Description

Technical Field

[0001] The present invention relates to the technical field of crop harvesting, and specifically to a hydraulic self-propelled corn seed and stem combined harvester. Background Art

[0002] A corn seed and stem combined harvester is an agricultural machinery and equipment specifically designed to simultaneously harvest corn kernels and corn straws. This machine combines the functions of traditional harvesting, threshing, and straw processing, greatly improving the efficiency of corn harvesting and reducing the labor demand.

[0003] During operation, the current corn seed and stem combined harvester first cuts the corn straw together with the roots, and then transports the corn straw to the equipment through the cooperation of the auger unit and the conveyor chain. During this process, through the cooperation of the two, the straw moves horizontally while moving downward, and the straw is segmented by the set cutting knife for subsequent processing. Finally, the corn is separated from the straw and enters the subsequent corn peeling equipment and corn threshing equipment for the next operation process.

[0004] The following problems exist in the above process: During the process of transporting and cutting the corn straw, it is necessary to keep the corn straw in a vertically downward state as much as possible during transportation to ensure that the corn can fall into the designated area after being cut by the cutting knife multiple times. The state of the straw during transportation depends on its initial inclination state. Therefore, the above current cutting method can only harvest the vertically oriented straws. However, for some cases where the initial state of the corn straw is at an inclined angle, although the straw can be moved for cutting, there is a problem that the corn may not fall into the designated area after the straw is cut.

[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] As Figure 1 and Figure 2 shown, a hydraulic self-propelled corn stalk and seed combined harvester includes:

[0036] A fixed steel frame 1, on the right side of the fixed steel frame 1 is fixedly provided with a moving unit 2. The moving unit 2 includes existing external moving wheels. A corn peeling device and a corn threshing device (not shown in the figure) for subsequent processing of harvested corn are jointly provided on the moving unit 2 and the fixed steel frame 1. The front end face of the fixed steel frame 1 is slidably provided with a mounting frame 3 through two mounting rods distributed left and right. An expansion frame 4 is jointly provided between the fixed steel frame 1 and the mounting frame 3.

[0037] As Figure 1 and Figure 2As shown, a plurality of placement racks 5 arranged at equal intervals from front to back are commonly provided on the fixed steel frame 1, the mounting frame 3 and the extension frame 4. The placement racks 5 are successively an inclined section and a horizontal section from left to right, and its inclined section inclines upward from left to right. An installation unit 6 is commonly provided on all the placement racks 5 and the fixed steel frame 1, the mounting frame 3 and the extension frame 4. All the placement racks 5 are successively installed and locked from front to back through the installation unit 6.

[0038] As Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, a harvesting mechanism 7 is commonly provided on all the placement racks 5. An adjacent two placement racks 5 together form a harvesting station. The harvesting mechanism 7 includes a cutting knife 70. A cutting knife 70 and an auger unit 71 with an axis extending along the length direction of the inclined section of the corresponding placement rack 5 are rotatably provided on the lower end surface of the placement rack 5. Two conveying chains 72 distributed front and back are provided on the lower end surface of the inclined section of the placement rack 5. Auxiliary plates I 720 and auxiliary plates II 721 are respectively provided on the circumferential surfaces of the two conveying chains 72 on the same placement rack 5. Both the auxiliary plates I 720 and the auxiliary plates II 721 are V-shaped, and the auxiliary plates I 720 and the auxiliary plates II 721 on the adjacent two conveying chains 72 on the adjacent placement racks 5 cooperate with each other. A driving unit 8 is provided on the fixed steel frame 1.

[0039] It should be noted that the driving unit 8 operates to drive the conveying chain 72 to run and convey the corn straw, and at the same time drives the cutting knife 70 and the auger unit 71 to run synchronously, that is, the auger unit 71 drives the corn straw to move downward, and the cutting knife 70 successively cuts the straw into multiple segments. The movement route of the corn straw is shown in Figure 7 , and secondly, the operation methods of these two parts are both external existing operation technologies.

