Abstract

The utility model relates to a fitting part of agricultural machinery, in particular to a combine rethreasher shell. The shell comprises a cylindrical rethreashing cavity; one side plane of the rethreashing is provided with a shaft hole and the other side is provided with an end cover; the curved surface of the rethreashing cavity is provided with a throwing barrel connector. The utility model is characterized in that the throwing barrel connector is a fork horn and the opening at the connection part with the rethreashing cavity is larger than the opening at the bottom and at the connection part with the throwing barrel. With the rethreasher shell, the corn seeds are not blocked and the throwing barrel matched with the shell has small size.

Description

Combine rethresher shell

Technical field

The utility model relates to a kind of accessory of agricultural machinery, is a kind of combine rethresher shell specifically.

Background technology

Self-propelled combine all is to utilize rethresher that cereal kernel is broken away from usually, the shell of rethresher is a cylindrical spiral case, be connected with the tube of tossing on the spiral case, be provided with an impeller and washboard in the spiral case, impeller is fixedly mounted on the tailing auger shaft and by the tailing auger shaft driven rotary, drive cereal produces rubbing on washboard action in the time of the impeller rotation, then cereal kernel is dished out from the tube of tossing together with the shell of taking off.Because spiral case is connected for logical tube with the tube of tossing, the cereal kernel flow is easy to generate obstruction in the time of big, can solve blocking problem though strengthen the diameter of the tube of tossing, and also brings volume to increase simultaneously, the installation difficulty, waste of raw materials, the problems such as an availability is low of tossing.

Summary of the invention

The purpose of this utility model provides the long-pending little combine rethresher shell of a kind of cylindrical shell that do not stop up, tosses.

For achieving the above object, the utility model is by the following technical solutions:

Combine rethresher shell described in the utility model, comprise the columned chamber of taking off again, take off again on the side plane in chamber and have axis hole, opposite side has end cap, on the curved surface that takes off the chamber again, have the socket joint mouth of tossing, it is characterized in that: the socket joint mouth of tossing is a horn mouth, with the opening of the opening that takes off the chamber connecting portion again greater than its end and a connecting portion of tossing.

Have service hatch on the curved surface that takes off the chamber again, the loose-leaf lid is installed on the service hatch, the loose-leaf lid has the curvature identical with the curved surface that takes off the chamber again, and a side of loose-leaf lid is connected by hinge takes off on the chamber again, and opposite side is connected again by buckle and takes off on the chamber.

The toss cross section of socket joint mouth is a rectangle, its axis and the axis normal of taking off the chamber again, and by taking off the center of circle, chamber again; The socket joint mouth of tossing is positioned at the sidewall of axis hole one side and takes off the parallel sidewalls that the chamber has axis hole again, and is connected in one with it; The sidewall that the socket joint mouth of tossing is positioned at end cap becomes 30-60 degree angle with end cap.

The obstruction of combine rethresher mainly is to stop up easily with the exit of a connecting portion of tossing taking off the chamber again.After adopting technique scheme, take off the chamber again and effectively alleviated blocking up of cereal kernel with the horn mouth of the socket joint oral area position of tossing, angled side walls also has the effect of dredging to cereal kernel simultaneously, and the guiding cereal kernel enters the tube of tossing by outlet as early as possible.Loose-leaf lid on the service hatch can be opened easily, is convenient to take off again the installation and the maintenance of chamber inner body.

Fig. 1 is the structural representation of this practical a kind of embodiment;

Fig. 2 is to use the assembling schematic diagram of the rethresher of this shell;

Fig. 3 is the cutaway view of this practical a kind of embodiment.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Combine rethresher shell shown in Fig. 1,3, comprise the columned chamber 1 of taking off again that surrounds with iron sheet, take off again on the side plane in chamber 1 and have axis hole, be used for installing screw conveyor shaft 5, have end cap 2 on the opposite side plane, end cap 2 usefulness bolts are connected on the shell curved surface that takes off chamber 1 again.On the curved surface that takes off chamber 1 again, have the socket joint mouth 3 of tossing, be used for connecting the tube of tossing.The socket joint mouth 3 of tossing is horn mouth, its opening terminal greater than it with the opening that takes off chamber 1 connecting portion again and a connecting portion of tossing.That is to say bell-mouthed big mouth towards taking off chamber 1 again, osculum is towards the tube of tossing, and the opening of osculum is identical with the cross section opening of the tube of tossing.On the curved surface that takes off chamber 1 again, also have service hatch, loose-leaf lid 4 is installed on the service hatch, loose-leaf lid 4 has the curvature identical with the curved surface that takes off chamber 1 again, and a side of loose-leaf lid 4 is connected by hinge 41 takes off on the chamber 1 again, and opposite side is connected by buckle 42 and takes off again on the chamber 1.

The toss cross section of socket joint mouth 3 can be that rectangle also can be circular, but considers preferred rectangle from the production technology angle.Its axis and the axis normal of taking off chamber 1 again, and by taking off the center of circle in chamber 1 again; The socket joint mouth 3 of tossing is positioned at the sidewall of axis hole one side and takes off the parallel sidewalls that chamber 1 has axis hole again, and is connected in one with it; The socket joint mouth 3 of tossing is positioned at 2 one-tenth 30-60 degree of a sidewall and end cap angle of end cap 2.

As shown in Figure 2, this rethresher shell in use, be installed in the end of screw conveyor shaft 5 by the axis hole of one side, fixedly connectedly on the axis hole madial wall decide scratching plate 6, decide the end of the screw conveyor shaft 5 in scratching plate 6 outsides and moving scratching plate 7 is installed by feather key, decide to have tongue and groove on the relative face of scratching plate 6 and moving scratching plate 7, the arranged outside of moving scratching plate 7 has the flabellum vertical with card 8, is provided with stage clip 9 between moving scratching plate 7 and end cap 2.

During work, screw conveyor shaft 5 drives moving scratching plate 7 rotations, makes to decide scratching plate 6 and the 7 generation relative motions of moving scratching plate.Simultaneously, screw conveyor shaft 5 is transported to cereal kernel in the space of deciding between scratching plate 6 and the moving scratching plate 7, and after through rubbing action threshing, cereal kernel is transported to the another side of moving scratching plate 7, is stirred by flabellum 8, and socket joint mouth 3 is sent from tossing.Position at the socket joint mouth 3 of tossing is the position that is easy to generate obstruction most.The interface of bell mouth shape has not only strengthened the handling capacity of the tube of tossing, and the madial wall of inclination plays the effect of dredging to cereal kernel, has accelerated the speed of passing through of cereal kernel.
