Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and in particular to a uniform fertilization device for agricultural planting. Background Art

[0002] In the process of crop production, it is necessary to promote its growth by applying fertilizers, and the growth of crops is divided into multiple cycles. Different fertilizers need to be applied in different cycles, such as potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer. At the same time, according to the characteristics of fertilizers, they are also divided into solid fertilizers and liquid fertilizers. In order to improve the absorption rate of fertilizers and reduce soil eutrophication during normal fertilization, the best way is to apply fertilizers directly into the soil. Existing fertilizer applicators often apply them on the soil surface. In the later stage of crop growth, the roots are deep and the absorption rate of fertilizers on the soil surface is low.

[0003] When fertilizing by insertion, the existing insertion fertilizing device is generally divided into a driving mechanism and an insertion component. During normal fertilization, the driving mechanism is always running. When the insertion component is inserted to a specified depth, the insertion component will also move forward under the influence of the driving mechanism, resulting in a groove being actually inserted. At this time, the groove needs to be filled. At the same time, as the fertilization depth continues to increase, the groove becomes deeper and deeper, which will cause a lot of increase in the movement energy loss of the equipment. At the same time, under the influence of the groove, the soil around the crops will become loose, affecting the growth of crops. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. An embodiment of the present invention provides a uniform fertilization device for agricultural planting to solve the technical problem that when the existing fertilization device is performing inserted fertilization, the tractor cannot move, otherwise the inserted tube will plow the roots of the plants.

[0005] The embodiment of the present invention adopts the following technical solution: a uniform fertilization device for agricultural planting, including a tractor, a fertilization mechanism for fertilizing, and a gap control mechanism for controlling the fertilization mechanism to move synchronously with the tractor, the fertilization mechanism including a regulating insertion component and a connecting component, the connecting component including a plurality of connecting disks, a rolling belt is provided on the outer surface of the connecting disk, and an electric telescopic rod is provided between adjacent rotating disks.

[0006] Furthermore, the regulating insertion component includes a connecting shaft, which passes through the connecting disk and is rotatably and slidably connected to the connecting disk. A free drive motor is provided at one end of the connecting shaft, and the other end of the connecting shaft is connected to the connecting disk through an adjusting cylinder. A plurality of pushing blocks are provided on the connecting shaft, and the pushing blocks are located in the connecting disk. A fertilizer insertion tube is provided in each of the connecting disks, and a reset spring is provided between the fertilizer insertion tube and the connecting disk. The upper end of the fertilizer insertion tube is made of soft and retractable material.

[0007] Furthermore, the outer surface of the pushing block is a curved surface.

[0008] Furthermore, the connecting disk is rotationally connected to the rolling belt.

[0009] Furthermore, a feed box is provided at the end of the tractor, and the feed box is connected to the fertilization insertion tube through a feed pipe.

[0010] Further, the gap control mechanism includes a traction component and a controllable limit component, the traction component includes a connecting frame, the connecting frame is connected to the traction machine, a slider is slidably arranged in the connecting frame, a limit groove is provided at one end of the slider, a traction frame is arranged beside the slider, the end of the traction frame is rotatably connected to an auxiliary frame, the auxiliary frame is rotatably connected to the connecting shaft, a resetter is arranged on one side of the inner surface of the connecting frame, and a reset electric control rod is arranged on the inner surface of the connecting frame.

[0011] Furthermore, balls are provided at the upper and lower ends of the sliding block.

[0012] Furthermore, the controllable limit assembly includes a connecting motor, a bidirectional threaded screw is provided at the end of the connecting motor, a screw rack is provided on the bidirectional threaded screw, a sliding control block is slidably provided on the screw rack, a locking bolt is provided between the sliding control block and the screw rack, a limiting block is rotatably provided on the connecting rack, the limiting block is located in the limiting groove, a slot is provided on one side of the upper end of the limiting block, and a limiting rod is provided in the slot, connecting reset spring racks are provided at both ends of the limiting rod, a resistance block is provided above the limiting rod, and an opening for the rotation of the limiting block is provided on the connecting rack.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] First, through the fertilization mechanism, the device can achieve the effect of fixed distance when fertilizing, so as to achieve the effect of interval fertilization, and the specific fertilization interval is set according to the movement distance of the tractor, and in the process of fertilization, due to the different growth cycles of different plants, the root depths of the plants are different at this time. At this time, the fertilization insertion tube can be inserted into different soil depths through the fertilization mechanism, so that the fertilizer can be better absorbed. At this time, compared with the insertion type and spraying fertilization, spraying fertilization is directly sprayed on the soil surface, and then waits for the fertilizer to penetrate into the soil and then be absorbed by the roots. The environmental influence on the soil surface leads to poor fertilizer absorption effect, while directly acting on the soil can improve the absorption rate of fertilizer and reduce the loss of fertilizer caused by eutrophication of the soil surface and soil erosion;

