Description

Technical Field

[0001] This utility model relates to the technical field of drug storage and transportation equipment, specifically to a powder transport vehicle. Background Technology

[0002] In the pharmaceutical, chemical, and food industries, the transfer of powdered materials is a common production process. Current methods for transferring pharmaceutical powders typically involve loading them into transfer vehicles or storage containers for short-distance transport or temporary storage.

[0003] However, medicinal powders, especially those that are hygroscopic or sticky, are prone to accumulating and clumping at the bottom and inside of containers during transport and settling due to vibration, compression, and their own physical properties. This not only causes difficulties in discharging the powder, requiring manual intervention to clear blockages and affecting production efficiency, but also the clumped powder can affect the accuracy of subsequent weighing, mixing, or packaging processes, and may even affect the quality of the final product.

[0004] Therefore, existing technologies suffer from problems such as powder clumping during transport, poor discharge, and impact on subsequent use, which urgently need to be improved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a powder transfer vehicle that can stir the powder during the transfer process to prevent the powder from clumping and facilitate subsequent use and discharge.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A powder transport vehicle, comprising: Mobile base; The medicine storage tank has a filling port with a top cover and a discharge port with a bottom cover. The medicine storage tank is mounted and fixed on a mobile base. The stirring rod structure comprises a stirring rod structure, a rotation drive mechanism, and a reciprocating push-pull mechanism. After the stirring rod structure is movably installed inside the medicine storage tank, it is driven to rotate and simultaneously reciprocate left and right through the cooperation of the rotation drive mechanism and the reciprocating push-pull mechanism installed on the medicine storage tank.

[0007] As an improvement, the medicine storage tank is a cylindrical structure with closed ends that is laid down to be horizontal along the central axis and is fixed to a movable base by multiple support legs.

[0008] As an improvement, the stirring rod structure includes a central shaft and stirring blades; the stirring blades are long, straight plates, and after being inclined relative to the side view, multiple blades are evenly fixed along the circumference and axial direction of the central shaft; the central shaft passes through through holes reserved at both ends of the medicine storage tank.

[0009] As an improvement, the stirring rod structure also includes a brush, fixed to the free end of the stirring blade, used to brush off the powder adhering to the inner wall of the storage tank. This not only achieves a stirring effect on the powder but also effectively prevents the powder from adhering to the inner wall of the storage tank.

[0010] As an improvement, the reciprocating push-pull mechanism includes a push-pull motor, an eccentric wheel, a push-pull sleeve, and a connecting shaft. The push-pull motor is mounted and fixed to the right side of the medicine storage tank, with its output shaft fixedly connected to the drive shaft of the eccentric wheel. The right end of the central shaft is rotatably connected to a connecting shaft fixed to the side wall of the push-pull sleeve. After the eccentric shaft of the eccentric wheel passes through the push-pull sleeve, it is confined within the sleeve and reciprocates up and down. This allows the stirring rod structure to stir along the axial direction of the medicine storage tank.

[0011] As an improvement, the rotation drive mechanism includes a rotation drive motor, a sleeve, and a limiting rod. After the rotation drive motor is driven and connected to the left end of the central shaft, a sleeve is fixed on the outer wall of the motor housing, and a limiting rod fixed on the left side wall of the storage tank is movably fitted inside the sleeve. This allows the stirring rod structure to stir along the circumference of the storage tank.

[0012] It is worth mentioning that the push-pull motor and rotary drive motor in this technical solution are both existing devices in common knowledge, and their use and control methods are all existing technologies.

[0013] The advantages of this utility model compared with the prior art are as follows: 1. This novel invention features a stirring rod structure capable of both rotational and axial reciprocating motion, enabling dynamic stirring of the powder during transport or while it is stationary. This combined motion breaks up the static state of the powder, effectively dispersing initially formed clumps and preventing the formation of new clumps, ensuring that the powder remains loose at all times.

[0014] 2. The inclined design and combined motion of the stirring blades in this novel design guide and push the powder during discharge, making the powder flow more smoothly. Simultaneously, the brush at the end of the stirring blades scrapes away powder adhering to the inner wall of the storage tank, reducing material waste and facilitating subsequent cleaning.

