Description

A kind of grain moisture content testing sensor

Technical field

The utility model relates to the grain testing apparatus, is a kind of grain moisture content testing sensor.

Background technology

Because the applicant specializes in the production of grain tester, thus to grain tester device design more multiple structure, wherein obtained multinomial patent right.Because the test of grain moisture content is the indispensable step that grain stores and processes, and there are certain difference in powdery and the test of granular grain, particularly in use find, there are deficiencies such as complicated operating process in some proving installation, so all there is deficiency in the graininess grain moisture content testing sensor of Xiao Shouing in the market.

Summary of the invention

The purpose of this utility model provides a kind of grain moisture content testing sensor, and it is mainly used in particle tested shape grain, it is had test advantages such as accurate, easy and simple to handle.

The utility model for achieving the above object, be achieved through the following technical solutions: a kind of grain moisture content testing sensor, comprise shell, gland is installed on the shell, shiny surface contacts between shell and the gland, on the bottom surface of shell base is set, and first electrode contact is installed on the base, second electrode contact and third electrode contact, first electrode contact is connected with first spring leaf, the third electrode contact is connected with the 3rd spring leaf, installs in the shell and surveys tube, surveys fitting insulating panels in the tube, installing electrodes plate below the insulcrete, mounting center electrode on the battery lead plate, installing electrodes on the insulcrete is surveyed the tube bottom mounting spring, shell one side is offered through hole, and connecting line is installed in the through hole.The uncovered end face of shell is the plane, and the uncovered end face of gland is the plane, and the uncovered end face of shell contacts with the uncovered end face of gland.The shell open-mouth is provided with outside boss, and the inwall of shell is higher than the outer wall of shell, and the external diameter of shell is greater than the inwall external diameter of shell, and the uncovered end face of gland contacts with the boss place.Offer first through hole, second through hole and third through-hole on the base of installing in the shell, first through hole is connected with base one side.Base adopts bolt to be connected with the shell bottom surface, and bolt penetrates outer casing bottom.

Advantage of the present utility model is: it is particle tested shape grain moisture content accurately, can accurately transmit signal, and is easy and simple to handle, quick, thereby shortens the test duration, has increased substantially work efficiency etc.

Description of drawings

Accompanying drawing 1 is the utility model structural representation; Accompanying drawing 2 is A-A sectional structure synoptic diagram in the accompanying drawing 1.

Embodiment

2 is shells among the figure, and structure described in the utility model is: gland 1 is installed on the shell 2, and shiny surface contact between shell 2 and the gland 1, and when being convenient to test, operating personnel directly push, and increase pressing force according to data presentation, make test operation directly, succinctly, quick.Base 23 is set on the bottom surface of shell 2 described in the utility model, first electrode contact 12, second electrode contact 11 and third electrode contact 10 are installed on the base 23, first electrode contact 12 is connected with first spring leaf 14, third electrode contact 10 is connected with the 3rd spring leaf 13, install in the shell 2 and survey tube 3, survey fitting insulating panels 5 in the tube 3, installing electrodes plate 8 below the insulcrete 5, mounting center electrode 7 on the battery lead plate 8, installing electrodes 6 on the insulcrete 5, survey tube 3 bottom mounting spring 9, shell 2 one sides are offered through hole 24, and connecting line 25 is installed in the through hole 24.The utility model shell 2 is connected with the shiny surface contact of gland 1 can multi-scheme, and for example: shell 2 uncovered end faces are planes, and gland 1 uncovered end face is the plane, and shell 2 uncovered end faces contact with gland 1 uncovered end face.Further scheme can also be: shell 2 open-mouths are provided with outside boss, the inwall of shell 2 is higher than the outer wall of shell 2, the external diameter of shell 2 is greater than the inwall external diameter of shell 2, and the thickness of shell 2 inwalls and the thickness of outer wall do not limit size, and gland 1 uncovered end face contacts with the boss place.All schemes all adopt gland directly to be placed on the mode that manpower is pushed on the shell 2 downwards, have solved complicated operation in the known technology, the deficiency that the running time is long.The utility model is enhanced productivity in order to further facilitate the various parts of assembling, offers first through hole 22, second through hole 21 and third through-hole 19, the first through holes 22 on the base of installing 23 and be connected with base 23 1 sides in shell 2.Base 23 described in the utility model can be set to one with shell 2, and the split design is convenient to assemble each parts, also has advantages such as being convenient to maintenance simultaneously.Base 23 adopts bolt 20 to be connected with shell 2 bottom surfaces, and bolt 20 penetrates shell 2 bottoms.Among the figure, the 4th, battery lead plate, the 15th, pilot hole under the spring, the 16th, pilot hole on the spring, the 17th, insulation sleeve, the 26th, ply-yarn drill head, the 27th, electrode.
