Description

Technical Field

[0001] This invention relates to the field of forage stripping technology, and in particular to a method for controlling forage stripping. Background Technology

[0002] Currently, hay splitting and core stripping is still mainly done manually, and automated production has not been achieved. Manual splitting and core stripping can only be done on a single haystack at a time, which is inefficient. At the same time, the tools used by manual labor are dangerous and prone to accidents, and the quality of products produced by operators is also inconsistent. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide a method for controlling the removal of straw cores, thereby solving the problem of low efficiency in existing manual straw core removal methods.

[0004] To address the aforementioned technical problems, this invention provides a method for controlling forage core stripping, comprising: S1. Align the roots of the hay and stack them neatly in the hay trough; S2. The suction ports of the parallel suction rods are pressed against the root and stem parts of the grass in the grass trough to suck up the grass and move it to the top of the conveying and cutting platform. S3. The roots and stems of the grass are released by the adsorption rod to the grass heating guide trough on the conveying and cutting platform. The grass heating guide trough is controlled to heat the grass roots and stems inside, so that the surface of the grass roots and stems and the leaves are partially dehydrated. Then the adsorption rod leaves the conveying and cutting platform and returns to the top of the grass trough. S4. Control the drive platform to descend to near the conveying and cutting platform, and then start the drive device on the drive platform to drive the grass to move forward along the grass heating guide groove, so that the upper part of the grass is first cut by the first cutting blade at the end of the drive platform, and the lower part of the grass is cut by the second cutting blade on the conveying and cutting platform as the grass continues to move forward, so that the leaves outside the root and stem separate to both sides of the grass core. S5. The cut grass roots and grass cores are conveyed forward to the support groove wheel at the end of the conveying and cutting platform. After passing the support groove wheel, the center of gravity of the grass core causes the grass core roots to tilt downward due to gravity, the middle part to be supported by the support groove wheel, and the tip to curl upward. S6. The horizontal suction tube on the drive platform provides a backward and upward suction force to the upper and lower part of the grass core, causing the grass core to tilt backward and upward into the suction tube to separate from the outer skin of the grass, while the outer skin of the grass continues to be conveyed forward. S7. Repeat steps S2 to S6.

[0005] The forage core stripping control method provided by the present invention may further include S8, collecting and drying the forage core.

[0006] Step S2 includes: detecting the amount of hay in the hay trough using a gravity sensor or visual recognition; when the hay in the hay trough is empty or insufficient, replenishing the hay trough and aligning the hay roots with the roots facing forward under the suction rod so that the suction rod can pick up the hay roots; replenishing the hay trough is achieved by feeding it with external equipment, for example: placing the bundled hay bales in the hay trough by lifting and lowering, and then opening the binding structure on the hay bales; or after aligning the hay, conveying it into the hay trough from the top or side.

[0007] Step S2 further includes: detecting the distance H between the material taking device and the grass below by distance recognition, then controlling the adsorption rod to move down (1-k)H+kH0 and press it behind the root of the grass (more precisely, the position of the grass core, which is a distance away from the root of the grass), and then starting the blower to generate negative pressure suction at the front adsorption port of the adsorption rod, so that the front adsorption port adsorbs the grass stem; H0 is the distance between the initial position of the adsorption rod and the bottom of the grass trough. The downward movement distance of the material taking device is set as H+k(H0-H)=(1-k)H+kH0, where H0-H is the thickness of the grass, k(H0-H) is the degree of compaction of the grass, k is the compaction coefficient of the grass, which is the ratio between the compacted thickness d and the original thickness D. The compacted grass stem remains intact and undamaged.

[0008] Step S2 also includes: controlling the adsorption rod to lift the adsorbed grass upward to a height higher than the grass trough, then controlling the adsorption rod to carry the grass horizontally to above the conveying and cutting platform, and then controlling the adsorption rod to descend to approach the conveying and cutting platform.

