Description

Technical Field

[0001] This utility model relates to the field of fertilizer production technology, and in particular to a weighing and packaging device for solid water-soluble fertilizer. Background Technology

[0002] Water-soluble fertilizer is a type of multi-element compound fertilizer that can completely dissolve in water. It dissolves rapidly in water, is more easily absorbed by crops, and has a relatively high absorption and utilization rate. More importantly, it can be applied to facility agriculture such as sprinkler irrigation and drip irrigation to achieve integrated water and fertilizer management, resulting in water-saving, fertilizer-saving, and labor-saving efficiency. An existing fertilizer weighing and packaging device, with publication number CN211468845U, uses a U-shaped support and four connecting rods. The compression of the electric telescopic rod on the U-shaped support increases the distance between the four connecting rods. An adhesive layer on the inner side of the four connecting rods holds the upper outer edge of the fertilizer packaging bag, thus opening the bag's opening. However, this design relies solely on the adhesive layer for support and fixation. After a certain weight of fertilizer is filled, the weight may become too great, causing the adhesive to weaken and the fertilizer packaging bag to fall, spilling fertilizer and resulting in waste. Utility Model Content

[0003] The purpose of this invention is to provide a solid water-soluble fertilizer weighing and packaging device to solve the above problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

A support platform 10 is provided on the upper surface of the guide rods 8.

[0023] In this embodiment: the screw feeding mechanism 2 includes a hopper 21 fixed on the mounting frame 1. The hopper 21 is used to store fertilizer. A conveying box 22 is provided on the lower surface of the hopper 21. A rotating shaft 23 is installed inside the conveying box 22. A spiral blade 24 is installed on the outside of the rotating shaft 23. The rotating shaft 23 is used to drive the spiral blade 24 to rotate. The spiral blade 24 is used to convey fertilizer. A power component 25 is connected to one end of the rotating shaft 23. A discharge pipe 26 is fixed to the bottom of one side of the conveying box 22. A first solenoid valve 27 is installed on the discharge pipe 26. The first solenoid valve 27 is used to control the discharge of fertilizer from the discharge pipe 26. The conveying box 22 is fixed on the mounting frame 1. The conveying box 22 is connected to the bottom of the hopper 21. The rotating shaft 23 is rotatably connected to the conveying box 22. The spiral blade 24 is fixed on the rotating shaft 23. The specification bucket 3 is detachably connected to the discharge pipe 26.

[0024] In this embodiment: the spreading mechanism 5 includes a housing 51 fixed on the mounting bracket 1, a cylinder 52 mounted on the housing 51, an active slider 53 fixed at the output end of the cylinder 52, the cylinder 52 driving the active slider 53 to move, driven sliders 54 are provided on opposite sides of the active slider 53, the active slider 53 pushing the driven sliders 54, a fixed plate 55 is provided on the driven slider 54, and an arc-shaped support plate 56 is mounted on the fixed plate 55, the driven slider 54 driving the arc-shaped support plate 56 to move. 56 is used to open the fertilizer packaging bag. The active slider 53 has V-shaped guide rails on both sides, and the driven slider 54 has a V-shaped groove on one side. The V-shaped guide rail of the active slider 53 is slidably connected to the inner side of the V-shaped groove of the driven slider 54. The driven slider 54 is slidably connected to the housing 51.

[0025] The working principle and usage process of this utility model are as follows: First, the fertilizer packaging bag is placed outside the arc-shaped support plate 56. The cylinder 52 of the opening mechanism 5 extends, driving the active slider 53 to move, causing the driven slider 54 to slide to both sides. This causes the arc-shaped support plate 56 on the fixed plate 55 to move to both sides, opening the fertilizer packaging bag. Then, the power component 25 of the screw feeding mechanism 2 is started, driving the rotating shaft 23 to rotate, which in turn drives the spiral blade 24 to rotate and transport the fertilizer. The first solenoid valve 27 is opened to allow the fertilizer to be introduced into the specification barrel 3 through the discharge pipe 26. When the specification barrel 3 is full, the first solenoid valve 27 is closed and the second solenoid valve 4 is opened for filling. During the filling process, the fertilizer packaging bag contacts the support table 10, which can support the fertilizer packaging bag. After filling is completed, the cylinder 52 retracts, driving the active slider 53 to retract, driving the driven slider 54 to slide inward, thereby driving the arc-shaped support plate 56 to move inward, which can loosen the filled fertilizer packaging bag.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
