[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0012] The specific implementation mode of the utility model is that the drawings do not limit the utility model to the specific embodiments disclosed and described herein, and the drawings are not necessarily drawn to scale, but emphasize the principle of the preferred embodiment that can be clearly explained. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. A new double-row adjustable independent contouring ditching monomer includes a monomer frame 1, a floating traction rod 2, an adjustment screw rod 3, a right ditching disc support arm 4, a left ditching disc support arm 5, a left contouring wheel support arm 6, a right contouring wheel support wall 7. A right contouring wheel 8, Left profiling wheel 9, left ditching disc 10, right ditching disc 11, swing shaft 12, swing shaft screw mounting plate 13, fixing screw 14, left adjusting screw 15, right adjusting screw 16, right stopper 17, left stopper 18, limiting stopper 19, left transmission shaft 20, swing shaft screw 21, left seed meter 22, left ditching disc support arm shaft 23, left profiling wheel support arm shaft 24, right ditching disc support arm shaft 25, right profiling wheel support arm shaft 26, intermediate shaft 27, sprocket 28, adjustment plate 29, scale line 30, right seed meter 31, connecting pin 32, right transmission shaft 33, mounting seat 34, adjusting washer 35, right external thread screw tube 36, left external thread screw tube 37, swing shaft mounting lug 38. A floating traction rod 2 for traction is installed at the front end of the single frame 1, and a rotatable intermediate shaft 27 is installed on the upper part of the single frame. A sprocket 28 is installed on the intermediate shaft. The sprocket 28 is used to receive power from a gearbox (not shown) and transmit the power to the intermediate shaft 27. The intermediate shaft 27 then evenly transmits the power to the left transmission shaft 20 and the right transmission shaft 33. The left transmission shaft 20 then transmits the power to the left seeding device 22, and the right transmission shaft 33 then transmits the power to the right seeding device 31. The two transmission shafts use the same transmission ratio to make the angular frequency of the seeding discs of the two seeding devices consistent during operation and the rotation speed consistent;

[0013] When initially installed, the left seeding device 22 is positioned relative to the right seeding device 31 so that the seeding discs (finger clamps) of the two seeding devices have the same initial angle in space, that is, the seeding time of the two seeding devices is consistent (seeding at the same time), forming a double row of crooked seedlings. The so-called crooked seedlings refer to the direction in which the seeds advance along the row. The seeds of the left and right rows appear alternately in the left and right rows according to the plant spacing. The two seeding devices are configured with a front-to-back offset configuration. During operation, the front-to-back distance is selected to be equal to the plant spacing (taking corn as an example, but not limited to this, for illustration only). Since there is a mechanical hinge between the left seeding device 22 and the adjustment plate, the adjustment plate can drive the left seeding device 22 to move forward and backward relative to the single frame 1. Adjustment engraved lines 30 are engraved on the limit stop bar 19 and the adjustment plate 29, with 0.5 cm spacing. One of the long lines is the reference line. Its position is centered and is also the middle value of the commonly used plant spacing, and is also the actual front-to-back distance between the left (rear) and right (front) seeding devices (for example, 20 cm, but this is just an example and not limited to this). Other plant spacings are obtained by moving the adjustment plate forward and backward;

