Description

Technical Field

[0001] This invention relates to the field of agricultural planting technology, and in particular to an operation method for rotary tillage and sowing using a combination of wide and narrow strips. Background Technology

[0002] A new sowing operation mode has emerged, employing a combination of wide-width and narrow-width agricultural machinery. The wide-width and narrow-width machines operate in a staggered manner to sow two different crops. The narrow-width machine operates in area A, and the wide-width machine operates in area B. The wide-width and narrow-width machines are respectively a furrowing rotary tiller and a rotary tiller, differing only in their operating width. In existing technologies, the specific operation method using a ditching rotary tiller and rotary tiller is as follows: first, a narrow-width agricultural machine is used for navigation to complete the loosening and sowing operation in work area A; before working in work area B, a ditching rotary tiller with the corresponding ditching width is selected according to the operation requirements to dig furrows in the field, and then the machine is used for navigation until the sowing in work area B of the farmland is completed. When moving to the next farmland, if the required ditching width for wide-width operation is different, a new wide-width agricultural machine needs to be equipped for navigation. Although it can achieve the combination of wide and narrow width sowing, it requires the use of multiple wide-width agricultural machines with different ditching width specifications for navigation, which is costly.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0041] Example 1

[0042] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a method for rotary tillage and seeding with a combination of wide and narrow furrows, which can adapt to operations with different furrow width requirements and reduce the cost of machinery.

[0043] A method for rotary tillage and seeding using a combination of wide and narrow widths includes a wide-width furrowing rotary tillage seeder and a narrow-width rotary tillage seeder 7000. The wide-width furrowing rotary tillage seeder includes a wide-width furrowing rotary tillage seeder frame 800, with a furrowing assembly 100 connected to the front end of the frame 800. The furrowing assembly 100 includes a first furrowing plow 102 and a second furrowing plow 101 slidably connected to the frame 800. The opposite sides of the first furrowing plow 102 and the second furrowing plow 101 can be joined together, and their bottom sides are flush. The lower part of the first furrowing plow 102 has a sliding groove 102d. A furrowing plow 101 is fixed to one end relative to the first furrowing plow 102 with a furrowing width adjustment part 101d. The furrowing width adjustment part 101d can slide along the sliding trough 102d. When the positions of the first furrowing plow 102 and the second furrowing plow 101 are adjusted and the opposite sides of the first furrowing plow 102 and the second furrowing plow 101 are not in contact, there is a gap between the lower side of the furrowing width adjustment part 101d and the bottom of the second furrowing plow 101. A wide-width seed box 300 is fixedly connected to the upper rear part of the wide-width furrowing rotary tillage seeder frame 800. The lower side of the wide-width seed box 300 is connected to two seed boxes respectively on the left and right sides of the first furrowing plow 102 and the second furrowing plow 101. Several wide-width seeders 200 are mounted on the side. A wide-width input shaft 600 is connected to the front end of a wide-width transmission box 400. A wide-width output shaft 4000, which is connected to the wide-width input shaft 6000, is connected to one end of the wide-width transmission box 400 in the left-right direction. A first wide-width rotary tillage shaft 3000 is rotatably connected to the lower part of the wide-width furrowing rotary tillage seeder frame 800. Several first wide-width rotary tillage blades 1000 are arranged on the first wide-width rotary tillage shaft 3000. A gearbox 5000 is fixedly connected to the side end of the wide-width furrowing seeder frame. The wide-width output shaft 4000 provides input power to the gearbox 5000. The power output end of the gearbox 5000 is connected to the first wide-width rotary tillage shaft 3000. The wide-width rotary tiller frame 800 behind the rotary tiller shaft is rotatably connected to a second wide-width rotary tiller shaft 900. The gearbox 5000 is also connected to the second wide-width rotary tiller shaft 900 for transmission (the gearbox 5000 that provides power to the first wide-width rotary tiller shaft 3000 and the second wide-width rotary tiller shaft 900 is prior art and its internal structure does not need to be disclosed, so it is not shown in this application). Several second wide-width rotary tiller blades 2000 are arranged on the second wide-width rotary tiller shafts 900 on the left and right sides of the first furrowing plow 102 and the second furrowing plow 101, respectively. A wide-width seed metering device 200 is connected to a wide-width seed metering tube, and the seed metering port of the wide-width seed metering tube is behind the second wide-width rotary tiller blades 2000.The first wide rotary tillage shaft 3000 is connected to a soil-dividing roller 600 spaced apart in the left-right direction. The distance between the two soil-dividing rollers 600 is not greater than the minimum furrow width. The soil-dividing roller 600 is provided with spirally arranged spiral blades 700. The spiral directions of the spiral blades 700 on the two soil-dividing rollers 600 are opposite. They are used to transport the soil on both sides of the furrow away from the furrow, avoid soil accumulation on both sides of the furrow, and improve the uniformity of the soil. The narrow rotary tillage seeder 7000 does not have the furrowing component 100 in the wide furrow rotary tillage seeder, and the seed metering device on the narrow rotary tillage seeder 7000 does not need to avoid the furrowing position. Several rotary tillage blades are arranged on the two rotary tillage shafts respectively. There is no soil-dividing roller 600 structure. The rest of the structure is similar to the wide furrow rotary tillage seeder. Its specific structure is not shown in this application. It includes the following steps.

