Description

Technical Field

[0001] The invention relates to the technical field of fertilization, and in particular to a fertilizer uniformly spreading device for wheat planting and a use method thereof. Background Art

[0002] In the field of wheat cultivation, uniform fertilizer spreading is crucial to the healthy growth and final yield of wheat. The traditional method of spreading wheat fertilizer is not only labor-intensive and inefficient, but also difficult to ensure uniformity. Manual operation is easily affected by subjective and physical factors, resulting in uneven distribution of fertilizer in the farmland. Excessive fertilizer in some areas may cause seedling burn, while insufficient fertilizer in some areas will affect the normal growth and development of wheat.

[0003] With the development of agricultural mechanization, various types of fertilizer spreading equipment have emerged, but the existing fertilizer spreading equipment still has many shortcomings. Most equipment lacks an effective unblocking mechanism when dealing with fertilizer agglomeration or uneven particles. During the storage and transportation process, fertilizers are prone to agglomeration due to moisture, extrusion, etc. These agglomerated fertilizers often cause blockage when transported to the spreading device, affecting the continuity and uniformity of the spreading.

When the jet pipe blows air into the discharge pipe, the airflow blown out by the jet pipe is consistent with the falling direction of the fertilizer, which can apply additional thrust to the fertilizer and accelerate the falling speed of the fertilizer in the discharge pipe and the connecting pipe.

[0013] Preferably, the outer side of the wind collecting shell is fixedly connected to the outer side of the discharge pipe, the side wall of the arc-shaped sealing plate is slidably connected to the inner wall of the discharge pipe, the top of the clearing component is rotatably connected to the bottom of the arc-shaped sealing plate, and the rotating component is located at the bottom of the connecting pipe.

The feeding troughs provided on the surface of the dispersion block are of different depths. Due to the different depths of the feeding troughs, the fertilizer will be dispersed at different initial velocities and angles in the horizontal direction after falling from feeding troughs of different depths. The different depths result in different centrifugal forces and frictional forces on the fertilizer, thereby causing differences in the distance and angle of the fertilizer dispersion to the surroundings.

[0021] Step 3: Control the telescopic cylinder to drive the connecting pipe to move through the connecting plate, adjust the distance between the rotating component and the ground and the position of the arc-shaped blocking plate in the discharge pipe, and open the discharge channel;

[0022] Step 4: Start the blower to make the air flow enter the discharge pipe through the air distribution pipe and the air collecting shell, and drive the dredging components to work. The fertilizer falls through the discharge pipe and the connecting pipe, changes direction through the conical diverter block, and reaches the rotating component, where the rotating disk, centrifugal plate and dispersion block cooperate to complete the spreading.

[0023] (III) Beneficial effects

[0024] The present invention provides a fertilizer uniform spreading device for wheat planting and a method for using the device. The device has the following beneficial effects:

[0025] (I) The equipment is equipped with a stirring paddle, and the driving motor is started. The output end drives the stirring shaft to rotate in the mixing box, and the stirring paddle outside the stirring shaft rotates accordingly, so as to fully stir and mix the fertilizer in the mixing box to ensure the uniformity of the fertilizer, prevent the fertilizer from agglomerating, and ensure the looseness of the fertilizer so as to discharge the material smoothly.

[0026] (ii) The equipment is provided with a spreading device. When the telescopic cylinder is extended, the connecting plate drives the connecting pipe in the discharge assembly to slide downward along the inner wall of the discharge pipe. At this time, the connecting pipe can drive the arc-shaped sealing plate to slide downward through the support rod. When the arc-shaped sealing plate is separated from the inner wall of the discharge pipe, the fertilizer can pass through the gap between the arc-shaped sealing plate and the discharge pipe, and finally be discharged from the bottom of the connecting pipe.

[0027] (III) The equipment reserves enough space for the passage of fertilizers while supporting the arc-shaped blocking plate by setting support rods. By setting dredging components and rotating components, when the connecting pipe moves downward, the dredging components and the rotating components move downward synchronously, thereby adjusting the distance of the rotating components from the ground. Under the action of the rotating centrifugal force, the fertilizer is relatively blocked by the ground, the horizontal movement distance is limited, and the spreading range is relatively narrow. By increasing the distance from the ground, the fertilizer has more space for horizontal diffusion, and the spreading range can be widened to meet different spreading needs.

