[0015] Compared with the prior art, the remarkable advantages of the present invention are:

[0016] First: In the present invention, the soil mixed with fertilizer is transported between the first sieve and the second sieve by a conveying component. After being screened, the soil falls into the interiors of two soil spreading boxes, so that the soil is spread on the top of the film in two times. Sowing work is carried out by a sowing component, so that the seeds are sown in the middle of the two-time spreading of the soil. The soil can completely cover the seeds. By the rotation of the auger rod, the push rod is pushed upward, so that the two second sieves move upward. As a result, the bottom ends of the two first sieves move towards the adjacent side, and the gap between the top ends of the two second sieves becomes smaller. The crushing saw teeth on the side walls of the two second sieves crush the soil to avoid soil caking; the problem that the existing soil cannot cover the seeds is solved.

[0017] Second: In the present invention, when the push rod moves downward, by utilizing the elasticity of the contraction spring, the extension rod is pulled into the interior of the receiving rod, shortening the lengths of the extension rod and the receiving rod, facilitating the outward expansion of the bottom ends of the two first sieves, so that the unfiltered soil falls between the two second sieves, facilitating the crushing of the soil when the second sieves move upward.

[0018] Third: In the present invention, the gathering block facilitates the seeds to enter the interior of the conveying cylinder, facilitating the conveyance of the seeds. The seeds are centrally processed by the gathering box, facilitating the outward spreading of the seeds through the folding pipe. The drainage block guides the soil to move towards the drainage plate. By setting the drainage plate to be inclined, the rolling speed of the soil is increased, facilitating the spreading of the soil.

[0019] Fourth: In the present invention, by the rotation of the installed turntable, the pressing plate pushes the driving plate to move outward together with the pushing plate. Under the influence of the compression spring, the driving plate returns to its original position. Therefore, the driving plate can drive the mounting frame and the drainage plate to move left and right together, making the pressing roller press the film more evenly. The drainage plate drives the folding pipe to slide left and right through the linkage rod, increasing the distribution range of the soil and the seeds. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention provides an intelligent integrated operation vehicle for agricultural fertilization, sowing, film laying and pesticide spraying by improvement. The technical solution of the present invention is as follows:

[0032] Such as Figures 1 - 7As shown in the figure, an intelligent integrated operation vehicle for agricultural fertilization, sowing, film laying and pesticide spraying includes a framework, and the framework includes two positioning frames 11. A plurality of connecting frames 12 are fixedly installed on the side wall surfaces of the two positioning frames 11 that are close to each other. The positions of the two positioning frames 11 are strengthened through the connecting frames 12 to ensure the stable positions of the positioning frames 11. Two connecting rods 13 are fixedly installed on the bottom wall surface of the positioning frame 11 close to the top, and four connecting rods 13 are also fixedly installed on the bottom wall surface of the positioning frame 11 close to the bottom. Guide rollers 16 are rotatably installed on the side wall surfaces of the two connecting rods 13 in the same horizontal direction that are close to each other. Two mounting rods 19 are fixedly installed on the bottom wall surface of the positioning frame 11 close to the top. Mounting turntables 17 are rotatably installed on the side wall surfaces of the two mounting rods 19 that are close to each other. A receiving roll is clamped on the side wall surfaces of the two mounting turntables 17 that are close to each other. A film 18 is wound on the side wall of the receiving roll. One end of the film 18 far from the mounting turntable 17 on the framework is attached to the side walls of the three guide rollers 16. By fixing one end of the film 18 far from the mounting turntable 17 and then pushing the operation vehicle to move, the film 18 can be laid at the set position. A conveying assembly is arranged outside the positioning frame 11. The conveying assembly includes a receiving frame 26 fixedly installed on the rear side wall surfaces of the two positioning frames 11. Universal wheels 15 are fixedly installed on both the receiving frame 26 and the bottom wall surface of the positioning frame 11 close to the bottom. The universal wheels 15 facilitate the staff to push the operation vehicle to move. A housing 21 is fixedly installed on the front side wall surface inside the receiving frame 26. Driving rollers 22 are rotatably installed at both the upper and lower ends of the inner side wall of the housing 21. A servo motor is fixedly installed on the outer side wall of the receiving frame 26. The output end of the servo motor is fixedly connected to the adjacent driving roller 22. A transmission belt 23 is sleeved on the side walls of the two driving rollers 22. A plurality of transmission strips 24 are fixedly installed at equal intervals on the side wall of the transmission belt 23. A slantingly distributed conveying frame 27 is fixedly installed at the top of the front side wall surface of the housing 21. The conveying frame 27 is communicated with the inside of the housing 21. A guide plate 25 is fixedly installed on the inner bottom wall surface of the receiving frame 26. The soil is guided to the side wall of the transmission strip 24 through the guide plate 25;Inside the positioning frame 11, there is a flow splitting component. The flow splitting component includes two soil spreading boxes 31. On the side wall surfaces of the two soil spreading boxes 31 that are close to each other, a seed sowing box 32 is fixedly installed. On the top wall surfaces of the two soil spreading boxes 31, a flow splitting box 33 in an inverted "Y" shape is fixedly installed. The top end of the flow splitting box 33 is fixedly connected to the bottom end of the conveying frame 27. Outside the seed sowing box 32, there is a seed sowing component extending into the seed sowing box 32. The seed sowing component includes a receiving box 41 fixedly installed on the side wall of the positioning frame 11. On the side wall surface of the positioning frame 11 away from the receiving box 41, a driving motor 42 is fixedly installed. On the side wall of the receiving box 41, a conveying cylinder 43 penetrating through the inside of the seed sowing box 32 is fixedly installed. Inside the conveying cylinder 43, there is a screw rod 44. The output end of the driving motor 42 is fixedly connected to the screw rod 44. At equal intervals at the bottom end side wall of the conveying cylinder 43, a plurality of seed sowing holes 49 are opened. Inside the flow splitting box 33, there is a crushing component. The crushing component includes two first sieves 51. The top ends of the two first sieves 51 are respectively rotatably installed on the front and rear sides of the inner side wall of the flow splitting box 33. On the bottom wall surfaces of the two first sieves 51, second sieves 52 are rotatably installed. The bottom ends of the two second sieves 52 are rotatably connected together by hinges; Put the seeds into the inside of the receiving box 41, and then the seeds will flow into the inside of the conveying cylinder 43. Through the rotation of the output end of the driving motor 42, the seeds are conveyed. Finally, the seeds flow out through the seed sowing holes 49 and are sprinkled on the soil. After mixing the soil and fertilizer, put them into the accommodating frame 26, and then through the rotation of the transmission roller 22, the soil is sent into the conveying frame 27 along with the transmission strip 24. The soil is collected by the first sieve 51 and the second sieve 52. The first sieve 51 and the second sieve 52 screen the soil, and the soil is evenly divided into the two soil spreading boxes 31. Finally, it is sprinkled on the top of the film 18. Since the seed sowing box 32 is arranged between the two soil spreading boxes 31, during the movement of the working vehicle, the soil in the soil spreading box 31 closer to the rear side will be sprinkled on the surface of the film 18 first, and then the seeds are sprinkled on the soil. The soil in the soil spreading box 31 closer to the front side will cover the seeds, which is convenient for the seeds to germinate.;

