Sand mixer with dust removal function for production of rockers

Abstract

This utility model discloses a sand mixer with dust removal function for bolster production, including a worktable. A dual-axis motor is fixedly connected to the central shaft at the bottom of the worktable, and a crankshaft is fixedly connected to the bottom of the dual-axis motor. A housing is provided on one side of the worktable, and a horizontal plate is provided at the central shaft of the inner cavity of the housing. The inner cavity of the horizontal plate is movably connected to the crankshaft, and sealing plates are fixedly connected to both sides of the horizontal plate. The dual-axis motor drives the crankshaft to rotate, which in turn moves the horizontal plate, which in turn moves the sealing plates. As the sealing plate moves to the right, dust is drawn in through the air guide pipe, corrugated pipe, and suction head on the left side, causing the dust to enter the hollow block cavity on the left. Similarly, as the horizontal plate moves to the left, dust is drawn in through the air guide pipe, corrugated pipe, and suction head on the right side, causing the dust to enter the hollow block cavity on the right. The dust is then filtered out by a filter plate.

Description

Technical Field

[0001] This utility model relates to the field of bolster production technology, specifically to a sand mixer with dust removal function for bolster production. Background Technology

[0002] In the manufacturing process of rocker bolsters, the sand mixing stage is crucial, playing a decisive role in the quality of the molding sand and thus profoundly affecting the quality of the bolster castings. With the development of the manufacturing industry, the production scale of rocker bolsters continues to expand, and the requirements for production efficiency and product quality are becoming increasingly stringent.

[0003] Traditional sand mixers have many problems that need to be solved during operation. During the sand mixing process, the frequent friction and tumbling between sand particles generates a large amount of dust. This dust spreads freely in the production workshop, causing the air quality in the workshop to deteriorate sharply. Long-term exposure to such an environment greatly increases the probability of workers suffering from respiratory diseases, such as pneumoconiosis. To address this, we propose a sand mixer with dust removal function for bolster production. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a sand mixer with dust removal function for bolster production. This dust removal function solves many problems that need to be addressed in the operation of traditional sand mixers. During the sand mixing process, frequent friction and tumbling between sand particles generate a large amount of dust. This dust permeates the production workshop, causing a sharp deterioration in air quality. Prolonged exposure to such an environment significantly increases the probability of workers contracting respiratory diseases, such as pneumoconiosis.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand mixer with dust removal function for bolster production, comprising a workbench, a dual-axis motor fixedly connected to the central shaft at the bottom of the workbench, a crankshaft fixedly connected to the bottom of the dual-axis motor, a housing provided on one side of the workbench, a horizontal plate provided at the central shaft of the inner cavity of the housing, the inner cavity of the horizontal plate being movably connected to the crankshaft, sealing plates fixedly connected to both sides of the horizontal plate, air guide pipes connected to the central shafts on both sides of the housing, a hollow block connected to one side of the air guide pipe, a filter plate inserted into one side of the hollow block, a corrugated pipe fixedly connected to the top of the hollow block, a dust suction head provided on one side of the corrugated pipe, a fixing rod fixedly connected to the bottom of the horizontal plate, an adjusting rod movably connected to one side of the fixing rod, a rotating shaft fixedly connected to one side of the adjusting rod, and a connecting shaft fixedly connected to the rear side of the dust suction head.

[0006] Preferably, a connecting cylinder is fixedly connected to the central axis at the top of the workbench, a drive shaft is fixedly connected to the top of the dual-axis motor, and a stirring rod is fixedly connected to the surface of the drive shaft.

[0007] Preferably, rectangular rods are fixedly connected to both the front and back of the housing, and the top of the rectangular rods is fixedly connected to the worktable.

[0008] Preferably, the front ends of both sides of the housing are connected to a second one-way valve, one side of the bellows is connected to a first one-way valve, and one side of the first one-way valve is connected to the vacuum head.

[0009] Preferably, a vertical plate is fixedly connected to the rear side of the workbench, and one side of the vertical plate is movably connected to the connecting shaft via a bearing.

[0010] Preferably, a synchronous pulley is fixedly connected to both the rear side of the connecting shaft and the surface of the rotating shaft, and a synchronous belt is engaged with the surface of the synchronous pulley.

[0011] Preferably, the front side of the bottom of the connecting cylinder is connected to a discharge pipe, and the bottom of the discharge pipe is threadedly connected to a cover plate.

[0012] Compared with the prior art, this utility model provides a sand mixer with dust removal function for bolster production, which has the following beneficial effects:

[0013] 1. In this invention, the material is poured into the inner cavity of the connecting cylinder, and then the dual-shaft motor is started. The dual-shaft motor drives the drive shaft to rotate, and the drive shaft drives the stirring rod to rotate, thus agitating the material.

[0014] 2. The dual-axis motor of this utility model also drives the crankshaft to rotate, which in turn drives the horizontal plate to move. The horizontal plate then drives the sealing plate to move. As the sealing plate moves to the right, it draws dust in through the air duct, corrugated pipe, and suction head on the left side, allowing the dust to enter the hollow block cavity on the left. As the horizontal plate moves to the left, it draws dust in through the air duct, corrugated pipe, and suction head on the right side, allowing the dust to enter the hollow block cavity on the right. The dust is then filtered out by the filter plate, preventing it from mixing with the outside air and affecting the working environment. Furthermore, the horizontal plate also drives the fixed rod to move, which in turn drives the adjusting rod to rotate. The adjusting rod then drives the rotating shaft to rotate, which in turn causes the connecting shaft to rotate. The connecting shaft then drives the suction head to rotate back and forth, resulting in a wide suction range. Attached Figure Description

[0026] The specific function of this technical solution is to pour the material into the inner cavity of the connecting cylinder 2, and then start the dual-shaft motor 3.

[0027] Working principle: Pour the material into the inner cavity of the connecting cylinder 2, then start the dual-shaft motor 3, which drives the drive shaft 21 to rotate, and the drive shaft 21 drives the stirring rod 22 to rotate, thus agitating the material.

[0028] The dual-axis motor 3 also drives the crankshaft 5 to rotate, which in turn drives the horizontal plate 6 to move. The horizontal plate 6 then drives the sealing plate 7 to move. As the sealing plate 7 moves to the right, it draws dust in through the air duct 8, corrugated pipe 11, and suction head 13 on the left side, causing the dust to enter the inner cavity of the hollow block 9 on the left. As the horizontal plate 6 moves to the left, it draws dust in through the air duct 8, corrugated pipe 11, and suction head 13 on the right side, causing the dust to enter the inner cavity of the hollow block 9 on the right. The dust is then filtered out by the filter plate 10, preventing it from mixing into the outside air and affecting the working environment. Furthermore, the horizontal plate 6 also drives the fixed rod 14 to move, which in turn drives the adjusting rod 15 to rotate. The adjusting rod 15 then drives the rotating shaft 16 to rotate, which in turn causes the connecting shaft 17 to rotate. The connecting shaft 17 then drives the suction head 13 to rotate back and forth, resulting in a wide suction range.
