Abstract

The utility model relates to an agricultural threshing machine, in particular to a practical thresher for crops such as rice, cockle, rapeseed, etc. On the basis of ship-like thresher, the utility model installs an arch protection cover on the upper front part of threshing cylinder of hopper. A transmission mechanism of pedal lever eccentric wheel is installed at the left end of the rotary shaft of threshing cylinder, and a triangle belt transmission wheel is installed at the right end. With simple structure and reasonable design, the utility model can be used in paddy farmlands and fields and driven by a variety of powers. In addition, the installation is simple, and use safely.

Description

Follow-on ship shape rice-wheat thresher

Technical field

The utility model relates to a kind of agricultural thresher machine, the practical thresher of crops such as particularly a kind of rice wheat, buckwheat, rape.

Background technology

Traditional threshing machine is mainly used in the operation of thrashing on the threshing ground; incompatibility is carried out operation between the paddy field; and many peasants that are located in remote mountain area will transport to paddy and wheat that the threshing ground goes is very inconvenient; therefore need a kind of a tractor serves several purposes, can utilize various energy resources, adapt to various power and can operation on paddy field, field, the rice-wheat thresher of the threshing multiple kinds of crops that suits.

Chinese patent literature 96242357.2 has proposed to adapt to the operation nearby in the paddy field, and can utilize the ship shape threshing machine of various energy resources.This technical scheme has solved the demand in the paddy field threshing preferably, and some need further improve part in addition but its design is gone up.For example original hopper top was opened wide, the spatter loss when preventing threshing cereal, and the mode that the peasant gets only the paulin strut temporarily solves, but still loses morely in the paddy field, and open design is to the dangerous hidden danger of child in addition; And for example there is customization the installation site of the transmission mechanism at threshing cylinder rotating shaft two ends, and for the user who is unfamiliar with machinery, the mistake of installation is easy to damage machine.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of follow-on ship shape rice-wheat thresher, and it is reasonable in design, can the field, paddy field and on threshing, and can use multiple power, spatter loss is few during work, fitting operation is easy, and is safe in utilization.

Solving the scheme that technical problem of the present utility model adopts is: adorn a ship type tray in the bottom of existing hopper, threshing cylinder rotating shaft two ends are equipped with respectively on the ship shape threshing machine basis of two cover transmission devices, the protective cover of arc is installed at the threshing cylinder front upper part of hopper, pedal lever eccentric wheel transmission mechanism is loaded on the threshing cylinder rotating shaft left end of operation position, and right-hand member is then installed the V belt drive.

These the beneficial effects of the utility model are: the ship type tray of hopper bottom has increased the area of bottom, can use in the paddy field and sagging, can make things convenient for the peasant with regard near operation, raises the efficiency; In the threshing cylinder rotating shaft two cover transmission device makes this thresher both can artificial threshing when condition is relatively poor, again can be when conditions permit working power machinery, reduce labor intensity.

Description of drawings

Fig. 1 is a side structure schematic diagram of the present utility model, and promptly foot-operated eccentric gear auxiliary driving realizes the hand threshed schematic diagram;

Fig. 2 is an opposite side structural representation of the present utility model, and promptly the V belt transmission mechanism is realized motor-driven threshing schematic diagram.

Each label is represented successively among the figure: pedal lever eccentric wheel transmission mechanism 1, external gear transmission 2, threshing cylinder 3, hopper 4, ship shape tray 5, pulley concial disk 6, arc protective cover 7, dynamic power machine mount pad 8.

Embodiment

Referring to Fig. 1; hopper 4 left sides in the operation position; be connected with external gear transmission 2 by pedal lever eccentric wheel transmission mechanism 1; the pinion of external gear transmission 2 again with threshing cylinder 3 coaxial rotation; the operator steps on pedal up and down, and threshing cylinder 3 is rotated, and the multiple sets of teeth pawl of installing on the threshing cylinder 3 is finished threshing work; the grain of taking off falls into the hopper 4 of cylinder below, realizes artificial foot pedal threshing machine.Can not be at traditional threshing machine in the deficiency of very soft paddy field operation; the custom-designed ship shape tray 5 of the utility model is installed in the bottom of hopper 4; ship shape tray 5 should adopt wood materials; increased contact area and the buoyancy of thresher in the field, paddy field; make thresher can depression in the paddy field, more adapt to the operation nearby in paddy field.

For power or other power resources that make full use of small hand tractor alleviate the heavy manual labor of peasant, the utility model as shown in Figure 2, adorned a cover pulley concial disk 6 at the rotating shaft right-hand member of threshing cylinder 3, motor or hand drawing force source (as diesel engine) are contained on the dynamic power machine mount pad 8 on hopper 4 right sides, be connected to pulley concial disk 6, during use, again pedal lever eccentric wheel transmission mechanism 1 and external tooth wheel set 2 are thrown off, just can realize the motor-driven threshing of this machine, and install very simply, wrong phenomenon can not occur adorning.

The spatter loss of cereal during at threshing (especially Tanaka) will be adorned iron sheet system arc protective cover 7 at the front upper part of hopper 4, the spatter loss during with minimizing threshing cereal, and eliminated the dangerous hidden danger that one side child is existed.

Claims

1, a kind of follow-on ship shape rice-wheat thresher; a ship type tray is adorned in the bottom of hopper; two cover transmission devices are housed respectively at threshing cylinder rotating shaft two ends; it is characterized in that: the protective cover that arc is housed at the threshing cylinder front upper part of hopper; pedal lever eccentric wheel transmission mechanism is loaded on the threshing cylinder rotating shaft left end of operation position, and right-hand member is installed the V belt drive.

2, by the described follow-on ship shape rice-wheat thresher of claim 1, it is characterized in that: the hopper right side in the operation position is connected with the dynamic power machine mount pad.