[0033] Such as Figures 2 - 6As shown, multiple ejector rods 54 are provided at the bottom end of the second sieve 52. The bottom end of the ejector rod 54 slidably penetrates through the top of the seeding box 32 and the conveying cylinder 43 and fits against the side wall of the auger rod 44. By the rotation of the auger rod 44, the ejector rod 54 is pushed upward, causing the two second sieves 52 to move upward. As a result, the bottom ends of the two first sieves 51 move toward the adjacent side, and the gap between the top ends of the two second sieves 52 becomes smaller. Thus, the two second sieves 52 can squeeze the soil and crush the agglomerated soil, enabling the soil to fully cover the seeds. A plurality of staggered crushing saw teeth 58 are fixedly installed at equal intervals on the adjacent side wall surfaces of the two second sieves 52. The staggered crushing saw teeth 58 on the side walls of the two second sieves 52 facilitate the cutting and crushing of the soil. Two connecting blocks 53 are fixedly installed on the bottom wall surface of the two first sieves 51 and the front and rear side wall surfaces inside the shunt box 33. A receiving rod 56 is rotatably installed on the adjacent side wall surface of the two connecting blocks 53 on the first sieve 51. An extension rod 55 is rotatably installed on the adjacent side wall surface of the two connecting blocks 53 on the shunt box 33. The top ends of the two extension rods 55 are respectively slidably installed inside the two receiving rods 56. A compression spring 57 is fixedly connected inside each of the two receiving rods 56. The bottom ends of the two compression springs 57 are fixedly connected to the side wall of the extension rod 55. When the ejector rod 54 moves downward, by utilizing the elasticity of the compression spring 57, the extension rod 55 is pulled into the receiving rod 56, shortening the lengths of the extension rod 55 and the receiving rod 56, facilitating the outward expansion of the bottom ends of the two first sieves 51, enabling the unfiltered soil to fall between the two second sieves 52, and enabling the second sieves 52 to crush the soil when moving upward.

[0034] As Figures 1 - 7 shown, a converging block 46 is fixedly installed on the inner side wall of the receiving box 41. The top wall surface of the converging block 46 is inclined to align with the conveying cylinder 43. The converging block 46 facilitates the conveyance of seeds into the interior of the conveying cylinder 43 and facilitates the conveyance of seeds. A baffle 45 is fixedly installed at the top end of the side wall of the conveying cylinder 43 close to the receiving box 41. The baffle 45 restricts the seeds entering the interior of the conveying cylinder 43, preventing the seeds from filling the interior of the conveying cylinder 43, leaving a gap at the top end part of the interior of the conveying cylinder 43, and avoiding the situation where the interior of the conveying cylinder 43 is filled with seeds, resulting in the inability of the conveying cylinder 43 to push the ejector rod 54 up and down. A converging box 47 is fixedly installed on the bottom wall surface of the seeding box 32. A folding tube 48 is fixedly installed on the bottom wall surface of the converging box 47. The converging box 47 centrally processes the seeds, facilitating the outward spreading of the seeds through the folding tube 48.

