[0025] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1-Figure 8As shown, an electric-controlled fixed-point fertilization and dispensing device for agriculture includes a cart, and the cart is fixed with a fertilizer box 2, a battery 3 and a controller 4. A sowing mechanism is installed on the left and right parts of the cart, and the sowing mechanism includes an electric-driven telescopic mechanism and a support frame 7. The cart is installed with a support frame 7, and a plurality of guide cylinders 8 are fixed on the support frame 7 in sequence from front to back. The guide cylinders 8 on the left and right sides of the cart are inclined outward and downward, and a feed pipe 9 is fixedly connected to the upper part of the guide cylinder 8. A main ground plug 10 is axially slidably connected in each of the guide cylinders 8. The electric-driven telescopic mechanism is connected to the main ground plug 10 to control the main ground plug 10 to slide reciprocatingly along the guide cylinder 8. The bottom of the main ground plug 10 is axially slidably connected to an auxiliary ground plug 11, and the axial bottom end of the auxiliary ground plug 11 is set with a pointed tip and is axially connected to the main ground plug 10. A temporary storage groove 12 is commonly provided in the two parts, and the temporary storage groove 12 passes through the axial end of the bottom of the main ground plug 10, and radially passes through the upper part of the main ground plug 10, and the temporary storage groove 12 radially passes through the bottom of the auxiliary ground plug 11, and a plurality of downwardly inclined or vertical discharge pipes 13 are fixed at the bottom of the fertilizer box 2, and the discharge pipe 13 is connected to the feed pipe 9 through a surplus hose, and an elastic member is commonly fixed between the auxiliary ground plug 11 and the main ground plug 10, and the auxiliary ground plug 11 always has a tendency to approach the main ground plug 10 under the elastic force of the elastic member to achieve the blocking of the bottom of the temporary storage groove 12, and the upper part of the temporary storage groove 12 is still left with an opening when the auxiliary ground plug 11 and the main ground plug 10 are blocked, and the opening of the temporary storage groove 12 can correspond to and be connected with the feed pipe 9, and the battery 3, the controller 4 and the electric drive telescopic mechanism are electrically connected.

[0027] When in use, granular fertilizer is put into the fertilizer box 2, and the trolley is manually pushed forward and backward until it moves to the fixed-point fertilization location. The controller 4 controls the electric drive telescopic mechanism to drive the main ground plug 10 to reciprocate and retract. The main ground plug 10 reciprocates and retracts once to form a fixed-point fertilization, that is, when the main ground plug 10 is extended, it is inserted into the soil together with the auxiliary ground plug 11 and squeezes the soil to form a hole. In this process, the opening of the temporary storage tank 12 passes through the feed pipe 9, so that the fertilizer in the fertilizer box 2 can enter the temporary storage tank 12 through the discharge pipe 13, the hose and the feed pipe 9. As the main ground plug 10 retracts, the auxiliary ground plug 11 is squeezed by the soil and remains in the soil for a certain period of time. At this time, the bottom of the temporary storage groove 12 is opened, so that the fertilizer is discharged and retained in the hole. As the main ground plug 10 is further lifted, under the action of the elastic member, the auxiliary ground plug 11 is recombined with the main ground plug 10, and the fixed-point fertilization is completed. The main ground plug 10 and the auxiliary ground plug 11 are driven by the electric drive telescopic mechanism to reciprocate and retract, so that the fixed-point drilling and fertilization can be completed in one go. Compared with manual fixed-point fertilization, it saves physical strength and improves efficiency.

[0028] The electric-driven telescopic mechanism includes an electric-driven rotating mechanism, a main crankshaft 16, and a connecting rod 17. The front and rear parts of the trolley are each rotatably connected to the main crankshaft 16. The shaft neck direction of the main crankshaft 16 is horizontally arranged front to back. The electric-driven rotating mechanism is connected to the end shaft of the main crankshaft 16 to drive the main crankshaft 16 to rotate. The shaft neck position of the connecting rod 17 of the main crankshaft 16 is rotatably connected to multiple connecting rods 17 from front to back in sequence. Each of the connecting rods 17 is respectively hinged to the left and right axial ends of the main ground plug 10. The electric-driven rotating mechanism is electrically connected to the controller 4.

