Described rubber peel is fixed on shaker basket edge by rubber peel press strip.
The beneficial effects of the utility model are：
The utility model is using tail sheet combined system during shaker vibration, and longitudinally vibrations can be prevented effectively tail sheet
Grain is spilt, and is carried out repeating to screen out, is improved sieve grain efficiency.
Brief description of the drawings
Fig. 1 is the utility model overall structure figure.
Fig. 2 is sieve structure chart under the utility model rice machine.
Fig. 3 is the utility model tail sheet structure chart.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As described in Fig. 1-3, tail sheet combined system sieve, tail sheet and shaker basket under rice machine are constituted, described tail sheet
It is made up of the tail sheet zigzag sieve of the fixed counterpiece number of some tail sheet bars series connection simultaneously, and in tail sheet fixed plate, one
As connected simultaneously using 6 tail sheet bars fix 29 numbers tail sheet zigzag sieve it is preferred, tail sheet fixed plate by bolt,
Plain cushion and spring washer are fixed on sieve under the end of shaker basket, rice machine and are fixed on shaker basket by bolt, plain cushion and spring washer
Bottom surface；Vibratory sieve transmission system is successively by semicircle balance weight iron, vibratory sieve sprocket wheel, vibrating screen bearing seat, fixed seat and bias
Wheel is connected to one end of drive link, and the other end that eccentric wheel, bearing block and bearing block are sequentially connected drive link is fixed on tail sheet group
In shaker basket below syzygy system.Described bolt connects split pin by plain cushion, spring washer and fixes screening bar.Also include material
Driver plate, material driver plate, which is fixed on the head end of shaker basket, material driver plate, is evenly arranged with horizontal convex bar.Also wrap
Rubber dermatotome after main horizontal screw conveyor is included, obliquely under rice machine below the junction of sieve and tail sheet.Described material
The installation direction of driver plate is tilted to screening bar combined system.The installation direction of described tail sheet inclines to screening bar combined system
Tiltedly.Described material driver plate, one end is fixedly connected on the head end of shaker basket, and one end is overlapped on the shelves below material driver plate
