Abstract
The utility model belongs to a threshing machine in a rice and wheat harvesting machine, which comprises a machine frame, an upper cover, a feed hopper, a material protecting board, a back guide board, a front guide board, etc. The utility model is mainly characterized in that the utility model is provided with a movable tooth type rolling cylinder, both ends of a main shaft of the movable tooth type rolling cylinder are provided with bearing seats which are connected with the machine frame, and a concave board and a straw sliding board are arranged under the movable tooth type rolling cylinder. A funnel is connected to the lower part of the movable tooth type rolling cylinder, a vent sleeve is arranged under the funnel, and a fan is arranged at the front end of the funnel. A shutter type inclined guide board is arranged in the funnel, and an impurity division board is arranged at the tail end of the vent sleeve. The utility model collects the advantages of a rasp bar and a spiked thresher into one body, and the combination work of threshing and winnowing is realized.
Description
The utility model belongs to the thresher machine in the rice wheat harvester tool.
The facility that are used for paddy rice or wheat threshing at present mainly divide full feeding type and half feeding type.Because full feeding type is applicable to wheat, paddy rice and soybean, corn, jowar etc., for this reason, relatively is applicable to the north.Full feeding type thresher mainly is divided into the drum with rasp bars formula, nail tooth drum formula, double drum type, axial flow cylinder-type and vane type.Because back three kinds of types are big, structure is comparatively complicated; and because the variation of China's rural economy situation in recent years; the large and medium-sized thresher scope of application is very limited; trend towards developing small-sized thresher; some R﹠D institution and factory have done a lot of work to small-sized thresher, but all do not walk out rasp bar and spiketooth type threshing with regard to the threshing mode.Drum with rasp bars formula thresher, operation quality is good, but because the restriction of structure, feed quantity is big slightly, and stuck phenomenon is serious, inefficiency.Be mainly used in and take off wheat.Nail tooth drum formula thresher, better to inhomogeneous feeding adaptability, but the straw grass is disconnected broken more, and power consumption is big, is used to the rice that dewaters.The common drawback of these two kinds of types is that threshing efficiency is low; power consumption is big; the complete machine heaviness, for solving the problem that above-mentioned two kinds of types exist, the patent No. is 93243420; name is called the patent of " multifunction micro thresher "; hammer leaf in the beater disintegrating machine is introduced thresher, strengthened the ability of rubbing, improve threshing efficiency; reduce power consumption, but also brought the high problem of percentage of damage.
The purpose of this utility model will provide a kind of many usefulness, energy-conservation, simple in structure, easy to operate, applied widely exactly, and percentage of damage meets the oscillating tooth grain separator of industry related standards.
For realizing the purpose of this utility model, mainly adopted:
1. the hammer slice type threshing cylinder is changed into oscillating tooth formula threshing cylinder.
2. change the oscillating tooth shape, make it to help rubbing.
3. at the two ends of cylinder, two end plates are housed,, keep speed stability to increase the rotary inertia of cylinder.
4. with the arrangement of movable tooth, be the boundary with the center, form bifilar helix, during work, crops are concentrated to the centre, to increase the effect of rubbing between the crop.

The utility model (Fig. 1, total weight Fig. 2) is born by frame (3), cover (15) is equipped with in frame (3) upper end, last cover (15) one termination feeding hoppers (10), protect flitch (11), back guide (12), the other end connects jaw (18), front guide (16), the lower-left end of frame (3) is equipped with monophase machine (4), land wheel (1) is equipped with in the bottom, its main feature is in the below of last cover (15) oscillating tooth formula cylinder (13) to be arranged, the two ends of its central shaft have bearing block and frame (3) to be connected, the below of oscillating tooth cylinder (13) is provided with notch board (9), slip careless plate (17), connect funnel (8) under it, there is air duct (7) below of funnel (8), the bottom is put out cereal mouthful (2), the front end of air duct (7) is equipped with fan (5), is the slope guide plate (6) of louvre type structure in it, at the end of air duct (7) impurity separating plate (19) is housed.
Oscillating tooth threshing cylinder of the present utility model (Fig. 3), be at the two ends of main shaft (24) end plate (20) to be housed, there is a dish (23) centre, is evenly distributed with bearing pin (22) on the circumference of end plate (20), each bearing pin (22) is distributed with oscillating tooth (26), has spacer (21) to separate between the oscillating tooth.
The arrangement (Fig. 4) of oscillating tooth of the present utility model on bearing pin (22) is the boundary with the center, and it is 0.5～2mm that the formation bifilar helix makes the distance of the movable tooth on adjacent two bearing pins (22).
The utility model oscillating tooth (Fig. 5) structure is 8 font structures.
The utility model collection rasp bar, spike-tooth thresher advantage be in one, the tooth-like threshing cylinder of employing activity; compare with the spike-tooth threshing cylinder with rasp bar; save power 16～30%, realized the threshing and cleaning integration of operation, wheat, paddy rice, legume crop are all had the good working quality.In the course of the work, when feeding is inhomogeneous, under the spiral operation of movable tooth, control evenly: when feed quantity is excessive, movable teeth directional post deflection is regulated the gap automatically, is taken off crop to dish out continuously, removed stuck phenomenon, power consumption is less, and production efficiency improves greatly.Every performance indications have met or exceeded national standard, become grain threshing operation one much progress.
