Description

Technical Field

[0001] The invention relates to the technical field of crop harvesting, in particular to a hydraulic self-propelled corn seed and stalk combine harvester. Background Art

[0002] Corn seed and stalk combine harvester is a kind of agricultural machinery specially designed for harvesting corn kernels and corn stalks at the same time. This machine combines the functions of traditional harvesting, threshing and stalk processing, greatly improving the efficiency of corn harvesting and reducing the demand for labor.

[0003] During operation, the current corn seed stalk combine harvester will first cut off the corn stalks together with the roots, and then transport the corn stalks to the equipment through the auger unit and the conveyor chain. In this process, the cooperation of the above two makes the stalks move inward in the left and right directions while the stalks move downward. The set cutting knife cuts the stalks into sections for subsequent processing. Finally, the corn is separated from the stalks 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: in the process of transporting corn stalks and cutting the stalks, the corn stalks need to be kept in a vertical downward state as much as possible during transportation to ensure that the corn can fall into the designated area after the stalks are cut multiple times by the cutting knife. The state of the stalks during transportation depends on their initial tilt state. Therefore, the current cutting method can only harvest vertically oriented stalks.

[0035] like Figure 1 and Figure 2 As shown, a hydraulic self-propelled corn stalk combine harvester comprises:

[0036] A fixed steel frame 1 is provided with a mobile unit 2 on the right side of the fixed steel frame 1, the mobile unit 2 includes an existing external mobile wheel, the mobile unit 2 and the fixed steel frame 1 are provided with a corn peeling device and a corn threshing device (not shown in the figure) for subsequent processing of harvested corn, the front end surface of the fixed steel frame 1 is provided with a mounting frame 3 which is slidable back and forth through two mounting rods distributed on the left and right, and an expansion frame 4 is provided between the fixed steel frame 1 and the mounting frame 3.

[0037] like Figure 1 and Figure 2As shown, the fixed steel frame 1, the mounting frame 3 and the expansion frame 4 are jointly provided with a plurality of placement frames 5 which are arranged equidistantly from front to back, and the placement frames 5 are successively composed of an inclined section and a horizontal section from left to right, and the inclined section is inclined upward from left to right, and all the placement frames 5 and the fixed steel frame 1, the mounting frame 3 and the expansion frame 4 are jointly provided with an installation unit 6, and all the placement frames 5 are successively installed and locked from front to back through the installation unit 6.

[0038] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, a harvesting mechanism 7 is commonly provided on all the placement racks 5, and two adjacent placement racks 5 together form a harvesting station, the harvesting mechanism 7 includes a cutting knife 70, the lower end surface of the placement rack 5 is rotatably provided with a cutting knife 70 and a swirling unit 71 whose axis extends along the length direction of the inclined section of the corresponding placement rack 5, the lower end surface of the inclined section of the placement rack 5 is provided with two front-to-rear distributed conveying chains 72, and the circumferential surfaces of the two conveying chains 72 on the same placement rack 5 are respectively provided with an auxiliary plate 1 720 and an auxiliary plate 2 721, the auxiliary plate 1 720 and the auxiliary plate 2 721 are both V-shaped, and the auxiliary plate 1 720 and the auxiliary plate 2 721 on the two adjacent conveying chains 72 on the adjacent placement racks 5 cooperate, and a driving unit 8 is provided on the fixed steel frame 1.

[0039] It should be noted that the driving unit 8 drives the conveying chain 72 to transport the corn stalks, and drives the cutting knife 70 and the auger unit 71 to operate synchronously, that is, the auger unit 71 drives the corn stalks to move downward, and the cutting knife 70 cuts the stalks into multiple sections in sequence. The movement route of the corn stalks is shown in FIG. Figure 7 , and secondly, the operation methods of these two parts are both external existing operation technologies.

