Description

A kind of teaching mode machine

Technical field

This application involves a kind of model, the teaching mode machine of the related scraper teaching of especially a kind of vocational school.

Background technique

As our countries increasingly pay attention to vocational education, major special professional colleges are to teaching mould needed for vocational education The demand of type machine is also more more and more urgent, can intuitively demonstrate the prototype of scraper scraper soil principle, is the needs of students.

Summary of the invention

Present applicant proposes the teaching mode machines that one kind can intuitively demonstrate scraper scraper soil principle.

The application is achieved by the following technical solution:

A scraper bowl, shovel is arranged in a kind of teaching mode machine, including draw bar, shafts frame, front-wheel, rear-wheel between front-wheel and rear-wheel Bucket is rectangle, and scraper bowl is made of two pieces of side plates of sluice gate, back plate, bottom plate and front and back, its special feature is that: under sluice gate Portion digs a rectangle hole, installs a scraper wheel in rectangle hole.

The scraper wheel includes axis, the cam for being fixed on axis and the torus being able to rotate.

Sluice gate is fixed at the both ends of the axis, and the centre of axis is fixed with cam, and front and back two is arranged in also rotation on axis A axle sleeve.

One of arc groove is arranged in the border of the cam.

The torus covers on cam, and torus is using axis as axle center.

Multiple square holes are equidistantly dug on the torus, and a movable blades are set in each square hole.

An arc head is arranged by one end of cam in the movable blades, and arc head is slidably arranged in arc groove, described Blade is arranged in the other end of movable blades.

The front of the torus is fixed on an axle sleeve of front by two connecting rods of front, after the torus An axle sleeve at rear portion is fixed in portion by two connecting rods at rear portion.

The application has the advantages that

Present applicant proposes the teaching mode machines that one kind can demonstrate scraper scraper soil principle.

Detailed description of the invention

The application is further described with reference to the accompanying drawing:

Fig. 1 is the structural schematic diagram of the application；

Fig. 2 is the drawing of Fig. 1 scraper wheel；

Fig. 3 is A-A view of Fig. 2；

Fig. 4 is B-B view of Fig. 2；

Fig. 5 is C-C view of Fig. 2；

Fig. 6 is D-D view of Fig. 2.

In figure: a scraper wheel, 1 draw bar, 2 front-wheels, 3 shafts framves, 4 sluice gates, 5 back plates, 6 tailstocks, 7 rear-wheels, 8 knives Shovel, 9 bottom plates, 10 cams, 11 axis, 12 torus, 13 square holes, 14 movable blades, 15 axle sleeves, 16 connecting rods, 17 circles Arc slot, 18 arc heads.

Specific embodiment

Attached drawing is a kind of embodiment of the application, which includes draw bar 1, shafts frame 3, front-wheel 2, rear-wheel 7, in front-wheel One scraper bowl is set between rear-wheel, scraper bowl is rectangle, scraper bowl by sluice gate 4, back plate 5, bottom plate 9 and front and back two pieces of side plate groups At, its special feature is that: a rectangle hole is dug in the lower part of sluice gate, a scraper wheel is installed in rectangle hole.

The scraper wheel includes axis 11, the cam 10 for being fixed on axis and the torus 12 being able to rotate.

Sluice gate 4 is fixed at the both ends of the axis 11, and the centre of axis is fixed with cam 10, before also rotating setting on axis Latter two axle sleeve 15.

One of arc groove 17 is arranged in the border of the cam 10.

For 12 sets of the torus on cam 10, torus 12 is axle center with axis 11.

Multiple square holes 13 are equidistantly dug on the torus 12, and a movable blades 14 are set in each square hole 13.

An arc head 18 is arranged by one end of cam in the movable blades 14, and arc head 18 is slidably arranged in arc groove 17 Interior, blade is arranged in the other end of the movable blades 14.

The front of the torus 12 is fixed on an axle sleeve 15 of front, the annulus by two connecting rods 16 of front An axle sleeve 15 at rear portion is fixed at the rear portion of body 12 by two connecting rods 16 at rear portion.

The torus 12 is fixedly arranged at the front end with gear ring, and gear ring is engaged in a gear, and gear is driven by driving machine.

In the application use process, prototype is pulled by draw bar, while starting driving machine, driving machine is just with moving gear Rotation, gear drive torus to rotate counterclockwise using axis as axle center by the gear ring of engagement, multiple movable blades on torus Piece enters mamoty in scraper bowl.

Due to the effect of cam, when movable blade slice bar soil, stretches out, and retracts in movable blades to scraper bowl.

With the rotation of torus, arc head is slided in arc groove.

Positional relationship described herein is described in the positional relationship with Fig. 1, Fig. 2.
