Description

The portable type rice harvester

The utility model belongs to the agricultural machinery class, particularly a kind of rice harvester.

Be subjected to the restriction of paddy growth characteristic, it is easy to implement like that the mechanized harvest of paddy rice can not show a candle to the mechanized harvests of dry crops such as wheat.Large-scale combine is multiple functional, dependable performance, effect height, but too heavy, when paddy-field-working, can't advance at all, and more or not its ample scope for abilities to the fritter rice field that disperses.In recent years some small-sized rices harvesting shelling facility that occur to a certain extent can operation in the fritter rice field, its function singleness, and only cutting of having do not taken off, and only taking off of having do not cut, though can the instead of part hand labour, that its effect improves is little.

The purpose of this utility model is that the rice harvester that cuts one is taken off in a kind of light practicality of development.

The purpose of this utility model realizes by following technical proposals: adopt the conveyor screw rotation to carry out threshing-before-cutting in one, make grain header miniaturization lighting.The utility model is made up of frame, shelling system, diced system and transmission system.The shelling system is a rack-mounted conveyor screw, and its front portion is an ear collection device, and the rear portion is a threshing device, and rotating shaft tightens intrinsic large umbrella gear.Sea whelk on the threshing device and periphery form the shelling groove, and the shelling tooth is arranged in the groove.Belt pulley, driving gear and the same rotating shaft of I small umbrella gear, belt pulley is connected with powered pulley on the engine by belt, large umbrella gear engagement in I small umbrella gear and the conveyor screw rotating shaft, driving gear and driven wheel engagement, the connecting rod that is enclosed within on the driven wheel end face edge eccentric shaft is connected with motion.Diced system is a disc-shaped cutting tool, and its rotating shaft is fixed on the frame by bearing sleeve, the II small umbrella gear on rotating shaft top and large umbrella gear engagement.Operation principle of the present utility model is such: the power that is provided by engine drives connecting rod on conveyor screw, cutter and the driven wheel by transmission system, and connecting rod actuation movement mechanism pushes ahead complete machine.Meanwhile, along with spirochetal rotation, the paddy rice grain ear is drawn and is admitted in the shelling groove on the threshing device by ear collection device, and the comb of shelling tooth gets rid of under the effect of tempering grain and laid by comb in groove, drops on following connecing and contains in the container.The rice bar is after leaving conveyor screw, and the disc-shaped cutting tool that is being rotated cuts off from root, draws in and be unlikely to for the ease of spike of rice to shift to an earlier date shelling, and the ear collection device of conveyor screw front portion is made turriform.Motion can be two spiral propellers, by being installed in the below on frame both sides movingly respectively.On the axle of spiral propeller rear end oriental toothed gear is housed, is connected with connecting rod on the driven wheel eccentric shaft by lever, the reset tension spring that can regulate the chain pull power is housed on the other end around thereon chain one end.When driven wheel was driven by driving gear, the connecting rod on it was done motion up and down.Upwards spur chain by lever when connecting rod moves upward, oriental toothed gear rotates and drives spiral propeller, and grain header is pushed ahead; Extension spring resetted chain but oriental toothed gear does not change when connecting rod moved downward.Grain header is periodically intermittently pushed forward like this.But because connecting rod short frequency height of the period of motion up and down, intermittency is also not obvious.In order to make the harvesting function keep straight ahead, left and right sides spiral propeller is reverse thread each other, and corresponding two oriental toothed gears are also oppositely installed thereupon each other.Simultaneously, two extension springs are adjustable to the pulling force power of chain, with the pace of control grain header and about turn.When regulating extension spring to chain pull strong and weak, be exactly to change the reset size of angle of oriental toothed gear in fact, just change the each intermittently size of rotational angle of spiral propeller, thereby reach the purpose of control grain header pace speed.Equally, about making by adjusting two extension springs to the pulling force of its chain when uneven, about two each angles of intermittently rotating of spiral propeller just occur unevenly, make the pace inequality on frame both sides, thus realize grain header about turn.Motion also can adopt 1 or 2 anti-pulley, is installed in the frame back, in its rotating shaft (when adopting two anti-pulleys is common shaft) oriental toothed gear is housed.One end of driving rod is fixed on the oriental toothed gear cylindrical (can positive and negative rotating part), and the other end is lived with the connecting rod on driving halogen wheel eccentric shaft and is connected.When connecting rod moved up and down, anti-pulley is also directed intermittently to rotate, and promotes grain header and advances.Disc-shaped cutting tool can be worn into sawtooth or blade, and the length of its rotating shaft is made extension type to regulate the lifting of cutter, promptly regulates the height of toothing.Cutter also can adopt two, and parallel installation relatively rotates, and cuts off rate with raising.The frame height is also made adjustable, to adapt to the needs of different cultivars paddy rice rice bar height.Both sides also are equipped with the ship shape skid plate below the frame, to increase its buoyancy.Half loudspeaker tubular shelves paddy plate is installed above the threshing device, pre-large post-small, with the paddy guiding container of taking off.On the frame of the ear collection device left side wedge shape demarcation strip is installed also, the paddy rice of operation row is separated.Also the exhaust of engine can be guided to by the ear collection device, be utilized wind-force to strengthen the spike of rice collection and hold together effect as need to advance fringe from the right side to gather in, conveyor screw need only be made the left-hand thread conveyor screw, transmission system gets final product from left side driven in rotation.Also must on the frame below the threshing device, place grain before the use and connect the Sheng container.

The utility model portable type rice harvester is practical, and is simple in structure, rationally distributed, maneuverability, dependable performance, easy to manufacture, cheap, in light weight, volume is little, and operation easily, the efficient height, be the hand harvest 4-10 doubly, the operation width is the capable paddy rice of 1-2, is particularly suitable for the harvesting of peasant household paddy rice on the fritter rice field that disperses.Also can use as threshing machine separately in case of necessity.

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