Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a combined harvesting device used for strip-shaped composite cultivation of fresh corn and fodder beans. Background Art

[0002] Existing forage bean and corn harvesting technologies mainly use separate mechanical equipment for harvesting. In the strip composite cultivation model of forage beans and corn, special forage bean harvesters and corn harvesters are usually required to harvest the two crops separately. These machines are usually independent and each performs specific harvesting tasks, such as cutting, threshing, cleaning and collecting forage beans, and picking, peeling and collecting corn. In actual operation, these machines need to operate successively on the same piece of land to complete the harvesting process of forage beans and corn. This existing technology is widely used in large-scale agricultural production, especially in areas where forage beans and corn are mixed.

[0003] Although the existing forage bean and corn harvesting technologies have basically met market demand in many aspects, there are still some problems with the harvesting methods in strip cultivation. Since multiple machines need to be used in sequence, the use cost and operation complexity are increased. Multiple mechanical operations may also cause compaction of the land, affecting soil health and subsequent planting. The machine size and working mode of the existing technology limit the distance between adjacent harvesters, which may interfere with each other and even cause problems such as grain lodging. Since the harvesting methods and processes of forage beans and corn are different, it is difficult for the existing technology to achieve synchronous harvesting of the two, which reduces the harvesting efficiency and increases the harvesting cost. There is still room for optimization in the utilization of straw and environmental protection treatment. Therefore, these problems restrict the promotion and application of the strip composite planting model of forage beans and corn, and limit the potential of this advanced planting model in modern agriculture. Summary of the Invention

[0004] The embodiment of the present application provides a combined harvesting device for strip-shaped composite cultivation of fresh corn and fodder beans, the main purpose of which is to solve the problems of multiple mechanical operations, high costs, land compaction, interference between adjacent machines, and inability to achieve synchronous harvesting of crops.

DETAILED DESCRIPTION

[0033] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0034] See also Figures 1 to 12As shown, an embodiment of the present application provides a combined harvesting device for strip-shaped composite cultivation of fresh corn and fodder beans, comprising a fresh corn cob harvesting mechanism 2, a mixed harvesting mechanism 1 and a mobile device 7, wherein the fresh corn cob harvesting mechanism 2 and the mixed harvesting mechanism 1 are stacked in an up-and-down direction, wherein the fresh corn cob harvesting mechanism 2 is located above the mixed harvesting mechanism 1 and in front of the mixed harvesting mechanism 1, and the mixed harvesting mechanism 1 is used to harvest corn stalks and the entire fodder bean crop; the mobile device 7 is connected to the rear side of the moving direction of the mixed harvesting mechanism 1 and the fresh corn cob harvesting mechanism 2, and the mobile device 7 is used to provide moving power to the mixed harvesting mechanism 1 and the fresh corn cob harvesting mechanism 2.

[0035] In which, the mixed harvesting mechanism 1 includes a first conveying bin 11 and a second conveying bin 12; the number of the first conveying bins 11 is two, and they are respectively located at the two ends of the rear side of the forward direction of the mixed harvesting mechanism 1; the second conveying bin 12 is arranged between the two first conveying bins 11, and a mixed harvesting frame 14 is fixedly connected to one end of the forward direction of the first conveying bin 11 and the second conveying bin 12, and a mixed conveying roller 19 is arranged in the mixed harvesting frame 14.

[0036] In this example, it should be noted that the combined harvesting equipment is designed for the strip composite cultivation mode of fresh corn and fodder beans, realizing the synchronous harvesting of the two crops. First, the mixed harvesting mechanism 1 and the fresh corn cob harvesting mechanism 2 are arranged in layers, wherein the fresh corn cob harvesting mechanism 2 is located above and in front of the mixed harvesting mechanism 1. This arrangement ensures that within the same moving stroke, the fresh corn cobs and the prepared feed (corn stalks and the whole crop of fodder beans, which may include immature fodder beans) can be effectively processed. When the equipment moves forward, the corn is first harvested by the fresh corn cob harvesting mechanism 2, and then the whole crop of fodder beans and the corn stalks are harvested by the mixed harvesting mechanism 1 below. Through this design, not only the problems of multiple mechanical operations, high costs, and land compaction in the traditional planting model are solved, but also the interference of adjacent machines is avoided, and the synchronous harvesting of fresh corn and fodder beans is realized, which greatly improves the efficiency and promotion potential of the planting model.

[0037] The arrangement of multiple conveying bins (the first conveying bin 11 and the second conveying bin 12) can effectively reduce the obstruction of various crops during the crushing and conveying process, making the crushing process of corn stalks and feed beans of this device smoother and easier. In addition, the multiple conveying bins also provide multiple processing modes, so that each conveying bin has the effect of independent control of opening, which can be opened / closed individually or all at once, which is suitable for more complex harvesting modes.

