Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment, specifically a corn fertilizer planter. Background Technology

[0002] Corn is one of the important grains grown in my country. It has a high yield and strong adaptability. Fertilization is also required when sowing to produce better corn grains.

[0003] The corn planters currently in use consist of a frame, a seeder, a furrow opener, and a hopper. The corn seeds are placed in the hopper and then pass through the seeder into the furrow opener for sowing. This type of seeder usually combines fertilization and sowing. Because corn seeds and fertilizer are prone to mixing, this can cause seed burning, which greatly reduces sowing efficiency and affects the final yield.

[0004] For example, in the case of the corn planting and fertilizing vehicle with application number CN201120164214.4, the structure involves two guide shafts tilting the corn kernels and fertilizer into a mixing channel, causing the fertilizer to come into direct contact with the seeds, which can easily lead to the seeds being burned. Utility Model Content

[0034] The following is a detailed description of this novel experimental device with reference to the accompanying drawings:

[0035] Figure 1-5 This invention discloses a corn fertilizer planter, comprising: a support frame 1, with a front wheel 11 and a rear wheel 12 respectively mounted at its front and rear ends; a towing frame 13 and a furrowing shovel 14 symmetrically arranged on both sides of the outer shell of the front wheel 11; and further comprising:

[0036] Fertilizer conveying bin 2 is located at the top front side of the support frame 1, and two sets are symmetrically arranged about the front wheel 11. The fertilizer conveying bin 2 is driven by the front wheel 11 through the first belt group 6 to achieve rotation. The fertilizer storage box 3 is connected to the upper end of the fertilizer conveying bin 2, and the conveying pipe 23 is provided at the lower end of the fertilizer conveying bin 2.

[0037] The seed conveying bin 4 is located at the rear top of the support frame 1. The seed conveying bin 4 is driven by the fertilizer conveying bin 2 via the second belt 7 to achieve rotation. The upper end of the seed conveying bin 4 is connected to the seed storage box 5, and the lower end of the seed conveying bin 4 is connected to the pipe 43. The front end of the pipe 43 is provided with a trenching shovel 15.

[0038] Working principle:

[0039] The operator first loads the required fertilizer and corn kernels into the fertilizer storage box 3 and the seed storage box 5. The operator then uses ropes to connect the trailer 13 to the rear suspension of the tractor and drives the tractor so that the front wheel 11 drives the overall support frame 1 forward to start the operation.

[0040] The front wheel 11 drives the fertilizer conveying bin 2 to rotate through the first belt group 6. At this time, the fertilizer in the fertilizer storage box 3 falls into the fertilizer conveying bin 2 and is then conveyed through the fertilizer conveying bin 2 to the conveying pipe 23. The fertilizer is then conveyed through the conveying pipe 23 to the trench where the fertilizer needs to be laid, which is dug out by the trenching shovel 14.

[0041] At the same time, the fertilizer conveying bin 2 drives the seed conveying bin 4 to rotate via the second belt 7. At this time, the seeds in the seed storage box 5 fall into the seed conveying bin 4 and are then conveyed to the pipe 43 through the seed conveying bin 4. The seeds are then conveyed to the trenches that need to be laid by the ditching shovel 15 after the seeds have been dug out.

[0042] in,

[0043] ① With the front wheel 11 as the symmetrical point, two sets of fertilizer conveying chambers 2 are set up to realize fertilization on both sides of the land, while the sowing operation is completed by the seed conveying chamber 4 in the middle. The seeds and fertilizers are completely separated to ensure that they are not mixed. The fertilizer conveying chamber 2 puts the fertilizer down on both sides of the seed channel, ensuring that the land absorbs enough fertilizer, while also further avoiding fertilizer burning the seeds, which greatly improves sowing efficiency and yield.

[0044] ② In actual use, both fertilizer storage box 3 and seed storage box 5 can be equipped with a cover at the feeding position to further prevent fertilizer and seeds from coming into contact with air and getting damp;

[0045] ③ In actual use, a soil-covering plate 16 can be added directly behind the same horizontal plane as the conveying pipe 23, and a soil-covering plate 27 can be added directly behind the same horizontal plane as the pipe 43. As the seeder of this device moves forward, the soil-covering plate 16 pushes the soil into the fertilized trench to complete the fertilizer burial, and the soil-covering plate 27 pushes the soil into the trench into which the seeds have been sown to complete the seed burial.

[0046] ④ In actual use, the trenching shovel 14 digs deeper than the trenching shovel 2 15, so that the fertilizer is about 5cm below the seed, and the distance between the conveying pipes 23 and 43 on both sides is 7-8cm.

[0047] As described in the above scheme, the structure of fertilizer conveying chamber 2 includes:

[0048] The outer shell 20 has a notch 201 at its upper end that is connected to the fertilizer storage box 3.

