[0044] The application principle of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] Embodiment 1:

[0046] like Figure 1-Figure 11 As shown, a foldable multifunctional all-in-one grain farming machine includes a Z-shaped armrest 2 and a body frame structure.

[0047] A solar panel 1 is fixed on the Z-shaped handrail 2; the left end of the Z-shaped handrail 2 is connected to the handrail connector 5, and the Z-shaped handrail 2 and the long vertical pole 9 are both installed with a diagonal brace connecting block 3, the Z-shaped handrail 2 is connected to one end of the diagonal rod 4 through the diagonal brace connecting block 3, and the other end of the diagonal rod 4 is connected to the diagonal brace connecting block 3 on the long vertical pole 9, and the diagonal brace connecting block 3 and the diagonal rod 4 are fixed by an external hexagonal bolt 60; the Z-shaped handrail connector 5 is connected to the upper U-shaped fork 7 through a rotating shaft 6 and is fixed to the top of the long vertical pole 9 through an internal hexagonal bolt 8, and a bolt hole 44 is provided on the Z-shaped handrail;

[0048] The fuselage frame is composed of a long vertical rod 9, a vertical rod 58 and a horizontal rod 59; the top and bottom surfaces of the fuselage frame are composed of vertical rods 58 and horizontal rods 59 connected end to end by the long vertical rod 9 to form a frame; the front and rear of the fuselage frame are composed of horizontal rods 59 and long vertical rods 9 connected end to end; the left and right sides of the fuselage frame are composed of vertical rods 58 and long vertical rods 9 connected end to end. A vertical rod 58 is installed between the two horizontal rods 59 located on the top surface of the fuselage frame, and two short rods 35 are installed between the two vertical rods 58 near the left side of the fuselage frame. Two vertical rods 58 are installed between the two horizontal rods 59 located on the bottom surface of the fuselage frame. A rectangular frame structure is installed on both vertical rods 58. The rectangular frame structure is composed of two vertical rods 58 and two short rods 35 connected end to end, and is located on the bottom surface of the fuselage frame. The two rectangular frame structures are connected by short rods 35. Short rods 35 are installed on both horizontal rods 59 located on the bottom surface of the fuselage frame.

[0049] A control panel 10 is installed between the two cross bars 59 in front of the fuselage frame. By operating the control panel 10, the stepper motor 26 is driven to rotate the rotary tiller 30. As the seeder moves forward, the rotary tiller 30, the plowshare 54, the seed flow control shaft 19, the water pipe 45, and the burying head 16 are operated in sequence, so that the sowing process of grains can be completed in one step, including rotary tillage, furrowing, sowing, watering, and burying. The device has a simple structure and a high sowing efficiency, which simplifies the complex process.

[0050] A fixing seat 41 is installed on the two cross bars 59 on the top surface of the fuselage frame, a water tank rod 42 is connected to the fixing seat 41, a water tank rod 42 is connected to the water tank 40, a water injection hole 43 is provided on the top cover of the water tank 40, the diameter of the water injection hole 43 is 35 mm, a water pipe 45 is connected to the lower end of the water tank 40, the diameter of the water pipe 45 is 22 mm, a ball valve 46 is connected to the middle position of the water pipe 45, and a buried head 16 is connected to the water outlet 47 at the lower end of the water pipe 45 by bolts;

[0051] A seed box 38 is installed on the side of the vertical rod 58 in the middle of the top surface of the fuselage frame. A cover plate 37 is provided on the top of the seed box 38. A seed model 66 is embedded at the bottom of the seed box 38. Two groups of throttling blocks 61 are connected below. A square funnel 62 is connected below the throttling blocks 61. The lower part of the square funnel 62 is connected to the seed tube 52. A seed guide head 53 is installed at the end of the seed tube 52.

