Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a fertilizer spreading blade module for a fertilizer spreader. Background Technology

[0002] In modern agriculture, the requirements for fertilization precision are becoming increasingly higher. However, traditional fertilization methods are often extensive, resulting in uneven fertilizer distribution, low fertilizer utilization, and uneven crop growth.

[0003] Traditional fertilizer spreaders typically have fixed blade angles, making it impossible to control the direction and range of fertilizer application based on terrain. When encountering irregularly shaped farmland, such as plots with corners or sloping edges, fertilizer spreaders with fixed blade angles cannot flexibly adjust the direction of fertilizer application, resulting in uneven fertilization at the edges of plots or in areas with special shapes. Furthermore, the inability to adjust the blade angle means that fertilizer cannot be accurately applied to the target crop area, leading to fertilizer waste or fertilizer contamination in areas where fertilization is unnecessary.

[0004] Traditional fertilizer spreaders have fixed blade angles, making it difficult to spread fertilizer beyond the width of the truck bed. This often results in fertilizer being spread only around the sides of the truck bed. When dealing with large areas that need fertilizer spreading, the limited spreading range requires the vehicle to travel back and forth multiple times, leading to low efficiency in fertilization operations. Furthermore, since different fertilizer particles have different sizes and flow characteristics, an unsuitable blade angle may cause small fertilizer particles to be blown away by the wind or concentrated in a small area, while large fertilizer particles may not have enough spreading distance and range, resulting in uneven fertilizer distribution. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer-spraying blade module for a fertilizer spreader to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fertilizer spreading blade module for a fertilizer spreader includes a rotating shaft, a spreading mechanism, and an angle adjustment mechanism. Several spreading mechanisms are provided, and the rotating shaft and several spreading mechanisms are rotatably connected. The rotating shaft is provided with a mounting groove, and the angle adjustment mechanism is placed in the mounting groove. The several spreading mechanisms and the angle adjustment mechanism are connected by a transmission.

[0008] The rotating shaft drives the spreading mechanism to rotate, causing the fertilizer to be spread out. The angle adjustment mechanism, located in the installation slot, changes the angle of the spreading mechanism's blades, controlling the spreading range so that it can exceed the width of the truck bed. By changing the angle of the blades in the spreading mechanism through the angle adjustment mechanism, the direction of fertilizer spreading can be precisely controlled, thus ensuring that the fertilizer is accurately spread in the designated plots. This avoids insufficient fertilization in the edge areas due to the fixed spreading blades failing to spread fertilizer to the edge areas.

[0009] Furthermore, the scattering mechanisms are staggered along the rotation axis.

[0010] By distributing the spreading mechanism in an alternating pattern along the rotation axis, the fertilizer is subjected to centrifugal force at different positions and angles. This effectively prevents small fertilizer particles from concentrating too much in one area during the spreading process. For large fertilizer particles, it ensures that they have enough space to be thrown out, avoiding collisions or blockages within the spreading mechanism. It also prevents fertilizer from concentrating in a specific area or direction, allowing the fertilizer to be spread out more evenly.

[0011] Furthermore, the spreading mechanism includes a first rotating shaft, a limiting block, a connecting plate, and spreading blades. The first rotating shaft is rotatably connected to the rotating shaft, the limiting block is fixedly connected to the first rotating shaft, the connecting plate is fixedly connected to the first rotating shaft, and the spreading blades are fixedly connected to the connecting plate.

[0012] The rotational connection between the No. 1 rotating shaft and the rotary shaft allows the connecting plate, which is fixedly connected to the No. 1 rotating shaft, to rotate. This, in turn, allows the spreading blades fixed on the connecting plate to change their angle, thus enabling precise control of the fertilizer spreading direction. The limiting block prevents the No. 1 rotating shaft from moving axially. By changing the angle of the spreading blades, the spreading range can exceed the width of the truck bed, reducing the number of times the fertilizer spreader has to work back and forth in the field, thereby improving fertilization efficiency.

[0013] Furthermore, the angle adjustment mechanism includes a motor, a second rotating shaft, a support base, a first bevel gear, and a second bevel gear. The motor is placed in the mounting slot, and the motor output end is fixedly connected to the second rotating shaft. The support base is placed in the mounting slot, and the support base is rotatably connected to the second rotating shaft. There are several first bevel gears, and the second rotating shaft is driven by the first bevel gear. There are several second bevel gears, and the first and second bevel gears mesh with each other. The second bevel gear is driven by the first rotating shaft.

