Description

A measuring device for plant height and stalk diameter

technical field

The utility model relates to a measuring device, in particular to a measuring device for plant height and stalk diameter.

Background technique

In disciplines involving plant research such as agronomy and ecology, the average height, maximum height and stem diameter of plants are all basic measurements, so how to perform simple operations in the field environment and accurately collect data is particularly important.

There are two common plant height measuring devices:

One is a measuring rod that can be folded in half. Its overall shape is similar to that of a tower ruler, and a caliper is fixed at the bottom. It sinks into the soil for a certain distance, especially when measuring the herbaceous plants such as sedge and reeds that grow in swamps and other wetlands. The measuring rod is also easy to tilt during use, causing reading errors.

The other is to modify the rangefinder so that it can measure the distance between the device and the top of the herb, the angle between the vertical line of the device and the line between the device and the top of the herb, and the distance between the device and the bottom of the herb. and the angle between the vertical line of the device and the line between the device and the bottom of the herb. Then, the data processing method of surveying is used to calculate the height of plants, so as to achieve fast, accurate and non-damaging measurement of plants. However, this device is suitable for measuring large-scale plant groups, and the measurement of individual plants is more complicated and costly. High and inconvenient to carry in the field.

Utility model content

Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a measuring device for plant height and stalk diameter.

Technical solution: In order to solve the above technical problems, a measuring device for plant height and stalk diameter of the utility model includes a measuring main rod, a measuring sliding rod, a restraint ring and a tip base, and the longitudinal position of the measuring main rod is set There are scales, the top of the measuring main rod is provided with a horizontal bubble device, the bottom of the measuring main rod is a pointed base, and the middle position of the measuring main rod is connected with a horizontal slide bar caliper and a restraint ring that can slide up and down; The bottom of the bar caliper is attached with a slide bar clamp.

In order to enhance the stability of the whole device, the tip base is a cylinder, and there is a spike under the tip base. The spike is inserted into the ground, and the cylinder is fixed on the ground. measurement error.

Preferably, one end of the slide bar clamp is fixed below the slide bar caliper by a spring, the middle position of the slide bar clamp is directly connected to the slide bar caliper, and the other end of the slide bar clamp is against the slide bar caliper.

Preferably, the slide bar caliper is movably connected to the measuring main bar through a first slide bar.

Preferably, the binding ring is movably connected to the measuring main rod through the second sliding rod.

Preferably, one end of the restraint ring is fixed to the second slide bar, the other end of the restraint ring can be snapped into the fixing belt of the second slide bar, and the other end of the restraint ring can also be fixed to the second slide bar by Velcro.

Beneficial effects: the device for measuring plant height and stalk diameter of the utility model can adjust the vertical position of the measuring main rod in real time through the cooperation of the horizontal air bubbler at the top of the measuring main rod and the tip base at the bottom of the measuring main rod. Measurement accuracy, the slide bar caliper can be used to measure the diameter of the stem at the same time. When measuring in the field, a single person can complete all the measurement work, saving time and effort, and measuring accurately. The utility model has the advantages of simple structure and flexible operation.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figures 1 to 5, a plant height and stalk diameter measuring device of the present utility model includes a measuring main rod 1, a measuring slide rod, a restraint ring 6 and a tip base 2, and measures the longitudinal position of the main rod 1 There is a scale on the top of the main measuring rod 1. A horizontal bubbler 7 is provided on the top of the main measuring rod 1. The bottom end of the main measuring rod 1 is a tip base 2. A horizontal slide bar caliper that can slide up and down is connected to the middle position of the main measuring rod 1. 5 and the binding ring 6; the bottom of the slide bar caliper 5 is connected with a slide bar clip 4.

Wherein, the horizontal bubbler 7 is embedded in the top of the measuring main rod 1, which can ensure the verticality of the measuring main rod 1 and improve the measurement accuracy.

The tip base 2 is a cylinder, and of course it can be in other shapes such as a rectangle, and a spike is provided under the tip base 2 .

One end of the slide bar clamp 4 is fixed below the slide bar caliper 5 by a spring, the middle position of the slide bar clamp 4 is directly connected to the slide bar caliper 5 , and the other end of the slide bar clamp 4 is against the slide bar caliper 5 .

In the utility model, the slide bar caliper 5 is movably connected to the measuring main bar 1 through the first slide bar 3, and the binding ring 6 is movably connected to the measuring main bar 1 through the second slide bar 8, the first slide bar 3 and the second slide bar 8 all slide up and down along the main measuring rod 1.

One end of the restraining ring 6 is fixed on the second sliding rod 8 , and the other end of the restraining ring 6 can be snapped into the fixing band of the second sliding rod 8 .

One end of the restraint ring 6 is fixed to the second slide bar 8 , and the other end of the restraint ring 6 can be fixed to the second slide bar 8 by Velcro.

In actual operation, insert the spiked part into one side of the root of the plant to be measured, adjust the position of the measuring main rod 1 according to the horizontal bubbler 7 until it reaches a horizontal position, and the height of the plant can be known by measuring the reading of the main rod 1, before measuring The tight-growing plants of the same species can be bound into bundles with the restraint ring 6, so that when measuring the average height, the manual manual restraint operation can be reduced, and the measurement work can be completed by a single person; The slide bar caliper 5 grips the stalk and takes a reading of the stalk diameter. In the meantime, the drooping leaves at the top of the plant can be clamped by the slide bar clamp 4, so that the effect of lifting the plant leaves can be achieved while moving the first slide bar 3 up, simplifying the operation of manually lifting the plant leaves to align the scale readings when measuring the maximum height of the plants .

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. Retouching should also be regarded as the scope of protection of the present utility model.