[0038] See also Figure 1As shown, in another example, the harvested corn cobs can be optionally further processed by the corn cob processing mechanism 4, such as removing leaves and impurities, while the fodder beans are threshed by the fodder bean threshing mechanism 3. The two processing mechanisms are connected to their respective harvesting mechanisms to ensure the continuity of the processing flow. The processed fresh corn and fodder beans are both transported to the fruit collecting mechanism 6 for centralized collection and storage. In order to ensure the efficient operation of the entire equipment, the power mechanism 5 is arranged outside the machine to provide the required power for the fodder bean threshing mechanism 3 and the corn cob processing mechanism 4. The mobile device 7 is located on the rear side of the harvesting mechanism and is equipped with a cab 8 to ensure that the operator can easily control the movement and operation of the entire equipment.

[0039] See also Figures 1 to 11 As shown, in some examples, further, the mixed harvesting mechanism 1 further includes: a feed crushing mechanism 13, a power drive assembly 15, a reel assembly 16, a separation guide assembly 17 and a cutting assembly 18, the feed crushing mechanism 13 is fixedly arranged at the bottom of the two first conveying bins 11 and the second conveying bin 12, and is used to crush corn stalks and feed beans as a whole crop (with independent crushing and all mixed crushing functions for a certain crop); the reel assembly 16 is arranged above the front end of the mixed harvesting frame 14; the separation guide assembly The separating guide assembly 17 is arranged on the reel assembly 16 above the mixed harvesting frame 14, and the bottom end of the separating guide assembly 17 contacts the inner bottom end wall of the mixed harvesting frame 14; the separating guide assembly 17 is adjustably arranged between the fresh corn and the feed beans; the cutting assembly 18 is arranged at the end on the forward direction side of the mixed harvesting frame 14; the power drive assembly 15 is arranged on the mixed harvesting frame 14, and is used to provide operating power to the reel assembly 16, the cutting assembly 18 and the mixed conveying roller 19.

[0040] In this example, it can be understood that the design of the mixed harvesting mechanism 1 takes into account the composite cultivation mode of corn and fodder beans. When the device moves forward, the reel assembly 16 is located at the front and is responsible for guiding the fodder bean plants into the mixed harvesting frame 14. Then, the cutting assembly 18 works at one end of the mixed harvesting frame 14 in the forward direction to efficiently cut the fodder bean crops. If the current crushing process is a mixing function, in order to ensure the correct separation between fresh corn and fodder beans, the separation guide assembly 17 is arranged between the corn and fodder bean planting positions, and its bottom end contacts the inner bottom end wall of the mixed harvesting frame 14 to ensure independent harvesting of the two crops. The two first conveying bins 11 are located at both ends of the forward direction of the mechanism. They work together with the second conveying bin 12 in the middle to achieve crop crushing. Classified harvesting and transportation (such as corn on both sides and fodder beans in the middle, or fodder beans on both sides and corn in the middle are applicable). In order to process the corn stalks after the ears are harvested, the feed crushing mechanism 13 is placed at the bottom of the conveying bin, which is responsible for crushing the corn stalks and / or fodder bean crops. The entire harvesting process is powered by the power drive component 15 to ensure the efficient operation of the reel component 16, the cutting component 18 and the mixing conveying roller 19. Therefore, this device takes into account the composite cultivation of fodder beans and corn, so that the two crops can be processed in the same mechanical operation to obtain corn ears and / or fodder beans. Crushed feed, especially considering the problem that the crop layout of agricultural machinery equipment changes after harvesting in a straight line and turning around, which is not suitable for current agricultural machinery, so this device improves operating efficiency and reduces operating costs.

[0041] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7 As shown, in some examples, further, the mixing conveying roller 19 is arranged on the inner side of the mixing harvesting frame 14, and the mixing harvesting frame 14 is provided with three conveying ports respectively connected to the first conveying bin 11 and the second conveying bin 12, and the mixing conveying roller 19 corresponding to the position of the conveying ports has multiple shift rods in an staggered state and perpendicular to the outer wall of the mixing conveying roller 19.

