Description

Technical Field

[0001] This utility model relates to the field of feed trucks, and in particular to an auger anti-collision mechanism. Background Technology

[0002] With the development of technology, modern livestock farming has adopted an intensive feeding model. Powdered or granular feed is transported from feed production plants to farms using feed trucks. This significantly reduces transportation costs and labor intensity, while also improving transportation efficiency. After transportation, the feed is typically moved from the feed trucks using an auger. Augers are generally electrically controlled, but improper operation or operation in confined environments can increase the torque during rotation, causing the auger to collide and potentially damage it, affecting its use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a screw conveyor anti-collision mechanism in light of the current state of the technology.

[0005] The aforementioned components achieve the following effects: The installation of an auger assembly on the tank facilitates material discharge; the rotation protection structure prevents collisions that could affect the auger assembly's operation; the flange and tension adjustment assembly allow for adjustment of the flange's prestress; and in the event of a collision, if the torque generated by the auger assembly's rotation exceeds the flange's prestress, the flange will slip, preventing further rotation and thus protecting the auger assembly.

[0006] Preferably, the tension adjustment assembly includes a fixed base, a bolt, a butterfly spring, and a pressure plate; the fixed base is provided with a fixing hole; the bolt passes through the fixing hole; the butterfly spring is disposed between the bolt and the fixed base; and the pressure plate is disposed at the lower end of the fixing hole.

[0007] The aforementioned components achieve the following effects: by providing a fixing seat, they limit and fix the bolts, disc springs, and pressure plates; by providing fixing holes, they fix the bolts; and by providing disc springs, they adjust the prestress of the flange.

[0008] Preferably, the auger assembly includes a horizontal auger, a vertical auger, and a lifting auger; the vertical auger is provided with a rotating structure; and the rotating protection mechanism is provided at the upper end of the rotating mechanism of the vertical auger.

[0009] The aforementioned components achieve the following effects: by incorporating horizontal, vertical, and lifting augers, they facilitate the transport of feed; and by employing a rotating structure, they drive the auger assembly to rotate.

[0010] Preferably, the flange is mounted on a vertical auger; at least one end face of the flange abuts against the pressure plate.

[0011] The effect achieved by the above components is that by setting the flange on the vertical auger and having one end face in contact with the pressure plate, prestress is generated.

[0022] like Figures 1 to 3 As shown, this utility model provides an auger anti-collision mechanism, including a tank body 1; a rotatable auger assembly 2 is provided on the tank body 1, and a rotation protection mechanism 3 is provided on the auger assembly 2; the rotation protection mechanism 3 includes a flange 31 and a tension adjustment assembly 32; the flange 31 is mounted on the auger assembly 2 through the tension adjustment assembly 32; the prestress of the flange 31 is adjusted through the tension adjustment assembly 32; when the auger assembly 2 rotates, if the torque generated when the auger assembly 2 turns exceeds the prestress applied to the flange 31 by the tension adjustment assembly 32, the tension adjustment assembly 32 and the flange 31 slip, causing the auger assembly 2 to stop rotating. By installing an auger assembly 2 on the tank body 1, material discharge is facilitated; a rotation protection structure is installed to prevent the auger assembly 2 from being affected by collisions; a flange 31 and a tension adjustment assembly 32 are installed so that the tension adjustment assembly 32 can adjust the prestress of the flange 31; after a collision, if the torque generated by the rotation of the auger assembly 2 exceeds the prestress of the flange 31, the flange 31 will slip, and the auger assembly 2 will stop rotating, thus preventing damage to the auger assembly 2 and achieving the purpose of protecting the auger assembly 2.

[0023] The tension adjustment assembly 32 includes a fixed base 33, a bolt 34, a butterfly spring 35, and a pressure plate 36. The fixed base 33 has a fixing hole 37. The bolt 34 passes through the fixing hole 37. The butterfly spring 35 is positioned between the bolt 34 and the fixed base 33. The pressure plate 36 is positioned at the lower end of the fixing hole 37. The fixed base 33 serves to limit and fix the bolt 34, butterfly spring 35, and pressure plate 36. The fixing hole 37 secures the bolt 34. The butterfly spring 35 adjusts the prestress of the flange 31.

[0024] The auger assembly 2 includes a horizontal auger 21, a vertical auger 22, and a lifting auger 23; a rotating structure 24 is provided on the vertical auger 22; and a rotating protection mechanism 3 is provided on the upper end of the rotating mechanism of the vertical auger 22. The horizontal auger 21, vertical auger 22, and lifting auger 23 are configured to transport feed; and the rotating structure 24 is configured to drive the auger assembly 2 to rotate.

[0025] The flange 31 is mounted on the vertical auger 22; at least one end face of the flange 31 abuts against the pressure plate 36. By mounting the flange 31 on the vertical auger 22 and having one end face abut against the pressure plate 36, prestress is generated.

[0027] In this embodiment: when the user uses the auger assembly 2, the first rotating part 25, the second rotating part 26 and the lifting auger 23 rotate through the rotating structure. If the vertical auger 22 or the lifting auger 23 collides, the torque between the auger and the flange 31 exceeds the prestress between the flange 31 and the pressure plate 36.

[0028] The prestress between flange 31 and pressure plate 36 is increased or decreased by rotating bolt 34 to compress or expand the compression spring.
