Machine for separation of seeds from the fruit melons

 

(57) Abstract:

The invention relates to agricultural machinery, in particular to machines for cutting fruits with the Department of seed and can be used in agriculture and fruit processing industry. The surface profile conveyors, produce seeds, has a configuration corresponding to the profile of the fruit. The working elements of the upper spring-loaded conveyor mounted on the shaft of the string reels with two disks, one of which is stationary and the other can move along the axis. And string reels hooks are conducive to capture pieces. The lower mesh conveyor moving at a slower speed than the upper, and their direction opposite that allows you to improve the quality of selection by increasing the time of exposure to the selector to pieces without changing the dimensions of the machine. 3 C. p.

The invention relates to agricultural machinery, in particular to machines for cutting fruits with separation of seeds, and can be used in agriculture and fruit processing industry.

A known machine for this selection is shaped brush for separating seeds cleaning device and the actuator [1]

The disadvantage of this machine is that all the brush work body cannot copy non-spherical surface and not fully allocates the seeds from the fruit halves nonspherical shapes and sizes. In addition, the brushes have a shock effect on the seeds, which leads to their damage and reduce the useful germination.

The closest technical solution and the achieved result is a machine for separation of seeds from the fruit melons [2] In this machine the fruit is fed into the hopper, cut into pieces a knife bars, oscillating around an axis, the pieces are then routed between the upper movable conveyor and the lower sieve. Under the sieve is installed fixture for removal of seeds, made in the form of a tray and rumble with the pallet for removal of the separated seeds. For better separation of pile machine has a per capita device.

The disadvantage of this machine is the clogging of the holes on the bottom of the sieve, which dramatically reduces the productivity and quality branch of the seeds of the pieces. In addition, the need for chopping fruit to pieces close to flat form.

Zenjshina energy consumption for shredding of fruit due to more large pieces. Constructive implementation of the elements of the proposed machine allows the allocation process the seed continuously and to create conditions that exclude impact on the seed.

This is achieved by the fact that in the car for the selection of seeds containing hopper grinder (not shown), pitched the Board with the guides, a device for the selection of seeds, made in the form of two mounted one above the other movable conveyors with adjustable gaps at the input and output, decreasing in the direction of movement of the fruit. The inclined upper and lower horizontal mesh conveyors have a specific configuration of the working surface, allowing you to copy different profiles pieces. Moreover, the spring-loaded upper conveyor working surface is formed by three string reel mounted on each shaft. The working surface of the string has hooks for better grip piece. String reels mounted on the shaft and each of them have two disks, one of which is stationary and the other is able to move along the axis offset is limited to retaining rings. This design allows the drum proposalcentral the profile of the lower horizontal conveyor, that allows you to evenly cover the entire surface of the piece. This contributes to the complete separation of the seeds from the pulp.

In Fig. 1 shows a diagram of the proposed machine (top view), and Fig.2 a longitudinal section a-a in Fig.1; Fig.3 cross-section B-B section b-In Fig.2; Fig.4 device strings drums; Fig.5 type G in Fig.2.

Machine for separation of seeds from the fruit melons contains shredder, drives the conveyor 11 (Fig.1) pitched the Board 1 with the guides 9, the device for separation of seeds from pieces made in the form of two mounted one above the other movable conveyors specific configuration of the working surface. The profile of the upper inclined conveyor 3, respectively repeats the profile of the lower horizontal mesh conveyor with 6 dividers 7. Under the working branch of the lower mesh conveyor 6 is mounted tray for collecting seeds 5, and at the end of the hopper drive 4 pieces.

Machine for the selection of seeds is as follows. Fruits, shredded into large pieces (the fruit is divided into 4-6 pieces), served on a solid Board 1 on the lower horizontal mesh conveyor 6. Guides 9 on the sloped Board evenly distribute the weight of the ro according to the thickness of the pieces. This prevents scrivanie before conveyors and provides a secure grip pieces of string reel 2 upper spring carrier.

The working surface of the upper 3 and lower conveyors are moving in different directions with different speeds, and the speed of the lower conveyor considerably less top speed. This increases the exposure time of the working bodies of the selector into pieces and contributes to a particular orientation of the pieces on the lower conveyor 6. Brush 8 is fixed on the lower movable conveyor, eliminate clogging the cells and make them clean and ensure the continuity of the technological process.

The upper conveyor 3 hooks strings drums captures pieces and dragging them along the bottom horizontal mesh conveyor, moving towards the progress of the piece at a slower speed, separates seeds method abrasion. The separation of the seeds contributes to decreasing the gap from the beginning of the conveyors to their end. The separated seeds through the holes of the conveyor 6 into the tray 5. Peeled pieces of the fruit of the upper conveyor 3 are fed into the storage hopper.

1. MACHINE FOR separation of SEEDS FROM the FRUIT of MELONS,which is inclined to the lower horizontal characterized in that the conveyors are made so that they formed the gap has a profile corresponding to the profile of the segments of the fruit.

2. Machine under item 1, characterized in that the upper conveyor is spring-loaded and consists of three mounted on a shaft string reels, one of the ends of each drum mounted on the shaft firmly, and the other is free.

3. Machine for PP. 1 and 2, characterized in that the strings drums are hooks to capture slices of fruit.

4. Machine for PP. 1 to 3, characterized in that the lower conveyor mounted to move with less speed than the upper, with the direction of movement of the opposite.
