Abstract

The utility model relates to a cam vibrating-screen thrasher, which provides a small power thrasher with the advantages of simple structure, light weight of the machine, being labor-saving, being time-saving and high working efficiency, good separation effect of the grain and straw and low manufacturing cost for farmers in rice-growing regions. A cam is arranged on a shaft of a threshing roller of the thrasher. The thrasher drives the rotation of the threshing roller by a power machine and leads the rotation of the cam and a grain sieve is vibrated correspondingly, a bearing is downwardly pressed by the rotation of the cam and a transmission arm is driven by a bearing. A connecting bar is downwardly pressed by the transmission arm and the grain sieve is downwardly pressed by the connecting bar. Spring is drawn out by the grain sieve and the grain sieve is vibrated. The bearing is not pressed by the rotation of the cam, and the transmission arm is not pressed by the bearing, the connecting bar is not pressed by the transmission arm and the grain sieve is not pressed by the connecting bar, and the spring is backwardly retracted and meanwhile the grain sieve is vibrated. The grain and the straw are fallen and continuously bounced on the grain sieve by the up and down vibration of the grain sieve. The grain is downwardly fallen to a hopper and then to a grain collecting basket and the rice straw is shaken out from the front end of the grain sieve. The utility model has fast and good effect of separation of the grain and straw, high rate of the cleaned grain of a grain collecting basket, thus saving manpower for turning and sun-drying.

Description

The cam-type vibrating-screen thrasher

(1) technical field:

The utility model cam-type vibrating-screen thrasher relates to a kind of small-sized machine of the paddy of tempering.

(2) background technology:

The small-sized machine broken branch and leaf when threshing of paddy of tempering at present drops simultaneously in the paddy bucket, has beaten will spend behind the paddy and has much manually gone cleaning, teds surging paddy and also requires great effort time-consuming.The power threshing machine that begins on the market now to have some millet straws to separate is sold, but structure is complicated, and type is heavier, and the millet straw separating effect is undesirable, and cost is higher again, the difficult popularization in the rural area.

(3) utility model content:

The purpose of this utility model is that type is lighter for vast rice workspace peasant household provides a kind of structure simpler, and the millet straw separating effect is better, the minitype motivation threshing machine that cost is lower again.

Primary structure of the present utility model is: the thrashing roller axle is contained on the cross bar of frame both sides, on the axle of the roller left side, cam is installed, on the frame cross bar, transmission arm is installed, transmission arm one end is that bearing and cam are collided even, and the paddy sieve is being installed below the thrashing roller and on the afer bay, can be up and down before the paddy sieve, the paddy sieve is connected mutually with connecting rod one end, the connecting rod other end and transmission arm are movably connected, and spring one end links to each other with the paddy sieve, and the other end links to each other with frame, the thrashing roller belt pulley links to each other with the engine belt pulley, the engine belt pulley rotates and drives the thrashing roller belt pulley simultaneously, and thrashing roller rotates, and cam and then rotates, the and then vibration of paddy sieve, on the one hand, cam rotates and presses down bearing, and bearing drives transmission arm, transmission arm presses down connecting rod simultaneously, connecting rod presses down the paddy sieve, and the paddy sieve elongates spring, and the paddy sieve is vibrated; On the other hand, cam rotates not that last item holds, and bearing is not pressed transmission arm, and transmission arm is not pressed connecting rod, and connecting rod is not pressed the paddy sieve, and spring is just toward retraction, and the paddy sieve is vibrated equally.The period of the day from 11 p.m. to 1 a.m roller of thrashing is driven by belt pulley, very drives the vibration one on the other of paddy sieve again like a cork, and millet straw drops and ceaselessly bounces on the paddy sieve, and grain falls into funnel, falls into grain collecting basket again, and straw shakes out from paddy sieve front end.The utility model is simple in structure, more only 28 kilograms of types, and the millet straw good separating effect, cost is low again, and promotional value is arranged very much.

Fig. 2 is a cam-type vibrating-screen thrasher side structure schematic diagram.

Fig. 3 is a cam-type vibrating-screen thrasher cam gear structural representation.

Among the figure, 1, frame, 2, thrashing roller, 3, the roller belt pulley, 4, baffle plate, 5, cam, 6, transmission arm, 7, bearing, 8, connecting rod, 9, spring, 10, paddy sieve, 11, the iron net, 12, engine, 13, roller axle net, 14, funnel, 15, rain-proof shelter, 16, awning pole, 17, mop, 18, collection paddy frame.

(5) embodiment:

It is as follows to describe the utility model embodiment in detail referring now to accompanying

drawing

1,2,3.Threshing machine is made frame 1 with angle steel, and frame 1 shell is installed sheet metal baffle 4, the high 80cm of threshing machine, the wide 62cm in the left and right sides.An iron wire tortuous bow flute profile thrashing roller 2 is installed by central authorities at threshing machine, roller 2 diameter 24cm, and length is 60cm.The roller axle of thrashing roller 2 is contained on the frame 1 both sides cross bar, on the axle on thrashing roller 2 left sides, cam 5 is installed, transmission arm 6 is installed on frame 1 cross bar, transmission arm one end is equipped with bearing 7 and collides with cam 5, in that paddy sieve 10 is installed below the thrashing roller 2 and on the afer bay 1, iron net 11 is installed, iron screen distance 6mm in the middle of the paddy sieve 10, sieve left and right both sides in paddy and be with the high rubber sheet of 8cm, prevent that broken branch and leaf from falling into toward funnel 14.Connecting rod 8 one ends are connected mutually with paddy sieve 10, and the other end and transmission arm 6 are movably connected, and spring 9 one ends link to each other with paddy sieve 10, the other end links to each other with frame 1, and thrashing roller belt pulley 3 links to each other with engine belt pulley 12, and engine belt pulley 12 rotates and drives thrashing roller belt pulley 3 simultaneously, thrashing roller 2 rotates, cam 5 and then rotates, and cam 5 rotates and presses down bearing 7, and bearing 7 drives transmission arm 6, transmission arm 6 presses down connecting rod 8 simultaneously, connecting rod 8 presses down paddy sieve 10, and paddy sieve 10 elongates spring 9, and the paddy sieve is vibrated; Cam 5 rotates not that last item holds 7, and bearing 7 is not pressed transmission arm 6, and transmission arm 6 is not pressed connecting rod 8, and connecting rod 8 is not pressed paddy sieve 10, and spring 9 is toward retraction, and the paddy sieve is vibrated equally; The utility model utilizes threshing machine thrashing roller 2 to rotate, drive cam 5 and rotate, when making transmission arm 6, connecting rod 8, spring 9 when tight pine link to each other, the millet straw spring on paddy sieve 10 of dropping, grain whereabouts funnel 14 falls into grain collecting basket 18 again, straw shakes out from paddy sieve front end.Reached the purpose that millet straw separates effectively.On the axle of thrashing roller 2 both sides, roller axle net 13 is housed, straw twines and blocks the roller axle when preventing to thrash, metal wire rod is installed on the frame 1 at threshing machine top is done awning pole 16, at pole 16 awning 15 of setting up defences of putting on the shelf, rain-proof shelter 15 can be opened to receive and be applicable to farm work.Be provided with mop 17 in threshing machine frame 1 both sides, be convenient to move.Threshing machine drives with engine, and available 2.5 diesel engines or agricultural hand traction are moving, and the gasoline engine of also available 3.2 horsepowers drives.
