[0031] Please refer to the attached Figure 1-2 , a detachable rotary tillage and mixing device for fuel separate addition provided in an embodiment of the present invention includes a mixing mechanism 10, a support mechanism 20, and a driving component 30. First of all, it should be noted that different from the fuel separate addition devices in the prior art which are commonly used for field rotary tillage operations, different from rotary tilling the soil, the main materials in the fuel separate addition device are iron ore powder, coal powder, etc., and the resistance during rotary tillage is large, and it will accelerate the wear of the cutting tools. This application solves the above defects in the prior art by setting a detachable rotary tillage and mixing device for fuel separate addition, specifically as follows:
[0032] The mixing mechanism 10 includes a mixing shaft 110 and a plurality of rotary tillage tool units 120 arranged at intervals along the axial direction of the mixing shaft 110. Each rotary tillage tool unit 120 includes a flange plate 121 and a plurality of rotary tillage tools 122 arranged at intervals along the circumferential direction of the flange plate 121; wherein, the mixing shaft 110 is rotatably connected to the support mechanism 20, and one end of the mixing shaft 110 is connected to the driving end of the driving component 30; the flange plate 121 is sleeved on the mixing shaft 110, the rotary tillage tool 122 is detachably connected to the flange plate 121, the rotary tillage tool 122 is arranged in a bent shape, and the bending directions of every two adjacent rotary tillage tools 122 along the circumferential direction are opposite.
[0033] Specifically, the detachable rotary tillage mixing device for fuel addition in the present application includes a mixing mechanism 10, a support mechanism 20 and a drive assembly 30. The mixing mechanism 10 is used to mix the surface fuel and the mixture of the sintering machine. The support mechanism 20 is used for the installation of the mixing mechanism 10 so that the mixing mechanism 10 can be rotatably installed on the support mechanism 20, thereby achieving the stirring and mixing effect, and the drive assembly 30 is used as a power source for the rotation of the mixing mechanism 10 to drive the mixing mechanism 10 to rotate. It can adopt a reduction motor, etc., and technical personnel in this field can choose according to their needs.
[0034] Wherein, the mixing mechanism 10 includes a mixing shaft 110 and a plurality of rotary tillage tool units 120, the mixing shaft 110 is used to rotate to drive the rotary tillage tool unit 120 to rotate, and is rotatably connected to the support mechanism 20, and one end thereof is connected to the driving end of the drive assembly 30, so that the driving assembly 30 drives the mixing shaft 110 to rotate under the rotation of the driving assembly 30; and a plurality of the rotary tillage tool units 120 are arranged at axial intervals along the mixing shaft 110 to ensure that mixing can be performed within a sufficient range to ensure a better mixing effect, wherein each of the rotary tillage tool units 120 includes a method A flange plate 121 and a plurality of rotary tilling tools 122 are arranged at intervals along the circumference of the flange plate 121. The flange plate 121 is used for installing the rotary tilling tools 122. It is realized by being sleeved on the mixing shaft 110 so as to rotate along with the mixing shaft 110, and the rotary tilling tools 122 are detachably connected to the flange plate 121 by bolt connection. This makes it more convenient to replace the tools when they are worn. Furthermore, two connecting holes are provided at the bottom of each of the rotary tilling tools 122 to ensure that the rotary tilling tools 122 are more firmly connected when connected with bolts to avoid falling off and damage during rotation.
[0035] Among them, the rotary tillage tool 122 is set in a bent shape, which can increase the different contact surfaces between the tool and the mixture, thereby dispersing the direction of the stirring force and making the mixing effect better. In a preferred embodiment, every two adjacent rotary tillage tools 122 along the circumference are respectively arranged on both sides of the flange plate 121, and the bending directions of every two adjacent rotary tillage tools 122 along the circumference are opposite. Such a positive and negative layout can make the mixing shaft 110 balanced in axial force to avoid large vibration, thereby extending the life of the transmission parts and the mixing shaft 110 and ensuring a stable working state during the mixing operation; and when bending, each rotary tillage tool 122 is bent upward from one side of the flange plate 121 toward the other side of the flange plate 121, so that the pressure during mixing is all toward the flange plate 121. After the rotary tillage tool 122 is subjected to partial pressure toward the flange, the connection effect is more stable, avoiding the tool loosening.
