Description

Technical Field

[0001] The present invention relates to a multi-functional operation platform for forage harvesting and flattening, in particular to a precisely controlled multi-functional operation platform for forage harvesting and flattening, belonging to the technical field of forage machinery. Background Art

[0002] In the prior art, for example, in the invention with the application number 202211591518.8, a mowing and flattening machine is disclosed. In order to solve the problems of re-cutting and grass fragmentation during the harvesting operation of the mowing and flattening machine, especially to solve the problem of a relatively high grass fragmentation rate when the existing mowing and flattening machine harvests lodging forage, the auxiliary harvesting system can optimize the airflow field in the cutting and flattening area of the mowing and flattening system, improve the shape and position attitude of the forage and the cutting and conveying process, reduce the grass fragmentation rate during the harvesting process, improve the harvesting quality of the mowing and flattening machine, and further improve the quality of the grass products. ② The airflow field of the lodging suction unit can change the shape and position attitude of the lodging forage in front of the cutter, so that the lodging forage is in an upright or semi-upright state at the moment of cutting, avoiding the cutter cutting the upper part of the plant and causing grass fragmentation. ③ The second air suction member uses the airflow to suck up the plants cut by the cutter backward and upward. On the one hand, it can quickly move the cut plants away from the cutter, avoid re-cutting and thus reduce the grass fragmentation rate. On the other hand, it can quickly move the cut plants close to the flattening unit, reduce blockage, and ensure smooth feeding.

[0003] Similar to the above application, there are still deficiencies at present:

[0004] Due to the different density and lying conditions of the forage, it is difficult to lift the forage that is severely attached to the ground and has a low planting density by means of negative pressure suction, resulting in the cutter being unable to harvest the forage, affecting the use effect. And during the negative pressure suction process, it is necessary to be close to the forage to ensure sufficient suction. If the lodging state of the forage is different, it is necessary to frequently adjust the position of the suction port, which is inconvenient to use. In addition, during the harvesting process, the cutter is at a relatively low position, and obstacles such as stones and tree roots may damage the cutter, affecting the cutting effect.

[0005] Therefore, a precisely controlled multi-functional operation platform for forage harvesting and flattening is designed to optimize the above problems. Summary of the Invention

[0006] The main object of the present invention is to provide a precise control forage harvesting and flattening multi-functional operation platform. A plurality of groups of turntables are evenly arranged at the front end of the frame, and cross bars are evenly arranged in an annular array between adjacent turntables. The cross bars protrude outside the turntables. During use, the adjustment mechanism is used to adjust the use height of the cross bars and the distance between the cross bars and the cutting table according to the length of the forage. The rotation of the cross bars is controlled by a motor, and then the fitting component is used to ensure that the cross bars can fit the terrain after rotating to the lowest end according to the terrain. When the device is in use, the device is driven by an agricultural machine to move in the direction of the fallen forage. The plurality of cross bars rotate counterclockwise, and the forage can be lifted so that the cutter can perform the harvesting operation, which has higher practicability. Through the fitting mechanism composed of a chute, a slider, a spring, and a support rod, during the rotation of the cross bar, if it encounters a raised ground, the ground exerts a reverse pressure on the cross bar, squeezing the spring and adjusting the position of the cross bar to ensure that the cross bar fits tightly against the ground and the effect of lifting the forage during rotation.

Through the pushing mechanism composed of a vertical plate, a third shaft rod, a dial rod, a pulley assembly, a scraper, and a scraping groove, after the forage is lifted and cut, it can be quickly pushed towards the frame direction, and the forage enters between the pressure rollers for flattening operation, avoiding the fallen forage directly sticking to the ground and ensuring the flattening effect during use.

[0042] To make the technical solution of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below in conjunction with embodiments and drawings. However, the implementation manners of the present invention are not limited thereto.

