Description

Technical Field

[0001] The present invention relates to the technical field of land fertilization, in particular to a ridging and strip application machine for organic fertilizer under film. Background Art

[0002] In agricultural production, fertilization is required before or after planting crops to improve the survival rate and yield of crops. Farmyard manure, namely organic fertilizer, such as pure sheep manure, pure chicken manure, chemical fertilizer mixed with sheep manure, chemical fertilizer mixed with chicken manure, organic fertilizer mixed with biological bacterial fertilizer, etc. The traditional application method of farmyard manure is mainly surface spreading, and then the fertilizer is mixed with the soil through agricultural machinery ploughing. The fertilization amount per mu can reach 1 - several cubic meters. However, such an application method of farmyard manure has the following problems: the fertilization accuracy is insufficient. It is difficult to control the distribution position or depth of the fertilizer in the soil by traditional spreading combined with agricultural machinery ploughing. For example, when transplanting peppers, it is best to apply organic fertilizer and biological bacterial fertilizer to a depth of 10 - 15 cm from the ground surface. However, the existing agricultural machinery ploughing is difficult to achieve precise positioning, resulting in reduced fertilizer utilization rate. And for full - spread application, the amount of fertilizer used is large. If precise strip application or hole application is carried out, usually fertilization is carried out at multiple points simultaneously. Therefore, a large area needs to be covered for a single operation, that is, a large - capacity fertilizer storage device is required. However, for the high - efficiency organic fertilizer obtained by mixing pure sheep manure, pure chicken manure and chemical fertilizer after secondary composting and sieving, its particles are fine and sticky. When stored in a large - capacity fertilizer storage device for fertilization, it is easy to cause the discharge channel to be blocked due to friction, humidity or particle aggregation, and the fertilizer cannot be discharged smoothly from the storage device.

[0025] like Figures 1-7As shown in the figure, the ridging and organic fertilizer band applicator under the film includes a rotary tillage and film laying machine for rotary tillage and film laying of the land. Specifically, the rotary tillage and film laying machine can adopt the existing structures described in CN219894064U "A Rotary Tillage and Film Laying Machine" or CN205694112U "A Wide-width Adjustable Rotary Tillage and Film Laying Machine for Fruit Tree Rows", and is suspended on a tractor for rotary tillage and film laying of the land. A rotary tillage and film laying machine beam 11 is provided on the rotary tillage and film laying machine. On the rotary tillage and film laying machine beam 11, a fertilizer box 2 is provided. The fertilizer box 2 can be directly installed above the film laying machine by using a frame, and the fertilizer box 2 adopts a trapezoidal structure with a wider upper part and a narrower lower part, which is beneficial to the storage and falling of organic fertilizer. A first mixer 22 is provided in the fertilizer box 2 for mixing the organic fertilizer stored in the fertilizer box 2 to prevent it from solidifying in the fertilizer box 2 and unable to be fertilized smoothly. The first mixer 22 includes a first rotating shaft 221 horizontally arranged in the fertilizer box.

