Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer production, in particular to a weighing and packaging device for fertilizer production. Background Art

[0002] Fertilizers are functional substances that directly or indirectly provide plant nutrients, improve soil properties, and increase plant yield and quality. Fertilizers can be divided into organic fertilizers, inorganic fertilizers, organic-inorganic compound fertilizers, etc. according to their sources and chemical composition. Organic fertilizers are mainly derived from animal and plant residues, while inorganic fertilizers are made through chemical synthesis or extraction of minerals, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, etc.

[0003] In the prior art, fertilizers are often quantitatively packaged using weighing and packaging equipment after production is completed. Workers place the packaging bags at the outlet of the hopper, and the clamp on the hopper clamps the packaging belt. The feeder quantitatively feeds fertilizer into the packaging bags through the hopper. After the packaging bags are quantitatively filled with fertilizer, the clamp releases the clamping effect on the packaging bags, and the packaging bags fall onto the conveyor for movement. Workers smooth the opening of the packaging bags, and then the packaging bags are sealed by a sealing machine.

[0004] However, when a small amount of fertilizer is weighed and packaged, a smaller packaging bag is required. The distance between the packaging bag and the conveyor is large. When the packaging bag falls from the hopper, the packaging bag tends to topple over, and the fertilizer overflows from the packaging belt. In addition, workers need to bend over to smooth the smaller packaging bag opening, which is time-consuming and labor-intensive for workers and affects the packaging efficiency of the fertilizer.

[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1-6 As shown, a weighing and packaging device for fertilizer production includes: a base plate 1, a feeder 7 and a clamping component.

[0029] A side panel 2 is provided on the top of the bottom plate 1. The side panel 2 is provided with two groups. Adjustment components are fixedly connected on both sides of the side panel 2. The inner wall of the side panel 2 is connected with a conveyor belt 3. The feeder 7 is provided on the top of the conveyor belt 3. The bottom end of the conveyor belt 3 is fixedly connected with a drop hopper 6. The two sides of the feeder 7 are connected with a clamper 25. The side end of the feeder 7 is fixedly connected with a feeding pipe 8. When the fertilizer is packaged in small quantities, the fertilizer needs to be packaged in smaller bags. The worker controls the adjustment component to adjust the height of the side panel 2. The side panel 2 adjusts the height with the conveyor belt 3, thereby Ensure that the distance between the conveyor belt 3 and the drop hopper 6 is compatible with the smaller packaging bag. The worker places the packaging bag at the bottom of the drop hopper 6. The clamp 25 automatically clamps the packaging bag. The feeding pipe 8 conveys the fertilizer to the feeder 7. The feeder 7 quantitatively conveys the fertilizer into the packaging bag through the drop hopper 6. The packaging bag contacts the conveyor belt 3 from the bottom of the drop hopper 6, thereby preventing the packaging bag from falling from the drop hopper 6 and tipping over. This ensures the stability of the packaging bag storing fertilizer. When the packaging bag is loaded with fertilizer, the conveyor belt 3 can transport the packaging bag.

[0030] The clamping assembly is arranged on the top of the conveyor belt 3, and the clamping assembly cooperates with the drop hopper 6. In order to avoid workers from smoothing the mouth of the packaging bag, when the packaging bag is loaded with fertilizer, the clamping assembly automatically clamps the packaging bag. At the same time, the clamper 25 releases the clamping of the packaging bag. When the clamping assembly clamps the packaging bag, the packaging bag mouth will not bend or misaligned. The clamping assembly moves synchronously with the packaging bag. When the packaging bag starts to be sealed by the sealing machine, the clamping assembly contacts the packaging bag to clamp it and automatically resets. The clamping assembly improves the work efficiency of packaging fertilizers with packaging bags and avoids increasing labor costs.

[0031] In some specific embodiments, a cylinder 9 is provided between the feed pipe 8 and the base plate 1, and the upper and lower ends of the cylinder 9 are fixedly connected to the feed pipe 8 and the base plate 1 respectively. The base plate 1 and the clamping assembly are provided with two groups of support rods 12, and the two groups of support rods 12 are respectively located on both sides of the clamping assembly and the upper and lower ends are fixedly connected to the base plate 1 and the clamping assembly respectively. A number of rollers 26 are equidistantly connected along the length direction of the side plate 2 in the conveyor belt 3, and the two ends of the rollers 26 are respectively connected to the side plate 2. The base plate 1 provides support for the feeder 7 and the feed pipe 8 through the cylinder 9, and the base plate 1 provides support for the clamping assembly through the support rods 12, wherein the rollers 26 can be driven to rotate by the motor of the prior art, and the rollers 26 drive the conveyor belt 3 to move.

