Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Precoated sand core making machine feed system described in the utility model, as shown in Figure 1, comprise one-level storage bin hopper 1, secondary storage bin hopper 2, core making machine feed hopper 8 and conveying mechanism, one-level storage bin hopper 1 is less than secondary storage bin hopper 2 apart from ground level apart from ground level, and secondary storage bin hopper 2 is less than core making machine feed hopper 8 apart from ground level apart from ground level;
Conveying mechanism comprises conveyer mechanism for carrying out between one-level storage bin hopper 1 and secondary storage bin hopper 2 carrying, for carrying out the auger 7 carried between secondary storage bin hopper 2 and core making machine feed hopper 8.
Because core making machine feed hopper 8 is large apart from ground level, if adopt first-level transport mechanism, no matter be adopt conveyer mechanism, or adopt auger 7, all there is delivery stroke long, required drive consumes huge, be unfavorable for holistic cost saving, carry the shortcoming of poor effect simultaneously.Based on this, this precoated sand core making machine feed system have employed the mode of operation of two-stage delivery mechanism, during work, first precoated sand is poured into the minimum one-level storage bin hopper 1 in position, by conveyer mechanism, precoated sand is delivered in secondary storage bin hopper 2 again, again through auger 7, the precoated sand in secondary storage bin hopper 2 is delivered in core making machine feed hopper 8, complete the conveying of precoated sand core making machine raw material and reinforced work.
Above-mentioned for carrying out the conveyer mechanism carried between one-level storage bin hopper 1 and secondary storage bin hopper 2, concrete, comprise conveyer belt 3, driving wheel 4 and follower 5, secondary storage bin hopper 2 two opposite sides plate upwards extends to form follower bracing frame 9, be fixed with follower back shaft 12 between follower bracing frame 9, follower back shaft 12 is provided with two followers 5 by bearing;
Be provided with by bearing the drive roll 13 paralleled with follower back shaft 12 bottom one group of opposite flank of one-level storage bin hopper 1, drive roll 13 fixedly mounts two driving wheels 4, and driving wheel 4 is connected by conveyer belt 3 with follower 5.
During work, rotated by driven by motor drive roll 13, and then drive driving wheel 4 to rotate, thus conveyer belt 3 is moved, the precoated sand in one-level storage bin hopper 1 is transported to secondary storage bin hopper 2.
Further, as shown in Figure 2, described conveyer belt 3 is installed with some link plates 6 on the surface, conveyer belt 3 surface is separated out some little lattice by link plate 6, and when conveyer belt 3 moves, link plate 6 can play the effect of similar scoop, precoated sand in one-level storage bin hopper 1 is brought in little lattice, in course of conveying, link plate 6 also plays the effect stoping precoated sand unrestrained, improves transfer efficiency.
Further, in order to farthest play in course of conveying, stop the effect that precoated sand is unrestrained, described link plate 6 is perpendicular with conveyer belt 3, equal fabric belt 3 surface.
Further, described secondary storage bin hopper 2 has holding tank 10, holding tank 10 is positioned at the below of the conveyer belt 3 that secondary storage bin hopper 2 is installed, and prevents the link plate 6 on conveyer belt 3 and the scratching of secondary storage bin hopper 2 sidewall.
For carrying out the auger 7 the carried transportation scheme as maturation between secondary storage bin hopper 2 and core making machine feed hopper 8, its structure and working principle the utility model is not specifically addressed, described auger 7 charging aperture is positioned at bottom secondary storage bin hopper 2, and discharging opening is positioned at above core making machine feed hopper 8.
Concrete, in order to more convenient be that one-level storage bin hopper 1 feeds in raw material, described one-level storage bin hopper 1 is arranged on ground, and the secondary storage bin hopper 2 highly higher than one-level storage bin hopper 1 is arranged on brace table 11.
Further, described one-level storage bin hopper 1 is in rectangular-shaped structure, two driving wheels 4 that drive roll 13 is installed, lay respectively at two ends that drive roll 13 is positioned at one-level storage bin hopper 1 part, can ensure like this one-level storage bin hopper 1 along the width of drive roll 13 length direction and conveyer belt 3 width basically identical, prevent the precoated sand in one-level storage bin hopper 1 to be distributed in outside conveyer belt 3, play the object improving transfer efficiency.
In order to further improve transfer efficiency, the one end being provided with two grade bars 14, two grade bar 14 in described one-level storage bin hopper 1 is located at respectively and is not installed on one group of opposite flank of drive roll 13;
The other end of two grade bars 14 is all located at bottom one-level storage bin hopper 1, and one is positioned at drive roll 13 front, and one is positioned at drive roll 13 rear.The setting of grade bar 14, within the precoated sand in one-level storage bin hopper 1 can be made to concentrate on scope that conveyer belt 3 and link plate 6 can reach.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