[0040] During operation, first, install the required extension frame 4 between the mounting frame 3 and the fixed steel frame 1 according to the required harvesting stations. Then, select the required number of placement racks 5 according to the number of required harvesting stations, and integrally lock all the placement racks 5 and the harvesting mechanisms 7 thereon through the mounting unit 6. Connect the conveyor chain 72 in the harvesting mechanism 7 to the drive unit 8. The moving unit 2 operates to synchronously move the fixed steel frame 1, the corn peeling device, and the corn threshing device to the left. During the leftward movement, the drive unit 8 operates to synchronously rotate the two conveyor chains 72 on the same placement rack 5 in opposite directions. The adjacent two conveyor chains 72 on adjacent placement racks 5 cooperate with each other. The auxiliary plate one 720 and the auxiliary plate two 721 on these two conveyor chains 72 are closed and cooperate with each other, keeping the corn straw vertical while driving it to move to the right. At the same time, the agitating unit drives the corn straw to move downward, and the cutting knife 70 rotates to cut the straw. Finally, the straw is cut section by section, and the corn is recycled above the fixed steel frame 1 into the corn peeling device and the corn threshing device for the next processing operation.

[0041] As Figure 1 , Figure 8 and Figure 9 shown, the harvesting mechanism 7 further includes a rotating shaft 73. Four rotationally arranged rotating shafts 73 are rotatably penetrated through the inclined section of the placement rack 5. A sprocket 730 is fixedly sleeved on the rotating shaft 73. The conveyor chain 72 is sleeved on the corresponding two sprockets 730. A plurality of fixing blocks 731 distributed along the length direction are fixedly arranged on the circumferential surface of the conveyor chain 72. A connecting column 732 is slidably arranged back and forth on the end surface of the fixing block 731 away from the corresponding conveyor chain 72. The auxiliary plate one 720 and the auxiliary plate two 721 are fixedly arranged on the corresponding connecting column 732. The vertical thickness of the auxiliary plate one 720 is greater than the vertical thickness of the auxiliary plate two 721. Both ends of the auxiliary plate one 720 are provided with cooperation grooves 733 for cooperating with the corresponding auxiliary plate two 721.

[0042] As Figure 8 and Figure 9 shown, taking the adjacent auxiliary plate one 720 and auxiliary plate two 721 on adjacent placement racks 5 as an example for illustration, arc-shaped strips 734 are fixedly arranged on the end surfaces of the left side sections of the auxiliary plate one 720 and the auxiliary plate two 721 away from the corresponding fixing blocks 731. The inner arc surfaces of the arc-shaped strips 734 face the corresponding auxiliary plate one 720 or auxiliary plate two 721.

[0043] As Figure 8 and Figure 9As shown, a first hydraulic cylinder 735 with an axis extending from front to back and corresponding to the conveying chain 72 one by one is fixedly arranged on the lower end surface of the placing rack 5. A pushing plate 736 is fixedly arranged at the telescopic end of the first hydraulic cylinder 735. The pushing plate 736 successively includes an inclined section and a horizontal section in the horizontal direction from left to right, and its inclined section inclines from left to right in a direction away from the corresponding first hydraulic cylinder 735. A fixing strip 737 is slidably installed through the front and rear of the upper end surface of the fixing block 731, and the fixing strip 737 is fixedly connected to the corresponding connecting column 732.

[0044] During operation, after the placing rack 5 is fixedly installed, the driving unit 8 operates to make the rotating shaft 73 rotate. The rotating shaft 73 drives the corresponding conveying chain 72 to rotate synchronously through the sprocket 730. Among the adjacent two conveying chains 72 on the adjacent placing racks 5, the rear conveying chain 72 rotates counterclockwise and the front conveying chain 72 rotates clockwise. During the rotation of the conveying chain 72, the fixing block 731, the connecting column 732, the first auxiliary plate 720, and the second auxiliary plate 721 thereon are driven to move synchronously. During the process of the moving unit 2 gradually moving leftward, the leftmost first auxiliary plate 720 or the second auxiliary plate 721 on the conveying chain 72 gradually rotates between the adjacent two placing racks 5. During the rotation process, the arc-shaped strips 734 on the first auxiliary plate 720 and the second auxiliary plate 721 assist in capturing the corn straw, facilitating the movement of the straw between the corresponding first auxiliary plate 720 and the second auxiliary plate 721. As the conveying chain 72 gradually moves, the corresponding first auxiliary plate 720 and the second auxiliary plate 721 gradually close and finally press tightly against the corn straw, that is, the two embrace the corn straw from the lower part position of the corn straw, and through the above-mentioned cooperation with the auger unit 71, the corn straw gradually moves to the right and maintains a vertical orientation, facilitating the harvesting of the inclined corn straw. At the same time, during the process of the cutting knife 70 cutting the corn straw, the corn straw is kept in a vertical orientation, avoiding the situation that the corn straw topples during the movement, resulting in the corn cobs deviating from the designated route and being unable to be transferred to the right side of the fixed steel frame 1 and unable to enter the corn peeling equipment and the corn threshing equipment.

