Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically to a compound fertilizer batching and weighing device. Background Technology

[0002] Compound fertilizer refers to fertilizer containing two or more major nutrients (nitrogen, phosphorus, and potassium). It is a commonly used high-efficiency fertilizer in agricultural production, which can simultaneously provide multiple nutrients needed for plant growth, promoting healthy plant growth and high yield.

[0003] A search revealed a precision weighing device for compound fertilizer production, application number CN201820668878.6. In this device, when using a weighing sensor to weigh the compound fertilizer ingredients, the feed pipe is closed by moving a baffle after the weight reaches a set value. However, because the baffle movement takes a certain amount of time, the compound fertilizer ingredients continue to enter the weighing chamber during the baffle closure process, causing the weight of the material in the weighing chamber to exceed the set value, making it inconvenient to accurately weigh the compound fertilizer ingredients.

Detailed Implementation

[0024] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0025] A compound fertilizer ingredient weighing device according to this specific embodiment, such as Figures 1-5 As shown, the system includes a base plate 1, a weighing box 2 located on the right side above the base plate 1, weighing sensors 3 fixed at the four corners of the bottom of the weighing box 2, and the bottom of the weighing sensors 3 bolted to the surface of the base plate 1. A first discharge pipe 4 is connected to the front and rear sides of the right side of the weighing box 2. A support frame 5 is fixed to the right side of the base plate 1, and a control panel 6 is installed on the front side of the support frame 5. A feeding module 7 is fixed above the support frame 5. A fixing shell 8 is fixed to the left side of the top of the base plate 1, and an adjustment module 9 is movably connected inside the fixing shell 8. A collection box 10 is fixed above the adjustment module 9, and a material extraction module 11 is located above the collection box 10. A second discharge pipe 12 is connected to the lower left side of the collection box 10.

[0026] The feeding module 7 includes a compound fertilizer feeding hopper 71, a feeding pipe 72, and a solenoid valve 73. The compound fertilizer feeding hopper 71 is fixed to the top of the support frame 5. The feeding pipe 72 is connected to the bottom of the compound fertilizer feeding hopper 71, and the bottom end of the feeding pipe 72 passes through the support frame 5 and extends to the top of the weighing box 2. The solenoid valve 73 is fixed above the surface of the feeding pipe 72. When the solenoid valve 73 is opened, the compound fertilizer in the compound fertilizer feeding hopper 71 will enter the feeding pipe 72 below. The compound fertilizer is fed into the weighing box 2 below through the feeding pipe 72 so that the weighing sensor 3 can weigh the compound fertilizer in the weighing box 2.

[0027] The adjustment module 9 includes a lead screw 91, a motor 92, and a moving platform 93. The lead screw 91 is rotatably connected inside the fixed housing 8. The motor 92 is fixed on the left side of the fixed housing 8. The moving platform 93 is slidably connected inside the left side of the fixed housing 8, and the lead screw 91 passes through the moving platform 93 and is threadedly connected to the moving platform 93. The bottom of the collection box 10 is fixedly connected to the top of the moving platform 93. Guide rails 13 are fixed on both the front and rear sides of the top of the fixed housing 8. Guide blocks 14 are fixed on both the front and rear sides of the bottom of the moving platform 93, and the guide blocks 14 are slidably connected to the guide rails 13. When the motor 92 is turned on, the output shaft of the motor 92 will drive the lead screw 91 to rotate, thereby causing the moving platform 93 to move on the surface of the lead screw 91. The guide rails 13 and guide blocks 14 are used to guide the moving platform 93 and increase the stability of the moving platform 93 when moving left and right. The moving platform 93 drives the collection box 10 above to move so that the collection box 10 is close to the weighing box 2 on one side, so as to extract excess compound fertilizer material inside the weighing box 2.

[0028] The material extraction module 11 includes a material extraction pump 111, a material extraction pipe 112, and a material passage pipe 113. The material extraction pump 111 is fixed to the top of the collection box 10. The material extraction pipe 112 is connected to the right side of the material extraction pump 111, and the material passage pipe 113 is connected to the rear side of the top of the collection box 10. The end of the material passage pipe 113 away from the collection box 10 is connected to the material extraction pump 111. The material extraction pipe 112 is L-shaped and is a retractable flexible hose. When the collection box 10 approaches the weighing box 2, the material extraction pipe 112 enters the interior of the weighing box 2 and comes into contact with the compound fertilizer. By turning on the material extraction pump 111, the material extraction pipe 112 draws the excess compound fertilizer from the weighing box 2 into the interior of the material passage pipe 113 and discharges it into the interior of the collection box 10, thus removing the excess compound fertilizer.

[0029] Electric telescopic rods 15 are fixed to the front and back of the top right side of the collection box 10, and a connecting rod 16 is fixed to the top of the output shaft of the electric telescopic rod 15. The end of the connecting rod 16 away from the output shaft of the electric telescopic rod 15 is fixedly connected to the surface of the extraction pipe 112. When the electric telescopic rod 15 is opened, the output shaft of the electric telescopic rod 15 extends and retracts, thereby stretching or contracting the second discharge pipe 12 so that the second discharge pipe 12 can extract the compound fertilizer ingredients inside the weighing box 2.

[0030] Its working principle is as follows:

[0031] When staff need to weigh the compound fertilizer ingredients, they first open the solenoid valve 73, causing the feeding pipe 72 to discharge the compound fertilizer ingredients from the feeding hopper 71 into the weighing box 2 below. At this time, the weighing sensor 3 below begins to weigh the compound fertilizer ingredients inside the weighing box 2. When the weight of the compound fertilizer ingredients inside the weighing box 2 reaches the required level, the staff closes the solenoid valve 73, and the remaining compound fertilizer ingredients in the feeding pipe 72 fall into the weighing box 2 below. The weighing sensor 3 detects the weight of the compound fertilizer ingredients inside the weighing box 2 and calculates the excess weight of the compound fertilizer ingredients. Then, the motor 92 on the left side is turned on, causing the collection box 10 to move to the right. The extraction pipe 112 is moved above the weighing box 2. At this time, the electric telescopic rod 15 is opened, and the bottom of the second discharge pipe 12 is lowered through the connecting rod 16. After the second discharge pipe 12 comes into contact with the compound fertilizer mixture inside the weighing box 2, the extraction pump 111 on one side will be opened. The extraction pump 111 accurately draws the excess compound fertilizer mixture inside the weighing box 2 into the collection box 10, thereby accurately weighing the compound fertilizer mixture. Then, the electric telescopic rod 15 controls the second discharge pipe 12 to rise again, and the collection box 10 is moved to the left through the motor 92. Then, the staff can open the first discharge pipe 4 on the right side of the weighing box 2 to take out the weighed compound fertilizer mixture, thus completing the weighing operation of the compound fertilizer mixture.
