Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding equipment, in particular to an automatic feeding device. Background Art
[0002] Sponge titanium is the raw material of titanium processing materials, generally light gray particles. In the titanium processing process, sponge titanium and powdered intermediate alloys need to be evenly mixed using a mixer. After the sponge titanium and the intermediate alloy are evenly mixed, a cylindrical material box is usually placed at the outlet of the mixer to discharge the evenly mixed sponge titanium and intermediate alloy into the material box, and then the material box is transported to the ingot casting equipment by a crane, and the evenly mixed sponge titanium and intermediate alloy in the material box are poured into the feed of the ingot casting equipment. However, when the crane transports the material box to the feed of the ingot casting equipment, it is necessary to manually control the tilting of the material box to pour out the sponge titanium and intermediate alloy in the material box, and then transport the material box away by the crane after the dumping is completed. This feeding method manually controls the tilting of the material box. First, the tilting speed of the material box is low, which makes the discharge speed slow and affects the feeding efficiency. Second, when the tilting of the material box is manually controlled, the worker stands next to the material box. If the traction rope hanging the material box breaks, the collapse of the material box will cause a serious safety accident and threaten the personal safety of the workers. Utility Model Content
[0003] The utility model aims to provide an automatic material discharging device to solve the problem that manual operation and tilting of the material box are required when discharging materials from the material box.
[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: an automatic discharging device, comprising a traction rod and a material box with an open top, a discharge port being arranged at the bottom of the material box, a sealing cover being arranged at the outer bottom of the material box for sealing the discharge port, and the size of the sealing cover is larger than the size of the discharge port, and a fixing frame is fixedly connected to the top of the material box; the bottom end of the traction rod vertically passes through the fixing frame and the discharge port and is fixedly connected to the sealing cover, and the traction rod and the fixing frame are slidably connected, and a fixing ring is fixedly connected to the top end of the traction rod.
[0005] The working principle of the utility model is as follows: when loading, the material box is placed at the discharge port of the mixer, and the material box is completely pressed on the cover under the gravity of the material box itself, and the cover completely blocks the discharge port at the bottom of the material box. The uniformly mixed sponge titanium and intermediate metal powder in the mixer enter the material box through the open top of the material box. After the material box is full, the crane is connected to the fixed ring through a traction rope or a hook, and then the fixed ring is lifted. Since the fixed ring is fixed to the top of the traction rod, and the bottom of the traction rod is fixedly connected to the cover set at the bottom of the material box, and the size of the cover is larger than the size of the discharge port, when the fixed ring is lifted, the fixed ring pulls the traction rod, and the traction rod pulls the cover, providing an upward traction force for the material box through the cover, and then pulling the material box upward. The downward gravity of the material box itself cooperates with the downward gravity of the raw materials in the material box, so that the material box and the cover are tightly buckled without any gap, so that the raw materials in the material box will not leak out through the discharge port. When the material box is moved to the feeding place of the ingot casting equipment, a support frame for supporting the material box is installed in advance at the feeding place of the ingot casting equipment, and the material box is placed on the support frame. At this time, the crane drives the traction rope or hook to continue to move downward, and no longer forms an upward traction on the fixed ring. At this time, the cover moves downward under the action of gravity and the weight of the raw materials in the material box to expose the discharge port of the material box. At this time, the raw materials in the material box flow out through the discharge port and fall to the feeding place of the ingot casting equipment. After the discharge is completed, the crane pulls up and drives the material box to move again through the fixed ring, traction rod and cover.
[0006] Beneficial effects of the utility model:
[0007] 1. Through the material box, traction rod and cover, under the action of its own weight, the material box is moved downward with the traction rod as the center until it is buckled with the cover. In this way, the discharge port can be closed, so that the material box can contain evenly mixed sponge titanium and intermediate metal to ensure that the raw materials will not leak.
[0008] 2. When discharging materials, the material box is first placed on the support frame, and the cover and the traction rod fixed on the cover are pushed by their own gravity and the weight of the raw materials to move the cover downward to expose the discharge port. In this way, the titanium sponge and intermediate metal in the material box can be discharged from the discharge port under the action of gravity, achieving the purpose of automatic discharging without manual operation, which not only saves discharging time but also ensures the safety of workers.
[0009] Furthermore, the fixing frame is a "cross"-shaped fixing frame, a limiting ring is integrally formed at the center of the fixing frame, and the traction rod passes through the limiting ring and is slidably connected to the limiting ring. The purpose is to ensure that the traction rod is not easily skewed during the traction process through the "cross"-shaped fixing frame, so as to prevent the material box containing the raw materials from pouring out the raw materials.
[0010] Furthermore, the bottom of the material box is in a round bucket shape, and the discharge port is arranged at the lowest point of the bottom of the material box. The purpose is to facilitate the discharge of the raw materials in the material box along the round bucket-shaped bottom of the material box through this arrangement, so as to avoid the residual raw materials in the material box.
