Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery and equipment, and in particular to a fertilizer mixing and fertilizing device for agricultural planting. Background Art

[0002] When fertilizing young fruit trees, hole-fertilization is usually adopted, that is, after drilling several fertilizer holes evenly around the young trees, the fertilizer particles and the excavated soil are poured into the fertilizer holes, and then the soil and fertilizer in the fertilizer holes are evenly mixed with tools such as shovels to achieve concentrated supply of fertilizer to the root system of the fruit trees and improve fertilizer utilization rate. However, the operation process is relatively cumbersome. When manually using a shovel to mix the soil and fertilizer, when the amount of soil and fertilizer is relatively large, it takes a long time to mix the fertilizer and soil evenly, resulting in low efficiency. In addition, during the drilling process, since the fertilizer holes are close to the fruit trees, if there are thicker roots at the fertilizer holes, the drill bit is likely to pull the roots of the fruit trees, causing the fruit trees to be pulled as a whole, causing damage to the fruit trees. Summary of the invention

[0006] Furthermore, a shielding cover is fixedly connected to the outer side of the inner tube via a connecting block.

[0007] Furthermore, guide plates are fixedly connected to the inner side of the third discharge port near the upper side of the inner tube, each guide plate is tilted downward toward one side of the third discharge port, and the tilt angle of the guide plate increases from top to bottom; the bottom of the inner side of the inner tube is in a truncated cone shape.

[0020] A shielding cover 9003 is fixedly connected to the outer side of the inner tube 9 via a connecting block, and a strip-shaped through groove is provided on the connecting tube 4 for the shielding cover 9003 to slide up and down.

[0021] A guide plate 9004 is fixedly connected to the inner side of each of the two third discharge ports 9002 close to the upper side of the inner tube 9. Each guide plate 9004 is tilted downward toward one side of the third discharge port 9002, and the tilt angle of the guide plate 9004 increases from top to bottom. The falling fertilizer is intercepted and guided by the guide plate 9004 to ensure that the fertilizer can flow through all the third discharge ports 9002.

[0022] It also includes a third driving member 301, a baffle 302 and a material dial 303; four second discharge ports 8001 are opened on the lower side of the storage tube 8; each second discharge port 8001 is slidably connected to a baffle 302, and the second discharge port 8001 is blocked by the baffle 302; each second discharge port 8001 is fixedly connected to a third driving member 301, and the third driving member 301 is an electric push rod; all baffles 302 are commonly fixedly connected to the material dial 303.

[0023] It also includes a positioning ruler 2; two positioning rulers 2 are fixedly connected to the front side of the frame 1, and scales are set on the positioning rulers 2.

[0024] It also includes a material-moving rod 201 ; two material-moving rods 201 are fixedly connected to the upper side of the storage cylinder 8 .

[0025] The lower side of the inner tube 9 is configured to be in a pointed cone shape so as to facilitate the insertion of the inner tube 9 into the soil.

[0026] The partition 7001 is arranged to be inclined toward the lower middle side to promote the fertilizer to flow toward the middle.

