Description

Technical Field

[0001] This application relates to the technical field of crop fertilization, and particularly relates to a triangular fertilizer applicator for promoting the deep rooting of ratoon sugarcane roots. Background Art

[0002] In the production of sugarcane, ratoon sugarcane cultivation is the most important management system. More than 70% of the sugarcane in China is ratoon sugarcane, which plays an important role in ensuring the safety of sugar supply. In ratoon sugarcane production, fertilization management is relatively extensive. Even when fertilizing, soil covering is not carried out, and fertilizers are applied above the plastic film. This easily leads to problems such as low fertilizer utilization rate of ratoon sugarcane, uneven emergence, and even many gaps and ridges being broken, seriously affecting the yield and sugar formation of ratoon sugarcane. One of the main reasons for these problems is the lack of attention to the timely fertilization management of ratoon sugarcane. The absorption of nutrients by ratoon sugarcane seedlings mainly depends on the old roots of the previous crop of sugarcane, whose functions have 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 adopt the methods of broad-spectrum spreading followed by soil covering or simple mechanical injection, resulting in uneven distribution of fertilizers in the soil. The fertilizers are either too concentrated in a certain area or too scattered, and cannot effectively reach the main growth area of the new roots of sugarcane. This uneven distribution not only reduces the utilization rate of fertilizers, but also causes local nutrient surplus or deficiency in the soil, affecting the normal growth of the new roots of ratoon sugarcane and the efficient absorption of nutrients, thus affecting the growth and development of the above-ground part of sugarcane.

[0004] There is a need for a new fertilization device to avoid fertilizer loss, meet the efficient absorption of nutrients by the roots in the tillage layer, promote the growth of the roots of sugarcane, especially new roots, into deeper soil, and enhance the growth potential and lodging resistance of sugarcane.

[0048] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0049] As Figures 1-5 shown, the storage component 1 is used for storing fertilizers. The storage component 1 includes a first bracket 102, a second bracket 103, a storage cylinder 101, and a screening net 111. The storage cylinder 101 is fixedly installed at the upper ends of the first bracket 102 and the second bracket 103. The screening net 111 is fixedly installed inside the storage cylinder 101, and a sealing cover is installed at the feed inlet of the outer wall of the storage cylinder 101.

[0050] The screening net 111 is fixedly installed on the inner wall of the storage cylinder 101. The bottom of the screening net 111 bulges upward to form an arc-shaped material dropping part 115, and both sides of the material dropping part 115 are concave to form two arc-shaped grooves. A guide plate 113 is installed obliquely downward at the position below the material dropping part 115 at the bottom of the storage cylinder 101, and the two guide plates 113 form a V-shaped structure. A plurality of blanking ports 114 penetrating the bottom of the guide plate 113 are opened at the bottom of the storage cylinder 101. The blanking ports 114 are located between the two guide plates 113, and the blanking pipe 412 and the corrugated hose 301 of the conveying component 3 are respectively communicated with one blanking port 114.

[0051] The fertilizers are piled up on the top of the screening net 111. At this time, the fertilizers with smaller particles flow to the lower part of the screening net 111, and the fertilizers with larger particles are piled up above the screening net 111. By setting the material dropping part 115, it is convenient for the fertilizers in the storage cylinder 101 to enter through the screening net 111 and then enter the blanking port 114 through the guide plate 113.

[0052] A plurality of internal gear rings 112 are fixedly connected to the inner wall of the storage cylinder 101 and the outer wall of the screening mesh 111. The internal gear rings 112 are distributed along the arc-shaped protrusions and arc-shaped grooves. Two guide plates 113 are fixedly connected to the bottom of the screening mesh 111. A plurality of discharge openings 114 are provided at the bottom of the outer wall of the storage cylinder 101.

[0053] As Figure 1 、 Figure 2 and Figures 6-9 shown, a stirring assembly 2 is installed on the inner wall of the storage assembly 1. The stirring assembly 2 is used for stirring and pulverizing the fertilizer. The stirring assembly 2 includes a driving mechanism, a connecting mechanism, a brush roller 207, and a crushing roller 218. The driving mechanism is installed on the storage cylinder 101. The connecting mechanism is fixedly installed on the driving mechanism. The brush roller 207 and the crushing roller 218 are rotatably installed on the connecting mechanism through a stirring shaft 206 and an output shaft 217 respectively. The brush roller 207 and the crushing roller 218 can rotate circumferentially along the inner wall of the screening mesh 111 for pulverizing and stirring 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 cylinder 101 along the axial direction of the storage cylinder 101. The machine base 108 is fixedly installed at the end of the storage cylinder 101. The second motor 109 is fixedly installed on the machine base 108. The output end of the second motor 109 is drivingly connected to the rotating shaft 110. The connecting mechanism is fixedly installed at both ends of the rotating shaft 110 located inside the storage cylinder 101.

