Description

Technical Field

[0001] The utility model relates to the field of land surveying equipment, in particular to a fixed-point marking device for land surveying. Background Art

[0002] A search of the patent document with publication number CN221099717U shows that the patent document opens a manual valve, and when the walking wheel rotates one circle, the walking wheel cooperates with the synchronous shaft, synchronous belt, and auxiliary wheel to synchronously rotate the turntable one circle. When the ink fountain of the turntable faces upward, it receives the pigment ink output downward from the ink cylinder. When the turntable subsequently rotates with the ink fountain facing downward, that is, when the ink fountain is just aligned with the ink outlet, the pigment ink is output to the land, forming colored marking dots. The turntable is continuously rotated to leave a row of colored marking dots on the land with an interval of 2.5 meters. The operation is simple and the workload is greatly reduced.

[0003] This patent document outputs pigment ink onto the land, forming colored marking dots. Most of the marking dots fall on the surface soil. Wind-blown soil or people stepping on it will cause the clarity and durability of the marking dots to decrease, affecting subsequent review and construction. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed-point marking device for land surveying in order to solve the above-mentioned problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A fixed point marking device for land surveying, comprising a rotating shaft, a wheel fixed to the rear side of the rotating shaft, a roller sleeved on the middle of the rotating shaft, a handle fixed to one side of the roller, and a marking mechanism;

[0007] The marking mechanism includes a spiral arc plate, which is fixed on the front side of the rotating shaft. A push rod is slidably connected to the top of the spiral arc plate. An ink cartridge is fixed on the front side of the push rod. A rotating ball is provided at the bottom of the ink cartridge. A spring is provided on the top of the rotating ball. A thorn cone for penetrating into the ground is fixed at the bottom of the rotating ball.

[0008] Preferably, a support rod is fixed on the top of the sleeve roller, and a slide groove cooperating with the push rod is fixed on the front side of the support rod.

[0009] Preferably, a plug cover is plugged into the top of the ink cartridge.

[0010] Preferably, the bottom of the ink cartridge is connected to a limiting groove for limiting the moving range of the rotating ball.

[0011] Preferably, the upper end of the spring is fixed to the top of the limiting groove, and the lower end of the spring is fixed to the top of the rotating ball.

[0012] Preferably, a connecting block is fixed between the front side of the push rod and the outer wall of the ink cartridge.

[0013] Compared with the existing technology, the beneficial effects are as follows: the spiral arc plate is driven to rotate in the clockwise direction by the rotation of the rotating shaft, thereby driving the push rod and the ink cartridge to move upward and then fall quickly. The rapid fall of the ink cartridge allows the thorn cone to penetrate deep into the ground. After the thorn cone contacts the ground, the rotating ball is pushed upward, and then the ink in the ink cartridge flows out from the outside of the rotating ball, and then enters deep into the ground along the thorn cone, making the ink mark not easily damaged, increasing clarity and durability, and facilitating subsequent review and smooth construction.

[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-10 As shown, a fixed point marking device for land surveying includes a rotating shaft 1, a wheel 2 is fixed to the rear side of the rotating shaft 1, a roller 3 is sleeved on the middle part of the rotating shaft 1, a handle 4 is fixed to one side of the roller 3, and also includes a marking mechanism 5.

