Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a multifunctional root and stem combine harvester cutting platform. Background Technology
[0002] Current root and stem harvesters, such as garlic harvesters, generally have a header structure that includes a feeding unit, a shoveling unit, a lifting and conveying unit, and a stem-cutting unit. This means that the garlic shoots and bulbs are first pulled up or dug up together, and then fed into the subsequent shoot removal unit to cut off the shoots. This harvesting method is prone to garlic shoot entanglement problems. During transport, the shoots easily become tangled on the conveyor belt, causing blockages and affecting the normal operation of the harvester. Furthermore, entanglement can lead to excessive wear or damage to components of the conveyor system, increasing maintenance costs. Frequent cleaning of entangled shoots can interrupt harvesting operations, reducing harvesting efficiency. Additionally, the pulling between the shoots and bulbs during digging and transport can damage the bulbs. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model discloses a multi-functional root and stem combine harvester cutting platform, which solves the problem of garlic sprouts getting entangled in existing cutting platforms, as well as the technical problem of garlic bulbs being damaged due to the pulling between garlic sprouts and garlic bulbs.
[0004] This utility model is achieved through the following technical solution:
[0005] A multi-functional root and stem combine harvester cutting platform includes a garlic sprout shredder installed at the front of the frame, a garlic sprout cutting mechanism installed below and at the front of the shredder, a back-and-forth swinging blade mechanism installed on the frame behind the shredder, a conveying and lifting mechanism installed on the frame behind the blade mechanism, and a horizontally arranged drive shaft installed at the rear of the frame. The drive shaft is connected to a power input device installed on the harvester. The cutting mechanism is connected to the drive shaft via a first drive mechanism, the shredder is connected to the drive shaft via a second drive mechanism, and the blade mechanism is connected to the drive shaft via a third drive mechanism.
[0006] Further optimized, a rotary blade mechanism is provided on the frame on both sides of the moving blade mechanism. The rotary blade mechanism includes a vertical rotating shaft that is rotatably mounted on the frame. A rotating blade is provided at the lower part of the vertical rotating shaft. A sleeve is fitted on the vertical rotating shaft above the rotating blade. The vertical rotating shaft is connected to the transmission shaft through a fifth transmission mechanism.
[0007] In a further optimized manner, the movable blade holder of the shearing mechanism is connected to the swing arm of the swing ring box through a first linkage mechanism. The lower end of the first linkage mechanism is hinged to the movable blade holder, and the upper end of the first linkage mechanism is hinged to the swing arm. The input shaft of the swing ring box is connected to the transmission shaft through a first transmission mechanism.
[0008] Further optimized, the moving blade mechanism includes a wide shovel and a central rotating shaft mounted on the frame. The central rotating shaft is connected to the transmission shaft via a third transmission mechanism. An eccentric bearing is provided at each end of the central rotating shaft. A moving blade support is provided on each side of the wide shovel. The middle part of the moving blade support is hinged to the frame, and the upper part of the moving blade support is hinged to the second connecting rod. The other end of the second connecting rod is connected to the outer ring of the eccentric bearing. Several iron pipes are provided at intervals at the end of the wide shovel near the conveying and lifting mechanism. A flexible component is provided at the end of each iron pipe.
[0009] In a further optimized manner, the conveying and lifting mechanism includes two horizontally rotatable shafts mounted on the frame. The two horizontal shafts are connected by a chain, and rake teeth are provided on the chain. One of the horizontal shafts is connected to a hydraulic motor mounted on the frame via a fourth transmission mechanism.
[0010] Further optimized, a lifting hydraulic cylinder for the seedling killer is installed on the frame, and the piston rod of the lifting hydraulic cylinder is hinged to the support of the seedling killer.
[0011] Further optimized, a left and right leveling hydraulic cylinder is respectively installed on the frame on one side of the two rotary cutter mechanisms. The piston rod of the left and right leveling hydraulic cylinder is hinged to the frame, and the bottom of the left and right leveling hydraulic cylinder is hinged to an adjusting plate. The other end of the adjusting plate is hinged to the frame.
[0012] The beneficial effects of this utility model are as follows:
[0013] This invention's cutting platform first cuts off the garlic sprouts using a shearing mechanism, then pulverizes the sprouts using a shredder and drops them into the field. A swaying blade mechanism then scoops the garlic bulbs (without sprouts) from the soil, and as the harvester moves, the bulbs on the blade mechanism reach the conveying and lifting mechanism. Using this cutting platform eliminates the problems of garlic sprouts tangling and damage to the garlic bulbs caused by pulling between the sprouts and bulbs.
[0014] When the cutting platform needs to be adjusted left or right, the rotary cutter mechanism can break the soil left or right, reducing the left and right resistance of the moving cutter mechanism and making the left and right direction adjustment more flexible when moving.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0021] like Figure 1-3 As shown, a multi-functional root and stem combine harvester cutting platform includes a garlic sprout shredder 2 installed at the front of the frame 1, a garlic sprout cutting mechanism installed below and at the front of the shredder 2, a back-and-forth swinging blade mechanism installed on the frame 1 behind the shredder 2, a conveying and lifting mechanism installed on the frame 1 behind the blade mechanism, and a horizontally arranged drive shaft 3 installed at the rear of the frame 1. The drive shaft 3 is connected to a power input device installed on the harvester. The cutting mechanism is connected to the drive shaft 3 through a first drive mechanism, the shredder is connected to the drive shaft 3 through a second drive mechanism, and the blade mechanism is connected to the drive shaft 3 through a third drive mechanism.