[0043] As Figures 1-8 shown, this embodiment provides a precise control forage harvesting and flattening multi-functional operation platform, including a frame 1, a pressure roller 101 rotatably installed on the frame 1, which includes two sets of opposed corrugated pressure rollers up and down. The surface of the pressure roller 101 is provided with spiral raised lines with a spacing of 10 - 15 mm and a depth of 5 - 8 mm, and reverse rotation is achieved through gear transmission with a speed ratio of 1.2:1. A cutting table 102 fixedly installed at the bottom of the frame 1 and a cutter 103 installed on the top of the cutting table 102. The device is installed on a tractor and uses the tractor to provide power and drive for the cutter 103 and the pressure roller 101.

[0044] For the specific structures of the suspension assembly, drive components of the frame 1 and the tractor, and the cutter 103, reference can be made to Patent 201610507487.1, a disc mower with a flattening function, and the authorized announcement number is CN106034539B. This application will not elaborate.

[0045] A first shaft rod 3 is arranged parallel to the length direction of the frame 1 at the front end of the frame 1. A turntable 2 is evenly fixed on the first shaft rod 3, and the first shaft rod 3 passes through the center of the turntable 2. Cross bars 4 are evenly arranged in an annular array between adjacent turntables 2, and the cross bars 4 protrude outside the turntable 2. A fitting mechanism 5 for controlling the radial movement of the cross bar 4 along the turntable 2 is provided on the turntable 2.

[0046] An adjusting mechanism 6 is provided between the top of the frame 1 and the turntable 2. The adjusting mechanism 6 controls the up and down movement and horizontal expansion and contraction of the turntable 2. A motor 7 for driving the rotation of the turntable 2 is provided on the adjusting mechanism 6, and a pushing mechanism 8 for conveying forage towards the frame 1 is provided below the adjusting mechanism 6.

[0047] Overall working principle: Before harvesting severely lodged forage, the tractor drives the frame 1 to move beside the forage, with the front end of the frame 1 facing the lodging direction of the forage. First, use the adjustment mechanism 6 to control the translation of the turntable 2 and the crossbar 4, ensuring that the distance between the crossbar 4 and the cutting table 102 is greater than the total length of the forage when the crossbar 4 is directly below the turntable 2. Then, use the adjustment mechanism 6 to control the crossbar 4 to move downward until it touches the top of the forage. At this time, the crossbar 4 will be at the front end of the lodged forage. When harvesting severely lodged forage, the tractor drives the device to move, and uses the motor 7 to control the crossbar 4 on the turntable 2 to rotate counterclockwise. During the rotation of the crossbar 4, the forage can be lifted towards the direction of the frame 1, and the root of the forage is cut off by the cutter 103 during the lifting process. After cutting, use the pushing mechanism 8 to convey the forage to the middle of the pressure roller 101, and then flatten and discharge the forage. In addition, during the rotational movement of the crossbar 4, if there are bumps on the ground, the setting of the fitting mechanism 5 ensures that the crossbar 4 can extend and contract along the radial direction of the turntable 2 for a certain length, ensuring that the crossbar 4 can rotate and move stably and closely adhere to the top of the forage to better right the forage.

[0048] In this embodiment, guiding rods 9 are evenly arranged at the front end of the cutting table 102. The front ends of multiple groups of guiding rods 9 are conical, and the length of the guiding rod 9 at the middle position of the front end of the cutting table 102 is greater than that at both ends.

[0049] Local working principle: During the process of forage harvesting, if encountering obstacles such as stones and tree roots, the guiding rods 9 can block their continuous advancement to prevent damage to the cutter 103. In addition, the conical structure of the guiding rods 9 can guide the obstacles to the side.