[0029] Furthermore, the main crankshaft 16 can be driven to rotate by the electric drive rotating mechanism, thereby driving the main ground plug 10 to slide axially back and forth along the guide tube 8 through the connecting rod 17.

[0030] The main crankshaft 16 includes a crank arm 18 and a connecting rod arm 19. The front and rear parts of the main crankshaft 16 are the crank arms 18. The adjacent parts of the crank arms 18 of the front and rear parts of the main crankshaft 16 are cylindrical structures parallel to each other. The opposite parts of the crank arms 18 of the front and rear parts of the main crankshaft 16 are coaxial shaft structures. The crank arms 18 of the front and rear parts of the main crankshaft 16 are slidably connected with the connecting rod arm 19 through the cylindrical structure. The connecting rod arm 19 is a "U"-shaped structure, and the front and rear parts are each threadedly connected with a group of locking nuts 20. The middle part of the connecting arm 19 is the connecting rod journal of the main crankshaft 16. The opposite parts of the crank arms 18 of the front and rear parts of the main crankshaft 16 are the end shafts of the main crankshaft 16. The locking nuts 20 of the front and rear parts of the connecting arm 19 are respectively locked on the cylinder of the crank arm 18. The axial two ends of the structure can be adjusted by adjusting the position of the tightening nut 20 on the connecting rod arm 19 and clamping the crank arm 18 at the same time to adjust the distance between the middle part of the connecting rod arm 19 and the axial structure of the crank arm 18. A plurality of paired and separated limit plates 21 are fixed to the middle part of the connecting arm 19. The limit plates 21 are used to limit the position of the connecting rod 17. The connecting rod 17 includes a connecting rod body 22 and a clamp 23. A screw 24 is fixed to the left and right parts of the connecting rod body 22. The screw 24 is inserted through and connected with the left and right parts of the clamp 23, and a locking nut 25 is threadedly connected. The locking nut 25 tightens the clamp 23. The clamp 23 and the connecting rod body 22 are jointly inserted into the middle part of the crank arm 18 to realize the rotational connection of the connecting rod 17 relative to the connecting rod journal of the main crankshaft 16.

[0031] Furthermore, by manually rotating the locking nut 20, the position of the connecting rod arm 19 relative to the crank arm 18 can be adjusted, that is, the size of the reciprocating telescopic sliding stroke of the main ground plug 10 can be adjusted, thereby changing the depth of the hole formed after the main ground plug 10 is inserted into the soil. By removing the locking nut 25, the number of connecting rods 17 rotatably connected to the crank arm 18 can be changed, thereby adjusting the density of fertilization to meet the needs of different plants. For crops with smaller plant spacing, the fertilization efficiency can be improved by increasing the density of fertilization. For crops with larger plant spacing, unnecessary fertilizer waste can be reduced by reducing the density of fertilization.

[0032] The trolley includes a frame 26, the two main crankshafts 16 are rotatably connected to the frame 26, and the opposite parts of the two support frames 7 are respectively fixed with horizontal support cylinders 27, the two support cylinders 27 are coaxial, and are coaxially arranged with the end shafts of the two main crankshafts 16, and the front and rear parts of the frame 26 are respectively fixed with a rotary damper 41, the end shaft of the main crankshaft 16 is inserted and connected with the rotor of the rotary damper 41, the support frame 7 and the support cylinder 27 are respectively rotatably connected to the outer wall of the rotary damper 41, and the two support cylinders 27 are respectively coaxially fixed with worm wheels 28, and the front and rear parts of the frame 26 are respectively rotatably connected with a horizontal worm 29, the two worms 29 are respectively meshed with the two worm wheels 28, and the two worms 29 are respectively coaxially fixed with hand wheels 30, and when the worm 29 rotates forward and reversely, it can drive the support frame 7 to swing left and right through the worm wheel 28 to adjust the angle with the frame 26.

[0033] Furthermore, by manually rotating the hand wheel 30 forward and reverse, the meshing of the worm 29 and the worm wheel 28 can be used to adjust the angle of the support frame 7 relative to the frame 26, thereby changing the angle of the guide tube 8 relative to the ground, that is, changing the angle and position of the main ground plug 10 inserted into the ground to adapt to different crop requirements.