[0015] Secondly, through the coordinated use of the gap control mechanism and the fertilizing mechanism, when the fertilizing mechanism is fertilizing the soil, the fertilizing insertion tube is located in the soil. If no additional gap control mechanism is provided, the fertilizing insertion tube will directly follow the movement of the tractor, resulting in a plowing state. At this time, through the gap control mechanism, when fertilizing, the tractor is still moving, but the structure in the gap control mechanism changes its motion state, so that the movement of the tractor does not drive the fertilizing mechanism to move, so that the fertilizing mechanism has enough time to fertilize. When the fertilization is completed, the fertilizing mechanism will continue to move with the tractor, thereby achieving the effect that the fertilizing mechanism intermittently follows the movement of the tractor;

[0016] To sum up, the present fertilization device first changes the way of fertilization from surface fertilization to inserted fertilization inside the soil, and during the insertion process, the specific insertion depth can be adjusted according to demand, and in the process of using the traction machine to pull the fertilization mechanism, when the fertilization mechanism is inserted into the soil, the movement of the traction machine will not drive the fertilization mechanism to move. When the fertilization mechanism is not fertilizing, the fertilization mechanism will follow the traction machine to move, thereby achieving an intermittent following effect.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Combine the following Figures 1 to 7 As shown, an embodiment of the present invention provides a uniform fertilization device for agricultural planting, including a tractor 1, a fertilization mechanism 2 for fertilizing, and a gap control mechanism 3 for controlling the fertilization mechanism 2 to move synchronously with the tractor 1. The fertilization mechanism 2 includes a regulating insertion component and a connecting component, and the connecting component includes a plurality of connecting disks 22. A rolling belt 23 is provided on the outer surface of the connecting disk 22, and an electric telescopic rod 24 is provided between adjacent rotating disks.

[0033] Specifically, the regulating insertion component includes a connecting shaft 26, which passes through the connecting disk 22, and the connecting shaft 26 and the connecting disk 22 are rotatably and slidably connected. A free drive motor 21 is provided at one end of the connecting shaft 26, and the other end of the connecting shaft 26 is connected to the connecting disk 22 through an adjusting cylinder. A plurality of pushing blocks 25 are provided on the connecting shaft 26, and the pushing blocks 25 are located in the connecting disk 22. A fertilizer insertion tube 28 is provided in each of the connecting disks 22, and a reset spring 27 is provided between the fertilizer insertion tube 28 and the connecting disk 22. The upper end of the fertilizer insertion tube 28 is made of soft and retractable material.

[0034] Specifically, the outer surface of the pushing block 25 is a curved surface.

[0035] During operation, since the push block 25 is a curved surface and the lower portion of the fertilizer insertion tube 28 is made of a hard material, when the push block 25 rotates, it can contact the fertilizer insertion tube 28, so that the fertilizer insertion tube 28 is inserted into the soil.

[0036] Specifically, the connecting disk 22 is rotationally connected to the rolling belt 23 .

[0037] During operation, when the connecting disc 22 moves with the traction machine 1, the connecting disc 22 does not rotate, but the rolling belt 23 rotates.

[0038] Specifically, a feed box 4 is provided at the end of the tractor 1 , and the feed box 4 is connected to the fertilizer insertion tube 28 via a feed pipe 41 .

[0039] Specifically, the gap control mechanism 3 includes a traction component and a controllable limit component. The traction component includes a connecting frame 31, which is connected to the traction machine 1. A slider 39 is slidably arranged in the connecting frame 31. A limit groove is provided at one end of the slider 39. A traction frame 38 is arranged beside the slider 39. The end of the traction frame 38 is rotatably connected to an auxiliary frame, and the auxiliary frame is rotatably connected to the connecting shaft 26. A resetter 33 is arranged on one side of the inner surface of the connecting frame 31, and a reset electric control rod 32 is arranged on the inner surface of the connecting frame 31.

[0040] Specifically, balls are disposed at the upper and lower ends of the slider 39 .