[0028] (IV) The equipment is provided with an arc-shaped sealing plate. The main body of the mixing box is a circular cylindrical structure, and the curvature of the arc-shaped sealing plate just fits with the bottom opening of the mixing box. It can also prevent part of the fertilizer from accumulating at the bottom outlet of the mixing box during the stirring process of the stirring paddle, resulting in uneven mixing.

[0029] (V) The equipment sets up a dredging component and starts the blower, which generates a high-pressure airflow. The airflow is transported to the air collecting shell through the air distribution pipe, and then the airflow is blown into the discharge pipe through the air jet pipe. When the airflow is ejected from the air jet pipe, it can directly blow on the surface of the arc spiral plate in the dredging component, thereby causing the arc spiral plate to drive the rotating shaft to rotate along the inner side of the fixed frame. When the arc spiral plate rotates, it can dredge the fertilizer passing through the connecting pipe to prevent fertilizer blockage.

[0030] (VI) The equipment is equipped with an air jet pipe. The airflow blown out by the air jet pipe is consistent with the falling direction of the fertilizer, which can exert additional thrust on the fertilizer and accelerate the falling speed of the fertilizer in the discharge pipe and the connecting pipe. At the same time, the auxiliary feeding effect of the airflow cooperates with the mechanical stirring of the dredging components. Mechanical dredging combs and stirs the fertilizer, making it easier for the fertilizer to be pushed by the airflow; and the auxiliary feeding effect of the airflow creates better conditions for mechanical dredging and reduces the working resistance of the dredging components. The two work together to ensure that the fertilizer passes through the pipeline smoothly and prevents blockage.

[0031] (VII) The equipment is provided with a conical diverter block. When the fertilizer passes through the connecting pipe, the conical diverter block can change the vertical falling direction of the fertilizer and make it diffuse to all sides. The arc groove opened on its surface can further stir the fertilizer below, enhance the dredging effect of the fertilizer, and ensure that the fertilizer can flow downward continuously and stably. At the same time, the arc spoiler rotates with the conical diverter block. When the fertilizer contacts the arc spoiler, the arc spoiler can make the fertilizer in contact with it move upward during the movement, changing the accumulation trend of the fertilizer. After moving upward, the fertilizer is redistributed and falls under the combined action of gravity and airflow, reducing the risk of blockage.

[0032] (VIII) The equipment is provided with a rotating part. When the fertilizer falls downward to the surface of the turntable in the rotating part, the turntable rotates together with the conical diverter block through the connecting shaft. At this time, part of the fertilizer is thrown to the surroundings and dispersed under the action of the centrifugal force of the centrifugal plate.

[0033] (IX) The equipment is equipped with a dispersion block, and the depth of the troughs on the surface of the dispersion block is inconsistent. Due to the different depths of the troughs, the fertilizer will be dispersed at different initial velocities and angles in the horizontal direction after falling from the troughs of different depths. The different depths lead to different centrifugal forces and friction forces on the fertilizer, which makes the distance and angle of the fertilizer dispersed to the surroundings different. This allows the fertilizer to be spread over a larger range, which helps to cover the wheat planting area more comprehensively and improve the uniformity of fertilizer coverage.