[0052] Support blocks 18 are fixedly mounted on the two cross bars 59 on the bottom of the fuselage frame, bearing seats 17 are mounted above the support blocks 18, seed flow control shafts 19 are connected to the bearing seats 17, and the seed flow control shafts 19 run through the two groups of throttling blocks 61. Sprockets I49 and II51 with different numbers of teeth are mounted on the seed flow control shafts 19.

[0053] The short rods 35 of the two rectangular frames on the bottom surface of the fuselage frame are both equipped with bearing seats 48, and the bearing seats 48 are equipped with transition shafts 65, and the transition shafts 65 are equipped with toothed sprockets I49 and II51 with different numbers of teeth.

[0054] A front wheel axle 55 is installed on the short rod 35 on the two cross bars 59 on the bottom surface of the fuselage frame, and a toothed sprocket I49 is installed on the front wheel axle 55.

[0055] The toothed sprocket I49 on the seed flow control shaft 19 is connected to the toothed sprocket II51 on the transition shaft 65 via a chain 50 , and the toothed sprocket II51 on the transition shaft 65 is connected to the toothed sprocket I49 on the front wheel shaft 55 via a chain 50 .

[0056] Universal wheel brackets 12 are installed at the bottom ends of the two long vertical poles 9 on the right side of the fuselage frame. Universal wheels 13 are connected to the long vertical poles 9 through universal wheel brackets 12 and are fixed by bolts. Front wheels 23 are installed at both ends of the front wheel shaft 55. Universal wheels 13 and front wheels 23 are 8-inch rubber wheels. Front wheels 23 are directional wheels that play a supporting and guiding role; universal wheels 13 have a self-locking function and play a steering and locking role. The circumference C of the front wheel is:

[0057] The rotation of the front wheel of the push device drives the front wheel shaft 55 to rotate, and the front wheel shaft 55 realizes synchronous rotation through the chain 50 and the toothed sprocket II51 at the top of the transition shaft 65, and the toothed sprocket II51 in the middle of the transition shaft 65 realizes synchronous rotation through the chain 50 and the toothed sprocket I49 on the seed flow control shaft 19. The transmission ratio can be adjusted by sliding switching between the toothed sprocket I49 and the toothed sprocket II51 on each shaft, thereby changing the nest distance to meet the needs of different seeds. According to the switching of the number of teeth between the toothed sprockets, the transmission ratio can be divided into three different gears, and then according to the circumference C of the front wheel, the nest distance under the transmission ratio of the three different gears can be obtained.

[0058] When the transmission ratio I1=(a / b)*(a / b), the nest distance is w1=I1*C;

[0059] When the transmission ratio I2=(a / b)*(a / a), the nest distance is w2=I2*C;

[0060] When the transmission ratio I3=(a / b)*(b / a), the nest distance is w3=I3*C;

[0061] Wherein a is the number of teeth of the toothed sprocket I49, and b is the number of teeth of the toothed sprocket II51.

[0062] The front wheel uses an 8-inch (diameter is about 203.2mm) rubber wheel, and its circumference C is:

[0063] C=π·D=3.14×203.2=638.048mm

[0064] If two 10-tooth sprockets II51 and three 20-tooth sprockets I49 are used (taking this as an example, the sprockets can also be replaced with other numbers of teeth), they are installed on the front wheel shaft 55 (one with 20 teeth), the transition shaft (one each with 6510 teeth and 20 teeth) and the seed flow control shaft 19 (one each with 10 teeth and 20 teeth), the two sprockets on the same shaft can be arbitrarily slipped and switched to change the transmission ratio, thereby changing the nest distance to meet the needs of different types of seeds. A foldable multifunctional grain farming machine is divided into three different gears according to the transmission ratio, and the number of teeth is switched as follows:

[0065] When the transmission ratio i1 = (10 / 20)*(10 / 20) = 1 / 4, the nest distance is about 160 mm;

[0066] When the transmission ratio i2 = (10 / 20)*(10 / 10) = 1 / 2, the nest distance is about 319 mm;

[0067] When the transmission ratio i3 = (10 / 20)*(20 / 10) = 1, the nest distance is about 638 mm;

[0068] Therefore, the sprocket with the above number of teeth can realize the cultivation of crops with 160mm, 319mm and 638mm nest spacing. If the nest spacing requirements of other crops are changed, only the corresponding number of sprocket teeth is needed.

