[0047] In order to make the above-mentioned objectives, features and advantages of the present application more apparent and comprehensible, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0048] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be appreciated that the present application can be practiced in a variety of ways beyond the specific details set forth herein, having regard to the content of the detailed description and the appended claims, the full scope of the application being set forth only by the claims.

[0049] Second, the "one embodiment" or "an embodiment" appearing in the specification herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. The "in a preferred embodiment" appearing in different places in the specification herein does not mean the same embodiment, nor does it mean an embodiment that is separate from or exclusive to other embodiments.

[0050] Third, the present application is described in detail in conjunction with the schematic drawings, and in the detailed description of the embodiments of the present application, the sectional view of the device structure is partially enlarged without the general proportion for the convenience of illustration, and the schematic drawings are only examples, which should not limit the scope of protection of the present application. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0051] Please refer to Figure 1 As shown in the drawings, the present application provides a cotton harvester, which comprises: a cotton harvester 1 for picking cotton, a pea planter 2 is pulled behind the cotton harvester 1 through a hitch mechanism 7, and a control mechanism 10 for equipment control adjustment is installed on the pea planter 2; wherein the pea planter 2 comprises a trimming mechanism 3 and a furrow mechanism 4, and a seeding mechanism 5 and a soil covering mechanism 6, wherein the trimming mechanism 3 comprises a transverse trimming structure 8 and a longitudinal trimming structure 9; the furrow mechanism 4 comprises a vehicle body two 401 and a coulter 406 movably installed on the vehicle body two 401; the seeding mechanism 5 comprises a vehicle body three 501, a material tank 502 is installed on the vehicle body three 501, a receiving hopper 504 is arranged below the material tank 502, and a seeding wheel 503 is rotatably arranged between the material tank 502 and the receiving hopper 504; the soil covering mechanism 6 comprises a vehicle body four 601 and a soil covering sheet 606 movably installed on the vehicle body four 601; the transverse trimming structure 8 comprises a transversely rotatable transverse saw blade 802, and the longitudinal trimming structure 9 comprises a longitudinally rotatable longitudinal saw blade 902.

[0052] In this embodiment, in the cotton-pea intercropping operation where peas are sown simultaneously while cotton is being harvested, a cotton harvester 1 moves forward to harvest the cotton, and then a pea planter 2 is pulled behind to sow the pea seeds. When sowing peas using the pea planter 2, the cotton stalks are first trimmed by a trimming mechanism 3 to provide good space for sowing and subsequent pea growth. After trimming, the furrow mechanism 4 opens furrows in the soil to facilitate the burying of pea seeds in the soil for growth. After opening the furrows, the sowing mechanism 5 sows the pea seeds in the furrows. After sowing the seeds, the soil generated from the furrows is gathered and backfilled into the furrows by a subsequent soil-sealing mechanism 6 to cover the pea seeds with soil, allowing the pea seeds to take root and germinate in the soil. This completes a series of planting operations for pea seeds.

[0053] Using a pea planter 2 to sow peas between rows of cotton vines maximizes land use. Furthermore, using cotton stalks as supports for the pea vines reduces the need for scaffolding and lowers labor costs.

[0054] In a preferred embodiment, please refer to Figure 3 and Figure 4 As shown, the transverse trimming structure 8 also includes multiple sets of rotating shafts 801 that are longitudinally rotatably mounted on the vehicle body 301. Each rotating shaft 801 has a transverse saw blade 802 mounted at its lower end, and a drive motor 803 is connected to the upper end of the rotating shaft 801. The multiple sets of transverse saw blades 802 are arranged close to each other but do not contact each other.

[0055] In this embodiment, when the pea planter 2 is pulled forward by the cotton harvester 1, the vehicle body 301 will move forward along with the transverse trimming structure 8. The drive motor 803 in the transverse trimming structure 8 drives the rotation of the shaft 801, which in turn drives the high-speed rotation of the transverse saw blade 802. The transverse saw blade 802 trims off the cotton stalks that are higher than the transverse saw blade 802, so that the cotton stalks, as supports, are at a relatively uniform height, which is convenient for subsequent management. Furthermore, the arrangement of multiple transverse saw blades 802 that are close to each other but do not touch means that the distance between the edges of every two transverse saw blades 802 is relatively close, which can cut the stalks and avoid the gap between two transverse saw blades 802 being too large, which would cause missed cuts and result in incomplete cleaning.

[0056] Secondly, please refer to again Figure 3 and Figure 5As shown, the longitudinal trimming structure 9 includes a second rotating shaft 901 that is laterally rotatably disposed below the vehicle body 301. The second rotating shaft 901 is equipped with multiple sets of longitudinal saw blades 902, and the middle section of the second rotating shaft 901 is rotatably connected to the support frame 903. The second rotating shaft 901 is connected to a second drive motor 904 through a bevel gear set 905, and the second drive motor 904 is fixedly connected to the support frame 903. The upper end of the support frame 903 is connected to a first telescopic rod 906, and the other end of the first telescopic rod 906 is fixedly connected to the vehicle body 301. A guide rod 907 passes through the inner side of the support frame 903, and the upper end of the guide rod 907 is fixedly connected to the vehicle body 301.

