Grain packaging machine

The present invention is relevant with grain packaging machine, the concrete relevant manual grain packaging machine that is used for such as field machines such as combining thresing machines, and wrapping machine has discharge drum, and being used for has hand door to be used for the discharge drum switch cereal grain sack of packing into.

Traditional grain packaging machine of the above-mentioned type has discharge drum fixing on body, and one section of discharge drum is stretched in the grain sack that is placed on the discharge drum below, in case grain is blown to four winds.

When the grain sack of filling is moved under wrapping machine, bag must be tilted, during operation, grain has the tendency that spreads out from sack.Spread out for anti-, the operator must be very careful.Therefore bothersome during operating cost.

Therefore, main purpose of the present invention is to propose a kind of improved grain packaging machine, purseful can be moved and grain is unlikely spreads out rapidly.

For achieving the above object, have following in the grain packaging machine of the present invention: a discharge drum of cereal being put into grain sack; Hand door with the discharge drum switching; Can be with the discharge drum vertical shifting; A linkage raises discharge drum when closing gate.

By the premises of the present invention, in emissions operation during the manual-lock gate, the closing gate discharge drum, simultaneously linkage make discharge drum the lower end upwards, leave with the grain sack mouth, grain sack can be moved rapidly easily like this, and do not needed its inclination.

This teamwork of discharge drum and gate also has and reduce the advantage that too much cereal is retained in tube.Therefore, when purseful was moved under discharge drum, the possibility that too much grain freely spreads out in the tube was very little.

And in a desirable embodiment of the present invention, linkage has one to delay mechanism, make discharge drum with respect to manually close lock the operation action delay.

In the running of this structure, during with the lock manual-lock, gate is closed discharge drum in emissions operation.Then linkage delay mechanism, the vertical motion that makes discharge drum is promptly carried out after discharge drum rises a predetermined distance with respect to closing lock running time-delay.

When being provided with this time delay device, the vertical motion of discharge drum can be carried out after to a certain degree at closing gate, reduces grain and discharges.Therefore, this arrangement can also effectively reduce the too much retention amount of an interior cereal.

As mentioned above, can carry out grain sack easily and rapidly with grain packaging machine of the present invention and move running, grain is spread out outside the bag, and machine can effectively prevent from too much to stay cereal in the tube and freely sheds and counteract.Therefore, this grain packaging machine save time and manpower aspect, the efficient of package handling is increased.

Now, be described in detail with reference to accompanying drawing to the desirable embodiment of grain packaging machine of the present invention.

Fig. 4 is the whole side-looking of the first scheme grain packaging machine, and wrapping machine is installed on the side such as field machine main bodys 7 such as combining thresing machines.As shown, machine has a hopper 1 to be placed on the predetermined upper position, makes charging usefulness, and a discharge drum 2 is placed on hopper 1 below.Discharge drum 2 has fixedly inner cylinder portion 2A, is placed on the bottom of hopper 1, and the 2B of outer movable tube portion is enclosed within fixedly upward activity of inner cylinder portion 2A.This movable tube 2B of portion slides up and down along the 2A of stationary magazine creel portion.In its down stroke end, the free lower end of the movable tube 2B of portion is stretched in the grain sack 3 that is placed on discharge drum 2 belows.And, a manual slide 5 that handle 10 is arranged is arranged, be fixed on this discharge drum 2.

Below discharge drum 2, a pair of level left and right sides bolster 8 is arranged, 8(only shows one of

axle

8,8 in the side-looking of Fig. 4, thereby axle overlaps each other), be supported on the avris of main body 7.These

bolsters

8,8 can support the vertical grain sacks of placing 3 in some discharge head fronts at discharge drum 2,

axle

8,8 be passed in each grain sack 3 about end go up the

jack

9 and 9 that forms.

