Technical Field
The application relates to the field of agricultural equipment, in particular to a vertical corn harvester header.
Background
The corn harvester is an agricultural implement for mechanically picking up corn, piling up corn, returning stalk to field, etc. Wherein the header is a main structure for the corn harvester to perform the operations of picking and returning to the field. The main technological process is as follows: the corn harvester feeds along the corn planting direction, and under the action of the snapping roll and the snapping plate, the corn ear handle is broken. The corn ear handles are pulled off through the shearing action of the snapping rolls, and the corn ears fall into the ear boxes. The cornstalk is cut off from the root by a cutter rotating at high speed and then enters a crushing mechanism to be crushed into fragments, and the crushed cornstalk naturally falls to the ground so as to realize returning to the field.
The cutting table of the existing corn harvester is usually provided with a seedling pulling chain driven by chain transmission, and the seedling pulling chain drives seedling pulling fingers to pull corn stalks to the position of a snapping roll so as to remove corn ears. The reel chain is usually meshed with a driving sprocket for providing power and a plurality of auxiliary sprockets for controlling the trend of the reel chain, and is also connected with a tensioning wheel through an elastic piece, and the reel chain is tensioned by the plurality of sprockets and the tensioning wheel together.
The inventor finds that, in the prior art, although the header of the corn harvester can achieve the effect of picking ears in the use process, the header of the prior art receives a large impact force due to direct contact of the seedling pulling chain with corn stalks, the tension of the seedling pulling chain is reduced or even damaged after long-term use, and when the seedling pulling chain needs to be replaced, a user needs to detach at least one chain wheel or tensioning wheel to detach the seedling pulling chain, so that the replacement and maintenance of the seedling pulling chain are inconvenient in use because of frequent detachment of the chain wheel.

Referring to fig. 7 and 8, the trash discharging structure 6 includes a discharging port 63 opened at a position at the bottom of the frame 1 corresponding to between the long stalk pulling roller 53 and the ear picking plate 51, and the corn stalks cut by the cutter blades 55 can be discharged out of the header of the corn harvester through the discharging port 63. The frame 1 is fixedly connected with a collecting bin 61 corresponding to the position below the ear picking plate 51, the collecting bin 61 of the frame 1 is rotationally connected with an auger 62, the auger 62 is connected to a power output shaft 2 through a gear box, the power output shaft 2 can drive the auger 62 to rotate, fan blades of the auger 62 are made of polyurethane materials, and the rotating directions of the fan blades of the auger 62 close to the positions at two ends are opposite. The collecting bin 61 of the frame 1 is provided with a collecting opening 64 corresponding to the middle position of the auger 62, and corn ears in the collecting bin 61 can be driven by the fan blades of the auger 62 to enter a storage structure of the next step through the collecting opening 64 of the collecting bin 61.
The embodiment of the application relates to a cutting table of a vertical corn harvester, which is implemented according to the following principle: the user starts the corn harvester, and the power output shaft 2 of the corn harvester is driven to rotate, and meanwhile, the corn harvester moves to drive a cutting table connected with the corn harvester to move. In this process, the user aligns each row of corn with five reel channels 31 formed by ten reel structures 3, so that the five rows of corn can enter the five reel channels 31 respectively. The user then drives the corn harvester to move, the corn stalks are guided by the crop dividers 41 into the five crop-pulling channels 31, respectively, and in the process, the crop-pulling fingers 38 on the outer circumferential surface of the crop-pulling chain 37 are abutted against the surfaces of the corn stalks and push the corn stalks into the crop-pulling channels 31. When the tail end of the corn stalk is abutted against the cutter 11, the cutter 11 which moves back and forth cuts off the corn stalk near the tail end, the corn stalk completely enters the stalk pulling channel 31, and under the clamping of the two corresponding stalk pulling chains 37 and the two corresponding stalk pulling frames 79, the corn stalk moves to the position of the stalk pressing frame 791 in a nearly vertical mode, the stalk pressing frame pushes the corn stalk to bend downwards at the position of the corn stalk near the top, so that the position of the corn stalk near the tail end is tilted upwards, and the corn stalk is rotated from the position near the ear picking plate 51 to the direction which is obliquely arranged upwards at the position far away from the ear picking plate 51. Then, the corn stalk end is first passed through the ear picking plate 51 and enters between the two long stalk pulling rolls 53, the auxiliary ear picking plates 54 on the peripheral surfaces of the two long stalk pulling rolls 53 clamp the corn stalk together through the gap between the side plates 542 of the two long stalk pulling rolls, and bite the corn stalk to move away from the cutter 11, in the process, the corn stalk bottom is continuously cut into fragments by the cutter 55 connected to the surface of the long stalk pulling rolls 53, and the cut corn stalk is discharged through the discharge outlet 63 of the frame 1. When the corn stalk growing ear position moves to the ear picking plate 51 position, the corn ears connected to the peripheral surface of the corn stalk are cut off by the inclined ear picking plate 51 through shearing force because the cross sectional area is significantly wider than the cross sectional area of the end of the corn stalk, then the corn ears fall down along the inclined ear picking plate 51 into the collecting bin 61, the corn ears move to the collecting port 64 position in the pushing and downloading collecting bin 61 of the auger 62 and the polyurethane flexible blade on the surface, and finally enter the storage structure from the collecting port 64. The other cornstalks are continuously cut and discharged by the cutting knives 55 on the surfaces of the two long drawn cornstalks. When the user needs to replace the straw pulling chain 37, the user only needs to extend the hexagonal screwdriver into the locking hole 761 of the connector 76, then the connector 76 is tilted out of the accommodating groove 71 of the straw pulling frame 32, so that the push rod 77, the connector 76 and the threaded connecting rod 75 are moved out of the accommodating groove 71 of the straw pulling frame 32, the push rod 77 is rotated towards the direction close to the threaded connecting rod 75, the push rod 77 can be prevented from abutting against the sliding key 72, the sliding key 72 drives the connecting frame 35 and the auxiliary wheel 36 to move towards the driving chain wheel 34, the straw pulling chain 37 is further prevented from being tensioned outside the auxiliary wheel 36 and the driving chain wheel 34, the user can take the straw pulling chain 37 off for replacement, if the straw pulling chain 37 with different lengths is replaced by the user, the user can rotate the connector 76 to enable the connector 76 to rotate around the threads of the threaded connecting rod 75, so that the connector 76 is moved away from or close to the driving chain wheel 34 along the length direction of the threaded connecting rod 75, the distance between the push rod 77 and the threaded connecting rod 75 is increased or decreased, and finally the push rod 77 pushes the sliding key 72 to move along the length direction of the straw pulling chain 32 and the auxiliary wheel 36 to move along the length direction of the straw pulling chain 37, and the length of the straw pulling chain 37 is not matched with the straw pulling chain 37, and the straw pulling chain 37 can be replaced by the user with the new straw pulling chain 37 and the straw pulling chain 37.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
