[0006] Each of the upper fertilizer spreading plate, the middle fertilizer spreading plate and the lower fertilizer spreading plate is divided into three temporary storage chambers by an L-shaped partition plate, and a curved baffle is arranged at the front end of each temporary storage chamber.

[0007] In an optional embodiment, the first fertilizer spreading assembly and the second fertilizer spreading assembly are both equipped with a fertilizer supply pipe, and each of the fertilizer supply pipes is sequentially provided with an upper layer discharge port, a middle layer discharge port and a lower layer discharge port from top to bottom.

[0008] In an optional embodiment, the upper layer discharge port, the middle layer discharge port and the lower layer discharge port are all connected to a strip-shaped feeding trough, the distal end of the strip-shaped feeding trough is arranged in an open shape, a plurality of evenly distributed diversion baffles are arranged in the strip-shaped feeding trough, and the plurality of diversion baffles are all located in the open structure of the strip-shaped feeding trough, an adjustment baffle is arranged on the side wall of the open structure, and the adjustment baffle is driven by a servo gear.

[0009] In an optional embodiment, the arc-shaped baffle at the front end of the temporary storage chamber is an upper arc-shaped baffle, a middle arc-shaped baffle and a lower arc-shaped baffle in sequence, and the upper arc-shaped baffle, the middle arc-shaped baffle and the lower arc-shaped baffle are increased in sequence.

[0010] In an optional embodiment, the sizes of the upper arc-shaped baffle plate, the middle arc-shaped baffle plate and the lower arc-shaped baffle plate can be adjusted along the edge of the arc-shaped distal end of the temporary storage cavity.

[0011] In an optional embodiment, the relative positions of the upper fertilizer spreading disc, the middle fertilizer spreading disc and the lower fertilizer spreading disc in the first fertilizer spreading assembly and the second fertilizer spreading assembly are not adjustable.

[0012] In an optional embodiment, the relative positions of the upper fertilizer spreading disc, the middle fertilizer spreading disc and the lower fertilizer spreading disc in the first fertilizer spreading assembly are not adjustable; the distances between the upper fertilizer spreading disc, the middle fertilizer spreading disc and the lower fertilizer spreading disc in the second fertilizer spreading assembly are adjustable, and the rotation speeds of the upper fertilizer spreading disc, the middle fertilizer spreading disc and the lower fertilizer spreading disc can be set separately.

[0013] On the other hand, the present invention also provides a method for using the multi-layer disc strip feeding and uniform fertilizer spreading device as described above, comprising:

[0014] The upper spreading disc, the middle spreading disc and the lower spreading disc in the first spreading assembly and the second spreading assembly are used for spreading fertilizer.

[0015] In an optional embodiment, the upper fertilizer spreading disc, the middle fertilizer spreading disc and the lower fertilizer spreading disc in the first fertilizer spreading assembly and the second fertilizer spreading assembly have the same vertical position and rotation speed, and the corresponding arc-shaped baffles have the same position and size; so that the fertilizer in each fertilizer spreading assembly is spread on the same arc.

[0016] In an optional embodiment, the upper and lower positions, rotation speeds, and arc-shaped baffle positions and sizes of the upper, middle, and lower fertilizer spreading plates in the second fertilizer spreading assembly are adjusted so that the upper, middle, and lower fertilizer spreading plates can spread fertilizer on the same arc or on different arcs.

[0017] The beneficial effects of the present invention are:

[0018] (1) The present invention adopts a multi-layer circular fertilizer spreading disk structure, which reduces the amount of fertilizer that needs to be spread by each circular fertilizer spreading disk, improves the controllability of the movement of fertilizer on each circular fertilizer spreading disk, and can effectively improve the uniformity of fertilizer spreading; at the same time, the diameters of the upper fertilizer spreading disk, the middle fertilizer spreading disk and the lower fertilizer spreading disk increase from top to bottom, so that the fertilizer landing point can be formed on the same arc by adjusting the rotation speed of the drive shaft and the feeding speed, thereby ensuring the accuracy of fertilizer spreading.

[0019] (2) The present invention can improve work efficiency by providing two identical first fertilizer spreading components and second fertilizer spreading components; by providing two different first fertilizer spreading components and second fertilizer spreading components, when the parameters of the second fertilizer spreading components are the same as those of the first fertilizer spreading components, the work efficiency can be improved. When the parameters of the second fertilizer spreading components are different from those of the first fertilizer spreading components, that is, adjusting the distances between the upper fertilizer spreading disc, the middle fertilizer spreading disc and the lower fertilizer spreading disc in the second fertilizer spreading component, and separately adjusting the rotation speed, feeding speed and number, size and position of the spreading openings of the upper fertilizer spreading disc, the middle fertilizer spreading disc and the lower fertilizer spreading disc, different fertilizer spreading requirements can be met at the same time, the fertilizer can be spread to the specified landing point at the same rate or different rates, and the landing point can be controlled on the same arc or on different arcs to meet various working conditions.