[0036] As a relatively preferred embodiment of the present utility model, the bending angle of the rotary tillage tool 122 is 100° to 120°.
[0037] It should be noted that setting the bending angle of the rotary tillage tool 122 in an obtuse angle form can better increase the rotary tillage and mixing strength of the tool, and such an outward expansion form can better increase the mixing range and improve the mixing effect.
[0038] As a preferred embodiment of the present utility model, the number of the rotary tillage tools 122 in each rotary tillage tool unit 120 is six, and the six rotary tillage tools 122 are arranged at intervals along the circumferential direction of the flange plate 121, and the interval angle between two adjacent rotary tillage tools 122 in each rotary tillage tool unit 120 is 60°.
[0039] It is worth noting that the more the number of the rotary tillage tools 122 in each rotary tillage tool unit 120, the better the mixing effect. However, considering the production cost, the mixing strength required for mixing, and the rationality of production and installation, preferably, the number of the rotary tillage tools 122 in each rotary tillage tool unit 120 is six. And arranging the six rotary tillage tools 122 at intervals along a 60° circumference can ensure uniform distribution, thereby ensuring the structural stability during the mixing operation and ensuring the mixing effect.
[0040] As a preferred embodiment of the present utility model, the rotary tillage tools 122 between two adjacent rotary tillage tool units 120 are arranged staggeredly along the circumferential direction of the mixing shaft 110.
[0041] It should be noted that here it means that two adjacent rotary tillage tool units 120 are installed by rotating a certain angle, so that the rotary tillage tools 122 between two adjacent rotary tillage tool units 120 are not on the same axis position, forming a staggered form. Such an arrangement can halve the number of tools that are simultaneously subjected to the same-direction force for rotary tillage, so as to reduce the torque required by the transmission components and improve the operation efficiency; preferably, since the interval angle between two adjacent rotary tillage tools 122 in each rotary tillage tool unit 120 is 60°, two adjacent rotary tillage tool units 120 can be installed by rotating 30°, thereby forming a staggered installation structure form.
[0042] Furthermore, the support mechanism 20 includes a base 210 and two bearing seats 220 that are oppositely arranged along the axial direction of the mixing shaft 110. One of the bearing seats 220 is fixed on the base 210, and both ends of the mixing shaft 110 are respectively rotatably connected to the bearing seats 220, and one end of the mixing shaft 110 extends out of the bearing seat 220.
[0043] It should be noted that the bearing housing 220 is used for the rotatable connection and installation of the mixing shaft 110, and one end of the mixing shaft 110 is used for connection with the drive assembly 30 (reduction motor). Therefore, the amplitude range caused by its rotation has a greater impact. Thus, to ensure the structural stability during rotation, a base 210 is added under the bearing housing 220 where the drive assembly 30 is connected to improve stability, so that one of the bearing housings 220 is fixed on the base 210, and the connected drive assembly 30 can also be fixed on the base 210; among them, the end of the mixing shaft 110 for connection with the drive assembly 30 extends out of the bearing housing 220, which can be more convenient for connection with the drive assembly 30.
[0044] Furthermore, a coupling 230 is further included, and one end of the mixing shaft 110 is connected to the drive end of the drive assembly 30 through the coupling 230.
[0045] It should be understood that the coupling 230 can transmit torque and motion, enabling two shafts to work together, and can also compensate for the offset between the two shafts, reduce shaft vibration and noise, and improve transmission efficiency.
[0046] Furthermore, the number of the rotary tillage tool units 120 is six, and the six rotary tillage tool units 120 are arranged at intervals along the axial direction of the mixing shaft 110.
[0047] It should be noted that the number of the rotary tillage tool units 120 can be determined by combining the length of the mixing shaft 110 and the required mixing intensity. In a preferred embodiment of the present application, the number of the rotary tillage tool units 120 is six.
[0048] Furthermore, the distance between two adjacent rotary tillage tool units 120 is 150 mm to 250 mm.
[0049] It can be understood that by arranging the rotary tillage tool units 120 at intervals within a specific preferred range, it can ensure that mixing is carried out within a sufficient working range. Therefore, the distance between two adjacent rotary tillage tool units 120 can be set to 150 mm to 250 mm. Preferably, it can be set to 200 mm, and those skilled in the art can select according to actual needs.
[0050] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