[0050] In this embodiment, the fitting mechanism 5 includes a chute 501, a slider 502, a spring 503, and a support rod 504. The chutes 501 are evenly opened on the opposite sides of the turntable 2 and are distributed in a circular array. The chutes 501 are perpendicular to the cutting plane of the turntable 2. Sliders 502 are slidably arranged inside the chutes 501. Springs 503 are provided between the sides of the sliders 502 close to the center of the turntable 2 and the inner ends of the chutes 501. Support rods 504 are fixed to the outer sides of the sliders 502. The support rods 504 are parallel to the length direction of the chutes 501. The crossbar 4 is fixedly installed between the support rods 504 at the corresponding positions on the turntable 2. The chutes 501 have a "T-shaped" or "dovetail-shaped" cross-section, and the sliders 502 are correspondingly provided with matching grooves to ensure that the sliders 502 slide linearly along the radial direction of the turntable 2 and prevent them from slipping out.

[0051] Local working principle: When the cross bar 4 encounters a raised ground condition during rotation, since the horizontal height of the turntable 2 is fixed, even if the raised ground squeezes the cross bar 4, the cross bar 4 will control the slider 502 to slide inside the chute 501 and squeeze the spring 503. And during the movement of the cross bar 4, it will always be in contact with the top of the forage grass to ensure the effect of righting the forage grass. After passing over the raised area, the cross bar 4 will quickly reset under the elastic force of the spring 503.

[0052] In this embodiment, the cross-sectional shape of the end of the cross bar 4 is an equilateral triangle, and the tip of the cross bar 4 is inclined away from the turntable 2, and the side of the cross bar 4 is coated with a wear-resistant coating.

[0053] Local working principle: During the rotation of the cross bar 4, the tip of the cross bar 4 will move towards the front end of the forage grass, making it easier to enter under the end of the forage grass to lift the forage grass.

[0054] In this embodiment, the adjusting mechanism 6 includes a fixed block 601, a second shaft rod 602, a sliding sleeve 603, a cross plate 604, a mounting bracket 605, a pin shaft 606, a first hydraulic cylinder 607, a sliding rod 608 and a translation assembly. The fixed blocks 601 are fixed at both ends of the top of the frame 1. A second shaft rod 602 is rotatably installed between the two groups of fixed blocks 601. Sliding sleeves 603 are symmetrically installed at both ends of the second shaft rod 602. A cross plate 604 is fixed between the two groups of sliding sleeves 603. A mounting bracket 605 is installed at the middle position of the top of the frame 1. A pin shaft 606 is rotatably installed on the mounting bracket 605. A first hydraulic cylinder 607 is installed on the pin shaft 606. The output end of the first hydraulic cylinder 607 is hinged to the top of the cross plate 604. Sliding rods 608 are slidably installed inside the sliding sleeves 603. The surface of the sliding rod 608 is processed into a smooth cylindrical surface or a rectangular guide rail surface to ensure smooth horizontal sliding. Both ends of the first shaft rod 3 are rotatably installed between the ends of the sliding rods 608. The motor 7 is installed at the end of the sliding rod 608. The output end of the motor 7 is connected to the end of the first shaft rod 3. A translation assembly is provided between the sliding sleeve 603 and the sliding rod 608.

[0055] Local working principle: When harvesting forage grass in a normal growth state, start the first hydraulic cylinder 607, and the sliding sleeve 603 rotates around the second shaft rod 602, and the turntable 2 and the cross bar 4 move up above the forage grass, so as not to cause obstruction during the mowing process. When harvesting lodged forage grass, first use the translation assembly to adjust the positions of the turntable 2 and the cross bar 4 to ensure that the distance between the bottommost cross bar of the turntable 2 and the cutting table 102 is greater than the length of the forage grass. Then start the first hydraulic cylinder 607 to control the turntable 2 and the cross bar 4 to rotate downward until the bottommost cross bar 4 of the turntable 2 is in contact with the surface of the forage grass.

[0056] In this embodiment, the shape of the sliding rod 608 is V-shaped, and the end of the sliding rod 608 away from the sliding sleeve 603 is bent downward. A reinforcing plate is provided at the corner of the sliding rod 608.

[0057] Local working principle: The front end of the sliding rod 608 is reinforced by the reinforcing plate, which improves the strength of the front end and avoids the deformation of the sliding rod 608.