[0034] The electric drive rotating mechanism includes a reduction motor 31, a vertical reduction motor 31 is fixed in the middle of the frame 26, a horizontal No. 1 transmission shaft 32 is rotatably connected in the middle of the frame 26, the No. 1 transmission shaft 32 is transmission-connected with the rotating shaft of the reduction motor 31 through the meshing of bevel gears, a No. 1 main friction disc 33 is coaxially fixed to the front of the No. 1 transmission shaft 32, and a No. 2 main friction disc 34 is coaxially fixed to the rear, the adjacent end shaft parts of the two main crankshafts 16 are axially slidably connected with a No. 1 transmission cylinder 35, a No. 1 auxiliary friction disc 36 is coaxially fixed to the No. 1 transmission cylinder 35 at the front of the frame 26, and a No. 2 auxiliary friction disc 37 is coaxially fixed to the No. 1 transmission cylinder 35 at the rear of the frame 26, and a No. 1 auxiliary friction disc 36 is coaxially fixed to the main crankshaft 16 to which it is slidably connected, and a No. 2 auxiliary friction disc 37 is coaxially fixed to the No. 1 transmission cylinder 35 at the rear of the frame 26. Compression spring 38, the No. 1 auxiliary friction disc 36 and the No. 2 auxiliary friction disc 37 have a tendency to approach each other under the elastic repulsive force of the No. 1 compression spring 38, the No. 1 auxiliary friction disc 36 and the No. 2 auxiliary friction disc 37 can respectively fit and frictionally contact with the No. 1 main friction disc 33 and the No. 2 main friction disc 34, the No. 1 auxiliary friction disc 36 and the No. 2 auxiliary friction disc 37 are respectively fixed with a No. 1 permanent magnet 39 on the opposite parts, and the No. 1 electromagnet 40 is respectively fixed on the adjacent parts of the two support frames 7, the reduction motor 31 and the No. 1 electromagnet 40 are electrically connected to the controller 4, the No. 1 permanent magnet 39 and the No. 1 electromagnet 40 correspond to each other front and back, and when the No. 1 electromagnet 40 is passed with current in different directions, it can magnetically absorb and repel the No. 1 permanent magnet 39 under the action of magnetic force, so that the No. 1 transmission cylinder 35 slides forward and backward along the main crankshaft 16.

[0035] Furthermore, when fertilizing, the reduction motor 31 is controlled to rotate continuously, and the No. 1 electromagnet 40 and the No. 1 permanent magnet 39 are magnetically attracted to each other. At this time, the No. 1 auxiliary friction disc 36 and the No. 2 auxiliary friction disc 37 are respectively away from the No. 1 main friction disc 33 and the No. 2 main friction disc 34, and the resistance of the rotary damper 41 is used to limit the position of the main crankshaft 16 relative to the frame 26 to avoid its accidental rotation. When it is necessary to control the corresponding main ground plug 10 to extend or retract, the corresponding No. 1 electromagnet 40 is controlled to change the direction of the current, thereby the corresponding No. 1 permanent magnet 39 is Magnetic repulsion, so that under the combined action of magnetic force and the elastic repulsion of the No. 1 compression spring 38, the No. 1 auxiliary friction disk 36 is in friction contact with the No. 1 main friction disk 33, or the No. 2 auxiliary friction disk 37 is in friction contact with the No. 2 main friction disk 34. Then, by utilizing the rotation of the reduction motor 31, the corresponding main crankshaft 16 is driven to rotate through the bevel gear and the No. 1 transmission shaft 32. When the corresponding main crankshaft 16 needs to stop rotating, the corresponding No. 1 electromagnet 40 is controlled to change the current direction to restore the magnetic attraction to the No. 1 permanent magnet 39.

The front distance sensor 54 and the rear distance sensor 55 are electrically connected to the controller 4 respectively, and the front and rear parts of the frame 26 are each installed with a group of identification mechanisms, and the identification mechanisms include infrared The transmitter 64 and the infrared receiver 65 are arranged relative to each other in the front-to-back direction and fixed to the frame 26. The infrared transmitter 64 and the infrared receiver 65 are electrically connected to the controller 4 respectively. The infrared transmitter 64 and the infrared receiver 65 correspond to the main crankshaft 16 respectively in the front-to-back direction. The outer wall of the auxiliary ground plug 11 is provided with a recessed knurled pattern 66. A handle 67 is fixed to the front of the frame 26. A button switch 68 is fixed to the handle 67. The button switch 68 is electrically connected to the controller 4.