In addition, as Fig. 1, shown in 2 and 3, there is a pair of

first support

14,14 to be fixed on the left and right sides of gate 5 and dividing

other support

14,14 to support the far-end of flexible pipes 11 and 11.The left and right sides of gate guide 12 supports gate to slide, 13,13 fixed installations of flexible pipe guide, and each guide 13 is curved downwards along the longitudinal axis of discharge drum 2.By

flexible pipe

11,11 is passed, support the middle part of flexible pipe from guide 13,13.In addition, below discharge drum 2, place a pair of about

second support

15 and 15, support the relative fortune end of flexible pipe 11,11.These elements are common to constitute a linkage A, and the movable tube 2B of portion of gate 5 and discharge drum 2 is connected.

When in running condition promoted closed shutter 5 with handle 10, this closing gate action was upwards drawn

flexible pipe

11,11 along the movable tube 2B of portion.When gate being moved to terminal point and closes fully, make the movable tube 2B of portion be in the end of its up stroke, at this moment the lower end of this part 2B leaves the oral area 4 of grain sack 3 upward.

Gate guide 12 provides friction to gate 5, does lax the support.Then, if handle 10 is pulled back, the movable tube 2B of portion begins to fall by deadweight.When moving gate 5 to close operator, gate 5 standard-sized sheets are put, and the movable tube 2B of the portion down stroke end under this state enters the internal upper part of grain sack 3 downwards by sack 4.

When the above-mentioned movable tube 2B of portion was in the up stroke end, there was the top clearance its lower end on grain sack 3.But the lower end of part 2B also can have fraction to stay in the bag 3, as long as there is not big influence when getting grain sack 3.

In addition, the movable tube 2B of portion also can utilize a downward thrust that plays the spring of this effect except that relying on deadweight, and activity tube subordinate is fallen.

The guide of the also available roller class of

flexible pipe guide

13,13 replaces.

Also the cylinder of available bellows replaces double-barrel structure discharge drum 2.

In such scheme, be flexible pipe controllable type device with the movable tube 2B of portion bonded assembly linkage A with gate 5.Otherwise also available rack pinion is realized the function of cable control types.Thisly easily will narrate hereinafter for connecting device.

Now referring to Fig. 5 and 6, the linkage of this programme has a pair of tooth bar to be fixed on the two lateral walls of gate 5 lower surfaces.And a pair of corresponding miniature gears 18 is fixed on the guide 12.And the side of these miniature gearss 18 is connected running by the first arm 20 and second arm 22 with the movable tube 2B of portion.

Say that more specifically each miniature gears 18 is fixed on the guide 12, rotate with respect to guide 12 around axle 17.18 1 sides of the first arm 20 far-ends and miniature gears are connected, around second 19 rotation.Another far-end of the first arm 20 is connected with the far-end of second arm 22, and

arm

20 and 22 can rotate relative to each other around third axle 21.In addition, the end in addition of second arm 22 is fixed on the movable tube 2B of portion, rotates with respect to the movable tube 2B of portion around the 4th 23.

In running condition, when driving handle 10 closed shutters 5, with tooth bar ingear miniature gears 18 rotation of gate 5, thereby second 19 of each miniature gears 18 moves up along figures.Like this, the first arm 20 is by on second 19 side that is fixed on miniature gears 18, and second arm 22 is connected with the first arm 20, and the therefore movable tube 2B of portion also moves up.

In said structure, suitably set the diameter of miniature gears 18, and/or the position of axle, just gate 5 may be connected with the movable tube 2B of portion, make the up stroke end of activity tube portion consistent with the gate full closing state.

In another embodiment of the present invention, linkage A has one to delay the B of mechanism, delays the lifting action of the movable tube 2B of portion with respect to the running of gate 5 manual-locks.

Now referring to Fig. 7 to 10, on gate 5 and the relative distal face fixing end face of handle 10, a hard-wired flexible pipe fabricated section 114 is arranged, have among crotch-shaped such as Figure 10 and overlook finding.This fabricated section 114 has hook portion 111A in both lateral sides, and 111A forms slotted

eye

114B, 114B, interpolation pin 117 on the side surface.And, annular metalwork 118,118 lax being placed on by long slot bore 114B are arranged, on the free end of the flexible pipe that 114B is overhanging, pin retainer 119,119 is fixed on the metal piece 118,118.Metal piece 118,118, hose

free end

11,11 captive joints.