[0011] Furthermore, the cover is a conical cover, the diameter of the bottom of the cover is larger than the diameter of the discharge port, the top of the cover is fixedly connected to the bottom of the traction rod, and the surface of the cover is perpendicular to the bottom of the material box. Through this arrangement, firstly, when discharging materials, the raw materials on the cover surface can slide down along its surface under the action of gravity, avoiding raw materials remaining on the cover surface; secondly, after the conical cover and the bucket-shaped bottom of the material box contact each other, the upward traction force can be decomposed into an upward pulling force and a supporting force perpendicular to the inclined surface of the cover, so that the direction of the supporting force is on the same plane as the inclined surface of the bottom of the material box, so that the material box can withstand more supporting force from the cover, so that the loading capacity of the material box for raw materials can be increased, or under the same loading capacity, the bottom of the material box is not easy to deform, thereby increasing the service life of the material box.
[0012] Furthermore, a plurality of vertical support rods are fixedly connected at intervals at the edge of the bottom of the cover, and the shape of the support rods matches the outer surface of the bottom of the material box. The purpose is to increase the contact surface between the cover and the material box through the support rods, increase the force-bearing area between the cover and the material box, and reduce the possibility of deformation of the cover or the material box due to excessive concentrated force.

[0016] The following is further described in detail through specific implementation methods:
[0017] The reference numerals in the drawings of the specification include: a fixing ring 1 , a traction rod 2 , a limiting ring 3 , a fixing frame 4 , a material box 5 , a sealing cover 6 , a supporting rod 7 , and a discharge port 8 .
[0018] The embodiment is basically as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown:
[0019] An automatic material discharge device includes a traction rod 2 and a material box 5 with an open top. The bottom of the material box 5 is in the shape of a round bucket. A discharge port 8 is provided at the lowest point of the bottom of the material box 5. A conical cover 6 is provided at the outer bottom of the material box 5. The diameter of the bottom of the cover 6 is greater than the diameter of the discharge port 8, and the surface of the cover 6 is perpendicular to the bottom of the material box 5. A fixing frame 4 is fixedly connected to the top of the material box 5. The fixing frame 4 is a "cross"-shaped fixing frame 4. A limiting ring 3 is integrally formed at the center of the fixing frame 4. The bottom end of the traction rod 2 vertically passes through the limiting ring 3 and the discharge port 8 and is welded to the top of the cover 6. The traction rod 2 and the limiting ring 3 are slidably connected. The top of the traction rod 2 is fixedly connected to a fixing ring 1. Multiple vertical support rods 7 are fixedly connected to the edge of the bottom of the cover 6 at intervals. The shape of the support rods 7 matches the outer surface of the bottom of the material box 5.
[0020] The specific implementation process is as follows:
[0021] When loading, place the material box 5 at the discharge port of the mixer. Under the action of the gravity of the material box 5 itself, the material box 5 is completely pressed on the cover 6. At this time, the cover 6 completely blocks the discharge port 8 at the bottom of the material box 5. The uniformly mixed titanium sponge and intermediate metal powder in the mixer enter the material box 5 through the open top of the material box 5. After the material box 5 is filled, use a crane to connect with the fixed ring 1 through a traction rope or a hook, and then lift the fixed ring 1. Since the fixed ring 1 is fixed to the top of the traction rod 2, and the bottom end of the traction rod 2 is fixedly connected to the cover 6 set at the bottom of the material box 5, and the size of the cover 6 is larger than the size of the discharge port 8, when the fixed ring 1 is lifted, the fixed ring 1 pulls the traction rod 2, and the traction rod 2 pulls the cover 6, providing upward traction for the material box 5 through the cover 6, thereby pulling the material box 5 upward. The downward gravity of the material box 5 cooperates with the downward gravity of the raw materials in the material box 5, so that the material box 5 and the cover 6 are tightly fastened without any gap, so that the raw materials in the material box 5 will not leak out through the discharge port 8. When the material box 5 is moved to the feeding place of the ingot casting equipment, a support frame for supporting the material box 5 is installed in advance at the feeding place of the ingot casting equipment, and the material box 5 is placed on the support frame. At this time, the crane drives the traction rope or hook to continue to move downward, and no longer forms an upward traction on the fixed ring 1. At this time, the cover 6 moves downward under the action of gravity and the weight of the raw materials in the material box 5 to expose the discharge port 8 of the material box 5. At this time, the raw materials in the material box 5 flow out through the discharge port 8 and fall to the feeding place of the ingot casting equipment. After the discharge is completed, the crane pulls up and drives the material box 5 to move again through the fixed ring 1, the traction rod 2 and the cover 6.
