Description
Technical Field
The invention relates to agricultural machinery, in particular to a harvester for harvesting corn ears and stems, and specifically relates to a header of a P-type differential ear-stem harvesting corn harvester.
Background
Corn as a crop forms a three-minute pattern with wheat and rice, and plays a role in the industrial and agricultural fields. As the corn straw which is the product in the same period with the corn seeds, the yield of the corn straw is far higher than that of the corn seeds, the sustainable ecological cycle development of agricultural economy in China is realized by recycling the corn straw, and the advanced degree of the corn harvester with both ears and stems is also an important influencing factor of the modern process of agriculture in China.
The existing corn harvesters with multiple ears and stems have the following outstanding problems in the actual production process, namely 1. For row harvest, the agricultural difference of the existing corn planting in China leads the opposite row machine type to be incapable of performing cross-region operation, the planting method is not standardized, so that the opposite row harvester type is seriously lost in the operation process, unnecessary loss is caused, the height of the remained stubble is uneven after harvesting, and the next stubble cultivation is affected; 2. the single-row single plants of part of the machine type are cut up, the cutting width is smaller, the working efficiency is low, and soft corn bracts and plant leaves cannot be compressed, so that the whole leaves cannot be cut up and remain, and the quality, management and use of grass are seriously affected; 3. most machine type cutting tables are divided into an upper layer structure and a lower layer structure, and the upper layer ear picking device is higher, so that the lowest ear picking height of corn plants is limited, and the adaptability of the whole machine to different corn varieties and regions is restricted; the lower layer collects the straws by a spiral auger, and the concentrated straws enter a chopping device in a disordered state, so that the length of the cut straws is uncontrollable and uneven, and the downstream production is affected; 4. the cutting knife on the harvester is generally a reciprocating cutting knife, the motion track of the reciprocating cutting knife is a transverse straight line, the moving track of the poking finger for clamping and conveying plants is a circumferential and longitudinal straight line, and the cutting and clamping conveying are asymmetric, so that the stalk harvesting and cutting rate and the stalk loss rate are improved; 5. the corn kernel is seriously lost in the harvesting process due to the extrusion-stripping type spike picking mode, the mechanical operation cannot be performed on fresh corn, meanwhile, the production power consumption of a corn harvester is improved, and the burden of farmers is increased.
Disclosure of Invention
The invention provides a P-type differential corn cob and stalk harvesting header for solving the problems.
The invention is realized by adopting the following technical scheme: the header of the P-type differential ear and stem harvesting corn harvester comprises a frame, wherein a plurality of harvesting units which are symmetrically arranged left and right and are mutually independent, an ear conveying device and a grass cutting device or a grass conveying device are arranged on the frame; each harvesting unit comprises a large grain divider, a small grain divider, an outer push rod, a grain pulling disc, an upper conveying disc, a lower conveying disc and a cutting disc which are sequentially arranged from top to bottom, wherein the diameter of the lower conveying disc is smaller than that of the upper conveying disc, grain pulling disc fingers, conveying disc pulling teeth and cutting disc cutters are respectively and uniformly distributed on the grain pulling disc, the rotating speed of the conveying disc is larger than that of the grain pulling disc, the large grain divider is positioned at one side of the grain pulling disc, the small grain divider is positioned in front of the grain pulling disc, the tail end of the small grain divider is provided with a front upper conveying guide rod and a front lower conveying guide rod, the large grain divider is provided with a side upper conveying guide rod and a side lower conveying guide rod, the conveying guide rods are arc-shaped rods, and a gap between the front upper conveying guide rod and the grain pulling disc, a gap between the side upper conveying guide rod and the outer push rod and a gap between the side lower conveying guide rod and the lower conveying disc form a plant conveying channel; each harvesting unit further comprises two parallel snapping rolls, each snapping roll is wound with a spiral rib and a pair of single-circumference spiral tool setting tools and is obliquely arranged at the front lower part and the rear higher part, an arc-shaped guard plate is arranged at the outer side of each snapping roll, spike blocking rods are arranged on the arc-shaped guard plate, holding rods are further