Description

Technical Field

[0001] This invention relates to the field of forage harvesting equipment technology, and in particular to a forage harvester. Background Technology

[0002] With the continuous development of hydroponics technology, hydroponically grown forage has become an important means of reducing livestock costs. Furthermore, multi-layered planting in smart forage factories, with its advantages of small footprint, short pasture growth cycle, and low dependence on external climate, has become a significant source of forage for the livestock industry.

[0003] Currently, in smart forage planting factories, forage is harvested either manually or by manually removing the forage trays from multi-layer planting racks and then placing them onto harvesting equipment for automatic harvesting. Regardless of the method, the process of removing the forage trays from the multi-layer planting racks and placing them back on the harvesting racks after harvesting is necessary. For large-scale smart forage planting factories, traditional forage harvesting methods still suffer from low harvesting efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a forage harvester that can be applied to intelligent forage planting workshops and can significantly improve forage harvesting efficiency.

[0005] A forage harvester, comprising:

[0006] Walking mechanism;

[0007] The fuselage is mounted on the walking mechanism;

[0008] The lifting platform is slidably mounted on the machine body;

[0009] A lifting drive mechanism is connected to the lifting platform and is used to drive the lifting platform to rise or fall.

[0010] A harvesting mechanism includes a harvesting platform, a rotary drive, and a harvesting conveying structure. One end of the harvesting platform is rotatably mounted on a lifting platform. The harvesting conveying structure is mounted on the harvesting platform. The rotary drive is connected to the harvesting platform and drives the harvesting platform to rotate laterally around the connecting shaft between the harvesting platform and the lifting platform, thereby switching the working state of the harvesting mechanism to a harvesting state in which the harvesting platform is extended outward to the side of the machine body and an unharvested state in which the harvesting platform is retracted inward to the front of the machine body.

[0011] The receiving bin is installed on the machine body and located below the lifting platform;

[0012] The harvesting and conveying structure is configured to harvest the forage on the multi-layer planting racks in the smart forage workshop and convey the harvested forage to the receiving bin during the harvesting state.

[0013] The aforementioned forage harvester, when needing to harvest forage on multi-layered planting racks within a smart forage planting factory, utilizes a lifting drive mechanism to raise or lower the harvesting platform, adjusting it to a position equal to or slightly higher than the layer to be harvested on the multi-layered planting racks. Then, a rotary drive switches the harvesting mechanism to harvesting mode. Following this, a traveling mechanism propels the entire forage harvester through the aisles between the multi-layered planting racks. Simultaneously, the harvesting platform extends above the layer to be harvested, and the harvesting and conveying structure harvests and collects the forage on that layer. Therefore, this forage harvester can automatically harvest all forage on multi-layered planting racks within a smart forage planting factory, eliminating the need for manual removal of forage trays from the racks for harvesting and subsequent return of the harvested trays. This significantly improves the harvesting speed within the smart forage planting factory while saving substantial labor costs. Therefore, the use of the aforementioned forage harvesters has greatly improved the forage harvesting efficiency in smart forage planting factories and reduced forage harvesting costs.

[0027] Please see Figure 1 and Figure 2 The forage harvester 10 in the preferred embodiment of the present invention is used for forage harvesting operations in a smart forage planting factory. The forage harvester 10 includes a walking mechanism 100, a machine body 200, a lifting platform 300, a lifting drive mechanism 400, a harvesting mechanism 500, and a receiving bin 600.

[0028] The machine body 200 is mounted on the walking mechanism 100. The walking mechanism 100 is used to drive the machine body 200 to move on the ground, that is, the walking mechanism 100 can drive the whole machine to move on the ground.

[0029] The lifting platform 300 is slidably mounted on the machine body 200.

[0030] The lifting drive mechanism 400 is connected to the lifting platform 300 and is used to drive the lifting platform 300 to rise or fall.

