[0001] The invention belongs to the technical field of seed drills, and in particular relates to a rice dry seeding machine based on GPS satellite speed control. Background Art

[0002] The rice dry seeding machine is an agricultural mechanical equipment used to sow rice seeds in dryland environments. It can accurately sow rice seeds in the soil according to a certain row spacing, plant spacing and sowing depth, changing the traditional rice planting mode of raising seedlings and transplanting in paddy fields, and enabling rice to be directly sown and grown in dryland conditions.

[0003] The current dry rice seeder generally uses a ground wheel drive to discharge materials (rice seeds and fertilizers) during use. However, when the dry rice seeder moves to the position to be cultivated, it needs to move a certain distance before the rice seeds and fertilizers in the dry rice seeder can fall into the soil, so that there may be a situation where no seeds are sown at the head of the field.

[0004] In addition, when the dry rice seeding machine is in use, if the uncultivated space on one side of the field is narrow, the wider dry rice seeding machine may cause part of the material to fall repeatedly to the cultivated position, causing the field to be cultivated repeatedly;

[0034] The present invention will be further described below in conjunction with the embodiments.

[0035] The following examples are used to illustrate the present invention, but they cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0036] Embodiment 1:

[0037] See also Figure 1-8 The present invention provides a rice dry seeding machine based on GPS satellite speed control, comprising a support assembly 1, a feeding assembly 2, a furrowing assembly 3, a seedling belt assembly 5, a soil covering assembly 6 and a GPS satellite controller 8, wherein the support assembly 1 comprises a support frame 11, a connecting member 12 and a first fixing frame 13;

[0038] The feeding assembly 2 includes a base fertilizer chamber 21, a bacterial fertilizer chamber 22, a rice seed chamber 23, a plurality of feeding rollers 24, a plurality of connecting sleeves 25 and a plurality of first connecting rods 26. A plurality of feeding tubes 27 are connected to the bottom of the rice seed chamber 23. The plurality of feeding rollers 24 are rotatably connected in the feeding tubes 27. The plurality of feeding rollers 24 are connected to the connecting sleeves 25. The feeding rollers 24 on both sides are rotatably connected in the support frame 11. The ends of the feeding rollers 24 on both sides that are far away from each other are connected to the motor 28. The two motors 28 are respectively connected to the two sides of the support frame 11. The two ends of the plurality of first connecting rods 26 are plugged into the connecting sleeves 25. The plurality of feeding rollers 24 are rotatably connected to the bottom of the rice seed chamber 23.

[0039] The seedling belt assembly 5 includes a rotating rod 51, which is rotatably connected to the support frame 11. A plurality of belt pressing teeth 52 are connected to the outside of the rotating rod 51. The middle part of the rotating rod 51 is connected to a driving member 53, and the driving member 53 is connected to the support frame 11. By setting the driving member 53, the driving member 53 can be composed of a fixed box, a worm, a worm wheel and a driving motor. The worm wheel is clamped on the outside of the rotating rod 51, the worm is meshed with the worm wheel, and the driving motor is connected to the worm. The rotating rod 51 is rotatably connected in the fixed phase, and the working driving motor can transmit power to the middle part of the rotating rod 51 through the worm and the worm wheel, and then the rotating rod 51 can rotate;

[0040] One side of the support frame 11 is connected to the GPS satellite controller 8, and the signal output end of the GPS satellite controller 8 is connected to the signal input ends of the two motors 28 through a cable. By setting the GPS satellite controller 8, the GPS satellite controller 8 is composed of a GPS receiving module, a control module, a motor control module, and a signal interface. The signal interface can be connected to the signal input end of the motor 28 through a cable.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the support frame 11 is connected to the connecting member 12 , and the support frame 11 is connected to the first fixing frame 13 .

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, the furrowing assembly 3 includes a second fixing frame 31 and a plurality of furrow openers 32 . The second fixing frame 31 is connected to the support frame 11 , and the plurality of furrow openers 32 are connected to the second fixing frame 31 .

[0043] like Figure 5 As shown, the soil covering assembly 6 includes a soil covering device 61 , and the soil covering device 61 is rotatably connected in the support frame 11 .

[0044] like Figure 5 As shown, the bacterial fertilizer chamber 22 is arranged between the base fertilizer chamber 21 and the rice seed chamber 23 , and the first fixing frame 13 is close to the rice seed chamber 23 .

