Embodiment
Embodiment one
As shown in Figure 1, walking chassis 11 installed in front cross conveyor 14, its concrete structure describes below in conjunction with Fig. 9 the industrial hemp standing position conveying grain header of the present embodiment.One group of grain lifter 13 that the support installing at cross conveyor 14 top extends towards front lower place, its concrete structure is below in conjunction with Fig. 7, describe with 8.Cutter sweep 12 is installed in the bottom of cross conveyor 14, and its concrete structure describes below in conjunction with Figure 10.The output of cross conveyor 14 is connected with the input of the longitudinal conveying device 15 be placed in above chassis 11 of walking, the output of this longitudinal conveying device 15 be positioned at be placed in walking chassis 11 on rear side of collection stalk case 16 above.
The concrete structure of longitudinal conveying device 15 as shown in Figures 2 to 6, comprises the conveying mechanism z-11 be supported on underframe z-14 and the clamping device z-12 being positioned at conveying mechanism side.The pin z-25-1 at the adjustable shelf z-25 two ends of top braces conveying mechanism z-11 is inserted in the vertical column z-14-1 at underframe z-14 two ends, the middle part of the top braces adjustable shelf z-25 of oil cylinder lifting z-13, therefore can regulate and control the height of conveying mechanism easily as required by elevating mechanism.
Conveying mechanism z-11 as shown in Figure 3, is made up of the chain z-22 be looped around on both ends horizontal transportation sprocket z-21.Chain z-22 is intervally distributed with moving tooth z-22-1 outwardly, around inner side contiguous with the chain guide z-24 being connected in adjustable shelf z-25, therefore can avoid flexure when clamping, strong forced conveyance effect is played to large anesthesia stem.One of transportation sprocket z-21 is by fluid motor-driven.
As shown in Figure 4, pass through the fixing mounting bar z-32 of two shape installing rack z-31 containing with underframe z-14, this mounting bar z-32 is parallel to side chain to clamping device, and an axle bed z-45 vertical is with it fixed at interval.As shown in Figure 5, the plug-in mounting dynamic fulcrum z-33 coordinating formation moving sets with it in the endoporus of axle bed z-45 is propped up.Fulcrum z-33 has expanding back-up ring with an axle bed z-45's respectively away from holding, and the spring z-43 making fulcrum z-33 be tending towards close chain z-22 is housed between two expanding back-up rings.The overhanging end of every root fulcrum z-33 is between one jiao of the paired upper and lower grip block z-35 be mutually connected, and be inserted in the horizontal jack z-42-2 of the Connection Block z-42 with vertical hinge pin hole z-42-1 (see Fig. 6), simultaneously hinged by the adjacent corners of vertical hinge pin z-41 and this paired upper and lower grip block z-35 and the upper and lower grip block of Adjacent pairs through vertical hinge pin hole again, thus formation is by the hinged grip block chain of the paired upper and lower grip block z-35 of continuous print.The middle part of paired upper and lower grip block z-35 is connected by riveting pin z-44 riveted joint.
In order to make the concordant transition in upper and lower surface of grip block chain, the side of paired upper and lower grip block z-35 forms decline face z-35-1 and raised floor z-35-2 respectively, therefore can inject between adjacent paired upper and lower grip block z-35 during assembling, form the upper and lower surface of concordant transition.In addition, the card z-35-3 forming the gap that to match with adjacent upper grip block thickness is fixed in the inner side of decline face z-35-1, can retrain the upper and lower of the upper and lower grip block of Adjacent pairs 35 and float after therefore inserting adjacent upper grip block z-35 during assembling.
In order to the large anesthesia stem of the paired upper and lower grip block z-35 more reliable retention thickness inequality that makes each grip block chain element, the decline face z-35-1 of paired upper and lower grip block z-35 and raised floor z-35-2 installs hinge pin z-41 by long slot bore z-35-4.Grip block chain can be made like this to have larger horizontal float degree of freedom, even if because the large anesthesia stem density of conveying is larger, when same paired upper and lower grip block z-35 need clamp the large anesthesia stem of thickness inequality simultaneously, paired upper and lower grip block z-35 can by the micro-degree of freedom of inclining of self, automatically adjust the chucking power to the uneven large anesthesia stem of thickness, meet the demand of reliable retention.