[0044] Prepare the narrow-width rotary tiller 7000 and the wide-width furrowing rotary tiller with separate narrow-width and wide-width walking devices for suspension connection;

[0045] The narrow-width rotary tiller 7000 is lowered to the set height, the narrow-width travel device moves forward, the narrow-width travel device provides power to the wide-width transmission box 400, and the narrow-width travel device navigates according to the set first working path. The working area of ​​each row of the narrow-width rotary tiller 7000 is A.

[0046] Adjust the furrowing component 100 of the wide-width furrowing rotary tillage seeder according to the actual furrowing width requirements. If the initial furrowing width is the same as the required furrowing width, there is no need to adjust the furrowing width; otherwise, move the first furrowing plow 102 and the second furrowing plow 101 simultaneously. When the distance between the first furrowing plow 102 and the second furrowing plow 101 reaches the required distance, the first furrowing plow 102 and the second furrowing plow 101 stop moving, thereby adjusting the furrowing width.

[0047] The wide-width ditching rotary tiller is lowered to a set height. The wide-width traveling device travels between two adjacent working areas A at the head. The wide-width traveling device travels along the set second working path, driving the wide-width ditching rotary tiller to perform navigation operations. The first ditching plow 102 and the second ditching plow 101 open furrows. The first wide-width rotary tiller blades 1000 and the second wide-width rotary tiller blades 2000 on both sides of the first ditching plow 102 and the second ditching plow 101 rotate twice to loosen the soil. At the same time, the soil separating roller 600 rotates, and the spiral blades 700 transport the soil on both sides of the furrow away from the furrow. The wide-width seed metering device 200 is activated, and the discharged seeds fall into the soil.

[0048] This method is suitable for planting different crops at intervals in large areas of farmland, with varying degrees of spacing, and where one of the crops requires ditching.

[0049] Example 2

[0050] Reference Figures 3 to 12 This is the second embodiment of the present invention. This embodiment provides an operation method for rotary tillage and sowing with a combination of wide and narrow widths, which can further realize the adjustment of furrow width and avoid missing furrows after the furrow width is adjusted, thereby improving the flatness of the furrow.

[0051] Specifically, a rotatable vertical shaft 124 is connected to the wide-width ditching rotary tillage seeder frame 800 behind the ditching component 100. A rotating disk 121 is fixed to the lower end of the vertical shaft 124. Several ditching blades 122 are arranged on the lower side of the rotating disk 121. The lower side of the ditching blades 122 is horizontally set. The several ditching blades 122 are attached to one end towards the center of the rotating disk 121 to further avoid missing ditching and improve the ditching effect. The bottom of the ditching blades 122 is flush with the bottom of the first ditching plow 102. The top of the ditching blades 122 is higher than the lower side of the ditching width adjustment part 101d. The rotating area of ​​the several ditching blades 122 covers the missing ditching area formed between the lower side of the ditching width adjustment part 101d and the first ditching plow 102 and the second ditching plow 101.

[0052] When the first ditching plow 102 and the second ditching plow 101 are ditching, the vertical shaft 124 rotates. The vertical shaft 124 drives the ditching blade 122 to rotate via the rotating disk 121. The ditching blade 122 mills the un-ditched area, making the un-ditched area smoother and improving the overall smoothness of the ditch.

[0053] Specifically, a connecting bracket 500 is fixed to the front of the wide-width furrowing rotary tiller frame 800. A first connecting part 102b and a second connecting part 101b are respectively fixed to the upper sides of the first furrowing plow 102 and the second furrowing plow 101, which are slidably connected to the connecting bracket 500. A width adjusting screw 123 is rotatably connected to the lower part of the connecting bracket 500. The first connecting part 102b and the second connecting part 101b are respectively threaded onto the width adjusting screw 123. b can move towards or away from each other. A guide rail 801 is fixedly connected to the frame of the wide-width furrowing seeder. A first movable part 102c and a second movable part 101a are respectively fixed to the rearwardly extended ends of the first connecting part 102b and the second connecting part 101b. Sliding grooves are respectively opened on the first movable part 102c and the second movable part 101a. The first movable part 102c and the second movable part 101a are slidably connected to the guide rail 801 through the corresponding sliding grooves. The lower sides of the first movable part 102c and the second movable part 101a are fixed. The system has a first support part and a second support part 101c. A first wide rotary tillage shaft 3000 between the two soil-dividing rollers 600 is circular. The first and second support parts 101c slide along the axial direction of the first wide rotary tillage shaft 3000. A first connecting shaft 120 is rotatably connected to the upper part of a connecting bracket 500 connecting the first and second support parts 101c. A trenching width adjusting motor 103, connected to the first connecting shaft 120, is fixedly connected to the outside of the connecting bracket 500. The first connecting shaft 120 can connect with a width adjusting screw 12. 3. Transmission connection; The upper part of the connecting bracket 500 is also rotatably connected to a second connecting shaft 119. A drive gear 110 is connected to the first connecting shaft 120. A drive wheel 109 is connected to the second connecting shaft 119 and a first transmission gear 108 is slidably connected to it. A first driven wheel is fixedly connected to the width adjusting screw 123. The drive wheel 109 is connected to the first driven wheel via a transmission belt 107. The first transmission gear 108 can cooperate with the drive gear 110. The second connecting shaft 119 and the width adjusting screw 123 are connected in a transmission connection.

