Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sunflower harvesting, and particularly relates to a sunflower harvesting platform. Background Art
[0002] The sunflower harvesting process mainly includes steps such as cutting the disk and inserting it, drying, threshing, and screening. Currently, each step is mostly manually operated. Among them, for cutting the disk and inserting it, sunflower farmers use sickles to cut the sunflower disk from the sunflower stalk, cut the top end of the sunflower stalk into a tip, trim the disk pedicle, and insert it on the tip of the sunflower stalk on the ground for drying. The purpose of this step is to remove the moisture in the sunflower and prepare for threshing.
[0003] At the present stage, cutting the disk and inserting it is mostly manually operated. Especially during the disk cutting process, two to three cuts are required. The first cut is to cut the sunflower disk from the sunflower stalk. A skilled worker can also remove the disk pedicle (the connection between the sunflower disk and the sunflower stalk) at the same time. Removing the disk pedicle facilitates inserting the bottom of the sunflower disk on the tip of the sunflower stalk. The second cut is to cut the end of the sunflower stalk on the ground into a tip, and then insert the bottom of the sunflower disk on the tip. A novice may need a third cut, that is, trimming the disk pedicle, and even a fourth cut to trim the tip of the sunflower stalk on the ground. Manual disk cutting has a high labor intensity and also requires a high proficiency of the operator. Therefore, the efficiency of disk cutting is not easy to improve, and there is also a safety hazard of accidental injury during disk cutting.
[0004] Currently, there are a small number of harvesting platform devices dedicated to sunflowers that can perform the above operations. The sunflower dedicated harvesting platform is installed at the front end of a walking vehicle such as a tractor. When the walking vehicle moves forward, the sunflower stalks are cut using the sunflower dedicated harvesting platform, and the sunflowers are harvested. However, there are still defects in actual use. Often, there will still be a small amount of sunflower stalks or disk pedicles remaining at the bottom of the cut sunflower disk, resulting in the bottom of the sunflower disk bulging outwards and having obstacles. When inserting the disk, it is easy to insert it crooked or require multiple insertions, and the process is not smooth, affecting the efficiency and also damaging the sunflower disk.

[0023] Embodiment:
[0024] As Figures 1 to 7 shown, a sunflower header includes a header 1, a chain mechanism 2, a cutting knife 3 and a pedicel cutting knife 4. A material guiding groove 5 arranged along the traveling direction of the walking vehicle is provided on the header 1. Chain mechanisms 2 that rotate relatively backward are rotatably provided at the bottom of the header 1 on both sides of the material guiding groove 5, and the chain mechanisms 2 are arranged along the length direction of the material guiding groove 5. A lever 2.1 is fixed to the outside of the chain of the chain mechanism 2, and the lever 2.1 is movably arranged at the lower part of the material guiding groove 5;
[0025] The two chain mechanisms 2 rotate relatively backward, and the chains of the chain mechanisms 2 drive the push rods 2.1 to move backward as well. When the sunflower stalks enter the material guiding groove 5, they are pushed backward by the push rods 2.1 and move backward along the material guiding groove 5.
[0026] At the bottom of the cutting table 1 on one side of the front end of the material guiding groove 5, a cutting knife 3 is rotatably provided and is inclined obliquely upward backward. And a cutting drive 6 for driving the cutting knife 3 to rotate is provided at the bottom of the cutting table 1; one side of the cutting knife 3 is rotatably provided below the material guiding groove 5;
[0027] The cutting knife 3 is inclined obliquely upward backward by about 45°. The purpose is to obliquely cut the sunflower stalks so that the top end of the sunflower stalks on the ground is an oblique end face, presenting a tip, which is convenient for the insertion of the sunflower disc. At the same time, the oblique end face of the top end of the sunflower stalks faces away from the walking vehicle. When the walking vehicle rubs against the oblique end face of the top end of the sunflower stalks and bends them during the forward movement, it can protect the tip; The cutting drive 6 is a cutting gear commutator, and its output end is fixed to the cutting knife 3.
[0028] At the bottom of the cutting table 1 corresponding to the rear end of the material guiding groove 5, a pedicel cutting knife 4 is rotatably provided. The pedicel cutting knife 4 is arranged above the chain mechanism 2. The pedicel cutting knife 4 includes two relatively rotating plum blossom cutter discs 4.1, and the two plum blossom cutter discs 4.1 partially overlap below the material guiding groove 5;
[0029] When the sunflower disc moves backward along the material guiding groove 5, it is sheared by the two plum blossom cutter discs 4.1 of the pedicel cutting knife 4, and the disc pedicel at the bottom of the sunflower disc is cut off. At the same time, relying on the force of the two plum blossom cutter discs 4.1 rotating relatively backward, the sunflower disc is transmitted to the rear.
