Description

Technical Field

[0001] This utility model relates to the field of blended fertilizer metering technology, specifically a metering device for blended fertilizer production. Background Technology

[0002] Blended fertilizer is a type of fertilizer produced through a simple mechanical mixing method. It is mainly composed of two or more single-element fertilizers or compound fertilizers mixed in a certain proportion, and therefore requires measurement during the production of blended fertilizer.

[0003] For example, a batching scale for precise metering in blended fertilizer production, authorized by publication number "CN216954788U," can stir the materials inside the material tank, effectively improving the accuracy and efficiency of precise metering in blended fertilizer production. However, after metering the blended fertilizer, workers need to frequently move the receiving trough away from the electronic scale, increasing their workload. Furthermore, when replenishing the blended fertilizer in the material tank, the excessively high inlet at the top of the material pipe makes it inconvenient for workers to open, thus reducing its practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems that after the blended fertilizer is metered, workers need to frequently move the receiving trough away from the electronic scale, which increases the workload of workers, and that the feeding port above the material pipe is too high, making it inconvenient for workers to open the feeding port above the material pipe, thus reducing its practicality. Therefore, a metering device for blended fertilizer production is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a metering device for blended fertilizer production, including a box and a frame. The outer wall of the box is fixedly connected to the frame. The right end of the box is fixedly connected to a plate. A moving mechanism is installed on the left end of the frame. An opening and closing mechanism is installed on the upper end of the plate. The inner wall of the box is rotatably connected to the cover. The lower end of the box is provided with a discharge port. A solenoid valve is provided on the inner wall of the discharge port.

[0007] Preferably, the moving mechanism includes a first housing, the right end of which is fixedly connected to the frame, the inner wall of which is fixedly connected to a first motor via a bracket, the output shaft of which is connected to the rotating shaft of the roller via a reduction gearbox, and the outer walls of the roller on both sides are rotatably connected to the first housing and the frame via rotating shafts respectively.

[0008] Preferably, the roller is slidably connected to the horizontal plate via an arc groove, the inner wall of the horizontal plate is slidably connected to the horizontal bar, the left end of the horizontal bar is fixedly connected to the first housing, and the right outer wall of the horizontal bar is slidably connected to the frame.

[0009] Preferably, the opening and closing mechanism includes a second housing, the lower end of which is fixedly connected to the plate, the inner wall of which is fixedly connected to a second motor via a bracket, the output shaft of which is connected to the rotating shaft of the column via a reduction gearbox, the inner wall of which is rotatably connected to the second housing via the rotating shaft, and a rope is wound around the outer wall of the middle part of the column.

[0010] Preferably, the left end of the rope is fixedly connected to the support rod, both ends of the support rod are fixedly connected to the vertical plate, and the lower end of the vertical plate is fixedly connected to the cover.

[0011] Preferably, the inner wall of the frame is fixedly connected to the electronic scale, the upper end of the electronic scale is attached to the recycling bin, and the right end of the frame is adjacent to the conveyor belt.

[0012] The metering device for blended fertilizer production proposed in this utility model has the following advantages: Through the cooperation of the moving mechanism and the frame, the first motor drives the drum to rotate, and the drum drives the horizontal plate to move to the right through the arc groove. The horizontal plate contacts the recycling box and pushes the recycling box to move in the direction of the conveyor belt. After the recycling box is pushed onto the conveyor belt, the drum has already driven the horizontal plate to move to the right to the limit position. The first motor continues to rotate, and the arc groove of the drum drives the horizontal plate to move to the left. After the horizontal plate moves to the left to the reset position, the first motor is turned off. In this way, workers do not need to frequently move the recycling box, thereby reducing the workload of workers.

[0013] Through the cooperation of the opening and closing mechanism and the plate, the second motor drives the column to rotate. The rotation of the column causes the rope to wind up. The winding rope drives the support rod to move to the right. The support rod drives the vertical plate to move. The vertical plate drives the cover to rotate clockwise, thereby opening the notch on the top of the box. After the cover rotates to open the notch on the top of the box, the second motor is turned off. In this way, the opening or closing of the top of the box can be directly controlled, which makes it easier to add blended fertilizer into the box, thereby increasing its practicality.

[0025] Working principle:

[0026] When it is necessary to measure the blended fertilizer (the blended fertilizer is pre-stored in the box 1), first place the recycling box 6 on the electronic scale 5, then press the tare button on the electronic scale 5 to take the weight of the recycling box 6. Then, open the discharge port 9 through the solenoid valve, and the blended fertilizer in the box 1 falls into the recycling box 6 through the discharge port 9. As more and more blended fertilizer is added to the recycling box 6, the weight of the recycling box 6 will become heavier and heavier. The electronic scale 5 weighs the recycling box 6 and displays the weight on the display screen of the electronic scale 5 (the electronic scale 5 is existing technology, and the above weighing method of the electronic scale 5 can be implemented in existing technology). The blended fertilizer is accurately measured in the above way. When the weight of the blended fertilizer in the recycling box 6 reaches the required level, the discharge port 9 is closed through the solenoid valve.

[0027] Then, the external power supply of the first motor 202 is connected and started. The first motor 202 drives the roller 203 to rotate. The roller 203 drives the horizontal plate 204 to move to the right through the arc groove. The horizontal plate 204 contacts the recycling box 6 and pushes the recycling box 6 towards the conveyor belt 7. After the recycling box 6 is pushed onto the conveyor belt 7, the roller 203 has moved the horizontal plate 204 to the right to its limit position. The first motor 202 continues to rotate, and the arc groove of the roller 203 drives the horizontal plate 204 to move to the left (the arc groove on the front side of the roller 203 is connected to the arc groove on the rear side, so the horizontal plate 204 will not get stuck when moving). Figure 3 and Figure 4 (As shown in roller 203), after the horizontal plate 204 moves to the left to reset, the first motor 202 is turned off. In the above manner, the horizontal plate 204 pushes the recycling box 6 onto the conveyor belt 7, so that the workers do not need to frequently move the recycling box 6. Then, the external power supply of the conveyor belt 7 is connected and started. The conveyor belt 7 transports the recycling box 6 to the next process. Then, the workers place the new recycling box 6 on the electronic scale 5, and then measure the blended fertilizer in the above manner.

[0028] When it is necessary to replenish the blended fertilizer in box 1, connect the external power supply of the second motor 302 and start it. The second motor 302 drives the column 303 to rotate. The rotation of the column 303 causes the rope 304 to wind up. The winding rope 304 drives the support rod 306 to move to the right. The support rod 306 drives the vertical plate 305 to move. The vertical plate 305 drives the cover 8 to rotate clockwise, thereby opening the gap at the top of box 1. After the cover 8 rotates 70 degrees and opens the gap at the top of box 1, turn off the second motor 302 (the maximum angle of rotation of the cover 8 is 80 degrees). Then, use external conveying equipment to transport the blended fertilizer into box 1 to replenish the blended fertilizer in box 1. After the blended fertilizer in box 1 is replenished, remove the external conveying equipment. Then, reverse the second motor 302 in the above manner to turn the cover 8 in the opposite direction and close the gap at the top of box 1. After the gap at the top of box 1 is closed, turn off the second motor 302. The replenishment of blended fertilizer in box 1 is completed in the above manner.
