Description

Technical Field

[0001] This utility model belongs to the field of laser measuring instrument technology, specifically relating to a multifunctional laser measuring instrument for pear orchard establishment. Background Technology

[0002] Laser rangefinders are instruments that measure the distance to a target by modulating a laser with a specific parameter. The range of a laser rangefinder is 3.5-5000 meters. Based on the measurement method, they are divided into phase-based rangefinders and pulse-based rangefinders. A pulse-based laser rangefinder emits a single or a series of short pulsed laser beams towards the target. A photoelectric element receives the laser beam reflected from the target, and a timer measures the time from emission to reception to calculate the distance from the observer to the target. In pear orchards, laser rangefinders are used to measure the distance between adjacent pear trees to maintain consistency and standardization in orchard establishment.

[0003] Commonly used laser rangefinders can only measure distance in one direction. However, the exact location of the pear tree requires both front-to-back and left-to-right measurements to pinpoint it accurately. Ordinary rangefinders require measuring in one direction first, then in the other, which is inefficient and prone to measurement errors. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: the measuring end of the first laser ranging sensor is aligned with the pear tree at the front to determine the distance between the two pear trees in front and behind.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, a multifunctional laser measuring instrument for pear orchard establishment includes a ground spike 1 and an installation component 2. The installation component 2 is fixedly connected to the top of the ground spike 1. A support component 3 is rotatably connected to the side wall of the ground spike 1. A first laser ranging sensor 4 and a second laser ranging sensor 5 are fixedly installed on the top of the installation component 2 and the top of the support component 3, respectively. A scale line 6 is provided on the top of the installation component 2 to indicate the angle between the first laser ranging sensor 4 and the second laser ranging sensor 5.

[0021] Based on the above structure, when in use, the measuring end of the first laser rangefinder 4 is aligned with the pear tree in front to determine the distance between the two pear trees in front and behind. The angle between the first laser rangefinder 4 and the second laser rangefinder 5 is adjusted according to the angle between the two rows of pear trees. The distance between the left and right adjacent pear trees is measured by the second laser rangefinder 5, so that the position of the pear tree can be accurately located.

[0022] like Figure 2 As shown, a limiting plate 11 is fixedly connected to the top of the spike 1.

[0023] Based on the above structure, the limiting plate 11 can prevent the ground spike 1 from being inserted too deeply downwards.

[0024] like Figure 3 and 4 As shown, the installation component 2 includes a disc 21 fixedly connected to the top of the spike 1. The side wall of the disc 21 is provided with an annular groove 22. The top and bottom of the annular groove 22 are provided with two concentrically distributed annular limiting grooves 23. The edge of the top of the disc 21 is provided with an annular positioning groove 24. The support component 3 includes an arc-shaped slider 31. The arc-shaped slider 31 is rotatably connected to the inside of the annular groove 22. The top and bottom of the arc-shaped slider 31 are provided with two concentrically distributed arc-shaped sliders 32. The arc-shaped sliders 32 are rotatably connected to the inside of the corresponding annular limiting grooves 23. An L-shaped support plate 33 is fixedly connected to one side of the arc-shaped slider 31. The second laser rangefinder 5 is fixedly installed on the top of the L-shaped support plate 33. The top of the L-shaped support plate 33 is fixedly connected to a top plate 34. The top of the top plate 34 is fixedly connected to a threaded cylinder 35. A screw 36 is threadedly connected inside the threaded cylinder 35. A handle 37 is fixedly connected to the top of the screw 36. A pointer 38 is fixedly connected to one side of the top plate 34.

[0025] According to the above structure, during use, the distance between the front end of the first laser rangefinder 4 and the front end of the second laser rangefinder 5 and the axis of the ground spike 1 is fixed. The first laser rangefinder 4 is aligned with the pear tree at the front end. Then, by rotating the L-shaped support plate 33, the arc-shaped slider 31 is driven to rotate along the annular groove 22, thereby adjusting the included angle between the first laser rangefinder 4 and the second laser rangefinder 5. After the adjustment is completed, the screw 36 inside the threaded cylinder 35 is tightened so that the bottom end of the screw 36 is pressed into the annular positioning groove 24, thereby fixing the angle of the second laser rangefinder 5. The pointer 38 can accurately indicate the angle of the second laser rangefinder 5, and the arc-shaped slider 32 can improve the stability of the rotation of the arc-shaped slider 31.

[0026] like Figure 2 As shown, a pressure rod 7 is fixedly connected to the middle of the top of the mounting component 2, and a pressure plate 71 is fixedly connected to the top of the pressure rod 7.

[0027] Based on the above structure, when the ground spike 1 is pulled and pressed, the pressure plate 71 is used for pulling and pressing, which facilitates the installation and disassembly of this measuring instrument.

[0028] The working principle of this utility model is as follows: In use, the measuring end of the first laser rangefinder 4 is aligned with the pear tree at the front to determine the distance between the two pear trees. The angle between the first laser rangefinder 4 and the second laser rangefinder 5 is adjusted according to the angle between the two rows of pear trees. The second laser rangefinder 5 measures the distance between adjacent pear trees on the left and right, thus accurately locating the pear tree's position. The limiting plate 11 prevents the ground spike 1 from being inserted excessively downwards. In use, the distance between the front end of the first laser rangefinder 4 and the front end of the second laser rangefinder 5 and the axis of the ground spike 1 is fixed. The first laser rangefinder 4 is aligned with the front end of the pear tree at the front... The pear tree is then rotated. The L-shaped support plate 33 drives the arc-shaped slider 31 to rotate along the annular groove 22, thereby adjusting the included angle between the first laser rangefinder 4 and the second laser rangefinder 5. After adjustment, the screw 36 inside the threaded cylinder 35 is tightened so that the bottom end of the screw 36 is pressed into the annular positioning groove 24, thereby fixing the angle of the second laser rangefinder 5. The pointer 38 can accurately indicate the angle of the second laser rangefinder 5. The arc-shaped slider 32 can improve the stability of the rotation of the arc-shaped slider 31. When pulling and pressing the ground spike 1, the pressure plate 71 is used for pulling and pressing, which facilitates the installation and disassembly of this measuring instrument.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
