Description

Technical Field

[0001] This utility model relates to the field of quantitative packaging technology, specifically to a quantitative packaging dust removal device for powdered soil conditioners. Background Technology

[0002] In modern agricultural production, soil degradation is becoming increasingly serious. As an important product for improving soil conditions and enhancing soil fertility, powdered soil conditioners are experiencing growing market demand. Pre-packaged powdered soil conditioners are a crucial step in the production process to ensure stable product quality and compliance with market standards. However, this process generates a large amount of dust. This dust not only causes raw material loss but also damages the production workshop environment, harms the health of operators, and even adversely affects the surrounding ecological environment. Therefore, dust removal equipment is an indispensable component of pre-packaged powdered soil conditioner production lines.

[0003] Currently, most dust collection devices used for quantitative packaging of powdered soil conditioners are designed for fixed production scenarios and single packaging specifications, resulting in a fixed and unadjustable dust collection range. In actual use, these devices rely primarily on pre-set suction port positions, duct diameters, and negative pressure adsorption parameters to collect dust. Once the equipment is installed and debugged, its effective dust collection area is fixed and cannot be flexibly adjusted according to changes in actual production needs.

[0004] However, in the actual production of powdered soil conditioners, dynamic changes in production needs are very common. For example, different batches of products may require different packaging specifications. When switching from small packages of 20kg / bag to large packages of 50kg / bag, the material drop point and dust diffusion radius at the packaging station will change significantly. The production line may also adjust the packaging speed according to the order volume. Changes in packaging speed will directly affect the rate of dust generation and the diffusion range. At the same time, in some production scenarios, it is necessary to alternately package different types of powdered soil conditioners. These different types of products have differences in characteristics such as fineness and specific gravity, which will lead to different dust drift trajectories. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative packaging dust removal device for powdered soil conditioners, solving the problems mentioned in the background art.

[0008] The dust removal mechanism includes multiple dust suction plates, each dust suction plate having multiple dust suction holes on the side facing the quantitative packaging tank. An exhaust cavity is formed inside the dust suction plate, and the dust suction holes are connected to the exhaust cavity. Multiple dust suction plates are hinged to the outside of the quantitative packaging tank via hinge seats. At least one electric push rod is provided on the support frame.

[0009] The output end of the electric push rod is connected to a transmission ring, and the side of the dust suction plate away from the quantitative packaging tank is hinged to a drive rod through a hinge seat. The end of the drive rod away from the dust suction plate is hinged to the transmission ring through a hinge seat.

[0010] An extraction component is also provided on the outside of the quantitative packaging can, and the extraction component is connected to multiple dust collection plates.

[0011] Furthermore, the number of dust-collecting plates is six, and they are arranged in a ring array on the outside of the quantitative packaging can.

[0012] Furthermore, the top and bottom projections of the dust collection plate are both arc-shaped.

[0013] Furthermore, the extraction assembly includes an annular tube disposed on the support frame, and at least one exhaust pipe is connected to the side of the dust suction plate away from the quantitative packaging tank.

[0014] Furthermore, the exhaust pipe is a plastic flexible hose.

[0015] Furthermore, one of the aforementioned dust collection panels has two exhaust pipes.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. The quantitative packaging dust removal device for this powdered soil conditioner uses an electric push rod to drive the dust suction plate angle adjustment. It can accurately adapt to the dust diffusion range according to changes in packaging specifications, packaging speed, and product type, solving the drawbacks of traditional fixed dust removal devices that are limited to a single scenario and cannot be adjusted, thus improving the versatility of the device.

[0018] 2. The dust removal device for the quantitative packaging of this powdered soil conditioner has six dust suction plates arranged in a circular array with an arc design, forming a fully enclosed dust removal area around the quantitative packaging tank, preventing dust from escaping from blind spots.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The dust removal device for quantitative packaging of powdered soil conditioner in this embodiment can dynamically adjust the dust removal area according to the dust diffusion range during the quantitative packaging process of powdered soil conditioner, so as to achieve efficient dust removal.

[0026] Specifically, it includes a support frame 1, a quantitative packaging tank 2, a dust removal mechanism 3, and an extraction component 4. The quantitative packaging tank 2 is installed inside the support frame 1 and is the core component for the quantitative output of powdered soil conditioner. It has a discharge port at the bottom, which can transport a predetermined amount of powdered soil conditioner into the packaging container. During the quantitative packaging process, dust is easily generated when the powder falls from the discharge port. The dust removal mechanism 3 is arranged around the quantitative packaging tank 2 to capture this diffused dust.

[0027] In detail, the dust removal mechanism 3 includes six suction plates 301, at least one electric push rod 302, a transmission ring 303, and six drive rods 304. The six suction plates 301 are arranged in a ring array on the outside of the quantitative packaging tank 2. The top and bottom projections are arc-shaped, which is adapted to the arc-shaped outer wall of the quantitative packaging tank 2, and can cover the dust diffusion area to the maximum extent. Each suction plate 301 has multiple suction holes on the side facing the quantitative packaging tank 2, and an exhaust cavity is opened inside. The suction holes are connected to the exhaust cavity, and dust can enter the exhaust cavity through the suction holes.

