Description

Technical Field

[0001] This utility model relates to the technical field of cast iron pipe production equipment, and in particular to a sand distribution device with a cleaning function. Background Technology

[0002] Before casting cast iron pipes, sand needs to be spread in the pipe mold of the centrifuge; after casting is completed and the pipes are put away, the pipe mold of the centrifuge needs to be cleaned.

[0003] The current sand distribution device involves manually rotating a wheel to turn the sand distribution pipe 180° and pour sand into the mold. This manual rotation results in low production efficiency. Furthermore, the current device can only distribute sand; cleaning the mold requires manual labor using a long-handled scraper, which is close to the centrifuge mold, leading to low efficiency, high labor intensity, and reliance on manual experience for cleaning effectiveness. Manual cleaning also requires standing at the mold opening, where the high ambient temperature poses a risk of injury and compromises safety. Installing a separate cleaning device would require more space and increase equipment costs. Utility Model Content

[0036] like Figure 1-4 As shown in the figure, the present invention provides a sand-spreading device with cleaning function, including: a sand tank support frame 10, a sand tank 2 and a sand-spreading trolley 7.

[0037] The sand jar 2 is movably mounted on the sand jar support frame 10. Specifically, a sand jar trolley moving track is arranged on the sand jar support frame 10. The sand jar 2 and the screw motor 3 are mounted on the sand jar trolley 8. The sand jar 2 is movably mounted on the sand jar trolley moving track via the sand jar trolley 8. A sand jar moving motor 11 is installed on the sand jar trolley 8. Sand jar trolley wheels are installed at the four corners of the sand jar trolley 8, and the sand jar trolley wheels are driven by the sand jar moving motor 11, enabling the sand jar trolley 8 to move the sand jar 2 and its components. A ladder is installed at the end of the sand jar support frame 10.

[0038] The sand jar 2 has a sand inlet at its top and a sand outlet at its bottom. A auger 1 is positioned below the sand jar 2. The auger 1 is perpendicular to the length of the sand jar support frame 10. The auger 1 is connected to the output shaft of the auger motor 3. One end of the auger 1 has a auger inlet, and the other end has a auger outlet. The auger inlet connects to the sand jar outlet. The auger motor 3 drives the auger 1 to rotate, thus outputting sand and gravel.

[0039] The sand-spreading trolley 7 is movably mounted on one side of the sand tank support frame 10. The sand-spreading trolley 7 is equipped with a U-shaped groove 4, support arms 5, hydraulic rods 6, and cleaning brushes 9. A tilting motor 13 and a support arm shaft 17 are mounted on the top of the sand-spreading trolley 7. There are two support arms 5, with a connecting plate 20 between them. One end of each support arm 5 is movably mounted on the support arm shaft 17, and the other end is movably mounted on the U-shaped groove 4. The cleaning brush 9 is fixedly mounted at the bottom of the U-shaped groove 4. The tilting motor 13 is connected to the U-shaped groove 4 via a sprocket and chain mechanism. Through the tilting motor 13 and the sprocket and chain mechanism, the U-shaped groove 4 can be rotated 180° to empty the sand and gravel from the U-shaped groove 4.

[0040] The support arm 5 is connected to the U-shaped groove 4 via a connecting rod 21. Specifically, a bearing is provided at the end of the support arm 5, and the bearing is sleeved on the connecting rod 21, which is fixed to the U-shaped groove 4; the connecting rod 21 can rotate within the bearing. The sprocket and chain mechanism includes: a first sprocket 14, a second sprocket 15, a third sprocket 16, a first chain 18, and a second chain 19; the first sprocket 14 is located at the output end of the flip motor 13; the second sprocket 15 is located on the support arm 5 near the flip motor 13; the third sprocket 16 is located at the end of the connecting rod 21; the first sprocket 14 and the second sprocket 15 are connected by the first chain 18; the second sprocket 15 and the third sprocket 16 are connected by the second chain 19. The second sprocket 15 can be a coaxial double sprocket. When the flip motor 13 rotates, the sprocket and chain mechanism can drive the connecting rod 21 and the U-shaped groove 4 to rotate.

[0041] The hydraulic rod 6 is hinged to the sand-distributing trolley 7, and the telescopic end of the hydraulic rod 6 is hinged to the connecting plate 20. By extending and retracting the telescopic rod 6, the connecting plate 20 and the two support arms 5 can rotate circumferentially around the support arm axis 17, thus lifting and lowering the U-shaped channel 4. When the U-shaped channel 4 is lifted into position, it is located directly below the screw rod outlet.

[0042] Based on the above scheme, a sand-spreading trolley track is arranged on one side of the sand tank support frame 10, and the sand-spreading trolley 7 is movably mounted on the sand-spreading trolley track. A sand-spreading trolley moving motor 12 is installed on the sand-spreading trolley 7; sand-spreading trolley wheels are installed at the four corners of the sand-spreading trolley 7, and the sand-spreading trolley wheels are driven by the sand-spreading trolley moving motor 12 to realize the movement of the sand-spreading trolley 7.

[0043] A compressed air pipe is arranged on the U-shaped groove 4; the air inlet of the compressed air pipe is connected to an air compressor, and the air outlet of the compressed air pipe is close to the cleaning brush 9. The compressed air pipe can spray compressed air, which can blow air while the cleaning brush 9 is cleaning.

[0044] The working process of the sand distribution device with cleaning function of this utility model is as follows: the sand distribution trolley 7 and the sand tank trolley 8 retract to the rear limit position, the hydraulic rod 6 extends, and the support arm 5 is lifted (e.g., Figure 3 (As shown in the diagram), keep the container close to the screw discharge port, with the U-shaped trough 4 opening upwards and below the screw discharge port; the screw motor 3 starts, pushing the sand and gravel in the sand hopper 2 into the U-shaped trough 4 via the screw 1. Simultaneously, the sand hopper moving motor 11 starts, moving the sand hopper 2 forward to the front limit position. At this point, the U-shaped trough 4 is full of sand and gravel, and the sand discharge is complete.

[0045] Before centrifuge casting, retract hydraulic rod 6 and lower support arm 5 (as shown). Figure 2(As shown in the diagram). At this point, the sand-spreading trolley movement motor 12 starts, moving the sand-spreading trolley 7 forward to the front limit position. At this time, the U-shaped groove 4 is completely inside the centrifuge tube mold. The tilting motor 13 starts, and the U-shaped groove 4 slowly rotates 180°, pouring the sand and gravel in the U-shaped groove 4 into the centrifuge tube mold. After pouring, the tilting motor 13 rotates in the opposite direction to reset the U-shaped groove 4. The sand-spreading trolley movement motor 12 moves the sand-spreading trolley 7 backward to the rear limit position. The hydraulic rod 6 extends to lift and hold the support arm 5, and the sand-spreading process ends.

[0046] After the centrifuge tube removal is completed, the hydraulic rod 6 retracts, the support arm 5 remains in the lowered position, the sand-spreading trolley movement motor 12 starts, and the sand-spreading trolley 7 moves forward slowly. While the tube mold rotates, the cleaning brush 9 and compressed air pipe clean the inner wall of the tube mold. When the sand-spreading trolley 7 reaches the front limit position, it slowly retracts until it reaches the rear limit position and stops. At this point, the hydraulic rod 6 raises the support arm 5 to its position, and the cleaning is complete.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
