The present invention can complete the following operations in a single operation: rotary tillage, ridging and furrowing, fertilization, sowing, covering, soil suppression, and pesticide spraying. This single field operation achieves multiple functions with high efficiency. The furrowing depth of the disc seed drill in this patented technology fluctuates with the depth of the furrow, and the first contouring mechanism has limited up-and-down adjustment capabilities, resulting in inconsistent sowing depth and insufficient furrowing and contouring capabilities. This patented technology uses a soil suppression and covering device at the rear to drive the sowing process, resulting in a longer overall structure. Furthermore, when the soil is highly viscous, the cage-type soil suppression wheel at the rear can become stuck to the soil, and in severe cases, the soil can become inert. Summary of the Invention

[0005] In order to adjust the height of the main frame of the sowing furrow, in a further technical solution, a plurality of pin holes of different heights are opened on the lifting rod, and pins are inserted into the pin holes. The pins pass through the sleeves and are inserted into the pin holes to fix the lifting rod.

[0006] In order to achieve uniform soil covering and ensure consistent soil covering thickness, in a further technical solution, a covering plate arranged in an "eight" shape is installed at the bottom of the supporting and suppressing slide plate. The covering plate is used to gather the soil to the middle, and the installation height of the covering plate is higher than the installation height of the seed furrow cutter head.

[0007] In order to complete the seeding furrow opening, sowing and covering with soil in one go and improve the working efficiency, in a further technical solution, a seeder is installed on the frame, and the end of the seeding tube of the seeder is connected to the main frame of the seeding furrow opening. The end of the seeding tube of the seeder is located behind the seeding furrow opening cutter head and in front of the covering plate arranged in an "eight" shape.

[0008] In order to use the driving wheels to compact and level the furrows, ensure the smooth movement of the entire machine, reduce the floating of the entire machine and the uneven ground, and provide stable and reliable power to the fertilizer discharge device and the seeder, in a further technical solution, ditch cleaning devices for cleaning the furrows are installed on the left and right sides of the frame, respectively. The ditch cleaning devices are installed with driving wheels, and a rear coulter is installed at the front end of the ditch cleaning devices.

DETAILED DESCRIPTION

[0014] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0015] like Figures 1 to 6As shown, the first embodiment of the present invention preferably adopts a multifunctional seed drill, on which a rotary tillage device 2 for rotary tilling the soil, a ridging and furrowing device 3 for opening ridges and furrows, a ditch clearing device 9 for cleaning ridges and furrows, a sowing furrow opening device 8 for opening sowing furrows, a seeder 10 for sowing, and a fertilizer discharge device 5 for fertilizing are installed. The ridging and furrowing devices 3 are installed on the left and right sides of the rotary tillage device 2, the ridging and furrowing devices 3 are located in front of the rotary tillage device 2, the ditch clearing device 9 is installed behind the rotary tillage device 2, the fertilizer discharge device 5 is installed behind the rotary tillage device 2, and the sowing furrow opening device 8 is installed behind the fertilizer discharge device 5. The present invention can complete the operation links of rotary tillage, ridging and furrowing, cleaning ridges and furrows, fertilizing, opening sowing furrows, sowing, covering soil, and pressing in one operation, completing multiple functions in one field operation with high efficiency.

[0016] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the sowing furrow device 8 includes a sleeve 80 installed on the frame 1, a lifting rod 81 installed in the sleeve 80, a parallelogram linkage 82 installed on the lifting rod 81, a sowing furrow main frame 83 installed on the parallelogram linkage 82, and a sowing furrow cutter head 84 and a supporting and suppressing slide 85 installed at the bottom of the sowing furrow main frame 83; the height difference H1 between the supporting and suppressing slide 85 and the sowing furrow cutter head 84 is the sowing furrow depth, the front and rear ends of the supporting and suppressing slide 85 are tilted upward, and the supporting and suppressing slide 85 is close to the ground to ensure that the sowing furrow depth is consistent; a connecting rod seat 86 is installed on the connecting rod seat 86, a hinge head 87 is installed on the hinge head 87, and a swing link 89 is installed on the hinge head 87. The swing link 89 is connected to the sowing furrow main frame 83, and a spring 88 is sleeved on the swing link 89, and the two ends of the spring 88 rest on the hinge head 87 and the swing link 89.