[0014] The motor output end and support base are fixed to both sides of the second rotating shaft, enabling the motor to drive the second rotating shaft to rotate along its axis. The second rotating shaft is connected to the first bevel gear via a keyway transmission, causing the first bevel gear to drive the second bevel gear to rotate. The second bevel gear is then connected to the first rotating shaft via a keyway transmission, causing the first rotating shaft to rotate. This, in turn, causes the connecting plate to drive the spreading blades to rotate, thereby adjusting the angle of the spreading blades. Power is transmitted through the motor, allowing the spreading blades to quickly adjust their angle. This ensures fertilization accuracy while increasing the speed of fertilization operations and reducing the time required for the entire fertilization process.

[0015] Furthermore, the spreading blades are provided with inclined surfaces, and the angle between the two inclined surfaces and the connecting plate is an acute angle.

[0016] The spreading blades have inclined surfaces, and the angle between the two inclined surfaces and the connecting plate is an acute angle. This makes the spreading blades gradually larger from the connecting plate outwards, which gradually enhances the effect of centrifugal force on the blades, thus making the fertilizer spread more efficiently.

[0017] Furthermore, multiple triangles are provided between the far ends of the two inclined planes.

[0018] By setting multiple triangles between the far ends of the two inclined planes, the triangular areas increase the contact area for agitating the fertilizer when the spreading blades rotate. At the same time, the triangles exert an impact force on the fertilizer, effectively preventing the fertilizer from clumping or agglomerating, thus ensuring that the fertilizer is more dispersed and distributed more evenly when it leaves the blades.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The motor drives the second rotating shaft to rotate along its axis, causing the first bevel gear to drive the second bevel gear to rotate, which in turn rotates the first rotating shaft. The connecting plate then drives the spreading blades to rotate, allowing for flexible adjustment of the spreading blade angle. This enables precise control of the fertilizer spreading direction and the spreading range, allowing the spreader to exceed the width of the truck bed. This reduces the number of times the fertilizer spreader needs to move back and forth in the field, thereby improving fertilization efficiency.

[0021] 2. By transmitting power through a motor, the spreading blades can quickly adjust their angle, thereby ensuring the accuracy of fertilization while increasing the speed of fertilization operations and reducing the time required for the entire fertilization process.

[0022] 3. By using a staggered distribution of the spreading mechanism along the rotating axis and by flexibly adjusting the angle of the spreading blades with a motor, it effectively prevents small fertilizer particles from being too concentrated in a certain area during the spreading process. For large fertilizer particles, it ensures that they have enough space to be thrown out, avoiding collisions or blockages between large fertilizer particles inside the spreading mechanism. It also prevents fertilizer from being concentrated in a specific area or direction, allowing the fertilizer to be spread out more evenly. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a fertilizer spreading blade module for a fertilizer spreader. The fertilizer spreading blade module for a fertilizer spreader includes a rotating shaft 1, a spreading mechanism 2, and an angle adjustment mechanism 3. There are several spreading mechanisms 2. The rotating shaft 1 and several spreading mechanisms 2 are rotatably connected. The rotating shaft 1 is provided with an installation groove 11. The angle adjustment mechanism 3 is placed in the installation groove 11. The several spreading mechanisms 2 and the angle adjustment mechanism 3 are connected by transmission.

[0030] The rotation of the rotating shaft 1 drives the spreading mechanism 2 to rotate, causing the fertilizer to be spread out. The angle adjustment mechanism 3, placed in the mounting groove 11, changes the angle of the blades of the spreading mechanism 2, controlling the spreading range so that it can exceed the width of the truck bed. By changing the angle of the blades in the spreading mechanism 2 through the angle adjustment mechanism 3, the spreading direction of the fertilizer can be precisely controlled, so that the fertilizer is accurately spread in the designated plot, avoiding insufficient fertilization in the edge areas due to the fixed fertilizer spreading blades failing to spread the fertilizer to the edge areas.

[0031] like Figure 3 and Figure 4As shown, the scattering mechanism 2 is staggered along the rotation axis 1.

[0032] By distributing the spreading mechanism 2 in an alternating pattern along the rotating axis 1, the fertilizer is subjected to centrifugal force at different positions and angles. This effectively prevents small fertilizer particles from being too concentrated in a certain area during the spreading process. For large fertilizer particles, it ensures that they have enough space to be thrown out, avoiding collisions or blockages between large fertilizer particles inside the spreading mechanism 2. It also prevents fertilizer from being concentrated in a specific area or direction, allowing the fertilizer to be spread out more evenly.

