Abstract

The utility model relates to a grain airing spreading and taking up machine, which is composed of a main machine and a sucking and picking device connected by a 'double pipe sealing joint'. The 'double pipe sealing joint' is that two pipes axially arranged in parallel are communicated, can be moved, and are sealed by sealing rubber strips to form a flat shape 'double pipe negative pressure passage'. The double pipe negative pressure passages has the advantages of sucking and picking resistance reduction, negative high pressure resistance, good anti-wear performance, long service life, and convenient maintenance. The lower part of a sucking nozzle of the sucking and picking device is provided with a blowing nozzle, a blocking guide rubber strip, a cavity front guide part, and a sealing and pressing rubber strip, and grains on an airing place can be completely sucked. The grain airing spreading and taking up machine of the utility model can spread the grains at a speed of 65 thousand kg per man hour at the rush harvesting airing place, and can realize the mechanized operation such as sucking and picking operation, bagging operation, warehouse entering operation, spreading operation, purifying operation, and dust removing operation.

Description

Grain airing spreading and taking up machine

The utility model is a kind of machinery of grain airing, and existing grain airing is mainly by manpower and armstrong's patent, and efficient is low, and particularly cloudy day rainy day airing more needs to spread out soon soon receive.Reliable movable joint connects and the efficient device that picks up grain of inhaling owing to do not connect with main frame, and airing machinery is difficult to make successfully so far.

Owing to inhale and to pick up grain and need that machine power is big, negative pressure is high, general pivotable parts adopts soft coupling method, inhaled distortion easily, and picking up friction impact in the process in a large amount of grains suctions, soft draw bail is worn very soon, again since during airing grain pave thicker and the uneven existing various suctions in place are picked up device and are difficult to grain is exhausted.

The utility model picks up in suction and adopts two-tube sealing movable joint [15] to connect between device and the main frame [16], cooperate to inhale and pick up the guide wheel [10] of device front end both sides, this movable joint rotates in advancing, and keeps equidistant with ground during the suction nozzle [6] that can make suction pick up device [8] front end is advanced along ground under guide wheel [10] supports.

" structure of two-tube sealing movable joint [15] is: two tubular axis are to parallel; wherein a tube portion surface enters (see figure 2) among the breach of another pipe; form two pipe parallel alleys to passing through mutually; a pipe links with main frame [16]; another pipe is connected on to inhale and picks up device [8] and go up (seeing Fig. 1 and 2); transfer centre-to-centre spacing mechanisms [1] to be connected into hinges by two pipes on the central shafts [2] on the two pipe both sides end faces, it is movable that two-phase is passed through contact-making surface, the maximal clearance should be less than 1 millimeter, and such two pipes relatively rotate the formation movable joint along both sides central shaft [2].The contact-making surface outer surface that passes through mutually at two pipes is adorned " sealing joint strip [3] ", and the long limit of one is fixed on the tube wall face, and another long limit is adjacent to (see figure 2) with another tube-surface that passes through mutually and forms the sealing (seeing Fig. 1 and 2) that two pipes are passed through face mutually.Pass through mutually in the part at two pipes, have to inhale and pick up " two-tube negative pressure channel [13] " that device [8] communicates with the defeated way to move grains [11] of main frame [18], and in passing through mutually, leave in the lower channel on the pipe enough to satisfy and pick up " passing through tube wall face [12] mutually " that device rotates for inhaling, like this when inhaling when picking up grain under the effect in negative pressure, make the space between " sealing joint strip [3] " and two tube walls produce negative pressure by the two-tube gap of passing through mutually, " sealing joint strip [3] " are out of shape under the negative-pressure sucking effect are adjacent to two-tube wall more, the big more adhesive tape sealing of negative pressure is tight more.Because " sealing joint strip [3] " another side is unfixing, realized " sealing in the two-tube rotation " i.e. " two-tube sealing movable joint [15] ", movable " the two-tube sealing movable joint [15] " of " device is picked up in suction " and main frame cooperates down like this, in the support of its front part sides guide wheel [10] is advanced, realize that " front end suction nozzle [6] " moves forward with the equidistant of ground, for necessary condition has been prepared in the work of " device [8] is picked up in suction ".

Spread out in the advancing of receiving in airing, the suction nozzle [6] of this machine " device [8] is picked up in suction " is equidistant travelling forward in the grain inspiration machine apart from ground, realize packing transhipment work, but because threshing ground injustice or pitting and unclean near " dead band " grain suction on ground, must be at " suction nozzle [6] " back lower place dress " blowing mouth [4] ", this part grain is blown afloat, " suction nozzle [6] " could be with in the dead band China Oil and Food Import and Export Corporation food inspiration machine, dress on " blowing mouth [4] " preceding mouth wall " barrier guiding adhesive tape [5] " is adjusted and is made wind go up " dead band " earthward, the short circuit of avoiding drying is directly entered " suction nozzle [6] " and is run away in vain, because adhesive tape is soft and flexible, in shining the place, streaks projection and can resile." blowing mouth [4] " must be contained in " suction nozzle [6] " back lower place, and horizontal sextant angle is between 40 degree-70 degree, and it is relevant with blowing amount size apart from ground level with " blowing mouth [4] " that " the barrier guiding adhesive tape [5] " of its place ahead dress is lower than " suction nozzle [6] ".Suction air volume is big, and " barrier guiding adhesive tape [5] " is adjustable big apart from ground, otherwise turns down.Run wind in order to prevent " suction nozzle [6] " preceding grain from paving too uneven, the grain that paves on the threshing ground is pressed into uniform thickness, in the pre-installed semicircle of suction nozzle " cavity leading [9] " under shed, Open Side Down for it, on its forward position, install " envelope moulding bar [7] " additional, the grain that this " wind sealing bar [7] " will pave on the threshing ground flattens, and flexible resiling, and plays " suction nozzle [6] " anterior sealing function.For making " envelope moulding bar [7] " have bigger bullet to become the space, the width of " cavity leading [9] " " under shed [14] " should be greater than the width of " envelope moulding bar [7] ", " envelope moulding bar [7] " is lower than " suction nozzle [6] ", and itself and place height are pressed the grain paving thickness and decided.Obviously blowing mouth [4] and suction nozzle [6] and guide wheel [10] are all made adjustable mechanism apart from distance between the ground, the convenient adjustment.

The utility model grain airing spreading and taking up machine adopts " two-tube sealing movable joint [15] ", make grain stream through " two-tube negative pressure channel [13] " of flat wherein and suction nozzle [6] width near consistent, reduced to inhale and picked up resistance, be that hard tube connects trochanter, anti-negative high voltage, the metal passage wearability is good, long service life, safeguard, to change " sealing joint strip " cost low, easy to maintenance.Pick up in the device in suction, owing to adopt " air draught mouth [4] " and " barrier guiding adhesive tape [5] ", " cavity leading [9] " and " blast adhesive tape [7] " can all exhaust grain on the place.Owing to solve and significantly improved the high efficiency of " device is picked up in suction ", durable better function.The utility model " grain airing spreading and taking up machine " is received 130,000 jin in grain per man-hour getting the harvest in quickly the grain that paves on the threshing ground, and to grain pack, put in storage, pave, purification, dedusting realize mechanization.
