Technical Field

The invention relates to the technical field of old-age-assisting feeding equipment, in particular to an extrusion crushing rod for an auxiliary feeding device.

Background

With the increasing of the aging problem of the population, the elderly are increasingly paid more attention in home care and diet, and many elderly only eat some liquid diet due to tooth aging or other physical reasons. Due to the inherent fluidity of the liquid food, for the old with easily shaking hands, the liquid food has certain difficulty in eating by using the traditional tableware, and if the liquid food is fed by others, the choking risk of the old is increased.

At present, the auxiliary feeding device is a feasible scheme for assisting the old to feed autonomously. The auxiliary food taking device drives the extrusion rod to rotate through the motor, so that food is extruded to take food in an auxiliary way.

The extrusion rods can be divided into three categories of equidistant depth-variable rods, equal-depth pitch-variable rods and depth-variable pitch-variable rods. Although the three types of rods have simple structure, flexible design, low cost and high extrusion conveying efficiency, the three types of rods have single function and can only finish the one-way conveying of food. In some situations where food is to be broken, the existing squeeze bar generally does not have the ability to break the food due to the limitations of the existing squeeze bar structure, so that the existing auxiliary feeding device is not practical in this situation.

At present, in the market, the occasions of connecting the rod with the crushing structure are not many, and a plurality of crushing structures are in the form of blades, but in the crushing occasion of food, the crushing degree of the blades only reaches granulation, and under the condition that high-degree crushing is needed to achieve argillization, a new crushing structure is needed to perform high-degree crushing. Therefore, it is important to provide a crushing rod for an auxiliary feeding device.

the first conveying section and the second conveying section have the same structure and are of single-spiral worm structures;

the first shearing section is also of a single spiral worm structure, the lead of the first shearing section is smaller than that of the first conveying section, and the height of the screw edge of the first shearing section is smaller than that of the screw edge of the first conveying section;

Detailed Description

The following describes in more detail embodiments of the present invention with reference to the schematic drawings. The advantages and features of the present invention will become more apparent from the following description. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.

As shown in fig. 1-3, the crushing rod for the auxiliary feeding device provided by the embodiment of the invention is rotatably installed in the communication hole of the auxiliary feeding device, and the length-diameter ratio of the crushing rod is 22: 1. The extrusion crushing rod is sequentially divided into a connecting section 1, a first conveying section 2, a first shearing section 3, a second shearing section 4, a second conveying section 5, a solid-liquid mixing section 6 and a supporting section 7 along the axial direction. The support section 7 is inserted into a bearing in the auxiliary feeding device.

The first conveying section 2 and the second conveying section 5 are identical in structure and are both of a single-spiral worm structure. The lead of the first conveying section 2 and the lead of the second conveying section 5 are both 20 mm. The first conveying section 2 and the second conveying section 5 each have a longer pitch and a deeper flight, which may enhance the conveying capacity. The first shearing section 3 is also of a single spiral worm structure, the lead of the first shearing section 3 is smaller than that of the first conveying section 2, and the height of the screw ridge of the first shearing section 3 is smaller than that of the screw ridge of the first conveying section 2.

Specifically, the first shearing section 3 adopts a small-pitch and low-pitch structure. The lead of the first shearing section 3 is 10mm, which is reduced by times compared with the lead of the first conveying section 2. Meanwhile, the inner wall of the corresponding position of the communicating hole is also provided with a convex edge with the equal distance of 10mm, and the convex edge is positioned between the two spiral edges, so that the food is crushed for the first time under the action of the transverse shearing force of the spiral edges and the convex edge in the pushing process. The structure design can realize the granulation of the food and prepare for the food pugging.

Because there is the shaft shoulder in the junction of first shearing section 3 with first transmission section 2, it has a subsection helicla flute 8 to open at the kneck of first shearing section 3 with first transmission section 2, is convenient for food to get into first shearing section 3.

The second shearing section 4 is a cylindrical body formed after a plurality of longitudinal grooves which penetrate through the cylinder along the axial direction are equidistantly formed on the circumferential surface of the cylinder, and the shaft diameter of the second shearing section 4 is consistent with the inner diameter of the connecting through hole and is in clearance fit with the connecting through hole. When the first crushed food passes through the longitudinal grooves of the second cutting section 4, the direction of the food is perpendicular to the cutting direction, and the second crushing of the food is completed under the strong cutting action, and the food is basically muddy and pressed into the second conveying section 5.

The solid-liquid mixing section 6 is provided with a plurality of rectangular teeth which are distributed at intervals along the axial direction. The food that will be compressed is scattered through the rectangle tooth during rotation, and the hot water juice that fully fuses with the drippage for shriveled food is full succulent, and the taste is better.

Furthermore, the end of the connecting section 1 is provided with a square hole for connecting with the output shaft of the low-speed motor, and the low-speed motor is installed in the auxiliary feeding device and drives the extrusion crushing rod to rotate. Install square boss adapter on the output shaft of low-speed motor, insert square boss adapter in the square hole can be connected with the broken pole transmission of extrusion.

In summary, under low-speed state, functions such as cutting breakage, conveying to food can be accomplished to the crushing pole of extrusion, and wearing and tearing calorific capacity is little moreover. The first conveying section 2 and the second conveying section 5 have the characteristics of large screw pitch and deep screw groove, so that the conveying amount of food can be increased, and the conveying efficiency is improved. Set up two shearing sections, crushing effect is good, and the setting of the interior bead of UNICOM's through-hole and the spiral shell arris of first shearing section 3 is highly little, and residual food is few, goes out to eat efficiently. Finally, the crushing pole of extrusion of this application is provided with solid-liquid mixing section 6, and the hot water juice that the food of being convenient for and extrusion process drip fully fuses.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
