Description

Technical Field

[0001] This invention relates to the field of agricultural equipment, and more specifically, to a harvesting device for harvesting silage corn. Background Technology

[0002] Silage refers to the process of compacting and sealing fresh plant materials to isolate them from the outside air, creating an oxygen-deficient environment that leads to anaerobic fermentation and the production of organic acids. This process preserves the fresh plant materials for a long time without spoiling, reducing nutrient loss and facilitating digestion and absorption by animals.

[0003] Corn is an important raw material for silage. During silage production, it needs to be cut, collected, and then crushed or processed whole.

[0004] CN101779545B discloses a design method for a self-propelled harvester that combines corn silage harvesting with stalk and ear harvesting and straw return. The multi-purpose self-propelled harvester consists of a walking drive mechanism and a harvesting mechanism. A corn ear harvesting and corn stalk chopping unit and a grain bin are fixed to the harvesting mechanism. The harvesting mechanism is detachably connected to a corn ear crushing mechanism or a corn ear conveying mechanism via detachable connectors. This self-propelled harvester features a reasonable layout, compact structure, small size, and light weight. It is interchangeable and can perform silage, stalk and ear harvesting, or stalk chopping and return. It has a long operating time, high efficiency, low energy consumption, and can harvest in plots of varying sizes. The corn harvester directly scatters the chopped corn stalks back to the field through the corn stalk chopping unit. However, corn is planted relatively densely, making accurate chopping difficult. Designing a mechanism to crush the corn on both sides would facilitate easier chopping.

[0005] Currently, there is a lack of equipment that can move the corn to both sides and then cut it to facilitate collection. Summary of the Invention

[0035] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0036] This invention includes a base plate 7, a support assembly 2, a power assembly 4, and a toggle assembly 5. The support assembly 2 includes a base plate 26, which is fixedly connected to an L-plate 27. The toggle assembly 5 is disposed on the upper side of the horizontal plate of the L-plate 27. The toggle assembly 5 includes a mounting block 513, which is fixedly connected to a round-head plate 52. The round-head plate 52 is connected to symmetrical square plates 54, and the symmetrical square plates 54 are rotatably connected to blocks 53. The blocks 53 are fixedly connected to a ring 55. The round-head plate 52 is fixedly connected to a rotary motor 51. The output shaft of the rotary motor 51 passes through the round-head plate 52 and is fixedly connected to a guide post 511. The guide post 511 is disposed within a stepped frustum 57. One end of a spring 510 is fixedly connected to the guide post 511. The spring 510 is looped around the guide post 511 and is fixedly connected to the stepped frustum 57. A toggle rod 58 is fixedly connected to the edge of the stepped frustum 57. A hemisphere 59 is fixedly connected to the end of the toggle rod 58. A round-headed rod 56 is fixedly connected to the stepped frustum 57, and the round-headed rod 56 contacts the ring 55. A base plate 26 is fixedly connected to a base block 211. A stepped column 21 is fixedly connected to the stepped column 21. An arc plate 22 is fixedly connected to the arc plate 22. A limiting arc plate 23 is fixedly connected to the arc plate 22. The power assembly 4 includes symmetrical mounting arc plates 49. The symmetrical mounting arc plates 49 match the arc plate 22. Each of the symmetrical mounting arc plates 49 is provided with an arc groove 48. The limiting arc plate 23 is nested within the symmetrical arc groove 48. Each of the symmetrical mounting arc plates 49 is fixedly connected to a limiting vertical rod 412. Each of the symmetrical limiting vertical rods 412 is fixedly connected to a receiving plate 413. Each of the symmetrical receiving plates 413 is rotatably connected to an auxiliary toggle rod 411.

[0037] The power assembly 4 also includes a power motor 44, which is fixedly connected to the base block 211 via a motor bracket. The output shaft of the power motor 44 is fixedly connected to an L-axis 42. The round shaft of the L-axis 42 is set in a transverse groove 41. The two ends of the transverse groove 41 are respectively fixedly connected to racks 47. The stepped column 21 is fixedly connected to a T-frame 24.

[0038] The two ends of the T-frame 24 are respectively connected to the central shaft of the lower gear 45 by bearings. The symmetrical racks 47 respectively mesh with the corresponding lower gears 45. The central shafts of the symmetrical lower gears 45 are respectively fixedly connected to the upper gears 46. The symmetrical upper gears 46 respectively mesh with the half gear rings 410. The symmetrical half gear rings 410 are respectively fixedly connected to the corresponding mounting arc plates 49.

[0039] The T-frame 24 is fixedly connected to the herringbone block 25, and the transverse groove 41 is fixedly connected to the guide crossbar 43, which passes through the herringbone block 25.

[0040] The auxiliary lever 411 has a set of evenly distributed slots at its end.

[0041] The round head plate 52 is threadedly connected to the adjusting screw 512, and the adjusting screw 512 contacts the ring 55.

[0042] It also includes an installation component 1, which includes an installation L-plate 11. The installation L-plate 11 is fixedly connected to symmetrical hydraulic rods 12, and the piston rods of the symmetrical hydraulic rods 12 are respectively fixedly connected to the base plate 26.

[0043] Example 1: The mounting block 513 is fixedly connected to the L plate 27.