[0041] During operation, since the sliding block 39 is additionally provided with balls, the sliding friction coefficient between the sliding block 39 and the connecting frame 31 is smaller, so that the sliding is facilitated.

[0042] Specifically, the controllable limit assembly includes a connecting motor 37, a bidirectional threaded screw 36 is provided at the end of the connecting motor 37, a screw rack 35 is provided on the bidirectional threaded screw 36, a sliding control block 34 is slidably provided on the screw rack 35, a locking bolt is provided between the sliding control block 34 and the screw rack 35, a limiting block 310 is rotatably provided on the connecting frame 31, the limiting block 310 is located in the limiting groove, a slot is provided on one side of the upper end of the limiting block 310, and a limiting rod 313 is provided in the slot, connecting reset spring racks 314 are provided at both ends of the limiting rod 313, a resistance block 312 is provided above the limiting rod 313, and an opening for the rotation of the limiting block 310 is provided on the connecting frame 31.

[0043] Working principle: At this time, first adjust the positions of the connecting shaft 26 and the sliding control block 34 in turn according to the required fertilization depth and fertilization gap. When adjusting the connecting shaft 26, the specific position of the connecting shaft 26 is adjusted by adjusting the cylinder. At this time, an eccentric axis is formed between the connecting disk 22 and the connecting shaft 26. The eccentric gap difference is the position of the connecting shaft 26 after adjustment. Therefore, when the connecting shaft 26 rotates and drives the pushing block 25 to rotate, an eccentric movement will occur at this time. At this time, when the pushing block 25 drives the fertilizer insertion tube 28 to be inserted into the tube, the insertion depth can be controlled. When adjusting the sliding control block 34, first loosen the locking bolt, and then adjust the sliding The relative position of the sliding control block 34 and the screw rod frame 35 is then fixed by the locking bolt. Since the actual movable distance of the screw rod frame 35 remains unchanged, the positions of the sliding control block 34 and the abutment block 312 remain unchanged, and the positions of the sliding control block 34 and the abutment block 312 control the fertilization gap. Therefore, when the position of the sliding control block 34 is adjusted, the effect of adjusting the fertilization gap can be achieved. When fertilizing, the traction machine 1 drives the connecting plate 22 to move through the connecting frame 31, the traction frame 38 and the auxiliary frame. When moving, the rolling belt 23 on the connecting plate 22 rolls. At this time, the connecting motor 37 on the connecting frame 31 is constantly rotating, thereby bringing The two-way threaded screw 36 rotates, and the rotation of the two-way threaded screw 36 drives the screw rack 35 to move. The movement of the screw rack 35 drives the sliding control block 34 to move. At this time, the sliding control block 34 moves to a certain position and contacts the contact block 312. The movement of the contact block 312 drives the limit rod 313 to move. At this time, the limit rod 313 no longer restricts the limit block 310, that is, it is disengaged from the lock of the slider 39. At this time, the slider 39 will move, while the sliding control block 34 continues to move. The slider 39 moves and disengages from the resetter 33 to send a signal to control the movement of the drive motor 21. The drive motor 21 drives the connecting shaft 26 to rotate, thereby driving the push block 25 to deflect. , the push block 25 deflects and resists the fertilizer insertion tube 28 to be inserted into the soil. At this time, the tractor 1 is still moving, but the connecting plate 22 is relatively static. Therefore, the movement of the tractor 1 will not cause the fertilizer insertion tube 28 to plow the land. When the slider 39 resists the reset electric control rod 32, the drive motor 21 reverses, and the push block 25 no longer resists the fertilizer insertion tube 28. The fertilizer insertion tube 28 is reset under the action of the reset spring 27, and the slider 39 is reset under the action of the reset electric control rod 32. At this time, the screw rod frame 35 is reset under the action of the bidirectional threaded screw rod 36, and the limit rod 313 is reset under the action of the connection reset spring frame 314, so that the next fertilization can be carried out;

[0044] In summary, the present fertilization device first changes the method of fertilization from surface fertilization to inserted fertilization inside the soil, and during the insertion process, the specific insertion depth can be adjusted according to demand, and in the process of using the traction machine 1 to pull the fertilization mechanism 2, when the fertilization mechanism 2 is inserted into the soil, the movement of the traction machine 1 will not drive the fertilization mechanism 2 to move. When the fertilization mechanism 2 is not fertilizing, the fertilization mechanism 2 will follow the traction machine 1 to move, thereby achieving an intermittent following effect.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
