Description

Technical Field

[0001] The invention relates to the technical field of agricultural fertilization equipment, and in particular to a biological organic fertilizer fertilization equipment and method. Background Art

[0002] Crops are usually planted in ridges. During the growth process, bio-organic fertilizers need to be used to fertilize the crops to ensure their rapid growth. Mechanized fertilization devices are becoming more and more popular due to their high efficiency. The use of mechanical fertilization methods will bury bio-organic fertilizers in the soil, so that crop seeds have sufficient nutrients when they are grown.

[0003] According to the Chinese patent with the announcement number CN212086962U, a fertilizing device for biological organic fertilizer is disclosed. The device, through its structural design, utilizes the rotation of the moving wheel on the mounting frame, and the rotation of the moving wheel utilizes the transmission structure to drive the spiral feeding shaft to rotate, and then utilizes the spiral feeding shaft to send the fertilizer in the feed hopper from the guide pipe to the cutter head, and the cutter head moves forward under the drive of the mounting frame, and then the cutter head splits the soil, and then the fertilizer in the cutter head falls into the soil. At this time, the depth of the cutter head inserted into the soil is limited by the restriction of the sliding plate. When the fertilization depth needs to be adjusted, the position of the rectangular rod in the rectangular tube is adjusted, and then the height of the sliding plate is adjusted. After the adjustment, the fixing screw is screwed to fix the position of the rectangular rod. The device has a simple structure and solves the problems of deep fertilization and adjustment of fertilization depth.

[0040] An operating assembly 4 is provided on one side of the frame 1. The operating assembly 4 includes a handrail 405 installed on one side of the fertilizer box 2. An L-shaped rod 401 is provided on the handrail 405. A slide rail 403 is fixed on the inner side of the frame 1. The handrail 405 can be manually operated to push the frame 1 to stably walk in the furrow of the farmland; a gear column is fixed to the middle part of the driving shaft 501, and the outer sliding sleeve of the slide rail 403 is provided with a gear sleeve 402 meshing with the gear column, one end of the gear sleeve 402 is fixed to the lower end of the L-shaped rod 401, and a grip rod is fixed on the top of the L-shaped rod 401. The outer sleeve of the slide rail 403 is provided with a return spring 404 connected to the end of the gear sleeve 402;

[0041] Fixed frames 3 are welded on both sides of the frame 1, and a fertilizing mechanism 5 and a feeding mechanism 6 are arranged below the fixed frames 3. The fertilizing mechanism 5 includes a driving shaft 501 arranged below the two fixed frames 3. A support foot is integrally formed at the bottom of the fixed frame 3. A limiting sleeve 502 is fixed below the fixed frame 3 through the support foot. Two mutually meshing direction adjustment gears 503 are vertically arranged on one side of the outer side of the limiting sleeve 502. One of the direction adjustment gears 503 is movably connected to the support foot at the bottom of the fixed frame 3 through the central axis. Next, the feeding mechanism 6 includes an adjusting pin 601 fixed to another direction-adjusting gear 503, a driving shaft 501 connected to the adjusting pin 601 is arranged between two adjacent fixing frames 3, a swing arm 504 is fixed to the side of the direction-adjusting gear 503, the swing arm 504 is staggered, a hollow plug plate 505 is installed at one end of the swing arm 504, a feed port docking with the hose 203 is arranged at the upper end of the hollow plug plate 505, and a baffle 506 is connected to the open side of the lower end of the hollow plug plate 505 through a torsion spring;

[0042] The inner sliding connection of the limit sleeve 502 is connected with the valve block 602, and the valve block 602 is composed of a valve body matching the inner wall of the limit sleeve 502 and a parallel push rod. A spiral hole is opened inside the valve body of the valve block 602, and a spiral strip docking with the spiral hole is provided on the circumferential side surface of one end of the adjusting pin 601. Exhaust ports 603 are provided on both sides of the limit sleeve 502 close to the adjustment gear 503, and the side of the limit sleeve 502 away from the adjustment gear 503 is movably connected with two air guide channels 604.