In order to make large anesthesia stem easily input at the input of conveying mechanism z-11, the head joint of grip block chain guides grip block z-34 to form by arc.In order to guarantee that at output large anesthesia stem comes off, the output of conveying mechanism z-11 is equipped with antiwind dropping mechanism z-15, and this mechanism, by stopping that the antiwind cover z-61 that comes off of the V-shaped of backhaul pathways is formed, can force large anesthesia stem to be separated with conveying mechanism z-11.
The grain lifter 13 of the present embodiment as shown in Figure 7 and Figure 8, standing grain point rounded triangle grain lifter f-11 down is fixedly held up in the lower end of installation frame f-16, and the rear portion of grain lifter f-11 is equipped with low early and high after and is intervally distributed with L shape and turns the active belt f-22(of plate f-23 also known as movable joint belt).On the small belt pulley f-21 that active belt f-22 is looped around interval arrangement and big belt pulley f-24, its conveyor side (having conveying arrow side) is concordant with one side of grain lifter f-11, return to side to turn plate f-23 together with L shape and be all included in the another side of grain lifter f-11, thus constitute the Fu He mechanism that biased active belt and star-wheel combine.Tensioning apparatus f-12 is equipped with at small belt pulley f-21 place.Big belt pulley f-24 is coaxial with the star-wheel f-25 of circle spacing uniform moving tooth, and star-wheel f-25 is upper, and the spacing that the pitch of its moving tooth and L-type turn plate matches, and therefore constitutes two layers at this position and synchronously holds up standing grain structure for conveying, ensures that stem stalk holds up the stable smoothness of standing grain.The moving tooth conveyor side of star-wheel f-25 is circular arc, and moving tooth radical length and L shape are turned the length that plate f-23 stretches out active belt f-22 and matched.
In addition, the tangential extension clamped wire f-26 relative with chain-type conveyer f-15 is equipped with in the active belt f-22 output of grain lifter f-11.Contiguous star-wheel f-25 place, installation frame f-16 lower end is supported with the chain-type conveyer f-15 be connected with star-wheel f-25, and this chain-type conveyer f-15 has the pusher dog f-15-1 engaged with the moving tooth of star-wheel f-25.Therefore, under the drive of chain-type conveyer, star-wheel rotates, and then drives active belt to follow to move together.
The structure of cross conveyor 14 as shown in Figure 9, be made up of the upper, middle and lower three groups of chain-type conveyers extended about walking direction of advance, under first group of chain-type conveyer h-46 and second group of middle chain-type conveyer h-45 be fixed on lateral transfer fixed mount h-44, be installed on lateral transfer adjustable shelf h-42 at the upper the 3rd group of chain-type conveyer h-41, three groups of chain-type conveyers are connected by universal joint h-43, lateral transfer adjustable shelf h-42 and lateral transfer fixed mount h-44 forms the vertical moving sets regulating and fix, by the height of the adjustable 3rd group of chain conveyor h-41 of hydraulic jack, thus adapt to the harvesting conveying of differing heights hemp.
The structure of cutter sweep 12 as shown in Figure 10, be connected in chassis assembly 11 by ceding of Taiwan hanger bracket q-31, cutting-height adjustment is carried out by hydraulic jack, reciprocating double dynamical q-33 carries out transmission by drag link q-32, power is provided by hydraulic motor, due to the similar with prior art, therefore do not describe in detail.In the clamped wire of ceding of Taiwan leading portion two groups of differing heights and cross conveyor, lower two groups of chain-type conveyers carry out clamping and carry.
During harvesting, take the circumstances into consideration the height adjusting grain lifter and longitudinal conveying device, what make grain lifter is highly positioned at hemp stalk middle and lower part foremost, the corresponding hemp stalk middle and upper part of pressure retaining part of longitudinal conveying device.Walking chassis moves ahead in process, under grain lifter effect, hemp stalk enters cutter sweep cutting, hemp stalk after cut-out is under the effect of clamped wire and cross conveyor three groups of differing heights chain-type conveyers, conveying is clamped left by the right side of direction of advance, until forced clamping by longitudinal conveying device, be steadily delivered to collection stalk case, after the collection of collection stalk case is full, carries out dumping by hydraulic jack.
