Abstract

The utility model relates to a hulling machine for wheat with double screw rods, mainly composed of a casing body, a charging hopper, a screw rod and a pressure adjusting gate. A left screw rod and a right screw rod which are of opposite rotating directions and opposite turning directions are positioned in the casing body in parallel; the wet wheat which falls into the casing body from the charging hopper is ensured to be peeled under the press and the push of the rotating left screw rod, the right screw rod and the inner wall of the casing body and the friction among the wheat by the regulation of the pressure adjusting gate which is arranged on the rear end of the casing body. The utility model has the advantages of good peeling effect, high productive efficiency and low energy consumption.

Description

Double-screw arbor hulling machine for wheat

A kind of twin-screw wheat thresher of the utility model relates to the processing of giving of grain milling, and specifically a kind of wheat debranner machinery mainly is made up of housing, hopper, screw rod and pressure regulation door.

Employed wheat thresher in the existing wheat debranner flouring technology, be divided into dry method (wheat does not add water infiltration) and two kinds of technologies of wet method (wheat adds water infiltration), all be use vertical abrasive type rice whitening machine or horizontal iron, the sand double roll rice polisher is finished wheat debranner processing.The major defect of these two kinds of equipment is that low, the supporting power of efficient is big, consumed power is more, directly influences the popularization of wheat debranner flouring technology.

The purpose of this utility model is to overcome the deficiencies in the prior art, discloses a kind of mechanical structures that is exclusively used in wheat debranner technology, has the characteristics of the high and low energy consumption of production efficiency, provides a kind of suitable machinery for promoting the wheat debranner flouring technology.

A kind of twin-screw wheat thresher of the utility model, mainly form by housing, hopper, screw rod and pressure regulation door, the technical scheme that realizes the utility model purpose is: rotation direction is opposite, turn to that also opposite left-handed screw and right handed screw are parallel to be placed in the housing and by the engaging tooth train transmission between fore bearing support and rear bearing rack, the lower end outlet that is fixedly mounted on the hopper on the housing is communicated with the housing inner chamber, the housing rear end is provided with pressure regulation door, and the housing front end is fixedlyed connected with rear bearing rack and sealed by rear bearing rack.

When using a kind of twin-screw wheat thresher of the utility model to carry out the wheat debranner operation, engine rotates from right handed screw front-end driven (for example utilizing belt pulley) right handed screw, the right screw rod that rotates drives left-handed screw by the engaging tooth train and rotates with counterturn, the wheat that process adds behind the water infiltration is fallen in the housing by hopper, the left-handed screw that wheat is rotated in housing, the mechanical presses of right handed screw and inner walls, stronger interior friction between friction and wheat, make wheat epidermal area and endocarp pull-up from, realize wheat debranner, simultaneously, wheat moves to the housing rear end under the promotion of left-handed screw that rotates and right handed screw, giving when putting pressure of the pressure regulation door that movement pressure is provided with greater than the housing rear end, promptly push pressure regulation door open, the wheat of having peeled flows out from pressure regulation door, finishes wheat debranner technology.Suitably regulate giving of pressure regulation door and put pressure, can regulate the wheat required frictional force of in housing, peel, guarantee to be the wheat of having peeled from the pressure regulation door outflow.In sum, a kind of twin-screw wheat thresher of the utility model structure is simpler, and cost is lower, guarantee the wheat debranner processing quality by regulating pressure regulation door pressure, it is effective to peel, the production efficiency height, energy consumption is low, has realized the purpose of this utility model preferably.

Below in conjunction with accompanying drawing a kind of twin-screw wheat thresher of the utility model and embodiment are described in further detail.

Fig. 1 is an example structure schematic diagram of a kind of twin-screw wheat thresher of the utility model;

Fig. 2 is the plan structure schematic diagram of Fig. 1.

An embodiment as a kind of twin-screw wheat thresher of the utility model, as shown in Figure 1, 2, mainly form by housing, hopper, screw rod and pressure regulation door, rotation direction is opposite, turn to that also opposite left-handed screw 7 and right handed screw 8 are parallel to be placed in the housings 5 and by engaging tooth train 3 transmissions between fore bearing support 2 and rear bearing rack 4, the lower end outlet that is fixedly mounted on the hopper 6 on the housing 5 is communicated with housing 5 inner chambers, housing 5 rear ends are provided with pressure regulation door 10, and housing 5 front ends are fixedlyed connected with rear bearing rack 4 and sealed by rear bearing rack 4.As illustrated in fig. 1 and 2, the driving of a kind of twin-screw wheat thresher of the utility model for example can be that engine is realized by the belt pulley 1 that is installed on right handed screw 8 front ends.

For guarantee that wheat is not excessively damaged in the decortication operation, reduce the loss in the decortication operation as far as possible, as preferred embodiment, as depicted in figs. 1 and 2, spiral 9 on left-handed screw 7 and the right handed screw 8 preferably all is to be curled up by round steel (for example using the round steel of φ 10) to form, be fixedly welded on left-handed screw 7 and the right handed screw 8, and manufacturing process is simple, because spiral 9 surfaces are circular arcs, so in extruding, when promoting wheat mainly is to utilize friction effect to finish wheat debranner, and does not cause the wheat breakage to cause damage.

According to the wheat physical dimension rule that China produces wheat, as the good example of preferable reality of a kind of twin-screw wheat thresher of the utility model, preferably: the distance between left-handed screw 7 and the right handed screw 8 is 2 millimeters; Left-handed screw 7, right handed screw 8 are the 8-10 millimeter with the gap of housing 5 inwalls; Housing 5 inwalls are Alveolus type (available wear resistant cast iron is cast), can better satisfy the requirement of wet method wheat debranner technology like this.