The outer side of the blower 41 is fixedly connected with an air distribution pipe 42, the outer side of the air distribution pipe 42 is fixedly connected with a discharge assembly 43, the outer side of the discharge assembly 43 is fixedly connected with a connecting plate 45, and the top of the connecting plate 45 is fixedly connected with a telescopic cylinder 44; the outer side of the blower 41 is fixedly connected to the outer side of the mixing box 3, the top of the telescopic cylinder 44 is fixedly connected to the bottom of the mixing box 3, the bottom of the mixing box 3 is fixedly connected to the bottom of the discharge assembly 43, the outer side of the discharge assembly 43 is fixedly connected to the inner side of the frame 1, and the discharge assembly 43 and the telescopic cylinder 44 are staggered along the bottom of the mixing box 3.The discharge assembly 43 includes a wind collecting shell 431, the bottom of which is fixedly connected to an air jet pipe 439, the outer wall of which is fixedly connected to a discharge pipe 432, the inner side of the discharge pipe 432 is slidably connected to a connecting pipe 433, the inner side of the connecting pipe 433 is fixedly connected to a fixing frame 434, the top of the fixing frame 434 is fixedly connected to a supporting rod 435, the top of the supporting rod 435 is fixedly connected to an arc-shaped blocking plate 436, the inner side of the fixing frame 434 is rotatably connected to a dredging component 437, the dredging component 437 is used to dredge the fertilizer passing through the connecting pipe 433, the bottom of the dredging component 437 is fixedly connected to a rotating component 438, the rotating component 438 is used to disperse and throw the fertilizer dropped from the bottom of the connecting pipe 433, The outer side of the wind housing 431 is fixedly connected to the outer side of the air distribution pipe 42, the top of the discharge pipe 432 is fixedly connected to the bottom of the mixing box 3, the outer wall of the discharge pipe 432 is fixedly connected to the inner side of the frame 1, the outer wall of the connecting pipe 433 is fixedly connected to the inner side of the connecting plate 45, the outer side of the wind housing 431 is fixedly connected to the outer side of the discharge pipe 432, the side wall of the arc-shaped blocking plate 436 is slidably connected to the inner wall of the discharge pipe 432, the top of the dredging component 437 is rotatably connected to the bottom of the arc-shaped blocking plate 436, and the rotating component 438 is located at the bottom of the connecting pipe 433. When the telescopic cylinder 44 is extended, the connecting plate 45 drives the connecting pipe 433 in the discharge assembly 43 to slide downward along the inner wall of the discharge pipe 432. At this time, the connecting pipe 433 can pass through the support rod 43 5 drives the arc-shaped blocking plate 436 to slide downward. When the arc-shaped blocking plate 436 is separated from the inner wall of the discharge pipe 432, the fertilizer can pass through the gap between the arc-shaped blocking plate 436 and the discharge pipe 432, and finally be discharged from the bottom of the connecting pipe 433. Among them, by providing the support rod 435, while supporting the arc-shaped blocking plate 436, sufficient space is reserved for the passage of the fertilizer. By providing the dredging component 437 and the rotating component 438, when the connecting pipe 433 moves downward, the dredging component 437 and the rotating component 438 move downward synchronously, thereby adjusting the distance of the rotating component 438 from the ground. Under the action of the rotating centrifugal force, the fertilizer is relatively blocked by the ground, the horizontal movement distance is limited, and the throwing range is relatively narrow. The distance from the ground gives the fertilizer a larger space for horizontal diffusion, and the spreading range is widened to meet different spreading needs; by setting the arc-shaped sealing plate 436, the main body of the mixing box 3 is a circular cylindrical structure, and the curvature of the arc-shaped sealing plate 436 just fits the bottom opening of the mixing box 3, and can also prevent part of the fertilizer from accumulating at the bottom discharge port of the mixing box 3 during the stirring process of the stirring paddle 7, resulting in uneven mixing; when the jet pipe 439 blows air into the discharge pipe 432, the airflow blown out by the jet pipe 439 is consistent with the falling direction of the fertilizer, which can apply additional thrust to the fertilizer and accelerate the falling speed of the fertilizer in the discharge pipe 432 and the connecting pipe 433. At the same time, the auxiliary discharge effect of the airflow cooperates with the mechanical stirring of the dredging component 437.Mechanical dredging combs and stirs the fertilizer, making it easier for the fertilizer to be pushed by the airflow; and the auxiliary feeding effect of the airflow creates better conditions for mechanical dredging and reduces the working resistance of the dredging component 437. The two work together to ensure that the fertilizer passes through the pipeline smoothly and prevents blockage.

[0047] The dredging component 437 includes a rotating shaft 371, an arc-shaped spiral plate 372 is fixedly connected to the outer side of the rotating shaft 371, a conical diverter block 373 is fixedly connected to the bottom of the rotating shaft 371, an arc-shaped spoiler plate 374 is fixedly connected to the outer side of the conical diverter block 373, the outer side of the rotating shaft 371 is rotatably connected to the inner side of the fixing frame 434, the top of the rotating shaft 371 is rotatably connected to the bottom of the arc-shaped blocking plate 436, and an arc-shaped groove 375 is opened in the wall of the conical diverter block 373. The blower 41 is started, and the blower 41 generates a high-pressure airflow, which is transported to the air collection shell 431 through the air distribution pipe 42, and then the airflow can be blown into the discharge pipe 432 through the air injection pipe 439. When the airflow is ejected from the air injection pipe 439, it can directly blow on the surface of the arc-shaped spiral plate 372 in the dredging component 437, so that the arc-shaped spiral plate 372 drives the rotating shaft 37 The arc-shaped spiral plate 372 rotates along the inner side of the fixing frame 434, and the fertilizer passing through the connecting pipe 433 can be dredged when the arc-shaped spiral plate 372 rotates to prevent the fertilizer from being blocked. By setting the conical diverter block 373, when the fertilizer passes through the connecting pipe 433, the conical diverter block 373 can change the vertical falling direction of the fertilizer, so that it can be diffused to all sides, and the arc-shaped groove 375 opened on the surface can further stir the fertilizer below, enhance the dredging effect of the fertilizer, and ensure that the fertilizer can flow downward continuously and stably. At the same time, the arc-shaped spoiler 374 rotates together with the conical diverter block 373. When the fertilizer contacts the arc-shaped spoiler 374, the arc-shaped spoiler 374 can make the fertilizer in contact with it move upward during the movement, thereby changing the accumulation trend of the fertilizer. The fertilizer after moving upward is redistributed and falls under the combined action of gravity and airflow, thereby reducing the risk of blockage.