[0032] In some specific embodiments, the adjustment component includes: a support column 4, an adjustment column 5, a threaded rod 17 and a control member 21. The bottom end of the support column 4 is fixedly connected to the bottom plate 1, and the support column 4 is slidably connected to the inner wall of the adjustment column 5. The support column 4 is axially provided with a threaded hole 16, and the threaded rod 17 is slidably connected to the inner wall of the threaded hole 16. The top of the threaded rod 17 is fixedly connected to the control member 21, and the threaded rod 17 is cooperated with the adjustment column 5. The adjustment column 5 is fixedly connected to the side plate 2. A rotating groove 18 is provided on the top of the adjustment column 5. A rotating plate 19 is clamped and connected in the rotating groove 18 and is rotatably connected to the rotating plate 19. The rotating plate 19 is fixedly connected to the outer wall of the threaded rod 17. A sealing plate 20 is fixedly connected to the outer wall of the bottom of the control member 21. The diameter of the sealing plate 20 is larger than the inner diameter of the rotating groove 18. The sealing plate 20 fits with the adjusting column 5. When the adjustment assembly is running, the worker controls the control member 21 to rotate, and the control member 21 moves with the threaded rod 17 and the rotating plate 19 The screw rod 17 is connected with the screw hole 16 to move in the height direction, thereby leading the rotating plate 19 to move in the height direction. The rotating plate 19 is connected with the adjusting column 5 to move in the height by the clamping connection with the rotating groove 18, thereby leading the adjusting column 5 to move in the height with the side plate 2. The support column 4 slides along the inner wall of the adjusting column 5 to provide a limiting effect for the adjusting column 5 to prevent the adjusting column 5 from rotating on its own. When the screw rod 17 stops rotating, the screw rod 17 provides support for the adjusting column 5 by the threaded connection with the screw hole 16. Among them, the sealing plate 20 can seal the inside of the adjusting column 5 by fitting with the support column 4 to prevent dust and impurities from entering the adjusting column 5 and affecting the threaded connection between the screw rod 17 and the screw hole 16. The clamping connection between the rotating plate 19 and the inner wall of the rotating groove 18 provides a limiting effect for the top end of the screw rod 17 to ensure the axial stability of the screw rod 17.

[0033] In some specific embodiments, the clamping assembly includes: a driver 10, a guide rail 11, a clamping plate 14 and a clamping claw 15.

When the clamping plate 14 is in contact with one end of the packaging bag, the clamping claw 15 rotates to clamp and fix the other end of the packaging bag, and then the driver 10 moves on the guide rail 11, wherein the driver 10 and the packaging bag move synchronously.

[0034] In some specific embodiments, knocking columns 24 are fixedly connected to both sides of the drop hopper 6, and knocking plates 22 are fixedly connected to the inner walls of both ends of the clamp 25. The knocking plates 22 are connected with the knocking columns 24. The knocking plates 22 are provided with rounded corners 23 at one end close to the knocking columns 24. When the clamp 25 clamps the packaging bag, the clamp 25 rotates around the axis of the clamp 25 with the knocking plate 22. The knocking plate 22 has plasticity, and the knocking plate 22 touches and bends to slide over the knocking columns 24. When the clamp 25 releases the clamp on the packaging bag, the knocking plate 22 2 reverse movement and touch the knocking column 24 and bend and slide over. The contact between the knocking plate 22 and the knocking column 24 can knock the knocking column 24, and the vibration generated by the knocking column 24 is transmitted to the drop hopper 6. The vibration can fully drop the fertilizer in the drop hopper 6 from the drop hopper 6 into the packaging bag, avoiding the fertilizer remaining in the drop hopper 6, resulting in insufficient fertilizer loaded in the packaging bag, affecting the quantitative packaging effect of the feeder 7, and the rounded corners 23 of the knocking plate 22 facilitate the knocking plate 22 to bend and slide along the knocking column 24, avoiding the knocking plate 22 from getting stuck.
