Description

 The invention relates to agricultural machinery and can be used to highlight seeds of gourds, in particular watermelon.

 The selection of seeds of gourds is carried out on the grinder IBK-5A.

 It is also known seed device, including a receiving hopper, grinding and wiping drums, concave.

 However, it is complex in design, cumbersome, and is used mainly in lines for the isolation of melon seeds. And the necessary simpler, mobile device, which is especially needed by farmers, cooperatives, rental groups.

 In FIG. 1 shows a seed extractor of gourds, front view; in FIG. 2 same side view.

 The separator consists of a receiving hopper 1, shaft 2, located immediately in two zones: grinding I and wiping II. Grinding and wiping gear elements 3 in the form of rounded fingers are radially mounted on the shaft along the entire length. They are placed along a helical line, and in the grinding zone I, the installation step is greater than in the rubbing zone II. In the grinding zone, the upper deck 4 is installed.

 The upper deck is made of plates (perpendicular to the shaft) (round). The lower deck is installed along the entire length of the shaft and is a cylindrical removable sieve 5. Depending on the processed fruit, the diameter of the holes of the sieves changes. In the grinding zone, the sieve is reinforced and more durable. The equipment is placed in the casing 6. At the level of the lower deck in the end part there is a window 7 for the exit of seeds. Under the sieve there is a pallet 8 for collecting pulp, juice (pulp). From the pallet, all this can be pumped to any capacity. If necessary, the separator is equipped with a shower device. All nodes are mounted on the bed 9. The shaft is driven from the electric motor under stationary conditions or from the tractor PTO in the field on which the seed separator is mounted.

 Isolator seeds of gourds works as follows.

 The fruits are manually fed into the receiving hopper 1, where they roll, fall under the action of the teeth 3 passing between the plates of the deck 4. When the drum rotates, the fruits are crushed and the entire mass passes through the cracks between the plates. The plates have a curved shape. After entering the lower deck, additional crushing of the bark occurs and the process of separation of seeds begins. The installation of the teeth along the helix provides mixing of the crushed material to the side. In the process of displacement, there is separation of seeds and pushing, centrifuged feeding through the holes in the sieve of crushed bark, juice and pulp. They fall into the pallet 8. In order to intensify this process, the installation step of the teeth 3 in the zone I wiping is reduced. There is a complete selection of seeds and mixing to the window 7, through which they fall into the container and delivered to the place of drying and, if necessary, further refinement.

 The ends of the teeth are rounded, rubber-fabric covers can be worn on them. All this ensures the allocation of seeds without injuring them. In addition, the gap between the teeth and the lower deck is adjustable. The rotational speed of the drum shaft is also adjustable.

A check on the fruits of watermelon showed that the device performs its functions and practically releases seeds. This is because the separation process is single-stage. In existing designs, part of the seeds go away with the pulp and peel. Seed purity is also high up to 96% Laboratory germination of freshly isolated seeds 100%
The gourd seed isolator is simple in design, single-stage, not bulky. It eliminates the loss of seeds and ensures their high purity.
