Description

Miniature electric paddy rice thresher

The utility model is that a kind of small-sized electric bow roller gear formula partly feeds paddy-eliminator.

Existing thresher kind is more; though large-scale paddy-eliminator function wherein is more complete; work efficiency is higher; but its structure all more complicated is huge, and manufacture difficulty is bigger, and cost is higher; also owing to generally will use three-phase alternating-current supply; and power consumption is more, thus be used for state farm or agriculture collective production unit more, and be not suitable for the current individuality production user in vast rural area.In recent years, some small-sized foot-operated Rice threshers having occurred, is 87216663 as number of patent application, 88212579,88218584 etc., though simpler and easy inexpensive, without power supply, can be used for the individual user of production in rural area, but owing to be used as power with manpower, brothers also use, disperse energy, labour intensity is bigger, and work efficiency is not high, generally per hour can only take off 100 kilograms of paddy, still can not be satisfactory.

The purpose of this utility model is to overcome the weak point of above-mentioned existing Rice thresher, and a kind of small-sized, simple and easy, inexpensive, electronic, efficient paddy-eliminator is provided, to satisfy the current individual user's of production in vast rural area urgent need.

The paddy-eliminator that the utility model provides, mainly by frame, threshing cylinder, connect a stream and send plate, transmission system and electromotor etc. partly to form.Rack section wherein mainly comprises left frame, left side frame, goes up crossbearer, and the frame connecting rod etc.; Threshing cylinder mainly comprises drum shaft, disk, reinforcing wheel, bow tooth plate and threshing bow tooth etc.; Connecing a stream send plate and fuselage backboard to make with same sheet metal bending; Transmission system mainly comprises big double grooved pulley, little double grooved pulley and V belt etc.; Also have the sheave centre-to-centre spacing that is fitted together with motor cabinet to adjust plate etc. in addition.

The utility model is compared with large-scale Rice thresher, owing to several major parts such as having saved separator, cleaning plant and conveying plant have only this most important work part of sheller unit, so structure is simplified greatly, cost reduces greatly, volume and weight is also corresponding to be reduced, and uses with maintenance very easy.Especially owing to adopted single-phase capacitance starter motor, power to have only 0.75 kilowatt, per hour energy charge has only 0.25 yuan, can utilize the general illumination power supply, is well suited for present rural power service situation.Sheller unit of the present utility model adopts roll form, but is not traditional enclosed cylinder, but surrounds a circular open type cylinder by the reinforcing wheel assembling of 10 wooden tooth plates and two cast iron disks and a steel, has both saved material, rotates light again.Simultaneously, the length of this cylinder is 1000 millimeters, has increased about one times than existing small-sized Rice thresher, if two people operate the computer simultaneously, can improve the work efficiency twice.Threshing bow tooth is also than the Gao Ermi of existing small-sized thresher, and adopts three helix arrangement modes, thereby the threshing better effects if, per hour can take off about 400 kilograms of paddy.When a lateral wearing of bow tooth is big, tooth plate can be unloaded tune and use opposite side, thereby prolong bow tooth service life.Transmission system of the present utility model, neither adopt the gear shift of large-scale Rice thresher, also do not adopt the sprocket wheel link chain mechanism of most foot-operated small-sized Rice threshers, but adopt the double grooved pulley V belt kind of drive, and adjustable center distance, thereby transmission of power steadily and skidding had not appearred in noiseless at work.In addition, this Rice thresher also has special-purpose flat faced pulley, when having had power-equipment such as small diesel engine as the user, can buy electromotor, unloads big grooved wheel and loads onto flat faced pulley and get final product work.

Product structure schematic diagram of the present utility model is seen accompanying drawing 1.Wherein 1 is the two sides frame, adopts casting, and processing capacity is few, good rigidly, and cost is low; 2 is last straight-bar machines frame, adopts angle steel, easily processing; 3 is the frame connecting rod, adopts the reinforcing bar manufacturing, has three, each one of front and back, bottom, one at middle part, back.

To go up straight-bar machines frame 2 with screw 5 and fixedly connected with machine frame at two sides 1 and be integral, three frame connecting rods 3 are connected left and right sides frame in aggregates again.The body rear board and the grain of rice receive stream and send the steel plate of same 0.8 millimeters thick of plate 4 usefulness to make, its upper edge is contained in the medial surface of straight-bar machines frame 2 angle steel with screw 6, its the right and left is along the back vertical rod of being close to left and right sides frame, constitute the fuselage backboard, be bent into ramped shaped to the front lower place under the cylinder again until the middle part and be used to receive the grain of rice and the stream taken off and send out, its lower edge wraparound is on the stand connecting rod 3 in front, bottom.The above-mentioned parts fuselage that forms a whole has enough rigidity, places steady jail, and the mounting or dismounting maintenance is very convenient.The core of this Rice thresher is a threshing cylinder, and threshing bow tooth 14 wherein adopts the strong high-quality steel wire of 5 millimeters rigidity of diameter to curve V-type, and 60 millimeters of height amount to 165, adopt three helix modes to arrange, and are installed on 10 bow tooth plates 13.Bow tooth plate 13 adopts the hard wood manufacturing, is easy to processing, and is with low cost.10 bow tooth plates surround a cylindrical shape, 300 millimeters of diameters, and 1000 millimeters of length, two ends are contained on two cast iron disks 8 and can reverse end for end and use, and the centre has a steel to reinforce wheel 15, is used for strengthening the cylinder rigidity.Disk 8 is contained in the two ends of drum shaft 7, tightens fixing with back of the body cap 9.Above-mentioned parts are formed a threshing cylinder assembly.Respectively there is a bearing assembly at the middle part of machine frame at two sides 1, and 10 is bearing block, and 11 is bearing cap, and 12 is bearing, and cylinder shaft 7 just is contained on these two bearings.This shaft extension goes out an end of frame and adorns a bigger double flute pulley concial disk 16.Its bottom adorns one 0.75 kilowatt single-phase motor 20, adorns a less double flute pulley concial disk 18 on the motor shaft.17 is two V belts.21 is motor cabinet, is contained on the stand connecting rod 3 in front of bottom.22 is motor lift adjustment plate, is used for adjusting the centre-to-centre spacing of two two-groove belt pulleys, makes the elasticity of V belt suitable.If without motor as power, and use small diesel engine, can unload the big grooved wheel 16 on the drum shaft 7, change flat faced pulley, as usual work.19 is the protective cover of transmission system, with sheet metal or galvanized iron sheet manufacturing.The appearance and size of this Rice thresher is 1100 * 650 * 700 millimeters, and gross weight is a 105 kg, threshing cylinder tangential velocity 11 meter per seconds, take off rice efficient 350-400 kilogram/hour, clean rate 98%, percentage of damage 0%, total loss rate 0.5%.
