Integrated test soil moisture-content determination and pot handling device

Abstract

The invention discloses an integrated test soil moisture-content determination and pot handling device which is mainly composed of a longitudinal support beam, a grip, a digital display terminal, a mass inductor, and two symmetrically arranged transverse support arms, two symmetrically arranged suspension loops and two symmetrically arranged orientation wheels. One ends of the two transverse support arms are connected with the bottom of the longitudinal support beam, and the directional wheels are installed at the connection positions of the longitudinal support beam and the transverse supportarms; the other ends of the two transverse support arms are movably connected to the suspension loops, and the mass inductor is fixed on the suspension loops. The top portion of the longitudinal support beam is provided with the grip and the digital display terminal, the mass inductor is connected with the digital display terminal by a signal line, and the lower part of the longitudinal support beam is connected to a support rod in a hinge mode. According to the use of the integrated test soil moisture-content determination and pot handling device, test pots can be carried quickly, conveniently and efficiently; the quick weighing work for irrigation treatment pots is simultaneously completed; and the work efficiency is improved and the labor intensity is reduced, and also the test error is reduced and the test accuracy rate is improved.

Description

technical field [0001] The invention relates to a transport tool, in particular to an integrated test soil moisture content measurement and pot transport device used for studying the law of water demand for crop irrigation under pot test conditions. Background technique [0002] Soil moisture content generally refers to the absolute moisture content of the soil, that is, how many grams of water is contained in 100g of soil dried to constant weight, also known as soil moisture content. Measuring soil moisture content can grasp the law of crop water demand and save water resources. It has always been the focus of agricultural irrigation research and has important guiding significance for the promotion and application of agricultural scientific irrigation. [0003] Under actual potted conditions, the weighing method is generally used in the research on the law of water demand of crops, which is simple, quick, economical and practical, with high peer recognition of relevant test...

Problems solved by technology

[0008] 1. Many test personnel are required and the test period is long: According to the test requirements, generally 3-5 test personnel are required to complete the relevant test work, and the physical strength and endurance requirements of the test personnel are relatively high; and the corresponding requirements are difficult to meet in practice , which limits the development of related experiments

At the same time, the test steps are mainly broken down into six main processes: handling, weighing, recording, calculation, irrigation, and re-weighing. Each step consumes more time. In multi-processing and multi-level tests, it takes more time. Due to the time-consuming work of weighing pots and pots and watering, the time for carrying out other experiments is compressed, which is not conducive to the analysis of other experiments in crop irrigation experiments, and affects the breadth and depth of experiments.

[0009] 2. Low efficiency: During the potted crop irrigation test, it is necessary to replenish water for each pot, because of the difference in the quality of each pot and the quality of the internal soil, and the variability of crop growth and development. The difference between the pots will be more obvious, and the workload of watering each pot to reach the preset soil moisture content will be greater, resulting in high labor intensity and low work efficiency.
