On the sides of the necks of funnels are welded to both longitudinal docking station (corners 20×20 mm). Then do a cut, otherwise it will be impossible to remove each drum separately, replacement straps and maintenance of the mill. Exposed frame dock hopper symmetrically on the corners, marked the location and drilled the holes for the threaded M8, which should match the axes. Bolts to attach the hopper to
the neck should pass through a rubber gasket (old inner tube). Grover washers are installed from the bottom.
Further, from the area 65×65 mm cooking the base of the mill. Join the rack, and the top — gathered front of this design. From tubes of diameter 21×1,5 mm made braces.
The sub frame is mounted in the frame hinge. For belt tension is adjustable stop out of the corner of 50×50 mm that is fixed to the desired mark two locks. The area is clamped with two bolts M16 with a fluted head.
Springs keep constipation when working mill, and also press the pin to recess with open locks. Adjustment system (height) edge of the sub-frame greatly simplifies the possibility of using different power transmission belts. Besides, as stressed above, enables easy starting of the motor by relaxing the straps, which are at the bottom right of the engine it is necessary to weld a simple, but reliable and convenient device in the form of telescopically dvigaysya pipes. Put long handle-pipe will make it easier to hoist sub-frame with motor.
The clamp device screw fixing adjustable stop Assembly:
1 — base; 2 — strut; 3 — a guide welded (steel area 50×32 with a longitudinal window 400×18); 4 — focus adjustable; 5 risks; 6 — over-time-pin (ST5, d10, L100) with a disc-shaped head; 7 bolt M18 modified; 8 — spring; 9 — bracket is welded (steel area 45×45, L170, window 110×19); 10 — M18 nut with extended washer, 2 sets.); 11 — frame sub; 12 — brace war Noi; 13 — M16 screw with knurled head; 14 — spacer extended; 15 – M16 weld nut with washer; 16 — pin with spring.
The crushing head shaft is machined from steel ST5. Double-strand pulley is mounted on it pin M8 under the screwdriver and contra nuts with washer Grover. Pins for two. At their ends they go into the notches on the shaft and rigidly fixed parts.
Now you need to accurately measure the height from the sole of the buildings to the corresponding crossmember on which they are installed. To eliminate gaps, you can apply temporary blocks of wood. According to the size of the regrind is U-shaped insert of channel 50×30 mm. In them it is necessary to drill holes for bolts M14 for fastening of enclosures, ensuring that the latter were perpendicular to the frame and parallel to each other. Then set the hull on the prepared places for them and reassemble the mill. Strictly to adjust the shaft axis of the drums and weld the modified U-shaped insert to the cross members of the frame of the crushing site.
After installation and verify that the shaft need to install the rails between the soles of the buildings and the U-shaped toe, on which they are mounted. This can be done in a 5 mm drill, perform two holes of appropriate. To fully appreciate such a “trifle” will fail when disassembling and assembling the mill, when replacing belts, bearings and other transactions on homemade equipment.
Right crushing head:
1 — shaft with the driven double-strand pulley (ST5); 2 — bearing 1608, self-centering (from discarded farm equipment); 3,8 — bushing spacer (STZ); 4 — lid of the drum (2); 5 — coil (STZ, 2); 6 — segment shock (from the decommissioned agricultural equipment or homemade, ST5, s2…4, 54); 7 sleeve remote (STZ, 54 pieces); 9 — nut M39 right (on the left head — spruce thread); 10—disk sorting (MFIs); 11 —axis of the shock segments (ST5, 4 pieces); 12 — washer (4 PCs); 13 —cotter pin (4 PCs.).
Coils crushing the heads must be machined with one setup in a lathe. With great precision it is necessary to make a layout and drill holes for axles with a diameter of 20 mm.
The axis — serial DKU or homemade. The holes for the cotter pin to release the axle, drilled a 3 mm pobeditovym a drill. The cotter pins from the annealed 3 mm steel wire.
The shock segments, it is desirable to have a serial (DKU, sets the thickness of 2-4 mm). The greatest burden falls on the first series of segments from the supply of raw materials, they are the “fast” and more wear. Thin segments is also short-lived, but give quality flour. I, for example, scored sets, where the first segments 4 mm thick, and the rest by 2 mm When the wear on one working side segments of the coil is recommended to swap, and “actuated” segments to turn.
The protective cover of the drum when changing the sorting of the disk is removed very easily
Not a problem and reinstallation and impact on the crushing head
A spacer on the shaft, it is advisable to do the latter, when the whole mill is almost assembled. It is necessary for the correct installation of the coils so that the gaps from the axis to the rear of the drum walls was about 1 mm, such as from sorting disks.
The disks are nested in the respective covers, which are available with bead welded 4-mm “wire rod” pribavlyaetsya and securely fixed at the edge of the drums. The caps themselves are fastened by screws M14 located on the forks of the yokes.
The outlet pipes homemade. Downstairs they have a piping weld “rod” to avoid slipping bag. And for the convenience of mounting and quick removal of the containers provided by the spring.
In the electrical equipment of the mill necessarily includes magnetic contactor. Also required current relays, repair switch with visible break the chain, an ammeter. In short, everything to work at the mill was safe.
