Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a feed screw conveyor. Background Technology

[0002] Feed processing is the process of processing various feed raw materials into feed products that meet the nutritional needs and breeding requirements of animals through a series of treatments and processing techniques. In the feed processing process, semi-finished or finished feed is generally transported by a screw conveyor. The screw shaft in the screw conveyor rotates to transport the material.

[0003] Traditional feed screw conveyors typically have fixed, non-adjustable discharge ports. Because the specifications, heights, and placement of hoppers vary within feed processing workshops, fixed, non-adjustable discharge ports struggle to accurately deliver feed to hoppers at different positions and heights. This leads to feed splashing and scattering during transport, resulting in waste. Furthermore, in feed processing workshops with complex layouts, or when production processes are adjusted to change the direction and destination of feed delivery, traditional screw conveyors cannot adapt quickly and effectively, severely hindering the smooth operation of the production process.

[0004] Therefore, it is necessary to provide a new feed screw conveyor to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a feed screw conveyor with anti-splash and flexible feeding angle adjustment.

[0010] Preferably, a sealing gasket is installed between the upper arc plate and the lower arc plate, and the sealing gasket is fixedly installed on the upper arc plate.

[0011] Preferably, a locking mechanism is installed on the lower arc plate. The locking mechanism includes an arc-shaped locking plate fixedly installed on the lower arc plate. The arc-shaped locking plate is fixed to the side wall of the lower arc plate and close to the conveying pipe. A locking bolt is threadedly connected to the arc-shaped locking plate, and the end of the locking bolt abuts against the outer side wall of the conveying pipe.

[0012] Preferably, the locking bolt has a cross groove.

[0013] Preferably, the feeding tube is equipped with an adjustment mechanism for controlling the extension and retraction of the feeding sleeve, a sliding rod is fixedly installed on the feeding tube with clearance fit, and a sliding cavity is opened on the sliding rod.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 7This utility model provides a feed screw conveyor, which includes: a feed pipe 1, a drive motor 14 for driving the internal screw shaft of the feed pipe 1 fixedly installed at the end of the feed pipe 1, a feed inlet 11 and a feed outlet 12 opened on the feed pipe 1, a bracket 15 fixedly connected to the feed pipe 1, a plurality of circumferentially distributed connecting rods 13 fixedly installed at the feed outlet 12, a rotating mechanism 4 installed on the feed outlet 12, and a feed screw that communicates with the feed outlet 12 and can rotate around the feed screw through the rotating mechanism 4. The feeding pipe 1 has a rotating adjustable feeding pipe 2, and the feeding pipe 2 is fitted with a telescopic adjustable feeding sleeve 3; the rotating mechanism 4 includes two annular limiting blocks 41 fixed on both sides of the discharge port 12, and the feeding pipe 1 is rotatably connected to an upper arc plate 42 and a lower arc plate 43 with a rotating groove 44, and the upper arc plate 42 and the lower arc plate 43 are detachably connected, the annular limiting block 41 is engaged in the rotating groove 44 and is rotatably connected to the upper arc plate 42 and the lower arc plate 43, and the lower arc plate 43 is fixedly connected to the feeding pipe 2.

[0028] It should be noted that: the bracket 15 of this utility model is used to support the entire screw conveyor, the drive motor 14 is used to control the rotation of the drive screw shaft to convey feed. Feed is put into the feed inlet 11 and conveyed by the rotation of the screw shaft. The discharge outlet 12 is used for feeding, and the feed is discharged from the discharge outlet 12 through the discharge pipe 2 and the discharge sleeve 3. The discharge sleeve 3 can be adjusted according to actual needs so that it extends into the receiving hopper to prevent the falling feed from splashing out. When the height of the receiving hopper is low, the discharge sleeve 3 can be adjusted to extend into the receiving hopper for receiving. When the height of the receiving hopper is high or it is inconvenient to place the receiving hopper directly on the discharge sleeve 3, the discharge sleeve 3 can be adjusted to extend into the receiving hopper for receiving. When the feed is at its lowest point, the angle of the feed pipe 2 can be adjusted by releasing the restriction on the rotating mechanism 4, and the feed sleeve 3 can be adjusted so that the feed sleeve 3 is tilted and extended into the receiving hopper for restriction before the feed is fed. This utility model, through the telescopic adjustable feed sleeve 3, can be adjusted according to the height of the receiving hopper so that it extends into the receiving hopper, effectively preventing the falling feed from splashing out and keeping the working environment clean. The rotating mechanism 4 allows the feed pipe 2 to rotate and adjust its angle around the conveying pipe 1. When the height of the hopper is high or the position is inconvenient, the feed pipe 2 can be tilted and adjusted so that the feed sleeve 3 can extend into the receiving hopper, meeting the feeding needs in different scenarios and improving the applicability and flexibility of the conveyor.

[0029] Among them, the feed falling from the feed sleeve 3 is not only the receiving hopper, but also other receiving containers that can receive the feed falling from the discharge port 12.

[0030] The rotating mechanism 4 is mainly composed of an upper arc plate 42 and a lower arc plate 43. The upper arc plate 42 and the lower arc plate 43 form a collar to wrap around the discharge port 12. The ring limit block 41 is locked in the rotating groove 44 on the upper arc plate 42 and the lower arc plate 43 and can rotate, so that the feeding tube 2 can be rotated and adjusted as needed. The upper arc plate 42 and the lower arc plate 43 can be disassembled and separated.