[0055] The connecting mechanism includes two connecting arms 201 respectively fixedly installed at both ends of the rotating shaft 110. A first sliding groove 221 is formed on the two connecting arms 201 along the radial direction of the rotating shaft 110. A sliding rod 202 is fixedly installed in the first sliding groove 221. A slider 204 is slidably penetrated through the two sliding rods 202. A lifting arm 205 is fixedly connected to the slider 204. The stirring shaft 206 and the output shaft 217 are rotatably installed between the two lifting arms 205. Second gears 220 are installed at both ends of the stirring shaft 206. First gears 219 are installed at both ends of the output shaft 217. The first gears 219 are meshed with the second gears 220. The second gears 220 are also meshed with the internal gear rings 112. The internal gear rings 112 are arranged on the circumferences of the inner side walls at both ends of the screening mesh 111. The shape of the internal gear rings 112 matches the shape of the material falling part 115.

[0056] A first spring 203 is sleeved on the sliding rod 202. One end of the first spring 203 is fixedly connected to the connecting arm 201, and the other end of the first spring 203 is fixedly connected to the inner side wall of the top of the first sliding groove 221. During the process of the driving mechanism driving the brush roller 207 and the crushing roller 218 to rotate in the storage cylinder 101, the elastic force of the first spring 203 makes the second gear 220 always meshed with the internal gear ring 112, so as to ensure the normal rotation of the stirring shaft 206 and the output shaft 217.

[0057] The second motor 109 drives the rotation of the rotating shaft 110. The rotating shaft 110 drives the rotation of the connecting arm 201. The connecting arm 201 drives the brush roller 207 to roll along the inner wall of the storage cylinder 101 and the outer wall of the screening mesh 111. At this time, the second gear 220 meshes with the internal gear ring 112 on the storage cylinder 101 and the screening mesh 111, so that the brush roller 207 rotates around the rotating shaft 110 and maintains its own rotation. Since the second gear 220 meshes with the internal gear ring 112, the first gear 219 can mesh with the second gear 220 to drive the brush roller 207 and the crushing roller 218 to rotate in opposite directions at the same time. Thus, the brush roller 207 and the crushing roller 218 cooperate to crush the fertilizer during the rotation along the inner wall of the storage cylinder 101. The brush roller 207 and the crushing roller 218 can rotate circumferentially along the inner wall of the screening mesh 111 to crush and stir the fertilizer, and clean the fertilizer blocked in the screening mesh 111 and the fertilizer attached to the inner wall of the storage cylinder 101, thereby preventing the screening mesh 111 from being blocked.

[0058] The stirring assembly 2 further includes a scraping mechanism. The scraping mechanism includes two baffles 216, an inclined plate 208, a rubber arc plate 209, and a scraper 210. The two baffles 216 are respectively fixedly installed on the front and rear side walls of the lifting arm 205. The inclined plate 208 is inclinedly installed on the rear side wall of the lifting arm 205 and is connected to the lower end of the baffle 216 on the same side. The lower end of the inclined plate 208 is fixedly connected to the rubber arc plate 209. The lower end of the rubber arc plate 209 is fixedly connected to the scraper 210. During the process that the driving mechanism drives the brush roller 207 and the crushing roller 218 to rotate in the storage cylinder 101, the scraper 210 can scrape up the fertilizer attached to the screening mesh 111, and under the guiding action of the inclined plate 208 and the rubber arc plate 209, it is crushed by the rotating brush roller 207 and crushing roller 218.

[0059] The left and right ends of the scraper 210 are fixedly installed with first connection blocks 211. A sliding arm 212 is installed on the two first connection blocks 211. A second chute 222 is formed along the length direction of the sliding arm 212 on the sliding arm 212. A connecting rod 213 is fixedly installed in the second chute 222. A second connection block 214 is slidably penetrated through the connecting rod 213. The second connection block 214 is fixedly connected to the inclined plate 208.

[0060] A second spring 215 is sleeved on the connecting rod 213. One end of the second spring 215 is fixedly connected to the second connecting block 214, and the other end of the second spring 215 is fixedly connected to the inner side wall of the bottom of the second chute 222. During the process that the driving mechanism drives the brush roller 207 and the crushing roller 218 to rotate in the storage cylinder 101, the elastic force of the second spring 215 can make the scraper 210 abut against the inner wall of the screening mesh 111, so as to better scrape up the fertilizer adhering to the screening mesh 111. At the same time, through the buffering effect of the second spring 215, when the scraper 210 scrapes the caked fertilizer adhering to the screening mesh 111, a buffering space for the scraper 210 to contract under force is provided, thereby effectively preventing the caked fertilizer from jamming the scraping mechanism and causing the stirring assembly to fail to operate normally.