[0048] The rotating component 438 includes a rotating disk 381, a connecting shaft 383 is fixedly connected at the center of the rotating disk 381, a centrifugal plate 382 is fixedly connected to the top of the rotating disk 381, a dispersion block 384 is fixedly connected to the bottom of the connecting shaft 383, the top of the connecting shaft 383 is fixedly connected to the bottom of the conical diversion block 373, the centrifugal plates 382 are arranged in a ring along the central axis of the centrifugal plates 382, ​​and a drop groove 385 is opened in the wall of the dispersion block 384. When the fertilizer falls downward to the surface of the rotating disk 381 in the rotating component 438, When the rotating disk 381 rotates with the conical diverter block 373 through the connecting shaft 383, part of the fertilizer is thrown around and dispersed under the centrifugal force of the centrifugal plate 382, ​​while the rest of the fertilizer falls down from the center of the rotating disk 381 and contacts the dispersion block 384; wherein, the depth of the drop groove 385 opened on the surface of the dispersion block 384 is inconsistent. Due to the different depths of the drop groove 385, the fertilizer will be dispersed at different initial velocities and angles in the horizontal direction after falling from the drop groove 385 of different depths. The different depths result in different centrifugal forces and friction forces on the fertilizer, which makes the distance and angle of the fertilizer dispersed around different. This allows the fertilizer to be scattered over a larger range, which helps to cover the wheat planting area more comprehensively and improve the uniformity of fertilizer coverage.

[0049] Working principle: The fertilizer uniform spreading equipment uses the frame 1 as the supporting structure, and the moving wheels 2 at the bottom facilitate the movement of the equipment in the farmland. When working, put the fertilizer into the mixing box 3 from the opening at the top of the mixing box 3, and then start the driving motor 5, and its output end drives the stirring shaft 6 to rotate in the mixing box 3, and the stirring paddle 7 outside the stirring shaft 6 rotates accordingly, and the fertilizer in the mixing box 3 is fully stirred and mixed to ensure the uniformity of the fertilizer, and also to prevent the fertilizer from agglomerating and ensure the looseness of the fertilizer for smooth discharge.

[0050] After the mixing is completed, the spreading device 4 starts to work. When the telescopic cylinder 44 is extended, the connecting plate 45 drives the connecting pipe 433 in the discharge assembly 43 to slide downward along the inner wall of the discharge pipe 432. At this time, the connecting pipe 433 can drive the arc-shaped sealing plate 436 to slide downward through the support rod 435. When the arc-shaped sealing plate 436 is separated from the inner wall of the discharge pipe 432, the fertilizer can pass through the gap between the arc-shaped sealing plate 436 and the discharge pipe 432, and finally be discharged from the bottom of the connecting pipe 433.

[0051] Among them, by setting the support rod 435, while supporting the arc-shaped blocking plate 436, sufficient space is reserved for the passage of fertilizer. By setting the clearing component 437 and the rotating component 438, when the connecting pipe 433 moves downward, the clearing component 437 and the rotating component 438 move downward synchronously, thereby the distance from the ground of the rotating component 438 can also be adjusted. Under the action of the rotating centrifugal force, the fertilizer is relatively blocked by the ground, the horizontal movement distance is limited, and the spreading range is relatively narrow; by increasing the distance from the ground, the fertilizer obtains a larger space for horizontal diffusion, and the spreading range is widened to meet different spreading needs.

[0052] By setting the arc-shaped sealing plate 436, the main body of the mixing box 3 is a circular cylindrical structure, and the curvature of the arc-shaped sealing plate 436 just fits with the bottom opening of the mixing box 3, which can also prevent part of the fertilizer from accumulating at the bottom outlet of the mixing box 3 during the stirring process of the stirring paddle 7, resulting in uneven mixing.