[0045] During the above operation process, the first hydraulic cylinder 735 operates to drive the pushing plate 736 to move back and forth through its telescopic end. After the pushing plate 736 moves to the designated position, it stops moving. When the conveying chain 72 drives the fixing block 731 to move, the fixing strip 737 first contacts the inclined section of the pushing plate 736 and finally moves to the end surface of the pushing plate 736 away from the corresponding first hydraulic cylinder 735. Therefore, the distance between the corresponding two fixing strips 737 is controlled in the above way, that is, the distance between the first auxiliary plate 720 and the second auxiliary plate 721 that need to cooperate is controlled, ensuring that the first auxiliary plate 720 and the second auxiliary plate 721 can closely embrace the corn straw and ensuring the vertical orientation of the corn straw.

[0046] As Figure 2 、 Figure 3 and Figure 4As shown, the installation unit 6 includes installation columns 30. On the upper end faces of the fixed steel frame 1, the extension frame 4, and the installation frame 3, a plurality of installation columns 30 are fixedly arranged in an equidistant manner from front to back with their axes vertical. A plurality of installation cylinders 31 arranged in an equidistant manner from front to back are fixedly sleeved through the horizontal sections of the placement racks 5. The inner diameter of the installation cylinder 31 is the same as the diameter of the installation column 30.

[0047] As Figure 3 and Figure 4 shown, a locking frame 32 is jointly arranged between the horizontal sections of two adjacent placement racks 5. The locking frame 32 is Z-shaped. A rectangular placement groove 320 is formed on the lower end face of the horizontal section of the placement rack 5. One horizontal section of the locking frame 32 is located above the horizontal section of the adjacent placement rack 5 on the left, and the other horizontal section is located in the placement groove 320 on the horizontal section of the adjacent placement rack 5 on the right. A waist-shaped avoidance groove 321 is formed on the upper horizontal section of the locking frame 32. Installation grooves 322 are formed on both horizontal sections of the locking frame 32. A threaded column 323 with a vertical axis is fixedly arranged on the upper end face of the installation frame 3. A nut 324 is threadedly installed on the threaded column 323.

[0048] As Figure 2 shown, support frames 33 are fixedly arranged on the rear end face of the fixed steel frame 1 and the front end face of the installation frame 3. Support grooves are formed in the support frames 33. Support plates 330 inserted into the support grooves are inserted and installed on the rear end face of the last placement rack 5 and the front end face of the foremost placement rack 5.

[0049] During operation, before the harvesting operation, the corresponding number of placement racks 5 and the specified number of extension frames 4 are installed on the installation rod according to the required harvesting stations, and the extension frames 4 are located between the fixed steel frame 1 and the installation frame 3. The specific installation process is as follows: Workers cooperate with external lifting equipment to hoist and place the placement racks 5 on the fixed steel frame 1 in sequence, and make the installation columns 30 at the corresponding positions penetrate through the installation cylinders 31 on the placement racks 5 to complete the preliminary assembly of the placement racks 5. Secondly, during this process, the way of inserting and matching the corresponding installation columns 30 with different installation cylinders 31 on the placement racks 5 is adjusted to adjust the distance between two adjacent placement racks 5, so as to adjust the distance between the corresponding auxiliary plate one 720 and the auxiliary plate two 721, ensuring that they can have a sufficient limiting and holding effect on the corn straws.