The fertilizing assembly 4 is connected to the conveying assembly 3, and the fertilizing assembly 4 is used for crushing the soil. The fertilizing assembly 4 includes a sliding frame 401.

[0066] As Figure 1 、 Figure 2 、 Figure 10 and Figure 11 As shown in

[0067] Two conveying assemblies 3 are installed on the outer wall of the storage assembly 1. The conveying assemblies 3 are used for conveying fertilizers. The conveying assemblies 3 include a blanking pipe 412 and a corrugated hose 301 respectively arranged corresponding to the main crushing member and the secondary crushing members. One end of the blanking pipe 412 is communicated with the storage cylinder 101 and the other end is communicated with the main crushing member. One end of the corrugated hose 301 is communicated with the storage cylinder 101 and the other end is communicated with the secondary crushing member. The inclination angle of the corrugated hose 301 changes following the change of the distance between the secondary crushing members in the fertilizing assembly 4, and the corrugated hose 301 maintains straight material conveying during the change of the inclination angle.

[0068] The conveying assembly 3 further 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 cylinder 101. A support rod 305 is fixedly installed on the first support plate 303 and the second support plate 304. Collars 306 are fixedly installed on both support rods 305. A receiving sleeve 307 is fixedly installed on the collar 306 installed on the second support plate 304. A telescopic rod 308 is fixedly installed on the other collar 306 installed on the first support plate 303. The telescopic rod 308 is slidably arranged in the receiving sleeve 307. 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 respectively fixedly connected to the receiving sleeve 307 and the telescopic rod 308; it can prevent the corrugated hose 301 from bending during compression or stretching, ensuring that the pipeline remains straight and avoiding poor discharge due to bending.

[0069] A pressure plate 309 is fixedly installed at the upper end of the telescopic rod 308. The pressure plate 309 is slidably arranged in the receiving sleeve 307. A third spring 310 is arranged in the receiving sleeve 307. 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 receiving sleeve 307.

[0070] Working principle: Weld the first bracket 102 and the second bracket 103 on the agricultural machine, and put the fertilizer into the storage cylinder 101. At this time, the fertilizer accumulates on the top of the screening net 111. At this time, the fertilizer with smaller particles flows to the lower part of the screening net 111, and the fertilizer with larger particles accumulates above the screening net 111. The protrusions and grooves facilitate the fertilizer in the storage cylinder 101 to enter and pass through the screening net 111 and then enter the feeding port 114 through the guiding plate 113.

[0071] Drive the rotating shaft 110 to rotate through the second motor 109, drive the connecting arm 201 to rotate through the rotating shaft 110, and drive the brush roller 207 to roll along the inner walls of the storage cylinder 101 and the screening net 111 through the connecting arm 201. At this time, the second gear 220 meshes with the internal gear ring 112 on the storage cylinder 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 meshes with the internal gear ring 112, so the first gear 219 can mesh with the second gear 220 to drive 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 rotation along the inner wall of the storage cylinder 101.

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

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

[0074] The fertilizer is gathered at the feeding port 114 through the guiding plate 113. At this time, the fertilizer can enter the inside of the corrugated hose 301 and the feeding pipe 412;

[0075] The third motor 404 drives two first bevel gears 403 to rotate through the second bevel gear 405. Through the two first bevel gears 403, the second screw rods 402 are respectively driven to rotate, so that the two sliding seats 406 drive the second conveying pipe 408 to move. Through the second conveying pipe 408, the first crushing knife 409 and the first sliding piece 410 are driven to move, so as to be adjusted according to the distance 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 receiving sleeve 307 rotates around the support rod 305 on the second support plate 304. When the telescopic rod 308 moves, it pushes the pressing disc 309 to slide along the inner wall of the receiving 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 avoid the pipeline from always being straight during the compression or stretching process of the corrugated hose 301, and avoid bending, resulting in poor discharge;

[0077] The first motor 105 drives the first screw rod 106 to rotate, so that the lifting plate 107 drives the first conveying pipe 407 to move. Through the first conveying pipe 407, the first crushing knife 409 and the first sliding piece 410 in the middle are driven to move, so as to adjust the height of the first crushing knife 409 in the middle to adapt to the depth of the gully between the ridges;

[0078] Driven by agricultural machinery, multiple first crushing knives 409 move, and a triangular position is formed among the multiple first crushing knives 409, enabling the simultaneous crushing of the soil on the side of the gully and the ridges on both sides of the gully. Fertilizer is transported to the space between the first crushing knife 409 and the first sliding plate 410 through the second conveying pipe 408 and the first conveying pipe 407, and is applied into the soil through the first discharge chute 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, thus avoiding the loss of fertilizer.
