Description

Technical Field

[0001] This invention relates to the field of crop harvesters, specifically a harvester with the function of harvesting lodged barley stalks and ears. Background Technology

[0002] Barley is not only an important biological resource for the development of characteristic agricultural industries in Tibetan areas, but it also plays a vital role in increasing farmers' income and improving the quality of life and health of local people. It has irreplaceable attributes. Barley is a type of cereal barley in the genus Horde of the Poaceae family. Because its inner and outer husks are separated and the grains are naked, it is also called naked barley, naked barley, or naked barley. It is mainly produced in Tibet, Qinghai, Sichuan, Yunnan and other places in China, and is the staple food of the Tibetan people.

[0003] After barley matures, existing large-scale grain combine harvesters can achieve automated harvesting. However, during the planting and growth of barley, due to weather and variety issues, large areas of barley may occasionally lodging. When the harvester tries to harvest these lodged barley stalks, it is difficult to harvest them smoothly because they are lying on the ground. This affects the harvesting progress and the harvesting effect, and also wastes barley stalks and ears. Summary of the Invention

[0008] The first reset mechanism includes two symmetrically arranged first connecting blocks fixedly connected to the side wall of the reel shaft, and a second T-shaped guide rod is inserted into the side wall of the first connecting block. A first spring is sleeved on the side wall of the second T-shaped guide rod, and a second connecting block is fixedly connected to one end of the second T-shaped guide rod. The second connecting block is fixed to the lower side wall of the sliding plate.

[0009] The vibration mechanism includes a striking plate fixedly connected to the end of the reel shaft, and a plurality of arrayed push rods are fixedly connected to the upper side wall of the sliding plate. The end of the reel shaft is connected to a moving rod through a second reset mechanism, and the lower end of the moving rod slides on the side wall of the push rod.

[0010] The second reset mechanism includes a third connecting block fixedly connected to the end of the reel shaft, and a moving rod inserted into the upper side wall of the third connecting block. The side wall of the moving rod is fixedly sleeved with a first limiting ring and a second limiting ring, and the side wall of the moving rod is sleeved with a second spring.

[0011] The first pushing mechanism includes an arc-shaped plate, which is connected to the side wall of the cutting table via a moving mechanism. The arc-shaped plate includes an arc-shaped surface, and one end of the sliding plate slides on the arc-shaped surface.

[0012] The moving mechanism includes a mounting plate fixedly connected to the side wall of the cutting table, and a sleeve rod fixedly connected to the side wall of the mounting plate. A sleeve is fitted on the side wall of the sleeve rod, and the other end of the sleeve is fixed to the side wall of the arc-shaped plate. A threaded sleeve is fixedly connected to the side wall of the arc-shaped plate, and a threaded rod is fitted on the side wall of the threaded sleeve. The other end of the threaded rod is rotatably connected to the side wall of the mounting plate.

[0014] The second pushing mechanism includes a pushing block fixedly connected to the side wall of the sealing plate, and the pushing block includes an inclined surface. An L-shaped pushing plate is fixedly connected to the upper side wall of the arc plate, and the upper end of the pushing plate slides on the inclined surface.

[0015] The beneficial effects of this invention are:

[0016] (1) The harvester of the present invention, which has the function of harvesting lodged barley stalks and ears, is equipped with an air extraction mechanism, etc. When it is necessary to harvest lodged barley stalks and ears, the moving mechanism moves the arc-shaped plate towards the reel. At this time, when the reel rotates, it drives the reel shaft and the reel rod to rotate together. When one end of the sliding plate abuts against the arc surface and slides along the side wall of the arc plate, it pushes the sliding plate to slide into the reel shaft. At the same time, the first spring contracts, so that the through hole is connected to the reel rod. Furthermore, when the arc plate moves, it drives the push plate to move synchronously, so that the upper end of the push plate abuts against the inclined surface and slides on its surface, thereby pushing the push block and the sealing plate to move upward, thereby moving the reel rod. When the end of the reel shaft is open, the rotation of the reel shaft drives the fan to rotate synchronously, thereby expelling the air inside the reel shaft. This air is then drawn through the connecting pipe, the reel shaft, and the lever, which can lift up the lodged barley stalks and ears, making them easier to harvest. This makes harvesting lodged barley stalks and ears more convenient, faster, more efficient, and results in better harvesting. It also avoids wasting barley stalks and ears. Furthermore, when the end of the sliding plate passes the arc plate, the sliding plate can be reset under the action of the first spring, causing the sliding plate to block the lever and stop the lever from drawing air. At this point, the suction of barley stalks and ears is stopped, ensuring the harvesting and conveying effect.