[0040] During operation, first, the required additional expansion rack 4 is installed between the mounting rack 3 and the fixed steel frame 1 according to the required harvesting station, and then the required number of placement racks 5 is selected according to the required number of harvesting stations, and all the placement racks 5 and the harvesting mechanisms 7 thereon are integrally locked through the mounting unit 6, and the conveying chain 72 in the harvesting mechanism 7 is connected to the driving unit 8, and the moving unit 2 works to make the fixed steel frame 1, the corn peeling device and the corn threshing device move left synchronously. During the left movement, the driving unit 8 works to make the two conveying chains 72 on the same placement rack 5 rotate synchronously and in opposite directions, and the two adjacent conveying chains 72 on the adjacent placement racks 5 cooperate with each other, and the auxiliary plates 1 720 and 2 721 on the two conveying chains 72 close together and cooperate with each other, while driving the corn stalks to move right, the corn stalks are kept in a vertical direction during the right movement, and at the same time, the stirring unit drives the corn stalks to move downward, and the cutting knife 70 rotates to cut the stalks, and finally the stalks are cut section by section, and the corn is recovered from the top of the fixed steel frame 1 to the corn peeling device and the corn threshing device for the next processing operation.

[0041] like Figure 1 , Figure 8 and Fig. 9 As shown, the harvesting mechanism 7 also includes a rotating shaft 73, and four rotating shafts 73 arranged in a matrix are rotatably installed on the inclined section of the placement frame 5. A sprocket 730 is fixedly sleeved on the rotating shaft 73, and the conveying chain 72 is sleeved on the corresponding two sprockets 730. The circumferential surface of the conveying chain 72 is fixedly provided with a plurality of fixed blocks 731 distributed along its length direction, and the fixed block 731 is provided with a connecting column 732 for sliding back and forth away from the end surface of the corresponding conveying chain 72. The auxiliary plate 1 720 and the auxiliary plate 2 721 are fixedly provided on the corresponding connecting column 732, and the vertical thickness of the auxiliary plate 1 720 is greater than the vertical thickness of the auxiliary plate 2 721. Both sections of the auxiliary plate 1 720 are provided with a matching groove 733 that matches the corresponding auxiliary plate 2 721.

[0042] like Figure 8 and Fig. 9 As shown, taking the adjacent auxiliary plate 1 720 and the auxiliary plate 2 721 on the adjacent placement rack 5 as an example, the left side sections of the auxiliary plate 1 720 and the auxiliary plate 2 721 away from the end faces of the corresponding fixed blocks 731 are fixedly provided with arc strips 734, and the inner arc surface of the arc strip 734 faces the corresponding auxiliary plate 1 720 or the auxiliary plate 2 721.

[0043] like Figure 8 and Fig. 9As shown, a hydraulic cylinder 735 with an axis extending from front to rear and corresponding one to one with the conveying chain 72 is fixedly provided on the lower end surface of the placement rack 5, and a push plate 736 is fixedly provided on the telescopic end of the hydraulic cylinder 735. The push plate 736 is composed of an inclined section and a transverse horizontal section from left to right, and its inclined section is inclined from left to right in a direction away from the corresponding hydraulic cylinder 735. The upper end surface of the fixed block 731 slides back and forth and is penetrated by a fixed bar 737, which is fixedly connected to the corresponding connecting column 732.

[0044] During operation, after the placement rack 5 is fixedly installed, the driving unit 8 works to rotate the rotating shaft 73, and the rotating shaft 73 drives the corresponding conveying chain 72 to rotate synchronously through the sprocket 730, and the rear conveying chain 72 of the two adjacent conveying chains 72 on the adjacent placement racks 5 rotates counterclockwise, and the front conveying chain 72 rotates clockwise. During the rotation of the conveying chain 72, the fixed block 731, the connecting column 732, the auxiliary plate 1 720 and the auxiliary plate 2 721 thereon are driven to move synchronously. In the process of the moving unit 2 gradually moving to the left, the auxiliary plate 1 720 or the auxiliary plate 2 721 on the conveying chain 72 gradually rotates to between the two adjacent placement racks 5. During the rotation process, the arc strips 734 on the auxiliary plate 1 720 and the auxiliary plate 2 721 assist in catching The corn stalks are caught to facilitate the movement of the stalks to between the corresponding auxiliary plate 1 720 and the auxiliary plate 2 721. As the conveyor chain 72 gradually moves, the corresponding auxiliary plate 1 720 and the auxiliary plate 2 721 gradually close together and finally press against the corn stalks, that is, the two begin to embrace the corn stalks from the lower end portion of the corn stalks. Through the above-mentioned method and the mutual cooperation between the agitator unit 71, the corn stalks gradually move to the right and maintain a vertical orientation, which is convenient for harvesting the inclined corn stalks. At the same time, the corn stalks are kept in a vertical orientation during the cutting process of the corn stalks by the cutting knife 70, so as to avoid the corn stalks from tipping over during the movement, causing the corn to deviate from the specified route and unable to be transferred to the right side of the fixed steel frame 1 and unable to enter the corn peeling equipment and corn threshing equipment.

