RO123663B1 - Fruit crusher with comblike counterknife and rotor with profiled helically-arranged rigid cutting blades - Google Patents

Abstract

The invention relates to a fruit crusher with comblike counterknife and rotor with profiled helically arranged rigid cutting blades, meant to be used, in particular, in individual households and also in the industry concerned. According to the invention, the crusher comprises a drum (B) having one or several rows of profiled rigid cutting blades (1) arranged helically at a certain pitch (p) and under a certain angle (beta), and some comb-shaped counterknives (C), where, upon rotation, the cutting blades (1) pass through the comb teeth while simultaneously entraining the crushed product.

Description

The invention relates to a fruit grinder with a comb-like strut, and a rotor with rigid, profiled knives, helical arrangement.

It is known a fruit grinder consisting of a drum whose surface is made of specially profiled sheet. By rotating the drum, the fruit table is driven and, due to the Surface profiled with some teeth, a process of breaking and breaking takes place.

The crushing takes place the entire length of the roller, the process requiring considerable effort from the operator.

This type of crushers has the disadvantage that the drum is difficult to perform, as the tooth profile is usually obtained through heavy plastic deformation procedures. The execution costs are high, the maneuvering effort is high, and the productivity quite limited.

US 252128 A is disclosed, which discloses a machine for cutting and slicing apples, potatoes, fruits and the like, consisting of a suitable frame, mounted on support legs, and provided with bearings for an axle supporting a flywheel and a cylinder provided with a finger pin, arranged in two sets or diametrically opposed series, arranged radially! on the rotary cylinder. A cross member is fixed transversely on the frame, at a certain distance from the cylinder, and is provided with a series of slots located at an equal distance between them, in which some knives are fixed. A hopper supplies the cutting machine with vegetable matter.

Also known is the document CH 245027 A, which discloses an apparatus for the extraction of fruit juice, especially fruit, made up of an elongated casing, supported on four legs, a rotating cylinder provided with cylindrical bars arranged on a helical cylinder, radially , and a sieve through which the resulting juice flows through the funnel into various containers.

The technical problem solved by the invention consists in the manufacture of a grinder that ensures an improved process of cutting, breaking and crushing of the product, at the same time with a better driving of the product and its re-casting.

The fruit crusher with a comb-type strut, and a rotor with rigid, profiled, helical casters, removes the above disadvantage by the fact that the drum has one or more rows of rigid, profiled, helical castings, and the counter has a comb-like shape. ; when rotating the knives pass between the teeth of the comb, at the same time driving the crushed product.

The concave shape of the knives, and the proper sizing determine a high intensity breaking and crushing, the helical arrangement ensuring a continuous, progressive process, with minimal effort.

The fruit crusher with a comb-like strut, and a rotor with rigid, profiled, helical-shaped knives, according to the invention, has the following advantages:

- the helical arrangement ensures a safe and continuous crushing step, progressively;

- very high productivity, with minimal effort;

- simple construction;

- high reliability;

- In the case of manual operation, it can work both ways, for right-handed, but also left-handed operators.

The following is an example of an embodiment of the fruit crusher in connection with FIGS. 1-3, which represents:

FIG. 1, side view of the fruit crushers;

- fig, 2, a view from the direction A of the crushers;

FIG. 3 is a side view of a knife.

RO 123663 Β1

The fruit crushers with comb type counter, and rotor with rigid, profiled knives, 1 helical arrangement, according to the invention, has a drum B with one or more rigid cut lines 1, helical arranged, with a step p and at an angle β in front of generators. 3

The knives 1 have a special profile, as part of an axial section through a rotating hyperboloid with a blade, and are positioned so as to comply with the following: 5

- on the radius drum r is fixed with the small base, this one having a curvature of the same value r and which practically copies its surface; 7

- the work plane to form an angle of 90 ° with its generators.

The drum B is mounted in two bearings 2 fixed to the rod 3, Parallel to the drum are 9 arranged two countercuts C among whose teeth the blades of the drum pass. depending on the direction of rotation, one counter is active and the other passive. 11

The shape of the knives with hollow cutting, concave and the sizing of the passage places of the plywood, guarantees the smooth running of the cutting, breaking and crushing process of the 13 product, and, at the same time, determines the entrainment of the product and its re-casting.

In order to minimize the effort required, the countertops are placed on a lower plane 15 relative to the axis of the drum, at a distance x and the continuity of the crushing process is ensured by the existence of deflectors 4 for directing the product to the bunker. 17
