Description

Technical Field

[0001] The present application relates to the technical field of crop fertilization, and in particular to a triangular fertilizer applicator for promoting deep rooting of perennial sugarcane. Background Art

[0002] In the production of sugar cane, perennial sugarcane cultivation is the most important management system. More than 70% of sugarcane in my country is perennial sugarcane, which plays an important role in ensuring the safety of sugar supply. In the production of perennial sugarcane, fertilization management is relatively extensive, and even fertilization without soiling and fertilizer application on top of the mulch film are prone to problems such as low fertilizer utilization rate of perennial sugarcane, uneven seedling emergence, and even more pond shortages and broken ridges, which seriously affect the yield and sugar formation of perennial sugarcane. One of the main reasons for these problems is the lack of attention to timely fertilization management of perennial sugarcane. The absorption of nutrients by perennial sugarcane seedlings mainly depends on the old root system of the previous crop of sugar cane, and its function has been greatly reduced. The main purpose of timely fertilization management is to guide and promote the growth of new roots.

[0003] Existing fertilization devices often use broad-spectrum broadcasting followed by soil covering or simple mechanical injection, resulting in uneven distribution of fertilizers in the soil. The fertilizers are too concentrated in a certain area or too dispersed, and cannot effectively reach the main growth area of ​​the new sugarcane roots. This uneven distribution not only reduces the utilization rate of fertilizers, but also causes local nutrient excess or deficiency in the soil, affecting the normal growth of the new roots of perennial sugarcane and the efficient absorption of nutrients, thereby affecting the growth and development of the aboveground part of the sugarcane.

[0004] A new fertilization device is needed to avoid fertilizer loss, meet the efficient nutrient absorption of the roots of the tillage layer, promote the growth of sugarcane roots, especially new roots, into deeper soil, and enhance the growth potential and lodging resistance of sugarcane.

The bottom of the screening net 111 is convex upward to form an arc-shaped blanking portion 115, and the two sides of the blanking portion 115 are concave to form two arc-shaped grooves. A guide plate 113 is installed obliquely downward at the bottom of the storage barrel 101 below the blanking portion 115, and the two guide plates 113 form a V-shaped structure. A plurality of discharge ports 114 are provided at the bottom of the storage barrel 101, which pass through the bottom of the guide plate 113. The discharge ports 114 are located between the two guide plates 113, and the discharge pipe 412 and the corrugated hose 301 of the conveying component 3 are respectively connected to a discharge port 114.

[0051] The fertilizer accumulates on the top of the screening net 111.

The dropping portion 115 is provided to facilitate the fertilizer in the storage barrel 101 to enter, pass through the screening net 111, and then enter the discharge port 114 through the guide plate 113.

[0052] The inner wall of the storage barrel 101 and the outer wall of the screening net 111 are fixedly connected with a plurality of inner gear rings 112, which are distributed along the arc-shaped protrusions and arc-shaped grooves. Two guide plates 113 are fixedly connected to the bottom of the screening net 111, and a plurality of discharge ports 114 are opened at the bottom of the outer wall of the storage barrel 101.

[0053] like Figure 1 , Figure 2 and Figure 6-Figure 9 As shown, a stirring assembly 2 is installed on the inner wall of the storage assembly 1, and the stirring assembly 2 is used to stir and crush the fertilizer.

The brush roller 207 and the crushing roller 218 can rotate circumferentially along the inner wall of the screening net 111 to crush and stir the fertilizer.

[0054] The driving mechanism includes a rotating shaft 110, a machine base 108, and a second motor 109. The rotating shaft 110 is rotatably installed inside the storage barrel 101 along the axial direction of the storage barrel 101.

The first spring 203 enables the driving mechanism to drive the brush roller 207 and the crushing roller 218 to rotate in the storage barrel 101, and the elastic force of the first spring 203 makes the second gear 220 always mesh with the inner gear ring 112, thereby ensuring the normal rotation of the stirring shaft 206 and the output shaft 217.

