A layered fertilizer machine for soybean and corn interplanting

Abstract

The application discloses a layered fertilizer machine for soybean and corn compound planting and relates to the technical field of agricultural machinery. The layered fertilizer machine comprises a rack, a supporting frame fixed on the rack, a winding wheel placed in a groove on the top of the supporting frame, a fixing sleeve fixed on one side of the supporting frame, a rotating block rotatably connected to the fixing sleeve through a stabilizing frame, a rectangular rod inserted into the rotating block and penetrating into the center shaft of the winding wheel at one end, and a fixing rod inserted into the fixing sleeve and provided with a friction plate at the end. When the winding wheel rotates too fast and inertia overruns, the friction resistance of the winding wheel can be automatically increased to inhibit excessive unwinding, avoid the sagging and piling of the drip irrigation belt and the winding of the drip irrigation belt around the machine, and ensure the straight and orderly laying of the drip irrigation belt. When the rotating speed of the winding wheel is too slow and the drip irrigation belt is excessively pulled with too large tension, the winding wheel can be automatically provided with auxiliary rotating thrust to reduce the unwinding resistance and prevent the drip irrigation belt from being pulled, broken and ruptured.

Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a stratified fertilizer applicator for soybean-corn intercropping. Background Technology

[0002] In the soybean-corn intercropping model, the root systems of corn and soybean are at different depths and have significantly different nutrient requirements. The stratified fertilizer applicator is the core equipment for achieving precision fertilization. Its core function is to apply corn-specific fertilizer to the deep soil and soybean-specific fertilizer to the shallow soil, matching the root distribution of the two crops, avoiding nutrient competition, improving fertilizer utilization, and adapting to the agronomic needs of intercropping.

[0003] Inner Mongolia is mostly an arid and semi-arid dryland farming area with dry soil and scarce moisture. Fertilizers need soil moisture to dissolve and be absorbed by crops. Therefore, when applying fertilizers in layers, drip irrigation tape needs to be laid simultaneously to supplement soil moisture and achieve synergistic water and fertilizer application. At present, drip irrigation tape is mostly laid using a roller structure. The drip irrigation tape is wound on the roller, and a pressing mechanism is set under the frame. The pressing mechanism moves with the frame and presses the drip irrigation tape against the ground. The friction between the drip irrigation tape and the ground pulls the roller to rotate passively, completing the unwinding and laying of the drip irrigation tape.

[0004] Existing drip irrigation tape reels lack any reverse braking torque balancing mechanism, relying solely on the tension of the drip irrigation tape to drive rotation. During operation, fluctuations in the frame speed, ground undulations, or changes in the coefficient of friction can all cause the reels to over-rotate due to inertia, resulting in excessive release of the drip irrigation tape. This can cause the tape to become loose, wrinkled, or piled up, or even entangle in machine parts, leading to machine shutdown. Furthermore, the lack of reverse braking torque makes it impossible to balance the unwinding tension, making the drip irrigation tape prone to breakage when tension suddenly increases. This can lead to interruptions in the drip irrigation tape laying operation, thereby affecting the overall planting efficiency. Summary of the Invention

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1-4 and Figure 8 This is the first embodiment of the present invention. This embodiment provides a stratified fertilizer applicator for soybean-corn intercropping. The stratified fertilizer applicator for soybean-corn intercropping includes a frame 1 and a support frame 2 fixed on the frame 1. A roller 3 is placed inside a groove at the top of the support frame 2. A positioning leg is fixed on the support frame 2. A pressure roller is provided at the bottom of the positioning leg. The drip irrigation tape passes through the positioning leg to the ground and is pressed by the pressure roller. When the frame 1 moves, the drip irrigation tape can be laid. The frame 1 is equipped with a fertilizer applicator mechanism and is connected to the suspension mechanism of the tractor through a mounting frame. It can move with the tractor in the field to perform fertilizer application operations. This is the prior art. This solution will not be described in detail here, and those skilled in the art can clearly understand the working principle.

[0033] Both ends of the outer side of the reel 3 are equipped with blocking rings. One blocking ring is fixed to the reel 3 with screws, and the other blocking ring is fixed to the reel 3. The blocking rings can be removed and the drip irrigation tape can be put on the outside of the central shaft of the reel 3. After the central shaft of the reel 3 is placed inside the groove at the top of the support frame 2, the pressure block is fixed to the top of the support frame 2 with screws to prevent the reel 3 from separating from the support frame 2.