[0042] It can be understood that the mixing conveying roller 19 is located on the inner side of the mixing harvesting frame 14, corresponding to the three conveying ports, which are respectively connected to the first conveying bin 11 and the second conveying bin 12. During the harvesting process of fodder beans and corn, they are cut by the cutting assembly 18, and through the coordinated work of the first conveying bin 11 and the second conveying bin 12, the corn stalks and the unprocessed fodder bean stalks are respectively conveyed. The multiple staggered levers on the mixing conveying roller 19 are perpendicular to the outer wall of the dragon, which play the role of guiding and pushing the fodder beans and corn stalks. In this example, the spiral structure of the traditional mixing conveying roller 19 is changed, the harvesting process of fodder beans and corn is optimized, and by combining with the aforementioned mechanism parts, a complete and efficient fodder bean harvesting system is formed, which effectively solves the harvesting problem of the composite cultivation mode with corn.

[0043] See also Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 As shown, in some examples, further, the partition guide assembly 17 includes: a supporting beam 171, an adjusting portion 172, a connecting frame 173, a guide plate 174 and a positioning notch 175; the supporting beam 171 is arranged on the reel assembly 16 along the length direction of the mixed harvesting frame 14, and a plurality of positioning notches 175 are provided on the outer wall of the supporting beam 171; the two adjusting portions 172 are movably mounted on the outer wall of the supporting beam 171; the connecting frame 173 is T-shaped and fixedly connected to the bottom end of the adjusting portion 172, and the two guide plates 174 are arc-shaped and are connected in an inclined state at both ends of the forward direction of the connecting frame 173, and the spacing between one end of the two guide plates 174 in the forward direction is smaller than the spacing between the other ends.

[0044] As will be appreciated, the separation and guide assembly 17 is designed to ensure that forage beans and corn are effectively separated and directed to their respective processing areas during the harvesting process. First, a support beam 171 is positioned on the reel assembly 16, extending along the length of the mixed harvesting frame 14. Multiple positioning notches 175 on the outer wall of this beam provide adjustable positions for the adjustment portion 172, allowing the entire guide assembly to be fine-tuned to suit the crop planting range and spacing. The adjustment portion 172 movably fits over the outer wall of the support beam 171, providing a secure base for the connecting frame 173. The T-shaped design of the connecting frame 173 allows it to be securely connected to the bottom end of the adjustment portion 172 and provides support for two guide plates 174. The curved guide plates 174 are tilted and connected to either end of the connecting frame 173 in its forward direction, separating and guiding the crops. When the forage beans and corn enter the harvesting mechanism, these guide plates 174 effectively separate the bean stalks from the harvested corn stalks. Bean straw is directed to one area for further separation, while corn straw is directed to another area for comminution. This design of the separation and guide assembly 17 ensures that bean and corn are not mixed during the harvest process, thereby achieving efficient processing of both crops. This not only improves harvesting efficiency and ensures crop quality, but also reduces the processing difficulty and cost caused by mixing.

[0045] See also Figure 5 、 Figure 6 and Figure 8 As shown, in some examples, further, the adjustment part 172 includes: an adjustment seat 1721, a block 1722 and a handle 1723. The two adjustment seats 1721 can be slidably mounted on the support beam 171, and the adjustment seat 1721 is in a cavity state; the block 1722 can be moved along the opening direction of the positioning notch 175 and is set in the inner cavity of the adjustment seat 1721. The handle 1723 can be rotatably connected to the block 1722 for driving the block 1722 to enter or exit the positioning notch 175. The handle 1723 is screwed to the adjustment seat 1721.

[0046] In this example, it can be understood that the adjustment portion 172 is intended to ensure that the separation guide assembly 17 can be fine-tuned according to the range and spacing of different crops, thereby achieving efficient separation and guidance of feed beans and corn. The adjustment seat 1721 is a slidable cavity structure, which is mounted on the support beam 171 and provides a moving space for the block 1722. The block 1722 is located in the inner cavity of the adjustment seat 1721 and can move along the direction of the positioning notch 175, thereby achieving position adjustment of the separation guide assembly 17. The handle 1723 is connected to the block 1722 and is screwed to the adjustment seat 1721. When the handle 1723 is rotated, the block 1722 can be driven to enter or exit the positioning notch 175, thereby locking or unlocking the position of the adjustment portion 172.

[0047] See also Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 11 As shown, in some examples, further, the feed crushing mechanism 13 includes: a crushing bin 131, a crushing assembly 132, a discharge port 133 and a switching assembly 134, the crushing bin 131 is fixedly built into the second conveying bin 12 and the bottom end of the two first conveying bins 11, and is communicated with the second conveying bin 12 and the two first conveying bins 11; the crushing assembly 132 is arranged in the inner cavity of the crushing bin 131, for crushing the incoming corn stalks; a plurality of discharge ports 133 are opened at the bottom end of the inner cavity of the crushing bin 131, for discharging the crushed straw; the switching assembly 134 is arranged on the crushing bin 131, for switching the connection state between the crushing bin 131 and the first conveying bin 11 and the second conveying bin 12.

