A kind of rapeseed thresher
Technical field
The invention belongs to the farm machinery technical field, is a kind of rapeseed thresher specifically.
Background technology
China is not only as the first in the world populous nation, it is also world food big country always, cereal, vegetables, the demand of oil crop is always very huge, rape is as one of main edible oil raw material of China, and that yes is very considerable for cultivated area and output, is singly that the output of 2012 just reaches 1,280 ten thousand tons.But the threshing course after rape dries is the process of one complexity always, large output relatively like this, manually-operated workload is just well imagined.Therefore a kind ofly can carry out semi-finished machine to rape and just seem and extremely need.
Summary of the invention
The purpose of this invention is to provide the enough machine of a kind of energy and replace manual operations to carry out threshing, screening to rape, and the semi-finished equipment of rape to having gathered in the crops and having dried.
The objective of the invention is to be achieved through the following technical solutions:
A kind of rapeseed thresher, comprise circular housing, bearing frame and upper cover, described circular housing is fixed on described bearing frame, described upper cover covers on circular housing, on cover and be provided with hole, this rapeseed thresher also comprises driving link, follower lever, axis, turbine, worm screw and baffle plate, described baffle plate is radially erect and is fixed on described bearing frame outer ring, described bearing frame center and upper cover center are equipped with the bottom bracket bearing seat of the fixing described axis in location, described driving link is the connected several rod members of cutting oblique arrangement that are in bottom, be sleeved on described axis lower end, described axis can drive described driving link by the key transmission and rotate, described follower lever is fastened on the rod member of driving link by torsion spring, follower lever can the auto-returned original position after swinging.Described axis is by turbine and worm mechanism transmission power, described turbine is arranged on the axis upper end, described worm screw is fixed by being arranged on worm shaft bearing corresponding on described circular housing, external motor is placed on contour shelf, electrical axis and power shaft level, and both connect with shaft coupling, the supporting leg root of described bearing frame is with removable screen cloth, because removable screen cloth has elasticity, slight curving removable screen cloth utilizes elastic card between the supporting leg of bearing frame, installs, dismantles easily.
To further improvement of the present invention, the rod member quantity on driving link is three, is mutually 120 and cuts oblique arrangement, and the follower lever on every rod member is 4.
To further improvement of the present invention, cover on described and be provided with clamping plate, an end chain connection is in the upper cover center, cover on described and also be provided with spring hangering nail, clamping plate can rotate upper covering, and spring hangering nail tangles spring, the spring other end catches on clamping plate, makes clamping plate that a clamping force be arranged.
To further improvement of the present invention, the supporting leg of described bearing frame is provided with the film hook of hanging film, and the film hook is positioned at described removable screen cloth below.
To further improvement of the present invention, described follower lever adopts the softer plastics of material or rubber as material.
The present invention has following outstanding beneficial effect: imitate the process of manual operation threshing, use machine instead and realized, replace pure hand labour, save time, raise the efficiency laboursaving workload.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As Fig. 1, Fig. 2, shown in Fig. 3, rapeseed thresher comprises circular housing 1, bearing frame 8 and upper cover 2, circular housing 1 is fixed on bearing frame 8, upper cover 2 covers on circular housing 1, upper cover 2 is provided with hole 3, upper cover 2 is provided with clamping plate 4, one end chain connection is in upper cover 2 centers, also be provided with spring hangering nail 6 on upper cover 2, clamping plate 4 can rotate on upper cover 2, spring hangering nail 6 tangles spring, the spring other end catches on clamping plate 4, make clamping plate 4 have this rapeseed thresher of clamping force also to comprise driving link 15, follower lever 14, axis 11, worm gear 10, worm screw 11 and baffle plate 9, baffle plate 9 is radially erect and is fixed on bearing frame 8 outer rings, bearing frame 8 centers and upper cover 2 centers are equipped with the fixedly bottom bracket bearing seat 5 of axis 11 of location, driving link 15 is for bottom is connected several rod members 16 of cutting oblique arrangement, be sleeved on axis 11 lower ends, axis 11 can drive driving link 15 by the key transmission and rotate, rod member 16 quantity on driving link 15 are three, be mutually 120 and cut oblique arrangement, follower lever 14 on every rod member 16 is 4, follower lever 14 adopts the softer rubber of material as material, follower lever 14 is fastened on the rod member 16 of driving link 15 by torsion spring, can the auto-returned original position after follower lever 14 swings.Axis 11 is by worm-and-wheel gear transmission power, worm gear 10 is arranged on axis 11 upper ends, worm screw 12 is fixed by being arranged on worm shaft bearing 13 corresponding on circular housing 1, the supporting leg root of bearing frame 8 below bearing frames 8 is with removable screen cloth 7, the supporting leg of bearing frame 8 is provided with the film hook 17 of hanging film, and film hook 17 is positioned at removable screen cloth 7 belows.External motor is placed on contour shelf, electrical axis and power shaft level, and both connect with shaft coupling.
In conjunction with Fig. 1, Fig. 2, before threshing, on the film hook 17 below machine, hang up thin film, be used for collecting vegetable seed.Putting rear threshing well starts, the vegetable seed root is put into machine outwardly, spring is hooked to the clamping plate 4(spring other end fixing by spring hangering nail 6), clamping plate 4 can be fixed the rape root, open motor, the machine entry into service, drive axis 11, driving link 15 rotations, and follower lever 14 is patted and is positioned at the rape cotyledon in casing in the process around axis 11 rotations, vegetable seed after drying comes off after patting from cotyledon, wherein, baffle plate 9 mainly plays the positioning action of rape, prevents that the stressed rear generation of rape from moving.After vegetable seed falls down, through the screening of the removable screen cloth 7 of bearing frame 8 attached below, fall in the film of machine below and collect, so far threshing course completes.Simultaneously, removable screen cloth 7 can disassemble after work completes, and is maintained and sweeps.
Be more than preferred embodiment of the present invention, all changes of doing according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
