction. A reaction force in the direction opposite to the compression force is applied to the snow in the compression space 28.

First, the moving tray 33 is at a position where the reaction force plate 32 closes the carry-out port 6 </ b> B, and is fixed in position by the braking force of the tray drive motor 36. Snow is sent to the compression space 28 of the compression conveyance chamber 6 by the screw conveyors 21L, 21R, 21L, 21R and compressed. Since the reaction force plate 32 is fixed and the resistance of the screw drive motor 27 increases as the compression of the snow proceeds, in the motor 27, for example, if the current corresponding to the rated torque is exceeded as a threshold, It is determined that the compression state (compression density) has been reached, and the moving tray 33 is driven so that the reaction force plate 32 moves backward. In this case, the moving tray 33 is moved backward while applying a predetermined reaction force to the snow in the compression space 28. As a control method, analog control such as PID control or state feedback control may be used in addition to threshold control.

Further, guide members 65 are disposed in front of and behind the fluid pressure cylinder 64. The guide member 65 fixes the slide shaft 65A to the holding arm 62 and guides the slide shaft 65A. Have The slide shaft 65A has its axial direction aligned with the width direction of the machine body 2.

  Therefore, when the fluid pressure cylinder 64 expands and contracts, the holding arm 63 can be stably moved by the guide members 65 on both sides.

  Further, as shown in the schematic diagram of FIG. 8, the bottom surface 33A of the moving tray 33 is disposed at a slightly lower position than the bottom surface 6C of the compression transfer chamber 6.

In this case, as shown in FIG. 8, the snow block 101 is bent so that the upper surface side becomes a tensile region due to the height difference H between the bottom surface 6C of the compression transfer chamber 6 and the bottom surface 33A of the moving tray 33. The hardened snow block 101 can be cut and separated smoothly. When the blade 56A is lowered to the bottom surface 33A, the lifting drive motor 59 is stopped, the lifting body 55 is stopped, and the lowering is restricted by a stopper (not shown). At this position, the sandwiching arms 63 and 63 are in a position to sandwich the block unit 102 from the side, and the fluid pressure cylinder 64 is extended so that the sandwiching arms 63 and 63 sandwich the block unit 102. After this clamping, the elevating drive motor 59 is driven, the elevating body 55 is raised, and the block unit 102 is lifted to a position where the moving tray 33 can move forward as shown in FIG. The elevator 55 stops. When the elevating body 55 stops, as shown in FIG. 9B, the moving tray 33 moves forward, and the moving tray 33 stops at the position where the reaction force plate 32 closes the carry-out port 6B. When the moving tray 33 moves backward while applying a reaction force to the snow in the compression space 28 by the force plate 32 and moves back to a predetermined position, as shown in FIG. When the block unit 102 sandwiched by 63 rides on the snow block 101 on the moving tray 33, or as shown in FIG.

Furthermore, after the lifting body 55 is lowered, the snow block 101 is cut, and the clamped arms 63, 63 are clamped on the cut block unit 102, the lifting unit 55 is lifted, and the two stacked block units 102, 102 is lifted to a position where the moving tray 33 can move backward, and the lifting body 55 stops at this position. Thereafter, similarly, the next block unit 102 is cut and formed, and the three stacked block units 102, 102, 102 are lifted up to a position where the moving tray 33 can move backward, and the lifting body is moved to the position. In this embodiment, a plurality of, for example, six block units 102, 102, 102, 102, 102, 102 are stacked by the stacking means 8, and the lowermost block unit 102 is clamped by the clamping arms 63, 63. After moving to a predetermined position, the machine body 2 is stopped, the elevating body 55 is lowered, the clamping arms 63, 63 are opened, and the stacked blocks 102, 102, 102, 102, 102, 102 can be dropped.

  Then, by using the pair of counter-rotating screw conveyors 21L and 21R, the snow can be smoothly sent to the compression space 28 while preventing the snow and the screws 23L and 23R from rotating together. In addition, the snow block 101 sent out from the carry-out port 6B is cut to a certain size by the cutter blade 56. At this time, the snow block 101 is bent using the height difference H, By inserting the cutter blade 56 into the surface where the tensile stress is generated, it can be cut smoothly. Further, the generated rectangular block unit 102 is lifted while being held by the holding arms 63 and 63 from the side surface, and is then superimposed on the generated block unit 102. The clamping arms 63, 63 lower the block unit 102 to release the holding state, clamp the block unit 102 on the moving tray 33, lift it, repeat this operation, and stack the block unit 102 in about six stages.