[0037] Furthermore, when in use, the device is placed in the gap between rows of crops, such as between rows of corn plants or wheat, and the dual-axis reduction motor is controlled to rotate continuously. Initially, the second electromagnet 50 and the second permanent magnet 49 magnetically repel each other, and at this time, the second auxiliary friction disc 37 and the second main friction disc 34 are in contact with each other, so that the third transmission shaft 44 is driven to rotate through the second transmission shaft 43, that is, the rolling friction between the roller 52 and the ground is used to realize the self-propelled walking of the cart. In the process of self-propelled walking, the front The distance sensor 54 and the rear distance sensor 55 measure the distance to the left and right respectively. When the measured data is small, it means that the crops are nearby. Then the controller 4 automatically controls the second electromagnet 50 to magnetically attract the second permanent magnet 49, so that the second main friction disc 34 is separated from the second auxiliary friction disc 37, that is, the cart stops walking by itself. Then, according to the distance measurement result, the corresponding first electromagnet 40 is controlled to magnetically repel the first permanent magnet 39, that is, the corresponding main crankshaft 16 is rotated (the front distance sensor 54 When the measurement result is small, the main crankshaft 16 at the front of the frame 26 rotates, and when the measurement result of the rear distance sensor 55 is small, the main crankshaft 16 at the rear of the frame 26 rotates). When the main crankshaft 16 rotates, it can interfere with the infrared transmitter 64, so that the infrared receiver 65 cannot receive the signal. Whenever this phenomenon occurs, it indicates that the corresponding main crankshaft 16 has rotated one circle, that is, the extension and contraction of the main ground plug 10 is completed, that is, the drilling and fertilization are completed. Then the main crankshaft 16 corresponds to the first electromagnet 40 to restore the magnetic attraction to the first permanent magnet 39, and then the second electromagnet 50 magnetically repels the second permanent magnet 49, so as to achieve self-propelled walking again, until the next distance measurement result meets the rotation requirement of the main crankshaft 16. In this cycle, the electric drive self-propelled walking and automatic fixed-point fertilization are realized, which greatly reduces the complexity of human control and improves the fertilization efficiency. It only needs to hold the handcart by hand and use the universal wheel 53 to grasp the direction. The button switch 68 is used to control whether the dual-axis reduction motor rotates.

[0038] A vertical No. 4 transmission shaft 56 is rotatably connected to the bottom of the fertilizer box 2.

The end shafts of the two secondary crankshafts 58 are transmission-connected to the upper part of the No. 4 transmission shaft 56 through the meshing of bevel gears. The bevel gears that transmission-connect the No. 4 transmission shaft 56 and the secondary crankshaft 58 are located in the shell 57.

[0039] Furthermore, during the rotation process, the dual-axis reduction motor can drive the secondary crankshaft 58 to rotate continuously through the No. 1 transmission shaft 32, the bevel gear and the No. 4 transmission shaft 56, thereby stirring the fertilizer in the fertilizer box 2 to facilitate its falling along the discharge pipe 13.

[0040] A manual stop valve 59 is installed in the middle of each discharge pipe 13, and an adjustment cylinder 60 is coaxially threadedly connected to the upper part of the main ground plug 10. The relative position of the adjustment cylinder 60 relative to the opening of the temporary storage tank 12 can be changed when the adjustment cylinder 60 rotates forwards and backwards.

[0041] Furthermore, the manual stop valve 59 can be used to control whether the discharge pipe 13 discharges fertilizer, thereby adapting to the number of connecting rods 17 installed on the main crankshaft 16, and by manually rotating the adjusting cylinder 60, the size of the opening of the temporary storage tank 12 can be adjusted, thereby adjusting the length of time that the opening of the temporary storage tank 12 is connected to the feed pipe 9 during the extension and retraction of the main ground plug 10, and then controlling the amount of fertilizer entering the temporary storage tank 12, thereby controlling the fertilization effect.

[0042] The elastic member is an elastic rope 61, and the auxiliary ground plug 11 includes a light rod 62 fixed at the bottom, and the light rod 62 is axially slidingly connected to the main ground plug 10. The elastic rope 61 is fixed to the axial end of the upper part of the light rod 62, and the other end of the elastic rope 61 is fixed to the main ground plug 10.