[0022] This invention's cutting platform first cuts off the garlic sprouts using a shearing mechanism, then pulverizes the sprouts using a shredder, causing them to fall into the field. A swaying blade mechanism then scoops the garlic bulbs (without sprouts) from the soil. As the harvester moves, the garlic bulbs on the blade mechanism reach a conveying and lifting mechanism, which then elevates them into other functional modules of the harvester, such as the soil-crushing and slag-removing module. Using this cutting platform eliminates the problems of garlic sprouts entanglement and damage to the garlic bulbs due to pulling between the sprouts and bulbs.
[0023] In some embodiments, a rotary blade mechanism is provided on the frame 1 on both sides of the moving blade mechanism. The rotary blade mechanism includes a vertical rotating shaft 4 that is rotatably mounted on the frame 1. A rotating blade 5 is provided at the lower part of the vertical rotating shaft 4. A sleeve 6 is sleeved on the vertical rotating shaft 4 above the rotating blade 5. The vertical rotating shaft 4 is connected to the transmission shaft 3 through a fifth transmission mechanism.
[0024] The sleeve 6 and rotating blade 5 of the rotary blade mechanism rotate inward, making it difficult for garlic cloves to flow out from the sides of the moving blade mechanism. When the cutting platform needs to be adjusted left or right, the rotary blade mechanism can break the soil left or right, reducing the left and right resistance of the moving blade mechanism and making left and right direction adjustments more flexible during movement.
[0025] In some embodiments, the movable blade holder 23 of the shearing mechanism is connected to the rocker arm of the swing ring box 8 via the first linkage mechanism 7, and the input shaft of the swing ring box 8 is connected to the transmission shaft 3 via the first transmission mechanism.
[0026] The shearing mechanism uses blades similar to those used in wheat harvesters, including a movable blade holder and a fixed blade holder. The swing arm of the swing ring box 8 periodically swings, driving the first linkage mechanism 7 to swing, which in turn causes the movable blade holder to reciprocate linearly relative to the fixed blade holder, achieving the opening and closing effect of the shears and completing the cutting of the garlic sprouts. Cutting the garlic sprouts with the shearing mechanism results in a more aesthetically pleasing cut garlic bulb compared to directly crushing the garlic sprouts with a shredder.
[0027] In some embodiments, the moving blade mechanism includes a wide shovel 9 and a central shaft 10 mounted on the frame 1. The central shaft 10 is connected to the transmission shaft 3 via a third transmission mechanism. An eccentric bearing 11 is provided at each end of the central shaft 10. A moving blade support 12 is provided on each side of the wide shovel 9. The middle part of the moving blade support 12 is hinged to the frame 1. The upper part of the moving blade support 12 is hinged to the second connecting rod 13. The other end of the second connecting rod 13 is connected to the outer ring of the eccentric bearing 11. A plurality of iron pipes 14 are provided at intervals at one end of the wide shovel 9 near the conveying and lifting mechanism. A flexible member 15 is provided at the end of each iron pipe 14.
[0028] As the eccentric bearing 11 rotates, it drives the second connecting rod 13 to move radially relative to the central rotating shaft 10. The second connecting rod 13 drives the moving blade support 12 to swing, thereby realizing the back-and-forth swing of the wide shovel 9. As the wide shovel 9 swings back and forth, soil leaks from the gap between the iron pipe 14 and the flexible component 15 onto the ground, leaving only garlic cloves. The rake teeth 18 on the conveying and lifting mechanism cooperate with the flexible component 15 to lift the garlic cloves and send them into the conveying and lifting mechanism. The flexible component 15 is used to avoid damaging the garlic.
[0029] In some embodiments, the conveying and lifting mechanism includes two horizontally rotating shafts 16 that are horizontally and rotatably mounted on the frame 1. The two horizontally rotating shafts 16 are connected by a chain 17. Rake teeth 18 are provided on the chain 17. One of the horizontally rotating shafts 16 is connected to a hydraulic motor 19 mounted on the frame 1 via a fourth transmission mechanism.
[0030] In some embodiments, a seedling-killing machine lifting hydraulic cylinder 20 is provided on the frame 1, and the piston rod of the seedling-killing machine lifting hydraulic cylinder 20 is hinged to the support of the seedling-killing machine. The seedling-killing machine lifting hydraulic cylinder 20 is controlled to adjust the height of the seedling-killing machine 2 relative to the frame 1.
[0031] In some embodiments, a left-right leveling hydraulic cylinder 21 is provided on the frame 1 on one side of the two rotary cutter mechanism. The piston rod of the left-right leveling hydraulic cylinder 21 is hinged to the frame 1, and the bottom of the left-right leveling hydraulic cylinder 21 is hinged to an adjusting plate 22. The other end of the adjusting plate 22 is hinged to the frame 1.
[0032] When the rotating blade 5 and the wide shovel 9 on one side penetrate the soil to a greater depth, the penetration depth can be reduced by controlling the extension of the piston rod of the left and right leveling hydraulic cylinder 21, thus achieving leveling of the left and right sides of the cutting platform.
[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model. For those skilled in the art, any alternative improvements or transformations made to the implementation of this utility model fall within the protection scope of this utility model.
[0034] Any aspects of this utility model not described in detail are known to those skilled in the art.