[0031] Please refer to the following: Figures 3 to 5 The harvesting mechanism 500 includes a harvesting platform 510, a rotary drive 520, and a harvesting conveying structure 530. One end of the harvesting platform 510 is rotatably mounted on the lifting platform 300. The harvesting conveying structure 530 is mounted on the harvesting platform 510. The rotary drive 520 is connected to the harvesting platform 510 and is used to drive the harvesting platform 510 to rotate laterally around the connecting shaft between the harvesting platform 510 and the lifting platform 300, so as to switch the working state of the harvesting mechanism 500 to a harvesting state in which the harvesting platform 510 is spread outward to the side of the machine body 200, and an unharvested state in which the harvesting platform 510 is retracted inward to the front of the machine body 200.

[0032] The receiving bin 600 is installed on the machine body 200 and located below the lifting platform 300. Specifically, the receiving bin 600 is located below the harvesting platform 510 near the end of the machine body 200.

[0033] The harvesting and conveying structure 530 is configured to harvest the forage on the multi-layer planting racks in the smart forage workshop and convey the harvested forage to the receiving bin 600 in the harvesting state. Therefore, the harvesting and conveying structure 530 has the function of cutting the forage and conveying the cut forage to the receiving bin 600.

[0034] To facilitate understanding, the following is a brief explanation of the process of harvesting forage using the aforementioned forage harvester 10:

[0035] The unharvested hay harvester 10 is parked at one end of the aisle inside the smart hay planting factory.

[0036] The lifting drive mechanism 400 drives the lifting platform 300 to raise or lower the harvesting mechanism 500 until the position height of the harvesting platform 510 is the same as or slightly higher than the height of the layer to be harvested on the multi-layer harvesting rack.

[0037] The harvesting platform 510 is driven by the rotary drive component 520 to rotate the harvesting conveyor structure 530 until the working state of the harvesting mechanism 500 is switched to the harvesting state.

[0038] The walking mechanism 100 moves at a preset speed in the aisle between the multi-layer planting racks. At this time, the harvesting platform 510 extends onto the harvesting layer of the multi-layer planting rack. As the forage harvester 10 moves forward, the harvesting and conveying structure 530 cuts the forage on the harvesting layer and conveys the cut forage to the collection bin 600 for collection.

[0039] Thus, through the lifting drive mechanism 400 and the lifting platform 300, the forage harvester 10 can harvest the forage on each layer of the multi-layer planting rack in the smart forage planting factory. Through the cooperation of the harvesting mechanism 500 and the walking mechanism 100, the forage on the multi-layer planting rack can be harvested automatically and quickly. Therefore, by using the forage harvester 10 to automatically harvest the forage on the multi-layer planting rack in the smart forage planting factory, the process of manually removing the forage trays from the multi-layer planting rack for harvesting and putting the harvested forage trays back into the multi-layer planting rack is eliminated, which greatly improves the harvesting speed of forage in the smart forage planting factory and saves a lot of labor costs.

[0040] When forage harvesting is not required, the harvesting platform 510 can be rotated using the rotary drive mechanism until it retracts inward to the front of the machine body 200. This switches the working state of the forage harvester 10 to the unharvested state, preventing the harvesting mechanism 500 from colliding with objects nearby during the operation of the forage harvester 10, thus improving the convenience and safety of using the forage harvester 10.

[0041] Therefore, the use of the aforementioned forage harvester 10 greatly reduces the forage harvesting efficiency in the smart forage planting factory and lowers the forage planting cost.

[0042] Please refer to it again. Figure 5In some embodiments, the harvesting platform 510 has a harvesting area 511 at the end away from the machine body 200 and a guiding area 512 at the end closer to the machine body 200. Multiple grass-supporting troughs 513 are spaced apart along the longitudinal direction of the harvesting platform 510 in the harvesting area 511. When the harvesting mechanism 500 is in the harvesting state, each grass-supporting trough 513 is located at the front edge of the harvesting platform 510 in the traveling direction of the traveling mechanism 100. The grass-supporting trough 513 can be a through groove in the shape of a rectangular groove, a V-shaped groove, a U-shaped groove, a toothed groove, etc.

[0043] The harvesting and conveying structure 530 includes a support 531, a cutter 532, a pusher plate 533, and a harvesting drive component 534. The support 531 is mounted on the harvesting platform 510. The cutter 532 and the pusher plate 533 are both mounted on the support 531.

