During the rotation of the storage box 201, the first guide wheel 2042 at the bottom of the storage box 201 is located on the unloading slide rail 206. Figure 6 and Figure 8As shown, at this time, the first sealing plug 2031 is separated from the discharge pipe 2012, and the raw material can flow into the discharge pipe 2012 through the gap. As the storage box 201 moves, the second guide wheel 3042 will move to the discharge notch 2061, and the return spring 2053 is in a compressed state, thereby driving the bottom slide plate 2051 and the insertion rod 2052 to slide downward, and the insertion rod 2052 drives the synchronous plate 204 and the push rod 203 to slide downward, and the push rod 203 can push the first The sealing plug 2031 and the discharge pipe 2012 are resealed, and the gap between the first sealing plug 2031 and the second sealing plug 2032 and the discharge pipe 2012 is filled with raw materials for discharge.

The content of each discharge is reduced, and the discharge can be carried out at different positions to ensure that the discharge is relatively uniform.

[0044] Embodiment 3: Based on the above embodiment, the difference between this embodiment and the present embodiment is that: Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a stirring rod 3021 is installed on the stirring shaft 302, and the stirring rod 3021 is distributed in a spiral shape. A bearing is sleeved on the rotating shaft 3012, and the bearing is clamped in the bearing seat 3013. The bearing seat 3013 is installed on the side wall of the storage box 201. A fixing column 3032 is installed at the bottom of the positioning rack 3031, and the fixing column 3032 is welded on the base 102. During the rotation of the storage box 201, the driving gear 303 at this time rolls on the positioning rack 3031, and the positioning rack 3031 is limited by the fixing column 3032, and then the driving gear 303 at this time will rotate, and the driving gear 303 drives the rotating shaft 3012 to rotate on the bearing seat 3013, and the coaxially connected stirring shaft 302 drives the spiral stirring rod 3021 to rotate, which can break up the raw materials inside the storage box 201 and reduce the phenomenon of agglomeration.

[0045] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in a specific embodiment, the outer shell of the force storage cover 305 is installed with a side plate 3051, and the side wall of the guide cover 2011 on one side of the side plate 3051 is interconnected, and a baffle 3061 is slidably arranged inside the force storage cover 305, one side of the baffle 3061 is interconnected with the pull rod 306, and the other side of the baffle 3061 is interconnected with the hammer rod 3063, and a hammer head 3064 is installed at the end of the hammer rod 3063, and a force storage spring 3062 is sleeved on the pull rod 306, one end of the force storage spring 3062 is clamped on the baffle 3061, and the other side is clamped on the inner wall of the force storage cover 305. When the pull plate 304 drives the pull rod 306 to slide inside the force storage cover 305, the baffle 3061 inside the force storage cover 305 slides synchronously to compress the force storage spring 3062, and the hammer rod 3063 and the discharge pipe 2012 are separated. When the pull plate 304 moves to the vertical surface of the right triangle of the protrusion 3011, the compressed force of the force storage spring 3062 is released, driving the baffle 3061 to reset, so that the hammer rod 3063 and the hammer head 3064 quickly collide with the discharge pipe 2012, thereby vibrating the discharge pipe 2012, accelerating the flow of raw materials inside the storage box 201, and reducing the occurrence of blockages.

[0046] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, further, a fixing seat 3045 is installed on the side plate 3051, a limiting rod 3043 is installed on the fixing seat 3045, the limiting rod 3043 movably penetrates the pull plate 304, a limiting plate 3044 is installed at the end of the limiting rod 3043, a positioning frame 3041 is installed on the pull plate 304, a second guide wheel 3042 is installed on the positioning frame 3041, and the second guide wheel 3042 corresponds to the protrusion 3011. During the sliding process of the pull plate 304, the pull plate 304 slides along the limiting rod 3043, and the limiting plate 3044 limits the maximum distance of the pull plate 304 to ensure that the pull plate 304 will not leave the current position.

[0047] The implementation principle of a feeding device for silicon carbide micropowder mixed slurry in this embodiment is as follows:

[0048] First, the four storage boxes 201 need to be filled with the raw materials that need to be fed.

[0049] Then the operator starts the drive motor 202, which drives the transmission shaft 2021 to rotate. The side wall of the transmission shaft 2021 is connected to a synchronization rod 2022. At this time, the synchronization rod 2022 drives the four connected storage boxes 201 to start rotating, and the position of the discharge pipe 2012 at the bottom of the storage box 201 keeps changing, so that feeding operations can be performed at different positions.

[0050] During the rotation of the storage box 201, the first guide wheel 2042 at the bottom of the storage box 201 is located on the unloading slide rail 206. Figure 6 and Figure 8 As shown, at this time, the first sealing plug 2031 is separated from the discharge pipe 2012, and the raw material can flow into the discharge pipe 2012 through the gap. As the storage box 201 moves, the second guide wheel 3042 will move to the discharge notch 2061, and the return spring 2053 is in a compressed state, thereby driving the bottom slide plate 2051 and the insertion rod 2052 to slide downward, and the insertion rod 2052 drives the synchronous plate 204 and the push rod 203 to slide downward, and the push rod 203 can push the first The sealing plug 2031 and the discharge pipe 2012 are resealed, and the gap between the first sealing plug 2031 and the second sealing plug 2032 and the discharge pipe 2012 is filled with raw materials for discharge. When the second guide wheel 3042 moves to the lowest point, the second sealing plug 2032 can be separated from the discharge pipe 2012, and the raw materials inside the discharge pipe 2012 can be discharged outward, completing the purpose of discharge. The content of each discharge is reduced, and the discharge can be carried out at different positions to ensure that the discharge is relatively uniform.

[0051] During the rotation of the storage box 201, the driving gear 303 rolls on the positioning rack 3031, and the positioning rack 3031 is limited by the fixed column 3032, so that the driving gear 303 will rotate. The driving gear 303 drives the rotating shaft 3012 to rotate on the bearing seat 3013, and the coaxially connected stirring shaft 302 drives the spiral stirring rod 3021 to rotate, which can break up the raw materials inside the storage box 201 and reduce the agglomeration phenomenon.

[0052] The rotation of the rotating shaft 3012 can drive the rotating disk 301 to rotate, and the position of the protrusion 3011 moves synchronously at this time. The protrusion 3011 is a right triangle, and then the inclined surface of the protrusion 3011 contacts the second guide wheel 3042 at this time. At this time, the second guide wheel 3042 moves outward synchronously, and then the second guide wheel 3042, the positioning frame 3041 and the pull plate 304 move outward, and the pull plate 304 drives the pull rod 306 to slide inside the power storage cover 305, and the baffle 3061 inside the power storage cover 305 slides synchronously , the force storage spring 3062 is compressed, and the hammer rod 3063 and the discharge pipe 2012 are separated. When the second guide wheel 3042 moves to the right-angled triangle vertical surface of the protrusion 3011, the compressed force of the force storage spring 3062 is released, driving the baffle 3061 to reset, so that the hammer rod 3063 and the hammer head 3064 quickly collide with the discharge pipe 2012, thereby vibrating the discharge pipe 2012, accelerating the flow of raw materials inside the storage box 201, and reducing the occurrence of blockage.

[0053] During the sliding process, the pull plate 304 slides along the limiting rod 3043 , and the limiting plate 3044 limits the maximum moving distance of the pull plate 304 to ensure that the pull plate 304 does not deviate from the current position.
