Abstract

The utility model discloses a thresher for rice and wheat, composed of a machine frame, a power device, a machine cover, a sieve plate, a roller, hobbings in spiral arrangement on the roller, a big side pole on one end of the roller near the power machine, a big check ring fixed on the machine frame and sheathed outside the big side pole, a small side plate, and a small check cylinder fixed on the machine frame and extending into the roller. The periphery of the small side plate is connected with the inner wall of the roller. The small side plate is arranged on one end of the roller away from the power machine. The thresher for rice and wheat can make weeds entering the thresher be pushed to the side away from the power device under the action of the hobbings to automatically remove the weeds form a weed outlet, and the big and the small check rings can efficiently prevent rice and wheat straws from winding a roller shaft. The thresher for rice and wheat has the advantages of convenient operation and labor saving.

Description

Rice-wheat thresher

The utility model relates to a kind of thresher machine, particularly a kind of rice-wheat thresher with rotation working part.

Rice-wheat thresher is the most frequently used agricultural machinery, and people have made many innovation and creation in this respect in recent years, to energy savings, reduces labor intensity, and aspects such as convenient use have played very big effect.Particularly No. 29 disclosed notification numbers of " Chinese patent communique " mat woven of fine bamboo strips 9 volume be CN2138387y " rice-wheat thresher ", reduce the wheat loss effectively by loam cake is set, push away blade and straw outlet by setting and help removing weeds in the machine of entering.Blade is consistent with the drum movement direction can't to be made weeds in the machine of entering be transported to an end to dispose, can't weed a garden automatically in fact but this thresher is because of pushing away; Though and be used in a way of last encapsulation letter and reduced the rice straw and be entangled in phenomenon on the axle, because of sleeve and side sheet room still have certain distance can't solve the problem that the rice straw twines axle fully.

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provides a kind of and can remove the weeds in the machine of entering automatically and thoroughly solve the thresher that the rice straw twines the drum shaft problem.

The purpose of this utility model is achieved in that a kind of by frame 1, actuating unit 2, cover 3 and away from the straw outlet 9 of a side of actuating unit 2, cylinder 4 and on gear hobbing 6 and roller bearing 5, the rice-wheat thresher that sieve plate 10 below the cylinder 4 is formed, it is characterized in that, gear hobbing 6 on cylinder 4 in the shape of a spiral shape arrange, make weeds in the machine of entering under the effect of gear hobbing 6 to being got rid of automatically from straw outlet 9 away from an end motion of actuating unit 2; One end of the nearly actuating unit 2 of cylinder 4 has a big side plate 7, prevents that big back-up ring 11 that rice and wheat straw twines roller bearing 5 is enclosed within on the big side plate 7 and is fixed on the frame 1; There are a periphery and the little side plate 8 that this inner wall of rotary drum links in an end inside away from actuating unit 2 of cylinder 4, and is fixed with a rice wheat straw bar that prevents that stretches into cylinder 4 on the side away from actuating unit 2 of frame 1 and twines the little back-up ring 12 of roller bearing 5; The size of big back-up ring 11 and little back-up ring 12 and width can effectively prevent also that with the operation that does not influence cylinder 4 rice wheat straw bar from twining roller bearing 5 and being advisable.

Compared with prior art and since gear hobbing of the present utility model on cylinder in the shape of a spiral shape arrange, can make be pushed to straw outlet under the effect of the gear hobbing that weeds in the machine of entering can be at the volley and automatically row get rid of; The side plate at cylinder two ends and back-up ring can prevent effectively that rice wheat straw bar is wrapped on the roller bearing, and be not only extremely easy to use, also can improve work efficiency greatly, can reach goal of the invention fully.

The utility model also can be described further in conjunction with the accompanying drawings.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is its A-A view.

Embodiment of the present utility model as depicted in figs. 1 and 2, by frame 1, actuating unit 2, cover 3, drum shaft 5, cylinder 4 and on the shape gear hobbing 6 of arranging in the shape of a spiral, the big side plate 7 of the nearly actuating unit end of cylinder 4 and be enclosed within that it is outer and be fixed on big back-up ring 11 on the frame 1; Straw outlet 9 on sieve plate 10 under the cylinder 4, cover 3 sides; Cylinder 4 inner and little side plate 8 that periphery links to each other with inner wall of rotary drum and be fixed on on the side frame and stretch into little back-up rings 12 compositions in the cylinder 4 away from an end of actuating unit 2; The size of size back-up ring and width can effectively prevent also that with the operation that does not influence cylinder 4 rice wheat straw bar from twining drum shaft 5 and being advisable.Enter at work to be pushed to away from an end of actuating unit 2 under the effect of the spiral gear hobbing 6 that weeds in the machine can be at the volley and get rid of automatically from straw outlet 9, big side plate 7 and big back-up ring 11, little back-up ring 12 can prevent effectively that rice wheat straw bar from twining drum shaft 5, easy to use, laborsaving and efficient height.