[0053] During this process, the blower 41 is started to generate a high-pressure airflow, which is transported to the air collecting shell 431 through the air distribution pipe 42, and then the airflow can be blown into the discharge pipe 432 through the jet pipe 439. When the airflow is ejected from the jet pipe 439, it can directly blow on the surface of the arc spiral plate 372 in the dredging component 437, so that the arc spiral plate 372 drives the rotating shaft 371 to rotate along the inner side of the fixed frame 434. When the arc spiral plate 372 rotates, the fertilizer passing through the connecting pipe 433 can be dredged to prevent fertilizer blockage.

[0054] When the jet pipe 439 blows air into the discharge pipe 432, the airflow blown out by the jet pipe 439 is consistent with the falling direction of the fertilizer, which can exert additional thrust on the fertilizer and accelerate the falling speed of the fertilizer in the discharge pipe 432 and the connecting pipe 433. At the same time, the auxiliary feeding effect of the airflow cooperates with the mechanical stirring of the dredging component 437. Mechanical dredging combs and stirs the fertilizer, making it easier for the fertilizer to be pushed by the airflow; and the auxiliary feeding effect of the airflow creates better conditions for mechanical dredging, reducing the working resistance of the dredging component 437. The two work together to ensure that the fertilizer passes through the pipeline smoothly and prevents blockage.

[0055] By setting the conical diverter block 373, when the fertilizer passes through the connecting pipe 433, the conical diverter block 373 can change the vertical falling direction of the fertilizer and make it diffuse around. The arc groove 375 opened on its surface can further stir the fertilizer below, enhance the dredging effect of the fertilizer, and ensure that the fertilizer can flow downward continuously and stably. At the same time, the arc spoiler 374 rotates with the conical diverter block 373. When the fertilizer contacts the arc spoiler 374, the arc spoiler 374 can make the fertilizer in contact with it move upward during the movement, thereby changing the accumulation trend of the fertilizer. After moving upward, the fertilizer is redistributed and falls under the combined action of gravity and airflow, thereby reducing the risk of blockage.

[0056] When the fertilizer falls downward to the surface of the rotating disk 381 in the rotating component 438, the rotating disk 381 rotates together with the conical diverter block 373 through the connecting shaft 383. At this time, part of the fertilizer is thrown to the surroundings and dispersed under the centrifugal force of the centrifugal plate 382, ​​while the rest of the fertilizer falls downward from the center of the rotating disk 381 and contacts the dispersion block 384.

[0057] Among them, the depths of the drop grooves 385 opened on the surface of the dispersion block 384 are inconsistent. Due to the different depths of the drop grooves 385, the fertilizer will be dispersed at different initial velocities and angles in the horizontal direction after falling from the drop grooves 385 of different depths. The different depths cause the fertilizer to obtain different centrifugal forces and friction forces, thereby causing differences in the distances and angles at which the fertilizer is dispersed to the surroundings. This allows the fertilizer to be spread over a larger range, which helps to more comprehensively cover the wheat planting area and improve the uniformity of fertilizer coverage.

[0058] Example 2: Please refer to Figure 1 - Figure 8 The present invention provides a technical solution: based on the first embodiment, a method for using a fertilizer uniformly spreading device for wheat planting, based on the above-mentioned fertilizer uniformly spreading device for wheat planting, comprises the following steps:

[0059] Step 1: Move the spreading device to the wheat planting area to be fertilized, ensure that the moving wheel 2 firmly supports the device, and then fill the fertilizer into the mixing box 3 through the top opening of the mixing box 3;

[0060] Step 2: Start the driving motor 5, drive the stirring shaft 6 to rotate, and drive the stirring paddle 7 to fully stir and mix the fertilizer in the mixing box 3;

[0061] Step 3: Control the telescopic cylinder 44 to drive the connecting pipe 433 to move through the connecting plate 45, adjust the distance between the rotating component 438 and the ground and the position of the arc-shaped blocking plate 436 in the discharge pipe 432, and open the discharge channel;

[0062] Step 4: Start the blower 41, so that the air flows through the air distribution pipe 42 and the air collecting shell 431 into the discharge pipe 432, driving the dredging component 437 to work. The fertilizer falls through the discharge pipe 432 and the connecting pipe 433, changes direction through the conical diverter block 373, and reaches the rotating component 438, and is scattered by the cooperation of the rotating disk 381, the centrifugal plate 382 and the dispersion block 384.
