Description

Technical Field

[0001] This utility model relates to the field of line marking device technology, specifically a land measurement and line marking device. Background Technology

[0002] The land surveying and marking device, through advanced electronic technology and geographic information system, can collect information such as the length and width of land in real time, and calculate the area through built-in algorithms, which greatly improves the accuracy of measurement and saves manpower and time costs. The device is designed with a protective shell and cleaning parts to protect the measuring instrument body and maintain the clarity of the measurement screen, thereby improving the efficiency of measurement. In addition, the push-pull handle and wheels of the device are designed to facilitate the movement and use of operators, improving the convenience of operation.

[0003] As disclosed in the authorization announcement number CN222235559U, a land demarcation device includes a vertical pole and a telescopic pole arranged opposite each other on the left and right. The telescopic pole is located inside the vertical pole and can be extended and retracted vertically. A circular support plate is sleeved at the bottom end of the vertical pole. A limit plate is welded to the top end of the telescopic pole. A sleeve is sleeved at the top end of the telescopic pole and above the limit plate. The sleeve is rotatably connected to the top end of the telescopic pole. A connecting block is welded to the sleeve. A rotating handle is rotatably connected to the connecting block. A wheel is fixed on the rotating handle. A nylon rope is sleeved on the wheel. A pull rope is tied to the nylon rope. A plastic funnel is connected to the bottom end of the pull rope. A screw cap is threaded to the bottom end of the plastic funnel.

[0004] Although it achieves the goal of inserting uprights at both ends of the line to be marked, with circular support plates at the bottom of the uprights supporting the ground to prevent the uprights from swaying, and telescopic rods that can extend and retract within the uprights to effectively reduce storage space, during line marking, a nylon rope is connected to a wheel on the outside of the sleeve, and a plastic funnel is connected to the nylon rope. Rotating the handle moves the plastic funnel left and right between the two uprights to discharge ash, making it more convenient to use. The entire line marking process is suspended in the air and is not affected by uneven ground. Moreover, the center of gravity of the plastic funnel is very low after it is filled, so it will not wobble at all when moving. When moving and discharging at the same time, the rope structure of the connections results in very little wind resistance compared to existing technologies, thus making it less affected by environmental factors. At the same time, all parts are common parts, and the connections are made by threading, welding or binding, without the need for additional mold manufacturing, resulting in lower costs.

[0005] However, this does not solve the problem that existing marking devices of this type are generally not conducive to conveniently switching between different powders for marking, nor are they convenient for multi-stage rotation adjustment of position for marking, which affects the working range and efficiency of the marking device. Utility Model Content

[0006] The purpose of this utility model is to provide a land surveying and marking device to solve the problems mentioned in the background art, such as the inconvenience of switching between different powders for marking, the inconvenience of multi-level rotation adjustment for marking, which affect the working range and efficiency of the marking device.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A land surveying and marking device includes a frame and a longitudinal screw moving assembly. The longitudinal screw moving assembly is externally mounted on the frame, and a threaded block is internally mounted on the frame. Two sets of electric wheels are symmetrically and movably mounted on both sides of the frame. A curved arm is mounted on one side of the longitudinal screw moving assembly, and a support block is externally mounted on the curved arm. A discharge pipe is internally mounted on the support block. A rotating cylinder is externally mounted on the longitudinal screw moving assembly, and five equally spaced funnels are externally mounted on the rotating cylinder. A C-shaped frame is mounted on the other side of the longitudinal screw moving assembly, and an adapter sleeve is internally mounted on the C-shaped frame. The C-shaped frame extends to its exterior. A hollow column is movably installed inside the adapter sleeve, and the hollow column extends into the interior of the rotating cylinder and connects to it. A servo motor is installed on the side wall of the C-shaped frame, and a small gear is installed at the output end of the servo motor. A large gear is fitted on the surface of the hollow column, and the small gear meshes with the large gear. Five sets of storage troughs with equal spacing are arranged inside the rotating cylinder. A second solenoid valve is installed at the top of each storage trough, and the second solenoid valve passes through the rotating cylinder and connects to the funnel. A first solenoid valve is installed at the bottom of each storage trough, and the first solenoid valve extends into the interior of the hollow column and connects to it.