[0069] A square connecting rod 20 is fixed to the vertical rod 58 in the middle of the bottom surface of the fuselage frame near the left side by a hexagonal bolt, and a plowshare 54 is installed at the bottom end of the square connecting rod 20.

[0070] A depth adjustment rod 36 is installed between the two short rods 35 on the top surface of the fuselage frame, and an adjustment bolt 34 is installed on the short rod 35. The depth adjustment rod 36 can move between the two short rods 35 and is locked by the adjustment bolt 34.

[0071] Two folding fixing buckles 33 are installed on the top of the two long vertical rods 9 on the left side of the fuselage frame.

[0072] A concave rotating bracket 24 is installed on the vertical rod 58 at the bottom of the left side of the fuselage frame, and the concave rotating bracket 24 is connected to the bottom plate 25 through a convex block 56. Two groups of L-shaped brackets 64 are arranged at the left end of the bottom plate 25 and are connected to the left and right triangular baffles 27. A stepper motor 26 and a battery 32 are respectively installed in the middle of the bottom plate 25. A stepper driver 63 is installed on the bottom plate 25. The rear end of the bottom plate 25 is connected to a depth adjustment rod 36; the left and right triangular baffles 27 are fixedly connected through three optical axes 31, a pulley 29 is fixed in the middle of the front optical axis 31, and the pulley 29 is connected to the output shaft of the stepper motor 26 through a belt 57. The left and right ends of the front optical axis 31 are connected to the triangular baffle 27 through bearings, and a pair of rotary tillage heads 30 are fixed in the middle in a shaft hole matching manner, and five rotary tillage blades 28 are evenly distributed on the circumference of the rotary tillage heads 30; the stepper motor 26 and the battery 32 are connected through a wire;

[0073] The control panel 10 is provided with a power on button 67 , a power off button 68 , a start button 14 , a stop button 11 and a speed control knob 15 .

[0074] The seed model library 39 is fixed to the cross bar 59 on the top surface of the fuselage frame by means of hexagon socket bolts and is located on the side of the seed box 38 .

[0075] The buried head 16 is welded into a W-shape with a 60mm wide angle iron, and the buried part opening is a W-shaped small nail rake structure, which can better prevent soil compaction and hardening compared to a flat structure. The material is the commonly used angle iron on the market, using a welding process, and an oblique groove is opened at the bottom.

[0076] The stepper motor 26 uses a 24 / 36V safety voltage and is equipped with a stepper driver 63 .

[0077] The seed flow control shaft 19 crosses the throttling block 61, and there are two sets of countersunk holes on the seed flow control shaft 19. During the rotation process, the countersunk holes first receive the seeds, then store the seeds, and then after rotating 180°, the seeds are accurately dropped into the square funnel 62 below. Finally, the square funnel 62 drops the seeds through the seed tube 52 below.

[0078] The vertical rod 9, the vertical rod 58 and the horizontal rod 59 are all 40 mm standard aluminum profiles.

[0079] The Z-shaped handrail 2, the diagonal rod 4 and the vertical rod 9 are arranged to form a triangle shape.

[0080] The two left and right triangular baffles 27 are fixed to the three optical axes 31, and the three axis holes used are distributed in an isosceles triangle.

[0081] The Z-shaped handrail can be rotated 180 degrees and folded after the hexagonal bolt 60 is removed. When in place, the bolt hole 44 coincides with the bolt hole on the fixing buckle 33, and the hexagonal bolt 60 is passed through the middle to lock it.