[0045] During the above operation process, the hydraulic cylinder 735 works so that its telescopic end drives the push plate 736 to move forward and backward. The push plate 736 stops moving after moving to the specified position. When the conveyor chain 72 drives the fixed block 731 to move, the fixed bar 737 first contacts the inclined section of the push plate 736, and finally moves to the end face of the push plate 736 away from the corresponding hydraulic cylinder 735. Therefore, the distance between the corresponding two fixed bars 737 is controlled by the above method, that is, the distance between the auxiliary plate 1 720 and the auxiliary plate 2 721 that need to be coordinated is controlled, to ensure that the auxiliary plate 1 720 and the auxiliary plate 2 721 can tightly embrace the corn stalks and ensure the vertical orientation of the corn stalks.

[0046] like Figure 2 , Figure 3 and Figure 4As shown, the installation unit 6 includes an installation column 30, and the upper end surfaces of the fixed steel frame 1, the expansion frame 4 and the installation frame 3 are jointly fixed with a plurality of installation columns 30 which are arranged equidistantly from front to back and have vertical axes, and the horizontal section of the placement frame 5 is fixed with a plurality of installation cylinders 31 which are arranged equidistantly from front to back, and the inner diameter of the installation cylinder 31 is the same as the diameter of the installation column 30.

[0047] like Figure 3 and Figure 4 As shown, a locking frame 32 is commonly provided between the horizontal sections of two adjacent placement frames 5, the locking frame 32 is Z-shaped, and a rectangular placement groove 320 is provided on the lower end surface of the horizontal section of the placement frame 5, one of the horizontal sections of the locking frame 32 is located above the horizontal section of the adjacent placement frame 5 on the left, and the other horizontal section is located in the placement groove 320 on the adjacent horizontal section on the right, a waist-shaped avoidance groove 321 is provided on the upper horizontal section of the locking frame 32, and installation grooves 322 are provided on the two horizontal sections of the locking frame 32, and a threaded column 323 with a vertical axis is fixedly provided on the upper end surface of the installation frame 3, and a nut 324 is threadedly installed on the threaded column 323.

[0048] like Figure 2 As shown, the rear end face of the fixed steel frame 1 and the front end face of the mounting frame 3 are both fixedly provided with a support frame 33, a support groove is opened on the support frame 33, and the rear end face of the rearmost placement frame 5 and the front end face of the frontmost placement frame 5 are both plugged and installed with a support plate 330 inserted into the support groove.

[0049] During operation, before harvesting, a corresponding number of placement racks 5 and a specified number of expansion racks 4 are installed on the mounting rod according to the required harvesting stations, and the expansion racks 4 are located between the fixed steel frame 1 and the mounting rack 3. The specific installation process is as follows: manually cooperate with external lifting equipment to lift and place the placement racks 5 on the fixed steel frame 1 in turn, and make the mounting columns 30 at the corresponding positions pass through the mounting tubes 31 on the placement racks 5 to complete the preliminary assembly of the placement racks 5. Secondly, in this process, the corresponding mounting columns 30 are adjusted to be plugged in and matched with different mounting tubes 31 on the placement racks 5, and the distance between two adjacent placement racks 5 is adjusted, thereby adjusting the distance between the corresponding auxiliary plate 1 720 and the auxiliary plate 2 721 to ensure that the two can have sufficient limiting and holding effects on the corn stalks.