[0058] In this embodiment, the translation assembly includes a fixed plate 609 and a second hydraulic cylinder 610. The fixed plate 609 is fixed between the two sliding rods 608. Second hydraulic cylinders 610 are installed at both ends of the top of the cross plate 604, and the output ends of the second hydraulic cylinders 610 are fixedly connected to the top of the fixed plate 609.

[0059] Local working principle: When it is necessary to translate the turntable 2 and the cross bar 4, start the second hydraulic cylinder 610 to horizontally control the movement of the sliding rod 608, and then adjust the positions of the turntable 2 and the cross bar 4.

[0060] In this embodiment, the pushing mechanism 8 includes a vertical plate 801, a third shaft 802, a lever 803, a pulley assembly 804 and a scraping assembly. The vertical plate 801 is fixed below the sliding rod 608. A third shaft 802 is rotatably installed between the two sliding rods 608. Levers 803 are evenly arranged along the circumference on the outer side of the third shaft 802, and the levers 803 are equally spaced along the length direction of the third shaft 802. The lever 803 is bent, and its length is 1 / 3 to 1 / 2 of the average height of the forage grass, ensuring that the lever 803 can effectively hook the forage grass stalks. Anti-slip tooth patterns are provided on the surface of the lever 803, with a tooth pattern spacing of 5 to 10 mm and a depth of 2 to 3 mm to enhance the grasping force on the forage grass. A pulley assembly 804 is provided between the end of the third shaft 802 and the output end of the motor 7. A scraping assembly for cleaning the surface of the lever 803 is provided at the top of the vertical plate 801 close to the frame 1.

[0061] Local working principle: After cutting off the roots of the forage grass, the forage grass is not in a vertical state at this time. In order to prevent the forage grass from sticking to the ground again or being crushed by the cutter 103 again, the motor 7 cooperates with the pulley assembly 804 to drive the rotation of the third shaft 802. The third shaft 802 and the lever 803 also rotate counterclockwise to push the forage grass towards the frame 1 for convenient and rapid flattening. The bent design of the lever 803 can improve the contact effect with the forage grass and effectively prevent slipping.

[0062] In this embodiment, the pulley assembly 804 includes a driven pulley 8041, a driving pulley 8042 and a belt 8043. The driven pulley 8041 is installed at the end of the third shaft 802, the driving pulley 8042 is installed at the output end of the motor 7, and a belt 8043 is provided between the driven pulley 8041 and the driving pulley 8042.

[0063] Local working principle: When the motor 7 controls the rotation of the turntable 2, it simultaneously drives the driving wheel 8042 to rotate. The driving wheel 8042 cooperates with the belt 8043 to control the rotation of the driven wheel 8041, thereby driving the third shaft rod 802 and the lever 803 to rotate.

[0064] In this embodiment, the scraping assembly includes a scraper 805 and a scraping groove 806. The scraper 805 is inclined between two sets of vertical plates 801, and the bottom end of the scraper 805 is inclined towards the direction of the frame 1. The angle between the scraper 805 and the horizontal plane is 30° - 45°, and the bottom end is 5 - 10 mm away from the lowest point of the rotation trajectory of the lever 803, avoiding interference while ensuring the scraping effect. The bottom end of the scraper 805 is evenly provided with a scraping groove 806 for the lever 803 to pass through along the length direction. The width of the scraping groove 806 is 2 - 3 mm larger than the diameter of the lever 803, and the depth is the same as the thickness of the bent part of the lever 803, ensuring that the forage is completely peeled off by the edge of the scraping groove 806 when the lever 803 rotates.

[0065] Local working principle: During the rotation of the lever 803, the situation of forage adhesion may occur. When the lever 803 passes through the scraping groove 806, the scraping groove 806 can scrape off the forage on the lever 803, avoiding the adhesion of the forage.

[0066] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent replacements or changes, all belong to the protection scope of the present invention.