[0043] In specific implementation, before sowing the crop seeds, mechanical hole-punching equipment is generally used to punch holes at intervals on the soil piles on both sides of the ridge, so as to ensure the interval growth of crops during subsequent sowing. By pushing the frame 1 to move intermittently along the ridge of the farmland, the fertilization mechanisms 5 on both sides of the frame 1 are placed above the sowing holes. When the grip on the L-shaped rod 401 is pulled to drive the gear sleeve 402 to engage with the tooth column of the drive shaft 501, the drive shaft 501 can drive the adjustment pin 601 to rotate forward, so that the two direction-adjusting gears 503 on one side of the limit sleeve 502 produce meshing transmission, and then the two vertically distributed direction-adjusting gears 503 can drive the two hollow plug plates 505 to be inserted into the soil in an arc direction through the staggered swing arms 504. When the two hollow plug plates 505 are inserted into the soil, the bottom ends of the two hollow plug plates 505 do not contact each other and a staggered gap is retained, which is convenient for the two hollow plug plates 505 to loosen the soil at the fertilization position in layers.

[0044] See also Figure 1-Figure 10 The hollow plug plate 505 is a crescent-shaped structure, and the width of the upper side of the hollow plug plate 505 is greater than the width of the lower side of the hollow plug plate 505. The hollow plug plate 505 adopts a crescent-shaped structure, which makes it convenient for the lower side of the hollow plug plate 505 to be easily inserted into the soil for fertilization.

[0045] See also Figure 3-Figure 12 An auxiliary gear 605 is fixed to one end of the air guide channel 604 close to the limiting sleeve 502, and a push-pull plate 606 is slidably connected inside the air guide channel 604, and the push rod on one side of the valve block 602 is connected to the push-pull plate 606; an auxiliary gear 605 is fixed to one end of the two air guide channels 604 close to the limiting sleeve 502, and the mutual engagement of the two auxiliary gears 605 ensures that the two hollow plug plates 505 have stability when they are relatively flipped;

[0046] The end of the push-pull plate 606 away from the push rod is integrally provided with a circular ring sleeve, and the middle part of the circular ring sleeve is slidably connected with a sealing block 607 of a semi-cylindrical structure, the center of the sealing block 607 is provided with a rotating shaft that moves with the inner wall of the hollow plug plate 505, and an adjusting groove 608 is opened on the rotating shaft, and the inner wall of the circular ring sleeve of the sealing block 607 is provided with a protrusion that docks with the adjusting groove 608, and the adjusting groove 608 is composed of a spiral groove and a straight groove connected. When the protrusion on the inner wall of the circular ring sleeve enters the straight groove along the spiral groove of the adjusting groove 608, the sealing block 607 will limit the angle on the upper side of the hollow plug plate 505, and it can ensure that the arc surface of the sealing block 607 blocks the feed port on the upper side of the hollow plug plate 505;

[0047] An air pump 7 is installed on one side of the frame 1 close to the fertilizer box 2. The lower end of the air pump 7 is connected to an air pipe, and the air pipe is connected and docked with the air inlet at the top of the limiting sleeve 502. When the air pump 7 is running, it will supply compressed air into the limiting sleeves 502 on both sides of the frame 1 through the air pipe.

[0048] In a specific implementation, when the driving shaft 501 drives the adjusting pin 601 to rotate forward and drives the two hollow plug plates 505 to be inserted into the soil, the forward rotation of the adjusting pin 601 will be threadedly transmitted through the spiral strip at one end and the spiral hole in the valve block 602, so that the adjusting pin 601 pushes the valve block 602 to move forward in the limiting sleeve 502, so that the valve block 602 pulls the push-pull plate 606 to slide in the air guide channel 604 through the push rod parallel to the side, so that the push-pull plate 606 passes through the protrusion on the inner wall of the end ring sleeve and the adjusting groove 60 of the rotating shaft. 8 is squeezed, so that the protrusion moves along the spiral groove of the adjusting groove 608, which causes the sealing block 607 on the rotating shaft to flip, and the flipped sealing block 607 blocks the feed port with the arc surface side. In this process, the gas supplied by the air pump 7 enters the hollow plug plate 505 along the limiting sleeve 502 and the air guide channel 604, and finally the compressed air drives the biological organic fertilizer to push open the baffle 506, so that the two dislocated hollow plug plates 505 introduce the fertilizer into the soil in layers, which can prevent the fertilizer from being blown away by the wind during the fertilization process;

