Description

Technical Field

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

[0002] Agricultural fertilization refers to the process of adding appropriate amounts of fertilizers to farmland during the growth of crops, based on factors such as soil nutrient status, crop needs, and growth environment, in order to supplement or improve soil nutrient status, promote healthy growth of crops, and increase crop yield and quality. Fertilization is a vital part of agricultural production, and has a direct and significant impact on the growth, development, and yield of crops. At present, when fertilizing agricultural plants, fertilizers are usually placed directly into storage boxes, which are installed on tractors, and the fertilizers are fed through control mechanisms to complete fertilization.

[0003] The prior art has the following defects:

[0004] 1. When the storage box is directly installed on the tractor for unloading, only fertilizer can be unloaded and fertilized. Some crops such as corn and soybeans need to be fertilized when sowing. Since the existing fertilization equipment can only fertilize, it is difficult to combine fertilization and sowing at the same time, which requires secondary operation and wastes time;

[0005] 2. The existing fertilization equipment is used to control the sowing and fertilization areas by the tractor's driving speed, that is, the tractor's driving speed needs to be controlled during sowing, and the speed needs to be controlled according to the sowing position to adjust the distance between the seeds and the fertilizer during fertilization. It needs to be controlled twice to adjust the distance between the seeds and the fertilizer, which is inconvenient to operate.

[0006] 3. Directly introduce the fertilizer into the internal storage of the material box. The discharge port is relatively small because the amount of material discharged needs to be controlled. Some compound fertilizers will clump after entering moisture. If they are poured directly into the material box without being crushed, the discharge port will easily be blocked, making it impossible to discharge fertilizer. Summary of the invention

[0015] Specifically, an L-shaped structure is formed between the two cross bars and the baffle plate, and an L-shaped structure is formed between the two baffle plates and the bidirectional screw rod.

When the cam plate 415 rotates to a vertical position, the contact plate 413 is also pushed to the highest point. At this time, the connecting shaft 412 drives the two push plates 403 to rise and move into the inside of the material box 402. When the push plates 403 rise, the seeds and fertilizers in the two material boxes 402 are respectively loaded into the inside of the trough 414. When the tops of the two push plates 403 are flush with the surface of the lower feeding plate 411, the fertilizer and seeds in the trough 414 are The seeds and fertilizers will fall onto the unloading plate 411 and finally fall into the inside of the receiving box 501. The seeds and fertilizers are discharged into the field from the unloading pipe 503 respectively. When the cam plate 415 rotates to the opposite side of the contact plate 413, the contact plate 413 drives the push plate 403 to descend. At this time, the bottom of the push plate 403 abuts against the protective frame 404 to prevent it from falling. After the push plate 403 descends, it loads the materials again, and so on. The speed of loading and unloading is adjusted according to the speed of the second motor 406, and the controllable The landing point of seeds and fertilizers, when the amount of fertilizers and seeds needs to be adjusted, the connecting column 702 can be placed inside the trough 414 to change the volume of the trough 414. When connecting the connecting column 702, the plug rod 703 can be plugged into the plug hole 704 at the bottom of the previous connecting column 702, and the connecting column 702 and the fixed column 701 are also connected by the plug rod 703 and the plug hole 704. The more connecting columns 702 are placed, the smaller the volume of the trough 414, and vice versa.

[0043] Specifically, Figure 2 , Figure 3 and Figure 8As shown, the adjustment mechanism 6 includes two mounting seats 604, the two receiving boxes 501 are fixedly connected with the mounting seats 604, the two brackets 504 are fixedly connected with cross bars 603, the two cross bars 603 are fixedly connected with two baffles 602, the two baffles 602 are rotatably connected with bidirectional screw rods 601, and the two ends of the bidirectional screw rods 601 are respectively threadedly connected with the two mounting seats 604; the two cross bars 603 and the baffles 602 form an L-shaped structure, and the two baffles 602 and the bidirectional screw rods 601 form an L-shaped structure; when it is necessary to change the fertilizer When adjusting the distance between the material and the seeds, it is necessary to adjust the distance between the two discharge pipes 503. When adjusting, the bidirectional screw rod 601 on the baffle 602 can be rotated. When the bidirectional screw rod 601 is rotated, the mounting seat 604 is pulled, and the two mounting seats 604 move relative to or away from each other. After the two mounting seats 604 move relative to each other, the two receiving boxes 501 are driven to move relative to each other. However, the unloading plate 411 still drops into the inside of the receiving box 501 when unloading the material. Only the unloading position of the discharge pipe 503 is changed, which is convenient for adjusting the distance between the seeds and the fertilizer according to the needs to avoid excessive burning of the seeds and fertilizers.