[0009] Step S3 includes positioning the bottom of the straw directly opposite the straw heating guide groove, then turning off the blower to detach the front suction port of the material taking device from the straw, and letting the straw fall into the straw heating guide groove of the conveying and cutting platform under gravity, controlling the suction rod to return to the top of the straw groove; at the same time, controlling the conveying and cutting platform to hold the root of the straw and convey it forward.

[0010] Step S4 includes controlling the gap between the drive platform and the hay heating guide groove to prevent the hay blades from being ground up.

[0011] The adsorption rod is controlled to move in the vertical and horizontal directions by a vertical telescopic rod and a horizontal moving frame.

[0012] The forage core stripping control method provided by this invention enables rapid forage core stripping. During the stripping process, heating dehydrates the outer skin, making the difference in moisture content between the outer skin and the core more pronounced. The design of two cutting blades (upper and lower) allows for overall cutting of the forage outer skin while maintaining the integrity of the core, facilitating separation. The support of the grooved wheel ensures complete separation of the core from the outer skin, and the core's center of gravity and weight cause it to tilt. This results in... The outer skin with low moisture content is more easily separated from the grass core after being cut from top to bottom, while the grass core with high moisture content retains its integrity. As a result, when passing through the support groove wheel, the grass core and the outer skin form completely different movement paths. The outer skin is very light due to dehydration and will not tilt significantly, while the grass core, due to its own weight and integrity, tilts due to the support groove wheel, so as to be sucked by the suction tube. This achieves complete separation of the grass core and the outer skin, improves the efficiency of grass core stripping, and the separated outer skin does not need to be dehydrated again before baling.

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] like Figure 1-2 As shown, the present invention provides a method for controlling forage core stripping, comprising: S1. Align the roots of the hay and neatly stack them in the hay trough; the hay trough is rectangular in shape with a concave interior to form a space to hold the hay; the left end of the hay trough can be designed as an openable structure (such as a flip door, a lift door, or other conventional structural designs) so that the hay can be fed into the hay trough horizontally. S2. The suction ports of the parallel suction rods press against the root and stem parts of the forage in the forage trough 2, sucking up the forage and moving it above the conveying and cutting platform. Multiple suction rods are arranged horizontally in a parallel row, with 2-3 suction ports at the bottom of each rod, allowing for multi-point suction of the forage's root and stem parts. Each suction port is connected to a blower pipe, creating negative pressure suction when the blower is started. The suction ports can be fitted with rubber pads or soft materials to ensure close contact with the forage's root and stem parts, facilitating suction. The suction rods are also connected to a vertical moving mechanism to allow vertical movement. This vertical moving mechanism is also connected to a horizontal moving mechanism, enabling horizontal movement of both the suction rods and the vertical moving mechanism. Both the vertical moving mechanism (e.g., vertical telescopic rod 3) and the horizontal moving mechanism (e.g., horizontal moving frame 4) can utilize conventional guide rail drive mechanisms. S3. The roots and stems of the forage are released by the adsorption rod to the forage heating guide 6 on the conveying and cutting platform. The forage heating guide 6 is controlled to heat the roots and stems of the forage inside, so that the surface of the roots and stems and the leaves of the forage are partially dehydrated. Then the adsorption rod leaves the conveying and cutting platform and returns to the top of the forage trough. The forage heating guide 6 is equipped with a heating device inside, which can heat the forage. The upper part of the forage heating guide 6 is provided with a longitudinal guide trough with a V-shaped opening to accommodate the roots and stems of the forage. The conveying and cutting platform is equipped with multiple recessed and longitudinally arranged grass heating guide grooves that correspond one-to-one with the adsorption rods, allowing the grass adsorbed by the adsorption rods to be lowered into the grass heating guide grooves. The length of the grass heating guide grooves should be greater than the length of the grass root and stem parts, so that the main part of the grass can enter the grass heating guide grooves. The driving device can be a conventional drive belt (such as a conveyor belt), which presses against the grass heating guide grooves of the conveying and cutting platform, thereby driving the grass to move forward along the grass heating guide grooves during the drive of the drive belt. S4. Control the drive platform 7 to descend to near the conveying and cutting platform, then activate the drive device 8 on the drive platform to drive the straw forward along the straw heating guide groove. The upper part of the straw is first cut by the first cutting blade 12 at the end of the drive platform, and the lower part is then cut by the second cutting blade 13 on the conveying and cutting platform as the straw continues to move forward, causing the leaves outside the rootstock to separate towards both sides of the straw core. The drive platform 7 can move vertically along the guide rail to drive the drive device 8 and the suction pipe 9. The height of the suction pipe 9 is slightly higher than the bottom surface of the drive device 8, allowing for suction of the straw core from a higher position, avoiding accidental suction of the straw outer layer. The first cutting blade 12 and the second cutting blade 13 cut the straw outer layer successively, ensuring that the straw reaches the support groove wheel. S5. The cut grass roots and grass cores are conveyed forward to the support groove wheel 14 at the end of the conveying and cutting platform. After passing the support groove wheel, the center of gravity of the grass core causes the grass core roots to tilt downwards due to gravity, the middle part to be supported by the support groove wheel, and the tip to curl upwards. S6. The horizontal suction tube on the drive platform provides a backward and upward suction force to the upper and lower part of the grass core, causing the grass core to tilt backward and upward into the suction tube to separate from the outer skin of the grass, while the outer skin of the grass continues to be conveyed forward. S7. Repeat steps S2 to S6.

