The shot blasting machine is arranged on the vibration groove grid to perform shot blasting cleaning on the casting, so that no problem exists, and if the bottom of the casting cannot be shot blasted or the casting cannot be turned over, the cleaning quality of the casting cannot meet the requirement at all. In 1980, the inventor takes part in an experimental study of a vibration groove passing type shot blasting machine which vibrates transversely in the research institute of the Jinan casting and forging machinery, which is the department of the mechanical industry, the transverse vibration aims at turning over a casting on the side wall of a groove body, and a shot blasting device is only arranged on the upper part of the groove body, but is finally aborted because of the unsatisfactory turning over effect of the casting.

The central lines of the two vibrating conveying grooves are in the same longitudinal straight line, the tail end of the first vibrating conveying groove (namely the front vibrating conveying groove 1) and the starting end of the second vibrating conveying groove (namely the rear vibrating conveying groove 11) are arranged in a staggered manner up and down at the central position of the shot blasting chamber, and a casting turns over or falls into the rear vibrating conveying groove 11 from the front vibrating conveying groove 1 at the position, so that the uniformity of shot blasting quality can be further improved; the front vibration conveying groove 1 is divided into a vibration shakeout section and a shot blasting cleaning section, and the rear vibration conveying groove 11 is divided into a shot blasting cleaning section and a shot recycling section; the front and the back vibration conveying groove parts in the shot blasting chamber jointly form a shot blasting cleaning section. The arrangement of the double vibrating conveying grooves with the fall provides the casting with the opportunity of turning over or changing the posture once, and the casting falls into the vibrating conveying groove 11 at the back so as to further improve the uniformity of shot blasting quality. As shown in figure 1, 8 impeller heads 4 are arranged on the upper surface and the lower surface of the impeller head chamber, 4 impeller heads are arranged on the upper part 3 of the impeller head chamber, and 4 impeller heads are arranged on the lower part 9 of the impeller head chamber. The arrangement of the impeller head 4 fully considers that six surfaces of the casting are shot blast, and the casting is turned over or not turned over when rolling down between the front and rear vibrating conveying

grooves

1 and 11.

The shot blasting chamber is divided into an upper part and a lower part, the upper part and the lower part are connected into a whole through a connecting piece, and the upper part and the lower part are designed for convenient installation, maintenance and transportation; the number of the impeller heads arranged on the upper part and the lower part is basically equal, and the impeller head chambers on the upper part and the lower part are all formed by directly welding wear-resistant steel plates.

The vibration shakeout section is an exposed part of the front vibration conveying groove in front of the shot blasting chamber, and is divided into an upper layer and a lower layer, wherein the upper layer is a grid and is used for impacting casting shakeout and conveying the casting; the lower layer is a steel plate and is used for conveying sand, nails, flashes, burrs and the like falling from the upper layer, when the casting is molded by sand casting, a large amount of sand, nails, flashes, burrs and the like which impact the casting and fall into the lower layer are transversely conveyed out by falling into the belt conveyor 16 from an outlet at the lower end of the section, and at the moment, the casting is provided with a small amount of sand after vibrating and falling; when the casting is molded by non-sand casting, the section directly conveys the upper-layer falling objects to a pit funnel at the lower part of the shot blasting chamber.

The belt conveyor 16 is transversely arranged, is crosswise arranged with the vibration conveying trough and is positioned at the lower part of the tail end of the steel plate of the vibration shakeout section.

The shot recovery section is an exposed part of the rear vibration conveying groove behind the shot blasting chamber, and is divided into an upper layer and a lower layer, wherein the upper layer is a grid and is used for conveying castings after sand falling and shot blasting cleaning and shaking off residual shots in uncomplicated inner cavities of the castings; the lower layer is a steel plate and is used for conveying the shot falling from the upper layer to the bottom outlet at the tail end part of the vibration conveying groove and conveying the shot to the pit hopper at the lower part of the shot blasting chamber by the screw conveyor 12 at the lower part of the steel plate.

The grid 15 with the corresponding structure for shot blasting comprises a grid frame 1501, transverse partition plates 1502 and longitudinal partition plates 1503 in the grid frame 1501, gaps among the transverse partition plates 1502 are matched with the scattering angles beta of shots in the width direction of impeller blades of the shot blasting devices 4 when the shot blasting devices 4 corresponding to the lower parts of shot blasting cleaning sections are thrown, and the transverse partition plates are designed corresponding to the shot flow scattering angles beta in the width direction of the blades, namely the two transverse partition plates are arranged on the front side and the rear side of shot flow thrown by the shot blasting devices.

