At this time, the lateral movement of the input half gear 721 will not be hindered, and the path control shaft 74 uses three rotation path grooves 741 to make the contact ball protrusion 731 stay at three different positions to achieve in-situ rotation. The three rotation path grooves 741 are connected by spiral path grooves 742. Once the contact ball protrusion 731 enters the spiral path groove 742, it will continue to be pushed by the inner wall of the spiral path groove 742 and move to the next rotation path groove 741.

During the rotation of the stroke input gear 81, the stroke output gear 83 is engaged and driven to rotate. The stroke output gear 83 outputs the rotation to the pulley structure formed by the input cone column 831, the cone column belt 832 and the output cone column 8311, and the transmission ratio between the input cone column 831 and the output cone column 8311 can be adjusted by adjusting the position of the cone column belt 832, and the rotation is continued to be transmitted to the mobile drive shaft 86 through the stroke pulley 85 and the stroke belt 851. The moving drive shaft 86 rotates and drives the driving wheel 861 to move the entire device forward. The stroke input gear 81 simultaneously drives the driven lever arm 82 to rotate. Both driven lever arms 82 are equipped with contact bosses 822 in opposite directions. When the contact bosses 822 contact the driven lever block 73, it will be pushed to one side. At this time, if the contact ball protrusion 731 is in the spiral path groove 742, it will be pushed in. The driven lever block 73 moves to one side. If it is not in the spiral path groove 742, the force storage spring 821 will store the force, and when the contact ball protrusion 731 is in the spiral path groove 742, it will be released and pushed in. At this time, the stroke input gear 81 drives the driven lever arm 82 to rotate. The two driven lever arms 82 are both equipped with contact bosses 822 in opposite directions. When the contact bosses 822 contact the driven lever block 73, it will be pushed to one side. The input gear 81 does not mesh with the input half gear 721 and stops rotating, achieving the effect of timing the driven shift block 73 to control the meshing time. When the driven shift block 73 returns to the stroke input gear 81 again, the opposite driven shift arm 82 on the other side will shift the driven shift block 73 to the other side. The driven shift arms 82 on both sides are used alternately to shift the driven shift block 73 to both sides in turn. Since the rotation time of the stroke input gear 81 is the same each time, the transmission ratio between the input cone column 831 and the output cone column 8311 is changed to change the forward distance of the device each time it moves forward, thereby controlling the marking interval each time.

[0029] The stroke control mechanism 9 includes an inner input gear 91, which is rotatably connected to the inner surface of the mounting housing 5, one end of the inner input gear 91 is fixedly connected to an inner input pulley 911, an inner belt 9111 is sleeved on the outer surface of the inner input pulley 911, and an inner output pulley 9112 is sleeved on the other side surface of the inner belt 9111, one end of the inner input pulley 911 is fixedly connected to the forward shaft 92, and a reverse bevel gear set 921 is installed on the other end of the inner input pulley 911, and a side input pulley 912 is rotatably connected to the inner surface of the device housing 1, and the outer surface of the side input pulley 912 is sleeved on the outer surface of the side input pulley 912.

Through the setting of the stroke control mechanism 9, during use, the stroke control mechanism 9 is symmetrically distributed on both sides of the structural base The same, part of the rotation in the same direction, will drive the rotating input bevel gear 6411 to rotate through the inner input pulley 911, so that the rotating input bevel gear 6411 on both sides has the same direction, but one side is connected to the inner input pulley 911 and the side input pulley 912 by the positive shaft 92, and the other side is connected to the inner input pulley 911 and the side input pulley 912 by the reverse bevel gear set 921, so that the clockwise and reverse screw rods 93 can be forward and reversed, so that the reciprocating seat 94 can push the driven shift block 73 to different sides in turn, and when the rotating input bevel gear 6411 on one side rotates, it will be reversed twice by the action of the bevel gears, so that the clockwise and reverse screw rods 93 can be forward and reversed. The directions of the output pulleys 9122 on both sides of the screw rod 93 are the same. Assuming that all the pulleys on the side of the forward shaft 92 are rotating forward at this time, the clockwise and counterclockwise screw rods 93 are also rotating forward, and the rotating input bevel tooth 6411 on one side of the counter-bevel gear set 921 is reversed, and the rotation continues to be transmitted to the inner input pulley 911 through the inner belt 9111. Under the reversing action of the counter-bevel gear set 921, it turns back to forward rotation again, and the side output pulley 9122 on the side of the counter-bevel gear set 921 rotates forward, while the side output pulley 9122 on the side of the forward shaft 92 originally rotates forward. In this way, the directions of the side output pulleys 9122 on both sides of the clockwise and counterclockwise screw rods 93 are always the same.