[0017] (2) The harvester of the present invention, which has the function of harvesting lodged barley stalks and ears, is equipped with a vibration mechanism, etc. When harvesting lodged barley stalks and ears, when the sliding plate moves, it drives the push rod to move synchronously. When the push rod abuts against the lower end of the moving rod, it pushes the moving rod to move upward. At the same time, the third spring contracts, so that the moving rod strikes the striking plate. When the push rod passes the lower end of the moving rod, the moving rod can move downward to reset under the action of the third spring. This process is repeated to reciprocate the striking plate and vibrate it. The vibration is transmitted to the reeling shaft, the reeling rod, and the filter screen at the bottom of the reeling rod, thereby preventing impurities from adhering to the surface, ensuring the reeling effect, and the adsorption effect on lodged barley stalks and ears.

[0031] like Figures 1-9As shown, a harvester of the present invention, which has the function of harvesting lodged barley stalks and ears, includes a header 101 and a reel 102 mounted on the harvester body 1. A support 103 is mounted on the upper side wall of the header 101, and the reel 102 is rotatably connected to the side wall of the support 103 via a reel shaft 104. A reel shaft 105 and a lever 106 are mounted on the reel 102. The reel shaft 104, the reel shaft 105, and the lever 106 are all hollow. Both the reel shaft 104 and the lever 106 have open ends. A filter screen is fixedly connected to the lower end of the lever 106 to prevent clogging. The lever 106 and the reel shaft 105 are internally connected. Multiple arrayed connecting pipes 202 are fixedly connected to the side wall of the reel shaft 104, and the other end of the connecting pipes 202 is fixed to the side wall of the reel shaft 105. A support plate 201 is fixedly connected to the upper side wall of the header 101. Furthermore, the support plate 201 is sleeved on the side wall of the reel shaft 104. Each reel shaft 105 has a first sealing mechanism on its side wall for sealing the upper end of the lever 106, and the support plate 201 has a second sealing mechanism on its side wall for sealing the end of the reel shaft 104. An air extraction mechanism is installed inside the reel shaft 104 to drive the lower end of the lever 106 to extract air. When encountering lodged barley stalks, this mechanism allows the lever 106 to... The lower end of 6 performs an air extraction operation, which can adsorb the lodged barley stalks and ears upward, thereby lifting them up for easy harvesting. This makes harvesting the lodged barley stalks and ears more convenient, faster, more efficient, and results in better harvesting. Furthermore, it can vibrate the reeling shaft 105, the reeling rod 106, and the filter screen at the bottom of the reeling rod 106, thereby preventing impurities from adhering to the surface, ensuring the reeling effect, and enhancing the adsorption effect on the lodged barley stalks and ears.

[0032] The air extraction mechanism includes a fixed plate 401 fixedly connected to the inner side wall of the reel shaft 104, and a fixed shaft 402 fixedly connected to the side wall of the fixed plate 401. A fan 403 is fixedly connected to the other end of the fixed shaft 402. When the reel shaft 104 rotates, it drives the fan 403 to rotate synchronously, thereby expelling the air inside the reel shaft 104. The air is then extracted through the connecting pipe 202, the reel shaft 105, and the lever 106, which can adsorb the lodged barley stalks upward.