[0048] In this example, it is worth mentioning that the feed crushing mechanism 13 is designed to efficiently process the harvested corn stalks, ensuring that they are crushed and discharged evenly. The crushing bin 131 is located at the bottom of the second conveying bin 12 and the two first conveying bins 11, serving as the initial area for the corn stalks to enter, and is connected to these conveying bins. When the corn stalks are conveyed to the crushing bin 131, the crushing component 132 starts working to efficiently crush the stalks. The crushed stalks are then discharged through multiple discharge ports 133 located at the bottom of the crushing bin 131. In order to ensure a smooth connection between the crushing bin 131 and the conveying bin, a switching component 134 is provided above the crushing bin 131, which can adjust the connection status between the crushing bin 131 and the first conveying bin 11 and the second conveying bin 12, thereby ensuring that the actual harvesting conditions of corn on both sides or feed beans on both sides are met, and also ensuring that the corn stalks can be processed quickly and efficiently in a short time. The feed crushing mechanism 13 not only improves the processing efficiency of corn stalks, but also ensures the continuity and stability of the entire harvesting process.

[0049] Under some needs, farmers need to recycle straw. For example, if straw needs to be recycled, a collection bin for collecting corn straw and bean straw can be optionally installed on the outside of the crushing bin 131, and a conveying dragon can be placed in the collection bin. In order to realize the recycling function of the crushed straw, the end of the collection bin can be equipped with a lifting and conveying equipment to transport the crushed straw upward without discharging it in the farmland, and finally the crushed straw can be lifted and transported to the accompanying vehicle.

[0050] See also Figure 3 、 Figure 7 and Figure 10 As shown, in some examples, further, the crushing assembly 132 includes: a cutting roller 1321 and a drive motor 1322. The cutting roller 1321 is rotatable around its own axis and is arranged in the inner cavity of the crushing bin 131. A plurality of cutting blades arranged in a circumferential direction are provided in the cutting roller 1321 at positions corresponding to the first conveying bin 11 and the second conveying bin 12. The drive motor 1322 is fixedly mounted on the side wall of the crushing bin 131. A coupling is provided on the output end of the drive motor 1322 and is connected to the cutting roller 1321.

[0051] It can be understood that the crushing component 132 is responsible for crushing the corn stalks, and the cutting roller 1321, as the main executive part of the crushing component 132, is placed in the inner cavity of the crushing bin 131 and can rotate around its own axis. The multiple circumferentially arranged cutting blades in the cutting roller 1321 are set at corresponding positions with the first conveying bin 11 and the second conveying bin 12, ensuring precise alignment with the conveying bins, thereby achieving precise cutting of the corn stalks. The drive motor 1322 is fixedly mounted on the side wall of the crushing bin 131 to provide the required power for the cutting roller 1321. The straw end cut by the cutting roller 1321 is evenly discharged through the discharge port 133 to the ground as fertilizer.

[0052] See also Figure 10 and Figure 11 As shown, in some examples, further, the switching assembly 134 includes: a micro motor 1341, a first rotating shaft 1342, a second rotating shaft 1343, a protrusion 1344 and an instantaneous electromagnetic valve 1345, the micro motor 1341 is fixedly mounted on the side wall of the crushing bin 131, the micro motor 1341 is used to control the guide state of the baffles 20 in the first conveying bin 11 and the second conveying bin 12, and each baffle 20 can rotate around the first rotating shaft 1342 at its end; the second rotating shaft 1343 is movably connected to the output end of the micro motor 1341 through a sliding spline, and the second rotating shaft 1343 runs through multiple first rotating shafts. A rotating shaft 1342; three protrusions 1344 are fixedly mounted on the outer wall of the second rotating shaft 1343, and each first rotating shaft 1342 is provided with a bayonet corresponding to the protrusion 1344; a momentary solenoid valve 1345 is fixedly mounted on the top of the outer wall of the crushing bin 131, and is used to control the position of the second rotating shaft 1343 to realize the rotation angle of the baffle 20 in the first conveying bin 11 and the second conveying bin 12, and the two protrusions 1344 located on the edge are clamped into one end of the first rotating shaft 1342 in the two first conveying bins 11; the other protrusion 1344 is clamped into the other end of the first rotating shaft 1342 in the second conveying bin 12.