[0044] The harvesting drive unit 534 is connected to the cutter 532 and the pusher plate 533 respectively, and is used to drive the cutter 532 and the pusher plate 533 to rotate around the bracket 531 on the harvesting platform 510, so that the cutter 532 cuts the grass in the grass-feeding trough 513 and the pusher plate 533 pushes the cut grass through the guide area 512 into the receiving bin 600.

[0045] It should be noted that the longitudinal direction of the harvesting platform 510 refers to the direction that is perpendicular or nearly perpendicular to the walking direction of the walking mechanism 100 in the harvesting state, and the direction that is consistent with or nearly consistent with the walking direction of the walking mechanism 100 in the unharvested state.

[0046] The forage on the multi-layer planting rack is arranged in rows and columns or in a matrix of cave planting. When harvesting forage using the forage harvester 10, each grass support trough 513 must first be aligned with a row of forage. As the walking mechanism 100 drives the entire forage harvester 10 forward, the forage first enters the corresponding grass support trough 513. At the same time, the harvesting drive 534 drives the cutter 532 and the pusher plate 533 to rotate around the support 531. During the rotation of the cutter 532, the forage in the grass support trough 513 is cut. The pusher plate 533, located behind the cutter 532, immediately pushes the cut forage forward during the rotation until it falls into the collection bin 600 after passing through the guide area 512.

[0047] Therefore, the grass-supporting trough 513 can support the entire grass near the root, ensuring that the cutter 532 can effectively cut the grass when passing through the grass-supporting trough 513. The pusher plate 533 moves synchronously with the cutter 532, ensuring that the cut grass can be pushed into the collection bin 600 in a timely and smooth manner. This reduces the probability of grass not being cut or the cut grass not being pushed in time during the grass harvesting process, and greatly improves the grass harvesting effect.

[0048] Furthermore, in some embodiments, the harvesting area 511 is a double-layered structure with a blade passage space (not shown). The grass-supporting trough 513 is connected to the blade passage space. The harvesting drive unit 534 is used to drive the cutter 532 to enter the blade passage space and then cross the grass-supporting trough 513, and is also used to drive the pusher plate 533 to pass over the harvesting area 511.

[0049] During the forage harvesting process, the forage located in the forage support trough 513 is supported by the double-layer structure at both the top and bottom. Then, when the cutter 532 passes through the forage support trough 513 from the cutting space, the cutter 532 will cut the forage between the two support points. This makes the cutter 532 more effective in cutting the forage, and the forage is easier to cut, further improving the forage harvesting effect.

[0050] Furthermore, in some embodiments, there are multiple cutters 532 and pusher plates 533, each corresponding to a specific cutter 532. The multiple cutters 532 are arranged sequentially at intervals along their rotation direction. In the rotation direction of the cutter 532, the pusher plates 533 are spaced behind the corresponding cutter 532.

[0051] That is, in the multiple cutters 532 and multiple pusher plates 533, each cutter 532 and its corresponding pusher plate 533 are grouped together to cooperate in cutting and conveying the forage. Setting multiple groups of cutters 532 and pusher plates 533 can increase the frequency of cutting and pushing. Therefore, when harvesting forage on multi-layer planting racks, even if the walking mechanism 100 drives the entire forage harvester 10 forward at a relatively fast speed, the multiple groups of cutters 532 and pusher plates 533 rotating around the support 531 in sequence can still completely harvest the forage on the multi-layer planting racks. Therefore, setting multiple cutters 532 and pusher plates 533 in a one-to-one correspondence can further improve the forage harvesting efficiency and help to further reduce the cost of forage planting.

[0052] Furthermore, in some embodiments, the guiding area 512 is provided with a first baffle plate 540. The first baffle plate 540 and the grass-supporting trough 513 are located on the same side of the harvesting platform 510. One end of the first baffle plate 540 extends to the edge of the harvesting platform 510 away from the harvesting area 511, and the other end extends to a position near the harvesting area 511. A second baffle plate 550 is also provided on the side of the bracket 531 near the grass-supporting trough 513. One end of the second baffle plate 550 extends to the harvesting area 511, and the other end extends to the guiding area 512. The first baffle plate 540 and the second baffle plate 550 are spaced apart.