[0030] A pedicel drive 7 for driving the pedicel cutting knife 4 to rotate is provided at the bottom of the cutting table 1. The pedicel drive 7 includes two pedicel chains and four pedicel sprockets. One pedicel chain and two pedicel sprockets form a group, and each group of two pedicel sprockets is driven by one pedicel chain.
[0031] On both sides of the bottom of the cutting table 1 of the material guiding groove 5 between the pedicel cutting knife 4 and the cutting knife 3, a cutting roller 8 arranged parallel to the material guiding groove 5 is rotatably provided respectively. A cutting roller drive 9 for driving the cutting roller 8 to rotate is provided at the bottom of the cutting table 1. The two cutting rollers 8 are rotatably arranged relatively below the chain mechanism 2, and the cutting edges of the two cutting rollers 8 are in movable contact.
[0032] During the process of the sunflower disc and the sunflower stalk moving backward along the material guiding groove 5 and before being sheared by the pedicel cutting knife 4, the redundant sunflower stalks at the bottom of the sunflower disc can be cut off by the two relatively downward rotating cutting rollers 8. And the sunflower disc and the sunflower stalks are also pulled downward, removing the sunflower stalks and leaving the sunflower disc on the cutting table 1, which is beneficial for the pedicel cutting knife 4 to cut the disc pedicel of the sunflower disc; The cutting roller drive 9 is a total gear commutator, which has a pair of horizontal output ends and is coaxially fixed to the two cutting rollers 8.
[0033] Above the cutting platform 1 on one side of the material guide trough 5, an inverted auger 10 is rotatably provided and arranged along the length direction of the material guide trough 5. The front end of the inverted auger 10 extends to the front of the material guide trough 5. Above the cutting platform 1, an auger drive 11 is provided to drive the inverted auger 10 to rotate.
[0034] The inverted auger 10 is conical in shape, with its narrow tip rotatably connected to the cutting table 1, and its wide round end coaxially fixed to the output end of the auger drive 11 through a universal joint. The inverted auger 10 is set obliquely downward, with its narrow tip facing the front of the guide trough 5. During the backward movement of the sunflower disc and sunflower stem along the guide trough 5, the sunflower disc will fall due to gravity and can be supported by the inverted auger 10 to the top of the guide trough 5; the auger drive 11 is an auger gear commutator.
[0035] like Figure 7 As shown, the power mode of the sunflower harvesting platform of this embodiment is realized by the driving device of the traveling vehicle: the driving device of this embodiment is selected as an engine, and the transmission rod of the engine provides power output, which is transmitted to the input end of the auger drive 11, the input end of the cutting drive 6, and the input end of the cutting roller drive 9 through the sprocket and chain;
[0036] The cutting roller drive 9 has a pair of output ends at the top longitudinally, which are coaxially fixed with the sprockets of the chain mechanism 2 and the two groups of sprockets of the cutting roller drive 7.
[0037] Working principle: The sunflower harvesting platform in this embodiment has a structural design suitable for planting sunflowers in multiple groups side by side, with each group consisting of two rows of sunflowers, and several sunflowers arranged at intervals in each row; the sunflower harvesting platforms are grouped into two groups, adapted to the two rows of sunflowers in a corresponding group.
[0038] The sunflower harvesting platform of this embodiment is advanced by the traveling vehicle, and the sunflower stalks of a single row of sunflowers enter the guide chute 5 and are moved backward by the shifting rods 2.1 of the two chain mechanisms 2. At the same time, the inverted supporting auger 10 supports the sunflower disc that has tilted due to gravity to the top of the guide chute 5; after entering the guide chute 5, first, the cutting knife 3 cuts off the sunflower stalks, and the cut sunflower discs and stalks continue to move in the guide chute 5. At the same time, the excess sunflower stalks at the bottom of the sunflower disc can be cut off by two cutting rollers 8 that rotate downward relative to each other, and the sunflower discs and stalks are also dragged downward, the sunflower stalks are removed, and the sunflower discs remain on the harvesting platform 1. Then, the sunflower discs are sheared by the two plum blossom knife discs 4.1 of the stem cutting knife 4, and the stems at the bottom of the sunflower disc are cut off. At the same time, the sunflower discs are transmitted to the rear by the force of the two plum blossom knife discs 4.1 rotating relatively backward.
[0039] The sunflower harvesting platform of the present utility model uses the push rod 2.1 of the chain mechanism 2 to send sunflower stalks and sunflower heads into the material guiding groove 5. When passing through the material guiding groove 5, the sunflower stalks and sunflower heads are first cut by the cutting knife 3, and then the redundant sunflower stalks attached to the sunflower head are removed by the cutting roller 8. Finally, the stalk base is cut off by the stalk base cutting knife 4 to trim the bottom of the sunflower head, making the bottom of the sunflower head flat, facilitating the insertion of the tray, improving the efficiency, and reducing the damage to the sunflower head.
[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
