Abstract

The utility model discloses an apron-type airless shot blasting machine, which comprises a shot blasting room. A rotary disk is respectively mounted on two side walls of an inner cavity of the shot blasting room; a drive roller is arranged at the rear upper part of the inner cavity of the shot blasting room, a large supporting roller is arranged at the rear lower part thereof, and a driven roller is arranged at the front lower part thereof; an apron with a convex corner and a blasting through hole is annularly formed on the drive roller is driven by a motor; the drive roller, the large supporting roller and the driven roller; a layer of apron between the drive roller and the driven roller envelopes partial arc sections of the disks to enable the apron between two disks to form an arc-shaped piece loading area. The apron-type airless shot blasting machine with the structure has the advantages that the apron is arranged in the shot blasting room used as a casing and is driven by the motor, so that the structure is simple, and the manufacture cost is low.

Description

Apron type airless shot blasting machine

Technical field

The utility model relates to a kind of sand removal equipment of foundry goods, is specifically related to a kind of apron type airless shot blasting machine.

Background technology

At present, the sand removal equipment of foundry goods mainly contains turntable type throwing pill machine and the convertible shot-blasting machine of crawler belt.The convertible shot-blasting machine of crawler belt is widely used because of its cleaning effect is good, be 02212359.8 as China Patent No. and be called to disclose a kind of shot-blasting machine in the patent document of " workpiece rotor crawler belt stands up the formula shot-blasting machine ", its primary structure is as follows: this shot-blasting machine comprises casing and cylinder, in cylinder, be provided with the crawler belt that is sleeved on the roll shaft, spiral conveying mechanism is established in the below of cylinder, one side of casing is provided with elevator, and the casing top is provided with impeller head and separator.The shot-blasting machine of said structure is provided with cylinder in casing, be provided with crawler belt in the cylinder, and cylinder and crawler belt be by different drive mechanism, complex structure, cost of manufacture height.

The utility model content

The technical problems to be solved in the utility model is at above-mentioned defective, provides a kind of cost of manufacture simple in structure low apron type airless shot blasting machine.

For solving the problems of the technologies described above, the utility model provides a kind of apron type airless shot blasting machine of following structure, comprise shot blast room, its design feature is: the disk that can rotate respectively is housed on the two side of shot blast room inner chamber, shot blast room inner chamber upper back is provided with drive roll, rear lower is provided with big carrying roller, preceding bottom is provided with driven voller, drive roll is by motor-driven, drive roll, big carrying roller and driven voller upper ring cap are provided with the crawler belt of protruding stupefied and ball sand via hole, and what one deck crawler belt envelope between drive roll and the driven voller made on the part segmental arc of disk that the crawler belt between two disks forms arcuation carries the part district.

The apron type airless shot blasting machine of said structure owing to only be provided with crawler belt in the shot blast room of double as casing, crawler belt by motor-driven, thereby simple in structure, cost of manufacture is low.

The foundry goods that spins upside down is bigger to the impact of crawler belt, crawler belt can produce bigger stretcher strain, has shortened the service life of crawler belt, in order to reduce the stretcher strain of crawler belt, prolong the service life of crawler belt, the inboard of the below of described disk, the envelope one deck crawler belt on disk is provided with little carrying roller.

Described crawler belt is a rubber belt track.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the left view of Fig. 1.

The specific embodiment

Apron type airless shot blasting machine as depicted in figs. 1 and 2, comprise shot blast room 1, the disk 2 that can rotate respectively is housed on the two side of shot blast room 1 inner chamber, shot blast room 1 inner chamber upper back is provided with drive roll 3, rear lower is provided with big carrying roller 4, preceding bottom is provided with driven voller 5, drive roll 3, big carrying roller 4 and driven voller 5 all are connected on the two side of shot blast room 1 and can rotate, drive roll 3 is driven by motor 6, drive roll 3, big carrying roller 4 and driven voller 5 upper ring caps are provided with protruding stupefied 8 and the crawler belt 7 of ball sand via hole 9, crawler belt 7 usefulness rubber are made, and one deck crawler belt 7 envelopes between drive roll 3 and the driven voller 5 are in year part district that makes the crawler belt 7 formation arcuations between two disks 2 on the part segmental arc of disk 2.The inboard of the below of described disk 2, the envelope one deck crawler belt 7 on disk 2 is provided with two little carrying rollers 10, and little carrying roller 10 is connected on the sidewall of shot blast room 1.In shot blast room 1 inner chamber, the below of crawler belt 7 is provided with sieves 11, and the below of screen 11 is provided with screw feeder 12, and the rear portion of shot blast room 1 is provided with elevator 13, is provided with shot-sand separator 14 and impeller head 15 at the top of shot blast room 1.Screw feeder 12, elevator 13, shot-sand separator 14 and impeller head 15 are prior art, do not repeat them here.

Its course of work of the apron type airless shot blasting machine of said structure is as follows: workpiece for clearance is placed on the crawler belt 7, start the machine, workpiece is driven by crawler belt 7 and do continuous upset in shot blast room 1, simultaneously, the bullet that impeller head is dished out at a high speed forms fan-shaped bullet bundle, hit equably on the surface of workpiece, thereby reach the purpose of cleaning, bullet and the sand grains that breaks away from from surface of the work, ball sand via hole 9 through evenly arranging on the rubber belt track flows on the screen 11 of shot blast room 1 bottom, screen 11 sifts out bigger particle, bullet and fine sand fall into the screw feeder 12 under the screen 11 and are sent into elevator 13 by screw feeder 12, bullet and fine sand are raised machine 13 and carry to shot-sand separator 14 and separating, dust is drawn in the bag-type dust by blower fan, the larger particles that is sifted out by the steel plate screen cloth of shot-sand separator 14, fail to separate completely that pill-sand mixture flows back to shot blast room 1 through the big stream material of waste material pipe, participate in separation again, isolated bullet flows into impeller head once more through stream ball pipe, restarts ball blast work.