[0053] The setting of the first baffle plate 540 and the second baffle plate 550 can reduce the probability that the forage will fall off the two sides of the harvesting platform 510 during the process of the pusher plate 533 pushing the cut forage in the harvesting area 511 to the harvesting bin 600, thereby reducing waste in the forage harvesting process.

[0054] The first baffle plate 540 can be a flat plate, a bent plate with one end bent outward near the harvesting area 511, or a plate structure of other shapes such as arc. The second baffle plate 550 can be a smooth plate or a perforated plate, as long as it can block the grass during the pushing process.

[0055] Furthermore, in some embodiments, a third baffle plate 560 is provided at the end of the harvesting area 511 away from the material guiding area 512. Specifically, the baffle plate is arranged perpendicularly to or intersecting with the spacing direction of the plurality of grass-supporting troughs 513.

[0056] Thus, the third baffle 560 can prevent cut hay from falling out of the harvesting platform 510 away from the machine body 200 during the hay harvesting process, reducing waste during the hay harvesting process.

[0057] Please refer to it again. Figure 5 In some embodiments, the harvesting and conveying structure 530 further includes two chain drive assemblies 535. Each chain drive assembly 535 includes a first sprocket 5351, a second sprocket 5352, and a chain 5353. The chain 5353 is tensioned between the first sprocket 5351 and the second sprocket 5352.

[0058] Two first sprockets 5351 are spaced apart at one end of the bracket 531 along a direction perpendicular to the harvesting platform 510, and are both drively connected to the output shaft of the harvesting drive unit 534. Two second sprockets 5352 are spaced apart and coaxially arranged along a direction perpendicular to the harvesting platform 510, and are rotatably mounted on the other end of the bracket 531. One end of the cutter 532 is connected to two chains 5353 respectively. One end of the pusher plate 533 is connected to two chains 5353 respectively.

[0059] Thus, power is transmitted between the harvesting drive unit 534 and the cutter 532, and between the harvesting drive unit 534 and the pusher plate 533, through two chain drive assemblies 535. The two chain drive assemblies 535 are arranged vertically at intervals, so that both the cutter 532 and the pusher plate 533 have two force points. This ensures that the cutter 532 and the pusher plate 533 operate stably during the forage harvesting operation, and that the force applied when the cutter 532 cuts the forage and the pusher plate 533 pushes the forage is more effective, thereby improving the forage harvesting effect.

[0060] Please refer to it again. Figure 1In some embodiments, there are two harvesting mechanisms 500. Two harvesting platforms 510 are rotatably mounted at the left and right ends of the lifting platform 300, respectively. When the harvesting mechanism 500 is in the harvesting state, one harvesting platform 510 extends outward to the side of the machine body 200, or both harvesting platforms 510 extend to the left and right sides of the machine body 200, respectively. When the harvesting mechanism 500 is in the unharvested state, both harvesting platforms 510 are located in front of the machine body 200 and are spaced apart along the left-right direction of the machine body 200.

[0061] In actual use, if it is necessary to harvest the forage on the multi-layer planting rack on one side of the aisle, simply open the harvesting conveyor structure 530 on the side closest to the multi-layer planting rack. If it is necessary to harvest the forage on the multi-layer planting rack on both sides of the aisle at the same time, both harvesting conveyor structures 530 need to be opened outward to the left and right sides of the machine body 200 to facilitate the simultaneous harvesting of the forage on the multi-layer planting rack on both sides of the aisle. In other words, the forage harvester 10 can harvest the forage on two multi-layer planting racks at the same time, further improving the harvesting efficiency of forage in the smart planting workshop.

[0062] Please refer to the following: Figure 6 In some embodiments, the receiving hopper 600 includes a base plate 610, side plates 620 arranged circumferentially along and connected to the base plate 610, a front door 630, and a door drive 640. The base plate 610 and the side plates 620 form a hollow structure with an open top. The base plate 610 is inclined downward relative to the harvesting platform 510 along the machine body 200 from rear to front. A discharge port (not shown) is formed on the side of the side plate 620 opposite to the machine body 200. One end of the front door 630 is rotatably connected to the edge of the discharge port. The door drive 640 is drively connected to the front door 630 and is used to drive the front door 630 to rotate, thereby opening or closing the discharge port.