The circumferential direction of the first rotating shaft 221 is provided with winding wheels 222 arranged along the length direction of the first rotating shaft 221, and the winding wheels 222 are used to mix the organic fertilizer stored in the fertilizer box 2. In addition, to ensure that the fertilizer at each fertilizer outlet 21 is not blocked, a stirring rod 223 corresponding to each fertilizer outlet 21 one by one is installed on the first rotating shaft 221. The stirring rod 223 is perpendicular to the first rotating shaft 221 and stirs the fertilizer above the fertilizer outlet 21 during the rotation of the first rotating shaft 221 to make it loose so that it can fall into the fertilizer box 31 below the fertilizer box 2 along the fertilizer outlet 21;The lower fertilizer box 31 and the fertilization box 2 can be detachably connected by bolts or latches, or can be directly welded into an integral structure. An upper fertilizer inlet hole 33 aligned with the lower fertilizer hole 21 is provided on the top of the lower fertilizer box 31. A second mixer 32 is provided in the lower fertilizer box 31. The second rotating shaft 321 of the second mixer 32 is transversely arranged in the lower fertilizer box 31 to stir the fertilizer in the lower fertilizer box 31 that has not yet been transported to the soil entering device 4, so as to avoid the fertilizer being solidified into blocks due to long-term accumulation and unable to be fertilized. The second rotating shaft 321 of the second mixer 32 is transversely arranged in the lower fertilizer box 31, and both ends of the second rotating shaft 321 pass through the lower fertilizer box 31 and are rotatably connected to the lower fertilizer box 31, and are installed on the rotary tillage and film laying integrated machine body through a bearing seat. Specifically, the second rotating shaft 321 can be adjusted according to the second rotating shaft 321. The corresponding frame is arranged on the rotary tillage and film laying integrated machine body, and the second rotating shaft 321 extends out of one end of the lower fertilizer box 31 and is transmission connected with the driving mechanism 6, and the second rotating shaft 321 is driven to rotate by the driving mechanism 6. The second rotating shaft 321 is also provided with a winch 222, and the winch 222 is arranged on the second rotating shaft 321 along the length direction of the second rotating shaft 321 to rotate with the second rotating shaft 321 to stir the fertilizer stored in the lower fertilizer box 31. A lower fertilizer outlet hole 34 is opened at the bottom of the lower fertilizer box 31, and a lower fertilizer pipe 35 is provided at each lower fertilizer outlet hole 34. The lower fertilizer pipe 35 and the lower fertilizer outlet hole 34 can be flange-connected or directly welded to the lower fertilizer box 31. The lower fertilizer pipe 35 can be a cylindrical pipe or a square pipe, but in order to facilitate the fertilizer to be able to flow smoothly In order to facilitate downward flow, the lower fertilizer pipe 35 adopts a funnel shape that is wide at the top and narrow at the bottom for the best effect, so that the fertilizer can quickly enter the soil-entering device 4 connected to the lower fertilizer pipe 35 under the action of gravity and the squeezing action of the lower fertilizer pipe 35. The soil-entering device 4 includes a soil-entering steel pipe 41 vertically arranged on the cross bar 12, and the soil-entering steel pipe 41 is sequentially arranged under each lower fertilizer outlet pipe and is connected to the lower fertilizer outlet hole 34 through a hose 351. The hose 351 can adopt an existing PVC telescopic pipe or a telescopic corrugated pipe, so that when the cross bar 12 drives the soil-entering steel pipe 41 to move up and down, the connection between the soil-entering steel pipe 41 and the lower fertilizer pipe 35 will not be broken, and the telescopic mechanism connected to the cross bar 12 drives the cross bar 12 to move up and down, thereby driving all soil-entering devices connected to the cross bar 12. The soil steel pipe 41 moves up and down and is inserted into the soil to be fertilized for fertilizer application. The telescopic mechanism can adopt an existing hydraulic telescopic rod or an electric push rod. In order to realize the synchronous movement of the left and right sides of the cross bar 12, a telescopic mechanism can be respectively provided at both ends of the cross bar 12, and controlled by the same controller. In order to facilitate the smooth insertion of the soil steel pipe 41 for fertilization, an oblique cut 42 is provided at the lower end of the soil steel pipe 41 to facilitate insertion into the soil. At the same time, the fertilizer can first fall into the soil from the shorter side of the oblique cut 42. In order to further ensure that the soil steel pipe 41 can be smoothly inserted into the soil, retaining plates 43 are also provided on both sides of the oblique cut 42. While increasing the downward shear force on the soil, it can also ensure that the soil on both sides of the oblique cut 42 of the soil steel pipe 41 will not affect the fertilizer application effect.The driving mechanism 6 that is transmission-connected to the first rotating shaft 221 and the second rotating shaft 321 can directly use a motor 62 to transmission-connect to the first rotating shaft 221 and the second rotating shaft 321. ;

