Description

Technical Field

[0001] The invention relates to the technical field of agricultural fertilization, and in particular to an agricultural fertilization device for automatic and uniform fertilization. Background Art

[0002] Agricultural fertilization equipment is an indispensable and important tool in modern agriculture. They can complete fertilization operations efficiently and accurately, and improve the yield and quality of crops. Fertilizer spreaders can greatly improve the efficiency of fertilization operations and save a lot of labor costs and time costs. Precision fertilization can not only reduce the use of fertilizers, but also reduce pollution to the environment, help protect soil and water resources, and fertilizer spreaders have a high degree of automation, which reduces the labor intensity of manual fertilization.

[0003] After searching, the Chinese patent with publication number CN114793579B discloses an agricultural fertilizer spreader that can automatically and evenly spread fertilizers, including an outer box, a fertilizer box is arranged on the upper part of the inner part of the outer box, and the inner bottom end of the fertilizer box is penetrated and slidably connected with two guide rods, and the top ends of the two guide rods are fixedly connected with support blocks, and the double-rod cylinder is started, and the double-rod cylinder drives the push blocks on the left and right sides to move to both sides at the same time, so that the fertilizer inside the top material troughs on both sides is pushed into the inclined tube through the guide pipe, and the fertilizer is discharged through the discharge pipe after entering the inclined tube. When the top material trough is retracted to the bottom end of the fertilizer box, new fertilizer is received again, so that the fertilizer can be pushed out through the pusher block after it is lifted up again, thereby achieving the purpose of automatic fertilization, solving the problems that the general fertilization machinery has a low degree of automation, cannot automatically and evenly fertilize, is inconvenient to adjust the fertilizer amount and fertilization nodes, has limitations in use, and is not practical. However, when this scheme is actually used, it still has the following shortcomings:

[0004] The fertilization method of the fertilization device is limited to simply adding fertilizer to the surface of the ground. Once there is abundant rain or heavy rainfall, the fertilizer on the surface is easily washed away and redistributed by rain due to lack of sufficient soil cover and fixation, and even forms accumulation in some low-lying areas or where water flows converge. This phenomenon not only leads to uneven distribution of fertilizers, but also may cause excess nutrients in some areas of the soil, while other areas are malnourished due to lack of fertilizers, thus seriously affecting the overall fertilization effect of the fertilizer.

[0005] Therefore, the present application provides an agricultural fertilization device that automatically and evenly applies fertilizers to meet the requirements of preventing fertilizers from being washed away by rainwater and applying fertilizers efficiently. Summary of the invention

[0073] like Figures 1 to 8 As shown, an agricultural fertilizer application equipment for automatic and uniform fertilizer application comprises a base 1 and two driving shafts 2, the two driving shafts 2 are symmetrically rotatably mounted on the bottom surface of the base 1, and both ends of the two driving shafts 2 are fixedly mounted with wheels 3, and also comprises: a fertilizer frame 4, fixedly mounted on the top surface of the base 1; a fertilizer storage box 5, fixedly mounted on the top surface of the fertilizer frame 4; a piercing assembly, arranged at the forward end of the base 1; two sealing seats 7, symmetrically fixedly mounted on the inner wall of the discharge end of the fertilizer storage box 5; a fertilizer adding assembly, arranged on the inner side of the fertilizer storage box 5 and located between the two sealing seats 7; a fertilizer discharging assembly, arranged on the inner side of the fertilizer frame 4; an opening 10, opened on the top surface of the base 1 and located at a position relative to the discharge end of the fertilizer storage box 5; a leak-proof assembly, arranged on the inner side of the opening 10; a traction frame 12, fixedly mounted on the forward end of the base 1;

[0074] When in use, the entire device can be moved to the use position, and the base 1 can be connected to the traction device through the traction frame 12, and then the fertilizer to be used can be added to the fertilizer storage box 5. In the process of the traction device driving the base 1 to move, the rotating wheel 3 rotates on the ground to drive the driving shaft 2 to rotate. When the driving shaft 2 rotates, the piercing component can be driven, so that holes are pierced on the ground on the forward path of the base 1, so that fertilizer can enter to avoid being washed away by rainwater. At the same time, when the driving shaft 2 rotates, the fertilizing component can be driven, so that fertilizer is added to the fertilizing frame 4 in a quantitative manner and sprinkled out through the fertilizer discharging component, ensuring that the amount of fertilizer applied is more accurate, and the fertilizer discharging amount can be adjusted through the fertilizing component so that it can be used for different crops, and the leak-proof component on the base 1 can effectively prevent the fertilizer from leaking and accumulating, ensuring the efficiency of fertilization.