[0057] The rotating shaft 110 is driven to rotate by the second motor 109, and the connecting arm 201 is driven to rotate by the rotating shaft 110, and the brush roller 207 is driven to roll along the inner wall of the storage barrel 101 and the outer wall of the screening net 111 by the connecting arm 201.

When the driving mechanism drives the brush roller 207 and the crushing roller 218 to rotate in the storage barrel 101, the scraper 210 can be pressed against the inner wall of the screening net 111 by the elastic force of the second spring 215, so as to better scrape up the fertilizer attached to the screening net 111. At the same time, through the buffering effect of the second spring 215, when the scraper 210 scrapes the fertilizer attached to the screening net 111, a buffer space for the scraper 210 to be contracted by force is provided, thereby effectively preventing the fertilizer from getting stuck in the scraper mechanism and causing the stirring assembly to fail to operate normally.

The conveying assembly 3 includes a feed pipe 412 and a corrugated hose 301 respectively arranged corresponding to the main crushing part and the auxiliary crushing part. One end of the feed pipe 412 is connected to the storage barrel 101 and the other end is connected to the main crushing part. One end of the corrugated hose 301 is connected to the storage barrel 101 and the other end is connected to the auxiliary crushing part. The inclination angle of the corrugated hose 301 changes with the change in the spacing of the auxiliary crushing parts in the fertilization assembly 4, and the corrugated hose 301 maintains a straight line of material delivery during the change of the inclination angle.

[0067] The upper end of the feed pipe 412 of the conveying assembly 3 is fixedly connected to the storage barrel 101, and the feed pipe 412 is communicated with the feed port 114 located in the middle of the storage barrel 101, the lower end of the feed pipe 412 extends to the inside of the first conveying pipe 407, and a discharge hole 413 is opened on the side wall of the feed pipe 412 located inside the first conveying pipe 407.

[0068] The conveying assembly 3 also includes a first support plate 303 and a second support plate 304, the second support plate 304 is fixedly installed at the bottom of the storage barrel 101, and support rods 305 are fixedly installed on the first support plate 303 and the second support plate 304, and collars 306 are fixedly installed on the two support rods 305, and a storage sleeve 307 is fixedly installed on the collar 306 installed on the second support plate 304, and a telescopic rod 308 is fixedly installed on another collar 306 installed on the first support plate 303, and the telescopic rod 308 is slidably arranged in the storage sleeve 307, and a plurality of connecting strips 302 are fixedly connected to the corrugated hose 301, and the connecting strips 302 located at the upper and lower ends of the corrugated hose 301 are fixedly connected to the storage sleeve 307 and the telescopic rod 308 respectively; it can prevent the corrugated hose 301 from being compressed or stretched, and the pipeline always remains straight to avoid bending and causing poor discharge.

[0069] A pressure plate 309 is fixedly installed on the upper end of the telescopic rod 308, and the pressure plate 309 is slidably arranged in the storage sleeve 307. A third spring 310 is arranged in the storage sleeve 307, and one end of the third spring 310 is fixedly connected to the pressure plate 309, and the other end of the third spring 310 is fixedly connected to the inner wall of the upper end of the storage sleeve 307.

[0070] Working principle: The first bracket 102 and the second bracket 103 are welded to the agricultural machinery, and the fertilizer is put into the storage barrel 101. At this time, the fertilizer is accumulated on the top of the screening net 111. At this time, the fertilizer with smaller particles flows to the bottom of the screening net 111, and the fertilizer with larger particles is accumulated above the screening net 111. The protrusions and grooves facilitate the fertilizer in the storage barrel 101 to enter through the screening net 111 and then enter the discharge port 114 through the guide plate 113.

