[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 In an embodiment of the utility model, a line drawing device for land planning measurement includes a measuring wheel 1, the axis of which is cooperatively connected with an input shaft of a counter 2; the counter 2 is mounted on a fixed plate 3, and two supporting ribs 7 are provided on the fixed plate 3; an ash hopper 9 is also provided at the upper end of the supporting rib 7; a drop pipe 10 is connected to the bottom of the ash hopper 9.

[0028] By adopting the above technical solution, the land measurement is realized by using the measuring wheel 1. Since the circumference of the measuring wheel 1 is fixed, a certain number of meters can be measured with each rotation. The measuring wheel 1 and the counter 2 are coaxially arranged. With each rotation of the measuring wheel 1, the counter 2 jumps a number. The number displayed by the counter 2 is used to judge the number of rotations of the measuring wheel 1, thereby realizing the land measurement.

[0029] The ash hopper 9 is filled with lime, and the lime falls down along the drop pipe 10, so that it can be used to draw lines when measuring the land.

[0030] In this embodiment, the outer side of the fixed plate 3 is also movably connected to a side support 4, and a fixed tube 5 is fixed to the side of the fixed plate 3 where the counter 2 is installed; a telescopic handle 6 is installed in the fixed tube 5 and is fixed by a quick buckle.

[0031] By adopting the above technical solution and setting the telescopic handle 6, the telescopic degree of the telescopic handle 6 and the fixed tube 5 can be adjusted, thereby meeting the usage requirements of workers of different heights.

[0032] The provision of the side support 4 facilitates the support and docking of the device when not in use.

[0033] In this embodiment, one end of the support rib 7 is fixed to the fixing plate 3, and the other end extends to the top of the measuring wheel 1, and is arranged in a U shape; two C-shaped grooves are provided at the bottom of the mounting plate 8, and are buckled on the two support ribs 7, and two clamps 11 for pressing and fixing the support ribs 7 are also connected at the bottom of the mounting plate 8.

[0034] By adopting the above technical solution, the structure of the equipment is simplified, making the measuring and drawing device lighter and easier for operators to operate.

[0035] In this embodiment, the ash hopper 9 is fixed on the mounting plate 8, and a through hole is opened in the middle of the mounting plate 8 to facilitate the passage of the drop tube 10; a plurality of ribs are arranged around the ash hopper 9, and the ribs are fixedly connected to the ash hopper 9 and the mounting plate 8.

[0036] By using the above technical solution, the arrangement of the ribs increases the stability between the ash hopper 9 and the mounting plate 8, and improves the bearing capacity of the ash hopper 9.

[0037] In this embodiment, a positioning member 13 is further provided at one end of the two supporting ribs 7 located at the top of the measuring wheel 1 ; both ends of the positioning member 13 are clamped and fixed to the supporting ribs 7 .

[0038] By adopting the above technical solution and setting the positioning member 13, the upper end of the blanking pipe 10 is positioned to prevent the blanking pipe 10 from rubbing against the measuring wheel 1, thereby ensuring the normal blanking of the lime.

[0039] In this embodiment, a plug plate 12 for controlling the on / off of white ash is further provided at the bottom of the ash hopper 9. After the plug plate 12 is pulled outward, the white ash in the ash hopper 9 will enter the drop pipe 10, thereby facilitating the drawing of lines during the measurement process. When there is no need to draw lines, the plug plate 12 can be pushed in, which is very convenient to operate.

[0040] The working principle of the utility model is: when in use, first open the side support 4, adjust the telescopic handle 6 and the telescopic degree of the fixed tube 5; then hold the telescopic handle 6 to push the device forward; use the measuring wheel 1 to measure the land, because the circumference of the measuring wheel 1 is fixed, each rotation can measure a certain number of meters; the measuring wheel 1 and the counter 2 are coaxially arranged, each time the measuring wheel 1 rotates a circle, the counter 2 jumps a number, and the number displayed by the counter 2 is used to judge the number of rotations of the measuring wheel 1, thereby realizing the measurement of the land.

[0041] The ash hopper 9 is filled with lime. When it is necessary to draw lines, the plug plate 12 is pulled outward, and the lime in the ash hopper 9 enters the drop pipe 10, and then the lime falls to the ground along the drop pipe 10, so that lines can be drawn when measuring the land; when it is not necessary to draw lines, the plug plate 12 can be pushed in, which is very convenient to operate.