[0050] And during the above placement process, when the placement rack 5 is placed on the steel frame, the upper horizontal section of the corresponding locking rack 32 presses the corresponding rear placement rack 5, and the lower horizontal section is located in the placement groove 320 of the front placement rack 5, and the corresponding mounting column 30 penetrates through the corresponding mounting groove 322, completing the locking installation of the locking rack 32 and the placement rack 5. Finally, the worker tightens the nut 324 onto the threaded column 323 to complete the locking of all the placement racks 5 and the locking racks 32, the locking of the fixed steel frame 1, the extension frame 4, and the mounting frame 3. Through the above installation method, all the placement racks 5 are locked and integrated with each other, improving the stability of the placement rack 5 after being locked. At the same time, the above installation method improves the convenience during the installation process, and is also convenient for replacing a certain placement rack 5 and the corresponding harvesting station during subsequent maintenance, improving the convenience of the device and facilitating adaptation to the needs of different numbers of harvesting stations.

[0051] During the assembly of the placement rack 5, the corresponding two support plates 330 are inserted into the corresponding support grooves to support all the support frames 33, improving the stability of the placement rack 5 during the mobile harvesting process.

[0052] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, the drive unit 8 includes a drive shaft 80. The upper end surface of the inclined section of the placement rack 5 is rotatably provided with a drive shaft 80 whose axis is parallel to the axis of the rotating shaft 73. A first gear 800 is fixedly sleeved on both the drive shaft 80 and the front rotating shaft 73 on the placement rack 5. Adjacent two gears mesh with each other. A chain drive connection is provided between the drive shaft 80 and the rear rotating shaft 73 on the placement rack 5 through a sprocket 730. The lower end surface of the horizontal section of the placement rack 5 is rotatably provided with a horizontal shaft 801 through a horizontal frame. A bevel gear 802 is fixedly provided on both the lower end of the front rotating shaft 73 on the placement rack 5 and the horizontal shaft 801. Adjacent two bevel gears 802 mesh with each other.

[0053] As Figure 2 and Figure 5 shown, the drive unit 8 further includes a drive sprocket 81. A drive sprocket 81 is fixedly provided at the right end of all the horizontal shafts 801. All the drive sprockets 81 are connected by a drive chain. The lower end surface of the fixed steel frame 1 is slid up and down through a second hydraulic cylinder to be provided with a lifting plate 810. The right end of the lifting plate 810 is rotatably provided with an auxiliary sprocket 811 for tightening the drive chain.

[0054] During operation, after installing the placement rack 5, the corresponding driving sprockets 81 and auxiliary sprockets 811 on all placement racks 5 are in the same plane in the front-back direction. Therefore, when the placement rack 5 is locked by the installation unit 6, all driving sprockets 81 are located at the specified reference positions. Then, the driving sprockets 81 are installed on the driving sprockets 81 and auxiliary sprockets 811. At the same time, the second hydraulic cylinder works to drive the lifting plate 810 to drive the auxiliary sprocket 811 to move, so that the driving chain is always kept taut.

[0055] During the harvesting operation, the external motor works to drive one of the driving sprockets 81 to rotate. Through the transmission of the driving chain, the remaining driving sprockets 81 rotate synchronously. The driving sprocket 81 drives the corresponding horizontal shaft 801 to rotate synchronously. The horizontal shaft 801 drives the bevel gear 802 thereon to rotate synchronously. Through the meshing between the corresponding two bevel gears 802, the rotating shaft 73 rotates synchronously. The rotating shaft 73 drives the first gear 800 thereon to rotate synchronously. Through the meshing transmission between two adjacent first gears 800, the transmission shaft 80 rotates. Through the chain transmission of the sprocket 730, the other rotating shaft 73 on the same placement rack 5 also rotates, and the two rotating shafts 73 on the same placement rack 5 rotate in opposite directions. At the same time, the drive is transmitted to the cutting knife 70 and the auger unit 71, so that the cutting knife 70 performs a cutting action and the auger unit 71 drives the corn straw to move in a specified direction.

[0056] As Figure 1 shown, a guiding cover 9 is fixedly arranged on the upper end surface of the inclined section of the placement rack 5.

[0057] During operation, the movement direction of the corn straw is guided by the provided guiding cover 9 to guide the feeding process, and at the same time, the guiding cover 9 plays a protective role for the driving unit 8.

[0058] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0059] In addition, the terms "first", "second", "No. 1", and "No. 2" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", "No. 1", or "No. 2" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0060] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and defined, the terms "arranged", "connected", "installed", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements.
