Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and in particular relates to an electric-driven corn harvester. Background Art

[0002] Corn is one of my country's three major staple crops and a high-quality feed, pharmaceutical, and chemical raw material. Corn kernels and corn stalks are valuable resources, and corn is cultivated extensively in my country. With the modernization of agriculture, corn harvesters have become widely used, significantly reducing farmers' labor intensity and burden, and are widely welcomed by farmers.

[0003] A corn harvester is an agricultural machine that performs multiple tasks simultaneously, including plucking, stacking, and returning corn stalks to the field when the corn is ripe. However, existing corn harvesters have complex structures. To accommodate larger grain storage spaces, the granary is enlarged and raised. However, when collecting corn cobs, the high granary easily damages them. Corn cobs also often accumulate on the inner side of the granary near the harvester's husk removal mechanism, wasting storage space outside the granary. Furthermore, the granary can only unload grain at a limited height, making it difficult to lower the unloading height and adjust the amount of corn cobs to be dumped according to actual conditions. For example, if a corn transport truck is nearly full and all the corn cobs are dumped in one go, the truck will not be able to fit any more. If no more corn cobs are added, the remaining space in the truck will be wasted. To achieve energy conservation, environmental protection, and sustainable development, modern agriculture has placed increasingly stringent requirements on ecology, energy conservation, and environmental protection. The demand for low-emission, low-noise powered agricultural machinery is becoming increasingly urgent in special agricultural production environments. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] An embodiment of an electric-driven corn harvester of the present invention is as follows: Figures 1 to 7 As shown, the electric-driven corn harvester includes an ear picking device, a husking device, a crushing and returning device, a granary device, and a traveling device. The ear picking device, the husking device, the crushing and returning device, and the granary device are all driven by their corresponding independent motors. The battery 16 or the generator / motor 17 directly supplies energy to the motors of each device. The battery 16 is electrically connected to the generator / motor 17, the ear picking device motor 8, the husking device motor 14, the crushing and returning device motor 18, and the electric cylinder motor 29 in the granary device and the granary device motor 31. The traditional belt drive is replaced by an electric circuit, which reduces the number of transmission components, improves the transmission efficiency, and reduces the complexity of the harvester. At the same time, the traveling device is powered by the engine 26 and / or the battery 16 to drive the harvester to move, thereby achieving independent control of the speed of each device of the harvester, reducing the burden on the engine 26, improving the working conditions, shortening the power transmission chain, improving the transmission efficiency, ensuring the power and endurance requirements of the harvester, and achieving the goals of energy saving, emission reduction, and noise reduction.

[0028] Reference Figure 1The ear-picking device includes a plucking chain 1, a plucking gear box 2, a transmission shaft 3, a left plucking roller 4, a right plucking roller 5, an ear-picking plate 6, an ear-picking gear box 7, an ear-picking device motor 8, a first elevator 9, a harvesting platform auger 10, and a second elevator 11. The output shaft of the ear-picking device motor 8 is connected to multiple ear-picking gear boxes 7 via bevel gears. Pairs of plucking chains 1 are installed at the front end of the ear-picking device. The plucking chains 1 are mounted on sprockets, which are connected to the plucking gear boxes 2. The plucking gear boxes 2 are connected to the plucking gear boxes 7 via the transmission shaft 3. The paired plucking chains 1 are connected to the plucking gear boxes 7 via their corresponding plucking gear boxes 2 and transmission shaft 3, and the paired plucking chains rotate relative to each other. The left and right plucking rollers 4 and 5 are directly connected to the plucking gear boxes 7. There is a height difference between the left ear picking roller 4 and the right ear picking roller 5. The lower ear picking roller is close to the ear picking plate, so that the removed corn ears can smoothly pass through the ear picking plate 6 and roll into the first elevator 9. The ear picking device motor 8 outputs power, drives the ear picking gear box 7 through the bevel gear to drive the straw chain 1, the left ear picking roller 4, and the right ear picking roller 5 to work and harvest corn. The pulling force generated by the rotation of the left ear picking roller 4 and the right ear picking roller 5 separates the corn ears and the straw from each other. Due to the height difference between the left ear picking roller 4 and the right ear picking roller 5, the corn ears roll through the ear picking plate 6 and fall into the first elevator 9. The straw is squeezed by the two ear picking rollers and runs backward to the crushing and returning device. The output shaft of the ear picking device motor 8 is directly connected to the drive shaft of the first elevator 9, and at the same time drives the cutting platform auger 10 and the second elevator 11 to work through the chain drive. The first elevator 9 transports the corn cobs to the second elevator 11 through the cutting platform auger 10, and the second elevator 11 then directly transports the corn cobs to the peeling device.