[0019] The forage core stripping control method provided by the present invention may further include S6, collecting and drying the forage core.

[0020] Step S2 includes: detecting the amount of hay in the hay trough using a gravity sensor or visual recognition; when the hay in the hay trough is empty or insufficient, replenishing the hay trough and aligning the hay roots with the roots facing forward under the suction rod so that the suction rod can pick up the hay roots; replenishing the hay trough is achieved by feeding it with external equipment, for example: placing the bundled hay bales in the hay trough by lifting and lowering, and then opening the binding structure on the hay bales; or after aligning the hay, conveying it into the hay trough from the top or side.

[0021] Step S2 further includes: detecting the distance H between the material taking device and the grass below by distance recognition, then controlling the adsorption rod to move down (1-k)H+kH0 and press it behind the root of the grass (more precisely, the position of the grass core, which is a distance away from the root of the grass), and then starting the blower to generate negative pressure suction at the front adsorption port of the adsorption rod, so that the front adsorption port adsorbs the grass stem; H0 is the distance between the initial position of the adsorption rod and the bottom of the grass trough. The downward movement distance of the material taking device is set as H+k(H0-H)=(1-k)H+kH0, where H0-H is the thickness of the grass, k(H0-H) is the degree of compaction of the grass, k is the compaction coefficient of the grass, which is the ratio between the compacted thickness d and the original thickness D. The compacted grass stem remains intact and undamaged.

[0022] Step S2 also includes: controlling the adsorption rod to lift the adsorbed grass upward to a height higher than the grass trough, then controlling the adsorption rod to carry the grass horizontally to above the conveying and cutting platform, and then controlling the adsorption rod to descend to approach the conveying and cutting platform.

[0023] Step S3 includes positioning the bottom of the straw directly opposite the straw heating guide groove, then turning off the blower to detach the front suction port of the material taking device from the straw, and letting the straw fall into the straw heating guide groove of the conveying and cutting platform under gravity, controlling the suction rod to return to the top of the straw groove; at the same time, controlling the conveying and cutting platform to hold the root of the straw and convey it forward.

[0024] Step S4 includes controlling the gap between the drive platform and the hay heating guide groove to prevent the hay blades from being ground up.

[0025] In step S4, the straw stalks are longitudinally cut by a cutting blade during the conveying process. The hay barn stripping control method provided by this invention can achieve rapid hay barn stripping and improve the efficiency of hay barn stripping.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
