Abstract

The utility model belongs to a rice threshing machine. On the basis of an existing power paddy rice thresher, the utility model is added with a rice and straw separator and a rice conveyor belt, and a transmission system is correspondingly adjusted; thus, the thresher can automatically separate the rice and the straw, and can automatically load and unload the rice. The utility model has the advantage of time and labor saving.

Description

Rice thresher

The utility model belongs to a kind of rice threshing machinery.

The rice thresher that uses does not have grain-straw separating device and cereal conveyer belt at present, usually needs a people to drag for hair grass, pinch millet specially, wastes time and energy, and influences work efficiency.

The purpose of this utility model is to make a kind of new-type rice thresher, can realize automatically that basically millet straw separates, and the cereal dress cuts.

The purpose of this utility model is achieved in that this rice thresher mainly is made up of grain-containing barrel, grain-blocking cover, cylinder, engine and transmission system, cylinder is placed on the cruciform bracing of grain-containing barrel by drum shaft, the millet straw separator is housed respectively in the grain-containing barrel, the cereal conveyer belt, the millet straw separator is fixed in the top of grain-containing barrel with axle, and cereal used for conveyer belt axle is fixed in the middle part of grain-containing barrel; Its left side kind of drive is: engine drives drum shaft by driving-belt and rotates, and drum shaft drives the motion of cereal conveyer belt by driving-belt; The right side kind of drive is: the in-line gears on the drum shaft drive another gear, and the concentric sheath belt wheel on this gear drives the motion of millet straw separator by driving-belt.

The utility model has the advantages that: separate (1) automatically millet straw, and a hair grass is sent outside the standing grain bucket, and the paddy dustpan of packing into, very important person pinch paddy in bucket is not picked up grass, the saving labour.(2) simple in structure, cost is not high, sturdy and durable.(3) this machine can be adorned power, if the old-fashioned manpower threshing machine of also available manual operation only needs a workday just can reequip and finishes, uses, and is the same light with original rice thresher.

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:

Fig. 1 is a rice thresher left side transmission system schematic diagram;

Fig. 2 is a rice thresher right side transmission system schematic diagram;

Fig. 3 is a rice thresher millet straw cyclone separator arrangement schematic diagram.

As shown in Figure 1, 2, this rice thresher mainly is made up of grain-containing barrel 1, cylinder 2, grain-blocking cover 3, gasoline engine 11 and transmission system, cylinder is placed on the cruciform bracing 13 of grain-containing barrel by drum shaft 14, millet straw separator 16 is housed respectively in the grain-containing barrel 1, cereal conveyer belt 19, millet straw separator 16 usefulness axle 17 is fixed in the top of grain-containing barrel, and cereal conveyer belt 19 usefulness axle 18 is fixed in the middle part of grain-containing barrel; Millet straw separator 16 and cereal conveyer belt 19 all tilt to install, and be high slightly by gasoline engine 11 1 ends.During this machine work, the left side kind of drive is: gasoline engine 11 drives drum shaft 14 by belt 12 and cylinder 2 rotates, and drum shaft 14 drives cereal conveyer belt 19 by belt 15 and moves towards Way out; The right side kind of drive is: the in-line gears 21 on the drum shaft 14 drive another gear 22, and the concentric sheath belt wheel on this gear 22 drives 16 motions of millet straw separator by belt 23.

This millet straw separator 16 is for bamboo chip weaves a mat, and weaves into the endless belt of certain interval with bamboo chip 25 and ribbon 24, is convenient to grain and passes through.The below, left side of this grain-containing barrel 1 is provided with a breach 4, so that from then on the careless standing grain leaf of hair is exported.

During this machine work, the people stands on the pedal, holding paddy rice is placed on the platen, the cylinder 2 that the spike of rice contact is rotated, cereal and a small amount of standing grain leaf come off, and together fall on guarantor's grass separator 16 of left movement, and the standing grain leaf is exported by millet straw separator belt to breach 4, grain falls down to fall from the gap of millet straw separator and moves right on the cereal conveyer belt 19, is sent to the port of export and falls in the dustpan 5 of dress paddy.

This design also can apply on the manpower threshing machine, also can only establish the millet straw separator, does not establish the cereal conveyer belt, and running part adjusts accordingly.