[0026] The organic fertilizer strip spreading machine under the ridging film is provided with an organic fertilizer strip spreading mechanism for fertilization on the existing ridging film spreading machine, and a first mixer 22 and a second mixer 32 are respectively provided in a fertilizer box 2 for storing organic fertilizer and a fertilizer box 31 for temporarily storing organic fertilizer, so as to achieve the mixing of organic fertilizer and prevent the organic fertilizer from solidifying and clogging the fertilizer discharge channel due to friction, moisture or particle agglomeration. For the fertilizer box 2 storing a large amount of organic fertilizer, a stirring rod 223 which is perpendicular to the first rotating shaft 221 and corresponds to the fertilizer hole 21 one by one is designed on the first rotating shaft 221 of the first mixer 22, and the stirring rod 223 is used to stir the fertilizer at the fertilizer hole 21 again to prevent the fertilizer from being blocked at the fertilizer hole 21. At the same time, the oblique cut 42 of the burying steel pipe 41 is designed to facilitate the insertion into the soil, and the retaining plate 43 can prevent the soil from entering the burying steel pipe 41 during the burying process, so as to ensure that the organic fertilizer can be smoothly applied. The connection mode of the soil and the hose 351 enables the steel pipe 41 to be flexibly moved within a certain range, adapting to different terrains and working requirements, and adjusting the depth of the steel pipe 41 inserted into the soil, thereby avoiding blockage of the fertilization channel during fertilization, realizing fast and uniform fertilization, ensuring fertilization efficiency, and the fertilization depth is adjustable; in addition, when the fertilizer box is set on the film laying machine frame, the setting point of the steel pipe can be directly set on both sides of the film laying machine. While laying the film, the cross bar is controlled to drive the steel pipe to move downward to achieve fertilization. For example, the strip applicator is added to the existing three-row ridge laying machine, and steel pipes can be set on both sides of each film laying machine to form a three-film six-row ridge film strip applicator for organic fertilizer, that is, when working, three rows of film are laid at the same time, and fertilizer is applied on both sides of each row of film, for a total of six columns of fertilization points; the specific number of fertilizer pipes is set according to the actual film laying amount of the rotary tillage and film laying integrated machine to be installed.

[0027] Furthermore, in order to avoid the fertilizer pipe 35 and the hose 351 being too long, resulting in the fertilizer between the fertilizer pipe 35 and the hose 351 being blocked and unable to be normally applied, Figure 5As shown in the figure, a bending portion 322 corresponding to the lower fertilizer outlet hole 34 is provided on the second rotating shaft 321. A crankshaft ring 323 is provided on each bending portion 322, which is arranged around the top end of the bending portion 322 and rotates with the bending portion 322 as the rotating shaft. A connecting rod 324 is fixedly provided on each crankshaft ring 323 and extends vertically downward into the lower fertilizer pipe 35. A dredging spring 325 is provided at the lower end of the connecting rod 324 and extends into the soil-entering steel pipe 41 along the hose 351. By providing the bending portion 322 corresponding to the lower fertilizer outlet hole 34 on the second rotating shaft 321 and arranging the crankshaft ring 323 at the central position of the bending portion 322, and the crankshaft ring 323 is rotatably arranged at the top end of the bending portion 322. When the bending portion 322 starts to rotate with the second rotating shaft 321, the crankshaft ring 323 makes a circular motion with the second rotating shaft 321 as the center along with the bending portion 322. At the same time, since the connecting rod 324 is provided on the crankshaft ring 323 and extends vertically downward into the lower fertilizer pipe 35, the connecting rod 324 makes a reciprocating up-and-down motion in the lower fertilizer pipe 35 along with the crankshaft ring 323, thereby driving the dredging spring 325 at the lower end of the connecting rod 324 to make a reciprocating up-and-down motion in the hose 351 and the soil-entering steel pipe 41, realizing the dredging effect on the fertilizer in the lower fertilizer pipe 35, the hose 351 and the soil-entering steel pipe 41, and avoiding the problem of fertilizer blockage. Moreover, since the bending portion 322 is arranged corresponding to the lower fertilizer outlet hole 34, it can also stir the fertilizer above the lower fertilizer outlet hole 34 again, avoid its consolidation, and ensure its smooth fertilization.

