Abstract

A meat grinder comprises a short machine body, a short pushing shaft, a kink type handle and a short pushing shaft, wherein, a pressing screw and a pressing cushion are connected by a whorl to reduce effectively the resistance of grinding meat and improve the grinding efficiency with little labor consumption and light hand swing, furthermore the whole weight of the meat grinder is light and the package box has a smaller volume.

Description

Meat grinder

Affiliated technical field

The utility model relates to food processing machinery, especially a kind of meat grinder.

Background technology

Meat grinder is processed the food machinery that meat gruel is used as a kind of, be widely used already, substituted manual cutting, but seen various model meat grinders on the market, housing construction is long and heavy, and the spiral form of cardan shaft also has long spiral, short spiral, double helix etc., but total length is longer, the unreasonable structure of spiral, it is big to exist power consumption, and dressing percentage is low and install and use shortcomings such as inconvenience.The application of the relevant meat grinder that Chinese patent has been announced has 81 more than, but the protection domain of its detailed summary of the invention, claim and the present invention have difference.

Summary of the invention

The utility model provides a kind of meat grinder, has the short cardan shaft of single-screw, few pitch, the short type body of single straight mouthful tubaeform charging aperture, the draw bail of loop type handle and cardan shaft, the fixed structure of the clamping screw of separated type, compress gasket and body.

The technical solution adopted for the present invention to solve the technical problems is:

1, adopt the short type cardan shaft of single-screw, few pitch, this weak point type cardan shaft should meet the effective length (L) of cardan shaft and the ratio of outside diameter (D) is 0.75～1.25.It is the single head spiral that single-screw promptly advances axial screw, and few pitch is that its effective helix angle number is 1.2～2.The major impetus consumption that experiment showed, meat grinder is two aspects, the one, and the cutting resistance when cutting off the meat material; The 2nd, meat material crush resistance, when particularly the meat material presses to round cutting-off tool, some is got in the circular hole of round cutting-off tool, and some is compressed in the surface of round cutting-off tool, on this surface, formed bigger resistance, so select for use the structure of suitable cardan shaft to obtain suitable propulsive force, be to reduce power consumption, improve the chief component of dressing percentage.

2, adopt short housing construction, because the shortening of cardan shaft, the body that matches with it also correspondingly shortens, the effective length of its body (L ') is 0.75～1.25 with the ratio of outlet diameter (D '), the effective length of body is the total length deduction charging aperture length partly of body, and the effective length of cardan shaft is measured, and suggestion is put into cardan shaft in the body, also the length of deduction and the corresponding part of charging aperture.

3, it is tubaeform that the charging aperture of body adopts single straight mouth, promptly one side is straight mouthful, another side is an angle, not only increased the spatial volume at feed entrance place, and owing to aspect clockwise, be straight mouthful, the meat material is entered quickly and smoothly, reduced the intake resistance of meat material, also increase inlet simultaneously.

4, the fixed form of cardan shaft and handle adopts the fixing of loop type, changes bolting in the past, has reduced part, has made things convenient for assembling.

5, thread connection is adopted in the connection of clamping screw and compress gasket, changed original clamping screw is put into body after, again with the way of compress gasket riveting on clamping screw.

The invention has the beneficial effects as follows: reduced the meat grinder resistance, improved meat grinder efficient, so reached consumption power little, hand light, to go out meat fast.Alleviated the complete machine weight of meat grinder on the other hand, reduced feed consumption, the packing box volume that complete machine dispatches from the factory also dwindles.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure 1, clamping screw, 2, compress gasket, 3, handle, 4, short body, 5, short cardan shaft, 6, the cross blade, 7, circular knife, 8, check nut.

The specific embodiment

With reference to Fig. 1, whole meat grinder connects compress gasket (2) by clamping screw (1) and is fixed on desktop or other the firm flat boards.The meat material is from the charging aperture feeding of short body (4), and turning handle (3) drives short cardan shaft (5), rotates together with cross blade (6).Because short cardan shaft is the variable-pitch propeller structure of single thread, few pitch, pitch is by diminishing greatly rapidly, so the meat material is advanced, and being squeezed to the surface of circular knife (7), a part of meat material is got in the aperture of circular knife, because the surperficial formed shearing of cross blade and circular knife aperture, the meat material of soon having been got in the aperture cuts off, after the cross blade turned over aperture, the meat material of another batch was got in the aperture again, and cut so repeatedly meat mincing just are extruded from discharging opening.Fastening screw nut (8) plays and compresses circular knife, adjusts the effect of the shear gap between circular knife and the cross blade.

With reference to Fig. 2, in order to match with short cardan shaft, also adopt short body, promptly the effective length (L ') of short body is 0.75～1.25 with the ratio of outlet diameter (D '), the charging aperture of short body is just tubaeform in short cardan shaft direction, and it laterally is that straight mouthful of list is tubaeform.

With reference to Fig. 3, can be clear that from cutaway view short body charging aperture is tubaeform for single straight mouth, it simultaneously is straight mouthful, and another side is an angle, and straight mouthful one side is exactly charging place of meat material.

With reference to Fig. 4, short its feature of cardan shaft is contraction in length still not, and its effective helix angle also reduces, and its effective length (L) is 0.75～1.25 with the ratio of outlet diameter (D), and short to advance axial screw be single head, and the number of its effective helix angle is 1.2～2.It is the angle-shaped groove that cooperates handle that short cardan shaft afterbody has a projection, handle can be made things convenient for also be inserted in short cardan shaft, and drive short cardan shaft, and in the time will dismantling, as long as angle of handle reversing, outside one group just can be unloaded lower handle.Handle and cardan shaft have been changed in the past by the fixing way of annular screw.

With reference to Fig. 5, handle has an angle-shaped groove at an end that is inserted in short cardan shaft, and loose fit is adopted in the cooperation of the afterbody projection of the width of its angle-shaped groove and short cardan shaft, is convenient to installation and removal.

With reference to Fig. 6, Fig. 7, the top of clamping screw has one section minor thread partly, this minor thread partly has a darker escape in the transition with screw rod, the width of this escape is greater than the thickness of compress gasket, after the minor thread of clamping screw partly is screwed into compress gasket, compress gasket just falls in the escape, because the diameter of escape is less than the internal diameter of compress gasket inside spin, so also just be not easy clamping screw and compress gasket are separated easily.
