Description

Technical Field

[0001] The utility model belongs to the technical field of mixing devices, and particularly relates to a mixing device for agricultural planting and fertilization. Background Art

[0002] In the current agricultural production process, the application of fertilizers is crucial to the growth of crops. However, due to differences in soil characteristics and crop needs, a single fertilizer often cannot meet actual needs. Therefore, it is usually necessary to mix multiple raw fertilizers for use. However, the mixing devices currently on the market have significant deficiencies in the mixing process. Traditional mixing devices mostly use two mixing methods: one is to add raw fertilizers in batches, that is, add one raw fertilizer first, and then add the next one after it is mixed evenly. This method is not only cumbersome and inefficient, but also increases labor costs; the other is to add all the raw fertilizers first and then mix them. However, due to differences in physical properties such as density and particle size of the raw fertilizers, different addition orders often cause the raw fertilizers to stratify during the mixing process, thereby affecting the uniformity of the mixing and, in turn, affecting the fertilization effect. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a novel fertilization mixing device capable of simultaneously inputting a variety of raw fertilizers and mixing them, so as to solve the above-mentioned problems.

[0004] The utility model discloses a mixing device for agricultural planting and fertilization, comprising a mixing tank, wherein a stirring shaft is arranged in the mixing tank, and a plurality of raw material tanks in an array rotating around the stirring shaft are arranged on the top of the mixing tank, and a matching first conveying screw is arranged in each raw material tank, and a driving mechanism for driving the stirring shaft to rotate is arranged on the top of the mixing tank, a first transmission part is arranged between the stirring shaft and one of the first conveying screws, and a second transmission part is arranged between all the first conveying screws, and the bottom of the mixing tank is funnel-shaped and is provided with a mixing output pipe, and the mixing output pipe is provided with a valve.

[0005] Furthermore, the driving mechanism is a bidirectional reduction motor, a one-way clutch is provided at the bottom end of the stirring shaft, a second conveying screw adapted to the mixing output pipe is provided on the one-way clutch, the rotation direction of the second conveying screw is opposite to that of the first conveying screw, each of the first conveying screws is provided with a one-way clutch gear cooperating with the first transmission part, and the one-way clutch gear is opposite to the limiting direction of the one-way clutch.

[0006] Furthermore, the first transmission part is a synchronous belt, and the synchronous belt is sleeved on all the one-way clutch gears.

[0007] Furthermore, a bearing frame matched with the second conveying screw is arranged in the mixing tank.

[0008] Furthermore, a C-shaped bracket for mounting a driving mechanism is provided on the top of the mixing tank.

[0009] Furthermore, a plurality of cross bars are arranged on the stirring shaft in an axially rotating array, the cross bars are arranged in a plurality of layers of different lengths, and a stirring shovel is spirally arranged at the end of each cross bar, and the stirring shovels on two adjacent layers of cross bars are arranged with opposite rotation directions.

[0010] Compared with the existing technology, the mixing device significantly improves the mixing efficiency. By inputting multiple raw fertilizers at the same time and mixing them evenly, it reduces the operation steps and time and reduces the labor cost. At the same time, its optimized mixing structure and mixing method effectively avoid the stratification of raw fertilizers, ensure the uniformity of mixing, thereby improving the fertilization effect and providing a more efficient and economical fertilization solution for agricultural production.

[0018] The preferred technical solution in this embodiment is that in the mixing device, this embodiment preferably uses a bidirectional reduction motor as the driving mechanism 5, which can accurately control the forward and reverse rotation and speed of the stirring shaft 2, and realize flexible switching between mixing and discharging. A one-way clutch 10 is provided at the bottom end of the stirring shaft 2, wherein the outer diameter of the one-way clutch 10 is connected to the bottom end of the stirring shaft 2, and the inner diameter of the one-way clutch 10 is penetrated with a second conveying screw 11 adapted to the mixing output pipe 8, and the rotation direction of the second conveying screw 11 is opposite to that of the first conveying screw 4. Each first conveying screw 4 is provided with a one-way clutch gear 12 that cooperates with the first transmission part 6, and these one-way clutch gears 12 are opposite to the limiting direction of the one-way clutch 10. When the stirring shaft 2 rotates forward, the one-way clutch 10 is unlocked and the one-way clutch gear 12 is locked; when the stirring shaft 2 rotates reversely, the one-way clutch 10 is locked and the one-way clutch gear 12 is unlocked.

[0019] In the preferred technical solution of this embodiment, the first transmission part 6 is a synchronous belt, which is sleeved on all the one-way clutch gears 12. Through the transmission of the synchronous belt, all the first conveying screws 4 rotate synchronously. The second transmission part 7 also adopts a synchronous belt or other suitable transmission method to ensure that the speed and rotation direction of all the first conveying screws 4 are consistent.

[0020] In the preferred technical solution of this embodiment, a plurality of crossbars 15 are arranged in an axially rotating array on the stirring shaft 2, and the crossbars 15 are arranged in a plurality of layers of different lengths to increase the stirring range. A stirring shovel 16 is spirally arranged at the end of each crossbar 15, and the stirring shovels 16 on two adjacent layers of crossbars 15 are arranged in opposite directions to increase the stirring effect. When the stirring shaft 2 rotates, the stirring shovel 16 turns and mixes the raw fertilizer in the mixing tank 1.

[0023] The use and principle of the utility model: In the mixing state, the driving mechanism 5 is started to drive the stirring shaft 2 to rotate forward. At this time, the one-way clutch 10 is in an unlocked state, the second conveying screw 11 does not rotate, and the valve 9 is closed. At the same time, the one-way clutch gear 12 is in a locked state, and through the transmission of the first transmission part 6, all the first conveying screws 4 are driven to rotate forward synchronously to transport the raw fertilizer in the raw material tank 3 into the mixing tank 1. The stirring shovel 16 on the stirring shaft 2 turns and mixes the raw fertilizer during the rotation process to ensure the uniformity of the mixing.

[0024] In the discharging state, the driving mechanism 5 causes the stirring shaft 2 to rotate in the reverse direction. At this time, the one-way clutch gear 12 is in an unlocked state, the first conveying screw 4 loses power, and stops conveying the raw materials. The one-way clutch 10 is in a locked state, driving the second conveying screw 11 to rotate in the reverse direction synchronously. At the same time, the valve 9 is opened, and the mixed fertilizer is pushed to the bottom of the mixing tank 1 under the centrifugal force of the reverse rotation of the stirring shaft 2, and is discharged from the mixing output pipe 8 through the action of the second conveying screw 11.