[0028] To control the fertilizer in the lower fertilizer tank 31 to be discharged at a specified position, as Figure 5 shown, the upper fertilizer inlet holes 33 and the lower fertilizer outlet holes 34 are arranged staggered one by one on the lower fertilizer tank 31. The fertilizer in the lower fertilizer tank 31 is stirred by the winch 222 provided on the second rotating shaft 321, and is extruded and pushed to control it to fall from the lower fertilizer outlet hole 34, so that when the second rotating shaft 321 does not rotate, the fertilizer does not fall from the lower fertilizer outlet hole 34, realizing the control of the falling of the fertilizer in the lower fertilizer tank 31.

[0029] To facilitate adjusting the spacing of the soil-entering steel pipes 41 according to the planting requirements of crops to meet the requirements of fertilization holes with different widths, as Figure 5 、 Figure 7As shown, the buried steel pipe 41 is detachably arranged on the cross bar 12, and the position of the buried steel pipe 41 on the cross bar 12 is adjusted to meet the requirements of fertilization holes of different widths; the buried steel pipe 41 and the cross bar 12 can be connected by a pipe clamp 44 to set the buried steel pipe 41 on the cross bar 12, and a connecting hole 121 for the pipe clamp 44 to pass through is opened on the cross bar 12, and a plurality of connecting holes 121 are arranged at intervals along the length direction of the cross bar 12. In addition to the pipe clamp 44, a binding wire or a binding belt can be directly used to pass through the connecting hole 121 to bind the buried steel pipe 41 to the cross bar 12, thereby adjusting the spacing of the buried steel pipe 41; a clamping block can be arranged on the side of the above-mentioned buried steel pipe 41, and a clamping groove adapted to the clamping block is opened on the cross bar 12, and the clamping groove is arranged at intervals along the length direction of the cross bar 12, and the detachable connection between the buried steel pipe 41 and the cross bar 12 is realized by the clamping connection between the clamping block and the clamping groove.

[0030] In order to adjust the burying depth of the burying steel pipe 41, it is ensured that the burying steel pipe 41 arranged on the cross bar 12 moves up and down synchronously to achieve a uniform depth of the fertilization hole, such as Figure 7 As shown, the two ends of the cross bar 12 are respectively connected to the vertical rod 13, the vertical rod 13 is fixed to the vehicle body, and the cross bar 12 is slidably arranged on the vertical rod 13 along the length direction of the vertical rod 13; the vertical rods 13 are arranged at both ends of the cross bar 12, and the cross bar 12 is slidably arranged on the vertical rod 13 along the length direction of the vertical rod 13; specifically, a vertically arranged slide groove 131 can be opened on the vertical rod 13, and the cross bar 12 can be slidably arranged in the slide groove 131. When the telescopic mechanism drives the cross bar 12 up and down, When moving, the cross bar 12 moves up and down along the slide groove 131, and is fixed by the corresponding locking piece, thereby adjusting the burying depth of the buried steel pipe 41; a gear rack mechanism may also be provided at the connection between the vertical bar 13 and the cross bar 12, and the gear rack is driven to move, thereby driving the cross bar 12 to move up and down; a plurality of strip holes 532 matching the size of the cross bar 12 may also be provided at intervals on the vertical bar 13, and the position of the cross bar 12 inserted into the vertical bar 13 may be adjusted according to the fertilization depth.

[0031] In order to avoid that the height of the reel 222 is too large, resulting in greater resistance during the stirring process of the reel 222, and excessive squeezing force on the organic fertilizer, causing it to clump and clog the lower fertilizer hole 21 or the lower fertilizer outlet hole 34, the height of the reel 222 is 2-3 cm. After many tests, the reel 222 can not only stir the fertilizer, but also avoid greater resistance during the stirring process, and excessive squeezing force on the organic fertilizer, causing it to clump and clog the lower fertilizer hole 21 or the lower fertilizer outlet hole 34.

