Description

 The invention relates to agricultural machinery and can be used in the food industry for processing fruits of melons, in particular pumpkins.

 A known machine for the selection of seeds from the fruits of melons, the closest in essence and in the number of common essential features, including a frame, drive, loading hopper, knife and locking mechanism, the latter is made in the form of two conveyors mounted on top of each other with a gap decreasing in the direction of movement of the fruits, and the working branch of the upper conveyor is spring-loaded, and the lower conveyor is rod-shaped, and under its upper branch the full width of the water supply unit is installed, made in the form of a slot nozzles (SU, copyright certificate 1708258, class A 23 N 4/12. Machine for isolating seeds from the fruits of melons / Tseplyaev AN, Shaprov MN, Boromensky VP Declared December 19, 1989; published January 30, 1989 .1992). This machine for the selection of seeds from the fruits of gourds we took for the closest analogue.

 The disadvantage of this machine is the inability to control the volume of water supplied during the processing of fruits of various sizes. Because of this, with a constant volume of water supplied to the processed halves of fruits with smaller sizes, their inner cavity is filled with water. Water does not have time to pour out under its own weight along with the allocated seeds from the fetal cavity. This makes further seed isolation difficult. This is due to the fact that the action of the leaching jet on the spermatic cords is suppressed by the accumulated mass of water inside the fetus.

 The invention consists in the following.

 The task to which the invention is directed is to improve the quality of seed extraction from pumpkin fruits.

 The technical result is a reduction in labor costs and improving the quality of the process of seed allocation and productivity.

 The specified technical result is achieved by the fact that in the known machine for separating seeds from the fruits of melons, including a frame, a drive, a loading hopper, a knife with a guiding device, a locking mechanism and a water supply unit, according to the invention, a mechanism is installed in each water supply pipe to the nozzle water flow control, while the mechanism is connected by a system of levers with a copy roller mounted on the upper conveyor.

 The invention is illustrated by drawings.

 Figure 1 schematically shows a seed separator, side view.

 Figure 2 is a section aa in figure 1.

 Information confirming the possibility of implementing the proposed technical solution are as follows.

 The separator of seeds from pumpkin fruits (see figures 1 and 2) includes a frame 1, a drive 2 in the form of an electric motor, a coupling and a reducer, a loading hopper 3, a knife 4 with a guiding device 5, a locking mechanism made in the form of two mounted one above the other conveyors: the lower rod conveyor 6 and the upper conveyor 7. The working branch of the conveyor 7 is spring-loaded due to the copying rollers 8. The water supply unit contains two slotted nozzles 9, which are separated for ease of regulation of water flow. The nozzles 9 are connected to the water supply pipe 10 and installed under the upper branch of the lower conveyor 6. A tray 11 and a tray 12 for collecting seeds are installed for removing seeds. In each water supply pipe 10, a water flow control valve 13 is installed, which is connected by a system of levers 14 to the copying roller 8 of the conveyor 7 (see Fig. 2).

 The seed separator works as follows.

 Fruits intended for processing are served in the loading hopper 3 either manually or by conveyor. Then they are cut with a knife 4 into two halves. The fruit halves are guided by the guiding device 5 and are oriented downward by the cutting plane and placed on the lower conveyor 6. As a special case, the fruit halves can be asymmetric. This leads to the fact that on the lower conveyor 6 will move different sized halves of the fruit.

 The endless belt of the upper conveyor 7 under the influence of the copying rollers 8 compresses the halves of the fruit, copying their macro-surface. This design allows you to fix on the lower conveyor 6 several halves at once, regardless of their shape and size. The working branches of the upper and lower conveyors 7, 6 move in the same direction. This ensures reliable fixation of the halves and prevents their accumulation in front of conveyors 6 and 7.

 Under the working branch of the conveyor 6, two slotted nozzles 9 are installed. A pumping unit (not shown in the drawings) through pipelines 10 is supplied with water under pressure. If there are no halves of fruit on the conveyor 6, then the water flow control valves 13 shut off the water supply to the crevice nozzles 9. When each half moves along the conveyor 6, the copying roller 8 rises and opens the control valve 13 by an appropriate amount through the system of levers 14. The water entering the half manages to merge during this time and does not complicate the allocation of seeds.

 While processing halves of different sizes, the big half raises the copy roller 8 above and through the system of levers 14, acting on the stem of the valve 13 controlling the flow of water, increases its flow area. This thereby increases the flow rate of water only in that nozzle that releases seeds from a larger half of the fruit.

 Each of the nozzles 9 forms a flat stream equal to half the width of the lower conveyor 6. Water passing through the working branch interacts with the placenta of the fetus and flushes seeds from it only in that half of the fetus under which it is located.

 The separated seeds, together with water, flow down the tray 11 into the tray 12 and are discharged for further processing and drying. Halves of fruit without seeds, conveyor 6 are fed into the storage hopper (not shown in the drawings) for further processing.

 The use of this machine allows you to select seeds without shock and damage from the pumpkin fruit of any shape and size. The pulp of the fetus is stored for further processing for food purposes or feed to farm animals.
