Abstract

FIELD: agriculture. SUBSTANCE: machine has a hopper and devices for destruction of fruit and removal of seeds. The devices are located in the hopper. The device for destruction of fruit is a disk rotor. At least three stem-shaped members are secured in the disk center at equal distances from each other. The members are inclined relative to the rotation axle. A ring-shaped member joins together the upper ends of the members. EFFECT: higher efficiency. 1 dwg

Description

 The invention relates to agriculture and can be used in seed production and food industry.

 A device is known (ed. St. N 600999, 1980) for separating seeds from pome fruits containing a crusher, feeder and filter rotor, inside which a cone is mounted, rigidly connected to the rotor, while the lower part of the cone has longitudinal slots located obliquely with the generatrix cone, and the upper part of the cone is made with a flange for the descent of the pulp.

 In this device, a high percentage of damage to the seeds, since the grinding of fruits occurs by a crusher inside the cone by abrasion.

 The closest in technical essence to the achieved effect is a machine for extracting seeds from the fruits of melons, containing a hopper and devices for destroying the fruits located in it, made in the form of a polyhedron, each face of which is equipped with knives, the polyhedron is shifted to the bottom wall of the hopper, and in last made pockets for the passage of knives, and a device for separating seeds from the chopped heap, made in the form of a drum with grooved scourges.

 The disadvantage of this machine is that some of the seeds are damaged by knives during grinding and corrugated whips when the seeds are separated from the heap.

 The technical problem solved by the invention is to increase the yield of intact seeds.

 This problem is solved in that the device for destroying fruits is made in the form of a disk rotor, in the center of which at least three rod elements are fixed at an equal distance from each other and with an inclination from the axis of rotation, at which the upper ends are connected by an annular element. The essence of the invention lies in the fact that the increase in the yield of intact seeds is ensured by the fact that the fetus is fixed in the center of the disk rotor between the three core elements and is destroyed by centrifugal forces.

 With the destruction of the fetus from the action of centrifugal forces, the seeds are separated from the pulp, which makes it possible to isolate the seeds from the chopped heap without the use of water, to reduce the energy consumption for the destruction of the fetus.

 Technical solutions are known (see ed. St. USSR 738588, class A 23 N 1/02), in which a rotor is used, inside which a cone is mounted rigidly connected to the rotor, however, the proposed machine uses a disk rotor in the center of which centering and fixing the fetus is fixed at an equal distance from each other at least three core elements, the upper ends of which are connected by an annular element. Such a combination of essential features in the device for isolating seeds is unknown, which is confirmed by a patent search. Thus, in this case, the known elements, combined with new bonds, give the object a new property, manifested in a positive effect, an increase in the yield of intact seeds, as a result of which the solution can be recognized as having an inventive step.

 The drawing shows a machine for the selection of seeds from the fruits of melons, side view.

 A machine for extracting seeds from fruits of melons and gourds contains a hopper 1, in which there is a device for destroying fruits and isolating seeds, made in the form of a disk rotor 2, in the center of which for centering and fixing the fruit are fixed at an equal distance from each other and inclined from the axis of rotation three rod elements 3, the upper ends of which are connected by an annular element 4. The number of rod elements may be more than three. An increase in the number of core elements of more than 6 leads to a larger grinding of the fetus, which worsens the allocation of seeds. At the outlet of the hopper, a screen 5 for a pile of destroyed fruits and a screen 6 for selected seeds, driven by a drive 7, are installed to swing. To collect juice, a tray 8 is installed at the bottom of the screen 6.

 The device operates as follows. Fruits are sent individually to the hopper 1 and fall through the annular element 4 and fixed between the three rod elements 3 in the center of the disk rotor 2, which is driven by the drive 7. In this case, centrifugal forces act on the fetus, which at a certain speed of rotation destroy the fetus into pieces. The decay of the fetus is accompanied by the release of seeds from the pulp. Due to the rotation of the disk rotor, the crushed heap is thrown onto the swinging screen 5 and is divided into crusts with pulp and seeds that fall on the screen 6, where they are freed from small pulp. Juice from the destroyed fruit is collected in tray 8.

 Thus, the use of the proposed machine for the selection of seeds from the fruits of melons can give a significant economic effect by increasing the yield of intact seeds.