When the longitudinal partition 1503 and the impeller head 4 corresponding to the lower part of the shot blasting cleaning section are cast, the jet directions of all the shots in the fan-shaped angle alpha range of the impeller blade circumference direction of the impeller head 4 are matched. Each partition plate is designed according to different angles, the longitudinal partition plates meet the requirement of normal conveying of castings on the upper portion of the grid and correspond to the alpha angle of shot jet flow of the shot blasting device on the lower portion, the size of the alpha angle is determined by setting of a window of a directional sleeve of the shot blasting device, the direction of the flying angle of each shot in the range of the alpha angle is different, but the flying angle of each shot in the range of the alpha angle follows a certain movement law, and therefore the design angle corresponding to each longitudinal partition plate in the area also follows the shot flying direction of the movement law. The three parts of the corresponding structure grid 15 for shot blasting can be welded parts formed by wear-resistant steel plates or wear-resistant steel castings.

The construction of the corresponding structural grid 15 for shot blasting makes it possible for the shot blasters 4 arranged below the vibrating conveyor to project the shot through this section with only a small resistance, so that the quality of the shot blast on the upper and lower sides of the cleaned casting is substantially the same. The ejection principle of the impeller head 4 is that the jet direction of each shot refers to the jet direction of all the shots within the range of the scattering angle beta formed by the shot in the width direction of the impeller blade of the impeller head and the fan-shaped scattering angle alpha of the impeller blade of the impeller head in the circumferential direction when the impeller head ejects the shot. The thickness of the longitudinal partition 1503 is gradually reduced from top to bottom, the upper thickness is that the longitudinal partition needs to have enough strength for impacting and conveying the casting, the lower thickness is used for reducing resistance and guiding flow of flying shots, and the lower thickness also needs to keep enough strength for resisting impact of shot-throwing.

The dust removal port of the dust removal system 10 is arranged on the dust removal sealing cover 2 of the vibration conveying groove outside the shot blasting chamber, and can remove dust of falling sand and shot blasting simultaneously.

When the device is applied, a casting to be treated falls on a shakeout section of the front vibration conveying groove 1 and is conveyed by the vibration conveying groove in a vibration mode, a grid on the upper layer of the shakeout section impacts shakeout of the casting and conveys the casting to move forward, and sand, iron nails, flash, burrs and the like which fall on the casting due to impact fall on a steel plate on the lower layer; when the casting is molded by sand casting, the section of the casting is used for impacting a large amount of sand, iron nails, flash, burrs and the like falling into a lower layer, and the casting falls into the belt conveyor 16 from an outlet at the lower end part of the section and is transversely conveyed out, and at the moment, the casting is provided with a small amount of sand after shaking and shakeout; when the casting is cast in a non-sand mode, the upper-layer falling objects are directly conveyed to a pit funnel at the lower part of the shot blasting chamber by the section.

The castings after shakeout are conveyed to a shot blasting cleaning section of a shot blasting chamber by a vibration conveying groove to be shot-blasted, and the section only has an upper grid and no lower steel plate and is specially designed for facilitating shot blasting of a bottom shot blasting device. When the casting passes through the designed grid 15 with the corresponding structure for shot blasting, the shot blasting devices 4 at the lower part 9 of the shot blasting chamber can perform shot blasting on the casting except the shot blasting devices 4 at the upper part 3, so that the shot blasting devices 4 arranged below the vibration conveying grooves can only bear small resistance when penetrating through the grid structure, and the shot blasting quality of the upper part and the lower part of the cleaned casting is basically the same.

vibration conveying grooves

1 and 11 outside the shot blasting chamber, and can remove dust from falling sand and shot blasting simultaneously.

Example 2:

fig. 2 shows a scheme of a single-vibration conveying trough with 4 impeller heads, which is different from the scheme of the embodiment 1 in that the scheme is completely the same as the scheme of the embodiment 1 except that the casting in the scheme of the embodiment 1 can turn over when falling from a front vibration trough and a rear vibration trough and the arrangement of 4 impeller heads is reduced.

The arrangement of the 4 shot blasting machines also fully considers the design that the shot blasting cleaning can be carried out on six surfaces of the casting. Belonging to simplified versions aiming at different user requirements.