[0034] The fixed sleeve 4 is fixed to one side of the support frame 2. The rotating block 5 is rotatably connected to the fixed sleeve 4 through the stabilizer. The rectangular rod 6 is inserted into the rotating block 5. The rectangular rod 6 can move axially within the rotating block 5 and has a large friction with the inside of the rotating block 5. After the winding wheel 3 is placed, one end of the rectangular rod 6 is inserted into the central shaft of the winding wheel 3. At this time, the winding wheel 3 can be connected to the rotating block 5, so that the rotating block 5 will rotate with the winding wheel 3.

[0035] Multiple fixing rods 7 are inserted into the fixing sleeve 4 in a ring, and friction plates 8 are fixed to the ends of the fixing rods 7. Multiple friction strips are fixed to one side of the friction plate 8. The friction strips are made of flexible rubber. When the roller 3 over-rotates due to inertia and releases too much drip irrigation tape, the fixing rods 7 will drive the friction plate 8 to approach the rotating block 5. The friction strips will increase the resistance of the rotating block 5 and the roller 3 when rotating, thereby reducing the rotation speed of the roller 3, suppressing excessive unwinding, avoiding loose accumulation and wrinkling of the drip irrigation tape, and ensuring that the drip irrigation tape is laid straight and orderly.

[0036] The guide rail 9 is fixed on one side of the support frame 2. The guide rail 9 is vertical at the bottom and arc-shaped at the top, and is coaxial with the roller 3. The support column 10 is located inside the guide rail 9 and can move along the trajectory of the guide rail 9.

[0037] The push plate 11 is rotatably connected to the outside of the support column 10. The push plate 11 is located below the blocking ring on the outside of the roll 3. The friction block 12 is hinged to the top of the push plate 11. When the speed of the roll 3 is too slow and the drip irrigation tape is excessively stretched, the support column 10 will drive the push plate 11 to move upward, so that the push plate 11 drives the friction block 12 to contact the bottom of the blocking ring. At the same time, the support column 10 will move along the arc-shaped guide rail 9. At this time, the push plate 11 will push the roll 3 to rotate through the friction of the friction block 12, which will apply an auxiliary rotational thrust to the roll 3, reduce the unwinding resistance, and prevent the drip irrigation tape from being stretched and broken.

[0038] The rotating unit 13 is located on the outside of the fixed sleeve 4 and is used to drive the fixed rod 7 to move. The pushing unit 14 is located below the support column 10 and is used to drive the support column 10 to move upward.

[0039] The trigger unit 15 is located on one side of the support frame 2 and is connected to the push unit 14. The trigger unit 15 is used to detect the tension of the drip irrigation tape. If the tension of the drip irrigation tape is small and the unwinding is too fast, the rotating unit 13 will drive the fixed rod 7 to move. If the tension of the drip irrigation tape is too large, the push unit 14 will drive the support column 10 to move upward.

[0040] Example 2, refer to Figures 2-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, it also includes a rotating unit 13, which includes a rotating ring 131 rotatably connected to the outside of the fixed sleeve 4, a guide shaft 132 fixed to the end of the fixed rod 7, a guide groove 1311 on the rotating ring 131, the guide groove 1311 being arc-shaped, the guide shaft 132 sliding within the guide groove 1311, and a rotating rod 133 fixed to the bottom of the rotating ring 131. When the rotating rod 133 rotates, it will drive the rotating ring 131 to rotate, causing the guide shaft 132 to slide within the guide groove 1311. The two work together to drive the fixed rod 7 to move. A counterweight is fixed at the lower end. The counterweight is relatively heavy and is used to apply a vertical force to the rotating rod 133, so that the rotating rod 133 can always remain vertical when no force is applied.