[0033] The first sealing mechanism includes a sliding plate 501 inserted at the end of the reeling shaft 105, and the sliding plate 501 is connected to the side wall of the reeling shaft 105 through a first reset mechanism. The upper side wall of the sliding plate 501 has a plurality of arrayed through holes 502, and the movement of the sliding plate 501 is driven by a first pushing mechanism. The end of the reeling shaft 105 is provided with a vibration mechanism for striking and vibrating it. During normal harvesting, the through holes 502 are offset from the upper end of the lever 106, and the sliding plate 501 can seal the upper end of the lever 106. At this time, the lower end of the lever 106 will not be pumped out. When it is necessary to harvest the lodged barley stalks, the sliding plate 501 is pushed into the reeling shaft 105 by the first pushing mechanism. At the same time, the first spring 603 contracts, so that the through holes 502 are connected to the lever 106.

[0034] The first reset mechanism includes two symmetrically arranged first connecting blocks 601 fixedly connected to the side wall of the reel shaft 105. A second T-shaped guide rod 602 is inserted into the side wall of the first connecting block 601. A first spring 603 is sleeved on the side wall of the second T-shaped guide rod 602. A second connecting block 604 is fixedly connected to one end of the second T-shaped guide rod 602. The second connecting block 604 is fixed to the lower side wall of the sliding plate 501 and plays a guiding and reset role for the movement of the sliding plate 501.

[0035] The vibration mechanism includes a striking plate 701 fixedly connected to the end of the reel shaft 105, and a plurality of arrayed push rods 702 fixedly connected to the upper side wall of the sliding plate 501. The end of the reel shaft 105 is connected to a moving rod 703 via a second reset mechanism, and the lower end of the moving rod 703 slides on the side wall of the push rod 702. When the sliding plate 501 moves, it drives the push rod 702 to move synchronously. When the push rod 702 abuts against the lower end of the moving rod 703, it pushes the moving rod 703 upward. When the third spring 804 contracts, the moving rod 703 strikes the striking plate 701. When the pushing rod 702 passes the lower end of the moving rod 703, the moving rod 703 can move downward and reset under the action of the third spring 804. This process is repeated to reciprocate the striking plate 701 and transmit the vibration to the reeling shaft 105, the lever 106, and the filter screen at the bottom of the lever 106, thereby preventing impurities from adhering to the surface, ensuring the reeling effect, and improving the adsorption effect on lodged barley stalks and ears.

[0036] The second reset mechanism includes a third connecting block 801 fixedly connected to the end of the reel shaft 105, and a moving rod 703 inserted into the upper side wall of the third connecting block 801. A first limiting ring 802 and a second limiting ring 803 are fixedly sleeved on the side wall of the moving rod 703, and a second spring 804 is sleeved on the side wall of the moving rod 703, which guides and resets the movement of the moving rod 703.

[0037] The first pushing mechanism includes an arc-shaped plate 901, which is connected to the side wall of the header 101 via a moving mechanism. The arc-shaped plate 901 includes an arc-shaped surface 902, and one end of the sliding plate 501 slides on the arc-shaped surface 902. When it is necessary to harvest the lodged barley stalks, the moving mechanism causes the arc-shaped plate 901 to move towards the reel 102. At this time, when the reel 102 rotates, it drives the reel shaft 105 and the lever 106 to rotate together. When one end of the sliding plate 501 abuts against the arc-shaped surface 902 and slides along the side wall of the arc-shaped plate 901, it pushes the sliding plate 501 to slide into the reel shaft 105. At the same time, the first spring 603 contracts, which makes the through hole 502 connected to the lever 106.

[0038] The moving mechanism includes a mounting plate 1001 fixedly connected to the side wall of the cutting table 101, and a sleeve rod 1003 fixedly connected to the side wall of the mounting plate 1001. A sleeve 1002 is sleeved on the side wall of the sleeve rod 1003, and the other end of the sleeve 1002 is fixed to the side wall of the arc plate 901. A threaded sleeve 1004 is fixedly connected to the side wall of the arc plate 901, and a threaded rod 1005 is sleeved on the side wall of the threaded sleeve 1004. The other end of the threaded rod 1005 is rotatably connected to the side wall of the mounting plate 1001. A motor 1006 is fixedly connected to the side wall of the mounting plate 1001, and the output end of the motor 1006 is fixed to one end of the threaded rod 1005. When the motor 1006 is started, the rotation of the motor 1006 drives the rotation of the threaded rod 1005, thereby driving the arc plate 901 to move. During normal use, the sliding plate 501 does not contact the arc plate 901.

