[0002] The application number is 201921890986.9, and the utility model name is a handheld marking device for field tests. One end of a handheld handle (2) is connected to a push rod (3), and the other end of the push rod is connected to a roller fixing device. Holes (13) for passing through a transverse shaft (6) are respectively opened at the lower end part of a fixing card (5). Threaded structures are arranged at both ends of the transverse shaft. The roller device includes a spherical roller (8) for containing talcum powder. A transverse central through hole (14) is opened inside the spherical roller. The transverse shaft passes through the transverse central through hole. The holes are arranged, and a first nut is adaptively installed on the threaded structures at both ends of the transverse shaft. Powder outlet holes are evenly opened at the longitudinal central position of the spherical roller. Annular protrusions are respectively arranged on both sides of the powder outlet holes. A talcum powder injection port is arranged on the spherical roller, and the talcum powder injection port is opened and closed through a powder injection port cover plate.

All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present utility model belong to the scope of protection of the present utility model.

[0030] As Figure 1-6 shown, an agricultural line marker of the present utility model includes a mounting and fixing frame 1, a drive DC motor 6, a lithium battery 8, a drum, and a circuit part.

[0031] The mounting and fixing frame 1 is composed of a hollow rectangular iron handle, a hollow cylindrical iron pipe, and a U-shaped iron frame. The middle of the iron handle is connected (by welding, screw connection) and fixed to one end of the hollow cylindrical iron pipe, and the other end of the hollow cylindrical iron pipe is installed (by welding, bolt connection) in the middle of the U-shaped iron frame.

[0032] The U-shaped iron frame is composed of two vertical L-shaped iron sheets welded to the two ends of a horizontal L-shaped iron sheet. The length of the L-shaped iron sheet is 0.33 m, the width is 0.025 m, and the height is 0.025 m.

[0033] An I-shaped iron sheet is installed at a position 0.02 m away from the left edge of the U-shaped iron frame. A drive DC motor 6 (12V, 60r / min) is installed on the I-shaped iron sheet, and the field effect transistor 12 is fixed to the I-shaped iron sheet by PMW screws. A 10-tooth driving sprocket 7 is installed on the drive DC motor 6.

[0034] The lithium battery 8 (12V, 11000 mA) is bundled to the L-shaped iron sheet on the right side of the U-shaped iron frame by a self-locking nylon tie (5.0 * 350).

[0035] The drum is composed of a left drawing wheel hub cavity 3 and a right drawing wheel hub cavity 4 which are buckled together and fixed by cross PWM screws. Both the left drawing wheel hub cavity 3 and the right drawing wheel hub cavity 4 are iron basins with a mouth diameter of 26 cm, a bottom diameter of 16 cm, and a height of 8 cm. Holes are drilled every 10 cm on the circumference at the edge of the basin mouth. Horizontal axes are welded on both sides of the bottom center of the two iron basins. Two pedestal bearings 2 are respectively fixed at the ends of the L-shaped iron sheets on both sides of the U-shaped iron frame by hexagon machine screws. The horizontal axes cooperate with the pedestal bearings 2 to fix the two iron basins inside the L-shaped iron sheets on both sides of the U-shaped iron frame. A driving sprocket 5 with 20 teeth is installed on the left iron basin. The driving sprocket 7 is connected to the driving sprocket 5 through a driving chain 10. A basin arm is opened at the mouth of the right iron basin, and the basin arm and the notch are tightly connected by a reverse wire.

[0036] The circuit part is as follows: A switch 9 is installed on the hollow rectangular iron handle of the installation fixing frame 1. One end of the switch 9 is connected to the positive electrode of the lithium battery 8 and the 2nd port of the field effect transistor 11 through a power cord. The other end of the switch 9 is connected to a 100-kilohm resistor 12. The other end of the resistor 12 is connected to the 1st port of the field effect transistor 11.

[0038] Before use, open the basin arm, pull it open with the reverse wire, pull the basin arm outwards, add an appropriate amount of lime powder (magnetic powder), and different types of powdered ash can also be loaded according to needs. Close the basin arm and fasten it with the reverse wire. Turn on the switch, hold the line marker by hand, and when the drum rotates automatically, move forward at a uniform speed in the direction of the line to be drawn. Since there is no need to drive the drum to rotate by friction with the ground, there is no problem of slipping. At the same time, since the drum is driven by a motor, the labor intensity of the user is reduced. After drawing, turn off the switch 11.