[0042] The pushing unit 14 includes a push rod 141 rotatably connected to the outside of the support column 10, a connecting block 142 hinged to the bottom of the push rod 141, a fixed column 143 fixed to the bottom of the connecting block 142, and a rotating sleeve 144 rotatably connected to the support frame 2. The fixed column 143 has a spiral groove 1431, and a fixed shaft 145 is fixed inside the rotating sleeve 144 and slides inside the spiral groove 1431. When the rotating sleeve 144 rotates, it will drive the fixed shaft 145 to slide inside the spiral groove 1431. Through the cooperation of the two, the fixed column 143 is driven to move upward. The fixed column 143 pushes the connecting block 142 and the push rod 141 to move upward, thereby allowing the push rod 141 to push the support column 10 to move upward.

[0043] A tension spring 146 is fixed to the bottom of the fixed column 143. The bottom of the tension spring 146 is fixed to the inner wall of the rotating sleeve 144. When the rotating sleeve 144 loses its rotational thrust, the fixed column 143 can be pulled downward to reset by the tension spring 146.

[0044] The triggering unit 15 includes a guide wheel 151 located on one side of the support frame 2, and a connecting frame 152 rotatably connected to the outside of the guide wheel 151. The connecting frame 152 is U-shaped. When the drip irrigation tape is inserted into the positioning leg, it first passes between the guide wheel 151 and the connecting frame 152. The positioning rod 153 is fixed on one side of the connecting frame 152, and one end passes through the support frame 2. The spring 154 is sleeved on the outside of the positioning rod 153, and both ends are fixed to the support frame 2 and the connecting frame 152 respectively.

[0045] When the drip irrigation tape is unwound, it will contact the guide wheel 151. When the drip irrigation tape is straightened due to unwinding, it will exert a pushing force on the guide wheel 151. At this time, the guide wheel 151 will drive the connecting frame 152 to stretch the spring 154. When the drip irrigation tape is unwound under normal tension, the spring 154 will be in a semi-stretched state. If the reel 3 over-rotates due to inertia and releases too much drip irrigation tape, the pushing force of the drip irrigation tape on the guide wheel 151 will decrease. At this time, the spring 154 will pull the connecting frame 152 to move towards the support frame 2, and cause the connecting frame 152 to drive the positioning rod 153 to move, and can reduce the rotation speed of the reel 3.

[0046] If the speed of the reel 3 is too slow, causing the drip irrigation tape to be stretched too much, the thrust of the drip irrigation tape on the guide wheel 151 will increase. At this time, the guide wheel 151 will move away from the support frame 2, and push the connecting frame 152 and the positioning rod 153 to move, and increase the speed of the reel 3.

[0047] It also includes a connecting unit 16, which includes a pressing rod 161 fixed to the end of the positioning rod 153. The upper end of the pressing rod 161 is L-shaped. The force-bearing rod 162 is fixed to the outside of the rotating sleeve 144 and contacts the end of the pressing rod 161. When the guide wheel 151 moves away from the support frame 2, it will drive the pressing rod 161 to push the force-bearing rod 162 to rotate through the connecting frame 152 and the positioning rod 153, and cause the force-bearing rod 162 to drive the rotating sleeve 144 to rotate.

[0048] A connecting rod 163 is fixed to one side of the extrusion rod 161. The force-bearing block 164 is fixed to one side of the rotating rod 133 and contacts the end of the connecting rod 163. The guide post 165 is fixed to one side of the support frame 2 and is movably connected to the connecting rod 163. When the connecting frame 152 moves toward the support frame 2, it will drive the connecting rod 163 to extrude the force-bearing block 164 through the positioning rod 153, and cause the force-bearing block 164 to drive the rotating rod 133 to rotate.

[0049] Example 3, referring to Figures 5-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, a plug rod 71 is inserted into the fixed rod 7, and multiple slots 72 that cooperate with the plug rod 71 are opened on the outside of the rotating block 5. The connecting shaft 73 is fixed to one end of the plug rod 71, and the rotating rod 74 is hinged to one side of the fixed rod 7 through a hinge rod and is movably connected to the outside of the connecting shaft 73. The rotating rod 74 is L-shaped.

[0051] The hinge rod includes a pivot, a torsion spring, and a support rod. The support rod is fixed to the fixed rod 7, the pivot is fixed to the rotating rod 74, and is rotatably connected to the support rod. The two ends of the torsion spring are fixed to the support rod and the pivot, respectively. The torsion spring applies a torsional force to the pivot and the rotating rod 74, so that the rotating rod 74 always remains in its current state and can be reset after rotation.