[0044] The workflow of this embodiment is as follows:

[0045] Install the L-plate 11 onto the moving mechanism, which then drives the device to move forward, backward, and turn.

[0046] The hydraulic rod 12 is extended to move the bracket assembly 2, power assembly 4, and actuation assembly 5 downward to the appropriate position.

[0047] The movement of the control mechanism simultaneously controls the rotation of the power motor 44 and the rotary motor 51. The power motor 44 drives the L-axis 42 to move, the circular shaft of the L-axis 42 moves along the transverse groove 41, the L-axis 42 drives the transverse groove 41 to move, the transverse groove 41 drives the guide bar 43 to move along the loop block 25, the transverse groove 41 drives the rack 47 to move, the rack 47 drives the lower gear 45 to rotate, the lower gear 45 drives the upper gear 46 to rotate, the upper gear 46 drives the half gear ring 410 to move, the gear ring 410 drives the mounting arc plate 49 to move along the limiting arc plate 23, the mounting arc plate 49 drives the limiting vertical rod 412, the receiving plate 413 and the auxiliary lever 411 to move.

[0048] The rotary motor 51 drives the guide column 511, spring 510, stepped frustum 57, actuating rod 58 and hemisphere 59 to rotate. The stepped frustum 57 drives the round-head rod 56 to move along the ring 55. The round-head rod 56 drives the stepped frustum 57 to move along the guide column 511. The stepped frustum 57 drives the spring 510 to move. The stepped frustum 57 drives the actuating rod 58 and hemisphere 59 to move.

[0049] Depending on the hardness of the corn, rotating the adjusting screw 512 causes the ring 55 to swing under the elastic action of the spring 510. The ring 55 drives the block 53 to swing, thereby adjusting the forward and backward movement distance of the lever 58. The harder the corn, the smaller the forward and backward movement distance of the lever 58.

[0050] The lever 58 rotates to press down the corn on both sides. A pressure sensor is installed inside the lever 58. When it encounters greater resistance, it reduces its speed or stops. The lever 58 continues to move back and forth to press down the harder corn.

[0051] Use equipment to cut the corn.

[0052] When the auxiliary lever 411 swings forward, it does not move the corn stalk due to the obstruction of the corn stalk. When the auxiliary lever 411 swings backward, it first contacts the corn stalk and does not move. After the limiting vertical rod 412 contacts the auxiliary lever 411, it moves the cut corn to both sides.

[0053] Example 2: The L plate 27 is fixedly connected to the motor base 29, the motor base 29 is fixedly connected to the motor 210, the output shaft of the motor 210 is fixedly connected to the screw 28, the screw 28 is threadedly connected to the mounting block 513, and the mounting block 513 contacts the motor base 29.

[0054] The workflow of this embodiment is as follows:

[0055] When encountering harder corn, the control motor 210 rotates back and forth, driving the screw 28 to rotate back and forth. The screw 28 drives the actuating component 5 to move left and right as a whole, adjusting its position to process the harder corn.

[0056] Example 3: This example is a further elaboration based on Example 1 or 2, and also includes a cutting assembly 3. The cutting assembly 3 includes symmetrical cutting seats 31. The two ends of the transverse groove 41 are respectively fixedly connected to the corresponding cutting seats 31. The symmetrical cutting seats 31 are respectively fixedly connected to symmetrical electric cutting push rods 32. The push rod of each electric cutting push rod 32 is respectively fixedly connected to a chainsaw seat 34. The symmetrical chainsaw seats 34 are respectively fixedly connected to symmetrical chainsaw motors 35. The output shaft of each chainsaw motor 35 is respectively fixedly connected to a saw blade 33.

[0057] The workflow of this embodiment is as follows:

[0058] When the horizontal groove 41 moves, it drives the cutting component 3 to move back and forth.

[0059] Based on the spacing between corn rows, the extension and retraction of the electric cutting push rod 32 is controlled. While the power motor 44 and the rotary motor 51 are rotating, the electric saw motor 35 is controlled to rotate. The electric saw motor 35 drives the saw blade 33 to rotate. The saw blade 33 rotates and moves in the front and back direction, thereby cutting the corn that has been pressed down by the push rod 58.

[0060] This device uses a lever 58 to rotate and press down the corn on both sides. A pressure sensor is installed inside the lever 58; when encountering significant resistance, the speed is reduced or stopped. The lever 58 continues to move back and forth, pressing down harder corn. Depending on the corn's hardness, rotating the adjusting screw 512 causes the ring 55 to swing under the elastic action of the spring 510. The smaller the angle between the ring 55 and the round head plate 52, the smaller the back-and-forth movement distance of the lever 58, thus adjusting the back-and-forth movement distance. The harder the corn, the smaller the back-and-forth movement distance of the lever 58, achieving the goal of pressing down the corn.

[0061] This device features an auxiliary lever 411. When the auxiliary lever 411 swings forward, it does not move the corn stalks due to the obstruction of the corn stalks. When the auxiliary lever 411 swings backward, it first contacts the corn stalks and does not move. After the limiting vertical rod 412 contacts the auxiliary lever 411, it drives the auxiliary lever 411 to move, thus moving the cut corn to both sides for easier subsequent collection.

[0062] The above-disclosed embodiments are merely specific examples of the present invention. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