[0029] Reference Figure 2The peeling device includes a metal spiral peeling roller 12, a rubber peeling roller 13, a peeling device motor 14, a first spindle 15, a second spindle 25, and a peeling device frame 51. In the peeling device, the output shaft of the peeling device motor 14 is directly connected to the first spindle 15, and the first spindle 15 and the second spindle 25 are connected through a coupling, so that the peeling device motor 14 drives the first spindle 15 and the second spindle 25 to rotate. The metal spiral peeling roller 12 and the rubber peeling roller 13 are distributed at intervals in the peeling device frame 51. The first spindle 15 and the second spindle 25 are connected to some of the metal spiral peeling rollers 12 and the rubber peeling roller 13 through bevel gears. When the peeling device motor 14 is working, the adjacent metal spiral peeling rollers 12 and rubber peeling rollers 13 can rotate relative to each other. The husking device's motor 14 rotates the two main shafts, thereby driving the metal spiral husking roller 12 and the rubber husking roller 13 to rotate. The threads of the metal spiral husking roller 12 cause the corn cob to move downward, while the rubber husking roller 13 is used to grab and tear the husks of the corn cob. As the metal spiral husking roller 12 and the rubber husking roller 13 rotate, the corn cob is husked and conveyed into the grain bin 28. The husks are then conveyed downward to the crushing and returning device as the husking rollers rotate. In other embodiments, the first and second main shafts 15 and 25 can be combined into a single main shaft.

[0030] The comminution and corn-returning device includes a comminution and corn-returning motor 18, a shredder blade 19, and a mopping roller 20. The shredder blades 19 are mounted on a cylindrical body, with a mopping roller 20 positioned behind the body. The comminution and corn-returning motor 18 directly drives the cylindrical body, which in turn drives the shredder blades 19 to shred the corn stalks and husks that have fallen from the ear picking and husking devices. These shredder blades are then crushed onto the ground by the mopping roller 20 for return to the field.

[0031] Reference Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 The granary device includes a bracket 27, a granary 28, an electric cylinder motor 29, a reinforcing cross bar 30, a granary device motor 31, an electric cylinder 32, a bracket ear 33, a hinge seat 34, a cross bar ear 35, a granary auxiliary plate 36, a push plate 37, a granary fill light 38, a camera 39, a drive shaft 40, a chain 41, a slide 42, a slider 43, a grain unloading auxiliary plate 44, a rocker arm 45, a card plate 46, a No. 2 hinge 47, a No. 2 side panel 48, a No. 1 hinge 49, and a No. 1 side panel 50.

[0032] A bracket 27 is installed at the bottom of the granary device. The top of bracket 27 is hingedly connected to one side of the top of granary 28 via a hinge 34. Bracket 27 is provided with a bracket lug 33, to which an electric cylinder motor 29 and an electric cylinder 32 are hingedly connected. A reinforcing crossbar 30 is installed on the outer wall of the granary. A crossbar lug 35 is provided on the reinforcing crossbar 30, and the output shaft of the electric cylinder 32 is hingedly connected to the crossbar lug 35. The electric cylinder motor 29 drives the electric cylinder 32 to extend and retract, causing the output shaft of the electric cylinder 32 to extend and lift the reinforcing crossbar 30, causing the granary 28 to rotate relative to the hinge 34 to complete the flip and unloading of grain. Alternatively, the output shaft of the electric cylinder 32 can be retracted to lower the granary 28.