[0020] (3) A portion of the L-shaped partition plate on each spreading plate of the present invention is used for separation, and the other portion is used to prevent uneven fertilizer spreading caused by fertilizer flying out of the top of the temporary storage cavity or entering other temporary storage cavities due to inertia. A spreading port is formed between the arc-shaped baffle plate at the front end of the temporary storage cavity and the adjacent L-shaped partition plate. When spreading fertilizer, the fertilizer is spread out through each spreading port, which can better control the spreading direction of the fertilizer.

[0021] In particular, each arc baffle can be slidably connected to the corresponding fertilizer spreading plate, and each arc baffle can be set as a retractable arc plate. Each arc baffle can form one or two fertilizer spreading ports between two adjacent L-shaped partition plates, so that the number and size of each fertilizer spreading port can be adjusted, which can better control the discharging direction and discharging rate.

[0022] (4) The present invention adopts a strip feeding method and arranges a plurality of diversion baffles to evenly distribute the fertilizer on each fertilizer spreading disc. During the spreading process, the fertilizer can move in an orderly manner on each fertilizer spreading disc, which is beneficial to improving the uniformity of fertilizer spreading compared to the centralized feeding method where the fertilizer rushes out all at once. At the same time, the fertilizer spreading width can be adjusted by controlling the position of the baffle. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1

[0034] Please see attached Figure 1-5The purpose of this embodiment is to provide a multi-layer disc strip feeding uniform fertilizer spreading device, comprising: a frame 1, a first fertilizer spreading assembly and a second fertilizer spreading assembly are arranged on the frame 1, and the first fertilizer spreading assembly and the second fertilizer spreading assembly are sequentially provided with a circular upper fertilizer spreading disc 8, a middle fertilizer spreading disc 7 and a lower fertilizer spreading disc 6 from top to bottom; wherein the diameters of the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 increase in sequence. In this embodiment, the structures of the first fertilizer spreading assembly and the second fertilizer spreading assembly are exactly the same.

[0035] Specifically, each upper fertilizer spreading plate 8, middle fertilizer spreading plate 7 and lower fertilizer spreading plate 6 are divided into three temporary storage chambers by an L-shaped partition plate 20, and an arc-shaped baffle is provided at the front end of each temporary storage chamber. It should be noted that a part of the L-shaped partition plate 20 is used for separation, and the other part is used to prevent the fertilizer from flying out of the top of the temporary storage chamber or entering other temporary storage chambers due to inertia, causing uneven fertilizer spreading. The arc-shaped baffles at the front end of the temporary storage chamber are the upper arc-shaped baffle 17, the middle arc-shaped baffle 18 and the lower arc-shaped baffle 19 in sequence, and the upper arc-shaped baffle 17, the middle arc-shaped baffle 18 and the lower arc-shaped baffle 19 are enlarged in sequence, and one side of the upper arc-shaped baffle 17, the middle arc-shaped baffle 18 and the lower arc-shaped baffle 19 is attached to an adjacent L-shaped partition plate 20, and a spreading port is formed between the other adjacent L-shaped partition plate 20, and each arc-shaped baffle is of a fixed size, and each spreading port is of a fixed size, and the spreading ports on the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6 are enlarged in sequence. When spreading fertilizer, the fertilizer is sprinkled through each spreading port, and the spreading direction of the fertilizer can be better controlled.

[0036] Furthermore, the first fertilizer spreading assembly and the second fertilizer spreading assembly are both equipped with a fertilizer supply pipe 9, and each fertilizer supply pipe 9 is sequentially provided with an upper layer discharge port 13, a middle layer discharge port 12, and a lower layer discharge port 11 from top to bottom. The upper layer discharge port 13, the middle layer discharge port 12, and the lower layer discharge port 11 are all connected to a strip feeding trough 10, the strip feeding trough 10 is designed to be inclined, and the far end of the strip feeding trough 10 is set in an open shape. A plurality of evenly distributed diverter baffles 14 are arranged in the strip feeding trough 10, and the plurality of diverter baffles 14 are all located in the open structure of the strip feeding trough 10, and an adjustment baffle 15 is arranged on the side wall of the open structure, and the adjustment baffle 15 is driven by a steering gear 16. By setting a plurality of diversion baffles 14, the fertilizer is evenly distributed on each fertilizer spreading disc. During the spreading process, the fertilizer can move in an orderly manner on each fertilizer spreading disc, which is beneficial to improving the uniformity of fertilizer spreading compared with the rush of concentrated feeding. At the same time, by controlling the position of the baffle 15, the fertilizer spreading width can be adjusted.