[0057] The longitudinal trimming structure 9 is installed at a relatively rearward position relative to the transverse trimming structure 8 in the direction of travel of the vehicle body 301. The longitudinal trimming structure 9 and the transverse trimming structure 8 work together to trim the cotton stalks without interfering with each other. The longitudinal saw blade 902 of the longitudinal trimming structure 9 travels along both sides of each row of cotton stalks, trimming excess stalks on both sides. During trimming, the longitudinal trimming structure 9 is moved along by the movement of the vehicle body 301. Driven by the second drive motor 904 and the rotation of the bevel gear set 905, the second shaft 901 rotates. The rotation of 1 drives the high-speed rotation of the longitudinal saw blade 902, which trims the straw. During trimming, in order to ensure that straw of different heights on both sides can be trimmed, the longitudinal saw blade 902 connected to the support frame 903 can be adjusted up and down by the extension and retraction of the telescopic rod 906. By adjusting the longitudinal saw blade 902, straw of different heights can be trimmed. When the support frame 903 moves up and down, it will move up and down along the guide rod 907. The setting of the guide rod 907 makes the adjustment of the device more stable.

[0058] The longitudinal saw blades 902 are provided in multiple sets, and each set of longitudinal saw blades 902 is provided with two saw blades. The distance between the two adjacent saw blades of each set of longitudinal saw blades 902 is consistent with the width of the furrow between two rows of cotton, and the distance between the two saw blades of each set of longitudinal saw blades 902 is consistent with the main width of each row of cotton.

[0059] like Figure 5 As shown in the figure, the longitudinal saw blade 902 installed on the rotating shaft 901 is used to trim two rows of cotton stalks at the same time. The distance between the two sets of saw blades is the width of the furrow between the two rows of cotton, and the two saw blades in each set of longitudinal saw blades 902 are exactly the width of each row of cotton that needs to be trimmed, which can trim the excess stalks of cotton.

[0060] In a preferred embodiment, please refer to Figure 6As shown, the furrow mechanism 4 further comprises a guide groove one 402 arranged on the vehicle body two 401, an adjusting block one 403 is arranged in the guide groove one 402 and slides up and down, the upper end of the adjusting block one 403 is connected with an extension rod two 404, the upper end of the extension rod two 404 is fixedly connected with the top end of the guide groove one 402, the lower end of the adjusting block one 403 is connected with a fixed rod one 405, the fixed rod one 405 is installed with a plough 406, and the moving wheels 407 are installed below the two sides of the vehicle body two 401;

[0061] In this embodiment, it is necessary to open a trench between the two cotton ridges, so as to facilitate the seed to be put in, and then to cover the soil, so as to facilitate the seed to grow in the soil. The furrow mechanism 4 can open the trench. When the trench is opened, the pea planter 2 is dragged forward by the cotton harvester 1, and the vehicle body two 401 is driven to move forward. When moving forward, the extension rod two 404 is extended to drive the adjusting block one 403 to move downward along the guide groove one 402, and the adjusting block one 403 drives the plough 406 installed on the fixed rod one 405 to move downward until the plough 406 contacts the ground and extends into the soil. Through the forward movement of the plough 406, the soil can be washed away, so as to achieve the purpose of opening the trench, and the depth of the trench can be determined according to the depth of the extension rod two 404 driving the plough 406 to extend downward into the soil. At the same time, when the soil is not opened, the extension rod two 404 can be controlled to drive the plough 406 to move upward and leave the contact with the ground.

[0062] Secondly, please refer again to Figure 7 As shown, a plurality of groups of concave grooves for containing pea seeds are evenly arranged on the arc surface of the seeding wheel 503, one end of the seeding wheel 503 is connected with a driving motor three 505, the lower end of the material hopper 504 is connected with a discharging pipe 506, and the discharging port of the discharging pipe 506 is on the same straight line with the plough 406 in the forward direction of the pea planter 2;

[0063] After the trench is dug, the seeds are scattered into the trench at a certain planting distance. When the seeds are scattered, the seeds are thrown into the trough 502, and the seeding wheel 503 is uniformly rotated by the driving motor three 505. When the groove in the seeding wheel 503 is in the trough 502, the seeds will fall into the groove. Then, when the groove in the seeding wheel 503 is in the receiving hopper 504, the seeds in the groove will be poured into the receiving hopper 504, and then fall into the dug trench along the discharge pipe 506, completing the seeding of the seeds. The spacing of the seeds can be determined according to the speed of the pea planter 2 and the rotation speed of the seeding wheel 503 driven by the driving motor three 505. When the spacing of the seeds to be planted is small, the rotation speed of the seeding wheel 503 driven by the driving motor three 505 can be fast. When the spacing of the seeds to be planted is large, the rotation speed of the seeding wheel 503 driven by the driving motor three 505 can be slow, provided that the speed of the pea planter 2 does not change.

