Description

The invention relates to the food industry, in particular to devices for cracking, crushing and grinding shells of pine nuts and can be used in everyday life and in conditions of small procurement.

A device for cracking the shell of a nut in domestic conditions according to the patent No. 2045928 MKP6 A47J / 26, published October 20, 1995 (application No. 93041174/13 of August 13, 1993), which contains handles mounted on one axis with the possibility of rotation, a socket for premises of a nut formed on the handles and made in the form of a truncated cone.

A device for splitting and grinding food products according to patent No. 2084196 MKP6 A47 J / 26, published on July 20, 1997 (application No. 9304433/13 of July 21, 1993), which contains two handles with jaws and an axis of rotation of one handle relative to the other. The upper handle is provided with a lower jaw, and the lower handle is equipped with an upper jaw, while teeth are installed in the front parts of the jaws, and the jaws are provided with two sockets.

The disadvantage of these devices is the inconvenience of placing a nut for cracking in the singular, that is, only after cracking one nut, you can put the next nut to crack. The cracking of the walnut shell by these devices is possible only when controlling the compression-unloading forces of the handles. The spread and rebound of the nut shell after cracking is not controlled. Lack of loading and receiving hopper.

A device for cracking nutshells is known. The invention relates to the food industry, in particular to devices for cracking nuts, patent for the invention of the Russian Federation No. 2454897, IPC A23N 5/00, published on July 10, 2012). A device for cracking a nutshell contains a shaft on bearing bearings and a transport mechanism, drive, and a hopper rigidly fixed thereon. The transported mechanism is made in the form of a drum. The device is additionally equipped with a pressure plate and a vibrator with adjustable amplitude, rigidly fixed to it. The pressure plate is located with a gap on the outside of the drum. An ejector is installed inside the drum, which is made with the possibility of reciprocating motion and located with a gap with respect to its inner surface. Along the periphery of the drum, cone-shaped through cells are evenly placed. The ejector at the end is equipped with a brush.

A disadvantage of the known device is the design complexity, the purpose of this device to work in industrial volumes (the impossibility of free use in everyday life), the use of the device is possible only if there is an additional mechanism - a vibrator.

Closest to the claimed technical solution is a method of mechanical cleaning of pine nuts from shells and a device for its implementation according to the patent for the invention of the Russian Federation No. 2140757, IPC A23N 5/00, published on 10.11.1999 (as of 07.11.2012 - the patent has expired) , which contains a loading hopper, feeder, housing, conveying element, a mechanism for breaking the nut in the form of a shaft mounted for rotation and fixed above a flat working surface, adjustable supports for setting the gap, it is necessary to break the nut between the shaft and the flat working surface, and the flat working surface has a slope for feeding the nut into the destruction zone, the feature is that the housing is made in the form of a box without one wall, the shaft is covered with rubber and fixed in the side walls of the housing, the housing contains a bed in the form of a flat working surface, fixed to the housing by a piano loop, and the working surface of the bed and the shaft form a gap having a constant value along the length of the shaft and necessary for the destruction of the nut, is adjustable A support in the form of a screw for changing the angle between the base of the body and the bed, has a sieve with holes for the core of the peeled walnut kernel and a fan, the feeder has movable and fixed sectors, and the rotation of the working shaft and the rotation of the feeder are kinematically interconnected via a flexible shaft walnut is carried out due to the vibrator, which are equipped with a bed and sieve.

The disadvantages of the known device is the complexity of the design and the use of the device is possible only if there is an additional mechanism - adjustable supports, vibration drive and additional elements: elastic shaft cover, piano loop and sieve. The absence of protrusions on the shaft makes it difficult for cedar nuts to enter (tighten) into the space between the shaft and the working surface (in the zone of destruction of the nut).

The technical task of the invention is to simplify the design while expanding the scope.

The problem is solved in that the device for cracking the shells of pine nuts, comprising a housing, a shaft installed in the housing, a drive, loading and receiving hoppers, a splitting element, which is made in the form of at least one rectangular protrusion on the shaft and a fixed plate mounted in the housing perpendicular to the axis of the shaft with an inclination towards the front wall of the housing in such a way that at maximum approach to the protrusion on the shaft, their surfaces are parallel. The combination of these features provides a more affordable use of this device in everyday life, since the use is carried out without any additional mechanisms.

The presence of the protrusion located on the shaft of the rectangular splitting element allows you to determine the slope of the fixed plate installed in the device body, which is most suitable for cracking the pine nut shell.

Box 1.

The proposed device includes a splitting element, consisting of a shaft, a protrusion on the shaft and a fixed plate in the housing, which allows you to not use any additional devices, mechanisms and objects in the process of cracking a pine nut shell.

The proposed device may include at least one handle. Moreover, in cramped conditions, it is advisable to use a straight-shaped handle.

The presence of a splitting element, driven by physical impact on the handle, without outside help, and the absence of additional mechanisms and elements allows the invention to be used freely and affordably in domestic conditions.

Box 2.

The device includes a device casing, consisting of two walls, a rear and a front part of the device, a shaft on which protrusions, handles and a drive are located. On the back of the device, which is opposite the shaft with the protrusions, there is a plate for cracking the walnut shell, at an angle to the shaft in such a way that it would be parallel to the teeth in the places of greatest convergence (contact).

The invention is illustrated by the drawing, in which Fig. 1 shows a top view of a device for cracking a pine nutshell, in Fig. 2 is a side view, in Fig. 3 is a view of the back wall, in Fig. 4 is a top view, in Fig. 5 is a view from the side, in the figure No. 6 is a bottom view.

A device for cracking the shells of pine nuts consists of the following parts: a body in the form of a front wall 1, a rear wall 2, side walls 4, a shaft 3, a plate 5 for cracking a walnut shell. The protrusions are placed on the shaft 3. A part of the shaft 3 extending beyond the side wall 4 on the left side of the device is a drive 8, a part of the shaft 3 extending beyond the side wall 4 on the right side of the device is a handle 7. The distance above the shaft 3 between the front wall 1 and the nut shell cracking plate 5 is a loading hopper. The distance under the shaft 3 between the front wall 1 and the rear wall 2 is the receiving hopper.

A device for cracking a pine nut shell works as follows.

A nut or several nuts are poured into a receiving hopper located above the shaft 3 between the front wall 1 and the rear wall 2 (not shown in the figures). Nuts get stuck between the nut shell cracking plate 5 and the shaft 3. The rotation that is imparted to the shaft 3 due to the rotational movement of the drive 8 allows the projections 6 to crack the walnut shell on the nut shell cracking plate 5. Next, the pine nut in a cracked form enters the receiving hopper, located under the shaft 3 between the front wall 1 and the rear wall 2 (not shown in the figures).

The nut shell cracking plate 5 is installed in such a way that when approaching the projection 6 located on the shaft 3 as close as possible, their surfaces are parallel to each other (Figure 1a).

The use of the invention will allow, in comparison with the prototype, to increase the availability of the use of a device for cracking pine nuts in domestic conditions, since the use is carried out without any additional mechanisms.
