DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2The utility model provides a new type of composite sand preparation device for high-performance casting, including a mixing preparation container 1, the bottom of the mixing preparation container 1 is supported on the ground by a tripod 8, a rotating transmission mechanism 2 is fixedly installed at the bottom of the inner wall of the mixing preparation container 1, a motor 4 is fixedly installed at the bottom of the mixing preparation container 1, and the output end of the motor 4 is connected to a turntable 3 through the rotating transmission mechanism 2. The turntable 3 is arranged on the top of the rotating transmission mechanism 2, and a plurality of rotary arms 5 are fixedly connected to the side wall of the turntable 3. One side of the rotary arm 5 is an inclined surface. There is a gap between the bottom of the inner wall of the mixing preparation container 1 and the bottom of the rotary arm 5, and a crushing and feeding mechanism 7 is fixedly connected to the inner wall of the mixing preparation container 1, and the turntable 3 is connected to the crushing and feeding mechanism 7.

[0025] Reference Figure 3 The crushing feeding mechanism 7 includes a crushing container 71, the side wall of the crushing container 71 is fixedly connected to the inner wall of the mixing preparation container 1 through two connecting plates 72, a rotating column 73 is movably sleeved inside the crushing container 71, the bottom end of the rotating column 73 penetrates the crushing container 71 and is connected to the top of the rotating disk 3, the side wall of the rotating column 73 is fixedly connected to a rotating table 74, the side wall of the rotating table 74 is fixedly connected to a plurality of crushing movable plates 75, the side wall of the crushing movable plate 75 is provided with a plurality of notches, the inner wall of the crushing container 71 is fixedly connected to a plurality of groups of crushing static plates 76, the number of each group of crushing static plates 76 matches the number of notches on the side wall of a single crushing movable plate 75, and the size of the crushing static plates 76 matches the size of the notches on the crushing movable plates 75, and there is a one-centimeter gap between the bottom of the crushing movable plate 75 and the bottom of the inner wall of the crushing container 71 The bottom of the crushing container 71 is provided with a plurality of filter holes 77. When the equipment is running for mixing, the rotary disk 3 rotates. At this time, the rotary disk 3 drives the rotary column 73 to rotate, and the rotary table 74 is driven to rotate by the rotary column 73, so that a plurality of crushing movable plates 75 are circled, and the agglomerated materials are placed inside the crushing container 71. The agglomerated raw materials are moved by the crushing movable plates 75 until they contact with the crushing static plates 76. The crushing static plates 76 can pass through the grooves on the side walls of the crushing movable plates 75. In this process, the crushing static plates 76 have a crushing effect on the agglomerated materials. The crushed materials reach the bottom of the crushing movable plates 75, and the crushing movable plates 75 further crush the raw materials when they are circled. The crushed raw materials pass through the filter holes 77 to achieve the effect of feeding into the mixing preparation container 1.

[0026] Reference Figure 3 The two sides of the crushing static plate 76 are edges, so that when the crushing static plate 76 contacts the agglomerated raw materials, the edges contact the raw materials, which can exert a greater pressure on the raw materials to achieve a better crushing effect.

[0027] Reference Figure 4The rotary arm 5 includes a main arm body 51, and a plurality of arc-shaped knife grooves 52 are opened at the bottom of the main arm body 51. A plurality of groups of arc-shaped blades 6 are fixedly connected to the bottom of the inner wall of the mixing preparation container 1. The number of arc-shaped blades 6 in each group matches the number of arc-shaped knife grooves 52 at the bottom of the main arm body 51. During the orbiting process of the rotary arm 5, the arc-shaped blades 6 can pass through the arc-shaped knife grooves 52 at the bottom of the main arm body 51. When the raw materials being mixed have lumps, the arc-shaped blades 6 cooperate with the main arm body 51 to squeeze the lumps, and the lumps can be broken by the arc-shaped blades 6 passing through the arc-shaped knife grooves 52.

[0028] Reference Figure 5 The top of the arc blade 6 is an edge, one end of the arc blade 6 is tapered, and the other end is a triangular surface. The triangular surface at the other end of the arc blade 6 is adapted to the size of the arc groove 52. Due to the shape characteristics of the arc blade 6, when the arc blade 6 contacts the agglomerate, a large pressure can be applied to the agglomerate through the tapered surface at one end of the arc blade 6 and the top edge, thereby achieving a good crushing effect.

[0029] Reference Figure 4 A plurality of wheel grooves are provided at the bottom of the rotary arm 5, and solid wheels 53 are movably sleeved in the plurality of wheel grooves. When the raw materials pass through the bottom of the main arm body 51, the solid wheels 53 can crush the raw materials, so that the prepared composite sand is finer.

[0030] Reference Figure 6 The rotary transmission mechanism 2 includes a fixed shell 21, which is fixedly connected to the bottom of the inner wall of the mixing preparation container 1. An inner shaft 22 is movably sleeved inside the fixed shell 21, and a connecting pin 24 is movably sleeved on the top of the fixed shell 21. The bottom end of the connecting pin 24 passes through the fixed shell 21 and is connected to the top of the inner shaft 22. The bottom end of the inner shaft 22 passes through the fixed shell 21 and is connected to the output shaft of the motor 4. The inner shaft 22 is driven to rotate by the output of the motor 4, and the connecting pin 24 is driven to rotate by the inner shaft 22. The turntable 3 is driven to rotate by the connecting pin 24, thereby achieving the transmission effect of the rotary transmission mechanism 2, and the fixed shell 21 has a certain supporting and load-bearing effect on the turntable 3.

[0031] Reference Figure 6 A flywheel 23 is disposed inside the fixed shell 21 and is fixedly connected to the side wall of the inner shaft 22. When the flywheel 23 rotates following the inner shaft 22, the rotational inertia of the flywheel 23 overcomes the resistance of the rotating arm 5.

[0032] The working principle of the utility model is as follows: when in use, the motor 4 provides power, and the rotary disc 3 is rotated under the transmission effect of the rotating transmission mechanism 2, and the rotary disc 3 drives a plurality of rotary arms 5 to circle, so as to achieve a mixing effect on the materials inside the mixing and preparing container 1. Since one side of the rotary arm 5 is an inclined surface, when the rotary arm 5 contacts the materials, the materials can be guided downward along the inclined surface of the rotary arm 5. When the materials pass through the gap between the bottom of the rotary arm 5 and the bottom of the inner wall of the mixing and preparing container 1, the materials with larger particles are squeezed and crushed, thereby improving the preparation quality of the composite sand. When adding raw materials, the materials can be fed through the crushing and feeding mechanism 7. When the rotary disc 3 rotates, the crushing and feeding mechanism 7 is operated, which can achieve a crushing effect on the materials for pre-treatment, and avoid the raw materials from agglomerating and being unable to participate in mixing.
