Description

Technical Field

[0001] This utility model relates to the technical field of compound fertilizer weighing equipment, and in particular to a quantitative weighing device for discharging polypeptide chelated potassium compound fertilizer. Background Technology

[0002] Potassium chelate is an organic macromolecule invented based on crop root exudates. Its quantity and molecular weight are much larger than those of root exudates, thus helping crops "digest" nutrients and promoting their absorption and utilization. Potassium chelate compound fertilizer is a nutrient absorption promoter. The organic macromolecule reduces ammonia volatilization and improves nitrogen fertilizer utilization. Through the organic combination of potassium chelate and ammonium ions, the ammonium ions are firmly locked and adsorbed in the soil, preventing the conversion of ammonium ions into ammonia, thereby reducing nitrogen fertilizer loss and increasing nitrogen fertilizer utilization by more than double. Potassium chelate compound fertilizer evenly incorporates potassium chelate, chelated zinc, and organic boron into the compound fertilizer granules. 30 kg of this fertilizer has a higher fertilizer effect than 50 kg of ordinary compound fertilizer. After use, crops grow faster, while simultaneously supplementing chelated zinc and organic boron, resulting in higher yields and earlier maturity.

[0003] Currently, the polypeptide chelated potassium compound fertilizer is a mixture of various fertilizers. The fertilizer particles are of different sizes and have inconsistent weights. During the rapid feeding process, the fertilizer is unevenly distributed, resulting in slow weighing speed and low weighing accuracy. It is necessary to transfer the polypeptide chelated potassium compound fertilizer to a weighing scale for weighing, which results in low weighing efficiency. Utility Model Content

[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1:

[0032] See Figure 1-5A quantitative weighing device for discharging potassium-chelated compound fertilizer containing peptides includes a support 1, on which a feeding box 2 is fixedly mounted. The lower left and right side walls of the feeding box 2 are inverted cone-shaped to facilitate the accumulation of fertilizer inside the feeding box 2 at the center for discharge. An inlet 21 is provided on the upper side wall of the feeding box 2, and a feeding hopper 22 is fixedly connected to the side wall of the feeding box 2. The feeding hopper 22 is used to guide the fertilizer released from the compound fertilizer discharging pipe into the feeding box 2. A discharge port 23 is provided at the bottom of the feeding box 2 for unloading. The discharge port 23 is connected to the discharge pipe 24, which has a rectangular cross-section. A lifting adjustment plate 3 is installed inside the discharge box 2. A drive mechanism 4 for raising and lowering the lifting adjustment plate 3 is installed at the top of the discharge box 2. Two vertically placed discharge plates 5 are spaced apart at the bottom of the lifting adjustment plate 3. The two discharge plates 5 are parallel to each other, and their lower ends pass through the discharge port 23 and partially insert into the discharge pipe 24. The area between the two discharge plates 5 is the discharge zone. The outer walls of the two discharge plates 5 are flush with the left and right inner walls of the discharge pipe 24. The sidewalls are fitted with a small clearance. The front and rear end faces of the two unloading plates 5 are fitted with the front and rear end faces of the unloading pipe 24 and the unloading box 2 with a small clearance. A weighing trough 6 is provided at the lower end of the unloading pipe 24. Two tension sensors 7 are provided on both sides of the weighing trough 6. The tension sensors 7 are commercially available devices with two tension ends. The lower end of each tension sensor 7 is connected to the weighing trough 6, and the upper end is connected to the unloading pipe 24. A discharge port 61 is provided at the bottom of the weighing trough 6, and a discharge mechanism 8 is provided at the discharge port 61. The weighing tank 6 is used to discharge the weighed polypeptide chelated potassium compound fertilizer. The lifting adjustment plate 3 is driven by the drive mechanism 4 to raise the two discharge plates 5, which can release the polypeptide chelated potassium compound fertilizer in the discharge box 2 into the discharge pipe 24 and then into the weighing tank 6. The weight change in the weighing tank 6 is measured in real time by the tension sensor 7, which can realize the quantitative weighing of the polypeptide chelated potassium compound fertilizer in the weighing tank 6. The weighing speed is fast, the weighing accuracy is high, and the weighing can be carried out while the material is being discharged, resulting in high weighing efficiency.

