Description

Technical Field

[0001] The invention belongs to the technical field of oil crop planting, in particular to an oil crop planting fertilization device. Background Art

[0002] Agricultural fertilization refers to the agricultural technical measure of applying fertilizers to the soil or spraying them on plants to provide the nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, improve soil fertility and increase economic benefits. During the planting process of oil crops, fertilization devices are usually used to achieve the above purposes.

[0003] A Chinese patent with publication number CN206533717U discloses an oil crop planting and fertilizing device, including a carrier vehicle, a planting mechanism and a fertilizing mechanism located on the carrier vehicle, and a power mechanism connected to the planting mechanism, wherein the planting mechanism includes a plurality of digging shovels, a soil return push plate located behind the digging shovel, a digging push rod connected to the digging shovel, and a seed seeder; the fertilizing mechanism includes a fertilizer tank, a fertilizer pressure pump connected to the fertilizer tank, and a fertilizer probe connected to the fertilizer pressure pump and fixed on the digging push rod; when working, the hydraulic push rod above the digging push rod pushes downward, and the digging push rod drives the digging shovel and the fertilizer probe to move downward; the stirring motor of the fertilizer tank stirs the fertilizer outlet solenoid valve to open, and the pressure sensor of the weighing plate calculates the weight of the fertilizer, and then flows down to the fertilizer pressure pump and is pumped to the downward pointed fertilizer probe, and the pumping prevents the fertilizer probe from being blocked by mud during the downward movement, and after fertilization is completed, the next depth of the fertilizer probe is deeper than the digging shovel, which will not affect seed germination. The horizontal hydraulic cylinder pushes the digging shovel forward to dig the soil, and the seeds are planted under the seed drill.

[0004] In the current existing technology, a fertilizer pressure pump is used to prevent the fertilizer probe from being blocked by mud during downward movement, and most of the fertilizer can be unblocked. However, during the fertilization process, the fertilizer will melt under the sunlight, causing some soil to adhere to the bottom of the fertilizer tank. If it is not cleaned in time, the water and soil containing the fertilizer will corrode the fertilizer tank, causing the fertilizer tank to rust and break.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 8 As shown, an oil crop planting and fertilizing device according to an embodiment of the present invention comprises: a frame 1; a silo 2, fixedly connected to the frame 1; three lower hoppers 210, fixedly connected to the bottom of the silo 2 in sequence; a power mechanism, arranged on the frame 1, for driving the frame 1 to move; a crushing mechanism, arranged in the silo 2, for crushing agglomerated fertilizers; a hammer mechanism; the hammer mechanism comprises a tooth plate 4 arranged on the outer side of the lower hopper 210, and three connecting plates 47 are fixedly connected to a side wall of the tooth plate 4 close to the lower hopper 210; the connecting plate 4 7 are all fixedly connected with a striking hammer 43; a spring 48 is sleeved on the outer side of the striking hammer 43, and the two ends of the spring 48 are respectively fixedly connected to the connecting plate 47 and the lower hopper 210; a mounting plate 45 is fixedly connected to the outer side wall of the middle lower hopper 210, and a third motor 46 is fixedly connected to the inner side wall of the mounting plate 45; the output shaft of the third motor 46 is rotatably connected to the lower hopper 210 through a bearing, and is fixedly connected with a special-shaped gear 44, and the special-shaped gear 44 is meshed with the tooth plate 4; the striking hammer 43 is made of rubber material.

[0038] Oil crops need to be fertilized during planting. The fertilizer is placed in the silo 2. Under the action of gravity, it will eventually be discharged through the lower hopper 210 for fertilization. The frame 1 is driven by the power mechanism to expand the scope of fertilization. Since the fertilizer will melt under the sunlight, some soil will adhere to the bottom of the lower hopper 210. If it is not cleaned in time, the water and soil with fertilizer will corrode the lower hopper 210, causing the lower hopper 210 to rust and break. When the hammer mechanism provided by the present invention is in use, the third motor 46 is regularly turned on, and the third motor 46 drives the special-shaped gear 44 to rotate through the output shaft, and the special-shaped gear 4 4 is meshed with the tooth plate 4, and the tooth plate 4 is driven to move by the special-shaped gear 44, and the tooth plate 4 drives the connecting plate 47 and the impact hammer 43 to move, and the spring 48 is stretched. When the special-shaped gear 44 rotates and no longer meshes with the tooth plate 4, the meshing of the tooth plate 4 is released. Under the action of the spring 48, the impact hammer 43, the connecting plate 47 and the tooth plate 4 are quickly reset, and the impact hammer 43 hits the lower hopper 210 to complete one impact. At this time, the special-shaped gear 44 rotates again to mesh with the tooth plate 4 to perform a second impact. The reciprocating impact knocks the soil and fertilizer on the inner wall of the lower hopper 210 off, thereby achieving the effect of quickly cleaning the inner wall of the lower hopper 210.