[0039] The second sealing mechanism includes a connecting plate 301 fixedly connected to the side wall of the support plate 201, and two symmetrically arranged third T-shaped guide rods 302 are fixedly connected to the upper side wall of the connecting plate 301. A third spring 304 is sleeved on the side wall of the third T-shaped guide rod 302, and a moving plate 303 is sleeved on the side wall of the third T-shaped guide rod 302. A sealing plate 305 is fixedly connected to the side wall of the moving plate 303, and the movement of the sealing plate 305 is driven by the second pushing mechanism. During normal use, the sealing plate 305 seals the end of the reel shaft 104. At this time, when the fan 403 rotates, it cannot perform the air extraction operation. When it is necessary to harvest the lodged barley stalks, the sealing plate 305 is pushed upward by the second pushing mechanism, thereby opening the end of the reel shaft 104.

[0040] The second pushing mechanism includes a pushing block 1101 fixedly connected to the side wall of the sealing plate 305, and the pushing block 1101 includes an inclined surface 1102. An L-shaped pushing plate 1103 is fixedly connected to the upper side wall of the arc plate 901, and the upper end of the pushing plate 1103 slides on the inclined surface 1102. When the arc plate 901 moves, it drives the pushing plate 1103 to move synchronously, so that the upper end of the pushing plate 1103 abuts against the inclined surface 1102 and slides on its surface, thereby pushing the pushing block 1101 and the sealing plate 305 to move upward, thereby opening the end of the reel shaft 104.

[0041] Working principle: When working, firstly, when it is necessary to harvest the lodged barley stalks, the moving mechanism moves the arc plate 901 towards the reel 102. At this time, when the reel 102 rotates, it drives the reel shaft 105 and the lever 106 to rotate together. When one end of the sliding plate 501 abuts against the arc surface 902 and slides along the side wall of the arc plate 901, it pushes the sliding plate 501 to slide into the reel shaft 105. At the same time, the first spring 603 contracts, which makes the through hole 502 connected to the lever 106.

[0042] When the arc plate 901 moves, it drives the push plate 1103 to move synchronously, so that the upper end of the push plate 1103 abuts against the inclined surface 1102 and slides on its surface, thereby pushing the push block 1101 and the sealing plate 305 to move upward, thereby opening the end of the reel shaft 104. At this time, when the reel shaft 104 rotates, it drives the fan 403 to rotate synchronously, thereby expelling the air in the reel shaft 104, and then drawing air through the connecting pipe 202, the reel shaft 105 and the lever 106, which can adsorb the lodged barley stalks and ears upward, thereby lifting them up and making them easier to harvest. This makes it easier to harvest the lodged barley stalks and ears, making it more convenient and faster to use, more efficient and better in harvesting, while avoiding the waste of barley stalks and ears.

[0043] When the end of the sliding plate 501 passes the arc plate 901, the sliding plate 501 can be reset under the action of the first spring 603, so that the sliding plate 501 blocks the lever 106, thereby stopping the lever 106 from pumping air. At this time, the adsorption of barley stalks and ears stops, ensuring the harvesting and conveying effect.

[0044] Meanwhile, when the sliding plate 501 moves, it drives the push rod 702 to move synchronously. When the push rod 702 abuts against the lower end of the moving rod 703, it pushes the moving rod 703 to move upward. At the same time, the third spring 804 contracts, causing the moving rod 703 to strike the striking plate 701. When the push rod 702 passes the lower end of the moving rod 703, the moving rod 703 can move downward to reset under the action of the third spring 804. This process is repeated to reciprocate the striking plate 701 and transmit the vibration to the reeling shaft 105, the lever 106, and the filter screen at the bottom of the lever 106, thereby preventing impurities from adhering to the surface, ensuring the reeling effect, and improving the adsorption effect on lodged barley stalks and ears.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
