A device for testing the mechanical properties of plug-in seedlings and bowls

Abstract

The invention relates to a potting seedling pot-clamping removal mechanical property testing device. The potting seedling pot-clamping removal mechanical property testing device is characterized in that a pressure sensor A is arranged between an oscillating bar A and a clamping needle A, a pressure sensor B is arranged between an oscillating bar B and a clamping needle B, a clamping force mechanism capable of testing the mechanical properties of the clamping needle A and the clamping needle B acting on a seedling pot can be formed under the pull effect of a supporting bar A, a supporting bar B and a drawing bar, a drawing pressure sensor which can slide up and down is installed on a crossbeam of the clamping force mechanism is used for forming a lifting force mechanism capable of testing the mechanical properties of the clamping needle A and the clamping needle B which are inserted into the seedling pot and lift the seedling pot, and a testing system for acquiring the pot clamping removal mechanical properties by virtue of a computer system can be formed by utilizing a mature mechanical sensor technology. By adopting the device, the mechanical property test on the seedling pots with different structural characteristics which can be independently inserted, clamped and lifted by the clamping needles can be realized, an important significance on comprehensive researching of the pot clamping removal technology can be achieved, and the potting seedling pot-clamping removal mechanical property testing device can be applied to the research of an automatic potting seedling transplanting machine.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a device for testing the mechanical properties of vegetables, flowers and other plug-in seedlings for clamping and detaching. Background technique [0002] In recent years, the research on the mechanized transplanting technology of plug seedlings in my country has attracted much attention. With the shortage of skilled agricultural labor and the increasing labor costs, it is urgent to break through the technology of automatic and efficient transplanting of plug seedlings. Foreign automatic transplanting machines are complex in structure and high in cost, and are not compatible with my country's seedling raising technology and other transplanting auxiliary operations, which reduces the success rate and efficiency of transplanting. Therefore, the way to introduce foreign automatic transplanting technology is not feasible, and we must rely on independent research and development. [0003]...

AI Technical Summary

Problems solved by technology

The force measuring platform of the present invention can carry out the research on the clamping force of the seedling pot, which solves the problem of clamping research, but it cannot study the mechanical properties extracted from the hole after the seedling pot is clamped, nor can it test and analyze the force during the insertion process of the clamping needle. Therefore, the test clamping table cannot comprehensively study the mechanical properties of the automatic clamping of the needle into the seedling pot, clamping the seedling pot, and extracting the seedling pot, and the test clamping table needs the help of a universal testing machine as a basic platform. Make pot characterization testing dependent on existing instruments
