Description

Device and method for processing corn stalks

technical field

The invention relates to the technical field of straw treatment, in particular to a corn straw treatment device and method.

Background technique

In the process of collecting corn stalks that are not used as silage, they are often collected after the corn is mature. At this time, the corn stalks have reached a certain degree of dryness, but the insides and roots of the stalks are still relatively fresh. When collecting straw in a large area of cultivated land, harvesters are generally used to collect straw while harvesting corn. For small plots, it is difficult for larger harvesters to enter, and often only rely on manual corn harvesting. Harvesting and processing of straw, and when collecting manually, the straw is often harvested with simple tools (such as hoes and sickles, etc.), and because the corn stalks and roots are still fresh at this time, it is difficult to remove It is uprooted, but cut off at the part near the root of the stem, and then the stems and leaves are collected and processed, while the roots are left in the soil and processed after it dries up naturally (usually after it dries up naturally) When the land is plowed before cultivation, the field will be used), and this method requires the cooperation of weather factors and regional factors. If it is affected by low terrain and rainy weather, it will be difficult for the roots in the land to dry up in time at this time, but they are not dry. After the root plowing into the land is not only easy to bring inconvenience to the next cultivation, such as affecting the sowing and soil covering operations of small seeders, but also the plant tissue with high water is easy to breed diseases and insect pests, which will easily cause the crops to be planted later. its shortcomings.

A control method of a corn stalk processing device in the present invention: In order to facilitate the description of the movement of parts, the following descriptions of the "clockwise" and "counterclockwise" rotation directions are all made in the right-view direction.

In the initial state, under the effect of no external force, the compression spring 49 at this time is in a slight elastic compression state under the effect of the weight of the parts above, and the two splints 28 are far away from each other, and the blade 42 of the left blade body 41 and the blade of the right blade body 40 The blade 42 is in a separated state. At this time, the push rod 16 is at the rear and lower part of the anti-slip strip 29. The lifting frame 20 is in contact with the top of the limit plate 21 under the elastic tension of the tension spring 23. The upper sector gear 6 is at the upper rack 24. Below, hold the grip 9 with both hands and press down slightly, then under the action of the upper sector gear 4 and the upper arc-shaped rack 6, the first gear 11, the first shaft 3, the second gear 12, and the third gear 27 Rotate clockwise with the two-way screw rod 25, and the clockwise rotation of the second gear 12 will use the rear rack 15 to make the sliding seat 14 slide forward, so that the push rod 16 will gradually move forward. Front and bottom, then hold the handle 9 to push the device backwards, then the direction of the splint 28 gradually tends to be perpendicular to the rear wheel shaft 52 and the front wheel shaft 53 under the effect of frictional resistance. Close to the corn stalk, so that the stalk part of the stalk enters between the two splints 28. Since the rear of the two splints 28 is flared, it can facilitate the entry of the straw. When it enters and is blocked by the No. 1 polished rod 26, The straw is just between the anti-slip strip 29 of the left splint 28 and the anti-slip strip 29 of the right splint 28, and the bottom of the straw is between the blade 42 of the left blade 41 and the blade 42 of the right blade 40. Now continue to press the handle 9 , the two splints 28 are gradually approaching, thereby realizing the clamping of the straw, and as the upper sector gear 4 continues to swing, the pair of upper racks 24 will be raised upwards, and at this time the upper sector gear 4 and the third gear 27 are disengaged , and then it can prevent the upper sector gear 4 from blocking the next third gear 27 to follow the upward movement of the lifting frame 20, thereby driving the lifting frame 20, the splint 28 and the straw to move upward together, so that the roots of the corn stalks can be pulled out from the soil and the distance between the handlebar 9 and the No. 1 shaft 3 is lengthened during manufacture, which can reduce the downward force of pressing down the handlebar 9 when pulling out the roots by utilizing the leverage effect, thereby saving more effort. In the process, the rear The downward pressure of support rod 5 to transmission rod 45 will utilize front rack 46, No. 4 gear 36, No. 4 shaft 33, upper bevel gear 35, lower bevel gear 37 and No. 5 shaft 34 to make No. 5 gear 38 and No. 6 gear 39 rotates, thereby utilizing the meshing of the fifth gear 38 and the lower sector gear 43 and the meshing of the sixth gear 39 and the lower arc-shaped rack 44 to realize the mutual approach of the left blade 41 rear portion and the right blade 40 rear portion, and then realize the pairing The straw is cut near the root, so as to realize the separation of the root and the stem. After the separation, the height of the handle 9 can be kept inconvenient, and then the support shaft 50 is used as the axis to rotate in a circumferential direction, thereby changing the horizontal position of the straw, and then loosen. Open the handle 9, the upper sector gear 4 can be restored to the initial vertical angle and height under the elastic repulsion of the compression spring 49, then the splint 28 has released the clamping state of the straw, and the push rod 16 It also protrudes to the back and lower part of the anti-slip strip 29, so that the stalks between the splints 28 can be pushed away from the support cylinder 1, and then the stalks can be controlled to fall sideways in a specified direction (for example, to the right side of the open space) and finally lie flat), so as to facilitate the separate collection and treatment of the stem part and the root part.

The above are preferred embodiments of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, without departing from the principle and spirit of the present invention, the changes, modifications, Alternatives and modifications still fall within the protection scope of the present invention.
