Description

Lower impact type gravel fills demonstrating model

Technical field

The utility model relates to a kind of demonstrating model, and a kind of lower impact type gravel of special design fills demonstrating model.

Background technology

It is a very important part at classroom teaching that gravel fills lower impact fill tool, in the filling process, utilizes the impulsive force of current to make gravel form hole, is now stretched in hole by oil pipe and can complete gravel filling process.Because working environment is in down-hole, a kind of simply and intuitively method can not allow classmate understand gravel clearly and fill lower ultimate principle of impacting fill tool now, is a part for comparatively difficulty in teachers ' teaching activity.So designing a kind of can the lower demonstrating model impacting fill tool of gravel filling intuitively be concisely necessary.

Summary of the invention

For the problems referred to above, the lower impact type gravel a kind of simple, directly perceived, easy to use of design fills demonstrating model.

The utility model solves the technical scheme that its technical matters adopts: it is by handle, oil pipe, gravel, sleeve pipe, oral siphon, rising pipe, tank, enter water pump and go out water pump composition, handle is loaded on oil pipe top, oral siphon one end is stretched in oil pipe, the other end with enter water pump and be connected and stretch in tank, sleeve pipe is placed in outside oil pipe, and gravel is filled in sleeve pipe, rising pipe one end is stretched among sleeve pipe, the other end with go out water pump and be connected and stretch in tank.

The utility model has the advantages that: simulation gravel that can be clear and intuitive fills the lower filling process impacting fill tool, and structure is simple, and easy and simple to handle, presentation process is clear, good demonstration effect.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is one-piece construction schematic diagram of the present utility model.

In Fig. 1,1. handle, 2. oil pipe, 3. gravel, 4. sleeve pipe, 5. oral siphon, 6. rising pipe, 7. tank, 8. enter water pump, 9. goes out water pump.

Embodiment

The utility model is by handle (1), and oil pipe (2), gravel (3), sleeve pipe (4), oral siphon (5), rising pipe (6), tank (7), enters water pump (8), goes out water pump (9) composition.During use, gravel (3) is put into sleeve pipe (4), enter water pump (8) work, the water in tank (7), by oral siphon (5), enters in oil pipe (2), and the gravel (3) impacting below form one can fuel feed pump (2), the poroid region stretched into, now can press down handle (1) and oil pipe (2) is stretched into, and goes out water pump (9) work, superfluous water flows in tank (7) again through rising pipe (6), completes gravel filling process.This device has easy and simple to handle, the feature of good demonstration effect.