[0032] In order to control the amount of fertilizer and whether to apply fertilizer, Figure 4As shown in the figure, the ridging and organic fertilizer band applicator under the film further includes a gate valve mechanism 5 provided between the fertilizer application box 2 and the fertilizer feeding mechanism 3 for controlling the fertilizer feeding; the gate valve mechanism 5 includes an upper gate box piece 51 fixedly connected to the bottom of the fertilizer application box 2, a lower gate box piece 52 fixedly connected to the top of the fertilizer feeding mechanism 3, and a gate piece 53 movably arranged between the upper gate box piece 51 and the lower gate box piece 52; the upper gate box piece 51 is bolted to the lower gate box piece 52; a first through hole 511 with the same aperture as the fertilizer feeding hole 21 and aligned with the fertilizer feeding hole 21 is opened on the upper gate box piece 51, a second through hole 521 with the same aperture as the upper fertilizer feeding hole 33 and aligned with the upper fertilizer feeding hole 33 is opened on the lower gate box piece 52, a frame-shaped convex portion 522 located in the circumferential direction of the second through hole 521 is arranged on the upper surface of the lower gate box piece 52, and an opening 523 for inserting the gate piece 53 is opened at one end of the frame-shaped convex portion 522; the gate piece 53 is inserted into the frame-shaped convex portion 522 to block the first through hole 511 and the second through hole 521, and a hand-held rod 531 is arranged at one end of the gate piece 53. As Figure 1 、 Figure 4 shown in the figure, the upper gate box piece 51 is welded to the bottom of the fertilizer application box 2 and the first through hole 511 of the upper gate box piece 51 is aligned with the fertilizer feeding hole 21 of the fertilizer application box 2, the lower gate box piece 52 is welded to the top of the lower fertilizer box 31 and the second through hole 521 of the lower gate box piece 52 is aligned with the upper fertilizer feeding hole 33 of the lower fertilizer box 31, the first through hole 511 of the upper gate box piece 51 is aligned with the second through hole 521 of the lower gate box piece 52, and bolts for connection are arranged around the upper gate box piece 51 and the lower gate box piece 52 to ensure the connection stability of the upper gate box piece 51 and the lower gate box piece 52; a gate piece 53 for blocking the first through hole 511 and the second through hole 521 is movably connected between the upper gate box piece 51 and the lower gate box piece 52. To limit the insertion distance of the gate piece 53 and provide an insertion space for the gate piece 53, a frame-shaped convex portion 522 located in the circumferential direction of the second through hole 521 is arranged on the lower gate box piece 52, and an opening 523 for inserting the gate piece 53 is arranged at one end of the frame-shaped convex portion 522. The convex portion 522 can be directly welded to the lower gate box piece 52 with a wire rod or welded to the lower gate box piece 52 with a steel sheet. To facilitate controlling the movement of the gate piece 53 between the upper gate box piece 51 and the lower gate box piece 52, a hand-held rod 531 is arranged at one end of the gate piece 53, so that the operator can hold the hand-held rod 531 to control the movement of the gate piece 53. The above-mentioned hand-held rod 531 can be directly welded to the gate piece 53, or a nut can be welded on the gate piece 53, and a screw rod is used as the hand-held rod 531, and the screw rod is screwed into the nut to arrange the hand-held rod 531 on the gate piece 53; by setting the gate valve mechanism 5, the fertilizer feeding amount and the fertilizer feeding time of the fertilizer application box 2 are controlled to ensure the fertilization effect.