[0009] Optionally, a power motor is mounted on the side wall of the frame, and a threaded rod is mounted on the output end of the power motor, the threaded rod extending into the interior of the frame and movably connected thereto.

[0010] Optionally, the threaded rod is threadedly connected to the threaded block, and a rotating shaft is installed at the bottom end of the longitudinal lead screw moving assembly.

[0011] Optionally, the rotating shaft extends to the top of the threaded block and is movably connected thereto, and a stepper motor is mounted on the top of the threaded block outside the rotating shaft.

[0012] Optionally, a worm gear is installed at the output end of the stepper motor, and a worm wheel is fitted on the surface of the rotating shaft, with the worm gear connected to the worm wheel.

[0013] Optionally, an electric pump is installed on one side of the bent arm, and a first hose is installed on the side of the adapter sleeve near the longitudinal lead screw moving assembly.

[0014] Optionally, the side of the first hose away from the adapter sleeve is connected to the electric pump, and the output end of the electric pump is equipped with a second hose.

[0015] Optionally, the side of the second hose away from the electric pump is connected to the discharge pipe, and a variable frequency motor is installed on the other side of the bent arm.

[0016] Optionally, the output end of the variable frequency motor is equipped with a rotating shaft, which extends through the curved arm to the outside and connects to the support block.

[0017] Optionally, the rotating shaft is movably connected to the bent arm, and the rotating shaft is fixedly connected to the support block.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the scribing device not only realizes the convenient switching of different powders for scribing, but also facilitates multi-level rotation adjustment of position for scribing, increases the working range of the scribing device, and improves the working efficiency of the scribing device.

[0019] Multiple sets of electric wheels are activated, moving the land surveying and marking device to the working area. The second solenoid valve is opened, allowing different powders to enter multiple storage troughs through multiple funnels. The first solenoid valve is opened, allowing the powder from the storage troughs to enter the hollow column. The electric pump, supported by the curved arm, pumps the powder from the hollow column through the adapter sleeve and the first flexible hose to the discharge pipe, facilitating convenient land marking. When different powders are needed, the servo motor drives the pinion to rotate, which in turn drives the large gear, which in turn drives the hollow column, rotating cylinder, storage troughs, second solenoid valve, funnels, and first solenoid valve to rotate, bringing the required powder to the top. This allows for convenient switching between different powders for marking, making the marking device easy to use.

[0020] When marking lines requires movement to a certain position, the power motor drives the threaded rod to rotate, which in turn moves the threaded block. The threaded block then moves the rotating shaft, longitudinal lead screw moving assembly, bent arm, support block, and discharge pipe to a certain position. The longitudinal lead screw moving assembly further moves the bent arm, support block, and discharge pipe to a certain position. When rotation is required, the stepper motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel then rotates the rotating shaft, longitudinal lead screw moving assembly, bent arm, support block, and discharge pipe to a certain angle for marking. When tilting at a certain angle is required, the frequency converter motor drives the rotating shaft to rotate, which in turn rotates the support block and discharge pipe to tilt at a certain angle for marking. This facilitates multi-stage rotation adjustment for marking, increasing the working range and improving the efficiency of the marking device. Attached Figure Description

The longitudinal screw moving assembly 2 is disposed on the outside of the frame 1, and a threaded block 21 is disposed inside the frame 1. Two sets of electric wheels 7 are symmetrically and movably mounted on both sides of the frame 1. A bent arm 3 is mounted on one side of the longitudinal screw moving assembly 2, and a support block 6 is disposed on the outside of the bent arm 3.

The first solenoid valve 9 extends into the interior of the hollow column 16 and connects to it.

