Abstract
The utility model relates to a chain driven pedal thresher, which a pedal (1), a machine frame (2) which is integrally connected with a charging basket (8). The utility model is characterized in that the chain driven pedal thresher also comprises a secondary transmission speed increasing mechanism composed of a connecting rod (3), a chain wheel (4), a chain (5), a flywheel (6) and a roller assembly (7). The utility model has the advantages of duration of machine parts, stable operation, flexible rotation, labor saving, low noise, light weight, good threshing effect, etc., and can solve the problems of big noise, high labor intensity, fussy disassembly and assembly, unfavorable transportation to farmlands of the existing gear type transmission pedal thresher.
Description
A kind of chain transmission type is ridden thresher, belongs to the agricultural machinery of rice threshing.
Existing rice threshing thresher generally adopts gear type secondary drive mechanism.There is following shortcoming in this foot-operated thresher: live load is heavy, and labour intensity is big, and work efficiency is low, the about 100kg of single per hour threshing, and movable part is easy to wear, and noise is big, and the relatively poor peasant of muscle power uses comparatively difficulty.
The purpose of this utility model is to avoid weak point of the prior art and provides a kind of parts durable, and interchangeability is good and repair is simple and easy, rotates flexibly, and running is stable, noiselessness, and friction is little, and live load is light, and the labour-saving chain transmission type is ridden thresher.
The utility model is achieved in that the general purpose accessories such as sprocket wheel, chain, flywheel of the homemade load bicycle of utilization constitute secondary transmission speedup system.Connecting rod moves and connects with sprocket wheel, pedal hinge.Flywheel tightens up with an end of roller assembly gyroaxis and connects.Sprocket wheel (one links to each other with charging basket) on frame does not come off when flywheel makes cylinder work to ensure that chain drives by centralized positioning axle and location-plate (not shown) location and the specific geometric position of flywheel maintenance.In addition, the eccentric interface of connecting rod and sprocket wheel is determined.The fulcrum of pedal on frame keeps one to determine distance to the tie point with connecting rod, and the length of pedal is also determined.When operating personnel when pedal is up and down reciprocatingly stepped on, connecting rod drives sprocket rotation, drives the rotation of flywheel speedup by chain, makes roller assembly work.
With the foot-operated thresher ratio of existing gear driven type, the foot-operated thresher that the utility model provides is simple in structure, same working method shows that the threshing effect is good, single per hour threshing 150～200kg, and body weight is light, the about 30kg of gross weight, convenient disassembly, the body that has assembled do not need to carry any instrument, only draw off chain with a small wooden in several seconds, roller separation is taken off, and one or two relatively poor peasant of muscle power just can move thresher to paddy field.Very suitable mountain area and rice field disperse peasant household's effect in area.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a kind of structural representation of the foot-operated thresher of a kind of chain transmission type of the present utility model.
In Fig. 1: (1) pedal, (2) frame, (3) connecting rod, (4) sprocket wheel, (5) chain, (6) flywheel, (7) roller assembly, (8) charging basket, (9) shelves cover.
As shown in Figure 1: roller assembly (7) is made of cylinder and rotary middle spindle; Charging basket (8) links to each other with frame (2) and constitutes an integral body; The center of rotation pedestal of roller assembly (7) is on frame (2), the one end tightens up the location with flywheel (6) and connects, the other end tightens up by handle screw (not shown) and frame (2) and joins, and sprocket wheel (4) is linked to each other by chain (5) with flywheel (6); Sprocket wheel (4) and the specific centre-to-centre spacing of flywheel (6) are more than or equal to 193mm, and two central horizontal distance is 155mm; Connecting rod (3) and moving connection of the eccentric hinge of sprocket wheel (4), its eccentric throw is 60mm; Connecting rod (3) and pedal (1) tie point are 210mm to the air line distance of the eccentric tie point of sprocket wheel (4); Pedal (1) is 135mm at the fulcrum of frame (2) to the distance of the tie point of connecting rod (3); The length of pedal (1) is 335mm; The direct frame of shelves covers (9) is in the top of an end and the roller assembly (7) of charging basket (8).Whole system has constituted the foot-operated thresher of chain transmission type of secondary speedup.
During operation, the location-plate (not shown) of sprocket wheel (4) on frame (2), can regulate the degree of tightness of chain (5), roller assembly (7) can be adjusted front and back in frame (2), make flywheel (6) and sprocket wheel (4) keep a straight line to be as the criterion, it is little to reach amplitude of fluctuation, and stable drive is avoided chain releasing.As the foot-operated thresher operation of existing gear type transmission, as long as pedal up and down reciprocatingly, cereal such as spike of rice are leaned against the cylinder top just can roll and take off totally.
Claims (3)
1, a kind of foot-operated thresher, constitute by pedal, connecting rod, sprocket wheel, chain, flywheel, frame, charging basket, roller assembly, shelves cover etc., it is characterized in that: connecting rod and sprocket wheel off-centre are hinged, sprocket wheel is connected with flywheel by chain, has constituted the transmission speedup system of the foot-operated thresher of a whole set of chain transmission type.
2, foot-operated thresher according to claim 1 is characterized in that: sprocket wheel is positioned a side of frame by centralized positioning axle and location-plate, and adjusts its position before and after can making sprocket wheel.
3, foot-operated thresher according to claim 1 is characterized in that: flywheel tightens up axle center one end that is positioned roller assembly, and is connected with sprocket wheel by chain.