[0049] When the gripping rod at the top of the L-shaped rod 401 is released, the tooth sleeve 402 on the slide rail 403 is pushed and reset by the reset spring 404, so that the tooth sleeve 402 is reversely meshed with the tooth column of the drive shaft 501, so that the direction-adjusting gear 503 on one side of the limit sleeve 502 produces a reverse meshing transmission, ensuring that the swing arm 504 can drive the hollow plug plate 505 to flip upward and separate from the soil. When separating from the soil, the hollow plug plate 505 with a crescent-shaped structure will not dig out the soil of the sowing hole, and there is no need to use soil-digging equipment to backfill the soil. The compressed air supplied into the hollow plug plate 505 will continue to drive the fertilizer to be discharged along the opening on the lower side of the hollow plug plate 505, so that the biological organic fertilizer is spread in the soil along an arc trajectory and surrounds the sowing hole, ensuring that the amount of fertilization will not be too concentrated.

[0050] When the driving shaft 501 drives the hollow plug plate 505 to flip upward, the adjusting pin 601 and the spiral hole of the valve block 602 are reversely threaded, which will cause the adjusting pin 601 to push the valve block 602 to move in the opposite direction in the limit sleeve 502, so that the push rod on the side of the valve block 602 pushes the push-pull plate 606 to move, so that the push-pull plate 606 drives the sealing block 607 to reverse through the circular ring sleeve at the end. At this time, the sealing block 607 will open the feed port on the upper side of the hollow plug plate 505. In this process, the feed in the feeding bin 201 is fed through the auger 202. The biological organic fertilizer is introduced into the hollow plug plate 505 along the hose 203; when the push rod of the valve block 602 pushes the push-pull plate 606 to move, the valve body of the valve block 602 moves through the air inlet on the upper side of the limiting sleeve 502. At this time, the gas supplied by the air pump 7 is discharged outward along the exhaust port 603 on the limiting sleeve 502, and the exhausted air is sprayed toward the hollow plug plate 505 from both sides of the limiting sleeve 502. In this process, compressed air can be prevented from entering the hollow plug plate 505 to cause the waste of biological organic fertilizer.

[0051] See also Figure 1 and Figure 2 A polished rod 8 is fixed parallel to one side of the fertilizer box 2 close to the handrail 405, and a horizontal plate 9 is slidably connected to the polished rod 8. Sowing tubes 10 are arranged at both ends of the horizontal plate 9. A threaded rod 11 threadedly connected to the horizontal plate 9 is arranged between the two polished rods 8, and the threaded rod 11 is movably connected to the outer side surface of the fertilizer box 2 through a bearing.

[0052] During specific implementation, by rotating the threaded rod 11 and the cross plate 9 for threaded transmission, the cross plate 9 can be driven to move horizontally along the light rod 8, so as to facilitate the adjustment of the distance between the sowing tube 10 and the fertilizing mechanism 5. Because mechanical hole-punching equipment is generally used to punch holes at intervals on the soil piles on both sides of the ridge before sowing the crop seeds, when adjusting the distance between the sowing tube 10 and the fertilizing mechanism 5, it can ensure that when the fertilizing mechanism 5 on the front side of the frame 1 fertilizes the previous sowing hole, it is convenient for the sowing tube 10 on the rear side of the frame 1 to position and sow the next sowing hole. When the fertilizing equipment rolls over, the sowing tubes 10 on both sides of the frame 1 and the soil on both sides of the ridge are supported, so that the fertilizing equipment will only tilt sideways without tipping over.

[0053] A method for applying biological organic fertilizer comprises the following steps:

[0054] S1, introducing the biological organic fertilizer into the fertilizer box 2 for storage, and pushing the frame 1 to move intermittently in the furrows of the farmland;

[0055] S2, adjusting the position of the control valve block 602 inside the limiting sleeve 502 by the feeding mechanism 6, so that the feeding mechanism 6 controls the fertilizer and the compressed air to alternately enter the hollow plug plate 505;

[0056] S3. The hollow insert plate 505 is controlled to flip up and down by the operating component 4, so that the fertilizer can be applied in layers in the soil.