[0071] The second motor 109 drives the rotating shaft 110 to rotate, the rotating shaft 110 drives the connecting arm 201 to rotate, and the connecting arm 201 drives the brush roller 207 to roll along the inner wall of the storage barrel 101 and the screening net 111. At this time, the second gear 220 is meshed with the inner gear ring 112 on the storage barrel 101 and the screening net 111, so that the brush roller 207 rotates around the rotating shaft 110 while maintaining self-rotation. The second gear 220 is meshed with the inner gear ring 112, so the first gear 219 and the second gear 220 can be meshed, driving the brush roller 207 and the crushing roller 218 to rotate in opposite directions at the same time, so that the brush roller 207 and the crushing roller 218 cooperate to crush the fertilizer during the process of rotating along the inner wall of the storage barrel 101.

[0072] When the brush roller 207 rolls along the screening net 111, the lifting arm 205 drives the slider 204 to slide along the outer wall of the slide rod 202, and the slider 204 squeezes the first spring 203, so that the brush roller 207 can adapt to the shape of the screening net 111 and expand and contract;

[0073] When the connecting arm 201 rotates, the scraper 210 is driven to slide along the inner wall of the storage barrel 101 and the inner wall of the screening net 111. Under the elastic force of the first spring 203, the scraper 210 can always contact the inner wall of the storage barrel 101 and the outer wall of the screening net 111, so that the fertilizer compacted on the screening net 111 and the inner wall of the storage barrel 101 can be scraped off. At this time, the compacted fertilizer will accumulate in the inclined plate 208, the rubber arc plate 209 and the scraper 210. When the gear 209 and the scraper 210 rotate upward, the compacted fertilizer slides along the inclined plate 208 to between the two baffles 216. When the second gear 220 rotates, it drives the first gear 219 to rotate, and the output shaft 217 is driven to rotate by the first gear 219, and the crushing roller 218 is driven to rotate by the output shaft 217. The crushing roller 218 cooperates with the brush roller 207 to squeeze the compacted fertilizer, so that the fertilizer can be dispersed into uniform particles, which is convenient for transporting the fertilizer to the designated fertilization position;

[0074] The fertilizer is gathered at the discharge port 114 through the guide plate 113, and the fertilizer can enter the corrugated hose 301 and the discharge pipe 412;

[0075] The third motor 404 drives the two first bevel gears 403 to rotate through the second bevel gear 405, and drives the second screw 402 to rotate through the two first bevel gears 403, so that the two slides 406 drive the second conveying pipe 408 to move, and drive the first crushing knife 409 and the first slide 410 to move through the second conveying pipe 408, so that they can be adjusted according to the spacing between the ridges;

[0076] When the second conveying pipe 408 moves, it can drive the first support plate 303 to move. The first support plate 303 drives the telescopic rod 308 to move through the support rod 305 and the collar 306. At this time, the storage sleeve 307 rotates around the support rod 305 on the second support plate 304. When the telescopic rod 308 moves, it pushes the pressure plate 309 to slide along the inner wall of the storage sleeve 307 and squeezes the third spring 310, so that the corrugated hose 301 is compressed, so as to adapt to the adjustment of the distance between the two second conveying pipes 408. At the same time, it can prevent the corrugated hose 301 from being compressed or stretched. The pipeline always remains straight to avoid bending and causing poor discharge.

[0077] The first motor 105 drives the first screw 106 to rotate, so that the lifting plate 107 drives the first conveying pipe 407 to move, and the first conveying pipe 407 drives the first crushing knife 409 and the first slide 410 in the middle to move, so that the height of the first crushing knife 409 in the middle can be adjusted to adapt to the depth of the furrows between the ridges;

[0078] The agricultural machinery drives multiple first crushing knives 409 to move, and a triangular position is formed between the multiple first crushing knives 409, which can crush the soil on the sides of the gully and the ridges on both sides of the gully at the same time. The fertilizer is transported to the space between the first crushing knife 409 and the first slide 410 through the second conveying pipe 408 and the first conveying pipe 407, and is applied to the soil through the first discharge trough 411. After the soil is crushed by the first crushing knife 409, the crushed soil will cover the fertilizer along the inclined surfaces on both sides of the first crushing knife 409, thereby avoiding the loss of fertilizer.