[0063] Using the travel direction of the forage harvester 10 as a reference direction, the discharge port is located in front of the receiving bin 600, and the bottom plate 610 is also inclined downwards in a rear-to-forward direction. Therefore, when it is necessary to clean out the forage in the receiving bin 600, the front door 630 is automatically opened by using the door drive component 640. At this time, the forage in the receiving bin 600 will slide out of the discharge port along the inclined direction of the bottom plate 610 under its own gravity, realizing the automatic discharge and cleaning of the forage in the receiving bin 600. This is conducive to further improving the forage harvesting efficiency and makes the forage harvester 10 more convenient to use.

[0064] Please refer to the following: Figure 7In some embodiments, the forage harvester 10 also includes a counterweight 700. The counterweight 700 is slidably mounted on the body 200. The counterweight 700 is linked to the lifting platform 300 and is configured to descend when the lifting platform 300 rises and rise when the lifting platform 300 descends. The linkage between the counterweight 700 and the lifting platform 300 can be achieved through a transmission component or a mechanical structure; that is, under the driving force provided by the lifting drive mechanism 400, the counterweight 700 and the lifting platform 300 can move in an alternating manner.

[0065] In actual use, when the lifting platform 300 raises the harvesting mechanism 500 to the height of the machine body 200, the counterweight 700 lowers to the lower part of the machine body 200 to avoid a top-heavy situation during hay harvesting and ensure the stability of the hay harvester 10 during harvesting operations. Similarly, when the lifting platform 300 lowers the harvesting mechanism 500 to the lower part of the machine body 200, the counterweight 700 will correspondingly rise to the higher part of the machine body 200 to ensure that the entire hay harvester 10 is vertically balanced. Therefore, the setting of the counterweight 700 can improve the overall stability of the hay harvester 10 during hay harvesting operations and travel, reduce the probability of tipping over, and ensure high safety during use.

[0066] Furthermore, in some embodiments, the forage harvester 10 also includes a drive shaft 810, a first drive wheel 820, a second drive wheel 830, a third drive wheel 840, a first drive bar 850, a second drive bar 860, a fourth drive wheel 870, and a third drive bar 880.

[0067] A drive shaft 810 is rotatably mounted on the top of the machine body 200. Specifically, the drive shaft 810 is horizontally arranged on the machine body 200. A first drive wheel 820 is sleeved on and drivenly connected to the output shaft of the lifting drive mechanism 400. Second drive wheels 830 are spaced apart and sleeved on the drive shaft 810, and are drivenly connected to the drive shaft 810. A first drive bar 850 is tensioned on the first drive wheel 820 and the second drive wheel 830. A second drive bar 860 is tensioned on the third drive wheel 840, with one end connected to the counterweight 700 and the other end connected to the bottom end of the machine body 200.

[0068] The fourth drive wheel 870 is rotatably mounted on the top of the machine body 200. The third drive bar 880 is tensioned on the fourth drive wheel 870, with one end connected to the counterweight 700 and the other end connected to the lifting platform 300.

[0069] Among them, the first transmission wheel 820, the second transmission wheel 830, and the third transmission wheel 840 can be pulleys or sprockets, and the first transmission bar 850 and the second transmission bar 860 can be transmission belts or transmission chains; the fourth transmission wheel 870 can be a pulley, sprocket, pulley, etc., and the third transmission bar 880 can also be a transmission belt, transmission chain, wire rope, etc.

[0070] In actual use, the rotating shaft of the lifting drive mechanism 400 transmits power to the transmission shaft 810 through the first transmission wheel 820, the first transmission bar 850, and the second transmission wheel 830, causing the transmission shaft 810 to rotate. The rotation of the transmission shaft 810 drives the third transmission wheel 840 to rotate. The rotation of the third transmission wheel 840 can drive the second transmission bar 860 to move up and down, thereby causing the counterweight 700 to rise or fall. The rise or fall of the counterweight 700 will pull the lifting platform 300 down or up through the third transmission bar 880. At this time, the counterweight 700 and the lifting platform 300 rise and fall in turn, realizing effective linkage between the counterweight 700 and the lifting platform 300.

