Abstract

The utility model relates to a semi-automatic thresher for rice and wheat, which is composed of a cover casing, a threshing roller, a main shaft, a blower, a supporting frame, a belt pulley, a sieve plate and a bagging machine. The utility model is characterized in that one side of the main shaft is orderly provided with the belt pulley and an eccentric head flange disc which is connected with the sieve plate through an eccentric connecting rod and a tripod, a discharge port of the sieve plate is connected with the bagging machine, and both sides of the threshing roller are respectively provided with an anti-winding device. The semi-automatic thresher for rice and wheat has the advantages of convenient maintenance and automatic bagging function without generating the phenomenon that the main shaft is wound by straws.

Description

Semi-automatic thresher for rice and wheat

The utility model relates to a kind of farm machinery, the semi-automatic thresher of particularly a kind of rice wheat.

Traditional rice-wheat thresher; its structure mainly is: by a driven by motor main shaft; threshing cylinder rotates; and be used with sieve plate; the grain of rice on the paddy rice bar is taken off in gear hobbing on the threshing cylinder; the main shaft of such rice-wheat thresher is a structural member with eccentric head; and eccentric head is a consumable accessory; damage must be changed eccentric head and main shaft together, is not easy to maintenance, in addition; there is not the anti-measure that twines on the thresher; straw often takes place and snarls the main shaft phenomenon in threshing course, and the part weeds enter the service life of reducing bearing in the bearing holder (housing, cover) have to shut down and work inefficiency again after weeding a garden.

The purpose of this utility model provides a kind of maintenance of being convenient to, and can improve machine service life, reduces labor intensity and saves the semi-automatic thresher of labour rice wheat.

The utility model is achieved in that the semi-automatic thresher of this rice wheat is mainly by the case threshing cylinder; main shaft; fan blower; bearing support; belt pulley; sieve plate and sack filling machine are formed; main shaft passes through two bearing fixing on bearing support; be characterized in a belt pulley being installed at an end of main shaft; between belt pulley and thresher drum; an anti-winding device is installed respectively between threshing cylinder and the fan blower; on main shaft, an eccentric head flange dish is installed in the outside of belt pulley, and this off-centre head flange dish passes through eccentric ratio; tripod is connected with sieve plate, and the discharging opening and the sack filling machine of sieve plate join.

The utility model and installed anti-winding device in the both sides of threshing cylinder because eccentric head flange dish is connected with main shaft spiral shell mosquito, thus easy to maintenance, stopped the phenomenon that straw snarls main shaft, the utility model still has the function of automatic bagging.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of the semi-automatic thresher of rice wheat.

Fig. 2 is the front view of eccentric head flange dish.

Fig. 3 is the right view of Fig. 2.

Fig. 4 is the front view of tripod.

Fig. 5 is the right view of Fig. 4.

Fig. 6 is the front view of eccentric ratio.

Fig. 7 is the anti-front view that twines cover plate.

Shown in 1-7, this rice wheat automatic thresher comprises: tripod 1, eccentric ratio 2, eccentric head flange dish 3, belt pulley 4, threshing cylinder 5, case 9, bearing support 10, fan blower 11, anti-cover plate 12, main shaft 13, anti-bar 15 and the sieve plate 16 of twining of twining; Threshing cylinder 5 and main shaft 13 coaxial installations; threshing cylinder 5 is by cylinder flange 6; roller shelves 7 and the threshing tooth 8 that is inserted on the roller shelves 7 are formed; main shaft 13 is installed on the support 10 by two bearings 14; left end at main shaft 13 is installed belt pulley 4 successively; eccentric head flange dish 3; wherein rice-wheat thresher employing motor is a power source; motor is connected eccentric head flange dish 3 and is connected with the upper end of eccentric ratio 2 with belt pulley 4 belts; the lower end of eccentric ratio 2 is connected with sieve plate 16 high order ends by tripod 1; the vibration of sieve plate 16 is driven by motor belt pulleys 4; eccentric head flange dish 3 rotates; eccentric head flange dish 3 drives eccentric ratios 2 and moves up and down and realize; on the main shaft 13; prevent twining backplate 12 and prevent twining the both sides that bar 15 is installed in threshing cylinder 5 respectively; it can prevent effectively that straw is entangled on the main shaft 13; right-hand drum blower fan 11 at threshing cylinder 4 is fixed on the bearing support; the effect of this fan blower 11 is that the cutted straw that will hit down blows out outside the machine; during threshing; threshing cylinder 5 is around main shaft 13 rotations; paddy rice or wheat and threshing tooth 8 bump against; take off the grain of rice in the machine and fall on sieve plate 16; fan blower 11 blows out the cutted straw end and wants outside the machine; the eccentric head flange dish 3 of rice wheat automatic thresher left end is by eccentric ratio 2; tripod 1 drives sieve plate 16 vibrations; the rice wheat that is sent to sieve plate 16 ports of export enters sack filling machine 16, packs.

Claims
