Description
Technical field
The utility model relates to grain processing equipment field, particularly a kind of valving of thresher tunnel inlet joint.
Background technique
Rice is in course of working, often need to be ventilated in thresher by wind conduit, but the wind-force needed due to the processing of different rice is likely different, at this moment just need to provide a kind of valving to control the size of wind-force, first a valving is especially installed in the joint of thresher tunnel inlet and certain control is carried out to wind out from blower device limits.Because the wind-force of tunnel inlet joint is larger, general valving, under so large wind-force effect, is difficult to the requirement meeting stability, and therefore needing provides a kind of structure simple in thresher tunnel inlet joint, the valving that stability is higher, could meet actual needs.
Summary of the invention
The purpose of this utility model is the valving overcoming the deficiencies in the prior art and provide a kind of thresher tunnel inlet joint, and it has simple, safe, the stable advantage of structure.
The technical solution of the utility model is: a kind of valving of thresher tunnel inlet joint, comprise dial, operating stem, screw, valve block, inlet pipe, wind channel tube, wind channel tube is positioned at the top of inlet pipe, wind conduit and inlet pipe are bolted, and the bottom of wind channel tube is provided with circular opening; Dial is provided with one and ranked first tapped hole, and dial is positioned at the wind conduit above wind channel tube and inlet pipe joint, and dial and wind channel tube adopt rivet interlacement; Operating stem is L-shaped, and the horizontal component end of operating stem passes from the supravasal hole of wind, and welds together with valve block, and the vertical portion of operating stem is provided with the second tapped hole; Screw can be screwed in the first tapped hole and the second tapped hole simultaneously; Valve block is vertical with the vertical portion of operating stem.
The further technological scheme of the utility model is: described dial is arc structure, dial is provided with arc-shaped convex block, central angle corresponding to protruding block is 90 °, described first tapped hole is evenly distributed on protruding block, the quantity of the first tapped hole is 3 ~ 9, and dial is that starting point is numbered the first tapped hole from the first tapped hole of high order end.
The utility model further technological scheme is: the diameter of described screw head is greater than the diameter of the second tapped hole but is less than the Mean length of human body palm.
The utility model further technological scheme is: the surface of described operating stem horizontal component is smooth structure.
Further, when described screw inserts leftmost first tapped hole, the cavity in wind channel tube just in time covers by valve block completely.
The utility model compared with prior art has following features: valving that the utility model provides adopts screw and the operating stem, combined with the dial of the first tapped hole with the second tapped hole, can reach and the convenient openings of sizes regulating valve block, the positional stability of valve block can improve again, thus can control efficiency be improved.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that in the utility model, operating stem is connected with valve block.
Embodiment
As shown in drawings: a kind of valving of thresher tunnel inlet joint, comprise dial 5, operating stem 7, screw 6, valve block 3, inlet pipe 1, wind channel tube 8, wind channel tube 8 is positioned at the top of inlet pipe 1, wind conduit 8 is connected by bolt 2 with inlet pipe 1, and the bottom of wind channel tube 8 is provided with circular opening; Dial 5 is provided with one and ranked first tapped hole 5-2, and dial is positioned at the wind conduit 8 above wind channel tube 8 and inlet pipe 1 joint, and dial 5 and wind channel tube 8 adopt rivet 5 to be connected; Operating stem 7 is L-shaped, and the horizontal component end of operating stem 7 passes from the hole wind conduit 8, and welds together with valve block 3, and the vertical portion of operating stem 7 is provided with the second tapped hole; Screw 6 can be screwed in the first tapped hole 5-2 and the second tapped hole simultaneously; Valve block 3 is vertical with the vertical portion of operating stem 4.
Dial 6 is in arc structure, dial 5 is provided with arc-shaped convex block 5-1, central angle corresponding to protruding block 5-1 is 90 °, first tapped hole 5-2 is evenly distributed on protruding block 5-1, the degree of depth of the first tapped hole 5-2 can be increased like this, increase the area of contact of screw 6 and the first tapped hole 5-2, and then increase the stationarity of screw 6; The quantity of the first tapped hole 5-2 is 9; Dial 5 is that starting point is numbered the first tapped hole 5-2 from the first tapped hole 5-2 of high order end, and it is 10 ° that such operating stem 7 corresponds to valve block 3 with the variable angle amplitude of wind conduit 8 bottom surface in the movement often between adjacent two numberings.
The diameter of screw 6 head is greater than the diameter of the second tapped hole but is less than the Mean length of human body palm, and convenient operation librarian use hand operates, and screw 6 head is petal-shaped structure, reduces hand skid by concave and convex surface.
The surface of operating stem 7 horizontal component is smooth structure, and convenient operation bar 7 rotates along the hole bottom wind channel tube 8.
When screw 6 inserts leftmost first tapped hole 5-2, the cavity in wind channel tube 8 just in time covers by valve block 3 completely, and now valving is closed condition.
Working principle of the present utility model and using method are: when needs throttle down device, hold screw 6 head screw 6 to be back-outed the first tapped hole 5-2 but the second tapped hole 5-1 that do not back-out, rotating operation bar 7, now valve block 3 also and then rotates, when making the first tapped hole 5-2 of the second tapped hole 5-1 and the leftmost side on same straight line, stop operating operating stem, screw 6 is screwed into the first tapped hole 5-2 herein, tighten screw 6, operating stem has just been fixed, the cavity of wind channel tube 8 all covers by valve block 3, and to reach valve be closed condition.When valve needs to open, hold screw 6 head screw 6 is back-outed from the first tapped hole 5-2 of the leftmost side, then turn right operating stem 7, valve disc 3 is needed to be tens degree with acute angle folded by wind channel tube 8, the just span of mobile several first tapped hole 5-2, and then screw 6 is screwed in the first corresponding tapped hole 5-2, then tighten.When screw 6 is fixed on rightmost first tapped hole 5-2, valve disc 3 is parallel with wind channel tube 8, and valve is full open position.Can obtain from the above mentioned, can reach by being fixed on by screw 6 in the first tapped hole 5-2 in different numbering the corner dimension controlled between valve disc 3 and wind pipeline 8, and then the object controlling wind-force can be reached.