[0039] like Figures 2 to 5As shown, two partitions 21 are fixedly connected to the inner wall of the silo 2, and the two partitions 21 are respectively adapted to the lower hopper 210, and a top plate 22 is fixedly connected to the two partitions 21. The crushing mechanism includes three rotating rods 23 rotatably connected to the bottom of the top plate 22 through bearings, and the outer side walls of the rotating rods 23 are fixedly connected to multiple stirring rods 24, and the tops of the rotating rods 23 are fixedly connected to worms 27. The silo 2 is rotatably connected to three worms 27 through bearings, and the three worms 27 are connected together, and the three worms 27 are connected to adjacent The worm gear 29 is meshed with each other, and a first motor 28 is fixedly connected to the outer wall of the silo 2, and the output shaft of the first motor 28 is fixedly connected to one end of the worm 27; the bottom end of the rotating rod 23 is fixedly connected to a spiral blade 25, and the spiral blades 25 are all arranged inside the lower hopper 210; three protective boxes 26 are fixedly connected to the bottom of the top plate 22, and the worm gear 29 and the worm 27 are respectively arranged inside the protective boxes 26; three protective boxes 26 are fixedly connected to the bottom of the top plate 22, and the worm gear 29 and the worm 27 are respectively arranged inside the protective boxes 26.

[0040] Fertilizers may agglomerate after long-term accumulation. After being poured into the silo 2, it is not only inconvenient to fall, but also may block the lower hopper 210. When the crushing mechanism provided by the present invention is used, the lower hopper 210 is blocked to pour fertilizer, and then the first motor 28 is turned on. The first motor 28 drives the worm 27 to rotate through the output shaft, drives the worm wheel 29 to rotate through the worm 27, drives the rotating rod 23 to rotate through the worm wheel 29, and drives the stirring rod 24 to rotate through the rotating rod 23. The agglomerated fertilizer is easily crushed through the stirring rod 24. At the same time, if several fertilizers are mixed, the stirring rod 24 is used to mix the fertilizers evenly, which is conducive to uniform soil fertilization; the rotating rod 23 drives the spiral blade 25 to rotate when rotating, and the spiral blade 25 is used to dredge the fertilizer in the lower hopper 210 to prevent the fertilizer from accumulating at the outlet of the lower feeding port, affecting the efficiency and uniformity of fertilization; a protective box 26 is provided to protect the worm wheel 29 and the worm 27 to prevent the worm wheel 29 and the worm 27 from being corroded by the fertilizer and affecting the rotation.

[0041] like Figure 6 and Figure 7 As shown, a blocking mechanism is provided at the bottom of the lower hopper 210, and the blocking mechanism includes two blocking plates 3. Two fixing plates 31 are fixedly connected to the outer walls on both sides of the lower hopper 210. A bidirectional ball screw 32 is rotatably connected between two adjacent fixing plates 31 through bearings, and the blocking plates 3 are threadedly connected to the bidirectional ball screw 32; one end of the bidirectional ball screw 32 extends to the outside of the fixing plate 31 and is fixedly connected to a rotating wheel 34, and a belt 35 is sleeved between the two rotating wheels 34; a second motor 33 is fixedly connected to one of the fixing plates 31, and the output shaft of the second motor 33 is fixedly connected to the end of the bidirectional ball screw 32 away from the rotating wheel 34.

[0042] When the fertilizer is being stirred, the lower hopper 210 needs to be blocked. For different fertilizers and different soils, the amount of fertilizer applied needs to be adjusted. When the blocking mechanism provided by the present invention is in use, by turning on the second motor 33, the second motor 33 drives the bidirectional ball screw 32 to rotate through the output shaft. When the bidirectional ball screw 32 rotates, it drives the connected wheel 34 to rotate. The wheel 34 drives another wheel 34 to rotate through the belt 35. The other wheel 34 drives the connected bidirectional ball screw 32 to rotate. The two bidirectional ball screws 32 rotate synchronously and drive the two blocking plates 3 to move in opposite directions. The distance between the two blocking plates 3 is adjusted to adjust the amount of fertilizer applied and the opening and closing of the blocking plates 3 can be adjusted.

[0043] like Figure 8 As shown, two limiting openings 42 are formed on the tooth plate 4 , wherein a limiting block 41 is fixedly connected to the outer side walls of the two lower hoppers 210 ; the limiting blocks 41 slide in the corresponding limiting openings 42 , respectively.

[0044] When the limiting block 41 provided by the present invention is in use, the tooth plate 4 is in motion, and the limiting block 41 slides in the limiting opening 42 , so that the limiting block 41 limits the tooth plate 4 in a horizontal direction.

[0045] like Figure 2 As shown, the power mechanism includes two front wheels 11, two rear wheels 12 and an engine group 14. The engine group 14 is arranged on the top of the frame 1; the engine group 14 is connected to the front wheels 11 through a transmission belt.

[0046] When the engine group 14 provided by the present invention is in use and the frame 1 needs to move, the engine group 14 is turned on, and the engine group 14 drives the front wheels 11 to rotate through the transmission belt, thereby driving the frame 1 to move on a designated route.

