Description

Technical Field

[0001] This utility model relates to the technical field of spiral feeding devices, specifically to a spiral feeder. Background Technology

[0002] A screw feeder, also known as a screw conveyor or screw feeding device, is an industrial device that uses the rotation of a screw to achieve quantitative conveying and control of materials. It is mainly used for the continuous metering, batching, and conveying of powdery and granular materials. Its working principle is as follows: after the material enters the trough from the inlet, the rotating screw blades generate axial thrust, pushing the material towards the outlet to achieve feeding or discharging.

[0003] A search revealed a spiral feeding device disclosed in Chinese Utility Model Publication No. CN212100658U, comprising a device body, a fixed support at one end of the device body, and an adjusting support at the other end of the device body. A motor is fixedly installed at one end of the device body, and a rotating rod connected to the motor is provided inside the device body. Spiral blades are provided on the rotating rod. The device body has a feeding structure and a telescopic structure connected to the feeding structure. The device body also has a discharge port.

[0004] Based on the background technology of this patent, it can be seen that the spiral feeding device in the prior art needs to adjust the angle of use according to the usage situation in actual application. However, although the spiral feeding device can adjust the angle of use, it cannot move its position according to the usage situation.

[0005] A spiral feeding device disclosed in Chinese Utility Model Publication No. CN221115643U includes a base, a spiral conveyor body fixedly installed on the top of the base, a storage box provided at the bottom of the spiral conveyor body, a storage cylinder provided on the top of the base, an anti-clogging mechanism provided on the top of the base, and a discharge pipe fixedly installed on the top of the spiral conveyor body.

[0006] As can be seen from the accompanying drawings in the patent specification, although the spiral feeding device can be adjusted in terms of its angle and position according to the usage conditions, the universal wheels at the bottom of the spiral feeding device will continuously shift their position during use due to the lack of braking.

[0007] Therefore, there is an urgent need to improve the existing technology so that the existing screw feeding device can not only adjust the angle of use according to the usage conditions, but also move at any time, and can also brake and generate lateral support force during use.

[0008] Based on this, a screw feeder is proposed. Utility Model Content

The specific technical solution is as follows:

[0056] Example 1

[0057] like Figures 1-5 As shown, an embodiment of this utility model provides a screw feeder, comprising:

[0058] The mobile frame structure 100 consists of a chassis 110, casters 120 rotatably mounted at the four corners of the chassis 110, and a push frame 130 fixedly mounted on one side wall of the chassis 110.

[0068] Example 2

[0069] like Figures 1-5 As shown, the improvements are based on Example 1:

[0070] Furthermore, the spiral feeding assembly 200 includes a spiral feeding tube 210, which is hollow inside and closed at both ends. A conveying auger is rotatably installed inside, and one end of the conveying auger's shaft extends outward through the end of the spiral feeding tube 210 away from the feeding assembly 300.

[0071] The spiral feeding pipe 210 has a feed inlet 220 at the top of the end near the feeding assembly 300 and a discharge port 230 at the bottom of the end away from the feeding assembly 300.

[0072] Both the feed inlet 220 and the discharge outlet 230 are connected to the spiral feed pipe 210.

[0073] The spiral feeding assembly 200 also includes a motor bracket 240 and a drive motor 250. The motor bracket 240 is fixedly installed on the end of the spiral feeding pipe 210 away from the feeding assembly 300. The drive motor 250 is fixedly installed on the motor bracket 240. The output shaft of the drive motor 250 is fixedly connected to the shaft of the outwardly penetrating conveying auger.

[0074] The spiral feeding assembly 200 also includes a connecting base 260, which is fixedly installed on the top of the chassis 110 and on the bottom side of the corresponding feeding assembly 300. The inner sidewalls of the opposite sidewalls of the connecting base 260 each have a connecting shaft 2610. A bushing 270 is sleeved on one inner end of each of the two connecting shafts 2610. The inner end face of each bushing 270 is fixedly connected to the sidewall of the spiral feeding tube 210.