[0035] As Figures 1 - 7As shown in the figure, sliding grooves 35 are formed on the side walls of both soil spreading boxes 31. An inclined drainage plate 36 is slidably installed inside the sliding grooves 35. Drainage blocks 34 are fixedly installed on the inner bottom wall surfaces of both soil spreading boxes 31. The drainage blocks 34 guide the soil to move towards the drainage plate 36. By setting the drainage plate 36 in an inclined shape, the rolling speed of the soil is increased, facilitating the spreading of the soil. Linking rods 39 are fixedly installed on the bottom wall surfaces of both drainage plates 36, and the bottom ends of the linking rods 39 are installed on the side walls of the folding pipe 48.

[0036] As Figures 1 - 7 shown in the figure, a pressing component is arranged between the two positioning frames 11. The pressing component includes two mounting frames 71. A plurality of pressing rollers 72 are rotatably installed on the side walls of the two mounting frames 71 close to each other. A plurality of rolling balls 73 are rotatably installed at equal intervals on the side walls of the pressing rollers 72. The side walls of the rolling balls 73 are in contact with the side wall of the film 18. Two positioning rods 74 are fixedly installed on the top wall surface of the positioning frame 11 near the bottom. A linking frame 75 is fixedly installed on the top wall surfaces of the two mounting frames 71. The top end of the linking frame 75 is slidably installed inside the two positioning rods 74. A second connecting rod 76 is fixedly installed on the top wall surface of the linking frame 75. By making the side walls of the rolling balls 73 in contact with the side wall of the film 18, the rolling balls 73 press the film 18 onto the ground. A driving component is arranged outside the positioning frame 11. The driving component includes a driving plate 61. A sliding rod 62 slidably penetrates through the inside of the driving plate 61. One end of the sliding rod 62 is fixedly installed on the side wall of the adjacent mounting rod 19. A compression spring 63 that is in contact with the side wall of the driving plate 61 is sleeved inside the sliding rod 62. A plurality of circumferentially distributed pressing plates 65 are fixedly installed on the side wall of the mounting turntable 17 close to the driving plate 61. A pushing plate 66 aligned with the pressing plates 65 is fixedly installed on the side wall of the driving plate 61. A through groove 64 aligned with the pressing plates 65 is formed on the side wall of the mounting rod 19. The top end of the second connecting rod 76 is fixedly installed on the side wall of the driving plate 61. A first connecting rod 68 is fixedly installed on the side wall of the driving plate 61. A pushing frame 67 is fixedly installed on the bottom wall surface of the first connecting rod 68. The bottom end of the pushing frame 67 is fixedly installed on the top wall surfaces of both drainage plates 36. By rotating the mounting turntable 17, the pressing plates 65 push the driving plate 61 to move outward together with the pushing plate 66. The driving plate 61 returns to its original position under the influence of the compression spring 63. Therefore, the driving plate 61 can drive the mounting frame 71 and the drainage plate 36 to move left and right together, making the pressing rollers 72 press the film 18 more evenly. The drainage plate 36 drives the folding pipe 48 to slide left and right together through the linking rod 39, increasing the distribution range of the soil and seeds.

[0037] The specific working method is as follows: Put the seeds and the soil mixed with fertilizer into the inside of the receiving box 41 and the accommodating frame 26 respectively. Fix one end of the film 18 far from the mounting turntable 17, then push the working vehicle to move, lay the film 18 at the predetermined position. By fitting the rolling ball 73 with the side wall of the film 18, the rolling ball 73 presses the film 18 tightly on the ground. Through the rotation of the driving roller 22, the soil is sent into the inside of the conveying frame 27 along with the transmission strip 24. Through the rotation of the auger rod 44, the ejector rod 54 is pushed upward to move the two second sieves 52 upward. As a result, the bottom ends of the two first sieves 51 move towards the adjacent side, and the gap between the tops of the two second sieves 52 becomes smaller. Thus, the two second sieves 52 can extrude the soil, crush the caked soil, crush the soil, and evenly distribute the soil into the two soil spreading boxes 31. The seeds in the receiving box 41 will flow into the inside of the conveying cylinder 43. Through the rotation of the output end of the driving motor 42, the seeds are conveyed, and the seeds flow out through the sowing holes 49 and are sprinkled on the soil. Since the sowing box 32 is arranged between the two soil spreading boxes 31, during the movement of the working vehicle, the soil in the soil spreading box 31 closer to the rear side will be first sprinkled on the surface of the film 18, and then the seeds are sprinkled on the soil. The soil in the soil spreading box 31 closer to the front side will cover the seeds, so that the humidity and temperature of the environment around the seeds are maintained stable, and the adverse effects of humidity and temperature changes on the seeds can be reduced.