[0082] The mechanical movement in this design is mainly divided into five parts: rotary tillage, furrowing, sowing, watering, and covering. First, according to the diameter of the grain seeds to be sown, a suitable seed mold is selected from the seed model library 39 and installed on the seed box 38. Next, the ball valve 46 at the lower end of the water tank 40 is adjusted to control the water flow according to the seed's preference for water. Next, the start button 14 on the control panel 10 is activated, and the speed of the stepper motor 26 is adjusted through the speed adjustment button 15 to adjust the speed of the rotary tiller 30. Next, the depth adjustment rod 36 is moved to adjust the depth of rotary tillage, and finally the seeder is pushed forward to carry out the sowing operation.

[0083] Working principle: First, the rotary tillage blades 28 on the rotary tillage head 30 are used to remove weeds in the field and loosen the soil, and then the plowshare 54 is used to open the furrows and prepare for sowing. Secondly, the grain seeds enter the square funnel 62, the seed tube 52, and finally fall into the ditch through the seed guide head 53 through the throttling block 61 and the seed flow control shaft 19 below the seed box 38, so as to achieve sowing. Finally, the water in the water tank 40 passes through the water pipe 45 and the ball valve 46 in turn to achieve the irrigation process, and at the same time, the burying head 16 realizes the burying process of covering the seeds with soil, thereby completing the sowing task.

[0084] Rotary tillage process: The solar panel 1 generates electricity using light energy and stores the electricity in the battery 32. The battery 32 controls the stepper motor 26 to operate through the stepper motor driver 63, thereby driving the pulley 29 and the rotary tiller 30 to rotate. The rotary tillage depth of the rotary tiller 30 can be controlled by adjusting the angle of the depth adjustment rod 36. When the planter moves forward, the fan-shaped rotary tillage blades 28 on the rotary tiller 30 fluff up the soil, thereby completing the rotary tillage process.

[0085] Furrowing process: The fan-shaped rotary tillage blade 28 on the double rotary tiller 30 has a special function. The two blades of the rotary tillage blade 30 will intersect at a point in the front and lower part when rotating, forming an angle (usually 9°-12°). When working, the two blades will penetrate into the soil under the action of their own weight and the additional pressure of the regulator, and the two blades will roll forward, pushing the soil away and to both sides, and then the plows 54 on the left and right sides will further expand the furrows opened by the rotary tillage blade 30 to form the required furrows, ready for seed sowing.

[0086] Sowing process: The seed box is designed to be W-shaped. The seeds enter the throttling block 61 through two mold holes and then flow into the seed flow control shaft 19. The seed flow control shaft 19 rotates synchronously under the drive of the sprockets 49 and 51 and the chain 50. After the seed flow control shaft 19 rotates 180°, the stored seeds fall into the square funnel 62 and the seed tube 52 below, and finally flow out through the seed guide head 53, thereby achieving sowing. The W-shaped structure of the seed box can divide the seeds into two different flow directions, which fall into two symmetrical small grooves respectively, forming two seed rows. Therefore, this furrow opener can sow two rows of different or identical seeds at the same time. The rotary tiller 30 can not only cut the soil and cut off weeds, but also level the ground. It can also be operated when the ground conditions are poor, the surface soil is relatively wet, and there are many stubbles.

[0087] Watering process: first adjust the water pipe 45 to just aim at the ditch. After the seeds fall into the ditch, water them periodically by controlling the switch of the watering ball valve 46 mechanism to ensure that the cultivated nest part of each seed can absorb water.

[0088] Soil covering process: The burying head 16 is arranged on the fixing frame at the bottom of the water pipe 45. With the speed of the device moving, the burying head 16 can cover the soil and bury it in the same direction. The burying depth can be adjusted. The burying head is designed as an integral structure to ensure its working rigidity.

[0089] Folding process: first loosen the two hexagonal bolts 60 connecting the lower part of the Z-shaped handrail 2 and the diagonal rod 4. After removing the hexagonal bolts 60, the Z-shaped handrail 2 can be rotated 180° around the U-shaped fork 7 at the top of the long vertical rod 9.