[0075] The spiral feeding assembly 200 also includes a feed hose 290, one end of which is inserted into the feed inlet 220, and the other end of which is connected to the feeding assembly 300.

[0076] In this embodiment, the conveying auger inside the spiral feeding pipe 210 rotates under the drive of the drive motor 250, conveying the material entering from the feed port 220 along the pipe body and finally discharging it from the discharge port 230.

[0077] The rotation of the spiral feeding tube 210 is achieved by the cooperation between the connecting shaft 2610 of the connecting base 260 and the bushing 270, providing a basis for angle adjustment;

[0078] The feed hose 290 enables material communication between the feed box 310 and the spiral feed pipe 210, and can adapt to position changes during angle adjustment;

[0079] The drive motor 250 is fixed on the spiral feeding pipe 210 by the motor bracket 240, and its output shaft drives the conveying auger to rotate, providing power for material conveying.

[0080] The connecting base 260 provides a mounting base for the spiral feeding tube 210 to rotate, and the cooperation between the connecting shaft 2610 and the bushing 270 realizes the rotational connection of the spiral feeding tube 210.

[0081] The feed hose 290 enables material transfer between the discharge port 3120 of the feed box 310 and the feed port 220 of the spiral feed pipe 210, and has a certain degree of flexibility to adapt to positional changes when the angle of the spiral feed pipe 210 is adjusted.

[0082] Furthermore, the feeding assembly 300 includes a feeding box 310, which has a filling port 3110 on one side of the top and a discharge port 3120 on one side of the bottom corresponding to the feeding port 220.

[0085] In this embodiment, the feeding box 310 adds material through the filling port 3110, and the material enters the spiral feeding pipe 210 through the discharge port 3120 and the feeding hose 290;

[0086] The box bracket 330 fixes the feeding box 310 onto the chassis 110.

[0087] Furthermore, the feeding assembly 300 also includes a wedge-shaped guide plate 320, which is fixedly installed at the bottom of the inner cavity of the feeding box 310, and the inclined surface of the wedge-shaped guide plate 320 is set towards the discharge port 3120.

[0088] In this embodiment, the inclined surface of the wedge-shaped guide plate 320 faces the discharge port 3120, so that the material in the feed box 310 gathers at the discharge port 3120 under the action of gravity, which facilitates the smooth entry of the material into the feed hose 290 and prevents material residue.

[0089] Furthermore, the spiral feeding assembly 200 also includes an upper U-shaped connector 280, which is fixedly installed on the bottom side of the spiral feeding pipe 210 near the discharge port 230.

[0090] The angle adjustment component 400 includes a hydraulic cylinder 410. The bottom of the cylinder of the hydraulic cylinder 410 has a connecting block, and a lower U-shaped connecting seat 420 is movably connected to the connecting block. The bottom of the lower U-shaped connecting seat 420 is fixedly installed on the top of the chassis 110, and the piston rod of the hydraulic cylinder 410 is movably connected to the upper U-shaped connecting seat 280.

[0091] Furthermore, a lower pin 430 is movably installed between the connecting block and the lower U-shaped connecting seat 420.

[0092] In this embodiment, the lower U-shaped connecting seat 420 is movably connected to the connecting block via a lower pin 430, providing a connection point for the bottom end of the angle adjustment component 400.

[0093] In this embodiment, the cylinder of the hydraulic cylinder 410 in the angle adjustment component 400 is movably connected to the chassis 110 through the lower U-shaped connecting seat 420 and the lower pin 430, and the piston rod is movably connected to the spiral feeding tube 210 through the upper U-shaped connecting seat 280 and the upper pin 440. By extending and retracting the hydraulic cylinder 410, the spiral feeding tube 210 is driven to rotate around the connecting shaft 2610 of the connecting base 260, thereby adjusting the operating angle of the spiral feeding assembly 200.