[0033] like Figure 2 As shown, the scattering mechanism 2 includes a first rotating shaft 21, a limiting block 22, a connecting plate 23, and a scattering blade 24. The first rotating shaft 21 is rotatably connected to the rotating shaft 1, the limiting block 22 is fixedly connected to the first rotating shaft 21, the connecting plate 23 is fixedly connected to the first rotating shaft 21, and the scattering blade 24 is fixedly connected to the connecting plate 23.

[0034] The first rotating shaft 21 and the rotating shaft 1 are rotatably connected, allowing the connecting plate 23, which is fixedly connected to the first rotating shaft 21, to rotate. This allows the spreading blades 24, which are fixed on the connecting plate 23, to change their angle, thereby precisely controlling the direction of fertilizer spreading. The limiting block 22 prevents the first rotating shaft 21 from moving axially. By changing the angle of the spreading blades 24, the spreading range can exceed the width of the truck bed, reducing the number of times the fertilizer spreader has to work back and forth in the field, thus improving fertilization efficiency.

[0035] like Figure 2 As shown, the angle adjustment mechanism 3 includes a motor 31, a second rotating shaft 32, a support base 33, a first bevel gear 34, and a second bevel gear 35. The motor 31 is placed in the mounting groove 11, and the output end of the motor 31 is fixedly connected to the second rotating shaft 32. The support base 33 is placed in the mounting groove 11, and the support base 33 is rotatably connected to the second rotating shaft 32. There are several first bevel gears 34, and the second rotating shaft 32 is drivenly connected to the first bevel gear 34. There are several second bevel gears 35, and the first bevel gear 34 and the second bevel gear 35 mesh. The second bevel gear 35 is drivenly connected to the first rotating shaft 21.

[0036] The second rotating shaft 32 is fixed on both sides by the output end of the motor 31 and the support base 33, so that the motor 31 can drive the second rotating shaft 32 to rotate along its axis. The second rotating shaft 32 is connected to the first bevel gear 34 by a keyway, so that the first bevel gear 34 drives the second bevel gear 35 to rotate. The second bevel gear 35 is connected to the first rotating shaft 21 by a keyway, so that the first rotating shaft 21 rotates, thereby causing the connecting plate 23 to drive the spreading blade 24 to rotate, thereby adjusting the angle of the spreading blade 24. The motor 31 transmits power so that the spreading blade 24 can quickly adjust the angle, thereby improving the speed of fertilization while ensuring the accuracy of fertilization and reducing the time required for the entire fertilization process.

[0037] like Figure 4 As shown, the scattering blade 24 has an inclined surface 241, and the angle between the two inclined surfaces 241 and the connecting plate 23 is an acute angle.

[0038] The spreading blade 24 has an inclined surface 241, and the angle between the two inclined surfaces 241 and the connecting plate 23 is an acute angle, so that the spreading blade 24 gradually becomes larger from the connecting plate 23 outwards, thereby gradually enhancing the effect of centrifugal force on the blade and making the fertilizer spread more efficiently.

[0039] like Figure 4 As shown, there are multiple triangles between the far ends of the two inclined planes.

[0040] By setting multiple triangles between the far ends of the two inclined planes, when the spreading blade 24 rotates, the triangular area increases the contact area for agitating the fertilizer. At the same time, the triangles exert an impact force on the fertilizer, effectively preventing the fertilizer from clumping or agglomerating, thus ensuring that the fertilizer is more dispersed when it leaves the blade, making its distribution more uniform.

[0041] Working principle: The rotation of the rotating shaft 1 drives the spreading mechanism 2 to rotate, causing the fertilizer to move in a circular motion on the spreading blades 24. This centrifugal force causes the fertilizer to move towards the edge of the spreading blades 24, providing the fertilizer with the propulsion for spreading. The spreading mechanism 2 is staggered along the rotating shaft 1, ensuring that the fertilizer is subjected to centrifugal force at different positions and angles, thus evenly spreading the fertilizer. The output end of the motor 31 and the support base 33 fix the two sides of the second rotating shaft 32, enabling the motor 31 to drive the second rotating shaft 32. Rotating shaft 32 rotates along its axis and is connected to bevel gear 34 via a keyway, causing bevel gear 34 to drive bevel gear 35 to rotate. Bevel gear 35 is then connected to rotating shaft 21 via a keyway, causing rotating shaft 21 to rotate. This causes connecting plate 23 to drive spreading blade 24 to rotate, thereby adjusting the angle of spreading blade 24. Power is transmitted through motor 31, allowing spreading blade 24 to quickly adjust its angle, thus enabling precise control of the fertilizer spreading direction.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