[0037] In this embodiment, the relative positions of the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 in the first fertilizer spreading assembly and the second fertilizer spreading assembly are not adjustable. The upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 are all fixedly arranged on the drive shaft 4, each drive shaft 4 is driven by a drive motor, the drive motor is connected to the drive shaft 4 through a right angle commutator 3, and the drive shaft 4 is connected to the frame 1 through a seat bearing 5.

[0038] Use the spreading device by following the steps below:

[0039] S1: starting the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 in the first fertilizer spreading assembly and the second fertilizer spreading assembly, and the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 rotate synchronously with the driving shaft 4 at the same speed;

[0040] S2: Start the fertilizer supply pipe 9, and the fertilizer enters the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7, the lower fertilizer spreading plate 6, and the upper fertilizer spreading plate 8 through the upper discharge port 13, the middle discharge port 12, the lower discharge port 11 and the strip feeding trough 10;

[0041] S3: Open the regulating baffle 15 at a uniform speed to the designated diverter baffle 14 or fully open it (to adjust the feeding speed);

[0042] S4: adjusting the rotation speed and / or feeding speed of the driving shaft 4 so that the landing points of the fertilizer spread out through the spreading openings of the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6 are located on the same arc.

[0043] The structure of multi-layer circular fertilizer spreading discs is adopted, which reduces the amount of fertilizer that needs to be spread by each circular fertilizer spreading disc, improves the controllability of the movement of fertilizer on each circular fertilizer spreading disc, and can effectively improve the uniformity of fertilizer spreading; at the same time, the diameters of the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 increase from top to bottom, so that the fertilizer landing point can be formed on the same arc by adjusting the rotation speed of the drive shaft 4 and the feeding speed, thereby ensuring the accuracy of fertilizer spreading.

[0044] Embodiment 2

[0045] Please see attached Figure 1-5 The purpose of this embodiment is to provide a multi-layer disc strip feeding uniform fertilizer spreading device, comprising: a frame 1, a first fertilizer spreading assembly and a second fertilizer spreading assembly are arranged on the frame 1, and the first fertilizer spreading assembly and the second fertilizer spreading assembly are sequentially provided with a circular upper fertilizer spreading disc 8, a middle fertilizer spreading disc 7 and a lower fertilizer spreading disc 6 from top to bottom; wherein the diameters of the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 increase in sequence. In this embodiment, the structures of the first fertilizer spreading assembly and the second fertilizer spreading assembly are different.

[0046] Specifically, each upper fertilizer spreading plate 8, middle fertilizer spreading plate 7 and lower fertilizer spreading plate 6 in the first fertilizer spreading assembly and the second fertilizer spreading assembly are divided into three temporary storage chambers by an L-shaped partition plate 20, and an arc-shaped baffle is provided at the front end of each temporary storage chamber. It should be noted that a part of the L-shaped partition plate 20 is used for separation, and the other part is used to prevent fertilizer from flying out of the top of the temporary storage chamber or entering other temporary storage chambers due to inertia, causing uneven fertilizer spreading. The arc-shaped baffles at the front ends of the temporary storage chambers of the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6 are an upper arc-shaped baffle 17, a middle arc-shaped baffle 18 and a lower arc-shaped baffle 19, respectively, and the upper arc-shaped baffle 17, the middle arc-shaped baffle 18 and the lower arc-shaped baffle 19 are increased in size in sequence.

[0047] In the first fertilizer spreading assembly, one side of the upper arc baffle 17, the middle arc baffle 18 and the lower arc baffle 19 is attached to an adjacent L-shaped partition 20, and a spreading opening is formed between the upper arc baffle and the other adjacent L-shaped partition 20. The size of each arc baffle is fixed, and the size of each spreading opening is fixed. The spreading openings on the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6 are successively larger. When spreading fertilizer, the fertilizer is spread out through each spreading opening, and the spreading direction of the fertilizer can be better controlled.

