Description

A kind of sand leakage mechanism of penetrating sand machine
Technical field
The present invention relates to penetrating sand machine fields, particularly relate to a kind of sand leakage mechanism of penetrating sand machine.
Background technique
Sand leakage mechanism is a kind of important operating mechanism in penetrating sand machine, and sand leakage mechanism, which is mounted on, penetrates between sand hopper and hopper, It is mainly used for controlling hopper and penetrates sand and air on-off between sand hopper, but existing sand leakage mechanism structure is many and diverse, it has not been convenient to pacifies Dress, in the work of sand leakage mechanism, air-tightness is poor, influences its control effect.
Summary of the invention
The present invention to solve problems of the prior art, proposes a kind of sand leakage mechanism of penetrating sand machine.
The technical scheme of the present invention is realized as follows:
A kind of sand leakage mechanism of penetrating sand machine, composition include: cylinder and the cylinder block for fixing the cylinder, and the cylinder is logical It crosses stay bolt to be fixed on cylinder block, is equipped with flange in the bottom of the cylinder block, is equipped with ring at the downside of the flange inner hole Shape protrusion, the cylinder block are the cylindrical structure with cavity, and the feed pipe communicated therewith is equipped in the side of the cylinder block, A piece screw rod is inserted into the cavity of the cylinder block, and is connect with the piston rod internal thread of the cylinder, the lower part of the screw rod It is respectively equipped with rubber gasket and cylindrical tube with middle part, the rubber gasket is located at the lower section of the annular protrusion.
The piston rod of the cylinder is deep into the cavity of the cylinder block and connect with the screw rod internal thread.
Several fixation holes are additionally provided on the flange.
The diameter of the rubber gasket is greater than the diameter of the annular protrusion, and the rubber gasket is fixed by nut On the screw rod.
The beneficial effects of the present invention are: the configuration of the present invention is simple is compact, the annular protrusion on flange inner hole and screw rod lower part Rubber gasket can be very good to close sand losing opening, sealing effect is more preferable, prevents sand leakage.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with It obtains other drawings based on these drawings.
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is main view of the invention;
Fig. 3 is the structural schematic diagram of screw rod and cylinder;
Fig. 4 is the structural schematic diagram of flange.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor Embodiment shall fall within the protection scope of the present invention.
A kind of sand leakage mechanism of penetrating sand machine as shown in Fig. 1 ~ Fig. 4, composition includes: cylinder 1 and the gas for fixing cylinder 1 Cylinder seat 3, cylinder block 3 are the cylindrical structure with cavity, and the feed pipe 2 communicated therewith, cylinder 1 are equipped in the side of cylinder block 3 It is fixed on cylinder block 3 by the side wall that stay bolt passes through cylinder block 3, flange 4 is equipped in the bottom of cylinder block 3, in flange 4 Center is equipped with flange inner hole 5, and annular protrusion 6 is equipped at the downside of flange inner hole 5, and flange inner hole 5 is sand losing opening, a screw rod 7 It is inserted into the cavity of cylinder block 3, and is connect with 8 internal thread of the piston rod of cylinder 1, the lower part and middle part of screw rod 7 are respectively equipped with rubber Glue gasket 9 and cylindrical tube 10, rubber gasket 9 are fixed on screw rod 7 by nut, are also had in cylindrical tube 10 and are revolved with screw rod 7 Tight internal screw thread, rubber gasket 9 are located at the lower section of annular protrusion 6, and the diameter of rubber gasket 9 is slightly larger than annular protrusion 6 Diameter enables rubber gasket 9 to close flange inner hole 5.
The piston rod 8 of cylinder 1 is deep into the cavity of cylinder block 3 and connect with 7 internal thread of screw rod.
It is additionally provided with several fixation holes 11 on flange 4, flange 4 is fixed on by the fixation hole 11 and is penetrated on sand hopper.
In mechanism, sand enters in cylinder block 3 from feed pipe 2, when sand enters in cylinder block 3, cylinder 1 It opens, lead-screw 7 moves downward, so that rubber gasket 9 is separated with the annular protrusion 6 on the sand losing opening at 4 middle part of flange, After the two separation, sand is entered from leakage in sand losing opening and is penetrated in sand hopper;When not needing sand into when penetrating sand hopper, cylinder 1 is closed It closes, rubber gasket 9 rises and fits closely with the annular protrusion 6 on flange inner hole 5, and such sand would not be from flange inner hole 5 leak into and penetrate sand hopper and suffer;When cylinder is turned on or off, cylindrical tube 10 is moved up and down, and the speed of sand leakage can be improved And prevent sand from accumulating.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