[0044] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the rolling mechanism 3 includes a connecting bucket 301 and a rolling bucket 302, wherein the top of one of the material boxes 402 is fixedly connected to a connecting bucket 301 with a funnel-shaped structure, the top of the connecting bucket 301 is fixedly connected to a rolling bucket 302 with a bottom opening, the rolling bucket 302 is fixedly connected to a top frame 303, a first motor 304 is installed on the top frame 303, the output end of the first motor 304 is horizontally fixedly connected to two connecting rods 305, and the opposite ends of the two connecting rods 305 are fixedly connected to pressure rollers 306; when planting and fertilizing, the compound fertilizer should be poured into the inside of the rolling bucket 302 first, and the first motor 304 is started to realize the rotation of the two pressure rollers 306 on the top of the rolling bucket 302, and the compound fertilizer poured into the rolling bucket 302 will be pushed by the pressure rollers 306. The unclumped compound fertilizer will fall from the holes on the rolling bucket 302 into the interior of the connecting bucket 301. Compared with the traditional rotational connection between the pressing roller 306 and the connecting rod 305, the compound fertilizer can only be rolled, and the rolled compound fertilizer remains in place, which cannot achieve a pushing effect. However, the pressing roller 306 and the connecting rod 305 are fixedly connected, and the rolled compound fertilizer will be pushed when the pressing roller 306 passes again, achieving a pushing effect, and finally falls into the material box 402 at the bottom of the connecting bucket 301 for storage. Due to the gap between the pressing roller 306 and the rolling bucket 302, the compound fertilizer agglomerated on the rolling bucket 302 can be crushed when the pressing roller 306 rotates, which is convenient for the compound fertilizer to fall into the internal storage of the hopper 402, and it is also beneficial for the compound fertilizer to be discharged from the discharge port 410 to avoid blockage.

[0045] When the present invention is used, first, when planting and fertilizing, the compound fertilizer must be poured into the inside of the rolling bucket 302, and the first motor 304 is started to realize that the two pressing rollers 306 rotate at the top of the rolling bucket 302, and the compound fertilizer poured into the rolling bucket 302 will be pushed by the pressing rollers 306. Compared with the traditional rotation connection between the pressing rollers 306 and the connecting rods 305, the compound fertilizer can only be rolled, and the rolled compound fertilizer is still in place, which cannot achieve a pushing effect. However, the rolling compound fertilizer after the pressing rollers 306 and the connecting rods 305 are fixedly connected. The material will be pushed by the pressing roller 306 when it passes again, achieving a pushing effect. The unclumped compound fertilizer will fall from the holes on the rolling bucket 302 into the inside of the connecting bucket 301, and finally fall into the inside of the material box 402 at the bottom of the connecting bucket 301 for storage. Since there is a gap between the pressing roller 306 and the rolling bucket 302, the compound fertilizer agglomerated on the rolling bucket 302 can be crushed when the pressing roller 306 rotates, which is convenient for the compound fertilizer to fall into the internal storage of the hopper 402, and it is also beneficial for the compound fertilizer to be discharged from the discharge port 410 to avoid blockage.

[0046] Then, after the fertilizer reaches the inside of one of the material boxes 402, the seeds need to be added into the inside of the material box 402 at the bottom of the cover plate 408. When the seeds are also added into the inside of the material box 402, the tractor body 1 is driven to the field to start planting and fertilizing, and the second motor 406 is started to realize that the drive shaft 407 drives the cam plate 415 to rotate. Since the structure of the cam plate 415 is cam-shaped, when the drive shaft 407 rotates, the cam plate 415 intermittently pushes the two contact plates 413 on the connecting shaft 412. When the cam plate 415 rotates to a vertical position, the contact plate 413 is also pushed to the highest point. At this time, the connecting shaft 412 drives the two push plates 403 to rise and move into the inside of the material box 402. When the push plates 403 rise, the seeds and fertilizers in the two material boxes 402 are respectively loaded into the inside of the trough 414. When the tops of the two push plates 403 are flush with the surface of the lower plate 411, the fertilizer and seeds in the trough 414 are The seeds and fertilizers will fall onto the unloading plate 411 and finally fall into the inside of the receiving box 501. The seeds and fertilizers are discharged into the field from the unloading pipe 503 respectively. When the cam plate 415 rotates to the opposite side of the contact plate 413, the contact plate 413 drives the push plate 403 to descend. At this time, the bottom of the push plate 403 abuts against the protective frame 404 to prevent it from falling. After the push plate 403 descends, it loads the materials again, and so on. The speed of loading and unloading is adjusted according to the speed of the second motor 406, and the controllable The landing point of seeds and fertilizers, when the amount of fertilizers and seeds needs to be adjusted, a connecting column 702 can be placed inside the trough 414 to change the volume of the trough 414. When connecting the connecting column 702, the plug rod 703 can be plugged into the socket 704 at the bottom of the previous connecting column 702, and the connecting column 702 and the fixed column 701 are also connected by the plug rod 703 and the socket 704. The more connecting columns 702 are placed, the smaller the volume of the trough 414, and vice versa.

[0047] Finally, when the distance between the fertilizer and the seeds needs to be changed, the distance between the two discharge pipes 503 needs to be adjusted. When adjusting, the bidirectional screw rod 601 on the baffle 602 can be rotated. When the bidirectional screw rod 601 is rotated, the mounting seat 604 is pulled, and the two mounting seats 604 move relative to or away from each other. After the two mounting seats 604 move relative to each other, the two receiving boxes 501 are driven to move relative to each other. However, the unloading plate 411 still drops into the inside of the receiving box 501 when unloading. Only the unloading position of the discharge pipe 503 is changed, which is convenient for adjusting the distance between the seeds and the fertilizer according to needs to avoid excessive burning of the seeds and fertilizers.