[0075] like Figure 1 , Figure 2 As shown, the piercing assembly includes: two connecting plates 61, symmetrically fixedly installed on the ends of the base 1; two adjusting screws 62, respectively penetrating the top surfaces of the two connecting plates 61, and the adjusting screws 62 are screwed to the penetrations; a mounting frame 63, arranged at the bottom ends of the two adjusting screws 62, and the mounting frame 63 is rotatably connected to the adjusting screws 62; a rotating shaft 64, rotatably installed on the inner wall of the mounting frame 63, and the end of the rotating shaft 64 is connected to the driving shaft 2 through a driven wheel and a synchronous belt transmission; a plurality of driving disks 65, which are distributed in a linear array and sleeved on the outer wall of the rotating shaft 64, and the driving disks 65 are inclined; a plurality of groups of needle bars 66, which are respectively arranged on the outer walls of a plurality of driving disks 65, and the number of needle bars 66 in each group is a plurality and they are distributed in a ring array and fixedly installed on the outer wall of the driving disk 65, and the needle bars 66 are arranged in a conical shape;

[0076] When the base 1 moves with the traction equipment, the rotating wheel 3 drives the driving shaft 2 to rotate, and the rotating shaft 64 can be driven to rotate through the driven wheel and the synchronous belt. When the rotating shaft 64 rotates, it can drive the driving disk 65 and the needle rod 66 thereon to rotate, so as to pierce holes on the moving path of the base 1 to facilitate the entry of fertilizers, and the driving disk 65 is inclined so that the piercing path is curved to facilitate the entry of fertilizers. At the same time, the depth of the piercing holes can be adjusted according to the situation of the fertilizer. When adjusting, the two adjusting screws 62 can be rotated, and the adjusting screws 62 are screwed to the connecting plate 61, so that the height of the mounting frame 63 can be adjusted, thereby realizing the adjustment of the piercing depth.

[0077] like Figures 3 to 6As shown, the fertilizer adding assembly includes: a fertilizer roller 81, which is rotatably mounted on the inner wall of the fertilizer storage box 5 and located between the two sealing seats 7; a plurality of through openings 82, which are evenly opened on the outer wall of the fertilizer roller 81; a plurality of diaphragms 83, which are respectively fixedly mounted on the inner walls of the plurality of through openings 82, and the diaphragms 83 are made of elastic material; a guide sleeve 84, which is fixedly mounted on the inner wall of the fertilizer roller 81; an operating screw 85, which is screwed to the inner wall of the guide sleeve 84, and the end of the operating screw 85 away from the guide sleeve 84 passes through the side of the fertilizer storage box 5 and is movably connected to the penetration; a plurality of jacking mechanisms, which are distributed in a linear array on the operating screw 85;

[0078] like Figures 3 to 6 As shown, the push mechanism includes: a connecting sleeve 86, which is rotatably sleeved on the outer wall of the operating screw 85 through a sliding groove and a slider; a plurality of support rods 87, which are distributed in a ring array and hinged on the outer wall of the connecting sleeve 86; a plurality of top plates 88, which are respectively fixedly mounted on the outer walls of a plurality of diaphragms 83 at positions corresponding to the connecting sleeve 86, and one end of the support rod 87 away from the connecting sleeve 86 is hinged to the top plate 88, and the outer wall of the top plate 88 is adapted to the inner wall of the through hole 82;

[0079] When the driving shaft 2 rotates, the fertilizer roller 81 can be driven to rotate synchronously. When the fertilizer roller 81 rotates, the fertilizer in the fertilizer storage box 5 can enter the diaphragm 83 in the through port 82. As the fertilizer roller 81 rotates, the fertilizer passes through the sealing seat 7 and can fall into the fertilization frame 4 under the action of gravity. The fertilizer output can be adjusted before use. When adjusting, the operating screw 85 can be rotated. The operating screw 85 is threadedly connected to the guide sleeve 84. Therefore, when the operating screw 85 rotates, it can slide along the guide sleeve 84, so as to push the connecting sleeve 86, and then drive the support rod 87 to rotate to push the top plate 88 into the through port 82, so that the diaphragm 83 is stored. At this time, fertilizer cannot be added to the through port 82. The adjustment of the fertilizer addition amount is achieved by controlling the available number of diaphragms 83 in the through port 82.