[0033] A silo motor 31 is mounted on the granary 28. The motor's output shaft is connected to a drive shaft 40, which in turn is connected to a silo auxiliary plate 36, driving the plate 36 to swing within the granary. One side of the plate 36 is fixed to the drive shaft 40, near the upper edge of the granary's inner wall. Its main body is pivotally mounted within the granary 28. A slideway 42 is mounted on a sidewall perpendicular to the granary's inner wall where the drive shaft 40 resides. A slider 43 slides on the slideway 42. A closed-loop chain 41 is mounted on this sidewall, driven by the motor 31 via a sprocket. A driven sprocket is mounted on the sidewall to tension the chain 41. One side of the chain 41 is parallel to the slideway 42, and a slider 43 is mounted on the chain 41. Operation of the motor 31 drives the slider 43 within the slideway 42. A push plate 37 is vertically arranged in the granary 28 and is parallel to the side wall where the granary auxiliary plate 36 is located. The slider 43 passes through the side wall of the granary 28 and is fixedly connected to the push plate 37. The granary device motor 31 drives the push plate 37 to slide in the granary 28.

[0034] When the corn cobs begin to be stacked in the granary 28, the granary device motor 31 starts to work, driving the granary auxiliary plate 36 and the push plate 37 to operate. The granary auxiliary plate 36 and the push plate 37 are linked to each other so that the push plate 37 is always located below the movable end of the granary auxiliary plate 36. The granary auxiliary plate 36 tilts, and at the same time, the push plate 37 moves to the lower side of the movable end of the granary auxiliary plate 36, so that the corn cobs enter the outer area of the granary 28 along the granary auxiliary plate 36 and the push plate 37, thereby preventing the peeled corn cobs from being injured. The corn cobs are preferentially accumulated in the outer area of the granary 28; when the height of the corn cobs accumulated in the granary exceeds the push plate 37, the granary device motor 31 drives the granary auxiliary plate 36 and the push plate 37 to operate, causing the granary auxiliary plate 36 to flip downward and approach the inner wall of the granary, and the push plate 37 to move close to the inner wall of the granary, so that the corn cobs can be accumulated in the inner area of the granary, ensuring that the outer and inner areas of the granary are filled with corn cobs, while preventing the corn cobs from being damaged by being hit, and fully utilizing the volume of the granary. Because the corn cobs have a certain length, when the corn cobs are poured into and accumulated in the same area of the granary, the corn cobs are not likely to slide to other areas of the granary. The granary of the present invention prevents the corn cobs from accumulating in a certain position in the granary, fully utilizing the volume of the granary, reducing the number of times the granary is unloaded, and improving work efficiency. A camera 39 and a fill light 38 are installed above the granary. During operation, camera 39 monitors the accumulation of corn ears in the granary and transmits signals to control the operation of the granary device motor 31. The fill light 38 facilitates the camera 39 to observe the granary in dark or nighttime conditions. The camera 39 detects the accumulation height and sends a signal to the granary device motor 31 to rotate it a certain angle, which is conventional technology and will not be further described.

[0035] Four rocker arms 45 and a card plate 46 are installed on the side of the granary's tilting side, and side panels 50 and 48 are sequentially arranged on this side of the granary from top to bottom, which are used to close or open this side of the granary. The bottom of side panel 50 is hinged to the top of side panel 48 via hinge 49, and the bottom of side panel 48 is hinged to the bottom of the granary via hinge 47. A card plate 46 is provided on each side of the outer wall of side panel 50 and side panel 48. One end of the rocker arm 45 is hinged to the main body of the granary, and the other end is clamped on the corresponding card plate 46. Auxiliary plates 44 for unloading grain are provided on both sides of the inner wall of side panel 50 and side panel 48. When the granary is in a closed state, the swing arms 45 are all stuck on the corresponding card plates 46; when the swing arms 45 and the card plates 46 on the No. 1 side panel 50 are opened, the No. 1 side panel 50 flips over relative to the No. 1 hinge 49, and the corn ears that are higher than the No. 2 side panel 48 roll along the No. 1 side panel 50 and in a specific direction to the outside of the granary under the obstruction of the grain unloading auxiliary plate 44. Then, the electric cylinder motor 29 drives the electric cylinder 32 to work, so that the granary 28 tilts at an angle, and the swing arms 45 and the card plates 46 on the No. 2 side panel 48 are opened, and the No. 2 side panel 48 flips over relative to the No. 2 hinge 47 for unloading grain, so that all the corn ears roll out as the granary 28 tilts, so that the granary can unload grain according to the actual required unloading height.