[0038] When using the land surveying and marking device, multiple sets of electric wheels 7 are turned on to move the device to the working area. The second solenoid valve 10 is opened, allowing different powders to enter multiple storage tanks 29 through multiple funnels 5. The first solenoid valve 9 is opened, allowing the powder inside the storage tanks 29 to enter the hollow column 16. The electric pump 25 is turned on, and supported by the curved arm 3, it pumps the powder inside the hollow column 16 through the adapter sleeve 12 and the first hose 24 to the discharge pipe 8 for easy and convenient land marking. Different powders can be used as needed. When the servo motor 13 is turned on, under the support of the C-frame 11, the servo motor 13 drives the pinion 14 to rotate. Under the meshing of the pinion 14 and the large gear 15, the pinion 14 drives the large gear 15 to rotate. The large gear 15 drives the hollow column 16, the rotating cylinder 4, the storage tank 29, the second solenoid valve 10, the funnel 5, and the first solenoid valve 9 to rotate, so that the required powder is rotated to the top, which facilitates the convenient switching of different powders for marking. This realizes the convenient switching of different powders for marking by the marking device, and improves the convenience of the marking device for marking different powders.

[0039] A power motor 22 is installed on the side wall of the frame 1. A threaded rod 23 is installed at the output end of the power motor 22. The threaded rod 23 extends into the interior of the frame 1 and is movably connected thereto. The threaded rod 23 is threadedly connected to the threaded block 21.

The side of the second hose 26 away from the electric pump 25 is connected to the discharge pipe 8. The other side of the bent arm 3 is equipped with a variable frequency motor 27.

[0043] The output end of the variable frequency motor 27 is equipped with a rotating shaft 28. The rotating shaft 28 extends through the curved arm 3 to its outside and is connected to the support block 6. The rotating shaft 28 is movably connected to the curved arm 3 and is fixedly connected to the support block 6.

[0044] When it is necessary to move the device to a certain position for marking, the power motor 22 is turned on. Supported by the frame 1, the power motor 22 drives the threaded rod 23 to rotate. With the threaded connection between the threaded rod 23 and the threaded block 21, the threaded rod 23 drives the threaded block 21 to move. The threaded block 21 drives the rotating shaft 20, the longitudinal lead screw moving assembly 2, the bent arm 3, the support block 6, and the discharge pipe 8 to move to a certain position. The longitudinal lead screw moving assembly 2 is then turned on. Supported by the rotating shaft 20, the longitudinal lead screw moving assembly 2 drives the bent arm 3, the support block 6, and the discharge pipe 8 to move to a certain position. When rotation is required, the stepper motor 17 is turned on. Supported by the threaded block 21, the stepper motor 17 drives the worm gear.

The second solenoid valve 10 is opened, allowing different powders to enter the interior of multiple storage tanks 29 through multiple funnels 5. The first solenoid valve 9 is opened, allowing the powder inside the storage tanks 29 to enter the interior of the hollow column 16. The electric pump 25 transports the powder inside the hollow column 16 through the adapter sleeve 12 and the first hose 24 to the discharge pipe 8 for dropping, facilitating convenient marking of the land. When different powders are needed, the servo motor 13 drives the pinion 14 to rotate, which in turn drives the large gear 15 to rotate. The large gear 15 drives the hollow column 16, rotating cylinder 4, storage tanks 29, second solenoid valve 10, funnels 5, and first solenoid valve 9 to rotate, so that the required powder is rotated to the top, facilitating convenient switching between different powders for marking. When a line needs to be moved to a certain position for marking, the power motor 22 drives the threaded rod 23 to rotate, which in turn moves the threaded block 21. The threaded block 21 then moves the rotating shaft 20, the longitudinal lead screw moving assembly 2, the bent arm 3, the support block 6, and the discharge pipe 8 to a certain position. The longitudinal lead screw moving assembly 2 then moves the bent arm 3, the support block 6, and the discharge pipe 8 to a certain position. When rotation is required, the stepper motor 17 drives the worm gear 18 to rotate, which in turn drives the worm wheel 19 to rotate. The worm wheel 19 then rotates the rotating shaft 20, the longitudinal lead screw moving assembly 2, the bent arm 3, the support block 6, and the discharge pipe 8 to a certain angle for marking. When tilting at a certain angle is required, the frequency converter motor 27 drives the rotating shaft 28 to rotate, which in turn rotates the support block 6 and the discharge pipe 8 to tilt at a certain angle for marking. This allows for multi-stage rotation adjustment for marking, thus completing the operation of the marking device.