[0015] 3. This novel design cleverly integrates the rotary drive and reciprocating push-pull mechanism at both ends of the medicine storage tank, resulting in a compact structure that does not occupy additional space. It utilizes an eccentric wheel and push-pull sleeve to convert rotary motion into linear motion, and achieves power transmission that combines rotation and movement through the cooperation of the sleeve and the limiting rod. The mechanism operates stably and reliably. Attached Figure Description

Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] A powder transfer vehicle mainly consists of a mobile base 1, a medicine storage tank 2, a stirring rod structure, a rotation drive mechanism, and a reciprocating push-pull mechanism.

[0024] Among them, the movable base 1 is as follows Figure 1 As shown, it is easy to move. The medicine storage tank 2, as the core container, has a filling port 4 at the top, which is sealed by the top cover 3; and a discharge port 6 at the bottom, which is controlled to open and close by the bottom cover 5. The medicine storage tank 2 is preferably a horizontally placed cylindrical structure, and is stably supported on the mobile base 1 by multiple support legs 7. Handles 18 are also fixed on the front and rear outer walls of the medicine storage tank 2 for easy manual pushing.

[0025] The stirring rod structure is movably installed inside the medicine storage tank 2, and it includes a central shaft 8 and multiple stirring blades 9. The stirring blades 9 are long, straight plates, and are evenly fixed to the central shaft 8 circumferentially and axially at a certain angle (relative to the side view). To clean the inner wall, a brush 10 is also fixed at the free end (outermost end) of the stirring blades 9. Both ends of the central shaft 8 extend to the outside of the tank through pre-set through holes on the left and right side walls of the medicine storage tank 2.

[0026] The rotary drive mechanism, used to drive the stirring rod structure to rotate, mainly includes a rotary drive motor 15, a sleeve 16, and a limiting rod 17. The rotary drive motor 15 is connected to the left end of the central shaft 8 via a coupling or similar means to drive its rotation. A sleeve 16 is fixed to the outer wall of the motor housing of the rotary drive motor 15, and this sleeve 16 is slidably fitted onto a limiting rod 17 fixed to the left side wall of the medicine storage tank 2. This structure allows the entire motor and central shaft 8 to slide axially on the limiting rod 17, while ensuring effective torque transmission.

[0027] The reciprocating push-pull mechanism drives the stirring rod structure to reciprocate axially. It mainly includes a push-pull motor 11, an eccentric wheel 12, a push-pull sleeve 13, and a transfer shaft 14. The push-pull motor 11 is fixed to the right side of the storage tank 2, and its output shaft is connected to the drive shaft of the eccentric wheel 12. The right end of the central shaft 8 is connected to a transfer shaft 14 via a bearing, and the transfer shaft 14 is fixed to the side wall of the push-pull sleeve 13. The eccentric shaft on the eccentric wheel 12 extends into and is confined within the push-pull sleeve 13. When the push-pull motor 11 drives the eccentric wheel 12 to rotate, the circular motion of the eccentric shaft is converted into a horizontal, reciprocating linear motion through the push-pull sleeve 13, thereby driving the central shaft 8 and the entire stirring rod structure on it to move left and right.

[0028] Working Principle: After the medicine powder is loaded into the storage tank 2, the rotary drive motor 15 and the push-pull motor 11 can be started simultaneously during transportation or when needed. The rotary drive motor 15 drives the stirring rod structure to rotate continuously, stirring the medicine powder; at the same time, the push-pull motor 11 drives the stirring rod structure to move back and forth along the central axis through the eccentric wheel 12 and the push-pull sleeve 13. The combination of these two movements causes the stirring blades 9 to form a complex motion trajectory inside the tank, greatly enhancing the stirring effect on the medicine powder and effectively breaking up any clumps that may form. The brush 10 moves accordingly, constantly scraping the inner wall of the tank to prevent the medicine powder from adhering. When discharge is required, the bottom cover 5 is opened, and the loose medicine powder flows out smoothly under the guidance of gravity and the stirring blades.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
