4 cl, 5 dwg

The invention relates to presses-extruders and can be used in the manufacture of briquettes for fuel and peat pots for seedlings.

Known press-extruder for producing briquettes from lignite (http://www.ukrstroydom.com/index).

It is designed for processing (sintering) waste coal and peat.

Using the media can be processed anthracite stiby, coal slurries, powder brown coal and peat.

The finished product has the form of cylindrical rods with a diameter of 30...40 mm and a length of 50...200 mm, consists of a frame, mounted on it, the press-extruder with a nozzle, a gearbox with an electric motor to drive the screw of the extruder.

The disadvantage of this press-extruder is that the finished product, having a view of a cylindrical shape, there is no holes for better combustion in the furnace, and this press-extruder, it is impossible to produce peat pots for seedlings.

Also known screw press PSN 06.00.000 development LLC "Technical center" merovigian, intended for the manufacture of briquettes cylindrical shape with an inner bore for better combustion of the briquettes in the oven.

Consists of a frame with brackets for attachment to the tractor, mounted on her extruder with hopper for loading the process material, the neka variable pitch coils, on the output shaft of which is mounted the screw terminal with the rod that is installed in the nozzle cone drive mechanism with a safety clutch and gearbox.

The disadvantage of this screw press is that it is not possible to produce peat pots for seedlings.

The purpose of the invention is to expand the technological capabilities of the press-extruder - manufacture of peat pots for seedlings.

This goal is achieved by the fact that the nozzle is tapered from the butt hinged flap, cyclically overlapping its plane of outlet nozzles cone and rod end of the screw does not reach the plane of the flaps in overlapped condition of the outlet nozzle cone on the "a"value, equal to the thickness of the bottom of the peat pot, and the flap has a drive device for adjustment of the cycle of rotation.

The contour of the flap executed on a curve such as a circle, and has a recess around the perimeter. Under the nozzle cone in place out of the peat pot is set a tray with two symmetrical sloped surfaces on an algebraic curve of the 3rd order:

X³=y²(D-x),

Cissoid of Diocles with a given diameter "D"equal to the outside diameter of the peat pot;

and "x" and "y" coordinates of Cissoid of Diocles.

The tray is fixed to the body nasadq the cone with the possibility to adjust its position.

Thus, the inventive press-extruder for the manufacture of peat pots meets the criterion of "Novelty."

The features distinguishing the claimed technical solution to the prototype, in other technical solutions in this field of technology have been identified that leads to the conclusion that the inventive press-extruder for the manufacture of peat pots meets the criterion of "substantial differences".

Figure 1 shows the proposed press-extruder for the manufacture of peat pots, side view; figure 2 - nozzle cone, side view, the position overlapped with the opening of the nozzle cone; figure 3 - nozzle cone side view, position when the open hole of the nozzle cone; figure 4 is a end view on the nozzle cone, tray and peat pot, the position of the tray unloading peat pots on the left side; figure 5 is a end view on the nozzle cone, on the tray and peat pot, the position of the tray unloading peat pots on the right side.

Press-extruder for the manufacture of peat pots contains a frame 1 with brackets 2 for attachment to the tractor, mounted on the frame 1 of the extruder 3 with the hopper 4 to load the process material, such as peat, the screw 5 with a variable step turns on the output shaft of which is mounted screw terminal 6 with the rod 7 mounted in the nozzle of conyn the th 8, the drive mechanism 9 with the friction clutch 10 and the gear 11.

The nozzle cone 8 with the end of the hinged flap 12, cyclically overlapping its plane of outlet nozzles cone 8 and the shaft 7 of the screw terminal 6 does not reach the plane of the flap 12 in blocked condition of the outlet nozzle cone 8 on the "a"value, equal to the thickness of the bottom of the peat pot 13, and the valve 12 has an actuator 14 with a device 15 for adjustment of the cycle of rotation.

The contour of the flap 12 is executed on a curve such as a circle, and has a recess around the perimeter. Under the nozzle cone 8 in place out of the peat pot 13 is installed, the tray 16 with two symmetrical sloped surfaces 17, made by an algebraic curve of the 3rd order:

X³=y²(D-x),

Cissoid of Diocles with a given diameter "D"equal to the outside diameter of the peat pot 13;

and "x" and "y" coordinates of Cissoid of Diocles.

The tray 16 is fixed on the body of the nozzle cone 8 with the possibility to adjust its position.

For press extruder using brackets 2 which are welded to the frame 1, to hang it on the tractor.

When turning on the PTO (PTO) of the tractor through a drive mechanism 9, the safety clutch 10 and the gear 11 is driven into rotation of the screw 5 with variable step Vit is s, on the output shaft of which is mounted screw terminal 6 with the rod 7, which will also rotate in the nozzle cone 8. From the drive mechanism 9 is engaged and the actuator 14, which through the device 15 adjustment of the cycle of rotation causes the valve 12.

When entering the hopper 4 technological material, such as peat, extruder 3 starts to work. Auger 5 variable pitch coils to condense the process material, such as peat, and send it to the nozzle cone 8 to the screw terminal 6 with the rod 7.

When blocked by a valve 12 opening of the nozzle cone 8, the space between the flap 12 and the rod 7 is filled with technological material, such as peat, and is formed in the bottom of the peat pot 13 (figure 2).

When the open hole of the nozzle cone 8 compacted technological material, such as peat, extruded through a hole of the nozzle cone 8 to the outside (figure 3) until such time as the valve 12 is again not block the hole of the nozzle cone 8.

Due to the fact that the contour of the valve 12 is executed on a curve such as a circle, and has a recess around the perimeter, then the overlap of the nozzle orifice cone 8 valve 12 will separate the peat pot 13 from the continuous flow of process material, such as peat coming through the hole of the nozzle cone 8. Then the cycle repeats.

To exclude the destruct the Oia peat pot 13 in the fall to the ground under the nozzle cone 8 in place out of the peat pot 13 is installed, the tray 16 with two symmetrical sloped surfaces 17, performed on an algebraic curve of the 3rd order:

X³=y²(D-x),

Cissoid of Diocles with a given diameter "D"equal to the outside diameter of the peat pot 13;

and "x" and "y" coordinates of Cissoid of Diocles.

The tray 16 is fixed on the body of the nozzle cone 8 with the possibility to adjust its position.

The application of the proposed press-extruder for the manufacture of peat pots will expand the technological capabilities of the latter, will allow efficient production of peat pots for seedlings.