[0014] like Figure 4The small circle represents seeds and the four squares represent seed-dispensers. For plants with large plant spacing, such as corn, the distance between the front and rear seed-dispensers should be equal to the plant spacing. You can also try sowing for a while, dig up the soil and make careful adjustments based on the actual situation. The ideal shape is an isosceles triangle formed by adjacent seeds; the rear seeding device position of seeds with small plant spacing is at an odd multiple of the plant spacing, and a trial sowing can be carried out for a period of time, and the soil can be carefully adjusted to achieve an ideal isosceles triangle; seeds with small plant spacing can be trial sown for a period of time, and the adjustment plate can be moved forward or backward according to the specific situation to obtain the best pattern (triangular seedlings). Adjustment instructions: First, select the plant spacing according to the gearbox (not shown). Then first loosen the fixing screw 14, and adjust the distance between the two seeding devices according to the plant spacing so that it is equal to the plant spacing. After the adjustment is completed, tighten the fixing screw 14 to keep the adjustment plate 29 stationary during operation. A right ditching disc support arm shaft 25 is fixedly installed at the lower right side of the single frame 1, and a right ditching disc support arm 4 is rotatably installed on the right ditching disc support arm shaft 25. A rotatable right ditching disc 11 is installed below the rear end of the right ditching disc support arm 4. 4 is provided with a detachable right seeding device 31 above the rear end. A right stopper 17 is fixedly mounted at the front end of the right ditching disc support arm 4, and its function is to prevent the right profiling wheel 8 from falling too much. A right adjusting screw 16 is installed on the right ditching disc support arm 4, and its function is to limit the rising height of the right profiling wheel 8, that is, to limit the burying depth of the right ditching disc 11, that is, the so-called right ditching depth. A detachable right profiling wheel support arm shaft 26 is installed below the front section of the right ditching disc support arm 4, and a right profiling wheel support arm 7 is rotatably mounted on the right profiling wheel support arm shaft 26. A right external thread screw tube 36 with an external thread screw that can be rotatably mounted between the right profiling wheel support arm 7 and the right profiling wheel support arm shaft 26 is provided, and the right external thread screw tube 36 cooperates with the internal thread screw of the right profiling wheel support arm 7 to adjust the distance between the right profiling wheel 8 and the right ditching disc 11. This device has been popularized on existing no-till machines for many years. This machine is only used for the convenience of adjustment and no other purpose. If there is any infringement, other adjustment methods can be used instead, such as the adjustment washers between the left and right ditching disc arms and the single frame of this machine. Changing the number of washers or changing the position of washers can also complete the adjustment task. A rotatable right profiling wheel 8 is installed at the rear end of the right profiling wheel arm 7, and a detachable row spacing adjustment washer 35 is mounted on the right ditching disc arm shaft 25. When adjusting, the adjustment washer 35 can be moved to the right ditching disc arm The right ditching disc support arm 4 is close to the single frame, that is, the row spacing is reduced. A swing shaft mounting lug 38 is fixedly installed in the middle of the rear section of the right ditching disc support arm 4. The swing shaft mounting lug 38 has a swing shaft mounting hole. The front end of the swing shaft 12 is inserted into the swing shaft mounting hole and can rotate freely. The rear end of the swing shaft 12 is inserted into the swing shaft mounting hole of the left swing shaft mounting lug 38 and can rotate freely. The left swing shaft mounting lug 38 is fixedly installed in the middle of the rear section of the left ditching disc support arm 5.

[0015] The swing shaft 12 is movably connected to the lower end of the swing shaft screw 21 through the middle connecting pin 32. The swing shaft 12 can rotate around the connecting pin 32 during operation. The upper end of the swing shaft screw 21 is fixed to the swing shaft screw mounting plate 13 with a screw. The swing shaft screw mounting plate 13 has a rectangular screw hole for the swing shaft screw to move back and forth. The swing shaft screw mounting plate 13 is fixed to the single frame 1, so the connecting pin 32 at the center of the swing shaft 12 does not move when the swing shaft 12 is working. The two ends of the swing shaft 12 can float up and down with the swing shaft mounting lugs 38 on both sides, that is, one side of the grooved disc on both sides rises and the other side falls, thus realizing the independent profiling of the two rows. At the lower left side of the single frame 1, the adjustment plate 29 is fixed by the screw 14 It is installed in the shallow groove formed between the upper and lower limit stop bars 19. When adjusting, loosen the fixing screw 14, and the adjustment plate 29 can move forward and backward in the shallow groove. The adjustment screw 3 is movably installed between the adjustment plate 29 and the single frame 1 through two mounting seats 34. The adjustment screw is a two-way screw (left-handed at the front end and right-handed at the rear end). Rotating the adjustment screw 3 can drive the adjustment plate 29 to move forward and backward relative to the single frame 1. The left side of the adjustment plate 29 is fixedly installed with the left ditching disc support arm shaft 23. On the left ditching disc support arm shaft 23; the left ditching disc support arm 5 is rotatably installed. A swing shaft mounting lug 38 is fixedly installed in the middle of the rear section of the left ditching disc support arm 5.