[0050] And in the above-mentioned placement process, when the placement rack 5 is placed on the steel frame, the upper horizontal section of the corresponding locking rack 32 is pressed against the corresponding rear placement rack 5, and the lower horizontal section is located in the placement groove 320 on the front placement rack 5, and the corresponding installation column 30 passes through the corresponding installation groove 322 to complete the locking installation of the locking rack 32 and the placement rack 5. Finally, the nut 324 is manually tightened onto the threaded column 323 to complete the locking of all placement racks 5 and the locking rack 32, and the locking between the fixed steel frame 1, the expansion rack 4 and the installation rack 3. Through the above-mentioned installation method, all placement racks 5 are locked with each other and locked as an integrated whole, which improves the stability of the placement rack 5 after being locked. At the same time, the above-mentioned installation method improves the convenience of the installation process. At the same time, in the subsequent maintenance process, it is convenient to replace a certain placement rack 5 and the corresponding harvesting station, thereby improving the convenience of the device and facilitating adaptation to the needs of different numbers of harvesting stations.

[0051] During the process of assembling the placement rack 5, the corresponding two support plates 330 are inserted into the corresponding support grooves, thereby supporting all the support racks 33 and improving the stability of the placement rack 5 during the mobile harvesting process.

[0052] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the driving unit 8 includes a transmission shaft 80, and the upper end surface of the inclined section of the placement rack 5 is rotatably provided with a transmission shaft 80 whose axis is parallel to the axis of the rotating shaft 73. The transmission shaft 80 and the front rotating shaft 73 on the placement rack 5 are both fixedly sleeved with a gear 800, and two adjacent gears are meshed with each other. The transmission shaft 80 and the rear rotating shaft 73 on the placement rack 5 are connected by a chain transmission of a sprocket 730. The lower end surface of the horizontal section of the placement rack 5 is rotatably provided with a horizontal shaft 801, and a bevel gear 802 is fixedly provided on the lower end of the rotating shaft 73 on the front side of the placement rack 5 and the horizontal shaft 801, and two adjacent bevel gears 802 are meshed.

[0053] like Figure 2 and Figure 5 As shown, the driving unit 8 also includes a driving sprocket 81, and the right ends of all the horizontal axes 801 are fixedly provided with driving sprockets 81, and all the driving sprockets 81 are connected by driving chains. The lower end surface of the fixed steel frame 1 is provided with a lifting plate 810 that slides up and down through hydraulic cylinder 2, and the right end of the lifting plate 810 is rotatably provided with an auxiliary sprocket 811 for tightening the driving chain.

[0054] During operation, after the placement rack 5 is installed, the corresponding drive sprockets 81 and the auxiliary sprockets 811 on all the placement racks 5 are in the same plane in the front-to-back direction. Therefore, the placement rack 5 is locked by the installation unit 6 while all the drive sprockets 81 are located at the specified reference position. Then, the drive sprocket 81 is installed on the drive sprocket 81 and the auxiliary sprocket 811. At the same time, the hydraulic cylinder 2 works to make the lifting plate 810 drive the auxiliary sprocket 811 to move, so that the drive chain is always kept taut.

[0055] When harvesting, the external motor drives one of the drive sprockets 81 to rotate, and the remaining drive sprockets 81 rotate synchronously through the transmission of the drive chain. The drive sprocket 81 drives the corresponding horizontal shaft 801 to rotate synchronously, and the horizontal shaft 801 drives the bevel gear 802 thereon to rotate synchronously. The engagement between the corresponding two bevel gears 802 makes the rotating shaft 73 rotate synchronously, and the rotating shaft 73 drives the gear 1 800 thereon to rotate synchronously. The meshing transmission between the two adjacent gears 1 800 makes the transmission shaft 80 rotate, and the chain transmission of the sprocket 730 makes the other rotating shaft 73 on the same placement rack 5 also rotate, 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 cutting action and the auger unit 71 drives the corn stalks to move in the specified direction.

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

[0057] During operation, the guide cover 9 is provided to guide the moving direction of the corn stalks and guide the feeding process. Meanwhile, the guide cover 9 protects the driving unit 8 .