[0054] Before working on work area B, when adjusting the trench width, the first transmission gear 108 moves towards the direction of the driving gear 110. When the first transmission gear 108 and the driving gear 110 mesh, the first transmission gear 108 stops moving, the trench width adjusting motor 103 activates, the first connecting shaft 120 rotates, the first connecting shaft 120 drives the first transmission gear 108 to rotate via the driving gear 110, the first transmission gear 108 drives the second connecting shaft 119 to rotate, the second connecting shaft 119 drives the driving wheel 109 to rotate, the driving wheel 109 drives the first driven wheel to rotate via the transmission belt 107, the first driven wheel drives the width adjusting screw 123 to rotate, and the width adjusting screw... Rod 123 drives the first ditching plow 102 and the second ditching plow 101 to move via the first connecting part 102b and the second connecting part 101b respectively, controlling the direction of movement of the ditching width adjusting motor 103, so that the first ditching plow 102 and the second ditching plow 101 move in the required direction. When the distance between the first ditching plow 102 and the second ditching plow 101 reaches the required distance, that is, when the ditch width formed between the first ditching plow 102 and the second ditching plow 101 reaches the required ditch width, the first transmission gear 108 moves away from the location of the driving gear 110. When the first transmission gear 108 returns to its original position, the first transmission gear 108 remains stationary. In actual implementation, such as... Figure 11 and Figure 12 As shown, a limiting plate 123a is fixed on the width adjusting screw 123 extending from the side of the connecting bracket 500 and is attached to the left side of the connecting bracket. A limiting screw hole 123a-1 is opened on the limiting plate 123a outside the width adjusting screw 123. The limiting screw is screwed into the limiting screw hole 123a-1 and the connecting bracket 500 to prevent the width adjusting screw 123 from rotating actively. When the trench width needs to be adjusted next time, the limiting screw is first loosened so that it is removed from the connecting bracket 500. Then the action of the trench width adjusting motor 103 and the linear driver 104 is controlled to adjust the trench width. The adjustment process will not be described in detail.

[0055] Specifically, a linear driver 104 is fixedly connected to the connecting bracket 500. A telescopic rod 105 capable of reciprocating linear motion in the left and right directions is connected to the linear driver 104. A transmission part 108a is fixedly connected to the first transmission gear 108. An annular connecting groove 108a-1 is opened on the transmission part 108a. A movable plate 106 is fixedly connected to the outward-extending end of the telescopic rod 105. A semi-circular groove is opened on the upward-facing end of the movable plate 106. The telescopic rod 105 passes through the groove and the connecting groove 108a-1 and is inserted into the outer edge of the first transmission gear 108. The first transmission gear 108 always rotates within the groove of the telescopic rod 105.

[0056] In this application, the linear driver 104 is preferably a linear motor. When it is necessary to adjust the position of the first transmission gear 108, the linear driver 104 is activated, the telescopic rod 105 moves, and the telescopic rod 105 drives the first transmission gear 108 to slide along the second connecting shaft 119. When the first transmission gear 108 slides to the set position, the linear driver 104 stops, realizing the engagement and disengagement of the second connecting shaft 119 and the first connecting shaft 120.

[0057] Specifically, the first connecting shaft 120 can also be connected to the vertical shaft 124 via a transmission connection. The specific structure is as follows: a transmission shaft 113 is rotatably connected to the connecting bracket 500 below the first connecting shaft 120. A driven gear 112 and a driven bevel gear 114 are connected to the transmission shaft 113. A second transmission gear 111 is also connected to the first connecting shaft 120. The second transmission gear 111 and the driven gear 112 cooperate. A second driven wheel 117 is connected to one end of the vertical shaft 124 that extends upward beyond the wide-width furrowing rotary tillage seeder frame 800. A vertically arranged rotating shaft 118 is also rotatably connected to the wide-width furrowing rotary tillage seeder frame 800. A transmission bevel gear 115 that cooperates with the transmission wheel and the driven bevel gear 114 is connected to the rotating shaft 118. The transmission wheel is connected to the second driven wheel 117 via a transmission belt 116. The connecting bracket 500 has sliding openings 501 that allow the front and rear ends of the transmission belt 116 to pass through.

[0058] After the trench width adjustment is completed, the trench width adjustment motor 103 continues to operate.