[0047] like Figure 1 As shown, four fixing columns 5 are provided between the front wheels 11 and the lower hopper 210 , and plow blocks 51 are fixedly connected to the bottoms of the fixing columns 5 .

[0048] When the plow block 51 provided by the present invention is in use, the frame 1 drives the fixed column 5 and the plow block 51 forward during the forward movement of the frame 1, and the land is plowed and loosened by the plow block 51, and then fertilizer is applied, and fresh and moist soil is conducive to the dissolution of fertilizer.

[0049] like Figure 2 As shown, two fixing frames 6 are provided between the lower hopper 210 and the rear wheel 12, and a crushing roller 61 is rotatably connected between the two fixing frames 6 via a bearing.

[0050] When the plow block 51 provided by the present invention is in use, the frame 1 drives the crushing roller 61 to rotate during the forward process, and the crushing roller 61 crushes and backfills the soil after plowing and fertilizing, so that the fertilizer is fully buried under the soil to prevent the nitrogen in the fertilizer from volatilizing under sunlight, which not only reduces the quality of the fertilizer but also affects the environment.

[0051] like Figure 1 As shown, a handlebar 13 is fixedly connected to one end of the frame 1 away from the engine block 14 ; and anti-slip sleeves 15 are fixedly connected to both ends of the handlebar 13 .

[0052] When the anti-skid cover 15 provided by the present invention is used, it is inconvenient to hold the handlebar 13 due to sweating hands after long-term labor, which brings safety hazards to the staff. By providing the anti-skid cover 15, friction is increased, the handlebar 13 is held tightly, and the stability of the forward movement is guaranteed.

[0053] Working principle: When the hammer mechanism provided by the present invention is in use, the third motor 46 is turned on periodically, and the third motor 46 drives the special-shaped gear 44 to rotate through the output shaft, and the special-shaped gear 44 is meshed with the tooth plate 4, and the tooth plate 4 is driven to move through the special-shaped gear 44, and the tooth plate 4 drives the connecting plate 47 and the impact hammer 43 to move, and the spring 48 is stretched. When the special-shaped gear 44 rotates and no longer meshes with the tooth plate 4, the meshing of the tooth plate 4 is released, and under the action of the spring 48, the impact hammer 43, the connecting plate 47 and the tooth plate 4 are quickly reset, and the impact hammer 43 hits the lower hopper 210 to complete an impact. At this time, the special-shaped gear 44 rotates again to mesh with the tooth plate 4 for a second impact. The reciprocating impact knocks the soil and fertilizer on the inner wall of the lower hopper 210 off, thereby achieving the effect of quickly cleaning the inner wall of the lower hopper 210; during the movement of the tooth plate 4, the limit block 41 slides in the limit opening 42, and the limit block 41 limits the tooth plate 4 in the horizontal direction;

[0054] When the crushing mechanism provided by the present invention is used, the lower hopper 210 is blocked and the fertilizer is poured into it. Then, by turning on the first motor 28, the first motor 28 drives the worm 27 to rotate through the output shaft, the worm 27 drives the worm wheel 29 to rotate, the worm wheel 29 drives the rotating rod 23 to rotate, and the rotating rod 23 drives the stirring rod 24 to rotate. The stirring rod 24 is used to crush the agglomerated fertilizer. At the same time, if several fertilizers are mixed, the stirring rod 24 is used to mix the fertilizers evenly, which is beneficial to the uniform fertilization of the soil; when the rotating rod 23 rotates, the spiral blade 25 is driven to rotate, and the spiral blade 25 is used to dredge the fertilizer in the lower hopper 210, so as to prevent the fertilizer from accumulating at the outlet of the lower feeding port and affecting the efficiency and uniformity of fertilization; a protective box 26 is provided to protect the worm wheel 29 and the worm 27, so as to prevent the worm wheel 29 and the worm 27 from being corroded by the fertilizer and affecting the rotation;

[0055] When the blocking mechanism provided by the present invention is in use, by turning on the second motor 33, the second motor 33 drives the bidirectional ball screw 32 to rotate through the output shaft, and the bidirectional ball screw 32 drives the connected rotating wheel 34 to rotate when rotating, and the rotating wheel 34 drives another rotating wheel 34 to rotate through the belt 35, and the other rotating wheel 34 drives the connected bidirectional ball screw 32 to rotate, and the two bidirectional ball screws 32 rotate synchronously to drive the two blocking plates 3 to move in opposite directions, and the distance between the two blocking plates 3 is adjusted to adjust the amount of fertilizer application and the opening and closing of the blocking plates 3;

[0056] The frame 1 drives the fixed column 5 and the plow block 51 forward, and the land is plowed and loosened by the plow block 51, and then fertilizer is applied. The fresh and moist soil is conducive to the melting of the fertilizer. During the forward movement of the frame 1, the crushing roller 61 is driven to rotate, and the soil after plowing and fertilization is crushed and backfilled by the crushing roller 61, so that the fertilizer is fully buried under the soil to prevent the nitrogen in the fertilizer from volatilizing under the sunlight, which not only reduces the quality of the fertilizer but also affects the environment.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