[0033] In this utility model, further, see... Figure 3The drive mechanism 4 includes a motor 41, a drive gear 42, a driven gear 43, a lead screw 44, and a nut seat 45. The motor 41 is located on the top of the feeding box 2. The output shaft of the motor 41 passes through the top plate of the feeding box 2 and is inserted into the feeding box 2 and coaxially fixedly connected to the drive gear 42. Two vertically arranged lead screws 44 are arranged on both sides of the drive gear 42. The upper end of each lead screw 44 is rotatably connected to a bearing seat on the top plate of the feeding box 2. Two driven gears 43 are arranged on the two lead screws 44. Both driven gears 43 can mesh with the drive gear 42 for transmission. The lower end of each lead screw 44 extends downward and passes through a guide hole on the lifting adjustment plate 3 to extend below the lifting adjustment plate 3. A nut seat 45 is spirally sleeved on the lead screw 44. The nut seat 45 can be positioned relative to the lead screw. The screw 44 moves up and down in a spiral motion. The nut seat 45 is fixedly connected to the lifting adjustment plate 3. The screw 44 and the nut seat 45 on the lifting adjustment plate 3 are screwed together in a spiral transmission. The nut seat 45 is connected to the screw 44 through a ball screw pair. The output shaft of the screw 44 is driven to rotate by the motor 41, which drives the drive gear 42 to rotate. During the rotation of the drive gear 42, it meshes with the two driven gears 43, which drives the two screws 44 to rotate. The rotation of the two screws 44 can be screwed together with the two nut seats 45 to drive the lifting adjustment plate 3 to rise or fall. The lifting adjustment plate 3 can drive the two unloading plates 5 to open the unloading port 23 and release the fertilizer in the feeding box 2 into the unloading pipe 24 and into the weighing tank 6 for weighing. The discharge accuracy is high and the discharge process is highly controllable.

[0034] In this utility model, further, see... Figure 5 The feeding mechanism 8 includes a feeding plate 81, a telescopic rod 82, and a hinge 83. One end of the feeding plate 81 is rotatably connected to the weighing trough 6 via the hinge 83. Two telescopic rods 82 are provided on both sides of the feeding plate 81. One end of each telescopic rod 82 is hinged to a first hinge seat provided on the feeding plate 81, and the other end is hinged to a first hinge seat provided on the side wall of the weighing trough 6. The telescopic rods 82 are controlled by the controller to drive the feeding plate 81 to rotate downward around the hinge 83, so as to quickly discharge the fertilizer weighed in the weighing trough 6, which is convenient for the next weighing and to clean the weighing trough 6 in advance.

[0035] In this utility model, further, see... Figure 4 Two discharge ports 51 are provided on the side walls of the two discharge plates 5. The fertilizer in the feed box 2 can be easily fed into the discharge pipe 24 at a constant flow rate through the discharge ports 51. The size of the discharge ports 51 can be adjusted by the side wall of the discharge pipe 24, which can also prevent the discharge ports 23 from being blocked.

[0036] In this utility model, further, see... Figure 1A controller 9 is installed on the side wall of the feeding box 2. The controller 9 is a PLC programmable controller. Automatic quantitative weighing can be achieved by setting a preset weight. The tension sensor 7, motor 41, and telescopic rod 82 are all electrically connected to the controller 9 and controlled by the controller 9. The tension sensor 7 detects the weight change of fertilizer in the weighing tank 6 in real time and feeds it back to the controller 9. The controller controls whether the motor 41 works according to the weight of the weighed fertilizer. At the same time, the controller 9 controls the telescopic rod 82 to open or close the feeding port of the weighing tank 6.

[0037] In this utility model, the preferred embodiment is described below. Figure 1 The telescopic rod 82 is an electric push rod, which facilitates automatic control of the discharge plate 81 to open the bottom discharge port of the weighing tank 6, saving discharge time and making the discharge process highly automated.

[0038] As can be seen from the above technical solution, during use, the fertilizer released from the compound fertilizer discharge pipe through the feed hopper 22 is introduced into the discharge box 2. Then, the controller 9 controls the motor 41 to drive its output shaft to rotate, which drives the drive gear 42 to rotate. During the rotation of the drive gear 42, it meshes with the two driven gears 43, which drives the two lead screws 44 to rotate. The rotation of the two lead screws 44 can be mutually screw-driven with the two nut seats 45 to drive the lifting adjustment plate 3 to rise. The lifting adjustment plate 3 drives the two discharge plates 5 to open the discharge port 23 and release the fertilizer in the discharge box 2 into the discharge pipe 24 in a quantitative manner. When the tension sensor 7 detects that the polypeptide chelated potassium compound fertilizer entering the weighing tank 6 has reached the predetermined weight, the controller 9 controls the drive mechanism 4 to drive the two discharge plates 5 to move downward and close the two discharge ports 51. Then, the controller 9 controls the telescopic rod 82 to extend and open the discharge port of the weighing tank 6. After the discharge is completed, the discharge port of the weighing tank 6 is closed, and the above steps are continued to perform quantitative weighing.