[0049] The material distribution plate 21 has multiple sets of inner grooves 22 evenly arranged around its axis, and can be rotatably installed inside the outer shell 20 through the output shaft 25 of the fertilizer conveying bin. The size of the inner grooves 22 is slightly smaller than that of the notch 201.

[0050] The upper end of the conveying pipe 23 is connected through the outer shell 20, and the lower outlet 24 is at the same level as the trenching shovel 14.

[0051] Working principle:

[0052] The front wheel 11 drives the fertilizer conveying bin 2 to rotate via the first belt assembly 6. At this time, the fertilizer in the fertilizer storage box 3 falls into the fertilizer conveying bin 2. This process is as follows:

[0053] Fertilizer in fertilizer storage box 3 falls into inner groove 22 through notch 201. At this time, the output shaft 25 of fertilizer conveying chamber is driven to rotate by the first belt group 6. The distribution plate 21 connected to the output shaft 25 of fertilizer conveying chamber inside the outer shell 20 rotates synchronously, so that fertilizer in inner groove 22 falls into conveying pipe 23 and then falls from the lower outlet 24 into the trench dug by trenching shovel 14, thus completing fertilization.

[0054] The fertilizer delivery chambers 2, which are symmetrically arranged on the left and right, place the fertilizer on both sides of the seed channel to ensure that the soil absorbs enough fertilizer, while also avoiding mixing with the seeds in the middle.

[0055] The multi-inner groove design on the distribution tray 21 allows fertilizer to fall into the conveying pipe 23 in batches, controlling the amount of fertilizer applied per unit area of ​​land and avoiding uneven fertilization.

[0056] As described above, the structure of the seed delivery chamber 4 includes:

[0057] The shell 40 has an inner notch 401 at its upper end that is connected to the seed storage box 5.

[0058] The seeding disc 41 has multiple sets of slots 42 evenly arranged around its axis, and is rotatably mounted inside the housing 40 via the output shaft 45 of the seed conveying chamber. The size of the slots 42 is slightly smaller than the inner notch 401.

[0059] The pipe 43 has a structure that is wider at the top and narrower at the bottom. The upper end of the pipe 43 is connected to the shell 40, and the lower port 44 is at the same level as the trenching shovel 15.

[0060] Working principle:

[0061] The fertilizer conveying bin 2 drives the seed conveying bin 4 to rotate via the second belt 7. At this time, the seeds in the seed storage box 5 fall into the seed conveying bin 4. This process is as follows:

[0062] Seeds in the seed storage box 5 fall into the slot 42 through the inner notch 401. At this time, the output shaft 45 of the seed conveying chamber is driven to rotate by the second belt 7. The seed distribution disc 41 connected to the output shaft 45 of the seed conveying chamber inside the shell 40 rotates synchronously, so that the seeds in the slot 42 fall into the pipe 43 and then fall from the lower port 44 into the trench dug by the second trenching shovel 15, thus completing the sowing.

[0063] The multi-groove design of the seeding tray 41 allows seeds to fall into the pipe 43 in batches. The structure of the pipe 43, which is wider at the top and narrower at the bottom, allows for control of the amount of seeds sown per unit area of ​​land, thus avoiding uneven distribution of seeds.

[0064] As described above, the structure of the first belt group 6 includes: a first pulley, which is fixedly installed on both sides of the rotating shaft of the front wheel 11;

[0065] The second pulley 60 is symmetrically mounted on the output shaft 25 of the fertilizer conveying bin 2 and is connected to the first pulley by the first belt 61 at the same horizontal plane.

[0066] The third pulley 71 is fixedly installed on the output shaft 45 of the seed conveying chamber 4;

[0067] The fourth pulley 62 is fixedly installed on the output shaft 25 of the fertilizer conveying bin 2 and is connected to the third pulley 71 by the second belt 7 at the same horizontal plane.

[0068] Working principle:

[0069] The operator uses ropes to connect the trailer 13 to the rear suspension of the tractor and drives the tractor so that the front wheels 11 drive the overall support frame 1 forward to start the operation.

[0070] As the front wheel 11 rotates forward, the rotating shaft of the front wheel 11 drives the first pulleys on both sides to rotate. The first belt 61 on the first pulley begins to slide and is transmitted to the second pulley 60 at the other end through the first belt 61. The second pulley 60 can then drive the output shaft 25 of the fertilizer conveying bin 2 to rotate, so as to complete the fertilizer conveying operation.

[0071] Similarly, when the output shaft 25 of the fertilizer conveying bin 2 rotates, the fourth pulley 62 installed on it rotates synchronously, and the second belt 7 on the fourth pulley 62 begins to slide. The second belt 7 transmits the power to the third pulley 71 at the other end, and the third pulley 71 can drive the output shaft 45 of the seed conveying bin 4 to rotate in order to complete the seed conveying operation.

[0072] The reason for choosing belt drive over chain drive is that belts are made of softer material, which makes the operation smoother, eliminates the need for adding lubricant and maintenance, reduces costs, and improves practicality.

[0073] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