[0027] The following description is based on Figure 1 is a viewing angle reference, where the side where the roller 1002 is located is the front side and the rear side; During operation, firstly, a proper amount of fertilizer is added into the storage barrel 7 through the opening on the upper side of the storage barrel 7, so that the fertilizer is located on the upper side of the partition 7001, and the opening is blocked, and then the frame 1 is pushed forward by manually holding the handle 1001, and the roller 1002 is used as a support and rolls. When the cutting barrel 104 moves to the position to be fertilized next to the fruit tree, the button on the handle 1001 is pressed manually to start the motor 5 to drive the connecting pipe 4 to rotate, and then the scraper plate 101 and the spiral auger 6 are driven to rotate through the connecting pipe 4, so that the soil is loosened by the scraper plate 101, and the soil is stirred by the scraper plate 101. The soil is transported upwards through the spiral auger 6, and the handle 1001 is pressed downwards manually, so that the frame 1 rotates downwards around the roller 1002, thereby driving the fixed plate 3, the connecting pipe 4, the scraper plate 101 and the spiral auger 6 to move downwards through the frame 1, so as to gradually drill a fertilizer hole in the soil. The fixed plate 3 is rotatably connected to the frame 1, so that the scraper plate 101 and the spiral auger 6 move downwards in a vertical state, and at this time, the storage barrel 7 slides upwards relative to the guide rail 3001, and the elastic member 3002 is compressed. At this time, the storage barrel 7 and the cutting barrel 104 cooperate to The soil transported upward by the spiral auger 6 is stored. In order to prevent the scraper 101 and the spiral auger 6 from pulling the root system of the fruit tree when drilling, because the fertilizer hole is close to the fruit tree, if there is a thick root system at the fertilizer hole, resulting in the fruit tree being pulled as a whole and causing damage to the fruit tree, while the connecting pipe 4 drives the scraper 101 to rotate, the cutting ring 102 is driven to rotate through the scraper 101, and because the saw teeth 10201 are lower than the lower side of the spiral auger 6, the saw teeth 10201 are in contact with the soil first, so as to achieve First, cut off the roots at the edge of the fertilization hole, and then perform drilling operations through the spiral auger 6 to prevent the spiral auger 6 from pulling the roots of the fruit trees. It should be noted that when the cutting ring 102 rotates, the cutting effect on the root system is guaranteed by the sharp side of the saw tooth 10201. When there is a stone under the cutting ring 102, the flat bottom of the saw tooth 10201 contacts the stone first, and then the stone can be pushed away in time by the continuously rotating scraper 101 to avoid direct contact between the stone and the sharp side of the saw tooth 10201, so as to reduce the wear on the sharp side of the saw tooth 10201.

[0028] When the connecting tube 4 moves downward, the storage cylinder 8 is driven downward by the connecting tube 4. During this process, the fertilizer in the storage cylinder 7 flows into the storage cylinder 8 from the opening on the upper side of the storage cylinder 8 until the storage cylinder 8 is full of fertilizer. When the spiral auger 6 is completely drilled into the soil, the handle 1001 is pushed upward manually, so that the frame 1 rotates upward around the roller 1002 to reset, and the connecting tube 4 and the parts connected thereto are driven upward to reset through the frame 1, and the motor 5 is controlled to drive the connecting tube 4 and the spiral auger 6 to reverse, and the storage in the storage cylinder 7 and the cutting cylinder 104 is released through the spiral auger 6. The soil is transported downward to the fertilization hole. At the same time, the first driving member 10 is controlled to push the inner tube 9 downward until the second feed port 9001 is aligned with the first feed port 4001, and the third discharge port 9002 is aligned with the first discharge port 4002, so that the fertilizer in the storage cylinder 8 can enter the inner tube 9 from the first feed port 4001 and the second feed port 9001, and then flow outward from the third discharge port 9002 and the first discharge port 4002 to the inside of the soil pile, so that under the stirring of the spiral auger 6, the fertilizer and soil are pushed into the fertilization hole, and at the same time, the fertilizer and soil are ensured to be evenly mixed.

[0029] It should be noted that when the fertilizer enters the inner tube 9 from the second feed port 9001 and flows downward, the fertilizer is intercepted and guided by the inclined guide plate 9004, so that when the fertilizer moves downward, part of the fertilizer on the inner side of each third discharge port 9002 is intercepted by the guide plate 9004, and the guide plate 9004 is inclined at an increasingly larger angle from top to bottom to ensure that after part of the fertilizer is intercepted by the guide plate 9004, there is still sufficient fertilizer to continue to move downward, ensuring that the fertilizer can flow through all the third discharge ports 9002, and the fertilizer falling to the bottom of the inner tube 9 is guided by the truncated inner bottom of the inner tube 9, and the fertilizer is guided to the third discharge port 9002 at the bottom, thereby avoiding the fertilizer from accumulating in the inner tube 9.

[0030] When the inner tube 9 moves downward, the shielding cover 9003 is driven downward by the inner tube 9 to block the upper opening of the storage cylinder 8 through the shielding cover 9003 to prevent the fertilizer in the storage cylinder 7 from entering the storage cylinder 8 again, thereby achieving a fixed amount of fertilizer applied each time and effectively ensuring the fertilization effect.

