Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1-4, the fertilizer metering device for controlling the feeding amount through the running speed of the conveyor belt comprises a rectangular blanking hopper 6 and a batching conveyor device; the batching and conveying device comprises two parallel brackets 1 and a closed conveying belt 4; two sides of the conveyor belt 4 are connected with baffle plates 5; the bottom end of the bracket 1 is provided with a supporting frame 7, the side wall of the bracket is provided with a variable frequency motor 3, and a plurality of conveying rollers 2 are rotatably arranged among the brackets 1 at equal intervals; the conveying belt 4 is arranged on the surface of the conveying roller 2, and the support frame 7 is provided with an ultrasonic velocimeter 13 through a support rod 14; the variable frequency motor 3 and the ultrasonic velocimeter 13 are both connected with the controller; the rectangular blanking funnel 6 is positioned at the feeding end of the conveyor belt 4, the upper end surface of the rectangular blanking funnel is fixed, and the lower end surface of the rectangular blanking funnel extends to the upper end surface of the conveyor belt 4; an arched opening 8 is arranged below the side wall of the rectangular blanking funnel 6 vertical to the running direction of the conveyor belt 4.

Above-mentioned fertilizer metering device, the batching is discharged from arch opening 8, and along with conveyer belt 4 motion, the batching is piled up and is the arch shape, compares in the rectangle, and the arch is difficult to loose. The transmission speed of the ingredients is measured through the ultrasonic velocimeter 13, the ingredient conveying capacity in unit time can be obtained according to the measured transmission speed, the addition amount of the ingredients can be measured, the proportion of each ingredient is accurately controlled, and the stability of the fertilizer quality is ensured. When the adding amount of the ingredients needs to be adjusted, the running speed of the conveying belt can be regulated and controlled by adjusting the speed of the variable frequency motor.

In particular, the device also comprises a mixed ingredient conveying belt 10, and the mixed ingredient conveying belt 10 is positioned right below the discharge end of the conveying belt 4.

In particular, in order to prevent the ingredients from being too loose, the arched opening 8 is connected with an arched shaping cylinder 9,

specifically, in order to enhance the shaping effect, the inner diameter of the arcuate shaping cylinder 9 is gradually reduced from the end connected to the arcuate opening 8 to the outlet end.

Specifically, the baffle 5 is bent in an "S" shape. When the conveyor belt 4 moves to the turning positions at the two ends in the operation process, the baffle 5 needs to be stretched, and the baffle 5 is designed into an S-shaped bent shape, so that the baffle 5 has more deformation, and the baffle is prevented from being broken.

Specifically, in order to further improve the toughness of the baffle 5 and prevent the baffle 5 from breaking, the baffle 5 is made of rubber.

Specifically, the ingredients are powdery, fly dust is inevitably generated at the moment of falling on the conveyor belt 4, in order to avoid the diffusion of the fly dust, a dust cover 11 is installed at one end of the bracket 1, and the dust cover 11 is positioned at the discharge end of the conveyor belt 4 and above the mixed ingredient conveyor belt 10; the dust cover 11 is opened at the side opposite to the rectangular blanking funnel 6 and the bottom, and the upper wall of the dust cover is higher than the upper edge of the arched shaping cylinder 9.

Specifically, a cloth bag 12 is installed at the bottom end of the dust cover 11, and the lower end of the cloth bag 12 is in lap joint with the upper end face of the mixed ingredient conveying belt 10.