On the other hand, identical with first scheme,

flexible pipe guide

13,13 is fixing with guide 12, slides in guiding gate 5 front and back, and the far-end of

guide

13,13 is along the axis bending of discharge drum 2.The sleeve 121,121 that the available screw of cover is regulated on

guide

13,13 horizontal ends.Therefore, the pars intermedia of

flexible pipe

11,11 stretches out from metal piece 118,118, passes sleeve 121,121 and

flexible pipe guide

13,13, and the opposite end of

flexible pipe

11,11 is installed on the

support

15,15 that is fixed on the activity tube portion 2B lower end.

In running condition, as shown in Figure 7, when handle 10 was promoted closed shutter 5, gate was closed gradually.But in this programme, in the elementary step of closing gate running, at long slot bore 114B, before the side wall of the 114B contact pin 117,117, the movable tube 2B of portion keeps static.Then, after the contact, as shown in Figure 8,

flexible pipe

11,11 upwards drawn, the movable tube 2B of portion is moved up by closing at 5 o'clock.Then, as shown in Figure 9, when gate was closed fully, the movable tube 2B of portion reached the extreme higher position, i.e. up stroke extreme position, and grain sack mouth 4 is upwards left in the lower end of the 2B of tube portion.

The movable tube 2B of portion is seized on both sides by the arms by flexible pipe 12 mat frictions.So as pulling handle 10 open gates 5, gate begins to open, the movable tube 2B of portion begins mat and conducts oneself with dignity.Though metal piece 118 during against sleeve 121 the whereabouts activity of the movable tube 2B of portion stop, the breakdown action of gate 5 still continues, until pin 117,117 and long slot bore 114B, the respective side end wall of 114B contacts.When the movable tube 2B of portion was in the down stroke extreme position, lower end and sack 4 were gapped.

As mentioned above, sleeve 112 is installed with flexible pipe guide 13 usefulness governing screw, but the mesh volume of free adjustment screw.Then, because element 118 contacts with sleeve 121, when metal piece 118 can not be further when guiding element 12 moves, the activity tube 2B of portion reaches extreme lower position.Therefore, by above-mentioned governing screw mesh volume, when regulating the position of these sleeves 121,121, just may the free adjustment extreme lower position, i.e. the down stroke end of the movable tube 2B of portion, thus the cereal amount of grain sack 3 is put in adjusting.

In this programme, can also make the movable tube 2B of portion have sub-fraction to stay in the bag 3, need only not quite the influence of getting grain sack 3.And the down maneuver of the movable tube 2B of the portion also downward thrust of spring of available used as said purpose is carried out.

Flexible pipe guide

13,13 can replace with the cable deflector roll.And also available bellows type tube replaces double sleeve type discharge drum 2.

Specify some modification measure below.

As shown in figure 11, can imagine, form two bolt hole 114C on each upper wall portions of 114B at long slot bore 114B, 114C, and on its each lower wall portion, form two screw hole 114D, 114D.So when by selecting that bolt 122,122 is inserted a pair of left and right sides Kong Zhongshi, pin 117 contacts with bolt 122 earlier with before the side wall of long slot bore 114B contact, thereby the starting of the acceleration activity tube 2B of portion vertical motion timing.Be exactly to pass through suitably selected screw 114D or the like, the just synergistic starting timing of possibility free adjustment gate 5 and the movable tube 2B of portion, i.e. the starting of the movable tube 2B of portion vertical motion is regularly.

As shown in figure 12, may imagine lengthening slotted eye 114B, thereby form the opening of the more close slotted eye 114B of gate 5.Therefore, just may behind the movable tube 2B of portion decline preset distance, keep gate 5 open.
