Detailed Description

The technical scheme of the present invention will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that all directional indicators (such as up, down, left, right, front, and rear …) in the present invention are merely used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly. Furthermore, the description of "preferred," "less preferred," and the like, herein is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "preferred", "less preferred" may include at least one such feature, either explicitly or implicitly.

Referring to fig. 1 to 3, the invention provides a pet feeder capable of preventing materials from being blocked, comprising a feed cylinder 1, a hopper 2 arranged on the feed cylinder 1, a screw 3 arranged in the feed cylinder 1, and a driving device capable of driving the screw 3 to rotate so as to convey materials in the feed cylinder 1 forward, wherein the feed cylinder 1 is provided with a feed inlet 101 for conducting the hopper 2 and the feed cylinder 1, the feed cylinder 1 is provided with a discharge outlet 102 positioned in front of the feed inlet 101, the screw 3 comprises a central shaft 31, a helical blade 32 arranged on the outer side wall of the central shaft 31 and positioned in front of the feed inlet 101, and a pushing block 33 arranged at the rear of the central shaft 31, and the front part of the pushing block 33 is provided with a stirring convex part 331 capable of stirring the materials at the feed inlet 101. Specifically, the screw blade 32 is located between the inlet 101 and the outlet 102, and a step is provided between the front end of the screw surface 332 and the front end surface of the push block 33 so that a vertex angle 333 is formed at the front end of the screw surface 332. The apex angle 333 is located at the position of the inlet 101.

The working principle of the invention is as follows: the material in the hopper 2 can fall into the material cylinder 1 under the action of gravity, and the material in the material cylinder 1 is pushed forward and falls out of the discharge hole 102 by the rotation of the screw 3. The screw blade is not arranged at the position, opposite to the feed inlet 101, on the central shaft 31, which is beneficial to the material in the hopper 2 to fall into the feed cylinder 1, and meanwhile, the screw 3 rotates and simultaneously agitates the material at the feed inlet 101 through the agitating convex part 331, so that the material can be effectively prevented from being blocked at the feed inlet 101.

Further, the front side of the stirring protrusion 331 has a screw surface 332 capable of pushing the material forward. With such a structure, the forward thrust of the screw 3 to the material can be raised, and at the same time, the amount of the material output from the discharge port 102 per one turn of the screw 3 can be precisely controlled by controlling the pitch and width of the screw 332.

Further, the hopper 2 and the barrel 1 are integrally formed, the inside of the hopper 2 has an inclined charge level 201, and the inclined charge level 201 extends into the barrel 1. By adopting the structure, the clamping caused by the connecting seam between the hopper 2 and the charging barrel 1 is avoided.

Preferably, the number of stirring protrusions 331 is two or more, typically 2-3, and all stirring protrusions 331 are evenly distributed around the central axis 31.

As a preferred embodiment of the invention, the drive means comprises a motor 41, the motor 41 being connected to the screw 3 via a gear set. Specifically, the gear set includes a first bevel gear 42 connected to the rear end of the central shaft 31, and a second bevel gear 42 connected to the output end of the motor 41 and meshed with the first bevel gear 42. The central shaft 31 is screwed with the first bevel gear 42 and the screw 3 rotates to cause the first bevel gear 42 to have a movement tendency to screw.

The foregoing description of the preferred embodiments of the present invention should not be construed as limiting the scope of the invention, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the following description and drawings or any application directly or indirectly to other relevant art(s).