[0048] In the second fertilizer spreading assembly, the sizes of the upper arc baffle 17, the middle arc baffle 18 and the lower arc baffle 19 can be adjusted along the edge of the arc distal end of the temporary storage chamber, and are slidably connected to the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6 respectively. Specifically, the upper arc baffle 17, the middle arc baffle 18 and the lower arc baffle 19 are all retractable arc plates. It can be seen that the fertilizer spreading port formed between the upper arc baffle 17, the middle arc baffle 18 and the lower arc baffle 19 and the two adjacent L-shaped partition plates 20 can be one or two. Regardless of whether the fertilizer spreading port is one or two, since the size of each arc plate is adjustable, the size of each fertilizer spreading port is adjustable, and the discharging direction and discharging rate can be better controlled.

[0049] Furthermore, the first fertilizer spreading assembly and the second fertilizer spreading assembly are both equipped with a fertilizer supply pipe 9, and each fertilizer supply pipe 9 is sequentially provided with an upper layer discharge port 13, a middle layer discharge port 12, and a lower layer discharge port 11 from top to bottom. The upper layer discharge port 13, the middle layer discharge port 12, and the lower layer discharge port 11 are all connected to a strip feeding trough 10, the strip feeding trough 10 is designed to be inclined, and the far end of the strip feeding trough 10 is set in an open shape. A plurality of evenly distributed diverter baffles 14 are arranged in the strip feeding trough 10, and the plurality of diverter baffles 14 are all located in the open structure of the strip feeding trough 10, and an adjustment baffle 15 is arranged on the side wall of the open structure, and the adjustment baffle 15 is driven by a steering gear 16. By setting a plurality of diversion baffles 14, the fertilizer is evenly distributed on each fertilizer spreading disc. During the spreading process, the fertilizer can move in an orderly manner on each fertilizer spreading disc, which is beneficial to improving the uniformity of fertilizer spreading compared with the rush of concentrated feeding. At the same time, by controlling the position of the baffle 15, the fertilizer spreading width can be adjusted.

[0050] In this embodiment, the relative positions of the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 in the first fertilizer spreading assembly are not adjustable. The upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 are all fixedly arranged on the drive shaft 4, each drive shaft 4 is driven by a drive motor, the drive motor is connected to the drive shaft 4 through a right angle commutator 3, and the drive shaft 4 is connected to the frame 1 through a seat bearing 5.

[0051] In the second fertilizer spreading assembly, the distances between the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 are adjustable, and the rotation speeds of the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 can be set individually. Thus, each fertilizer spreading disc can control the feeding speed, rotation speed, fertilizer spreading rate and landing point individually, so that the practical performance of the fertilizer spreading device is effectively improved.

[0052] Use the spreading device by following the steps below:

[0053] S1: starting the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 in the first fertilizer spreading assembly, and the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 rotate synchronously with the driving shaft 4 at the same speed;

[0054] S2: Start the fertilizer supply pipe 9, and the fertilizer enters the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7, the lower fertilizer spreading plate 6, and the upper fertilizer spreading plate 8 through the upper discharge port 13, the middle discharge port 12, the lower discharge port 11 and the strip feeding trough 10;

[0055] S3: Open the regulating baffle 15 at a uniform speed to the designated diverter baffle 14 or fully open it (to adjust the feeding speed);

[0056] S4: adjusting the rotation speed and / or feeding speed of the driving shaft 4 so that the landing points of the fertilizer spread out through the spreading openings of the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6 are located on the same arc to ensure the accuracy of fertilizer spreading.

[0057] The first fertilizer spreading component adopts a multi-layer circular fertilizer spreading disc structure, which reduces the amount of fertilizer that needs to be spread on each circular fertilizer spreading disc, improves the controllability of the movement of fertilizer on each circular fertilizer spreading disc, and can effectively improve the uniformity of fertilizer spreading; at the same time, the diameters of the upper fertilizer spreading disc 8, the middle fertilizer spreading disc 7 and the lower fertilizer spreading disc 6 increase from top to bottom, so that the fertilizer landing point can be formed on the same arc by adjusting the rotation speed of the drive shaft 4 and the feeding speed.

[0058] S5: The second fertilizing assembly is configured exactly the same as the first fertilizing assembly, including the relative positions of the upper fertilizing plate 8, the middle fertilizing plate 7 and the lower fertilizing plate 6, the feeding speed and the size and position of each fertilizing opening. The second fertilizing assembly works synchronously with the first fertilizing assembly to improve the work efficiency of completing the same fertilizing target;

[0059] S6: Adjust the distances between the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6 in the second fertilizer spreading assembly, and individually adjust the rotation speed, feeding speed and the number, size and position of the spreading ports of the upper fertilizer spreading plate 8, the middle fertilizer spreading plate 7 and the lower fertilizer spreading plate 6, so as to meet different fertilizer spreading needs at the same time, spread the fertilizer to the designated landing point at the same rate or different rates, and control the landing point on the same arc or on different arcs.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