[0045] Embodiment 2:

[0046] Based on the first embodiment, the second embodiment is proposed: it also includes a soil pressing assembly 7, which includes a pressing roller 71, both ends of which are connected to two shaft sleeves 72 respectively through a plurality of bolts 75, a connecting groove 73 is provided in the pressing roller 71, and second connecting rods 74 are slidably connected in the two shaft sleeves 72, and the two second connecting rods 74 are connected to the support frame 11 through bolts 75. By setting the bolts 75, the bolts 75 can connect the second connecting rods 74 and the support frame 11 together;

[0047] Two positioning plates 76 are connected inside the support frame 11 , and both positioning plates 76 are sleeved outside the second connecting rod 74 . By setting the positioning plates 76 , the positioning plates 76 on both sides can limit the moving pressure roller 71 , so that the pressure roller 71 rotates between the two positioning plates 76 .

[0048] Because the two ends of the pressure roller 71 are movably connected to the two second connecting rods 74 through the shaft sleeves 72, and because the pressure roller 71 is long, when the pressure roller 71 moves during use, the moving pressure roller 71 can move along its axial direction inside the shaft sleeve 72, so that the impact force generated by the moving pressure roller 71 is not easy to cause damage to the shaft sleeve 72. When the shaft sleeve 72 is damaged, it is only necessary to unscrew a plurality of bolts 75 from the pressure roller 71, and then pull the second connecting rod 74 out of the shaft sleeve 72 for disassembly, which is convenient to operate. Through this special connection structure, the pressure roller 71 can maintain the damaged soil compacting component 7 without using professional tools, which is convenient to operate, making the seeder not easy to be repaired. The damaged soil pressing assembly 7 takes a long time and thus affects the farming season, solving the problem that "the pressing roller in the dry rice seeding machine is installed through the bearing, and the connection between the two ends of the pressing roller and the bearing is an interference fit connection. When the pressing roller is rotating, because the length of the pressing roller is about 3 meters, the longer pressing roller will move during the rotation, so that the impact force generated during the movement of the pressing roller will impact the bearing, making the bearing easy to be damaged, and when the bearing is damaged, professional staff are required to use special tools to remove the pressing roller from the bearing. The damaged pressing roller is inconvenient to repair and the repair time is too long. The dry rice seeding machine may affect the normal farming season due to the long repair time."

[0049] like Figure 6 , Figure 7 and Figure 8 As shown, the sleeve 72 is composed of an outer ring, a roller, an inner ring and a retaining frame. The outer ring in the sleeve 72 is connected to the pressure roller 71 through a plurality of bolts 75. The inner wall of the connecting sleeve 25 and the inner ring is provided with a circular hexagonal groove, and the shape of the connecting groove 73 is set to be a circular hexagonal groove.

[0050] like Figure 6 , Figure 7 and Figure 8 As shown, the first connecting rod 26 and the second connecting rod 74 are both configured as circular hexagonal shafts.

[0051] Embodiment three:

[0052] Based on the first embodiment, the third embodiment is proposed, which further includes a soil leveling assembly 4 . The soil leveling assembly 4 includes a spiral conveying rod 41 . The spiral conveying rod 41 is rotatably connected in the support frame 11 .

[0053] like Figure 4 and Figure 5As shown, the furrow opener 32, the spiral conveying rod 41, the belt pressing teeth 52, the soil covering device 61 and the pressing roller 71 are sequentially distributed from front to back.

[0054] During actual use of the seeder, the soil leveling component and the soil covering component can be reduced according to actual conditions.

[0055] The working principle and use process of the present invention are as follows: when the seeder needs to be used, it is connected to the tractor through the connecting piece 12, and the motor 28 can be connected to the fertilizer rollers in the base fertilizer chamber 21 and the bacterial fertilizer chamber 22 through an external transmission component (not shown). The operator stands on the first fixed frame 13, and then pours the base fertilizer and bacterial fertilizer into the base fertilizer chamber 21 and the bacterial fertilizer chamber 22 respectively, and then pours the rice seeds into the rice seed chamber 23. Because the feeding component 2 is set as a stepped structure, that is, the feeding port of the base fertilizer chamber 21 protrudes above the bacterial fertilizer chamber 22 and the rice seed chamber 23, the operator only needs to stand on the first fixed frame 13 to conveniently pour the base fertilizer, bacterial fertilizer and rice seeds into the base fertilizer chamber 21, the bacterial fertilizer chamber 22 and the rice seed chamber 23;

[0056] When the planter moves to a suitable position, the two motors 28 are controlled to work, and the working motors 28 drive the feed rollers 24 on both sides to rotate. The two rotating feed rollers 24 drive the remaining feed rollers 24 to rotate through the first connecting rods 26. The rotating feed rollers 24 can transport the rice seeds in the rice seed cavity 23 downward and discharge them through the bottom of the feed pipe 27.