[0028] In actual setup, the six dust collection plates 301 are arranged in a ring array, with the top and bottom being arc-shaped, forming an all-around dust collection ring around the quantitative packaging tank 2, preventing dust from escaping due to blind spots in the dust collection area.

[0029] Furthermore, the dust suction plates 301 are all hinged to the outside of the quantitative packaging tank 2 via hinge seats, and can rotate around the hinge point to adjust the dust suction angle. The side of the dust suction plate 301 away from the quantitative packaging tank 2 is hinged to a drive rod 304 via a hinge seat. The end of the drive rod 304 away from the dust suction plate 301 is hinged to the transmission ring 303 via a hinge seat. The electric push rod 302 is mounted on the support frame 1, and its output end is connected to the transmission ring 303 for transmission, which can push the transmission ring 303 to move up and down along the axial direction of the quantitative packaging tank 2.

[0030] In actual setup, when the electric push rod 302 pushes the transmission ring 303 to move up and down, the drive rod 304 will drive the dust suction plate 301 to rotate around the hinge point, thereby changing the angle between the dust suction plate 301 and the quantitative packaging tank 2. When the transmission ring 303 moves up, the drive rod 304 pushes the dust suction plate 301 to unfold away from the tank, expanding the dust removal range. When the transmission ring 303 moves down, the drive rod 304 pulls the dust suction plate 301 to retract towards the tank, reducing the dust removal range.

[0031] More specifically, the extraction component 4 is used to extract the dust collected by the dust collection plate 301, and includes an annular pipe 401, an exhaust pipe 402, and a connecting pipe 403. The annular pipe 401 is mounted on the support frame 1 and distributed around the quantitative packaging tank 2. Each dust collection plate 301 has at least one exhaust pipe 402 connected to the side away from the quantitative packaging tank 2. The annular pipe 401 has a connecting pipe 403 on its outer side, which can be connected to an external dust collector to form a negative pressure environment.

[0032] Preferably, one of the dust collection plates 301 has two exhaust pipes 402. The exhaust pipes 402 are made of plastic hoses, which can be flexibly deformed with the rotation of the dust collection plate 301 and are connected to the annular pipe 401.

[0033] In actual setup, the exhaust pipe 402 is a plastic flexible hose that connects the dust suction plate 301 and the annular pipe 401. The length of the plastic flexible hose 402 meets the maximum arc swing range of the dust suction plate 301, so that the hose 402 will not break or fail to seal due to the angle adjustment of the dust suction plate 301. The annular pipe 401 is set around the quantitative packaging tank 2 and can connect the exhaust pipes 402 of six dust suction plates 301 at the same time. This allows the dust collected by multiple dust suction plates to be concentrated into the annular pipe 401, and then connected to the external dust collector through the connecting pipe 403 to form a unified negative pressure dust suction system to improve dust extraction efficiency.

[0034] The working principle of the above embodiments is as follows:

[0035] 1. Based on current production needs, start the electric push rod 302. Its output end pushes the transmission ring 303 to move upward along the axis of the quantitative packaging tank 2. The moving ring 303 drives the six drive rods 304 to deflect upward synchronously. The end of the drive rod 304 away from the transmission ring pushes the dust suction plate 301 to rotate outward around the hinge point connected to the quantitative packaging tank 2 until the dust suction holes of the dust suction plate 301 cover the maximum range of dust expected to spread. Then the electric push rod 302 stops working, the transmission ring 303 locks in position, and the dust suction plate 301 maintains the current angle.

[0036] 2. Connect the connecting pipe 403 to the external dust collector and start the dust collector. A negative pressure environment is formed in the exhaust cavity of the annular pipe 401, the exhaust pipe 402, and the suction plate 301. At this time, the quantitative packaging tank 2 starts to work. The predetermined amount of powdered soil conditioner falls from the bottom outlet into the packaging container. The dust generated during the falling process spreads to the surroundings. Under the action of negative pressure, the spread dust enters the exhaust cavity through the dust suction hole on the side of the suction plate 301 facing the tank, and then flows into the exhaust pipe 402 along the exhaust cavity. Since the exhaust pipe 402 is a plastic hose, it can remain stable with the angle of the suction plate 301. The dust is connected, and the dust flows into the annular pipe 401 through the exhaust pipe 402, and then is sucked into the external negative pressure equipment through the connecting pipe 403 to complete the dust collection. If the production needs change, the electric push rod 302 is started again, and its output end pulls the transmission ring 303 to move downward. The transmission ring 303 pulls the dust suction plate 301 to rotate closer to the quantitative packaging tank 2 through the drive rod 304, reducing the dust suction range. If the packaging speed is increased or the product is changed to fine powder, the electric push rod 302 is controlled to push the transmission ring 303 upward, expanding the opening angle of the dust suction plate 301 to ensure that the dust is always within the effective dust removal range.