[0017] A plurality of latch holes 810 of different heights are provided on the lifting rod 81. The latch 800 passes through the sleeve 80 and is inserted into the latch hole 810 to fix the lifting rod 81. The latch 800 is inserted into the latch holes 810 of different heights to adjust the height of the lifting rod 81. Under the action of the parallelogram linkage mechanism 82 and the spring 88, the supporting and suppressing slide plate 85 is close to the ground to ensure that the depth of the sowing furrow is consistent. The parallelogram linkage mechanism 82 ensures that the main frame 83 of the sowing furrow is lifted and lowered vertically, and the action force of the spring 88 acts vertically on the ground. When the whole machine floats and the ground is uneven, under the joint action of the parallelogram linkage 82, spring 88, swing link 89 and its own weight, the support and suppression slide plate 85 is always pressed close to the ground, ensuring that the support and suppression slide plate always slides close to the ground, and the support and suppression slide plate rises and falls vertically, always ensuring that the depth of the sowing furrow remains unchanged, that is, the height difference H1 between the support and suppression slide plate 85 and the sowing furrow cutter head 84 remains unchanged. The sowing depth is closely related to the germination rate of the seeds. The present invention ensures the constancy of the sowing depth and has high structural stability and reliability.

[0018] like Figure 5 As shown, a covering plate 850 arranged in an "eight" shape is installed at the bottom of the supporting and suppressing slide plate 85. The covering plate 850 is used to gather the soil to the middle. The installation height of the covering plate 850 is higher than the installation height of the seed furrow cutting head 84.

[0019] like Figure 3 As shown, a seeder 10 is installed on the frame 1, and the end of the sowing tube 100 of the seeder 10 is connected to the main frame 83 for opening sowing furrows. The end of the sowing tube 100 of the seeder 10 is located behind the sowing furrow cutter head 84 and in front of the covering plate 850 arranged in an "eight" shape.

[0020] When the sowing furrow device 8 moves forward, the sowing furrow cutter head 84 first opens the sowing furrow, and then the seeder 10 sows in the sowing furrow. Finally, the covering plate 850 arranged in an "eight" shape gathers the soil to the middle to achieve soil covering, and then the end of the supporting and suppressing slide plate 85 will smooth and suppress the soil.

[0021] like Figure 2 and Figure 6 As shown, ditch cleaning devices 9 for cleaning the ditch are respectively installed on the left and right sides of the frame 1, a driving wheel 91 is installed in the ditch cleaning device 9, a rear plow 92 is installed at the front end of the ditch cleaning device 9, and the driving wheel 91 is located behind the rear plow 92. The driving wheel 91 moves in the cleaned ditch; A first transmission shaft 12, a first chain transmission mechanism 11, and a second chain transmission mechanism 13 are installed on the frame 1. The first chain transmission mechanism 11 is connected to the first transmission shaft 12 and the driving wheel 91, and the second chain transmission mechanism 13 is connected to the first transmission shaft 12 and the seeder 10. The driving wheel 91 moves to drive the first chain transmission mechanism 11, the first transmission shaft 12, the second chain transmission mechanism 13, and the seeder 10 to rotate for sowing operations.

[0022] like Figure 1 As shown, the second transmission shaft 4, the third chain transmission mechanism 6, and the fertilizer discharge device 5 are installed on the frame 1. The third chain transmission mechanism 4 is connected to the first transmission shaft 12 and the second transmission shaft 4. The second transmission shaft 4 drives the fertilizer discharge device 5 to rotate and discharge fertilizer; the driving wheel 91 moves and drives the first chain transmission mechanism 11, the first transmission shaft 12, the third chain transmission mechanism 6, the second transmission shaft 4, and the fertilizer discharge device 5 to rotate and discharge fertilizer in turn.

[0023] The multifunctional seed drill of the present invention is pulled forward by a tractor, and the rotary tillage device 2 is directly connected to the tractor drive shaft to provide rotary tillage power. When moving forward, the driving wheel 91 generates rolling friction with the ground of the ridge, and the driving wheel 91 rotates. The driving wheel 91 moves to drive the seed drill 10 to rotate for sowing and the fertilizer discharge device 5 to rotate for fertilizer discharge. Since the ditch cleaning device 9 cleans up the bulk mud in the ridge and flattens it, the probability of sticking mud is reduced when the driving wheel 91 rolls inside. The present invention utilizes the driving wheel 91 to move and compact and flatten the ridge, ensuring that the whole machine moves smoothly, reducing the floating of the whole machine and the uneven ground, further ensuring that the depth of the sowing ditch remains unchanged, the structural stability and reliability are high, and stable and reliable power can be provided to the fertilizer discharge device 5 and the seed drill 10.