[0031] The discharge port 12 is located on the conveying pipe 1, which will damage the strength of the conveying pipe 1 to a certain extent. By fixing and installing the connecting rod 13 in the discharge port 12, the conveying pipe 1 at the discharge port 12 is reinforced to ensure the stability of the conveying pipe 1.

[0032] Among them, the inner wall of the lower arc plate 43 and the inner cavity of the feed pipe 2 are smoothly transitioned. The smooth transition structure has no unevenness or sharp edges and corners, which can prevent feed from being stuck in the gaps or corners of the connection during the conveying process. This helps to keep the inside of the conveyor clean and reduce problems such as deterioration and mold caused by feed residue, thereby ensuring the quality and hygiene of the feed.

[0033] The lower part of the feed sleeve 3 has a gradually narrowing inner cavity and a smooth transition of the inner wall. As the lower inner cavity narrows, the feed will be more concentrated when it falls and will not easily scatter in all directions. This is very helpful for accurately placing the feed into the specific receiving container, reducing feed spillage and waste, and keeping the working environment clean.

[0034] In the embodiments of this utility model, please refer to Figure 4 Ears are fixedly installed at the ends of the upper arc plate 42 and the lower arc plate 43 that are close to each other, and the ear pieces located on the upper arc plate 42 and the lower arc plate 43 are fixedly connected by connecting bolts 45.

[0035] It should be noted that the lugs on the upper arc plate 42 and the lower arc plate 43 can be connected and fixed by connecting bolts 45, so that the upper arc plate 42 and the lower arc plate 43 are mated and fixed, which facilitates the installation and disassembly of the upper arc plate 42 and the lower arc plate 43.

[0036] In the embodiments of this utility model, please refer to Figure 4 A sealing gasket 46 is installed between the upper arc plate 42 and the lower arc plate 43, and the sealing gasket 46 is fixedly installed on the upper arc plate 42.

[0037] It should be noted that the gap between the upper arc plate 42 and the lower arc plate 43 after they are joined is filled by the sealing gasket 46 to prevent the rotating mechanism 4 from having gaps after installation and causing feed to leak out.

[0038] In the embodiments of this utility model, please refer to Figure 3 and Figure 6A locking mechanism 6 is installed on the lower arc plate 43. The locking mechanism 6 includes an arc-shaped locking plate 61 fixedly installed on the lower arc plate 43. The arc-shaped locking plate 61 is fixed on the side wall of the lower arc plate 43 and close to the feed pipe 1. A locking bolt 62 is threaded on the arc-shaped locking plate 61, and the end of the locking bolt 62 abuts against the outer side wall of the feed pipe 1.

[0039] It should be noted that by rotating the locking bolt 62, the end of the locking bolt 62 is no longer in contact with the outer wall of the conveying pipe 1. Then, by slightly loosening the connecting bolt 45, the feeding pipe 2 can be rotated to adjust the feeding sleeve 3. Tightening the connecting bolt 45 can also limit the upper arc plate 42 and the lower arc plate 43. Tightening the locking bolt 62 so that its end is only in contact with the outer wall of the conveying pipe 1 can limit and reinforce the feeding pipe 2, improve the stability of the feeding pipe 2, and prevent it from rotating.

[0040] The locking bolt 62 has a cross groove 621; the locking bolt 62 can be turned by using a flathead screwdriver or a Phillips screwdriver, making it easy to rotate the locking bolt 62.

[0041] In the embodiments of this utility model, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 An adjustment mechanism 5 for controlling the extension and retraction of the feeding sleeve 3 is installed on the feeding pipe 2. A slide rod 51 with clearance fit is fixedly installed on the feeding pipe 2, and a sliding cavity 52 is opened on the slide rod 51. A connecting block 53 is fixedly installed on the feeding sleeve 3. A stop block 54 is installed on the rear side of the slide rod 51, and a square slider 55 fixedly connected to the stop block 54 is slidably connected in the sliding cavity 52. ​​A limiting post 56 that abuts against the outer wall of the connecting block 53 is threadedly connected to the square slider 55.

[0042] It should be noted that the square slider 55 can only slide along the slide cavity 52. ​​The stop block 54, which is fixedly connected to the square slider 55, blocks the rear side of the slide rod 51 to restrict the square slider 55. With the help of the limiting post 56, which is threadedly connected to the square slider 55, the square slider 55 is restricted in the slide cavity 52. ​​Loosening the limiting post 56 can adjust the feeding sleeve 3. Tightening the limiting post 56 makes the stop block 54 close to the rear side wall of the slide rod 51 and the limiting post 56 close to the outer side wall of the connecting block 53, thus connecting and restricting the feeding sleeve 3 and the feeding tube 2 so that they cannot slide relative to each other.

[0043] The working principle of the feed screw conveyor provided by this utility model is as follows:

[0044] Feed is fed into the feed inlet 11 and transported by the rotating screw shaft. The feed outlet 12 is used for feeding, and the feed is discharged from the outlet 12 through the feed pipe 2 and the feed sleeve 3. The feed sleeve 3 can be adjusted as needed so that it extends into the feed receiving hopper to prevent the falling feed from splashing out. When the height of the receiving hopper is low, the feed sleeve 3 can be adjusted to extend into the receiving hopper for receiving. When the height of the receiving hopper is high or it is inconvenient to place the receiving hopper directly under the feed sleeve 3, the angle of the feed pipe 2 can be adjusted by releasing the restriction on the rotating mechanism 4, and the feed sleeve 3 can be adjusted so that the feed sleeve 3 is tilted and extended into the receiving hopper for restriction before feeding.

[0045] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