[0057] When the planter is moving, the GPS satellite controller 8 controls the rotation speed of the two motors 28 according to the speed of the planter. When the planter is moving fast, the rotation speed of the two motors 28 is accelerated, and when the planter is moving slowly, the rotation speed of the two motors 28 is slowed down, so that the rotating discharge roller 24 can evenly push the rice seeds out from the bottom of the discharge pipe 27;

[0058] The working principle of the GPS satellite controller 8 controlling the rotation speed of the two motors 28 is as follows: the GPS receiving module in the GPS satellite controller 8 receives the signals containing the satellite position, time and other information continuously sent by the GPS satellite to the ground, the GPS receiving module captures and receives these signals, and solves its own position, speed and other information therefrom, and then transmits the data to the control module in the GPS satellite controller 8, the speed information solved by the control module is transmitted to the motor control module (such as industrial control computer, PLC, motor driver, etc.) in the GPS satellite controller 8 responsible for controlling the motor 28 through a data transmission line (such as a serial port, USB port, CAN bus, etc.), after the motor control module in the GPS satellite controller 8 receives the GPS speed data, it processes it according to a preset control algorithm (if the target speed is set, the control algorithm will calculate the difference between the current speed and the target speed, and a common control algorithm is a PID control algorithm, which calculates the control amount according to the speed difference, the integral of the difference and the differential of the difference) to achieve precise regulation of the rotation speed of the motor 28;

[0059] A control quantity calculated according to a control algorithm of a motor control module;

[0060] The motor control module generates corresponding motor 28 control instructions, which may be signals that change the motor 28 input voltage, current, frequency, etc., depending on the type of motor 28 and the speed control method used;

[0061] If the motor 28 is set as an AC motor 28, the command generated by the motor control module will change the power frequency output by the inverter, thereby changing the speed of the motor 28; when the GPS speed data shows that the movement speed is lower than the target speed, the control unit will increase the output frequency of the inverter to increase the speed of the motor 28; otherwise, the frequency will be reduced to reduce the speed of the motor 28.

[0062] If the motor 28 is configured as a DC motor 28, the speed can be adjusted by changing the armature voltage or the field current of the motor 28;

[0063] The motor control module outputs a corresponding voltage or current regulation signal according to the speed information and the control algorithm to control the speed of the motor 28, for example, by using PWM (pulse width modulation) technology to change the duty cycle of the armature voltage of the motor 28, thereby achieving the regulation of the speed of the motor 28;

[0064] When the planter is in motion, a plurality of furrow openers 32 open furrows on the ground. Since the furrow openers 32 are configured as a single furrow opener disc device, they are less likely to get soil stuck than double furrow openers, and maintenance is simpler and more convenient.

[0065] Then the rotating screw conveyor rod 41 can integrate and level the land after the deep trenching, so as to facilitate the next process;

[0066] Because the belt pressing teeth 52 are composed of two 3.5 cm wide and 4 cm deep furrow pressing rotating discs, and a serrated isolation disc with a diameter about 5 cm larger than the furrow pressing disc is provided in the middle, the isolation disc in the belt pressing teeth 52 divides the seedling belt into two left and right strips, thereby avoiding the phenomenon of rice seeds gathering when sowing in a single seedling belt. Moreover, the rotation of the serrated isolation disc can break up the hard soil blocks and residual stalks on the soil, thereby ensuring that the soil under the rice seeds in the seedling belt is loose, which is conducive to the growth of the rice seed root system. Moreover, the rotating driving member 53 is set in the middle, and the power is applied by the middle driving member 53, which solves the problem that the middle up and down vibration is easily generated due to the excessive length of the transmission shaft, affecting the depth of the seedling belt, and at the same time makes the power output more reliable.

[0067] Then, the rotating soil cover 61 with a blade can produce soft soil to quickly cover the seeds; then the rotating pressure roller 71 compacts the soft soil produced by the front soil cover 61 to facilitate retaining moisture in the soil and improving the seed germination rate.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
