Soil pH detecting device

Abstract

The invention relates to a soil pH detecting device. The soil pH detecting device comprises a movable top plate and a detecting unit, wherein the movable top plate is provided with an observing hole,the bottom of the external end of the movable top plate is provided with a sliding groove, and the detecting unit is mounted at the bottom of the movable top plate; the detecting unit comprises a pushair cylinder, a detecting support plate, a clamping rack, a clamping push rod, a pressing mechanism and a wiping mechanism; the wiping mechanism comprises a wiping sliding bar, a wiping moving block,a wiping support plate, a wiping extending rod, a wiping spring, a wiping pressure block, a cleaning cloth, a winding roller, a recovering roller and a recovering motor. The soil pH detecting devicecan solve the problem that, during existing soil pH detection, an existing soil detector cannot limit the inserted depth and requires manual compaction of soil around the soil detector, manual cleaning of soil adhered to the lower end of the soil detector and the like; meanwhile, the soil pH detecting device can achieve functions of soil pH detection and post-detection wiping and cleaning.

Description

technical field [0001] The invention relates to the field of agricultural instruments and meters, in particular to soil pH detection equipment. Background technique [0002] Soil acidity or alkalinity are important factors that limit plant growth and quality. Most plants are not tolerant to acidic or alkaline soils; therefore, it is very important to know the pH and humidity of the soil. The soil acidity meter is an instrument used to detect soil pH. The upper end of the soil acidity meter is a cylindrical structure, and the bottom of the soil acidity meter is a pin structure. Insert the pin at the bottom of the soil acidity meter into the soil to be tested. The soil acidity meter The top dial shows the pH of the soil. [0003] When the soil detector performs pH detection, the lower end of the detector needs to be inserted into the soil, and the soil around the detector needs to be compacted, and the detector needs to be cleaned after the soil detection is completed to prev...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above problems, the present invention provides a soil pH detection device, which can solve the problem that the insertion depth of the detector cannot be limited when the soil is detected in the existing soil pH detection, and the soil around the detector needs to be manually pressed. The soil attached to the lower end of the detector needs to be removed manually. It can realize the pH detection of the land and the function of wiping and cleaning the detector after detection. It has the function of limiting the insertion depth of the detector during land detection, and automatically The soil around the detector is compacted, and the soil adhered to the lower end of the detector is mechanized to be removed, etc.