[0052] If the drip irrigation tape is unwound too much and the connecting frame 152 moves to the maximum extent in the direction of the support frame 2, the end of the rotating rod 74 will contact the fixed sleeve 4 and rotate under the directional thrust of the fixed sleeve 4. At this time, the other end of the rotating rod 74 will push the insertion rod 71 to move, so that the insertion rod 71 is inserted into the slot 72. The two work together to completely lock the rotating block 5 and stop the reel 3 from rotating. This avoids the drip irrigation tape being unwound too much due to the excessive rotation of the reel 3, which would cause the drip irrigation tape to get tangled on the machine parts and cause the machine to stop.

[0053] There are multiple friction blocks 12, which are evenly distributed in an arc on the push plate 11. The stop block 111 is fixed to the push plate 11 and contacts one side of the friction block 12 to restrict the rotation of the friction block 12. When the push plate 11 pushes the roller 3 upward to rotate, the friction block 12 is restricted by the stop block 111 and will not rotate, thus being able to fit tightly with the roller 3. When the push plate 11 moves downward, the friction block 12 will rotate to one side under friction and will not fit tightly with the roller 3, thus preventing the push plate 11 from hindering the rotation of the roller 3 when it resets.

[0054] The guide rod 112 is fixed to the bottom of the push plate 11, the stabilizing shaft 113 is fixed to one side of the guide rod 112, and the guide plate 114 is fixed to the bottom of the guide rail 9. The shape of the guide plate 114 is the same as that of the guide rail 9. The movement trajectory of the stabilizing shaft 113 inside the guide plate 114 is consistent with the movement trajectory of the support column 10 inside the guide rail 9. This is used to support the angle of the push plate 11 and prevent the angle of the push plate 11 from not being able to fit tightly with the winding wheel 3.

[0055] Limiting plates are fixed on the outer side of the support column 10 and on both sides of the guide rail 9 to prevent the support column 10 from separating from the guide rail 9.

[0056] When in use, if the reel 3 over-rotates due to inertia and excessively releases the drip irrigation tape, the thrust of the drip irrigation tape on the guide wheel 151 will decrease. At this time, the spring 154 will pull the connecting frame 152 to move towards the support frame 2, and the connecting frame 152 will drive the positioning rod 153 to move. The positioning rod 153 will drive the connecting rod 163 to squeeze the force block 164, and the force block 164 will drive the rotating rod 133 to rotate. When the rotating rod 133 rotates, it will drive the rotating ring 131 to rotate, causing the guide shaft 132 to slide in the guide groove 1311. The two work together to drive the fixed rod 7 to move. The fixed rod 7 will drive the friction plate 8 to approach the rotating block 5, and increase the resistance of the rotating block 5 and the reel 3 when rotating through the friction strip, thereby reducing the rotation speed of the reel 3, suppressing excessive unwinding, avoiding the drip irrigation tape from accumulating loosely, wrinkling and tangling around the machine, and ensuring that the drip irrigation tape is laid flat and orderly.

[0057] When the speed of the three rollers is too slow and the drip irrigation tape is excessively stretched, the thrust of the drip irrigation tape on the guide roller 151 will increase. At this time, the guide roller 151 will move away from the support frame 2, and push the connecting frame 152 and the positioning rod 153 to move. The positioning rod 153 drives the squeezing rod 161 to push the force rod 162 to rotate, and the force rod 162 drives the rotating sleeve 144 to rotate. When the rotating sleeve 144 rotates, it will drive the fixed shaft 145 to slide in the spiral groove 1431. Through the cooperation of the two, the fixed column 143 is driven to move towards the support frame 2. The upward movement is achieved by the fixed column 143 pushing the connecting block 142 and the push rod 141 upward, which in turn pushes the support column 10 upward. The support column 10 will drive the push plate 11 upward, causing the push plate 11 to drive the friction block 12 to contact the bottom of the blocking ring. At the same time, the support column 10 will move along the arc-shaped guide rail 9. At this time, the push plate 11 will drive the roller 3 to rotate through the friction of the friction block 12, applying an auxiliary rotational thrust to the roller 3, which can reduce the unwinding resistance and prevent the drip irrigation tape from being stretched and broken.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