[0080] like Figure 7 As shown, the fertilizer dispensing assembly includes: a fertilizer spring plate 91, which is slidably mounted on the inner wall of the fertilizer frame 4; two springs 92, which are symmetrically fixedly mounted between the fertilizer spring plate 91 and the inner wall of the fertilizer frame 4; an energized coil 93, which is arranged on the inner wall of the fertilizer frame 4; a metal rod 94, which is arranged through the side of the fertilizer frame 4, the metal rod 94 is slidably connected to the penetration, and the metal rod 94 is located on the inner side of the energized coil 93; a reset magnetic sheet 95, which is fixedly mounted on the side of the fertilizer spring plate 91 at a position relative to the energized coil 93, and the magnetic poles of the reset magnetic sheet 95 and the energized coil 93 are opposite; a linkage mechanism, which is arranged on the top surface of the base 1;

[0081] like Figure 7As shown, the linkage mechanism includes: a crankshaft 96, which is rotatably mounted on the top surface of the base 1, and both ends of the crankshaft 96 are connected to the drive shaft 2 and the fertilizer roller 81 through pulleys and belt transmission; a collar 97, which is rotatably sleeved on the outer wall of the crankshaft 96; a transmission plate 98, which is fixedly mounted on the outer wall of the collar 97, and the end of the transmission plate 98 away from the collar 97 is hinged to the end of the metal rod 94;

[0082] When fertilizer is added to the fertilizing frame 4, the driving shaft 2 synchronously drives the crankshaft 96 to rotate. When the crankshaft 96 rotates, the collar 97 is rotatably connected to the crankshaft 96, and the transmission plate 98 is hinged to the metal rod 94, so that the metal rod 94 can be driven to slide back and forth along the penetration point of the fertilizing frame 4, so that the metal rod 94 is reciprocatedly inserted and pulled out of the energized coil 93. After the energized coil 93 is energized, the metal rod 94 can generate magnetic force when inserted, so as to attract the reset magnetic sheet 95, and the fertilizer spring plate 91 can slide in the direction close to the energized coil 93 and compress the spring 92. After the metal rod 94 is pulled out of the energized coil 93, the energized coil 93 loses its magnetic force. Under the action of the spring 92, the fertilizer spring plate 91 is quickly ejected, and then the fallen fertilizer can be hit, so that the fertilizer is spilled out of the fertilizing frame 4 and into the hole on the ground, thereby realizing the rapid and uniform sprinkling of the fertilizer back and forth.

[0083] like Figure 7 , Figure 8 As shown, the leakage prevention assembly includes: an elastic support cloth 111, which is arranged on the inner wall of the opening 10; a connecting magnetic sheet 112, which is arranged at the center of the bottom surface of the elastic support cloth 111; a transmission shaft 113, which is rotatably mounted on the bottom surface of the base 1; a driven bevel gear 114, which is fixedly mounted on one end of the transmission shaft 113; a driving bevel gear 115, which is fixedly sleeved on the outer wall of the driving shaft 2, and the driving bevel gear 115 is meshed with the driven bevel gear 114; a rotating magnetic sheet 116, which is sleeved on the transmission shaft 113 and is located directly below the connecting magnetic sheet 112;

[0084] For some fertilizers that fail to hit out of the fertilization frame 4, the fertilizers can fall onto the elastic supporting cloth 111 in the opening 10. When the driving shaft 2 rotates, it can drive the driving bevel gear 115 to rotate. The driving bevel gear 115 is engaged with the driven bevel gear 114, and then the driven bevel gear 114 and the transmission shaft 113 can be driven to rotate. When the transmission shaft 113 rotates, it can drive the rotating magnetic piece 116 to rotate. When the rotating magnetic piece 116 rotates to the end relative to the connecting magnetic piece 112, it can generate attractive and repulsive magnetic forces, and then drive the elastic supporting cloth 111 to bounce up, so that the fertilizer on the elastic supporting cloth 111 can be lifted up again so that it can be knocked out by the fertilization spring plate 91.