[0064] Secondly, please refer to Figure 8 The vehicle body four 601 is provided with a guide groove two 602, and the inside of the guide groove two 602 is slidably provided with an adjusting block two 603. The upper end of the adjusting block two 603 is connected with an extension rod three 604, and the upper end of the extension rod three 604 is fixed on the guide groove two 602. The lower end of the adjusting block two 603 is provided with a fixed rod two 605, and the fixed rod two 605 is provided with a soil sealing piece 606.

[0065] The above structure is used after the seeds are planted. The soil on both sides of the trench is gathered inward and backfilled into the trench where the seeds are planted, covering the seeds and facilitating the growth of the seeds in the soil. When the soil is backfilled, the soil sealing mechanism 6 is driven forward by the forward movement of the vehicle body four 601, the soil on both sides is gathered inward by the soil sealing piece 606, and the soil is backfilled into the trench. The extension rod three 604 is extended to drive the adjusting block two 603 to move downward along the guide groove two 602, and the soil sealing piece 606 installed by the fixed rod two 605 is driven to move downward and contact the ground, so that the soil sealing piece 606 can touch the soil on both sides of the trench, and then the soil is backfilled into the trench by the soil sealing piece 606.

[0066] In a preferred embodiment, please refer to Figure 9 The soil sealing piece 606 is a reverse eight-shaped mechanism in the forward direction of the pea planter 2, and the lower end of the soil sealing piece 606 is provided with a soil leakage groove 6061.

[0067] In this embodiment, the soil generated during trenching can be introduced inward by the reverse eight-shaped structure of the soil sealing piece 606, and then leaked out through the soil leakage groove 6061, all accumulated in the trench, achieving backfilling of the soil.

[0068] Secondly, please refer toFigure 2 The towing mechanism 7 comprises a bracket 701 mounted at the front end of the pea planter 2 and a connecting seat 702 mounted at the tail end of the cotton harvester 1, and the connecting seat 702 and the bracket 701 are connected through the insertion of the pin 703;

[0069] The docking between the pea planter 2 and the cotton harvester 1 through the towing mechanism 7 can make the use of the device more flexible. When connecting, the alignment of the connecting seat 702 and the bracket 701 is followed by the insertion of the pin 703 to complete the docking. When disconnecting, the pin 703 is pulled out to complete the disconnection of the connecting seat 702 and the bracket 701

[0070] Thirdly, as shown in the figure, Figure 10 The car body one 301 and the car body two 401 and the car body three 501 and the car body four 601 are in a split structure and are connected at the head and tail through bolts. The driving structure between the control mechanism 10 and the pruning mechanism 3 and the furrow mechanism 4 and the seeding mechanism 5 and the soil sealing mechanism 6 is connected through wires.

[0071] The split structure of the car body one 301 and the car body two 401 and the car body three 501 and the car body four 601 can facilitate the disassembly and assembly of the pea planter 2, making the movement more convenient. Only one set of moving wheels 407 needs to be installed on any one car body to make the device move. The control mechanism 10 is used to control each driving structure in the pruning mechanism 3 and the furrow mechanism 4 and the seeding mechanism 5 and the soil sealing mechanism 6, which facilitates the normal use of each driving structure, such as the start and stop of the driving motor one 803 in the pruning mechanism 3 and the extension control of the extension rod one 906, etc., so that the device can complete a series of operations of seeding.

[0072] The application also provides a method for planting peas based on cotton stalks, which is applied to the above-mentioned cotton harvester and comprises the following steps:

[0073] Step 1, the cotton harvester 1 walks and picks cotton;

[0074] Step 2, the cotton harvester 1 pulls the pea planter 2 to walk synchronously, prunes the cotton stalks through the pruning mechanism 3, and plows through the furrow mechanism 4;

[0075] Step 3, the seeding mechanism 5 spreads the pea seeds into the furrow

[0076] Step 4, the soil sealing mechanism 6 gathers the soil produced by the furrow to backfill it into the groove, realizing the covering of the pea seeds.

[0077] The working principle of the present application is that in the cotton and pea interplanting in which the peas are sowed simultaneously when picking the cotton, the cotton harvester 1 walks in front and picks the cotton, and then the pea planter 2 towed by the rear sows the pea seeds, in the operation of sowing the peas by the pea planter 2, first, the cotton stalks are trimmed to provide a good space for sowing and later growth of the peas, after the trimming, the land is ploughed by the furrow mechanism 4 to facilitate the growth of the pea seeds in the soil, after the land is ploughed, the pea seeds are sowed in the furrow by the sowing mechanism 5, after the seeds are sowed, the soil produced by the ploughing is gathered and backfilled into the furrow by the subsequent soil sealing mechanism 6 to cover the pea seeds, so that the pea seeds germinate and grow in the soil, and thus a series of sowing operations of the pea seeds are completed.

[0078] The above is only the preferred embodiment of the present application, it should be pointed out that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, these improvements and refinements should also be considered as the protection scope of the present application.