arranged above the arc-shaped guard plate and are respectively connected with a side upper conveying guide rod and an outer pushing guide rod in a head-tail mode, gaps between the two holding rods and gaps between the two spike blocking rods are larger than the diameter of plants and smaller than Yu Guosui diameter, the gaps between the two spike blocking rods are coaxial with the gaps between the two snapping rolls after being deviated, the gaps between the two holding rods, the gaps between the two spike blocking rods and the snapping roll gaps jointly form a spike picking channel, and the two spike blocking rods are arranged at one higher part and one lower part; the ear cutting circular knife is fixed above the tail end of the ear blocking rod, an ear cutting gap is formed between the top surface of the tail end and the ear cutting circular knife, the ear pulling rod extending outwards is further connected to the middle of the grain holding rod, the tail end of the ear pulling rod extends to the lower side of the ear cutting circular knife, and the grain holding rod is turned into downward backward extension after rising to a certain height, and is ended in the gap between the two ear cutting circular knives. A grass pulling chain and a grass guiding groove which extend to the grass feeding roller or the grass conveying roller are arranged below the snapping roller; the rear lower part of the snapping roll is also provided with a snapping plate, a ear conveying device, a main lift conveyer interface and a grass cutting device or a grass conveying device, the grass cutting device comprises a grass feeding roll, a grass pressing roll and a grass cutting cutterhead, and the grass conveying device comprises a grass conveying roll.
When the harvester walks forwards, corn plants are righted by the crop divider, cut off by a cutting disc cutter rotating along the circumference and grabbed by a next crop poking disc, the corn plants are forced to be sent into a conveying channel formed by a front upper conveying guide rod and the crop poking disc along a front conveying guide rod, when the corn plants are conveyed to a narrow position of the conveying channel (as shown in figure 4), the upper conveying disc poking teeth penetrate into plant stalks, and as the rotating speed of the conveying disc is higher than that of the crop poking disc, namely the linear speed of the upper conveying disc poking teeth is higher than that of the crop poking disc poking fingers, the upper conveying disc poking teeth push the plants poked by the crop poking disc to the direction of the crop poking disc poking fingers adjacent to the downstream of the crop poking disc poking fingers, so that a space is reserved for the next plant to enter a gap between the two crop poking discs, and the next plant is orderly arranged with the previous plant, and a plurality of plants poked by the same crop poking disc are realized between the two crop poking disc poking fingers so as to enter the gap of a picking roll; before the plants are sent into the snapping roll gap, under the combined action of the side upper conveying guide rod, the side lower conveying guide rod and the outer push rod, the plants are forced to incline by taking the upper conveying disc poking teeth as supporting points so as to avoid the interference of rotating poking disc poking fingers on the plants; the lower stem of the inclined plant is penetrated by the poking teeth of the lower conveying disc under the compression of the side lower conveying guide rod; therefore, plants safely and reliably enter the snapping roll gap under the double action of the upper conveying disc and the lower conveying disc. When plants enter the gap entrance of the snapping roll, the plants are blocked by the snapping roll and separated from the rotating conveying disc poking teeth, and are pushed backwards by the helical ribs of the snapping roll, enter the gap of the snapping roll, and the corn plants entering the gap are pushed backwards and downwards by the opposite rotating snapping rolls.
The plants enter the gap of the snapping roll and simultaneously enter the gaps of the parallel straw holding rods and the parallel ear blocking rods, and the gaps of the straw holding rods and the gaps of the ear blocking rods are properly deviated to the same side of the gap of the snapping roll. The front ends of the two straw holding rods are respectively connected with the lateral upper conveying guide rod and the outer pushing rod, and the horn mouth extends backwards and upwards from wide to narrow and from low to high, so that plants with different heights are collected into the gap between the two straw holding rods. When the straw is lifted to a certain height, the straw is turned into downward and backward extension, so that the ears with any height can be blocked below the straw, and the bent and extended straw is used for separating the ears with different heights from the stalks along with the downward and backward pushing of the plants by the snapping rolls, so that the stalks are prevented from being cut off by the circular knife, and the impurity content of the ears is improved.