[0085] The technical solution provided by the present invention can move the entire device to the use position when in use, and connect the base 1 with the traction device through the traction frame 12, and then add the fertilizer to be used into the fertilizer storage box 5. When the traction device drives the base 1 to move, the rotating wheel 3 rotates on the ground to drive the driving shaft 2 to rotate. When the driving shaft 2 rotates, the piercing component can be driven, so that holes are pierced on the ground on the forward path of the base 1, so that the fertilizer can enter and avoid being washed away by rainwater. At the same time, when the driving shaft 2 rotates, the fertilizing component can be driven, so that the fertilizer is quantitatively added to the fertilizing frame 4 and sprinkled out through the fertilizer discharging component, ensuring that the fertilizer application amount is more accurate, and the fertilizer discharging amount can be adjusted by the fertilizing component so as to be used for different crops, and the anti-leakage component on the base 1 can effectively prevent the fertilizer from leaking and accumulating, ensuring the efficiency of fertilization;

[0086] Specifically, when the base 1 moves with the traction equipment, the rotating wheel 3 drives the driving shaft 2 to rotate, which can drive the rotating shaft 64 to rotate through the driven wheel and the synchronous belt. When the rotating shaft 64 rotates, it can drive the driving disk 65 and the needle rod 66 thereon to rotate, so as to pierce holes on the moving path of the base 1 so that fertilizer can enter, and the driving disk 65 is inclined so that the piercing path is curved to facilitate the entry of fertilizer. At the same time, the piercing depth can be adjusted according to the situation of the fertilizer. When adjusting, the two adjusting screws 62 can be rotated. The adjusting screws 62 are screwed to the connecting plate 61, so that the height of the mounting frame 63 can be adjusted, thereby realizing the adjustment of the piercing depth; and when the driving shaft 2 rotates, it can synchronously drive the fertilizer roller 81 to rotate When the fertilizer roller 81 rotates, the fertilizer in the fertilizer storage box 5 can enter the diaphragm 83 in the through port 82. As the fertilizer roller 81 rotates, the fertilizer passes through the sealing seat 7 and can fall into the fertilization frame 4 under the action of gravity. The fertilizer output amount can be adjusted before use. When adjusting, the operating screw 85 can be rotated. The operating screw 85 is screwed with the guide sleeve 84. Therefore, when the operating screw 85 rotates, it can slide along the guide sleeve 84 to push the connecting sleeve 86, thereby driving the support rod 87 to rotate and push the top plate 88 into the through port 82, so that the diaphragm 83 is stored. At this time, fertilizer cannot be added to the through port 82. The adjustment of the fertilizer addition amount is achieved by controlling the available number of diaphragms 83 in the through port 82;

[0087] When fertilizer is added into the fertilizing frame 4, the driving shaft 2 synchronously drives the crankshaft 96 to rotate. When the crankshaft 96 rotates, the collar 97 is rotatably connected to the crankshaft 96, and the transmission plate 98 is hinged to the metal rod 94, so that the metal rod 94 can be driven to slide back and forth along the penetration point with the fertilizing frame 4, so that the metal rod 94 is reciprocatedly inserted and pulled out of the power-carrying coil 93. After the power-carrying coil 93 is energized, the metal rod 94 can generate magnetic force when inserted, so as to attract the reset magnetic sheet 95, and the fertilizer spring plate 91 can slide in the direction close to the power-carrying coil 93 and compress the spring 92. After the metal rod 94 is pulled out of the power-carrying coil 93, the power-carrying coil 93 loses its magnetic force. Under the action of the spring 92, the fertilizer spring plate 91 is quickly ejected, so as to hit the fallen fertilizer, so that the fertilizer is spilled. The fertilization frame 4 enters the hole on the ground, thereby realizing the rapid and uniform spreading of the fertilizer by reciprocating. For some fertilizers that fail to hit the fertilization frame 4, the fertilizers can fall onto the elastic support cloth 111 in the opening 10. When the drive shaft 2 rotates, the driving bevel gear 115 can be driven to rotate. The driving bevel gear 115 is meshed with the driven bevel gear 114, and then the driven bevel gear 114 and the transmission shaft 113 can be driven to rotate. When the transmission shaft 113 rotates, the rotating magnetic sheet 116 can be driven to rotate. When the rotating magnetic sheet 116 rotates to the end relative to the connecting magnetic sheet 112, magnetic forces of attraction and repulsion can be generated, and then the elastic support cloth 111 can be driven to bounce up, so that the fertilizer on the elastic support cloth 111 can be lifted up again so as to be knocked out by the fertilization spring plate 91.