[0071] Specifically, in order to ensure the stability of the lifting of the counterweight 700 and the lifting platform 300, there are two sets of the second transmission bar 860 and the third transmission wheel 840, located on the left and right sides of the first transmission bar 850 respectively; there are also two sets of the third transmission bar 880 and the fourth transmission wheel 870, located on the left and right sides of the first transmission bar 850 respectively.

[0072] In some embodiments, a plurality of roller assemblies 900 are provided at the bottom of the body 200. Each roller assembly 900 includes a telescopic frame 910 and movable wheels 920 mounted on the telescopic frame 910. One end of the telescopic frame 910 away from the movable wheels 920 is fixed to the bottom of the body 200. The telescopic frame 910 is configured to drive the movable wheels 920 to extend and retract along the lifting direction of the lifting platform 300.

[0073] The telescopic frame 910 can be a threaded adjustment structure formed by the cooperation of a screw and a nut (for example), or a cylinder telescopic structure, or other telescopic structures that can drive the moving wheel 920 to rise or fall.

[0074] After prolonged use, the walking mechanism 100 will inevitably encounter various problems, requiring maintenance, repair, or replacement. In this case, the telescopic frame 910 needs to be extended until the moving wheels 920 contact the ground and support the machine body 200. Then, the walking mechanism 100 can be detached from the machine body 200 and moved from under the machine body 200 for maintenance or replacement. Therefore, the entire disassembly and assembly process of the walking mechanism 100 does not require additional tools or equipment for lifting or lowering the machine body 200, resulting in low maintenance costs and high convenience. When it is necessary to reassemble the walking mechanism 100, simply move it to the bottom of the machine body 200 and connect it to the machine body 200.

[0075] During normal use of the forage harvester 10, the telescopic frame 910 is shortened until the moving wheels 920 leave the ground, so that the moving wheels 920 can be retracted. At this time, the movement of the forage harvester 10 relies entirely on the walking mechanism 100.

[0076] Therefore, the aforementioned roller assembly 900 makes the maintenance and repair of the forage harvester 10 more convenient, further improving the ease of use of the forage harvester 10.

[0077] Please refer to it again. Figure 3 In some embodiments, the fuselage 200 includes a base 210 and a telescopic gantry 220. A traveling mechanism 100 is mounted on the bottom of the base 210. A lifting platform 300 is mounted on the telescopic gantry 220. The telescopic gantry 220 is configured to raise or lower the lifting platform 300.

[0078] In practical use, depending on the number of layers and height requirements of the multi-layer planting rack, the telescopic characteristics of the telescopic gantry and the lifting characteristics of the lifting platform 300 relative to the telescopic gantry 220 can be utilized to enable the lifting platform 300 to drive the harvesting mechanism 500 to perform one-stage lifting, two-stage lifting, or even multi-stage lifting. This increases the working height of the forage harvester 10 without increasing the overall height of the harvester, thereby improving the applicability of the harvester 10.

[0079] Furthermore, in some embodiments, a foldable receiving net bag 1001 is installed below the lifting platform 300. One end of the receiving net bag 1001 is open towards the end of the harvesting platform 510 that has a guiding area 512, for receiving the hay that slides out from the guiding area 512. The other end of the receiving net bag 1001 is connected to the feed inlet of the receiving bin 600.

[0080] Thus, with the collection net bag 1001 in place, even when the lifting platform 300 raises the harvesting mechanism 500 to its highest position on the machine body 200, the forage pushed from the guide area 512 by the pusher plate 533 can directly enter the collection net bag 1001 during the forage harvesting operation, and then pass through the collection net bag 1001 into the collection bin 600 for collection. Therefore, the collection net bag 1001 can prevent forage from falling from the harvesting platform 510 into the collection bin 600 and spilling onto the ground around the multi-layer planting rack due to the harvesting platform 510 being too high, further reducing forage waste during the forage harvesting operation.

[0081] 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.

[0082] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but 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.