[0033] To further ensure that the fertilizer in the fertilizer application box 2 does not caking and block, and at the same time ensure the installation stability of the fertilizer application box 2, as Figure 1 、 Figure 3As shown in the figure, a hydraulic cylinder 14 is further provided on the beam 11 of the rotary tillage and mulching machine. The cylinder body 141 of the hydraulic cylinder 14 is arranged on the beam 11 of the rotary tillage and mulching machine. The telescopic end 142 of the hydraulic cylinder 14 is connected to the fertilizer box 2. A hinge portion 23 is provided on the side of the fertilizer box 2 away from the hydraulic cylinder 14. The hinge portion 23 includes a support rod 232 vertically arranged on the beam 11 of the rotary tillage and mulching machine and a hinge rod 231 arranged outside the fertilizer box 2. One end of the hinge rod 231 away from the fertilizer box 2 is hinged to the top end of the support rod 232. By arranging the hydraulic cylinder 14 connected to the fertilizer box 2 on the beam 11 of the rotary tillage and mulching machine, and a hinge portion 23 connected to the beam 11 of the rotary tillage and mulching machine is provided at the end of the fertilizer box 2 away from the hydraulic cylinder 14. The hinge rod 231 arranged outside the fertilizer box 2 is hinged to the support rod 232 arranged on the beam 11 of the rotary tillage and mulching machine. The telescopic end 142 of the hydraulic cylinder 14 drives the fertilizer box 2 to swing left and right, so that the fertilizer in the fertilizer box 2 shakes, ensuring that a hole-shaped shed is formed when the fertilizer naturally falls. Through the left and right swing of the fertilizer box 2 and the vibration generated during the operation of the beam 11 of the rotary tillage and mulching machine, the hole-shaped shed fertilizer collapses and falls.

[0034] To ensure the synchronous operation of the first mixer 22 and the second mixer 32 and save power consumption, as Figure 6 shown, the drive mechanism 6 includes a motor 62 arranged on the beam 11 of the rotary tillage and mulching machine and a transmission mechanism 61. The transmission mechanism 61 includes a first gear 224 fixedly connected to the end of the first rotating shaft 221, a second gear 326 fixedly connected to the end of the second rotating shaft 321, a third gear 621 fixedly connected to the output end of the motor 62, and a gear set 611 arranged on the beam 11 of the rotary tillage and mulching machine. The gear set 611 includes a gear shaft 612 fixedly connected to the bracket 143. A fourth gear 613, a fifth gear 614 and a third gear 621 rotatably connected to the gear shaft 612 are arranged at intervals on the gear shaft 612. Transmission chains 616 are provided between the fourth gear 613 and the first gear 224, between the fifth gear 614 and the second gear 326, and between the sixth gear 615 and the third gear 621. The drive mechanism 6 combines the motor 62 and the transmission mechanism 61, with a compact structure and high transmission efficiency. Through the transmission of gears and chains, the synchronous operation of the first mixer 22 and the second mixer 32 can be realized.

[0035] As Figure 1 、 Figure 5 shown, the fertilizer delivery pipe 35 is funnel-shaped. The funnel-shaped fertilizer delivery pipe 35 can increase the flow area of the organic fertilizer, reduce the risk of blockage during the fertilizer delivery process, and improve the fertilizer delivery efficiency.

[0036] In summary, when the ridging organic fertilizer band applicator is working, the motor 62 drives the first mixer 22 and the second mixer 32 to rotate through the transmission mechanism 61, stirring the organic fertilizer in the fertilizer box 2 and the fertilizer feeding box 31. The operator controls the gate valve mechanism 5 to open the fertilizer feeding channel. The organic fertilizer enters the fertilizer feeding box 31 from the fertilizer discharging hole 21 of the fertilizer box 2 through the upper fertilizer feeding hole 33, then enters the soil through the lower fertilizer discharging hole 34, the fertilizer feeding pipe 35 and the hose 351 into the soil-entering steel pipe 41. During the operation process, the telescopic mechanism can adjust the height of the cross bar 12 as needed, thereby adjusting the soil-entering depth of the soil-entering steel pipe 41. At the same time, the dredging spring 325 can dredge the fertilizer feeding pipe 35 and the soil-entering steel pipe 41 in real time to prevent blockage.