[0094] Furthermore, an upper pin 440 is movably mounted between the piston rod end of the hydraulic cylinder 410 and the upper U-shaped connecting seat 280.

[0095] In this embodiment, the upper U-shaped connecting seat 280 is movably connected to the piston rod of the hydraulic cylinder 410 through the upper pin 440, providing a connection point for the top end of the angle adjustment component 400.

[0096] Furthermore, the spiral feeding assembly 200 also includes a discharge pipe 2100, one end of which is inserted into the discharge port 230, and the other end of which extends outward.

[0097] More specifically, the unloading pipe 2100 is Z-shaped.

[0098] In this embodiment, the discharge pipe 2100 guides the material discharged from the discharge port 230 to a designated position, and the Z-shaped structure can adapt to different discharge space requirements.

[0100] Each hydraulic lifting cylinder 520 is fixedly connected to its corresponding fixed base 510 after being installed.

[0101] In this embodiment, the hydraulic lifting cylinder 520 in the lateral support braking component 500 is embedded in the fixed base 510, with its piston rod facing downward. When lifting, the piston rod drives the support leg 530 to move downward, so that the support leg 530 contacts the ground, braking the mobile frame structure 100 and providing lateral support force to ensure the stability of the device during use. When retracting, the piston rod drives the support leg 530 to move upward, without affecting the movement of the caster wheel 120.

[0102] Example 3

[0103] like Figures 1-5 As shown, the improvements are based on Example 2:

[0105] Furthermore, the vibrating component 600 is a vibrating motor 610, which is fixedly installed on one side of the top of the feeding box 310.

[0106] In this embodiment, the vibration motor 610 is installed on one side of the top of the feeding box 310. When working, it generates vibration, which causes the material in the feeding box 310 to shake, preventing the material from clumping in the feeding box 310 or blocking the discharge port 3120, and ensuring that the material enters the feeding hose 290 smoothly.

[0107] Example 4

[0108] like Figures 1-5 As shown, the difference from Example 1 is:

[0109] Furthermore, the 120 omnidirectional wheels are replaced with AGV self-drive wheel sets. The AGV self-drive wheel sets can be selected from the PTD series differential steering wheels manufactured by Suzhou Phoenix Power Industry Co., Ltd.

[0110] In this embodiment, after the AGV self-drive wheel set replaces the universal wheel 120, the device can move automatically without manual pushing, which improves the automation level and ease of movement of the device and is suitable for automated production scenarios.

[0111] The different embodiments described above can be combined, substituted, or used in combination with each other.

[0112] Work steps:

[0113] like Figures 1-5 As shown, the mobile frame structure 100 enables the movement of the device (in Embodiment 4, the AGV self-drive wheel set can move automatically);

[0114] The feeding assembly 300 stores materials and conveys them to the spiral feeding pipe 210 of the spiral feeding assembly 200 through the wedge guide plate 320 and the feed hose 290. The vibrating element 600 can prevent the material in the feeding box 310 from getting blocked.

[0115] Driven by the drive motor 250, the screw feeding assembly 200 conveys the material to the discharge pipe 2100 through the conveying auger. The hydraulic cylinder 410 of the angle adjustment component 400 can adjust the angle of the screw feeding assembly 200 to adapt to different feeding requirements.

[0116] The lateral support braking component 500 is lifted during device use to achieve braking and lateral support, ensuring device stability. It retracts during movement without affecting movement.

[0117] In summary:

[0121] IV. High degree of automation (Example 4): The AGV self-drive wheel set is adopted to realize the automatic movement of the device, which improves the level of automation and is suitable for automated production environment.

[0122] V. Reasonable structural design: The connection and cooperation between the components are reasonably designed, such as the feed hose 290 adapting to angle adjustment and the Z-shaped structure of the discharge pipe 2100, which makes the device more efficient and practical in realizing its functions.
