Fertilization amount control device

Abstract

The utility model discloses a fertilizing amount control device, and relates to a fertilizing amount control device used on a fertilizing machine in agriculture. The problems that in the prior art, real-time control over any flow cannot be achieved, and fertilizer loss is likely to be caused are solved. The device comprises a first auger body, a first conveying round pipe, a power transmission chain, a motor and a speed regulation control power supply, a fertilizer inlet hole is formed in the upper part of one end of the first conveying round pipe, and a fertilizer outlet hole is formed in the lower part of the other end of the first conveying round pipe; the other end of the transmission chain is connected with a motor which is connected with a speed regulation control power supply. During working, fertilizer particles are filled in the screw pitch grooves of the auger body. Under the driving of the motor, fertilizer particles are pushed to the other end from the fertilizer inlet hole end and flow out from the fertilizer outlet hole end. As the speed regulation control power supply can control any voltage output in real time, the rotating speed of the auger body can be randomly adjusted in real time, and the fertilizer amount can be controlled in real time. The closed first conveying round pipe ensures that the fertilizer cannot be spilled out, and loss is avoided.

Description

Technical Field

[0001] The utility model relates to a fertilizer application amount control device used on a fertilizer applicator in agriculture. Background Art

[0002] With the popularization of rural agricultural mechanization, in order to increase the fertility of the land, fertilizer spreaders are generally used to fertilize the soil after the land is organized. The existing fertilizer spreaders rely on the power output of vehicles (such as tractors) to drive the fertilizer throwing disk through the transmission shaft to realize the automatic fertilizer spreading operation. For example, the patent "A Fertilizer Mixing and Fertilizer Spreading Machine" with the authorization announcement number CN201620839704.2.

[0003] Automated equipment of course requires precise control. Regarding the amount of fertilizer applied, if the amount of fertilizer applied by the fertilizer applicator cannot be accurately controlled, the fertilized land will not be able to achieve ideal planting conditions.

[0004] The bagged fertilizers currently sold by manufacturers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers or compound fertilizers, are generally in the shape of granular solids with a diameter of 2-3 mm. They can flow under the action of external force, which provides the basic conditions for accurately controlling the amount of fertilizer applied.

[0005] The "A Fertilizer Mixing and Spreading Machine" with the authorization announcement number CN201620839704.2 discloses a fertilizer quantity control disk, the disk body of which is provided with a first through hole, the lower surface of which is in contact with the upper surface of the bottom pocket, and the disk body of the bottom pocket is provided with a second through hole. When the first through hole is directly opposite to the second through hole, the fertilizer passes through; and when the first through hole is staggered with the second through hole, the fertilizer is prohibited from passing through. The amount of fertilizer is controlled by utilizing this opening and closing relationship. This method of controlling the amount of fertilizer has the following problems: 1. The fertilizer is exposed and does not form a closed space, so it is easy to spill out and cause losses. 2. The rotating fertilizer quantity control disk does not have an independent driving power source, and the amount of fertilizer cannot be controlled in real time at any flow rate. Utility Model Content

[0006] The utility model aims to provide a fertilizer application amount control device to solve the problems that the prior art cannot achieve real-time arbitrary flow control and easily causes fertilizer loss.

[0007] It comprises a No. 1 auger body 1, a No. 1 transmission tube 2, a power transmission chain 4, a motor 5, and a speed control power supply 6; both ends of the No. 1 transmission tube 2 are closed, a fertilizer inlet hole 2-1 is opened on the cylindrical surface of the upper part of one end of the No. 1 transmission tube 2, and a fertilizer outlet hole 2-2 is opened on the cylindrical surface of the lower part of the other end of the No. 1 transmission tube 2; the No. 1 auger body 1 is arranged in the inner cylinder of the No. 1 transmission tube 2 along the length direction thereof, one end of the transmission chain 4 penetrates into the end of the No. 1 transmission tube 2 and is connected with a rotating shaft at one end of the No. 1 auger body 1; the other end of the transmission chain 4 is connected to the power output shaft of the motor 5, and the power input end of the motor 5 is connected to the power output end of the speed control power supply 6.

[0008] Preferably, the difference between the diameter d of the first auger body 1 and the inner diameter D of the first conveying circular tube 2 is smaller than the diameter of the fertilizer particles.

[0009] Preferably, the transmission chain 4 is a gear transmission structure.

[0010] Preferably, the gear transmission structure of the transmission chain 4 is a plastic or nylon gear transmission pair.

[0011] When the utility model is working, the fertilizer particles enter the No. 1 conveying circular tube 2 from the fertilizer inlet hole 2-1, fall into and continuously fill the pitch groove of the guide blade of the No. 1 auger body 1. Driven by the motor 5, the No. 1 auger body 1 rotates, pushing the fertilizer particles from the fertilizer inlet hole 2-1 end to the other end, and finally flowing out from the fertilizer outlet hole 2-2 end. Since the speed control power supply 6 can achieve real-time control of any voltage output, the rotation speed of the No. 1 auger body 1 can also be adjusted in real time, so the output fertilizer amount can also be controlled in real time at any flow rate. The closed No. 1 conveying circular tube 2 ensures that the fertilizer will not spill out, so there is no loss. The utility model has the advantages of simple structure and reliable operation.