[0030] In this embodiment, the marking mechanism 5 includes a spiral arc plate 501, which is fixed to the front side of the rotating shaft 1. A push rod 503 is slidably connected to the top of the spiral arc plate 501. An ink cartridge 504 is fixed to the front side of the push rod 503. A rotating ball 506 is provided at the bottom of the ink cartridge 504. A spring 507 is provided at the top of the rotating ball 506. A spike 508 for penetrating the soil is fixed at the bottom of the rotating ball 506. The handle 4 pushes the sleeve roller 3 and the rotating shaft 1 from one side to the other, thereby driving the wheel 2 to convert the linear motion into rotational motion, thereby driving the rotating shaft 1 to rotate. One rotation of the wheel 2 is equivalent to the straight line traveled. The linear distance is the circumference of the wheel 2. The rotation of the rotating shaft 1 drives the spiral arc plate 501 to rotate in the clockwise direction, thereby driving the push rod 503 and the ink cylinder 504 to move upward and then fall rapidly. The rapid fall of the ink cylinder 504 allows the thorn cone 508 to penetrate deep into the soil. After the thorn cone 508 contacts the soil, it pushes the rotating ball 506 upward, and then the ink in the ink cylinder 504 flows out from the outside of the rotating ball 506, and enters deep into the soil along the thorn cone 508. Continuously pushing this device causes the wheel 2 and the spiral arc plate 501 to rotate continuously, thereby leaving a row of marking points on the soil with an interval of the circumference of the wheel 2.

[0031] In this embodiment: a support rod 502 is fixed on the top of the sleeve roller 3, and a slide groove cooperating with the push rod 503 is fixed on the front side of the support rod 502. The slide groove on the front side of the support rod 502 limits the moving range of the push rod 503 so that the push rod 503 moves in the vertical direction.

[0032] In this embodiment: a plug cover 505 is inserted into the top of the ink cartridge 504, and a limit groove is connected to the bottom of the ink cartridge 504 for limiting the moving range of the rotating ball 506. The ink cartridge 504 is opened through the plug cover 505 to replenish ink, and the moving range of the rotating ball 506 is controlled by the limit groove to avoid loss.

[0033] In this embodiment: the upper end of the spring 507 is fixed to the top of the limit groove, and the lower end of the spring 507 is fixed to the top of the rotating ball 506. The compression and rebound of the spring 507 make the rotating ball 506 move in the limit groove, thereby controlling the inflow and outflow of ink in the ink cartridge 504.

[0034] In this embodiment, a connecting block is fixed between the front side of the push rod 503 and the outer wall of the ink cartridge 504 , and the connecting block enables the push rod 503 to move along the vertical direction while driving the ink cartridge 504 to move.

[0035] Working principle: Before measurement, pull out the plug cover 505 from the top of the ink tank 504, fill the ink into the ink tank 504, and then insert the plug cover 505 into the top of the ink tank 504. The staff pushes the handle 4 to make the roller 3 and the rotating shaft 1 move from one side to the other side. The rotating shaft 1 drives the wheel 2 to convert the linear motion into rotational motion, thereby driving the rotating shaft 1 to rotate clockwise. The linear distance traveled by the wheel 2 is equivalent to the circumference of the wheel 2. The clockwise rotation of the rotating shaft 1 drives the spiral arc plate 501 to rotate in the clockwise direction. During the rotation of the spiral arc plate 501, the push rod 503 is pushed upward. The push rod 503 moves upward in the vertical direction in the slide groove. The push rod 503 drives the ink tank 504 to move upward. When the wheel 2 and the rotating shaft 1 rotate one circle, the push rod 503 falls quickly from the highest point of the spiral arc plate 501 to The spiral arc plate 501 reaches the lowest point. At this time, the push rod 503 drives the ink cartridge 504 to fall quickly, so that the spike cone 508 is inserted deep into the ground. After the spike cone 508 contacts the ground, it pushes the rotating ball 506 upward. The rotating ball 506 moves upward to leak out the gap, so that the ink in the ink cartridge 504 flows out from the outside of the rotating ball 506. The ink enters the deep ground along the spike cone 508 and continues to push the wheel 2 to rotate. During the continued rotation of the spiral arc plate 501, it pushes the push rod 503 upward and drives the ink cartridge 504 to move upward, so that the spike cone 508 is separated from the ground. The spring 507 rebounds and causes the rotating ball 506 to move downward in the limit groove, blocking the limit groove. The ink no longer flows down, and the device is continuously pushed to make the wheel 2 and the spiral arc plate 501 continue to rotate, thereby leaving a row of marking points on the ground with a spacing of the circumference of the wheel 2.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
