Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses sand mixer. Referring to fig. 1, the roller mill includes barrel 1, roof 2, (mixing) shaft 3, impeller 4, support frame 5 places subaerial, 1 vertical the placing of barrel, 1 upper end opening of barrel, the lower extreme is sealed, barrel 1 supports in support frame 5's top and rotates with support frame 5 to be connected, 2 fixed connection of roof are in 1 upper end of barrel, mixing shaft 3 all is located barrel 1 with impeller 4, (mixing) shaft 3 is vertical to be placed, 3 upper ends of (mixing) shaft are rotated with roof 2 and are connected, 2 upsides of roof are provided with motor drive (mixing) shaft 3 and rotate, feed inlet 21 has still been seted up on roof 2, 3 lower extremes of (mixing) shaft and impeller 4. In the use process, the material is poured from the feeding hole 21, the motor drives the stirring shaft 3 to rotate in the barrel body 1, the stirring shaft 3 drives the impeller to complete sand mixing, then the stirring shaft 3 is stopped to rotate, the barrel body 1 is controlled to rotate to the feeding hole 21 downwards, and the processed material can be poured out from the feeding hole 21. Because the barrel 1 can rotate the ejection of compact, so 1 lower extreme of barrel of roller mill can set up and seal during the roller mill operation to can reduce the appearance of roller mill during operation hourglass sand condition.
The barrel 1 quality of being equipped with the material is great, for the convenience rotates barrel 1, refer to fig. 1, the barrel 1 outside can set up pivot 11, pivot 11 is provided with two, and two pivot 11 levels are placed and highly the same, and two pivot 11 are located same straight line, and 11 one end of pivot and 1 fixed connection of barrel, pivot 11 keep away from 1 one end of barrel and rotate with support frame 5 and be connected, are provided with the motor on support frame 5 and drive pivot 11 and rotate. An operator can control the motor to drive the rotating shaft 11 to rotate, and the rotating shaft 11 drives the barrel body 1 to rotate, so that the operation is convenient.
In order to reinforce the connection between the two side support frames 5, referring to fig. 1, a connection plate 51 may be disposed on the support frame 5, the connection plate 51 is located below the barrel 1, two ends of the connection plate 51 are respectively fixedly connected to the support frames 5 located at two sides of the barrel 1, and the connection plate 51 is located away from the rotating shaft 11 to drive the barrel 1 to rotate. The connection plate 51 increases the connection area of the support frames 5 at both sides of the cylinder 1, thereby reinforcing the support frames 5.
Since the connecting plate 51 is located below the barrel 1, the processed material will be stacked on the connecting plate 51, and the material stacked on the connecting plate 51 will be scattered around after increasing. In order to facilitate the collection of the processed material, referring to fig. 1, the connection plate 51 is disposed to be inclined. The material that drops on connecting plate 51 this moment will follow the lowest roll-off of connecting plate 51, and is comparatively clean and tidy, the collection of convenient processing back material.
Because the rotating shaft 11 needs to drive the cylinder 1 filled with the materials to rotate, and the cylinder 1 filled with the materials has larger mass, the joint of the rotating shaft 11 and the cylinder 1 is easy to deform or even break. In order to reinforce the joint of the rotating shaft 11 and the barrel 1, referring to fig. 2, a fixing block 12 is fixedly connected to the joint of the rotating shaft 11 and the barrel 1. The fixing block 12 reduces the possibility of deformation of the joint of the rotating shaft 11 and the barrel 1, thereby reinforcing the joint of the rotating shaft 11 and the barrel 1.
In order to reduce energy consumption, referring to fig. 2, the motor is provided with a speed reducer 13, and the motor drives the stirring shaft 3 and the rotating shaft 11 to rotate through the speed reducer 13. The speed reducer 13 can increase torque, so that the motor can achieve torque required by rotation with less electric energy consumption, and electric energy consumption is saved.
In order to make the sand mixer stir the material more sufficiently, referring to fig. 2, the blades 41 of the stirring impeller 4 may be provided in two layers, and the shape of the blade 41 positioned above is different from the shape of the blade 41 positioned below. When the stirring shaft 3 drives the stirring impeller 4 to rotate, the area of the blade 41 in contact with the material is increased, the shape of the blade 41 is changed, the material can be stirred more sufficiently by the sand mixer, and the sand mixing of the sand mixer is more uniform.
Because motor and speed reducer 13 have been placed to roof 2 upside, and roof 2 downside is connected with (mixing) shaft 3 and impeller 4, so roof 2 receives decurrent pulling force great, and barrel 1 upper end provides ascending holding power for roof 2, and roof 2 is less with barrel 1 upper end area of contact, probably can make roof 2 warp. In order to improve the above problem, referring to fig. 2, the upper end of the cylinder 1 is folded outwards to be horizontal, and the top plate 2 is fixedly connected with the upper side of the outward folded part of the cylinder 1. The contact area of the top plate 2 and the upper end of the cylinder 1 is increased, and the possibility of deformation of the top plate 2 is reduced.
Since the stirring impeller 4 receives a large resistance against rotation during the operation of the sand mixer, the stirring impeller 4 may be separated from the stirring shaft 3. In order to reinforce the joint of the stirring shaft 3 and the stirring impeller 4, referring to fig. 2, a connecting block 31 may be fixedly connected to the joint of the stirring shaft 3 and the stirring impeller 4. The connecting block 31 increases the connecting area of the stirring shaft 3 and the stirring impeller 4, and reinforces the connection of the stirring shaft 3 and the stirring impeller 4.
The implementation principle of the sand mixer in the embodiment of the application is as follows: pour into the material from feed inlet 21, motor drive (mixing) shaft 3 rotates in barrel 1, the (mixing) shaft 3 will drive the impeller and accomplish the mullion, then stop (mixing) shaft 3 and rotate, motor drive pivot 11 rotates, pivot 11 drives barrel 1 and rotates to feed inlet 21 down, the material after processing this moment can be poured out to connecting plate 51 from feed inlet 21 on, material landing on connecting plate 51 is outside to connecting plate 51, because the ejection of compact can be rotated to barrel 1, so 1 lower extreme of barrel of mulling machine can set up and seal during the mulling operation, thereby can reduce the appearance of the mulling machine during operation hourglass sand condition.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