[0036] A camera 39, a granary auxiliary plate 36 and a push plate 37 are arranged in the granary 28. Under the observation of the camera 39, the granary auxiliary plate 36 and the push plate 37 are controlled to rotate and move to prevent the corn cobs from being damaged after being peeled, ensure that the outside and inside of the granary are filled with corn cobs, and make full use of the granary volume. The two side panels of the granary 28 enable the granary 28 to unload grain according to the actual unloading height required.

[0037] When the electric corn harvester is working, the engine 26 can be used as an energy replenishment device or as a power source for the traveling device. When the engine 26 is working, a part of the power is converted from the generator / motor 17 into electrical energy through the torque coupling device 24 to drive the ear picking device motor 8, the peeling device motor 14, the crushing and returning device motor 18, the electric cylinder motor 29 and the granary device motor 31 to work, and the excess power is stored in the battery 16. The other part of the power is transmitted to the traveling device to drive the harvester to move. The engine serves as both an energy replenishment device and a power source for the traveling device. While ensuring the power of the harvester's operating devices, it also meets the harvester's endurance requirements, achieving energy-saving operation and long-endurance operation of the harvester.

[0038] The traveling device includes a wheel-side speed reducer 21, a differential 22, and wheels 23. The traveling device can be powered by either the engine 26 or the battery 16 alone. This power is coupled through the torque coupling device 24, the differential 22, and the wheel-side speed reducer 21 to drive the wheels 23, thereby moving the harvester. Alternatively, the engine 26 and the battery 16 can be used together to generate power. This power is coupled through the torque coupling device 24 to power the traveling device, thereby driving the harvester.

[0039] Battery 16 can power the ear picking device motor 8, the peeling device motor 14, the crushing and returning device motor 18, the electric cylinder motor 29, and the grain storage device motor 31 to drive the various operating devices of the electric drive corn harvester. It can also drive the wheels 23 to rotate through the generator / motor 17, the torque coupling device 24, the differential 22, and the wheel-side reducer 21 to drive the harvester. The battery can drive the various operating devices of the harvester and serve as a power source for the driving device. While ensuring the power of the harvester's operating devices, it also reduces the load on the engine, improves the working conditions, and achieves the goals of energy conservation, emission reduction, and noise reduction.

[0040] If the harvester is working at a low load and the battery 16 SOC is high, the connection between the engine 26 and the generator / motor 17 can be cut off, and the battery 16 can be used to power the motors in each operating device separately; if the harvester is working at a low load and the battery 16 SOC is low, the engine 26 drives the generator / motor 17 through the torque coupling device 24 to generate electricity, power the various motors of the operating device, and stores the excess power in the battery 16; if the harvester is working at a high load and the battery 16 SOC is high, the engine 26 drives the generator / motor 17 through the torque coupling device 24 to While the electric motor in the operating device is supplying power, the battery 16 also outputs energy to ensure the smooth operation of the harvester when working under high load; if the harvester is in a high-speed transport condition and the battery 16 SOC is high, the engine 26 and the battery 16 simultaneously supply energy to the driving walking device through the torque coupling device 24 to reduce the load of the engine 26 and improve the working condition; if the harvester is in a low-speed transport condition and the battery 16 SOC is high, the battery 16 separately supplies energy to the walking device through the generator / motor 17 and the torque coupling device 24 to drive the harvester to move, thereby achieving the purpose of energy saving, emission reduction and noise reduction.

[0041] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and alterations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
