Determinator capable of determining hardness of agricultural seedling pot body block on site

Abstract

The invention discloses a determinator capable of determining the hardness of an agricultural seedling pot body block on site. The device structurally comprises a first side plate, a bottom plate, a pressure scale, a tray, a pressure disc, a bearing, a screw, a top plate and a second side plate, the first side plate is parallel to the second side plate; two sides of the bottom plate are verticallyconnected with the middles of the first side plate and the second side plate respectively; two sides of the top plate are respectively connected with the tops of the first side plate and the second side plate; pressure scale is arranged on the bottom plate, the top of the pressure scale is connected with a tray; pressure plate arranged above tray, the top of the pressure plate is movably connected with the bottom of the screw; the screw is in threaded connection with a threaded hole formed in the middle of the bottom plate; the pressure plate comprises a first pressure rod, a plate body, moving structures, a second pressure rod and a third pressure rod, and the three moving structures are arranged at the bottom of the plate body. The pressure plate has the beneficial effects that the pressure rods can be moved to the middle of the plate body when needed through the arranged moving structures, force application of the pressure plate is accurate, and deviation is prevented.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a measuring device capable of measuring the hardness of agricultural seedling pots on the spot. Background technique [0002] With the requirements of intensification, mechanization and green energy-saving development, the current rice cultivation methods have new developments. In the conventional paddy field transplanting, the hardness of the pot body of rice seedlings has a great impact on the handling, transportation and machinery of pot seedlings. Claw seedling separation and so on are key application indicators; especially for the newly developed method of transplanting seedlings in dry fields, the hardness of pot seedlings is a key index; Spreading etc. is very important. [0003] The application number of the prior art is 201910038154.2, a measuring device and its measuring method that can measure the hardness of the agricultural seedling pot block on the spot, and it is used t...

AI Technical Summary

Problems solved by technology

The measurement method includes preparing a measurement plane; placing a pressure device on the measurement plane, placing a pressure display under the horizontal frame of the pressure device, placing a measurement board on the pressure display, and then placing the agricultural seedling pot body block on the measurement board; Insert the pressure column into the block of the agricultural seedling pot to a certain depth; rotate the pressure adjustment screw to realize the gradual downward movement of the pressure device as a whole until the block of the agricultural seedling pot is broken; read the maximum pressure value on the pressure display, but the pressure column of the prior art There are different diameters, which are distributed in different positions of the pressure plate. If they are not located in the middle of the pressure plate when pressing down, the force of pressing down will be biased
