A multifunctional portable crop ruler

Abstract

The invention discloses a multifunctional portable crop scale which comprises an external main scale with a T-shaped cross section. The external main scale is internally provided with a T-shaped chute. The T-shaped chute is internally provided with an inner sub-scale with a T-shaped cross section. The inner sub-scale can slide along the T-shaped chute. A through whole which penetrates through the inner sub-scale in a left-and-right direction is arranged at the upper part of the inner sub-scale. The left end of the external main scale is provided with a U-shaped trough which is internally provided with a flexible scale. The flexible scale is connected with a first shaft on the external main scale through a scale spring. The free end of the flexible scale extends into the front end of a first square hole and penetrates through the through hole arranged on the inner sub-scale, and then the free end of the flexible scale is connected with a flexible scale fixing clamping plate. A cover plate and the inner sub-scale are made of transparent plastic. A first vertical plate of the external main scale is provided with a fixing scale. The scale can perform telescoping and furthermore has advantages of high convenience in carrying, multiple functions and convenient operation.

Description

technical field [0001] The invention relates to a crop scale, in particular to a multifunctional portable crop scale. Background technique [0002] In agricultural scientific research, plant height is a very important agronomic trait, and a ruler is a commonly used measurement tool. Because some crops have a higher plant height, for example, the plant height of local rice varieties can reach more than 150 cm, and the plant height of corn and other crops can reach more than 200 cm. Conventional agricultural rulers are generally wooden rulers with a length of 1.5M-2.0M. One is easy to break and damage; the other is that it is too long to carry. For example, the trunk of a car cannot be opened; there are restrictions on the length of items to be carried or mailed when taking a train, a car, or by mail (more than 130 cm cannot be carried on the train); and agricultural scientific research often requires multi-point experiments and field investigations. to the ruler.

AI Technical Summary

Problems solved by technology

However, the traditional ruler can only measure the height of the plant, so in addition to the ruler, it is necessary to carry a ruler for measuring the length and width of the leaves, a marker pen for recording, and a paper for recording. Plant sampling sickle etc.

Carry a lot of things, and it is inconvenient to operate