[0030] The inner input pulley 911 is meshed with the input half gear 721. The number of the inner input gear 91, the inner input pulley 911, the inner belt 9111 and the inner output pulley 9112 are all two, and the two inner input gears 91, the two inner input pulleys 911, the two inner belts 9111 and the two inner output pulleys 9112 are symmetrically distributed with the central axis of the mounting shell 5 as the symmetry axis, and the two inner output pulleys 9112 are respectively fixedly connected to the two rotating input bevel teeth 6411, and the inner output pulley 9112 is rotationally connected to the inner surface of the inner mounting seat 4. The positive shaft 92 connects the inner output pulley 9112 and the side input pulley 912 on one side, and the reverse bevel gear set 921 connects the inner output pulley 9112 and the side input pulley 912 on the other side. There are two pulleys 912, two side belts 9121 and two side output pulleys 9122, and the two side input pulleys 912, the two side belts 9121 and the two side output pulleys 9122 are symmetrically distributed with the central axis of the mounting housing 5 as the axis of symmetry. The reverse bevel gear set 921 is composed of three bevel gears meshing in sequence. The two ends of the clockwise and counterclockwise screw rods 93 are fixedly connected to the side output pulleys 9122 on both sides respectively. The fixed push block 941 and the movable push block 942 are both slidably connected to the driven shift block 73. The extrusion rod 9421 penetrates the movable push block 942 and is slidably connected to the outer surface of the reciprocating seat 94. The extrusion rod 9421 is slidably connected to the inner surface of the stroke adjustment groove 52. The stroke adjustment groove 52 supports and externally controls the extrusion rod 9421. , the driven shifting arm 82 shifts the driven shifting block 73 to one side. Assuming that it is shifted to the side of the reverse bevel gear set 921 at this time, the internal input gear 91 on this side meshes with the input half gear 721, and the movable push block 942 is away from the driven shifting block 73 at this time. The internal input gear 91 on this side will firstly transmit the rotation to the internal output pulley 9112 through the action of the internal input pulley 9111 and the internal belt 9111, and the internal output pulley 9112 drives the rotating input bevel gear 6411 on this side to rotate, and drives the rotating output bevel gears 642 on both sides to rotate and turn in opposite directions through the double-headed bevel gear 641. The opening and closing screw rods 643 on both sides turn in opposite directions and drive the movable spray gun seat 65 to move away from each other, and perform horizontal line spraying in the process of moving away. At the same time, the internal input gear 91 on this side drives the reverse bevel gear set 921 to move away from each other. The bevel gear set 921 rotates, and the output direction is opposite through the action of three bevel gears meshing in sequence, and the reverse rotation is transmitted to the pulley structure composed of the side input pulley 912, the side belt 9121 and the side output pulley 9122, and the clockwise and counterclockwise screw rods 93 rotate in the opposite direction. The clockwise and counterclockwise screw rods 93 drive the movable push block 942 on the reciprocating seat 94 to move toward the direction of the driven shift block 73, and push it after contact, and similarly push the contact ball protrusion 731 into the spiral path groove 742. The driven shift block 73 moves to the stroke input gear 81 again. After the entire device moves forward a certain distance, the driven shift block 73 is pushed to the internal input gear 91 on one side of the forward shaft 92. The internal input gear 91 on the side of the forward shaft 92 drives the rotating input bevel gear 6411 on the other side to rotate.The double-headed bevel gear 641 reverses and drives the rotating output bevel gear 642 to rotate. The rotating output bevel gears 642 on both sides are opposite to the previous direction. The opening and closing screw rod 643 drives the movable spray gun seat 65 to approach each other. At the same time, the inner input gear 91 on this side drives the side input pulley 912, the side belt 9121 and the side output pulley 9122 to rotate through the forward shaft 92. The clockwise and counterclockwise screw rods 93 rotate forward, and the reciprocating seat 94 drives the fixed push block 941 to move toward the driven shift block 73, and pushes the driven shift block 73 to the stroke input gear 81 again. The movable push block 942 can be moved according to the different positions on the reciprocating seat 94. , change the pushing time, adjust the rotation time of the opening and closing screw rod 643 to control the length of each marking, and form a complete cycle. Each complete cycle includes: the driven block 73 first meshes with the stroke input gear 81 and the entire device moves forward for vertical spraying, the driven block 73 meshes with the inner input gear 91 on one side, and the movable spray gun seat 65 opens outward for horizontal spraying and marking, the driven block 73 meshes with the stroke input gear 81 and continues to move forward, the driven block 73 meshes with the inner input gear 91 on the other side and retracts outward to perform horizontal spraying and marking on one side, so as to control the angle, interval and length of each spraying and marking, and the whole process is carried out automatically. ,