[0053] It should be noted that, in this example, the switching component 134 is designed to ensure that the equipment can flexibly switch the connection status between the two first conveying bins 11 and the middle second conveying bin 12 and the crushing bin 131 in different farmland environments, especially when turning around, so as to adapt to the changes in the positions of corn and fodder bean crops. The micro motor 1341 is the power source of the switching component 134, which is fixed on the side wall of the crushing bin 131 and is mainly responsible for controlling the guide state of the baffle 20. These baffles 20 can rotate around the first rotating shaft 1342 at their ends to change the guide of the conveying bin. The second rotating shaft 1343 is the power transmission part output by the micro motor 1341, which is connected to the micro motor 1341 through a sliding spline. The three protrusions 1344 on the shaft 1343 correspond to the bayonet on each first rotating shaft 1342, so that when the second rotating shaft 1343 rotates, the protrusions 1344 will drive the first rotating shafts 1342 on both sides or in the middle, thereby changing the position of the baffle 20. The instantaneous solenoid valve 1345 controls the displacement of the second rotating shaft 1343. When the equipment needs to turn around, the instantaneous solenoid valve 1345 will control the position of the second rotating shaft 1343 so that the protrusions 1344 are engaged in the first rotating shaft 1342 without flipping up the baffle 20. In this way, when the positions of corn and fodder beans change, the equipment can switch the connection state through the switching component 134, ensuring that the equipment can still be harvested efficiently after turning around, without the need for multiple agricultural machines.

[0054] See also Figure 12 As shown, it should also be noted that due to the different needs of farmers for feed, the processing methods of the two types of straw are different. Some farmers will process crops into a mixed crushed material of corn straw and feed beans as feed, that is, the feed contains corn straw, feed bean straw and feed beans; therefore, the switching component 134 provided in this example can also be set to another embodiment, and its switching action is to uniformly switch all the first conveying bins 11 and the second conveying bins 12, rather than switching the first conveying bin 11 and the second conveying bin 12 independently, that is, the output end of the micro motor 1341 is directly connected to the first rotating shaft 1342 is connected to the second rotating shaft 1343, and the other structures are not set. By adopting this solution, all the baffles 20 can be directly controlled by the micro motor 1341 to open and close and rotate. When all the baffles 20 are rotated, the ends of the first conveying bin 11 and the second conveying bin 12 can be closed. With the conveying action of the mixing conveying roller 19, the fresh corn stalks and the whole crop of fodder beans entering the first conveying bin 11 and the second conveying bin 12 enter the crushing mechanism for synchronous mixing and crushing. After the crushing is completed, a mixed feed containing corn stalks, fodder bean stalks and fodder beans is obtained.

[0055] It can be seen that this device can be set up in another working mode. The design of synchronously driving the two conveying bins by a micro motor 1341 can avoid the setting of a complex transmission mechanism and simplify the structure of the device. At the same time, compared with the method of independently controlling the two bin baffles 20, synchronous control can more flexibly adjust the ratio of the two raw materials, produce mixed feeds with different ingredients, and meet personalized feed needs. In addition, the synchronous crushing of the two raw materials can also improve the mixing uniformity of the feed. Therefore, this working mode provides farmers with more feed ratio options, expands the application range of the feed processing device, and improves its adaptability and practicality.

[0056] In addition, compared with the single long bin design, this solution increases the number of conveying bins and sets up a longer cutting section, which can better alleviate the problem of overload of a single conveying bin and improve the adaptability of the device, so that it can smoothly convey more types and larger quantities of straw raw materials, reduce the risk of raw material blockage, and make the processing process smoother.

[0057] See also Figure 1 and Figure 2 As shown, in some examples, further, the fresh corn cob harvesting mechanism 2 includes: a corn cob conveying bin 21 and a corn cob harvesting cover 22, the corn cob conveying bin 21 is movably connected to the corn cob processing mechanism 4, a corn cob harvesting cover 22 is provided on the other end of the corn cob conveying bin 21, an ear picking roller assembly 23 is provided on one end of the corn cob harvesting cover 22 in the forward direction, and a corn cob conveying dragon 24 is also provided in the corn cob harvesting cover 22.

[0058] It can be understood that the fresh corn cob harvesting mechanism 2 is designed to ensure that the corn can be effectively harvested and conveyed to the processing mechanism. In the forward direction of the corn cob harvesting cover 22, the cob picking roller assembly 23 plays the role of picking corn cobs. When the machine moves forward, the cob picking roller assembly 23 will rotate and pick the corn cobs, and then convey them to the corn cob conveying bin 21. In order to ensure that the corn cobs can be smoothly conveyed from the harvesting cover to the conveying bin, the corn cob harvesting cover 22 is also equipped with a corn cob conveying dragon 24, which collects the corn collected by the wider fresh corn cob harvesting mechanism 2 and conveys it through the middle corn cob conveying bin 21.