[0031] After all the soil and fertilizer are pushed into the fertilization hole by the spiral auger 6, the second driving member 103 is controlled to push the cutting cylinder 104 downward, and the edge of the fertilization hole is cut by the sharp edge on the lower side of the cutting cylinder 104 to further cut the root system at the edge of the fertilization hole, thereby ensuring the flatness of the root system section, which is conducive to the healing and regeneration of the root system.

[0032] In order to further ensure that the fertilizer and soil are mixed evenly, after the spiral auger 6 moves upward to leave the fertilization hole, the frame 1 can be pressed down again, and the spiral auger 6 can be controlled to rotate to stir and mix the soil and fertilizer. At the same time, the third driving member 301 can be controlled to push the baffle 302 and the dial plate 303 downward, so that the baffle 302 releases the blockage of the second discharge port 8001, so that part of the fertilizer in the storage tube 8 flows out from the second discharge port 8001, and the dial plate 303 is driven to rotate through the storage tube 8, so that this part of the fertilizer is dialed through the dial plate 303, so that it is evenly dispersed on the outside of the soil pile, and by cooperating with the fertilizer flowing outward from the third discharge port 9002 to the inside of the soil pile, the fertilizer can be evenly mixed with the soil, so as to further ensure the mixing effect of the fertilizer and the soil.

[0033] Since the distance between the fertilizer hole and the trunk of the fruit tree is different for fruit trees of different sizes, the frame 1 can be pushed forward to move the trunk of the fruit tree between the two positioning rulers 2 each time fertilizing, and the fertilization position can be located and determined by the scales on the positioning rulers 2.

[0034] It should be noted that when the connecting tube 4 drives the storage cylinder 8 to rotate, the storage cylinder 8 drives the material moving rod 201 to rotate, so that the fertilizer is moved by the material moving rod 201, which effectively avoids the fertilizer from agglomerating.

[0035] Example 2 On the basis of Example 1, Figure 2-Figure 7 As shown, a filter screen 9005 is also included; a filter screen 9005 is fixedly connected to each second feed port 9001.

[0036] When it is necessary to apply water and fertilizer to the fruit trees, the liquid containing the fertilizer can be added into the storage barrel 7. When the soil is hard, the frame 1 and the spiral auger 6 and the parts connected thereto can be pushed downward manually. At this time, the liquid in the storage barrel 7 flows into the storage barrel 8 from the upper opening of the storage barrel 8, and the motor 5 is controlled to drive the spiral auger 6 to rotate. After the soil is loosened by the spiral auger 6, the spiral auger 6 and the parts connected thereto are manually driven to reset upward, and then the first driving member 10 is controlled to push the inner tube 9 downward so that the inner tube 9 is inserted downward into the soil, so that the second feed inlet 9001 is aligned with the first feed inlet 9001. The feed ports 4001 are aligned, and then the liquid in the storage tube 8 flows into the inner tube 9 from the first feed port 4001 and the second feed port 9001. Then, when the inner tube 9 moves down to the third discharge port 9002 and separates from the connecting tube 4, the liquid can flow out from the third discharge port 9002 and mix into the soil. At the same time, the inner tube 9 drives the shielding cover 9003 to move downward, so that the liquid in the storage tube 8 can be squeezed through the shielding cover 9003, so that the liquid flowing out of the third discharge port 9002 has a certain pressure, so as to promote the rapid dispersion of the liquid in the soil, thereby ensuring the fertilization efficiency.

[0037] When the liquid flows into the inner tube 9 from the first feed port 4001 and the second feed port 9001, the incompletely dissolved fertilizer particles can be intercepted by the filter screen 9005 to prevent these large-volume fertilizer particles from flowing directly into the soil, causing more fertilizer particles to accumulate there and making the fertilizer distribution uneven.

[0038] It should be noted that when the inner tube 9 drives the shielding cover 9003 to reset upward, the third driving member 301 can be controlled to push the baffle 302 downward so that the baffle 302 releases the blockage of the second discharge port 8001 to balance the internal and external air pressures of the storage cylinder 8 through the second discharge port 8001.

[0039] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