As shown in fig. 9, when a plant is pushed downwards until the cluster contacts with the cluster blocking rod, the cluster with larger diameter is blocked by the cluster blocking rod with smaller gap, as the proper amount of widened cluster picking roller gap reduces the downward drag force of the cluster picking roller to the plant, the proper amount of offset support rod and the proper amount of cluster blocking rod which is arranged at a height and a low position enable the plant to be moderately bent and deformed, the friction force of the support rod and the cluster blocking rod to the stem is enhanced, thus the weakened drag force is insufficient to overcome the friction force and the growth adhesion force of the cluster, the plant is not pushed downwards any more, the cluster cannot be picked off, at the moment, the cluster carrying plant is only pushed backwards in the cluster blocking rod direction by the backward push force of the cluster picking roller spiral rib, the cluster blocking rod extending from the support rod pulls the cluster from the upward slope to the horizontal direction until the cluster is drooping, the cluster connecting the cluster with the cluster blocking rod transversely enters the circular knife and the cluster blocking rod along the cluster blocking rod, and the rotating cluster cutting knife cuts off the cluster, and the cluster is separated; the separated and cut ears slide down along the ear guide plate onto the ear conveyor belt and are conveyed to the elevator to enter a peeling mechanism (or threshing mechanism) or a granary.
When the plants enter the gap of the snapping roll, a grass pulling chain below the snapping roll clamps the plant stalks below the snapping roll and pushes the plant stalks backwards along the grass guiding groove, so that the downward pulling force on the plants is not increased due to the external force such as the grass feeding roll or the grass conveying roll in the whole process of picking the ears, when the roots of the pushed stalks are about to enter the gap of the grass feeding roll or the grass conveying roll, the plant stalks are cut by a spiral tool setting (shown in fig. 11 and 12) arranged on the snapping roll, the cut upper stalks continuously move backwards downwards under the action of the snapping roll, and finally, the cut lower stalks and the stalks after the upper ears are conveyed to a grass cutting device or a grass conveying device by the grass pulling chain in the order of the roots and the parts behind the roots. The stalks entering the grass cutting device are compacted and cut up and then thrown to a transport vehicle or a field; the stalks entering the grass conveying device are completely delivered to a bundling mechanism or a piling field at the host machine position behind the cutting table.
The invention has the beneficial effects that:
1) The whole machine has simple structure and reliable operation due to the unsupported cutting, and the production and use cost is reduced;
2) The cooperation of the disc type cutting, the crop divider and the conveying device realizes the non-line harvesting of corn plants, so that the harvester can enter the field operation from any direction, the turning time is shortened, the working efficiency is improved, and the corn harvester can adapt to various planting agronomic and planting specifications, and the cross-region operation becomes reality;
3) The differential conveying mode of the conveying disc and the reel enables corn plants to be conveyed in a vertical single plant row mode, and provides reliable and necessary conditions for smoothly completing the ear picking process;
4) The cutting and clamping conveying synchronously run in the same track, so that the clamping conveying blind area is eliminated, and the rod breaking rate and the field loss rate are reduced;
5) The cutting-off type ear picking mode avoids the collision and impact of the ears in the ear picking process, reduces the loss rate of seeds, simultaneously realizes the mechanized operation of fresh corn, reduces the labor intensity of farmers and improves the utilization rate of the harvester;
6) The cutting-off type ear picking reduces the power consumption, is convenient to use hydraulic drive, provides conditions for the complete machine to realize intelligent control, and reduces the operation cost;
7) The stalks after picking the ears are collected along the axial direction of the stalks in the sequence of the root part and the later part, and when the stalks are cut, the cutting length of the stalks is controllable and uniform without whole leaves, so that the quality of the stalks is improved; when the straw is completely reserved, the straw is bundled or laid orderly, the straw is more adaptive to different requirements of downstream production, and the recycling rate of the straw is improved;
8) The modular design of the harvesting unit provides conditions for realizing standardized production of parts and reducing production cost;
9) Different types of cutting machine can be realized by combining different numbers of the harvesting units; the combination of different directions can obtain the machine type which completely retains different harvesting results of grass cutting and the like.
